46 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
47 to normal upgrade logic from dep_hash_cmp to set_file_variables.
49 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
51 * dep.h (uniquize_deps): Remove.
53 * read.c (uniquize_deps): Merge into set_file_variables in
55 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
57 * commands.c (set_file_variables): Avoid modifying the dep
58 chain to achieve uniqueness. Fixes savannah bug 25780.
60 * implicit.c (pattern_search): Instead of re-setting all automatic
61 variables for each rule we try, just update $*.
63 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
65 * variable.h (undefine_variable_in_set): New function declaration.
66 (undefine_variable_global): New macro.
68 * variable.c (undefine_variable_in_set): New function implementation.
70 * read.c (vmodifiers): Add undefine_v modifier.

84 if we need to parse a rule that requires the second expansion.
86 2009-10-03 Paul Smith <psmith@gnu.org>
88 * make.h: Include <alloca.h> even on systems where __GNUC__ is
89 defined. Not sure why it was done the other way.
90 Requested by David Boyce <dsb@boyski.com>.
92 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
94 * dep.h (dep): Add the DONTCARE bitfield.
96 * filedef.h (file):Add the NO_DIAG bitfield.
98 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
99 not struct file (a file can be a dependency of many targets,
100 some don't care, some do).
102 * remake.c (update_goal_chain): Propagate DONTCARE from struct
103 dep to struct file before updating the goal and restore it
105 (update_file): Don't prune the dependency graph if this target
106 has failed but the diagnostics hasn't been issued.
107 (complain): Scan the file's dependency graph to find the file
108 that caused the failure.
109 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
110 whether to print diagnostics.
112 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
114 2009-09-28 Paul Smith <psmith@gnu.org>
116 * doc/make.texi (Pattern Intro): Move the match algorithm
117 discussion into the "Pattern Match" node.
118 (Pattern Match): Expand on the pattern rule matching algorithm.
120 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
122 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
123 much of the command line on a single pass.
125 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
127 * varible.c (create_pattern_var): Insert variables into the
128 PATTERN_VARS list in the shortest patterns first order.
130 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
131 used to sort the rules.
132 (stemlen_compare): Compare two tryrule elements.
133 (pattern_search): Sort the rules so that they are in the shortest
136 * main.c (.FEATURES): Add a keyword to indicate the new behavior.

143 * NEWS: Add a note about the new behavior.
145 2009-09-27 Paul Smith <psmith@gnu.org>
147 * doc/make.texi (Double-Colon): Mention that pattern rules with
148 double-colons have a different meaning. Savannah bug #27497.
150 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
152 * configh.dos.template: Remove unconditional definition of
153 SYS_SIGLIST_DECLARED.
154 Include <sys/version.h> because ports of GCC 4.3.0 and later no
155 longer include it, so macros like __DJGPP_MINOR__ are no longer
156 defined automatically.
158 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
159 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
160 instead of using the hardcoded ones.
161 (SUBDIRS): doc subdir added.
162 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
163 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
164 create html formated docs. texi2html may not be ported to DOS.
165 (make.info, make.dvi, make.ps, make.html): Make targets depend on
167 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
168 -I switch to look in ./ instead of ./doc.
169 (html): Target depend on html-recursive instead of make_1.html.
170 (make_1.html): Removed.
171 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
172 (all-recursive): Allow for more than one subdir in the build
174 (mostlyclean-recursive, clean-recursive, distclean-recursive)
175 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
176 (tags-recursive): Allow for more than one subdir in the build
178 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
179 targets. Enter into doc/ to produce the targets.
180 (all-am): $(INFO_DEPS) replaced by info.
182 2009-09-26 Paul Smith <psmith@gnu.org>
184 * read.c (record_files): Use free_ns() to free struct nameseq.
187 * rule.c (freerule): Use free_dep_chain().
189 * read.c (record_files): Free FILENAMES chain for implicit rules.
190 (eval): Static pattern targets go into the string cache.
192 * function.c (string_glob): Free NAME in the nameseq chain.
194 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
196 * implicit.c (pattern_search): Terminate early if we haven't
197 found any rules to try (performance improvement).
199 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
201 * implicit.c (pattern_search): Merge three parallel arrays,
202 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
203 of struct TRYRULE. In the old version the latter two arrays
204 had insufficient length.
206 2009-09-24 Paul Smith <psmith@gnu.org>
208 * implicit.c (pattern_search): Add back support for order-only
209 prerequisites for secondary expansion implicit rules, that were
210 accidentally dropped. If we find a "|", enable order-only mode
211 and set IGNORE_MTIME on all deps that are seen afterward.
212 (pattern_search): Fix memory leaks: for intermediate files where
213 we've already set the file variable and pattern variable sets, be
214 sure to either save or free them as appropriate.
216 2009-09-23 Paul Smith <psmith@gnu.org>
218 Rework the way secondary expansion is stored, for efficiency.
219 This changes secondary expansion so that ONLY WHEN we know we have
220 a possibility of needing secondary expansion, do we defer the
221 secondary expansion. This means more parsing the deps but we use
222 a lot less memory (due to the strcache). Also, this fixes
225 * read.c (eval): Don't parse the dep string here anymore.
226 (record_files): Take the dep argument as an unparsed string. If
227 secondary expansion is enabled AND the prereq string has a '$' in
228 it, then set NEED_2ND_EXPANSION and keep the entire string.
229 Otherwise, parse the dep string here to construct the dep list
230 with the names in the strcache.
232 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
233 duplicate the name string (others are in the strcache).
235 * implicit.c: Remove struct idep and free_idep_chain(): unused.
236 (struct patdeps): New structure to store prereq information.
237 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
238 which prerequisites need expansion, and expand only those.
240 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
241 and enter_prereqs(). split_prereqs() takes a fully-expanded string
242 and splits it into a DEP list, handling order-only prereqs.
243 (enter_prereqs): This function enters a list of DEPs into the file
244 database. If there's a stem defined, expand any pattern chars.
245 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
246 set. Use the above functions.
247 (snap_deps): Only perform second expansion on prereqs that need it,
248 as defined by the NEED_2ND_EXPANSION flag.
249 (print_prereqs): New function to print the prereqs
250 (print_file): Call print_prereqs() rather than print inline.
252 * hash.h (STRING_COMPARE): Take advantage of strcache() by
254 (STRING_N_COMPARE): Ditto.
255 (ISTRING_COMPARE): Ditto.
257 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
258 (parse_file_seq): Return void*
259 * read.c (parse_file_seq): Return void*.
260 (eval): Invoke macroized version of parse_file_seq()
261 * default.c (set_default_suffixes): Ditto.
262 * file.c (split_prereqs): Ditto.
263 * function.c (string_glob): Ditto.
264 * main.c (main): Ditto.
265 * rule.c (install_pattern_rule): Ditto.
267 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
269 2009-09-16 Paul Smith <psmith@gnu.org>
271 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
273 * dep.h: Create alloc_dep() / free_dep() macros.
275 * implicit.c (pattern_search): Take advantage of the new
276 parse_file_seq() to add the directory prefix to each prereq.
278 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
279 all. Avoid reversing chains. Support adding prefixes.
280 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
281 cached/non-cached results.
282 (eval): Remove multi_glob() & invoke new parse_file_seq().
283 * rule.c (install_pattern_rule): Ditto.
284 * main.c (main): Ditto.
285 * implicit.c (pattern_search): Ditto.
286 * function.c (string_glob): Ditto.
287 * file.c (parse_prereqs): Ditto.
288 * default.c (set_default_suffixes): Ditto.
290 * variable.c (parse_variable_definition): Don't run off the end of
291 the string if it ends in whitespace (found with valgrind).
293 * commands.c (set_file_variables): Keep space for all targets in
294 $? if -B is given (found with valgrind).
296 2009-09-15 Paul Smith <psmith@gnu.org>
298 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
299 (xcalloc): Add new function.
300 * make.h: New declarations.
302 * ar.c (ar_glob_match): New calling method for concat().
303 * main.c (main): Ditto.
304 (decode_env_switches): Ditto.
305 * read.c (eval_makefile): Ditto.
306 (tilde_expand): Ditto.
307 (parse_file_seq): Ditto.
308 * variable.c (target_environment): Ditto.
309 (sync_Path_environment): Ditto.
311 * ar.c (ar_glob_match): Use xcalloc().
312 * dir.c (file_impossible): Ditto.
313 * file.c (enter_file): Ditto.
314 * job.c (new_job): Ditto.
315 * read.c (parse_file_seq): Ditto.
316 * vmsfunctions.c (opendir): Ditto.
318 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
320 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
321 inside the loop that looks up environment for PATH.
323 2009-08-31 Eli Zaretskii <eliz@gnu.org>
325 * function.c (windows32_openpipe): Update envp after calling
326 sync_Path_environment.
328 2009-08-02 Paul Smith <psmith@gnu.org>
330 * remake.c (notice_finished_file): Ensure file->cmds is not null
331 before looping through them. Fixes Savannah bug #21824.
333 * doc/make.texi (Wildcard Examples): Clarify when objects is
334 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
335 (Include): Clarify the behavior of -include.
336 Fixes Savannah bug #18963.
338 2009-08-01 Paul Smith <psmith@gnu.org>
340 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
341 etc. come on the command line. Fixes Savannah bug #27093.
343 * expand.c (expand_argument): If the argument is large enough use
344 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
346 * variable.c (do_variable_definition): Avoid using alloca() to
347 hold values, which can be large. Fixes Savannah bug #23960.
349 * job.c (new_job): Use memmove() instead of strcpy() since both
350 pointers are in the same memory block. Fixes Savannah bug #27148.
351 Patch by Petr Machata.
353 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
355 * job.c (construct_command_argv_internal): Add "ulimit" and
356 "unset" to the sh_cmds for Unixy shells.
358 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
360 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
361 that set make_cv_sys_gnu_glob, so they are also correctly set
362 when the cache has been populated before.
364 2009-07-04 Eli Zaretskii <eliz@gnu.org>
366 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
367 exist, as realpath(3) does where it's supported.
369 2006-07-04 Eli Zaretskii <eliz@gnu.org>
371 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
372 (abspath): Support systems that define HAVE_DOS_PATHS (have
373 drive letters in their file names). Use IS_PATHSEP instead of a
374 literal '/' comparison. Fixes Savannah bug #26886.
376 2009-06-14 Paul Smith <psmith@gnu.org>
378 * remake.c (update_file_1): Remember the original file we marked
379 as updating, so we can clear that flag again. If we find a target
380 via vpath, FILE might change.
381 (check_dep): Ditto. Fixes Savannah bug #13529.
382 Patch by Reid Madsen <reid.madsen@tek.com>.
384 2009-06-13 Paul Smith <psmith@gnu.org>
386 * doc/make.texi (MAKEFILES Variable): Be explicit that files
387 included by MAKEFILES cannot give default goals.
388 * read.c (eval): If set_default is not set, pass the no-default-goal
389 value when we read included makefiles. Fixes Savannah bug #13401.
391 * ar.c (ar_name): Ensure that targets with empty parens aren't
392 considered archive member references: archive members must have a
393 non-empty "member" string. Fixes Savannah bug #18435.
395 * function.c (string_glob): Rely on multi_glob() to determine
396 whether files exist or not. Remove call to file_exists_p() which
397 is not always correct. Fixes Savannah bug #21231.
398 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
399 then only files that really exist will be returned.
400 * dep.h: Add new argument to multi_glob().
401 * rule.c (install_pattern_rule): Ditto.
402 * read.c (eval): Ditto.
403 * main.c (main): Ditto.
404 * implicit.c (pattern_search): Ditto.
405 * file.c (parse_prereqs): Ditto.
406 * default.c (set_default_suffixes): Ditto.
408 2009-06-09 Paul Smith <psmith@gnu.org>
410 * commands.c (set_file_variables): If always_make_flag is set,
411 always add the prereq to $?. Fixes Savannah bug #17825.
413 * remake.c (update_file_1): When rebuilding deps of FILE, also try
414 to rebuild the deps of all the also_make targets for that file.
415 Fixes Savannah bug #19108.
417 * implicit.c (pattern_search): Undo test for is_target, added by
418 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
419 Rule Search Algorithm". Fixes Savannah bug #17752.
421 * main.c (clean_jobserver): Clear the jobserver_fds options and
422 set job_slots to the default when we clean up.
423 (define_makeflags): Return the new MAKEFLAGS value.
424 (main): Reset MAKEFLAGS in the environment when we re-exec.
425 Fixes Savannah bug #18124.
427 2009-06-08 Paul Smith <psmith@gnu.org>
429 * read.c (eval): Collapse continuations post-semicolon on target-
430 specific variables. Fixes Savannah bug #17521.
432 2009-06-07 Paul Smith <psmith@gnu.org>
434 * job.c (reap_children): For older systems without waitpid() (are
435 there any of these left?) run wait(2) inside EINTRLOOP to handle
436 EINTR errors. Fixes Savannah bug #16401.
438 * (various): Debug message cleanup. Fixes Savannah bug #16469.
440 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
442 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
443 not the end, to catch second expansion $(eval ...) defining new
444 target/prereq relationships during snap_deps.
445 Fixes Savannah bug #24622.
447 * read.c (record_files): The second-expansion "f->updating" hack
448 was not completely correct: if assumed that the target with
449 commands always had prerequisites; if one didn't then the ordering
450 was messed up. Fixed for now to use f->updating to decide whether
451 to preserve the last element in the deps list... but this whole
452 area of constructing and reversing the deps list is too confusing
453 and needs to be reworked. Fixes Savannah bug #21198.
455 2009-06-06 Paul Smith <psmith@gnu.org>
457 * hash.c (hash_insert): Remove useless test for NULL.
458 Fixes Savannah bug #21823.
460 * make.h: Move SET_STACK_SIZE determination to make.h.
461 * main.c (main): New global variable, STACK_LIMIT, holds the
462 original stack limit when make was started.
463 * job.c (start_job_command): Reset the stack limit, if we changed it.
464 Fixes Savannah bug #22010.
466 * remake.c (check_dep): Only set the target's state to not-started
467 if it's not already running. Found this while testing -j10 builds
468 of glibc: various targets were being rebuilt multiple times.
469 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
472 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
473 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
476 2009-06-04 Paul Smith <psmith@gnu.org>
478 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
480 * maintMakefile: Modify access of config and gnulib Savannah
481 modules to use GIT instead of CVS.
483 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
484 Fixes Savannah bug #24655.
486 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
487 this can happen during some invocations of $(eval ...) for example.
488 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
490 2009-06-02 Paul Smith <psmith@gnu.org>
492 * configure.in: Check for fileno()
493 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
494 for the makefile file so invocations of $(shell ...) don't inherit it.
495 Fixes Savannah bug #24277.
497 2009-06-01 Paul Smith <psmith@gnu.org>
499 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
500 expansion was handled incorrectly. Rework the default goal
501 handling to save the variable only. Remove default_goal_file and
503 * read.c (eval): Check default_goal_var, not default_goal_name.
504 * read.c (record_target_var): Don't check default_goal_file here.
506 2009-05-31 Paul Smith <psmith@gnu.org>
508 * main.c (main): Expand the .DEFAULT_GOAL variable before using
509 it, and if the multi_glob() returns nothing (say it expanded to
510 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
512 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
513 $(and ..) to the reference. Fixes Savannah bug #25694.
515 * make.1: Be clear that some recipes will be executed even with -n.
516 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
518 * doc/make.texi (Override Directive): Make more clear how
519 overrides and appends interact.
520 Elucidates part of Savannah bug #26207.
522 * read.c (record_target_var): Don't reset the origin on
523 target-specific variables; try_variable_definition() will handle
524 this correctly. Fixes Savannah bug #26207.
526 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
527 Fixes Savannah bug #25712.
529 * implicit.c (pattern_search): Keep a pointer to the beginning of
530 the filename and save that instead of the constructed pointer.
531 Fixes Savannah bug #26593.
532 Patch by Mark Seaborn <mrs@mythic-beasts.com>
534 2009-05-30 Paul Smith <psmith@gnu.org>
536 * doc/make.texi (Multi-Line): Add a description of the new abilities
537 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
538 "command sequence" vs. "recipe" syntax.
539 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
540 after a define, to create variables with those flavors.
542 2009-05-25 Paul Smith <psmith@gnu.org>
544 Reworked the parser for variable assignments to allow multiple
545 modifiers, and in any order. Also allows variable and
546 prerequisites to be modifier names ('export', 'private', etc.)
548 * NEWS: Add notes about user-visible changes.
550 * read.c (struct vmodifiers): Remember what modifiers were seen.

571 Loop over an array of extensions, instead of duplicating the same
572 code inline. Use SearchPath followed by CreateFile, instead of
573 the obsolete OpenFile. Fixes Savannah bug #17277.
574 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
575 to `find_file'. Fixes Savannah bug #25662.

706 2007-10-12 Eli Zaretskii <eliz@gnu.org>
708 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
709 a more complex value than a simple shell: if it's not a default

765 * read.c (eval): Remove the cmd_prefix characters from the command
766 scripts here, so they're not stored in the commands array at all,
767 rather than waiting and stripping them out during command construction.
768 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
770 2007-08-15 Paul Smith <psmith@gnu.org>

836 Dave Korn <dave.korn@artimi.com>
838 2007-05-08 Paul Smith <psmith@gnu.org>
840 Fix Savannah bug #19656:
842 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
844 * make.h: Change all case-insensitive string compares to use
845 strcasecmp() (from POSIX). If we don't have that but do have one
846 of the others, define strcasecmp to be one of those instead. If
847 we don't have any, declare a prototype for our own version.
849 * misc.c (strcasecmp): Use this if we can't find any native
850 case-insensitive string comparison function.
851 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
852 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
854 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
855 strcasecmp() instead of stricmp().
856 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
857 instead of strcmpi().
858 * acinclude.m4: Remove the strcasecmp() check from here.
860 2007-03-21 Paul Smith <psmith@gnu.org>
862 * configure.in: Don't turn on case-insensitive file system support
863 if --disable-... is given. Fixes Savannah bug #19348.
865 2007-03-19 Paul Smith <psmith@gnu.org>
867 * ALL: Use the strcache for all file name strings, or other
868 strings which we will never free. The goal is to save memory by
869 avoiding duplicate copies of strings. However, at the moment this
870 doesn't save much memory in most situations: due to secondary
871 expansion we actually save prerequisite lists twice (once before
872 the secondary expansion, and then again after it's been parsed
873 into individual file names in the dep list). We will resolve this
874 in a future change, by doing the parsing up-front for targets
875 where secondary expansion is not set.
877 Moving things into the strcache also allows us to use const
878 pointers in many more places.
880 2007-01-03 Paul Smith <psmith@gnu.org>
882 * make.h (ENULLLOOP): Reset errno after each failed invocation of
883 the function, not just the first. Fixes Savannah bug #18680.
885 2006-11-18 Paul Smith <psmith@gnu.org>
887 * strcache.c (strcache_add_len): Don't allocate a new buffer
888 unless the string is not already nil-terminated. Technically this
889 is a violation of the standard, since we may be passed an array
890 that is not long enough to test one past. However, in make this
891 is never true since we only use nil-terminated strings or
894 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
896 * main.c: New global cmd_prefix, defaults to '\t'.
897 * job.c (construct_command_argv_internal): Use cmd_prefix instead
901 (dir_contents_file_exists_p): Check for an error return from
902 readdir(), just in case.
904 * commands.c: Constified.
905 * default.c: Constified.
906 * expand.c: Constified.
907 * function.c: Partial constification.
908 * variable.c: Partial constification.
909 * vmsify.c: Constification. Hard to test this but I hope I didn't

923 2006-10-21 Paul Smith <psmith@gnu.org>
926 * arscan.c: Constified.
928 2006-09-30 Paul Smith <psmith@gnu.org>
930 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
931 point to lastword since the example was updated.
932 Fixes Savannah bug #16304.

936 variable references or function calls.
937 Fixes Savannah bug #16577.
938 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
939 Fixes Savannah bug #17701.

1098 allow multiple concurrent runs.
1099 Patch from Joseph Myers <joseph@codesourcery.com>
1101 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1103 * dep.h (struct dep): Add the stem field.
1104 * misc.c (alloc_dep, free_dep): New functions.
1105 (copy_dep_chain): Copy stem.
1106 (free_dep_chain): Use free_dep.
1107 * read.c (record_files): Store stem in the dependency line.
1108 * file.c (expand_deps): Use stem stored in the dependency line. Use
1109 free_dep_chain instead of free_ns_chain.
1110 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1111 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1112 * main.c (main, handle_non_switch_argument): Ditto.
1113 * remake.c (check_dep): Ditto.
1114 * rule.c (convert_suffix_rule, freerule): Ditto.
1116 2006-03-14 Paul D. Smith <psmith@gnu.org>
1118 * expand.c (variable_append): Instead of appending everything then
1119 expanding the result, we expand (or not, if it's simple) each part
1121 (allocated_variable_append): Don't expand the final result.
1122 Fixes Savannah bug #15913.
1124 2006-03-09 Paul Smith <psmith@gnu.org>
1126 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1127 listed non-existent files as changed. Turns out there's a bug in
1128 the Linux kernel builds which means that this change causes
1129 everything to rebuild every time. We will re-introduce this fix
1130 in the next release, to give them time to fix their build system.
1131 Fixes Savannah bug #16002.
1132 Introduces Savannah bug #16051.
1134 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1135 we *don't* find UNIX "/".
1136 Reported by David Ergo <david.ergo@alterface.com>
1138 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1140 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1141 locator function find_and_set_default_shell if SHELL came from the
1144 2006-02-20 Paul D. Smith <psmith@gnu.org>
1146 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1147 to be null; don't core in that case.
1149 2006-02-19 Paul D. Smith <psmith@gnu.org>
1151 * commands.c (set_file_variables): Realloc, not malloc, the static
1152 string values to avoid memory leaks.
1154 * expand.c (recursively_expand_for_file): Only set reading_file to
1155 an initialized value.
1157 * implicit.c (pattern_search): We need to make a copy of the stem
1158 if we get it from an intermediate dep, since those get freed.
1160 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1162 (enter_file) [VMS]: Ditto.
1163 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1165 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1167 * job.c (construct_command_argv_internal): Fix last change.
1169 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1170 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1171 the calls to _beginthreadex.
1173 * expand.c (recursively_expand_for_file): Initialize `save' to
1174 prevent compiler warnings.
1176 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1178 * job.c (construct_command_argv_internal): Don't create a temporary
1179 script/batch file if we are under -n. Call _setmode to switch the
1180 script file stream to text mode.
1182 2006-02-17 Paul D. Smith <psmith@gnu.org>
1184 * variable.c (merge_variable_set_lists): Don't try to merge the
1185 global_setlist. Not only is this useless, but it can lead to
1186 circularities in the linked list, if global_setlist->next in one
1187 list gets set to point to another list which also ends in
1189 Fixes Savannah bug #15757.
1191 2006-02-15 Paul D. Smith <psmith@gnu.org>
1193 Fix for Savannah bug #106.
1195 * expand.c (expanding_var): Keep track of which variable we're
1196 expanding. If no variable is being expanded, it's the same as
1198 * make.h (expanding_var): Declare it.
1199 * expand.c (recursively_expand_for_file): Set expanding_var to the
1200 current variable we're expanding, unless there's no file info in
1201 it (could happen if it comes from the command line or a default
1202 variable). Restore it before we exit.
1203 * expand.c (variable_expand_string): Use the expanding_var file
1204 info instead of the reading_file info.
1205 * function.c (check_numeric): Ditto.
1207 (func_wordlist): Ditto.
1208 (func_error): Ditto.
1209 (expand_builtin_function): Ditto.
1210 (handle_function): Ditto.
1212 2006-02-14 Paul D. Smith <psmith@gnu.org>
1214 * read.c (eval): Even if the included filenames expands to the
1215 empty string we still need to free the allocated buffer.
1217 * implicit.c (pattern_search): If we allocated a variable set for
1218 an impossible file, free it.
1219 * variable.c (free_variable_set): New function.
1220 * variable.h: Declare it.
1222 * read.c (read_all_makefiles): Makefile names are kept in the
1223 strcache, so there's never any need to alloc/free them.
1226 * main.c (main): Add "archives" to the .FEATURES variable if
1227 archive support is enabled.
1228 * doc/make.texi (Special Variables): Document it.
1230 2006-02-13 Paul D. Smith <psmith@gnu.org>
1232 * implicit.c (pattern_search): Add checking for DOS pathnames to
1233 the pattern rule target LASTSLASH manipulation.

1238 * (ALL FILES): Updated copyright and license notices.
1240 2006-02-10 Paul D. Smith <psmith@gnu.org>
1242 A new internal capability: the string cache is a read-only cache
1243 of strings, with a hash table interface for fast lookup. Nothing
1244 in the cache will ever be freed, so there's no need for reference
1245 counting, etc. This is the beginning of a full solution for
1246 Savannah bug #15182, but for now we only store makefile names here.
1248 * strcache.c: New file. Implement a read-only string cache.
1249 * make.h: Add prototypes for new functions.
1250 * main.c (initialize_global_hash_tables): Initialize the string cache.
1251 (print_data_base): Print string cache stats.
1252 * read.c (eval_makefile): Use the string cache to store makefile
1253 names. Rewrite the string allocation to be sure we free everything.
1255 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1257 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1258 directory time stamp didn't change, except on FAT filesystems.
1259 Suggested by J. David Bryan <jdbryan@acm.org>.
1261 2006-02-09 Paul D. Smith <psmith@gnu.org>
1263 * function.c (func_or): Implement a short-circuiting OR function.
1264 (func_and): Implement a short-circuiting AND function.
1265 (function_table_init): Update the table with the new functions.
1266 * doc/make.texi (Conditional Functions): Changed the "if" section
1267 to one on general conditional functions. Added documentation for
1268 $(and ...) and $(or ...) functions.
1269 * NEWS: Note new $(and ...) and $(or ...) functions.
1271 2006-02-08 Boris Kolpackov <boris@kolpackov.net>

1274 * job.c (new_job): Cache dontcare flag.
1275 * job.c (reap_children): Use cached dontcare flag instead of the
1276 one in struct file. Fixes Savannah bug #15641.
1278 2006-02-06 Paul D. Smith <psmith@gnu.org>
1280 * vpath.c (selective_vpath_search): If the file we find has a
1281 timestamp from -o or -W, use that instead of the real time.
1282 * remake.c (f_mtime): If the mtime is a special token from -o or
1283 -W, don't overwrite it with the real mtime.
1284 Fixes Savannah bug #15341.
1286 Updates from Markus Mauhart <qwe123@chello.at>:
1288 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1289 (process_signal, process_last_err, process_exit_code): Manage
1290 invalid handle values.
1291 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1292 manage invalid handles; remove them.

1294 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1295 * README.cvs: Updates for building from CVS.
1297 2006-02-05 Paul D. Smith <psmith@gnu.org>
1299 * file.c (enter_file): Keep track of the last double_colon entry,
1300 to avoid walking the list every time we want to add a new one.
1301 Fixes Savannah bug #15533.
1302 * filedef.h (struct file): Add a new LAST pointer.
1304 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1305 the comparison. For 64-bits systems the result of the subtraction
1306 might not fit into an int. Use comparison instead.
1307 Fixes Savannah bug #15534.
1309 * doc/make.texi: Update the chapter on writing commands to reflect
1310 the changes made in 3.81 for backslash/newline and SHELL handling.
1312 2006-02-01 Paul D. Smith <psmith@gnu.org>
1314 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1315 variable st is not used when it's not initialized.

1330 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1332 * remake.c (update_goal_chain): Set g->changed instead of
1333 incrementing it, as it is only 8-bit wide, and could overflow if
1334 many commands got started in update_file.
1336 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1338 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1339 MAXIMUM_WAIT_OBJECTS.
1340 (process_wait_for_any_private): Change dimension of handles[]
1341 array to MAXIMUM_WAIT_OBJECTS.
1342 (process_used_slots): New function.
1343 (process_register): Don't register more processes than the
1344 available number of slots.
1345 (process_easy): Don't start new processes if all slots are used up.
1347 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1348 are already more children than sub_proc.c can handle, behave as if
1349 the load were too high.
1350 (start_job_command): Fix a typo in error message when process_easy
1353 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1355 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1356 the shell is not sh.exe.
1358 * job.c (create_batch_file): Renamed from create_batch_filename;
1359 all callers changed. Don't close the temporary file; return its
1360 file descriptor instead. New arg FD allows to return the file
1362 (construct_command_argv_internal): Use _fdopen instead of fopen to
1363 open the batch file.
1365 2006-01-04 Paul D. Smith <psmith@gnu.org>
1367 * readme.vms: Updates for case-insensitive VMS file systems from
1368 Hartmut Becker <Hartmut.Becker@hp.com>.

1388 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1389 disable warnings for MSC.
1390 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1392 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1394 * doc/make.texi (Execution): Add a footnote about changes in
1395 handling of backslash-newline sequences. Mention the differences
1396 on MS-DOS and MS-Windows.
1398 * NEWS: More details about building the MinGW port and a pointer
1399 to README.W32. Fix the section name that describes the new
1400 backward-incompatible processing of backslash-newline sequences.
1401 The special processing of SHELL set to "cmd" is only relevant to
1402 MS-Windows, not MS-DOS.
1404 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1406 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1407 to DWORD, to avoid compiler warnings.
1408 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1409 use %ld in format, to avoid compiler warnings.
1411 * doc/make.texi (Special Targets): Fix a typo.
1412 (Appending): Fix cross-reference to Setting.
1413 (Special Variables, Secondary Expansion, File Name Functions)

1423 * read.c (record_target_var): Initialize variable's export field
1424 with v_default instead of leaving it "initialized" by whatever
1425 garbage happened to be on the heap.

1429 * make.1: Fix some display errors and document all existing options.
1430 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1432 2005-12-11 Paul D. Smith <psmith@gnu.org>
1434 * implicit.c (pattern_search): If 2nd expansion is not set for
1435 this implicit rule, replace the pattern with the stem directly,
1436 and don't re-expand the variable list. Along with the other
1437 .SECONDEXPANSION changes below, fixes bug #13781.
1439 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1441 * implicit.c (pattern_search): Mark other files that this rule
1442 builds as targets so that they are not treated as intermediates
1443 by the pattern rule search algorithm. Fixes bug #13022.
1445 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1447 * remake.c (notice_finished_file): Propagate the change of
1448 modification time to all the double-colon entries only if

1467 * read.c (record_files): Don't set deps flags if there are no deps.
1468 * maintMakefile: We only need to build the templates when we are
1469 creating a distribution, so don't do it for "all".
1471 2005-10-24 Paul D. Smith <psmith@gnu.org>
1473 Make secondary expansion optional: its enabled by declaring the
1474 special target .SECONDEXPANSION.
1476 * NEWS: Update information on second expansion capabilities.
1477 * doc/make.texi (Secondary Expansion): Document the
1478 .SECONDEXPANSION special target and its behavior.

1480 prerequisite list was found in a static pattern rule.
1481 (free_dep_chain): Declare a prototype.
1482 * file.c (parse_prereqs): New function: break out some complexity
1484 (expand_deps): If we aren't doing second expansion, replace % with
1485 the stem for static pattern rules. Call the new function.
1486 * filedef.h (parse_prereqs): Declare a prototype.
1487 * implicit.c (pattern_search): Initialize the new staticpattern
1489 * main.c (second_expansion): Declare a global variable to remember
1490 if the special target has been seen. Initialize the new
1491 staticpattern field for prerequisites.
1492 * make.h: Extern for second_expansion.
1493 * misc.c (free_dep_chain): New function: frees a struct dep list.
1494 * read.c (read_all_makefiles): Initialize the staticpattern field.
1495 (eval_makefile): Ditto.
1496 (record_files): Check for the .SECONDEXPANSION target and set
1497 second_expansion global if it's found.
1498 Use the new free_dep_chain() instead of doing it by hand.
1499 Set the staticpattern field for prereqs of static pattern targets.
1501 2005-10-16 Paul D. Smith <psmith@gnu.org>
1503 * main.c (main): Set CURDIR to be a file variable instead of a
1504 default, so that values of CURDIR inherited from the environment
1505 won't override the make value.
1507 2005-09-26 Paul D. Smith <psmith@gnu.org>
1509 * job.c (construct_command_argv_internal): If the line is empty
1510 remember to free the temporary argv strings.
1513 2005-09-16 Paul D. Smith <psmith@gnu.org>
1515 * job.c (start_job_command): The noerror flag is a boolean (single
1516 bit); set it appropriately.
1517 Reported by Mark Eichin <eichin@metacarta.com>
1519 2005-08-29 Paul D. Smith <psmith@gnu.org>
1521 * function.c (func_error): On Windows, output from $(info ...)
1522 seems to come in the wrong order. Try to force it with fflush().
1524 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1526 * read.c (record_files): Move code that sets stem for static
1527 pattern rules out of the if (!two_colon) condition so it is
1528 also executed for two-colon rules. Fixes Savannah bug #13881.
1530 2005-08-08 Paul D. Smith <psmith@gnu.org>
1532 * make.h: Don't test that __STDC__ is non-0. Some compilers
1533 (Windows for example) set it to 0 to denote "ISO C + extensions".
1536 2005-08-07 Paul D. Smith <psmith@gnu.org>
1538 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1539 conditional (slightly different version of a fix from Eli).
1541 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1542 If make is running in parallel without -k and two jobs die in a
1543 row, but not too close to each other, then make will quit without
1544 waiting for the rest of the jobs to die.
1546 * main.c (die): Don't reset err before calling reap_children() the
1547 second time: we still want it to be in the error condition.
1548 * job.c (reap_children): Use a static variable, rather than err,
1549 to control whether or not the error message should be printed.
1551 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1553 * w32/subproc/sub_proc.c: Include signal.h.
1554 (process_pipe_io, process_file_io): Pass a pointer to a local
1555 DWORD variable to GetExitCodeProcess. If the exit code is
1556 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1558 * job.c [WINDOWS32]: Include windows.h.
1559 (main_thread) [WINDOWS32]: New global variable.
1560 (reap_children) [WINDOWS32]: Get the handle for the main thread
1561 and store it in main_thread.
1563 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1564 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1565 doing anything else. When we are done, close the main thread
1566 handle and exit with status 130.
1568 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1570 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1573 * main.c (find_and_set_default_shell): If found a DOSish shell,
1574 set sh_found and the value of default_shell, and report the
1575 findings in debug mode.
1577 * job.c (construct_command_argv_internal): Check unixy_shell, not
1578 no_default_sh_exe, to decide whether to use Unixy or DOSish
1581 * README.W32: Update with info about the MinGW build.
1583 * build_w32.bat: Support MinGW.
1585 * w32/subproc/build.bat: Likewise.
1587 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1588 printing DWORD args.
1590 * function.c (windows32_openpipe): Fix format strings for printing
1593 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1595 (start_job_command): Fix format string for printing the result of
1597 (start_job_command) [WINDOWS32]: Do not define.
1598 (exec_command): Fix format string for printing HANDLE args.
1600 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1601 to avoid compiler warnings.
1602 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1603 (Note: some of these fixes were submitted independently by J. Grant)
1605 2005-07-30 J. Grant <jg@jguk.org>
1607 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1608 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1609 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1611 2005-07-15 Paul Smith <psmith@gnu.org>
1613 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1614 we don't have a POSIX shell, then revert to the old
1615 backslash-newline behavior (where they are stripped).
1618 2005-07-08 Paul D. Smith <psmith@gnu.org>
1620 * config.h.W32.template: Reorder to match the standard config.h,
1621 for easier comparisons.
1622 From J. Grant <jg@jguk.org>
1624 * maintMakefile: Remove .dep_segment before overwriting it, in
1625 case it's not writable or noclobber is set.
1626 * expand.c (variable_expand_string): Cast result of pointer
1627 arithmetic to avoid a warning.
1628 * main.c (switches): Add full-fledged final initializer.
1630 2005-07-06 Paul D. Smith <psmith@gnu.org>
1632 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1633 * signame.c (strsignal): If we found _sys_siglist[] or
1634 __sys_siglist[] use those instead of sys_siglist[].
1635 From Albert Chin <china@thewrittenword.com>
1637 2005-07-04 Paul D. Smith <psmith@gnu.org>
1639 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1640 globfree(); set up to use the GNU versions.
1641 From Martin Zinser <zinser@zinser.no-ip.info>
1643 2005-07-03 Paul D. Smith <psmith@gnu.org>
1645 From J. Grant <jg@jguk.org>:
1647 * README.W32.template: Update the Windows and tested MSVC versions.
1648 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1649 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1650 * build_w32.bat: Ditto.
1651 * w32/subproc/build.bat: Ditto.
1653 2005-06-28 Paul D. Smith <psmith@gnu.org>
1655 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1656 declaration was checked but not present.
1658 2005-06-27 Paul D. Smith <psmith@gnu.org>
1660 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1661 to unsigned long. Fixes Savannah bug #13550.
1663 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1664 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1665 Fixes Savannah bug #13551.
1667 2005-06-26 Paul D. Smith <psmith@gnu.org>
1669 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1670 it if ANSI_STRING is not set.
1672 2005-06-25 Paul D. Smith <psmith@gnu.org>
1674 * read.c (eval): If no filenames are passed to any of the
1675 "include" variants, don't print an error.
1676 * doc/make.texi (Include): Document this.
1677 Fixes Savannah bug #1761.
1679 * job.c (construct_command_argv_internal): Sanitize handling of
1680 backslash/newline pairs according to POSIX: that is, keep the
1681 backslash-newline in the command script, but remove a following
1682 TAB character, if present. In the fast path, make sure that the
1683 behavior matches what the shell would do both inside and outside
1684 of quotes. In the slow path, quote the backslash and put a
1685 literal newline in the string.
1686 Fixes Savannah bug #1332.
1687 * doc/make.texi (Execution): Document the new behavior and give
1689 * NEWS: Make a note of the new behavior.
1691 * make.h [WINDOWS32]: #include <direct.h>.
1692 Fixes Savannah bug #13478.
1694 * remake.c (name_mtime): If the stat() of a file fails and the -L
1695 option was given and the file is a symlink, take the best mtime of
1696 the symlink we can get as the mtime of the file and don't fail.
1697 Fixes Savannah bug #13280.
1699 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1700 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1701 inside a variable reference. Make this function static as it's
1703 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1704 parsing an unexpanded line looking for semicolons.
1705 Fixes Savannah bug #1454.
1706 * misc.c (remove_comments): Move this to read.c and make it static
1707 as it's only used there. Call find_char_unquote() with new arg.
1708 * make.h: Remove prototypes for find_char_unquote() and
1709 remove_comments() since they're static now.
1711 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1712 its export flag and obtain its value. When we need to re-exec,
1713 increment the value and add it into the environment.
1714 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1715 * NEWS: Mention MAKE_RESTARTS.
1716 * main.c (always_make_set): New variable. Change the -B option to
1717 set this one instead.
1718 (main): When checking makefiles, only set always_make_flag if
1719 always_make_set is set AND the restarts flag is 0. When building
1720 normal targets, set it IFF always_make_set is set.
1721 (main): Avoid infinite recursion with -W, too: only set what-if
1722 files to NEW before we check makefiles if we've never restarted
1723 before. If we have restarted, set what-if files to NEW _after_ we
1725 Fixes Savannah bug #7566:
1727 2005-06-17 Paul D. Smith <psmith@gnu.org>
1729 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1730 in the prerequisites list.
1732 2005-06-12 Paul D. Smith <psmith@gnu.org>
1734 Fix Savannah bug # 1328.
1736 * configure.in: Check for atexit().
1737 * misc.c (close_stdout): Test stdout to see if writes to it have
1738 failed. If so, be sure to exit with a non-0 error code. Based on
1739 code found in gnulib.
1740 * make.h: Prototype.
1741 * main.c (main): Install close_stdout() with atexit().
1743 2005-06-10 Paul D. Smith <psmith@gnu.org>
1745 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1747 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1748 headers; make vmsWaitForChildren() static; extern vmsify().
1749 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1750 Don't create child_execute_job() here (it's in vmsjobs.c).
1751 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1753 2005-06-09 Paul D. Smith <psmith@gnu.org>
1755 * variable.c (push_new_variable_scope): File variables point
1756 directly to the global_setlist variable. So, inserting a new
1757 scope in front of that has no effect on those variables: they
1758 don't go through current_variable_set_list. If we're pushing a
1759 scope and the current scope is global, push it "the other way" so
1760 that the new setlist is in the global_setlist variable, and
1761 next points to a new setlist with the global variable set.
1762 (pop_variable_scope): Properly undo a push with the new
1764 Fixes Savannah bug #11913.
1766 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1768 * job.c (reap_children): Don't die of the command failed but
1769 the dontcare flag is set. Fixes Savannah bug #13216.
1771 * implicit.c (pattern_search): When creating a target from
1772 an implicit rule match, lookup pattern target and set precious
1773 flag in a newly created target. Fixes Savannah bug #13218.
1775 2005-05-13 Paul D. Smith <psmith@gnu.org>
1777 Implement "if... else if... endif" syntax.
1779 * read.c (eval): Push all checks for conditional words ("ifeq",
1780 "else", etc.) down into the conditional_line() function.
1781 (conditional_line): Rework to allow "else if..." clause. New
1782 return value -2 for lines which are not conditionals. The
1783 ignoring flag can now also be 2, which means "already parsed a
1784 true branch". If that value is seen no other branch of this
1785 conditional can be considered true. In the else parsing if there
1786 is extra text after the else, invoke conditional_line()
1787 recursively to see if it's another conditional. If not, it's an
1788 error. If so, raise the conditional value to this level instead
1789 of creating a new conditional nesting level. Special check for
1790 "else" and "endif", which aren't allowed on the "else" line.
1791 * doc/make.texi (Conditional Syntax): Document the new syntax.
1793 2005-05-09 Paul D. Smith <psmith@gnu.org>
1795 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1796 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1797 recurses to the w32 directory, even on non-Windows systems. Use
1798 the method suggested in the automake manual.
1799 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1800 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1802 2005-05-07 Paul D. Smith <psmith@gnu.org>
1804 * main.c (die): If we're dying with a fatal error (not that a
1805 command has failed), write back any leftover tokens before we go.
1807 * job.c (set_child_handler_action_flags): If there are jobs
1808 waiting for the load to go down, set an alarm to go off in 1
1809 second. This allows us to wake up from a potentially long-lasting
1810 read() and start a new job if the load has gone down. Turn it off
1812 (job_noop): Dummy signal handler function.
1813 (new_job): Invoke it with the new semantics.
1815 * docs/make.texi: Document secondary expansion. Various cleanups
1818 2005-05-03 Paul D. Smith <psmith@gnu.org>
1820 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1821 the targets which are to ultimately be made are called "goals";
1822 see the GNU make manual. Also, MAKECMDGOALS, etc.
1824 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1825 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1826 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1828 2005-05-02 Paul D. Smith <psmith@gnu.org>
1830 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1831 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1832 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1833 functions to vmsjobs.c. #include it into jobs.c.
1835 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1836 jobserver tokens. I found that this happens when an exported
1837 recursive variable contains a $(shell ...) function reference: in
1838 this situation we could "forget" to write back a token.
1840 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1841 we have. It's not reliable to depend on the number of children in
1842 our linked list so keep a separate count.
1843 (new_job): Check jobserver_tokens rather than children &&
1844 waiting_jobs. Increment jobserver_tokens when we get one.
1845 (free_child): If jobserver_tokens is 0, internal error. If it's
1846 >1, write a token back to the jobserver pipe (we don't write a
1847 token for the "free" job). Decrement jobserver_tokens.
1849 * main.c: Add variable master_job_slots.
1850 (main): Set it to hold the number of jobs requested if we're the
1851 master process, when using the jobserver.
1852 (die): Sanity checks: first test jobserver_tokens to make sure
1853 this process isn't holding any tokens we didn't write back.
1854 Second, if master_job_slots is set count the tokens left in the
1855 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1857 2005-04-24 Paul D. Smith <psmith@gnu.org>
1859 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1860 with -l# can lose jobserver tokens, because waiting jobs are not
1861 consulted properly when checking for the "free" token.
1863 * job.c (free_child): Count waiting_jobs as having tokens.
1864 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1865 handle jobs waiting for the load to drop.
1867 2005-04-23 Paul D. Smith <psmith@gnu.org>
1869 * main.c (main): Be careful to not core if a variable setting in
1870 the environment doesn't contain an '='. This is illegal but can
1871 happen in broken setups.
1872 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1874 2005-04-12 Paul D. Smith <psmith@gnu.org>
1876 The second expansion feature causes significant slowdown. Timing
1877 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1878 read the makefile before the feature, to 11+s to do the same
1879 operations after the feature. Additionally, memory usage
1880 increased drastically. To fix this I added some intelligence that
1881 avoids the overhead of the second expansion unless it's required.
1883 * dep.h: Add a new boolean field, need_2nd_expansion.
1885 * read.c (eval): When creating the struct dep for the target,
1886 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1887 (record_files): If there's a "%" in a static pattern rule, it gets
1888 converted to "$*" so set need_2nd_expansion to 1.
1890 * file.c (expand_deps): Rework to be more efficient. Only perform
1891 initialize_file_variables(), set_file_variables(), and
1892 variable_expand_for_file() if the need_2nd_expansion is set.
1894 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1895 (pattern_search): Ditto.
1896 * main.c (handle_non_switch_argument): Ditto.
1898 * read.c (read_all_makefiles): Ditto.
1899 (eval_makefile): Ditto.
1901 2005-04-07 Paul D. Smith <psmith@gnu.org>
1903 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1904 * variable.c (sync_Path_environment): Ditto.
1905 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1907 * main.c (main): Define the .FEATURES variable.
1908 * NEWS: Announce .FEATURES.
1909 * doc/make.texi (Special Variables): Document .FEATURES.
1911 * remake.c (check_dep): If a file is .PHONY, update it even if
1912 it's marked intermediate. Fixes Savannah bug #12331.
1914 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1916 * file.c (expand_deps): Factor out the second expansion and
1917 prerequisite line parsing logic from snap_deps().
1919 * file.c (snap_deps): Use expand_deps(). Expand and parse
1920 prerequisites of the .SUFFIXES special target first. Fixes
1921 Savannah bug #12320.
1923 2005-03-13 Paul D. Smith <psmith@gnu.org>
1925 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1928 2005-03-11 Paul D. Smith <psmith@gnu.org>
1930 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1931 available, not undefined (from Earnie Boyd).
1933 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1935 * implicit.c (pattern_search): Mark an intermediate target as
1936 precious if it happened to be a prerequisite of some (other)
1937 target. Fixes Savannah bug #12267.
1939 2005-03-09 Paul D. Smith <psmith@gnu.org>
1941 * read.c (eval_makefile): Add alloca(0).
1942 (eval_buffer): Ditto.
1944 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1946 * main.c (main): Use o_file instead of o_default when defining
1947 the .DEFAULT_TARGET special variable.
1948 * read.c (eval): Use define_variable_global() instead of
1949 define_variable() when setting new value for the .DEFAULT_TARGET
1950 special variable. Fixes Savannah bug #12266.
1952 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1954 * imlicit.c (pattern_search): Mark files for which an implicit
1955 rule has been found as targets. Fixes Savannah bug #12202.
1957 2005-03-04 Paul D. Smith <psmith@gnu.org>
1960 * doc/make.texi (Automatic Variables): Document $|.
1962 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1964 * read.c (record_files): Instead of substituting % with
1965 actual stem value in dependency list replace it with $*.
1966 This fixes stem triple expansion bug.
1968 * implicit.c (pattern_search): Copy stem to a separate
1969 buffer and make it a properly terminated string. Assign
1970 this buffer instead of STEM (which is not terminated) to
1971 f->stem. Instead of substituting % with actual stem value
1972 in dependency list replace it with $*. This fixes stem
1973 triple expansion bug.
1975 2005-03-01 Paul D. Smith <psmith@gnu.org>
1977 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1978 on Windows, as it takes a handle not a pid. Just exit.
1979 Fix from patch #3679, provided by Alessandro Vesely.
1981 * configure.in: Update check for sys_siglist[] from autoconf manual.
1982 * signame.c (strsignal): Update to use the new autoconf macro.
1984 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1986 * read.c (record_files): Add a check for the list of prerequisites
1987 of a static pattern rule being empty. Fixes Savannah bug #12180.
1989 2005-02-28 Paul D. Smith <psmith@gnu.org>
1991 * doc/make.texi (Text Functions): Update docs to allow the end
1992 ordinal for $(wordlist ...) to be 0.
1993 * function.c (func_wordlist): Fail if the start ordinal for
1994 $(wordlist ...) is <1. Matches documentation.
1995 Resolves Savannah support request #103195.
1997 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1998 previously we were stopping when !-q, exactly the opposite. This
1999 has been wrong since version 1.34, in 1994!
2000 (update_file): If we got an error don't break out to run more
2001 double-colon rules: just return immediately.
2002 Fixes Savannah bug #7144.
2004 2005-02-27 Paul D. Smith <psmith@gnu.org>
2006 * misc.c (end_of_token): Make argument const.
2007 * make.h: Update prototype.
2009 * function.c (abspath, func_realpath, func_abspath): Use
2010 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2011 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2012 * read.c (record_files): Ditto.
2013 * variable.c (do_variable_definition): Ditto.
2015 * function.c (func_error): Create a new function $(info ...) that
2016 simply prints the message to stdout with no extras.
2017 (function_table_init): Add new function to the table.
2018 * NEWS: Add $(info ...) reference.
2019 * doc/make.texi (Make Control Functions): Document it.
2021 New feature: if the system supports symbolic links, and the user
2022 provides the -L/--check-symlink-time flag, then use the latest
2023 mtime between the symlink(s) and the target file.
2025 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2026 readlink(). If both are available, define MAKE_SYMLINKS.
2027 * main.c: New variable: check_symlink_flag.
2028 (usage): Add a line for -L/--check-symlink-times to the help string.
2029 (switches): Add -L/--check-symlink-times command line argument.
2030 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2031 print a warning and disable it again.
2032 * make.h: Declare check_symlink_flag.
2033 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2034 if the file is a symlink then check each link in the chain and
2035 choose the NEWEST mtime we find as the mtime for the file. The
2036 newest mtime might be the file itself!
2037 * NEWS: Add information about this new feature.
2038 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2040 Avoid core dumps described in Savannah bug # 12124:
2042 * file.c: New variable snapped_deps remember whether we've run
2044 (snap_deps): Set it.
2045 * filedef.h: Extern it.
2046 * read.c (record_files): Check snapped_deps; if it's set then
2047 we're trying to eval a new target/prerequisite relationship from
2048 within a command script, which we don't support. Fatal.
2050 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2052 Implementation of the .DEFAULT_TARGET special variable.
2054 * read.c (eval): If necessary, update default_target_name when
2056 * read.c (record_files): Update default_target_file if
2057 default_target_name has changed.
2058 * main.c (default_target_name): Define.
2059 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2060 default_target_name is set use default_target_file as a root
2062 * filedef.h (default_target_name): Declare.
2063 * dep.h (free_dep_chain):
2064 * misc.c (free_dep_chain): Change to operate on struct nameseq
2065 and change name to free_ns_chain.
2066 * file.c (snap_deps): Update to use free_ns_chain.
2068 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2070 Implementation of the second expansion in explicit rules,
2071 static pattern rules and implicit rules.
2073 * read.c (eval): Refrain from chopping up rule's dependencies.
2074 Store them in a struct dep as a single dependency line. Remove
2075 the code that implements SySV-style automatic variables.
2077 * read.c (record_files): Adjust the code that handles static
2078 pattern rules to expand all percents instead of only the first
2079 one. Reverse the order in which dependencies are stored so that
2080 when the second expansion reverses them again they appear in
2081 the makefile order (with some exceptions, see comments in
2082 the code). Remove the code that implements SySV-style automatic
2085 * file.c (snap_deps): Implement the second expansion and chopping
2086 of dependency lines for explicit rules.
2088 * implicit.c (struct idep): Define an auxiliary data type to hold
2089 implicit rule's dependencies after stem substitution and
2092 * implicit.c (free_idep_chain): Implement.
2094 * implicit.c (get_next_word): Implement helper function for
2095 parsing implicit rule's dependency lines into words taking
2096 into account variable expansion requests. Used in the stem
2099 * implicit.c (pattern_search): Implement the second expansion
2100 for implicit rules. Also fixes bug #12091.
2102 * commands.h (set_file_variables): Declare.
2103 * commands.c (set_file_variables): Remove static specifier.
2105 * dep.h (free_dep_chain): Declare.
2106 * misc.c (free_dep_chain): Implement.
2108 * variable.h (variable_expand_for_file): Declare.
2109 * expand.c (variable_expand_for_file): Remove static specifier.
2111 * make.h (strip_whitespace): Declare.
2112 * function.c (strip_whitespace): Remove static specifier.
2114 2005-02-26 Paul D. Smith <psmith@gnu.org>
2116 * main.c (main): Check for ferror() when reading makefiles from stdin.
2117 Apparently some shells in Windows don't close pipes properly and
2120 2005-02-24 Jonathan Grant <jg@jguk.org>
2122 * configure.in: Add MinGW configuration options, and extra w32 code
2124 * Makefile.am: Add MinGW configuration options, and extra w32 code
2126 * main.c: Determine correct program string (after last \ without .exe).
2127 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2129 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2130 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2131 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2132 environment support.
2134 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2136 * function.c (func_shell): When initializing error_prefix, check
2137 that reading file name is not null. This fixes long-standing
2138 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2140 2005-02-09 Paul D. Smith <psmith@gnu.org>
2142 * maintMakefile: Update the CVS download URL to simplify them.
2143 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2144 downloading the .texi files from Savannah now.
2146 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2148 * main.c (handle_non_switch_argument): Only add variables to
2149 command_variables if they're not already there: duplicate settings
2150 waste space and can be confusing to read.
2152 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2153 this header is never included by non-WINDOWS32 code, and it
2154 requires <config.h> to define which isn't always included first.
2156 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2157 testing MINGW32 versions.
2159 * main.c (log_working_directory): flush stdout to be sure the WD
2160 change is printed before any stderr messages show up.
2162 2005-02-01 Paul D. Smith <psmith@gnu.org>
2164 * maintMakefile (po_repo): Update the GNU translation site URL.
2166 2004-12-01 Paul D. Smith <psmith@gnu.org>
2168 * main.c (main): Change char* env_shell to struct variable shell_var.
2169 * variable.c (target_environment): Use new shell_var.
2171 2004-11-30 Paul D. Smith <psmith@gnu.org>
2173 * configure.in: The old way we avoided creating build.sh from
2174 build.sh.in before build.sh.in exists doesn't work anymore; we
2175 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2176 the help!). This also keeps automake from complaining.
2177 * Makefile.am (README): Add a dummy target so automake won't
2178 complain that this file doesn't exist when we checkout from CVS.
2179 * maintMakefile (.dep_segment): Rewrite this rule since newer
2180 versions of automake don't provide DEP_FILES.
2182 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2184 Implementation of `realpath' and `abspath' built-in functions.
2186 * configure.in: Check for realpath.
2187 * function.c (abspath): Return an absolute file name that does
2188 not contain any `.' or `..' components, nor repeated `/'.
2189 * function.c (func_abspath): For each name call abspath.
2190 * function.c (func_realpath): For each name call realpath
2191 from libc or delegate to abspath if realpath is not available.
2192 * doc/make.texi (Functions for File Names): Document new functions.
2193 * doc/make.texi (Quick Reference): Ditto.
2195 2004-11-28 Paul D. Smith <psmith@gnu.org>
2197 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2198 arguments. Fixes bug #10252.
2200 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2202 * main.c (main): Set SHELL to v_noexport by default. Remember the
2203 original environment setting of SHELL in the env_shell variable.
2204 * main.h: Export new env_shell variable.
2205 * variable.c (target_environment): If we find a v_noexport
2206 variable for SHELL, add a SHELL variable with the env_shell value.
2207 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2208 * doc/make.texi (Variables/Recursion): Ditto.
2210 2004-11-28 Paul D. Smith <psmith@gnu.org>
2212 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2213 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2214 Patch by Alessandro Vesely.
2216 2004-11-12 Paul D. Smith <psmith@gnu.org>
2218 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2219 the command line if it's inside a string.
2220 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2222 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2224 * function.c (func_lastword): New function: return last word
2225 from the list of words.
2226 * doc/make.texi: Document $(lastword ). Fix broken links in
2227 Quick Reference section.
2229 2004-10-06 Paul D. Smith <psmith@gnu.org>
2231 Apply patch from Alessandro Vesely, provided with bug # 9748.
2232 Fix use of tmpnam() to work with Borland C.
2234 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2235 construction of a temporary filename, and call new function
2236 create_batch_filename().
2237 (create_batch_filename) [WINDOWS32]: New function to create a
2240 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2242 * read.c (record_target_var): Expand simple pattern-specific
2244 * variable.c (initialize_file_variables): Do not expand simple
2245 pattern-specific variable.
2247 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2249 * remake.c (update_file_1): When rebuilding makefiles inherit
2250 dontcare flag from a target that triggered update.
2252 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2254 * variable.c (initialize_file_variables): Mark pattern-specific
2255 variable as a per-target and copy export status.
2257 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2259 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2261 * implicit.c (pattern_search): When considering an implicit rule's
2262 prerequisite check that it is actually a target rather then
2263 just an entry in the file hashtable.
2265 2004-09-21 Paul D. Smith <psmith@gnu.org>
2267 * read.c (readstring): Fix some logic errors in backslash handling.
2268 (eval): Remove some unnecessary processing in buffer handling.
2269 (record_target_var): Assert that parse_variable_definition() succeeded.
2270 Reported by: Markus Mauhart <qwe123@chello.at>.
2272 * misc.c: Removed the sindex() function. All instances of this
2273 function were trivially replaceable by the standard strstr()
2274 function, and that function will always have better (or certainly
2275 no worse) performance than the very simple-minded algorithm
2276 sindex() used. This can matter with complex makefiles.
2277 * make.h: Remove the prototype for sindex().
2278 * function.c (subst_expand): Convert sindex() call to strstr().
2279 This means we no longer need to track the TLEN value so remove that.
2280 (func_findstring): Convert sindex() to strstr().
2281 * commands.c (chop_commands): Convert sindex() calls to strstr().
2282 Suggested by: Markus Mauhart <qwe123@chello.at>.
2284 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2285 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2286 If SHELL is set to CMD.EXE then assume it's batch-mode and
2287 non-unixy. I wrote the code differently from the patch, though,
2288 to make it safer. This also resolves bug #9174.
2290 2004-09-20 Paul D. Smith <psmith@gnu.org>
2292 * expand.c (variable_expand_string): Modify to invoke
2293 patsubst_expand() instead of subst_expand(); the latter didn't
2294 handle suffix patterns correctly.
2295 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2296 was used only from variable_expand_string() and is no longer used
2298 (func_subst): Ditto, on call to subst_expand().
2299 (patsubst_expand): Require the percent pointers to point to the
2300 character after the %, not to the % itself.
2301 * read.c (record_files): New call criteria for patsubst_expand().
2302 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2303 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2305 2004-09-19 Paul D. Smith <psmith@gnu.org>
2307 * function.c (subst_expand): Fix a check in by_word: look for a
2308 previous blank if we're beyond the beginning of the string, not
2309 the beginning of the word.
2310 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2312 2004-05-16 Paul D. Smith <psmith@gnu.org>
2314 * remake.c (update_goal_chain): Change the argument specifying
2315 whether we're rebuilding makefiles to be a global variable,
2316 REBUILDING_MAKEFILES.
2317 (complain): Extract the code that complains about no rules to make
2318 a target into a separate function.
2319 (update_file_1): If we tried to rebuild a file during the makefile
2320 rebuild phase and it was dontcare, then no message was printed.
2321 If we then try to build the same file during the normal build,
2322 print a message this time.
2323 (remake_file): Don't complain about un-remake-able files when
2324 we're rebuilding makefiles.
2326 2004-05-11 Paul D. Smith <psmith@gnu.org>
2328 * job.c (construct_command_argv_internal): OS/2 patches from
2329 Andreas Buening <andreas.buening@nexgo.de>.
2331 2004-05-10 Paul D. Smith <psmith@gnu.org>
2333 * remake.c (update_file): Don't walk the double-colon chain unless
2334 this is a double-colon rule. Fix suggested by Boris Kolpackov
2335 <boris@kolpackov.net>.
2337 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2338 * readme.vms: New section describing OpenVMS support and issues.
2339 * default.c (default_variables): Add support for IA64.
2340 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2341 without some privilege aborts make with the error
2342 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2343 pressing Ctrl+Y and the input device is no terminal. The change
2344 catches this error and just continues.
2346 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2348 2004-04-25 Paul D. Smith <psmith@gnu.org>
2350 * commands.c (set_file_variables): Set $< properly in the face of
2351 order-only prerequisites.
2352 Patch from Boris Kolpackov <boris@kolpackov.net>
2354 2004-04-21 Bob Byrnes <byrnes@curl.com>
2356 * main.c (main): Notice failures to remake makefiles.
2358 2004-03-28 Paul D. Smith <psmith@gnu.org>
2360 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2362 * job.c: No default shell for RISC OS.
2363 (load_too_high): Hard-code the return to 1.
2364 (construct_command_argv_internal): No sh_chars or sh_cmds.
2365 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2367 2004-03-20 Paul D. Smith <psmith@gnu.org>
2369 * variable.c (do_variable_definition): Don't append from the
2370 global set if a previous non-appending target-specific variable
2371 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2374 * expand.c (reference_variable): Don't give up on variables with
2375 no value that have the target-specific append flag set: they might
2376 have a value after all. Reported by Oliver Schmidt
2377 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2378 <nikulin@dx1cmd.inp.nsk.su>.
2380 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2381 refer to absolute pathnames in directories that don't exist: some
2382 portion of the makefile could create those directories before we
2383 match the pattern. Fixes bugs #775 and #108.
2385 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2387 * main.c (main): Free makefile_mtimes if we have any.
2388 * README.W32.template: Update documentation for the current status
2389 of the MS-Windows port.
2390 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2391 environment variable is sometimes already defined which causes the
2393 * main.c (debug_signal_handler): Only define this function if
2394 SIGUSR1 is available.
2396 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2398 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2399 * README.OS2.template: Documentation updates.
2400 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2401 link line for safety.
2402 * maintMakefile (build.sh.in): Remove an extraneous ")".
2403 * job.c (child_execute_job): Close saved FDs.
2404 * job.c (exec_command) [OS/2]: exec_command(): If the command
2405 can't be exec'ed and if the shell is not Unix-sh, then try again
2406 with argv = { "cmd", "/c", ... }. Normally, this code is never
2407 reached for the cmd shell unless the command really doesn't exist.
2408 (construct_command_argv_internal) [OS/2]: The code for cmd
2409 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2410 The CMD builtin commands are case insensitive so use strcasecmp().
2412 2004-03-19 Paul D. Smith <psmith@gnu.org>
2414 * read.c (do_define): Re-order line counter increment so the count
2415 is accurate (we were losing one line per define). Reported by
2416 Dave Yost <Dave@Yost.com>.
2418 2004-03-06 Paul D. Smith <psmith@gnu.org>
2420 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2422 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2423 * misc.c (message,error,fatal): Ditto.
2424 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2425 * config.h.W32.template: Ditto.
2426 * config.h-vms.template: Ditto.
2427 * config.ami.template: Ditto.
2429 2004-03-04 Paul D. Smith <psmith@gnu.org>
2431 * README.template: Add a note about broken /bin/sh on SunOS
2432 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2434 * misc.c (message, error, fatal): Don't use "..." if we're using
2435 varargs. ansi2knr should handle this but it doesn't work: it
2436 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2437 done. On many systems (SunOS for example) va_dcl is a #define.
2438 So, force the use of the non-"..." version on pre-ANSI compilers.
2440 * maintMakefile (sign-dist): Create some rules to help automate
2441 the new GNU ftp upload method.
2443 2004-02-24 Paul D. Smith <psmith@gnu.org>
2445 * config.h.W32.template: Add HAVE_STDARG_H
2446 * config.h-vms.template: Ditto.
2447 * config.ami.template: Ditto.
2449 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2451 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2452 * build_w32.bat: Remove extra "+".
2454 2004-02-23 Paul D. Smith <psmith@gnu.org>
2456 * make.h: Create an UNUSED macro to mark unused parameters.
2457 * (many): Clean up warnings by applying UNUSED, fixing
2458 signed/unsigned incompatibilities, etc.
2460 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2462 * filedef.h: Name the command_state enumeration.
2463 * file.c (set_command_state): Use the enumeration in the function
2466 * configure.in: Explicitly set SET_MAKE to empty, to disable
2467 MAKE=make even when no make already exists. Fix bug #3823.
2469 2004-02-22 Paul D. Smith <psmith@gnu.org>
2471 * maintMakefile: Perl script to clean up all non-CVS files. Use
2472 it on all the subdirectories for the cvs-clean target.
2474 * main.c (decode_switches): Require non-empty strings for all our
2475 string command-line options. Fixes Debian bug # 164165.
2477 * configure.in: Check for stdarg.h and varargs.h.
2478 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2479 for printing messages.
2480 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2485 A number of patches for OS/2 support from Andreas Buening
2486 <andreas.buening@nexgo.de>:
2488 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2489 disable the SIGCHLD handler.
2490 (reap_children) [OS/2]: Remove special handling of job_rfd.
2491 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2492 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2493 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2494 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2495 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2498 2004-02-21 Paul D. Smith <psmith@gnu.org>
2500 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2501 <mail@kristov.de> reports that if process_begin() fails we don't
2502 handle the error condition correctly in all cases.
2503 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2504 to have a newline on the message.
2506 * job.c (construct_command_argv_internal): Add "test" to UNIX
2507 sh_cmds[]. Fixes Savannah bug # 7606.
2509 2004-02-04 Paul D. Smith <psmith@gnu.org>
2511 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2512 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2513 Hartmut Becker <Hartmut.Becker@hp.com>.
2515 2004-01-21 Paul D. Smith <psmith@gnu.org>
2517 * job.c (load_too_high): Implement an algorithm to control the
2518 "thundering herd" problem when using -l to control job creation
2519 via the load average. The system only recomputes the load once a
2520 second but we can start many jobs in a second. To solve this we
2521 keep track of the number of jobs started in the last second and
2522 apply a weight to try to guess what a correct load would be.
2523 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2524 Also fixes bug #4693.
2525 (reap_children): Decrease the job count for this second.
2526 (start_job_command): Increase the job count for this second.
2528 * read.c (conditional_line): Expand the text after ifn?def before
2529 checking to see if it's a single word. Fixes bug #7257.
2531 2004-01-09 Paul D. Smith <psmith@gnu.org>
2533 * file.c (print_file): Recurse to print all targets in
2534 double-colon rules. Fixes bug #4518, reported (with patch) by
2535 Andrew Chatham <chatham@google.com>.
2537 2004-01-07 Paul D. Smith <psmith@gnu.org>
2539 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2540 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2541 AC_FUNC_SETVBUF_REVERSED.
2543 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2544 (MAKE Variable): Fix Savannah bug #4898.
2546 * job.c (construct_command_argv_internal): Add "!" to the list of
2547 shell escape chars. POSIX sh allows it to appear before a
2548 command, to negate the exit code. Fixes bug #6404.
2550 * implicit.c (pattern_search): When matching an implicit rule,
2551 remember which dependencies have the ignore_mtime flag set.
2552 Original fix provided in Savannah patch #2349, by Benoit
2553 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2555 2003-11-22 Paul D. Smith <psmith@gnu.org>
2557 * README.W32.template (Outputs): Clarification on -j with
2558 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2561 2003-11-02 Paul D. Smith <psmith@gnu.org>
2563 * function.c (func_if): Strip all the trailing whitespace from the
2564 condition, then don't expand it. Fixed bug # 5798.
2566 * expand.c (recursively_expand_for_file): If we're expanding a
2567 variable with no file context, then use the variable's context.
2570 2003-10-21 Paul D. Smith <psmith@gnu.org>
2572 * main.c (log_working_directory): Add newlines to printf()s.
2574 * README.cvs: Add a note to ignore warnings during autoreconf.
2576 * maintMakefile (po_repo): Set a new URL for PO file updates.
2577 (get-config/config.guess get-config/config.sub): Get these files
2578 from the Savannah config project instead of ftp.gnu.org.
2580 2003-10-05 Paul Eggert <eggert@twinsun.com>
2582 * main.c (main): Avoid potential subscript error if environ has
2585 2003-08-22 Paul D. Smith <psmith@gnu.org>
2587 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2588 systems which don't yet implement the C89 standard :-/.
2590 2003-07-18 Paul D. Smith <psmith@gnu.org>
2592 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2593 [WINDOWS32]: Initialize hash.
2595 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2597 * dir.c (read_dirstream): Provide a workaround for broken versions of
2598 the MinGW dirent structure.
2600 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2602 * w32/include/dirent.h: Add __MINGW32__ filter.
2604 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2606 * make.h: Add global declaration of *make_host.
2607 * main.c (print_usage): Remove local declaration of *make_host.
2608 (print_version): Display "This program built for ..." after Copyright
2611 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2613 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2614 execution of "makeinfo --html make.texi".
2616 2003-04-30 Paul D. Smith <psmith@gnu.org>
2618 * build.template: Make some changes to maybe allow this script to
2619 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2621 * README.OS2.template: New file for OS/2 support. Original
2622 contributed by Andreas Buening.
2623 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2626 2003-04-19 Paul D. Smith <psmith@gnu.org>
2628 Fix bug #1405: allow a target to match multiple pattern-specific
2631 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2632 variable.c, where they've always belonged.
2633 * rule.h: Move the prototypes and struct pattern_var as well.
2634 * variable.c (initialize_file_variables): Invoke
2635 lookup_pattern_var() in a loop, until no more matches are found.
2636 If a match is found, create a new variable set for the target's
2637 pattern variables. Then merge the contents of each matching
2638 pattern variable set into the target's pattern variable set.
2639 (lookup_pattern_var): Change this function to be usable
2640 in a loop. It takes a starting position: if NULL, start at the
2641 beginning; if non-NULL, start with the pattern variable after that
2642 position, and return the next matching pattern.
2643 (create_pattern_var): Create a unique instance of
2644 pattern-specific variables for every definition in the makefile.
2645 Don't combine the same pattern together. This allows us to
2646 process the variable handling properly even when the same pattern
2647 is used multiple times.
2648 (parse_variable_definition): New function: break out the parsing
2649 of a variable definition line from try_variable_definition.
2650 (try_variable_definition): Call parse_variable_definition to
2652 (print_variable_data_base): Print out pattern-specific variables.
2653 * variable.h (struct variable): Remember when a variable is
2654 conditional. Also remember its flavor.
2655 (struct pattern_var): Instead of keeping a variable set, we just
2656 keep a single variable for each pattern.
2657 * read.c (record_target_var): Each pattern variable contains only a
2658 single variable, not a set, so create it properly.
2659 * doc/make.texi (Pattern-specific): Document the new behavior.
2661 2003-04-17 Paul D. Smith <psmith@gnu.org>
2663 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2664 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2665 file/directory naming rules for VMS so I can't tell whether this
2668 2003-04-09 Paul D. Smith <psmith@gnu.org>
2670 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2671 DOS-style pathnames: backslash separators and drive specifiers.
2673 2003-03-28 Paul D. Smith <psmith@gnu.org>
2675 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2676 the intermediate flag on all targets. Fixes bug #2515.
2678 2003-03-24 Paul D. Smith <psmith@gnu.org>
2680 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2681 Upgrade to autoconf 2.57 and automake 1.7.3.
2683 * job.c: More OS/2 changes from Andreas Buening.
2685 * file.c (print_file): Fix variable initialization.
2688 * remake.c (notice_finished_file):
2690 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2691 some calls (like readdir()) return NULL in valid situations
2692 without resetting errno. Fixes bug #2846.
2694 2003-02-25 Paul D. Smith <psmith@gnu.org>
2696 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2698 * job.c (_is_unixy_shell) [OS/2]: New function.
2699 Set default shell to /bin/sh.
2700 (reap_children): Close the job_rfd pipe here since we don't use a
2702 (set_child_handler_action_flags): define this to empty on OS/2.
2703 (start_job_command): Close the jobserver pipe and use
2704 child_execute_job() instead of fork/exec.
2705 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2706 rather than exec'ing, then reconfigure stdin/stdout.
2707 (exec_command): Rewrite to use spawn instead of exec. Return the
2710 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2711 in DOS. Handle the TEMP environment variable as in DOS. Don't
2712 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2713 use -j in DOS mode. Use child_execute_job() instead of
2716 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2719 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2720 prototypes that return values.
2722 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2724 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2725 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2727 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2730 2003-02-24 Paul D. Smith <psmith@gnu.org>
2732 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2733 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2734 (child_execute_job) [VMS]: Handle error status properly.
2735 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2737 * function.c (func_shell): Use EINTRLOOP() while reading from the
2738 subshell pipe (Fixes bug #2502).
2739 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2741 * main.c (main): Ditto.
2743 2003-01-30 Paul D. Smith <psmith@gnu.org>
2745 * read.c (eval): eval() was not fully reentrant, because the
2746 collapsed buffer was static. Change it to be an automatic
2747 variable so that eval() can be invoked recursively.
2749 (eval): Apply patch # 1022: fix memory reference error on long
2750 target-specific variable lines.
2751 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2753 * function.c (check_numeric): Combine the is_numeric() function
2754 into this function, since it's only called from one place.
2755 Constify this function. Have it print the incorrect string in the
2756 error message. Fixes bug #2407.
2757 (strip_whitespace): Constify.
2758 (func_if): Constify.
2759 * expand.c (expand_argument): Constify.
2761 2003-01-29 Paul D. Smith <psmith@gnu.org>
2763 Fix bug # 2169, also reported by other people on various systems.
2765 * make.h: Some systems, such as Solaris and PTX, do not fully
2766 implement POSIX-compliant SA_RESTART functionality; important
2767 system calls like stat() and readdir() can still fail with EINTR
2768 even if SA_RESTART has been set on the signal handler. So,
2769 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2770 EINTR for system calls which return -1 or 0 (NULL), respectively,
2772 Also, remove the old atomic_stat()/atomic_readdir() and
2773 HAVE_BROKEN_RESTART handling.
2775 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2777 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2778 * remake.c (touch_file): Ditto.
2780 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2781 * read.c (construct_include_path): Ditto.
2782 * remake.c (name_mtime): Ditto.
2783 * vpath.c (selective_vpath_search): Ditto.
2784 * dir.c (find_directory): Ditto.
2785 (local_stat): Ditto.
2786 (find_directory): Use ENULLLOOP() to wrap opendir().
2787 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2789 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2790 atomic_readdir() handling.
2792 2003-01-22 Paul D. Smith <psmith@gnu.org>
2794 * function.c (func_call): Fix Bug #1744. If we're inside a
2795 recursive invocation of $(call ...), mask any of the outer
2796 invocation's arguments that aren't used by this one, so that this
2797 invocation doesn't "inherit" them accidentally.
2799 2002-12-05 Paul D. Smith <psmith@gnu.org>
2801 * function.c (subst_expand): Valery Khamenia reported a
2802 pathological performance hit when doing substitutions on very
2803 large values with lots of words: turns out we were invoking
2804 strlen() a ridiculous number of times. Instead of having each
2805 call to sindex() call strlen() again, keep track of how much of
2806 the text we've seen and pass the length to sindex().
2808 2002-11-19 Paul D. Smith <psmith@gnu.org>
2810 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2813 2002-11-16 Paul D. Smith <psmith@gnu.org>
2815 * NMakefile.template (OBJS): Add hash.c object file.
2816 * SMakefile.template (srcs): Ditto.
2817 * Makefile.ami (objs): Ditto.
2818 * build_w32.bat: Ditto.
2820 * Makefile.DOS.template: Remove extra dependencies.
2822 2002-10-25 Paul D. Smith <psmith@gnu.org>
2824 * expand.c (install_variable_buffer): New function. Install a new
2825 variable_buffer context and return the previous one.
2826 (restore_variable_buffer): New function. Free the current
2827 variable_buffer context and put a previously saved one back.
2828 * variable.h: Prototypes for {install,restore}_variable_buffer.
2829 * function.c (func_eval): Push a new variable_buffer context
2830 before we eval, then restore the old one when we're done.
2833 * read.c (install_conditionals): New function. Install a new
2834 conditional context and return the previous one.
2835 (restore_conditionals): New function. Free the current
2836 conditional context and put a previously saved one back.
2837 (eval): Use the {install,restore}_conditionals for "include"
2839 (eval_buffer): Use {install,restore}_conditionals to preserve the
2840 present conditional state before we evaluate the buffer.
2843 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2845 (Recursion): Add a variable index entry for CURDIR.
2847 * README.cvs: Update to appropriate versions.
2848 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2849 don't need to copy loadavg.c: automake is smart enough to create
2850 it for me. Still have a bug in automake related to ansi2knr tho.
2852 2002-10-14 Paul D. Smith <psmith@gnu.org>
2854 * remake.c (notice_finished_file): Only touch targets if they have
2855 at least one command (as per POSIX). Resolve Bug #1418.
2857 * *.c: Convert to using ANSI C-style function definitions.
2858 * Makefile.am: Enable the ansi2knr feature of automake.
2859 * configure.in: ditto.
2861 2002-10-13 Paul D. Smith <psmith@gnu.org>
2863 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2864 for automatic variable values like $^, etc. In the case of very
2865 large lists of prerequisites this causes problems. Instead reuse
2866 a static buffer (resizeable) for each variable.
2868 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2869 target-specific variable definitions. Check for it and set an
2871 (record_target_var): Set the export field to v_export if the
2872 "exported" flag is set.
2873 * doc/make.texi (Target-specific): Document the ability to use
2876 * doc/make.texi: Change the name of the section on automatic
2877 variables from "Automatic" to "Automatic Variables". Added text
2878 clarifying the scope of automatic variables.
2880 2002-10-04 Paul D. Smith <psmith@gnu.org>
2882 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2884 (record_files): Ditto.
2886 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2887 the search for the '=' to only within the enclosing parens.
2889 2002-10-03 Paul D. Smith <psmith@gnu.org>
2891 Version 3.80 released.
2893 * dir.c: Change hash functions to use K&R function definition style.
2894 * function.c: Ditto.
2896 * variable.c: Ditto.
2898 Update to automake 1.7.
2900 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2901 (pdf): Remove this target as automake now provides one.
2903 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2905 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2907 * makefile.com: Updates for GNU make 3.80.
2908 * makefile.vms: Ditto.
2910 2002-09-23 Paul D. Smith <psmith@gnu.org>
2912 * read.c (enum make_word_type): Remove w_comment.
2913 (get_next_mword): Don't treat comment characters as special; where
2914 this function is used we will never see a comment (it's stripped
2915 before we get here) and treating comments specially means that
2916 targets like "foo\#bar" aren't handled properly.
2918 2002-09-18 Paul D. Smith <psmith@gnu.org>
2920 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2922 * read.c (eval): Expansion of arguments to export/unexport was
2923 ignoring all arguments after the first one. Change the algorithm
2924 to expand the whole line once, then parse the results.
2926 2002-09-17 Paul D. Smith <psmith@gnu.org>
2928 Fix Bug #940 (plus another bug I found while looking at this):
2930 * read.c (record_target_var): enter_file() will add a new entry if
2931 it's a double-colon target: we don't want to do that in this
2932 situation. Invoke lookup_file() and only enter_file() if it does
2933 not already exist. If the file we get back is a double-colon then
2934 add this variable to the "root" double-colon target.
2936 * variable.c (initialize_file_variables): If this file is a
2937 double-colon target but is not the "root" target, then initialize
2938 the root and make the root's variable list the parent of our
2941 2002-09-13 Paul D. Smith <psmith@gnu.org>
2943 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2945 * hash.c (round_up_2): Get rid of a warning.
2947 2002-09-12 Paul D. Smith <psmith@gnu.org>
2949 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2950 so it doesn't complain about getloadavg.c.
2952 * commands.c (set_file_variables): Make sure we always alloca() at
2953 least 1 character for the value of $? (for '\0').
2955 2002-09-11 Paul D. Smith <psmith@gnu.org>
2957 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2958 macro to use RESULT instead of the incorrect _RESULT_.
2960 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2961 and atomic_readdir(). We need to #include dirent.h to get this to
2963 * misc.c (atomic_readdir): Fix typos.
2965 2002-09-10 Paul D. Smith <psmith@gnu.org>
2967 * read.c (eval): Expand variable lists given to export and
2968 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2969 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2971 * doc/make.texi (Variables/Recursion): Document this.
2972 (Conditional Syntax): And here.
2974 2002-09-09 Paul D. Smith <psmith@gnu.org>
2976 * configure.in: Check for memmove().
2978 2002-09-07 Paul D. Smith <psmith@gnu.org>
2980 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2981 Michael Sterrett <msterret@coat.com> reports that while it has
2982 SA_RESTART, it does not work properly.
2984 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2985 that invokes stat() and loops to do it again if it returns EINTR.
2986 (atomic_readdir): Ditto, with readdir().
2988 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2989 and readdir() to atomic_stat() and atomic_readdir().
2991 2002-09-04 Paul D. Smith <psmith@gnu.org>
2993 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2994 reports that GNU make sometimes doesn't recognize that targets can
2995 be made, when directories can be created as prerequisites. He
2996 reports that changing the order of predicates in the DEP->changed
2997 flag test so that lookup_file() is always performed, solves this
3000 2002-08-08 Paul D. Smith <psmith@gnu.org>
3002 * configure.in: Require a newer version of gettext.
3004 * misc.c (perror_with_name): Translate the format string (for
3005 right-to-left language support).
3006 (pfatal_with_name): Ditto.
3008 * main.c: Create a static array of strings to store the usage
3009 text. This is done to facilitate translations.
3010 (struct command_switch): Remove argdesc and description fields.
3011 (switches): Remove values for obsolete fields.
3012 (print_usage): Print each element of the usage array.
3014 * hash.c: Change function definitions to be K&R style.
3016 2002-08-02 Paul D. Smith <psmith@gnu.org>
3018 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3019 this one because it's too hard to get right. We'll look at it for
3021 * main.c (main): Don't create the .TARGETS variable.
3022 * variable.c (handle_special_var): Don't handle .TARGETS.
3024 2002-08-01 Paul D. Smith <psmith@gnu.org>
3026 * main.c (switches): Add a new option, -B (--always-make). If
3027 specified, make will rebuild all targets that it encounters even
3028 if they don't appear to be out of date.
3029 (always_make_flag): New flag.
3030 * make.h: Extern always_make_flag.
3031 * remake.c (update_file_1): Check always_make_flag; if it's set we
3032 will always rebuild any target we can, even if none of its
3033 prerequisites are newer.
3036 * doc/make.texi (Shell Function): Make it clear that make
3037 variables marked as "export" are not passed to instances of the
3040 Add new introspection variable .VARIABLES and .TARGETS.
3042 * variable.c (handle_special_var): New function. If the variable
3043 reference passed in is "special" (.VARIABLES or .TARGETS),
3044 calculate the new value if necessary. .VARIABLES is handled here:
3045 walk through the hash of defined variables and construct a value
3046 which is a list of the names. .TARGETS is handled by
3047 build_target_list().
3048 (lookup_variable): Invoke handle_special_var().
3049 * file.c (build_target_list): Walk through the hask of known files
3050 and construct a list of the names of all the ones marked as
3052 * main.c (main): Initialize them to empty (and as simple variables).
3053 * doc/make.texi (Special Variables): Document them.
3054 * NEWS: Mention them.
3056 * variable.h (struct variable): Add a new flag "exportable" which
3057 is true if the variable name is valid for export.
3058 * variable.c (define_variable_in_set): Set "exportable" when a new
3059 variable is defined.
3060 (target_environment): Use the "exportable" flag instead of
3061 re-checking the name here... an efficiency improvement.
3063 2002-07-31 Paul D. Smith <psmith@gnu.org>
3065 * config.h-vms.template: Updates to build on VMS. Thanks to
3066 Brian_Benning@aksteel.com for helping verify the build.
3067 * makefile.com: Build the new hash.c file.
3068 * hash.h: Use strcpmi(), not stricmp(), in the
3069 HAVE_CASE_INSENSITIVE_FS case.
3071 2002-07-30 Paul D. Smith <psmith@gnu.org>
3073 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3074 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3075 Reported by <Brian_Benning@aksteel.com>.
3077 2002-07-10 Paul D. Smith <psmith@gnu.org>
3079 * variable.c (pop_variable_scope): Remove variable made unused by
3080 new hash infrastructure.
3081 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3082 comparisons as well as name comparisons.
3083 * variable.h: Add a prototype for new hash_init_function_table().
3084 * file.c (lookup_file): Remove variables made unused by new hash
3086 * dir.c (directory_contents_hash_2): Missing return of hash value.
3087 (dir_contents_file_exists_p): Remove variables made unused by new
3088 hash infrastructure.
3091 Installed Greg McGary's integration of the hash functions from the
3092 GNU id-utils package:
3094 2002-07-10 Greg McGary <greg@mcgary.org>
3096 * scripts/functions/filter-out: Add literals to to the
3097 pattern space in order to add complexity, and trigger
3098 use of an internal hash table. Fix documentation strings.
3099 * scripts/targets/INTERMEDIATE: Reverse order of files
3100 passed to expected `rm' command.
3102 2002-07-10 Greg McGary <greg@mcgary.org>
3104 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h
3105 * hash.c: New file, taken from id-utils.
3106 * hash.h: New file, taken from id-utils.
3108 * make.h (HASH, HASHI): Remove macros.
3109 (find_char_unquote): Change arglist in decl.

3119 * main.c (initialize_global_hash_tables): New function.
3120 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
3121 * misc.c (remove_comments): Pass char constants to find_char_unquote.
3122 * remake.c (notice_finished_file): Update last_mtime on `prev' chain.
3124 * dir.c (hash.h): New #include.
3125 (struct directory_contents) [next, files]: Remove members.
3126 [ctime]: Add member for VMS. [dirfiles]: Add hash-table member.
3127 (directory_contents_hash_1, directory_contents_hash_2,
3128 directory_contents_hash_cmp): New functions.
3129 (directories_contents): Change type to `struct hash_table'.
3130 (struct directory) [next]: Remove member.
3131 (directory_hash_1, directory_hash_2, directory_hash_cmp): New funcs.

3160 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions.
3161 (struct a_pattern): New struct.
3162 (func_filter_filterout): Pass through patterns noting boundaries
3163 and '%', if present. Note a_word length. Use a hash table if
3164 arglists are large enough to justify cost.
3165 (function_table_init): Renamed from function_table.
3166 (function_table): Declare as `struct hash_table'.
3167 (FUNCTION_TABLE_ENTRIES): New constant.

3172 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
3173 (uniquize_deps): Use hash table to efficiently identify duplicates.
3174 (find_char_unquote): Accept two char-constant stop chars, rather
3175 than a string constant, avoiding zillions of calls to strchr.
3176 Tighten inner search loops to test only for desired delimiters.
3178 * variable.c (variable_hash_1, variable_hash_2,
3179 variable_hash_cmp): New functions.

3194 2002-07-10 Paul D. Smith <psmith@gnu.org>
3196 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3197 prerequisite list. A real SysV make will expand the entire
3198 prerequisites list _twice_: we don't do that as it's a big
3199 backward-compatibility problem. We only replace those specific
3202 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3203 references left in the list of prerequisites. Check for .POSIX as
3204 we record targets, so we can disable non-POSIX behavior while
3205 reading makefiles as well as running them.
3206 (eval): Check the prerequisite list to see if we have anything
3207 that looks like a SysV prerequisite variable reference.
3209 2002-07-09 Paul D. Smith <psmith@gnu.org>
3211 * doc/make.texi (Prerequisite Types): Add a new section describing
3212 order-only prerequisites.
3214 * read.c (uniquize_deps): If we have the same file as both a
3215 normal and order-only prereq, get rid of the order-only prereq,
3216 since the normal one supersedes it.
3218 2002-07-08 Paul D. Smith <psmith@gnu.org>
3220 * AUTHORS: Added Greg McGary to the AUTHORS file.
3221 * NEWS: Blurbed order-only prerequisites.
3222 * file.c (print_file): Show order-only deps properly when printing
3225 * maintMakefile: Add "update" targets for wget'ing the latest
3226 versions of various external files. Taken from Makefile.maint in
3229 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3230 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3232 2002-07-07 Paul D. Smith <psmith@gnu.org>
3234 * po/*.po: Remove. We'll use wget to retrieve them at release
3237 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3238 rather than a shell you get an exception. Make sure we look up
3239 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3241 * remake.c (notice_finished_file): Fix handling of -t flag.
3242 Patch provided by Henning Makholm <henning@makholm.net>.
3244 * implicit.c (pattern_search): Some systems apparently run short
3245 of stack space, and using alloca() in this function caused an
3246 overrun. I modified it to use xmalloc() on the two variables
3247 which seemed like they might get large. Fixes Bug #476.
3249 * main.c (print_version): Update copyright notice to conform with
3251 (print_usage): Update help output.
3253 * function.c (func_eval): Create a new make function, $(eval
3254 ...). Expand the arguments, put them into a buffer, then invoke
3255 eval_buffer() on the resulting string.
3256 (func_quote): Create a new function, $(quote VARNAME). Inserts
3257 the value of the variable VARNAME without expanding it any
3260 * read.c (struct ebuffer): Change the linebuffer structure to an
3261 "eval buffer", which can be either a file or a buffer.
3262 (eval_makefile): Move the code in the old read_makefile() which
3263 located a makefile into here: create a struct ebuffer with that
3264 information. Have it invoke the new function eval() with that
3266 (eval_buffer): Create a new function that creates a struct ebuffer
3267 that holds a string buffer instead of a file. Have it invoke
3268 eval() with that ebuffer.
3269 (eval): New function that contains the guts of the old
3270 read_makefile() function: this function parses makefiles. Obtains
3271 data to parse from the provided ebuffer. Some modifications to
3272 make the flow of the function cleaner and clearer. Still could
3273 use some work here...
3274 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3275 contents of the define/endef variable from the ebuffer.
3276 (readstring): Read the next line from a string-style ebuffer.
3277 (readline): Read the next line from an ebuffer. If it's a string
3278 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3281 * dep.h (eval_buffer): Prototype eval_buffer();
3283 * variable.c (do_variable_definition): Make sure that all
3284 non-target-specific variables are registered in the global set.
3285 If we're invoked from an $(eval ...) we might be inside a $(call
3286 ...) or other function which has pushed a variable scope; we still
3287 want to define our variables from evaluated makefile code in the
3290 2002-07-03 Greg McGary <greg@mcgary.org>
3292 * dep.h (struct dep) [ignore_mtime]: New member.
3293 [changed]: convert to a bitfield.
3294 * implicit.c (pattern_search): Zero ignore_mtime.
3295 * main.c (main, handle_non_switch_argument): Likewise.
3296 * rule.c (convert_suffix_rule): Likewise.
3297 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3298 (read_makefile): Parse '|' in prerequisite list.
3299 (uniquize_deps): Consider ignore_mtime when comparing deps.
3300 * remake.c (update_file_1, check_dep): Don't force remake for
3301 dependencies that have d->ignore_mtime.
3302 * commands.c (FILE_LIST_SEPARATOR): New constant.
3303 (set_file_variables): Don't include a
3304 prerequisite in $+, $^ or $? if d->ignore_mtime.
3307 2002-06-18 Paul D. Smith <psmith@gnu.org>
3309 * make.texinfo: Updates for next revision. New date/rev/etc.
3310 Recreate all Info menus. Change license on the manual to the GNU
3311 Free Documentation License. A number of typos.
3312 (Variables Simplify): Don't use "-" before it's defined.
3313 (Automatic Prerequisites): Rewrite the target example to work
3314 properly if the compile fails. Remove incorrect comments about
3315 how "set -e" behaves.
3316 (Text Functions): Move the "word", "wordlist", "words", and
3317 "firstword" functions here, from "File Name Functions".
3318 * make-stds.texi: Update from latest GNU version.
3319 * fdl.texi: (created) Import the latest GNU version.
3321 2002-06-06 Paul D. Smith <psmith@gnu.org>
3323 * variable.c (do_variable_definition): New function: extract the
3324 part of try_variable_definition() that actually sets the value
3325 into a separate function.
3326 (try_variable_definition): Call do_variable_definition() after
3327 parsing the variable definition string.
3328 (define_variable_in_set): Make the name argument const.
3330 * variable.h (enum variable_flavor): Make public.
3331 (do_variable_definition): Create prototype.
3333 * read.c (read_all_makefiles): Create a new built-in variable,
3335 (read_makefile): Add each makefile read in to this variable value.
3337 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3339 * Makefile.DOS.template: Tweak according to changes in the
3340 distribution. Add back the dependencies of *.o files.
3342 * configh.dos.template: Synchronize with config.h.in.
3344 2002-05-09 Paul D. Smith <psmith@gnu.org>
3346 * file.c (file_timestamp_now): Use K&R function declaration.
3348 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3349 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3350 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3351 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3352 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3353 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3354 nlist.n_name is a pointer rather than an array.
3356 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3357 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3358 * configure.in: Use it instead of the old version.
3360 * main.c (main): Prefer setvbuf() to setlinebuf().
3362 2002-05-08 Paul D. Smith <psmith@gnu.org>
3364 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3365 (loadavg_LDADD): Ditto.
3367 2002-04-29 Paul D. Smith <psmith@gnu.org>
3369 * expand.c (recursively_expand_for_file): Rename
3370 recursively_expand() to recursively_expand_for_file() and provide
3371 an extra argument, struct file. If the argument is provided, set
3372 the variable scope to that of the file before expanding.
3373 * variable.h (recursively_expand): Make this a macro that invokes
3374 recursively_expand_for_file() with a NULL file pointer.
3375 * variable.c (target_environment): Call the renamed function and
3376 provide the current file context.
3377 Fixes Debian bug #144306.
3379 2002-04-28 Paul D. Smith <psmith@gnu.org>
3381 Allow $(call ...) user-defined variables to be self-referencing
3382 without throwing an error. Allows implementation of transitive
3383 closures, among other possibly useful things.
3384 Requested by: Philip Guenther <guenther@sendmail.com>
3386 * variable.h (struct variable): Add a new field: exp_count, and
3387 new macros to hold its size and maximum value.
3388 (warn_undefined): Make this a macro.
3389 * variable.c (define_variable_in_set): Initialize it.
3390 * expand.c (recursively_expand): If we detect recursive expansion
3391 of a variable, check the exp_count field. If it's greater than 0
3392 allow the recursion and decrement the count.
3393 (warn_undefined): Remove this (now a macro in variable.h).
3394 * function.c (func_call): Before we expand the user-defined
3395 function, modify its exp_count field to contain the maximum
3396 number of recursive calls we'll allow. After the call, reset it
3399 2002-04-21 Paul D. Smith <psmith@gnu.org>
3401 Modified to use latest autoconf (2.53), automake (1.6.1), and
3402 gettext (0.11.1). We're using gettext's new "external" support,
3403 to avoid including libintl source with GNU make.
3405 * README.cvs: New file. Explain how to build GNU make from CVS.
3407 * configure.in: Modify checking for the system glob library.
3408 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3409 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3410 etc. will manage it correctly). Set an automake conditional
3411 USE_LOCAL_GLOB to decide whether to compile the glob library.
3413 * getloadavg.c (main): Include make.h in the "TEST" program to
3416 * Makefile.am: Remove special rules for loadavg. Replace them
3417 with Automake capabilities for building extra programs.
3419 * signame.c: This file does nothing if the system provide
3420 strsignal(). If not, it implements strsignal(). If the system
3421 doesn't define sys_siglist, then we make our own; otherwise we use
3423 * signame.h: Removed.
3425 * main.c (main): No need to invoke signame_init(). Update copyright.
3427 * ABOUT-NLS: Removed.
3428 * gettext.c: Removed.
3429 * gettext.h: Get a simplified copy from the gettext package.
3431 * i18n/*.po: Moved to po/.
3434 * config/*: Created. Contains package configuration helper files.
3435 * config.guess, config.sub: Moved to config directory.
3437 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3438 Rework to use new-style autoconf features. Use the "external"
3439 mode for gettext. Make the build.sh config file conditional on
3440 whether build.sh.in exists, to avoid autoconf errors.
3441 * acinclude.m4: Removed almost all macros as being obsolete.
3442 Rewrote remaining macros to use AC_DEFINE.
3443 * acconfig.h: Removed.
3445 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3446 conditional to handle customs support. Remove special handling
3449 2002-04-20 Paul D. Smith <psmith@gnu.org>
3451 * function.c (func_call): Don't mark the argument variables $1,
3452 etc. as recursive. They've already been fully expanded so
3453 there's no need to do it again, and doing so strips escaped $'s.
3454 Reported by Sebastian Glita <glseba@yahoo.com>.
3456 * remake.c (notice_finished_file): Walk through double-colon
3457 entries via the prev field, not the next field!
3458 Reported by Greg McGary <greg@mcgary.org>.
3460 * main.c (main): If the user specifies -q and asks for a specific
3461 target which is a makefile, we got an assert. In that case it
3462 turns out we should continue normally instead.
3464 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3466 * i18n/he.po: Installed a new translation.
3468 2002-01-07 Paul D. Smith <psmith@gnu.org>
3470 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3472 2001-12-04 Paul D. Smith <psmith@gnu.org>
3474 * i18n/ja.po: Installed an updated translation.
3476 2001-09-06 Paul Eggert <eggert@twinsun.com>
3478 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3479 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3481 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3483 (main): Get rid of any avoidable limit on stack size.
3485 2001-09-04 Paul D. Smith <psmith@gnu.org>
3487 * i18n/da.po: Installed an updated translation.
3489 2001-08-03 Paul D. Smith <psmith@gnu.org>
3491 * i18n/fr.po: Installed an updated translation.
3492 Resolves Debian bug #106720.
3494 2001-06-13 Paul D. Smith <psmith@gnu.org>
3496 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3499 2001-06-11 Paul D. Smith <psmith@gnu.org>
3501 * i18n/ko.po: Installed a new translation.
3503 2001-05-06 Paul D. Smith <psmith@gnu.org>
3505 Modify the EINTR handling.
3507 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3508 the way in which we manage the file descriptor/signal handler race
3509 trap to be more efficient.
3511 2001-05-06 Paul Eggert <eggert@twinsun.com>
3513 Restart almost all system calls that are interrupted, instead
3514 of worrying about EINTR. The lone exception is the read() for
3517 * configure.in (HAVE_SA_RESTART): New macro.
3518 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3519 * main.c (main): Use SA_RESTART instead of the old,
3520 nonstandard SA_INTERRUPT.
3522 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3523 * main.c (bsd_signal): New function or macro,
3524 if the implementation doesn't supply it.
3525 (The bsd_signal function will be in POSIX 1003.1-200x.)
3526 (HANDLESIG): Remove.
3527 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3529 * make.h (EINTR_SET): Remove.
3530 (SA_RESTART): New macro.
3532 * arscan.c (ar_member_touch): Don't worry about EINTR.
3533 * function.c (func_shell): Likewise.
3534 * job.c (reap_children, free_child, new_job): Likewise.
3535 * main.c (main): Likewise.
3536 * remake.c (touch_file, name_mtime): Likewise.
3538 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3539 if fstat failed with errno!=EINTR, the error was ignored.
3541 * job.c (set_child_handler_action_flags): New function.
3542 (new_job): Use it to temporarily clear the SIGCHLD action flags
3543 while reading the token.
3545 2001-05-02 Paul D. Smith <psmith@gnu.org>
3547 * job.c (start_job_command): Don't add define/endef per-line flags
3548 to the top-level flags setting.
3550 2001-04-03 Paul D. Smith <psmith@gnu.org>
3552 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3553 bit on error, so check for odd return values, not non-0 return
3555 (VMS_get_member_info): Calculate the timezone differences correctly.
3556 Reported by John Fowler <jfowler@nyx.net>.
3559 2001-03-14 Paul D. Smith <psmith@gnu.org>
3561 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3562 value before invoking define_variable().
3563 Reported by John Fowler <jfowler@nyx.net>.
3565 2001-02-07 Paul D. Smith <psmith@gnu.org>
3567 * read.c (record_target_var): If we reset the variable due to a
3568 command-line variable setting overriding it, turn off the "append"
3571 2001-01-17 Paul D. Smith <psmith@gnu.org>
3573 * variable.c (lookup_variable) [VMS]: When getting values from the
3574 environment, allocate enough space for the _value_ plus escapes,
3575 not enough space for the name plus escapes :-/.
3576 Reported by John Fowler <jfowler@nyx.net>.
3578 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3579 warnings that make generates, so it doesn't look like an error.
3580 Reported by Karl Berry <karl@gnu.org>.
3583 Fix for PR/2020: Rework appended target-specific variables. I'm
3584 fairly confident this algorithm is finally correct.
3586 * expand.c (allocated_variable_append): Rewrite. Instead of
3587 expanding each appended variable then adding all the expanded
3588 strings together, we append all the unexpanded values going up
3589 through the variable set contexts, then expand the final result.
3590 This behaves just like non-target-specific appended variable
3591 values, while the old way didn't in various corner cases.
3592 (variable_append): New function: recursively append the unexpanded
3593 value of a variable, walking from the outermost variable scope to
3595 * variable.c (lookup_variable): Remove the code that looked up the
3596 variable set list if the found variable was "append". We don't
3598 (lookup_variable_in_set): Make this non-static so we can use it
3600 (try_variable_definition): Use lookup_variable_in_set() rather
3601 than faking out current_variable_set_list by hand (cleanup).
3602 * variable.h: Add a prototype for the now non-static
3603 lookup_variable_in_set().
3605 2000-11-17 Paul D. Smith <psmith@gnu.org>
3607 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3608 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3609 before throwing a fit.
3611 2000-11-17 Paul D. Smith <psmith@gnu.org>
3613 * read.c (readline): CRLF calculations had a hole, if you hit the
3614 buffer grow scenario just right. Reworked the algorithm to avoid
3615 the need for len or lastlen at all. Problem description with
3616 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3618 2000-10-24 Paul D. Smith <psmith@gnu.org>
3620 * gettext.c (SWAP): Declare this with the prototype, otherwise
3621 some systems don't work (non-32-bit? Reported for Cray T3E).
3622 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3624 2000-10-05 Paul D. Smith <psmith@gnu.org>
3626 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3627 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3629 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3631 2000-09-22 Paul D. Smith <psmith@gnu.org>
3633 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3634 parts of the real gettext.h here, and we expect to really include
3635 the real gettext.h later. If we keep this #define, it's ignored.
3637 2000-09-21 Paul D. Smith <psmith@gnu.org>
3639 * main.c (log_working_directory): Rework the text to use complete
3640 sentences, to make life simpler for the translators.
3642 2000-08-29 Paul D. Smith <psmith@gnu.org>
3644 * file.c (remove_intermediates): Print a debug message before we
3645 remove intermediate files, so the user (if she uses -d) knows
3648 2000-08-21 Paul D. Smith <psmith@gnu.org>
3650 * variable.c (try_variable_definition): Change how we handle
3651 target-specific append variable defns: instead of just setting the
3652 value, expand it as an append _but_ only within the current
3653 target's context. Otherwise we lose all but the last value if the
3654 variable is appended more than once within the current target
3655 context. Fixes PR/1831.
3657 2000-08-16 Paul D. Smith <psmith@gnu.org>
3659 * function.c (func_shell): Nul-terminate the buffer before
3660 printing an exec error message (just in case it's not!).
3661 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3663 2000-07-25 Paul D. Smith <psmith@gnu.org>
3665 * job.c (construct_command_argv_internal): Add "~" to the list of
3666 sh_chars[] which disallow optimizing out the shell call.
3668 2000-07-23 Paul Eggert <eggert@twinsun.com>
3670 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3671 supersedes --disable-nsec-timestamps.
3672 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3673 * README: Remove --disable-nsec-timestamps.
3675 * filedef.h (struct file.low_resolution_time): New member.
3676 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3677 * remake.c (update_file_1):
3678 Avoid spurious rebuilds due to low resolution time stamps,
3679 generalizing the earlier code that applied only to archive members.
3680 (f_mtime): Archive members always have low resolution time stamps.
3682 * configure.in: Remove --disable-nsec-timestamps, as this has
3683 been superseded by .LOW_RESOLUTION_TIME.
3685 2000-07-23 Paul Eggert <eggert@twinsun.com>
3687 * configure.in (enable_nsec_timestamps): Renamed from
3688 make_cv_nsec_timestamps, since enable/disable options
3689 shouldn't be cached.
3691 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3692 and Paul Eggert <eggert@twinsun.com>
3694 * file.c (file_timestamp_now):
3695 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3696 so that clock_gettime is not linked unless needed.
3698 * filedef.h (FILE_TIMESTAMP_HI_RES):
3699 Remove definition; "configure" now does this.
3701 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3702 to before high resolution file timestamp check,
3703 since that check now uses uintmax_t.
3704 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3705 high resolution file timestamps.
3706 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3707 so that we don't link in clock_gettime unnecessarily.
3709 2000-07-17 Paul D. Smith <psmith@gnu.org>
3711 * i18n/ja.po: New version of the translation file.
3713 2000-07-07 Paul D. Smith <psmith@gnu.org>
3715 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3716 the offset calculation.
3717 (name_mtime): Replace EINTR test with EINTR_SET macro.
3719 2000-07-07 Paul Eggert <eggert@twinsun.com>
3723 * remake.c (update_file_1):
3724 Avoid spurious rebuilds of archive members due to their
3725 timestamp resolution being only one second.
3726 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3727 the clock's resolution being lower than file timestamps'.
3728 When warning about future timestamps, report only the discrepancy,
3729 not the absolute value of the timestamp and the current time.
3731 * file.c (file_timestamp_now): New arg RESOLUTION.
3732 * filedef.h (file_timestamp_now): Likewise.
3733 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3735 2000-07-05 Paul D. Smith <psmith@gnu.org>
3737 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3738 to listp. Fixes PR/1793.
3740 2000-06-26 Paul Eggert <eggert@twinsun.com>
3742 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3744 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3746 * remake.c (f_mtime): Remove unused var memtime.
3748 2000-06-25 Martin Buchholz <martin@xemacs.org>
3750 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3751 Ran spell-check on make.texinfo.
3753 2000-06-23 Paul D. Smith <psmith@gnu.org>
3755 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3756 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3757 * make.h: Define these macros.
3759 * Version 3.79.1 released.
3761 * configure.in: Add a new option, --disable-nsec-timestamps, to
3762 avoid using sub-second timestamps on systems that support it. It
3763 can lead to problems, e.g. if your makefile relies on "cp -p".
3764 * README.template: Document the issue with "cp -p".
3766 * config.guess, config.sub: Updated.
