3 Implement the MAKE_RESTARTS variable, and disable -B if it's >0.
4 Fixes Savannah bug #7566.
6 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
7 * NEWS: Mention MAKE_RESTARTS.
8 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
9 its export flag and obtain its value. When we need to re-exec,
10 increment the value and add it into the environment.
11 (always_make_set): New variable. Change the -B option to set this
13 (main): When checking makefiles, only set always_make_flag if
14 always_make_set is set AND the restarts flag is 0. When building
15 normal targets, set it IFF always_make_set is set.
17 2005-06-17 Paul D. Smith <psmith@gnu.org>
19 * default.c: Change VMS implicit rules to use $$$$ instead of $$
20 in the prerequisites list.
22 2005-06-12 Paul D. Smith <psmith@gnu.org>
24 Fix Savannah bug # 1328.
26 * configure.in: Check for atexit().
27 * misc.c (close_stdout): Test stdout to see if writes to it have
28 failed. If so, be sure to exit with a non-0 error code. Based on
31 * main.c (main): Install close_stdout() with atexit().
33 2005-06-10 Paul D. Smith <psmith@gnu.org>
35 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
37 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
38 headers; make vmsWaitForChildren() static; extern vmsify().
39 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
40 Don't create child_execute_job() here (it's in vmsjobs.c).
41 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
43 2005-06-09 Paul D. Smith <psmith@gnu.org>
45 * variable.c (push_new_variable_scope): File variables point
46 directly to the global_setlist variable. So, inserting a new
47 scope in front of that has no effect on those variables: they
48 don't go through current_variable_set_list. If we're pushing a
49 scope and the current scope is global, push it "the other way" so
50 that the new setlist is in the global_setlist variable, and
51 next points to a new setlist with the global variable set.
52 (pop_variable_scope): Properly undo a push with the new
54 Fixes Savannah bug #11913.
56 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
58 * job.c (reap_children): Don't die of the command failed but
59 the dontcare flag is set. Fixes Savannah bug #13216.
61 * implicit.c (pattern_search): When creating a target from
62 an implicit rule match, lookup pattern target and set precious
63 flag in a newly created target. Fixes Savannah bug #13218.
65 2005-05-13 Paul D. Smith <psmith@gnu.org>
67 Implement "if... else if... endif" syntax.
69 * read.c (eval): Push all checks for conditional words ("ifeq",
70 "else", etc.) down into the conditional_line() function.
71 (conditional_line): Rework to allow "else if..." clause. New
72 return value -2 for lines which are not conditionals. The
73 ignoring flag can now also be 2, which means "already parsed a
74 true branch". If that value is seen no other branch of this
75 conditional can be considered true. In the else parsing if there
76 is extra text after the else, invoke conditional_line()
77 recursively to see if it's another conditional. If not, it's an
78 error. If so, raise the conditional value to this level instead
79 of creating a new conditional nesting level. Special check for
80 "else" and "endif", which aren't allowed on the "else" line.
81 * doc/make.texi (Conditional Syntax): Document the new syntax.
83 2005-05-09 Paul D. Smith <psmith@gnu.org>
85 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
86 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
87 recurses to the w32 directory, even on non-Windows systems. Use
88 the method suggested in the automake manual.
89 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
90 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
92 2005-05-07 Paul D. Smith <psmith@gnu.org>
94 * main.c (die): If we're dying with a fatal error (not that a
95 command has failed), write back any leftover tokens before we go.
97 * job.c (set_child_handler_action_flags): If there are jobs
98 waiting for the load to go down, set an alarm to go off in 1
99 second. This allows us to wake up from a potentially long-lasting
100 read() and start a new job if the load has gone down. Turn it off
102 (job_noop): Dummy signal handler function.
103 (new_job): Invoke it with the new semantics.
105 * docs/make.texi: Document secondary expansion. Various cleanups
108 2005-05-03 Paul D. Smith <psmith@gnu.org>
110 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
111 the targets which are to ultimately be made are called "goals";
112 see the GNU make manual. Also, MAKECMDGOALS, etc.
114 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
115 .DEFAULT_GOAL, and default_target_name to default_goal_name.
116 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
118 2005-05-02 Paul D. Smith <psmith@gnu.org>
120 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
121 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
122 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
123 functions to vmsjobs.c. #include it into jobs.c.
125 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
126 jobserver tokens. I found that this happens when an exported
127 recursive variable contains a $(shell ...) function reference: in
128 this situation we could "forget" to write back a token.
130 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
131 we have. It's not reliable to depend on the number of children in
132 our linked list so keep a separate count.
133 (new_job): Check jobserver_tokens rather than children &&
134 waiting_jobs. Increment jobserver_tokens when we get one.
135 (free_child): If jobserver_tokens is 0, internal error. If it's
136 >1, write a token back to the jobserver pipe (we don't write a
137 token for the "free" job). Decrement jobserver_tokens.
139 * main.c: Add variable master_job_slots.
140 (main): Set it to hold the number of jobs requested if we're the
141 master process, when using the jobserver.
142 (die): Sanity checks: first test jobserver_tokens to make sure
143 this process isn't holding any tokens we didn't write back.
144 Second, if master_job_slots is set count the tokens left in the
145 jobserver pipe and ensure it's the same as master_job_slots (- 1).
147 2005-04-24 Paul D. Smith <psmith@gnu.org>
149 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
150 with -l# can lose jobserver tokens, because waiting jobs are not
151 consulted properly when checking for the "free" token.
153 * job.c (free_child): Count waiting_jobs as having tokens.
154 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
155 handle jobs waiting for the load to drop.
157 2005-04-23 Paul D. Smith <psmith@gnu.org>
159 * main.c (main): Be careful to not core if a variable setting in
160 the environment doesn't contain an '='. This is illegal but can
161 happen in broken setups.
162 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
164 2005-04-12 Paul D. Smith <psmith@gnu.org>
166 The second expansion feature causes significant slowdown. Timing
167 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
168 read the makefile before the feature, to 11+s to do the same
169 operations after the feature. Additionally, memory usage
170 increased drastically. To fix this I added some intelligence that
171 avoids the overhead of the second expansion unless it's required.
173 * dep.h: Add a new boolean field, need_2nd_expansion.
175 * read.c (eval): When creating the struct dep for the target,
176 check if the name contains a "$"; if so set need_2nd_expansion to 1.
177 (record_files): If there's a "%" in a static pattern rule, it gets
178 converted to "$*" so set need_2nd_expansion to 1.
180 * file.c (expand_deps): Rework to be more efficient. Only perform
181 initialize_file_variables(), set_file_variables(), and
182 variable_expand_for_file() if the need_2nd_expansion is set.
184 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
185 (pattern_search): Ditto.
186 * main.c (handle_non_switch_argument): Ditto.
188 * read.c (read_all_makefiles): Ditto.
189 (eval_makefile): Ditto.
191 2005-04-07 Paul D. Smith <psmith@gnu.org>
193 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
194 * variable.c (sync_Path_environment): Ditto.
195 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
197 * main.c (main): Define the .FEATURES variable.
198 * NEWS: Announce .FEATURES.
199 * doc/make.texi (Special Variables): Document .FEATURES.
201 * remake.c (check_dep): If a file is .PHONY, update it even if
202 it's marked intermediate. Fixes Savannah bug #12331.
204 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
206 * file.c (expand_deps): Factor out the second expansion and
207 prerequisite line parsing logic from snap_deps().
209 * file.c (snap_deps): Use expand_deps(). Expand and parse
210 prerequisites of the .SUFFIXES special target first. Fixes
213 2005-03-13 Paul D. Smith <psmith@gnu.org>
215 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
218 2005-03-11 Paul D. Smith <psmith@gnu.org>
220 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
221 available, not undefined (from Earnie Boyd).
223 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
225 * implicit.c (pattern_search): Mark an intermediate target as
226 precious if it happened to be a prerequisite of some (other)
227 target. Fixes Savannah bug #12267.
229 2005-03-09 Paul D. Smith <psmith@gnu.org>
231 * read.c (eval_makefile): Add alloca(0).
232 (eval_buffer): Ditto.
234 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
236 * main.c (main): Use o_file instead of o_default when defining
237 the .DEFAULT_TARGET special variable.
238 * read.c (eval): Use define_variable_global() instead of
239 define_variable() when setting new value for the .DEFAULT_TARGET
240 special variable. Fixes Savannah bug #12266.
242 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
244 * imlicit.c (pattern_search): Mark files for which an implicit
245 rule has been found as targets. Fixes Savannah bug #12202.
247 2005-03-04 Paul D. Smith <psmith@gnu.org>
250 * doc/make.texi (Automatic Variables): Document $|.
252 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
254 * read.c (record_files): Instead of substituting % with
255 actual stem value in dependency list replace it with $*.
256 This fixes stem triple expansion bug.
258 * implicit.c (pattern_search): Copy stem to a separate
259 buffer and make it a properly terminated string. Assign
260 this buffer instead of STEM (which is not terminated) to
261 f->stem. Instead of substituting % with actual stem value
262 in dependency list replace it with $*. This fixes stem
263 triple expansion bug.
265 2005-03-01 Paul D. Smith <psmith@gnu.org>
267 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
268 on Windows, as it takes a handle not a pid. Just exit.
269 Fix from patch #3679, provided by Alessandro Vesely.
271 * configure.in: Update check for sys_siglist[] from autoconf manual.
272 * signame.c (strsignal): Update to use the new autoconf macro.
274 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
276 * read.c (record_files): Add a check for the list of prerequisites
277 of a static pattern rule being empty. Fixes Savannah bug #12180.
279 2005-02-28 Paul D. Smith <psmith@gnu.org>
281 * doc/make.texi (Text Functions): Update docs to allow the end
282 ordinal for $(wordlist ...) to be 0.
283 * function.c (func_wordlist): Fail if the start ordinal for
284 $(wordlist ...) is <1. Matches documentation.
285 Resolves Savannah support request #103195.
287 * remake.c (update_goal_chain): Fix logic for stopping in -q:
288 previously we were stopping when !-q, exactly the opposite. This
289 has been wrong since version 1.34, in 1994!
290 (update_file): If we got an error don't break out to run more
291 double-colon rules: just return immediately.
292 Fixes Savannah bug #7144.
294 2005-02-27 Paul D. Smith <psmith@gnu.org>
296 * misc.c (end_of_token): Make argument const.
297 * make.h: Update prototype.
299 * function.c (abspath, func_realpath, func_abspath): Use
300 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
301 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
302 * read.c (record_files): Ditto.
303 * variable.c (do_variable_definition): Ditto.
305 * function.c (func_error): Create a new function $(info ...) that
306 simply prints the message to stdout with no extras.
307 (function_table_init): Add new function to the table.
308 * NEWS: Add $(info ...) reference.
309 * doc/make.texi (Make Control Functions): Document it.
311 New feature: if the system supports symbolic links, and the user
312 provides the -L/--check-symlink-time flag, then use the latest
313 mtime between the symlink(s) and the target file.
315 * configure.in (MAKE_SYMLINKS): Check for lstat() and
316 readlink(). If both are available, define MAKE_SYMLINKS.
317 * main.c: New variable: check_symlink_flag.
318 (usage): Add a line for -L/--check-symlink-times to the help string.
319 (switches): Add -L/--check-symlink-times command line argument.
320 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
321 print a warning and disable it again.
322 * make.h: Declare check_symlink_flag.
323 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
324 if the file is a symlink then check each link in the chain and
325 choose the NEWEST mtime we find as the mtime for the file. The
326 newest mtime might be the file itself!
327 * NEWS: Add information about this new feature.
328 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
330 Avoid core dumps described in Savannah bug # 12124:
332 * file.c: New variable snapped_deps remember whether we've run
335 * filedef.h: Extern it.
336 * read.c (record_files): Check snapped_deps; if it's set then
337 we're trying to eval a new target/prerequisite relationship from
338 within a command script, which we don't support. Fatal.
340 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
342 Implementation of the .DEFAULT_TARGET special variable.
344 * read.c (eval): If necessary, update default_target_name when
346 * read.c (record_files): Update default_target_file if
347 default_target_name has changed.
348 * main.c (default_target_name): Define.
349 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
350 default_target_name is set use default_target_file as a root
352 * filedef.h (default_target_name): Declare.
353 * dep.h (free_dep_chain):
354 * misc.c (free_dep_chain): Change to operate on struct nameseq
355 and change name to free_ns_chain.
356 * file.c (snap_deps): Update to use free_ns_chain.
358 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
360 Implementation of the second expansion in explicit rules,
361 static pattern rules and implicit rules.
363 * read.c (eval): Refrain from chopping up rule's dependencies.
364 Store them in a struct dep as a single dependency line. Remove
365 the code that implements SySV-style automatic variables.
367 * read.c (record_files): Adjust the code that handles static
368 pattern rules to expand all percents instead of only the first
369 one. Reverse the order in which dependencies are stored so that
370 when the second expansion reverses them again they appear in
371 the makefile order (with some exceptions, see comments in
372 the code). Remove the code that implements SySV-style automatic
375 * file.c (snap_deps): Implement the second expansion and chopping
376 of dependency lines for explicit rules.
378 * implicit.c (struct idep): Define an auxiliary data type to hold
379 implicit rule's dependencies after stem substitution and
382 * implicit.c (free_idep_chain): Implement.
384 * implicit.c (get_next_word): Implement helper function for
385 parsing implicit rule's dependency lines into words taking
386 into account variable expansion requests. Used in the stem
389 * implicit.c (pattern_search): Implement the second expansion
390 for implicit rules. Also fixes bug #12091.
392 * commands.h (set_file_variables): Declare.
393 * commands.c (set_file_variables): Remove static specifier.
395 * dep.h (free_dep_chain): Declare.
396 * misc.c (free_dep_chain): Implement.
398 * variable.h (variable_expand_for_file): Declare.
399 * expand.c (variable_expand_for_file): Remove static specifier.
401 * make.h (strip_whitespace): Declare.
402 * function.c (strip_whitespace): Remove static specifier.
404 2005-02-26 Paul D. Smith <psmith@gnu.org>
406 * main.c (main): Check for ferror() when reading makefiles from stdin.
407 Apparently some shells in Windows don't close pipes properly and
410 2005-02-24 Jonathan Grant <jg@jguk.org>
412 * configure.in: Add MinGW configuration options, and extra w32 code
414 * Makefile.am: Add MinGW configuration options, and extra w32 code
416 * main.c: Determine correct program string (after last \ without .exe).
417 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
419 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
420 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
421 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
424 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
426 * function.c (func_shell): When initializing error_prefix, check
427 that reading file name is not null. This fixes long-standing
428 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
430 2005-02-09 Paul D. Smith <psmith@gnu.org>
432 * maintMakefile: Update the CVS download URL to simplify them.
433 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
434 downloading the .texi files from Savannah now.
436 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
438 * main.c (handle_non_switch_argument): Only add variables to
439 command_variables if they're not already there: duplicate settings
440 waste space and can be confusing to read.
442 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
443 this header is never included by non-WINDOWS32 code, and it
444 requires <config.h> to define which isn't always included first.
446 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
447 testing MINGW32 versions.
449 * main.c (log_working_directory): flush stdout to be sure the WD
450 change is printed before any stderr messages show up.
452 2005-02-01 Paul D. Smith <psmith@gnu.org>
454 * maintMakefile (po_repo): Update the GNU translation site URL.
456 2004-12-01 Paul D. Smith <psmith@gnu.org>
458 * main.c (main): Change char* env_shell to struct variable shell_var.
459 * variable.c (target_environment): Use new shell_var.
461 2004-11-30 Paul D. Smith <psmith@gnu.org>
463 * configure.in: The old way we avoided creating build.sh from
464 build.sh.in before build.sh.in exists doesn't work anymore; we
465 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
466 the help!). This also keeps automake from complaining.
467 * Makefile.am (README): Add a dummy target so automake won't
468 complain that this file doesn't exist when we checkout from CVS.
469 * maintMakefile (.dep_segment): Rewrite this rule since newer
470 versions of automake don't provide DEP_FILES.
472 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
474 Implementation of `realpath' and `abspath' built-in functions.
476 * configure.in: Check for realpath.
477 * function.c (abspath): Return an absolute file name that does
478 not contain any `.' or `..' components, nor repeated `/'.
479 * function.c (func_abspath): For each name call abspath.
480 * function.c (func_realpath): For each name call realpath
481 from libc or delegate to abspath if realpath is not available.
482 * doc/make.texi (Functions for File Names): Document new functions.
483 * doc/make.texi (Quick Reference): Ditto.
485 2004-11-28 Paul D. Smith <psmith@gnu.org>
487 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
488 arguments. Fixes bug #10252.
490 Fix for bug #1276: Handle SHELL according to POSIX requirements.
492 * main.c (main): Set SHELL to v_noexport by default. Remember the
493 original environment setting of SHELL in the env_shell variable.
494 * main.h: Export new env_shell variable.
495 * variable.c (target_environment): If we find a v_noexport
496 variable for SHELL, add a SHELL variable with the env_shell value.
497 * doc/make.texi (Quick Reference): Document the POSIX behavior.
498 * doc/make.texi (Variables/Recursion): Ditto.
500 2004-11-28 Paul D. Smith <psmith@gnu.org>
502 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
503 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
504 Patch by Alessandro Vesely.
506 2004-11-12 Paul D. Smith <psmith@gnu.org>
508 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
509 the command line if it's inside a string.
510 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
512 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
514 * function.c (func_lastword): New function: return last word
515 from the list of words.
516 * doc/make.texi: Document $(lastword ). Fix broken links in
517 Quick Reference section.
519 2004-10-06 Paul D. Smith <psmith@gnu.org>
521 Apply patch from Alessandro Vesely, provided with bug # 9748.
522 Fix use of tmpnam() to work with Borland C.
524 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
525 construction of a temporary filename, and call new function
526 create_batch_filename().
527 (create_batch_filename) [WINDOWS32]: New function to create a
530 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
532 * read.c (record_target_var): Expand simple pattern-specific
534 * variable.c (initialize_file_variables): Do not expand simple
535 pattern-specific variable.
537 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
539 * remake.c (update_file_1): When rebuilding makefiles inherit
540 dontcare flag from a target that triggered update.
542 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
544 * variable.c (initialize_file_variables): Mark pattern-specific
545 variable as a per-target and copy export status.
547 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
549 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
551 * implicit.c (pattern_search): When considering an implicit rule's
552 prerequisite check that it is actually a target rather then
553 just an entry in the file hashtable.
555 2004-09-21 Paul D. Smith <psmith@gnu.org>
557 * read.c (readstring): Fix some logic errors in backslash handling.
558 (eval): Remove some unnecessary processing in buffer handling.
559 (record_target_var): Assert that parse_variable_definition() succeeded.
560 Reported by: Markus Mauhart <qwe123@chello.at>.
562 * misc.c: Removed the sindex() function. All instances of this
563 function were trivially replaceable by the standard strstr()
564 function, and that function will always have better (or certainly
565 no worse) performance than the very simple-minded algorithm
566 sindex() used. This can matter with complex makefiles.
567 * make.h: Remove the prototype for sindex().
568 * function.c (subst_expand): Convert sindex() call to strstr().
569 This means we no longer need to track the TLEN value so remove that.
570 (func_findstring): Convert sindex() to strstr().
571 * commands.c (chop_commands): Convert sindex() calls to strstr().
572 Suggested by: Markus Mauhart <qwe123@chello.at>.
574 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
575 idea behind Savannah Patch #3144 from david.baird@homemail.com.
576 If SHELL is set to CMD.EXE then assume it's batch-mode and
577 non-unixy. I wrote the code differently from the patch, though,
578 to make it safer. This also resolves bug #9174.
580 2004-09-20 Paul D. Smith <psmith@gnu.org>
582 * expand.c (variable_expand_string): Modify to invoke
583 patsubst_expand() instead of subst_expand(); the latter didn't
584 handle suffix patterns correctly.
585 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
586 was used only from variable_expand_string() and is no longer used
588 (func_subst): Ditto, on call to subst_expand().
589 (patsubst_expand): Require the percent pointers to point to the
590 character after the %, not to the % itself.
591 * read.c (record_files): New call criteria for patsubst_expand().
592 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
593 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
595 2004-09-19 Paul D. Smith <psmith@gnu.org>
597 * function.c (subst_expand): Fix a check in by_word: look for a
598 previous blank if we're beyond the beginning of the string, not
599 the beginning of the word.
600 Bugs reported by Markus Mauhart <qwe123@chello.at>.
602 2004-05-16 Paul D. Smith <psmith@gnu.org>
604 * remake.c (update_goal_chain): Change the argument specifying
605 whether we're rebuilding makefiles to be a global variable,
606 REBUILDING_MAKEFILES.
607 (complain): Extract the code that complains about no rules to make
608 a target into a separate function.
609 (update_file_1): If we tried to rebuild a file during the makefile
610 rebuild phase and it was dontcare, then no message was printed.
611 If we then try to build the same file during the normal build,
612 print a message this time.
613 (remake_file): Don't complain about un-remake-able files when
614 we're rebuilding makefiles.
616 2004-05-11 Paul D. Smith <psmith@gnu.org>
618 * job.c (construct_command_argv_internal): OS/2 patches from
619 Andreas Buening <andreas.buening@nexgo.de>.
621 2004-05-10 Paul D. Smith <psmith@gnu.org>
623 * remake.c (update_file): Don't walk the double-colon chain unless
624 this is a double-colon rule. Fix suggested by Boris Kolpackov
625 <boris@kolpackov.net>.
627 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
628 * readme.vms: New section describing OpenVMS support and issues.
629 * default.c (default_variables): Add support for IA64.
630 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
631 without some privilege aborts make with the error
632 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
633 pressing Ctrl+Y and the input device is no terminal. The change
634 catches this error and just continues.
636 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
638 2004-04-25 Paul D. Smith <psmith@gnu.org>
640 * commands.c (set_file_variables): Set $< properly in the face of
641 order-only prerequisites.
642 Patch from Boris Kolpackov <boris@kolpackov.net>
644 2004-04-21 Bob Byrnes <byrnes@curl.com>
646 * main.c (main): Notice failures to remake makefiles.
648 2004-03-28 Paul D. Smith <psmith@gnu.org>
650 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
652 * job.c: No default shell for RISC OS.
653 (load_too_high): Hard-code the return to 1.
654 (construct_command_argv_internal): No sh_chars or sh_cmds.
655 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
657 2004-03-20 Paul D. Smith <psmith@gnu.org>
659 * variable.c (do_variable_definition): Don't append from the
660 global set if a previous non-appending target-specific variable
661 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
664 * expand.c (reference_variable): Don't give up on variables with
665 no value that have the target-specific append flag set: they might
666 have a value after all. Reported by Oliver Schmidt
667 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
668 <nikulin@dx1cmd.inp.nsk.su>.
670 * rule.c (count_implicit_rule_limits): Don't delete patterns which
671 refer to absolute pathnames in directories that don't exist: some
672 portion of the makefile could create those directories before we
673 match the pattern. Fixes bugs #775 and #108.
675 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
677 * main.c (main): Free makefile_mtimes if we have any.
678 * README.W32.template: Update documentation for the current status
679 of the MS-Windows port.
680 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
681 environment variable is sometimes already defined which causes the
683 * main.c (debug_signal_handler): Only define this function if
684 SIGUSR1 is available.
686 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
688 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
689 * README.OS2.template: Documentation updates.
690 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
691 link line for safety.
692 * maintMakefile (build.sh.in): Remove an extraneous ")".
693 * job.c (child_execute_job): Close saved FDs.
694 * job.c (exec_command) [OS/2]: exec_command(): If the command
695 can't be exec'ed and if the shell is not Unix-sh, then try again
696 with argv = { "cmd", "/c", ... }. Normally, this code is never
697 reached for the cmd shell unless the command really doesn't exist.
698 (construct_command_argv_internal) [OS/2]: The code for cmd
699 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
700 The CMD builtin commands are case insensitive so use strcasecmp().
702 2004-03-19 Paul D. Smith <psmith@gnu.org>
704 * read.c (do_define): Re-order line counter increment so the count
705 is accurate (we were losing one line per define). Reported by
706 Dave Yost <Dave@Yost.com>.
708 2004-03-06 Paul D. Smith <psmith@gnu.org>
710 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
712 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
713 * misc.c (message,error,fatal): Ditto.
714 * configh.dos.template: Define HAVE_ANSI_COMPILER.
715 * config.h.W32.template: Ditto.
716 * config.h-vms.template: Ditto.
717 * config.ami.template: Ditto.
719 2004-03-04 Paul D. Smith <psmith@gnu.org>
721 * README.template: Add a note about broken /bin/sh on SunOS
722 4.1.3_U1 & 4.1.4. Fix up Savannah links.
724 * misc.c (message, error, fatal): Don't use "..." if we're using
725 varargs. ansi2knr should handle this but it doesn't work: it
726 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
727 done. On many systems (SunOS for example) va_dcl is a #define.
728 So, force the use of the non-"..." version on pre-ANSI compilers.
730 * maintMakefile (sign-dist): Create some rules to help automate
731 the new GNU ftp upload method.
733 2004-02-24 Paul D. Smith <psmith@gnu.org>
735 * config.h.W32.template: Add HAVE_STDARG_H
736 * config.h-vms.template: Ditto.
737 * config.ami.template: Ditto.
739 2004-02-23 Jonathan Grant <jg-make@jguk.org>
741 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
742 * build_w32.bat: Remove extra "+".
744 2004-02-23 Paul D. Smith <psmith@gnu.org>
746 * make.h: Create an UNUSED macro to mark unused parameters.
747 * (many): Clean up warnings by applying UNUSED, fixing
748 signed/unsigned incompatibilities, etc.
750 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
752 * filedef.h: Name the command_state enumeration.
753 * file.c (set_command_state): Use the enumeration in the function
756 * configure.in: Explicitly set SET_MAKE to empty, to disable
757 MAKE=make even when no make already exists. Fix bug #3823.
759 2004-02-22 Paul D. Smith <psmith@gnu.org>
761 * maintMakefile: Perl script to clean up all non-CVS files. Use
762 it on all the subdirectories for the cvs-clean target.
764 * main.c (decode_switches): Require non-empty strings for all our
765 string command-line options. Fixes Debian bug # 164165.
767 * configure.in: Check for stdarg.h and varargs.h.
768 * make.h (USE_VARIADIC): Set this if we can use variadic functions
769 for printing messages.
770 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
775 A number of patches for OS/2 support from Andreas Buening
776 <andreas.buening@nexgo.de>:
778 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
779 disable the SIGCHLD handler.
780 (reap_children) [OS/2]: Remove special handling of job_rfd.
781 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
782 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
783 * main.c (main) [OS/2]: Special handling for paths in OS/2.
784 * configure.in [OS/2]: Force SA_RESTART for OS/2.
785 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
788 2004-02-21 Paul D. Smith <psmith@gnu.org>
790 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
791 <mail@kristov.de> reports that if process_begin() fails we don't
792 handle the error condition correctly in all cases.
793 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
794 to have a newline on the message.
796 * job.c (construct_command_argv_internal): Add "test" to UNIX
797 sh_cmds[]. Fixes Savannah bug # 7606.
799 2004-02-04 Paul D. Smith <psmith@gnu.org>
801 * job.c (vms_handle_apos) [VMS]: Fix various string handling
802 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
803 Hartmut Becker <Hartmut.Becker@hp.com>.
805 2004-01-21 Paul D. Smith <psmith@gnu.org>
807 * job.c (load_too_high): Implement an algorithm to control the
808 "thundering herd" problem when using -l to control job creation
809 via the load average. The system only recomputes the load once a
810 second but we can start many jobs in a second. To solve this we
811 keep track of the number of jobs started in the last second and
812 apply a weight to try to guess what a correct load would be.
813 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
814 Also fixes bug #4693.
815 (reap_children): Decrease the job count for this second.
816 (start_job_command): Increase the job count for this second.
818 * read.c (conditional_line): Expand the text after ifn?def before
819 checking to see if it's a single word. Fixes bug #7257.
821 2004-01-09 Paul D. Smith <psmith@gnu.org>
823 * file.c (print_file): Recurse to print all targets in
824 double-colon rules. Fixes bug #4518, reported (with patch) by
825 Andrew Chatham <chatham@google.com>.
827 2004-01-07 Paul D. Smith <psmith@gnu.org>
829 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
830 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
831 AC_FUNC_SETVBUF_REVERSED.
833 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
834 (MAKE Variable): Fix Savannah bug #4898.
836 * job.c (construct_command_argv_internal): Add "!" to the list of
837 shell escape chars. POSIX sh allows it to appear before a
838 command, to negate the exit code. Fixes bug #6404.
840 * implicit.c (pattern_search): When matching an implicit rule,
841 remember which dependencies have the ignore_mtime flag set.
842 Original fix provided in Savannah patch #2349, by Benoit
843 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
845 2003-11-22 Paul D. Smith <psmith@gnu.org>
847 * README.W32.template (Outputs): Clarification on -j with
848 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
851 2003-11-02 Paul D. Smith <psmith@gnu.org>
853 * function.c (func_if): Strip all the trailing whitespace from the
854 condition, then don't expand it. Fixed bug # 5798.
856 * expand.c (recursively_expand_for_file): If we're expanding a
857 variable with no file context, then use the variable's context.
860 2003-10-21 Paul D. Smith <psmith@gnu.org>
862 * main.c (log_working_directory): Add newlines to printf()s.
864 * README.cvs: Add a note to ignore warnings during autoreconf.
866 * maintMakefile (po_repo): Set a new URL for PO file updates.
867 (get-config/config.guess get-config/config.sub): Get these files
868 from the Savannah config project instead of ftp.gnu.org.
870 2003-10-05 Paul Eggert <eggert@twinsun.com>
872 * main.c (main): Avoid potential subscript error if environ has
875 2003-08-22 Paul D. Smith <psmith@gnu.org>
877 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
878 systems which don't yet implement the C89 standard :-/.
880 2003-07-18 Paul D. Smith <psmith@gnu.org>
882 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
883 [WINDOWS32]: Initialize hash.
885 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
887 * dir.c (read_dirstream): Provide a workaround for broken versions of
888 the MinGW dirent structure.
890 2003-05-30 Earnie Boyd <earnie@users.sf.net>
892 * w32/include/dirent.h: Add __MINGW32__ filter.
894 2003-05-30 Earnie Boyd <earnie@users.sf.net>
896 * make.h: Add global declaration of *make_host.
897 * main.c (print_usage): Remove local declaration of *make_host.
898 (print_version): Display "This program built for ..." after Copyright
901 2003-05-30 Earnie Boyd <earnie@users.sf.net>
903 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
904 execution of "makeinfo --html make.texi".
906 2003-04-30 Paul D. Smith <psmith@gnu.org>
908 * build.template: Make some changes to maybe allow this script to
909 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
911 * README.OS2.template: New file for OS/2 support. Original
912 contributed by Andreas Buening.
913 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
916 2003-04-19 Paul D. Smith <psmith@gnu.org>
918 Fix bug #1405: allow a target to match multiple pattern-specific
921 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
922 variable.c, where they've always belonged.
923 * rule.h: Move the prototypes and struct pattern_var as well.
924 * variable.c (initialize_file_variables): Invoke
925 lookup_pattern_var() in a loop, until no more matches are found.
926 If a match is found, create a new variable set for the target's
927 pattern variables. Then merge the contents of each matching
928 pattern variable set into the target's pattern variable set.
929 (lookup_pattern_var): Change this function to be usable
930 in a loop. It takes a starting position: if NULL, start at the
931 beginning; if non-NULL, start with the pattern variable after that
932 position, and return the next matching pattern.
933 (create_pattern_var): Create a unique instance of
934 pattern-specific variables for every definition in the makefile.
935 Don't combine the same pattern together. This allows us to
936 process the variable handling properly even when the same pattern
937 is used multiple times.
938 (parse_variable_definition): New function: break out the parsing
939 of a variable definition line from try_variable_definition.
940 (try_variable_definition): Call parse_variable_definition to
942 (print_variable_data_base): Print out pattern-specific variables.
943 * variable.h (struct variable): Remember when a variable is
944 conditional. Also remember its flavor.
945 (struct pattern_var): Instead of keeping a variable set, we just
946 keep a single variable for each pattern.
947 * read.c (record_target_var): Each pattern variable contains only a
948 single variable, not a set, so create it properly.
949 * doc/make.texi (Pattern-specific): Document the new behavior.
951 2003-04-17 Paul D. Smith <psmith@gnu.org>
953 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
954 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
955 file/directory naming rules for VMS so I can't tell whether this
958 2003-04-09 Paul D. Smith <psmith@gnu.org>
960 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
961 DOS-style pathnames: backslash separators and drive specifiers.
963 2003-03-28 Paul D. Smith <psmith@gnu.org>
965 * file.c (snap_deps): If .SECONDARY with no targets is given, set
966 the intermediate flag on all targets. Fixes bug #2515.
968 2003-03-24 Paul D. Smith <psmith@gnu.org>
970 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
971 Upgrade to autoconf 2.57 and automake 1.7.3.
973 * job.c: More OS/2 changes from Andreas Buening.
975 * file.c (print_file): Fix variable initialization.
978 * remake.c (notice_finished_file):
980 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
981 some calls (like readdir()) return NULL in valid situations
982 without resetting errno. Fixes bug #2846.
984 2003-02-25 Paul D. Smith <psmith@gnu.org>
986 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
988 * job.c (_is_unixy_shell) [OS/2]: New function.
989 Set default shell to /bin/sh.
990 (reap_children): Close the job_rfd pipe here since we don't use a
992 (set_child_handler_action_flags): define this to empty on OS/2.
993 (start_job_command): Close the jobserver pipe and use
994 child_execute_job() instead of fork/exec.
995 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
996 rather than exec'ing, then reconfigure stdin/stdout.
997 (exec_command): Rewrite to use spawn instead of exec. Return the
1000 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
1001 in DOS. Handle the TEMP environment variable as in DOS. Don't
1002 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
1003 use -j in DOS mode. Use child_execute_job() instead of
1006 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
1009 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
1010 prototypes that return values.
1012 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
1014 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
1015 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
1017 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
1020 2003-02-24 Paul D. Smith <psmith@gnu.org>
1022 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
1023 * job.c (child_execute_job) [VMS]: New code for handling spawn().
1024 (child_execute_job) [VMS]: Handle error status properly.
1025 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
1027 * function.c (func_shell): Use EINTRLOOP() while reading from the
1028 subshell pipe (Fixes bug #2502).
1029 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
1031 * main.c (main): Ditto.
1033 2003-01-30 Paul D. Smith <psmith@gnu.org>
1035 * read.c (eval): eval() was not fully reentrant, because the
1036 collapsed buffer was static. Change it to be an automatic
1037 variable so that eval() can be invoked recursively.
1039 (eval): Apply patch # 1022: fix memory reference error on long
1040 target-specific variable lines.
1041 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
1043 * function.c (check_numeric): Combine the is_numeric() function
1044 into this function, since it's only called from one place.
1045 Constify this function. Have it print the incorrect string in the
1046 error message. Fixes bug #2407.
1047 (strip_whitespace): Constify.
1048 (func_if): Constify.
1049 * expand.c (expand_argument): Constify.
1051 2003-01-29 Paul D. Smith <psmith@gnu.org>
1053 Fix bug # 2169, also reported by other people on various systems.
1055 * make.h: Some systems, such as Solaris and PTX, do not fully
1056 implement POSIX-compliant SA_RESTART functionality; important
1057 system calls like stat() and readdir() can still fail with EINTR
1058 even if SA_RESTART has been set on the signal handler. So,
1059 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
1060 EINTR for system calls which return -1 or 0 (NULL), respectively,
1062 Also, remove the old atomic_stat()/atomic_readdir() and
1063 HAVE_BROKEN_RESTART handling.
1065 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
1067 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
1068 * remake.c (touch_file): Ditto.
1070 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
1071 * read.c (construct_include_path): Ditto.
1072 * remake.c (name_mtime): Ditto.
1073 * vpath.c (selective_vpath_search): Ditto.
1074 * dir.c (find_directory): Ditto.
1075 (local_stat): Ditto.
1076 (find_directory): Use ENULLLOOP() to wrap opendir().
1077 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
1079 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
1080 atomic_readdir() handling.
1082 2003-01-22 Paul D. Smith <psmith@gnu.org>
1084 * function.c (func_call): Fix Bug #1744. If we're inside a
1085 recursive invocation of $(call ...), mask any of the outer
1086 invocation's arguments that aren't used by this one, so that this
1087 invocation doesn't "inherit" them accidentally.
1089 2002-12-05 Paul D. Smith <psmith@gnu.org>
1091 * function.c (subst_expand): Valery Khamenia reported a
1092 pathological performance hit when doing substitutions on very
1093 large values with lots of words: turns out we were invoking
1094 strlen() a ridiculous number of times. Instead of having each
1095 call to sindex() call strlen() again, keep track of how much of
1096 the text we've seen and pass the length to sindex().
1098 2002-11-19 Paul D. Smith <psmith@gnu.org>
1100 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
1103 2002-11-16 Paul D. Smith <psmith@gnu.org>
1105 * NMakefile.template (OBJS): Add hash.c object file.
1106 * SMakefile.template (srcs): Ditto.
1107 * Makefile.ami (objs): Ditto.
1108 * build_w32.bat: Ditto.
1110 * Makefile.DOS.template: Remove extra dependencies.
1112 2002-10-25 Paul D. Smith <psmith@gnu.org>
1114 * expand.c (install_variable_buffer): New function. Install a new
1115 variable_buffer context and return the previous one.
1116 (restore_variable_buffer): New function. Free the current
1117 variable_buffer context and put a previously saved one back.
1118 * variable.h: Prototypes for {install,restore}_variable_buffer.
1119 * function.c (func_eval): Push a new variable_buffer context
1120 before we eval, then restore the old one when we're done.
1123 * read.c (install_conditionals): New function. Install a new
1124 conditional context and return the previous one.
1125 (restore_conditionals): New function. Free the current
1126 conditional context and put a previously saved one back.
1127 (eval): Use the {install,restore}_conditionals for "include"
1129 (eval_buffer): Use {install,restore}_conditionals to preserve the
1130 present conditional state before we evaluate the buffer.
1133 * doc/make.texi (Quick Reference): Add references to $(eval ...)
1135 (Recursion): Add a variable index entry for CURDIR.
1137 * README.cvs: Update to appropriate versions.
1138 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
1139 don't need to copy loadavg.c: automake is smart enough to create
1140 it for me. Still have a bug in automake related to ansi2knr tho.
1142 2002-10-14 Paul D. Smith <psmith@gnu.org>
1144 * remake.c (notice_finished_file): Only touch targets if they have
1145 at least one command (as per POSIX). Resolve Bug #1418.
1147 * *.c: Convert to using ANSI C-style function definitions.
1148 * Makefile.am: Enable the ansi2knr feature of automake.
1149 * configure.in: ditto.
1151 2002-10-13 Paul D. Smith <psmith@gnu.org>
1153 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
1154 for automatic variable values like $^, etc. In the case of very
1155 large lists of prerequisites this causes problems. Instead reuse
1156 a static buffer (resizeable) for each variable.
1158 * read.c (eval): Fix Bug #1391: allow "export" keyword in
1159 target-specific variable definitions. Check for it and set an
1161 (record_target_var): Set the export field to v_export if the
1162 "exported" flag is set.
1163 * doc/make.texi (Target-specific): Document the ability to use
1166 * doc/make.texi: Change the name of the section on automatic
1167 variables from "Automatic" to "Automatic Variables". Added text
1168 clarifying the scope of automatic variables.
1170 2002-10-04 Paul D. Smith <psmith@gnu.org>
1172 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
1174 (record_files): Ditto.
1176 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
1177 the search for the '=' to only within the enclosing parens.
1179 2002-10-03 Paul D. Smith <psmith@gnu.org>
1181 Version 3.80 released.
1183 * dir.c: Change hash functions to use K&R function definition style.
1184 * function.c: Ditto.
1186 * variable.c: Ditto.
1188 Update to automake 1.7.
1190 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
1191 (pdf): Remove this target as automake now provides one.
1193 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
1195 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
1197 * makefile.com: Updates for GNU make 3.80.
1198 * makefile.vms: Ditto.
1200 2002-09-23 Paul D. Smith <psmith@gnu.org>
1202 * read.c (enum make_word_type): Remove w_comment.
1203 (get_next_mword): Don't treat comment characters as special; where
1204 this function is used we will never see a comment (it's stripped
1205 before we get here) and treating comments specially means that
1206 targets like "foo\#bar" aren't handled properly.
1208 2002-09-18 Paul D. Smith <psmith@gnu.org>
1210 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
1212 * read.c (eval): Expansion of arguments to export/unexport was
1213 ignoring all arguments after the first one. Change the algorithm
1214 to expand the whole line once, then parse the results.
1216 2002-09-17 Paul D. Smith <psmith@gnu.org>
1218 Fix Bug #940 (plus another bug I found while looking at this):
1220 * read.c (record_target_var): enter_file() will add a new entry if
1221 it's a double-colon target: we don't want to do that in this
1222 situation. Invoke lookup_file() and only enter_file() if it does
1223 not already exist. If the file we get back is a double-colon then
1224 add this variable to the "root" double-colon target.
1226 * variable.c (initialize_file_variables): If this file is a
1227 double-colon target but is not the "root" target, then initialize
1228 the root and make the root's variable list the parent of our
1231 2002-09-13 Paul D. Smith <psmith@gnu.org>
1233 * doc/make.texi (MAKE Variable): Add some indexing for "+".
1235 * hash.c (round_up_2): Get rid of a warning.
1237 2002-09-12 Paul D. Smith <psmith@gnu.org>
1239 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
1240 so it doesn't complain about getloadavg.c.
1242 * commands.c (set_file_variables): Make sure we always alloca() at
1243 least 1 character for the value of $? (for '\0').
1245 2002-09-11 Paul D. Smith <psmith@gnu.org>
1247 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
1248 macro to use RESULT instead of the incorrect _RESULT_.
1250 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
1251 and atomic_readdir(). We need to #include dirent.h to get this to
1253 * misc.c (atomic_readdir): Fix typos.
1255 2002-09-10 Paul D. Smith <psmith@gnu.org>
1257 * read.c (eval): Expand variable lists given to export and
1258 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
1259 (conditional_line): Ditto for "ifdef". Fixes bug #103.
1261 * doc/make.texi (Variables/Recursion): Document this.
1262 (Conditional Syntax): And here.
1264 2002-09-09 Paul D. Smith <psmith@gnu.org>
1266 * configure.in: Check for memmove().
1268 2002-09-07 Paul D. Smith <psmith@gnu.org>
1270 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
1271 Michael Sterrett <msterret@coat.com> reports that while it has
1272 SA_RESTART, it does not work properly.
1274 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
1275 that invokes stat() and loops to do it again if it returns EINTR.
1276 (atomic_readdir): Ditto, with readdir().
1278 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
1279 and readdir() to atomic_stat() and atomic_readdir().
1281 2002-09-04 Paul D. Smith <psmith@gnu.org>
1283 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
1284 reports that GNU make sometimes doesn't recognize that targets can
1285 be made, when directories can be created as prerequisites. He
1286 reports that changing the order of predicates in the DEP->changed
1287 flag test so that lookup_file() is always performed, solves this
1290 2002-08-08 Paul D. Smith <psmith@gnu.org>
1292 * configure.in: Require a newer version of gettext.
1294 * misc.c (perror_with_name): Translate the format string (for
1295 right-to-left language support).
1296 (pfatal_with_name): Ditto.
1298 * main.c: Create a static array of strings to store the usage
1299 text. This is done to facilitate translations.
1300 (struct command_switch): Remove argdesc and description fields.
1301 (switches): Remove values for obsolete fields.
1302 (print_usage): Print each element of the usage array.
1304 * hash.c: Change function definitions to be K&R style.
1306 2002-08-02 Paul D. Smith <psmith@gnu.org>
1308 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
1309 this one because it's too hard to get right. We'll look at it for
1311 * main.c (main): Don't create the .TARGETS variable.
1312 * variable.c (handle_special_var): Don't handle .TARGETS.
1314 2002-08-01 Paul D. Smith <psmith@gnu.org>
1316 * main.c (switches): Add a new option, -B (--always-make). If
1317 specified, make will rebuild all targets that it encounters even
1318 if they don't appear to be out of date.
1319 (always_make_flag): New flag.
1320 * make.h: Extern always_make_flag.
1321 * remake.c (update_file_1): Check always_make_flag; if it's set we
1322 will always rebuild any target we can, even if none of its
1323 prerequisites are newer.
1326 * doc/make.texi (Shell Function): Make it clear that make
1327 variables marked as "export" are not passed to instances of the
1330 Add new introspection variable .VARIABLES and .TARGETS.
1332 * variable.c (handle_special_var): New function. If the variable
1333 reference passed in is "special" (.VARIABLES or .TARGETS),
1334 calculate the new value if necessary. .VARIABLES is handled here:
1335 walk through the hash of defined variables and construct a value
1336 which is a list of the names. .TARGETS is handled by
1337 build_target_list().
1338 (lookup_variable): Invoke handle_special_var().
1339 * file.c (build_target_list): Walk through the hask of known files
1340 and construct a list of the names of all the ones marked as
1342 * main.c (main): Initialize them to empty (and as simple variables).
1343 * doc/make.texi (Special Variables): Document them.
1344 * NEWS: Mention them.
1346 * variable.h (struct variable): Add a new flag "exportable" which
1347 is true if the variable name is valid for export.
1348 * variable.c (define_variable_in_set): Set "exportable" when a new
1349 variable is defined.
1350 (target_environment): Use the "exportable" flag instead of
1351 re-checking the name here... an efficiency improvement.
1353 2002-07-31 Paul D. Smith <psmith@gnu.org>
1355 * config.h-vms.template: Updates to build on VMS. Thanks to
1356 Brian_Benning@aksteel.com for helping verify the build.
1357 * makefile.com: Build the new hash.c file.
1358 * hash.h: Use strcpmi(), not stricmp(), in the
1359 HAVE_CASE_INSENSITIVE_FS case.
1361 2002-07-30 Paul D. Smith <psmith@gnu.org>
1363 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
1364 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
1365 Reported by <Brian_Benning@aksteel.com>.
1367 2002-07-10 Paul D. Smith <psmith@gnu.org>
1369 * variable.c (pop_variable_scope): Remove variable made unused by
1370 new hash infrastructure.
1371 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
1372 comparisons as well as name comparisons.
1373 * variable.h: Add a prototype for new hash_init_function_table().
1374 * file.c (lookup_file): Remove variables made unused by new hash
1376 * dir.c (directory_contents_hash_2): Missing return of hash value.
1377 (dir_contents_file_exists_p): Remove variables made unused by new
1378 hash infrastructure.
1381 Installed Greg McGary's integration of the hash functions from the
1382 GNU id-utils package:
1384 2002-07-10 Greg McGary <greg@mcgary.org>
1386 * scripts/functions/filter-out: Add literals to to the
1387 pattern space in order to add complexity, and trigger
1388 use of an internal hash table. Fix documentation strings.
1389 * scripts/targets/INTERMEDIATE: Reverse order of files
1390 passed to expected `rm' command.
1392 2002-07-10 Greg McGary <greg@mcgary.org>

1484 2002-07-10 Paul D. Smith <psmith@gnu.org>
1486 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
1487 prerequisite list. A real SysV make will expand the entire
1488 prerequisites list _twice_: we don't do that as it's a big
1489 backward-compatibility problem. We only replace those specific
1492 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
1493 references left in the list of prerequisites. Check for .POSIX as
1494 we record targets, so we can disable non-POSIX behavior while
1495 reading makefiles as well as running them.
1496 (eval): Check the prerequisite list to see if we have anything
1497 that looks like a SysV prerequisite variable reference.
1499 2002-07-09 Paul D. Smith <psmith@gnu.org>
1501 * doc/make.texi (Prerequisite Types): Add a new section describing
1502 order-only prerequisites.
1504 * read.c (uniquize_deps): If we have the same file as both a
1505 normal and order-only prereq, get rid of the order-only prereq,
1506 since the normal one supersedes it.
1508 2002-07-08 Paul D. Smith <psmith@gnu.org>
1510 * AUTHORS: Added Greg McGary to the AUTHORS file.
1511 * NEWS: Blurbed order-only prerequisites.
1512 * file.c (print_file): Show order-only deps properly when printing
1515 * maintMakefile: Add "update" targets for wget'ing the latest
1516 versions of various external files. Taken from Makefile.maint in
1519 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
1520 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
1522 2002-07-07 Paul D. Smith <psmith@gnu.org>
1524 * po/*.po: Remove. We'll use wget to retrieve them at release
1527 * variable.c (do_variable_definition) [W32]: On W32 using cmd
1528 rather than a shell you get an exception. Make sure we look up
1529 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
1531 * remake.c (notice_finished_file): Fix handling of -t flag.
1532 Patch provided by Henning Makholm <henning@makholm.net>.
1534 * implicit.c (pattern_search): Some systems apparently run short
1535 of stack space, and using alloca() in this function caused an
1536 overrun. I modified it to use xmalloc() on the two variables
1537 which seemed like they might get large. Fixes Bug #476.
1539 * main.c (print_version): Update copyright notice to conform with
1541 (print_usage): Update help output.
1543 * function.c (func_eval): Create a new make function, $(eval
1544 ...). Expand the arguments, put them into a buffer, then invoke
1545 eval_buffer() on the resulting string.
1546 (func_quote): Create a new function, $(quote VARNAME). Inserts
1547 the value of the variable VARNAME without expanding it any
1550 * read.c (struct ebuffer): Change the linebuffer structure to an
1551 "eval buffer", which can be either a file or a buffer.
1552 (eval_makefile): Move the code in the old read_makefile() which
1553 located a makefile into here: create a struct ebuffer with that
1554 information. Have it invoke the new function eval() with that
1556 (eval_buffer): Create a new function that creates a struct ebuffer
1557 that holds a string buffer instead of a file. Have it invoke
1558 eval() with that ebuffer.
1559 (eval): New function that contains the guts of the old
1560 read_makefile() function: this function parses makefiles. Obtains
1561 data to parse from the provided ebuffer. Some modifications to
1562 make the flow of the function cleaner and clearer. Still could
1563 use some work here...
1564 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
1565 contents of the define/endef variable from the ebuffer.
1566 (readstring): Read the next line from a string-style ebuffer.
1567 (readline): Read the next line from an ebuffer. If it's a string
1568 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
1571 * dep.h (eval_buffer): Prototype eval_buffer();
1573 * variable.c (do_variable_definition): Make sure that all
1574 non-target-specific variables are registered in the global set.
1575 If we're invoked from an $(eval ...) we might be inside a $(call
1576 ...) or other function which has pushed a variable scope; we still
1577 want to define our variables from evaluated makefile code in the
1580 2002-07-03 Greg McGary <greg@mcgary.org>
1582 * dep.h (struct dep) [ignore_mtime]: New member.
1583 [changed]: convert to a bitfield.
1584 * implicit.c (pattern_search): Zero ignore_mtime.
1585 * main.c (main, handle_non_switch_argument): Likewise.
1586 * rule.c (convert_suffix_rule): Likewise.
1587 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
1588 (read_makefile): Parse '|' in prerequisite list.
1589 (uniquize_deps): Consider ignore_mtime when comparing deps.
1590 * remake.c (update_file_1, check_dep): Don't force remake for
1591 dependencies that have d->ignore_mtime.
1592 * commands.c (FILE_LIST_SEPARATOR): New constant.
1593 (set_file_variables): Don't include a
1594 prerequisite in $+, $^ or $? if d->ignore_mtime.
1597 2002-06-18 Paul D. Smith <psmith@gnu.org>
1599 * make.texinfo: Updates for next revision. New date/rev/etc.
1600 Recreate all Info menus. Change license on the manual to the GNU
1601 Free Documentation License. A number of typos.
1602 (Variables Simplify): Don't use "-" before it's defined.
1603 (Automatic Prerequisites): Rewrite the target example to work
1604 properly if the compile fails. Remove incorrect comments about
1605 how "set -e" behaves.
1606 (Text Functions): Move the "word", "wordlist", "words", and
1607 "firstword" functions here, from "File Name Functions".
1608 * make-stds.texi: Update from latest GNU version.
1609 * fdl.texi: (created) Import the latest GNU version.
1611 2002-06-06 Paul D. Smith <psmith@gnu.org>
1613 * variable.c (do_variable_definition): New function: extract the
1614 part of try_variable_definition() that actually sets the value
1615 into a separate function.
1616 (try_variable_definition): Call do_variable_definition() after
1617 parsing the variable definition string.
1618 (define_variable_in_set): Make the name argument const.
1620 * variable.h (enum variable_flavor): Make public.
1621 (do_variable_definition): Create prototype.
1623 * read.c (read_all_makefiles): Create a new built-in variable,
1625 (read_makefile): Add each makefile read in to this variable value.
1627 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
1629 * Makefile.DOS.template: Tweak according to changes in the
1630 distribution. Add back the dependencies of *.o files.
1632 * configh.dos.template: Synchronize with config.h.in.
1634 2002-05-09 Paul D. Smith <psmith@gnu.org>
1636 * file.c (file_timestamp_now): Use K&R function declaration.
1638 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
1639 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
1640 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
1641 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
1642 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
1643 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
1644 nlist.n_name is a pointer rather than an array.
1646 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
1647 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
1648 * configure.in: Use it instead of the old version.
1650 * main.c (main): Prefer setvbuf() to setlinebuf().
1652 2002-05-08 Paul D. Smith <psmith@gnu.org>
1654 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
1655 (loadavg_LDADD): Ditto.
1657 2002-04-29 Paul D. Smith <psmith@gnu.org>
1659 * expand.c (recursively_expand_for_file): Rename
1660 recursively_expand() to recursively_expand_for_file() and provide
1661 an extra argument, struct file. If the argument is provided, set
1662 the variable scope to that of the file before expanding.
1663 * variable.h (recursively_expand): Make this a macro that invokes
1664 recursively_expand_for_file() with a NULL file pointer.
1665 * variable.c (target_environment): Call the renamed function and
1666 provide the current file context.
1667 Fixes Debian bug #144306.
1669 2002-04-28 Paul D. Smith <psmith@gnu.org>
1671 Allow $(call ...) user-defined variables to be self-referencing
1672 without throwing an error. Allows implementation of transitive
1673 closures, among other possibly useful things.
1674 Requested by: Philip Guenther <guenther@sendmail.com>
1676 * variable.h (struct variable): Add a new field: exp_count, and
1677 new macros to hold its size and maximum value.
1678 (warn_undefined): Make this a macro.
1679 * variable.c (define_variable_in_set): Initialize it.
1680 * expand.c (recursively_expand): If we detect recursive expansion
1681 of a variable, check the exp_count field. If it's greater than 0
1682 allow the recursion and decrement the count.
1683 (warn_undefined): Remove this (now a macro in variable.h).
1684 * function.c (func_call): Before we expand the user-defined
1685 function, modify its exp_count field to contain the maximum
1686 number of recursive calls we'll allow. After the call, reset it
1689 2002-04-21 Paul D. Smith <psmith@gnu.org>
1691 Modified to use latest autoconf (2.53), automake (1.6.1), and
1692 gettext (0.11.1). We're using gettext's new "external" support,
1693 to avoid including libintl source with GNU make.
1695 * README.cvs: New file. Explain how to build GNU make from CVS.
1697 * configure.in: Modify checking for the system glob library.
1698 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
1699 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
1700 etc. will manage it correctly). Set an automake conditional
1701 USE_LOCAL_GLOB to decide whether to compile the glob library.
1703 * getloadavg.c (main): Include make.h in the "TEST" program to
1706 * Makefile.am: Remove special rules for loadavg. Replace them
1707 with Automake capabilities for building extra programs.
1709 * signame.c: This file does nothing if the system provide
1710 strsignal(). If not, it implements strsignal(). If the system
1711 doesn't define sys_siglist, then we make our own; otherwise we use
1713 * signame.h: Removed.
1715 * main.c (main): No need to invoke signame_init(). Update copyright.
1717 * ABOUT-NLS: Removed.
1718 * gettext.c: Removed.
1719 * gettext.h: Get a simplified copy from the gettext package.
1721 * i18n/*.po: Moved to po/.
1724 * config/*: Created. Contains package configuration helper files.
1725 * config.guess, config.sub: Moved to config directory.
1727 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
1728 Rework to use new-style autoconf features. Use the "external"
1729 mode for gettext. Make the build.sh config file conditional on
1730 whether build.sh.in exists, to avoid autoconf errors.
1731 * acinclude.m4: Removed almost all macros as being obsolete.
1732 Rewrote remaining macros to use AC_DEFINE.
1733 * acconfig.h: Removed.
1735 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
1736 conditional to handle customs support. Remove special handling
1739 2002-04-20 Paul D. Smith <psmith@gnu.org>
1741 * function.c (func_call): Don't mark the argument variables $1,
1742 etc. as recursive. They've already been fully expanded so
1743 there's no need to do it again, and doing so strips escaped $'s.
1744 Reported by Sebastian Glita <glseba@yahoo.com>.
1746 * remake.c (notice_finished_file): Walk through double-colon
1747 entries via the prev field, not the next field!
1748 Reported by Greg McGary <greg@mcgary.org>.
1750 * main.c (main): If the user specifies -q and asks for a specific
1751 target which is a makefile, we got an assert. In that case it
1752 turns out we should continue normally instead.
1754 * i18n/de.po, i18n/fr.po: Installed an updated translation.
1756 * i18n/he.po: Installed a new translation.
1758 2002-01-07 Paul D. Smith <psmith@gnu.org>
1760 * i18n/es.po, i18n/ru.po: Installed an updated translation.
1762 2001-12-04 Paul D. Smith <psmith@gnu.org>
1764 * i18n/ja.po: Installed an updated translation.
1766 2001-09-06 Paul Eggert <eggert@twinsun.com>
1768 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
1769 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
1771 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
1773 (main): Get rid of any avoidable limit on stack size.
1775 2001-09-04 Paul D. Smith <psmith@gnu.org>
1777 * i18n/da.po: Installed an updated translation.
1779 2001-08-03 Paul D. Smith <psmith@gnu.org>
1781 * i18n/fr.po: Installed an updated translation.
1782 Resolves Debian bug #106720.
1784 2001-06-13 Paul D. Smith <psmith@gnu.org>
1786 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
1789 2001-06-11 Paul D. Smith <psmith@gnu.org>
1791 * i18n/ko.po: Installed a new translation.
1793 2001-05-06 Paul D. Smith <psmith@gnu.org>
1795 Modify the EINTR handling.
1797 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
1798 the way in which we manage the file descriptor/signal handler race
1799 trap to be more efficient.
1801 2001-05-06 Paul Eggert <eggert@twinsun.com>
1803 Restart almost all system calls that are interrupted, instead
1804 of worrying about EINTR. The lone exception is the read() for
1807 * configure.in (HAVE_SA_RESTART): New macro.
1808 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
1809 * main.c (main): Use SA_RESTART instead of the old,
1810 nonstandard SA_INTERRUPT.
1812 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
1813 * main.c (bsd_signal): New function or macro,
1814 if the implementation doesn't supply it.
1815 (The bsd_signal function will be in POSIX 1003.1-200x.)
1816 (HANDLESIG): Remove.
1817 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
1819 * make.h (EINTR_SET): Remove.
1820 (SA_RESTART): New macro.
1822 * arscan.c (ar_member_touch): Don't worry about EINTR.
1823 * function.c (func_shell): Likewise.
1824 * job.c (reap_children, free_child, new_job): Likewise.
1825 * main.c (main): Likewise.
1826 * remake.c (touch_file, name_mtime): Likewise.
1828 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
1829 if fstat failed with errno!=EINTR, the error was ignored.
1831 * job.c (set_child_handler_action_flags): New function.
1832 (new_job): Use it to temporarily clear the SIGCHLD action flags
1833 while reading the token.
1835 2001-05-02 Paul D. Smith <psmith@gnu.org>
1837 * job.c (start_job_command): Don't add define/endef per-line flags
1838 to the top-level flags setting.
1840 2001-04-03 Paul D. Smith <psmith@gnu.org>
1842 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
1843 bit on error, so check for odd return values, not non-0 return
1845 (VMS_get_member_info): Calculate the timezone differences correctly.
1846 Reported by John Fowler <jfowler@nyx.net>.
1849 2001-03-14 Paul D. Smith <psmith@gnu.org>
1851 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
1852 value before invoking define_variable().
1853 Reported by John Fowler <jfowler@nyx.net>.
1855 2001-02-07 Paul D. Smith <psmith@gnu.org>
1857 * read.c (record_target_var): If we reset the variable due to a
1858 command-line variable setting overriding it, turn off the "append"
1861 2001-01-17 Paul D. Smith <psmith@gnu.org>
1863 * variable.c (lookup_variable) [VMS]: When getting values from the
1864 environment, allocate enough space for the _value_ plus escapes,
1865 not enough space for the name plus escapes :-/.
1866 Reported by John Fowler <jfowler@nyx.net>.
1868 * remake.c (f_mtime): Removed the "***" prefix from the mod time
1869 warnings that make generates, so it doesn't look like an error.
1870 Reported by Karl Berry <karl@gnu.org>.
1873 Fix for PR/2020: Rework appended target-specific variables. I'm
1874 fairly confident this algorithm is finally correct.
1876 * expand.c (allocated_variable_append): Rewrite. Instead of
1877 expanding each appended variable then adding all the expanded
1878 strings together, we append all the unexpanded values going up
1879 through the variable set contexts, then expand the final result.
1880 This behaves just like non-target-specific appended variable
1881 values, while the old way didn't in various corner cases.
1882 (variable_append): New function: recursively append the unexpanded
1883 value of a variable, walking from the outermost variable scope to
1885 * variable.c (lookup_variable): Remove the code that looked up the
1886 variable set list if the found variable was "append". We don't
1888 (lookup_variable_in_set): Make this non-static so we can use it
1890 (try_variable_definition): Use lookup_variable_in_set() rather
1891 than faking out current_variable_set_list by hand (cleanup).
1892 * variable.h: Add a prototype for the now non-static
1893 lookup_variable_in_set().
1895 2000-11-17 Paul D. Smith <psmith@gnu.org>
1897 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
1898 WINDOWS32 port to assume timestamps can be up to 3 seconds away
1899 before throwing a fit.
1901 2000-11-17 Paul D. Smith <psmith@gnu.org>
1903 * read.c (readline): CRLF calculations had a hole, if you hit the
1904 buffer grow scenario just right. Reworked the algorithm to avoid
1905 the need for len or lastlen at all. Problem description with
1906 sample code chages provided by Chris Faylor <cgf@redhat.com>.
1908 2000-10-24 Paul D. Smith <psmith@gnu.org>
1910 * gettext.c (SWAP): Declare this with the prototype, otherwise
1911 some systems don't work (non-32-bit? Reported for Cray T3E).
1912 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
1914 2000-10-05 Paul D. Smith <psmith@gnu.org>
1916 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
1917 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
1919 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
1921 2000-09-22 Paul D. Smith <psmith@gnu.org>
1923 * gettext.c: Don't #define _GETTEXT_H here; we only include some
1924 parts of the real gettext.h here, and we expect to really include
1925 the real gettext.h later. If we keep this #define, it's ignored.
1927 2000-09-21 Paul D. Smith <psmith@gnu.org>
1929 * main.c (log_working_directory): Rework the text to use complete
1930 sentences, to make life simpler for the translators.
1932 2000-08-29 Paul D. Smith <psmith@gnu.org>
1934 * file.c (remove_intermediates): Print a debug message before we
1935 remove intermediate files, so the user (if she uses -d) knows
1938 2000-08-21 Paul D. Smith <psmith@gnu.org>
1940 * variable.c (try_variable_definition): Change how we handle
1941 target-specific append variable defns: instead of just setting the
1942 value, expand it as an append _but_ only within the current
1943 target's context. Otherwise we lose all but the last value if the
1944 variable is appended more than once within the current target
1945 context. Fixes PR/1831.
1947 2000-08-16 Paul D. Smith <psmith@gnu.org>
1949 * function.c (func_shell): Nul-terminate the buffer before
1950 printing an exec error message (just in case it's not!).
1951 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
1953 2000-07-25 Paul D. Smith <psmith@gnu.org>
1955 * job.c (construct_command_argv_internal): Add "~" to the list of
1956 sh_chars[] which disallow optimizing out the shell call.
1958 2000-07-23 Paul Eggert <eggert@twinsun.com>
1960 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
1961 supersedes --disable-nsec-timestamps.
1962 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
1963 * README: Remove --disable-nsec-timestamps.
1965 * filedef.h (struct file.low_resolution_time): New member.
1966 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
1967 * remake.c (update_file_1):
1968 Avoid spurious rebuilds due to low resolution time stamps,
1969 generalizing the earlier code that applied only to archive members.
1970 (f_mtime): Archive members always have low resolution time stamps.
1972 * configure.in: Remove --disable-nsec-timestamps, as this has
1973 been superseded by .LOW_RESOLUTION_TIME.
1975 2000-07-23 Paul Eggert <eggert@twinsun.com>
1977 * configure.in (enable_nsec_timestamps): Renamed from
1978 make_cv_nsec_timestamps, since enable/disable options
1979 shouldn't be cached.
1981 2000-07-23 Bruno Haible <haible@clisp.cons.org>
1982 and Paul Eggert <eggert@twinsun.com>
1984 * file.c (file_timestamp_now):
1985 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
1986 so that clock_gettime is not linked unless needed.
1988 * filedef.h (FILE_TIMESTAMP_HI_RES):
1989 Remove definition; "configure" now does this.
1991 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
1992 to before high resolution file timestamp check,
1993 since that check now uses uintmax_t.
1994 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
1995 high resolution file timestamps.
1996 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
1997 so that we don't link in clock_gettime unnecessarily.
1999 2000-07-17 Paul D. Smith <psmith@gnu.org>
2001 * i18n/ja.po: New version of the translation file.
2003 2000-07-07 Paul D. Smith <psmith@gnu.org>
2005 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
2006 the offset calculation.
2007 (name_mtime): Replace EINTR test with EINTR_SET macro.
2009 2000-07-07 Paul Eggert <eggert@twinsun.com>
2013 * remake.c (update_file_1):
2014 Avoid spurious rebuilds of archive members due to their
2015 timestamp resolution being only one second.
2016 (f_mtime): Avoid spurious warnings of timestamps in the future due to
2017 the clock's resolution being lower than file timestamps'.
2018 When warning about future timestamps, report only the discrepancy,
2019 not the absolute value of the timestamp and the current time.
2021 * file.c (file_timestamp_now): New arg RESOLUTION.
2022 * filedef.h (file_timestamp_now): Likewise.
2023 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
2025 2000-07-05 Paul D. Smith <psmith@gnu.org>
2027 * variable.c (lookup_variable) [VMS]: Remove vestigial references
2028 to listp. Fixes PR/1793.
2030 2000-06-26 Paul Eggert <eggert@twinsun.com>
2032 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
2034 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
2036 * remake.c (f_mtime): Remove unused var memtime.
2038 2000-06-25 Martin Buchholz <martin@xemacs.org>
2040 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
2041 Ran spell-check on make.texinfo.
2043 2000-06-23 Paul D. Smith <psmith@gnu.org>
2045 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
2046 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
2047 * make.h: Define these macros.
2049 * Version 3.79.1 released.
2051 * configure.in: Add a new option, --disable-nsec-timestamps, to
2052 avoid using sub-second timestamps on systems that support it. It
2053 can lead to problems, e.g. if your makefile relies on "cp -p".
2054 * README.template: Document the issue with "cp -p".
2056 * config.guess, config.sub: Updated.
2060 See ChangeLog.2, available in the CVS repository at:
