3 * read.c (read_all_makefiles): Mark the default makefile dependency
6 2009-10-07 Boris Kolpackov <boris@codesynthesis.com>
8 * read.c (do_undefine): Free the expanded variable name.
10 * commands.c (dep_hash_cmp, set_file_variables): Move the order-only
11 to normal upgrade logic from dep_hash_cmp to set_file_variables.
13 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
15 * dep.h (uniquize_deps): Remove.
17 * read.c (uniquize_deps): Merge into set_file_variables in
19 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
21 * commands.c (set_file_variables): Avoid modifying the dep
22 chain to achieve uniqueness. Fixes savannah bug 25780.
24 * implicit.c (pattern_search): Instead of re-setting all automatic
25 variables for each rule we try, just update $*.
27 2009-10-06 Boris Kolpackov <boris@codesynthesis.com>
29 * variable.h (undefine_variable_in_set): New function declaration.
30 (undefine_variable_global): New macro.
32 * variable.c (undefine_variable_in_set): New function implementation.
34 * read.c (vmodifiers): Add undefine_v modifier.
35 (parse_var_assignment): Parse undefine.
36 (do_undefine): Handle the undefine directive.
37 (eval): Call do_undefine if undefine_v is set.
39 * main.c (.FEATURES): Add a keyword to indicate the new feature.
41 * doc/make.texi (Undefine Directive): Describe the new directive.
43 * NEWS: Add a note about the new directive.
45 2009-10-05 Boris Kolpackov <boris@codesynthesis.com>
47 * implicit.c (pattern_search): Initialize file variables only
48 if we need to parse a rule that requires the second expansion.
50 2009-10-03 Paul Smith <psmith@gnu.org>
52 * make.h: Include <alloca.h> even on systems where __GNUC__ is
53 defined. Not sure why it was done the other way.
54 Requested by David Boyce <dsb@boyski.com>.
56 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
58 * dep.h (dep): Add the DONTCARE bitfield.
60 * filedef.h (file):Add the NO_DIAG bitfield.
62 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
63 not struct file (a file can be a dependency of many targets,
64 some don't care, some do).
66 * remake.c (update_goal_chain): Propagate DONTCARE from struct
67 dep to struct file before updating the goal and restore it
69 (update_file): Don't prune the dependency graph if this target
70 has failed but the diagnostics hasn't been issued.
71 (complain): Scan the file's dependency graph to find the file
72 that caused the failure.
73 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
74 whether to print diagnostics.
76 Fixes Savannah bugs #15110, #25493, #12686, and #17740.
78 2009-09-28 Paul Smith <psmith@gnu.org>
80 * doc/make.texi (Pattern Intro): Move the match algorithm
81 discussion into the "Pattern Match" node.
82 (Pattern Match): Expand on the pattern rule matching algorithm.
84 2009-09-28 Andreas Buening <andreas.buening@nexgo.de>
86 * job.c (construct_command_argv_internal) [OS2]: Don't eat too
87 much of the command line on a single pass.
89 2009-09-28 Boris Kolpackov <boris@codesynthesis.com>
91 * varible.c (create_pattern_var): Insert variables into the
92 PATTERN_VARS list in the shortest patterns first order.
94 * implicit.c (tryrule): Add STEMLEN and ORDER members. These are
95 used to sort the rules.
96 (stemlen_compare): Compare two tryrule elements.
97 (pattern_search): Sort the rules so that they are in the shortest
100 * main.c (.FEATURES): Add a keyword to indicate the new behavior.
102 * doc/make.texi (Pattern-specific Variable Values): Describe the
103 new pattern-specific variables application order.
104 (Introduction to Pattern Rules): Describe the new pattern rules
107 * NEWS: Add a note about the new behavior.
109 2009-09-27 Paul Smith <psmith@gnu.org>
111 * doc/make.texi (Double-Colon): Mention that pattern rules with
112 double-colons have a different meaning. Savannah bug #27497.
114 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
116 * configh.dos.template: Remove unconditional definition of
117 SYS_SIGLIST_DECLARED.
118 Include <sys/version.h> because ports of GCC 4.3.0 and later no
119 longer include it, so macros like __DJGPP_MINOR__ are no longer
120 defined automatically.
122 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
123 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
124 instead of using the hardcoded ones.
125 (SUBDIRS): doc subdir added.
126 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
127 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
128 create html formated docs. texi2html may not be ported to DOS.
129 (make.info, make.dvi, make.ps, make.html): Make targets depend on
131 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
132 -I switch to look in ./ instead of ./doc.
133 (html): Target depend on html-recursive instead of make_1.html.
134 (make_1.html): Removed.
135 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
136 (all-recursive): Allow for more than one subdir in the build
138 (mostlyclean-recursive, clean-recursive, distclean-recursive)
139 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
140 (tags-recursive): Allow for more than one subdir in the build
142 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
143 targets. Enter into doc/ to produce the targets.
144 (all-am): $(INFO_DEPS) replaced by info.
146 2009-09-26 Paul Smith <psmith@gnu.org>
148 * read.c (record_files): Use free_ns() to free struct nameseq.
151 * rule.c (freerule): Use free_dep_chain().
153 * read.c (record_files): Free FILENAMES chain for implicit rules.
154 (eval): Static pattern targets go into the string cache.
156 * function.c (string_glob): Free NAME in the nameseq chain.
158 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
160 * implicit.c (pattern_search): Terminate early if we haven't
161 found any rules to try (performance improvement).
163 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
165 * implicit.c (pattern_search): Merge three parallel arrays,
166 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
167 of struct TRYRULE. In the old version the latter two arrays
168 had insufficient length.
170 2009-09-24 Paul Smith <psmith@gnu.org>
172 * implicit.c (pattern_search): Add back support for order-only
173 prerequisites for secondary expansion implicit rules, that were
174 accidentally dropped. If we find a "|", enable order-only mode
175 and set IGNORE_MTIME on all deps that are seen afterward.
176 (pattern_search): Fix memory leaks: for intermediate files where
177 we've already set the file variable and pattern variable sets, be
178 sure to either save or free them as appropriate.
180 2009-09-23 Paul Smith <psmith@gnu.org>
182 Rework the way secondary expansion is stored, for efficiency.
183 This changes secondary expansion so that ONLY WHEN we know we have
184 a possibility of needing secondary expansion, do we defer the
185 secondary expansion. This means more parsing the deps but we use
186 a lot less memory (due to the strcache). Also, this fixes
189 * read.c (eval): Don't parse the dep string here anymore.
190 (record_files): Take the dep argument as an unparsed string. If
191 secondary expansion is enabled AND the prereq string has a '$' in
192 it, then set NEED_2ND_EXPANSION and keep the entire string.
193 Otherwise, parse the dep string here to construct the dep list
194 with the names in the strcache.
196 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
197 duplicate the name string (others are in the strcache).
199 * implicit.c: Remove struct idep and free_idep_chain(): unused.
200 (struct patdeps): New structure to store prereq information.
201 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
202 which prerequisites need expansion, and expand only those.
204 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
205 and enter_prereqs(). split_prereqs() takes a fully-expanded string
206 and splits it into a DEP list, handling order-only prereqs.
207 (enter_prereqs): This function enters a list of DEPs into the file
208 database. If there's a stem defined, expand any pattern chars.
209 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
210 set. Use the above functions.
211 (snap_deps): Only perform second expansion on prereqs that need it,
212 as defined by the NEED_2ND_EXPANSION flag.
213 (print_prereqs): New function to print the prereqs
214 (print_file): Call print_prereqs() rather than print inline.
216 * hash.h (STRING_COMPARE): Take advantage of strcache() by
218 (STRING_N_COMPARE): Ditto.
219 (ISTRING_COMPARE): Ditto.
221 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
222 (parse_file_seq): Return void*
223 * read.c (parse_file_seq): Return void*.
224 (eval): Invoke macroized version of parse_file_seq()
225 * default.c (set_default_suffixes): Ditto.
226 * file.c (split_prereqs): Ditto.
227 * function.c (string_glob): Ditto.
228 * main.c (main): Ditto.
229 * rule.c (install_pattern_rule): Ditto.
231 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
233 2009-09-16 Paul Smith <psmith@gnu.org>
235 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
237 * dep.h: Create alloc_dep() / free_dep() macros.
239 * implicit.c (pattern_search): Take advantage of the new
240 parse_file_seq() to add the directory prefix to each prereq.
242 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
243 all. Avoid reversing chains. Support adding prefixes.
244 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
245 cached/non-cached results.
246 (eval): Remove multi_glob() & invoke new parse_file_seq().
247 * rule.c (install_pattern_rule): Ditto.
248 * main.c (main): Ditto.
249 * implicit.c (pattern_search): Ditto.
250 * function.c (string_glob): Ditto.
251 * file.c (parse_prereqs): Ditto.
252 * default.c (set_default_suffixes): Ditto.
254 * variable.c (parse_variable_definition): Don't run off the end of
255 the string if it ends in whitespace (found with valgrind).
257 * commands.c (set_file_variables): Keep space for all targets in
258 $? if -B is given (found with valgrind).
260 2009-09-15 Paul Smith <psmith@gnu.org>
262 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
263 (xcalloc): Add new function.
264 * make.h: New declarations.
266 * ar.c (ar_glob_match): New calling method for concat().
267 * main.c (main): Ditto.
268 (decode_env_switches): Ditto.
269 * read.c (eval_makefile): Ditto.
270 (tilde_expand): Ditto.
271 (parse_file_seq): Ditto.
272 * variable.c (target_environment): Ditto.
273 (sync_Path_environment): Ditto.
275 * ar.c (ar_glob_match): Use xcalloc().
276 * dir.c (file_impossible): Ditto.
277 * file.c (enter_file): Ditto.
278 * job.c (new_job): Ditto.
279 * read.c (parse_file_seq): Ditto.
280 * vmsfunctions.c (opendir): Ditto.
282 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
284 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
285 inside the loop that looks up environment for PATH.
287 2009-08-31 Eli Zaretskii <eliz@gnu.org>
289 * function.c (windows32_openpipe): Update envp after calling
290 sync_Path_environment.
292 2009-08-02 Paul Smith <psmith@gnu.org>
294 * remake.c (notice_finished_file): Ensure file->cmds is not null
295 before looping through them. Fixes Savannah bug #21824.
297 * doc/make.texi (Wildcard Examples): Clarify when objects is
298 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
299 (Include): Clarify the behavior of -include.
300 Fixes Savannah bug #18963.
302 2009-08-01 Paul Smith <psmith@gnu.org>
304 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
305 etc. come on the command line. Fixes Savannah bug #27093.
307 * expand.c (expand_argument): If the argument is large enough use
308 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
310 * variable.c (do_variable_definition): Avoid using alloca() to
311 hold values, which can be large. Fixes Savannah bug #23960.
313 * job.c (new_job): Use memmove() instead of strcpy() since both
314 pointers are in the same memory block. Fixes Savannah bug #27148.
315 Patch by Petr Machata.
317 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
319 * job.c (construct_command_argv_internal): Add "ulimit" and
320 "unset" to the sh_cmds for Unixy shells.
322 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
324 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
325 that set make_cv_sys_gnu_glob, so they are also correctly set
326 when the cache has been populated before.
328 2009-07-04 Eli Zaretskii <eliz@gnu.org>
330 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
331 exist, as realpath(3) does where it's supported.
333 2006-07-04 Eli Zaretskii <eliz@gnu.org>
335 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
336 (abspath): Support systems that define HAVE_DOS_PATHS (have
337 drive letters in their file names). Use IS_PATHSEP instead of a
338 literal '/' comparison. Fixes Savannah bug #26886.
340 2009-06-14 Paul Smith <psmith@gnu.org>
342 * remake.c (update_file_1): Remember the original file we marked
343 as updating, so we can clear that flag again. If we find a target
344 via vpath, FILE might change.
345 (check_dep): Ditto. Fixes Savannah bug #13529.
346 Patch by Reid Madsen <reid.madsen@tek.com>.
348 2009-06-13 Paul Smith <psmith@gnu.org>
350 * doc/make.texi (MAKEFILES Variable): Be explicit that files
351 included by MAKEFILES cannot give default goals.
352 * read.c (eval): If set_default is not set, pass the no-default-goal
353 value when we read included makefiles. Fixes Savannah bug #13401.
355 * ar.c (ar_name): Ensure that targets with empty parens aren't
356 considered archive member references: archive members must have a
357 non-empty "member" string. Fixes Savannah bug #18435.
359 * function.c (string_glob): Rely on multi_glob() to determine
360 whether files exist or not. Remove call to file_exists_p() which
361 is not always correct. Fixes Savannah bug #21231.
362 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
363 then only files that really exist will be returned.
364 * dep.h: Add new argument to multi_glob().
365 * rule.c (install_pattern_rule): Ditto.
366 * read.c (eval): Ditto.
367 * main.c (main): Ditto.
368 * implicit.c (pattern_search): Ditto.
369 * file.c (parse_prereqs): Ditto.
370 * default.c (set_default_suffixes): Ditto.
372 2009-06-09 Paul Smith <psmith@gnu.org>
374 * commands.c (set_file_variables): If always_make_flag is set,
375 always add the prereq to $?. Fixes Savannah bug #17825.
377 * remake.c (update_file_1): When rebuilding deps of FILE, also try
378 to rebuild the deps of all the also_make targets for that file.
379 Fixes Savannah bug #19108.
381 * implicit.c (pattern_search): Undo test for is_target, added by
382 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
383 Rule Search Algorithm". Fixes Savannah bug #17752.
385 * main.c (clean_jobserver): Clear the jobserver_fds options and
386 set job_slots to the default when we clean up.
387 (define_makeflags): Return the new MAKEFLAGS value.
388 (main): Reset MAKEFLAGS in the environment when we re-exec.
389 Fixes Savannah bug #18124.
391 2009-06-08 Paul Smith <psmith@gnu.org>
393 * read.c (eval): Collapse continuations post-semicolon on target-
394 specific variables. Fixes Savannah bug #17521.
396 2009-06-07 Paul Smith <psmith@gnu.org>
398 * job.c (reap_children): For older systems without waitpid() (are
399 there any of these left?) run wait(2) inside EINTRLOOP to handle
400 EINTR errors. Fixes Savannah bug #16401.
402 * (various): Debug message cleanup. Fixes Savannah bug #16469.
404 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
406 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
407 not the end, to catch second expansion $(eval ...) defining new
408 target/prereq relationships during snap_deps.
409 Fixes Savannah bug #24622.
411 * read.c (record_files): The second-expansion "f->updating" hack
412 was not completely correct: if assumed that the target with
413 commands always had prerequisites; if one didn't then the ordering
414 was messed up. Fixed for now to use f->updating to decide whether
415 to preserve the last element in the deps list... but this whole
416 area of constructing and reversing the deps list is too confusing
417 and needs to be reworked. Fixes Savannah bug #21198.
419 2009-06-06 Paul Smith <psmith@gnu.org>
421 * hash.c (hash_insert): Remove useless test for NULL.
422 Fixes Savannah bug #21823.
424 * make.h: Move SET_STACK_SIZE determination to make.h.
425 * main.c (main): New global variable, STACK_LIMIT, holds the
426 original stack limit when make was started.
427 * job.c (start_job_command): Reset the stack limit, if we changed it.
428 Fixes Savannah bug #22010.
430 * remake.c (check_dep): Only set the target's state to not-started
431 if it's not already running. Found this while testing -j10 builds
432 of glibc: various targets were being rebuilt multiple times.
433 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
436 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
437 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
440 2009-06-04 Paul Smith <psmith@gnu.org>
442 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
444 * maintMakefile: Modify access of config and gnulib Savannah
445 modules to use GIT instead of CVS.
447 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
448 Fixes Savannah bug #24655.
450 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
451 this can happen during some invocations of $(eval ...) for example.
452 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
454 2009-06-02 Paul Smith <psmith@gnu.org>
456 * configure.in: Check for fileno()
457 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
458 for the makefile file so invocations of $(shell ...) don't inherit it.
459 Fixes Savannah bug #24277.
461 2009-06-01 Paul Smith <psmith@gnu.org>
463 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
464 expansion was handled incorrectly. Rework the default goal
465 handling to save the variable only. Remove default_goal_file and
467 * read.c (eval): Check default_goal_var, not default_goal_name.
468 * read.c (record_target_var): Don't check default_goal_file here.
470 2009-05-31 Paul Smith <psmith@gnu.org>
472 * main.c (main): Expand the .DEFAULT_GOAL variable before using
473 it, and if the multi_glob() returns nothing (say it expanded to
474 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
476 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
477 $(and ..) to the reference. Fixes Savannah bug #25694.
479 * make.1: Be clear that some recipes will be executed even with -n.
480 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
482 * doc/make.texi (Override Directive): Make more clear how
483 overrides and appends interact.
484 Elucidates part of Savannah bug #26207.
486 * read.c (record_target_var): Don't reset the origin on
487 target-specific variables; try_variable_definition() will handle
488 this correctly. Fixes Savannah bug #26207.
490 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
491 Fixes Savannah bug #25712.
493 * implicit.c (pattern_search): Keep a pointer to the beginning of
494 the filename and save that instead of the constructed pointer.
495 Fixes Savannah bug #26593.
496 Patch by Mark Seaborn <mrs@mythic-beasts.com>
498 2009-05-30 Paul Smith <psmith@gnu.org>
500 * doc/make.texi (Multi-Line): Add a description of the new abilities
501 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
502 "command sequence" vs. "recipe" syntax.
503 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
504 after a define, to create variables with those flavors.
506 2009-05-25 Paul Smith <psmith@gnu.org>
508 Reworked the parser for variable assignments to allow multiple
509 modifiers, and in any order. Also allows variable and
510 prerequisites to be modifier names ('export', 'private', etc.)
512 * NEWS: Add notes about user-visible changes.
514 * read.c (struct vmodifiers): Remember what modifiers were seen.
515 (parse_var_assignment): New function to parse variable assignments.
516 (eval): Call the new function. Handle variable assignments earlier.
518 * variable.c (parse_variable_definition): Only parse; don't create var.
519 (assign_variable_definition): Call parse, then create the var.
521 2009-05-24 Paul Smith <psmith@gnu.org>
523 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
524 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
526 2009-03-14 Eli Zaretskii <eliz@gnu.org>
528 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
529 Fixes Savannah bug #25412.
531 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
532 prototype for xmalloc.
533 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
534 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
535 Loop over an array of extensions, instead of duplicating the same
536 code inline. Use SearchPath followed by CreateFile, instead of
537 the obsolete OpenFile. Fixes Savannah bug #17277.
538 (process_begin): Find $(PATH) in `envp', and pass a pointer to it

670 2007-10-12 Eli Zaretskii <eliz@gnu.org>
672 * variable.c (do_variable_definition): Allow $(SHELL) to expand to

734 2007-08-15 Paul Smith <psmith@gnu.org>

800 Dave Korn <dave.korn@artimi.com>
802 2007-05-08 Paul Smith <psmith@gnu.org>
804 Fix Savannah bug #19656:
806 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
808 * make.h: Change all case-insensitive string compares to use
809 strcasecmp() (from POSIX). If we don't have that but do have one
810 of the others, define strcasecmp to be one of those instead. If
811 we don't have any, declare a prototype for our own version.
813 * misc.c (strcasecmp): Use this if we can't find any native
814 case-insensitive string comparison function.
815 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
816 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
818 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
819 strcasecmp() instead of stricmp().
820 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
821 instead of strcmpi().
822 * acinclude.m4: Remove the strcasecmp() check from here.
824 2007-03-21 Paul Smith <psmith@gnu.org>
826 * configure.in: Don't turn on case-insensitive file system support
827 if --disable-... is given. Fixes Savannah bug #19348.
829 2007-03-19 Paul Smith <psmith@gnu.org>
831 * ALL: Use the strcache for all file name strings, or other
832 strings which we will never free. The goal is to save memory by
833 avoiding duplicate copies of strings. However, at the moment this
834 doesn't save much memory in most situations: due to secondary
835 expansion we actually save prerequisite lists twice (once before
836 the secondary expansion, and then again after it's been parsed
837 into individual file names in the dep list). We will resolve this
838 in a future change, by doing the parsing up-front for targets
839 where secondary expansion is not set.
841 Moving things into the strcache also allows us to use const
842 pointers in many more places.
844 2007-01-03 Paul Smith <psmith@gnu.org>
846 * make.h (ENULLLOOP): Reset errno after each failed invocation of
847 the function, not just the first. Fixes Savannah bug #18680.
849 2006-11-18 Paul Smith <psmith@gnu.org>
851 * strcache.c (strcache_add_len): Don't allocate a new buffer
852 unless the string is not already nil-terminated. Technically this
853 is a violation of the standard, since we may be passed an array
854 that is not long enough to test one past. However, in make this
855 is never true since we only use nil-terminated strings or
858 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
860 * main.c: New global cmd_prefix, defaults to '\t'.
861 * job.c (construct_command_argv_internal): Use cmd_prefix instead
865 (dir_contents_file_exists_p): Check for an error return from
866 readdir(), just in case.
868 * commands.c: Constified.
869 * default.c: Constified.
870 * expand.c: Constified.
871 * function.c: Partial constification.
872 * variable.c: Partial constification.

887 2006-10-21 Paul Smith <psmith@gnu.org>
890 * arscan.c: Constified.
892 2006-09-30 Paul Smith <psmith@gnu.org>
894 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
895 point to lastword since the example was updated.
896 Fixes Savannah bug #16304.

900 variable references or function calls.
901 Fixes Savannah bug #16577.

903 Fixes Savannah bug #17701.

1086 Fixes Savannah bug #15913.
1088 2006-03-09 Paul Smith <psmith@gnu.org>
1090 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1091 listed non-existent files as changed. Turns out there's a bug in
1092 the Linux kernel builds which means that this change causes
1093 everything to rebuild every time. We will re-introduce this fix
1094 in the next release, to give them time to fix their build system.
1095 Fixes Savannah bug #16002.
1096 Introduces Savannah bug #16051.
1098 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1099 we *don't* find UNIX "/".
1100 Reported by David Ergo <david.ergo@alterface.com>
1102 2006-03-04 Eli Zaretskii <eliz@gnu.org>
1104 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
1105 locator function find_and_set_default_shell if SHELL came from the
1108 2006-02-20 Paul D. Smith <psmith@gnu.org>
1110 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1111 to be null; don't core in that case.
1113 2006-02-19 Paul D. Smith <psmith@gnu.org>
1115 * commands.c (set_file_variables): Realloc, not malloc, the static
1116 string values to avoid memory leaks.
1118 * expand.c (recursively_expand_for_file): Only set reading_file to
1119 an initialized value.
1121 * implicit.c (pattern_search): We need to make a copy of the stem
1122 if we get it from an intermediate dep, since those get freed.
1124 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1126 (enter_file) [VMS]: Ditto.
1127 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1129 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1131 * job.c (construct_command_argv_internal): Fix last change.
1133 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1134 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1135 the calls to _beginthreadex.
1137 * expand.c (recursively_expand_for_file): Initialize `save' to
1138 prevent compiler warnings.
1140 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1142 * job.c (construct_command_argv_internal): Don't create a temporary
1143 script/batch file if we are under -n. Call _setmode to switch the
1144 script file stream to text mode.
1146 2006-02-17 Paul D. Smith <psmith@gnu.org>
1148 * variable.c (merge_variable_set_lists): Don't try to merge the
1149 global_setlist. Not only is this useless, but it can lead to
1150 circularities in the linked list, if global_setlist->next in one
1151 list gets set to point to another list which also ends in
1153 Fixes Savannah bug #15757.
1155 2006-02-15 Paul D. Smith <psmith@gnu.org>
1157 Fix for Savannah bug #106.
1159 * expand.c (expanding_var): Keep track of which variable we're
1160 expanding. If no variable is being expanded, it's the same as
1162 * make.h (expanding_var): Declare it.
1163 * expand.c (recursively_expand_for_file): Set expanding_var to the
1164 current variable we're expanding, unless there's no file info in
1165 it (could happen if it comes from the command line or a default
1166 variable). Restore it before we exit.
1167 * expand.c (variable_expand_string): Use the expanding_var file
1168 info instead of the reading_file info.
1169 * function.c (check_numeric): Ditto.
1171 (func_wordlist): Ditto.
1172 (func_error): Ditto.
1173 (expand_builtin_function): Ditto.
1174 (handle_function): Ditto.
1176 2006-02-14 Paul D. Smith <psmith@gnu.org>
1178 * read.c (eval): Even if the included filenames expands to the
1179 empty string we still need to free the allocated buffer.
1181 * implicit.c (pattern_search): If we allocated a variable set for
1182 an impossible file, free it.
1183 * variable.c (free_variable_set): New function.
1184 * variable.h: Declare it.
1186 * read.c (read_all_makefiles): Makefile names are kept in the
1187 strcache, so there's never any need to alloc/free them.
1190 * main.c (main): Add "archives" to the .FEATURES variable if
1191 archive support is enabled.
1192 * doc/make.texi (Special Variables): Document it.
1194 2006-02-13 Paul D. Smith <psmith@gnu.org>
1196 * implicit.c (pattern_search): Add checking for DOS pathnames to
1197 the pattern rule target LASTSLASH manipulation.
1198 Fixes Savannah bug #11183.

1202 * (ALL FILES): Updated copyright and license notices.
1204 2006-02-10 Paul D. Smith <psmith@gnu.org>
1206 A new internal capability: the string cache is a read-only cache
1207 of strings, with a hash table interface for fast lookup. Nothing
1208 in the cache will ever be freed, so there's no need for reference
1209 counting, etc. This is the beginning of a full solution for
1210 Savannah bug #15182, but for now we only store makefile names here.
1212 * strcache.c: New file. Implement a read-only string cache.
1213 * make.h: Add prototypes for new functions.
1214 * main.c (initialize_global_hash_tables): Initialize the string cache.
1215 (print_data_base): Print string cache stats.
1216 * read.c (eval_makefile): Use the string cache to store makefile
1217 names. Rewrite the string allocation to be sure we free everything.
1219 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1221 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1222 directory time stamp didn't change, except on FAT filesystems.
1223 Suggested by J. David Bryan <jdbryan@acm.org>.
1225 2006-02-09 Paul D. Smith <psmith@gnu.org>
1227 * function.c (func_or): Implement a short-circuiting OR function.
1228 (func_and): Implement a short-circuiting AND function.
1229 (function_table_init): Update the table with the new functions.
1230 * doc/make.texi (Conditional Functions): Changed the "if" section
1231 to one on general conditional functions. Added documentation for
1232 $(and ...) and $(or ...) functions.
1233 * NEWS: Note new $(and ...) and $(or ...) functions.
1235 2006-02-08 Boris Kolpackov <boris@kolpackov.net>
1237 * job.h (struct child): Add the dontcare bitfield.
1238 * job.c (new_job): Cache dontcare flag.
1239 * job.c (reap_children): Use cached dontcare flag instead of the
1240 one in struct file. Fixes Savannah bug #15641.
1242 2006-02-06 Paul D. Smith <psmith@gnu.org>
1244 * vpath.c (selective_vpath_search): If the file we find has a
1245 timestamp from -o or -W, use that instead of the real time.
1246 * remake.c (f_mtime): If the mtime is a special token from -o or
1247 -W, don't overwrite it with the real mtime.
1248 Fixes Savannah bug #15341.
1250 Updates from Markus Mauhart <qwe123@chello.at>:
1252 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1253 (process_signal, process_last_err, process_exit_code): Manage
1254 invalid handle values.
1255 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1256 manage invalid handles; remove them.
1257 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1258 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1259 * README.cvs: Updates for building from CVS.
1261 2006-02-05 Paul D. Smith <psmith@gnu.org>
1263 * file.c (enter_file): Keep track of the last double_colon entry,
1264 to avoid walking the list every time we want to add a new one.
1265 Fixes Savannah bug #15533.
1266 * filedef.h (struct file): Add a new LAST pointer.
1268 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1269 the comparison. For 64-bits systems the result of the subtraction
1270 might not fit into an int. Use comparison instead.
1271 Fixes Savannah bug #15534.
1273 * doc/make.texi: Update the chapter on writing commands to reflect
1274 the changes made in 3.81 for backslash/newline and SHELL handling.
1276 2006-02-01 Paul D. Smith <psmith@gnu.org>
1278 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1279 variable st is not used when it's not initialized.

1294 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1296 * remake.c (update_goal_chain): Set g->changed instead of
1297 incrementing it, as it is only 8-bit wide, and could overflow if
1298 many commands got started in update_file.
1300 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1302 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
1303 MAXIMUM_WAIT_OBJECTS.
1304 (process_wait_for_any_private): Change dimension of handles[]
1305 array to MAXIMUM_WAIT_OBJECTS.
1306 (process_used_slots): New function.
1307 (process_register): Don't register more processes than the
1308 available number of slots.
1309 (process_easy): Don't start new processes if all slots are used up.
1311 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
1312 are already more children than sub_proc.c can handle, behave as if
1313 the load were too high.
1314 (start_job_command): Fix a typo in error message when process_easy
1317 2006-01-14 Eli Zaretskii <eliz@gnu.org>
1319 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
1320 the shell is not sh.exe.
1322 * job.c (create_batch_file): Renamed from create_batch_filename;
1323 all callers changed. Don't close the temporary file; return its
1324 file descriptor instead. New arg FD allows to return the file
1326 (construct_command_argv_internal): Use _fdopen instead of fopen to
1327 open the batch file.
1329 2006-01-04 Paul D. Smith <psmith@gnu.org>
1331 * readme.vms: Updates for case-insensitive VMS file systems from
1332 Hartmut Becker <Hartmut.Becker@hp.com>.
1333 * dir.c (vms_hash): Ditto.
1334 * vmsify.c (copyto): Ditto.

1352 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
1353 disable warnings for MSC.
1354 Patch by Rob Tulloh <rtulloh@yahoo.com>.
1356 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1358 * doc/make.texi (Execution): Add a footnote about changes in
1359 handling of backslash-newline sequences. Mention the differences
1360 on MS-DOS and MS-Windows.
1362 * NEWS: More details about building the MinGW port and a pointer
1363 to README.W32. Fix the section name that describes the new
1364 backward-incompatible processing of backslash-newline sequences.
1365 The special processing of SHELL set to "cmd" is only relevant to
1366 MS-Windows, not MS-DOS.
1368 2005-12-17 Eli Zaretskii <eliz@gnu.org>
1370 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
1371 to DWORD, to avoid compiler warnings.
1372 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
1373 use %ld in format, to avoid compiler warnings.
1375 * doc/make.texi (Special Targets): Fix a typo.
1376 (Appending): Fix cross-reference to Setting.
1377 (Special Variables, Secondary Expansion, File Name Functions)

1387 * read.c (record_target_var): Initialize variable's export field
1388 with v_default instead of leaving it "initialized" by whatever
1389 garbage happened to be on the heap.

1393 * make.1: Fix some display errors and document all existing options.
1394 Patch provided by Mike Frysinger <vapier@gentoo.org>.
1396 2005-12-11 Paul D. Smith <psmith@gnu.org>
1398 * implicit.c (pattern_search): If 2nd expansion is not set for
1399 this implicit rule, replace the pattern with the stem directly,
1400 and don't re-expand the variable list. Along with the other
1401 .SECONDEXPANSION changes below, fixes bug #13781.
1403 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
1405 * implicit.c (pattern_search): Mark other files that this rule
1406 builds as targets so that they are not treated as intermediates
1407 by the pattern rule search algorithm. Fixes bug #13022.
1409 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
1411 * remake.c (notice_finished_file): Propagate the change of
1412 modification time to all the double-colon entries only if

1431 * read.c (record_files): Don't set deps flags if there are no deps.
1432 * maintMakefile: We only need to build the templates when we are
1433 creating a distribution, so don't do it for "all".
1435 2005-10-24 Paul D. Smith <psmith@gnu.org>
1437 Make secondary expansion optional: its enabled by declaring the
1438 special target .SECONDEXPANSION.
1440 * NEWS: Update information on second expansion capabilities.
1441 * doc/make.texi (Secondary Expansion): Document the
1442 .SECONDEXPANSION special target and its behavior.

1444 prerequisite list was found in a static pattern rule.
1445 (free_dep_chain): Declare a prototype.
1446 * file.c (parse_prereqs): New function: break out some complexity
1448 (expand_deps): If we aren't doing second expansion, replace % with
1449 the stem for static pattern rules. Call the new function.
1450 * filedef.h (parse_prereqs): Declare a prototype.
1451 * implicit.c (pattern_search): Initialize the new staticpattern
1453 * main.c (second_expansion): Declare a global variable to remember
1454 if the special target has been seen. Initialize the new
1455 staticpattern field for prerequisites.
1456 * make.h: Extern for second_expansion.
1457 * misc.c (free_dep_chain): New function: frees a struct dep list.
1458 * read.c (read_all_makefiles): Initialize the staticpattern field.
1459 (eval_makefile): Ditto.
1460 (record_files): Check for the .SECONDEXPANSION target and set
1461 second_expansion global if it's found.
1462 Use the new free_dep_chain() instead of doing it by hand.
1463 Set the staticpattern field for prereqs of static pattern targets.
1465 2005-10-16 Paul D. Smith <psmith@gnu.org>
1467 * main.c (main): Set CURDIR to be a file variable instead of a
1468 default, so that values of CURDIR inherited from the environment
1469 won't override the make value.
1471 2005-09-26 Paul D. Smith <psmith@gnu.org>
1473 * job.c (construct_command_argv_internal): If the line is empty
1474 remember to free the temporary argv strings.
1477 2005-09-16 Paul D. Smith <psmith@gnu.org>
1479 * job.c (start_job_command): The noerror flag is a boolean (single
1480 bit); set it appropriately.
1481 Reported by Mark Eichin <eichin@metacarta.com>
1483 2005-08-29 Paul D. Smith <psmith@gnu.org>
1485 * function.c (func_error): On Windows, output from $(info ...)
1486 seems to come in the wrong order. Try to force it with fflush().
1488 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1490 * read.c (record_files): Move code that sets stem for static
1491 pattern rules out of the if (!two_colon) condition so it is
1492 also executed for two-colon rules. Fixes Savannah bug #13881.
1494 2005-08-08 Paul D. Smith <psmith@gnu.org>
1496 * make.h: Don't test that __STDC__ is non-0. Some compilers
1497 (Windows for example) set it to 0 to denote "ISO C + extensions".
1500 2005-08-07 Paul D. Smith <psmith@gnu.org>
1502 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1503 conditional (slightly different version of a fix from Eli).
1505 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1506 If make is running in parallel without -k and two jobs die in a
1507 row, but not too close to each other, then make will quit without
1508 waiting for the rest of the jobs to die.
1510 * main.c (die): Don't reset err before calling reap_children() the
1511 second time: we still want it to be in the error condition.
1512 * job.c (reap_children): Use a static variable, rather than err,
1513 to control whether or not the error message should be printed.
1515 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1517 * w32/subproc/sub_proc.c: Include signal.h.
1518 (process_pipe_io, process_file_io): Pass a pointer to a local
1519 DWORD variable to GetExitCodeProcess. If the exit code is
1520 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1522 * job.c [WINDOWS32]: Include windows.h.
1523 (main_thread) [WINDOWS32]: New global variable.
1524 (reap_children) [WINDOWS32]: Get the handle for the main thread
1525 and store it in main_thread.
1527 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1528 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1529 doing anything else. When we are done, close the main thread
1530 handle and exit with status 130.
1532 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1534 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1537 * main.c (find_and_set_default_shell): If found a DOSish shell,
1538 set sh_found and the value of default_shell, and report the
1539 findings in debug mode.
1541 * job.c (construct_command_argv_internal): Check unixy_shell, not
1542 no_default_sh_exe, to decide whether to use Unixy or DOSish
1545 * README.W32: Update with info about the MinGW build.
1547 * build_w32.bat: Support MinGW.
1549 * w32/subproc/build.bat: Likewise.
1551 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1552 printing DWORD args.
1554 * function.c (windows32_openpipe): Fix format strings for printing
1557 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1559 (start_job_command): Fix format string for printing the result of
1561 (start_job_command) [WINDOWS32]: Do not define.
1562 (exec_command): Fix format string for printing HANDLE args.
1564 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1565 to avoid compiler warnings.
1566 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1567 (Note: some of these fixes were submitted independently by J. Grant)
1569 2005-07-30 J. Grant <jg@jguk.org>
1571 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1572 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1573 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1575 2005-07-15 Paul Smith <psmith@gnu.org>
1577 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1578 we don't have a POSIX shell, then revert to the old
1579 backslash-newline behavior (where they are stripped).
1582 2005-07-08 Paul D. Smith <psmith@gnu.org>
1584 * config.h.W32.template: Reorder to match the standard config.h,
1585 for easier comparisons.
1586 From J. Grant <jg@jguk.org>
1588 * maintMakefile: Remove .dep_segment before overwriting it, in
1589 case it's not writable or noclobber is set.
1590 * expand.c (variable_expand_string): Cast result of pointer
1591 arithmetic to avoid a warning.
1592 * main.c (switches): Add full-fledged final initializer.
1594 2005-07-06 Paul D. Smith <psmith@gnu.org>
1596 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1597 * signame.c (strsignal): If we found _sys_siglist[] or
1598 __sys_siglist[] use those instead of sys_siglist[].

1603 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1604 globfree(); set up to use the GNU versions.
1605 From Martin Zinser <zinser@zinser.no-ip.info>
1607 2005-07-03 Paul D. Smith <psmith@gnu.org>
1609 From J. Grant <jg@jguk.org>:
1611 * README.W32.template: Update the Windows and tested MSVC versions.
1612 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1613 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1614 * build_w32.bat: Ditto.
1615 * w32/subproc/build.bat: Ditto.
1617 2005-06-28 Paul D. Smith <psmith@gnu.org>
1619 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1620 declaration was checked but not present.
1622 2005-06-27 Paul D. Smith <psmith@gnu.org>
1624 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1625 to unsigned long. Fixes Savannah bug #13550.
1627 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1628 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1629 Fixes Savannah bug #13551.
1631 2005-06-26 Paul D. Smith <psmith@gnu.org>
1633 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1634 it if ANSI_STRING is not set.
1636 2005-06-25 Paul D. Smith <psmith@gnu.org>
1638 * read.c (eval): If no filenames are passed to any of the
1639 "include" variants, don't print an error.
1640 * doc/make.texi (Include): Document this.
1641 Fixes Savannah bug #1761.
1643 * job.c (construct_command_argv_internal): Sanitize handling of
1644 backslash/newline pairs according to POSIX: that is, keep the
1645 backslash-newline in the command script, but remove a following
1646 TAB character, if present. In the fast path, make sure that the
1647 behavior matches what the shell would do both inside and outside
1648 of quotes. In the slow path, quote the backslash and put a
1649 literal newline in the string.
1650 Fixes Savannah bug #1332.
1651 * doc/make.texi (Execution): Document the new behavior and give
1653 * NEWS: Make a note of the new behavior.
1655 * make.h [WINDOWS32]: #include <direct.h>.
1656 Fixes Savannah bug #13478.
1658 * remake.c (name_mtime): If the stat() of a file fails and the -L
1659 option was given and the file is a symlink, take the best mtime of
1660 the symlink we can get as the mtime of the file and don't fail.
1661 Fixes Savannah bug #13280.
1663 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1664 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1665 inside a variable reference. Make this function static as it's
1667 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1668 parsing an unexpanded line looking for semicolons.
1669 Fixes Savannah bug #1454.
1670 * misc.c (remove_comments): Move this to read.c and make it static
1671 as it's only used there. Call find_char_unquote() with new arg.
1672 * make.h: Remove prototypes for find_char_unquote() and
1673 remove_comments() since they're static now.
1675 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1676 its export flag and obtain its value. When we need to re-exec,
1677 increment the value and add it into the environment.
1678 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1679 * NEWS: Mention MAKE_RESTARTS.
1680 * main.c (always_make_set): New variable. Change the -B option to
1681 set this one instead.
1682 (main): When checking makefiles, only set always_make_flag if
1683 always_make_set is set AND the restarts flag is 0. When building
1684 normal targets, set it IFF always_make_set is set.
1685 (main): Avoid infinite recursion with -W, too: only set what-if
1686 files to NEW before we check makefiles if we've never restarted
1687 before. If we have restarted, set what-if files to NEW _after_ we
1689 Fixes Savannah bug #7566:
1691 2005-06-17 Paul D. Smith <psmith@gnu.org>
1693 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1694 in the prerequisites list.
1696 2005-06-12 Paul D. Smith <psmith@gnu.org>
1698 Fix Savannah bug # 1328.
1700 * configure.in: Check for atexit().
1701 * misc.c (close_stdout): Test stdout to see if writes to it have
1702 failed. If so, be sure to exit with a non-0 error code. Based on
1703 code found in gnulib.
1704 * make.h: Prototype.
1705 * main.c (main): Install close_stdout() with atexit().
1707 2005-06-10 Paul D. Smith <psmith@gnu.org>
1709 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1711 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1712 headers; make vmsWaitForChildren() static; extern vmsify().
1713 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1714 Don't create child_execute_job() here (it's in vmsjobs.c).
1715 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1717 2005-06-09 Paul D. Smith <psmith@gnu.org>
1719 * variable.c (push_new_variable_scope): File variables point
1720 directly to the global_setlist variable. So, inserting a new
1721 scope in front of that has no effect on those variables: they
1722 don't go through current_variable_set_list. If we're pushing a
1723 scope and the current scope is global, push it "the other way" so
1724 that the new setlist is in the global_setlist variable, and
1725 next points to a new setlist with the global variable set.
1726 (pop_variable_scope): Properly undo a push with the new
1728 Fixes Savannah bug #11913.
1730 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1732 * job.c (reap_children): Don't die of the command failed but
1733 the dontcare flag is set. Fixes Savannah bug #13216.
1735 * implicit.c (pattern_search): When creating a target from
1736 an implicit rule match, lookup pattern target and set precious
1737 flag in a newly created target. Fixes Savannah bug #13218.
1739 2005-05-13 Paul D. Smith <psmith@gnu.org>
1741 Implement "if... else if... endif" syntax.
1743 * read.c (eval): Push all checks for conditional words ("ifeq",
1744 "else", etc.) down into the conditional_line() function.
1745 (conditional_line): Rework to allow "else if..." clause. New
1746 return value -2 for lines which are not conditionals. The
1747 ignoring flag can now also be 2, which means "already parsed a
1748 true branch". If that value is seen no other branch of this
1749 conditional can be considered true. In the else parsing if there
1750 is extra text after the else, invoke conditional_line()
1751 recursively to see if it's another conditional. If not, it's an
1752 error. If so, raise the conditional value to this level instead
1753 of creating a new conditional nesting level. Special check for
1754 "else" and "endif", which aren't allowed on the "else" line.
1755 * doc/make.texi (Conditional Syntax): Document the new syntax.
1757 2005-05-09 Paul D. Smith <psmith@gnu.org>
1759 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1760 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1761 recurses to the w32 directory, even on non-Windows systems. Use
1762 the method suggested in the automake manual.
1763 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1764 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1766 2005-05-07 Paul D. Smith <psmith@gnu.org>
1768 * main.c (die): If we're dying with a fatal error (not that a
1769 command has failed), write back any leftover tokens before we go.
1771 * job.c (set_child_handler_action_flags): If there are jobs
1772 waiting for the load to go down, set an alarm to go off in 1
1773 second. This allows us to wake up from a potentially long-lasting
1774 read() and start a new job if the load has gone down. Turn it off
1776 (job_noop): Dummy signal handler function.
1777 (new_job): Invoke it with the new semantics.
1779 * docs/make.texi: Document secondary expansion. Various cleanups
1782 2005-05-03 Paul D. Smith <psmith@gnu.org>
1784 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1785 the targets which are to ultimately be made are called "goals";
1786 see the GNU make manual. Also, MAKECMDGOALS, etc.
1788 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1789 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1790 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1792 2005-05-02 Paul D. Smith <psmith@gnu.org>
1794 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1795 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1796 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1797 functions to vmsjobs.c. #include it into jobs.c.
1799 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1800 jobserver tokens. I found that this happens when an exported
1801 recursive variable contains a $(shell ...) function reference: in
1802 this situation we could "forget" to write back a token.
1804 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1805 we have. It's not reliable to depend on the number of children in
1806 our linked list so keep a separate count.
1807 (new_job): Check jobserver_tokens rather than children &&
1808 waiting_jobs. Increment jobserver_tokens when we get one.
1809 (free_child): If jobserver_tokens is 0, internal error. If it's
1810 >1, write a token back to the jobserver pipe (we don't write a
1811 token for the "free" job). Decrement jobserver_tokens.
1813 * main.c: Add variable master_job_slots.
1814 (main): Set it to hold the number of jobs requested if we're the
1815 master process, when using the jobserver.
1816 (die): Sanity checks: first test jobserver_tokens to make sure
1817 this process isn't holding any tokens we didn't write back.
1818 Second, if master_job_slots is set count the tokens left in the
1819 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1821 2005-04-24 Paul D. Smith <psmith@gnu.org>
1823 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1824 with -l# can lose jobserver tokens, because waiting jobs are not
1825 consulted properly when checking for the "free" token.
1827 * job.c (free_child): Count waiting_jobs as having tokens.
1828 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1829 handle jobs waiting for the load to drop.
1831 2005-04-23 Paul D. Smith <psmith@gnu.org>
1833 * main.c (main): Be careful to not core if a variable setting in
1834 the environment doesn't contain an '='. This is illegal but can
1835 happen in broken setups.
1836 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1838 2005-04-12 Paul D. Smith <psmith@gnu.org>
1840 The second expansion feature causes significant slowdown. Timing
1841 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1842 read the makefile before the feature, to 11+s to do the same
1843 operations after the feature. Additionally, memory usage
1844 increased drastically. To fix this I added some intelligence that
1845 avoids the overhead of the second expansion unless it's required.
1847 * dep.h: Add a new boolean field, need_2nd_expansion.
1849 * read.c (eval): When creating the struct dep for the target,
1850 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1851 (record_files): If there's a "%" in a static pattern rule, it gets
1852 converted to "$*" so set need_2nd_expansion to 1.
1854 * file.c (expand_deps): Rework to be more efficient. Only perform
1855 initialize_file_variables(), set_file_variables(), and
1856 variable_expand_for_file() if the need_2nd_expansion is set.
1858 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1859 (pattern_search): Ditto.
1860 * main.c (handle_non_switch_argument): Ditto.
1862 * read.c (read_all_makefiles): Ditto.
1863 (eval_makefile): Ditto.
1865 2005-04-07 Paul D. Smith <psmith@gnu.org>
1867 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1868 * variable.c (sync_Path_environment): Ditto.
1869 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1871 * main.c (main): Define the .FEATURES variable.
1872 * NEWS: Announce .FEATURES.
1873 * doc/make.texi (Special Variables): Document .FEATURES.
1875 * remake.c (check_dep): If a file is .PHONY, update it even if
1876 it's marked intermediate. Fixes Savannah bug #12331.
1878 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1880 * file.c (expand_deps): Factor out the second expansion and
1881 prerequisite line parsing logic from snap_deps().
1883 * file.c (snap_deps): Use expand_deps(). Expand and parse
1884 prerequisites of the .SUFFIXES special target first. Fixes
1885 Savannah bug #12320.
1887 2005-03-13 Paul D. Smith <psmith@gnu.org>
1889 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1892 2005-03-11 Paul D. Smith <psmith@gnu.org>
1894 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1895 available, not undefined (from Earnie Boyd).
1897 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1899 * implicit.c (pattern_search): Mark an intermediate target as
1900 precious if it happened to be a prerequisite of some (other)
1901 target. Fixes Savannah bug #12267.
1903 2005-03-09 Paul D. Smith <psmith@gnu.org>
1905 * read.c (eval_makefile): Add alloca(0).
1906 (eval_buffer): Ditto.
1908 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1910 * main.c (main): Use o_file instead of o_default when defining
1911 the .DEFAULT_TARGET special variable.
1912 * read.c (eval): Use define_variable_global() instead of
1913 define_variable() when setting new value for the .DEFAULT_TARGET
1914 special variable. Fixes Savannah bug #12266.
1916 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1918 * imlicit.c (pattern_search): Mark files for which an implicit
1919 rule has been found as targets. Fixes Savannah bug #12202.
1921 2005-03-04 Paul D. Smith <psmith@gnu.org>
1924 * doc/make.texi (Automatic Variables): Document $|.
1926 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1928 * read.c (record_files): Instead of substituting % with
1929 actual stem value in dependency list replace it with $*.
1930 This fixes stem triple expansion bug.
1932 * implicit.c (pattern_search): Copy stem to a separate
1933 buffer and make it a properly terminated string. Assign
1934 this buffer instead of STEM (which is not terminated) to
1935 f->stem. Instead of substituting % with actual stem value
1936 in dependency list replace it with $*. This fixes stem
1937 triple expansion bug.
1939 2005-03-01 Paul D. Smith <psmith@gnu.org>
1941 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1942 on Windows, as it takes a handle not a pid. Just exit.
1943 Fix from patch #3679, provided by Alessandro Vesely.
1945 * configure.in: Update check for sys_siglist[] from autoconf manual.
1946 * signame.c (strsignal): Update to use the new autoconf macro.
1948 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1950 * read.c (record_files): Add a check for the list of prerequisites
1951 of a static pattern rule being empty. Fixes Savannah bug #12180.
1953 2005-02-28 Paul D. Smith <psmith@gnu.org>
1955 * doc/make.texi (Text Functions): Update docs to allow the end
1956 ordinal for $(wordlist ...) to be 0.
1957 * function.c (func_wordlist): Fail if the start ordinal for
1958 $(wordlist ...) is <1. Matches documentation.
1959 Resolves Savannah support request #103195.
1961 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1962 previously we were stopping when !-q, exactly the opposite. This
1963 has been wrong since version 1.34, in 1994!
1964 (update_file): If we got an error don't break out to run more
1965 double-colon rules: just return immediately.
1966 Fixes Savannah bug #7144.
1968 2005-02-27 Paul D. Smith <psmith@gnu.org>
1970 * misc.c (end_of_token): Make argument const.
1971 * make.h: Update prototype.
1973 * function.c (abspath, func_realpath, func_abspath): Use
1974 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1975 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1976 * read.c (record_files): Ditto.
1977 * variable.c (do_variable_definition): Ditto.
1979 * function.c (func_error): Create a new function $(info ...) that
1980 simply prints the message to stdout with no extras.
1981 (function_table_init): Add new function to the table.
1982 * NEWS: Add $(info ...) reference.
1983 * doc/make.texi (Make Control Functions): Document it.
1985 New feature: if the system supports symbolic links, and the user
1986 provides the -L/--check-symlink-time flag, then use the latest
1987 mtime between the symlink(s) and the target file.
1989 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1990 readlink(). If both are available, define MAKE_SYMLINKS.
1991 * main.c: New variable: check_symlink_flag.
1992 (usage): Add a line for -L/--check-symlink-times to the help string.
1993 (switches): Add -L/--check-symlink-times command line argument.
1994 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1995 print a warning and disable it again.
1996 * make.h: Declare check_symlink_flag.
1997 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1998 if the file is a symlink then check each link in the chain and
1999 choose the NEWEST mtime we find as the mtime for the file. The
2000 newest mtime might be the file itself!
2001 * NEWS: Add information about this new feature.
2002 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2004 Avoid core dumps described in Savannah bug # 12124:
2006 * file.c: New variable snapped_deps remember whether we've run
2008 (snap_deps): Set it.
2009 * filedef.h: Extern it.
2010 * read.c (record_files): Check snapped_deps; if it's set then
2011 we're trying to eval a new target/prerequisite relationship from
2012 within a command script, which we don't support. Fatal.
2014 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2016 Implementation of the .DEFAULT_TARGET special variable.
2018 * read.c (eval): If necessary, update default_target_name when
2020 * read.c (record_files): Update default_target_file if
2021 default_target_name has changed.
2022 * main.c (default_target_name): Define.
2023 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2024 default_target_name is set use default_target_file as a root
2026 * filedef.h (default_target_name): Declare.
2027 * dep.h (free_dep_chain):
2028 * misc.c (free_dep_chain): Change to operate on struct nameseq
2029 and change name to free_ns_chain.
2030 * file.c (snap_deps): Update to use free_ns_chain.
2032 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2034 Implementation of the second expansion in explicit rules,
2035 static pattern rules and implicit rules.
2037 * read.c (eval): Refrain from chopping up rule's dependencies.
2038 Store them in a struct dep as a single dependency line. Remove
2039 the code that implements SySV-style automatic variables.
2041 * read.c (record_files): Adjust the code that handles static
2042 pattern rules to expand all percents instead of only the first
2043 one. Reverse the order in which dependencies are stored so that
2044 when the second expansion reverses them again they appear in
2045 the makefile order (with some exceptions, see comments in
2046 the code). Remove the code that implements SySV-style automatic
2049 * file.c (snap_deps): Implement the second expansion and chopping
2050 of dependency lines for explicit rules.
2052 * implicit.c (struct idep): Define an auxiliary data type to hold
2053 implicit rule's dependencies after stem substitution and
2056 * implicit.c (free_idep_chain): Implement.
2058 * implicit.c (get_next_word): Implement helper function for
2059 parsing implicit rule's dependency lines into words taking
2060 into account variable expansion requests. Used in the stem
2063 * implicit.c (pattern_search): Implement the second expansion
2064 for implicit rules. Also fixes bug #12091.
2066 * commands.h (set_file_variables): Declare.
2067 * commands.c (set_file_variables): Remove static specifier.
2069 * dep.h (free_dep_chain): Declare.
2070 * misc.c (free_dep_chain): Implement.
2072 * variable.h (variable_expand_for_file): Declare.
2073 * expand.c (variable_expand_for_file): Remove static specifier.
2075 * make.h (strip_whitespace): Declare.
2076 * function.c (strip_whitespace): Remove static specifier.
2078 2005-02-26 Paul D. Smith <psmith@gnu.org>
2080 * main.c (main): Check for ferror() when reading makefiles from stdin.
2081 Apparently some shells in Windows don't close pipes properly and
2084 2005-02-24 Jonathan Grant <jg@jguk.org>
2086 * configure.in: Add MinGW configuration options, and extra w32 code
2088 * Makefile.am: Add MinGW configuration options, and extra w32 code
2090 * main.c: Determine correct program string (after last \ without .exe).
2091 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2093 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2094 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2095 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2096 environment support.
2098 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2100 * function.c (func_shell): When initializing error_prefix, check
2101 that reading file name is not null. This fixes long-standing
2102 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2104 2005-02-09 Paul D. Smith <psmith@gnu.org>
2106 * maintMakefile: Update the CVS download URL to simplify them.
2107 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2108 downloading the .texi files from Savannah now.
2110 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2112 * main.c (handle_non_switch_argument): Only add variables to
2113 command_variables if they're not already there: duplicate settings
2114 waste space and can be confusing to read.
2116 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2117 this header is never included by non-WINDOWS32 code, and it
2118 requires <config.h> to define which isn't always included first.
2120 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2121 testing MINGW32 versions.
2123 * main.c (log_working_directory): flush stdout to be sure the WD
2124 change is printed before any stderr messages show up.
2126 2005-02-01 Paul D. Smith <psmith@gnu.org>
2128 * maintMakefile (po_repo): Update the GNU translation site URL.
2130 2004-12-01 Paul D. Smith <psmith@gnu.org>
2132 * main.c (main): Change char* env_shell to struct variable shell_var.
2133 * variable.c (target_environment): Use new shell_var.
2135 2004-11-30 Paul D. Smith <psmith@gnu.org>
2137 * configure.in: The old way we avoided creating build.sh from
2138 build.sh.in before build.sh.in exists doesn't work anymore; we
2139 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2140 the help!). This also keeps automake from complaining.
2141 * Makefile.am (README): Add a dummy target so automake won't
2142 complain that this file doesn't exist when we checkout from CVS.
2143 * maintMakefile (.dep_segment): Rewrite this rule since newer
2144 versions of automake don't provide DEP_FILES.
2146 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2148 Implementation of `realpath' and `abspath' built-in functions.
2150 * configure.in: Check for realpath.
2151 * function.c (abspath): Return an absolute file name that does
2152 not contain any `.' or `..' components, nor repeated `/'.
2153 * function.c (func_abspath): For each name call abspath.
2154 * function.c (func_realpath): For each name call realpath
2155 from libc or delegate to abspath if realpath is not available.
2156 * doc/make.texi (Functions for File Names): Document new functions.
2157 * doc/make.texi (Quick Reference): Ditto.
2159 2004-11-28 Paul D. Smith <psmith@gnu.org>
2161 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2162 arguments. Fixes bug #10252.
2164 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2166 * main.c (main): Set SHELL to v_noexport by default. Remember the
2167 original environment setting of SHELL in the env_shell variable.
2168 * main.h: Export new env_shell variable.
2169 * variable.c (target_environment): If we find a v_noexport
2170 variable for SHELL, add a SHELL variable with the env_shell value.
2171 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2172 * doc/make.texi (Variables/Recursion): Ditto.
2174 2004-11-28 Paul D. Smith <psmith@gnu.org>
2176 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2177 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2178 Patch by Alessandro Vesely.
2180 2004-11-12 Paul D. Smith <psmith@gnu.org>
2182 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2183 the command line if it's inside a string.
2184 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2186 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2188 * function.c (func_lastword): New function: return last word
2189 from the list of words.
2190 * doc/make.texi: Document $(lastword ). Fix broken links in
2191 Quick Reference section.
2193 2004-10-06 Paul D. Smith <psmith@gnu.org>
2195 Apply patch from Alessandro Vesely, provided with bug # 9748.
2196 Fix use of tmpnam() to work with Borland C.
2198 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2199 construction of a temporary filename, and call new function
2200 create_batch_filename().
2201 (create_batch_filename) [WINDOWS32]: New function to create a
2204 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2206 * read.c (record_target_var): Expand simple pattern-specific
2208 * variable.c (initialize_file_variables): Do not expand simple
2209 pattern-specific variable.
2211 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2213 * remake.c (update_file_1): When rebuilding makefiles inherit
2214 dontcare flag from a target that triggered update.
2216 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2218 * variable.c (initialize_file_variables): Mark pattern-specific
2219 variable as a per-target and copy export status.
2221 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2223 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2225 * implicit.c (pattern_search): When considering an implicit rule's
2226 prerequisite check that it is actually a target rather then
2227 just an entry in the file hashtable.
2229 2004-09-21 Paul D. Smith <psmith@gnu.org>
2231 * read.c (readstring): Fix some logic errors in backslash handling.
2232 (eval): Remove some unnecessary processing in buffer handling.
2233 (record_target_var): Assert that parse_variable_definition() succeeded.
2234 Reported by: Markus Mauhart <qwe123@chello.at>.
2236 * misc.c: Removed the sindex() function. All instances of this
2237 function were trivially replaceable by the standard strstr()
2238 function, and that function will always have better (or certainly
2239 no worse) performance than the very simple-minded algorithm
2240 sindex() used. This can matter with complex makefiles.
2241 * make.h: Remove the prototype for sindex().
2242 * function.c (subst_expand): Convert sindex() call to strstr().
2243 This means we no longer need to track the TLEN value so remove that.
2244 (func_findstring): Convert sindex() to strstr().
2245 * commands.c (chop_commands): Convert sindex() calls to strstr().
2246 Suggested by: Markus Mauhart <qwe123@chello.at>.
2248 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2249 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2250 If SHELL is set to CMD.EXE then assume it's batch-mode and
2251 non-unixy. I wrote the code differently from the patch, though,
2252 to make it safer. This also resolves bug #9174.
2254 2004-09-20 Paul D. Smith <psmith@gnu.org>
2256 * expand.c (variable_expand_string): Modify to invoke
2257 patsubst_expand() instead of subst_expand(); the latter didn't
2258 handle suffix patterns correctly.
2259 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2260 was used only from variable_expand_string() and is no longer used
2262 (func_subst): Ditto, on call to subst_expand().
2263 (patsubst_expand): Require the percent pointers to point to the
2264 character after the %, not to the % itself.
2265 * read.c (record_files): New call criteria for patsubst_expand().
2266 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2267 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2269 2004-09-19 Paul D. Smith <psmith@gnu.org>
2271 * function.c (subst_expand): Fix a check in by_word: look for a
2272 previous blank if we're beyond the beginning of the string, not
2273 the beginning of the word.
2274 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2276 2004-05-16 Paul D. Smith <psmith@gnu.org>
2278 * remake.c (update_goal_chain): Change the argument specifying
2279 whether we're rebuilding makefiles to be a global variable,
2280 REBUILDING_MAKEFILES.
2281 (complain): Extract the code that complains about no rules to make
2282 a target into a separate function.
2283 (update_file_1): If we tried to rebuild a file during the makefile
2284 rebuild phase and it was dontcare, then no message was printed.
2285 If we then try to build the same file during the normal build,
2286 print a message this time.
2287 (remake_file): Don't complain about un-remake-able files when
2288 we're rebuilding makefiles.
2290 2004-05-11 Paul D. Smith <psmith@gnu.org>
2292 * job.c (construct_command_argv_internal): OS/2 patches from
2293 Andreas Buening <andreas.buening@nexgo.de>.
2295 2004-05-10 Paul D. Smith <psmith@gnu.org>
2297 * remake.c (update_file): Don't walk the double-colon chain unless
2298 this is a double-colon rule. Fix suggested by Boris Kolpackov
2299 <boris@kolpackov.net>.
2301 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2302 * readme.vms: New section describing OpenVMS support and issues.
2303 * default.c (default_variables): Add support for IA64.
2304 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2305 without some privilege aborts make with the error
2306 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2307 pressing Ctrl+Y and the input device is no terminal. The change
2308 catches this error and just continues.
2310 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2312 2004-04-25 Paul D. Smith <psmith@gnu.org>
2314 * commands.c (set_file_variables): Set $< properly in the face of
2315 order-only prerequisites.
2316 Patch from Boris Kolpackov <boris@kolpackov.net>
2318 2004-04-21 Bob Byrnes <byrnes@curl.com>
2320 * main.c (main): Notice failures to remake makefiles.
2322 2004-03-28 Paul D. Smith <psmith@gnu.org>
2324 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
2326 * job.c: No default shell for RISC OS.
2327 (load_too_high): Hard-code the return to 1.
2328 (construct_command_argv_internal): No sh_chars or sh_cmds.
2329 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2331 2004-03-20 Paul D. Smith <psmith@gnu.org>
2333 * variable.c (do_variable_definition): Don't append from the
2334 global set if a previous non-appending target-specific variable
2335 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2338 * expand.c (reference_variable): Don't give up on variables with
2339 no value that have the target-specific append flag set: they might
2340 have a value after all. Reported by Oliver Schmidt
2341 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2342 <nikulin@dx1cmd.inp.nsk.su>.
2344 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2345 refer to absolute pathnames in directories that don't exist: some
2346 portion of the makefile could create those directories before we
2347 match the pattern. Fixes bugs #775 and #108.
2349 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2351 * main.c (main): Free makefile_mtimes if we have any.
2352 * README.W32.template: Update documentation for the current status
2353 of the MS-Windows port.
2354 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2355 environment variable is sometimes already defined which causes the
2357 * main.c (debug_signal_handler): Only define this function if
2358 SIGUSR1 is available.
2360 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2362 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2363 * README.OS2.template: Documentation updates.
2364 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2365 link line for safety.
2366 * maintMakefile (build.sh.in): Remove an extraneous ")".
2367 * job.c (child_execute_job): Close saved FDs.
2368 * job.c (exec_command) [OS/2]: exec_command(): If the command
2369 can't be exec'ed and if the shell is not Unix-sh, then try again
2370 with argv = { "cmd", "/c", ... }. Normally, this code is never
2371 reached for the cmd shell unless the command really doesn't exist.
2372 (construct_command_argv_internal) [OS/2]: The code for cmd
2373 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2374 The CMD builtin commands are case insensitive so use strcasecmp().
2376 2004-03-19 Paul D. Smith <psmith@gnu.org>
2378 * read.c (do_define): Re-order line counter increment so the count
2379 is accurate (we were losing one line per define). Reported by
2380 Dave Yost <Dave@Yost.com>.
2382 2004-03-06 Paul D. Smith <psmith@gnu.org>
2384 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2386 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2387 * misc.c (message,error,fatal): Ditto.
2388 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2389 * config.h.W32.template: Ditto.
2390 * config.h-vms.template: Ditto.
2391 * config.ami.template: Ditto.
2393 2004-03-04 Paul D. Smith <psmith@gnu.org>
2395 * README.template: Add a note about broken /bin/sh on SunOS
2396 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2398 * misc.c (message, error, fatal): Don't use "..." if we're using
2399 varargs. ansi2knr should handle this but it doesn't work: it
2400 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2401 done. On many systems (SunOS for example) va_dcl is a #define.
2402 So, force the use of the non-"..." version on pre-ANSI compilers.
2404 * maintMakefile (sign-dist): Create some rules to help automate
2405 the new GNU ftp upload method.
2407 2004-02-24 Paul D. Smith <psmith@gnu.org>
2409 * config.h.W32.template: Add HAVE_STDARG_H
2410 * config.h-vms.template: Ditto.
2411 * config.ami.template: Ditto.
2413 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2415 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2416 * build_w32.bat: Remove extra "+".
2418 2004-02-23 Paul D. Smith <psmith@gnu.org>
2420 * make.h: Create an UNUSED macro to mark unused parameters.
2421 * (many): Clean up warnings by applying UNUSED, fixing
2422 signed/unsigned incompatibilities, etc.
2424 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2426 * filedef.h: Name the command_state enumeration.
2427 * file.c (set_command_state): Use the enumeration in the function
2430 * configure.in: Explicitly set SET_MAKE to empty, to disable
2431 MAKE=make even when no make already exists. Fix bug #3823.
2433 2004-02-22 Paul D. Smith <psmith@gnu.org>
2435 * maintMakefile: Perl script to clean up all non-CVS files. Use
2436 it on all the subdirectories for the cvs-clean target.
2438 * main.c (decode_switches): Require non-empty strings for all our
2439 string command-line options. Fixes Debian bug # 164165.
2441 * configure.in: Check for stdarg.h and varargs.h.
2442 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2443 for printing messages.
2444 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2449 A number of patches for OS/2 support from Andreas Buening
2450 <andreas.buening@nexgo.de>:
2452 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2453 disable the SIGCHLD handler.
2454 (reap_children) [OS/2]: Remove special handling of job_rfd.
2455 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2456 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2457 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2458 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2459 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2462 2004-02-21 Paul D. Smith <psmith@gnu.org>
2464 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2465 <mail@kristov.de> reports that if process_begin() fails we don't
2466 handle the error condition correctly in all cases.
2467 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2468 to have a newline on the message.
2470 * job.c (construct_command_argv_internal): Add "test" to UNIX
2471 sh_cmds[]. Fixes Savannah bug # 7606.
2473 2004-02-04 Paul D. Smith <psmith@gnu.org>
2475 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2476 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2477 Hartmut Becker <Hartmut.Becker@hp.com>.
2479 2004-01-21 Paul D. Smith <psmith@gnu.org>
2481 * job.c (load_too_high): Implement an algorithm to control the
2482 "thundering herd" problem when using -l to control job creation
2483 via the load average. The system only recomputes the load once a
2484 second but we can start many jobs in a second. To solve this we
2485 keep track of the number of jobs started in the last second and
2486 apply a weight to try to guess what a correct load would be.
2487 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2488 Also fixes bug #4693.
2489 (reap_children): Decrease the job count for this second.
2490 (start_job_command): Increase the job count for this second.
2492 * read.c (conditional_line): Expand the text after ifn?def before
2493 checking to see if it's a single word. Fixes bug #7257.
2495 2004-01-09 Paul D. Smith <psmith@gnu.org>
2497 * file.c (print_file): Recurse to print all targets in
2498 double-colon rules. Fixes bug #4518, reported (with patch) by
2499 Andrew Chatham <chatham@google.com>.
2501 2004-01-07 Paul D. Smith <psmith@gnu.org>
2503 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2504 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2505 AC_FUNC_SETVBUF_REVERSED.
2507 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2508 (MAKE Variable): Fix Savannah bug #4898.
2510 * job.c (construct_command_argv_internal): Add "!" to the list of
2511 shell escape chars. POSIX sh allows it to appear before a
2512 command, to negate the exit code. Fixes bug #6404.
2514 * implicit.c (pattern_search): When matching an implicit rule,
2515 remember which dependencies have the ignore_mtime flag set.
2516 Original fix provided in Savannah patch #2349, by Benoit
2517 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2519 2003-11-22 Paul D. Smith <psmith@gnu.org>
2521 * README.W32.template (Outputs): Clarification on -j with
2522 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2525 2003-11-02 Paul D. Smith <psmith@gnu.org>
2527 * function.c (func_if): Strip all the trailing whitespace from the
2528 condition, then don't expand it. Fixed bug # 5798.
2530 * expand.c (recursively_expand_for_file): If we're expanding a
2531 variable with no file context, then use the variable's context.
2534 2003-10-21 Paul D. Smith <psmith@gnu.org>
2536 * main.c (log_working_directory): Add newlines to printf()s.
2538 * README.cvs: Add a note to ignore warnings during autoreconf.
2540 * maintMakefile (po_repo): Set a new URL for PO file updates.
2541 (get-config/config.guess get-config/config.sub): Get these files
2542 from the Savannah config project instead of ftp.gnu.org.
2544 2003-10-05 Paul Eggert <eggert@twinsun.com>
2546 * main.c (main): Avoid potential subscript error if environ has
2549 2003-08-22 Paul D. Smith <psmith@gnu.org>
2551 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2552 systems which don't yet implement the C89 standard :-/.
2554 2003-07-18 Paul D. Smith <psmith@gnu.org>
2556 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2557 [WINDOWS32]: Initialize hash.
2559 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2561 * dir.c (read_dirstream): Provide a workaround for broken versions of
2562 the MinGW dirent structure.
2564 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2566 * w32/include/dirent.h: Add __MINGW32__ filter.
2568 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2570 * make.h: Add global declaration of *make_host.
2571 * main.c (print_usage): Remove local declaration of *make_host.
2572 (print_version): Display "This program built for ..." after Copyright
2575 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2577 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2578 execution of "makeinfo --html make.texi".
2580 2003-04-30 Paul D. Smith <psmith@gnu.org>
2582 * build.template: Make some changes to maybe allow this script to
2583 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2585 * README.OS2.template: New file for OS/2 support. Original
2586 contributed by Andreas Buening.
2587 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2590 2003-04-19 Paul D. Smith <psmith@gnu.org>
2592 Fix bug #1405: allow a target to match multiple pattern-specific
2595 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2596 variable.c, where they've always belonged.
2597 * rule.h: Move the prototypes and struct pattern_var as well.
2598 * variable.c (initialize_file_variables): Invoke
2599 lookup_pattern_var() in a loop, until no more matches are found.
2600 If a match is found, create a new variable set for the target's
2601 pattern variables. Then merge the contents of each matching
2602 pattern variable set into the target's pattern variable set.
2603 (lookup_pattern_var): Change this function to be usable
2604 in a loop. It takes a starting position: if NULL, start at the
2605 beginning; if non-NULL, start with the pattern variable after that
2606 position, and return the next matching pattern.
2607 (create_pattern_var): Create a unique instance of
2608 pattern-specific variables for every definition in the makefile.
2609 Don't combine the same pattern together. This allows us to
2610 process the variable handling properly even when the same pattern
2611 is used multiple times.
2612 (parse_variable_definition): New function: break out the parsing
2613 of a variable definition line from try_variable_definition.
2614 (try_variable_definition): Call parse_variable_definition to
2616 (print_variable_data_base): Print out pattern-specific variables.
2617 * variable.h (struct variable): Remember when a variable is
2618 conditional. Also remember its flavor.
2619 (struct pattern_var): Instead of keeping a variable set, we just
2620 keep a single variable for each pattern.
2621 * read.c (record_target_var): Each pattern variable contains only a
2622 single variable, not a set, so create it properly.
2623 * doc/make.texi (Pattern-specific): Document the new behavior.
2625 2003-04-17 Paul D. Smith <psmith@gnu.org>
2627 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2628 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2629 file/directory naming rules for VMS so I can't tell whether this
2632 2003-04-09 Paul D. Smith <psmith@gnu.org>
2634 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2635 DOS-style pathnames: backslash separators and drive specifiers.
2637 2003-03-28 Paul D. Smith <psmith@gnu.org>
2639 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2640 the intermediate flag on all targets. Fixes bug #2515.
2642 2003-03-24 Paul D. Smith <psmith@gnu.org>
2644 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2645 Upgrade to autoconf 2.57 and automake 1.7.3.
2647 * job.c: More OS/2 changes from Andreas Buening.
2649 * file.c (print_file): Fix variable initialization.
2652 * remake.c (notice_finished_file):
2654 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2655 some calls (like readdir()) return NULL in valid situations
2656 without resetting errno. Fixes bug #2846.
2658 2003-02-25 Paul D. Smith <psmith@gnu.org>
2660 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2662 * job.c (_is_unixy_shell) [OS/2]: New function.
2663 Set default shell to /bin/sh.
2664 (reap_children): Close the job_rfd pipe here since we don't use a
2666 (set_child_handler_action_flags): define this to empty on OS/2.
2667 (start_job_command): Close the jobserver pipe and use
2668 child_execute_job() instead of fork/exec.
2669 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2670 rather than exec'ing, then reconfigure stdin/stdout.
2671 (exec_command): Rewrite to use spawn instead of exec. Return the
2674 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2675 in DOS. Handle the TEMP environment variable as in DOS. Don't
2676 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2677 use -j in DOS mode. Use child_execute_job() instead of
2680 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2683 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2684 prototypes that return values.
2686 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2688 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2689 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2691 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2694 2003-02-24 Paul D. Smith <psmith@gnu.org>
2696 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2697 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2698 (child_execute_job) [VMS]: Handle error status properly.
2699 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2701 * function.c (func_shell): Use EINTRLOOP() while reading from the
2702 subshell pipe (Fixes bug #2502).
2703 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2705 * main.c (main): Ditto.
2707 2003-01-30 Paul D. Smith <psmith@gnu.org>
2709 * read.c (eval): eval() was not fully reentrant, because the
2710 collapsed buffer was static. Change it to be an automatic
2711 variable so that eval() can be invoked recursively.
2713 (eval): Apply patch # 1022: fix memory reference error on long
2714 target-specific variable lines.
2715 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2717 * function.c (check_numeric): Combine the is_numeric() function
2718 into this function, since it's only called from one place.
2719 Constify this function. Have it print the incorrect string in the
2720 error message. Fixes bug #2407.
2721 (strip_whitespace): Constify.
2722 (func_if): Constify.
2723 * expand.c (expand_argument): Constify.
2725 2003-01-29 Paul D. Smith <psmith@gnu.org>
2727 Fix bug # 2169, also reported by other people on various systems.
2729 * make.h: Some systems, such as Solaris and PTX, do not fully
2730 implement POSIX-compliant SA_RESTART functionality; important
2731 system calls like stat() and readdir() can still fail with EINTR
2732 even if SA_RESTART has been set on the signal handler. So,
2733 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2734 EINTR for system calls which return -1 or 0 (NULL), respectively,
2736 Also, remove the old atomic_stat()/atomic_readdir() and
2737 HAVE_BROKEN_RESTART handling.
2739 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2741 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2742 * remake.c (touch_file): Ditto.
2744 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2745 * read.c (construct_include_path): Ditto.
2746 * remake.c (name_mtime): Ditto.
2747 * vpath.c (selective_vpath_search): Ditto.
2748 * dir.c (find_directory): Ditto.
2749 (local_stat): Ditto.
2750 (find_directory): Use ENULLLOOP() to wrap opendir().
2751 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2753 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2754 atomic_readdir() handling.
2756 2003-01-22 Paul D. Smith <psmith@gnu.org>
2758 * function.c (func_call): Fix Bug #1744. If we're inside a
2759 recursive invocation of $(call ...), mask any of the outer
2760 invocation's arguments that aren't used by this one, so that this
2761 invocation doesn't "inherit" them accidentally.
2763 2002-12-05 Paul D. Smith <psmith@gnu.org>
2765 * function.c (subst_expand): Valery Khamenia reported a
2766 pathological performance hit when doing substitutions on very
2767 large values with lots of words: turns out we were invoking
2768 strlen() a ridiculous number of times. Instead of having each
2769 call to sindex() call strlen() again, keep track of how much of
2770 the text we've seen and pass the length to sindex().
2772 2002-11-19 Paul D. Smith <psmith@gnu.org>
2774 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2777 2002-11-16 Paul D. Smith <psmith@gnu.org>
2779 * NMakefile.template (OBJS): Add hash.c object file.
2780 * SMakefile.template (srcs): Ditto.
2781 * Makefile.ami (objs): Ditto.
2782 * build_w32.bat: Ditto.
2784 * Makefile.DOS.template: Remove extra dependencies.
2786 2002-10-25 Paul D. Smith <psmith@gnu.org>
2788 * expand.c (install_variable_buffer): New function. Install a new
2789 variable_buffer context and return the previous one.
2790 (restore_variable_buffer): New function. Free the current
2791 variable_buffer context and put a previously saved one back.
2792 * variable.h: Prototypes for {install,restore}_variable_buffer.
2793 * function.c (func_eval): Push a new variable_buffer context
2794 before we eval, then restore the old one when we're done.
2797 * read.c (install_conditionals): New function. Install a new
2798 conditional context and return the previous one.
2799 (restore_conditionals): New function. Free the current
2800 conditional context and put a previously saved one back.
2801 (eval): Use the {install,restore}_conditionals for "include"
2803 (eval_buffer): Use {install,restore}_conditionals to preserve the
2804 present conditional state before we evaluate the buffer.
2807 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2809 (Recursion): Add a variable index entry for CURDIR.
2811 * README.cvs: Update to appropriate versions.
2812 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2813 don't need to copy loadavg.c: automake is smart enough to create
2814 it for me. Still have a bug in automake related to ansi2knr tho.
2816 2002-10-14 Paul D. Smith <psmith@gnu.org>
2818 * remake.c (notice_finished_file): Only touch targets if they have
2819 at least one command (as per POSIX). Resolve Bug #1418.
2821 * *.c: Convert to using ANSI C-style function definitions.
2822 * Makefile.am: Enable the ansi2knr feature of automake.
2823 * configure.in: ditto.
2825 2002-10-13 Paul D. Smith <psmith@gnu.org>
2827 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2828 for automatic variable values like $^, etc. In the case of very
2829 large lists of prerequisites this causes problems. Instead reuse
2830 a static buffer (resizeable) for each variable.
2832 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2833 target-specific variable definitions. Check for it and set an
2835 (record_target_var): Set the export field to v_export if the
2836 "exported" flag is set.
2837 * doc/make.texi (Target-specific): Document the ability to use
2840 * doc/make.texi: Change the name of the section on automatic
2841 variables from "Automatic" to "Automatic Variables". Added text
2842 clarifying the scope of automatic variables.
2844 2002-10-04 Paul D. Smith <psmith@gnu.org>
2846 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2848 (record_files): Ditto.
2850 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2851 the search for the '=' to only within the enclosing parens.
2853 2002-10-03 Paul D. Smith <psmith@gnu.org>
2855 Version 3.80 released.
2857 * dir.c: Change hash functions to use K&R function definition style.
2858 * function.c: Ditto.
2860 * variable.c: Ditto.
2862 Update to automake 1.7.
2864 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2865 (pdf): Remove this target as automake now provides one.
2867 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2869 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2871 * makefile.com: Updates for GNU make 3.80.
2872 * makefile.vms: Ditto.
2874 2002-09-23 Paul D. Smith <psmith@gnu.org>
2876 * read.c (enum make_word_type): Remove w_comment.
2877 (get_next_mword): Don't treat comment characters as special; where
2878 this function is used we will never see a comment (it's stripped
2879 before we get here) and treating comments specially means that
2880 targets like "foo\#bar" aren't handled properly.
2882 2002-09-18 Paul D. Smith <psmith@gnu.org>
2884 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2886 * read.c (eval): Expansion of arguments to export/unexport was
2887 ignoring all arguments after the first one. Change the algorithm
2888 to expand the whole line once, then parse the results.
2890 2002-09-17 Paul D. Smith <psmith@gnu.org>
2892 Fix Bug #940 (plus another bug I found while looking at this):
2894 * read.c (record_target_var): enter_file() will add a new entry if
2895 it's a double-colon target: we don't want to do that in this
2896 situation. Invoke lookup_file() and only enter_file() if it does
2897 not already exist. If the file we get back is a double-colon then
2898 add this variable to the "root" double-colon target.
2900 * variable.c (initialize_file_variables): If this file is a
2901 double-colon target but is not the "root" target, then initialize
2902 the root and make the root's variable list the parent of our
2905 2002-09-13 Paul D. Smith <psmith@gnu.org>
2907 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2909 * hash.c (round_up_2): Get rid of a warning.
2911 2002-09-12 Paul D. Smith <psmith@gnu.org>
2913 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2914 so it doesn't complain about getloadavg.c.
2916 * commands.c (set_file_variables): Make sure we always alloca() at
2917 least 1 character for the value of $? (for '\0').
2919 2002-09-11 Paul D. Smith <psmith@gnu.org>
2921 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2922 macro to use RESULT instead of the incorrect _RESULT_.
2924 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2925 and atomic_readdir(). We need to #include dirent.h to get this to
2927 * misc.c (atomic_readdir): Fix typos.
2929 2002-09-10 Paul D. Smith <psmith@gnu.org>
2931 * read.c (eval): Expand variable lists given to export and
2932 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2933 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2935 * doc/make.texi (Variables/Recursion): Document this.
2936 (Conditional Syntax): And here.
2938 2002-09-09 Paul D. Smith <psmith@gnu.org>
2940 * configure.in: Check for memmove().
2942 2002-09-07 Paul D. Smith <psmith@gnu.org>
2944 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2945 Michael Sterrett <msterret@coat.com> reports that while it has
2946 SA_RESTART, it does not work properly.
2948 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2949 that invokes stat() and loops to do it again if it returns EINTR.
2950 (atomic_readdir): Ditto, with readdir().
2952 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2953 and readdir() to atomic_stat() and atomic_readdir().
2955 2002-09-04 Paul D. Smith <psmith@gnu.org>
2957 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2958 reports that GNU make sometimes doesn't recognize that targets can
2959 be made, when directories can be created as prerequisites. He
2960 reports that changing the order of predicates in the DEP->changed
2961 flag test so that lookup_file() is always performed, solves this
2964 2002-08-08 Paul D. Smith <psmith@gnu.org>
2966 * configure.in: Require a newer version of gettext.
2968 * misc.c (perror_with_name): Translate the format string (for
2969 right-to-left language support).
2970 (pfatal_with_name): Ditto.
2972 * main.c: Create a static array of strings to store the usage
2973 text. This is done to facilitate translations.
2974 (struct command_switch): Remove argdesc and description fields.
2975 (switches): Remove values for obsolete fields.
2976 (print_usage): Print each element of the usage array.
2978 * hash.c: Change function definitions to be K&R style.
2980 2002-08-02 Paul D. Smith <psmith@gnu.org>
2982 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2983 this one because it's too hard to get right. We'll look at it for
2985 * main.c (main): Don't create the .TARGETS variable.
2986 * variable.c (handle_special_var): Don't handle .TARGETS.
2988 2002-08-01 Paul D. Smith <psmith@gnu.org>
2990 * main.c (switches): Add a new option, -B (--always-make). If
2991 specified, make will rebuild all targets that it encounters even
2992 if they don't appear to be out of date.
2993 (always_make_flag): New flag.
2994 * make.h: Extern always_make_flag.
2995 * remake.c (update_file_1): Check always_make_flag; if it's set we
2996 will always rebuild any target we can, even if none of its
2997 prerequisites are newer.
3000 * doc/make.texi (Shell Function): Make it clear that make
3001 variables marked as "export" are not passed to instances of the
3004 Add new introspection variable .VARIABLES and .TARGETS.
3006 * variable.c (handle_special_var): New function. If the variable
3007 reference passed in is "special" (.VARIABLES or .TARGETS),
3008 calculate the new value if necessary. .VARIABLES is handled here:
3009 walk through the hash of defined variables and construct a value
3010 which is a list of the names. .TARGETS is handled by
3011 build_target_list().
3012 (lookup_variable): Invoke handle_special_var().
3013 * file.c (build_target_list): Walk through the hask of known files
3014 and construct a list of the names of all the ones marked as
3016 * main.c (main): Initialize them to empty (and as simple variables).
3017 * doc/make.texi (Special Variables): Document them.
3018 * NEWS: Mention them.
3020 * variable.h (struct variable): Add a new flag "exportable" which
3021 is true if the variable name is valid for export.
3022 * variable.c (define_variable_in_set): Set "exportable" when a new
3023 variable is defined.
3024 (target_environment): Use the "exportable" flag instead of
3025 re-checking the name here... an efficiency improvement.
3027 2002-07-31 Paul D. Smith <psmith@gnu.org>
3029 * config.h-vms.template: Updates to build on VMS. Thanks to
3030 Brian_Benning@aksteel.com for helping verify the build.
3031 * makefile.com: Build the new hash.c file.
3032 * hash.h: Use strcpmi(), not stricmp(), in the
3033 HAVE_CASE_INSENSITIVE_FS case.
3035 2002-07-30 Paul D. Smith <psmith@gnu.org>
3037 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3038 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3039 Reported by <Brian_Benning@aksteel.com>.
3041 2002-07-10 Paul D. Smith <psmith@gnu.org>
3043 * variable.c (pop_variable_scope): Remove variable made unused by
3044 new hash infrastructure.
3045 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3046 comparisons as well as name comparisons.

3048 * file.c (lookup_file): Remove variables made unused by new hash
3050 * dir.c (directory_contents_hash_2): Missing return of hash value.
3051 (dir_contents_file_exists_p): Remove variables made unused by new
3052 hash infrastructure.
3055 Installed Greg McGary's integration of the hash functions from the
3056 GNU id-utils package:
3058 2002-07-10 Greg McGary <greg@mcgary.org>
3060 * scripts/functions/filter-out: Add literals to to the
3061 pattern space in order to add complexity, and trigger
3062 use of an internal hash table. Fix documentation strings.
3063 * scripts/targets/INTERMEDIATE: Reverse order of files
3064 passed to expected `rm' command.
3066 2002-07-10 Greg McGary <greg@mcgary.org>
3068 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h

3125 (struct a_pattern): New struct.
3126 (func_filter_filterout): Pass through patterns noting boundaries
3127 and '%', if present. Note a_word length. Use a hash table if
3128 arglists are large enough to justify cost.
3129 (function_table_init): Renamed from function_table.
3130 (function_table): Declare as `struct hash_table'.
3131 (FUNCTION_TABLE_ENTRIES): New constant.
3132 (hash_init_function_table): New function.
3134 * read.c (hash.h): New #include.
3135 (read_makefile): Pass char constants to find_char_unquote.
3136 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions.
3137 (uniquize_deps): Use hash table to efficiently identify duplicates.
3138 (find_char_unquote): Accept two char-constant stop chars, rather
3139 than a string constant, avoiding zillions of calls to strchr.
3140 Tighten inner search loops to test only for desired delimiters.
3142 * variable.c (variable_hash_1, variable_hash_2,
3143 variable_hash_cmp): New functions.
3144 (variable_table): Declare as `struct hash_table'.
3145 (global_variable_set): Remove initialization.
3146 (init_hash_global_variable_set): New function.
3147 (define_variable_in_set): Use new hash table package.
3148 (lookup_variable): Likewise.
3149 (lookup_variable_in_set): Likewise.
3150 (initialize_file_variables): Likewise.
3151 (pop_variable_scope): Likewise.
3152 (create_new_variable_set): Likewise.
3153 (merge_variable_sets): Likewise.
3154 (define_automatic_variables): Likewise.
3155 (target_environment): Likewise.
3156 (print_variable_set): Likewise.
3158 2002-07-10 Paul D. Smith <psmith@gnu.org>
3160 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3161 prerequisite list. A real SysV make will expand the entire
3162 prerequisites list _twice_: we don't do that as it's a big
3163 backward-compatibility problem. We only replace those specific
3166 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3167 references left in the list of prerequisites. Check for .POSIX as
3168 we record targets, so we can disable non-POSIX behavior while
3169 reading makefiles as well as running them.
3170 (eval): Check the prerequisite list to see if we have anything
3171 that looks like a SysV prerequisite variable reference.
3173 2002-07-09 Paul D. Smith <psmith@gnu.org>
3175 * doc/make.texi (Prerequisite Types): Add a new section describing
3176 order-only prerequisites.
3178 * read.c (uniquize_deps): If we have the same file as both a
3179 normal and order-only prereq, get rid of the order-only prereq,
3180 since the normal one supersedes it.
3182 2002-07-08 Paul D. Smith <psmith@gnu.org>
3184 * AUTHORS: Added Greg McGary to the AUTHORS file.
3185 * NEWS: Blurbed order-only prerequisites.
3186 * file.c (print_file): Show order-only deps properly when printing
3189 * maintMakefile: Add "update" targets for wget'ing the latest
3190 versions of various external files. Taken from Makefile.maint in
3193 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3194 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3196 2002-07-07 Paul D. Smith <psmith@gnu.org>
3198 * po/*.po: Remove. We'll use wget to retrieve them at release
3201 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3202 rather than a shell you get an exception. Make sure we look up
3203 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3205 * remake.c (notice_finished_file): Fix handling of -t flag.
3206 Patch provided by Henning Makholm <henning@makholm.net>.
3208 * implicit.c (pattern_search): Some systems apparently run short
3209 of stack space, and using alloca() in this function caused an
3210 overrun. I modified it to use xmalloc() on the two variables
3211 which seemed like they might get large. Fixes Bug #476.
3213 * main.c (print_version): Update copyright notice to conform with
3215 (print_usage): Update help output.
3217 * function.c (func_eval): Create a new make function, $(eval
3218 ...). Expand the arguments, put them into a buffer, then invoke
3219 eval_buffer() on the resulting string.
3220 (func_quote): Create a new function, $(quote VARNAME). Inserts
3221 the value of the variable VARNAME without expanding it any
3224 * read.c (struct ebuffer): Change the linebuffer structure to an
3225 "eval buffer", which can be either a file or a buffer.
3226 (eval_makefile): Move the code in the old read_makefile() which
3227 located a makefile into here: create a struct ebuffer with that
3228 information. Have it invoke the new function eval() with that
3230 (eval_buffer): Create a new function that creates a struct ebuffer
3231 that holds a string buffer instead of a file. Have it invoke
3232 eval() with that ebuffer.
3233 (eval): New function that contains the guts of the old
3234 read_makefile() function: this function parses makefiles. Obtains
3235 data to parse from the provided ebuffer. Some modifications to
3236 make the flow of the function cleaner and clearer. Still could
3237 use some work here...
3238 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3239 contents of the define/endef variable from the ebuffer.
3240 (readstring): Read the next line from a string-style ebuffer.
3241 (readline): Read the next line from an ebuffer. If it's a string
3242 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3245 * dep.h (eval_buffer): Prototype eval_buffer();
3247 * variable.c (do_variable_definition): Make sure that all
3248 non-target-specific variables are registered in the global set.
3249 If we're invoked from an $(eval ...) we might be inside a $(call
3250 ...) or other function which has pushed a variable scope; we still
3251 want to define our variables from evaluated makefile code in the
3254 2002-07-03 Greg McGary <greg@mcgary.org>
3256 * dep.h (struct dep) [ignore_mtime]: New member.
3257 [changed]: convert to a bitfield.
3258 * implicit.c (pattern_search): Zero ignore_mtime.
3259 * main.c (main, handle_non_switch_argument): Likewise.
3260 * rule.c (convert_suffix_rule): Likewise.
3261 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3262 (read_makefile): Parse '|' in prerequisite list.
3263 (uniquize_deps): Consider ignore_mtime when comparing deps.
3264 * remake.c (update_file_1, check_dep): Don't force remake for
3265 dependencies that have d->ignore_mtime.
3266 * commands.c (FILE_LIST_SEPARATOR): New constant.
3267 (set_file_variables): Don't include a
3268 prerequisite in $+, $^ or $? if d->ignore_mtime.
3271 2002-06-18 Paul D. Smith <psmith@gnu.org>
3273 * make.texinfo: Updates for next revision. New date/rev/etc.
3274 Recreate all Info menus. Change license on the manual to the GNU
3275 Free Documentation License. A number of typos.
3276 (Variables Simplify): Don't use "-" before it's defined.
3277 (Automatic Prerequisites): Rewrite the target example to work
3278 properly if the compile fails. Remove incorrect comments about
3279 how "set -e" behaves.
3280 (Text Functions): Move the "word", "wordlist", "words", and
3281 "firstword" functions here, from "File Name Functions".
3282 * make-stds.texi: Update from latest GNU version.
3283 * fdl.texi: (created) Import the latest GNU version.
3285 2002-06-06 Paul D. Smith <psmith@gnu.org>
3287 * variable.c (do_variable_definition): New function: extract the
3288 part of try_variable_definition() that actually sets the value
3289 into a separate function.
3290 (try_variable_definition): Call do_variable_definition() after
3291 parsing the variable definition string.
3292 (define_variable_in_set): Make the name argument const.
3294 * variable.h (enum variable_flavor): Make public.
3295 (do_variable_definition): Create prototype.
3297 * read.c (read_all_makefiles): Create a new built-in variable,
3299 (read_makefile): Add each makefile read in to this variable value.
3301 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3303 * Makefile.DOS.template: Tweak according to changes in the
3304 distribution. Add back the dependencies of *.o files.
3306 * configh.dos.template: Synchronize with config.h.in.
3308 2002-05-09 Paul D. Smith <psmith@gnu.org>
3310 * file.c (file_timestamp_now): Use K&R function declaration.
3312 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3313 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
3314 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
3315 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
3316 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
3317 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
3318 nlist.n_name is a pointer rather than an array.
3320 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
3321 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
3322 * configure.in: Use it instead of the old version.
3324 * main.c (main): Prefer setvbuf() to setlinebuf().
3326 2002-05-08 Paul D. Smith <psmith@gnu.org>
3328 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
3329 (loadavg_LDADD): Ditto.
3331 2002-04-29 Paul D. Smith <psmith@gnu.org>
3333 * expand.c (recursively_expand_for_file): Rename
3334 recursively_expand() to recursively_expand_for_file() and provide
3335 an extra argument, struct file. If the argument is provided, set
3336 the variable scope to that of the file before expanding.
3337 * variable.h (recursively_expand): Make this a macro that invokes
3338 recursively_expand_for_file() with a NULL file pointer.
3339 * variable.c (target_environment): Call the renamed function and
3340 provide the current file context.
3341 Fixes Debian bug #144306.
3343 2002-04-28 Paul D. Smith <psmith@gnu.org>
3345 Allow $(call ...) user-defined variables to be self-referencing
3346 without throwing an error. Allows implementation of transitive
3347 closures, among other possibly useful things.
3348 Requested by: Philip Guenther <guenther@sendmail.com>
3350 * variable.h (struct variable): Add a new field: exp_count, and
3351 new macros to hold its size and maximum value.
3352 (warn_undefined): Make this a macro.
3353 * variable.c (define_variable_in_set): Initialize it.
3354 * expand.c (recursively_expand): If we detect recursive expansion
3355 of a variable, check the exp_count field. If it's greater than 0
3356 allow the recursion and decrement the count.
3357 (warn_undefined): Remove this (now a macro in variable.h).
3358 * function.c (func_call): Before we expand the user-defined
3359 function, modify its exp_count field to contain the maximum
3360 number of recursive calls we'll allow. After the call, reset it
3363 2002-04-21 Paul D. Smith <psmith@gnu.org>
3365 Modified to use latest autoconf (2.53), automake (1.6.1), and
3366 gettext (0.11.1). We're using gettext's new "external" support,
3367 to avoid including libintl source with GNU make.
3369 * README.cvs: New file. Explain how to build GNU make from CVS.
3371 * configure.in: Modify checking for the system glob library.
3372 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3373 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3374 etc. will manage it correctly). Set an automake conditional
3375 USE_LOCAL_GLOB to decide whether to compile the glob library.
3377 * getloadavg.c (main): Include make.h in the "TEST" program to
3380 * Makefile.am: Remove special rules for loadavg. Replace them
3381 with Automake capabilities for building extra programs.
3383 * signame.c: This file does nothing if the system provide
3384 strsignal(). If not, it implements strsignal(). If the system
3385 doesn't define sys_siglist, then we make our own; otherwise we use
3387 * signame.h: Removed.
3389 * main.c (main): No need to invoke signame_init(). Update copyright.
3391 * ABOUT-NLS: Removed.
3392 * gettext.c: Removed.
3393 * gettext.h: Get a simplified copy from the gettext package.
3395 * i18n/*.po: Moved to po/.
3398 * config/*: Created. Contains package configuration helper files.
3399 * config.guess, config.sub: Moved to config directory.
3401 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3402 Rework to use new-style autoconf features. Use the "external"
3403 mode for gettext. Make the build.sh config file conditional on
3404 whether build.sh.in exists, to avoid autoconf errors.
3405 * acinclude.m4: Removed almost all macros as being obsolete.
3406 Rewrote remaining macros to use AC_DEFINE.
3407 * acconfig.h: Removed.
3409 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3410 conditional to handle customs support. Remove special handling
3413 2002-04-20 Paul D. Smith <psmith@gnu.org>
3415 * function.c (func_call): Don't mark the argument variables $1,
3416 etc. as recursive. They've already been fully expanded so
3417 there's no need to do it again, and doing so strips escaped $'s.
3418 Reported by Sebastian Glita <glseba@yahoo.com>.
3420 * remake.c (notice_finished_file): Walk through double-colon
3421 entries via the prev field, not the next field!
3422 Reported by Greg McGary <greg@mcgary.org>.
3424 * main.c (main): If the user specifies -q and asks for a specific
3425 target which is a makefile, we got an assert. In that case it
3426 turns out we should continue normally instead.
3428 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3430 * i18n/he.po: Installed a new translation.
3432 2002-01-07 Paul D. Smith <psmith@gnu.org>
3434 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3436 2001-12-04 Paul D. Smith <psmith@gnu.org>
3438 * i18n/ja.po: Installed an updated translation.
3440 2001-09-06 Paul Eggert <eggert@twinsun.com>
3442 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3443 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3445 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3447 (main): Get rid of any avoidable limit on stack size.
3449 2001-09-04 Paul D. Smith <psmith@gnu.org>
3451 * i18n/da.po: Installed an updated translation.
3453 2001-08-03 Paul D. Smith <psmith@gnu.org>
3455 * i18n/fr.po: Installed an updated translation.
3456 Resolves Debian bug #106720.
3458 2001-06-13 Paul D. Smith <psmith@gnu.org>
3460 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3463 2001-06-11 Paul D. Smith <psmith@gnu.org>
3465 * i18n/ko.po: Installed a new translation.
3467 2001-05-06 Paul D. Smith <psmith@gnu.org>
3469 Modify the EINTR handling.
3471 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3472 the way in which we manage the file descriptor/signal handler race
3473 trap to be more efficient.
3475 2001-05-06 Paul Eggert <eggert@twinsun.com>
3477 Restart almost all system calls that are interrupted, instead
3478 of worrying about EINTR. The lone exception is the read() for
3481 * configure.in (HAVE_SA_RESTART): New macro.
3482 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3483 * main.c (main): Use SA_RESTART instead of the old,
3484 nonstandard SA_INTERRUPT.
3486 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3487 * main.c (bsd_signal): New function or macro,
3488 if the implementation doesn't supply it.
3489 (The bsd_signal function will be in POSIX 1003.1-200x.)
3490 (HANDLESIG): Remove.
3491 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3493 * make.h (EINTR_SET): Remove.
3494 (SA_RESTART): New macro.
3496 * arscan.c (ar_member_touch): Don't worry about EINTR.
3497 * function.c (func_shell): Likewise.
3498 * job.c (reap_children, free_child, new_job): Likewise.
3499 * main.c (main): Likewise.
3500 * remake.c (touch_file, name_mtime): Likewise.
3502 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3503 if fstat failed with errno!=EINTR, the error was ignored.
3505 * job.c (set_child_handler_action_flags): New function.
3506 (new_job): Use it to temporarily clear the SIGCHLD action flags
3507 while reading the token.
3509 2001-05-02 Paul D. Smith <psmith@gnu.org>
3511 * job.c (start_job_command): Don't add define/endef per-line flags
3512 to the top-level flags setting.
3514 2001-04-03 Paul D. Smith <psmith@gnu.org>
3516 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3517 bit on error, so check for odd return values, not non-0 return
3519 (VMS_get_member_info): Calculate the timezone differences correctly.
3520 Reported by John Fowler <jfowler@nyx.net>.
3523 2001-03-14 Paul D. Smith <psmith@gnu.org>
3525 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3526 value before invoking define_variable().
3527 Reported by John Fowler <jfowler@nyx.net>.
3529 2001-02-07 Paul D. Smith <psmith@gnu.org>
3531 * read.c (record_target_var): If we reset the variable due to a
3532 command-line variable setting overriding it, turn off the "append"
3535 2001-01-17 Paul D. Smith <psmith@gnu.org>
3537 * variable.c (lookup_variable) [VMS]: When getting values from the
3538 environment, allocate enough space for the _value_ plus escapes,
3539 not enough space for the name plus escapes :-/.
3540 Reported by John Fowler <jfowler@nyx.net>.
3542 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3543 warnings that make generates, so it doesn't look like an error.
3544 Reported by Karl Berry <karl@gnu.org>.
3547 Fix for PR/2020: Rework appended target-specific variables. I'm
3548 fairly confident this algorithm is finally correct.
3550 * expand.c (allocated_variable_append): Rewrite. Instead of
3551 expanding each appended variable then adding all the expanded
3552 strings together, we append all the unexpanded values going up
3553 through the variable set contexts, then expand the final result.
3554 This behaves just like non-target-specific appended variable
3555 values, while the old way didn't in various corner cases.
3556 (variable_append): New function: recursively append the unexpanded
3557 value of a variable, walking from the outermost variable scope to
3559 * variable.c (lookup_variable): Remove the code that looked up the
3560 variable set list if the found variable was "append". We don't
3562 (lookup_variable_in_set): Make this non-static so we can use it
3564 (try_variable_definition): Use lookup_variable_in_set() rather
3565 than faking out current_variable_set_list by hand (cleanup).
3566 * variable.h: Add a prototype for the now non-static
3567 lookup_variable_in_set().
3569 2000-11-17 Paul D. Smith <psmith@gnu.org>
3571 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3572 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3573 before throwing a fit.
3575 2000-11-17 Paul D. Smith <psmith@gnu.org>
3577 * read.c (readline): CRLF calculations had a hole, if you hit the
3578 buffer grow scenario just right. Reworked the algorithm to avoid
3579 the need for len or lastlen at all. Problem description with
3580 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3582 2000-10-24 Paul D. Smith <psmith@gnu.org>
3584 * gettext.c (SWAP): Declare this with the prototype, otherwise
3585 some systems don't work (non-32-bit? Reported for Cray T3E).
3586 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3588 2000-10-05 Paul D. Smith <psmith@gnu.org>
3590 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3591 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3593 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3595 2000-09-22 Paul D. Smith <psmith@gnu.org>
3597 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3598 parts of the real gettext.h here, and we expect to really include
3599 the real gettext.h later. If we keep this #define, it's ignored.
3601 2000-09-21 Paul D. Smith <psmith@gnu.org>
3603 * main.c (log_working_directory): Rework the text to use complete
3604 sentences, to make life simpler for the translators.
3606 2000-08-29 Paul D. Smith <psmith@gnu.org>
3608 * file.c (remove_intermediates): Print a debug message before we
3609 remove intermediate files, so the user (if she uses -d) knows
3612 2000-08-21 Paul D. Smith <psmith@gnu.org>
3614 * variable.c (try_variable_definition): Change how we handle
3615 target-specific append variable defns: instead of just setting the
3616 value, expand it as an append _but_ only within the current
3617 target's context. Otherwise we lose all but the last value if the
3618 variable is appended more than once within the current target
3619 context. Fixes PR/1831.
3621 2000-08-16 Paul D. Smith <psmith@gnu.org>
3623 * function.c (func_shell): Nul-terminate the buffer before
3624 printing an exec error message (just in case it's not!).
3625 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3627 2000-07-25 Paul D. Smith <psmith@gnu.org>
3629 * job.c (construct_command_argv_internal): Add "~" to the list of
3630 sh_chars[] which disallow optimizing out the shell call.
3632 2000-07-23 Paul Eggert <eggert@twinsun.com>
3634 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3635 supersedes --disable-nsec-timestamps.
3636 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3637 * README: Remove --disable-nsec-timestamps.
3639 * filedef.h (struct file.low_resolution_time): New member.
3640 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3641 * remake.c (update_file_1):
3642 Avoid spurious rebuilds due to low resolution time stamps,
3643 generalizing the earlier code that applied only to archive members.
3644 (f_mtime): Archive members always have low resolution time stamps.
3646 * configure.in: Remove --disable-nsec-timestamps, as this has
3647 been superseded by .LOW_RESOLUTION_TIME.
3649 2000-07-23 Paul Eggert <eggert@twinsun.com>
3651 * configure.in (enable_nsec_timestamps): Renamed from
3652 make_cv_nsec_timestamps, since enable/disable options
3653 shouldn't be cached.
3655 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3656 and Paul Eggert <eggert@twinsun.com>
3658 * file.c (file_timestamp_now):
3659 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3660 so that clock_gettime is not linked unless needed.
3662 * filedef.h (FILE_TIMESTAMP_HI_RES):
3663 Remove definition; "configure" now does this.
3665 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3666 to before high resolution file timestamp check,
3667 since that check now uses uintmax_t.
3668 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3669 high resolution file timestamps.
3670 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3671 so that we don't link in clock_gettime unnecessarily.
3673 2000-07-17 Paul D. Smith <psmith@gnu.org>
3675 * i18n/ja.po: New version of the translation file.
3677 2000-07-07 Paul D. Smith <psmith@gnu.org>
3679 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3680 the offset calculation.
3681 (name_mtime): Replace EINTR test with EINTR_SET macro.
3683 2000-07-07 Paul Eggert <eggert@twinsun.com>
3687 * remake.c (update_file_1):
3688 Avoid spurious rebuilds of archive members due to their
3689 timestamp resolution being only one second.
3690 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3691 the clock's resolution being lower than file timestamps'.
3692 When warning about future timestamps, report only the discrepancy,
3693 not the absolute value of the timestamp and the current time.
3695 * file.c (file_timestamp_now): New arg RESOLUTION.
3696 * filedef.h (file_timestamp_now): Likewise.
3697 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3699 2000-07-05 Paul D. Smith <psmith@gnu.org>
3701 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3702 to listp. Fixes PR/1793.
3704 2000-06-26 Paul Eggert <eggert@twinsun.com>
3706 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3708 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3710 * remake.c (f_mtime): Remove unused var memtime.
3712 2000-06-25 Martin Buchholz <martin@xemacs.org>
3714 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3715 Ran spell-check on make.texinfo.
3717 2000-06-23 Paul D. Smith <psmith@gnu.org>
3719 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3720 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3721 * make.h: Define these macros.
3723 * Version 3.79.1 released.
3725 * configure.in: Add a new option, --disable-nsec-timestamps, to
3726 avoid using sub-second timestamps on systems that support it. It
3727 can lead to problems, e.g. if your makefile relies on "cp -p".
3728 * README.template: Document the issue with "cp -p".
3730 * config.guess, config.sub: Updated.
