552 and pass it to construct_command_argv_internal().
553 (construct_command_argv_internal): If .SHELLFLAGS is non-standard

571 2010-07-03 Paul Smith <psmith@gnu.org>
573 * read.c (parse_file_seq): All archive groups must end with ')' as
574 the LAST character in a word. If there is no word ending in ')'
575 then it's not an archive group. Fixes Savannah bug #28525.
577 2010-07-01 Paul Smith <psmith@gnu.org>
579 * main.c (main): Append optional features using separate calls.

633 * vpath.c (vpath_search, selective_vpath_search): Add index arguments
634 which allows the caller to get the index of the matching directory.
636 * make.h (vpath_search): Update prototype.
638 * remake.c (library_search): Implement linker-compatible library
639 search. Use the new VPATH_SEARCH index functionality to keep track

641 lowest directory index.
643 * implicit.c (pattern_search): Pass NULL for the index arguments in
644 the VPATH_SEARCH call.
646 * doc/make.texi (Directory Search for Link Libraries): Describe the

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

733 * implicit.c (pattern_search): Initialize file variables only
734 if we need to parse a rule that requires the second expansion.
736 2009-10-03 Paul Smith <psmith@gnu.org>
738 * make.h: Include <alloca.h> even on systems where __GNUC__ is
739 defined. Not sure why it was done the other way.

746 * filedef.h (file):Add the NO_DIAG bitfield.
748 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,

750 some don't care, some do).
752 * remake.c (update_goal_chain): Propagate DONTCARE from struct
753 dep to struct file before updating the goal and restore it
755 (update_file): Don't prune the dependency graph if this target
756 has failed but the diagnostics hasn't been issued.
757 (complain): Scan the file's dependency graph to find the file
758 that caused the failure.
759 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
760 whether to print diagnostics.
762 Fixes Savannah bugs #15110, #25493, #12686, and #17740.

797 * doc/make.texi (Double-Colon): Mention that pattern rules with
798 double-colons have a different meaning. Savannah bug #27497.
800 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
802 * configh.dos.template: Remove unconditional definition of
803 SYS_SIGLIST_DECLARED.
804 Include <sys/version.h> because ports of GCC 4.3.0 and later no
805 longer include it, so macros like __DJGPP_MINOR__ are no longer
806 defined automatically.
808 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
809 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
810 instead of using the hardcoded ones.
811 (SUBDIRS): doc subdir added.
812 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
813 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
814 create html formated docs. texi2html may not be ported to DOS.
815 (make.info, make.dvi, make.ps, make.html): Make targets depend on
817 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
818 -I switch to look in ./ instead of ./doc.
819 (html): Target depend on html-recursive instead of make_1.html.
820 (make_1.html): Removed.
821 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
822 (all-recursive): Allow for more than one subdir in the build
824 (mostlyclean-recursive, clean-recursive, distclean-recursive)
825 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
826 (tags-recursive): Allow for more than one subdir in the build
828 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
829 targets. Enter into doc/ to produce the targets.
830 (all-am): $(INFO_DEPS) replaced by info.
832 2009-09-26 Paul Smith <psmith@gnu.org>
834 * read.c (record_files): Use free_ns() to free struct nameseq.
837 * rule.c (freerule): Use free_dep_chain().
839 * read.c (record_files): Free FILENAMES chain for implicit rules.
840 (eval): Static pattern targets go into the string cache.
842 * function.c (string_glob): Free NAME in the nameseq chain.
844 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
846 * implicit.c (pattern_search): Terminate early if we haven't
847 found any rules to try (performance improvement).
849 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
851 * implicit.c (pattern_search): Merge three parallel arrays,
852 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
853 of struct TRYRULE. In the old version the latter two arrays
854 had insufficient length.
856 2009-09-24 Paul Smith <psmith@gnu.org>
858 * implicit.c (pattern_search): Add back support for order-only
859 prerequisites for secondary expansion implicit rules, that were
860 accidentally dropped. If we find a "|", enable order-only mode
861 and set IGNORE_MTIME on all deps that are seen afterward.
862 (pattern_search): Fix memory leaks: for intermediate files where
863 we've already set the file variable and pattern variable sets, be
864 sure to either save or free them as appropriate.
866 2009-09-23 Paul Smith <psmith@gnu.org>
868 Rework the way secondary expansion is stored, for efficiency.
869 This changes secondary expansion so that ONLY WHEN we know we have
870 a possibility of needing secondary expansion, do we defer the
871 secondary expansion. This means more parsing the deps but we use
872 a lot less memory (due to the strcache). Also, this fixes
875 * read.c (eval): Don't parse the dep string here anymore.
876 (record_files): Take the dep argument as an unparsed string. If
877 secondary expansion is enabled AND the prereq string has a '$' in
878 it, then set NEED_2ND_EXPANSION and keep the entire string.
879 Otherwise, parse the dep string here to construct the dep list
880 with the names in the strcache.
882 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
883 duplicate the name string (others are in the strcache).
885 * implicit.c: Remove struct idep and free_idep_chain(): unused.
886 (struct patdeps): New structure to store prereq information.
887 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
888 which prerequisites need expansion, and expand only those.
890 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
891 and enter_prereqs(). split_prereqs() takes a fully-expanded string
892 and splits it into a DEP list, handling order-only prereqs.
893 (enter_prereqs): This function enters a list of DEPs into the file
894 database. If there's a stem defined, expand any pattern chars.
895 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
896 set. Use the above functions.
897 (snap_deps): Only perform second expansion on prereqs that need it,
898 as defined by the NEED_2ND_EXPANSION flag.
899 (print_prereqs): New function to print the prereqs
900 (print_file): Call print_prereqs() rather than print inline.
902 * hash.h (STRING_COMPARE): Take advantage of strcache() by
904 (STRING_N_COMPARE): Ditto.
905 (ISTRING_COMPARE): Ditto.
907 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
908 (parse_file_seq): Return void*
909 * read.c (parse_file_seq): Return void*.
910 (eval): Invoke macroized version of parse_file_seq()
911 * default.c (set_default_suffixes): Ditto.
912 * file.c (split_prereqs): Ditto.
913 * function.c (string_glob): Ditto.
914 * main.c (main): Ditto.
915 * rule.c (install_pattern_rule): Ditto.
917 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
919 2009-09-16 Paul Smith <psmith@gnu.org>
921 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
923 * dep.h: Create alloc_dep() / free_dep() macros.
925 * implicit.c (pattern_search): Take advantage of the new
926 parse_file_seq() to add the directory prefix to each prereq.
928 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
929 all. Avoid reversing chains. Support adding prefixes.
930 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
931 cached/non-cached results.
932 (eval): Remove multi_glob() & invoke new parse_file_seq().
933 * rule.c (install_pattern_rule): Ditto.
934 * main.c (main): Ditto.
935 * implicit.c (pattern_search): Ditto.
936 * function.c (string_glob): Ditto.
937 * file.c (parse_prereqs): Ditto.
938 * default.c (set_default_suffixes): Ditto.
940 * variable.c (parse_variable_definition): Don't run off the end of
941 the string if it ends in whitespace (found with valgrind).
943 * commands.c (set_file_variables): Keep space for all targets in
944 $? if -B is given (found with valgrind).
946 2009-09-15 Paul Smith <psmith@gnu.org>
948 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
949 (xcalloc): Add new function.
950 * make.h: New declarations.
952 * ar.c (ar_glob_match): New calling method for concat().
953 * main.c (main): Ditto.
954 (decode_env_switches): Ditto.
955 * read.c (eval_makefile): Ditto.
956 (tilde_expand): Ditto.
957 (parse_file_seq): Ditto.
958 * variable.c (target_environment): Ditto.
959 (sync_Path_environment): Ditto.
961 * ar.c (ar_glob_match): Use xcalloc().
962 * dir.c (file_impossible): Ditto.
963 * file.c (enter_file): Ditto.
964 * job.c (new_job): Ditto.
965 * read.c (parse_file_seq): Ditto.
966 * vmsfunctions.c (opendir): Ditto.
968 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
970 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
971 inside the loop that looks up environment for PATH.
973 2009-08-31 Eli Zaretskii <eliz@gnu.org>

976 sync_Path_environment.
978 2009-08-02 Paul Smith <psmith@gnu.org>

981 before looping through them. Fixes Savannah bug #21824.
983 * doc/make.texi (Wildcard Examples): Clarify when objects is
984 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
985 (Include): Clarify the behavior of -include.
986 Fixes Savannah bug #18963.
988 2009-08-01 Paul Smith <psmith@gnu.org>
990 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
991 etc. come on the command line. Fixes Savannah bug #27093.
993 * expand.c (expand_argument): If the argument is large enough use
994 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
996 * variable.c (do_variable_definition): Avoid using alloca() to
997 hold values, which can be large. Fixes Savannah bug #23960.
999 * job.c (new_job): Use memmove() instead of strcpy() since both
1000 pointers are in the same memory block. Fixes Savannah bug #27148.
1001 Patch by Petr Machata.
1003 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1005 * job.c (construct_command_argv_internal): Add "ulimit" and
1006 "unset" to the sh_cmds for Unixy shells.
1008 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1010 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1011 that set make_cv_sys_gnu_glob, so they are also correctly set
1012 when the cache has been populated before.
1014 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1016 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1017 exist, as realpath(3) does where it's supported.
1019 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1021 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1022 (abspath): Support systems that define HAVE_DOS_PATHS (have
1023 drive letters in their file names). Use IS_PATHSEP instead of a
1024 literal '/' comparison. Fixes Savannah bug #26886.
1026 2009-06-14 Paul Smith <psmith@gnu.org>
1028 * remake.c (update_file_1): Remember the original file we marked
1029 as updating, so we can clear that flag again. If we find a target
1030 via vpath, FILE might change.
1031 (check_dep): Ditto. Fixes Savannah bug #13529.
1032 Patch by Reid Madsen <reid.madsen@tek.com>.
1034 2009-06-13 Paul Smith <psmith@gnu.org>
1036 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1037 included by MAKEFILES cannot give default goals.
1038 * read.c (eval): If set_default is not set, pass the no-default-goal
1039 value when we read included makefiles. Fixes Savannah bug #13401.
1041 * ar.c (ar_name): Ensure that targets with empty parens aren't
1042 considered archive member references: archive members must have a
1043 non-empty "member" string. Fixes Savannah bug #18435.
1045 * function.c (string_glob): Rely on multi_glob() to determine
1046 whether files exist or not. Remove call to file_exists_p() which
1047 is not always correct. Fixes Savannah bug #21231.
1048 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1049 then only files that really exist will be returned.
1050 * dep.h: Add new argument to multi_glob().
1051 * rule.c (install_pattern_rule): Ditto.
1052 * read.c (eval): Ditto.

1061 always add the prereq to $?. Fixes Savannah bug #17825.
1063 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1064 to rebuild the deps of all the also_make targets for that file.
1065 Fixes Savannah bug #19108.
1067 * implicit.c (pattern_search): Undo test for is_target, added by
1068 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1069 Rule Search Algorithm". Fixes Savannah bug #17752.
1071 * main.c (clean_jobserver): Clear the jobserver_fds options and
1072 set job_slots to the default when we clean up.
1073 (define_makeflags): Return the new MAKEFLAGS value.
1074 (main): Reset MAKEFLAGS in the environment when we re-exec.
1075 Fixes Savannah bug #18124.
1077 2009-06-08 Paul Smith <psmith@gnu.org>
1079 * read.c (eval): Collapse continuations post-semicolon on target-
1080 specific variables. Fixes Savannah bug #17521.
1082 2009-06-07 Paul Smith <psmith@gnu.org>
1084 * job.c (reap_children): For older systems without waitpid() (are
1085 there any of these left?) run wait(2) inside EINTRLOOP to handle
1086 EINTR errors. Fixes Savannah bug #16401.
1088 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1090 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1092 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1093 not the end, to catch second expansion $(eval ...) defining new
1094 target/prereq relationships during snap_deps.
1095 Fixes Savannah bug #24622.
1097 * read.c (record_files): The second-expansion "f->updating" hack
1098 was not completely correct: if assumed that the target with
1099 commands always had prerequisites; if one didn't then the ordering
1100 was messed up. Fixed for now to use f->updating to decide whether
1101 to preserve the last element in the deps list... but this whole
1102 area of constructing and reversing the deps list is too confusing
1103 and needs to be reworked. Fixes Savannah bug #21198.
1105 2009-06-06 Paul Smith <psmith@gnu.org>
1107 * hash.c (hash_insert): Remove useless test for NULL.
1108 Fixes Savannah bug #21823.
1110 * make.h: Move SET_STACK_SIZE determination to make.h.
1111 * main.c (main): New global variable, STACK_LIMIT, holds the
1112 original stack limit when make was started.
1113 * job.c (start_job_command): Reset the stack limit, if we changed it.
1114 Fixes Savannah bug #22010.
1116 * remake.c (check_dep): Only set the target's state to not-started
1117 if it's not already running. Found this while testing -j10 builds
1118 of glibc: various targets were being rebuilt multiple times.
1119 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1122 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1123 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1126 2009-06-04 Paul Smith <psmith@gnu.org>
1128 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1130 * maintMakefile: Modify access of config and gnulib Savannah
1131 modules to use GIT instead of CVS.
1133 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1134 Fixes Savannah bug #24655.
1136 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1137 this can happen during some invocations of $(eval ...) for example.
1138 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1140 2009-06-02 Paul Smith <psmith@gnu.org>
1142 * configure.in: Check for fileno()
1143 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1144 for the makefile file so invocations of $(shell ...) don't inherit it.
1145 Fixes Savannah bug #24277.
1147 2009-06-01 Paul Smith <psmith@gnu.org>
1149 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1150 expansion was handled incorrectly. Rework the default goal
1151 handling to save the variable only. Remove default_goal_file and
1153 * read.c (eval): Check default_goal_var, not default_goal_name.
1154 * read.c (record_target_var): Don't check default_goal_file here.
1156 2009-05-31 Paul Smith <psmith@gnu.org>
1158 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1159 it, and if the multi_glob() returns nothing (say it expanded to
1160 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1162 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1163 $(and ..) to the reference. Fixes Savannah bug #25694.
1165 * make.1: Be clear that some recipes will be executed even with -n.
1166 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1168 * doc/make.texi (Override Directive): Make more clear how
1169 overrides and appends interact.
1170 Elucidates part of Savannah bug #26207.
1172 * read.c (record_target_var): Don't reset the origin on
1173 target-specific variables; try_variable_definition() will handle
1174 this correctly. Fixes Savannah bug #26207.
1176 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1177 Fixes Savannah bug #25712.
1179 * implicit.c (pattern_search): Keep a pointer to the beginning of
1180 the filename and save that instead of the constructed pointer.
1181 Fixes Savannah bug #26593.
1182 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1184 2009-05-30 Paul Smith <psmith@gnu.org>
1186 * doc/make.texi (Multi-Line): Add a description of the new abilities
1187 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1188 "command sequence" vs. "recipe" syntax.
1189 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1190 after a define, to create variables with those flavors.
1192 2009-05-25 Paul Smith <psmith@gnu.org>
1194 Reworked the parser for variable assignments to allow multiple
1195 modifiers, and in any order. Also allows variable and
1196 prerequisites to be modifier names ('export', 'private', etc.)
1198 * NEWS: Add notes about user-visible changes.
1200 * read.c (struct vmodifiers): Remember what modifiers were seen.
1201 (parse_var_assignment): New function to parse variable assignments.
1202 (eval): Call the new function. Handle variable assignments earlier.
1204 * variable.c (parse_variable_definition): Only parse; don't create var.
1205 (assign_variable_definition): Call parse, then create the var.
1207 2009-05-24 Paul Smith <psmith@gnu.org>
1209 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1210 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1212 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1214 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1215 Fixes Savannah bug #25412.
1217 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1218 prototype for xmalloc.
1219 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1220 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1221 Loop over an array of extensions, instead of duplicating the same
1222 code inline. Use SearchPath followed by CreateFile, instead of
1223 the obsolete OpenFile. Fixes Savannah bug #17277.
1224 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1225 to `find_file'. Fixes Savannah bug #25662.
1227 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1229 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1230 Fixes Savannah bug #20495.
1232 2009-02-28 Ralf Wildenhues <address@hidden>
1234 * doc/make.texi (Instead of Execution): Document interaction of
1235 -t with phony targets.
1237 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1239 Introduce a new keyword "private" which applies to target-specific
1240 variables and prevents their values from being inherited.
1242 * variable.h (struct variable): Add private_var flag to each variable.
1243 Add a flag to specify which list entry switches to the parent target.
1244 * variable.c (define_variable_in_set): Initialize private_var flag.
1245 (lookup_variable): Skip private variables in parent contexts.
1246 (initialize_file_variables): Set next_is_parent appropriately.

1248 * read.c (eval): Recognize the private keyword.
1249 (record_target_var): Set private_var.
1250 * doc/make.texi (Suppressing Inheritance): Add documentation.
1252 2008-10-26 Paul Smith <psmith@gnu.org>
1254 * configure.in: Check for strndup().
1255 * misc.c (xstrndup): Rename savestring to xstrndup. Use strndup
1257 * make.h: Rename savestring to xstrndup.
1258 * commands.c (chop_commands): Ditto.
1259 * function.c (func_foreach): Ditto.
1260 * read.c (eval, record_files): Ditto.
1261 * variable.c (define_variable_in_set): Ditto.
1263 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1265 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1268 * w32/subproc/build.bat (GCCBuild): Likewise.
1270 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1272 * job.c (construct_command_argv_internal): Avoid extra backslash
1273 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1276 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1278 * README.W32.template: Remove obsolete text about non-support for
1279 -jN without Unixy shell. Remove obsolete text about not supplying
1280 Visual Studio project files (we do supply them). Modify text to
1281 prefer GCC builds to MSC builds.
1283 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1285 * doc/make.texi (Empty Targets): Fix typo.
1287 2008-03-27 Paul Smith <psmith@gnu.org>
1289 Fix Savannah bug #22379:
1290 * ar.c (ar_glob_match): Zero the allocated structure.

1293 2008-03-08 Brian Dessent <brian@dessent.net>
1295 * maintMakefile: Update Translation Project location.
1297 2008-01-26 Eli Zaretskii <eliz@gnu.org>
1299 * variable.c (target_environment): Don't use shell_var if its
1300 `value' field is NULL.
1302 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1304 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1306 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1307 (TEXINFOS): Value changed to `doc/make.texi'.
1308 (.SUFFIXES): Use .texi instead of .texinfo.
1309 (make.info, make.dvi): Depend on doc/make.texi.
1310 (.texi.info): New target, instead of ".texinfo.info". Change -I
1311 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1312 (.texi): New target, instead of ".texinfo". Change -I switch to
1313 $(MAKEINFO) to look in doc/. Use --no-split.
1314 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1315 switch to $(MAKEINFO) to look in doc/.
1316 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1317 "*.i[0-9][0-9]" (due to --no-split above).
1318 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1319 (html, make_1.html): New targets.
1320 (.PHONY): Add "html".
1321 (.SUFFIXES): Add .html.
1323 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1325 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1326 HAVE_DECL_SYS_SIGLIST.
1328 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1329 build does not use child_execute_job.
1331 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1332 export the SHELL environment variable to the child.
1334 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1336 * config.h.W32: Include sys/types.h.
1337 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1339 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
1340 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
1343 2007-11-04 Paul Smith <psmith@gnu.org>
1345 * doc/make.texi: Convert references to "commands", "command
1346 lines", and "command script" to "recipe".
1348 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
1351 2007-10-27 Bruno Haible <bruno@clisp.org>
1353 * remake.c (f_mtime): Print time difference values between 100 and
1354 ULONG_MAX in fixed-point notation rather than in exponention notation.
1356 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1358 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1359 a more complex value than a simple shell: if it's not a default
1360 shell now then expand it and see if is a default shell then.
1362 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1364 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1365 pathnames, with const strings.
1366 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1367 from the template (used for building from CVS, not a dist).
1369 2007-10-10 Paul Smith <psmith@gnu.org>
1371 * make.h: Add a prototype for w32_kill() (change suggested by
1372 Yongwei Wu <wuyongwei@gmail.com>).
1374 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1376 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1377 directories in Path.
1379 2007-09-12 Paul Smith <psmith@gnu.org>
1381 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
1382 Provided by Diego Biurrun <diego@biurrun.de>
1383 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1384 Provided by Diego Biurrun <diego@biurrun.de>
1386 2007-09-11 Paul Smith <psmith@gnu.org>
1388 * doc/make.texi (Special Variables): Moved this into the "How to
1389 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1390 (MAKEFILE_LIST) No longer a section; this was added into the
1391 "Special Variables" section.
1392 (Rule Introduction): Reference .RECIPEPREFIX.
1393 (Simple Makefile): Ditto.
1394 (Rule Syntax): Ditto.
1395 (Command Syntax): Ditto.
1396 (Error Messages): Ditto.
1398 2007-09-10 Paul Smith <psmith@gnu.org>
1400 * commands.c (print_commands): Don't print an extra line in the
1401 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1403 * read.c (construct_include_path): Add the full string to the cache; we
1404 were chopping the last char.
1406 * NEWS: Announce the .RECIPEPREFIX special variable.
1407 * variable.c (lookup_special_var): Rename from handle_special_var().
1408 (lookup_variable): Call the new name.
1409 (set_special_var): New function: handle setting of special variables.
1410 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1411 (do_variable_definition): Call it.
1412 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1413 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1414 * main.c (main): Create the .RECIPEPREFIX special variable.
1415 * read.c (eval): Remove the cmd_prefix characters from the command
1416 scripts here, so they're not stored in the commands array at all,
1417 rather than waiting and stripping them out during command construction.
1418 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1420 2007-08-15 Paul Smith <psmith@gnu.org>
1422 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1423 file has had the section info removed, so add some to make.texi
1424 before we include it.
1426 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1428 * remake.c (check_dep): Reset the target state for intermediate
1429 files. They might have been considered before but not updated
1430 then (order-only for example) but they will be this time.
1431 Fixes Savannah bug #'s 3330 and 15919.
1433 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1435 Fix Savannah bug #20549:
1436 * function.c (func_shell): Call construct_command_argv with zero
1438 * job.c (construct_command_argv_internal): New argument FLAGS; all
1440 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1442 * job.h (construct_command_argv_internal): Update prototype.
1444 2007-07-13 Paul Smith <psmith@gnu.org>
1446 * file.c (expand_deps): Use variable_buffer as the start of the
1447 buffer, not the original pointer (in case it was reallocated).
1448 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1449 Fixes Savannah bug #20452.
1451 2007-07-04 Paul Smith <psmith@gnu.org>
1453 * (ALL FILES): Update to GPLv3.
1454 * (ALL FILES): Update copyright for 2007.
1456 * main.c (print_version): Move the host type info to the second line.
1458 2007-06-29 Thiemo Seufer <ths@mips.com>
1460 * maintMakefile: Update Translation Project location.
1462 2007-06-13 Paul Smith <psmith@gnu.org>
1464 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1465 "Expansion of a deferred"
1466 Fixes Savannah bug #20018.
1468 * expand.c (variable_expand_for_file): Preserve the value of
1469 reading_file rather than setting it to 0 at the end.
1470 Fixes Savannah bug #20033.
1472 2007-05-11 Paul Smith <psmith@gnu.org>
1474 * job.c (new_job): Add debug info to specify where make found the
1475 command script it is running to build a target.
1476 Fixes Savannah bug #18617.
1478 * default.c (default_suffixes,default_suffix_rules,default_variables):
1479 Add support for Objective C. Fixes Savannah bug #16389.
1480 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1482 * function.c (func_lastword): Initialize p.
1484 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1485 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1486 Dave Korn <dave.korn@artimi.com>
1488 2007-05-08 Paul Smith <psmith@gnu.org>
1490 Fix Savannah bug #19656:
1492 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1494 * make.h: Change all case-insensitive string compares to use
1495 strcasecmp() (from POSIX). If we don't have that but do have one
1496 of the others, define strcasecmp to be one of those instead. If
1497 we don't have any, declare a prototype for our own version.
1499 * misc.c (strcasecmp): Use this if we can't find any native
1500 case-insensitive string comparison function.
1501 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1502 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1504 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1505 strcasecmp() instead of stricmp().
1506 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1507 instead of strcmpi().
1508 * acinclude.m4: Remove the strcasecmp() check from here.
1510 2007-03-21 Paul Smith <psmith@gnu.org>
1512 * configure.in: Don't turn on case-insensitive file system support
1513 if --disable-... is given. Fixes Savannah bug #19348.
1515 2007-03-19 Paul Smith <psmith@gnu.org>
1517 * ALL: Use the strcache for all file name strings, or other
1518 strings which we will never free. The goal is to save memory by
1519 avoiding duplicate copies of strings. However, at the moment this
1520 doesn't save much memory in most situations: due to secondary
1521 expansion we actually save prerequisite lists twice (once before
1522 the secondary expansion, and then again after it's been parsed
1523 into individual file names in the dep list). We will resolve this
1524 in a future change, by doing the parsing up-front for targets
1525 where secondary expansion is not set.
1527 Moving things into the strcache also allows us to use const
1528 pointers in many more places.
1530 2007-01-03 Paul Smith <psmith@gnu.org>
1532 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1533 the function, not just the first. Fixes Savannah bug #18680.
1535 2006-11-18 Paul Smith <psmith@gnu.org>
1537 * strcache.c (strcache_add_len): Don't allocate a new buffer
1538 unless the string is not already nil-terminated. Technically this
1539 is a violation of the standard, since we may be passed an array
1540 that is not long enough to test one past. However, in make this
1541 is never true since we only use nil-terminated strings or
1542 sub-strings thereof.
1544 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1546 * main.c: New global cmd_prefix, defaults to '\t'.
1547 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1550 * dir.c: Constified.
1551 (dir_contents_file_exists_p): Check for an error return from
1552 readdir(), just in case.
1554 * commands.c: Constified.
1555 * default.c: Constified.
1556 * expand.c: Constified.
1557 * function.c: Partial constification.
1558 * variable.c: Partial constification.
1559 * vmsify.c: Constification. Hard to test this but I hope I didn't
1561 * vpath.c: Partial constification.
1562 * w32/pathstuff.c: Partial constification.
1564 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1566 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1567 backslashes and drive letters as absolute.
1569 2006-10-22 Paul Smith <psmith@gnu.org>
1571 * main.c (struct command_switch): Use const and void*.
1573 2006-10-21 Paul Smith <psmith@gnu.org>
1576 * arscan.c: Constified.

1648 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1649 inner-scope variables don't mask outer-scope variables.
1651 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1652 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:

1654 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1655 values from memory allocation functions: they return void* and so

1690 Version 3.81 released.
1692 * NEWS: Updated for 3.81.
1694 * README.cvs: Mention that vpath builds are not supported out of
1695 CVS. Fixes Savannah bug #16236.
1696 Remove update of make.texi from the list of things to do; we use
1699 2006-03-26 Paul D. Smith <psmith@gnu.org>
1701 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1702 support from automake, as described in the Texinfo manual.
1704 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1706 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1707 with lastslash, since the latter points to filename, not to

1710 Declare and define sh_chars_sh[].
1712 2006-03-23 Paul D. Smith <psmith@gnu.org>
1714 * configure.in: Look for build.sh.in in $srcdir so it will be
1715 built for remote configurations as well.
1717 * Makefile.am: Make sure to clean up build.sh during distclean.
1718 Fixes Savannah bug #16166.
1720 * misc.c (log_access): Takes a const char *.
1721 * function.c (fold_newlines): Takes an unsigned int *.
1722 Both fixes for Savannah bug #16170.
1724 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1726 * implicit.c (pattern_search): Call set_file_variables only
1727 if we have prerequisites that need second expansion. Fixes
1728 Savannah bug #16140.
1730 2006-03-19 Paul D. Smith <psmith@gnu.org>

1745 2006-03-17 Paul D. Smith <psmith@gnu.org>
1747 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1748 allow multiple concurrent runs.
1749 Patch from Joseph Myers <joseph@codesourcery.com>
1751 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1753 * dep.h (struct dep): Add the stem field.
1754 * misc.c (alloc_dep, free_dep): New functions.
1755 (copy_dep_chain): Copy stem.
1756 (free_dep_chain): Use free_dep.
1757 * read.c (record_files): Store stem in the dependency line.
1758 * file.c (expand_deps): Use stem stored in the dependency line. Use
1759 free_dep_chain instead of free_ns_chain.
1760 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1761 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1762 * main.c (main, handle_non_switch_argument): Ditto.
1763 * remake.c (check_dep): Ditto.

1766 2006-03-14 Paul D. Smith <psmith@gnu.org>

1771 (allocated_variable_append): Don't expand the final result.
1772 Fixes Savannah bug #15913.
1774 2006-03-09 Paul Smith <psmith@gnu.org>
1776 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1777 listed non-existent files as changed. Turns out there's a bug in
1778 the Linux kernel builds which means that this change causes
1779 everything to rebuild every time. We will re-introduce this fix
1780 in the next release, to give them time to fix their build system.
1781 Fixes Savannah bug #16002.
1782 Introduces Savannah bug #16051.
1784 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1791 locator function find_and_set_default_shell if SHELL came from the
1794 2006-02-20 Paul D. Smith <psmith@gnu.org>
1796 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1797 to be null; don't core in that case.
1799 2006-02-19 Paul D. Smith <psmith@gnu.org>
1801 * commands.c (set_file_variables): Realloc, not malloc, the static
1802 string values to avoid memory leaks.
1804 * expand.c (recursively_expand_for_file): Only set reading_file to
1805 an initialized value.
1807 * implicit.c (pattern_search): We need to make a copy of the stem
1808 if we get it from an intermediate dep, since those get freed.
1810 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1812 (enter_file) [VMS]: Ditto.
1813 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

1817 * job.c (construct_command_argv_internal): Fix last change.
1819 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1820 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1821 the calls to _beginthreadex.
1823 * expand.c (recursively_expand_for_file): Initialize `save' to
1824 prevent compiler warnings.
1826 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1828 * job.c (construct_command_argv_internal): Don't create a temporary
1829 script/batch file if we are under -n. Call _setmode to switch the
1830 script file stream to text mode.
1832 2006-02-17 Paul D. Smith <psmith@gnu.org>
1834 * variable.c (merge_variable_set_lists): Don't try to merge the
1835 global_setlist. Not only is this useless, but it can lead to
1836 circularities in the linked list, if global_setlist->next in one
1837 list gets set to point to another list which also ends in
1839 Fixes Savannah bug #15757.
1841 2006-02-15 Paul D. Smith <psmith@gnu.org>
1843 Fix for Savannah bug #106.
1845 * expand.c (expanding_var): Keep track of which variable we're
1846 expanding. If no variable is being expanded, it's the same as
1848 * make.h (expanding_var): Declare it.
1849 * expand.c (recursively_expand_for_file): Set expanding_var to the
1850 current variable we're expanding, unless there's no file info in
1851 it (could happen if it comes from the command line or a default
1852 variable). Restore it before we exit.
1853 * expand.c (variable_expand_string): Use the expanding_var file
1854 info instead of the reading_file info.
1855 * function.c (check_numeric): Ditto.
1857 (func_wordlist): Ditto.
1858 (func_error): Ditto.
1859 (expand_builtin_function): Ditto.
1860 (handle_function): Ditto.
1862 2006-02-14 Paul D. Smith <psmith@gnu.org>
1864 * read.c (eval): Even if the included filenames expands to the
1865 empty string we still need to free the allocated buffer.
1867 * implicit.c (pattern_search): If we allocated a variable set for
1868 an impossible file, free it.
1869 * variable.c (free_variable_set): New function.
1870 * variable.h: Declare it.
1872 * read.c (read_all_makefiles): Makefile names are kept in the
1873 strcache, so there's never any need to alloc/free them.
1876 * main.c (main): Add "archives" to the .FEATURES variable if
1877 archive support is enabled.
1878 * doc/make.texi (Special Variables): Document it.
1880 2006-02-13 Paul D. Smith <psmith@gnu.org>
1882 * implicit.c (pattern_search): Add checking for DOS pathnames to
1883 the pattern rule target LASTSLASH manipulation.

1888 * (ALL FILES): Updated copyright and license notices.
1890 2006-02-10 Paul D. Smith <psmith@gnu.org>
1892 A new internal capability: the string cache is a read-only cache
1893 of strings, with a hash table interface for fast lookup. Nothing
1894 in the cache will ever be freed, so there's no need for reference
1895 counting, etc. This is the beginning of a full solution for
1896 Savannah bug #15182, but for now we only store makefile names here.
1898 * strcache.c: New file. Implement a read-only string cache.
1899 * make.h: Add prototypes for new functions.
1900 * main.c (initialize_global_hash_tables): Initialize the string cache.
1901 (print_data_base): Print string cache stats.
1902 * read.c (eval_makefile): Use the string cache to store makefile
1903 names. Rewrite the string allocation to be sure we free everything.
1905 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1907 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1908 directory time stamp didn't change, except on FAT filesystems.
1909 Suggested by J. David Bryan <jdbryan@acm.org>.
1911 2006-02-09 Paul D. Smith <psmith@gnu.org>
1913 * function.c (func_or): Implement a short-circuiting OR function.
1914 (func_and): Implement a short-circuiting AND function.
1915 (function_table_init): Update the table with the new functions.
1916 * doc/make.texi (Conditional Functions): Changed the "if" section
1917 to one on general conditional functions. Added documentation for
1918 $(and ...) and $(or ...) functions.
1919 * NEWS: Note new $(and ...) and $(or ...) functions.

1924 * job.c (new_job): Cache dontcare flag.
1925 * job.c (reap_children): Use cached dontcare flag instead of the
1926 one in struct file. Fixes Savannah bug #15641.
1928 2006-02-06 Paul D. Smith <psmith@gnu.org>
1930 * vpath.c (selective_vpath_search): If the file we find has a
1931 timestamp from -o or -W, use that instead of the real time.
1932 * remake.c (f_mtime): If the mtime is a special token from -o or
1933 -W, don't overwrite it with the real mtime.
1934 Fixes Savannah bug #15341.
1936 Updates from Markus Mauhart <qwe123@chello.at>:
1938 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1939 (process_signal, process_last_err, process_exit_code): Manage
1940 invalid handle values.
1941 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1942 manage invalid handles; remove them.

1944 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.

1951 Fixes Savannah bug #15533.
1952 * filedef.h (struct file): Add a new LAST pointer.
1954 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1955 the comparison. For 64-bits systems the result of the subtraction
1956 might not fit into an int. Use comparison instead.
1957 Fixes Savannah bug #15534.
1959 * doc/make.texi: Update the chapter on writing commands to reflect
1960 the changes made in 3.81 for backslash/newline and SHELL handling.
1962 2006-02-01 Paul D. Smith <psmith@gnu.org>
1964 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
1965 variable st is not used when it's not initialized.
1966 Patch from Eli Zaretskii <eliz@gnu.org>.

1980 2006-01-21 Eli Zaretskii <eliz@gnu.org>
1982 * remake.c (update_goal_chain): Set g->changed instead of
1983 incrementing it, as it is only 8-bit wide, and could overflow if
1984 many commands got started in update_file.
1986 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
1988 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

2006 the shell is not sh.exe.
2008 * job.c (create_batch_file): Renamed from create_batch_filename;
2009 all callers changed. Don't close the temporary file; return its
2010 file descriptor instead. New arg FD allows to return the file
2012 (construct_command_argv_internal): Use _fdopen instead of fopen to
2013 open the batch file.
2015 2006-01-04 Paul D. Smith <psmith@gnu.org>

2044 * doc/make.texi (Execution): Add a footnote about changes in
2045 handling of backslash-newline sequences. Mention the differences
2046 on MS-DOS and MS-Windows.
2048 * NEWS: More details about building the MinGW port and a pointer
2049 to README.W32. Fix the section name that describes the new
2050 backward-incompatible processing of backslash-newline sequences.
2051 The special processing of SHELL set to "cmd" is only relevant to
2052 MS-Windows, not MS-DOS.
2054 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2056 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2057 to DWORD, to avoid compiler warnings.
2058 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2059 use %ld in format, to avoid compiler warnings.

2073 * read.c (record_target_var): Initialize variable's export field
2074 with v_default instead of leaving it "initialized" by whatever
2075 garbage happened to be on the heap.

2079 * make.1: Fix some display errors and document all existing options.
2080 Patch by Mike Frysinger <vapier@gentoo.org>.
2082 2005-12-11 Paul D. Smith <psmith@gnu.org>
2084 * implicit.c (pattern_search): If 2nd expansion is not set for
2085 this implicit rule, replace the pattern with the stem directly,
2086 and don't re-expand the variable list. Along with the other
2087 .SECONDEXPANSION changes below, fixes bug #13781.
2089 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2091 * implicit.c (pattern_search): Mark other files that this rule

2097 * remake.c (notice_finished_file): Propagate the change of
2098 modification time to all the double-colon entries only if
2099 it is the last one to be updated. Fixes bug #14334.
2101 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2103 * function.c (func_flavor): Implement the flavor function which
2104 returns the flavor of a variable.
2105 * doc/make.texi (Functions for Transforming Text): Document it.
2106 * NEWS: Add it to the list of new functions.
2108 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2110 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2112 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2113 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2115 2005-10-26 Paul Smith <psmith@gnu.org>
2117 * read.c (record_files): Don't set deps flags if there are no deps.
2118 * maintMakefile: We only need to build the templates when we are
2119 creating a distribution, so don't do it for "all".
2121 2005-10-24 Paul D. Smith <psmith@gnu.org>
2123 Make secondary expansion optional: its enabled by declaring the
2124 special target .SECONDEXPANSION.
2126 * NEWS: Update information on second expansion capabilities.
2127 * doc/make.texi (Secondary Expansion): Document the
2128 .SECONDEXPANSION special target and its behavior.
2129 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2130 prerequisite list was found in a static pattern rule.
2131 (free_dep_chain): Declare a prototype.
2132 * file.c (parse_prereqs): New function: break out some complexity
2134 (expand_deps): If we aren't doing second expansion, replace % with
2135 the stem for static pattern rules. Call the new function.
2136 * filedef.h (parse_prereqs): Declare a prototype.
2137 * implicit.c (pattern_search): Initialize the new staticpattern
2139 * main.c (second_expansion): Declare a global variable to remember
2140 if the special target has been seen. Initialize the new
2141 staticpattern field for prerequisites.
2142 * make.h: Extern for second_expansion.
2143 * misc.c (free_dep_chain): New function: frees a struct dep list.
2144 * read.c (read_all_makefiles): Initialize the staticpattern field.
2145 (eval_makefile): Ditto.
2146 (record_files): Check for the .SECONDEXPANSION target and set
2147 second_expansion global if it's found.
2148 Use the new free_dep_chain() instead of doing it by hand.
2149 Set the staticpattern field for prereqs of static pattern targets.
2151 2005-10-16 Paul D. Smith <psmith@gnu.org>
2153 * main.c (main): Set CURDIR to be a file variable instead of a
2154 default, so that values of CURDIR inherited from the environment
2155 won't override the make value.
2157 2005-09-26 Paul D. Smith <psmith@gnu.org>
2159 * job.c (construct_command_argv_internal): If the line is empty
2160 remember to free the temporary argv strings.
2163 2005-09-16 Paul D. Smith <psmith@gnu.org>
2165 * job.c (start_job_command): The noerror flag is a boolean (single
2166 bit); set it appropriately.
2167 Reported by Mark Eichin <eichin@metacarta.com>
2169 2005-08-29 Paul D. Smith <psmith@gnu.org>
2171 * function.c (func_error): On Windows, output from $(info ...)
2172 seems to come in the wrong order. Try to force it with fflush().
2174 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2176 * read.c (record_files): Move code that sets stem for static
2177 pattern rules out of the if (!two_colon) condition so it is
2178 also executed for two-colon rules. Fixes Savannah bug #13881.
2180 2005-08-08 Paul D. Smith <psmith@gnu.org>
2182 * make.h: Don't test that __STDC__ is non-0. Some compilers
2183 (Windows for example) set it to 0 to denote "ISO C + extensions".
2186 2005-08-07 Paul D. Smith <psmith@gnu.org>
2188 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2189 conditional (slightly different version of a fix from Eli).
2191 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2192 If make is running in parallel without -k and two jobs die in a
2193 row, but not too close to each other, then make will quit without
2194 waiting for the rest of the jobs to die.
2196 * main.c (die): Don't reset err before calling reap_children() the
2197 second time: we still want it to be in the error condition.
2198 * job.c (reap_children): Use a static variable, rather than err,
2199 to control whether or not the error message should be printed.
2201 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2203 * w32/subproc/sub_proc.c: Include signal.h.
2204 (process_pipe_io, process_file_io): Pass a pointer to a local
2205 DWORD variable to GetExitCodeProcess. If the exit code is
2206 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2208 * job.c [WINDOWS32]: Include windows.h.
2209 (main_thread) [WINDOWS32]: New global variable.
2210 (reap_children) [WINDOWS32]: Get the handle for the main thread
2211 and store it in main_thread.
2213 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2214 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2215 doing anything else. When we are done, close the main thread
2216 handle and exit with status 130.
2218 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2220 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2223 * main.c (find_and_set_default_shell): If found a DOSish shell,
2224 set sh_found and the value of default_shell, and report the
2225 findings in debug mode.
2227 * job.c (construct_command_argv_internal): Check unixy_shell, not
2228 no_default_sh_exe, to decide whether to use Unixy or DOSish
2231 * README.W32: Update with info about the MinGW build.
2233 * build_w32.bat: Support MinGW.
2235 * w32/subproc/build.bat: Likewise.
2237 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2238 printing DWORD args.
2240 * function.c (windows32_openpipe): Fix format strings for printing
2243 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2245 (start_job_command): Fix format string for printing the result of
2247 (start_job_command) [WINDOWS32]: Do not define.
2248 (exec_command): Fix format string for printing HANDLE args.
2250 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2251 to avoid compiler warnings.
2252 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2253 (Note: some of these fixes were submitted independently by J. Grant)
2255 2005-07-30 J. Grant <jg@jguk.org>
2257 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2258 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2259 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2261 2005-07-15 Paul Smith <psmith@gnu.org>
2263 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2264 we don't have a POSIX shell, then revert to the old
2265 backslash-newline behavior (where they are stripped).
2268 2005-07-08 Paul D. Smith <psmith@gnu.org>
2270 * config.h.W32.template: Reorder to match the standard config.h,
2271 for easier comparisons.
2272 From J. Grant <jg@jguk.org>
2274 * maintMakefile: Remove .dep_segment before overwriting it, in
2275 case it's not writable or noclobber is set.
2276 * expand.c (variable_expand_string): Cast result of pointer
2277 arithmetic to avoid a warning.
2278 * main.c (switches): Add full-fledged final initializer.
2280 2005-07-06 Paul D. Smith <psmith@gnu.org>
2282 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2283 * signame.c (strsignal): If we found _sys_siglist[] or
2284 __sys_siglist[] use those instead of sys_siglist[].
2285 From Albert Chin <china@thewrittenword.com>
2287 2005-07-04 Paul D. Smith <psmith@gnu.org>
2289 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2290 globfree(); set up to use the GNU versions.
2291 From Martin Zinser <zinser@zinser.no-ip.info>
2293 2005-07-03 Paul D. Smith <psmith@gnu.org>
2295 From J. Grant <jg@jguk.org>:
2297 * README.W32.template: Update the Windows and tested MSVC versions.
2298 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2299 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2300 * build_w32.bat: Ditto.
2301 * w32/subproc/build.bat: Ditto.
2303 2005-06-28 Paul D. Smith <psmith@gnu.org>
2305 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2306 declaration was checked but not present.
2308 2005-06-27 Paul D. Smith <psmith@gnu.org>
2310 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2311 to unsigned long. Fixes Savannah bug #13550.
2313 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2314 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2315 Fixes Savannah bug #13551.
2317 2005-06-26 Paul D. Smith <psmith@gnu.org>
2319 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2320 it if ANSI_STRING is not set.
2322 2005-06-25 Paul D. Smith <psmith@gnu.org>
2324 * read.c (eval): If no filenames are passed to any of the
2325 "include" variants, don't print an error.
2326 * doc/make.texi (Include): Document this.
2327 Fixes Savannah bug #1761.
2329 * job.c (construct_command_argv_internal): Sanitize handling of
2330 backslash/newline pairs according to POSIX: that is, keep the
2331 backslash-newline in the command script, but remove a following
2332 TAB character, if present. In the fast path, make sure that the
2333 behavior matches what the shell would do both inside and outside
2334 of quotes. In the slow path, quote the backslash and put a
2335 literal newline in the string.
2336 Fixes Savannah bug #1332.
2337 * doc/make.texi (Execution): Document the new behavior and give
2339 * NEWS: Make a note of the new behavior.
2341 * make.h [WINDOWS32]: #include <direct.h>.
2342 Fixes Savannah bug #13478.
2344 * remake.c (name_mtime): If the stat() of a file fails and the -L
2345 option was given and the file is a symlink, take the best mtime of
2346 the symlink we can get as the mtime of the file and don't fail.
2347 Fixes Savannah bug #13280.
2349 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2350 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2351 inside a variable reference. Make this function static as it's
2353 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2354 parsing an unexpanded line looking for semicolons.
2355 Fixes Savannah bug #1454.
2356 * misc.c (remove_comments): Move this to read.c and make it static
2357 as it's only used there. Call find_char_unquote() with new arg.
2358 * make.h: Remove prototypes for find_char_unquote() and
2359 remove_comments() since they're static now.
2361 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2362 its export flag and obtain its value. When we need to re-exec,
2363 increment the value and add it into the environment.
2364 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2365 * NEWS: Mention MAKE_RESTARTS.
2366 * main.c (always_make_set): New variable. Change the -B option to
2367 set this one instead.
2368 (main): When checking makefiles, only set always_make_flag if
2369 always_make_set is set AND the restarts flag is 0. When building
2370 normal targets, set it IFF always_make_set is set.
2371 (main): Avoid infinite recursion with -W, too: only set what-if
2372 files to NEW before we check makefiles if we've never restarted
2373 before. If we have restarted, set what-if files to NEW _after_ we
2375 Fixes Savannah bug #7566:
2377 2005-06-17 Paul D. Smith <psmith@gnu.org>
2379 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2380 in the prerequisites list.
2382 2005-06-12 Paul D. Smith <psmith@gnu.org>
2384 Fix Savannah bug # 1328.
2386 * configure.in: Check for atexit().
2387 * misc.c (close_stdout): Test stdout to see if writes to it have
2388 failed. If so, be sure to exit with a non-0 error code. Based on
2389 code found in gnulib.
2390 * make.h: Prototype.
2391 * main.c (main): Install close_stdout() with atexit().
2393 2005-06-10 Paul D. Smith <psmith@gnu.org>
2395 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2397 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2398 headers; make vmsWaitForChildren() static; extern vmsify().
2399 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2400 Don't create child_execute_job() here (it's in vmsjobs.c).
2401 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2403 2005-06-09 Paul D. Smith <psmith@gnu.org>
2405 * variable.c (push_new_variable_scope): File variables point
2406 directly to the global_setlist variable. So, inserting a new
2407 scope in front of that has no effect on those variables: they
2408 don't go through current_variable_set_list. If we're pushing a
2409 scope and the current scope is global, push it "the other way" so
2410 that the new setlist is in the global_setlist variable, and
2411 next points to a new setlist with the global variable set.
2412 (pop_variable_scope): Properly undo a push with the new
2414 Fixes Savannah bug #11913.
2416 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2418 * job.c (reap_children): Don't die of the command failed but
2419 the dontcare flag is set. Fixes Savannah bug #13216.
2421 * implicit.c (pattern_search): When creating a target from
2422 an implicit rule match, lookup pattern target and set precious
2423 flag in a newly created target. Fixes Savannah bug #13218.
2425 2005-05-13 Paul D. Smith <psmith@gnu.org>
2427 Implement "if... else if... endif" syntax.
2429 * read.c (eval): Push all checks for conditional words ("ifeq",
2430 "else", etc.) down into the conditional_line() function.
2431 (conditional_line): Rework to allow "else if..." clause. New
2432 return value -2 for lines which are not conditionals. The
2433 ignoring flag can now also be 2, which means "already parsed a
2434 true branch". If that value is seen no other branch of this
2435 conditional can be considered true. In the else parsing if there
2436 is extra text after the else, invoke conditional_line()
2437 recursively to see if it's another conditional. If not, it's an
2438 error. If so, raise the conditional value to this level instead
2439 of creating a new conditional nesting level. Special check for
2440 "else" and "endif", which aren't allowed on the "else" line.
2441 * doc/make.texi (Conditional Syntax): Document the new syntax.
2443 2005-05-09 Paul D. Smith <psmith@gnu.org>
2445 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2446 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2447 recurses to the w32 directory, even on non-Windows systems. Use
2448 the method suggested in the automake manual.
2449 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2450 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2452 2005-05-07 Paul D. Smith <psmith@gnu.org>
2454 * main.c (die): If we're dying with a fatal error (not that a
2455 command has failed), write back any leftover tokens before we go.
2457 * job.c (set_child_handler_action_flags): If there are jobs
2458 waiting for the load to go down, set an alarm to go off in 1
2459 second. This allows us to wake up from a potentially long-lasting
2460 read() and start a new job if the load has gone down. Turn it off
2462 (job_noop): Dummy signal handler function.
2463 (new_job): Invoke it with the new semantics.
2465 * docs/make.texi: Document secondary expansion. Various cleanups
2468 2005-05-03 Paul D. Smith <psmith@gnu.org>
2470 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2471 the targets which are to ultimately be made are called "goals";
2472 see the GNU make manual. Also, MAKECMDGOALS, etc.
2474 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2475 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2476 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2478 2005-05-02 Paul D. Smith <psmith@gnu.org>
2480 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2481 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2482 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2483 functions to vmsjobs.c. #include it into jobs.c.
2485 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2486 jobserver tokens. I found that this happens when an exported
2487 recursive variable contains a $(shell ...) function reference: in
2488 this situation we could "forget" to write back a token.
2490 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2491 we have. It's not reliable to depend on the number of children in
2492 our linked list so keep a separate count.
2493 (new_job): Check jobserver_tokens rather than children &&
2494 waiting_jobs. Increment jobserver_tokens when we get one.
2495 (free_child): If jobserver_tokens is 0, internal error. If it's
2496 >1, write a token back to the jobserver pipe (we don't write a
2497 token for the "free" job). Decrement jobserver_tokens.
2499 * main.c: Add variable master_job_slots.
2500 (main): Set it to hold the number of jobs requested if we're the
2501 master process, when using the jobserver.
2502 (die): Sanity checks: first test jobserver_tokens to make sure
2503 this process isn't holding any tokens we didn't write back.
2504 Second, if master_job_slots is set count the tokens left in the
2505 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2507 2005-04-24 Paul D. Smith <psmith@gnu.org>
2509 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2510 with -l# can lose jobserver tokens, because waiting jobs are not
2511 consulted properly when checking for the "free" token.
2513 * job.c (free_child): Count waiting_jobs as having tokens.
2514 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2515 handle jobs waiting for the load to drop.
2517 2005-04-23 Paul D. Smith <psmith@gnu.org>
2519 * main.c (main): Be careful to not core if a variable setting in
2520 the environment doesn't contain an '='. This is illegal but can
2521 happen in broken setups.
2522 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2524 2005-04-12 Paul D. Smith <psmith@gnu.org>
2526 The second expansion feature causes significant slowdown. Timing
2527 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2528 read the makefile before the feature, to 11+s to do the same
2529 operations after the feature. Additionally, memory usage
2530 increased drastically. To fix this I added some intelligence that
2531 avoids the overhead of the second expansion unless it's required.
2533 * dep.h: Add a new boolean field, need_2nd_expansion.
2535 * read.c (eval): When creating the struct dep for the target,
2536 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2537 (record_files): If there's a "%" in a static pattern rule, it gets
2538 converted to "$*" so set need_2nd_expansion to 1.
2540 * file.c (expand_deps): Rework to be more efficient. Only perform
2541 initialize_file_variables(), set_file_variables(), and
2542 variable_expand_for_file() if the need_2nd_expansion is set.
2544 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2545 (pattern_search): Ditto.
2546 * main.c (handle_non_switch_argument): Ditto.
2548 * read.c (read_all_makefiles): Ditto.
2549 (eval_makefile): Ditto.
2551 2005-04-07 Paul D. Smith <psmith@gnu.org>
2553 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2554 * variable.c (sync_Path_environment): Ditto.
2555 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2557 * main.c (main): Define the .FEATURES variable.
2558 * NEWS: Announce .FEATURES.
2559 * doc/make.texi (Special Variables): Document .FEATURES.
2561 * remake.c (check_dep): If a file is .PHONY, update it even if
2562 it's marked intermediate. Fixes Savannah bug #12331.
2564 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2566 * file.c (expand_deps): Factor out the second expansion and
2567 prerequisite line parsing logic from snap_deps().
2569 * file.c (snap_deps): Use expand_deps(). Expand and parse
2570 prerequisites of the .SUFFIXES special target first. Fixes
2571 Savannah bug #12320.
2573 2005-03-13 Paul D. Smith <psmith@gnu.org>
2575 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2578 2005-03-11 Paul D. Smith <psmith@gnu.org>
2580 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2581 available, not undefined (from Earnie Boyd).
2583 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2585 * implicit.c (pattern_search): Mark an intermediate target as
2586 precious if it happened to be a prerequisite of some (other)
2587 target. Fixes Savannah bug #12267.
2589 2005-03-09 Paul D. Smith <psmith@gnu.org>
2591 * read.c (eval_makefile): Add alloca(0).
2592 (eval_buffer): Ditto.
2594 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2596 * main.c (main): Use o_file instead of o_default when defining
2597 the .DEFAULT_TARGET special variable.
2598 * read.c (eval): Use define_variable_global() instead of
2599 define_variable() when setting new value for the .DEFAULT_TARGET
2600 special variable. Fixes Savannah bug #12266.
2602 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2604 * imlicit.c (pattern_search): Mark files for which an implicit
2605 rule has been found as targets. Fixes Savannah bug #12202.
2607 2005-03-04 Paul D. Smith <psmith@gnu.org>
2610 * doc/make.texi (Automatic Variables): Document $|.
2612 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2614 * read.c (record_files): Instead of substituting % with
2615 actual stem value in dependency list replace it with $*.
2616 This fixes stem triple expansion bug.
2618 * implicit.c (pattern_search): Copy stem to a separate
2619 buffer and make it a properly terminated string. Assign
2620 this buffer instead of STEM (which is not terminated) to
2621 f->stem. Instead of substituting % with actual stem value
2622 in dependency list replace it with $*. This fixes stem
2623 triple expansion bug.
2625 2005-03-01 Paul D. Smith <psmith@gnu.org>
2627 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2628 on Windows, as it takes a handle not a pid. Just exit.
2629 Fix from patch #3679, provided by Alessandro Vesely.
2631 * configure.in: Update check for sys_siglist[] from autoconf manual.
2632 * signame.c (strsignal): Update to use the new autoconf macro.
2634 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2636 * read.c (record_files): Add a check for the list of prerequisites
2637 of a static pattern rule being empty. Fixes Savannah bug #12180.
2639 2005-02-28 Paul D. Smith <psmith@gnu.org>
2641 * doc/make.texi (Text Functions): Update docs to allow the end
2642 ordinal for $(wordlist ...) to be 0.
2643 * function.c (func_wordlist): Fail if the start ordinal for
2644 $(wordlist ...) is <1. Matches documentation.
2645 Resolves Savannah support request #103195.
2647 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2648 previously we were stopping when !-q, exactly the opposite. This
2649 has been wrong since version 1.34, in 1994!
2650 (update_file): If we got an error don't break out to run more
2651 double-colon rules: just return immediately.
2652 Fixes Savannah bug #7144.
2654 2005-02-27 Paul D. Smith <psmith@gnu.org>
2656 * misc.c (end_of_token): Make argument const.
2657 * make.h: Update prototype.
2659 * function.c (abspath, func_realpath, func_abspath): Use
2660 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2661 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2662 * read.c (record_files): Ditto.
2663 * variable.c (do_variable_definition): Ditto.
2665 * function.c (func_error): Create a new function $(info ...) that
2666 simply prints the message to stdout with no extras.
2667 (function_table_init): Add new function to the table.
2668 * NEWS: Add $(info ...) reference.
2669 * doc/make.texi (Make Control Functions): Document it.
2671 New feature: if the system supports symbolic links, and the user
2672 provides the -L/--check-symlink-time flag, then use the latest
2673 mtime between the symlink(s) and the target file.
2675 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2676 readlink(). If both are available, define MAKE_SYMLINKS.
2677 * main.c: New variable: check_symlink_flag.
2678 (usage): Add a line for -L/--check-symlink-times to the help string.
2679 (switches): Add -L/--check-symlink-times command line argument.
2680 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2681 print a warning and disable it again.
2682 * make.h: Declare check_symlink_flag.
2683 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2684 if the file is a symlink then check each link in the chain and
2685 choose the NEWEST mtime we find as the mtime for the file. The
2686 newest mtime might be the file itself!
2687 * NEWS: Add information about this new feature.
2688 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2690 Avoid core dumps described in Savannah bug # 12124:
2692 * file.c: New variable snapped_deps remember whether we've run
2694 (snap_deps): Set it.
2695 * filedef.h: Extern it.
2696 * read.c (record_files): Check snapped_deps; if it's set then
2697 we're trying to eval a new target/prerequisite relationship from
2698 within a command script, which we don't support. Fatal.
2700 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2702 Implementation of the .DEFAULT_TARGET special variable.
2704 * read.c (eval): If necessary, update default_target_name when
2706 * read.c (record_files): Update default_target_file if
2707 default_target_name has changed.
2708 * main.c (default_target_name): Define.
2709 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2710 default_target_name is set use default_target_file as a root
2712 * filedef.h (default_target_name): Declare.
2713 * dep.h (free_dep_chain):
2714 * misc.c (free_dep_chain): Change to operate on struct nameseq
2715 and change name to free_ns_chain.
2716 * file.c (snap_deps): Update to use free_ns_chain.
2718 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2720 Implementation of the second expansion in explicit rules,
2721 static pattern rules and implicit rules.
2723 * read.c (eval): Refrain from chopping up rule's dependencies.
2724 Store them in a struct dep as a single dependency line. Remove
2725 the code that implements SySV-style automatic variables.
2727 * read.c (record_files): Adjust the code that handles static
2728 pattern rules to expand all percents instead of only the first
2729 one. Reverse the order in which dependencies are stored so that
2730 when the second expansion reverses them again they appear in
2731 the makefile order (with some exceptions, see comments in
2732 the code). Remove the code that implements SySV-style automatic
2735 * file.c (snap_deps): Implement the second expansion and chopping
2736 of dependency lines for explicit rules.
2738 * implicit.c (struct idep): Define an auxiliary data type to hold
2739 implicit rule's dependencies after stem substitution and
2742 * implicit.c (free_idep_chain): Implement.
2744 * implicit.c (get_next_word): Implement helper function for
2745 parsing implicit rule's dependency lines into words taking
2746 into account variable expansion requests. Used in the stem
2749 * implicit.c (pattern_search): Implement the second expansion
2750 for implicit rules. Also fixes bug #12091.
2752 * commands.h (set_file_variables): Declare.
2753 * commands.c (set_file_variables): Remove static specifier.
2755 * dep.h (free_dep_chain): Declare.
2756 * misc.c (free_dep_chain): Implement.
2758 * variable.h (variable_expand_for_file): Declare.
2759 * expand.c (variable_expand_for_file): Remove static specifier.
2761 * make.h (strip_whitespace): Declare.
2762 * function.c (strip_whitespace): Remove static specifier.
2764 2005-02-26 Paul D. Smith <psmith@gnu.org>
2766 * main.c (main): Check for ferror() when reading makefiles from stdin.
2767 Apparently some shells in Windows don't close pipes properly and
2770 2005-02-24 Jonathan Grant <jg@jguk.org>
2772 * configure.in: Add MinGW configuration options, and extra w32 code
2774 * Makefile.am: Add MinGW configuration options, and extra w32 code
2776 * main.c: Determine correct program string (after last \ without .exe).
2777 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2779 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2780 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2781 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2782 environment support.
2784 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2786 * function.c (func_shell): When initializing error_prefix, check
2787 that reading file name is not null. This fixes long-standing
2788 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2790 2005-02-09 Paul D. Smith <psmith@gnu.org>
2792 * maintMakefile: Update the CVS download URL to simplify them.
2793 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2794 downloading the .texi files from Savannah now.
2796 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2798 * main.c (handle_non_switch_argument): Only add variables to
2799 command_variables if they're not already there: duplicate settings
2800 waste space and can be confusing to read.
2802 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2803 this header is never included by non-WINDOWS32 code, and it
2804 requires <config.h> to define which isn't always included first.
2806 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2807 testing MINGW32 versions.
2809 * main.c (log_working_directory): flush stdout to be sure the WD
2810 change is printed before any stderr messages show up.
2812 2005-02-01 Paul D. Smith <psmith@gnu.org>
2814 * maintMakefile (po_repo): Update the GNU translation site URL.
2816 2004-12-01 Paul D. Smith <psmith@gnu.org>
2818 * main.c (main): Change char* env_shell to struct variable shell_var.
2819 * variable.c (target_environment): Use new shell_var.
2821 2004-11-30 Paul D. Smith <psmith@gnu.org>
2823 * configure.in: The old way we avoided creating build.sh from
2824 build.sh.in before build.sh.in exists doesn't work anymore; we
2825 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2826 the help!). This also keeps automake from complaining.
2827 * Makefile.am (README): Add a dummy target so automake won't
2828 complain that this file doesn't exist when we checkout from CVS.
2829 * maintMakefile (.dep_segment): Rewrite this rule since newer
2830 versions of automake don't provide DEP_FILES.
2832 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2834 Implementation of `realpath' and `abspath' built-in functions.
2836 * configure.in: Check for realpath.
2837 * function.c (abspath): Return an absolute file name that does
2838 not contain any `.' or `..' components, nor repeated `/'.
2839 * function.c (func_abspath): For each name call abspath.
2840 * function.c (func_realpath): For each name call realpath
2841 from libc or delegate to abspath if realpath is not available.
2842 * doc/make.texi (Functions for File Names): Document new functions.
2843 * doc/make.texi (Quick Reference): Ditto.
2845 2004-11-28 Paul D. Smith <psmith@gnu.org>
2847 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2848 arguments. Fixes bug #10252.
2850 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2852 * main.c (main): Set SHELL to v_noexport by default. Remember the
2853 original environment setting of SHELL in the env_shell variable.
2854 * main.h: Export new env_shell variable.
2855 * variable.c (target_environment): If we find a v_noexport
2856 variable for SHELL, add a SHELL variable with the env_shell value.
2857 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2858 * doc/make.texi (Variables/Recursion): Ditto.
2860 2004-11-28 Paul D. Smith <psmith@gnu.org>
2862 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2863 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2864 Patch by Alessandro Vesely.
2866 2004-11-12 Paul D. Smith <psmith@gnu.org>
2868 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2869 the command line if it's inside a string.
2870 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2872 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2874 * function.c (func_lastword): New function: return last word
2875 from the list of words.
2876 * doc/make.texi: Document $(lastword ). Fix broken links in
2877 Quick Reference section.
2879 2004-10-06 Paul D. Smith <psmith@gnu.org>
2881 Apply patch from Alessandro Vesely, provided with bug # 9748.
2882 Fix use of tmpnam() to work with Borland C.
2884 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2885 construction of a temporary filename, and call new function
2886 create_batch_filename().
2887 (create_batch_filename) [WINDOWS32]: New function to create a
2890 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2892 * read.c (record_target_var): Expand simple pattern-specific
2894 * variable.c (initialize_file_variables): Do not expand simple
2895 pattern-specific variable.
2897 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2899 * remake.c (update_file_1): When rebuilding makefiles inherit
2900 dontcare flag from a target that triggered update.
2902 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2904 * variable.c (initialize_file_variables): Mark pattern-specific
2905 variable as a per-target and copy export status.
2907 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2909 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2911 * implicit.c (pattern_search): When considering an implicit rule's
2912 prerequisite check that it is actually a target rather then
2913 just an entry in the file hashtable.
2915 2004-09-21 Paul D. Smith <psmith@gnu.org>
2917 * read.c (readstring): Fix some logic errors in backslash handling.
2918 (eval): Remove some unnecessary processing in buffer handling.
2919 (record_target_var): Assert that parse_variable_definition() succeeded.
2920 Reported by: Markus Mauhart <qwe123@chello.at>.
2922 * misc.c: Removed the sindex() function. All instances of this
2923 function were trivially replaceable by the standard strstr()
2924 function, and that function will always have better (or certainly
2925 no worse) performance than the very simple-minded algorithm
2926 sindex() used. This can matter with complex makefiles.
2927 * make.h: Remove the prototype for sindex().
2928 * function.c (subst_expand): Convert sindex() call to strstr().
2929 This means we no longer need to track the TLEN value so remove that.
2930 (func_findstring): Convert sindex() to strstr().
2931 * commands.c (chop_commands): Convert sindex() calls to strstr().
2932 Suggested by: Markus Mauhart <qwe123@chello.at>.
2934 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2935 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2936 If SHELL is set to CMD.EXE then assume it's batch-mode and
2937 non-unixy. I wrote the code differently from the patch, though,
2938 to make it safer. This also resolves bug #9174.
2940 2004-09-20 Paul D. Smith <psmith@gnu.org>
2942 * expand.c (variable_expand_string): Modify to invoke
2943 patsubst_expand() instead of subst_expand(); the latter didn't
2944 handle suffix patterns correctly.
2945 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2946 was used only from variable_expand_string() and is no longer used
2948 (func_subst): Ditto, on call to subst_expand().
2949 (patsubst_expand): Require the percent pointers to point to the
2950 character after the %, not to the % itself.
2951 * read.c (record_files): New call criteria for patsubst_expand().
2952 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2953 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2955 2004-09-19 Paul D. Smith <psmith@gnu.org>
2957 * function.c (subst_expand): Fix a check in by_word: look for a
2958 previous blank if we're beyond the beginning of the string, not
2959 the beginning of the word.
2960 Bugs reported by Markus Mauhart <qwe123@chello.at>.
2962 2004-05-16 Paul D. Smith <psmith@gnu.org>
2964 * remake.c (update_goal_chain): Change the argument specifying
2965 whether we're rebuilding makefiles to be a global variable,
2966 REBUILDING_MAKEFILES.
2967 (complain): Extract the code that complains about no rules to make
2968 a target into a separate function.
2969 (update_file_1): If we tried to rebuild a file during the makefile
2970 rebuild phase and it was dontcare, then no message was printed.
2971 If we then try to build the same file during the normal build,
2972 print a message this time.
2973 (remake_file): Don't complain about un-remake-able files when
2974 we're rebuilding makefiles.
2976 2004-05-11 Paul D. Smith <psmith@gnu.org>
2978 * job.c (construct_command_argv_internal): OS/2 patches from
2979 Andreas Buening <andreas.buening@nexgo.de>.
2981 2004-05-10 Paul D. Smith <psmith@gnu.org>
2983 * remake.c (update_file): Don't walk the double-colon chain unless
2984 this is a double-colon rule. Fix suggested by Boris Kolpackov
2985 <boris@kolpackov.net>.
2987 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
2988 * readme.vms: New section describing OpenVMS support and issues.
2989 * default.c (default_variables): Add support for IA64.
2990 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
2991 without some privilege aborts make with the error
2992 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
2993 pressing Ctrl+Y and the input device is no terminal. The change
2994 catches this error and just continues.
2996 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2998 2004-04-25 Paul D. Smith <psmith@gnu.org>
3000 * commands.c (set_file_variables): Set $< properly in the face of
3001 order-only prerequisites.
3002 Patch from Boris Kolpackov <boris@kolpackov.net>
3004 2004-04-21 Bob Byrnes <byrnes@curl.com>
3006 * main.c (main): Notice failures to remake makefiles.
3008 2004-03-28 Paul D. Smith <psmith@gnu.org>
3010 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3012 * job.c: No default shell for RISC OS.
3013 (load_too_high): Hard-code the return to 1.
3014 (construct_command_argv_internal): No sh_chars or sh_cmds.
3015 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3017 2004-03-20 Paul D. Smith <psmith@gnu.org>
3019 * variable.c (do_variable_definition): Don't append from the
3020 global set if a previous non-appending target-specific variable
3021 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3024 * expand.c (reference_variable): Don't give up on variables with
3025 no value that have the target-specific append flag set: they might
3026 have a value after all. Reported by Oliver Schmidt
3027 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3028 <nikulin@dx1cmd.inp.nsk.su>.
3030 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3031 refer to absolute pathnames in directories that don't exist: some
3032 portion of the makefile could create those directories before we
3033 match the pattern. Fixes bugs #775 and #108.
3035 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3037 * main.c (main): Free makefile_mtimes if we have any.
3038 * README.W32.template: Update documentation for the current status
3039 of the MS-Windows port.
3040 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3041 environment variable is sometimes already defined which causes the
3043 * main.c (debug_signal_handler): Only define this function if
3044 SIGUSR1 is available.
3046 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3048 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3049 * README.OS2.template: Documentation updates.
3050 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3051 link line for safety.
3052 * maintMakefile (build.sh.in): Remove an extraneous ")".
3053 * job.c (child_execute_job): Close saved FDs.
3054 * job.c (exec_command) [OS/2]: exec_command(): If the command
3055 can't be exec'ed and if the shell is not Unix-sh, then try again
3056 with argv = { "cmd", "/c", ... }. Normally, this code is never
3057 reached for the cmd shell unless the command really doesn't exist.
3058 (construct_command_argv_internal) [OS/2]: The code for cmd
3059 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3060 The CMD builtin commands are case insensitive so use strcasecmp().
3062 2004-03-19 Paul D. Smith <psmith@gnu.org>
3064 * read.c (do_define): Re-order line counter increment so the count
3065 is accurate (we were losing one line per define). Reported by
3066 Dave Yost <Dave@Yost.com>.
3068 2004-03-06 Paul D. Smith <psmith@gnu.org>
3070 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3072 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3073 * misc.c (message,error,fatal): Ditto.
3074 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3075 * config.h.W32.template: Ditto.
3076 * config.h-vms.template: Ditto.
3077 * config.ami.template: Ditto.
3079 2004-03-04 Paul D. Smith <psmith@gnu.org>
3081 * README.template: Add a note about broken /bin/sh on SunOS
3082 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3084 * misc.c (message, error, fatal): Don't use "..." if we're using
3085 varargs. ansi2knr should handle this but it doesn't work: it
3086 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3087 done. On many systems (SunOS for example) va_dcl is a #define.
3088 So, force the use of the non-"..." version on pre-ANSI compilers.
3090 * maintMakefile (sign-dist): Create some rules to help automate
3091 the new GNU ftp upload method.
3093 2004-02-24 Paul D. Smith <psmith@gnu.org>
3095 * config.h.W32.template: Add HAVE_STDARG_H
3096 * config.h-vms.template: Ditto.
3097 * config.ami.template: Ditto.
3099 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3101 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3102 * build_w32.bat: Remove extra "+".
3104 2004-02-23 Paul D. Smith <psmith@gnu.org>
3106 * make.h: Create an UNUSED macro to mark unused parameters.
3107 * (many): Clean up warnings by applying UNUSED, fixing
3108 signed/unsigned incompatibilities, etc.
3110 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3112 * filedef.h: Name the command_state enumeration.
3113 * file.c (set_command_state): Use the enumeration in the function
3116 * configure.in: Explicitly set SET_MAKE to empty, to disable
3117 MAKE=make even when no make already exists. Fix bug #3823.
3119 2004-02-22 Paul D. Smith <psmith@gnu.org>
3121 * maintMakefile: Perl script to clean up all non-CVS files. Use
3122 it on all the subdirectories for the cvs-clean target.
3124 * main.c (decode_switches): Require non-empty strings for all our
3125 string command-line options. Fixes Debian bug # 164165.
3127 * configure.in: Check for stdarg.h and varargs.h.
3128 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3129 for printing messages.
3130 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3135 A number of patches for OS/2 support from Andreas Buening
3136 <andreas.buening@nexgo.de>:
3138 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3139 disable the SIGCHLD handler.
3140 (reap_children) [OS/2]: Remove special handling of job_rfd.
3141 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3142 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3143 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3144 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3145 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3148 2004-02-21 Paul D. Smith <psmith@gnu.org>
3150 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3151 <mail@kristov.de> reports that if process_begin() fails we don't
3152 handle the error condition correctly in all cases.
3153 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3154 to have a newline on the message.
3156 * job.c (construct_command_argv_internal): Add "test" to UNIX
3157 sh_cmds[]. Fixes Savannah bug # 7606.
3159 2004-02-04 Paul D. Smith <psmith@gnu.org>
3161 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3162 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3163 Hartmut Becker <Hartmut.Becker@hp.com>.
3165 2004-01-21 Paul D. Smith <psmith@gnu.org>
3167 * job.c (load_too_high): Implement an algorithm to control the
3168 "thundering herd" problem when using -l to control job creation
3169 via the load average. The system only recomputes the load once a
3170 second but we can start many jobs in a second. To solve this we
3171 keep track of the number of jobs started in the last second and
3172 apply a weight to try to guess what a correct load would be.
3173 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3174 Also fixes bug #4693.
3175 (reap_children): Decrease the job count for this second.
3176 (start_job_command): Increase the job count for this second.
3178 * read.c (conditional_line): Expand the text after ifn?def before
3179 checking to see if it's a single word. Fixes bug #7257.
3181 2004-01-09 Paul D. Smith <psmith@gnu.org>
3183 * file.c (print_file): Recurse to print all targets in
3184 double-colon rules. Fixes bug #4518, reported (with patch) by
3185 Andrew Chatham <chatham@google.com>.
3187 2004-01-07 Paul D. Smith <psmith@gnu.org>
3189 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3190 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3191 AC_FUNC_SETVBUF_REVERSED.
3193 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3194 (MAKE Variable): Fix Savannah bug #4898.
3196 * job.c (construct_command_argv_internal): Add "!" to the list of
3197 shell escape chars. POSIX sh allows it to appear before a
3198 command, to negate the exit code. Fixes bug #6404.
3200 * implicit.c (pattern_search): When matching an implicit rule,
3201 remember which dependencies have the ignore_mtime flag set.
3202 Original fix provided in Savannah patch #2349, by Benoit
3203 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3205 2003-11-22 Paul D. Smith <psmith@gnu.org>
3207 * README.W32.template (Outputs): Clarification on -j with
3208 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3211 2003-11-02 Paul D. Smith <psmith@gnu.org>
3213 * function.c (func_if): Strip all the trailing whitespace from the
3214 condition, then don't expand it. Fixed bug # 5798.
3216 * expand.c (recursively_expand_for_file): If we're expanding a
3217 variable with no file context, then use the variable's context.
3220 2003-10-21 Paul D. Smith <psmith@gnu.org>
3222 * main.c (log_working_directory): Add newlines to printf()s.
3224 * README.cvs: Add a note to ignore warnings during autoreconf.
3226 * maintMakefile (po_repo): Set a new URL for PO file updates.
3227 (get-config/config.guess get-config/config.sub): Get these files
3228 from the Savannah config project instead of ftp.gnu.org.
3230 2003-10-05 Paul Eggert <eggert@twinsun.com>
3232 * main.c (main): Avoid potential subscript error if environ has
3235 2003-08-22 Paul D. Smith <psmith@gnu.org>
3237 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3238 systems which don't yet implement the C89 standard :-/.
3240 2003-07-18 Paul D. Smith <psmith@gnu.org>
3242 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3243 [WINDOWS32]: Initialize hash.
3245 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3247 * dir.c (read_dirstream): Provide a workaround for broken versions of
3248 the MinGW dirent structure.
3250 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3252 * w32/include/dirent.h: Add __MINGW32__ filter.
3254 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3256 * make.h: Add global declaration of *make_host.
3257 * main.c (print_usage): Remove local declaration of *make_host.
3258 (print_version): Display "This program built for ..." after Copyright
3261 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3263 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3264 execution of "makeinfo --html make.texi".
3266 2003-04-30 Paul D. Smith <psmith@gnu.org>
3268 * build.template: Make some changes to maybe allow this script to
3269 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3271 * README.OS2.template: New file for OS/2 support. Original
3272 contributed by Andreas Buening.
3273 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3276 2003-04-19 Paul D. Smith <psmith@gnu.org>
3278 Fix bug #1405: allow a target to match multiple pattern-specific
3281 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3282 variable.c, where they've always belonged.
3283 * rule.h: Move the prototypes and struct pattern_var as well.
3284 * variable.c (initialize_file_variables): Invoke
3285 lookup_pattern_var() in a loop, until no more matches are found.
3286 If a match is found, create a new variable set for the target's
3287 pattern variables. Then merge the contents of each matching
3288 pattern variable set into the target's pattern variable set.
3289 (lookup_pattern_var): Change this function to be usable
3290 in a loop. It takes a starting position: if NULL, start at the
3291 beginning; if non-NULL, start with the pattern variable after that
3292 position, and return the next matching pattern.
3293 (create_pattern_var): Create a unique instance of
3294 pattern-specific variables for every definition in the makefile.
3295 Don't combine the same pattern together. This allows us to
3296 process the variable handling properly even when the same pattern
3297 is used multiple times.
3298 (parse_variable_definition): New function: break out the parsing
3299 of a variable definition line from try_variable_definition.
3300 (try_variable_definition): Call parse_variable_definition to
3302 (print_variable_data_base): Print out pattern-specific variables.
3303 * variable.h (struct variable): Remember when a variable is
3304 conditional. Also remember its flavor.
3305 (struct pattern_var): Instead of keeping a variable set, we just
3306 keep a single variable for each pattern.
3307 * read.c (record_target_var): Each pattern variable contains only a
3308 single variable, not a set, so create it properly.
3309 * doc/make.texi (Pattern-specific): Document the new behavior.
3311 2003-04-17 Paul D. Smith <psmith@gnu.org>
3313 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3314 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3315 file/directory naming rules for VMS so I can't tell whether this
3318 2003-04-09 Paul D. Smith <psmith@gnu.org>
3320 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3321 DOS-style pathnames: backslash separators and drive specifiers.
3323 2003-03-28 Paul D. Smith <psmith@gnu.org>
3325 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3326 the intermediate flag on all targets. Fixes bug #2515.
3328 2003-03-24 Paul D. Smith <psmith@gnu.org>
3330 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3331 Upgrade to autoconf 2.57 and automake 1.7.3.
3333 * job.c: More OS/2 changes from Andreas Buening.
3335 * file.c (print_file): Fix variable initialization.
3338 * remake.c (notice_finished_file):
3340 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3341 some calls (like readdir()) return NULL in valid situations
3342 without resetting errno. Fixes bug #2846.
3344 2003-02-25 Paul D. Smith <psmith@gnu.org>
3346 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3348 * job.c (_is_unixy_shell) [OS/2]: New function.
3349 Set default shell to /bin/sh.
3350 (reap_children): Close the job_rfd pipe here since we don't use a
3352 (set_child_handler_action_flags): define this to empty on OS/2.
3353 (start_job_command): Close the jobserver pipe and use
3354 child_execute_job() instead of fork/exec.
3355 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3356 rather than exec'ing, then reconfigure stdin/stdout.
3357 (exec_command): Rewrite to use spawn instead of exec. Return the
3360 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3361 in DOS. Handle the TEMP environment variable as in DOS. Don't
3362 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3363 use -j in DOS mode. Use child_execute_job() instead of
3366 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3369 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3370 prototypes that return values.
3372 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3374 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3375 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3377 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3380 2003-02-24 Paul D. Smith <psmith@gnu.org>
3382 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3383 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3384 (child_execute_job) [VMS]: Handle error status properly.
3385 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3387 * function.c (func_shell): Use EINTRLOOP() while reading from the
3388 subshell pipe (Fixes bug #2502).
3389 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3391 * main.c (main): Ditto.
3393 2003-01-30 Paul D. Smith <psmith@gnu.org>
3395 * read.c (eval): eval() was not fully reentrant, because the
3396 collapsed buffer was static. Change it to be an automatic
3397 variable so that eval() can be invoked recursively.
3399 (eval): Apply patch # 1022: fix memory reference error on long
3400 target-specific variable lines.
3401 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3403 * function.c (check_numeric): Combine the is_numeric() function
3404 into this function, since it's only called from one place.
3405 Constify this function. Have it print the incorrect string in the
3406 error message. Fixes bug #2407.
3407 (strip_whitespace): Constify.
3408 (func_if): Constify.
3409 * expand.c (expand_argument): Constify.
3411 2003-01-29 Paul D. Smith <psmith@gnu.org>
3413 Fix bug # 2169, also reported by other people on various systems.
3415 * make.h: Some systems, such as Solaris and PTX, do not fully
3416 implement POSIX-compliant SA_RESTART functionality; important
3417 system calls like stat() and readdir() can still fail with EINTR
3418 even if SA_RESTART has been set on the signal handler. So,
3419 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3420 EINTR for system calls which return -1 or 0 (NULL), respectively,
3422 Also, remove the old atomic_stat()/atomic_readdir() and
3423 HAVE_BROKEN_RESTART handling.
3425 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3427 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3428 * remake.c (touch_file): Ditto.
3430 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3431 * read.c (construct_include_path): Ditto.
3432 * remake.c (name_mtime): Ditto.
3433 * vpath.c (selective_vpath_search): Ditto.
3434 * dir.c (find_directory): Ditto.
3435 (local_stat): Ditto.
3436 (find_directory): Use ENULLLOOP() to wrap opendir().
3437 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3439 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3440 atomic_readdir() handling.
3442 2003-01-22 Paul D. Smith <psmith@gnu.org>
3444 * function.c (func_call): Fix Bug #1744. If we're inside a
3445 recursive invocation of $(call ...), mask any of the outer
3446 invocation's arguments that aren't used by this one, so that this
3447 invocation doesn't "inherit" them accidentally.
3449 2002-12-05 Paul D. Smith <psmith@gnu.org>
3451 * function.c (subst_expand): Valery Khamenia reported a
3452 pathological performance hit when doing substitutions on very
3453 large values with lots of words: turns out we were invoking
3454 strlen() a ridiculous number of times. Instead of having each
3455 call to sindex() call strlen() again, keep track of how much of
3456 the text we've seen and pass the length to sindex().
3458 2002-11-19 Paul D. Smith <psmith@gnu.org>
3460 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3463 2002-11-16 Paul D. Smith <psmith@gnu.org>
3465 * NMakefile.template (OBJS): Add hash.c object file.
3466 * SMakefile.template (srcs): Ditto.
3467 * Makefile.ami (objs): Ditto.
3468 * build_w32.bat: Ditto.
3470 * Makefile.DOS.template: Remove extra dependencies.
3472 2002-10-25 Paul D. Smith <psmith@gnu.org>
3474 * expand.c (install_variable_buffer): New function. Install a new
3475 variable_buffer context and return the previous one.
3476 (restore_variable_buffer): New function. Free the current
3477 variable_buffer context and put a previously saved one back.
3478 * variable.h: Prototypes for {install,restore}_variable_buffer.
3479 * function.c (func_eval): Push a new variable_buffer context
3480 before we eval, then restore the old one when we're done.
3483 * read.c (install_conditionals): New function. Install a new
3484 conditional context and return the previous one.
3485 (restore_conditionals): New function. Free the current
3486 conditional context and put a previously saved one back.
3487 (eval): Use the {install,restore}_conditionals for "include"
3489 (eval_buffer): Use {install,restore}_conditionals to preserve the
3490 present conditional state before we evaluate the buffer.
3493 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3495 (Recursion): Add a variable index entry for CURDIR.
3497 * README.cvs: Update to appropriate versions.
3498 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3499 don't need to copy loadavg.c: automake is smart enough to create
3500 it for me. Still have a bug in automake related to ansi2knr tho.
3502 2002-10-14 Paul D. Smith <psmith@gnu.org>
3504 * remake.c (notice_finished_file): Only touch targets if they have
3505 at least one command (as per POSIX). Resolve Bug #1418.
3507 * *.c: Convert to using ANSI C-style function definitions.
3508 * Makefile.am: Enable the ansi2knr feature of automake.
3509 * configure.in: ditto.
3511 2002-10-13 Paul D. Smith <psmith@gnu.org>
3513 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3514 for automatic variable values like $^, etc. In the case of very
3515 large lists of prerequisites this causes problems. Instead reuse
3516 a static buffer (resizeable) for each variable.
3518 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3519 target-specific variable definitions. Check for it and set an
3521 (record_target_var): Set the export field to v_export if the
3522 "exported" flag is set.
3523 * doc/make.texi (Target-specific): Document the ability to use
3526 * doc/make.texi: Change the name of the section on automatic
3527 variables from "Automatic" to "Automatic Variables". Added text
3528 clarifying the scope of automatic variables.
3530 2002-10-04 Paul D. Smith <psmith@gnu.org>
3532 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3534 (record_files): Ditto.
3536 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3537 the search for the '=' to only within the enclosing parens.
3539 2002-10-03 Paul D. Smith <psmith@gnu.org>
3541 Version 3.80 released.
3543 * dir.c: Change hash functions to use K&R function definition style.
3544 * function.c: Ditto.
3546 * variable.c: Ditto.
3548 Update to automake 1.7.
3550 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3551 (pdf): Remove this target as automake now provides one.
3553 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3555 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3557 * makefile.com: Updates for GNU make 3.80.
3558 * makefile.vms: Ditto.
3560 2002-09-23 Paul D. Smith <psmith@gnu.org>
3562 * read.c (enum make_word_type): Remove w_comment.
3563 (get_next_mword): Don't treat comment characters as special; where
3564 this function is used we will never see a comment (it's stripped
3565 before we get here) and treating comments specially means that
3566 targets like "foo\#bar" aren't handled properly.
3568 2002-09-18 Paul D. Smith <psmith@gnu.org>
3570 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3572 * read.c (eval): Expansion of arguments to export/unexport was
3573 ignoring all arguments after the first one. Change the algorithm
3574 to expand the whole line once, then parse the results.
3576 2002-09-17 Paul D. Smith <psmith@gnu.org>
3578 Fix Bug #940 (plus another bug I found while looking at this):
3580 * read.c (record_target_var): enter_file() will add a new entry if
3581 it's a double-colon target: we don't want to do that in this
3582 situation. Invoke lookup_file() and only enter_file() if it does
3583 not already exist. If the file we get back is a double-colon then
3584 add this variable to the "root" double-colon target.
3586 * variable.c (initialize_file_variables): If this file is a
3587 double-colon target but is not the "root" target, then initialize
3588 the root and make the root's variable list the parent of our
3591 2002-09-13 Paul D. Smith <psmith@gnu.org>
3593 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3595 * hash.c (round_up_2): Get rid of a warning.
3597 2002-09-12 Paul D. Smith <psmith@gnu.org>
3599 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3600 so it doesn't complain about getloadavg.c.
3602 * commands.c (set_file_variables): Make sure we always alloca() at
3603 least 1 character for the value of $? (for '\0').
3605 2002-09-11 Paul D. Smith <psmith@gnu.org>
3607 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3608 macro to use RESULT instead of the incorrect _RESULT_.
3610 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3611 and atomic_readdir(). We need to #include dirent.h to get this to
3613 * misc.c (atomic_readdir): Fix typos.
3615 2002-09-10 Paul D. Smith <psmith@gnu.org>
3617 * read.c (eval): Expand variable lists given to export and
3618 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3619 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3621 * doc/make.texi (Variables/Recursion): Document this.
3622 (Conditional Syntax): And here.
3624 2002-09-09 Paul D. Smith <psmith@gnu.org>
3626 * configure.in: Check for memmove().
3628 2002-09-07 Paul D. Smith <psmith@gnu.org>
3630 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3631 Michael Sterrett <msterret@coat.com> reports that while it has
3632 SA_RESTART, it does not work properly.
3634 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3635 that invokes stat() and loops to do it again if it returns EINTR.
3636 (atomic_readdir): Ditto, with readdir().
3638 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3639 and readdir() to atomic_stat() and atomic_readdir().
3641 2002-09-04 Paul D. Smith <psmith@gnu.org>
3643 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3644 reports that GNU make sometimes doesn't recognize that targets can
3645 be made, when directories can be created as prerequisites. He
3646 reports that changing the order of predicates in the DEP->changed
3647 flag test so that lookup_file() is always performed, solves this
3650 2002-08-08 Paul D. Smith <psmith@gnu.org>
3652 * configure.in: Require a newer version of gettext.
3654 * misc.c (perror_with_name): Translate the format string (for
3655 right-to-left language support).
3656 (pfatal_with_name): Ditto.
3658 * main.c: Create a static array of strings to store the usage
3659 text. This is done to facilitate translations.
3660 (struct command_switch): Remove argdesc and description fields.
3661 (switches): Remove values for obsolete fields.
3662 (print_usage): Print each element of the usage array.
3664 * hash.c: Change function definitions to be K&R style.
3666 2002-08-02 Paul D. Smith <psmith@gnu.org>
3668 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3669 this one because it's too hard to get right. We'll look at it for
3671 * main.c (main): Don't create the .TARGETS variable.
3672 * variable.c (handle_special_var): Don't handle .TARGETS.
3674 2002-08-01 Paul D. Smith <psmith@gnu.org>
3676 * main.c (switches): Add a new option, -B (--always-make). If

3678 if they don't appear to be out of date.
3679 (always_make_flag): New flag.
3680 * make.h: Extern always_make_flag.
3681 * remake.c (update_file_1): Check always_make_flag; if it's set we
3682 will always rebuild any target we can, even if none of its
3683 prerequisites are newer.
3686 * doc/make.texi (Shell Function): Make it clear that make
3687 variables marked as "export" are not passed to instances of the
3690 Add new introspection variable .VARIABLES and .TARGETS.
3692 * variable.c (handle_special_var): New function. If the variable
3693 reference passed in is "special" (.VARIABLES or .TARGETS),
3694 calculate the new value if necessary. .VARIABLES is handled here:
3695 walk through the hash of defined variables and construct a value
3696 which is a list of the names. .TARGETS is handled by
3697 build_target_list().
3698 (lookup_variable): Invoke handle_special_var().
3699 * file.c (build_target_list): Walk through the hask of known files
3700 and construct a list of the names of all the ones marked as
3702 * main.c (main): Initialize them to empty (and as simple variables).
3703 * doc/make.texi (Special Variables): Document them.
3704 * NEWS: Mention them.
3706 * variable.h (struct variable): Add a new flag "exportable" which
3707 is true if the variable name is valid for export.
3708 * variable.c (define_variable_in_set): Set "exportable" when a new
3709 variable is defined.
3710 (target_environment): Use the "exportable" flag instead of
3711 re-checking the name here... an efficiency improvement.
3713 2002-07-31 Paul D. Smith <psmith@gnu.org>
3715 * config.h-vms.template: Updates to build on VMS. Thanks to
3716 Brian_Benning@aksteel.com for helping verify the build.
3717 * makefile.com: Build the new hash.c file.
3718 * hash.h: Use strcpmi(), not stricmp(), in the
3719 HAVE_CASE_INSENSITIVE_FS case.
3721 2002-07-30 Paul D. Smith <psmith@gnu.org>
3723 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3724 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3725 Reported by <Brian_Benning@aksteel.com>.
3727 2002-07-10 Paul D. Smith <psmith@gnu.org>
3729 * variable.c (pop_variable_scope): Remove variable made unused by
3730 new hash infrastructure.
3731 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3732 comparisons as well as name comparisons.
3733 * variable.h: Add a prototype for new hash_init_function_table().
3734 * file.c (lookup_file): Remove variables made unused by new hash
3736 * dir.c (directory_contents_hash_2): Missing return of hash value.
3737 (dir_contents_file_exists_p): Remove variables made unused by new
3738 hash infrastructure.
3741 Installed Greg McGary's integration of the hash functions from the
3742 GNU id-utils package:
3744 2002-07-10 Greg McGary <greg@mcgary.org>
3746 * scripts/functions/filter-out: Add literals to to the
3747 pattern space in order to add complexity, and trigger
3748 use of an internal hash table. Fix documentation strings.
3749 * scripts/targets/INTERMEDIATE: Reverse order of files
3750 passed to expected `rm' command.
3752 2002-07-10 Greg McGary <greg@mcgary.org>

3824 (find_char_unquote): Accept two char-constant stop chars, rather
3825 than a string constant, avoiding zillions of calls to strchr.
3826 Tighten inner search loops to test only for desired delimiters.

3844 2002-07-10 Paul D. Smith <psmith@gnu.org>
3846 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3847 prerequisite list. A real SysV make will expand the entire
3848 prerequisites list _twice_: we don't do that as it's a big
3849 backward-compatibility problem. We only replace those specific
3852 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3853 references left in the list of prerequisites. Check for .POSIX as
3854 we record targets, so we can disable non-POSIX behavior while
3855 reading makefiles as well as running them.
3856 (eval): Check the prerequisite list to see if we have anything
3857 that looks like a SysV prerequisite variable reference.
3859 2002-07-09 Paul D. Smith <psmith@gnu.org>
3861 * doc/make.texi (Prerequisite Types): Add a new section describing
3862 order-only prerequisites.
3864 * read.c (uniquize_deps): If we have the same file as both a
3865 normal and order-only prereq, get rid of the order-only prereq,
3866 since the normal one supersedes it.
3868 2002-07-08 Paul D. Smith <psmith@gnu.org>
3870 * AUTHORS: Added Greg McGary to the AUTHORS file.
3871 * NEWS: Blurbed order-only prerequisites.
3872 * file.c (print_file): Show order-only deps properly when printing
3875 * maintMakefile: Add "update" targets for wget'ing the latest
3876 versions of various external files. Taken from Makefile.maint in
3879 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3880 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3882 2002-07-07 Paul D. Smith <psmith@gnu.org>
3884 * po/*.po: Remove. We'll use wget to retrieve them at release
3887 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3888 rather than a shell you get an exception. Make sure we look up
3889 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3891 * remake.c (notice_finished_file): Fix handling of -t flag.
3892 Patch provided by Henning Makholm <henning@makholm.net>.
3894 * implicit.c (pattern_search): Some systems apparently run short
3895 of stack space, and using alloca() in this function caused an
3896 overrun. I modified it to use xmalloc() on the two variables
3897 which seemed like they might get large. Fixes Bug #476.
3899 * main.c (print_version): Update copyright notice to conform with
3901 (print_usage): Update help output.
3903 * function.c (func_eval): Create a new make function, $(eval
3904 ...). Expand the arguments, put them into a buffer, then invoke
3905 eval_buffer() on the resulting string.
3906 (func_quote): Create a new function, $(quote VARNAME). Inserts
3907 the value of the variable VARNAME without expanding it any
3910 * read.c (struct ebuffer): Change the linebuffer structure to an
3911 "eval buffer", which can be either a file or a buffer.
3912 (eval_makefile): Move the code in the old read_makefile() which
3913 located a makefile into here: create a struct ebuffer with that
3914 information. Have it invoke the new function eval() with that
3916 (eval_buffer): Create a new function that creates a struct ebuffer
3917 that holds a string buffer instead of a file. Have it invoke
3918 eval() with that ebuffer.
3919 (eval): New function that contains the guts of the old
3920 read_makefile() function: this function parses makefiles. Obtains
3921 data to parse from the provided ebuffer. Some modifications to
3922 make the flow of the function cleaner and clearer. Still could
3923 use some work here...
3924 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3925 contents of the define/endef variable from the ebuffer.
3926 (readstring): Read the next line from a string-style ebuffer.
3927 (readline): Read the next line from an ebuffer. If it's a string
3928 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3931 * dep.h (eval_buffer): Prototype eval_buffer();
3933 * variable.c (do_variable_definition): Make sure that all
3934 non-target-specific variables are registered in the global set.
3935 If we're invoked from an $(eval ...) we might be inside a $(call
3936 ...) or other function which has pushed a variable scope; we still
3937 want to define our variables from evaluated makefile code in the
3940 2002-07-03 Greg McGary <greg@mcgary.org>
3942 * dep.h (struct dep) [ignore_mtime]: New member.
3943 [changed]: convert to a bitfield.
3944 * implicit.c (pattern_search): Zero ignore_mtime.
3945 * main.c (main, handle_non_switch_argument): Likewise.
3946 * rule.c (convert_suffix_rule): Likewise.
3947 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3948 (read_makefile): Parse '|' in prerequisite list.
3949 (uniquize_deps): Consider ignore_mtime when comparing deps.
3950 * remake.c (update_file_1, check_dep): Don't force remake for
3951 dependencies that have d->ignore_mtime.
3952 * commands.c (FILE_LIST_SEPARATOR): New constant.
3953 (set_file_variables): Don't include a
3954 prerequisite in $+, $^ or $? if d->ignore_mtime.
3957 2002-06-18 Paul D. Smith <psmith@gnu.org>
3959 * make.texinfo: Updates for next revision. New date/rev/etc.
3960 Recreate all Info menus. Change license on the manual to the GNU
3961 Free Documentation License. A number of typos.
3962 (Variables Simplify): Don't use "-" before it's defined.
3963 (Automatic Prerequisites): Rewrite the target example to work
3964 properly if the compile fails. Remove incorrect comments about
3965 how "set -e" behaves.
3966 (Text Functions): Move the "word", "wordlist", "words", and
3967 "firstword" functions here, from "File Name Functions".
3968 * make-stds.texi: Update from latest GNU version.
3969 * fdl.texi: (created) Import the latest GNU version.
3971 2002-06-06 Paul D. Smith <psmith@gnu.org>
3973 * variable.c (do_variable_definition): New function: extract the
3974 part of try_variable_definition() that actually sets the value
3975 into a separate function.
3976 (try_variable_definition): Call do_variable_definition() after
3977 parsing the variable definition string.
3978 (define_variable_in_set): Make the name argument const.
3980 * variable.h (enum variable_flavor): Make public.
3981 (do_variable_definition): Create prototype.
3983 * read.c (read_all_makefiles): Create a new built-in variable,
3985 (read_makefile): Add each makefile read in to this variable value.
3987 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
3989 * Makefile.DOS.template: Tweak according to changes in the
3990 distribution. Add back the dependencies of *.o files.
3992 * configh.dos.template: Synchronize with config.h.in.
3994 2002-05-09 Paul D. Smith <psmith@gnu.org>
3996 * file.c (file_timestamp_now): Use K&R function declaration.
3998 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
3999 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4000 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4001 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4002 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4003 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4004 nlist.n_name is a pointer rather than an array.
4006 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4007 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4008 * configure.in: Use it instead of the old version.
4010 * main.c (main): Prefer setvbuf() to setlinebuf().
4012 2002-05-08 Paul D. Smith <psmith@gnu.org>
4014 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4015 (loadavg_LDADD): Ditto.
4017 2002-04-29 Paul D. Smith <psmith@gnu.org>
4019 * expand.c (recursively_expand_for_file): Rename
4020 recursively_expand() to recursively_expand_for_file() and provide
4021 an extra argument, struct file. If the argument is provided, set
4022 the variable scope to that of the file before expanding.
4023 * variable.h (recursively_expand): Make this a macro that invokes
4024 recursively_expand_for_file() with a NULL file pointer.
4025 * variable.c (target_environment): Call the renamed function and
4026 provide the current file context.
4027 Fixes Debian bug #144306.
4029 2002-04-28 Paul D. Smith <psmith@gnu.org>
4031 Allow $(call ...) user-defined variables to be self-referencing
4032 without throwing an error. Allows implementation of transitive
4033 closures, among other possibly useful things.
4034 Requested by: Philip Guenther <guenther@sendmail.com>
4036 * variable.h (struct variable): Add a new field: exp_count, and
4037 new macros to hold its size and maximum value.
4038 (warn_undefined): Make this a macro.
4039 * variable.c (define_variable_in_set): Initialize it.
4040 * expand.c (recursively_expand): If we detect recursive expansion
4041 of a variable, check the exp_count field. If it's greater than 0
4042 allow the recursion and decrement the count.
4043 (warn_undefined): Remove this (now a macro in variable.h).
4044 * function.c (func_call): Before we expand the user-defined
4045 function, modify its exp_count field to contain the maximum
4046 number of recursive calls we'll allow. After the call, reset it
4049 2002-04-21 Paul D. Smith <psmith@gnu.org>
4051 Modified to use latest autoconf (2.53), automake (1.6.1), and
4052 gettext (0.11.1). We're using gettext's new "external" support,
4053 to avoid including libintl source with GNU make.
4055 * README.cvs: New file. Explain how to build GNU make from CVS.
4057 * configure.in: Modify checking for the system glob library.
4058 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4059 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4060 etc. will manage it correctly). Set an automake conditional
4061 USE_LOCAL_GLOB to decide whether to compile the glob library.
4063 * getloadavg.c (main): Include make.h in the "TEST" program to
4066 * Makefile.am: Remove special rules for loadavg. Replace them
4067 with Automake capabilities for building extra programs.
4069 * signame.c: This file does nothing if the system provide
4070 strsignal(). If not, it implements strsignal(). If the system
4071 doesn't define sys_siglist, then we make our own; otherwise we use
4073 * signame.h: Removed.
4075 * main.c (main): No need to invoke signame_init(). Update copyright.
4077 * ABOUT-NLS: Removed.
4078 * gettext.c: Removed.
4079 * gettext.h: Get a simplified copy from the gettext package.
4081 * i18n/*.po: Moved to po/.
4084 * config/*: Created. Contains package configuration helper files.
4085 * config.guess, config.sub: Moved to config directory.
4087 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4088 Rework to use new-style autoconf features. Use the "external"
4089 mode for gettext. Make the build.sh config file conditional on
4090 whether build.sh.in exists, to avoid autoconf errors.
4091 * acinclude.m4: Removed almost all macros as being obsolete.
4092 Rewrote remaining macros to use AC_DEFINE.
4093 * acconfig.h: Removed.
4095 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4096 conditional to handle customs support. Remove special handling
4099 2002-04-20 Paul D. Smith <psmith@gnu.org>
4101 * function.c (func_call): Don't mark the argument variables $1,
4102 etc. as recursive. They've already been fully expanded so
4103 there's no need to do it again, and doing so strips escaped $'s.
4104 Reported by Sebastian Glita <glseba@yahoo.com>.
4106 * remake.c (notice_finished_file): Walk through double-colon
4107 entries via the prev field, not the next field!
4108 Reported by Greg McGary <greg@mcgary.org>.
4110 * main.c (main): If the user specifies -q and asks for a specific
4111 target which is a makefile, we got an assert. In that case it
4112 turns out we should continue normally instead.
4114 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4116 * i18n/he.po: Installed a new translation.
4118 2002-01-07 Paul D. Smith <psmith@gnu.org>
4120 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4122 2001-12-04 Paul D. Smith <psmith@gnu.org>
4124 * i18n/ja.po: Installed an updated translation.
4126 2001-09-06 Paul Eggert <eggert@twinsun.com>
4128 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4129 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4131 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4133 (main): Get rid of any avoidable limit on stack size.
4135 2001-09-04 Paul D. Smith <psmith@gnu.org>
4137 * i18n/da.po: Installed an updated translation.
4139 2001-08-03 Paul D. Smith <psmith@gnu.org>
4141 * i18n/fr.po: Installed an updated translation.
4142 Resolves Debian bug #106720.
4144 2001-06-13 Paul D. Smith <psmith@gnu.org>
4146 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4149 2001-06-11 Paul D. Smith <psmith@gnu.org>
4151 * i18n/ko.po: Installed a new translation.
4153 2001-05-06 Paul D. Smith <psmith@gnu.org>
4155 Modify the EINTR handling.
4157 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4158 the way in which we manage the file descriptor/signal handler race
4159 trap to be more efficient.
4161 2001-05-06 Paul Eggert <eggert@twinsun.com>
4163 Restart almost all system calls that are interrupted, instead
4164 of worrying about EINTR. The lone exception is the read() for
4167 * configure.in (HAVE_SA_RESTART): New macro.
4168 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4169 * main.c (main): Use SA_RESTART instead of the old,
4170 nonstandard SA_INTERRUPT.
4172 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4173 * main.c (bsd_signal): New function or macro,
4174 if the implementation doesn't supply it.
4175 (The bsd_signal function will be in POSIX 1003.1-200x.)
4176 (HANDLESIG): Remove.
4177 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4179 * make.h (EINTR_SET): Remove.
4180 (SA_RESTART): New macro.
4182 * arscan.c (ar_member_touch): Don't worry about EINTR.
4183 * function.c (func_shell): Likewise.
4184 * job.c (reap_children, free_child, new_job): Likewise.
4185 * main.c (main): Likewise.
4186 * remake.c (touch_file, name_mtime): Likewise.
4188 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4189 if fstat failed with errno!=EINTR, the error was ignored.
4191 * job.c (set_child_handler_action_flags): New function.
4192 (new_job): Use it to temporarily clear the SIGCHLD action flags
4193 while reading the token.
4195 2001-05-02 Paul D. Smith <psmith@gnu.org>
4197 * job.c (start_job_command): Don't add define/endef per-line flags
4198 to the top-level flags setting.
4200 2001-04-03 Paul D. Smith <psmith@gnu.org>
4202 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4203 bit on error, so check for odd return values, not non-0 return
4205 (VMS_get_member_info): Calculate the timezone differences correctly.
4206 Reported by John Fowler <jfowler@nyx.net>.
4209 2001-03-14 Paul D. Smith <psmith@gnu.org>
4211 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4212 value before invoking define_variable().
4213 Reported by John Fowler <jfowler@nyx.net>.
4215 2001-02-07 Paul D. Smith <psmith@gnu.org>
4217 * read.c (record_target_var): If we reset the variable due to a
4218 command-line variable setting overriding it, turn off the "append"
4221 2001-01-17 Paul D. Smith <psmith@gnu.org>
4223 * variable.c (lookup_variable) [VMS]: When getting values from the
4224 environment, allocate enough space for the _value_ plus escapes,
4225 not enough space for the name plus escapes :-/.
4226 Reported by John Fowler <jfowler@nyx.net>.
4228 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4229 warnings that make generates, so it doesn't look like an error.
4230 Reported by Karl Berry <karl@gnu.org>.
4233 Fix for PR/2020: Rework appended target-specific variables. I'm
4234 fairly confident this algorithm is finally correct.
4236 * expand.c (allocated_variable_append): Rewrite. Instead of
4237 expanding each appended variable then adding all the expanded
4238 strings together, we append all the unexpanded values going up
4239 through the variable set contexts, then expand the final result.
4240 This behaves just like non-target-specific appended variable
4241 values, while the old way didn't in various corner cases.
4242 (variable_append): New function: recursively append the unexpanded
4243 value of a variable, walking from the outermost variable scope to
4245 * variable.c (lookup_variable): Remove the code that looked up the
4246 variable set list if the found variable was "append". We don't
4248 (lookup_variable_in_set): Make this non-static so we can use it
4250 (try_variable_definition): Use lookup_variable_in_set() rather
4251 than faking out current_variable_set_list by hand (cleanup).
4252 * variable.h: Add a prototype for the now non-static
4253 lookup_variable_in_set().
4255 2000-11-17 Paul D. Smith <psmith@gnu.org>
4257 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4258 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4259 before throwing a fit.
4261 2000-11-17 Paul D. Smith <psmith@gnu.org>
4263 * read.c (readline): CRLF calculations had a hole, if you hit the
4264 buffer grow scenario just right. Reworked the algorithm to avoid
4265 the need for len or lastlen at all. Problem description with
4266 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4268 2000-10-24 Paul D. Smith <psmith@gnu.org>
4270 * gettext.c (SWAP): Declare this with the prototype, otherwise
4271 some systems don't work (non-32-bit? Reported for Cray T3E).
4272 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4274 2000-10-05 Paul D. Smith <psmith@gnu.org>
4276 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4277 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4279 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4281 2000-09-22 Paul D. Smith <psmith@gnu.org>
4283 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4284 parts of the real gettext.h here, and we expect to really include
4285 the real gettext.h later. If we keep this #define, it's ignored.
4287 2000-09-21 Paul D. Smith <psmith@gnu.org>
4289 * main.c (log_working_directory): Rework the text to use complete
4290 sentences, to make life simpler for the translators.
4292 2000-08-29 Paul D. Smith <psmith@gnu.org>
4294 * file.c (remove_intermediates): Print a debug message before we
4295 remove intermediate files, so the user (if she uses -d) knows
4298 2000-08-21 Paul D. Smith <psmith@gnu.org>
4300 * variable.c (try_variable_definition): Change how we handle
4301 target-specific append variable defns: instead of just setting the
4302 value, expand it as an append _but_ only within the current
4303 target's context. Otherwise we lose all but the last value if the
4304 variable is appended more than once within the current target
4305 context. Fixes PR/1831.
4307 2000-08-16 Paul D. Smith <psmith@gnu.org>
4309 * function.c (func_shell): Nul-terminate the buffer before
4310 printing an exec error message (just in case it's not!).
4311 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4313 2000-07-25 Paul D. Smith <psmith@gnu.org>
4315 * job.c (construct_command_argv_internal): Add "~" to the list of
4316 sh_chars[] which disallow optimizing out the shell call.
4318 2000-07-23 Paul Eggert <eggert@twinsun.com>
4320 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4321 supersedes --disable-nsec-timestamps.
4322 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4323 * README: Remove --disable-nsec-timestamps.
4325 * filedef.h (struct file.low_resolution_time): New member.
4326 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4327 * remake.c (update_file_1):
4328 Avoid spurious rebuilds due to low resolution time stamps,
4329 generalizing the earlier code that applied only to archive members.
4330 (f_mtime): Archive members always have low resolution time stamps.
4332 * configure.in: Remove --disable-nsec-timestamps, as this has
4333 been superseded by .LOW_RESOLUTION_TIME.
4335 2000-07-23 Paul Eggert <eggert@twinsun.com>
4337 * configure.in (enable_nsec_timestamps): Renamed from
4338 make_cv_nsec_timestamps, since enable/disable options
4339 shouldn't be cached.
4341 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4342 and Paul Eggert <eggert@twinsun.com>
4344 * file.c (file_timestamp_now):
4345 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4346 so that clock_gettime is not linked unless needed.
4348 * filedef.h (FILE_TIMESTAMP_HI_RES):
4349 Remove definition; "configure" now does this.
4351 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4352 to before high resolution file timestamp check,
4353 since that check now uses uintmax_t.
4354 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4355 high resolution file timestamps.
4356 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4357 so that we don't link in clock_gettime unnecessarily.
4359 2000-07-17 Paul D. Smith <psmith@gnu.org>
4361 * i18n/ja.po: New version of the translation file.
4363 2000-07-07 Paul D. Smith <psmith@gnu.org>
4365 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4366 the offset calculation.
4367 (name_mtime): Replace EINTR test with EINTR_SET macro.
4369 2000-07-07 Paul Eggert <eggert@twinsun.com>
4373 * remake.c (update_file_1):
4374 Avoid spurious rebuilds of archive members due to their
4375 timestamp resolution being only one second.
4376 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4377 the clock's resolution being lower than file timestamps'.
4378 When warning about future timestamps, report only the discrepancy,
4379 not the absolute value of the timestamp and the current time.
4381 * file.c (file_timestamp_now): New arg RESOLUTION.
4382 * filedef.h (file_timestamp_now): Likewise.
4383 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4385 2000-07-05 Paul D. Smith <psmith@gnu.org>
4387 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4388 to listp. Fixes PR/1793.
4390 2000-06-26 Paul Eggert <eggert@twinsun.com>
4392 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4394 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4396 * remake.c (f_mtime): Remove unused var memtime.
4398 2000-06-25 Martin Buchholz <martin@xemacs.org>
4400 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4401 Ran spell-check on make.texinfo.
4403 2000-06-23 Paul D. Smith <psmith@gnu.org>
4405 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4406 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4407 * make.h: Define these macros.
4409 * Version 3.79.1 released.
4411 * configure.in: Add a new option, --disable-nsec-timestamps, to
4412 avoid using sub-second timestamps on systems that support it. It
4413 can lead to problems, e.g. if your makefile relies on "cp -p".
4414 * README.template: Document the issue with "cp -p".
4416 * config.guess, config.sub: Updated.
