1 2005-02-09 Paul D. Smith <psmith@gnu.org>
3 * maintMakefile: Update the CVS download URL to simplify them.
4 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
5 downloading the .texi files from Savannah now.
7 2005-02-01 Paul D. Smith <psmith@gnu.org>
9 * maintMakefile (po_repo): Update the GNU translation site URL.
11 2004-12-01 Paul D. Smith <psmith@gnu.org>
13 * main.c (main): Change char* env_shell to struct variable shell_var.
14 * variable.c (target_environment): Use new shell_var.
16 2004-11-30 Paul D. Smith <psmith@gnu.org>
18 * configure.in: The old way we avoided creating build.sh from
19 build.sh.in before build.sh.in exists doesn't work anymore; we
20 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
21 the help!). This also keeps automake from complaining.
22 * Makefile.am (README): Add a dummy target so automake won't
23 complain that this file doesn't exist when we checkout from CVS.
24 * maintMakefile (.dep_segment): Rewrite this rule since newer
25 versions of automake don't provide DEP_FILES.
27 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
29 Implementation of `realpath' and `abspath' built-in functions.
31 * configure.in: Check for realpath.
32 * function.c (abspath): Return an absolute file name that does
33 not contain any `.' or `..' components, nor repeated `/'.
34 * function.c (func_abspath): For each name call abspath.
35 * function.c (func_realpath): For each name call realpath
36 from libc or delegate to abspath if realpath is not available.
37 * doc/make.texi (Functions for File Names): Document new functions.
38 * doc/make.texi (Quick Reference): Ditto.
40 2004-11-28 Paul D. Smith <psmith@gnu.org>
42 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
43 arguments. Fixes bug #10252.
45 Fix for bug #1276: Handle SHELL according to POSIX requirements.
47 * main.c (main): Set SHELL to v_noexport by default. Remember the
48 original environment setting of SHELL in the env_shell variable.
49 * main.h: Export new env_shell variable.
50 * variable.c (target_environment): If we find a v_noexport
51 variable for SHELL, add a SHELL variable with the env_shell value.
52 * doc/make.texi (Quick Reference): Document the POSIX behavior.
53 * doc/make.texi (Variables/Recursion): Ditto.
55 2004-11-28 Paul D. Smith <psmith@gnu.org>
57 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
58 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
59 Patch by Alessandro Vesely.
61 2004-11-12 Paul D. Smith <psmith@gnu.org>
63 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
64 the command line if it's inside a string.
65 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
67 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
69 * function.c (func_lastword): New function: return last word
70 from the list of words.
71 * doc/make.texi: Document $(lastword ). Fix broken links in
72 Quick Reference section.
74 2004-10-06 Paul D. Smith <psmith@gnu.org>
76 Apply patch from Alessandro Vesely, provided with bug # 9748.
77 Fix use of tmpnam() to work with Borland C.
79 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
80 construction of a temporary filename, and call new function
81 create_batch_filename().
82 (create_batch_filename) [WINDOWS32]: New function to create a
85 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
87 * read.c (record_target_var): Expand simple pattern-specific
89 * variable.c (initialize_file_variables): Do not expand simple
90 pattern-specific variable.
92 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
94 * remake.c (update_file_1): When rebuilding makefiles inherit
95 dontcare flag from a target that triggered update.
97 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
99 * variable.c (initialize_file_variables): Mark pattern-specific
100 variable as a per-target and copy export status.
102 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
104 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
106 * implicit.c (pattern_search): When considering an implicit rule's
107 prerequisite check that it is actually a target rather then
108 just an entry in the file hashtable.
110 2004-09-21 Paul D. Smith <psmith@gnu.org>
112 * read.c (readstring): Fix some logic errors in backslash handling.
113 (eval): Remove some unnecessary processing in buffer handling.
114 (record_target_var): Assert that parse_variable_definition() succeeded.
115 Reported by: Markus Mauhart <qwe123@chello.at>.
117 * misc.c: Removed the sindex() function. All instances of this
118 function were trivially replaceable by the standard strstr()
119 function, and that function will always have better (or certainly
120 no worse) performance than the very simple-minded algorithm
121 sindex() used. This can matter with complex makefiles.
122 * make.h: Remove the prototype for sindex().
123 * function.c (subst_expand): Convert sindex() call to strstr().
124 This means we no longer need to track the TLEN value so remove that.
125 (func_findstring): Convert sindex() to strstr().
126 * commands.c (chop_commands): Convert sindex() calls to strstr().
127 Suggested by: Markus Mauhart <qwe123@chello.at>.
129 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
130 idea behind Savannah Patch #3144 from david.baird@homemail.com.
131 If SHELL is set to CMD.EXE then assume it's batch-mode and
132 non-unixy. I wrote the code differently from the patch, though,
133 to make it safer. This also resolves bug #9174.
135 2004-09-20 Paul D. Smith <psmith@gnu.org>
137 * expand.c (variable_expand_string): Modify to invoke
138 patsubst_expand() instead of subst_expand(); the latter didn't
139 handle suffix patterns correctly.
140 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
141 was used only from variable_expand_string() and is no longer used
143 (func_subst): Ditto, on call to subst_expand().
144 (patsubst_expand): Require the percent pointers to point to the
145 character after the %, not to the % itself.
146 * read.c (record_files): New call criteria for patsubst_expand().
147 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
148 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
150 2004-09-19 Paul D. Smith <psmith@gnu.org>
152 * function.c (subst_expand): Fix a check in by_word: look for a
153 previous blank if we're beyond the beginning of the string, not
154 the beginning of the word.
155 Bugs reported by Markus Mauhart <qwe123@chello.at>.
157 2004-05-16 Paul D. Smith <psmith@gnu.org>
159 * remake.c (update_goal_chain): Change the argument specifying
160 whether we're rebuilding makefiles to be a global variable,
161 REBUILDING_MAKEFILES.
162 (complain): Extract the code that complains about no rules to make
163 a target into a separate function.
164 (update_file_1): If we tried to rebuild a file during the makefile
165 rebuild phase and it was dontcare, then no message was printed.
166 If we then try to build the same file during the normal build,
167 print a message this time.
168 (remake_file): Don't complain about un-remake-able files when
169 we're rebuilding makefiles.
171 2004-05-11 Paul D. Smith <psmith@gnu.org>
173 * job.c (construct_command_argv_internal): OS/2 patches from
174 Andreas Buening <andreas.buening@nexgo.de>.
176 2004-05-10 Paul D. Smith <psmith@gnu.org>
178 * remake.c (update_file): Don't walk the double-colon chain unless
179 this is a double-colon rule. Fix suggested by Boris Kolpackov
180 <boris@kolpackov.net>.
182 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
183 * readme.vms: New section describing OpenVMS support and issues.
184 * default.c (default_variables): Add support for IA64.
185 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
186 without some privilege aborts make with the error
187 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
188 pressing Ctrl+Y and the input device is no terminal. The change
189 catches this error and just continues.
191 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
193 2004-04-25 Paul D. Smith <psmith@gnu.org>
195 * commands.c (set_file_variables): Set $< properly in the face of
196 order-only prerequisites.
197 Patch from Boris Kolpackov <boris@kolpackov.net>
199 2004-04-21 Bob Byrnes <byrnes@curl.com>
201 * main.c (main): Notice failures to remake makefiles.
203 2004-03-28 Paul D. Smith <psmith@gnu.org>
205 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
207 * job.c: No default shell for RISC OS.
208 (load_too_high): Hard-code the return to 1.
209 (construct_command_argv_internal): No sh_chars or sh_cmds.
210 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
212 2004-03-20 Paul D. Smith <psmith@gnu.org>
214 * variable.c (do_variable_definition): Don't append from the
215 global set if a previous non-appending target-specific variable
216 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
219 * expand.c (reference_variable): Don't give up on variables with
220 no value that have the target-specific append flag set: they might
221 have a value after all. Reported by Oliver Schmidt
222 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
223 <nikulin@dx1cmd.inp.nsk.su>.
225 * rule.c (count_implicit_rule_limits): Don't delete patterns which
226 refer to absolute pathnames in directories that don't exist: some
227 portion of the makefile could create those directories before we
228 match the pattern. Fixes bugs #775 and #108.
230 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
232 * main.c (main): Free makefile_mtimes if we have any.
233 * README.W32.template: Update documentation for the current status
234 of the MS-Windows port.
235 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
236 environment variable is sometimes already defined which causes the
238 * main.c (debug_signal_handler): Only define this function if
239 SIGUSR1 is available.
241 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
243 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
244 * README.OS2.template: Documentation updates.
245 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
246 link line for safety.
247 * maintMakefile (build.sh.in): Remove an extraneous ")".
248 * job.c (child_execute_job): Close saved FDs.
249 * job.c (exec_command) [OS/2]: exec_command(): If the command
250 can't be exec'ed and if the shell is not Unix-sh, then try again
251 with argv = { "cmd", "/c", ... }. Normally, this code is never
252 reached for the cmd shell unless the command really doesn't exist.
253 (construct_command_argv_internal) [OS/2]: The code for cmd
254 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
255 The CMD builtin commands are case insensitive so use strcasecmp().
257 2004-03-19 Paul D. Smith <psmith@gnu.org>
259 * read.c (do_define): Re-order line counter increment so the count
260 is accurate (we were losing one line per define). Reported by
261 Dave Yost <Dave@Yost.com>.
263 2004-03-06 Paul D. Smith <psmith@gnu.org>
265 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
267 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
268 * misc.c (message,error,fatal): Ditto.
269 * configh.dos.template: Define HAVE_ANSI_COMPILER.
270 * config.h.W32.template: Ditto.
271 * config.h-vms.template: Ditto.
272 * config.ami.template: Ditto.
274 2004-03-04 Paul D. Smith <psmith@gnu.org>
276 * README.template: Add a note about broken /bin/sh on SunOS
277 4.1.3_U1 & 4.1.4. Fix up Savannah links.
279 * misc.c (message, error, fatal): Don't use "..." if we're using
280 varargs. ansi2knr should handle this but it doesn't work: it
281 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
282 done. On many systems (SunOS for example) va_dcl is a #define.
283 So, force the use of the non-"..." version on pre-ANSI compilers.
285 * maintMakefile (sign-dist): Create some rules to help automate
286 the new GNU ftp upload method.
288 2004-02-24 Paul D. Smith <psmith@gnu.org>
290 * config.h.W32.template: Add HAVE_STDARG_H
291 * config.h-vms.template: Ditto.
292 * config.ami.template: Ditto.
294 2004-02-23 Jonathan Grant <jg-make@jguk.org>
296 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
297 * build_w32.bat: Remove extra "+".
299 2004-02-23 Paul D. Smith <psmith@gnu.org>
301 * make.h: Create an UNUSED macro to mark unused parameters.
302 * (many): Clean up warnings by applying UNUSED, fixing
303 signed/unsigned incompatibilities, etc.
305 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
307 * filedef.h: Name the command_state enumeration.
308 * file.c (set_command_state): Use the enumeration in the function
311 * configure.in: Explicitly set SET_MAKE to empty, to disable
312 MAKE=make even when no make already exists. Fix bug #3823.
314 2004-02-22 Paul D. Smith <psmith@gnu.org>
316 * maintMakefile: Perl script to clean up all non-CVS files. Use
317 it on all the subdirectories for the cvs-clean target.
319 * main.c (decode_switches): Require non-empty strings for all our
320 string command-line options. Fixes Debian bug # 164165.
322 * configure.in: Check for stdarg.h and varargs.h.
323 * make.h (USE_VARIADIC): Set this if we can use variadic functions
324 for printing messages.
325 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
330 A number of patches for OS/2 support from Andreas Buening
331 <andreas.buening@nexgo.de>:
333 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
334 disable the SIGCHLD handler.
335 (reap_children) [OS/2]: Remove special handling of job_rfd.
336 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
337 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
338 * main.c (main) [OS/2]: Special handling for paths in OS/2.
339 * configure.in [OS/2]: Force SA_RESTART for OS/2.
340 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
343 2004-02-21 Paul D. Smith <psmith@gnu.org>
345 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
346 <mail@kristov.de> reports that if process_begin() fails we don't
347 handle the error condition correctly in all cases.
348 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
349 to have a newline on the message.
351 * job.c (construct_command_argv_internal): Add "test" to UNIX
352 sh_cmds[]. Fixes Savannah bug # 7606.
354 2004-02-04 Paul D. Smith <psmith@gnu.org>
356 * job.c (vms_handle_apos) [VMS]: Fix various string handling
357 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
358 Hartmut Becker <Hartmut.Becker@hp.com>.
360 2004-01-21 Paul D. Smith <psmith@gnu.org>
362 * job.c (load_too_high): Implement an algorithm to control the
363 "thundering herd" problem when using -l to control job creation
364 via the load average. The system only recomputes the load once a
365 second but we can start many jobs in a second. To solve this we
366 keep track of the number of jobs started in the last second and
367 apply a weight to try to guess what a correct load would be.
368 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
369 Also fixes bug #4693.
370 (reap_children): Decrease the job count for this second.
371 (start_job_command): Increase the job count for this second.
373 * read.c (conditional_line): Expand the text after ifn?def before
374 checking to see if it's a single word. Fixes bug #7257.
376 2004-01-09 Paul D. Smith <psmith@gnu.org>
378 * file.c (print_file): Recurse to print all targets in
379 double-colon rules. Fixes bug #4518, reported (with patch) by
380 Andrew Chatham <chatham@google.com>.
382 2004-01-07 Paul D. Smith <psmith@gnu.org>
384 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
385 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
386 AC_FUNC_SETVBUF_REVERSED.
388 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
389 (MAKE Variable): Fix Savannah bug #4898.
391 * job.c (construct_command_argv_internal): Add "!" to the list of
392 shell escape chars. POSIX sh allows it to appear before a
393 command, to negate the exit code. Fixes bug #6404.
395 * implicit.c (pattern_search): When matching an implicit rule,
396 remember which dependencies have the ignore_mtime flag set.
397 Original fix provided in Savannah patch #2349, by Benoit
398 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
400 2003-11-22 Paul D. Smith <psmith@gnu.org>
402 * README.W32.template (Outputs): Clarification on -j with
403 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
406 2003-11-02 Paul D. Smith <psmith@gnu.org>
408 * function.c (func_if): Strip all the trailing whitespace from the
409 condition, then don't expand it. Fixed bug # 5798.
411 * expand.c (recursively_expand_for_file): If we're expanding a
412 variable with no file context, then use the variable's context.
415 2003-10-21 Paul D. Smith <psmith@gnu.org>
417 * main.c (log_working_directory): Add newlines to printf()s.
419 * README.cvs: Add a note to ignore warnings during autoreconf.
421 * maintMakefile (po_repo): Set a new URL for PO file updates.
422 (get-config/config.guess get-config/config.sub): Get these files
423 from the Savannah config project instead of ftp.gnu.org.
425 2003-10-05 Paul Eggert <eggert@twinsun.com>
427 * main.c (main): Avoid potential subscript error if environ has
430 2003-08-22 Paul D. Smith <psmith@gnu.org>
432 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
433 systems which don't yet implement the C89 standard :-/.
435 2003-07-18 Paul D. Smith <psmith@gnu.org>
437 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
438 [WINDOWS32]: Initialize hash.
440 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
442 * dir.c (read_dirstream): Provide a workaround for broken versions of
443 the MinGW dirent structure.
445 2003-05-30 Earnie Boyd <earnie@users.sf.net>
447 * w32/include/dirent.h: Add __MINGW32__ filter.
449 2003-05-30 Earnie Boyd <earnie@users.sf.net>
451 * make.h: Add global declaration of *make_host.
452 * main.c (print_usage): Remove local declaration of *make_host.
453 (print_version): Display "This program built for ..." after Copyright
456 2003-05-30 Earnie Boyd <earnie@users.sf.net>
458 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
459 execution of "makeinfo --html make.texi".
461 2003-04-30 Paul D. Smith <psmith@gnu.org>
463 * build.template: Make some changes to maybe allow this script to
464 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
466 * README.OS2.template: New file for OS/2 support. Original
467 contributed by Andreas Buening.
468 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
471 2003-04-19 Paul D. Smith <psmith@gnu.org>
473 Fix bug #1405: allow a target to match multiple pattern-specific
476 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
477 variable.c, where they've always belonged.
478 * rule.h: Move the prototypes and struct pattern_var as well.
479 * variable.c (initialize_file_variables): Invoke
480 lookup_pattern_var() in a loop, until no more matches are found.
481 If a match is found, create a new variable set for the target's
482 pattern variables. Then merge the contents of each matching
483 pattern variable set into the target's pattern variable set.
484 (lookup_pattern_var): Change this function to be usable
485 in a loop. It takes a starting position: if NULL, start at the
486 beginning; if non-NULL, start with the pattern variable after that
487 position, and return the next matching pattern.
488 (create_pattern_var): Create a unique instance of
489 pattern-specific variables for every definition in the makefile.
490 Don't combine the same pattern together. This allows us to
491 process the variable handling properly even when the same pattern
492 is used multiple times.
493 (parse_variable_definition): New function: break out the parsing
494 of a variable definition line from try_variable_definition.
495 (try_variable_definition): Call parse_variable_definition to
497 (print_variable_data_base): Print out pattern-specific variables.
498 * variable.h (struct variable): Remember when a variable is
499 conditional. Also remember its flavor.
500 (struct pattern_var): Instead of keeping a variable set, we just
501 keep a single variable for each pattern.
502 * read.c (record_target_var): Each pattern variable contains only a
503 single variable, not a set, so create it properly.
504 * doc/make.texi (Pattern-specific): Document the new behavior.
506 2003-04-17 Paul D. Smith <psmith@gnu.org>
508 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
509 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
510 file/directory naming rules for VMS so I can't tell whether this
513 2003-04-09 Paul D. Smith <psmith@gnu.org>
515 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
516 DOS-style pathnames: backslash separators and drive specifiers.
518 2003-03-28 Paul D. Smith <psmith@gnu.org>
520 * file.c (snap_deps): If .SECONDARY with no targets is given, set
521 the intermediate flag on all targets. Fixes bug #2515.
523 2003-03-24 Paul D. Smith <psmith@gnu.org>
525 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
526 Upgrade to autoconf 2.57 and automake 1.7.3.
528 * job.c: More OS/2 changes from Andreas Buening.
530 * file.c (print_file): Fix variable initialization.
533 * remake.c (notice_finished_file):
535 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
536 some calls (like readdir()) return NULL in valid situations
537 without resetting errno. Fixes bug #2846.
539 2003-02-25 Paul D. Smith <psmith@gnu.org>
541 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
543 * job.c (_is_unixy_shell) [OS/2]: New function.
544 Set default shell to /bin/sh.
545 (reap_children): Close the job_rfd pipe here since we don't use a
547 (set_child_handler_action_flags): define this to empty on OS/2.
548 (start_job_command): Close the jobserver pipe and use
549 child_execute_job() instead of fork/exec.
550 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
551 rather than exec'ing, then reconfigure stdin/stdout.
552 (exec_command): Rewrite to use spawn instead of exec. Return the
555 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
556 in DOS. Handle the TEMP environment variable as in DOS. Don't
557 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
558 use -j in DOS mode. Use child_execute_job() instead of
561 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
564 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
565 prototypes that return values.
567 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
569 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
570 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
572 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
575 2003-02-24 Paul D. Smith <psmith@gnu.org>
577 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
578 * job.c (child_execute_job) [VMS]: New code for handling spawn().
579 (child_execute_job) [VMS]: Handle error status properly.
580 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
582 * function.c (func_shell): Use EINTRLOOP() while reading from the
583 subshell pipe (Fixes bug #2502).
584 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
586 * main.c (main): Ditto.
588 2003-01-30 Paul D. Smith <psmith@gnu.org>
590 * read.c (eval): eval() was not fully reentrant, because the
591 collapsed buffer was static. Change it to be an automatic
592 variable so that eval() can be invoked recursively.
594 (eval): Apply patch # 1022: fix memory reference error on long
595 target-specific variable lines.
596 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
598 * function.c (check_numeric): Combine the is_numeric() function
599 into this function, since it's only called from one place.
600 Constify this function. Have it print the incorrect string in the
601 error message. Fixes bug #2407.
602 (strip_whitespace): Constify.
604 * expand.c (expand_argument): Constify.
606 2003-01-29 Paul D. Smith <psmith@gnu.org>
608 Fix bug # 2169, also reported by other people on various systems.
610 * make.h: Some systems, such as Solaris and PTX, do not fully
611 implement POSIX-compliant SA_RESTART functionality; important
612 system calls like stat() and readdir() can still fail with EINTR
613 even if SA_RESTART has been set on the signal handler. So,
614 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
615 EINTR for system calls which return -1 or 0 (NULL), respectively,
617 Also, remove the old atomic_stat()/atomic_readdir() and
618 HAVE_BROKEN_RESTART handling.
620 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
622 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
623 * remake.c (touch_file): Ditto.
625 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
626 * read.c (construct_include_path): Ditto.
627 * remake.c (name_mtime): Ditto.
628 * vpath.c (selective_vpath_search): Ditto.
629 * dir.c (find_directory): Ditto.
631 (find_directory): Use ENULLLOOP() to wrap opendir().
632 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
634 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
635 atomic_readdir() handling.
637 2003-01-22 Paul D. Smith <psmith@gnu.org>
639 * function.c (func_call): Fix Bug #1744. If we're inside a
640 recursive invocation of $(call ...), mask any of the outer
641 invocation's arguments that aren't used by this one, so that this
642 invocation doesn't "inherit" them accidentally.
644 2002-12-05 Paul D. Smith <psmith@gnu.org>
646 * function.c (subst_expand): Valery Khamenia reported a
647 pathological performance hit when doing substitutions on very
648 large values with lots of words: turns out we were invoking
649 strlen() a ridiculous number of times. Instead of having each
650 call to sindex() call strlen() again, keep track of how much of
651 the text we've seen and pass the length to sindex().
653 2002-11-19 Paul D. Smith <psmith@gnu.org>
655 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
658 2002-11-16 Paul D. Smith <psmith@gnu.org>
660 * NMakefile.template (OBJS): Add hash.c object file.
661 * SMakefile.template (srcs): Ditto.
662 * Makefile.ami (objs): Ditto.
663 * build_w32.bat: Ditto.
665 * Makefile.DOS.template: Remove extra dependencies.
667 2002-10-25 Paul D. Smith <psmith@gnu.org>
669 * expand.c (install_variable_buffer): New function. Install a new
670 variable_buffer context and return the previous one.
671 (restore_variable_buffer): New function. Free the current
672 variable_buffer context and put a previously saved one back.
673 * variable.h: Prototypes for {install,restore}_variable_buffer.
674 * function.c (func_eval): Push a new variable_buffer context
675 before we eval, then restore the old one when we're done.
678 * read.c (install_conditionals): New function. Install a new
679 conditional context and return the previous one.
680 (restore_conditionals): New function. Free the current
681 conditional context and put a previously saved one back.
682 (eval): Use the {install,restore}_conditionals for "include"
684 (eval_buffer): Use {install,restore}_conditionals to preserve the
685 present conditional state before we evaluate the buffer.
688 * doc/make.texi (Quick Reference): Add references to $(eval ...)
690 (Recursion): Add a variable index entry for CURDIR.
692 * README.cvs: Update to appropriate versions.
693 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
694 don't need to copy loadavg.c: automake is smart enough to create
695 it for me. Still have a bug in automake related to ansi2knr tho.
697 2002-10-14 Paul D. Smith <psmith@gnu.org>
699 * remake.c (notice_finished_file): Only touch targets if they have
700 at least one command (as per POSIX). Resolve Bug #1418.
702 * *.c: Convert to using ANSI C-style function definitions.
703 * Makefile.am: Enable the ansi2knr feature of automake.
704 * configure.in: ditto.
706 2002-10-13 Paul D. Smith <psmith@gnu.org>
708 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
709 for automatic variable values like $^, etc. In the case of very
710 large lists of prerequisites this causes problems. Instead reuse
711 a static buffer (resizeable) for each variable.
713 * read.c (eval): Fix Bug #1391: allow "export" keyword in
714 target-specific variable definitions. Check for it and set an
716 (record_target_var): Set the export field to v_export if the
717 "exported" flag is set.
718 * doc/make.texi (Target-specific): Document the ability to use
721 * doc/make.texi: Change the name of the section on automatic
722 variables from "Automatic" to "Automatic Variables". Added text
723 clarifying the scope of automatic variables.
725 2002-10-04 Paul D. Smith <psmith@gnu.org>
727 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
729 (record_files): Ditto.
731 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
732 the search for the '=' to only within the enclosing parens.
734 2002-10-03 Paul D. Smith <psmith@gnu.org>
736 Version 3.80 released.
738 * dir.c: Change hash functions to use K&R function definition style.
743 Update to automake 1.7.
745 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
746 (pdf): Remove this target as automake now provides one.
748 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
750 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
752 * makefile.com: Updates for GNU make 3.80.
753 * makefile.vms: Ditto.
755 2002-09-23 Paul D. Smith <psmith@gnu.org>
757 * read.c (enum make_word_type): Remove w_comment.
758 (get_next_mword): Don't treat comment characters as special; where
759 this function is used we will never see a comment (it's stripped
760 before we get here) and treating comments specially means that
761 targets like "foo\#bar" aren't handled properly.
763 2002-09-18 Paul D. Smith <psmith@gnu.org>
765 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
767 * read.c (eval): Expansion of arguments to export/unexport was
768 ignoring all arguments after the first one. Change the algorithm
769 to expand the whole line once, then parse the results.
771 2002-09-17 Paul D. Smith <psmith@gnu.org>
773 Fix Bug #940 (plus another bug I found while looking at this):
775 * read.c (record_target_var): enter_file() will add a new entry if
776 it's a double-colon target: we don't want to do that in this
777 situation. Invoke lookup_file() and only enter_file() if it does
778 not already exist. If the file we get back is a double-colon then
779 add this variable to the "root" double-colon target.
781 * variable.c (initialize_file_variables): If this file is a
782 double-colon target but is not the "root" target, then initialize
783 the root and make the root's variable list the parent of our
786 2002-09-13 Paul D. Smith <psmith@gnu.org>
788 * doc/make.texi (MAKE Variable): Add some indexing for "+".
790 * hash.c (round_up_2): Get rid of a warning.
792 2002-09-12 Paul D. Smith <psmith@gnu.org>
794 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
795 so it doesn't complain about getloadavg.c.
797 * commands.c (set_file_variables): Make sure we always alloca() at
798 least 1 character for the value of $? (for '\0').
800 2002-09-11 Paul D. Smith <psmith@gnu.org>
802 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
803 macro to use RESULT instead of the incorrect _RESULT_.
805 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
806 and atomic_readdir(). We need to #include dirent.h to get this to
808 * misc.c (atomic_readdir): Fix typos.
810 2002-09-10 Paul D. Smith <psmith@gnu.org>
812 * read.c (eval): Expand variable lists given to export and
813 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
814 (conditional_line): Ditto for "ifdef". Fixes bug #103.
816 * doc/make.texi (Variables/Recursion): Document this.
817 (Conditional Syntax): And here.
819 2002-09-09 Paul D. Smith <psmith@gnu.org>
821 * configure.in: Check for memmove().
823 2002-09-07 Paul D. Smith <psmith@gnu.org>
825 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
826 Michael Sterrett <msterret@coat.com> reports that while it has
827 SA_RESTART, it does not work properly.
829 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
830 that invokes stat() and loops to do it again if it returns EINTR.
831 (atomic_readdir): Ditto, with readdir().
833 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
834 and readdir() to atomic_stat() and atomic_readdir().
836 2002-09-04 Paul D. Smith <psmith@gnu.org>
838 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
839 reports that GNU make sometimes doesn't recognize that targets can
840 be made, when directories can be created as prerequisites. He
841 reports that changing the order of predicates in the DEP->changed
842 flag test so that lookup_file() is always performed, solves this
845 2002-08-08 Paul D. Smith <psmith@gnu.org>
847 * configure.in: Require a newer version of gettext.
849 * misc.c (perror_with_name): Translate the format string (for
850 right-to-left language support).
851 (pfatal_with_name): Ditto.
853 * main.c: Create a static array of strings to store the usage
854 text. This is done to facilitate translations.
855 (struct command_switch): Remove argdesc and description fields.
856 (switches): Remove values for obsolete fields.
857 (print_usage): Print each element of the usage array.
859 * hash.c: Change function definitions to be K&R style.
861 2002-08-02 Paul D. Smith <psmith@gnu.org>
863 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
864 this one because it's too hard to get right. We'll look at it for
866 * main.c (main): Don't create the .TARGETS variable.
867 * variable.c (handle_special_var): Don't handle .TARGETS.
869 2002-08-01 Paul D. Smith <psmith@gnu.org>
871 * main.c (switches): Add a new option, -B (--always-make). If
872 specified, make will rebuild all targets that it encounters even
873 if they don't appear to be out of date.
874 (always_make_flag): New flag.
875 * make.h: Extern always_make_flag.
876 * remake.c (update_file_1): Check always_make_flag; if it's set we
877 will always rebuild any target we can, even if none of its
878 prerequisites are newer.
881 * doc/make.texi (Shell Function): Make it clear that make
882 variables marked as "export" are not passed to instances of the
885 Add new introspection variable .VARIABLES and .TARGETS.
887 * variable.c (handle_special_var): New function. If the variable
888 reference passed in is "special" (.VARIABLES or .TARGETS),
889 calculate the new value if necessary. .VARIABLES is handled here:
890 walk through the hash of defined variables and construct a value
891 which is a list of the names. .TARGETS is handled by
893 (lookup_variable): Invoke handle_special_var().
894 * file.c (build_target_list): Walk through the hask of known files
895 and construct a list of the names of all the ones marked as
897 * main.c (main): Initialize them to empty (and as simple variables).
898 * doc/make.texi (Special Variables): Document them.
899 * NEWS: Mention them.
901 * variable.h (struct variable): Add a new flag "exportable" which
902 is true if the variable name is valid for export.
903 * variable.c (define_variable_in_set): Set "exportable" when a new
905 (target_environment): Use the "exportable" flag instead of
906 re-checking the name here... an efficiency improvement.
908 2002-07-31 Paul D. Smith <psmith@gnu.org>
910 * config.h-vms.template: Updates to build on VMS. Thanks to
911 Brian_Benning@aksteel.com for helping verify the build.
912 * makefile.com: Build the new hash.c file.
913 * hash.h: Use strcpmi(), not stricmp(), in the
914 HAVE_CASE_INSENSITIVE_FS case.
916 2002-07-30 Paul D. Smith <psmith@gnu.org>
918 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
919 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
920 Reported by <Brian_Benning@aksteel.com>.
922 2002-07-10 Paul D. Smith <psmith@gnu.org>
924 * variable.c (pop_variable_scope): Remove variable made unused by
925 new hash infrastructure.
926 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
927 comparisons as well as name comparisons.
928 * variable.h: Add a prototype for new hash_init_function_table().
929 * file.c (lookup_file): Remove variables made unused by new hash
931 * dir.c (directory_contents_hash_2): Missing return of hash value.
932 (dir_contents_file_exists_p): Remove variables made unused by new
936 Installed Greg McGary's integration of the hash functions from the
937 GNU id-utils package:
939 2002-07-10 Greg McGary <greg@mcgary.org>
941 * scripts/functions/filter-out: Add literals to to the
942 pattern space in order to add complexity, and trigger
943 use of an internal hash table. Fix documentation strings.
944 * scripts/targets/INTERMEDIATE: Reverse order of files
945 passed to expected `rm' command.
947 2002-07-10 Greg McGary <greg@mcgary.org>

1039 2002-07-10 Paul D. Smith <psmith@gnu.org>
1041 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
1042 prerequisite list. A real SysV make will expand the entire
1043 prerequisites list _twice_: we don't do that as it's a big
1044 backward-compatibility problem. We only replace those specific
1047 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
1048 references left in the list of prerequisites. Check for .POSIX as
1049 we record targets, so we can disable non-POSIX behavior while
1050 reading makefiles as well as running them.
1051 (eval): Check the prerequisite list to see if we have anything
1052 that looks like a SysV prerequisite variable reference.
1054 2002-07-09 Paul D. Smith <psmith@gnu.org>
1056 * doc/make.texi (Prerequisite Types): Add a new section describing
1057 order-only prerequisites.
1059 * read.c (uniquize_deps): If we have the same file as both a
1060 normal and order-only prereq, get rid of the order-only prereq,
1061 since the normal one supersedes it.
1063 2002-07-08 Paul D. Smith <psmith@gnu.org>
1065 * AUTHORS: Added Greg McGary to the AUTHORS file.
1066 * NEWS: Blurbed order-only prerequisites.
1067 * file.c (print_file): Show order-only deps properly when printing
1070 * maintMakefile: Add "update" targets for wget'ing the latest
1071 versions of various external files. Taken from Makefile.maint in
1074 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
1075 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
1077 2002-07-07 Paul D. Smith <psmith@gnu.org>
1079 * po/*.po: Remove. We'll use wget to retrieve them at release
1082 * variable.c (do_variable_definition) [W32]: On W32 using cmd
1083 rather than a shell you get an exception. Make sure we look up
1084 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
1086 * remake.c (notice_finished_file): Fix handling of -t flag.
1087 Patch provided by Henning Makholm <henning@makholm.net>.
1089 * implicit.c (pattern_search): Some systems apparently run short
1090 of stack space, and using alloca() in this function caused an
1091 overrun. I modified it to use xmalloc() on the two variables
1092 which seemed like they might get large. Fixes Bug #476.
1094 * main.c (print_version): Update copyright notice to conform with
1096 (print_usage): Update help output.
1098 * function.c (func_eval): Create a new make function, $(eval
1099 ...). Expand the arguments, put them into a buffer, then invoke
1100 eval_buffer() on the resulting string.
1101 (func_quote): Create a new function, $(quote VARNAME). Inserts
1102 the value of the variable VARNAME without expanding it any
1105 * read.c (struct ebuffer): Change the linebuffer structure to an
1106 "eval buffer", which can be either a file or a buffer.
1107 (eval_makefile): Move the code in the old read_makefile() which
1108 located a makefile into here: create a struct ebuffer with that
1109 information. Have it invoke the new function eval() with that
1111 (eval_buffer): Create a new function that creates a struct ebuffer
1112 that holds a string buffer instead of a file. Have it invoke
1113 eval() with that ebuffer.
1114 (eval): New function that contains the guts of the old
1115 read_makefile() function: this function parses makefiles. Obtains
1116 data to parse from the provided ebuffer. Some modifications to
1117 make the flow of the function cleaner and clearer. Still could
1118 use some work here...
1119 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
1120 contents of the define/endef variable from the ebuffer.
1121 (readstring): Read the next line from a string-style ebuffer.
1122 (readline): Read the next line from an ebuffer. If it's a string
1123 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
1126 * dep.h (eval_buffer): Prototype eval_buffer();
1128 * variable.c (do_variable_definition): Make sure that all
1129 non-target-specific variables are registered in the global set.
1130 If we're invoked from an $(eval ...) we might be inside a $(call
1131 ...) or other function which has pushed a variable scope; we still
1132 want to define our variables from evaluated makefile code in the
1135 2002-07-03 Greg McGary <greg@mcgary.org>
1137 * dep.h (struct dep) [ignore_mtime]: New member.
1138 [changed]: convert to a bitfield.
1139 * implicit.c (pattern_search): Zero ignore_mtime.
1140 * main.c (main, handle_non_switch_argument): Likewise.
1141 * rule.c (convert_suffix_rule): Likewise.
1142 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
1143 (read_makefile): Parse '|' in prerequisite list.
1144 (uniquize_deps): Consider ignore_mtime when comparing deps.
1145 * remake.c (update_file_1, check_dep): Don't force remake for
1146 dependencies that have d->ignore_mtime.
1147 * commands.c (FILE_LIST_SEPARATOR): New constant.
1148 (set_file_variables): Don't include a
1149 prerequisite in $+, $^ or $? if d->ignore_mtime.
1152 2002-06-18 Paul D. Smith <psmith@gnu.org>
1154 * make.texinfo: Updates for next revision. New date/rev/etc.
1155 Recreate all Info menus. Change license on the manual to the GNU
1156 Free Documentation License. A number of typos.
1157 (Variables Simplify): Don't use "-" before it's defined.
1158 (Automatic Prerequisites): Rewrite the target example to work
1159 properly if the compile fails. Remove incorrect comments about
1160 how "set -e" behaves.
1161 (Text Functions): Move the "word", "wordlist", "words", and
1162 "firstword" functions here, from "File Name Functions".
1163 * make-stds.texi: Update from latest GNU version.
1164 * fdl.texi: (created) Import the latest GNU version.
1166 2002-06-06 Paul D. Smith <psmith@gnu.org>
1168 * variable.c (do_variable_definition): New function: extract the
1169 part of try_variable_definition() that actually sets the value
1170 into a separate function.
1171 (try_variable_definition): Call do_variable_definition() after
1172 parsing the variable definition string.
1173 (define_variable_in_set): Make the name argument const.
1175 * variable.h (enum variable_flavor): Make public.
1176 (do_variable_definition): Create prototype.
1178 * read.c (read_all_makefiles): Create a new built-in variable,
1180 (read_makefile): Add each makefile read in to this variable value.
1182 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
1184 * Makefile.DOS.template: Tweak according to changes in the
1185 distribution. Add back the dependencies of *.o files.
1187 * configh.dos.template: Synchronize with config.h.in.
1189 2002-05-09 Paul D. Smith <psmith@gnu.org>
1191 * file.c (file_timestamp_now): Use K&R function declaration.
1193 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
1194 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
1195 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
1196 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
1197 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
1198 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
1199 nlist.n_name is a pointer rather than an array.
1201 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
1202 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
1203 * configure.in: Use it instead of the old version.
1205 * main.c (main): Prefer setvbuf() to setlinebuf().
1207 2002-05-08 Paul D. Smith <psmith@gnu.org>
1209 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
1210 (loadavg_LDADD): Ditto.
1212 2002-04-29 Paul D. Smith <psmith@gnu.org>
1214 * expand.c (recursively_expand_for_file): Rename
1215 recursively_expand() to recursively_expand_for_file() and provide
1216 an extra argument, struct file. If the argument is provided, set
1217 the variable scope to that of the file before expanding.
1218 * variable.h (recursively_expand): Make this a macro that invokes
1219 recursively_expand_for_file() with a NULL file pointer.
1220 * variable.c (target_environment): Call the renamed function and
1221 provide the current file context.
1222 Fixes Debian bug #144306.
1224 2002-04-28 Paul D. Smith <psmith@gnu.org>
1226 Allow $(call ...) user-defined variables to be self-referencing
1227 without throwing an error. Allows implementation of transitive
1228 closures, among other possibly useful things.
1229 Requested by: Philip Guenther <guenther@sendmail.com>
1231 * variable.h (struct variable): Add a new field: exp_count, and
1232 new macros to hold its size and maximum value.
1233 (warn_undefined): Make this a macro.
1234 * variable.c (define_variable_in_set): Initialize it.
1235 * expand.c (recursively_expand): If we detect recursive expansion
1236 of a variable, check the exp_count field. If it's greater than 0
1237 allow the recursion and decrement the count.
1238 (warn_undefined): Remove this (now a macro in variable.h).
1239 * function.c (func_call): Before we expand the user-defined
1240 function, modify its exp_count field to contain the maximum
1241 number of recursive calls we'll allow. After the call, reset it
1244 2002-04-21 Paul D. Smith <psmith@gnu.org>
1246 Modified to use latest autoconf (2.53), automake (1.6.1), and
1247 gettext (0.11.1). We're using gettext's new "external" support,
1248 to avoid including libintl source with GNU make.
1250 * README.cvs: New file. Explain how to build GNU make from CVS.
1252 * configure.in: Modify checking for the system glob library.
1253 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
1254 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
1255 etc. will manage it correctly). Set an automake conditional
1256 USE_LOCAL_GLOB to decide whether to compile the glob library.
1258 * getloadavg.c (main): Include make.h in the "TEST" program to
1261 * Makefile.am: Remove special rules for loadavg. Replace them
1262 with Automake capabilities for building extra programs.
1264 * signame.c: This file does nothing if the system provide
1265 strsignal(). If not, it implements strsignal(). If the system
1266 doesn't define sys_siglist, then we make our own; otherwise we use
1268 * signame.h: Removed.
1270 * main.c (main): No need to invoke signame_init(). Update copyright.
1272 * ABOUT-NLS: Removed.
1273 * gettext.c: Removed.
1274 * gettext.h: Get a simplified copy from the gettext package.
1276 * i18n/*.po: Moved to po/.
1279 * config/*: Created. Contains package configuration helper files.
1280 * config.guess, config.sub: Moved to config directory.
1282 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
1283 Rework to use new-style autoconf features. Use the "external"
1284 mode for gettext. Make the build.sh config file conditional on
1285 whether build.sh.in exists, to avoid autoconf errors.
1286 * acinclude.m4: Removed almost all macros as being obsolete.
1287 Rewrote remaining macros to use AC_DEFINE.
1288 * acconfig.h: Removed.
1290 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
1291 conditional to handle customs support. Remove special handling
1294 2002-04-20 Paul D. Smith <psmith@gnu.org>
1296 * function.c (func_call): Don't mark the argument variables $1,
1297 etc. as recursive. They've already been fully expanded so
1298 there's no need to do it again, and doing so strips escaped $'s.
1299 Reported by Sebastian Glita <glseba@yahoo.com>.
1301 * remake.c (notice_finished_file): Walk through double-colon
1302 entries via the prev field, not the next field!
1303 Reported by Greg McGary <greg@mcgary.org>.
1305 * main.c (main): If the user specifies -q and asks for a specific
1306 target which is a makefile, we got an assert. In that case it
1307 turns out we should continue normally instead.
1309 * i18n/de.po, i18n/fr.po: Installed an updated translation.
1311 * i18n/he.po: Installed a new translation.
1313 2002-01-07 Paul D. Smith <psmith@gnu.org>
1315 * i18n/es.po, i18n/ru.po: Installed an updated translation.

1319 * i18n/ja.po: Installed an updated translation.
1321 2001-09-04 Paul D. Smith <psmith@gnu.org>
1323 * i18n/da.po: Installed an updated translation.
1325 2001-08-03 Paul D. Smith <psmith@gnu.org>
1327 * i18n/fr.po: Installed an updated translation.
1328 Resolves Debian bug #106720.
1330 2001-06-13 Paul D. Smith <psmith@gnu.org>
1332 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
1335 2001-06-11 Paul D. Smith <psmith@gnu.org>
1337 * i18n/ko.po: Installed a new translation.
1339 2001-05-06 Paul D. Smith <psmith@gnu.org>
1341 Modify the EINTR handling.
1343 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
1344 the way in which we manage the file descriptor/signal handler race
1345 trap to be more efficient.
1347 2001-05-06 Paul Eggert <eggert@twinsun.com>
1349 Restart almost all system calls that are interrupted, instead
1350 of worrying about EINTR. The lone exception is the read() for
1353 * configure.in (HAVE_SA_RESTART): New macro.
1354 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
1355 * main.c (main): Use SA_RESTART instead of the old,
1356 nonstandard SA_INTERRUPT.
1358 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
1359 * main.c (bsd_signal): New function or macro,
1360 if the implementation doesn't supply it.
1361 (The bsd_signal function will be in POSIX 1003.1-200x.)
1362 (HANDLESIG): Remove.
1363 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
1365 * make.h (EINTR_SET): Remove.
1366 (SA_RESTART): New macro.
1368 * arscan.c (ar_member_touch): Don't worry about EINTR.
1369 * function.c (func_shell): Likewise.
1370 * job.c (reap_children, free_child, new_job): Likewise.
1371 * main.c (main): Likewise.
1372 * remake.c (touch_file, name_mtime): Likewise.
1374 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
1375 if fstat failed with errno!=EINTR, the error was ignored.
1377 * job.c (set_child_handler_action_flags): New function.
1378 (new_job): Use it to temporarily clear the SIGCHLD action flags
1379 while reading the token.
1381 2001-05-02 Paul D. Smith <psmith@gnu.org>
1383 * job.c (start_job_command): Don't add define/endef per-line flags
1384 to the top-level flags setting.
1386 2001-04-03 Paul D. Smith <psmith@gnu.org>
1388 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
1389 bit on error, so check for odd return values, not non-0 return
1391 (VMS_get_member_info): Calculate the timezone differences correctly.
1392 Reported by John Fowler <jfowler@nyx.net>.
1395 2001-03-14 Paul D. Smith <psmith@gnu.org>
1397 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
1398 value before invoking define_variable().
1399 Reported by John Fowler <jfowler@nyx.net>.
1401 2001-02-07 Paul D. Smith <psmith@gnu.org>
1403 * read.c (record_target_var): If we reset the variable due to a
1404 command-line variable setting overriding it, turn off the "append"
1407 2001-01-17 Paul D. Smith <psmith@gnu.org>
1409 * variable.c (lookup_variable) [VMS]: When getting values from the
1410 environment, allocate enough space for the _value_ plus escapes,
1411 not enough space for the name plus escapes :-/.
1412 Reported by John Fowler <jfowler@nyx.net>.
1414 * remake.c (f_mtime): Removed the "***" prefix from the mod time
1415 warnings that make generates, so it doesn't look like an error.
1416 Reported by Karl Berry <karl@gnu.org>.
1419 Fix for PR/2020: Rework appended target-specific variables. I'm
1420 fairly confident this algorithm is finally correct.
1422 * expand.c (allocated_variable_append): Rewrite. Instead of
1423 expanding each appended variable then adding all the expanded
1424 strings together, we append all the unexpanded values going up
1425 through the variable set contexts, then expand the final result.
1426 This behaves just like non-target-specific appended variable
1427 values, while the old way didn't in various corner cases.
1428 (variable_append): New function: recursively append the unexpanded
1429 value of a variable, walking from the outermost variable scope to
1431 * variable.c (lookup_variable): Remove the code that looked up the
1432 variable set list if the found variable was "append". We don't
1434 (lookup_variable_in_set): Make this non-static so we can use it
1436 (try_variable_definition): Use lookup_variable_in_set() rather
1437 than faking out current_variable_set_list by hand (cleanup).
1438 * variable.h: Add a prototype for the now non-static
1439 lookup_variable_in_set().
1441 2000-11-17 Paul D. Smith <psmith@gnu.org>
1443 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
1444 WINDOWS32 port to assume timestamps can be up to 3 seconds away
1445 before throwing a fit.
1447 2000-11-17 Paul D. Smith <psmith@gnu.org>
1449 * read.c (readline): CRLF calculations had a hole, if you hit the
1450 buffer grow scenario just right. Reworked the algorithm to avoid
1451 the need for len or lastlen at all. Problem description with
1452 sample code chages provided by Chris Faylor <cgf@redhat.com>.
1454 2000-10-24 Paul D. Smith <psmith@gnu.org>
1456 * gettext.c (SWAP): Declare this with the prototype, otherwise
1457 some systems don't work (non-32-bit? Reported for Cray T3E).
1458 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
1460 2000-10-05 Paul D. Smith <psmith@gnu.org>
1462 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
1463 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
1465 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
1467 2000-09-22 Paul D. Smith <psmith@gnu.org>
1469 * gettext.c: Don't #define _GETTEXT_H here; we only include some
1470 parts of the real gettext.h here, and we expect to really include
1471 the real gettext.h later. If we keep this #define, it's ignored.
1473 2000-09-21 Paul D. Smith <psmith@gnu.org>
1475 * main.c (log_working_directory): Rework the text to use complete
1476 sentences, to make life simpler for the translators.
1478 2000-08-29 Paul D. Smith <psmith@gnu.org>
1480 * file.c (remove_intermediates): Print a debug message before we
1481 remove intermediate files, so the user (if she uses -d) knows
1484 2000-08-21 Paul D. Smith <psmith@gnu.org>
1486 * variable.c (try_variable_definition): Change how we handle
1487 target-specific append variable defns: instead of just setting the
1488 value, expand it as an append _but_ only within the current
1489 target's context. Otherwise we lose all but the last value if the
1490 variable is appended more than once within the current target
1491 context. Fixes PR/1831.
1493 2000-08-16 Paul D. Smith <psmith@gnu.org>
1495 * function.c (func_shell): Nul-terminate the buffer before
1496 printing an exec error message (just in case it's not!).
1497 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
1499 2000-07-25 Paul D. Smith <psmith@gnu.org>
1501 * job.c (construct_command_argv_internal): Add "~" to the list of
1502 sh_chars[] which disallow optimizing out the shell call.
1504 2000-07-23 Paul Eggert <eggert@twinsun.com>
1506 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
1507 supersedes --disable-nsec-timestamps.
1508 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
1509 * README: Remove --disable-nsec-timestamps.
1511 * filedef.h (struct file.low_resolution_time): New member.
1512 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
1513 * remake.c (update_file_1):
1514 Avoid spurious rebuilds due to low resolution time stamps,
1515 generalizing the earlier code that applied only to archive members.
1516 (f_mtime): Archive members always have low resolution time stamps.
1518 * configure.in: Remove --disable-nsec-timestamps, as this has
1519 been superseded by .LOW_RESOLUTION_TIME.
1521 2000-07-23 Paul Eggert <eggert@twinsun.com>
1523 * configure.in (enable_nsec_timestamps): Renamed from
1524 make_cv_nsec_timestamps, since enable/disable options
1525 shouldn't be cached.
1527 2000-07-23 Bruno Haible <haible@clisp.cons.org>
1528 and Paul Eggert <eggert@twinsun.com>
1530 * file.c (file_timestamp_now):
1531 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
1532 so that clock_gettime is not linked unless needed.
1534 * filedef.h (FILE_TIMESTAMP_HI_RES):
1535 Remove definition; "configure" now does this.
1537 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
1538 to before high resolution file timestamp check,
1539 since that check now uses uintmax_t.
1540 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
1541 high resolution file timestamps.
1542 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
1543 so that we don't link in clock_gettime unnecessarily.
1545 2000-07-17 Paul D. Smith <psmith@gnu.org>
1547 * i18n/ja.po: New version of the translation file.
1549 2000-07-07 Paul D. Smith <psmith@gnu.org>
1551 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
1552 the offset calculation.
1553 (name_mtime): Replace EINTR test with EINTR_SET macro.
1555 2000-07-07 Paul Eggert <eggert@twinsun.com>
1559 * remake.c (update_file_1):
1560 Avoid spurious rebuilds of archive members due to their
1561 timestamp resolution being only one second.
1562 (f_mtime): Avoid spurious warnings of timestamps in the future due to
1563 the clock's resolution being lower than file timestamps'.
1564 When warning about future timestamps, report only the discrepancy,
1565 not the absolute value of the timestamp and the current time.
1567 * file.c (file_timestamp_now): New arg RESOLUTION.
1568 * filedef.h (file_timestamp_now): Likewise.
1569 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
1571 2000-07-05 Paul D. Smith <psmith@gnu.org>
1573 * variable.c (lookup_variable) [VMS]: Remove vestigial references
1574 to listp. Fixes PR/1793.
1576 2000-06-26 Paul Eggert <eggert@twinsun.com>
1578 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
1580 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
1582 * remake.c (f_mtime): Remove unused var memtime.
1584 2000-06-25 Martin Buchholz <martin@xemacs.org>
1586 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
1587 Ran spell-check on make.texinfo.
1589 2000-06-23 Paul D. Smith <psmith@gnu.org>
1591 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
1592 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
1593 * make.h: Define these macros.
1595 * Version 3.79.1 released.
1597 * configure.in: Add a new option, --disable-nsec-timestamps, to
