1 2009-10-07 Boris Kolpackov <boris@codesynthesis.com>
3 * read.c (do_undefine): Free the expanded variable name.
5 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
6 to normal upgrade logic from dep_hash_cmp to set_file_variables.
8 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
10 * dep.h (uniquize_deps): Remove.
12 * read.c (uniquize_deps): Merge into set_file_variables in
14 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
16 * commands.c (set_file_variables): Avoid modifying the dep
17 chain to achieve uniqueness. Fixes savannah bug 25780.
19 * implicit.c (pattern_search): Instead of re-setting all automatic
20 variables for each rule we try, just update $*.
22 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
24 * variable.h (undefine_variable_in_set): New function declaration.
25 (undefine_variable_global): New macro.
27 * variable.c (undefine_variable_in_set): New function implementation.
29 * read.c (vmodifiers): Add undefine_v modifier.
30 (parse_var_assignment): Parse undefine.
31 (do_undefine): Handle the undefine directive.
32 (eval): Call do_undefine if undefine_v is set.
34 * main.c (.FEATURES): Add a keyword to indicate the new feature.
36 * doc/make.texi (Undefine Directive): Describe the new directive.
38 * NEWS: Add a note about the new directive.
40 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
42 * implicit.c (pattern_search): Initialize file variables only
43 if we need to parse a rule that requires the second expansion.
45 2009-10-03 Paul Smith <psmith@gnu.org>
47 * make.h: Include <alloca.h> even on systems where __GNUC__ is
48 defined. Not sure why it was done the other way.
49 Requested by David Boyce <dsb@boyski.com>.
51 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
53 * dep.h (dep): Add the DONTCARE bitfield.
55 * filedef.h (file):Add the NO_DIAG bitfield.
57 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
58 not struct file (a file can be a dependency of many targets,
59 some don't care, some do).
61 * remake.c (update_goal_chain): Propagate DONTCARE from struct
62 dep to struct file before updating the goal and restore it
64 (update_file): Don't prune the dependency graph if this target
65 has failed but the diagnostics hasn't been issued.
66 (complain): Scan the file's dependency graph to find the file
67 that caused the failure.
68 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
69 whether to print diagnostics.
71 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
73 2009-09-28 Paul Smith <psmith@gnu.org>
75 * doc/make.texi (Pattern Intro): Move the match algorithm
76 discussion into the "Pattern Match" node.
77 (Pattern Match): Expand on the pattern rule matching algorithm.
79 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
81 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
82 much of the command line on a single pass.
84 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
86 * varible.c (create_pattern_var): Insert variables into the
87 PATTERN_VARS list in the shortest patterns first order.
89 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
90 used to sort the rules.
91 (stemlen_compare): Compare two tryrule elements.
92 (pattern_search): Sort the rules so that they are in the shortest
95 * main.c (.FEATURES): Add a keyword to indicate the new behavior.
97 * doc/make.texi (Pattern-specific Variable Values): Describe the
98 new pattern-specific variables application order.
99 (Introduction to Pattern Rules): Describe the new pattern rules
102 * NEWS: Add a note about the new behavior.
104 2009-09-27 Paul Smith <psmith@gnu.org>
106 * doc/make.texi (Double-Colon): Mention that pattern rules with
107 double-colons have a different meaning. Savannah bug #27497.
109 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
111 * configh.dos.template: Remove unconditional definition of
112 SYS_SIGLIST_DECLARED.
113 Include <sys/version.h> because ports of GCC 4.3.0 and later no
114 longer include it, so macros like __DJGPP_MINOR__ are no longer
115 defined automatically.
117 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
118 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
119 instead of using the hardcoded ones.
120 (SUBDIRS): doc subdir added.
121 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
122 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
123 create html formated docs. texi2html may not be ported to DOS.
124 (make.info, make.dvi, make.ps, make.html): Make targets depend on
126 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
127 -I switch to look in ./ instead of ./doc.
128 (html): Target depend on html-recursive instead of make_1.html.
129 (make_1.html): Removed.
130 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
131 (all-recursive): Allow for more than one subdir in the build
133 (mostlyclean-recursive, clean-recursive, distclean-recursive)
134 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
135 (tags-recursive): Allow for more than one subdir in the build
137 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
138 targets. Enter into doc/ to produce the targets.
139 (all-am): $(INFO_DEPS) replaced by info.
141 2009-09-26 Paul Smith <psmith@gnu.org>
143 * read.c (record_files): Use free_ns() to free struct nameseq.
146 * rule.c (freerule): Use free_dep_chain().
148 * read.c (record_files): Free FILENAMES chain for implicit rules.
149 (eval): Static pattern targets go into the string cache.
151 * function.c (string_glob): Free NAME in the nameseq chain.
153 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
155 * implicit.c (pattern_search): Terminate early if we haven't
156 found any rules to try (performance improvement).
158 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
160 * implicit.c (pattern_search): Merge three parallel arrays,
161 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
162 of struct TRYRULE. In the old version the latter two arrays
163 had insufficient length.
165 2009-09-24 Paul Smith <psmith@gnu.org>
167 * implicit.c (pattern_search): Add back support for order-only
168 prerequisites for secondary expansion implicit rules, that were
169 accidentally dropped. If we find a "|", enable order-only mode
170 and set IGNORE_MTIME on all deps that are seen afterward.
171 (pattern_search): Fix memory leaks: for intermediate files where
172 we've already set the file variable and pattern variable sets, be
173 sure to either save or free them as appropriate.
175 2009-09-23 Paul Smith <psmith@gnu.org>
177 Rework the way secondary expansion is stored, for efficiency.
178 This changes secondary expansion so that ONLY WHEN we know we have
179 a possibility of needing secondary expansion, do we defer the
180 secondary expansion. This means more parsing the deps but we use
181 a lot less memory (due to the strcache). Also, this fixes
184 * read.c (eval): Don't parse the dep string here anymore.
185 (record_files): Take the dep argument as an unparsed string. If
186 secondary expansion is enabled AND the prereq string has a '$' in
187 it, then set NEED_2ND_EXPANSION and keep the entire string.
188 Otherwise, parse the dep string here to construct the dep list
189 with the names in the strcache.
191 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
192 duplicate the name string (others are in the strcache).
194 * implicit.c: Remove struct idep and free_idep_chain(): unused.
195 (struct patdeps): New structure to store prereq information.
196 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
197 which prerequisites need expansion, and expand only those.
199 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
200 and enter_prereqs(). split_prereqs() takes a fully-expanded string
201 and splits it into a DEP list, handling order-only prereqs.
202 (enter_prereqs): This function enters a list of DEPs into the file
203 database. If there's a stem defined, expand any pattern chars.
204 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
205 set. Use the above functions.
206 (snap_deps): Only perform second expansion on prereqs that need it,
207 as defined by the NEED_2ND_EXPANSION flag.
208 (print_prereqs): New function to print the prereqs
209 (print_file): Call print_prereqs() rather than print inline.
211 * hash.h (STRING_COMPARE): Take advantage of strcache() by
213 (STRING_N_COMPARE): Ditto.
214 (ISTRING_COMPARE): Ditto.
216 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
217 (parse_file_seq): Return void*
218 * read.c (parse_file_seq): Return void*.
219 (eval): Invoke macroized version of parse_file_seq()
220 * default.c (set_default_suffixes): Ditto.
221 * file.c (split_prereqs): Ditto.
222 * function.c (string_glob): Ditto.
223 * main.c (main): Ditto.
224 * rule.c (install_pattern_rule): Ditto.
226 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
228 2009-09-16 Paul Smith <psmith@gnu.org>
230 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
232 * dep.h: Create alloc_dep() / free_dep() macros.
234 * implicit.c (pattern_search): Take advantage of the new
235 parse_file_seq() to add the directory prefix to each prereq.
237 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
238 all. Avoid reversing chains. Support adding prefixes.
239 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
240 cached/non-cached results.
241 (eval): Remove multi_glob() & invoke new parse_file_seq().
242 * rule.c (install_pattern_rule): Ditto.
243 * main.c (main): Ditto.
244 * implicit.c (pattern_search): Ditto.
245 * function.c (string_glob): Ditto.
246 * file.c (parse_prereqs): Ditto.
247 * default.c (set_default_suffixes): Ditto.
249 * variable.c (parse_variable_definition): Don't run off the end of
250 the string if it ends in whitespace (found with valgrind).
252 * commands.c (set_file_variables): Keep space for all targets in
253 $? if -B is given (found with valgrind).
255 2009-09-15 Paul Smith <psmith@gnu.org>
257 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
258 (xcalloc): Add new function.
259 * make.h: New declarations.
261 * ar.c (ar_glob_match): New calling method for concat().
262 * main.c (main): Ditto.
263 (decode_env_switches): Ditto.
264 * read.c (eval_makefile): Ditto.
265 (tilde_expand): Ditto.
266 (parse_file_seq): Ditto.
267 * variable.c (target_environment): Ditto.
268 (sync_Path_environment): Ditto.
270 * ar.c (ar_glob_match): Use xcalloc().
271 * dir.c (file_impossible): Ditto.
272 * file.c (enter_file): Ditto.
273 * job.c (new_job): Ditto.
274 * read.c (parse_file_seq): Ditto.
275 * vmsfunctions.c (opendir): Ditto.
277 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
279 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
280 inside the loop that looks up environment for PATH.
282 2009-08-31 Eli Zaretskii <eliz@gnu.org>
284 * function.c (windows32_openpipe): Update envp after calling
285 sync_Path_environment.
287 2009-08-02 Paul Smith <psmith@gnu.org>
289 * remake.c (notice_finished_file): Ensure file->cmds is not null
290 before looping through them. Fixes Savannah bug #21824.
292 * doc/make.texi (Wildcard Examples): Clarify when objects is
293 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
294 (Include): Clarify the behavior of -include.
295 Fixes Savannah bug #18963.
297 2009-08-01 Paul Smith <psmith@gnu.org>
299 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
300 etc. come on the command line. Fixes Savannah bug #27093.
302 * expand.c (expand_argument): If the argument is large enough use
303 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
305 * variable.c (do_variable_definition): Avoid using alloca() to
306 hold values, which can be large. Fixes Savannah bug #23960.
308 * job.c (new_job): Use memmove() instead of strcpy() since both
309 pointers are in the same memory block. Fixes Savannah bug #27148.
310 Patch by Petr Machata.
312 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
314 * job.c (construct_command_argv_internal): Add "ulimit" and
315 "unset" to the sh_cmds for Unixy shells.
317 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
319 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
320 that set make_cv_sys_gnu_glob, so they are also correctly set
321 when the cache has been populated before.
323 2009-07-04 Eli Zaretskii <eliz@gnu.org>
325 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
326 exist, as realpath(3) does where it's supported.
328 2006-07-04 Eli Zaretskii <eliz@gnu.org>
330 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
331 (abspath): Support systems that define HAVE_DOS_PATHS (have
332 drive letters in their file names). Use IS_PATHSEP instead of a
333 literal '/' comparison. Fixes Savannah bug #26886.
335 2009-06-14 Paul Smith <psmith@gnu.org>
337 * remake.c (update_file_1): Remember the original file we marked
338 as updating, so we can clear that flag again. If we find a target
339 via vpath, FILE might change.
340 (check_dep): Ditto. Fixes Savannah bug #13529.
341 Patch by Reid Madsen <reid.madsen@tek.com>.
343 2009-06-13 Paul Smith <psmith@gnu.org>
345 * doc/make.texi (MAKEFILES Variable): Be explicit that files
346 included by MAKEFILES cannot give default goals.
347 * read.c (eval): If set_default is not set, pass the no-default-goal
348 value when we read included makefiles. Fixes Savannah bug #13401.
350 * ar.c (ar_name): Ensure that targets with empty parens aren't
351 considered archive member references: archive members must have a
352 non-empty "member" string. Fixes Savannah bug #18435.
354 * function.c (string_glob): Rely on multi_glob() to determine
355 whether files exist or not. Remove call to file_exists_p() which
356 is not always correct. Fixes Savannah bug #21231.
357 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
358 then only files that really exist will be returned.
359 * dep.h: Add new argument to multi_glob().
360 * rule.c (install_pattern_rule): Ditto.
361 * read.c (eval): Ditto.
362 * main.c (main): Ditto.
363 * implicit.c (pattern_search): Ditto.
364 * file.c (parse_prereqs): Ditto.
365 * default.c (set_default_suffixes): Ditto.
367 2009-06-09 Paul Smith <psmith@gnu.org>
369 * commands.c (set_file_variables): If always_make_flag is set,
370 always add the prereq to $?. Fixes Savannah bug #17825.
372 * remake.c (update_file_1): When rebuilding deps of FILE, also try
373 to rebuild the deps of all the also_make targets for that file.
374 Fixes Savannah bug #19108.
376 * implicit.c (pattern_search): Undo test for is_target, added by
377 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
378 Rule Search Algorithm". Fixes Savannah bug #17752.
380 * main.c (clean_jobserver): Clear the jobserver_fds options and
381 set job_slots to the default when we clean up.
382 (define_makeflags): Return the new MAKEFLAGS value.
383 (main): Reset MAKEFLAGS in the environment when we re-exec.
384 Fixes Savannah bug #18124.
386 2009-06-08 Paul Smith <psmith@gnu.org>
388 * read.c (eval): Collapse continuations post-semicolon on target-
389 specific variables. Fixes Savannah bug #17521.
391 2009-06-07 Paul Smith <psmith@gnu.org>
393 * job.c (reap_children): For older systems without waitpid() (are
394 there any of these left?) run wait(2) inside EINTRLOOP to handle
395 EINTR errors. Fixes Savannah bug #16401.
397 * (various): Debug message cleanup. Fixes Savannah bug #16469.
399 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
401 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
402 not the end, to catch second expansion $(eval ...) defining new
403 target/prereq relationships during snap_deps.
404 Fixes Savannah bug #24622.
406 * read.c (record_files): The second-expansion "f->updating" hack
407 was not completely correct: if assumed that the target with
408 commands always had prerequisites; if one didn't then the ordering
409 was messed up. Fixed for now to use f->updating to decide whether
410 to preserve the last element in the deps list... but this whole
411 area of constructing and reversing the deps list is too confusing
412 and needs to be reworked. Fixes Savannah bug #21198.
414 2009-06-06 Paul Smith <psmith@gnu.org>
416 * hash.c (hash_insert): Remove useless test for NULL.
417 Fixes Savannah bug #21823.
419 * make.h: Move SET_STACK_SIZE determination to make.h.
420 * main.c (main): New global variable, STACK_LIMIT, holds the
421 original stack limit when make was started.
422 * job.c (start_job_command): Reset the stack limit, if we changed it.
423 Fixes Savannah bug #22010.
425 * remake.c (check_dep): Only set the target's state to not-started
426 if it's not already running. Found this while testing -j10 builds
427 of glibc: various targets were being rebuilt multiple times.
428 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
431 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
432 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
435 2009-06-04 Paul Smith <psmith@gnu.org>
437 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
439 * maintMakefile: Modify access of config and gnulib Savannah
440 modules to use GIT instead of CVS.
442 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
443 Fixes Savannah bug #24655.
445 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
446 this can happen during some invocations of $(eval ...) for example.
447 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
449 2009-06-02 Paul Smith <psmith@gnu.org>
451 * configure.in: Check for fileno()
452 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
453 for the makefile file so invocations of $(shell ...) don't inherit it.
454 Fixes Savannah bug #24277.
456 2009-06-01 Paul Smith <psmith@gnu.org>
458 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
459 expansion was handled incorrectly. Rework the default goal
460 handling to save the variable only. Remove default_goal_file and
462 * read.c (eval): Check default_goal_var, not default_goal_name.
463 * read.c (record_target_var): Don't check default_goal_file here.
465 2009-05-31 Paul Smith <psmith@gnu.org>
467 * main.c (main): Expand the .DEFAULT_GOAL variable before using
468 it, and if the multi_glob() returns nothing (say it expanded to
469 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
471 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
472 $(and ..) to the reference. Fixes Savannah bug #25694.
474 * make.1: Be clear that some recipes will be executed even with -n.
475 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
477 * doc/make.texi (Override Directive): Make more clear how
478 overrides and appends interact.
479 Elucidates part of Savannah bug #26207.
481 * read.c (record_target_var): Don't reset the origin on
482 target-specific variables; try_variable_definition() will handle
483 this correctly. Fixes Savannah bug #26207.
485 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
486 Fixes Savannah bug #25712.
488 * implicit.c (pattern_search): Keep a pointer to the beginning of
489 the filename and save that instead of the constructed pointer.
490 Fixes Savannah bug #26593.
491 Patch by Mark Seaborn <mrs@mythic-beasts.com>
493 2009-05-30 Paul Smith <psmith@gnu.org>
495 * doc/make.texi (Multi-Line): Add a description of the new abilities
496 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
497 "command sequence" vs. "recipe" syntax.
498 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
499 after a define, to create variables with those flavors.
501 2009-05-25 Paul Smith <psmith@gnu.org>
503 Reworked the parser for variable assignments to allow multiple
504 modifiers, and in any order. Also allows variable and
505 prerequisites to be modifier names ('export', 'private', etc.)
507 * NEWS: Add notes about user-visible changes.
509 * read.c (struct vmodifiers): Remember what modifiers were seen.
510 (parse_var_assignment): New function to parse variable assignments.
511 (eval): Call the new function. Handle variable assignments earlier.
513 * variable.c (parse_variable_definition): Only parse; don't create var.
514 (assign_variable_definition): Call parse, then create the var.
516 2009-05-24 Paul Smith <psmith@gnu.org>
518 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
519 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
521 2009-03-14 Eli Zaretskii <eliz@gnu.org>
523 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
524 Fixes Savannah bug #25412.
526 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
527 prototype for xmalloc.
528 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
529 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
530 Loop over an array of extensions, instead of duplicating the same
531 code inline. Use SearchPath followed by CreateFile, instead of
532 the obsolete OpenFile. Fixes Savannah bug #17277.
533 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
534 to `find_file'. Fixes Savannah bug #25662.
536 2009-03-07 Eli Zaretskii <eliz@gnu.org>
538 * function.c (func_shell): Don't close pipedes[1] if it is -1.

665 2007-10-12 Eli Zaretskii <eliz@gnu.org>
667 * variable.c (do_variable_definition): Allow $(SHELL) to expand to

729 2007-08-15 Paul Smith <psmith@gnu.org>

795 Dave Korn <dave.korn@artimi.com>
797 2007-05-08 Paul Smith <psmith@gnu.org>
799 Fix Savannah bug #19656:
801 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
803 * make.h: Change all case-insensitive string compares to use
804 strcasecmp() (from POSIX). If we don't have that but do have one
805 of the others, define strcasecmp to be one of those instead. If
806 we don't have any, declare a prototype for our own version.
808 * misc.c (strcasecmp): Use this if we can't find any native
809 case-insensitive string comparison function.
810 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
811 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
813 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
814 strcasecmp() instead of stricmp().
815 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
816 instead of strcmpi().
817 * acinclude.m4: Remove the strcasecmp() check from here.
819 2007-03-21 Paul Smith <psmith@gnu.org>
821 * configure.in: Don't turn on case-insensitive file system support
822 if --disable-... is given. Fixes Savannah bug #19348.
824 2007-03-19 Paul Smith <psmith@gnu.org>
826 * ALL: Use the strcache for all file name strings, or other
827 strings which we will never free. The goal is to save memory by
828 avoiding duplicate copies of strings. However, at the moment this
829 doesn't save much memory in most situations: due to secondary
830 expansion we actually save prerequisite lists twice (once before
831 the secondary expansion, and then again after it's been parsed
832 into individual file names in the dep list). We will resolve this
833 in a future change, by doing the parsing up-front for targets
834 where secondary expansion is not set.
836 Moving things into the strcache also allows us to use const
837 pointers in many more places.
839 2007-01-03 Paul Smith <psmith@gnu.org>
841 * make.h (ENULLLOOP): Reset errno after each failed invocation of
842 the function, not just the first. Fixes Savannah bug #18680.
844 2006-11-18 Paul Smith <psmith@gnu.org>
846 * strcache.c (strcache_add_len): Don't allocate a new buffer
847 unless the string is not already nil-terminated. Technically this
848 is a violation of the standard, since we may be passed an array
849 that is not long enough to test one past. However, in make this
850 is never true since we only use nil-terminated strings or
853 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
855 * main.c: New global cmd_prefix, defaults to '\t'.
856 * job.c (construct_command_argv_internal): Use cmd_prefix instead
860 (dir_contents_file_exists_p): Check for an error return from
861 readdir(), just in case.
863 * commands.c: Constified.
864 * default.c: Constified.
865 * expand.c: Constified.
866 * function.c: Partial constification.
867 * variable.c: Partial constification.
868 * vmsify.c: Constification. Hard to test this but I hope I didn't

882 2006-10-21 Paul Smith <psmith@gnu.org>
885 * arscan.c: Constified.
887 2006-09-30 Paul Smith <psmith@gnu.org>
889 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
890 point to lastword since the example was updated.
891 Fixes Savannah bug #16304.
892 (Secondary Expansion): Correct example description.
893 Fixes Savannah bug #16468.
894 (Makefile Contents): Clarify that comments cannot appear within
895 variable references or function calls.
896 Fixes Savannah bug #16577.
897 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
898 Fixes Savannah bug #17701.
899 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1086 listed non-existent files as changed. Turns out there's a bug in
1087 the Linux kernel builds which means that this change causes
1088 everything to rebuild every time. We will re-introduce this fix
1089 in the next release, to give them time to fix their build system.
1090 Fixes Savannah bug #16002.
1091 Introduces Savannah bug #16051.
1093 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1094 we *don't* find UNIX "/".
1095 Reported by David Ergo <david.ergo@alterface.com>
1097 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1099 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1100 locator function find_and_set_default_shell if SHELL came from the
1103 2006-02-20 Paul D. Smith <psmith@gnu.org>
1105 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1106 to be null; don't core in that case.
1108 2006-02-19 Paul D. Smith <psmith@gnu.org>
1110 * commands.c (set_file_variables): Realloc, not malloc, the static
1111 string values to avoid memory leaks.
1113 * expand.c (recursively_expand_for_file): Only set reading_file to
1114 an initialized value.
1116 * implicit.c (pattern_search): We need to make a copy of the stem
1117 if we get it from an intermediate dep, since those get freed.
1119 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1121 (enter_file) [VMS]: Ditto.
1122 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1124 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1126 * job.c (construct_command_argv_internal): Fix last change.
1128 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1129 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1130 the calls to _beginthreadex.
1132 * expand.c (recursively_expand_for_file): Initialize `save' to
1133 prevent compiler warnings.
1135 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1137 * job.c (construct_command_argv_internal): Don't create a temporary
1138 script/batch file if we are under -n. Call _setmode to switch the
1139 script file stream to text mode.
1141 2006-02-17 Paul D. Smith <psmith@gnu.org>
1143 * variable.c (merge_variable_set_lists): Don't try to merge the
1144 global_setlist. Not only is this useless, but it can lead to
1145 circularities in the linked list, if global_setlist->next in one
1146 list gets set to point to another list which also ends in
1148 Fixes Savannah bug #15757.
1150 2006-02-15 Paul D. Smith <psmith@gnu.org>
1152 Fix for Savannah bug #106.
1154 * expand.c (expanding_var): Keep track of which variable we're
1155 expanding. If no variable is being expanded, it's the same as
1157 * make.h (expanding_var): Declare it.
1158 * expand.c (recursively_expand_for_file): Set expanding_var to the
1159 current variable we're expanding, unless there's no file info in
1160 it (could happen if it comes from the command line or a default
1161 variable). Restore it before we exit.
1162 * expand.c (variable_expand_string): Use the expanding_var file
1163 info instead of the reading_file info.
1164 * function.c (check_numeric): Ditto.
1166 (func_wordlist): Ditto.
1167 (func_error): Ditto.
1168 (expand_builtin_function): Ditto.
1169 (handle_function): Ditto.
1171 2006-02-14 Paul D. Smith <psmith@gnu.org>
1173 * read.c (eval): Even if the included filenames expands to the
1174 empty string we still need to free the allocated buffer.
1176 * implicit.c (pattern_search): If we allocated a variable set for
1177 an impossible file, free it.
1178 * variable.c (free_variable_set): New function.
1179 * variable.h: Declare it.
1181 * read.c (read_all_makefiles): Makefile names are kept in the
1182 strcache, so there's never any need to alloc/free them.
1185 * main.c (main): Add "archives" to the .FEATURES variable if
1186 archive support is enabled.
1187 * doc/make.texi (Special Variables): Document it.
1189 2006-02-13 Paul D. Smith <psmith@gnu.org>
1191 * implicit.c (pattern_search): Add checking for DOS pathnames to
1192 the pattern rule target LASTSLASH manipulation.
1193 Fixes Savannah bug #11183.

1197 * (ALL FILES): Updated copyright and license notices.
1199 2006-02-10 Paul D. Smith <psmith@gnu.org>
1201 A new internal capability: the string cache is a read-only cache
1202 of strings, with a hash table interface for fast lookup. Nothing
1203 in the cache will ever be freed, so there's no need for reference
1204 counting, etc. This is the beginning of a full solution for
1205 Savannah bug #15182, but for now we only store makefile names here.
1207 * strcache.c: New file. Implement a read-only string cache.
1208 * make.h: Add prototypes for new functions.
1209 * main.c (initialize_global_hash_tables): Initialize the string cache.
1210 (print_data_base): Print string cache stats.
1211 * read.c (eval_makefile): Use the string cache to store makefile
1212 names. Rewrite the string allocation to be sure we free everything.
1214 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1216 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1217 directory time stamp didn't change, except on FAT filesystems.
1218 Suggested by J. David Bryan <jdbryan@acm.org>.
1220 2006-02-09 Paul D. Smith <psmith@gnu.org>
1222 * function.c (func_or): Implement a short-circuiting OR function.
1223 (func_and): Implement a short-circuiting AND function.
1224 (function_table_init): Update the table with the new functions.
1225 * doc/make.texi (Conditional Functions): Changed the "if" section
1226 to one on general conditional functions. Added documentation for
1227 $(and ...) and $(or ...) functions.
1228 * NEWS: Note new $(and ...) and $(or ...) functions.
1230 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1232 * job.h (struct child): Add the dontcare bitfield.
1233 * job.c (new_job): Cache dontcare flag.
1234 * job.c (reap_children): Use cached dontcare flag instead of the
1235 one in struct file. Fixes Savannah bug #15641.
1237 2006-02-06 Paul D. Smith <psmith@gnu.org>
1239 * vpath.c (selective_vpath_search): If the file we find has a
1240 timestamp from -o or -W, use that instead of the real time.
1241 * remake.c (f_mtime): If the mtime is a special token from -o or
1242 -W, don't overwrite it with the real mtime.
1243 Fixes Savannah bug #15341.
1245 Updates from Markus Mauhart <qwe123@chello.at>:
1247 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1248 (process_signal, process_last_err, process_exit_code): Manage
1249 invalid handle values.
1250 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1251 manage invalid handles; remove them.
1252 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1253 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1254 * README.cvs: Updates for building from CVS.
1256 2006-02-05 Paul D. Smith <psmith@gnu.org>
1258 * file.c (enter_file): Keep track of the last double_colon entry,
1259 to avoid walking the list every time we want to add a new one.
1260 Fixes Savannah bug #15533.
1261 * filedef.h (struct file): Add a new LAST pointer.
1263 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1264 the comparison. For 64-bits systems the result of the subtraction
1265 might not fit into an int. Use comparison instead.
1266 Fixes Savannah bug #15534.
1268 * doc/make.texi: Update the chapter on writing commands to reflect
1269 the changes made in 3.81 for backslash/newline and SHELL handling.
1271 2006-02-01 Paul D. Smith <psmith@gnu.org>
1273 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1274 variable st is not used when it's not initialized.

1289 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1291 * remake.c (update_goal_chain): Set g->changed instead of
1292 incrementing it, as it is only 8-bit wide, and could overflow if
1293 many commands got started in update_file.
1295 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1297 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1298 MAXIMUM_WAIT_OBJECTS.
1299 (process_wait_for_any_private): Change dimension of handles[]
1300 array to MAXIMUM_WAIT_OBJECTS.
1301 (process_used_slots): New function.
1302 (process_register): Don't register more processes than the
1303 available number of slots.
1304 (process_easy): Don't start new processes if all slots are used up.
1306 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1307 are already more children than sub_proc.c can handle, behave as if
1308 the load were too high.
1309 (start_job_command): Fix a typo in error message when process_easy
1312 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1314 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1315 the shell is not sh.exe.
1317 * job.c (create_batch_file): Renamed from create_batch_filename;
1318 all callers changed. Don't close the temporary file; return its
1319 file descriptor instead. New arg FD allows to return the file
1321 (construct_command_argv_internal): Use _fdopen instead of fopen to
1322 open the batch file.
1324 2006-01-04 Paul D. Smith <psmith@gnu.org>
1326 * readme.vms: Updates for case-insensitive VMS file systems from
1327 Hartmut Becker <Hartmut.Becker@hp.com>.
1328 * dir.c (vms_hash): Ditto.
1329 * vmsify.c (copyto): Ditto.
1330 * vmsfunctions.c (readdir): Ditto.
1332 * make.1: Add a section on the exit codes for make.
1334 * doc/make.texi: A number of minor updates to the documentation.

1338 * remake.c (update_file_1): Mark a prerequisite changed if it
1341 * read.c (eval): Be sure to strip off trailing whitespace from the
1342 prerequisites list properly. Also, initialize all fields in
1343 struct dep when creating a new one.

1347 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1348 disable warnings for MSC.
1349 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1351 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1353 * doc/make.texi (Execution): Add a footnote about changes in
1354 handling of backslash-newline sequences. Mention the differences
1355 on MS-DOS and MS-Windows.
1357 * NEWS: More details about building the MinGW port and a pointer
1358 to README.W32. Fix the section name that describes the new
1359 backward-incompatible processing of backslash-newline sequences.
1360 The special processing of SHELL set to "cmd" is only relevant to
1361 MS-Windows, not MS-DOS.
1363 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1365 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1366 to DWORD, to avoid compiler warnings.
1367 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1368 use %ld in format, to avoid compiler warnings.
1370 * doc/make.texi (Special Targets): Fix a typo.
1371 (Appending): Fix cross-reference to Setting.
1372 (Special Variables, Secondary Expansion, File Name Functions)
1373 (Flavor Function, Pattern Match, Quick Reference): Ensure two

1382 * read.c (record_target_var): Initialize variable's export field
1383 with v_default instead of leaving it "initialized" by whatever
1384 garbage happened to be on the heap.

1388 * make.1: Fix some display errors and document all existing options.
1389 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1391 2005-12-11 Paul D. Smith <psmith@gnu.org>
1393 * implicit.c (pattern_search): If 2nd expansion is not set for
1394 this implicit rule, replace the pattern with the stem directly,
1395 and don't re-expand the variable list. Along with the other
1396 .SECONDEXPANSION changes below, fixes bug #13781.
1398 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1400 * implicit.c (pattern_search): Mark other files that this rule
1401 builds as targets so that they are not treated as intermediates
1402 by the pattern rule search algorithm. Fixes bug #13022.
1404 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1406 * remake.c (notice_finished_file): Propagate the change of
1407 modification time to all the double-colon entries only if

1426 * read.c (record_files): Don't set deps flags if there are no deps.
1427 * maintMakefile: We only need to build the templates when we are
1428 creating a distribution, so don't do it for "all".
1430 2005-10-24 Paul D. Smith <psmith@gnu.org>
1432 Make secondary expansion optional: its enabled by declaring the
1433 special target .SECONDEXPANSION.
1435 * NEWS: Update information on second expansion capabilities.
1436 * doc/make.texi (Secondary Expansion): Document the
1437 .SECONDEXPANSION special target and its behavior.
1438 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1439 prerequisite list was found in a static pattern rule.
1440 (free_dep_chain): Declare a prototype.
1441 * file.c (parse_prereqs): New function: break out some complexity
1443 (expand_deps): If we aren't doing second expansion, replace % with
1444 the stem for static pattern rules. Call the new function.
1445 * filedef.h (parse_prereqs): Declare a prototype.
1446 * implicit.c (pattern_search): Initialize the new staticpattern
1448 * main.c (second_expansion): Declare a global variable to remember
1449 if the special target has been seen. Initialize the new
1450 staticpattern field for prerequisites.
1451 * make.h: Extern for second_expansion.
1452 * misc.c (free_dep_chain): New function: frees a struct dep list.
1453 * read.c (read_all_makefiles): Initialize the staticpattern field.
1454 (eval_makefile): Ditto.
1455 (record_files): Check for the .SECONDEXPANSION target and set
1456 second_expansion global if it's found.
1457 Use the new free_dep_chain() instead of doing it by hand.
1458 Set the staticpattern field for prereqs of static pattern targets.
1460 2005-10-16 Paul D. Smith <psmith@gnu.org>
1462 * main.c (main): Set CURDIR to be a file variable instead of a
1463 default, so that values of CURDIR inherited from the environment
1464 won't override the make value.
1466 2005-09-26 Paul D. Smith <psmith@gnu.org>
1468 * job.c (construct_command_argv_internal): If the line is empty
1469 remember to free the temporary argv strings.
1472 2005-09-16 Paul D. Smith <psmith@gnu.org>
1474 * job.c (start_job_command): The noerror flag is a boolean (single
1475 bit); set it appropriately.
1476 Reported by Mark Eichin <eichin@metacarta.com>
1478 2005-08-29 Paul D. Smith <psmith@gnu.org>
1480 * function.c (func_error): On Windows, output from $(info ...)
1481 seems to come in the wrong order. Try to force it with fflush().
1483 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1485 * read.c (record_files): Move code that sets stem for static
1486 pattern rules out of the if (!two_colon) condition so it is
1487 also executed for two-colon rules. Fixes Savannah bug #13881.
1489 2005-08-08 Paul D. Smith <psmith@gnu.org>
1491 * make.h: Don't test that __STDC__ is non-0. Some compilers
1492 (Windows for example) set it to 0 to denote "ISO C + extensions".
1495 2005-08-07 Paul D. Smith <psmith@gnu.org>
1497 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1498 conditional (slightly different version of a fix from Eli).
1500 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1501 If make is running in parallel without -k and two jobs die in a
1502 row, but not too close to each other, then make will quit without
1503 waiting for the rest of the jobs to die.
1505 * main.c (die): Don't reset err before calling reap_children() the
1506 second time: we still want it to be in the error condition.
1507 * job.c (reap_children): Use a static variable, rather than err,
1508 to control whether or not the error message should be printed.
1510 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1512 * w32/subproc/sub_proc.c: Include signal.h.
1513 (process_pipe_io, process_file_io): Pass a pointer to a local
1514 DWORD variable to GetExitCodeProcess. If the exit code is
1515 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1517 * job.c [WINDOWS32]: Include windows.h.
1518 (main_thread) [WINDOWS32]: New global variable.
1519 (reap_children) [WINDOWS32]: Get the handle for the main thread
1520 and store it in main_thread.
1522 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1523 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1524 doing anything else. When we are done, close the main thread
1525 handle and exit with status 130.
1527 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1529 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1532 * main.c (find_and_set_default_shell): If found a DOSish shell,
1533 set sh_found and the value of default_shell, and report the
1534 findings in debug mode.
1536 * job.c (construct_command_argv_internal): Check unixy_shell, not
1537 no_default_sh_exe, to decide whether to use Unixy or DOSish
1540 * README.W32: Update with info about the MinGW build.
1542 * build_w32.bat: Support MinGW.
1544 * w32/subproc/build.bat: Likewise.
1546 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1547 printing DWORD args.
1549 * function.c (windows32_openpipe): Fix format strings for printing
1552 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1554 (start_job_command): Fix format string for printing the result of
1556 (start_job_command) [WINDOWS32]: Do not define.
1557 (exec_command): Fix format string for printing HANDLE args.
1559 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1560 to avoid compiler warnings.
1561 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1562 (Note: some of these fixes were submitted independently by J. Grant)
1564 2005-07-30 J. Grant <jg@jguk.org>
1566 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1567 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1568 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1570 2005-07-15 Paul Smith <psmith@gnu.org>
1572 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1573 we don't have a POSIX shell, then revert to the old
1574 backslash-newline behavior (where they are stripped).
1577 2005-07-08 Paul D. Smith <psmith@gnu.org>
1579 * config.h.W32.template: Reorder to match the standard config.h,
1580 for easier comparisons.
1581 From J. Grant <jg@jguk.org>
1583 * maintMakefile: Remove .dep_segment before overwriting it, in
1584 case it's not writable or noclobber is set.
1585 * expand.c (variable_expand_string): Cast result of pointer
1586 arithmetic to avoid a warning.
1587 * main.c (switches): Add full-fledged final initializer.
1589 2005-07-06 Paul D. Smith <psmith@gnu.org>
1591 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1592 * signame.c (strsignal): If we found _sys_siglist[] or
1593 __sys_siglist[] use those instead of sys_siglist[].
1594 From Albert Chin <china@thewrittenword.com>
1596 2005-07-04 Paul D. Smith <psmith@gnu.org>
1598 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1599 globfree(); set up to use the GNU versions.
1600 From Martin Zinser <zinser@zinser.no-ip.info>
1602 2005-07-03 Paul D. Smith <psmith@gnu.org>
1604 From J. Grant <jg@jguk.org>:
1606 * README.W32.template: Update the Windows and tested MSVC versions.
1607 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1608 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1609 * build_w32.bat: Ditto.
1610 * w32/subproc/build.bat: Ditto.
1612 2005-06-28 Paul D. Smith <psmith@gnu.org>
1614 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1615 declaration was checked but not present.
1617 2005-06-27 Paul D. Smith <psmith@gnu.org>
1619 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1620 to unsigned long. Fixes Savannah bug #13550.
1622 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1623 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1624 Fixes Savannah bug #13551.
1626 2005-06-26 Paul D. Smith <psmith@gnu.org>
1628 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1629 it if ANSI_STRING is not set.
1631 2005-06-25 Paul D. Smith <psmith@gnu.org>
1633 * read.c (eval): If no filenames are passed to any of the
1634 "include" variants, don't print an error.
1635 * doc/make.texi (Include): Document this.
1636 Fixes Savannah bug #1761.
1638 * job.c (construct_command_argv_internal): Sanitize handling of
1639 backslash/newline pairs according to POSIX: that is, keep the
1640 backslash-newline in the command script, but remove a following
1641 TAB character, if present. In the fast path, make sure that the
1642 behavior matches what the shell would do both inside and outside
1643 of quotes. In the slow path, quote the backslash and put a
1644 literal newline in the string.
1645 Fixes Savannah bug #1332.
1646 * doc/make.texi (Execution): Document the new behavior and give
1648 * NEWS: Make a note of the new behavior.
1650 * make.h [WINDOWS32]: #include <direct.h>.
1651 Fixes Savannah bug #13478.
1653 * remake.c (name_mtime): If the stat() of a file fails and the -L
1654 option was given and the file is a symlink, take the best mtime of
1655 the symlink we can get as the mtime of the file and don't fail.
1656 Fixes Savannah bug #13280.
1658 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1659 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1660 inside a variable reference. Make this function static as it's
1662 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1663 parsing an unexpanded line looking for semicolons.
1664 Fixes Savannah bug #1454.
1665 * misc.c (remove_comments): Move this to read.c and make it static
1666 as it's only used there. Call find_char_unquote() with new arg.
1667 * make.h: Remove prototypes for find_char_unquote() and
1668 remove_comments() since they're static now.
1670 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1671 its export flag and obtain its value. When we need to re-exec,
1672 increment the value and add it into the environment.
1673 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1674 * NEWS: Mention MAKE_RESTARTS.
1675 * main.c (always_make_set): New variable. Change the -B option to
1676 set this one instead.
1677 (main): When checking makefiles, only set always_make_flag if
1678 always_make_set is set AND the restarts flag is 0. When building
1679 normal targets, set it IFF always_make_set is set.
1680 (main): Avoid infinite recursion with -W, too: only set what-if
1681 files to NEW before we check makefiles if we've never restarted
1682 before. If we have restarted, set what-if files to NEW _after_ we
1684 Fixes Savannah bug #7566:
1686 2005-06-17 Paul D. Smith <psmith@gnu.org>
1688 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1689 in the prerequisites list.
1691 2005-06-12 Paul D. Smith <psmith@gnu.org>
1693 Fix Savannah bug # 1328.
1695 * configure.in: Check for atexit().
1696 * misc.c (close_stdout): Test stdout to see if writes to it have
1697 failed. If so, be sure to exit with a non-0 error code. Based on
1698 code found in gnulib.
1699 * make.h: Prototype.
1700 * main.c (main): Install close_stdout() with atexit().
1702 2005-06-10 Paul D. Smith <psmith@gnu.org>
1704 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1706 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1707 headers; make vmsWaitForChildren() static; extern vmsify().
1708 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1709 Don't create child_execute_job() here (it's in vmsjobs.c).
1710 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1712 2005-06-09 Paul D. Smith <psmith@gnu.org>
1714 * variable.c (push_new_variable_scope): File variables point
1715 directly to the global_setlist variable. So, inserting a new
1716 scope in front of that has no effect on those variables: they
1717 don't go through current_variable_set_list. If we're pushing a
1718 scope and the current scope is global, push it "the other way" so
1719 that the new setlist is in the global_setlist variable, and
1720 next points to a new setlist with the global variable set.
1721 (pop_variable_scope): Properly undo a push with the new
1723 Fixes Savannah bug #11913.
1725 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1727 * job.c (reap_children): Don't die of the command failed but
1728 the dontcare flag is set. Fixes Savannah bug #13216.
1730 * implicit.c (pattern_search): When creating a target from
1731 an implicit rule match, lookup pattern target and set precious
1732 flag in a newly created target. Fixes Savannah bug #13218.
1734 2005-05-13 Paul D. Smith <psmith@gnu.org>
1736 Implement "if... else if... endif" syntax.
1738 * read.c (eval): Push all checks for conditional words ("ifeq",
1739 "else", etc.) down into the conditional_line() function.
1740 (conditional_line): Rework to allow "else if..." clause. New
1741 return value -2 for lines which are not conditionals. The
1742 ignoring flag can now also be 2, which means "already parsed a
1743 true branch". If that value is seen no other branch of this
1744 conditional can be considered true. In the else parsing if there
1745 is extra text after the else, invoke conditional_line()
1746 recursively to see if it's another conditional. If not, it's an
1747 error. If so, raise the conditional value to this level instead
1748 of creating a new conditional nesting level. Special check for
1749 "else" and "endif", which aren't allowed on the "else" line.
1750 * doc/make.texi (Conditional Syntax): Document the new syntax.
1752 2005-05-09 Paul D. Smith <psmith@gnu.org>
1754 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1755 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1756 recurses to the w32 directory, even on non-Windows systems. Use
1757 the method suggested in the automake manual.
1758 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1759 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1761 2005-05-07 Paul D. Smith <psmith@gnu.org>
1763 * main.c (die): If we're dying with a fatal error (not that a
1764 command has failed), write back any leftover tokens before we go.
1766 * job.c (set_child_handler_action_flags): If there are jobs
1767 waiting for the load to go down, set an alarm to go off in 1
1768 second. This allows us to wake up from a potentially long-lasting
1769 read() and start a new job if the load has gone down. Turn it off
1771 (job_noop): Dummy signal handler function.
1772 (new_job): Invoke it with the new semantics.
1774 * docs/make.texi: Document secondary expansion. Various cleanups
1777 2005-05-03 Paul D. Smith <psmith@gnu.org>
1779 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1780 the targets which are to ultimately be made are called "goals";
1781 see the GNU make manual. Also, MAKECMDGOALS, etc.
1783 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1784 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1785 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1787 2005-05-02 Paul D. Smith <psmith@gnu.org>
1789 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1790 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1791 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1792 functions to vmsjobs.c. #include it into jobs.c.
1794 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1795 jobserver tokens. I found that this happens when an exported
1796 recursive variable contains a $(shell ...) function reference: in
1797 this situation we could "forget" to write back a token.
1799 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1800 we have. It's not reliable to depend on the number of children in
1801 our linked list so keep a separate count.
1802 (new_job): Check jobserver_tokens rather than children &&
1803 waiting_jobs. Increment jobserver_tokens when we get one.
1804 (free_child): If jobserver_tokens is 0, internal error. If it's
1805 >1, write a token back to the jobserver pipe (we don't write a
1806 token for the "free" job). Decrement jobserver_tokens.
1808 * main.c: Add variable master_job_slots.
1809 (main): Set it to hold the number of jobs requested if we're the
1810 master process, when using the jobserver.
1811 (die): Sanity checks: first test jobserver_tokens to make sure
1812 this process isn't holding any tokens we didn't write back.
1813 Second, if master_job_slots is set count the tokens left in the
1814 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1816 2005-04-24 Paul D. Smith <psmith@gnu.org>
1818 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1819 with -l# can lose jobserver tokens, because waiting jobs are not
1820 consulted properly when checking for the "free" token.
1822 * job.c (free_child): Count waiting_jobs as having tokens.
1823 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1824 handle jobs waiting for the load to drop.
1826 2005-04-23 Paul D. Smith <psmith@gnu.org>
1828 * main.c (main): Be careful to not core if a variable setting in
1829 the environment doesn't contain an '='. This is illegal but can
1830 happen in broken setups.
1831 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1833 2005-04-12 Paul D. Smith <psmith@gnu.org>
1835 The second expansion feature causes significant slowdown. Timing
1836 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1837 read the makefile before the feature, to 11+s to do the same
1838 operations after the feature. Additionally, memory usage
1839 increased drastically. To fix this I added some intelligence that
1840 avoids the overhead of the second expansion unless it's required.
1842 * dep.h: Add a new boolean field, need_2nd_expansion.
1844 * read.c (eval): When creating the struct dep for the target,
1845 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1846 (record_files): If there's a "%" in a static pattern rule, it gets
1847 converted to "$*" so set need_2nd_expansion to 1.
1849 * file.c (expand_deps): Rework to be more efficient. Only perform
1850 initialize_file_variables(), set_file_variables(), and
1851 variable_expand_for_file() if the need_2nd_expansion is set.
1853 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1854 (pattern_search): Ditto.
1855 * main.c (handle_non_switch_argument): Ditto.
1857 * read.c (read_all_makefiles): Ditto.
1858 (eval_makefile): Ditto.
1860 2005-04-07 Paul D. Smith <psmith@gnu.org>
1862 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1863 * variable.c (sync_Path_environment): Ditto.
1864 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1866 * main.c (main): Define the .FEATURES variable.
1867 * NEWS: Announce .FEATURES.
1868 * doc/make.texi (Special Variables): Document .FEATURES.
1870 * remake.c (check_dep): If a file is .PHONY, update it even if
1871 it's marked intermediate. Fixes Savannah bug #12331.
1873 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1875 * file.c (expand_deps): Factor out the second expansion and
1876 prerequisite line parsing logic from snap_deps().
1878 * file.c (snap_deps): Use expand_deps(). Expand and parse
1879 prerequisites of the .SUFFIXES special target first. Fixes
1880 Savannah bug #12320.
1882 2005-03-13 Paul D. Smith <psmith@gnu.org>
1884 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1887 2005-03-11 Paul D. Smith <psmith@gnu.org>
1889 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1890 available, not undefined (from Earnie Boyd).
1892 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1894 * implicit.c (pattern_search): Mark an intermediate target as
1895 precious if it happened to be a prerequisite of some (other)
1896 target. Fixes Savannah bug #12267.
1898 2005-03-09 Paul D. Smith <psmith@gnu.org>
1900 * read.c (eval_makefile): Add alloca(0).
1901 (eval_buffer): Ditto.
1903 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1905 * main.c (main): Use o_file instead of o_default when defining
1906 the .DEFAULT_TARGET special variable.
1907 * read.c (eval): Use define_variable_global() instead of
1908 define_variable() when setting new value for the .DEFAULT_TARGET
1909 special variable. Fixes Savannah bug #12266.
1911 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1913 * imlicit.c (pattern_search): Mark files for which an implicit
1914 rule has been found as targets. Fixes Savannah bug #12202.
1916 2005-03-04 Paul D. Smith <psmith@gnu.org>
1919 * doc/make.texi (Automatic Variables): Document $|.
1921 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1923 * read.c (record_files): Instead of substituting % with
1924 actual stem value in dependency list replace it with $*.
1925 This fixes stem triple expansion bug.
1927 * implicit.c (pattern_search): Copy stem to a separate
1928 buffer and make it a properly terminated string. Assign
1929 this buffer instead of STEM (which is not terminated) to
1930 f->stem. Instead of substituting % with actual stem value
1931 in dependency list replace it with $*. This fixes stem
1932 triple expansion bug.
1934 2005-03-01 Paul D. Smith <psmith@gnu.org>
1936 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1937 on Windows, as it takes a handle not a pid. Just exit.
1938 Fix from patch #3679, provided by Alessandro Vesely.
1940 * configure.in: Update check for sys_siglist[] from autoconf manual.
1941 * signame.c (strsignal): Update to use the new autoconf macro.
1943 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1945 * read.c (record_files): Add a check for the list of prerequisites
1946 of a static pattern rule being empty. Fixes Savannah bug #12180.
1948 2005-02-28 Paul D. Smith <psmith@gnu.org>
1950 * doc/make.texi (Text Functions): Update docs to allow the end
1951 ordinal for $(wordlist ...) to be 0.
1952 * function.c (func_wordlist): Fail if the start ordinal for
1953 $(wordlist ...) is <1. Matches documentation.
1954 Resolves Savannah support request #103195.
1956 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1957 previously we were stopping when !-q, exactly the opposite. This
1958 has been wrong since version 1.34, in 1994!
1959 (update_file): If we got an error don't break out to run more
1960 double-colon rules: just return immediately.
1961 Fixes Savannah bug #7144.
1963 2005-02-27 Paul D. Smith <psmith@gnu.org>
1965 * misc.c (end_of_token): Make argument const.
1966 * make.h: Update prototype.
1968 * function.c (abspath, func_realpath, func_abspath): Use
1969 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1970 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1971 * read.c (record_files): Ditto.
1972 * variable.c (do_variable_definition): Ditto.
1974 * function.c (func_error): Create a new function $(info ...) that
1975 simply prints the message to stdout with no extras.
1976 (function_table_init): Add new function to the table.
1977 * NEWS: Add $(info ...) reference.
1978 * doc/make.texi (Make Control Functions): Document it.
1980 New feature: if the system supports symbolic links, and the user
1981 provides the -L/--check-symlink-time flag, then use the latest
1982 mtime between the symlink(s) and the target file.
1984 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1985 readlink(). If both are available, define MAKE_SYMLINKS.
1986 * main.c: New variable: check_symlink_flag.
1987 (usage): Add a line for -L/--check-symlink-times to the help string.
1988 (switches): Add -L/--check-symlink-times command line argument.
1989 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1990 print a warning and disable it again.
1991 * make.h: Declare check_symlink_flag.
1992 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1993 if the file is a symlink then check each link in the chain and
1994 choose the NEWEST mtime we find as the mtime for the file. The
1995 newest mtime might be the file itself!
1996 * NEWS: Add information about this new feature.
1997 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1999 Avoid core dumps described in Savannah bug # 12124:
2001 * file.c: New variable snapped_deps remember whether we've run
2003 (snap_deps): Set it.
2004 * filedef.h: Extern it.
2005 * read.c (record_files): Check snapped_deps; if it's set then
2006 we're trying to eval a new target/prerequisite relationship from
2007 within a command script, which we don't support. Fatal.
2009 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2011 Implementation of the .DEFAULT_TARGET special variable.
2013 * read.c (eval): If necessary, update default_target_name when
2015 * read.c (record_files): Update default_target_file if
2016 default_target_name has changed.
2017 * main.c (default_target_name): Define.
2018 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2019 default_target_name is set use default_target_file as a root
2021 * filedef.h (default_target_name): Declare.
2022 * dep.h (free_dep_chain):
2023 * misc.c (free_dep_chain): Change to operate on struct nameseq
2024 and change name to free_ns_chain.
2025 * file.c (snap_deps): Update to use free_ns_chain.
2027 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2029 Implementation of the second expansion in explicit rules,
2030 static pattern rules and implicit rules.
2032 * read.c (eval): Refrain from chopping up rule's dependencies.
2033 Store them in a struct dep as a single dependency line. Remove
2034 the code that implements SySV-style automatic variables.
2036 * read.c (record_files): Adjust the code that handles static
2037 pattern rules to expand all percents instead of only the first
2038 one. Reverse the order in which dependencies are stored so that
2039 when the second expansion reverses them again they appear in
2040 the makefile order (with some exceptions, see comments in
2041 the code). Remove the code that implements SySV-style automatic
2044 * file.c (snap_deps): Implement the second expansion and chopping
2045 of dependency lines for explicit rules.
2047 * implicit.c (struct idep): Define an auxiliary data type to hold
2048 implicit rule's dependencies after stem substitution and
2051 * implicit.c (free_idep_chain): Implement.
2053 * implicit.c (get_next_word): Implement helper function for
2054 parsing implicit rule's dependency lines into words taking
2055 into account variable expansion requests. Used in the stem
2058 * implicit.c (pattern_search): Implement the second expansion
2059 for implicit rules. Also fixes bug #12091.
2061 * commands.h (set_file_variables): Declare.
2062 * commands.c (set_file_variables): Remove static specifier.
2064 * dep.h (free_dep_chain): Declare.
2065 * misc.c (free_dep_chain): Implement.
2067 * variable.h (variable_expand_for_file): Declare.
2068 * expand.c (variable_expand_for_file): Remove static specifier.
2070 * make.h (strip_whitespace): Declare.
2071 * function.c (strip_whitespace): Remove static specifier.
2073 2005-02-26 Paul D. Smith <psmith@gnu.org>
2075 * main.c (main): Check for ferror() when reading makefiles from stdin.
2076 Apparently some shells in Windows don't close pipes properly and
2079 2005-02-24 Jonathan Grant <jg@jguk.org>
2081 * configure.in: Add MinGW configuration options, and extra w32 code
2083 * Makefile.am: Add MinGW configuration options, and extra w32 code
2085 * main.c: Determine correct program string (after last \ without .exe).
2086 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2088 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2089 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2090 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2091 environment support.
2093 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2095 * function.c (func_shell): When initializing error_prefix, check
2096 that reading file name is not null. This fixes long-standing
2097 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2099 2005-02-09 Paul D. Smith <psmith@gnu.org>
2101 * maintMakefile: Update the CVS download URL to simplify them.
2102 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2103 downloading the .texi files from Savannah now.
2105 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2107 * main.c (handle_non_switch_argument): Only add variables to
2108 command_variables if they're not already there: duplicate settings
2109 waste space and can be confusing to read.
2111 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2112 this header is never included by non-WINDOWS32 code, and it
2113 requires <config.h> to define which isn't always included first.
2115 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2116 testing MINGW32 versions.
2118 * main.c (log_working_directory): flush stdout to be sure the WD
2119 change is printed before any stderr messages show up.
2121 2005-02-01 Paul D. Smith <psmith@gnu.org>
2123 * maintMakefile (po_repo): Update the GNU translation site URL.
2125 2004-12-01 Paul D. Smith <psmith@gnu.org>
2127 * main.c (main): Change char* env_shell to struct variable shell_var.
2128 * variable.c (target_environment): Use new shell_var.
2130 2004-11-30 Paul D. Smith <psmith@gnu.org>
2132 * configure.in: The old way we avoided creating build.sh from
2133 build.sh.in before build.sh.in exists doesn't work anymore; we
2134 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2135 the help!). This also keeps automake from complaining.
2136 * Makefile.am (README): Add a dummy target so automake won't
2137 complain that this file doesn't exist when we checkout from CVS.
2138 * maintMakefile (.dep_segment): Rewrite this rule since newer
2139 versions of automake don't provide DEP_FILES.
2141 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2143 Implementation of `realpath' and `abspath' built-in functions.
2145 * configure.in: Check for realpath.
2146 * function.c (abspath): Return an absolute file name that does
2147 not contain any `.' or `..' components, nor repeated `/'.
2148 * function.c (func_abspath): For each name call abspath.
2149 * function.c (func_realpath): For each name call realpath
2150 from libc or delegate to abspath if realpath is not available.
2151 * doc/make.texi (Functions for File Names): Document new functions.
2152 * doc/make.texi (Quick Reference): Ditto.
2154 2004-11-28 Paul D. Smith <psmith@gnu.org>
2156 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2157 arguments. Fixes bug #10252.
2159 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2161 * main.c (main): Set SHELL to v_noexport by default. Remember the
2162 original environment setting of SHELL in the env_shell variable.
2163 * main.h: Export new env_shell variable.
2164 * variable.c (target_environment): If we find a v_noexport
2165 variable for SHELL, add a SHELL variable with the env_shell value.
2166 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2167 * doc/make.texi (Variables/Recursion): Ditto.
2169 2004-11-28 Paul D. Smith <psmith@gnu.org>
2171 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2172 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2173 Patch by Alessandro Vesely.
2175 2004-11-12 Paul D. Smith <psmith@gnu.org>
2177 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2178 the command line if it's inside a string.
2179 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2181 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2183 * function.c (func_lastword): New function: return last word
2184 from the list of words.
2185 * doc/make.texi: Document $(lastword ). Fix broken links in
2186 Quick Reference section.
2188 2004-10-06 Paul D. Smith <psmith@gnu.org>
2190 Apply patch from Alessandro Vesely, provided with bug # 9748.
2191 Fix use of tmpnam() to work with Borland C.
2193 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2194 construction of a temporary filename, and call new function
2195 create_batch_filename().
2196 (create_batch_filename) [WINDOWS32]: New function to create a
2199 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2201 * read.c (record_target_var): Expand simple pattern-specific
2203 * variable.c (initialize_file_variables): Do not expand simple
2204 pattern-specific variable.
2206 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2208 * remake.c (update_file_1): When rebuilding makefiles inherit
2209 dontcare flag from a target that triggered update.
2211 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2213 * variable.c (initialize_file_variables): Mark pattern-specific
2214 variable as a per-target and copy export status.
2216 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2218 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2220 * implicit.c (pattern_search): When considering an implicit rule's
2221 prerequisite check that it is actually a target rather then
2222 just an entry in the file hashtable.
2224 2004-09-21 Paul D. Smith <psmith@gnu.org>
2226 * read.c (readstring): Fix some logic errors in backslash handling.
2227 (eval): Remove some unnecessary processing in buffer handling.
2228 (record_target_var): Assert that parse_variable_definition() succeeded.
2229 Reported by: Markus Mauhart <qwe123@chello.at>.
2231 * misc.c: Removed the sindex() function. All instances of this
2232 function were trivially replaceable by the standard strstr()
2233 function, and that function will always have better (or certainly
2234 no worse) performance than the very simple-minded algorithm
2235 sindex() used. This can matter with complex makefiles.
2236 * make.h: Remove the prototype for sindex().
2237 * function.c (subst_expand): Convert sindex() call to strstr().
2238 This means we no longer need to track the TLEN value so remove that.
2239 (func_findstring): Convert sindex() to strstr().
2240 * commands.c (chop_commands): Convert sindex() calls to strstr().
2241 Suggested by: Markus Mauhart <qwe123@chello.at>.
2243 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2244 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2245 If SHELL is set to CMD.EXE then assume it's batch-mode and
2246 non-unixy. I wrote the code differently from the patch, though,
2247 to make it safer. This also resolves bug #9174.
2249 2004-09-20 Paul D. Smith <psmith@gnu.org>
2251 * expand.c (variable_expand_string): Modify to invoke
2252 patsubst_expand() instead of subst_expand(); the latter didn't
2253 handle suffix patterns correctly.
2254 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2255 was used only from variable_expand_string() and is no longer used
2257 (func_subst): Ditto, on call to subst_expand().
2258 (patsubst_expand): Require the percent pointers to point to the
2259 character after the %, not to the % itself.
2260 * read.c (record_files): New call criteria for patsubst_expand().
2261 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2262 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2264 2004-09-19 Paul D. Smith <psmith@gnu.org>
2266 * function.c (subst_expand): Fix a check in by_word: look for a
2267 previous blank if we're beyond the beginning of the string, not
2268 the beginning of the word.
2269 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2271 2004-05-16 Paul D. Smith <psmith@gnu.org>
2273 * remake.c (update_goal_chain): Change the argument specifying
2274 whether we're rebuilding makefiles to be a global variable,
2275 REBUILDING_MAKEFILES.
2276 (complain): Extract the code that complains about no rules to make
2277 a target into a separate function.
2278 (update_file_1): If we tried to rebuild a file during the makefile
2279 rebuild phase and it was dontcare, then no message was printed.
2280 If we then try to build the same file during the normal build,
2281 print a message this time.
2282 (remake_file): Don't complain about un-remake-able files when
2283 we're rebuilding makefiles.
2285 2004-05-11 Paul D. Smith <psmith@gnu.org>
2287 * job.c (construct_command_argv_internal): OS/2 patches from
2288 Andreas Buening <andreas.buening@nexgo.de>.
2290 2004-05-10 Paul D. Smith <psmith@gnu.org>
2292 * remake.c (update_file): Don't walk the double-colon chain unless
2293 this is a double-colon rule. Fix suggested by Boris Kolpackov
2294 <boris@kolpackov.net>.
2296 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2297 * readme.vms: New section describing OpenVMS support and issues.
2298 * default.c (default_variables): Add support for IA64.
2299 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2300 without some privilege aborts make with the error
2301 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2302 pressing Ctrl+Y and the input device is no terminal. The change
2303 catches this error and just continues.
2305 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2307 2004-04-25 Paul D. Smith <psmith@gnu.org>
2309 * commands.c (set_file_variables): Set $< properly in the face of
2310 order-only prerequisites.
2311 Patch from Boris Kolpackov <boris@kolpackov.net>
2313 2004-04-21 Bob Byrnes <byrnes@curl.com>
2315 * main.c (main): Notice failures to remake makefiles.
2317 2004-03-28 Paul D. Smith <psmith@gnu.org>
2319 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2321 * job.c: No default shell for RISC OS.
2322 (load_too_high): Hard-code the return to 1.
2323 (construct_command_argv_internal): No sh_chars or sh_cmds.
2324 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2326 2004-03-20 Paul D. Smith <psmith@gnu.org>
2328 * variable.c (do_variable_definition): Don't append from the
2329 global set if a previous non-appending target-specific variable
2330 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2333 * expand.c (reference_variable): Don't give up on variables with
2334 no value that have the target-specific append flag set: they might
2335 have a value after all. Reported by Oliver Schmidt
2336 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2337 <nikulin@dx1cmd.inp.nsk.su>.
2339 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2340 refer to absolute pathnames in directories that don't exist: some
2341 portion of the makefile could create those directories before we
2342 match the pattern. Fixes bugs #775 and #108.
2344 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2346 * main.c (main): Free makefile_mtimes if we have any.
2347 * README.W32.template: Update documentation for the current status
2348 of the MS-Windows port.
2349 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2350 environment variable is sometimes already defined which causes the
2352 * main.c (debug_signal_handler): Only define this function if
2353 SIGUSR1 is available.
2355 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2357 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2358 * README.OS2.template: Documentation updates.
2359 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2360 link line for safety.
2361 * maintMakefile (build.sh.in): Remove an extraneous ")".
2362 * job.c (child_execute_job): Close saved FDs.
2363 * job.c (exec_command) [OS/2]: exec_command(): If the command
2364 can't be exec'ed and if the shell is not Unix-sh, then try again
2365 with argv = { "cmd", "/c", ... }. Normally, this code is never
2366 reached for the cmd shell unless the command really doesn't exist.
2367 (construct_command_argv_internal) [OS/2]: The code for cmd
2368 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2369 The CMD builtin commands are case insensitive so use strcasecmp().
2371 2004-03-19 Paul D. Smith <psmith@gnu.org>
2373 * read.c (do_define): Re-order line counter increment so the count
2374 is accurate (we were losing one line per define). Reported by
2375 Dave Yost <Dave@Yost.com>.
2377 2004-03-06 Paul D. Smith <psmith@gnu.org>
2379 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2381 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2382 * misc.c (message,error,fatal): Ditto.
2383 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2384 * config.h.W32.template: Ditto.
2385 * config.h-vms.template: Ditto.
2386 * config.ami.template: Ditto.
2388 2004-03-04 Paul D. Smith <psmith@gnu.org>
2390 * README.template: Add a note about broken /bin/sh on SunOS
2391 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2393 * misc.c (message, error, fatal): Don't use "..." if we're using
2394 varargs. ansi2knr should handle this but it doesn't work: it
2395 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2396 done. On many systems (SunOS for example) va_dcl is a #define.
2397 So, force the use of the non-"..." version on pre-ANSI compilers.
2399 * maintMakefile (sign-dist): Create some rules to help automate
2400 the new GNU ftp upload method.
2402 2004-02-24 Paul D. Smith <psmith@gnu.org>
2404 * config.h.W32.template: Add HAVE_STDARG_H
2405 * config.h-vms.template: Ditto.
2406 * config.ami.template: Ditto.
2408 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2410 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2411 * build_w32.bat: Remove extra "+".
2413 2004-02-23 Paul D. Smith <psmith@gnu.org>
2415 * make.h: Create an UNUSED macro to mark unused parameters.
2416 * (many): Clean up warnings by applying UNUSED, fixing
2417 signed/unsigned incompatibilities, etc.
2419 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2421 * filedef.h: Name the command_state enumeration.
2422 * file.c (set_command_state): Use the enumeration in the function
2425 * configure.in: Explicitly set SET_MAKE to empty, to disable
2426 MAKE=make even when no make already exists. Fix bug #3823.
2428 2004-02-22 Paul D. Smith <psmith@gnu.org>
2430 * maintMakefile: Perl script to clean up all non-CVS files. Use
2431 it on all the subdirectories for the cvs-clean target.
2433 * main.c (decode_switches): Require non-empty strings for all our
2434 string command-line options. Fixes Debian bug # 164165.
2436 * configure.in: Check for stdarg.h and varargs.h.
2437 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2438 for printing messages.
2439 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2444 A number of patches for OS/2 support from Andreas Buening
2445 <andreas.buening@nexgo.de>:
2447 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2448 disable the SIGCHLD handler.
2449 (reap_children) [OS/2]: Remove special handling of job_rfd.
2450 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2451 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2452 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2453 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2454 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2457 2004-02-21 Paul D. Smith <psmith@gnu.org>
2459 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2460 <mail@kristov.de> reports that if process_begin() fails we don't
2461 handle the error condition correctly in all cases.
2462 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2463 to have a newline on the message.
2465 * job.c (construct_command_argv_internal): Add "test" to UNIX
2466 sh_cmds[]. Fixes Savannah bug # 7606.
2468 2004-02-04 Paul D. Smith <psmith@gnu.org>
2470 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2471 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2472 Hartmut Becker <Hartmut.Becker@hp.com>.
2474 2004-01-21 Paul D. Smith <psmith@gnu.org>
2476 * job.c (load_too_high): Implement an algorithm to control the
2477 "thundering herd" problem when using -l to control job creation
2478 via the load average. The system only recomputes the load once a
2479 second but we can start many jobs in a second. To solve this we
2480 keep track of the number of jobs started in the last second and
2481 apply a weight to try to guess what a correct load would be.
2482 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2483 Also fixes bug #4693.
2484 (reap_children): Decrease the job count for this second.
2485 (start_job_command): Increase the job count for this second.
2487 * read.c (conditional_line): Expand the text after ifn?def before
2488 checking to see if it's a single word. Fixes bug #7257.
2490 2004-01-09 Paul D. Smith <psmith@gnu.org>
2492 * file.c (print_file): Recurse to print all targets in
2493 double-colon rules. Fixes bug #4518, reported (with patch) by
2494 Andrew Chatham <chatham@google.com>.
2496 2004-01-07 Paul D. Smith <psmith@gnu.org>
2498 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2499 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2500 AC_FUNC_SETVBUF_REVERSED.
2502 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2503 (MAKE Variable): Fix Savannah bug #4898.
2505 * job.c (construct_command_argv_internal): Add "!" to the list of
2506 shell escape chars. POSIX sh allows it to appear before a
2507 command, to negate the exit code. Fixes bug #6404.
2509 * implicit.c (pattern_search): When matching an implicit rule,
2510 remember which dependencies have the ignore_mtime flag set.
2511 Original fix provided in Savannah patch #2349, by Benoit
2512 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2514 2003-11-22 Paul D. Smith <psmith@gnu.org>
2516 * README.W32.template (Outputs): Clarification on -j with
2517 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2520 2003-11-02 Paul D. Smith <psmith@gnu.org>
2522 * function.c (func_if): Strip all the trailing whitespace from the
2523 condition, then don't expand it. Fixed bug # 5798.
2525 * expand.c (recursively_expand_for_file): If we're expanding a
2526 variable with no file context, then use the variable's context.
2529 2003-10-21 Paul D. Smith <psmith@gnu.org>
2531 * main.c (log_working_directory): Add newlines to printf()s.
2533 * README.cvs: Add a note to ignore warnings during autoreconf.
2535 * maintMakefile (po_repo): Set a new URL for PO file updates.
2536 (get-config/config.guess get-config/config.sub): Get these files
2537 from the Savannah config project instead of ftp.gnu.org.
2539 2003-10-05 Paul Eggert <eggert@twinsun.com>
2541 * main.c (main): Avoid potential subscript error if environ has
2544 2003-08-22 Paul D. Smith <psmith@gnu.org>
2546 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2547 systems which don't yet implement the C89 standard :-/.
2549 2003-07-18 Paul D. Smith <psmith@gnu.org>
2551 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2552 [WINDOWS32]: Initialize hash.
2554 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2556 * dir.c (read_dirstream): Provide a workaround for broken versions of
2557 the MinGW dirent structure.
2559 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2561 * w32/include/dirent.h: Add __MINGW32__ filter.
2563 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2565 * make.h: Add global declaration of *make_host.
2566 * main.c (print_usage): Remove local declaration of *make_host.
2567 (print_version): Display "This program built for ..." after Copyright
2570 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2572 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2573 execution of "makeinfo --html make.texi".
2575 2003-04-30 Paul D. Smith <psmith@gnu.org>
2577 * build.template: Make some changes to maybe allow this script to
2578 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2580 * README.OS2.template: New file for OS/2 support. Original
2581 contributed by Andreas Buening.
2582 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2585 2003-04-19 Paul D. Smith <psmith@gnu.org>
2587 Fix bug #1405: allow a target to match multiple pattern-specific
2590 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2591 variable.c, where they've always belonged.
2592 * rule.h: Move the prototypes and struct pattern_var as well.
2593 * variable.c (initialize_file_variables): Invoke
2594 lookup_pattern_var() in a loop, until no more matches are found.
2595 If a match is found, create a new variable set for the target's
2596 pattern variables. Then merge the contents of each matching
2597 pattern variable set into the target's pattern variable set.
2598 (lookup_pattern_var): Change this function to be usable
2599 in a loop. It takes a starting position: if NULL, start at the
2600 beginning; if non-NULL, start with the pattern variable after that
2601 position, and return the next matching pattern.
2602 (create_pattern_var): Create a unique instance of
2603 pattern-specific variables for every definition in the makefile.
2604 Don't combine the same pattern together. This allows us to
2605 process the variable handling properly even when the same pattern
2606 is used multiple times.
2607 (parse_variable_definition): New function: break out the parsing
2608 of a variable definition line from try_variable_definition.
2609 (try_variable_definition): Call parse_variable_definition to
2611 (print_variable_data_base): Print out pattern-specific variables.
2612 * variable.h (struct variable): Remember when a variable is
2613 conditional. Also remember its flavor.
2614 (struct pattern_var): Instead of keeping a variable set, we just
2615 keep a single variable for each pattern.
2616 * read.c (record_target_var): Each pattern variable contains only a
2617 single variable, not a set, so create it properly.
2618 * doc/make.texi (Pattern-specific): Document the new behavior.
2620 2003-04-17 Paul D. Smith <psmith@gnu.org>
2622 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2623 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2624 file/directory naming rules for VMS so I can't tell whether this
2627 2003-04-09 Paul D. Smith <psmith@gnu.org>
2629 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2630 DOS-style pathnames: backslash separators and drive specifiers.
2632 2003-03-28 Paul D. Smith <psmith@gnu.org>
2634 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2635 the intermediate flag on all targets. Fixes bug #2515.
2637 2003-03-24 Paul D. Smith <psmith@gnu.org>
2639 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2640 Upgrade to autoconf 2.57 and automake 1.7.3.
2642 * job.c: More OS/2 changes from Andreas Buening.
2644 * file.c (print_file): Fix variable initialization.
2647 * remake.c (notice_finished_file):
2649 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2650 some calls (like readdir()) return NULL in valid situations
2651 without resetting errno. Fixes bug #2846.
2653 2003-02-25 Paul D. Smith <psmith@gnu.org>
2655 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2657 * job.c (_is_unixy_shell) [OS/2]: New function.
2658 Set default shell to /bin/sh.
2659 (reap_children): Close the job_rfd pipe here since we don't use a
2661 (set_child_handler_action_flags): define this to empty on OS/2.
2662 (start_job_command): Close the jobserver pipe and use
2663 child_execute_job() instead of fork/exec.
2664 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2665 rather than exec'ing, then reconfigure stdin/stdout.
2666 (exec_command): Rewrite to use spawn instead of exec. Return the
2669 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2670 in DOS. Handle the TEMP environment variable as in DOS. Don't
2671 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2672 use -j in DOS mode. Use child_execute_job() instead of
2675 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2678 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2679 prototypes that return values.
2681 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2683 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2684 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2686 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2689 2003-02-24 Paul D. Smith <psmith@gnu.org>
2691 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2692 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2693 (child_execute_job) [VMS]: Handle error status properly.
2694 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2696 * function.c (func_shell): Use EINTRLOOP() while reading from the
2697 subshell pipe (Fixes bug #2502).
2698 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2700 * main.c (main): Ditto.
2702 2003-01-30 Paul D. Smith <psmith@gnu.org>
2704 * read.c (eval): eval() was not fully reentrant, because the
2705 collapsed buffer was static. Change it to be an automatic
2706 variable so that eval() can be invoked recursively.
2708 (eval): Apply patch # 1022: fix memory reference error on long
2709 target-specific variable lines.
2710 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2712 * function.c (check_numeric): Combine the is_numeric() function
2713 into this function, since it's only called from one place.
2714 Constify this function. Have it print the incorrect string in the
2715 error message. Fixes bug #2407.
2716 (strip_whitespace): Constify.
2717 (func_if): Constify.
2718 * expand.c (expand_argument): Constify.
2720 2003-01-29 Paul D. Smith <psmith@gnu.org>
2722 Fix bug # 2169, also reported by other people on various systems.
2724 * make.h: Some systems, such as Solaris and PTX, do not fully
2725 implement POSIX-compliant SA_RESTART functionality; important
2726 system calls like stat() and readdir() can still fail with EINTR
2727 even if SA_RESTART has been set on the signal handler. So,
2728 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2729 EINTR for system calls which return -1 or 0 (NULL), respectively,
2731 Also, remove the old atomic_stat()/atomic_readdir() and
2732 HAVE_BROKEN_RESTART handling.
2734 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2736 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2737 * remake.c (touch_file): Ditto.
2739 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2740 * read.c (construct_include_path): Ditto.
2741 * remake.c (name_mtime): Ditto.
2742 * vpath.c (selective_vpath_search): Ditto.
2743 * dir.c (find_directory): Ditto.
2744 (local_stat): Ditto.
2745 (find_directory): Use ENULLLOOP() to wrap opendir().
2746 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2748 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2749 atomic_readdir() handling.
2751 2003-01-22 Paul D. Smith <psmith@gnu.org>
2753 * function.c (func_call): Fix Bug #1744. If we're inside a
2754 recursive invocation of $(call ...), mask any of the outer
2755 invocation's arguments that aren't used by this one, so that this
2756 invocation doesn't "inherit" them accidentally.
2758 2002-12-05 Paul D. Smith <psmith@gnu.org>
2760 * function.c (subst_expand): Valery Khamenia reported a
2761 pathological performance hit when doing substitutions on very
2762 large values with lots of words: turns out we were invoking
2763 strlen() a ridiculous number of times. Instead of having each
2764 call to sindex() call strlen() again, keep track of how much of
2765 the text we've seen and pass the length to sindex().
2767 2002-11-19 Paul D. Smith <psmith@gnu.org>
2769 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2772 2002-11-16 Paul D. Smith <psmith@gnu.org>
2774 * NMakefile.template (OBJS): Add hash.c object file.
2775 * SMakefile.template (srcs): Ditto.
2776 * Makefile.ami (objs): Ditto.
2777 * build_w32.bat: Ditto.
2779 * Makefile.DOS.template: Remove extra dependencies.
2781 2002-10-25 Paul D. Smith <psmith@gnu.org>
2783 * expand.c (install_variable_buffer): New function. Install a new
2784 variable_buffer context and return the previous one.
2785 (restore_variable_buffer): New function. Free the current
2786 variable_buffer context and put a previously saved one back.
2787 * variable.h: Prototypes for {install,restore}_variable_buffer.
2788 * function.c (func_eval): Push a new variable_buffer context
2789 before we eval, then restore the old one when we're done.
2792 * read.c (install_conditionals): New function. Install a new
2793 conditional context and return the previous one.
2794 (restore_conditionals): New function. Free the current
2795 conditional context and put a previously saved one back.
2796 (eval): Use the {install,restore}_conditionals for "include"
2798 (eval_buffer): Use {install,restore}_conditionals to preserve the
2799 present conditional state before we evaluate the buffer.
2802 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2804 (Recursion): Add a variable index entry for CURDIR.
2806 * README.cvs: Update to appropriate versions.
2807 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2808 don't need to copy loadavg.c: automake is smart enough to create
2809 it for me. Still have a bug in automake related to ansi2knr tho.
2811 2002-10-14 Paul D. Smith <psmith@gnu.org>
2813 * remake.c (notice_finished_file): Only touch targets if they have
2814 at least one command (as per POSIX). Resolve Bug #1418.
2816 * *.c: Convert to using ANSI C-style function definitions.
2817 * Makefile.am: Enable the ansi2knr feature of automake.
2818 * configure.in: ditto.
2820 2002-10-13 Paul D. Smith <psmith@gnu.org>
2822 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2823 for automatic variable values like $^, etc. In the case of very
2824 large lists of prerequisites this causes problems. Instead reuse
2825 a static buffer (resizeable) for each variable.
2827 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2828 target-specific variable definitions. Check for it and set an
2830 (record_target_var): Set the export field to v_export if the
2831 "exported" flag is set.
2832 * doc/make.texi (Target-specific): Document the ability to use
2835 * doc/make.texi: Change the name of the section on automatic
2836 variables from "Automatic" to "Automatic Variables". Added text
2837 clarifying the scope of automatic variables.
2839 2002-10-04 Paul D. Smith <psmith@gnu.org>
2841 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2843 (record_files): Ditto.
2845 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2846 the search for the '=' to only within the enclosing parens.
2848 2002-10-03 Paul D. Smith <psmith@gnu.org>
2850 Version 3.80 released.
2852 * dir.c: Change hash functions to use K&R function definition style.
2853 * function.c: Ditto.
2855 * variable.c: Ditto.
2857 Update to automake 1.7.
2859 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2860 (pdf): Remove this target as automake now provides one.
2862 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2864 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2866 * makefile.com: Updates for GNU make 3.80.
2867 * makefile.vms: Ditto.
2869 2002-09-23 Paul D. Smith <psmith@gnu.org>
2871 * read.c (enum make_word_type): Remove w_comment.
2872 (get_next_mword): Don't treat comment characters as special; where
2873 this function is used we will never see a comment (it's stripped
2874 before we get here) and treating comments specially means that
2875 targets like "foo\#bar" aren't handled properly.
2877 2002-09-18 Paul D. Smith <psmith@gnu.org>
2879 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2881 * read.c (eval): Expansion of arguments to export/unexport was
2882 ignoring all arguments after the first one. Change the algorithm
2883 to expand the whole line once, then parse the results.
2885 2002-09-17 Paul D. Smith <psmith@gnu.org>
2887 Fix Bug #940 (plus another bug I found while looking at this):
2889 * read.c (record_target_var): enter_file() will add a new entry if
2890 it's a double-colon target: we don't want to do that in this
2891 situation. Invoke lookup_file() and only enter_file() if it does
2892 not already exist. If the file we get back is a double-colon then
2893 add this variable to the "root" double-colon target.
2895 * variable.c (initialize_file_variables): If this file is a
2896 double-colon target but is not the "root" target, then initialize
2897 the root and make the root's variable list the parent of our
2900 2002-09-13 Paul D. Smith <psmith@gnu.org>
2902 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2904 * hash.c (round_up_2): Get rid of a warning.
2906 2002-09-12 Paul D. Smith <psmith@gnu.org>
2908 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2909 so it doesn't complain about getloadavg.c.
2911 * commands.c (set_file_variables): Make sure we always alloca() at
2912 least 1 character for the value of $? (for '\0').
2914 2002-09-11 Paul D. Smith <psmith@gnu.org>
2916 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2917 macro to use RESULT instead of the incorrect _RESULT_.
2919 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2920 and atomic_readdir(). We need to #include dirent.h to get this to
2922 * misc.c (atomic_readdir): Fix typos.
2924 2002-09-10 Paul D. Smith <psmith@gnu.org>
2926 * read.c (eval): Expand variable lists given to export and
2927 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2928 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2930 * doc/make.texi (Variables/Recursion): Document this.
2931 (Conditional Syntax): And here.
2933 2002-09-09 Paul D. Smith <psmith@gnu.org>
2935 * configure.in: Check for memmove().
2937 2002-09-07 Paul D. Smith <psmith@gnu.org>
2939 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2940 Michael Sterrett <msterret@coat.com> reports that while it has
2941 SA_RESTART, it does not work properly.
2943 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2944 that invokes stat() and loops to do it again if it returns EINTR.
2945 (atomic_readdir): Ditto, with readdir().
2947 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2948 and readdir() to atomic_stat() and atomic_readdir().
2950 2002-09-04 Paul D. Smith <psmith@gnu.org>
2952 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2953 reports that GNU make sometimes doesn't recognize that targets can
2954 be made, when directories can be created as prerequisites. He
2955 reports that changing the order of predicates in the DEP->changed
2956 flag test so that lookup_file() is always performed, solves this
2959 2002-08-08 Paul D. Smith <psmith@gnu.org>
2961 * configure.in: Require a newer version of gettext.
2963 * misc.c (perror_with_name): Translate the format string (for
2964 right-to-left language support).
2965 (pfatal_with_name): Ditto.
2967 * main.c: Create a static array of strings to store the usage
2968 text. This is done to facilitate translations.
2969 (struct command_switch): Remove argdesc and description fields.
2970 (switches): Remove values for obsolete fields.
2971 (print_usage): Print each element of the usage array.
2973 * hash.c: Change function definitions to be K&R style.
2975 2002-08-02 Paul D. Smith <psmith@gnu.org>
2977 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2978 this one because it's too hard to get right. We'll look at it for
2980 * main.c (main): Don't create the .TARGETS variable.
2981 * variable.c (handle_special_var): Don't handle .TARGETS.
2983 2002-08-01 Paul D. Smith <psmith@gnu.org>
2985 * main.c (switches): Add a new option, -B (--always-make). If

2988 (always_make_flag): New flag.
2989 * make.h: Extern always_make_flag.
2990 * remake.c (update_file_1): Check always_make_flag; if it's set we
2991 will always rebuild any target we can, even if none of its
2992 prerequisites are newer.
2995 * doc/make.texi (Shell Function): Make it clear that make
2996 variables marked as "export" are not passed to instances of the
2999 Add new introspection variable .VARIABLES and .TARGETS.
3001 * variable.c (handle_special_var): New function. If the variable
3002 reference passed in is "special" (.VARIABLES or .TARGETS),
3003 calculate the new value if necessary. .VARIABLES is handled here:
3004 walk through the hash of defined variables and construct a value
3005 which is a list of the names. .TARGETS is handled by
3006 build_target_list().
3007 (lookup_variable): Invoke handle_special_var().
3008 * file.c (build_target_list): Walk through the hask of known files
3009 and construct a list of the names of all the ones marked as
3011 * main.c (main): Initialize them to empty (and as simple variables).
3012 * doc/make.texi (Special Variables): Document them.
3013 * NEWS: Mention them.
3015 * variable.h (struct variable): Add a new flag "exportable" which
3016 is true if the variable name is valid for export.
3017 * variable.c (define_variable_in_set): Set "exportable" when a new
3018 variable is defined.
3019 (target_environment): Use the "exportable" flag instead of
3020 re-checking the name here... an efficiency improvement.
3022 2002-07-31 Paul D. Smith <psmith@gnu.org>
3024 * config.h-vms.template: Updates to build on VMS. Thanks to
3025 Brian_Benning@aksteel.com for helping verify the build.
3026 * makefile.com: Build the new hash.c file.
3027 * hash.h: Use strcpmi(), not stricmp(), in the
3028 HAVE_CASE_INSENSITIVE_FS case.
3030 2002-07-30 Paul D. Smith <psmith@gnu.org>
3032 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3033 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3034 Reported by <Brian_Benning@aksteel.com>.
3036 2002-07-10 Paul D. Smith <psmith@gnu.org>
3038 * variable.c (pop_variable_scope): Remove variable made unused by
3039 new hash infrastructure.
3040 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3041 comparisons as well as name comparisons.

3043 * file.c (lookup_file): Remove variables made unused by new hash
3045 * dir.c (directory_contents_hash_2): Missing return of hash value.
3046 (dir_contents_file_exists_p): Remove variables made unused by new
3047 hash infrastructure.
3050 Installed Greg McGary's integration of the hash functions from the
3051 GNU id-utils package:
3053 2002-07-10 Greg McGary <greg@mcgary.org>
3055 * scripts/functions/filter-out: Add literals to to the
3056 pattern space in order to add complexity, and trigger
3057 use of an internal hash table. Fix documentation strings.
3058 * scripts/targets/INTERMEDIATE: Reverse order of files
3059 passed to expected `rm' command.
3061 2002-07-10 Greg McGary <greg@mcgary.org>

3124 (function_table_init): Renamed from function_table.
3125 (function_table): Declare as `struct hash_table'.
3126 (FUNCTION_TABLE_ENTRIES): New constant.
3127 (hash_init_function_table): New function.
3129 * read.c (hash.h): New #include.
3130 (read_makefile): Pass char constants to find_char_unquote.
3131 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
3132 (uniquize_deps): Use hash table to efficiently identify duplicates.
3133 (find_char_unquote): Accept two char-constant stop chars, rather
3134 than a string constant, avoiding zillions of calls to strchr.
3135 Tighten inner search loops to test only for desired delimiters.
3137 * variable.c (variable_hash_1, variable_hash_2,
3138 variable_hash_cmp): New functions.
3139 (variable_table): Declare as `struct hash_table'.
3140 (global_variable_set): Remove initialization.
3141 (init_hash_global_variable_set): New function.
3142 (define_variable_in_set): Use new hash table package.
3143 (lookup_variable): Likewise.
3144 (lookup_variable_in_set): Likewise.
3145 (initialize_file_variables): Likewise.
3146 (pop_variable_scope): Likewise.
3147 (create_new_variable_set): Likewise.
3148 (merge_variable_sets): Likewise.
3149 (define_automatic_variables): Likewise.
3150 (target_environment): Likewise.
3151 (print_variable_set): Likewise.
3153 2002-07-10 Paul D. Smith <psmith@gnu.org>
3155 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3156 prerequisite list. A real SysV make will expand the entire
3157 prerequisites list _twice_: we don't do that as it's a big
3158 backward-compatibility problem. We only replace those specific
3161 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3162 references left in the list of prerequisites. Check for .POSIX as
3163 we record targets, so we can disable non-POSIX behavior while
3164 reading makefiles as well as running them.
3165 (eval): Check the prerequisite list to see if we have anything
3166 that looks like a SysV prerequisite variable reference.
3168 2002-07-09 Paul D. Smith <psmith@gnu.org>
3170 * doc/make.texi (Prerequisite Types): Add a new section describing
3171 order-only prerequisites.
3173 * read.c (uniquize_deps): If we have the same file as both a
3174 normal and order-only prereq, get rid of the order-only prereq,
3175 since the normal one supersedes it.
3177 2002-07-08 Paul D. Smith <psmith@gnu.org>
3179 * AUTHORS: Added Greg McGary to the AUTHORS file.
3180 * NEWS: Blurbed order-only prerequisites.
3181 * file.c (print_file): Show order-only deps properly when printing
3184 * maintMakefile: Add "update" targets for wget'ing the latest
3185 versions of various external files. Taken from Makefile.maint in
3188 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3189 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3191 2002-07-07 Paul D. Smith <psmith@gnu.org>
3193 * po/*.po: Remove. We'll use wget to retrieve them at release
3196 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3197 rather than a shell you get an exception. Make sure we look up
3198 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3200 * remake.c (notice_finished_file): Fix handling of -t flag.
3201 Patch provided by Henning Makholm <henning@makholm.net>.
3203 * implicit.c (pattern_search): Some systems apparently run short
3204 of stack space, and using alloca() in this function caused an
3205 overrun. I modified it to use xmalloc() on the two variables
3206 which seemed like they might get large. Fixes Bug #476.
3208 * main.c (print_version): Update copyright notice to conform with
3210 (print_usage): Update help output.
3212 * function.c (func_eval): Create a new make function, $(eval
3213 ...). Expand the arguments, put them into a buffer, then invoke
3214 eval_buffer() on the resulting string.
3215 (func_quote): Create a new function, $(quote VARNAME). Inserts
3216 the value of the variable VARNAME without expanding it any
3219 * read.c (struct ebuffer): Change the linebuffer structure to an
3220 "eval buffer", which can be either a file or a buffer.
3221 (eval_makefile): Move the code in the old read_makefile() which
3222 located a makefile into here: create a struct ebuffer with that
3223 information. Have it invoke the new function eval() with that
3225 (eval_buffer): Create a new function that creates a struct ebuffer
3226 that holds a string buffer instead of a file. Have it invoke
3227 eval() with that ebuffer.
3228 (eval): New function that contains the guts of the old
3229 read_makefile() function: this function parses makefiles. Obtains
3230 data to parse from the provided ebuffer. Some modifications to
3231 make the flow of the function cleaner and clearer. Still could
3232 use some work here...
3233 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3234 contents of the define/endef variable from the ebuffer.
3235 (readstring): Read the next line from a string-style ebuffer.
3236 (readline): Read the next line from an ebuffer. If it's a string
3237 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3240 * dep.h (eval_buffer): Prototype eval_buffer();
3242 * variable.c (do_variable_definition): Make sure that all
3243 non-target-specific variables are registered in the global set.
3244 If we're invoked from an $(eval ...) we might be inside a $(call
3245 ...) or other function which has pushed a variable scope; we still
3246 want to define our variables from evaluated makefile code in the
3249 2002-07-03 Greg McGary <greg@mcgary.org>
3251 * dep.h (struct dep) [ignore_mtime]: New member.
3252 [changed]: convert to a bitfield.
3253 * implicit.c (pattern_search): Zero ignore_mtime.
3254 * main.c (main, handle_non_switch_argument): Likewise.
3255 * rule.c (convert_suffix_rule): Likewise.
3256 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3257 (read_makefile): Parse '|' in prerequisite list.
3258 (uniquize_deps): Consider ignore_mtime when comparing deps.
3259 * remake.c (update_file_1, check_dep): Don't force remake for
3260 dependencies that have d->ignore_mtime.
3261 * commands.c (FILE_LIST_SEPARATOR): New constant.
3262 (set_file_variables): Don't include a
3263 prerequisite in $+, $^ or $? if d->ignore_mtime.
3266 2002-06-18 Paul D. Smith <psmith@gnu.org>
3268 * make.texinfo: Updates for next revision. New date/rev/etc.
3269 Recreate all Info menus. Change license on the manual to the GNU
3270 Free Documentation License. A number of typos.
3271 (Variables Simplify): Don't use "-" before it's defined.
3272 (Automatic Prerequisites): Rewrite the target example to work
3273 properly if the compile fails. Remove incorrect comments about
3274 how "set -e" behaves.
3275 (Text Functions): Move the "word", "wordlist", "words", and
3276 "firstword" functions here, from "File Name Functions".
3277 * make-stds.texi: Update from latest GNU version.
3278 * fdl.texi: (created) Import the latest GNU version.
3280 2002-06-06 Paul D. Smith <psmith@gnu.org>
3282 * variable.c (do_variable_definition): New function: extract the
3283 part of try_variable_definition() that actually sets the value
3284 into a separate function.
3285 (try_variable_definition): Call do_variable_definition() after
3286 parsing the variable definition string.
3287 (define_variable_in_set): Make the name argument const.
3289 * variable.h (enum variable_flavor): Make public.
3290 (do_variable_definition): Create prototype.
3292 * read.c (read_all_makefiles): Create a new built-in variable,
3294 (read_makefile): Add each makefile read in to this variable value.
3296 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3298 * Makefile.DOS.template: Tweak according to changes in the
3299 distribution. Add back the dependencies of *.o files.
3301 * configh.dos.template: Synchronize with config.h.in.
3303 2002-05-09 Paul D. Smith <psmith@gnu.org>
3305 * file.c (file_timestamp_now): Use K&R function declaration.
3307 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3308 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3309 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3310 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3311 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3312 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3313 nlist.n_name is a pointer rather than an array.
3315 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3316 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3317 * configure.in: Use it instead of the old version.
3319 * main.c (main): Prefer setvbuf() to setlinebuf().
3321 2002-05-08 Paul D. Smith <psmith@gnu.org>
3323 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3324 (loadavg_LDADD): Ditto.
3326 2002-04-29 Paul D. Smith <psmith@gnu.org>
3328 * expand.c (recursively_expand_for_file): Rename
3329 recursively_expand() to recursively_expand_for_file() and provide
3330 an extra argument, struct file. If the argument is provided, set
3331 the variable scope to that of the file before expanding.
3332 * variable.h (recursively_expand): Make this a macro that invokes
3333 recursively_expand_for_file() with a NULL file pointer.
3334 * variable.c (target_environment): Call the renamed function and
3335 provide the current file context.
3336 Fixes Debian bug #144306.
3338 2002-04-28 Paul D. Smith <psmith@gnu.org>
3340 Allow $(call ...) user-defined variables to be self-referencing
3341 without throwing an error. Allows implementation of transitive
3342 closures, among other possibly useful things.
3343 Requested by: Philip Guenther <guenther@sendmail.com>
3345 * variable.h (struct variable): Add a new field: exp_count, and
3346 new macros to hold its size and maximum value.
3347 (warn_undefined): Make this a macro.
3348 * variable.c (define_variable_in_set): Initialize it.
3349 * expand.c (recursively_expand): If we detect recursive expansion
3350 of a variable, check the exp_count field. If it's greater than 0
3351 allow the recursion and decrement the count.
3352 (warn_undefined): Remove this (now a macro in variable.h).
3353 * function.c (func_call): Before we expand the user-defined
3354 function, modify its exp_count field to contain the maximum
3355 number of recursive calls we'll allow. After the call, reset it
3358 2002-04-21 Paul D. Smith <psmith@gnu.org>
3360 Modified to use latest autoconf (2.53), automake (1.6.1), and
3361 gettext (0.11.1). We're using gettext's new "external" support,
3362 to avoid including libintl source with GNU make.
3364 * README.cvs: New file. Explain how to build GNU make from CVS.
3366 * configure.in: Modify checking for the system glob library.
3367 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3368 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3369 etc. will manage it correctly). Set an automake conditional
3370 USE_LOCAL_GLOB to decide whether to compile the glob library.
3372 * getloadavg.c (main): Include make.h in the "TEST" program to
3375 * Makefile.am: Remove special rules for loadavg. Replace them
3376 with Automake capabilities for building extra programs.
3378 * signame.c: This file does nothing if the system provide
3379 strsignal(). If not, it implements strsignal(). If the system
3380 doesn't define sys_siglist, then we make our own; otherwise we use
3382 * signame.h: Removed.
3384 * main.c (main): No need to invoke signame_init(). Update copyright.
3386 * ABOUT-NLS: Removed.
3387 * gettext.c: Removed.
3388 * gettext.h: Get a simplified copy from the gettext package.
3390 * i18n/*.po: Moved to po/.
3393 * config/*: Created. Contains package configuration helper files.
3394 * config.guess, config.sub: Moved to config directory.
3396 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3397 Rework to use new-style autoconf features. Use the "external"
3398 mode for gettext. Make the build.sh config file conditional on
3399 whether build.sh.in exists, to avoid autoconf errors.
3400 * acinclude.m4: Removed almost all macros as being obsolete.
3401 Rewrote remaining macros to use AC_DEFINE.
3402 * acconfig.h: Removed.
3404 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3405 conditional to handle customs support. Remove special handling
3408 2002-04-20 Paul D. Smith <psmith@gnu.org>
3410 * function.c (func_call): Don't mark the argument variables $1,
3411 etc. as recursive. They've already been fully expanded so
3412 there's no need to do it again, and doing so strips escaped $'s.
3413 Reported by Sebastian Glita <glseba@yahoo.com>.
3415 * remake.c (notice_finished_file): Walk through double-colon
3416 entries via the prev field, not the next field!
3417 Reported by Greg McGary <greg@mcgary.org>.
3419 * main.c (main): If the user specifies -q and asks for a specific
3420 target which is a makefile, we got an assert. In that case it
3421 turns out we should continue normally instead.
3423 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3425 * i18n/he.po: Installed a new translation.
3427 2002-01-07 Paul D. Smith <psmith@gnu.org>
3429 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3431 2001-12-04 Paul D. Smith <psmith@gnu.org>
3433 * i18n/ja.po: Installed an updated translation.
3435 2001-09-06 Paul Eggert <eggert@twinsun.com>
3437 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3438 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3440 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3442 (main): Get rid of any avoidable limit on stack size.
3444 2001-09-04 Paul D. Smith <psmith@gnu.org>
3446 * i18n/da.po: Installed an updated translation.
3448 2001-08-03 Paul D. Smith <psmith@gnu.org>
3450 * i18n/fr.po: Installed an updated translation.
3451 Resolves Debian bug #106720.
3453 2001-06-13 Paul D. Smith <psmith@gnu.org>
3455 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3458 2001-06-11 Paul D. Smith <psmith@gnu.org>
3460 * i18n/ko.po: Installed a new translation.
3462 2001-05-06 Paul D. Smith <psmith@gnu.org>
3464 Modify the EINTR handling.
3466 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3467 the way in which we manage the file descriptor/signal handler race
3468 trap to be more efficient.
3470 2001-05-06 Paul Eggert <eggert@twinsun.com>
3472 Restart almost all system calls that are interrupted, instead
3473 of worrying about EINTR. The lone exception is the read() for
3476 * configure.in (HAVE_SA_RESTART): New macro.
3477 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3478 * main.c (main): Use SA_RESTART instead of the old,
3479 nonstandard SA_INTERRUPT.
3481 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3482 * main.c (bsd_signal): New function or macro,
3483 if the implementation doesn't supply it.
3484 (The bsd_signal function will be in POSIX 1003.1-200x.)
3485 (HANDLESIG): Remove.
3486 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3488 * make.h (EINTR_SET): Remove.
3489 (SA_RESTART): New macro.
3491 * arscan.c (ar_member_touch): Don't worry about EINTR.
3492 * function.c (func_shell): Likewise.
3493 * job.c (reap_children, free_child, new_job): Likewise.
3494 * main.c (main): Likewise.
3495 * remake.c (touch_file, name_mtime): Likewise.
3497 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3498 if fstat failed with errno!=EINTR, the error was ignored.
3500 * job.c (set_child_handler_action_flags): New function.
3501 (new_job): Use it to temporarily clear the SIGCHLD action flags
3502 while reading the token.
3504 2001-05-02 Paul D. Smith <psmith@gnu.org>
3506 * job.c (start_job_command): Don't add define/endef per-line flags
3507 to the top-level flags setting.
3509 2001-04-03 Paul D. Smith <psmith@gnu.org>
3511 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3512 bit on error, so check for odd return values, not non-0 return
3514 (VMS_get_member_info): Calculate the timezone differences correctly.
3515 Reported by John Fowler <jfowler@nyx.net>.
3518 2001-03-14 Paul D. Smith <psmith@gnu.org>
3520 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3521 value before invoking define_variable().
3522 Reported by John Fowler <jfowler@nyx.net>.
3524 2001-02-07 Paul D. Smith <psmith@gnu.org>
3526 * read.c (record_target_var): If we reset the variable due to a
3527 command-line variable setting overriding it, turn off the "append"
3530 2001-01-17 Paul D. Smith <psmith@gnu.org>
3532 * variable.c (lookup_variable) [VMS]: When getting values from the
3533 environment, allocate enough space for the _value_ plus escapes,
3534 not enough space for the name plus escapes :-/.
3535 Reported by John Fowler <jfowler@nyx.net>.
3537 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3538 warnings that make generates, so it doesn't look like an error.
3539 Reported by Karl Berry <karl@gnu.org>.
3542 Fix for PR/2020: Rework appended target-specific variables. I'm
3543 fairly confident this algorithm is finally correct.
3545 * expand.c (allocated_variable_append): Rewrite. Instead of
3546 expanding each appended variable then adding all the expanded
3547 strings together, we append all the unexpanded values going up
3548 through the variable set contexts, then expand the final result.
3549 This behaves just like non-target-specific appended variable
3550 values, while the old way didn't in various corner cases.
3551 (variable_append): New function: recursively append the unexpanded
3552 value of a variable, walking from the outermost variable scope to
3554 * variable.c (lookup_variable): Remove the code that looked up the
3555 variable set list if the found variable was "append". We don't
3557 (lookup_variable_in_set): Make this non-static so we can use it
3559 (try_variable_definition): Use lookup_variable_in_set() rather
3560 than faking out current_variable_set_list by hand (cleanup).
3561 * variable.h: Add a prototype for the now non-static
3562 lookup_variable_in_set().
3564 2000-11-17 Paul D. Smith <psmith@gnu.org>
3566 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3567 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3568 before throwing a fit.
3570 2000-11-17 Paul D. Smith <psmith@gnu.org>
3572 * read.c (readline): CRLF calculations had a hole, if you hit the
3573 buffer grow scenario just right. Reworked the algorithm to avoid
3574 the need for len or lastlen at all. Problem description with
3575 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3577 2000-10-24 Paul D. Smith <psmith@gnu.org>
3579 * gettext.c (SWAP): Declare this with the prototype, otherwise
3580 some systems don't work (non-32-bit? Reported for Cray T3E).
3581 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3583 2000-10-05 Paul D. Smith <psmith@gnu.org>
3585 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3586 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3588 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3590 2000-09-22 Paul D. Smith <psmith@gnu.org>
3592 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3593 parts of the real gettext.h here, and we expect to really include
3594 the real gettext.h later. If we keep this #define, it's ignored.
3596 2000-09-21 Paul D. Smith <psmith@gnu.org>
3598 * main.c (log_working_directory): Rework the text to use complete
3599 sentences, to make life simpler for the translators.
3601 2000-08-29 Paul D. Smith <psmith@gnu.org>
3603 * file.c (remove_intermediates): Print a debug message before we
3604 remove intermediate files, so the user (if she uses -d) knows
3607 2000-08-21 Paul D. Smith <psmith@gnu.org>
3609 * variable.c (try_variable_definition): Change how we handle
3610 target-specific append variable defns: instead of just setting the
3611 value, expand it as an append _but_ only within the current
3612 target's context. Otherwise we lose all but the last value if the
3613 variable is appended more than once within the current target
3614 context. Fixes PR/1831.
3616 2000-08-16 Paul D. Smith <psmith@gnu.org>
3618 * function.c (func_shell): Nul-terminate the buffer before
3619 printing an exec error message (just in case it's not!).
3620 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3622 2000-07-25 Paul D. Smith <psmith@gnu.org>
3624 * job.c (construct_command_argv_internal): Add "~" to the list of
3625 sh_chars[] which disallow optimizing out the shell call.
3627 2000-07-23 Paul Eggert <eggert@twinsun.com>
3629 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3630 supersedes --disable-nsec-timestamps.
3631 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3632 * README: Remove --disable-nsec-timestamps.
3634 * filedef.h (struct file.low_resolution_time): New member.
3635 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3636 * remake.c (update_file_1):
3637 Avoid spurious rebuilds due to low resolution time stamps,
3638 generalizing the earlier code that applied only to archive members.
3639 (f_mtime): Archive members always have low resolution time stamps.
3641 * configure.in: Remove --disable-nsec-timestamps, as this has
3642 been superseded by .LOW_RESOLUTION_TIME.
3644 2000-07-23 Paul Eggert <eggert@twinsun.com>
3646 * configure.in (enable_nsec_timestamps): Renamed from
3647 make_cv_nsec_timestamps, since enable/disable options
3648 shouldn't be cached.
3650 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3651 and Paul Eggert <eggert@twinsun.com>
3653 * file.c (file_timestamp_now):
3654 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3655 so that clock_gettime is not linked unless needed.
3657 * filedef.h (FILE_TIMESTAMP_HI_RES):
3658 Remove definition; "configure" now does this.
3660 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3661 to before high resolution file timestamp check,
3662 since that check now uses uintmax_t.
3663 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3664 high resolution file timestamps.
3665 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3666 so that we don't link in clock_gettime unnecessarily.
3668 2000-07-17 Paul D. Smith <psmith@gnu.org>
3670 * i18n/ja.po: New version of the translation file.
3672 2000-07-07 Paul D. Smith <psmith@gnu.org>
3674 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3675 the offset calculation.
3676 (name_mtime): Replace EINTR test with EINTR_SET macro.
3678 2000-07-07 Paul Eggert <eggert@twinsun.com>
3682 * remake.c (update_file_1):
3683 Avoid spurious rebuilds of archive members due to their
3684 timestamp resolution being only one second.
3685 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3686 the clock's resolution being lower than file timestamps'.
3687 When warning about future timestamps, report only the discrepancy,
3688 not the absolute value of the timestamp and the current time.
3690 * file.c (file_timestamp_now): New arg RESOLUTION.
3691 * filedef.h (file_timestamp_now): Likewise.
3692 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3694 2000-07-05 Paul D. Smith <psmith@gnu.org>
3696 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3697 to listp. Fixes PR/1793.
3699 2000-06-26 Paul Eggert <eggert@twinsun.com>
3701 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3703 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3705 * remake.c (f_mtime): Remove unused var memtime.
3707 2000-06-25 Martin Buchholz <martin@xemacs.org>
3709 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3710 Ran spell-check on make.texinfo.
3712 2000-06-23 Paul D. Smith <psmith@gnu.org>
3714 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3715 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3716 * make.h: Define these macros.
3718 * Version 3.79.1 released.
3720 * configure.in: Add a new option, --disable-nsec-timestamps, to
3721 avoid using sub-second timestamps on systems that support it. It
3722 can lead to problems, e.g. if your makefile relies on "cp -p".
3723 * README.template: Document the issue with "cp -p".
3725 * config.guess, config.sub: Updated.
