3 SCons - a software construction tool
7 NOTE: The 4.0.0 Release of SCons dropped Python 2.7 Support
8 NOTE: 4.3.0 now requires Python 3.6.0 and above. Python 3.5.x is no longer supported
10 RELEASE VERSION/DATE TO BE FILLED IN LATER
13 - GetSConsVersion() to grab the latest SCons version without needing to
14 dig into private functions.
17 - Fix issue #3935: OSErrors are now no longer hidden during execution of
18 Actions. All exceptions during the execution of an Action are now
19 returned by value rather than by raising an exception, for more
21 NOTE: With this change, user created Actions should now catch and handle
22 expected exceptions (whereas previously many of these were silently
23 caught and suppressed by the SCons Action exection code).
26 - Updated Value Node docs and tests.
27 - Python 3.13 compat: re.sub deprecated count, flags as positional args,
28 caused update-release-info test to fail.
29 - Dump() with json format selected now recognizes additional compound types
30 (UserDict and UserList), which improves the detail of the display.
31 json output is also sorted, to match the default display.
32 - Python 3.13 (alpha) changes the behavior of isabs() on Windows. Adjust
33 SCons usage of in NodeInfo classes to match. Fixes #4502, #4504.
34 - Drop duplicated __getstate__ and __setstate__ methods in AliasNodeInfo,
35 FileNodeInfo and ValueNodeInfo classes, as they are identical to the
36 ones in parent NodeInfoBase and can just be inherited.
37 - Update manpage for Tools, and for TOOL, which also gets a minor
38 tweak for how it's handled (should be more accurate in a few situations).
39 - Documentation build now properly passes through skipping the PDF
40 (and EPUB) builds of manpage and user guide; this can also be done
41 manually if directly calling doc/man/SConstruct and doc/user/SConstruct
42 by adding SKIP_PDF=1. This should help with distro packaging of SCons,
43 which now does not need "fop" and other tools to be set up in order to
44 build pdf versions which are then ignored.
45 - Add the ability to print a Variables object for debugging purposes
46 (provides a __str__ method in the class).
49 RELEASE 4.7.0 - Sun, 17 Mar 2024 17:22:20 -0700
51 From Ataf Fazledin Ahamed:
52 - Use of NotImplemented instead of NotImplementedError for special methods
53 of _ListVariable class
56 - Fix issue #2755: the msvs tool no longer writes the OS environment SCONS_HOME
57 value into the SCons environment when the SCONS_HOME variable already exists
58 in the SCons environment. Prior to this change, a valid user-defined SCons
59 environment value for SCONS_HOME would be overwritten with the OS environment
60 value of SCONS_HOME which could be None (i.e., undefined).
61 - Update the windows registry keys for detection of Visual Studio 2015 Express
62 ('14.0Exp'): the VS2015 registry key ('WDExpress') appears to be different
63 than the registry key ('VCExpress') for earlier Visual Studio express
64 versions. The registry key value is relative to the installation root rather
65 than the VC folder and requires additional path components during evaluation.
66 - Fix the vs-6.0-exec.py test script: the msvs generated project is 'foo.dsp'
67 and the command-line invocation of the Visual Studio development environment
68 program was attempting to build 'test.dsp'. The command-line invocation was
69 changed to build 'foo.dsp'.
70 - Update the msvs project generation test scripts: the msvs project execution
71 tests could produce a "false positive" test result when the test executable is
72 correctly built via the SConstruct env.Program() call and the command-line
73 invocation of the Visual Studio development environment program fails. The
74 test passes due to the existence of the test executable from the initial
75 build. The tests were modified to delete the test executable, object file,
76 and sconsign file prior to the command-line invocation of the VS development
78 - Method unlink_files was added to the TestCmd class that unlinks a list of
79 files from a specified directory. An attempt to unlink a file is made only
80 when the file exists; otherwise, the file is ignored.
81 - Fix issue #4320: add an optional argument list string to configure's CheckFunc
82 method so that the generated function argument list matches the function's
83 prototype when including a header file.
86 - Explicitly wrap non-serializable values in json dump
87 - Implemented SCons.Util.sctyping as a safe means of hinting complex types. Currently
88 only implemented for `Executor` as a proof-of-concept.
91 - Fix sphinx config to handle SCons versions with post such as: 4.6.0.post1
94 - Remove unnecessary dependencies on pypi packages from setup.cfg
97 - Fix of the --debug=sconscript option to return exist statements when using return
98 statement with stop flag enabled
100 From Prabhu S. Khalsa:
101 - Fix typo in user documentation (issue #4458)
104 - The NewParallel scheduler is now the default, the `tm_v2` flag is removed,
105 and the old scheduler is opt-in under `--experimental=legacy_sched`. Additionally,
106 the new scheduler is now used for -j1 builds as well.
107 - A python interpreter with support for the `threading` package is now required,
108 and this is enforced on startup. SCons currently sets its minimum supported
109 Python to 3.6, and it was not until Python 3.7 where `threading` became
110 default supported. In practice, we expect most real world Python 3.6 deployments
111 will have `threading` support enabled, so this will not be an issue.
112 - CacheDir writes no longer happen within the taskmaster critical section,
113 and therefore can run in parallel with both other CacheDir writes and the
115 - The NewParallel scheduler now only adds threads as new work requiring execution
116 is discovered, up to the limit set by -j. This should reduce resource utilization
117 when the achievable parallelism in the DAG is less than the -j limit.
120 - Add support for Python 3.13 (as of alpha 2). So far only affects
121 expected bytecodes in ActionTests.py.
122 - sconsign cleanup - remove some dead code, minor manpage tweaks.
123 - Be more cautious about encodings fetching command output on Windows.
124 Problem occurs in piped-spawn scenario, used by Configure tests.
126 - Clarify/fix documentation of Scanners in User Guide and Manpage.
128 - Fix bad typing in Action.py: process() and strfunction().
129 - Add Pseudo() to global functions, had been omitted. Fixes #4474.
130 - Improve handling of file data that SCons itself processes - try
131 harder to decode non-UTF-8 text. SCons.Util.to_Text now exists
132 to convert a byte stream, such as "raw" file data. Fixes #3569, #4462.
133 The Pseudo manpage entry was updated to provide more clarity.
134 - Clarify how SCons finds the project top directory, and what that is used for.
135 - The internal routine which implements the PyPackageDir function
136 would fail with an exception if called with a module which is
137 not found. It will now return None. Updated manpage entry and
139 - Doc update: standardized on the use of a new entity &MSVC; to
140 describe the Microsoft C++ compiler. Update the version table slightly.
141 Amplified the usage of MSVC_VERSION.
142 - Improve SharedLibrary docs a bit.
143 - More consistent use of &Python; in the manpage. A few links added.
144 A warning about overwriting env['ENV'] and one about Configure
145 checks possibly not running in in no-exec mode also added.
146 - Update warnings module: adds docstrings, drop three unused warnings
147 (DeprecatedSourceCodeWarning, TaskmasterNeedsExecuteWarning,
148 DeprecatedMissingSConscriptWarning) add two warnings to manpage
149 (cache-cleanup-error, future-reserved-variable), improve unittest, tweak
151 - Add locking around creation of CacheDir config file. Fixes #4489.
152 - Clarify MergeFlags usage of a dict argument.
153 - SCons documentation build can now be controlled through SKIP_DOC
154 variable - rather than just true/false can now specify
155 skip none, skip all, skip pdf docs, skip api docs.
158 RELEASE 4.6.0 - Sun, 19 Nov 2023 17:22:20 -0700
161 - Add missing directories to searched paths for mingw installs
164 - Fix issue #4312: the cached installed msvc list had an indirect dependency
165 on the target architecture in the environment dictionary. The first call
166 to construct the installed msvc list now forces the target architecture to be
167 undefined, constructs the installed msvc list, and then restores the original
169 Note: an indirect dependency on the VSWHERE construction variable in the
171 - Fix issue #4312: explicitly guard against an empty regular expression list
172 when msvc is not installed.
173 - When trying to find a valid msvc batch file, check that the compiler executable
174 (cl.exe) exists for VS6 to VS2015 to avoid executing the msvc batch file. Always
175 check that the compiler executable is found on the msvc script environment path
176 after running the msvc batch file. Only use the sdk batch files when all of the
177 msvc script host/target combinations have been exhausted and a valid script was
179 - Add ARM64 host configurations for windows and msvc.
180 Note: VS2013 and earlier has not been tested on ARM64.
181 - If necessary, automatically define VSCMD_SKIP_SENDTELEMETRY for VS2019 and later
182 on ARM64 hosts when using an arm32 build of python to prevent a powershell dll
183 not found error pop-up window.
184 - Fix an issue where test SConfTests.py would fail when mscommon debugging
185 was enabled. The mscommon debug filter class registered with the logging
186 module was refactored.
187 - Add arm64 to the MSVS supported architectures list for VS2017 and later to be
188 consistent with the current documentation of MSVS_ARCH.
189 - Fix an issue with an unhandled MissingConfiguration exception due to an msvc
190 registry query that returns a path that does not exist. Multiple invocation
191 paths were not prepared to handle the MissingConfiguration exception. The
192 MissingConfiguration exception type was removed.
193 - The MSCommon module import was changed from a relative import to a top-level
194 absolute import in the following Microsoft tools: midl, mslib, mslink, mssdk, msvc,
195 msvs. Moving any of these tools that used relative imports to the scons site tools
196 folder would fail on import (i.e., the relative import paths become invalid when
198 - The detection of the msvc compiler executable (cl.exe) has been modified:
199 * The host os environment path is no longer evaluated for the existence of the
200 msvc compiler executable when searching the detection dictionary.
201 * The existence of the msvc compiler executable is checked in the detection
202 dictionary and the scons ENV path before the detection dictionary is merged
204 * Different warnings are produced when the msvc compiler is not detected in the
205 detection dictionary based on whether or not an msvc compiler was detected in
206 the scons ENV path (i.e., a msvc compiler executable already exists in the
207 user's ENV path prior to detection).
208 * The warning message issued when a msvc compiler executable is not found in the
209 detection dictionary was modified by adding the word "requested":
210 Old warning: "Could not find MSVC compiler 'cl'."
211 New warning: "Could not find requested MSVC compiler 'cl'.".
212 * An additonal sentence is appended to the warning message issued when an msvc
213 compiler executable is not found in the msvc detection dictionary and is found
214 in the user's ENV path prior to detection:
215 " A 'cl' was found on the scons ENV path which may be erroneous."
217 From Vitaly Cheptsov:
218 - Fix race condition in `Mkdir` which can happen when two `SConscript`
219 are processed simultaneously by two separate build commands.
222 - The --debug flag now has a 'json' option which will write information
223 generated by --debug={count, memory, time, action-timestamps} and about
225 - Obsoleted YACCVCGFILESUFFIX, being replaced by YACC_GRAPH_FILE_SUFFIX.
226 If YACC_GRAPH_FILE_SUFFIX is not set, it will respect YACCVCGFILESUFFIX.
229 - The newly added --debug=sconscript option (new) will output notices when
230 entering an exiting each SConscript as they are processed.
232 From Philipp Maierhöfer:
233 - Fix gfortran tool initialization. Defaults to using binary named gfortran
234 as would be expected, and properly set's SHFORTRAN flags to include -fPIC
235 where previously it was only doing so for the other fortran versions (F77,..)
237 From Jonathon Reinhart:
238 - Fix another instance of `int main()` in CheckLib() causing failures
239 when using -Wstrict-prototypes.
242 - C scanner's dictifyCPPDEFINES routine did not understand the possible
243 combinations of CPPDEFINES - not aware of a "name=value" string either
244 embedded in a sequence, or by itself. The conditional C scanner thus
245 did not always properly apply the defines. The regular C scanner does
246 not use these, so was not affected. [fixes #4193]
247 - Minor cleanup for ValidateOptions - docs and docstring tweaked,
248 add missed versionadded indicator.
249 - Added some typing annotations generated by a tool, to eliminate manual
250 work in future on things which are safe for the tool to produce.
251 Then manually fixed up some things related to bool that the tool did
252 not handly ideally. For example, simple functions which just did
253 "return 1" were interpreted by the tool as returning int, when bool
254 was really the intent. Functions/methods named like "is_*", "has_*",
255 "exists" are now pretty consistently marked as "-> bool".
256 - Simplify some code due to pylint observation: "C2801: Unnecessarily
257 calls dunder method __call__. Invoke instance directly."
258 - Python 3.9 dropped the alias base64.decodestring, deprecated since 3.1.
259 Only used in msvs.py. Use base64.decodebytes instead.
260 - When debugging (--debug=pdb), the filenames SConstruct and SConscript
261 are now recognized when manipulating breakpoints. Previously,
262 only a full pathname to an sconscript file worked, as pdb requires
263 a .py extension to open a file that is not an absolute path.
264 - SCons test runner now uses pathlib to normalize and compare paths
266 - D compilers : added support for generation of .di interface files.
267 New variables DI_FILE_DIR, DI_FILE_DIR_PREFIX, DI_FILE_DIR_SUFFIX,
269 - Fixed: when using the mingw tool, if an msys2 Python is used (os.sep
270 is '/' rather than the Windows default '\'), certain Configure checks
271 could fail due to the construction of the path to run the compiled check.
272 - Added effort to find mingw if it comes from Chocolatey install of msys2.
273 - Minor doc fixes: signature of Alias() now matches implementation
274 to avoid problem if kwargs used; case of Alias with no targets is
275 mentioned in text (was already shown in example); now mention that
276 Action([item]) does not return a ListAction - previously implied
277 that if arg was a list, a ListAction was *always* returned; mention
278 default Decider and sort the names of available decider functions,
279 and add a version marking. Minor fiddling with Alias.py docstrings.
280 - Python 3.12 support: new bytecodes for ActionTests.py, adapt to
281 changes to pathlib module in runtest.py (PosixPath no longer
282 converts slashes if given a Windows-style path). Also switch to
283 using `subTest` in `ActionTests`, so that we can see all 21 fails
284 due to bytecode changes (previously testcases aborted on the first
285 assert fail so we only saw seven), and use unittest asserts to
286 simplify complex printing stanzas.
287 - Added copyright headers to files in test/ that didn't have them.
288 - Drop three unused methods from the Environment Base class:
289 get_src_sig_type and get_tgt_sig_type, as well as "private"
290 _changed_source. These were orphaned when the long-deprecated
291 Source Signatures and Target Signatures were removed, these were
293 - Remove dead code: some mocked classes in unit tests had methods
294 which have been removed from the Node class they're mocking,
295 there's no need to shadow those any more as there are no callers.
296 The methods are depends_on (base functionality removed in 2005)
297 and is_pseudeo_derived (base functionality removed in 2006). There
299 - Added pass_test() call to test/MSVC/MSVC_BATCH-spaces-targetdir.py.
300 It looked it was missing a more detailed check, but it should be
301 sufficient just to check the build worked. Renamed the fixture
302 dir to follow naming convention in test/MSVC overall, and added
303 a sconstest.skip file, also to follow convention.
304 - Marked some scanner methods as @staticmethod.
305 - Class ActionBase is now an abstract base class to more accurately
306 reflect its usage. Derived _ActionAction inherits the ABC, so it
307 now declares (actually raises NotImplementedError) two methods it
308 doesn't use so it can be instantiated by unittests and others.
309 - The yacc tool now understands the bison behavior of --header,
310 --defines and --graph being called without option-argument as being
311 synonyms for -d (first two) and -g. -H also recognized as a synonym
312 for -d. Default value for $YACC_GRAPH_FILE_SUFFIX changed to '.gv'
313 to match current bison default (since bison 3.8). Set this variable
314 to '.dot' if using byacc. The graph file name (-g) is now generated
315 relative to the requested target file name, not to the source file
316 name, to match actual current behavior (only affects if target
317 explicitly requested with a different base name
318 than source). Docs updated. Fixes #4326 and #4327.
319 - Cleaned up dblite module (checker warnings, etc.).
320 - Some cleanup in the FortranCommon tool.
321 - Rewrite the internal _subproc routine - a new scons_subproc_run() now
322 makes use of Python's subprocess.run in a more natural way, getting
323 around some of the issues with attempted context manager use, fetching
324 output, etc. - we let the subprocess module do the hard work,
325 since it's well debugged and supported. _subproc is no longer
326 called by internal code, but remains in place in case there are builds
327 which call to it (even though it was never "published API").
328 - Changed the message about scons -H to clarify it shows built-in options.
329 - Improve CacheDir() Documentation.
330 - Release-building setup tweaked. (most of) the targets listed in
331 SCons' own "scons --help" now work again.
332 - Fix platform unit test on Windows for Py 3.12+. Fixes #4376.
333 - More tweaking of test framework overview (which is duplicated onto
334 the website, but not in the regular documentation section).
335 - Extend range of recognized Java versions to 20.
336 - Builder calls now accept PathLike objects in source lists. Fixes #4398.
337 - The Help() function now takes an additional keyword argument
338 keep_local: when starting to build a help message, you can now
339 retain help from AddOption calls, but omit help for SCons' own
340 command-line options with "Help(newtext, append=True, local_only=True)".
341 - A little more code "modernization", done via "pypgrade" tool set
342 to "3.6 and above" setting.
343 - Finish the change to make calling SConscript() with a nonexistent
344 file an error. It has issued a warning since 3.0, with "warn instead
345 of fail" deprecated since 3.1. Fixes #3958.
346 - Minor (non-functional) cleanup of some tests, particuarly test/MSVC.
347 - Added more error handling while reading msvc config cache.
348 (Enabled/specified by SCONS_CACHE_MSVC_CONFIG).
349 The existing cache will be discarded if there's a decode error reading it.
350 It's possible there's a race condition creating this issue in certain CI
351 builds. Also add a simple filesystem-based locking protocol to try to
352 avoid the problem occuring.
353 - Update the first two chapters on building with SCons in the User Guide.
354 - Update docs on Export/Import - make sure mutable/immutable status has
356 - Some cleanup to the Util package, including renaming SCons.Util.types
357 to SCons.Util.sctypes to avoid any possible confusion with the
358 Python stdlib types module.
359 - TeX tests: skip tests that use makeindex or epstopdf not installed, or
360 if `kpsewhich glossaries.sty` fails.
361 - Added a .note.GNU-stack section to the test assembler files to
362 avoid the GNU linker issuing warnings for its absence.
363 - Eliminate more http: references (mostly in comments/docstrings where
364 they really weren't harmful). A few links labeled dead with no alt.
365 - Add JDK 21 LTS support
366 - Add a LIBLITERALPREFIX variable which can be set to the linker's
367 prefix for considering a library argument unmodified (e.g. for the
368 GNU linker, the ':' in '-l:libfoo.a'). Fixes Github issue #3951.
369 - Update PCH builder docs with some usage notes.
371 RELEASE 4.5.2 - Sun, 21 Mar 2023 14:08:29 -0700
374 - Remove the redundant `wheel` dependency from `pyproject.toml`,
375 as it is added automatically by the setuptools PEP517 backend.
378 - Fix a problem (#4321) in 4.5.0/4.5.1 where ParseConfig could cause an
379 exception in MergeFlags when the result would be to add preprocessor
380 defines to existing CPPDEFINES. The following code illustrates the
381 circumstances that could trigger this:
382 env=Environment(CPPDEFINES=['a'])
383 env.Append(CPPDEFINES=['b'])
384 env.MergeFlags({'CPPDEFINES': 'c'})
387 RELEASE 4.5.1 - Mon, 06 Mar 2023 14:08:29 -0700
390 - Fix a problem in 4.5.0 where using something like the following code
391 will cause a Clone()'d environment to share the CPPDEFINES with the
392 original Environment() which was cloned. Causing leakage of changes
393 to CPPDEFINES when they should be completely independent after the Clone.
394 env=Environment(CPPDEFINES=['a'])
395 env.Append(CPPDEFINES=['b']) (or AppendUnique,Prepend,PrependUnique)
397 env1.Append(CPPDEFINES=['c']) (or any other modification, but not overwriting CPPDEFINES
398 Now env['CPPDEFINES'] will contain 'c' when it should not.
401 RELEASE 4.5.0 - Sun, 05 Mar 2023 14:08:29 -0700
403 From Anatoli Babenia:
404 - Do not initialize DefaultEnvironment when calling EnsureSConsVersion(),
405 EnsurePythonVersion(), Exit(), GetLaunchDir() and SConscriptChdir().
406 - Remove unused private method SConsEnvironment._exceeds_version().
409 - Added ValidateOptions() which will check that all command line options are in either
410 those specified by SCons itself, or by AddOption() in SConstruct/SConscript. It should
411 not be called until all AddOption() calls are completed. Resolves Issue #4187
412 - Refactored SCons/Taskmaster into a package. Moved SCons/Jobs.py into that package.
413 NOTE: If you hook into SCons.Jobs, you'll have to change that to use SCons.Taskmaster.Jobs
414 - Changed the Taskmaster trace logic to use python's logging module. The output formatting
415 should remain (mostly) the same. Minor update to unittest for this to adjust for 1 less newline.
416 - Migrated logging logic for --taskmastertrace to use Python's logging module. Added logging
417 to NewParallel Job class (Andrew Morrow's new parallel job implementation)
418 - Ninja: Fix execution environment sanitation for launching ninja. Previously if you set an
419 execution environment variable set to a python list it would crash. Now it
420 will create a string joining the list with os.pathsep
421 - Move execution environment sanitation from Action._subproc() to
422 SCons.Util.sanitize_shell_env(ENV)
423 - Moved rpm and debian directories under packaging
424 - Added logic to help packagers enable reproducible builds into packaging/etc/. Please
425 read packaging/etc/README.txt if you are interested.
426 - Added --experimental=tm_v2, which enables Andrew Morrow's new NewParallel Job implementation.
427 This should scale much better for highly parallel builds. You can also enable this via SetOption().
428 - Fixed command line argument --diskcheck: previously a value of 'none' was ignored.
429 SetOption('diskcheck','none') is unaffected, as it did not have the problem.
430 - Added overrides argument to SCons.Subst.scons_subst(), subst_list(), subst(), and Action's process(),
431 strfunction(). This allows passing a dictionary of envvars to override when evaluating subst()'d strings/lists
432 - Fixed Issue #4275 - when outputting compilation db and TEMPFILE was in use, the compilation db would have
433 command lines using the generated tempfile for long command lines, instead of the full command line for
434 the compilation step for the source/target pair.
435 - Renamed the qt tools to qt3 since the logic in that tool is only for QT version 3. Renamed all env vars
436 which affect qt3 from QT_ to QT3_. If you are still using SCons to build QT 3 code, you'll need to update
437 your SConscripts. Note that using 'qt' tool has been deprecated for some time.
440 - Added JAVAPROCESSORPATH construction variable which populates -processorpath.
441 - Updated JavaScanner to scan JAVAPROCESSORPATH.
443 From Nickolai Korshunov
444 - Added FILE_ENCODING, to allow explicitly setting the text encoding for files
445 written by the Textfile() and Substfile() builders. If not specified, Textfile() and Substfile() builders
446 will write files as UTF-8. Fixed Issue #4302.
448 From Dan Mezhiborsky:
449 - Add newline to end of compilation db (compile_commands.json).
452 - Added error message to handle the case when SCons attempts to retrieve all the targets
453 for a specified builder from the CacheDir, fails to do so, and then runs into an error
454 when deleting the files which were retrieved. Previously if this happened there was no
456 - Fix issue #2757, where Configure checks that perform a check which reads a modified source
457 (including program, source or header file(s)) would incorrectly mark that file "up to date" so the
458 actual build would not see the file as modified. Leading to incorrect incremental builds.
459 Now configure checks now clear node info for non conftest nodes, so they will be re-evaluated for
460 the real taskmaster run when the build commences.
463 - Avoid returning UniqueList for `children` and other `Executor` APIs. This type
464 iterates more slowly than the builtin types. Also simplify uniquer_hashables to
465 use an faster implementation under the assumption of ordered dictionaries.
468 - Fixed runtest.py failure on Windows caused by excessive escaping of the path to python.exe.
471 - Run LaTeX after biber/bibtex only if necessary
474 - Added -fsanitize support to ParseFlags(). This will propagate to CCFLAGS and LINKFLAGS.
477 - A list argument as the source to the Copy() action function is now
478 correctly handled by converting elements to string. Copy errors out
479 if asked to copy a list to an existing non-directory destination.
480 Both the implementation and the strfunction which prints the progress
481 message were adjusted. Fixes #3009.
482 - doc: EnsureSConsVersion, EnsurePythonVersion, Exit, GetLaunchDir and
483 SConscriptChdir are now listed as Global functions only; the
484 Environment versions still work but are not documented.
485 - The Java scanner processing of JAVACLASSPATH for dependencies was
486 changed to split on os.pathsep instead of space, to match usage of
487 passing a path string like "xxx:yyy:zzz". This is not portable -
488 passing a POSIX-style path string (with ':') won't work on Windows
489 (';') - which is now documented with a hint to use a list instead
490 to be portable. Splitting on space broke paths with embedded spaces.
492 - Cleanup: make sure BoolVariable usage in tests and examples uses Python
493 boolean values instead of 0/1.
494 - Stop telling people to run "python setup.py install" in the User Guide.
495 Adds new content on using virtualenvs to be able to have multiple
496 different SCons versions available on one system.
497 - Added the "DefaultEnvironment(tools=[])" stanza to a number of tests
498 that are known to be particularly slow. It's still just a tiny
499 speedup, but the Windows CI had been occasionally timing out,
500 so maybe this helps a bit.
501 - Remove an extra existence check in one ninja test that caused it
502 to be skipped on some otherwise-valid Windows installations.
503 - test framework tests now pass on Linux and Windows (the latter can
504 still run into problems on some configurations), and automated
505 tests are now run on changes in this area so future problems can
507 - The single-file Util module was split into a package with a few
508 functional areas getting their own files - Util.py had grown to
510 - Add a zipapp package of scons-local: can use SCons from a local
511 file which does not need unpacking.
512 - Additional explanations for MSVSProject and MSVSSolution builders.
513 - Fix a problem (present in 4.4.0 only) where a Java inner class could
514 not be cached because the emitted filename contained a '$' and when
515 looked up through a node ended up generating a Python SyntaxError
516 because it was passed through scons_subst().
517 - Have the gfortran tool do a better job of honoring user preferences
518 for the dialect tools (F77, F90, F03 and F09, as well as the shared-library
519 equivalents SHF77, SHF90, SHF03, SHF09). Previously these were
520 unconditionally overwritten to 'gfortran'; the change should be more
521 in line with expectations of how these variables should work.
522 Also cleaned a few Fortran tests - test behavior does not change.
523 - Updated MSVC documentation - adds "version added" annotations on recently
524 added construction variables and provides a version-mapping table.
525 - Add Python 3.12 support, and indicate 3.11/3.12 support in package.
526 3.12 is in alpha for this SCons release, the bytecode sequences
527 embedded in SCons/ActionTests.py may need to change later, but
528 based on what is known now, 3.12 itself should work with this release.
529 - Add "append" keyword argument to Configure context's CheckLib and
530 CheckLibWithHeader to control whether to append or prepend (issue #2767)
531 Also added "unique" keyword, to control whether a library is added
532 or not if it is already in the $LIBS construction var in the
533 configure context. (issue #2768).
534 - Completely refactored the CPPDEFINES logic in Append/AppendUnique/Prepend/PrependUnique
535 This change fixes the following GH Issues:
536 - GH Issue #3876 - Append() and AppendUnique() will handle CPPDEFINES the same
537 - GH Issue #4254 - Make handling tuples in CPPDEFINES consistent.
538 - We no longer sort the keys added to CPPDEFINES by their dictionary keys.
539 We take advantage that their order is now stable based on insertion order
541 - Added/modifed unit and system tests to verify these changes.
544 RELEASE 4.4.0 - Sat, 30 Jul 2022 14:08:29 -0700
547 - Verify that a user specified msvc script (via MSVC_USE_SCRIPT) exists and raise an exception
548 when the user specified msvc script does not exist.
549 - Fix issue where if you only had mingw installed on a Windows system and no MSVC compiler, and
550 did not explicitly request the mingw tool, mingw tool initialization would fail and set the
551 default compiler to MSVC which wasn't installed, yielding broken build.
552 Updated mingw tool so that the generate and exists methods use the same mingw search paths
554 - Update the debug output written to stdout for MSVC initialization which is enabled by setting
555 SCONS_MSCOMMON_DEBUG=- to use the logging module. Also changed the debug output format
556 written to stdout to include more information about the source for each message of MSVC
557 initialization debugging output. A single space was added before the message for all
558 debugging output records written to stdout and to files.
559 - Refactor the data definitions for msvc configurations to allow derived data structures to be
560 constructed during initialization that removes the need for special case handling during
561 runtime execution. Special case handling of host/target combinations is eliminated and
562 replaced with pre-computed search lists that implicitly handle the differences between full
563 versions and express versions of msvc. This fixes an issue where Express versions of the MSVC
564 compiler were not detected due to differences in initial msvc detection and msvc batch file
565 determination when configuring the build environment. This could lead to build failures when
566 only an MSVC Express instance is installed and the MSVC version is not explicitly specified
567 (issue #2668 and issue #2697).
568 - Added MSVC_USE_SETTINGS construction variable to pass a dictionary to configure the msvc compiler
569 system environment as an alternative to bypassing Visual Studio autodetection entirely.
570 - Added MSVC_SDK_VERSION construction variable which allows building with a specific Microsoft
571 SDK version. This variable is used with the msvc batch file determined via autodetection subject
572 to validation constraints. Refer to the documentation for additional requirements and validation
574 - Added MSVC_TOOLSET_VERSION construction variable which allows building with a specific toolset
575 version. This variable is used with the msvc batch file determined via autodetection subject to
576 validation constraints. This variable does not affect the autodetection and selection of msvc
577 instances. The toolset version is applied after an msvc instance is selected. This could be the
578 default version of msvc. Refer to the documentation for additional requirements and validation
579 details. Addresses issue #3265, issue #3664, and pull request #4149.
580 - Added MSVC_SPECTRE_LIBS construction variable which allows building with spectre-mitigated
581 Visual C++ libraries. This variable is used with the msvc batch file determined via autodetection
582 subject to validation constraints. Refer to the documentation for additional requirements and
584 - Added MSVC_SCRIPT_ARGS construction variable which specifies command line arguments that are
585 passed to the msvc batch file determined via autodetection subject to validation constraints.
586 Refer to the documentation for additional requirements and validation details. Addresses
587 enhancement issue #4106.
588 - An exception is raised when MSVC_UWP_APP is enabled for Visual Studio 2013 and earlier.
589 Previous behavior was to silently ignore MSVC_UWP_APP when enabled for Visual Studio 2013
590 and earlier. Refer to the documentation for additional requirements and validation details.
591 MSVC_UWP_APP was extended to accept True, False, and None in addition to '1' and '0'.
592 - The imported system environment variable names for MSVC 7.0 and 6.0 have been changed to the
593 names set by their respective installers. Prior to this change, bypassing MSVC detection by
594 specifying the MSVC 7.0 batch file directly would fail due to using an erroneous environment
595 variable name. Arguments are no longer passed to the MSVC 6.0 to 7.1 batch files as no
596 arguments are required and could improve the effectiveness of the internal MSVC cache.
597 - Propagate the OS and windir environment variables from the system environment to the msvc
598 environment. The OS and windir environment variables are used in the MSVC 6.0 batch file
599 and the SDK 6.0-7.1 SetEnv.cmd batch files. Inclusion of the OS and windir environment
600 variables eliminates some partial paths and warnings generated by the MSVC 6.0 and SDK
601 6.0-7.1 batch files when the variables are not defined.
602 Note: Attempting to run the SDK 6.0-7.1 batch files directly via MSVC_USE_SCRIPT can lead to
603 build failures and/or incomplete build environments. The SDK 6.0-7.1 batch files
604 require delayed expansion to be enabled which is currently not supported and is
605 typically not enabled by default on the host system. The batch files may also require
606 environment variables that are not included by default in the msvc environment.
607 - Suppress issuing a warning when there are no installed Visual Studio instances for the default
608 tools configuration (issue #2813). When msvc is the default compiler because there are no
609 compilers installed, a build may fail due to the cl.exe command not being recognized. At
610 present, there is no easy way to detect during msvc initialization if the default environment
611 will be used later to build a program and/or library. There is no error/warning issued for the
612 default tools as there are legitimate SCons uses that do not require a c compiler.
613 - Added a global policy setting and an environment construction variable for specifying the
614 action to be taken when an msvc request cannot be satisfied. The available options are "error",
615 "exception", "warning", "warn", "ignore", and "suppress". The global policy variable may be
616 set and retrieved via the functions msvc_set_notfound_policy and msvc_get_notfound_policy,
617 respectively. These two methods may be imported from SCons.Tool.MSCommon. The environment
618 construction variable is MSVC_NOTFOUND_POLICY. When defined, the environment construction
619 variable overrides the global policy setting for a given environment. When the active policy
620 is "error" or "exception", an MSVCVersionNotFound exception is raised. When the active policy
621 is "warning" or "warn", a VisualCMissingWarning warning is issued and the constructed
622 environment is likely incomplete. When the active policy is "ignore" or "suppress", no action
623 is taken and the constructed environment is likely incomplete. As implemented, the default
624 global policy is "warning". The ability to set the global policy via an SCons command-line
625 option may be added in a future enhancement.
626 - Added a global policy setting and an environment construction variable for specifying the
627 action to be taken when msvc script errors are detected. The available options are "error",
628 "exception", "warning", "warn", "ignore", and "suppress". The global policy variable may be
629 set and retrieved via the functions msvc_set_scripterror_policy and msvc_get_scripterror_policy,
630 respectively. These two methods may be imported from SCons.Tool.MSCommon. The environment
631 construction variable is MSVC_SCRIPTERROR_POLICY. When defined, the environment construction
632 variable overrides the global policy setting for a given environment. When the active policy
633 is "error" or "exception", an MSVCScriptExecutionError exception is raised when msvc batch file
634 errors are detected. When the active policy is "warning" or "warn", an MSVCScriptExecutionWarning
635 warning is issued when msvc batch file errors are detected. When the active policy is "ignore" or
636 "suppress", msvc batch error messages are suppressed. As implemented, the default global policy
637 is "ignore". The ability to set the global policy via an SCons command-line option may be added
638 in a future enhancement.
639 - Added experimental function msvc_query_version_toolset to SCons.Tool.MSCommon. Given a version
640 specification, this function will return an msvc version and an msvc toolset version. The msvc
641 toolset version may be None. The msvc version and msvc toolset version can be used in the
642 environment construction variables MSVC_VERSION and MSVC_TOOLSET_VERSION, respectively. The
643 version specification may be an msvc version or an msvc toolset version. This is a proxy for
644 using an msvc toolset version to select an msvc instance. This function may be removed when an
645 msvc toolset version is used during msvc instance selection.
646 - Modify the MSCommon logger configuration to be independent of the root logger. This fixes an issue
647 when multiple loggers are created and the MSCommon logger added computed fields to the root logger
648 that are not present in other logging instances.
649 - Modify the MSVC_USE_SCRIPT_ARGS test fixture to disable the msvc cache. This fixes an issue where
650 the MSVC_USE_SCRIPT_ARGS test for success relied on a debug log message that was not produced when
651 the msvc cache file exists and the test keys are already in the cache as the msvc script invocation
655 - Fix check for unsupported Python version. It was broken. Also now the error message
656 will include what is the minimum supported version of Python
657 - Fix ActionTests to work with python 3.10.1 (and higher)
658 NOTE: If you build with Python 3.10.0 and then rebuild with 3.10.1 (or higher), you may
659 see unexpected rebuilds. This is due to Python internals changing which changed
660 the signature of a Python Action Function.
661 - Fix a number of Python ResourceWarnings which are issued when running SCons and/or it's tests
662 with python 3.9 (or higher)
663 - Action._subproc() can now be used as a python context manager to ensure that the
664 POpen object is properly closed.
665 (Thanks to Mats Wichmann for catching that DummyPopen needed additional logic)
666 - Added project_url for mailing lists and Discord
667 - Updated project url in steup.cfg to be https instead of http
668 - Updated setup.cfg to remove Python 3.5 and add Python 3.10
669 - Added default values for source and target arguments to _defines() function. This
670 is used to expand CPPDEFINES (and others). Previous change added those arguments
671 with no defaults, so old usage where _defines() was called without source and target
672 arguments would yield an exception. This issue was found via qt4 and qt5 tools in
673 scons-contrib https://github.com/SCons/scons-contrib/issues/45
676 - Add JavaScanner to include JAVACLASSPATH as a dependency when using the Java tool.
677 - Fix incorrect Java classpath generation when a NodeList is used as part of any JAVA*PATH variables.
680 - Add cache-debug messages for push failures.
681 - Ninja: Changed generated build.ninja file to run SCons only build Actions via
682 a SCons Deamon. Added logic for starting and connecting to SCons daemon (currently
684 - Ninja: Fix issue where Configure files weren't being properly processed when build run
686 - Ninja: Added ninja mingw support and improved ninja CommandGeneratorAction support.
687 - Ninja: Update ninja file generation to only create response files for build commands
688 which exceed MAXLINELENGTH
689 - Ninja: Added NINJA_GENERATED_SOURCE_ALIAS_NAME which allows user to specify an
690 Alias() which the ninja tool can use to determine which files are generated sources.
691 If this is not set by the user then the ninja tool will still dynamically determine
692 which files are generated sources based on NINJA_GENERATED_SOURCE_SUFFIXES, and create
693 a phony target _ninja_generated_sources. Generated sources will be built first by
694 ninja. This is needed because ninja cannot determine which generated sources are
695 required by other build targets. Code contributed by MongoDB
696 The downstream commit is here:
697 https://github.com/mongodb/mongo/commit/2fef432fa6e7cf3fd4f22ba3b193222c2887f14f
698 - Ninja: Added special case for ninja scons daemon to work in win32 python3.6 environments.
699 This particular environment does a bad job managing popen standard file handles, so
700 some special workarounds are needed.
701 - Ninja:Added user configurable setting of ninja depfile format via NINJA_DEPFILE_PARSE_FORMAT.
702 Now setting NINJA_DEPFILE_PARSE_FORMAT to [msvc,gcc,clang] can force the ninja expected
703 format. Compiler tools will also configure the variable automatically.
704 - Ninja: Made ninja tool force the ninja file as the only target.
705 - Ninja: Improved the default targets setup and made sure there is always a default target for
706 the ninja file, which excludes targets that start and stop the daemon.
707 - Ninja: Update ninja tool so targets passed to SCons are propagated to ninja when scons
708 automatically executes ninja.
709 - Small refactor of scons daemons using a shared StateInfo class for communication
710 between the scons interactive thread and the http server thread. Added error handling
711 for scons interactive failing to startup.
712 - Ninja: Updated ninja scons daemon scripts to output errors to stderr as well as the daemon log.
713 - Ninja: Fix typo in ninja scons daemon startup which causes ConnectionRefusedError to not retry
714 - Added SHELL_ENV_GENERATORS construction variable. This variable should be set to a list
715 (or an iterable) which contains functions to be called in order
716 when constructing the execution environment (Generally this is the shell environment
717 variables). This allows the user to customize how (for example) PATH is constructed.
718 Note that these are called for every build command run by SCons. It could have considerable
719 performance impact if not used carefully.
720 to connect to the server during start up.
721 - lex: Fixed an issue with the lex tool where file arguments specified to either "--header-file="
722 or "--tables-file=" which included a space in the path to the file would be processed incorrectly
723 - Ninja: added option "--skip-ninja-regen" to enable skipping regeneration of the ninja file
724 if scons can determine the ninja file doesnot need to be regenerated, which will also
725 skip restarting the scons daemon. Note this option is could result in incorrect rebuilds
726 if scons Glob or scons generated files are used in ninja build target's command lines.
727 - Ninja: Added new alias "shutdown-ninja-scons-daemon" to allow ninja to shutdown the daemon.
728 Also added cleanup to test framework to kill ninja scons daemons and clean ip daemon logs.
729 NOTE: Test for this requires python psutil module. It will be skipped if not present.
730 - Ninja: Added command line variable NINJA_CMD_ARGS that allows to pass through ninja command line args.
731 This can also be set in your Environment().
734 - Tweak the way default site_scons paths on Windows are expressed to
735 conform to conventions (what they actually resolve to is unchanged),
736 drop a Py2 workaround, and pick a better "system" path, old one
737 remains supported (%AllUsersProfile%\scons\site_scons vs old
738 %AllUsersProfile%\Application Data\scons\site_scons).
739 - Fix testsuite to work on Windows systems where there is no usable
740 association for running .py files directly. There are a few tests where
741 we need to do this for internal reasons, those are skipped in that case.
742 Bad association could mean some other tool took it over (Visual
743 Studio Code is known to do this), or no association at all.
744 - Updated debug code in MSVC and MSVS tools to conform to the
745 suggested "lazy interpolation" use of the Python logging module.
746 Calls now look like 'debug("template %s", text)' rather than
747 'debug("template %s" % text)' so the logging system does the
748 interpolation only when/if needed (was a pylint warning).
749 - Update Help (-H) output a bit. Drop "ignored for compat" entry.
750 Pass window size to formatter so it formats for wider displays too.
751 - runtest.py now accepts -j 0 to auto-detect number of usable
752 processors for testing threads.
753 - Fixed crash in C scanner's dictify_CPPDEFINES() function which happens if
754 AppendUnique is called on CPPPATH. (Issue #4108).
755 - The MSVC script_env_cache now contains a sanity check: if the retrieved
756 tools path does not exist, the entry is invalidated so it will
757 be recomputed, in an attempt to avoid scons failing when certain
758 compiler version bumps have taken place. The dictionary key (uses
759 the name of a batch file and any arguments which may have been
760 passes), is now computed a bit differently: the dashes are left
761 off if there are no arguments. The default cachefile is changed
762 to have a .json suffix, for better recognition on Windows since
763 the contents are json.
764 - As "code modernization" all of SCons now uses the current super()
765 zero-argument syntax instead of direct calls to a parent class method
766 or the super() two-argument syntax.
767 - Renamed ParseFlag's internal data structure to "mapping" instead of
768 "dict" (avoid redefining builtin)
769 - Fix an old use-before-set bug in tex tool (issue #2888)
770 - Fix a test harness exception returning stderr if a wait_for timed out.
771 - ParseConfig now correctly passes the *unique* flag to a user-supplied
772 flag-merging function.
773 - Restore the ability of the content-timestamp decider to see that a
774 a source which is a symlink has changed if the file-system target of
775 that link has been modified (issue #3880)
776 - Modernize a few tests that use now-deprecated unittest.getTestCaseNames
777 and unittest.makeSuite - Python itself suggests the replacements.
778 - SCons.Tool.find_program_path now takes an optional add_path argument
779 to add a path to the execution environment if it was discovered in
780 default_paths. Previously, the routine, called by many tool modules,
781 never altered the execution environment, leaving it to the tools.
782 - A new construction variable FORTRANCOMMONFLAGS is added which is
783 applied to all Fortran dialects, in case someone needs to set some
784 flags globally. FORTRANFLAGS looked like it was intended for that,
785 but was not applied to other dialects, and e2e tests explicitly checked
786 that FORTRANFLAGS did not propagate outside the FORTRAN dialect,
787 so the conclusion is that behavior is intentional (issue #2257)
788 - SCons programmatic importing (tool modules and platform modules)
789 no longer uses the deprecated (since Py 3.10) importlib.load_module
790 routine, shifting to the preferred exec_module. Old Python 2 compatible
791 import fallback (using the imp module) in tool module loading is dropped.
792 Tool module loading no longer special-cases Jython, which is a dead
793 project as far as SCons (no timeline in sight for Python 3 support).
794 - Improvements to lex and yacc tools: better documentation of
795 extra-file options, add test for extra-file behavior.
796 - Two new construction variables are introduced for lex (LEX_HEADER_FILE
797 and LEX_TABLES_FILE) as the preferred way of specifying these extra-file
799 - Two new construction variables are introduced for yacc
800 (YACC_HEADER_FILE and YACC_GRAPH_FILE) as the preferred way of
801 specifying these extra-file options.
805 - Added MSVC_USE_SCRIPT_ARGS variable to pass arguments to MSVC_USE_SCRIPT.
806 - Added Configure.CheckMember() checker to check if struct/class has the specified member.
808 From Ivan Kravets, PlatformIO:
809 - Conditional C/C++ Preprocessor: Strip shell's backslashes from the computed include (-DFOO_H=\"foo.h\")
811 RELEASE 4.3.0 - Tue, 16 Nov 2021 18:12:46 -0700
813 From Jacob Cassagnol:
814 - Default hash algorithm check updated for SCons FIPS compliance. Now checks for hash viability
815 first and then walks the tree to use the first viable hash as the default one. This typically
816 selects SHA1 on FIPS-enabled systems less than Python 3.9 as the new default instead of MD5,
817 unless SHA1 has also been disabled by security policy, at which point SCons selects SHA256
818 as the default. For systems running Python 3.9 and later, the hashlib bug has been fixed,
819 and SCons will once again default to MD5 as the preferred algorithm.
822 - Fix MSVS tests (vs-N.N-exec.py) for MSVS 6.0, 7.0, and 7.1 (import missing module).
823 - Add support for Visual Studio 2022.
826 - Fix reproducible builds. Restore logic respecting SOURCE_DATE_EPOCH when set.
827 - Fix version tests to work with updated scons --version output. (Date format changed)
828 - Fix issue #4021. Change the way subst() is used in Textfile() to not evaluate '$$(' -> '$',
829 but instead it should yield '$('.
830 - Change SCons.Platform.win32.get_architecture() to return platform.platform() when run in an
831 environment where neither: PROCESSOR_ARCHITEW6432 nor PROCESSOR_ARCHITECTURE is set.
832 This should fix platform tests which started failing when HOST_OS/HOST_ARCH changes
833 introduced by Aaron Franke (listed below) were merged.
834 - Further PCH updates. It's now recommended that env['PCH'] should always be a File node.
835 Either via return value from env.PCH() or by explicitly using File('StdAfx.pch').
836 - Added --no-ignore-skips to runtest.py. Changed default to ignore skips when setting
837 runtest.py's exit status. Previously would exit 2 if any tests were skipped.
838 Now will only exit 2 if user specifies --no-ignore-skips and some tests were skipped.
841 - Small fix to ensure CLVar default value is an empty list.
842 See MongoDB bug report: https://jira.mongodb.org/browse/SERVER-59656
843 Code contributed by MongoDB.
844 - Ninja - Fixed an issue where if you control-c and/or killed ninja while it was running scons to
845 regenerate build.ninja you would end up with no build.ninja file and have to rerun scons from scratch.
846 Code contributed by MongoDB.
849 - Define HOST_OS and HOST_ARCH in the environment for all platforms.
850 Before this change, these were only defined for Win32 and OS/2.
853 - Fix ninja tool to never use for_sig substitution because ninja does not use signatures. This
854 issue affected CommandGeneratorAction function actions specifically.
855 - Expanded ninja Mkdir to also support Mkdir actions.
856 - Added support for the PCH environment variable to support subst generators.
857 - Fix command line escaping for ninja dollar sign escape. Without escaping ninja properly,
858 the ninja file scons regenerate and callback invocations will lose the $ characters used in
859 the scons command line which ninja uses itself for escaping. For Example:
860 scons BUILD=xyz OTHERVAR=$BUILD
861 Prior to this fix, it would cause ninja to fail to escape the dollar sign, leading to the
862 single dollar sign being used as a ninja escape character in the ninja file.
865 - Added ninja API 'NINJA_FORCE_SCONS_BUILD' to force a node to callback to scons.
868 - Two small Python 3.10 fixes: one more docstring turned into raw
869 because it contained an escape; updated "helpful" syntax error message
870 from 3.10 was not expected by SubstTests.py and test/Subst/Syntax.py
871 - EmitterProxy rich comparison set is completed (checker warning).
872 Added __le__, __gt__, __ge__.
873 - Fix gcc/g++ tool failing if "gcc --version" returns text which fails
874 to_String conversion (i.e., not UTF-8) - failure happens when tool
875 initialization checks version. For gcc, the initial version string is
876 not translated, for the rest, don't convert, just consume raw and discard.
877 - Maintenance and doc: modernize some usage in Scanner package,
878 calling super(), switching some imitialization to comprehensions,
879 and code formatting. Docstring for scanner Base moved from
880 init-method to class-level so it's picked up by Sphinx.
881 Added new sconsign filenames to skip_entry_list in Scanner/Dir.py
882 - Change SCons.Scanner.Base to ScannerBase. Old name kept as an alias
883 but is now unused in SCons itself.
884 - Call Variables option converter consistently - the converter should
885 have access to the env if it needs to (issue #2064).
886 - Fixed the variables Add() method to accept a tuple for the variable
887 name the same way AddVariables() does (issue #3869).
888 - The premade validator PathIsDirCreate for for PathVariable now catches
889 the case where the directory could not be created due to permission
890 problems, allowing a more helpful error to be emitted (issue #2828)
891 - Maintenance: Python thread.setDaemon is deprecated in favor of
892 directly updating daemon attribute - update SCons to do this.
893 - Make sure when subst'ing a callable, the callable is called with
894 the correct for_signature value, previously it would be true even
895 if doing SUBST_RAW (issue #4037)
896 - Update Util/NodeList implementation to get rid of a workaround for
897 early Python 3 slicing issue that is no longer a problem.
898 - Rework some Java tests to skip rather than fail on CI systems, where
899 the working java is > v9, but a 1.8 or 9 was also found.
900 - Java updates: on Windows, detect more default JDK install locations.
901 On all platforms, more Java versions (up to 17.0 now). Add more information
902 on version selection to docs.
903 Update docs on JavaH tool in light of javah command dropped since 10.0.
904 Try to be better about preserving user's passed-in JAVA* construction vars.
905 - Start the deprecation of the qt tool, which refers to Qt3 (usupported
906 since around 2006). There's a deprecation warning added, initially
907 defaulting to disabled.
909 From Brian Quistorff:
910 - Fix crash when scons is run from a python environement where a signal
911 is set from outside Python.
914 RELEASE 4.2.0 - Sat, 31 Jul 2021 18:12:46 -0700
917 - Fix Install() issue when copytree recursion gives bad arguments that can
918 lead to install side-effects including keeping dangling symlinks and
919 silently failing to copy directories (and their subdirectories) when the
920 directory already exists in the target.
923 - Internal MSVS update: Remove unnecessary calls to find all installed versions of msvc
924 when constructing the installed visual studios list.
927 - Improve Subst()'s logic to check for proper callable function or class's argument list.
928 It will now allow callables with expected args, and any extra args as long as they
929 have default arguments. Additionally functions with no defaults for extra arguments
930 as long as they are set using functools.partial to create a new callable which set them.
931 - Fix Issue #3035 - mingw with SHLIBVERSION set fails with either not a dll error or
932 "Multiple ways to build the same target were specified for:". Now mingw will disable
933 creating the symlinks (and adding version string to ) dlls. It sets SHLIBNOVERSIONSYMLINKS,
934 IMPLIBNOVERSIONSYMLINKS and LDMODULENOVERSIONSYMLINKS to True.
935 - Added --experimental flag, to enable various experimental features/tools. You can specify
936 'all', 'none', or any combination of available experimental features.
937 - Fix Issue #3933 - Remove unguarded print of debug information in SharedLibrary logic when
938 SHLIBVERSION is specified.
939 - Fix versioned shared library naming for MacOS platform. (Previously was libxyz.dylib.1.2.3,
940 has been fixed to libxyz.1.2.3.dylib. Additionally the sonamed symlink had the same issue,
941 that is now resolved as well)
942 - Add experimental ninja builder. (Contributed by MongoDB, Daniel Moody and many others).
943 - Fix #3955 - _LIBDIRFLAGS leaving $( and $) in *COMSTR output. Added affect_signature flag to
944 _concat function. If set to False, it will prepend and append $( and $). That way the various
945 Environment variables can use that rather than "$( _concat(...) $)".
946 - Fix issue with exparimental ninja tool which would fail on windows or when ninja package wasn't
947 installed but --experimental=ninja was specified.
948 - As part of experimental ninja tool, allow SetOption() to set both disable_execute_ninja and
952 - Fix Issue #3906 - `IMPLICIT_COMMAND_DEPENDENCIES` was not properly disabled when
953 set to any string value (For example ['none','false','no','off'])
954 Also previously 'All' wouldn't have the desired affect.
957 - Provide a custom argument escape function for `TempFileMunge` using a new
958 `TEMPFILEARGESCFUNC` variable. Useful if you need to apply extra operations on
959 a command argument before writing to a temporary file (fix Windows slashes,
960 normalize paths, etc.)
963 - DocbookXslt tool: The XSLT stylesheet file is now initialized to an env.File() Node,
964 such that dependencies work correctly in hierarchical builds (eg when using
965 DocbookXslt in SConscript('subdir/SConscript') context.
968 - Update CacheDir to use uuid for tmpfile uniqueness instead of pid.
969 This fixes cases for shared cache where two systems write to the same
970 cache tmpfile at the same time because the happened to get the same pid.
971 - Added support for passing custom CacheDir derived classes to SCons. Moved
972 copy_from_cache attribute from the Environment class to CacheDir class.
973 Code contributed by MongoDB.
974 - Update BuildTask to pass all targets to the progress object fixing an issue
975 where multi-target build nodes only got the first target passed to the progress
977 - Fix a potential race condition in shared cache environments where the permissions are
978 not writeable for a moment after the file has been renamed and other builds (users) will copy
979 it out of the cache. Small reorganization of logic to copy files from cachedir. Moved CacheDir
980 writeable permission code for copy to cache behind the atomic rename operation.
981 - Added marking of intermediate and and multi target nodes generated from SConf tests so that
982 is_conftest() is more accurate.
983 - Added test for configure check failing to ensure it didn't break generating and running ninja.
987 - Initial support in tests for Python 3.10 - expected bytecode and
988 one changed expected exception message. Change some more regexes
989 to be specified as rawstrings in response to DeprecationWarnings.
990 - Add an example of adding an emitter to User Guide (concept
992 - Add timing information for sconsign database dump when --debug=time
993 is selected. Also switch to generally using time.perf_counter,
994 which is the Python recommended way for timing short durations.
995 - Drop remaining definitions of dict-like has_key methods, since
996 Python 3 doesn't have a dictionary has_key (maintenance)
997 - Do not treat --site-dir=DIR and --no-site-dir as distinct options.
998 Allows a later instance to override an earlier one.
999 - Ignore empty cmdline arguments when computing targets (issue 2986)
1000 - Remove long-deprecated construction variables PDFCOM, WIN32_INSERT_DEF,
1001 WIN32DEFPREFIX, WIN32DEFSUFFIX, WIN32EXPPREFIX, WIN32EXPSUFFIX.
1002 All have been replaced by other names since at least 1.0.
1003 - Add a __iadd__ method to the CLVar class so that inplace adds
1004 (+=) also work as expected (issue 2399)
1005 - Remove local copy of CLVar in EnvironmentTests unittest file -
1006 should be testing against the production version, and they
1007 didn't really differ.
1008 - Don't strip spaces in INSTALLSTR by using raw subst (issue 2018)
1009 - Deprecate Python 3.5 as a supported version.
1010 - CPPDEFINES now expands construction variable references (issue 2363)
1011 - Restore behavior that Install()'d files are writable (issue 3927)
1012 - Simplified Mkdir(), the internal mkdir_func no longer needs to handle
1013 existing directories, it can now pass exist_ok=True to os.makedirs().
1014 - Avoid WhereIs exception if user set a tool name to empty (from issue 1742)
1015 - Maintenance: remove obsolete __getslice__ definitions (Py3 never calls);
1016 add Node.fs.scandir to call new (Py3.5) os.scandir; Node.fs.makedirs
1017 now passes the exist_ok flag; Cachedir creation now uses this flag.
1018 - Maintenance: remove unneeded imports and reorganize some. Fix uses
1019 of warnings in some tools which instantiated the class but did nothing
1020 with them, need to instead call SCons.Warnings.warn with the warn class.
1021 - Drop overridden changed_since_last_build method in Value class.
1022 - Resync the SetOption implementation and the manpage, making sure new
1023 options are available and adding a notes column for misc information.
1024 SetOption equivalents to --hash-chunksize, --implicit-deps-unchanged
1025 and --implicit-deps-changed are enabled.
1026 - Add tests for SetOption failing on disallowed options and value types.
1027 - Maintenance: eliminate lots of checker complaints about Util.py.
1028 - Maintenance: fix checker-spotted issues in Environment (apply_tools)
1029 and EnvironmentTests (asserts comparing with self).
1030 For consistency, env.Tool() now returns a tool object the same way
1032 - Change SConscript() missing SConscript behavior - if must_exist=False,
1033 the warning is suppressed.
1034 - Make sure TEMPFILEPREFIX can be set to an empty string (issue 3964)
1037 - Add support for the (TARGET,SOURCE,TARGETS,SOURCES,CHANGED_TARGETS,CHANGED_SOURCES}.relpath property.
1038 This will provide a path relative to the top of the build tree (where the SConstruct is located)
1042 - Fix issue #3790: Generators in CPPDEFINES now have access to populated source
1045 RELEASE 4.1.0 - Tues, 19 Jan 2021 15:04:42 -0700
1048 - Add COMPILATIONDB_PATH_FILTER env option for CompilationDatabase() builder which allows
1049 filtering of entries based on the output file paths using glob style file matching (issue #3742).
1052 - Internal MSVC and test updates: Rework the msvc installed versions cache so that it
1053 is not exposed externally and update external references accordingly.
1054 - Modify the MSCommon internal-use only debug logging records to contain the correct relative
1055 file path when the debug function is called from outside the MSCommon module.
1057 From William Deegan:
1058 - Fix yacc tool, not respecting YACC set at time of tool initialization.
1059 - Refactor SCons.Tool to move all common shared and loadable module linking logic to SCons.Tool.linkCommon
1060 - Remove pywin32 imports from SCons.Script.Main. No longer needed.
1061 - Switch to use ctypes instead of pywin32 (requiring an extra pip install) - Fixes Github Issue #2291
1062 - pywin32 no longer necessary for SCons install. (pip install SCons will no longer also require pywin32 on win32)
1063 - Remove pywin32 usage from SCons.Util where it was used for accessing the registry. Python native winreg
1064 library already includes this functionality.
1065 - Remove using pywin32 to retrieve peak memory usage on Win32 for `--debug=memory`
1066 - Fix Issue #3759 - include scons.1, sconsign.1, scons-time.1 manpages in sdist and wheel packages.
1067 - Change SCons's build so the generated `SCons/__init__.py` is no longer removed by `scons -c`
1068 - Completely rewrote versioned shared libraries logic. Added support for SOVERSION via dmoody's initial PR #3733
1069 - No longer automatically disable setting SONAME on shared libraries on OpenBSD.
1070 - Fix race condition bug when initializing a scons cache directory at the
1071 same time from multiple threads or processes. Problem described in PR #3114.
1072 This is a simpler fix which should avoid some problems identified with the initial PR.
1073 (Credit to Fredrik Medley for reporting the issue, the initial PR, and discussing and testing
1075 - Minor edits to User Guide and manpage's header with copyright, released date changed.
1078 - Fix dvipdf test failure due to passing incorrect flag to dvipdf.
1081 - Fix minor bug affecting SCons.Node.FS.File.get_csig()'s usage of the MD5 chunksize.
1082 User-facing behavior does not change with this fix (GH Issue #3726).
1083 - Fix occasional test failures caused by not being able to find a file or directory fixture
1084 when running multiple tests with multiple jobs.
1085 - Added support for a new command-line parameter `--hash-format` to override the default
1086 hash format that SCons uses. It can also be set via `SetOption('hash_format')`. Supported
1087 values are: `md5`, `sha1`, and `sha256`. For all hash formats other than
1088 the default of `md5`, the SConsign database will include the name of the hash format.
1089 For example, `--hash-format=sha256` will create a SConsign with name
1090 `.sconsign_sha256.dblite.`.
1091 - Fix incorrect cache hits and/or misses when running in interactive mode by having
1092 SCons.Node.Node.clear() clear out all caching-related state.
1093 - Change Environment.SideEffect() to not add duplicate side effects.
1094 NOTE: The list of returned side effect Nodes will not include any duplicate side effect Nodes.
1095 - Add support to the Python scanner for finding dynamically generated dependencies.
1096 Previously the scanner only found imports if they existed on disk at scanning time.
1099 - Add ZIP_OVERRIDE_TIMESTAMP env option to Zip builder which allows for overriding of the file
1100 modification times in the archive.
1101 - Fix Zip builder not rebuilding when ZIPROOT env option was changed.
1104 - Fix python3 crash when Value node get_text_content when child content does not have decode()
1105 NOTE: If you depend on Value node's get_text_content returning concatenated contents of it's
1106 children. This may break your code. It now concatenates the csig() of all children.
1108 From Joachim Kuebart:
1109 - Suppress missing SConscript deprecation warning if `must_exist=False`
1113 - Fix Zip tool to respect ZIPCOMSTR. Previously all zip builder calls would yield something
1114 like zip(["test.zip"], ["zip_scons.py"]) and ignore ZIPCOMSTR if ZIPCOM and ZIPCOMSTR
1115 weren't set after the Environment/Tool is initialized. (Explained in PR #3659)
1118 - Fix issue where java parsed a class incorrectly from lambdas used after a new.
1121 - Fix using TEMPFILE in multiple actions in an action list. Previously a builder, or command
1122 with an action list like this:
1123 ['${TEMPFILE("xxx.py -otempfile $SOURCE")}', '${TEMPFILE("yyy.py -o$TARGET tempfile")}']
1124 Could yield a single tempfile with the first TEMPFILE's contents, used by both steps
1128 - Complete tests for Dictionary, env.keys() and env.values() for
1129 OverrideEnvironment. Enable env.setdefault() method, add tests.
1130 - Raise an error if an option (not otherwise consumed) is used which
1131 looks like an abbreviation of one one added by AddOption. (#3653)
1132 - Tool module not found will now raise a UserError to more clearly indicate this is
1133 probably an SConscript problem, and to make the traceback more relevant.
1134 - Fix three issues with MergeFlags:
1135 - Signature/return did not match documentation or existing usage - the implementation
1136 now no longer returns the passed env
1137 - merging --param arguments did not work (issue #3107);
1138 - passing a dict to merge where the values are strings failed (issue #2961).
1139 - Include previously-excluded SideEffect section in User Guide.
1140 - Clean up unneeded imports (autoflake tool).
1141 - Make sure cProfile is used if profiling - SCons was expecting
1142 the Util module to monkeypatch in cProfile as profile if available,
1143 but this is no longer being done.
1144 - Cleanup in SCons.Util.AddMethod. If called with an environment instance
1145 as the object to modify, the method would not be correctly set up in
1146 any Clone of that instance. Now tries to detect this and calls
1147 MethodWrapper to set up the method the same way env.AddMethod does.
1148 MethodWrapper moved to Util to avoid a circular import. Fixes #3028.
1149 - Some Python 2 compatibility code dropped
1150 - Rework runtest.py to use argparse for arg handling (was a mix
1151 of hand-coded and optparse, with a stated intent to "gradually port").
1152 - Add options to runtest to generate/not generate a log of failed tests,
1153 and to rerun such tests. Useful when an error cascades through several
1154 tests, can quickly try if a change improves all the fails. Dropped
1155 runtest test for fallback from qmtest, not needed; added new tests.
1156 - Eliminate tex tool usage of "for foo in range(len(iterable))"
1157 - Restore internal Trace function to functional state.
1158 - Only try to initialize the wix tool by default (or when tool `default` is explicitly installed)
1159 on Windows based systems.
1160 - Pick a better "Topic" Trove classifier for SCons: SW Dev / Build Tools
1161 - Use os.replace instead of os.rename in dblite so don't need to
1162 special-case Windows here. dblite is the default storage engine for the SConsign file(s).
1163 - Fix cut-n-paste error in msvc debug printout and make some debug output
1164 in msvs and msvsTests.py be off until needed (uncomment to use)
1165 - Fix Issue #3014 - Empty file and missing file have same csig
1166 - Refactor env.Append/Prepend to remove Py 1.5 era need to nest
1167 try blocks, can now "continue" at the appropriate places.
1168 - Add /snap/bin to env['PATH'] on POSIX, although this is only
1169 really useful for a subset of POSIX systems that use snaps.
1170 Was needed for CI builds, which run on Ubuntu LTS images.
1171 - Eliminate Py2-ism __nonzero__ (now __bool__). Work around issue #3860
1172 where a check for BuilderBase raising exc. on __bool__ was optimized out.
1173 This issue was found due to a bug in Python 3.10.0a4. See issue #3860 for details.
1176 RELEASE 4.0.1 - Mon, 16 Jul 2020 16:06:40 -0700
1179 - Fix fortran tools to set SHFORTRAN variables to $FORTRAN, similarly SHF77, SHF90, SHF95,
1180 SHF03 and SHF08 will default to the variables $F77, $F90, $F95, $F03 and $F08 respectively.
1181 If you were depending on changing the value of FORTRAN (or $F[0-9][0-9]) having no effect
1182 on the value of SHFORTRAN, this change will break that. The values of FORTRAN, F77, F90,
1183 F95, F03, F08 and SHFORTRAN, SHF77 (etc.) now are not overridden in generate if alredy set
1185 - Fix subprocess execution of 'lslpp' on AIX to produce text standard i/o.
1186 - Re-do the fix for suncxx tool (Oracle Studio compiler) now that only Python 3 is supported,
1187 to avoid decoding errors.
1189 From William Deegan:
1190 - Added Environment() variable TEMPFILEDIR which allows setting the directory which temp
1191 files createdby TEMPFILEMUNGE are created in.
1194 - Added method on Node to test if its node used in SConf. (Github Issue #3626)
1198 RELEASE 4.0.0 - Sat, 04 Jul 2020 12:00:27 +0000
1201 - Updated documentation toolchain to work properly under Python3, also
1202 removed libxslt support from the Docbook Tool. (issue #3580)
1203 - Added Docker images for building and testing SCons. (issue #3585)
1207 - Improve Visual Studio solution/project generation code to add support
1208 for a per-variant cppflags. Intellisense can be affected by cppflags,
1209 this is especially important when it comes to /std:c++* which specifies
1210 what C++ standard version to target. SCons will append /Zc:__cplusplus
1211 to the project's cppflags when a /std:c++* flag is found as this is
1212 required for intellisense to use the C++ standard version from cppflags.
1215 - Specify UTF-8 encoding when opening Java source file as text. By default, encoding is the output
1216 of locale.getpreferredencoding(False), and varies by platform.
1219 - MSVC updates: When there are multiple product installations (e.g, Community and
1220 Build Tools) of MSVC 2017 or MSVC 2019, an Enterprise, Professional,
1221 or Community installation will be selected before a Build Tools installation when
1222 "14.1" or "14.2" is requested, respectively. (GH Issue #3699).
1223 - MSVC updates: When there are multiple product installations of MSVC 2017 (e.g.,
1224 Community and Express), 2017 Express is no longer returned when "14.1" is
1225 requested. Only 2017 Express will be returned when "14.1Exp" is requested.
1227 - MSVC updates: An MSVC 6.0 installation now appears in the installed versions list
1228 when msvc debug output is enabled (GH Issue #3699).
1229 - MSVS test updates: Tests for building a program using generated MSVS project and
1230 solution files using MSVS 2015 and later now work as expected on x86 hosts.
1231 - Test update: Reduce the number of "false negative" test failures for the interactive
1232 configuration test (test/interactive/configure.py).
1233 - MSVS update: Fix the development environment path for MSVS 7.0.
1235 From William Deegan:
1236 - Fix broken clang + MSVC 2019 combination by using MSVC configuration logic to
1237 propagate'VCINSTALLDIR' and 'VCToolsInstallDir' which clang tools use to locate
1238 header files and libraries from MSVC install. (Fixes GH Issue #3480)
1239 - Added C:\msys64\mingw64\bin to default mingw and clang windows PATH's. This
1240 is a reasonable default and also aligns with changes in Appveyor's VS2019 image.
1241 - Drop support for Python 2.7. SCons will be Python 3.5+ going forward.
1242 - Change SCons.Node.ValueWithMemo to consider any name passed when memoizing Value() nodes
1243 - Fix Github Issue #3550 - When using Substfile() with a value like Z:\mongo\build\install\bin
1244 the implementation using re.sub() would end up interpreting the string and finding regex escape
1245 characters where it should have been simply replacing existing text. Switched to use string.replace().
1246 - Fix Github Issue #2904 - Provide useful error message when more than one Configure Contexts are opened.
1247 Only one open is allowed. You must call conf.Finish() to complete the currently open one before creating another
1248 - Add msys2 installed mingw default path to PATH for mingw tool.
1249 - C:\msys64\mingw64\bin
1250 - Purge obsolete internal build and tooling scripts
1251 - Allow user specified location for vswhere.exe specified by VSWHERE.
1252 NOTE: This must be set at the time the 'msvc' 'msvs' and/or 'mslink' tool(s) are initialized to have any effect.
1253 - Resolve Issue #3451 and Issue #3450 - Rewrite SCons setup.py and packaging. Move script logic to entry points so
1254 package can create scripts which use the correct version of Python.
1255 - Resolve Issue #3248 - Removing '-Wl,-Bsymbolic' from SHLIBVERSIONFLAGS
1256 NOTE: If your build depends on the above you must now add to your SHLIBVERSIONFLAGS
1257 - Speedup bin/docs-update-generated by caching parsed docbook schema. (60x speedup)
1258 - Reorganized source tree. Moved src/engine/SCons to SCons to be more in line with current Python source
1259 tree organization practices.
1260 - Renamed as.py to asm.py and left redirecting tool. 'as' is a reserved word and so
1261 changing the name was required as we wanted to import symbols for use in compilation_db
1263 - Add CompilationDatabase() builder in compilation_db tool. Contributed by MongoDB.
1264 Setting COMPILATIONDB_USE_ABSPATH to True|False controls whether the files are absolute or relative
1265 paths. Address Issue #3693 and #3694 found during development.
1266 - Fixed Github Issue 3628 - Hardcoding pickle protocol to 4 (supports python 3.4+)
1267 and skipping Python 3.8's new pickle protocol 5 whose main advantage is for out-of-band data buffers.
1268 NOTE: If you used Python 3.8 with SCons 3.0.0 or above, you may get a a pickle protocol error. Remove your
1269 .sconsign.dblite. You will end up with a full rebuild.
1271 From Andrii Doroshenko:
1272 - Extended `Environment.Dump()` to select a format to serialize construction variables (pretty, json).
1275 - Updated design doc to use the correct syntax for Depends()
1278 - Added support for scanning multiple entries in an action string if
1279 IMPLICIT_COMMAND_DEPENDENCIES is set to 2 or 'all'. This enables more thorough
1280 action scanning where every item in each command line is scanned to determine
1281 if it is a non-source and non-target path and added to the list of implicit dependencies
1283 - Added support for taking instances of the Value class as implicit
1285 - Added new module SCons.Scanner.Python to allow scanning .py files.
1286 - Added support for explicitly passing a name when creating Value() nodes. This may be useful
1287 when the value can't be converted to a string or if having a name is otherwise desirable.
1288 - Fixed usage of abspath and path for RootDir objects on Windows. Previously
1289 env.fs.Dir("T:").abspath would return "T:\T:" and now it correctly returns "T:".
1291 From Ivan Kravets, PlatformIO
1292 - New conditional C Scanner (`SCons.Scanner.C.CConditionalScanner()`)
1293 which interprets C/C Preprocessor conditional syntax (#ifdef, #if, #else,
1294 #elif, #define, etc.)
1295 - Improvements for virtual C Pre-Processor:
1296 * Handle UNSIGNED LONG and LONG numeric constants in DEC (keep support for HEX)
1297 * Skip unrecognized directives, such as `#if( defined ...)`
1298 * Ignore `#include DYNAMIC_INCLUDE` directive that depends on a dynamic
1299 macro which is not located in a state TABLE.
1300 * Cleanup CPP expressions before evaluating (strip comments, carriage returns)
1303 - Added a new flag called "linedraw" for the command line argument "--tree"
1304 that instructs scons to use single line drawing characters to draw the dependency tree.
1307 - Add no_progress (-Q) option as a set-able option. However, setting it in the
1308 SConstruct/SConscript will still cause "scons: Reading SConscript files ..." to be
1309 printed, since the option is not set when the build scripts first get read.
1310 - Added check for SONAME in environment to setup symlinks correctly (Github Issue #3246)
1311 - User callable's called during substition expansion could possibly throw a TypeError
1312 exception, however SCons was using TypeError to detect if the callable had a different
1313 signature than expected, and would silently fail to report user's exceptions. Fixed to
1314 use signature module to detect function signature instead of TypeError. (Github Issue #3654)
1315 - Added storage of SConstructs and SConscripts nodes into global set for checking
1316 if a given node is a SConstruct/SConscript.
1317 Added new node function SCons.Node.is_sconscript(self) (Github Issue #3625)
1320 - Fix Issue #3469 - Fixed improper reuse of temporary and compiled files by Configure when changing
1321 the order and/or number of tests. This is done by using the hash of the generated temporary files
1322 content and (For the target files) the hash of the action.
1323 So where previously files would be named:
1324 - config_1.c, config_1.o, config_1
1325 The will now be named (For example)
1326 - conftest_68b375d16e812c43e6d72d6e93401e7c_0.c,
1327 conftest_68b375d16e812c43e6d72d6e93401e7c_0_5713f09fc605f46b2ab2f7950455f187.o
1329 conftest_68b375d16e812c43e6d72d6e93401e7c_0.o
1330 conftest_68b375d16e812c43e6d72d6e93401e7c_0_5713f09fc605f46b2ab2f7950455f187 (for executable)
1332 From Mathew Robinson:
1333 - Improve performance of Subst by preventing unnecessary frame
1334 allocations by no longer defining the *Subber classes inside of their
1335 respective function calls.
1336 - Improve performance of Subst in some cases by preventing
1337 unnecessary calls to eval when a token is surrounded in braces
1338 but is not a function call.
1339 - Improve performance of subst by removing unnecessary recursion.
1340 - Cleanup dangling symlinks before running builders (Issue #3516)
1343 - Remove deprecated SourceCode
1344 - str.format syntax errors fixed
1345 - a bunch of linter/checker syntax fixups
1346 - Convert remaining uses of insecure/deprecated mktemp method.
1347 - Clean up some duplications in manpage. Clarify portion of manpage on Dir and File nodes.
1348 - Reduce needless list conversions.
1349 - Fixed regex in Python scanner.
1350 - Accommodate VS 2017 Express - it's got a more liberal license then VS
1351 Community, so some people prefer it (from 2019, no more Express)
1352 - vswhere call should also now work even if programs aren't on the C: drive.
1353 - Add an alternate warning message if cl.exe is not found and msvc config
1354 cache is in use (SCONS_CACHE_MSVC_CONFIG was given) - config cache
1356 - Fixed bug where changing TEXTFILESUFFIX would cause Substfile() to rebuild. (Github Issue #3540)
1357 - Script/Main.py now uses importlib instead of imp module.
1358 - Drop some Python 2-isms.
1359 - MSVC updates: pass on VSCMD_DEBUG and VSCMD_SKIP_SENDTELEMETRY to msvc
1360 tool setup if set in environment. Add Powershell to default env
1361 (used to call telemetry script).
1362 - Microsoft Visual Studio - switch to using uuid module to generate GUIDs rather than hand rolled
1363 method using md5 directly.
1364 NOTE: This change affects the following builders' output. If your build depends on the output of these builders
1365 you will likely see a rebuild.
1366 * Package() (with PACKAGETYPE='msi')
1369 - Docbook builder provides a fallback if lxml fails to generate
1370 a document with tostring().
1371 - Fix description of ARCOMSTR constr. var. (issue 3636). Previously the text was a copy of ASCOMSTR which
1372 has different function.
1373 - Update xml files in SCons to reflect changed relative paths after
1374 code restructuring (src/engine/SCons -> SCons)
1375 - Preliminary Python 3.9 support - elimination of some warnings.
1376 - Drop the with_metaclass jig which was designed to let class
1377 definitions using a metaclass be written the same for Py2/Py3.
1378 - Bump python_version_unsupported (and deprecated) to indicate 3.5
1379 is lowest supported Python.
1380 - ParseFlags should not modify the user's passed in dict in case it's
1381 a compound data structure (e.g. values are lists) (issue #3665)
1382 - In Py3 classes no longer need to be listed as deriving from object.
1383 - Remove deprecated check for Task subclasses needing a needs_execute
1384 method - this is now enforced via an abstract base class, so the
1385 check and test is no longer needed.
1386 - Close various logfiles (trace, cache, taskmastertrace, configure)
1387 when done using atexit calls.
1388 - Rebase forked copy of shutil.copytree to Python 3.7 stlib version.
1389 - Significant rework of documentation: API docs are now generated
1390 using Sphinx; manpage and user guide now use more "standard"
1391 markup elements (which could facilitate later conversion to a
1392 different doc format, should that choice be made); significant
1393 rewordings in manpage. Manpage Examples moved to an external
1394 repository / website (scons-cookbook.readthedocs.io).
1395 - Clean up test harness and tests' use of subdir, file_fixture and
1397 - SubstitutionEnvironment and OverrideEnvironment now have keys()
1398 and values() methods to better emulate a dict (already had items()).
1399 - Rename internal Warning base class to SConsWarning to avoid any
1400 possible confusion with Python's own Warning class.
1403 RELEASE 3.1.2 - Mon, 17 Dec 2019 02:06:27 +0000
1405 From Edoardo Bezzeccheri
1406 - Added debug option "action_timestamps" which outputs to stdout the absolute start and end time for each target.
1409 - Fix suncxx tool (Oracle Studio compiler) when using Python 3. Previously would throw an exception.
1410 Resolved by properly handling tool version string output as unicode.
1413 - Resolved a typo in engine.SCons.Tool
1416 - Resolved a race condition in multithreaded Windows builds with Python 2
1417 in the case where a child process is spawned while a Python action has a
1418 file open. Original author: Ryan Beasley.
1419 - Added memoization support for calls to Environment.Value() in order to
1420 improve performance of repeated calls.
1424 - Update Command() function to accept target_scanner, source_factory, and target_factory arguments.
1425 This makes Command act more like a one-off builder.
1428 - Added support for "-imacros" to ParseFlags
1431 - Fix CheckFunc detection code for Visual 2019. Some functions
1432 (e.g. memmove) were incorrectly recognized as not available.
1435 - Fix stacktrace when using SCons with Python 3.5+ and SunOS/Solaris related tools.
1437 From Philipp Maierhöfer:
1438 - Avoid crash with UnicodeDecodeError on Python 3 when a Latex log file in
1439 non-UTF-8 encoding (e.g. containing umlauts in Latin-1 encoding when
1440 the fontenc package is included with \usepackage[T1]{fontenc}) is read.
1442 From Mathew Robinson:
1443 - Improved threading performance by ensuring NodeInfo is shared
1444 across threads. Results in ~13% improvement for parallel builds
1445 (-j# > 1) with many shared nodes.
1446 - Improve performance of Entry.disambiguate() by making check for
1447 most common case first, preventing unnecessary IO.
1448 - Improved DAG walk performance by reducing unnecessary work when
1449 there are no un-visited children.
1452 - Replace instances of string find method with "in" checks where
1453 the index from find() was not used.
1454 - CmdStringHolder fix from issue #3428
1455 - Turn previously deprecated debug options into failures:
1456 --debug=tree, --debug=dtree, --debug=stree, --debug=nomemoizer.
1457 - Experimental New Feature: Enable caching MSVC configuration
1458 If SCONS_CACHE_MSVC_CONFIG shell environment variable is set,
1459 SCons will cache the results of past calls to vcvarsall.bat to
1460 a file; integrates with existing memoizing of such vars.
1461 On vs2019 saves 5+ seconds per SCons invocation, which really
1462 helps test suite runs.
1463 - Remove deprecated SourceSignatures, TargetSignatures
1464 - Remove deprecated Builder keywords: overrides and scanner
1465 - Remove deprecated env.Copy
1466 - Remove deprecated BuildDir plus SConscript keyword build_dir
1467 - A number of documentation improvements.
1470 RELEASE 3.1.1 - Mon, 07 Aug 2019 20:09:12 -0500
1472 From William Deegan:
1473 - Remove obsoleted references to DeciderNeedsNode which could cause crash when using --debug=explain
1476 - Add Fix and test for crash in 3.1.0 when using Decider('MD5-timestamp') and --debug=explain
1479 - Added -fmerge-all-constants to flags that get included in both CCFLAGS and LINKFLAGS.
1481 From Mathew Robinson:
1482 - Fix issue #3415 - Update remaining usages of EnvironmentError to SConsEnvironmentError
1483 this patch fixes issues introduced in 3.1.0 where any of the
1484 following would cause SCons to error and exit:
1485 - CacheDir not write-able
1486 - JSON encoding errors for CacheDir config
1487 - JSON decoding errors for CacheDir config
1489 RELEASE 3.1.0 - Mon, 20 Jul 2019 16:59:23 -0700
1492 - Code to supply correct version-specifier argument to vswhere for
1493 VS version selection.
1495 From William Deegan:
1496 - Enhanced --debug=explain output. Now the separate components of the dependency list are split up
1499 scons: rebuilding `file3' because:
1500 the dependency order changed:
1507 Old:/usr/bin/python New:/usr/bin/python
1508 - Fix Issue #3350 - SCons Exception EnvironmentError is conflicting with Python's EnvironmentError.
1509 - Fix spurious rebuilds on second build for cases where builder has > 1 target and the source file
1510 is generated. This was causing the > 1th target to not have it's implicit list cleared when the source
1511 file was actually built, leaving an implicit list similar to follows for 2nd and higher target
1512 ['/usr/bin/python', 'xxx', 'yyy', 'zzz']
1513 This was getting persisted to SConsign and on rebuild it would be corrected to be similar to this
1514 ['zzz', 'yyy', 'xxx', '/usr/bin/python']
1515 Which would trigger a rebuild because the order changed.
1516 The fix involved added logic to mark all shared targets as peers and then ensure they're implicit
1517 list is all cleared together.
1518 - Fix Issue #3349 - SCons Exception EnvironmentError is conflicting with Python's EnvironmentError.
1519 Renamed to SConsEnvironmentError
1520 - Fix Issue #3350 - mslink failing when too many objects. This is resolved by adding TEMPFILEARGJOIN variable
1521 which specifies what character to join all the argements output into the tempfile. The default remains a space
1522 when mslink, msvc, or mslib tools are loaded they change the TEMPFILEARGJOIN to be a line separator (\r\n on win32)
1523 - Fix performance degradation for MD5-timestamp decider. NOTE: This changes the Decider() function arguments.
1525 def my_decider(dependency, target, prev_ni):
1527 def my_decider(dependency, target, prev_ni, repo_node):
1528 Where repo_node is the repository (or other) node to use to check if the node is out of date instead of dependency.
1531 - Additional fix to issue #3135 - Also handle 'pure' and 'elemental' type bound procedures
1532 - Fix issue #3135 - Handle Fortran submodules and type bound procedures
1535 - Upgraded and improved Visual Studio solution/project generation code using the MSVSProject builder.
1536 - Added support for Visual Studio 2017 and 2019.
1537 - Added support for the following per-variant parameters to the builder:
1538 - cpppaths: Provides per-variant include paths.
1539 - cppdefines: Provides per-variant preprocessor definitions.
1541 From Michael Hartmann:
1542 - Fix handling of Visual Studio Compilers to properly reject any unknown HOST_PLATFORM or TARGET_PLATFORM
1545 - Added support for Visual Studio 2019 toolset.
1547 From Mathew Robinson:
1548 - Update cache debug output to include cache hit rate.
1549 - No longer unintentionally hide exceptions in Action.py
1550 - Allow builders and pseudo-builders to inherit from OverrideEnvironments
1552 From Leonard de Ruijter:
1553 - Add logic to derive correct version argument to vswhere
1555 From Lukas Schrangl:
1556 - Enable LaTeX scanner to find more than one include per line
1558 From Sergey Torokhov:
1559 - Recognize jdk on Gentoo systems.
1562 - scons-time takes more care closing files and uses safer mkdtemp to avoid
1563 possible races on multi-job runs.
1564 - Use importlib to dynamically load tool and platform modules instead of imp module
1565 - sconsign: default to .sconsign.dblite if no filename is specified.
1566 Be more informative in case of unsupported pickle protocol (py2 only).
1567 - Fix issue #3336 - on Windows, paths were being added to PATH even if
1568 tools were not found in those paths.
1569 - More fixes for newer Java versions (since 9): handle new jdk directory
1570 naming (jdk-X.Y instead of jdkX.Y) on Windows; handle two-digit major
1571 version. Docstrings improved.
1572 - Fixups for pylint: exception types, redefined functions,
1573 globals, etc. Some old code removed to resolve issues (hashlib is
1574 always present on modern Pythons; no longer need the code for
1575 2.5-and-earlier optparse). cmp is not a builtin function in Py3,
1576 drop one (unused) use; replace one. Fix another instance of
1577 renaming to SConsEnvironmentError. Trailing whitespace.
1578 Consistently use not is/in (if not x is y -> if x is not y).
1579 - Add a PY3-only function for setting up the cachedir that should be less
1580 prone to races. Add a hack to the PY2 version (from Issue #3351) to
1581 be less prone to a race in the check for old-style cache.
1582 - Fix coding error in docbook tool only exercised when using python lxml
1583 - Recognize two additional GNU compiler header directory options in
1584 ParseFlags: -iquote and -idirafter.
1585 - Fix more re patterns that contain \ but not specified as raw strings
1586 (affects scanners for D, LaTeX, swig)
1589 RELEASE 3.0.5 - Mon, 26 Mar 2019 15:04:42 -0700
1591 From William Deegan:
1593 - Fix Issue #3283 - Handle using --config=force in combination with Decider('MD5-timestamp').
1594 3.0.2 in fix for issue #2980 added that deciders can throw DeciderNeedsNode exception.
1595 The Configure logic directly calls the decider when using --config=force but wasn't handling
1596 that exception. This would yield minimally configure tests using TryLink() not running and
1597 leaving TypeError Nonetype exception in config.log
1598 - Fix Issue #3303 - Handle --config=force overwriting the Environment passed into Configure()'s
1599 Decider and not clearing it when the configure context is completed.
1600 - Add default paths for yacc tool on windows to include cygwin, mingw, and chocolatey
1601 - Fix issue #2799 - Fix mingw tool to respect SHCCCOMSTR, SHLINKCOMSTR and LDMODULECOMSTR
1602 - Fix Issue #3329 - Add support for MS SDK V10.0A (which is commonly installed with VS2017)
1603 - Fix Issue #3333 - Add support for finding vswhere under 32 bit windows installs.
1605 From Maciej Kumorek:
1606 - Update the MSVC tool to include the nologo flag by default in RCFLAGS
1609 - Change the default for AppendENVPath to delete_existing=0, so path
1610 order will not be changed, unless explicitly set (Issue #3276)
1611 - Fixed bug which threw error when running SCons on windows system with no MSVC installed.
1612 - Update link tool to convert target to node before accessing node member
1613 - Update mingw tool to remove MSVC like nologo CCFLAG
1614 - Add default paths for lex tool on windows to include cygwin, mingw, and chocolatey
1615 - Add lex construction variable LEXUNISTD for turning off unix headers on windows
1616 - Update lex tool to use win_flex on windows if available
1619 - Quiet open file ResourceWarnings on Python >= 3.6 caused by
1620 not using a context manager around Popen.stdout
1621 - Add the textfile tool to the default tool list
1622 - Fix syntax on is/is not clauses: should not use with a literal
1623 - Properly retrieve exit code when catching SystemExit
1624 - scons-time now uses context managers around file opens
1625 - Fix regex patterns that were not specified as raw strings
1627 From Bernhard M. Wiedemann:
1628 - Do not store build host+user name if reproducible builds are wanted
1631 RELEASE 3.0.4 - Mon, 20 Jan 2019 22:49:27 +0000
1634 - Improve finding of Microsoft compiler: add a 'products' wildcard
1635 in case 2017 Build Tools only is installed as it is considered a separate
1636 product from the default Visual Studio
1637 - Add TEMPFILESUFFIX to allow a customizable filename extension, as
1638 described in the patch attached to issue #2431.
1639 - scons.py and sconsign.py stopped working if script called as a symlink
1640 to location in scons-local location.
1641 - Fix issue running scons using a symlink to scons.py in an scons-local dir
1642 - Doc updates around Default(), and the various *TARGETS variables.
1645 - Improved support for VC14.1 and Visual Studio 2017, as well as arm and arm64 targets.
1646 Issues #3268 & Issue #3222
1647 - Initial support for ARM targets with Visual Studio 2017 - Issue #3182 (You must set TARGET_ARCH for this to work)
1648 - Update TempFileMunge class to use PRINT_CMD_LINE_FUNC
1651 - Enhance cpp scanner regex logic to detect if/elif expressions without whitespaces but
1652 parenthesis like "#if(defined FOO)" or "#elif!(BAR)" correctly.
1655 RELEASE 3.0.3 - Mon, 07 Jan 2019 20:05:22 -0400
1656 NOTE: 3.0.2 release was dropped because there was a packaging bug. Please consider all 3.0.2
1659 From William Deegan:
1660 - Fixes to packaging logic. Ensuring the SCons.Tool.clangCommon module is added
1661 to the release packages.
1662 - Modify scons.bat script to check for scons python script without .py extension if no file
1663 scons.py exists. This enables an all platform wheel to work.
1666 - Update doc examples to work with Python 3.5+: map() now returns an iterable instead of a list.
1669 RELEASE 3.0.2 - Mon, 31 Dec 2018 16:00:12 -0700
1671 From Bernard Blackham:
1672 - Fixed handling of side-effects in task master (fixes #3013).
1674 From William Deegan:
1675 - Remove long deprecated SCons.Options code and tests. This removes BoolOption,EnumOption,
1676 ListOption,PackageOption, and PathOption which have been replaced by *Variable() many years ago.
1677 - Re-Enable parallel SCons (-j) when running via Pypy
1678 - Move SCons test framework files to testing/framework and remove all references to QMtest.
1679 QMTest has not been used by SCons for some time now.
1680 - Updated logic for mingw and clang on win32 to search default tool install paths if not
1681 found in normal SCons PATH. If the user specifies PATH or tool specific paths they
1682 will be used and the default paths below will be ignored.
1683 - Default path for clang/clangxx : C:\Program Files\LLVM\bin
1684 - Default path for mingw : C:\MinGW\bin and/or C:\mingw-w64\*\mingw64\bin
1685 - Key program to locate mingw : mingw32-make (as the gcc with mingw prefix has no fixed name)
1686 - Fixed issue causing stack trace when python Action function contains a unicode string when being
1688 - Add alternate path to QT install for Centos in qt tool: /usr/lib64/qt-3.3/bin
1689 - Fix Java tools to search reasonable default paths for Win32, Linux, macOS. Add required paths
1690 for swig and java native interface to JAVAINCLUDES. You should add these to your CPPPATH if you need
1691 to compile with them. This handles spaces in paths in default Java paths on windows.
1692 - Added more java paths to match install for Centos 7 of openjdk
1693 - Fix new logic which populates JAVAINCLUDES to handle the case where javac is not found.
1694 - Fix GH Issue #2580 - # in FRAMEWORKPATH doesn't get properly expanded. The # is left in the
1696 - Fix issue #2980 with credit to Piotr Bartosik (and William Blevins). This is an issue where using
1697 TimeStamp-MD5 Decider and CacheDir can yield incorrect md5's being written into the .sconsign.
1698 The difference between Piotr Bartosik's patch and the current code is that the more complicated
1699 creation of file to csig map is only done when the count of children for the current node doesn't
1700 match the previous count which is loaded from the sconsign.
1701 - Fix issue # 3106 MSVC if using MSVC_BATCH and target dir had a space would fail due to quirk in
1702 MSVC's handling of escaped targetdirs when batch compiling.
1703 - Fix GH Issue #3141 unicode string in a TryAction() with python 2.7 crashes.
1704 - Fix GH Issue #3212 - Use of Py3 and CacheDir + Configure's TryCompile (or likely and Python Value Nodes)
1705 yielded trying to combine strings and bytes which threw exception.
1706 - Fix GH Issue #3225 SCons.Util.Flatten() doesn't handle MappingView's produced by dictionary as return
1707 values from dict().{items(), keys(), values()}.
1708 - Fix GH Issue #3241 - Properly support versioned shared libraries for MacOS. We've also introduced two
1709 new env variables APPLELINK_CURRENT_VERSION and APPLELINK_COMPATIBILITY_VERSION which will specify
1710 what is passed to the linkers -current_version and -compatibility_version flags. If not specified
1711 they will be derived from SHLIBVERSION as such:
1712 - APPLELINK_CURRENT_VERSION = SHLIBVERSION
1713 - APPLELINK_COMPATIBILITY_VERSION = all but the last digit in SHLIBVERSION with .0 appended.
1714 Note that the values of the above will be validated. Valid format for either APPLELINK variable is
1715 X[.Y[.Z]] where 0 <= X <= 65535, 0 <= Y <= 255, 0 <= Z <= 255.
1716 The new variables have been added to the documents and should show up in user guide and manpage.
1717 - Fix GH Issue #3136 no longer wrap io.{BufferedReader,BufferedWriter,BufferedRWPair,BufferedRandom,TextIOWrapper
1718 with logic to set HANDLE_FLAG_INHERIT flag on the file handle. Python 3.4+ automatically sets this according
1719 to Python docs: https://docs.python.org/3/library/os.html#fd-inheritance
1722 - Fix the PATH created by scons.bat (and other .bat files) to provide a normalized
1723 PATH. Some pythons in the 3.6 series are no longer able to handle paths which
1724 have ".." in them and end up crashing. This is done by cd'ing into the directory
1725 we want to add to the path and then using %CD% to give us the normalized directory
1726 See bug filed under Python 3.6: https://bugs.python.org/issue32457.
1727 Note: On Win32 PATH's which have not been normalized may cause undefined behavior
1728 by other executables being run by SCons (or any subprocesses of executables being run by SCons).
1729 Resolving this issue should eliminate that possibility going forward.
1731 From Andrew Featherstone
1732 - Removed unused --warn options from the man page and source code.
1735 - Fix cpp scanner regex logic to treat ifndef for py3.5+. Previously it was
1736 not properly differentiating between if, ifdef, and ifndef.
1738 From Philipp Maierhöfer
1739 - Added a __hash__ method to the class SCons.Subst.Literal. Required when substituting Literal
1740 objects when SCons runs with Python 3.
1741 - Added missing FORTRANMODDIRPREFIX to the gfortran tool.
1743 From Matthew Marinets:
1744 - Fixed an issue that caused the Java emitter to incorrectly parse arguments to constructors that
1745 implemented a class.
1747 From Fredrik Medley:
1748 - Fix exception when printing of EnviromentError messages.
1749 Specifically, this fixes error reporting of the race condition when
1750 initializing the cache which error previously was hidden.
1753 - Updated Jar builder to handle nodes and directories better
1754 - Updated Jar builder to flatten source list which could contain embedded lists
1755 - Removed some magic numbers from jar.py on behalf of Mats Wichmann (mats@linux.com)
1756 - Set the pickling protocal back to highest which was causing issues
1757 with variant dir tests. This will cause issues if reading sconsigns
1758 pickled with the previous lower protocol.
1759 - Updated swig to setup default paths for windows
1760 - Updated gettext tools to setup default paths for windows with Cygwin/MinGW setups
1761 - Add common location for default paths for cygwin and mingw in Platform modules
1762 - Updated YACC tool to work on windows with Cygwin/MinGW setups
1763 - Set the pickling protocal back to highest which was causing issues
1764 with variant dir tests. This will cause issues if reading sconsigns
1765 pickled with the previous lower protocol.
1766 - Updated FS.py to handle removal of splitunc function from python 3.7
1767 - Updated the vc.py to ignore MSVS versions where no compiler could be found
1769 From Gary Oberbrunner:
1770 - Fix bug when Installing multiple subdirs outside the source tree
1771 - fix to_str to handle None without raising exception
1772 - Fix -jN for python 3.7
1774 From Jonathon Reinhart:
1775 - Replace all instances of `int main()` in C code with `int main(void)`.
1776 Specifically, this fixes the test cases use by Configure.CheckCC() which
1777 would fail when using -Wstrict-prototypes.
1779 From Zachary Tessler:
1780 - Fix calculation of signatures for FunctionActions that contain list (or set,...)
1781 comprehensions whose expressions involve constant literals. Those constants had
1782 been ignored in signatures, so changing them did not cause targets to be rebuilt.
1785 - In the testing framework, module TestCommon, fixed must_contain(),
1786 must_not_contain(), and related methods of TestCommon class to work with
1787 substrings located at zero offset.
1788 - Added virtualenv support. A new function Virtualenv() determines whether
1789 SCons runs in a virtualenv. The search PATH may also be extended to
1790 prefer executables from the current virtualenv over the ones provided by
1791 base environment. New option --enable-virtualenv provided to import some
1792 virtualenv-related variables to SCons and extend every env['ENV']['PATH']
1793 automatically. New option --ignore-virtualenv disables this. Two
1794 environment variables, SCONS_ENABLE_VIRTUALENV and
1795 SCONS_IGNORE_VIRTUALENV are supported for the same purpose.
1798 - Add SConstruct.py, Sconstruct.py, sconstruct.py to the search path for the root SConstruct file.
1799 Allows easier debugging within Visual Studio
1800 - Change setup.py to change the install directory (via pip, or setup.py install) from scons-#.#.#
1801 to scons (Yielding <pythondir>/lib/scons/SCons/ instead of <pythondir>/lib/scons/SCons-#.#.#/).
1802 This changes SCons to better comply with normal Python installation practices.
1805 - Recognize new java 9, 10, 11 (as 9.0 and 10.0, 11.0)
1806 - Updated manpage scons.xml to fix a nested list problem
1807 - Updated doc terminiology: use prepend instead of append as appropriate
1808 - XML validity fixes from SConstruct.py change
1809 - Update wiki links to new github location
1810 - Update bug links to new github location
1811 - Make it easier for SConscript() call to fail on missing script.
1812 It was possible to call SCons.Warnings.warningAsException
1813 (not documented as a user API) to make all warnings fail. Now
1814 SConscript can take an optional must_exist flag which if true fails
1815 if the script does not exist. Not failing on missing script is
1816 now considered deprecated, and the first instance will print a
1817 deprecation message. It is now also possible to flip the scons
1818 behavior (which still defaults to warn, not fail) by calling
1819 SCons.Script.set_missing_sconscript_error, which is also not a
1820 documented interface at the moment.
1821 - Convert TestCmd.read to use with statement on open (quiets 17 py3 warnings)
1822 - Quiet py3 warning in UtilTests.py
1823 - Fix tests specifying octal constants for py3
1824 - Fix must_contain tests for py3
1825 - RPM package generation:
1826 - Fix supplying a build architecture
1827 - Disable auto debug package generation on certain rpmbuild versions
1828 - Adjust some tests to only supply build-id file on certain rpmbuild versions
1829 - Tests now use a file fixture for the repeated (trivial) main.c program.
1830 - Document and comment cleanup.
1831 - Added new Environment Value X_RPM_EXTRADEFS to supply custom settings
1832 to the specfile without adding specific logic for each one to scons.
1833 - The test for Python.h needed by swig tests is moved to get_python_platform
1834 so it does not have to be repeated in every test; picks up one failure
1835 which did not make the (previously needed) check. Windows version
1836 of get_python_platform needed some rework in case running in virtualenv.
1837 - If test opens os.devnull, register with atexit so file opens do not leak.
1838 - Fix bugs in Win32 process spawn logic to handle OSError exception correctly.
1839 - Use time.perf_counter instead of time.clock if it exists.
1840 time.clock deprecated since py3.3, due to remove in 3.8. deprecation
1841 warnings from py3.7 were failing a bunch of tests on Windows since they
1842 mess up expected stderr.
1843 - Prefer Py3's inspect.getfullargspec over deprecated inspect.getargspec.
1844 Switched to "new" (standard in Py2.7) usage of receiving a namedtuple -
1845 we were unpacking to a four-tuple, two of the items of which were unused;
1846 getfullargspec returns a named tuple with seven elements so it is a
1847 cleaner drop-in replacement using the namedtuple.
1848 - Updated the test-framework.rst documentation.
1849 - Remove obsoleted internal implementaiton of OrderedDict.
1850 - Test for tar packaging fixups
1851 - Stop using deprecated unittest asserts
1852 - messages in strip-install-dir test now os-neutral
1853 - Add xz compression format to packaging choices.
1854 - Syntax cleanups - trailing blanks, use "is" to compare with None, etc.
1855 Three uses of variables not defined are changed.
1856 - Some script changes in trying to find scons engine
1857 - Update (pep8) configure-cache script, add a --show option.
1858 - Fix for a couple of "what if tool not found" exceptions in framework.
1859 - Add Textfile/Substfile to default environment. (issue #3147)
1860 - sconsign: a couple of python3 fixes; be more tolerant of implicit
1861 entries which have no signatures; minor PEP8 changes.
1862 - Fix a couple of type mistakes (list-> string, filter type -> list)
1863 - Fix a couple of type mistakes in packaging tools: list-> string in msi,
1864 filter type -> list in ipk
1866 From Bernhard M. Wiedemann:
1867 - Update SCons' internal scons build logic to allow overriding build date
1868 with SOURCE_DATE_EPOCH for SCons itself.
1869 - Change the datestamps in SCons' docs and embedded in code use ISO 8601 format and UTC
1872 - Typo in customized decider example in user guide
1873 - Replace usage of unittest.TestSuite with unittest.main() (fix #3113)
1875 RELEASE 3.0.1 - Mon, 12 Nov 2017 15:31:33 -0700
1878 - Jar can take multiple targets, and will make a duplicate jar from the sources for each target
1879 - Added some warnings in case the Jar builder makes an implicit target
1880 - Added Jar method and changed jar build to be more specific. Jar method will take in
1881 directories or classes as source. Added more tests to JAR to ensure the jar was
1882 packaged with the correct compiled class files.
1883 - Added a No result test case to handle bug which seems unrelated to java in the
1884 swig-dependencies.py test, more info here: http://scons.tigris.org/issues/show_bug.cgi?id=2907
1885 - Added a travis script to test on ubuntu trusty now that the project is on github
1886 so that Continuus Integration tests can be run automatically. It tests most case and considers
1887 no result a pass as well. Improving this script can install more dependincies allowing for more
1891 - Updated the Jar Builder tool in Tool/__init__.py so that is doesn't force class files as
1892 sources, allowing directories to be passed, which was causing test/Java/JAR.py to fail.
1894 From William Deegan:
1895 - Fix issue where code in utility routine to_String_for_subst() had code whose result was never
1897 (Found by: James Rinkevich https://pairlist4.pair.net/pipermail/scons-users/2017-October/006358.html )
1898 - Fixed Variables.GenerateHelpText() to now use the sort parameter. Due to incorrect 2to3 fixer changes
1899 8 years ago it was being used as a boolean parameter. Now you can specify sort to be a callable, or boolean
1900 value. (True = normal sort). Manpage also updated.
1901 - Fixed Tool loading logic from exploding sys.path with many site_scons/site_tools prepended on py3.
1902 - Added additional output with time to process each SConscript file when using --debug=time.
1905 - Fixed a regression in scons-3.0.0 where "from __future__ import print_function" was imposed
1906 on the scope where SConstruct is executed, breaking existing builds using PY 2.7.
1908 From William Deegan:
1909 - Fix broken subst logic where a string with "$$(abc)" was being treated as "$(abc) and the
1910 logic for removing the signature escapes was then failing because there was no closing "$)".
1911 This was introduced by a pull request to allow recursive variable evaluations to yield a string
1912 such as "$( $( some stuff $) $)".
1914 From Zachary Tessler:
1915 - Fix incorrect warning for repeated identical builder calls that use overrides
1918 RELEASE 3.0.0 - Mon, 18 Sep 2017 08:32:04 -0700
1920 NOTE: This is a major release. You should expect that some targets may rebuild when upgrading.
1921 Significant changes in some python action signatures. Also switching between PY 2.7 and PY 3.5, 3.6
1922 will cause rebuilds.
1925 From William Blevins:

1930 - Added support for renamed imports. "import B = A;" -> A
1931 - Supports valid combinations: "import A, B, CCC = C, DDD = D : EEE = FFF;" -> A, B, C, D
1933 - May find new (previously missed) Dlang dependencies.
1934 - May cause rebuild after upgrade due to dependency changes.
1935 - Updated Fortran-related tests to pass under GCC 5/6.
1936 - Fixed SCons.Tool.Packaging.rpm.package source nondeterminism across builds.
1938 From William Deegan:
1939 - Removed deprecated tools CVS, Perforce, BitKeeper, RCS, SCCS, Subversion.
1940 - Removed deprecated module SCons.Sig
1941 - Added prioritized list of xsltproc tools to docbook. The order will now be as
1942 follows: xsltproc, saxon, saxon-xslt, xalan (with first being highest priority, first
1944 - Fixed MSVSProject example code (http://scons.tigris.org/issues/show_bug.cgi?id=2979)
1945 - Defined MS SDK 10.0 and Changed VS 2015 to use SDK 10.0
1946 - Changes to Action Function and Action Class signiture creation. NOTE: This will cause rebuilds
1947 for many builds when upgrading to SCons 3.0
1948 - Fixed Bug #3027 - "Cross Compiling issue: cannot override ranlib"
1949 - Fixed Bug #3020 - "Download link in user guide wrong. python setup.py install --version-lib broken"

1953 - Fixed Bug #3025 - (Credit to Florian : User flow86 on tigris) - Fix typo JAVACLASSSUFIX should have been
1958 - Added the capability to build Windows Store Compatible libraries that can be used
1959 with Universal Windows Platform (UWP) Apps and published to the store
1962 - Add basic support for PyPy (by deleting __slots__ from Node with a
1963 metaclass on PyPy); wrap most-used open() calls in 'with' statements to
1964 avoid too many open files.
1965 - Add __main__.py for `python -m SCons` in case it is on PYTHONPATH.
1966 - Always use highest available pickle protocol for efficiency.
1967 - Remove unused command line fallback for the zip tool.
1969 From Gaurav Juvekar:

1984 - Update LaTeX scanner to understand \import and related commands
1986 From Steve Robinson:
1987 - Add support for Visual Studio 2017. This support requires vswhere.exe a helper
1988 tool installed with newer installs of 2017. SCons expects it to be located at
1989 "C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe"
1990 It can be downloaded separately at
1991 https://github.com/Microsoft/vswhere
1994 - Allow nested $( ... $) sections
1997 - Fixed the issue with LDMODULEVERSIONFLAGS reported by Tim Jenness
1998 (https://pairlist4.pair.net/pipermail/scons-users/2016-May/004893.html).
1999 An error was causing "-Wl,Bsymbolic" being added to linker's command-line
2000 even when there was no specified value in LDMODULEVERSION and thus no
2001 need for the flags to be specified.
2002 - Added LoadableModule to the list of global functions (DefaultEnvironment
2005 From Manish Vachharajani:
2006 - Update debian rules, compat, and control to not use features
2007 deprecated or obsolete in later versions of debhelpers
2008 - Update python version to 2.7 in debian/control
2011 - Fixed PCHPDBFLAGS causing a deprecation warning on MSVC v8 and later when
2012 using PCHs and PDBs together.
2016 - Added nested / namespace tool support
2017 - Added a small fix to the python3 tool loader when loading a tool as a package
2018 - Added additional documentation to the user manual on using toolpaths with the environment
2019 This includes the use of sys.path to search for tools installed via pip or package managers
2020 - Added support for a PyPackageDir function for use with the toolpath
2023 - Reordered the default D tools from "dmd, gdc, ldc" to "dmd, ldc, gdc".
2024 - Add a ProgramAllAtOnce builder to the dmd, ldc, and gdc tools. (PR #448)
2025 - Remove a file name exception for very old Fedora LDC installation.
2026 - gdc can now handle building shared objects (tested for version 6.3.0).
2027 - Remove establishing the SharedLibrary builder in the dmd, ldc, and gdc
2028 tools, must now include the ar tool to get this builder as is required for
2029 other compiler tools.
2030 - Add clang and clang++ tools based on Paweł Tomulik's work.
2032 RELEASE 2.5.1 - Mon, 03 Nov 2016 13:37:42 -0400
2034 From William Deegan:
2035 - Add scons-configure-cache.py to packaging. It was omitted
2037 From Alexey Klimkin:
2038 - Use memoization to optimize PATH evaluation across all dependencies per
2041 RELEASE 2.5.0 - Mon, 09 Apr 2016 11:27:42 -0700
2044 - Removed a lot of compatibility methods and workarounds
2045 for Python versions < 2.7, in order to prepare the work
2046 towards a combined 2.7/3.x version. (PR #284)
2047 Also fixed the default arguments for the print_tree and
2048 render_tree methods. (PR #284, too)
2050 From William Blevins:
2051 - Added support for cross-language dependency scanning;
2052 SCons now respects scanner keys for implicit dependencies.
2053 - Notes for SCons users with heterogeneous systems.
2054 - May find new (previously missed) dependencies.
2055 - May cause rebuild after upgrade due to dependency changes.
2056 - May find new dependency errors (EG. cycles).
2057 - Discovered in some of the SCons QT tests.
2058 - Resolved missing cross-language dependencies for
2059 SWIG bindings (fixes #2264).
2060 - Corrected typo in User Guide for Scanner keyword. (PR #2959)
2061 - Install builder interacts with scanner found in SCANNERS differently.
2062 - Previous: Install builder recursively scanned implicit dependencies
2063 for scanners from SCANNER, but not for built-in (default) scanners.
2064 - Current: Install builder will not scan for implicit dependencies via
2065 either scanner source. This optimizes some Install builder behavior
2066 and brings orthogonality to Install builder scanning behavior.
2068 From William Deegan:
2069 - Add better messaging when two environments have
2070 different actions for the same target (Bug #2024)
2071 - Fix issue only with MSVC and Always build where targets
2072 marked AlwaysBuild wouldn't make it into CHANGED_SOURCES
2073 and thus yield an empty compile command line. (Bug #2622)
2074 - Fix posix platform escaping logic to properly handle paths
2075 with parens in them "()". (Bug #2225)
2078 - Intel Compiler 2016 (Linux/Mac) update for tool directories.
2080 From Adarsh Sanjeev:
2081 - Fix for issue #2494: Added string support for Chmod function.
2084 - change cache to use 2 character subdirectories, rather than one character,
2085 so as not to give huge directories for large caches, a situation which
2086 causes issues for NFS.
2087 For existing caches, you will need to run the scons-configure-cache.py
2088 script to update them to the new format. You will get a warning every time
2089 you build until you co this.
2090 - Fix a bunch of unit tests on windows
2092 RELEASE 2.4.1 - Mon, 07 Nov 2015 10:37:21 -0700
2094 From Arfrever Frehtes Taifersar Arahesis:
2095 - Fix for Bug # 2791 - Setup.py fails unnecessarily under Jython.

2099 packaging, such that they allow for commercial use too (#2985).
2101 From William Blevins:
2102 - InstallVersionedLib now available in the DefaultEnvironment context.
2103 - Improves orthogonality of use cases between different Install functions.
2106 - Added new configure check, CheckProg, to check for
2107 existence of a program.
2109 From Andrew Featherstone:
2110 - Fix for issue #2840 - Fix for two environments specifying same target with different
2111 actions not throwing hard error. Instead SCons was incorrectly issuing a warning
2115 - Add support `Microsoft Visual C++ Compiler for Python 2.7'
2116 Compiler can be obtained at: https://www.microsoft.com/en-us/download/details.aspx?id=44266

2125 - Reimplemented versioning for shared libraries, with the following effects
2126 - Fixed tigris issues #3001, #3006.
2127 - Fixed several other issues not reported to tigris, including:
2128 issues with versioned libraries in subdirectories with tricky names,
2129 issues with versioned libraries and variant directories,
2130 issue with soname not being injected to library when using D linkers,
2131 - Switched to direct symlinks instead of daisy-chained ones -- soname and
2132 development symlinks point directly to the versioned shared library now),
2134 https://www.debian.org/doc/debian-policy/ch-sharedlibs.html
2135 https://fedoraproject.org/wiki/Packaging:Guidelines#Devel_Packages
2136 https://bitbucket.org/scons/scons/pull-requests/247/new-versioned-libraries-gnulink-cyglink/diff#comment-10063929
2137 - New construction variables to allow override default behavior: SONAME,
2138 SHLIBVERSIONFLAGS, _SHLIBVERSIONFLAGS, SHLIBNOVERSIONSYMLINKS,
2139 LDMODULEVERSION, LDMODULEVERSIONFLAGS, _LDMODULEVERSIONFLAGS,
2140 LDMODULENOVERSIONSYMLINKS.
2141 - Changed logic used to configure the versioning machinery from
2142 platform-centric to linker-oriented.
2143 - The SHLIBVERSION/LDMODULEVERSION variables are no longer validated by
2144 SCons (more freedom to users).
2145 - InstallVersionedLib() doesn't use SHLIBVERSION anymore.
2146 - Enchanced docs for the library versioning stuff.
2147 - New tests for versioned libraries.
2148 - Library versioning is currently implemented for the following linker
2149 tools: 'cyglink', 'gnulink', 'sunlink'.
2150 - Fix to swig tool - pick-up 'swig', 'swig3.0' and 'swig2.0' (in order).
2151 - Fix to swig tool - respect env['SWIG'] provided by user.
2155 RELEASE 2.4.0 - Mon, 21 Sep 2015 08:56:00 -0700
2158 - Switched several core classes to use "slots", to
2159 reduce the overall memory consumption in large
2160 projects (fixes #2180, #2178, #2198)
2161 - Memoizer counting uses decorators now, instead of
2162 the old metaclasses approach.

3002 Patch from Stefan Hepp.
3004 - Change scanner to properly search for included file from the
3005 directory of the main file instead of the file it is included from.
3006 Also update the emitter to add the .aux file associated with

3346 no version number) after "scons-local-{VERSION}".
3350 - Fix the user's ability to interrupt the TeX build chain.
3352 - Fix the TeX builder's allowing the user to specify the target name,
3353 instead of always using its default output name based on the source.
3355 - Iterate building TeX output files until all warning are gone
3356 and the auxiliary files stop changing, or until we reach the

3568 mistakenly reporting failures after any individual build fails.
3570 - Fix calling File() as a File object method in some circumstances.
3572 - Fix setup.py installation on Mac OS X so SCons gets installed

3626 in the search path list.
3630 - Fix expansion of $FORTRANMODDIR in the default Fortran command line(s)
3631 when it's set to something like ${TARGET.dir}.
3635 RELEASE 0.98.2 - Sun, 20 Apr 2008 23:38:56 -0700
3639 - Fix a bug in Fortran suffix computation that would cause SCons to
3640 run out of memory on Windows systems.

3669 From David Cournapeau:
3671 - Various missing Fortran-related construction variables have been added.
3673 - SCons now uses the program specified in the $FORTRAN construction
3674 variable to link Fortran object files.
3676 - Fortran compilers on Linux (Intel, g77 and gfortran) now add the -fPIC
3677 option by default when compilling shared objects.
3679 - New 'sunf77', 'sunf90' and 'sunf95' Tool modules have been added to
3680 support Sun Fortran compilers. On Solaris, the Sun Fortran compilers
3681 are used in preference to other compilers by default.
3683 - Fortran support now uses gfortran in preference to g77.
3685 - Fortran file suffixes are now configurable through the
3686 $F77FILESUFFIXES, $F90FILESUFFIXES, $F95FILESUFFIXES and
3687 $FORTRANFILESUFFIXES variables.
3691 - Make the -d, -e, -w and --no-print-directory options "Ignored for
3692 compatibility." (We're not going to implement them.)
3694 - Fix a serious inefficiency in how SCons checks for whether any source
3695 files are missing when a Builder call creates many targets from many
3698 - In Java projects, make the target .class files depend only on the
3699 specific source .java files where the individual classes are defined.
3701 - Don't store duplicate source file entries in the .sconsign file so
3702 we don't endlessly rebuild the target(s) for no reason.
3704 - Add a Variables object as the first step towards deprecating the
3705 Options object name. Similarly, add BoolVariable(), EnumVariable(),
3706 ListVariable(), PackageVariable() and PathVariable() functions
3707 as first steps towards replacing BoolOption(), EnumOption(),
3708 ListOption(), PackageOption() and PathOption().
3710 - Change the options= keyword argument to the Environment() function
3711 to variables=, to avoid confusion with SCons command-line options.
3712 Continue supporting the options= keyword for backwards compatibility.
3714 - When $SWIGFLAGS contains the -python flag, expect the generated .py
3715 file to be in the same (sub)directory as the target.

3718 command line even when $CXXFLAGS has been redefined.
3720 - Fix --interactive with -u/-U/-D when a VariantDir() is used.
3722 From Anatoly Techtonik:
3724 - Have the scons.bat file add the script execution directory to its

3729 - Fix passing variable names as a list to the Return() function.
3731 From Matthew Wesley:
3733 - Add support for the GDC 'D' language compiler.
3737 RELEASE 0.98 - Sun, 30 Mar 2008 23:33:05 -0700
3741 - Fix the --keep-going flag so it builds all possible targets even when
3742 a later top-level target depends on a child that failed its build.
3744 - Fix being able to use $PDB and $WINDWOWS_INSERT_MANIFEST together.
3746 - Don't crash if un-installing the Intel C compiler leaves left-over,
3747 dangling entries in the Windows registry.
3749 - Improve support for non-standard library prefixes and suffixes by
3750 stripping all prefixes/suffixes from file name string as appropriate.
3752 - Reduce the default stack size for -j worker threads to 256 Kbytes.
3753 Provide user control over this value by adding --stack-size and
3754 --warn=stack-size options, and a SetOption('stack_size') function.
3756 - Fix a crash on Linux systems when trying to use the Intel C compiler
3757 and no /opt/intel_cc_* directories are found.
3759 - Improve using Python functions as actions by incorporating into
3760 a FunctionAction's signature:
3761 - literal values referenced by the byte code.
3762 - values of default arguments
3763 - code of nested functions
3764 - values of variables captured by closures
3765 - names of referenced global variables and functions
3767 - Fix the closing message when --clean and --keep-going are both
3768 used and no errors occur.
3770 - Add support for the Intel C compiler on Mac OS X.
3772 - Speed up reading SConscript files by about 20% (for some
3773 configurations) by: 1) optimizing the SCons.Util.is_*() and
3774 SCons.Util.flatten() functions; 2) avoiding unnecessary os.stat()
3775 calls by using a File's .suffix attribute directly instead of
3778 From Jérôme Berger:
3780 - Have the D language scanner search for .di files as well as .d files.
3782 - Add a find_include_names() method to the Scanner.Classic class to
3783 abstract out how included names can be generated by subclasses.
3785 - Allow the D language scanner to detect multiple modules imported by
3788 From Konstantin Bozhikov:
3790 - Support expansion of construction variables that contain or refer
3791 to lists of other variables or Nodes within expansions like $CPPPATH.
3793 - Change variable substitution (the env.subst() method) so that an
3794 input sequence (list or tuple) is preserved as a list in the output.
3796 From David Cournapeau:
3798 - Add a CheckDeclaration() call to configure contexts.
3800 - Improve the CheckTypeSize() code.
3802 - Add a Define() call to configure contexts, to add arbitrary #define
3803 lines to a generated configure header file.
3805 - Add a "gfortran" Tool module for the GNU F95/F2003 compiler.
3807 - Avoid use of -rpath with the Mac OS X linker.

3810 the various #define/#undef lines are doing.
3814 - Support the ability to subclass the new-style "str" class as input
3817 - Improve the performance of our type-checking by using isinstance()
3818 with new-style classes.
3820 - Fix #include (and other $*PATH variables searches) of files with
3821 absolute path names. Don't die if they don't exist (due to being
3822 #ifdef'ed out or the like).
3824 - Fix --interactive mode when Default(None) is used.
3826 - Fix --debug=memoizer to work around a bug in base Python 2.2 metaclass
3827 initialization (by just not allowing Memoization in Python versions

3831 log files that contain no results specified by the --which option.
3833 - Fix the max Y of vertical bars drawn by "scons-time --fmt=gnuplot".
3835 - On Mac OS X, account for the fact that the header file generated
3836 from a C++ file will be named (e.g.) file.cpp.h, not file.hpp.
3838 - Fix floating-point numbers confusing the Java parser about
3839 generated .class file names in some configurations.
3841 - Document (nearly) all the values you can now fetch with GetOption().
3843 - Fix use of file names containing strings of multiple spaces when
3844 using ActionFactory instances like the Copy() or Move() function.
3846 - Fix a 0.97 regression when using a variable expansion (like
3847 $OBJSUFFIX) in a source file name to a builder with attached source
3848 builders that match suffix (like Program()+Object()).
3850 - Have the Java parser recognize generics (surrounded by angle brackets)
3851 so they don't interfere with identifying anonymous inner classes.
3853 - Avoid an infinite loop when trying to use saved copies of the
3854 env.Install() or env.InstallAs() after replacing the method
3857 - Improve the performance of setting construction variables.
3859 - When cloning a construction environment, avoid over-writing an
3860 attribute for an added method if the user explicitly replaced it.
3862 - Add a warning about deprecated support for Python 1.5, 2.0 and 2.1.
3864 - Fix being able to SetOption('warn', ...) in SConscript files.
3866 - Add a warning about env.Copy() being deprecated.
3868 - Add warnings about the --debug={dtree,stree,tree} options
3871 - Add VariantDir() as the first step towards deprecating BuildDir().
3872 Add the keyword argument "variant_dir" as the replacement for
3875 - Add warnings about the {Target,Source}Signatures() methods and
3876 functions being deprecated.
3880 - Enhance TeX and LaTeX support to work with BuildDir(duplicate=0).
3882 - Re-run LaTeX when it issues a package warning that it must be re-run.
3884 From Leanid Nazdrynau:
3886 - Have the Copy() action factory preserve file modes and times
3887 when copying individual files.
3891 - If $JARCHDIR isn't set explicitly, use the .java_classdir attribute
3892 that was set when the Java() Builder built the .class files.
3896 - Document the Dir(), File() and Entry() methods of Dir and File Nodes.
3898 - Add the parse_flags option when creating Environments
3900 From Gary Oberbrunner:
3902 - Make File(), Dir() and Entry() return a list of Nodes when passed
3903 a list of names, instead of trying to make a string from the name
3904 list and making a Node from that string.
3906 - Fix the ability to build an Alias in --interactive mode.
3908 - Fix the ability to hash the contents of actions for nested Python
3909 functions on Python versions where the inability to pickle them
3910 returns a TypeError (instead of the documented PicklingError).
3914 - Fix use of the Intel C compiler when the top compiler directory,
3915 but not the compiler version, is specified.
3917 - Handle Intel C compiler network license files (port@system).
3921 - Fix how Python Value Nodes are printed in --debug=explain output.
3925 - Add a --interactive option that starts a session for building (or
3926 cleaning) targets without re-reading the SConscript files every time.
3928 - Fix use of readline command-line editing in --interactive mode.
3930 - Have the --interactive mode "build" command with no arguments
3931 build the specified Default() targets.
3933 - Fix the Chmod(), Delete(), Mkdir() and Touch() Action factories to
3934 take a list (of Nodes or strings) as arguments.
3936 From Vaclav Smilauer:
3938 - Fix saving and restoring an Options value of 'all' on Python
3939 versions where all() is a builtin function.
3941 From Daniel Svensson:
3943 - Code correction in SCons.Util.is_List().
3947 - Support the SWIG %module statement with following modifiers in
3948 parenthese (e.g., '%module(directors="1")').
3952 RELEASE 0.97.0d20071212 - Wed, 12 Dec 2007 09:29:32 -0600
3956 - Fix occasional spurious rebuilds and inefficiency when using
3957 --implicit-cache and Builders that produce multiple targets.
3959 - Allow SCons to not have to know about the builders of generated
3960 files when BuildDir(duplicate=0) is used, potentially allowing some
3961 SConscript files to be ignored for smaller builds.
3963 From David Cournapeau:
3965 - Add a CheckTypeSize() call to configure contexts.
3969 - Make the "contents" of Alias Nodes a concatenation of the children's
3970 content signatures (MD5 checksums), not a concatenation of the
3971 children's contents, to avoid using large amounts of memory during
3972 signature calculation.
3976 - Fix a lot of typos in the man page and User's Guide.
3978 From Geoffrey Irving:
3980 - Speed up conversion of paths in .sconsign files to File or Dir Nodes.
3984 - Add an Options.UnknownOptions() method that returns any settings
3985 (from the command line, or whatever dictionary was passed in)
3986 that aren't known to the Options object.
3988 - Add a Glob() function.
3990 - When removing targets with the -c option, use the absolute path (to
3991 avoid problems interpreting BuildDir() when the top-level directory
3992 is the source directory).
3994 - Fix problems with Install() and InstallAs() when called through a
3995 clone (of a clone, ...) of a cloned construction environment.
3997 - When executing a file containing Options() settings, add the file's
3998 directory to sys.path (so modules can be imported from there) and
3999 explicity set __name__ to the name of the file so the statement's
4000 in the file can deduce the location if they need to.
4002 - Fix an O(n^2) performance problem when adding sources to a target
4003 through calls to a multi Builder (including Aliases).
4005 - Redefine the $WINDOWSPROGMANIFESTSUFFIX and
4006 $WINDOWSSHLIBMANIFESTSUFFIX variables so they pick up changes to
4007 the underlying $SHLIBSUFFIX and $PROGSUFFIX variables.
4009 - Add a GetBuildFailures() function that can be called from functions
4010 registered with the Python atexit module to print summary information
4011 about any failures encountered while building.
4013 - Return a NodeList object, not a Python list, when a single_source
4014 Builder like Object() is called with more than one file.
4016 - When searching for implicit dependency files in the directories
4017 in a $*PATH list, don't create Dir Nodes for directories that
4018 don't actually exist on-disk.
4020 - Add a Requires() function to allow the specification of order-only
4021 prerequisites, which will be updated before specified "downstream"
4022 targets but which don't actually cause the target to be rebuilt.
4024 - Restore the FS.{Dir,File,Entry}.rel_path() method.
4026 - Make the default behavior of {Source,Target}Signatures('timestamp')
4027 be equivalent to 'timestamp-match', not 'timestamp-newer'.
4029 - Fix use of CacheDir with Decider('timestamp-newer') by updating
4030 the modification time when copying files from the cache.
4032 - Fix random issues with parallel (-j) builds on Windows when Python
4033 holds open file handles (especially for SCons temporary files,
4034 or targets built by Python function actions) across process creation.
4036 From Maxim Kartashev:
4038 - Fix test scripts when run on Solaris.
4040 From Gary Oberbrunner:
4042 - Fix Glob() when a pattern is in an explicitly-named subdirectory.
4044 From Philipp Scholl:
4046 - Fix setting up targets if multiple Package builders are specified

4055 - Fix the wix Tool module to handle null entries in $PATH variables.
4057 - Move the documentation of Install() and InstallAs() from the list
4058 of functions to the list of Builders (now that they're implemented
4061 - Allow env.CacheDir() to be set per construction environment. The
4062 global CacheDir() function now sets an overridable global default.
4064 - Add an env.Decider() method and a Node.Decider() method that allow
4065 flexible specification of an arbitrary function to decide if a given
4066 dependency has changed since the last time a target was built.
4068 - Don't execute Configure actions (while reading SConscript files)
4069 when cleaning (-c) or getting help (-h or -H).
4071 - Add to each target an implicit dependency on the external command(s)
4072 used to build the target, as found by searching env['ENV']['PATH']
4073 for the first argument on each executed command line.
4075 - Add support for a $IMPLICIT_COMMAND_DEPENDENCIES construction
4076 variabe that can be used to disable the automatic implicit
4077 dependency on executed commands.
4079 - Add an "ensure_suffix" keyword to Builder() definitions that, when
4080 true, will add the configured suffix to the targets even if it looks
4081 like they already have a different suffix.
4083 - Add a Progress() function that allows for calling a function or string
4084 (or list of strings) to display progress while walking the DAG.
4086 - Allow ParseConfig(), MergeFlags() and ParseFlags() to handle output
4087 from a *config command with quoted path names that contain spaces.
4089 - Make the Return() function stop processing the SConscript file and
4090 return immediately. Add a "stop=" keyword argument that can be set
4091 to False to preserve the old behavior.
4093 - Fix use of exitstatfunc on an Action.
4095 - Introduce all man page function examples with "Example:" or "Examples:".
4097 - When a file gets added to a directory, make sure the directory gets
4098 re-scanned for the new implicit dependency.
4100 - Fix handling a file that's specified multiple times in a target
4101 list so that it doesn't cause dependent Nodes to "disappear" from
4102 the dependency graph walk.
4106 - Avoid race conditions with same-named files and directory creation
4107 when pushing copies of files to CacheDir().
4111 - Handle $ in Java class names.
4113 From Gary Oberbrunner:
4115 - Add support for the Intel C compiler on Windows64.
4117 - On SGI IRIX, have $SHCXX use $CXX by default (like other platforms).
4121 - When Cloning a construction environment, set any variables before
4122 applying tools (so the tool module can access the configured settings)
4123 and re-set them after (so they end up matching what the user set).
4125 From Matthias Troffaes:
4127 - Make sure extra auxiliary files generated by some LaTeX packages
4128 and not ending in .aux also get deleted by scons -c.
4132 - Add a $JAVABOOTCLASSPATH variable for directories to be passed to the
4133 javac -bootclasspath option.
4135 From Christoph Wiedemann:
4137 - Add implicit dependencies on the commands used to build a target.
4142 RELEASE 0.97.0d20070809 - Fri, 10 Aug 2007 10:51:27 -0500
4144 From Lars Albertsson:
4146 - Don't error if a #include line happens to match a directory
4147 somewhere on a path (like $CPPPATH, $FORTRANPATH, etc.).
4149 From Mark Bertoglio:
4151 - Fix listing multiple projects in Visual Studio 7.[01] solution files,
4152 including generating individual project GUIDs instead of re-using
4157 - Add /opt/SUNWspro/bin to the default execution PATH on Solaris.
4161 - Only expect the Microsoft IDL compiler to emit *_p.c and *_data.c
4162 files if the /proxy and /dlldata switches are used (respectively).
4166 - Have --debug=explain report if a target is being rebuilt because
4167 AlwaysBuild() is specified (instead of "unknown reasons").
4169 - Support {Get,Set}Option('help') to make it easier for SConscript
4170 files to tell if a help option (-h, --help, etc.) has been specified.
4172 - Support {Get,Set}Option('random') so random-dependency interaction
4173 with CacheDir() is controllable from SConscript files.
4175 - Add a new AddOption() function to support user-defined command-
4176 line flags (like --prefix=, --force, etc.).
4178 - Replace modified Optik version with new optparse compatibility module
4179 for command line processing in Scripts/SConsOptions.py
4181 - Push and retrieve built symlinks to/from a CacheDir() as actual
4182 symlinks, not by copying the file contents.
4184 - Fix how the Action module handles stringifying the shared library
4185 generator in the Tool/mingw.py module.
4187 - When generating a config.h file, print "#define HAVE_{FEATURE} 1"
4188 instad of just "#define HAVE_{FEATURE}", for more compatibility
4189 with Autoconf-style projects.
4191 - Fix expansion of $TARGET, $TARGETS, $SOURCE and $SOURCES keywords in
4192 Visual C/C++ PDB file names.
4194 - Fix locating Visual C/C++ PDB files in build directories.
4196 - Support an env.AddMethod() method and an AddMethod() global function
4197 for adding a new method, respectively, to a construction environment
4198 or an arbitrary object (such as a class).
4200 - Fix the --debug=time option when the -j option is specified and all
4201 files are up to date.
4203 - Add a $SWIGOUTDIR variable to allow setting the swig -outdir option,
4204 and use it to identify files created by the swig -java option.
4206 - Add a $SWIGPATH variable that specifies the path to be searched
4207 for included SWIG files, Also add related $SWIGINCPREFIX and
4208 $SWIGINCSUFFIX variables that specify the prefix and suffix to
4209 be be added to each $SWIGPATH directory when expanded on the SWIG
4212 - More efficient copying of construction environments (mostly borrowed
4213 from copy.deepcopy() in the standard Python library).
4215 - When printing --tree=prune output, don't print [brackets] around
4216 source files, only do so for built targets with children.
4218 - Fix interpretation of Builder source arguments when the Builder has
4219 a src_suffix *and* a source_builder and the argument has no suffix.
4221 - Fix use of expansions like ${TARGET.dir} or ${SOURCE.dir} in the
4222 following construction variables: $FORTRANMODDIR, $JARCHDIR,
4223 $JARFLAGS, $LEXFLAGS, $SWIGFLAGS, $SWIGOUTDIR and $YACCFLAGS.
4225 - Fix dependencies on Java files generated by SWIG so they can be
4226 detected and built in one pass.
4228 - Fix SWIG when used with a BuildDir().
4230 From Leanid Nazdrynau:
4232 - When applying Tool modules after a construction environment has
4233 already been created, don't overwrite existing $CFILESUFFIX and
4234 $CXXFILESUFFIX value.
4236 - Support passing the Java() builder a list of explicit .java files
4237 (not only a list of directories to be scanned for .java files).
4239 - Support passing .java files to the Jar() and JavaH() builders, which
4240 then use the builder underlying the Java() builder to turn them into
4241 .class files. (That is, the Jar()-Java() chain of builders become
4242 multi-step, like the Program()-Object()-CFile() builders.)
4244 - Support passing SWIG .i files to the Java builders (Java(),
4245 Jar(), JavaH()), to cause intermediate .java files to be created
4248 - Add $JAVACLASSPATH and $JAVASOURCEPATH variables, that get added to
4249 the javac "-classpath" and "-sourcepath" options. (Note that SCons
4250 does *not* currently search these paths for implicit dependencies.)
4252 - Commonize initialization of Java-related builders.
4256 - Find Java anonymous classes when the next token after the name is
4257 an open parenthesis.
4259 From Gary Oberbrunner:
4261 - Fix a code example in the man page.
4265 - Add support for the file names that Java 1.5 (and 1.6) generates for
4266 nested anonymous inner classes, which are different from Java 1.4.
4270 - Allow worker threads to terminate gracefully when all jobs are
4275 - Add LaTeX scanner support for finding dependencies specified with
4276 the \usepackage{} directive.
4280 RELEASE 0.97 - Thu, 17 May 2007 08:59:41 -0500
4284 - Fix a bug that would make parallel builds stop in their tracks if
4285 Nodes that depended on lists that contained some Nodes built together
4286 caused the reference count to drop below 0 if the Nodes were visited
4287 and commands finished in the wrong order.
4289 - Make sure the DirEntryScanner doesn't choke if it's handed something
4290 that's not a directory (Node.FS.Dir) Node.
4294 RELEASE 0.96.96 - Thu, 12 Apr 2007 12:36:25 -0500
4296 NOTE: This is (Yet) a(nother) pre-release of 0.97 for testing purposes.
4300 - Man page fix: remove cut-and-paste sentence in NoCache() description.
4302 From Dmitry Grigorenko and Gary Oberbrunner:
4304 - Use the Intel C++ compiler, not $CC, to link C++ source.
4308 - Fix the man page example of propagating a user's external environment.
4312 - Back out (most of) the Windows registry installer patch, which
4313 seems to not work on some versions of Windows.
4315 - Don't treat Java ".class" attributes as defining an inner class.
4317 - Fix detecting an erroneous Java anonymous class when the first
4318 non-skipped token after a "new" keyword is a closing brace.
4320 - Fix a regression when a CPPDEFINES list contains a tuple, the second
4321 item of which (the option value) is a construction variable expansion
4322 (e.g. $VALUE) and the value of the variable isn't a string.
4324 - Improve the error message if an IOError (like trying to read a
4325 directory as a file) occurs while deciding if a node is up-to-date.
4327 - Fix "maximum recursion" / "unhashable type" errors in $CPPPATH
4328 PathList expansion if a subsidiary expansion yields a stringable,
4331 - Generate API documentation from the docstrings (using epydoc).
4333 - Fix use of --debug=presub with Actions for out-of-the-box Builders.
4335 - Fix handling nested lists within $CPPPATH, $LIBPATH, etc.
4337 - Fix a "builders_used" AttributeError that real-world Qt initialization
4338 triggered in the refactored suffix handling for Builders.
4340 - Make the reported --debug=time timings meaningful when used with -j.
4341 Better documentation of what the times mean.
4343 - User Guide updates: --random, AlwaysBuild(), --tree=,
4344 --debug=findlibs, --debug=presub, --debug=stacktrace,
4347 - Document (in both man page and User's Guide) that --implicit-cache
4348 ignores changes in $CPPPATH, $LIBPATH, etc.
4350 From Jean-Baptiste Lab:
4352 - Remove hard-coded dependency on Python 2.2 from Debian packaging files.
4356 - Handle spaces in the build target name in Visual Studio project files.
4360 - Re-run LaTeX after BibTeX has been re-run in response to a changed
4363 From Joel B. Mohler:
4365 - Make additional TeX auxiliary files (.toc, .idx and .bbl files)
4366 Precious so their removal doesn't affect whether the necessary
4367 sections are included in output PDF or PostScript files.
4369 From Gary Oberbrunner:
4371 - Fix the ability to import modules in the site_scons directory from
4376 - Make sure parallel (-j) builds all targets even if they show up
4377 multiple times in the child list (as a source and a dependency).
4379 From Matthias Troffaes:
4381 - Don't re-run TeX if the triggering strings (\makeindex, \bibliography
4382 \tableofcontents) are commented out.
4386 - Fix use of custom include and lib paths with Visual Studio 8.
4388 - Select the default .NET Framework SDK Dir based on the version of
4389 Visual Studio being used.
4393 RELEASE 0.96.95 - Mon, 12 Feb 2007 20:25:16 -0600
4395 From Anatoly Techtonik:
4397 - Add the scons.org URL and a package description to the setup.py
4400 - Have the Windows installer add a registry entry for scons.bat in the
4401 "App Paths" key, so scons.bat can be executed without adding the
4402 directory to the %PATH%. (Python itself works this way.)
4406 - Fix looking for default paths in Visual Studio 8.0 (and later).
4408 - Add -lm to the list of default D libraries for linking.
4412 - Provide a more complete write-your-own-Scanner example in the man page.
4414 From Ralf W. Grosse-Kunstleve:
4416 - Contributed upstream Python change to our copied subprocess.py module
4417 for more efficient standard input processing.
4421 - Fix the Node.FS.Base.rel_path() method when the two nodes are on
4422 different drive letters. (This caused an infinite loop when
4423 trying to write .sconsign files.)
4425 - Fully support Scanners that use a dictionary to map file suffixes
4428 - Support delayed evaluation of the $SPAWN variable to allow selection
4429 of a function via ${} string expansions.
4431 - Add --srcdir as a synonym for -Y/--repository.
4433 - Document limitations of #include "file.h" with Repository().
4435 - Fix use of a toolpath under the source directory of a BuildDir().
4437 - Fix env.Install() with a file name portion that begins with '#'.
4439 - Fix ParseConfig()'s handling of multiple options in a string that's
4440 replaced a *FLAGS construction variable.
4442 - Have the C++ tools initialize common C compilation variables ($CCFLAGS,
4443 $SHCCFLAGS and $_CCCOMCOM) even if the 'cc' Tool isn't loaded.
4445 From Leanid Nazdrynau:
4447 - Fix detection of Java anonymous classes if a newline precedes the
4450 From Gary Oberbrunner:
4452 - Document use of ${} to execute arbitrary Python code.
4455 1) automatically adding a site_scons subdirectory (in the top-level
4456 SConstruct directory) to sys.path (PYTHONPATH);
4457 2) automatically importing site_scons/site_init.py;
4458 3) automatically adding site_scons/site_tools to the toolpath.
4462 - Change ParseConfig() to preserve white space in arguments passed in
4467 - Fix adding explicitly-named Java inner class files (and any
4468 other file names that may contain a '$') to Jar files.
4472 - Add a NoCache() function to mark targets as unsuitable for propagating
4473 to (or retrieving from) a CacheDir().
4477 - If the swig -noproxy option is used, it won't generate a .py file,
4478 so don't emit it as a target that we expect to be built.
4482 RELEASE 0.96.94 - Sun, 07 Jan 2007 18:36:20 -0600
4484 NOTE: This is a pre-release of 0.97 for testing purposes.
4488 - Allow arbitrary white space after a SWIG %module declaration.
4492 - When compiling resources under MinGW, make sure there's a space
4493 between the --include-dir option and its argument.
4497 - Alleviate long command line issues on Windows by executing command
4498 lines directly via os.spawnv() if the command line doesn't need
4499 shell interpretation (has no pipes, redirection, etc.).
4501 From Walter Franzini:
4503 - Exclude additional Debian packaging files from the copyright check.
4507 - Handle the conflict between the impending Python 2.6 'as' keyword
4508 and our Tool/as.py module name.
4512 - Speed up the Node.FS.Dir.rel_path() method used to generate path names
4513 that get put into the .sconsign* file(s).
4515 - Optimize Node.FS.Base.get_suffix() by computing the suffix once, up
4516 front, when we set the Node's name. (Duh...)
4518 - Reduce the Memoizer's responsibilities to simply counting hits and
4519 misses when the --debug=memoizer option is used, not to actually
4520 handling the key calculation and memoization itself. This speeds
4521 up some configurations significantly, and should cause no functional
4524 - Add a new scons-time script with subcommands for generating
4525 consistent timing output from SCons configurations, extracting
4526 various information from those timings, and displaying them in
4529 - Reduce some unnecessary stat() calls from on-disk entry type checks.
4531 - Fix SideEffect() when used with -j, which was badly broken in 0.96.93.
4533 - Propagate TypeError exceptions when evaluating construction variable
4534 expansions up the stack, so users can see what's going on.
4536 - When disambiguating a Node.FS.Entry into a Dir or File, don't look
4537 in the on-disk source directory until we've confirmed there's no
4538 on-disk entry locally and there *is* one in the srcdir. This avoids
4539 creating a phantom Node that can interfere with dependencies on
4542 - Add an AllowSubstExceptions() function that gives the SConscript
4543 files control over what exceptions cause a string to expand to ''
4544 vs. terminating processing with an error.
4546 - Allow the f90.py and f95.py Tool modules to compile earlier source
4547 source files of earlier Fortran version.
4549 - Fix storing signatures of files retrieved from CacheDir() so they're
4550 correctly identified as up-to-date next invocation.
4552 - Make sure lists of computed source suffixes cached by Builder objects
4553 don't persist across changes to the list of source Builders (so the
4554 addition of suffixes like .ui by the qt.py Tool module take effect).
4556 - Enhance the bootstrap.py script to allow it to be used to execute
4557 SCons more easily from a checked-out source tree.
4561 - Fix post-Memoizer value caching misspellings in Node.FS._doLookup().
4563 From Rob Managan, Dmitry Mikhin and Joel B. Mohler:
4565 - Handle TeX/LaTeX files in subdirectories by changing directory
4566 before invoking TeX/LaTeX.
4568 - Scan LaTeX files for \bibliography lines.
4570 - Support multiple file names in a "\bibliography{file1,file2}" string.
4572 - Handle TeX warnings about undefined citations.
4574 - Support re-running LaTeX if necessary due to a Table of Contents.
4578 - Return LaTeX if "Rerun to get citations correct" shows up on the next
4579 line after the "Warning:" string.
4581 From Gary Oberbrunner:
4583 - Add #include lines to fix portability issues in two tests.
4585 - Eliminate some unnecessary os.path.normpath() calls.
4587 - Add a $CFLAGS variable for C-specific options, leaving $CCFLAGS
4588 for options common to C and C++.
4592 - Have the error message print the missing file that Qt can't find.
4596 - Fix env.MergeFlags() appending to construction variable value of None.
4600 - Fix the "sconsign" script when the .sconsign.dblite file is explicitly
4601 specified on the command line (and not intuited from the old way of
4602 calling it with just ".sconsign").
4604 From Jose Pablo Ezequiel "Pupeno" Fernandez Silva:
4606 - Give the 'lex' tool knowledge of the additional target files produced
4607 by the flex "--header-file=" and "--tables-file=" options.
4609 - Give the 'yacc' tool knowledge of the additional target files produced
4610 by the bison "-g", "--defines=" and "--graph=" options.
4612 - Generate intermediate files with Objective C file suffixes (.m) when
4613 the lex and yacc source files have appropriate suffixes (.lm and .ym).
4617 - Have the mslink.py Tool only look for a 'link' executable on Windows
4620 From Vaclav Smilauer:
4622 - Add support for a "srcdir" keyword argument when calling a Builder,
4623 which will add a srcdir prefix to all non-relative string sources.
4625 From Jonathan Ultis:
4627 - Allow Options converters to take the construction environment as
4628 an optional argument.
4632 RELEASE 0.96.93 - Mon, 06 Nov 2006 00:44:11 -0600
4634 NOTE: This is a pre-release of 0.97 for testing purposes.
4638 - Allow Python Value Nodes to be Builder targets.
4642 - Only filter Visual Studio common filename prefixes on complete
4647 - Fix the build of the SCons documentation on systems that don't
4648 have "python" in the $PATH.
4652 - Enhance ParseConfig() to recognize options that begin with '+'.
4654 From John Calcote, Elliot Murphy:
4656 - Document ways to override the CCPDBFLAGS variable to use the
4657 Microsoft linker's /Zi option instead of the default /Z7.
4659 From Christopher Drexler:
4661 - Make SCons aware bibtex must be called if any \include files
4662 cause creation of a bibliography.
4664 - Make SCons aware that "\bilbiography" in TeX source files means
4665 that related .bbl and .blg bibliography files will be created.
4666 (NOTE: This still needs to search for the string in \include files.)
4670 - Fix inconsistent handling of Action strfunction arguments.
4672 - Preserve white space in display Action strfunction strings.
4674 From James Y. Knight and Gerard Patel:
4676 - Support creation of shared object files from assembly language.
4680 - Speed up the Taskmaster significantly by avoiding unnecessary
4681 re-scans of Nodes to find out if there's work to be done, having it
4682 track the currently-executed top-level target directly and not
4683 through its presence on the target list, and eliminating some other
4684 minor list(s), method(s) and manipulation.
4686 - Fix the expansion of $TARGET and $SOURCE in the expansion of
4687 $INSTALLSTR displayed for non-environment calls to InstallAs().
4689 - Fix the ability to have an Alias() call refer to a directory
4690 name that's not identified as a directory until later.
4692 - Enhance runtest.py with an option to use QMTest as the harness.
4693 This will become the default behavior as we add more functionality
4696 - Let linking on mingw use the default function that chooses $CC (gcc)
4697 or $CXX (g++) depending on whether there are any C++ source files.
4699 - Work around a bug in early versions of the Python 2.4 profile module
4700 that caused the --profile= option to fail.
4702 - Only call Options validators and converters once when initializing a
4703 construction environment.
4705 - Fix the ability of env.Append() and env.Prepend(), in all known Python
4706 versions, to handle different input value types when the construction
4707 variable being updated is a dictionary.
4709 - Add a --cache-debug option for information about what files it's
4710 looking for in a CacheDir().
4712 - Document the difference in construction variable expansion between
4713 {Action,Builder}() and env.{Action,Builder}().
4715 - Change the name of env.Copy() to env.Clone(), keeping the old name
4716 around for backwards compatibility (with the intention of eventually
4717 phasing it out to avoid confusion with the Copy() Action factory).
4721 - Support cleaning and scanning SWIG-generated files.
4725 - Allow selection of Visual Studio version by setting $MSVS_VERSION
4726 after construction environment initialization.
4728 From Jean-Baptiste Lab:
4730 - Try using zipimport if we can't import Tool or Platform modules
4731 using the normal "imp" module. This allows SCons to be packaged
4732 using py2exe's all-in-one-zip-file approach.
4736 - Do not re-scan files if the scanner returns no implicit dependencies.
4738 From Sanjoy Mahajan:
4740 - Change use of $SOURCES to $SOURCE in all TeX-related Tool modules.
4742 From Joel B. Mohler:
4744 - Make SCons aware that "\makeindex" in TeX source files means that
4745 related .ilg, .ind and .idx index files will be created.
4746 (NOTE: This still needs to search for the string in \include files.)
4748 - Prevent scanning the TeX .aux file for additional files from
4749 trying to remove it twice when the -c option is used.
4751 From Leanid Nazdrynau:
4753 - Give the MSVC RES (resource) Builder a src_builder list and a .rc
4754 src_suffix so other builders can generate .rc files.
4756 From Matthew A. Nicholson:
4758 - Enhance Install() and InstallAs() to handle directory trees as sources.
4762 - Don't use the -fPIC flag when using gcc on Windows (e.g. MinGW).
4766 - Add an env.ParseFlags() method that provides separate logic for
4767 parsing GNU tool chain flags into a dictionary.
4769 - Add an env.MergeFlags() method to apply an arbitrary dictionary
4770 of flags to a construction environment's variables.
4772 From Gary Oberbrunner:
4774 - Fix parsing tripartite Intel C compiler version numbers on Linux.
4776 - Extend the ParseConfig() function to recognize -arch and
4779 - Have the error message list the known suffixes when a Builder call
4780 can't build a source file with an unknown suffix.
4782 From Karol Pietrzak:
4784 - Avoid recursive calls to main() in the program snippet used by the
4785 SConf subsystem to test linking against libraries. This changes the
4786 default behavior of CheckLib() and CheckLibWithHeader() to print
4787 "Checking for C library foo..." instead of "Checking for main()
4788 in C library foo...".
4792 - Throw an exception if a command called by ParseConfig() or
4793 ParseFlags() returns an error.
4795 From Stefan Seefeld:
4797 - Initial infrastructure for running SCons tests under QMTest.
4801 - Fix tests that fail due to gcc warnings.
4803 From Dobes Vandermeer:
4805 - In stack traces, print the full paths of SConscript files.
4809 - Fix detection of Visual C++ Express Edition.
4811 From Dobes Vandermeer:
4813 - Let the src_dir option to the SConscript() function affect all the
4814 the source file paths, instead of treating all source files paths
4815 as relative to the SConscript directory itself.
4817 From Nicolas Vigier:
4819 - Fix finding Fortran modules in build directories.
4821 - Fix use of BuildDir() when the source file in the source directory
4822 is a symlink with a relative path.
4826 - Fix the Memoizer when the SCons Python modules are executed from
4827 .pyo files at different locations from where they were compiled.
4831 - Fix missing os.path.join() when constructing the $FRAMEWORKSDKDIR/bin.
4835 RELEASE 0.96.92 - Mon, 10 Apr 2006 21:08:22 -0400
4837 NOTE: This was a pre-release of 0.97 for testing purposes.
4841 - Fix the intelc.py Tool module to not throw an exception if the
4842 only installed version is something other than ia32.
4844 - Set $CCVERSION when using gcc.
4848 - Support generating project and solution files for Microsoft
4849 Visual Studio version 8.
4851 - Support generating more than one project file for a Microsoft
4852 Visual Studio solution file.
4854 - Add support for a support "runfile" parameter to Microsoft
4855 Visual Studio project file creation.
4857 - Put the project GUID, not the solution GUID, in the right spot
4858 in the solution file.
4860 From Erling Andersen:
4862 - Fix interpretation of Node.FS objects wrapped in Proxy instances,
4863 allowing expansion of things like ${File(TARGET)} in command lines.
4865 From Stanislav Baranov:
4867 - Add a separate MSVSSolution() Builder, with support for the
4868 following new construction variables: $MSVSBUILDCOM, $MSVSCLEANCOM,
4869 $MSVSENCODING, $MSVSREBUILDCOM, $MSVSSCONS, $MSVSSCONSCOM,
4870 $MSVSSCONSFLAGS, $MSVSSCONSCRIPT and $MSVSSOLUTIONCOM.
4872 From Ralph W. Grosse-Kunstleve and Patrick Mezard:
4874 - Remove unneceesary (and incorrect) SCons.Util strings on some function
4875 calls in SCons.Util.
4879 - Fix C/C++ compiler selection on AIX to not always use the external $CC
4880 environment variable.
4882 From August Hörandl:
4884 - Add a scanner for \include and \import files, with support for
4885 searching a directory list in $TEXINPUTS (imported from the external
4888 - Support $MAKEINDEX, $MAKEINDEXCOM, $MAKEINDEXCOMSTR and
4889 $MAKEINDEXFLAGS for generating indices from .idx files.
4891 From Steven Johnson:
4893 - Add a NoClean() Environment method and function to override removal
4894 of targets during a -c clean, including documentation and tests.
4898 - Check for whether files exist on disk by listing the directory
4899 contents, not calling os.path.exists() file by file. This is
4900 somewhat more efficient in general, and may be significantly
4901 more efficient on Windows.
4903 - Minor speedups in the internal is_Dict(), is_List() and is_String()
4906 - Fix a signature refactoring bug that caused Qt header files to
4907 get re-generated every time.
4909 - Don't fail when writing signatures if the .sconsign.dblite file is
4910 owned by a different user (e.g. root) from a previous run.
4912 - When deleting variables from stacked OverrideEnvironments, don't
4913 throw a KeyError if we were able to delte the variable from any
4914 Environment in the stack.
4916 - Get rid of the last indentation tabs in the SCons source files and
4917 add -tt to the Python invocations in the packaging build and the
4918 tests so they don't creep back in.
4920 - In Visual Studio project files, put quotes around the -C directory
4921 so everything works even if the path has spaces in it.
4923 - The Intel Fortran compiler uses -object:$TARGET, not "-o $TARGET",
4924 when building object files on Windows. Have the the ifort Tool
4925 modify the default command lines appropriately.
4927 - Document the --debug=explain option in the man page. (How did we
4930 - Add a $LATEXRETRIES variable to allow configuration of the number of
4931 times LaTex can be re-called to try to resolve undefined references.
4933 - Change the order of the arguments to Configure.Checklib() to match
4936 - Handle signature calculation properly when the Python function used
4937 for a FunctionAction is an object method.
4939 - On Windows, assume that absolute path names without a drive letter
4940 refer to the drive on which the SConstruct file lives.
4942 - Add /usr/ccs/bin to the end of the the default external execution
4945 - Add $PKGCHK and $PKGINFO variables for use on Solaris when searching
4946 for the SunPRO C++ compiler. Make the default value for $PKGCHK
4947 be /usr/sbin/pgkchk (since /usr/sbin isn't usually on the external
4950 - Fix a man page example of overriding variables when calling
4951 SharedLibrary() to also set the $LIBSUFFIXES variable.
4953 - Add a --taskmastertrace=FILE option to give some insight on how
4954 the taskmaster decides what Node to build next.
4956 - Changed the names of the old $WIN32DEFPREFIX, $WIN32DEFSUFFIX,
4957 $WIN32DLLPREFIX and $WIN32IMPLIBPREFIX construction variables to
4958 new $WINDOWSDEFPREFIX, $WINDOWSDEFSUFFIX, $WINDOWSDLLPREFIX and
4959 $WINDOWSIMPLIBPREFIX construction variables. The old names are now
4960 deprecated, but preserved for backwards compatibility.
4962 - Fix (?) a runtest.py hang on Windows when the --xml option is used.
4964 - Change the message when an error occurs trying to interact with the
4965 file system to report the target(s) in square brackets (as before) and
4966 the actual file or directory that encountered the error afterwards.
4970 - Add x64 support for Microsoft Visual Studio 8.
4972 From Baptiste Lepilleur:
4974 - Support the --debug=memory option on Windows when the Python version
4975 has the win32process and win32api modules.
4977 - Add support for Visual Studio 2005 Pro.
4979 - Fix portability issues in various tests: test/Case.py,
4980 Test/Java/{JAR,JARCHDIR,JARFLAGS,JAVAC,JAVACFLAGS,JAVAH,RMIC}.py,
4981 test/MSVS/vs-{6.0,7.0,7.1,8.0}-exec.py,
4982 test/Repository/{Java,JavaH,RMIC}.py,
4983 test/QT/{generated-ui,installed,up-to-date,warnings}.py,
4986 - Ignore pkgchk errors on Solaris when searching for the C++ compiler.
4988 - Speed up the SCons/EnvironmentTests.py unit tests.
4990 - Add a --verbose= option to runtest.py to print executed commands
4991 and their output at various levels.
4993 From Christian Maaser:
4995 - Add support for Visual Studio Express Editions.
4997 - Add support for Visual Studio 8 *.manifest files, includng
4998 new $WINDOWS_INSERT_MANIFEST, $WINDOWSPROGMANIFESTSUFFIX,
4999 $WINDOWSPROGMANIFESTPREFIX, $WINDOWSPROGMANIFESTSUFFIX,
5000 $WINDOWSSHLIBMANIFESTPREFIX and $WINDOWSSHLIBMANIFESTSUFFIX
5001 construction variables.
5005 - Fix detection of additional Java inner classes following use of a
5006 "new" keyword inside an inner class.
5008 From Sanjoy Mahajan:
5010 - Correct TeX-related command lines to just $SOURCE, not $SOURCES
5012 From Patrick Mezard:
5014 - Execute build commands for a command-line target if any of the
5015 files built along with the target is out of date or non-existent,
5016 not just if the command-line target itself is out of date.
5018 - Fix the -n option when used with -c to print all of the targets
5019 that will be removed for a multi-target Builder call.
5021 - If there's no file in the source directory, make sure there isn't
5022 one in the build directory, too, to avoid dangling files left
5023 over from previous runs when a source file is removed.
5025 - Allow AppendUnique() and PrependUnique() to append strings (and
5026 other atomic objects) to lists.
5028 From Joel B. Mohler:
5030 - Extend latex.py, pdflatex.py, pdftex.py and tex.py so that building
5031 from both TeX and LaTeX files uses the same logic to call $BIBTEX
5032 when it's necessary, to call $MAKEINDEX when it's necessary, and to
5033 call $TEX or $LATEX multiple times to handle undefined references.
5035 - Add an emitter to the various TeX builders so that the generated
5036 .aux and .log files also get deleted by the -c option.
5038 From Leanid Nazdrynau:
5040 - Fix the Qt UIC scanner to work with generated .ui files (by using
5041 the FindFile() function instead of checking by-hand for the file).
5043 From Jan Nieuwenhuizen:
5045 - Fix a problem with interpreting quoted argument lists on command lines.
5049 - Add /sw/bin to the default execution PATH on Mac OS X.
5053 - When building a .jar file and there is a $JARCHDIR, put the -C
5054 in front of each .class file on the command line.
5056 - Recognize the Java 1.5 enum keyword.
5058 From Asfand Yar Qazi:
5060 - Add /opt/bin to the default execution PATH on all POSIX platforms
5061 (between /usr/local/bin and /bin).
5065 - Fix the use of Configure() contexts from nested subsidiary
5068 From Christoph Schulz:
5070 - Add support for $CONFIGUREDIR and $CONFIGURELOG variables to control
5071 the directory and logs for configuration tests.
5073 - Add support for a $INSTALLSTR variable.
5075 - Add support for $RANLIBCOM and $RANLIBCOMSTR variables (which fixes
5076 a bug when setting $ARCOMSTR).
5080 - Add use of $CPPDEFINES to $RCCOM (resource file compilation) on MinGW.
5082 From Erick Tryzelaar:
5084 - Fix the error message when trying to report that a given option is
5085 not gettable/settable from an SConscript file.
5087 From Dobes Vandermeer:
5089 - Add support for SCC and other settings in Microsoft Visual
5090 Studio project and solution files: $MSVS_PROJECT_BASE_PATH,
5091 $MSVS_PROJECT_GUID, $MSVS_SCC_AUX_PATH, $MSVS_SCC_LOCAL_PATH,
5092 $MSVS_SCC_PROJECT_NAME, $MSVS_SCC_PROVIDER,
5094 - Add support for using a $SCONS_HOME variable (imported from the
5095 external environment, or settable internally) to put a shortened
5096 SCons execution line in the Visual Studio project file.
5098 From David J. Van Maren:
5100 - Only filter common prefixes from source files names in Visual Studio
5101 project files if the prefix is a complete (sub)directory name.
5105 - If $MSVSVERSIONS is already set, don't overwrite it with
5106 information from the registry.
5110 RELEASE 0.96.91 - Thu, 08 Sep 2005 07:18:23 -0400
5112 NOTE: This was a pre-release of 0.97 for testing purposes.
5116 - Have the environment store the toolpath and re-use it to find Tools
5117 modules during later Copy() or Tool() calls (unless overridden).
5119 - Normalize the directory path names in SConsignFile() database
5120 files so the same signature file can interoperate on Windows and
5121 non-Windows systems.
5123 - Make --debug=stacktrace print a stacktrace when a UserError is thrown.
5125 - Remove an old, erroneous cut-and-paste comment in Scanner/Dir.py.
5127 From Stanislav Baranov:
5129 - Make it possible to support with custom Alias (sub-)classes.
5131 - Allow Builders to take empty source lists when called.
5133 - Allow access to both TARGET and SOURCE in $*PATH expansions.
5135 - Allow SConscript files to modify BUILD_TARGETS.
5137 From Timothee Besset:
5139 - Add support for Objective C/C++ .m and .mm file suffixes (for
5144 - Fix the PharLap linkloc.py module to use target+source arguments
5145 when calling env.subst().
5147 From Bjorn Eriksson:
5149 - Fix an incorrect Command() keyword argument in the man page.
5151 - Add a $TEMPFILEPREFIX variable to control the prefix or flag used
5152 to pass a long-command-line-execution tempfile to a command.
5156 - Enhanced the SCons setup.py script to install man pages on
5159 - Add support for an Options.FormatOptionHelpText() method that can
5160 be overridden to customize the format of Options help text.
5162 - Add a global name for the Entry class (which had already been
5165 - Fix re-scanning of generated source files for implicit dependencies
5166 when the -j option is used.
5168 - Fix a dependency problem that caused $LIBS scans to not be added
5169 to all of the targets in a multiple-target builder call, which
5170 could cause out-of-order builds when the -j option is used.
5172 - Store the paths of source files and dependencies in the .sconsign*
5173 file(s) relative to the target's directory, not relative to the
5174 top-level SConstruct directory. This starts to make it possible to
5175 subdivide the dependency tree arbitrarily by putting an SConstruct
5176 file in every directory and using content signatures.
5178 - Add support for $YACCHFILESUFFIX and $YACCHXXFILESUFFIX variables
5179 that accomodate parser generators that write header files to a
5180 different suffix than the hard-coded .hpp when the -d option is used.
5182 - The default behavior is now to store signature information in a
5183 single .sconsign.dblite file in the top-level SConstruct directory.
5184 The old behavior of a separate .sconsign file in each directory can
5185 be specified by calling SConsignFile(None).
5187 - Remove line number byte codes within the signature calculation
5188 of Python function actions, so that changing the location of an
5189 otherwise unmodified Python function doesn't cause rebuilds.
5191 - Fix AddPreAction() and AddPostAction() when an action has more than
5192 one target file: attach the actions to the Executor, not the Node.
5194 - Allow the source directory of a BuildDir / build_dir to be outside
5195 of the top-level SConstruct directory tree.
5197 - Add a --debug=nomemoizer option that disables the Memoizer for clearer
5198 looks at the counts and profiles of the underlying function calls,
5199 not the Memoizer wrappers.
5201 - Print various --debug= stats even if we exit early (e.g. using -h).
5203 - Really only use the cached content signature value if the file
5204 is older than --max-drift, not just if --max-drift is set.
5206 - Remove support for conversion from old (pre 0.96) .sconsign formats.
5208 - Add support for a --diskcheck option to enable or disable various
5209 on-disk checks: that File and Dir nodes match on-disk entries;
5210 whether an RCS file exists for a missing source file; whether an
5211 SCCS file exists for a missing source file.
5213 - Add a --raw argument to the sconsign script, so it can print a
5214 raw representation of each entry's NodeInfo dictionary.
5216 - Add the 'f90' and 'f95' tools to the list of Fortran compilers
5217 searched for by default.
5219 - Add the +Z option by default when compiling shared objects on
5224 - Handle Visual Studio project and solution files in Unicode.
5226 From Sanjoy Mahajan:
5228 - Fix a bad use of Copy() in an example in the man page, and a
5229 bad regular expression example in the man page and User's Guide.
5233 - Have the Visual Studio project file(s) echo "Starting SCons" before
5234 executing SCons, mainly to work around a quote-stripping bug in
5235 (some versions of?) the Windows cmd command executor.
5237 From Georg Mischler:
5239 - Remove the space after the -o option when invoking the Borland
5240 BCC compiler; some versions apparently require that the file name
5241 argument be concatenated with the option.
5243 From Leanid Nazdrynau:
5245 - Fix the Java parser's handling of backslashes in strings.
5249 - Add construction variables to support frameworks on Mac OS X:
5250 $FRAMEWORKS, $FRAMEWORKPREFIX, $FRAMEWORKPATH, $FRAMEWORKPATHPREFIX.
5252 - Re-order link lines so the -o option always comes right after the
5255 From Gary Oberbrunner:
5257 - Add support for Intel C++ beta 9.0 (both 32 and 64 bit versions).
5259 - Document the new $FRAMEWORK* variables for Mac OS X.
5261 From Karol Pietrzak:
5263 - Add $RPATH (-R) support to the Sun linker Tool (sunlink).
5265 - Add a description of env.subst() to the man page.
5269 - Look in the right directory, not always the local directory, for a
5270 same-named file or directory conflict on disk.
5272 - On Windows, preserve the external environment's %SYSTEMDRIVE%
5277 - Have the Fortran module emitter look for Fortan modules to be created
5278 relative to $FORTRANMODDIR, not the top-level directory.
5280 - When saving Options to a file, run default values through the
5281 converter before comparing them with the set values. This correctly
5282 suppresses Boolean Option values from getting written to the saved
5283 file when they're one of the many synonyms for a default True or
5286 - Fix the Fortran Scanner's ability to handle a module being used
5287 in the same file in which it is defined.
5291 - Add the -KPIC option by default when compiling shared objects on
5294 - Change the default suffix for Solaris objects to .o, to conform to
5295 Sun WorkShop's expectations. Change the profix to so_ so they can
5296 still be differentiated from static objects in the same directory.
5300 - When calling the resource compiler on MinGW, add --include-dir and
5301 the source directory so it finds the source file.
5303 - Update EnsureSConsVersion() to support revision numbers.
5307 - Fix a misplaced line in the man page.
5311 RELEASE 0.96.90 - Tue, 15 Feb 2005 21:21:12 +0000
5313 NOTE: This was a pre-release of 0.97 for testing purposes.
5317 - Fix Java parsing to avoid erroneously identifying a new array
5318 of class instances as an anonymous inner class.
5320 - Fix a typo in the man page description of PathIsDirCreate.
5324 - Allow Help() to be called multiple times, appending to the help
5327 - Allow Tools found on a toolpath to import Python modules from
5328 their local directory.
5330 From Steve Christensen:
5332 - Handle exceptions from Python functions as build actions.
5334 - Add a set of canned PathOption validators: PathExists (the default),
5335 PathIsFile, PathIsDir and PathIsDirCreate.
5339 - Add support for .lex and .yacc file suffixes for Lex and Yacc files.
5343 - Huge performance improvement: wrap the tuples representing an
5344 include path in an object, so that the time it takes to hash the
5345 path doesn't grow porportionally to the length of the path.
5347 From Gottfried Ganssauge:
5349 - Fix SCons on SuSE/AMD-64 Linux by having the wrapper script also
5350 check for the build engine in the parent directory of the Python
5351 library directory (/usr/lib64 instead of /usr/lib).
5353 From Stephen Kennedy:
5355 - Speed up writing the .sconsign file at the end of a run by only
5356 calling sync() once at the end, not after every entry.
5360 - When compiling with Microsoft Visual Studio, don't include the ATL and
5361 MFC directories in the default INCLUDE and LIB environment variables.
5363 - Remove the following deprecated features: the ParseConfig()
5364 global function (deprecated in 0.93); the misspelled "validater"
5365 keyword to the Options.Add() method (deprecated in 0.91); the
5366 SetBuildSignatureType(), SetContentSignatureType(), SetJobs() and
5367 GetJobs() global functions (deprecated in 0.14).
5369 - Fix problems with corrupting the .sconsign.dblite file when
5370 interrupting builds by writing to a temporary file and renaming,
5371 not writing the file directly.
5373 - Fix a 0.96 regression where when running with -k, targets built from
5374 walking dependencies later on the command line would not realize
5375 that a dependency had failed an earlier build attempt, and would
5376 try to rebuild the dependent targets.
5378 - Change the final messages when using -k and errors occur from
5379 "{building,cleaning} terminated because of errors" to "done
5380 {building,cleaning} targets (errors occurred during {build,clean})."
5382 - Allow Configure.CheckFunc() to take an optional header argument
5383 (already supported by Conftest.py) to specify text at the top of
5384 the compiled test file.
5386 - Fix the --debug=explain output when a Python function action changed
5387 so it prints a meaningful string, not the binary representation of
5388 the function contents.
5390 - Allow a ListOption's default value(s) to be a Python list of specified
5391 values, not just a string containing a comma-separated list of names.
5393 - Add a ParseDepends() function that will parse up a list of explicit
5394 dependencies from a "make depend" style file.
5396 - Support the ability to change directory when executing an Action
5397 through "chdir" keyword arguments to Action and Builder creation
5400 - Fix handling of Action ojects (and other callables that don't match
5401 our calling arguments) in construction variable expansions.
5403 - On Win32, install scons.bat in the Python directory when installing
5404 from setup.py. (The bdist_wininst installer was already doing this.)
5406 - Fix env.SConscript() when called with a list of SConscipt files.
5407 (The SConscript() global function already worked properly.)
5409 - Add a missing newline to the end of the --debug=explain "unknown
5412 - Enhance ParseConfig() to work properly for spaces in between the -I,
5413 -L and -l options and their arguments.
5415 - Packaging build fix: Rebuild the files that are use to report the
5416 --version of SCons whenever the development version number changes.
5418 - Fix the ability to specify a target_factory of Dir() to a Builder,
5419 which the default create-a-directory Builder was interfering with.
5421 - Mark a directory as built if it's created as part of the preparation
5422 for another target, to avoid trying to build it again when it comes
5423 up in the target list.
5425 - Allow a function with the right calling signature to be put directly
5426 in an Environment's BUILDERS dictionary, making for easier creation
5427 and use of wrappers (pseudo-Builders) that call other Builders.
5429 - On Python 2.x, wrap lists of Nodes returned by Builders in a UserList
5430 object that adds a method that makes str() object return a string
5431 with all of the Nodes expanded to their path names. (Builders under
5432 Python 1.5.2 still return lists to avoid TypeErrors when trying
5433 to extend() list, so Python 1.5.2 doesn't get pretty-printing of Node
5434 lists, but everything should still function.)
5436 - Allow Aliases to have actions that will be executed whenever
5437 any of the expanded Alias targets are out of date.
5439 - Fix expansion of env.Command() overrides within target and
5442 - Support easier customization of what's displayed by various default
5443 actions by adding lots of new construction variables: $ARCOMSTR,
5444 $ASCOMSTR, $ASPPCOMSTR, $BIBTEXCOMSTR, $BITKEEPERCOMSTR, $CCCOMSTR,
5445 $CVSCOMSTR, $CXXCOMSTR, $DCOMSTR, $DVIPDFCOMSTR, $F77COMSTR,
5446 $F90COMSTR, $F95COMSTR, $FORTRANCOMSTR, $GSCOMSTR, $JARCOMSTR,
5447 $JAVACCOMSTR, $JAVAHCOMSTR, $LATEXCOMSTR, $LEXCOMSTR, $LINKCOMSTR,
5448 $M4COMSTR, $MIDLCOMSTR, $P4COMSTR, $PCHCOMSTR, $PDFLATEXCOMSTR,
5449 $PDFTEXCOMSTR, $PSCOMSTR, $QT_MOCFROMCXXCOMSTR, $QT_MOCFROMHCOMSTR,
5450 $QT_UICCOMSTR, $RCCOMSTR, $REGSVRCOMSTR, $RCS_COCOMSTR, $RMICCOMSTR,
5451 $SCCSCOMSTR, $SHCCCOMSTR, $SHCXXCOMSTR, $SHF77COMSTR, $SHF90COMSTR,
5452 $SHF95COMSTR, $SHFORTRANCOMSTR, $SHLINKCOMSTR, $SWIGCOMSTR,
5453 $TARCOMSTR, $TEXCOMSTR, $YACCCOMSTR and $ZIPCOMSTR.
5455 - Add an optional "map" keyword argument to ListOption() that takes a
5456 dictionary to map user-specified values to legal values from the list
5457 (like EnumOption() already doee).
5459 - Add specific exceptions to try:-except: blocks without any listed,
5460 so that they won't catch and mask keyboard interrupts.
5462 - Make --debug={tree,dtree,stree} print something even when there's
5465 - Fix how Scanners sort the found dependencies so that it doesn't
5466 matter whether the dependency file is in a Repository or not.
5467 This may cause recompilations upon upgrade to this version.
5469 - Make AlwaysBuild() work with Alias and Python value Nodes (making
5470 it much simpler to support aliases like "clean" that just invoke
5471 an arbitrary action).
5473 - Have env.ParseConfig() use AppendUnique() by default to suppress
5474 duplicate entries from multiple calls. Add a "unique" keyword
5475 argument to allow the old behavior to be specified.
5477 - Allow the library modules imported by an SConscript file to get at
5478 all of the normally-available global functions and variables by saying
5479 "from SCons.Script import *".
5481 - Add a --debug=memoizer option to print Memoizer hit/mass statistics.
5483 - Allow more than one --debug= option to be set at a time.
5485 - Change --debug=count to report object counts before and after
5486 reading SConscript files and before and after building targets.
5488 - Change --debug=memory output to line up the numbers and to better
5489 match (more or less) the headers on the --debug=count columns.
5491 - Speed things up when there are lists of targets and/or sources by
5492 getting rid of some N^2 walks of the lists involved.
5494 - Cache evaluation of LazyActions so we don't create a new object
5495 for each invocation.
5497 - When scanning, don't create Nodes for include files that don't
5498 actually exist on disk.
5500 - Make supported global variables CScanner, DScanner, ProgramScanner and
5501 SourceFileScanner. Make SourceFileScanner.add_scanner() a supported
5502 part of the public interface. Keep the old SCons.Defaults.*Scan names
5503 around for a while longer since some people were already using them.
5505 - By default, don't scan directories for on-disk files. Add a
5506 DirScanner global scanner that can be used in Builders or Command()
5507 calls that want source directory trees scanned for on-disk changes.
5508 Have the Tar() and Zip() Builders use the new DirScanner to preserve
5509 the behavior of rebuilding a .tar or .zip file if any file or
5510 directory under a source tree changes. Add Command() support for
5511 a source_scanner keyword argument to Command() that can be set to
5512 DirScanner to get this behavior.
5514 - Documentation changes: Explain that $CXXFLAGS contains $CCFLAGS
5515 by default. Fix a bad target_factory example in the man page.
5516 Add appendices to the User's Guide to cover the available Tools,
5517 Builders and construction variables. Comment out the build of
5518 the old Python 10 paper, which doesn't build on all systems and
5519 is old enough at this point that it probably isn't worth the
5520 effort to make it do so.
5524 - Avoid "maximum recursion limit" errors when removing $(-$) pairs
5525 from long command lines.
5527 From Clive Levinson:
5529 - Make ParseConfig() recognize and add -mno-cygwin to $LINKFLAGS and
5530 $CCFLAGS, and -mwindows to $LINKFLAGS.
5532 From Michael McCracken:
5534 - Add a new "applelink" tool to handle the things like Frameworks and
5535 bundles that Apple has added to gcc for linking.
5537 - Use more appropriate default search lists of linkers, compilers and
5538 and other tools for the 'darwin' platform.
5540 - Add a LoadableModule Builder that builds a bundle on Mac OS X (Darwin)
5541 and a shared library on other systems.
5543 - Improve SWIG tests for use on Mac OS X (Darwin).
5547 - Enhance the tests to guarantee persistence of ListOption
5548 values in saved options files.
5550 - Supply the help text when -h is used with the -u, -U or -D options.
5552 From Christian Neeb:
5554 - Fix the Java parser's handling of string definitions to avoid ignoring
5557 From Han-Wen Nienhuys:
5559 - Optimize variable expansion by: using the re.sub() method (when
5560 possible); not using "eval" for variables for which we can fetch the
5561 value directory; avoiding slowing substitution logic when there's no
5564 From Gary Oberbrunner:
5566 - Add an Environment.Dump() method to print the contents of a
5567 construction environment.
5569 - Allow $LIBS (and similar variables) to contain explicit File Nodes.
5571 - Change ParseConfig to add the found library names directly to the
5572 $LIBS variable, instead of returning them.
5574 - Add ParseConfig() support for the -framework GNU linker option.
5576 - Add a PRINT_CMD_LINE_FUNC construction variable to allow people
5577 to filter (or log) command-line output.
5579 - Print an internal Python stack trace in response to an otherwise
5580 unexplained error when --debug=stacktrace is specified.
5582 - Add a --debug=findlibs option to print what's happening when
5583 the scanner is searching for libraries.
5585 - Allow Tool specifications to be passed a dictionary of keyword
5588 - Support an Options default value of None, in which case the variable
5589 will not be added to the construction environment unless it's set
5590 explicitly by the user or from an Options file.
5592 - Avoid copying __builtin__ values into a construction environment's
5593 dictionary when evaluating construction variables.
5595 - Add a new cross-platform intelc.py Tool that can detect and
5596 configure the Intel C++ v8 compiler on both Windows, where it's
5597 named icl, and Linux, where it's named icc. It also checks that
5598 the directory specified in the Windows registry exists, and sets a
5599 new $INTEL_C_COMPILER_VERSION construction variable to identify the
5600 version being used. (Niall Douglas contributed an early prototype
5601 of parts of this module.)
5603 - Fix the private Conftest._Have() function so it doesn't change
5604 non-alphanumeric characters to underscores.
5606 - Supply a better error message when a construction variable expansion
5607 has an unknown attribute.
5609 - Documentation changes: Update the man page to describe use of
5610 filenames or Nodes in $LIBS.
5614 - Have the linkloc tool use $MSVS_VERSION to select the Microsoft
5615 Visual Studio version to use.
5619 - Fix the Builder name returned from ListBuilders and other instances
5620 of subclasses of the BuilderBase class.
5622 - Add Builders and construction variables to support rpcgen:
5623 RPCGenClient(), RPCGenHeader(), RPCGenService(), RPCGenXDR(),
5624 $RPCGEN, $RPCGENFLAGS, $RPCGENCLIENTFLAGS, $RPCGENHEADERFLAGS,
5625 $RPCGENSERVICEFLAGS, $RPCGENXDRFLAGS.
5627 - Update the man page to document that prefix and suffix Builder
5628 keyword arguments can be strings, callables or dictionaries.
5630 - Provide more info in the error message when a user tries to build
5631 a target multiple ways.
5633 - Fix Delete() when a file doesn't exist and must_exist=1. (We were
5634 unintentionally dependent on a bug in versions of the Python shutil.py
5635 module prior to Python 2.3, which would generate an exception for
5636 a nonexistent file even when ignore_errors was set.)
5638 - Only replace a Node's builder with a non-null source builder.
5640 - Fix a stack trace when a suffix selection dictionary is passed
5641 an empty source file list.
5643 - Allow optional names to be attached to Builders, for default
5644 Builders that don't get attached to construction environments.
5646 - Fix problems with Parallel Task Exception handling.
5648 - Build targets in an associated BuildDir even if there are targets
5649 or subdirectories locally in the source directory.
5651 - If a FunctionAction has a callable class as its underlying Python
5652 function, use its strfunction() method (if any) to display the
5655 - Fix handling when BuildDir() exists but is unwriteable. Add
5656 "Stop." to those error messages for consistency.
5658 - Catch incidents of bad builder creation (without an action) and
5659 supply meaningful error messages.
5661 - Fix handling of src_suffix values that aren't extensions (don't
5664 - Don't retrieve files from a CacheDir, but report what would happen,
5665 when the -n option is used.
5667 - Use the source_scanner from the target Node, not the source node
5670 - Internal Scanners fixes: Make sure Scanners are only passed Nodes.
5671 Fix how a Scanner.Selector called its base class initialization.
5672 Make comparisons of Scanner objects more robust. Add a name to
5673 an internal default ObjSourceScanner.
5675 - Add a deprecated warning for use of the old "scanner" keyword argument
5676 to Builder creation.
5678 - Improve the --debug=explain message when the build action changes.
5680 - Test enhancements in SourceCode.py, option-n.py, midl.py. Better
5681 Command() and Scanner test coverage. Improved test infrastructure
5684 - Refactor the interface between Action and Executor objects to treat
5687 - The --debug=presub option will now report the pre-substitution
5688 each action seprately, instead of reporting the entire list before
5689 executing the actions one by one.
5691 - The --debug=explain option explaining a changed action will now
5692 (more correctly) show pre-substitution action strings, instead of
5693 the commands with substituted file names.
5695 - A Node (file) will now be rebuilt if its PreAction or PostAction
5698 - Python Function actions now have their calling signature (target,
5699 source, env) reported correctly when displayed.
5701 - Fix BuildDir()/build_dir handling when the build_dir is underneath
5702 the source directory and trying to use entries from the build_dir
5703 as sources for other targets in the build-dir.
5705 - Fix hard-coding of JDK path names in various Java tests.
5707 - Handle Python stack traces consistently (stop at the SConscript stack
5708 frame, by default) even if the Python source code isn't available.
5710 - Improve the performance of the --debug={tree,dtree} options.
5712 - Add --debug=objects logging of creation of OverrideWarner,
5713 EnvironmentCopy and EnvironmentOverride objects.
5715 - Fix command-line expansion of Python Value Nodes.
5717 - Internal cleanups: Remove an unnecessary scan argument. Associate
5718 Scanners only with Builders, not nodes. Apply overrides once when
5719 a Builder is called, not in multiple places. Cache results from the
5720 Node.FS.get_suffix() and Node.get_build_env() methods. Use the Python
5721 md5 modules' hexdigest() method, if there is one. Have Taskmaster
5722 call get_stat() once for each Node and re-use the value instead of
5723 calling it each time it needs the value. Have Node.depends_on()
5724 re-use the list from the children() method instead of calling it
5727 - Use the correct scanner if the same source file is used for targets in
5728 two different environments with the same path but different scanners.
5730 - Collect logic for caching values in memory in a Memoizer class,
5731 which cleans up a lot of special-case code in various methods and
5732 caches additional values to speed up most configurations.
5734 - Add a PathAccept validator to the list of new canned PathOption
5739 - Documentation changes: Use $CPPDEFINES instead of $CCFLAGS in man
5744 - Allow $JARCHDIR to be expanded to other construction variables.
5746 From Christoph Wiedemann:
5748 - Add an Environment.SetDefault() method that only sets values if
5749 they aren't already set.
5751 - Have the qt.py Tool not override variables already set by the user.
5753 - Add separate $QT_BINPATH, $QT_CPPPATH and $QT_LIBPATH variables
5754 so these can be set individually, instead of being hard-wired
5757 - The %TEMP% and %TMP% external environment variables are now propagated
5758 automatically to the command execution environment on Windows systems.
5760 - A new --config= command-line option allows explicit control of
5761 of when the Configure() tests are run: --config=force forces all
5762 checks to be run, --config=cache uses all previously cached values,
5763 --config=auto (the default) runs tests only when dependency analysis
5764 determines it's necessary.
5766 - The Configure() subsystem can now write a config.h file with values
5767 like HAVE_STDIO_H, HAVE_LIBM, etc.
5769 - The Configure() subsystem now executes its checks silently when the
5770 -Q option is specified.
5772 - The Configure() subsystem now reports if a test result is being
5773 taken from cache, and prints the standard output and error output
5774 of tests even when cached.
5776 - Configure() test results are now reported as "yes" or "no" instead of
5779 - Fixed traceback printing when calling the env.Configure() method
5780 instead of the Configure() global function.
5782 - The Configure() subsystem now caches build failures in a .sconsign
5783 file in the subdirectory, not a .cache file. This may cause
5784 tests to be re-executed the first time after you install 0.97.
5786 - Additional significant internal cleanups in the Configure() subsystem
5789 - Have the Qt Builder make uic-generated files dependent on the .ui.h
5790 file, if one exists.
5792 - Add a test to make sure that SCons source code does not contain
5793 try:-except: blocks that catch all errors, which potentially catch
5794 and mask keyboard interrupts.
5796 - Fix us of TargetSignatures('content') with the SConf subsystem.
5798 From Russell Yanofsky:
5800 - Add support for the Metrowerks Codewarrior compiler and linker
5805 RELEASE 0.96.1 - Mon, 23 Aug 2004 12:55:50 +0000
5807 From Craig Bachelor:
5809 - Handle white space in the executable Python path name within in MSVS
5810 project files by quoting the path.
5812 - Correct the format of a GUID string in a solution (.dsw) file so
5813 MSVS can correctly "build enable" a project.
5817 - Add a must_exist flag to Delete() to let the user control whether
5818 it's an error if the specified entry doesn't exist. The default
5819 behavior is now to silently do nothing if it doesn't exist.
5821 - Package up the new Platform/darwin.py, mistakenly left out of 0.96.
5823 - Make the scons.bat REM statements into @REM so they aren't printed.
5825 - Make the SCons packaging SConscript files platform independent.
5829 - Fix scanning of pre-compiled header (.pch) files for #includes,
5834 RELEASE 0.96 - Wed, 18 Aug 2004 13:36:40 +0000
5838 - Make the CacheDir() directory if it doesn't already exist.
5840 - Allow construction variable substitutions in $LIBS specifications.
5842 - Allow the emitter argument to a Builder() to be or expand to a list
5843 of emitter functions, which will be called in sequence.
5845 - Suppress null values in construction variables like $LIBS that use
5846 the internal _concat() function.
5848 - Remove .dll files from the construction variables searched for
5849 libraries that can be fed to Win32 compilers.
5851 From Chad Austin and Christoph Wiedemann:
5853 - Add support for a $RPATH variable to supply a list of directories
5854 to search for shared libraries when linking a program. Used by
5855 the GNU and IRIX linkers (gnulink and sgilink).
5859 - Restore the ability to do construction variable substitutions in all
5860 kinds of *PATH variables, even when the substitution returns a Node
5865 - Allow the Java() Builder to take more than one source directory.
5867 From Ralf W. Grosse-Kunstleve:
5869 - Have SConsignFile() use, by default, a custom "dblite.py" that we can
5870 control and guarantee to work on all Python versions (or nearly so).
5872 From Jonathan Gurley:
5874 - Add support for the newer "ifort" versions of the Intel Fortran
5879 - Make the new *FLAGS variable type work with copied Environments.
5881 From Chris Hoeppler:
5883 - Initialize the name of a Scanner.Classic scanner correctly.
5887 - Add support for the .dylib shared library suffix and the -dynamiclib
5888 linker option on Mac OS X.
5892 - Add an Execute() method for executing actions directly.
5894 - Support passing environment override keyword arguments to Command().
5896 - Fix use of $MSVS_IGNORE_IDE_PATHS, which was broken when we added
5897 support for $MSVS_USE_MFC_DIRS last release.
5899 - Make env.Append() and env.Prepend() act like the underlying Python
5900 behavior when the variable being appended to is a UserList object.
5902 - Fix a regression that prevented the Command() global function in
5903 0.95 from working with command-line strings as actions.
5905 - Fix checking out a file from a source code management system when
5906 the env.SourceCode() method was called with an individual file name
5907 or node, not a directory name or node.
5909 - Enhance the Task.make_ready() method to create a list of the
5910 out-of-date Nodes for the task for use by the wrapping interface.
5912 - Allow Scanners to pull the list of suffixes from the construction
5913 environment when the "skeys" keyword argument is a string containing
5914 a construction variable to be expanded.
5916 - Support new $CPPSUFFIXES, $DSUFFIXES $FORTRANSUFFIXES, and
5917 $IDLSUFFIXES. construction variables that contain the default list
5918 of suffixes to be scanned by a given type of scanner, allowing these
5919 suffix lists to be easily added to or overridden.
5921 - Speed up Node creation when calling a Builder by comparing whether two
5922 Environments are the same object, not if their underlying dictionaries
5925 - Add a --debug=explain option that reports the reason(s) why SCons
5926 thinks it must rebuild something.
5928 - Add support for functions that return platform-independent Actions
5929 to Chmod(), Copy(), Delete(), Mkdir(), Move() and Touch() files
5930 and/or directories. Like any other Actions, the returned Action
5931 object may be executed directly using the Execute() global function
5932 or env.Execute() environment method, or may be used as a Builder
5933 action or in an env.Command() action list.
5935 - Add support for the strfunction argument to all types of Actions:
5936 CommandAction, ListAction, and CommandGeneratorAction.
5938 - Speed up turning file system Nodes into strings by caching the
5939 values after we're finished reading the SConscript files.
5941 - Have ParseConfig() recognize and supporting adding the -Wa, -Wl,
5942 and -Wp, flags to ASFLAGS, LINKFLAGS and CPPFLAGS, respectively.
5944 - Change the .sconsign format and the checks for whether a Node is
5945 up-to-date to make dependency checks more efficient and correct.
5947 - Add wrapper Actions to SCons.Defaults for $ASCOM, $ASPPCOM, $LINKCOM,
5948 $SHLINKCOM, $ARCOM, $LEXCOM and $YACCCOM. This makes it possible
5949 to replace the default print behavior with a custom strfunction()
5952 - When a Node has been built, don't walk the whole tree back to delete
5953 the parents's implicit dependencies, let returning up the normal
5954 Taskmaster descent take care of it for us.
5956 - Add documented support for separate target_scanner and source_scanner
5957 arguments to Builder creation, which allows different scanners to
5958 be applied to source files
5960 - Don't re-install or (re-generate) .h files when a subsidiary #included
5961 .h file changes. This eliminates incorrect circular dependencies
5962 with .h files generated from other source files.
5964 - Slim down the internal Sig.Calculator class by eliminating methods
5965 whose functionality is now covered by Node methods.
5967 - Document use of the target_factory and source_factory keyword
5968 arguments when creating Builder objects. Enhance Dir Nodes so that
5969 they can be created with user-specified Builder objects.
5971 - Don't blow up with stack trace when the external $PATH environment
5974 - Make Builder calls return lists all the time, even if there's only
5975 one target. This keeps things consistent and easier to program to
5978 - Add a Flatten() function to make it easier to deal with the Builders
5979 all returning lists of targets, not individual targets.
5981 - Performance optimizations in Node.FS.__doLookup().
5983 - Man page fixes: formatting typos, misspellings, bad example.
5985 - User's Guide fixes: Fix the signatures of the various example
5986 *Options() calls. Triple-quote properly a multi-line Split example.
5988 - User's Guide additions: Chapter describing File and Directory
5989 Nodes. Section describing declarative nature of SCons functions in
5990 SConscript files. Better organization and clarification of points
5991 raised by Robert P. J. Day. Chapter describing SConf (Autoconf-like)
5992 functionality. Chapter describing how to install Python and
5993 SCons. Chapter describing Java builds.
5997 - Add a .win32 attribute to force file names to expand with
5998 Windows backslash path separators.
6000 - Fix escaping file names on command lines when the expansion is
6001 concatenated with another string.
6003 - Add support for Fortran 90 and Fortran 95. This adds $FORTRAN*
6004 variables that specify a default compiler, command-line, flags,
6005 etc. for all Fortran versions, plus separate $F90* and $F95*
6006 variables for when different compilers/flags/etc. must be specified
6007 for different Fortran versions.
6009 - Have individual tools that create libraries override the default
6010 $LIBPREFIX and $LIBSUFFIX values set by the platform. This makes
6011 it easier to use Microsoft Visual Studio tools on a CygWin platform.
6013 From Gary Oberbrunner:
6015 - Add a --debug=presub option to print actions prior to substitution.
6017 - Add a warning upon use of the override keywords "targets" and
6018 "sources" when calling Builders. These are usually mistakes which
6019 are otherwise silently (and confusingly) turned into construction
6022 - Try to find the ICL license file path name in the external environment
6023 and the registry before resorting to the hard-coded path name.
6025 - Add support for fetching command-line keyword=value arguments in
6026 order from an ARGLIST list.
6028 - Avoid stack traces when trying to read dangling symlinks.
6030 - Treat file "extensions" that only contain digits as part of the
6031 file basename. This supports version numbers as part of shared
6032 library names, for example.
6034 - Avoid problems when there are null entries (None or '') in tool
6037 - Add an example and explanation of how to use "tools = ['default', ..."
6038 when creating a construction environment.
6040 - Add a section describing File and Directory Nodes and some of their
6041 attributes and methods.
6043 - Have ParseConfig() add a returned -pthread flag to both $CCFLAGS
6046 - Fix some test portability issues on Mac OS X (darwin).
6050 - Fix a bug introduced in building shared libraries under MinGW.
6054 - Handling SCons exceptions according to Pythonic standards.
6056 - Fix test/chained-build.py on systems that execute within one second.
6058 - Fix tests on systems where 'ar' warns about archive creation.
6062 - Fix use of the --implicit-cache option with timestamp signatures.
6064 - If Visual Studio is installed, assume the C/C++ compiler, the linker
6065 and the MIDL compiler that comes with it are available, too.
6067 - Better error messages when evaluating a construction variable
6068 expansion yields a Python syntax error.
6070 - Change the generation of PDB files when using Visual Studio from
6071 compile time to link time.
6075 - Allow SConf.CheckLib() to search a list of libraries, like the
6076 Autoconf AC_SEARCH_LIBS macro.
6078 - Allow the env.WhereIs() method to take a "reject" argument to
6079 let it weed out specific path names.
6081 From Christoph Wiedemann:
6083 - Add new Moc() and Uic() Builders for more explicit control over
6084 Qt builds, plus new construction variables to control them:
6085 $QT_AUTOSCAN, $QT_DEBUG, $QT_MOCCXXPREFIX, $QT_MOCCXXSUFFIX,
6086 $QT_MOCHPREFIX, $QT_MOCHSUFFIX, $QT_UICDECLPREFIX, $QT_UICDECLSUFFIX,
6087 $QT_UICIMPLPREFIX, $QT_UICIMPLSUFFIX and $QT_UISUFFIX.
6089 - Add a new single_source keyword argument for Builders that enforces
6090 a single source file on calls to the Builder.
6094 RELEASE 0.95 - Mon, 08 Mar 2004 06:43:20 -0600
6098 - Replace print statements with calls to sys.stdout.write() so output
6099 lines stay together when -j is used.
6101 - Add portability fixes for a number of tests.
6103 - Accomodate the fact that Cygwin's os.path.normcase() lies about
6104 the underlying system being case-sensitive.
6106 - Fix an incorrect _concat() call in the $RCINCFLAGS definition for
6109 - Fix a problem with the msvc tool with Python versions prior to 2.3.
6111 - Add support for a "toolpath" Tool() and Environment keyword that
6112 allows Tool modules to be found in specified local directories.
6114 - Work around Cygwin Python's silly fiction that it's using a
6115 case-sensitive file system.
6117 - More robust handling of data in VCComponents.dat.
6119 - If the "env" command is available, spawn commands with the more
6120 general "env -" instead of "env -i".
6122 From Kerim Borchaev:
6124 - Fix a typo in a msvc.py's registry lookup: "VCComponents.dat", not
6127 From Chris Burghart:
6129 - Fix the ability to save/restore a PackageOption to a file.
6131 From Steve Christensen:
6133 - Update the MSVS .NET and MSVC 6.0/7.0 path detection.
6135 From David M. Cooke:
6137 - Make the Fortran scanner case-insensitive for the INCLUDE string.
6141 - If no version of MSVC is detected but the tool is specified,
6142 use the MSVC 6.0 paths by default.
6144 - Ignore any "6.1" version of MSVC found in the registry; this is a
6145 phony version number (created by later service packs?) and would
6146 throw off the logic if the user had any non-default paths configure.
6148 - Correctly detect if the user has independently configured the MSVC
6149 "include," "lib" or "path" in the registry and use the appropriate
6150 values. Previously, SCons would only use the values if all three
6151 were set in the registry.
6153 - Make sure side-effect nodes are prepare()d before building their
6154 corresponding target.
6156 - Preserve the ability to call BuildDir() multiple times with the
6157 same target and source directory arguments.
6161 - Add support for the Digital Mars "D" programming language.
6163 From Scott Lystig Fritchie:
6165 - Fix the ability to use a custom _concat() function in the
6166 construction environment when calling _stripixes().
6168 - Make the message about ignoring a missing SConscript file into a
6169 suppressable Warning, not a hard-coded sys.stderr.write().
6171 - If a builder can be called multiple times for a target (because
6172 the sources and overrides are identical, or it's a builder with the
6173 "multi" flag set), allow the builder to be called through multiple
6174 environments so long as the builders have the same signature for
6175 the environments in questions (that is, they're the same action).
6179 - When multiple targets are built by a single action, retrieve all
6180 of them from cache, not just the first target, and exec the build
6181 command if any of the targets isn't present in the cache.
6183 From Zephaniah Hull:
6185 - Fix command-line ARGUMENTS with multiple = in them.
6189 - Fix EnsureSConsVersion() so it checks against the SCons version,
6190 not the Python version, on Pythons with sys.version_info.
6192 - Don't swallow the AttributeError when someone uses an expansion like
6193 $TARGET.bak, so we can supply a more informative error message.
6195 - Fix an odd double-quote escape sequence in the man page.
6197 - Fix looking up a naked drive letter as a directory (Dir('C:')).
6199 - Support using File nodes in the LIBS construction variable.
6201 - Allow the LIBS construction variable to be a single string or File
6202 node, not a list, when only one library is needed.
6204 - Fix typos in the man page: JAVACHDIR => JARCHDIR; add "for_signature"
6205 to the __call__() example in the "Variable Substitution" section.
6207 - Correct error message spellings of "non-existant" to "non-existent."
6209 - When scanning for libraries to link with, don't append $LIBPREFIXES
6210 or $LIBSUFFIXES values to the $LIBS values if they're already present.
6212 - Add a ZIPCOMPRESSION construction variable to control whether the
6213 internal Python action for the Zip Builder compresses the file or
6214 not. The default value is zipfile.ZIP_DEFLATED, which generates
6217 - Refactor construction variable expansion to support recursive
6218 expansion of variables (e.g. CCFLAGS = "$CCFLAGS -g") without going
6219 into an infinite loop. Support this in all construction variable
6220 overrides, as well as when copying Environments.
6222 - Fix calling Configure() from more than one subsidiary SConscript file.
6224 - Fix the env.Action() method so it returns the correct type of
6225 Action for its argument(s).
6227 - Fix specifying .class files as input to JavaH with the .class suffix
6228 when they weren't generated using the Java Builder.
6230 - Make the check for whether all of the objects going into a
6231 SharedLibrary() are shared work even if the object was built in a
6234 - Supply meaningful error messages, not stack traces, if we try to add
6235 a non-Node as a source, dependency, or ignored dependency of a Node.
6237 - Generate MSVS Project files that re-invoke SCons properly regardless
6238 of whether the file was built via scons.bat or scons.py.
6239 (Thanks to Niall Douglas for contributing code and testing.)
6241 - Fix TestCmd.py, runtest.py and specific tests to accomodate being
6242 run from directories whose paths include white space.
6244 - Provide a more useful error message if a construction variable
6245 expansion contains a syntax error during evaluation.
6247 - Fix transparent checkout of implicit dependency files from SCCS
6250 - Added new --debug=count, --debug=memory and --debug=objects options.
6251 --debug=count and --debug=objects only print anything when run
6252 under Python 2.1 or later.
6254 - Deprecate the "overrides" keyword argument to Builder() creation
6255 in favor of using keyword argument values directly (like we do
6256 for builder execution and the like).
6258 - Always use the Builder overrides in substitutions, not just if
6259 there isn't a target-specific environment.
6261 - Add new "rsrcpath" and "rsrcdir" and attributes to $TARGET/$SOURCE,
6262 so Builder command lines can find things in Repository source
6263 directories when using BuildDir.
6265 - Fix the M4 Builder so that it chdirs to the Repository directory
6266 when the input file is in the source directory of a BuildDir.
6268 - Save memory at build time by allowing Nodes to delete their build
6269 environments after they've been built.
6271 - Add AppendUnique() and PrependUnique() Environment methods, which
6272 add values to construction variables like Append() and Prepend()
6273 do, but suppress any duplicate elements in the list.
6275 - Allow the 'qt' tool to still be used successfully from a copied
6276 Environment. The include and library directories previously ended up
6277 having the same string re-appended to the end, yielding an incorrect
6280 - Supply a more descriptive error message when the source for a target
6283 - Initialize all *FLAGS variables with objects do the right thing with
6284 appending flags as strings or lists.
6286 - Make things like ${TARGET.dir} work in *PATH construction variables.
6288 - Allow a $MSVS_USE_MFC_DIRS construction variable to control whether
6289 ATL and MFC directories are included in the default INCLUDE and
6292 - Document the dbm_module argument to the SConsignFile() function.
6296 - Add support for the bcc32, ilink32 and tlib Borland tools.
6300 - Supply an error message if the user tries to configure a BuildDir
6301 for a directory that already has one.
6303 - Remove documentation of the still-unimplemented -e option.
6305 - Add -H help text listing the legal --debug values.
6307 - Don't choke if a construction variable is a non-string value.
6309 - Build Type Libraries in the target directory, not the source
6312 - Add an appendix to the User's Guide showing how to accomplish
6313 various common tasks in Python.
6317 - Add support for Microsoft Visual Studio 2003 (version 7.1).
6319 - Evaluate $MSVSPROJECTSUFFIX and $MSVSSOLUTIONSUFFIX when the Builder
6320 is invoked, not when the tool is initialized.
6322 From Christoph Wiedemann:
6324 - When compiling Qt, make sure the moc_*.cc files are compiled using
6325 the flags from the environment used to specify the target, not
6326 the environment that first has the Qt Builders attached.
6330 RELEASE 0.94 - Fri, 07 Nov 2003 05:29:48 -0600
6332 From Hartmut Goebel:
6334 - Add several new types of canned functions to help create options:
6335 BoolOption(), EnumOption(), ListOption(), PackageOption(),
6340 - Fix use of CPPDEFINES with C++ source files.
6342 - Fix env.Append() when the operand is an object with a __cmp__()
6343 method (like a Scanner instance).
6345 - Fix subclassing the Environment and Scanner classes.
6347 - Add BUILD_TARGETS, COMMAND_LINE_TARGETS and DEFAULT_TARGETS variables.
6351 - SGI fixes: Fix C++ compilation, add a separate Tool/sgic++.py module.
6353 From Gary Oberbrunner:
6355 - Fix how the man page un-indents after examples in some browsers.
6359 - Fix the C and C++ tool specifications for AIX.
6363 RELEASE 0.93 - Thu, 23 Oct 2003 07:26:55 -0500
6367 - On POSIX, execute commands with the more modern os.spawnvpe()
6368 function, if it's available.
6370 - Scan .S, .spp and .SPP files for C preprocessor dependencies.
6372 - Refactor the Job.Parallel() class to use a thread pool without a
6373 condition variable. This improves parallel build performance and
6374 handles keyboard interrupts properly when -j is used.
6378 - Add support for a JARCHDIR variable to control changing to a
6379 directory using the jar -C option.
6381 - Add support for detecting Java manifest files when using jar,
6382 and specifying them using the jar m flag.
6384 - Fix some Python 2.2 specific things in various tool modules.
6386 - Support directories as build sources, so that a rebuild of a target
6387 can be triggered if anything underneath the directory changes.
6389 - Have the scons.bat and scons.py files look for the SCons modules
6390 in site-packages as well.
6392 From Christian Engel:
6394 - Support more flexible inclusion of separate C and C++ compilers.
6396 - Use package management tools on AIX and Solaris to find where
6397 the comilers are installed, and what version they are.
6399 - Add support for CCVERSION and CXXVERSION variables for a number
6400 of C and C++ compilers.
6404 - Add test cases for the new capabilities to run bibtex and to rerun
6407 From Ralf W. Grosse-Kunstleve:
6409 - Accomodate anydbm modules that don't have a sync() method.
6411 - Allow SConsignFile() to take an argument specifying the DBM
6414 From Stephen Kennedy:
6416 - Add support for a configurable global .sconsign.dbm file which
6417 can be used to avoid cluttering each directory with an individual
6422 - Fix (re-)scanning of dependencies in generated or installed
6427 - The -Q option suppressed too many messages; fix it so that it only
6428 suppresses the Reading/Building messages.
6430 - Support #include when there's no space before the opening quote
6433 - Accomodate alphanumeric version strings in EnsurePythonVersion().
6435 - Support arbitrary expansion of construction variables within
6436 file and directory arguments to Builder calls and Environment methods.
6438 - Add Environment-method versions of the following global functions:
6439 Action(), AddPostAction(), AddPreAction(), Alias(), Builder(),
6440 BuildDir(), CacheDir(), Clean(), Configure(), Default(),
6441 EnsurePythonVersion(), EnsureSConsVersion(), Environment(),
6442 Exit(), Export(), FindFile(), GetBuildPath(), GetOption(), Help(),
6443 Import(), Literal(), Local(), Platform(), Repository(), Scanner(),
6444 SConscriptChdir(), SConsignFile(), SetOption(), SourceSignatures(),
6445 Split(), TargetSignatures(), Tool(), Value().
6447 - Add the following global functions that correspond to the same-named
6448 Environment methods: AlwaysBuild(), Command(), Depends(), Ignore(),
6449 Install(), InstallAs(), Precious(), SideEffect() and SourceCode().
6451 - Add the following global functions that correspond to the default
6452 Builder methods supported by SCons: CFile(), CXXFile(), DVI(), Jar(),
6453 Java(), JavaH(), Library(), M4(), MSVSProject(), Object(), PCH(),
6454 PDF(), PostScript(), Program(), RES(), RMIC(), SharedLibrary(),
6455 SharedObject(), StaticLibrary(), StaticObject(), Tar(), TypeLibrary()
6458 - Rearrange the man page to show construction environment methods and
6459 global functions in the same list, and to explain the difference.
6461 - Alphabetize the explanations of the builder methods in the man page.
6463 - Rename the Environment.Environment class to Enviroment.Base.
6464 Allow the wrapping interface to extend an Environment by using its own
6465 subclass of Environment.Base and setting a new Environment.Environment
6466 variable as the calling entry point.
6468 - Deprecate the ParseConfig() global function in favor of a same-named
6469 construction environment method.
6471 - Allow the Environment.WhereIs() method to take explicit path and
6472 pathext arguments (like the underlying SCons.Util.WhereIs() function).
6474 - Remove the long-obsolete {Get,Set}CommandHandler() functions.
6476 - Enhance env.Append() to suppress null values when appropriate.
6478 - Fix ParseConfig() so it works regardless of initial construction
6481 Extend CheckHeader(), CheckCHeader(), CheckCXXHeader() and
6482 CheckLibWithHeader() to accept a list of header files that will be
6483 #included in the test. The last one in the list is assumed to be
6484 the one being checked for. (Prototype code contributed by Gerard
6485 Patel and Niall Douglas).
6487 - Supply a warning when -j is used and threading isn't built in to
6488 the current version of Python.
6490 - First release of the User's Guide (finally, and despite a lot
6491 of things still missing from it...).
6495 - Generalize the action for .tex files so that it will decide whether
6496 a file is TeX or LaTeX, check the .aux output to decide if it should
6497 run bibtex, and check the .log output to re-run LaTeX if needed.
6499 From Bram Moolenaar:
6501 - Split the non-SCons-specific functionality from SConf.py to a new,
6502 re-usable Conftest.py module.
6504 From Gary Oberbrunner:
6506 - Allow a directory to be the target or source or dependency of a
6507 Depends(), Ignore(), Precious() or SideEffect() call.
6511 - Use the %{_mandir} macro when building our RPM package.
6513 From Marko Rauhamaa:
6515 - Have the closing message say "...terminated because of errors" if
6520 - On Win32 systems, only use "rm" to delete files if Cygwin is being
6521 used. ("rm" doesn't understand Win32-format path names.)
6523 From Christoph Wiedemann:
6525 - Fix test/SWIG.py to find the Python include directory in all cases.
6527 - Fix a bug in detection of Qt installed on the local system.
6529 - Support returning Python 2.3 BooleanType values from Configure checks.
6531 - Provide an error message if someone mistakenly tries to call a
6532 Configure check from within a Builder function.
6534 - Support calling a Builder when a Configure context is still open.
6536 - Handle interrupts better by eliminating all try:-except: blocks
6537 which caught any and all exceptions, including KeyboardInterrupt.
6539 - Add a --duplicate= option to control how files are duplicated.
6543 RELEASE 0.92 - Wed, 20 Aug 2003 03:45:28 -0500
6545 From Charles Crain and Gary Oberbrunner:
6547 - Fix Tool import problems with the Intel and PharLap linkers.
6551 - Refactor the DictCmdGenerator class to be a Selector subclass.
6553 - Allow the DefaultEnvironment() function to take arguments and pass
6554 them to instantiation of the default construction environment.
6556 - Update the Debian package so it uses Python 2.2 and more closely
6557 resembles the currently official Debian packaging info.
6561 - When the yacc -d flag is used, take the .h file base name from the
6562 target .c file, not the source (matching what yacc does).
6566 RELEASE 0.91 - Thu, 14 Aug 2003 13:00:44 -0500
6570 - Support specifying a list of tools when calling Environment.Copy().
6572 - Give a Value Nodes a timestamp of the system time when they're
6573 created, so they'll work when using timestamp-based signatures.
6575 - Add a DefaultEnvironment() function that only creates a default
6576 environment on-demand (for fetching source files, e.g.).
6578 - Portability fix for test/M4.py.
6582 - Tighten up the scons -H help output.
6584 - When the input yacc file ends in .yy and the -d flag is specified,
6585 recognize that a .hpp file (not a .h file) will be created.
6587 - Make builder prefixes work correctly when deducing a target
6588 from a source file name in another directory.
6590 - Documentation fixes: typo in the man page; explain up-front about
6591 not propagating the external environment.
6593 - Use "cvs co -d" instead of "cvs co -p >" when checking out something
6594 from CVS with a specified module name. This avoids zero-length
6595 files when there is a checkout error.
6597 - Add an "sconsign" script to print the contents of .sconsign files.
6599 - Speed up maintaining the various lists of Node children by using
6600 dictionaries to avoid "x in list" searches.
6602 - Cache the computed list of Node children minus those being Ignored
6603 so it's only calculated once.
6605 - Fix use of the --cache-show option when building a Program()
6606 (or using any other arbitrary action) by making sure all Action
6607 instances have strfunction() methods.
6609 - Allow the source of Command() to be a directory.
6611 - Better error handling of things like raw TypeErrors in SConscripts.
6613 - When installing using "setup.py install --prefix=", suppress the
6614 distutils warning message about adding the (incorrect) library
6615 directory to your search path.
6617 - Correct the spelling of the "validater" option to "validator."
6618 Add a DeprecatedWarning when the old spelling is used.
6620 - Allow a Builder's emitter to be a dictionary that maps source file
6621 suffixes to emitter functions, using the suffix of the first file
6622 in the source list to pick the right one.
6624 - Refactor the creation of the Program, *Object and *Library Builders
6625 so that they're moved out of SCons.Defaults and created on demand.
6627 - Don't split SConscript file names on white space.
6629 - Document the SConscript function's "dirs" and "name" keywords.
6631 - Remove the internal (and superfluous) SCons.Util.argmunge() function.
6633 - Add /TP to the default CXXFLAGS for msvc, so it can compile all
6634 of the suffixes we use as C++ files.
6636 - Allow the "prefix" and "suffix" attributes of a Builder to be
6637 callable objects that return generated strings, or dictionaries
6638 that map a source file suffix to the right prefix/suffix.
6640 - Support a MAXLINELINELENGTH construction variable on Win32 systems
6641 to control when a temporary file is used for long command lines.
6643 - Make how we build .rpm packages not depend on the installation
6644 locations from the distutils being used.
6646 - When deducing a target Node, create it directly from the first
6647 source Node, not by trying to create the right string to pass to
6650 - Add support for SWIG.
6652 From Bram Moolenaar:
6654 - Test portability fixes for FreeBSD.
6656 From Gary Oberbrunner:
6658 - Report the target being built in error messages when building
6659 multiple sources from different extensions, or when the target file
6660 extension can't be deduced, or when we don't have an action for a
6663 - Provide helpful error messages when the arguments to env.Install()
6666 - Fix the value returned by the Node.prevsiginfo() method to conform
6667 to a previous change when checking whether a node is current.
6669 - Supply a stack trace if the Taskmaster catches an exception.
6671 - When using a temporary file for a long link line on Win32 systems,
6672 (also) print the command line that is being executed through the
6675 - Initialize the LIB environment variable when using the Intel
6678 - Documentation fixes: better explain the AlwaysBuild() function.
6680 From Laurent Pelecq:
6682 - When the -debug=pdb option is specified, use pdb.Pdb().runcall() to
6683 call pdb directly, don't call Python recursively.
6687 - Add support for a platform-independent CPPDEFINES variable.
6689 From Christoph Wiedemann:
6691 - Have the g++ Tool actually use g++ in preference to c++.
6693 - Have the gcc Tool actually use gcc in preference to cc.
6695 - Add a gnutools.py test of the GNU tool chain.
6697 - Be smarter about linking: use $CC by default and $CXX only if we're
6698 linking with any C++ objects.
6700 - Avoid SCons hanging when a piped command has a lot of output to read.
6702 - Add QT support for preprocessing .ui files into .c files.
6706 RELEASE 0.90 - Wed, 25 Jun 2003 14:24:52 -0500
6710 - Fix the _concat() documentation, and add a test for it.
6712 - Portability fixes for non-GNU versions of lex and yacc.
6716 - Fix handling of library prefixes when the subdirectory matches
6719 From Timothee Bessett:
6721 - Add an M4 Builder.
6725 - Use '.lnk' as the suffix on the temporary file for linking long
6726 command lines (necessary for the Phar Lap linkloc linker).
6728 - Save non-string Options values as their actual type.
6730 - Save Options string values that contain a single quote correctly.
6732 - Save any Options values that are changed from the default
6733 Environment values, not just ones changed on the command line or in
6736 - Make closing the Options file descriptor exception-safe.
6740 - SCons now enforces (with an error) that construction variables
6741 must have the same form as valid Python identifiers.
6743 - Fix man page bugs: remove duplicate AddPostAction() description;
6744 document no_import_lib; mention that CPPFLAGS does not contain
6745 $_CPPINCFLAGS; mention that F77FLAGS does not contain $_F77INCFLAGS;
6746 mention that LINKFLAGS and SHLINKFLAGS contains neither $_LIBFLAGS
6749 - Eliminate a dependency on the distutils.fancy_getopt module by
6750 copying and pasting its wrap_text() function directly.
6752 - Make the Script.Options() subclass match the underlying base class
6755 - When reporting a target is up to date, quote the target like make
6756 (backquote-quote) instead of with double quotes.
6758 - Fix handling of ../* targets when using -U, -D or -u.

6776 - Add CheckFunc and CheckType functionality to SConf.
6778 - Fix use of SConf with Builders that return a list of nodes.
6780 From David Snopek and Christoph Wiedemann
6782 - Fix use of the SConf subsystem with SConscriptChdir().
6786 - Check for the existence of MS Visual Studio on disk before using it,
6787 to avoid getting fooled by leftover junk in the registry.
6789 - Add support for MSVC++ .NET.
6791 - Add support for MS Visual Studio project files (DSP, DSW,
6792 SLN and VCPROJ files).

6805 when compiling them.
6807 - Use 'rm' to remove files under Cygwin.
6809 - Add a PLATFORM variable to construction environments.
6811 - Remove the "platform" argument from tool specifications.

6814 can be found in non-standard locations.
6816 - Using MSVC long command-line linking when running Cygwin.
6818 - Portability fixes for a lot of tests.
6820 - Add a Value Node class for dependencies on in-core Python values.

6842 - Pass Nodes, not strings, to Builder emitter functions.
6844 - Refactor command-line interpolation and signature calculation
6845 so we can use real Node attributes.
6849 - Add Java support (javac, javah, jar and rmic).

6856 - Check out CVS source files using POSIX path names (forward slashes
6857 as separators) even on Win32.
6859 - Add Node.clear() and Node.FS.Entry.clear() methods to wipe out a

6869 - Interpolate the null string if an out-of-range subscript is used
6870 for a construction variable.
6872 - Fix the internal Link function so that it properly links or copies
6873 files in subsidiary BuildDir directories.
6875 - Refactor the internal representation of a single execution instance
6876 of an action to eliminate redundant signature calculations.

6911 - Fix a number of tests that searched for a Fortran compiler using the
6912 external PATH instead of what SCons would use.
6914 - Fix the interaction of SideEffect() and BuildDir() so that (for
6915 example) PDB files get put correctly in a BuildDir().
6919 - Contribute the "Autoscons" code for Autoconf-like checking for
6920 the existence of libraries, header files and the like.
6922 - Have the Tool() function add the tool name to the $TOOLS

6934 - Add an IDL scanner.
6936 - Refactor the Fortran, C and IDL scanners to share common logic.
6938 - Add .srcpath and .srcdir attributes to $TARGET and $SOURCE.
6940 From Christoph Wiedemann:
6942 - Integrate David Snopek's "Autoscons" code as the new SConf
6943 configuration subsystem, including caching of values between
6944 runs (using normal SCons dependency mechanisms), tests, and
6949 RELEASE 0.13 - Mon, 31 Mar 2003 20:22:00 -0600
6953 - Fix a bug when BuildDir(duplicate=0) is used and SConscript
6954 files are called from within other SConscript files.
6956 - Support (older) versions of Perforce which don't set the Windows
6961 RELEASE 0.12 - Thu, 27 Mar 2003 23:52:09 -0600
6965 - Added support for the Perforce source code management system.
6967 - Fix str(Node.FS) so that it returns a path relative to the calling
6968 SConscript file's directory, not the top-level directory.
6970 - Added support for a separate src_dir argument to SConscript()
6971 that allows explicit specification of where the source files
6972 for an SConscript file can be found.
6974 - Support more easily re-usable flavors of command generators by
6975 calling callable variables when strings are expanded.
6979 - Added an INSTALL construction variable that can be set to a function
6980 to control how the Install() and InstallAs() Builders install files.
6981 The default INSTALL function now copies, not links, files.
6983 - Remove deprecated features: the "name" argument to Builder objects,
6984 and the Environment.Update() method.
6986 - Add an Environment.SourceCode() method to support fetching files
6987 from source code systems. Add factory methods that create Builders
6988 to support BitKeeper, CVS, RCS, and SCCS. Add support for fetching
6989 files from RCS or SCCS transparently (like GNU Make).
6991 - Make the internal to_String() function more efficient.
6993 - Make the error message the same as other build errors when there's a
6994 problem unlinking a target file in preparation for it being built.

6997 warn if the user tries to set them in a construction environment.
6999 - Add support for Tar and Zip files.
7001 - Better documentation of the different ways to export variables to a
7002 subsidiary SConscript file. Fix documentation bugs in a tools

7006 - Support fetching arbitrary files from the TARGETS or SOURCES lists
7007 (e.g. ${SOURCES[2]}) when calculating the build signature of a
7010 - Don't silently swallow exceptions thrown by Scanners (or other
7011 exceptions while finding a node's dependent children).
7013 - Push files to CacheDir() before calling the superclass built()
7014 method (which may clear the build signature as part of clearing
7015 cached implicit dependencies, if the file has a source scanner).
7016 (Bug reported by Jeff Petkau.)
7018 - Raise an internal error if we attempt to push a file to CacheDir()
7019 with a build signature of None.
7021 - Add an explicit Exit() function for terminating early.
7023 - Change the documentation to correctly describe that the -f option
7024 doesn't change to the directory in which the specified file lives.
7026 - Support changing directories locally with SConscript directory
7027 path names relative to any SConstruct file specified with -f.
7028 This allows you to build in another directory by simply changing
7029 there and pointing at the SConstruct file in another directory.
7031 - Change the default SConscriptChdir() behavior to change to the
7032 SConscript directory while it's being read.
7034 - Fix an exception thrown when the -U option was used with no

7044 - Fix WhereIs() to return normalized paths.
7048 - Don't copy a built file to a CacheDir() if it's already there.
7050 - Avoid partial copies of built files in a CacheDir() by copying
7051 to a temporary file and renaming.
7055 - Fix incorrect dependency-cycle errors when an Aliased source doesn't
7060 RELEASE 0.11 - Tue, 11 Feb 2003 05:24:33 -0600
7064 - Add support for IRIX and the SGI MIPSPro tool chain.
7066 - Support using the MSVC tool chain when running Cygwin Python.
7070 - Avoid losing signal bits in the exit status from a command,
7071 helping terminate builds on interrupt (CTRL+C).
7075 - Added new AddPreAction() and AddPostAction() functions that support
7076 taking additional actions before or after building specific targets.
7078 - Add support for the PharLap ETS tool chain.
7082 - Allow Python function Actions to specify a list of construction
7083 variables that should be included in the Action's signature.

7086 and suffix, even when using the GNU linker.
7087 (Bug reported by Neal Becker.)
7089 - Use DOS-standard CR-LF line endings in the scons.bat file.
7090 (Bug reported by Gary Ruben.)
7092 - Doc changes: Eliminate description of deprecated "name" keyword
7093 argument from Builder definition (reported by Gary Ruben).
7095 - Support using env.Append() on BUILDERS (and other dictionaries).
7096 (Bug reported by Bj=F6rn Bylander.)
7098 - Setting the BUILDERS construction variable now properly clears
7099 the previous Builder attributes from the construction Environment.
7100 (Bug reported by Bj=F6rn Bylander.)
7102 - Fix adding a prefix to a file when the target isn't specified.
7103 (Bug reported by Esa Ilari Vuokko.)
7105 - Clean up error messages from problems duplicating into read-only
7106 BuildDir directories or into read-only files.
7108 - Add a CommandAction.strfunction() method, and add an "env" argument
7109 to the FunctionAction.strfunction() method, so that all Action
7110 objects have strfunction() methods, and the functions for building
7111 and returning a string both take the same arguments.
7113 - Add support for new CacheDir() functionality to share derived files
7114 between builds, with related options --cache-disable, --cache-force,
7117 - Change the default behavior when no targets are specified to build
7118 everything in the current directory and below (like Make). This
7119 can be disabled by specifying Default(None) in an SConscript.
7121 - Revamp SCons installation to fix a case-sensitive installation
7122 on Win32 systems, and to add SCons-specific --standard-lib,
7123 --standalone-lib, and --version-lib options for easier user
7124 control of where the libraries get installed.
7126 - Fix the ability to directly import and use Platform and Tool modules
7127 that have been implicitly imported into an Environment().
7129 - Add support for allowing an embedding interface to annotate a node
7132 - Extend the SConscript() function to accept build_dir and duplicate
7133 keyword arguments that function like a BuildDir() call.
7137 - Fix the output of -c -n when directories are involved, so it
7142 - Use a different shared object suffix (.os) when using gcc so shared
7143 and static objects can exist side-by-side in the same directory.
7145 - Allow the same object files on Win32 to be linked into either
7146 shared or static libraries.
7148 - Cache implicit cache values when using --implicit-cache.
7152 RELEASE 0.10 - Thu, 16 Jan 2003 04:11:46 -0600
7154 From Derrick 'dman' Hudson:
7156 - Support Repositories on other file systems by symlinking or
7157 copying files when hard linking won't work.
7161 - Remove Python bytecode (*.pyc) files from the scons-local packages.
7163 - Have FunctionActions print a description of what they're doing
7164 (a representation of the Python call).
7166 - Fix the Install() method so that, like other actions, it prints
7167 what would have happened when the -n option is used.
7169 - Don't create duplicate source files in a BuildDir when the -n
7172 - Refactor the Scanner interface to eliminate unnecessary Scanner
7173 calls and make it easier to write efficient scanners.
7175 - Added a "recursive" flag to Scanner creation that specifies the
7176 Scanner should be invoked recursively on dependency files returned
7179 - Significant performance improvement from using a more efficient
7180 check, throughout the code, for whether a Node has a Builder.
7182 - Fix specifying only the source file to MultiStepBuilders such as
7183 the Program Builder. (Bug reported by Dean Bair.)
7185 - Fix an exception when building from a file with the same basename as
7186 the subdirectory in which it lives. (Bug reported by Gerard Patel.)
7188 - Fix automatic deduction of a target file name when there are
7189 multiple source files specified; the target is now deduced from just
7190 the first source file in the list.
7192 - Documentation fixes: better initial explanation of SConscript files;
7193 fix a misformatted "table" in the StaticObject explanation.
7195 From Steven Knight and Steve Leblanc:
7197 - Fix the -c option so it will remove symlinks.
7201 - Add a Clean() method to support removing user-specified targets
7202 when using the -c option.
7204 - Add a development script for running SCons through PyChecker.
7206 - Clean up things found by PyChecker (mostly unnecessary imports).
7208 - Add a script to use HappyDoc to create HTML class documentation.
7212 - Make the Environment.get() method return None by default.
7216 - Add SetJobs() and GetJobs() methods to allow configuration of the
7217 number of default jobs (still overridden by -j).
7219 - Convert the .sconsign file format from ASCII to a pickled Python
7222 - Error message cleanups: Made consistent the format of error
7223 messages (now all start with "scons: ***") and warning messages (now
7224 all start with "scons: warning:"). Caught more cases with the "Do
7225 not know how to build" error message.
7227 - Added support for the MinGW tool chain.
7229 - Added a --debug=includes option.
7233 RELEASE 0.09 - Thu, 5 Dec 2002 04:48:25 -0600
7237 - Add a Prepend() method to Environments, to append values to
7238 the beginning of construction variables.
7242 - Add long command-line support to the "lib" Tool (Microsoft library
7247 - Allow $$ in a string to be passed through as $.
7249 - Support file names with odd characters in them.
7251 - Add support for construction variable substition on scanner
7252 directories (in CPPPATH, F77PATH, LIBPATH, etc.).
7254 From Charles Crain and Steven Knight:
7256 - Add Repository() functionality, including the -Y option.
7260 - Fix auto-deduction of target names so that deduced targets end
7261 up in the same subdirectory as the source.
7263 - Don't remove source files specified on the command line!
7265 - Suport the Intel Fortran Compiler (ifl.exe).
7267 - Supply an error message if there are no command-line or
7268 Default() targets specified.
7270 - Fix the ASPPCOM values for the GNU assembler.
7271 (Bug reported by Brett Polivka.)
7273 - Fix an exception thrown when a Default() directory was specified
7274 when using the -U option.
7276 - Issue a warning when -c can't remove a target.
7278 - Eliminate unnecessary Scanner calls by checking for the
7279 existence of a file before scanning it. (This adds a generic
7280 hook to check an arbitrary condition before scanning.)
7282 - Add explicit messages to tell when we're "Reading SConscript files
7283 ...," "done reading SConscript files," "Building targets," and
7284 "done building targets." Add a -Q option to supress these.
7286 - Add separate $SHOBJPREFIX and $SHOBJSUFFIX construction variables
7287 (by default, the same as $OBJPREFIX and $OBJSUFFIX).
7289 - Add Make-like error messages when asked to build a source file,
7290 and before trying to build a file that doesn't have all its source
7291 files (including when an invalid drive letter is used on WIN32).
7293 - Add an scons-local-{version} package (in both .tar.gz and .zip
7294 flavors) to help people who want to ship SCons as a stand-alone
7295 build tool in their software packages.
7297 - Prevent SCons from unlinking files in certain situations when
7298 the -n option is used.
7300 - Change the name of Tool/lib.py to Tool/mslib.py.
7302 From Steven Knight and Anthony Roach:
7304 - Man page: document the fact that Builder calls return Node objects.
7308 - Refactor option processing to use our own version of Greg Ward's
7309 Optik module, modified to run under Python 1.5.2.
7311 - Add a ParseConfig() command to modify an environment based on
7312 parsing output from a *-config command.
7316 - Fix interpretation of '#/../foo' on Win32 systems.
7320 - Fixed use of command lines with spaces in their arguments,
7321 and use of Nodes with spaces in their string representation.
7323 - Make access and modification times of files in a BuildDir match
7324 the source file, even when hard linking isn't available.
7326 - Make -U be case insensitive on Win32 systems.
7328 - Issue a warning and continue when finding a corrupt .sconsign file.
7330 - Fix using an alias as a dependency of a target so that if one of the
7331 alias' dependencies gets rebuilt, the resulting target will, too.
7333 - Fix differently ordered targets causing unnecessary rebuilds
7334 on case insensitive systems.
7336 - Use os.system() to execute external commands whenever the "env"
7337 utility is available, which is much faster than fork()/exec(),
7338 and fixes the -j option on several platforms.
7340 - Fix use of -j with multiple targets.
7342 - Add an Options() object for friendlier accomodation of command-
7345 - Add support for Microsoft VC++ precompiled header (.pch) files,

7348 - Don't compute the $_CPPINCFLAGS, $_F77INCFLAGS, $_LIBFLAGS and
7349 $_LIBDIRFLAGS variables each time a command is executed, define
7350 them so they're computed only as needed. Add a new _concat
7351 function to the Environment that allows people to define their
7352 own similar variables.
7354 - Fix dependency scans when $LIBS is overridden.
7356 - Add EnsurePythonVersion() and EnsureSConsVersion() functions.
7358 - Fix the overly-verbose stack trace on ListBuilder build errors.
7360 - Add a SetContentSignatureType() function, allowing use of file
7361 timestamps instead of MD5 signatures.
7363 - Make -U and Default('source') fail gracefully.
7365 - Allow the File() and Dir() methods to take a path-name string as
7366 the starting directory, in addition to a Dir object.

7369 and ESCAPE construction variables.
7371 - Allow construction variables to be overridden when a Builder
7376 - Dynamically check for the existence of utilities with which to
7377 initialize Environments by default.
7381 RELEASE 0.08 - Mon, 15 Jul 2002 12:08:51 -0500
7385 - Fixed a bug with relative CPPPATH dirs when using BuildDir().
7386 (Bug reported by Bob Summerwill.)
7388 - Added a warnings framework and a --warn option to enable or
7391 - Make the C scanner warn users if files referenced by #include
7392 directives cannot be found and --warn=dependency is specified.
7394 - The BUILDERS construction variable should now be a dictionary
7395 that maps builder names to actions. Existing uses of lists,
7396 and the Builder name= keyword argument, generate warnings
7397 about use of deprecated features.
7399 - Removed the "shared" keyword argument from the Object and
7402 - Added separated StaticObject, SharedObject, StaticLibrary and
7403 SharedLibrary builders. Made Object and Library synonyms for
7404 StaticObject and StaticLibrary, respectively.
7406 - Add LIBS and LIBPATH dependencies for shared libraries.
7408 - Removed support for the prefix, suffix and src_suffix arguments
7409 to Builder() to be callable functions.

7415 - Add a FindFile() function that searches for a file node with a
7418 - Add $CPPFLAGS to the shared-object command lines for g++ and gcc.
7420 From Charles Crain and Steven Knight:
7422 - Add a "tools=" keyword argument to Environment instantiation,
7423 and a separate Tools() method, for more flexible specification
7424 of tool-specific environment changes.
7428 - Add a "platform=" keyword argument to Environment instantiation,
7429 and a separate Platform() method, for more flexible specification
7430 of platform-specific environment changes.
7432 - Updated README instructions and setup.py code to catch an
7433 installation failure from not having distutils installed.
7435 - Add descriptions to the -H help text for -D, -u and -U so
7436 people can tell them apart.
7438 - Remove the old feature of automatically splitting strings
7439 of file names on white space.
7441 - Add a dependency Scanner for native Fortran "include" statements,
7442 using a new "F77PATH" construction variable.
7444 - Fix C #include scanning to detect file names with characters like
7447 - Add more specific version / build output to the -v option.
7449 - Add support for the GNU as, Microsoft masm, and nasm assemblers.
7451 - Allow the "target" argument to a Builder call to be omitted, in
7452 which case the target(s) are deduced from the source file(s) and the
7453 Builder's specified suffix.
7455 - Add a tar archive builder.
7457 - Add preliminary support for the OS/2 Platform, including the icc
7462 - Fix --implicit-cache if the scanner returns an empty list.
7466 - Add a "multi" keyword argument to Builder creation that specifies
7467 it's okay to call the builder multiple times for a target.
7469 - Set a "multi" on Aliases so multiple calls will append to an Alias.
7471 - Fix emitter functions' use of path names when using BuildDir or
7474 - Fix --implicit-cache causing redundant rebuilds when the header
7477 - Fix --implicit-cache when a file has no implicit dependencies and
7478 its source is generated.
7480 - Make the drive letters on Windows always be the same case, so that
7481 changes in the case of drive letters don't cause a rebuild.
7483 - Fall back to importing the SCons.TimeStamp module if the SCons.MD5
7484 module can't be imported.
7486 - Fix interrupt handling to guarantee that a single interrupt will
7487 halt SCons both when using -j and not.
7489 - Fix .sconsign signature storage so that output files of one build
7490 can be safely used as input files to another build.
7492 - Added a --debug=time option to print SCons execution times.
7494 - Print an error message if a file can't be unlinked before being
7495 built, rather than just silently terminating the build.
7497 - Add a SideEffect() method that can be used to tell the build
7498 engine that a given file is created as a side effect of building
7499 a target. A file can be specified as a side effect of more than
7500 one build comand, in which case the commands will not be executed
7503 - Significant performance gains from not using our own version of
7504 the inefficient stock os.path.splitext() method, caching source
7505 suffix computation, code cleanup in MultiStepBuilder.__call__(),
7506 and replicating some logic in scons_subst().
7508 - Add --implicit-deps-changed and --implicit-deps-unchanged options.
7510 - Add a GetLaunchDir() function.
7512 - Add a SetBuildSignatureType() function.
7516 - Add an Append() method to Environments, to append values to
7517 construction variables.
7519 - Change the name of Update() to Replace(). Keep Update() as a
7520 deprecated synonym, at least for now.
7522 From Terrel Shumway:
7524 - Use a $PYTHON construction variable, initialized to sys.executable,
7525 when using Python to build parts of the SCons packages.
7527 - Use sys.prefix, not sys.exec_prefix, to find pdb.py.
7531 RELEASE 0.07 - Thu, 2 May 2002 13:37:16 -0500
7535 - Changes to build SCons packages on IRIX (and other *NIces).
7537 - Don't create a directory Node when a file already exists there,
7540 - Add 'dirs' and 'names' keyword arguments to SConscript for
7541 easier specification of subsidiary SConscript files.
7545 - Internal cleanup of environment passing to function Actions.
7547 - Builders can now take arbitrary keyword arguments to create
7548 attributes to be passed to: command generator functions,
7549 FunctionAction functions, Builder emitter functions (below),
7550 and prefix/suffix generator functions (below).
7552 - Command generator functions can now return ANYTHING that can be
7553 converted into an Action (a function, a string, a CommandGenerator
7554 instance, even an ActionBase instance).
7556 - Actions now call get_contents() with the actual target and source
7557 nodes used for the build.
7559 - A new DictCmdGenerator class replaces CompositeBuilder to support
7560 more flexible Builder behavior internally.
7562 - Builders can now take an emitter= keyword argument. An emitter
7563 is a function that takes target, source, and env argument, then
7564 return a 2-tuple of (new sources, new targets). The emitter is
7565 called when the Builder is __call__'ed, allowing a user to modify
7566 source and target lists.
7568 - The prefix, suffix and src_suffix Builder arguments now take a
7569 callable as well a string. The callable is passed the Environment
7570 and any extra Builder keyword arguments and is expected to return
7571 the appropriate prefix or suffix.
7573 - CommandActions can now be a string, a list of command + argument
7574 strings, or a list of commands (strings or lists).
7576 - Added shared library support. The Object and Library Builders now
7577 take a "shared=1" keyword argument to specify that a shared object
7578 or shared library should be built. It is an error to try to build
7579 static objects into a shared library or vice versa.
7581 - Win32 support for .def files has been added. Added the Win32-specific
7582 construction variables $WIN32DEFPREFIX, $WIN32DEFSUFFIX,
7583 $WIN32DLLPREFIX and $WIN32IMPLIBPREFIX. When building a .dll,
7584 the new construction variable $WIN32_INSERT_DEF, controls whether
7585 the appropriately-named .def file is inserted into the target
7586 list (if not already present). A .lib file is always added to
7587 a Library build if not present in the list of targets.
7589 - ListBuilder now passes all targets to the action, not just the first.
7591 - Fix so that -c now deletes generated yacc .h files.
7593 - Builder actions and emitter functions can now be initialized, through
7594 construction variables, to things other than strings.
7596 - Make top-relative '#/dir' lookups work like '#dir'.
7598 - Fix for relative CPPPATH directories in subsidiary SConscript files
7601 - Add a for_signature argument to command generators, so that
7602 generators that need to can return distinct values for the
7603 command signature and for executing the command.
7607 - Create a better scons.bat file from a py2bat.py script on the Python
7608 mailing list two years ago (modeled after pl2bat.pl).
7612 - Fix so that -c -n does *not* remove the targets!
7614 - Man page: Add a hierarchical libraries + Program example.
7616 - Support long MSVC linker command lines through a builder action
7617 that writes to a temporary file and uses the magic MSVC "link @file"
7618 argument syntax if the line is longer than 2K characters.
7620 - Fix F77 command-line options on Win32 (use /Fo instead of -o).
7622 - Use the same action to build from .c (lower case) and .C (upper
7623 case) files on case-insensitive systems like Win32.
7625 - Support building a PDF file directly from a TeX or LaTeX file
7626 using pdftex or pdflatex.
7628 - Add a -x option to runtest.py to specify the script being tested.
7629 A -X option indicates it's an executable, not a script to feed
7630 to the Python interpreter.
7632 - Add a Split() function (identical to SCons.Util.argmunge()) for use
7633 in the next release, when Builders will no longer automatically split
7634 strings on white space.
7638 - Add the SConscriptChdir() method.
7642 - Fix --debug=tree when used with directory targets.
7644 - Significant internal restructuring of Scanners and Taskmaster.
7646 - Added new --debug=dtree option.
7648 - Fixes for --profile option.
7650 - Performance improvement in construction variable substitution.
7652 - Implemented caching of content signatures, plus added --max-drift
7653 option to control caching.
7655 - Implemented caching of dependency signatures, enabled by new
7656 --implicit-cache option.
7658 - Added abspath construction variable modifier.
7660 - Added $SOURCE variable as a synonym for $SOURCES[0].
7662 - Write out .sconsign files on error or interrupt so intermediate
7663 build results are saved.
7665 - Change the -U option to -D. Make a new -U that builds just the
7666 targets from the local SConscript file.
7668 - Fixed use of sys.path so Python modules can be imported from
7669 the SConscript directory.
7671 - Fix for using Aliases with the -u, -U and -D options.
7673 - Fix so that Nodes can be passed to SConscript files.
7677 - Changes for official Debian packaging.

7755 - Set PROGSUFFIX to .exe under Cygwin.
7759 - Allow a library to specified as a command-line source file, not just
7760 in the LIBS construction variable.
7762 - Compensate for a bug in os.path.normpath() that returns '' for './'
7765 - More performance optimizations: cache #include lines from files,
7766 eliminate unnecessary calls.
7768 - If a prefix or suffix contains white space, treat the resulting
7769 concatenation as separate arguments.
7771 - Fix irregularities in the way we fetch DevStudio information from
7772 the Windows registry, and in our registry error handling.
7776 - Flush stdout after print so it intermixes correctly with stderr
7779 - Allow Scanners to return a list of strings, and document how to
7780 write your own Scanners.
7782 - Look up implicit (scanned) dependencies relative to the directory
7783 of file being scanned.
7785 - Make writing .sconsign files more robust by first trying to write

7789 to build any of the targets.
7791 - WIN32 portability fixes in tests.

7796 - Document the overlooked LIBPATH construction variable.
7797 (Bug reported by Eicke Godehardt.)

7800 (included files), not just direct dependencies.
7802 - Put the man page in the Debian distribution.
7804 - Run HTML docs through tidy to clean up the HTML (for Konqueror).
7806 - Add preliminary support for Unicode strings.

7834 RELEASE 0.04 - Wed, 30 Jan 2002 11:09:42 -0600
7838 - Significant performance improvements in the Node.FS and
7841 - Fix signatures of binary files on Win32 systems.
7843 - Allow LIBS and LIBPATH to be strings, not just arrays.
7845 - Print a traceback if a Python-function builder throws an exception.
7849 - Fix using a directory as a Default(), and allow Default() to
7850 support white space in file names for strings in arrays.
7852 - Man page updates: corrected some mistakes, documented various
7853 missing Environment methods, alphabetized the construction
7854 variables and other functions, defined begin and end macros for
7855 the example sections, regularized white space separation, fixed
7856 the use of Export() in the Multiple Variants example.
7858 - Function action fixes: None is now a successful return value.
7859 Exceptions are now reported. Document function actions.
7861 - Add 'Action' and 'Scanner' to the global keywords so SConscript
7862 files can use them too.
7864 - Removed the Wrapper class between Nodes and Walkers.
7866 - Add examples using Library, LIBS, and LIBPATH.
7868 - The C Scanner now always returns a sorted list of dependencies
7869 so order changes don't cause unnecessary rebuilds.
7871 - Strip $(-$) bracketed text from command lines. Use this to
7872 surround $_INCDIRS and $_LIBDIRS so we don't rebuild in response
7873 to changes to -I or -L options.
7875 - Add the Ignore() method to ignore dependencies.
7877 - Provide an error message when a nonexistent target is specified
7878 on the command line.
7880 - Remove targets before building them, and add an Environment
7881 Precious() method to override that.
7883 - Eliminate redundant calls to the same builder when the target is a
7884 list of targets: Add a ListBuilder class that wraps Builders to
7885 handle lists atomically. Extend the Task class to support building

7906 - Performance improvements in the Node.FS and Sig.Calculator classes.
7908 - Add the InstallAs() method.
7910 - Execute commands through an external interpreter (sh, cmd.exe, or
7911 command.com) to handle redirection metacharacters.
7913 - Allow the user to supply a command handler.
7917 - Search both /usr/lib and /usr/local/lib for scons directories by
7918 adding them both to sys.path, with whichever is in sys.prefix first.
7920 - Fix interpreting strings of multiple white-space separated file names
7921 as separate file names, allowing prefixes and suffixes to be appended
7922 to each individually.
7924 - Refactor to move CompositeBuilder initialization logic from the
7925 factory wrapper to the __init__() method, and allow a Builder to
7926 have both an action and a src_builder (or array of them).
7928 - Refactor BuilderBase.__call__() to separate Node creation/lookup
7929 from initialization of the Node's builder information.
7931 - Add a CFile Builder object that supports turning lex (.l) and
7932 yacc (.y) files into .c files.
7934 - Document: variable interpretation attributes; how to propogate
7935 the user's environment variables to executed commands; how to
7936 build variants in multiple BuildDirs.
7938 - Collect String, Dict, and List type-checking in common utility
7939 routines so we can accept User{String,Dict,List}s all over.
7941 - Put the Action factory and classes into their own module.
7943 - Use one CPlusPlusAction in the Object Builder's action dictionary,
7944 instead of letting it create multiple identical instances.
7946 - Document the Install() and InstallAs() methods.
7950 - Require that a Builder be given a name argument, supplying a
7951 useful error message when it isn't.
7955 - Add a "duplicate" keyword argument to BuildDir() that can be set
7956 to prevent linking/copying source files into build directories.
7958 - Add a "--debug=tree" option to print an ASCII dependency tree.
7960 - Fetch the location of the Microsoft Visual C++ compiler(s) from
7961 the Registry, instead of hard-coding the location.
7963 - Made Scanner objects take Nodes, not path names.
7965 - Have the C Scanner cache the #include file names instead of
7966 (re-)scanning the file each time it's called.
7968 - Created a separate class for parent "nodes" of file system roots,
7969 eliminating the need for separate is-parent-null checks everywhere.
7971 - Removed defined __hash__() and __cmp() methods from FS.Entry, in
7972 favor of Python's more efficient built-in identity comparisons.
7976 RELEASE 0.02 - Sun, 23 Dec 2001 19:05:09 -0600
7980 - Added the Install(), BuildDir(), and Export() methods.
7982 - Fix the -C option by delaying setting the top of the FS tree.
7984 - Avoid putting the directory path on the libraries in the LIBS
7985 construction variable.
7987 - Added a GetBuildPath() method to return the full path to the
7988 Node for a specified string.
7990 - Fixed variable substitution in CPPPATH and LIBPATH.
7994 - Fixed the version comment in the scons.bat (the UNIX geek used
7997 - Fix to setup.py so it doesn't require a sys.argv[1] argument.
7999 - Provide make-like warning message for "command not found" and
8002 - Added an EXAMPLES section to the man page.
8004 - Make Default() targets properly relative to their SConscript
8005 file's subdirectory.
8009 - Documented CXXFLAGS, CXXCOM, and CPPPATH.
8011 - Fixed SCONS_LIB_DIR to work as documented.
8013 - Made Default() accept Nodes as arguments.
