1 2003-11-02 Paul D. Smith <psmith@gnu.org>
3 * function.c (func_if): Strip all the trailing whitespace from the
4 condition, then don't expand it. Fixed bug # 5798.
6 * expand.c (recursively_expand_for_file): If we're expanding a
7 variable with no file context, then use the variable's context.
10 2003-10-21 Paul D. Smith <psmith@gnu.org>
12 * main.c (log_working_directory): Add newlines to printf()s.
14 * README.cvs: Add a note to ignore warnings during autoreconf.
16 * maintMakefile (po_repo): Set a new URL for PO file updates.
17 (get-config/config.guess get-config/config.sub): Get these files
18 from the Savannah config project instead of ftp.gnu.org.
20 2003-07-18 Paul D. Smith <psmith@gnu.org>
22 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
23 [WINDOWS32]: Initialize hash.
25 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
27 * dir.c (read_dirstream): Provide a workaround for broken versions of
28 the MinGW dirent structure.
30 2003-05-30 Earnie Boyd <earnie@users.sf.net>
32 * w32/include/dirent.h: Add __MINGW32__ filter.
34 2003-05-30 Earnie Boyd <earnie@users.sf.net>
36 * make.h: Add global declaration of *make_host.
37 * main.c (print_usage): Remove local declaration of *make_host.
38 (print_version): Display "This program built for ..." after Copyright
41 2003-05-30 Earnie Boyd <earnie@users.sf.net>
43 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
44 execution of "makeinfo --html make.texi".
46 2003-04-30 Paul D. Smith <psmith@gnu.org>
48 * build.template: Make some changes to maybe allow this script to
49 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
51 * README.OS2.template: New file for OS/2 support. Original
52 contributed by Andreas Buening.
53 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
56 2003-04-19 Paul D. Smith <psmith@gnu.org>
58 Fix bug #1405: allow a target to match multiple pattern-specific
61 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
62 variable.c, where they've always belonged.
63 * rule.h: Move the prototypes and struct pattern_var as well.
64 * variable.c (initialize_file_variables): Invoke
65 lookup_pattern_var() in a loop, until no more matches are found.
66 If a match is found, create a new variable set for the target's
67 pattern variables. Then merge the contents of each matching
68 pattern variable set into the target's pattern variable set.
69 (lookup_pattern_var): Change this function to be usable
70 in a loop. It takes a starting position: if NULL, start at the
71 beginning; if non-NULL, start with the pattern variable after that
72 position, and return the next matching pattern.
73 (create_pattern_var): Create a unique instance of
74 pattern-specific variables for every definition in the makefile.
75 Don't combine the same pattern together. This allows us to
76 process the variable handling properly even when the same pattern
77 is used multiple times.
78 (parse_variable_definition): New function: break out the parsing
79 of a variable definition line from try_variable_definition.
80 (try_variable_definition): Call parse_variable_definition to
82 (print_variable_data_base): Print out pattern-specific variables.
83 * variable.h (struct variable): Remember when a variable is
84 conditional. Also remember its flavor.
85 (struct pattern_var): Instead of keeping a variable set, we just
86 keep a single variable for each pattern.
87 * read.c (record_target_var): Each pattern variable contains only a
88 single variable, not a set, so create it properly.
89 * doc/make.texi (Pattern-specific): Document the new behavior.
91 2003-04-17 Paul D. Smith <psmith@gnu.org>
93 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
94 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
95 file/directory naming rules for VMS so I can't tell whether this
98 2003-04-09 Paul D. Smith <psmith@gnu.org>
100 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
101 DOS-style pathnames: backslash separators and drive specifiers.
103 2003-03-28 Paul D. Smith <psmith@gnu.org>
105 * file.c (snap_deps): If .SECONDARY with no targets is given, set
106 the intermediate flag on all targets. Fixes bug #2515.
108 2003-03-24 Paul D. Smith <psmith@gnu.org>
110 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
111 Upgrade to autoconf 2.57 and automake 1.7.3.
113 * job.c: More OS/2 changes from Andreas Buening.
115 * file.c (print_file): Fix variable initialization.
118 * remake.c (notice_finished_file):
120 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
121 some calls (like readdir()) return NULL in valid situations
122 without resetting errno. Fixes bug #2846.
124 2003-02-25 Paul D. Smith <psmith@gnu.org>
126 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
128 * job.c (_is_unixy_shell) [OS/2]: New function.
129 Set default shell to /bin/sh.
130 (reap_children): Close the job_rfd pipe here since we don't use a
132 (set_child_handler_action_flags): define this to empty on OS/2.
133 (start_job_command): Close the jobserver pipe and use
134 child_execute_job() instead of fork/exec.
135 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
136 rather than exec'ing, then reconfigure stdin/stdout.
137 (exec_command): Rewrite to use spawn instead of exec. Return the
140 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
141 in DOS. Handle the TEMP environment variable as in DOS. Don't
142 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
143 use -j in DOS mode. Use child_execute_job() instead of
146 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
149 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
150 prototypes that return values.
152 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
154 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
155 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
157 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
160 2003-02-24 Paul D. Smith <psmith@gnu.org>
162 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
163 * job.c (child_execute_job) [VMS]: New code for handling spawn().
164 (child_execute_job) [VMS]: Handle error status properly.
165 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
167 * function.c (func_shell): Use EINTRLOOP() while reading from the
168 subshell pipe (Fixes bug #2502).
169 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
171 * main.c (main): Ditto.
173 2003-01-30 Paul D. Smith <psmith@gnu.org>
175 * read.c (eval): eval() was not fully reentrant, because the
176 collapsed buffer was static. Change it to be an automatic
177 variable so that eval() can be invoked recursively.
179 (eval): Apply patch # 1022: fix memory reference error on long
180 target-specific variable lines.
181 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
183 * function.c (check_numeric): Combine the is_numeric() function
184 into this function, since it's only called from one place.
185 Constify this function. Have it print the incorrect string in the
186 error message. Fixes bug #2407.
187 (strip_whitespace): Constify.
189 * expand.c (expand_argument): Constify.
191 2003-01-29 Paul D. Smith <psmith@gnu.org>
193 Fix bug # 2169, also reported by other people on various systems.
195 * make.h: Some systems, such as Solaris and PTX, do not fully
196 implement POSIX-compliant SA_RESTART functionality; important
197 system calls like stat() and readdir() can still fail with EINTR
198 even if SA_RESTART has been set on the signal handler. So,
199 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
200 EINTR for system calls which return -1 or 0 (NULL), respectively,
202 Also, remove the old atomic_stat()/atomic_readdir() and
203 HAVE_BROKEN_RESTART handling.
205 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
207 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
208 * remake.c (touch_file): Ditto.
210 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
211 * read.c (construct_include_path): Ditto.
212 * remake.c (name_mtime): Ditto.
213 * vpath.c (selective_vpath_search): Ditto.
214 * dir.c (find_directory): Ditto.
216 (find_directory): Use ENULLLOOP() to wrap opendir().
217 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
219 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
220 atomic_readdir() handling.
222 2003-01-22 Paul D. Smith <psmith@gnu.org>
224 * function.c (func_call): Fix Bug #1744. If we're inside a
225 recursive invocation of $(call ...), mask any of the outer
226 invocation's arguments that aren't used by this one, so that this
227 invocation doesn't "inherit" them accidentally.
229 2002-12-05 Paul D. Smith <psmith@gnu.org>
231 * function.c (subst_expand): Valery Khamenia reported a
232 pathological performance hit when doing substitutions on very
233 large values with lots of words: turns out we were invoking
234 strlen() a ridiculous number of times. Instead of having each
235 call to sindex() call strlen() again, keep track of how much of
236 the text we've seen and pass the length to sindex().
238 2002-11-19 Paul D. Smith <psmith@gnu.org>
240 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
243 2002-11-16 Paul D. Smith <psmith@gnu.org>
245 * NMakefile.template (OBJS): Add hash.c object file.
246 * SMakefile.template (srcs): Ditto.
247 * Makefile.ami (objs): Ditto.
248 * build_w32.bat: Ditto.
250 * Makefile.DOS.template: Remove extra dependencies.
252 2002-10-25 Paul D. Smith <psmith@gnu.org>
254 * expand.c (install_variable_buffer): New function. Install a new
255 variable_buffer context and return the previous one.
256 (restore_variable_buffer): New function. Free the current
257 variable_buffer context and put a previously saved one back.
258 * variable.h: Prototypes for {install,restore}_variable_buffer.
259 * function.c (func_eval): Push a new variable_buffer context
260 before we eval, then restore the old one when we're done.
263 * read.c (install_conditionals): New function. Install a new
264 conditional context and return the previous one.
265 (restore_conditionals): New function. Free the current
266 conditional context and put a previously saved one back.
267 (eval): Use the {install,restore}_conditionals for "include"
269 (eval_buffer): Use {install,restore}_conditionals to preserve the
270 present conditional state before we evaluate the buffer.
273 * doc/make.texi (Quick Reference): Add references to $(eval ...)
275 (Recursion): Add a variable index entry for CURDIR.
277 * README.cvs: Update to appropriate versions.
278 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
279 don't need to copy loadavg.c: automake is smart enough to create
280 it for me. Still have a bug in automake related to ansi2knr tho.
282 2002-10-14 Paul D. Smith <psmith@gnu.org>
284 * remake.c (notice_finished_file): Only touch targets if they have
285 at least one command (as per POSIX). Resolve Bug #1418.
287 * *.c: Convert to using ANSI C-style function definitions.
288 * Makefile.am: Enable the ansi2knr feature of automake.
289 * configure.in: ditto.
291 2002-10-13 Paul D. Smith <psmith@gnu.org>
293 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
294 for automatic variable values like $^, etc. In the case of very
295 large lists of prerequisites this causes problems. Instead reuse
296 a static buffer (resizeable) for each variable.
298 * read.c (eval): Fix Bug #1391: allow "export" keyword in
299 target-specific variable definitions. Check for it and set an
301 (record_target_var): Set the export field to v_export if the
302 "exported" flag is set.
303 * doc/make.texi (Target-specific): Document the ability to use
306 * doc/make.texi: Change the name of the section on automatic
307 variables from "Automatic" to "Automatic Variables". Added text
308 clarifying the scope of automatic variables.
310 2002-10-04 Paul D. Smith <psmith@gnu.org>
312 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
314 (record_files): Ditto.
316 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
317 the search for the '=' to only within the enclosing parens.
319 2002-10-03 Paul D. Smith <psmith@gnu.org>
321 Version 3.80 released.
323 * dir.c: Change hash functions to use K&R function definition style.
328 Update to automake 1.7.
330 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
331 (pdf): Remove this target as automake now provides one.
333 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
335 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
337 * makefile.com: Updates for GNU make 3.80.
338 * makefile.vms: Ditto.
340 2002-09-23 Paul D. Smith <psmith@gnu.org>
342 * read.c (enum make_word_type): Remove w_comment.
343 (get_next_mword): Don't treat comment characters as special; where
344 this function is used we will never see a comment (it's stripped
345 before we get here) and treating comments specially means that
346 targets like "foo\#bar" aren't handled properly.
348 2002-09-18 Paul D. Smith <psmith@gnu.org>
350 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
352 * read.c (eval): Expansion of arguments to export/unexport was
353 ignoring all arguments after the first one. Change the algorithm
354 to expand the whole line once, then parse the results.
356 2002-09-17 Paul D. Smith <psmith@gnu.org>
358 Fix Bug #940 (plus another bug I found while looking at this):
360 * read.c (record_target_var): enter_file() will add a new entry if
361 it's a double-colon target: we don't want to do that in this
362 situation. Invoke lookup_file() and only enter_file() if it does
363 not already exist. If the file we get back is a double-colon then
364 add this variable to the "root" double-colon target.
366 * variable.c (initialize_file_variables): If this file is a
367 double-colon target but is not the "root" target, then initialize
368 the root and make the root's variable list the parent of our
371 2002-09-13 Paul D. Smith <psmith@gnu.org>
373 * doc/make.texi (MAKE Variable): Add some indexing for "+".
375 * hash.c (round_up_2): Get rid of a warning.
377 2002-09-12 Paul D. Smith <psmith@gnu.org>
379 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
380 so it doesn't complain about getloadavg.c.
382 * commands.c (set_file_variables): Make sure we always alloca() at
383 least 1 character for the value of $? (for '\0').
385 2002-09-11 Paul D. Smith <psmith@gnu.org>
387 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
388 macro to use RESULT instead of the incorrect _RESULT_.
390 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
391 and atomic_readdir(). We need to #include dirent.h to get this to
393 * misc.c (atomic_readdir): Fix typos.
395 2002-09-10 Paul D. Smith <psmith@gnu.org>
397 * read.c (eval): Expand variable lists given to export and
398 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
399 (conditional_line): Ditto for "ifdef". Fixes bug #103.
401 * doc/make.texi (Variables/Recursion): Document this.
402 (Conditional Syntax): And here.
404 2002-09-09 Paul D. Smith <psmith@gnu.org>
406 * configure.in: Check for memmove().
408 2002-09-07 Paul D. Smith <psmith@gnu.org>
410 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
411 Michael Sterrett <msterret@coat.com> reports that while it has
412 SA_RESTART, it does not work properly.
414 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
415 that invokes stat() and loops to do it again if it returns EINTR.
416 (atomic_readdir): Ditto, with readdir().
418 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
419 and readdir() to atomic_stat() and atomic_readdir().
421 2002-09-04 Paul D. Smith <psmith@gnu.org>
423 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
424 reports that GNU make sometimes doesn't recognize that targets can
425 be made, when directories can be created as prerequisites. He
426 reports that changing the order of predicates in the DEP->changed
427 flag test so that lookup_file() is always performed, solves this
430 2002-08-08 Paul D. Smith <psmith@gnu.org>
432 * configure.in: Require a newer version of gettext.
434 * misc.c (perror_with_name): Translate the format string (for
435 right-to-left language support).
436 (pfatal_with_name): Ditto.
438 * main.c: Create a static array of strings to store the usage
439 text. This is done to facilitate translations.
440 (struct command_switch): Remove argdesc and description fields.
441 (switches): Remove values for obsolete fields.
442 (print_usage): Print each element of the usage array.
444 * hash.c: Change function definitions to be K&R style.
446 2002-08-02 Paul D. Smith <psmith@gnu.org>
448 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
449 this one because it's too hard to get right. We'll look at it for
451 * main.c (main): Don't create the .TARGETS variable.
452 * variable.c (handle_special_var): Don't handle .TARGETS.
454 2002-08-01 Paul D. Smith <psmith@gnu.org>
456 * main.c (switches): Add a new option, -B (--always-make). If
457 specified, make will rebuild all targets that it encounters even
458 if they don't appear to be out of date.
459 (always_make_flag): New flag.
460 * make.h: Extern always_make_flag.
461 * remake.c (update_file_1): Check always_make_flag; if it's set we
462 will always rebuild any target we can, even if none of its
463 prerequisites are newer.
466 * doc/make.texi (Shell Function): Make it clear that make
467 variables marked as "export" are not passed to instances of the
470 Add new introspection variable .VARIABLES and .TARGETS.
472 * variable.c (handle_special_var): New function. If the variable
473 reference passed in is "special" (.VARIABLES or .TARGETS),
474 calculate the new value if necessary. .VARIABLES is handled here:
475 walk through the hash of defined variables and construct a value
476 which is a list of the names. .TARGETS is handled by
478 (lookup_variable): Invoke handle_special_var().
479 * file.c (build_target_list): Walk through the hask of known files
480 and construct a list of the names of all the ones marked as
482 * main.c (main): Initialize them to empty (and as simple variables).
483 * doc/make.texi (Special Variables): Document them.
484 * NEWS: Mention them.
486 * variable.h (struct variable): Add a new flag "exportable" which
487 is true if the variable name is valid for export.
488 * variable.c (define_variable_in_set): Set "exportable" when a new
490 (target_environment): Use the "exportable" flag instead of
491 re-checking the name here... an efficiency improvement.
493 2002-07-31 Paul D. Smith <psmith@gnu.org>
495 * config.h-vms.template: Updates to build on VMS. Thanks to
496 Brian_Benning@aksteel.com for helping verify the build.
497 * makefile.com: Build the new hash.c file.
498 * hash.h: Use strcpmi(), not stricmp(), in the
499 HAVE_CASE_INSENSITIVE_FS case.
501 2002-07-30 Paul D. Smith <psmith@gnu.org>
503 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
504 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
505 Reported by <Brian_Benning@aksteel.com>.
507 2002-07-10 Paul D. Smith <psmith@gnu.org>
509 * variable.c (pop_variable_scope): Remove variable made unused by
510 new hash infrastructure.
511 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
512 comparisons as well as name comparisons.
513 * variable.h: Add a prototype for new hash_init_function_table().
514 * file.c (lookup_file): Remove variables made unused by new hash
516 * dir.c (directory_contents_hash_2): Missing return of hash value.
517 (dir_contents_file_exists_p): Remove variables made unused by new
521 Installed Greg McGary's integration of the hash functions from the
522 GNU id-utils package:
524 2002-07-10 Greg McGary <greg@mcgary.org>
526 * scripts/functions/filter-out: Add literals to to the
527 pattern space in order to add complexity, and trigger
528 use of an internal hash table. Fix documentation strings.
529 * scripts/targets/INTERMEDIATE: Reverse order of files
530 passed to expected `rm' command.
532 2002-07-10 Greg McGary <greg@mcgary.org>
534 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h

536 * hash.h: New file, taken from id-utils.
538 * make.h (HASH, HASHI): Remove macros.
539 (find_char_unquote): Change arglist in decl.
540 (hash_init_directories): New function decl.
541 * variable.h (hash.h): New #include.
542 (MAKELEVEL_NAME, MAKELEVEL_LENGTH): New constants.
543 * filedef.h (hash.h): New #include.
544 (struct file) [next]: Remove member.
545 (file_hash_enter): Remove function decl.
546 (init_hash_files): New function decl.
548 * ar.c (ar_name): Delay call to strlen until needed.
549 * main.c (initialize_global_hash_tables): New function.
550 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH.
551 * misc.c (remove_comments): Pass char constants to find_char_unquote.

557 (directory_contents_hash_1, directory_contents_hash_2,
558 directory_contents_hash_cmp): New functions.
559 (directories_contents): Change type to `struct hash_table'.
560 (struct directory) [next]: Remove member.

591 (struct a_pattern): New struct.
592 (func_filter_filterout): Pass through patterns noting boundaries
593 and '%', if present. Note a_word length. Use a hash table if
594 arglists are large enough to justify cost.

603 (uniquize_deps): Use hash table to efficiently identify duplicates.
604 (find_char_unquote): Accept two char-constant stop chars, rather
605 than a string constant, avoiding zillions of calls to strchr.
606 Tighten inner search loops to test only for desired delimiters.

626 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
627 prerequisite list. A real SysV make will expand the entire
628 prerequisites list _twice_: we don't do that as it's a big
629 backward-compatibility problem. We only replace those specific
632 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
633 references left in the list of prerequisites. Check for .POSIX as
634 we record targets, so we can disable non-POSIX behavior while
635 reading makefiles as well as running them.
636 (eval): Check the prerequisite list to see if we have anything
637 that looks like a SysV prerequisite variable reference.
639 2002-07-09 Paul D. Smith <psmith@gnu.org>
641 * doc/make.texi (Prerequisite Types): Add a new section describing
642 order-only prerequisites.
644 * read.c (uniquize_deps): If we have the same file as both a
645 normal and order-only prereq, get rid of the order-only prereq,
646 since the normal one supersedes it.
648 2002-07-08 Paul D. Smith <psmith@gnu.org>
650 * AUTHORS: Added Greg McGary to the AUTHORS file.
651 * NEWS: Blurbed order-only prerequisites.
652 * file.c (print_file): Show order-only deps properly when printing
655 * maintMakefile: Add "update" targets for wget'ing the latest
656 versions of various external files. Taken from Makefile.maint in
659 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
660 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
662 2002-07-07 Paul D. Smith <psmith@gnu.org>
664 * po/*.po: Remove. We'll use wget to retrieve them at release
667 * variable.c (do_variable_definition) [W32]: On W32 using cmd
668 rather than a shell you get an exception. Make sure we look up
669 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
671 * remake.c (notice_finished_file): Fix handling of -t flag.
672 Patch provided by Henning Makholm <henning@makholm.net>.
674 * implicit.c (pattern_search): Some systems apparently run short
675 of stack space, and using alloca() in this function caused an
676 overrun. I modified it to use xmalloc() on the two variables
677 which seemed like they might get large. Fixes Bug #476.
679 * main.c (print_version): Update copyright notice to conform with
681 (print_usage): Update help output.
683 * function.c (func_eval): Create a new make function, $(eval
684 ...). Expand the arguments, put them into a buffer, then invoke
685 eval_buffer() on the resulting string.
686 (func_quote): Create a new function, $(quote VARNAME). Inserts
687 the value of the variable VARNAME without expanding it any
690 * read.c (struct ebuffer): Change the linebuffer structure to an
691 "eval buffer", which can be either a file or a buffer.
692 (eval_makefile): Move the code in the old read_makefile() which
693 located a makefile into here: create a struct ebuffer with that
694 information. Have it invoke the new function eval() with that
696 (eval_buffer): Create a new function that creates a struct ebuffer
697 that holds a string buffer instead of a file. Have it invoke
698 eval() with that ebuffer.
699 (eval): New function that contains the guts of the old
700 read_makefile() function: this function parses makefiles. Obtains
701 data to parse from the provided ebuffer. Some modifications to
702 make the flow of the function cleaner and clearer. Still could
703 use some work here...
704 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
705 contents of the define/endef variable from the ebuffer.
706 (readstring): Read the next line from a string-style ebuffer.
707 (readline): Read the next line from an ebuffer. If it's a string
708 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
711 * dep.h (eval_buffer): Prototype eval_buffer();
713 * variable.c (do_variable_definition): Make sure that all
714 non-target-specific variables are registered in the global set.
715 If we're invoked from an $(eval ...) we might be inside a $(call
716 ...) or other function which has pushed a variable scope; we still
717 want to define our variables from evaluated makefile code in the
720 2002-07-03 Greg McGary <greg@mcgary.org>
722 * dep.h (struct dep) [ignore_mtime]: New member.
723 [changed]: convert to a bitfield.
724 * implicit.c (pattern_search): Zero ignore_mtime.
725 * main.c (main, handle_non_switch_argument): Likewise.
726 * rule.c (convert_suffix_rule): Likewise.
727 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
728 (read_makefile): Parse '|' in prerequisite list.
729 (uniquize_deps): Consider ignore_mtime when comparing deps.
730 * remake.c (update_file_1, check_dep): Don't force remake for
731 dependencies that have d->ignore_mtime.
732 * commands.c (FILE_LIST_SEPARATOR): New constant.
733 (set_file_variables): Don't include a
734 prerequisite in $+, $^ or $? if d->ignore_mtime.
737 2002-06-18 Paul D. Smith <psmith@gnu.org>
739 * make.texinfo: Updates for next revision. New date/rev/etc.
740 Recreate all Info menus. Change license on the manual to the GNU
741 Free Documentation License. A number of typos.
742 (Variables Simplify): Don't use "-" before it's defined.
743 (Automatic Prerequisites): Rewrite the target example to work
744 properly if the compile fails. Remove incorrect comments about
745 how "set -e" behaves.
746 (Text Functions): Move the "word", "wordlist", "words", and
747 "firstword" functions here, from "File Name Functions".
748 * make-stds.texi: Update from latest GNU version.
749 * fdl.texi: (created) Import the latest GNU version.
751 2002-06-06 Paul D. Smith <psmith@gnu.org>
753 * variable.c (do_variable_definition): New function: extract the
754 part of try_variable_definition() that actually sets the value
755 into a separate function.
756 (try_variable_definition): Call do_variable_definition() after
757 parsing the variable definition string.
758 (define_variable_in_set): Make the name argument const.
760 * variable.h (enum variable_flavor): Make public.
761 (do_variable_definition): Create prototype.
763 * read.c (read_all_makefiles): Create a new built-in variable,
765 (read_makefile): Add each makefile read in to this variable value.
767 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
769 * Makefile.DOS.template: Tweak according to changes in the
770 distribution. Add back the dependencies of *.o files.
772 * configh.dos.template: Synchronize with config.h.in.
774 2002-05-09 Paul D. Smith <psmith@gnu.org>
776 * file.c (file_timestamp_now): Use K&R function declaration.
778 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
779 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
780 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
781 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
782 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
783 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
784 nlist.n_name is a pointer rather than an array.
786 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
787 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
788 * configure.in: Use it instead of the old version.
790 * main.c (main): Prefer setvbuf() to setlinebuf().
792 2002-05-08 Paul D. Smith <psmith@gnu.org>
794 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
795 (loadavg_LDADD): Ditto.
797 2002-04-29 Paul D. Smith <psmith@gnu.org>
799 * expand.c (recursively_expand_for_file): Rename
800 recursively_expand() to recursively_expand_for_file() and provide
801 an extra argument, struct file. If the argument is provided, set
802 the variable scope to that of the file before expanding.
803 * variable.h (recursively_expand): Make this a macro that invokes
804 recursively_expand_for_file() with a NULL file pointer.
805 * variable.c (target_environment): Call the renamed function and
806 provide the current file context.
807 Fixes Debian bug #144306.
809 2002-04-28 Paul D. Smith <psmith@gnu.org>
811 Allow $(call ...) user-defined variables to be self-referencing
812 without throwing an error. Allows implementation of transitive
813 closures, among other possibly useful things.
814 Requested by: Philip Guenther <guenther@sendmail.com>
816 * variable.h (struct variable): Add a new field: exp_count, and
817 new macros to hold its size and maximum value.
818 (warn_undefined): Make this a macro.
819 * variable.c (define_variable_in_set): Initialize it.
820 * expand.c (recursively_expand): If we detect recursive expansion
821 of a variable, check the exp_count field. If it's greater than 0
822 allow the recursion and decrement the count.
823 (warn_undefined): Remove this (now a macro in variable.h).
824 * function.c (func_call): Before we expand the user-defined
825 function, modify its exp_count field to contain the maximum
826 number of recursive calls we'll allow. After the call, reset it
829 2002-04-21 Paul D. Smith <psmith@gnu.org>
831 Modified to use latest autoconf (2.53), automake (1.6.1), and
832 gettext (0.11.1). We're using gettext's new "external" support,
833 to avoid including libintl source with GNU make.
835 * README.cvs: New file. Explain how to build GNU make from CVS.
837 * configure.in: Modify checking for the system glob library.
838 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
839 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
840 etc. will manage it correctly). Set an automake conditional
841 USE_LOCAL_GLOB to decide whether to compile the glob library.
843 * getloadavg.c (main): Include make.h in the "TEST" program to
846 * Makefile.am: Remove special rules for loadavg. Replace them
847 with Automake capabilities for building extra programs.
849 * signame.c: This file does nothing if the system provide
850 strsignal(). If not, it implements strsignal(). If the system
851 doesn't define sys_siglist, then we make our own; otherwise we use
853 * signame.h: Removed.
855 * main.c (main): No need to invoke signame_init(). Update copyright.
857 * ABOUT-NLS: Removed.
858 * gettext.c: Removed.
859 * gettext.h: Get a simplified copy from the gettext package.
861 * i18n/*.po: Moved to po/.
864 * config/*: Created. Contains package configuration helper files.
865 * config.guess, config.sub: Moved to config directory.
867 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
868 Rework to use new-style autoconf features. Use the "external"
869 mode for gettext. Make the build.sh config file conditional on
870 whether build.sh.in exists, to avoid autoconf errors.
871 * acinclude.m4: Removed almost all macros as being obsolete.
872 Rewrote remaining macros to use AC_DEFINE.
873 * acconfig.h: Removed.
875 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
876 conditional to handle customs support. Remove special handling
879 2002-04-20 Paul D. Smith <psmith@gnu.org>
881 * function.c (func_call): Don't mark the argument variables $1,
882 etc. as recursive. They've already been fully expanded so
883 there's no need to do it again, and doing so strips escaped $'s.
884 Reported by Sebastian Glita <glseba@yahoo.com>.
886 * remake.c (notice_finished_file): Walk through double-colon
887 entries via the prev field, not the next field!
888 Reported by Greg McGary <greg@mcgary.org>.
890 * main.c (main): If the user specifies -q and asks for a specific
891 target which is a makefile, we got an assert. In that case it
892 turns out we should continue normally instead.
894 * i18n/de.po, i18n/fr.po: Installed an updated translation.
896 * i18n/he.po: Installed a new translation.
898 2002-01-07 Paul D. Smith <psmith@gnu.org>
900 * i18n/es.po, i18n/ru.po: Installed an updated translation.
902 2001-12-04 Paul D. Smith <psmith@gnu.org>
904 * i18n/ja.po: Installed an updated translation.
906 2001-09-04 Paul D. Smith <psmith@gnu.org>
908 * i18n/da.po: Installed an updated translation.
910 2001-08-03 Paul D. Smith <psmith@gnu.org>
912 * i18n/fr.po: Installed an updated translation.
913 Resolves Debian bug #106720.
915 2001-06-13 Paul D. Smith <psmith@gnu.org>
917 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
920 2001-06-11 Paul D. Smith <psmith@gnu.org>
922 * i18n/ko.po: Installed a new translation.
924 2001-05-06 Paul D. Smith <psmith@gnu.org>
926 Modify the EINTR handling.
928 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
929 the way in which we manage the file descriptor/signal handler race
930 trap to be more efficient.
932 2001-05-06 Paul Eggert <eggert@twinsun.com>
934 Restart almost all system calls that are interrupted, instead
935 of worrying about EINTR. The lone exception is the read() for
938 * configure.in (HAVE_SA_RESTART): New macro.
939 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
940 * main.c (main): Use SA_RESTART instead of the old,
941 nonstandard SA_INTERRUPT.
943 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
944 * main.c (bsd_signal): New function or macro,
945 if the implementation doesn't supply it.
946 (The bsd_signal function will be in POSIX 1003.1-200x.)
948 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
950 * make.h (EINTR_SET): Remove.
951 (SA_RESTART): New macro.
953 * arscan.c (ar_member_touch): Don't worry about EINTR.
954 * function.c (func_shell): Likewise.
955 * job.c (reap_children, free_child, new_job): Likewise.
956 * main.c (main): Likewise.
957 * remake.c (touch_file, name_mtime): Likewise.
959 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
960 if fstat failed with errno!=EINTR, the error was ignored.
962 * job.c (set_child_handler_action_flags): New function.
963 (new_job): Use it to temporarily clear the SIGCHLD action flags
964 while reading the token.
966 2001-05-02 Paul D. Smith <psmith@gnu.org>
968 * job.c (start_job_command): Don't add define/endef per-line flags
969 to the top-level flags setting.
971 2001-04-03 Paul D. Smith <psmith@gnu.org>
973 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
974 bit on error, so check for odd return values, not non-0 return
976 (VMS_get_member_info): Calculate the timezone differences correctly.
977 Reported by John Fowler <jfowler@nyx.net>.
980 2001-03-14 Paul D. Smith <psmith@gnu.org>
982 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
983 value before invoking define_variable().
984 Reported by John Fowler <jfowler@nyx.net>.
986 2001-02-07 Paul D. Smith <psmith@gnu.org>
988 * read.c (record_target_var): If we reset the variable due to a
989 command-line variable setting overriding it, turn off the "append"
992 2001-01-17 Paul D. Smith <psmith@gnu.org>
994 * variable.c (lookup_variable) [VMS]: When getting values from the
995 environment, allocate enough space for the _value_ plus escapes,
996 not enough space for the name plus escapes :-/.
997 Reported by John Fowler <jfowler@nyx.net>.
999 * remake.c (f_mtime): Removed the "***" prefix from the mod time
1000 warnings that make generates, so it doesn't look like an error.
1001 Reported by Karl Berry <karl@gnu.org>.
1004 Fix for PR/2020: Rework appended target-specific variables. I'm
1005 fairly confident this algorithm is finally correct.
1007 * expand.c (allocated_variable_append): Rewrite. Instead of
1008 expanding each appended variable then adding all the expanded
1009 strings together, we append all the unexpanded values going up
1010 through the variable set contexts, then expand the final result.
1011 This behaves just like non-target-specific appended variable
1012 values, while the old way didn't in various corner cases.
1013 (variable_append): New function: recursively append the unexpanded
1014 value of a variable, walking from the outermost variable scope to
1016 * variable.c (lookup_variable): Remove the code that looked up the
1017 variable set list if the found variable was "append". We don't
1019 (lookup_variable_in_set): Make this non-static so we can use it
1021 (try_variable_definition): Use lookup_variable_in_set() rather
1022 than faking out current_variable_set_list by hand (cleanup).
1023 * variable.h: Add a prototype for the now non-static
1024 lookup_variable_in_set().
1026 2000-11-17 Paul D. Smith <psmith@gnu.org>
1028 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
1029 WINDOWS32 port to assume timestamps can be up to 3 seconds away
1030 before throwing a fit.
1032 2000-11-17 Paul D. Smith <psmith@gnu.org>
1034 * read.c (readline): CRLF calculations had a hole, if you hit the
1035 buffer grow scenario just right. Reworked the algorithm to avoid
1036 the need for len or lastlen at all. Problem description with
1037 sample code chages provided by Chris Faylor <cgf@redhat.com>.
1039 2000-10-24 Paul D. Smith <psmith@gnu.org>
1041 * gettext.c (SWAP): Declare this with the prototype, otherwise
1042 some systems don't work (non-32-bit? Reported for Cray T3E).
1043 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
1045 2000-10-05 Paul D. Smith <psmith@gnu.org>
1047 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
1048 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
1050 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
1052 2000-09-22 Paul D. Smith <psmith@gnu.org>
1054 * gettext.c: Don't #define _GETTEXT_H here; we only include some
1055 parts of the real gettext.h here, and we expect to really include
1056 the real gettext.h later. If we keep this #define, it's ignored.
1058 2000-09-21 Paul D. Smith <psmith@gnu.org>
1060 * main.c (log_working_directory): Rework the text to use complete
1061 sentences, to make life simpler for the translators.
1063 2000-08-29 Paul D. Smith <psmith@gnu.org>
1065 * file.c (remove_intermediates): Print a debug message before we
1066 remove intermediate files, so the user (if she uses -d) knows
1069 2000-08-21 Paul D. Smith <psmith@gnu.org>
1071 * variable.c (try_variable_definition): Change how we handle
1072 target-specific append variable defns: instead of just setting the
1073 value, expand it as an append _but_ only within the current
1074 target's context. Otherwise we lose all but the last value if the
1075 variable is appended more than once within the current target
1076 context. Fixes PR/1831.
1078 2000-08-16 Paul D. Smith <psmith@gnu.org>
1080 * function.c (func_shell): Nul-terminate the buffer before
1081 printing an exec error message (just in case it's not!).
1082 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
1084 2000-07-25 Paul D. Smith <psmith@gnu.org>
1086 * job.c (construct_command_argv_internal): Add "~" to the list of
1087 sh_chars[] which disallow optimizing out the shell call.
1089 2000-07-23 Paul Eggert <eggert@twinsun.com>
1091 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
1092 supersedes --disable-nsec-timestamps.
1093 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
1094 * README: Remove --disable-nsec-timestamps.
1096 * filedef.h (struct file.low_resolution_time): New member.
1097 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
1098 * remake.c (update_file_1):
1099 Avoid spurious rebuilds due to low resolution time stamps,
1100 generalizing the earlier code that applied only to archive members.
1101 (f_mtime): Archive members always have low resolution time stamps.
1103 * configure.in: Remove --disable-nsec-timestamps, as this has
1104 been superseded by .LOW_RESOLUTION_TIME.
1106 2000-07-23 Paul Eggert <eggert@twinsun.com>
1108 * configure.in (enable_nsec_timestamps): Renamed from
1109 make_cv_nsec_timestamps, since enable/disable options
1110 shouldn't be cached.
1112 2000-07-23 Bruno Haible <haible@clisp.cons.org>
1113 and Paul Eggert <eggert@twinsun.com>
1115 * file.c (file_timestamp_now):
1116 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
1117 so that clock_gettime is not linked unless needed.
1119 * filedef.h (FILE_TIMESTAMP_HI_RES):
1120 Remove definition; "configure" now does this.
1122 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
1123 to before high resolution file timestamp check,
1124 since that check now uses uintmax_t.
1125 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
1126 high resolution file timestamps.
1127 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
1128 so that we don't link in clock_gettime unnecessarily.
1130 2000-07-17 Paul D. Smith <psmith@gnu.org>
1132 * i18n/ja.po: New version of the translation file.
1134 2000-07-07 Paul D. Smith <psmith@gnu.org>
1136 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
1137 the offset calculation.
1138 (name_mtime): Replace EINTR test with EINTR_SET macro.
1140 2000-07-07 Paul Eggert <eggert@twinsun.com>
1144 * remake.c (update_file_1):
1145 Avoid spurious rebuilds of archive members due to their
1146 timestamp resolution being only one second.
1147 (f_mtime): Avoid spurious warnings of timestamps in the future due to
1148 the clock's resolution being lower than file timestamps'.
1149 When warning about future timestamps, report only the discrepancy,
1150 not the absolute value of the timestamp and the current time.
1152 * file.c (file_timestamp_now): New arg RESOLUTION.
1153 * filedef.h (file_timestamp_now): Likewise.
1154 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
1156 2000-07-05 Paul D. Smith <psmith@gnu.org>
1158 * variable.c (lookup_variable) [VMS]: Remove vestigial references
1159 to listp. Fixes PR/1793.
1161 2000-06-26 Paul Eggert <eggert@twinsun.com>
1163 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
1165 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
1167 * remake.c (f_mtime): Remove unused var memtime.
1169 2000-06-25 Martin Buchholz <martin@xemacs.org>
1171 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
1172 Ran spell-check on make.texinfo.
1174 2000-06-23 Paul D. Smith <psmith@gnu.org>
1176 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
1177 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
1178 * make.h: Define these macros.
1180 * Version 3.79.1 released.
1182 * configure.in: Add a new option, --disable-nsec-timestamps, to
1183 avoid using sub-second timestamps on systems that support it. It
1184 can lead to problems, e.g. if your makefile relies on "cp -p".
1185 * README.template: Document the issue with "cp -p".
1187 * config.guess, config.sub: Updated.
