666 * read.c (parse_file_seq): All archive groups must end with ')' as
667 the LAST character in a word. If there is no word ending in ')'

670 2010-07-01 Paul Smith <psmith@gnu.org>
672 * main.c (main): Append optional features using separate calls.

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

734 lowest directory index.
736 * implicit.c (pattern_search): Pass NULL for the index arguments in
737 the VPATH_SEARCH call.
739 * doc/make.texi (Directory Search for Link Libraries): Describe the

829 2009-10-03 Paul Smith <psmith@gnu.org>
831 * make.h: Include <alloca.h> even on systems where __GNUC__ is

891 double-colons have a different meaning. Savannah bug #27497.
893 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
895 * configh.dos.template: Remove unconditional definition of
896 SYS_SIGLIST_DECLARED.
897 Include <sys/version.h> because ports of GCC 4.3.0 and later no
898 longer include it, so macros like __DJGPP_MINOR__ are no longer
899 defined automatically.
901 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
902 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
903 instead of using the hardcoded ones.
904 (SUBDIRS): doc subdir added.
905 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
906 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
907 create html formated docs. texi2html may not be ported to DOS.
908 (make.info, make.dvi, make.ps, make.html): Make targets depend on
910 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
911 -I switch to look in ./ instead of ./doc.

913 (make_1.html): Removed.
914 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
915 (all-recursive): Allow for more than one subdir in the build
917 (mostlyclean-recursive, clean-recursive, distclean-recursive)
918 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
919 (tags-recursive): Allow for more than one subdir in the build
921 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
922 targets. Enter into doc/ to produce the targets.
923 (all-am): $(INFO_DEPS) replaced by info.
925 2009-09-26 Paul Smith <psmith@gnu.org>
927 * read.c (record_files): Use free_ns() to free struct nameseq.
930 * rule.c (freerule): Use free_dep_chain().
932 * read.c (record_files): Free FILENAMES chain for implicit rules.
933 (eval): Static pattern targets go into the string cache.
935 * function.c (string_glob): Free NAME in the nameseq chain.
937 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
939 * implicit.c (pattern_search): Terminate early if we haven't
940 found any rules to try (performance improvement).
942 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
944 * implicit.c (pattern_search): Merge three parallel arrays,
945 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
946 of struct TRYRULE. In the old version the latter two arrays
947 had insufficient length.
949 2009-09-24 Paul Smith <psmith@gnu.org>
951 * implicit.c (pattern_search): Add back support for order-only
952 prerequisites for secondary expansion implicit rules, that were
953 accidentally dropped. If we find a "|", enable order-only mode
954 and set IGNORE_MTIME on all deps that are seen afterward.
955 (pattern_search): Fix memory leaks: for intermediate files where
956 we've already set the file variable and pattern variable sets, be
957 sure to either save or free them as appropriate.
959 2009-09-23 Paul Smith <psmith@gnu.org>
961 Rework the way secondary expansion is stored, for efficiency.
962 This changes secondary expansion so that ONLY WHEN we know we have
963 a possibility of needing secondary expansion, do we defer the
964 secondary expansion. This means more parsing the deps but we use
965 a lot less memory (due to the strcache). Also, this fixes
968 * read.c (eval): Don't parse the dep string here anymore.
969 (record_files): Take the dep argument as an unparsed string. If
970 secondary expansion is enabled AND the prereq string has a '$' in
971 it, then set NEED_2ND_EXPANSION and keep the entire string.
972 Otherwise, parse the dep string here to construct the dep list
973 with the names in the strcache.
975 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
976 duplicate the name string (others are in the strcache).
978 * implicit.c: Remove struct idep and free_idep_chain(): unused.
979 (struct patdeps): New structure to store prereq information.
980 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
981 which prerequisites need expansion, and expand only those.
983 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
984 and enter_prereqs(). split_prereqs() takes a fully-expanded string
985 and splits it into a DEP list, handling order-only prereqs.
986 (enter_prereqs): This function enters a list of DEPs into the file
987 database. If there's a stem defined, expand any pattern chars.
988 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
989 set. Use the above functions.
990 (snap_deps): Only perform second expansion on prereqs that need it,
991 as defined by the NEED_2ND_EXPANSION flag.
992 (print_prereqs): New function to print the prereqs
993 (print_file): Call print_prereqs() rather than print inline.
995 * hash.h (STRING_COMPARE): Take advantage of strcache() by
997 (STRING_N_COMPARE): Ditto.
998 (ISTRING_COMPARE): Ditto.
1000 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
1001 (parse_file_seq): Return void*
1002 * read.c (parse_file_seq): Return void*.
1003 (eval): Invoke macroized version of parse_file_seq()
1004 * default.c (set_default_suffixes): Ditto.
1005 * file.c (split_prereqs): Ditto.
1006 * function.c (string_glob): Ditto.
1007 * main.c (main): Ditto.
1008 * rule.c (install_pattern_rule): Ditto.
1010 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
1012 2009-09-16 Paul Smith <psmith@gnu.org>
1014 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
1016 * dep.h: Create alloc_dep() / free_dep() macros.
1018 * implicit.c (pattern_search): Take advantage of the new
1019 parse_file_seq() to add the directory prefix to each prereq.
1021 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
1022 all. Avoid reversing chains. Support adding prefixes.
1023 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
1024 cached/non-cached results.
1025 (eval): Remove multi_glob() & invoke new parse_file_seq().
1026 * rule.c (install_pattern_rule): Ditto.
1027 * main.c (main): Ditto.
1028 * implicit.c (pattern_search): Ditto.
1029 * function.c (string_glob): Ditto.
1030 * file.c (parse_prereqs): Ditto.
1031 * default.c (set_default_suffixes): Ditto.
1033 * variable.c (parse_variable_definition): Don't run off the end of
1034 the string if it ends in whitespace (found with valgrind).
1036 * commands.c (set_file_variables): Keep space for all targets in
1037 $? if -B is given (found with valgrind).
1039 2009-09-15 Paul Smith <psmith@gnu.org>
1041 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
1042 (xcalloc): Add new function.
1043 * make.h: New declarations.
1045 * ar.c (ar_glob_match): New calling method for concat().
1046 * main.c (main): Ditto.

1048 * read.c (eval_makefile): Ditto.
1049 (tilde_expand): Ditto.
1050 (parse_file_seq): Ditto.
1051 * variable.c (target_environment): Ditto.
1052 (sync_Path_environment): Ditto.
1054 * ar.c (ar_glob_match): Use xcalloc().
1055 * dir.c (file_impossible): Ditto.
1056 * file.c (enter_file): Ditto.
1057 * job.c (new_job): Ditto.
1058 * read.c (parse_file_seq): Ditto.
1059 * vmsfunctions.c (opendir): Ditto.
1061 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
1063 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
1064 inside the loop that looks up environment for PATH.

1069 sync_Path_environment.
1071 2009-08-02 Paul Smith <psmith@gnu.org>
1073 * remake.c (notice_finished_file): Ensure file->cmds is not null
1074 before looping through them. Fixes Savannah bug #21824.
1076 * doc/make.texi (Wildcard Examples): Clarify when objects is
1077 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1078 (Include): Clarify the behavior of -include.
1079 Fixes Savannah bug #18963.
1081 2009-08-01 Paul Smith <psmith@gnu.org>
1083 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1084 etc. come on the command line. Fixes Savannah bug #27093.
1086 * expand.c (expand_argument): If the argument is large enough use
1087 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1089 * variable.c (do_variable_definition): Avoid using alloca() to
1090 hold values, which can be large. Fixes Savannah bug #23960.
1092 * job.c (new_job): Use memmove() instead of strcpy() since both
1093 pointers are in the same memory block. Fixes Savannah bug #27148.
1094 Patch by Petr Machata.
1096 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1098 * job.c (construct_command_argv_internal): Add "ulimit" and
1099 "unset" to the sh_cmds for Unixy shells.
1101 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1103 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1104 that set make_cv_sys_gnu_glob, so they are also correctly set
1105 when the cache has been populated before.
1107 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1109 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1110 exist, as realpath(3) does where it's supported.
1112 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1114 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1115 (abspath): Support systems that define HAVE_DOS_PATHS (have
1116 drive letters in their file names). Use IS_PATHSEP instead of a
1117 literal '/' comparison. Fixes Savannah bug #26886.
1119 2009-06-14 Paul Smith <psmith@gnu.org>
1121 * remake.c (update_file_1): Remember the original file we marked
1122 as updating, so we can clear that flag again. If we find a target
1123 via vpath, FILE might change.
1124 (check_dep): Ditto. Fixes Savannah bug #13529.
1125 Patch by Reid Madsen <reid.madsen@tek.com>.
1127 2009-06-13 Paul Smith <psmith@gnu.org>
1129 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1130 included by MAKEFILES cannot give default goals.
1131 * read.c (eval): If set_default is not set, pass the no-default-goal
1132 value when we read included makefiles. Fixes Savannah bug #13401.
1134 * ar.c (ar_name): Ensure that targets with empty parens aren't
1135 considered archive member references: archive members must have a
1136 non-empty "member" string. Fixes Savannah bug #18435.
1138 * function.c (string_glob): Rely on multi_glob() to determine
1139 whether files exist or not. Remove call to file_exists_p() which
1140 is not always correct. Fixes Savannah bug #21231.
1141 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1142 then only files that really exist will be returned.
1143 * dep.h: Add new argument to multi_glob().
1144 * rule.c (install_pattern_rule): Ditto.
1145 * read.c (eval): Ditto.
1146 * main.c (main): Ditto.
1147 * implicit.c (pattern_search): Ditto.
1148 * file.c (parse_prereqs): Ditto.
1149 * default.c (set_default_suffixes): Ditto.
1151 2009-06-09 Paul Smith <psmith@gnu.org>
1153 * commands.c (set_file_variables): If always_make_flag is set,
1154 always add the prereq to $?. Fixes Savannah bug #17825.
1156 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1157 to rebuild the deps of all the also_make targets for that file.
1158 Fixes Savannah bug #19108.
1160 * implicit.c (pattern_search): Undo test for is_target, added by
1161 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1162 Rule Search Algorithm". Fixes Savannah bug #17752.
1164 * main.c (clean_jobserver): Clear the jobserver_fds options and
1165 set job_slots to the default when we clean up.
1166 (define_makeflags): Return the new MAKEFLAGS value.
1167 (main): Reset MAKEFLAGS in the environment when we re-exec.
1168 Fixes Savannah bug #18124.
1170 2009-06-08 Paul Smith <psmith@gnu.org>
1172 * read.c (eval): Collapse continuations post-semicolon on target-
1173 specific variables. Fixes Savannah bug #17521.
1175 2009-06-07 Paul Smith <psmith@gnu.org>
1177 * job.c (reap_children): For older systems without waitpid() (are
1178 there any of these left?) run wait(2) inside EINTRLOOP to handle
1179 EINTR errors. Fixes Savannah bug #16401.
1181 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1183 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1185 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1186 not the end, to catch second expansion $(eval ...) defining new
1187 target/prereq relationships during snap_deps.
1188 Fixes Savannah bug #24622.
1190 * read.c (record_files): The second-expansion "f->updating" hack
1191 was not completely correct: if assumed that the target with
1192 commands always had prerequisites; if one didn't then the ordering
1193 was messed up. Fixed for now to use f->updating to decide whether
1194 to preserve the last element in the deps list... but this whole
1195 area of constructing and reversing the deps list is too confusing
1196 and needs to be reworked. Fixes Savannah bug #21198.
1198 2009-06-06 Paul Smith <psmith@gnu.org>
1200 * hash.c (hash_insert): Remove useless test for NULL.
1201 Fixes Savannah bug #21823.
1203 * make.h: Move SET_STACK_SIZE determination to make.h.
1204 * main.c (main): New global variable, STACK_LIMIT, holds the
1205 original stack limit when make was started.
1206 * job.c (start_job_command): Reset the stack limit, if we changed it.
1207 Fixes Savannah bug #22010.
1209 * remake.c (check_dep): Only set the target's state to not-started
1210 if it's not already running. Found this while testing -j10 builds
1211 of glibc: various targets were being rebuilt multiple times.
1212 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1215 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1216 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1219 2009-06-04 Paul Smith <psmith@gnu.org>
1221 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1223 * maintMakefile: Modify access of config and gnulib Savannah
1224 modules to use GIT instead of CVS.
1226 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1227 Fixes Savannah bug #24655.
1229 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1230 this can happen during some invocations of $(eval ...) for example.
1231 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1233 2009-06-02 Paul Smith <psmith@gnu.org>
1235 * configure.in: Check for fileno()
1236 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1237 for the makefile file so invocations of $(shell ...) don't inherit it.
1238 Fixes Savannah bug #24277.
1240 2009-06-01 Paul Smith <psmith@gnu.org>
1242 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1243 expansion was handled incorrectly. Rework the default goal
1244 handling to save the variable only. Remove default_goal_file and
1246 * read.c (eval): Check default_goal_var, not default_goal_name.
1247 * read.c (record_target_var): Don't check default_goal_file here.
1249 2009-05-31 Paul Smith <psmith@gnu.org>
1251 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1252 it, and if the multi_glob() returns nothing (say it expanded to
1253 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1255 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1256 $(and ..) to the reference. Fixes Savannah bug #25694.
1258 * make.1: Be clear that some recipes will be executed even with -n.
1259 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1261 * doc/make.texi (Override Directive): Make more clear how
1262 overrides and appends interact.
1263 Elucidates part of Savannah bug #26207.
1265 * read.c (record_target_var): Don't reset the origin on
1266 target-specific variables; try_variable_definition() will handle
1267 this correctly. Fixes Savannah bug #26207.
1269 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1270 Fixes Savannah bug #25712.
1272 * implicit.c (pattern_search): Keep a pointer to the beginning of
1273 the filename and save that instead of the constructed pointer.
1274 Fixes Savannah bug #26593.
1275 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1277 2009-05-30 Paul Smith <psmith@gnu.org>
1279 * doc/make.texi (Multi-Line): Add a description of the new abilities
1280 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1281 "command sequence" vs. "recipe" syntax.
1282 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1283 after a define, to create variables with those flavors.
1285 2009-05-25 Paul Smith <psmith@gnu.org>
1287 Reworked the parser for variable assignments to allow multiple
1288 modifiers, and in any order. Also allows variable and
1289 prerequisites to be modifier names ('export', 'private', etc.)
1291 * NEWS: Add notes about user-visible changes.
1293 * read.c (struct vmodifiers): Remember what modifiers were seen.
1294 (parse_var_assignment): New function to parse variable assignments.
1295 (eval): Call the new function. Handle variable assignments earlier.
1297 * variable.c (parse_variable_definition): Only parse; don't create var.
1298 (assign_variable_definition): Call parse, then create the var.
1300 2009-05-24 Paul Smith <psmith@gnu.org>
1302 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1303 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1305 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1307 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1308 Fixes Savannah bug #25412.
1310 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1311 prototype for xmalloc.
1312 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1313 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1314 Loop over an array of extensions, instead of duplicating the same
1315 code inline. Use SearchPath followed by CreateFile, instead of
1316 the obsolete OpenFile. Fixes Savannah bug #17277.
1317 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1318 to `find_file'. Fixes Savannah bug #25662.
1320 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1322 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1323 Fixes Savannah bug #20495.
1325 2009-02-28 Ralf Wildenhues <address@hidden>
1327 * doc/make.texi (Instead of Execution): Document interaction of
1328 -t with phony targets.
1330 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1332 Introduce a new keyword "private" which applies to target-specific
1333 variables and prevents their values from being inherited.
1335 * variable.h (struct variable): Add private_var flag to each variable.
1336 Add a flag to specify which list entry switches to the parent target.
1337 * variable.c (define_variable_in_set): Initialize private_var flag.
1338 (lookup_variable): Skip private variables in parent contexts.

1350 * make.h: Rename savestring to xstrndup.
1351 * commands.c (chop_commands): Ditto.
1352 * function.c (func_foreach): Ditto.
1353 * read.c (eval, record_files): Ditto.
1354 * variable.c (define_variable_in_set): Ditto.
1356 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1358 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1361 * w32/subproc/build.bat (GCCBuild): Likewise.
1363 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1365 * job.c (construct_command_argv_internal): Avoid extra backslash
1366 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1369 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1371 * README.W32.template: Remove obsolete text about non-support for
1372 -jN without Unixy shell. Remove obsolete text about not supplying
1373 Visual Studio project files (we do supply them). Modify text to
1374 prefer GCC builds to MSC builds.
1376 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1378 * doc/make.texi (Empty Targets): Fix typo.

1393 `value' field is NULL.
1395 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1397 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1399 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1400 (TEXINFOS): Value changed to `doc/make.texi'.
1401 (.SUFFIXES): Use .texi instead of .texinfo.
1402 (make.info, make.dvi): Depend on doc/make.texi.
1403 (.texi.info): New target, instead of ".texinfo.info". Change -I
1404 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1405 (.texi): New target, instead of ".texinfo". Change -I switch to
1406 $(MAKEINFO) to look in doc/. Use --no-split.
1407 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1408 switch to $(MAKEINFO) to look in doc/.
1409 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1410 "*.i[0-9][0-9]" (due to --no-split above).
1411 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1412 (html, make_1.html): New targets.
1413 (.PHONY): Add "html".

1419 HAVE_DECL_SYS_SIGLIST.
1421 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1422 build does not use child_execute_job.
1424 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1425 export the SHELL environment variable to the child.
1427 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1429 * config.h.W32: Include sys/types.h.
1430 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1432 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH

1446 * remake.c (f_mtime): Print time difference values between 100 and
1447 ULONG_MAX in fixed-point notation rather than in exponention notation.
1449 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1451 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1452 a more complex value than a simple shell: if it's not a default
1453 shell now then expand it and see if is a default shell then.
1455 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1457 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1458 pathnames, with const strings.
1459 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1460 from the template (used for building from CVS, not a dist).
1462 2007-10-10 Paul Smith <psmith@gnu.org>
1464 * make.h: Add a prototype for w32_kill() (change suggested by
1465 Yongwei Wu <wuyongwei@gmail.com>).
1467 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1469 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1470 directories in Path.
1472 2007-09-12 Paul Smith <psmith@gnu.org>

1475 Provided by Diego Biurrun <diego@biurrun.de>
1476 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1477 Provided by Diego Biurrun <diego@biurrun.de>
1479 2007-09-11 Paul Smith <psmith@gnu.org>
1481 * doc/make.texi (Special Variables): Moved this into the "How to
1482 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1483 (MAKEFILE_LIST) No longer a section; this was added into the
1484 "Special Variables" section.
1485 (Rule Introduction): Reference .RECIPEPREFIX.
1486 (Simple Makefile): Ditto.
1487 (Rule Syntax): Ditto.
1488 (Command Syntax): Ditto.
1489 (Error Messages): Ditto.
1491 2007-09-10 Paul Smith <psmith@gnu.org>
1493 * commands.c (print_commands): Don't print an extra line in the
1494 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1496 * read.c (construct_include_path): Add the full string to the cache; we
1497 were chopping the last char.
1499 * NEWS: Announce the .RECIPEPREFIX special variable.
1500 * variable.c (lookup_special_var): Rename from handle_special_var().
1501 (lookup_variable): Call the new name.
1502 (set_special_var): New function: handle setting of special variables.
1503 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1504 (do_variable_definition): Call it.
1505 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1506 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1507 * main.c (main): Create the .RECIPEPREFIX special variable.
1508 * read.c (eval): Remove the cmd_prefix characters from the command
1509 scripts here, so they're not stored in the commands array at all,
1510 rather than waiting and stripping them out during command construction.
1511 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1513 2007-08-15 Paul Smith <psmith@gnu.org>
1515 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1516 file has had the section info removed, so add some to make.texi
1517 before we include it.
1519 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1521 * remake.c (check_dep): Reset the target state for intermediate
1522 files. They might have been considered before but not updated
1523 then (order-only for example) but they will be this time.
1524 Fixes Savannah bug #'s 3330 and 15919.
1526 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1528 Fix Savannah bug #20549:
1529 * function.c (func_shell): Call construct_command_argv with zero
1531 * job.c (construct_command_argv_internal): New argument FLAGS; all
1533 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1535 * job.h (construct_command_argv_internal): Update prototype.
1537 2007-07-13 Paul Smith <psmith@gnu.org>
1539 * file.c (expand_deps): Use variable_buffer as the start of the
1540 buffer, not the original pointer (in case it was reallocated).
1541 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1542 Fixes Savannah bug #20452.
1544 2007-07-04 Paul Smith <psmith@gnu.org>
1546 * (ALL FILES): Update to GPLv3.
1547 * (ALL FILES): Update copyright for 2007.

1551 2007-06-29 Thiemo Seufer <ths@mips.com>
1553 * maintMakefile: Update Translation Project location.
1555 2007-06-13 Paul Smith <psmith@gnu.org>
1557 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1558 "Expansion of a deferred"
1559 Fixes Savannah bug #20018.

1562 reading_file rather than setting it to 0 at the end.
1563 Fixes Savannah bug #20033.
1565 2007-05-11 Paul Smith <psmith@gnu.org>
1567 * job.c (new_job): Add debug info to specify where make found the
1568 command script it is running to build a target.
1569 Fixes Savannah bug #18617.
1571 * default.c (default_suffixes,default_suffix_rules,default_variables):
1572 Add support for Objective C. Fixes Savannah bug #16389.

1579 Dave Korn <dave.korn@artimi.com>
1581 2007-05-08 Paul Smith <psmith@gnu.org>
1583 Fix Savannah bug #19656:
1585 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1587 * make.h: Change all case-insensitive string compares to use
1588 strcasecmp() (from POSIX). If we don't have that but do have one
1589 of the others, define strcasecmp to be one of those instead. If
1590 we don't have any, declare a prototype for our own version.
1592 * misc.c (strcasecmp): Use this if we can't find any native
1593 case-insensitive string comparison function.
1594 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1595 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1597 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1598 strcasecmp() instead of stricmp().
1599 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1600 instead of strcmpi().
1601 * acinclude.m4: Remove the strcasecmp() check from here.
1603 2007-03-21 Paul Smith <psmith@gnu.org>
1605 * configure.in: Don't turn on case-insensitive file system support
1606 if --disable-... is given. Fixes Savannah bug #19348.
1608 2007-03-19 Paul Smith <psmith@gnu.org>
1610 * ALL: Use the strcache for all file name strings, or other
1611 strings which we will never free. The goal is to save memory by
1612 avoiding duplicate copies of strings. However, at the moment this
1613 doesn't save much memory in most situations: due to secondary
1614 expansion we actually save prerequisite lists twice (once before
1615 the secondary expansion, and then again after it's been parsed
1616 into individual file names in the dep list). We will resolve this
1617 in a future change, by doing the parsing up-front for targets
1618 where secondary expansion is not set.
1620 Moving things into the strcache also allows us to use const
1621 pointers in many more places.
1623 2007-01-03 Paul Smith <psmith@gnu.org>
1625 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1626 the function, not just the first. Fixes Savannah bug #18680.
1628 2006-11-18 Paul Smith <psmith@gnu.org>
1630 * strcache.c (strcache_add_len): Don't allocate a new buffer
1631 unless the string is not already nil-terminated. Technically this
1632 is a violation of the standard, since we may be passed an array
1633 that is not long enough to test one past. However, in make this
1634 is never true since we only use nil-terminated strings or
1635 sub-strings thereof.
1637 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1639 * main.c: New global cmd_prefix, defaults to '\t'.
1640 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1643 * dir.c: Constified.
1644 (dir_contents_file_exists_p): Check for an error return from
1645 readdir(), just in case.
1647 * commands.c: Constified.
1648 * default.c: Constified.
1649 * expand.c: Constified.
1650 * function.c: Partial constification.

1655 * w32/pathstuff.c: Partial constification.
1657 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1659 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1660 backslashes and drive letters as absolute.
1662 2006-10-22 Paul Smith <psmith@gnu.org>

1666 2006-10-21 Paul Smith <psmith@gnu.org>
1669 * arscan.c: Constified.
1671 2006-09-30 Paul Smith <psmith@gnu.org>
1673 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1674 point to lastword since the example was updated.
1675 Fixes Savannah bug #16304.
1676 (Secondary Expansion): Correct example description.
1677 Fixes Savannah bug #16468.
1678 (Makefile Contents): Clarify that comments cannot appear within
1679 variable references or function calls.
1680 Fixes Savannah bug #16577.
1681 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1682 Fixes Savannah bug #17701.
1683 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1685 prerequisites. Fixes Savannah bug #17880.
1686 (Rule Syntax): "lise" -> "list"
1687 (Multiple Rules): ... -> @dots{}
1688 (Splitting Lines): ditto.
1690 * remake.c (update_file_1): Prereqs that don't exist should be
1691 considered changed, for the purposes of $?.
1692 Fixes Savannah bug #16051.

1734 that don't have extended grep.
1735 (cvsclean): Use $(PERL) instead of perl.
1737 2006-04-09 Paul D. Smith <psmith@gnu.org>
1739 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1741 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1742 inner-scope variables don't mask outer-scope variables.

1803 Declare and define sh_chars_sh[].
1805 2006-03-23 Paul D. Smith <psmith@gnu.org>
1807 * configure.in: Look for build.sh.in in $srcdir so it will be
1808 built for remote configurations as well.
1810 * Makefile.am: Make sure to clean up build.sh during distclean.
1811 Fixes Savannah bug #16166.
1813 * misc.c (log_access): Takes a const char *.

1819 * implicit.c (pattern_search): Call set_file_variables only
1820 if we have prerequisites that need second expansion. Fixes
1821 Savannah bug #16140.
1823 2006-03-19 Paul D. Smith <psmith@gnu.org>
1825 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1826 memory on hosts that don't support it directly.

1829 make sure I don't forget any).
1831 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1833 (die): Cleanup code was removed from here; call the new function.
1834 (main): If we are re-execing, clean up the jobserver first so we
1835 don't leak file descriptors.

1841 allow multiple concurrent runs.
1842 Patch from Joseph Myers <joseph@codesourcery.com>
1844 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1846 * dep.h (struct dep): Add the stem field.
1847 * misc.c (alloc_dep, free_dep): New functions.
1848 (copy_dep_chain): Copy stem.
1849 (free_dep_chain): Use free_dep.
1850 * read.c (record_files): Store stem in the dependency line.
1851 * file.c (expand_deps): Use stem stored in the dependency line. Use
1852 free_dep_chain instead of free_ns_chain.
1853 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1854 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.

1864 (allocated_variable_append): Don't expand the final result.
1865 Fixes Savannah bug #15913.
1867 2006-03-09 Paul Smith <psmith@gnu.org>
1869 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1870 listed non-existent files as changed. Turns out there's a bug in
1871 the Linux kernel builds which means that this change causes
1872 everything to rebuild every time. We will re-introduce this fix
1873 in the next release, to give them time to fix their build system.
1874 Fixes Savannah bug #16002.
1875 Introduces Savannah bug #16051.
1877 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1892 2006-02-19 Paul D. Smith <psmith@gnu.org>
1894 * commands.c (set_file_variables): Realloc, not malloc, the static
1895 string values to avoid memory leaks.
1897 * expand.c (recursively_expand_for_file): Only set reading_file to
1898 an initialized value.
1900 * implicit.c (pattern_search): We need to make a copy of the stem
1901 if we get it from an intermediate dep, since those get freed.
1903 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1905 (enter_file) [VMS]: Ditto.

1910 * job.c (construct_command_argv_internal): Fix last change.
1912 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1913 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1914 the calls to _beginthreadex.
1916 * expand.c (recursively_expand_for_file): Initialize `save' to
1917 prevent compiler warnings.
1919 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1921 * job.c (construct_command_argv_internal): Don't create a temporary
1922 script/batch file if we are under -n. Call _setmode to switch the
1923 script file stream to text mode.
1925 2006-02-17 Paul D. Smith <psmith@gnu.org>
1927 * variable.c (merge_variable_set_lists): Don't try to merge the
1928 global_setlist. Not only is this useless, but it can lead to
1929 circularities in the linked list, if global_setlist->next in one
1930 list gets set to point to another list which also ends in

1934 2006-02-15 Paul D. Smith <psmith@gnu.org>
1936 Fix for Savannah bug #106.
1938 * expand.c (expanding_var): Keep track of which variable we're
1939 expanding. If no variable is being expanded, it's the same as
1941 * make.h (expanding_var): Declare it.
1942 * expand.c (recursively_expand_for_file): Set expanding_var to the
1943 current variable we're expanding, unless there's no file info in
1944 it (could happen if it comes from the command line or a default
1945 variable). Restore it before we exit.
1946 * expand.c (variable_expand_string): Use the expanding_var file
1947 info instead of the reading_file info.

1957 * read.c (eval): Even if the included filenames expands to the
1958 empty string we still need to free the allocated buffer.
1960 * implicit.c (pattern_search): If we allocated a variable set for
1961 an impossible file, free it.
1962 * variable.c (free_variable_set): New function.
1963 * variable.h: Declare it.
1965 * read.c (read_all_makefiles): Makefile names are kept in the
1966 strcache, so there's never any need to alloc/free them.
1969 * main.c (main): Add "archives" to the .FEATURES variable if
1970 archive support is enabled.
1971 * doc/make.texi (Special Variables): Document it.
1973 2006-02-13 Paul D. Smith <psmith@gnu.org>

1981 * (ALL FILES): Updated copyright and license notices.
1983 2006-02-10 Paul D. Smith <psmith@gnu.org>
1985 A new internal capability: the string cache is a read-only cache
1986 of strings, with a hash table interface for fast lookup. Nothing
1987 in the cache will ever be freed, so there's no need for reference
1988 counting, etc. This is the beginning of a full solution for
1989 Savannah bug #15182, but for now we only store makefile names here.
1991 * strcache.c: New file. Implement a read-only string cache.
1992 * make.h: Add prototypes for new functions.
1993 * main.c (initialize_global_hash_tables): Initialize the string cache.
1994 (print_data_base): Print string cache stats.
1995 * read.c (eval_makefile): Use the string cache to store makefile
1996 names. Rewrite the string allocation to be sure we free everything.
1998 2006-02-10 Eli Zaretskii <eliz@gnu.org>
2000 * dir.c (dir_contents_file_exists_p): Don't opendir if the
2001 directory time stamp didn't change, except on FAT filesystems.

2024 timestamp from -o or -W, use that instead of the real time.

2026 -W, don't overwrite it with the real mtime.

2045 * filedef.h (struct file): Add a new LAST pointer.
2047 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
2048 the comparison. For 64-bits systems the result of the subtraction
2049 might not fit into an int. Use comparison instead.
2050 Fixes Savannah bug #15534.
2052 * doc/make.texi: Update the chapter on writing commands to reflect
2053 the changes made in 3.81 for backslash/newline and SHELL handling.
2055 2006-02-01 Paul D. Smith <psmith@gnu.org>
2057 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
2058 variable st is not used when it's not initialized.

2073 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2075 * remake.c (update_goal_chain): Set g->changed instead of
2076 incrementing it, as it is only 8-bit wide, and could overflow if
2077 many commands got started in update_file.

2091 are already more children than sub_proc.c can handle, behave as if
2092 the load were too high.
2093 (start_job_command): Fix a typo in error message when process_easy
2096 2006-01-14 Eli Zaretskii <eliz@gnu.org>
2098 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
2099 the shell is not sh.exe.
2101 * job.c (create_batch_file): Renamed from create_batch_filename;
2102 all callers changed. Don't close the temporary file; return its
2103 file descriptor instead. New arg FD allows to return the file
2105 (construct_command_argv_internal): Use _fdopen instead of fopen to
2106 open the batch file.
2108 2006-01-04 Paul D. Smith <psmith@gnu.org>
2110 * readme.vms: Updates for case-insensitive VMS file systems from
2111 Hartmut Becker <Hartmut.Becker@hp.com>.
2112 * dir.c (vms_hash): Ditto.
2113 * vmsify.c (copyto): Ditto.
2114 * vmsfunctions.c (readdir): Ditto.
2116 * make.1: Add a section on the exit codes for make.
2118 * doc/make.texi: A number of minor updates to the documentation.
2120 2006-01-03 Paul D. Smith <psmith@gnu.org>
2122 * remake.c (update_file_1): Mark a prerequisite changed if it
2125 * read.c (eval): Be sure to strip off trailing whitespace from the
2126 prerequisites list properly. Also, initialize all fields in
2127 struct dep when creating a new one.
2129 2005-12-28 Paul D. Smith <psmith@gnu.org>
2131 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2132 disable warnings for MSC.
2133 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2135 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2137 * doc/make.texi (Execution): Add a footnote about changes in
2138 handling of backslash-newline sequences. Mention the differences
2139 on MS-DOS and MS-Windows.
2141 * NEWS: More details about building the MinGW port and a pointer
2142 to README.W32. Fix the section name that describes the new
2143 backward-incompatible processing of backslash-newline sequences.
2144 The special processing of SHELL set to "cmd" is only relevant to
2145 MS-Windows, not MS-DOS.
2147 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2149 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2150 to DWORD, to avoid compiler warnings.
2151 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2152 use %ld in format, to avoid compiler warnings.
2154 * doc/make.texi (Special Targets): Fix a typo.
2155 (Appending): Fix cross-reference to Setting.
2156 (Special Variables, Secondary Expansion, File Name Functions)
2157 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2158 periods after a sentence.
2159 (Execution): Add @: after "e.g.".
2160 (Environment): Fix punctuation.
2161 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2162 (Shell Function, Target-specific): Add @: after "vs."
2164 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2166 * read.c (record_target_var): Initialize variable's export field
2167 with v_default instead of leaving it "initialized" by whatever
2168 garbage happened to be on the heap.
2170 2005-12-12 Paul D. Smith <psmith@gnu.org>
2172 * make.1: Fix some display errors and document all existing options.
2173 Patch by Mike Frysinger <vapier@gentoo.org>.
2175 2005-12-11 Paul D. Smith <psmith@gnu.org>
2177 * implicit.c (pattern_search): If 2nd expansion is not set for
2178 this implicit rule, replace the pattern with the stem directly,
2179 and don't re-expand the variable list. Along with the other
2180 .SECONDEXPANSION changes below, fixes bug #13781.
2182 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2184 * implicit.c (pattern_search): Mark other files that this rule
2185 builds as targets so that they are not treated as intermediates
2186 by the pattern rule search algorithm. Fixes bug #13022.
2188 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2190 * remake.c (notice_finished_file): Propagate the change of
2191 modification time to all the double-colon entries only if
2192 it is the last one to be updated. Fixes bug #14334.
2194 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2196 * function.c (func_flavor): Implement the flavor function which
2197 returns the flavor of a variable.
2198 * doc/make.texi (Functions for Transforming Text): Document it.
2199 * NEWS: Add it to the list of new functions.
2201 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2203 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2205 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2206 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2208 2005-10-26 Paul Smith <psmith@gnu.org>
2210 * read.c (record_files): Don't set deps flags if there are no deps.
2211 * maintMakefile: We only need to build the templates when we are
2212 creating a distribution, so don't do it for "all".
2214 2005-10-24 Paul D. Smith <psmith@gnu.org>
2216 Make secondary expansion optional: its enabled by declaring the
2217 special target .SECONDEXPANSION.
2219 * NEWS: Update information on second expansion capabilities.
2220 * doc/make.texi (Secondary Expansion): Document the
2221 .SECONDEXPANSION special target and its behavior.
2222 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2223 prerequisite list was found in a static pattern rule.
2224 (free_dep_chain): Declare a prototype.
2225 * file.c (parse_prereqs): New function: break out some complexity
2227 (expand_deps): If we aren't doing second expansion, replace % with
2228 the stem for static pattern rules. Call the new function.
2229 * filedef.h (parse_prereqs): Declare a prototype.
2230 * implicit.c (pattern_search): Initialize the new staticpattern
2232 * main.c (second_expansion): Declare a global variable to remember
2233 if the special target has been seen. Initialize the new
2234 staticpattern field for prerequisites.
2235 * make.h: Extern for second_expansion.
2236 * misc.c (free_dep_chain): New function: frees a struct dep list.
2237 * read.c (read_all_makefiles): Initialize the staticpattern field.
2238 (eval_makefile): Ditto.
2239 (record_files): Check for the .SECONDEXPANSION target and set
2240 second_expansion global if it's found.
2241 Use the new free_dep_chain() instead of doing it by hand.
2242 Set the staticpattern field for prereqs of static pattern targets.
2244 2005-10-16 Paul D. Smith <psmith@gnu.org>
2246 * main.c (main): Set CURDIR to be a file variable instead of a
2247 default, so that values of CURDIR inherited from the environment
2248 won't override the make value.
2250 2005-09-26 Paul D. Smith <psmith@gnu.org>
2252 * job.c (construct_command_argv_internal): If the line is empty
2253 remember to free the temporary argv strings.
2256 2005-09-16 Paul D. Smith <psmith@gnu.org>
2258 * job.c (start_job_command): The noerror flag is a boolean (single
2259 bit); set it appropriately.
2260 Reported by Mark Eichin <eichin@metacarta.com>
2262 2005-08-29 Paul D. Smith <psmith@gnu.org>
2264 * function.c (func_error): On Windows, output from $(info ...)
2265 seems to come in the wrong order. Try to force it with fflush().
2267 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2269 * read.c (record_files): Move code that sets stem for static
2270 pattern rules out of the if (!two_colon) condition so it is
2271 also executed for two-colon rules. Fixes Savannah bug #13881.
2273 2005-08-08 Paul D. Smith <psmith@gnu.org>
2275 * make.h: Don't test that __STDC__ is non-0. Some compilers
2276 (Windows for example) set it to 0 to denote "ISO C + extensions".
2279 2005-08-07 Paul D. Smith <psmith@gnu.org>
2281 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2282 conditional (slightly different version of a fix from Eli).
2284 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2285 If make is running in parallel without -k and two jobs die in a
2286 row, but not too close to each other, then make will quit without
2287 waiting for the rest of the jobs to die.
2289 * main.c (die): Don't reset err before calling reap_children() the
2290 second time: we still want it to be in the error condition.
2291 * job.c (reap_children): Use a static variable, rather than err,
2292 to control whether or not the error message should be printed.
2294 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2296 * w32/subproc/sub_proc.c: Include signal.h.
2297 (process_pipe_io, process_file_io): Pass a pointer to a local
2298 DWORD variable to GetExitCodeProcess. If the exit code is
2299 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2301 * job.c [WINDOWS32]: Include windows.h.
2302 (main_thread) [WINDOWS32]: New global variable.
2303 (reap_children) [WINDOWS32]: Get the handle for the main thread
2304 and store it in main_thread.
2306 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2307 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2308 doing anything else. When we are done, close the main thread
2309 handle and exit with status 130.
2311 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2313 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2316 * main.c (find_and_set_default_shell): If found a DOSish shell,
2317 set sh_found and the value of default_shell, and report the
2318 findings in debug mode.
2320 * job.c (construct_command_argv_internal): Check unixy_shell, not
2321 no_default_sh_exe, to decide whether to use Unixy or DOSish
2324 * README.W32: Update with info about the MinGW build.
2326 * build_w32.bat: Support MinGW.
2328 * w32/subproc/build.bat: Likewise.
2330 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2331 printing DWORD args.
2333 * function.c (windows32_openpipe): Fix format strings for printing
2336 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2338 (start_job_command): Fix format string for printing the result of
2340 (start_job_command) [WINDOWS32]: Do not define.
2341 (exec_command): Fix format string for printing HANDLE args.
2343 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2344 to avoid compiler warnings.
2345 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2346 (Note: some of these fixes were submitted independently by J. Grant)
2348 2005-07-30 J. Grant <jg@jguk.org>
2350 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2351 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2352 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2354 2005-07-15 Paul Smith <psmith@gnu.org>
2356 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2357 we don't have a POSIX shell, then revert to the old
2358 backslash-newline behavior (where they are stripped).
2361 2005-07-08 Paul D. Smith <psmith@gnu.org>
2363 * config.h.W32.template: Reorder to match the standard config.h,
2364 for easier comparisons.
2365 From J. Grant <jg@jguk.org>
2367 * maintMakefile: Remove .dep_segment before overwriting it, in
2368 case it's not writable or noclobber is set.
2369 * expand.c (variable_expand_string): Cast result of pointer
2370 arithmetic to avoid a warning.
2371 * main.c (switches): Add full-fledged final initializer.
2373 2005-07-06 Paul D. Smith <psmith@gnu.org>
2375 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2376 * signame.c (strsignal): If we found _sys_siglist[] or
2377 __sys_siglist[] use those instead of sys_siglist[].
2378 From Albert Chin <china@thewrittenword.com>
2380 2005-07-04 Paul D. Smith <psmith@gnu.org>
2382 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2383 globfree(); set up to use the GNU versions.
2384 From Martin Zinser <zinser@zinser.no-ip.info>
2386 2005-07-03 Paul D. Smith <psmith@gnu.org>
2388 From J. Grant <jg@jguk.org>:
2390 * README.W32.template: Update the Windows and tested MSVC versions.
2391 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2392 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2393 * build_w32.bat: Ditto.
2394 * w32/subproc/build.bat: Ditto.
2396 2005-06-28 Paul D. Smith <psmith@gnu.org>
2398 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2399 declaration was checked but not present.
2401 2005-06-27 Paul D. Smith <psmith@gnu.org>
2403 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2404 to unsigned long. Fixes Savannah bug #13550.
2406 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2407 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2408 Fixes Savannah bug #13551.
2410 2005-06-26 Paul D. Smith <psmith@gnu.org>
2412 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2413 it if ANSI_STRING is not set.
2415 2005-06-25 Paul D. Smith <psmith@gnu.org>
2417 * read.c (eval): If no filenames are passed to any of the
2418 "include" variants, don't print an error.
2419 * doc/make.texi (Include): Document this.
2420 Fixes Savannah bug #1761.
2422 * job.c (construct_command_argv_internal): Sanitize handling of
2423 backslash/newline pairs according to POSIX: that is, keep the
2424 backslash-newline in the command script, but remove a following
2425 TAB character, if present. In the fast path, make sure that the
2426 behavior matches what the shell would do both inside and outside
2427 of quotes. In the slow path, quote the backslash and put a
2428 literal newline in the string.
2429 Fixes Savannah bug #1332.
2430 * doc/make.texi (Execution): Document the new behavior and give
2432 * NEWS: Make a note of the new behavior.
2434 * make.h [WINDOWS32]: #include <direct.h>.
2435 Fixes Savannah bug #13478.
2437 * remake.c (name_mtime): If the stat() of a file fails and the -L
2438 option was given and the file is a symlink, take the best mtime of
2439 the symlink we can get as the mtime of the file and don't fail.
2440 Fixes Savannah bug #13280.
2442 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2443 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2444 inside a variable reference. Make this function static as it's
2446 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2447 parsing an unexpanded line looking for semicolons.
2448 Fixes Savannah bug #1454.
2449 * misc.c (remove_comments): Move this to read.c and make it static
2450 as it's only used there. Call find_char_unquote() with new arg.
2451 * make.h: Remove prototypes for find_char_unquote() and
2452 remove_comments() since they're static now.
2454 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2455 its export flag and obtain its value. When we need to re-exec,
2456 increment the value and add it into the environment.
2457 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2458 * NEWS: Mention MAKE_RESTARTS.
2459 * main.c (always_make_set): New variable. Change the -B option to
2460 set this one instead.
2461 (main): When checking makefiles, only set always_make_flag if
2462 always_make_set is set AND the restarts flag is 0. When building
2463 normal targets, set it IFF always_make_set is set.
2464 (main): Avoid infinite recursion with -W, too: only set what-if
2465 files to NEW before we check makefiles if we've never restarted
2466 before. If we have restarted, set what-if files to NEW _after_ we
2468 Fixes Savannah bug #7566:
2470 2005-06-17 Paul D. Smith <psmith@gnu.org>
2472 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2473 in the prerequisites list.
2475 2005-06-12 Paul D. Smith <psmith@gnu.org>
2477 Fix Savannah bug # 1328.
2479 * configure.in: Check for atexit().
2480 * misc.c (close_stdout): Test stdout to see if writes to it have
2481 failed. If so, be sure to exit with a non-0 error code. Based on
2482 code found in gnulib.
2483 * make.h: Prototype.
2484 * main.c (main): Install close_stdout() with atexit().
2486 2005-06-10 Paul D. Smith <psmith@gnu.org>
2488 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2490 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2491 headers; make vmsWaitForChildren() static; extern vmsify().
2492 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2493 Don't create child_execute_job() here (it's in vmsjobs.c).
2494 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2496 2005-06-09 Paul D. Smith <psmith@gnu.org>
2498 * variable.c (push_new_variable_scope): File variables point
2499 directly to the global_setlist variable. So, inserting a new
2500 scope in front of that has no effect on those variables: they
2501 don't go through current_variable_set_list. If we're pushing a
2502 scope and the current scope is global, push it "the other way" so
2503 that the new setlist is in the global_setlist variable, and
2504 next points to a new setlist with the global variable set.
2505 (pop_variable_scope): Properly undo a push with the new
2507 Fixes Savannah bug #11913.
2509 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2511 * job.c (reap_children): Don't die of the command failed but
2512 the dontcare flag is set. Fixes Savannah bug #13216.
2514 * implicit.c (pattern_search): When creating a target from
2515 an implicit rule match, lookup pattern target and set precious
2516 flag in a newly created target. Fixes Savannah bug #13218.
2518 2005-05-13 Paul D. Smith <psmith@gnu.org>
2520 Implement "if... else if... endif" syntax.
2522 * read.c (eval): Push all checks for conditional words ("ifeq",
2523 "else", etc.) down into the conditional_line() function.
2524 (conditional_line): Rework to allow "else if..." clause. New
2525 return value -2 for lines which are not conditionals. The
2526 ignoring flag can now also be 2, which means "already parsed a
2527 true branch". If that value is seen no other branch of this
2528 conditional can be considered true. In the else parsing if there
2529 is extra text after the else, invoke conditional_line()
2530 recursively to see if it's another conditional. If not, it's an
2531 error. If so, raise the conditional value to this level instead
2532 of creating a new conditional nesting level. Special check for
2533 "else" and "endif", which aren't allowed on the "else" line.
2534 * doc/make.texi (Conditional Syntax): Document the new syntax.
2536 2005-05-09 Paul D. Smith <psmith@gnu.org>
2538 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2539 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2540 recurses to the w32 directory, even on non-Windows systems. Use
2541 the method suggested in the automake manual.
2542 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2543 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2545 2005-05-07 Paul D. Smith <psmith@gnu.org>
2547 * main.c (die): If we're dying with a fatal error (not that a
2548 command has failed), write back any leftover tokens before we go.
2550 * job.c (set_child_handler_action_flags): If there are jobs
2551 waiting for the load to go down, set an alarm to go off in 1
2552 second. This allows us to wake up from a potentially long-lasting
2553 read() and start a new job if the load has gone down. Turn it off
2555 (job_noop): Dummy signal handler function.
2556 (new_job): Invoke it with the new semantics.
2558 * docs/make.texi: Document secondary expansion. Various cleanups
2561 2005-05-03 Paul D. Smith <psmith@gnu.org>
2563 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2564 the targets which are to ultimately be made are called "goals";
2565 see the GNU make manual. Also, MAKECMDGOALS, etc.
2567 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2568 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2569 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2571 2005-05-02 Paul D. Smith <psmith@gnu.org>
2573 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2574 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2575 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2576 functions to vmsjobs.c. #include it into jobs.c.
2578 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2579 jobserver tokens. I found that this happens when an exported
2580 recursive variable contains a $(shell ...) function reference: in
2581 this situation we could "forget" to write back a token.
2583 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2584 we have. It's not reliable to depend on the number of children in
2585 our linked list so keep a separate count.
2586 (new_job): Check jobserver_tokens rather than children &&
2587 waiting_jobs. Increment jobserver_tokens when we get one.
2588 (free_child): If jobserver_tokens is 0, internal error. If it's
2589 >1, write a token back to the jobserver pipe (we don't write a
2590 token for the "free" job). Decrement jobserver_tokens.
2592 * main.c: Add variable master_job_slots.
2593 (main): Set it to hold the number of jobs requested if we're the
2594 master process, when using the jobserver.
2595 (die): Sanity checks: first test jobserver_tokens to make sure
2596 this process isn't holding any tokens we didn't write back.
2597 Second, if master_job_slots is set count the tokens left in the
2598 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2600 2005-04-24 Paul D. Smith <psmith@gnu.org>
2602 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2603 with -l# can lose jobserver tokens, because waiting jobs are not
2604 consulted properly when checking for the "free" token.
2606 * job.c (free_child): Count waiting_jobs as having tokens.
2607 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2608 handle jobs waiting for the load to drop.
2610 2005-04-23 Paul D. Smith <psmith@gnu.org>
2612 * main.c (main): Be careful to not core if a variable setting in
2613 the environment doesn't contain an '='. This is illegal but can
2614 happen in broken setups.
2615 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2617 2005-04-12 Paul D. Smith <psmith@gnu.org>
2619 The second expansion feature causes significant slowdown. Timing
2620 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2621 read the makefile before the feature, to 11+s to do the same
2622 operations after the feature. Additionally, memory usage
2623 increased drastically. To fix this I added some intelligence that
2624 avoids the overhead of the second expansion unless it's required.
2626 * dep.h: Add a new boolean field, need_2nd_expansion.
2628 * read.c (eval): When creating the struct dep for the target,
2629 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2630 (record_files): If there's a "%" in a static pattern rule, it gets
2631 converted to "$*" so set need_2nd_expansion to 1.
2633 * file.c (expand_deps): Rework to be more efficient. Only perform
2634 initialize_file_variables(), set_file_variables(), and
2635 variable_expand_for_file() if the need_2nd_expansion is set.
2637 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2638 (pattern_search): Ditto.
2639 * main.c (handle_non_switch_argument): Ditto.
2641 * read.c (read_all_makefiles): Ditto.
2642 (eval_makefile): Ditto.
2644 2005-04-07 Paul D. Smith <psmith@gnu.org>
2646 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2647 * variable.c (sync_Path_environment): Ditto.
2648 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2650 * main.c (main): Define the .FEATURES variable.
2651 * NEWS: Announce .FEATURES.
2652 * doc/make.texi (Special Variables): Document .FEATURES.
2654 * remake.c (check_dep): If a file is .PHONY, update it even if
2655 it's marked intermediate. Fixes Savannah bug #12331.
2657 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2659 * file.c (expand_deps): Factor out the second expansion and
2660 prerequisite line parsing logic from snap_deps().
2662 * file.c (snap_deps): Use expand_deps(). Expand and parse
2663 prerequisites of the .SUFFIXES special target first. Fixes
2664 Savannah bug #12320.
2666 2005-03-13 Paul D. Smith <psmith@gnu.org>
2668 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2671 2005-03-11 Paul D. Smith <psmith@gnu.org>
2673 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2674 available, not undefined (from Earnie Boyd).
2676 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2678 * implicit.c (pattern_search): Mark an intermediate target as
2679 precious if it happened to be a prerequisite of some (other)
2680 target. Fixes Savannah bug #12267.
2682 2005-03-09 Paul D. Smith <psmith@gnu.org>
2684 * read.c (eval_makefile): Add alloca(0).
2685 (eval_buffer): Ditto.
2687 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2689 * main.c (main): Use o_file instead of o_default when defining
2690 the .DEFAULT_TARGET special variable.
2691 * read.c (eval): Use define_variable_global() instead of
2692 define_variable() when setting new value for the .DEFAULT_TARGET
2693 special variable. Fixes Savannah bug #12266.
2695 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2697 * imlicit.c (pattern_search): Mark files for which an implicit
2698 rule has been found as targets. Fixes Savannah bug #12202.
2700 2005-03-04 Paul D. Smith <psmith@gnu.org>
2703 * doc/make.texi (Automatic Variables): Document $|.
2705 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2707 * read.c (record_files): Instead of substituting % with
2708 actual stem value in dependency list replace it with $*.
2709 This fixes stem triple expansion bug.
2711 * implicit.c (pattern_search): Copy stem to a separate
2712 buffer and make it a properly terminated string. Assign
2713 this buffer instead of STEM (which is not terminated) to
2714 f->stem. Instead of substituting % with actual stem value
2715 in dependency list replace it with $*. This fixes stem
2716 triple expansion bug.
2718 2005-03-01 Paul D. Smith <psmith@gnu.org>
2720 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2721 on Windows, as it takes a handle not a pid. Just exit.
2722 Fix from patch #3679, provided by Alessandro Vesely.
2724 * configure.in: Update check for sys_siglist[] from autoconf manual.
2725 * signame.c (strsignal): Update to use the new autoconf macro.
2727 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2729 * read.c (record_files): Add a check for the list of prerequisites
2730 of a static pattern rule being empty. Fixes Savannah bug #12180.
2732 2005-02-28 Paul D. Smith <psmith@gnu.org>
2734 * doc/make.texi (Text Functions): Update docs to allow the end
2735 ordinal for $(wordlist ...) to be 0.
2736 * function.c (func_wordlist): Fail if the start ordinal for
2737 $(wordlist ...) is <1. Matches documentation.
2738 Resolves Savannah support request #103195.
2740 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2741 previously we were stopping when !-q, exactly the opposite. This
2742 has been wrong since version 1.34, in 1994!
2743 (update_file): If we got an error don't break out to run more
2744 double-colon rules: just return immediately.
2745 Fixes Savannah bug #7144.
2747 2005-02-27 Paul D. Smith <psmith@gnu.org>
2749 * misc.c (end_of_token): Make argument const.
2750 * make.h: Update prototype.
2752 * function.c (abspath, func_realpath, func_abspath): Use
2753 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2754 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2755 * read.c (record_files): Ditto.
2756 * variable.c (do_variable_definition): Ditto.
2758 * function.c (func_error): Create a new function $(info ...) that
2759 simply prints the message to stdout with no extras.
2760 (function_table_init): Add new function to the table.
2761 * NEWS: Add $(info ...) reference.
2762 * doc/make.texi (Make Control Functions): Document it.
2764 New feature: if the system supports symbolic links, and the user
2765 provides the -L/--check-symlink-time flag, then use the latest
2766 mtime between the symlink(s) and the target file.
2768 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2769 readlink(). If both are available, define MAKE_SYMLINKS.
2770 * main.c: New variable: check_symlink_flag.
2771 (usage): Add a line for -L/--check-symlink-times to the help string.
2772 (switches): Add -L/--check-symlink-times command line argument.
2773 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2774 print a warning and disable it again.
2775 * make.h: Declare check_symlink_flag.
2776 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2777 if the file is a symlink then check each link in the chain and
2778 choose the NEWEST mtime we find as the mtime for the file. The
2779 newest mtime might be the file itself!
2780 * NEWS: Add information about this new feature.
2781 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2783 Avoid core dumps described in Savannah bug # 12124:
2785 * file.c: New variable snapped_deps remember whether we've run
2787 (snap_deps): Set it.
2788 * filedef.h: Extern it.
2789 * read.c (record_files): Check snapped_deps; if it's set then
2790 we're trying to eval a new target/prerequisite relationship from
2791 within a command script, which we don't support. Fatal.
2793 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2795 Implementation of the .DEFAULT_TARGET special variable.
2797 * read.c (eval): If necessary, update default_target_name when
2799 * read.c (record_files): Update default_target_file if
2800 default_target_name has changed.
2801 * main.c (default_target_name): Define.
2802 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2803 default_target_name is set use default_target_file as a root
2805 * filedef.h (default_target_name): Declare.
2806 * dep.h (free_dep_chain):
2807 * misc.c (free_dep_chain): Change to operate on struct nameseq
2808 and change name to free_ns_chain.
2809 * file.c (snap_deps): Update to use free_ns_chain.
2811 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2813 Implementation of the second expansion in explicit rules,
2814 static pattern rules and implicit rules.
2816 * read.c (eval): Refrain from chopping up rule's dependencies.
2817 Store them in a struct dep as a single dependency line. Remove
2818 the code that implements SySV-style automatic variables.
2820 * read.c (record_files): Adjust the code that handles static
2821 pattern rules to expand all percents instead of only the first
2822 one. Reverse the order in which dependencies are stored so that
2823 when the second expansion reverses them again they appear in
2824 the makefile order (with some exceptions, see comments in
2825 the code). Remove the code that implements SySV-style automatic
2828 * file.c (snap_deps): Implement the second expansion and chopping
2829 of dependency lines for explicit rules.
2831 * implicit.c (struct idep): Define an auxiliary data type to hold
2832 implicit rule's dependencies after stem substitution and
2835 * implicit.c (free_idep_chain): Implement.
2837 * implicit.c (get_next_word): Implement helper function for
2838 parsing implicit rule's dependency lines into words taking
2839 into account variable expansion requests. Used in the stem
2842 * implicit.c (pattern_search): Implement the second expansion
2843 for implicit rules. Also fixes bug #12091.
2845 * commands.h (set_file_variables): Declare.
2846 * commands.c (set_file_variables): Remove static specifier.
2848 * dep.h (free_dep_chain): Declare.
2849 * misc.c (free_dep_chain): Implement.
2851 * variable.h (variable_expand_for_file): Declare.
2852 * expand.c (variable_expand_for_file): Remove static specifier.
2854 * make.h (strip_whitespace): Declare.
2855 * function.c (strip_whitespace): Remove static specifier.
2857 2005-02-26 Paul D. Smith <psmith@gnu.org>
2859 * main.c (main): Check for ferror() when reading makefiles from stdin.
2860 Apparently some shells in Windows don't close pipes properly and
2863 2005-02-24 Jonathan Grant <jg@jguk.org>
2865 * configure.in: Add MinGW configuration options, and extra w32 code
2867 * Makefile.am: Add MinGW configuration options, and extra w32 code
2869 * main.c: Determine correct program string (after last \ without .exe).
2870 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2872 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2873 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2874 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2875 environment support.
2877 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2879 * function.c (func_shell): When initializing error_prefix, check
2880 that reading file name is not null. This fixes long-standing
2881 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2883 2005-02-09 Paul D. Smith <psmith@gnu.org>
2885 * maintMakefile: Update the CVS download URL to simplify them.
2886 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2887 downloading the .texi files from Savannah now.
2889 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2891 * main.c (handle_non_switch_argument): Only add variables to
2892 command_variables if they're not already there: duplicate settings
2893 waste space and can be confusing to read.
2895 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2896 this header is never included by non-WINDOWS32 code, and it
2897 requires <config.h> to define which isn't always included first.
2899 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2900 testing MINGW32 versions.
2902 * main.c (log_working_directory): flush stdout to be sure the WD
2903 change is printed before any stderr messages show up.
2905 2005-02-01 Paul D. Smith <psmith@gnu.org>
2907 * maintMakefile (po_repo): Update the GNU translation site URL.
2909 2004-12-01 Paul D. Smith <psmith@gnu.org>
2911 * main.c (main): Change char* env_shell to struct variable shell_var.
2912 * variable.c (target_environment): Use new shell_var.
2914 2004-11-30 Paul D. Smith <psmith@gnu.org>
2916 * configure.in: The old way we avoided creating build.sh from
2917 build.sh.in before build.sh.in exists doesn't work anymore; we
2918 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2919 the help!). This also keeps automake from complaining.
2920 * Makefile.am (README): Add a dummy target so automake won't
2921 complain that this file doesn't exist when we checkout from CVS.
2922 * maintMakefile (.dep_segment): Rewrite this rule since newer
2923 versions of automake don't provide DEP_FILES.
2925 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2927 Implementation of `realpath' and `abspath' built-in functions.
2929 * configure.in: Check for realpath.
2930 * function.c (abspath): Return an absolute file name that does
2931 not contain any `.' or `..' components, nor repeated `/'.
2932 * function.c (func_abspath): For each name call abspath.
2933 * function.c (func_realpath): For each name call realpath
2934 from libc or delegate to abspath if realpath is not available.
2935 * doc/make.texi (Functions for File Names): Document new functions.
2936 * doc/make.texi (Quick Reference): Ditto.
2938 2004-11-28 Paul D. Smith <psmith@gnu.org>
2940 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2941 arguments. Fixes bug #10252.
2943 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2945 * main.c (main): Set SHELL to v_noexport by default. Remember the
2946 original environment setting of SHELL in the env_shell variable.
2947 * main.h: Export new env_shell variable.
2948 * variable.c (target_environment): If we find a v_noexport
2949 variable for SHELL, add a SHELL variable with the env_shell value.
2950 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2951 * doc/make.texi (Variables/Recursion): Ditto.
2953 2004-11-28 Paul D. Smith <psmith@gnu.org>
2955 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2956 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2957 Patch by Alessandro Vesely.
2959 2004-11-12 Paul D. Smith <psmith@gnu.org>
2961 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2962 the command line if it's inside a string.
2963 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2965 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2967 * function.c (func_lastword): New function: return last word
2968 from the list of words.
2969 * doc/make.texi: Document $(lastword ). Fix broken links in
2970 Quick Reference section.
2972 2004-10-06 Paul D. Smith <psmith@gnu.org>
2974 Apply patch from Alessandro Vesely, provided with bug # 9748.
2975 Fix use of tmpnam() to work with Borland C.
2977 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2978 construction of a temporary filename, and call new function
2979 create_batch_filename().
2980 (create_batch_filename) [WINDOWS32]: New function to create a
2983 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2985 * read.c (record_target_var): Expand simple pattern-specific
2987 * variable.c (initialize_file_variables): Do not expand simple
2988 pattern-specific variable.
2990 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2992 * remake.c (update_file_1): When rebuilding makefiles inherit
2993 dontcare flag from a target that triggered update.
2995 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2997 * variable.c (initialize_file_variables): Mark pattern-specific
2998 variable as a per-target and copy export status.
3000 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
3002 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
3004 * implicit.c (pattern_search): When considering an implicit rule's
3005 prerequisite check that it is actually a target rather then
3006 just an entry in the file hashtable.
3008 2004-09-21 Paul D. Smith <psmith@gnu.org>
3010 * read.c (readstring): Fix some logic errors in backslash handling.
3011 (eval): Remove some unnecessary processing in buffer handling.
3012 (record_target_var): Assert that parse_variable_definition() succeeded.
3013 Reported by: Markus Mauhart <qwe123@chello.at>.
3015 * misc.c: Removed the sindex() function. All instances of this
3016 function were trivially replaceable by the standard strstr()
3017 function, and that function will always have better (or certainly
3018 no worse) performance than the very simple-minded algorithm
3019 sindex() used. This can matter with complex makefiles.
3020 * make.h: Remove the prototype for sindex().
3021 * function.c (subst_expand): Convert sindex() call to strstr().
3022 This means we no longer need to track the TLEN value so remove that.
3023 (func_findstring): Convert sindex() to strstr().
3024 * commands.c (chop_commands): Convert sindex() calls to strstr().
3025 Suggested by: Markus Mauhart <qwe123@chello.at>.
3027 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
3028 idea behind Savannah Patch #3144 from david.baird@homemail.com.
3029 If SHELL is set to CMD.EXE then assume it's batch-mode and
3030 non-unixy. I wrote the code differently from the patch, though,
3031 to make it safer. This also resolves bug #9174.
3033 2004-09-20 Paul D. Smith <psmith@gnu.org>
3035 * expand.c (variable_expand_string): Modify to invoke
3036 patsubst_expand() instead of subst_expand(); the latter didn't
3037 handle suffix patterns correctly.
3038 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
3039 was used only from variable_expand_string() and is no longer used
3041 (func_subst): Ditto, on call to subst_expand().
3042 (patsubst_expand): Require the percent pointers to point to the
3043 character after the %, not to the % itself.
3044 * read.c (record_files): New call criteria for patsubst_expand().
3045 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
3046 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
3048 2004-09-19 Paul D. Smith <psmith@gnu.org>
3050 * function.c (subst_expand): Fix a check in by_word: look for a
3051 previous blank if we're beyond the beginning of the string, not
3052 the beginning of the word.
3053 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3055 2004-05-16 Paul D. Smith <psmith@gnu.org>
3057 * remake.c (update_goal_chain): Change the argument specifying
3058 whether we're rebuilding makefiles to be a global variable,
3059 REBUILDING_MAKEFILES.
3060 (complain): Extract the code that complains about no rules to make
3061 a target into a separate function.
3062 (update_file_1): If we tried to rebuild a file during the makefile
3063 rebuild phase and it was dontcare, then no message was printed.
3064 If we then try to build the same file during the normal build,
3065 print a message this time.
3066 (remake_file): Don't complain about un-remake-able files when
3067 we're rebuilding makefiles.
3069 2004-05-11 Paul D. Smith <psmith@gnu.org>
3071 * job.c (construct_command_argv_internal): OS/2 patches from
3072 Andreas Buening <andreas.buening@nexgo.de>.
3074 2004-05-10 Paul D. Smith <psmith@gnu.org>
3076 * remake.c (update_file): Don't walk the double-colon chain unless
3077 this is a double-colon rule. Fix suggested by Boris Kolpackov
3078 <boris@kolpackov.net>.
3080 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3081 * readme.vms: New section describing OpenVMS support and issues.
3082 * default.c (default_variables): Add support for IA64.
3083 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3084 without some privilege aborts make with the error
3085 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3086 pressing Ctrl+Y and the input device is no terminal. The change
3087 catches this error and just continues.
3089 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3091 2004-04-25 Paul D. Smith <psmith@gnu.org>
3093 * commands.c (set_file_variables): Set $< properly in the face of
3094 order-only prerequisites.
3095 Patch from Boris Kolpackov <boris@kolpackov.net>
3097 2004-04-21 Bob Byrnes <byrnes@curl.com>
3099 * main.c (main): Notice failures to remake makefiles.
3101 2004-03-28 Paul D. Smith <psmith@gnu.org>
3103 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3105 * job.c: No default shell for RISC OS.
3106 (load_too_high): Hard-code the return to 1.
3107 (construct_command_argv_internal): No sh_chars or sh_cmds.
3108 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3110 2004-03-20 Paul D. Smith <psmith@gnu.org>
3112 * variable.c (do_variable_definition): Don't append from the
3113 global set if a previous non-appending target-specific variable
3114 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3117 * expand.c (reference_variable): Don't give up on variables with
3118 no value that have the target-specific append flag set: they might
3119 have a value after all. Reported by Oliver Schmidt
3120 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3121 <nikulin@dx1cmd.inp.nsk.su>.
3123 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3124 refer to absolute pathnames in directories that don't exist: some
3125 portion of the makefile could create those directories before we
3126 match the pattern. Fixes bugs #775 and #108.
3128 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3130 * main.c (main): Free makefile_mtimes if we have any.
3131 * README.W32.template: Update documentation for the current status
3132 of the MS-Windows port.
3133 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3134 environment variable is sometimes already defined which causes the
3136 * main.c (debug_signal_handler): Only define this function if
3137 SIGUSR1 is available.
3139 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3141 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3142 * README.OS2.template: Documentation updates.
3143 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3144 link line for safety.
3145 * maintMakefile (build.sh.in): Remove an extraneous ")".
3146 * job.c (child_execute_job): Close saved FDs.
3147 * job.c (exec_command) [OS/2]: exec_command(): If the command
3148 can't be exec'ed and if the shell is not Unix-sh, then try again
3149 with argv = { "cmd", "/c", ... }. Normally, this code is never
3150 reached for the cmd shell unless the command really doesn't exist.
3151 (construct_command_argv_internal) [OS/2]: The code for cmd
3152 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3153 The CMD builtin commands are case insensitive so use strcasecmp().
3155 2004-03-19 Paul D. Smith <psmith@gnu.org>
3157 * read.c (do_define): Re-order line counter increment so the count
3158 is accurate (we were losing one line per define). Reported by
3159 Dave Yost <Dave@Yost.com>.
3161 2004-03-06 Paul D. Smith <psmith@gnu.org>
3163 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3165 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3166 * misc.c (message,error,fatal): Ditto.
3167 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3168 * config.h.W32.template: Ditto.
3169 * config.h-vms.template: Ditto.
3170 * config.ami.template: Ditto.
3172 2004-03-04 Paul D. Smith <psmith@gnu.org>
3174 * README.template: Add a note about broken /bin/sh on SunOS
3175 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3177 * misc.c (message, error, fatal): Don't use "..." if we're using
3178 varargs. ansi2knr should handle this but it doesn't work: it
3179 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3180 done. On many systems (SunOS for example) va_dcl is a #define.
3181 So, force the use of the non-"..." version on pre-ANSI compilers.
3183 * maintMakefile (sign-dist): Create some rules to help automate
3184 the new GNU ftp upload method.
3186 2004-02-24 Paul D. Smith <psmith@gnu.org>
3188 * config.h.W32.template: Add HAVE_STDARG_H
3189 * config.h-vms.template: Ditto.
3190 * config.ami.template: Ditto.
3192 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3194 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3195 * build_w32.bat: Remove extra "+".
3197 2004-02-23 Paul D. Smith <psmith@gnu.org>
3199 * make.h: Create an UNUSED macro to mark unused parameters.
3200 * (many): Clean up warnings by applying UNUSED, fixing
3201 signed/unsigned incompatibilities, etc.
3203 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3205 * filedef.h: Name the command_state enumeration.
3206 * file.c (set_command_state): Use the enumeration in the function
3209 * configure.in: Explicitly set SET_MAKE to empty, to disable
3210 MAKE=make even when no make already exists. Fix bug #3823.
3212 2004-02-22 Paul D. Smith <psmith@gnu.org>
3214 * maintMakefile: Perl script to clean up all non-CVS files. Use
3215 it on all the subdirectories for the cvs-clean target.
3217 * main.c (decode_switches): Require non-empty strings for all our
3218 string command-line options. Fixes Debian bug # 164165.
3220 * configure.in: Check for stdarg.h and varargs.h.
3221 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3222 for printing messages.
3223 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3228 A number of patches for OS/2 support from Andreas Buening
3229 <andreas.buening@nexgo.de>:
3231 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3232 disable the SIGCHLD handler.
3233 (reap_children) [OS/2]: Remove special handling of job_rfd.
3234 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3235 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3236 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3237 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3238 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3241 2004-02-21 Paul D. Smith <psmith@gnu.org>
3243 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3244 <mail@kristov.de> reports that if process_begin() fails we don't
3245 handle the error condition correctly in all cases.
3246 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3247 to have a newline on the message.
3249 * job.c (construct_command_argv_internal): Add "test" to UNIX
3250 sh_cmds[]. Fixes Savannah bug # 7606.
3252 2004-02-04 Paul D. Smith <psmith@gnu.org>
3254 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3255 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3256 Hartmut Becker <Hartmut.Becker@hp.com>.
3258 2004-01-21 Paul D. Smith <psmith@gnu.org>
3260 * job.c (load_too_high): Implement an algorithm to control the
3261 "thundering herd" problem when using -l to control job creation
3262 via the load average. The system only recomputes the load once a
3263 second but we can start many jobs in a second. To solve this we
3264 keep track of the number of jobs started in the last second and
3265 apply a weight to try to guess what a correct load would be.
3266 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3267 Also fixes bug #4693.
3268 (reap_children): Decrease the job count for this second.
3269 (start_job_command): Increase the job count for this second.
3271 * read.c (conditional_line): Expand the text after ifn?def before
3272 checking to see if it's a single word. Fixes bug #7257.
3274 2004-01-09 Paul D. Smith <psmith@gnu.org>
3276 * file.c (print_file): Recurse to print all targets in
3277 double-colon rules. Fixes bug #4518, reported (with patch) by
3278 Andrew Chatham <chatham@google.com>.
3280 2004-01-07 Paul D. Smith <psmith@gnu.org>
3282 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3283 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3284 AC_FUNC_SETVBUF_REVERSED.
3286 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3287 (MAKE Variable): Fix Savannah bug #4898.
3289 * job.c (construct_command_argv_internal): Add "!" to the list of
3290 shell escape chars. POSIX sh allows it to appear before a
3291 command, to negate the exit code. Fixes bug #6404.
3293 * implicit.c (pattern_search): When matching an implicit rule,
3294 remember which dependencies have the ignore_mtime flag set.
3295 Original fix provided in Savannah patch #2349, by Benoit
3296 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3298 2003-11-22 Paul D. Smith <psmith@gnu.org>
3300 * README.W32.template (Outputs): Clarification on -j with
3301 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3304 2003-11-02 Paul D. Smith <psmith@gnu.org>
3306 * function.c (func_if): Strip all the trailing whitespace from the
3307 condition, then don't expand it. Fixed bug # 5798.
3309 * expand.c (recursively_expand_for_file): If we're expanding a
3310 variable with no file context, then use the variable's context.
3313 2003-10-21 Paul D. Smith <psmith@gnu.org>
3315 * main.c (log_working_directory): Add newlines to printf()s.
3317 * README.cvs: Add a note to ignore warnings during autoreconf.
3319 * maintMakefile (po_repo): Set a new URL for PO file updates.
3320 (get-config/config.guess get-config/config.sub): Get these files
3321 from the Savannah config project instead of ftp.gnu.org.
3323 2003-10-05 Paul Eggert <eggert@twinsun.com>
3325 * main.c (main): Avoid potential subscript error if environ has
3328 2003-08-22 Paul D. Smith <psmith@gnu.org>
3330 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3331 systems which don't yet implement the C89 standard :-/.
3333 2003-07-18 Paul D. Smith <psmith@gnu.org>
3335 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3336 [WINDOWS32]: Initialize hash.
3338 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3340 * dir.c (read_dirstream): Provide a workaround for broken versions of
3341 the MinGW dirent structure.
3343 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3345 * w32/include/dirent.h: Add __MINGW32__ filter.
3347 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3349 * make.h: Add global declaration of *make_host.
3350 * main.c (print_usage): Remove local declaration of *make_host.
3351 (print_version): Display "This program built for ..." after Copyright
3354 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3356 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3357 execution of "makeinfo --html make.texi".
3359 2003-04-30 Paul D. Smith <psmith@gnu.org>
3361 * build.template: Make some changes to maybe allow this script to
3362 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3364 * README.OS2.template: New file for OS/2 support. Original
3365 contributed by Andreas Buening.
3366 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3369 2003-04-19 Paul D. Smith <psmith@gnu.org>
3371 Fix bug #1405: allow a target to match multiple pattern-specific
3374 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3375 variable.c, where they've always belonged.
3376 * rule.h: Move the prototypes and struct pattern_var as well.
3377 * variable.c (initialize_file_variables): Invoke
3378 lookup_pattern_var() in a loop, until no more matches are found.
3379 If a match is found, create a new variable set for the target's
3380 pattern variables. Then merge the contents of each matching
3381 pattern variable set into the target's pattern variable set.
3382 (lookup_pattern_var): Change this function to be usable
3383 in a loop. It takes a starting position: if NULL, start at the
3384 beginning; if non-NULL, start with the pattern variable after that
3385 position, and return the next matching pattern.
3386 (create_pattern_var): Create a unique instance of
3387 pattern-specific variables for every definition in the makefile.
3388 Don't combine the same pattern together. This allows us to
3389 process the variable handling properly even when the same pattern
3390 is used multiple times.
3391 (parse_variable_definition): New function: break out the parsing
3392 of a variable definition line from try_variable_definition.
3393 (try_variable_definition): Call parse_variable_definition to
3395 (print_variable_data_base): Print out pattern-specific variables.
3396 * variable.h (struct variable): Remember when a variable is
3397 conditional. Also remember its flavor.
3398 (struct pattern_var): Instead of keeping a variable set, we just
3399 keep a single variable for each pattern.
3400 * read.c (record_target_var): Each pattern variable contains only a
3401 single variable, not a set, so create it properly.
3402 * doc/make.texi (Pattern-specific): Document the new behavior.
3404 2003-04-17 Paul D. Smith <psmith@gnu.org>
3406 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3407 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3408 file/directory naming rules for VMS so I can't tell whether this
3411 2003-04-09 Paul D. Smith <psmith@gnu.org>
3413 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3414 DOS-style pathnames: backslash separators and drive specifiers.
3416 2003-03-28 Paul D. Smith <psmith@gnu.org>
3418 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3419 the intermediate flag on all targets. Fixes bug #2515.
3421 2003-03-24 Paul D. Smith <psmith@gnu.org>
3423 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3424 Upgrade to autoconf 2.57 and automake 1.7.3.
3426 * job.c: More OS/2 changes from Andreas Buening.
3428 * file.c (print_file): Fix variable initialization.
3431 * remake.c (notice_finished_file):
3433 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3434 some calls (like readdir()) return NULL in valid situations
3435 without resetting errno. Fixes bug #2846.
3437 2003-02-25 Paul D. Smith <psmith@gnu.org>
3439 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3441 * job.c (_is_unixy_shell) [OS/2]: New function.
3442 Set default shell to /bin/sh.
3443 (reap_children): Close the job_rfd pipe here since we don't use a
3445 (set_child_handler_action_flags): define this to empty on OS/2.
3446 (start_job_command): Close the jobserver pipe and use
3447 child_execute_job() instead of fork/exec.
3448 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3449 rather than exec'ing, then reconfigure stdin/stdout.
3450 (exec_command): Rewrite to use spawn instead of exec. Return the
3453 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3454 in DOS. Handle the TEMP environment variable as in DOS. Don't
3455 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3456 use -j in DOS mode. Use child_execute_job() instead of
3459 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3462 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3463 prototypes that return values.
3465 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3467 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3468 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3470 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3473 2003-02-24 Paul D. Smith <psmith@gnu.org>
3475 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3476 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3477 (child_execute_job) [VMS]: Handle error status properly.
3478 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3480 * function.c (func_shell): Use EINTRLOOP() while reading from the
3481 subshell pipe (Fixes bug #2502).
3482 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3484 * main.c (main): Ditto.
3486 2003-01-30 Paul D. Smith <psmith@gnu.org>
3488 * read.c (eval): eval() was not fully reentrant, because the
3489 collapsed buffer was static. Change it to be an automatic
3490 variable so that eval() can be invoked recursively.
3492 (eval): Apply patch # 1022: fix memory reference error on long
3493 target-specific variable lines.
3494 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3496 * function.c (check_numeric): Combine the is_numeric() function
3497 into this function, since it's only called from one place.
3498 Constify this function. Have it print the incorrect string in the
3499 error message. Fixes bug #2407.
3500 (strip_whitespace): Constify.
3501 (func_if): Constify.
3502 * expand.c (expand_argument): Constify.
3504 2003-01-29 Paul D. Smith <psmith@gnu.org>
3506 Fix bug # 2169, also reported by other people on various systems.
3508 * make.h: Some systems, such as Solaris and PTX, do not fully
3509 implement POSIX-compliant SA_RESTART functionality; important
3510 system calls like stat() and readdir() can still fail with EINTR
3511 even if SA_RESTART has been set on the signal handler. So,
3512 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3513 EINTR for system calls which return -1 or 0 (NULL), respectively,
3515 Also, remove the old atomic_stat()/atomic_readdir() and
3516 HAVE_BROKEN_RESTART handling.
3518 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3520 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3521 * remake.c (touch_file): Ditto.
3523 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3524 * read.c (construct_include_path): Ditto.
3525 * remake.c (name_mtime): Ditto.
3526 * vpath.c (selective_vpath_search): Ditto.
3527 * dir.c (find_directory): Ditto.
3528 (local_stat): Ditto.
3529 (find_directory): Use ENULLLOOP() to wrap opendir().
3530 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3532 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3533 atomic_readdir() handling.
3535 2003-01-22 Paul D. Smith <psmith@gnu.org>
3537 * function.c (func_call): Fix Bug #1744. If we're inside a
3538 recursive invocation of $(call ...), mask any of the outer
3539 invocation's arguments that aren't used by this one, so that this
3540 invocation doesn't "inherit" them accidentally.
3542 2002-12-05 Paul D. Smith <psmith@gnu.org>
3544 * function.c (subst_expand): Valery Khamenia reported a
3545 pathological performance hit when doing substitutions on very
3546 large values with lots of words: turns out we were invoking
3547 strlen() a ridiculous number of times. Instead of having each
3548 call to sindex() call strlen() again, keep track of how much of
3549 the text we've seen and pass the length to sindex().
3551 2002-11-19 Paul D. Smith <psmith@gnu.org>
3553 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3556 2002-11-16 Paul D. Smith <psmith@gnu.org>
3558 * NMakefile.template (OBJS): Add hash.c object file.
3559 * SMakefile.template (srcs): Ditto.
3560 * Makefile.ami (objs): Ditto.
3561 * build_w32.bat: Ditto.
3563 * Makefile.DOS.template: Remove extra dependencies.
3565 2002-10-25 Paul D. Smith <psmith@gnu.org>
3567 * expand.c (install_variable_buffer): New function. Install a new
3568 variable_buffer context and return the previous one.
3569 (restore_variable_buffer): New function. Free the current
3570 variable_buffer context and put a previously saved one back.
3571 * variable.h: Prototypes for {install,restore}_variable_buffer.
3572 * function.c (func_eval): Push a new variable_buffer context
3573 before we eval, then restore the old one when we're done.
3576 * read.c (install_conditionals): New function. Install a new
3577 conditional context and return the previous one.
3578 (restore_conditionals): New function. Free the current
3579 conditional context and put a previously saved one back.
3580 (eval): Use the {install,restore}_conditionals for "include"
3582 (eval_buffer): Use {install,restore}_conditionals to preserve the
3583 present conditional state before we evaluate the buffer.
3586 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3588 (Recursion): Add a variable index entry for CURDIR.
3590 * README.cvs: Update to appropriate versions.
3591 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3592 don't need to copy loadavg.c: automake is smart enough to create
3593 it for me. Still have a bug in automake related to ansi2knr tho.
3595 2002-10-14 Paul D. Smith <psmith@gnu.org>
3597 * remake.c (notice_finished_file): Only touch targets if they have
3598 at least one command (as per POSIX). Resolve Bug #1418.
3600 * *.c: Convert to using ANSI C-style function definitions.
3601 * Makefile.am: Enable the ansi2knr feature of automake.
3602 * configure.in: ditto.
3604 2002-10-13 Paul D. Smith <psmith@gnu.org>
3606 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3607 for automatic variable values like $^, etc. In the case of very
3608 large lists of prerequisites this causes problems. Instead reuse
3609 a static buffer (resizeable) for each variable.
3611 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3612 target-specific variable definitions. Check for it and set an
3614 (record_target_var): Set the export field to v_export if the
3615 "exported" flag is set.
3616 * doc/make.texi (Target-specific): Document the ability to use
3619 * doc/make.texi: Change the name of the section on automatic
3620 variables from "Automatic" to "Automatic Variables". Added text
3621 clarifying the scope of automatic variables.
3623 2002-10-04 Paul D. Smith <psmith@gnu.org>
3625 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3627 (record_files): Ditto.
3629 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3630 the search for the '=' to only within the enclosing parens.
3632 2002-10-03 Paul D. Smith <psmith@gnu.org>
3634 Version 3.80 released.
3636 * dir.c: Change hash functions to use K&R function definition style.
3637 * function.c: Ditto.
3639 * variable.c: Ditto.
3641 Update to automake 1.7.
3643 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3644 (pdf): Remove this target as automake now provides one.
3646 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3648 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3650 * makefile.com: Updates for GNU make 3.80.
3651 * makefile.vms: Ditto.
3653 2002-09-23 Paul D. Smith <psmith@gnu.org>
3655 * read.c (enum make_word_type): Remove w_comment.
3656 (get_next_mword): Don't treat comment characters as special; where
3657 this function is used we will never see a comment (it's stripped
3658 before we get here) and treating comments specially means that
3659 targets like "foo\#bar" aren't handled properly.
3661 2002-09-18 Paul D. Smith <psmith@gnu.org>
3663 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3665 * read.c (eval): Expansion of arguments to export/unexport was
3666 ignoring all arguments after the first one. Change the algorithm
3667 to expand the whole line once, then parse the results.
3669 2002-09-17 Paul D. Smith <psmith@gnu.org>
3671 Fix Bug #940 (plus another bug I found while looking at this):
3673 * read.c (record_target_var): enter_file() will add a new entry if
3674 it's a double-colon target: we don't want to do that in this
3675 situation. Invoke lookup_file() and only enter_file() if it does
3676 not already exist. If the file we get back is a double-colon then
3677 add this variable to the "root" double-colon target.
3679 * variable.c (initialize_file_variables): If this file is a
3680 double-colon target but is not the "root" target, then initialize
3681 the root and make the root's variable list the parent of our
3684 2002-09-13 Paul D. Smith <psmith@gnu.org>
3686 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3688 * hash.c (round_up_2): Get rid of a warning.
3690 2002-09-12 Paul D. Smith <psmith@gnu.org>
3692 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3693 so it doesn't complain about getloadavg.c.
3695 * commands.c (set_file_variables): Make sure we always alloca() at
3696 least 1 character for the value of $? (for '\0').
3698 2002-09-11 Paul D. Smith <psmith@gnu.org>
3700 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3701 macro to use RESULT instead of the incorrect _RESULT_.
3703 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3704 and atomic_readdir(). We need to #include dirent.h to get this to
3706 * misc.c (atomic_readdir): Fix typos.
3708 2002-09-10 Paul D. Smith <psmith@gnu.org>
3710 * read.c (eval): Expand variable lists given to export and
3711 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3712 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3714 * doc/make.texi (Variables/Recursion): Document this.
3715 (Conditional Syntax): And here.
3717 2002-09-09 Paul D. Smith <psmith@gnu.org>
3719 * configure.in: Check for memmove().
3721 2002-09-07 Paul D. Smith <psmith@gnu.org>
3723 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3724 Michael Sterrett <msterret@coat.com> reports that while it has
3725 SA_RESTART, it does not work properly.
3727 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3728 that invokes stat() and loops to do it again if it returns EINTR.
3729 (atomic_readdir): Ditto, with readdir().
3731 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3732 and readdir() to atomic_stat() and atomic_readdir().
3734 2002-09-04 Paul D. Smith <psmith@gnu.org>
3736 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3737 reports that GNU make sometimes doesn't recognize that targets can
3738 be made, when directories can be created as prerequisites. He
3739 reports that changing the order of predicates in the DEP->changed
3740 flag test so that lookup_file() is always performed, solves this
3743 2002-08-08 Paul D. Smith <psmith@gnu.org>
3745 * configure.in: Require a newer version of gettext.
3747 * misc.c (perror_with_name): Translate the format string (for
3748 right-to-left language support).
3749 (pfatal_with_name): Ditto.
3751 * main.c: Create a static array of strings to store the usage
3752 text. This is done to facilitate translations.
3753 (struct command_switch): Remove argdesc and description fields.
3754 (switches): Remove values for obsolete fields.
3755 (print_usage): Print each element of the usage array.
3757 * hash.c: Change function definitions to be K&R style.
3759 2002-08-02 Paul D. Smith <psmith@gnu.org>
3761 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3762 this one because it's too hard to get right. We'll look at it for
3764 * main.c (main): Don't create the .TARGETS variable.
3765 * variable.c (handle_special_var): Don't handle .TARGETS.
3767 2002-08-01 Paul D. Smith <psmith@gnu.org>
3769 * main.c (switches): Add a new option, -B (--always-make). If
3770 specified, make will rebuild all targets that it encounters even
3771 if they don't appear to be out of date.
3772 (always_make_flag): New flag.
3773 * make.h: Extern always_make_flag.
3774 * remake.c (update_file_1): Check always_make_flag; if it's set we
3775 will always rebuild any target we can, even if none of its
3776 prerequisites are newer.
3779 * doc/make.texi (Shell Function): Make it clear that make
3780 variables marked as "export" are not passed to instances of the
3783 Add new introspection variable .VARIABLES and .TARGETS.
3785 * variable.c (handle_special_var): New function. If the variable
3786 reference passed in is "special" (.VARIABLES or .TARGETS),
3787 calculate the new value if necessary. .VARIABLES is handled here:
3788 walk through the hash of defined variables and construct a value
3789 which is a list of the names. .TARGETS is handled by
3790 build_target_list().
3791 (lookup_variable): Invoke handle_special_var().
3792 * file.c (build_target_list): Walk through the hask of known files
3793 and construct a list of the names of all the ones marked as
3795 * main.c (main): Initialize them to empty (and as simple variables).
3796 * doc/make.texi (Special Variables): Document them.
3797 * NEWS: Mention them.
3799 * variable.h (struct variable): Add a new flag "exportable" which
3800 is true if the variable name is valid for export.
3801 * variable.c (define_variable_in_set): Set "exportable" when a new
3802 variable is defined.
3803 (target_environment): Use the "exportable" flag instead of
3804 re-checking the name here... an efficiency improvement.
3806 2002-07-31 Paul D. Smith <psmith@gnu.org>
3808 * config.h-vms.template: Updates to build on VMS. Thanks to
3809 Brian_Benning@aksteel.com for helping verify the build.
3810 * makefile.com: Build the new hash.c file.
3811 * hash.h: Use strcpmi(), not stricmp(), in the
3812 HAVE_CASE_INSENSITIVE_FS case.
3814 2002-07-30 Paul D. Smith <psmith@gnu.org>
3816 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3817 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3818 Reported by <Brian_Benning@aksteel.com>.
3820 2002-07-10 Paul D. Smith <psmith@gnu.org>
3822 * variable.c (pop_variable_scope): Remove variable made unused by
3823 new hash infrastructure.
3824 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3825 comparisons as well as name comparisons.
3826 * variable.h: Add a prototype for new hash_init_function_table().
3827 * file.c (lookup_file): Remove variables made unused by new hash
3829 * dir.c (directory_contents_hash_2): Missing return of hash value.
3830 (dir_contents_file_exists_p): Remove variables made unused by new
3831 hash infrastructure.
3834 Installed Greg McGary's integration of the hash functions from the
3835 GNU id-utils package:
3837 2002-07-10 Greg McGary <greg@mcgary.org>
3839 * scripts/functions/filter-out: Add literals to to the
3840 pattern space in order to add complexity, and trigger
3841 use of an internal hash table. Fix documentation strings.
3842 * scripts/targets/INTERMEDIATE: Reverse order of files
3843 passed to expected `rm' command.
3845 2002-07-10 Greg McGary <greg@mcgary.org>

3937 2002-07-10 Paul D. Smith <psmith@gnu.org>
3939 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3940 prerequisite list. A real SysV make will expand the entire
3941 prerequisites list _twice_: we don't do that as it's a big
3942 backward-compatibility problem. We only replace those specific
3945 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3946 references left in the list of prerequisites. Check for .POSIX as
3947 we record targets, so we can disable non-POSIX behavior while
3948 reading makefiles as well as running them.
3949 (eval): Check the prerequisite list to see if we have anything
3950 that looks like a SysV prerequisite variable reference.
3952 2002-07-09 Paul D. Smith <psmith@gnu.org>
3954 * doc/make.texi (Prerequisite Types): Add a new section describing
3955 order-only prerequisites.
3957 * read.c (uniquize_deps): If we have the same file as both a
3958 normal and order-only prereq, get rid of the order-only prereq,
3959 since the normal one supersedes it.
3961 2002-07-08 Paul D. Smith <psmith@gnu.org>
3963 * AUTHORS: Added Greg McGary to the AUTHORS file.
3964 * NEWS: Blurbed order-only prerequisites.
3965 * file.c (print_file): Show order-only deps properly when printing
3968 * maintMakefile: Add "update" targets for wget'ing the latest
3969 versions of various external files. Taken from Makefile.maint in
3972 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3973 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3975 2002-07-07 Paul D. Smith <psmith@gnu.org>
3977 * po/*.po: Remove. We'll use wget to retrieve them at release
3980 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3981 rather than a shell you get an exception. Make sure we look up
3982 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3984 * remake.c (notice_finished_file): Fix handling of -t flag.
3985 Patch provided by Henning Makholm <henning@makholm.net>.
3987 * implicit.c (pattern_search): Some systems apparently run short
3988 of stack space, and using alloca() in this function caused an
3989 overrun. I modified it to use xmalloc() on the two variables
3990 which seemed like they might get large. Fixes Bug #476.
3992 * main.c (print_version): Update copyright notice to conform with
3994 (print_usage): Update help output.
3996 * function.c (func_eval): Create a new make function, $(eval
3997 ...). Expand the arguments, put them into a buffer, then invoke
3998 eval_buffer() on the resulting string.
3999 (func_quote): Create a new function, $(quote VARNAME). Inserts
4000 the value of the variable VARNAME without expanding it any
4003 * read.c (struct ebuffer): Change the linebuffer structure to an
4004 "eval buffer", which can be either a file or a buffer.
4005 (eval_makefile): Move the code in the old read_makefile() which
4006 located a makefile into here: create a struct ebuffer with that
4007 information. Have it invoke the new function eval() with that
4009 (eval_buffer): Create a new function that creates a struct ebuffer
4010 that holds a string buffer instead of a file. Have it invoke
4011 eval() with that ebuffer.
4012 (eval): New function that contains the guts of the old
4013 read_makefile() function: this function parses makefiles. Obtains
4014 data to parse from the provided ebuffer. Some modifications to
4015 make the flow of the function cleaner and clearer. Still could
4016 use some work here...
4017 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
4018 contents of the define/endef variable from the ebuffer.
4019 (readstring): Read the next line from a string-style ebuffer.
4020 (readline): Read the next line from an ebuffer. If it's a string
4021 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
4024 * dep.h (eval_buffer): Prototype eval_buffer();
4026 * variable.c (do_variable_definition): Make sure that all
4027 non-target-specific variables are registered in the global set.
4028 If we're invoked from an $(eval ...) we might be inside a $(call
4029 ...) or other function which has pushed a variable scope; we still
4030 want to define our variables from evaluated makefile code in the
4033 2002-07-03 Greg McGary <greg@mcgary.org>
4035 * dep.h (struct dep) [ignore_mtime]: New member.
4036 [changed]: convert to a bitfield.
4037 * implicit.c (pattern_search): Zero ignore_mtime.
4038 * main.c (main, handle_non_switch_argument): Likewise.
4039 * rule.c (convert_suffix_rule): Likewise.
4040 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
4041 (read_makefile): Parse '|' in prerequisite list.
4042 (uniquize_deps): Consider ignore_mtime when comparing deps.
4043 * remake.c (update_file_1, check_dep): Don't force remake for
4044 dependencies that have d->ignore_mtime.
4045 * commands.c (FILE_LIST_SEPARATOR): New constant.
4046 (set_file_variables): Don't include a
4047 prerequisite in $+, $^ or $? if d->ignore_mtime.
4050 2002-06-18 Paul D. Smith <psmith@gnu.org>
4052 * make.texinfo: Updates for next revision. New date/rev/etc.
4053 Recreate all Info menus. Change license on the manual to the GNU
4054 Free Documentation License. A number of typos.
4055 (Variables Simplify): Don't use "-" before it's defined.
4056 (Automatic Prerequisites): Rewrite the target example to work
4057 properly if the compile fails. Remove incorrect comments about
4058 how "set -e" behaves.
4059 (Text Functions): Move the "word", "wordlist", "words", and
4060 "firstword" functions here, from "File Name Functions".
4061 * make-stds.texi: Update from latest GNU version.
4062 * fdl.texi: (created) Import the latest GNU version.
4064 2002-06-06 Paul D. Smith <psmith@gnu.org>
4066 * variable.c (do_variable_definition): New function: extract the
4067 part of try_variable_definition() that actually sets the value
4068 into a separate function.
4069 (try_variable_definition): Call do_variable_definition() after
4070 parsing the variable definition string.
4071 (define_variable_in_set): Make the name argument const.
4073 * variable.h (enum variable_flavor): Make public.
4074 (do_variable_definition): Create prototype.
4076 * read.c (read_all_makefiles): Create a new built-in variable,
4078 (read_makefile): Add each makefile read in to this variable value.
4080 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4082 * Makefile.DOS.template: Tweak according to changes in the
4083 distribution. Add back the dependencies of *.o files.
4085 * configh.dos.template: Synchronize with config.h.in.
4087 2002-05-09 Paul D. Smith <psmith@gnu.org>
4089 * file.c (file_timestamp_now): Use K&R function declaration.
4091 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4092 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4093 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4094 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4095 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4096 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4097 nlist.n_name is a pointer rather than an array.
4099 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4100 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4101 * configure.in: Use it instead of the old version.
4103 * main.c (main): Prefer setvbuf() to setlinebuf().
4105 2002-05-08 Paul D. Smith <psmith@gnu.org>
4107 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4108 (loadavg_LDADD): Ditto.
4110 2002-04-29 Paul D. Smith <psmith@gnu.org>
4112 * expand.c (recursively_expand_for_file): Rename
4113 recursively_expand() to recursively_expand_for_file() and provide
4114 an extra argument, struct file. If the argument is provided, set
4115 the variable scope to that of the file before expanding.
4116 * variable.h (recursively_expand): Make this a macro that invokes
4117 recursively_expand_for_file() with a NULL file pointer.
4118 * variable.c (target_environment): Call the renamed function and
4119 provide the current file context.
4120 Fixes Debian bug #144306.
4122 2002-04-28 Paul D. Smith <psmith@gnu.org>
4124 Allow $(call ...) user-defined variables to be self-referencing
4125 without throwing an error. Allows implementation of transitive
4126 closures, among other possibly useful things.
4127 Requested by: Philip Guenther <guenther@sendmail.com>
4129 * variable.h (struct variable): Add a new field: exp_count, and
4130 new macros to hold its size and maximum value.
4131 (warn_undefined): Make this a macro.
4132 * variable.c (define_variable_in_set): Initialize it.
4133 * expand.c (recursively_expand): If we detect recursive expansion
4134 of a variable, check the exp_count field. If it's greater than 0
4135 allow the recursion and decrement the count.
4136 (warn_undefined): Remove this (now a macro in variable.h).
4137 * function.c (func_call): Before we expand the user-defined
4138 function, modify its exp_count field to contain the maximum
4139 number of recursive calls we'll allow. After the call, reset it
4142 2002-04-21 Paul D. Smith <psmith@gnu.org>
4144 Modified to use latest autoconf (2.53), automake (1.6.1), and
4145 gettext (0.11.1). We're using gettext's new "external" support,
4146 to avoid including libintl source with GNU make.
4148 * README.cvs: New file. Explain how to build GNU make from CVS.
4150 * configure.in: Modify checking for the system glob library.
4151 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4152 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4153 etc. will manage it correctly). Set an automake conditional
4154 USE_LOCAL_GLOB to decide whether to compile the glob library.
4156 * getloadavg.c (main): Include make.h in the "TEST" program to
4159 * Makefile.am: Remove special rules for loadavg. Replace them
4160 with Automake capabilities for building extra programs.
4162 * signame.c: This file does nothing if the system provide
4163 strsignal(). If not, it implements strsignal(). If the system
4164 doesn't define sys_siglist, then we make our own; otherwise we use
4166 * signame.h: Removed.
4168 * main.c (main): No need to invoke signame_init(). Update copyright.
4170 * ABOUT-NLS: Removed.
4171 * gettext.c: Removed.
4172 * gettext.h: Get a simplified copy from the gettext package.
4174 * i18n/*.po: Moved to po/.
4177 * config/*: Created. Contains package configuration helper files.
4178 * config.guess, config.sub: Moved to config directory.
4180 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4181 Rework to use new-style autoconf features. Use the "external"
4182 mode for gettext. Make the build.sh config file conditional on
4183 whether build.sh.in exists, to avoid autoconf errors.
4184 * acinclude.m4: Removed almost all macros as being obsolete.
4185 Rewrote remaining macros to use AC_DEFINE.
4186 * acconfig.h: Removed.
4188 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4189 conditional to handle customs support. Remove special handling
4192 2002-04-20 Paul D. Smith <psmith@gnu.org>
4194 * function.c (func_call): Don't mark the argument variables $1,
4195 etc. as recursive. They've already been fully expanded so
4196 there's no need to do it again, and doing so strips escaped $'s.
4197 Reported by Sebastian Glita <glseba@yahoo.com>.
4199 * remake.c (notice_finished_file): Walk through double-colon
4200 entries via the prev field, not the next field!
4201 Reported by Greg McGary <greg@mcgary.org>.
4203 * main.c (main): If the user specifies -q and asks for a specific
4204 target which is a makefile, we got an assert. In that case it
4205 turns out we should continue normally instead.
4207 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4209 * i18n/he.po: Installed a new translation.
4211 2002-01-07 Paul D. Smith <psmith@gnu.org>
4213 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4215 2001-12-04 Paul D. Smith <psmith@gnu.org>
4217 * i18n/ja.po: Installed an updated translation.
4219 2001-09-06 Paul Eggert <eggert@twinsun.com>
4221 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4222 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4224 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4226 (main): Get rid of any avoidable limit on stack size.
4228 2001-09-04 Paul D. Smith <psmith@gnu.org>
4230 * i18n/da.po: Installed an updated translation.
4232 2001-08-03 Paul D. Smith <psmith@gnu.org>
4234 * i18n/fr.po: Installed an updated translation.
4235 Resolves Debian bug #106720.
4237 2001-06-13 Paul D. Smith <psmith@gnu.org>
4239 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4242 2001-06-11 Paul D. Smith <psmith@gnu.org>
4244 * i18n/ko.po: Installed a new translation.
4246 2001-05-06 Paul D. Smith <psmith@gnu.org>
4248 Modify the EINTR handling.
4250 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4251 the way in which we manage the file descriptor/signal handler race
4252 trap to be more efficient.
4254 2001-05-06 Paul Eggert <eggert@twinsun.com>
4256 Restart almost all system calls that are interrupted, instead
4257 of worrying about EINTR. The lone exception is the read() for
4260 * configure.in (HAVE_SA_RESTART): New macro.
4261 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4262 * main.c (main): Use SA_RESTART instead of the old,
4263 nonstandard SA_INTERRUPT.
4265 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4266 * main.c (bsd_signal): New function or macro,
4267 if the implementation doesn't supply it.
4268 (The bsd_signal function will be in POSIX 1003.1-200x.)
4269 (HANDLESIG): Remove.
4270 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4272 * make.h (EINTR_SET): Remove.
4273 (SA_RESTART): New macro.
4275 * arscan.c (ar_member_touch): Don't worry about EINTR.
4276 * function.c (func_shell): Likewise.
4277 * job.c (reap_children, free_child, new_job): Likewise.
4278 * main.c (main): Likewise.
4279 * remake.c (touch_file, name_mtime): Likewise.
4281 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4282 if fstat failed with errno!=EINTR, the error was ignored.
4284 * job.c (set_child_handler_action_flags): New function.
4285 (new_job): Use it to temporarily clear the SIGCHLD action flags
4286 while reading the token.
4288 2001-05-02 Paul D. Smith <psmith@gnu.org>
4290 * job.c (start_job_command): Don't add define/endef per-line flags
4291 to the top-level flags setting.
4293 2001-04-03 Paul D. Smith <psmith@gnu.org>
4295 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4296 bit on error, so check for odd return values, not non-0 return
4298 (VMS_get_member_info): Calculate the timezone differences correctly.
4299 Reported by John Fowler <jfowler@nyx.net>.
4302 2001-03-14 Paul D. Smith <psmith@gnu.org>
4304 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4305 value before invoking define_variable().
4306 Reported by John Fowler <jfowler@nyx.net>.
4308 2001-02-07 Paul D. Smith <psmith@gnu.org>
4310 * read.c (record_target_var): If we reset the variable due to a
4311 command-line variable setting overriding it, turn off the "append"
4314 2001-01-17 Paul D. Smith <psmith@gnu.org>
4316 * variable.c (lookup_variable) [VMS]: When getting values from the
4317 environment, allocate enough space for the _value_ plus escapes,
4318 not enough space for the name plus escapes :-/.
4319 Reported by John Fowler <jfowler@nyx.net>.
4321 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4322 warnings that make generates, so it doesn't look like an error.
4323 Reported by Karl Berry <karl@gnu.org>.
4326 Fix for PR/2020: Rework appended target-specific variables. I'm
4327 fairly confident this algorithm is finally correct.
4329 * expand.c (allocated_variable_append): Rewrite. Instead of
4330 expanding each appended variable then adding all the expanded
4331 strings together, we append all the unexpanded values going up
4332 through the variable set contexts, then expand the final result.
4333 This behaves just like non-target-specific appended variable
4334 values, while the old way didn't in various corner cases.
4335 (variable_append): New function: recursively append the unexpanded
4336 value of a variable, walking from the outermost variable scope to
4338 * variable.c (lookup_variable): Remove the code that looked up the
4339 variable set list if the found variable was "append". We don't
4341 (lookup_variable_in_set): Make this non-static so we can use it
4343 (try_variable_definition): Use lookup_variable_in_set() rather
4344 than faking out current_variable_set_list by hand (cleanup).
4345 * variable.h: Add a prototype for the now non-static
4346 lookup_variable_in_set().
4348 2000-11-17 Paul D. Smith <psmith@gnu.org>
4350 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4351 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4352 before throwing a fit.
4354 2000-11-17 Paul D. Smith <psmith@gnu.org>
4356 * read.c (readline): CRLF calculations had a hole, if you hit the
4357 buffer grow scenario just right. Reworked the algorithm to avoid
4358 the need for len or lastlen at all. Problem description with
4359 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4361 2000-10-24 Paul D. Smith <psmith@gnu.org>
4363 * gettext.c (SWAP): Declare this with the prototype, otherwise
4364 some systems don't work (non-32-bit? Reported for Cray T3E).
4365 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4367 2000-10-05 Paul D. Smith <psmith@gnu.org>
4369 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4370 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4372 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4374 2000-09-22 Paul D. Smith <psmith@gnu.org>
4376 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4377 parts of the real gettext.h here, and we expect to really include
4378 the real gettext.h later. If we keep this #define, it's ignored.
4380 2000-09-21 Paul D. Smith <psmith@gnu.org>
4382 * main.c (log_working_directory): Rework the text to use complete
4383 sentences, to make life simpler for the translators.
4385 2000-08-29 Paul D. Smith <psmith@gnu.org>
4387 * file.c (remove_intermediates): Print a debug message before we
4388 remove intermediate files, so the user (if she uses -d) knows
4391 2000-08-21 Paul D. Smith <psmith@gnu.org>
4393 * variable.c (try_variable_definition): Change how we handle
4394 target-specific append variable defns: instead of just setting the
4395 value, expand it as an append _but_ only within the current
4396 target's context. Otherwise we lose all but the last value if the
4397 variable is appended more than once within the current target
4398 context. Fixes PR/1831.
4400 2000-08-16 Paul D. Smith <psmith@gnu.org>
4402 * function.c (func_shell): Nul-terminate the buffer before
4403 printing an exec error message (just in case it's not!).
4404 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4406 2000-07-25 Paul D. Smith <psmith@gnu.org>
4408 * job.c (construct_command_argv_internal): Add "~" to the list of
4409 sh_chars[] which disallow optimizing out the shell call.
4411 2000-07-23 Paul Eggert <eggert@twinsun.com>
4413 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4414 supersedes --disable-nsec-timestamps.
4415 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4416 * README: Remove --disable-nsec-timestamps.
4418 * filedef.h (struct file.low_resolution_time): New member.
4419 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4420 * remake.c (update_file_1):
4421 Avoid spurious rebuilds due to low resolution time stamps,
4422 generalizing the earlier code that applied only to archive members.
4423 (f_mtime): Archive members always have low resolution time stamps.
4425 * configure.in: Remove --disable-nsec-timestamps, as this has
4426 been superseded by .LOW_RESOLUTION_TIME.
4428 2000-07-23 Paul Eggert <eggert@twinsun.com>
4430 * configure.in (enable_nsec_timestamps): Renamed from
4431 make_cv_nsec_timestamps, since enable/disable options
4432 shouldn't be cached.
4434 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4435 and Paul Eggert <eggert@twinsun.com>
4437 * file.c (file_timestamp_now):
4438 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4439 so that clock_gettime is not linked unless needed.
4441 * filedef.h (FILE_TIMESTAMP_HI_RES):
4442 Remove definition; "configure" now does this.
4444 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4445 to before high resolution file timestamp check,
4446 since that check now uses uintmax_t.
4447 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4448 high resolution file timestamps.
4449 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4450 so that we don't link in clock_gettime unnecessarily.
4452 2000-07-17 Paul D. Smith <psmith@gnu.org>
4454 * i18n/ja.po: New version of the translation file.
4456 2000-07-07 Paul D. Smith <psmith@gnu.org>
4458 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4459 the offset calculation.
4460 (name_mtime): Replace EINTR test with EINTR_SET macro.
4462 2000-07-07 Paul Eggert <eggert@twinsun.com>
4466 * remake.c (update_file_1):
4467 Avoid spurious rebuilds of archive members due to their
4468 timestamp resolution being only one second.
4469 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4470 the clock's resolution being lower than file timestamps'.
4471 When warning about future timestamps, report only the discrepancy,
4472 not the absolute value of the timestamp and the current time.
4474 * file.c (file_timestamp_now): New arg RESOLUTION.
4475 * filedef.h (file_timestamp_now): Likewise.
4476 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4478 2000-07-05 Paul D. Smith <psmith@gnu.org>
4480 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4481 to listp. Fixes PR/1793.
4483 2000-06-26 Paul Eggert <eggert@twinsun.com>
4485 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4487 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4489 * remake.c (f_mtime): Remove unused var memtime.
4491 2000-06-25 Martin Buchholz <martin@xemacs.org>
4493 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4494 Ran spell-check on make.texinfo.
4496 2000-06-23 Paul D. Smith <psmith@gnu.org>
4498 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4499 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4500 * make.h: Define these macros.
4502 * Version 3.79.1 released.
4504 * configure.in: Add a new option, --disable-nsec-timestamps, to
4505 avoid using sub-second timestamps on systems that support it. It
4506 can lead to problems, e.g. if your makefile relies on "cp -p".
4507 * README.template: Document the issue with "cp -p".
4509 * config.guess, config.sub: Updated.
