733 which allows the caller to get the index of the matching directory.
735 * make.h (vpath_search): Update prototype.
737 * remake.c (library_search): Implement linker-compatible library
738 search. Use the new VPATH_SEARCH index functionality to keep track

742 * implicit.c (pattern_search): Pass NULL for the index arguments in
743 the VPATH_SEARCH call.
745 * doc/make.texi (Directory Search for Link Libraries): Describe the

804 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
806 * commands.c (set_file_variables): Avoid modifying the dep
807 chain to achieve uniqueness. Fixes savannah bug 25780.

835 2009-10-03 Paul Smith <psmith@gnu.org>
837 * make.h: Include <alloca.h> even on systems where __GNUC__ is

897 double-colons have a different meaning. Savannah bug #27497.
899 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
901 * configh.dos.template: Remove unconditional definition of
902 SYS_SIGLIST_DECLARED.
903 Include <sys/version.h> because ports of GCC 4.3.0 and later no
904 longer include it, so macros like __DJGPP_MINOR__ are no longer
905 defined automatically.
907 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
908 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
909 instead of using the hardcoded ones.
910 (SUBDIRS): doc subdir added.
911 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
912 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
913 create html formated docs. texi2html may not be ported to DOS.
914 (make.info, make.dvi, make.ps, make.html): Make targets depend on
916 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
917 -I switch to look in ./ instead of ./doc.
918 (html): Target depend on html-recursive instead of make_1.html.
919 (make_1.html): Removed.
920 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
921 (all-recursive): Allow for more than one subdir in the build
923 (mostlyclean-recursive, clean-recursive, distclean-recursive)
924 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
925 (tags-recursive): Allow for more than one subdir in the build
927 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
928 targets. Enter into doc/ to produce the targets.
929 (all-am): $(INFO_DEPS) replaced by info.
931 2009-09-26 Paul Smith <psmith@gnu.org>
933 * read.c (record_files): Use free_ns() to free struct nameseq.
936 * rule.c (freerule): Use free_dep_chain().
938 * read.c (record_files): Free FILENAMES chain for implicit rules.
939 (eval): Static pattern targets go into the string cache.
941 * function.c (string_glob): Free NAME in the nameseq chain.
943 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
945 * implicit.c (pattern_search): Terminate early if we haven't
946 found any rules to try (performance improvement).
948 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
950 * implicit.c (pattern_search): Merge three parallel arrays,
951 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
952 of struct TRYRULE. In the old version the latter two arrays
953 had insufficient length.
955 2009-09-24 Paul Smith <psmith@gnu.org>
957 * implicit.c (pattern_search): Add back support for order-only
958 prerequisites for secondary expansion implicit rules, that were
959 accidentally dropped. If we find a "|", enable order-only mode
960 and set IGNORE_MTIME on all deps that are seen afterward.
961 (pattern_search): Fix memory leaks: for intermediate files where
962 we've already set the file variable and pattern variable sets, be
963 sure to either save or free them as appropriate.
965 2009-09-23 Paul Smith <psmith@gnu.org>
967 Rework the way secondary expansion is stored, for efficiency.
968 This changes secondary expansion so that ONLY WHEN we know we have
969 a possibility of needing secondary expansion, do we defer the
970 secondary expansion. This means more parsing the deps but we use
971 a lot less memory (due to the strcache). Also, this fixes
974 * read.c (eval): Don't parse the dep string here anymore.
975 (record_files): Take the dep argument as an unparsed string. If
976 secondary expansion is enabled AND the prereq string has a '$' in
977 it, then set NEED_2ND_EXPANSION and keep the entire string.
978 Otherwise, parse the dep string here to construct the dep list
979 with the names in the strcache.
981 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
982 duplicate the name string (others are in the strcache).
984 * implicit.c: Remove struct idep and free_idep_chain(): unused.
985 (struct patdeps): New structure to store prereq information.
986 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
987 which prerequisites need expansion, and expand only those.
989 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
990 and enter_prereqs(). split_prereqs() takes a fully-expanded string
991 and splits it into a DEP list, handling order-only prereqs.
992 (enter_prereqs): This function enters a list of DEPs into the file
993 database. If there's a stem defined, expand any pattern chars.
994 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
995 set. Use the above functions.
996 (snap_deps): Only perform second expansion on prereqs that need it,
997 as defined by the NEED_2ND_EXPANSION flag.
998 (print_prereqs): New function to print the prereqs
999 (print_file): Call print_prereqs() rather than print inline.
1001 * hash.h (STRING_COMPARE): Take advantage of strcache() by
1003 (STRING_N_COMPARE): Ditto.
1004 (ISTRING_COMPARE): Ditto.
1006 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
1007 (parse_file_seq): Return void*
1008 * read.c (parse_file_seq): Return void*.
1009 (eval): Invoke macroized version of parse_file_seq()
1010 * default.c (set_default_suffixes): Ditto.
1011 * file.c (split_prereqs): Ditto.
1012 * function.c (string_glob): Ditto.
1013 * main.c (main): Ditto.
1014 * rule.c (install_pattern_rule): Ditto.
1016 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
1018 2009-09-16 Paul Smith <psmith@gnu.org>
1020 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
1022 * dep.h: Create alloc_dep() / free_dep() macros.
1024 * implicit.c (pattern_search): Take advantage of the new
1025 parse_file_seq() to add the directory prefix to each prereq.
1027 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
1028 all. Avoid reversing chains. Support adding prefixes.
1029 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
1030 cached/non-cached results.
1031 (eval): Remove multi_glob() & invoke new parse_file_seq().
1032 * rule.c (install_pattern_rule): Ditto.
1033 * main.c (main): Ditto.
1034 * implicit.c (pattern_search): Ditto.
1035 * function.c (string_glob): Ditto.
1036 * file.c (parse_prereqs): Ditto.
1037 * default.c (set_default_suffixes): Ditto.
1039 * variable.c (parse_variable_definition): Don't run off the end of
1040 the string if it ends in whitespace (found with valgrind).
1042 * commands.c (set_file_variables): Keep space for all targets in
1043 $? if -B is given (found with valgrind).
1045 2009-09-15 Paul Smith <psmith@gnu.org>
1047 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
1048 (xcalloc): Add new function.
1049 * make.h: New declarations.
1051 * ar.c (ar_glob_match): New calling method for concat().
1052 * main.c (main): Ditto.
1053 (decode_env_switches): Ditto.
1054 * read.c (eval_makefile): Ditto.
1055 (tilde_expand): Ditto.
1056 (parse_file_seq): Ditto.
1057 * variable.c (target_environment): Ditto.
1058 (sync_Path_environment): Ditto.
1060 * ar.c (ar_glob_match): Use xcalloc().
1061 * dir.c (file_impossible): Ditto.
1062 * file.c (enter_file): Ditto.
1063 * job.c (new_job): Ditto.
1064 * read.c (parse_file_seq): Ditto.
1065 * vmsfunctions.c (opendir): Ditto.

1069 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
1070 inside the loop that looks up environment for PATH.
1072 2009-08-31 Eli Zaretskii <eliz@gnu.org>
1074 * function.c (windows32_openpipe): Update envp after calling
1075 sync_Path_environment.
1077 2009-08-02 Paul Smith <psmith@gnu.org>
1079 * remake.c (notice_finished_file): Ensure file->cmds is not null
1080 before looping through them. Fixes Savannah bug #21824.
1082 * doc/make.texi (Wildcard Examples): Clarify when objects is
1083 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1084 (Include): Clarify the behavior of -include.
1085 Fixes Savannah bug #18963.
1087 2009-08-01 Paul Smith <psmith@gnu.org>
1089 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1090 etc. come on the command line. Fixes Savannah bug #27093.
1092 * expand.c (expand_argument): If the argument is large enough use
1093 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1095 * variable.c (do_variable_definition): Avoid using alloca() to
1096 hold values, which can be large. Fixes Savannah bug #23960.
1098 * job.c (new_job): Use memmove() instead of strcpy() since both
1099 pointers are in the same memory block. Fixes Savannah bug #27148.
1100 Patch by Petr Machata.
1102 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1104 * job.c (construct_command_argv_internal): Add "ulimit" and
1105 "unset" to the sh_cmds for Unixy shells.
1107 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1109 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1110 that set make_cv_sys_gnu_glob, so they are also correctly set
1111 when the cache has been populated before.
1113 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1115 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1116 exist, as realpath(3) does where it's supported.
1118 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1120 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1121 (abspath): Support systems that define HAVE_DOS_PATHS (have
1122 drive letters in their file names). Use IS_PATHSEP instead of a
1123 literal '/' comparison. Fixes Savannah bug #26886.
1125 2009-06-14 Paul Smith <psmith@gnu.org>
1127 * remake.c (update_file_1): Remember the original file we marked
1128 as updating, so we can clear that flag again. If we find a target
1129 via vpath, FILE might change.
1130 (check_dep): Ditto. Fixes Savannah bug #13529.
1131 Patch by Reid Madsen <reid.madsen@tek.com>.
1133 2009-06-13 Paul Smith <psmith@gnu.org>
1135 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1136 included by MAKEFILES cannot give default goals.
1137 * read.c (eval): If set_default is not set, pass the no-default-goal
1138 value when we read included makefiles. Fixes Savannah bug #13401.
1140 * ar.c (ar_name): Ensure that targets with empty parens aren't
1141 considered archive member references: archive members must have a
1142 non-empty "member" string. Fixes Savannah bug #18435.
1144 * function.c (string_glob): Rely on multi_glob() to determine
1145 whether files exist or not. Remove call to file_exists_p() which
1146 is not always correct. Fixes Savannah bug #21231.
1147 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1148 then only files that really exist will be returned.
1149 * dep.h: Add new argument to multi_glob().
1150 * rule.c (install_pattern_rule): Ditto.
1151 * read.c (eval): Ditto.
1152 * main.c (main): Ditto.
1153 * implicit.c (pattern_search): Ditto.
1154 * file.c (parse_prereqs): Ditto.
1155 * default.c (set_default_suffixes): Ditto.
1157 2009-06-09 Paul Smith <psmith@gnu.org>
1159 * commands.c (set_file_variables): If always_make_flag is set,
1160 always add the prereq to $?. Fixes Savannah bug #17825.
1162 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1163 to rebuild the deps of all the also_make targets for that file.
1164 Fixes Savannah bug #19108.
1166 * implicit.c (pattern_search): Undo test for is_target, added by
1167 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1168 Rule Search Algorithm". Fixes Savannah bug #17752.
1170 * main.c (clean_jobserver): Clear the jobserver_fds options and
1171 set job_slots to the default when we clean up.
1172 (define_makeflags): Return the new MAKEFLAGS value.
1173 (main): Reset MAKEFLAGS in the environment when we re-exec.
1174 Fixes Savannah bug #18124.
1176 2009-06-08 Paul Smith <psmith@gnu.org>
1178 * read.c (eval): Collapse continuations post-semicolon on target-
1179 specific variables. Fixes Savannah bug #17521.
1181 2009-06-07 Paul Smith <psmith@gnu.org>
1183 * job.c (reap_children): For older systems without waitpid() (are
1184 there any of these left?) run wait(2) inside EINTRLOOP to handle
1185 EINTR errors. Fixes Savannah bug #16401.
1187 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1189 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1191 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1192 not the end, to catch second expansion $(eval ...) defining new
1193 target/prereq relationships during snap_deps.
1194 Fixes Savannah bug #24622.
1196 * read.c (record_files): The second-expansion "f->updating" hack
1197 was not completely correct: if assumed that the target with
1198 commands always had prerequisites; if one didn't then the ordering
1199 was messed up. Fixed for now to use f->updating to decide whether
1200 to preserve the last element in the deps list... but this whole
1201 area of constructing and reversing the deps list is too confusing
1202 and needs to be reworked. Fixes Savannah bug #21198.
1204 2009-06-06 Paul Smith <psmith@gnu.org>
1206 * hash.c (hash_insert): Remove useless test for NULL.
1207 Fixes Savannah bug #21823.
1209 * make.h: Move SET_STACK_SIZE determination to make.h.
1210 * main.c (main): New global variable, STACK_LIMIT, holds the
1211 original stack limit when make was started.
1212 * job.c (start_job_command): Reset the stack limit, if we changed it.
1213 Fixes Savannah bug #22010.
1215 * remake.c (check_dep): Only set the target's state to not-started
1216 if it's not already running. Found this while testing -j10 builds
1217 of glibc: various targets were being rebuilt multiple times.
1218 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1221 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1222 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1225 2009-06-04 Paul Smith <psmith@gnu.org>
1227 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1229 * maintMakefile: Modify access of config and gnulib Savannah
1230 modules to use GIT instead of CVS.
1232 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1233 Fixes Savannah bug #24655.
1235 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1236 this can happen during some invocations of $(eval ...) for example.
1237 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1239 2009-06-02 Paul Smith <psmith@gnu.org>
1241 * configure.in: Check for fileno()
1242 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1243 for the makefile file so invocations of $(shell ...) don't inherit it.
1244 Fixes Savannah bug #24277.
1246 2009-06-01 Paul Smith <psmith@gnu.org>
1248 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1249 expansion was handled incorrectly. Rework the default goal
1250 handling to save the variable only. Remove default_goal_file and
1252 * read.c (eval): Check default_goal_var, not default_goal_name.
1253 * read.c (record_target_var): Don't check default_goal_file here.
1255 2009-05-31 Paul Smith <psmith@gnu.org>
1257 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1258 it, and if the multi_glob() returns nothing (say it expanded to
1259 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1261 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1262 $(and ..) to the reference. Fixes Savannah bug #25694.
1264 * make.1: Be clear that some recipes will be executed even with -n.
1265 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1267 * doc/make.texi (Override Directive): Make more clear how
1268 overrides and appends interact.
1269 Elucidates part of Savannah bug #26207.
1271 * read.c (record_target_var): Don't reset the origin on
1272 target-specific variables; try_variable_definition() will handle
1273 this correctly. Fixes Savannah bug #26207.
1275 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1276 Fixes Savannah bug #25712.
1278 * implicit.c (pattern_search): Keep a pointer to the beginning of
1279 the filename and save that instead of the constructed pointer.
1280 Fixes Savannah bug #26593.
1281 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1283 2009-05-30 Paul Smith <psmith@gnu.org>
1285 * doc/make.texi (Multi-Line): Add a description of the new abilities
1286 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1287 "command sequence" vs. "recipe" syntax.
1288 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1289 after a define, to create variables with those flavors.
1291 2009-05-25 Paul Smith <psmith@gnu.org>
1293 Reworked the parser for variable assignments to allow multiple
1294 modifiers, and in any order. Also allows variable and
1295 prerequisites to be modifier names ('export', 'private', etc.)
1297 * NEWS: Add notes about user-visible changes.
1299 * read.c (struct vmodifiers): Remember what modifiers were seen.
1300 (parse_var_assignment): New function to parse variable assignments.
1301 (eval): Call the new function. Handle variable assignments earlier.
1303 * variable.c (parse_variable_definition): Only parse; don't create var.
1304 (assign_variable_definition): Call parse, then create the var.
1306 2009-05-24 Paul Smith <psmith@gnu.org>
1308 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1309 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1311 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1313 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1314 Fixes Savannah bug #25412.
1316 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1317 prototype for xmalloc.
1318 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1319 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1320 Loop over an array of extensions, instead of duplicating the same
1321 code inline. Use SearchPath followed by CreateFile, instead of
1322 the obsolete OpenFile. Fixes Savannah bug #17277.
1323 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1324 to `find_file'. Fixes Savannah bug #25662.
1326 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1328 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1329 Fixes Savannah bug #20495.
1331 2009-02-28 Ralf Wildenhues <address@hidden>
1333 * doc/make.texi (Instead of Execution): Document interaction of
1334 -t with phony targets.
1336 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1338 Introduce a new keyword "private" which applies to target-specific
1339 variables and prevents their values from being inherited.
1341 * variable.h (struct variable): Add private_var flag to each variable.
1342 Add a flag to specify which list entry switches to the parent target.
1343 * variable.c (define_variable_in_set): Initialize private_var flag.

1356 * make.h: Rename savestring to xstrndup.
1357 * commands.c (chop_commands): Ditto.
1358 * function.c (func_foreach): Ditto.
1359 * read.c (eval, record_files): Ditto.
1360 * variable.c (define_variable_in_set): Ditto.
1362 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1364 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1367 * w32/subproc/build.bat (GCCBuild): Likewise.
1369 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1371 * job.c (construct_command_argv_internal): Avoid extra backslash
1372 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1375 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1377 * README.W32.template: Remove obsolete text about non-support for
1378 -jN without Unixy shell. Remove obsolete text about not supplying
1379 Visual Studio project files (we do supply them). Modify text to
1380 prefer GCC builds to MSC builds.
1382 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1384 * doc/make.texi (Empty Targets): Fix typo.
1386 2008-03-27 Paul Smith <psmith@gnu.org>

1399 `value' field is NULL.
1401 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1403 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1405 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1406 (TEXINFOS): Value changed to `doc/make.texi'.
1407 (.SUFFIXES): Use .texi instead of .texinfo.
1408 (make.info, make.dvi): Depend on doc/make.texi.
1409 (.texi.info): New target, instead of ".texinfo.info". Change -I
1410 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1411 (.texi): New target, instead of ".texinfo". Change -I switch to
1412 $(MAKEINFO) to look in doc/. Use --no-split.
1413 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1414 switch to $(MAKEINFO) to look in doc/.
1415 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1416 "*.i[0-9][0-9]" (due to --no-split above).

1418 (html, make_1.html): New targets.
1419 (.PHONY): Add "html".

1425 HAVE_DECL_SYS_SIGLIST.
1427 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1428 build does not use child_execute_job.
1430 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1431 export the SHELL environment variable to the child.
1433 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1435 * config.h.W32: Include sys/types.h.
1436 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1438 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH

1452 * remake.c (f_mtime): Print time difference values between 100 and
1453 ULONG_MAX in fixed-point notation rather than in exponention notation.
1455 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1457 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1458 a more complex value than a simple shell: if it's not a default
1459 shell now then expand it and see if is a default shell then.
1461 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1463 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1464 pathnames, with const strings.
1465 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1466 from the template (used for building from CVS, not a dist).
1468 2007-10-10 Paul Smith <psmith@gnu.org>
1470 * make.h: Add a prototype for w32_kill() (change suggested by
1471 Yongwei Wu <wuyongwei@gmail.com>).
1473 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1475 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1476 directories in Path.
1478 2007-09-12 Paul Smith <psmith@gnu.org>

1481 Provided by Diego Biurrun <diego@biurrun.de>
1482 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1483 Provided by Diego Biurrun <diego@biurrun.de>
1485 2007-09-11 Paul Smith <psmith@gnu.org>
1487 * doc/make.texi (Special Variables): Moved this into the "How to
1488 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1489 (MAKEFILE_LIST) No longer a section; this was added into the
1490 "Special Variables" section.
1491 (Rule Introduction): Reference .RECIPEPREFIX.
1492 (Simple Makefile): Ditto.
1493 (Rule Syntax): Ditto.
1494 (Command Syntax): Ditto.
1495 (Error Messages): Ditto.
1497 2007-09-10 Paul Smith <psmith@gnu.org>
1499 * commands.c (print_commands): Don't print an extra line in the
1500 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1502 * read.c (construct_include_path): Add the full string to the cache; we
1503 were chopping the last char.
1505 * NEWS: Announce the .RECIPEPREFIX special variable.
1506 * variable.c (lookup_special_var): Rename from handle_special_var().
1507 (lookup_variable): Call the new name.
1508 (set_special_var): New function: handle setting of special variables.
1509 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1510 (do_variable_definition): Call it.
1511 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1512 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1513 * main.c (main): Create the .RECIPEPREFIX special variable.
1514 * read.c (eval): Remove the cmd_prefix characters from the command
1515 scripts here, so they're not stored in the commands array at all,
1516 rather than waiting and stripping them out during command construction.
1517 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1519 2007-08-15 Paul Smith <psmith@gnu.org>
1521 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1522 file has had the section info removed, so add some to make.texi
1523 before we include it.
1525 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1527 * remake.c (check_dep): Reset the target state for intermediate
1528 files. They might have been considered before but not updated
1529 then (order-only for example) but they will be this time.
1530 Fixes Savannah bug #'s 3330 and 15919.
1532 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1534 Fix Savannah bug #20549:
1535 * function.c (func_shell): Call construct_command_argv with zero
1537 * job.c (construct_command_argv_internal): New argument FLAGS; all
1539 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1541 * job.h (construct_command_argv_internal): Update prototype.
1543 2007-07-13 Paul Smith <psmith@gnu.org>
1545 * file.c (expand_deps): Use variable_buffer as the start of the
1546 buffer, not the original pointer (in case it was reallocated).
1547 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1548 Fixes Savannah bug #20452.
1550 2007-07-04 Paul Smith <psmith@gnu.org>
1552 * (ALL FILES): Update to GPLv3.
1553 * (ALL FILES): Update copyright for 2007.

1557 2007-06-29 Thiemo Seufer <ths@mips.com>
1559 * maintMakefile: Update Translation Project location.
1561 2007-06-13 Paul Smith <psmith@gnu.org>
1563 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1564 "Expansion of a deferred"
1565 Fixes Savannah bug #20018.
1567 * expand.c (variable_expand_for_file): Preserve the value of
1568 reading_file rather than setting it to 0 at the end.

1587 2007-05-08 Paul Smith <psmith@gnu.org>
1589 Fix Savannah bug #19656:
1591 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1593 * make.h: Change all case-insensitive string compares to use
1594 strcasecmp() (from POSIX). If we don't have that but do have one
1595 of the others, define strcasecmp to be one of those instead. If
1596 we don't have any, declare a prototype for our own version.
1598 * misc.c (strcasecmp): Use this if we can't find any native
1599 case-insensitive string comparison function.
1600 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1601 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1603 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1604 strcasecmp() instead of stricmp().
1605 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1606 instead of strcmpi().
1607 * acinclude.m4: Remove the strcasecmp() check from here.
1609 2007-03-21 Paul Smith <psmith@gnu.org>
1611 * configure.in: Don't turn on case-insensitive file system support
1612 if --disable-... is given. Fixes Savannah bug #19348.
1614 2007-03-19 Paul Smith <psmith@gnu.org>
1616 * ALL: Use the strcache for all file name strings, or other
1617 strings which we will never free. The goal is to save memory by
1618 avoiding duplicate copies of strings. However, at the moment this
1619 doesn't save much memory in most situations: due to secondary
1620 expansion we actually save prerequisite lists twice (once before
1621 the secondary expansion, and then again after it's been parsed
1622 into individual file names in the dep list). We will resolve this
1623 in a future change, by doing the parsing up-front for targets
1624 where secondary expansion is not set.
1626 Moving things into the strcache also allows us to use const
1627 pointers in many more places.
1629 2007-01-03 Paul Smith <psmith@gnu.org>
1631 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1632 the function, not just the first. Fixes Savannah bug #18680.
1634 2006-11-18 Paul Smith <psmith@gnu.org>
1636 * strcache.c (strcache_add_len): Don't allocate a new buffer
1637 unless the string is not already nil-terminated. Technically this
1638 is a violation of the standard, since we may be passed an array
1639 that is not long enough to test one past. However, in make this
1640 is never true since we only use nil-terminated strings or
1641 sub-strings thereof.
1643 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1645 * main.c: New global cmd_prefix, defaults to '\t'.
1646 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1649 * dir.c: Constified.
1650 (dir_contents_file_exists_p): Check for an error return from
1651 readdir(), just in case.
1653 * commands.c: Constified.
1654 * default.c: Constified.
1655 * expand.c: Constified.
1656 * function.c: Partial constification.

1661 * w32/pathstuff.c: Partial constification.
1663 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1665 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1666 backslashes and drive letters as absolute.
1668 2006-10-22 Paul Smith <psmith@gnu.org>

1672 2006-10-21 Paul Smith <psmith@gnu.org>
1675 * arscan.c: Constified.
1677 2006-09-30 Paul Smith <psmith@gnu.org>
1679 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1680 point to lastword since the example was updated.
1681 Fixes Savannah bug #16304.
1682 (Secondary Expansion): Correct example description.
1683 Fixes Savannah bug #16468.
1684 (Makefile Contents): Clarify that comments cannot appear within
1685 variable references or function calls.
1686 Fixes Savannah bug #16577.
1687 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1688 Fixes Savannah bug #17701.

1691 prerequisites. Fixes Savannah bug #17880.
1692 (Rule Syntax): "lise" -> "list"
1693 (Multiple Rules): ... -> @dots{}
1694 (Splitting Lines): ditto.

1740 that don't have extended grep.
1741 (cvsclean): Use $(PERL) instead of perl.

1745 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1747 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1748 inner-scope variables don't mask outer-scope variables.

1811 2006-03-23 Paul D. Smith <psmith@gnu.org>
1813 * configure.in: Look for build.sh.in in $srcdir so it will be
1814 built for remote configurations as well.
1816 * Makefile.am: Make sure to clean up build.sh during distclean.
1817 Fixes Savannah bug #16166.
1819 * misc.c (log_access): Takes a const char *.

1825 * implicit.c (pattern_search): Call set_file_variables only
1826 if we have prerequisites that need second expansion. Fixes
1827 Savannah bug #16140.
1829 2006-03-19 Paul D. Smith <psmith@gnu.org>

1847 allow multiple concurrent runs.
1848 Patch from Joseph Myers <joseph@codesourcery.com>
1850 2006-03-17 Boris Kolpackov <boris@kolpackov.net>

1854 (copy_dep_chain): Copy stem.
1855 (free_dep_chain): Use free_dep.
1856 * read.c (record_files): Store stem in the dependency line.
1857 * file.c (expand_deps): Use stem stored in the dependency line. Use
1858 free_dep_chain instead of free_ns_chain.

1871 Fixes Savannah bug #15913.
1873 2006-03-09 Paul Smith <psmith@gnu.org>
1875 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1876 listed non-existent files as changed. Turns out there's a bug in
1877 the Linux kernel builds which means that this change causes
1878 everything to rebuild every time. We will re-introduce this fix
1879 in the next release, to give them time to fix their build system.
1880 Fixes Savannah bug #16002.
1881 Introduces Savannah bug #16051.

1900 * commands.c (set_file_variables): Realloc, not malloc, the static
1901 string values to avoid memory leaks.
1903 * expand.c (recursively_expand_for_file): Only set reading_file to
1904 an initialized value.
1906 * implicit.c (pattern_search): We need to make a copy of the stem
1907 if we get it from an intermediate dep, since those get freed.
1909 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1911 (enter_file) [VMS]: Ditto.

1918 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1919 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1920 the calls to _beginthreadex.
1922 * expand.c (recursively_expand_for_file): Initialize `save' to
1923 prevent compiler warnings.
1925 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1927 * job.c (construct_command_argv_internal): Don't create a temporary
1928 script/batch file if we are under -n. Call _setmode to switch the
1929 script file stream to text mode.

1933 * variable.c (merge_variable_set_lists): Don't try to merge the
1934 global_setlist. Not only is this useless, but it can lead to
1935 circularities in the linked list, if global_setlist->next in one
1936 list gets set to point to another list which also ends in

1940 2006-02-15 Paul D. Smith <psmith@gnu.org>
1942 Fix for Savannah bug #106.
1944 * expand.c (expanding_var): Keep track of which variable we're
1945 expanding. If no variable is being expanded, it's the same as
1947 * make.h (expanding_var): Declare it.
1948 * expand.c (recursively_expand_for_file): Set expanding_var to the
1949 current variable we're expanding, unless there's no file info in
1950 it (could happen if it comes from the command line or a default
1951 variable). Restore it before we exit.

1963 * read.c (eval): Even if the included filenames expands to the
1964 empty string we still need to free the allocated buffer.
1966 * implicit.c (pattern_search): If we allocated a variable set for
1967 an impossible file, free it.
1968 * variable.c (free_variable_set): New function.
1969 * variable.h: Declare it.
1971 * read.c (read_all_makefiles): Makefile names are kept in the
1972 strcache, so there's never any need to alloc/free them.
1975 * main.c (main): Add "archives" to the .FEATURES variable if
1976 archive support is enabled.
1977 * doc/make.texi (Special Variables): Document it.

1987 * (ALL FILES): Updated copyright and license notices.
1989 2006-02-10 Paul D. Smith <psmith@gnu.org>
1991 A new internal capability: the string cache is a read-only cache
1992 of strings, with a hash table interface for fast lookup. Nothing
1993 in the cache will ever be freed, so there's no need for reference
1994 counting, etc. This is the beginning of a full solution for
1995 Savannah bug #15182, but for now we only store makefile names here.
1997 * strcache.c: New file. Implement a read-only string cache.
1998 * make.h: Add prototypes for new functions.
1999 * main.c (initialize_global_hash_tables): Initialize the string cache.
2000 (print_data_base): Print string cache stats.
2001 * read.c (eval_makefile): Use the string cache to store makefile
2002 names. Rewrite the string allocation to be sure we free everything.

2006 * dir.c (dir_contents_file_exists_p): Don't opendir if the
2007 directory time stamp didn't change, except on FAT filesystems.

2032 -W, don't overwrite it with the real mtime.

2051 * filedef.h (struct file): Add a new LAST pointer.
2053 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
2054 the comparison. For 64-bits systems the result of the subtraction
2055 might not fit into an int. Use comparison instead.
2056 Fixes Savannah bug #15534.
2058 * doc/make.texi: Update the chapter on writing commands to reflect
2059 the changes made in 3.81 for backslash/newline and SHELL handling.
2061 2006-02-01 Paul D. Smith <psmith@gnu.org>
2063 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
2064 variable st is not used when it's not initialized.

2079 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2081 * remake.c (update_goal_chain): Set g->changed instead of
2082 incrementing it, as it is only 8-bit wide, and could overflow if

2090 array to MAXIMUM_WAIT_OBJECTS.
2091 (process_used_slots): New function.
2092 (process_register): Don't register more processes than the
2093 available number of slots.
2094 (process_easy): Don't start new processes if all slots are used up.
2096 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
2097 are already more children than sub_proc.c can handle, behave as if
2098 the load were too high.
2099 (start_job_command): Fix a typo in error message when process_easy
2102 2006-01-14 Eli Zaretskii <eliz@gnu.org>
2104 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
2105 the shell is not sh.exe.
2107 * job.c (create_batch_file): Renamed from create_batch_filename;
2108 all callers changed. Don't close the temporary file; return its
2109 file descriptor instead. New arg FD allows to return the file
2111 (construct_command_argv_internal): Use _fdopen instead of fopen to
2112 open the batch file.
2114 2006-01-04 Paul D. Smith <psmith@gnu.org>
2116 * readme.vms: Updates for case-insensitive VMS file systems from
2117 Hartmut Becker <Hartmut.Becker@hp.com>.
2118 * dir.c (vms_hash): Ditto.
2119 * vmsify.c (copyto): Ditto.
2120 * vmsfunctions.c (readdir): Ditto.
2122 * make.1: Add a section on the exit codes for make.
2124 * doc/make.texi: A number of minor updates to the documentation.
2126 2006-01-03 Paul D. Smith <psmith@gnu.org>
2128 * remake.c (update_file_1): Mark a prerequisite changed if it
2131 * read.c (eval): Be sure to strip off trailing whitespace from the
2132 prerequisites list properly. Also, initialize all fields in
2133 struct dep when creating a new one.
2135 2005-12-28 Paul D. Smith <psmith@gnu.org>
2137 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2138 disable warnings for MSC.
2139 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2141 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2143 * doc/make.texi (Execution): Add a footnote about changes in
2144 handling of backslash-newline sequences. Mention the differences
2145 on MS-DOS and MS-Windows.
2147 * NEWS: More details about building the MinGW port and a pointer
2148 to README.W32. Fix the section name that describes the new
2149 backward-incompatible processing of backslash-newline sequences.
2150 The special processing of SHELL set to "cmd" is only relevant to
2151 MS-Windows, not MS-DOS.
2153 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2155 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2156 to DWORD, to avoid compiler warnings.
2157 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2158 use %ld in format, to avoid compiler warnings.
2160 * doc/make.texi (Special Targets): Fix a typo.
2161 (Appending): Fix cross-reference to Setting.
2162 (Special Variables, Secondary Expansion, File Name Functions)
2163 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2164 periods after a sentence.
2165 (Execution): Add @: after "e.g.".
2166 (Environment): Fix punctuation.
2167 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2168 (Shell Function, Target-specific): Add @: after "vs."
2170 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2172 * read.c (record_target_var): Initialize variable's export field
2173 with v_default instead of leaving it "initialized" by whatever
2174 garbage happened to be on the heap.
2176 2005-12-12 Paul D. Smith <psmith@gnu.org>
2178 * make.1: Fix some display errors and document all existing options.
2179 Patch by Mike Frysinger <vapier@gentoo.org>.
2181 2005-12-11 Paul D. Smith <psmith@gnu.org>
2183 * implicit.c (pattern_search): If 2nd expansion is not set for
2184 this implicit rule, replace the pattern with the stem directly,
2185 and don't re-expand the variable list. Along with the other
2186 .SECONDEXPANSION changes below, fixes bug #13781.
2188 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2190 * implicit.c (pattern_search): Mark other files that this rule
2191 builds as targets so that they are not treated as intermediates
2192 by the pattern rule search algorithm. Fixes bug #13022.
2194 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2196 * remake.c (notice_finished_file): Propagate the change of
2197 modification time to all the double-colon entries only if
2198 it is the last one to be updated. Fixes bug #14334.
2200 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2202 * function.c (func_flavor): Implement the flavor function which
2203 returns the flavor of a variable.
2204 * doc/make.texi (Functions for Transforming Text): Document it.
2205 * NEWS: Add it to the list of new functions.
2207 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2209 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2211 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2212 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2214 2005-10-26 Paul Smith <psmith@gnu.org>
2216 * read.c (record_files): Don't set deps flags if there are no deps.
2217 * maintMakefile: We only need to build the templates when we are
2218 creating a distribution, so don't do it for "all".
2220 2005-10-24 Paul D. Smith <psmith@gnu.org>
2222 Make secondary expansion optional: its enabled by declaring the
2223 special target .SECONDEXPANSION.
2225 * NEWS: Update information on second expansion capabilities.
2226 * doc/make.texi (Secondary Expansion): Document the
2227 .SECONDEXPANSION special target and its behavior.
2228 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2229 prerequisite list was found in a static pattern rule.
2230 (free_dep_chain): Declare a prototype.
2231 * file.c (parse_prereqs): New function: break out some complexity
2233 (expand_deps): If we aren't doing second expansion, replace % with
2234 the stem for static pattern rules. Call the new function.
2235 * filedef.h (parse_prereqs): Declare a prototype.
2236 * implicit.c (pattern_search): Initialize the new staticpattern
2238 * main.c (second_expansion): Declare a global variable to remember
2239 if the special target has been seen. Initialize the new
2240 staticpattern field for prerequisites.
2241 * make.h: Extern for second_expansion.
2242 * misc.c (free_dep_chain): New function: frees a struct dep list.
2243 * read.c (read_all_makefiles): Initialize the staticpattern field.
2244 (eval_makefile): Ditto.
2245 (record_files): Check for the .SECONDEXPANSION target and set
2246 second_expansion global if it's found.
2247 Use the new free_dep_chain() instead of doing it by hand.
2248 Set the staticpattern field for prereqs of static pattern targets.
2250 2005-10-16 Paul D. Smith <psmith@gnu.org>
2252 * main.c (main): Set CURDIR to be a file variable instead of a
2253 default, so that values of CURDIR inherited from the environment
2254 won't override the make value.
2256 2005-09-26 Paul D. Smith <psmith@gnu.org>
2258 * job.c (construct_command_argv_internal): If the line is empty
2259 remember to free the temporary argv strings.
2262 2005-09-16 Paul D. Smith <psmith@gnu.org>
2264 * job.c (start_job_command): The noerror flag is a boolean (single
2265 bit); set it appropriately.
2266 Reported by Mark Eichin <eichin@metacarta.com>
2268 2005-08-29 Paul D. Smith <psmith@gnu.org>
2270 * function.c (func_error): On Windows, output from $(info ...)
2271 seems to come in the wrong order. Try to force it with fflush().
2273 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2275 * read.c (record_files): Move code that sets stem for static
2276 pattern rules out of the if (!two_colon) condition so it is
2277 also executed for two-colon rules. Fixes Savannah bug #13881.
2279 2005-08-08 Paul D. Smith <psmith@gnu.org>
2281 * make.h: Don't test that __STDC__ is non-0. Some compilers
2282 (Windows for example) set it to 0 to denote "ISO C + extensions".
2285 2005-08-07 Paul D. Smith <psmith@gnu.org>
2287 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2288 conditional (slightly different version of a fix from Eli).
2290 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2291 If make is running in parallel without -k and two jobs die in a
2292 row, but not too close to each other, then make will quit without
2293 waiting for the rest of the jobs to die.
2295 * main.c (die): Don't reset err before calling reap_children() the
2296 second time: we still want it to be in the error condition.
2297 * job.c (reap_children): Use a static variable, rather than err,
2298 to control whether or not the error message should be printed.
2300 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2302 * w32/subproc/sub_proc.c: Include signal.h.
2303 (process_pipe_io, process_file_io): Pass a pointer to a local
2304 DWORD variable to GetExitCodeProcess. If the exit code is
2305 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2307 * job.c [WINDOWS32]: Include windows.h.
2308 (main_thread) [WINDOWS32]: New global variable.
2309 (reap_children) [WINDOWS32]: Get the handle for the main thread
2310 and store it in main_thread.
2312 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2313 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2314 doing anything else. When we are done, close the main thread
2315 handle and exit with status 130.
2317 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2319 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2322 * main.c (find_and_set_default_shell): If found a DOSish shell,
2323 set sh_found and the value of default_shell, and report the
2324 findings in debug mode.
2326 * job.c (construct_command_argv_internal): Check unixy_shell, not
2327 no_default_sh_exe, to decide whether to use Unixy or DOSish
2330 * README.W32: Update with info about the MinGW build.
2332 * build_w32.bat: Support MinGW.
2334 * w32/subproc/build.bat: Likewise.
2336 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2337 printing DWORD args.
2339 * function.c (windows32_openpipe): Fix format strings for printing
2342 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2344 (start_job_command): Fix format string for printing the result of
2346 (start_job_command) [WINDOWS32]: Do not define.
2347 (exec_command): Fix format string for printing HANDLE args.
2349 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2350 to avoid compiler warnings.
2351 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2352 (Note: some of these fixes were submitted independently by J. Grant)
2354 2005-07-30 J. Grant <jg@jguk.org>
2356 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2357 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2358 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2360 2005-07-15 Paul Smith <psmith@gnu.org>
2362 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2363 we don't have a POSIX shell, then revert to the old
2364 backslash-newline behavior (where they are stripped).
2367 2005-07-08 Paul D. Smith <psmith@gnu.org>
2369 * config.h.W32.template: Reorder to match the standard config.h,
2370 for easier comparisons.
2371 From J. Grant <jg@jguk.org>
2373 * maintMakefile: Remove .dep_segment before overwriting it, in
2374 case it's not writable or noclobber is set.
2375 * expand.c (variable_expand_string): Cast result of pointer
2376 arithmetic to avoid a warning.
2377 * main.c (switches): Add full-fledged final initializer.
2379 2005-07-06 Paul D. Smith <psmith@gnu.org>
2381 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2382 * signame.c (strsignal): If we found _sys_siglist[] or
2383 __sys_siglist[] use those instead of sys_siglist[].
2384 From Albert Chin <china@thewrittenword.com>
2386 2005-07-04 Paul D. Smith <psmith@gnu.org>
2388 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2389 globfree(); set up to use the GNU versions.
2390 From Martin Zinser <zinser@zinser.no-ip.info>
2392 2005-07-03 Paul D. Smith <psmith@gnu.org>
2394 From J. Grant <jg@jguk.org>:
2396 * README.W32.template: Update the Windows and tested MSVC versions.
2397 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2398 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2399 * build_w32.bat: Ditto.
2400 * w32/subproc/build.bat: Ditto.
2402 2005-06-28 Paul D. Smith <psmith@gnu.org>
2404 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2405 declaration was checked but not present.
2407 2005-06-27 Paul D. Smith <psmith@gnu.org>
2409 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2410 to unsigned long. Fixes Savannah bug #13550.
2412 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2413 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2414 Fixes Savannah bug #13551.
2416 2005-06-26 Paul D. Smith <psmith@gnu.org>
2418 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2419 it if ANSI_STRING is not set.
2421 2005-06-25 Paul D. Smith <psmith@gnu.org>
2423 * read.c (eval): If no filenames are passed to any of the
2424 "include" variants, don't print an error.
2425 * doc/make.texi (Include): Document this.
2426 Fixes Savannah bug #1761.
2428 * job.c (construct_command_argv_internal): Sanitize handling of
2429 backslash/newline pairs according to POSIX: that is, keep the
2430 backslash-newline in the command script, but remove a following
2431 TAB character, if present. In the fast path, make sure that the
2432 behavior matches what the shell would do both inside and outside
2433 of quotes. In the slow path, quote the backslash and put a
2434 literal newline in the string.
2435 Fixes Savannah bug #1332.
2436 * doc/make.texi (Execution): Document the new behavior and give
2438 * NEWS: Make a note of the new behavior.
2440 * make.h [WINDOWS32]: #include <direct.h>.
2441 Fixes Savannah bug #13478.
2443 * remake.c (name_mtime): If the stat() of a file fails and the -L
2444 option was given and the file is a symlink, take the best mtime of
2445 the symlink we can get as the mtime of the file and don't fail.
2446 Fixes Savannah bug #13280.
2448 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2449 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2450 inside a variable reference. Make this function static as it's
2452 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2453 parsing an unexpanded line looking for semicolons.
2454 Fixes Savannah bug #1454.
2455 * misc.c (remove_comments): Move this to read.c and make it static
2456 as it's only used there. Call find_char_unquote() with new arg.
2457 * make.h: Remove prototypes for find_char_unquote() and
2458 remove_comments() since they're static now.
2460 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2461 its export flag and obtain its value. When we need to re-exec,
2462 increment the value and add it into the environment.
2463 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2464 * NEWS: Mention MAKE_RESTARTS.
2465 * main.c (always_make_set): New variable. Change the -B option to
2466 set this one instead.
2467 (main): When checking makefiles, only set always_make_flag if
2468 always_make_set is set AND the restarts flag is 0. When building
2469 normal targets, set it IFF always_make_set is set.
2470 (main): Avoid infinite recursion with -W, too: only set what-if
2471 files to NEW before we check makefiles if we've never restarted
2472 before. If we have restarted, set what-if files to NEW _after_ we
2474 Fixes Savannah bug #7566:
2476 2005-06-17 Paul D. Smith <psmith@gnu.org>
2478 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2479 in the prerequisites list.
2481 2005-06-12 Paul D. Smith <psmith@gnu.org>
2483 Fix Savannah bug # 1328.
2485 * configure.in: Check for atexit().
2486 * misc.c (close_stdout): Test stdout to see if writes to it have
2487 failed. If so, be sure to exit with a non-0 error code. Based on
2488 code found in gnulib.
2489 * make.h: Prototype.
2490 * main.c (main): Install close_stdout() with atexit().
2492 2005-06-10 Paul D. Smith <psmith@gnu.org>
2494 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2496 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2497 headers; make vmsWaitForChildren() static; extern vmsify().
2498 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2499 Don't create child_execute_job() here (it's in vmsjobs.c).
2500 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2502 2005-06-09 Paul D. Smith <psmith@gnu.org>
2504 * variable.c (push_new_variable_scope): File variables point
2505 directly to the global_setlist variable. So, inserting a new
2506 scope in front of that has no effect on those variables: they
2507 don't go through current_variable_set_list. If we're pushing a
2508 scope and the current scope is global, push it "the other way" so
2509 that the new setlist is in the global_setlist variable, and
2510 next points to a new setlist with the global variable set.
2511 (pop_variable_scope): Properly undo a push with the new
2513 Fixes Savannah bug #11913.
2515 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2517 * job.c (reap_children): Don't die of the command failed but
2518 the dontcare flag is set. Fixes Savannah bug #13216.
2520 * implicit.c (pattern_search): When creating a target from
2521 an implicit rule match, lookup pattern target and set precious
2522 flag in a newly created target. Fixes Savannah bug #13218.
2524 2005-05-13 Paul D. Smith <psmith@gnu.org>
2526 Implement "if... else if... endif" syntax.
2528 * read.c (eval): Push all checks for conditional words ("ifeq",
2529 "else", etc.) down into the conditional_line() function.
2530 (conditional_line): Rework to allow "else if..." clause. New
2531 return value -2 for lines which are not conditionals. The
2532 ignoring flag can now also be 2, which means "already parsed a
2533 true branch". If that value is seen no other branch of this
2534 conditional can be considered true. In the else parsing if there
2535 is extra text after the else, invoke conditional_line()
2536 recursively to see if it's another conditional. If not, it's an
2537 error. If so, raise the conditional value to this level instead
2538 of creating a new conditional nesting level. Special check for
2539 "else" and "endif", which aren't allowed on the "else" line.
2540 * doc/make.texi (Conditional Syntax): Document the new syntax.
2542 2005-05-09 Paul D. Smith <psmith@gnu.org>
2544 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2545 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2546 recurses to the w32 directory, even on non-Windows systems. Use
2547 the method suggested in the automake manual.
2548 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2549 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2551 2005-05-07 Paul D. Smith <psmith@gnu.org>
2553 * main.c (die): If we're dying with a fatal error (not that a
2554 command has failed), write back any leftover tokens before we go.
2556 * job.c (set_child_handler_action_flags): If there are jobs
2557 waiting for the load to go down, set an alarm to go off in 1
2558 second. This allows us to wake up from a potentially long-lasting
2559 read() and start a new job if the load has gone down. Turn it off
2561 (job_noop): Dummy signal handler function.
2562 (new_job): Invoke it with the new semantics.
2564 * docs/make.texi: Document secondary expansion. Various cleanups
2567 2005-05-03 Paul D. Smith <psmith@gnu.org>
2569 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2570 the targets which are to ultimately be made are called "goals";
2571 see the GNU make manual. Also, MAKECMDGOALS, etc.
2573 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2574 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2575 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2577 2005-05-02 Paul D. Smith <psmith@gnu.org>
2579 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2580 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2581 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2582 functions to vmsjobs.c. #include it into jobs.c.
2584 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2585 jobserver tokens. I found that this happens when an exported
2586 recursive variable contains a $(shell ...) function reference: in
2587 this situation we could "forget" to write back a token.
2589 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2590 we have. It's not reliable to depend on the number of children in
2591 our linked list so keep a separate count.
2592 (new_job): Check jobserver_tokens rather than children &&
2593 waiting_jobs. Increment jobserver_tokens when we get one.
2594 (free_child): If jobserver_tokens is 0, internal error. If it's
2595 >1, write a token back to the jobserver pipe (we don't write a
2596 token for the "free" job). Decrement jobserver_tokens.
2598 * main.c: Add variable master_job_slots.
2599 (main): Set it to hold the number of jobs requested if we're the
2600 master process, when using the jobserver.
2601 (die): Sanity checks: first test jobserver_tokens to make sure
2602 this process isn't holding any tokens we didn't write back.
2603 Second, if master_job_slots is set count the tokens left in the
2604 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2606 2005-04-24 Paul D. Smith <psmith@gnu.org>
2608 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2609 with -l# can lose jobserver tokens, because waiting jobs are not
2610 consulted properly when checking for the "free" token.
2612 * job.c (free_child): Count waiting_jobs as having tokens.
2613 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2614 handle jobs waiting for the load to drop.
2616 2005-04-23 Paul D. Smith <psmith@gnu.org>
2618 * main.c (main): Be careful to not core if a variable setting in
2619 the environment doesn't contain an '='. This is illegal but can
2620 happen in broken setups.
2621 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2623 2005-04-12 Paul D. Smith <psmith@gnu.org>
2625 The second expansion feature causes significant slowdown. Timing
2626 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2627 read the makefile before the feature, to 11+s to do the same
2628 operations after the feature. Additionally, memory usage
2629 increased drastically. To fix this I added some intelligence that
2630 avoids the overhead of the second expansion unless it's required.
2632 * dep.h: Add a new boolean field, need_2nd_expansion.
2634 * read.c (eval): When creating the struct dep for the target,
2635 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2636 (record_files): If there's a "%" in a static pattern rule, it gets
2637 converted to "$*" so set need_2nd_expansion to 1.
2639 * file.c (expand_deps): Rework to be more efficient. Only perform
2640 initialize_file_variables(), set_file_variables(), and
2641 variable_expand_for_file() if the need_2nd_expansion is set.
2643 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2644 (pattern_search): Ditto.
2645 * main.c (handle_non_switch_argument): Ditto.
2647 * read.c (read_all_makefiles): Ditto.
2648 (eval_makefile): Ditto.
2650 2005-04-07 Paul D. Smith <psmith@gnu.org>
2652 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2653 * variable.c (sync_Path_environment): Ditto.
2654 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2656 * main.c (main): Define the .FEATURES variable.
2657 * NEWS: Announce .FEATURES.
2658 * doc/make.texi (Special Variables): Document .FEATURES.
2660 * remake.c (check_dep): If a file is .PHONY, update it even if
2661 it's marked intermediate. Fixes Savannah bug #12331.
2663 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2665 * file.c (expand_deps): Factor out the second expansion and
2666 prerequisite line parsing logic from snap_deps().
2668 * file.c (snap_deps): Use expand_deps(). Expand and parse
2669 prerequisites of the .SUFFIXES special target first. Fixes
2670 Savannah bug #12320.
2672 2005-03-13 Paul D. Smith <psmith@gnu.org>
2674 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2677 2005-03-11 Paul D. Smith <psmith@gnu.org>
2679 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2680 available, not undefined (from Earnie Boyd).
2682 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2684 * implicit.c (pattern_search): Mark an intermediate target as
2685 precious if it happened to be a prerequisite of some (other)
2686 target. Fixes Savannah bug #12267.
2688 2005-03-09 Paul D. Smith <psmith@gnu.org>
2690 * read.c (eval_makefile): Add alloca(0).
2691 (eval_buffer): Ditto.
2693 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2695 * main.c (main): Use o_file instead of o_default when defining
2696 the .DEFAULT_TARGET special variable.
2697 * read.c (eval): Use define_variable_global() instead of
2698 define_variable() when setting new value for the .DEFAULT_TARGET
2699 special variable. Fixes Savannah bug #12266.
2701 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2703 * imlicit.c (pattern_search): Mark files for which an implicit
2704 rule has been found as targets. Fixes Savannah bug #12202.
2706 2005-03-04 Paul D. Smith <psmith@gnu.org>
2709 * doc/make.texi (Automatic Variables): Document $|.
2711 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2713 * read.c (record_files): Instead of substituting % with
2714 actual stem value in dependency list replace it with $*.
2715 This fixes stem triple expansion bug.
2717 * implicit.c (pattern_search): Copy stem to a separate
2718 buffer and make it a properly terminated string. Assign
2719 this buffer instead of STEM (which is not terminated) to
2720 f->stem. Instead of substituting % with actual stem value
2721 in dependency list replace it with $*. This fixes stem
2722 triple expansion bug.
2724 2005-03-01 Paul D. Smith <psmith@gnu.org>
2726 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2727 on Windows, as it takes a handle not a pid. Just exit.
2728 Fix from patch #3679, provided by Alessandro Vesely.
2730 * configure.in: Update check for sys_siglist[] from autoconf manual.
2731 * signame.c (strsignal): Update to use the new autoconf macro.
2733 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2735 * read.c (record_files): Add a check for the list of prerequisites
2736 of a static pattern rule being empty. Fixes Savannah bug #12180.
2738 2005-02-28 Paul D. Smith <psmith@gnu.org>
2740 * doc/make.texi (Text Functions): Update docs to allow the end
2741 ordinal for $(wordlist ...) to be 0.
2742 * function.c (func_wordlist): Fail if the start ordinal for
2743 $(wordlist ...) is <1. Matches documentation.
2744 Resolves Savannah support request #103195.
2746 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2747 previously we were stopping when !-q, exactly the opposite. This
2748 has been wrong since version 1.34, in 1994!
2749 (update_file): If we got an error don't break out to run more
2750 double-colon rules: just return immediately.
2751 Fixes Savannah bug #7144.
2753 2005-02-27 Paul D. Smith <psmith@gnu.org>
2755 * misc.c (end_of_token): Make argument const.
2756 * make.h: Update prototype.
2758 * function.c (abspath, func_realpath, func_abspath): Use
2759 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2760 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2761 * read.c (record_files): Ditto.
2762 * variable.c (do_variable_definition): Ditto.
2764 * function.c (func_error): Create a new function $(info ...) that
2765 simply prints the message to stdout with no extras.
2766 (function_table_init): Add new function to the table.
2767 * NEWS: Add $(info ...) reference.
2768 * doc/make.texi (Make Control Functions): Document it.
2770 New feature: if the system supports symbolic links, and the user
2771 provides the -L/--check-symlink-time flag, then use the latest
2772 mtime between the symlink(s) and the target file.
2774 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2775 readlink(). If both are available, define MAKE_SYMLINKS.
2776 * main.c: New variable: check_symlink_flag.
2777 (usage): Add a line for -L/--check-symlink-times to the help string.
2778 (switches): Add -L/--check-symlink-times command line argument.
2779 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2780 print a warning and disable it again.
2781 * make.h: Declare check_symlink_flag.
2782 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2783 if the file is a symlink then check each link in the chain and
2784 choose the NEWEST mtime we find as the mtime for the file. The
2785 newest mtime might be the file itself!
2786 * NEWS: Add information about this new feature.
2787 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2789 Avoid core dumps described in Savannah bug # 12124:
2791 * file.c: New variable snapped_deps remember whether we've run
2793 (snap_deps): Set it.
2794 * filedef.h: Extern it.
2795 * read.c (record_files): Check snapped_deps; if it's set then
2796 we're trying to eval a new target/prerequisite relationship from
2797 within a command script, which we don't support. Fatal.
2799 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2801 Implementation of the .DEFAULT_TARGET special variable.
2803 * read.c (eval): If necessary, update default_target_name when
2805 * read.c (record_files): Update default_target_file if
2806 default_target_name has changed.
2807 * main.c (default_target_name): Define.
2808 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2809 default_target_name is set use default_target_file as a root
2811 * filedef.h (default_target_name): Declare.
2812 * dep.h (free_dep_chain):
2813 * misc.c (free_dep_chain): Change to operate on struct nameseq
2814 and change name to free_ns_chain.
2815 * file.c (snap_deps): Update to use free_ns_chain.
2817 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2819 Implementation of the second expansion in explicit rules,
2820 static pattern rules and implicit rules.
2822 * read.c (eval): Refrain from chopping up rule's dependencies.
2823 Store them in a struct dep as a single dependency line. Remove
2824 the code that implements SySV-style automatic variables.
2826 * read.c (record_files): Adjust the code that handles static
2827 pattern rules to expand all percents instead of only the first
2828 one. Reverse the order in which dependencies are stored so that
2829 when the second expansion reverses them again they appear in
2830 the makefile order (with some exceptions, see comments in
2831 the code). Remove the code that implements SySV-style automatic
2834 * file.c (snap_deps): Implement the second expansion and chopping
2835 of dependency lines for explicit rules.
2837 * implicit.c (struct idep): Define an auxiliary data type to hold
2838 implicit rule's dependencies after stem substitution and
2841 * implicit.c (free_idep_chain): Implement.
2843 * implicit.c (get_next_word): Implement helper function for
2844 parsing implicit rule's dependency lines into words taking
2845 into account variable expansion requests. Used in the stem
2848 * implicit.c (pattern_search): Implement the second expansion
2849 for implicit rules. Also fixes bug #12091.
2851 * commands.h (set_file_variables): Declare.
2852 * commands.c (set_file_variables): Remove static specifier.
2854 * dep.h (free_dep_chain): Declare.
2855 * misc.c (free_dep_chain): Implement.
2857 * variable.h (variable_expand_for_file): Declare.
2858 * expand.c (variable_expand_for_file): Remove static specifier.
2860 * make.h (strip_whitespace): Declare.
2861 * function.c (strip_whitespace): Remove static specifier.
2863 2005-02-26 Paul D. Smith <psmith@gnu.org>
2865 * main.c (main): Check for ferror() when reading makefiles from stdin.
2866 Apparently some shells in Windows don't close pipes properly and
2869 2005-02-24 Jonathan Grant <jg@jguk.org>
2871 * configure.in: Add MinGW configuration options, and extra w32 code
2873 * Makefile.am: Add MinGW configuration options, and extra w32 code
2875 * main.c: Determine correct program string (after last \ without .exe).
2876 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2878 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2879 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2880 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2881 environment support.
2883 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2885 * function.c (func_shell): When initializing error_prefix, check
2886 that reading file name is not null. This fixes long-standing
2887 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2889 2005-02-09 Paul D. Smith <psmith@gnu.org>
2891 * maintMakefile: Update the CVS download URL to simplify them.
2892 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2893 downloading the .texi files from Savannah now.
2895 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2897 * main.c (handle_non_switch_argument): Only add variables to
2898 command_variables if they're not already there: duplicate settings
2899 waste space and can be confusing to read.
2901 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2902 this header is never included by non-WINDOWS32 code, and it
2903 requires <config.h> to define which isn't always included first.
2905 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2906 testing MINGW32 versions.
2908 * main.c (log_working_directory): flush stdout to be sure the WD
2909 change is printed before any stderr messages show up.
2911 2005-02-01 Paul D. Smith <psmith@gnu.org>
2913 * maintMakefile (po_repo): Update the GNU translation site URL.
2915 2004-12-01 Paul D. Smith <psmith@gnu.org>
2917 * main.c (main): Change char* env_shell to struct variable shell_var.
2918 * variable.c (target_environment): Use new shell_var.
2920 2004-11-30 Paul D. Smith <psmith@gnu.org>
2922 * configure.in: The old way we avoided creating build.sh from
2923 build.sh.in before build.sh.in exists doesn't work anymore; we
2924 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2925 the help!). This also keeps automake from complaining.
2926 * Makefile.am (README): Add a dummy target so automake won't
2927 complain that this file doesn't exist when we checkout from CVS.
2928 * maintMakefile (.dep_segment): Rewrite this rule since newer
2929 versions of automake don't provide DEP_FILES.
2931 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2933 Implementation of `realpath' and `abspath' built-in functions.
2935 * configure.in: Check for realpath.
2936 * function.c (abspath): Return an absolute file name that does
2937 not contain any `.' or `..' components, nor repeated `/'.
2938 * function.c (func_abspath): For each name call abspath.
2939 * function.c (func_realpath): For each name call realpath
2940 from libc or delegate to abspath if realpath is not available.
2941 * doc/make.texi (Functions for File Names): Document new functions.
2942 * doc/make.texi (Quick Reference): Ditto.
2944 2004-11-28 Paul D. Smith <psmith@gnu.org>
2946 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2947 arguments. Fixes bug #10252.
2949 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2951 * main.c (main): Set SHELL to v_noexport by default. Remember the
2952 original environment setting of SHELL in the env_shell variable.
2953 * main.h: Export new env_shell variable.
2954 * variable.c (target_environment): If we find a v_noexport
2955 variable for SHELL, add a SHELL variable with the env_shell value.
2956 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2957 * doc/make.texi (Variables/Recursion): Ditto.
2959 2004-11-28 Paul D. Smith <psmith@gnu.org>
2961 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2962 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2963 Patch by Alessandro Vesely.
2965 2004-11-12 Paul D. Smith <psmith@gnu.org>
2967 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2968 the command line if it's inside a string.
2969 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2971 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2973 * function.c (func_lastword): New function: return last word
2974 from the list of words.
2975 * doc/make.texi: Document $(lastword ). Fix broken links in
2976 Quick Reference section.
2978 2004-10-06 Paul D. Smith <psmith@gnu.org>
2980 Apply patch from Alessandro Vesely, provided with bug # 9748.
2981 Fix use of tmpnam() to work with Borland C.
2983 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2984 construction of a temporary filename, and call new function
2985 create_batch_filename().
2986 (create_batch_filename) [WINDOWS32]: New function to create a
2989 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2991 * read.c (record_target_var): Expand simple pattern-specific
2993 * variable.c (initialize_file_variables): Do not expand simple
2994 pattern-specific variable.
2996 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2998 * remake.c (update_file_1): When rebuilding makefiles inherit
2999 dontcare flag from a target that triggered update.
3001 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
3003 * variable.c (initialize_file_variables): Mark pattern-specific
3004 variable as a per-target and copy export status.
3006 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
3008 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
3010 * implicit.c (pattern_search): When considering an implicit rule's
3011 prerequisite check that it is actually a target rather then
3012 just an entry in the file hashtable.
3014 2004-09-21 Paul D. Smith <psmith@gnu.org>
3016 * read.c (readstring): Fix some logic errors in backslash handling.
3017 (eval): Remove some unnecessary processing in buffer handling.
3018 (record_target_var): Assert that parse_variable_definition() succeeded.
3019 Reported by: Markus Mauhart <qwe123@chello.at>.
3021 * misc.c: Removed the sindex() function. All instances of this
3022 function were trivially replaceable by the standard strstr()
3023 function, and that function will always have better (or certainly
3024 no worse) performance than the very simple-minded algorithm
3025 sindex() used. This can matter with complex makefiles.
3026 * make.h: Remove the prototype for sindex().
3027 * function.c (subst_expand): Convert sindex() call to strstr().
3028 This means we no longer need to track the TLEN value so remove that.
3029 (func_findstring): Convert sindex() to strstr().
3030 * commands.c (chop_commands): Convert sindex() calls to strstr().
3031 Suggested by: Markus Mauhart <qwe123@chello.at>.
3033 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
3034 idea behind Savannah Patch #3144 from david.baird@homemail.com.
3035 If SHELL is set to CMD.EXE then assume it's batch-mode and
3036 non-unixy. I wrote the code differently from the patch, though,
3037 to make it safer. This also resolves bug #9174.
3039 2004-09-20 Paul D. Smith <psmith@gnu.org>
3041 * expand.c (variable_expand_string): Modify to invoke
3042 patsubst_expand() instead of subst_expand(); the latter didn't
3043 handle suffix patterns correctly.
3044 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
3045 was used only from variable_expand_string() and is no longer used
3047 (func_subst): Ditto, on call to subst_expand().
3048 (patsubst_expand): Require the percent pointers to point to the
3049 character after the %, not to the % itself.
3050 * read.c (record_files): New call criteria for patsubst_expand().
3051 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
3052 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
3054 2004-09-19 Paul D. Smith <psmith@gnu.org>
3056 * function.c (subst_expand): Fix a check in by_word: look for a
3057 previous blank if we're beyond the beginning of the string, not
3058 the beginning of the word.
3059 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3061 2004-05-16 Paul D. Smith <psmith@gnu.org>
3063 * remake.c (update_goal_chain): Change the argument specifying
3064 whether we're rebuilding makefiles to be a global variable,
3065 REBUILDING_MAKEFILES.
3066 (complain): Extract the code that complains about no rules to make
3067 a target into a separate function.
3068 (update_file_1): If we tried to rebuild a file during the makefile
3069 rebuild phase and it was dontcare, then no message was printed.
3070 If we then try to build the same file during the normal build,
3071 print a message this time.
3072 (remake_file): Don't complain about un-remake-able files when
3073 we're rebuilding makefiles.
3075 2004-05-11 Paul D. Smith <psmith@gnu.org>
3077 * job.c (construct_command_argv_internal): OS/2 patches from
3078 Andreas Buening <andreas.buening@nexgo.de>.
3080 2004-05-10 Paul D. Smith <psmith@gnu.org>
3082 * remake.c (update_file): Don't walk the double-colon chain unless
3083 this is a double-colon rule. Fix suggested by Boris Kolpackov
3084 <boris@kolpackov.net>.
3086 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3087 * readme.vms: New section describing OpenVMS support and issues.
3088 * default.c (default_variables): Add support for IA64.
3089 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3090 without some privilege aborts make with the error
3091 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3092 pressing Ctrl+Y and the input device is no terminal. The change
3093 catches this error and just continues.
3095 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3097 2004-04-25 Paul D. Smith <psmith@gnu.org>
3099 * commands.c (set_file_variables): Set $< properly in the face of
3100 order-only prerequisites.
3101 Patch from Boris Kolpackov <boris@kolpackov.net>
3103 2004-04-21 Bob Byrnes <byrnes@curl.com>
3105 * main.c (main): Notice failures to remake makefiles.
3107 2004-03-28 Paul D. Smith <psmith@gnu.org>
3109 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3111 * job.c: No default shell for RISC OS.
3112 (load_too_high): Hard-code the return to 1.
3113 (construct_command_argv_internal): No sh_chars or sh_cmds.
3114 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3116 2004-03-20 Paul D. Smith <psmith@gnu.org>
3118 * variable.c (do_variable_definition): Don't append from the
3119 global set if a previous non-appending target-specific variable
3120 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3123 * expand.c (reference_variable): Don't give up on variables with
3124 no value that have the target-specific append flag set: they might
3125 have a value after all. Reported by Oliver Schmidt
3126 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3127 <nikulin@dx1cmd.inp.nsk.su>.
3129 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3130 refer to absolute pathnames in directories that don't exist: some
3131 portion of the makefile could create those directories before we
3132 match the pattern. Fixes bugs #775 and #108.
3134 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3136 * main.c (main): Free makefile_mtimes if we have any.
3137 * README.W32.template: Update documentation for the current status
3138 of the MS-Windows port.
3139 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3140 environment variable is sometimes already defined which causes the
3142 * main.c (debug_signal_handler): Only define this function if
3143 SIGUSR1 is available.
3145 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3147 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3148 * README.OS2.template: Documentation updates.
3149 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3150 link line for safety.
3151 * maintMakefile (build.sh.in): Remove an extraneous ")".
3152 * job.c (child_execute_job): Close saved FDs.
3153 * job.c (exec_command) [OS/2]: exec_command(): If the command
3154 can't be exec'ed and if the shell is not Unix-sh, then try again
3155 with argv = { "cmd", "/c", ... }. Normally, this code is never
3156 reached for the cmd shell unless the command really doesn't exist.
3157 (construct_command_argv_internal) [OS/2]: The code for cmd
3158 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3159 The CMD builtin commands are case insensitive so use strcasecmp().
3161 2004-03-19 Paul D. Smith <psmith@gnu.org>
3163 * read.c (do_define): Re-order line counter increment so the count
3164 is accurate (we were losing one line per define). Reported by
3165 Dave Yost <Dave@Yost.com>.
3167 2004-03-06 Paul D. Smith <psmith@gnu.org>
3169 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3171 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3172 * misc.c (message,error,fatal): Ditto.
3173 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3174 * config.h.W32.template: Ditto.
3175 * config.h-vms.template: Ditto.
3176 * config.ami.template: Ditto.
3178 2004-03-04 Paul D. Smith <psmith@gnu.org>
3180 * README.template: Add a note about broken /bin/sh on SunOS
3181 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3183 * misc.c (message, error, fatal): Don't use "..." if we're using
3184 varargs. ansi2knr should handle this but it doesn't work: it
3185 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3186 done. On many systems (SunOS for example) va_dcl is a #define.
3187 So, force the use of the non-"..." version on pre-ANSI compilers.
3189 * maintMakefile (sign-dist): Create some rules to help automate
3190 the new GNU ftp upload method.
3192 2004-02-24 Paul D. Smith <psmith@gnu.org>
3194 * config.h.W32.template: Add HAVE_STDARG_H
3195 * config.h-vms.template: Ditto.
3196 * config.ami.template: Ditto.
3198 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3200 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3201 * build_w32.bat: Remove extra "+".
3203 2004-02-23 Paul D. Smith <psmith@gnu.org>
3205 * make.h: Create an UNUSED macro to mark unused parameters.
3206 * (many): Clean up warnings by applying UNUSED, fixing
3207 signed/unsigned incompatibilities, etc.
3209 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3211 * filedef.h: Name the command_state enumeration.
3212 * file.c (set_command_state): Use the enumeration in the function
3215 * configure.in: Explicitly set SET_MAKE to empty, to disable
3216 MAKE=make even when no make already exists. Fix bug #3823.
3218 2004-02-22 Paul D. Smith <psmith@gnu.org>
3220 * maintMakefile: Perl script to clean up all non-CVS files. Use
3221 it on all the subdirectories for the cvs-clean target.
3223 * main.c (decode_switches): Require non-empty strings for all our
3224 string command-line options. Fixes Debian bug # 164165.
3226 * configure.in: Check for stdarg.h and varargs.h.
3227 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3228 for printing messages.
3229 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3234 A number of patches for OS/2 support from Andreas Buening
3235 <andreas.buening@nexgo.de>:
3237 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3238 disable the SIGCHLD handler.
3239 (reap_children) [OS/2]: Remove special handling of job_rfd.
3240 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3241 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3242 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3243 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3244 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3247 2004-02-21 Paul D. Smith <psmith@gnu.org>
3249 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3250 <mail@kristov.de> reports that if process_begin() fails we don't
3251 handle the error condition correctly in all cases.
3252 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3253 to have a newline on the message.
3255 * job.c (construct_command_argv_internal): Add "test" to UNIX
3256 sh_cmds[]. Fixes Savannah bug # 7606.
3258 2004-02-04 Paul D. Smith <psmith@gnu.org>
3260 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3261 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3262 Hartmut Becker <Hartmut.Becker@hp.com>.
3264 2004-01-21 Paul D. Smith <psmith@gnu.org>
3266 * job.c (load_too_high): Implement an algorithm to control the
3267 "thundering herd" problem when using -l to control job creation
3268 via the load average. The system only recomputes the load once a
3269 second but we can start many jobs in a second. To solve this we
3270 keep track of the number of jobs started in the last second and
3271 apply a weight to try to guess what a correct load would be.
3272 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3273 Also fixes bug #4693.
3274 (reap_children): Decrease the job count for this second.
3275 (start_job_command): Increase the job count for this second.
3277 * read.c (conditional_line): Expand the text after ifn?def before
3278 checking to see if it's a single word. Fixes bug #7257.
3280 2004-01-09 Paul D. Smith <psmith@gnu.org>
3282 * file.c (print_file): Recurse to print all targets in
3283 double-colon rules. Fixes bug #4518, reported (with patch) by
3284 Andrew Chatham <chatham@google.com>.
3286 2004-01-07 Paul D. Smith <psmith@gnu.org>
3288 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3289 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3290 AC_FUNC_SETVBUF_REVERSED.
3292 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3293 (MAKE Variable): Fix Savannah bug #4898.
3295 * job.c (construct_command_argv_internal): Add "!" to the list of
3296 shell escape chars. POSIX sh allows it to appear before a
3297 command, to negate the exit code. Fixes bug #6404.
3299 * implicit.c (pattern_search): When matching an implicit rule,
3300 remember which dependencies have the ignore_mtime flag set.
3301 Original fix provided in Savannah patch #2349, by Benoit
3302 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3304 2003-11-22 Paul D. Smith <psmith@gnu.org>
3306 * README.W32.template (Outputs): Clarification on -j with
3307 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3310 2003-11-02 Paul D. Smith <psmith@gnu.org>
3312 * function.c (func_if): Strip all the trailing whitespace from the
3313 condition, then don't expand it. Fixed bug # 5798.
3315 * expand.c (recursively_expand_for_file): If we're expanding a
3316 variable with no file context, then use the variable's context.
3319 2003-10-21 Paul D. Smith <psmith@gnu.org>
3321 * main.c (log_working_directory): Add newlines to printf()s.
3323 * README.cvs: Add a note to ignore warnings during autoreconf.
3325 * maintMakefile (po_repo): Set a new URL for PO file updates.
3326 (get-config/config.guess get-config/config.sub): Get these files
3327 from the Savannah config project instead of ftp.gnu.org.
3329 2003-10-05 Paul Eggert <eggert@twinsun.com>
3331 * main.c (main): Avoid potential subscript error if environ has
3334 2003-08-22 Paul D. Smith <psmith@gnu.org>
3336 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3337 systems which don't yet implement the C89 standard :-/.
3339 2003-07-18 Paul D. Smith <psmith@gnu.org>
3341 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3342 [WINDOWS32]: Initialize hash.
3344 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3346 * dir.c (read_dirstream): Provide a workaround for broken versions of
3347 the MinGW dirent structure.
3349 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3351 * w32/include/dirent.h: Add __MINGW32__ filter.
3353 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3355 * make.h: Add global declaration of *make_host.
3356 * main.c (print_usage): Remove local declaration of *make_host.
3357 (print_version): Display "This program built for ..." after Copyright
3360 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3362 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3363 execution of "makeinfo --html make.texi".
3365 2003-04-30 Paul D. Smith <psmith@gnu.org>
3367 * build.template: Make some changes to maybe allow this script to
3368 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3370 * README.OS2.template: New file for OS/2 support. Original
3371 contributed by Andreas Buening.
3372 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3375 2003-04-19 Paul D. Smith <psmith@gnu.org>
3377 Fix bug #1405: allow a target to match multiple pattern-specific
3380 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3381 variable.c, where they've always belonged.
3382 * rule.h: Move the prototypes and struct pattern_var as well.
3383 * variable.c (initialize_file_variables): Invoke
3384 lookup_pattern_var() in a loop, until no more matches are found.
3385 If a match is found, create a new variable set for the target's
3386 pattern variables. Then merge the contents of each matching
3387 pattern variable set into the target's pattern variable set.
3388 (lookup_pattern_var): Change this function to be usable
3389 in a loop. It takes a starting position: if NULL, start at the
3390 beginning; if non-NULL, start with the pattern variable after that
3391 position, and return the next matching pattern.
3392 (create_pattern_var): Create a unique instance of
3393 pattern-specific variables for every definition in the makefile.
3394 Don't combine the same pattern together. This allows us to
3395 process the variable handling properly even when the same pattern
3396 is used multiple times.
3397 (parse_variable_definition): New function: break out the parsing
3398 of a variable definition line from try_variable_definition.
3399 (try_variable_definition): Call parse_variable_definition to
3401 (print_variable_data_base): Print out pattern-specific variables.
3402 * variable.h (struct variable): Remember when a variable is
3403 conditional. Also remember its flavor.
3404 (struct pattern_var): Instead of keeping a variable set, we just
3405 keep a single variable for each pattern.
3406 * read.c (record_target_var): Each pattern variable contains only a
3407 single variable, not a set, so create it properly.
3408 * doc/make.texi (Pattern-specific): Document the new behavior.
3410 2003-04-17 Paul D. Smith <psmith@gnu.org>
3412 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3413 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3414 file/directory naming rules for VMS so I can't tell whether this
3417 2003-04-09 Paul D. Smith <psmith@gnu.org>
3419 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3420 DOS-style pathnames: backslash separators and drive specifiers.
3422 2003-03-28 Paul D. Smith <psmith@gnu.org>
3424 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3425 the intermediate flag on all targets. Fixes bug #2515.
3427 2003-03-24 Paul D. Smith <psmith@gnu.org>
3429 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3430 Upgrade to autoconf 2.57 and automake 1.7.3.
3432 * job.c: More OS/2 changes from Andreas Buening.
3434 * file.c (print_file): Fix variable initialization.
3437 * remake.c (notice_finished_file):
3439 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3440 some calls (like readdir()) return NULL in valid situations
3441 without resetting errno. Fixes bug #2846.
3443 2003-02-25 Paul D. Smith <psmith@gnu.org>
3445 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3447 * job.c (_is_unixy_shell) [OS/2]: New function.
3448 Set default shell to /bin/sh.
3449 (reap_children): Close the job_rfd pipe here since we don't use a
3451 (set_child_handler_action_flags): define this to empty on OS/2.
3452 (start_job_command): Close the jobserver pipe and use
3453 child_execute_job() instead of fork/exec.
3454 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3455 rather than exec'ing, then reconfigure stdin/stdout.
3456 (exec_command): Rewrite to use spawn instead of exec. Return the
3459 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3460 in DOS. Handle the TEMP environment variable as in DOS. Don't
3461 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3462 use -j in DOS mode. Use child_execute_job() instead of
3465 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3468 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3469 prototypes that return values.
3471 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3473 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3474 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3476 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3479 2003-02-24 Paul D. Smith <psmith@gnu.org>
3481 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3482 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3483 (child_execute_job) [VMS]: Handle error status properly.
3484 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3486 * function.c (func_shell): Use EINTRLOOP() while reading from the
3487 subshell pipe (Fixes bug #2502).
3488 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3490 * main.c (main): Ditto.
3492 2003-01-30 Paul D. Smith <psmith@gnu.org>
3494 * read.c (eval): eval() was not fully reentrant, because the
3495 collapsed buffer was static. Change it to be an automatic
3496 variable so that eval() can be invoked recursively.
3498 (eval): Apply patch # 1022: fix memory reference error on long
3499 target-specific variable lines.
3500 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3502 * function.c (check_numeric): Combine the is_numeric() function
3503 into this function, since it's only called from one place.
3504 Constify this function. Have it print the incorrect string in the
3505 error message. Fixes bug #2407.
3506 (strip_whitespace): Constify.
3507 (func_if): Constify.
3508 * expand.c (expand_argument): Constify.
3510 2003-01-29 Paul D. Smith <psmith@gnu.org>
3512 Fix bug # 2169, also reported by other people on various systems.
3514 * make.h: Some systems, such as Solaris and PTX, do not fully
3515 implement POSIX-compliant SA_RESTART functionality; important
3516 system calls like stat() and readdir() can still fail with EINTR
3517 even if SA_RESTART has been set on the signal handler. So,
3518 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3519 EINTR for system calls which return -1 or 0 (NULL), respectively,
3521 Also, remove the old atomic_stat()/atomic_readdir() and
3522 HAVE_BROKEN_RESTART handling.
3524 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3526 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3527 * remake.c (touch_file): Ditto.
3529 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3530 * read.c (construct_include_path): Ditto.
3531 * remake.c (name_mtime): Ditto.
3532 * vpath.c (selective_vpath_search): Ditto.
3533 * dir.c (find_directory): Ditto.
3534 (local_stat): Ditto.
3535 (find_directory): Use ENULLLOOP() to wrap opendir().
3536 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3538 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3539 atomic_readdir() handling.
3541 2003-01-22 Paul D. Smith <psmith@gnu.org>
3543 * function.c (func_call): Fix Bug #1744. If we're inside a
3544 recursive invocation of $(call ...), mask any of the outer
3545 invocation's arguments that aren't used by this one, so that this
3546 invocation doesn't "inherit" them accidentally.
3548 2002-12-05 Paul D. Smith <psmith@gnu.org>
3550 * function.c (subst_expand): Valery Khamenia reported a
3551 pathological performance hit when doing substitutions on very
3552 large values with lots of words: turns out we were invoking
3553 strlen() a ridiculous number of times. Instead of having each
3554 call to sindex() call strlen() again, keep track of how much of
3555 the text we've seen and pass the length to sindex().
3557 2002-11-19 Paul D. Smith <psmith@gnu.org>
3559 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3562 2002-11-16 Paul D. Smith <psmith@gnu.org>
3564 * NMakefile.template (OBJS): Add hash.c object file.
3565 * SMakefile.template (srcs): Ditto.
3566 * Makefile.ami (objs): Ditto.
3567 * build_w32.bat: Ditto.
3569 * Makefile.DOS.template: Remove extra dependencies.
3571 2002-10-25 Paul D. Smith <psmith@gnu.org>
3573 * expand.c (install_variable_buffer): New function. Install a new
3574 variable_buffer context and return the previous one.
3575 (restore_variable_buffer): New function. Free the current
3576 variable_buffer context and put a previously saved one back.
3577 * variable.h: Prototypes for {install,restore}_variable_buffer.
3578 * function.c (func_eval): Push a new variable_buffer context
3579 before we eval, then restore the old one when we're done.
3582 * read.c (install_conditionals): New function. Install a new
3583 conditional context and return the previous one.
3584 (restore_conditionals): New function. Free the current
3585 conditional context and put a previously saved one back.
3586 (eval): Use the {install,restore}_conditionals for "include"
3588 (eval_buffer): Use {install,restore}_conditionals to preserve the
3589 present conditional state before we evaluate the buffer.
3592 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3594 (Recursion): Add a variable index entry for CURDIR.
3596 * README.cvs: Update to appropriate versions.
3597 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3598 don't need to copy loadavg.c: automake is smart enough to create
3599 it for me. Still have a bug in automake related to ansi2knr tho.
3601 2002-10-14 Paul D. Smith <psmith@gnu.org>
3603 * remake.c (notice_finished_file): Only touch targets if they have
3604 at least one command (as per POSIX). Resolve Bug #1418.
3606 * *.c: Convert to using ANSI C-style function definitions.
3607 * Makefile.am: Enable the ansi2knr feature of automake.
3608 * configure.in: ditto.
3610 2002-10-13 Paul D. Smith <psmith@gnu.org>
3612 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3613 for automatic variable values like $^, etc. In the case of very
3614 large lists of prerequisites this causes problems. Instead reuse
3615 a static buffer (resizeable) for each variable.
3617 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3618 target-specific variable definitions. Check for it and set an
3620 (record_target_var): Set the export field to v_export if the
3621 "exported" flag is set.
3622 * doc/make.texi (Target-specific): Document the ability to use
3625 * doc/make.texi: Change the name of the section on automatic
3626 variables from "Automatic" to "Automatic Variables". Added text
3627 clarifying the scope of automatic variables.
3629 2002-10-04 Paul D. Smith <psmith@gnu.org>
3631 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3633 (record_files): Ditto.
3635 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3636 the search for the '=' to only within the enclosing parens.
3638 2002-10-03 Paul D. Smith <psmith@gnu.org>
3640 Version 3.80 released.
3642 * dir.c: Change hash functions to use K&R function definition style.
3643 * function.c: Ditto.
3645 * variable.c: Ditto.
3647 Update to automake 1.7.
3649 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3650 (pdf): Remove this target as automake now provides one.
3652 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3654 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3656 * makefile.com: Updates for GNU make 3.80.
3657 * makefile.vms: Ditto.
3659 2002-09-23 Paul D. Smith <psmith@gnu.org>
3661 * read.c (enum make_word_type): Remove w_comment.
3662 (get_next_mword): Don't treat comment characters as special; where
3663 this function is used we will never see a comment (it's stripped
3664 before we get here) and treating comments specially means that
3665 targets like "foo\#bar" aren't handled properly.
3667 2002-09-18 Paul D. Smith <psmith@gnu.org>
3669 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3671 * read.c (eval): Expansion of arguments to export/unexport was
3672 ignoring all arguments after the first one. Change the algorithm
3673 to expand the whole line once, then parse the results.
3675 2002-09-17 Paul D. Smith <psmith@gnu.org>
3677 Fix Bug #940 (plus another bug I found while looking at this):
3679 * read.c (record_target_var): enter_file() will add a new entry if
3680 it's a double-colon target: we don't want to do that in this
3681 situation. Invoke lookup_file() and only enter_file() if it does
3682 not already exist. If the file we get back is a double-colon then
3683 add this variable to the "root" double-colon target.
3685 * variable.c (initialize_file_variables): If this file is a
3686 double-colon target but is not the "root" target, then initialize
3687 the root and make the root's variable list the parent of our
3690 2002-09-13 Paul D. Smith <psmith@gnu.org>
3692 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3694 * hash.c (round_up_2): Get rid of a warning.
3696 2002-09-12 Paul D. Smith <psmith@gnu.org>
3698 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3699 so it doesn't complain about getloadavg.c.
3701 * commands.c (set_file_variables): Make sure we always alloca() at
3702 least 1 character for the value of $? (for '\0').
3704 2002-09-11 Paul D. Smith <psmith@gnu.org>
3706 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3707 macro to use RESULT instead of the incorrect _RESULT_.
3709 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3710 and atomic_readdir(). We need to #include dirent.h to get this to
3712 * misc.c (atomic_readdir): Fix typos.
3714 2002-09-10 Paul D. Smith <psmith@gnu.org>
3716 * read.c (eval): Expand variable lists given to export and
3717 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3718 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3720 * doc/make.texi (Variables/Recursion): Document this.
3721 (Conditional Syntax): And here.
3723 2002-09-09 Paul D. Smith <psmith@gnu.org>
3725 * configure.in: Check for memmove().
3727 2002-09-07 Paul D. Smith <psmith@gnu.org>
3729 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3730 Michael Sterrett <msterret@coat.com> reports that while it has
3731 SA_RESTART, it does not work properly.
3733 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3734 that invokes stat() and loops to do it again if it returns EINTR.
3735 (atomic_readdir): Ditto, with readdir().
3737 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3738 and readdir() to atomic_stat() and atomic_readdir().
3740 2002-09-04 Paul D. Smith <psmith@gnu.org>
3742 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3743 reports that GNU make sometimes doesn't recognize that targets can
3744 be made, when directories can be created as prerequisites. He
3745 reports that changing the order of predicates in the DEP->changed
3746 flag test so that lookup_file() is always performed, solves this
3749 2002-08-08 Paul D. Smith <psmith@gnu.org>
3751 * configure.in: Require a newer version of gettext.
3753 * misc.c (perror_with_name): Translate the format string (for
3754 right-to-left language support).
3755 (pfatal_with_name): Ditto.
3757 * main.c: Create a static array of strings to store the usage
3758 text. This is done to facilitate translations.
3759 (struct command_switch): Remove argdesc and description fields.
3760 (switches): Remove values for obsolete fields.
3761 (print_usage): Print each element of the usage array.
3763 * hash.c: Change function definitions to be K&R style.
3765 2002-08-02 Paul D. Smith <psmith@gnu.org>
3767 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3768 this one because it's too hard to get right. We'll look at it for
3770 * main.c (main): Don't create the .TARGETS variable.
3771 * variable.c (handle_special_var): Don't handle .TARGETS.
3773 2002-08-01 Paul D. Smith <psmith@gnu.org>
3775 * main.c (switches): Add a new option, -B (--always-make). If
3776 specified, make will rebuild all targets that it encounters even
3777 if they don't appear to be out of date.
3778 (always_make_flag): New flag.
3779 * make.h: Extern always_make_flag.
3780 * remake.c (update_file_1): Check always_make_flag; if it's set we
3781 will always rebuild any target we can, even if none of its
3782 prerequisites are newer.
3785 * doc/make.texi (Shell Function): Make it clear that make
3786 variables marked as "export" are not passed to instances of the
3789 Add new introspection variable .VARIABLES and .TARGETS.
3791 * variable.c (handle_special_var): New function. If the variable
3792 reference passed in is "special" (.VARIABLES or .TARGETS),
3793 calculate the new value if necessary. .VARIABLES is handled here:
3794 walk through the hash of defined variables and construct a value
3795 which is a list of the names. .TARGETS is handled by
3796 build_target_list().
3797 (lookup_variable): Invoke handle_special_var().
3798 * file.c (build_target_list): Walk through the hask of known files
3799 and construct a list of the names of all the ones marked as
3801 * main.c (main): Initialize them to empty (and as simple variables).
3802 * doc/make.texi (Special Variables): Document them.
3803 * NEWS: Mention them.
3805 * variable.h (struct variable): Add a new flag "exportable" which
3806 is true if the variable name is valid for export.
3807 * variable.c (define_variable_in_set): Set "exportable" when a new
3808 variable is defined.
3809 (target_environment): Use the "exportable" flag instead of
3810 re-checking the name here... an efficiency improvement.
3812 2002-07-31 Paul D. Smith <psmith@gnu.org>
3814 * config.h-vms.template: Updates to build on VMS. Thanks to
3815 Brian_Benning@aksteel.com for helping verify the build.
3816 * makefile.com: Build the new hash.c file.
3817 * hash.h: Use strcpmi(), not stricmp(), in the
3818 HAVE_CASE_INSENSITIVE_FS case.
3820 2002-07-30 Paul D. Smith <psmith@gnu.org>
3822 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3823 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3824 Reported by <Brian_Benning@aksteel.com>.
3826 2002-07-10 Paul D. Smith <psmith@gnu.org>
3828 * variable.c (pop_variable_scope): Remove variable made unused by
3829 new hash infrastructure.
3830 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3831 comparisons as well as name comparisons.
3832 * variable.h: Add a prototype for new hash_init_function_table().
3833 * file.c (lookup_file): Remove variables made unused by new hash
3835 * dir.c (directory_contents_hash_2): Missing return of hash value.
3836 (dir_contents_file_exists_p): Remove variables made unused by new
3837 hash infrastructure.
3840 Installed Greg McGary's integration of the hash functions from the
3841 GNU id-utils package:
3843 2002-07-10 Greg McGary <greg@mcgary.org>
3845 * scripts/functions/filter-out: Add literals to to the
3846 pattern space in order to add complexity, and trigger
3847 use of an internal hash table. Fix documentation strings.
3848 * scripts/targets/INTERMEDIATE: Reverse order of files
3849 passed to expected `rm' command.
3851 2002-07-10 Greg McGary <greg@mcgary.org>

3943 2002-07-10 Paul D. Smith <psmith@gnu.org>
3945 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3946 prerequisite list. A real SysV make will expand the entire
3947 prerequisites list _twice_: we don't do that as it's a big
3948 backward-compatibility problem. We only replace those specific
3951 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3952 references left in the list of prerequisites. Check for .POSIX as
3953 we record targets, so we can disable non-POSIX behavior while
3954 reading makefiles as well as running them.
3955 (eval): Check the prerequisite list to see if we have anything
3956 that looks like a SysV prerequisite variable reference.
3958 2002-07-09 Paul D. Smith <psmith@gnu.org>
3960 * doc/make.texi (Prerequisite Types): Add a new section describing
3961 order-only prerequisites.
3963 * read.c (uniquize_deps): If we have the same file as both a
3964 normal and order-only prereq, get rid of the order-only prereq,
3965 since the normal one supersedes it.
3967 2002-07-08 Paul D. Smith <psmith@gnu.org>
3969 * AUTHORS: Added Greg McGary to the AUTHORS file.
3970 * NEWS: Blurbed order-only prerequisites.
3971 * file.c (print_file): Show order-only deps properly when printing
3974 * maintMakefile: Add "update" targets for wget'ing the latest
3975 versions of various external files. Taken from Makefile.maint in
3978 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3979 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3981 2002-07-07 Paul D. Smith <psmith@gnu.org>
3983 * po/*.po: Remove. We'll use wget to retrieve them at release
3986 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3987 rather than a shell you get an exception. Make sure we look up
3988 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3990 * remake.c (notice_finished_file): Fix handling of -t flag.
3991 Patch provided by Henning Makholm <henning@makholm.net>.
3993 * implicit.c (pattern_search): Some systems apparently run short
3994 of stack space, and using alloca() in this function caused an
3995 overrun. I modified it to use xmalloc() on the two variables
3996 which seemed like they might get large. Fixes Bug #476.
3998 * main.c (print_version): Update copyright notice to conform with
4000 (print_usage): Update help output.
4002 * function.c (func_eval): Create a new make function, $(eval
4003 ...). Expand the arguments, put them into a buffer, then invoke
4004 eval_buffer() on the resulting string.
4005 (func_quote): Create a new function, $(quote VARNAME). Inserts
4006 the value of the variable VARNAME without expanding it any
4009 * read.c (struct ebuffer): Change the linebuffer structure to an
4010 "eval buffer", which can be either a file or a buffer.
4011 (eval_makefile): Move the code in the old read_makefile() which
4012 located a makefile into here: create a struct ebuffer with that
4013 information. Have it invoke the new function eval() with that
4015 (eval_buffer): Create a new function that creates a struct ebuffer
4016 that holds a string buffer instead of a file. Have it invoke
4017 eval() with that ebuffer.
4018 (eval): New function that contains the guts of the old
4019 read_makefile() function: this function parses makefiles. Obtains
4020 data to parse from the provided ebuffer. Some modifications to
4021 make the flow of the function cleaner and clearer. Still could
4022 use some work here...
4023 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
4024 contents of the define/endef variable from the ebuffer.
4025 (readstring): Read the next line from a string-style ebuffer.
4026 (readline): Read the next line from an ebuffer. If it's a string
4027 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
4030 * dep.h (eval_buffer): Prototype eval_buffer();
4032 * variable.c (do_variable_definition): Make sure that all
4033 non-target-specific variables are registered in the global set.
4034 If we're invoked from an $(eval ...) we might be inside a $(call
4035 ...) or other function which has pushed a variable scope; we still
4036 want to define our variables from evaluated makefile code in the
4039 2002-07-03 Greg McGary <greg@mcgary.org>
4041 * dep.h (struct dep) [ignore_mtime]: New member.
4042 [changed]: convert to a bitfield.
4043 * implicit.c (pattern_search): Zero ignore_mtime.
4044 * main.c (main, handle_non_switch_argument): Likewise.
4045 * rule.c (convert_suffix_rule): Likewise.
4046 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
4047 (read_makefile): Parse '|' in prerequisite list.
4048 (uniquize_deps): Consider ignore_mtime when comparing deps.
4049 * remake.c (update_file_1, check_dep): Don't force remake for
4050 dependencies that have d->ignore_mtime.
4051 * commands.c (FILE_LIST_SEPARATOR): New constant.
4052 (set_file_variables): Don't include a
4053 prerequisite in $+, $^ or $? if d->ignore_mtime.
4056 2002-06-18 Paul D. Smith <psmith@gnu.org>
4058 * make.texinfo: Updates for next revision. New date/rev/etc.
4059 Recreate all Info menus. Change license on the manual to the GNU
4060 Free Documentation License. A number of typos.
4061 (Variables Simplify): Don't use "-" before it's defined.
4062 (Automatic Prerequisites): Rewrite the target example to work
4063 properly if the compile fails. Remove incorrect comments about
4064 how "set -e" behaves.
4065 (Text Functions): Move the "word", "wordlist", "words", and
4066 "firstword" functions here, from "File Name Functions".
4067 * make-stds.texi: Update from latest GNU version.
4068 * fdl.texi: (created) Import the latest GNU version.
4070 2002-06-06 Paul D. Smith <psmith@gnu.org>
4072 * variable.c (do_variable_definition): New function: extract the
4073 part of try_variable_definition() that actually sets the value
4074 into a separate function.
4075 (try_variable_definition): Call do_variable_definition() after
4076 parsing the variable definition string.
4077 (define_variable_in_set): Make the name argument const.
4079 * variable.h (enum variable_flavor): Make public.
4080 (do_variable_definition): Create prototype.
4082 * read.c (read_all_makefiles): Create a new built-in variable,
4084 (read_makefile): Add each makefile read in to this variable value.
4086 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4088 * Makefile.DOS.template: Tweak according to changes in the
4089 distribution. Add back the dependencies of *.o files.
4091 * configh.dos.template: Synchronize with config.h.in.
4093 2002-05-09 Paul D. Smith <psmith@gnu.org>
4095 * file.c (file_timestamp_now): Use K&R function declaration.
4097 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4098 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4099 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4100 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4101 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4102 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4103 nlist.n_name is a pointer rather than an array.
4105 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4106 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4107 * configure.in: Use it instead of the old version.
4109 * main.c (main): Prefer setvbuf() to setlinebuf().
4111 2002-05-08 Paul D. Smith <psmith@gnu.org>
4113 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4114 (loadavg_LDADD): Ditto.
4116 2002-04-29 Paul D. Smith <psmith@gnu.org>
4118 * expand.c (recursively_expand_for_file): Rename
4119 recursively_expand() to recursively_expand_for_file() and provide
4120 an extra argument, struct file. If the argument is provided, set
4121 the variable scope to that of the file before expanding.
4122 * variable.h (recursively_expand): Make this a macro that invokes
4123 recursively_expand_for_file() with a NULL file pointer.
4124 * variable.c (target_environment): Call the renamed function and

4126 Fixes Debian bug #144306.
4128 2002-04-28 Paul D. Smith <psmith@gnu.org>
4130 Allow $(call ...) user-defined variables to be self-referencing
4131 without throwing an error. Allows implementation of transitive
4132 closures, among other possibly useful things.
4133 Requested by: Philip Guenther <guenther@sendmail.com>
4135 * variable.h (struct variable): Add a new field: exp_count, and
4136 new macros to hold its size and maximum value.
4137 (warn_undefined): Make this a macro.
4138 * variable.c (define_variable_in_set): Initialize it.
4139 * expand.c (recursively_expand): If we detect recursive expansion
4140 of a variable, check the exp_count field. If it's greater than 0
4141 allow the recursion and decrement the count.
4142 (warn_undefined): Remove this (now a macro in variable.h).
4143 * function.c (func_call): Before we expand the user-defined
4144 function, modify its exp_count field to contain the maximum
4145 number of recursive calls we'll allow. After the call, reset it
4148 2002-04-21 Paul D. Smith <psmith@gnu.org>
4150 Modified to use latest autoconf (2.53), automake (1.6.1), and
4151 gettext (0.11.1). We're using gettext's new "external" support,
4152 to avoid including libintl source with GNU make.
4154 * README.cvs: New file. Explain how to build GNU make from CVS.
4156 * configure.in: Modify checking for the system glob library.
4157 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4158 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4159 etc. will manage it correctly). Set an automake conditional
4160 USE_LOCAL_GLOB to decide whether to compile the glob library.
4162 * getloadavg.c (main): Include make.h in the "TEST" program to
4165 * Makefile.am: Remove special rules for loadavg. Replace them
4166 with Automake capabilities for building extra programs.
4168 * signame.c: This file does nothing if the system provide
4169 strsignal(). If not, it implements strsignal(). If the system
4170 doesn't define sys_siglist, then we make our own; otherwise we use
4172 * signame.h: Removed.
4174 * main.c (main): No need to invoke signame_init(). Update copyright.
4176 * ABOUT-NLS: Removed.
4177 * gettext.c: Removed.
4178 * gettext.h: Get a simplified copy from the gettext package.
4180 * i18n/*.po: Moved to po/.
4183 * config/*: Created. Contains package configuration helper files.
4184 * config.guess, config.sub: Moved to config directory.
4186 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4187 Rework to use new-style autoconf features. Use the "external"
4188 mode for gettext. Make the build.sh config file conditional on
4189 whether build.sh.in exists, to avoid autoconf errors.
4190 * acinclude.m4: Removed almost all macros as being obsolete.
4191 Rewrote remaining macros to use AC_DEFINE.
4192 * acconfig.h: Removed.
4194 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4195 conditional to handle customs support. Remove special handling
4198 2002-04-20 Paul D. Smith <psmith@gnu.org>
4200 * function.c (func_call): Don't mark the argument variables $1,
4201 etc. as recursive. They've already been fully expanded so
4202 there's no need to do it again, and doing so strips escaped $'s.
4203 Reported by Sebastian Glita <glseba@yahoo.com>.
4205 * remake.c (notice_finished_file): Walk through double-colon
4206 entries via the prev field, not the next field!
4207 Reported by Greg McGary <greg@mcgary.org>.
4209 * main.c (main): If the user specifies -q and asks for a specific
4210 target which is a makefile, we got an assert. In that case it
4211 turns out we should continue normally instead.
4213 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4215 * i18n/he.po: Installed a new translation.
4217 2002-01-07 Paul D. Smith <psmith@gnu.org>
4219 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4221 2001-12-04 Paul D. Smith <psmith@gnu.org>
4223 * i18n/ja.po: Installed an updated translation.
4225 2001-09-06 Paul Eggert <eggert@twinsun.com>
4227 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4228 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4230 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4232 (main): Get rid of any avoidable limit on stack size.
4234 2001-09-04 Paul D. Smith <psmith@gnu.org>
4236 * i18n/da.po: Installed an updated translation.
4238 2001-08-03 Paul D. Smith <psmith@gnu.org>
4240 * i18n/fr.po: Installed an updated translation.
4241 Resolves Debian bug #106720.
4243 2001-06-13 Paul D. Smith <psmith@gnu.org>
4245 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4248 2001-06-11 Paul D. Smith <psmith@gnu.org>
4250 * i18n/ko.po: Installed a new translation.
4252 2001-05-06 Paul D. Smith <psmith@gnu.org>
4254 Modify the EINTR handling.
4256 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4257 the way in which we manage the file descriptor/signal handler race
4258 trap to be more efficient.
4260 2001-05-06 Paul Eggert <eggert@twinsun.com>
4262 Restart almost all system calls that are interrupted, instead
4263 of worrying about EINTR. The lone exception is the read() for
4266 * configure.in (HAVE_SA_RESTART): New macro.
4267 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4268 * main.c (main): Use SA_RESTART instead of the old,
4269 nonstandard SA_INTERRUPT.
4271 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4272 * main.c (bsd_signal): New function or macro,
4273 if the implementation doesn't supply it.
4274 (The bsd_signal function will be in POSIX 1003.1-200x.)
4275 (HANDLESIG): Remove.
4276 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4278 * make.h (EINTR_SET): Remove.
4279 (SA_RESTART): New macro.
4281 * arscan.c (ar_member_touch): Don't worry about EINTR.
4282 * function.c (func_shell): Likewise.
4283 * job.c (reap_children, free_child, new_job): Likewise.
4284 * main.c (main): Likewise.
4285 * remake.c (touch_file, name_mtime): Likewise.
4287 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4288 if fstat failed with errno!=EINTR, the error was ignored.
4290 * job.c (set_child_handler_action_flags): New function.
4291 (new_job): Use it to temporarily clear the SIGCHLD action flags
4292 while reading the token.
4294 2001-05-02 Paul D. Smith <psmith@gnu.org>
4296 * job.c (start_job_command): Don't add define/endef per-line flags
4297 to the top-level flags setting.
4299 2001-04-03 Paul D. Smith <psmith@gnu.org>
4301 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4302 bit on error, so check for odd return values, not non-0 return
4304 (VMS_get_member_info): Calculate the timezone differences correctly.
4305 Reported by John Fowler <jfowler@nyx.net>.
4308 2001-03-14 Paul D. Smith <psmith@gnu.org>
4310 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4311 value before invoking define_variable().
4312 Reported by John Fowler <jfowler@nyx.net>.
4314 2001-02-07 Paul D. Smith <psmith@gnu.org>
4316 * read.c (record_target_var): If we reset the variable due to a
4317 command-line variable setting overriding it, turn off the "append"
4320 2001-01-17 Paul D. Smith <psmith@gnu.org>
4322 * variable.c (lookup_variable) [VMS]: When getting values from the
4323 environment, allocate enough space for the _value_ plus escapes,
4324 not enough space for the name plus escapes :-/.
4325 Reported by John Fowler <jfowler@nyx.net>.
4327 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4328 warnings that make generates, so it doesn't look like an error.
4329 Reported by Karl Berry <karl@gnu.org>.
4332 Fix for PR/2020: Rework appended target-specific variables. I'm
4333 fairly confident this algorithm is finally correct.
4335 * expand.c (allocated_variable_append): Rewrite. Instead of
4336 expanding each appended variable then adding all the expanded
4337 strings together, we append all the unexpanded values going up
4338 through the variable set contexts, then expand the final result.
4339 This behaves just like non-target-specific appended variable
4340 values, while the old way didn't in various corner cases.
4341 (variable_append): New function: recursively append the unexpanded
4342 value of a variable, walking from the outermost variable scope to
4344 * variable.c (lookup_variable): Remove the code that looked up the
4345 variable set list if the found variable was "append". We don't
4347 (lookup_variable_in_set): Make this non-static so we can use it
4349 (try_variable_definition): Use lookup_variable_in_set() rather
4350 than faking out current_variable_set_list by hand (cleanup).
4351 * variable.h: Add a prototype for the now non-static
4352 lookup_variable_in_set().
4354 2000-11-17 Paul D. Smith <psmith@gnu.org>
4356 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4357 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4358 before throwing a fit.
4360 2000-11-17 Paul D. Smith <psmith@gnu.org>
4362 * read.c (readline): CRLF calculations had a hole, if you hit the
4363 buffer grow scenario just right. Reworked the algorithm to avoid
4364 the need for len or lastlen at all. Problem description with
4365 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4367 2000-10-24 Paul D. Smith <psmith@gnu.org>
4369 * gettext.c (SWAP): Declare this with the prototype, otherwise
4370 some systems don't work (non-32-bit? Reported for Cray T3E).
4371 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4373 2000-10-05 Paul D. Smith <psmith@gnu.org>
4375 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4376 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4378 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4380 2000-09-22 Paul D. Smith <psmith@gnu.org>
4382 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4383 parts of the real gettext.h here, and we expect to really include
4384 the real gettext.h later. If we keep this #define, it's ignored.
4386 2000-09-21 Paul D. Smith <psmith@gnu.org>
4388 * main.c (log_working_directory): Rework the text to use complete
4389 sentences, to make life simpler for the translators.
4391 2000-08-29 Paul D. Smith <psmith@gnu.org>
4393 * file.c (remove_intermediates): Print a debug message before we
4394 remove intermediate files, so the user (if she uses -d) knows
4397 2000-08-21 Paul D. Smith <psmith@gnu.org>
4399 * variable.c (try_variable_definition): Change how we handle
4400 target-specific append variable defns: instead of just setting the
4401 value, expand it as an append _but_ only within the current
4402 target's context. Otherwise we lose all but the last value if the
4403 variable is appended more than once within the current target
4404 context. Fixes PR/1831.
4406 2000-08-16 Paul D. Smith <psmith@gnu.org>
4408 * function.c (func_shell): Nul-terminate the buffer before
4409 printing an exec error message (just in case it's not!).
4410 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4412 2000-07-25 Paul D. Smith <psmith@gnu.org>
4414 * job.c (construct_command_argv_internal): Add "~" to the list of
4415 sh_chars[] which disallow optimizing out the shell call.
4417 2000-07-23 Paul Eggert <eggert@twinsun.com>
4419 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4420 supersedes --disable-nsec-timestamps.
4421 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4422 * README: Remove --disable-nsec-timestamps.
4424 * filedef.h (struct file.low_resolution_time): New member.
4425 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4426 * remake.c (update_file_1):
4427 Avoid spurious rebuilds due to low resolution time stamps,
4428 generalizing the earlier code that applied only to archive members.
4429 (f_mtime): Archive members always have low resolution time stamps.
4431 * configure.in: Remove --disable-nsec-timestamps, as this has
4432 been superseded by .LOW_RESOLUTION_TIME.
4434 2000-07-23 Paul Eggert <eggert@twinsun.com>
4436 * configure.in (enable_nsec_timestamps): Renamed from
4437 make_cv_nsec_timestamps, since enable/disable options
4438 shouldn't be cached.
4440 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4441 and Paul Eggert <eggert@twinsun.com>
4443 * file.c (file_timestamp_now):
4444 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4445 so that clock_gettime is not linked unless needed.
4447 * filedef.h (FILE_TIMESTAMP_HI_RES):
4448 Remove definition; "configure" now does this.
4450 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4451 to before high resolution file timestamp check,
4452 since that check now uses uintmax_t.
4453 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4454 high resolution file timestamps.
4455 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4456 so that we don't link in clock_gettime unnecessarily.
4458 2000-07-17 Paul D. Smith <psmith@gnu.org>
4460 * i18n/ja.po: New version of the translation file.
4462 2000-07-07 Paul D. Smith <psmith@gnu.org>
4464 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4465 the offset calculation.
4466 (name_mtime): Replace EINTR test with EINTR_SET macro.
4468 2000-07-07 Paul Eggert <eggert@twinsun.com>
4472 * remake.c (update_file_1):
4473 Avoid spurious rebuilds of archive members due to their
4474 timestamp resolution being only one second.
4475 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4476 the clock's resolution being lower than file timestamps'.
4477 When warning about future timestamps, report only the discrepancy,
4478 not the absolute value of the timestamp and the current time.
4480 * file.c (file_timestamp_now): New arg RESOLUTION.
4481 * filedef.h (file_timestamp_now): Likewise.
4482 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4484 2000-07-05 Paul D. Smith <psmith@gnu.org>
4486 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4487 to listp. Fixes PR/1793.
4489 2000-06-26 Paul Eggert <eggert@twinsun.com>
4491 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4493 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4495 * remake.c (f_mtime): Remove unused var memtime.
4497 2000-06-25 Martin Buchholz <martin@xemacs.org>
4499 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4500 Ran spell-check on make.texinfo.
4502 2000-06-23 Paul D. Smith <psmith@gnu.org>
4504 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4505 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4506 * make.h: Define these macros.
4508 * Version 3.79.1 released.
4510 * configure.in: Add a new option, --disable-nsec-timestamps, to
4511 avoid using sub-second timestamps on systems that support it. It
4512 can lead to problems, e.g. if your makefile relies on "cp -p".
4513 * README.template: Document the issue with "cp -p".
4515 * config.guess, config.sub: Updated.
