3 Implement "if... else if... endif" syntax.
4
5 * read.c (eval): Push all checks for conditional words ("ifeq",
6 "else", etc.) down into the conditional_line() function.
7 (conditional_line): Rework to allow "else if..." clause. New
8 return value -2 for lines which are not conditionals. The
9 ignoring flag can now also be 2, which means "already parsed a
10 true branch". If that value is seen no other branch of this
11 conditional can be considered true. In the else parsing if there
12 is extra text after the else, invoke conditional_line()
13 recursively to see if it's another conditional. If not, it's an
14 error. If so, raise the conditional value to this level instead
15 of creating a new conditional nesting level. Special check for
16 "else" and "endif", which aren't allowed on the "else" line.
17 * doc/make.texi (Conditional Syntax): Document the new syntax.
18
192005-05-09 Paul D. Smith <psmith@gnu.org>
20
21 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
22 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
23 recurses to the w32 directory, even on non-Windows systems. Use
24 the method suggested in the automake manual.
25 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
26 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
27
282005-05-07 Paul D. Smith <psmith@gnu.org>
29
30 * main.c (die): If we're dying with a fatal error (not that a
31 command has failed), write back any leftover tokens before we go.
32
33 * job.c (set_child_handler_action_flags): If there are jobs
34 waiting for the load to go down, set an alarm to go off in 1
35 second. This allows us to wake up from a potentially long-lasting
36 read() and start a new job if the load has gone down. Turn it off
37 after the read.
38 (job_noop): Dummy signal handler function.
39 (new_job): Invoke it with the new semantics.
40
41 * docs/make.texi: Document secondary expansion. Various cleanups
42 and random work.
43
442005-05-03 Paul D. Smith <psmith@gnu.org>
45
46 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
47 the targets which are to ultimately be made are called "goals";
48 see the GNU make manual. Also, MAKECMDGOALS, etc.
49
50 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
51 .DEFAULT_GOAL, and default_target_name to default_goal_name.
52 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
53
542005-05-02 Paul D. Smith <psmith@gnu.org>
55
56 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
57 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
58 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
59 functions to vmsjobs.c. #include it into jobs.c.
60
61 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
62 jobserver tokens. I found that this happens when an exported
63 recursive variable contains a $(shell ...) function reference: in
64 this situation we could "forget" to write back a token.
65
66 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
67 we have. It's not reliable to depend on the number of children in
68 our linked list so keep a separate count.
69 (new_job): Check jobserver_tokens rather than children &&
70 waiting_jobs. Increment jobserver_tokens when we get one.
71 (free_child): If jobserver_tokens is 0, internal error. If it's
72 >1, write a token back to the jobserver pipe (we don't write a
73 token for the "free" job). Decrement jobserver_tokens.
74
75 * main.c: Add variable master_job_slots.
76 (main): Set it to hold the number of jobs requested if we're the
77 master process, when using the jobserver.
78 (die): Sanity checks: first test jobserver_tokens to make sure
79 this process isn't holding any tokens we didn't write back.
80 Second, if master_job_slots is set count the tokens left in the
81 jobserver pipe and ensure it's the same as master_job_slots (- 1).
82
832005-04-24 Paul D. Smith <psmith@gnu.org>
84
85 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
86 with -l# can lose jobserver tokens, because waiting jobs are not
87 consulted properly when checking for the "free" token.
88
89 * job.c (free_child): Count waiting_jobs as having tokens.
90 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
91 handle jobs waiting for the load to drop.
92
932005-04-23 Paul D. Smith <psmith@gnu.org>
94
95 * main.c (main): Be careful to not core if a variable setting in
96 the environment doesn't contain an '='. This is illegal but can
97 happen in broken setups.
98 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.

1002005-04-12 Paul D. Smith <psmith@gnu.org>
101
102 The second expansion feature causes significant slowdown. Timing
103 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
104 read the makefile before the feature, to 11+s to do the same
105 operations after the feature. Additionally, memory usage
106 increased drastically. To fix this I added some intelligence that
107 avoids the overhead of the second expansion unless it's required.
108
109 * dep.h: Add a new boolean field, need_2nd_expansion.
110
111 * read.c (eval): When creating the struct dep for the target,
112 check if the name contains a "$"; if so set need_2nd_expansion to 1.
113 (record_files): If there's a "%" in a static pattern rule, it gets
114 converted to "$*" so set need_2nd_expansion to 1.
115
116 * file.c (expand_deps): Rework to be more efficient. Only perform
117 initialize_file_variables(), set_file_variables(), and
118 variable_expand_for_file() if the need_2nd_expansion is set.
119
120 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
121 (pattern_search): Ditto.
122 * main.c (handle_non_switch_argument): Ditto.
123 (main): Ditto.
124 * read.c (read_all_makefiles): Ditto.
125 (eval_makefile): Ditto.
126
1272005-04-07 Paul D. Smith <psmith@gnu.org>
128
129 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
130 * variable.c (sync_Path_environment): Ditto.
131 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
132
133 * main.c (main): Define the .FEATURES variable.
134 * NEWS: Announce .FEATURES.
135 * doc/make.texi (Special Variables): Document .FEATURES.
136
137 * remake.c (check_dep): If a file is .PHONY, update it even if
138 it's marked intermediate. Fixes Savannah bug #12331.
139
1402005-03-15 Boris Kolpackov <boris@kolpackov.net>
141
142 * file.c (expand_deps): Factor out the second expansion and
143 prerequisite line parsing logic from snap_deps().
144
145 * file.c (snap_deps): Use expand_deps(). Expand and parse
146 prerequisites of the .SUFFIXES special target first. Fixes
147 Savannah bug #12320.
148
1492005-03-13 Paul D. Smith <psmith@gnu.org>
150
151 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
152 Zaretskii.
153
1542005-03-11 Paul D. Smith <psmith@gnu.org>
155
156 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
157 available, not undefined (from Earnie Boyd).
158
1592005-03-10 Boris Kolpackov <boris@kolpackov.net>
160
161 * implicit.c (pattern_search): Mark an intermediate target as
162 precious if it happened to be a prerequisite of some (other)
163 target. Fixes Savannah bug #12267.
164
1652005-03-09 Paul D. Smith <psmith@gnu.org>
166
167 * read.c (eval_makefile): Add alloca(0).
168 (eval_buffer): Ditto.
169
1702005-03-09 Boris Kolpackov <boris@kolpackov.net>
171
172 * main.c (main): Use o_file instead of o_default when defining
173 the .DEFAULT_TARGET special variable.
174 * read.c (eval): Use define_variable_global() instead of
175 define_variable() when setting new value for the .DEFAULT_TARGET
176 special variable. Fixes Savannah bug #12266.
177
1782005-03-04 Boris Kolpackov <boris@kolpackov.net>
179
180 * imlicit.c (pattern_search): Mark files for which an implicit
181 rule has been found as targets. Fixes Savannah bug #12202.
182
1832005-03-04 Paul D. Smith <psmith@gnu.org>
184
185 * AUTHORS: Update.
186 * doc/make.texi (Automatic Variables): Document $|.
187
1882005-03-03 Boris Kolpackov <boris@kolpackov.net>
189
190 * read.c (record_files): Instead of substituting % with
191 actual stem value in dependency list replace it with $*.
192 This fixes stem triple expansion bug.
193
194 * implicit.c (pattern_search): Copy stem to a separate
195 buffer and make it a properly terminated string. Assign
196 this buffer instead of STEM (which is not terminated) to
197 f->stem. Instead of substituting % with actual stem value
198 in dependency list replace it with $*. This fixes stem
199 triple expansion bug.
200
2012005-03-01 Paul D. Smith <psmith@gnu.org>
202
203 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
204 on Windows, as it takes a handle not a pid. Just exit.
205 Fix from patch #3679, provided by Alessandro Vesely.
206
207 * configure.in: Update check for sys_siglist[] from autoconf manual.
208 * signame.c (strsignal): Update to use the new autoconf macro.
209
2102005-03-01 Boris Kolpackov <boris@kolpackov.net>
211
212 * read.c (record_files): Add a check for the list of prerequisites
213 of a static pattern rule being empty. Fixes Savannah bug #12180.
214
2152005-02-28 Paul D. Smith <psmith@gnu.org>
216
217 * doc/make.texi (Text Functions): Update docs to allow the end
218 ordinal for $(wordlist ...) to be 0.
219 * function.c (func_wordlist): Fail if the start ordinal for
220 $(wordlist ...) is <1. Matches documentation.
221 Resolves Savannah support request #103195.
222
223 * remake.c (update_goal_chain): Fix logic for stopping in -q:
224 previously we were stopping when !-q, exactly the opposite. This
225 has been wrong since version 1.34, in 1994!
226 (update_file): If we got an error don't break out to run more
227 double-colon rules: just return immediately.
228 Fixes Savannah bug #7144.
229
2302005-02-27 Paul D. Smith <psmith@gnu.org>
231
232 * misc.c (end_of_token): Make argument const.
233 * make.h: Update prototype.
234
235 * function.c (abspath, func_realpath, func_abspath): Use
236 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
237 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
238 * read.c (record_files): Ditto.
239 * variable.c (do_variable_definition): Ditto.
240
241 * function.c (func_error): Create a new function $(info ...) that
242 simply prints the message to stdout with no extras.
243 (function_table_init): Add new function to the table.
244 * NEWS: Add $(info ...) reference.
245 * doc/make.texi (Make Control Functions): Document it.
246
247 New feature: if the system supports symbolic links, and the user
248 provides the -L/--check-symlink-time flag, then use the latest
249 mtime between the symlink(s) and the target file.
250
251 * configure.in (MAKE_SYMLINKS): Check for lstat() and
252 readlink(). If both are available, define MAKE_SYMLINKS.
253 * main.c: New variable: check_symlink_flag.
254 (usage): Add a line for -L/--check-symlink-times to the help string.
255 (switches): Add -L/--check-symlink-times command line argument.
256 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
257 print a warning and disable it again.
258 * make.h: Declare check_symlink_flag.
259 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
260 if the file is a symlink then check each link in the chain and
261 choose the NEWEST mtime we find as the mtime for the file. The
262 newest mtime might be the file itself!
263 * NEWS: Add information about this new feature.
264 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
265
266 Avoid core dumps described in Savannah bug # 12124:
267
268 * file.c: New variable snapped_deps remember whether we've run
269 snap_deps().
270 (snap_deps): Set it.
271 * filedef.h: Extern it.
272 * read.c (record_files): Check snapped_deps; if it's set then
273 we're trying to eval a new target/prerequisite relationship from
274 within a command script, which we don't support. Fatal.
275
2762005-02-28 Boris Kolpackov <boris@kolpackov.net>
277
278 Implementation of the .DEFAULT_TARGET special variable.
279
280 * read.c (eval): If necessary, update default_target_name when
281 reading rules.
282 * read.c (record_files): Update default_target_file if
283 default_target_name has changed.
284 * main.c (default_target_name): Define.
285 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
286 default_target_name is set use default_target_file as a root
287 target to make.
288 * filedef.h (default_target_name): Declare.
289 * dep.h (free_dep_chain):
290 * misc.c (free_dep_chain): Change to operate on struct nameseq
291 and change name to free_ns_chain.
292 * file.c (snap_deps): Update to use free_ns_chain.
293
2942005-02-27 Boris Kolpackov <boris@kolpackov.net>
295
296 Implementation of the second expansion in explicit rules,
297 static pattern rules and implicit rules.
298
299 * read.c (eval): Refrain from chopping up rule's dependencies.
300 Store them in a struct dep as a single dependency line. Remove
301 the code that implements SySV-style automatic variables.
302
303 * read.c (record_files): Adjust the code that handles static
304 pattern rules to expand all percents instead of only the first
305 one. Reverse the order in which dependencies are stored so that
306 when the second expansion reverses them again they appear in
307 the makefile order (with some exceptions, see comments in
308 the code). Remove the code that implements SySV-style automatic
309 variables.
310
311 * file.c (snap_deps): Implement the second expansion and chopping
312 of dependency lines for explicit rules.
313
314 * implicit.c (struct idep): Define an auxiliary data type to hold
315 implicit rule's dependencies after stem substitution and
316 expansion.
317
318 * implicit.c (free_idep_chain): Implement.
319
320 * implicit.c (get_next_word): Implement helper function for
321 parsing implicit rule's dependency lines into words taking
322 into account variable expansion requests. Used in the stem
323 splitting code.
324
325 * implicit.c (pattern_search): Implement the second expansion
326 for implicit rules. Also fixes bug #12091.
327
328 * commands.h (set_file_variables): Declare.
329 * commands.c (set_file_variables): Remove static specifier.
330
331 * dep.h (free_dep_chain): Declare.
332 * misc.c (free_dep_chain): Implement.
333
334 * variable.h (variable_expand_for_file): Declare.
335 * expand.c (variable_expand_for_file): Remove static specifier.
336
337 * make.h (strip_whitespace): Declare.
338 * function.c (strip_whitespace): Remove static specifier.
339
3402005-02-26 Paul D. Smith <psmith@gnu.org>
341
342 * main.c (main): Check for ferror() when reading makefiles from stdin.
343 Apparently some shells in Windows don't close pipes properly and
344 require this check.
345
3462005-02-24 Jonathan Grant <jg@jguk.org>
347
348 * configure.in: Add MinGW configuration options, and extra w32 code
349 directory.
350 * Makefile.am: Add MinGW configuration options, and extra w32 code
351 directory.
352 * main.c: Determine correct program string (after last \ without .exe).
353 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
354 type fix x2
355 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
356 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
357 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
358 environment support.
359
3602004-04-16 Dmitry V. Levin <ldv@altlinux.org>
361
362 * function.c (func_shell): When initializing error_prefix, check
363 that reading file name is not null. This fixes long-standing
364 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
365
3662005-02-09 Paul D. Smith <psmith@gnu.org>
367
368 * maintMakefile: Update the CVS download URL to simplify them.
369 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
370 downloading the .texi files from Savannah now.
371
372 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
373
374 * main.c (handle_non_switch_argument): Only add variables to
375 command_variables if they're not already there: duplicate settings
376 waste space and can be confusing to read.
377
378 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
379 this header is never included by non-WINDOWS32 code, and it
380 requires <config.h> to define which isn't always included first.
381
382 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
383 testing MINGW32 versions.
384
385 * main.c (log_working_directory): flush stdout to be sure the WD
386 change is printed before any stderr messages show up.
387
3882005-02-01 Paul D. Smith <psmith@gnu.org>
389
390 * maintMakefile (po_repo): Update the GNU translation site URL.
391
3922004-12-01 Paul D. Smith <psmith@gnu.org>
393
394 * main.c (main): Change char* env_shell to struct variable shell_var.
395 * variable.c (target_environment): Use new shell_var.
396
3972004-11-30 Paul D. Smith <psmith@gnu.org>
398
399 * configure.in: The old way we avoided creating build.sh from
400 build.sh.in before build.sh.in exists doesn't work anymore; we
401 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
402 the help!). This also keeps automake from complaining.
403 * Makefile.am (README): Add a dummy target so automake won't
404 complain that this file doesn't exist when we checkout from CVS.
405 * maintMakefile (.dep_segment): Rewrite this rule since newer
406 versions of automake don't provide DEP_FILES.
407
4082004-11-30 Boris Kolpackov <boris@kolpackov.net>
409
410 Implementation of `realpath' and `abspath' built-in functions.
411
412 * configure.in: Check for realpath.
413 * function.c (abspath): Return an absolute file name that does
414 not contain any `.' or `..' components, nor repeated `/'.
415 * function.c (func_abspath): For each name call abspath.
416 * function.c (func_realpath): For each name call realpath
417 from libc or delegate to abspath if realpath is not available.
418 * doc/make.texi (Functions for File Names): Document new functions.
419 * doc/make.texi (Quick Reference): Ditto.
420
4212004-11-28 Paul D. Smith <psmith@gnu.org>
422
423 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
424 arguments. Fixes bug #10252.
425
426 Fix for bug #1276: Handle SHELL according to POSIX requirements.
427
428 * main.c (main): Set SHELL to v_noexport by default. Remember the
429 original environment setting of SHELL in the env_shell variable.
430 * main.h: Export new env_shell variable.
431 * variable.c (target_environment): If we find a v_noexport
432 variable for SHELL, add a SHELL variable with the env_shell value.
433 * doc/make.texi (Quick Reference): Document the POSIX behavior.
434 * doc/make.texi (Variables/Recursion): Ditto.
435
4362004-11-28 Paul D. Smith <psmith@gnu.org>
437
438 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
439 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
440 Patch by Alessandro Vesely.
441
4422004-11-12 Paul D. Smith <psmith@gnu.org>
443
444 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
445 the command line if it's inside a string.
446 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
447
4482004-10-21 Boris Kolpackov <boris@kolpackov.net>
449
450 * function.c (func_lastword): New function: return last word
451 from the list of words.
452 * doc/make.texi: Document $(lastword ). Fix broken links in
453 Quick Reference section.
454
4552004-10-06 Paul D. Smith <psmith@gnu.org>
456
457 Apply patch from Alessandro Vesely, provided with bug # 9748.
458 Fix use of tmpnam() to work with Borland C.
459
460 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
461 construction of a temporary filename, and call new function
462 create_batch_filename().
463 (create_batch_filename) [WINDOWS32]: New function to create a
464 temporary filename.
465
4662004-10-05 Boris Kolpackov <boris@kolpackov.net>
467
468 * read.c (record_target_var): Expand simple pattern-specific
469 variable.
470 * variable.c (initialize_file_variables): Do not expand simple
471 pattern-specific variable.
472
4732004-09-28 Boris Kolpackov <boris@kolpackov.net>
474
475 * remake.c (update_file_1): When rebuilding makefiles inherit
476 dontcare flag from a target that triggered update.
477
4782004-09-27 Boris Kolpackov <boris@kolpackov.net>
479
480 * variable.c (initialize_file_variables): Mark pattern-specific
481 variable as a per-target and copy export status.
482
4832004-09-21 Boris Kolpackov <boris@kolpackov.net>
484
485 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
486
487 * implicit.c (pattern_search): When considering an implicit rule's
488 prerequisite check that it is actually a target rather then
489 just an entry in the file hashtable.
490
4912004-09-21 Paul D. Smith <psmith@gnu.org>
492
493 * read.c (readstring): Fix some logic errors in backslash handling.
494 (eval): Remove some unnecessary processing in buffer handling.
495 (record_target_var): Assert that parse_variable_definition() succeeded.
496 Reported by: Markus Mauhart <qwe123@chello.at>.
497
498 * misc.c: Removed the sindex() function. All instances of this
499 function were trivially replaceable by the standard strstr()
500 function, and that function will always have better (or certainly
501 no worse) performance than the very simple-minded algorithm
502 sindex() used. This can matter with complex makefiles.
503 * make.h: Remove the prototype for sindex().
504 * function.c (subst_expand): Convert sindex() call to strstr().
505 This means we no longer need to track the TLEN value so remove that.
506 (func_findstring): Convert sindex() to strstr().
507 * commands.c (chop_commands): Convert sindex() calls to strstr().
508 Suggested by: Markus Mauhart <qwe123@chello.at>.
509
510 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
511 idea behind Savannah Patch #3144 from david.baird@homemail.com.
512 If SHELL is set to CMD.EXE then assume it's batch-mode and
513 non-unixy. I wrote the code differently from the patch, though,
514 to make it safer. This also resolves bug #9174.
515
5162004-09-20 Paul D. Smith <psmith@gnu.org>
517
518 * expand.c (variable_expand_string): Modify to invoke
519 patsubst_expand() instead of subst_expand(); the latter didn't
520 handle suffix patterns correctly.
521 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
522 was used only from variable_expand_string() and is no longer used
523 there.
524 (func_subst): Ditto, on call to subst_expand().
525 (patsubst_expand): Require the percent pointers to point to the
526 character after the %, not to the % itself.
527 * read.c (record_files): New call criteria for patsubst_expand().
528 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
529 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
530
5312004-09-19 Paul D. Smith <psmith@gnu.org>
532
533 * function.c (subst_expand): Fix a check in by_word: look for a
534 previous blank if we're beyond the beginning of the string, not
535 the beginning of the word.
536 Bugs reported by Markus Mauhart <qwe123@chello.at>.
537
5382004-05-16 Paul D. Smith <psmith@gnu.org>
539
540 * remake.c (update_goal_chain): Change the argument specifying
541 whether we're rebuilding makefiles to be a global variable,
542 REBUILDING_MAKEFILES.
543 (complain): Extract the code that complains about no rules to make
544 a target into a separate function.
545 (update_file_1): If we tried to rebuild a file during the makefile
546 rebuild phase and it was dontcare, then no message was printed.
547 If we then try to build the same file during the normal build,
548 print a message this time.
549 (remake_file): Don't complain about un-remake-able files when
550 we're rebuilding makefiles.
551
5522004-05-11 Paul D. Smith <psmith@gnu.org>
553
554 * job.c (construct_command_argv_internal): OS/2 patches from
555 Andreas Buening <andreas.buening@nexgo.de>.
556
5572004-05-10 Paul D. Smith <psmith@gnu.org>
558
559 * remake.c (update_file): Don't walk the double-colon chain unless
560 this is a double-colon rule. Fix suggested by Boris Kolpackov
561 <boris@kolpackov.net>.
562
563 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
564 * readme.vms: New section describing OpenVMS support and issues.
565 * default.c (default_variables): Add support for IA64.
566 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
567 without some privilege aborts make with the error
568 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
569 pressing Ctrl+Y and the input device is no terminal. The change
570 catches this error and just continues.
571
572 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
573
5742004-04-25 Paul D. Smith <psmith@gnu.org>
575
576 * commands.c (set_file_variables): Set $< properly in the face of
577 order-only prerequisites.
578 Patch from Boris Kolpackov <boris@kolpackov.net>
579
5802004-04-21 Bob Byrnes <byrnes@curl.com>
581
582 * main.c (main): Notice failures to remake makefiles.
583
5842004-03-28 Paul D. Smith <psmith@gnu.org>
585
586 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
587
588 * job.c: No default shell for RISC OS.
589 (load_too_high): Hard-code the return to 1.
590 (construct_command_argv_internal): No sh_chars or sh_cmds.
591 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
592
5932004-03-20 Paul D. Smith <psmith@gnu.org>
594
595 * variable.c (do_variable_definition): Don't append from the
596 global set if a previous non-appending target-specific variable
597 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
598 (with fix).
599
600 * expand.c (reference_variable): Don't give up on variables with
601 no value that have the target-specific append flag set: they might
602 have a value after all. Reported by Oliver Schmidt
603 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
604 <nikulin@dx1cmd.inp.nsk.su>.
605
606 * rule.c (count_implicit_rule_limits): Don't delete patterns which
607 refer to absolute pathnames in directories that don't exist: some
608 portion of the makefile could create those directories before we
609 match the pattern. Fixes bugs #775 and #108.
610
611 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
612
613 * main.c (main): Free makefile_mtimes if we have any.
614 * README.W32.template: Update documentation for the current status
615 of the MS-Windows port.
616 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
617 environment variable is sometimes already defined which causes the
618 build to fail.
619 * main.c (debug_signal_handler): Only define this function if
620 SIGUSR1 is available.
621
622 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
623
624 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
625 * README.OS2.template: Documentation updates.
626 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
627 link line for safety.
628 * maintMakefile (build.sh.in): Remove an extraneous ")".
629 * job.c (child_execute_job): Close saved FDs.
630 * job.c (exec_command) [OS/2]: exec_command(): If the command
631 can't be exec'ed and if the shell is not Unix-sh, then try again
632 with argv = { "cmd", "/c", ... }. Normally, this code is never
633 reached for the cmd shell unless the command really doesn't exist.
634 (construct_command_argv_internal) [OS/2]: The code for cmd
635 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
636 The CMD builtin commands are case insensitive so use strcasecmp().
637
6382004-03-19 Paul D. Smith <psmith@gnu.org>
639
640 * read.c (do_define): Re-order line counter increment so the count
641 is accurate (we were losing one line per define). Reported by
642 Dave Yost <Dave@Yost.com>.
643
6442004-03-06 Paul D. Smith <psmith@gnu.org>
645
646 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
647 compiler.
648 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
649 * misc.c (message,error,fatal): Ditto.
650 * configh.dos.template: Define HAVE_ANSI_COMPILER.
651 * config.h.W32.template: Ditto.
652 * config.h-vms.template: Ditto.
653 * config.ami.template: Ditto.
654
6552004-03-04 Paul D. Smith <psmith@gnu.org>
656
657 * README.template: Add a note about broken /bin/sh on SunOS
658 4.1.3_U1 & 4.1.4. Fix up Savannah links.
659
660 * misc.c (message, error, fatal): Don't use "..." if we're using
661 varargs. ansi2knr should handle this but it doesn't work: it
662 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
663 done. On many systems (SunOS for example) va_dcl is a #define.
664 So, force the use of the non-"..." version on pre-ANSI compilers.
665
666 * maintMakefile (sign-dist): Create some rules to help automate
667 the new GNU ftp upload method.
668
6692004-02-24 Paul D. Smith <psmith@gnu.org>
670
671 * config.h.W32.template: Add HAVE_STDARG_H
672 * config.h-vms.template: Ditto.
673 * config.ami.template: Ditto.
674
6752004-02-23 Jonathan Grant <jg-make@jguk.org>
676
677 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
678 * build_w32.bat: Remove extra "+".
679
6802004-02-23 Paul D. Smith <psmith@gnu.org>
681
682 * make.h: Create an UNUSED macro to mark unused parameters.
683 * (many): Clean up warnings by applying UNUSED, fixing
684 signed/unsigned incompatibilities, etc.
685
686 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
687 autoconf warnings.
688 * filedef.h: Name the command_state enumeration.
689 * file.c (set_command_state): Use the enumeration in the function
690 argument.
691
692 * configure.in: Explicitly set SET_MAKE to empty, to disable
693 MAKE=make even when no make already exists. Fix bug #3823.
694
6952004-02-22 Paul D. Smith <psmith@gnu.org>
696
697 * maintMakefile: Perl script to clean up all non-CVS files. Use
698 it on all the subdirectories for the cvs-clean target.
699
700 * main.c (decode_switches): Require non-empty strings for all our
701 string command-line options. Fixes Debian bug # 164165.
702
703 * configure.in: Check for stdarg.h and varargs.h.
704 * make.h (USE_VARIADIC): Set this if we can use variadic functions
705 for printing messages.
706 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
707 (message): Ditto.
708 (error): Ditto.
709 (fatal): Ditto.
710
711 A number of patches for OS/2 support from Andreas Buening
712 <andreas.buening@nexgo.de>:
713
714 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
715 disable the SIGCHLD handler.
716 (reap_children) [OS/2]: Remove special handling of job_rfd.
717 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
718 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
719 * main.c (main) [OS/2]: Special handling for paths in OS/2.
720 * configure.in [OS/2]: Force SA_RESTART for OS/2.
721 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
722 systems.
723
7242004-02-21 Paul D. Smith <psmith@gnu.org>
725
726 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
727 <mail@kristov.de> reports that if process_begin() fails we don't
728 handle the error condition correctly in all cases.
729 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
730 to have a newline on the message.
731
732 * job.c (construct_command_argv_internal): Add "test" to UNIX
733 sh_cmds[]. Fixes Savannah bug # 7606.
734
7352004-02-04 Paul D. Smith <psmith@gnu.org>
736
737 * job.c (vms_handle_apos) [VMS]: Fix various string handling
738 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
739 Hartmut Becker <Hartmut.Becker@hp.com>.
740
7412004-01-21 Paul D. Smith <psmith@gnu.org>
742
743 * job.c (load_too_high): Implement an algorithm to control the
744 "thundering herd" problem when using -l to control job creation
745 via the load average. The system only recomputes the load once a
746 second but we can start many jobs in a second. To solve this we
747 keep track of the number of jobs started in the last second and
748 apply a weight to try to guess what a correct load would be.
749 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
750 Also fixes bug #4693.
751 (reap_children): Decrease the job count for this second.
752 (start_job_command): Increase the job count for this second.
753
754 * read.c (conditional_line): Expand the text after ifn?def before
755 checking to see if it's a single word. Fixes bug #7257.
756
7572004-01-09 Paul D. Smith <psmith@gnu.org>
758
759 * file.c (print_file): Recurse to print all targets in
760 double-colon rules. Fixes bug #4518, reported (with patch) by
761 Andrew Chatham <chatham@google.com>.
762
7632004-01-07 Paul D. Smith <psmith@gnu.org>
764
765 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
766 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
767 AC_FUNC_SETVBUF_REVERSED.
768
769 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
770 (MAKE Variable): Fix Savannah bug #4898.
771
772 * job.c (construct_command_argv_internal): Add "!" to the list of
773 shell escape chars. POSIX sh allows it to appear before a
774 command, to negate the exit code. Fixes bug #6404.
775
776 * implicit.c (pattern_search): When matching an implicit rule,
777 remember which dependencies have the ignore_mtime flag set.
778 Original fix provided in Savannah patch #2349, by Benoit
779 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
780
7812003-11-22 Paul D. Smith <psmith@gnu.org>
782
783 * README.W32.template (Outputs): Clarification on -j with
784 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
785 <jg-make@jguk.org>.
786
7872003-11-02 Paul D. Smith <psmith@gnu.org>
788
789 * function.c (func_if): Strip all the trailing whitespace from the
790 condition, then don't expand it. Fixed bug # 5798.
791
792 * expand.c (recursively_expand_for_file): If we're expanding a
793 variable with no file context, then use the variable's context.
794 Fixes bug # 6195.
795
7962003-10-21 Paul D. Smith <psmith@gnu.org>
797
798 * main.c (log_working_directory): Add newlines to printf()s.
799
800 * README.cvs: Add a note to ignore warnings during autoreconf.
801
802 * maintMakefile (po_repo): Set a new URL for PO file updates.
803 (get-config/config.guess get-config/config.sub): Get these files
804 from the Savannah config project instead of ftp.gnu.org.
805
8062003-10-05 Paul Eggert <eggert@twinsun.com>
807
808 * main.c (main): Avoid potential subscript error if environ has
809 short strings.
810
8112003-08-22 Paul D. Smith <psmith@gnu.org>
812
813 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
814 systems which don't yet implement the C89 standard :-/.
815
8162003-07-18 Paul D. Smith <psmith@gnu.org>
817
818 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
819 [WINDOWS32]: Initialize hash.
820
8212003-06-19 Earnie Boyd <earnie@uses.sf.net>
822
823 * dir.c (read_dirstream): Provide a workaround for broken versions of
824 the MinGW dirent structure.
825
8262003-05-30 Earnie Boyd <earnie@users.sf.net>
827
828 * w32/include/dirent.h: Add __MINGW32__ filter.
829
8302003-05-30 Earnie Boyd <earnie@users.sf.net>
831
832 * make.h: Add global declaration of *make_host.
833 * main.c (print_usage): Remove local declaration of *make_host.
834 (print_version): Display "This program built for ..." after Copyright
835 notice.
836
8372003-05-30 Earnie Boyd <earnie@users.sf.net>
838
839 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
840 execution of "makeinfo --html make.texi".
841
8422003-04-30 Paul D. Smith <psmith@gnu.org>
843
844 * build.template: Make some changes to maybe allow this script to
845 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
846
847 * README.OS2.template: New file for OS/2 support. Original
848 contributed by Andreas Buening.
849 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
850 DOS-style paths.
851
8522003-04-19 Paul D. Smith <psmith@gnu.org>
853
854 Fix bug #1405: allow a target to match multiple pattern-specific
855 variables.
856
857 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
858 variable.c, where they've always belonged.
859 * rule.h: Move the prototypes and struct pattern_var as well.
860 * variable.c (initialize_file_variables): Invoke
861 lookup_pattern_var() in a loop, until no more matches are found.
862 If a match is found, create a new variable set for the target's
863 pattern variables. Then merge the contents of each matching
864 pattern variable set into the target's pattern variable set.
865 (lookup_pattern_var): Change this function to be usable
866 in a loop. It takes a starting position: if NULL, start at the
867 beginning; if non-NULL, start with the pattern variable after that
868 position, and return the next matching pattern.
869 (create_pattern_var): Create a unique instance of
870 pattern-specific variables for every definition in the makefile.
871 Don't combine the same pattern together. This allows us to
872 process the variable handling properly even when the same pattern
873 is used multiple times.
874 (parse_variable_definition): New function: break out the parsing
875 of a variable definition line from try_variable_definition.
876 (try_variable_definition): Call parse_variable_definition to
877 parse.
878 (print_variable_data_base): Print out pattern-specific variables.
879 * variable.h (struct variable): Remember when a variable is
880 conditional. Also remember its flavor.
881 (struct pattern_var): Instead of keeping a variable set, we just
882 keep a single variable for each pattern.
883 * read.c (record_target_var): Each pattern variable contains only a
884 single variable, not a set, so create it properly.
885 * doc/make.texi (Pattern-specific): Document the new behavior.
886
8872003-04-17 Paul D. Smith <psmith@gnu.org>
888
889 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
890 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
891 file/directory naming rules for VMS so I can't tell whether this
892 is correct or not.
893
8942003-04-09 Paul D. Smith <psmith@gnu.org>
895
896 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
897 DOS-style pathnames: backslash separators and drive specifiers.
898
8992003-03-28 Paul D. Smith <psmith@gnu.org>
900
901 * file.c (snap_deps): If .SECONDARY with no targets is given, set
902 the intermediate flag on all targets. Fixes bug #2515.
903
9042003-03-24 Paul D. Smith <psmith@gnu.org>
905
906 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
907 Upgrade to autoconf 2.57 and automake 1.7.3.
908
909 * job.c: More OS/2 changes from Andreas Buening.
910
911 * file.c (print_file): Fix variable initialization.
912 Fixes bug #2892.
913
914 * remake.c (notice_finished_file):
915
916 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
917 some calls (like readdir()) return NULL in valid situations
918 without resetting errno. Fixes bug #2846.
919
9202003-02-25 Paul D. Smith <psmith@gnu.org>
921
922 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
923
924 * job.c (_is_unixy_shell) [OS/2]: New function.
925 Set default shell to /bin/sh.
926 (reap_children): Close the job_rfd pipe here since we don't use a
927 SIGCHLD handler.
928 (set_child_handler_action_flags): define this to empty on OS/2.
929 (start_job_command): Close the jobserver pipe and use
930 child_execute_job() instead of fork/exec.
931 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
932 rather than exec'ing, then reconfigure stdin/stdout.
933 (exec_command): Rewrite to use spawn instead of exec. Return the
934 PID of the child.
935
936 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
937 in DOS. Handle the TEMP environment variable as in DOS. Don't
938 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
939 use -j in DOS mode. Use child_execute_job() instead of
940 exec_command().
941
942 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
943 spawn() instead.
944
945 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
946 prototypes that return values.
947
948 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
949
950 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
951 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
952 for OS/2.
953 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
954 DOS paths.
955
9562003-02-24 Paul D. Smith <psmith@gnu.org>
957
958 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
959 * job.c (child_execute_job) [VMS]: New code for handling spawn().
960 (child_execute_job) [VMS]: Handle error status properly.
961 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
962
963 * function.c (func_shell): Use EINTRLOOP() while reading from the
964 subshell pipe (Fixes bug #2502).
965 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
966 jobserver pipe.
967 * main.c (main): Ditto.
968
9692003-01-30 Paul D. Smith <psmith@gnu.org>
970
971 * read.c (eval): eval() was not fully reentrant, because the
972 collapsed buffer was static. Change it to be an automatic
973 variable so that eval() can be invoked recursively.
974 Fixes bug # 2238.
975 (eval): Apply patch # 1022: fix memory reference error on long
976 target-specific variable lines.
977 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
978
979 * function.c (check_numeric): Combine the is_numeric() function
980 into this function, since it's only called from one place.
981 Constify this function. Have it print the incorrect string in the
982 error message. Fixes bug #2407.
983 (strip_whitespace): Constify.
984 (func_if): Constify.
985 * expand.c (expand_argument): Constify.
986
9872003-01-29 Paul D. Smith <psmith@gnu.org>
988
989 Fix bug # 2169, also reported by other people on various systems.
990
991 * make.h: Some systems, such as Solaris and PTX, do not fully
992 implement POSIX-compliant SA_RESTART functionality; important
993 system calls like stat() and readdir() can still fail with EINTR
994 even if SA_RESTART has been set on the signal handler. So,
995 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
996 EINTR for system calls which return -1 or 0 (NULL), respectively,
997 on error.
998 Also, remove the old atomic_stat()/atomic_readdir() and
999 HAVE_BROKEN_RESTART handling.
1000
1001 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
1002
1003 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
1004 * remake.c (touch_file): Ditto.
1005
1006 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
1007 * read.c (construct_include_path): Ditto.
1008 * remake.c (name_mtime): Ditto.
1009 * vpath.c (selective_vpath_search): Ditto.
1010 * dir.c (find_directory): Ditto.
1011 (local_stat): Ditto.
1012 (find_directory): Use ENULLLOOP() to wrap opendir().
1013 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
1014
1015 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
1016 atomic_readdir() handling.
1017
10182003-01-22 Paul D. Smith <psmith@gnu.org>
1019
1020 * function.c (func_call): Fix Bug #1744. If we're inside a
1021 recursive invocation of $(call ...), mask any of the outer
1022 invocation's arguments that aren't used by this one, so that this
1023 invocation doesn't "inherit" them accidentally.
1024
10252002-12-05 Paul D. Smith <psmith@gnu.org>
1026
1027 * function.c (subst_expand): Valery Khamenia reported a
1028 pathological performance hit when doing substitutions on very
1029 large values with lots of words: turns out we were invoking
1030 strlen() a ridiculous number of times. Instead of having each
1031 call to sindex() call strlen() again, keep track of how much of
1032 the text we've seen and pass the length to sindex().
1033
10342002-11-19 Paul D. Smith <psmith@gnu.org>
1035
1036 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
1037
1038
10392002-11-16 Paul D. Smith <psmith@gnu.org>
1040
1041 * NMakefile.template (OBJS): Add hash.c object file.
1042 * SMakefile.template (srcs): Ditto.
1043 * Makefile.ami (objs): Ditto.
1044 * build_w32.bat: Ditto.
1045
1046 * Makefile.DOS.template: Remove extra dependencies.
1047
10482002-10-25 Paul D. Smith <psmith@gnu.org>
1049
1050 * expand.c (install_variable_buffer): New function. Install a new
1051 variable_buffer context and return the previous one.
1052 (restore_variable_buffer): New function. Free the current
1053 variable_buffer context and put a previously saved one back.
1054 * variable.h: Prototypes for {install,restore}_variable_buffer.
1055 * function.c (func_eval): Push a new variable_buffer context
1056 before we eval, then restore the old one when we're done.
1057 Fixes Bug #1517.
1058
1059 * read.c (install_conditionals): New function. Install a new
1060 conditional context and return the previous one.
1061 (restore_conditionals): New function. Free the current
1062 conditional context and put a previously saved one back.
1063 (eval): Use the {install,restore}_conditionals for "include"
1064 handling.
1065 (eval_buffer): Use {install,restore}_conditionals to preserve the
1066 present conditional state before we evaluate the buffer.
1067 Fixes Bug #1516.
1068
1069 * doc/make.texi (Quick Reference): Add references to $(eval ...)
1070 and $(value ...).
1071 (Recursion): Add a variable index entry for CURDIR.
1072
1073 * README.cvs: Update to appropriate versions.
1074 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
1075 don't need to copy loadavg.c: automake is smart enough to create
1076 it for me. Still have a bug in automake related to ansi2knr tho.
1077
10782002-10-14 Paul D. Smith <psmith@gnu.org>
1079
1080 * remake.c (notice_finished_file): Only touch targets if they have
1081 at least one command (as per POSIX). Resolve Bug #1418.
1082
1083 * *.c: Convert to using ANSI C-style function definitions.
1084 * Makefile.am: Enable the ansi2knr feature of automake.
1085 * configure.in: ditto.
1086
10872002-10-13 Paul D. Smith <psmith@gnu.org>
1088
1089 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
1090 for automatic variable values like $^, etc. In the case of very
1091 large lists of prerequisites this causes problems. Instead reuse
1092 a static buffer (resizeable) for each variable.
1093
1094 * read.c (eval): Fix Bug #1391: allow "export" keyword in
1095 target-specific variable definitions. Check for it and set an
1096 "exported" flag.
1097 (record_target_var): Set the export field to v_export if the
1098 "exported" flag is set.
1099 * doc/make.texi (Target-specific): Document the ability to use
1100 "export".
1101
1102 * doc/make.texi: Change the name of the section on automatic
1103 variables from "Automatic" to "Automatic Variables". Added text
1104 clarifying the scope of automatic variables.
1105
11062002-10-04 Paul D. Smith <psmith@gnu.org>
1107
1108 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
1109 as () braces.
1110 (record_files): Ditto.
1111
1112 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
1113 the search for the '=' to only within the enclosing parens.
1114
11152002-10-03 Paul D. Smith <psmith@gnu.org>
1116
1117 Version 3.80 released.
1118
1119 * dir.c: Change hash functions to use K&R function definition style.
1120 * function.c: Ditto.
1121 * read.c: Ditto.
1122 * variable.c: Ditto.
1123
1124 Update to automake 1.7.
1125
1126 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
1127 (pdf): Remove this target as automake now provides one.
1128
1129 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
1130
11312002-09-30 Martin P.J. Zinser <zinser@decus.de>
1132
1133 * makefile.com: Updates for GNU make 3.80.
1134 * makefile.vms: Ditto.
1135
11362002-09-23 Paul D. Smith <psmith@gnu.org>
1137
1138 * read.c (enum make_word_type): Remove w_comment.
1139 (get_next_mword): Don't treat comment characters as special; where
1140 this function is used we will never see a comment (it's stripped
1141 before we get here) and treating comments specially means that
1142 targets like "foo\#bar" aren't handled properly.
1143
11442002-09-18 Paul D. Smith <psmith@gnu.org>
1145
1146 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
1147
1148 * read.c (eval): Expansion of arguments to export/unexport was
1149 ignoring all arguments after the first one. Change the algorithm
1150 to expand the whole line once, then parse the results.
1151
11522002-09-17 Paul D. Smith <psmith@gnu.org>
1153
1154 Fix Bug #940 (plus another bug I found while looking at this):
1155
1156 * read.c (record_target_var): enter_file() will add a new entry if
1157 it's a double-colon target: we don't want to do that in this
1158 situation. Invoke lookup_file() and only enter_file() if it does
1159 not already exist. If the file we get back is a double-colon then
1160 add this variable to the "root" double-colon target.
1161
1162 * variable.c (initialize_file_variables): If this file is a
1163 double-colon target but is not the "root" target, then initialize
1164 the root and make the root's variable list the parent of our
1165 variable list.
1166
11672002-09-13 Paul D. Smith <psmith@gnu.org>
1168
1169 * doc/make.texi (MAKE Variable): Add some indexing for "+".
1170
1171 * hash.c (round_up_2): Get rid of a warning.
1172
11732002-09-12 Paul D. Smith <psmith@gnu.org>
1174
1175 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
1176 so it doesn't complain about getloadavg.c.
1177
1178 * commands.c (set_file_variables): Make sure we always alloca() at
1179 least 1 character for the value of $? (for '\0').
1180
11812002-09-11 Paul D. Smith <psmith@gnu.org>
1182
1183 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
1184 macro to use RESULT instead of the incorrect _RESULT_.
1185
1186 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
1187 and atomic_readdir(). We need to #include dirent.h to get this to
1188 work.
1189 * misc.c (atomic_readdir): Fix typos.
1190
11912002-09-10 Paul D. Smith <psmith@gnu.org>
1192
1193 * read.c (eval): Expand variable lists given to export and
1194 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
1195 (conditional_line): Ditto for "ifdef". Fixes bug #103.
1196
1197 * doc/make.texi (Variables/Recursion): Document this.
1198 (Conditional Syntax): And here.
1199
12002002-09-09 Paul D. Smith <psmith@gnu.org>
1201
1202 * configure.in: Check for memmove().
1203
12042002-09-07 Paul D. Smith <psmith@gnu.org>
1205
1206 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
1207 Michael Sterrett <msterret@coat.com> reports that while it has
1208 SA_RESTART, it does not work properly.
1209
1210 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
1211 that invokes stat() and loops to do it again if it returns EINTR.
1212 (atomic_readdir): Ditto, with readdir().
1213
1214 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
1215 and readdir() to atomic_stat() and atomic_readdir().
1216
12172002-09-04 Paul D. Smith <psmith@gnu.org>
1218
1219 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
1220 reports that GNU make sometimes doesn't recognize that targets can
1221 be made, when directories can be created as prerequisites. He
1222 reports that changing the order of predicates in the DEP->changed
1223 flag test so that lookup_file() is always performed, solves this
1224 problem.
1225
12262002-08-08 Paul D. Smith <psmith@gnu.org>
1227
1228 * configure.in: Require a newer version of gettext.
1229
1230 * misc.c (perror_with_name): Translate the format string (for
1231 right-to-left language support).
1232 (pfatal_with_name): Ditto.
1233
1234 * main.c: Create a static array of strings to store the usage
1235 text. This is done to facilitate translations.
1236 (struct command_switch): Remove argdesc and description fields.
1237 (switches): Remove values for obsolete fields.
1238 (print_usage): Print each element of the usage array.
1239
1240 * hash.c: Change function definitions to be K&R style.
1241
12422002-08-02 Paul D. Smith <psmith@gnu.org>
1243
1244 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
1245 this one because it's too hard to get right. We'll look at it for
1246 a future release.
1247 * main.c (main): Don't create the .TARGETS variable.
1248 * variable.c (handle_special_var): Don't handle .TARGETS.
1249
12502002-08-01 Paul D. Smith <psmith@gnu.org>
1251
1252 * main.c (switches): Add a new option, -B (--always-make). If
1253 specified, make will rebuild all targets that it encounters even
1254 if they don't appear to be out of date.
1255 (always_make_flag): New flag.
1256 * make.h: Extern always_make_flag.
1257 * remake.c (update_file_1): Check always_make_flag; if it's set we
1258 will always rebuild any target we can, even if none of its
1259 prerequisites are newer.
1260 * NEWS: Mention it.
1261
1262 * doc/make.texi (Shell Function): Make it clear that make
1263 variables marked as "export" are not passed to instances of the
1264 shell function.
1265
1266 Add new introspection variable .VARIABLES and .TARGETS.
1267
1268 * variable.c (handle_special_var): New function. If the variable
1269 reference passed in is "special" (.VARIABLES or .TARGETS),
1270 calculate the new value if necessary. .VARIABLES is handled here:
1271 walk through the hash of defined variables and construct a value
1272 which is a list of the names. .TARGETS is handled by
1273 build_target_list().
1274 (lookup_variable): Invoke handle_special_var().
1275 * file.c (build_target_list): Walk through the hask of known files
1276 and construct a list of the names of all the ones marked as
1277 targets.
1278 * main.c (main): Initialize them to empty (and as simple variables).
1279 * doc/make.texi (Special Variables): Document them.
1280 * NEWS: Mention them.
1281
1282 * variable.h (struct variable): Add a new flag "exportable" which
1283 is true if the variable name is valid for export.
1284 * variable.c (define_variable_in_set): Set "exportable" when a new
1285 variable is defined.
1286 (target_environment): Use the "exportable" flag instead of
1287 re-checking the name here... an efficiency improvement.
1288
12892002-07-31 Paul D. Smith <psmith@gnu.org>
1290
1291 * config.h-vms.template: Updates to build on VMS. Thanks to
1292 Brian_Benning@aksteel.com for helping verify the build.
1293 * makefile.com: Build the new hash.c file.
1294 * hash.h: Use strcpmi(), not stricmp(), in the
1295 HAVE_CASE_INSENSITIVE_FS case.
1296
12972002-07-30 Paul D. Smith <psmith@gnu.org>
1298
1299 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
1300 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
1301 Reported by <Brian_Benning@aksteel.com>.
1302
13032002-07-10 Paul D. Smith <psmith@gnu.org>
1304
1305 * variable.c (pop_variable_scope): Remove variable made unused by
1306 new hash infrastructure.
1307 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
1308 comparisons as well as name comparisons.
1309 * variable.h: Add a prototype for new hash_init_function_table().
1310 * file.c (lookup_file): Remove variables made unused by new hash
1311 infrastructure.
1312 * dir.c (directory_contents_hash_2): Missing return of hash value.
1313 (dir_contents_file_exists_p): Remove variables made unused by new
1314 hash infrastructure.
1315
1316

1321
1322 * scripts/functions/filter-out: Add literals to to the
1323 pattern space in order to add complexity, and trigger
1324 use of an internal hash table. Fix documentation strings.

1326 passed to expected `rm' command.
1327

1382 function_table_entry_hash_cmp): New functions.
1383 (lookup_function): Remove `table' argument.
1384 Use new hash table package.

1390 arglists are large enough to justify cost.
1391 (function_table_init): Renamed from function_table.
1392 (function_table): Declare as `struct hash_table'.
1393 (FUNCTION_TABLE_ENTRIES): New constant.

1402 Tighten inner search loops to test only for desired delimiters.
1403
1404 * variable.c (variable_hash_1, variable_hash_2,
1405 variable_hash_cmp): New functions.
1406 (variable_table): Declare as `struct hash_table'.
1407 (global_variable_set): Remove initialization.
1408 (init_hash_global_variable_set): New function.
1409 (define_variable_in_set): Use new hash table package.
1410 (lookup_variable): Likewise.
1411 (lookup_variable_in_set): Likewise.
1412 (initialize_file_variables): Likewise.
1413 (pop_variable_scope): Likewise.
1414 (create_new_variable_set): Likewise.
1415 (merge_variable_sets): Likewise.
1416 (define_automatic_variables): Likewise.
1417 (target_environment): Likewise.
1418 (print_variable_set): Likewise.

1421
1422 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
1423 prerequisite list. A real SysV make will expand the entire
1424 prerequisites list _twice_: we don't do that as it's a big
1425 backward-compatibility problem. We only replace those specific
1426 variables.
1427
1428 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
1429 references left in the list of prerequisites. Check for .POSIX as
1430 we record targets, so we can disable non-POSIX behavior while
1431 reading makefiles as well as running them.
1432 (eval): Check the prerequisite list to see if we have anything
1433 that looks like a SysV prerequisite variable reference.
1434
14352002-07-09 Paul D. Smith <psmith@gnu.org>
1436
1437 * doc/make.texi (Prerequisite Types): Add a new section describing
1438 order-only prerequisites.
1439
1440 * read.c (uniquize_deps): If we have the same file as both a
1441 normal and order-only prereq, get rid of the order-only prereq,
1442 since the normal one supersedes it.
1443
14442002-07-08 Paul D. Smith <psmith@gnu.org>
1445
1446 * AUTHORS: Added Greg McGary to the AUTHORS file.
1447 * NEWS: Blurbed order-only prerequisites.
1448 * file.c (print_file): Show order-only deps properly when printing
1449 the database.
1450
1451 * maintMakefile: Add "update" targets for wget'ing the latest
1452 versions of various external files. Taken from Makefile.maint in
1453 autoconf, etc.
1454
1455 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
1456 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
1457
14582002-07-07 Paul D. Smith <psmith@gnu.org>
1459
1460 * po/*.po: Remove. We'll use wget to retrieve them at release
1461 time.
1462
1463 * variable.c (do_variable_definition) [W32]: On W32 using cmd
1464 rather than a shell you get an exception. Make sure we look up
1465 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
1466
1467 * remake.c (notice_finished_file): Fix handling of -t flag.
1468 Patch provided by Henning Makholm <henning@makholm.net>.
1469
1470 * implicit.c (pattern_search): Some systems apparently run short
1471 of stack space, and using alloca() in this function caused an
1472 overrun. I modified it to use xmalloc() on the two variables
1473 which seemed like they might get large. Fixes Bug #476.
1474
1475 * main.c (print_version): Update copyright notice to conform with
1476 GNU standards.
1477 (print_usage): Update help output.
1478
1479 * function.c (func_eval): Create a new make function, $(eval
1480 ...). Expand the arguments, put them into a buffer, then invoke
1481 eval_buffer() on the resulting string.
1482 (func_quote): Create a new function, $(quote VARNAME). Inserts
1483 the value of the variable VARNAME without expanding it any
1484 further.
1485
1486 * read.c (struct ebuffer): Change the linebuffer structure to an
1487 "eval buffer", which can be either a file or a buffer.
1488 (eval_makefile): Move the code in the old read_makefile() which
1489 located a makefile into here: create a struct ebuffer with that
1490 information. Have it invoke the new function eval() with that
1491 ebuffer.
1492 (eval_buffer): Create a new function that creates a struct ebuffer
1493 that holds a string buffer instead of a file. Have it invoke
1494 eval() with that ebuffer.
1495 (eval): New function that contains the guts of the old
1496 read_makefile() function: this function parses makefiles. Obtains
1497 data to parse from the provided ebuffer. Some modifications to
1498 make the flow of the function cleaner and clearer. Still could
1499 use some work here...
1500 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
1501 contents of the define/endef variable from the ebuffer.
1502 (readstring): Read the next line from a string-style ebuffer.
1503 (readline): Read the next line from an ebuffer. If it's a string
1504 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
1505 from the file.
1506
1507 * dep.h (eval_buffer): Prototype eval_buffer();
1508
1509 * variable.c (do_variable_definition): Make sure that all
1510 non-target-specific variables are registered in the global set.
1511 If we're invoked from an $(eval ...) we might be inside a $(call
1512 ...) or other function which has pushed a variable scope; we still
1513 want to define our variables from evaluated makefile code in the
1514 global scope.
1515
15162002-07-03 Greg McGary <greg@mcgary.org>
1517
1518 * dep.h (struct dep) [ignore_mtime]: New member.
1519 [changed]: convert to a bitfield.
1520 * implicit.c (pattern_search): Zero ignore_mtime.
1521 * main.c (main, handle_non_switch_argument): Likewise.
1522 * rule.c (convert_suffix_rule): Likewise.
1523 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
1524 (read_makefile): Parse '|' in prerequisite list.
1525 (uniquize_deps): Consider ignore_mtime when comparing deps.
1526 * remake.c (update_file_1, check_dep): Don't force remake for
1527 dependencies that have d->ignore_mtime.
1528 * commands.c (FILE_LIST_SEPARATOR): New constant.
1529 (set_file_variables): Don't include a
1530 prerequisite in $+, $^ or $? if d->ignore_mtime.
1531 Define $|.
1532
15332002-06-18 Paul D. Smith <psmith@gnu.org>
1534
1535 * make.texinfo: Updates for next revision. New date/rev/etc.
1536 Recreate all Info menus. Change license on the manual to the GNU
1537 Free Documentation License. A number of typos.
1538 (Variables Simplify): Don't use "-" before it's defined.
1539 (Automatic Prerequisites): Rewrite the target example to work
1540 properly if the compile fails. Remove incorrect comments about
1541 how "set -e" behaves.
1542 (Text Functions): Move the "word", "wordlist", "words", and
1543 "firstword" functions here, from "File Name Functions".
1544 * make-stds.texi: Update from latest GNU version.
1545 * fdl.texi: (created) Import the latest GNU version.
1546
15472002-06-06 Paul D. Smith <psmith@gnu.org>
1548
1549 * variable.c (do_variable_definition): New function: extract the
1550 part of try_variable_definition() that actually sets the value
1551 into a separate function.
1552 (try_variable_definition): Call do_variable_definition() after
1553 parsing the variable definition string.
1554 (define_variable_in_set): Make the name argument const.
1555
1556 * variable.h (enum variable_flavor): Make public.
1557 (do_variable_definition): Create prototype.
1558
1559 * read.c (read_all_makefiles): Create a new built-in variable,
1560 MAKEFILE_LIST.
1561 (read_makefile): Add each makefile read in to this variable value.
1562
15632002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
1564
1565 * Makefile.DOS.template: Tweak according to changes in the
1566 distribution. Add back the dependencies of *.o files.
1567
1568 * configh.dos.template: Synchronize with config.h.in.
1569
15702002-05-09 Paul D. Smith <psmith@gnu.org>
1571
1572 * file.c (file_timestamp_now): Use K&R function declaration.
1573
1574 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
1575 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
1576 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
1577 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
1578 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
1579 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
1580 nlist.n_name is a pointer rather than an array.
1581
1582 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
1583 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
1584 * configure.in: Use it instead of the old version.
1585
1586 * main.c (main): Prefer setvbuf() to setlinebuf().
1587
15882002-05-08 Paul D. Smith <psmith@gnu.org>
1589
1590 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
1591 (loadavg_LDADD): Ditto.
1592
15932002-04-29 Paul D. Smith <psmith@gnu.org>
1594
1595 * expand.c (recursively_expand_for_file): Rename
1596 recursively_expand() to recursively_expand_for_file() and provide
1597 an extra argument, struct file. If the argument is provided, set
1598 the variable scope to that of the file before expanding.
1599 * variable.h (recursively_expand): Make this a macro that invokes
1600 recursively_expand_for_file() with a NULL file pointer.
1601 * variable.c (target_environment): Call the renamed function and
1602 provide the current file context.
1603 Fixes Debian bug #144306.
1604
16052002-04-28 Paul D. Smith <psmith@gnu.org>
1606
1607 Allow $(call ...) user-defined variables to be self-referencing
1608 without throwing an error. Allows implementation of transitive
1609 closures, among other possibly useful things.
1610 Requested by: Philip Guenther <guenther@sendmail.com>
1611
1612 * variable.h (struct variable): Add a new field: exp_count, and
1613 new macros to hold its size and maximum value.
1614 (warn_undefined): Make this a macro.
1615 * variable.c (define_variable_in_set): Initialize it.
1616 * expand.c (recursively_expand): If we detect recursive expansion
1617 of a variable, check the exp_count field. If it's greater than 0
1618 allow the recursion and decrement the count.
1619 (warn_undefined): Remove this (now a macro in variable.h).
1620 * function.c (func_call): Before we expand the user-defined
1621 function, modify its exp_count field to contain the maximum
1622 number of recursive calls we'll allow. After the call, reset it
1623 to 0.
1624
16252002-04-21 Paul D. Smith <psmith@gnu.org>
1626
1627 Modified to use latest autoconf (2.53), automake (1.6.1), and
1628 gettext (0.11.1). We're using gettext's new "external" support,
1629 to avoid including libintl source with GNU make.
1630
1631 * README.cvs: New file. Explain how to build GNU make from CVS.
1632
1633 * configure.in: Modify checking for the system glob library.
1634 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
1635 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
1636 etc. will manage it correctly). Set an automake conditional
1637 USE_LOCAL_GLOB to decide whether to compile the glob library.
1638
1639 * getloadavg.c (main): Include make.h in the "TEST" program to
1640 avoid warnings.
1641
1642 * Makefile.am: Remove special rules for loadavg. Replace them
1643 with Automake capabilities for building extra programs.
1644
1645 * signame.c: This file does nothing if the system provide
1646 strsignal(). If not, it implements strsignal(). If the system
1647 doesn't define sys_siglist, then we make our own; otherwise we use
1648 the system version.
1649 * signame.h: Removed.
1650
1651 * main.c (main): No need to invoke signame_init(). Update copyright.
1652
1653 * ABOUT-NLS: Removed.
1654 * gettext.c: Removed.
1655 * gettext.h: Get a simplified copy from the gettext package.
1656 * po/*: Created.
1657 * i18n/*.po: Moved to po/.
1658 * i18n/: Removed.
1659
1660 * config/*: Created. Contains package configuration helper files.
1661 * config.guess, config.sub: Moved to config directory.
1662
1663 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
1664 Rework to use new-style autoconf features. Use the "external"
1665 mode for gettext. Make the build.sh config file conditional on
1666 whether build.sh.in exists, to avoid autoconf errors.
1667 * acinclude.m4: Removed almost all macros as being obsolete.
1668 Rewrote remaining macros to use AC_DEFINE.
1669 * acconfig.h: Removed.
1670
1671 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
1672 conditional to handle customs support. Remove special handling
1673 for i18n features.
1674
16752002-04-20 Paul D. Smith <psmith@gnu.org>
1676
1677 * function.c (func_call): Don't mark the argument variables $1,
1678 etc. as recursive. They've already been fully expanded so
1679 there's no need to do it again, and doing so strips escaped $'s.
1680 Reported by Sebastian Glita <glseba@yahoo.com>.
1681
1682 * remake.c (notice_finished_file): Walk through double-colon
1683 entries via the prev field, not the next field!
1684 Reported by Greg McGary <greg@mcgary.org>.
1685
1686 * main.c (main): If the user specifies -q and asks for a specific
1687 target which is a makefile, we got an assert. In that case it
1688 turns out we should continue normally instead.
1689
1690 * i18n/de.po, i18n/fr.po: Installed an updated translation.
1691
1692 * i18n/he.po: Installed a new translation.
1693
16942002-01-07 Paul D. Smith <psmith@gnu.org>
1695
1696 * i18n/es.po, i18n/ru.po: Installed an updated translation.
1697
16982001-12-04 Paul D. Smith <psmith@gnu.org>
1699
1700 * i18n/ja.po: Installed an updated translation.
1701
17022001-09-06 Paul Eggert <eggert@twinsun.com>
1703
1704 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
1705 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
1706
1707 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
1708 are available.
1709 (main): Get rid of any avoidable limit on stack size.
1710
17112001-09-04 Paul D. Smith <psmith@gnu.org>
1712
1713 * i18n/da.po: Installed an updated translation.
1714
17152001-08-03 Paul D. Smith <psmith@gnu.org>
1716
1717 * i18n/fr.po: Installed an updated translation.
1718 Resolves Debian bug #106720.
1719
17202001-06-13 Paul D. Smith <psmith@gnu.org>
1721
1722 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
1723 translation.
1724
17252001-06-11 Paul D. Smith <psmith@gnu.org>
1726
1727 * i18n/ko.po: Installed a new translation.
1728
17292001-05-06 Paul D. Smith <psmith@gnu.org>
1730
1731 Modify the EINTR handling.
1732
1733 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
1734 the way in which we manage the file descriptor/signal handler race
1735 trap to be more efficient.
1736
17372001-05-06 Paul Eggert <eggert@twinsun.com>
1738
1739 Restart almost all system calls that are interrupted, instead
1740 of worrying about EINTR. The lone exception is the read() for
1741 job tokens.
1742
1743 * configure.in (HAVE_SA_RESTART): New macro.
1744 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
1745 * main.c (main): Use SA_RESTART instead of the old,
1746 nonstandard SA_INTERRUPT.
1747
1748 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
1749 * main.c (bsd_signal): New function or macro,
1750 if the implementation doesn't supply it.
1751 (The bsd_signal function will be in POSIX 1003.1-200x.)
1752 (HANDLESIG): Remove.
1753 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
1754
1755 * make.h (EINTR_SET): Remove.
1756 (SA_RESTART): New macro.
1757
1758 * arscan.c (ar_member_touch): Don't worry about EINTR.
1759 * function.c (func_shell): Likewise.
1760 * job.c (reap_children, free_child, new_job): Likewise.
1761 * main.c (main): Likewise.
1762 * remake.c (touch_file, name_mtime): Likewise.
1763
1764 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
1765 if fstat failed with errno!=EINTR, the error was ignored.
1766
1767 * job.c (set_child_handler_action_flags): New function.
1768 (new_job): Use it to temporarily clear the SIGCHLD action flags
1769 while reading the token.
1770
17712001-05-02 Paul D. Smith <psmith@gnu.org>
1772
1773 * job.c (start_job_command): Don't add define/endef per-line flags
1774 to the top-level flags setting.
1775
17762001-04-03 Paul D. Smith <psmith@gnu.org>
1777
1778 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
1779 bit on error, so check for odd return values, not non-0 return
1780 values.
1781 (VMS_get_member_info): Calculate the timezone differences correctly.
1782 Reported by John Fowler <jfowler@nyx.net>.
1783
1784
17852001-03-14 Paul D. Smith <psmith@gnu.org>
1786
1787 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
1788 value before invoking define_variable().
1789 Reported by John Fowler <jfowler@nyx.net>.
1790
17912001-02-07 Paul D. Smith <psmith@gnu.org>
1792
1793 * read.c (record_target_var): If we reset the variable due to a
1794 command-line variable setting overriding it, turn off the "append"
1795 flag.
1796
17972001-01-17 Paul D. Smith <psmith@gnu.org>
1798
1799 * variable.c (lookup_variable) [VMS]: When getting values from the
1800 environment, allocate enough space for the _value_ plus escapes,
1801 not enough space for the name plus escapes :-/.
1802 Reported by John Fowler <jfowler@nyx.net>.
1803
1804 * remake.c (f_mtime): Removed the "***" prefix from the mod time
1805 warnings that make generates, so it doesn't look like an error.
1806 Reported by Karl Berry <karl@gnu.org>.
1807
1808
1809 Fix for PR/2020: Rework appended target-specific variables. I'm
1810 fairly confident this algorithm is finally correct.
1811
1812 * expand.c (allocated_variable_append): Rewrite. Instead of
1813 expanding each appended variable then adding all the expanded
1814 strings together, we append all the unexpanded values going up
1815 through the variable set contexts, then expand the final result.
1816 This behaves just like non-target-specific appended variable
1817 values, while the old way didn't in various corner cases.
1818 (variable_append): New function: recursively append the unexpanded
1819 value of a variable, walking from the outermost variable scope to
1820 the innermost.
1821 * variable.c (lookup_variable): Remove the code that looked up the
1822 variable set list if the found variable was "append". We don't
1823 need this anymore.
1824 (lookup_variable_in_set): Make this non-static so we can use it
1825 elsewhere.
1826 (try_variable_definition): Use lookup_variable_in_set() rather
1827 than faking out current_variable_set_list by hand (cleanup).
1828 * variable.h: Add a prototype for the now non-static
1829 lookup_variable_in_set().
1830
18312000-11-17 Paul D. Smith <psmith@gnu.org>
1832
1833 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
1834 WINDOWS32 port to assume timestamps can be up to 3 seconds away
1835 before throwing a fit.
1836
18372000-11-17 Paul D. Smith <psmith@gnu.org>
1838
1839 * read.c (readline): CRLF calculations had a hole, if you hit the
1840 buffer grow scenario just right. Reworked the algorithm to avoid
1841 the need for len or lastlen at all. Problem description with
1842 sample code chages provided by Chris Faylor <cgf@redhat.com>.
1843
18442000-10-24 Paul D. Smith <psmith@gnu.org>
1845
1846 * gettext.c (SWAP): Declare this with the prototype, otherwise
1847 some systems don't work (non-32-bit? Reported for Cray T3E).
1848 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
1849
18502000-10-05 Paul D. Smith <psmith@gnu.org>
1851
1852 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
1853 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
1854
1855 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
1856
18572000-09-22 Paul D. Smith <psmith@gnu.org>
1858
1859 * gettext.c: Don't #define _GETTEXT_H here; we only include some
1860 parts of the real gettext.h here, and we expect to really include
1861 the real gettext.h later. If we keep this #define, it's ignored.
1862
18632000-09-21 Paul D. Smith <psmith@gnu.org>
1864
1865 * main.c (log_working_directory): Rework the text to use complete
1866 sentences, to make life simpler for the translators.
1867
18682000-08-29 Paul D. Smith <psmith@gnu.org>
1869
1870 * file.c (remove_intermediates): Print a debug message before we
1871 remove intermediate files, so the user (if she uses -d) knows
1872 what's going on.
1873
18742000-08-21 Paul D. Smith <psmith@gnu.org>
1875
1876 * variable.c (try_variable_definition): Change how we handle
1877 target-specific append variable defns: instead of just setting the
1878 value, expand it as an append _but_ only within the current
1879 target's context. Otherwise we lose all but the last value if the
1880 variable is appended more than once within the current target
1881 context. Fixes PR/1831.
1882
18832000-08-16 Paul D. Smith <psmith@gnu.org>
1884
1885 * function.c (func_shell): Nul-terminate the buffer before
1886 printing an exec error message (just in case it's not!).
1887 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
1888
18892000-07-25 Paul D. Smith <psmith@gnu.org>
1890
1891 * job.c (construct_command_argv_internal): Add "~" to the list of
1892 sh_chars[] which disallow optimizing out the shell call.
1893
18942000-07-23 Paul Eggert <eggert@twinsun.com>
1895
1896 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
1897 supersedes --disable-nsec-timestamps.
1898 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
1899 * README: Remove --disable-nsec-timestamps.
1900
1901 * filedef.h (struct file.low_resolution_time): New member.
1902 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
1903 * remake.c (update_file_1):
1904 Avoid spurious rebuilds due to low resolution time stamps,
1905 generalizing the earlier code that applied only to archive members.
1906 (f_mtime): Archive members always have low resolution time stamps.
1907
1908 * configure.in: Remove --disable-nsec-timestamps, as this has
1909 been superseded by .LOW_RESOLUTION_TIME.
1910
19112000-07-23 Paul Eggert <eggert@twinsun.com>
1912
1913 * configure.in (enable_nsec_timestamps): Renamed from
1914 make_cv_nsec_timestamps, since enable/disable options
1915 shouldn't be cached.
1916
19172000-07-23 Bruno Haible <haible@clisp.cons.org>
1918 and Paul Eggert <eggert@twinsun.com>
1919
1920 * file.c (file_timestamp_now):
1921 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
1922 so that clock_gettime is not linked unless needed.
1923
1924 * filedef.h (FILE_TIMESTAMP_HI_RES):
1925 Remove definition; "configure" now does this.
1926
1927 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
1928 to before high resolution file timestamp check,
1929 since that check now uses uintmax_t.
1930 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
1931 high resolution file timestamps.
1932 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
1933 so that we don't link in clock_gettime unnecessarily.
1934
19352000-07-17 Paul D. Smith <psmith@gnu.org>
1936
1937 * i18n/ja.po: New version of the translation file.
1938
19392000-07-07 Paul D. Smith <psmith@gnu.org>
1940
1941 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
1942 the offset calculation.
1943 (name_mtime): Replace EINTR test with EINTR_SET macro.
1944
19452000-07-07 Paul Eggert <eggert@twinsun.com>
1946
1947 Fix for PR/1811:
1948
1949 * remake.c (update_file_1):
1950 Avoid spurious rebuilds of archive members due to their
1951 timestamp resolution being only one second.
1952 (f_mtime): Avoid spurious warnings of timestamps in the future due to
1953 the clock's resolution being lower than file timestamps'.
1954 When warning about future timestamps, report only the discrepancy,
1955 not the absolute value of the timestamp and the current time.
1956
1957 * file.c (file_timestamp_now): New arg RESOLUTION.
1958 * filedef.h (file_timestamp_now): Likewise.
1959 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
1960
19612000-07-05 Paul D. Smith <psmith@gnu.org>
1962
1963 * variable.c (lookup_variable) [VMS]: Remove vestigial references
1964 to listp. Fixes PR/1793.
1965
19662000-06-26 Paul Eggert <eggert@twinsun.com>
1967
1968 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
1969
1970 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
1971
1972 * remake.c (f_mtime): Remove unused var memtime.
1973
19742000-06-25 Martin Buchholz <martin@xemacs.org>
1975
1976 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
1977 Ran spell-check on make.texinfo.
1978
19792000-06-23 Paul D. Smith <psmith@gnu.org>
1980
1981 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
1982 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
1983 * make.h: Define these macros.
1984
1985 * Version 3.79.1 released.
1986
1987 * configure.in: Add a new option, --disable-nsec-timestamps, to
1988 avoid using sub-second timestamps on systems that support it. It
1989 can lead to problems, e.g. if your makefile relies on "cp -p".
1990 * README.template: Document the issue with "cp -p".
1991
1992 * config.guess, config.sub: Updated.
