1 2004-11-28 Paul D. Smith <psmith@gnu.org>
3 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
4 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
5 Patch by Alessandro Vesely.
7 2004-11-12 Paul D. Smith <psmith@gnu.org>
9 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
10 the command line if it's inside a string.
11 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
13 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
15 * function.c (func_lastword): New function: return last word
16 from the list of words.
17 * doc/make.texi: Document $(lastword ). Fix broken links in
18 Quick Reference section.
20 2004-10-06 Paul D. Smith <psmith@gnu.org>
22 Apply patch from Alessandro Vesely, provided with bug # 9748.
23 Fix use of tmpnam() to work with Borland C.
25 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
26 construction of a temporary filename, and call new function
27 create_batch_filename().
28 (create_batch_filename) [WINDOWS32]: New function to create a
31 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
33 * read.c (record_target_var): Expand simple pattern-specific
35 * variable.c (initialize_file_variables): Do not expand simple
36 pattern-specific variable.
38 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
40 * remake.c (update_file_1): When rebuilding makefiles inherit
41 dontcare flag from a target that triggered update.
43 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
45 * variable.c (initialize_file_variables): Mark pattern-specific
46 variable as a per-target and copy export status.
48 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
50 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
52 * implicit.c (pattern_search): When considering an implicit rule's
53 prerequisite check that it is actually a target rather then
54 just an entry in the file hashtable.
56 2004-09-21 Paul D. Smith <psmith@gnu.org>
58 * read.c (readstring): Fix some logic errors in backslash handling.
59 (eval): Remove some unnecessary processing in buffer handling.
60 (record_target_var): Assert that parse_variable_definition() succeeded.
61 Reported by: Markus Mauhart <qwe123@chello.at>.
63 * misc.c: Removed the sindex() function. All instances of this
64 function were trivially replaceable by the standard strstr()
65 function, and that function will always have better (or certainly
66 no worse) performance than the very simple-minded algorithm
67 sindex() used. This can matter with complex makefiles.
68 * make.h: Remove the prototype for sindex().
69 * function.c (subst_expand): Convert sindex() call to strstr().
70 This means we no longer need to track the TLEN value so remove that.
71 (func_findstring): Convert sindex() to strstr().
72 * commands.c (chop_commands): Convert sindex() calls to strstr().
73 Suggested by: Markus Mauhart <qwe123@chello.at>.
75 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
76 idea behind Savannah Patch #3144 from david.baird@homemail.com.
77 If SHELL is set to CMD.EXE then assume it's batch-mode and
78 non-unixy. I wrote the code differently from the patch, though,
79 to make it safer. This also resolves bug #9174.
81 2004-09-20 Paul D. Smith <psmith@gnu.org>
83 * expand.c (variable_expand_string): Modify to invoke
84 patsubst_expand() instead of subst_expand(); the latter didn't
85 handle suffix patterns correctly.
86 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
87 was used only from variable_expand_string() and is no longer used
89 (func_subst): Ditto, on call to subst_expand().
90 (patsubst_expand): Require the percent pointers to point to the
91 character after the %, not to the % itself.
92 * read.c (record_files): New call criteria for patsubst_expand().
93 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
94 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
96 2004-09-19 Paul D. Smith <psmith@gnu.org>
98 * function.c (subst_expand): Fix a check in by_word: look for a
99 previous blank if we're beyond the beginning of the string, not
100 the beginning of the word.
101 Bugs reported by Markus Mauhart <qwe123@chello.at>.
103 2004-05-16 Paul D. Smith <psmith@gnu.org>
105 * remake.c (update_goal_chain): Change the argument specifying
106 whether we're rebuilding makefiles to be a global variable,
107 REBUILDING_MAKEFILES.
108 (complain): Extract the code that complains about no rules to make
109 a target into a separate function.
110 (update_file_1): If we tried to rebuild a file during the makefile
111 rebuild phase and it was dontcare, then no message was printed.
112 If we then try to build the same file during the normal build,
113 print a message this time.
114 (remake_file): Don't complain about un-remake-able files when
115 we're rebuilding makefiles.
117 2004-05-11 Paul D. Smith <psmith@gnu.org>
119 * job.c (construct_command_argv_internal): OS/2 patches from
120 Andreas Buening <andreas.buening@nexgo.de>.
122 2004-05-10 Paul D. Smith <psmith@gnu.org>
124 * remake.c (update_file): Don't walk the double-colon chain unless
125 this is a double-colon rule. Fix suggested by Boris Kolpackov
126 <boris@kolpackov.net>.
128 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
129 * readme.vms: New section describing OpenVMS support and issues.
130 * default.c (default_variables): Add support for IA64.
131 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
132 without some privilege aborts make with the error
133 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
134 pressing Ctrl+Y and the input device is no terminal. The change
135 catches this error and just continues.
137 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
139 2004-04-25 Paul D. Smith <psmith@gnu.org>
141 * commands.c (set_file_variables): Set $< properly in the face of
142 order-only prerequisites.
143 Patch from Boris Kolpackov <boris@kolpackov.net>
145 2004-04-21 Bob Byrnes <byrnes@curl.com>
147 * main.c (main): Notice failures to remake makefiles.
149 2004-03-28 Paul D. Smith <psmith@gnu.org>
151 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
153 * job.c: No default shell for RISC OS.
154 (load_too_high): Hard-code the return to 1.
155 (construct_command_argv_internal): No sh_chars or sh_cmds.
156 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
158 2004-03-20 Paul D. Smith <psmith@gnu.org>
160 * variable.c (do_variable_definition): Don't append from the
161 global set if a previous non-appending target-specific variable
162 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
165 * expand.c (reference_variable): Don't give up on variables with
166 no value that have the target-specific append flag set: they might
167 have a value after all. Reported by Oliver Schmidt
168 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
169 <nikulin@dx1cmd.inp.nsk.su>.
171 * rule.c (count_implicit_rule_limits): Don't delete patterns which
172 refer to absolute pathnames in directories that don't exist: some
173 portion of the makefile could create those directories before we
174 match the pattern. Fixes bugs #775 and #108.
176 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
178 * main.c (main): Free makefile_mtimes if we have any.
179 * README.W32.template: Update documentation for the current status
180 of the MS-Windows port.
181 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
182 environment variable is sometimes already defined which causes the
184 * main.c (debug_signal_handler): Only define this function if
185 SIGUSR1 is available.
187 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
189 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
190 * README.OS2.template: Documentation updates.
191 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
192 link line for safety.
193 * maintMakefile (build.sh.in): Remove an extraneous ")".
194 * job.c (child_execute_job): Close saved FDs.
195 * job.c (exec_command) [OS/2]: exec_command(): If the command
196 can't be exec'ed and if the shell is not Unix-sh, then try again
197 with argv = { "cmd", "/c", ... }. Normally, this code is never
198 reached for the cmd shell unless the command really doesn't exist.
199 (construct_command_argv_internal) [OS/2]: The code for cmd
200 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
201 The CMD builtin commands are case insensitive so use strcasecmp().
203 2004-03-19 Paul D. Smith <psmith@gnu.org>
205 * read.c (do_define): Re-order line counter increment so the count
206 is accurate (we were losing one line per define). Reported by
207 Dave Yost <Dave@Yost.com>.
209 2004-03-06 Paul D. Smith <psmith@gnu.org>
211 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
213 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
214 * misc.c (message,error,fatal): Ditto.
215 * configh.dos.template: Define HAVE_ANSI_COMPILER.
216 * config.h.W32.template: Ditto.
217 * config.h-vms.template: Ditto.
218 * config.ami.template: Ditto.
220 2004-03-04 Paul D. Smith <psmith@gnu.org>
222 * README.template: Add a note about broken /bin/sh on SunOS
223 4.1.3_U1 & 4.1.4. Fix up Savannah links.
225 * misc.c (message, error, fatal): Don't use "..." if we're using
226 varargs. ansi2knr should handle this but it doesn't work: it
227 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
228 done. On many systems (SunOS for example) va_dcl is a #define.
229 So, force the use of the non-"..." version on pre-ANSI compilers.
231 * maintMakefile (sign-dist): Create some rules to help automate
232 the new GNU ftp upload method.
234 2004-02-24 Paul D. Smith <psmith@gnu.org>
236 * config.h.W32.template: Add HAVE_STDARG_H
237 * config.h-vms.template: Ditto.
238 * config.ami.template: Ditto.
240 2004-02-23 Jonathan Grant <jg-make@jguk.org>
242 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
243 * build_w32.bat: Remove extra "+".
245 2004-02-23 Paul D. Smith <psmith@gnu.org>
247 * make.h: Create an UNUSED macro to mark unused parameters.
248 * (many): Clean up warnings by applying UNUSED, fixing
249 signed/unsigned incompatibilities, etc.
251 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
253 * filedef.h: Name the command_state enumeration.
254 * file.c (set_command_state): Use the enumeration in the function
257 * configure.in: Explicitly set SET_MAKE to empty, to disable
258 MAKE=make even when no make already exists. Fix bug #3823.
260 2004-02-22 Paul D. Smith <psmith@gnu.org>
262 * maintMakefile: Perl script to clean up all non-CVS files. Use
263 it on all the subdirectories for the cvs-clean target.
265 * main.c (decode_switches): Require non-empty strings for all our
266 string command-line options. Fixes Debian bug # 164165.
268 * configure.in: Check for stdarg.h and varargs.h.
269 * make.h (USE_VARIADIC): Set this if we can use variadic functions
270 for printing messages.
271 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
276 A number of patches for OS/2 support from Andreas Buening
277 <andreas.buening@nexgo.de>:
279 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
280 disable the SIGCHLD handler.
281 (reap_children) [OS/2]: Remove special handling of job_rfd.
282 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
283 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
284 * main.c (main) [OS/2]: Special handling for paths in OS/2.
285 * configure.in [OS/2]: Force SA_RESTART for OS/2.
286 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
289 2004-02-21 Paul D. Smith <psmith@gnu.org>
291 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
292 <mail@kristov.de> reports that if process_begin() fails we don't
293 handle the error condition correctly in all cases.
294 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
295 to have a newline on the message.
297 * job.c (construct_command_argv_internal): Add "test" to UNIX
298 sh_cmds[]. Fixes Savannah bug # 7606.
300 2004-02-04 Paul D. Smith <psmith@gnu.org>
302 * job.c (vms_handle_apos) [VMS]: Fix various string handling
303 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
304 Hartmut Becker <Hartmut.Becker@hp.com>.
306 2004-01-21 Paul D. Smith <psmith@gnu.org>
308 * job.c (load_too_high): Implement an algorithm to control the
309 "thundering herd" problem when using -l to control job creation
310 via the load average. The system only recomputes the load once a
311 second but we can start many jobs in a second. To solve this we
312 keep track of the number of jobs started in the last second and
313 apply a weight to try to guess what a correct load would be.
314 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
315 Also fixes bug #4693.
316 (reap_children): Decrease the job count for this second.
317 (start_job_command): Increase the job count for this second.
319 * read.c (conditional_line): Expand the text after ifn?def before
320 checking to see if it's a single word. Fixes bug #7257.
322 2004-01-09 Paul D. Smith <psmith@gnu.org>
324 * file.c (print_file): Recurse to print all targets in
325 double-colon rules. Fixes bug #4518, reported (with patch) by
326 Andrew Chatham <chatham@google.com>.
328 2004-01-07 Paul D. Smith <psmith@gnu.org>
330 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
331 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
332 AC_FUNC_SETVBUF_REVERSED.
334 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
335 (MAKE Variable): Fix Savannah bug #4898.
337 * job.c (construct_command_argv_internal): Add "!" to the list of
338 shell escape chars. POSIX sh allows it to appear before a
339 command, to negate the exit code. Fixes bug #6404.
341 * implicit.c (pattern_search): When matching an implicit rule,
342 remember which dependencies have the ignore_mtime flag set.
343 Original fix provided in Savannah patch #2349, by Benoit
344 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
346 2003-11-22 Paul D. Smith <psmith@gnu.org>
348 * README.W32.template (Outputs): Clarification on -j with
349 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
352 2003-11-02 Paul D. Smith <psmith@gnu.org>
354 * function.c (func_if): Strip all the trailing whitespace from the
355 condition, then don't expand it. Fixed bug # 5798.
357 * expand.c (recursively_expand_for_file): If we're expanding a
358 variable with no file context, then use the variable's context.
361 2003-10-21 Paul D. Smith <psmith@gnu.org>
363 * main.c (log_working_directory): Add newlines to printf()s.
365 * README.cvs: Add a note to ignore warnings during autoreconf.
367 * maintMakefile (po_repo): Set a new URL for PO file updates.
368 (get-config/config.guess get-config/config.sub): Get these files
369 from the Savannah config project instead of ftp.gnu.org.
371 2003-08-22 Paul D. Smith <psmith@gnu.org>
373 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
374 systems which don't yet implement the C89 standard :-/.
376 2003-07-18 Paul D. Smith <psmith@gnu.org>
378 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
379 [WINDOWS32]: Initialize hash.
381 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
383 * dir.c (read_dirstream): Provide a workaround for broken versions of
384 the MinGW dirent structure.
386 2003-05-30 Earnie Boyd <earnie@users.sf.net>
388 * w32/include/dirent.h: Add __MINGW32__ filter.
390 2003-05-30 Earnie Boyd <earnie@users.sf.net>
392 * make.h: Add global declaration of *make_host.
393 * main.c (print_usage): Remove local declaration of *make_host.
394 (print_version): Display "This program built for ..." after Copyright
397 2003-05-30 Earnie Boyd <earnie@users.sf.net>
399 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
400 execution of "makeinfo --html make.texi".
402 2003-04-30 Paul D. Smith <psmith@gnu.org>
404 * build.template: Make some changes to maybe allow this script to
405 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
407 * README.OS2.template: New file for OS/2 support. Original
408 contributed by Andreas Buening.
409 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
412 2003-04-19 Paul D. Smith <psmith@gnu.org>
414 Fix bug #1405: allow a target to match multiple pattern-specific
417 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
418 variable.c, where they've always belonged.
419 * rule.h: Move the prototypes and struct pattern_var as well.
420 * variable.c (initialize_file_variables): Invoke
421 lookup_pattern_var() in a loop, until no more matches are found.
422 If a match is found, create a new variable set for the target's
423 pattern variables. Then merge the contents of each matching
424 pattern variable set into the target's pattern variable set.
425 (lookup_pattern_var): Change this function to be usable
426 in a loop. It takes a starting position: if NULL, start at the
427 beginning; if non-NULL, start with the pattern variable after that
428 position, and return the next matching pattern.
429 (create_pattern_var): Create a unique instance of
430 pattern-specific variables for every definition in the makefile.
431 Don't combine the same pattern together. This allows us to
432 process the variable handling properly even when the same pattern
433 is used multiple times.
434 (parse_variable_definition): New function: break out the parsing
435 of a variable definition line from try_variable_definition.
436 (try_variable_definition): Call parse_variable_definition to
438 (print_variable_data_base): Print out pattern-specific variables.
439 * variable.h (struct variable): Remember when a variable is
440 conditional. Also remember its flavor.
441 (struct pattern_var): Instead of keeping a variable set, we just
442 keep a single variable for each pattern.
443 * read.c (record_target_var): Each pattern variable contains only a
444 single variable, not a set, so create it properly.
445 * doc/make.texi (Pattern-specific): Document the new behavior.
447 2003-04-17 Paul D. Smith <psmith@gnu.org>
449 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
450 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
451 file/directory naming rules for VMS so I can't tell whether this
454 2003-04-09 Paul D. Smith <psmith@gnu.org>
456 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
457 DOS-style pathnames: backslash separators and drive specifiers.
459 2003-03-28 Paul D. Smith <psmith@gnu.org>
461 * file.c (snap_deps): If .SECONDARY with no targets is given, set
462 the intermediate flag on all targets. Fixes bug #2515.
464 2003-03-24 Paul D. Smith <psmith@gnu.org>
466 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
467 Upgrade to autoconf 2.57 and automake 1.7.3.
469 * job.c: More OS/2 changes from Andreas Buening.
471 * file.c (print_file): Fix variable initialization.
474 * remake.c (notice_finished_file):
476 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
477 some calls (like readdir()) return NULL in valid situations
478 without resetting errno. Fixes bug #2846.
480 2003-02-25 Paul D. Smith <psmith@gnu.org>
482 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
484 * job.c (_is_unixy_shell) [OS/2]: New function.
485 Set default shell to /bin/sh.
486 (reap_children): Close the job_rfd pipe here since we don't use a
488 (set_child_handler_action_flags): define this to empty on OS/2.
489 (start_job_command): Close the jobserver pipe and use
490 child_execute_job() instead of fork/exec.
491 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
492 rather than exec'ing, then reconfigure stdin/stdout.
493 (exec_command): Rewrite to use spawn instead of exec. Return the
496 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
497 in DOS. Handle the TEMP environment variable as in DOS. Don't
498 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
499 use -j in DOS mode. Use child_execute_job() instead of
502 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
505 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
506 prototypes that return values.
508 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
510 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
511 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
513 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
516 2003-02-24 Paul D. Smith <psmith@gnu.org>
518 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
519 * job.c (child_execute_job) [VMS]: New code for handling spawn().
520 (child_execute_job) [VMS]: Handle error status properly.
521 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
523 * function.c (func_shell): Use EINTRLOOP() while reading from the
524 subshell pipe (Fixes bug #2502).
525 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
527 * main.c (main): Ditto.
529 2003-01-30 Paul D. Smith <psmith@gnu.org>
531 * read.c (eval): eval() was not fully reentrant, because the
532 collapsed buffer was static. Change it to be an automatic
533 variable so that eval() can be invoked recursively.
535 (eval): Apply patch # 1022: fix memory reference error on long
536 target-specific variable lines.
537 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
539 * function.c (check_numeric): Combine the is_numeric() function
540 into this function, since it's only called from one place.
541 Constify this function. Have it print the incorrect string in the
542 error message. Fixes bug #2407.
543 (strip_whitespace): Constify.
545 * expand.c (expand_argument): Constify.
547 2003-01-29 Paul D. Smith <psmith@gnu.org>
549 Fix bug # 2169, also reported by other people on various systems.
551 * make.h: Some systems, such as Solaris and PTX, do not fully
552 implement POSIX-compliant SA_RESTART functionality; important
553 system calls like stat() and readdir() can still fail with EINTR
554 even if SA_RESTART has been set on the signal handler. So,
555 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
556 EINTR for system calls which return -1 or 0 (NULL), respectively,
558 Also, remove the old atomic_stat()/atomic_readdir() and
559 HAVE_BROKEN_RESTART handling.
561 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
563 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
564 * remake.c (touch_file): Ditto.
566 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
567 * read.c (construct_include_path): Ditto.
568 * remake.c (name_mtime): Ditto.
569 * vpath.c (selective_vpath_search): Ditto.
570 * dir.c (find_directory): Ditto.
572 (find_directory): Use ENULLLOOP() to wrap opendir().
573 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
575 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
576 atomic_readdir() handling.
578 2003-01-22 Paul D. Smith <psmith@gnu.org>
580 * function.c (func_call): Fix Bug #1744. If we're inside a
581 recursive invocation of $(call ...), mask any of the outer
582 invocation's arguments that aren't used by this one, so that this
583 invocation doesn't "inherit" them accidentally.
585 2002-12-05 Paul D. Smith <psmith@gnu.org>
587 * function.c (subst_expand): Valery Khamenia reported a
588 pathological performance hit when doing substitutions on very
589 large values with lots of words: turns out we were invoking
590 strlen() a ridiculous number of times. Instead of having each
591 call to sindex() call strlen() again, keep track of how much of
592 the text we've seen and pass the length to sindex().
594 2002-11-19 Paul D. Smith <psmith@gnu.org>
596 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
599 2002-11-16 Paul D. Smith <psmith@gnu.org>
601 * NMakefile.template (OBJS): Add hash.c object file.
602 * SMakefile.template (srcs): Ditto.
603 * Makefile.ami (objs): Ditto.
604 * build_w32.bat: Ditto.
606 * Makefile.DOS.template: Remove extra dependencies.
608 2002-10-25 Paul D. Smith <psmith@gnu.org>
610 * expand.c (install_variable_buffer): New function. Install a new
611 variable_buffer context and return the previous one.
612 (restore_variable_buffer): New function. Free the current
613 variable_buffer context and put a previously saved one back.
614 * variable.h: Prototypes for {install,restore}_variable_buffer.
615 * function.c (func_eval): Push a new variable_buffer context
616 before we eval, then restore the old one when we're done.
619 * read.c (install_conditionals): New function. Install a new
620 conditional context and return the previous one.
621 (restore_conditionals): New function. Free the current
622 conditional context and put a previously saved one back.
623 (eval): Use the {install,restore}_conditionals for "include"
625 (eval_buffer): Use {install,restore}_conditionals to preserve the
626 present conditional state before we evaluate the buffer.
629 * doc/make.texi (Quick Reference): Add references to $(eval ...)
631 (Recursion): Add a variable index entry for CURDIR.
633 * README.cvs: Update to appropriate versions.
634 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
635 don't need to copy loadavg.c: automake is smart enough to create
636 it for me. Still have a bug in automake related to ansi2knr tho.
638 2002-10-14 Paul D. Smith <psmith@gnu.org>
640 * remake.c (notice_finished_file): Only touch targets if they have
641 at least one command (as per POSIX). Resolve Bug #1418.
643 * *.c: Convert to using ANSI C-style function definitions.
644 * Makefile.am: Enable the ansi2knr feature of automake.
645 * configure.in: ditto.
647 2002-10-13 Paul D. Smith <psmith@gnu.org>
649 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
650 for automatic variable values like $^, etc. In the case of very
651 large lists of prerequisites this causes problems. Instead reuse
652 a static buffer (resizeable) for each variable.
654 * read.c (eval): Fix Bug #1391: allow "export" keyword in
655 target-specific variable definitions. Check for it and set an
657 (record_target_var): Set the export field to v_export if the
658 "exported" flag is set.
659 * doc/make.texi (Target-specific): Document the ability to use
662 * doc/make.texi: Change the name of the section on automatic
663 variables from "Automatic" to "Automatic Variables". Added text
664 clarifying the scope of automatic variables.
666 2002-10-04 Paul D. Smith <psmith@gnu.org>
668 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
670 (record_files): Ditto.
672 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
673 the search for the '=' to only within the enclosing parens.
675 2002-10-03 Paul D. Smith <psmith@gnu.org>
677 Version 3.80 released.
679 * dir.c: Change hash functions to use K&R function definition style.
684 Update to automake 1.7.
686 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
687 (pdf): Remove this target as automake now provides one.
689 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
691 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
693 * makefile.com: Updates for GNU make 3.80.
694 * makefile.vms: Ditto.
696 2002-09-23 Paul D. Smith <psmith@gnu.org>
698 * read.c (enum make_word_type): Remove w_comment.
699 (get_next_mword): Don't treat comment characters as special; where
700 this function is used we will never see a comment (it's stripped
701 before we get here) and treating comments specially means that
702 targets like "foo\#bar" aren't handled properly.
704 2002-09-18 Paul D. Smith <psmith@gnu.org>
706 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
708 * read.c (eval): Expansion of arguments to export/unexport was
709 ignoring all arguments after the first one. Change the algorithm
710 to expand the whole line once, then parse the results.
712 2002-09-17 Paul D. Smith <psmith@gnu.org>
714 Fix Bug #940 (plus another bug I found while looking at this):
716 * read.c (record_target_var): enter_file() will add a new entry if
717 it's a double-colon target: we don't want to do that in this
718 situation. Invoke lookup_file() and only enter_file() if it does
719 not already exist. If the file we get back is a double-colon then
720 add this variable to the "root" double-colon target.
722 * variable.c (initialize_file_variables): If this file is a
723 double-colon target but is not the "root" target, then initialize
724 the root and make the root's variable list the parent of our
727 2002-09-13 Paul D. Smith <psmith@gnu.org>
729 * doc/make.texi (MAKE Variable): Add some indexing for "+".
731 * hash.c (round_up_2): Get rid of a warning.
733 2002-09-12 Paul D. Smith <psmith@gnu.org>
735 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
736 so it doesn't complain about getloadavg.c.
738 * commands.c (set_file_variables): Make sure we always alloca() at
739 least 1 character for the value of $? (for '\0').
741 2002-09-11 Paul D. Smith <psmith@gnu.org>
743 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
744 macro to use RESULT instead of the incorrect _RESULT_.
746 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
747 and atomic_readdir(). We need to #include dirent.h to get this to
749 * misc.c (atomic_readdir): Fix typos.
751 2002-09-10 Paul D. Smith <psmith@gnu.org>
753 * read.c (eval): Expand variable lists given to export and
754 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
755 (conditional_line): Ditto for "ifdef". Fixes bug #103.
757 * doc/make.texi (Variables/Recursion): Document this.
758 (Conditional Syntax): And here.
760 2002-09-09 Paul D. Smith <psmith@gnu.org>
762 * configure.in: Check for memmove().
764 2002-09-07 Paul D. Smith <psmith@gnu.org>
766 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
767 Michael Sterrett <msterret@coat.com> reports that while it has
768 SA_RESTART, it does not work properly.
770 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
771 that invokes stat() and loops to do it again if it returns EINTR.
772 (atomic_readdir): Ditto, with readdir().
774 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
775 and readdir() to atomic_stat() and atomic_readdir().
777 2002-09-04 Paul D. Smith <psmith@gnu.org>
779 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
780 reports that GNU make sometimes doesn't recognize that targets can
781 be made, when directories can be created as prerequisites. He
782 reports that changing the order of predicates in the DEP->changed
783 flag test so that lookup_file() is always performed, solves this
786 2002-08-08 Paul D. Smith <psmith@gnu.org>
788 * configure.in: Require a newer version of gettext.
790 * misc.c (perror_with_name): Translate the format string (for
791 right-to-left language support).
792 (pfatal_with_name): Ditto.
794 * main.c: Create a static array of strings to store the usage
795 text. This is done to facilitate translations.
796 (struct command_switch): Remove argdesc and description fields.
797 (switches): Remove values for obsolete fields.
798 (print_usage): Print each element of the usage array.
800 * hash.c: Change function definitions to be K&R style.
802 2002-08-02 Paul D. Smith <psmith@gnu.org>
804 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
805 this one because it's too hard to get right. We'll look at it for
807 * main.c (main): Don't create the .TARGETS variable.
808 * variable.c (handle_special_var): Don't handle .TARGETS.
810 2002-08-01 Paul D. Smith <psmith@gnu.org>
812 * main.c (switches): Add a new option, -B (--always-make). If
813 specified, make will rebuild all targets that it encounters even
814 if they don't appear to be out of date.
815 (always_make_flag): New flag.
816 * make.h: Extern always_make_flag.
817 * remake.c (update_file_1): Check always_make_flag; if it's set we
818 will always rebuild any target we can, even if none of its
819 prerequisites are newer.
822 * doc/make.texi (Shell Function): Make it clear that make
823 variables marked as "export" are not passed to instances of the
826 Add new introspection variable .VARIABLES and .TARGETS.
828 * variable.c (handle_special_var): New function. If the variable
829 reference passed in is "special" (.VARIABLES or .TARGETS),
830 calculate the new value if necessary. .VARIABLES is handled here:
831 walk through the hash of defined variables and construct a value
832 which is a list of the names. .TARGETS is handled by
834 (lookup_variable): Invoke handle_special_var().
835 * file.c (build_target_list): Walk through the hask of known files
836 and construct a list of the names of all the ones marked as
838 * main.c (main): Initialize them to empty (and as simple variables).
839 * doc/make.texi (Special Variables): Document them.
840 * NEWS: Mention them.
842 * variable.h (struct variable): Add a new flag "exportable" which
843 is true if the variable name is valid for export.
844 * variable.c (define_variable_in_set): Set "exportable" when a new
846 (target_environment): Use the "exportable" flag instead of
847 re-checking the name here... an efficiency improvement.
849 2002-07-31 Paul D. Smith <psmith@gnu.org>
851 * config.h-vms.template: Updates to build on VMS. Thanks to
852 Brian_Benning@aksteel.com for helping verify the build.
853 * makefile.com: Build the new hash.c file.
854 * hash.h: Use strcpmi(), not stricmp(), in the
855 HAVE_CASE_INSENSITIVE_FS case.
857 2002-07-30 Paul D. Smith <psmith@gnu.org>
859 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
860 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
861 Reported by <Brian_Benning@aksteel.com>.
863 2002-07-10 Paul D. Smith <psmith@gnu.org>
865 * variable.c (pop_variable_scope): Remove variable made unused by
866 new hash infrastructure.
867 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
868 comparisons as well as name comparisons.
869 * variable.h: Add a prototype for new hash_init_function_table().
870 * file.c (lookup_file): Remove variables made unused by new hash
872 * dir.c (directory_contents_hash_2): Missing return of hash value.
873 (dir_contents_file_exists_p): Remove variables made unused by new
877 Installed Greg McGary's integration of the hash functions from the
878 GNU id-utils package:
880 2002-07-10 Greg McGary <greg@mcgary.org>
882 * scripts/functions/filter-out: Add literals to to the
883 pattern space in order to add complexity, and trigger
884 use of an internal hash table. Fix documentation strings.
885 * scripts/targets/INTERMEDIATE: Reverse order of files
886 passed to expected `rm' command.
888 2002-07-10 Greg McGary <greg@mcgary.org>

948 (func_filter_filterout): Pass through patterns noting boundaries
949 and '%', if present. Note a_word length. Use a hash table if

960 (find_char_unquote): Accept two char-constant stop chars, rather
961 than a string constant, avoiding zillions of calls to strchr.
962 Tighten inner search loops to test only for desired delimiters.

980 2002-07-10 Paul D. Smith <psmith@gnu.org>
982 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
983 prerequisite list. A real SysV make will expand the entire
984 prerequisites list _twice_: we don't do that as it's a big
985 backward-compatibility problem. We only replace those specific
988 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
989 references left in the list of prerequisites. Check for .POSIX as
990 we record targets, so we can disable non-POSIX behavior while
991 reading makefiles as well as running them.
992 (eval): Check the prerequisite list to see if we have anything
993 that looks like a SysV prerequisite variable reference.
995 2002-07-09 Paul D. Smith <psmith@gnu.org>
997 * doc/make.texi (Prerequisite Types): Add a new section describing
998 order-only prerequisites.
1000 * read.c (uniquize_deps): If we have the same file as both a
1001 normal and order-only prereq, get rid of the order-only prereq,
1002 since the normal one supersedes it.
1004 2002-07-08 Paul D. Smith <psmith@gnu.org>
1006 * AUTHORS: Added Greg McGary to the AUTHORS file.
1007 * NEWS: Blurbed order-only prerequisites.
1008 * file.c (print_file): Show order-only deps properly when printing
1011 * maintMakefile: Add "update" targets for wget'ing the latest
1012 versions of various external files. Taken from Makefile.maint in
1015 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
1016 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
1018 2002-07-07 Paul D. Smith <psmith@gnu.org>
1020 * po/*.po: Remove. We'll use wget to retrieve them at release
1023 * variable.c (do_variable_definition) [W32]: On W32 using cmd
1024 rather than a shell you get an exception. Make sure we look up
1025 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
1027 * remake.c (notice_finished_file): Fix handling of -t flag.
1028 Patch provided by Henning Makholm <henning@makholm.net>.
1030 * implicit.c (pattern_search): Some systems apparently run short
1031 of stack space, and using alloca() in this function caused an
1032 overrun. I modified it to use xmalloc() on the two variables
1033 which seemed like they might get large. Fixes Bug #476.
1035 * main.c (print_version): Update copyright notice to conform with
1037 (print_usage): Update help output.
1039 * function.c (func_eval): Create a new make function, $(eval
1040 ...). Expand the arguments, put them into a buffer, then invoke
1041 eval_buffer() on the resulting string.
1042 (func_quote): Create a new function, $(quote VARNAME). Inserts
1043 the value of the variable VARNAME without expanding it any
1046 * read.c (struct ebuffer): Change the linebuffer structure to an
1047 "eval buffer", which can be either a file or a buffer.
1048 (eval_makefile): Move the code in the old read_makefile() which
1049 located a makefile into here: create a struct ebuffer with that
1050 information. Have it invoke the new function eval() with that
1052 (eval_buffer): Create a new function that creates a struct ebuffer
1053 that holds a string buffer instead of a file. Have it invoke
1054 eval() with that ebuffer.
1055 (eval): New function that contains the guts of the old
1056 read_makefile() function: this function parses makefiles. Obtains
1057 data to parse from the provided ebuffer. Some modifications to
1058 make the flow of the function cleaner and clearer. Still could
1059 use some work here...
1060 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
1061 contents of the define/endef variable from the ebuffer.
1062 (readstring): Read the next line from a string-style ebuffer.
1063 (readline): Read the next line from an ebuffer. If it's a string
1064 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
1067 * dep.h (eval_buffer): Prototype eval_buffer();
1069 * variable.c (do_variable_definition): Make sure that all
1070 non-target-specific variables are registered in the global set.
1071 If we're invoked from an $(eval ...) we might be inside a $(call
1072 ...) or other function which has pushed a variable scope; we still
1073 want to define our variables from evaluated makefile code in the
1076 2002-07-03 Greg McGary <greg@mcgary.org>
1078 * dep.h (struct dep) [ignore_mtime]: New member.
1079 [changed]: convert to a bitfield.
1080 * implicit.c (pattern_search): Zero ignore_mtime.
1081 * main.c (main, handle_non_switch_argument): Likewise.
1082 * rule.c (convert_suffix_rule): Likewise.
1083 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
1084 (read_makefile): Parse '|' in prerequisite list.
1085 (uniquize_deps): Consider ignore_mtime when comparing deps.
1086 * remake.c (update_file_1, check_dep): Don't force remake for
1087 dependencies that have d->ignore_mtime.
1088 * commands.c (FILE_LIST_SEPARATOR): New constant.
1089 (set_file_variables): Don't include a
1090 prerequisite in $+, $^ or $? if d->ignore_mtime.
1093 2002-06-18 Paul D. Smith <psmith@gnu.org>
1095 * make.texinfo: Updates for next revision. New date/rev/etc.
1096 Recreate all Info menus. Change license on the manual to the GNU
1097 Free Documentation License. A number of typos.
1098 (Variables Simplify): Don't use "-" before it's defined.
1099 (Automatic Prerequisites): Rewrite the target example to work
1100 properly if the compile fails. Remove incorrect comments about
1101 how "set -e" behaves.
1102 (Text Functions): Move the "word", "wordlist", "words", and
1103 "firstword" functions here, from "File Name Functions".
1104 * make-stds.texi: Update from latest GNU version.
1105 * fdl.texi: (created) Import the latest GNU version.
1107 2002-06-06 Paul D. Smith <psmith@gnu.org>
1109 * variable.c (do_variable_definition): New function: extract the
1110 part of try_variable_definition() that actually sets the value
1111 into a separate function.
1112 (try_variable_definition): Call do_variable_definition() after
1113 parsing the variable definition string.
1114 (define_variable_in_set): Make the name argument const.
1116 * variable.h (enum variable_flavor): Make public.
1117 (do_variable_definition): Create prototype.
1119 * read.c (read_all_makefiles): Create a new built-in variable,
1121 (read_makefile): Add each makefile read in to this variable value.
1123 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
1125 * Makefile.DOS.template: Tweak according to changes in the
1126 distribution. Add back the dependencies of *.o files.
1128 * configh.dos.template: Synchronize with config.h.in.
1130 2002-05-09 Paul D. Smith <psmith@gnu.org>
1132 * file.c (file_timestamp_now): Use K&R function declaration.
1134 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
1135 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
1136 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
1137 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
1138 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
1139 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
1140 nlist.n_name is a pointer rather than an array.
1142 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
1143 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
1144 * configure.in: Use it instead of the old version.
1146 * main.c (main): Prefer setvbuf() to setlinebuf().
1148 2002-05-08 Paul D. Smith <psmith@gnu.org>
1150 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
1151 (loadavg_LDADD): Ditto.
1153 2002-04-29 Paul D. Smith <psmith@gnu.org>
1155 * expand.c (recursively_expand_for_file): Rename
1156 recursively_expand() to recursively_expand_for_file() and provide
1157 an extra argument, struct file. If the argument is provided, set
1158 the variable scope to that of the file before expanding.
1159 * variable.h (recursively_expand): Make this a macro that invokes
1160 recursively_expand_for_file() with a NULL file pointer.
1161 * variable.c (target_environment): Call the renamed function and
1162 provide the current file context.
1163 Fixes Debian bug #144306.
1165 2002-04-28 Paul D. Smith <psmith@gnu.org>
1167 Allow $(call ...) user-defined variables to be self-referencing
1168 without throwing an error. Allows implementation of transitive
1169 closures, among other possibly useful things.
1170 Requested by: Philip Guenther <guenther@sendmail.com>
1172 * variable.h (struct variable): Add a new field: exp_count, and
1173 new macros to hold its size and maximum value.
1174 (warn_undefined): Make this a macro.
1175 * variable.c (define_variable_in_set): Initialize it.
1176 * expand.c (recursively_expand): If we detect recursive expansion
1177 of a variable, check the exp_count field. If it's greater than 0
1178 allow the recursion and decrement the count.
1179 (warn_undefined): Remove this (now a macro in variable.h).
1180 * function.c (func_call): Before we expand the user-defined
1181 function, modify its exp_count field to contain the maximum
1182 number of recursive calls we'll allow. After the call, reset it
1185 2002-04-21 Paul D. Smith <psmith@gnu.org>
1187 Modified to use latest autoconf (2.53), automake (1.6.1), and
1188 gettext (0.11.1). We're using gettext's new "external" support,
1189 to avoid including libintl source with GNU make.
1191 * README.cvs: New file. Explain how to build GNU make from CVS.
1193 * configure.in: Modify checking for the system glob library.
1194 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
1195 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
1196 etc. will manage it correctly). Set an automake conditional
1197 USE_LOCAL_GLOB to decide whether to compile the glob library.
1199 * getloadavg.c (main): Include make.h in the "TEST" program to
1202 * Makefile.am: Remove special rules for loadavg. Replace them
1203 with Automake capabilities for building extra programs.
1205 * signame.c: This file does nothing if the system provide
1206 strsignal(). If not, it implements strsignal(). If the system
1207 doesn't define sys_siglist, then we make our own; otherwise we use
1209 * signame.h: Removed.
1211 * main.c (main): No need to invoke signame_init(). Update copyright.
1213 * ABOUT-NLS: Removed.
1214 * gettext.c: Removed.
1215 * gettext.h: Get a simplified copy from the gettext package.
1217 * i18n/*.po: Moved to po/.
1220 * config/*: Created. Contains package configuration helper files.
1221 * config.guess, config.sub: Moved to config directory.
1223 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
1224 Rework to use new-style autoconf features. Use the "external"
1225 mode for gettext. Make the build.sh config file conditional on
1226 whether build.sh.in exists, to avoid autoconf errors.
1227 * acinclude.m4: Removed almost all macros as being obsolete.
1228 Rewrote remaining macros to use AC_DEFINE.
1229 * acconfig.h: Removed.
1231 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
1232 conditional to handle customs support. Remove special handling
1235 2002-04-20 Paul D. Smith <psmith@gnu.org>
1237 * function.c (func_call): Don't mark the argument variables $1,
1238 etc. as recursive. They've already been fully expanded so
1239 there's no need to do it again, and doing so strips escaped $'s.
1240 Reported by Sebastian Glita <glseba@yahoo.com>.
1242 * remake.c (notice_finished_file): Walk through double-colon
1243 entries via the prev field, not the next field!
1244 Reported by Greg McGary <greg@mcgary.org>.
1246 * main.c (main): If the user specifies -q and asks for a specific
1247 target which is a makefile, we got an assert. In that case it
1248 turns out we should continue normally instead.
1250 * i18n/de.po, i18n/fr.po: Installed an updated translation.
1252 * i18n/he.po: Installed a new translation.
1254 2002-01-07 Paul D. Smith <psmith@gnu.org>
1256 * i18n/es.po, i18n/ru.po: Installed an updated translation.
1258 2001-12-04 Paul D. Smith <psmith@gnu.org>
1260 * i18n/ja.po: Installed an updated translation.
1262 2001-09-04 Paul D. Smith <psmith@gnu.org>
1264 * i18n/da.po: Installed an updated translation.
1266 2001-08-03 Paul D. Smith <psmith@gnu.org>
1268 * i18n/fr.po: Installed an updated translation.
1269 Resolves Debian bug #106720.
1271 2001-06-13 Paul D. Smith <psmith@gnu.org>
1273 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
1276 2001-06-11 Paul D. Smith <psmith@gnu.org>
1278 * i18n/ko.po: Installed a new translation.
1280 2001-05-06 Paul D. Smith <psmith@gnu.org>
1282 Modify the EINTR handling.
1284 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
1285 the way in which we manage the file descriptor/signal handler race
1286 trap to be more efficient.
1288 2001-05-06 Paul Eggert <eggert@twinsun.com>
1290 Restart almost all system calls that are interrupted, instead
1291 of worrying about EINTR. The lone exception is the read() for
1294 * configure.in (HAVE_SA_RESTART): New macro.
1295 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
1296 * main.c (main): Use SA_RESTART instead of the old,
1297 nonstandard SA_INTERRUPT.
1299 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
1300 * main.c (bsd_signal): New function or macro,
1301 if the implementation doesn't supply it.
1302 (The bsd_signal function will be in POSIX 1003.1-200x.)
1303 (HANDLESIG): Remove.
1304 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
1306 * make.h (EINTR_SET): Remove.
1307 (SA_RESTART): New macro.
1309 * arscan.c (ar_member_touch): Don't worry about EINTR.
1310 * function.c (func_shell): Likewise.
1311 * job.c (reap_children, free_child, new_job): Likewise.
1312 * main.c (main): Likewise.
1313 * remake.c (touch_file, name_mtime): Likewise.
1315 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
1316 if fstat failed with errno!=EINTR, the error was ignored.
1318 * job.c (set_child_handler_action_flags): New function.
1319 (new_job): Use it to temporarily clear the SIGCHLD action flags
1320 while reading the token.
1322 2001-05-02 Paul D. Smith <psmith@gnu.org>
1324 * job.c (start_job_command): Don't add define/endef per-line flags
1325 to the top-level flags setting.
1327 2001-04-03 Paul D. Smith <psmith@gnu.org>
1329 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
1330 bit on error, so check for odd return values, not non-0 return
1332 (VMS_get_member_info): Calculate the timezone differences correctly.
1333 Reported by John Fowler <jfowler@nyx.net>.
1336 2001-03-14 Paul D. Smith <psmith@gnu.org>
1338 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
1339 value before invoking define_variable().
1340 Reported by John Fowler <jfowler@nyx.net>.
1342 2001-02-07 Paul D. Smith <psmith@gnu.org>
1344 * read.c (record_target_var): If we reset the variable due to a
1345 command-line variable setting overriding it, turn off the "append"
1348 2001-01-17 Paul D. Smith <psmith@gnu.org>
1350 * variable.c (lookup_variable) [VMS]: When getting values from the
1351 environment, allocate enough space for the _value_ plus escapes,
1352 not enough space for the name plus escapes :-/.
1353 Reported by John Fowler <jfowler@nyx.net>.
1355 * remake.c (f_mtime): Removed the "***" prefix from the mod time
1356 warnings that make generates, so it doesn't look like an error.
1357 Reported by Karl Berry <karl@gnu.org>.
1360 Fix for PR/2020: Rework appended target-specific variables. I'm
1361 fairly confident this algorithm is finally correct.
1363 * expand.c (allocated_variable_append): Rewrite. Instead of
1364 expanding each appended variable then adding all the expanded
1365 strings together, we append all the unexpanded values going up
1366 through the variable set contexts, then expand the final result.
1367 This behaves just like non-target-specific appended variable
1368 values, while the old way didn't in various corner cases.
1369 (variable_append): New function: recursively append the unexpanded
1370 value of a variable, walking from the outermost variable scope to
1372 * variable.c (lookup_variable): Remove the code that looked up the
1373 variable set list if the found variable was "append". We don't
1375 (lookup_variable_in_set): Make this non-static so we can use it
1377 (try_variable_definition): Use lookup_variable_in_set() rather
1378 than faking out current_variable_set_list by hand (cleanup).
1379 * variable.h: Add a prototype for the now non-static
1380 lookup_variable_in_set().
1382 2000-11-17 Paul D. Smith <psmith@gnu.org>
1384 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
1385 WINDOWS32 port to assume timestamps can be up to 3 seconds away
1386 before throwing a fit.
1388 2000-11-17 Paul D. Smith <psmith@gnu.org>
1390 * read.c (readline): CRLF calculations had a hole, if you hit the
1391 buffer grow scenario just right. Reworked the algorithm to avoid
1392 the need for len or lastlen at all. Problem description with
1393 sample code chages provided by Chris Faylor <cgf@redhat.com>.
1395 2000-10-24 Paul D. Smith <psmith@gnu.org>
1397 * gettext.c (SWAP): Declare this with the prototype, otherwise
1398 some systems don't work (non-32-bit? Reported for Cray T3E).
1399 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
1401 2000-10-05 Paul D. Smith <psmith@gnu.org>
1403 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
1404 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
1406 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
1408 2000-09-22 Paul D. Smith <psmith@gnu.org>
1410 * gettext.c: Don't #define _GETTEXT_H here; we only include some
1411 parts of the real gettext.h here, and we expect to really include
1412 the real gettext.h later. If we keep this #define, it's ignored.
1414 2000-09-21 Paul D. Smith <psmith@gnu.org>
1416 * main.c (log_working_directory): Rework the text to use complete
1417 sentences, to make life simpler for the translators.
1419 2000-08-29 Paul D. Smith <psmith@gnu.org>
1421 * file.c (remove_intermediates): Print a debug message before we
1422 remove intermediate files, so the user (if she uses -d) knows
1425 2000-08-21 Paul D. Smith <psmith@gnu.org>
1427 * variable.c (try_variable_definition): Change how we handle
1428 target-specific append variable defns: instead of just setting the
1429 value, expand it as an append _but_ only within the current
1430 target's context. Otherwise we lose all but the last value if the
1431 variable is appended more than once within the current target
1432 context. Fixes PR/1831.
1434 2000-08-16 Paul D. Smith <psmith@gnu.org>
1436 * function.c (func_shell): Nul-terminate the buffer before
1437 printing an exec error message (just in case it's not!).
1438 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
1440 2000-07-25 Paul D. Smith <psmith@gnu.org>
1442 * job.c (construct_command_argv_internal): Add "~" to the list of
1443 sh_chars[] which disallow optimizing out the shell call.
1445 2000-07-23 Paul Eggert <eggert@twinsun.com>
1447 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
1448 supersedes --disable-nsec-timestamps.
1449 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
1450 * README: Remove --disable-nsec-timestamps.
1452 * filedef.h (struct file.low_resolution_time): New member.
1453 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
1454 * remake.c (update_file_1):
1455 Avoid spurious rebuilds due to low resolution time stamps,
1456 generalizing the earlier code that applied only to archive members.
1457 (f_mtime): Archive members always have low resolution time stamps.
1459 * configure.in: Remove --disable-nsec-timestamps, as this has
1460 been superseded by .LOW_RESOLUTION_TIME.
1462 2000-07-23 Paul Eggert <eggert@twinsun.com>
1464 * configure.in (enable_nsec_timestamps): Renamed from
1465 make_cv_nsec_timestamps, since enable/disable options
1466 shouldn't be cached.
1468 2000-07-23 Bruno Haible <haible@clisp.cons.org>
1469 and Paul Eggert <eggert@twinsun.com>
1471 * file.c (file_timestamp_now):
1472 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
1473 so that clock_gettime is not linked unless needed.
1475 * filedef.h (FILE_TIMESTAMP_HI_RES):
1476 Remove definition; "configure" now does this.
1478 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
1479 to before high resolution file timestamp check,
1480 since that check now uses uintmax_t.
1481 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
1482 high resolution file timestamps.
1483 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
1484 so that we don't link in clock_gettime unnecessarily.
1486 2000-07-17 Paul D. Smith <psmith@gnu.org>
1488 * i18n/ja.po: New version of the translation file.
1490 2000-07-07 Paul D. Smith <psmith@gnu.org>
1492 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
1493 the offset calculation.
1494 (name_mtime): Replace EINTR test with EINTR_SET macro.
1496 2000-07-07 Paul Eggert <eggert@twinsun.com>
1500 * remake.c (update_file_1):
1501 Avoid spurious rebuilds of archive members due to their
1502 timestamp resolution being only one second.
1503 (f_mtime): Avoid spurious warnings of timestamps in the future due to
1504 the clock's resolution being lower than file timestamps'.
1505 When warning about future timestamps, report only the discrepancy,
1506 not the absolute value of the timestamp and the current time.
1508 * file.c (file_timestamp_now): New arg RESOLUTION.
1509 * filedef.h (file_timestamp_now): Likewise.
1510 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
1512 2000-07-05 Paul D. Smith <psmith@gnu.org>
1514 * variable.c (lookup_variable) [VMS]: Remove vestigial references
1515 to listp. Fixes PR/1793.
1517 2000-06-26 Paul Eggert <eggert@twinsun.com>
1519 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
1521 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
1523 * remake.c (f_mtime): Remove unused var memtime.
1525 2000-06-25 Martin Buchholz <martin@xemacs.org>
1527 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
1528 Ran spell-check on make.texinfo.
1530 2000-06-23 Paul D. Smith <psmith@gnu.org>
1532 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
1533 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
1534 * make.h: Define these macros.
1536 * Version 3.79.1 released.
1538 * configure.in: Add a new option, --disable-nsec-timestamps, to
1539 avoid using sub-second timestamps on systems that support it. It
1540 can lead to problems, e.g. if your makefile relies on "cp -p".
1541 * README.template: Document the issue with "cp -p".
1543 * config.guess, config.sub: Updated.
1547 See ChangeLog.2, available in the CVS repository at:
