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

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

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

827 2009-10-03 Paul Smith <psmith@gnu.org>
829 * make.h: Include <alloca.h> even on systems where __GNUC__ is

889 double-colons have a different meaning. Savannah bug #27497.
891 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
893 * configh.dos.template: Remove unconditional definition of
894 SYS_SIGLIST_DECLARED.
895 Include <sys/version.h> because ports of GCC 4.3.0 and later no
896 longer include it, so macros like __DJGPP_MINOR__ are no longer
897 defined automatically.
899 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
900 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
901 instead of using the hardcoded ones.
902 (SUBDIRS): doc subdir added.
903 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
904 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
905 create html formated docs. texi2html may not be ported to DOS.
906 (make.info, make.dvi, make.ps, make.html): Make targets depend on
908 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
909 -I switch to look in ./ instead of ./doc.
910 (html): Target depend on html-recursive instead of make_1.html.
911 (make_1.html): Removed.
912 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.

915 (mostlyclean-recursive, clean-recursive, distclean-recursive)
916 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
917 (tags-recursive): Allow for more than one subdir in the build
919 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
920 targets. Enter into doc/ to produce the targets.
921 (all-am): $(INFO_DEPS) replaced by info.
923 2009-09-26 Paul Smith <psmith@gnu.org>
925 * read.c (record_files): Use free_ns() to free struct nameseq.
928 * rule.c (freerule): Use free_dep_chain().
930 * read.c (record_files): Free FILENAMES chain for implicit rules.
931 (eval): Static pattern targets go into the string cache.
933 * function.c (string_glob): Free NAME in the nameseq chain.
935 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
937 * implicit.c (pattern_search): Terminate early if we haven't
938 found any rules to try (performance improvement).
940 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
942 * implicit.c (pattern_search): Merge three parallel arrays,
943 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
944 of struct TRYRULE. In the old version the latter two arrays
945 had insufficient length.
947 2009-09-24 Paul Smith <psmith@gnu.org>
949 * implicit.c (pattern_search): Add back support for order-only
950 prerequisites for secondary expansion implicit rules, that were
951 accidentally dropped. If we find a "|", enable order-only mode
952 and set IGNORE_MTIME on all deps that are seen afterward.
953 (pattern_search): Fix memory leaks: for intermediate files where
954 we've already set the file variable and pattern variable sets, be
955 sure to either save or free them as appropriate.
957 2009-09-23 Paul Smith <psmith@gnu.org>
959 Rework the way secondary expansion is stored, for efficiency.
960 This changes secondary expansion so that ONLY WHEN we know we have
961 a possibility of needing secondary expansion, do we defer the
962 secondary expansion. This means more parsing the deps but we use
963 a lot less memory (due to the strcache). Also, this fixes
966 * read.c (eval): Don't parse the dep string here anymore.
967 (record_files): Take the dep argument as an unparsed string. If
968 secondary expansion is enabled AND the prereq string has a '$' in
969 it, then set NEED_2ND_EXPANSION and keep the entire string.
970 Otherwise, parse the dep string here to construct the dep list
971 with the names in the strcache.
973 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
974 duplicate the name string (others are in the strcache).
976 * implicit.c: Remove struct idep and free_idep_chain(): unused.
977 (struct patdeps): New structure to store prereq information.
978 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
979 which prerequisites need expansion, and expand only those.
981 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
982 and enter_prereqs(). split_prereqs() takes a fully-expanded string
983 and splits it into a DEP list, handling order-only prereqs.
984 (enter_prereqs): This function enters a list of DEPs into the file
985 database. If there's a stem defined, expand any pattern chars.
986 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
987 set. Use the above functions.
988 (snap_deps): Only perform second expansion on prereqs that need it,
989 as defined by the NEED_2ND_EXPANSION flag.
990 (print_prereqs): New function to print the prereqs
991 (print_file): Call print_prereqs() rather than print inline.
993 * hash.h (STRING_COMPARE): Take advantage of strcache() by
995 (STRING_N_COMPARE): Ditto.
996 (ISTRING_COMPARE): Ditto.
998 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
999 (parse_file_seq): Return void*
1000 * read.c (parse_file_seq): Return void*.
1001 (eval): Invoke macroized version of parse_file_seq()
1002 * default.c (set_default_suffixes): Ditto.
1003 * file.c (split_prereqs): Ditto.
1004 * function.c (string_glob): Ditto.
1005 * main.c (main): Ditto.
1006 * rule.c (install_pattern_rule): Ditto.
1008 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
1010 2009-09-16 Paul Smith <psmith@gnu.org>
1012 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
1014 * dep.h: Create alloc_dep() / free_dep() macros.
1016 * implicit.c (pattern_search): Take advantage of the new
1017 parse_file_seq() to add the directory prefix to each prereq.
1019 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
1020 all. Avoid reversing chains. Support adding prefixes.
1021 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
1022 cached/non-cached results.
1023 (eval): Remove multi_glob() & invoke new parse_file_seq().
1024 * rule.c (install_pattern_rule): Ditto.
1025 * main.c (main): Ditto.
1026 * implicit.c (pattern_search): Ditto.
1027 * function.c (string_glob): Ditto.
1028 * file.c (parse_prereqs): Ditto.
1029 * default.c (set_default_suffixes): Ditto.
1031 * variable.c (parse_variable_definition): Don't run off the end of
1032 the string if it ends in whitespace (found with valgrind).
1034 * commands.c (set_file_variables): Keep space for all targets in
1035 $? if -B is given (found with valgrind).
1037 2009-09-15 Paul Smith <psmith@gnu.org>
1039 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
1040 (xcalloc): Add new function.
1041 * make.h: New declarations.
1043 * ar.c (ar_glob_match): New calling method for concat().
1044 * main.c (main): Ditto.

1046 * read.c (eval_makefile): Ditto.
1047 (tilde_expand): Ditto.

1049 * variable.c (target_environment): Ditto.
1050 (sync_Path_environment): Ditto.
1052 * ar.c (ar_glob_match): Use xcalloc().
1053 * dir.c (file_impossible): Ditto.
1054 * file.c (enter_file): Ditto.
1055 * job.c (new_job): Ditto.
1056 * read.c (parse_file_seq): Ditto.
1057 * vmsfunctions.c (opendir): Ditto.
1059 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
1061 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
1062 inside the loop that looks up environment for PATH.

1067 sync_Path_environment.
1069 2009-08-02 Paul Smith <psmith@gnu.org>
1071 * remake.c (notice_finished_file): Ensure file->cmds is not null
1072 before looping through them. Fixes Savannah bug #21824.
1074 * doc/make.texi (Wildcard Examples): Clarify when objects is
1075 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1076 (Include): Clarify the behavior of -include.
1077 Fixes Savannah bug #18963.
1079 2009-08-01 Paul Smith <psmith@gnu.org>
1081 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1082 etc. come on the command line. Fixes Savannah bug #27093.
1084 * expand.c (expand_argument): If the argument is large enough use
1085 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1087 * variable.c (do_variable_definition): Avoid using alloca() to
1088 hold values, which can be large. Fixes Savannah bug #23960.
1090 * job.c (new_job): Use memmove() instead of strcpy() since both
1091 pointers are in the same memory block. Fixes Savannah bug #27148.
1092 Patch by Petr Machata.
1094 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1096 * job.c (construct_command_argv_internal): Add "ulimit" and
1097 "unset" to the sh_cmds for Unixy shells.
1099 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1101 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1102 that set make_cv_sys_gnu_glob, so they are also correctly set
1103 when the cache has been populated before.
1105 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1107 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1108 exist, as realpath(3) does where it's supported.
1110 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1112 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1113 (abspath): Support systems that define HAVE_DOS_PATHS (have
1114 drive letters in their file names). Use IS_PATHSEP instead of a
1115 literal '/' comparison. Fixes Savannah bug #26886.
1117 2009-06-14 Paul Smith <psmith@gnu.org>
1119 * remake.c (update_file_1): Remember the original file we marked
1120 as updating, so we can clear that flag again. If we find a target
1121 via vpath, FILE might change.
1122 (check_dep): Ditto. Fixes Savannah bug #13529.
1123 Patch by Reid Madsen <reid.madsen@tek.com>.
1125 2009-06-13 Paul Smith <psmith@gnu.org>
1127 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1128 included by MAKEFILES cannot give default goals.
1129 * read.c (eval): If set_default is not set, pass the no-default-goal
1130 value when we read included makefiles. Fixes Savannah bug #13401.
1132 * ar.c (ar_name): Ensure that targets with empty parens aren't
1133 considered archive member references: archive members must have a
1134 non-empty "member" string. Fixes Savannah bug #18435.
1136 * function.c (string_glob): Rely on multi_glob() to determine
1137 whether files exist or not. Remove call to file_exists_p() which
1138 is not always correct. Fixes Savannah bug #21231.
1139 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1140 then only files that really exist will be returned.
1141 * dep.h: Add new argument to multi_glob().
1142 * rule.c (install_pattern_rule): Ditto.
1143 * read.c (eval): Ditto.
1144 * main.c (main): Ditto.
1145 * implicit.c (pattern_search): Ditto.
1146 * file.c (parse_prereqs): Ditto.
1147 * default.c (set_default_suffixes): Ditto.
1149 2009-06-09 Paul Smith <psmith@gnu.org>
1151 * commands.c (set_file_variables): If always_make_flag is set,
1152 always add the prereq to $?. Fixes Savannah bug #17825.
1154 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1155 to rebuild the deps of all the also_make targets for that file.
1156 Fixes Savannah bug #19108.
1158 * implicit.c (pattern_search): Undo test for is_target, added by
1159 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1160 Rule Search Algorithm". Fixes Savannah bug #17752.
1162 * main.c (clean_jobserver): Clear the jobserver_fds options and
1163 set job_slots to the default when we clean up.
1164 (define_makeflags): Return the new MAKEFLAGS value.
1165 (main): Reset MAKEFLAGS in the environment when we re-exec.
1166 Fixes Savannah bug #18124.
1168 2009-06-08 Paul Smith <psmith@gnu.org>
1170 * read.c (eval): Collapse continuations post-semicolon on target-
1171 specific variables. Fixes Savannah bug #17521.
1173 2009-06-07 Paul Smith <psmith@gnu.org>
1175 * job.c (reap_children): For older systems without waitpid() (are
1176 there any of these left?) run wait(2) inside EINTRLOOP to handle
1177 EINTR errors. Fixes Savannah bug #16401.
1179 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1181 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1183 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1184 not the end, to catch second expansion $(eval ...) defining new
1185 target/prereq relationships during snap_deps.
1186 Fixes Savannah bug #24622.
1188 * read.c (record_files): The second-expansion "f->updating" hack
1189 was not completely correct: if assumed that the target with
1190 commands always had prerequisites; if one didn't then the ordering
1191 was messed up. Fixed for now to use f->updating to decide whether
1192 to preserve the last element in the deps list... but this whole
1193 area of constructing and reversing the deps list is too confusing
1194 and needs to be reworked. Fixes Savannah bug #21198.
1196 2009-06-06 Paul Smith <psmith@gnu.org>
1198 * hash.c (hash_insert): Remove useless test for NULL.
1199 Fixes Savannah bug #21823.
1201 * make.h: Move SET_STACK_SIZE determination to make.h.
1202 * main.c (main): New global variable, STACK_LIMIT, holds the
1203 original stack limit when make was started.
1204 * job.c (start_job_command): Reset the stack limit, if we changed it.
1205 Fixes Savannah bug #22010.
1207 * remake.c (check_dep): Only set the target's state to not-started
1208 if it's not already running. Found this while testing -j10 builds
1209 of glibc: various targets were being rebuilt multiple times.
1210 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1213 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1214 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1217 2009-06-04 Paul Smith <psmith@gnu.org>
1219 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1221 * maintMakefile: Modify access of config and gnulib Savannah
1222 modules to use GIT instead of CVS.
1224 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1225 Fixes Savannah bug #24655.
1227 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1228 this can happen during some invocations of $(eval ...) for example.
1229 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1231 2009-06-02 Paul Smith <psmith@gnu.org>
1233 * configure.in: Check for fileno()
1234 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1235 for the makefile file so invocations of $(shell ...) don't inherit it.
1236 Fixes Savannah bug #24277.
1238 2009-06-01 Paul Smith <psmith@gnu.org>
1240 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1241 expansion was handled incorrectly. Rework the default goal
1242 handling to save the variable only. Remove default_goal_file and
1244 * read.c (eval): Check default_goal_var, not default_goal_name.
1245 * read.c (record_target_var): Don't check default_goal_file here.
1247 2009-05-31 Paul Smith <psmith@gnu.org>
1249 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1250 it, and if the multi_glob() returns nothing (say it expanded to
1251 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1253 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1254 $(and ..) to the reference. Fixes Savannah bug #25694.
1256 * make.1: Be clear that some recipes will be executed even with -n.
1257 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1259 * doc/make.texi (Override Directive): Make more clear how
1260 overrides and appends interact.
1261 Elucidates part of Savannah bug #26207.
1263 * read.c (record_target_var): Don't reset the origin on
1264 target-specific variables; try_variable_definition() will handle
1265 this correctly. Fixes Savannah bug #26207.
1267 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1268 Fixes Savannah bug #25712.
1270 * implicit.c (pattern_search): Keep a pointer to the beginning of
1271 the filename and save that instead of the constructed pointer.
1272 Fixes Savannah bug #26593.
1273 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1275 2009-05-30 Paul Smith <psmith@gnu.org>
1277 * doc/make.texi (Multi-Line): Add a description of the new abilities
1278 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1279 "command sequence" vs. "recipe" syntax.
1280 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1281 after a define, to create variables with those flavors.
1283 2009-05-25 Paul Smith <psmith@gnu.org>
1285 Reworked the parser for variable assignments to allow multiple
1286 modifiers, and in any order. Also allows variable and
1287 prerequisites to be modifier names ('export', 'private', etc.)
1289 * NEWS: Add notes about user-visible changes.
1291 * read.c (struct vmodifiers): Remember what modifiers were seen.
1292 (parse_var_assignment): New function to parse variable assignments.
1293 (eval): Call the new function. Handle variable assignments earlier.
1295 * variable.c (parse_variable_definition): Only parse; don't create var.
1296 (assign_variable_definition): Call parse, then create the var.
1298 2009-05-24 Paul Smith <psmith@gnu.org>
1300 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1301 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1303 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1305 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1306 Fixes Savannah bug #25412.
1308 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1309 prototype for xmalloc.
1310 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1311 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1312 Loop over an array of extensions, instead of duplicating the same
1313 code inline. Use SearchPath followed by CreateFile, instead of
1314 the obsolete OpenFile. Fixes Savannah bug #17277.
1315 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1316 to `find_file'. Fixes Savannah bug #25662.
1318 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1320 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1321 Fixes Savannah bug #20495.
1323 2009-02-28 Ralf Wildenhues <address@hidden>
1325 * doc/make.texi (Instead of Execution): Document interaction of
1326 -t with phony targets.
1328 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1330 Introduce a new keyword "private" which applies to target-specific
1331 variables and prevents their values from being inherited.
1333 * variable.h (struct variable): Add private_var flag to each variable.
1334 Add a flag to specify which list entry switches to the parent target.
1335 * variable.c (define_variable_in_set): Initialize private_var flag.
1336 (lookup_variable): Skip private variables in parent contexts.

1348 * make.h: Rename savestring to xstrndup.
1349 * commands.c (chop_commands): Ditto.
1350 * function.c (func_foreach): Ditto.
1351 * read.c (eval, record_files): Ditto.
1352 * variable.c (define_variable_in_set): Ditto.
1354 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1356 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1359 * w32/subproc/build.bat (GCCBuild): Likewise.
1361 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1363 * job.c (construct_command_argv_internal): Avoid extra backslash
1364 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1367 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1369 * README.W32.template: Remove obsolete text about non-support for
1370 -jN without Unixy shell. Remove obsolete text about not supplying
1371 Visual Studio project files (we do supply them). Modify text to
1372 prefer GCC builds to MSC builds.
1374 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1376 * doc/make.texi (Empty Targets): Fix typo.

1388 2008-01-26 Eli Zaretskii <eliz@gnu.org>
1390 * variable.c (target_environment): Don't use shell_var if its
1391 `value' field is NULL.
1393 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1395 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1397 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1398 (TEXINFOS): Value changed to `doc/make.texi'.
1399 (.SUFFIXES): Use .texi instead of .texinfo.
1400 (make.info, make.dvi): Depend on doc/make.texi.
1401 (.texi.info): New target, instead of ".texinfo.info". Change -I
1402 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1403 (.texi): New target, instead of ".texinfo". Change -I switch to
1404 $(MAKEINFO) to look in doc/. Use --no-split.
1405 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1406 switch to $(MAKEINFO) to look in doc/.
1407 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1408 "*.i[0-9][0-9]" (due to --no-split above).
1409 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1410 (html, make_1.html): New targets.
1411 (.PHONY): Add "html".

1417 HAVE_DECL_SYS_SIGLIST.
1419 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1420 build does not use child_execute_job.
1422 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1423 export the SHELL environment variable to the child.
1425 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1427 * config.h.W32: Include sys/types.h.

1444 * remake.c (f_mtime): Print time difference values between 100 and
1445 ULONG_MAX in fixed-point notation rather than in exponention notation.
1447 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1449 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1450 a more complex value than a simple shell: if it's not a default
1451 shell now then expand it and see if is a default shell then.
1453 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1455 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1456 pathnames, with const strings.
1457 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1458 from the template (used for building from CVS, not a dist).
1460 2007-10-10 Paul Smith <psmith@gnu.org>
1462 * make.h: Add a prototype for w32_kill() (change suggested by
1463 Yongwei Wu <wuyongwei@gmail.com>).
1465 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1467 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1468 directories in Path.
1470 2007-09-12 Paul Smith <psmith@gnu.org>

1473 Provided by Diego Biurrun <diego@biurrun.de>
1474 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1475 Provided by Diego Biurrun <diego@biurrun.de>
1477 2007-09-11 Paul Smith <psmith@gnu.org>
1479 * doc/make.texi (Special Variables): Moved this into the "How to
1480 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1481 (MAKEFILE_LIST) No longer a section; this was added into the
1482 "Special Variables" section.
1483 (Rule Introduction): Reference .RECIPEPREFIX.
1484 (Simple Makefile): Ditto.
1485 (Rule Syntax): Ditto.
1486 (Command Syntax): Ditto.
1487 (Error Messages): Ditto.
1489 2007-09-10 Paul Smith <psmith@gnu.org>
1491 * commands.c (print_commands): Don't print an extra line in the
1492 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1494 * read.c (construct_include_path): Add the full string to the cache; we
1495 were chopping the last char.
1497 * NEWS: Announce the .RECIPEPREFIX special variable.
1498 * variable.c (lookup_special_var): Rename from handle_special_var().
1499 (lookup_variable): Call the new name.
1500 (set_special_var): New function: handle setting of special variables.
1501 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1502 (do_variable_definition): Call it.
1503 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1504 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1505 * main.c (main): Create the .RECIPEPREFIX special variable.
1506 * read.c (eval): Remove the cmd_prefix characters from the command
1507 scripts here, so they're not stored in the commands array at all,
1508 rather than waiting and stripping them out during command construction.
1509 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1511 2007-08-15 Paul Smith <psmith@gnu.org>
1513 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1514 file has had the section info removed, so add some to make.texi
1515 before we include it.
1517 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1519 * remake.c (check_dep): Reset the target state for intermediate
1520 files. They might have been considered before but not updated
1521 then (order-only for example) but they will be this time.
1522 Fixes Savannah bug #'s 3330 and 15919.
1524 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1526 Fix Savannah bug #20549:
1527 * function.c (func_shell): Call construct_command_argv with zero
1529 * job.c (construct_command_argv_internal): New argument FLAGS; all
1531 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1533 * job.h (construct_command_argv_internal): Update prototype.
1535 2007-07-13 Paul Smith <psmith@gnu.org>
1537 * file.c (expand_deps): Use variable_buffer as the start of the
1538 buffer, not the original pointer (in case it was reallocated).
1539 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1540 Fixes Savannah bug #20452.
1542 2007-07-04 Paul Smith <psmith@gnu.org>
1544 * (ALL FILES): Update to GPLv3.

1551 * maintMakefile: Update Translation Project location.
1553 2007-06-13 Paul Smith <psmith@gnu.org>
1555 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1556 "Expansion of a deferred"
1557 Fixes Savannah bug #20018.

1560 reading_file rather than setting it to 0 at the end.
1561 Fixes Savannah bug #20033.
1563 2007-05-11 Paul Smith <psmith@gnu.org>
1565 * job.c (new_job): Add debug info to specify where make found the
1566 command script it is running to build a target.
1567 Fixes Savannah bug #18617.
1569 * default.c (default_suffixes,default_suffix_rules,default_variables):
1570 Add support for Objective C. Fixes Savannah bug #16389.
1571 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.

1577 Dave Korn <dave.korn@artimi.com>
1579 2007-05-08 Paul Smith <psmith@gnu.org>
1581 Fix Savannah bug #19656:
1583 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1585 * make.h: Change all case-insensitive string compares to use
1586 strcasecmp() (from POSIX). If we don't have that but do have one
1587 of the others, define strcasecmp to be one of those instead. If
1588 we don't have any, declare a prototype for our own version.
1590 * misc.c (strcasecmp): Use this if we can't find any native
1591 case-insensitive string comparison function.
1592 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1593 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1595 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1596 strcasecmp() instead of stricmp().
1597 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1598 instead of strcmpi().
1599 * acinclude.m4: Remove the strcasecmp() check from here.
1601 2007-03-21 Paul Smith <psmith@gnu.org>
1603 * configure.in: Don't turn on case-insensitive file system support
1604 if --disable-... is given. Fixes Savannah bug #19348.
1606 2007-03-19 Paul Smith <psmith@gnu.org>
1608 * ALL: Use the strcache for all file name strings, or other
1609 strings which we will never free. The goal is to save memory by
1610 avoiding duplicate copies of strings. However, at the moment this
1611 doesn't save much memory in most situations: due to secondary
1612 expansion we actually save prerequisite lists twice (once before
1613 the secondary expansion, and then again after it's been parsed
1614 into individual file names in the dep list). We will resolve this
1615 in a future change, by doing the parsing up-front for targets
1616 where secondary expansion is not set.
1618 Moving things into the strcache also allows us to use const
1619 pointers in many more places.
1621 2007-01-03 Paul Smith <psmith@gnu.org>
1623 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1624 the function, not just the first. Fixes Savannah bug #18680.
1626 2006-11-18 Paul Smith <psmith@gnu.org>
1628 * strcache.c (strcache_add_len): Don't allocate a new buffer
1629 unless the string is not already nil-terminated. Technically this
1630 is a violation of the standard, since we may be passed an array
1631 that is not long enough to test one past. However, in make this
1632 is never true since we only use nil-terminated strings or
1633 sub-strings thereof.
1635 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1637 * main.c: New global cmd_prefix, defaults to '\t'.
1638 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1641 * dir.c: Constified.
1642 (dir_contents_file_exists_p): Check for an error return from
1643 readdir(), just in case.
1645 * commands.c: Constified.
1646 * default.c: Constified.
1647 * expand.c: Constified.
1648 * function.c: Partial constification.

1653 * w32/pathstuff.c: Partial constification.
1655 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1657 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1658 backslashes and drive letters as absolute.
1660 2006-10-22 Paul Smith <psmith@gnu.org>

1664 2006-10-21 Paul Smith <psmith@gnu.org>
1667 * arscan.c: Constified.
1669 2006-09-30 Paul Smith <psmith@gnu.org>
1671 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1672 point to lastword since the example was updated.
1673 Fixes Savannah bug #16304.
1674 (Secondary Expansion): Correct example description.
1675 Fixes Savannah bug #16468.
1676 (Makefile Contents): Clarify that comments cannot appear within
1677 variable references or function calls.
1678 Fixes Savannah bug #16577.
1679 (Special Targets): Clarify how .NOTPARALLEL works in recursion.

1683 prerequisites. Fixes Savannah bug #17880.
1684 (Rule Syntax): "lise" -> "list"
1685 (Multiple Rules): ... -> @dots{}
1686 (Splitting Lines): ditto.
1688 * remake.c (update_file_1): Prereqs that don't exist should be
1689 considered changed, for the purposes of $?.
1690 Fixes Savannah bug #16051.

1732 that don't have extended grep.
1733 (cvsclean): Use $(PERL) instead of perl.

1737 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1739 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1740 inner-scope variables don't mask outer-scope variables.

1801 Declare and define sh_chars_sh[].
1803 2006-03-23 Paul D. Smith <psmith@gnu.org>
1805 * configure.in: Look for build.sh.in in $srcdir so it will be
1806 built for remote configurations as well.
1808 * Makefile.am: Make sure to clean up build.sh during distclean.
1809 Fixes Savannah bug #16166.
1811 * misc.c (log_access): Takes a const char *.

1813 Both fixes for Savannah bug #16170.
1815 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1817 * implicit.c (pattern_search): Call set_file_variables only
1818 if we have prerequisites that need second expansion. Fixes
1819 Savannah bug #16140.
1821 2006-03-19 Paul D. Smith <psmith@gnu.org>
1823 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1824 memory on hosts that don't support it directly.

1827 make sure I don't forget any).
1829 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1831 (die): Cleanup code was removed from here; call the new function.
1832 (main): If we are re-execing, clean up the jobserver first so we
1833 don't leak file descriptors.

1839 allow multiple concurrent runs.
1840 Patch from Joseph Myers <joseph@codesourcery.com>
1842 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1844 * dep.h (struct dep): Add the stem field.
1845 * misc.c (alloc_dep, free_dep): New functions.
1846 (copy_dep_chain): Copy stem.
1847 (free_dep_chain): Use free_dep.
1848 * read.c (record_files): Store stem in the dependency line.
1849 * file.c (expand_deps): Use stem stored in the dependency line. Use
1850 free_dep_chain instead of free_ns_chain.
1851 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1852 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.

1860 expanding the result, we expand (or not, if it's simple) each part
1862 (allocated_variable_append): Don't expand the final result.
1863 Fixes Savannah bug #15913.
1865 2006-03-09 Paul Smith <psmith@gnu.org>
1867 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1868 listed non-existent files as changed. Turns out there's a bug in
1869 the Linux kernel builds which means that this change causes
1870 everything to rebuild every time. We will re-introduce this fix
1871 in the next release, to give them time to fix their build system.
1872 Fixes Savannah bug #16002.
1873 Introduces Savannah bug #16051.
1875 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1888 to be null; don't core in that case.
1890 2006-02-19 Paul D. Smith <psmith@gnu.org>
1892 * commands.c (set_file_variables): Realloc, not malloc, the static
1893 string values to avoid memory leaks.
1895 * expand.c (recursively_expand_for_file): Only set reading_file to
1896 an initialized value.
1898 * implicit.c (pattern_search): We need to make a copy of the stem
1899 if we get it from an intermediate dep, since those get freed.
1901 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1903 (enter_file) [VMS]: Ditto.
1904 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

1908 * job.c (construct_command_argv_internal): Fix last change.
1910 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1911 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1912 the calls to _beginthreadex.
1914 * expand.c (recursively_expand_for_file): Initialize `save' to
1915 prevent compiler warnings.
1917 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1919 * job.c (construct_command_argv_internal): Don't create a temporary
1920 script/batch file if we are under -n. Call _setmode to switch the
1921 script file stream to text mode.
1923 2006-02-17 Paul D. Smith <psmith@gnu.org>
1925 * variable.c (merge_variable_set_lists): Don't try to merge the
1926 global_setlist. Not only is this useless, but it can lead to
1927 circularities in the linked list, if global_setlist->next in one
1928 list gets set to point to another list which also ends in
1930 Fixes Savannah bug #15757.
1932 2006-02-15 Paul D. Smith <psmith@gnu.org>
1934 Fix for Savannah bug #106.
1936 * expand.c (expanding_var): Keep track of which variable we're
1937 expanding. If no variable is being expanded, it's the same as
1939 * make.h (expanding_var): Declare it.
1940 * expand.c (recursively_expand_for_file): Set expanding_var to the
1941 current variable we're expanding, unless there's no file info in
1942 it (could happen if it comes from the command line or a default
1943 variable). Restore it before we exit.
1944 * expand.c (variable_expand_string): Use the expanding_var file
1945 info instead of the reading_file info.

1955 * read.c (eval): Even if the included filenames expands to the
1956 empty string we still need to free the allocated buffer.
1958 * implicit.c (pattern_search): If we allocated a variable set for
1959 an impossible file, free it.
1960 * variable.c (free_variable_set): New function.
1961 * variable.h: Declare it.
1963 * read.c (read_all_makefiles): Makefile names are kept in the
1964 strcache, so there's never any need to alloc/free them.
1967 * main.c (main): Add "archives" to the .FEATURES variable if
1968 archive support is enabled.
1969 * doc/make.texi (Special Variables): Document it.
1971 2006-02-13 Paul D. Smith <psmith@gnu.org>

1979 * (ALL FILES): Updated copyright and license notices.
1981 2006-02-10 Paul D. Smith <psmith@gnu.org>
1983 A new internal capability: the string cache is a read-only cache
1984 of strings, with a hash table interface for fast lookup. Nothing
1985 in the cache will ever be freed, so there's no need for reference
1986 counting, etc. This is the beginning of a full solution for
1987 Savannah bug #15182, but for now we only store makefile names here.
1989 * strcache.c: New file. Implement a read-only string cache.
1990 * make.h: Add prototypes for new functions.
1991 * main.c (initialize_global_hash_tables): Initialize the string cache.
1992 (print_data_base): Print string cache stats.
1993 * read.c (eval_makefile): Use the string cache to store makefile
1994 names. Rewrite the string allocation to be sure we free everything.
1996 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1998 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1999 directory time stamp didn't change, except on FAT filesystems.
2000 Suggested by J. David Bryan <jdbryan@acm.org>.

2005 (func_and): Implement a short-circuiting AND function.
2006 (function_table_init): Update the table with the new functions.
2007 * doc/make.texi (Conditional Functions): Changed the "if" section
2008 to one on general conditional functions. Added documentation for
2009 $(and ...) and $(or ...) functions.

2021 * vpath.c (selective_vpath_search): If the file we find has a
2022 timestamp from -o or -W, use that instead of the real time.

2024 -W, don't overwrite it with the real mtime.

2030 (process_signal, process_last_err, process_exit_code): Manage
2031 invalid handle values.

2035 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
2036 * README.cvs: Updates for building from CVS.
2038 2006-02-05 Paul D. Smith <psmith@gnu.org>

2042 Fixes Savannah bug #15533.
2043 * filedef.h (struct file): Add a new LAST pointer.
2045 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
2046 the comparison. For 64-bits systems the result of the subtraction
2047 might not fit into an int. Use comparison instead.
2048 Fixes Savannah bug #15534.
2050 * doc/make.texi: Update the chapter on writing commands to reflect
2051 the changes made in 3.81 for backslash/newline and SHELL handling.
2053 2006-02-01 Paul D. Smith <psmith@gnu.org>
2055 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
2056 variable st is not used when it's not initialized.
2057 Patch from Eli Zaretskii <eliz@gnu.org>.

2069 * prepare_w32.bat: Remove this file from the distribution.
2071 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2073 * remake.c (update_goal_chain): Set g->changed instead of
2074 incrementing it, as it is only 8-bit wide, and could overflow if
2075 many commands got started in update_file.

2089 are already more children than sub_proc.c can handle, behave as if
2090 the load were too high.
2091 (start_job_command): Fix a typo in error message when process_easy
2094 2006-01-14 Eli Zaretskii <eliz@gnu.org>
2096 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
2097 the shell is not sh.exe.
2099 * job.c (create_batch_file): Renamed from create_batch_filename;
2100 all callers changed. Don't close the temporary file; return its
2101 file descriptor instead. New arg FD allows to return the file
2103 (construct_command_argv_internal): Use _fdopen instead of fopen to
2104 open the batch file.
2106 2006-01-04 Paul D. Smith <psmith@gnu.org>
2108 * readme.vms: Updates for case-insensitive VMS file systems from
2109 Hartmut Becker <Hartmut.Becker@hp.com>.
2110 * dir.c (vms_hash): Ditto.
2111 * vmsify.c (copyto): Ditto.
2112 * vmsfunctions.c (readdir): Ditto.
2114 * make.1: Add a section on the exit codes for make.
2116 * doc/make.texi: A number of minor updates to the documentation.
2118 2006-01-03 Paul D. Smith <psmith@gnu.org>
2120 * remake.c (update_file_1): Mark a prerequisite changed if it
2123 * read.c (eval): Be sure to strip off trailing whitespace from the
2124 prerequisites list properly. Also, initialize all fields in
2125 struct dep when creating a new one.
2127 2005-12-28 Paul D. Smith <psmith@gnu.org>
2129 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2130 disable warnings for MSC.
2131 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2133 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2135 * doc/make.texi (Execution): Add a footnote about changes in
2136 handling of backslash-newline sequences. Mention the differences
2137 on MS-DOS and MS-Windows.
2139 * NEWS: More details about building the MinGW port and a pointer
2140 to README.W32. Fix the section name that describes the new
2141 backward-incompatible processing of backslash-newline sequences.
2142 The special processing of SHELL set to "cmd" is only relevant to
2143 MS-Windows, not MS-DOS.
2145 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2147 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2148 to DWORD, to avoid compiler warnings.
2149 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2150 use %ld in format, to avoid compiler warnings.
2152 * doc/make.texi (Special Targets): Fix a typo.
2153 (Appending): Fix cross-reference to Setting.
2154 (Special Variables, Secondary Expansion, File Name Functions)
2155 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2156 periods after a sentence.
2157 (Execution): Add @: after "e.g.".
2158 (Environment): Fix punctuation.
2159 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2160 (Shell Function, Target-specific): Add @: after "vs."
2162 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2164 * read.c (record_target_var): Initialize variable's export field
2165 with v_default instead of leaving it "initialized" by whatever
2166 garbage happened to be on the heap.
2168 2005-12-12 Paul D. Smith <psmith@gnu.org>
2170 * make.1: Fix some display errors and document all existing options.
2171 Patch by Mike Frysinger <vapier@gentoo.org>.
2173 2005-12-11 Paul D. Smith <psmith@gnu.org>
2175 * implicit.c (pattern_search): If 2nd expansion is not set for
2176 this implicit rule, replace the pattern with the stem directly,
2177 and don't re-expand the variable list. Along with the other
2178 .SECONDEXPANSION changes below, fixes bug #13781.
2180 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2182 * implicit.c (pattern_search): Mark other files that this rule
2183 builds as targets so that they are not treated as intermediates
2184 by the pattern rule search algorithm. Fixes bug #13022.
2186 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2188 * remake.c (notice_finished_file): Propagate the change of
2189 modification time to all the double-colon entries only if
2190 it is the last one to be updated. Fixes bug #14334.
2192 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2194 * function.c (func_flavor): Implement the flavor function which
2195 returns the flavor of a variable.
2196 * doc/make.texi (Functions for Transforming Text): Document it.
2197 * NEWS: Add it to the list of new functions.
2199 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2201 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2203 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2204 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2206 2005-10-26 Paul Smith <psmith@gnu.org>
2208 * read.c (record_files): Don't set deps flags if there are no deps.
2209 * maintMakefile: We only need to build the templates when we are
2210 creating a distribution, so don't do it for "all".
2212 2005-10-24 Paul D. Smith <psmith@gnu.org>
2214 Make secondary expansion optional: its enabled by declaring the
2215 special target .SECONDEXPANSION.
2217 * NEWS: Update information on second expansion capabilities.
2218 * doc/make.texi (Secondary Expansion): Document the
2219 .SECONDEXPANSION special target and its behavior.
2220 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2221 prerequisite list was found in a static pattern rule.
2222 (free_dep_chain): Declare a prototype.
2223 * file.c (parse_prereqs): New function: break out some complexity
2225 (expand_deps): If we aren't doing second expansion, replace % with
2226 the stem for static pattern rules. Call the new function.
2227 * filedef.h (parse_prereqs): Declare a prototype.
2228 * implicit.c (pattern_search): Initialize the new staticpattern
2230 * main.c (second_expansion): Declare a global variable to remember
2231 if the special target has been seen. Initialize the new
2232 staticpattern field for prerequisites.
2233 * make.h: Extern for second_expansion.
2234 * misc.c (free_dep_chain): New function: frees a struct dep list.
2235 * read.c (read_all_makefiles): Initialize the staticpattern field.
2236 (eval_makefile): Ditto.
2237 (record_files): Check for the .SECONDEXPANSION target and set
2238 second_expansion global if it's found.
2239 Use the new free_dep_chain() instead of doing it by hand.
2240 Set the staticpattern field for prereqs of static pattern targets.
2242 2005-10-16 Paul D. Smith <psmith@gnu.org>
2244 * main.c (main): Set CURDIR to be a file variable instead of a
2245 default, so that values of CURDIR inherited from the environment
2246 won't override the make value.
2248 2005-09-26 Paul D. Smith <psmith@gnu.org>
2250 * job.c (construct_command_argv_internal): If the line is empty
2251 remember to free the temporary argv strings.
2254 2005-09-16 Paul D. Smith <psmith@gnu.org>
2256 * job.c (start_job_command): The noerror flag is a boolean (single
2257 bit); set it appropriately.
2258 Reported by Mark Eichin <eichin@metacarta.com>
2260 2005-08-29 Paul D. Smith <psmith@gnu.org>
2262 * function.c (func_error): On Windows, output from $(info ...)
2263 seems to come in the wrong order. Try to force it with fflush().
2265 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2267 * read.c (record_files): Move code that sets stem for static
2268 pattern rules out of the if (!two_colon) condition so it is
2269 also executed for two-colon rules. Fixes Savannah bug #13881.
2271 2005-08-08 Paul D. Smith <psmith@gnu.org>
2273 * make.h: Don't test that __STDC__ is non-0. Some compilers
2274 (Windows for example) set it to 0 to denote "ISO C + extensions".
2277 2005-08-07 Paul D. Smith <psmith@gnu.org>
2279 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2280 conditional (slightly different version of a fix from Eli).
2282 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2283 If make is running in parallel without -k and two jobs die in a
2284 row, but not too close to each other, then make will quit without
2285 waiting for the rest of the jobs to die.
2287 * main.c (die): Don't reset err before calling reap_children() the
2288 second time: we still want it to be in the error condition.
2289 * job.c (reap_children): Use a static variable, rather than err,
2290 to control whether or not the error message should be printed.
2292 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2294 * w32/subproc/sub_proc.c: Include signal.h.
2295 (process_pipe_io, process_file_io): Pass a pointer to a local
2296 DWORD variable to GetExitCodeProcess. If the exit code is
2297 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2299 * job.c [WINDOWS32]: Include windows.h.
2300 (main_thread) [WINDOWS32]: New global variable.
2301 (reap_children) [WINDOWS32]: Get the handle for the main thread
2302 and store it in main_thread.
2304 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2305 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2306 doing anything else. When we are done, close the main thread
2307 handle and exit with status 130.
2309 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2311 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2314 * main.c (find_and_set_default_shell): If found a DOSish shell,
2315 set sh_found and the value of default_shell, and report the
2316 findings in debug mode.
2318 * job.c (construct_command_argv_internal): Check unixy_shell, not
2319 no_default_sh_exe, to decide whether to use Unixy or DOSish
2322 * README.W32: Update with info about the MinGW build.
2324 * build_w32.bat: Support MinGW.
2326 * w32/subproc/build.bat: Likewise.
2328 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2329 printing DWORD args.
2331 * function.c (windows32_openpipe): Fix format strings for printing
2334 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2336 (start_job_command): Fix format string for printing the result of
2338 (start_job_command) [WINDOWS32]: Do not define.
2339 (exec_command): Fix format string for printing HANDLE args.
2341 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2342 to avoid compiler warnings.
2343 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2344 (Note: some of these fixes were submitted independently by J. Grant)
2346 2005-07-30 J. Grant <jg@jguk.org>
2348 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2349 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2350 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2352 2005-07-15 Paul Smith <psmith@gnu.org>
2354 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2355 we don't have a POSIX shell, then revert to the old
2356 backslash-newline behavior (where they are stripped).
2359 2005-07-08 Paul D. Smith <psmith@gnu.org>
2361 * config.h.W32.template: Reorder to match the standard config.h,
2362 for easier comparisons.
2363 From J. Grant <jg@jguk.org>
2365 * maintMakefile: Remove .dep_segment before overwriting it, in
2366 case it's not writable or noclobber is set.
2367 * expand.c (variable_expand_string): Cast result of pointer
2368 arithmetic to avoid a warning.
2369 * main.c (switches): Add full-fledged final initializer.
2371 2005-07-06 Paul D. Smith <psmith@gnu.org>
2373 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2374 * signame.c (strsignal): If we found _sys_siglist[] or
2375 __sys_siglist[] use those instead of sys_siglist[].
2376 From Albert Chin <china@thewrittenword.com>
2378 2005-07-04 Paul D. Smith <psmith@gnu.org>
2380 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2381 globfree(); set up to use the GNU versions.
2382 From Martin Zinser <zinser@zinser.no-ip.info>
2384 2005-07-03 Paul D. Smith <psmith@gnu.org>
2386 From J. Grant <jg@jguk.org>:
2388 * README.W32.template: Update the Windows and tested MSVC versions.
2389 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2390 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2391 * build_w32.bat: Ditto.
2392 * w32/subproc/build.bat: Ditto.
2394 2005-06-28 Paul D. Smith <psmith@gnu.org>
2396 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2397 declaration was checked but not present.
2399 2005-06-27 Paul D. Smith <psmith@gnu.org>
2401 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2402 to unsigned long. Fixes Savannah bug #13550.
2404 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2405 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2406 Fixes Savannah bug #13551.
2408 2005-06-26 Paul D. Smith <psmith@gnu.org>
2410 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2411 it if ANSI_STRING is not set.
2413 2005-06-25 Paul D. Smith <psmith@gnu.org>
2415 * read.c (eval): If no filenames are passed to any of the
2416 "include" variants, don't print an error.
2417 * doc/make.texi (Include): Document this.
2418 Fixes Savannah bug #1761.
2420 * job.c (construct_command_argv_internal): Sanitize handling of
2421 backslash/newline pairs according to POSIX: that is, keep the
2422 backslash-newline in the command script, but remove a following
2423 TAB character, if present. In the fast path, make sure that the
2424 behavior matches what the shell would do both inside and outside
2425 of quotes. In the slow path, quote the backslash and put a
2426 literal newline in the string.
2427 Fixes Savannah bug #1332.
2428 * doc/make.texi (Execution): Document the new behavior and give
2430 * NEWS: Make a note of the new behavior.
2432 * make.h [WINDOWS32]: #include <direct.h>.
2433 Fixes Savannah bug #13478.
2435 * remake.c (name_mtime): If the stat() of a file fails and the -L
2436 option was given and the file is a symlink, take the best mtime of
2437 the symlink we can get as the mtime of the file and don't fail.
2438 Fixes Savannah bug #13280.
2440 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2441 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2442 inside a variable reference. Make this function static as it's
2444 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2445 parsing an unexpanded line looking for semicolons.
2446 Fixes Savannah bug #1454.
2447 * misc.c (remove_comments): Move this to read.c and make it static
2448 as it's only used there. Call find_char_unquote() with new arg.
2449 * make.h: Remove prototypes for find_char_unquote() and
2450 remove_comments() since they're static now.
2452 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2453 its export flag and obtain its value. When we need to re-exec,
2454 increment the value and add it into the environment.
2455 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2456 * NEWS: Mention MAKE_RESTARTS.
2457 * main.c (always_make_set): New variable. Change the -B option to
2458 set this one instead.
2459 (main): When checking makefiles, only set always_make_flag if
2460 always_make_set is set AND the restarts flag is 0. When building
2461 normal targets, set it IFF always_make_set is set.
2462 (main): Avoid infinite recursion with -W, too: only set what-if
2463 files to NEW before we check makefiles if we've never restarted
2464 before. If we have restarted, set what-if files to NEW _after_ we
2466 Fixes Savannah bug #7566:
2468 2005-06-17 Paul D. Smith <psmith@gnu.org>
2470 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2471 in the prerequisites list.
2473 2005-06-12 Paul D. Smith <psmith@gnu.org>
2475 Fix Savannah bug # 1328.
2477 * configure.in: Check for atexit().
2478 * misc.c (close_stdout): Test stdout to see if writes to it have
2479 failed. If so, be sure to exit with a non-0 error code. Based on
2480 code found in gnulib.
2481 * make.h: Prototype.
2482 * main.c (main): Install close_stdout() with atexit().
2484 2005-06-10 Paul D. Smith <psmith@gnu.org>
2486 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2488 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2489 headers; make vmsWaitForChildren() static; extern vmsify().
2490 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2491 Don't create child_execute_job() here (it's in vmsjobs.c).
2492 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2494 2005-06-09 Paul D. Smith <psmith@gnu.org>
2496 * variable.c (push_new_variable_scope): File variables point
2497 directly to the global_setlist variable. So, inserting a new
2498 scope in front of that has no effect on those variables: they
2499 don't go through current_variable_set_list. If we're pushing a
2500 scope and the current scope is global, push it "the other way" so
2501 that the new setlist is in the global_setlist variable, and
2502 next points to a new setlist with the global variable set.
2503 (pop_variable_scope): Properly undo a push with the new
2505 Fixes Savannah bug #11913.
2507 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2509 * job.c (reap_children): Don't die of the command failed but
2510 the dontcare flag is set. Fixes Savannah bug #13216.
2512 * implicit.c (pattern_search): When creating a target from
2513 an implicit rule match, lookup pattern target and set precious
2514 flag in a newly created target. Fixes Savannah bug #13218.
2516 2005-05-13 Paul D. Smith <psmith@gnu.org>
2518 Implement "if... else if... endif" syntax.
2520 * read.c (eval): Push all checks for conditional words ("ifeq",
2521 "else", etc.) down into the conditional_line() function.
2522 (conditional_line): Rework to allow "else if..." clause. New
2523 return value -2 for lines which are not conditionals. The
2524 ignoring flag can now also be 2, which means "already parsed a
2525 true branch". If that value is seen no other branch of this
2526 conditional can be considered true. In the else parsing if there
2527 is extra text after the else, invoke conditional_line()
2528 recursively to see if it's another conditional. If not, it's an
2529 error. If so, raise the conditional value to this level instead
2530 of creating a new conditional nesting level. Special check for
2531 "else" and "endif", which aren't allowed on the "else" line.
2532 * doc/make.texi (Conditional Syntax): Document the new syntax.
2534 2005-05-09 Paul D. Smith <psmith@gnu.org>
2536 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2537 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2538 recurses to the w32 directory, even on non-Windows systems. Use
2539 the method suggested in the automake manual.
2540 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2541 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2543 2005-05-07 Paul D. Smith <psmith@gnu.org>
2545 * main.c (die): If we're dying with a fatal error (not that a
2546 command has failed), write back any leftover tokens before we go.
2548 * job.c (set_child_handler_action_flags): If there are jobs
2549 waiting for the load to go down, set an alarm to go off in 1
2550 second. This allows us to wake up from a potentially long-lasting
2551 read() and start a new job if the load has gone down. Turn it off
2553 (job_noop): Dummy signal handler function.
2554 (new_job): Invoke it with the new semantics.
2556 * docs/make.texi: Document secondary expansion. Various cleanups
2559 2005-05-03 Paul D. Smith <psmith@gnu.org>
2561 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2562 the targets which are to ultimately be made are called "goals";
2563 see the GNU make manual. Also, MAKECMDGOALS, etc.
2565 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2566 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2567 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2569 2005-05-02 Paul D. Smith <psmith@gnu.org>
2571 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2572 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2573 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2574 functions to vmsjobs.c. #include it into jobs.c.
2576 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2577 jobserver tokens. I found that this happens when an exported
2578 recursive variable contains a $(shell ...) function reference: in
2579 this situation we could "forget" to write back a token.
2581 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2582 we have. It's not reliable to depend on the number of children in
2583 our linked list so keep a separate count.
2584 (new_job): Check jobserver_tokens rather than children &&
2585 waiting_jobs. Increment jobserver_tokens when we get one.
2586 (free_child): If jobserver_tokens is 0, internal error. If it's
2587 >1, write a token back to the jobserver pipe (we don't write a
2588 token for the "free" job). Decrement jobserver_tokens.
2590 * main.c: Add variable master_job_slots.
2591 (main): Set it to hold the number of jobs requested if we're the
2592 master process, when using the jobserver.
2593 (die): Sanity checks: first test jobserver_tokens to make sure
2594 this process isn't holding any tokens we didn't write back.
2595 Second, if master_job_slots is set count the tokens left in the
2596 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2598 2005-04-24 Paul D. Smith <psmith@gnu.org>
2600 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2601 with -l# can lose jobserver tokens, because waiting jobs are not
2602 consulted properly when checking for the "free" token.
2604 * job.c (free_child): Count waiting_jobs as having tokens.
2605 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2606 handle jobs waiting for the load to drop.
2608 2005-04-23 Paul D. Smith <psmith@gnu.org>
2610 * main.c (main): Be careful to not core if a variable setting in
2611 the environment doesn't contain an '='. This is illegal but can
2612 happen in broken setups.
2613 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2615 2005-04-12 Paul D. Smith <psmith@gnu.org>
2617 The second expansion feature causes significant slowdown. Timing
2618 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2619 read the makefile before the feature, to 11+s to do the same
2620 operations after the feature. Additionally, memory usage
2621 increased drastically. To fix this I added some intelligence that
2622 avoids the overhead of the second expansion unless it's required.
2624 * dep.h: Add a new boolean field, need_2nd_expansion.
2626 * read.c (eval): When creating the struct dep for the target,
2627 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2628 (record_files): If there's a "%" in a static pattern rule, it gets
2629 converted to "$*" so set need_2nd_expansion to 1.
2631 * file.c (expand_deps): Rework to be more efficient. Only perform
2632 initialize_file_variables(), set_file_variables(), and
2633 variable_expand_for_file() if the need_2nd_expansion is set.
2635 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2636 (pattern_search): Ditto.
2637 * main.c (handle_non_switch_argument): Ditto.
2639 * read.c (read_all_makefiles): Ditto.
2640 (eval_makefile): Ditto.
2642 2005-04-07 Paul D. Smith <psmith@gnu.org>
2644 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2645 * variable.c (sync_Path_environment): Ditto.
2646 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2648 * main.c (main): Define the .FEATURES variable.
2649 * NEWS: Announce .FEATURES.
2650 * doc/make.texi (Special Variables): Document .FEATURES.
2652 * remake.c (check_dep): If a file is .PHONY, update it even if
2653 it's marked intermediate. Fixes Savannah bug #12331.
2655 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2657 * file.c (expand_deps): Factor out the second expansion and
2658 prerequisite line parsing logic from snap_deps().
2660 * file.c (snap_deps): Use expand_deps(). Expand and parse
2661 prerequisites of the .SUFFIXES special target first. Fixes
2662 Savannah bug #12320.
2664 2005-03-13 Paul D. Smith <psmith@gnu.org>
2666 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2669 2005-03-11 Paul D. Smith <psmith@gnu.org>
2671 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2672 available, not undefined (from Earnie Boyd).
2674 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2676 * implicit.c (pattern_search): Mark an intermediate target as
2677 precious if it happened to be a prerequisite of some (other)
2678 target. Fixes Savannah bug #12267.
2680 2005-03-09 Paul D. Smith <psmith@gnu.org>
2682 * read.c (eval_makefile): Add alloca(0).
2683 (eval_buffer): Ditto.
2685 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2687 * main.c (main): Use o_file instead of o_default when defining
2688 the .DEFAULT_TARGET special variable.
2689 * read.c (eval): Use define_variable_global() instead of
2690 define_variable() when setting new value for the .DEFAULT_TARGET
2691 special variable. Fixes Savannah bug #12266.
2693 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2695 * imlicit.c (pattern_search): Mark files for which an implicit
2696 rule has been found as targets. Fixes Savannah bug #12202.
2698 2005-03-04 Paul D. Smith <psmith@gnu.org>
2701 * doc/make.texi (Automatic Variables): Document $|.
2703 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2705 * read.c (record_files): Instead of substituting % with
2706 actual stem value in dependency list replace it with $*.
2707 This fixes stem triple expansion bug.
2709 * implicit.c (pattern_search): Copy stem to a separate
2710 buffer and make it a properly terminated string. Assign
2711 this buffer instead of STEM (which is not terminated) to
2712 f->stem. Instead of substituting % with actual stem value
2713 in dependency list replace it with $*. This fixes stem
2714 triple expansion bug.
2716 2005-03-01 Paul D. Smith <psmith@gnu.org>
2718 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2719 on Windows, as it takes a handle not a pid. Just exit.
2720 Fix from patch #3679, provided by Alessandro Vesely.
2722 * configure.in: Update check for sys_siglist[] from autoconf manual.
2723 * signame.c (strsignal): Update to use the new autoconf macro.
2725 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2727 * read.c (record_files): Add a check for the list of prerequisites
2728 of a static pattern rule being empty. Fixes Savannah bug #12180.
2730 2005-02-28 Paul D. Smith <psmith@gnu.org>
2732 * doc/make.texi (Text Functions): Update docs to allow the end
2733 ordinal for $(wordlist ...) to be 0.
2734 * function.c (func_wordlist): Fail if the start ordinal for
2735 $(wordlist ...) is <1. Matches documentation.
2736 Resolves Savannah support request #103195.
2738 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2739 previously we were stopping when !-q, exactly the opposite. This
2740 has been wrong since version 1.34, in 1994!
2741 (update_file): If we got an error don't break out to run more
2742 double-colon rules: just return immediately.
2743 Fixes Savannah bug #7144.
2745 2005-02-27 Paul D. Smith <psmith@gnu.org>
2747 * misc.c (end_of_token): Make argument const.
2748 * make.h: Update prototype.
2750 * function.c (abspath, func_realpath, func_abspath): Use
2751 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2752 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2753 * read.c (record_files): Ditto.
2754 * variable.c (do_variable_definition): Ditto.
2756 * function.c (func_error): Create a new function $(info ...) that
2757 simply prints the message to stdout with no extras.
2758 (function_table_init): Add new function to the table.
2759 * NEWS: Add $(info ...) reference.
2760 * doc/make.texi (Make Control Functions): Document it.
2762 New feature: if the system supports symbolic links, and the user
2763 provides the -L/--check-symlink-time flag, then use the latest
2764 mtime between the symlink(s) and the target file.
2766 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2767 readlink(). If both are available, define MAKE_SYMLINKS.
2768 * main.c: New variable: check_symlink_flag.
2769 (usage): Add a line for -L/--check-symlink-times to the help string.
2770 (switches): Add -L/--check-symlink-times command line argument.
2771 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2772 print a warning and disable it again.
2773 * make.h: Declare check_symlink_flag.
2774 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2775 if the file is a symlink then check each link in the chain and
2776 choose the NEWEST mtime we find as the mtime for the file. The
2777 newest mtime might be the file itself!
2778 * NEWS: Add information about this new feature.
2779 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2781 Avoid core dumps described in Savannah bug # 12124:
2783 * file.c: New variable snapped_deps remember whether we've run
2785 (snap_deps): Set it.
2786 * filedef.h: Extern it.
2787 * read.c (record_files): Check snapped_deps; if it's set then
2788 we're trying to eval a new target/prerequisite relationship from
2789 within a command script, which we don't support. Fatal.
2791 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2793 Implementation of the .DEFAULT_TARGET special variable.
2795 * read.c (eval): If necessary, update default_target_name when
2797 * read.c (record_files): Update default_target_file if
2798 default_target_name has changed.
2799 * main.c (default_target_name): Define.
2800 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2801 default_target_name is set use default_target_file as a root
2803 * filedef.h (default_target_name): Declare.
2804 * dep.h (free_dep_chain):
2805 * misc.c (free_dep_chain): Change to operate on struct nameseq
2806 and change name to free_ns_chain.
2807 * file.c (snap_deps): Update to use free_ns_chain.
2809 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2811 Implementation of the second expansion in explicit rules,
2812 static pattern rules and implicit rules.
2814 * read.c (eval): Refrain from chopping up rule's dependencies.
2815 Store them in a struct dep as a single dependency line. Remove
2816 the code that implements SySV-style automatic variables.
2818 * read.c (record_files): Adjust the code that handles static
2819 pattern rules to expand all percents instead of only the first
2820 one. Reverse the order in which dependencies are stored so that
2821 when the second expansion reverses them again they appear in
2822 the makefile order (with some exceptions, see comments in
2823 the code). Remove the code that implements SySV-style automatic
2826 * file.c (snap_deps): Implement the second expansion and chopping
2827 of dependency lines for explicit rules.
2829 * implicit.c (struct idep): Define an auxiliary data type to hold
2830 implicit rule's dependencies after stem substitution and
2833 * implicit.c (free_idep_chain): Implement.
2835 * implicit.c (get_next_word): Implement helper function for
2836 parsing implicit rule's dependency lines into words taking
2837 into account variable expansion requests. Used in the stem
2840 * implicit.c (pattern_search): Implement the second expansion
2841 for implicit rules. Also fixes bug #12091.
2843 * commands.h (set_file_variables): Declare.
2844 * commands.c (set_file_variables): Remove static specifier.
2846 * dep.h (free_dep_chain): Declare.
2847 * misc.c (free_dep_chain): Implement.
2849 * variable.h (variable_expand_for_file): Declare.
2850 * expand.c (variable_expand_for_file): Remove static specifier.
2852 * make.h (strip_whitespace): Declare.
2853 * function.c (strip_whitespace): Remove static specifier.
2855 2005-02-26 Paul D. Smith <psmith@gnu.org>
2857 * main.c (main): Check for ferror() when reading makefiles from stdin.
2858 Apparently some shells in Windows don't close pipes properly and
2861 2005-02-24 Jonathan Grant <jg@jguk.org>
2863 * configure.in: Add MinGW configuration options, and extra w32 code
2865 * Makefile.am: Add MinGW configuration options, and extra w32 code
2867 * main.c: Determine correct program string (after last \ without .exe).
2868 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2870 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2871 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2872 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2873 environment support.
2875 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2877 * function.c (func_shell): When initializing error_prefix, check
2878 that reading file name is not null. This fixes long-standing
2879 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2881 2005-02-09 Paul D. Smith <psmith@gnu.org>
2883 * maintMakefile: Update the CVS download URL to simplify them.
2884 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2885 downloading the .texi files from Savannah now.
2887 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2889 * main.c (handle_non_switch_argument): Only add variables to
2890 command_variables if they're not already there: duplicate settings
2891 waste space and can be confusing to read.
2893 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2894 this header is never included by non-WINDOWS32 code, and it
2895 requires <config.h> to define which isn't always included first.
2897 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2898 testing MINGW32 versions.
2900 * main.c (log_working_directory): flush stdout to be sure the WD
2901 change is printed before any stderr messages show up.
2903 2005-02-01 Paul D. Smith <psmith@gnu.org>
2905 * maintMakefile (po_repo): Update the GNU translation site URL.
2907 2004-12-01 Paul D. Smith <psmith@gnu.org>
2909 * main.c (main): Change char* env_shell to struct variable shell_var.
2910 * variable.c (target_environment): Use new shell_var.
2912 2004-11-30 Paul D. Smith <psmith@gnu.org>
2914 * configure.in: The old way we avoided creating build.sh from
2915 build.sh.in before build.sh.in exists doesn't work anymore; we
2916 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2917 the help!). This also keeps automake from complaining.
2918 * Makefile.am (README): Add a dummy target so automake won't
2919 complain that this file doesn't exist when we checkout from CVS.
2920 * maintMakefile (.dep_segment): Rewrite this rule since newer
2921 versions of automake don't provide DEP_FILES.
2923 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2925 Implementation of `realpath' and `abspath' built-in functions.
2927 * configure.in: Check for realpath.
2928 * function.c (abspath): Return an absolute file name that does
2929 not contain any `.' or `..' components, nor repeated `/'.
2930 * function.c (func_abspath): For each name call abspath.
2931 * function.c (func_realpath): For each name call realpath
2932 from libc or delegate to abspath if realpath is not available.
2933 * doc/make.texi (Functions for File Names): Document new functions.
2934 * doc/make.texi (Quick Reference): Ditto.
2936 2004-11-28 Paul D. Smith <psmith@gnu.org>
2938 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2939 arguments. Fixes bug #10252.
2941 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2943 * main.c (main): Set SHELL to v_noexport by default. Remember the
2944 original environment setting of SHELL in the env_shell variable.
2945 * main.h: Export new env_shell variable.
2946 * variable.c (target_environment): If we find a v_noexport
2947 variable for SHELL, add a SHELL variable with the env_shell value.
2948 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2949 * doc/make.texi (Variables/Recursion): Ditto.
2951 2004-11-28 Paul D. Smith <psmith@gnu.org>
2953 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2954 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2955 Patch by Alessandro Vesely.
2957 2004-11-12 Paul D. Smith <psmith@gnu.org>
2959 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2960 the command line if it's inside a string.
2961 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2963 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2965 * function.c (func_lastword): New function: return last word
2966 from the list of words.
2967 * doc/make.texi: Document $(lastword ). Fix broken links in
2968 Quick Reference section.
2970 2004-10-06 Paul D. Smith <psmith@gnu.org>
2972 Apply patch from Alessandro Vesely, provided with bug # 9748.
2973 Fix use of tmpnam() to work with Borland C.
2975 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2976 construction of a temporary filename, and call new function
2977 create_batch_filename().
2978 (create_batch_filename) [WINDOWS32]: New function to create a
2981 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2983 * read.c (record_target_var): Expand simple pattern-specific
2985 * variable.c (initialize_file_variables): Do not expand simple
2986 pattern-specific variable.
2988 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2990 * remake.c (update_file_1): When rebuilding makefiles inherit
2991 dontcare flag from a target that triggered update.
2993 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2995 * variable.c (initialize_file_variables): Mark pattern-specific
2996 variable as a per-target and copy export status.
2998 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
3000 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
3002 * implicit.c (pattern_search): When considering an implicit rule's
3003 prerequisite check that it is actually a target rather then
3004 just an entry in the file hashtable.
3006 2004-09-21 Paul D. Smith <psmith@gnu.org>
3008 * read.c (readstring): Fix some logic errors in backslash handling.
3009 (eval): Remove some unnecessary processing in buffer handling.
3010 (record_target_var): Assert that parse_variable_definition() succeeded.
3011 Reported by: Markus Mauhart <qwe123@chello.at>.
3013 * misc.c: Removed the sindex() function. All instances of this
3014 function were trivially replaceable by the standard strstr()
3015 function, and that function will always have better (or certainly
3016 no worse) performance than the very simple-minded algorithm
3017 sindex() used. This can matter with complex makefiles.
3018 * make.h: Remove the prototype for sindex().
3019 * function.c (subst_expand): Convert sindex() call to strstr().
3020 This means we no longer need to track the TLEN value so remove that.
3021 (func_findstring): Convert sindex() to strstr().
3022 * commands.c (chop_commands): Convert sindex() calls to strstr().
3023 Suggested by: Markus Mauhart <qwe123@chello.at>.
3025 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
3026 idea behind Savannah Patch #3144 from david.baird@homemail.com.
3027 If SHELL is set to CMD.EXE then assume it's batch-mode and
3028 non-unixy. I wrote the code differently from the patch, though,
3029 to make it safer. This also resolves bug #9174.
3031 2004-09-20 Paul D. Smith <psmith@gnu.org>
3033 * expand.c (variable_expand_string): Modify to invoke
3034 patsubst_expand() instead of subst_expand(); the latter didn't
3035 handle suffix patterns correctly.
3036 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
3037 was used only from variable_expand_string() and is no longer used
3039 (func_subst): Ditto, on call to subst_expand().
3040 (patsubst_expand): Require the percent pointers to point to the
3041 character after the %, not to the % itself.
3042 * read.c (record_files): New call criteria for patsubst_expand().
3043 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
3044 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
3046 2004-09-19 Paul D. Smith <psmith@gnu.org>
3048 * function.c (subst_expand): Fix a check in by_word: look for a
3049 previous blank if we're beyond the beginning of the string, not
3050 the beginning of the word.
3051 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3053 2004-05-16 Paul D. Smith <psmith@gnu.org>
3055 * remake.c (update_goal_chain): Change the argument specifying
3056 whether we're rebuilding makefiles to be a global variable,
3057 REBUILDING_MAKEFILES.
3058 (complain): Extract the code that complains about no rules to make
3059 a target into a separate function.
3060 (update_file_1): If we tried to rebuild a file during the makefile
3061 rebuild phase and it was dontcare, then no message was printed.
3062 If we then try to build the same file during the normal build,
3063 print a message this time.
3064 (remake_file): Don't complain about un-remake-able files when
3065 we're rebuilding makefiles.
3067 2004-05-11 Paul D. Smith <psmith@gnu.org>
3069 * job.c (construct_command_argv_internal): OS/2 patches from
3070 Andreas Buening <andreas.buening@nexgo.de>.
3072 2004-05-10 Paul D. Smith <psmith@gnu.org>
3074 * remake.c (update_file): Don't walk the double-colon chain unless
3075 this is a double-colon rule. Fix suggested by Boris Kolpackov
3076 <boris@kolpackov.net>.
3078 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3079 * readme.vms: New section describing OpenVMS support and issues.
3080 * default.c (default_variables): Add support for IA64.
3081 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3082 without some privilege aborts make with the error
3083 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3084 pressing Ctrl+Y and the input device is no terminal. The change
3085 catches this error and just continues.
3087 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3089 2004-04-25 Paul D. Smith <psmith@gnu.org>
3091 * commands.c (set_file_variables): Set $< properly in the face of
3092 order-only prerequisites.
3093 Patch from Boris Kolpackov <boris@kolpackov.net>
3095 2004-04-21 Bob Byrnes <byrnes@curl.com>
3097 * main.c (main): Notice failures to remake makefiles.
3099 2004-03-28 Paul D. Smith <psmith@gnu.org>
3101 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3103 * job.c: No default shell for RISC OS.
3104 (load_too_high): Hard-code the return to 1.
3105 (construct_command_argv_internal): No sh_chars or sh_cmds.
3106 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3108 2004-03-20 Paul D. Smith <psmith@gnu.org>
3110 * variable.c (do_variable_definition): Don't append from the
3111 global set if a previous non-appending target-specific variable
3112 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3115 * expand.c (reference_variable): Don't give up on variables with
3116 no value that have the target-specific append flag set: they might
3117 have a value after all. Reported by Oliver Schmidt
3118 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3119 <nikulin@dx1cmd.inp.nsk.su>.
3121 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3122 refer to absolute pathnames in directories that don't exist: some
3123 portion of the makefile could create those directories before we
3124 match the pattern. Fixes bugs #775 and #108.
3126 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3128 * main.c (main): Free makefile_mtimes if we have any.
3129 * README.W32.template: Update documentation for the current status
3130 of the MS-Windows port.
3131 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3132 environment variable is sometimes already defined which causes the
3134 * main.c (debug_signal_handler): Only define this function if
3135 SIGUSR1 is available.
3137 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3139 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3140 * README.OS2.template: Documentation updates.
3141 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3142 link line for safety.
3143 * maintMakefile (build.sh.in): Remove an extraneous ")".
3144 * job.c (child_execute_job): Close saved FDs.
3145 * job.c (exec_command) [OS/2]: exec_command(): If the command
3146 can't be exec'ed and if the shell is not Unix-sh, then try again
3147 with argv = { "cmd", "/c", ... }. Normally, this code is never
3148 reached for the cmd shell unless the command really doesn't exist.
3149 (construct_command_argv_internal) [OS/2]: The code for cmd
3150 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3151 The CMD builtin commands are case insensitive so use strcasecmp().
3153 2004-03-19 Paul D. Smith <psmith@gnu.org>
3155 * read.c (do_define): Re-order line counter increment so the count
3156 is accurate (we were losing one line per define). Reported by
3157 Dave Yost <Dave@Yost.com>.
3159 2004-03-06 Paul D. Smith <psmith@gnu.org>
3161 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3163 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3164 * misc.c (message,error,fatal): Ditto.
3165 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3166 * config.h.W32.template: Ditto.
3167 * config.h-vms.template: Ditto.
3168 * config.ami.template: Ditto.
3170 2004-03-04 Paul D. Smith <psmith@gnu.org>
3172 * README.template: Add a note about broken /bin/sh on SunOS
3173 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3175 * misc.c (message, error, fatal): Don't use "..." if we're using
3176 varargs. ansi2knr should handle this but it doesn't work: it
3177 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3178 done. On many systems (SunOS for example) va_dcl is a #define.
3179 So, force the use of the non-"..." version on pre-ANSI compilers.
3181 * maintMakefile (sign-dist): Create some rules to help automate
3182 the new GNU ftp upload method.
3184 2004-02-24 Paul D. Smith <psmith@gnu.org>
3186 * config.h.W32.template: Add HAVE_STDARG_H
3187 * config.h-vms.template: Ditto.
3188 * config.ami.template: Ditto.
3190 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3192 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3193 * build_w32.bat: Remove extra "+".
3195 2004-02-23 Paul D. Smith <psmith@gnu.org>
3197 * make.h: Create an UNUSED macro to mark unused parameters.
3198 * (many): Clean up warnings by applying UNUSED, fixing
3199 signed/unsigned incompatibilities, etc.
3201 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3203 * filedef.h: Name the command_state enumeration.
3204 * file.c (set_command_state): Use the enumeration in the function
3207 * configure.in: Explicitly set SET_MAKE to empty, to disable
3208 MAKE=make even when no make already exists. Fix bug #3823.
3210 2004-02-22 Paul D. Smith <psmith@gnu.org>
3212 * maintMakefile: Perl script to clean up all non-CVS files. Use
3213 it on all the subdirectories for the cvs-clean target.
3215 * main.c (decode_switches): Require non-empty strings for all our
3216 string command-line options. Fixes Debian bug # 164165.
3218 * configure.in: Check for stdarg.h and varargs.h.
3219 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3220 for printing messages.
3221 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3226 A number of patches for OS/2 support from Andreas Buening
3227 <andreas.buening@nexgo.de>:
3229 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3230 disable the SIGCHLD handler.
3231 (reap_children) [OS/2]: Remove special handling of job_rfd.
3232 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3233 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3234 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3235 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3236 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3239 2004-02-21 Paul D. Smith <psmith@gnu.org>
3241 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3242 <mail@kristov.de> reports that if process_begin() fails we don't
3243 handle the error condition correctly in all cases.
3244 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3245 to have a newline on the message.
3247 * job.c (construct_command_argv_internal): Add "test" to UNIX
3248 sh_cmds[]. Fixes Savannah bug # 7606.
3250 2004-02-04 Paul D. Smith <psmith@gnu.org>
3252 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3253 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3254 Hartmut Becker <Hartmut.Becker@hp.com>.
3256 2004-01-21 Paul D. Smith <psmith@gnu.org>
3258 * job.c (load_too_high): Implement an algorithm to control the
3259 "thundering herd" problem when using -l to control job creation
3260 via the load average. The system only recomputes the load once a
3261 second but we can start many jobs in a second. To solve this we
3262 keep track of the number of jobs started in the last second and
3263 apply a weight to try to guess what a correct load would be.
3264 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3265 Also fixes bug #4693.
3266 (reap_children): Decrease the job count for this second.
3267 (start_job_command): Increase the job count for this second.
3269 * read.c (conditional_line): Expand the text after ifn?def before
3270 checking to see if it's a single word. Fixes bug #7257.
3272 2004-01-09 Paul D. Smith <psmith@gnu.org>
3274 * file.c (print_file): Recurse to print all targets in
3275 double-colon rules. Fixes bug #4518, reported (with patch) by
3276 Andrew Chatham <chatham@google.com>.
3278 2004-01-07 Paul D. Smith <psmith@gnu.org>
3280 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3281 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3282 AC_FUNC_SETVBUF_REVERSED.
3284 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3285 (MAKE Variable): Fix Savannah bug #4898.
3287 * job.c (construct_command_argv_internal): Add "!" to the list of
3288 shell escape chars. POSIX sh allows it to appear before a
3289 command, to negate the exit code. Fixes bug #6404.
3291 * implicit.c (pattern_search): When matching an implicit rule,
3292 remember which dependencies have the ignore_mtime flag set.
3293 Original fix provided in Savannah patch #2349, by Benoit
3294 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3296 2003-11-22 Paul D. Smith <psmith@gnu.org>
3298 * README.W32.template (Outputs): Clarification on -j with
3299 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3302 2003-11-02 Paul D. Smith <psmith@gnu.org>
3304 * function.c (func_if): Strip all the trailing whitespace from the
3305 condition, then don't expand it. Fixed bug # 5798.
3307 * expand.c (recursively_expand_for_file): If we're expanding a
3308 variable with no file context, then use the variable's context.
3311 2003-10-21 Paul D. Smith <psmith@gnu.org>
3313 * main.c (log_working_directory): Add newlines to printf()s.
3315 * README.cvs: Add a note to ignore warnings during autoreconf.
3317 * maintMakefile (po_repo): Set a new URL for PO file updates.
3318 (get-config/config.guess get-config/config.sub): Get these files
3319 from the Savannah config project instead of ftp.gnu.org.
3321 2003-10-05 Paul Eggert <eggert@twinsun.com>
3323 * main.c (main): Avoid potential subscript error if environ has
3326 2003-08-22 Paul D. Smith <psmith@gnu.org>
3328 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3329 systems which don't yet implement the C89 standard :-/.
3331 2003-07-18 Paul D. Smith <psmith@gnu.org>
3333 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3334 [WINDOWS32]: Initialize hash.
3336 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3338 * dir.c (read_dirstream): Provide a workaround for broken versions of
3339 the MinGW dirent structure.
3341 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3343 * w32/include/dirent.h: Add __MINGW32__ filter.
3345 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3347 * make.h: Add global declaration of *make_host.
3348 * main.c (print_usage): Remove local declaration of *make_host.
3349 (print_version): Display "This program built for ..." after Copyright
3352 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3354 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3355 execution of "makeinfo --html make.texi".
3357 2003-04-30 Paul D. Smith <psmith@gnu.org>
3359 * build.template: Make some changes to maybe allow this script to
3360 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3362 * README.OS2.template: New file for OS/2 support. Original
3363 contributed by Andreas Buening.
3364 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3367 2003-04-19 Paul D. Smith <psmith@gnu.org>
3369 Fix bug #1405: allow a target to match multiple pattern-specific
3372 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3373 variable.c, where they've always belonged.
3374 * rule.h: Move the prototypes and struct pattern_var as well.
3375 * variable.c (initialize_file_variables): Invoke
3376 lookup_pattern_var() in a loop, until no more matches are found.
3377 If a match is found, create a new variable set for the target's
3378 pattern variables. Then merge the contents of each matching
3379 pattern variable set into the target's pattern variable set.
3380 (lookup_pattern_var): Change this function to be usable
3381 in a loop. It takes a starting position: if NULL, start at the
3382 beginning; if non-NULL, start with the pattern variable after that
3383 position, and return the next matching pattern.
3384 (create_pattern_var): Create a unique instance of
3385 pattern-specific variables for every definition in the makefile.
3386 Don't combine the same pattern together. This allows us to
3387 process the variable handling properly even when the same pattern
3388 is used multiple times.
3389 (parse_variable_definition): New function: break out the parsing
3390 of a variable definition line from try_variable_definition.
3391 (try_variable_definition): Call parse_variable_definition to
3393 (print_variable_data_base): Print out pattern-specific variables.
3394 * variable.h (struct variable): Remember when a variable is
3395 conditional. Also remember its flavor.
3396 (struct pattern_var): Instead of keeping a variable set, we just
3397 keep a single variable for each pattern.
3398 * read.c (record_target_var): Each pattern variable contains only a
3399 single variable, not a set, so create it properly.
3400 * doc/make.texi (Pattern-specific): Document the new behavior.
3402 2003-04-17 Paul D. Smith <psmith@gnu.org>
3404 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3405 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3406 file/directory naming rules for VMS so I can't tell whether this
3409 2003-04-09 Paul D. Smith <psmith@gnu.org>
3411 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3412 DOS-style pathnames: backslash separators and drive specifiers.
3414 2003-03-28 Paul D. Smith <psmith@gnu.org>
3416 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3417 the intermediate flag on all targets. Fixes bug #2515.
3419 2003-03-24 Paul D. Smith <psmith@gnu.org>
3421 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3422 Upgrade to autoconf 2.57 and automake 1.7.3.
3424 * job.c: More OS/2 changes from Andreas Buening.
3426 * file.c (print_file): Fix variable initialization.
3429 * remake.c (notice_finished_file):
3431 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3432 some calls (like readdir()) return NULL in valid situations
3433 without resetting errno. Fixes bug #2846.
3435 2003-02-25 Paul D. Smith <psmith@gnu.org>
3437 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3439 * job.c (_is_unixy_shell) [OS/2]: New function.
3440 Set default shell to /bin/sh.
3441 (reap_children): Close the job_rfd pipe here since we don't use a
3443 (set_child_handler_action_flags): define this to empty on OS/2.
3444 (start_job_command): Close the jobserver pipe and use
3445 child_execute_job() instead of fork/exec.
3446 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3447 rather than exec'ing, then reconfigure stdin/stdout.
3448 (exec_command): Rewrite to use spawn instead of exec. Return the
3451 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3452 in DOS. Handle the TEMP environment variable as in DOS. Don't
3453 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3454 use -j in DOS mode. Use child_execute_job() instead of
3457 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3460 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3461 prototypes that return values.
3463 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3465 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3466 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3468 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3471 2003-02-24 Paul D. Smith <psmith@gnu.org>
3473 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3474 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3475 (child_execute_job) [VMS]: Handle error status properly.
3476 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3478 * function.c (func_shell): Use EINTRLOOP() while reading from the
3479 subshell pipe (Fixes bug #2502).
3480 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3482 * main.c (main): Ditto.
3484 2003-01-30 Paul D. Smith <psmith@gnu.org>
3486 * read.c (eval): eval() was not fully reentrant, because the
3487 collapsed buffer was static. Change it to be an automatic
3488 variable so that eval() can be invoked recursively.
3490 (eval): Apply patch # 1022: fix memory reference error on long
3491 target-specific variable lines.
3492 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3494 * function.c (check_numeric): Combine the is_numeric() function
3495 into this function, since it's only called from one place.
3496 Constify this function. Have it print the incorrect string in the
3497 error message. Fixes bug #2407.
3498 (strip_whitespace): Constify.
3499 (func_if): Constify.
3500 * expand.c (expand_argument): Constify.
3502 2003-01-29 Paul D. Smith <psmith@gnu.org>
3504 Fix bug # 2169, also reported by other people on various systems.
3506 * make.h: Some systems, such as Solaris and PTX, do not fully
3507 implement POSIX-compliant SA_RESTART functionality; important
3508 system calls like stat() and readdir() can still fail with EINTR
3509 even if SA_RESTART has been set on the signal handler. So,
3510 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3511 EINTR for system calls which return -1 or 0 (NULL), respectively,
3513 Also, remove the old atomic_stat()/atomic_readdir() and
3514 HAVE_BROKEN_RESTART handling.
3516 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3518 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3519 * remake.c (touch_file): Ditto.
3521 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3522 * read.c (construct_include_path): Ditto.
3523 * remake.c (name_mtime): Ditto.
3524 * vpath.c (selective_vpath_search): Ditto.
3525 * dir.c (find_directory): Ditto.
3526 (local_stat): Ditto.
3527 (find_directory): Use ENULLLOOP() to wrap opendir().
3528 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3530 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3531 atomic_readdir() handling.
3533 2003-01-22 Paul D. Smith <psmith@gnu.org>
3535 * function.c (func_call): Fix Bug #1744. If we're inside a
3536 recursive invocation of $(call ...), mask any of the outer
3537 invocation's arguments that aren't used by this one, so that this
3538 invocation doesn't "inherit" them accidentally.
3540 2002-12-05 Paul D. Smith <psmith@gnu.org>
3542 * function.c (subst_expand): Valery Khamenia reported a
3543 pathological performance hit when doing substitutions on very
3544 large values with lots of words: turns out we were invoking
3545 strlen() a ridiculous number of times. Instead of having each
3546 call to sindex() call strlen() again, keep track of how much of
3547 the text we've seen and pass the length to sindex().
3549 2002-11-19 Paul D. Smith <psmith@gnu.org>
3551 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3554 2002-11-16 Paul D. Smith <psmith@gnu.org>
3556 * NMakefile.template (OBJS): Add hash.c object file.
3557 * SMakefile.template (srcs): Ditto.
3558 * Makefile.ami (objs): Ditto.
3559 * build_w32.bat: Ditto.
3561 * Makefile.DOS.template: Remove extra dependencies.
3563 2002-10-25 Paul D. Smith <psmith@gnu.org>
3565 * expand.c (install_variable_buffer): New function. Install a new
3566 variable_buffer context and return the previous one.
3567 (restore_variable_buffer): New function. Free the current
3568 variable_buffer context and put a previously saved one back.
3569 * variable.h: Prototypes for {install,restore}_variable_buffer.
3570 * function.c (func_eval): Push a new variable_buffer context
3571 before we eval, then restore the old one when we're done.
3574 * read.c (install_conditionals): New function. Install a new
3575 conditional context and return the previous one.
3576 (restore_conditionals): New function. Free the current
3577 conditional context and put a previously saved one back.
3578 (eval): Use the {install,restore}_conditionals for "include"
3580 (eval_buffer): Use {install,restore}_conditionals to preserve the
3581 present conditional state before we evaluate the buffer.
3584 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3586 (Recursion): Add a variable index entry for CURDIR.
3588 * README.cvs: Update to appropriate versions.
3589 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3590 don't need to copy loadavg.c: automake is smart enough to create
3591 it for me. Still have a bug in automake related to ansi2knr tho.
3593 2002-10-14 Paul D. Smith <psmith@gnu.org>
3595 * remake.c (notice_finished_file): Only touch targets if they have
3596 at least one command (as per POSIX). Resolve Bug #1418.
3598 * *.c: Convert to using ANSI C-style function definitions.
3599 * Makefile.am: Enable the ansi2knr feature of automake.
3600 * configure.in: ditto.
3602 2002-10-13 Paul D. Smith <psmith@gnu.org>
3604 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3605 for automatic variable values like $^, etc. In the case of very
3606 large lists of prerequisites this causes problems. Instead reuse
3607 a static buffer (resizeable) for each variable.
3609 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3610 target-specific variable definitions. Check for it and set an
3612 (record_target_var): Set the export field to v_export if the
3613 "exported" flag is set.
3614 * doc/make.texi (Target-specific): Document the ability to use
3617 * doc/make.texi: Change the name of the section on automatic
3618 variables from "Automatic" to "Automatic Variables". Added text
3619 clarifying the scope of automatic variables.
3621 2002-10-04 Paul D. Smith <psmith@gnu.org>
3623 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3625 (record_files): Ditto.
3627 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3628 the search for the '=' to only within the enclosing parens.
3630 2002-10-03 Paul D. Smith <psmith@gnu.org>
3632 Version 3.80 released.
3634 * dir.c: Change hash functions to use K&R function definition style.
3635 * function.c: Ditto.
3637 * variable.c: Ditto.
3639 Update to automake 1.7.
3641 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3642 (pdf): Remove this target as automake now provides one.
3644 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3646 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3648 * makefile.com: Updates for GNU make 3.80.
3649 * makefile.vms: Ditto.
3651 2002-09-23 Paul D. Smith <psmith@gnu.org>
3653 * read.c (enum make_word_type): Remove w_comment.
3654 (get_next_mword): Don't treat comment characters as special; where
3655 this function is used we will never see a comment (it's stripped
3656 before we get here) and treating comments specially means that
3657 targets like "foo\#bar" aren't handled properly.
3659 2002-09-18 Paul D. Smith <psmith@gnu.org>
3661 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3663 * read.c (eval): Expansion of arguments to export/unexport was
3664 ignoring all arguments after the first one. Change the algorithm
3665 to expand the whole line once, then parse the results.
3667 2002-09-17 Paul D. Smith <psmith@gnu.org>
3669 Fix Bug #940 (plus another bug I found while looking at this):
3671 * read.c (record_target_var): enter_file() will add a new entry if
3672 it's a double-colon target: we don't want to do that in this
3673 situation. Invoke lookup_file() and only enter_file() if it does
3674 not already exist. If the file we get back is a double-colon then
3675 add this variable to the "root" double-colon target.
3677 * variable.c (initialize_file_variables): If this file is a
3678 double-colon target but is not the "root" target, then initialize
3679 the root and make the root's variable list the parent of our
3682 2002-09-13 Paul D. Smith <psmith@gnu.org>
3684 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3686 * hash.c (round_up_2): Get rid of a warning.
3688 2002-09-12 Paul D. Smith <psmith@gnu.org>
3690 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3691 so it doesn't complain about getloadavg.c.
3693 * commands.c (set_file_variables): Make sure we always alloca() at
3694 least 1 character for the value of $? (for '\0').
3696 2002-09-11 Paul D. Smith <psmith@gnu.org>
3698 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3699 macro to use RESULT instead of the incorrect _RESULT_.
3701 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3702 and atomic_readdir(). We need to #include dirent.h to get this to
3704 * misc.c (atomic_readdir): Fix typos.
3706 2002-09-10 Paul D. Smith <psmith@gnu.org>
3708 * read.c (eval): Expand variable lists given to export and
3709 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3710 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3712 * doc/make.texi (Variables/Recursion): Document this.
3713 (Conditional Syntax): And here.
3715 2002-09-09 Paul D. Smith <psmith@gnu.org>
3717 * configure.in: Check for memmove().
3719 2002-09-07 Paul D. Smith <psmith@gnu.org>
3721 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3722 Michael Sterrett <msterret@coat.com> reports that while it has
3723 SA_RESTART, it does not work properly.
3725 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3726 that invokes stat() and loops to do it again if it returns EINTR.
3727 (atomic_readdir): Ditto, with readdir().
3729 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3730 and readdir() to atomic_stat() and atomic_readdir().
3732 2002-09-04 Paul D. Smith <psmith@gnu.org>
3734 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3735 reports that GNU make sometimes doesn't recognize that targets can
3736 be made, when directories can be created as prerequisites. He
3737 reports that changing the order of predicates in the DEP->changed
3738 flag test so that lookup_file() is always performed, solves this
3741 2002-08-08 Paul D. Smith <psmith@gnu.org>
3743 * configure.in: Require a newer version of gettext.
3745 * misc.c (perror_with_name): Translate the format string (for
3746 right-to-left language support).
3747 (pfatal_with_name): Ditto.
3749 * main.c: Create a static array of strings to store the usage
3750 text. This is done to facilitate translations.
3751 (struct command_switch): Remove argdesc and description fields.
3752 (switches): Remove values for obsolete fields.
3753 (print_usage): Print each element of the usage array.
3755 * hash.c: Change function definitions to be K&R style.
3757 2002-08-02 Paul D. Smith <psmith@gnu.org>
3759 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3760 this one because it's too hard to get right. We'll look at it for
3762 * main.c (main): Don't create the .TARGETS variable.
3763 * variable.c (handle_special_var): Don't handle .TARGETS.
3765 2002-08-01 Paul D. Smith <psmith@gnu.org>
3767 * main.c (switches): Add a new option, -B (--always-make). If
3768 specified, make will rebuild all targets that it encounters even
3769 if they don't appear to be out of date.
3770 (always_make_flag): New flag.
3771 * make.h: Extern always_make_flag.
3772 * remake.c (update_file_1): Check always_make_flag; if it's set we
3773 will always rebuild any target we can, even if none of its
3774 prerequisites are newer.
3777 * doc/make.texi (Shell Function): Make it clear that make
3778 variables marked as "export" are not passed to instances of the
3781 Add new introspection variable .VARIABLES and .TARGETS.
3783 * variable.c (handle_special_var): New function. If the variable
3784 reference passed in is "special" (.VARIABLES or .TARGETS),
3785 calculate the new value if necessary. .VARIABLES is handled here:
3786 walk through the hash of defined variables and construct a value
3787 which is a list of the names. .TARGETS is handled by
3788 build_target_list().
3789 (lookup_variable): Invoke handle_special_var().
3790 * file.c (build_target_list): Walk through the hask of known files
3791 and construct a list of the names of all the ones marked as
3793 * main.c (main): Initialize them to empty (and as simple variables).
3794 * doc/make.texi (Special Variables): Document them.
3795 * NEWS: Mention them.
3797 * variable.h (struct variable): Add a new flag "exportable" which
3798 is true if the variable name is valid for export.
3799 * variable.c (define_variable_in_set): Set "exportable" when a new
3800 variable is defined.
3801 (target_environment): Use the "exportable" flag instead of
3802 re-checking the name here... an efficiency improvement.
3804 2002-07-31 Paul D. Smith <psmith@gnu.org>
3806 * config.h-vms.template: Updates to build on VMS. Thanks to
3807 Brian_Benning@aksteel.com for helping verify the build.
3808 * makefile.com: Build the new hash.c file.
3809 * hash.h: Use strcpmi(), not stricmp(), in the
3810 HAVE_CASE_INSENSITIVE_FS case.
3812 2002-07-30 Paul D. Smith <psmith@gnu.org>
3814 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3815 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3816 Reported by <Brian_Benning@aksteel.com>.
3818 2002-07-10 Paul D. Smith <psmith@gnu.org>
3820 * variable.c (pop_variable_scope): Remove variable made unused by
3821 new hash infrastructure.
3822 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3823 comparisons as well as name comparisons.
3824 * variable.h: Add a prototype for new hash_init_function_table().
3825 * file.c (lookup_file): Remove variables made unused by new hash
3827 * dir.c (directory_contents_hash_2): Missing return of hash value.
3828 (dir_contents_file_exists_p): Remove variables made unused by new
3829 hash infrastructure.
3832 Installed Greg McGary's integration of the hash functions from the
3833 GNU id-utils package:
3835 2002-07-10 Greg McGary <greg@mcgary.org>
3837 * scripts/functions/filter-out: Add literals to to the
3838 pattern space in order to add complexity, and trigger
3839 use of an internal hash table. Fix documentation strings.
3840 * scripts/targets/INTERMEDIATE: Reverse order of files
3841 passed to expected `rm' command.
3843 2002-07-10 Greg McGary <greg@mcgary.org>

3935 2002-07-10 Paul D. Smith <psmith@gnu.org>
3937 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3938 prerequisite list. A real SysV make will expand the entire
3939 prerequisites list _twice_: we don't do that as it's a big
3940 backward-compatibility problem. We only replace those specific
3943 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3944 references left in the list of prerequisites. Check for .POSIX as
3945 we record targets, so we can disable non-POSIX behavior while
3946 reading makefiles as well as running them.
3947 (eval): Check the prerequisite list to see if we have anything
3948 that looks like a SysV prerequisite variable reference.
3950 2002-07-09 Paul D. Smith <psmith@gnu.org>
3952 * doc/make.texi (Prerequisite Types): Add a new section describing
3953 order-only prerequisites.
3955 * read.c (uniquize_deps): If we have the same file as both a
3956 normal and order-only prereq, get rid of the order-only prereq,
3957 since the normal one supersedes it.
3959 2002-07-08 Paul D. Smith <psmith@gnu.org>
3961 * AUTHORS: Added Greg McGary to the AUTHORS file.
3962 * NEWS: Blurbed order-only prerequisites.
3963 * file.c (print_file): Show order-only deps properly when printing
3966 * maintMakefile: Add "update" targets for wget'ing the latest
3967 versions of various external files. Taken from Makefile.maint in
3970 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3971 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3973 2002-07-07 Paul D. Smith <psmith@gnu.org>
3975 * po/*.po: Remove. We'll use wget to retrieve them at release
3978 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3979 rather than a shell you get an exception. Make sure we look up
3980 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3982 * remake.c (notice_finished_file): Fix handling of -t flag.
3983 Patch provided by Henning Makholm <henning@makholm.net>.
3985 * implicit.c (pattern_search): Some systems apparently run short
3986 of stack space, and using alloca() in this function caused an
3987 overrun. I modified it to use xmalloc() on the two variables
3988 which seemed like they might get large. Fixes Bug #476.
3990 * main.c (print_version): Update copyright notice to conform with
3992 (print_usage): Update help output.
3994 * function.c (func_eval): Create a new make function, $(eval
3995 ...). Expand the arguments, put them into a buffer, then invoke
3996 eval_buffer() on the resulting string.
3997 (func_quote): Create a new function, $(quote VARNAME). Inserts
3998 the value of the variable VARNAME without expanding it any
4001 * read.c (struct ebuffer): Change the linebuffer structure to an
4002 "eval buffer", which can be either a file or a buffer.
4003 (eval_makefile): Move the code in the old read_makefile() which
4004 located a makefile into here: create a struct ebuffer with that
4005 information. Have it invoke the new function eval() with that
4007 (eval_buffer): Create a new function that creates a struct ebuffer
4008 that holds a string buffer instead of a file. Have it invoke
4009 eval() with that ebuffer.
4010 (eval): New function that contains the guts of the old
4011 read_makefile() function: this function parses makefiles. Obtains
4012 data to parse from the provided ebuffer. Some modifications to
4013 make the flow of the function cleaner and clearer. Still could
4014 use some work here...
4015 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
4016 contents of the define/endef variable from the ebuffer.
4017 (readstring): Read the next line from a string-style ebuffer.
4018 (readline): Read the next line from an ebuffer. If it's a string
4019 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
4022 * dep.h (eval_buffer): Prototype eval_buffer();
4024 * variable.c (do_variable_definition): Make sure that all
4025 non-target-specific variables are registered in the global set.
4026 If we're invoked from an $(eval ...) we might be inside a $(call
4027 ...) or other function which has pushed a variable scope; we still
4028 want to define our variables from evaluated makefile code in the
4031 2002-07-03 Greg McGary <greg@mcgary.org>
4033 * dep.h (struct dep) [ignore_mtime]: New member.
4034 [changed]: convert to a bitfield.
4035 * implicit.c (pattern_search): Zero ignore_mtime.
4036 * main.c (main, handle_non_switch_argument): Likewise.
4037 * rule.c (convert_suffix_rule): Likewise.
4038 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
4039 (read_makefile): Parse '|' in prerequisite list.
4040 (uniquize_deps): Consider ignore_mtime when comparing deps.
4041 * remake.c (update_file_1, check_dep): Don't force remake for
4042 dependencies that have d->ignore_mtime.
4043 * commands.c (FILE_LIST_SEPARATOR): New constant.
4044 (set_file_variables): Don't include a
4045 prerequisite in $+, $^ or $? if d->ignore_mtime.
4048 2002-06-18 Paul D. Smith <psmith@gnu.org>
4050 * make.texinfo: Updates for next revision. New date/rev/etc.
4051 Recreate all Info menus. Change license on the manual to the GNU
4052 Free Documentation License. A number of typos.
4053 (Variables Simplify): Don't use "-" before it's defined.
4054 (Automatic Prerequisites): Rewrite the target example to work
4055 properly if the compile fails. Remove incorrect comments about
4056 how "set -e" behaves.
4057 (Text Functions): Move the "word", "wordlist", "words", and
4058 "firstword" functions here, from "File Name Functions".
4059 * make-stds.texi: Update from latest GNU version.
4060 * fdl.texi: (created) Import the latest GNU version.
4062 2002-06-06 Paul D. Smith <psmith@gnu.org>
4064 * variable.c (do_variable_definition): New function: extract the
4065 part of try_variable_definition() that actually sets the value
4066 into a separate function.
4067 (try_variable_definition): Call do_variable_definition() after
4068 parsing the variable definition string.
4069 (define_variable_in_set): Make the name argument const.
4071 * variable.h (enum variable_flavor): Make public.
4072 (do_variable_definition): Create prototype.
4074 * read.c (read_all_makefiles): Create a new built-in variable,
4076 (read_makefile): Add each makefile read in to this variable value.
4078 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4080 * Makefile.DOS.template: Tweak according to changes in the
4081 distribution. Add back the dependencies of *.o files.
4083 * configh.dos.template: Synchronize with config.h.in.
4085 2002-05-09 Paul D. Smith <psmith@gnu.org>
4087 * file.c (file_timestamp_now): Use K&R function declaration.
4089 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4090 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4091 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4092 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4093 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4094 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4095 nlist.n_name is a pointer rather than an array.
4097 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4098 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4099 * configure.in: Use it instead of the old version.
4101 * main.c (main): Prefer setvbuf() to setlinebuf().
4103 2002-05-08 Paul D. Smith <psmith@gnu.org>
4105 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4106 (loadavg_LDADD): Ditto.
4108 2002-04-29 Paul D. Smith <psmith@gnu.org>
4110 * expand.c (recursively_expand_for_file): Rename
4111 recursively_expand() to recursively_expand_for_file() and provide
4112 an extra argument, struct file. If the argument is provided, set
4113 the variable scope to that of the file before expanding.
4114 * variable.h (recursively_expand): Make this a macro that invokes
4115 recursively_expand_for_file() with a NULL file pointer.
4116 * variable.c (target_environment): Call the renamed function and
4117 provide the current file context.
4118 Fixes Debian bug #144306.
4120 2002-04-28 Paul D. Smith <psmith@gnu.org>
4122 Allow $(call ...) user-defined variables to be self-referencing
4123 without throwing an error. Allows implementation of transitive
4124 closures, among other possibly useful things.
4125 Requested by: Philip Guenther <guenther@sendmail.com>
4127 * variable.h (struct variable): Add a new field: exp_count, and
4128 new macros to hold its size and maximum value.
4129 (warn_undefined): Make this a macro.
4130 * variable.c (define_variable_in_set): Initialize it.
4131 * expand.c (recursively_expand): If we detect recursive expansion
4132 of a variable, check the exp_count field. If it's greater than 0
4133 allow the recursion and decrement the count.
4134 (warn_undefined): Remove this (now a macro in variable.h).
4135 * function.c (func_call): Before we expand the user-defined
4136 function, modify its exp_count field to contain the maximum
4137 number of recursive calls we'll allow. After the call, reset it
4140 2002-04-21 Paul D. Smith <psmith@gnu.org>
4142 Modified to use latest autoconf (2.53), automake (1.6.1), and
4143 gettext (0.11.1). We're using gettext's new "external" support,
4144 to avoid including libintl source with GNU make.
4146 * README.cvs: New file. Explain how to build GNU make from CVS.
4148 * configure.in: Modify checking for the system glob library.
4149 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4150 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4151 etc. will manage it correctly). Set an automake conditional
4152 USE_LOCAL_GLOB to decide whether to compile the glob library.
4154 * getloadavg.c (main): Include make.h in the "TEST" program to
4157 * Makefile.am: Remove special rules for loadavg. Replace them
4158 with Automake capabilities for building extra programs.
4160 * signame.c: This file does nothing if the system provide
4161 strsignal(). If not, it implements strsignal(). If the system
4162 doesn't define sys_siglist, then we make our own; otherwise we use
4164 * signame.h: Removed.
4166 * main.c (main): No need to invoke signame_init(). Update copyright.
4168 * ABOUT-NLS: Removed.
4169 * gettext.c: Removed.
4170 * gettext.h: Get a simplified copy from the gettext package.
4172 * i18n/*.po: Moved to po/.
4175 * config/*: Created. Contains package configuration helper files.
4176 * config.guess, config.sub: Moved to config directory.
4178 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4179 Rework to use new-style autoconf features. Use the "external"
4180 mode for gettext. Make the build.sh config file conditional on
4181 whether build.sh.in exists, to avoid autoconf errors.
4182 * acinclude.m4: Removed almost all macros as being obsolete.
4183 Rewrote remaining macros to use AC_DEFINE.
4184 * acconfig.h: Removed.
4186 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4187 conditional to handle customs support. Remove special handling
4190 2002-04-20 Paul D. Smith <psmith@gnu.org>
4192 * function.c (func_call): Don't mark the argument variables $1,
4193 etc. as recursive. They've already been fully expanded so
4194 there's no need to do it again, and doing so strips escaped $'s.
4195 Reported by Sebastian Glita <glseba@yahoo.com>.
4197 * remake.c (notice_finished_file): Walk through double-colon
4198 entries via the prev field, not the next field!
4199 Reported by Greg McGary <greg@mcgary.org>.
4201 * main.c (main): If the user specifies -q and asks for a specific
4202 target which is a makefile, we got an assert. In that case it
4203 turns out we should continue normally instead.
4205 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4207 * i18n/he.po: Installed a new translation.
4209 2002-01-07 Paul D. Smith <psmith@gnu.org>
4211 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4213 2001-12-04 Paul D. Smith <psmith@gnu.org>
4215 * i18n/ja.po: Installed an updated translation.
4217 2001-09-06 Paul Eggert <eggert@twinsun.com>
4219 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4220 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4222 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4224 (main): Get rid of any avoidable limit on stack size.
4226 2001-09-04 Paul D. Smith <psmith@gnu.org>
4228 * i18n/da.po: Installed an updated translation.
4230 2001-08-03 Paul D. Smith <psmith@gnu.org>
4232 * i18n/fr.po: Installed an updated translation.
4233 Resolves Debian bug #106720.
4235 2001-06-13 Paul D. Smith <psmith@gnu.org>
4237 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4240 2001-06-11 Paul D. Smith <psmith@gnu.org>
4242 * i18n/ko.po: Installed a new translation.
4244 2001-05-06 Paul D. Smith <psmith@gnu.org>
4246 Modify the EINTR handling.
4248 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4249 the way in which we manage the file descriptor/signal handler race
4250 trap to be more efficient.
4252 2001-05-06 Paul Eggert <eggert@twinsun.com>
4254 Restart almost all system calls that are interrupted, instead
4255 of worrying about EINTR. The lone exception is the read() for
4258 * configure.in (HAVE_SA_RESTART): New macro.
4259 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4260 * main.c (main): Use SA_RESTART instead of the old,
4261 nonstandard SA_INTERRUPT.
4263 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4264 * main.c (bsd_signal): New function or macro,
4265 if the implementation doesn't supply it.
4266 (The bsd_signal function will be in POSIX 1003.1-200x.)
4267 (HANDLESIG): Remove.
4268 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4270 * make.h (EINTR_SET): Remove.
4271 (SA_RESTART): New macro.
4273 * arscan.c (ar_member_touch): Don't worry about EINTR.
4274 * function.c (func_shell): Likewise.
4275 * job.c (reap_children, free_child, new_job): Likewise.
4276 * main.c (main): Likewise.
4277 * remake.c (touch_file, name_mtime): Likewise.
4279 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4280 if fstat failed with errno!=EINTR, the error was ignored.
4282 * job.c (set_child_handler_action_flags): New function.
4283 (new_job): Use it to temporarily clear the SIGCHLD action flags
4284 while reading the token.
4286 2001-05-02 Paul D. Smith <psmith@gnu.org>
4288 * job.c (start_job_command): Don't add define/endef per-line flags
4289 to the top-level flags setting.
4291 2001-04-03 Paul D. Smith <psmith@gnu.org>
4293 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4294 bit on error, so check for odd return values, not non-0 return
4296 (VMS_get_member_info): Calculate the timezone differences correctly.
4297 Reported by John Fowler <jfowler@nyx.net>.
4300 2001-03-14 Paul D. Smith <psmith@gnu.org>
4302 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4303 value before invoking define_variable().
4304 Reported by John Fowler <jfowler@nyx.net>.
4306 2001-02-07 Paul D. Smith <psmith@gnu.org>
4308 * read.c (record_target_var): If we reset the variable due to a
4309 command-line variable setting overriding it, turn off the "append"
4312 2001-01-17 Paul D. Smith <psmith@gnu.org>
4314 * variable.c (lookup_variable) [VMS]: When getting values from the
4315 environment, allocate enough space for the _value_ plus escapes,
4316 not enough space for the name plus escapes :-/.
4317 Reported by John Fowler <jfowler@nyx.net>.
4319 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4320 warnings that make generates, so it doesn't look like an error.
4321 Reported by Karl Berry <karl@gnu.org>.
4324 Fix for PR/2020: Rework appended target-specific variables. I'm
4325 fairly confident this algorithm is finally correct.
4327 * expand.c (allocated_variable_append): Rewrite. Instead of
4328 expanding each appended variable then adding all the expanded
4329 strings together, we append all the unexpanded values going up
4330 through the variable set contexts, then expand the final result.
4331 This behaves just like non-target-specific appended variable
4332 values, while the old way didn't in various corner cases.
4333 (variable_append): New function: recursively append the unexpanded
4334 value of a variable, walking from the outermost variable scope to
4336 * variable.c (lookup_variable): Remove the code that looked up the
4337 variable set list if the found variable was "append". We don't
4339 (lookup_variable_in_set): Make this non-static so we can use it
4341 (try_variable_definition): Use lookup_variable_in_set() rather
4342 than faking out current_variable_set_list by hand (cleanup).
4343 * variable.h: Add a prototype for the now non-static
4344 lookup_variable_in_set().
4346 2000-11-17 Paul D. Smith <psmith@gnu.org>
4348 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4349 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4350 before throwing a fit.
4352 2000-11-17 Paul D. Smith <psmith@gnu.org>
4354 * read.c (readline): CRLF calculations had a hole, if you hit the
4355 buffer grow scenario just right. Reworked the algorithm to avoid
4356 the need for len or lastlen at all. Problem description with
4357 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4359 2000-10-24 Paul D. Smith <psmith@gnu.org>
4361 * gettext.c (SWAP): Declare this with the prototype, otherwise
4362 some systems don't work (non-32-bit? Reported for Cray T3E).
4363 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4365 2000-10-05 Paul D. Smith <psmith@gnu.org>
4367 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4368 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4370 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4372 2000-09-22 Paul D. Smith <psmith@gnu.org>
4374 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4375 parts of the real gettext.h here, and we expect to really include
4376 the real gettext.h later. If we keep this #define, it's ignored.
4378 2000-09-21 Paul D. Smith <psmith@gnu.org>
4380 * main.c (log_working_directory): Rework the text to use complete
4381 sentences, to make life simpler for the translators.
4383 2000-08-29 Paul D. Smith <psmith@gnu.org>
4385 * file.c (remove_intermediates): Print a debug message before we
4386 remove intermediate files, so the user (if she uses -d) knows
4389 2000-08-21 Paul D. Smith <psmith@gnu.org>
4391 * variable.c (try_variable_definition): Change how we handle
4392 target-specific append variable defns: instead of just setting the
4393 value, expand it as an append _but_ only within the current
4394 target's context. Otherwise we lose all but the last value if the
4395 variable is appended more than once within the current target
4396 context. Fixes PR/1831.
4398 2000-08-16 Paul D. Smith <psmith@gnu.org>
4400 * function.c (func_shell): Nul-terminate the buffer before
4401 printing an exec error message (just in case it's not!).
4402 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4404 2000-07-25 Paul D. Smith <psmith@gnu.org>
4406 * job.c (construct_command_argv_internal): Add "~" to the list of
4407 sh_chars[] which disallow optimizing out the shell call.
4409 2000-07-23 Paul Eggert <eggert@twinsun.com>
4411 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4412 supersedes --disable-nsec-timestamps.
4413 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4414 * README: Remove --disable-nsec-timestamps.
4416 * filedef.h (struct file.low_resolution_time): New member.
4417 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4418 * remake.c (update_file_1):
4419 Avoid spurious rebuilds due to low resolution time stamps,
4420 generalizing the earlier code that applied only to archive members.
4421 (f_mtime): Archive members always have low resolution time stamps.
4423 * configure.in: Remove --disable-nsec-timestamps, as this has
4424 been superseded by .LOW_RESOLUTION_TIME.
4426 2000-07-23 Paul Eggert <eggert@twinsun.com>
4428 * configure.in (enable_nsec_timestamps): Renamed from
4429 make_cv_nsec_timestamps, since enable/disable options
4430 shouldn't be cached.
4432 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4433 and Paul Eggert <eggert@twinsun.com>
4435 * file.c (file_timestamp_now):
4436 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4437 so that clock_gettime is not linked unless needed.
4439 * filedef.h (FILE_TIMESTAMP_HI_RES):
4440 Remove definition; "configure" now does this.
4442 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4443 to before high resolution file timestamp check,
4444 since that check now uses uintmax_t.
4445 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4446 high resolution file timestamps.
4447 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4448 so that we don't link in clock_gettime unnecessarily.
4450 2000-07-17 Paul D. Smith <psmith@gnu.org>
4452 * i18n/ja.po: New version of the translation file.
4454 2000-07-07 Paul D. Smith <psmith@gnu.org>
4456 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4457 the offset calculation.
4458 (name_mtime): Replace EINTR test with EINTR_SET macro.
4460 2000-07-07 Paul Eggert <eggert@twinsun.com>
4464 * remake.c (update_file_1):
4465 Avoid spurious rebuilds of archive members due to their
4466 timestamp resolution being only one second.
4467 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4468 the clock's resolution being lower than file timestamps'.
4469 When warning about future timestamps, report only the discrepancy,
4470 not the absolute value of the timestamp and the current time.
4472 * file.c (file_timestamp_now): New arg RESOLUTION.
4473 * filedef.h (file_timestamp_now): Likewise.
4474 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4476 2000-07-05 Paul D. Smith <psmith@gnu.org>
4478 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4479 to listp. Fixes PR/1793.
4481 2000-06-26 Paul Eggert <eggert@twinsun.com>
4483 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4485 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4487 * remake.c (f_mtime): Remove unused var memtime.
4489 2000-06-25 Martin Buchholz <martin@xemacs.org>
4491 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4492 Ran spell-check on make.texinfo.
4494 2000-06-23 Paul D. Smith <psmith@gnu.org>
4496 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4497 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4498 * make.h: Define these macros.
4500 * Version 3.79.1 released.
4502 * configure.in: Add a new option, --disable-nsec-timestamps, to
4503 avoid using sub-second timestamps on systems that support it. It
4504 can lead to problems, e.g. if your makefile relies on "cp -p".
4505 * README.template: Document the issue with "cp -p".
4507 * config.guess, config.sub: Updated.
