1 2005-02-01 Paul D. Smith <psmith@gnu.org>
3 * maintMakefile (po_repo): Update the GNU translation site URL.
5 2004-12-01 Paul D. Smith <psmith@gnu.org>
7 * main.c (main): Change char* env_shell to struct variable shell_var.
8 * variable.c (target_environment): Use new shell_var.
10 2004-11-30 Paul D. Smith <psmith@gnu.org>
12 * configure.in: The old way we avoided creating build.sh from
13 build.sh.in before build.sh.in exists doesn't work anymore; we
14 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
15 the help!). This also keeps automake from complaining.
16 * Makefile.am (README): Add a dummy target so automake won't
17 complain that this file doesn't exist when we checkout from CVS.
18 * maintMakefile (.dep_segment): Rewrite this rule since newer
19 versions of automake don't provide DEP_FILES.
21 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
23 Implementation of `realpath' and `abspath' built-in functions.
25 * configure.in: Check for realpath.
26 * function.c (abspath): Return an absolute file name that does
27 not contain any `.' or `..' components, nor repeated `/'.
28 * function.c (func_abspath): For each name call abspath.
29 * function.c (func_realpath): For each name call realpath
30 from libc or delegate to abspath if realpath is not available.
31 * doc/make.texi (Functions for File Names): Document new functions.
32 * doc/make.texi (Quick Reference): Ditto.
34 2004-11-28 Paul D. Smith <psmith@gnu.org>
36 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
37 arguments. Fixes bug #10252.
39 Fix for bug #1276: Handle SHELL according to POSIX requirements.
41 * main.c (main): Set SHELL to v_noexport by default. Remember the
42 original environment setting of SHELL in the env_shell variable.
43 * main.h: Export new env_shell variable.
44 * variable.c (target_environment): If we find a v_noexport
45 variable for SHELL, add a SHELL variable with the env_shell value.
46 * doc/make.texi (Quick Reference): Document the POSIX behavior.
47 * doc/make.texi (Variables/Recursion): Ditto.
49 2004-11-28 Paul D. Smith <psmith@gnu.org>
51 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
52 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
53 Patch by Alessandro Vesely.
55 2004-11-12 Paul D. Smith <psmith@gnu.org>
57 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
58 the command line if it's inside a string.
59 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
61 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
63 * function.c (func_lastword): New function: return last word
64 from the list of words.
65 * doc/make.texi: Document $(lastword ). Fix broken links in
66 Quick Reference section.
68 2004-10-06 Paul D. Smith <psmith@gnu.org>
70 Apply patch from Alessandro Vesely, provided with bug # 9748.
71 Fix use of tmpnam() to work with Borland C.
73 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
74 construction of a temporary filename, and call new function
75 create_batch_filename().
76 (create_batch_filename) [WINDOWS32]: New function to create a
79 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
81 * read.c (record_target_var): Expand simple pattern-specific
83 * variable.c (initialize_file_variables): Do not expand simple
84 pattern-specific variable.
86 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
88 * remake.c (update_file_1): When rebuilding makefiles inherit
89 dontcare flag from a target that triggered update.
91 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
93 * variable.c (initialize_file_variables): Mark pattern-specific
94 variable as a per-target and copy export status.
96 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
98 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
100 * implicit.c (pattern_search): When considering an implicit rule's
101 prerequisite check that it is actually a target rather then
102 just an entry in the file hashtable.
104 2004-09-21 Paul D. Smith <psmith@gnu.org>
106 * read.c (readstring): Fix some logic errors in backslash handling.
107 (eval): Remove some unnecessary processing in buffer handling.
108 (record_target_var): Assert that parse_variable_definition() succeeded.
109 Reported by: Markus Mauhart <qwe123@chello.at>.
111 * misc.c: Removed the sindex() function. All instances of this
112 function were trivially replaceable by the standard strstr()
113 function, and that function will always have better (or certainly
114 no worse) performance than the very simple-minded algorithm
115 sindex() used. This can matter with complex makefiles.
116 * make.h: Remove the prototype for sindex().
117 * function.c (subst_expand): Convert sindex() call to strstr().
118 This means we no longer need to track the TLEN value so remove that.
119 (func_findstring): Convert sindex() to strstr().
120 * commands.c (chop_commands): Convert sindex() calls to strstr().
121 Suggested by: Markus Mauhart <qwe123@chello.at>.
123 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
124 idea behind Savannah Patch #3144 from david.baird@homemail.com.
125 If SHELL is set to CMD.EXE then assume it's batch-mode and
126 non-unixy. I wrote the code differently from the patch, though,
127 to make it safer. This also resolves bug #9174.
129 2004-09-20 Paul D. Smith <psmith@gnu.org>
131 * expand.c (variable_expand_string): Modify to invoke
132 patsubst_expand() instead of subst_expand(); the latter didn't
133 handle suffix patterns correctly.
134 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
135 was used only from variable_expand_string() and is no longer used
137 (func_subst): Ditto, on call to subst_expand().
138 (patsubst_expand): Require the percent pointers to point to the
139 character after the %, not to the % itself.
140 * read.c (record_files): New call criteria for patsubst_expand().
141 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
142 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
144 2004-09-19 Paul D. Smith <psmith@gnu.org>
146 * function.c (subst_expand): Fix a check in by_word: look for a
147 previous blank if we're beyond the beginning of the string, not
148 the beginning of the word.
149 Bugs reported by Markus Mauhart <qwe123@chello.at>.
151 2004-05-16 Paul D. Smith <psmith@gnu.org>
153 * remake.c (update_goal_chain): Change the argument specifying
154 whether we're rebuilding makefiles to be a global variable,
155 REBUILDING_MAKEFILES.
156 (complain): Extract the code that complains about no rules to make
157 a target into a separate function.
158 (update_file_1): If we tried to rebuild a file during the makefile
159 rebuild phase and it was dontcare, then no message was printed.
160 If we then try to build the same file during the normal build,
161 print a message this time.
162 (remake_file): Don't complain about un-remake-able files when
163 we're rebuilding makefiles.
165 2004-05-11 Paul D. Smith <psmith@gnu.org>
167 * job.c (construct_command_argv_internal): OS/2 patches from
168 Andreas Buening <andreas.buening@nexgo.de>.
170 2004-05-10 Paul D. Smith <psmith@gnu.org>
172 * remake.c (update_file): Don't walk the double-colon chain unless
173 this is a double-colon rule. Fix suggested by Boris Kolpackov
174 <boris@kolpackov.net>.
176 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
177 * readme.vms: New section describing OpenVMS support and issues.
178 * default.c (default_variables): Add support for IA64.
179 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
180 without some privilege aborts make with the error
181 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
182 pressing Ctrl+Y and the input device is no terminal. The change
183 catches this error and just continues.
185 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
187 2004-04-25 Paul D. Smith <psmith@gnu.org>
189 * commands.c (set_file_variables): Set $< properly in the face of
190 order-only prerequisites.
191 Patch from Boris Kolpackov <boris@kolpackov.net>
193 2004-04-21 Bob Byrnes <byrnes@curl.com>
195 * main.c (main): Notice failures to remake makefiles.
197 2004-03-28 Paul D. Smith <psmith@gnu.org>
199 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
201 * job.c: No default shell for RISC OS.
202 (load_too_high): Hard-code the return to 1.
203 (construct_command_argv_internal): No sh_chars or sh_cmds.
204 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
206 2004-03-20 Paul D. Smith <psmith@gnu.org>
208 * variable.c (do_variable_definition): Don't append from the
209 global set if a previous non-appending target-specific variable
210 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
213 * expand.c (reference_variable): Don't give up on variables with
214 no value that have the target-specific append flag set: they might
215 have a value after all. Reported by Oliver Schmidt
216 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
217 <nikulin@dx1cmd.inp.nsk.su>.
219 * rule.c (count_implicit_rule_limits): Don't delete patterns which
220 refer to absolute pathnames in directories that don't exist: some
221 portion of the makefile could create those directories before we
222 match the pattern. Fixes bugs #775 and #108.
224 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
226 * main.c (main): Free makefile_mtimes if we have any.
227 * README.W32.template: Update documentation for the current status
228 of the MS-Windows port.
229 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
230 environment variable is sometimes already defined which causes the
232 * main.c (debug_signal_handler): Only define this function if
233 SIGUSR1 is available.
235 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
237 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
238 * README.OS2.template: Documentation updates.
239 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
240 link line for safety.
241 * maintMakefile (build.sh.in): Remove an extraneous ")".
242 * job.c (child_execute_job): Close saved FDs.
243 * job.c (exec_command) [OS/2]: exec_command(): If the command
244 can't be exec'ed and if the shell is not Unix-sh, then try again
245 with argv = { "cmd", "/c", ... }. Normally, this code is never
246 reached for the cmd shell unless the command really doesn't exist.
247 (construct_command_argv_internal) [OS/2]: The code for cmd
248 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
249 The CMD builtin commands are case insensitive so use strcasecmp().
251 2004-03-19 Paul D. Smith <psmith@gnu.org>
253 * read.c (do_define): Re-order line counter increment so the count
254 is accurate (we were losing one line per define). Reported by
255 Dave Yost <Dave@Yost.com>.
257 2004-03-06 Paul D. Smith <psmith@gnu.org>
259 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
261 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
262 * misc.c (message,error,fatal): Ditto.
263 * configh.dos.template: Define HAVE_ANSI_COMPILER.
264 * config.h.W32.template: Ditto.
265 * config.h-vms.template: Ditto.
266 * config.ami.template: Ditto.
268 2004-03-04 Paul D. Smith <psmith@gnu.org>
270 * README.template: Add a note about broken /bin/sh on SunOS
271 4.1.3_U1 & 4.1.4. Fix up Savannah links.
273 * misc.c (message, error, fatal): Don't use "..." if we're using
274 varargs. ansi2knr should handle this but it doesn't work: it
275 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
276 done. On many systems (SunOS for example) va_dcl is a #define.
277 So, force the use of the non-"..." version on pre-ANSI compilers.
279 * maintMakefile (sign-dist): Create some rules to help automate
280 the new GNU ftp upload method.
282 2004-02-24 Paul D. Smith <psmith@gnu.org>
284 * config.h.W32.template: Add HAVE_STDARG_H
285 * config.h-vms.template: Ditto.
286 * config.ami.template: Ditto.
288 2004-02-23 Jonathan Grant <jg-make@jguk.org>
290 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
291 * build_w32.bat: Remove extra "+".
293 2004-02-23 Paul D. Smith <psmith@gnu.org>
295 * make.h: Create an UNUSED macro to mark unused parameters.
296 * (many): Clean up warnings by applying UNUSED, fixing
297 signed/unsigned incompatibilities, etc.
299 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
301 * filedef.h: Name the command_state enumeration.
302 * file.c (set_command_state): Use the enumeration in the function
305 * configure.in: Explicitly set SET_MAKE to empty, to disable
306 MAKE=make even when no make already exists. Fix bug #3823.
308 2004-02-22 Paul D. Smith <psmith@gnu.org>
310 * maintMakefile: Perl script to clean up all non-CVS files. Use
311 it on all the subdirectories for the cvs-clean target.
313 * main.c (decode_switches): Require non-empty strings for all our
314 string command-line options. Fixes Debian bug # 164165.
316 * configure.in: Check for stdarg.h and varargs.h.
317 * make.h (USE_VARIADIC): Set this if we can use variadic functions
318 for printing messages.
319 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
324 A number of patches for OS/2 support from Andreas Buening
325 <andreas.buening@nexgo.de>:
327 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
328 disable the SIGCHLD handler.
329 (reap_children) [OS/2]: Remove special handling of job_rfd.
330 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
331 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
332 * main.c (main) [OS/2]: Special handling for paths in OS/2.
333 * configure.in [OS/2]: Force SA_RESTART for OS/2.
334 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
337 2004-02-21 Paul D. Smith <psmith@gnu.org>
339 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
340 <mail@kristov.de> reports that if process_begin() fails we don't
341 handle the error condition correctly in all cases.
342 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
343 to have a newline on the message.
345 * job.c (construct_command_argv_internal): Add "test" to UNIX
346 sh_cmds[]. Fixes Savannah bug # 7606.
348 2004-02-04 Paul D. Smith <psmith@gnu.org>
350 * job.c (vms_handle_apos) [VMS]: Fix various string handling
351 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
352 Hartmut Becker <Hartmut.Becker@hp.com>.
354 2004-01-21 Paul D. Smith <psmith@gnu.org>
356 * job.c (load_too_high): Implement an algorithm to control the
357 "thundering herd" problem when using -l to control job creation
358 via the load average. The system only recomputes the load once a
359 second but we can start many jobs in a second. To solve this we
360 keep track of the number of jobs started in the last second and
361 apply a weight to try to guess what a correct load would be.
362 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
363 Also fixes bug #4693.
364 (reap_children): Decrease the job count for this second.
365 (start_job_command): Increase the job count for this second.
367 * read.c (conditional_line): Expand the text after ifn?def before
368 checking to see if it's a single word. Fixes bug #7257.
370 2004-01-09 Paul D. Smith <psmith@gnu.org>
372 * file.c (print_file): Recurse to print all targets in
373 double-colon rules. Fixes bug #4518, reported (with patch) by
374 Andrew Chatham <chatham@google.com>.
376 2004-01-07 Paul D. Smith <psmith@gnu.org>
378 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
379 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
380 AC_FUNC_SETVBUF_REVERSED.
382 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
383 (MAKE Variable): Fix Savannah bug #4898.
385 * job.c (construct_command_argv_internal): Add "!" to the list of
386 shell escape chars. POSIX sh allows it to appear before a
387 command, to negate the exit code. Fixes bug #6404.
389 * implicit.c (pattern_search): When matching an implicit rule,
390 remember which dependencies have the ignore_mtime flag set.
391 Original fix provided in Savannah patch #2349, by Benoit
392 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
394 2003-11-22 Paul D. Smith <psmith@gnu.org>
396 * README.W32.template (Outputs): Clarification on -j with
397 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
400 2003-11-02 Paul D. Smith <psmith@gnu.org>
402 * function.c (func_if): Strip all the trailing whitespace from the
403 condition, then don't expand it. Fixed bug # 5798.
405 * expand.c (recursively_expand_for_file): If we're expanding a
406 variable with no file context, then use the variable's context.
409 2003-10-21 Paul D. Smith <psmith@gnu.org>
411 * main.c (log_working_directory): Add newlines to printf()s.
413 * README.cvs: Add a note to ignore warnings during autoreconf.
415 * maintMakefile (po_repo): Set a new URL for PO file updates.
416 (get-config/config.guess get-config/config.sub): Get these files
417 from the Savannah config project instead of ftp.gnu.org.
419 2003-10-05 Paul Eggert <eggert@twinsun.com>
421 * main.c (main): Avoid potential subscript error if environ has
424 2003-08-22 Paul D. Smith <psmith@gnu.org>
426 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
427 systems which don't yet implement the C89 standard :-/.
429 2003-07-18 Paul D. Smith <psmith@gnu.org>
431 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
432 [WINDOWS32]: Initialize hash.
434 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
436 * dir.c (read_dirstream): Provide a workaround for broken versions of
437 the MinGW dirent structure.
439 2003-05-30 Earnie Boyd <earnie@users.sf.net>
441 * w32/include/dirent.h: Add __MINGW32__ filter.
443 2003-05-30 Earnie Boyd <earnie@users.sf.net>
445 * make.h: Add global declaration of *make_host.
446 * main.c (print_usage): Remove local declaration of *make_host.
447 (print_version): Display "This program built for ..." after Copyright
450 2003-05-30 Earnie Boyd <earnie@users.sf.net>
452 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
453 execution of "makeinfo --html make.texi".
455 2003-04-30 Paul D. Smith <psmith@gnu.org>
457 * build.template: Make some changes to maybe allow this script to
458 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
460 * README.OS2.template: New file for OS/2 support. Original
461 contributed by Andreas Buening.
462 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
465 2003-04-19 Paul D. Smith <psmith@gnu.org>
467 Fix bug #1405: allow a target to match multiple pattern-specific
470 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
471 variable.c, where they've always belonged.
472 * rule.h: Move the prototypes and struct pattern_var as well.
473 * variable.c (initialize_file_variables): Invoke
474 lookup_pattern_var() in a loop, until no more matches are found.
475 If a match is found, create a new variable set for the target's
476 pattern variables. Then merge the contents of each matching
477 pattern variable set into the target's pattern variable set.
478 (lookup_pattern_var): Change this function to be usable
479 in a loop. It takes a starting position: if NULL, start at the
480 beginning; if non-NULL, start with the pattern variable after that
481 position, and return the next matching pattern.
482 (create_pattern_var): Create a unique instance of
483 pattern-specific variables for every definition in the makefile.
484 Don't combine the same pattern together. This allows us to
485 process the variable handling properly even when the same pattern
486 is used multiple times.
487 (parse_variable_definition): New function: break out the parsing
488 of a variable definition line from try_variable_definition.
489 (try_variable_definition): Call parse_variable_definition to
491 (print_variable_data_base): Print out pattern-specific variables.
492 * variable.h (struct variable): Remember when a variable is
493 conditional. Also remember its flavor.
494 (struct pattern_var): Instead of keeping a variable set, we just
495 keep a single variable for each pattern.
496 * read.c (record_target_var): Each pattern variable contains only a
497 single variable, not a set, so create it properly.
498 * doc/make.texi (Pattern-specific): Document the new behavior.
500 2003-04-17 Paul D. Smith <psmith@gnu.org>
502 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
503 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
504 file/directory naming rules for VMS so I can't tell whether this
507 2003-04-09 Paul D. Smith <psmith@gnu.org>
509 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
510 DOS-style pathnames: backslash separators and drive specifiers.
512 2003-03-28 Paul D. Smith <psmith@gnu.org>
514 * file.c (snap_deps): If .SECONDARY with no targets is given, set
515 the intermediate flag on all targets. Fixes bug #2515.
517 2003-03-24 Paul D. Smith <psmith@gnu.org>
519 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
520 Upgrade to autoconf 2.57 and automake 1.7.3.
522 * job.c: More OS/2 changes from Andreas Buening.
524 * file.c (print_file): Fix variable initialization.
527 * remake.c (notice_finished_file):
529 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
530 some calls (like readdir()) return NULL in valid situations
531 without resetting errno. Fixes bug #2846.

535 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
537 * job.c (_is_unixy_shell) [OS/2]: New function.
538 Set default shell to /bin/sh.
539 (reap_children): Close the job_rfd pipe here since we don't use a
541 (set_child_handler_action_flags): define this to empty on OS/2.
542 (start_job_command): Close the jobserver pipe and use
543 child_execute_job() instead of fork/exec.
544 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
545 rather than exec'ing, then reconfigure stdin/stdout.
546 (exec_command): Rewrite to use spawn instead of exec. Return the
549 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
550 in DOS. Handle the TEMP environment variable as in DOS. Don't
551 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
552 use -j in DOS mode. Use child_execute_job() instead of
555 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
558 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
559 prototypes that return values.
561 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
563 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
564 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
566 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
569 2003-02-24 Paul D. Smith <psmith@gnu.org>
571 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
572 * job.c (child_execute_job) [VMS]: New code for handling spawn().
573 (child_execute_job) [VMS]: Handle error status properly.
574 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
576 * function.c (func_shell): Use EINTRLOOP() while reading from the
577 subshell pipe (Fixes bug #2502).
578 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
580 * main.c (main): Ditto.
582 2003-01-30 Paul D. Smith <psmith@gnu.org>
584 * read.c (eval): eval() was not fully reentrant, because the
585 collapsed buffer was static. Change it to be an automatic
586 variable so that eval() can be invoked recursively.
588 (eval): Apply patch # 1022: fix memory reference error on long
589 target-specific variable lines.
590 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
592 * function.c (check_numeric): Combine the is_numeric() function
593 into this function, since it's only called from one place.
594 Constify this function. Have it print the incorrect string in the
595 error message. Fixes bug #2407.
596 (strip_whitespace): Constify.
598 * expand.c (expand_argument): Constify.
600 2003-01-29 Paul D. Smith <psmith@gnu.org>
602 Fix bug # 2169, also reported by other people on various systems.
604 * make.h: Some systems, such as Solaris and PTX, do not fully
605 implement POSIX-compliant SA_RESTART functionality; important
606 system calls like stat() and readdir() can still fail with EINTR
607 even if SA_RESTART has been set on the signal handler. So,
608 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
609 EINTR for system calls which return -1 or 0 (NULL), respectively,
611 Also, remove the old atomic_stat()/atomic_readdir() and
612 HAVE_BROKEN_RESTART handling.
614 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
616 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
617 * remake.c (touch_file): Ditto.
619 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
620 * read.c (construct_include_path): Ditto.
621 * remake.c (name_mtime): Ditto.
622 * vpath.c (selective_vpath_search): Ditto.
623 * dir.c (find_directory): Ditto.
625 (find_directory): Use ENULLLOOP() to wrap opendir().
626 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
628 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
629 atomic_readdir() handling.
631 2003-01-22 Paul D. Smith <psmith@gnu.org>
633 * function.c (func_call): Fix Bug #1744. If we're inside a
634 recursive invocation of $(call ...), mask any of the outer
635 invocation's arguments that aren't used by this one, so that this
636 invocation doesn't "inherit" them accidentally.
638 2002-12-05 Paul D. Smith <psmith@gnu.org>
640 * function.c (subst_expand): Valery Khamenia reported a
641 pathological performance hit when doing substitutions on very
642 large values with lots of words: turns out we were invoking
643 strlen() a ridiculous number of times. Instead of having each
644 call to sindex() call strlen() again, keep track of how much of
645 the text we've seen and pass the length to sindex().
647 2002-11-19 Paul D. Smith <psmith@gnu.org>
649 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
652 2002-11-16 Paul D. Smith <psmith@gnu.org>
654 * NMakefile.template (OBJS): Add hash.c object file.
655 * SMakefile.template (srcs): Ditto.
656 * Makefile.ami (objs): Ditto.
657 * build_w32.bat: Ditto.
659 * Makefile.DOS.template: Remove extra dependencies.
661 2002-10-25 Paul D. Smith <psmith@gnu.org>
663 * expand.c (install_variable_buffer): New function. Install a new
664 variable_buffer context and return the previous one.
665 (restore_variable_buffer): New function. Free the current
666 variable_buffer context and put a previously saved one back.
667 * variable.h: Prototypes for {install,restore}_variable_buffer.
668 * function.c (func_eval): Push a new variable_buffer context
669 before we eval, then restore the old one when we're done.
672 * read.c (install_conditionals): New function. Install a new
673 conditional context and return the previous one.
674 (restore_conditionals): New function. Free the current
675 conditional context and put a previously saved one back.
676 (eval): Use the {install,restore}_conditionals for "include"
678 (eval_buffer): Use {install,restore}_conditionals to preserve the
679 present conditional state before we evaluate the buffer.
682 * doc/make.texi (Quick Reference): Add references to $(eval ...)
684 (Recursion): Add a variable index entry for CURDIR.
686 * README.cvs: Update to appropriate versions.
687 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
688 don't need to copy loadavg.c: automake is smart enough to create
689 it for me. Still have a bug in automake related to ansi2knr tho.
691 2002-10-14 Paul D. Smith <psmith@gnu.org>
693 * remake.c (notice_finished_file): Only touch targets if they have
694 at least one command (as per POSIX). Resolve Bug #1418.
696 * *.c: Convert to using ANSI C-style function definitions.
697 * Makefile.am: Enable the ansi2knr feature of automake.
698 * configure.in: ditto.
700 2002-10-13 Paul D. Smith <psmith@gnu.org>
702 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
703 for automatic variable values like $^, etc. In the case of very
704 large lists of prerequisites this causes problems. Instead reuse
705 a static buffer (resizeable) for each variable.
707 * read.c (eval): Fix Bug #1391: allow "export" keyword in
708 target-specific variable definitions. Check for it and set an
710 (record_target_var): Set the export field to v_export if the
711 "exported" flag is set.
712 * doc/make.texi (Target-specific): Document the ability to use
715 * doc/make.texi: Change the name of the section on automatic
716 variables from "Automatic" to "Automatic Variables". Added text
717 clarifying the scope of automatic variables.
719 2002-10-04 Paul D. Smith <psmith@gnu.org>
721 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
723 (record_files): Ditto.
725 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
726 the search for the '=' to only within the enclosing parens.
728 2002-10-03 Paul D. Smith <psmith@gnu.org>
730 Version 3.80 released.
732 * dir.c: Change hash functions to use K&R function definition style.
737 Update to automake 1.7.
739 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
740 (pdf): Remove this target as automake now provides one.
742 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
744 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
746 * makefile.com: Updates for GNU make 3.80.
747 * makefile.vms: Ditto.
749 2002-09-23 Paul D. Smith <psmith@gnu.org>
751 * read.c (enum make_word_type): Remove w_comment.
752 (get_next_mword): Don't treat comment characters as special; where
753 this function is used we will never see a comment (it's stripped
754 before we get here) and treating comments specially means that
755 targets like "foo\#bar" aren't handled properly.
757 2002-09-18 Paul D. Smith <psmith@gnu.org>
759 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
761 * read.c (eval): Expansion of arguments to export/unexport was
762 ignoring all arguments after the first one. Change the algorithm
763 to expand the whole line once, then parse the results.
765 2002-09-17 Paul D. Smith <psmith@gnu.org>
767 Fix Bug #940 (plus another bug I found while looking at this):
769 * read.c (record_target_var): enter_file() will add a new entry if
770 it's a double-colon target: we don't want to do that in this
771 situation. Invoke lookup_file() and only enter_file() if it does
772 not already exist. If the file we get back is a double-colon then
773 add this variable to the "root" double-colon target.
775 * variable.c (initialize_file_variables): If this file is a
776 double-colon target but is not the "root" target, then initialize
777 the root and make the root's variable list the parent of our
780 2002-09-13 Paul D. Smith <psmith@gnu.org>
782 * doc/make.texi (MAKE Variable): Add some indexing for "+".
784 * hash.c (round_up_2): Get rid of a warning.
786 2002-09-12 Paul D. Smith <psmith@gnu.org>
788 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
789 so it doesn't complain about getloadavg.c.
791 * commands.c (set_file_variables): Make sure we always alloca() at
792 least 1 character for the value of $? (for '\0').
794 2002-09-11 Paul D. Smith <psmith@gnu.org>
796 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
797 macro to use RESULT instead of the incorrect _RESULT_.
799 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
800 and atomic_readdir(). We need to #include dirent.h to get this to
802 * misc.c (atomic_readdir): Fix typos.
804 2002-09-10 Paul D. Smith <psmith@gnu.org>
806 * read.c (eval): Expand variable lists given to export and
807 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
808 (conditional_line): Ditto for "ifdef". Fixes bug #103.
810 * doc/make.texi (Variables/Recursion): Document this.
811 (Conditional Syntax): And here.
813 2002-09-09 Paul D. Smith <psmith@gnu.org>
815 * configure.in: Check for memmove().
817 2002-09-07 Paul D. Smith <psmith@gnu.org>
819 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
820 Michael Sterrett <msterret@coat.com> reports that while it has
821 SA_RESTART, it does not work properly.
823 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
824 that invokes stat() and loops to do it again if it returns EINTR.
825 (atomic_readdir): Ditto, with readdir().
827 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
828 and readdir() to atomic_stat() and atomic_readdir().
830 2002-09-04 Paul D. Smith <psmith@gnu.org>
832 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
833 reports that GNU make sometimes doesn't recognize that targets can
834 be made, when directories can be created as prerequisites. He
835 reports that changing the order of predicates in the DEP->changed
836 flag test so that lookup_file() is always performed, solves this
839 2002-08-08 Paul D. Smith <psmith@gnu.org>
841 * configure.in: Require a newer version of gettext.
843 * misc.c (perror_with_name): Translate the format string (for
844 right-to-left language support).
845 (pfatal_with_name): Ditto.
847 * main.c: Create a static array of strings to store the usage
848 text. This is done to facilitate translations.
849 (struct command_switch): Remove argdesc and description fields.
850 (switches): Remove values for obsolete fields.
851 (print_usage): Print each element of the usage array.
853 * hash.c: Change function definitions to be K&R style.
855 2002-08-02 Paul D. Smith <psmith@gnu.org>
857 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
858 this one because it's too hard to get right. We'll look at it for
860 * main.c (main): Don't create the .TARGETS variable.
861 * variable.c (handle_special_var): Don't handle .TARGETS.
863 2002-08-01 Paul D. Smith <psmith@gnu.org>
865 * main.c (switches): Add a new option, -B (--always-make). If
866 specified, make will rebuild all targets that it encounters even
867 if they don't appear to be out of date.
868 (always_make_flag): New flag.
869 * make.h: Extern always_make_flag.
870 * remake.c (update_file_1): Check always_make_flag; if it's set we
871 will always rebuild any target we can, even if none of its
872 prerequisites are newer.
875 * doc/make.texi (Shell Function): Make it clear that make
876 variables marked as "export" are not passed to instances of the
879 Add new introspection variable .VARIABLES and .TARGETS.
881 * variable.c (handle_special_var): New function. If the variable
882 reference passed in is "special" (.VARIABLES or .TARGETS),
883 calculate the new value if necessary. .VARIABLES is handled here:
884 walk through the hash of defined variables and construct a value
885 which is a list of the names. .TARGETS is handled by
887 (lookup_variable): Invoke handle_special_var().
888 * file.c (build_target_list): Walk through the hask of known files
889 and construct a list of the names of all the ones marked as
891 * main.c (main): Initialize them to empty (and as simple variables).
892 * doc/make.texi (Special Variables): Document them.
893 * NEWS: Mention them.
895 * variable.h (struct variable): Add a new flag "exportable" which
896 is true if the variable name is valid for export.
897 * variable.c (define_variable_in_set): Set "exportable" when a new
899 (target_environment): Use the "exportable" flag instead of
900 re-checking the name here... an efficiency improvement.
902 2002-07-31 Paul D. Smith <psmith@gnu.org>
904 * config.h-vms.template: Updates to build on VMS. Thanks to
905 Brian_Benning@aksteel.com for helping verify the build.
906 * makefile.com: Build the new hash.c file.
907 * hash.h: Use strcpmi(), not stricmp(), in the
908 HAVE_CASE_INSENSITIVE_FS case.
910 2002-07-30 Paul D. Smith <psmith@gnu.org>
912 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
913 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
914 Reported by <Brian_Benning@aksteel.com>.
916 2002-07-10 Paul D. Smith <psmith@gnu.org>
918 * variable.c (pop_variable_scope): Remove variable made unused by
919 new hash infrastructure.
920 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
921 comparisons as well as name comparisons.
922 * variable.h: Add a prototype for new hash_init_function_table().
923 * file.c (lookup_file): Remove variables made unused by new hash
925 * dir.c (directory_contents_hash_2): Missing return of hash value.
926 (dir_contents_file_exists_p): Remove variables made unused by new
930 Installed Greg McGary's integration of the hash functions from the
931 GNU id-utils package:
933 2002-07-10 Greg McGary <greg@mcgary.org>
935 * scripts/functions/filter-out: Add literals to to the
936 pattern space in order to add complexity, and trigger
937 use of an internal hash table. Fix documentation strings.
938 * scripts/targets/INTERMEDIATE: Reverse order of files
939 passed to expected `rm' command.

1033 2002-07-10 Paul D. Smith <psmith@gnu.org>
1035 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
1036 prerequisite list. A real SysV make will expand the entire
1037 prerequisites list _twice_: we don't do that as it's a big
1038 backward-compatibility problem. We only replace those specific
1041 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
1042 references left in the list of prerequisites. Check for .POSIX as
1043 we record targets, so we can disable non-POSIX behavior while
1044 reading makefiles as well as running them.
1045 (eval): Check the prerequisite list to see if we have anything
1046 that looks like a SysV prerequisite variable reference.
1048 2002-07-09 Paul D. Smith <psmith@gnu.org>
1050 * doc/make.texi (Prerequisite Types): Add a new section describing
1051 order-only prerequisites.
1053 * read.c (uniquize_deps): If we have the same file as both a
1054 normal and order-only prereq, get rid of the order-only prereq,
1055 since the normal one supersedes it.
1057 2002-07-08 Paul D. Smith <psmith@gnu.org>
1059 * AUTHORS: Added Greg McGary to the AUTHORS file.
1060 * NEWS: Blurbed order-only prerequisites.
1061 * file.c (print_file): Show order-only deps properly when printing
1064 * maintMakefile: Add "update" targets for wget'ing the latest
1065 versions of various external files. Taken from Makefile.maint in
1068 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
1069 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
1071 2002-07-07 Paul D. Smith <psmith@gnu.org>
1073 * po/*.po: Remove. We'll use wget to retrieve them at release
1076 * variable.c (do_variable_definition) [W32]: On W32 using cmd
1077 rather than a shell you get an exception. Make sure we look up
1078 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
1080 * remake.c (notice_finished_file): Fix handling of -t flag.
1081 Patch provided by Henning Makholm <henning@makholm.net>.
1083 * implicit.c (pattern_search): Some systems apparently run short
1084 of stack space, and using alloca() in this function caused an
1085 overrun. I modified it to use xmalloc() on the two variables
1086 which seemed like they might get large. Fixes Bug #476.
1088 * main.c (print_version): Update copyright notice to conform with
1090 (print_usage): Update help output.
1092 * function.c (func_eval): Create a new make function, $(eval
1093 ...). Expand the arguments, put them into a buffer, then invoke
1094 eval_buffer() on the resulting string.
1095 (func_quote): Create a new function, $(quote VARNAME). Inserts
1096 the value of the variable VARNAME without expanding it any
1099 * read.c (struct ebuffer): Change the linebuffer structure to an
1100 "eval buffer", which can be either a file or a buffer.
1101 (eval_makefile): Move the code in the old read_makefile() which
1102 located a makefile into here: create a struct ebuffer with that
1103 information. Have it invoke the new function eval() with that
1105 (eval_buffer): Create a new function that creates a struct ebuffer
1106 that holds a string buffer instead of a file. Have it invoke
1107 eval() with that ebuffer.
1108 (eval): New function that contains the guts of the old
1109 read_makefile() function: this function parses makefiles. Obtains
1110 data to parse from the provided ebuffer. Some modifications to
1111 make the flow of the function cleaner and clearer. Still could
1112 use some work here...
1113 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
1114 contents of the define/endef variable from the ebuffer.
1115 (readstring): Read the next line from a string-style ebuffer.
1116 (readline): Read the next line from an ebuffer. If it's a string
1117 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
1120 * dep.h (eval_buffer): Prototype eval_buffer();
1122 * variable.c (do_variable_definition): Make sure that all
1123 non-target-specific variables are registered in the global set.
1124 If we're invoked from an $(eval ...) we might be inside a $(call
1125 ...) or other function which has pushed a variable scope; we still
1126 want to define our variables from evaluated makefile code in the
1129 2002-07-03 Greg McGary <greg@mcgary.org>
1131 * dep.h (struct dep) [ignore_mtime]: New member.
1132 [changed]: convert to a bitfield.
1133 * implicit.c (pattern_search): Zero ignore_mtime.
1134 * main.c (main, handle_non_switch_argument): Likewise.
1135 * rule.c (convert_suffix_rule): Likewise.
1136 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
1137 (read_makefile): Parse '|' in prerequisite list.
1138 (uniquize_deps): Consider ignore_mtime when comparing deps.
1139 * remake.c (update_file_1, check_dep): Don't force remake for
1140 dependencies that have d->ignore_mtime.
1141 * commands.c (FILE_LIST_SEPARATOR): New constant.
1142 (set_file_variables): Don't include a
1143 prerequisite in $+, $^ or $? if d->ignore_mtime.
1146 2002-06-18 Paul D. Smith <psmith@gnu.org>
1148 * make.texinfo: Updates for next revision. New date/rev/etc.
1149 Recreate all Info menus. Change license on the manual to the GNU
1150 Free Documentation License. A number of typos.
1151 (Variables Simplify): Don't use "-" before it's defined.
1152 (Automatic Prerequisites): Rewrite the target example to work
1153 properly if the compile fails. Remove incorrect comments about
1154 how "set -e" behaves.
1155 (Text Functions): Move the "word", "wordlist", "words", and
1156 "firstword" functions here, from "File Name Functions".
1157 * make-stds.texi: Update from latest GNU version.
1158 * fdl.texi: (created) Import the latest GNU version.
1160 2002-06-06 Paul D. Smith <psmith@gnu.org>
1162 * variable.c (do_variable_definition): New function: extract the
1163 part of try_variable_definition() that actually sets the value
1164 into a separate function.
1165 (try_variable_definition): Call do_variable_definition() after
1166 parsing the variable definition string.
1167 (define_variable_in_set): Make the name argument const.
1169 * variable.h (enum variable_flavor): Make public.
1170 (do_variable_definition): Create prototype.
1172 * read.c (read_all_makefiles): Create a new built-in variable,
1174 (read_makefile): Add each makefile read in to this variable value.
1176 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
1178 * Makefile.DOS.template: Tweak according to changes in the
1179 distribution. Add back the dependencies of *.o files.
1181 * configh.dos.template: Synchronize with config.h.in.
1183 2002-05-09 Paul D. Smith <psmith@gnu.org>
1185 * file.c (file_timestamp_now): Use K&R function declaration.
1187 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
1188 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
1189 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
1190 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
1191 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
1192 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
1193 nlist.n_name is a pointer rather than an array.
1195 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
1196 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
1197 * configure.in: Use it instead of the old version.
1199 * main.c (main): Prefer setvbuf() to setlinebuf().
1201 2002-05-08 Paul D. Smith <psmith@gnu.org>
1203 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
1204 (loadavg_LDADD): Ditto.
1206 2002-04-29 Paul D. Smith <psmith@gnu.org>
1208 * expand.c (recursively_expand_for_file): Rename
1209 recursively_expand() to recursively_expand_for_file() and provide
1210 an extra argument, struct file. If the argument is provided, set
1211 the variable scope to that of the file before expanding.
1212 * variable.h (recursively_expand): Make this a macro that invokes
1213 recursively_expand_for_file() with a NULL file pointer.
1214 * variable.c (target_environment): Call the renamed function and
1215 provide the current file context.
1216 Fixes Debian bug #144306.
1218 2002-04-28 Paul D. Smith <psmith@gnu.org>
1220 Allow $(call ...) user-defined variables to be self-referencing
1221 without throwing an error. Allows implementation of transitive
1222 closures, among other possibly useful things.
1223 Requested by: Philip Guenther <guenther@sendmail.com>
1225 * variable.h (struct variable): Add a new field: exp_count, and
1226 new macros to hold its size and maximum value.
1227 (warn_undefined): Make this a macro.
1228 * variable.c (define_variable_in_set): Initialize it.
1229 * expand.c (recursively_expand): If we detect recursive expansion
1230 of a variable, check the exp_count field. If it's greater than 0
1231 allow the recursion and decrement the count.
1232 (warn_undefined): Remove this (now a macro in variable.h).
1233 * function.c (func_call): Before we expand the user-defined
1234 function, modify its exp_count field to contain the maximum
1235 number of recursive calls we'll allow. After the call, reset it
1238 2002-04-21 Paul D. Smith <psmith@gnu.org>
1240 Modified to use latest autoconf (2.53), automake (1.6.1), and
1241 gettext (0.11.1). We're using gettext's new "external" support,
1242 to avoid including libintl source with GNU make.
1244 * README.cvs: New file. Explain how to build GNU make from CVS.
1246 * configure.in: Modify checking for the system glob library.
1247 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
1248 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
1249 etc. will manage it correctly). Set an automake conditional
1250 USE_LOCAL_GLOB to decide whether to compile the glob library.
1252 * getloadavg.c (main): Include make.h in the "TEST" program to
1255 * Makefile.am: Remove special rules for loadavg. Replace them
1256 with Automake capabilities for building extra programs.
1258 * signame.c: This file does nothing if the system provide
1259 strsignal(). If not, it implements strsignal(). If the system
1260 doesn't define sys_siglist, then we make our own; otherwise we use
1262 * signame.h: Removed.
1264 * main.c (main): No need to invoke signame_init(). Update copyright.
1266 * ABOUT-NLS: Removed.
1267 * gettext.c: Removed.
1268 * gettext.h: Get a simplified copy from the gettext package.
1270 * i18n/*.po: Moved to po/.
1273 * config/*: Created. Contains package configuration helper files.
1274 * config.guess, config.sub: Moved to config directory.
1276 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
1277 Rework to use new-style autoconf features. Use the "external"
1278 mode for gettext. Make the build.sh config file conditional on
1279 whether build.sh.in exists, to avoid autoconf errors.
1280 * acinclude.m4: Removed almost all macros as being obsolete.
1281 Rewrote remaining macros to use AC_DEFINE.
1282 * acconfig.h: Removed.
1284 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
1285 conditional to handle customs support. Remove special handling
1288 2002-04-20 Paul D. Smith <psmith@gnu.org>
1290 * function.c (func_call): Don't mark the argument variables $1,
1291 etc. as recursive. They've already been fully expanded so
1292 there's no need to do it again, and doing so strips escaped $'s.
1293 Reported by Sebastian Glita <glseba@yahoo.com>.
1295 * remake.c (notice_finished_file): Walk through double-colon
1296 entries via the prev field, not the next field!
1297 Reported by Greg McGary <greg@mcgary.org>.
1299 * main.c (main): If the user specifies -q and asks for a specific
1300 target which is a makefile, we got an assert. In that case it
1301 turns out we should continue normally instead.
1303 * i18n/de.po, i18n/fr.po: Installed an updated translation.
1305 * i18n/he.po: Installed a new translation.
1307 2002-01-07 Paul D. Smith <psmith@gnu.org>
1309 * i18n/es.po, i18n/ru.po: Installed an updated translation.
1311 2001-12-04 Paul D. Smith <psmith@gnu.org>
1313 * i18n/ja.po: Installed an updated translation.
1315 2001-09-04 Paul D. Smith <psmith@gnu.org>
1317 * i18n/da.po: Installed an updated translation.
1319 2001-08-03 Paul D. Smith <psmith@gnu.org>
1321 * i18n/fr.po: Installed an updated translation.
1322 Resolves Debian bug #106720.
1324 2001-06-13 Paul D. Smith <psmith@gnu.org>
1326 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
1329 2001-06-11 Paul D. Smith <psmith@gnu.org>
1331 * i18n/ko.po: Installed a new translation.
1333 2001-05-06 Paul D. Smith <psmith@gnu.org>
1335 Modify the EINTR handling.
1337 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
1338 the way in which we manage the file descriptor/signal handler race
1339 trap to be more efficient.
1341 2001-05-06 Paul Eggert <eggert@twinsun.com>
1343 Restart almost all system calls that are interrupted, instead
1344 of worrying about EINTR. The lone exception is the read() for
1347 * configure.in (HAVE_SA_RESTART): New macro.
1348 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
1349 * main.c (main): Use SA_RESTART instead of the old,
1350 nonstandard SA_INTERRUPT.
1352 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
1353 * main.c (bsd_signal): New function or macro,
1354 if the implementation doesn't supply it.
1355 (The bsd_signal function will be in POSIX 1003.1-200x.)
1356 (HANDLESIG): Remove.
1357 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
1359 * make.h (EINTR_SET): Remove.
1360 (SA_RESTART): New macro.
1362 * arscan.c (ar_member_touch): Don't worry about EINTR.
1363 * function.c (func_shell): Likewise.
1364 * job.c (reap_children, free_child, new_job): Likewise.
1365 * main.c (main): Likewise.
1366 * remake.c (touch_file, name_mtime): Likewise.
1368 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
1369 if fstat failed with errno!=EINTR, the error was ignored.
1371 * job.c (set_child_handler_action_flags): New function.
1372 (new_job): Use it to temporarily clear the SIGCHLD action flags
1373 while reading the token.
1375 2001-05-02 Paul D. Smith <psmith@gnu.org>
1377 * job.c (start_job_command): Don't add define/endef per-line flags
1378 to the top-level flags setting.
1380 2001-04-03 Paul D. Smith <psmith@gnu.org>
1382 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
1383 bit on error, so check for odd return values, not non-0 return
1385 (VMS_get_member_info): Calculate the timezone differences correctly.
1386 Reported by John Fowler <jfowler@nyx.net>.
1389 2001-03-14 Paul D. Smith <psmith@gnu.org>
1391 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
1392 value before invoking define_variable().
1393 Reported by John Fowler <jfowler@nyx.net>.
1395 2001-02-07 Paul D. Smith <psmith@gnu.org>
1397 * read.c (record_target_var): If we reset the variable due to a
1398 command-line variable setting overriding it, turn off the "append"
1401 2001-01-17 Paul D. Smith <psmith@gnu.org>
1403 * variable.c (lookup_variable) [VMS]: When getting values from the
1404 environment, allocate enough space for the _value_ plus escapes,
1405 not enough space for the name plus escapes :-/.
1406 Reported by John Fowler <jfowler@nyx.net>.
1408 * remake.c (f_mtime): Removed the "***" prefix from the mod time
1409 warnings that make generates, so it doesn't look like an error.
1410 Reported by Karl Berry <karl@gnu.org>.
1413 Fix for PR/2020: Rework appended target-specific variables. I'm
1414 fairly confident this algorithm is finally correct.
1416 * expand.c (allocated_variable_append): Rewrite. Instead of
1417 expanding each appended variable then adding all the expanded
1418 strings together, we append all the unexpanded values going up
1419 through the variable set contexts, then expand the final result.
1420 This behaves just like non-target-specific appended variable
1421 values, while the old way didn't in various corner cases.
1422 (variable_append): New function: recursively append the unexpanded
1423 value of a variable, walking from the outermost variable scope to
1425 * variable.c (lookup_variable): Remove the code that looked up the
1426 variable set list if the found variable was "append". We don't
1428 (lookup_variable_in_set): Make this non-static so we can use it
1430 (try_variable_definition): Use lookup_variable_in_set() rather
1431 than faking out current_variable_set_list by hand (cleanup).
1432 * variable.h: Add a prototype for the now non-static
1433 lookup_variable_in_set().
1435 2000-11-17 Paul D. Smith <psmith@gnu.org>
1437 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
1438 WINDOWS32 port to assume timestamps can be up to 3 seconds away
1439 before throwing a fit.
1441 2000-11-17 Paul D. Smith <psmith@gnu.org>
1443 * read.c (readline): CRLF calculations had a hole, if you hit the
1444 buffer grow scenario just right. Reworked the algorithm to avoid
1445 the need for len or lastlen at all. Problem description with
1446 sample code chages provided by Chris Faylor <cgf@redhat.com>.
1448 2000-10-24 Paul D. Smith <psmith@gnu.org>
1450 * gettext.c (SWAP): Declare this with the prototype, otherwise
1451 some systems don't work (non-32-bit? Reported for Cray T3E).
1452 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
1454 2000-10-05 Paul D. Smith <psmith@gnu.org>
1456 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
1457 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
1459 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
1461 2000-09-22 Paul D. Smith <psmith@gnu.org>
1463 * gettext.c: Don't #define _GETTEXT_H here; we only include some
1464 parts of the real gettext.h here, and we expect to really include
1465 the real gettext.h later. If we keep this #define, it's ignored.
1467 2000-09-21 Paul D. Smith <psmith@gnu.org>
1469 * main.c (log_working_directory): Rework the text to use complete
1470 sentences, to make life simpler for the translators.
1472 2000-08-29 Paul D. Smith <psmith@gnu.org>
1474 * file.c (remove_intermediates): Print a debug message before we
1475 remove intermediate files, so the user (if she uses -d) knows
1478 2000-08-21 Paul D. Smith <psmith@gnu.org>
1480 * variable.c (try_variable_definition): Change how we handle
1481 target-specific append variable defns: instead of just setting the
1482 value, expand it as an append _but_ only within the current
1483 target's context. Otherwise we lose all but the last value if the
1484 variable is appended more than once within the current target
1485 context. Fixes PR/1831.
1487 2000-08-16 Paul D. Smith <psmith@gnu.org>
1489 * function.c (func_shell): Nul-terminate the buffer before
1490 printing an exec error message (just in case it's not!).
1491 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
1493 2000-07-25 Paul D. Smith <psmith@gnu.org>
1495 * job.c (construct_command_argv_internal): Add "~" to the list of
1496 sh_chars[] which disallow optimizing out the shell call.
1498 2000-07-23 Paul Eggert <eggert@twinsun.com>
1500 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
1501 supersedes --disable-nsec-timestamps.
1502 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
1503 * README: Remove --disable-nsec-timestamps.
1505 * filedef.h (struct file.low_resolution_time): New member.
1506 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
1507 * remake.c (update_file_1):
1508 Avoid spurious rebuilds due to low resolution time stamps,
1509 generalizing the earlier code that applied only to archive members.
1510 (f_mtime): Archive members always have low resolution time stamps.
1512 * configure.in: Remove --disable-nsec-timestamps, as this has
1513 been superseded by .LOW_RESOLUTION_TIME.
1515 2000-07-23 Paul Eggert <eggert@twinsun.com>
1517 * configure.in (enable_nsec_timestamps): Renamed from
1518 make_cv_nsec_timestamps, since enable/disable options
1519 shouldn't be cached.
1521 2000-07-23 Bruno Haible <haible@clisp.cons.org>
1522 and Paul Eggert <eggert@twinsun.com>
1524 * file.c (file_timestamp_now):
1525 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
1526 so that clock_gettime is not linked unless needed.
1528 * filedef.h (FILE_TIMESTAMP_HI_RES):
1529 Remove definition; "configure" now does this.
1531 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
1532 to before high resolution file timestamp check,
1533 since that check now uses uintmax_t.
1534 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
1535 high resolution file timestamps.
1536 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
1537 so that we don't link in clock_gettime unnecessarily.
1539 2000-07-17 Paul D. Smith <psmith@gnu.org>
1541 * i18n/ja.po: New version of the translation file.
1543 2000-07-07 Paul D. Smith <psmith@gnu.org>
1545 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
1546 the offset calculation.
1547 (name_mtime): Replace EINTR test with EINTR_SET macro.
1549 2000-07-07 Paul Eggert <eggert@twinsun.com>
1553 * remake.c (update_file_1):
1554 Avoid spurious rebuilds of archive members due to their
1555 timestamp resolution being only one second.
1556 (f_mtime): Avoid spurious warnings of timestamps in the future due to
1557 the clock's resolution being lower than file timestamps'.
1558 When warning about future timestamps, report only the discrepancy,
1559 not the absolute value of the timestamp and the current time.
1561 * file.c (file_timestamp_now): New arg RESOLUTION.
1562 * filedef.h (file_timestamp_now): Likewise.
1563 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
1565 2000-07-05 Paul D. Smith <psmith@gnu.org>
1567 * variable.c (lookup_variable) [VMS]: Remove vestigial references
1568 to listp. Fixes PR/1793.
1570 2000-06-26 Paul Eggert <eggert@twinsun.com>
1572 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
1574 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
1576 * remake.c (f_mtime): Remove unused var memtime.
1578 2000-06-25 Martin Buchholz <martin@xemacs.org>
1580 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
1581 Ran spell-check on make.texinfo.
1583 2000-06-23 Paul D. Smith <psmith@gnu.org>
1585 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
1586 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
1587 * make.h: Define these macros.
1589 * Version 3.79.1 released.
1591 * configure.in: Add a new option, --disable-nsec-timestamps, to
1592 avoid using sub-second timestamps on systems that support it. It
1593 can lead to problems, e.g. if your makefile relies on "cp -p".
1594 * README.template: Document the issue with "cp -p".
1596 * config.guess, config.sub: Updated.
