3 * doc/make.texi (MAKEFILES Variable): Be explicit that files
4 included by MAKEFILES cannot give default goals.
5 * read.c (eval): If set_default is not set, pass the no-default-goal
6 value when we read included makefiles. Fixes Savannah bug #13401.
8 * ar.c (ar_name): Ensure that targets with empty parens aren't
9 considered archive member references: archive members must have a
10 non-empty "member" string. Fixes Savannah bug #18435.
12 * function.c (string_glob): Rely on multi_glob() to determine
13 whether files exist or not. Remove call to file_exists_p() which
14 is not always correct. Fixes Savannah bug #21231.
15 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
16 then only files that really exist will be returned.
17 * dep.h: Add new argument to multi_glob().
18 * rule.c (install_pattern_rule): Ditto.
19 * read.c (eval): Ditto.
20 * main.c (main): Ditto.
21 * implicit.c (pattern_search): Ditto.
22 * file.c (parse_prereqs): Ditto.
23 * default.c (set_default_suffixes): Ditto.
25 2009-06-09 Paul Smith <psmith@gnu.org>
27 * commands.c (set_file_variables): If always_make_flag is set,
28 always add the prereq to $?. Fixes Savannah bug #17825.
30 * remake.c (update_file_1): When rebuilding deps of FILE, also try
31 to rebuild the deps of all the also_make targets for that file.
32 Fixes Savannah bug #19108.
34 * implicit.c (pattern_search): Undo test for is_target, added by
35 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
36 Rule Search Algorithm". Fixes Savannah bug #17752.
38 * main.c (clean_jobserver): Clear the jobserver_fds options and
39 set job_slots to the default when we clean up.
40 (define_makeflags): Return the new MAKEFLAGS value.
41 (main): Reset MAKEFLAGS in the environment when we re-exec.
42 Fixes Savannah bug #18124.
44 2009-06-08 Paul Smith <psmith@gnu.org>
46 * read.c (eval): Collapse continuations post-semicolon on target-
47 specific variables. Fixes Savannah bug #17521.
49 2009-06-07 Paul Smith <psmith@gnu.org>
51 * job.c (reap_children): For older systems without waitpid() (are
52 there any of these left?) run wait(2) inside EINTRLOOP to handle
53 EINTR errors. Fixes Savannah bug #16401.
55 * (various): Debug message cleanup. Fixes Savannah bug #16469.
57 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
59 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
60 not the end, to catch second expansion $(eval ...) defining new
61 target/prereq relationships during snap_deps.
62 Fixes Savannah bug #24622.
64 * read.c (record_files): The second-expansion "f->updating" hack
65 was not completely correct: if assumed that the target with
66 commands always had prerequisites; if one didn't then the ordering
67 was messed up. Fixed for now to use f->updating to decide whether
68 to preserve the last element in the deps list... but this whole
69 area of constructing and reversing the deps list is too confusing
70 and needs to be reworked. Fixes Savannah bug #21198.
72 2009-06-06 Paul Smith <psmith@gnu.org>
74 * hash.c (hash_insert): Remove useless test for NULL.
75 Fixes Savannah bug #21823.
77 * make.h: Move SET_STACK_SIZE determination to make.h.
78 * main.c (main): New global variable, STACK_LIMIT, holds the
79 original stack limit when make was started.
80 * job.c (start_job_command): Reset the stack limit, if we changed it.
81 Fixes Savannah bug #22010.
83 * remake.c (check_dep): Only set the target's state to not-started
84 if it's not already running. Found this while testing -j10 builds
85 of glibc: various targets were being rebuilt multiple times.
86 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
89 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
90 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
93 2009-06-04 Paul Smith <psmith@gnu.org>
95 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
97 * maintMakefile: Modify access of config and gnulib Savannah
98 modules to use GIT instead of CVS.
100 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
101 Fixes Savannah bug #24655.
103 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
104 this can happen during some invocations of $(eval ...) for example.
105 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
107 2009-06-02 Paul Smith <psmith@gnu.org>
109 * configure.in: Check for fileno()
110 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
111 for the makefile file so invocations of $(shell ...) don't inherit it.
112 Fixes Savannah bug #24277.
114 2009-06-01 Paul Smith <psmith@gnu.org>
116 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
117 expansion was handled incorrectly. Rework the default goal
118 handling to save the variable only. Remove default_goal_file and
120 * read.c (eval): Check default_goal_var, not default_goal_name.
121 * read.c (record_target_var): Don't check default_goal_file here.
123 2009-05-31 Paul Smith <psmith@gnu.org>
125 * main.c (main): Expand the .DEFAULT_GOAL variable before using
126 it, and if the multi_glob() returns nothing (say it expanded to
127 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
129 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
130 $(and ..) to the reference. Fixes Savannah bug #25694.
132 * make.1: Be clear that some recipes will be executed even with -n.
133 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
135 * doc/make.texi (Override Directive): Make more clear how
136 overrides and appends interact.
137 Elucidates part of Savannah bug #26207.
139 * read.c (record_target_var): Don't reset the origin on
140 target-specific variables; try_variable_definition() will handle
141 this correctly. Fixes Savannah bug #26207.
143 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
144 Fixes Savannah bug #25712.
146 * implicit.c (pattern_search): Keep a pointer to the beginning of
147 the filename and save that instead of the constructed pointer.
148 Fixes Savannah bug #26593.
149 Patch by Mark Seaborn <mrs@mythic-beasts.com>
151 2009-05-30 Paul Smith <psmith@gnu.org>
153 * doc/make.texi (Multi-Line): Add a description of the new abilities
154 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
155 "command sequence" vs. "recipe" syntax.
156 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
157 after a define, to create variables with those flavors.
159 2009-05-25 Paul Smith <psmith@gnu.org>
161 Reworked the parser for variable assignments to allow multiple
162 modifiers, and in any order. Also allows variable and
163 prerequisites to be modifier names ('export', 'private', etc.)
165 * NEWS: Add notes about user-visible changes.
167 * read.c (struct vmodifiers): Remember what modifiers were seen.
168 (parse_var_assignment): New function to parse variable assignments.
169 (eval): Call the new function. Handle variable assignments earlier.
171 * variable.c (parse_variable_definition): Only parse; don't create var.
172 (assign_variable_definition): Call parse, then create the var.
174 2009-05-24 Paul Smith <psmith@gnu.org>
176 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
177 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
179 2009-03-14 Eli Zaretskii <eliz@gnu.org>
181 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
182 Fixes Savannah bug #25412.
184 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
185 prototype for xmalloc.
186 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
187 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
188 Loop over an array of extensions, instead of duplicating the same
189 code inline. Use SearchPath followed by CreateFile, instead of
190 the obsolete OpenFile. Fixes Savannah bug #17277.
191 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
192 to `find_file'. Fixes Savannah bug #25662.
194 2009-03-07 Eli Zaretskii <eliz@gnu.org>
196 * function.c (func_shell): Don't close pipedes[1] if it is -1.
197 Fixes Savannah bug #20495.
199 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
201 Introduce a new keyword "private" which applies to target-specific
202 variables and prevents their values from being inherited.
204 * variable.h (struct variable): Add private_var flag to each variable.
205 Add a flag to specify which list entry switches to the parent target.
206 * variable.c (define_variable_in_set): Initialize private_var flag.

210 * read.c (eval): Recognize the private keyword.
211 (record_target_var): Set private_var.
212 * doc/make.texi (Suppressing Inheritance): Add documentation.
214 2008-10-26 Paul Smith <psmith@gnu.org>
216 * configure.in: Check for strndup().

222 * read.c (eval, record_files): Ditto.
223 * variable.c (define_variable_in_set): Ditto.
225 2008-09-30 Eli Zaretskii <eliz@gnu.org>
227 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
230 * w32/subproc/build.bat (GCCBuild): Likewise.
232 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
234 * job.c (construct_command_argv_internal): Avoid extra backslash
235 in batch-mode Unixy shells. Under DB_JOBS, display the contents

240 * README.W32.template: Remove obsolete text about non-support for
241 -jN without Unixy shell. Remove obsolete text about not supplying
242 Visual Studio project files (we do supply them). Modify text to
243 prefer GCC builds to MSC builds.
245 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
247 * doc/make.texi (Empty Targets): Fix typo.
249 2008-03-27 Paul Smith <psmith@gnu.org>
251 Fix Savannah bug #22379:
252 * ar.c (ar_glob_match): Zero the allocated structure.
253 * read.c (parse_file_seq): Ditto.
255 2008-03-08 Brian Dessent <brian@dessent.net>
257 * maintMakefile: Update Translation Project location.
259 2008-01-26 Eli Zaretskii <eliz@gnu.org>
261 * variable.c (target_environment): Don't use shell_var if its
262 `value' field is NULL.
264 2007-12-22 Eli Zaretskii <eliz@gnu.org>
266 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
268 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
269 (TEXINFOS): Value changed to `doc/make.texi'.
270 (.SUFFIXES): Use .texi instead of .texinfo.
271 (make.info, make.dvi): Depend on doc/make.texi.
272 (.texi.info): New target, instead of ".texinfo.info". Change -I
273 switch to $(MAKEINFO) to look in doc/. Use --no-split.
274 (.texi): New target, instead of ".texinfo". Change -I switch to
275 $(MAKEINFO) to look in doc/. Use --no-split.
276 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
277 switch to $(MAKEINFO) to look in doc/.
278 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
279 "*.i[0-9][0-9]" (due to --no-split above).
280 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
281 (html, make_1.html): New targets.
282 (.PHONY): Add "html".
283 (.SUFFIXES): Add .html.
285 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
287 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
288 HAVE_DECL_SYS_SIGLIST.
290 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
291 build does not use child_execute_job.
293 * variable.c (define_automatic_variables) [__MSDOS__]: Always
294 export the SHELL environment variable to the child.
296 2007-12-22 Eli Zaretskii <eliz@gnu.org>
298 * config.h.W32: Include sys/types.h.

305 2007-11-04 Paul Smith <psmith@gnu.org>
307 * doc/make.texi: Convert references to "commands", "command
308 lines", and "command script" to "recipe".
310 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
313 2007-10-27 Bruno Haible <bruno@clisp.org>
315 * remake.c (f_mtime): Print time difference values between 100 and
316 ULONG_MAX in fixed-point notation rather than in exponention notation.
318 2007-10-12 Eli Zaretskii <eliz@gnu.org>
320 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
321 a more complex value than a simple shell: if it's not a default
322 shell now then expand it and see if is a default shell then.
324 2007-10-10 Eli Zaretskii <eliz@gnu.org>
326 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
327 pathnames, with const strings.
328 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
329 from the template (used for building from CVS, not a dist).
331 2007-10-10 Paul Smith <psmith@gnu.org>
333 * make.h: Add a prototype for w32_kill() (change suggested by
334 Yongwei Wu <wuyongwei@gmail.com>).
336 2007-09-21 Eli Zaretskii <eliz@gnu.org>
338 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
341 2007-09-12 Paul Smith <psmith@gnu.org>
343 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
344 Provided by Diego Biurrun <diego@biurrun.de>

346 Provided by Diego Biurrun <diego@biurrun.de>
348 2007-09-11 Paul Smith <psmith@gnu.org>
350 * doc/make.texi (Special Variables): Moved this into the "How to
351 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
352 (MAKEFILE_LIST) No longer a section; this was added into the
353 "Special Variables" section.
354 (Rule Introduction): Reference .RECIPEPREFIX.
355 (Simple Makefile): Ditto.
356 (Rule Syntax): Ditto.
357 (Command Syntax): Ditto.
358 (Error Messages): Ditto.
360 2007-09-10 Paul Smith <psmith@gnu.org>
362 * commands.c (print_commands): Don't print an extra line in the
363 command scripts. Prefix the command scripts with cmd_prefix, not \t.
365 * read.c (construct_include_path): Add the full string to the cache; we
366 were chopping the last char.
368 * NEWS: Announce the .RECIPEPREFIX special variable.
369 * variable.c (lookup_special_var): Rename from handle_special_var().
370 (lookup_variable): Call the new name.
371 (set_special_var): New function: handle setting of special variables.
372 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
373 (do_variable_definition): Call it.
374 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
375 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
376 * main.c (main): Create the .RECIPEPREFIX special variable.
377 * read.c (eval): Remove the cmd_prefix characters from the command
378 scripts here, so they're not stored in the commands array at all,
379 rather than waiting and stripping them out during command construction.
380 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
382 2007-08-15 Paul Smith <psmith@gnu.org>
384 * doc/make.texi (GNU Free Documentation License): The fdl.texi
385 file has had the section info removed, so add some to make.texi
386 before we include it.
388 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
390 * remake.c (check_dep): Reset the target state for intermediate
391 files. They might have been considered before but not updated
392 then (order-only for example) but they will be this time.
393 Fixes Savannah bug #'s 3330 and 15919.
395 2007-07-21 Eli Zaretskii <eliz@gnu.org>
397 Fix Savannah bug #20549:
398 * function.c (func_shell): Call construct_command_argv with zero
400 * job.c (construct_command_argv_internal): New argument FLAGS; all
402 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
404 * job.h (construct_command_argv_internal): Update prototype.
406 2007-07-13 Paul Smith <psmith@gnu.org>
408 * file.c (expand_deps): Use variable_buffer as the start of the
409 buffer, not the original pointer (in case it was reallocated).
410 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
411 Fixes Savannah bug #20452.
413 2007-07-04 Paul Smith <psmith@gnu.org>
415 * (ALL FILES): Update to GPLv3.
416 * (ALL FILES): Update copyright for 2007.
418 * main.c (print_version): Move the host type info to the second line.
420 2007-06-29 Thiemo Seufer <ths@mips.com>
422 * maintMakefile: Update Translation Project location.
424 2007-06-13 Paul Smith <psmith@gnu.org>
426 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
427 "Expansion of a deferred"
428 Fixes Savannah bug #20018.
430 * expand.c (variable_expand_for_file): Preserve the value of
431 reading_file rather than setting it to 0 at the end.
432 Fixes Savannah bug #20033.
434 2007-05-11 Paul Smith <psmith@gnu.org>
436 * job.c (new_job): Add debug info to specify where make found the
437 command script it is running to build a target.
438 Fixes Savannah bug #18617.
440 * default.c (default_suffixes,default_suffix_rules,default_variables):
441 Add support for Objective C. Fixes Savannah bug #16389.
442 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
444 * function.c (func_lastword): Initialize p.
446 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
447 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
448 Dave Korn <dave.korn@artimi.com>
450 2007-05-08 Paul Smith <psmith@gnu.org>
452 Fix Savannah bug #19656:
454 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
456 * make.h: Change all case-insensitive string compares to use
457 strcasecmp() (from POSIX). If we don't have that but do have one
458 of the others, define strcasecmp to be one of those instead. If
459 we don't have any, declare a prototype for our own version.
461 * misc.c (strcasecmp): Use this if we can't find any native
462 case-insensitive string comparison function.
463 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
464 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
466 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
467 strcasecmp() instead of stricmp().
468 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
469 instead of strcmpi().
470 * acinclude.m4: Remove the strcasecmp() check from here.
472 2007-03-21 Paul Smith <psmith@gnu.org>
474 * configure.in: Don't turn on case-insensitive file system support
475 if --disable-... is given. Fixes Savannah bug #19348.
477 2007-03-19 Paul Smith <psmith@gnu.org>
479 * ALL: Use the strcache for all file name strings, or other
480 strings which we will never free. The goal is to save memory by
481 avoiding duplicate copies of strings. However, at the moment this
482 doesn't save much memory in most situations: due to secondary
483 expansion we actually save prerequisite lists twice (once before
484 the secondary expansion, and then again after it's been parsed
485 into individual file names in the dep list). We will resolve this
486 in a future change, by doing the parsing up-front for targets
487 where secondary expansion is not set.
489 Moving things into the strcache also allows us to use const
490 pointers in many more places.
492 2007-01-03 Paul Smith <psmith@gnu.org>
494 * make.h (ENULLLOOP): Reset errno after each failed invocation of
495 the function, not just the first. Fixes Savannah bug #18680.
497 2006-11-18 Paul Smith <psmith@gnu.org>
499 * strcache.c (strcache_add_len): Don't allocate a new buffer
500 unless the string is not already nil-terminated. Technically this
501 is a violation of the standard, since we may be passed an array
502 that is not long enough to test one past. However, in make this
503 is never true since we only use nil-terminated strings or
506 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
508 * main.c: New global cmd_prefix, defaults to '\t'.
509 * job.c (construct_command_argv_internal): Use cmd_prefix instead
513 (dir_contents_file_exists_p): Check for an error return from
514 readdir(), just in case.
516 * commands.c: Constified.
517 * default.c: Constified.
518 * expand.c: Constified.
519 * function.c: Partial constification.
520 * variable.c: Partial constification.
521 * vmsify.c: Constification. Hard to test this but I hope I didn't
523 * vpath.c: Partial constification.
524 * w32/pathstuff.c: Partial constification.
526 2006-11-16 Eli Zaretskii <eliz@gnu.org>
528 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
529 backslashes and drive letters as absolute.
531 2006-10-22 Paul Smith <psmith@gnu.org>
533 * main.c (struct command_switch): Use const and void*.
535 2006-10-21 Paul Smith <psmith@gnu.org>
538 * arscan.c: Constified.
540 2006-09-30 Paul Smith <psmith@gnu.org>
542 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
543 point to lastword since the example was updated.

674 2006-03-23 Paul D. Smith <psmith@gnu.org>
676 * configure.in: Look for build.sh.in in $srcdir so it will be
677 built for remote configurations as well.

736 2006-03-09 Paul Smith <psmith@gnu.org>
738 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
739 listed non-existent files as changed. Turns out there's a bug in
740 the Linux kernel builds which means that this change causes
741 everything to rebuild every time. We will re-introduce this fix
742 in the next release, to give them time to fix their build system.
743 Fixes Savannah bug #16002.
744 Introduces Savannah bug #16051.
746 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

763 * commands.c (set_file_variables): Realloc, not malloc, the static
764 string values to avoid memory leaks.
766 * expand.c (recursively_expand_for_file): Only set reading_file to
767 an initialized value.
769 * implicit.c (pattern_search): We need to make a copy of the stem
770 if we get it from an intermediate dep, since those get freed.

786 prevent compiler warnings.
788 2006-02-18 Eli Zaretskii <eliz@gnu.org>
790 * job.c (construct_command_argv_internal): Don't create a temporary
791 script/batch file if we are under -n. Call _setmode to switch the
792 script file stream to text mode.

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

803 2006-02-15 Paul D. Smith <psmith@gnu.org>
805 Fix for Savannah bug #106.
807 * expand.c (expanding_var): Keep track of which variable we're
808 expanding. If no variable is being expanded, it's the same as
810 * make.h (expanding_var): Declare it.
811 * expand.c (recursively_expand_for_file): Set expanding_var to the
812 current variable we're expanding, unless there's no file info in
813 it (could happen if it comes from the command line or a default
814 variable). Restore it before we exit.

829 * implicit.c (pattern_search): If we allocated a variable set for
830 an impossible file, free it.
831 * variable.c (free_variable_set): New function.

835 strcache, so there's never any need to alloc/free them.
838 * main.c (main): Add "archives" to the .FEATURES variable if
839 archive support is enabled.
840 * doc/make.texi (Special Variables): Document it.

844 * implicit.c (pattern_search): Add checking for DOS pathnames to
845 the pattern rule target LASTSLASH manipulation.

850 * (ALL FILES): Updated copyright and license notices.
852 2006-02-10 Paul D. Smith <psmith@gnu.org>
854 A new internal capability: the string cache is a read-only cache
855 of strings, with a hash table interface for fast lookup. Nothing
856 in the cache will ever be freed, so there's no need for reference
857 counting, etc. This is the beginning of a full solution for
858 Savannah bug #15182, but for now we only store makefile names here.
860 * strcache.c: New file. Implement a read-only string cache.
861 * make.h: Add prototypes for new functions.
862 * main.c (initialize_global_hash_tables): Initialize the string cache.

870 directory time stamp didn't change, except on FAT filesystems.
871 Suggested by J. David Bryan <jdbryan@acm.org>.

876 (func_and): Implement a short-circuiting AND function.
877 (function_table_init): Update the table with the new functions.
878 * doc/make.texi (Conditional Functions): Changed the "if" section
879 to one on general conditional functions. Added documentation for
880 $(and ...) and $(or ...) functions.

890 2006-02-06 Paul D. Smith <psmith@gnu.org>
892 * vpath.c (selective_vpath_search): If the file we find has a
893 timestamp from -o or -W, use that instead of the real time.
894 * remake.c (f_mtime): If the mtime is a special token from -o or
895 -W, don't overwrite it with the real mtime.

913 Fixes Savannah bug #15533.
914 * filedef.h (struct file): Add a new LAST pointer.
916 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do

942 2006-01-21 Eli Zaretskii <eliz@gnu.org>
944 * remake.c (update_goal_chain): Set g->changed instead of
945 incrementing it, as it is only 8-bit wide, and could overflow if
946 many commands got started in update_file.

1007 handling of backslash-newline sequences. Mention the differences
1008 on MS-DOS and MS-Windows.
1010 * NEWS: More details about building the MinGW port and a pointer
1011 to README.W32. Fix the section name that describes the new
1012 backward-incompatible processing of backslash-newline sequences.
1013 The special processing of SHELL set to "cmd" is only relevant to
1014 MS-Windows, not MS-DOS.
1016 2005-12-17 Eli Zaretskii <eliz@gnu.org>

1036 with v_default instead of leaving it "initialized" by whatever
1037 garbage happened to be on the heap.

1046 * implicit.c (pattern_search): If 2nd expansion is not set for
1047 this implicit rule, replace the pattern with the stem directly,
1048 and don't re-expand the variable list. Along with the other

1083 2005-10-24 Paul D. Smith <psmith@gnu.org>
1085 Make secondary expansion optional: its enabled by declaring the
1086 special target .SECONDEXPANSION.
1088 * NEWS: Update information on second expansion capabilities.
1089 * doc/make.texi (Secondary Expansion): Document the
1090 .SECONDEXPANSION special target and its behavior.
1091 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1092 prerequisite list was found in a static pattern rule.
1093 (free_dep_chain): Declare a prototype.
1094 * file.c (parse_prereqs): New function: break out some complexity
1096 (expand_deps): If we aren't doing second expansion, replace % with
1097 the stem for static pattern rules. Call the new function.
1098 * filedef.h (parse_prereqs): Declare a prototype.
1099 * implicit.c (pattern_search): Initialize the new staticpattern
1101 * main.c (second_expansion): Declare a global variable to remember
1102 if the special target has been seen. Initialize the new
1103 staticpattern field for prerequisites.
1104 * make.h: Extern for second_expansion.
1105 * misc.c (free_dep_chain): New function: frees a struct dep list.
1106 * read.c (read_all_makefiles): Initialize the staticpattern field.
1107 (eval_makefile): Ditto.
1108 (record_files): Check for the .SECONDEXPANSION target and set
1109 second_expansion global if it's found.
1110 Use the new free_dep_chain() instead of doing it by hand.
1111 Set the staticpattern field for prereqs of static pattern targets.
1113 2005-10-16 Paul D. Smith <psmith@gnu.org>
1115 * main.c (main): Set CURDIR to be a file variable instead of a
1116 default, so that values of CURDIR inherited from the environment
1117 won't override the make value.
1119 2005-09-26 Paul D. Smith <psmith@gnu.org>
1121 * job.c (construct_command_argv_internal): If the line is empty
1122 remember to free the temporary argv strings.
1125 2005-09-16 Paul D. Smith <psmith@gnu.org>
1127 * job.c (start_job_command): The noerror flag is a boolean (single
1128 bit); set it appropriately.
1129 Reported by Mark Eichin <eichin@metacarta.com>
1131 2005-08-29 Paul D. Smith <psmith@gnu.org>
1133 * function.c (func_error): On Windows, output from $(info ...)
1134 seems to come in the wrong order. Try to force it with fflush().
1136 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1138 * read.c (record_files): Move code that sets stem for static
1139 pattern rules out of the if (!two_colon) condition so it is
1140 also executed for two-colon rules. Fixes Savannah bug #13881.
1142 2005-08-08 Paul D. Smith <psmith@gnu.org>
1144 * make.h: Don't test that __STDC__ is non-0. Some compilers
1145 (Windows for example) set it to 0 to denote "ISO C + extensions".
1148 2005-08-07 Paul D. Smith <psmith@gnu.org>
1150 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1151 conditional (slightly different version of a fix from Eli).
1153 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1154 If make is running in parallel without -k and two jobs die in a
1155 row, but not too close to each other, then make will quit without
1156 waiting for the rest of the jobs to die.
1158 * main.c (die): Don't reset err before calling reap_children() the
1159 second time: we still want it to be in the error condition.
1160 * job.c (reap_children): Use a static variable, rather than err,
1161 to control whether or not the error message should be printed.
1163 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1165 * w32/subproc/sub_proc.c: Include signal.h.
1166 (process_pipe_io, process_file_io): Pass a pointer to a local
1167 DWORD variable to GetExitCodeProcess. If the exit code is
1168 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1170 * job.c [WINDOWS32]: Include windows.h.
1171 (main_thread) [WINDOWS32]: New global variable.
1172 (reap_children) [WINDOWS32]: Get the handle for the main thread
1173 and store it in main_thread.
1175 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1176 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1177 doing anything else. When we are done, close the main thread
1178 handle and exit with status 130.
1180 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1182 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1185 * main.c (find_and_set_default_shell): If found a DOSish shell,
1186 set sh_found and the value of default_shell, and report the
1187 findings in debug mode.
1189 * job.c (construct_command_argv_internal): Check unixy_shell, not
1190 no_default_sh_exe, to decide whether to use Unixy or DOSish
1193 * README.W32: Update with info about the MinGW build.
1195 * build_w32.bat: Support MinGW.
1197 * w32/subproc/build.bat: Likewise.
1199 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1200 printing DWORD args.
1202 * function.c (windows32_openpipe): Fix format strings for printing
1205 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1207 (start_job_command): Fix format string for printing the result of
1209 (start_job_command) [WINDOWS32]: Do not define.
1210 (exec_command): Fix format string for printing HANDLE args.
1212 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1213 to avoid compiler warnings.
1214 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1215 (Note: some of these fixes were submitted independently by J. Grant)
1217 2005-07-30 J. Grant <jg@jguk.org>
1219 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1220 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1221 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1223 2005-07-15 Paul Smith <psmith@gnu.org>
1225 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1226 we don't have a POSIX shell, then revert to the old
1227 backslash-newline behavior (where they are stripped).
1230 2005-07-08 Paul D. Smith <psmith@gnu.org>
1232 * config.h.W32.template: Reorder to match the standard config.h,
1233 for easier comparisons.
1234 From J. Grant <jg@jguk.org>
1236 * maintMakefile: Remove .dep_segment before overwriting it, in
1237 case it's not writable or noclobber is set.
1238 * expand.c (variable_expand_string): Cast result of pointer
1239 arithmetic to avoid a warning.
1240 * main.c (switches): Add full-fledged final initializer.
1242 2005-07-06 Paul D. Smith <psmith@gnu.org>
1244 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1245 * signame.c (strsignal): If we found _sys_siglist[] or
1246 __sys_siglist[] use those instead of sys_siglist[].
1247 From Albert Chin <china@thewrittenword.com>
1249 2005-07-04 Paul D. Smith <psmith@gnu.org>
1251 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1252 globfree(); set up to use the GNU versions.
1253 From Martin Zinser <zinser@zinser.no-ip.info>
1255 2005-07-03 Paul D. Smith <psmith@gnu.org>
1257 From J. Grant <jg@jguk.org>:
1259 * README.W32.template: Update the Windows and tested MSVC versions.
1260 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1261 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1262 * build_w32.bat: Ditto.
1263 * w32/subproc/build.bat: Ditto.
1265 2005-06-28 Paul D. Smith <psmith@gnu.org>
1267 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1268 declaration was checked but not present.
1270 2005-06-27 Paul D. Smith <psmith@gnu.org>
1272 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1273 to unsigned long. Fixes Savannah bug #13550.
1275 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1276 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1277 Fixes Savannah bug #13551.
1279 2005-06-26 Paul D. Smith <psmith@gnu.org>
1281 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1282 it if ANSI_STRING is not set.
1284 2005-06-25 Paul D. Smith <psmith@gnu.org>
1286 * read.c (eval): If no filenames are passed to any of the
1287 "include" variants, don't print an error.
1288 * doc/make.texi (Include): Document this.
1289 Fixes Savannah bug #1761.
1291 * job.c (construct_command_argv_internal): Sanitize handling of
1292 backslash/newline pairs according to POSIX: that is, keep the
1293 backslash-newline in the command script, but remove a following
1294 TAB character, if present. In the fast path, make sure that the
1295 behavior matches what the shell would do both inside and outside
1296 of quotes. In the slow path, quote the backslash and put a
1297 literal newline in the string.
1298 Fixes Savannah bug #1332.
1299 * doc/make.texi (Execution): Document the new behavior and give
1301 * NEWS: Make a note of the new behavior.
1303 * make.h [WINDOWS32]: #include <direct.h>.
1304 Fixes Savannah bug #13478.
1306 * remake.c (name_mtime): If the stat() of a file fails and the -L
1307 option was given and the file is a symlink, take the best mtime of
1308 the symlink we can get as the mtime of the file and don't fail.
1309 Fixes Savannah bug #13280.
1311 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1312 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1313 inside a variable reference. Make this function static as it's
1315 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1316 parsing an unexpanded line looking for semicolons.
1317 Fixes Savannah bug #1454.
1318 * misc.c (remove_comments): Move this to read.c and make it static
1319 as it's only used there. Call find_char_unquote() with new arg.
1320 * make.h: Remove prototypes for find_char_unquote() and
1321 remove_comments() since they're static now.
1323 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1324 its export flag and obtain its value. When we need to re-exec,
1325 increment the value and add it into the environment.
1326 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1327 * NEWS: Mention MAKE_RESTARTS.
1328 * main.c (always_make_set): New variable. Change the -B option to
1329 set this one instead.
1330 (main): When checking makefiles, only set always_make_flag if
1331 always_make_set is set AND the restarts flag is 0. When building
1332 normal targets, set it IFF always_make_set is set.
1333 (main): Avoid infinite recursion with -W, too: only set what-if
1334 files to NEW before we check makefiles if we've never restarted
1335 before. If we have restarted, set what-if files to NEW _after_ we
1337 Fixes Savannah bug #7566:
1339 2005-06-17 Paul D. Smith <psmith@gnu.org>
1341 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1342 in the prerequisites list.
1344 2005-06-12 Paul D. Smith <psmith@gnu.org>
1346 Fix Savannah bug # 1328.
1348 * configure.in: Check for atexit().
1349 * misc.c (close_stdout): Test stdout to see if writes to it have
1350 failed. If so, be sure to exit with a non-0 error code. Based on
1351 code found in gnulib.
1352 * make.h: Prototype.
1353 * main.c (main): Install close_stdout() with atexit().
1355 2005-06-10 Paul D. Smith <psmith@gnu.org>
1357 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1359 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1360 headers; make vmsWaitForChildren() static; extern vmsify().
1361 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1362 Don't create child_execute_job() here (it's in vmsjobs.c).
1363 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1365 2005-06-09 Paul D. Smith <psmith@gnu.org>
1367 * variable.c (push_new_variable_scope): File variables point
1368 directly to the global_setlist variable. So, inserting a new
1369 scope in front of that has no effect on those variables: they
1370 don't go through current_variable_set_list. If we're pushing a
1371 scope and the current scope is global, push it "the other way" so
1372 that the new setlist is in the global_setlist variable, and
1373 next points to a new setlist with the global variable set.
1374 (pop_variable_scope): Properly undo a push with the new
1376 Fixes Savannah bug #11913.
1378 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1380 * job.c (reap_children): Don't die of the command failed but
1381 the dontcare flag is set. Fixes Savannah bug #13216.
1383 * implicit.c (pattern_search): When creating a target from
1384 an implicit rule match, lookup pattern target and set precious
1385 flag in a newly created target. Fixes Savannah bug #13218.
1387 2005-05-13 Paul D. Smith <psmith@gnu.org>
1389 Implement "if... else if... endif" syntax.
1391 * read.c (eval): Push all checks for conditional words ("ifeq",
1392 "else", etc.) down into the conditional_line() function.
1393 (conditional_line): Rework to allow "else if..." clause. New
1394 return value -2 for lines which are not conditionals. The
1395 ignoring flag can now also be 2, which means "already parsed a
1396 true branch". If that value is seen no other branch of this
1397 conditional can be considered true. In the else parsing if there
1398 is extra text after the else, invoke conditional_line()
1399 recursively to see if it's another conditional. If not, it's an
1400 error. If so, raise the conditional value to this level instead
1401 of creating a new conditional nesting level. Special check for
1402 "else" and "endif", which aren't allowed on the "else" line.
1403 * doc/make.texi (Conditional Syntax): Document the new syntax.
1405 2005-05-09 Paul D. Smith <psmith@gnu.org>
1407 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1408 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1409 recurses to the w32 directory, even on non-Windows systems. Use
1410 the method suggested in the automake manual.
1411 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1412 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1414 2005-05-07 Paul D. Smith <psmith@gnu.org>
1416 * main.c (die): If we're dying with a fatal error (not that a
1417 command has failed), write back any leftover tokens before we go.
1419 * job.c (set_child_handler_action_flags): If there are jobs
1420 waiting for the load to go down, set an alarm to go off in 1
1421 second. This allows us to wake up from a potentially long-lasting
1422 read() and start a new job if the load has gone down. Turn it off
1424 (job_noop): Dummy signal handler function.
1425 (new_job): Invoke it with the new semantics.
1427 * docs/make.texi: Document secondary expansion. Various cleanups
1430 2005-05-03 Paul D. Smith <psmith@gnu.org>
1432 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1433 the targets which are to ultimately be made are called "goals";
1434 see the GNU make manual. Also, MAKECMDGOALS, etc.
1436 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1437 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1438 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1440 2005-05-02 Paul D. Smith <psmith@gnu.org>
1442 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1443 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1444 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1445 functions to vmsjobs.c. #include it into jobs.c.
1447 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1448 jobserver tokens. I found that this happens when an exported
1449 recursive variable contains a $(shell ...) function reference: in
1450 this situation we could "forget" to write back a token.
1452 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1453 we have. It's not reliable to depend on the number of children in
1454 our linked list so keep a separate count.
1455 (new_job): Check jobserver_tokens rather than children &&
1456 waiting_jobs. Increment jobserver_tokens when we get one.
1457 (free_child): If jobserver_tokens is 0, internal error. If it's
1458 >1, write a token back to the jobserver pipe (we don't write a
1459 token for the "free" job). Decrement jobserver_tokens.
1461 * main.c: Add variable master_job_slots.
1462 (main): Set it to hold the number of jobs requested if we're the
1463 master process, when using the jobserver.
1464 (die): Sanity checks: first test jobserver_tokens to make sure
1465 this process isn't holding any tokens we didn't write back.
1466 Second, if master_job_slots is set count the tokens left in the
1467 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1469 2005-04-24 Paul D. Smith <psmith@gnu.org>
1471 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1472 with -l# can lose jobserver tokens, because waiting jobs are not
1473 consulted properly when checking for the "free" token.
1475 * job.c (free_child): Count waiting_jobs as having tokens.
1476 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1477 handle jobs waiting for the load to drop.
1479 2005-04-23 Paul D. Smith <psmith@gnu.org>
1481 * main.c (main): Be careful to not core if a variable setting in
1482 the environment doesn't contain an '='. This is illegal but can
1483 happen in broken setups.
1484 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1486 2005-04-12 Paul D. Smith <psmith@gnu.org>
1488 The second expansion feature causes significant slowdown. Timing
1489 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1490 read the makefile before the feature, to 11+s to do the same
1491 operations after the feature. Additionally, memory usage
1492 increased drastically. To fix this I added some intelligence that
1493 avoids the overhead of the second expansion unless it's required.
1495 * dep.h: Add a new boolean field, need_2nd_expansion.
1497 * read.c (eval): When creating the struct dep for the target,
1498 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1499 (record_files): If there's a "%" in a static pattern rule, it gets
1500 converted to "$*" so set need_2nd_expansion to 1.
1502 * file.c (expand_deps): Rework to be more efficient. Only perform
1503 initialize_file_variables(), set_file_variables(), and
1504 variable_expand_for_file() if the need_2nd_expansion is set.
1506 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1507 (pattern_search): Ditto.
1508 * main.c (handle_non_switch_argument): Ditto.
1510 * read.c (read_all_makefiles): Ditto.
1511 (eval_makefile): Ditto.
1513 2005-04-07 Paul D. Smith <psmith@gnu.org>
1515 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1516 * variable.c (sync_Path_environment): Ditto.
1517 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1519 * main.c (main): Define the .FEATURES variable.
1520 * NEWS: Announce .FEATURES.
1521 * doc/make.texi (Special Variables): Document .FEATURES.
1523 * remake.c (check_dep): If a file is .PHONY, update it even if
1524 it's marked intermediate. Fixes Savannah bug #12331.
1526 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1528 * file.c (expand_deps): Factor out the second expansion and
1529 prerequisite line parsing logic from snap_deps().
1531 * file.c (snap_deps): Use expand_deps(). Expand and parse
1532 prerequisites of the .SUFFIXES special target first. Fixes
1533 Savannah bug #12320.
1535 2005-03-13 Paul D. Smith <psmith@gnu.org>
1537 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1540 2005-03-11 Paul D. Smith <psmith@gnu.org>
1542 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1543 available, not undefined (from Earnie Boyd).
1545 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1547 * implicit.c (pattern_search): Mark an intermediate target as
1548 precious if it happened to be a prerequisite of some (other)
1549 target. Fixes Savannah bug #12267.
1551 2005-03-09 Paul D. Smith <psmith@gnu.org>
1553 * read.c (eval_makefile): Add alloca(0).
1554 (eval_buffer): Ditto.
1556 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1558 * main.c (main): Use o_file instead of o_default when defining
1559 the .DEFAULT_TARGET special variable.
1560 * read.c (eval): Use define_variable_global() instead of
1561 define_variable() when setting new value for the .DEFAULT_TARGET
1562 special variable. Fixes Savannah bug #12266.
1564 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1566 * imlicit.c (pattern_search): Mark files for which an implicit
1567 rule has been found as targets. Fixes Savannah bug #12202.
1569 2005-03-04 Paul D. Smith <psmith@gnu.org>
1572 * doc/make.texi (Automatic Variables): Document $|.
1574 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1576 * read.c (record_files): Instead of substituting % with
1577 actual stem value in dependency list replace it with $*.
1578 This fixes stem triple expansion bug.
1580 * implicit.c (pattern_search): Copy stem to a separate
1581 buffer and make it a properly terminated string. Assign
1582 this buffer instead of STEM (which is not terminated) to
1583 f->stem. Instead of substituting % with actual stem value
1584 in dependency list replace it with $*. This fixes stem
1585 triple expansion bug.
1587 2005-03-01 Paul D. Smith <psmith@gnu.org>
1589 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1590 on Windows, as it takes a handle not a pid. Just exit.
1591 Fix from patch #3679, provided by Alessandro Vesely.
1593 * configure.in: Update check for sys_siglist[] from autoconf manual.
1594 * signame.c (strsignal): Update to use the new autoconf macro.
1596 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1598 * read.c (record_files): Add a check for the list of prerequisites
1599 of a static pattern rule being empty. Fixes Savannah bug #12180.
1601 2005-02-28 Paul D. Smith <psmith@gnu.org>
1603 * doc/make.texi (Text Functions): Update docs to allow the end
1604 ordinal for $(wordlist ...) to be 0.
1605 * function.c (func_wordlist): Fail if the start ordinal for
1606 $(wordlist ...) is <1. Matches documentation.
1607 Resolves Savannah support request #103195.
1609 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1610 previously we were stopping when !-q, exactly the opposite. This
1611 has been wrong since version 1.34, in 1994!
1612 (update_file): If we got an error don't break out to run more
1613 double-colon rules: just return immediately.
1614 Fixes Savannah bug #7144.
1616 2005-02-27 Paul D. Smith <psmith@gnu.org>
1618 * misc.c (end_of_token): Make argument const.
1619 * make.h: Update prototype.
1621 * function.c (abspath, func_realpath, func_abspath): Use
1622 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1623 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1624 * read.c (record_files): Ditto.
1625 * variable.c (do_variable_definition): Ditto.
1627 * function.c (func_error): Create a new function $(info ...) that
1628 simply prints the message to stdout with no extras.
1629 (function_table_init): Add new function to the table.
1630 * NEWS: Add $(info ...) reference.
1631 * doc/make.texi (Make Control Functions): Document it.
1633 New feature: if the system supports symbolic links, and the user
1634 provides the -L/--check-symlink-time flag, then use the latest
1635 mtime between the symlink(s) and the target file.
1637 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1638 readlink(). If both are available, define MAKE_SYMLINKS.
1639 * main.c: New variable: check_symlink_flag.
1640 (usage): Add a line for -L/--check-symlink-times to the help string.
1641 (switches): Add -L/--check-symlink-times command line argument.
1642 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1643 print a warning and disable it again.
1644 * make.h: Declare check_symlink_flag.
1645 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1646 if the file is a symlink then check each link in the chain and
1647 choose the NEWEST mtime we find as the mtime for the file. The
1648 newest mtime might be the file itself!
1649 * NEWS: Add information about this new feature.
1650 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1652 Avoid core dumps described in Savannah bug # 12124:
1654 * file.c: New variable snapped_deps remember whether we've run
1656 (snap_deps): Set it.
1657 * filedef.h: Extern it.
1658 * read.c (record_files): Check snapped_deps; if it's set then
1659 we're trying to eval a new target/prerequisite relationship from
1660 within a command script, which we don't support. Fatal.
1662 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1664 Implementation of the .DEFAULT_TARGET special variable.
1666 * read.c (eval): If necessary, update default_target_name when
1668 * read.c (record_files): Update default_target_file if
1669 default_target_name has changed.
1670 * main.c (default_target_name): Define.
1671 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1672 default_target_name is set use default_target_file as a root
1674 * filedef.h (default_target_name): Declare.
1675 * dep.h (free_dep_chain):
1676 * misc.c (free_dep_chain): Change to operate on struct nameseq
1677 and change name to free_ns_chain.
1678 * file.c (snap_deps): Update to use free_ns_chain.
1680 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1682 Implementation of the second expansion in explicit rules,
1683 static pattern rules and implicit rules.
1685 * read.c (eval): Refrain from chopping up rule's dependencies.
1686 Store them in a struct dep as a single dependency line. Remove
1687 the code that implements SySV-style automatic variables.
1689 * read.c (record_files): Adjust the code that handles static
1690 pattern rules to expand all percents instead of only the first
1691 one. Reverse the order in which dependencies are stored so that
1692 when the second expansion reverses them again they appear in
1693 the makefile order (with some exceptions, see comments in
1694 the code). Remove the code that implements SySV-style automatic
1697 * file.c (snap_deps): Implement the second expansion and chopping
1698 of dependency lines for explicit rules.
1700 * implicit.c (struct idep): Define an auxiliary data type to hold
1701 implicit rule's dependencies after stem substitution and
1704 * implicit.c (free_idep_chain): Implement.
1706 * implicit.c (get_next_word): Implement helper function for
1707 parsing implicit rule's dependency lines into words taking
1708 into account variable expansion requests. Used in the stem
1711 * implicit.c (pattern_search): Implement the second expansion
1712 for implicit rules. Also fixes bug #12091.
1714 * commands.h (set_file_variables): Declare.
1715 * commands.c (set_file_variables): Remove static specifier.
1717 * dep.h (free_dep_chain): Declare.
1718 * misc.c (free_dep_chain): Implement.
1720 * variable.h (variable_expand_for_file): Declare.
1721 * expand.c (variable_expand_for_file): Remove static specifier.
1723 * make.h (strip_whitespace): Declare.
1724 * function.c (strip_whitespace): Remove static specifier.
1726 2005-02-26 Paul D. Smith <psmith@gnu.org>
1728 * main.c (main): Check for ferror() when reading makefiles from stdin.
1729 Apparently some shells in Windows don't close pipes properly and
1732 2005-02-24 Jonathan Grant <jg@jguk.org>
1734 * configure.in: Add MinGW configuration options, and extra w32 code
1736 * Makefile.am: Add MinGW configuration options, and extra w32 code
1738 * main.c: Determine correct program string (after last \ without .exe).
1739 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1741 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1742 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1743 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1744 environment support.
1746 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1748 * function.c (func_shell): When initializing error_prefix, check
1749 that reading file name is not null. This fixes long-standing
1750 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1752 2005-02-09 Paul D. Smith <psmith@gnu.org>
1754 * maintMakefile: Update the CVS download URL to simplify them.
1755 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1756 downloading the .texi files from Savannah now.
1758 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1760 * main.c (handle_non_switch_argument): Only add variables to
1761 command_variables if they're not already there: duplicate settings
1762 waste space and can be confusing to read.
1764 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1765 this header is never included by non-WINDOWS32 code, and it
1766 requires <config.h> to define which isn't always included first.
1768 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1769 testing MINGW32 versions.
1771 * main.c (log_working_directory): flush stdout to be sure the WD
1772 change is printed before any stderr messages show up.
1774 2005-02-01 Paul D. Smith <psmith@gnu.org>
1776 * maintMakefile (po_repo): Update the GNU translation site URL.
1778 2004-12-01 Paul D. Smith <psmith@gnu.org>
1780 * main.c (main): Change char* env_shell to struct variable shell_var.
1781 * variable.c (target_environment): Use new shell_var.
1783 2004-11-30 Paul D. Smith <psmith@gnu.org>
1785 * configure.in: The old way we avoided creating build.sh from
1786 build.sh.in before build.sh.in exists doesn't work anymore; we
1787 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1788 the help!). This also keeps automake from complaining.
1789 * Makefile.am (README): Add a dummy target so automake won't
1790 complain that this file doesn't exist when we checkout from CVS.
1791 * maintMakefile (.dep_segment): Rewrite this rule since newer
1792 versions of automake don't provide DEP_FILES.
1794 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1796 Implementation of `realpath' and `abspath' built-in functions.
1798 * configure.in: Check for realpath.
1799 * function.c (abspath): Return an absolute file name that does
1800 not contain any `.' or `..' components, nor repeated `/'.
1801 * function.c (func_abspath): For each name call abspath.
1802 * function.c (func_realpath): For each name call realpath
1803 from libc or delegate to abspath if realpath is not available.
1804 * doc/make.texi (Functions for File Names): Document new functions.
1805 * doc/make.texi (Quick Reference): Ditto.
1807 2004-11-28 Paul D. Smith <psmith@gnu.org>
1809 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1810 arguments. Fixes bug #10252.
1812 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1814 * main.c (main): Set SHELL to v_noexport by default. Remember the
1815 original environment setting of SHELL in the env_shell variable.
1816 * main.h: Export new env_shell variable.
1817 * variable.c (target_environment): If we find a v_noexport
1818 variable for SHELL, add a SHELL variable with the env_shell value.
1819 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1820 * doc/make.texi (Variables/Recursion): Ditto.
1822 2004-11-28 Paul D. Smith <psmith@gnu.org>
1824 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1825 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1826 Patch by Alessandro Vesely.
1828 2004-11-12 Paul D. Smith <psmith@gnu.org>
1830 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1831 the command line if it's inside a string.
1832 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1834 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1836 * function.c (func_lastword): New function: return last word
1837 from the list of words.
1838 * doc/make.texi: Document $(lastword ). Fix broken links in
1839 Quick Reference section.
1841 2004-10-06 Paul D. Smith <psmith@gnu.org>
1843 Apply patch from Alessandro Vesely, provided with bug # 9748.
1844 Fix use of tmpnam() to work with Borland C.
1846 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1847 construction of a temporary filename, and call new function
1848 create_batch_filename().
1849 (create_batch_filename) [WINDOWS32]: New function to create a
1852 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1854 * read.c (record_target_var): Expand simple pattern-specific
1856 * variable.c (initialize_file_variables): Do not expand simple
1857 pattern-specific variable.
1859 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1861 * remake.c (update_file_1): When rebuilding makefiles inherit
1862 dontcare flag from a target that triggered update.
1864 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1866 * variable.c (initialize_file_variables): Mark pattern-specific
1867 variable as a per-target and copy export status.
1869 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1871 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1873 * implicit.c (pattern_search): When considering an implicit rule's
1874 prerequisite check that it is actually a target rather then
1875 just an entry in the file hashtable.
1877 2004-09-21 Paul D. Smith <psmith@gnu.org>
1879 * read.c (readstring): Fix some logic errors in backslash handling.
1880 (eval): Remove some unnecessary processing in buffer handling.
1881 (record_target_var): Assert that parse_variable_definition() succeeded.
1882 Reported by: Markus Mauhart <qwe123@chello.at>.
1884 * misc.c: Removed the sindex() function. All instances of this
1885 function were trivially replaceable by the standard strstr()
1886 function, and that function will always have better (or certainly
1887 no worse) performance than the very simple-minded algorithm
1888 sindex() used. This can matter with complex makefiles.
1889 * make.h: Remove the prototype for sindex().
1890 * function.c (subst_expand): Convert sindex() call to strstr().
1891 This means we no longer need to track the TLEN value so remove that.
1892 (func_findstring): Convert sindex() to strstr().
1893 * commands.c (chop_commands): Convert sindex() calls to strstr().
1894 Suggested by: Markus Mauhart <qwe123@chello.at>.
1896 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1897 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1898 If SHELL is set to CMD.EXE then assume it's batch-mode and
1899 non-unixy. I wrote the code differently from the patch, though,
1900 to make it safer. This also resolves bug #9174.
1902 2004-09-20 Paul D. Smith <psmith@gnu.org>
1904 * expand.c (variable_expand_string): Modify to invoke
1905 patsubst_expand() instead of subst_expand(); the latter didn't
1906 handle suffix patterns correctly.
1907 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1908 was used only from variable_expand_string() and is no longer used
1910 (func_subst): Ditto, on call to subst_expand().
1911 (patsubst_expand): Require the percent pointers to point to the
1912 character after the %, not to the % itself.
1913 * read.c (record_files): New call criteria for patsubst_expand().
1914 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1915 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1917 2004-09-19 Paul D. Smith <psmith@gnu.org>
1919 * function.c (subst_expand): Fix a check in by_word: look for a
1920 previous blank if we're beyond the beginning of the string, not
1921 the beginning of the word.
1922 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1924 2004-05-16 Paul D. Smith <psmith@gnu.org>
1926 * remake.c (update_goal_chain): Change the argument specifying
1927 whether we're rebuilding makefiles to be a global variable,
1928 REBUILDING_MAKEFILES.
1929 (complain): Extract the code that complains about no rules to make
1930 a target into a separate function.
1931 (update_file_1): If we tried to rebuild a file during the makefile
1932 rebuild phase and it was dontcare, then no message was printed.
1933 If we then try to build the same file during the normal build,
1934 print a message this time.
1935 (remake_file): Don't complain about un-remake-able files when
1936 we're rebuilding makefiles.
1938 2004-05-11 Paul D. Smith <psmith@gnu.org>
1940 * job.c (construct_command_argv_internal): OS/2 patches from
1941 Andreas Buening <andreas.buening@nexgo.de>.
1943 2004-05-10 Paul D. Smith <psmith@gnu.org>
1945 * remake.c (update_file): Don't walk the double-colon chain unless
1946 this is a double-colon rule. Fix suggested by Boris Kolpackov
1947 <boris@kolpackov.net>.
1949 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1950 * readme.vms: New section describing OpenVMS support and issues.
1951 * default.c (default_variables): Add support for IA64.
1952 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1953 without some privilege aborts make with the error
1954 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1955 pressing Ctrl+Y and the input device is no terminal. The change
1956 catches this error and just continues.
1958 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1960 2004-04-25 Paul D. Smith <psmith@gnu.org>
1962 * commands.c (set_file_variables): Set $< properly in the face of
1963 order-only prerequisites.
1964 Patch from Boris Kolpackov <boris@kolpackov.net>
1966 2004-04-21 Bob Byrnes <byrnes@curl.com>
1968 * main.c (main): Notice failures to remake makefiles.
1970 2004-03-28 Paul D. Smith <psmith@gnu.org>
1972 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1974 * job.c: No default shell for RISC OS.
1975 (load_too_high): Hard-code the return to 1.
1976 (construct_command_argv_internal): No sh_chars or sh_cmds.
1977 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1979 2004-03-20 Paul D. Smith <psmith@gnu.org>
1981 * variable.c (do_variable_definition): Don't append from the
1982 global set if a previous non-appending target-specific variable
1983 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
1986 * expand.c (reference_variable): Don't give up on variables with
1987 no value that have the target-specific append flag set: they might
1988 have a value after all. Reported by Oliver Schmidt
1989 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
1990 <nikulin@dx1cmd.inp.nsk.su>.
1992 * rule.c (count_implicit_rule_limits): Don't delete patterns which
1993 refer to absolute pathnames in directories that don't exist: some
1994 portion of the makefile could create those directories before we
1995 match the pattern. Fixes bugs #775 and #108.
1997 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
1999 * main.c (main): Free makefile_mtimes if we have any.
2000 * README.W32.template: Update documentation for the current status
2001 of the MS-Windows port.
2002 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2003 environment variable is sometimes already defined which causes the
2005 * main.c (debug_signal_handler): Only define this function if
2006 SIGUSR1 is available.
2008 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2010 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2011 * README.OS2.template: Documentation updates.
2012 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2013 link line for safety.
2014 * maintMakefile (build.sh.in): Remove an extraneous ")".
2015 * job.c (child_execute_job): Close saved FDs.
2016 * job.c (exec_command) [OS/2]: exec_command(): If the command
2017 can't be exec'ed and if the shell is not Unix-sh, then try again
2018 with argv = { "cmd", "/c", ... }. Normally, this code is never
2019 reached for the cmd shell unless the command really doesn't exist.
2020 (construct_command_argv_internal) [OS/2]: The code for cmd
2021 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2022 The CMD builtin commands are case insensitive so use strcasecmp().
2024 2004-03-19 Paul D. Smith <psmith@gnu.org>
2026 * read.c (do_define): Re-order line counter increment so the count
2027 is accurate (we were losing one line per define). Reported by
2028 Dave Yost <Dave@Yost.com>.
2030 2004-03-06 Paul D. Smith <psmith@gnu.org>
2032 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2034 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2035 * misc.c (message,error,fatal): Ditto.
2036 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2037 * config.h.W32.template: Ditto.
2038 * config.h-vms.template: Ditto.
2039 * config.ami.template: Ditto.
2041 2004-03-04 Paul D. Smith <psmith@gnu.org>
2043 * README.template: Add a note about broken /bin/sh on SunOS
2044 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2046 * misc.c (message, error, fatal): Don't use "..." if we're using
2047 varargs. ansi2knr should handle this but it doesn't work: it
2048 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2049 done. On many systems (SunOS for example) va_dcl is a #define.
2050 So, force the use of the non-"..." version on pre-ANSI compilers.
2052 * maintMakefile (sign-dist): Create some rules to help automate
2053 the new GNU ftp upload method.
2055 2004-02-24 Paul D. Smith <psmith@gnu.org>
2057 * config.h.W32.template: Add HAVE_STDARG_H
2058 * config.h-vms.template: Ditto.
2059 * config.ami.template: Ditto.
2061 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2063 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2064 * build_w32.bat: Remove extra "+".
2066 2004-02-23 Paul D. Smith <psmith@gnu.org>
2068 * make.h: Create an UNUSED macro to mark unused parameters.
2069 * (many): Clean up warnings by applying UNUSED, fixing
2070 signed/unsigned incompatibilities, etc.
2072 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2074 * filedef.h: Name the command_state enumeration.
2075 * file.c (set_command_state): Use the enumeration in the function
2078 * configure.in: Explicitly set SET_MAKE to empty, to disable
2079 MAKE=make even when no make already exists. Fix bug #3823.
2081 2004-02-22 Paul D. Smith <psmith@gnu.org>
2083 * maintMakefile: Perl script to clean up all non-CVS files. Use
2084 it on all the subdirectories for the cvs-clean target.
2086 * main.c (decode_switches): Require non-empty strings for all our
2087 string command-line options. Fixes Debian bug # 164165.
2089 * configure.in: Check for stdarg.h and varargs.h.
2090 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2091 for printing messages.
2092 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2097 A number of patches for OS/2 support from Andreas Buening
2098 <andreas.buening@nexgo.de>:
2100 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2101 disable the SIGCHLD handler.
2102 (reap_children) [OS/2]: Remove special handling of job_rfd.
2103 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2104 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2105 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2106 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2107 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2110 2004-02-21 Paul D. Smith <psmith@gnu.org>
2112 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2113 <mail@kristov.de> reports that if process_begin() fails we don't
2114 handle the error condition correctly in all cases.
2115 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2116 to have a newline on the message.
2118 * job.c (construct_command_argv_internal): Add "test" to UNIX
2119 sh_cmds[]. Fixes Savannah bug # 7606.
2121 2004-02-04 Paul D. Smith <psmith@gnu.org>
2123 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2124 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2125 Hartmut Becker <Hartmut.Becker@hp.com>.
2127 2004-01-21 Paul D. Smith <psmith@gnu.org>
2129 * job.c (load_too_high): Implement an algorithm to control the
2130 "thundering herd" problem when using -l to control job creation
2131 via the load average. The system only recomputes the load once a
2132 second but we can start many jobs in a second. To solve this we
2133 keep track of the number of jobs started in the last second and
2134 apply a weight to try to guess what a correct load would be.
2135 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2136 Also fixes bug #4693.
2137 (reap_children): Decrease the job count for this second.
2138 (start_job_command): Increase the job count for this second.
2140 * read.c (conditional_line): Expand the text after ifn?def before
2141 checking to see if it's a single word. Fixes bug #7257.
2143 2004-01-09 Paul D. Smith <psmith@gnu.org>
2145 * file.c (print_file): Recurse to print all targets in
2146 double-colon rules. Fixes bug #4518, reported (with patch) by
2147 Andrew Chatham <chatham@google.com>.
2149 2004-01-07 Paul D. Smith <psmith@gnu.org>
2151 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2152 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2153 AC_FUNC_SETVBUF_REVERSED.
2155 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2156 (MAKE Variable): Fix Savannah bug #4898.
2158 * job.c (construct_command_argv_internal): Add "!" to the list of
2159 shell escape chars. POSIX sh allows it to appear before a
2160 command, to negate the exit code. Fixes bug #6404.
2162 * implicit.c (pattern_search): When matching an implicit rule,
2163 remember which dependencies have the ignore_mtime flag set.
2164 Original fix provided in Savannah patch #2349, by Benoit
2165 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2167 2003-11-22 Paul D. Smith <psmith@gnu.org>
2169 * README.W32.template (Outputs): Clarification on -j with
2170 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2173 2003-11-02 Paul D. Smith <psmith@gnu.org>
2175 * function.c (func_if): Strip all the trailing whitespace from the
2176 condition, then don't expand it. Fixed bug # 5798.
2178 * expand.c (recursively_expand_for_file): If we're expanding a
2179 variable with no file context, then use the variable's context.
2182 2003-10-21 Paul D. Smith <psmith@gnu.org>
2184 * main.c (log_working_directory): Add newlines to printf()s.
2186 * README.cvs: Add a note to ignore warnings during autoreconf.
2188 * maintMakefile (po_repo): Set a new URL for PO file updates.
2189 (get-config/config.guess get-config/config.sub): Get these files
2190 from the Savannah config project instead of ftp.gnu.org.
2192 2003-10-05 Paul Eggert <eggert@twinsun.com>
2194 * main.c (main): Avoid potential subscript error if environ has
2197 2003-08-22 Paul D. Smith <psmith@gnu.org>
2199 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2200 systems which don't yet implement the C89 standard :-/.
2202 2003-07-18 Paul D. Smith <psmith@gnu.org>
2204 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2205 [WINDOWS32]: Initialize hash.
2207 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2209 * dir.c (read_dirstream): Provide a workaround for broken versions of
2210 the MinGW dirent structure.
2212 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2214 * w32/include/dirent.h: Add __MINGW32__ filter.
2216 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2218 * make.h: Add global declaration of *make_host.
2219 * main.c (print_usage): Remove local declaration of *make_host.
2220 (print_version): Display "This program built for ..." after Copyright
2223 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2225 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2226 execution of "makeinfo --html make.texi".
2228 2003-04-30 Paul D. Smith <psmith@gnu.org>
2230 * build.template: Make some changes to maybe allow this script to
2231 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2233 * README.OS2.template: New file for OS/2 support. Original
2234 contributed by Andreas Buening.
2235 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2238 2003-04-19 Paul D. Smith <psmith@gnu.org>
2240 Fix bug #1405: allow a target to match multiple pattern-specific
2243 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2244 variable.c, where they've always belonged.
2245 * rule.h: Move the prototypes and struct pattern_var as well.
2246 * variable.c (initialize_file_variables): Invoke
2247 lookup_pattern_var() in a loop, until no more matches are found.
2248 If a match is found, create a new variable set for the target's
2249 pattern variables. Then merge the contents of each matching
2250 pattern variable set into the target's pattern variable set.
2251 (lookup_pattern_var): Change this function to be usable
2252 in a loop. It takes a starting position: if NULL, start at the
2253 beginning; if non-NULL, start with the pattern variable after that
2254 position, and return the next matching pattern.
2255 (create_pattern_var): Create a unique instance of
2256 pattern-specific variables for every definition in the makefile.
2257 Don't combine the same pattern together. This allows us to
2258 process the variable handling properly even when the same pattern
2259 is used multiple times.
2260 (parse_variable_definition): New function: break out the parsing
2261 of a variable definition line from try_variable_definition.
2262 (try_variable_definition): Call parse_variable_definition to
2264 (print_variable_data_base): Print out pattern-specific variables.
2265 * variable.h (struct variable): Remember when a variable is
2266 conditional. Also remember its flavor.
2267 (struct pattern_var): Instead of keeping a variable set, we just
2268 keep a single variable for each pattern.
2269 * read.c (record_target_var): Each pattern variable contains only a
2270 single variable, not a set, so create it properly.
2271 * doc/make.texi (Pattern-specific): Document the new behavior.
2273 2003-04-17 Paul D. Smith <psmith@gnu.org>
2275 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2276 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2277 file/directory naming rules for VMS so I can't tell whether this
2280 2003-04-09 Paul D. Smith <psmith@gnu.org>
2282 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2283 DOS-style pathnames: backslash separators and drive specifiers.
2285 2003-03-28 Paul D. Smith <psmith@gnu.org>
2287 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2288 the intermediate flag on all targets. Fixes bug #2515.
2290 2003-03-24 Paul D. Smith <psmith@gnu.org>
2292 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2293 Upgrade to autoconf 2.57 and automake 1.7.3.
2295 * job.c: More OS/2 changes from Andreas Buening.
2297 * file.c (print_file): Fix variable initialization.
2300 * remake.c (notice_finished_file):
2302 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2303 some calls (like readdir()) return NULL in valid situations
2304 without resetting errno. Fixes bug #2846.
2306 2003-02-25 Paul D. Smith <psmith@gnu.org>
2308 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2310 * job.c (_is_unixy_shell) [OS/2]: New function.
2311 Set default shell to /bin/sh.
2312 (reap_children): Close the job_rfd pipe here since we don't use a
2314 (set_child_handler_action_flags): define this to empty on OS/2.
2315 (start_job_command): Close the jobserver pipe and use
2316 child_execute_job() instead of fork/exec.
2317 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2318 rather than exec'ing, then reconfigure stdin/stdout.
2319 (exec_command): Rewrite to use spawn instead of exec. Return the
2322 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2323 in DOS. Handle the TEMP environment variable as in DOS. Don't
2324 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2325 use -j in DOS mode. Use child_execute_job() instead of
2328 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2331 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2332 prototypes that return values.
2334 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2336 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2337 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2339 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2342 2003-02-24 Paul D. Smith <psmith@gnu.org>
2344 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2345 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2346 (child_execute_job) [VMS]: Handle error status properly.
2347 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2349 * function.c (func_shell): Use EINTRLOOP() while reading from the
2350 subshell pipe (Fixes bug #2502).
2351 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2353 * main.c (main): Ditto.
2355 2003-01-30 Paul D. Smith <psmith@gnu.org>
2357 * read.c (eval): eval() was not fully reentrant, because the
2358 collapsed buffer was static. Change it to be an automatic
2359 variable so that eval() can be invoked recursively.
2361 (eval): Apply patch # 1022: fix memory reference error on long
2362 target-specific variable lines.
2363 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2365 * function.c (check_numeric): Combine the is_numeric() function
2366 into this function, since it's only called from one place.
2367 Constify this function. Have it print the incorrect string in the
2368 error message. Fixes bug #2407.
2369 (strip_whitespace): Constify.
2370 (func_if): Constify.
2371 * expand.c (expand_argument): Constify.
2373 2003-01-29 Paul D. Smith <psmith@gnu.org>
2375 Fix bug # 2169, also reported by other people on various systems.
2377 * make.h: Some systems, such as Solaris and PTX, do not fully
2378 implement POSIX-compliant SA_RESTART functionality; important
2379 system calls like stat() and readdir() can still fail with EINTR
2380 even if SA_RESTART has been set on the signal handler. So,
2381 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2382 EINTR for system calls which return -1 or 0 (NULL), respectively,
2384 Also, remove the old atomic_stat()/atomic_readdir() and
2385 HAVE_BROKEN_RESTART handling.
2387 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2389 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2390 * remake.c (touch_file): Ditto.
2392 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2393 * read.c (construct_include_path): Ditto.
2394 * remake.c (name_mtime): Ditto.
2395 * vpath.c (selective_vpath_search): Ditto.
2396 * dir.c (find_directory): Ditto.
2397 (local_stat): Ditto.
2398 (find_directory): Use ENULLLOOP() to wrap opendir().
2399 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2401 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2402 atomic_readdir() handling.
2404 2003-01-22 Paul D. Smith <psmith@gnu.org>
2406 * function.c (func_call): Fix Bug #1744. If we're inside a
2407 recursive invocation of $(call ...), mask any of the outer
2408 invocation's arguments that aren't used by this one, so that this
2409 invocation doesn't "inherit" them accidentally.
2411 2002-12-05 Paul D. Smith <psmith@gnu.org>
2413 * function.c (subst_expand): Valery Khamenia reported a
2414 pathological performance hit when doing substitutions on very
2415 large values with lots of words: turns out we were invoking
2416 strlen() a ridiculous number of times. Instead of having each
2417 call to sindex() call strlen() again, keep track of how much of
2418 the text we've seen and pass the length to sindex().
2420 2002-11-19 Paul D. Smith <psmith@gnu.org>
2422 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2425 2002-11-16 Paul D. Smith <psmith@gnu.org>
2427 * NMakefile.template (OBJS): Add hash.c object file.
2428 * SMakefile.template (srcs): Ditto.
2429 * Makefile.ami (objs): Ditto.
2430 * build_w32.bat: Ditto.
2432 * Makefile.DOS.template: Remove extra dependencies.
2434 2002-10-25 Paul D. Smith <psmith@gnu.org>
2436 * expand.c (install_variable_buffer): New function. Install a new
2437 variable_buffer context and return the previous one.
2438 (restore_variable_buffer): New function. Free the current
2439 variable_buffer context and put a previously saved one back.
2440 * variable.h: Prototypes for {install,restore}_variable_buffer.
2441 * function.c (func_eval): Push a new variable_buffer context
2442 before we eval, then restore the old one when we're done.
2445 * read.c (install_conditionals): New function. Install a new
2446 conditional context and return the previous one.
2447 (restore_conditionals): New function. Free the current
2448 conditional context and put a previously saved one back.
2449 (eval): Use the {install,restore}_conditionals for "include"
2451 (eval_buffer): Use {install,restore}_conditionals to preserve the
2452 present conditional state before we evaluate the buffer.
2455 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2457 (Recursion): Add a variable index entry for CURDIR.
2459 * README.cvs: Update to appropriate versions.
2460 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2461 don't need to copy loadavg.c: automake is smart enough to create
2462 it for me. Still have a bug in automake related to ansi2knr tho.
2464 2002-10-14 Paul D. Smith <psmith@gnu.org>
2466 * remake.c (notice_finished_file): Only touch targets if they have
2467 at least one command (as per POSIX). Resolve Bug #1418.
2469 * *.c: Convert to using ANSI C-style function definitions.
2470 * Makefile.am: Enable the ansi2knr feature of automake.
2471 * configure.in: ditto.
2473 2002-10-13 Paul D. Smith <psmith@gnu.org>
2475 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2476 for automatic variable values like $^, etc. In the case of very
2477 large lists of prerequisites this causes problems. Instead reuse
2478 a static buffer (resizeable) for each variable.
2480 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2481 target-specific variable definitions. Check for it and set an
2483 (record_target_var): Set the export field to v_export if the
2484 "exported" flag is set.
2485 * doc/make.texi (Target-specific): Document the ability to use
2488 * doc/make.texi: Change the name of the section on automatic
2489 variables from "Automatic" to "Automatic Variables". Added text
2490 clarifying the scope of automatic variables.
2492 2002-10-04 Paul D. Smith <psmith@gnu.org>
2494 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2496 (record_files): Ditto.
2498 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2499 the search for the '=' to only within the enclosing parens.
2501 2002-10-03 Paul D. Smith <psmith@gnu.org>
2503 Version 3.80 released.
2505 * dir.c: Change hash functions to use K&R function definition style.
2506 * function.c: Ditto.
2508 * variable.c: Ditto.
2510 Update to automake 1.7.
2512 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2513 (pdf): Remove this target as automake now provides one.
2515 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2517 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2519 * makefile.com: Updates for GNU make 3.80.
2520 * makefile.vms: Ditto.
2522 2002-09-23 Paul D. Smith <psmith@gnu.org>
2524 * read.c (enum make_word_type): Remove w_comment.
2525 (get_next_mword): Don't treat comment characters as special; where
2526 this function is used we will never see a comment (it's stripped
2527 before we get here) and treating comments specially means that
2528 targets like "foo\#bar" aren't handled properly.
2530 2002-09-18 Paul D. Smith <psmith@gnu.org>
2532 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2534 * read.c (eval): Expansion of arguments to export/unexport was
2535 ignoring all arguments after the first one. Change the algorithm
2536 to expand the whole line once, then parse the results.
2538 2002-09-17 Paul D. Smith <psmith@gnu.org>
2540 Fix Bug #940 (plus another bug I found while looking at this):
2542 * read.c (record_target_var): enter_file() will add a new entry if
2543 it's a double-colon target: we don't want to do that in this
2544 situation. Invoke lookup_file() and only enter_file() if it does
2545 not already exist. If the file we get back is a double-colon then
2546 add this variable to the "root" double-colon target.
2548 * variable.c (initialize_file_variables): If this file is a
2549 double-colon target but is not the "root" target, then initialize
2550 the root and make the root's variable list the parent of our
2553 2002-09-13 Paul D. Smith <psmith@gnu.org>
2555 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2557 * hash.c (round_up_2): Get rid of a warning.
2559 2002-09-12 Paul D. Smith <psmith@gnu.org>
2561 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2562 so it doesn't complain about getloadavg.c.
2564 * commands.c (set_file_variables): Make sure we always alloca() at
2565 least 1 character for the value of $? (for '\0').
2567 2002-09-11 Paul D. Smith <psmith@gnu.org>
2569 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2570 macro to use RESULT instead of the incorrect _RESULT_.
2572 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2573 and atomic_readdir(). We need to #include dirent.h to get this to
2575 * misc.c (atomic_readdir): Fix typos.
2577 2002-09-10 Paul D. Smith <psmith@gnu.org>
2579 * read.c (eval): Expand variable lists given to export and
2580 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2581 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2583 * doc/make.texi (Variables/Recursion): Document this.
2584 (Conditional Syntax): And here.
2586 2002-09-09 Paul D. Smith <psmith@gnu.org>
2588 * configure.in: Check for memmove().
2590 2002-09-07 Paul D. Smith <psmith@gnu.org>
2592 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2593 Michael Sterrett <msterret@coat.com> reports that while it has
2594 SA_RESTART, it does not work properly.
2596 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2597 that invokes stat() and loops to do it again if it returns EINTR.
2598 (atomic_readdir): Ditto, with readdir().
2600 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2601 and readdir() to atomic_stat() and atomic_readdir().
2603 2002-09-04 Paul D. Smith <psmith@gnu.org>
2605 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2606 reports that GNU make sometimes doesn't recognize that targets can
2607 be made, when directories can be created as prerequisites. He
2608 reports that changing the order of predicates in the DEP->changed
2609 flag test so that lookup_file() is always performed, solves this
2612 2002-08-08 Paul D. Smith <psmith@gnu.org>
2614 * configure.in: Require a newer version of gettext.
2616 * misc.c (perror_with_name): Translate the format string (for
2617 right-to-left language support).
2618 (pfatal_with_name): Ditto.
2620 * main.c: Create a static array of strings to store the usage
2621 text. This is done to facilitate translations.
2622 (struct command_switch): Remove argdesc and description fields.
2623 (switches): Remove values for obsolete fields.
2624 (print_usage): Print each element of the usage array.
2626 * hash.c: Change function definitions to be K&R style.
2628 2002-08-02 Paul D. Smith <psmith@gnu.org>
2630 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2631 this one because it's too hard to get right. We'll look at it for
2633 * main.c (main): Don't create the .TARGETS variable.
2634 * variable.c (handle_special_var): Don't handle .TARGETS.
2636 2002-08-01 Paul D. Smith <psmith@gnu.org>
2638 * main.c (switches): Add a new option, -B (--always-make). If

2640 if they don't appear to be out of date.
2641 (always_make_flag): New flag.
2642 * make.h: Extern always_make_flag.
2643 * remake.c (update_file_1): Check always_make_flag; if it's set we
2644 will always rebuild any target we can, even if none of its
2645 prerequisites are newer.
2648 * doc/make.texi (Shell Function): Make it clear that make
2649 variables marked as "export" are not passed to instances of the
2652 Add new introspection variable .VARIABLES and .TARGETS.
2654 * variable.c (handle_special_var): New function. If the variable
2655 reference passed in is "special" (.VARIABLES or .TARGETS),
2656 calculate the new value if necessary. .VARIABLES is handled here:
2657 walk through the hash of defined variables and construct a value
2658 which is a list of the names. .TARGETS is handled by
2659 build_target_list().
2660 (lookup_variable): Invoke handle_special_var().
2661 * file.c (build_target_list): Walk through the hask of known files
2662 and construct a list of the names of all the ones marked as
2664 * main.c (main): Initialize them to empty (and as simple variables).
2665 * doc/make.texi (Special Variables): Document them.
2666 * NEWS: Mention them.
2668 * variable.h (struct variable): Add a new flag "exportable" which
2669 is true if the variable name is valid for export.
2670 * variable.c (define_variable_in_set): Set "exportable" when a new
2671 variable is defined.
2672 (target_environment): Use the "exportable" flag instead of
2673 re-checking the name here... an efficiency improvement.
2675 2002-07-31 Paul D. Smith <psmith@gnu.org>
2677 * config.h-vms.template: Updates to build on VMS. Thanks to
2678 Brian_Benning@aksteel.com for helping verify the build.
2679 * makefile.com: Build the new hash.c file.
2680 * hash.h: Use strcpmi(), not stricmp(), in the
2681 HAVE_CASE_INSENSITIVE_FS case.
2683 2002-07-30 Paul D. Smith <psmith@gnu.org>
2685 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2686 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2687 Reported by <Brian_Benning@aksteel.com>.
2689 2002-07-10 Paul D. Smith <psmith@gnu.org>
2691 * variable.c (pop_variable_scope): Remove variable made unused by
2692 new hash infrastructure.
2693 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2694 comparisons as well as name comparisons.
2695 * variable.h: Add a prototype for new hash_init_function_table().
2696 * file.c (lookup_file): Remove variables made unused by new hash
2698 * dir.c (directory_contents_hash_2): Missing return of hash value.
2699 (dir_contents_file_exists_p): Remove variables made unused by new
2700 hash infrastructure.
2703 Installed Greg McGary's integration of the hash functions from the
2704 GNU id-utils package:
2706 2002-07-10 Greg McGary <greg@mcgary.org>
2708 * scripts/functions/filter-out: Add literals to to the
2709 pattern space in order to add complexity, and trigger
2710 use of an internal hash table. Fix documentation strings.
2711 * scripts/targets/INTERMEDIATE: Reverse order of files
2712 passed to expected `rm' command.
2714 2002-07-10 Greg McGary <greg@mcgary.org>

2773 (struct a_pattern): New struct.
2774 (func_filter_filterout): Pass through patterns noting boundaries

2786 (find_char_unquote): Accept two char-constant stop chars, rather
2787 than a string constant, avoiding zillions of calls to strchr.
2788 Tighten inner search loops to test only for desired delimiters.

2806 2002-07-10 Paul D. Smith <psmith@gnu.org>
2808 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2809 prerequisite list. A real SysV make will expand the entire
2810 prerequisites list _twice_: we don't do that as it's a big
2811 backward-compatibility problem. We only replace those specific
2814 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2815 references left in the list of prerequisites. Check for .POSIX as
2816 we record targets, so we can disable non-POSIX behavior while
2817 reading makefiles as well as running them.
2818 (eval): Check the prerequisite list to see if we have anything
2819 that looks like a SysV prerequisite variable reference.
2821 2002-07-09 Paul D. Smith <psmith@gnu.org>
2823 * doc/make.texi (Prerequisite Types): Add a new section describing
2824 order-only prerequisites.
2826 * read.c (uniquize_deps): If we have the same file as both a
2827 normal and order-only prereq, get rid of the order-only prereq,
2828 since the normal one supersedes it.
2830 2002-07-08 Paul D. Smith <psmith@gnu.org>
2832 * AUTHORS: Added Greg McGary to the AUTHORS file.
2833 * NEWS: Blurbed order-only prerequisites.
2834 * file.c (print_file): Show order-only deps properly when printing
2837 * maintMakefile: Add "update" targets for wget'ing the latest
2838 versions of various external files. Taken from Makefile.maint in
2841 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2842 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2844 2002-07-07 Paul D. Smith <psmith@gnu.org>
2846 * po/*.po: Remove. We'll use wget to retrieve them at release
2849 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2850 rather than a shell you get an exception. Make sure we look up
2851 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2853 * remake.c (notice_finished_file): Fix handling of -t flag.
2854 Patch provided by Henning Makholm <henning@makholm.net>.
2856 * implicit.c (pattern_search): Some systems apparently run short
2857 of stack space, and using alloca() in this function caused an
2858 overrun. I modified it to use xmalloc() on the two variables
2859 which seemed like they might get large. Fixes Bug #476.
2861 * main.c (print_version): Update copyright notice to conform with
2863 (print_usage): Update help output.
2865 * function.c (func_eval): Create a new make function, $(eval
2866 ...). Expand the arguments, put them into a buffer, then invoke
2867 eval_buffer() on the resulting string.
2868 (func_quote): Create a new function, $(quote VARNAME). Inserts
2869 the value of the variable VARNAME without expanding it any
2872 * read.c (struct ebuffer): Change the linebuffer structure to an
2873 "eval buffer", which can be either a file or a buffer.
2874 (eval_makefile): Move the code in the old read_makefile() which
2875 located a makefile into here: create a struct ebuffer with that
2876 information. Have it invoke the new function eval() with that
2878 (eval_buffer): Create a new function that creates a struct ebuffer
2879 that holds a string buffer instead of a file. Have it invoke
2880 eval() with that ebuffer.
2881 (eval): New function that contains the guts of the old
2882 read_makefile() function: this function parses makefiles. Obtains
2883 data to parse from the provided ebuffer. Some modifications to
2884 make the flow of the function cleaner and clearer. Still could
2885 use some work here...
2886 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2887 contents of the define/endef variable from the ebuffer.
2888 (readstring): Read the next line from a string-style ebuffer.
2889 (readline): Read the next line from an ebuffer. If it's a string
2890 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2893 * dep.h (eval_buffer): Prototype eval_buffer();
2895 * variable.c (do_variable_definition): Make sure that all
2896 non-target-specific variables are registered in the global set.
2897 If we're invoked from an $(eval ...) we might be inside a $(call
2898 ...) or other function which has pushed a variable scope; we still
2899 want to define our variables from evaluated makefile code in the
2902 2002-07-03 Greg McGary <greg@mcgary.org>
2904 * dep.h (struct dep) [ignore_mtime]: New member.
2905 [changed]: convert to a bitfield.
2906 * implicit.c (pattern_search): Zero ignore_mtime.
2907 * main.c (main, handle_non_switch_argument): Likewise.
2908 * rule.c (convert_suffix_rule): Likewise.
2909 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2910 (read_makefile): Parse '|' in prerequisite list.
2911 (uniquize_deps): Consider ignore_mtime when comparing deps.
2912 * remake.c (update_file_1, check_dep): Don't force remake for
2913 dependencies that have d->ignore_mtime.
2914 * commands.c (FILE_LIST_SEPARATOR): New constant.
2915 (set_file_variables): Don't include a
2916 prerequisite in $+, $^ or $? if d->ignore_mtime.
2919 2002-06-18 Paul D. Smith <psmith@gnu.org>
2921 * make.texinfo: Updates for next revision. New date/rev/etc.
2922 Recreate all Info menus. Change license on the manual to the GNU
2923 Free Documentation License. A number of typos.
2924 (Variables Simplify): Don't use "-" before it's defined.
2925 (Automatic Prerequisites): Rewrite the target example to work
2926 properly if the compile fails. Remove incorrect comments about
2927 how "set -e" behaves.
2928 (Text Functions): Move the "word", "wordlist", "words", and
2929 "firstword" functions here, from "File Name Functions".
2930 * make-stds.texi: Update from latest GNU version.
2931 * fdl.texi: (created) Import the latest GNU version.
2933 2002-06-06 Paul D. Smith <psmith@gnu.org>
2935 * variable.c (do_variable_definition): New function: extract the
2936 part of try_variable_definition() that actually sets the value
2937 into a separate function.
2938 (try_variable_definition): Call do_variable_definition() after
2939 parsing the variable definition string.
2940 (define_variable_in_set): Make the name argument const.
2942 * variable.h (enum variable_flavor): Make public.
2943 (do_variable_definition): Create prototype.
2945 * read.c (read_all_makefiles): Create a new built-in variable,
2947 (read_makefile): Add each makefile read in to this variable value.
2949 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2951 * Makefile.DOS.template: Tweak according to changes in the
2952 distribution. Add back the dependencies of *.o files.
2954 * configh.dos.template: Synchronize with config.h.in.
2956 2002-05-09 Paul D. Smith <psmith@gnu.org>
2958 * file.c (file_timestamp_now): Use K&R function declaration.
2960 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2961 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2962 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2963 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2964 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2965 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2966 nlist.n_name is a pointer rather than an array.
2968 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2969 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2970 * configure.in: Use it instead of the old version.
2972 * main.c (main): Prefer setvbuf() to setlinebuf().
2974 2002-05-08 Paul D. Smith <psmith@gnu.org>
2976 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2977 (loadavg_LDADD): Ditto.
2979 2002-04-29 Paul D. Smith <psmith@gnu.org>
2981 * expand.c (recursively_expand_for_file): Rename
2982 recursively_expand() to recursively_expand_for_file() and provide
2983 an extra argument, struct file. If the argument is provided, set
2984 the variable scope to that of the file before expanding.
2985 * variable.h (recursively_expand): Make this a macro that invokes
2986 recursively_expand_for_file() with a NULL file pointer.
2987 * variable.c (target_environment): Call the renamed function and
2988 provide the current file context.
2989 Fixes Debian bug #144306.
2991 2002-04-28 Paul D. Smith <psmith@gnu.org>
2993 Allow $(call ...) user-defined variables to be self-referencing
2994 without throwing an error. Allows implementation of transitive
2995 closures, among other possibly useful things.
2996 Requested by: Philip Guenther <guenther@sendmail.com>
2998 * variable.h (struct variable): Add a new field: exp_count, and
2999 new macros to hold its size and maximum value.
3000 (warn_undefined): Make this a macro.
3001 * variable.c (define_variable_in_set): Initialize it.
3002 * expand.c (recursively_expand): If we detect recursive expansion
3003 of a variable, check the exp_count field. If it's greater than 0
3004 allow the recursion and decrement the count.
3005 (warn_undefined): Remove this (now a macro in variable.h).
3006 * function.c (func_call): Before we expand the user-defined
3007 function, modify its exp_count field to contain the maximum
3008 number of recursive calls we'll allow. After the call, reset it
3011 2002-04-21 Paul D. Smith <psmith@gnu.org>
3013 Modified to use latest autoconf (2.53), automake (1.6.1), and
3014 gettext (0.11.1). We're using gettext's new "external" support,
3015 to avoid including libintl source with GNU make.
3017 * README.cvs: New file. Explain how to build GNU make from CVS.
3019 * configure.in: Modify checking for the system glob library.
3020 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3021 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3022 etc. will manage it correctly). Set an automake conditional
3023 USE_LOCAL_GLOB to decide whether to compile the glob library.
3025 * getloadavg.c (main): Include make.h in the "TEST" program to
3028 * Makefile.am: Remove special rules for loadavg. Replace them
3029 with Automake capabilities for building extra programs.
3031 * signame.c: This file does nothing if the system provide
3032 strsignal(). If not, it implements strsignal(). If the system
3033 doesn't define sys_siglist, then we make our own; otherwise we use
3035 * signame.h: Removed.
3037 * main.c (main): No need to invoke signame_init(). Update copyright.
3039 * ABOUT-NLS: Removed.
3040 * gettext.c: Removed.
3041 * gettext.h: Get a simplified copy from the gettext package.
3043 * i18n/*.po: Moved to po/.
3046 * config/*: Created. Contains package configuration helper files.
3047 * config.guess, config.sub: Moved to config directory.
3049 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3050 Rework to use new-style autoconf features. Use the "external"
3051 mode for gettext. Make the build.sh config file conditional on
3052 whether build.sh.in exists, to avoid autoconf errors.
3053 * acinclude.m4: Removed almost all macros as being obsolete.
3054 Rewrote remaining macros to use AC_DEFINE.
3055 * acconfig.h: Removed.
3057 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3058 conditional to handle customs support. Remove special handling
3061 2002-04-20 Paul D. Smith <psmith@gnu.org>
3063 * function.c (func_call): Don't mark the argument variables $1,
3064 etc. as recursive. They've already been fully expanded so
3065 there's no need to do it again, and doing so strips escaped $'s.
3066 Reported by Sebastian Glita <glseba@yahoo.com>.
3068 * remake.c (notice_finished_file): Walk through double-colon
3069 entries via the prev field, not the next field!
3070 Reported by Greg McGary <greg@mcgary.org>.
3072 * main.c (main): If the user specifies -q and asks for a specific
3073 target which is a makefile, we got an assert. In that case it
3074 turns out we should continue normally instead.
3076 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3078 * i18n/he.po: Installed a new translation.
3080 2002-01-07 Paul D. Smith <psmith@gnu.org>
3082 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3084 2001-12-04 Paul D. Smith <psmith@gnu.org>
3086 * i18n/ja.po: Installed an updated translation.
3088 2001-09-06 Paul Eggert <eggert@twinsun.com>
3090 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3091 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3093 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3095 (main): Get rid of any avoidable limit on stack size.
3097 2001-09-04 Paul D. Smith <psmith@gnu.org>
3099 * i18n/da.po: Installed an updated translation.
3101 2001-08-03 Paul D. Smith <psmith@gnu.org>
3103 * i18n/fr.po: Installed an updated translation.
3104 Resolves Debian bug #106720.
3106 2001-06-13 Paul D. Smith <psmith@gnu.org>

3111 2001-06-11 Paul D. Smith <psmith@gnu.org>
3113 * i18n/ko.po: Installed a new translation.
3115 2001-05-06 Paul D. Smith <psmith@gnu.org>
3117 Modify the EINTR handling.
3119 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3120 the way in which we manage the file descriptor/signal handler race
3121 trap to be more efficient.
3123 2001-05-06 Paul Eggert <eggert@twinsun.com>
3125 Restart almost all system calls that are interrupted, instead
3126 of worrying about EINTR. The lone exception is the read() for
3129 * configure.in (HAVE_SA_RESTART): New macro.
3130 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3131 * main.c (main): Use SA_RESTART instead of the old,
3132 nonstandard SA_INTERRUPT.
3134 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3135 * main.c (bsd_signal): New function or macro,
3136 if the implementation doesn't supply it.
3137 (The bsd_signal function will be in POSIX 1003.1-200x.)
3138 (HANDLESIG): Remove.
3139 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3141 * make.h (EINTR_SET): Remove.
3142 (SA_RESTART): New macro.
3144 * arscan.c (ar_member_touch): Don't worry about EINTR.
3145 * function.c (func_shell): Likewise.
3146 * job.c (reap_children, free_child, new_job): Likewise.
3147 * main.c (main): Likewise.
3148 * remake.c (touch_file, name_mtime): Likewise.
3150 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3151 if fstat failed with errno!=EINTR, the error was ignored.
3153 * job.c (set_child_handler_action_flags): New function.
3154 (new_job): Use it to temporarily clear the SIGCHLD action flags
3155 while reading the token.
3157 2001-05-02 Paul D. Smith <psmith@gnu.org>
3159 * job.c (start_job_command): Don't add define/endef per-line flags
3160 to the top-level flags setting.
3162 2001-04-03 Paul D. Smith <psmith@gnu.org>
3164 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3165 bit on error, so check for odd return values, not non-0 return
3167 (VMS_get_member_info): Calculate the timezone differences correctly.
3168 Reported by John Fowler <jfowler@nyx.net>.
3171 2001-03-14 Paul D. Smith <psmith@gnu.org>
3173 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3174 value before invoking define_variable().
3175 Reported by John Fowler <jfowler@nyx.net>.
3177 2001-02-07 Paul D. Smith <psmith@gnu.org>
3179 * read.c (record_target_var): If we reset the variable due to a
3180 command-line variable setting overriding it, turn off the "append"
3183 2001-01-17 Paul D. Smith <psmith@gnu.org>
3185 * variable.c (lookup_variable) [VMS]: When getting values from the
3186 environment, allocate enough space for the _value_ plus escapes,
3187 not enough space for the name plus escapes :-/.
3188 Reported by John Fowler <jfowler@nyx.net>.
3190 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3191 warnings that make generates, so it doesn't look like an error.
3192 Reported by Karl Berry <karl@gnu.org>.
3195 Fix for PR/2020: Rework appended target-specific variables. I'm
3196 fairly confident this algorithm is finally correct.
3198 * expand.c (allocated_variable_append): Rewrite. Instead of
3199 expanding each appended variable then adding all the expanded
3200 strings together, we append all the unexpanded values going up
3201 through the variable set contexts, then expand the final result.
3202 This behaves just like non-target-specific appended variable
3203 values, while the old way didn't in various corner cases.
3204 (variable_append): New function: recursively append the unexpanded
3205 value of a variable, walking from the outermost variable scope to
3207 * variable.c (lookup_variable): Remove the code that looked up the
3208 variable set list if the found variable was "append". We don't
3210 (lookup_variable_in_set): Make this non-static so we can use it
3212 (try_variable_definition): Use lookup_variable_in_set() rather
3213 than faking out current_variable_set_list by hand (cleanup).
3214 * variable.h: Add a prototype for the now non-static
3215 lookup_variable_in_set().
3217 2000-11-17 Paul D. Smith <psmith@gnu.org>
3219 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3220 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3221 before throwing a fit.
3223 2000-11-17 Paul D. Smith <psmith@gnu.org>
3225 * read.c (readline): CRLF calculations had a hole, if you hit the
3226 buffer grow scenario just right. Reworked the algorithm to avoid
3227 the need for len or lastlen at all. Problem description with
3228 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3230 2000-10-24 Paul D. Smith <psmith@gnu.org>
3232 * gettext.c (SWAP): Declare this with the prototype, otherwise
3233 some systems don't work (non-32-bit? Reported for Cray T3E).
3234 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3236 2000-10-05 Paul D. Smith <psmith@gnu.org>
3238 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3239 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3241 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3243 2000-09-22 Paul D. Smith <psmith@gnu.org>
3245 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3246 parts of the real gettext.h here, and we expect to really include
3247 the real gettext.h later. If we keep this #define, it's ignored.
3249 2000-09-21 Paul D. Smith <psmith@gnu.org>
3251 * main.c (log_working_directory): Rework the text to use complete
3252 sentences, to make life simpler for the translators.
3254 2000-08-29 Paul D. Smith <psmith@gnu.org>
3256 * file.c (remove_intermediates): Print a debug message before we
3257 remove intermediate files, so the user (if she uses -d) knows
3260 2000-08-21 Paul D. Smith <psmith@gnu.org>
3262 * variable.c (try_variable_definition): Change how we handle
3263 target-specific append variable defns: instead of just setting the
3264 value, expand it as an append _but_ only within the current
3265 target's context. Otherwise we lose all but the last value if the
3266 variable is appended more than once within the current target
3267 context. Fixes PR/1831.
3269 2000-08-16 Paul D. Smith <psmith@gnu.org>
3271 * function.c (func_shell): Nul-terminate the buffer before
3272 printing an exec error message (just in case it's not!).
3273 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3275 2000-07-25 Paul D. Smith <psmith@gnu.org>
3277 * job.c (construct_command_argv_internal): Add "~" to the list of
3278 sh_chars[] which disallow optimizing out the shell call.
3280 2000-07-23 Paul Eggert <eggert@twinsun.com>
3282 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3283 supersedes --disable-nsec-timestamps.
3284 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3285 * README: Remove --disable-nsec-timestamps.
3287 * filedef.h (struct file.low_resolution_time): New member.
3288 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3289 * remake.c (update_file_1):
3290 Avoid spurious rebuilds due to low resolution time stamps,
3291 generalizing the earlier code that applied only to archive members.
3292 (f_mtime): Archive members always have low resolution time stamps.
3294 * configure.in: Remove --disable-nsec-timestamps, as this has
3295 been superseded by .LOW_RESOLUTION_TIME.
3297 2000-07-23 Paul Eggert <eggert@twinsun.com>
3299 * configure.in (enable_nsec_timestamps): Renamed from
3300 make_cv_nsec_timestamps, since enable/disable options
3301 shouldn't be cached.
3303 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3304 and Paul Eggert <eggert@twinsun.com>
3306 * file.c (file_timestamp_now):
3307 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3308 so that clock_gettime is not linked unless needed.
3310 * filedef.h (FILE_TIMESTAMP_HI_RES):
3311 Remove definition; "configure" now does this.
3313 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3314 to before high resolution file timestamp check,
3315 since that check now uses uintmax_t.
3316 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3317 high resolution file timestamps.
3318 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3319 so that we don't link in clock_gettime unnecessarily.
3321 2000-07-17 Paul D. Smith <psmith@gnu.org>
3323 * i18n/ja.po: New version of the translation file.
3325 2000-07-07 Paul D. Smith <psmith@gnu.org>
3327 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3328 the offset calculation.
3329 (name_mtime): Replace EINTR test with EINTR_SET macro.
3331 2000-07-07 Paul Eggert <eggert@twinsun.com>
3335 * remake.c (update_file_1):
3336 Avoid spurious rebuilds of archive members due to their
3337 timestamp resolution being only one second.
3338 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3339 the clock's resolution being lower than file timestamps'.
3340 When warning about future timestamps, report only the discrepancy,
3341 not the absolute value of the timestamp and the current time.
3343 * file.c (file_timestamp_now): New arg RESOLUTION.
3344 * filedef.h (file_timestamp_now): Likewise.
3345 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3347 2000-07-05 Paul D. Smith <psmith@gnu.org>
3349 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3350 to listp. Fixes PR/1793.
3352 2000-06-26 Paul Eggert <eggert@twinsun.com>
3354 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3356 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3358 * remake.c (f_mtime): Remove unused var memtime.
3360 2000-06-25 Martin Buchholz <martin@xemacs.org>
3362 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3363 Ran spell-check on make.texinfo.
3365 2000-06-23 Paul D. Smith <psmith@gnu.org>
3367 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3368 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3369 * make.h: Define these macros.
3371 * Version 3.79.1 released.
3373 * configure.in: Add a new option, --disable-nsec-timestamps, to
3374 avoid using sub-second timestamps on systems that support it. It
3375 can lead to problems, e.g. if your makefile relies on "cp -p".
3376 * README.template: Document the issue with "cp -p".
3378 * config.guess, config.sub: Updated.
