852 double-colons have a different meaning. Savannah bug #27497.
854 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
856 * configh.dos.template: Remove unconditional definition of
857 SYS_SIGLIST_DECLARED.
858 Include <sys/version.h> because ports of GCC 4.3.0 and later no
859 longer include it, so macros like __DJGPP_MINOR__ are no longer
860 defined automatically.
862 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
863 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
864 instead of using the hardcoded ones.
865 (SUBDIRS): doc subdir added.
866 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
867 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
868 create html formated docs. texi2html may not be ported to DOS.
869 (make.info, make.dvi, make.ps, make.html): Make targets depend on
871 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
872 -I switch to look in ./ instead of ./doc.
873 (html): Target depend on html-recursive instead of make_1.html.
874 (make_1.html): Removed.
875 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.

879 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
880 (tags-recursive): Allow for more than one subdir in the build
882 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
883 targets. Enter into doc/ to produce the targets.
884 (all-am): $(INFO_DEPS) replaced by info.
886 2009-09-26 Paul Smith <psmith@gnu.org>
888 * read.c (record_files): Use free_ns() to free struct nameseq.
891 * rule.c (freerule): Use free_dep_chain().
893 * read.c (record_files): Free FILENAMES chain for implicit rules.
894 (eval): Static pattern targets go into the string cache.
896 * function.c (string_glob): Free NAME in the nameseq chain.
898 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
900 * implicit.c (pattern_search): Terminate early if we haven't
901 found any rules to try (performance improvement).
903 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
905 * implicit.c (pattern_search): Merge three parallel arrays,
906 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
907 of struct TRYRULE. In the old version the latter two arrays
908 had insufficient length.
910 2009-09-24 Paul Smith <psmith@gnu.org>
912 * implicit.c (pattern_search): Add back support for order-only
913 prerequisites for secondary expansion implicit rules, that were
914 accidentally dropped. If we find a "|", enable order-only mode
915 and set IGNORE_MTIME on all deps that are seen afterward.
916 (pattern_search): Fix memory leaks: for intermediate files where
917 we've already set the file variable and pattern variable sets, be
918 sure to either save or free them as appropriate.
920 2009-09-23 Paul Smith <psmith@gnu.org>
922 Rework the way secondary expansion is stored, for efficiency.
923 This changes secondary expansion so that ONLY WHEN we know we have
924 a possibility of needing secondary expansion, do we defer the
925 secondary expansion. This means more parsing the deps but we use
926 a lot less memory (due to the strcache). Also, this fixes
929 * read.c (eval): Don't parse the dep string here anymore.
930 (record_files): Take the dep argument as an unparsed string. If
931 secondary expansion is enabled AND the prereq string has a '$' in
932 it, then set NEED_2ND_EXPANSION and keep the entire string.
933 Otherwise, parse the dep string here to construct the dep list
934 with the names in the strcache.
936 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
937 duplicate the name string (others are in the strcache).
939 * implicit.c: Remove struct idep and free_idep_chain(): unused.
940 (struct patdeps): New structure to store prereq information.
941 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
942 which prerequisites need expansion, and expand only those.
944 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
945 and enter_prereqs(). split_prereqs() takes a fully-expanded string
946 and splits it into a DEP list, handling order-only prereqs.
947 (enter_prereqs): This function enters a list of DEPs into the file
948 database. If there's a stem defined, expand any pattern chars.
949 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
950 set. Use the above functions.
951 (snap_deps): Only perform second expansion on prereqs that need it,
952 as defined by the NEED_2ND_EXPANSION flag.
953 (print_prereqs): New function to print the prereqs
954 (print_file): Call print_prereqs() rather than print inline.
956 * hash.h (STRING_COMPARE): Take advantage of strcache() by
958 (STRING_N_COMPARE): Ditto.
959 (ISTRING_COMPARE): Ditto.
961 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
962 (parse_file_seq): Return void*
963 * read.c (parse_file_seq): Return void*.
964 (eval): Invoke macroized version of parse_file_seq()
965 * default.c (set_default_suffixes): Ditto.
966 * file.c (split_prereqs): Ditto.
967 * function.c (string_glob): Ditto.
968 * main.c (main): Ditto.
969 * rule.c (install_pattern_rule): Ditto.
971 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
973 2009-09-16 Paul Smith <psmith@gnu.org>
975 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
977 * dep.h: Create alloc_dep() / free_dep() macros.
979 * implicit.c (pattern_search): Take advantage of the new
980 parse_file_seq() to add the directory prefix to each prereq.
982 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
983 all. Avoid reversing chains. Support adding prefixes.
984 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
985 cached/non-cached results.
986 (eval): Remove multi_glob() & invoke new parse_file_seq().
987 * rule.c (install_pattern_rule): Ditto.
988 * main.c (main): Ditto.
989 * implicit.c (pattern_search): Ditto.
990 * function.c (string_glob): Ditto.
991 * file.c (parse_prereqs): Ditto.
992 * default.c (set_default_suffixes): Ditto.
994 * variable.c (parse_variable_definition): Don't run off the end of
995 the string if it ends in whitespace (found with valgrind).
997 * commands.c (set_file_variables): Keep space for all targets in
998 $? if -B is given (found with valgrind).
1000 2009-09-15 Paul Smith <psmith@gnu.org>
1002 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
1003 (xcalloc): Add new function.
1004 * make.h: New declarations.

1015 * ar.c (ar_glob_match): Use xcalloc().
1016 * dir.c (file_impossible): Ditto.
1017 * file.c (enter_file): Ditto.
1018 * job.c (new_job): Ditto.
1019 * read.c (parse_file_seq): Ditto.
1020 * vmsfunctions.c (opendir): Ditto.

1038 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1039 (Include): Clarify the behavior of -include.
1040 Fixes Savannah bug #18963.
1042 2009-08-01 Paul Smith <psmith@gnu.org>
1044 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1045 etc. come on the command line. Fixes Savannah bug #27093.
1047 * expand.c (expand_argument): If the argument is large enough use
1048 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1050 * variable.c (do_variable_definition): Avoid using alloca() to
1051 hold values, which can be large. Fixes Savannah bug #23960.
1053 * job.c (new_job): Use memmove() instead of strcpy() since both
1054 pointers are in the same memory block. Fixes Savannah bug #27148.
1055 Patch by Petr Machata.
1057 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1059 * job.c (construct_command_argv_internal): Add "ulimit" and

1064 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1065 that set make_cv_sys_gnu_glob, so they are also correctly set
1066 when the cache has been populated before.
1068 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1070 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1071 exist, as realpath(3) does where it's supported.
1073 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1075 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1076 (abspath): Support systems that define HAVE_DOS_PATHS (have
1077 drive letters in their file names). Use IS_PATHSEP instead of a
1078 literal '/' comparison. Fixes Savannah bug #26886.
1080 2009-06-14 Paul Smith <psmith@gnu.org>
1082 * remake.c (update_file_1): Remember the original file we marked
1083 as updating, so we can clear that flag again. If we find a target
1084 via vpath, FILE might change.
1085 (check_dep): Ditto. Fixes Savannah bug #13529.
1086 Patch by Reid Madsen <reid.madsen@tek.com>.
1088 2009-06-13 Paul Smith <psmith@gnu.org>
1090 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1091 included by MAKEFILES cannot give default goals.
1092 * read.c (eval): If set_default is not set, pass the no-default-goal
1093 value when we read included makefiles. Fixes Savannah bug #13401.
1095 * ar.c (ar_name): Ensure that targets with empty parens aren't
1096 considered archive member references: archive members must have a
1097 non-empty "member" string. Fixes Savannah bug #18435.
1099 * function.c (string_glob): Rely on multi_glob() to determine
1100 whether files exist or not. Remove call to file_exists_p() which
1101 is not always correct. Fixes Savannah bug #21231.
1102 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1103 then only files that really exist will be returned.
1104 * dep.h: Add new argument to multi_glob().
1105 * rule.c (install_pattern_rule): Ditto.
1106 * read.c (eval): Ditto.
1107 * main.c (main): Ditto.
1108 * implicit.c (pattern_search): Ditto.
1109 * file.c (parse_prereqs): Ditto.
1110 * default.c (set_default_suffixes): Ditto.
1112 2009-06-09 Paul Smith <psmith@gnu.org>
1114 * commands.c (set_file_variables): If always_make_flag is set,
1115 always add the prereq to $?. Fixes Savannah bug #17825.
1117 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1118 to rebuild the deps of all the also_make targets for that file.
1119 Fixes Savannah bug #19108.
1121 * implicit.c (pattern_search): Undo test for is_target, added by
1122 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1123 Rule Search Algorithm". Fixes Savannah bug #17752.
1125 * main.c (clean_jobserver): Clear the jobserver_fds options and
1126 set job_slots to the default when we clean up.
1127 (define_makeflags): Return the new MAKEFLAGS value.
1128 (main): Reset MAKEFLAGS in the environment when we re-exec.
1129 Fixes Savannah bug #18124.
1131 2009-06-08 Paul Smith <psmith@gnu.org>
1133 * read.c (eval): Collapse continuations post-semicolon on target-
1134 specific variables. Fixes Savannah bug #17521.
1136 2009-06-07 Paul Smith <psmith@gnu.org>
1138 * job.c (reap_children): For older systems without waitpid() (are
1139 there any of these left?) run wait(2) inside EINTRLOOP to handle
1140 EINTR errors. Fixes Savannah bug #16401.
1142 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1144 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1146 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1147 not the end, to catch second expansion $(eval ...) defining new
1148 target/prereq relationships during snap_deps.
1149 Fixes Savannah bug #24622.
1151 * read.c (record_files): The second-expansion "f->updating" hack
1152 was not completely correct: if assumed that the target with
1153 commands always had prerequisites; if one didn't then the ordering
1154 was messed up. Fixed for now to use f->updating to decide whether
1155 to preserve the last element in the deps list... but this whole
1156 area of constructing and reversing the deps list is too confusing
1157 and needs to be reworked. Fixes Savannah bug #21198.
1159 2009-06-06 Paul Smith <psmith@gnu.org>
1161 * hash.c (hash_insert): Remove useless test for NULL.
1162 Fixes Savannah bug #21823.
1164 * make.h: Move SET_STACK_SIZE determination to make.h.
1165 * main.c (main): New global variable, STACK_LIMIT, holds the
1166 original stack limit when make was started.
1167 * job.c (start_job_command): Reset the stack limit, if we changed it.
1168 Fixes Savannah bug #22010.
1170 * remake.c (check_dep): Only set the target's state to not-started
1171 if it's not already running. Found this while testing -j10 builds
1172 of glibc: various targets were being rebuilt multiple times.
1173 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1176 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1177 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1180 2009-06-04 Paul Smith <psmith@gnu.org>
1182 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1184 * maintMakefile: Modify access of config and gnulib Savannah
1185 modules to use GIT instead of CVS.
1187 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1188 Fixes Savannah bug #24655.
1190 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1191 this can happen during some invocations of $(eval ...) for example.
1192 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1194 2009-06-02 Paul Smith <psmith@gnu.org>
1196 * configure.in: Check for fileno()
1197 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1198 for the makefile file so invocations of $(shell ...) don't inherit it.
1199 Fixes Savannah bug #24277.
1201 2009-06-01 Paul Smith <psmith@gnu.org>
1203 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1204 expansion was handled incorrectly. Rework the default goal
1205 handling to save the variable only. Remove default_goal_file and
1207 * read.c (eval): Check default_goal_var, not default_goal_name.
1208 * read.c (record_target_var): Don't check default_goal_file here.
1210 2009-05-31 Paul Smith <psmith@gnu.org>
1212 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1213 it, and if the multi_glob() returns nothing (say it expanded to
1214 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1216 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1217 $(and ..) to the reference. Fixes Savannah bug #25694.
1219 * make.1: Be clear that some recipes will be executed even with -n.
1220 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1222 * doc/make.texi (Override Directive): Make more clear how
1223 overrides and appends interact.
1224 Elucidates part of Savannah bug #26207.
1226 * read.c (record_target_var): Don't reset the origin on
1227 target-specific variables; try_variable_definition() will handle
1228 this correctly. Fixes Savannah bug #26207.
1230 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1231 Fixes Savannah bug #25712.
1233 * implicit.c (pattern_search): Keep a pointer to the beginning of
1234 the filename and save that instead of the constructed pointer.
1235 Fixes Savannah bug #26593.
1236 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1238 2009-05-30 Paul Smith <psmith@gnu.org>
1240 * doc/make.texi (Multi-Line): Add a description of the new abilities
1241 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1242 "command sequence" vs. "recipe" syntax.
1243 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1244 after a define, to create variables with those flavors.
1246 2009-05-25 Paul Smith <psmith@gnu.org>
1248 Reworked the parser for variable assignments to allow multiple
1249 modifiers, and in any order. Also allows variable and
1250 prerequisites to be modifier names ('export', 'private', etc.)
1252 * NEWS: Add notes about user-visible changes.
1254 * read.c (struct vmodifiers): Remember what modifiers were seen.
1255 (parse_var_assignment): New function to parse variable assignments.
1256 (eval): Call the new function. Handle variable assignments earlier.
1258 * variable.c (parse_variable_definition): Only parse; don't create var.
1259 (assign_variable_definition): Call parse, then create the var.
1261 2009-05-24 Paul Smith <psmith@gnu.org>
1263 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1264 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1266 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1268 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1269 Fixes Savannah bug #25412.
1271 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1272 prototype for xmalloc.
1273 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1274 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1275 Loop over an array of extensions, instead of duplicating the same
1276 code inline. Use SearchPath followed by CreateFile, instead of
1277 the obsolete OpenFile. Fixes Savannah bug #17277.
1278 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1279 to `find_file'. Fixes Savannah bug #25662.
1281 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1283 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1284 Fixes Savannah bug #20495.
1286 2009-02-28 Ralf Wildenhues <address@hidden>
1288 * doc/make.texi (Instead of Execution): Document interaction of
1289 -t with phony targets.
1291 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1293 Introduce a new keyword "private" which applies to target-specific
1294 variables and prevents their values from being inherited.
1296 * variable.h (struct variable): Add private_var flag to each variable.
1297 Add a flag to specify which list entry switches to the parent target.
1298 * variable.c (define_variable_in_set): Initialize private_var flag.
1299 (lookup_variable): Skip private variables in parent contexts.
1300 (initialize_file_variables): Set next_is_parent appropriately.
1301 (print_variable): Show the private_var flag.

1303 (record_target_var): Set private_var.
1304 * doc/make.texi (Suppressing Inheritance): Add documentation.
1306 2008-10-26 Paul Smith <psmith@gnu.org>
1308 * configure.in: Check for strndup().

1311 * make.h: Rename savestring to xstrndup.
1312 * commands.c (chop_commands): Ditto.
1313 * function.c (func_foreach): Ditto.
1314 * read.c (eval, record_files): Ditto.
1315 * variable.c (define_variable_in_set): Ditto.
1317 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1319 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1322 * w32/subproc/build.bat (GCCBuild): Likewise.
1324 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1326 * job.c (construct_command_argv_internal): Avoid extra backslash
1327 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1330 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1332 * README.W32.template: Remove obsolete text about non-support for
1333 -jN without Unixy shell. Remove obsolete text about not supplying
1334 Visual Studio project files (we do supply them). Modify text to
1335 prefer GCC builds to MSC builds.
1337 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1339 * doc/make.texi (Empty Targets): Fix typo.
1341 2008-03-27 Paul Smith <psmith@gnu.org>
1343 Fix Savannah bug #22379:
1344 * ar.c (ar_glob_match): Zero the allocated structure.
1345 * read.c (parse_file_seq): Ditto.
1347 2008-03-08 Brian Dessent <brian@dessent.net>
1349 * maintMakefile: Update Translation Project location.
1351 2008-01-26 Eli Zaretskii <eliz@gnu.org>
1353 * variable.c (target_environment): Don't use shell_var if its
1354 `value' field is NULL.
1356 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1358 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1360 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1361 (TEXINFOS): Value changed to `doc/make.texi'.
1362 (.SUFFIXES): Use .texi instead of .texinfo.
1363 (make.info, make.dvi): Depend on doc/make.texi.
1364 (.texi.info): New target, instead of ".texinfo.info". Change -I
1365 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1366 (.texi): New target, instead of ".texinfo". Change -I switch to
1367 $(MAKEINFO) to look in doc/. Use --no-split.
1368 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1369 switch to $(MAKEINFO) to look in doc/.
1370 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1371 "*.i[0-9][0-9]" (due to --no-split above).
1372 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1373 (html, make_1.html): New targets.
1374 (.PHONY): Add "html".
1375 (.SUFFIXES): Add .html.
1377 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1379 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1380 HAVE_DECL_SYS_SIGLIST.
1382 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1383 build does not use child_execute_job.
1385 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1386 export the SHELL environment variable to the child.
1388 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1390 * config.h.W32: Include sys/types.h.
1391 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1393 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
1394 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
1397 2007-11-04 Paul Smith <psmith@gnu.org>
1399 * doc/make.texi: Convert references to "commands", "command
1400 lines", and "command script" to "recipe".
1402 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
1405 2007-10-27 Bruno Haible <bruno@clisp.org>
1407 * remake.c (f_mtime): Print time difference values between 100 and
1408 ULONG_MAX in fixed-point notation rather than in exponention notation.
1410 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1412 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1413 a more complex value than a simple shell: if it's not a default
1414 shell now then expand it and see if is a default shell then.
1416 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1418 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1419 pathnames, with const strings.
1420 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1421 from the template (used for building from CVS, not a dist).
1423 2007-10-10 Paul Smith <psmith@gnu.org>
1425 * make.h: Add a prototype for w32_kill() (change suggested by
1426 Yongwei Wu <wuyongwei@gmail.com>).
1428 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1430 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1431 directories in Path.
1433 2007-09-12 Paul Smith <psmith@gnu.org>
1435 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
1436 Provided by Diego Biurrun <diego@biurrun.de>
1437 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1438 Provided by Diego Biurrun <diego@biurrun.de>
1440 2007-09-11 Paul Smith <psmith@gnu.org>
1442 * doc/make.texi (Special Variables): Moved this into the "How to
1443 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1444 (MAKEFILE_LIST) No longer a section; this was added into the
1445 "Special Variables" section.
1446 (Rule Introduction): Reference .RECIPEPREFIX.
1447 (Simple Makefile): Ditto.
1448 (Rule Syntax): Ditto.
1449 (Command Syntax): Ditto.
1450 (Error Messages): Ditto.
1452 2007-09-10 Paul Smith <psmith@gnu.org>
1454 * commands.c (print_commands): Don't print an extra line in the
1455 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1457 * read.c (construct_include_path): Add the full string to the cache; we
1458 were chopping the last char.
1460 * NEWS: Announce the .RECIPEPREFIX special variable.
1461 * variable.c (lookup_special_var): Rename from handle_special_var().
1462 (lookup_variable): Call the new name.
1463 (set_special_var): New function: handle setting of special variables.
1464 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1465 (do_variable_definition): Call it.
1466 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1467 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1468 * main.c (main): Create the .RECIPEPREFIX special variable.
1469 * read.c (eval): Remove the cmd_prefix characters from the command
1470 scripts here, so they're not stored in the commands array at all,
1471 rather than waiting and stripping them out during command construction.
1472 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1474 2007-08-15 Paul Smith <psmith@gnu.org>
1476 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1477 file has had the section info removed, so add some to make.texi
1478 before we include it.
1480 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1482 * remake.c (check_dep): Reset the target state for intermediate
1483 files. They might have been considered before but not updated
1484 then (order-only for example) but they will be this time.
1485 Fixes Savannah bug #'s 3330 and 15919.
1487 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1489 Fix Savannah bug #20549:
1490 * function.c (func_shell): Call construct_command_argv with zero
1492 * job.c (construct_command_argv_internal): New argument FLAGS; all
1494 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1496 * job.h (construct_command_argv_internal): Update prototype.
1498 2007-07-13 Paul Smith <psmith@gnu.org>
1500 * file.c (expand_deps): Use variable_buffer as the start of the
1501 buffer, not the original pointer (in case it was reallocated).
1502 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1503 Fixes Savannah bug #20452.
1505 2007-07-04 Paul Smith <psmith@gnu.org>
1507 * (ALL FILES): Update to GPLv3.
1508 * (ALL FILES): Update copyright for 2007.
1510 * main.c (print_version): Move the host type info to the second line.
1512 2007-06-29 Thiemo Seufer <ths@mips.com>
1514 * maintMakefile: Update Translation Project location.
1516 2007-06-13 Paul Smith <psmith@gnu.org>
1518 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1519 "Expansion of a deferred"
1520 Fixes Savannah bug #20018.
1522 * expand.c (variable_expand_for_file): Preserve the value of
1523 reading_file rather than setting it to 0 at the end.
1524 Fixes Savannah bug #20033.
1526 2007-05-11 Paul Smith <psmith@gnu.org>
1528 * job.c (new_job): Add debug info to specify where make found the
1529 command script it is running to build a target.
1530 Fixes Savannah bug #18617.
1532 * default.c (default_suffixes,default_suffix_rules,default_variables):
1533 Add support for Objective C. Fixes Savannah bug #16389.
1534 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1536 * function.c (func_lastword): Initialize p.
1538 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1539 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1540 Dave Korn <dave.korn@artimi.com>
1542 2007-05-08 Paul Smith <psmith@gnu.org>
1544 Fix Savannah bug #19656:
1546 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1548 * make.h: Change all case-insensitive string compares to use
1549 strcasecmp() (from POSIX). If we don't have that but do have one
1550 of the others, define strcasecmp to be one of those instead. If
1551 we don't have any, declare a prototype for our own version.
1553 * misc.c (strcasecmp): Use this if we can't find any native
1554 case-insensitive string comparison function.
1555 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1556 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1558 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1559 strcasecmp() instead of stricmp().
1560 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1561 instead of strcmpi().
1562 * acinclude.m4: Remove the strcasecmp() check from here.
1564 2007-03-21 Paul Smith <psmith@gnu.org>
1566 * configure.in: Don't turn on case-insensitive file system support
1567 if --disable-... is given. Fixes Savannah bug #19348.
1569 2007-03-19 Paul Smith <psmith@gnu.org>
1571 * ALL: Use the strcache for all file name strings, or other
1572 strings which we will never free. The goal is to save memory by
1573 avoiding duplicate copies of strings. However, at the moment this
1574 doesn't save much memory in most situations: due to secondary
1575 expansion we actually save prerequisite lists twice (once before
1576 the secondary expansion, and then again after it's been parsed
1577 into individual file names in the dep list). We will resolve this
1578 in a future change, by doing the parsing up-front for targets
1579 where secondary expansion is not set.
1581 Moving things into the strcache also allows us to use const
1582 pointers in many more places.

1586 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1587 the function, not just the first. Fixes Savannah bug #18680.
1589 2006-11-18 Paul Smith <psmith@gnu.org>
1591 * strcache.c (strcache_add_len): Don't allocate a new buffer
1592 unless the string is not already nil-terminated. Technically this
1593 is a violation of the standard, since we may be passed an array
1594 that is not long enough to test one past. However, in make this
1595 is never true since we only use nil-terminated strings or
1596 sub-strings thereof.
1598 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1600 * main.c: New global cmd_prefix, defaults to '\t'.

1635 point to lastword since the example was updated.
1636 Fixes Savannah bug #16304.

1695 that don't have extended grep.

1764 Declare and define sh_chars_sh[].
1766 2006-03-23 Paul D. Smith <psmith@gnu.org>
1768 * configure.in: Look for build.sh.in in $srcdir so it will be
1769 built for remote configurations as well.
1771 * Makefile.am: Make sure to clean up build.sh during distclean.
1772 Fixes Savannah bug #16166.
1774 * misc.c (log_access): Takes a const char *.
1775 * function.c (fold_newlines): Takes an unsigned int *.
1776 Both fixes for Savannah bug #16170.
1778 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1780 * implicit.c (pattern_search): Call set_file_variables only
1781 if we have prerequisites that need second expansion. Fixes
1782 Savannah bug #16140.
1784 2006-03-19 Paul D. Smith <psmith@gnu.org>
1786 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1787 memory on hosts that don't support it directly.
1789 * README.cvs: Add information on steps for making a release (to
1790 make sure I don't forget any).
1792 * main.c (clean_jobserver): Move jobserver cleanup code into a new

1802 allow multiple concurrent runs.
1803 Patch from Joseph Myers <joseph@codesourcery.com>
1805 2006-03-17 Boris Kolpackov <boris@kolpackov.net>

1809 (copy_dep_chain): Copy stem.
1810 (free_dep_chain): Use free_dep.
1811 * read.c (record_files): Store stem in the dependency line.
1812 * file.c (expand_deps): Use stem stored in the dependency line. Use
1813 free_dep_chain instead of free_ns_chain.

1826 Fixes Savannah bug #15913.
1828 2006-03-09 Paul Smith <psmith@gnu.org>
1830 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1831 listed non-existent files as changed. Turns out there's a bug in
1832 the Linux kernel builds which means that this change causes
1833 everything to rebuild every time. We will re-introduce this fix
1834 in the next release, to give them time to fix their build system.
1835 Fixes Savannah bug #16002.
1836 Introduces Savannah bug #16051.

1853 2006-02-19 Paul D. Smith <psmith@gnu.org>
1855 * commands.c (set_file_variables): Realloc, not malloc, the static
1856 string values to avoid memory leaks.
1858 * expand.c (recursively_expand_for_file): Only set reading_file to
1859 an initialized value.
1861 * implicit.c (pattern_search): We need to make a copy of the stem
1862 if we get it from an intermediate dep, since those get freed.
1864 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1866 (enter_file) [VMS]: Ditto.
1867 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

1871 * job.c (construct_command_argv_internal): Fix last change.
1873 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1874 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1875 the calls to _beginthreadex.
1877 * expand.c (recursively_expand_for_file): Initialize `save' to
1878 prevent compiler warnings.
1880 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1882 * job.c (construct_command_argv_internal): Don't create a temporary
1883 script/batch file if we are under -n. Call _setmode to switch the
1884 script file stream to text mode.

1888 * variable.c (merge_variable_set_lists): Don't try to merge the
1889 global_setlist. Not only is this useless, but it can lead to
1890 circularities in the linked list, if global_setlist->next in one
1891 list gets set to point to another list which also ends in

1897 Fix for Savannah bug #106.
1899 * expand.c (expanding_var): Keep track of which variable we're
1900 expanding. If no variable is being expanded, it's the same as
1902 * make.h (expanding_var): Declare it.
1903 * expand.c (recursively_expand_for_file): Set expanding_var to the
1904 current variable we're expanding, unless there's no file info in
1905 it (could happen if it comes from the command line or a default
1906 variable). Restore it before we exit.

1918 * read.c (eval): Even if the included filenames expands to the
1919 empty string we still need to free the allocated buffer.
1921 * implicit.c (pattern_search): If we allocated a variable set for
1922 an impossible file, free it.
1923 * variable.c (free_variable_set): New function.
1924 * variable.h: Declare it.
1926 * read.c (read_all_makefiles): Makefile names are kept in the
1927 strcache, so there's never any need to alloc/free them.
1930 * main.c (main): Add "archives" to the .FEATURES variable if
1931 archive support is enabled.
1932 * doc/make.texi (Special Variables): Document it.

1942 * (ALL FILES): Updated copyright and license notices.
1944 2006-02-10 Paul D. Smith <psmith@gnu.org>
1946 A new internal capability: the string cache is a read-only cache
1947 of strings, with a hash table interface for fast lookup. Nothing
1948 in the cache will ever be freed, so there's no need for reference
1949 counting, etc. This is the beginning of a full solution for
1950 Savannah bug #15182, but for now we only store makefile names here.
1952 * strcache.c: New file. Implement a read-only string cache.
1953 * make.h: Add prototypes for new functions.
1954 * main.c (initialize_global_hash_tables): Initialize the string cache.
1955 (print_data_base): Print string cache stats.
1956 * read.c (eval_makefile): Use the string cache to store makefile
1957 names. Rewrite the string allocation to be sure we free everything.

1961 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1962 directory time stamp didn't change, except on FAT filesystems.

1987 -W, don't overwrite it with the real mtime.

2006 * filedef.h (struct file): Add a new LAST pointer.
2008 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
2009 the comparison. For 64-bits systems the result of the subtraction
2010 might not fit into an int. Use comparison instead.
2011 Fixes Savannah bug #15534.
2013 * doc/make.texi: Update the chapter on writing commands to reflect
2014 the changes made in 3.81 for backslash/newline and SHELL handling.

2034 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2036 * remake.c (update_goal_chain): Set g->changed instead of
2037 incrementing it, as it is only 8-bit wide, and could overflow if

2060 the shell is not sh.exe.
2062 * job.c (create_batch_file): Renamed from create_batch_filename;
2063 all callers changed. Don't close the temporary file; return its
2064 file descriptor instead. New arg FD allows to return the file
2066 (construct_command_argv_internal): Use _fdopen instead of fopen to
2067 open the batch file.

2098 * doc/make.texi (Execution): Add a footnote about changes in
2099 handling of backslash-newline sequences. Mention the differences
2100 on MS-DOS and MS-Windows.
2102 * NEWS: More details about building the MinGW port and a pointer
2103 to README.W32. Fix the section name that describes the new
2104 backward-incompatible processing of backslash-newline sequences.
2105 The special processing of SHELL set to "cmd" is only relevant to
2106 MS-Windows, not MS-DOS.
2108 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2110 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2111 to DWORD, to avoid compiler warnings.
2112 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2113 use %ld in format, to avoid compiler warnings.
2115 * doc/make.texi (Special Targets): Fix a typo.
2116 (Appending): Fix cross-reference to Setting.
2117 (Special Variables, Secondary Expansion, File Name Functions)
2118 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2119 periods after a sentence.
2120 (Execution): Add @: after "e.g.".
2121 (Environment): Fix punctuation.
2122 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2123 (Shell Function, Target-specific): Add @: after "vs."
2125 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2127 * read.c (record_target_var): Initialize variable's export field
2128 with v_default instead of leaving it "initialized" by whatever
2129 garbage happened to be on the heap.
2131 2005-12-12 Paul D. Smith <psmith@gnu.org>
2133 * make.1: Fix some display errors and document all existing options.
2134 Patch by Mike Frysinger <vapier@gentoo.org>.
2136 2005-12-11 Paul D. Smith <psmith@gnu.org>
2138 * implicit.c (pattern_search): If 2nd expansion is not set for
2139 this implicit rule, replace the pattern with the stem directly,
2140 and don't re-expand the variable list. Along with the other
2141 .SECONDEXPANSION changes below, fixes bug #13781.
2143 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2145 * implicit.c (pattern_search): Mark other files that this rule
2146 builds as targets so that they are not treated as intermediates
2147 by the pattern rule search algorithm. Fixes bug #13022.
2149 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2151 * remake.c (notice_finished_file): Propagate the change of
2152 modification time to all the double-colon entries only if
2153 it is the last one to be updated. Fixes bug #14334.
2155 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2157 * function.c (func_flavor): Implement the flavor function which
2158 returns the flavor of a variable.
2159 * doc/make.texi (Functions for Transforming Text): Document it.
2160 * NEWS: Add it to the list of new functions.
2162 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2164 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2166 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2167 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2169 2005-10-26 Paul Smith <psmith@gnu.org>
2171 * read.c (record_files): Don't set deps flags if there are no deps.
2172 * maintMakefile: We only need to build the templates when we are
2173 creating a distribution, so don't do it for "all".
2175 2005-10-24 Paul D. Smith <psmith@gnu.org>
2177 Make secondary expansion optional: its enabled by declaring the
2178 special target .SECONDEXPANSION.
2180 * NEWS: Update information on second expansion capabilities.
2181 * doc/make.texi (Secondary Expansion): Document the
2182 .SECONDEXPANSION special target and its behavior.
2183 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2184 prerequisite list was found in a static pattern rule.
2185 (free_dep_chain): Declare a prototype.
2186 * file.c (parse_prereqs): New function: break out some complexity
2188 (expand_deps): If we aren't doing second expansion, replace % with
2189 the stem for static pattern rules. Call the new function.
2190 * filedef.h (parse_prereqs): Declare a prototype.
2191 * implicit.c (pattern_search): Initialize the new staticpattern
2193 * main.c (second_expansion): Declare a global variable to remember
2194 if the special target has been seen. Initialize the new
2195 staticpattern field for prerequisites.
2196 * make.h: Extern for second_expansion.
2197 * misc.c (free_dep_chain): New function: frees a struct dep list.
2198 * read.c (read_all_makefiles): Initialize the staticpattern field.
2199 (eval_makefile): Ditto.
2200 (record_files): Check for the .SECONDEXPANSION target and set
2201 second_expansion global if it's found.
2202 Use the new free_dep_chain() instead of doing it by hand.
2203 Set the staticpattern field for prereqs of static pattern targets.
2205 2005-10-16 Paul D. Smith <psmith@gnu.org>
2207 * main.c (main): Set CURDIR to be a file variable instead of a
2208 default, so that values of CURDIR inherited from the environment
2209 won't override the make value.
2211 2005-09-26 Paul D. Smith <psmith@gnu.org>
2213 * job.c (construct_command_argv_internal): If the line is empty
2214 remember to free the temporary argv strings.
2217 2005-09-16 Paul D. Smith <psmith@gnu.org>
2219 * job.c (start_job_command): The noerror flag is a boolean (single
2220 bit); set it appropriately.
2221 Reported by Mark Eichin <eichin@metacarta.com>
2223 2005-08-29 Paul D. Smith <psmith@gnu.org>
2225 * function.c (func_error): On Windows, output from $(info ...)
2226 seems to come in the wrong order. Try to force it with fflush().
2228 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2230 * read.c (record_files): Move code that sets stem for static
2231 pattern rules out of the if (!two_colon) condition so it is
2232 also executed for two-colon rules. Fixes Savannah bug #13881.
2234 2005-08-08 Paul D. Smith <psmith@gnu.org>
2236 * make.h: Don't test that __STDC__ is non-0. Some compilers
2237 (Windows for example) set it to 0 to denote "ISO C + extensions".
2240 2005-08-07 Paul D. Smith <psmith@gnu.org>
2242 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2243 conditional (slightly different version of a fix from Eli).
2245 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2246 If make is running in parallel without -k and two jobs die in a
2247 row, but not too close to each other, then make will quit without
2248 waiting for the rest of the jobs to die.
2250 * main.c (die): Don't reset err before calling reap_children() the
2251 second time: we still want it to be in the error condition.
2252 * job.c (reap_children): Use a static variable, rather than err,
2253 to control whether or not the error message should be printed.
2255 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2257 * w32/subproc/sub_proc.c: Include signal.h.
2258 (process_pipe_io, process_file_io): Pass a pointer to a local
2259 DWORD variable to GetExitCodeProcess. If the exit code is
2260 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2262 * job.c [WINDOWS32]: Include windows.h.
2263 (main_thread) [WINDOWS32]: New global variable.
2264 (reap_children) [WINDOWS32]: Get the handle for the main thread
2265 and store it in main_thread.
2267 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2268 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2269 doing anything else. When we are done, close the main thread
2270 handle and exit with status 130.
2272 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2274 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2277 * main.c (find_and_set_default_shell): If found a DOSish shell,
2278 set sh_found and the value of default_shell, and report the
2279 findings in debug mode.
2281 * job.c (construct_command_argv_internal): Check unixy_shell, not
2282 no_default_sh_exe, to decide whether to use Unixy or DOSish
2285 * README.W32: Update with info about the MinGW build.
2287 * build_w32.bat: Support MinGW.
2289 * w32/subproc/build.bat: Likewise.
2291 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2292 printing DWORD args.
2294 * function.c (windows32_openpipe): Fix format strings for printing
2297 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2299 (start_job_command): Fix format string for printing the result of
2301 (start_job_command) [WINDOWS32]: Do not define.
2302 (exec_command): Fix format string for printing HANDLE args.
2304 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2305 to avoid compiler warnings.
2306 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2307 (Note: some of these fixes were submitted independently by J. Grant)
2309 2005-07-30 J. Grant <jg@jguk.org>
2311 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2312 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2313 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2315 2005-07-15 Paul Smith <psmith@gnu.org>
2317 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2318 we don't have a POSIX shell, then revert to the old
2319 backslash-newline behavior (where they are stripped).
2322 2005-07-08 Paul D. Smith <psmith@gnu.org>
2324 * config.h.W32.template: Reorder to match the standard config.h,
2325 for easier comparisons.
2326 From J. Grant <jg@jguk.org>
2328 * maintMakefile: Remove .dep_segment before overwriting it, in
2329 case it's not writable or noclobber is set.
2330 * expand.c (variable_expand_string): Cast result of pointer
2331 arithmetic to avoid a warning.
2332 * main.c (switches): Add full-fledged final initializer.
2334 2005-07-06 Paul D. Smith <psmith@gnu.org>
2336 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2337 * signame.c (strsignal): If we found _sys_siglist[] or
2338 __sys_siglist[] use those instead of sys_siglist[].
2339 From Albert Chin <china@thewrittenword.com>
2341 2005-07-04 Paul D. Smith <psmith@gnu.org>
2343 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2344 globfree(); set up to use the GNU versions.
2345 From Martin Zinser <zinser@zinser.no-ip.info>
2347 2005-07-03 Paul D. Smith <psmith@gnu.org>
2349 From J. Grant <jg@jguk.org>:
2351 * README.W32.template: Update the Windows and tested MSVC versions.
2352 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2353 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2354 * build_w32.bat: Ditto.
2355 * w32/subproc/build.bat: Ditto.
2357 2005-06-28 Paul D. Smith <psmith@gnu.org>
2359 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2360 declaration was checked but not present.
2362 2005-06-27 Paul D. Smith <psmith@gnu.org>
2364 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2365 to unsigned long. Fixes Savannah bug #13550.
2367 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2368 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2369 Fixes Savannah bug #13551.
2371 2005-06-26 Paul D. Smith <psmith@gnu.org>
2373 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2374 it if ANSI_STRING is not set.
2376 2005-06-25 Paul D. Smith <psmith@gnu.org>
2378 * read.c (eval): If no filenames are passed to any of the
2379 "include" variants, don't print an error.
2380 * doc/make.texi (Include): Document this.
2381 Fixes Savannah bug #1761.
2383 * job.c (construct_command_argv_internal): Sanitize handling of
2384 backslash/newline pairs according to POSIX: that is, keep the
2385 backslash-newline in the command script, but remove a following
2386 TAB character, if present. In the fast path, make sure that the
2387 behavior matches what the shell would do both inside and outside
2388 of quotes. In the slow path, quote the backslash and put a
2389 literal newline in the string.
2390 Fixes Savannah bug #1332.
2391 * doc/make.texi (Execution): Document the new behavior and give
2393 * NEWS: Make a note of the new behavior.
2395 * make.h [WINDOWS32]: #include <direct.h>.
2396 Fixes Savannah bug #13478.
2398 * remake.c (name_mtime): If the stat() of a file fails and the -L
2399 option was given and the file is a symlink, take the best mtime of
2400 the symlink we can get as the mtime of the file and don't fail.
2401 Fixes Savannah bug #13280.
2403 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2404 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2405 inside a variable reference. Make this function static as it's
2407 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2408 parsing an unexpanded line looking for semicolons.
2409 Fixes Savannah bug #1454.
2410 * misc.c (remove_comments): Move this to read.c and make it static
2411 as it's only used there. Call find_char_unquote() with new arg.
2412 * make.h: Remove prototypes for find_char_unquote() and
2413 remove_comments() since they're static now.
2415 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2416 its export flag and obtain its value. When we need to re-exec,
2417 increment the value and add it into the environment.
2418 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2419 * NEWS: Mention MAKE_RESTARTS.
2420 * main.c (always_make_set): New variable. Change the -B option to
2421 set this one instead.
2422 (main): When checking makefiles, only set always_make_flag if
2423 always_make_set is set AND the restarts flag is 0. When building
2424 normal targets, set it IFF always_make_set is set.
2425 (main): Avoid infinite recursion with -W, too: only set what-if
2426 files to NEW before we check makefiles if we've never restarted
2427 before. If we have restarted, set what-if files to NEW _after_ we
2429 Fixes Savannah bug #7566:
2431 2005-06-17 Paul D. Smith <psmith@gnu.org>
2433 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2434 in the prerequisites list.
2436 2005-06-12 Paul D. Smith <psmith@gnu.org>
2438 Fix Savannah bug # 1328.
2440 * configure.in: Check for atexit().
2441 * misc.c (close_stdout): Test stdout to see if writes to it have
2442 failed. If so, be sure to exit with a non-0 error code. Based on
2443 code found in gnulib.
2444 * make.h: Prototype.
2445 * main.c (main): Install close_stdout() with atexit().
2447 2005-06-10 Paul D. Smith <psmith@gnu.org>
2449 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2451 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2452 headers; make vmsWaitForChildren() static; extern vmsify().
2453 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2454 Don't create child_execute_job() here (it's in vmsjobs.c).
2455 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2457 2005-06-09 Paul D. Smith <psmith@gnu.org>
2459 * variable.c (push_new_variable_scope): File variables point
2460 directly to the global_setlist variable. So, inserting a new
2461 scope in front of that has no effect on those variables: they
2462 don't go through current_variable_set_list. If we're pushing a
2463 scope and the current scope is global, push it "the other way" so
2464 that the new setlist is in the global_setlist variable, and
2465 next points to a new setlist with the global variable set.
2466 (pop_variable_scope): Properly undo a push with the new
2468 Fixes Savannah bug #11913.
2470 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2472 * job.c (reap_children): Don't die of the command failed but
2473 the dontcare flag is set. Fixes Savannah bug #13216.
2475 * implicit.c (pattern_search): When creating a target from
2476 an implicit rule match, lookup pattern target and set precious
2477 flag in a newly created target. Fixes Savannah bug #13218.
2479 2005-05-13 Paul D. Smith <psmith@gnu.org>
2481 Implement "if... else if... endif" syntax.
2483 * read.c (eval): Push all checks for conditional words ("ifeq",
2484 "else", etc.) down into the conditional_line() function.
2485 (conditional_line): Rework to allow "else if..." clause. New
2486 return value -2 for lines which are not conditionals. The
2487 ignoring flag can now also be 2, which means "already parsed a
2488 true branch". If that value is seen no other branch of this
2489 conditional can be considered true. In the else parsing if there
2490 is extra text after the else, invoke conditional_line()
2491 recursively to see if it's another conditional. If not, it's an
2492 error. If so, raise the conditional value to this level instead
2493 of creating a new conditional nesting level. Special check for
2494 "else" and "endif", which aren't allowed on the "else" line.
2495 * doc/make.texi (Conditional Syntax): Document the new syntax.
2497 2005-05-09 Paul D. Smith <psmith@gnu.org>
2499 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2500 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2501 recurses to the w32 directory, even on non-Windows systems. Use
2502 the method suggested in the automake manual.
2503 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2504 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2506 2005-05-07 Paul D. Smith <psmith@gnu.org>
2508 * main.c (die): If we're dying with a fatal error (not that a
2509 command has failed), write back any leftover tokens before we go.
2511 * job.c (set_child_handler_action_flags): If there are jobs
2512 waiting for the load to go down, set an alarm to go off in 1
2513 second. This allows us to wake up from a potentially long-lasting
2514 read() and start a new job if the load has gone down. Turn it off
2516 (job_noop): Dummy signal handler function.
2517 (new_job): Invoke it with the new semantics.
2519 * docs/make.texi: Document secondary expansion. Various cleanups
2522 2005-05-03 Paul D. Smith <psmith@gnu.org>
2524 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2525 the targets which are to ultimately be made are called "goals";
2526 see the GNU make manual. Also, MAKECMDGOALS, etc.
2528 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2529 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2530 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2532 2005-05-02 Paul D. Smith <psmith@gnu.org>
2534 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2535 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2536 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2537 functions to vmsjobs.c. #include it into jobs.c.
2539 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2540 jobserver tokens. I found that this happens when an exported
2541 recursive variable contains a $(shell ...) function reference: in
2542 this situation we could "forget" to write back a token.
2544 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2545 we have. It's not reliable to depend on the number of children in
2546 our linked list so keep a separate count.
2547 (new_job): Check jobserver_tokens rather than children &&
2548 waiting_jobs. Increment jobserver_tokens when we get one.
2549 (free_child): If jobserver_tokens is 0, internal error. If it's
2550 >1, write a token back to the jobserver pipe (we don't write a
2551 token for the "free" job). Decrement jobserver_tokens.
2553 * main.c: Add variable master_job_slots.
2554 (main): Set it to hold the number of jobs requested if we're the
2555 master process, when using the jobserver.
2556 (die): Sanity checks: first test jobserver_tokens to make sure
2557 this process isn't holding any tokens we didn't write back.
2558 Second, if master_job_slots is set count the tokens left in the
2559 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2561 2005-04-24 Paul D. Smith <psmith@gnu.org>
2563 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2564 with -l# can lose jobserver tokens, because waiting jobs are not
2565 consulted properly when checking for the "free" token.
2567 * job.c (free_child): Count waiting_jobs as having tokens.
2568 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2569 handle jobs waiting for the load to drop.
2571 2005-04-23 Paul D. Smith <psmith@gnu.org>
2573 * main.c (main): Be careful to not core if a variable setting in
2574 the environment doesn't contain an '='. This is illegal but can
2575 happen in broken setups.
2576 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2578 2005-04-12 Paul D. Smith <psmith@gnu.org>
2580 The second expansion feature causes significant slowdown. Timing
2581 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2582 read the makefile before the feature, to 11+s to do the same
2583 operations after the feature. Additionally, memory usage
2584 increased drastically. To fix this I added some intelligence that
2585 avoids the overhead of the second expansion unless it's required.
2587 * dep.h: Add a new boolean field, need_2nd_expansion.
2589 * read.c (eval): When creating the struct dep for the target,
2590 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2591 (record_files): If there's a "%" in a static pattern rule, it gets
2592 converted to "$*" so set need_2nd_expansion to 1.
2594 * file.c (expand_deps): Rework to be more efficient. Only perform
2595 initialize_file_variables(), set_file_variables(), and
2596 variable_expand_for_file() if the need_2nd_expansion is set.
2598 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2599 (pattern_search): Ditto.
2600 * main.c (handle_non_switch_argument): Ditto.
2602 * read.c (read_all_makefiles): Ditto.
2603 (eval_makefile): Ditto.
2605 2005-04-07 Paul D. Smith <psmith@gnu.org>
2607 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2608 * variable.c (sync_Path_environment): Ditto.
2609 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2611 * main.c (main): Define the .FEATURES variable.
2612 * NEWS: Announce .FEATURES.
2613 * doc/make.texi (Special Variables): Document .FEATURES.
2615 * remake.c (check_dep): If a file is .PHONY, update it even if
2616 it's marked intermediate. Fixes Savannah bug #12331.
2618 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2620 * file.c (expand_deps): Factor out the second expansion and
2621 prerequisite line parsing logic from snap_deps().
2623 * file.c (snap_deps): Use expand_deps(). Expand and parse
2624 prerequisites of the .SUFFIXES special target first. Fixes
2625 Savannah bug #12320.
2627 2005-03-13 Paul D. Smith <psmith@gnu.org>
2629 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2632 2005-03-11 Paul D. Smith <psmith@gnu.org>
2634 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2635 available, not undefined (from Earnie Boyd).
2637 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2639 * implicit.c (pattern_search): Mark an intermediate target as
2640 precious if it happened to be a prerequisite of some (other)
2641 target. Fixes Savannah bug #12267.
2643 2005-03-09 Paul D. Smith <psmith@gnu.org>
2645 * read.c (eval_makefile): Add alloca(0).
2646 (eval_buffer): Ditto.
2648 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2650 * main.c (main): Use o_file instead of o_default when defining
2651 the .DEFAULT_TARGET special variable.
2652 * read.c (eval): Use define_variable_global() instead of
2653 define_variable() when setting new value for the .DEFAULT_TARGET
2654 special variable. Fixes Savannah bug #12266.
2656 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2658 * imlicit.c (pattern_search): Mark files for which an implicit
2659 rule has been found as targets. Fixes Savannah bug #12202.
2661 2005-03-04 Paul D. Smith <psmith@gnu.org>
2664 * doc/make.texi (Automatic Variables): Document $|.
2666 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2668 * read.c (record_files): Instead of substituting % with
2669 actual stem value in dependency list replace it with $*.
2670 This fixes stem triple expansion bug.
2672 * implicit.c (pattern_search): Copy stem to a separate
2673 buffer and make it a properly terminated string. Assign
2674 this buffer instead of STEM (which is not terminated) to
2675 f->stem. Instead of substituting % with actual stem value
2676 in dependency list replace it with $*. This fixes stem
2677 triple expansion bug.
2679 2005-03-01 Paul D. Smith <psmith@gnu.org>
2681 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2682 on Windows, as it takes a handle not a pid. Just exit.
2683 Fix from patch #3679, provided by Alessandro Vesely.
2685 * configure.in: Update check for sys_siglist[] from autoconf manual.
2686 * signame.c (strsignal): Update to use the new autoconf macro.
2688 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2690 * read.c (record_files): Add a check for the list of prerequisites
2691 of a static pattern rule being empty. Fixes Savannah bug #12180.
2693 2005-02-28 Paul D. Smith <psmith@gnu.org>
2695 * doc/make.texi (Text Functions): Update docs to allow the end
2696 ordinal for $(wordlist ...) to be 0.
2697 * function.c (func_wordlist): Fail if the start ordinal for
2698 $(wordlist ...) is <1. Matches documentation.
2699 Resolves Savannah support request #103195.
2701 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2702 previously we were stopping when !-q, exactly the opposite. This
2703 has been wrong since version 1.34, in 1994!
2704 (update_file): If we got an error don't break out to run more
2705 double-colon rules: just return immediately.
2706 Fixes Savannah bug #7144.
2708 2005-02-27 Paul D. Smith <psmith@gnu.org>
2710 * misc.c (end_of_token): Make argument const.
2711 * make.h: Update prototype.
2713 * function.c (abspath, func_realpath, func_abspath): Use
2714 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2715 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2716 * read.c (record_files): Ditto.
2717 * variable.c (do_variable_definition): Ditto.
2719 * function.c (func_error): Create a new function $(info ...) that
2720 simply prints the message to stdout with no extras.
2721 (function_table_init): Add new function to the table.
2722 * NEWS: Add $(info ...) reference.
2723 * doc/make.texi (Make Control Functions): Document it.
2725 New feature: if the system supports symbolic links, and the user
2726 provides the -L/--check-symlink-time flag, then use the latest
2727 mtime between the symlink(s) and the target file.
2729 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2730 readlink(). If both are available, define MAKE_SYMLINKS.
2731 * main.c: New variable: check_symlink_flag.
2732 (usage): Add a line for -L/--check-symlink-times to the help string.
2733 (switches): Add -L/--check-symlink-times command line argument.
2734 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2735 print a warning and disable it again.
2736 * make.h: Declare check_symlink_flag.
2737 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2738 if the file is a symlink then check each link in the chain and
2739 choose the NEWEST mtime we find as the mtime for the file. The
2740 newest mtime might be the file itself!
2741 * NEWS: Add information about this new feature.
2742 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2744 Avoid core dumps described in Savannah bug # 12124:
2746 * file.c: New variable snapped_deps remember whether we've run
2748 (snap_deps): Set it.
2749 * filedef.h: Extern it.
2750 * read.c (record_files): Check snapped_deps; if it's set then
2751 we're trying to eval a new target/prerequisite relationship from
2752 within a command script, which we don't support. Fatal.
2754 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2756 Implementation of the .DEFAULT_TARGET special variable.
2758 * read.c (eval): If necessary, update default_target_name when
2760 * read.c (record_files): Update default_target_file if
2761 default_target_name has changed.
2762 * main.c (default_target_name): Define.
2763 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2764 default_target_name is set use default_target_file as a root
2766 * filedef.h (default_target_name): Declare.
2767 * dep.h (free_dep_chain):
2768 * misc.c (free_dep_chain): Change to operate on struct nameseq
2769 and change name to free_ns_chain.
2770 * file.c (snap_deps): Update to use free_ns_chain.
2772 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2774 Implementation of the second expansion in explicit rules,
2775 static pattern rules and implicit rules.
2777 * read.c (eval): Refrain from chopping up rule's dependencies.
2778 Store them in a struct dep as a single dependency line. Remove
2779 the code that implements SySV-style automatic variables.
2781 * read.c (record_files): Adjust the code that handles static
2782 pattern rules to expand all percents instead of only the first
2783 one. Reverse the order in which dependencies are stored so that
2784 when the second expansion reverses them again they appear in
2785 the makefile order (with some exceptions, see comments in
2786 the code). Remove the code that implements SySV-style automatic
2789 * file.c (snap_deps): Implement the second expansion and chopping
2790 of dependency lines for explicit rules.
2792 * implicit.c (struct idep): Define an auxiliary data type to hold
2793 implicit rule's dependencies after stem substitution and
2796 * implicit.c (free_idep_chain): Implement.
2798 * implicit.c (get_next_word): Implement helper function for
2799 parsing implicit rule's dependency lines into words taking
2800 into account variable expansion requests. Used in the stem
2803 * implicit.c (pattern_search): Implement the second expansion
2804 for implicit rules. Also fixes bug #12091.
2806 * commands.h (set_file_variables): Declare.
2807 * commands.c (set_file_variables): Remove static specifier.
2809 * dep.h (free_dep_chain): Declare.
2810 * misc.c (free_dep_chain): Implement.
2812 * variable.h (variable_expand_for_file): Declare.
2813 * expand.c (variable_expand_for_file): Remove static specifier.
2815 * make.h (strip_whitespace): Declare.
2816 * function.c (strip_whitespace): Remove static specifier.
2818 2005-02-26 Paul D. Smith <psmith@gnu.org>
2820 * main.c (main): Check for ferror() when reading makefiles from stdin.
2821 Apparently some shells in Windows don't close pipes properly and
2824 2005-02-24 Jonathan Grant <jg@jguk.org>
2826 * configure.in: Add MinGW configuration options, and extra w32 code
2828 * Makefile.am: Add MinGW configuration options, and extra w32 code
2830 * main.c: Determine correct program string (after last \ without .exe).
2831 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2833 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2834 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2835 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2836 environment support.
2838 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2840 * function.c (func_shell): When initializing error_prefix, check
2841 that reading file name is not null. This fixes long-standing
2842 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2844 2005-02-09 Paul D. Smith <psmith@gnu.org>
2846 * maintMakefile: Update the CVS download URL to simplify them.
2847 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2848 downloading the .texi files from Savannah now.
2850 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2852 * main.c (handle_non_switch_argument): Only add variables to
2853 command_variables if they're not already there: duplicate settings
2854 waste space and can be confusing to read.
2856 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2857 this header is never included by non-WINDOWS32 code, and it
2858 requires <config.h> to define which isn't always included first.
2860 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2861 testing MINGW32 versions.
2863 * main.c (log_working_directory): flush stdout to be sure the WD
2864 change is printed before any stderr messages show up.
2866 2005-02-01 Paul D. Smith <psmith@gnu.org>
2868 * maintMakefile (po_repo): Update the GNU translation site URL.
2870 2004-12-01 Paul D. Smith <psmith@gnu.org>
2872 * main.c (main): Change char* env_shell to struct variable shell_var.
2873 * variable.c (target_environment): Use new shell_var.
2875 2004-11-30 Paul D. Smith <psmith@gnu.org>
2877 * configure.in: The old way we avoided creating build.sh from
2878 build.sh.in before build.sh.in exists doesn't work anymore; we
2879 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2880 the help!). This also keeps automake from complaining.
2881 * Makefile.am (README): Add a dummy target so automake won't
2882 complain that this file doesn't exist when we checkout from CVS.
2883 * maintMakefile (.dep_segment): Rewrite this rule since newer
2884 versions of automake don't provide DEP_FILES.
2886 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2888 Implementation of `realpath' and `abspath' built-in functions.
2890 * configure.in: Check for realpath.
2891 * function.c (abspath): Return an absolute file name that does
2892 not contain any `.' or `..' components, nor repeated `/'.
2893 * function.c (func_abspath): For each name call abspath.
2894 * function.c (func_realpath): For each name call realpath
2895 from libc or delegate to abspath if realpath is not available.
2896 * doc/make.texi (Functions for File Names): Document new functions.
2897 * doc/make.texi (Quick Reference): Ditto.
2899 2004-11-28 Paul D. Smith <psmith@gnu.org>
2901 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2902 arguments. Fixes bug #10252.
2904 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2906 * main.c (main): Set SHELL to v_noexport by default. Remember the
2907 original environment setting of SHELL in the env_shell variable.
2908 * main.h: Export new env_shell variable.
2909 * variable.c (target_environment): If we find a v_noexport
2910 variable for SHELL, add a SHELL variable with the env_shell value.
2911 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2912 * doc/make.texi (Variables/Recursion): Ditto.
2914 2004-11-28 Paul D. Smith <psmith@gnu.org>
2916 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2917 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2918 Patch by Alessandro Vesely.
2920 2004-11-12 Paul D. Smith <psmith@gnu.org>
2922 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2923 the command line if it's inside a string.
2924 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2926 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2928 * function.c (func_lastword): New function: return last word
2929 from the list of words.
2930 * doc/make.texi: Document $(lastword ). Fix broken links in
2931 Quick Reference section.
2933 2004-10-06 Paul D. Smith <psmith@gnu.org>
2935 Apply patch from Alessandro Vesely, provided with bug # 9748.
2936 Fix use of tmpnam() to work with Borland C.
2938 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2939 construction of a temporary filename, and call new function
2940 create_batch_filename().
2941 (create_batch_filename) [WINDOWS32]: New function to create a
2944 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2946 * read.c (record_target_var): Expand simple pattern-specific
2948 * variable.c (initialize_file_variables): Do not expand simple
2949 pattern-specific variable.
2951 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2953 * remake.c (update_file_1): When rebuilding makefiles inherit
2954 dontcare flag from a target that triggered update.
2956 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2958 * variable.c (initialize_file_variables): Mark pattern-specific
2959 variable as a per-target and copy export status.
2961 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2963 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2965 * implicit.c (pattern_search): When considering an implicit rule's
2966 prerequisite check that it is actually a target rather then
2967 just an entry in the file hashtable.
2969 2004-09-21 Paul D. Smith <psmith@gnu.org>
2971 * read.c (readstring): Fix some logic errors in backslash handling.
2972 (eval): Remove some unnecessary processing in buffer handling.
2973 (record_target_var): Assert that parse_variable_definition() succeeded.
2974 Reported by: Markus Mauhart <qwe123@chello.at>.
2976 * misc.c: Removed the sindex() function. All instances of this
2977 function were trivially replaceable by the standard strstr()
2978 function, and that function will always have better (or certainly
2979 no worse) performance than the very simple-minded algorithm
2980 sindex() used. This can matter with complex makefiles.
2981 * make.h: Remove the prototype for sindex().
2982 * function.c (subst_expand): Convert sindex() call to strstr().
2983 This means we no longer need to track the TLEN value so remove that.
2984 (func_findstring): Convert sindex() to strstr().
2985 * commands.c (chop_commands): Convert sindex() calls to strstr().
2986 Suggested by: Markus Mauhart <qwe123@chello.at>.
2988 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2989 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2990 If SHELL is set to CMD.EXE then assume it's batch-mode and
2991 non-unixy. I wrote the code differently from the patch, though,
2992 to make it safer. This also resolves bug #9174.
2994 2004-09-20 Paul D. Smith <psmith@gnu.org>
2996 * expand.c (variable_expand_string): Modify to invoke
2997 patsubst_expand() instead of subst_expand(); the latter didn't
2998 handle suffix patterns correctly.
2999 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
3000 was used only from variable_expand_string() and is no longer used
3002 (func_subst): Ditto, on call to subst_expand().
3003 (patsubst_expand): Require the percent pointers to point to the
3004 character after the %, not to the % itself.
3005 * read.c (record_files): New call criteria for patsubst_expand().
3006 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
3007 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
3009 2004-09-19 Paul D. Smith <psmith@gnu.org>
3011 * function.c (subst_expand): Fix a check in by_word: look for a
3012 previous blank if we're beyond the beginning of the string, not
3013 the beginning of the word.
3014 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3016 2004-05-16 Paul D. Smith <psmith@gnu.org>
3018 * remake.c (update_goal_chain): Change the argument specifying
3019 whether we're rebuilding makefiles to be a global variable,
3020 REBUILDING_MAKEFILES.
3021 (complain): Extract the code that complains about no rules to make
3022 a target into a separate function.
3023 (update_file_1): If we tried to rebuild a file during the makefile
3024 rebuild phase and it was dontcare, then no message was printed.
3025 If we then try to build the same file during the normal build,
3026 print a message this time.
3027 (remake_file): Don't complain about un-remake-able files when
3028 we're rebuilding makefiles.
3030 2004-05-11 Paul D. Smith <psmith@gnu.org>
3032 * job.c (construct_command_argv_internal): OS/2 patches from
3033 Andreas Buening <andreas.buening@nexgo.de>.
3035 2004-05-10 Paul D. Smith <psmith@gnu.org>
3037 * remake.c (update_file): Don't walk the double-colon chain unless
3038 this is a double-colon rule. Fix suggested by Boris Kolpackov
3039 <boris@kolpackov.net>.
3041 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3042 * readme.vms: New section describing OpenVMS support and issues.
3043 * default.c (default_variables): Add support for IA64.
3044 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3045 without some privilege aborts make with the error
3046 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3047 pressing Ctrl+Y and the input device is no terminal. The change
3048 catches this error and just continues.
3050 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3052 2004-04-25 Paul D. Smith <psmith@gnu.org>
3054 * commands.c (set_file_variables): Set $< properly in the face of
3055 order-only prerequisites.
3056 Patch from Boris Kolpackov <boris@kolpackov.net>
3058 2004-04-21 Bob Byrnes <byrnes@curl.com>
3060 * main.c (main): Notice failures to remake makefiles.
3062 2004-03-28 Paul D. Smith <psmith@gnu.org>
3064 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3066 * job.c: No default shell for RISC OS.
3067 (load_too_high): Hard-code the return to 1.
3068 (construct_command_argv_internal): No sh_chars or sh_cmds.
3069 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3071 2004-03-20 Paul D. Smith <psmith@gnu.org>
3073 * variable.c (do_variable_definition): Don't append from the
3074 global set if a previous non-appending target-specific variable
3075 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3078 * expand.c (reference_variable): Don't give up on variables with
3079 no value that have the target-specific append flag set: they might
3080 have a value after all. Reported by Oliver Schmidt
3081 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3082 <nikulin@dx1cmd.inp.nsk.su>.
3084 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3085 refer to absolute pathnames in directories that don't exist: some
3086 portion of the makefile could create those directories before we
3087 match the pattern. Fixes bugs #775 and #108.
3089 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3091 * main.c (main): Free makefile_mtimes if we have any.
3092 * README.W32.template: Update documentation for the current status
3093 of the MS-Windows port.
3094 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3095 environment variable is sometimes already defined which causes the
3097 * main.c (debug_signal_handler): Only define this function if
3098 SIGUSR1 is available.
3100 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3102 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3103 * README.OS2.template: Documentation updates.
3104 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3105 link line for safety.
3106 * maintMakefile (build.sh.in): Remove an extraneous ")".
3107 * job.c (child_execute_job): Close saved FDs.
3108 * job.c (exec_command) [OS/2]: exec_command(): If the command
3109 can't be exec'ed and if the shell is not Unix-sh, then try again
3110 with argv = { "cmd", "/c", ... }. Normally, this code is never
3111 reached for the cmd shell unless the command really doesn't exist.
3112 (construct_command_argv_internal) [OS/2]: The code for cmd
3113 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3114 The CMD builtin commands are case insensitive so use strcasecmp().
3116 2004-03-19 Paul D. Smith <psmith@gnu.org>
3118 * read.c (do_define): Re-order line counter increment so the count
3119 is accurate (we were losing one line per define). Reported by
3120 Dave Yost <Dave@Yost.com>.
3122 2004-03-06 Paul D. Smith <psmith@gnu.org>
3124 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3126 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3127 * misc.c (message,error,fatal): Ditto.
3128 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3129 * config.h.W32.template: Ditto.
3130 * config.h-vms.template: Ditto.
3131 * config.ami.template: Ditto.
3133 2004-03-04 Paul D. Smith <psmith@gnu.org>
3135 * README.template: Add a note about broken /bin/sh on SunOS
3136 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3138 * misc.c (message, error, fatal): Don't use "..." if we're using
3139 varargs. ansi2knr should handle this but it doesn't work: it
3140 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3141 done. On many systems (SunOS for example) va_dcl is a #define.
3142 So, force the use of the non-"..." version on pre-ANSI compilers.
3144 * maintMakefile (sign-dist): Create some rules to help automate
3145 the new GNU ftp upload method.
3147 2004-02-24 Paul D. Smith <psmith@gnu.org>
3149 * config.h.W32.template: Add HAVE_STDARG_H
3150 * config.h-vms.template: Ditto.
3151 * config.ami.template: Ditto.
3153 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3155 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3156 * build_w32.bat: Remove extra "+".
3158 2004-02-23 Paul D. Smith <psmith@gnu.org>
3160 * make.h: Create an UNUSED macro to mark unused parameters.
3161 * (many): Clean up warnings by applying UNUSED, fixing
3162 signed/unsigned incompatibilities, etc.
3164 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3166 * filedef.h: Name the command_state enumeration.
3167 * file.c (set_command_state): Use the enumeration in the function
3170 * configure.in: Explicitly set SET_MAKE to empty, to disable
3171 MAKE=make even when no make already exists. Fix bug #3823.
3173 2004-02-22 Paul D. Smith <psmith@gnu.org>
3175 * maintMakefile: Perl script to clean up all non-CVS files. Use
3176 it on all the subdirectories for the cvs-clean target.
3178 * main.c (decode_switches): Require non-empty strings for all our
3179 string command-line options. Fixes Debian bug # 164165.
3181 * configure.in: Check for stdarg.h and varargs.h.
3182 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3183 for printing messages.
3184 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3189 A number of patches for OS/2 support from Andreas Buening
3190 <andreas.buening@nexgo.de>:
3192 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3193 disable the SIGCHLD handler.
3194 (reap_children) [OS/2]: Remove special handling of job_rfd.
3195 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3196 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3197 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3198 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3199 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3202 2004-02-21 Paul D. Smith <psmith@gnu.org>
3204 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3205 <mail@kristov.de> reports that if process_begin() fails we don't
3206 handle the error condition correctly in all cases.
3207 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3208 to have a newline on the message.
3210 * job.c (construct_command_argv_internal): Add "test" to UNIX
3211 sh_cmds[]. Fixes Savannah bug # 7606.
3213 2004-02-04 Paul D. Smith <psmith@gnu.org>
3215 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3216 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3217 Hartmut Becker <Hartmut.Becker@hp.com>.
3219 2004-01-21 Paul D. Smith <psmith@gnu.org>
3221 * job.c (load_too_high): Implement an algorithm to control the
3222 "thundering herd" problem when using -l to control job creation
3223 via the load average. The system only recomputes the load once a
3224 second but we can start many jobs in a second. To solve this we
3225 keep track of the number of jobs started in the last second and
3226 apply a weight to try to guess what a correct load would be.
3227 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3228 Also fixes bug #4693.
3229 (reap_children): Decrease the job count for this second.
3230 (start_job_command): Increase the job count for this second.
3232 * read.c (conditional_line): Expand the text after ifn?def before
3233 checking to see if it's a single word. Fixes bug #7257.
3235 2004-01-09 Paul D. Smith <psmith@gnu.org>
3237 * file.c (print_file): Recurse to print all targets in
3238 double-colon rules. Fixes bug #4518, reported (with patch) by
3239 Andrew Chatham <chatham@google.com>.
3241 2004-01-07 Paul D. Smith <psmith@gnu.org>
3243 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3244 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3245 AC_FUNC_SETVBUF_REVERSED.
3247 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3248 (MAKE Variable): Fix Savannah bug #4898.
3250 * job.c (construct_command_argv_internal): Add "!" to the list of
3251 shell escape chars. POSIX sh allows it to appear before a
3252 command, to negate the exit code. Fixes bug #6404.
3254 * implicit.c (pattern_search): When matching an implicit rule,
3255 remember which dependencies have the ignore_mtime flag set.
3256 Original fix provided in Savannah patch #2349, by Benoit
3257 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3259 2003-11-22 Paul D. Smith <psmith@gnu.org>
3261 * README.W32.template (Outputs): Clarification on -j with
3262 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3265 2003-11-02 Paul D. Smith <psmith@gnu.org>
3267 * function.c (func_if): Strip all the trailing whitespace from the
3268 condition, then don't expand it. Fixed bug # 5798.
3270 * expand.c (recursively_expand_for_file): If we're expanding a
3271 variable with no file context, then use the variable's context.
3274 2003-10-21 Paul D. Smith <psmith@gnu.org>
3276 * main.c (log_working_directory): Add newlines to printf()s.
3278 * README.cvs: Add a note to ignore warnings during autoreconf.
3280 * maintMakefile (po_repo): Set a new URL for PO file updates.
3281 (get-config/config.guess get-config/config.sub): Get these files
3282 from the Savannah config project instead of ftp.gnu.org.
3284 2003-10-05 Paul Eggert <eggert@twinsun.com>
3286 * main.c (main): Avoid potential subscript error if environ has
3289 2003-08-22 Paul D. Smith <psmith@gnu.org>
3291 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3292 systems which don't yet implement the C89 standard :-/.
3294 2003-07-18 Paul D. Smith <psmith@gnu.org>
3296 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3297 [WINDOWS32]: Initialize hash.
3299 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3301 * dir.c (read_dirstream): Provide a workaround for broken versions of
3302 the MinGW dirent structure.
3304 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3306 * w32/include/dirent.h: Add __MINGW32__ filter.
3308 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3310 * make.h: Add global declaration of *make_host.
3311 * main.c (print_usage): Remove local declaration of *make_host.
3312 (print_version): Display "This program built for ..." after Copyright
3315 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3317 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3318 execution of "makeinfo --html make.texi".
3320 2003-04-30 Paul D. Smith <psmith@gnu.org>
3322 * build.template: Make some changes to maybe allow this script to
3323 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3325 * README.OS2.template: New file for OS/2 support. Original
3326 contributed by Andreas Buening.
3327 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3330 2003-04-19 Paul D. Smith <psmith@gnu.org>
3332 Fix bug #1405: allow a target to match multiple pattern-specific
3335 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3336 variable.c, where they've always belonged.
3337 * rule.h: Move the prototypes and struct pattern_var as well.
3338 * variable.c (initialize_file_variables): Invoke
3339 lookup_pattern_var() in a loop, until no more matches are found.
3340 If a match is found, create a new variable set for the target's
3341 pattern variables. Then merge the contents of each matching
3342 pattern variable set into the target's pattern variable set.
3343 (lookup_pattern_var): Change this function to be usable
3344 in a loop. It takes a starting position: if NULL, start at the
3345 beginning; if non-NULL, start with the pattern variable after that
3346 position, and return the next matching pattern.
3347 (create_pattern_var): Create a unique instance of
3348 pattern-specific variables for every definition in the makefile.
3349 Don't combine the same pattern together. This allows us to
3350 process the variable handling properly even when the same pattern
3351 is used multiple times.
3352 (parse_variable_definition): New function: break out the parsing
3353 of a variable definition line from try_variable_definition.
3354 (try_variable_definition): Call parse_variable_definition to
3356 (print_variable_data_base): Print out pattern-specific variables.
3357 * variable.h (struct variable): Remember when a variable is
3358 conditional. Also remember its flavor.
3359 (struct pattern_var): Instead of keeping a variable set, we just
3360 keep a single variable for each pattern.
3361 * read.c (record_target_var): Each pattern variable contains only a
3362 single variable, not a set, so create it properly.
3363 * doc/make.texi (Pattern-specific): Document the new behavior.
3365 2003-04-17 Paul D. Smith <psmith@gnu.org>
3367 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3368 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3369 file/directory naming rules for VMS so I can't tell whether this
3372 2003-04-09 Paul D. Smith <psmith@gnu.org>
3374 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3375 DOS-style pathnames: backslash separators and drive specifiers.
3377 2003-03-28 Paul D. Smith <psmith@gnu.org>
3379 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3380 the intermediate flag on all targets. Fixes bug #2515.
3382 2003-03-24 Paul D. Smith <psmith@gnu.org>
3384 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3385 Upgrade to autoconf 2.57 and automake 1.7.3.
3387 * job.c: More OS/2 changes from Andreas Buening.
3389 * file.c (print_file): Fix variable initialization.
3392 * remake.c (notice_finished_file):
3394 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3395 some calls (like readdir()) return NULL in valid situations
3396 without resetting errno. Fixes bug #2846.
3398 2003-02-25 Paul D. Smith <psmith@gnu.org>
3400 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3402 * job.c (_is_unixy_shell) [OS/2]: New function.
3403 Set default shell to /bin/sh.
3404 (reap_children): Close the job_rfd pipe here since we don't use a
3406 (set_child_handler_action_flags): define this to empty on OS/2.
3407 (start_job_command): Close the jobserver pipe and use
3408 child_execute_job() instead of fork/exec.
3409 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3410 rather than exec'ing, then reconfigure stdin/stdout.
3411 (exec_command): Rewrite to use spawn instead of exec. Return the
3414 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3415 in DOS. Handle the TEMP environment variable as in DOS. Don't
3416 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3417 use -j in DOS mode. Use child_execute_job() instead of
3420 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3423 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3424 prototypes that return values.
3426 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3428 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3429 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3431 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3434 2003-02-24 Paul D. Smith <psmith@gnu.org>
3436 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3437 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3438 (child_execute_job) [VMS]: Handle error status properly.
3439 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3441 * function.c (func_shell): Use EINTRLOOP() while reading from the
3442 subshell pipe (Fixes bug #2502).
3443 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3445 * main.c (main): Ditto.
3447 2003-01-30 Paul D. Smith <psmith@gnu.org>
3449 * read.c (eval): eval() was not fully reentrant, because the
3450 collapsed buffer was static. Change it to be an automatic
3451 variable so that eval() can be invoked recursively.
3453 (eval): Apply patch # 1022: fix memory reference error on long
3454 target-specific variable lines.
3455 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3457 * function.c (check_numeric): Combine the is_numeric() function
3458 into this function, since it's only called from one place.
3459 Constify this function. Have it print the incorrect string in the
3460 error message. Fixes bug #2407.
3461 (strip_whitespace): Constify.
3462 (func_if): Constify.
3463 * expand.c (expand_argument): Constify.
3465 2003-01-29 Paul D. Smith <psmith@gnu.org>
3467 Fix bug # 2169, also reported by other people on various systems.
3469 * make.h: Some systems, such as Solaris and PTX, do not fully
3470 implement POSIX-compliant SA_RESTART functionality; important
3471 system calls like stat() and readdir() can still fail with EINTR
3472 even if SA_RESTART has been set on the signal handler. So,
3473 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3474 EINTR for system calls which return -1 or 0 (NULL), respectively,
3476 Also, remove the old atomic_stat()/atomic_readdir() and
3477 HAVE_BROKEN_RESTART handling.
3479 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3481 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3482 * remake.c (touch_file): Ditto.
3484 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3485 * read.c (construct_include_path): Ditto.
3486 * remake.c (name_mtime): Ditto.
3487 * vpath.c (selective_vpath_search): Ditto.
3488 * dir.c (find_directory): Ditto.
3489 (local_stat): Ditto.
3490 (find_directory): Use ENULLLOOP() to wrap opendir().
3491 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3493 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3494 atomic_readdir() handling.
3496 2003-01-22 Paul D. Smith <psmith@gnu.org>
3498 * function.c (func_call): Fix Bug #1744. If we're inside a
3499 recursive invocation of $(call ...), mask any of the outer
3500 invocation's arguments that aren't used by this one, so that this
3501 invocation doesn't "inherit" them accidentally.
3503 2002-12-05 Paul D. Smith <psmith@gnu.org>
3505 * function.c (subst_expand): Valery Khamenia reported a
3506 pathological performance hit when doing substitutions on very
3507 large values with lots of words: turns out we were invoking
3508 strlen() a ridiculous number of times. Instead of having each
3509 call to sindex() call strlen() again, keep track of how much of
3510 the text we've seen and pass the length to sindex().
3512 2002-11-19 Paul D. Smith <psmith@gnu.org>
3514 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3517 2002-11-16 Paul D. Smith <psmith@gnu.org>
3519 * NMakefile.template (OBJS): Add hash.c object file.
3520 * SMakefile.template (srcs): Ditto.
3521 * Makefile.ami (objs): Ditto.
3522 * build_w32.bat: Ditto.
3524 * Makefile.DOS.template: Remove extra dependencies.
3526 2002-10-25 Paul D. Smith <psmith@gnu.org>
3528 * expand.c (install_variable_buffer): New function. Install a new
3529 variable_buffer context and return the previous one.
3530 (restore_variable_buffer): New function. Free the current
3531 variable_buffer context and put a previously saved one back.
3532 * variable.h: Prototypes for {install,restore}_variable_buffer.
3533 * function.c (func_eval): Push a new variable_buffer context
3534 before we eval, then restore the old one when we're done.
3537 * read.c (install_conditionals): New function. Install a new
3538 conditional context and return the previous one.
3539 (restore_conditionals): New function. Free the current
3540 conditional context and put a previously saved one back.
3541 (eval): Use the {install,restore}_conditionals for "include"
3543 (eval_buffer): Use {install,restore}_conditionals to preserve the
3544 present conditional state before we evaluate the buffer.
3547 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3549 (Recursion): Add a variable index entry for CURDIR.
3551 * README.cvs: Update to appropriate versions.
3552 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3553 don't need to copy loadavg.c: automake is smart enough to create
3554 it for me. Still have a bug in automake related to ansi2knr tho.
3556 2002-10-14 Paul D. Smith <psmith@gnu.org>
3558 * remake.c (notice_finished_file): Only touch targets if they have
3559 at least one command (as per POSIX). Resolve Bug #1418.
3561 * *.c: Convert to using ANSI C-style function definitions.
3562 * Makefile.am: Enable the ansi2knr feature of automake.
3563 * configure.in: ditto.
3565 2002-10-13 Paul D. Smith <psmith@gnu.org>
3567 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3568 for automatic variable values like $^, etc. In the case of very
3569 large lists of prerequisites this causes problems. Instead reuse
3570 a static buffer (resizeable) for each variable.
3572 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3573 target-specific variable definitions. Check for it and set an
3575 (record_target_var): Set the export field to v_export if the
3576 "exported" flag is set.
3577 * doc/make.texi (Target-specific): Document the ability to use
3580 * doc/make.texi: Change the name of the section on automatic
3581 variables from "Automatic" to "Automatic Variables". Added text
3582 clarifying the scope of automatic variables.
3584 2002-10-04 Paul D. Smith <psmith@gnu.org>
3586 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3588 (record_files): Ditto.
3590 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3591 the search for the '=' to only within the enclosing parens.
3593 2002-10-03 Paul D. Smith <psmith@gnu.org>
3595 Version 3.80 released.
3597 * dir.c: Change hash functions to use K&R function definition style.
3598 * function.c: Ditto.
3600 * variable.c: Ditto.
3602 Update to automake 1.7.
3604 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3605 (pdf): Remove this target as automake now provides one.
3607 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3609 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3611 * makefile.com: Updates for GNU make 3.80.
3612 * makefile.vms: Ditto.
3614 2002-09-23 Paul D. Smith <psmith@gnu.org>
3616 * read.c (enum make_word_type): Remove w_comment.
3617 (get_next_mword): Don't treat comment characters as special; where
3618 this function is used we will never see a comment (it's stripped
3619 before we get here) and treating comments specially means that
3620 targets like "foo\#bar" aren't handled properly.
3622 2002-09-18 Paul D. Smith <psmith@gnu.org>
3624 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3626 * read.c (eval): Expansion of arguments to export/unexport was
3627 ignoring all arguments after the first one. Change the algorithm
3628 to expand the whole line once, then parse the results.
3630 2002-09-17 Paul D. Smith <psmith@gnu.org>
3632 Fix Bug #940 (plus another bug I found while looking at this):
3634 * read.c (record_target_var): enter_file() will add a new entry if
3635 it's a double-colon target: we don't want to do that in this
3636 situation. Invoke lookup_file() and only enter_file() if it does
3637 not already exist. If the file we get back is a double-colon then
3638 add this variable to the "root" double-colon target.
3640 * variable.c (initialize_file_variables): If this file is a
3641 double-colon target but is not the "root" target, then initialize
3642 the root and make the root's variable list the parent of our
3645 2002-09-13 Paul D. Smith <psmith@gnu.org>
3647 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3649 * hash.c (round_up_2): Get rid of a warning.
3651 2002-09-12 Paul D. Smith <psmith@gnu.org>
3653 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3654 so it doesn't complain about getloadavg.c.
3656 * commands.c (set_file_variables): Make sure we always alloca() at
3657 least 1 character for the value of $? (for '\0').
3659 2002-09-11 Paul D. Smith <psmith@gnu.org>
3661 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3662 macro to use RESULT instead of the incorrect _RESULT_.
3664 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3665 and atomic_readdir(). We need to #include dirent.h to get this to
3667 * misc.c (atomic_readdir): Fix typos.
3669 2002-09-10 Paul D. Smith <psmith@gnu.org>
3671 * read.c (eval): Expand variable lists given to export and
3672 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3673 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3675 * doc/make.texi (Variables/Recursion): Document this.
3676 (Conditional Syntax): And here.
3678 2002-09-09 Paul D. Smith <psmith@gnu.org>
3680 * configure.in: Check for memmove().
3682 2002-09-07 Paul D. Smith <psmith@gnu.org>
3684 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3685 Michael Sterrett <msterret@coat.com> reports that while it has
3686 SA_RESTART, it does not work properly.
3688 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3689 that invokes stat() and loops to do it again if it returns EINTR.
3690 (atomic_readdir): Ditto, with readdir().
3692 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3693 and readdir() to atomic_stat() and atomic_readdir().
3695 2002-09-04 Paul D. Smith <psmith@gnu.org>
3697 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3698 reports that GNU make sometimes doesn't recognize that targets can
3699 be made, when directories can be created as prerequisites. He
3700 reports that changing the order of predicates in the DEP->changed
3701 flag test so that lookup_file() is always performed, solves this
3704 2002-08-08 Paul D. Smith <psmith@gnu.org>
3706 * configure.in: Require a newer version of gettext.
3708 * misc.c (perror_with_name): Translate the format string (for
3709 right-to-left language support).
3710 (pfatal_with_name): Ditto.
3712 * main.c: Create a static array of strings to store the usage
3713 text. This is done to facilitate translations.
3714 (struct command_switch): Remove argdesc and description fields.
3715 (switches): Remove values for obsolete fields.
3716 (print_usage): Print each element of the usage array.
3718 * hash.c: Change function definitions to be K&R style.
3720 2002-08-02 Paul D. Smith <psmith@gnu.org>
3722 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3723 this one because it's too hard to get right. We'll look at it for
3725 * main.c (main): Don't create the .TARGETS variable.
3726 * variable.c (handle_special_var): Don't handle .TARGETS.
3728 2002-08-01 Paul D. Smith <psmith@gnu.org>
3730 * main.c (switches): Add a new option, -B (--always-make). If
3731 specified, make will rebuild all targets that it encounters even
3732 if they don't appear to be out of date.
3733 (always_make_flag): New flag.
3734 * make.h: Extern always_make_flag.
3735 * remake.c (update_file_1): Check always_make_flag; if it's set we
3736 will always rebuild any target we can, even if none of its
3737 prerequisites are newer.
3740 * doc/make.texi (Shell Function): Make it clear that make
3741 variables marked as "export" are not passed to instances of the
3744 Add new introspection variable .VARIABLES and .TARGETS.
3746 * variable.c (handle_special_var): New function. If the variable
3747 reference passed in is "special" (.VARIABLES or .TARGETS),
3748 calculate the new value if necessary. .VARIABLES is handled here:
3749 walk through the hash of defined variables and construct a value
3750 which is a list of the names. .TARGETS is handled by
3751 build_target_list().
3752 (lookup_variable): Invoke handle_special_var().
3753 * file.c (build_target_list): Walk through the hask of known files
3754 and construct a list of the names of all the ones marked as
3756 * main.c (main): Initialize them to empty (and as simple variables).
3757 * doc/make.texi (Special Variables): Document them.
3758 * NEWS: Mention them.
3760 * variable.h (struct variable): Add a new flag "exportable" which
3761 is true if the variable name is valid for export.
3762 * variable.c (define_variable_in_set): Set "exportable" when a new
3763 variable is defined.
3764 (target_environment): Use the "exportable" flag instead of
3765 re-checking the name here... an efficiency improvement.
3767 2002-07-31 Paul D. Smith <psmith@gnu.org>
3769 * config.h-vms.template: Updates to build on VMS. Thanks to
3770 Brian_Benning@aksteel.com for helping verify the build.
3771 * makefile.com: Build the new hash.c file.
3772 * hash.h: Use strcpmi(), not stricmp(), in the
3773 HAVE_CASE_INSENSITIVE_FS case.
3775 2002-07-30 Paul D. Smith <psmith@gnu.org>
3777 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3778 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3779 Reported by <Brian_Benning@aksteel.com>.
3781 2002-07-10 Paul D. Smith <psmith@gnu.org>
3783 * variable.c (pop_variable_scope): Remove variable made unused by
3784 new hash infrastructure.
3785 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3786 comparisons as well as name comparisons.
3787 * variable.h: Add a prototype for new hash_init_function_table().
3788 * file.c (lookup_file): Remove variables made unused by new hash
3790 * dir.c (directory_contents_hash_2): Missing return of hash value.
3791 (dir_contents_file_exists_p): Remove variables made unused by new
3792 hash infrastructure.
3795 Installed Greg McGary's integration of the hash functions from the
3796 GNU id-utils package:
3798 2002-07-10 Greg McGary <greg@mcgary.org>
3800 * scripts/functions/filter-out: Add literals to to the
3801 pattern space in order to add complexity, and trigger
3802 use of an internal hash table. Fix documentation strings.
3803 * scripts/targets/INTERMEDIATE: Reverse order of files
3804 passed to expected `rm' command.
3806 2002-07-10 Greg McGary <greg@mcgary.org>

3898 2002-07-10 Paul D. Smith <psmith@gnu.org>
3900 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3901 prerequisite list. A real SysV make will expand the entire
3902 prerequisites list _twice_: we don't do that as it's a big
3903 backward-compatibility problem. We only replace those specific
3906 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3907 references left in the list of prerequisites. Check for .POSIX as
3908 we record targets, so we can disable non-POSIX behavior while
3909 reading makefiles as well as running them.
3910 (eval): Check the prerequisite list to see if we have anything
3911 that looks like a SysV prerequisite variable reference.
3913 2002-07-09 Paul D. Smith <psmith@gnu.org>
3915 * doc/make.texi (Prerequisite Types): Add a new section describing
3916 order-only prerequisites.
3918 * read.c (uniquize_deps): If we have the same file as both a
3919 normal and order-only prereq, get rid of the order-only prereq,
3920 since the normal one supersedes it.
3922 2002-07-08 Paul D. Smith <psmith@gnu.org>
3924 * AUTHORS: Added Greg McGary to the AUTHORS file.
3925 * NEWS: Blurbed order-only prerequisites.
3926 * file.c (print_file): Show order-only deps properly when printing
3929 * maintMakefile: Add "update" targets for wget'ing the latest
3930 versions of various external files. Taken from Makefile.maint in
3933 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3934 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3936 2002-07-07 Paul D. Smith <psmith@gnu.org>
3938 * po/*.po: Remove. We'll use wget to retrieve them at release
3941 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3942 rather than a shell you get an exception. Make sure we look up
3943 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3945 * remake.c (notice_finished_file): Fix handling of -t flag.
3946 Patch provided by Henning Makholm <henning@makholm.net>.
3948 * implicit.c (pattern_search): Some systems apparently run short
3949 of stack space, and using alloca() in this function caused an
3950 overrun. I modified it to use xmalloc() on the two variables
3951 which seemed like they might get large. Fixes Bug #476.
3953 * main.c (print_version): Update copyright notice to conform with
3955 (print_usage): Update help output.
3957 * function.c (func_eval): Create a new make function, $(eval
3958 ...). Expand the arguments, put them into a buffer, then invoke
3959 eval_buffer() on the resulting string.
3960 (func_quote): Create a new function, $(quote VARNAME). Inserts
3961 the value of the variable VARNAME without expanding it any
3964 * read.c (struct ebuffer): Change the linebuffer structure to an
3965 "eval buffer", which can be either a file or a buffer.
3966 (eval_makefile): Move the code in the old read_makefile() which
3967 located a makefile into here: create a struct ebuffer with that
3968 information. Have it invoke the new function eval() with that
3970 (eval_buffer): Create a new function that creates a struct ebuffer
3971 that holds a string buffer instead of a file. Have it invoke
3972 eval() with that ebuffer.
3973 (eval): New function that contains the guts of the old
3974 read_makefile() function: this function parses makefiles. Obtains
3975 data to parse from the provided ebuffer. Some modifications to
3976 make the flow of the function cleaner and clearer. Still could
3977 use some work here...
3978 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3979 contents of the define/endef variable from the ebuffer.
3980 (readstring): Read the next line from a string-style ebuffer.
3981 (readline): Read the next line from an ebuffer. If it's a string
3982 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3985 * dep.h (eval_buffer): Prototype eval_buffer();
3987 * variable.c (do_variable_definition): Make sure that all
3988 non-target-specific variables are registered in the global set.
3989 If we're invoked from an $(eval ...) we might be inside a $(call
3990 ...) or other function which has pushed a variable scope; we still
3991 want to define our variables from evaluated makefile code in the
3994 2002-07-03 Greg McGary <greg@mcgary.org>
3996 * dep.h (struct dep) [ignore_mtime]: New member.
3997 [changed]: convert to a bitfield.
3998 * implicit.c (pattern_search): Zero ignore_mtime.
3999 * main.c (main, handle_non_switch_argument): Likewise.
4000 * rule.c (convert_suffix_rule): Likewise.
4001 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
4002 (read_makefile): Parse '|' in prerequisite list.
4003 (uniquize_deps): Consider ignore_mtime when comparing deps.
4004 * remake.c (update_file_1, check_dep): Don't force remake for
4005 dependencies that have d->ignore_mtime.
4006 * commands.c (FILE_LIST_SEPARATOR): New constant.
4007 (set_file_variables): Don't include a
4008 prerequisite in $+, $^ or $? if d->ignore_mtime.
4011 2002-06-18 Paul D. Smith <psmith@gnu.org>
4013 * make.texinfo: Updates for next revision. New date/rev/etc.
4014 Recreate all Info menus. Change license on the manual to the GNU
4015 Free Documentation License. A number of typos.
4016 (Variables Simplify): Don't use "-" before it's defined.
4017 (Automatic Prerequisites): Rewrite the target example to work
4018 properly if the compile fails. Remove incorrect comments about
4019 how "set -e" behaves.
4020 (Text Functions): Move the "word", "wordlist", "words", and
4021 "firstword" functions here, from "File Name Functions".
4022 * make-stds.texi: Update from latest GNU version.
4023 * fdl.texi: (created) Import the latest GNU version.
4025 2002-06-06 Paul D. Smith <psmith@gnu.org>
4027 * variable.c (do_variable_definition): New function: extract the
4028 part of try_variable_definition() that actually sets the value
4029 into a separate function.
4030 (try_variable_definition): Call do_variable_definition() after
4031 parsing the variable definition string.
4032 (define_variable_in_set): Make the name argument const.
4034 * variable.h (enum variable_flavor): Make public.
4035 (do_variable_definition): Create prototype.
4037 * read.c (read_all_makefiles): Create a new built-in variable,
4039 (read_makefile): Add each makefile read in to this variable value.
4041 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4043 * Makefile.DOS.template: Tweak according to changes in the
4044 distribution. Add back the dependencies of *.o files.
4046 * configh.dos.template: Synchronize with config.h.in.
4048 2002-05-09 Paul D. Smith <psmith@gnu.org>
4050 * file.c (file_timestamp_now): Use K&R function declaration.
4052 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4053 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4054 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4055 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4056 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4057 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4058 nlist.n_name is a pointer rather than an array.
4060 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4061 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4062 * configure.in: Use it instead of the old version.
4064 * main.c (main): Prefer setvbuf() to setlinebuf().
4066 2002-05-08 Paul D. Smith <psmith@gnu.org>
4068 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4069 (loadavg_LDADD): Ditto.
4071 2002-04-29 Paul D. Smith <psmith@gnu.org>
4073 * expand.c (recursively_expand_for_file): Rename
4074 recursively_expand() to recursively_expand_for_file() and provide
4075 an extra argument, struct file. If the argument is provided, set
4076 the variable scope to that of the file before expanding.
4077 * variable.h (recursively_expand): Make this a macro that invokes
4078 recursively_expand_for_file() with a NULL file pointer.
4079 * variable.c (target_environment): Call the renamed function and
4080 provide the current file context.
4081 Fixes Debian bug #144306.
4083 2002-04-28 Paul D. Smith <psmith@gnu.org>
4085 Allow $(call ...) user-defined variables to be self-referencing
4086 without throwing an error. Allows implementation of transitive
4087 closures, among other possibly useful things.
4088 Requested by: Philip Guenther <guenther@sendmail.com>
4090 * variable.h (struct variable): Add a new field: exp_count, and
4091 new macros to hold its size and maximum value.
4092 (warn_undefined): Make this a macro.
4093 * variable.c (define_variable_in_set): Initialize it.
4094 * expand.c (recursively_expand): If we detect recursive expansion
4095 of a variable, check the exp_count field. If it's greater than 0
4096 allow the recursion and decrement the count.
4097 (warn_undefined): Remove this (now a macro in variable.h).
4098 * function.c (func_call): Before we expand the user-defined
4099 function, modify its exp_count field to contain the maximum
4100 number of recursive calls we'll allow. After the call, reset it
4103 2002-04-21 Paul D. Smith <psmith@gnu.org>
4105 Modified to use latest autoconf (2.53), automake (1.6.1), and
4106 gettext (0.11.1). We're using gettext's new "external" support,
4107 to avoid including libintl source with GNU make.
4109 * README.cvs: New file. Explain how to build GNU make from CVS.
4111 * configure.in: Modify checking for the system glob library.
4112 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4113 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4114 etc. will manage it correctly). Set an automake conditional
4115 USE_LOCAL_GLOB to decide whether to compile the glob library.
4117 * getloadavg.c (main): Include make.h in the "TEST" program to
4120 * Makefile.am: Remove special rules for loadavg. Replace them
4121 with Automake capabilities for building extra programs.
4123 * signame.c: This file does nothing if the system provide
4124 strsignal(). If not, it implements strsignal(). If the system
4125 doesn't define sys_siglist, then we make our own; otherwise we use
4127 * signame.h: Removed.
4129 * main.c (main): No need to invoke signame_init(). Update copyright.
4131 * ABOUT-NLS: Removed.
4132 * gettext.c: Removed.
4133 * gettext.h: Get a simplified copy from the gettext package.
4135 * i18n/*.po: Moved to po/.
4138 * config/*: Created. Contains package configuration helper files.
4139 * config.guess, config.sub: Moved to config directory.
4141 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4142 Rework to use new-style autoconf features. Use the "external"
4143 mode for gettext. Make the build.sh config file conditional on
4144 whether build.sh.in exists, to avoid autoconf errors.
4145 * acinclude.m4: Removed almost all macros as being obsolete.
4146 Rewrote remaining macros to use AC_DEFINE.
4147 * acconfig.h: Removed.
4149 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4150 conditional to handle customs support. Remove special handling
4153 2002-04-20 Paul D. Smith <psmith@gnu.org>
4155 * function.c (func_call): Don't mark the argument variables $1,
4156 etc. as recursive. They've already been fully expanded so
4157 there's no need to do it again, and doing so strips escaped $'s.
4158 Reported by Sebastian Glita <glseba@yahoo.com>.
4160 * remake.c (notice_finished_file): Walk through double-colon
4161 entries via the prev field, not the next field!
4162 Reported by Greg McGary <greg@mcgary.org>.
4164 * main.c (main): If the user specifies -q and asks for a specific
4165 target which is a makefile, we got an assert. In that case it
4166 turns out we should continue normally instead.
4168 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4170 * i18n/he.po: Installed a new translation.
4172 2002-01-07 Paul D. Smith <psmith@gnu.org>
4174 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4176 2001-12-04 Paul D. Smith <psmith@gnu.org>
4178 * i18n/ja.po: Installed an updated translation.
4180 2001-09-06 Paul Eggert <eggert@twinsun.com>
4182 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4183 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4185 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4187 (main): Get rid of any avoidable limit on stack size.
4189 2001-09-04 Paul D. Smith <psmith@gnu.org>
4191 * i18n/da.po: Installed an updated translation.
4193 2001-08-03 Paul D. Smith <psmith@gnu.org>
4195 * i18n/fr.po: Installed an updated translation.
4196 Resolves Debian bug #106720.
4198 2001-06-13 Paul D. Smith <psmith@gnu.org>
4200 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4203 2001-06-11 Paul D. Smith <psmith@gnu.org>
4205 * i18n/ko.po: Installed a new translation.
4207 2001-05-06 Paul D. Smith <psmith@gnu.org>
4209 Modify the EINTR handling.
4211 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4212 the way in which we manage the file descriptor/signal handler race
4213 trap to be more efficient.
4215 2001-05-06 Paul Eggert <eggert@twinsun.com>
4217 Restart almost all system calls that are interrupted, instead
4218 of worrying about EINTR. The lone exception is the read() for
4221 * configure.in (HAVE_SA_RESTART): New macro.
4222 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4223 * main.c (main): Use SA_RESTART instead of the old,
4224 nonstandard SA_INTERRUPT.
4226 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4227 * main.c (bsd_signal): New function or macro,
4228 if the implementation doesn't supply it.
4229 (The bsd_signal function will be in POSIX 1003.1-200x.)
4230 (HANDLESIG): Remove.
4231 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4233 * make.h (EINTR_SET): Remove.
4234 (SA_RESTART): New macro.
4236 * arscan.c (ar_member_touch): Don't worry about EINTR.
4237 * function.c (func_shell): Likewise.
4238 * job.c (reap_children, free_child, new_job): Likewise.
4239 * main.c (main): Likewise.
4240 * remake.c (touch_file, name_mtime): Likewise.
4242 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4243 if fstat failed with errno!=EINTR, the error was ignored.
4245 * job.c (set_child_handler_action_flags): New function.
4246 (new_job): Use it to temporarily clear the SIGCHLD action flags
4247 while reading the token.
4249 2001-05-02 Paul D. Smith <psmith@gnu.org>
4251 * job.c (start_job_command): Don't add define/endef per-line flags
4252 to the top-level flags setting.
4254 2001-04-03 Paul D. Smith <psmith@gnu.org>
4256 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4257 bit on error, so check for odd return values, not non-0 return
4259 (VMS_get_member_info): Calculate the timezone differences correctly.
4260 Reported by John Fowler <jfowler@nyx.net>.
4263 2001-03-14 Paul D. Smith <psmith@gnu.org>
4265 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4266 value before invoking define_variable().
4267 Reported by John Fowler <jfowler@nyx.net>.
4269 2001-02-07 Paul D. Smith <psmith@gnu.org>
4271 * read.c (record_target_var): If we reset the variable due to a
4272 command-line variable setting overriding it, turn off the "append"
4275 2001-01-17 Paul D. Smith <psmith@gnu.org>
4277 * variable.c (lookup_variable) [VMS]: When getting values from the
4278 environment, allocate enough space for the _value_ plus escapes,
4279 not enough space for the name plus escapes :-/.
4280 Reported by John Fowler <jfowler@nyx.net>.
4282 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4283 warnings that make generates, so it doesn't look like an error.
4284 Reported by Karl Berry <karl@gnu.org>.
4287 Fix for PR/2020: Rework appended target-specific variables. I'm
4288 fairly confident this algorithm is finally correct.
4290 * expand.c (allocated_variable_append): Rewrite. Instead of
4291 expanding each appended variable then adding all the expanded
4292 strings together, we append all the unexpanded values going up
4293 through the variable set contexts, then expand the final result.
4294 This behaves just like non-target-specific appended variable
4295 values, while the old way didn't in various corner cases.
4296 (variable_append): New function: recursively append the unexpanded
4297 value of a variable, walking from the outermost variable scope to
4299 * variable.c (lookup_variable): Remove the code that looked up the
4300 variable set list if the found variable was "append". We don't
4302 (lookup_variable_in_set): Make this non-static so we can use it
4304 (try_variable_definition): Use lookup_variable_in_set() rather
4305 than faking out current_variable_set_list by hand (cleanup).
4306 * variable.h: Add a prototype for the now non-static
4307 lookup_variable_in_set().
4309 2000-11-17 Paul D. Smith <psmith@gnu.org>
4311 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4312 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4313 before throwing a fit.
4315 2000-11-17 Paul D. Smith <psmith@gnu.org>
4317 * read.c (readline): CRLF calculations had a hole, if you hit the
4318 buffer grow scenario just right. Reworked the algorithm to avoid
4319 the need for len or lastlen at all. Problem description with
4320 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4322 2000-10-24 Paul D. Smith <psmith@gnu.org>
4324 * gettext.c (SWAP): Declare this with the prototype, otherwise
4325 some systems don't work (non-32-bit? Reported for Cray T3E).
4326 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4328 2000-10-05 Paul D. Smith <psmith@gnu.org>
4330 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4331 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4333 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4335 2000-09-22 Paul D. Smith <psmith@gnu.org>
4337 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4338 parts of the real gettext.h here, and we expect to really include
4339 the real gettext.h later. If we keep this #define, it's ignored.
4341 2000-09-21 Paul D. Smith <psmith@gnu.org>
4343 * main.c (log_working_directory): Rework the text to use complete
4344 sentences, to make life simpler for the translators.
4346 2000-08-29 Paul D. Smith <psmith@gnu.org>
4348 * file.c (remove_intermediates): Print a debug message before we
4349 remove intermediate files, so the user (if she uses -d) knows
4352 2000-08-21 Paul D. Smith <psmith@gnu.org>
4354 * variable.c (try_variable_definition): Change how we handle
4355 target-specific append variable defns: instead of just setting the
4356 value, expand it as an append _but_ only within the current
4357 target's context. Otherwise we lose all but the last value if the
4358 variable is appended more than once within the current target
4359 context. Fixes PR/1831.
4361 2000-08-16 Paul D. Smith <psmith@gnu.org>
4363 * function.c (func_shell): Nul-terminate the buffer before
4364 printing an exec error message (just in case it's not!).
4365 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4367 2000-07-25 Paul D. Smith <psmith@gnu.org>
4369 * job.c (construct_command_argv_internal): Add "~" to the list of
4370 sh_chars[] which disallow optimizing out the shell call.
4372 2000-07-23 Paul Eggert <eggert@twinsun.com>
4374 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4375 supersedes --disable-nsec-timestamps.
4376 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4377 * README: Remove --disable-nsec-timestamps.
4379 * filedef.h (struct file.low_resolution_time): New member.
4380 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4381 * remake.c (update_file_1):
4382 Avoid spurious rebuilds due to low resolution time stamps,
4383 generalizing the earlier code that applied only to archive members.
4384 (f_mtime): Archive members always have low resolution time stamps.
4386 * configure.in: Remove --disable-nsec-timestamps, as this has
4387 been superseded by .LOW_RESOLUTION_TIME.
4389 2000-07-23 Paul Eggert <eggert@twinsun.com>
4391 * configure.in (enable_nsec_timestamps): Renamed from
4392 make_cv_nsec_timestamps, since enable/disable options
4393 shouldn't be cached.
4395 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4396 and Paul Eggert <eggert@twinsun.com>
4398 * file.c (file_timestamp_now):
4399 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4400 so that clock_gettime is not linked unless needed.
4402 * filedef.h (FILE_TIMESTAMP_HI_RES):
4403 Remove definition; "configure" now does this.
4405 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4406 to before high resolution file timestamp check,
4407 since that check now uses uintmax_t.
4408 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4409 high resolution file timestamps.
4410 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4411 so that we don't link in clock_gettime unnecessarily.
4413 2000-07-17 Paul D. Smith <psmith@gnu.org>
4415 * i18n/ja.po: New version of the translation file.
4417 2000-07-07 Paul D. Smith <psmith@gnu.org>
4419 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4420 the offset calculation.
4421 (name_mtime): Replace EINTR test with EINTR_SET macro.
4423 2000-07-07 Paul Eggert <eggert@twinsun.com>
4427 * remake.c (update_file_1):
4428 Avoid spurious rebuilds of archive members due to their
4429 timestamp resolution being only one second.
4430 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4431 the clock's resolution being lower than file timestamps'.
4432 When warning about future timestamps, report only the discrepancy,
4433 not the absolute value of the timestamp and the current time.
4435 * file.c (file_timestamp_now): New arg RESOLUTION.
4436 * filedef.h (file_timestamp_now): Likewise.
4437 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4439 2000-07-05 Paul D. Smith <psmith@gnu.org>
4441 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4442 to listp. Fixes PR/1793.
4444 2000-06-26 Paul Eggert <eggert@twinsun.com>
4446 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4448 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4450 * remake.c (f_mtime): Remove unused var memtime.
4452 2000-06-25 Martin Buchholz <martin@xemacs.org>
4454 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4455 Ran spell-check on make.texinfo.
4457 2000-06-23 Paul D. Smith <psmith@gnu.org>
4459 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4460 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4461 * make.h: Define these macros.
4463 * Version 3.79.1 released.
4465 * configure.in: Add a new option, --disable-nsec-timestamps, to
4466 avoid using sub-second timestamps on systems that support it. It
4467 can lead to problems, e.g. if your makefile relies on "cp -p".
4468 * README.template: Document the issue with "cp -p".
4470 * config.guess, config.sub: Updated.
