616 2010-07-01 Paul Smith <psmith@gnu.org>
618 * main.c (main): Append optional features using separate calls.

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

683 the VPATH_SEARCH call.
685 * doc/make.texi (Directory Search for Link Libraries): Describe the

775 2009-10-03 Paul Smith <psmith@gnu.org>
777 * make.h: Include <alloca.h> even on systems where __GNUC__ is

836 * doc/make.texi (Double-Colon): Mention that pattern rules with
837 double-colons have a different meaning. Savannah bug #27497.
839 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
841 * configh.dos.template: Remove unconditional definition of
842 SYS_SIGLIST_DECLARED.
843 Include <sys/version.h> because ports of GCC 4.3.0 and later no
844 longer include it, so macros like __DJGPP_MINOR__ are no longer
845 defined automatically.
847 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
848 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
849 instead of using the hardcoded ones.
850 (SUBDIRS): doc subdir added.
851 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
852 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
853 create html formated docs. texi2html may not be ported to DOS.
854 (make.info, make.dvi, make.ps, make.html): Make targets depend on
856 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
857 -I switch to look in ./ instead of ./doc.
858 (html): Target depend on html-recursive instead of make_1.html.
859 (make_1.html): Removed.
860 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.

863 (mostlyclean-recursive, clean-recursive, distclean-recursive)
864 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
865 (tags-recursive): Allow for more than one subdir in the build
867 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
868 targets. Enter into doc/ to produce the targets.
869 (all-am): $(INFO_DEPS) replaced by info.
871 2009-09-26 Paul Smith <psmith@gnu.org>
873 * read.c (record_files): Use free_ns() to free struct nameseq.
876 * rule.c (freerule): Use free_dep_chain().
878 * read.c (record_files): Free FILENAMES chain for implicit rules.
879 (eval): Static pattern targets go into the string cache.
881 * function.c (string_glob): Free NAME in the nameseq chain.
883 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
885 * implicit.c (pattern_search): Terminate early if we haven't
886 found any rules to try (performance improvement).
888 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
890 * implicit.c (pattern_search): Merge three parallel arrays,
891 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
892 of struct TRYRULE. In the old version the latter two arrays
893 had insufficient length.
895 2009-09-24 Paul Smith <psmith@gnu.org>
897 * implicit.c (pattern_search): Add back support for order-only
898 prerequisites for secondary expansion implicit rules, that were
899 accidentally dropped. If we find a "|", enable order-only mode
900 and set IGNORE_MTIME on all deps that are seen afterward.
901 (pattern_search): Fix memory leaks: for intermediate files where
902 we've already set the file variable and pattern variable sets, be
903 sure to either save or free them as appropriate.
905 2009-09-23 Paul Smith <psmith@gnu.org>
907 Rework the way secondary expansion is stored, for efficiency.
908 This changes secondary expansion so that ONLY WHEN we know we have
909 a possibility of needing secondary expansion, do we defer the
910 secondary expansion. This means more parsing the deps but we use
911 a lot less memory (due to the strcache). Also, this fixes
914 * read.c (eval): Don't parse the dep string here anymore.
915 (record_files): Take the dep argument as an unparsed string. If
916 secondary expansion is enabled AND the prereq string has a '$' in
917 it, then set NEED_2ND_EXPANSION and keep the entire string.
918 Otherwise, parse the dep string here to construct the dep list
919 with the names in the strcache.
921 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
922 duplicate the name string (others are in the strcache).
924 * implicit.c: Remove struct idep and free_idep_chain(): unused.
925 (struct patdeps): New structure to store prereq information.
926 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
927 which prerequisites need expansion, and expand only those.
929 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
930 and enter_prereqs(). split_prereqs() takes a fully-expanded string
931 and splits it into a DEP list, handling order-only prereqs.
932 (enter_prereqs): This function enters a list of DEPs into the file
933 database. If there's a stem defined, expand any pattern chars.
934 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
935 set. Use the above functions.
936 (snap_deps): Only perform second expansion on prereqs that need it,
937 as defined by the NEED_2ND_EXPANSION flag.
938 (print_prereqs): New function to print the prereqs
939 (print_file): Call print_prereqs() rather than print inline.
941 * hash.h (STRING_COMPARE): Take advantage of strcache() by
943 (STRING_N_COMPARE): Ditto.
944 (ISTRING_COMPARE): Ditto.
946 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
947 (parse_file_seq): Return void*

958 2009-09-16 Paul Smith <psmith@gnu.org>
960 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
962 * dep.h: Create alloc_dep() / free_dep() macros.
964 * implicit.c (pattern_search): Take advantage of the new
965 parse_file_seq() to add the directory prefix to each prereq.
967 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
968 all. Avoid reversing chains. Support adding prefixes.
969 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
970 cached/non-cached results.
971 (eval): Remove multi_glob() & invoke new parse_file_seq().
972 * rule.c (install_pattern_rule): Ditto.
973 * main.c (main): Ditto.
974 * implicit.c (pattern_search): Ditto.
975 * function.c (string_glob): Ditto.
976 * file.c (parse_prereqs): Ditto.
977 * default.c (set_default_suffixes): Ditto.
979 * variable.c (parse_variable_definition): Don't run off the end of
980 the string if it ends in whitespace (found with valgrind).
982 * commands.c (set_file_variables): Keep space for all targets in
983 $? if -B is given (found with valgrind).
985 2009-09-15 Paul Smith <psmith@gnu.org>
987 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
988 (xcalloc): Add new function.
989 * make.h: New declarations.
991 * ar.c (ar_glob_match): New calling method for concat().
992 * main.c (main): Ditto.

1000 * ar.c (ar_glob_match): Use xcalloc().
1001 * dir.c (file_impossible): Ditto.
1002 * file.c (enter_file): Ditto.
1003 * job.c (new_job): Ditto.
1004 * read.c (parse_file_seq): Ditto.
1005 * vmsfunctions.c (opendir): Ditto.
1007 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)

1020 before looping through them. Fixes Savannah bug #21824.
1022 * doc/make.texi (Wildcard Examples): Clarify when objects is
1023 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1024 (Include): Clarify the behavior of -include.
1025 Fixes Savannah bug #18963.
1027 2009-08-01 Paul Smith <psmith@gnu.org>
1029 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1030 etc. come on the command line. Fixes Savannah bug #27093.
1032 * expand.c (expand_argument): If the argument is large enough use
1033 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1035 * variable.c (do_variable_definition): Avoid using alloca() to
1036 hold values, which can be large. Fixes Savannah bug #23960.
1038 * job.c (new_job): Use memmove() instead of strcpy() since both
1039 pointers are in the same memory block. Fixes Savannah bug #27148.
1040 Patch by Petr Machata.
1042 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1044 * job.c (construct_command_argv_internal): Add "ulimit" and

1049 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1050 that set make_cv_sys_gnu_glob, so they are also correctly set
1051 when the cache has been populated before.
1053 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1055 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1056 exist, as realpath(3) does where it's supported.
1058 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1060 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1061 (abspath): Support systems that define HAVE_DOS_PATHS (have
1062 drive letters in their file names). Use IS_PATHSEP instead of a
1063 literal '/' comparison. Fixes Savannah bug #26886.
1065 2009-06-14 Paul Smith <psmith@gnu.org>
1067 * remake.c (update_file_1): Remember the original file we marked
1068 as updating, so we can clear that flag again. If we find a target
1069 via vpath, FILE might change.
1070 (check_dep): Ditto. Fixes Savannah bug #13529.
1071 Patch by Reid Madsen <reid.madsen@tek.com>.
1073 2009-06-13 Paul Smith <psmith@gnu.org>
1075 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1076 included by MAKEFILES cannot give default goals.
1077 * read.c (eval): If set_default is not set, pass the no-default-goal
1078 value when we read included makefiles. Fixes Savannah bug #13401.
1080 * ar.c (ar_name): Ensure that targets with empty parens aren't
1081 considered archive member references: archive members must have a
1082 non-empty "member" string. Fixes Savannah bug #18435.
1084 * function.c (string_glob): Rely on multi_glob() to determine
1085 whether files exist or not. Remove call to file_exists_p() which
1086 is not always correct. Fixes Savannah bug #21231.
1087 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1088 then only files that really exist will be returned.
1089 * dep.h: Add new argument to multi_glob().
1090 * rule.c (install_pattern_rule): Ditto.
1091 * read.c (eval): Ditto.
1092 * main.c (main): Ditto.
1093 * implicit.c (pattern_search): Ditto.
1094 * file.c (parse_prereqs): Ditto.
1095 * default.c (set_default_suffixes): Ditto.
1097 2009-06-09 Paul Smith <psmith@gnu.org>
1099 * commands.c (set_file_variables): If always_make_flag is set,
1100 always add the prereq to $?. Fixes Savannah bug #17825.
1102 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1103 to rebuild the deps of all the also_make targets for that file.
1104 Fixes Savannah bug #19108.
1106 * implicit.c (pattern_search): Undo test for is_target, added by
1107 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1108 Rule Search Algorithm". Fixes Savannah bug #17752.
1110 * main.c (clean_jobserver): Clear the jobserver_fds options and
1111 set job_slots to the default when we clean up.
1112 (define_makeflags): Return the new MAKEFLAGS value.
1113 (main): Reset MAKEFLAGS in the environment when we re-exec.
1114 Fixes Savannah bug #18124.
1116 2009-06-08 Paul Smith <psmith@gnu.org>
1118 * read.c (eval): Collapse continuations post-semicolon on target-
1119 specific variables. Fixes Savannah bug #17521.
1121 2009-06-07 Paul Smith <psmith@gnu.org>
1123 * job.c (reap_children): For older systems without waitpid() (are
1124 there any of these left?) run wait(2) inside EINTRLOOP to handle
1125 EINTR errors. Fixes Savannah bug #16401.
1127 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1129 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1131 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1132 not the end, to catch second expansion $(eval ...) defining new
1133 target/prereq relationships during snap_deps.
1134 Fixes Savannah bug #24622.
1136 * read.c (record_files): The second-expansion "f->updating" hack
1137 was not completely correct: if assumed that the target with
1138 commands always had prerequisites; if one didn't then the ordering
1139 was messed up. Fixed for now to use f->updating to decide whether
1140 to preserve the last element in the deps list... but this whole
1141 area of constructing and reversing the deps list is too confusing
1142 and needs to be reworked. Fixes Savannah bug #21198.
1144 2009-06-06 Paul Smith <psmith@gnu.org>
1146 * hash.c (hash_insert): Remove useless test for NULL.
1147 Fixes Savannah bug #21823.
1149 * make.h: Move SET_STACK_SIZE determination to make.h.
1150 * main.c (main): New global variable, STACK_LIMIT, holds the
1151 original stack limit when make was started.
1152 * job.c (start_job_command): Reset the stack limit, if we changed it.
1153 Fixes Savannah bug #22010.
1155 * remake.c (check_dep): Only set the target's state to not-started
1156 if it's not already running. Found this while testing -j10 builds
1157 of glibc: various targets were being rebuilt multiple times.
1158 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1161 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1162 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1165 2009-06-04 Paul Smith <psmith@gnu.org>
1167 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1169 * maintMakefile: Modify access of config and gnulib Savannah
1170 modules to use GIT instead of CVS.
1172 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1173 Fixes Savannah bug #24655.
1175 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1176 this can happen during some invocations of $(eval ...) for example.
1177 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1179 2009-06-02 Paul Smith <psmith@gnu.org>
1181 * configure.in: Check for fileno()
1182 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1183 for the makefile file so invocations of $(shell ...) don't inherit it.
1184 Fixes Savannah bug #24277.
1186 2009-06-01 Paul Smith <psmith@gnu.org>
1188 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1189 expansion was handled incorrectly. Rework the default goal
1190 handling to save the variable only. Remove default_goal_file and
1192 * read.c (eval): Check default_goal_var, not default_goal_name.
1193 * read.c (record_target_var): Don't check default_goal_file here.
1195 2009-05-31 Paul Smith <psmith@gnu.org>
1197 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1198 it, and if the multi_glob() returns nothing (say it expanded to
1199 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1201 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1202 $(and ..) to the reference. Fixes Savannah bug #25694.
1204 * make.1: Be clear that some recipes will be executed even with -n.
1205 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1207 * doc/make.texi (Override Directive): Make more clear how
1208 overrides and appends interact.
1209 Elucidates part of Savannah bug #26207.
1211 * read.c (record_target_var): Don't reset the origin on
1212 target-specific variables; try_variable_definition() will handle
1213 this correctly. Fixes Savannah bug #26207.
1215 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1216 Fixes Savannah bug #25712.
1218 * implicit.c (pattern_search): Keep a pointer to the beginning of
1219 the filename and save that instead of the constructed pointer.
1220 Fixes Savannah bug #26593.
1221 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1223 2009-05-30 Paul Smith <psmith@gnu.org>
1225 * doc/make.texi (Multi-Line): Add a description of the new abilities
1226 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1227 "command sequence" vs. "recipe" syntax.
1228 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1229 after a define, to create variables with those flavors.
1231 2009-05-25 Paul Smith <psmith@gnu.org>
1233 Reworked the parser for variable assignments to allow multiple
1234 modifiers, and in any order. Also allows variable and
1235 prerequisites to be modifier names ('export', 'private', etc.)
1237 * NEWS: Add notes about user-visible changes.
1239 * read.c (struct vmodifiers): Remember what modifiers were seen.
1240 (parse_var_assignment): New function to parse variable assignments.
1241 (eval): Call the new function. Handle variable assignments earlier.
1243 * variable.c (parse_variable_definition): Only parse; don't create var.
1244 (assign_variable_definition): Call parse, then create the var.
1246 2009-05-24 Paul Smith <psmith@gnu.org>
1248 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1249 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1251 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1253 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1254 Fixes Savannah bug #25412.
1256 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1257 prototype for xmalloc.
1258 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1259 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1260 Loop over an array of extensions, instead of duplicating the same
1261 code inline. Use SearchPath followed by CreateFile, instead of
1262 the obsolete OpenFile. Fixes Savannah bug #17277.
1263 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1264 to `find_file'. Fixes Savannah bug #25662.
1266 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1268 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1269 Fixes Savannah bug #20495.
1271 2009-02-28 Ralf Wildenhues <address@hidden>
1273 * doc/make.texi (Instead of Execution): Document interaction of
1274 -t with phony targets.
1276 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1278 Introduce a new keyword "private" which applies to target-specific
1279 variables and prevents their values from being inherited.
1281 * variable.h (struct variable): Add private_var flag to each variable.
1282 Add a flag to specify which list entry switches to the parent target.
1283 * variable.c (define_variable_in_set): Initialize private_var flag.
1284 (lookup_variable): Skip private variables in parent contexts.
1285 (initialize_file_variables): Set next_is_parent appropriately.

1296 * make.h: Rename savestring to xstrndup.
1297 * commands.c (chop_commands): Ditto.
1298 * function.c (func_foreach): Ditto.
1299 * read.c (eval, record_files): Ditto.
1300 * variable.c (define_variable_in_set): Ditto.
1302 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1304 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1307 * w32/subproc/build.bat (GCCBuild): Likewise.
1309 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1311 * job.c (construct_command_argv_internal): Avoid extra backslash
1312 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1315 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1317 * README.W32.template: Remove obsolete text about non-support for
1318 -jN without Unixy shell. Remove obsolete text about not supplying
1319 Visual Studio project files (we do supply them). Modify text to
1320 prefer GCC builds to MSC builds.
1322 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1324 * doc/make.texi (Empty Targets): Fix typo.
1326 2008-03-27 Paul Smith <psmith@gnu.org>
1328 Fix Savannah bug #22379:
1329 * ar.c (ar_glob_match): Zero the allocated structure.
1330 * read.c (parse_file_seq): Ditto.
1332 2008-03-08 Brian Dessent <brian@dessent.net>
1334 * maintMakefile: Update Translation Project location.
1336 2008-01-26 Eli Zaretskii <eliz@gnu.org>
1338 * variable.c (target_environment): Don't use shell_var if its
1339 `value' field is NULL.
1341 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1343 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1345 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1346 (TEXINFOS): Value changed to `doc/make.texi'.
1347 (.SUFFIXES): Use .texi instead of .texinfo.
1348 (make.info, make.dvi): Depend on doc/make.texi.
1349 (.texi.info): New target, instead of ".texinfo.info". Change -I
1350 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1351 (.texi): New target, instead of ".texinfo". Change -I switch to
1352 $(MAKEINFO) to look in doc/. Use --no-split.
1353 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1354 switch to $(MAKEINFO) to look in doc/.
1355 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1356 "*.i[0-9][0-9]" (due to --no-split above).
1357 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1358 (html, make_1.html): New targets.
1359 (.PHONY): Add "html".
1360 (.SUFFIXES): Add .html.
1362 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1364 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1365 HAVE_DECL_SYS_SIGLIST.
1367 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1368 build does not use child_execute_job.
1370 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1371 export the SHELL environment variable to the child.
1373 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1375 * config.h.W32: Include sys/types.h.
1376 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1378 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
1379 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
1382 2007-11-04 Paul Smith <psmith@gnu.org>
1384 * doc/make.texi: Convert references to "commands", "command
1385 lines", and "command script" to "recipe".
1387 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
1390 2007-10-27 Bruno Haible <bruno@clisp.org>
1392 * remake.c (f_mtime): Print time difference values between 100 and
1393 ULONG_MAX in fixed-point notation rather than in exponention notation.
1395 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1397 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1398 a more complex value than a simple shell: if it's not a default
1399 shell now then expand it and see if is a default shell then.
1401 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1403 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1404 pathnames, with const strings.
1405 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1406 from the template (used for building from CVS, not a dist).
1408 2007-10-10 Paul Smith <psmith@gnu.org>
1410 * make.h: Add a prototype for w32_kill() (change suggested by
1411 Yongwei Wu <wuyongwei@gmail.com>).
1413 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1415 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1416 directories in Path.
1418 2007-09-12 Paul Smith <psmith@gnu.org>
1420 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
1421 Provided by Diego Biurrun <diego@biurrun.de>
1422 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1423 Provided by Diego Biurrun <diego@biurrun.de>
1425 2007-09-11 Paul Smith <psmith@gnu.org>
1427 * doc/make.texi (Special Variables): Moved this into the "How to
1428 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1429 (MAKEFILE_LIST) No longer a section; this was added into the
1430 "Special Variables" section.
1431 (Rule Introduction): Reference .RECIPEPREFIX.
1432 (Simple Makefile): Ditto.
1433 (Rule Syntax): Ditto.
1434 (Command Syntax): Ditto.
1435 (Error Messages): Ditto.
1437 2007-09-10 Paul Smith <psmith@gnu.org>
1439 * commands.c (print_commands): Don't print an extra line in the
1440 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1442 * read.c (construct_include_path): Add the full string to the cache; we
1443 were chopping the last char.
1445 * NEWS: Announce the .RECIPEPREFIX special variable.
1446 * variable.c (lookup_special_var): Rename from handle_special_var().
1447 (lookup_variable): Call the new name.
1448 (set_special_var): New function: handle setting of special variables.
1449 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1450 (do_variable_definition): Call it.
1451 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1452 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1453 * main.c (main): Create the .RECIPEPREFIX special variable.
1454 * read.c (eval): Remove the cmd_prefix characters from the command
1455 scripts here, so they're not stored in the commands array at all,
1456 rather than waiting and stripping them out during command construction.
1457 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1459 2007-08-15 Paul Smith <psmith@gnu.org>
1461 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1462 file has had the section info removed, so add some to make.texi
1463 before we include it.
1465 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1467 * remake.c (check_dep): Reset the target state for intermediate
1468 files. They might have been considered before but not updated
1469 then (order-only for example) but they will be this time.
1470 Fixes Savannah bug #'s 3330 and 15919.
1472 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1474 Fix Savannah bug #20549:
1475 * function.c (func_shell): Call construct_command_argv with zero
1477 * job.c (construct_command_argv_internal): New argument FLAGS; all
1479 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1481 * job.h (construct_command_argv_internal): Update prototype.
1483 2007-07-13 Paul Smith <psmith@gnu.org>
1485 * file.c (expand_deps): Use variable_buffer as the start of the
1486 buffer, not the original pointer (in case it was reallocated).
1487 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1488 Fixes Savannah bug #20452.
1490 2007-07-04 Paul Smith <psmith@gnu.org>
1492 * (ALL FILES): Update to GPLv3.
1493 * (ALL FILES): Update copyright for 2007.
1495 * main.c (print_version): Move the host type info to the second line.
1497 2007-06-29 Thiemo Seufer <ths@mips.com>
1499 * maintMakefile: Update Translation Project location.
1501 2007-06-13 Paul Smith <psmith@gnu.org>
1503 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1504 "Expansion of a deferred"
1505 Fixes Savannah bug #20018.
1507 * expand.c (variable_expand_for_file): Preserve the value of
1508 reading_file rather than setting it to 0 at the end.
1509 Fixes Savannah bug #20033.
1511 2007-05-11 Paul Smith <psmith@gnu.org>
1513 * job.c (new_job): Add debug info to specify where make found the
1514 command script it is running to build a target.
1515 Fixes Savannah bug #18617.
1517 * default.c (default_suffixes,default_suffix_rules,default_variables):
1518 Add support for Objective C. Fixes Savannah bug #16389.
1519 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1521 * function.c (func_lastword): Initialize p.
1523 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1524 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1525 Dave Korn <dave.korn@artimi.com>
1527 2007-05-08 Paul Smith <psmith@gnu.org>
1529 Fix Savannah bug #19656:
1531 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1533 * make.h: Change all case-insensitive string compares to use
1534 strcasecmp() (from POSIX). If we don't have that but do have one
1535 of the others, define strcasecmp to be one of those instead. If
1536 we don't have any, declare a prototype for our own version.
1538 * misc.c (strcasecmp): Use this if we can't find any native
1539 case-insensitive string comparison function.
1540 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1541 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1543 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1544 strcasecmp() instead of stricmp().
1545 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1546 instead of strcmpi().
1547 * acinclude.m4: Remove the strcasecmp() check from here.
1549 2007-03-21 Paul Smith <psmith@gnu.org>
1551 * configure.in: Don't turn on case-insensitive file system support
1552 if --disable-... is given. Fixes Savannah bug #19348.
1554 2007-03-19 Paul Smith <psmith@gnu.org>
1556 * ALL: Use the strcache for all file name strings, or other
1557 strings which we will never free. The goal is to save memory by
1558 avoiding duplicate copies of strings. However, at the moment this
1559 doesn't save much memory in most situations: due to secondary
1560 expansion we actually save prerequisite lists twice (once before
1561 the secondary expansion, and then again after it's been parsed
1562 into individual file names in the dep list). We will resolve this
1563 in a future change, by doing the parsing up-front for targets
1564 where secondary expansion is not set.
1566 Moving things into the strcache also allows us to use const
1567 pointers in many more places.
1569 2007-01-03 Paul Smith <psmith@gnu.org>
1571 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1572 the function, not just the first. Fixes Savannah bug #18680.
1574 2006-11-18 Paul Smith <psmith@gnu.org>
1576 * strcache.c (strcache_add_len): Don't allocate a new buffer
1577 unless the string is not already nil-terminated. Technically this
1578 is a violation of the standard, since we may be passed an array
1579 that is not long enough to test one past. However, in make this
1580 is never true since we only use nil-terminated strings or
1581 sub-strings thereof.
1583 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1585 * main.c: New global cmd_prefix, defaults to '\t'.

1589 * dir.c: Constified.
1590 (dir_contents_file_exists_p): Check for an error return from
1591 readdir(), just in case.

1595 * expand.c: Constified.
1596 * function.c: Partial constification.
1597 * variable.c: Partial constification.
1598 * vmsify.c: Constification. Hard to test this but I hope I didn't
1600 * vpath.c: Partial constification.
1601 * w32/pathstuff.c: Partial constification.
1603 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1605 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1606 backslashes and drive letters as absolute.
1608 2006-10-22 Paul Smith <psmith@gnu.org>
1610 * main.c (struct command_switch): Use const and void*.
1612 2006-10-21 Paul Smith <psmith@gnu.org>
1615 * arscan.c: Constified.
1617 2006-09-30 Paul Smith <psmith@gnu.org>
1619 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1620 point to lastword since the example was updated.
1621 Fixes Savannah bug #16304.
1622 (Secondary Expansion): Correct example description.
1623 Fixes Savannah bug #16468.
1624 (Makefile Contents): Clarify that comments cannot appear within
1625 variable references or function calls.
1626 Fixes Savannah bug #16577.
1627 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1628 Fixes Savannah bug #17701.
1629 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
1630 (Prerequisite Types): Added an example of using order-only
1631 prerequisites. Fixes Savannah bug #17880.
1632 (Rule Syntax): "lise" -> "list"
1633 (Multiple Rules): ... -> @dots{}
1634 (Splitting Lines): ditto.
1636 * remake.c (update_file_1): Prereqs that don't exist should be
1637 considered changed, for the purposes of $?.
1638 Fixes Savannah bug #16051.
1640 * make.1: Remove extraneous "+".
1641 Fixes Savannah bug #16652.
1643 2006-09-06 Paul D. Smith <psmith@gnu.org>
1645 * configure.in: Include sys/types.h when checking for sys/wait.h.

1649 * configure.in (PATH_SEPARATOR_CHAR): Define to the value of
1652 * make.h (PATH_SEPARATOR_CHAR): Define only if still undefined.
1653 Normally, it is defined in config.h.
1655 * config/dospaths.m4 <ac_cv_dos_paths>: Define to yes on Cygwin as
1658 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
1659 sh_chars_sh for Windows platforms that emulate Unix.

1673 * README.cvs: Add a reminder to notify the GNU translation robot.
1675 * doc/make.texi: Change @direcategory (requested by Karl Berry).
1677 2006-04-20 Paul D. Smith <psmith@gnu.org>
1679 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1680 that don't have extended grep.
1681 (cvsclean): Use $(PERL) instead of perl.
1683 2006-04-09 Paul D. Smith <psmith@gnu.org>
1685 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1687 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1688 inner-scope variables don't mask outer-scope variables.
1690 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:
1691 * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
1692 * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
1693 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1694 values from memory allocation functions: they return void* and so
1695 don't need to be cast. Also remove (char *) casts of arguments to
1698 * configure.in: Remove checks for memcpy/memmove/strchr.
1700 * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.

1706 * variable.c, vpath.c: Ditto.
1708 * make.h (EXIT_FAILURE): Should be 1, not 0.
1710 2006-04-06 Paul D. Smith <psmith@gnu.org>
1712 * configure.in: Removed AM_C_PROTOTYPES. Starting now on we
1713 require an ISO C 1989 standard compiler and runtime library.
1715 * Makefile.am: Remove the ansi2knr feature.
1717 * make.h: Remove the PARAMS() macro definition and all uses of it.
1719 * amiga.h, ar.c, arscan.c: Remove all uses of the PARAMS() macro.

1723 * rule.c, rule.h, variable.h, vmsdir.h, vmsjobs.c, vpath.c: Ditto.
1727 2006-04-01 Paul D. Smith <psmith@gnu.org>
1729 Version 3.81 released.
1731 * NEWS: Updated for 3.81.
1733 * README.cvs: Mention that vpath builds are not supported out of
1734 CVS. Fixes Savannah bug #16236.
1735 Remove update of make.texi from the list of things to do; we use
1738 2006-03-26 Paul D. Smith <psmith@gnu.org>
1740 * doc/make.texi: Clean up licensing. Use @copying and version.texi
1741 support from automake, as described in the Texinfo manual.
1743 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1745 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1746 with lastslash, since the latter points to filename, not to
1748 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
1749 Declare and define sh_chars_sh[].
1751 2006-03-23 Paul D. Smith <psmith@gnu.org>
1753 * configure.in: Look for build.sh.in in $srcdir so it will be
1754 built for remote configurations as well.
1756 * Makefile.am: Make sure to clean up build.sh during distclean.
1757 Fixes Savannah bug #16166.
1759 * misc.c (log_access): Takes a const char *.
1760 * function.c (fold_newlines): Takes an unsigned int *.
1761 Both fixes for Savannah bug #16170.
1763 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1765 * implicit.c (pattern_search): Call set_file_variables only
1766 if we have prerequisites that need second expansion. Fixes
1767 Savannah bug #16140.
1769 2006-03-19 Paul D. Smith <psmith@gnu.org>
1771 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1772 memory on hosts that don't support it directly.
1774 * README.cvs: Add information on steps for making a release (to
1775 make sure I don't forget any).
1777 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1779 (die): Cleanup code was removed from here; call the new function.
1780 (main): If we are re-execing, clean up the jobserver first so we
1781 don't leak file descriptors.
1782 Reported by Craig Fithian <craig.fithian@citigroup.com>
1784 2006-03-17 Paul D. Smith <psmith@gnu.org>
1786 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1787 allow multiple concurrent runs.
1788 Patch from Joseph Myers <joseph@codesourcery.com>
1790 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1792 * dep.h (struct dep): Add the stem field.
1793 * misc.c (alloc_dep, free_dep): New functions.
1794 (copy_dep_chain): Copy stem.
1795 (free_dep_chain): Use free_dep.
1796 * read.c (record_files): Store stem in the dependency line.
1797 * file.c (expand_deps): Use stem stored in the dependency line. Use
1798 free_dep_chain instead of free_ns_chain.
1799 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1800 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1801 * main.c (main, handle_non_switch_argument): Ditto.
1802 * remake.c (check_dep): Ditto.
1803 * rule.c (convert_suffix_rule, freerule): Ditto.
1805 2006-03-14 Paul D. Smith <psmith@gnu.org>
1807 * expand.c (variable_append): Instead of appending everything then
1808 expanding the result, we expand (or not, if it's simple) each part
1810 (allocated_variable_append): Don't expand the final result.
1811 Fixes Savannah bug #15913.
1813 2006-03-09 Paul Smith <psmith@gnu.org>
1815 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1816 listed non-existent files as changed. Turns out there's a bug in
1817 the Linux kernel builds which means that this change causes
1818 everything to rebuild every time. We will re-introduce this fix
1819 in the next release, to give them time to fix their build system.
1820 Fixes Savannah bug #16002.
1821 Introduces Savannah bug #16051.
1823 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
1824 we *don't* find UNIX "/".

1830 locator function find_and_set_default_shell if SHELL came from the
1833 2006-02-20 Paul D. Smith <psmith@gnu.org>
1835 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1836 to be null; don't core in that case.
1838 2006-02-19 Paul D. Smith <psmith@gnu.org>
1840 * commands.c (set_file_variables): Realloc, not malloc, the static
1841 string values to avoid memory leaks.
1843 * expand.c (recursively_expand_for_file): Only set reading_file to
1844 an initialized value.
1846 * implicit.c (pattern_search): We need to make a copy of the stem
1847 if we get it from an intermediate dep, since those get freed.
1849 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1851 (enter_file) [VMS]: Ditto.
1852 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1854 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1856 * job.c (construct_command_argv_internal): Fix last change.
1858 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1859 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1860 the calls to _beginthreadex.
1862 * expand.c (recursively_expand_for_file): Initialize `save' to
1863 prevent compiler warnings.
1865 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1867 * job.c (construct_command_argv_internal): Don't create a temporary
1868 script/batch file if we are under -n. Call _setmode to switch the
1869 script file stream to text mode.
1871 2006-02-17 Paul D. Smith <psmith@gnu.org>
1873 * variable.c (merge_variable_set_lists): Don't try to merge the
1874 global_setlist. Not only is this useless, but it can lead to
1875 circularities in the linked list, if global_setlist->next in one
1876 list gets set to point to another list which also ends in
1878 Fixes Savannah bug #15757.
1880 2006-02-15 Paul D. Smith <psmith@gnu.org>
1882 Fix for Savannah bug #106.
1884 * expand.c (expanding_var): Keep track of which variable we're
1885 expanding. If no variable is being expanded, it's the same as
1887 * make.h (expanding_var): Declare it.
1888 * expand.c (recursively_expand_for_file): Set expanding_var to the
1889 current variable we're expanding, unless there's no file info in
1890 it (could happen if it comes from the command line or a default
1891 variable). Restore it before we exit.
1892 * expand.c (variable_expand_string): Use the expanding_var file
1893 info instead of the reading_file info.
1894 * function.c (check_numeric): Ditto.
1896 (func_wordlist): Ditto.
1897 (func_error): Ditto.
1898 (expand_builtin_function): Ditto.
1899 (handle_function): Ditto.
1901 2006-02-14 Paul D. Smith <psmith@gnu.org>
1903 * read.c (eval): Even if the included filenames expands to the
1904 empty string we still need to free the allocated buffer.
1906 * implicit.c (pattern_search): If we allocated a variable set for
1907 an impossible file, free it.
1908 * variable.c (free_variable_set): New function.
1909 * variable.h: Declare it.
1911 * read.c (read_all_makefiles): Makefile names are kept in the
1912 strcache, so there's never any need to alloc/free them.
1915 * main.c (main): Add "archives" to the .FEATURES variable if
1916 archive support is enabled.
1917 * doc/make.texi (Special Variables): Document it.
1919 2006-02-13 Paul D. Smith <psmith@gnu.org>
1921 * implicit.c (pattern_search): Add checking for DOS pathnames to
1922 the pattern rule target LASTSLASH manipulation.

1927 * (ALL FILES): Updated copyright and license notices.
1929 2006-02-10 Paul D. Smith <psmith@gnu.org>
1931 A new internal capability: the string cache is a read-only cache
1932 of strings, with a hash table interface for fast lookup. Nothing
1933 in the cache will ever be freed, so there's no need for reference
1934 counting, etc. This is the beginning of a full solution for
1935 Savannah bug #15182, but for now we only store makefile names here.
1937 * strcache.c: New file. Implement a read-only string cache.
1938 * make.h: Add prototypes for new functions.
1939 * main.c (initialize_global_hash_tables): Initialize the string cache.
1940 (print_data_base): Print string cache stats.
1941 * read.c (eval_makefile): Use the string cache to store makefile
1942 names. Rewrite the string allocation to be sure we free everything.
1944 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1946 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1947 directory time stamp didn't change, except on FAT filesystems.
1948 Suggested by J. David Bryan <jdbryan@acm.org>.
1950 2006-02-09 Paul D. Smith <psmith@gnu.org>
1952 * function.c (func_or): Implement a short-circuiting OR function.
1953 (func_and): Implement a short-circuiting AND function.
1954 (function_table_init): Update the table with the new functions.
1955 * doc/make.texi (Conditional Functions): Changed the "if" section
1956 to one on general conditional functions. Added documentation for
1957 $(and ...) and $(or ...) functions.
1958 * NEWS: Note new $(and ...) and $(or ...) functions.

1963 * job.c (new_job): Cache dontcare flag.
1964 * job.c (reap_children): Use cached dontcare flag instead of the
1965 one in struct file. Fixes Savannah bug #15641.
1967 2006-02-06 Paul D. Smith <psmith@gnu.org>
1969 * vpath.c (selective_vpath_search): If the file we find has a
1970 timestamp from -o or -W, use that instead of the real time.
1971 * remake.c (f_mtime): If the mtime is a special token from -o or
1972 -W, don't overwrite it with the real mtime.
1973 Fixes Savannah bug #15341.
1975 Updates from Markus Mauhart <qwe123@chello.at>:
1977 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
1978 (process_signal, process_last_err, process_exit_code): Manage
1979 invalid handle values.
1980 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
1981 manage invalid handles; remove them.
1982 * job.c (start_job_command) [WINDOWS32]: Jump out on error.
1983 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
1984 * README.cvs: Updates for building from CVS.
1986 2006-02-05 Paul D. Smith <psmith@gnu.org>
1988 * file.c (enter_file): Keep track of the last double_colon entry,
1989 to avoid walking the list every time we want to add a new one.
1990 Fixes Savannah bug #15533.
1991 * filedef.h (struct file): Add a new LAST pointer.
1993 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
1994 the comparison. For 64-bits systems the result of the subtraction
1995 might not fit into an int. Use comparison instead.
1996 Fixes Savannah bug #15534.
1998 * doc/make.texi: Update the chapter on writing commands to reflect
1999 the changes made in 3.81 for backslash/newline and SHELL handling.
2001 2006-02-01 Paul D. Smith <psmith@gnu.org>
2003 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
2004 variable st is not used when it's not initialized.
2005 Patch from Eli Zaretskii <eliz@gnu.org>.
2007 2006-01-31 Paul D. Smith <psmith@gnu.org>

2016 * main.c: Update the copyright year in the version output.
2017 * prepare_w32.bat: Remove this file from the distribution.
2019 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2021 * remake.c (update_goal_chain): Set g->changed instead of
2022 incrementing it, as it is only 8-bit wide, and could overflow if
2023 many commands got started in update_file.
2025 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
2027 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
2028 MAXIMUM_WAIT_OBJECTS.

2037 are already more children than sub_proc.c can handle, behave as if
2038 the load were too high.

2042 2006-01-14 Eli Zaretskii <eliz@gnu.org>
2044 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
2045 the shell is not sh.exe.
2047 * job.c (create_batch_file): Renamed from create_batch_filename;
2048 all callers changed. Don't close the temporary file; return its
2049 file descriptor instead. New arg FD allows to return the file
2051 (construct_command_argv_internal): Use _fdopen instead of fopen to
2052 open the batch file.
2054 2006-01-04 Paul D. Smith <psmith@gnu.org>
2056 * readme.vms: Updates for case-insensitive VMS file systems from

2077 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2078 disable warnings for MSC.
2079 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2081 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2083 * doc/make.texi (Execution): Add a footnote about changes in
2084 handling of backslash-newline sequences. Mention the differences
2085 on MS-DOS and MS-Windows.
2087 * NEWS: More details about building the MinGW port and a pointer
2088 to README.W32. Fix the section name that describes the new
2089 backward-incompatible processing of backslash-newline sequences.
2090 The special processing of SHELL set to "cmd" is only relevant to
2091 MS-Windows, not MS-DOS.
2093 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2095 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2096 to DWORD, to avoid compiler warnings.
2097 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2098 use %ld in format, to avoid compiler warnings.
2100 * doc/make.texi (Special Targets): Fix a typo.
2101 (Appending): Fix cross-reference to Setting.
2102 (Special Variables, Secondary Expansion, File Name Functions)
2103 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2104 periods after a sentence.
2105 (Execution): Add @: after "e.g.".
2106 (Environment): Fix punctuation.
2107 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2108 (Shell Function, Target-specific): Add @: after "vs."
2110 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2112 * read.c (record_target_var): Initialize variable's export field
2113 with v_default instead of leaving it "initialized" by whatever
2114 garbage happened to be on the heap.
2116 2005-12-12 Paul D. Smith <psmith@gnu.org>
2118 * make.1: Fix some display errors and document all existing options.
2119 Patch by Mike Frysinger <vapier@gentoo.org>.
2121 2005-12-11 Paul D. Smith <psmith@gnu.org>
2123 * implicit.c (pattern_search): If 2nd expansion is not set for
2124 this implicit rule, replace the pattern with the stem directly,
2125 and don't re-expand the variable list. Along with the other
2126 .SECONDEXPANSION changes below, fixes bug #13781.
2128 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2130 * implicit.c (pattern_search): Mark other files that this rule
2131 builds as targets so that they are not treated as intermediates
2132 by the pattern rule search algorithm. Fixes bug #13022.
2134 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2136 * remake.c (notice_finished_file): Propagate the change of
2137 modification time to all the double-colon entries only if
2138 it is the last one to be updated. Fixes bug #14334.
2140 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2142 * function.c (func_flavor): Implement the flavor function which
2143 returns the flavor of a variable.
2144 * doc/make.texi (Functions for Transforming Text): Document it.
2145 * NEWS: Add it to the list of new functions.
2147 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2149 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2151 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2152 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2154 2005-10-26 Paul Smith <psmith@gnu.org>
2156 * read.c (record_files): Don't set deps flags if there are no deps.
2157 * maintMakefile: We only need to build the templates when we are
2158 creating a distribution, so don't do it for "all".
2160 2005-10-24 Paul D. Smith <psmith@gnu.org>
2162 Make secondary expansion optional: its enabled by declaring the
2163 special target .SECONDEXPANSION.
2165 * NEWS: Update information on second expansion capabilities.
2166 * doc/make.texi (Secondary Expansion): Document the
2167 .SECONDEXPANSION special target and its behavior.
2168 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2169 prerequisite list was found in a static pattern rule.
2170 (free_dep_chain): Declare a prototype.
2171 * file.c (parse_prereqs): New function: break out some complexity
2173 (expand_deps): If we aren't doing second expansion, replace % with
2174 the stem for static pattern rules. Call the new function.
2175 * filedef.h (parse_prereqs): Declare a prototype.
2176 * implicit.c (pattern_search): Initialize the new staticpattern
2178 * main.c (second_expansion): Declare a global variable to remember
2179 if the special target has been seen. Initialize the new
2180 staticpattern field for prerequisites.
2181 * make.h: Extern for second_expansion.
2182 * misc.c (free_dep_chain): New function: frees a struct dep list.
2183 * read.c (read_all_makefiles): Initialize the staticpattern field.
2184 (eval_makefile): Ditto.
2185 (record_files): Check for the .SECONDEXPANSION target and set
2186 second_expansion global if it's found.
2187 Use the new free_dep_chain() instead of doing it by hand.
2188 Set the staticpattern field for prereqs of static pattern targets.
2190 2005-10-16 Paul D. Smith <psmith@gnu.org>
2192 * main.c (main): Set CURDIR to be a file variable instead of a
2193 default, so that values of CURDIR inherited from the environment
2194 won't override the make value.
2196 2005-09-26 Paul D. Smith <psmith@gnu.org>
2198 * job.c (construct_command_argv_internal): If the line is empty
2199 remember to free the temporary argv strings.
2202 2005-09-16 Paul D. Smith <psmith@gnu.org>
2204 * job.c (start_job_command): The noerror flag is a boolean (single
2205 bit); set it appropriately.
2206 Reported by Mark Eichin <eichin@metacarta.com>
2208 2005-08-29 Paul D. Smith <psmith@gnu.org>
2210 * function.c (func_error): On Windows, output from $(info ...)
2211 seems to come in the wrong order. Try to force it with fflush().
2213 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2215 * read.c (record_files): Move code that sets stem for static
2216 pattern rules out of the if (!two_colon) condition so it is
2217 also executed for two-colon rules. Fixes Savannah bug #13881.
2219 2005-08-08 Paul D. Smith <psmith@gnu.org>
2221 * make.h: Don't test that __STDC__ is non-0. Some compilers
2222 (Windows for example) set it to 0 to denote "ISO C + extensions".
2225 2005-08-07 Paul D. Smith <psmith@gnu.org>
2227 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2228 conditional (slightly different version of a fix from Eli).
2230 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2231 If make is running in parallel without -k and two jobs die in a
2232 row, but not too close to each other, then make will quit without
2233 waiting for the rest of the jobs to die.
2235 * main.c (die): Don't reset err before calling reap_children() the
2236 second time: we still want it to be in the error condition.
2237 * job.c (reap_children): Use a static variable, rather than err,
2238 to control whether or not the error message should be printed.
2240 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2242 * w32/subproc/sub_proc.c: Include signal.h.
2243 (process_pipe_io, process_file_io): Pass a pointer to a local
2244 DWORD variable to GetExitCodeProcess. If the exit code is
2245 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2247 * job.c [WINDOWS32]: Include windows.h.
2248 (main_thread) [WINDOWS32]: New global variable.
2249 (reap_children) [WINDOWS32]: Get the handle for the main thread
2250 and store it in main_thread.
2252 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2253 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2254 doing anything else. When we are done, close the main thread
2255 handle and exit with status 130.
2257 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2259 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2262 * main.c (find_and_set_default_shell): If found a DOSish shell,
2263 set sh_found and the value of default_shell, and report the
2264 findings in debug mode.
2266 * job.c (construct_command_argv_internal): Check unixy_shell, not
2267 no_default_sh_exe, to decide whether to use Unixy or DOSish
2270 * README.W32: Update with info about the MinGW build.
2272 * build_w32.bat: Support MinGW.
2274 * w32/subproc/build.bat: Likewise.
2276 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2277 printing DWORD args.
2279 * function.c (windows32_openpipe): Fix format strings for printing
2282 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2284 (start_job_command): Fix format string for printing the result of
2286 (start_job_command) [WINDOWS32]: Do not define.
2287 (exec_command): Fix format string for printing HANDLE args.
2289 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2290 to avoid compiler warnings.
2291 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2292 (Note: some of these fixes were submitted independently by J. Grant)
2294 2005-07-30 J. Grant <jg@jguk.org>
2296 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2297 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2298 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2300 2005-07-15 Paul Smith <psmith@gnu.org>
2302 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2303 we don't have a POSIX shell, then revert to the old
2304 backslash-newline behavior (where they are stripped).
2307 2005-07-08 Paul D. Smith <psmith@gnu.org>
2309 * config.h.W32.template: Reorder to match the standard config.h,
2310 for easier comparisons.
2311 From J. Grant <jg@jguk.org>
2313 * maintMakefile: Remove .dep_segment before overwriting it, in
2314 case it's not writable or noclobber is set.
2315 * expand.c (variable_expand_string): Cast result of pointer
2316 arithmetic to avoid a warning.
2317 * main.c (switches): Add full-fledged final initializer.
2319 2005-07-06 Paul D. Smith <psmith@gnu.org>
2321 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2322 * signame.c (strsignal): If we found _sys_siglist[] or
2323 __sys_siglist[] use those instead of sys_siglist[].
2324 From Albert Chin <china@thewrittenword.com>
2326 2005-07-04 Paul D. Smith <psmith@gnu.org>
2328 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2329 globfree(); set up to use the GNU versions.
2330 From Martin Zinser <zinser@zinser.no-ip.info>
2332 2005-07-03 Paul D. Smith <psmith@gnu.org>
2334 From J. Grant <jg@jguk.org>:
2336 * README.W32.template: Update the Windows and tested MSVC versions.
2337 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2338 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2339 * build_w32.bat: Ditto.
2340 * w32/subproc/build.bat: Ditto.
2342 2005-06-28 Paul D. Smith <psmith@gnu.org>
2344 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2345 declaration was checked but not present.
2347 2005-06-27 Paul D. Smith <psmith@gnu.org>
2349 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2350 to unsigned long. Fixes Savannah bug #13550.
2352 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2353 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2354 Fixes Savannah bug #13551.
2356 2005-06-26 Paul D. Smith <psmith@gnu.org>
2358 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2359 it if ANSI_STRING is not set.
2361 2005-06-25 Paul D. Smith <psmith@gnu.org>
2363 * read.c (eval): If no filenames are passed to any of the
2364 "include" variants, don't print an error.
2365 * doc/make.texi (Include): Document this.
2366 Fixes Savannah bug #1761.
2368 * job.c (construct_command_argv_internal): Sanitize handling of
2369 backslash/newline pairs according to POSIX: that is, keep the
2370 backslash-newline in the command script, but remove a following
2371 TAB character, if present. In the fast path, make sure that the
2372 behavior matches what the shell would do both inside and outside
2373 of quotes. In the slow path, quote the backslash and put a
2374 literal newline in the string.
2375 Fixes Savannah bug #1332.
2376 * doc/make.texi (Execution): Document the new behavior and give
2378 * NEWS: Make a note of the new behavior.
2380 * make.h [WINDOWS32]: #include <direct.h>.
2381 Fixes Savannah bug #13478.
2383 * remake.c (name_mtime): If the stat() of a file fails and the -L
2384 option was given and the file is a symlink, take the best mtime of
2385 the symlink we can get as the mtime of the file and don't fail.
2386 Fixes Savannah bug #13280.
2388 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2389 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2390 inside a variable reference. Make this function static as it's
2392 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2393 parsing an unexpanded line looking for semicolons.
2394 Fixes Savannah bug #1454.
2395 * misc.c (remove_comments): Move this to read.c and make it static
2396 as it's only used there. Call find_char_unquote() with new arg.
2397 * make.h: Remove prototypes for find_char_unquote() and
2398 remove_comments() since they're static now.
2400 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2401 its export flag and obtain its value. When we need to re-exec,
2402 increment the value and add it into the environment.
2403 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2404 * NEWS: Mention MAKE_RESTARTS.
2405 * main.c (always_make_set): New variable. Change the -B option to
2406 set this one instead.
2407 (main): When checking makefiles, only set always_make_flag if
2408 always_make_set is set AND the restarts flag is 0. When building
2409 normal targets, set it IFF always_make_set is set.
2410 (main): Avoid infinite recursion with -W, too: only set what-if
2411 files to NEW before we check makefiles if we've never restarted
2412 before. If we have restarted, set what-if files to NEW _after_ we
2414 Fixes Savannah bug #7566:
2416 2005-06-17 Paul D. Smith <psmith@gnu.org>
2418 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2419 in the prerequisites list.
2421 2005-06-12 Paul D. Smith <psmith@gnu.org>
2423 Fix Savannah bug # 1328.
2425 * configure.in: Check for atexit().
2426 * misc.c (close_stdout): Test stdout to see if writes to it have
2427 failed. If so, be sure to exit with a non-0 error code. Based on
2428 code found in gnulib.
2429 * make.h: Prototype.
2430 * main.c (main): Install close_stdout() with atexit().
2432 2005-06-10 Paul D. Smith <psmith@gnu.org>
2434 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2436 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2437 headers; make vmsWaitForChildren() static; extern vmsify().
2438 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2439 Don't create child_execute_job() here (it's in vmsjobs.c).
2440 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2442 2005-06-09 Paul D. Smith <psmith@gnu.org>
2444 * variable.c (push_new_variable_scope): File variables point
2445 directly to the global_setlist variable. So, inserting a new
2446 scope in front of that has no effect on those variables: they
2447 don't go through current_variable_set_list. If we're pushing a
2448 scope and the current scope is global, push it "the other way" so
2449 that the new setlist is in the global_setlist variable, and
2450 next points to a new setlist with the global variable set.
2451 (pop_variable_scope): Properly undo a push with the new
2453 Fixes Savannah bug #11913.
2455 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2457 * job.c (reap_children): Don't die of the command failed but
2458 the dontcare flag is set. Fixes Savannah bug #13216.
2460 * implicit.c (pattern_search): When creating a target from
2461 an implicit rule match, lookup pattern target and set precious
2462 flag in a newly created target. Fixes Savannah bug #13218.
2464 2005-05-13 Paul D. Smith <psmith@gnu.org>
2466 Implement "if... else if... endif" syntax.
2468 * read.c (eval): Push all checks for conditional words ("ifeq",
2469 "else", etc.) down into the conditional_line() function.
2470 (conditional_line): Rework to allow "else if..." clause. New
2471 return value -2 for lines which are not conditionals. The
2472 ignoring flag can now also be 2, which means "already parsed a
2473 true branch". If that value is seen no other branch of this
2474 conditional can be considered true. In the else parsing if there
2475 is extra text after the else, invoke conditional_line()
2476 recursively to see if it's another conditional. If not, it's an
2477 error. If so, raise the conditional value to this level instead
2478 of creating a new conditional nesting level. Special check for
2479 "else" and "endif", which aren't allowed on the "else" line.
2480 * doc/make.texi (Conditional Syntax): Document the new syntax.
2482 2005-05-09 Paul D. Smith <psmith@gnu.org>
2484 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2485 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2486 recurses to the w32 directory, even on non-Windows systems. Use
2487 the method suggested in the automake manual.
2488 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2489 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2491 2005-05-07 Paul D. Smith <psmith@gnu.org>
2493 * main.c (die): If we're dying with a fatal error (not that a
2494 command has failed), write back any leftover tokens before we go.
2496 * job.c (set_child_handler_action_flags): If there are jobs
2497 waiting for the load to go down, set an alarm to go off in 1
2498 second. This allows us to wake up from a potentially long-lasting
2499 read() and start a new job if the load has gone down. Turn it off
2501 (job_noop): Dummy signal handler function.
2502 (new_job): Invoke it with the new semantics.
2504 * docs/make.texi: Document secondary expansion. Various cleanups
2507 2005-05-03 Paul D. Smith <psmith@gnu.org>
2509 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2510 the targets which are to ultimately be made are called "goals";
2511 see the GNU make manual. Also, MAKECMDGOALS, etc.
2513 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2514 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2515 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2517 2005-05-02 Paul D. Smith <psmith@gnu.org>
2519 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2520 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2521 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2522 functions to vmsjobs.c. #include it into jobs.c.
2524 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2525 jobserver tokens. I found that this happens when an exported
2526 recursive variable contains a $(shell ...) function reference: in
2527 this situation we could "forget" to write back a token.
2529 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2530 we have. It's not reliable to depend on the number of children in
2531 our linked list so keep a separate count.
2532 (new_job): Check jobserver_tokens rather than children &&
2533 waiting_jobs. Increment jobserver_tokens when we get one.
2534 (free_child): If jobserver_tokens is 0, internal error. If it's
2535 >1, write a token back to the jobserver pipe (we don't write a
2536 token for the "free" job). Decrement jobserver_tokens.
2538 * main.c: Add variable master_job_slots.
2539 (main): Set it to hold the number of jobs requested if we're the
2540 master process, when using the jobserver.
2541 (die): Sanity checks: first test jobserver_tokens to make sure
2542 this process isn't holding any tokens we didn't write back.
2543 Second, if master_job_slots is set count the tokens left in the
2544 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2546 2005-04-24 Paul D. Smith <psmith@gnu.org>
2548 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2549 with -l# can lose jobserver tokens, because waiting jobs are not
2550 consulted properly when checking for the "free" token.
2552 * job.c (free_child): Count waiting_jobs as having tokens.
2553 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2554 handle jobs waiting for the load to drop.
2556 2005-04-23 Paul D. Smith <psmith@gnu.org>
2558 * main.c (main): Be careful to not core if a variable setting in
2559 the environment doesn't contain an '='. This is illegal but can
2560 happen in broken setups.
2561 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2563 2005-04-12 Paul D. Smith <psmith@gnu.org>
2565 The second expansion feature causes significant slowdown. Timing
2566 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2567 read the makefile before the feature, to 11+s to do the same
2568 operations after the feature. Additionally, memory usage
2569 increased drastically. To fix this I added some intelligence that
2570 avoids the overhead of the second expansion unless it's required.
2572 * dep.h: Add a new boolean field, need_2nd_expansion.
2574 * read.c (eval): When creating the struct dep for the target,
2575 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2576 (record_files): If there's a "%" in a static pattern rule, it gets
2577 converted to "$*" so set need_2nd_expansion to 1.
2579 * file.c (expand_deps): Rework to be more efficient. Only perform
2580 initialize_file_variables(), set_file_variables(), and
2581 variable_expand_for_file() if the need_2nd_expansion is set.
2583 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2584 (pattern_search): Ditto.
2585 * main.c (handle_non_switch_argument): Ditto.
2587 * read.c (read_all_makefiles): Ditto.
2588 (eval_makefile): Ditto.
2590 2005-04-07 Paul D. Smith <psmith@gnu.org>
2592 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2593 * variable.c (sync_Path_environment): Ditto.
2594 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2596 * main.c (main): Define the .FEATURES variable.
2597 * NEWS: Announce .FEATURES.
2598 * doc/make.texi (Special Variables): Document .FEATURES.
2600 * remake.c (check_dep): If a file is .PHONY, update it even if
2601 it's marked intermediate. Fixes Savannah bug #12331.
2603 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2605 * file.c (expand_deps): Factor out the second expansion and
2606 prerequisite line parsing logic from snap_deps().
2608 * file.c (snap_deps): Use expand_deps(). Expand and parse
2609 prerequisites of the .SUFFIXES special target first. Fixes
2610 Savannah bug #12320.
2612 2005-03-13 Paul D. Smith <psmith@gnu.org>
2614 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2617 2005-03-11 Paul D. Smith <psmith@gnu.org>
2619 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2620 available, not undefined (from Earnie Boyd).
2622 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2624 * implicit.c (pattern_search): Mark an intermediate target as
2625 precious if it happened to be a prerequisite of some (other)
2626 target. Fixes Savannah bug #12267.
2628 2005-03-09 Paul D. Smith <psmith@gnu.org>
2630 * read.c (eval_makefile): Add alloca(0).
2631 (eval_buffer): Ditto.
2633 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2635 * main.c (main): Use o_file instead of o_default when defining
2636 the .DEFAULT_TARGET special variable.
2637 * read.c (eval): Use define_variable_global() instead of
2638 define_variable() when setting new value for the .DEFAULT_TARGET
2639 special variable. Fixes Savannah bug #12266.
2641 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2643 * imlicit.c (pattern_search): Mark files for which an implicit
2644 rule has been found as targets. Fixes Savannah bug #12202.
2646 2005-03-04 Paul D. Smith <psmith@gnu.org>
2649 * doc/make.texi (Automatic Variables): Document $|.
2651 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2653 * read.c (record_files): Instead of substituting % with
2654 actual stem value in dependency list replace it with $*.
2655 This fixes stem triple expansion bug.
2657 * implicit.c (pattern_search): Copy stem to a separate
2658 buffer and make it a properly terminated string. Assign
2659 this buffer instead of STEM (which is not terminated) to
2660 f->stem. Instead of substituting % with actual stem value
2661 in dependency list replace it with $*. This fixes stem
2662 triple expansion bug.
2664 2005-03-01 Paul D. Smith <psmith@gnu.org>
2666 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2667 on Windows, as it takes a handle not a pid. Just exit.
2668 Fix from patch #3679, provided by Alessandro Vesely.
2670 * configure.in: Update check for sys_siglist[] from autoconf manual.
2671 * signame.c (strsignal): Update to use the new autoconf macro.
2673 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2675 * read.c (record_files): Add a check for the list of prerequisites
2676 of a static pattern rule being empty. Fixes Savannah bug #12180.
2678 2005-02-28 Paul D. Smith <psmith@gnu.org>
2680 * doc/make.texi (Text Functions): Update docs to allow the end
2681 ordinal for $(wordlist ...) to be 0.
2682 * function.c (func_wordlist): Fail if the start ordinal for
2683 $(wordlist ...) is <1. Matches documentation.
2684 Resolves Savannah support request #103195.
2686 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2687 previously we were stopping when !-q, exactly the opposite. This
2688 has been wrong since version 1.34, in 1994!
2689 (update_file): If we got an error don't break out to run more
2690 double-colon rules: just return immediately.
2691 Fixes Savannah bug #7144.
2693 2005-02-27 Paul D. Smith <psmith@gnu.org>
2695 * misc.c (end_of_token): Make argument const.
2696 * make.h: Update prototype.
2698 * function.c (abspath, func_realpath, func_abspath): Use
2699 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2700 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2701 * read.c (record_files): Ditto.
2702 * variable.c (do_variable_definition): Ditto.
2704 * function.c (func_error): Create a new function $(info ...) that
2705 simply prints the message to stdout with no extras.
2706 (function_table_init): Add new function to the table.
2707 * NEWS: Add $(info ...) reference.
2708 * doc/make.texi (Make Control Functions): Document it.
2710 New feature: if the system supports symbolic links, and the user
2711 provides the -L/--check-symlink-time flag, then use the latest
2712 mtime between the symlink(s) and the target file.
2714 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2715 readlink(). If both are available, define MAKE_SYMLINKS.
2716 * main.c: New variable: check_symlink_flag.
2717 (usage): Add a line for -L/--check-symlink-times to the help string.
2718 (switches): Add -L/--check-symlink-times command line argument.
2719 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2720 print a warning and disable it again.
2721 * make.h: Declare check_symlink_flag.
2722 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2723 if the file is a symlink then check each link in the chain and
2724 choose the NEWEST mtime we find as the mtime for the file. The
2725 newest mtime might be the file itself!
2726 * NEWS: Add information about this new feature.
2727 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2729 Avoid core dumps described in Savannah bug # 12124:
2731 * file.c: New variable snapped_deps remember whether we've run
2733 (snap_deps): Set it.
2734 * filedef.h: Extern it.
2735 * read.c (record_files): Check snapped_deps; if it's set then
2736 we're trying to eval a new target/prerequisite relationship from
2737 within a command script, which we don't support. Fatal.
2739 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2741 Implementation of the .DEFAULT_TARGET special variable.
2743 * read.c (eval): If necessary, update default_target_name when
2745 * read.c (record_files): Update default_target_file if
2746 default_target_name has changed.
2747 * main.c (default_target_name): Define.
2748 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2749 default_target_name is set use default_target_file as a root
2751 * filedef.h (default_target_name): Declare.
2752 * dep.h (free_dep_chain):
2753 * misc.c (free_dep_chain): Change to operate on struct nameseq
2754 and change name to free_ns_chain.
2755 * file.c (snap_deps): Update to use free_ns_chain.
2757 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2759 Implementation of the second expansion in explicit rules,
2760 static pattern rules and implicit rules.
2762 * read.c (eval): Refrain from chopping up rule's dependencies.
2763 Store them in a struct dep as a single dependency line. Remove
2764 the code that implements SySV-style automatic variables.
2766 * read.c (record_files): Adjust the code that handles static
2767 pattern rules to expand all percents instead of only the first
2768 one. Reverse the order in which dependencies are stored so that
2769 when the second expansion reverses them again they appear in
2770 the makefile order (with some exceptions, see comments in
2771 the code). Remove the code that implements SySV-style automatic
2774 * file.c (snap_deps): Implement the second expansion and chopping
2775 of dependency lines for explicit rules.
2777 * implicit.c (struct idep): Define an auxiliary data type to hold
2778 implicit rule's dependencies after stem substitution and
2781 * implicit.c (free_idep_chain): Implement.
2783 * implicit.c (get_next_word): Implement helper function for
2784 parsing implicit rule's dependency lines into words taking
2785 into account variable expansion requests. Used in the stem
2788 * implicit.c (pattern_search): Implement the second expansion
2789 for implicit rules. Also fixes bug #12091.
2791 * commands.h (set_file_variables): Declare.
2792 * commands.c (set_file_variables): Remove static specifier.
2794 * dep.h (free_dep_chain): Declare.
2795 * misc.c (free_dep_chain): Implement.
2797 * variable.h (variable_expand_for_file): Declare.
2798 * expand.c (variable_expand_for_file): Remove static specifier.
2800 * make.h (strip_whitespace): Declare.
2801 * function.c (strip_whitespace): Remove static specifier.
2803 2005-02-26 Paul D. Smith <psmith@gnu.org>
2805 * main.c (main): Check for ferror() when reading makefiles from stdin.
2806 Apparently some shells in Windows don't close pipes properly and
2809 2005-02-24 Jonathan Grant <jg@jguk.org>
2811 * configure.in: Add MinGW configuration options, and extra w32 code
2813 * Makefile.am: Add MinGW configuration options, and extra w32 code
2815 * main.c: Determine correct program string (after last \ without .exe).
2816 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2818 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2819 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2820 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2821 environment support.
2823 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2825 * function.c (func_shell): When initializing error_prefix, check
2826 that reading file name is not null. This fixes long-standing
2827 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2829 2005-02-09 Paul D. Smith <psmith@gnu.org>
2831 * maintMakefile: Update the CVS download URL to simplify them.
2832 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2833 downloading the .texi files from Savannah now.
2835 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2837 * main.c (handle_non_switch_argument): Only add variables to
2838 command_variables if they're not already there: duplicate settings
2839 waste space and can be confusing to read.
2841 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2842 this header is never included by non-WINDOWS32 code, and it
2843 requires <config.h> to define which isn't always included first.
2845 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2846 testing MINGW32 versions.
2848 * main.c (log_working_directory): flush stdout to be sure the WD
2849 change is printed before any stderr messages show up.
2851 2005-02-01 Paul D. Smith <psmith@gnu.org>
2853 * maintMakefile (po_repo): Update the GNU translation site URL.
2855 2004-12-01 Paul D. Smith <psmith@gnu.org>
2857 * main.c (main): Change char* env_shell to struct variable shell_var.
2858 * variable.c (target_environment): Use new shell_var.
2860 2004-11-30 Paul D. Smith <psmith@gnu.org>
2862 * configure.in: The old way we avoided creating build.sh from
2863 build.sh.in before build.sh.in exists doesn't work anymore; we
2864 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2865 the help!). This also keeps automake from complaining.
2866 * Makefile.am (README): Add a dummy target so automake won't
2867 complain that this file doesn't exist when we checkout from CVS.
2868 * maintMakefile (.dep_segment): Rewrite this rule since newer
2869 versions of automake don't provide DEP_FILES.
2871 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2873 Implementation of `realpath' and `abspath' built-in functions.
2875 * configure.in: Check for realpath.
2876 * function.c (abspath): Return an absolute file name that does
2877 not contain any `.' or `..' components, nor repeated `/'.
2878 * function.c (func_abspath): For each name call abspath.
2879 * function.c (func_realpath): For each name call realpath
2880 from libc or delegate to abspath if realpath is not available.
2881 * doc/make.texi (Functions for File Names): Document new functions.
2882 * doc/make.texi (Quick Reference): Ditto.
2884 2004-11-28 Paul D. Smith <psmith@gnu.org>
2886 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2887 arguments. Fixes bug #10252.
2889 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2891 * main.c (main): Set SHELL to v_noexport by default. Remember the
2892 original environment setting of SHELL in the env_shell variable.
2893 * main.h: Export new env_shell variable.
2894 * variable.c (target_environment): If we find a v_noexport
2895 variable for SHELL, add a SHELL variable with the env_shell value.
2896 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2897 * doc/make.texi (Variables/Recursion): Ditto.
2899 2004-11-28 Paul D. Smith <psmith@gnu.org>
2901 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2902 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2903 Patch by Alessandro Vesely.
2905 2004-11-12 Paul D. Smith <psmith@gnu.org>
2907 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2908 the command line if it's inside a string.
2909 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2911 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2913 * function.c (func_lastword): New function: return last word
2914 from the list of words.
2915 * doc/make.texi: Document $(lastword ). Fix broken links in
2916 Quick Reference section.
2918 2004-10-06 Paul D. Smith <psmith@gnu.org>
2920 Apply patch from Alessandro Vesely, provided with bug # 9748.
2921 Fix use of tmpnam() to work with Borland C.
2923 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2924 construction of a temporary filename, and call new function
2925 create_batch_filename().
2926 (create_batch_filename) [WINDOWS32]: New function to create a
2929 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2931 * read.c (record_target_var): Expand simple pattern-specific
2933 * variable.c (initialize_file_variables): Do not expand simple
2934 pattern-specific variable.
2936 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2938 * remake.c (update_file_1): When rebuilding makefiles inherit
2939 dontcare flag from a target that triggered update.
2941 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2943 * variable.c (initialize_file_variables): Mark pattern-specific
2944 variable as a per-target and copy export status.
2946 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2948 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2950 * implicit.c (pattern_search): When considering an implicit rule's
2951 prerequisite check that it is actually a target rather then
2952 just an entry in the file hashtable.
2954 2004-09-21 Paul D. Smith <psmith@gnu.org>
2956 * read.c (readstring): Fix some logic errors in backslash handling.
2957 (eval): Remove some unnecessary processing in buffer handling.
2958 (record_target_var): Assert that parse_variable_definition() succeeded.
2959 Reported by: Markus Mauhart <qwe123@chello.at>.
2961 * misc.c: Removed the sindex() function. All instances of this
2962 function were trivially replaceable by the standard strstr()
2963 function, and that function will always have better (or certainly
2964 no worse) performance than the very simple-minded algorithm
2965 sindex() used. This can matter with complex makefiles.
2966 * make.h: Remove the prototype for sindex().
2967 * function.c (subst_expand): Convert sindex() call to strstr().
2968 This means we no longer need to track the TLEN value so remove that.
2969 (func_findstring): Convert sindex() to strstr().
2970 * commands.c (chop_commands): Convert sindex() calls to strstr().
2971 Suggested by: Markus Mauhart <qwe123@chello.at>.
2973 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2974 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2975 If SHELL is set to CMD.EXE then assume it's batch-mode and
2976 non-unixy. I wrote the code differently from the patch, though,
2977 to make it safer. This also resolves bug #9174.
2979 2004-09-20 Paul D. Smith <psmith@gnu.org>
2981 * expand.c (variable_expand_string): Modify to invoke
2982 patsubst_expand() instead of subst_expand(); the latter didn't
2983 handle suffix patterns correctly.
2984 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
2985 was used only from variable_expand_string() and is no longer used
2987 (func_subst): Ditto, on call to subst_expand().
2988 (patsubst_expand): Require the percent pointers to point to the
2989 character after the %, not to the % itself.
2990 * read.c (record_files): New call criteria for patsubst_expand().
2991 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
2992 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2994 2004-09-19 Paul D. Smith <psmith@gnu.org>
2996 * function.c (subst_expand): Fix a check in by_word: look for a
2997 previous blank if we're beyond the beginning of the string, not
2998 the beginning of the word.
2999 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3001 2004-05-16 Paul D. Smith <psmith@gnu.org>
3003 * remake.c (update_goal_chain): Change the argument specifying
3004 whether we're rebuilding makefiles to be a global variable,
3005 REBUILDING_MAKEFILES.
3006 (complain): Extract the code that complains about no rules to make
3007 a target into a separate function.
3008 (update_file_1): If we tried to rebuild a file during the makefile
3009 rebuild phase and it was dontcare, then no message was printed.
3010 If we then try to build the same file during the normal build,
3011 print a message this time.
3012 (remake_file): Don't complain about un-remake-able files when
3013 we're rebuilding makefiles.
3015 2004-05-11 Paul D. Smith <psmith@gnu.org>
3017 * job.c (construct_command_argv_internal): OS/2 patches from
3018 Andreas Buening <andreas.buening@nexgo.de>.
3020 2004-05-10 Paul D. Smith <psmith@gnu.org>
3022 * remake.c (update_file): Don't walk the double-colon chain unless
3023 this is a double-colon rule. Fix suggested by Boris Kolpackov
3024 <boris@kolpackov.net>.
3026 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3027 * readme.vms: New section describing OpenVMS support and issues.
3028 * default.c (default_variables): Add support for IA64.
3029 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3030 without some privilege aborts make with the error
3031 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3032 pressing Ctrl+Y and the input device is no terminal. The change
3033 catches this error and just continues.
3035 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3037 2004-04-25 Paul D. Smith <psmith@gnu.org>
3039 * commands.c (set_file_variables): Set $< properly in the face of
3040 order-only prerequisites.
3041 Patch from Boris Kolpackov <boris@kolpackov.net>
3043 2004-04-21 Bob Byrnes <byrnes@curl.com>
3045 * main.c (main): Notice failures to remake makefiles.
3047 2004-03-28 Paul D. Smith <psmith@gnu.org>
3049 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3051 * job.c: No default shell for RISC OS.
3052 (load_too_high): Hard-code the return to 1.
3053 (construct_command_argv_internal): No sh_chars or sh_cmds.
3054 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3056 2004-03-20 Paul D. Smith <psmith@gnu.org>
3058 * variable.c (do_variable_definition): Don't append from the
3059 global set if a previous non-appending target-specific variable
3060 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3063 * expand.c (reference_variable): Don't give up on variables with
3064 no value that have the target-specific append flag set: they might
3065 have a value after all. Reported by Oliver Schmidt
3066 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3067 <nikulin@dx1cmd.inp.nsk.su>.
3069 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3070 refer to absolute pathnames in directories that don't exist: some
3071 portion of the makefile could create those directories before we
3072 match the pattern. Fixes bugs #775 and #108.
3074 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3076 * main.c (main): Free makefile_mtimes if we have any.
3077 * README.W32.template: Update documentation for the current status
3078 of the MS-Windows port.
3079 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3080 environment variable is sometimes already defined which causes the
3082 * main.c (debug_signal_handler): Only define this function if
3083 SIGUSR1 is available.
3085 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3087 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3088 * README.OS2.template: Documentation updates.
3089 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3090 link line for safety.
3091 * maintMakefile (build.sh.in): Remove an extraneous ")".
3092 * job.c (child_execute_job): Close saved FDs.
3093 * job.c (exec_command) [OS/2]: exec_command(): If the command
3094 can't be exec'ed and if the shell is not Unix-sh, then try again
3095 with argv = { "cmd", "/c", ... }. Normally, this code is never
3096 reached for the cmd shell unless the command really doesn't exist.
3097 (construct_command_argv_internal) [OS/2]: The code for cmd
3098 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3099 The CMD builtin commands are case insensitive so use strcasecmp().
3101 2004-03-19 Paul D. Smith <psmith@gnu.org>
3103 * read.c (do_define): Re-order line counter increment so the count
3104 is accurate (we were losing one line per define). Reported by
3105 Dave Yost <Dave@Yost.com>.
3107 2004-03-06 Paul D. Smith <psmith@gnu.org>
3109 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3111 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3112 * misc.c (message,error,fatal): Ditto.
3113 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3114 * config.h.W32.template: Ditto.
3115 * config.h-vms.template: Ditto.
3116 * config.ami.template: Ditto.
3118 2004-03-04 Paul D. Smith <psmith@gnu.org>
3120 * README.template: Add a note about broken /bin/sh on SunOS
3121 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3123 * misc.c (message, error, fatal): Don't use "..." if we're using
3124 varargs. ansi2knr should handle this but it doesn't work: it
3125 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3126 done. On many systems (SunOS for example) va_dcl is a #define.
3127 So, force the use of the non-"..." version on pre-ANSI compilers.
3129 * maintMakefile (sign-dist): Create some rules to help automate
3130 the new GNU ftp upload method.
3132 2004-02-24 Paul D. Smith <psmith@gnu.org>
3134 * config.h.W32.template: Add HAVE_STDARG_H
3135 * config.h-vms.template: Ditto.
3136 * config.ami.template: Ditto.
3138 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3140 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3141 * build_w32.bat: Remove extra "+".
3143 2004-02-23 Paul D. Smith <psmith@gnu.org>
3145 * make.h: Create an UNUSED macro to mark unused parameters.
3146 * (many): Clean up warnings by applying UNUSED, fixing
3147 signed/unsigned incompatibilities, etc.
3149 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3151 * filedef.h: Name the command_state enumeration.
3152 * file.c (set_command_state): Use the enumeration in the function
3155 * configure.in: Explicitly set SET_MAKE to empty, to disable
3156 MAKE=make even when no make already exists. Fix bug #3823.
3158 2004-02-22 Paul D. Smith <psmith@gnu.org>
3160 * maintMakefile: Perl script to clean up all non-CVS files. Use
3161 it on all the subdirectories for the cvs-clean target.
3163 * main.c (decode_switches): Require non-empty strings for all our
3164 string command-line options. Fixes Debian bug # 164165.
3166 * configure.in: Check for stdarg.h and varargs.h.
3167 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3168 for printing messages.
3169 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3174 A number of patches for OS/2 support from Andreas Buening
3175 <andreas.buening@nexgo.de>:
3177 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3178 disable the SIGCHLD handler.
3179 (reap_children) [OS/2]: Remove special handling of job_rfd.
3180 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3181 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3182 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3183 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3184 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3187 2004-02-21 Paul D. Smith <psmith@gnu.org>
3189 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3190 <mail@kristov.de> reports that if process_begin() fails we don't
3191 handle the error condition correctly in all cases.
3192 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3193 to have a newline on the message.
3195 * job.c (construct_command_argv_internal): Add "test" to UNIX
3196 sh_cmds[]. Fixes Savannah bug # 7606.
3198 2004-02-04 Paul D. Smith <psmith@gnu.org>
3200 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3201 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3202 Hartmut Becker <Hartmut.Becker@hp.com>.
3204 2004-01-21 Paul D. Smith <psmith@gnu.org>
3206 * job.c (load_too_high): Implement an algorithm to control the
3207 "thundering herd" problem when using -l to control job creation
3208 via the load average. The system only recomputes the load once a
3209 second but we can start many jobs in a second. To solve this we
3210 keep track of the number of jobs started in the last second and
3211 apply a weight to try to guess what a correct load would be.
3212 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3213 Also fixes bug #4693.
3214 (reap_children): Decrease the job count for this second.
3215 (start_job_command): Increase the job count for this second.
3217 * read.c (conditional_line): Expand the text after ifn?def before
3218 checking to see if it's a single word. Fixes bug #7257.
3220 2004-01-09 Paul D. Smith <psmith@gnu.org>
3222 * file.c (print_file): Recurse to print all targets in
3223 double-colon rules. Fixes bug #4518, reported (with patch) by
3224 Andrew Chatham <chatham@google.com>.
3226 2004-01-07 Paul D. Smith <psmith@gnu.org>
3228 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3229 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3230 AC_FUNC_SETVBUF_REVERSED.
3232 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3233 (MAKE Variable): Fix Savannah bug #4898.
3235 * job.c (construct_command_argv_internal): Add "!" to the list of
3236 shell escape chars. POSIX sh allows it to appear before a
3237 command, to negate the exit code. Fixes bug #6404.
3239 * implicit.c (pattern_search): When matching an implicit rule,
3240 remember which dependencies have the ignore_mtime flag set.
3241 Original fix provided in Savannah patch #2349, by Benoit
3242 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3244 2003-11-22 Paul D. Smith <psmith@gnu.org>
3246 * README.W32.template (Outputs): Clarification on -j with
3247 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3250 2003-11-02 Paul D. Smith <psmith@gnu.org>
3252 * function.c (func_if): Strip all the trailing whitespace from the
3253 condition, then don't expand it. Fixed bug # 5798.
3255 * expand.c (recursively_expand_for_file): If we're expanding a
3256 variable with no file context, then use the variable's context.
3259 2003-10-21 Paul D. Smith <psmith@gnu.org>
3261 * main.c (log_working_directory): Add newlines to printf()s.
3263 * README.cvs: Add a note to ignore warnings during autoreconf.
3265 * maintMakefile (po_repo): Set a new URL for PO file updates.
3266 (get-config/config.guess get-config/config.sub): Get these files
3267 from the Savannah config project instead of ftp.gnu.org.
3269 2003-10-05 Paul Eggert <eggert@twinsun.com>
3271 * main.c (main): Avoid potential subscript error if environ has
3274 2003-08-22 Paul D. Smith <psmith@gnu.org>
3276 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3277 systems which don't yet implement the C89 standard :-/.
3279 2003-07-18 Paul D. Smith <psmith@gnu.org>
3281 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3282 [WINDOWS32]: Initialize hash.
3284 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3286 * dir.c (read_dirstream): Provide a workaround for broken versions of
3287 the MinGW dirent structure.
3289 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3291 * w32/include/dirent.h: Add __MINGW32__ filter.
3293 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3295 * make.h: Add global declaration of *make_host.
3296 * main.c (print_usage): Remove local declaration of *make_host.
3297 (print_version): Display "This program built for ..." after Copyright
3300 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3302 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3303 execution of "makeinfo --html make.texi".
3305 2003-04-30 Paul D. Smith <psmith@gnu.org>
3307 * build.template: Make some changes to maybe allow this script to
3308 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3310 * README.OS2.template: New file for OS/2 support. Original
3311 contributed by Andreas Buening.
3312 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3315 2003-04-19 Paul D. Smith <psmith@gnu.org>
3317 Fix bug #1405: allow a target to match multiple pattern-specific
3320 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3321 variable.c, where they've always belonged.
3322 * rule.h: Move the prototypes and struct pattern_var as well.
3323 * variable.c (initialize_file_variables): Invoke
3324 lookup_pattern_var() in a loop, until no more matches are found.
3325 If a match is found, create a new variable set for the target's
3326 pattern variables. Then merge the contents of each matching
3327 pattern variable set into the target's pattern variable set.
3328 (lookup_pattern_var): Change this function to be usable
3329 in a loop. It takes a starting position: if NULL, start at the
3330 beginning; if non-NULL, start with the pattern variable after that
3331 position, and return the next matching pattern.
3332 (create_pattern_var): Create a unique instance of
3333 pattern-specific variables for every definition in the makefile.
3334 Don't combine the same pattern together. This allows us to
3335 process the variable handling properly even when the same pattern
3336 is used multiple times.
3337 (parse_variable_definition): New function: break out the parsing
3338 of a variable definition line from try_variable_definition.
3339 (try_variable_definition): Call parse_variable_definition to
3341 (print_variable_data_base): Print out pattern-specific variables.
3342 * variable.h (struct variable): Remember when a variable is
3343 conditional. Also remember its flavor.
3344 (struct pattern_var): Instead of keeping a variable set, we just
3345 keep a single variable for each pattern.
3346 * read.c (record_target_var): Each pattern variable contains only a
3347 single variable, not a set, so create it properly.
3348 * doc/make.texi (Pattern-specific): Document the new behavior.
3350 2003-04-17 Paul D. Smith <psmith@gnu.org>
3352 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3353 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3354 file/directory naming rules for VMS so I can't tell whether this
3357 2003-04-09 Paul D. Smith <psmith@gnu.org>
3359 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3360 DOS-style pathnames: backslash separators and drive specifiers.
3362 2003-03-28 Paul D. Smith <psmith@gnu.org>
3364 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3365 the intermediate flag on all targets. Fixes bug #2515.
3367 2003-03-24 Paul D. Smith <psmith@gnu.org>
3369 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3370 Upgrade to autoconf 2.57 and automake 1.7.3.
3372 * job.c: More OS/2 changes from Andreas Buening.
3374 * file.c (print_file): Fix variable initialization.
3377 * remake.c (notice_finished_file):
3379 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3380 some calls (like readdir()) return NULL in valid situations
3381 without resetting errno. Fixes bug #2846.
3383 2003-02-25 Paul D. Smith <psmith@gnu.org>
3385 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3387 * job.c (_is_unixy_shell) [OS/2]: New function.
3388 Set default shell to /bin/sh.
3389 (reap_children): Close the job_rfd pipe here since we don't use a
3391 (set_child_handler_action_flags): define this to empty on OS/2.
3392 (start_job_command): Close the jobserver pipe and use
3393 child_execute_job() instead of fork/exec.
3394 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3395 rather than exec'ing, then reconfigure stdin/stdout.
3396 (exec_command): Rewrite to use spawn instead of exec. Return the
3399 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3400 in DOS. Handle the TEMP environment variable as in DOS. Don't
3401 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3402 use -j in DOS mode. Use child_execute_job() instead of
3405 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3408 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3409 prototypes that return values.
3411 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3413 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3414 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3416 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3419 2003-02-24 Paul D. Smith <psmith@gnu.org>
3421 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3422 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3423 (child_execute_job) [VMS]: Handle error status properly.
3424 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3426 * function.c (func_shell): Use EINTRLOOP() while reading from the
3427 subshell pipe (Fixes bug #2502).
3428 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3430 * main.c (main): Ditto.
3432 2003-01-30 Paul D. Smith <psmith@gnu.org>
3434 * read.c (eval): eval() was not fully reentrant, because the
3435 collapsed buffer was static. Change it to be an automatic
3436 variable so that eval() can be invoked recursively.
3438 (eval): Apply patch # 1022: fix memory reference error on long
3439 target-specific variable lines.
3440 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3442 * function.c (check_numeric): Combine the is_numeric() function
3443 into this function, since it's only called from one place.
3444 Constify this function. Have it print the incorrect string in the
3445 error message. Fixes bug #2407.
3446 (strip_whitespace): Constify.
3447 (func_if): Constify.
3448 * expand.c (expand_argument): Constify.
3450 2003-01-29 Paul D. Smith <psmith@gnu.org>
3452 Fix bug # 2169, also reported by other people on various systems.
3454 * make.h: Some systems, such as Solaris and PTX, do not fully
3455 implement POSIX-compliant SA_RESTART functionality; important
3456 system calls like stat() and readdir() can still fail with EINTR
3457 even if SA_RESTART has been set on the signal handler. So,
3458 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3459 EINTR for system calls which return -1 or 0 (NULL), respectively,
3461 Also, remove the old atomic_stat()/atomic_readdir() and
3462 HAVE_BROKEN_RESTART handling.
3464 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3466 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3467 * remake.c (touch_file): Ditto.
3469 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3470 * read.c (construct_include_path): Ditto.
3471 * remake.c (name_mtime): Ditto.
3472 * vpath.c (selective_vpath_search): Ditto.
3473 * dir.c (find_directory): Ditto.
3474 (local_stat): Ditto.
3475 (find_directory): Use ENULLLOOP() to wrap opendir().
3476 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3478 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3479 atomic_readdir() handling.
3481 2003-01-22 Paul D. Smith <psmith@gnu.org>
3483 * function.c (func_call): Fix Bug #1744. If we're inside a
3484 recursive invocation of $(call ...), mask any of the outer
3485 invocation's arguments that aren't used by this one, so that this
3486 invocation doesn't "inherit" them accidentally.
3488 2002-12-05 Paul D. Smith <psmith@gnu.org>
3490 * function.c (subst_expand): Valery Khamenia reported a
3491 pathological performance hit when doing substitutions on very
3492 large values with lots of words: turns out we were invoking
3493 strlen() a ridiculous number of times. Instead of having each
3494 call to sindex() call strlen() again, keep track of how much of
3495 the text we've seen and pass the length to sindex().
3497 2002-11-19 Paul D. Smith <psmith@gnu.org>
3499 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3502 2002-11-16 Paul D. Smith <psmith@gnu.org>
3504 * NMakefile.template (OBJS): Add hash.c object file.
3505 * SMakefile.template (srcs): Ditto.
3506 * Makefile.ami (objs): Ditto.
3507 * build_w32.bat: Ditto.
3509 * Makefile.DOS.template: Remove extra dependencies.
3511 2002-10-25 Paul D. Smith <psmith@gnu.org>
3513 * expand.c (install_variable_buffer): New function. Install a new
3514 variable_buffer context and return the previous one.
3515 (restore_variable_buffer): New function. Free the current
3516 variable_buffer context and put a previously saved one back.
3517 * variable.h: Prototypes for {install,restore}_variable_buffer.
3518 * function.c (func_eval): Push a new variable_buffer context
3519 before we eval, then restore the old one when we're done.
3522 * read.c (install_conditionals): New function. Install a new
3523 conditional context and return the previous one.
3524 (restore_conditionals): New function. Free the current
3525 conditional context and put a previously saved one back.
3526 (eval): Use the {install,restore}_conditionals for "include"
3528 (eval_buffer): Use {install,restore}_conditionals to preserve the
3529 present conditional state before we evaluate the buffer.
3532 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3534 (Recursion): Add a variable index entry for CURDIR.
3536 * README.cvs: Update to appropriate versions.
3537 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3538 don't need to copy loadavg.c: automake is smart enough to create
3539 it for me. Still have a bug in automake related to ansi2knr tho.
3541 2002-10-14 Paul D. Smith <psmith@gnu.org>
3543 * remake.c (notice_finished_file): Only touch targets if they have
3544 at least one command (as per POSIX). Resolve Bug #1418.
3546 * *.c: Convert to using ANSI C-style function definitions.
3547 * Makefile.am: Enable the ansi2knr feature of automake.
3548 * configure.in: ditto.
3550 2002-10-13 Paul D. Smith <psmith@gnu.org>
3552 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3553 for automatic variable values like $^, etc. In the case of very
3554 large lists of prerequisites this causes problems. Instead reuse
3555 a static buffer (resizeable) for each variable.
3557 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3558 target-specific variable definitions. Check for it and set an
3560 (record_target_var): Set the export field to v_export if the
3561 "exported" flag is set.
3562 * doc/make.texi (Target-specific): Document the ability to use
3565 * doc/make.texi: Change the name of the section on automatic
3566 variables from "Automatic" to "Automatic Variables". Added text
3567 clarifying the scope of automatic variables.
3569 2002-10-04 Paul D. Smith <psmith@gnu.org>
3571 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3573 (record_files): Ditto.
3575 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3576 the search for the '=' to only within the enclosing parens.
3578 2002-10-03 Paul D. Smith <psmith@gnu.org>
3580 Version 3.80 released.
3582 * dir.c: Change hash functions to use K&R function definition style.
3583 * function.c: Ditto.
3585 * variable.c: Ditto.
3587 Update to automake 1.7.
3589 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3590 (pdf): Remove this target as automake now provides one.
3592 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3594 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3596 * makefile.com: Updates for GNU make 3.80.
3597 * makefile.vms: Ditto.
3599 2002-09-23 Paul D. Smith <psmith@gnu.org>
3601 * read.c (enum make_word_type): Remove w_comment.
3602 (get_next_mword): Don't treat comment characters as special; where
3603 this function is used we will never see a comment (it's stripped
3604 before we get here) and treating comments specially means that
3605 targets like "foo\#bar" aren't handled properly.
3607 2002-09-18 Paul D. Smith <psmith@gnu.org>
3609 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3611 * read.c (eval): Expansion of arguments to export/unexport was
3612 ignoring all arguments after the first one. Change the algorithm
3613 to expand the whole line once, then parse the results.
3615 2002-09-17 Paul D. Smith <psmith@gnu.org>
3617 Fix Bug #940 (plus another bug I found while looking at this):
3619 * read.c (record_target_var): enter_file() will add a new entry if
3620 it's a double-colon target: we don't want to do that in this
3621 situation. Invoke lookup_file() and only enter_file() if it does
3622 not already exist. If the file we get back is a double-colon then
3623 add this variable to the "root" double-colon target.
3625 * variable.c (initialize_file_variables): If this file is a
3626 double-colon target but is not the "root" target, then initialize
3627 the root and make the root's variable list the parent of our
3630 2002-09-13 Paul D. Smith <psmith@gnu.org>
3632 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3634 * hash.c (round_up_2): Get rid of a warning.
3636 2002-09-12 Paul D. Smith <psmith@gnu.org>
3638 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3639 so it doesn't complain about getloadavg.c.
3641 * commands.c (set_file_variables): Make sure we always alloca() at
3642 least 1 character for the value of $? (for '\0').
3644 2002-09-11 Paul D. Smith <psmith@gnu.org>
3646 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3647 macro to use RESULT instead of the incorrect _RESULT_.
3649 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3650 and atomic_readdir(). We need to #include dirent.h to get this to
3652 * misc.c (atomic_readdir): Fix typos.
3654 2002-09-10 Paul D. Smith <psmith@gnu.org>
3656 * read.c (eval): Expand variable lists given to export and
3657 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3658 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3660 * doc/make.texi (Variables/Recursion): Document this.
3661 (Conditional Syntax): And here.
3663 2002-09-09 Paul D. Smith <psmith@gnu.org>
3665 * configure.in: Check for memmove().
3667 2002-09-07 Paul D. Smith <psmith@gnu.org>
3669 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3670 Michael Sterrett <msterret@coat.com> reports that while it has
3671 SA_RESTART, it does not work properly.
3673 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3674 that invokes stat() and loops to do it again if it returns EINTR.
3675 (atomic_readdir): Ditto, with readdir().
3677 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3678 and readdir() to atomic_stat() and atomic_readdir().
3680 2002-09-04 Paul D. Smith <psmith@gnu.org>
3682 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3683 reports that GNU make sometimes doesn't recognize that targets can
3684 be made, when directories can be created as prerequisites. He
3685 reports that changing the order of predicates in the DEP->changed
3686 flag test so that lookup_file() is always performed, solves this
3689 2002-08-08 Paul D. Smith <psmith@gnu.org>
3691 * configure.in: Require a newer version of gettext.
3693 * misc.c (perror_with_name): Translate the format string (for
3694 right-to-left language support).
3695 (pfatal_with_name): Ditto.
3697 * main.c: Create a static array of strings to store the usage
3698 text. This is done to facilitate translations.

3700 (switches): Remove values for obsolete fields.
3701 (print_usage): Print each element of the usage array.
3703 * hash.c: Change function definitions to be K&R style.
3705 2002-08-02 Paul D. Smith <psmith@gnu.org>
3707 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3708 this one because it's too hard to get right. We'll look at it for
3710 * main.c (main): Don't create the .TARGETS variable.
3711 * variable.c (handle_special_var): Don't handle .TARGETS.
3713 2002-08-01 Paul D. Smith <psmith@gnu.org>
3715 * main.c (switches): Add a new option, -B (--always-make). If

3717 if they don't appear to be out of date.
3718 (always_make_flag): New flag.
3719 * make.h: Extern always_make_flag.
3720 * remake.c (update_file_1): Check always_make_flag; if it's set we
3721 will always rebuild any target we can, even if none of its
3722 prerequisites are newer.
3725 * doc/make.texi (Shell Function): Make it clear that make
3726 variables marked as "export" are not passed to instances of the
3729 Add new introspection variable .VARIABLES and .TARGETS.
3731 * variable.c (handle_special_var): New function. If the variable
3732 reference passed in is "special" (.VARIABLES or .TARGETS),
3733 calculate the new value if necessary. .VARIABLES is handled here:
3734 walk through the hash of defined variables and construct a value
3735 which is a list of the names. .TARGETS is handled by
3736 build_target_list().
3737 (lookup_variable): Invoke handle_special_var().
3738 * file.c (build_target_list): Walk through the hask of known files
3739 and construct a list of the names of all the ones marked as
3741 * main.c (main): Initialize them to empty (and as simple variables).
3742 * doc/make.texi (Special Variables): Document them.
3743 * NEWS: Mention them.
3745 * variable.h (struct variable): Add a new flag "exportable" which
3746 is true if the variable name is valid for export.
3747 * variable.c (define_variable_in_set): Set "exportable" when a new
3748 variable is defined.
3749 (target_environment): Use the "exportable" flag instead of
3750 re-checking the name here... an efficiency improvement.
3752 2002-07-31 Paul D. Smith <psmith@gnu.org>
3754 * config.h-vms.template: Updates to build on VMS. Thanks to
3755 Brian_Benning@aksteel.com for helping verify the build.
3756 * makefile.com: Build the new hash.c file.
3757 * hash.h: Use strcpmi(), not stricmp(), in the
3758 HAVE_CASE_INSENSITIVE_FS case.
3760 2002-07-30 Paul D. Smith <psmith@gnu.org>
3762 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3763 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3764 Reported by <Brian_Benning@aksteel.com>.
3766 2002-07-10 Paul D. Smith <psmith@gnu.org>
3768 * variable.c (pop_variable_scope): Remove variable made unused by
3769 new hash infrastructure.
3770 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3771 comparisons as well as name comparisons.
3772 * variable.h: Add a prototype for new hash_init_function_table().
3773 * file.c (lookup_file): Remove variables made unused by new hash
3775 * dir.c (directory_contents_hash_2): Missing return of hash value.
3776 (dir_contents_file_exists_p): Remove variables made unused by new
3777 hash infrastructure.
3780 Installed Greg McGary's integration of the hash functions from the
3781 GNU id-utils package:
3783 2002-07-10 Greg McGary <greg@mcgary.org>
3785 * scripts/functions/filter-out: Add literals to to the
3786 pattern space in order to add complexity, and trigger
3787 use of an internal hash table. Fix documentation strings.
3788 * scripts/targets/INTERMEDIATE: Reverse order of files
3789 passed to expected `rm' command.
3791 2002-07-10 Greg McGary <greg@mcgary.org>

3885 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3886 prerequisite list. A real SysV make will expand the entire
3887 prerequisites list _twice_: we don't do that as it's a big
3888 backward-compatibility problem. We only replace those specific
3891 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3892 references left in the list of prerequisites. Check for .POSIX as
3893 we record targets, so we can disable non-POSIX behavior while
3894 reading makefiles as well as running them.
3895 (eval): Check the prerequisite list to see if we have anything
3896 that looks like a SysV prerequisite variable reference.
3898 2002-07-09 Paul D. Smith <psmith@gnu.org>
3900 * doc/make.texi (Prerequisite Types): Add a new section describing
3901 order-only prerequisites.
3903 * read.c (uniquize_deps): If we have the same file as both a
3904 normal and order-only prereq, get rid of the order-only prereq,
3905 since the normal one supersedes it.
3907 2002-07-08 Paul D. Smith <psmith@gnu.org>
3909 * AUTHORS: Added Greg McGary to the AUTHORS file.
3910 * NEWS: Blurbed order-only prerequisites.
3911 * file.c (print_file): Show order-only deps properly when printing
3914 * maintMakefile: Add "update" targets for wget'ing the latest
3915 versions of various external files. Taken from Makefile.maint in
3918 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3919 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3921 2002-07-07 Paul D. Smith <psmith@gnu.org>
3923 * po/*.po: Remove. We'll use wget to retrieve them at release
3926 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3927 rather than a shell you get an exception. Make sure we look up
3928 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3930 * remake.c (notice_finished_file): Fix handling of -t flag.
3931 Patch provided by Henning Makholm <henning@makholm.net>.
3933 * implicit.c (pattern_search): Some systems apparently run short
3934 of stack space, and using alloca() in this function caused an
3935 overrun. I modified it to use xmalloc() on the two variables
3936 which seemed like they might get large. Fixes Bug #476.
3938 * main.c (print_version): Update copyright notice to conform with
3940 (print_usage): Update help output.
3942 * function.c (func_eval): Create a new make function, $(eval
3943 ...). Expand the arguments, put them into a buffer, then invoke
3944 eval_buffer() on the resulting string.
3945 (func_quote): Create a new function, $(quote VARNAME). Inserts
3946 the value of the variable VARNAME without expanding it any
3949 * read.c (struct ebuffer): Change the linebuffer structure to an
3950 "eval buffer", which can be either a file or a buffer.
3951 (eval_makefile): Move the code in the old read_makefile() which
3952 located a makefile into here: create a struct ebuffer with that
3953 information. Have it invoke the new function eval() with that
3955 (eval_buffer): Create a new function that creates a struct ebuffer
3956 that holds a string buffer instead of a file. Have it invoke
3957 eval() with that ebuffer.
3958 (eval): New function that contains the guts of the old
3959 read_makefile() function: this function parses makefiles. Obtains
3960 data to parse from the provided ebuffer. Some modifications to
3961 make the flow of the function cleaner and clearer. Still could
3962 use some work here...
3963 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3964 contents of the define/endef variable from the ebuffer.
3965 (readstring): Read the next line from a string-style ebuffer.
3966 (readline): Read the next line from an ebuffer. If it's a string
3967 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3970 * dep.h (eval_buffer): Prototype eval_buffer();
3972 * variable.c (do_variable_definition): Make sure that all
3973 non-target-specific variables are registered in the global set.
3974 If we're invoked from an $(eval ...) we might be inside a $(call
3975 ...) or other function which has pushed a variable scope; we still
3976 want to define our variables from evaluated makefile code in the
3979 2002-07-03 Greg McGary <greg@mcgary.org>
3981 * dep.h (struct dep) [ignore_mtime]: New member.
3982 [changed]: convert to a bitfield.
3983 * implicit.c (pattern_search): Zero ignore_mtime.
3984 * main.c (main, handle_non_switch_argument): Likewise.
3985 * rule.c (convert_suffix_rule): Likewise.
3986 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
3987 (read_makefile): Parse '|' in prerequisite list.
3988 (uniquize_deps): Consider ignore_mtime when comparing deps.
3989 * remake.c (update_file_1, check_dep): Don't force remake for
3990 dependencies that have d->ignore_mtime.
3991 * commands.c (FILE_LIST_SEPARATOR): New constant.
3992 (set_file_variables): Don't include a
3993 prerequisite in $+, $^ or $? if d->ignore_mtime.
3996 2002-06-18 Paul D. Smith <psmith@gnu.org>
3998 * make.texinfo: Updates for next revision. New date/rev/etc.
3999 Recreate all Info menus. Change license on the manual to the GNU
4000 Free Documentation License. A number of typos.
4001 (Variables Simplify): Don't use "-" before it's defined.
4002 (Automatic Prerequisites): Rewrite the target example to work
4003 properly if the compile fails. Remove incorrect comments about
4004 how "set -e" behaves.
4005 (Text Functions): Move the "word", "wordlist", "words", and
4006 "firstword" functions here, from "File Name Functions".
4007 * make-stds.texi: Update from latest GNU version.
4008 * fdl.texi: (created) Import the latest GNU version.
4010 2002-06-06 Paul D. Smith <psmith@gnu.org>
4012 * variable.c (do_variable_definition): New function: extract the
4013 part of try_variable_definition() that actually sets the value
4014 into a separate function.
4015 (try_variable_definition): Call do_variable_definition() after
4016 parsing the variable definition string.
4017 (define_variable_in_set): Make the name argument const.
4019 * variable.h (enum variable_flavor): Make public.
4020 (do_variable_definition): Create prototype.
4022 * read.c (read_all_makefiles): Create a new built-in variable,
4024 (read_makefile): Add each makefile read in to this variable value.
4026 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4028 * Makefile.DOS.template: Tweak according to changes in the
4029 distribution. Add back the dependencies of *.o files.
4031 * configh.dos.template: Synchronize with config.h.in.
4033 2002-05-09 Paul D. Smith <psmith@gnu.org>
4035 * file.c (file_timestamp_now): Use K&R function declaration.
4037 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4038 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4039 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4040 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4041 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4042 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4043 nlist.n_name is a pointer rather than an array.
4045 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4046 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4047 * configure.in: Use it instead of the old version.
4049 * main.c (main): Prefer setvbuf() to setlinebuf().
4051 2002-05-08 Paul D. Smith <psmith@gnu.org>
4053 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4054 (loadavg_LDADD): Ditto.
4056 2002-04-29 Paul D. Smith <psmith@gnu.org>
4058 * expand.c (recursively_expand_for_file): Rename
4059 recursively_expand() to recursively_expand_for_file() and provide
4060 an extra argument, struct file. If the argument is provided, set
4061 the variable scope to that of the file before expanding.
4062 * variable.h (recursively_expand): Make this a macro that invokes
4063 recursively_expand_for_file() with a NULL file pointer.
4064 * variable.c (target_environment): Call the renamed function and
4065 provide the current file context.
4066 Fixes Debian bug #144306.
4068 2002-04-28 Paul D. Smith <psmith@gnu.org>
4070 Allow $(call ...) user-defined variables to be self-referencing
4071 without throwing an error. Allows implementation of transitive
4072 closures, among other possibly useful things.
4073 Requested by: Philip Guenther <guenther@sendmail.com>
4075 * variable.h (struct variable): Add a new field: exp_count, and
4076 new macros to hold its size and maximum value.
4077 (warn_undefined): Make this a macro.
4078 * variable.c (define_variable_in_set): Initialize it.
4079 * expand.c (recursively_expand): If we detect recursive expansion
4080 of a variable, check the exp_count field. If it's greater than 0
4081 allow the recursion and decrement the count.
4082 (warn_undefined): Remove this (now a macro in variable.h).
4083 * function.c (func_call): Before we expand the user-defined
4084 function, modify its exp_count field to contain the maximum
4085 number of recursive calls we'll allow. After the call, reset it
4088 2002-04-21 Paul D. Smith <psmith@gnu.org>
4090 Modified to use latest autoconf (2.53), automake (1.6.1), and
4091 gettext (0.11.1). We're using gettext's new "external" support,
4092 to avoid including libintl source with GNU make.
4094 * README.cvs: New file. Explain how to build GNU make from CVS.
4096 * configure.in: Modify checking for the system glob library.
4097 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4098 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4099 etc. will manage it correctly). Set an automake conditional
4100 USE_LOCAL_GLOB to decide whether to compile the glob library.
4102 * getloadavg.c (main): Include make.h in the "TEST" program to
4105 * Makefile.am: Remove special rules for loadavg. Replace them
4106 with Automake capabilities for building extra programs.
4108 * signame.c: This file does nothing if the system provide
4109 strsignal(). If not, it implements strsignal(). If the system
4110 doesn't define sys_siglist, then we make our own; otherwise we use
4112 * signame.h: Removed.
4114 * main.c (main): No need to invoke signame_init(). Update copyright.
4116 * ABOUT-NLS: Removed.
4117 * gettext.c: Removed.
4118 * gettext.h: Get a simplified copy from the gettext package.
4120 * i18n/*.po: Moved to po/.
4123 * config/*: Created. Contains package configuration helper files.
4124 * config.guess, config.sub: Moved to config directory.
4126 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4127 Rework to use new-style autoconf features. Use the "external"
4128 mode for gettext. Make the build.sh config file conditional on
4129 whether build.sh.in exists, to avoid autoconf errors.
4130 * acinclude.m4: Removed almost all macros as being obsolete.
4131 Rewrote remaining macros to use AC_DEFINE.
4132 * acconfig.h: Removed.
4134 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4135 conditional to handle customs support. Remove special handling
4138 2002-04-20 Paul D. Smith <psmith@gnu.org>
4140 * function.c (func_call): Don't mark the argument variables $1,
4141 etc. as recursive. They've already been fully expanded so
4142 there's no need to do it again, and doing so strips escaped $'s.
4143 Reported by Sebastian Glita <glseba@yahoo.com>.
4145 * remake.c (notice_finished_file): Walk through double-colon
4146 entries via the prev field, not the next field!
4147 Reported by Greg McGary <greg@mcgary.org>.
4149 * main.c (main): If the user specifies -q and asks for a specific
4150 target which is a makefile, we got an assert. In that case it
4151 turns out we should continue normally instead.
4153 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4155 * i18n/he.po: Installed a new translation.
4157 2002-01-07 Paul D. Smith <psmith@gnu.org>
4159 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4161 2001-12-04 Paul D. Smith <psmith@gnu.org>
4163 * i18n/ja.po: Installed an updated translation.
4165 2001-09-06 Paul Eggert <eggert@twinsun.com>
4167 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4168 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4170 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4172 (main): Get rid of any avoidable limit on stack size.
4174 2001-09-04 Paul D. Smith <psmith@gnu.org>
4176 * i18n/da.po: Installed an updated translation.
4178 2001-08-03 Paul D. Smith <psmith@gnu.org>
4180 * i18n/fr.po: Installed an updated translation.
4181 Resolves Debian bug #106720.
4183 2001-06-13 Paul D. Smith <psmith@gnu.org>
4185 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4188 2001-06-11 Paul D. Smith <psmith@gnu.org>
4190 * i18n/ko.po: Installed a new translation.
4192 2001-05-06 Paul D. Smith <psmith@gnu.org>
4194 Modify the EINTR handling.
4196 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4197 the way in which we manage the file descriptor/signal handler race
4198 trap to be more efficient.
4200 2001-05-06 Paul Eggert <eggert@twinsun.com>
4202 Restart almost all system calls that are interrupted, instead
4203 of worrying about EINTR. The lone exception is the read() for
4206 * configure.in (HAVE_SA_RESTART): New macro.
4207 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4208 * main.c (main): Use SA_RESTART instead of the old,
4209 nonstandard SA_INTERRUPT.
4211 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4212 * main.c (bsd_signal): New function or macro,
4213 if the implementation doesn't supply it.
4214 (The bsd_signal function will be in POSIX 1003.1-200x.)
4215 (HANDLESIG): Remove.
4216 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4218 * make.h (EINTR_SET): Remove.
4219 (SA_RESTART): New macro.
4221 * arscan.c (ar_member_touch): Don't worry about EINTR.
4222 * function.c (func_shell): Likewise.
4223 * job.c (reap_children, free_child, new_job): Likewise.
4224 * main.c (main): Likewise.
4225 * remake.c (touch_file, name_mtime): Likewise.
4227 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4228 if fstat failed with errno!=EINTR, the error was ignored.
4230 * job.c (set_child_handler_action_flags): New function.
4231 (new_job): Use it to temporarily clear the SIGCHLD action flags
4232 while reading the token.
4234 2001-05-02 Paul D. Smith <psmith@gnu.org>
4236 * job.c (start_job_command): Don't add define/endef per-line flags
4237 to the top-level flags setting.
4239 2001-04-03 Paul D. Smith <psmith@gnu.org>
4241 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4242 bit on error, so check for odd return values, not non-0 return
4244 (VMS_get_member_info): Calculate the timezone differences correctly.
4245 Reported by John Fowler <jfowler@nyx.net>.
4248 2001-03-14 Paul D. Smith <psmith@gnu.org>
4250 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4251 value before invoking define_variable().
4252 Reported by John Fowler <jfowler@nyx.net>.
4254 2001-02-07 Paul D. Smith <psmith@gnu.org>
4256 * read.c (record_target_var): If we reset the variable due to a
4257 command-line variable setting overriding it, turn off the "append"
4260 2001-01-17 Paul D. Smith <psmith@gnu.org>
4262 * variable.c (lookup_variable) [VMS]: When getting values from the
4263 environment, allocate enough space for the _value_ plus escapes,
4264 not enough space for the name plus escapes :-/.
4265 Reported by John Fowler <jfowler@nyx.net>.
4267 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4268 warnings that make generates, so it doesn't look like an error.
4269 Reported by Karl Berry <karl@gnu.org>.
4272 Fix for PR/2020: Rework appended target-specific variables. I'm
4273 fairly confident this algorithm is finally correct.
4275 * expand.c (allocated_variable_append): Rewrite. Instead of
4276 expanding each appended variable then adding all the expanded
4277 strings together, we append all the unexpanded values going up
4278 through the variable set contexts, then expand the final result.
4279 This behaves just like non-target-specific appended variable
4280 values, while the old way didn't in various corner cases.
4281 (variable_append): New function: recursively append the unexpanded
4282 value of a variable, walking from the outermost variable scope to
4284 * variable.c (lookup_variable): Remove the code that looked up the
4285 variable set list if the found variable was "append". We don't
4287 (lookup_variable_in_set): Make this non-static so we can use it
4289 (try_variable_definition): Use lookup_variable_in_set() rather
4290 than faking out current_variable_set_list by hand (cleanup).
4291 * variable.h: Add a prototype for the now non-static
4292 lookup_variable_in_set().
4294 2000-11-17 Paul D. Smith <psmith@gnu.org>
4296 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4297 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4298 before throwing a fit.
4300 2000-11-17 Paul D. Smith <psmith@gnu.org>
4302 * read.c (readline): CRLF calculations had a hole, if you hit the
4303 buffer grow scenario just right. Reworked the algorithm to avoid
4304 the need for len or lastlen at all. Problem description with
4305 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4307 2000-10-24 Paul D. Smith <psmith@gnu.org>
4309 * gettext.c (SWAP): Declare this with the prototype, otherwise
4310 some systems don't work (non-32-bit? Reported for Cray T3E).
4311 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4313 2000-10-05 Paul D. Smith <psmith@gnu.org>
4315 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4316 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4318 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4320 2000-09-22 Paul D. Smith <psmith@gnu.org>
4322 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4323 parts of the real gettext.h here, and we expect to really include
4324 the real gettext.h later. If we keep this #define, it's ignored.
4326 2000-09-21 Paul D. Smith <psmith@gnu.org>
4328 * main.c (log_working_directory): Rework the text to use complete
4329 sentences, to make life simpler for the translators.
4331 2000-08-29 Paul D. Smith <psmith@gnu.org>
4333 * file.c (remove_intermediates): Print a debug message before we
4334 remove intermediate files, so the user (if she uses -d) knows
4337 2000-08-21 Paul D. Smith <psmith@gnu.org>
4339 * variable.c (try_variable_definition): Change how we handle
4340 target-specific append variable defns: instead of just setting the
4341 value, expand it as an append _but_ only within the current
4342 target's context. Otherwise we lose all but the last value if the
4343 variable is appended more than once within the current target
4344 context. Fixes PR/1831.
4346 2000-08-16 Paul D. Smith <psmith@gnu.org>
4348 * function.c (func_shell): Nul-terminate the buffer before
4349 printing an exec error message (just in case it's not!).
4350 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4352 2000-07-25 Paul D. Smith <psmith@gnu.org>
4354 * job.c (construct_command_argv_internal): Add "~" to the list of
4355 sh_chars[] which disallow optimizing out the shell call.
4357 2000-07-23 Paul Eggert <eggert@twinsun.com>
4359 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4360 supersedes --disable-nsec-timestamps.
4361 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4362 * README: Remove --disable-nsec-timestamps.
4364 * filedef.h (struct file.low_resolution_time): New member.
4365 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4366 * remake.c (update_file_1):
4367 Avoid spurious rebuilds due to low resolution time stamps,
4368 generalizing the earlier code that applied only to archive members.
4369 (f_mtime): Archive members always have low resolution time stamps.
4371 * configure.in: Remove --disable-nsec-timestamps, as this has
4372 been superseded by .LOW_RESOLUTION_TIME.
4374 2000-07-23 Paul Eggert <eggert@twinsun.com>
4376 * configure.in (enable_nsec_timestamps): Renamed from
4377 make_cv_nsec_timestamps, since enable/disable options
4378 shouldn't be cached.
4380 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4381 and Paul Eggert <eggert@twinsun.com>
4383 * file.c (file_timestamp_now):
4384 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4385 so that clock_gettime is not linked unless needed.
4387 * filedef.h (FILE_TIMESTAMP_HI_RES):
4388 Remove definition; "configure" now does this.
4390 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4391 to before high resolution file timestamp check,
4392 since that check now uses uintmax_t.
4393 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4394 high resolution file timestamps.
4395 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4396 so that we don't link in clock_gettime unnecessarily.
4398 2000-07-17 Paul D. Smith <psmith@gnu.org>
4400 * i18n/ja.po: New version of the translation file.
4402 2000-07-07 Paul D. Smith <psmith@gnu.org>
4404 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4405 the offset calculation.
4406 (name_mtime): Replace EINTR test with EINTR_SET macro.
4408 2000-07-07 Paul Eggert <eggert@twinsun.com>
4412 * remake.c (update_file_1):
4413 Avoid spurious rebuilds of archive members due to their
4414 timestamp resolution being only one second.
4415 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4416 the clock's resolution being lower than file timestamps'.
4417 When warning about future timestamps, report only the discrepancy,
4418 not the absolute value of the timestamp and the current time.
4420 * file.c (file_timestamp_now): New arg RESOLUTION.
4421 * filedef.h (file_timestamp_now): Likewise.
4422 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4424 2000-07-05 Paul D. Smith <psmith@gnu.org>
4426 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4427 to listp. Fixes PR/1793.
4429 2000-06-26 Paul Eggert <eggert@twinsun.com>
4431 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4433 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4435 * remake.c (f_mtime): Remove unused var memtime.
4437 2000-06-25 Martin Buchholz <martin@xemacs.org>
4439 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4440 Ran spell-check on make.texinfo.
4442 2000-06-23 Paul D. Smith <psmith@gnu.org>
4444 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4445 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4446 * make.h: Define these macros.
4448 * Version 3.79.1 released.
4450 * configure.in: Add a new option, --disable-nsec-timestamps, to
4451 avoid using sub-second timestamps on systems that support it. It
4452 can lead to problems, e.g. if your makefile relies on "cp -p".
4453 * README.template: Document the issue with "cp -p".
4455 * config.guess, config.sub: Updated.
