1 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
3 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
4 inside the loop that looks up environment for PATH.
6 2009-08-31 Eli Zaretskii <eliz@gnu.org>
8 * function.c (windows32_openpipe): Update envp after calling
11 2009-08-02 Paul Smith <psmith@gnu.org>
13 * remake.c (notice_finished_file): Ensure file->cmds is not null
14 before looping through them. Fixes Savannah bug #21824.
16 * doc/make.texi (Wildcard Examples): Clarify when objects is
17 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
18 (Include): Clarify the behavior of -include.
19 Fixes Savannah bug #18963.
21 2009-08-01 Paul Smith <psmith@gnu.org>
23 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
24 etc. come on the command line. Fixes Savannah bug #27093.
26 * expand.c (expand_argument): If the argument is large enough use
27 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
29 * variable.c (do_variable_definition): Avoid using alloca() to
30 hold values, which can be large. Fixes Savannah bug #23960.
32 * job.c (new_job): Use memmove() instead of strcpy() since both
33 pointers are in the same memory block. Fixes Savannah bug #27148.
34 Patch by Petr Machata.
36 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
38 * job.c (construct_command_argv_internal): Add "ulimit" and
39 "unset" to the sh_cmds for Unixy shells.
41 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
43 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
44 that set make_cv_sys_gnu_glob, so they are also correctly set
45 when the cache has been populated before.
47 2009-07-04 Eli Zaretskii <eliz@gnu.org>
49 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
50 exist, as realpath(3) does where it's supported.
52 2006-07-04 Eli Zaretskii <eliz@gnu.org>
54 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
55 (abspath): Support systems that define HAVE_DOS_PATHS (have
56 drive letters in their file names). Use IS_PATHSEP instead of a
57 literal '/' comparison. Fixes Savannah bug #26886.
59 2009-06-14 Paul Smith <psmith@gnu.org>
61 * remake.c (update_file_1): Remember the original file we marked
62 as updating, so we can clear that flag again. If we find a target
63 via vpath, FILE might change.
64 (check_dep): Ditto. Fixes Savannah bug #13529.
65 Patch by Reid Madsen <reid.madsen@tek.com>.
67 2009-06-13 Paul Smith <psmith@gnu.org>
69 * doc/make.texi (MAKEFILES Variable): Be explicit that files
70 included by MAKEFILES cannot give default goals.
71 * read.c (eval): If set_default is not set, pass the no-default-goal
72 value when we read included makefiles. Fixes Savannah bug #13401.
74 * ar.c (ar_name): Ensure that targets with empty parens aren't
75 considered archive member references: archive members must have a
76 non-empty "member" string. Fixes Savannah bug #18435.
78 * function.c (string_glob): Rely on multi_glob() to determine
79 whether files exist or not. Remove call to file_exists_p() which
80 is not always correct. Fixes Savannah bug #21231.
81 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
82 then only files that really exist will be returned.
83 * dep.h: Add new argument to multi_glob().
84 * rule.c (install_pattern_rule): Ditto.
85 * read.c (eval): Ditto.
86 * main.c (main): Ditto.
87 * implicit.c (pattern_search): Ditto.
88 * file.c (parse_prereqs): Ditto.
89 * default.c (set_default_suffixes): Ditto.
91 2009-06-09 Paul Smith <psmith@gnu.org>
93 * commands.c (set_file_variables): If always_make_flag is set,
94 always add the prereq to $?. Fixes Savannah bug #17825.
96 * remake.c (update_file_1): When rebuilding deps of FILE, also try
97 to rebuild the deps of all the also_make targets for that file.
98 Fixes Savannah bug #19108.
100 * implicit.c (pattern_search): Undo test for is_target, added by
101 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
102 Rule Search Algorithm". Fixes Savannah bug #17752.
104 * main.c (clean_jobserver): Clear the jobserver_fds options and
105 set job_slots to the default when we clean up.
106 (define_makeflags): Return the new MAKEFLAGS value.
107 (main): Reset MAKEFLAGS in the environment when we re-exec.
108 Fixes Savannah bug #18124.
110 2009-06-08 Paul Smith <psmith@gnu.org>
112 * read.c (eval): Collapse continuations post-semicolon on target-
113 specific variables. Fixes Savannah bug #17521.
115 2009-06-07 Paul Smith <psmith@gnu.org>
117 * job.c (reap_children): For older systems without waitpid() (are
118 there any of these left?) run wait(2) inside EINTRLOOP to handle
119 EINTR errors. Fixes Savannah bug #16401.
121 * (various): Debug message cleanup. Fixes Savannah bug #16469.
123 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
125 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
126 not the end, to catch second expansion $(eval ...) defining new
127 target/prereq relationships during snap_deps.
128 Fixes Savannah bug #24622.
130 * read.c (record_files): The second-expansion "f->updating" hack
131 was not completely correct: if assumed that the target with
132 commands always had prerequisites; if one didn't then the ordering
133 was messed up. Fixed for now to use f->updating to decide whether
134 to preserve the last element in the deps list... but this whole
135 area of constructing and reversing the deps list is too confusing
136 and needs to be reworked. Fixes Savannah bug #21198.
138 2009-06-06 Paul Smith <psmith@gnu.org>
140 * hash.c (hash_insert): Remove useless test for NULL.
141 Fixes Savannah bug #21823.
143 * make.h: Move SET_STACK_SIZE determination to make.h.
144 * main.c (main): New global variable, STACK_LIMIT, holds the
145 original stack limit when make was started.
146 * job.c (start_job_command): Reset the stack limit, if we changed it.
147 Fixes Savannah bug #22010.
149 * remake.c (check_dep): Only set the target's state to not-started
150 if it's not already running. Found this while testing -j10 builds
151 of glibc: various targets were being rebuilt multiple times.
152 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
155 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
156 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
159 2009-06-04 Paul Smith <psmith@gnu.org>
161 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
163 * maintMakefile: Modify access of config and gnulib Savannah
164 modules to use GIT instead of CVS.
166 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
167 Fixes Savannah bug #24655.
169 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
170 this can happen during some invocations of $(eval ...) for example.
171 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
173 2009-06-02 Paul Smith <psmith@gnu.org>
175 * configure.in: Check for fileno()
176 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
177 for the makefile file so invocations of $(shell ...) don't inherit it.
178 Fixes Savannah bug #24277.
180 2009-06-01 Paul Smith <psmith@gnu.org>
182 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
183 expansion was handled incorrectly. Rework the default goal
184 handling to save the variable only. Remove default_goal_file and
186 * read.c (eval): Check default_goal_var, not default_goal_name.
187 * read.c (record_target_var): Don't check default_goal_file here.
189 2009-05-31 Paul Smith <psmith@gnu.org>
191 * main.c (main): Expand the .DEFAULT_GOAL variable before using
192 it, and if the multi_glob() returns nothing (say it expanded to
193 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
195 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
196 $(and ..) to the reference. Fixes Savannah bug #25694.
198 * make.1: Be clear that some recipes will be executed even with -n.
199 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
201 * doc/make.texi (Override Directive): Make more clear how
202 overrides and appends interact.
203 Elucidates part of Savannah bug #26207.
205 * read.c (record_target_var): Don't reset the origin on
206 target-specific variables; try_variable_definition() will handle
207 this correctly. Fixes Savannah bug #26207.
209 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
210 Fixes Savannah bug #25712.
212 * implicit.c (pattern_search): Keep a pointer to the beginning of
213 the filename and save that instead of the constructed pointer.
214 Fixes Savannah bug #26593.
215 Patch by Mark Seaborn <mrs@mythic-beasts.com>
217 2009-05-30 Paul Smith <psmith@gnu.org>
219 * doc/make.texi (Multi-Line): Add a description of the new abilities
220 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
221 "command sequence" vs. "recipe" syntax.
222 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
223 after a define, to create variables with those flavors.
225 2009-05-25 Paul Smith <psmith@gnu.org>
227 Reworked the parser for variable assignments to allow multiple
228 modifiers, and in any order. Also allows variable and
229 prerequisites to be modifier names ('export', 'private', etc.)
231 * NEWS: Add notes about user-visible changes.
233 * read.c (struct vmodifiers): Remember what modifiers were seen.
234 (parse_var_assignment): New function to parse variable assignments.
235 (eval): Call the new function. Handle variable assignments earlier.
237 * variable.c (parse_variable_definition): Only parse; don't create var.
238 (assign_variable_definition): Call parse, then create the var.
240 2009-05-24 Paul Smith <psmith@gnu.org>
242 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
243 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
245 2009-03-14 Eli Zaretskii <eliz@gnu.org>
247 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
248 Fixes Savannah bug #25412.
250 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
251 prototype for xmalloc.
252 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
253 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
254 Loop over an array of extensions, instead of duplicating the same
255 code inline. Use SearchPath followed by CreateFile, instead of
256 the obsolete OpenFile. Fixes Savannah bug #17277.
257 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
258 to `find_file'. Fixes Savannah bug #25662.
260 2009-03-07 Eli Zaretskii <eliz@gnu.org>
262 * function.c (func_shell): Don't close pipedes[1] if it is -1.
263 Fixes Savannah bug #20495.
265 2009-02-28 Ralf Wildenhues <address@hidden>
267 * doc/make.texi (Instead of Execution): Document interaction of
268 -t with phony targets.
270 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
272 Introduce a new keyword "private" which applies to target-specific
273 variables and prevents their values from being inherited.
275 * variable.h (struct variable): Add private_var flag to each variable.
276 Add a flag to specify which list entry switches to the parent target.

312 -jN without Unixy shell. Remove obsolete text about not supplying
313 Visual Studio project files (we do supply them). Modify text to
314 prefer GCC builds to MSC builds.
316 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
318 * doc/make.texi (Empty Targets): Fix typo.
320 2008-03-27 Paul Smith <psmith@gnu.org>
322 Fix Savannah bug #22379:
323 * ar.c (ar_glob_match): Zero the allocated structure.
324 * read.c (parse_file_seq): Ditto.
326 2008-03-08 Brian Dessent <brian@dessent.net>
328 * maintMakefile: Update Translation Project location.
330 2008-01-26 Eli Zaretskii <eliz@gnu.org>
332 * variable.c (target_environment): Don't use shell_var if its
333 `value' field is NULL.
335 2007-12-22 Eli Zaretskii <eliz@gnu.org>
337 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
339 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
340 (TEXINFOS): Value changed to `doc/make.texi'.
341 (.SUFFIXES): Use .texi instead of .texinfo.
342 (make.info, make.dvi): Depend on doc/make.texi.
343 (.texi.info): New target, instead of ".texinfo.info". Change -I
344 switch to $(MAKEINFO) to look in doc/. Use --no-split.
345 (.texi): New target, instead of ".texinfo". Change -I switch to
346 $(MAKEINFO) to look in doc/. Use --no-split.
347 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
348 switch to $(MAKEINFO) to look in doc/.
349 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
350 "*.i[0-9][0-9]" (due to --no-split above).
351 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
352 (html, make_1.html): New targets.
353 (.PHONY): Add "html".
354 (.SUFFIXES): Add .html.
356 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
358 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
359 HAVE_DECL_SYS_SIGLIST.
361 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
362 build does not use child_execute_job.
364 * variable.c (define_automatic_variables) [__MSDOS__]: Always
365 export the SHELL environment variable to the child.
367 2007-12-22 Eli Zaretskii <eliz@gnu.org>
369 * config.h.W32: Include sys/types.h.

376 2007-11-04 Paul Smith <psmith@gnu.org>
378 * doc/make.texi: Convert references to "commands", "command
379 lines", and "command script" to "recipe".
381 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
384 2007-10-27 Bruno Haible <bruno@clisp.org>
386 * remake.c (f_mtime): Print time difference values between 100 and
387 ULONG_MAX in fixed-point notation rather than in exponention notation.
389 2007-10-12 Eli Zaretskii <eliz@gnu.org>
391 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
392 a more complex value than a simple shell: if it's not a default
393 shell now then expand it and see if is a default shell then.
395 2007-10-10 Eli Zaretskii <eliz@gnu.org>
397 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
398 pathnames, with const strings.
399 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
400 from the template (used for building from CVS, not a dist).
402 2007-10-10 Paul Smith <psmith@gnu.org>
404 * make.h: Add a prototype for w32_kill() (change suggested by
405 Yongwei Wu <wuyongwei@gmail.com>).
407 2007-09-21 Eli Zaretskii <eliz@gnu.org>
409 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
412 2007-09-12 Paul Smith <psmith@gnu.org>
414 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
415 Provided by Diego Biurrun <diego@biurrun.de>
416 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
417 Provided by Diego Biurrun <diego@biurrun.de>
419 2007-09-11 Paul Smith <psmith@gnu.org>
421 * doc/make.texi (Special Variables): Moved this into the "How to
422 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
423 (MAKEFILE_LIST) No longer a section; this was added into the
424 "Special Variables" section.
425 (Rule Introduction): Reference .RECIPEPREFIX.
426 (Simple Makefile): Ditto.
427 (Rule Syntax): Ditto.
428 (Command Syntax): Ditto.
429 (Error Messages): Ditto.
431 2007-09-10 Paul Smith <psmith@gnu.org>
433 * commands.c (print_commands): Don't print an extra line in the
434 command scripts. Prefix the command scripts with cmd_prefix, not \t.
436 * read.c (construct_include_path): Add the full string to the cache; we
437 were chopping the last char.
439 * NEWS: Announce the .RECIPEPREFIX special variable.
440 * variable.c (lookup_special_var): Rename from handle_special_var().
441 (lookup_variable): Call the new name.
442 (set_special_var): New function: handle setting of special variables.
443 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
444 (do_variable_definition): Call it.
445 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
446 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
447 * main.c (main): Create the .RECIPEPREFIX special variable.
448 * read.c (eval): Remove the cmd_prefix characters from the command
449 scripts here, so they're not stored in the commands array at all,
450 rather than waiting and stripping them out during command construction.
451 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
453 2007-08-15 Paul Smith <psmith@gnu.org>
455 * doc/make.texi (GNU Free Documentation License): The fdl.texi
456 file has had the section info removed, so add some to make.texi
457 before we include it.
459 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
461 * remake.c (check_dep): Reset the target state for intermediate
462 files. They might have been considered before but not updated
463 then (order-only for example) but they will be this time.
464 Fixes Savannah bug #'s 3330 and 15919.
466 2007-07-21 Eli Zaretskii <eliz@gnu.org>
468 Fix Savannah bug #20549:
469 * function.c (func_shell): Call construct_command_argv with zero
471 * job.c (construct_command_argv_internal): New argument FLAGS; all
473 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
475 * job.h (construct_command_argv_internal): Update prototype.
477 2007-07-13 Paul Smith <psmith@gnu.org>
479 * file.c (expand_deps): Use variable_buffer as the start of the
480 buffer, not the original pointer (in case it was reallocated).
481 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
482 Fixes Savannah bug #20452.
484 2007-07-04 Paul Smith <psmith@gnu.org>
486 * (ALL FILES): Update to GPLv3.
487 * (ALL FILES): Update copyright for 2007.
489 * main.c (print_version): Move the host type info to the second line.
491 2007-06-29 Thiemo Seufer <ths@mips.com>
493 * maintMakefile: Update Translation Project location.
495 2007-06-13 Paul Smith <psmith@gnu.org>
497 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
498 "Expansion of a deferred"
499 Fixes Savannah bug #20018.
501 * expand.c (variable_expand_for_file): Preserve the value of
502 reading_file rather than setting it to 0 at the end.
503 Fixes Savannah bug #20033.
505 2007-05-11 Paul Smith <psmith@gnu.org>
507 * job.c (new_job): Add debug info to specify where make found the
508 command script it is running to build a target.
509 Fixes Savannah bug #18617.
511 * default.c (default_suffixes,default_suffix_rules,default_variables):
512 Add support for Objective C. Fixes Savannah bug #16389.
513 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
515 * function.c (func_lastword): Initialize p.
517 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
518 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
519 Dave Korn <dave.korn@artimi.com>
521 2007-05-08 Paul Smith <psmith@gnu.org>
523 Fix Savannah bug #19656:
525 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
527 * make.h: Change all case-insensitive string compares to use
528 strcasecmp() (from POSIX). If we don't have that but do have one
529 of the others, define strcasecmp to be one of those instead. If
530 we don't have any, declare a prototype for our own version.
532 * misc.c (strcasecmp): Use this if we can't find any native
533 case-insensitive string comparison function.
534 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
535 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
537 * job.c (_is_unixy_shell, construct_command_argv_internal): Use

540 instead of strcmpi().
541 * acinclude.m4: Remove the strcasecmp() check from here.
543 2007-03-21 Paul Smith <psmith@gnu.org>
545 * configure.in: Don't turn on case-insensitive file system support
546 if --disable-... is given. Fixes Savannah bug #19348.
548 2007-03-19 Paul Smith <psmith@gnu.org>
550 * ALL: Use the strcache for all file name strings, or other
551 strings which we will never free. The goal is to save memory by
552 avoiding duplicate copies of strings. However, at the moment this
553 doesn't save much memory in most situations: due to secondary
554 expansion we actually save prerequisite lists twice (once before
555 the secondary expansion, and then again after it's been parsed
556 into individual file names in the dep list). We will resolve this
557 in a future change, by doing the parsing up-front for targets
558 where secondary expansion is not set.
560 Moving things into the strcache also allows us to use const
561 pointers in many more places.
563 2007-01-03 Paul Smith <psmith@gnu.org>
565 * make.h (ENULLLOOP): Reset errno after each failed invocation of
566 the function, not just the first. Fixes Savannah bug #18680.
568 2006-11-18 Paul Smith <psmith@gnu.org>
570 * strcache.c (strcache_add_len): Don't allocate a new buffer
571 unless the string is not already nil-terminated. Technically this
572 is a violation of the standard, since we may be passed an array
573 that is not long enough to test one past. However, in make this
574 is never true since we only use nil-terminated strings or
577 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
579 * main.c: New global cmd_prefix, defaults to '\t'.
580 * job.c (construct_command_argv_internal): Use cmd_prefix instead
584 (dir_contents_file_exists_p): Check for an error return from
585 readdir(), just in case.

606 2006-10-21 Paul Smith <psmith@gnu.org>
609 * arscan.c: Constified.
611 2006-09-30 Paul Smith <psmith@gnu.org>
613 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
614 point to lastword since the example was updated.
615 Fixes Savannah bug #16304.
616 (Secondary Expansion): Correct example description.
617 Fixes Savannah bug #16468.
618 (Makefile Contents): Clarify that comments cannot appear within
619 variable references or function calls.
620 Fixes Savannah bug #16577.
621 (Special Targets): Clarify how .NOTPARALLEL works in recursion.

674 that don't have extended grep.
675 (cvsclean): Use $(PERL) instead of perl.

743 Declare and define sh_chars_sh[].
745 2006-03-23 Paul D. Smith <psmith@gnu.org>
747 * configure.in: Look for build.sh.in in $srcdir so it will be
748 built for remote configurations as well.
750 * Makefile.am: Make sure to clean up build.sh during distclean.
751 Fixes Savannah bug #16166.
753 * misc.c (log_access): Takes a const char *.
754 * function.c (fold_newlines): Takes an unsigned int *.

804 (allocated_variable_append): Don't expand the final result.
805 Fixes Savannah bug #15913.
807 2006-03-09 Paul Smith <psmith@gnu.org>
809 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
810 listed non-existent files as changed. Turns out there's a bug in
811 the Linux kernel builds which means that this change causes
812 everything to rebuild every time. We will re-introduce this fix
813 in the next release, to give them time to fix their build system.
814 Fixes Savannah bug #16002.
815 Introduces Savannah bug #16051.

835 string values to avoid memory leaks.
837 * expand.c (recursively_expand_for_file): Only set reading_file to
838 an initialized value.
840 * implicit.c (pattern_search): We need to make a copy of the stem
841 if we get it from an intermediate dep, since those get freed.

850 * job.c (construct_command_argv_internal): Fix last change.
852 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
853 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
854 the calls to _beginthreadex.
856 * expand.c (recursively_expand_for_file): Initialize `save' to
857 prevent compiler warnings.
859 2006-02-18 Eli Zaretskii <eliz@gnu.org>
861 * job.c (construct_command_argv_internal): Don't create a temporary
862 script/batch file if we are under -n. Call _setmode to switch the
863 script file stream to text mode.

867 * variable.c (merge_variable_set_lists): Don't try to merge the
868 global_setlist. Not only is this useless, but it can lead to
869 circularities in the linked list, if global_setlist->next in one
870 list gets set to point to another list which also ends in

874 2006-02-15 Paul D. Smith <psmith@gnu.org>
876 Fix for Savannah bug #106.
878 * expand.c (expanding_var): Keep track of which variable we're
879 expanding. If no variable is being expanded, it's the same as
881 * make.h (expanding_var): Declare it.
882 * expand.c (recursively_expand_for_file): Set expanding_var to the
883 current variable we're expanding, unless there's no file info in
884 it (could happen if it comes from the command line or a default
885 variable). Restore it before we exit.

901 an impossible file, free it.
902 * variable.c (free_variable_set): New function.
903 * variable.h: Declare it.
905 * read.c (read_all_makefiles): Makefile names are kept in the
906 strcache, so there's never any need to alloc/free them.

910 archive support is enabled.
911 * doc/make.texi (Special Variables): Document it.

921 * (ALL FILES): Updated copyright and license notices.
923 2006-02-10 Paul D. Smith <psmith@gnu.org>
925 A new internal capability: the string cache is a read-only cache
926 of strings, with a hash table interface for fast lookup. Nothing
927 in the cache will ever be freed, so there's no need for reference
928 counting, etc. This is the beginning of a full solution for
929 Savannah bug #15182, but for now we only store makefile names here.
931 * strcache.c: New file. Implement a read-only string cache.
932 * make.h: Add prototypes for new functions.
933 * main.c (initialize_global_hash_tables): Initialize the string cache.
934 (print_data_base): Print string cache stats.

963 * vpath.c (selective_vpath_search): If the file we find has a
964 timestamp from -o or -W, use that instead of the real time.

1015 * remake.c (update_goal_chain): Set g->changed instead of
1016 incrementing it, as it is only 8-bit wide, and could overflow if

1042 all callers changed. Don't close the temporary file; return its
1043 file descriptor instead. New arg FD allows to return the file
1045 (construct_command_argv_internal): Use _fdopen instead of fopen to
1046 open the batch file.

1078 handling of backslash-newline sequences. Mention the differences
1079 on MS-DOS and MS-Windows.
1081 * NEWS: More details about building the MinGW port and a pointer
1082 to README.W32. Fix the section name that describes the new
1083 backward-incompatible processing of backslash-newline sequences.
1084 The special processing of SHELL set to "cmd" is only relevant to
1085 MS-Windows, not MS-DOS.
1087 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1089 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1090 to DWORD, to avoid compiler warnings.
1091 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1092 use %ld in format, to avoid compiler warnings.
1094 * doc/make.texi (Special Targets): Fix a typo.
1095 (Appending): Fix cross-reference to Setting.
1096 (Special Variables, Secondary Expansion, File Name Functions)
1097 (Flavor Function, Pattern Match, Quick Reference): Ensure two
1098 periods after a sentence.
1099 (Execution): Add @: after "e.g.".
1100 (Environment): Fix punctuation.
1101 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
1102 (Shell Function, Target-specific): Add @: after "vs."
1104 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
1106 * read.c (record_target_var): Initialize variable's export field
1107 with v_default instead of leaving it "initialized" by whatever
1108 garbage happened to be on the heap.
1110 2005-12-12 Paul D. Smith <psmith@gnu.org>
1112 * make.1: Fix some display errors and document all existing options.
1113 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1115 2005-12-11 Paul D. Smith <psmith@gnu.org>
1117 * implicit.c (pattern_search): If 2nd expansion is not set for
1118 this implicit rule, replace the pattern with the stem directly,
1119 and don't re-expand the variable list. Along with the other
1120 .SECONDEXPANSION changes below, fixes bug #13781.
1122 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1124 * implicit.c (pattern_search): Mark other files that this rule
1125 builds as targets so that they are not treated as intermediates
1126 by the pattern rule search algorithm. Fixes bug #13022.
1128 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1130 * remake.c (notice_finished_file): Propagate the change of
1131 modification time to all the double-colon entries only if
1132 it is the last one to be updated. Fixes bug #14334.
1134 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
1136 * function.c (func_flavor): Implement the flavor function which
1137 returns the flavor of a variable.
1138 * doc/make.texi (Functions for Transforming Text): Document it.
1139 * NEWS: Add it to the list of new functions.
1141 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1143 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1145 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1146 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1148 2005-10-26 Paul Smith <psmith@gnu.org>
1150 * read.c (record_files): Don't set deps flags if there are no deps.
1151 * maintMakefile: We only need to build the templates when we are
1152 creating a distribution, so don't do it for "all".
1154 2005-10-24 Paul D. Smith <psmith@gnu.org>
1156 Make secondary expansion optional: its enabled by declaring the
1157 special target .SECONDEXPANSION.
1159 * NEWS: Update information on second expansion capabilities.
1160 * doc/make.texi (Secondary Expansion): Document the
1161 .SECONDEXPANSION special target and its behavior.
1162 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1163 prerequisite list was found in a static pattern rule.
1164 (free_dep_chain): Declare a prototype.
1165 * file.c (parse_prereqs): New function: break out some complexity
1167 (expand_deps): If we aren't doing second expansion, replace % with
1168 the stem for static pattern rules. Call the new function.
1169 * filedef.h (parse_prereqs): Declare a prototype.
1170 * implicit.c (pattern_search): Initialize the new staticpattern
1172 * main.c (second_expansion): Declare a global variable to remember
1173 if the special target has been seen. Initialize the new
1174 staticpattern field for prerequisites.
1175 * make.h: Extern for second_expansion.
1176 * misc.c (free_dep_chain): New function: frees a struct dep list.
1177 * read.c (read_all_makefiles): Initialize the staticpattern field.
1178 (eval_makefile): Ditto.
1179 (record_files): Check for the .SECONDEXPANSION target and set
1180 second_expansion global if it's found.
1181 Use the new free_dep_chain() instead of doing it by hand.
1182 Set the staticpattern field for prereqs of static pattern targets.
1184 2005-10-16 Paul D. Smith <psmith@gnu.org>
1186 * main.c (main): Set CURDIR to be a file variable instead of a
1187 default, so that values of CURDIR inherited from the environment
1188 won't override the make value.
1190 2005-09-26 Paul D. Smith <psmith@gnu.org>
1192 * job.c (construct_command_argv_internal): If the line is empty
1193 remember to free the temporary argv strings.
1196 2005-09-16 Paul D. Smith <psmith@gnu.org>
1198 * job.c (start_job_command): The noerror flag is a boolean (single
1199 bit); set it appropriately.
1200 Reported by Mark Eichin <eichin@metacarta.com>
1202 2005-08-29 Paul D. Smith <psmith@gnu.org>
1204 * function.c (func_error): On Windows, output from $(info ...)
1205 seems to come in the wrong order. Try to force it with fflush().
1207 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1209 * read.c (record_files): Move code that sets stem for static
1210 pattern rules out of the if (!two_colon) condition so it is
1211 also executed for two-colon rules. Fixes Savannah bug #13881.
1213 2005-08-08 Paul D. Smith <psmith@gnu.org>
1215 * make.h: Don't test that __STDC__ is non-0. Some compilers
1216 (Windows for example) set it to 0 to denote "ISO C + extensions".
1219 2005-08-07 Paul D. Smith <psmith@gnu.org>
1221 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1222 conditional (slightly different version of a fix from Eli).
1224 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1225 If make is running in parallel without -k and two jobs die in a
1226 row, but not too close to each other, then make will quit without
1227 waiting for the rest of the jobs to die.
1229 * main.c (die): Don't reset err before calling reap_children() the
1230 second time: we still want it to be in the error condition.
1231 * job.c (reap_children): Use a static variable, rather than err,
1232 to control whether or not the error message should be printed.
1234 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1236 * w32/subproc/sub_proc.c: Include signal.h.
1237 (process_pipe_io, process_file_io): Pass a pointer to a local
1238 DWORD variable to GetExitCodeProcess. If the exit code is
1239 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1241 * job.c [WINDOWS32]: Include windows.h.
1242 (main_thread) [WINDOWS32]: New global variable.
1243 (reap_children) [WINDOWS32]: Get the handle for the main thread
1244 and store it in main_thread.
1246 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1247 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1248 doing anything else. When we are done, close the main thread
1249 handle and exit with status 130.
1251 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1253 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1256 * main.c (find_and_set_default_shell): If found a DOSish shell,
1257 set sh_found and the value of default_shell, and report the
1258 findings in debug mode.
1260 * job.c (construct_command_argv_internal): Check unixy_shell, not
1261 no_default_sh_exe, to decide whether to use Unixy or DOSish
1264 * README.W32: Update with info about the MinGW build.
1266 * build_w32.bat: Support MinGW.
1268 * w32/subproc/build.bat: Likewise.
1270 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1271 printing DWORD args.
1273 * function.c (windows32_openpipe): Fix format strings for printing
1276 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1278 (start_job_command): Fix format string for printing the result of
1280 (start_job_command) [WINDOWS32]: Do not define.
1281 (exec_command): Fix format string for printing HANDLE args.
1283 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1284 to avoid compiler warnings.
1285 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1286 (Note: some of these fixes were submitted independently by J. Grant)
1288 2005-07-30 J. Grant <jg@jguk.org>
1290 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1291 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1292 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1294 2005-07-15 Paul Smith <psmith@gnu.org>
1296 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1297 we don't have a POSIX shell, then revert to the old
1298 backslash-newline behavior (where they are stripped).
1301 2005-07-08 Paul D. Smith <psmith@gnu.org>
1303 * config.h.W32.template: Reorder to match the standard config.h,
1304 for easier comparisons.
1305 From J. Grant <jg@jguk.org>
1307 * maintMakefile: Remove .dep_segment before overwriting it, in
1308 case it's not writable or noclobber is set.
1309 * expand.c (variable_expand_string): Cast result of pointer
1310 arithmetic to avoid a warning.
1311 * main.c (switches): Add full-fledged final initializer.
1313 2005-07-06 Paul D. Smith <psmith@gnu.org>
1315 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1316 * signame.c (strsignal): If we found _sys_siglist[] or
1317 __sys_siglist[] use those instead of sys_siglist[].
1318 From Albert Chin <china@thewrittenword.com>
1320 2005-07-04 Paul D. Smith <psmith@gnu.org>
1322 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1323 globfree(); set up to use the GNU versions.
1324 From Martin Zinser <zinser@zinser.no-ip.info>
1326 2005-07-03 Paul D. Smith <psmith@gnu.org>
1328 From J. Grant <jg@jguk.org>:
1330 * README.W32.template: Update the Windows and tested MSVC versions.
1331 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1332 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1333 * build_w32.bat: Ditto.
1334 * w32/subproc/build.bat: Ditto.
1336 2005-06-28 Paul D. Smith <psmith@gnu.org>
1338 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1339 declaration was checked but not present.
1341 2005-06-27 Paul D. Smith <psmith@gnu.org>
1343 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1344 to unsigned long. Fixes Savannah bug #13550.
1346 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1347 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1348 Fixes Savannah bug #13551.
1350 2005-06-26 Paul D. Smith <psmith@gnu.org>
1352 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1353 it if ANSI_STRING is not set.
1355 2005-06-25 Paul D. Smith <psmith@gnu.org>
1357 * read.c (eval): If no filenames are passed to any of the
1358 "include" variants, don't print an error.
1359 * doc/make.texi (Include): Document this.
1360 Fixes Savannah bug #1761.
1362 * job.c (construct_command_argv_internal): Sanitize handling of
1363 backslash/newline pairs according to POSIX: that is, keep the
1364 backslash-newline in the command script, but remove a following
1365 TAB character, if present. In the fast path, make sure that the
1366 behavior matches what the shell would do both inside and outside
1367 of quotes. In the slow path, quote the backslash and put a
1368 literal newline in the string.
1369 Fixes Savannah bug #1332.
1370 * doc/make.texi (Execution): Document the new behavior and give
1372 * NEWS: Make a note of the new behavior.
1374 * make.h [WINDOWS32]: #include <direct.h>.
1375 Fixes Savannah bug #13478.
1377 * remake.c (name_mtime): If the stat() of a file fails and the -L
1378 option was given and the file is a symlink, take the best mtime of
1379 the symlink we can get as the mtime of the file and don't fail.
1380 Fixes Savannah bug #13280.
1382 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1383 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1384 inside a variable reference. Make this function static as it's
1386 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1387 parsing an unexpanded line looking for semicolons.
1388 Fixes Savannah bug #1454.
1389 * misc.c (remove_comments): Move this to read.c and make it static
1390 as it's only used there. Call find_char_unquote() with new arg.
1391 * make.h: Remove prototypes for find_char_unquote() and
1392 remove_comments() since they're static now.
1394 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1395 its export flag and obtain its value. When we need to re-exec,
1396 increment the value and add it into the environment.
1397 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1398 * NEWS: Mention MAKE_RESTARTS.
1399 * main.c (always_make_set): New variable. Change the -B option to
1400 set this one instead.
1401 (main): When checking makefiles, only set always_make_flag if
1402 always_make_set is set AND the restarts flag is 0. When building
1403 normal targets, set it IFF always_make_set is set.
1404 (main): Avoid infinite recursion with -W, too: only set what-if
1405 files to NEW before we check makefiles if we've never restarted
1406 before. If we have restarted, set what-if files to NEW _after_ we
1408 Fixes Savannah bug #7566:
1410 2005-06-17 Paul D. Smith <psmith@gnu.org>
1412 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1413 in the prerequisites list.
1415 2005-06-12 Paul D. Smith <psmith@gnu.org>
1417 Fix Savannah bug # 1328.
1419 * configure.in: Check for atexit().
1420 * misc.c (close_stdout): Test stdout to see if writes to it have
1421 failed. If so, be sure to exit with a non-0 error code. Based on
1422 code found in gnulib.
1423 * make.h: Prototype.
1424 * main.c (main): Install close_stdout() with atexit().
1426 2005-06-10 Paul D. Smith <psmith@gnu.org>
1428 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1430 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1431 headers; make vmsWaitForChildren() static; extern vmsify().
1432 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1433 Don't create child_execute_job() here (it's in vmsjobs.c).
1434 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1436 2005-06-09 Paul D. Smith <psmith@gnu.org>
1438 * variable.c (push_new_variable_scope): File variables point
1439 directly to the global_setlist variable. So, inserting a new
1440 scope in front of that has no effect on those variables: they
1441 don't go through current_variable_set_list. If we're pushing a
1442 scope and the current scope is global, push it "the other way" so
1443 that the new setlist is in the global_setlist variable, and
1444 next points to a new setlist with the global variable set.
1445 (pop_variable_scope): Properly undo a push with the new
1447 Fixes Savannah bug #11913.
1449 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1451 * job.c (reap_children): Don't die of the command failed but
1452 the dontcare flag is set. Fixes Savannah bug #13216.
1454 * implicit.c (pattern_search): When creating a target from
1455 an implicit rule match, lookup pattern target and set precious
1456 flag in a newly created target. Fixes Savannah bug #13218.
1458 2005-05-13 Paul D. Smith <psmith@gnu.org>
1460 Implement "if... else if... endif" syntax.
1462 * read.c (eval): Push all checks for conditional words ("ifeq",
1463 "else", etc.) down into the conditional_line() function.
1464 (conditional_line): Rework to allow "else if..." clause. New
1465 return value -2 for lines which are not conditionals. The
1466 ignoring flag can now also be 2, which means "already parsed a
1467 true branch". If that value is seen no other branch of this
1468 conditional can be considered true. In the else parsing if there
1469 is extra text after the else, invoke conditional_line()
1470 recursively to see if it's another conditional. If not, it's an
1471 error. If so, raise the conditional value to this level instead
1472 of creating a new conditional nesting level. Special check for
1473 "else" and "endif", which aren't allowed on the "else" line.
1474 * doc/make.texi (Conditional Syntax): Document the new syntax.
1476 2005-05-09 Paul D. Smith <psmith@gnu.org>
1478 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1479 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1480 recurses to the w32 directory, even on non-Windows systems. Use
1481 the method suggested in the automake manual.
1482 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1483 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1485 2005-05-07 Paul D. Smith <psmith@gnu.org>
1487 * main.c (die): If we're dying with a fatal error (not that a
1488 command has failed), write back any leftover tokens before we go.
1490 * job.c (set_child_handler_action_flags): If there are jobs
1491 waiting for the load to go down, set an alarm to go off in 1
1492 second. This allows us to wake up from a potentially long-lasting
1493 read() and start a new job if the load has gone down. Turn it off
1495 (job_noop): Dummy signal handler function.
1496 (new_job): Invoke it with the new semantics.
1498 * docs/make.texi: Document secondary expansion. Various cleanups
1501 2005-05-03 Paul D. Smith <psmith@gnu.org>
1503 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1504 the targets which are to ultimately be made are called "goals";
1505 see the GNU make manual. Also, MAKECMDGOALS, etc.
1507 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1508 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1509 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1511 2005-05-02 Paul D. Smith <psmith@gnu.org>
1513 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1514 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1515 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1516 functions to vmsjobs.c. #include it into jobs.c.
1518 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1519 jobserver tokens. I found that this happens when an exported
1520 recursive variable contains a $(shell ...) function reference: in
1521 this situation we could "forget" to write back a token.
1523 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1524 we have. It's not reliable to depend on the number of children in
1525 our linked list so keep a separate count.
1526 (new_job): Check jobserver_tokens rather than children &&
1527 waiting_jobs. Increment jobserver_tokens when we get one.
1528 (free_child): If jobserver_tokens is 0, internal error. If it's
1529 >1, write a token back to the jobserver pipe (we don't write a
1530 token for the "free" job). Decrement jobserver_tokens.
1532 * main.c: Add variable master_job_slots.
1533 (main): Set it to hold the number of jobs requested if we're the
1534 master process, when using the jobserver.
1535 (die): Sanity checks: first test jobserver_tokens to make sure
1536 this process isn't holding any tokens we didn't write back.
1537 Second, if master_job_slots is set count the tokens left in the
1538 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1540 2005-04-24 Paul D. Smith <psmith@gnu.org>
1542 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1543 with -l# can lose jobserver tokens, because waiting jobs are not
1544 consulted properly when checking for the "free" token.
1546 * job.c (free_child): Count waiting_jobs as having tokens.
1547 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1548 handle jobs waiting for the load to drop.
1550 2005-04-23 Paul D. Smith <psmith@gnu.org>
1552 * main.c (main): Be careful to not core if a variable setting in
1553 the environment doesn't contain an '='. This is illegal but can
1554 happen in broken setups.
1555 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1557 2005-04-12 Paul D. Smith <psmith@gnu.org>
1559 The second expansion feature causes significant slowdown. Timing
1560 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1561 read the makefile before the feature, to 11+s to do the same
1562 operations after the feature. Additionally, memory usage
1563 increased drastically. To fix this I added some intelligence that
1564 avoids the overhead of the second expansion unless it's required.
1566 * dep.h: Add a new boolean field, need_2nd_expansion.
1568 * read.c (eval): When creating the struct dep for the target,
1569 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1570 (record_files): If there's a "%" in a static pattern rule, it gets
1571 converted to "$*" so set need_2nd_expansion to 1.
1573 * file.c (expand_deps): Rework to be more efficient. Only perform
1574 initialize_file_variables(), set_file_variables(), and
1575 variable_expand_for_file() if the need_2nd_expansion is set.
1577 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1578 (pattern_search): Ditto.
1579 * main.c (handle_non_switch_argument): Ditto.
1581 * read.c (read_all_makefiles): Ditto.
1582 (eval_makefile): Ditto.
1584 2005-04-07 Paul D. Smith <psmith@gnu.org>
1586 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1587 * variable.c (sync_Path_environment): Ditto.
1588 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1590 * main.c (main): Define the .FEATURES variable.
1591 * NEWS: Announce .FEATURES.
1592 * doc/make.texi (Special Variables): Document .FEATURES.
1594 * remake.c (check_dep): If a file is .PHONY, update it even if
1595 it's marked intermediate. Fixes Savannah bug #12331.
1597 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1599 * file.c (expand_deps): Factor out the second expansion and
1600 prerequisite line parsing logic from snap_deps().
1602 * file.c (snap_deps): Use expand_deps(). Expand and parse
1603 prerequisites of the .SUFFIXES special target first. Fixes
1604 Savannah bug #12320.
1606 2005-03-13 Paul D. Smith <psmith@gnu.org>
1608 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1611 2005-03-11 Paul D. Smith <psmith@gnu.org>
1613 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1614 available, not undefined (from Earnie Boyd).
1616 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1618 * implicit.c (pattern_search): Mark an intermediate target as
1619 precious if it happened to be a prerequisite of some (other)
1620 target. Fixes Savannah bug #12267.
1622 2005-03-09 Paul D. Smith <psmith@gnu.org>
1624 * read.c (eval_makefile): Add alloca(0).
1625 (eval_buffer): Ditto.
1627 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1629 * main.c (main): Use o_file instead of o_default when defining
1630 the .DEFAULT_TARGET special variable.
1631 * read.c (eval): Use define_variable_global() instead of
1632 define_variable() when setting new value for the .DEFAULT_TARGET
1633 special variable. Fixes Savannah bug #12266.
1635 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1637 * imlicit.c (pattern_search): Mark files for which an implicit
1638 rule has been found as targets. Fixes Savannah bug #12202.
1640 2005-03-04 Paul D. Smith <psmith@gnu.org>
1643 * doc/make.texi (Automatic Variables): Document $|.
1645 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1647 * read.c (record_files): Instead of substituting % with
1648 actual stem value in dependency list replace it with $*.
1649 This fixes stem triple expansion bug.
1651 * implicit.c (pattern_search): Copy stem to a separate
1652 buffer and make it a properly terminated string. Assign
1653 this buffer instead of STEM (which is not terminated) to
1654 f->stem. Instead of substituting % with actual stem value
1655 in dependency list replace it with $*. This fixes stem
1656 triple expansion bug.
1658 2005-03-01 Paul D. Smith <psmith@gnu.org>
1660 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1661 on Windows, as it takes a handle not a pid. Just exit.
1662 Fix from patch #3679, provided by Alessandro Vesely.
1664 * configure.in: Update check for sys_siglist[] from autoconf manual.
1665 * signame.c (strsignal): Update to use the new autoconf macro.
1667 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1669 * read.c (record_files): Add a check for the list of prerequisites
1670 of a static pattern rule being empty. Fixes Savannah bug #12180.
1672 2005-02-28 Paul D. Smith <psmith@gnu.org>
1674 * doc/make.texi (Text Functions): Update docs to allow the end
1675 ordinal for $(wordlist ...) to be 0.
1676 * function.c (func_wordlist): Fail if the start ordinal for
1677 $(wordlist ...) is <1. Matches documentation.
1678 Resolves Savannah support request #103195.
1680 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1681 previously we were stopping when !-q, exactly the opposite. This
1682 has been wrong since version 1.34, in 1994!
1683 (update_file): If we got an error don't break out to run more
1684 double-colon rules: just return immediately.
1685 Fixes Savannah bug #7144.
1687 2005-02-27 Paul D. Smith <psmith@gnu.org>
1689 * misc.c (end_of_token): Make argument const.
1690 * make.h: Update prototype.
1692 * function.c (abspath, func_realpath, func_abspath): Use
1693 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1694 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1695 * read.c (record_files): Ditto.
1696 * variable.c (do_variable_definition): Ditto.
1698 * function.c (func_error): Create a new function $(info ...) that
1699 simply prints the message to stdout with no extras.
1700 (function_table_init): Add new function to the table.
1701 * NEWS: Add $(info ...) reference.
1702 * doc/make.texi (Make Control Functions): Document it.
1704 New feature: if the system supports symbolic links, and the user
1705 provides the -L/--check-symlink-time flag, then use the latest
1706 mtime between the symlink(s) and the target file.
1708 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1709 readlink(). If both are available, define MAKE_SYMLINKS.
1710 * main.c: New variable: check_symlink_flag.
1711 (usage): Add a line for -L/--check-symlink-times to the help string.
1712 (switches): Add -L/--check-symlink-times command line argument.
1713 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1714 print a warning and disable it again.
1715 * make.h: Declare check_symlink_flag.
1716 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1717 if the file is a symlink then check each link in the chain and
1718 choose the NEWEST mtime we find as the mtime for the file. The
1719 newest mtime might be the file itself!
1720 * NEWS: Add information about this new feature.
1721 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1723 Avoid core dumps described in Savannah bug # 12124:
1725 * file.c: New variable snapped_deps remember whether we've run
1727 (snap_deps): Set it.
1728 * filedef.h: Extern it.
1729 * read.c (record_files): Check snapped_deps; if it's set then
1730 we're trying to eval a new target/prerequisite relationship from
1731 within a command script, which we don't support. Fatal.
1733 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1735 Implementation of the .DEFAULT_TARGET special variable.
1737 * read.c (eval): If necessary, update default_target_name when
1739 * read.c (record_files): Update default_target_file if
1740 default_target_name has changed.
1741 * main.c (default_target_name): Define.
1742 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1743 default_target_name is set use default_target_file as a root
1745 * filedef.h (default_target_name): Declare.
1746 * dep.h (free_dep_chain):
1747 * misc.c (free_dep_chain): Change to operate on struct nameseq
1748 and change name to free_ns_chain.
1749 * file.c (snap_deps): Update to use free_ns_chain.
1751 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1753 Implementation of the second expansion in explicit rules,
1754 static pattern rules and implicit rules.
1756 * read.c (eval): Refrain from chopping up rule's dependencies.
1757 Store them in a struct dep as a single dependency line. Remove
1758 the code that implements SySV-style automatic variables.
1760 * read.c (record_files): Adjust the code that handles static
1761 pattern rules to expand all percents instead of only the first
1762 one. Reverse the order in which dependencies are stored so that
1763 when the second expansion reverses them again they appear in
1764 the makefile order (with some exceptions, see comments in
1765 the code). Remove the code that implements SySV-style automatic
1768 * file.c (snap_deps): Implement the second expansion and chopping
1769 of dependency lines for explicit rules.
1771 * implicit.c (struct idep): Define an auxiliary data type to hold
1772 implicit rule's dependencies after stem substitution and
1775 * implicit.c (free_idep_chain): Implement.
1777 * implicit.c (get_next_word): Implement helper function for
1778 parsing implicit rule's dependency lines into words taking
1779 into account variable expansion requests. Used in the stem
1782 * implicit.c (pattern_search): Implement the second expansion
1783 for implicit rules. Also fixes bug #12091.
1785 * commands.h (set_file_variables): Declare.
1786 * commands.c (set_file_variables): Remove static specifier.
1788 * dep.h (free_dep_chain): Declare.
1789 * misc.c (free_dep_chain): Implement.
1791 * variable.h (variable_expand_for_file): Declare.
1792 * expand.c (variable_expand_for_file): Remove static specifier.
1794 * make.h (strip_whitespace): Declare.
1795 * function.c (strip_whitespace): Remove static specifier.
1797 2005-02-26 Paul D. Smith <psmith@gnu.org>
1799 * main.c (main): Check for ferror() when reading makefiles from stdin.
1800 Apparently some shells in Windows don't close pipes properly and
1803 2005-02-24 Jonathan Grant <jg@jguk.org>
1805 * configure.in: Add MinGW configuration options, and extra w32 code
1807 * Makefile.am: Add MinGW configuration options, and extra w32 code
1809 * main.c: Determine correct program string (after last \ without .exe).
1810 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1812 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1813 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1814 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1815 environment support.
1817 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1819 * function.c (func_shell): When initializing error_prefix, check
1820 that reading file name is not null. This fixes long-standing
1821 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1823 2005-02-09 Paul D. Smith <psmith@gnu.org>
1825 * maintMakefile: Update the CVS download URL to simplify them.
1826 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1827 downloading the .texi files from Savannah now.
1829 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1831 * main.c (handle_non_switch_argument): Only add variables to
1832 command_variables if they're not already there: duplicate settings
1833 waste space and can be confusing to read.
1835 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1836 this header is never included by non-WINDOWS32 code, and it
1837 requires <config.h> to define which isn't always included first.
1839 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1840 testing MINGW32 versions.
1842 * main.c (log_working_directory): flush stdout to be sure the WD
1843 change is printed before any stderr messages show up.
1845 2005-02-01 Paul D. Smith <psmith@gnu.org>
1847 * maintMakefile (po_repo): Update the GNU translation site URL.
1849 2004-12-01 Paul D. Smith <psmith@gnu.org>
1851 * main.c (main): Change char* env_shell to struct variable shell_var.
1852 * variable.c (target_environment): Use new shell_var.
1854 2004-11-30 Paul D. Smith <psmith@gnu.org>
1856 * configure.in: The old way we avoided creating build.sh from
1857 build.sh.in before build.sh.in exists doesn't work anymore; we
1858 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1859 the help!). This also keeps automake from complaining.
1860 * Makefile.am (README): Add a dummy target so automake won't
1861 complain that this file doesn't exist when we checkout from CVS.
1862 * maintMakefile (.dep_segment): Rewrite this rule since newer
1863 versions of automake don't provide DEP_FILES.
1865 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1867 Implementation of `realpath' and `abspath' built-in functions.
1869 * configure.in: Check for realpath.
1870 * function.c (abspath): Return an absolute file name that does
1871 not contain any `.' or `..' components, nor repeated `/'.
1872 * function.c (func_abspath): For each name call abspath.
1873 * function.c (func_realpath): For each name call realpath
1874 from libc or delegate to abspath if realpath is not available.
1875 * doc/make.texi (Functions for File Names): Document new functions.
1876 * doc/make.texi (Quick Reference): Ditto.
1878 2004-11-28 Paul D. Smith <psmith@gnu.org>
1880 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1881 arguments. Fixes bug #10252.
1883 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1885 * main.c (main): Set SHELL to v_noexport by default. Remember the
1886 original environment setting of SHELL in the env_shell variable.
1887 * main.h: Export new env_shell variable.
1888 * variable.c (target_environment): If we find a v_noexport
1889 variable for SHELL, add a SHELL variable with the env_shell value.
1890 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1891 * doc/make.texi (Variables/Recursion): Ditto.
1893 2004-11-28 Paul D. Smith <psmith@gnu.org>
1895 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1896 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1897 Patch by Alessandro Vesely.
1899 2004-11-12 Paul D. Smith <psmith@gnu.org>
1901 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1902 the command line if it's inside a string.
1903 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1905 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1907 * function.c (func_lastword): New function: return last word
1908 from the list of words.
1909 * doc/make.texi: Document $(lastword ). Fix broken links in
1910 Quick Reference section.
1912 2004-10-06 Paul D. Smith <psmith@gnu.org>
1914 Apply patch from Alessandro Vesely, provided with bug # 9748.
1915 Fix use of tmpnam() to work with Borland C.
1917 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1918 construction of a temporary filename, and call new function
1919 create_batch_filename().
1920 (create_batch_filename) [WINDOWS32]: New function to create a
1923 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1925 * read.c (record_target_var): Expand simple pattern-specific
1927 * variable.c (initialize_file_variables): Do not expand simple
1928 pattern-specific variable.
1930 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1932 * remake.c (update_file_1): When rebuilding makefiles inherit
1933 dontcare flag from a target that triggered update.
1935 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1937 * variable.c (initialize_file_variables): Mark pattern-specific
1938 variable as a per-target and copy export status.
1940 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1942 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1944 * implicit.c (pattern_search): When considering an implicit rule's
1945 prerequisite check that it is actually a target rather then
1946 just an entry in the file hashtable.
1948 2004-09-21 Paul D. Smith <psmith@gnu.org>
1950 * read.c (readstring): Fix some logic errors in backslash handling.
1951 (eval): Remove some unnecessary processing in buffer handling.
1952 (record_target_var): Assert that parse_variable_definition() succeeded.
1953 Reported by: Markus Mauhart <qwe123@chello.at>.
1955 * misc.c: Removed the sindex() function. All instances of this
1956 function were trivially replaceable by the standard strstr()
1957 function, and that function will always have better (or certainly
1958 no worse) performance than the very simple-minded algorithm
1959 sindex() used. This can matter with complex makefiles.
1960 * make.h: Remove the prototype for sindex().
1961 * function.c (subst_expand): Convert sindex() call to strstr().
1962 This means we no longer need to track the TLEN value so remove that.
1963 (func_findstring): Convert sindex() to strstr().
1964 * commands.c (chop_commands): Convert sindex() calls to strstr().
1965 Suggested by: Markus Mauhart <qwe123@chello.at>.
1967 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1968 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1969 If SHELL is set to CMD.EXE then assume it's batch-mode and
1970 non-unixy. I wrote the code differently from the patch, though,
1971 to make it safer. This also resolves bug #9174.
1973 2004-09-20 Paul D. Smith <psmith@gnu.org>
1975 * expand.c (variable_expand_string): Modify to invoke
1976 patsubst_expand() instead of subst_expand(); the latter didn't
1977 handle suffix patterns correctly.
1978 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1979 was used only from variable_expand_string() and is no longer used
1981 (func_subst): Ditto, on call to subst_expand().
1982 (patsubst_expand): Require the percent pointers to point to the
1983 character after the %, not to the % itself.
1984 * read.c (record_files): New call criteria for patsubst_expand().
1985 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1986 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1988 2004-09-19 Paul D. Smith <psmith@gnu.org>
1990 * function.c (subst_expand): Fix a check in by_word: look for a
1991 previous blank if we're beyond the beginning of the string, not
1992 the beginning of the word.
1993 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1995 2004-05-16 Paul D. Smith <psmith@gnu.org>
1997 * remake.c (update_goal_chain): Change the argument specifying
1998 whether we're rebuilding makefiles to be a global variable,
1999 REBUILDING_MAKEFILES.
2000 (complain): Extract the code that complains about no rules to make
2001 a target into a separate function.
2002 (update_file_1): If we tried to rebuild a file during the makefile
2003 rebuild phase and it was dontcare, then no message was printed.
2004 If we then try to build the same file during the normal build,
2005 print a message this time.
2006 (remake_file): Don't complain about un-remake-able files when
2007 we're rebuilding makefiles.
2009 2004-05-11 Paul D. Smith <psmith@gnu.org>
2011 * job.c (construct_command_argv_internal): OS/2 patches from
2012 Andreas Buening <andreas.buening@nexgo.de>.
2014 2004-05-10 Paul D. Smith <psmith@gnu.org>
2016 * remake.c (update_file): Don't walk the double-colon chain unless
2017 this is a double-colon rule. Fix suggested by Boris Kolpackov
2018 <boris@kolpackov.net>.
2020 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2021 * readme.vms: New section describing OpenVMS support and issues.
2022 * default.c (default_variables): Add support for IA64.
2023 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2024 without some privilege aborts make with the error
2025 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2026 pressing Ctrl+Y and the input device is no terminal. The change
2027 catches this error and just continues.
2029 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2031 2004-04-25 Paul D. Smith <psmith@gnu.org>
2033 * commands.c (set_file_variables): Set $< properly in the face of
2034 order-only prerequisites.
2035 Patch from Boris Kolpackov <boris@kolpackov.net>
2037 2004-04-21 Bob Byrnes <byrnes@curl.com>
2039 * main.c (main): Notice failures to remake makefiles.
2041 2004-03-28 Paul D. Smith <psmith@gnu.org>
2043 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2045 * job.c: No default shell for RISC OS.
2046 (load_too_high): Hard-code the return to 1.
2047 (construct_command_argv_internal): No sh_chars or sh_cmds.
2048 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2050 2004-03-20 Paul D. Smith <psmith@gnu.org>
2052 * variable.c (do_variable_definition): Don't append from the
2053 global set if a previous non-appending target-specific variable
2054 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2057 * expand.c (reference_variable): Don't give up on variables with
2058 no value that have the target-specific append flag set: they might
2059 have a value after all. Reported by Oliver Schmidt
2060 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2061 <nikulin@dx1cmd.inp.nsk.su>.
2063 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2064 refer to absolute pathnames in directories that don't exist: some
2065 portion of the makefile could create those directories before we
2066 match the pattern. Fixes bugs #775 and #108.
2068 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2070 * main.c (main): Free makefile_mtimes if we have any.
2071 * README.W32.template: Update documentation for the current status
2072 of the MS-Windows port.
2073 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2074 environment variable is sometimes already defined which causes the
2076 * main.c (debug_signal_handler): Only define this function if
2077 SIGUSR1 is available.
2079 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2081 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2082 * README.OS2.template: Documentation updates.
2083 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2084 link line for safety.
2085 * maintMakefile (build.sh.in): Remove an extraneous ")".
2086 * job.c (child_execute_job): Close saved FDs.
2087 * job.c (exec_command) [OS/2]: exec_command(): If the command
2088 can't be exec'ed and if the shell is not Unix-sh, then try again
2089 with argv = { "cmd", "/c", ... }. Normally, this code is never
2090 reached for the cmd shell unless the command really doesn't exist.
2091 (construct_command_argv_internal) [OS/2]: The code for cmd
2092 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2093 The CMD builtin commands are case insensitive so use strcasecmp().
2095 2004-03-19 Paul D. Smith <psmith@gnu.org>
2097 * read.c (do_define): Re-order line counter increment so the count
2098 is accurate (we were losing one line per define). Reported by
2099 Dave Yost <Dave@Yost.com>.
2101 2004-03-06 Paul D. Smith <psmith@gnu.org>
2103 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2105 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2106 * misc.c (message,error,fatal): Ditto.
2107 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2108 * config.h.W32.template: Ditto.
2109 * config.h-vms.template: Ditto.
2110 * config.ami.template: Ditto.
2112 2004-03-04 Paul D. Smith <psmith@gnu.org>
2114 * README.template: Add a note about broken /bin/sh on SunOS
2115 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2117 * misc.c (message, error, fatal): Don't use "..." if we're using
2118 varargs. ansi2knr should handle this but it doesn't work: it
2119 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2120 done. On many systems (SunOS for example) va_dcl is a #define.
2121 So, force the use of the non-"..." version on pre-ANSI compilers.
2123 * maintMakefile (sign-dist): Create some rules to help automate
2124 the new GNU ftp upload method.
2126 2004-02-24 Paul D. Smith <psmith@gnu.org>
2128 * config.h.W32.template: Add HAVE_STDARG_H
2129 * config.h-vms.template: Ditto.
2130 * config.ami.template: Ditto.
2132 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2134 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2135 * build_w32.bat: Remove extra "+".
2137 2004-02-23 Paul D. Smith <psmith@gnu.org>
2139 * make.h: Create an UNUSED macro to mark unused parameters.
2140 * (many): Clean up warnings by applying UNUSED, fixing
2141 signed/unsigned incompatibilities, etc.
2143 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2145 * filedef.h: Name the command_state enumeration.
2146 * file.c (set_command_state): Use the enumeration in the function
2149 * configure.in: Explicitly set SET_MAKE to empty, to disable
2150 MAKE=make even when no make already exists. Fix bug #3823.
2152 2004-02-22 Paul D. Smith <psmith@gnu.org>
2154 * maintMakefile: Perl script to clean up all non-CVS files. Use
2155 it on all the subdirectories for the cvs-clean target.
2157 * main.c (decode_switches): Require non-empty strings for all our
2158 string command-line options. Fixes Debian bug # 164165.
2160 * configure.in: Check for stdarg.h and varargs.h.
2161 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2162 for printing messages.
2163 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2168 A number of patches for OS/2 support from Andreas Buening
2169 <andreas.buening@nexgo.de>:
2171 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2172 disable the SIGCHLD handler.
2173 (reap_children) [OS/2]: Remove special handling of job_rfd.
2174 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2175 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2176 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2177 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2178 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2181 2004-02-21 Paul D. Smith <psmith@gnu.org>
2183 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2184 <mail@kristov.de> reports that if process_begin() fails we don't
2185 handle the error condition correctly in all cases.
2186 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2187 to have a newline on the message.
2189 * job.c (construct_command_argv_internal): Add "test" to UNIX
2190 sh_cmds[]. Fixes Savannah bug # 7606.
2192 2004-02-04 Paul D. Smith <psmith@gnu.org>
2194 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2195 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2196 Hartmut Becker <Hartmut.Becker@hp.com>.
2198 2004-01-21 Paul D. Smith <psmith@gnu.org>
2200 * job.c (load_too_high): Implement an algorithm to control the
2201 "thundering herd" problem when using -l to control job creation
2202 via the load average. The system only recomputes the load once a
2203 second but we can start many jobs in a second. To solve this we
2204 keep track of the number of jobs started in the last second and
2205 apply a weight to try to guess what a correct load would be.
2206 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2207 Also fixes bug #4693.
2208 (reap_children): Decrease the job count for this second.
2209 (start_job_command): Increase the job count for this second.
2211 * read.c (conditional_line): Expand the text after ifn?def before
2212 checking to see if it's a single word. Fixes bug #7257.
2214 2004-01-09 Paul D. Smith <psmith@gnu.org>
2216 * file.c (print_file): Recurse to print all targets in
2217 double-colon rules. Fixes bug #4518, reported (with patch) by
2218 Andrew Chatham <chatham@google.com>.
2220 2004-01-07 Paul D. Smith <psmith@gnu.org>
2222 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2223 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2224 AC_FUNC_SETVBUF_REVERSED.
2226 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2227 (MAKE Variable): Fix Savannah bug #4898.
2229 * job.c (construct_command_argv_internal): Add "!" to the list of
2230 shell escape chars. POSIX sh allows it to appear before a
2231 command, to negate the exit code. Fixes bug #6404.
2233 * implicit.c (pattern_search): When matching an implicit rule,
2234 remember which dependencies have the ignore_mtime flag set.
2235 Original fix provided in Savannah patch #2349, by Benoit
2236 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2238 2003-11-22 Paul D. Smith <psmith@gnu.org>
2240 * README.W32.template (Outputs): Clarification on -j with
2241 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2244 2003-11-02 Paul D. Smith <psmith@gnu.org>
2246 * function.c (func_if): Strip all the trailing whitespace from the
2247 condition, then don't expand it. Fixed bug # 5798.
2249 * expand.c (recursively_expand_for_file): If we're expanding a
2250 variable with no file context, then use the variable's context.
2253 2003-10-21 Paul D. Smith <psmith@gnu.org>
2255 * main.c (log_working_directory): Add newlines to printf()s.
2257 * README.cvs: Add a note to ignore warnings during autoreconf.
2259 * maintMakefile (po_repo): Set a new URL for PO file updates.
2260 (get-config/config.guess get-config/config.sub): Get these files
2261 from the Savannah config project instead of ftp.gnu.org.
2263 2003-10-05 Paul Eggert <eggert@twinsun.com>
2265 * main.c (main): Avoid potential subscript error if environ has
2268 2003-08-22 Paul D. Smith <psmith@gnu.org>
2270 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2271 systems which don't yet implement the C89 standard :-/.
2273 2003-07-18 Paul D. Smith <psmith@gnu.org>
2275 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2276 [WINDOWS32]: Initialize hash.
2278 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2280 * dir.c (read_dirstream): Provide a workaround for broken versions of
2281 the MinGW dirent structure.
2283 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2285 * w32/include/dirent.h: Add __MINGW32__ filter.
2287 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2289 * make.h: Add global declaration of *make_host.
2290 * main.c (print_usage): Remove local declaration of *make_host.
2291 (print_version): Display "This program built for ..." after Copyright
2294 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2296 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2297 execution of "makeinfo --html make.texi".
2299 2003-04-30 Paul D. Smith <psmith@gnu.org>
2301 * build.template: Make some changes to maybe allow this script to
2302 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2304 * README.OS2.template: New file for OS/2 support. Original
2305 contributed by Andreas Buening.
2306 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2309 2003-04-19 Paul D. Smith <psmith@gnu.org>
2311 Fix bug #1405: allow a target to match multiple pattern-specific
2314 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2315 variable.c, where they've always belonged.
2316 * rule.h: Move the prototypes and struct pattern_var as well.
2317 * variable.c (initialize_file_variables): Invoke
2318 lookup_pattern_var() in a loop, until no more matches are found.
2319 If a match is found, create a new variable set for the target's
2320 pattern variables. Then merge the contents of each matching
2321 pattern variable set into the target's pattern variable set.
2322 (lookup_pattern_var): Change this function to be usable
2323 in a loop. It takes a starting position: if NULL, start at the
2324 beginning; if non-NULL, start with the pattern variable after that
2325 position, and return the next matching pattern.
2326 (create_pattern_var): Create a unique instance of
2327 pattern-specific variables for every definition in the makefile.
2328 Don't combine the same pattern together. This allows us to
2329 process the variable handling properly even when the same pattern
2330 is used multiple times.
2331 (parse_variable_definition): New function: break out the parsing
2332 of a variable definition line from try_variable_definition.
2333 (try_variable_definition): Call parse_variable_definition to
2335 (print_variable_data_base): Print out pattern-specific variables.
2336 * variable.h (struct variable): Remember when a variable is
2337 conditional. Also remember its flavor.
2338 (struct pattern_var): Instead of keeping a variable set, we just
2339 keep a single variable for each pattern.
2340 * read.c (record_target_var): Each pattern variable contains only a
2341 single variable, not a set, so create it properly.
2342 * doc/make.texi (Pattern-specific): Document the new behavior.
2344 2003-04-17 Paul D. Smith <psmith@gnu.org>
2346 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2347 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2348 file/directory naming rules for VMS so I can't tell whether this
2351 2003-04-09 Paul D. Smith <psmith@gnu.org>
2353 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2354 DOS-style pathnames: backslash separators and drive specifiers.
2356 2003-03-28 Paul D. Smith <psmith@gnu.org>
2358 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2359 the intermediate flag on all targets. Fixes bug #2515.
2361 2003-03-24 Paul D. Smith <psmith@gnu.org>
2363 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2364 Upgrade to autoconf 2.57 and automake 1.7.3.
2366 * job.c: More OS/2 changes from Andreas Buening.
2368 * file.c (print_file): Fix variable initialization.
2371 * remake.c (notice_finished_file):
2373 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2374 some calls (like readdir()) return NULL in valid situations
2375 without resetting errno. Fixes bug #2846.
2377 2003-02-25 Paul D. Smith <psmith@gnu.org>
2379 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2381 * job.c (_is_unixy_shell) [OS/2]: New function.
2382 Set default shell to /bin/sh.
2383 (reap_children): Close the job_rfd pipe here since we don't use a
2385 (set_child_handler_action_flags): define this to empty on OS/2.
2386 (start_job_command): Close the jobserver pipe and use
2387 child_execute_job() instead of fork/exec.
2388 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2389 rather than exec'ing, then reconfigure stdin/stdout.
2390 (exec_command): Rewrite to use spawn instead of exec. Return the
2393 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2394 in DOS. Handle the TEMP environment variable as in DOS. Don't
2395 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2396 use -j in DOS mode. Use child_execute_job() instead of
2399 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2402 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2403 prototypes that return values.
2405 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2407 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2408 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2410 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2413 2003-02-24 Paul D. Smith <psmith@gnu.org>
2415 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2416 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2417 (child_execute_job) [VMS]: Handle error status properly.
2418 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2420 * function.c (func_shell): Use EINTRLOOP() while reading from the
2421 subshell pipe (Fixes bug #2502).
2422 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2424 * main.c (main): Ditto.
2426 2003-01-30 Paul D. Smith <psmith@gnu.org>
2428 * read.c (eval): eval() was not fully reentrant, because the
2429 collapsed buffer was static. Change it to be an automatic
2430 variable so that eval() can be invoked recursively.
2432 (eval): Apply patch # 1022: fix memory reference error on long
2433 target-specific variable lines.
2434 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2436 * function.c (check_numeric): Combine the is_numeric() function
2437 into this function, since it's only called from one place.
2438 Constify this function. Have it print the incorrect string in the
2439 error message. Fixes bug #2407.
2440 (strip_whitespace): Constify.
2441 (func_if): Constify.
2442 * expand.c (expand_argument): Constify.
2444 2003-01-29 Paul D. Smith <psmith@gnu.org>
2446 Fix bug # 2169, also reported by other people on various systems.
2448 * make.h: Some systems, such as Solaris and PTX, do not fully
2449 implement POSIX-compliant SA_RESTART functionality; important
2450 system calls like stat() and readdir() can still fail with EINTR
2451 even if SA_RESTART has been set on the signal handler. So,
2452 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2453 EINTR for system calls which return -1 or 0 (NULL), respectively,
2455 Also, remove the old atomic_stat()/atomic_readdir() and
2456 HAVE_BROKEN_RESTART handling.
2458 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2460 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2461 * remake.c (touch_file): Ditto.
2463 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2464 * read.c (construct_include_path): Ditto.
2465 * remake.c (name_mtime): Ditto.
2466 * vpath.c (selective_vpath_search): Ditto.
2467 * dir.c (find_directory): Ditto.
2468 (local_stat): Ditto.
2469 (find_directory): Use ENULLLOOP() to wrap opendir().
2470 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2472 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2473 atomic_readdir() handling.
2475 2003-01-22 Paul D. Smith <psmith@gnu.org>
2477 * function.c (func_call): Fix Bug #1744. If we're inside a
2478 recursive invocation of $(call ...), mask any of the outer
2479 invocation's arguments that aren't used by this one, so that this
2480 invocation doesn't "inherit" them accidentally.
2482 2002-12-05 Paul D. Smith <psmith@gnu.org>
2484 * function.c (subst_expand): Valery Khamenia reported a
2485 pathological performance hit when doing substitutions on very
2486 large values with lots of words: turns out we were invoking
2487 strlen() a ridiculous number of times. Instead of having each
2488 call to sindex() call strlen() again, keep track of how much of
2489 the text we've seen and pass the length to sindex().
2491 2002-11-19 Paul D. Smith <psmith@gnu.org>
2493 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2496 2002-11-16 Paul D. Smith <psmith@gnu.org>
2498 * NMakefile.template (OBJS): Add hash.c object file.
2499 * SMakefile.template (srcs): Ditto.
2500 * Makefile.ami (objs): Ditto.
2501 * build_w32.bat: Ditto.
2503 * Makefile.DOS.template: Remove extra dependencies.
2505 2002-10-25 Paul D. Smith <psmith@gnu.org>
2507 * expand.c (install_variable_buffer): New function. Install a new
2508 variable_buffer context and return the previous one.
2509 (restore_variable_buffer): New function. Free the current
2510 variable_buffer context and put a previously saved one back.
2511 * variable.h: Prototypes for {install,restore}_variable_buffer.
2512 * function.c (func_eval): Push a new variable_buffer context
2513 before we eval, then restore the old one when we're done.
2516 * read.c (install_conditionals): New function. Install a new
2517 conditional context and return the previous one.
2518 (restore_conditionals): New function. Free the current
2519 conditional context and put a previously saved one back.
2520 (eval): Use the {install,restore}_conditionals for "include"
2522 (eval_buffer): Use {install,restore}_conditionals to preserve the
2523 present conditional state before we evaluate the buffer.
2526 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2528 (Recursion): Add a variable index entry for CURDIR.
2530 * README.cvs: Update to appropriate versions.
2531 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2532 don't need to copy loadavg.c: automake is smart enough to create
2533 it for me. Still have a bug in automake related to ansi2knr tho.
2535 2002-10-14 Paul D. Smith <psmith@gnu.org>
2537 * remake.c (notice_finished_file): Only touch targets if they have
2538 at least one command (as per POSIX). Resolve Bug #1418.
2540 * *.c: Convert to using ANSI C-style function definitions.
2541 * Makefile.am: Enable the ansi2knr feature of automake.
2542 * configure.in: ditto.
2544 2002-10-13 Paul D. Smith <psmith@gnu.org>
2546 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2547 for automatic variable values like $^, etc. In the case of very
2548 large lists of prerequisites this causes problems. Instead reuse
2549 a static buffer (resizeable) for each variable.
2551 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2552 target-specific variable definitions. Check for it and set an
2554 (record_target_var): Set the export field to v_export if the
2555 "exported" flag is set.
2556 * doc/make.texi (Target-specific): Document the ability to use
2559 * doc/make.texi: Change the name of the section on automatic
2560 variables from "Automatic" to "Automatic Variables". Added text
2561 clarifying the scope of automatic variables.
2563 2002-10-04 Paul D. Smith <psmith@gnu.org>
2565 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2567 (record_files): Ditto.
2569 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2570 the search for the '=' to only within the enclosing parens.
2572 2002-10-03 Paul D. Smith <psmith@gnu.org>
2574 Version 3.80 released.
2576 * dir.c: Change hash functions to use K&R function definition style.
2577 * function.c: Ditto.
2579 * variable.c: Ditto.
2581 Update to automake 1.7.
2583 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2584 (pdf): Remove this target as automake now provides one.
2586 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2588 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2590 * makefile.com: Updates for GNU make 3.80.
2591 * makefile.vms: Ditto.
2593 2002-09-23 Paul D. Smith <psmith@gnu.org>
2595 * read.c (enum make_word_type): Remove w_comment.
2596 (get_next_mword): Don't treat comment characters as special; where
2597 this function is used we will never see a comment (it's stripped
2598 before we get here) and treating comments specially means that
2599 targets like "foo\#bar" aren't handled properly.
2601 2002-09-18 Paul D. Smith <psmith@gnu.org>
2603 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2605 * read.c (eval): Expansion of arguments to export/unexport was
2606 ignoring all arguments after the first one. Change the algorithm
2607 to expand the whole line once, then parse the results.

2611 Fix Bug #940 (plus another bug I found while looking at this):
2613 * read.c (record_target_var): enter_file() will add a new entry if
2614 it's a double-colon target: we don't want to do that in this
2615 situation. Invoke lookup_file() and only enter_file() if it does
2616 not already exist. If the file we get back is a double-colon then
2617 add this variable to the "root" double-colon target.
2619 * variable.c (initialize_file_variables): If this file is a
2620 double-colon target but is not the "root" target, then initialize
2621 the root and make the root's variable list the parent of our
2624 2002-09-13 Paul D. Smith <psmith@gnu.org>
2626 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2628 * hash.c (round_up_2): Get rid of a warning.
2630 2002-09-12 Paul D. Smith <psmith@gnu.org>
2632 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2633 so it doesn't complain about getloadavg.c.
2635 * commands.c (set_file_variables): Make sure we always alloca() at
2636 least 1 character for the value of $? (for '\0').
2638 2002-09-11 Paul D. Smith <psmith@gnu.org>
2640 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2641 macro to use RESULT instead of the incorrect _RESULT_.
2643 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2644 and atomic_readdir(). We need to #include dirent.h to get this to
2646 * misc.c (atomic_readdir): Fix typos.
2648 2002-09-10 Paul D. Smith <psmith@gnu.org>
2650 * read.c (eval): Expand variable lists given to export and
2651 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2652 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2654 * doc/make.texi (Variables/Recursion): Document this.
2655 (Conditional Syntax): And here.
2657 2002-09-09 Paul D. Smith <psmith@gnu.org>
2659 * configure.in: Check for memmove().
2661 2002-09-07 Paul D. Smith <psmith@gnu.org>
2663 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2664 Michael Sterrett <msterret@coat.com> reports that while it has
2665 SA_RESTART, it does not work properly.
2667 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2668 that invokes stat() and loops to do it again if it returns EINTR.
2669 (atomic_readdir): Ditto, with readdir().
2671 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2672 and readdir() to atomic_stat() and atomic_readdir().
2674 2002-09-04 Paul D. Smith <psmith@gnu.org>
2676 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2677 reports that GNU make sometimes doesn't recognize that targets can
2678 be made, when directories can be created as prerequisites. He
2679 reports that changing the order of predicates in the DEP->changed
2680 flag test so that lookup_file() is always performed, solves this
2683 2002-08-08 Paul D. Smith <psmith@gnu.org>
2685 * configure.in: Require a newer version of gettext.
2687 * misc.c (perror_with_name): Translate the format string (for
2688 right-to-left language support).
2689 (pfatal_with_name): Ditto.
2691 * main.c: Create a static array of strings to store the usage
2692 text. This is done to facilitate translations.

2695 (print_usage): Print each element of the usage array.
2697 * hash.c: Change function definitions to be K&R style.
2699 2002-08-02 Paul D. Smith <psmith@gnu.org>
2701 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2702 this one because it's too hard to get right. We'll look at it for
2704 * main.c (main): Don't create the .TARGETS variable.
2705 * variable.c (handle_special_var): Don't handle .TARGETS.
2707 2002-08-01 Paul D. Smith <psmith@gnu.org>
2709 * main.c (switches): Add a new option, -B (--always-make). If
2710 specified, make will rebuild all targets that it encounters even
2711 if they don't appear to be out of date.
2712 (always_make_flag): New flag.
2713 * make.h: Extern always_make_flag.
2714 * remake.c (update_file_1): Check always_make_flag; if it's set we
2715 will always rebuild any target we can, even if none of its
2716 prerequisites are newer.
2719 * doc/make.texi (Shell Function): Make it clear that make
2720 variables marked as "export" are not passed to instances of the
2723 Add new introspection variable .VARIABLES and .TARGETS.
2725 * variable.c (handle_special_var): New function. If the variable
2726 reference passed in is "special" (.VARIABLES or .TARGETS),
2727 calculate the new value if necessary. .VARIABLES is handled here:
2728 walk through the hash of defined variables and construct a value
2729 which is a list of the names. .TARGETS is handled by
2730 build_target_list().
2731 (lookup_variable): Invoke handle_special_var().
2732 * file.c (build_target_list): Walk through the hask of known files
2733 and construct a list of the names of all the ones marked as
2735 * main.c (main): Initialize them to empty (and as simple variables).
2736 * doc/make.texi (Special Variables): Document them.
2737 * NEWS: Mention them.
2739 * variable.h (struct variable): Add a new flag "exportable" which
2740 is true if the variable name is valid for export.
2741 * variable.c (define_variable_in_set): Set "exportable" when a new
2742 variable is defined.
2743 (target_environment): Use the "exportable" flag instead of
2744 re-checking the name here... an efficiency improvement.
2746 2002-07-31 Paul D. Smith <psmith@gnu.org>
2748 * config.h-vms.template: Updates to build on VMS. Thanks to
2749 Brian_Benning@aksteel.com for helping verify the build.
2750 * makefile.com: Build the new hash.c file.
2751 * hash.h: Use strcpmi(), not stricmp(), in the
2752 HAVE_CASE_INSENSITIVE_FS case.
2754 2002-07-30 Paul D. Smith <psmith@gnu.org>
2756 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2757 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2758 Reported by <Brian_Benning@aksteel.com>.
2760 2002-07-10 Paul D. Smith <psmith@gnu.org>
2762 * variable.c (pop_variable_scope): Remove variable made unused by
2763 new hash infrastructure.
2764 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2765 comparisons as well as name comparisons.
2766 * variable.h: Add a prototype for new hash_init_function_table().
2767 * file.c (lookup_file): Remove variables made unused by new hash
2769 * dir.c (directory_contents_hash_2): Missing return of hash value.
2770 (dir_contents_file_exists_p): Remove variables made unused by new
2771 hash infrastructure.
2774 Installed Greg McGary's integration of the hash functions from the
2775 GNU id-utils package:
2777 2002-07-10 Greg McGary <greg@mcgary.org>
2779 * scripts/functions/filter-out: Add literals to to the
2780 pattern space in order to add complexity, and trigger
2781 use of an internal hash table. Fix documentation strings.
2782 * scripts/targets/INTERMEDIATE: Reverse order of files
2783 passed to expected `rm' command.
2785 2002-07-10 Greg McGary <greg@mcgary.org>

2877 2002-07-10 Paul D. Smith <psmith@gnu.org>
2879 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2880 prerequisite list. A real SysV make will expand the entire
2881 prerequisites list _twice_: we don't do that as it's a big
2882 backward-compatibility problem. We only replace those specific
2885 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2886 references left in the list of prerequisites. Check for .POSIX as
2887 we record targets, so we can disable non-POSIX behavior while
2888 reading makefiles as well as running them.
2889 (eval): Check the prerequisite list to see if we have anything
2890 that looks like a SysV prerequisite variable reference.
2892 2002-07-09 Paul D. Smith <psmith@gnu.org>
2894 * doc/make.texi (Prerequisite Types): Add a new section describing
2895 order-only prerequisites.
2897 * read.c (uniquize_deps): If we have the same file as both a
2898 normal and order-only prereq, get rid of the order-only prereq,
2899 since the normal one supersedes it.
2901 2002-07-08 Paul D. Smith <psmith@gnu.org>
2903 * AUTHORS: Added Greg McGary to the AUTHORS file.
2904 * NEWS: Blurbed order-only prerequisites.
2905 * file.c (print_file): Show order-only deps properly when printing
2908 * maintMakefile: Add "update" targets for wget'ing the latest
2909 versions of various external files. Taken from Makefile.maint in
2912 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2913 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2915 2002-07-07 Paul D. Smith <psmith@gnu.org>
2917 * po/*.po: Remove. We'll use wget to retrieve them at release
2920 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2921 rather than a shell you get an exception. Make sure we look up
2922 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2924 * remake.c (notice_finished_file): Fix handling of -t flag.
2925 Patch provided by Henning Makholm <henning@makholm.net>.
2927 * implicit.c (pattern_search): Some systems apparently run short
2928 of stack space, and using alloca() in this function caused an
2929 overrun. I modified it to use xmalloc() on the two variables
2930 which seemed like they might get large. Fixes Bug #476.
2932 * main.c (print_version): Update copyright notice to conform with
2934 (print_usage): Update help output.
2936 * function.c (func_eval): Create a new make function, $(eval
2937 ...). Expand the arguments, put them into a buffer, then invoke
2938 eval_buffer() on the resulting string.
2939 (func_quote): Create a new function, $(quote VARNAME). Inserts
2940 the value of the variable VARNAME without expanding it any
2943 * read.c (struct ebuffer): Change the linebuffer structure to an
2944 "eval buffer", which can be either a file or a buffer.
2945 (eval_makefile): Move the code in the old read_makefile() which
2946 located a makefile into here: create a struct ebuffer with that
2947 information. Have it invoke the new function eval() with that
2949 (eval_buffer): Create a new function that creates a struct ebuffer
2950 that holds a string buffer instead of a file. Have it invoke
2951 eval() with that ebuffer.
2952 (eval): New function that contains the guts of the old
2953 read_makefile() function: this function parses makefiles. Obtains
2954 data to parse from the provided ebuffer. Some modifications to
2955 make the flow of the function cleaner and clearer. Still could
2956 use some work here...
2957 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2958 contents of the define/endef variable from the ebuffer.
2959 (readstring): Read the next line from a string-style ebuffer.
2960 (readline): Read the next line from an ebuffer. If it's a string
2961 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2964 * dep.h (eval_buffer): Prototype eval_buffer();
2966 * variable.c (do_variable_definition): Make sure that all
2967 non-target-specific variables are registered in the global set.
2968 If we're invoked from an $(eval ...) we might be inside a $(call
2969 ...) or other function which has pushed a variable scope; we still
2970 want to define our variables from evaluated makefile code in the
2973 2002-07-03 Greg McGary <greg@mcgary.org>
2975 * dep.h (struct dep) [ignore_mtime]: New member.
2976 [changed]: convert to a bitfield.
2977 * implicit.c (pattern_search): Zero ignore_mtime.
2978 * main.c (main, handle_non_switch_argument): Likewise.
2979 * rule.c (convert_suffix_rule): Likewise.
2980 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2981 (read_makefile): Parse '|' in prerequisite list.
2982 (uniquize_deps): Consider ignore_mtime when comparing deps.
2983 * remake.c (update_file_1, check_dep): Don't force remake for
2984 dependencies that have d->ignore_mtime.
2985 * commands.c (FILE_LIST_SEPARATOR): New constant.
2986 (set_file_variables): Don't include a
2987 prerequisite in $+, $^ or $? if d->ignore_mtime.
2990 2002-06-18 Paul D. Smith <psmith@gnu.org>
2992 * make.texinfo: Updates for next revision. New date/rev/etc.
2993 Recreate all Info menus. Change license on the manual to the GNU
2994 Free Documentation License. A number of typos.
2995 (Variables Simplify): Don't use "-" before it's defined.
2996 (Automatic Prerequisites): Rewrite the target example to work
2997 properly if the compile fails. Remove incorrect comments about
2998 how "set -e" behaves.
2999 (Text Functions): Move the "word", "wordlist", "words", and
3000 "firstword" functions here, from "File Name Functions".
3001 * make-stds.texi: Update from latest GNU version.
3002 * fdl.texi: (created) Import the latest GNU version.
3004 2002-06-06 Paul D. Smith <psmith@gnu.org>
3006 * variable.c (do_variable_definition): New function: extract the
3007 part of try_variable_definition() that actually sets the value
3008 into a separate function.
3009 (try_variable_definition): Call do_variable_definition() after
3010 parsing the variable definition string.
3011 (define_variable_in_set): Make the name argument const.
3013 * variable.h (enum variable_flavor): Make public.
3014 (do_variable_definition): Create prototype.
3016 * read.c (read_all_makefiles): Create a new built-in variable,
3018 (read_makefile): Add each makefile read in to this variable value.
3020 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3022 * Makefile.DOS.template: Tweak according to changes in the
3023 distribution. Add back the dependencies of *.o files.
3025 * configh.dos.template: Synchronize with config.h.in.
3027 2002-05-09 Paul D. Smith <psmith@gnu.org>
3029 * file.c (file_timestamp_now): Use K&R function declaration.
3031 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3032 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3033 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3034 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3035 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3036 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3037 nlist.n_name is a pointer rather than an array.
3039 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3040 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3041 * configure.in: Use it instead of the old version.
3043 * main.c (main): Prefer setvbuf() to setlinebuf().
3045 2002-05-08 Paul D. Smith <psmith@gnu.org>
3047 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3048 (loadavg_LDADD): Ditto.
3050 2002-04-29 Paul D. Smith <psmith@gnu.org>
3052 * expand.c (recursively_expand_for_file): Rename
3053 recursively_expand() to recursively_expand_for_file() and provide
3054 an extra argument, struct file. If the argument is provided, set
3055 the variable scope to that of the file before expanding.
3056 * variable.h (recursively_expand): Make this a macro that invokes
3057 recursively_expand_for_file() with a NULL file pointer.
3058 * variable.c (target_environment): Call the renamed function and
3059 provide the current file context.
3060 Fixes Debian bug #144306.
3062 2002-04-28 Paul D. Smith <psmith@gnu.org>
3064 Allow $(call ...) user-defined variables to be self-referencing
3065 without throwing an error. Allows implementation of transitive
3066 closures, among other possibly useful things.
3067 Requested by: Philip Guenther <guenther@sendmail.com>
3069 * variable.h (struct variable): Add a new field: exp_count, and
3070 new macros to hold its size and maximum value.
3071 (warn_undefined): Make this a macro.
3072 * variable.c (define_variable_in_set): Initialize it.
3073 * expand.c (recursively_expand): If we detect recursive expansion
3074 of a variable, check the exp_count field. If it's greater than 0
3075 allow the recursion and decrement the count.
3076 (warn_undefined): Remove this (now a macro in variable.h).
3077 * function.c (func_call): Before we expand the user-defined
3078 function, modify its exp_count field to contain the maximum
3079 number of recursive calls we'll allow. After the call, reset it
3082 2002-04-21 Paul D. Smith <psmith@gnu.org>
3084 Modified to use latest autoconf (2.53), automake (1.6.1), and
3085 gettext (0.11.1). We're using gettext's new "external" support,
3086 to avoid including libintl source with GNU make.
3088 * README.cvs: New file. Explain how to build GNU make from CVS.
3090 * configure.in: Modify checking for the system glob library.
3091 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3092 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3093 etc. will manage it correctly). Set an automake conditional
3094 USE_LOCAL_GLOB to decide whether to compile the glob library.
3096 * getloadavg.c (main): Include make.h in the "TEST" program to
3099 * Makefile.am: Remove special rules for loadavg. Replace them
3100 with Automake capabilities for building extra programs.
3102 * signame.c: This file does nothing if the system provide
3103 strsignal(). If not, it implements strsignal(). If the system
3104 doesn't define sys_siglist, then we make our own; otherwise we use
3106 * signame.h: Removed.
3108 * main.c (main): No need to invoke signame_init(). Update copyright.
3110 * ABOUT-NLS: Removed.
3111 * gettext.c: Removed.
3112 * gettext.h: Get a simplified copy from the gettext package.
3114 * i18n/*.po: Moved to po/.
3117 * config/*: Created. Contains package configuration helper files.
3118 * config.guess, config.sub: Moved to config directory.
3120 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3121 Rework to use new-style autoconf features. Use the "external"
3122 mode for gettext. Make the build.sh config file conditional on
3123 whether build.sh.in exists, to avoid autoconf errors.
3124 * acinclude.m4: Removed almost all macros as being obsolete.
3125 Rewrote remaining macros to use AC_DEFINE.
3126 * acconfig.h: Removed.
3128 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3129 conditional to handle customs support. Remove special handling
3132 2002-04-20 Paul D. Smith <psmith@gnu.org>
3134 * function.c (func_call): Don't mark the argument variables $1,
3135 etc. as recursive. They've already been fully expanded so
3136 there's no need to do it again, and doing so strips escaped $'s.
3137 Reported by Sebastian Glita <glseba@yahoo.com>.
3139 * remake.c (notice_finished_file): Walk through double-colon
3140 entries via the prev field, not the next field!
3141 Reported by Greg McGary <greg@mcgary.org>.
3143 * main.c (main): If the user specifies -q and asks for a specific
3144 target which is a makefile, we got an assert. In that case it
3145 turns out we should continue normally instead.
3147 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3149 * i18n/he.po: Installed a new translation.
3151 2002-01-07 Paul D. Smith <psmith@gnu.org>
3153 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3155 2001-12-04 Paul D. Smith <psmith@gnu.org>
3157 * i18n/ja.po: Installed an updated translation.
3159 2001-09-06 Paul Eggert <eggert@twinsun.com>
3161 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3162 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3164 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3166 (main): Get rid of any avoidable limit on stack size.
3168 2001-09-04 Paul D. Smith <psmith@gnu.org>
3170 * i18n/da.po: Installed an updated translation.
3172 2001-08-03 Paul D. Smith <psmith@gnu.org>
3174 * i18n/fr.po: Installed an updated translation.
3175 Resolves Debian bug #106720.
3177 2001-06-13 Paul D. Smith <psmith@gnu.org>
3179 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3182 2001-06-11 Paul D. Smith <psmith@gnu.org>
3184 * i18n/ko.po: Installed a new translation.
3186 2001-05-06 Paul D. Smith <psmith@gnu.org>
3188 Modify the EINTR handling.
3190 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3191 the way in which we manage the file descriptor/signal handler race
3192 trap to be more efficient.
3194 2001-05-06 Paul Eggert <eggert@twinsun.com>
3196 Restart almost all system calls that are interrupted, instead
3197 of worrying about EINTR. The lone exception is the read() for
3200 * configure.in (HAVE_SA_RESTART): New macro.
3201 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3202 * main.c (main): Use SA_RESTART instead of the old,
3203 nonstandard SA_INTERRUPT.
3205 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3206 * main.c (bsd_signal): New function or macro,
3207 if the implementation doesn't supply it.
3208 (The bsd_signal function will be in POSIX 1003.1-200x.)
3209 (HANDLESIG): Remove.
3210 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3212 * make.h (EINTR_SET): Remove.
3213 (SA_RESTART): New macro.
3215 * arscan.c (ar_member_touch): Don't worry about EINTR.
3216 * function.c (func_shell): Likewise.
3217 * job.c (reap_children, free_child, new_job): Likewise.
3218 * main.c (main): Likewise.
3219 * remake.c (touch_file, name_mtime): Likewise.
3221 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3222 if fstat failed with errno!=EINTR, the error was ignored.
3224 * job.c (set_child_handler_action_flags): New function.
3225 (new_job): Use it to temporarily clear the SIGCHLD action flags
3226 while reading the token.
3228 2001-05-02 Paul D. Smith <psmith@gnu.org>
3230 * job.c (start_job_command): Don't add define/endef per-line flags
3231 to the top-level flags setting.
3233 2001-04-03 Paul D. Smith <psmith@gnu.org>
3235 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3236 bit on error, so check for odd return values, not non-0 return
3238 (VMS_get_member_info): Calculate the timezone differences correctly.
3239 Reported by John Fowler <jfowler@nyx.net>.
3242 2001-03-14 Paul D. Smith <psmith@gnu.org>
3244 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3245 value before invoking define_variable().
3246 Reported by John Fowler <jfowler@nyx.net>.
3248 2001-02-07 Paul D. Smith <psmith@gnu.org>
3250 * read.c (record_target_var): If we reset the variable due to a
3251 command-line variable setting overriding it, turn off the "append"
3254 2001-01-17 Paul D. Smith <psmith@gnu.org>
3256 * variable.c (lookup_variable) [VMS]: When getting values from the
3257 environment, allocate enough space for the _value_ plus escapes,
3258 not enough space for the name plus escapes :-/.
3259 Reported by John Fowler <jfowler@nyx.net>.
3261 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3262 warnings that make generates, so it doesn't look like an error.
3263 Reported by Karl Berry <karl@gnu.org>.
3266 Fix for PR/2020: Rework appended target-specific variables. I'm
3267 fairly confident this algorithm is finally correct.
3269 * expand.c (allocated_variable_append): Rewrite. Instead of
3270 expanding each appended variable then adding all the expanded
3271 strings together, we append all the unexpanded values going up
3272 through the variable set contexts, then expand the final result.
3273 This behaves just like non-target-specific appended variable
3274 values, while the old way didn't in various corner cases.
3275 (variable_append): New function: recursively append the unexpanded
3276 value of a variable, walking from the outermost variable scope to
3278 * variable.c (lookup_variable): Remove the code that looked up the
3279 variable set list if the found variable was "append". We don't
3281 (lookup_variable_in_set): Make this non-static so we can use it
3283 (try_variable_definition): Use lookup_variable_in_set() rather
3284 than faking out current_variable_set_list by hand (cleanup).
3285 * variable.h: Add a prototype for the now non-static
3286 lookup_variable_in_set().
3288 2000-11-17 Paul D. Smith <psmith@gnu.org>
3290 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3291 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3292 before throwing a fit.
3294 2000-11-17 Paul D. Smith <psmith@gnu.org>
3296 * read.c (readline): CRLF calculations had a hole, if you hit the
3297 buffer grow scenario just right. Reworked the algorithm to avoid
3298 the need for len or lastlen at all. Problem description with
3299 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3301 2000-10-24 Paul D. Smith <psmith@gnu.org>
3303 * gettext.c (SWAP): Declare this with the prototype, otherwise
3304 some systems don't work (non-32-bit? Reported for Cray T3E).
3305 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3307 2000-10-05 Paul D. Smith <psmith@gnu.org>
3309 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3310 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3312 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3314 2000-09-22 Paul D. Smith <psmith@gnu.org>
3316 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3317 parts of the real gettext.h here, and we expect to really include
3318 the real gettext.h later. If we keep this #define, it's ignored.
3320 2000-09-21 Paul D. Smith <psmith@gnu.org>
3322 * main.c (log_working_directory): Rework the text to use complete
3323 sentences, to make life simpler for the translators.
3325 2000-08-29 Paul D. Smith <psmith@gnu.org>
3327 * file.c (remove_intermediates): Print a debug message before we
3328 remove intermediate files, so the user (if she uses -d) knows
3331 2000-08-21 Paul D. Smith <psmith@gnu.org>
3333 * variable.c (try_variable_definition): Change how we handle
3334 target-specific append variable defns: instead of just setting the
3335 value, expand it as an append _but_ only within the current
3336 target's context. Otherwise we lose all but the last value if the
3337 variable is appended more than once within the current target
3338 context. Fixes PR/1831.
3340 2000-08-16 Paul D. Smith <psmith@gnu.org>
3342 * function.c (func_shell): Nul-terminate the buffer before
3343 printing an exec error message (just in case it's not!).
3344 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3346 2000-07-25 Paul D. Smith <psmith@gnu.org>
3348 * job.c (construct_command_argv_internal): Add "~" to the list of
3349 sh_chars[] which disallow optimizing out the shell call.
3351 2000-07-23 Paul Eggert <eggert@twinsun.com>
3353 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3354 supersedes --disable-nsec-timestamps.
3355 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3356 * README: Remove --disable-nsec-timestamps.
3358 * filedef.h (struct file.low_resolution_time): New member.
3359 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3360 * remake.c (update_file_1):
3361 Avoid spurious rebuilds due to low resolution time stamps,
3362 generalizing the earlier code that applied only to archive members.
3363 (f_mtime): Archive members always have low resolution time stamps.
3365 * configure.in: Remove --disable-nsec-timestamps, as this has
3366 been superseded by .LOW_RESOLUTION_TIME.
3368 2000-07-23 Paul Eggert <eggert@twinsun.com>
3370 * configure.in (enable_nsec_timestamps): Renamed from
3371 make_cv_nsec_timestamps, since enable/disable options
3372 shouldn't be cached.
3374 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3375 and Paul Eggert <eggert@twinsun.com>
3377 * file.c (file_timestamp_now):
3378 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3379 so that clock_gettime is not linked unless needed.
3381 * filedef.h (FILE_TIMESTAMP_HI_RES):
3382 Remove definition; "configure" now does this.
3384 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3385 to before high resolution file timestamp check,
3386 since that check now uses uintmax_t.
3387 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3388 high resolution file timestamps.
3389 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3390 so that we don't link in clock_gettime unnecessarily.
3392 2000-07-17 Paul D. Smith <psmith@gnu.org>
3394 * i18n/ja.po: New version of the translation file.
3396 2000-07-07 Paul D. Smith <psmith@gnu.org>
3398 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3399 the offset calculation.
3400 (name_mtime): Replace EINTR test with EINTR_SET macro.
3402 2000-07-07 Paul Eggert <eggert@twinsun.com>
3406 * remake.c (update_file_1):
3407 Avoid spurious rebuilds of archive members due to their
3408 timestamp resolution being only one second.
3409 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3410 the clock's resolution being lower than file timestamps'.
3411 When warning about future timestamps, report only the discrepancy,
3412 not the absolute value of the timestamp and the current time.
3414 * file.c (file_timestamp_now): New arg RESOLUTION.
3415 * filedef.h (file_timestamp_now): Likewise.
3416 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3418 2000-07-05 Paul D. Smith <psmith@gnu.org>
3420 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3421 to listp. Fixes PR/1793.
3423 2000-06-26 Paul Eggert <eggert@twinsun.com>
3425 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3427 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3429 * remake.c (f_mtime): Remove unused var memtime.
3431 2000-06-25 Martin Buchholz <martin@xemacs.org>
3433 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3434 Ran spell-check on make.texinfo.
3436 2000-06-23 Paul D. Smith <psmith@gnu.org>
3438 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3439 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3440 * make.h: Define these macros.
3442 * Version 3.79.1 released.
3444 * configure.in: Add a new option, --disable-nsec-timestamps, to
3445 avoid using sub-second timestamps on systems that support it. It
3446 can lead to problems, e.g. if your makefile relies on "cp -p".
3447 * README.template: Document the issue with "cp -p".
3449 * config.guess, config.sub: Updated.
