1 2005-05-13 Paul D. Smith <psmith@gnu.org>
3 Implement "if... else if... endif" syntax.
5 * read.c (eval): Push all checks for conditional words ("ifeq",
6 "else", etc.) down into the conditional_line() function.
7 (conditional_line): Rework to allow "else if..." clause. New
8 return value -2 for lines which are not conditionals. The
9 ignoring flag can now also be 2, which means "already parsed a
10 true branch". If that value is seen no other branch of this
11 conditional can be considered true. In the else parsing if there
12 is extra text after the else, invoke conditional_line()
13 recursively to see if it's another conditional. If not, it's an
14 error. If so, raise the conditional value to this level instead
15 of creating a new conditional nesting level. Special check for
16 "else" and "endif", which aren't allowed on the "else" line.
17 * doc/make.texi (Conditional Syntax): Document the new syntax.
19 2005-05-09 Paul D. Smith <psmith@gnu.org>
21 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
22 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
23 recurses to the w32 directory, even on non-Windows systems. Use
24 the method suggested in the automake manual.
25 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
26 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
28 2005-05-07 Paul D. Smith <psmith@gnu.org>
30 * main.c (die): If we're dying with a fatal error (not that a
31 command has failed), write back any leftover tokens before we go.
33 * job.c (set_child_handler_action_flags): If there are jobs
34 waiting for the load to go down, set an alarm to go off in 1
35 second. This allows us to wake up from a potentially long-lasting
36 read() and start a new job if the load has gone down. Turn it off
37 after the read.
38 (job_noop): Dummy signal handler function.
39 (new_job): Invoke it with the new semantics.
41 * docs/make.texi: Document secondary expansion. Various cleanups
42 and random work.
44 2005-05-03 Paul D. Smith <psmith@gnu.org>
46 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
47 the targets which are to ultimately be made are called "goals";
48 see the GNU make manual. Also, MAKECMDGOALS, etc.
50 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
51 .DEFAULT_GOAL, and default_target_name to default_goal_name.
52 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
54 2005-05-02 Paul D. Smith <psmith@gnu.org>
56 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
57 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
58 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
59 functions to vmsjobs.c. #include it into jobs.c.
61 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
62 jobserver tokens. I found that this happens when an exported
63 recursive variable contains a $(shell ...) function reference: in
64 this situation we could "forget" to write back a token.
66 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
67 we have. It's not reliable to depend on the number of children in
68 our linked list so keep a separate count.
69 (new_job): Check jobserver_tokens rather than children &&
70 waiting_jobs. Increment jobserver_tokens when we get one.
71 (free_child): If jobserver_tokens is 0, internal error. If it's
72 >1, write a token back to the jobserver pipe (we don't write a
73 token for the "free" job). Decrement jobserver_tokens.
75 * main.c: Add variable master_job_slots.
76 (main): Set it to hold the number of jobs requested if we're the
77 master process, when using the jobserver.
78 (die): Sanity checks: first test jobserver_tokens to make sure
79 this process isn't holding any tokens we didn't write back.
80 Second, if master_job_slots is set count the tokens left in the
81 jobserver pipe and ensure it's the same as master_job_slots (- 1).
83 2005-04-24 Paul D. Smith <psmith@gnu.org>
85 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
86 with -l# can lose jobserver tokens, because waiting jobs are not
87 consulted properly when checking for the "free" token.
89 * job.c (free_child): Count waiting_jobs as having tokens.
90 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
91 handle jobs waiting for the load to drop.
93 2005-04-23 Paul D. Smith <psmith@gnu.org>
95 * main.c (main): Be careful to not core if a variable setting in
96 the environment doesn't contain an '='. This is illegal but can
97 happen in broken setups.
98 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
100 2005-04-12 Paul D. Smith <psmith@gnu.org>
102 The second expansion feature causes significant slowdown. Timing
103 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
104 read the makefile before the feature, to 11+s to do the same
105 operations after the feature. Additionally, memory usage
106 increased drastically. To fix this I added some intelligence that
107 avoids the overhead of the second expansion unless it's required.
109 * dep.h: Add a new boolean field, need_2nd_expansion.
111 * read.c (eval): When creating the struct dep for the target,
112 check if the name contains a "$"; if so set need_2nd_expansion to 1.
113 (record_files): If there's a "%" in a static pattern rule, it gets
114 converted to "$*" so set need_2nd_expansion to 1.
116 * file.c (expand_deps): Rework to be more efficient. Only perform
117 initialize_file_variables(), set_file_variables(), and
118 variable_expand_for_file() if the need_2nd_expansion is set.
120 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
121 (pattern_search): Ditto.
122 * main.c (handle_non_switch_argument): Ditto.
123 (main): Ditto.
124 * read.c (read_all_makefiles): Ditto.
125 (eval_makefile): Ditto.
127 2005-04-07 Paul D. Smith <psmith@gnu.org>
129 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
130 * variable.c (sync_Path_environment): Ditto.
131 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
133 * main.c (main): Define the .FEATURES variable.
134 * NEWS: Announce .FEATURES.
135 * doc/make.texi (Special Variables): Document .FEATURES.
137 * remake.c (check_dep): If a file is .PHONY, update it even if
138 it's marked intermediate. Fixes Savannah bug #12331.
140 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
142 * file.c (expand_deps): Factor out the second expansion and
143 prerequisite line parsing logic from snap_deps().
145 * file.c (snap_deps): Use expand_deps(). Expand and parse
146 prerequisites of the .SUFFIXES special target first. Fixes
147 Savannah bug #12320.
149 2005-03-13 Paul D. Smith <psmith@gnu.org>
151 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
152 Zaretskii.
154 2005-03-11 Paul D. Smith <psmith@gnu.org>
156 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
157 available, not undefined (from Earnie Boyd).
159 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
161 * implicit.c (pattern_search): Mark an intermediate target as
162 precious if it happened to be a prerequisite of some (other)
163 target. Fixes Savannah bug #12267.
165 2005-03-09 Paul D. Smith <psmith@gnu.org>
167 * read.c (eval_makefile): Add alloca(0).
168 (eval_buffer): Ditto.
170 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
172 * main.c (main): Use o_file instead of o_default when defining
173 the .DEFAULT_TARGET special variable.
174 * read.c (eval): Use define_variable_global() instead of
175 define_variable() when setting new value for the .DEFAULT_TARGET
176 special variable. Fixes Savannah bug #12266.
178 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
180 * imlicit.c (pattern_search): Mark files for which an implicit
181 rule has been found as targets. Fixes Savannah bug #12202.
183 2005-03-04 Paul D. Smith <psmith@gnu.org>
185 * AUTHORS: Update.
186 * doc/make.texi (Automatic Variables): Document $|.
188 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
190 * read.c (record_files): Instead of substituting % with
191 actual stem value in dependency list replace it with $*.
192 This fixes stem triple expansion bug.
194 * implicit.c (pattern_search): Copy stem to a separate
195 buffer and make it a properly terminated string. Assign
196 this buffer instead of STEM (which is not terminated) to
197 f->stem. Instead of substituting % with actual stem value
198 in dependency list replace it with $*. This fixes stem
199 triple expansion bug.
201 2005-03-01 Paul D. Smith <psmith@gnu.org>
203 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
204 on Windows, as it takes a handle not a pid. Just exit.
205 Fix from patch #3679, provided by Alessandro Vesely.
207 * configure.in: Update check for sys_siglist[] from autoconf manual.
208 * signame.c (strsignal): Update to use the new autoconf macro.
210 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
212 * read.c (record_files): Add a check for the list of prerequisites
213 of a static pattern rule being empty. Fixes Savannah bug #12180.
215 2005-02-28 Paul D. Smith <psmith@gnu.org>
217 * doc/make.texi (Text Functions): Update docs to allow the end
218 ordinal for $(wordlist ...) to be 0.
219 * function.c (func_wordlist): Fail if the start ordinal for
220 $(wordlist ...) is <1. Matches documentation.
221 Resolves Savannah support request #103195.
223 * remake.c (update_goal_chain): Fix logic for stopping in -q:
224 previously we were stopping when !-q, exactly the opposite. This
225 has been wrong since version 1.34, in 1994!
226 (update_file): If we got an error don't break out to run more
227 double-colon rules: just return immediately.
228 Fixes Savannah bug #7144.
230 2005-02-27 Paul D. Smith <psmith@gnu.org>
232 * misc.c (end_of_token): Make argument const.
233 * make.h: Update prototype.
235 * function.c (abspath, func_realpath, func_abspath): Use
236 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
237 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
238 * read.c (record_files): Ditto.
239 * variable.c (do_variable_definition): Ditto.
241 * function.c (func_error): Create a new function $(info ...) that
242 simply prints the message to stdout with no extras.
243 (function_table_init): Add new function to the table.
244 * NEWS: Add $(info ...) reference.
245 * doc/make.texi (Make Control Functions): Document it.
247 New feature: if the system supports symbolic links, and the user
248 provides the -L/--check-symlink-time flag, then use the latest
249 mtime between the symlink(s) and the target file.
251 * configure.in (MAKE_SYMLINKS): Check for lstat() and
252 readlink(). If both are available, define MAKE_SYMLINKS.
253 * main.c: New variable: check_symlink_flag.
254 (usage): Add a line for -L/--check-symlink-times to the help string.
255 (switches): Add -L/--check-symlink-times command line argument.
256 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
257 print a warning and disable it again.
258 * make.h: Declare check_symlink_flag.
259 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
260 if the file is a symlink then check each link in the chain and
261 choose the NEWEST mtime we find as the mtime for the file. The
262 newest mtime might be the file itself!
263 * NEWS: Add information about this new feature.
264 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
266 Avoid core dumps described in Savannah bug # 12124:
268 * file.c: New variable snapped_deps remember whether we've run
269 snap_deps().
270 (snap_deps): Set it.
271 * filedef.h: Extern it.
272 * read.c (record_files): Check snapped_deps; if it's set then
273 we're trying to eval a new target/prerequisite relationship from
274 within a command script, which we don't support. Fatal.
276 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
278 Implementation of the .DEFAULT_TARGET special variable.
280 * read.c (eval): If necessary, update default_target_name when
281 reading rules.
282 * read.c (record_files): Update default_target_file if
283 default_target_name has changed.
284 * main.c (default_target_name): Define.
285 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
286 default_target_name is set use default_target_file as a root
287 target to make.
288 * filedef.h (default_target_name): Declare.
289 * dep.h (free_dep_chain):
290 * misc.c (free_dep_chain): Change to operate on struct nameseq
291 and change name to free_ns_chain.
292 * file.c (snap_deps): Update to use free_ns_chain.
294 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
296 Implementation of the second expansion in explicit rules,
297 static pattern rules and implicit rules.
299 * read.c (eval): Refrain from chopping up rule's dependencies.
300 Store them in a struct dep as a single dependency line. Remove
301 the code that implements SySV-style automatic variables.
303 * read.c (record_files): Adjust the code that handles static
304 pattern rules to expand all percents instead of only the first
305 one. Reverse the order in which dependencies are stored so that
306 when the second expansion reverses them again they appear in
307 the makefile order (with some exceptions, see comments in
308 the code). Remove the code that implements SySV-style automatic
309 variables.
311 * file.c (snap_deps): Implement the second expansion and chopping
312 of dependency lines for explicit rules.
314 * implicit.c (struct idep): Define an auxiliary data type to hold
315 implicit rule's dependencies after stem substitution and
316 expansion.
318 * implicit.c (free_idep_chain): Implement.
320 * implicit.c (get_next_word): Implement helper function for
321 parsing implicit rule's dependency lines into words taking
322 into account variable expansion requests. Used in the stem
323 splitting code.
325 * implicit.c (pattern_search): Implement the second expansion
326 for implicit rules. Also fixes bug #12091.
328 * commands.h (set_file_variables): Declare.
329 * commands.c (set_file_variables): Remove static specifier.
331 * dep.h (free_dep_chain): Declare.
332 * misc.c (free_dep_chain): Implement.
334 * variable.h (variable_expand_for_file): Declare.
335 * expand.c (variable_expand_for_file): Remove static specifier.
337 * make.h (strip_whitespace): Declare.
338 * function.c (strip_whitespace): Remove static specifier.
340 2005-02-26 Paul D. Smith <psmith@gnu.org>
342 * main.c (main): Check for ferror() when reading makefiles from stdin.
343 Apparently some shells in Windows don't close pipes properly and
344 require this check.
346 2005-02-24 Jonathan Grant <jg@jguk.org>
348 * configure.in: Add MinGW configuration options, and extra w32 code
349 directory.
350 * Makefile.am: Add MinGW configuration options, and extra w32 code
351 directory.
352 * main.c: Determine correct program string (after last \ without .exe).
353 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
354 type fix x2
355 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
356 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
357 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
358 environment support.
360 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
362 * function.c (func_shell): When initializing error_prefix, check
363 that reading file name is not null. This fixes long-standing
364 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
366 2005-02-09 Paul D. Smith <psmith@gnu.org>
368 * maintMakefile: Update the CVS download URL to simplify them.
369 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
370 downloading the .texi files from Savannah now.
372 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
374 * main.c (handle_non_switch_argument): Only add variables to
375 command_variables if they're not already there: duplicate settings
376 waste space and can be confusing to read.
378 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
379 this header is never included by non-WINDOWS32 code, and it
380 requires <config.h> to define which isn't always included first.
382 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
383 testing MINGW32 versions.
385 * main.c (log_working_directory): flush stdout to be sure the WD
386 change is printed before any stderr messages show up.
388 2005-02-01 Paul D. Smith <psmith@gnu.org>
390 * maintMakefile (po_repo): Update the GNU translation site URL.
392 2004-12-01 Paul D. Smith <psmith@gnu.org>
394 * main.c (main): Change char* env_shell to struct variable shell_var.
395 * variable.c (target_environment): Use new shell_var.
397 2004-11-30 Paul D. Smith <psmith@gnu.org>
399 * configure.in: The old way we avoided creating build.sh from
400 build.sh.in before build.sh.in exists doesn't work anymore; we
401 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
402 the help!). This also keeps automake from complaining.
403 * Makefile.am (README): Add a dummy target so automake won't
404 complain that this file doesn't exist when we checkout from CVS.
405 * maintMakefile (.dep_segment): Rewrite this rule since newer
406 versions of automake don't provide DEP_FILES.
408 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
410 Implementation of `realpath' and `abspath' built-in functions.
412 * configure.in: Check for realpath.
413 * function.c (abspath): Return an absolute file name that does
414 not contain any `.' or `..' components, nor repeated `/'.
415 * function.c (func_abspath): For each name call abspath.
416 * function.c (func_realpath): For each name call realpath
417 from libc or delegate to abspath if realpath is not available.
418 * doc/make.texi (Functions for File Names): Document new functions.
419 * doc/make.texi (Quick Reference): Ditto.
421 2004-11-28 Paul D. Smith <psmith@gnu.org>
423 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
424 arguments. Fixes bug #10252.
426 Fix for bug #1276: Handle SHELL according to POSIX requirements.
428 * main.c (main): Set SHELL to v_noexport by default. Remember the
429 original environment setting of SHELL in the env_shell variable.
430 * main.h: Export new env_shell variable.
431 * variable.c (target_environment): If we find a v_noexport
432 variable for SHELL, add a SHELL variable with the env_shell value.
433 * doc/make.texi (Quick Reference): Document the POSIX behavior.
434 * doc/make.texi (Variables/Recursion): Ditto.
436 2004-11-28 Paul D. Smith <psmith@gnu.org>
438 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
439 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
440 Patch by Alessandro Vesely.
442 2004-11-12 Paul D. Smith <psmith@gnu.org>
444 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
445 the command line if it's inside a string.
446 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
448 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
450 * function.c (func_lastword): New function: return last word
451 from the list of words.
452 * doc/make.texi: Document $(lastword ). Fix broken links in
453 Quick Reference section.
455 2004-10-06 Paul D. Smith <psmith@gnu.org>
457 Apply patch from Alessandro Vesely, provided with bug # 9748.
458 Fix use of tmpnam() to work with Borland C.
460 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
461 construction of a temporary filename, and call new function
462 create_batch_filename().
463 (create_batch_filename) [WINDOWS32]: New function to create a
464 temporary filename.
466 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
468 * read.c (record_target_var): Expand simple pattern-specific
469 variable.
470 * variable.c (initialize_file_variables): Do not expand simple
471 pattern-specific variable.
473 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
475 * remake.c (update_file_1): When rebuilding makefiles inherit
476 dontcare flag from a target that triggered update.
478 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
480 * variable.c (initialize_file_variables): Mark pattern-specific
481 variable as a per-target and copy export status.
483 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
485 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
487 * implicit.c (pattern_search): When considering an implicit rule's
488 prerequisite check that it is actually a target rather then
489 just an entry in the file hashtable.
491 2004-09-21 Paul D. Smith <psmith@gnu.org>
493 * read.c (readstring): Fix some logic errors in backslash handling.
494 (eval): Remove some unnecessary processing in buffer handling.
495 (record_target_var): Assert that parse_variable_definition() succeeded.
496 Reported by: Markus Mauhart <qwe123@chello.at>.
498 * misc.c: Removed the sindex() function. All instances of this
499 function were trivially replaceable by the standard strstr()
500 function, and that function will always have better (or certainly
501 no worse) performance than the very simple-minded algorithm
502 sindex() used. This can matter with complex makefiles.
503 * make.h: Remove the prototype for sindex().
504 * function.c (subst_expand): Convert sindex() call to strstr().
505 This means we no longer need to track the TLEN value so remove that.
506 (func_findstring): Convert sindex() to strstr().
507 * commands.c (chop_commands): Convert sindex() calls to strstr().
508 Suggested by: Markus Mauhart <qwe123@chello.at>.
510 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
511 idea behind Savannah Patch #3144 from david.baird@homemail.com.
512 If SHELL is set to CMD.EXE then assume it's batch-mode and
513 non-unixy. I wrote the code differently from the patch, though,
514 to make it safer. This also resolves bug #9174.
516 2004-09-20 Paul D. Smith <psmith@gnu.org>
518 * expand.c (variable_expand_string): Modify to invoke
519 patsubst_expand() instead of subst_expand(); the latter didn't
520 handle suffix patterns correctly.
521 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
522 was used only from variable_expand_string() and is no longer used
523 there.
524 (func_subst): Ditto, on call to subst_expand().
525 (patsubst_expand): Require the percent pointers to point to the
526 character after the %, not to the % itself.
527 * read.c (record_files): New call criteria for patsubst_expand().
528 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
529 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
531 2004-09-19 Paul D. Smith <psmith@gnu.org>
533 * function.c (subst_expand): Fix a check in by_word: look for a
534 previous blank if we're beyond the beginning of the string, not
535 the beginning of the word.
536 Bugs reported by Markus Mauhart <qwe123@chello.at>.
538 2004-05-16 Paul D. Smith <psmith@gnu.org>
540 * remake.c (update_goal_chain): Change the argument specifying
541 whether we're rebuilding makefiles to be a global variable,
542 REBUILDING_MAKEFILES.
543 (complain): Extract the code that complains about no rules to make
544 a target into a separate function.
545 (update_file_1): If we tried to rebuild a file during the makefile
546 rebuild phase and it was dontcare, then no message was printed.
547 If we then try to build the same file during the normal build,
548 print a message this time.
549 (remake_file): Don't complain about un-remake-able files when
550 we're rebuilding makefiles.
552 2004-05-11 Paul D. Smith <psmith@gnu.org>
554 * job.c (construct_command_argv_internal): OS/2 patches from
555 Andreas Buening <andreas.buening@nexgo.de>.
557 2004-05-10 Paul D. Smith <psmith@gnu.org>
559 * remake.c (update_file): Don't walk the double-colon chain unless
560 this is a double-colon rule. Fix suggested by Boris Kolpackov
561 <boris@kolpackov.net>.
563 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
564 * readme.vms: New section describing OpenVMS support and issues.
565 * default.c (default_variables): Add support for IA64.
566 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
567 without some privilege aborts make with the error
568 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
569 pressing Ctrl+Y and the input device is no terminal. The change
570 catches this error and just continues.
572 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
574 2004-04-25 Paul D. Smith <psmith@gnu.org>
576 * commands.c (set_file_variables): Set $< properly in the face of
577 order-only prerequisites.
578 Patch from Boris Kolpackov <boris@kolpackov.net>
580 2004-04-21 Bob Byrnes <byrnes@curl.com>
582 * main.c (main): Notice failures to remake makefiles.
584 2004-03-28 Paul D. Smith <psmith@gnu.org>
586 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
588 * job.c: No default shell for RISC OS.
589 (load_too_high): Hard-code the return to 1.
590 (construct_command_argv_internal): No sh_chars or sh_cmds.
591 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
593 2004-03-20 Paul D. Smith <psmith@gnu.org>
595 * variable.c (do_variable_definition): Don't append from the
596 global set if a previous non-appending target-specific variable
597 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
598 (with fix).
600 * expand.c (reference_variable): Don't give up on variables with
601 no value that have the target-specific append flag set: they might
602 have a value after all. Reported by Oliver Schmidt
603 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
604 <nikulin@dx1cmd.inp.nsk.su>.
606 * rule.c (count_implicit_rule_limits): Don't delete patterns which
607 refer to absolute pathnames in directories that don't exist: some
608 portion of the makefile could create those directories before we
609 match the pattern. Fixes bugs #775 and #108.
611 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
613 * main.c (main): Free makefile_mtimes if we have any.
614 * README.W32.template: Update documentation for the current status
615 of the MS-Windows port.
616 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
617 environment variable is sometimes already defined which causes the
618 build to fail.
619 * main.c (debug_signal_handler): Only define this function if
620 SIGUSR1 is available.
622 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
624 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
625 * README.OS2.template: Documentation updates.
626 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
627 link line for safety.
628 * maintMakefile (build.sh.in): Remove an extraneous ")".
629 * job.c (child_execute_job): Close saved FDs.
630 * job.c (exec_command) [OS/2]: exec_command(): If the command
631 can't be exec'ed and if the shell is not Unix-sh, then try again
632 with argv = { "cmd", "/c", ... }. Normally, this code is never
633 reached for the cmd shell unless the command really doesn't exist.
634 (construct_command_argv_internal) [OS/2]: The code for cmd
635 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
636 The CMD builtin commands are case insensitive so use strcasecmp().
638 2004-03-19 Paul D. Smith <psmith@gnu.org>
640 * read.c (do_define): Re-order line counter increment so the count
641 is accurate (we were losing one line per define). Reported by
642 Dave Yost <Dave@Yost.com>.
644 2004-03-06 Paul D. Smith <psmith@gnu.org>
646 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
647 compiler.
648 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
649 * misc.c (message,error,fatal): Ditto.
650 * configh.dos.template: Define HAVE_ANSI_COMPILER.
651 * config.h.W32.template: Ditto.
652 * config.h-vms.template: Ditto.
653 * config.ami.template: Ditto.
655 2004-03-04 Paul D. Smith <psmith@gnu.org>
657 * README.template: Add a note about broken /bin/sh on SunOS
658 4.1.3_U1 & 4.1.4. Fix up Savannah links.
660 * misc.c (message, error, fatal): Don't use "..." if we're using
661 varargs. ansi2knr should handle this but it doesn't work: it
662 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
663 done. On many systems (SunOS for example) va_dcl is a #define.
664 So, force the use of the non-"..." version on pre-ANSI compilers.
666 * maintMakefile (sign-dist): Create some rules to help automate
667 the new GNU ftp upload method.
669 2004-02-24 Paul D. Smith <psmith@gnu.org>
671 * config.h.W32.template: Add HAVE_STDARG_H
672 * config.h-vms.template: Ditto.
673 * config.ami.template: Ditto.
675 2004-02-23 Jonathan Grant <jg-make@jguk.org>
677 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
678 * build_w32.bat: Remove extra "+".
680 2004-02-23 Paul D. Smith <psmith@gnu.org>
682 * make.h: Create an UNUSED macro to mark unused parameters.
683 * (many): Clean up warnings by applying UNUSED, fixing
684 signed/unsigned incompatibilities, etc.
686 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
687 autoconf warnings.
688 * filedef.h: Name the command_state enumeration.
689 * file.c (set_command_state): Use the enumeration in the function
690 argument.
692 * configure.in: Explicitly set SET_MAKE to empty, to disable
693 MAKE=make even when no make already exists. Fix bug #3823.
695 2004-02-22 Paul D. Smith <psmith@gnu.org>
697 * maintMakefile: Perl script to clean up all non-CVS files. Use
698 it on all the subdirectories for the cvs-clean target.
700 * main.c (decode_switches): Require non-empty strings for all our
701 string command-line options. Fixes Debian bug # 164165.
703 * configure.in: Check for stdarg.h and varargs.h.
704 * make.h (USE_VARIADIC): Set this if we can use variadic functions
705 for printing messages.
706 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
707 (message): Ditto.
708 (error): Ditto.
709 (fatal): Ditto.
711 A number of patches for OS/2 support from Andreas Buening
712 <andreas.buening@nexgo.de>:
714 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
715 disable the SIGCHLD handler.
716 (reap_children) [OS/2]: Remove special handling of job_rfd.
717 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
718 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
719 * main.c (main) [OS/2]: Special handling for paths in OS/2.
720 * configure.in [OS/2]: Force SA_RESTART for OS/2.
721 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
722 systems.
724 2004-02-21 Paul D. Smith <psmith@gnu.org>
726 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
727 <mail@kristov.de> reports that if process_begin() fails we don't
728 handle the error condition correctly in all cases.
729 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
730 to have a newline on the message.
732 * job.c (construct_command_argv_internal): Add "test" to UNIX
733 sh_cmds[]. Fixes Savannah bug # 7606.
735 2004-02-04 Paul D. Smith <psmith@gnu.org>
737 * job.c (vms_handle_apos) [VMS]: Fix various string handling
738 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
739 Hartmut Becker <Hartmut.Becker@hp.com>.
741 2004-01-21 Paul D. Smith <psmith@gnu.org>
743 * job.c (load_too_high): Implement an algorithm to control the
744 "thundering herd" problem when using -l to control job creation
745 via the load average. The system only recomputes the load once a
746 second but we can start many jobs in a second. To solve this we
747 keep track of the number of jobs started in the last second and
748 apply a weight to try to guess what a correct load would be.
749 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
750 Also fixes bug #4693.
751 (reap_children): Decrease the job count for this second.
752 (start_job_command): Increase the job count for this second.
754 * read.c (conditional_line): Expand the text after ifn?def before
755 checking to see if it's a single word. Fixes bug #7257.
757 2004-01-09 Paul D. Smith <psmith@gnu.org>
759 * file.c (print_file): Recurse to print all targets in
760 double-colon rules. Fixes bug #4518, reported (with patch) by
761 Andrew Chatham <chatham@google.com>.
763 2004-01-07 Paul D. Smith <psmith@gnu.org>
765 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
766 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
767 AC_FUNC_SETVBUF_REVERSED.
769 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
770 (MAKE Variable): Fix Savannah bug #4898.
772 * job.c (construct_command_argv_internal): Add "!" to the list of
773 shell escape chars. POSIX sh allows it to appear before a
774 command, to negate the exit code. Fixes bug #6404.
776 * implicit.c (pattern_search): When matching an implicit rule,
777 remember which dependencies have the ignore_mtime flag set.
778 Original fix provided in Savannah patch #2349, by Benoit
779 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
781 2003-11-22 Paul D. Smith <psmith@gnu.org>
783 * README.W32.template (Outputs): Clarification on -j with
784 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
785 <jg-make@jguk.org>.
787 2003-11-02 Paul D. Smith <psmith@gnu.org>
789 * function.c (func_if): Strip all the trailing whitespace from the
790 condition, then don't expand it. Fixed bug # 5798.
792 * expand.c (recursively_expand_for_file): If we're expanding a
793 variable with no file context, then use the variable's context.
794 Fixes bug # 6195.
796 2003-10-21 Paul D. Smith <psmith@gnu.org>
798 * main.c (log_working_directory): Add newlines to printf()s.
800 * README.cvs: Add a note to ignore warnings during autoreconf.
802 * maintMakefile (po_repo): Set a new URL for PO file updates.
803 (get-config/config.guess get-config/config.sub): Get these files
804 from the Savannah config project instead of ftp.gnu.org.
806 2003-10-05 Paul Eggert <eggert@twinsun.com>
808 * main.c (main): Avoid potential subscript error if environ has
809 short strings.
811 2003-08-22 Paul D. Smith <psmith@gnu.org>
813 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
814 systems which don't yet implement the C89 standard :-/.
816 2003-07-18 Paul D. Smith <psmith@gnu.org>
818 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
819 [WINDOWS32]: Initialize hash.
821 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
823 * dir.c (read_dirstream): Provide a workaround for broken versions of
824 the MinGW dirent structure.
826 2003-05-30 Earnie Boyd <earnie@users.sf.net>
828 * w32/include/dirent.h: Add __MINGW32__ filter.
830 2003-05-30 Earnie Boyd <earnie@users.sf.net>
832 * make.h: Add global declaration of *make_host.
833 * main.c (print_usage): Remove local declaration of *make_host.
834 (print_version): Display "This program built for ..." after Copyright
835 notice.
837 2003-05-30 Earnie Boyd <earnie@users.sf.net>
839 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
840 execution of "makeinfo --html make.texi".
842 2003-04-30 Paul D. Smith <psmith@gnu.org>
844 * build.template: Make some changes to maybe allow this script to
845 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
847 * README.OS2.template: New file for OS/2 support. Original
848 contributed by Andreas Buening.
849 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
850 DOS-style paths.
852 2003-04-19 Paul D. Smith <psmith@gnu.org>
854 Fix bug #1405: allow a target to match multiple pattern-specific
855 variables.
857 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
858 variable.c, where they've always belonged.
859 * rule.h: Move the prototypes and struct pattern_var as well.
860 * variable.c (initialize_file_variables): Invoke
861 lookup_pattern_var() in a loop, until no more matches are found.
862 If a match is found, create a new variable set for the target's
863 pattern variables. Then merge the contents of each matching
864 pattern variable set into the target's pattern variable set.
865 (lookup_pattern_var): Change this function to be usable
866 in a loop. It takes a starting position: if NULL, start at the
867 beginning; if non-NULL, start with the pattern variable after that
868 position, and return the next matching pattern.
869 (create_pattern_var): Create a unique instance of
870 pattern-specific variables for every definition in the makefile.
871 Don't combine the same pattern together. This allows us to
872 process the variable handling properly even when the same pattern
873 is used multiple times.
874 (parse_variable_definition): New function: break out the parsing
875 of a variable definition line from try_variable_definition.
876 (try_variable_definition): Call parse_variable_definition to
877 parse.
878 (print_variable_data_base): Print out pattern-specific variables.
879 * variable.h (struct variable): Remember when a variable is
880 conditional. Also remember its flavor.
881 (struct pattern_var): Instead of keeping a variable set, we just
882 keep a single variable for each pattern.
883 * read.c (record_target_var): Each pattern variable contains only a
884 single variable, not a set, so create it properly.
885 * doc/make.texi (Pattern-specific): Document the new behavior.
887 2003-04-17 Paul D. Smith <psmith@gnu.org>
889 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
890 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
891 file/directory naming rules for VMS so I can't tell whether this
892 is correct or not.
894 2003-04-09 Paul D. Smith <psmith@gnu.org>
896 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
897 DOS-style pathnames: backslash separators and drive specifiers.
899 2003-03-28 Paul D. Smith <psmith@gnu.org>
901 * file.c (snap_deps): If .SECONDARY with no targets is given, set
902 the intermediate flag on all targets. Fixes bug #2515.
904 2003-03-24 Paul D. Smith <psmith@gnu.org>
906 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
907 Upgrade to autoconf 2.57 and automake 1.7.3.
909 * job.c: More OS/2 changes from Andreas Buening.
911 * file.c (print_file): Fix variable initialization.
912 Fixes bug #2892.
914 * remake.c (notice_finished_file):
916 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
917 some calls (like readdir()) return NULL in valid situations
918 without resetting errno. Fixes bug #2846.
920 2003-02-25 Paul D. Smith <psmith@gnu.org>
922 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
924 * job.c (_is_unixy_shell) [OS/2]: New function.
925 Set default shell to /bin/sh.
926 (reap_children): Close the job_rfd pipe here since we don't use a
927 SIGCHLD handler.
928 (set_child_handler_action_flags): define this to empty on OS/2.
929 (start_job_command): Close the jobserver pipe and use
930 child_execute_job() instead of fork/exec.
931 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
932 rather than exec'ing, then reconfigure stdin/stdout.
933 (exec_command): Rewrite to use spawn instead of exec. Return the
934 PID of the child.
936 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
937 in DOS. Handle the TEMP environment variable as in DOS. Don't
938 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
939 use -j in DOS mode. Use child_execute_job() instead of
940 exec_command().
942 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
943 spawn() instead.
945 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
946 prototypes that return values.
948 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
950 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
951 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
952 for OS/2.
953 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
954 DOS paths.
956 2003-02-24 Paul D. Smith <psmith@gnu.org>
958 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
959 * job.c (child_execute_job) [VMS]: New code for handling spawn().
960 (child_execute_job) [VMS]: Handle error status properly.
961 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
963 * function.c (func_shell): Use EINTRLOOP() while reading from the
964 subshell pipe (Fixes bug #2502).
965 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
966 jobserver pipe.
967 * main.c (main): Ditto.
969 2003-01-30 Paul D. Smith <psmith@gnu.org>
971 * read.c (eval): eval() was not fully reentrant, because the
972 collapsed buffer was static. Change it to be an automatic
973 variable so that eval() can be invoked recursively.
974 Fixes bug # 2238.
975 (eval): Apply patch # 1022: fix memory reference error on long
976 target-specific variable lines.
977 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
979 * function.c (check_numeric): Combine the is_numeric() function
980 into this function, since it's only called from one place.
981 Constify this function. Have it print the incorrect string in the
982 error message. Fixes bug #2407.
983 (strip_whitespace): Constify.
984 (func_if): Constify.
985 * expand.c (expand_argument): Constify.
987 2003-01-29 Paul D. Smith <psmith@gnu.org>
989 Fix bug # 2169, also reported by other people on various systems.
991 * make.h: Some systems, such as Solaris and PTX, do not fully
992 implement POSIX-compliant SA_RESTART functionality; important
993 system calls like stat() and readdir() can still fail with EINTR
994 even if SA_RESTART has been set on the signal handler. So,
995 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
996 EINTR for system calls which return -1 or 0 (NULL), respectively,
997 on error.
998 Also, remove the old atomic_stat()/atomic_readdir() and
999 HAVE_BROKEN_RESTART handling.
1001 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
1003 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
1004 * remake.c (touch_file): Ditto.
1006 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
1007 * read.c (construct_include_path): Ditto.
1008 * remake.c (name_mtime): Ditto.
1009 * vpath.c (selective_vpath_search): Ditto.
1010 * dir.c (find_directory): Ditto.
1011 (local_stat): Ditto.
1012 (find_directory): Use ENULLLOOP() to wrap opendir().
1013 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
1015 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
1016 atomic_readdir() handling.
1018 2003-01-22 Paul D. Smith <psmith@gnu.org>
1020 * function.c (func_call): Fix Bug #1744. If we're inside a
1021 recursive invocation of $(call ...), mask any of the outer
1022 invocation's arguments that aren't used by this one, so that this
1023 invocation doesn't "inherit" them accidentally.
1025 2002-12-05 Paul D. Smith <psmith@gnu.org>
1027 * function.c (subst_expand): Valery Khamenia reported a
1028 pathological performance hit when doing substitutions on very
1029 large values with lots of words: turns out we were invoking
1030 strlen() a ridiculous number of times. Instead of having each
1031 call to sindex() call strlen() again, keep track of how much of
1032 the text we've seen and pass the length to sindex().
1034 2002-11-19 Paul D. Smith <psmith@gnu.org>
1036 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
1039 2002-11-16 Paul D. Smith <psmith@gnu.org>
1041 * NMakefile.template (OBJS): Add hash.c object file.
1042 * SMakefile.template (srcs): Ditto.
1043 * Makefile.ami (objs): Ditto.
1044 * build_w32.bat: Ditto.
1046 * Makefile.DOS.template: Remove extra dependencies.
1048 2002-10-25 Paul D. Smith <psmith@gnu.org>
1050 * expand.c (install_variable_buffer): New function. Install a new
1051 variable_buffer context and return the previous one.
1052 (restore_variable_buffer): New function. Free the current
1053 variable_buffer context and put a previously saved one back.
1054 * variable.h: Prototypes for {install,restore}_variable_buffer.
1055 * function.c (func_eval): Push a new variable_buffer context
1056 before we eval, then restore the old one when we're done.
1057 Fixes Bug #1517.
1059 * read.c (install_conditionals): New function. Install a new
1060 conditional context and return the previous one.
1061 (restore_conditionals): New function. Free the current
1062 conditional context and put a previously saved one back.
1063 (eval): Use the {install,restore}_conditionals for "include"
1064 handling.
1065 (eval_buffer): Use {install,restore}_conditionals to preserve the
1066 present conditional state before we evaluate the buffer.
1067 Fixes Bug #1516.
1069 * doc/make.texi (Quick Reference): Add references to $(eval ...)
1070 and $(value ...).
1071 (Recursion): Add a variable index entry for CURDIR.
1073 * README.cvs: Update to appropriate versions.
1074 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
1075 don't need to copy loadavg.c: automake is smart enough to create
1076 it for me. Still have a bug in automake related to ansi2knr tho.
1078 2002-10-14 Paul D. Smith <psmith@gnu.org>
1080 * remake.c (notice_finished_file): Only touch targets if they have
1081 at least one command (as per POSIX). Resolve Bug #1418.
1083 * *.c: Convert to using ANSI C-style function definitions.
1084 * Makefile.am: Enable the ansi2knr feature of automake.
1085 * configure.in: ditto.
1087 2002-10-13 Paul D. Smith <psmith@gnu.org>
1089 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
1090 for automatic variable values like $^, etc. In the case of very
1091 large lists of prerequisites this causes problems. Instead reuse
1092 a static buffer (resizeable) for each variable.
1094 * read.c (eval): Fix Bug #1391: allow "export" keyword in
1095 target-specific variable definitions. Check for it and set an
1096 "exported" flag.
1097 (record_target_var): Set the export field to v_export if the
1098 "exported" flag is set.
1099 * doc/make.texi (Target-specific): Document the ability to use
1100 "export".
1102 * doc/make.texi: Change the name of the section on automatic
1103 variables from "Automatic" to "Automatic Variables". Added text
1104 clarifying the scope of automatic variables.
1106 2002-10-04 Paul D. Smith <psmith@gnu.org>
1108 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
1109 as () braces.
1110 (record_files): Ditto.
1112 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
1113 the search for the '=' to only within the enclosing parens.
1115 2002-10-03 Paul D. Smith <psmith@gnu.org>
1117 Version 3.80 released.
1119 * dir.c: Change hash functions to use K&R function definition style.
1120 * function.c: Ditto.
1121 * read.c: Ditto.
1122 * variable.c: Ditto.
1124 Update to automake 1.7.
1126 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
1127 (pdf): Remove this target as automake now provides one.
1129 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
1131 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
1133 * makefile.com: Updates for GNU make 3.80.
1134 * makefile.vms: Ditto.
1136 2002-09-23 Paul D. Smith <psmith@gnu.org>
1138 * read.c (enum make_word_type): Remove w_comment.
1139 (get_next_mword): Don't treat comment characters as special; where
1140 this function is used we will never see a comment (it's stripped
1141 before we get here) and treating comments specially means that
1142 targets like "foo\#bar" aren't handled properly.
1144 2002-09-18 Paul D. Smith <psmith@gnu.org>
1146 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
1148 * read.c (eval): Expansion of arguments to export/unexport was
1149 ignoring all arguments after the first one. Change the algorithm
1150 to expand the whole line once, then parse the results.
1152 2002-09-17 Paul D. Smith <psmith@gnu.org>
1154 Fix Bug #940 (plus another bug I found while looking at this):
1156 * read.c (record_target_var): enter_file() will add a new entry if
1157 it's a double-colon target: we don't want to do that in this
1158 situation. Invoke lookup_file() and only enter_file() if it does
1159 not already exist. If the file we get back is a double-colon then
1160 add this variable to the "root" double-colon target.
1162 * variable.c (initialize_file_variables): If this file is a
1163 double-colon target but is not the "root" target, then initialize
1164 the root and make the root's variable list the parent of our
1165 variable list.
1167 2002-09-13 Paul D. Smith <psmith@gnu.org>
1169 * doc/make.texi (MAKE Variable): Add some indexing for "+".
1171 * hash.c (round_up_2): Get rid of a warning.
1173 2002-09-12 Paul D. Smith <psmith@gnu.org>
1175 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
1176 so it doesn't complain about getloadavg.c.
1178 * commands.c (set_file_variables): Make sure we always alloca() at
1179 least 1 character for the value of $? (for '\0').
1181 2002-09-11 Paul D. Smith <psmith@gnu.org>
1183 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
1184 macro to use RESULT instead of the incorrect _RESULT_.
1186 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
1187 and atomic_readdir(). We need to #include dirent.h to get this to
1188 work.
1189 * misc.c (atomic_readdir): Fix typos.
1191 2002-09-10 Paul D. Smith <psmith@gnu.org>
1193 * read.c (eval): Expand variable lists given to export and
1194 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
1195 (conditional_line): Ditto for "ifdef". Fixes bug #103.
1197 * doc/make.texi (Variables/Recursion): Document this.
1198 (Conditional Syntax): And here.
1200 2002-09-09 Paul D. Smith <psmith@gnu.org>
1202 * configure.in: Check for memmove().
1204 2002-09-07 Paul D. Smith <psmith@gnu.org>
1206 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
1207 Michael Sterrett <msterret@coat.com> reports that while it has
1208 SA_RESTART, it does not work properly.
1210 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
1211 that invokes stat() and loops to do it again if it returns EINTR.
1212 (atomic_readdir): Ditto, with readdir().
1214 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
1215 and readdir() to atomic_stat() and atomic_readdir().
1217 2002-09-04 Paul D. Smith <psmith@gnu.org>
1219 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
1220 reports that GNU make sometimes doesn't recognize that targets can
1221 be made, when directories can be created as prerequisites. He
1222 reports that changing the order of predicates in the DEP->changed
1223 flag test so that lookup_file() is always performed, solves this
1224 problem.
1226 2002-08-08 Paul D. Smith <psmith@gnu.org>
1228 * configure.in: Require a newer version of gettext.
1230 * misc.c (perror_with_name): Translate the format string (for
1231 right-to-left language support).
1232 (pfatal_with_name): Ditto.
1234 * main.c: Create a static array of strings to store the usage
1235 text. This is done to facilitate translations.
1236 (struct command_switch): Remove argdesc and description fields.
1237 (switches): Remove values for obsolete fields.
1238 (print_usage): Print each element of the usage array.
1240 * hash.c: Change function definitions to be K&R style.
1242 2002-08-02 Paul D. Smith <psmith@gnu.org>
1244 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
1245 this one because it's too hard to get right. We'll look at it for
1246 a future release.
1247 * main.c (main): Don't create the .TARGETS variable.
1248 * variable.c (handle_special_var): Don't handle .TARGETS.
1250 2002-08-01 Paul D. Smith <psmith@gnu.org>
1252 * main.c (switches): Add a new option, -B (--always-make). If
1253 specified, make will rebuild all targets that it encounters even
1254 if they don't appear to be out of date.
1255 (always_make_flag): New flag.
1256 * make.h: Extern always_make_flag.
1257 * remake.c (update_file_1): Check always_make_flag; if it's set we
1258 will always rebuild any target we can, even if none of its
1259 prerequisites are newer.
1260 * NEWS: Mention it.
1262 * doc/make.texi (Shell Function): Make it clear that make
1263 variables marked as "export" are not passed to instances of the
1264 shell function.
1266 Add new introspection variable .VARIABLES and .TARGETS.
1268 * variable.c (handle_special_var): New function. If the variable
1269 reference passed in is "special" (.VARIABLES or .TARGETS),
1270 calculate the new value if necessary. .VARIABLES is handled here:
1271 walk through the hash of defined variables and construct a value
1272 which is a list of the names. .TARGETS is handled by
1273 build_target_list().
1274 (lookup_variable): Invoke handle_special_var().
1275 * file.c (build_target_list): Walk through the hask of known files
1276 and construct a list of the names of all the ones marked as
1277 targets.
1278 * main.c (main): Initialize them to empty (and as simple variables).
1279 * doc/make.texi (Special Variables): Document them.
1280 * NEWS: Mention them.
1282 * variable.h (struct variable): Add a new flag "exportable" which
1283 is true if the variable name is valid for export.
1284 * variable.c (define_variable_in_set): Set "exportable" when a new
1285 variable is defined.
1286 (target_environment): Use the "exportable" flag instead of
1287 re-checking the name here... an efficiency improvement.
1289 2002-07-31 Paul D. Smith <psmith@gnu.org>
1291 * config.h-vms.template: Updates to build on VMS. Thanks to
1292 Brian_Benning@aksteel.com for helping verify the build.
1293 * makefile.com: Build the new hash.c file.
1294 * hash.h: Use strcpmi(), not stricmp(), in the
1295 HAVE_CASE_INSENSITIVE_FS case.
1297 2002-07-30 Paul D. Smith <psmith@gnu.org>
1299 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
1300 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
1301 Reported by <Brian_Benning@aksteel.com>.
1303 2002-07-10 Paul D. Smith <psmith@gnu.org>
1305 * variable.c (pop_variable_scope): Remove variable made unused by
1306 new hash infrastructure.
1307 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
1308 comparisons as well as name comparisons.
1309 * variable.h: Add a prototype for new hash_init_function_table().
1310 * file.c (lookup_file): Remove variables made unused by new hash
1311 infrastructure.
1312 * dir.c (directory_contents_hash_2): Missing return of hash value.
1313 (dir_contents_file_exists_p): Remove variables made unused by new
1314 hash infrastructure.
1317 Installed Greg McGary's integration of the hash functions from the
1318 GNU id-utils package:
1320 2002-07-10 Greg McGary <greg@mcgary.org>
1322 * scripts/functions/filter-out: Add literals to to the
1323 pattern space in order to add complexity, and trigger
1324 use of an internal hash table. Fix documentation strings.
1325 * scripts/targets/INTERMEDIATE: Reverse order of files
1326 passed to expected `rm' command.
1328 2002-07-10 Greg McGary <greg@mcgary.org>
1330 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
1331 * hash.c: New file, taken from id-utils.
1332 * hash.h: New file, taken from id-utils.
1334 * make.h (HASH, HASHI): Remove macros.

1342 (init_hash_files): New function decl.
1344 * ar.c (ar_name): Delay call to strlen until needed.
1345 * main.c (initialize_global_hash_tables): New function.
1346 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
1347 * misc.c (remove_comments): Pass char constants to find_char_unquote.
1348 * remake.c (notice_finished_file): Update last_mtime on `prev' chain.
1350 * dir.c (hash.h): New #include.
1351 (struct directory_contents) [next, files]: Remove members.
1352 [ctime]: Add member for VMS. [dirfiles]: Add hash-table member.

1354 directory_contents_hash_cmp): New functions.
1355 (directories_contents): Change type to `struct hash_table'.

1357 (directory_hash_1, directory_hash_2, directory_hash_cmp): New funcs.
1358 (directory): Change type to `struct hash_table'.
1359 (struct dirfile) [next]: Remove member.
1360 [length]: Add member. [impossible]: widen type to fill alignment gap.
1361 (dirfile_hash_1, dirfile_hash_2, dirfile_hash_cmp): New functions.
1362 (find_directory): Use new hash table package.
1363 (dir_contents_file_exists_p): Likewise.
1364 (file_impossible): Likewise.
1365 (file_impossible_p): Likewise.
1366 (print_dir_data_base): Likewise.
1367 (open_dirstream): Likewise.
1368 (read_dirstream): Likewise.
1369 (hash_init_directories): New function.
1371 * file.c (hash.h): New #include.
1372 (file_hash_1, file_hash_2, file_hash_cmp): New functions.
1373 (files): Change type to `struct hash_table'.
1374 (lookup_file): Use new hash table package.
1375 (enter_file): Likewise.
1376 (remove_intermediates): Likewise.
1377 (snap_deps): Likewise.
1378 (print_file_data_base): Likewise.
1380 * function.c
1381 (function_table_entry_hash_1, function_table_entry_hash_2,
1382 function_table_entry_hash_cmp): New functions.
1383 (lookup_function): Remove `table' argument.
1384 Use new hash table package.
1385 (struct a_word) [chain, length]: New members.
1386 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
1387 (struct a_pattern): New struct.
1388 (func_filter_filterout): Pass through patterns noting boundaries
1389 and '%', if present. Note a_word length. Use a hash table if
1390 arglists are large enough to justify cost.
1391 (function_table_init): Renamed from function_table.
1392 (function_table): Declare as `struct hash_table'.
1393 (FUNCTION_TABLE_ENTRIES): New constant.

1396 * read.c (hash.h): New #include.
1397 (read_makefile): Pass char constants to find_char_unquote.
1398 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
1399 (uniquize_deps): Use hash table to efficiently identify duplicates.
1400 (find_char_unquote): Accept two char-constant stop chars, rather
1401 than a string constant, avoiding zillions of calls to strchr.
1402 Tighten inner search loops to test only for desired delimiters.
1404 * variable.c (variable_hash_1, variable_hash_2,
1405 variable_hash_cmp): New functions.

1417 (target_environment): Likewise.
1418 (print_variable_set): Likewise.
1420 2002-07-10 Paul D. Smith <psmith@gnu.org>
1422 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
1423 prerequisite list. A real SysV make will expand the entire
1424 prerequisites list _twice_: we don't do that as it's a big
1425 backward-compatibility problem. We only replace those specific
1426 variables.
1428 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
1429 references left in the list of prerequisites. Check for .POSIX as
1430 we record targets, so we can disable non-POSIX behavior while
1431 reading makefiles as well as running them.
1432 (eval): Check the prerequisite list to see if we have anything
1433 that looks like a SysV prerequisite variable reference.
1435 2002-07-09 Paul D. Smith <psmith@gnu.org>
1437 * doc/make.texi (Prerequisite Types): Add a new section describing
1438 order-only prerequisites.
1440 * read.c (uniquize_deps): If we have the same file as both a
1441 normal and order-only prereq, get rid of the order-only prereq,
1442 since the normal one supersedes it.
1444 2002-07-08 Paul D. Smith <psmith@gnu.org>
1446 * AUTHORS: Added Greg McGary to the AUTHORS file.
1447 * NEWS: Blurbed order-only prerequisites.
1448 * file.c (print_file): Show order-only deps properly when printing
1449 the database.
1451 * maintMakefile: Add "update" targets for wget'ing the latest
1452 versions of various external files. Taken from Makefile.maint in
1453 autoconf, etc.
1455 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
1456 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
1458 2002-07-07 Paul D. Smith <psmith@gnu.org>
1460 * po/*.po: Remove. We'll use wget to retrieve them at release
1461 time.
1463 * variable.c (do_variable_definition) [W32]: On W32 using cmd
1464 rather than a shell you get an exception. Make sure we look up
1465 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
1467 * remake.c (notice_finished_file): Fix handling of -t flag.
1468 Patch provided by Henning Makholm <henning@makholm.net>.
1470 * implicit.c (pattern_search): Some systems apparently run short
1471 of stack space, and using alloca() in this function caused an
1472 overrun. I modified it to use xmalloc() on the two variables
1473 which seemed like they might get large. Fixes Bug #476.
1475 * main.c (print_version): Update copyright notice to conform with
1476 GNU standards.
1477 (print_usage): Update help output.
1479 * function.c (func_eval): Create a new make function, $(eval
1480 ...). Expand the arguments, put them into a buffer, then invoke
1481 eval_buffer() on the resulting string.
1482 (func_quote): Create a new function, $(quote VARNAME). Inserts
1483 the value of the variable VARNAME without expanding it any
1484 further.
1486 * read.c (struct ebuffer): Change the linebuffer structure to an
1487 "eval buffer", which can be either a file or a buffer.
1488 (eval_makefile): Move the code in the old read_makefile() which
1489 located a makefile into here: create a struct ebuffer with that
1490 information. Have it invoke the new function eval() with that
1491 ebuffer.
1492 (eval_buffer): Create a new function that creates a struct ebuffer
1493 that holds a string buffer instead of a file. Have it invoke
1494 eval() with that ebuffer.
1495 (eval): New function that contains the guts of the old
1496 read_makefile() function: this function parses makefiles. Obtains
1497 data to parse from the provided ebuffer. Some modifications to
1498 make the flow of the function cleaner and clearer. Still could
1499 use some work here...
1500 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
1501 contents of the define/endef variable from the ebuffer.
1502 (readstring): Read the next line from a string-style ebuffer.
1503 (readline): Read the next line from an ebuffer. If it's a string
1504 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
1505 from the file.
1507 * dep.h (eval_buffer): Prototype eval_buffer();
1509 * variable.c (do_variable_definition): Make sure that all
1510 non-target-specific variables are registered in the global set.
1511 If we're invoked from an $(eval ...) we might be inside a $(call
1512 ...) or other function which has pushed a variable scope; we still
1513 want to define our variables from evaluated makefile code in the
1514 global scope.
1516 2002-07-03 Greg McGary <greg@mcgary.org>
1518 * dep.h (struct dep) [ignore_mtime]: New member.
1519 [changed]: convert to a bitfield.
1520 * implicit.c (pattern_search): Zero ignore_mtime.
1521 * main.c (main, handle_non_switch_argument): Likewise.
1522 * rule.c (convert_suffix_rule): Likewise.
1523 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
1524 (read_makefile): Parse '|' in prerequisite list.
1525 (uniquize_deps): Consider ignore_mtime when comparing deps.
1526 * remake.c (update_file_1, check_dep): Don't force remake for
1527 dependencies that have d->ignore_mtime.
1528 * commands.c (FILE_LIST_SEPARATOR): New constant.
1529 (set_file_variables): Don't include a
1530 prerequisite in $+, $^ or $? if d->ignore_mtime.
1531 Define $|.
1533 2002-06-18 Paul D. Smith <psmith@gnu.org>
1535 * make.texinfo: Updates for next revision. New date/rev/etc.
1536 Recreate all Info menus. Change license on the manual to the GNU
1537 Free Documentation License. A number of typos.
1538 (Variables Simplify): Don't use "-" before it's defined.
1539 (Automatic Prerequisites): Rewrite the target example to work
1540 properly if the compile fails. Remove incorrect comments about
1541 how "set -e" behaves.
1542 (Text Functions): Move the "word", "wordlist", "words", and
1543 "firstword" functions here, from "File Name Functions".
1544 * make-stds.texi: Update from latest GNU version.
1545 * fdl.texi: (created) Import the latest GNU version.
1547 2002-06-06 Paul D. Smith <psmith@gnu.org>
1549 * variable.c (do_variable_definition): New function: extract the
1550 part of try_variable_definition() that actually sets the value
1551 into a separate function.
1552 (try_variable_definition): Call do_variable_definition() after
1553 parsing the variable definition string.
1554 (define_variable_in_set): Make the name argument const.
1556 * variable.h (enum variable_flavor): Make public.
1557 (do_variable_definition): Create prototype.
1559 * read.c (read_all_makefiles): Create a new built-in variable,
1560 MAKEFILE_LIST.
1561 (read_makefile): Add each makefile read in to this variable value.
1563 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
1565 * Makefile.DOS.template: Tweak according to changes in the
1566 distribution. Add back the dependencies of *.o files.
1568 * configh.dos.template: Synchronize with config.h.in.
1570 2002-05-09 Paul D. Smith <psmith@gnu.org>
1572 * file.c (file_timestamp_now): Use K&R function declaration.
1574 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
1575 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
1576 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
1577 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
1578 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
1579 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
1580 nlist.n_name is a pointer rather than an array.
1582 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
1583 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
1584 * configure.in: Use it instead of the old version.
1586 * main.c (main): Prefer setvbuf() to setlinebuf().
1588 2002-05-08 Paul D. Smith <psmith@gnu.org>
1590 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
1591 (loadavg_LDADD): Ditto.
1593 2002-04-29 Paul D. Smith <psmith@gnu.org>
1595 * expand.c (recursively_expand_for_file): Rename
1596 recursively_expand() to recursively_expand_for_file() and provide
1597 an extra argument, struct file. If the argument is provided, set
1598 the variable scope to that of the file before expanding.
1599 * variable.h (recursively_expand): Make this a macro that invokes
1600 recursively_expand_for_file() with a NULL file pointer.
1601 * variable.c (target_environment): Call the renamed function and
1602 provide the current file context.
1603 Fixes Debian bug #144306.
1605 2002-04-28 Paul D. Smith <psmith@gnu.org>
1607 Allow $(call ...) user-defined variables to be self-referencing
1608 without throwing an error. Allows implementation of transitive
1609 closures, among other possibly useful things.
1610 Requested by: Philip Guenther <guenther@sendmail.com>
1612 * variable.h (struct variable): Add a new field: exp_count, and
1613 new macros to hold its size and maximum value.
1614 (warn_undefined): Make this a macro.
1615 * variable.c (define_variable_in_set): Initialize it.
1616 * expand.c (recursively_expand): If we detect recursive expansion
1617 of a variable, check the exp_count field. If it's greater than 0
1618 allow the recursion and decrement the count.
1619 (warn_undefined): Remove this (now a macro in variable.h).
1620 * function.c (func_call): Before we expand the user-defined
1621 function, modify its exp_count field to contain the maximum
1622 number of recursive calls we'll allow. After the call, reset it
1623 to 0.
1625 2002-04-21 Paul D. Smith <psmith@gnu.org>
1627 Modified to use latest autoconf (2.53), automake (1.6.1), and
1628 gettext (0.11.1). We're using gettext's new "external" support,
1629 to avoid including libintl source with GNU make.
1631 * README.cvs: New file. Explain how to build GNU make from CVS.
1633 * configure.in: Modify checking for the system glob library.
1634 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
1635 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
1636 etc. will manage it correctly). Set an automake conditional
1637 USE_LOCAL_GLOB to decide whether to compile the glob library.
1639 * getloadavg.c (main): Include make.h in the "TEST" program to
1640 avoid warnings.
1642 * Makefile.am: Remove special rules for loadavg. Replace them
1643 with Automake capabilities for building extra programs.
1645 * signame.c: This file does nothing if the system provide
1646 strsignal(). If not, it implements strsignal(). If the system
1647 doesn't define sys_siglist, then we make our own; otherwise we use
1648 the system version.
1649 * signame.h: Removed.
1651 * main.c (main): No need to invoke signame_init(). Update copyright.
1653 * ABOUT-NLS: Removed.
1654 * gettext.c: Removed.
1655 * gettext.h: Get a simplified copy from the gettext package.
1656 * po/*: Created.
1657 * i18n/*.po: Moved to po/.
1658 * i18n/: Removed.
1660 * config/*: Created. Contains package configuration helper files.
1661 * config.guess, config.sub: Moved to config directory.
1663 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
1664 Rework to use new-style autoconf features. Use the "external"
1665 mode for gettext. Make the build.sh config file conditional on
1666 whether build.sh.in exists, to avoid autoconf errors.
1667 * acinclude.m4: Removed almost all macros as being obsolete.
1668 Rewrote remaining macros to use AC_DEFINE.
1669 * acconfig.h: Removed.
1671 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
1672 conditional to handle customs support. Remove special handling
1673 for i18n features.
1675 2002-04-20 Paul D. Smith <psmith@gnu.org>
1677 * function.c (func_call): Don't mark the argument variables $1,
1678 etc. as recursive. They've already been fully expanded so
1679 there's no need to do it again, and doing so strips escaped $'s.
1680 Reported by Sebastian Glita <glseba@yahoo.com>.
1682 * remake.c (notice_finished_file): Walk through double-colon
1683 entries via the prev field, not the next field!
1684 Reported by Greg McGary <greg@mcgary.org>.
1686 * main.c (main): If the user specifies -q and asks for a specific
1687 target which is a makefile, we got an assert. In that case it
1688 turns out we should continue normally instead.
1690 * i18n/de.po, i18n/fr.po: Installed an updated translation.
1692 * i18n/he.po: Installed a new translation.
1694 2002-01-07 Paul D. Smith <psmith@gnu.org>
1696 * i18n/es.po, i18n/ru.po: Installed an updated translation.
1698 2001-12-04 Paul D. Smith <psmith@gnu.org>
1700 * i18n/ja.po: Installed an updated translation.
1702 2001-09-06 Paul Eggert <eggert@twinsun.com>
1704 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
1705 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
1707 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
1708 are available.
1709 (main): Get rid of any avoidable limit on stack size.
1711 2001-09-04 Paul D. Smith <psmith@gnu.org>
1713 * i18n/da.po: Installed an updated translation.
1715 2001-08-03 Paul D. Smith <psmith@gnu.org>
1717 * i18n/fr.po: Installed an updated translation.
1718 Resolves Debian bug #106720.
1720 2001-06-13 Paul D. Smith <psmith@gnu.org>
1722 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
1723 translation.
1725 2001-06-11 Paul D. Smith <psmith@gnu.org>
1727 * i18n/ko.po: Installed a new translation.
1729 2001-05-06 Paul D. Smith <psmith@gnu.org>
1731 Modify the EINTR handling.
1733 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
1734 the way in which we manage the file descriptor/signal handler race
1735 trap to be more efficient.
1737 2001-05-06 Paul Eggert <eggert@twinsun.com>
1739 Restart almost all system calls that are interrupted, instead
1740 of worrying about EINTR. The lone exception is the read() for
1741 job tokens.
1743 * configure.in (HAVE_SA_RESTART): New macro.
1744 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
1745 * main.c (main): Use SA_RESTART instead of the old,
1746 nonstandard SA_INTERRUPT.
1748 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
1749 * main.c (bsd_signal): New function or macro,
1750 if the implementation doesn't supply it.
1751 (The bsd_signal function will be in POSIX 1003.1-200x.)
1752 (HANDLESIG): Remove.
1753 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
1755 * make.h (EINTR_SET): Remove.
1756 (SA_RESTART): New macro.
1758 * arscan.c (ar_member_touch): Don't worry about EINTR.
1759 * function.c (func_shell): Likewise.
1760 * job.c (reap_children, free_child, new_job): Likewise.
1761 * main.c (main): Likewise.
1762 * remake.c (touch_file, name_mtime): Likewise.
1764 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
1765 if fstat failed with errno!=EINTR, the error was ignored.
1767 * job.c (set_child_handler_action_flags): New function.
1768 (new_job): Use it to temporarily clear the SIGCHLD action flags
1769 while reading the token.
1771 2001-05-02 Paul D. Smith <psmith@gnu.org>
1773 * job.c (start_job_command): Don't add define/endef per-line flags
1774 to the top-level flags setting.
1776 2001-04-03 Paul D. Smith <psmith@gnu.org>
1778 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
1779 bit on error, so check for odd return values, not non-0 return
1780 values.
1781 (VMS_get_member_info): Calculate the timezone differences correctly.
1782 Reported by John Fowler <jfowler@nyx.net>.
1785 2001-03-14 Paul D. Smith <psmith@gnu.org>
1787 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
1788 value before invoking define_variable().
1789 Reported by John Fowler <jfowler@nyx.net>.
1791 2001-02-07 Paul D. Smith <psmith@gnu.org>
1793 * read.c (record_target_var): If we reset the variable due to a
1794 command-line variable setting overriding it, turn off the "append"
1795 flag.
1797 2001-01-17 Paul D. Smith <psmith@gnu.org>
1799 * variable.c (lookup_variable) [VMS]: When getting values from the
1800 environment, allocate enough space for the _value_ plus escapes,
1801 not enough space for the name plus escapes :-/.
1802 Reported by John Fowler <jfowler@nyx.net>.
1804 * remake.c (f_mtime): Removed the "***" prefix from the mod time
1805 warnings that make generates, so it doesn't look like an error.
1806 Reported by Karl Berry <karl@gnu.org>.
1809 Fix for PR/2020: Rework appended target-specific variables. I'm
1810 fairly confident this algorithm is finally correct.
1812 * expand.c (allocated_variable_append): Rewrite. Instead of
1813 expanding each appended variable then adding all the expanded
1814 strings together, we append all the unexpanded values going up
1815 through the variable set contexts, then expand the final result.
1816 This behaves just like non-target-specific appended variable
1817 values, while the old way didn't in various corner cases.
1818 (variable_append): New function: recursively append the unexpanded
1819 value of a variable, walking from the outermost variable scope to
1820 the innermost.
1821 * variable.c (lookup_variable): Remove the code that looked up the
1822 variable set list if the found variable was "append". We don't
1823 need this anymore.
1824 (lookup_variable_in_set): Make this non-static so we can use it
1825 elsewhere.
1826 (try_variable_definition): Use lookup_variable_in_set() rather
1827 than faking out current_variable_set_list by hand (cleanup).
1828 * variable.h: Add a prototype for the now non-static
1829 lookup_variable_in_set().
1831 2000-11-17 Paul D. Smith <psmith@gnu.org>
1833 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
1834 WINDOWS32 port to assume timestamps can be up to 3 seconds away
1835 before throwing a fit.
1837 2000-11-17 Paul D. Smith <psmith@gnu.org>
1839 * read.c (readline): CRLF calculations had a hole, if you hit the
1840 buffer grow scenario just right. Reworked the algorithm to avoid
1841 the need for len or lastlen at all. Problem description with
1842 sample code chages provided by Chris Faylor <cgf@redhat.com>.
1844 2000-10-24 Paul D. Smith <psmith@gnu.org>
1846 * gettext.c (SWAP): Declare this with the prototype, otherwise
1847 some systems don't work (non-32-bit? Reported for Cray T3E).
1848 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
1850 2000-10-05 Paul D. Smith <psmith@gnu.org>
1852 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
1853 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
1855 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
1857 2000-09-22 Paul D. Smith <psmith@gnu.org>
1859 * gettext.c: Don't #define _GETTEXT_H here; we only include some
1860 parts of the real gettext.h here, and we expect to really include
1861 the real gettext.h later. If we keep this #define, it's ignored.
1863 2000-09-21 Paul D. Smith <psmith@gnu.org>
1865 * main.c (log_working_directory): Rework the text to use complete
1866 sentences, to make life simpler for the translators.
1868 2000-08-29 Paul D. Smith <psmith@gnu.org>
1870 * file.c (remove_intermediates): Print a debug message before we
1871 remove intermediate files, so the user (if she uses -d) knows
1872 what's going on.
1874 2000-08-21 Paul D. Smith <psmith@gnu.org>
1876 * variable.c (try_variable_definition): Change how we handle
1877 target-specific append variable defns: instead of just setting the
1878 value, expand it as an append _but_ only within the current
1879 target's context. Otherwise we lose all but the last value if the
1880 variable is appended more than once within the current target
1881 context. Fixes PR/1831.
1883 2000-08-16 Paul D. Smith <psmith@gnu.org>
1885 * function.c (func_shell): Nul-terminate the buffer before
1886 printing an exec error message (just in case it's not!).
1887 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
1889 2000-07-25 Paul D. Smith <psmith@gnu.org>
1891 * job.c (construct_command_argv_internal): Add "~" to the list of
1892 sh_chars[] which disallow optimizing out the shell call.
1894 2000-07-23 Paul Eggert <eggert@twinsun.com>
1896 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
1897 supersedes --disable-nsec-timestamps.
1898 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
1899 * README: Remove --disable-nsec-timestamps.
1901 * filedef.h (struct file.low_resolution_time): New member.
1902 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
1903 * remake.c (update_file_1):
1904 Avoid spurious rebuilds due to low resolution time stamps,
1905 generalizing the earlier code that applied only to archive members.
1906 (f_mtime): Archive members always have low resolution time stamps.
1908 * configure.in: Remove --disable-nsec-timestamps, as this has
1909 been superseded by .LOW_RESOLUTION_TIME.
1911 2000-07-23 Paul Eggert <eggert@twinsun.com>
1913 * configure.in (enable_nsec_timestamps): Renamed from
1914 make_cv_nsec_timestamps, since enable/disable options
1915 shouldn't be cached.
1917 2000-07-23 Bruno Haible <haible@clisp.cons.org>
1918 and Paul Eggert <eggert@twinsun.com>
1920 * file.c (file_timestamp_now):
1921 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
1922 so that clock_gettime is not linked unless needed.
1924 * filedef.h (FILE_TIMESTAMP_HI_RES):
1925 Remove definition; "configure" now does this.
1927 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
1928 to before high resolution file timestamp check,
1929 since that check now uses uintmax_t.
1930 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
1931 high resolution file timestamps.
1932 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
1933 so that we don't link in clock_gettime unnecessarily.
1935 2000-07-17 Paul D. Smith <psmith@gnu.org>
1937 * i18n/ja.po: New version of the translation file.
1939 2000-07-07 Paul D. Smith <psmith@gnu.org>
1941 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
1942 the offset calculation.
1943 (name_mtime): Replace EINTR test with EINTR_SET macro.
1945 2000-07-07 Paul Eggert <eggert@twinsun.com>
1947 Fix for PR/1811:
1949 * remake.c (update_file_1):
1950 Avoid spurious rebuilds of archive members due to their
1951 timestamp resolution being only one second.
1952 (f_mtime): Avoid spurious warnings of timestamps in the future due to
1953 the clock's resolution being lower than file timestamps'.
1954 When warning about future timestamps, report only the discrepancy,
1955 not the absolute value of the timestamp and the current time.
1957 * file.c (file_timestamp_now): New arg RESOLUTION.
1958 * filedef.h (file_timestamp_now): Likewise.
1959 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
1961 2000-07-05 Paul D. Smith <psmith@gnu.org>
1963 * variable.c (lookup_variable) [VMS]: Remove vestigial references
1964 to listp. Fixes PR/1793.
1966 2000-06-26 Paul Eggert <eggert@twinsun.com>
1968 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
1970 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
1972 * remake.c (f_mtime): Remove unused var memtime.
1974 2000-06-25 Martin Buchholz <martin@xemacs.org>
1976 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
1977 Ran spell-check on make.texinfo.
1979 2000-06-23 Paul D. Smith <psmith@gnu.org>
1981 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
1982 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
1983 * make.h: Define these macros.
1985 * Version 3.79.1 released.
1987 * configure.in: Add a new option, --disable-nsec-timestamps, to
1988 avoid using sub-second timestamps on systems that support it. It
1989 can lead to problems, e.g. if your makefile relies on "cp -p".
1990 * README.template: Document the issue with "cp -p".
1992 * config.guess, config.sub: Updated.
