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

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

842 2009-10-03 Paul Smith <psmith@gnu.org>
844 * make.h: Include <alloca.h> even on systems where __GNUC__ is

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

926 (make_1.html): Removed.
927 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
928 (all-recursive): Allow for more than one subdir in the build
930 (mostlyclean-recursive, clean-recursive, distclean-recursive)
931 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
932 (tags-recursive): Allow for more than one subdir in the build
934 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
935 targets. Enter into doc/ to produce the targets.
936 (all-am): $(INFO_DEPS) replaced by info.
938 2009-09-26 Paul Smith <psmith@gnu.org>
940 * read.c (record_files): Use free_ns() to free struct nameseq.
943 * rule.c (freerule): Use free_dep_chain().
945 * read.c (record_files): Free FILENAMES chain for implicit rules.
946 (eval): Static pattern targets go into the string cache.
948 * function.c (string_glob): Free NAME in the nameseq chain.
950 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
952 * implicit.c (pattern_search): Terminate early if we haven't
953 found any rules to try (performance improvement).
955 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
957 * implicit.c (pattern_search): Merge three parallel arrays,
958 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
959 of struct TRYRULE. In the old version the latter two arrays
960 had insufficient length.
962 2009-09-24 Paul Smith <psmith@gnu.org>
964 * implicit.c (pattern_search): Add back support for order-only
965 prerequisites for secondary expansion implicit rules, that were
966 accidentally dropped. If we find a "|", enable order-only mode
967 and set IGNORE_MTIME on all deps that are seen afterward.
968 (pattern_search): Fix memory leaks: for intermediate files where
969 we've already set the file variable and pattern variable sets, be
970 sure to either save or free them as appropriate.
972 2009-09-23 Paul Smith <psmith@gnu.org>
974 Rework the way secondary expansion is stored, for efficiency.
975 This changes secondary expansion so that ONLY WHEN we know we have
976 a possibility of needing secondary expansion, do we defer the
977 secondary expansion. This means more parsing the deps but we use
978 a lot less memory (due to the strcache). Also, this fixes
981 * read.c (eval): Don't parse the dep string here anymore.
982 (record_files): Take the dep argument as an unparsed string. If
983 secondary expansion is enabled AND the prereq string has a '$' in
984 it, then set NEED_2ND_EXPANSION and keep the entire string.
985 Otherwise, parse the dep string here to construct the dep list
986 with the names in the strcache.
988 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
989 duplicate the name string (others are in the strcache).
991 * implicit.c: Remove struct idep and free_idep_chain(): unused.
992 (struct patdeps): New structure to store prereq information.
993 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
994 which prerequisites need expansion, and expand only those.
996 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
997 and enter_prereqs(). split_prereqs() takes a fully-expanded string
998 and splits it into a DEP list, handling order-only prereqs.
999 (enter_prereqs): This function enters a list of DEPs into the file
1000 database. If there's a stem defined, expand any pattern chars.
1001 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
1002 set. Use the above functions.
1003 (snap_deps): Only perform second expansion on prereqs that need it,
1004 as defined by the NEED_2ND_EXPANSION flag.
1005 (print_prereqs): New function to print the prereqs
1006 (print_file): Call print_prereqs() rather than print inline.
1008 * hash.h (STRING_COMPARE): Take advantage of strcache() by
1010 (STRING_N_COMPARE): Ditto.
1011 (ISTRING_COMPARE): Ditto.
1013 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
1014 (parse_file_seq): Return void*
1015 * read.c (parse_file_seq): Return void*.
1016 (eval): Invoke macroized version of parse_file_seq()
1017 * default.c (set_default_suffixes): Ditto.
1018 * file.c (split_prereqs): Ditto.
1019 * function.c (string_glob): Ditto.
1020 * main.c (main): Ditto.
1021 * rule.c (install_pattern_rule): Ditto.
1023 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
1025 2009-09-16 Paul Smith <psmith@gnu.org>
1027 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
1029 * dep.h: Create alloc_dep() / free_dep() macros.
1031 * implicit.c (pattern_search): Take advantage of the new
1032 parse_file_seq() to add the directory prefix to each prereq.
1034 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
1035 all. Avoid reversing chains. Support adding prefixes.
1036 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
1037 cached/non-cached results.
1038 (eval): Remove multi_glob() & invoke new parse_file_seq().
1039 * rule.c (install_pattern_rule): Ditto.
1040 * main.c (main): Ditto.
1041 * implicit.c (pattern_search): Ditto.
1042 * function.c (string_glob): Ditto.
1043 * file.c (parse_prereqs): Ditto.
1044 * default.c (set_default_suffixes): Ditto.
1046 * variable.c (parse_variable_definition): Don't run off the end of
1047 the string if it ends in whitespace (found with valgrind).
1049 * commands.c (set_file_variables): Keep space for all targets in
1050 $? if -B is given (found with valgrind).
1052 2009-09-15 Paul Smith <psmith@gnu.org>
1054 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
1055 (xcalloc): Add new function.
1056 * make.h: New declarations.
1058 * ar.c (ar_glob_match): New calling method for concat().
1059 * main.c (main): Ditto.

1061 * read.c (eval_makefile): Ditto.
1062 (tilde_expand): Ditto.
1063 (parse_file_seq): Ditto.
1064 * variable.c (target_environment): Ditto.
1065 (sync_Path_environment): Ditto.
1067 * ar.c (ar_glob_match): Use xcalloc().
1068 * dir.c (file_impossible): Ditto.
1069 * file.c (enter_file): Ditto.
1070 * job.c (new_job): Ditto.
1071 * read.c (parse_file_seq): Ditto.
1072 * vmsfunctions.c (opendir): Ditto.
1074 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
1076 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
1077 inside the loop that looks up environment for PATH.
1079 2009-08-31 Eli Zaretskii <eliz@gnu.org>
1081 * function.c (windows32_openpipe): Update envp after calling
1082 sync_Path_environment.
1084 2009-08-02 Paul Smith <psmith@gnu.org>
1086 * remake.c (notice_finished_file): Ensure file->cmds is not null
1087 before looping through them. Fixes Savannah bug #21824.
1089 * doc/make.texi (Wildcard Examples): Clarify when objects is
1090 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1091 (Include): Clarify the behavior of -include.
1092 Fixes Savannah bug #18963.
1094 2009-08-01 Paul Smith <psmith@gnu.org>
1096 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1097 etc. come on the command line. Fixes Savannah bug #27093.
1099 * expand.c (expand_argument): If the argument is large enough use
1100 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1102 * variable.c (do_variable_definition): Avoid using alloca() to
1103 hold values, which can be large. Fixes Savannah bug #23960.
1105 * job.c (new_job): Use memmove() instead of strcpy() since both
1106 pointers are in the same memory block. Fixes Savannah bug #27148.
1107 Patch by Petr Machata.
1109 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1111 * job.c (construct_command_argv_internal): Add "ulimit" and
1112 "unset" to the sh_cmds for Unixy shells.
1114 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1116 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1117 that set make_cv_sys_gnu_glob, so they are also correctly set
1118 when the cache has been populated before.
1120 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1122 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1123 exist, as realpath(3) does where it's supported.
1125 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1127 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1128 (abspath): Support systems that define HAVE_DOS_PATHS (have
1129 drive letters in their file names). Use IS_PATHSEP instead of a
1130 literal '/' comparison. Fixes Savannah bug #26886.
1132 2009-06-14 Paul Smith <psmith@gnu.org>
1134 * remake.c (update_file_1): Remember the original file we marked
1135 as updating, so we can clear that flag again. If we find a target
1136 via vpath, FILE might change.
1137 (check_dep): Ditto. Fixes Savannah bug #13529.
1138 Patch by Reid Madsen <reid.madsen@tek.com>.
1140 2009-06-13 Paul Smith <psmith@gnu.org>
1142 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1143 included by MAKEFILES cannot give default goals.
1144 * read.c (eval): If set_default is not set, pass the no-default-goal
1145 value when we read included makefiles. Fixes Savannah bug #13401.
1147 * ar.c (ar_name): Ensure that targets with empty parens aren't
1148 considered archive member references: archive members must have a
1149 non-empty "member" string. Fixes Savannah bug #18435.
1151 * function.c (string_glob): Rely on multi_glob() to determine
1152 whether files exist or not. Remove call to file_exists_p() which
1153 is not always correct. Fixes Savannah bug #21231.
1154 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1155 then only files that really exist will be returned.
1156 * dep.h: Add new argument to multi_glob().
1157 * rule.c (install_pattern_rule): Ditto.
1158 * read.c (eval): Ditto.
1159 * main.c (main): Ditto.
1160 * implicit.c (pattern_search): Ditto.
1161 * file.c (parse_prereqs): Ditto.
1162 * default.c (set_default_suffixes): Ditto.
1164 2009-06-09 Paul Smith <psmith@gnu.org>
1166 * commands.c (set_file_variables): If always_make_flag is set,
1167 always add the prereq to $?. Fixes Savannah bug #17825.
1169 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1170 to rebuild the deps of all the also_make targets for that file.
1171 Fixes Savannah bug #19108.
1173 * implicit.c (pattern_search): Undo test for is_target, added by
1174 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1175 Rule Search Algorithm". Fixes Savannah bug #17752.
1177 * main.c (clean_jobserver): Clear the jobserver_fds options and
1178 set job_slots to the default when we clean up.
1179 (define_makeflags): Return the new MAKEFLAGS value.
1180 (main): Reset MAKEFLAGS in the environment when we re-exec.
1181 Fixes Savannah bug #18124.
1183 2009-06-08 Paul Smith <psmith@gnu.org>
1185 * read.c (eval): Collapse continuations post-semicolon on target-
1186 specific variables. Fixes Savannah bug #17521.
1188 2009-06-07 Paul Smith <psmith@gnu.org>
1190 * job.c (reap_children): For older systems without waitpid() (are
1191 there any of these left?) run wait(2) inside EINTRLOOP to handle
1192 EINTR errors. Fixes Savannah bug #16401.
1194 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1196 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1198 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1199 not the end, to catch second expansion $(eval ...) defining new
1200 target/prereq relationships during snap_deps.
1201 Fixes Savannah bug #24622.
1203 * read.c (record_files): The second-expansion "f->updating" hack
1204 was not completely correct: if assumed that the target with
1205 commands always had prerequisites; if one didn't then the ordering
1206 was messed up. Fixed for now to use f->updating to decide whether
1207 to preserve the last element in the deps list... but this whole
1208 area of constructing and reversing the deps list is too confusing
1209 and needs to be reworked. Fixes Savannah bug #21198.
1211 2009-06-06 Paul Smith <psmith@gnu.org>
1213 * hash.c (hash_insert): Remove useless test for NULL.
1214 Fixes Savannah bug #21823.
1216 * make.h: Move SET_STACK_SIZE determination to make.h.
1217 * main.c (main): New global variable, STACK_LIMIT, holds the
1218 original stack limit when make was started.
1219 * job.c (start_job_command): Reset the stack limit, if we changed it.
1220 Fixes Savannah bug #22010.
1222 * remake.c (check_dep): Only set the target's state to not-started
1223 if it's not already running. Found this while testing -j10 builds
1224 of glibc: various targets were being rebuilt multiple times.
1225 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1228 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1229 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1232 2009-06-04 Paul Smith <psmith@gnu.org>
1234 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1236 * maintMakefile: Modify access of config and gnulib Savannah
1237 modules to use GIT instead of CVS.
1239 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1240 Fixes Savannah bug #24655.
1242 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1243 this can happen during some invocations of $(eval ...) for example.
1244 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1246 2009-06-02 Paul Smith <psmith@gnu.org>
1248 * configure.in: Check for fileno()
1249 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1250 for the makefile file so invocations of $(shell ...) don't inherit it.
1251 Fixes Savannah bug #24277.
1253 2009-06-01 Paul Smith <psmith@gnu.org>
1255 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1256 expansion was handled incorrectly. Rework the default goal
1257 handling to save the variable only. Remove default_goal_file and
1259 * read.c (eval): Check default_goal_var, not default_goal_name.
1260 * read.c (record_target_var): Don't check default_goal_file here.
1262 2009-05-31 Paul Smith <psmith@gnu.org>
1264 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1265 it, and if the multi_glob() returns nothing (say it expanded to
1266 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1268 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1269 $(and ..) to the reference. Fixes Savannah bug #25694.
1271 * make.1: Be clear that some recipes will be executed even with -n.
1272 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1274 * doc/make.texi (Override Directive): Make more clear how
1275 overrides and appends interact.
1276 Elucidates part of Savannah bug #26207.
1278 * read.c (record_target_var): Don't reset the origin on
1279 target-specific variables; try_variable_definition() will handle
1280 this correctly. Fixes Savannah bug #26207.
1282 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1283 Fixes Savannah bug #25712.
1285 * implicit.c (pattern_search): Keep a pointer to the beginning of
1286 the filename and save that instead of the constructed pointer.
1287 Fixes Savannah bug #26593.
1288 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1290 2009-05-30 Paul Smith <psmith@gnu.org>
1292 * doc/make.texi (Multi-Line): Add a description of the new abilities
1293 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1294 "command sequence" vs. "recipe" syntax.
1295 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1296 after a define, to create variables with those flavors.
1298 2009-05-25 Paul Smith <psmith@gnu.org>
1300 Reworked the parser for variable assignments to allow multiple
1301 modifiers, and in any order. Also allows variable and
1302 prerequisites to be modifier names ('export', 'private', etc.)
1304 * NEWS: Add notes about user-visible changes.
1306 * read.c (struct vmodifiers): Remember what modifiers were seen.
1307 (parse_var_assignment): New function to parse variable assignments.
1308 (eval): Call the new function. Handle variable assignments earlier.
1310 * variable.c (parse_variable_definition): Only parse; don't create var.
1311 (assign_variable_definition): Call parse, then create the var.
1313 2009-05-24 Paul Smith <psmith@gnu.org>
1315 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1316 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1318 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1320 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1321 Fixes Savannah bug #25412.
1323 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1324 prototype for xmalloc.
1325 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1326 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1327 Loop over an array of extensions, instead of duplicating the same
1328 code inline. Use SearchPath followed by CreateFile, instead of
1329 the obsolete OpenFile. Fixes Savannah bug #17277.
1330 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1331 to `find_file'. Fixes Savannah bug #25662.
1333 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1335 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1336 Fixes Savannah bug #20495.
1338 2009-02-28 Ralf Wildenhues <address@hidden>
1340 * doc/make.texi (Instead of Execution): Document interaction of
1341 -t with phony targets.
1343 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1345 Introduce a new keyword "private" which applies to target-specific
1346 variables and prevents their values from being inherited.
1348 * variable.h (struct variable): Add private_var flag to each variable.
1349 Add a flag to specify which list entry switches to the parent target.
1350 * variable.c (define_variable_in_set): Initialize private_var flag.

1365 * function.c (func_foreach): Ditto.
1366 * read.c (eval, record_files): Ditto.
1367 * variable.c (define_variable_in_set): Ditto.
1369 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1371 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1374 * w32/subproc/build.bat (GCCBuild): Likewise.
1376 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1378 * job.c (construct_command_argv_internal): Avoid extra backslash
1379 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1382 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1384 * README.W32.template: Remove obsolete text about non-support for
1385 -jN without Unixy shell. Remove obsolete text about not supplying
1386 Visual Studio project files (we do supply them). Modify text to
1387 prefer GCC builds to MSC builds.
1389 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1391 * doc/make.texi (Empty Targets): Fix typo.
1393 2008-03-27 Paul Smith <psmith@gnu.org>

1406 `value' field is NULL.
1408 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1410 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1412 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1413 (TEXINFOS): Value changed to `doc/make.texi'.
1414 (.SUFFIXES): Use .texi instead of .texinfo.
1415 (make.info, make.dvi): Depend on doc/make.texi.
1416 (.texi.info): New target, instead of ".texinfo.info". Change -I
1417 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1418 (.texi): New target, instead of ".texinfo". Change -I switch to
1419 $(MAKEINFO) to look in doc/. Use --no-split.
1420 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1421 switch to $(MAKEINFO) to look in doc/.
1422 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1423 "*.i[0-9][0-9]" (due to --no-split above).

1425 (html, make_1.html): New targets.
1426 (.PHONY): Add "html".

1432 HAVE_DECL_SYS_SIGLIST.
1434 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1435 build does not use child_execute_job.
1437 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1438 export the SHELL environment variable to the child.
1440 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1442 * config.h.W32: Include sys/types.h.

1459 * remake.c (f_mtime): Print time difference values between 100 and
1460 ULONG_MAX in fixed-point notation rather than in exponention notation.
1462 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1464 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1465 a more complex value than a simple shell: if it's not a default
1466 shell now then expand it and see if is a default shell then.
1468 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1470 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1471 pathnames, with const strings.
1472 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1473 from the template (used for building from CVS, not a dist).
1475 2007-10-10 Paul Smith <psmith@gnu.org>
1477 * make.h: Add a prototype for w32_kill() (change suggested by
1478 Yongwei Wu <wuyongwei@gmail.com>).
1480 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1482 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1483 directories in Path.
1485 2007-09-12 Paul Smith <psmith@gnu.org>

1489 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1490 Provided by Diego Biurrun <diego@biurrun.de>
1492 2007-09-11 Paul Smith <psmith@gnu.org>
1494 * doc/make.texi (Special Variables): Moved this into the "How to
1495 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1496 (MAKEFILE_LIST) No longer a section; this was added into the
1497 "Special Variables" section.
1498 (Rule Introduction): Reference .RECIPEPREFIX.
1499 (Simple Makefile): Ditto.
1500 (Rule Syntax): Ditto.
1501 (Command Syntax): Ditto.
1502 (Error Messages): Ditto.
1504 2007-09-10 Paul Smith <psmith@gnu.org>
1506 * commands.c (print_commands): Don't print an extra line in the
1507 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1509 * read.c (construct_include_path): Add the full string to the cache; we
1510 were chopping the last char.
1512 * NEWS: Announce the .RECIPEPREFIX special variable.
1513 * variable.c (lookup_special_var): Rename from handle_special_var().
1514 (lookup_variable): Call the new name.
1515 (set_special_var): New function: handle setting of special variables.
1516 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1517 (do_variable_definition): Call it.
1518 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1519 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1520 * main.c (main): Create the .RECIPEPREFIX special variable.
1521 * read.c (eval): Remove the cmd_prefix characters from the command
1522 scripts here, so they're not stored in the commands array at all,
1523 rather than waiting and stripping them out during command construction.
1524 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1526 2007-08-15 Paul Smith <psmith@gnu.org>
1528 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1529 file has had the section info removed, so add some to make.texi
1530 before we include it.
1532 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1534 * remake.c (check_dep): Reset the target state for intermediate
1535 files. They might have been considered before but not updated
1536 then (order-only for example) but they will be this time.
1537 Fixes Savannah bug #'s 3330 and 15919.
1539 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1541 Fix Savannah bug #20549:
1542 * function.c (func_shell): Call construct_command_argv with zero
1544 * job.c (construct_command_argv_internal): New argument FLAGS; all
1546 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1548 * job.h (construct_command_argv_internal): Update prototype.
1550 2007-07-13 Paul Smith <psmith@gnu.org>
1552 * file.c (expand_deps): Use variable_buffer as the start of the
1553 buffer, not the original pointer (in case it was reallocated).
1554 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1555 Fixes Savannah bug #20452.
1557 2007-07-04 Paul Smith <psmith@gnu.org>
1559 * (ALL FILES): Update to GPLv3.

1564 2007-06-29 Thiemo Seufer <ths@mips.com>
1566 * maintMakefile: Update Translation Project location.
1568 2007-06-13 Paul Smith <psmith@gnu.org>

1571 "Expansion of a deferred"
1572 Fixes Savannah bug #20018.

1592 Dave Korn <dave.korn@artimi.com>
1594 2007-05-08 Paul Smith <psmith@gnu.org>
1596 Fix Savannah bug #19656:
1598 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1600 * make.h: Change all case-insensitive string compares to use
1601 strcasecmp() (from POSIX). If we don't have that but do have one
1602 of the others, define strcasecmp to be one of those instead. If
1603 we don't have any, declare a prototype for our own version.
1605 * misc.c (strcasecmp): Use this if we can't find any native
1606 case-insensitive string comparison function.
1607 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1608 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1610 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1611 strcasecmp() instead of stricmp().
1612 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1613 instead of strcmpi().
1614 * acinclude.m4: Remove the strcasecmp() check from here.
1616 2007-03-21 Paul Smith <psmith@gnu.org>
1618 * configure.in: Don't turn on case-insensitive file system support
1619 if --disable-... is given. Fixes Savannah bug #19348.
1621 2007-03-19 Paul Smith <psmith@gnu.org>
1623 * ALL: Use the strcache for all file name strings, or other
1624 strings which we will never free. The goal is to save memory by
1625 avoiding duplicate copies of strings. However, at the moment this
1626 doesn't save much memory in most situations: due to secondary
1627 expansion we actually save prerequisite lists twice (once before
1628 the secondary expansion, and then again after it's been parsed
1629 into individual file names in the dep list). We will resolve this
1630 in a future change, by doing the parsing up-front for targets
1631 where secondary expansion is not set.
1633 Moving things into the strcache also allows us to use const
1634 pointers in many more places.
1636 2007-01-03 Paul Smith <psmith@gnu.org>
1638 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1639 the function, not just the first. Fixes Savannah bug #18680.
1641 2006-11-18 Paul Smith <psmith@gnu.org>
1643 * strcache.c (strcache_add_len): Don't allocate a new buffer
1644 unless the string is not already nil-terminated. Technically this
1645 is a violation of the standard, since we may be passed an array
1646 that is not long enough to test one past. However, in make this
1647 is never true since we only use nil-terminated strings or
1648 sub-strings thereof.
1650 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1652 * main.c: New global cmd_prefix, defaults to '\t'.
1653 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1656 * dir.c: Constified.
1657 (dir_contents_file_exists_p): Check for an error return from
1658 readdir(), just in case.
1660 * commands.c: Constified.
1661 * default.c: Constified.
1662 * expand.c: Constified.
1663 * function.c: Partial constification.

1668 * w32/pathstuff.c: Partial constification.
1670 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1672 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1673 backslashes and drive letters as absolute.
1675 2006-10-22 Paul Smith <psmith@gnu.org>

1679 2006-10-21 Paul Smith <psmith@gnu.org>
1682 * arscan.c: Constified.
1684 2006-09-30 Paul Smith <psmith@gnu.org>
1686 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1687 point to lastword since the example was updated.
1688 Fixes Savannah bug #16304.
1689 (Secondary Expansion): Correct example description.
1690 Fixes Savannah bug #16468.
1691 (Makefile Contents): Clarify that comments cannot appear within
1692 variable references or function calls.
1693 Fixes Savannah bug #16577.
1694 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1695 Fixes Savannah bug #17701.
1696 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1698 prerequisites. Fixes Savannah bug #17880.
1699 (Rule Syntax): "lise" -> "list"
1700 (Multiple Rules): ... -> @dots{}
1701 (Splitting Lines): ditto.
1703 * remake.c (update_file_1): Prereqs that don't exist should be
1704 considered changed, for the purposes of $?.
1705 Fixes Savannah bug #16051.

1747 that don't have extended grep.
1748 (cvsclean): Use $(PERL) instead of perl.

1752 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1754 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1755 inner-scope variables don't mask outer-scope variables.

1816 Declare and define sh_chars_sh[].
1818 2006-03-23 Paul D. Smith <psmith@gnu.org>
1820 * configure.in: Look for build.sh.in in $srcdir so it will be
1821 built for remote configurations as well.
1823 * Makefile.am: Make sure to clean up build.sh during distclean.
1824 Fixes Savannah bug #16166.
1826 * misc.c (log_access): Takes a const char *.
1827 * function.c (fold_newlines): Takes an unsigned int *.
1828 Both fixes for Savannah bug #16170.
1830 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1832 * implicit.c (pattern_search): Call set_file_variables only
1833 if we have prerequisites that need second expansion. Fixes
1834 Savannah bug #16140.
1836 2006-03-19 Paul D. Smith <psmith@gnu.org>
1838 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1839 memory on hosts that don't support it directly.

1842 make sure I don't forget any).
1844 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1846 (die): Cleanup code was removed from here; call the new function.
1847 (main): If we are re-execing, clean up the jobserver first so we
1848 don't leak file descriptors.

1854 allow multiple concurrent runs.
1855 Patch from Joseph Myers <joseph@codesourcery.com>
1857 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1859 * dep.h (struct dep): Add the stem field.
1860 * misc.c (alloc_dep, free_dep): New functions.
1861 (copy_dep_chain): Copy stem.
1862 (free_dep_chain): Use free_dep.
1863 * read.c (record_files): Store stem in the dependency line.
1864 * file.c (expand_deps): Use stem stored in the dependency line. Use
1865 free_dep_chain instead of free_ns_chain.
1866 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1867 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.

1878 Fixes Savannah bug #15913.
1880 2006-03-09 Paul Smith <psmith@gnu.org>
1882 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1883 listed non-existent files as changed. Turns out there's a bug in
1884 the Linux kernel builds which means that this change causes
1885 everything to rebuild every time. We will re-introduce this fix
1886 in the next release, to give them time to fix their build system.
1887 Fixes Savannah bug #16002.
1888 Introduces Savannah bug #16051.
1890 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1905 2006-02-19 Paul D. Smith <psmith@gnu.org>
1907 * commands.c (set_file_variables): Realloc, not malloc, the static
1908 string values to avoid memory leaks.
1910 * expand.c (recursively_expand_for_file): Only set reading_file to
1911 an initialized value.
1913 * implicit.c (pattern_search): We need to make a copy of the stem
1914 if we get it from an intermediate dep, since those get freed.
1916 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1918 (enter_file) [VMS]: Ditto.

1923 * job.c (construct_command_argv_internal): Fix last change.
1925 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1926 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1927 the calls to _beginthreadex.
1929 * expand.c (recursively_expand_for_file): Initialize `save' to
1930 prevent compiler warnings.
1932 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1934 * job.c (construct_command_argv_internal): Don't create a temporary
1935 script/batch file if we are under -n. Call _setmode to switch the
1936 script file stream to text mode.

1940 * variable.c (merge_variable_set_lists): Don't try to merge the
1941 global_setlist. Not only is this useless, but it can lead to
1942 circularities in the linked list, if global_setlist->next in one
1943 list gets set to point to another list which also ends in
1945 Fixes Savannah bug #15757.
1947 2006-02-15 Paul D. Smith <psmith@gnu.org>
1949 Fix for Savannah bug #106.
1951 * expand.c (expanding_var): Keep track of which variable we're
1952 expanding. If no variable is being expanded, it's the same as
1954 * make.h (expanding_var): Declare it.
1955 * expand.c (recursively_expand_for_file): Set expanding_var to the
1956 current variable we're expanding, unless there's no file info in
1957 it (could happen if it comes from the command line or a default
1958 variable). Restore it before we exit.

1970 * read.c (eval): Even if the included filenames expands to the
1971 empty string we still need to free the allocated buffer.
1973 * implicit.c (pattern_search): If we allocated a variable set for
1974 an impossible file, free it.
1975 * variable.c (free_variable_set): New function.
1976 * variable.h: Declare it.
1978 * read.c (read_all_makefiles): Makefile names are kept in the
1979 strcache, so there's never any need to alloc/free them.
1982 * main.c (main): Add "archives" to the .FEATURES variable if
1983 archive support is enabled.
1984 * doc/make.texi (Special Variables): Document it.
1986 2006-02-13 Paul D. Smith <psmith@gnu.org>

1994 * (ALL FILES): Updated copyright and license notices.
1996 2006-02-10 Paul D. Smith <psmith@gnu.org>
1998 A new internal capability: the string cache is a read-only cache
1999 of strings, with a hash table interface for fast lookup. Nothing
2000 in the cache will ever be freed, so there's no need for reference
2001 counting, etc. This is the beginning of a full solution for
2002 Savannah bug #15182, but for now we only store makefile names here.
2004 * strcache.c: New file. Implement a read-only string cache.
2005 * make.h: Add prototypes for new functions.
2006 * main.c (initialize_global_hash_tables): Initialize the string cache.
2007 (print_data_base): Print string cache stats.
2008 * read.c (eval_makefile): Use the string cache to store makefile
2009 names. Rewrite the string allocation to be sure we free everything.

2013 * dir.c (dir_contents_file_exists_p): Don't opendir if the
2014 directory time stamp didn't change, except on FAT filesystems.

2039 -W, don't overwrite it with the real mtime.

2058 * filedef.h (struct file): Add a new LAST pointer.
2060 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
2061 the comparison. For 64-bits systems the result of the subtraction
2062 might not fit into an int. Use comparison instead.
2063 Fixes Savannah bug #15534.
2065 * doc/make.texi: Update the chapter on writing commands to reflect
2066 the changes made in 3.81 for backslash/newline and SHELL handling.
2068 2006-02-01 Paul D. Smith <psmith@gnu.org>
2070 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
2071 variable st is not used when it's not initialized.

2086 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2088 * remake.c (update_goal_chain): Set g->changed instead of
2089 incrementing it, as it is only 8-bit wide, and could overflow if

2094 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
2095 MAXIMUM_WAIT_OBJECTS.
2096 (process_wait_for_any_private): Change dimension of handles[]
2097 array to MAXIMUM_WAIT_OBJECTS.
2098 (process_used_slots): New function.
2099 (process_register): Don't register more processes than the
2100 available number of slots.
2101 (process_easy): Don't start new processes if all slots are used up.
2103 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
2104 are already more children than sub_proc.c can handle, behave as if
2105 the load were too high.
2106 (start_job_command): Fix a typo in error message when process_easy
2109 2006-01-14 Eli Zaretskii <eliz@gnu.org>
2111 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
2112 the shell is not sh.exe.
2114 * job.c (create_batch_file): Renamed from create_batch_filename;
2115 all callers changed. Don't close the temporary file; return its
2116 file descriptor instead. New arg FD allows to return the file
2118 (construct_command_argv_internal): Use _fdopen instead of fopen to
2119 open the batch file.
2121 2006-01-04 Paul D. Smith <psmith@gnu.org>
2123 * readme.vms: Updates for case-insensitive VMS file systems from
2124 Hartmut Becker <Hartmut.Becker@hp.com>.
2125 * dir.c (vms_hash): Ditto.
2126 * vmsify.c (copyto): Ditto.
2127 * vmsfunctions.c (readdir): Ditto.
2129 * make.1: Add a section on the exit codes for make.
2131 * doc/make.texi: A number of minor updates to the documentation.
2133 2006-01-03 Paul D. Smith <psmith@gnu.org>
2135 * remake.c (update_file_1): Mark a prerequisite changed if it
2138 * read.c (eval): Be sure to strip off trailing whitespace from the
2139 prerequisites list properly. Also, initialize all fields in
2140 struct dep when creating a new one.
2142 2005-12-28 Paul D. Smith <psmith@gnu.org>
2144 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2145 disable warnings for MSC.
2146 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2148 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2150 * doc/make.texi (Execution): Add a footnote about changes in
2151 handling of backslash-newline sequences. Mention the differences
2152 on MS-DOS and MS-Windows.
2154 * NEWS: More details about building the MinGW port and a pointer
2155 to README.W32. Fix the section name that describes the new
2156 backward-incompatible processing of backslash-newline sequences.
2157 The special processing of SHELL set to "cmd" is only relevant to
2158 MS-Windows, not MS-DOS.
2160 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2162 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2163 to DWORD, to avoid compiler warnings.
2164 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2165 use %ld in format, to avoid compiler warnings.
2167 * doc/make.texi (Special Targets): Fix a typo.
2168 (Appending): Fix cross-reference to Setting.
2169 (Special Variables, Secondary Expansion, File Name Functions)
2170 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2171 periods after a sentence.
2172 (Execution): Add @: after "e.g.".
2173 (Environment): Fix punctuation.
2174 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2175 (Shell Function, Target-specific): Add @: after "vs."
2177 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2179 * read.c (record_target_var): Initialize variable's export field
2180 with v_default instead of leaving it "initialized" by whatever
2181 garbage happened to be on the heap.
2183 2005-12-12 Paul D. Smith <psmith@gnu.org>
2185 * make.1: Fix some display errors and document all existing options.
2186 Patch by Mike Frysinger <vapier@gentoo.org>.
2188 2005-12-11 Paul D. Smith <psmith@gnu.org>
2190 * implicit.c (pattern_search): If 2nd expansion is not set for
2191 this implicit rule, replace the pattern with the stem directly,
2192 and don't re-expand the variable list. Along with the other
2193 .SECONDEXPANSION changes below, fixes bug #13781.
2195 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2197 * implicit.c (pattern_search): Mark other files that this rule
2198 builds as targets so that they are not treated as intermediates
2199 by the pattern rule search algorithm. Fixes bug #13022.
2201 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2203 * remake.c (notice_finished_file): Propagate the change of
2204 modification time to all the double-colon entries only if
2205 it is the last one to be updated. Fixes bug #14334.
2207 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2209 * function.c (func_flavor): Implement the flavor function which
2210 returns the flavor of a variable.
2211 * doc/make.texi (Functions for Transforming Text): Document it.
2212 * NEWS: Add it to the list of new functions.
2214 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2216 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2218 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2219 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2221 2005-10-26 Paul Smith <psmith@gnu.org>
2223 * read.c (record_files): Don't set deps flags if there are no deps.
2224 * maintMakefile: We only need to build the templates when we are
2225 creating a distribution, so don't do it for "all".
2227 2005-10-24 Paul D. Smith <psmith@gnu.org>
2229 Make secondary expansion optional: its enabled by declaring the
2230 special target .SECONDEXPANSION.
2232 * NEWS: Update information on second expansion capabilities.
2233 * doc/make.texi (Secondary Expansion): Document the
2234 .SECONDEXPANSION special target and its behavior.
2235 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2236 prerequisite list was found in a static pattern rule.
2237 (free_dep_chain): Declare a prototype.
2238 * file.c (parse_prereqs): New function: break out some complexity
2240 (expand_deps): If we aren't doing second expansion, replace % with
2241 the stem for static pattern rules. Call the new function.
2242 * filedef.h (parse_prereqs): Declare a prototype.
2243 * implicit.c (pattern_search): Initialize the new staticpattern
2245 * main.c (second_expansion): Declare a global variable to remember
2246 if the special target has been seen. Initialize the new
2247 staticpattern field for prerequisites.
2248 * make.h: Extern for second_expansion.
2249 * misc.c (free_dep_chain): New function: frees a struct dep list.
2250 * read.c (read_all_makefiles): Initialize the staticpattern field.
2251 (eval_makefile): Ditto.
2252 (record_files): Check for the .SECONDEXPANSION target and set
2253 second_expansion global if it's found.
2254 Use the new free_dep_chain() instead of doing it by hand.
2255 Set the staticpattern field for prereqs of static pattern targets.
2257 2005-10-16 Paul D. Smith <psmith@gnu.org>
2259 * main.c (main): Set CURDIR to be a file variable instead of a
2260 default, so that values of CURDIR inherited from the environment
2261 won't override the make value.
2263 2005-09-26 Paul D. Smith <psmith@gnu.org>
2265 * job.c (construct_command_argv_internal): If the line is empty
2266 remember to free the temporary argv strings.
2269 2005-09-16 Paul D. Smith <psmith@gnu.org>
2271 * job.c (start_job_command): The noerror flag is a boolean (single
2272 bit); set it appropriately.
2273 Reported by Mark Eichin <eichin@metacarta.com>
2275 2005-08-29 Paul D. Smith <psmith@gnu.org>
2277 * function.c (func_error): On Windows, output from $(info ...)
2278 seems to come in the wrong order. Try to force it with fflush().
2280 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2282 * read.c (record_files): Move code that sets stem for static
2283 pattern rules out of the if (!two_colon) condition so it is
2284 also executed for two-colon rules. Fixes Savannah bug #13881.
2286 2005-08-08 Paul D. Smith <psmith@gnu.org>
2288 * make.h: Don't test that __STDC__ is non-0. Some compilers
2289 (Windows for example) set it to 0 to denote "ISO C + extensions".
2292 2005-08-07 Paul D. Smith <psmith@gnu.org>
2294 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2295 conditional (slightly different version of a fix from Eli).
2297 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2298 If make is running in parallel without -k and two jobs die in a
2299 row, but not too close to each other, then make will quit without
2300 waiting for the rest of the jobs to die.
2302 * main.c (die): Don't reset err before calling reap_children() the
2303 second time: we still want it to be in the error condition.
2304 * job.c (reap_children): Use a static variable, rather than err,
2305 to control whether or not the error message should be printed.
2307 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2309 * w32/subproc/sub_proc.c: Include signal.h.
2310 (process_pipe_io, process_file_io): Pass a pointer to a local
2311 DWORD variable to GetExitCodeProcess. If the exit code is
2312 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2314 * job.c [WINDOWS32]: Include windows.h.
2315 (main_thread) [WINDOWS32]: New global variable.
2316 (reap_children) [WINDOWS32]: Get the handle for the main thread
2317 and store it in main_thread.
2319 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2320 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2321 doing anything else. When we are done, close the main thread
2322 handle and exit with status 130.
2324 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2326 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2329 * main.c (find_and_set_default_shell): If found a DOSish shell,
2330 set sh_found and the value of default_shell, and report the
2331 findings in debug mode.
2333 * job.c (construct_command_argv_internal): Check unixy_shell, not
2334 no_default_sh_exe, to decide whether to use Unixy or DOSish
2337 * README.W32: Update with info about the MinGW build.
2339 * build_w32.bat: Support MinGW.
2341 * w32/subproc/build.bat: Likewise.
2343 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2344 printing DWORD args.
2346 * function.c (windows32_openpipe): Fix format strings for printing
2349 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2351 (start_job_command): Fix format string for printing the result of
2353 (start_job_command) [WINDOWS32]: Do not define.
2354 (exec_command): Fix format string for printing HANDLE args.
2356 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2357 to avoid compiler warnings.
2358 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2359 (Note: some of these fixes were submitted independently by J. Grant)
2361 2005-07-30 J. Grant <jg@jguk.org>
2363 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2364 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2365 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2367 2005-07-15 Paul Smith <psmith@gnu.org>
2369 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2370 we don't have a POSIX shell, then revert to the old
2371 backslash-newline behavior (where they are stripped).
2374 2005-07-08 Paul D. Smith <psmith@gnu.org>
2376 * config.h.W32.template: Reorder to match the standard config.h,
2377 for easier comparisons.
2378 From J. Grant <jg@jguk.org>
2380 * maintMakefile: Remove .dep_segment before overwriting it, in
2381 case it's not writable or noclobber is set.
2382 * expand.c (variable_expand_string): Cast result of pointer
2383 arithmetic to avoid a warning.
2384 * main.c (switches): Add full-fledged final initializer.
2386 2005-07-06 Paul D. Smith <psmith@gnu.org>
2388 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2389 * signame.c (strsignal): If we found _sys_siglist[] or
2390 __sys_siglist[] use those instead of sys_siglist[].
2391 From Albert Chin <china@thewrittenword.com>
2393 2005-07-04 Paul D. Smith <psmith@gnu.org>
2395 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2396 globfree(); set up to use the GNU versions.
2397 From Martin Zinser <zinser@zinser.no-ip.info>
2399 2005-07-03 Paul D. Smith <psmith@gnu.org>
2401 From J. Grant <jg@jguk.org>:
2403 * README.W32.template: Update the Windows and tested MSVC versions.
2404 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2405 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2406 * build_w32.bat: Ditto.
2407 * w32/subproc/build.bat: Ditto.
2409 2005-06-28 Paul D. Smith <psmith@gnu.org>
2411 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2412 declaration was checked but not present.
2414 2005-06-27 Paul D. Smith <psmith@gnu.org>
2416 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2417 to unsigned long. Fixes Savannah bug #13550.
2419 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2420 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2421 Fixes Savannah bug #13551.
2423 2005-06-26 Paul D. Smith <psmith@gnu.org>
2425 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2426 it if ANSI_STRING is not set.
2428 2005-06-25 Paul D. Smith <psmith@gnu.org>
2430 * read.c (eval): If no filenames are passed to any of the
2431 "include" variants, don't print an error.
2432 * doc/make.texi (Include): Document this.
2433 Fixes Savannah bug #1761.
2435 * job.c (construct_command_argv_internal): Sanitize handling of
2436 backslash/newline pairs according to POSIX: that is, keep the
2437 backslash-newline in the command script, but remove a following
2438 TAB character, if present. In the fast path, make sure that the
2439 behavior matches what the shell would do both inside and outside
2440 of quotes. In the slow path, quote the backslash and put a
2441 literal newline in the string.
2442 Fixes Savannah bug #1332.
2443 * doc/make.texi (Execution): Document the new behavior and give
2445 * NEWS: Make a note of the new behavior.
2447 * make.h [WINDOWS32]: #include <direct.h>.
2448 Fixes Savannah bug #13478.
2450 * remake.c (name_mtime): If the stat() of a file fails and the -L
2451 option was given and the file is a symlink, take the best mtime of
2452 the symlink we can get as the mtime of the file and don't fail.
2453 Fixes Savannah bug #13280.
2455 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2456 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2457 inside a variable reference. Make this function static as it's
2459 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2460 parsing an unexpanded line looking for semicolons.
2461 Fixes Savannah bug #1454.
2462 * misc.c (remove_comments): Move this to read.c and make it static
2463 as it's only used there. Call find_char_unquote() with new arg.
2464 * make.h: Remove prototypes for find_char_unquote() and
2465 remove_comments() since they're static now.
2467 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2468 its export flag and obtain its value. When we need to re-exec,
2469 increment the value and add it into the environment.
2470 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2471 * NEWS: Mention MAKE_RESTARTS.
2472 * main.c (always_make_set): New variable. Change the -B option to
2473 set this one instead.
2474 (main): When checking makefiles, only set always_make_flag if
2475 always_make_set is set AND the restarts flag is 0. When building
2476 normal targets, set it IFF always_make_set is set.
2477 (main): Avoid infinite recursion with -W, too: only set what-if
2478 files to NEW before we check makefiles if we've never restarted
2479 before. If we have restarted, set what-if files to NEW _after_ we
2481 Fixes Savannah bug #7566:
2483 2005-06-17 Paul D. Smith <psmith@gnu.org>
2485 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2486 in the prerequisites list.
2488 2005-06-12 Paul D. Smith <psmith@gnu.org>
2490 Fix Savannah bug # 1328.
2492 * configure.in: Check for atexit().
2493 * misc.c (close_stdout): Test stdout to see if writes to it have
2494 failed. If so, be sure to exit with a non-0 error code. Based on
2495 code found in gnulib.
2496 * make.h: Prototype.
2497 * main.c (main): Install close_stdout() with atexit().
2499 2005-06-10 Paul D. Smith <psmith@gnu.org>
2501 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2503 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2504 headers; make vmsWaitForChildren() static; extern vmsify().
2505 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2506 Don't create child_execute_job() here (it's in vmsjobs.c).
2507 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2509 2005-06-09 Paul D. Smith <psmith@gnu.org>
2511 * variable.c (push_new_variable_scope): File variables point
2512 directly to the global_setlist variable. So, inserting a new
2513 scope in front of that has no effect on those variables: they
2514 don't go through current_variable_set_list. If we're pushing a
2515 scope and the current scope is global, push it "the other way" so
2516 that the new setlist is in the global_setlist variable, and
2517 next points to a new setlist with the global variable set.
2518 (pop_variable_scope): Properly undo a push with the new
2520 Fixes Savannah bug #11913.
2522 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2524 * job.c (reap_children): Don't die of the command failed but
2525 the dontcare flag is set. Fixes Savannah bug #13216.
2527 * implicit.c (pattern_search): When creating a target from
2528 an implicit rule match, lookup pattern target and set precious
2529 flag in a newly created target. Fixes Savannah bug #13218.
2531 2005-05-13 Paul D. Smith <psmith@gnu.org>
2533 Implement "if... else if... endif" syntax.
2535 * read.c (eval): Push all checks for conditional words ("ifeq",
2536 "else", etc.) down into the conditional_line() function.
2537 (conditional_line): Rework to allow "else if..." clause. New
2538 return value -2 for lines which are not conditionals. The
2539 ignoring flag can now also be 2, which means "already parsed a
2540 true branch". If that value is seen no other branch of this
2541 conditional can be considered true. In the else parsing if there
2542 is extra text after the else, invoke conditional_line()
2543 recursively to see if it's another conditional. If not, it's an
2544 error. If so, raise the conditional value to this level instead
2545 of creating a new conditional nesting level. Special check for
2546 "else" and "endif", which aren't allowed on the "else" line.
2547 * doc/make.texi (Conditional Syntax): Document the new syntax.
2549 2005-05-09 Paul D. Smith <psmith@gnu.org>
2551 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2552 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2553 recurses to the w32 directory, even on non-Windows systems. Use
2554 the method suggested in the automake manual.
2555 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2556 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2558 2005-05-07 Paul D. Smith <psmith@gnu.org>
2560 * main.c (die): If we're dying with a fatal error (not that a
2561 command has failed), write back any leftover tokens before we go.
2563 * job.c (set_child_handler_action_flags): If there are jobs
2564 waiting for the load to go down, set an alarm to go off in 1
2565 second. This allows us to wake up from a potentially long-lasting
2566 read() and start a new job if the load has gone down. Turn it off
2568 (job_noop): Dummy signal handler function.
2569 (new_job): Invoke it with the new semantics.
2571 * docs/make.texi: Document secondary expansion. Various cleanups
2574 2005-05-03 Paul D. Smith <psmith@gnu.org>
2576 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2577 the targets which are to ultimately be made are called "goals";
2578 see the GNU make manual. Also, MAKECMDGOALS, etc.
2580 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2581 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2582 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2584 2005-05-02 Paul D. Smith <psmith@gnu.org>
2586 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2587 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2588 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2589 functions to vmsjobs.c. #include it into jobs.c.
2591 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2592 jobserver tokens. I found that this happens when an exported
2593 recursive variable contains a $(shell ...) function reference: in
2594 this situation we could "forget" to write back a token.
2596 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2597 we have. It's not reliable to depend on the number of children in
2598 our linked list so keep a separate count.
2599 (new_job): Check jobserver_tokens rather than children &&
2600 waiting_jobs. Increment jobserver_tokens when we get one.
2601 (free_child): If jobserver_tokens is 0, internal error. If it's
2602 >1, write a token back to the jobserver pipe (we don't write a
2603 token for the "free" job). Decrement jobserver_tokens.
2605 * main.c: Add variable master_job_slots.
2606 (main): Set it to hold the number of jobs requested if we're the
2607 master process, when using the jobserver.
2608 (die): Sanity checks: first test jobserver_tokens to make sure
2609 this process isn't holding any tokens we didn't write back.
2610 Second, if master_job_slots is set count the tokens left in the
2611 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2613 2005-04-24 Paul D. Smith <psmith@gnu.org>
2615 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2616 with -l# can lose jobserver tokens, because waiting jobs are not
2617 consulted properly when checking for the "free" token.
2619 * job.c (free_child): Count waiting_jobs as having tokens.
2620 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2621 handle jobs waiting for the load to drop.
2623 2005-04-23 Paul D. Smith <psmith@gnu.org>
2625 * main.c (main): Be careful to not core if a variable setting in
2626 the environment doesn't contain an '='. This is illegal but can
2627 happen in broken setups.
2628 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2630 2005-04-12 Paul D. Smith <psmith@gnu.org>
2632 The second expansion feature causes significant slowdown. Timing
2633 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2634 read the makefile before the feature, to 11+s to do the same
2635 operations after the feature. Additionally, memory usage
2636 increased drastically. To fix this I added some intelligence that
2637 avoids the overhead of the second expansion unless it's required.
2639 * dep.h: Add a new boolean field, need_2nd_expansion.
2641 * read.c (eval): When creating the struct dep for the target,
2642 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2643 (record_files): If there's a "%" in a static pattern rule, it gets
2644 converted to "$*" so set need_2nd_expansion to 1.
2646 * file.c (expand_deps): Rework to be more efficient. Only perform
2647 initialize_file_variables(), set_file_variables(), and
2648 variable_expand_for_file() if the need_2nd_expansion is set.
2650 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2651 (pattern_search): Ditto.
2652 * main.c (handle_non_switch_argument): Ditto.
2654 * read.c (read_all_makefiles): Ditto.
2655 (eval_makefile): Ditto.
2657 2005-04-07 Paul D. Smith <psmith@gnu.org>
2659 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2660 * variable.c (sync_Path_environment): Ditto.
2661 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2663 * main.c (main): Define the .FEATURES variable.
2664 * NEWS: Announce .FEATURES.
2665 * doc/make.texi (Special Variables): Document .FEATURES.
2667 * remake.c (check_dep): If a file is .PHONY, update it even if
2668 it's marked intermediate. Fixes Savannah bug #12331.
2670 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2672 * file.c (expand_deps): Factor out the second expansion and
2673 prerequisite line parsing logic from snap_deps().
2675 * file.c (snap_deps): Use expand_deps(). Expand and parse
2676 prerequisites of the .SUFFIXES special target first. Fixes
2677 Savannah bug #12320.
2679 2005-03-13 Paul D. Smith <psmith@gnu.org>
2681 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2684 2005-03-11 Paul D. Smith <psmith@gnu.org>
2686 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2687 available, not undefined (from Earnie Boyd).
2689 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2691 * implicit.c (pattern_search): Mark an intermediate target as
2692 precious if it happened to be a prerequisite of some (other)
2693 target. Fixes Savannah bug #12267.
2695 2005-03-09 Paul D. Smith <psmith@gnu.org>
2697 * read.c (eval_makefile): Add alloca(0).
2698 (eval_buffer): Ditto.
2700 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2702 * main.c (main): Use o_file instead of o_default when defining
2703 the .DEFAULT_TARGET special variable.
2704 * read.c (eval): Use define_variable_global() instead of
2705 define_variable() when setting new value for the .DEFAULT_TARGET
2706 special variable. Fixes Savannah bug #12266.
2708 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2710 * imlicit.c (pattern_search): Mark files for which an implicit
2711 rule has been found as targets. Fixes Savannah bug #12202.
2713 2005-03-04 Paul D. Smith <psmith@gnu.org>
2716 * doc/make.texi (Automatic Variables): Document $|.
2718 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2720 * read.c (record_files): Instead of substituting % with
2721 actual stem value in dependency list replace it with $*.
2722 This fixes stem triple expansion bug.
2724 * implicit.c (pattern_search): Copy stem to a separate
2725 buffer and make it a properly terminated string. Assign
2726 this buffer instead of STEM (which is not terminated) to
2727 f->stem. Instead of substituting % with actual stem value
2728 in dependency list replace it with $*. This fixes stem
2729 triple expansion bug.
2731 2005-03-01 Paul D. Smith <psmith@gnu.org>
2733 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2734 on Windows, as it takes a handle not a pid. Just exit.
2735 Fix from patch #3679, provided by Alessandro Vesely.
2737 * configure.in: Update check for sys_siglist[] from autoconf manual.
2738 * signame.c (strsignal): Update to use the new autoconf macro.
2740 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2742 * read.c (record_files): Add a check for the list of prerequisites
2743 of a static pattern rule being empty. Fixes Savannah bug #12180.
2745 2005-02-28 Paul D. Smith <psmith@gnu.org>
2747 * doc/make.texi (Text Functions): Update docs to allow the end
2748 ordinal for $(wordlist ...) to be 0.
2749 * function.c (func_wordlist): Fail if the start ordinal for
2750 $(wordlist ...) is <1. Matches documentation.
2751 Resolves Savannah support request #103195.
2753 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2754 previously we were stopping when !-q, exactly the opposite. This
2755 has been wrong since version 1.34, in 1994!
2756 (update_file): If we got an error don't break out to run more
2757 double-colon rules: just return immediately.
2758 Fixes Savannah bug #7144.
2760 2005-02-27 Paul D. Smith <psmith@gnu.org>
2762 * misc.c (end_of_token): Make argument const.
2763 * make.h: Update prototype.
2765 * function.c (abspath, func_realpath, func_abspath): Use
2766 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2767 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2768 * read.c (record_files): Ditto.
2769 * variable.c (do_variable_definition): Ditto.
2771 * function.c (func_error): Create a new function $(info ...) that
2772 simply prints the message to stdout with no extras.
2773 (function_table_init): Add new function to the table.
2774 * NEWS: Add $(info ...) reference.
2775 * doc/make.texi (Make Control Functions): Document it.
2777 New feature: if the system supports symbolic links, and the user
2778 provides the -L/--check-symlink-time flag, then use the latest
2779 mtime between the symlink(s) and the target file.
2781 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2782 readlink(). If both are available, define MAKE_SYMLINKS.
2783 * main.c: New variable: check_symlink_flag.
2784 (usage): Add a line for -L/--check-symlink-times to the help string.
2785 (switches): Add -L/--check-symlink-times command line argument.
2786 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2787 print a warning and disable it again.
2788 * make.h: Declare check_symlink_flag.
2789 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2790 if the file is a symlink then check each link in the chain and
2791 choose the NEWEST mtime we find as the mtime for the file. The
2792 newest mtime might be the file itself!
2793 * NEWS: Add information about this new feature.
2794 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2796 Avoid core dumps described in Savannah bug # 12124:
2798 * file.c: New variable snapped_deps remember whether we've run
2800 (snap_deps): Set it.
2801 * filedef.h: Extern it.
2802 * read.c (record_files): Check snapped_deps; if it's set then
2803 we're trying to eval a new target/prerequisite relationship from
2804 within a command script, which we don't support. Fatal.
2806 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2808 Implementation of the .DEFAULT_TARGET special variable.
2810 * read.c (eval): If necessary, update default_target_name when
2812 * read.c (record_files): Update default_target_file if
2813 default_target_name has changed.
2814 * main.c (default_target_name): Define.
2815 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2816 default_target_name is set use default_target_file as a root
2818 * filedef.h (default_target_name): Declare.
2819 * dep.h (free_dep_chain):
2820 * misc.c (free_dep_chain): Change to operate on struct nameseq
2821 and change name to free_ns_chain.
2822 * file.c (snap_deps): Update to use free_ns_chain.
2824 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2826 Implementation of the second expansion in explicit rules,
2827 static pattern rules and implicit rules.
2829 * read.c (eval): Refrain from chopping up rule's dependencies.
2830 Store them in a struct dep as a single dependency line. Remove
2831 the code that implements SySV-style automatic variables.
2833 * read.c (record_files): Adjust the code that handles static
2834 pattern rules to expand all percents instead of only the first
2835 one. Reverse the order in which dependencies are stored so that
2836 when the second expansion reverses them again they appear in
2837 the makefile order (with some exceptions, see comments in
2838 the code). Remove the code that implements SySV-style automatic
2841 * file.c (snap_deps): Implement the second expansion and chopping
2842 of dependency lines for explicit rules.
2844 * implicit.c (struct idep): Define an auxiliary data type to hold
2845 implicit rule's dependencies after stem substitution and
2848 * implicit.c (free_idep_chain): Implement.
2850 * implicit.c (get_next_word): Implement helper function for
2851 parsing implicit rule's dependency lines into words taking
2852 into account variable expansion requests. Used in the stem
2855 * implicit.c (pattern_search): Implement the second expansion
2856 for implicit rules. Also fixes bug #12091.
2858 * commands.h (set_file_variables): Declare.
2859 * commands.c (set_file_variables): Remove static specifier.
2861 * dep.h (free_dep_chain): Declare.
2862 * misc.c (free_dep_chain): Implement.
2864 * variable.h (variable_expand_for_file): Declare.
2865 * expand.c (variable_expand_for_file): Remove static specifier.
2867 * make.h (strip_whitespace): Declare.
2868 * function.c (strip_whitespace): Remove static specifier.
2870 2005-02-26 Paul D. Smith <psmith@gnu.org>
2872 * main.c (main): Check for ferror() when reading makefiles from stdin.
2873 Apparently some shells in Windows don't close pipes properly and
2876 2005-02-24 Jonathan Grant <jg@jguk.org>
2878 * configure.in: Add MinGW configuration options, and extra w32 code
2880 * Makefile.am: Add MinGW configuration options, and extra w32 code
2882 * main.c: Determine correct program string (after last \ without .exe).
2883 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2885 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2886 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2887 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2888 environment support.
2890 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2892 * function.c (func_shell): When initializing error_prefix, check
2893 that reading file name is not null. This fixes long-standing
2894 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2896 2005-02-09 Paul D. Smith <psmith@gnu.org>
2898 * maintMakefile: Update the CVS download URL to simplify them.
2899 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2900 downloading the .texi files from Savannah now.
2902 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2904 * main.c (handle_non_switch_argument): Only add variables to
2905 command_variables if they're not already there: duplicate settings
2906 waste space and can be confusing to read.
2908 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2909 this header is never included by non-WINDOWS32 code, and it
2910 requires <config.h> to define which isn't always included first.
2912 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2913 testing MINGW32 versions.
2915 * main.c (log_working_directory): flush stdout to be sure the WD
2916 change is printed before any stderr messages show up.
2918 2005-02-01 Paul D. Smith <psmith@gnu.org>
2920 * maintMakefile (po_repo): Update the GNU translation site URL.
2922 2004-12-01 Paul D. Smith <psmith@gnu.org>
2924 * main.c (main): Change char* env_shell to struct variable shell_var.
2925 * variable.c (target_environment): Use new shell_var.
2927 2004-11-30 Paul D. Smith <psmith@gnu.org>
2929 * configure.in: The old way we avoided creating build.sh from
2930 build.sh.in before build.sh.in exists doesn't work anymore; we
2931 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2932 the help!). This also keeps automake from complaining.
2933 * Makefile.am (README): Add a dummy target so automake won't
2934 complain that this file doesn't exist when we checkout from CVS.
2935 * maintMakefile (.dep_segment): Rewrite this rule since newer
2936 versions of automake don't provide DEP_FILES.
2938 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2940 Implementation of `realpath' and `abspath' built-in functions.
2942 * configure.in: Check for realpath.
2943 * function.c (abspath): Return an absolute file name that does
2944 not contain any `.' or `..' components, nor repeated `/'.
2945 * function.c (func_abspath): For each name call abspath.
2946 * function.c (func_realpath): For each name call realpath
2947 from libc or delegate to abspath if realpath is not available.
2948 * doc/make.texi (Functions for File Names): Document new functions.
2949 * doc/make.texi (Quick Reference): Ditto.
2951 2004-11-28 Paul D. Smith <psmith@gnu.org>
2953 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2954 arguments. Fixes bug #10252.
2956 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2958 * main.c (main): Set SHELL to v_noexport by default. Remember the
2959 original environment setting of SHELL in the env_shell variable.
2960 * main.h: Export new env_shell variable.
2961 * variable.c (target_environment): If we find a v_noexport
2962 variable for SHELL, add a SHELL variable with the env_shell value.
2963 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2964 * doc/make.texi (Variables/Recursion): Ditto.
2966 2004-11-28 Paul D. Smith <psmith@gnu.org>
2968 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2969 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2970 Patch by Alessandro Vesely.
2972 2004-11-12 Paul D. Smith <psmith@gnu.org>
2974 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2975 the command line if it's inside a string.
2976 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2978 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2980 * function.c (func_lastword): New function: return last word
2981 from the list of words.
2982 * doc/make.texi: Document $(lastword ). Fix broken links in
2983 Quick Reference section.
2985 2004-10-06 Paul D. Smith <psmith@gnu.org>
2987 Apply patch from Alessandro Vesely, provided with bug # 9748.
2988 Fix use of tmpnam() to work with Borland C.
2990 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2991 construction of a temporary filename, and call new function
2992 create_batch_filename().
2993 (create_batch_filename) [WINDOWS32]: New function to create a
2996 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2998 * read.c (record_target_var): Expand simple pattern-specific
3000 * variable.c (initialize_file_variables): Do not expand simple
3001 pattern-specific variable.
3003 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
3005 * remake.c (update_file_1): When rebuilding makefiles inherit
3006 dontcare flag from a target that triggered update.
3008 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
3010 * variable.c (initialize_file_variables): Mark pattern-specific
3011 variable as a per-target and copy export status.
3013 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
3015 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
3017 * implicit.c (pattern_search): When considering an implicit rule's
3018 prerequisite check that it is actually a target rather then
3019 just an entry in the file hashtable.
3021 2004-09-21 Paul D. Smith <psmith@gnu.org>
3023 * read.c (readstring): Fix some logic errors in backslash handling.
3024 (eval): Remove some unnecessary processing in buffer handling.
3025 (record_target_var): Assert that parse_variable_definition() succeeded.
3026 Reported by: Markus Mauhart <qwe123@chello.at>.
3028 * misc.c: Removed the sindex() function. All instances of this
3029 function were trivially replaceable by the standard strstr()
3030 function, and that function will always have better (or certainly
3031 no worse) performance than the very simple-minded algorithm
3032 sindex() used. This can matter with complex makefiles.
3033 * make.h: Remove the prototype for sindex().
3034 * function.c (subst_expand): Convert sindex() call to strstr().
3035 This means we no longer need to track the TLEN value so remove that.
3036 (func_findstring): Convert sindex() to strstr().
3037 * commands.c (chop_commands): Convert sindex() calls to strstr().
3038 Suggested by: Markus Mauhart <qwe123@chello.at>.
3040 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
3041 idea behind Savannah Patch #3144 from david.baird@homemail.com.
3042 If SHELL is set to CMD.EXE then assume it's batch-mode and
3043 non-unixy. I wrote the code differently from the patch, though,
3044 to make it safer. This also resolves bug #9174.
3046 2004-09-20 Paul D. Smith <psmith@gnu.org>
3048 * expand.c (variable_expand_string): Modify to invoke
3049 patsubst_expand() instead of subst_expand(); the latter didn't
3050 handle suffix patterns correctly.
3051 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
3052 was used only from variable_expand_string() and is no longer used
3054 (func_subst): Ditto, on call to subst_expand().
3055 (patsubst_expand): Require the percent pointers to point to the
3056 character after the %, not to the % itself.
3057 * read.c (record_files): New call criteria for patsubst_expand().
3058 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
3059 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
3061 2004-09-19 Paul D. Smith <psmith@gnu.org>
3063 * function.c (subst_expand): Fix a check in by_word: look for a
3064 previous blank if we're beyond the beginning of the string, not
3065 the beginning of the word.
3066 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3068 2004-05-16 Paul D. Smith <psmith@gnu.org>
3070 * remake.c (update_goal_chain): Change the argument specifying
3071 whether we're rebuilding makefiles to be a global variable,
3072 REBUILDING_MAKEFILES.
3073 (complain): Extract the code that complains about no rules to make
3074 a target into a separate function.
3075 (update_file_1): If we tried to rebuild a file during the makefile
3076 rebuild phase and it was dontcare, then no message was printed.
3077 If we then try to build the same file during the normal build,
3078 print a message this time.
3079 (remake_file): Don't complain about un-remake-able files when
3080 we're rebuilding makefiles.
3082 2004-05-11 Paul D. Smith <psmith@gnu.org>
3084 * job.c (construct_command_argv_internal): OS/2 patches from
3085 Andreas Buening <andreas.buening@nexgo.de>.
3087 2004-05-10 Paul D. Smith <psmith@gnu.org>
3089 * remake.c (update_file): Don't walk the double-colon chain unless
3090 this is a double-colon rule. Fix suggested by Boris Kolpackov
3091 <boris@kolpackov.net>.
3093 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3094 * readme.vms: New section describing OpenVMS support and issues.
3095 * default.c (default_variables): Add support for IA64.
3096 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3097 without some privilege aborts make with the error
3098 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3099 pressing Ctrl+Y and the input device is no terminal. The change
3100 catches this error and just continues.

3106 * commands.c (set_file_variables): Set $< properly in the face of
3107 order-only prerequisites.
3108 Patch from Boris Kolpackov <boris@kolpackov.net>
3110 2004-04-21 Bob Byrnes <byrnes@curl.com>
3112 * main.c (main): Notice failures to remake makefiles.
3114 2004-03-28 Paul D. Smith <psmith@gnu.org>
3116 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3118 * job.c: No default shell for RISC OS.
3119 (load_too_high): Hard-code the return to 1.
3120 (construct_command_argv_internal): No sh_chars or sh_cmds.
3121 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3123 2004-03-20 Paul D. Smith <psmith@gnu.org>
3125 * variable.c (do_variable_definition): Don't append from the
3126 global set if a previous non-appending target-specific variable
3127 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3130 * expand.c (reference_variable): Don't give up on variables with
3131 no value that have the target-specific append flag set: they might
3132 have a value after all. Reported by Oliver Schmidt
3133 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3134 <nikulin@dx1cmd.inp.nsk.su>.
3136 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3137 refer to absolute pathnames in directories that don't exist: some
3138 portion of the makefile could create those directories before we
3139 match the pattern. Fixes bugs #775 and #108.
3141 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3143 * main.c (main): Free makefile_mtimes if we have any.
3144 * README.W32.template: Update documentation for the current status
3145 of the MS-Windows port.
3146 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3147 environment variable is sometimes already defined which causes the
3149 * main.c (debug_signal_handler): Only define this function if
3150 SIGUSR1 is available.
3152 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3154 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3155 * README.OS2.template: Documentation updates.
3156 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3157 link line for safety.
3158 * maintMakefile (build.sh.in): Remove an extraneous ")".
3159 * job.c (child_execute_job): Close saved FDs.
3160 * job.c (exec_command) [OS/2]: exec_command(): If the command
3161 can't be exec'ed and if the shell is not Unix-sh, then try again
3162 with argv = { "cmd", "/c", ... }. Normally, this code is never
3163 reached for the cmd shell unless the command really doesn't exist.
3164 (construct_command_argv_internal) [OS/2]: The code for cmd
3165 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3166 The CMD builtin commands are case insensitive so use strcasecmp().
3168 2004-03-19 Paul D. Smith <psmith@gnu.org>
3170 * read.c (do_define): Re-order line counter increment so the count
3171 is accurate (we were losing one line per define). Reported by
3172 Dave Yost <Dave@Yost.com>.
3174 2004-03-06 Paul D. Smith <psmith@gnu.org>
3176 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3178 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3179 * misc.c (message,error,fatal): Ditto.
3180 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3181 * config.h.W32.template: Ditto.
3182 * config.h-vms.template: Ditto.
3183 * config.ami.template: Ditto.
3185 2004-03-04 Paul D. Smith <psmith@gnu.org>
3187 * README.template: Add a note about broken /bin/sh on SunOS
3188 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3190 * misc.c (message, error, fatal): Don't use "..." if we're using
3191 varargs. ansi2knr should handle this but it doesn't work: it
3192 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3193 done. On many systems (SunOS for example) va_dcl is a #define.
3194 So, force the use of the non-"..." version on pre-ANSI compilers.
3196 * maintMakefile (sign-dist): Create some rules to help automate
3197 the new GNU ftp upload method.
3199 2004-02-24 Paul D. Smith <psmith@gnu.org>
3201 * config.h.W32.template: Add HAVE_STDARG_H
3202 * config.h-vms.template: Ditto.
3203 * config.ami.template: Ditto.
3205 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3207 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3208 * build_w32.bat: Remove extra "+".
3210 2004-02-23 Paul D. Smith <psmith@gnu.org>
3212 * make.h: Create an UNUSED macro to mark unused parameters.
3213 * (many): Clean up warnings by applying UNUSED, fixing
3214 signed/unsigned incompatibilities, etc.
3216 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3218 * filedef.h: Name the command_state enumeration.
3219 * file.c (set_command_state): Use the enumeration in the function
3222 * configure.in: Explicitly set SET_MAKE to empty, to disable
3223 MAKE=make even when no make already exists. Fix bug #3823.
3225 2004-02-22 Paul D. Smith <psmith@gnu.org>
3227 * maintMakefile: Perl script to clean up all non-CVS files. Use
3228 it on all the subdirectories for the cvs-clean target.
3230 * main.c (decode_switches): Require non-empty strings for all our
3231 string command-line options. Fixes Debian bug # 164165.
3233 * configure.in: Check for stdarg.h and varargs.h.
3234 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3235 for printing messages.
3236 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3241 A number of patches for OS/2 support from Andreas Buening
3242 <andreas.buening@nexgo.de>:
3244 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3245 disable the SIGCHLD handler.
3246 (reap_children) [OS/2]: Remove special handling of job_rfd.
3247 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3248 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3249 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3250 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3251 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3254 2004-02-21 Paul D. Smith <psmith@gnu.org>
3256 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3257 <mail@kristov.de> reports that if process_begin() fails we don't
3258 handle the error condition correctly in all cases.
3259 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3260 to have a newline on the message.
3262 * job.c (construct_command_argv_internal): Add "test" to UNIX
3263 sh_cmds[]. Fixes Savannah bug # 7606.
3265 2004-02-04 Paul D. Smith <psmith@gnu.org>
3267 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3268 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3269 Hartmut Becker <Hartmut.Becker@hp.com>.
3271 2004-01-21 Paul D. Smith <psmith@gnu.org>
3273 * job.c (load_too_high): Implement an algorithm to control the
3274 "thundering herd" problem when using -l to control job creation
3275 via the load average. The system only recomputes the load once a
3276 second but we can start many jobs in a second. To solve this we
3277 keep track of the number of jobs started in the last second and
3278 apply a weight to try to guess what a correct load would be.
3279 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3280 Also fixes bug #4693.
3281 (reap_children): Decrease the job count for this second.
3282 (start_job_command): Increase the job count for this second.
3284 * read.c (conditional_line): Expand the text after ifn?def before
3285 checking to see if it's a single word. Fixes bug #7257.
3287 2004-01-09 Paul D. Smith <psmith@gnu.org>
3289 * file.c (print_file): Recurse to print all targets in
3290 double-colon rules. Fixes bug #4518, reported (with patch) by
3291 Andrew Chatham <chatham@google.com>.
3293 2004-01-07 Paul D. Smith <psmith@gnu.org>
3295 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3296 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3297 AC_FUNC_SETVBUF_REVERSED.
3299 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3300 (MAKE Variable): Fix Savannah bug #4898.
3302 * job.c (construct_command_argv_internal): Add "!" to the list of
3303 shell escape chars. POSIX sh allows it to appear before a
3304 command, to negate the exit code. Fixes bug #6404.
3306 * implicit.c (pattern_search): When matching an implicit rule,
3307 remember which dependencies have the ignore_mtime flag set.
3308 Original fix provided in Savannah patch #2349, by Benoit
3309 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3311 2003-11-22 Paul D. Smith <psmith@gnu.org>
3313 * README.W32.template (Outputs): Clarification on -j with
3314 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3317 2003-11-02 Paul D. Smith <psmith@gnu.org>
3319 * function.c (func_if): Strip all the trailing whitespace from the
3320 condition, then don't expand it. Fixed bug # 5798.
3322 * expand.c (recursively_expand_for_file): If we're expanding a
3323 variable with no file context, then use the variable's context.
3326 2003-10-21 Paul D. Smith <psmith@gnu.org>
3328 * main.c (log_working_directory): Add newlines to printf()s.
3330 * README.cvs: Add a note to ignore warnings during autoreconf.
3332 * maintMakefile (po_repo): Set a new URL for PO file updates.
3333 (get-config/config.guess get-config/config.sub): Get these files
3334 from the Savannah config project instead of ftp.gnu.org.
3336 2003-10-05 Paul Eggert <eggert@twinsun.com>
3338 * main.c (main): Avoid potential subscript error if environ has
3341 2003-08-22 Paul D. Smith <psmith@gnu.org>
3343 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3344 systems which don't yet implement the C89 standard :-/.
3346 2003-07-18 Paul D. Smith <psmith@gnu.org>
3348 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3349 [WINDOWS32]: Initialize hash.
3351 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3353 * dir.c (read_dirstream): Provide a workaround for broken versions of
3354 the MinGW dirent structure.
3356 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3358 * w32/include/dirent.h: Add __MINGW32__ filter.
3360 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3362 * make.h: Add global declaration of *make_host.
3363 * main.c (print_usage): Remove local declaration of *make_host.
3364 (print_version): Display "This program built for ..." after Copyright
3367 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3369 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3370 execution of "makeinfo --html make.texi".
3372 2003-04-30 Paul D. Smith <psmith@gnu.org>
3374 * build.template: Make some changes to maybe allow this script to
3375 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3377 * README.OS2.template: New file for OS/2 support. Original
3378 contributed by Andreas Buening.
3379 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3382 2003-04-19 Paul D. Smith <psmith@gnu.org>
3384 Fix bug #1405: allow a target to match multiple pattern-specific
3387 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3388 variable.c, where they've always belonged.
3389 * rule.h: Move the prototypes and struct pattern_var as well.
3390 * variable.c (initialize_file_variables): Invoke
3391 lookup_pattern_var() in a loop, until no more matches are found.
3392 If a match is found, create a new variable set for the target's
3393 pattern variables. Then merge the contents of each matching
3394 pattern variable set into the target's pattern variable set.
3395 (lookup_pattern_var): Change this function to be usable
3396 in a loop. It takes a starting position: if NULL, start at the
3397 beginning; if non-NULL, start with the pattern variable after that
3398 position, and return the next matching pattern.
3399 (create_pattern_var): Create a unique instance of
3400 pattern-specific variables for every definition in the makefile.
3401 Don't combine the same pattern together. This allows us to
3402 process the variable handling properly even when the same pattern
3403 is used multiple times.
3404 (parse_variable_definition): New function: break out the parsing
3405 of a variable definition line from try_variable_definition.
3406 (try_variable_definition): Call parse_variable_definition to
3408 (print_variable_data_base): Print out pattern-specific variables.
3409 * variable.h (struct variable): Remember when a variable is
3410 conditional. Also remember its flavor.
3411 (struct pattern_var): Instead of keeping a variable set, we just
3412 keep a single variable for each pattern.
3413 * read.c (record_target_var): Each pattern variable contains only a
3414 single variable, not a set, so create it properly.
3415 * doc/make.texi (Pattern-specific): Document the new behavior.
3417 2003-04-17 Paul D. Smith <psmith@gnu.org>
3419 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3420 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3421 file/directory naming rules for VMS so I can't tell whether this
3424 2003-04-09 Paul D. Smith <psmith@gnu.org>
3426 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3427 DOS-style pathnames: backslash separators and drive specifiers.
3429 2003-03-28 Paul D. Smith <psmith@gnu.org>
3431 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3432 the intermediate flag on all targets. Fixes bug #2515.
3434 2003-03-24 Paul D. Smith <psmith@gnu.org>
3436 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3437 Upgrade to autoconf 2.57 and automake 1.7.3.
3439 * job.c: More OS/2 changes from Andreas Buening.
3441 * file.c (print_file): Fix variable initialization.
3444 * remake.c (notice_finished_file):
3446 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3447 some calls (like readdir()) return NULL in valid situations
3448 without resetting errno. Fixes bug #2846.
3450 2003-02-25 Paul D. Smith <psmith@gnu.org>
3452 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3454 * job.c (_is_unixy_shell) [OS/2]: New function.
3455 Set default shell to /bin/sh.
3456 (reap_children): Close the job_rfd pipe here since we don't use a
3458 (set_child_handler_action_flags): define this to empty on OS/2.
3459 (start_job_command): Close the jobserver pipe and use
3460 child_execute_job() instead of fork/exec.
3461 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3462 rather than exec'ing, then reconfigure stdin/stdout.
3463 (exec_command): Rewrite to use spawn instead of exec. Return the
3466 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3467 in DOS. Handle the TEMP environment variable as in DOS. Don't
3468 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3469 use -j in DOS mode. Use child_execute_job() instead of
3472 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3475 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3476 prototypes that return values.
3478 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3480 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3481 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3483 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3486 2003-02-24 Paul D. Smith <psmith@gnu.org>
3488 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3489 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3490 (child_execute_job) [VMS]: Handle error status properly.
3491 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3493 * function.c (func_shell): Use EINTRLOOP() while reading from the
3494 subshell pipe (Fixes bug #2502).
3495 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3497 * main.c (main): Ditto.
3499 2003-01-30 Paul D. Smith <psmith@gnu.org>
3501 * read.c (eval): eval() was not fully reentrant, because the
3502 collapsed buffer was static. Change it to be an automatic
3503 variable so that eval() can be invoked recursively.
3505 (eval): Apply patch # 1022: fix memory reference error on long
3506 target-specific variable lines.
3507 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3509 * function.c (check_numeric): Combine the is_numeric() function
3510 into this function, since it's only called from one place.
3511 Constify this function. Have it print the incorrect string in the
3512 error message. Fixes bug #2407.
3513 (strip_whitespace): Constify.
3514 (func_if): Constify.
3515 * expand.c (expand_argument): Constify.
3517 2003-01-29 Paul D. Smith <psmith@gnu.org>
3519 Fix bug # 2169, also reported by other people on various systems.
3521 * make.h: Some systems, such as Solaris and PTX, do not fully
3522 implement POSIX-compliant SA_RESTART functionality; important
3523 system calls like stat() and readdir() can still fail with EINTR
3524 even if SA_RESTART has been set on the signal handler. So,
3525 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3526 EINTR for system calls which return -1 or 0 (NULL), respectively,
3528 Also, remove the old atomic_stat()/atomic_readdir() and
3529 HAVE_BROKEN_RESTART handling.
3531 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3533 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3534 * remake.c (touch_file): Ditto.
3536 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3537 * read.c (construct_include_path): Ditto.
3538 * remake.c (name_mtime): Ditto.
3539 * vpath.c (selective_vpath_search): Ditto.
3540 * dir.c (find_directory): Ditto.
3541 (local_stat): Ditto.
3542 (find_directory): Use ENULLLOOP() to wrap opendir().
3543 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3545 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3546 atomic_readdir() handling.
3548 2003-01-22 Paul D. Smith <psmith@gnu.org>
3550 * function.c (func_call): Fix Bug #1744. If we're inside a
3551 recursive invocation of $(call ...), mask any of the outer
3552 invocation's arguments that aren't used by this one, so that this
3553 invocation doesn't "inherit" them accidentally.
3555 2002-12-05 Paul D. Smith <psmith@gnu.org>
3557 * function.c (subst_expand): Valery Khamenia reported a
3558 pathological performance hit when doing substitutions on very
3559 large values with lots of words: turns out we were invoking
3560 strlen() a ridiculous number of times. Instead of having each
3561 call to sindex() call strlen() again, keep track of how much of
3562 the text we've seen and pass the length to sindex().
3564 2002-11-19 Paul D. Smith <psmith@gnu.org>
3566 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3569 2002-11-16 Paul D. Smith <psmith@gnu.org>
3571 * NMakefile.template (OBJS): Add hash.c object file.
3572 * SMakefile.template (srcs): Ditto.
3573 * Makefile.ami (objs): Ditto.
3574 * build_w32.bat: Ditto.
3576 * Makefile.DOS.template: Remove extra dependencies.
3578 2002-10-25 Paul D. Smith <psmith@gnu.org>
3580 * expand.c (install_variable_buffer): New function. Install a new
3581 variable_buffer context and return the previous one.
3582 (restore_variable_buffer): New function. Free the current
3583 variable_buffer context and put a previously saved one back.
3584 * variable.h: Prototypes for {install,restore}_variable_buffer.
3585 * function.c (func_eval): Push a new variable_buffer context
3586 before we eval, then restore the old one when we're done.
3589 * read.c (install_conditionals): New function. Install a new
3590 conditional context and return the previous one.
3591 (restore_conditionals): New function. Free the current
3592 conditional context and put a previously saved one back.
3593 (eval): Use the {install,restore}_conditionals for "include"
3595 (eval_buffer): Use {install,restore}_conditionals to preserve the
3596 present conditional state before we evaluate the buffer.
3599 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3601 (Recursion): Add a variable index entry for CURDIR.
3603 * README.cvs: Update to appropriate versions.
3604 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3605 don't need to copy loadavg.c: automake is smart enough to create
3606 it for me. Still have a bug in automake related to ansi2knr tho.
3608 2002-10-14 Paul D. Smith <psmith@gnu.org>
3610 * remake.c (notice_finished_file): Only touch targets if they have
3611 at least one command (as per POSIX). Resolve Bug #1418.
3613 * *.c: Convert to using ANSI C-style function definitions.
3614 * Makefile.am: Enable the ansi2knr feature of automake.
3615 * configure.in: ditto.
3617 2002-10-13 Paul D. Smith <psmith@gnu.org>
3619 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3620 for automatic variable values like $^, etc. In the case of very
3621 large lists of prerequisites this causes problems. Instead reuse
3622 a static buffer (resizeable) for each variable.
3624 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3625 target-specific variable definitions. Check for it and set an
3627 (record_target_var): Set the export field to v_export if the
3628 "exported" flag is set.
3629 * doc/make.texi (Target-specific): Document the ability to use
3632 * doc/make.texi: Change the name of the section on automatic
3633 variables from "Automatic" to "Automatic Variables". Added text
3634 clarifying the scope of automatic variables.
3636 2002-10-04 Paul D. Smith <psmith@gnu.org>
3638 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3640 (record_files): Ditto.
3642 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3643 the search for the '=' to only within the enclosing parens.
3645 2002-10-03 Paul D. Smith <psmith@gnu.org>
3647 Version 3.80 released.
3649 * dir.c: Change hash functions to use K&R function definition style.
3650 * function.c: Ditto.
3652 * variable.c: Ditto.
3654 Update to automake 1.7.
3656 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3657 (pdf): Remove this target as automake now provides one.
3659 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3661 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3663 * makefile.com: Updates for GNU make 3.80.
3664 * makefile.vms: Ditto.
3666 2002-09-23 Paul D. Smith <psmith@gnu.org>
3668 * read.c (enum make_word_type): Remove w_comment.
3669 (get_next_mword): Don't treat comment characters as special; where
3670 this function is used we will never see a comment (it's stripped
3671 before we get here) and treating comments specially means that
3672 targets like "foo\#bar" aren't handled properly.
3674 2002-09-18 Paul D. Smith <psmith@gnu.org>
3676 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3678 * read.c (eval): Expansion of arguments to export/unexport was
3679 ignoring all arguments after the first one. Change the algorithm
3680 to expand the whole line once, then parse the results.
3682 2002-09-17 Paul D. Smith <psmith@gnu.org>
3684 Fix Bug #940 (plus another bug I found while looking at this):
3686 * read.c (record_target_var): enter_file() will add a new entry if
3687 it's a double-colon target: we don't want to do that in this
3688 situation. Invoke lookup_file() and only enter_file() if it does
3689 not already exist. If the file we get back is a double-colon then
3690 add this variable to the "root" double-colon target.
3692 * variable.c (initialize_file_variables): If this file is a
3693 double-colon target but is not the "root" target, then initialize
3694 the root and make the root's variable list the parent of our
3697 2002-09-13 Paul D. Smith <psmith@gnu.org>
3699 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3701 * hash.c (round_up_2): Get rid of a warning.
3703 2002-09-12 Paul D. Smith <psmith@gnu.org>
3705 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3706 so it doesn't complain about getloadavg.c.
3708 * commands.c (set_file_variables): Make sure we always alloca() at
3709 least 1 character for the value of $? (for '\0').
3711 2002-09-11 Paul D. Smith <psmith@gnu.org>
3713 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3714 macro to use RESULT instead of the incorrect _RESULT_.
3716 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3717 and atomic_readdir(). We need to #include dirent.h to get this to
3719 * misc.c (atomic_readdir): Fix typos.
3721 2002-09-10 Paul D. Smith <psmith@gnu.org>
3723 * read.c (eval): Expand variable lists given to export and
3724 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3725 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3727 * doc/make.texi (Variables/Recursion): Document this.
3728 (Conditional Syntax): And here.
3730 2002-09-09 Paul D. Smith <psmith@gnu.org>
3732 * configure.in: Check for memmove().
3734 2002-09-07 Paul D. Smith <psmith@gnu.org>
3736 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3737 Michael Sterrett <msterret@coat.com> reports that while it has
3738 SA_RESTART, it does not work properly.
3740 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3741 that invokes stat() and loops to do it again if it returns EINTR.
3742 (atomic_readdir): Ditto, with readdir().
3744 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3745 and readdir() to atomic_stat() and atomic_readdir().
3747 2002-09-04 Paul D. Smith <psmith@gnu.org>
3749 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3750 reports that GNU make sometimes doesn't recognize that targets can
3751 be made, when directories can be created as prerequisites. He
3752 reports that changing the order of predicates in the DEP->changed
3753 flag test so that lookup_file() is always performed, solves this
3756 2002-08-08 Paul D. Smith <psmith@gnu.org>
3758 * configure.in: Require a newer version of gettext.
3760 * misc.c (perror_with_name): Translate the format string (for
3761 right-to-left language support).
3762 (pfatal_with_name): Ditto.
3764 * main.c: Create a static array of strings to store the usage
3765 text. This is done to facilitate translations.
3766 (struct command_switch): Remove argdesc and description fields.
3767 (switches): Remove values for obsolete fields.
3768 (print_usage): Print each element of the usage array.
3770 * hash.c: Change function definitions to be K&R style.
3772 2002-08-02 Paul D. Smith <psmith@gnu.org>
3774 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3775 this one because it's too hard to get right. We'll look at it for
3777 * main.c (main): Don't create the .TARGETS variable.
3778 * variable.c (handle_special_var): Don't handle .TARGETS.
3780 2002-08-01 Paul D. Smith <psmith@gnu.org>
3782 * main.c (switches): Add a new option, -B (--always-make). If
3783 specified, make will rebuild all targets that it encounters even
3784 if they don't appear to be out of date.
3785 (always_make_flag): New flag.
3786 * make.h: Extern always_make_flag.
3787 * remake.c (update_file_1): Check always_make_flag; if it's set we
3788 will always rebuild any target we can, even if none of its
3789 prerequisites are newer.
3792 * doc/make.texi (Shell Function): Make it clear that make
3793 variables marked as "export" are not passed to instances of the
3796 Add new introspection variable .VARIABLES and .TARGETS.
3798 * variable.c (handle_special_var): New function. If the variable
3799 reference passed in is "special" (.VARIABLES or .TARGETS),
3800 calculate the new value if necessary. .VARIABLES is handled here:
3801 walk through the hash of defined variables and construct a value
3802 which is a list of the names. .TARGETS is handled by
3803 build_target_list().
3804 (lookup_variable): Invoke handle_special_var().
3805 * file.c (build_target_list): Walk through the hask of known files
3806 and construct a list of the names of all the ones marked as
3808 * main.c (main): Initialize them to empty (and as simple variables).
3809 * doc/make.texi (Special Variables): Document them.
3810 * NEWS: Mention them.
3812 * variable.h (struct variable): Add a new flag "exportable" which
3813 is true if the variable name is valid for export.
3814 * variable.c (define_variable_in_set): Set "exportable" when a new
3815 variable is defined.
3816 (target_environment): Use the "exportable" flag instead of
3817 re-checking the name here... an efficiency improvement.
3819 2002-07-31 Paul D. Smith <psmith@gnu.org>
3821 * config.h-vms.template: Updates to build on VMS. Thanks to
3822 Brian_Benning@aksteel.com for helping verify the build.
3823 * makefile.com: Build the new hash.c file.
3824 * hash.h: Use strcpmi(), not stricmp(), in the
3825 HAVE_CASE_INSENSITIVE_FS case.
3827 2002-07-30 Paul D. Smith <psmith@gnu.org>
3829 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3830 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3831 Reported by <Brian_Benning@aksteel.com>.
3833 2002-07-10 Paul D. Smith <psmith@gnu.org>
3835 * variable.c (pop_variable_scope): Remove variable made unused by
3836 new hash infrastructure.
3837 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3838 comparisons as well as name comparisons.
3839 * variable.h: Add a prototype for new hash_init_function_table().
3840 * file.c (lookup_file): Remove variables made unused by new hash
3842 * dir.c (directory_contents_hash_2): Missing return of hash value.
3843 (dir_contents_file_exists_p): Remove variables made unused by new
3844 hash infrastructure.
3847 Installed Greg McGary's integration of the hash functions from the
3848 GNU id-utils package:
3850 2002-07-10 Greg McGary <greg@mcgary.org>
3852 * scripts/functions/filter-out: Add literals to to the
3853 pattern space in order to add complexity, and trigger
3854 use of an internal hash table. Fix documentation strings.
3855 * scripts/targets/INTERMEDIATE: Reverse order of files
3856 passed to expected `rm' command.
3858 2002-07-10 Greg McGary <greg@mcgary.org>

3950 2002-07-10 Paul D. Smith <psmith@gnu.org>
3952 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3953 prerequisite list. A real SysV make will expand the entire
3954 prerequisites list _twice_: we don't do that as it's a big
3955 backward-compatibility problem. We only replace those specific
3958 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3959 references left in the list of prerequisites. Check for .POSIX as
3960 we record targets, so we can disable non-POSIX behavior while
3961 reading makefiles as well as running them.
3962 (eval): Check the prerequisite list to see if we have anything
3963 that looks like a SysV prerequisite variable reference.
3965 2002-07-09 Paul D. Smith <psmith@gnu.org>
3967 * doc/make.texi (Prerequisite Types): Add a new section describing
3968 order-only prerequisites.
3970 * read.c (uniquize_deps): If we have the same file as both a
3971 normal and order-only prereq, get rid of the order-only prereq,
3972 since the normal one supersedes it.
3974 2002-07-08 Paul D. Smith <psmith@gnu.org>
3976 * AUTHORS: Added Greg McGary to the AUTHORS file.
3977 * NEWS: Blurbed order-only prerequisites.
3978 * file.c (print_file): Show order-only deps properly when printing
3981 * maintMakefile: Add "update" targets for wget'ing the latest
3982 versions of various external files. Taken from Makefile.maint in
3985 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3986 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3988 2002-07-07 Paul D. Smith <psmith@gnu.org>
3990 * po/*.po: Remove. We'll use wget to retrieve them at release
3993 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3994 rather than a shell you get an exception. Make sure we look up
3995 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3997 * remake.c (notice_finished_file): Fix handling of -t flag.
3998 Patch provided by Henning Makholm <henning@makholm.net>.
4000 * implicit.c (pattern_search): Some systems apparently run short
4001 of stack space, and using alloca() in this function caused an
4002 overrun. I modified it to use xmalloc() on the two variables
4003 which seemed like they might get large. Fixes Bug #476.
4005 * main.c (print_version): Update copyright notice to conform with
4007 (print_usage): Update help output.
4009 * function.c (func_eval): Create a new make function, $(eval
4010 ...). Expand the arguments, put them into a buffer, then invoke
4011 eval_buffer() on the resulting string.
4012 (func_quote): Create a new function, $(quote VARNAME). Inserts
4013 the value of the variable VARNAME without expanding it any
4016 * read.c (struct ebuffer): Change the linebuffer structure to an
4017 "eval buffer", which can be either a file or a buffer.
4018 (eval_makefile): Move the code in the old read_makefile() which
4019 located a makefile into here: create a struct ebuffer with that
4020 information. Have it invoke the new function eval() with that
4022 (eval_buffer): Create a new function that creates a struct ebuffer
4023 that holds a string buffer instead of a file. Have it invoke
4024 eval() with that ebuffer.
4025 (eval): New function that contains the guts of the old
4026 read_makefile() function: this function parses makefiles. Obtains
4027 data to parse from the provided ebuffer. Some modifications to
4028 make the flow of the function cleaner and clearer. Still could
4029 use some work here...
4030 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
4031 contents of the define/endef variable from the ebuffer.
4032 (readstring): Read the next line from a string-style ebuffer.
4033 (readline): Read the next line from an ebuffer. If it's a string
4034 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
4037 * dep.h (eval_buffer): Prototype eval_buffer();
4039 * variable.c (do_variable_definition): Make sure that all
4040 non-target-specific variables are registered in the global set.
4041 If we're invoked from an $(eval ...) we might be inside a $(call
4042 ...) or other function which has pushed a variable scope; we still
4043 want to define our variables from evaluated makefile code in the
4046 2002-07-03 Greg McGary <greg@mcgary.org>
4048 * dep.h (struct dep) [ignore_mtime]: New member.
4049 [changed]: convert to a bitfield.
4050 * implicit.c (pattern_search): Zero ignore_mtime.
4051 * main.c (main, handle_non_switch_argument): Likewise.
4052 * rule.c (convert_suffix_rule): Likewise.
4053 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
4054 (read_makefile): Parse '|' in prerequisite list.
4055 (uniquize_deps): Consider ignore_mtime when comparing deps.
4056 * remake.c (update_file_1, check_dep): Don't force remake for
4057 dependencies that have d->ignore_mtime.
4058 * commands.c (FILE_LIST_SEPARATOR): New constant.
4059 (set_file_variables): Don't include a
4060 prerequisite in $+, $^ or $? if d->ignore_mtime.
4063 2002-06-18 Paul D. Smith <psmith@gnu.org>
4065 * make.texinfo: Updates for next revision. New date/rev/etc.
4066 Recreate all Info menus. Change license on the manual to the GNU
4067 Free Documentation License. A number of typos.
4068 (Variables Simplify): Don't use "-" before it's defined.
4069 (Automatic Prerequisites): Rewrite the target example to work
4070 properly if the compile fails. Remove incorrect comments about
4071 how "set -e" behaves.
4072 (Text Functions): Move the "word", "wordlist", "words", and
4073 "firstword" functions here, from "File Name Functions".
4074 * make-stds.texi: Update from latest GNU version.
4075 * fdl.texi: (created) Import the latest GNU version.
4077 2002-06-06 Paul D. Smith <psmith@gnu.org>
4079 * variable.c (do_variable_definition): New function: extract the
4080 part of try_variable_definition() that actually sets the value
4081 into a separate function.
4082 (try_variable_definition): Call do_variable_definition() after
4083 parsing the variable definition string.
4084 (define_variable_in_set): Make the name argument const.
4086 * variable.h (enum variable_flavor): Make public.
4087 (do_variable_definition): Create prototype.
4089 * read.c (read_all_makefiles): Create a new built-in variable,
4091 (read_makefile): Add each makefile read in to this variable value.
4093 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4095 * Makefile.DOS.template: Tweak according to changes in the
4096 distribution. Add back the dependencies of *.o files.
4098 * configh.dos.template: Synchronize with config.h.in.
4100 2002-05-09 Paul D. Smith <psmith@gnu.org>
4102 * file.c (file_timestamp_now): Use K&R function declaration.
4104 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4105 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4106 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4107 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4108 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4109 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4110 nlist.n_name is a pointer rather than an array.
4112 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4113 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4114 * configure.in: Use it instead of the old version.
4116 * main.c (main): Prefer setvbuf() to setlinebuf().
4118 2002-05-08 Paul D. Smith <psmith@gnu.org>
4120 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4121 (loadavg_LDADD): Ditto.
4123 2002-04-29 Paul D. Smith <psmith@gnu.org>
4125 * expand.c (recursively_expand_for_file): Rename
4126 recursively_expand() to recursively_expand_for_file() and provide
4127 an extra argument, struct file. If the argument is provided, set
4128 the variable scope to that of the file before expanding.
4129 * variable.h (recursively_expand): Make this a macro that invokes
4130 recursively_expand_for_file() with a NULL file pointer.
4131 * variable.c (target_environment): Call the renamed function and
4132 provide the current file context.
4133 Fixes Debian bug #144306.
4135 2002-04-28 Paul D. Smith <psmith@gnu.org>
4137 Allow $(call ...) user-defined variables to be self-referencing
4138 without throwing an error. Allows implementation of transitive
4139 closures, among other possibly useful things.
4140 Requested by: Philip Guenther <guenther@sendmail.com>
4142 * variable.h (struct variable): Add a new field: exp_count, and
4143 new macros to hold its size and maximum value.
4144 (warn_undefined): Make this a macro.
4145 * variable.c (define_variable_in_set): Initialize it.
4146 * expand.c (recursively_expand): If we detect recursive expansion
4147 of a variable, check the exp_count field. If it's greater than 0
4148 allow the recursion and decrement the count.
4149 (warn_undefined): Remove this (now a macro in variable.h).
4150 * function.c (func_call): Before we expand the user-defined
4151 function, modify its exp_count field to contain the maximum
4152 number of recursive calls we'll allow. After the call, reset it
4155 2002-04-21 Paul D. Smith <psmith@gnu.org>
4157 Modified to use latest autoconf (2.53), automake (1.6.1), and
4158 gettext (0.11.1). We're using gettext's new "external" support,
4159 to avoid including libintl source with GNU make.
4161 * README.cvs: New file. Explain how to build GNU make from CVS.
4163 * configure.in: Modify checking for the system glob library.
4164 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4165 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4166 etc. will manage it correctly). Set an automake conditional
4167 USE_LOCAL_GLOB to decide whether to compile the glob library.
4169 * getloadavg.c (main): Include make.h in the "TEST" program to
4172 * Makefile.am: Remove special rules for loadavg. Replace them
4173 with Automake capabilities for building extra programs.
4175 * signame.c: This file does nothing if the system provide
4176 strsignal(). If not, it implements strsignal(). If the system
4177 doesn't define sys_siglist, then we make our own; otherwise we use
4179 * signame.h: Removed.
4181 * main.c (main): No need to invoke signame_init(). Update copyright.
4183 * ABOUT-NLS: Removed.
4184 * gettext.c: Removed.
4185 * gettext.h: Get a simplified copy from the gettext package.
4187 * i18n/*.po: Moved to po/.
4190 * config/*: Created. Contains package configuration helper files.
4191 * config.guess, config.sub: Moved to config directory.
4193 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4194 Rework to use new-style autoconf features. Use the "external"
4195 mode for gettext. Make the build.sh config file conditional on
4196 whether build.sh.in exists, to avoid autoconf errors.
4197 * acinclude.m4: Removed almost all macros as being obsolete.
4198 Rewrote remaining macros to use AC_DEFINE.
4199 * acconfig.h: Removed.
4201 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4202 conditional to handle customs support. Remove special handling
4205 2002-04-20 Paul D. Smith <psmith@gnu.org>
4207 * function.c (func_call): Don't mark the argument variables $1,
4208 etc. as recursive. They've already been fully expanded so
4209 there's no need to do it again, and doing so strips escaped $'s.
4210 Reported by Sebastian Glita <glseba@yahoo.com>.
4212 * remake.c (notice_finished_file): Walk through double-colon
4213 entries via the prev field, not the next field!
4214 Reported by Greg McGary <greg@mcgary.org>.
4216 * main.c (main): If the user specifies -q and asks for a specific
4217 target which is a makefile, we got an assert. In that case it
4218 turns out we should continue normally instead.
4220 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4222 * i18n/he.po: Installed a new translation.
4224 2002-01-07 Paul D. Smith <psmith@gnu.org>
4226 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4228 2001-12-04 Paul D. Smith <psmith@gnu.org>
4230 * i18n/ja.po: Installed an updated translation.
4232 2001-09-06 Paul Eggert <eggert@twinsun.com>
4234 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4235 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4237 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4239 (main): Get rid of any avoidable limit on stack size.
4241 2001-09-04 Paul D. Smith <psmith@gnu.org>
4243 * i18n/da.po: Installed an updated translation.
4245 2001-08-03 Paul D. Smith <psmith@gnu.org>
4247 * i18n/fr.po: Installed an updated translation.
4248 Resolves Debian bug #106720.
4250 2001-06-13 Paul D. Smith <psmith@gnu.org>
4252 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4255 2001-06-11 Paul D. Smith <psmith@gnu.org>
4257 * i18n/ko.po: Installed a new translation.
4259 2001-05-06 Paul D. Smith <psmith@gnu.org>
4261 Modify the EINTR handling.
4263 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4264 the way in which we manage the file descriptor/signal handler race
4265 trap to be more efficient.
4267 2001-05-06 Paul Eggert <eggert@twinsun.com>
4269 Restart almost all system calls that are interrupted, instead
4270 of worrying about EINTR. The lone exception is the read() for
4273 * configure.in (HAVE_SA_RESTART): New macro.
4274 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4275 * main.c (main): Use SA_RESTART instead of the old,
4276 nonstandard SA_INTERRUPT.
4278 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4279 * main.c (bsd_signal): New function or macro,
4280 if the implementation doesn't supply it.
4281 (The bsd_signal function will be in POSIX 1003.1-200x.)
4282 (HANDLESIG): Remove.
4283 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4285 * make.h (EINTR_SET): Remove.
4286 (SA_RESTART): New macro.
4288 * arscan.c (ar_member_touch): Don't worry about EINTR.
4289 * function.c (func_shell): Likewise.
4290 * job.c (reap_children, free_child, new_job): Likewise.
4291 * main.c (main): Likewise.
4292 * remake.c (touch_file, name_mtime): Likewise.
4294 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4295 if fstat failed with errno!=EINTR, the error was ignored.
4297 * job.c (set_child_handler_action_flags): New function.
4298 (new_job): Use it to temporarily clear the SIGCHLD action flags
4299 while reading the token.
4301 2001-05-02 Paul D. Smith <psmith@gnu.org>
4303 * job.c (start_job_command): Don't add define/endef per-line flags
4304 to the top-level flags setting.
4306 2001-04-03 Paul D. Smith <psmith@gnu.org>
4308 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4309 bit on error, so check for odd return values, not non-0 return
4311 (VMS_get_member_info): Calculate the timezone differences correctly.
4312 Reported by John Fowler <jfowler@nyx.net>.
4315 2001-03-14 Paul D. Smith <psmith@gnu.org>
4317 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4318 value before invoking define_variable().
4319 Reported by John Fowler <jfowler@nyx.net>.
4321 2001-02-07 Paul D. Smith <psmith@gnu.org>
4323 * read.c (record_target_var): If we reset the variable due to a
4324 command-line variable setting overriding it, turn off the "append"
4327 2001-01-17 Paul D. Smith <psmith@gnu.org>
4329 * variable.c (lookup_variable) [VMS]: When getting values from the
4330 environment, allocate enough space for the _value_ plus escapes,
4331 not enough space for the name plus escapes :-/.
4332 Reported by John Fowler <jfowler@nyx.net>.
4334 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4335 warnings that make generates, so it doesn't look like an error.
4336 Reported by Karl Berry <karl@gnu.org>.
4339 Fix for PR/2020: Rework appended target-specific variables. I'm
4340 fairly confident this algorithm is finally correct.
4342 * expand.c (allocated_variable_append): Rewrite. Instead of
4343 expanding each appended variable then adding all the expanded
4344 strings together, we append all the unexpanded values going up
4345 through the variable set contexts, then expand the final result.
4346 This behaves just like non-target-specific appended variable
4347 values, while the old way didn't in various corner cases.
4348 (variable_append): New function: recursively append the unexpanded
4349 value of a variable, walking from the outermost variable scope to
4351 * variable.c (lookup_variable): Remove the code that looked up the
4352 variable set list if the found variable was "append". We don't
4354 (lookup_variable_in_set): Make this non-static so we can use it
4356 (try_variable_definition): Use lookup_variable_in_set() rather
4357 than faking out current_variable_set_list by hand (cleanup).
4358 * variable.h: Add a prototype for the now non-static
4359 lookup_variable_in_set().
4361 2000-11-17 Paul D. Smith <psmith@gnu.org>
4363 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4364 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4365 before throwing a fit.
4367 2000-11-17 Paul D. Smith <psmith@gnu.org>
4369 * read.c (readline): CRLF calculations had a hole, if you hit the
4370 buffer grow scenario just right. Reworked the algorithm to avoid
4371 the need for len or lastlen at all. Problem description with
4372 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4374 2000-10-24 Paul D. Smith <psmith@gnu.org>
4376 * gettext.c (SWAP): Declare this with the prototype, otherwise
4377 some systems don't work (non-32-bit? Reported for Cray T3E).
4378 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4380 2000-10-05 Paul D. Smith <psmith@gnu.org>
4382 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4383 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4385 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4387 2000-09-22 Paul D. Smith <psmith@gnu.org>
4389 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4390 parts of the real gettext.h here, and we expect to really include
4391 the real gettext.h later. If we keep this #define, it's ignored.
4393 2000-09-21 Paul D. Smith <psmith@gnu.org>
4395 * main.c (log_working_directory): Rework the text to use complete
4396 sentences, to make life simpler for the translators.
4398 2000-08-29 Paul D. Smith <psmith@gnu.org>
4400 * file.c (remove_intermediates): Print a debug message before we
4401 remove intermediate files, so the user (if she uses -d) knows
4404 2000-08-21 Paul D. Smith <psmith@gnu.org>
4406 * variable.c (try_variable_definition): Change how we handle
4407 target-specific append variable defns: instead of just setting the
4408 value, expand it as an append _but_ only within the current
4409 target's context. Otherwise we lose all but the last value if the
4410 variable is appended more than once within the current target
4411 context. Fixes PR/1831.
4413 2000-08-16 Paul D. Smith <psmith@gnu.org>
4415 * function.c (func_shell): Nul-terminate the buffer before
4416 printing an exec error message (just in case it's not!).
4417 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4419 2000-07-25 Paul D. Smith <psmith@gnu.org>
4421 * job.c (construct_command_argv_internal): Add "~" to the list of
4422 sh_chars[] which disallow optimizing out the shell call.
4424 2000-07-23 Paul Eggert <eggert@twinsun.com>
4426 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4427 supersedes --disable-nsec-timestamps.
4428 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4429 * README: Remove --disable-nsec-timestamps.
4431 * filedef.h (struct file.low_resolution_time): New member.
4432 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4433 * remake.c (update_file_1):
4434 Avoid spurious rebuilds due to low resolution time stamps,
4435 generalizing the earlier code that applied only to archive members.
4436 (f_mtime): Archive members always have low resolution time stamps.
4438 * configure.in: Remove --disable-nsec-timestamps, as this has
4439 been superseded by .LOW_RESOLUTION_TIME.
4441 2000-07-23 Paul Eggert <eggert@twinsun.com>
4443 * configure.in (enable_nsec_timestamps): Renamed from
4444 make_cv_nsec_timestamps, since enable/disable options
4445 shouldn't be cached.
4447 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4448 and Paul Eggert <eggert@twinsun.com>
4450 * file.c (file_timestamp_now):
4451 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4452 so that clock_gettime is not linked unless needed.
4454 * filedef.h (FILE_TIMESTAMP_HI_RES):
4455 Remove definition; "configure" now does this.
4457 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4458 to before high resolution file timestamp check,
4459 since that check now uses uintmax_t.
4460 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4461 high resolution file timestamps.
4462 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4463 so that we don't link in clock_gettime unnecessarily.
4465 2000-07-17 Paul D. Smith <psmith@gnu.org>
4467 * i18n/ja.po: New version of the translation file.
4469 2000-07-07 Paul D. Smith <psmith@gnu.org>
4471 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4472 the offset calculation.
4473 (name_mtime): Replace EINTR test with EINTR_SET macro.
4475 2000-07-07 Paul Eggert <eggert@twinsun.com>
4479 * remake.c (update_file_1):
4480 Avoid spurious rebuilds of archive members due to their
4481 timestamp resolution being only one second.
4482 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4483 the clock's resolution being lower than file timestamps'.
4484 When warning about future timestamps, report only the discrepancy,
4485 not the absolute value of the timestamp and the current time.
4487 * file.c (file_timestamp_now): New arg RESOLUTION.
4488 * filedef.h (file_timestamp_now): Likewise.
4489 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4491 2000-07-05 Paul D. Smith <psmith@gnu.org>
4493 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4494 to listp. Fixes PR/1793.
4496 2000-06-26 Paul Eggert <eggert@twinsun.com>
4498 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4500 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4502 * remake.c (f_mtime): Remove unused var memtime.
4504 2000-06-25 Martin Buchholz <martin@xemacs.org>
4506 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4507 Ran spell-check on make.texinfo.
4509 2000-06-23 Paul D. Smith <psmith@gnu.org>
4511 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4512 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4513 * make.h: Define these macros.
4515 * Version 3.79.1 released.
4517 * configure.in: Add a new option, --disable-nsec-timestamps, to
4518 avoid using sub-second timestamps on systems that support it. It
4519 can lead to problems, e.g. if your makefile relies on "cp -p".
4520 * README.template: Document the issue with "cp -p".
4522 * config.guess, config.sub: Updated.
