662 2010-07-01 Paul Smith <psmith@gnu.org>
664 * main.c (main): Append optional features using separate calls.

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

726 lowest directory index.
728 * implicit.c (pattern_search): Pass NULL for the index arguments in
729 the VPATH_SEARCH call.
731 * doc/make.texi (Directory Search for Link Libraries): Describe the

883 double-colons have a different meaning. Savannah bug #27497.
885 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
887 * configh.dos.template: Remove unconditional definition of
888 SYS_SIGLIST_DECLARED.
889 Include <sys/version.h> because ports of GCC 4.3.0 and later no
890 longer include it, so macros like __DJGPP_MINOR__ are no longer
891 defined automatically.
893 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
894 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
895 instead of using the hardcoded ones.
896 (SUBDIRS): doc subdir added.
897 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
898 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
899 create html formated docs. texi2html may not be ported to DOS.
900 (make.info, make.dvi, make.ps, make.html): Make targets depend on
902 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change

910 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
911 (tags-recursive): Allow for more than one subdir in the build
913 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
914 targets. Enter into doc/ to produce the targets.

917 2009-09-26 Paul Smith <psmith@gnu.org>
919 * read.c (record_files): Use free_ns() to free struct nameseq.
922 * rule.c (freerule): Use free_dep_chain().
924 * read.c (record_files): Free FILENAMES chain for implicit rules.
925 (eval): Static pattern targets go into the string cache.
927 * function.c (string_glob): Free NAME in the nameseq chain.
929 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
931 * implicit.c (pattern_search): Terminate early if we haven't
932 found any rules to try (performance improvement).
934 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
936 * implicit.c (pattern_search): Merge three parallel arrays,
937 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
938 of struct TRYRULE. In the old version the latter two arrays
939 had insufficient length.
941 2009-09-24 Paul Smith <psmith@gnu.org>
943 * implicit.c (pattern_search): Add back support for order-only
944 prerequisites for secondary expansion implicit rules, that were
945 accidentally dropped. If we find a "|", enable order-only mode
946 and set IGNORE_MTIME on all deps that are seen afterward.
947 (pattern_search): Fix memory leaks: for intermediate files where
948 we've already set the file variable and pattern variable sets, be
949 sure to either save or free them as appropriate.
951 2009-09-23 Paul Smith <psmith@gnu.org>
953 Rework the way secondary expansion is stored, for efficiency.
954 This changes secondary expansion so that ONLY WHEN we know we have
955 a possibility of needing secondary expansion, do we defer the
956 secondary expansion. This means more parsing the deps but we use
957 a lot less memory (due to the strcache). Also, this fixes
960 * read.c (eval): Don't parse the dep string here anymore.
961 (record_files): Take the dep argument as an unparsed string. If
962 secondary expansion is enabled AND the prereq string has a '$' in
963 it, then set NEED_2ND_EXPANSION and keep the entire string.
964 Otherwise, parse the dep string here to construct the dep list
965 with the names in the strcache.
967 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
968 duplicate the name string (others are in the strcache).
970 * implicit.c: Remove struct idep and free_idep_chain(): unused.
971 (struct patdeps): New structure to store prereq information.
972 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
973 which prerequisites need expansion, and expand only those.
975 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
976 and enter_prereqs(). split_prereqs() takes a fully-expanded string
977 and splits it into a DEP list, handling order-only prereqs.
978 (enter_prereqs): This function enters a list of DEPs into the file
979 database. If there's a stem defined, expand any pattern chars.
980 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
981 set. Use the above functions.
982 (snap_deps): Only perform second expansion on prereqs that need it,
983 as defined by the NEED_2ND_EXPANSION flag.
984 (print_prereqs): New function to print the prereqs
985 (print_file): Call print_prereqs() rather than print inline.
987 * hash.h (STRING_COMPARE): Take advantage of strcache() by
989 (STRING_N_COMPARE): Ditto.
990 (ISTRING_COMPARE): Ditto.
992 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
993 (parse_file_seq): Return void*
994 * read.c (parse_file_seq): Return void*.
995 (eval): Invoke macroized version of parse_file_seq()
996 * default.c (set_default_suffixes): Ditto.
997 * file.c (split_prereqs): Ditto.
998 * function.c (string_glob): Ditto.
999 * main.c (main): Ditto.
1000 * rule.c (install_pattern_rule): Ditto.
1002 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
1004 2009-09-16 Paul Smith <psmith@gnu.org>
1006 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
1008 * dep.h: Create alloc_dep() / free_dep() macros.
1010 * implicit.c (pattern_search): Take advantage of the new
1011 parse_file_seq() to add the directory prefix to each prereq.
1013 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
1014 all. Avoid reversing chains. Support adding prefixes.
1015 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
1016 cached/non-cached results.
1017 (eval): Remove multi_glob() & invoke new parse_file_seq().
1018 * rule.c (install_pattern_rule): Ditto.
1019 * main.c (main): Ditto.
1020 * implicit.c (pattern_search): Ditto.
1021 * function.c (string_glob): Ditto.
1022 * file.c (parse_prereqs): Ditto.
1023 * default.c (set_default_suffixes): Ditto.
1025 * variable.c (parse_variable_definition): Don't run off the end of
1026 the string if it ends in whitespace (found with valgrind).
1028 * commands.c (set_file_variables): Keep space for all targets in
1029 $? if -B is given (found with valgrind).
1031 2009-09-15 Paul Smith <psmith@gnu.org>
1033 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
1034 (xcalloc): Add new function.
1035 * make.h: New declarations.
1037 * ar.c (ar_glob_match): New calling method for concat().
1038 * main.c (main): Ditto.
1039 (decode_env_switches): Ditto.
1040 * read.c (eval_makefile): Ditto.
1041 (tilde_expand): Ditto.
1042 (parse_file_seq): Ditto.
1043 * variable.c (target_environment): Ditto.
1044 (sync_Path_environment): Ditto.
1046 * ar.c (ar_glob_match): Use xcalloc().
1047 * dir.c (file_impossible): Ditto.
1048 * file.c (enter_file): Ditto.
1049 * job.c (new_job): Ditto.
1050 * read.c (parse_file_seq): Ditto.
1051 * vmsfunctions.c (opendir): Ditto.
1053 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
1055 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
1056 inside the loop that looks up environment for PATH.

1061 sync_Path_environment.
1063 2009-08-02 Paul Smith <psmith@gnu.org>
1065 * remake.c (notice_finished_file): Ensure file->cmds is not null
1066 before looping through them. Fixes Savannah bug #21824.
1068 * doc/make.texi (Wildcard Examples): Clarify when objects is
1069 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1070 (Include): Clarify the behavior of -include.
1071 Fixes Savannah bug #18963.
1073 2009-08-01 Paul Smith <psmith@gnu.org>
1075 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1076 etc. come on the command line. Fixes Savannah bug #27093.
1078 * expand.c (expand_argument): If the argument is large enough use
1079 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1081 * variable.c (do_variable_definition): Avoid using alloca() to
1082 hold values, which can be large. Fixes Savannah bug #23960.
1084 * job.c (new_job): Use memmove() instead of strcpy() since both
1085 pointers are in the same memory block. Fixes Savannah bug #27148.
1086 Patch by Petr Machata.
1088 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1090 * job.c (construct_command_argv_internal): Add "ulimit" and
1091 "unset" to the sh_cmds for Unixy shells.
1093 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1095 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1096 that set make_cv_sys_gnu_glob, so they are also correctly set
1097 when the cache has been populated before.
1099 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1101 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1102 exist, as realpath(3) does where it's supported.
1104 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1106 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1107 (abspath): Support systems that define HAVE_DOS_PATHS (have
1108 drive letters in their file names). Use IS_PATHSEP instead of a
1109 literal '/' comparison. Fixes Savannah bug #26886.
1111 2009-06-14 Paul Smith <psmith@gnu.org>
1113 * remake.c (update_file_1): Remember the original file we marked
1114 as updating, so we can clear that flag again. If we find a target
1115 via vpath, FILE might change.
1116 (check_dep): Ditto. Fixes Savannah bug #13529.
1117 Patch by Reid Madsen <reid.madsen@tek.com>.
1119 2009-06-13 Paul Smith <psmith@gnu.org>
1121 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1122 included by MAKEFILES cannot give default goals.
1123 * read.c (eval): If set_default is not set, pass the no-default-goal
1124 value when we read included makefiles. Fixes Savannah bug #13401.
1126 * ar.c (ar_name): Ensure that targets with empty parens aren't
1127 considered archive member references: archive members must have a
1128 non-empty "member" string. Fixes Savannah bug #18435.
1130 * function.c (string_glob): Rely on multi_glob() to determine
1131 whether files exist or not. Remove call to file_exists_p() which
1132 is not always correct. Fixes Savannah bug #21231.
1133 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1134 then only files that really exist will be returned.
1135 * dep.h: Add new argument to multi_glob().
1136 * rule.c (install_pattern_rule): Ditto.
1137 * read.c (eval): Ditto.
1138 * main.c (main): Ditto.
1139 * implicit.c (pattern_search): Ditto.
1140 * file.c (parse_prereqs): Ditto.
1141 * default.c (set_default_suffixes): Ditto.
1143 2009-06-09 Paul Smith <psmith@gnu.org>
1145 * commands.c (set_file_variables): If always_make_flag is set,
1146 always add the prereq to $?. Fixes Savannah bug #17825.
1148 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1149 to rebuild the deps of all the also_make targets for that file.
1150 Fixes Savannah bug #19108.
1152 * implicit.c (pattern_search): Undo test for is_target, added by
1153 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1154 Rule Search Algorithm". Fixes Savannah bug #17752.
1156 * main.c (clean_jobserver): Clear the jobserver_fds options and
1157 set job_slots to the default when we clean up.
1158 (define_makeflags): Return the new MAKEFLAGS value.
1159 (main): Reset MAKEFLAGS in the environment when we re-exec.
1160 Fixes Savannah bug #18124.
1162 2009-06-08 Paul Smith <psmith@gnu.org>
1164 * read.c (eval): Collapse continuations post-semicolon on target-
1165 specific variables. Fixes Savannah bug #17521.
1167 2009-06-07 Paul Smith <psmith@gnu.org>
1169 * job.c (reap_children): For older systems without waitpid() (are
1170 there any of these left?) run wait(2) inside EINTRLOOP to handle
1171 EINTR errors. Fixes Savannah bug #16401.
1173 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1175 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1177 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1178 not the end, to catch second expansion $(eval ...) defining new
1179 target/prereq relationships during snap_deps.
1180 Fixes Savannah bug #24622.
1182 * read.c (record_files): The second-expansion "f->updating" hack
1183 was not completely correct: if assumed that the target with
1184 commands always had prerequisites; if one didn't then the ordering
1185 was messed up. Fixed for now to use f->updating to decide whether
1186 to preserve the last element in the deps list... but this whole
1187 area of constructing and reversing the deps list is too confusing
1188 and needs to be reworked. Fixes Savannah bug #21198.
1190 2009-06-06 Paul Smith <psmith@gnu.org>
1192 * hash.c (hash_insert): Remove useless test for NULL.
1193 Fixes Savannah bug #21823.
1195 * make.h: Move SET_STACK_SIZE determination to make.h.
1196 * main.c (main): New global variable, STACK_LIMIT, holds the
1197 original stack limit when make was started.
1198 * job.c (start_job_command): Reset the stack limit, if we changed it.
1199 Fixes Savannah bug #22010.
1201 * remake.c (check_dep): Only set the target's state to not-started
1202 if it's not already running. Found this while testing -j10 builds
1203 of glibc: various targets were being rebuilt multiple times.
1204 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1207 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1208 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1211 2009-06-04 Paul Smith <psmith@gnu.org>
1213 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1215 * maintMakefile: Modify access of config and gnulib Savannah
1216 modules to use GIT instead of CVS.
1218 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1219 Fixes Savannah bug #24655.
1221 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1222 this can happen during some invocations of $(eval ...) for example.
1223 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1225 2009-06-02 Paul Smith <psmith@gnu.org>
1227 * configure.in: Check for fileno()
1228 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1229 for the makefile file so invocations of $(shell ...) don't inherit it.
1230 Fixes Savannah bug #24277.
1232 2009-06-01 Paul Smith <psmith@gnu.org>
1234 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1235 expansion was handled incorrectly. Rework the default goal
1236 handling to save the variable only. Remove default_goal_file and
1238 * read.c (eval): Check default_goal_var, not default_goal_name.
1239 * read.c (record_target_var): Don't check default_goal_file here.
1241 2009-05-31 Paul Smith <psmith@gnu.org>
1243 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1244 it, and if the multi_glob() returns nothing (say it expanded to
1245 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1247 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1248 $(and ..) to the reference. Fixes Savannah bug #25694.
1250 * make.1: Be clear that some recipes will be executed even with -n.
1251 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1253 * doc/make.texi (Override Directive): Make more clear how
1254 overrides and appends interact.
1255 Elucidates part of Savannah bug #26207.
1257 * read.c (record_target_var): Don't reset the origin on
1258 target-specific variables; try_variable_definition() will handle
1259 this correctly. Fixes Savannah bug #26207.
1261 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1262 Fixes Savannah bug #25712.
1264 * implicit.c (pattern_search): Keep a pointer to the beginning of
1265 the filename and save that instead of the constructed pointer.
1266 Fixes Savannah bug #26593.
1267 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1269 2009-05-30 Paul Smith <psmith@gnu.org>
1271 * doc/make.texi (Multi-Line): Add a description of the new abilities
1272 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1273 "command sequence" vs. "recipe" syntax.
1274 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1275 after a define, to create variables with those flavors.
1277 2009-05-25 Paul Smith <psmith@gnu.org>
1279 Reworked the parser for variable assignments to allow multiple
1280 modifiers, and in any order. Also allows variable and
1281 prerequisites to be modifier names ('export', 'private', etc.)
1283 * NEWS: Add notes about user-visible changes.
1285 * read.c (struct vmodifiers): Remember what modifiers were seen.
1286 (parse_var_assignment): New function to parse variable assignments.
1287 (eval): Call the new function. Handle variable assignments earlier.
1289 * variable.c (parse_variable_definition): Only parse; don't create var.
1290 (assign_variable_definition): Call parse, then create the var.
1292 2009-05-24 Paul Smith <psmith@gnu.org>
1294 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1295 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1297 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1299 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1300 Fixes Savannah bug #25412.
1302 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1303 prototype for xmalloc.
1304 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1305 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1306 Loop over an array of extensions, instead of duplicating the same
1307 code inline. Use SearchPath followed by CreateFile, instead of
1308 the obsolete OpenFile. Fixes Savannah bug #17277.
1309 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1310 to `find_file'. Fixes Savannah bug #25662.
1312 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1314 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1315 Fixes Savannah bug #20495.
1317 2009-02-28 Ralf Wildenhues <address@hidden>
1319 * doc/make.texi (Instead of Execution): Document interaction of
1320 -t with phony targets.
1322 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1324 Introduce a new keyword "private" which applies to target-specific
1325 variables and prevents their values from being inherited.
1327 * variable.h (struct variable): Add private_var flag to each variable.
1328 Add a flag to specify which list entry switches to the parent target.
1329 * variable.c (define_variable_in_set): Initialize private_var flag.

1342 * make.h: Rename savestring to xstrndup.
1343 * commands.c (chop_commands): Ditto.
1344 * function.c (func_foreach): Ditto.
1345 * read.c (eval, record_files): Ditto.
1346 * variable.c (define_variable_in_set): Ditto.
1348 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1350 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1353 * w32/subproc/build.bat (GCCBuild): Likewise.
1355 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1357 * job.c (construct_command_argv_internal): Avoid extra backslash
1358 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1361 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1363 * README.W32.template: Remove obsolete text about non-support for
1364 -jN without Unixy shell. Remove obsolete text about not supplying
1365 Visual Studio project files (we do supply them). Modify text to
1366 prefer GCC builds to MSC builds.
1368 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1370 * doc/make.texi (Empty Targets): Fix typo.

1385 `value' field is NULL.
1387 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1389 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1391 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1392 (TEXINFOS): Value changed to `doc/make.texi'.
1393 (.SUFFIXES): Use .texi instead of .texinfo.
1394 (make.info, make.dvi): Depend on doc/make.texi.
1395 (.texi.info): New target, instead of ".texinfo.info". Change -I
1396 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1397 (.texi): New target, instead of ".texinfo". Change -I switch to
1398 $(MAKEINFO) to look in doc/. Use --no-split.
1399 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1400 switch to $(MAKEINFO) to look in doc/.
1401 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1402 "*.i[0-9][0-9]" (due to --no-split above).

1404 (html, make_1.html): New targets.
1405 (.PHONY): Add "html".

1411 HAVE_DECL_SYS_SIGLIST.
1413 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1414 build does not use child_execute_job.
1416 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1417 export the SHELL environment variable to the child.
1419 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1421 * config.h.W32: Include sys/types.h.

1438 * remake.c (f_mtime): Print time difference values between 100 and
1439 ULONG_MAX in fixed-point notation rather than in exponention notation.
1441 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1443 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1444 a more complex value than a simple shell: if it's not a default
1445 shell now then expand it and see if is a default shell then.
1447 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1449 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1450 pathnames, with const strings.
1451 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1452 from the template (used for building from CVS, not a dist).
1454 2007-10-10 Paul Smith <psmith@gnu.org>
1456 * make.h: Add a prototype for w32_kill() (change suggested by
1457 Yongwei Wu <wuyongwei@gmail.com>).
1459 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1461 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1462 directories in Path.
1464 2007-09-12 Paul Smith <psmith@gnu.org>

1467 Provided by Diego Biurrun <diego@biurrun.de>
1468 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1469 Provided by Diego Biurrun <diego@biurrun.de>
1471 2007-09-11 Paul Smith <psmith@gnu.org>
1473 * doc/make.texi (Special Variables): Moved this into the "How to
1474 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1475 (MAKEFILE_LIST) No longer a section; this was added into the
1476 "Special Variables" section.
1477 (Rule Introduction): Reference .RECIPEPREFIX.
1478 (Simple Makefile): Ditto.
1479 (Rule Syntax): Ditto.
1480 (Command Syntax): Ditto.
1481 (Error Messages): Ditto.
1483 2007-09-10 Paul Smith <psmith@gnu.org>
1485 * commands.c (print_commands): Don't print an extra line in the
1486 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1488 * read.c (construct_include_path): Add the full string to the cache; we
1489 were chopping the last char.
1491 * NEWS: Announce the .RECIPEPREFIX special variable.
1492 * variable.c (lookup_special_var): Rename from handle_special_var().
1493 (lookup_variable): Call the new name.

1495 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1496 (do_variable_definition): Call it.
1497 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1498 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1499 * main.c (main): Create the .RECIPEPREFIX special variable.
1500 * read.c (eval): Remove the cmd_prefix characters from the command
1501 scripts here, so they're not stored in the commands array at all,
1502 rather than waiting and stripping them out during command construction.
1503 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1505 2007-08-15 Paul Smith <psmith@gnu.org>
1507 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1508 file has had the section info removed, so add some to make.texi
1509 before we include it.
1511 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1513 * remake.c (check_dep): Reset the target state for intermediate
1514 files. They might have been considered before but not updated
1515 then (order-only for example) but they will be this time.
1516 Fixes Savannah bug #'s 3330 and 15919.
1518 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1520 Fix Savannah bug #20549:
1521 * function.c (func_shell): Call construct_command_argv with zero
1523 * job.c (construct_command_argv_internal): New argument FLAGS; all
1525 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1527 * job.h (construct_command_argv_internal): Update prototype.
1529 2007-07-13 Paul Smith <psmith@gnu.org>
1531 * file.c (expand_deps): Use variable_buffer as the start of the
1532 buffer, not the original pointer (in case it was reallocated).
1533 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1534 Fixes Savannah bug #20452.
1536 2007-07-04 Paul Smith <psmith@gnu.org>

1559 * job.c (new_job): Add debug info to specify where make found the
1560 command script it is running to build a target.
1561 Fixes Savannah bug #18617.
1563 * default.c (default_suffixes,default_suffix_rules,default_variables):
1564 Add support for Objective C. Fixes Savannah bug #16389.
1565 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1567 * function.c (func_lastword): Initialize p.
1569 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1570 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from

1575 Fix Savannah bug #19656:
1577 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1579 * make.h: Change all case-insensitive string compares to use
1580 strcasecmp() (from POSIX). If we don't have that but do have one
1581 of the others, define strcasecmp to be one of those instead. If
1582 we don't have any, declare a prototype for our own version.
1584 * misc.c (strcasecmp): Use this if we can't find any native
1585 case-insensitive string comparison function.
1586 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1587 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1589 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1590 strcasecmp() instead of stricmp().
1591 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1592 instead of strcmpi().
1593 * acinclude.m4: Remove the strcasecmp() check from here.
1595 2007-03-21 Paul Smith <psmith@gnu.org>
1597 * configure.in: Don't turn on case-insensitive file system support
1598 if --disable-... is given. Fixes Savannah bug #19348.
1600 2007-03-19 Paul Smith <psmith@gnu.org>
1602 * ALL: Use the strcache for all file name strings, or other
1603 strings which we will never free. The goal is to save memory by
1604 avoiding duplicate copies of strings. However, at the moment this
1605 doesn't save much memory in most situations: due to secondary
1606 expansion we actually save prerequisite lists twice (once before
1607 the secondary expansion, and then again after it's been parsed
1608 into individual file names in the dep list). We will resolve this
1609 in a future change, by doing the parsing up-front for targets
1610 where secondary expansion is not set.
1612 Moving things into the strcache also allows us to use const
1613 pointers in many more places.
1615 2007-01-03 Paul Smith <psmith@gnu.org>
1617 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1618 the function, not just the first. Fixes Savannah bug #18680.
1620 2006-11-18 Paul Smith <psmith@gnu.org>
1622 * strcache.c (strcache_add_len): Don't allocate a new buffer
1623 unless the string is not already nil-terminated. Technically this
1624 is a violation of the standard, since we may be passed an array
1625 that is not long enough to test one past. However, in make this
1626 is never true since we only use nil-terminated strings or
1627 sub-strings thereof.
1629 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1631 * main.c: New global cmd_prefix, defaults to '\t'.
1632 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1635 * dir.c: Constified.
1636 (dir_contents_file_exists_p): Check for an error return from
1637 readdir(), just in case.
1639 * commands.c: Constified.
1640 * default.c: Constified.
1641 * expand.c: Constified.
1642 * function.c: Partial constification.
1643 * variable.c: Partial constification.
1644 * vmsify.c: Constification. Hard to test this but I hope I didn't
1646 * vpath.c: Partial constification.
1647 * w32/pathstuff.c: Partial constification.
1649 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1651 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1652 backslashes and drive letters as absolute.
1654 2006-10-22 Paul Smith <psmith@gnu.org>

1658 2006-10-21 Paul Smith <psmith@gnu.org>
1661 * arscan.c: Constified.
1663 2006-09-30 Paul Smith <psmith@gnu.org>
1665 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1666 point to lastword since the example was updated.
1667 Fixes Savannah bug #16304.
1668 (Secondary Expansion): Correct example description.
1669 Fixes Savannah bug #16468.
1670 (Makefile Contents): Clarify that comments cannot appear within
1671 variable references or function calls.
1672 Fixes Savannah bug #16577.
1673 (Special Targets): Clarify how .NOTPARALLEL works in recursion.

1677 prerequisites. Fixes Savannah bug #17880.
1678 (Rule Syntax): "lise" -> "list"
1679 (Multiple Rules): ... -> @dots{}
1680 (Splitting Lines): ditto.
1682 * remake.c (update_file_1): Prereqs that don't exist should be
1683 considered changed, for the purposes of $?.
1684 Fixes Savannah bug #16051.
1686 * make.1: Remove extraneous "+".

1725 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1726 that don't have extended grep.
1727 (cvsclean): Use $(PERL) instead of perl.
1729 2006-04-09 Paul D. Smith <psmith@gnu.org>
1731 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1733 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1734 inner-scope variables don't mask outer-scope variables.
1736 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

1739 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1740 values from memory allocation functions: they return void* and so
1741 don't need to be cast. Also remove (char *) casts of arguments to

1775 Version 3.81 released.
1777 * NEWS: Updated for 3.81.
1779 * README.cvs: Mention that vpath builds are not supported out of
1780 CVS. Fixes Savannah bug #16236.

1795 Declare and define sh_chars_sh[].
1797 2006-03-23 Paul D. Smith <psmith@gnu.org>
1799 * configure.in: Look for build.sh.in in $srcdir so it will be
1800 built for remote configurations as well.
1802 * Makefile.am: Make sure to clean up build.sh during distclean.
1803 Fixes Savannah bug #16166.
1805 * misc.c (log_access): Takes a const char *.

1807 Both fixes for Savannah bug #16170.
1809 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1811 * implicit.c (pattern_search): Call set_file_variables only
1812 if we have prerequisites that need second expansion. Fixes
1813 Savannah bug #16140.
1815 2006-03-19 Paul D. Smith <psmith@gnu.org>
1817 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1818 memory on hosts that don't support it directly.

1821 make sure I don't forget any).
1823 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1825 (die): Cleanup code was removed from here; call the new function.
1826 (main): If we are re-execing, clean up the jobserver first so we
1827 don't leak file descriptors.

1830 2006-03-17 Paul D. Smith <psmith@gnu.org>
1832 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1833 allow multiple concurrent runs.
1834 Patch from Joseph Myers <joseph@codesourcery.com>
1836 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1838 * dep.h (struct dep): Add the stem field.
1839 * misc.c (alloc_dep, free_dep): New functions.
1840 (copy_dep_chain): Copy stem.
1841 (free_dep_chain): Use free_dep.
1842 * read.c (record_files): Store stem in the dependency line.
1843 * file.c (expand_deps): Use stem stored in the dependency line. Use
1844 free_dep_chain instead of free_ns_chain.
1845 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1846 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1847 * main.c (main, handle_non_switch_argument): Ditto.
1848 * remake.c (check_dep): Ditto.

1851 2006-03-14 Paul D. Smith <psmith@gnu.org>

1854 expanding the result, we expand (or not, if it's simple) each part
1856 (allocated_variable_append): Don't expand the final result.
1857 Fixes Savannah bug #15913.
1859 2006-03-09 Paul Smith <psmith@gnu.org>
1861 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1862 listed non-existent files as changed. Turns out there's a bug in
1863 the Linux kernel builds which means that this change causes
1864 everything to rebuild every time. We will re-introduce this fix
1865 in the next release, to give them time to fix their build system.
1866 Fixes Savannah bug #16002.
1867 Introduces Savannah bug #16051.
1869 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1881 * variable.c (merge_variable_set_lists): It's legal for *setlist0
1882 to be null; don't core in that case.
1884 2006-02-19 Paul D. Smith <psmith@gnu.org>
1886 * commands.c (set_file_variables): Realloc, not malloc, the static
1887 string values to avoid memory leaks.
1889 * expand.c (recursively_expand_for_file): Only set reading_file to
1890 an initialized value.
1892 * implicit.c (pattern_search): We need to make a copy of the stem
1893 if we get it from an intermediate dep, since those get freed.
1895 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1897 (enter_file) [VMS]: Ditto.
1898 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

1902 * job.c (construct_command_argv_internal): Fix last change.
1904 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1905 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1906 the calls to _beginthreadex.
1908 * expand.c (recursively_expand_for_file): Initialize `save' to
1909 prevent compiler warnings.
1911 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1913 * job.c (construct_command_argv_internal): Don't create a temporary
1914 script/batch file if we are under -n. Call _setmode to switch the
1915 script file stream to text mode.
1917 2006-02-17 Paul D. Smith <psmith@gnu.org>
1919 * variable.c (merge_variable_set_lists): Don't try to merge the
1920 global_setlist. Not only is this useless, but it can lead to
1921 circularities in the linked list, if global_setlist->next in one
1922 list gets set to point to another list which also ends in
1924 Fixes Savannah bug #15757.
1926 2006-02-15 Paul D. Smith <psmith@gnu.org>
1928 Fix for Savannah bug #106.
1930 * expand.c (expanding_var): Keep track of which variable we're
1931 expanding. If no variable is being expanded, it's the same as
1933 * make.h (expanding_var): Declare it.
1934 * expand.c (recursively_expand_for_file): Set expanding_var to the
1935 current variable we're expanding, unless there's no file info in
1936 it (could happen if it comes from the command line or a default
1937 variable). Restore it before we exit.
1938 * expand.c (variable_expand_string): Use the expanding_var file
1939 info instead of the reading_file info.

1945 (handle_function): Ditto.
1947 2006-02-14 Paul D. Smith <psmith@gnu.org>
1949 * read.c (eval): Even if the included filenames expands to the
1950 empty string we still need to free the allocated buffer.
1952 * implicit.c (pattern_search): If we allocated a variable set for
1953 an impossible file, free it.
1954 * variable.c (free_variable_set): New function.
1955 * variable.h: Declare it.
1957 * read.c (read_all_makefiles): Makefile names are kept in the
1958 strcache, so there's never any need to alloc/free them.
1961 * main.c (main): Add "archives" to the .FEATURES variable if
1962 archive support is enabled.
1963 * doc/make.texi (Special Variables): Document it.
1965 2006-02-13 Paul D. Smith <psmith@gnu.org>
1967 * implicit.c (pattern_search): Add checking for DOS pathnames to
1968 the pattern rule target LASTSLASH manipulation.

1973 * (ALL FILES): Updated copyright and license notices.
1975 2006-02-10 Paul D. Smith <psmith@gnu.org>
1977 A new internal capability: the string cache is a read-only cache
1978 of strings, with a hash table interface for fast lookup. Nothing
1979 in the cache will ever be freed, so there's no need for reference
1980 counting, etc. This is the beginning of a full solution for
1981 Savannah bug #15182, but for now we only store makefile names here.
1983 * strcache.c: New file. Implement a read-only string cache.
1984 * make.h: Add prototypes for new functions.
1985 * main.c (initialize_global_hash_tables): Initialize the string cache.
1986 (print_data_base): Print string cache stats.
1987 * read.c (eval_makefile): Use the string cache to store makefile
1988 names. Rewrite the string allocation to be sure we free everything.
1990 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1992 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1993 directory time stamp didn't change, except on FAT filesystems.
1994 Suggested by J. David Bryan <jdbryan@acm.org>.
1996 2006-02-09 Paul D. Smith <psmith@gnu.org>
1998 * function.c (func_or): Implement a short-circuiting OR function.
1999 (func_and): Implement a short-circuiting AND function.
2000 (function_table_init): Update the table with the new functions.
2001 * doc/make.texi (Conditional Functions): Changed the "if" section
2002 to one on general conditional functions. Added documentation for
2003 $(and ...) and $(or ...) functions.
2004 * NEWS: Note new $(and ...) and $(or ...) functions.

2013 2006-02-06 Paul D. Smith <psmith@gnu.org>
2015 * vpath.c (selective_vpath_search): If the file we find has a
2016 timestamp from -o or -W, use that instead of the real time.
2017 * remake.c (f_mtime): If the mtime is a special token from -o or
2018 -W, don't overwrite it with the real mtime.
2019 Fixes Savannah bug #15341.
2021 Updates from Markus Mauhart <qwe123@chello.at>:

2024 (process_signal, process_last_err, process_exit_code): Manage
2025 invalid handle values.
2026 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
2027 manage invalid handles; remove them.

2036 Fixes Savannah bug #15533.
2037 * filedef.h (struct file): Add a new LAST pointer.
2039 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
2040 the comparison. For 64-bits systems the result of the subtraction
2041 might not fit into an int. Use comparison instead.
2042 Fixes Savannah bug #15534.
2044 * doc/make.texi: Update the chapter on writing commands to reflect
2045 the changes made in 3.81 for backslash/newline and SHELL handling.
2047 2006-02-01 Paul D. Smith <psmith@gnu.org>
2049 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
2050 variable st is not used when it's not initialized.
2051 Patch from Eli Zaretskii <eliz@gnu.org>.
2053 2006-01-31 Paul D. Smith <psmith@gnu.org>

2060 J. Grant <jg@jguk.org>.
2062 * main.c: Update the copyright year in the version output.
2063 * prepare_w32.bat: Remove this file from the distribution.
2065 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2067 * remake.c (update_goal_chain): Set g->changed instead of
2068 incrementing it, as it is only 8-bit wide, and could overflow if
2069 many commands got started in update_file.

2083 are already more children than sub_proc.c can handle, behave as if
2084 the load were too high.

2088 2006-01-14 Eli Zaretskii <eliz@gnu.org>
2090 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
2091 the shell is not sh.exe.
2093 * job.c (create_batch_file): Renamed from create_batch_filename;
2094 all callers changed. Don't close the temporary file; return its
2095 file descriptor instead. New arg FD allows to return the file
2097 (construct_command_argv_internal): Use _fdopen instead of fopen to
2098 open the batch file.
2100 2006-01-04 Paul D. Smith <psmith@gnu.org>
2102 * readme.vms: Updates for case-insensitive VMS file systems from
2103 Hartmut Becker <Hartmut.Becker@hp.com>.
2104 * dir.c (vms_hash): Ditto.
2105 * vmsify.c (copyto): Ditto.
2106 * vmsfunctions.c (readdir): Ditto.
2108 * make.1: Add a section on the exit codes for make.
2110 * doc/make.texi: A number of minor updates to the documentation.
2112 2006-01-03 Paul D. Smith <psmith@gnu.org>
2114 * remake.c (update_file_1): Mark a prerequisite changed if it
2117 * read.c (eval): Be sure to strip off trailing whitespace from the
2118 prerequisites list properly. Also, initialize all fields in
2119 struct dep when creating a new one.
2121 2005-12-28 Paul D. Smith <psmith@gnu.org>
2123 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2124 disable warnings for MSC.
2125 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2127 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2129 * doc/make.texi (Execution): Add a footnote about changes in
2130 handling of backslash-newline sequences. Mention the differences
2131 on MS-DOS and MS-Windows.
2133 * NEWS: More details about building the MinGW port and a pointer
2134 to README.W32. Fix the section name that describes the new
2135 backward-incompatible processing of backslash-newline sequences.
2136 The special processing of SHELL set to "cmd" is only relevant to
2137 MS-Windows, not MS-DOS.
2139 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2141 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2142 to DWORD, to avoid compiler warnings.
2143 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2144 use %ld in format, to avoid compiler warnings.
2146 * doc/make.texi (Special Targets): Fix a typo.
2147 (Appending): Fix cross-reference to Setting.
2148 (Special Variables, Secondary Expansion, File Name Functions)
2149 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2150 periods after a sentence.
2151 (Execution): Add @: after "e.g.".
2152 (Environment): Fix punctuation.
2153 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2154 (Shell Function, Target-specific): Add @: after "vs."
2156 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2158 * read.c (record_target_var): Initialize variable's export field
2159 with v_default instead of leaving it "initialized" by whatever
2160 garbage happened to be on the heap.
2162 2005-12-12 Paul D. Smith <psmith@gnu.org>
2164 * make.1: Fix some display errors and document all existing options.
2165 Patch by Mike Frysinger <vapier@gentoo.org>.
2167 2005-12-11 Paul D. Smith <psmith@gnu.org>
2169 * implicit.c (pattern_search): If 2nd expansion is not set for
2170 this implicit rule, replace the pattern with the stem directly,
2171 and don't re-expand the variable list. Along with the other
2172 .SECONDEXPANSION changes below, fixes bug #13781.
2174 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2176 * implicit.c (pattern_search): Mark other files that this rule
2177 builds as targets so that they are not treated as intermediates
2178 by the pattern rule search algorithm. Fixes bug #13022.
2180 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2182 * remake.c (notice_finished_file): Propagate the change of
2183 modification time to all the double-colon entries only if
2184 it is the last one to be updated. Fixes bug #14334.
2186 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2188 * function.c (func_flavor): Implement the flavor function which
2189 returns the flavor of a variable.
2190 * doc/make.texi (Functions for Transforming Text): Document it.
2191 * NEWS: Add it to the list of new functions.
2193 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2195 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2197 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2198 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2200 2005-10-26 Paul Smith <psmith@gnu.org>
2202 * read.c (record_files): Don't set deps flags if there are no deps.
2203 * maintMakefile: We only need to build the templates when we are
2204 creating a distribution, so don't do it for "all".
2206 2005-10-24 Paul D. Smith <psmith@gnu.org>
2208 Make secondary expansion optional: its enabled by declaring the
2209 special target .SECONDEXPANSION.
2211 * NEWS: Update information on second expansion capabilities.
2212 * doc/make.texi (Secondary Expansion): Document the
2213 .SECONDEXPANSION special target and its behavior.
2214 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2215 prerequisite list was found in a static pattern rule.
2216 (free_dep_chain): Declare a prototype.
2217 * file.c (parse_prereqs): New function: break out some complexity
2219 (expand_deps): If we aren't doing second expansion, replace % with
2220 the stem for static pattern rules. Call the new function.
2221 * filedef.h (parse_prereqs): Declare a prototype.
2222 * implicit.c (pattern_search): Initialize the new staticpattern
2224 * main.c (second_expansion): Declare a global variable to remember
2225 if the special target has been seen. Initialize the new
2226 staticpattern field for prerequisites.
2227 * make.h: Extern for second_expansion.
2228 * misc.c (free_dep_chain): New function: frees a struct dep list.
2229 * read.c (read_all_makefiles): Initialize the staticpattern field.
2230 (eval_makefile): Ditto.
2231 (record_files): Check for the .SECONDEXPANSION target and set
2232 second_expansion global if it's found.
2233 Use the new free_dep_chain() instead of doing it by hand.
2234 Set the staticpattern field for prereqs of static pattern targets.
2236 2005-10-16 Paul D. Smith <psmith@gnu.org>
2238 * main.c (main): Set CURDIR to be a file variable instead of a
2239 default, so that values of CURDIR inherited from the environment
2240 won't override the make value.
2242 2005-09-26 Paul D. Smith <psmith@gnu.org>
2244 * job.c (construct_command_argv_internal): If the line is empty
2245 remember to free the temporary argv strings.
2248 2005-09-16 Paul D. Smith <psmith@gnu.org>
2250 * job.c (start_job_command): The noerror flag is a boolean (single
2251 bit); set it appropriately.
2252 Reported by Mark Eichin <eichin@metacarta.com>
2254 2005-08-29 Paul D. Smith <psmith@gnu.org>
2256 * function.c (func_error): On Windows, output from $(info ...)
2257 seems to come in the wrong order. Try to force it with fflush().
2259 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2261 * read.c (record_files): Move code that sets stem for static
2262 pattern rules out of the if (!two_colon) condition so it is
2263 also executed for two-colon rules. Fixes Savannah bug #13881.
2265 2005-08-08 Paul D. Smith <psmith@gnu.org>
2267 * make.h: Don't test that __STDC__ is non-0. Some compilers
2268 (Windows for example) set it to 0 to denote "ISO C + extensions".
2271 2005-08-07 Paul D. Smith <psmith@gnu.org>
2273 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2274 conditional (slightly different version of a fix from Eli).
2276 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2277 If make is running in parallel without -k and two jobs die in a
2278 row, but not too close to each other, then make will quit without
2279 waiting for the rest of the jobs to die.
2281 * main.c (die): Don't reset err before calling reap_children() the
2282 second time: we still want it to be in the error condition.
2283 * job.c (reap_children): Use a static variable, rather than err,
2284 to control whether or not the error message should be printed.
2286 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2288 * w32/subproc/sub_proc.c: Include signal.h.
2289 (process_pipe_io, process_file_io): Pass a pointer to a local
2290 DWORD variable to GetExitCodeProcess. If the exit code is
2291 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2293 * job.c [WINDOWS32]: Include windows.h.
2294 (main_thread) [WINDOWS32]: New global variable.
2295 (reap_children) [WINDOWS32]: Get the handle for the main thread
2296 and store it in main_thread.
2298 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2299 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2300 doing anything else. When we are done, close the main thread
2301 handle and exit with status 130.
2303 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2305 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2308 * main.c (find_and_set_default_shell): If found a DOSish shell,
2309 set sh_found and the value of default_shell, and report the
2310 findings in debug mode.
2312 * job.c (construct_command_argv_internal): Check unixy_shell, not
2313 no_default_sh_exe, to decide whether to use Unixy or DOSish
2316 * README.W32: Update with info about the MinGW build.
2318 * build_w32.bat: Support MinGW.
2320 * w32/subproc/build.bat: Likewise.
2322 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2323 printing DWORD args.
2325 * function.c (windows32_openpipe): Fix format strings for printing
2328 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2330 (start_job_command): Fix format string for printing the result of
2332 (start_job_command) [WINDOWS32]: Do not define.
2333 (exec_command): Fix format string for printing HANDLE args.
2335 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2336 to avoid compiler warnings.
2337 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2338 (Note: some of these fixes were submitted independently by J. Grant)
2340 2005-07-30 J. Grant <jg@jguk.org>
2342 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2343 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2344 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2346 2005-07-15 Paul Smith <psmith@gnu.org>
2348 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2349 we don't have a POSIX shell, then revert to the old
2350 backslash-newline behavior (where they are stripped).
2353 2005-07-08 Paul D. Smith <psmith@gnu.org>
2355 * config.h.W32.template: Reorder to match the standard config.h,
2356 for easier comparisons.
2357 From J. Grant <jg@jguk.org>
2359 * maintMakefile: Remove .dep_segment before overwriting it, in
2360 case it's not writable or noclobber is set.
2361 * expand.c (variable_expand_string): Cast result of pointer
2362 arithmetic to avoid a warning.
2363 * main.c (switches): Add full-fledged final initializer.
2365 2005-07-06 Paul D. Smith <psmith@gnu.org>
2367 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2368 * signame.c (strsignal): If we found _sys_siglist[] or
2369 __sys_siglist[] use those instead of sys_siglist[].
2370 From Albert Chin <china@thewrittenword.com>
2372 2005-07-04 Paul D. Smith <psmith@gnu.org>
2374 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2375 globfree(); set up to use the GNU versions.
2376 From Martin Zinser <zinser@zinser.no-ip.info>
2378 2005-07-03 Paul D. Smith <psmith@gnu.org>
2380 From J. Grant <jg@jguk.org>:
2382 * README.W32.template: Update the Windows and tested MSVC versions.
2383 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2384 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2385 * build_w32.bat: Ditto.
2386 * w32/subproc/build.bat: Ditto.
2388 2005-06-28 Paul D. Smith <psmith@gnu.org>
2390 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2391 declaration was checked but not present.
2393 2005-06-27 Paul D. Smith <psmith@gnu.org>
2395 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2396 to unsigned long. Fixes Savannah bug #13550.
2398 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2399 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2400 Fixes Savannah bug #13551.
2402 2005-06-26 Paul D. Smith <psmith@gnu.org>
2404 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2405 it if ANSI_STRING is not set.
2407 2005-06-25 Paul D. Smith <psmith@gnu.org>
2409 * read.c (eval): If no filenames are passed to any of the
2410 "include" variants, don't print an error.
2411 * doc/make.texi (Include): Document this.
2412 Fixes Savannah bug #1761.
2414 * job.c (construct_command_argv_internal): Sanitize handling of
2415 backslash/newline pairs according to POSIX: that is, keep the
2416 backslash-newline in the command script, but remove a following
2417 TAB character, if present. In the fast path, make sure that the
2418 behavior matches what the shell would do both inside and outside
2419 of quotes. In the slow path, quote the backslash and put a
2420 literal newline in the string.
2421 Fixes Savannah bug #1332.
2422 * doc/make.texi (Execution): Document the new behavior and give
2424 * NEWS: Make a note of the new behavior.
2426 * make.h [WINDOWS32]: #include <direct.h>.
2427 Fixes Savannah bug #13478.
2429 * remake.c (name_mtime): If the stat() of a file fails and the -L
2430 option was given and the file is a symlink, take the best mtime of
2431 the symlink we can get as the mtime of the file and don't fail.
2432 Fixes Savannah bug #13280.
2434 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2435 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2436 inside a variable reference. Make this function static as it's
2438 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2439 parsing an unexpanded line looking for semicolons.
2440 Fixes Savannah bug #1454.
2441 * misc.c (remove_comments): Move this to read.c and make it static
2442 as it's only used there. Call find_char_unquote() with new arg.
2443 * make.h: Remove prototypes for find_char_unquote() and
2444 remove_comments() since they're static now.
2446 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2447 its export flag and obtain its value. When we need to re-exec,
2448 increment the value and add it into the environment.
2449 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2450 * NEWS: Mention MAKE_RESTARTS.
2451 * main.c (always_make_set): New variable. Change the -B option to
2452 set this one instead.
2453 (main): When checking makefiles, only set always_make_flag if
2454 always_make_set is set AND the restarts flag is 0. When building
2455 normal targets, set it IFF always_make_set is set.
2456 (main): Avoid infinite recursion with -W, too: only set what-if
2457 files to NEW before we check makefiles if we've never restarted
2458 before. If we have restarted, set what-if files to NEW _after_ we
2460 Fixes Savannah bug #7566:
2462 2005-06-17 Paul D. Smith <psmith@gnu.org>
2464 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2465 in the prerequisites list.
2467 2005-06-12 Paul D. Smith <psmith@gnu.org>
2469 Fix Savannah bug # 1328.
2471 * configure.in: Check for atexit().
2472 * misc.c (close_stdout): Test stdout to see if writes to it have
2473 failed. If so, be sure to exit with a non-0 error code. Based on
2474 code found in gnulib.
2475 * make.h: Prototype.
2476 * main.c (main): Install close_stdout() with atexit().
2478 2005-06-10 Paul D. Smith <psmith@gnu.org>
2480 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2482 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2483 headers; make vmsWaitForChildren() static; extern vmsify().
2484 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2485 Don't create child_execute_job() here (it's in vmsjobs.c).
2486 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2488 2005-06-09 Paul D. Smith <psmith@gnu.org>
2490 * variable.c (push_new_variable_scope): File variables point
2491 directly to the global_setlist variable. So, inserting a new
2492 scope in front of that has no effect on those variables: they
2493 don't go through current_variable_set_list. If we're pushing a
2494 scope and the current scope is global, push it "the other way" so
2495 that the new setlist is in the global_setlist variable, and
2496 next points to a new setlist with the global variable set.
2497 (pop_variable_scope): Properly undo a push with the new
2499 Fixes Savannah bug #11913.
2501 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2503 * job.c (reap_children): Don't die of the command failed but
2504 the dontcare flag is set. Fixes Savannah bug #13216.
2506 * implicit.c (pattern_search): When creating a target from
2507 an implicit rule match, lookup pattern target and set precious
2508 flag in a newly created target. Fixes Savannah bug #13218.
2510 2005-05-13 Paul D. Smith <psmith@gnu.org>
2512 Implement "if... else if... endif" syntax.
2514 * read.c (eval): Push all checks for conditional words ("ifeq",
2515 "else", etc.) down into the conditional_line() function.
2516 (conditional_line): Rework to allow "else if..." clause. New
2517 return value -2 for lines which are not conditionals. The
2518 ignoring flag can now also be 2, which means "already parsed a
2519 true branch". If that value is seen no other branch of this
2520 conditional can be considered true. In the else parsing if there
2521 is extra text after the else, invoke conditional_line()
2522 recursively to see if it's another conditional. If not, it's an
2523 error. If so, raise the conditional value to this level instead
2524 of creating a new conditional nesting level. Special check for
2525 "else" and "endif", which aren't allowed on the "else" line.
2526 * doc/make.texi (Conditional Syntax): Document the new syntax.
2528 2005-05-09 Paul D. Smith <psmith@gnu.org>
2530 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2531 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2532 recurses to the w32 directory, even on non-Windows systems. Use
2533 the method suggested in the automake manual.
2534 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2535 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2537 2005-05-07 Paul D. Smith <psmith@gnu.org>
2539 * main.c (die): If we're dying with a fatal error (not that a
2540 command has failed), write back any leftover tokens before we go.
2542 * job.c (set_child_handler_action_flags): If there are jobs
2543 waiting for the load to go down, set an alarm to go off in 1
2544 second. This allows us to wake up from a potentially long-lasting
2545 read() and start a new job if the load has gone down. Turn it off
2547 (job_noop): Dummy signal handler function.
2548 (new_job): Invoke it with the new semantics.
2550 * docs/make.texi: Document secondary expansion. Various cleanups
2553 2005-05-03 Paul D. Smith <psmith@gnu.org>
2555 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2556 the targets which are to ultimately be made are called "goals";
2557 see the GNU make manual. Also, MAKECMDGOALS, etc.
2559 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2560 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2561 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2563 2005-05-02 Paul D. Smith <psmith@gnu.org>
2565 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2566 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2567 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2568 functions to vmsjobs.c. #include it into jobs.c.
2570 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2571 jobserver tokens. I found that this happens when an exported
2572 recursive variable contains a $(shell ...) function reference: in
2573 this situation we could "forget" to write back a token.
2575 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2576 we have. It's not reliable to depend on the number of children in
2577 our linked list so keep a separate count.
2578 (new_job): Check jobserver_tokens rather than children &&
2579 waiting_jobs. Increment jobserver_tokens when we get one.
2580 (free_child): If jobserver_tokens is 0, internal error. If it's
2581 >1, write a token back to the jobserver pipe (we don't write a
2582 token for the "free" job). Decrement jobserver_tokens.
2584 * main.c: Add variable master_job_slots.
2585 (main): Set it to hold the number of jobs requested if we're the
2586 master process, when using the jobserver.
2587 (die): Sanity checks: first test jobserver_tokens to make sure
2588 this process isn't holding any tokens we didn't write back.
2589 Second, if master_job_slots is set count the tokens left in the
2590 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2592 2005-04-24 Paul D. Smith <psmith@gnu.org>
2594 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2595 with -l# can lose jobserver tokens, because waiting jobs are not
2596 consulted properly when checking for the "free" token.
2598 * job.c (free_child): Count waiting_jobs as having tokens.
2599 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2600 handle jobs waiting for the load to drop.
2602 2005-04-23 Paul D. Smith <psmith@gnu.org>
2604 * main.c (main): Be careful to not core if a variable setting in
2605 the environment doesn't contain an '='. This is illegal but can
2606 happen in broken setups.
2607 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2609 2005-04-12 Paul D. Smith <psmith@gnu.org>
2611 The second expansion feature causes significant slowdown. Timing
2612 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2613 read the makefile before the feature, to 11+s to do the same
2614 operations after the feature. Additionally, memory usage
2615 increased drastically. To fix this I added some intelligence that
2616 avoids the overhead of the second expansion unless it's required.
2618 * dep.h: Add a new boolean field, need_2nd_expansion.
2620 * read.c (eval): When creating the struct dep for the target,
2621 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2622 (record_files): If there's a "%" in a static pattern rule, it gets
2623 converted to "$*" so set need_2nd_expansion to 1.
2625 * file.c (expand_deps): Rework to be more efficient. Only perform
2626 initialize_file_variables(), set_file_variables(), and
2627 variable_expand_for_file() if the need_2nd_expansion is set.
2629 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2630 (pattern_search): Ditto.
2631 * main.c (handle_non_switch_argument): Ditto.
2633 * read.c (read_all_makefiles): Ditto.
2634 (eval_makefile): Ditto.
2636 2005-04-07 Paul D. Smith <psmith@gnu.org>
2638 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2639 * variable.c (sync_Path_environment): Ditto.
2640 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2642 * main.c (main): Define the .FEATURES variable.
2643 * NEWS: Announce .FEATURES.
2644 * doc/make.texi (Special Variables): Document .FEATURES.
2646 * remake.c (check_dep): If a file is .PHONY, update it even if
2647 it's marked intermediate. Fixes Savannah bug #12331.
2649 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2651 * file.c (expand_deps): Factor out the second expansion and
2652 prerequisite line parsing logic from snap_deps().
2654 * file.c (snap_deps): Use expand_deps(). Expand and parse
2655 prerequisites of the .SUFFIXES special target first. Fixes
2656 Savannah bug #12320.
2658 2005-03-13 Paul D. Smith <psmith@gnu.org>
2660 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2663 2005-03-11 Paul D. Smith <psmith@gnu.org>
2665 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2666 available, not undefined (from Earnie Boyd).
2668 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2670 * implicit.c (pattern_search): Mark an intermediate target as
2671 precious if it happened to be a prerequisite of some (other)
2672 target. Fixes Savannah bug #12267.
2674 2005-03-09 Paul D. Smith <psmith@gnu.org>
2676 * read.c (eval_makefile): Add alloca(0).
2677 (eval_buffer): Ditto.
2679 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2681 * main.c (main): Use o_file instead of o_default when defining
2682 the .DEFAULT_TARGET special variable.
2683 * read.c (eval): Use define_variable_global() instead of
2684 define_variable() when setting new value for the .DEFAULT_TARGET
2685 special variable. Fixes Savannah bug #12266.
2687 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2689 * imlicit.c (pattern_search): Mark files for which an implicit
2690 rule has been found as targets. Fixes Savannah bug #12202.
2692 2005-03-04 Paul D. Smith <psmith@gnu.org>
2695 * doc/make.texi (Automatic Variables): Document $|.
2697 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2699 * read.c (record_files): Instead of substituting % with
2700 actual stem value in dependency list replace it with $*.
2701 This fixes stem triple expansion bug.
2703 * implicit.c (pattern_search): Copy stem to a separate
2704 buffer and make it a properly terminated string. Assign
2705 this buffer instead of STEM (which is not terminated) to
2706 f->stem. Instead of substituting % with actual stem value
2707 in dependency list replace it with $*. This fixes stem
2708 triple expansion bug.
2710 2005-03-01 Paul D. Smith <psmith@gnu.org>
2712 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2713 on Windows, as it takes a handle not a pid. Just exit.
2714 Fix from patch #3679, provided by Alessandro Vesely.
2716 * configure.in: Update check for sys_siglist[] from autoconf manual.
2717 * signame.c (strsignal): Update to use the new autoconf macro.
2719 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2721 * read.c (record_files): Add a check for the list of prerequisites
2722 of a static pattern rule being empty. Fixes Savannah bug #12180.
2724 2005-02-28 Paul D. Smith <psmith@gnu.org>
2726 * doc/make.texi (Text Functions): Update docs to allow the end
2727 ordinal for $(wordlist ...) to be 0.
2728 * function.c (func_wordlist): Fail if the start ordinal for
2729 $(wordlist ...) is <1. Matches documentation.
2730 Resolves Savannah support request #103195.
2732 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2733 previously we were stopping when !-q, exactly the opposite. This
2734 has been wrong since version 1.34, in 1994!
2735 (update_file): If we got an error don't break out to run more
2736 double-colon rules: just return immediately.
2737 Fixes Savannah bug #7144.
2739 2005-02-27 Paul D. Smith <psmith@gnu.org>
2741 * misc.c (end_of_token): Make argument const.
2742 * make.h: Update prototype.
2744 * function.c (abspath, func_realpath, func_abspath): Use
2745 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2746 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2747 * read.c (record_files): Ditto.
2748 * variable.c (do_variable_definition): Ditto.
2750 * function.c (func_error): Create a new function $(info ...) that
2751 simply prints the message to stdout with no extras.
2752 (function_table_init): Add new function to the table.
2753 * NEWS: Add $(info ...) reference.
2754 * doc/make.texi (Make Control Functions): Document it.
2756 New feature: if the system supports symbolic links, and the user
2757 provides the -L/--check-symlink-time flag, then use the latest
2758 mtime between the symlink(s) and the target file.
2760 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2761 readlink(). If both are available, define MAKE_SYMLINKS.
2762 * main.c: New variable: check_symlink_flag.
2763 (usage): Add a line for -L/--check-symlink-times to the help string.
2764 (switches): Add -L/--check-symlink-times command line argument.
2765 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2766 print a warning and disable it again.
2767 * make.h: Declare check_symlink_flag.
2768 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2769 if the file is a symlink then check each link in the chain and
2770 choose the NEWEST mtime we find as the mtime for the file. The
2771 newest mtime might be the file itself!
2772 * NEWS: Add information about this new feature.
2773 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2775 Avoid core dumps described in Savannah bug # 12124:
2777 * file.c: New variable snapped_deps remember whether we've run
2779 (snap_deps): Set it.
2780 * filedef.h: Extern it.
2781 * read.c (record_files): Check snapped_deps; if it's set then
2782 we're trying to eval a new target/prerequisite relationship from
2783 within a command script, which we don't support. Fatal.
2785 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2787 Implementation of the .DEFAULT_TARGET special variable.
2789 * read.c (eval): If necessary, update default_target_name when
2791 * read.c (record_files): Update default_target_file if
2792 default_target_name has changed.
2793 * main.c (default_target_name): Define.
2794 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2795 default_target_name is set use default_target_file as a root
2797 * filedef.h (default_target_name): Declare.
2798 * dep.h (free_dep_chain):
2799 * misc.c (free_dep_chain): Change to operate on struct nameseq
2800 and change name to free_ns_chain.
2801 * file.c (snap_deps): Update to use free_ns_chain.
2803 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2805 Implementation of the second expansion in explicit rules,
2806 static pattern rules and implicit rules.
2808 * read.c (eval): Refrain from chopping up rule's dependencies.
2809 Store them in a struct dep as a single dependency line. Remove
2810 the code that implements SySV-style automatic variables.
2812 * read.c (record_files): Adjust the code that handles static
2813 pattern rules to expand all percents instead of only the first
2814 one. Reverse the order in which dependencies are stored so that
2815 when the second expansion reverses them again they appear in
2816 the makefile order (with some exceptions, see comments in
2817 the code). Remove the code that implements SySV-style automatic
2820 * file.c (snap_deps): Implement the second expansion and chopping
2821 of dependency lines for explicit rules.
2823 * implicit.c (struct idep): Define an auxiliary data type to hold
2824 implicit rule's dependencies after stem substitution and
2827 * implicit.c (free_idep_chain): Implement.
2829 * implicit.c (get_next_word): Implement helper function for
2830 parsing implicit rule's dependency lines into words taking
2831 into account variable expansion requests. Used in the stem
2834 * implicit.c (pattern_search): Implement the second expansion
2835 for implicit rules. Also fixes bug #12091.
2837 * commands.h (set_file_variables): Declare.
2838 * commands.c (set_file_variables): Remove static specifier.
2840 * dep.h (free_dep_chain): Declare.
2841 * misc.c (free_dep_chain): Implement.
2843 * variable.h (variable_expand_for_file): Declare.
2844 * expand.c (variable_expand_for_file): Remove static specifier.
2846 * make.h (strip_whitespace): Declare.
2847 * function.c (strip_whitespace): Remove static specifier.
2849 2005-02-26 Paul D. Smith <psmith@gnu.org>
2851 * main.c (main): Check for ferror() when reading makefiles from stdin.
2852 Apparently some shells in Windows don't close pipes properly and
2855 2005-02-24 Jonathan Grant <jg@jguk.org>
2857 * configure.in: Add MinGW configuration options, and extra w32 code
2859 * Makefile.am: Add MinGW configuration options, and extra w32 code
2861 * main.c: Determine correct program string (after last \ without .exe).
2862 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2864 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2865 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2866 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2867 environment support.
2869 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2871 * function.c (func_shell): When initializing error_prefix, check
2872 that reading file name is not null. This fixes long-standing
2873 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2875 2005-02-09 Paul D. Smith <psmith@gnu.org>
2877 * maintMakefile: Update the CVS download URL to simplify them.
2878 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2879 downloading the .texi files from Savannah now.
2881 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2883 * main.c (handle_non_switch_argument): Only add variables to
2884 command_variables if they're not already there: duplicate settings
2885 waste space and can be confusing to read.
2887 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2888 this header is never included by non-WINDOWS32 code, and it
2889 requires <config.h> to define which isn't always included first.
2891 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2892 testing MINGW32 versions.
2894 * main.c (log_working_directory): flush stdout to be sure the WD
2895 change is printed before any stderr messages show up.
2897 2005-02-01 Paul D. Smith <psmith@gnu.org>
2899 * maintMakefile (po_repo): Update the GNU translation site URL.
2901 2004-12-01 Paul D. Smith <psmith@gnu.org>
2903 * main.c (main): Change char* env_shell to struct variable shell_var.
2904 * variable.c (target_environment): Use new shell_var.
2906 2004-11-30 Paul D. Smith <psmith@gnu.org>
2908 * configure.in: The old way we avoided creating build.sh from
2909 build.sh.in before build.sh.in exists doesn't work anymore; we
2910 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2911 the help!). This also keeps automake from complaining.
2912 * Makefile.am (README): Add a dummy target so automake won't
2913 complain that this file doesn't exist when we checkout from CVS.
2914 * maintMakefile (.dep_segment): Rewrite this rule since newer
2915 versions of automake don't provide DEP_FILES.
2917 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2919 Implementation of `realpath' and `abspath' built-in functions.
2921 * configure.in: Check for realpath.
2922 * function.c (abspath): Return an absolute file name that does
2923 not contain any `.' or `..' components, nor repeated `/'.
2924 * function.c (func_abspath): For each name call abspath.
2925 * function.c (func_realpath): For each name call realpath
2926 from libc or delegate to abspath if realpath is not available.
2927 * doc/make.texi (Functions for File Names): Document new functions.
2928 * doc/make.texi (Quick Reference): Ditto.
2930 2004-11-28 Paul D. Smith <psmith@gnu.org>
2932 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2933 arguments. Fixes bug #10252.
2935 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2937 * main.c (main): Set SHELL to v_noexport by default. Remember the
2938 original environment setting of SHELL in the env_shell variable.
2939 * main.h: Export new env_shell variable.
2940 * variable.c (target_environment): If we find a v_noexport
2941 variable for SHELL, add a SHELL variable with the env_shell value.
2942 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2943 * doc/make.texi (Variables/Recursion): Ditto.
2945 2004-11-28 Paul D. Smith <psmith@gnu.org>
2947 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2948 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2949 Patch by Alessandro Vesely.
2951 2004-11-12 Paul D. Smith <psmith@gnu.org>
2953 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2954 the command line if it's inside a string.
2955 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2957 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2959 * function.c (func_lastword): New function: return last word
2960 from the list of words.
2961 * doc/make.texi: Document $(lastword ). Fix broken links in
2962 Quick Reference section.
2964 2004-10-06 Paul D. Smith <psmith@gnu.org>
2966 Apply patch from Alessandro Vesely, provided with bug # 9748.
2967 Fix use of tmpnam() to work with Borland C.
2969 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2970 construction of a temporary filename, and call new function
2971 create_batch_filename().
2972 (create_batch_filename) [WINDOWS32]: New function to create a
2975 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2977 * read.c (record_target_var): Expand simple pattern-specific
2979 * variable.c (initialize_file_variables): Do not expand simple
2980 pattern-specific variable.
2982 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2984 * remake.c (update_file_1): When rebuilding makefiles inherit
2985 dontcare flag from a target that triggered update.
2987 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2989 * variable.c (initialize_file_variables): Mark pattern-specific
2990 variable as a per-target and copy export status.
2992 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2994 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2996 * implicit.c (pattern_search): When considering an implicit rule's
2997 prerequisite check that it is actually a target rather then
2998 just an entry in the file hashtable.
3000 2004-09-21 Paul D. Smith <psmith@gnu.org>
3002 * read.c (readstring): Fix some logic errors in backslash handling.
3003 (eval): Remove some unnecessary processing in buffer handling.
3004 (record_target_var): Assert that parse_variable_definition() succeeded.
3005 Reported by: Markus Mauhart <qwe123@chello.at>.
3007 * misc.c: Removed the sindex() function. All instances of this
3008 function were trivially replaceable by the standard strstr()
3009 function, and that function will always have better (or certainly
3010 no worse) performance than the very simple-minded algorithm
3011 sindex() used. This can matter with complex makefiles.
3012 * make.h: Remove the prototype for sindex().
3013 * function.c (subst_expand): Convert sindex() call to strstr().
3014 This means we no longer need to track the TLEN value so remove that.
3015 (func_findstring): Convert sindex() to strstr().
3016 * commands.c (chop_commands): Convert sindex() calls to strstr().
3017 Suggested by: Markus Mauhart <qwe123@chello.at>.
3019 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
3020 idea behind Savannah Patch #3144 from david.baird@homemail.com.
3021 If SHELL is set to CMD.EXE then assume it's batch-mode and
3022 non-unixy. I wrote the code differently from the patch, though,
3023 to make it safer. This also resolves bug #9174.
3025 2004-09-20 Paul D. Smith <psmith@gnu.org>
3027 * expand.c (variable_expand_string): Modify to invoke
3028 patsubst_expand() instead of subst_expand(); the latter didn't
3029 handle suffix patterns correctly.
3030 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
3031 was used only from variable_expand_string() and is no longer used
3033 (func_subst): Ditto, on call to subst_expand().
3034 (patsubst_expand): Require the percent pointers to point to the
3035 character after the %, not to the % itself.
3036 * read.c (record_files): New call criteria for patsubst_expand().
3037 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
3038 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
3040 2004-09-19 Paul D. Smith <psmith@gnu.org>
3042 * function.c (subst_expand): Fix a check in by_word: look for a
3043 previous blank if we're beyond the beginning of the string, not
3044 the beginning of the word.
3045 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3047 2004-05-16 Paul D. Smith <psmith@gnu.org>
3049 * remake.c (update_goal_chain): Change the argument specifying
3050 whether we're rebuilding makefiles to be a global variable,
3051 REBUILDING_MAKEFILES.
3052 (complain): Extract the code that complains about no rules to make
3053 a target into a separate function.
3054 (update_file_1): If we tried to rebuild a file during the makefile
3055 rebuild phase and it was dontcare, then no message was printed.
3056 If we then try to build the same file during the normal build,
3057 print a message this time.
3058 (remake_file): Don't complain about un-remake-able files when
3059 we're rebuilding makefiles.
3061 2004-05-11 Paul D. Smith <psmith@gnu.org>
3063 * job.c (construct_command_argv_internal): OS/2 patches from
3064 Andreas Buening <andreas.buening@nexgo.de>.
3066 2004-05-10 Paul D. Smith <psmith@gnu.org>
3068 * remake.c (update_file): Don't walk the double-colon chain unless
3069 this is a double-colon rule. Fix suggested by Boris Kolpackov
3070 <boris@kolpackov.net>.
3072 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3073 * readme.vms: New section describing OpenVMS support and issues.
3074 * default.c (default_variables): Add support for IA64.
3075 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3076 without some privilege aborts make with the error
3077 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3078 pressing Ctrl+Y and the input device is no terminal. The change
3079 catches this error and just continues.
3081 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3083 2004-04-25 Paul D. Smith <psmith@gnu.org>
3085 * commands.c (set_file_variables): Set $< properly in the face of
3086 order-only prerequisites.
3087 Patch from Boris Kolpackov <boris@kolpackov.net>
3089 2004-04-21 Bob Byrnes <byrnes@curl.com>
3091 * main.c (main): Notice failures to remake makefiles.
3093 2004-03-28 Paul D. Smith <psmith@gnu.org>
3095 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3097 * job.c: No default shell for RISC OS.
3098 (load_too_high): Hard-code the return to 1.
3099 (construct_command_argv_internal): No sh_chars or sh_cmds.
3100 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3102 2004-03-20 Paul D. Smith <psmith@gnu.org>
3104 * variable.c (do_variable_definition): Don't append from the
3105 global set if a previous non-appending target-specific variable
3106 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3109 * expand.c (reference_variable): Don't give up on variables with
3110 no value that have the target-specific append flag set: they might
3111 have a value after all. Reported by Oliver Schmidt
3112 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3113 <nikulin@dx1cmd.inp.nsk.su>.
3115 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3116 refer to absolute pathnames in directories that don't exist: some
3117 portion of the makefile could create those directories before we
3118 match the pattern. Fixes bugs #775 and #108.
3120 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3122 * main.c (main): Free makefile_mtimes if we have any.
3123 * README.W32.template: Update documentation for the current status
3124 of the MS-Windows port.
3125 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3126 environment variable is sometimes already defined which causes the
3128 * main.c (debug_signal_handler): Only define this function if
3129 SIGUSR1 is available.
3131 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3133 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3134 * README.OS2.template: Documentation updates.
3135 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3136 link line for safety.
3137 * maintMakefile (build.sh.in): Remove an extraneous ")".
3138 * job.c (child_execute_job): Close saved FDs.
3139 * job.c (exec_command) [OS/2]: exec_command(): If the command
3140 can't be exec'ed and if the shell is not Unix-sh, then try again
3141 with argv = { "cmd", "/c", ... }. Normally, this code is never
3142 reached for the cmd shell unless the command really doesn't exist.
3143 (construct_command_argv_internal) [OS/2]: The code for cmd
3144 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3145 The CMD builtin commands are case insensitive so use strcasecmp().
3147 2004-03-19 Paul D. Smith <psmith@gnu.org>
3149 * read.c (do_define): Re-order line counter increment so the count
3150 is accurate (we were losing one line per define). Reported by
3151 Dave Yost <Dave@Yost.com>.
3153 2004-03-06 Paul D. Smith <psmith@gnu.org>
3155 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3157 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3158 * misc.c (message,error,fatal): Ditto.
3159 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3160 * config.h.W32.template: Ditto.
3161 * config.h-vms.template: Ditto.
3162 * config.ami.template: Ditto.
3164 2004-03-04 Paul D. Smith <psmith@gnu.org>
3166 * README.template: Add a note about broken /bin/sh on SunOS
3167 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3169 * misc.c (message, error, fatal): Don't use "..." if we're using
3170 varargs. ansi2knr should handle this but it doesn't work: it
3171 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3172 done. On many systems (SunOS for example) va_dcl is a #define.
3173 So, force the use of the non-"..." version on pre-ANSI compilers.
3175 * maintMakefile (sign-dist): Create some rules to help automate
3176 the new GNU ftp upload method.
3178 2004-02-24 Paul D. Smith <psmith@gnu.org>
3180 * config.h.W32.template: Add HAVE_STDARG_H
3181 * config.h-vms.template: Ditto.
3182 * config.ami.template: Ditto.
3184 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3186 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3187 * build_w32.bat: Remove extra "+".
3189 2004-02-23 Paul D. Smith <psmith@gnu.org>
3191 * make.h: Create an UNUSED macro to mark unused parameters.
3192 * (many): Clean up warnings by applying UNUSED, fixing
3193 signed/unsigned incompatibilities, etc.
3195 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3197 * filedef.h: Name the command_state enumeration.
3198 * file.c (set_command_state): Use the enumeration in the function
3201 * configure.in: Explicitly set SET_MAKE to empty, to disable
3202 MAKE=make even when no make already exists. Fix bug #3823.
3204 2004-02-22 Paul D. Smith <psmith@gnu.org>
3206 * maintMakefile: Perl script to clean up all non-CVS files. Use
3207 it on all the subdirectories for the cvs-clean target.
3209 * main.c (decode_switches): Require non-empty strings for all our
3210 string command-line options. Fixes Debian bug # 164165.
3212 * configure.in: Check for stdarg.h and varargs.h.
3213 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3214 for printing messages.
3215 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3220 A number of patches for OS/2 support from Andreas Buening
3221 <andreas.buening@nexgo.de>:
3223 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3224 disable the SIGCHLD handler.
3225 (reap_children) [OS/2]: Remove special handling of job_rfd.
3226 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3227 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3228 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3229 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3230 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3233 2004-02-21 Paul D. Smith <psmith@gnu.org>
3235 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3236 <mail@kristov.de> reports that if process_begin() fails we don't
3237 handle the error condition correctly in all cases.
3238 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3239 to have a newline on the message.
3241 * job.c (construct_command_argv_internal): Add "test" to UNIX
3242 sh_cmds[]. Fixes Savannah bug # 7606.
3244 2004-02-04 Paul D. Smith <psmith@gnu.org>
3246 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3247 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3248 Hartmut Becker <Hartmut.Becker@hp.com>.
3250 2004-01-21 Paul D. Smith <psmith@gnu.org>
3252 * job.c (load_too_high): Implement an algorithm to control the
3253 "thundering herd" problem when using -l to control job creation
3254 via the load average. The system only recomputes the load once a
3255 second but we can start many jobs in a second. To solve this we
3256 keep track of the number of jobs started in the last second and
3257 apply a weight to try to guess what a correct load would be.
3258 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3259 Also fixes bug #4693.
3260 (reap_children): Decrease the job count for this second.
3261 (start_job_command): Increase the job count for this second.
3263 * read.c (conditional_line): Expand the text after ifn?def before
3264 checking to see if it's a single word. Fixes bug #7257.
3266 2004-01-09 Paul D. Smith <psmith@gnu.org>
3268 * file.c (print_file): Recurse to print all targets in
3269 double-colon rules. Fixes bug #4518, reported (with patch) by
3270 Andrew Chatham <chatham@google.com>.
3272 2004-01-07 Paul D. Smith <psmith@gnu.org>
3274 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3275 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3276 AC_FUNC_SETVBUF_REVERSED.
3278 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3279 (MAKE Variable): Fix Savannah bug #4898.
3281 * job.c (construct_command_argv_internal): Add "!" to the list of
3282 shell escape chars. POSIX sh allows it to appear before a
3283 command, to negate the exit code. Fixes bug #6404.
3285 * implicit.c (pattern_search): When matching an implicit rule,
3286 remember which dependencies have the ignore_mtime flag set.
3287 Original fix provided in Savannah patch #2349, by Benoit
3288 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3290 2003-11-22 Paul D. Smith <psmith@gnu.org>
3292 * README.W32.template (Outputs): Clarification on -j with
3293 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3296 2003-11-02 Paul D. Smith <psmith@gnu.org>
3298 * function.c (func_if): Strip all the trailing whitespace from the
3299 condition, then don't expand it. Fixed bug # 5798.
3301 * expand.c (recursively_expand_for_file): If we're expanding a
3302 variable with no file context, then use the variable's context.
3305 2003-10-21 Paul D. Smith <psmith@gnu.org>
3307 * main.c (log_working_directory): Add newlines to printf()s.
3309 * README.cvs: Add a note to ignore warnings during autoreconf.
3311 * maintMakefile (po_repo): Set a new URL for PO file updates.
3312 (get-config/config.guess get-config/config.sub): Get these files
3313 from the Savannah config project instead of ftp.gnu.org.
3315 2003-10-05 Paul Eggert <eggert@twinsun.com>
3317 * main.c (main): Avoid potential subscript error if environ has
3320 2003-08-22 Paul D. Smith <psmith@gnu.org>
3322 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3323 systems which don't yet implement the C89 standard :-/.
3325 2003-07-18 Paul D. Smith <psmith@gnu.org>
3327 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3328 [WINDOWS32]: Initialize hash.
3330 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3332 * dir.c (read_dirstream): Provide a workaround for broken versions of
3333 the MinGW dirent structure.
3335 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3337 * w32/include/dirent.h: Add __MINGW32__ filter.
3339 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3341 * make.h: Add global declaration of *make_host.
3342 * main.c (print_usage): Remove local declaration of *make_host.
3343 (print_version): Display "This program built for ..." after Copyright
3346 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3348 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3349 execution of "makeinfo --html make.texi".
3351 2003-04-30 Paul D. Smith <psmith@gnu.org>
3353 * build.template: Make some changes to maybe allow this script to
3354 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3356 * README.OS2.template: New file for OS/2 support. Original
3357 contributed by Andreas Buening.
3358 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3361 2003-04-19 Paul D. Smith <psmith@gnu.org>
3363 Fix bug #1405: allow a target to match multiple pattern-specific
3366 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3367 variable.c, where they've always belonged.
3368 * rule.h: Move the prototypes and struct pattern_var as well.
3369 * variable.c (initialize_file_variables): Invoke
3370 lookup_pattern_var() in a loop, until no more matches are found.
3371 If a match is found, create a new variable set for the target's
3372 pattern variables. Then merge the contents of each matching
3373 pattern variable set into the target's pattern variable set.
3374 (lookup_pattern_var): Change this function to be usable
3375 in a loop. It takes a starting position: if NULL, start at the
3376 beginning; if non-NULL, start with the pattern variable after that
3377 position, and return the next matching pattern.
3378 (create_pattern_var): Create a unique instance of
3379 pattern-specific variables for every definition in the makefile.
3380 Don't combine the same pattern together. This allows us to
3381 process the variable handling properly even when the same pattern
3382 is used multiple times.
3383 (parse_variable_definition): New function: break out the parsing
3384 of a variable definition line from try_variable_definition.
3385 (try_variable_definition): Call parse_variable_definition to
3387 (print_variable_data_base): Print out pattern-specific variables.
3388 * variable.h (struct variable): Remember when a variable is
3389 conditional. Also remember its flavor.
3390 (struct pattern_var): Instead of keeping a variable set, we just
3391 keep a single variable for each pattern.
3392 * read.c (record_target_var): Each pattern variable contains only a
3393 single variable, not a set, so create it properly.
3394 * doc/make.texi (Pattern-specific): Document the new behavior.
3396 2003-04-17 Paul D. Smith <psmith@gnu.org>
3398 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3399 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3400 file/directory naming rules for VMS so I can't tell whether this
3403 2003-04-09 Paul D. Smith <psmith@gnu.org>
3405 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3406 DOS-style pathnames: backslash separators and drive specifiers.
3408 2003-03-28 Paul D. Smith <psmith@gnu.org>
3410 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3411 the intermediate flag on all targets. Fixes bug #2515.
3413 2003-03-24 Paul D. Smith <psmith@gnu.org>
3415 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3416 Upgrade to autoconf 2.57 and automake 1.7.3.
3418 * job.c: More OS/2 changes from Andreas Buening.
3420 * file.c (print_file): Fix variable initialization.
3423 * remake.c (notice_finished_file):
3425 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3426 some calls (like readdir()) return NULL in valid situations
3427 without resetting errno. Fixes bug #2846.
3429 2003-02-25 Paul D. Smith <psmith@gnu.org>
3431 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3433 * job.c (_is_unixy_shell) [OS/2]: New function.
3434 Set default shell to /bin/sh.
3435 (reap_children): Close the job_rfd pipe here since we don't use a
3437 (set_child_handler_action_flags): define this to empty on OS/2.
3438 (start_job_command): Close the jobserver pipe and use
3439 child_execute_job() instead of fork/exec.
3440 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3441 rather than exec'ing, then reconfigure stdin/stdout.
3442 (exec_command): Rewrite to use spawn instead of exec. Return the
3445 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3446 in DOS. Handle the TEMP environment variable as in DOS. Don't
3447 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3448 use -j in DOS mode. Use child_execute_job() instead of
3451 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3454 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3455 prototypes that return values.
3457 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3459 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3460 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3462 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3465 2003-02-24 Paul D. Smith <psmith@gnu.org>
3467 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3468 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3469 (child_execute_job) [VMS]: Handle error status properly.
3470 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3472 * function.c (func_shell): Use EINTRLOOP() while reading from the
3473 subshell pipe (Fixes bug #2502).
3474 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3476 * main.c (main): Ditto.
3478 2003-01-30 Paul D. Smith <psmith@gnu.org>
3480 * read.c (eval): eval() was not fully reentrant, because the
3481 collapsed buffer was static. Change it to be an automatic
3482 variable so that eval() can be invoked recursively.
3484 (eval): Apply patch # 1022: fix memory reference error on long
3485 target-specific variable lines.
3486 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3488 * function.c (check_numeric): Combine the is_numeric() function
3489 into this function, since it's only called from one place.
3490 Constify this function. Have it print the incorrect string in the
3491 error message. Fixes bug #2407.
3492 (strip_whitespace): Constify.
3493 (func_if): Constify.
3494 * expand.c (expand_argument): Constify.
3496 2003-01-29 Paul D. Smith <psmith@gnu.org>
3498 Fix bug # 2169, also reported by other people on various systems.
3500 * make.h: Some systems, such as Solaris and PTX, do not fully
3501 implement POSIX-compliant SA_RESTART functionality; important
3502 system calls like stat() and readdir() can still fail with EINTR
3503 even if SA_RESTART has been set on the signal handler. So,
3504 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3505 EINTR for system calls which return -1 or 0 (NULL), respectively,
3507 Also, remove the old atomic_stat()/atomic_readdir() and
3508 HAVE_BROKEN_RESTART handling.
3510 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3512 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3513 * remake.c (touch_file): Ditto.
3515 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3516 * read.c (construct_include_path): Ditto.
3517 * remake.c (name_mtime): Ditto.
3518 * vpath.c (selective_vpath_search): Ditto.
3519 * dir.c (find_directory): Ditto.
3520 (local_stat): Ditto.
3521 (find_directory): Use ENULLLOOP() to wrap opendir().
3522 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3524 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3525 atomic_readdir() handling.
3527 2003-01-22 Paul D. Smith <psmith@gnu.org>
3529 * function.c (func_call): Fix Bug #1744. If we're inside a
3530 recursive invocation of $(call ...), mask any of the outer
3531 invocation's arguments that aren't used by this one, so that this
3532 invocation doesn't "inherit" them accidentally.
3534 2002-12-05 Paul D. Smith <psmith@gnu.org>
3536 * function.c (subst_expand): Valery Khamenia reported a
3537 pathological performance hit when doing substitutions on very
3538 large values with lots of words: turns out we were invoking
3539 strlen() a ridiculous number of times. Instead of having each
3540 call to sindex() call strlen() again, keep track of how much of
3541 the text we've seen and pass the length to sindex().
3543 2002-11-19 Paul D. Smith <psmith@gnu.org>
3545 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3548 2002-11-16 Paul D. Smith <psmith@gnu.org>
3550 * NMakefile.template (OBJS): Add hash.c object file.
3551 * SMakefile.template (srcs): Ditto.
3552 * Makefile.ami (objs): Ditto.
3553 * build_w32.bat: Ditto.
3555 * Makefile.DOS.template: Remove extra dependencies.
3557 2002-10-25 Paul D. Smith <psmith@gnu.org>
3559 * expand.c (install_variable_buffer): New function. Install a new
3560 variable_buffer context and return the previous one.
3561 (restore_variable_buffer): New function. Free the current
3562 variable_buffer context and put a previously saved one back.
3563 * variable.h: Prototypes for {install,restore}_variable_buffer.
3564 * function.c (func_eval): Push a new variable_buffer context
3565 before we eval, then restore the old one when we're done.
3568 * read.c (install_conditionals): New function. Install a new
3569 conditional context and return the previous one.
3570 (restore_conditionals): New function. Free the current
3571 conditional context and put a previously saved one back.
3572 (eval): Use the {install,restore}_conditionals for "include"
3574 (eval_buffer): Use {install,restore}_conditionals to preserve the
3575 present conditional state before we evaluate the buffer.
3578 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3580 (Recursion): Add a variable index entry for CURDIR.
3582 * README.cvs: Update to appropriate versions.
3583 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3584 don't need to copy loadavg.c: automake is smart enough to create
3585 it for me. Still have a bug in automake related to ansi2knr tho.
3587 2002-10-14 Paul D. Smith <psmith@gnu.org>
3589 * remake.c (notice_finished_file): Only touch targets if they have
3590 at least one command (as per POSIX). Resolve Bug #1418.
3592 * *.c: Convert to using ANSI C-style function definitions.
3593 * Makefile.am: Enable the ansi2knr feature of automake.
3594 * configure.in: ditto.
3596 2002-10-13 Paul D. Smith <psmith@gnu.org>
3598 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3599 for automatic variable values like $^, etc. In the case of very
3600 large lists of prerequisites this causes problems. Instead reuse
3601 a static buffer (resizeable) for each variable.
3603 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3604 target-specific variable definitions. Check for it and set an
3606 (record_target_var): Set the export field to v_export if the
3607 "exported" flag is set.
3608 * doc/make.texi (Target-specific): Document the ability to use
3611 * doc/make.texi: Change the name of the section on automatic
3612 variables from "Automatic" to "Automatic Variables". Added text
3613 clarifying the scope of automatic variables.
3615 2002-10-04 Paul D. Smith <psmith@gnu.org>
3617 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3619 (record_files): Ditto.
3621 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3622 the search for the '=' to only within the enclosing parens.
3624 2002-10-03 Paul D. Smith <psmith@gnu.org>
3626 Version 3.80 released.
3628 * dir.c: Change hash functions to use K&R function definition style.
3629 * function.c: Ditto.
3631 * variable.c: Ditto.
3633 Update to automake 1.7.
3635 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3636 (pdf): Remove this target as automake now provides one.
3638 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3640 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3642 * makefile.com: Updates for GNU make 3.80.
3643 * makefile.vms: Ditto.
3645 2002-09-23 Paul D. Smith <psmith@gnu.org>
3647 * read.c (enum make_word_type): Remove w_comment.
3648 (get_next_mword): Don't treat comment characters as special; where
3649 this function is used we will never see a comment (it's stripped
3650 before we get here) and treating comments specially means that
3651 targets like "foo\#bar" aren't handled properly.
3653 2002-09-18 Paul D. Smith <psmith@gnu.org>
3655 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3657 * read.c (eval): Expansion of arguments to export/unexport was
3658 ignoring all arguments after the first one. Change the algorithm
3659 to expand the whole line once, then parse the results.
3661 2002-09-17 Paul D. Smith <psmith@gnu.org>
3663 Fix Bug #940 (plus another bug I found while looking at this):
3665 * read.c (record_target_var): enter_file() will add a new entry if
3666 it's a double-colon target: we don't want to do that in this
3667 situation. Invoke lookup_file() and only enter_file() if it does
3668 not already exist. If the file we get back is a double-colon then
3669 add this variable to the "root" double-colon target.
3671 * variable.c (initialize_file_variables): If this file is a
3672 double-colon target but is not the "root" target, then initialize
3673 the root and make the root's variable list the parent of our
3676 2002-09-13 Paul D. Smith <psmith@gnu.org>
3678 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3680 * hash.c (round_up_2): Get rid of a warning.
3682 2002-09-12 Paul D. Smith <psmith@gnu.org>
3684 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3685 so it doesn't complain about getloadavg.c.
3687 * commands.c (set_file_variables): Make sure we always alloca() at
3688 least 1 character for the value of $? (for '\0').
3690 2002-09-11 Paul D. Smith <psmith@gnu.org>
3692 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3693 macro to use RESULT instead of the incorrect _RESULT_.
3695 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3696 and atomic_readdir(). We need to #include dirent.h to get this to
3698 * misc.c (atomic_readdir): Fix typos.
3700 2002-09-10 Paul D. Smith <psmith@gnu.org>
3702 * read.c (eval): Expand variable lists given to export and
3703 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3704 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3706 * doc/make.texi (Variables/Recursion): Document this.
3707 (Conditional Syntax): And here.
3709 2002-09-09 Paul D. Smith <psmith@gnu.org>
3711 * configure.in: Check for memmove().
3713 2002-09-07 Paul D. Smith <psmith@gnu.org>
3715 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3716 Michael Sterrett <msterret@coat.com> reports that while it has
3717 SA_RESTART, it does not work properly.
3719 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3720 that invokes stat() and loops to do it again if it returns EINTR.
3721 (atomic_readdir): Ditto, with readdir().
3723 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3724 and readdir() to atomic_stat() and atomic_readdir().
3726 2002-09-04 Paul D. Smith <psmith@gnu.org>
3728 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3729 reports that GNU make sometimes doesn't recognize that targets can
3730 be made, when directories can be created as prerequisites. He
3731 reports that changing the order of predicates in the DEP->changed
3732 flag test so that lookup_file() is always performed, solves this
3735 2002-08-08 Paul D. Smith <psmith@gnu.org>
3737 * configure.in: Require a newer version of gettext.
3739 * misc.c (perror_with_name): Translate the format string (for
3740 right-to-left language support).
3741 (pfatal_with_name): Ditto.
3743 * main.c: Create a static array of strings to store the usage
3744 text. This is done to facilitate translations.
3745 (struct command_switch): Remove argdesc and description fields.
3746 (switches): Remove values for obsolete fields.
3747 (print_usage): Print each element of the usage array.
3749 * hash.c: Change function definitions to be K&R style.
3751 2002-08-02 Paul D. Smith <psmith@gnu.org>
3753 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3754 this one because it's too hard to get right. We'll look at it for
3756 * main.c (main): Don't create the .TARGETS variable.
3757 * variable.c (handle_special_var): Don't handle .TARGETS.
3759 2002-08-01 Paul D. Smith <psmith@gnu.org>
3761 * main.c (switches): Add a new option, -B (--always-make). If
3762 specified, make will rebuild all targets that it encounters even
3763 if they don't appear to be out of date.
3764 (always_make_flag): New flag.
3765 * make.h: Extern always_make_flag.
3766 * remake.c (update_file_1): Check always_make_flag; if it's set we
3767 will always rebuild any target we can, even if none of its
3768 prerequisites are newer.
3771 * doc/make.texi (Shell Function): Make it clear that make
3772 variables marked as "export" are not passed to instances of the
3775 Add new introspection variable .VARIABLES and .TARGETS.
3777 * variable.c (handle_special_var): New function. If the variable
3778 reference passed in is "special" (.VARIABLES or .TARGETS),
3779 calculate the new value if necessary. .VARIABLES is handled here:
3780 walk through the hash of defined variables and construct a value
3781 which is a list of the names. .TARGETS is handled by
3782 build_target_list().
3783 (lookup_variable): Invoke handle_special_var().
3784 * file.c (build_target_list): Walk through the hask of known files
3785 and construct a list of the names of all the ones marked as
3787 * main.c (main): Initialize them to empty (and as simple variables).
3788 * doc/make.texi (Special Variables): Document them.
3789 * NEWS: Mention them.
3791 * variable.h (struct variable): Add a new flag "exportable" which
3792 is true if the variable name is valid for export.
3793 * variable.c (define_variable_in_set): Set "exportable" when a new
3794 variable is defined.
3795 (target_environment): Use the "exportable" flag instead of
3796 re-checking the name here... an efficiency improvement.
3798 2002-07-31 Paul D. Smith <psmith@gnu.org>
3800 * config.h-vms.template: Updates to build on VMS. Thanks to
3801 Brian_Benning@aksteel.com for helping verify the build.
3802 * makefile.com: Build the new hash.c file.
3803 * hash.h: Use strcpmi(), not stricmp(), in the
3804 HAVE_CASE_INSENSITIVE_FS case.
3806 2002-07-30 Paul D. Smith <psmith@gnu.org>
3808 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3809 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3810 Reported by <Brian_Benning@aksteel.com>.
3812 2002-07-10 Paul D. Smith <psmith@gnu.org>
3814 * variable.c (pop_variable_scope): Remove variable made unused by
3815 new hash infrastructure.
3816 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3817 comparisons as well as name comparisons.
3818 * variable.h: Add a prototype for new hash_init_function_table().
3819 * file.c (lookup_file): Remove variables made unused by new hash
3821 * dir.c (directory_contents_hash_2): Missing return of hash value.
3822 (dir_contents_file_exists_p): Remove variables made unused by new
3823 hash infrastructure.
3826 Installed Greg McGary's integration of the hash functions from the
3827 GNU id-utils package:
3829 2002-07-10 Greg McGary <greg@mcgary.org>
3831 * scripts/functions/filter-out: Add literals to to the
3832 pattern space in order to add complexity, and trigger
3833 use of an internal hash table. Fix documentation strings.
3834 * scripts/targets/INTERMEDIATE: Reverse order of files
3835 passed to expected `rm' command.
3837 2002-07-10 Greg McGary <greg@mcgary.org>

3929 2002-07-10 Paul D. Smith <psmith@gnu.org>
3931 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3932 prerequisite list. A real SysV make will expand the entire
3933 prerequisites list _twice_: we don't do that as it's a big
3934 backward-compatibility problem. We only replace those specific
3937 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3938 references left in the list of prerequisites. Check for .POSIX as
3939 we record targets, so we can disable non-POSIX behavior while
3940 reading makefiles as well as running them.
3941 (eval): Check the prerequisite list to see if we have anything
3942 that looks like a SysV prerequisite variable reference.
3944 2002-07-09 Paul D. Smith <psmith@gnu.org>
3946 * doc/make.texi (Prerequisite Types): Add a new section describing
3947 order-only prerequisites.
3949 * read.c (uniquize_deps): If we have the same file as both a
3950 normal and order-only prereq, get rid of the order-only prereq,
3951 since the normal one supersedes it.
3953 2002-07-08 Paul D. Smith <psmith@gnu.org>
3955 * AUTHORS: Added Greg McGary to the AUTHORS file.
3956 * NEWS: Blurbed order-only prerequisites.
3957 * file.c (print_file): Show order-only deps properly when printing
3960 * maintMakefile: Add "update" targets for wget'ing the latest
3961 versions of various external files. Taken from Makefile.maint in
3964 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3965 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3967 2002-07-07 Paul D. Smith <psmith@gnu.org>
3969 * po/*.po: Remove. We'll use wget to retrieve them at release
3972 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3973 rather than a shell you get an exception. Make sure we look up
3974 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3976 * remake.c (notice_finished_file): Fix handling of -t flag.
3977 Patch provided by Henning Makholm <henning@makholm.net>.
3979 * implicit.c (pattern_search): Some systems apparently run short
3980 of stack space, and using alloca() in this function caused an
3981 overrun. I modified it to use xmalloc() on the two variables
3982 which seemed like they might get large. Fixes Bug #476.
3984 * main.c (print_version): Update copyright notice to conform with
3986 (print_usage): Update help output.
3988 * function.c (func_eval): Create a new make function, $(eval
3989 ...). Expand the arguments, put them into a buffer, then invoke
3990 eval_buffer() on the resulting string.
3991 (func_quote): Create a new function, $(quote VARNAME). Inserts
3992 the value of the variable VARNAME without expanding it any
3995 * read.c (struct ebuffer): Change the linebuffer structure to an
3996 "eval buffer", which can be either a file or a buffer.
3997 (eval_makefile): Move the code in the old read_makefile() which
3998 located a makefile into here: create a struct ebuffer with that
3999 information. Have it invoke the new function eval() with that
4001 (eval_buffer): Create a new function that creates a struct ebuffer
4002 that holds a string buffer instead of a file. Have it invoke
4003 eval() with that ebuffer.
4004 (eval): New function that contains the guts of the old
4005 read_makefile() function: this function parses makefiles. Obtains
4006 data to parse from the provided ebuffer. Some modifications to
4007 make the flow of the function cleaner and clearer. Still could
4008 use some work here...
4009 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
4010 contents of the define/endef variable from the ebuffer.
4011 (readstring): Read the next line from a string-style ebuffer.
4012 (readline): Read the next line from an ebuffer. If it's a string
4013 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
4016 * dep.h (eval_buffer): Prototype eval_buffer();
4018 * variable.c (do_variable_definition): Make sure that all
4019 non-target-specific variables are registered in the global set.
4020 If we're invoked from an $(eval ...) we might be inside a $(call
4021 ...) or other function which has pushed a variable scope; we still
4022 want to define our variables from evaluated makefile code in the
4025 2002-07-03 Greg McGary <greg@mcgary.org>
4027 * dep.h (struct dep) [ignore_mtime]: New member.
4028 [changed]: convert to a bitfield.
4029 * implicit.c (pattern_search): Zero ignore_mtime.
4030 * main.c (main, handle_non_switch_argument): Likewise.
4031 * rule.c (convert_suffix_rule): Likewise.
4032 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
4033 (read_makefile): Parse '|' in prerequisite list.
4034 (uniquize_deps): Consider ignore_mtime when comparing deps.
4035 * remake.c (update_file_1, check_dep): Don't force remake for
4036 dependencies that have d->ignore_mtime.
4037 * commands.c (FILE_LIST_SEPARATOR): New constant.
4038 (set_file_variables): Don't include a
4039 prerequisite in $+, $^ or $? if d->ignore_mtime.
4042 2002-06-18 Paul D. Smith <psmith@gnu.org>
4044 * make.texinfo: Updates for next revision. New date/rev/etc.
4045 Recreate all Info menus. Change license on the manual to the GNU
4046 Free Documentation License. A number of typos.
4047 (Variables Simplify): Don't use "-" before it's defined.
4048 (Automatic Prerequisites): Rewrite the target example to work
4049 properly if the compile fails. Remove incorrect comments about
4050 how "set -e" behaves.
4051 (Text Functions): Move the "word", "wordlist", "words", and
4052 "firstword" functions here, from "File Name Functions".
4053 * make-stds.texi: Update from latest GNU version.
4054 * fdl.texi: (created) Import the latest GNU version.
4056 2002-06-06 Paul D. Smith <psmith@gnu.org>
4058 * variable.c (do_variable_definition): New function: extract the
4059 part of try_variable_definition() that actually sets the value
4060 into a separate function.
4061 (try_variable_definition): Call do_variable_definition() after
4062 parsing the variable definition string.
4063 (define_variable_in_set): Make the name argument const.
4065 * variable.h (enum variable_flavor): Make public.
4066 (do_variable_definition): Create prototype.
4068 * read.c (read_all_makefiles): Create a new built-in variable,
4070 (read_makefile): Add each makefile read in to this variable value.
4072 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4074 * Makefile.DOS.template: Tweak according to changes in the
4075 distribution. Add back the dependencies of *.o files.
4077 * configh.dos.template: Synchronize with config.h.in.
4079 2002-05-09 Paul D. Smith <psmith@gnu.org>
4081 * file.c (file_timestamp_now): Use K&R function declaration.
4083 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4084 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4085 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4086 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4087 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4088 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4089 nlist.n_name is a pointer rather than an array.
4091 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4092 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4093 * configure.in: Use it instead of the old version.
4095 * main.c (main): Prefer setvbuf() to setlinebuf().
4097 2002-05-08 Paul D. Smith <psmith@gnu.org>
4099 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4100 (loadavg_LDADD): Ditto.
4102 2002-04-29 Paul D. Smith <psmith@gnu.org>
4104 * expand.c (recursively_expand_for_file): Rename
4105 recursively_expand() to recursively_expand_for_file() and provide
4106 an extra argument, struct file. If the argument is provided, set
4107 the variable scope to that of the file before expanding.
4108 * variable.h (recursively_expand): Make this a macro that invokes
4109 recursively_expand_for_file() with a NULL file pointer.
4110 * variable.c (target_environment): Call the renamed function and
4111 provide the current file context.
4112 Fixes Debian bug #144306.
4114 2002-04-28 Paul D. Smith <psmith@gnu.org>
4116 Allow $(call ...) user-defined variables to be self-referencing
4117 without throwing an error. Allows implementation of transitive
4118 closures, among other possibly useful things.
4119 Requested by: Philip Guenther <guenther@sendmail.com>
4121 * variable.h (struct variable): Add a new field: exp_count, and
4122 new macros to hold its size and maximum value.
4123 (warn_undefined): Make this a macro.
4124 * variable.c (define_variable_in_set): Initialize it.
4125 * expand.c (recursively_expand): If we detect recursive expansion
4126 of a variable, check the exp_count field. If it's greater than 0
4127 allow the recursion and decrement the count.
4128 (warn_undefined): Remove this (now a macro in variable.h).
4129 * function.c (func_call): Before we expand the user-defined
4130 function, modify its exp_count field to contain the maximum
4131 number of recursive calls we'll allow. After the call, reset it
4134 2002-04-21 Paul D. Smith <psmith@gnu.org>
4136 Modified to use latest autoconf (2.53), automake (1.6.1), and
4137 gettext (0.11.1). We're using gettext's new "external" support,
4138 to avoid including libintl source with GNU make.
4140 * README.cvs: New file. Explain how to build GNU make from CVS.
4142 * configure.in: Modify checking for the system glob library.
4143 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4144 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4145 etc. will manage it correctly). Set an automake conditional
4146 USE_LOCAL_GLOB to decide whether to compile the glob library.
4148 * getloadavg.c (main): Include make.h in the "TEST" program to
4151 * Makefile.am: Remove special rules for loadavg. Replace them
4152 with Automake capabilities for building extra programs.
4154 * signame.c: This file does nothing if the system provide
4155 strsignal(). If not, it implements strsignal(). If the system
4156 doesn't define sys_siglist, then we make our own; otherwise we use
4158 * signame.h: Removed.
4160 * main.c (main): No need to invoke signame_init(). Update copyright.
4162 * ABOUT-NLS: Removed.
4163 * gettext.c: Removed.
4164 * gettext.h: Get a simplified copy from the gettext package.
4166 * i18n/*.po: Moved to po/.
4169 * config/*: Created. Contains package configuration helper files.
4170 * config.guess, config.sub: Moved to config directory.
4172 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4173 Rework to use new-style autoconf features. Use the "external"
4174 mode for gettext. Make the build.sh config file conditional on
4175 whether build.sh.in exists, to avoid autoconf errors.
4176 * acinclude.m4: Removed almost all macros as being obsolete.
4177 Rewrote remaining macros to use AC_DEFINE.
4178 * acconfig.h: Removed.
4180 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4181 conditional to handle customs support. Remove special handling
4184 2002-04-20 Paul D. Smith <psmith@gnu.org>
4186 * function.c (func_call): Don't mark the argument variables $1,
4187 etc. as recursive. They've already been fully expanded so
4188 there's no need to do it again, and doing so strips escaped $'s.
4189 Reported by Sebastian Glita <glseba@yahoo.com>.
4191 * remake.c (notice_finished_file): Walk through double-colon
4192 entries via the prev field, not the next field!
4193 Reported by Greg McGary <greg@mcgary.org>.
4195 * main.c (main): If the user specifies -q and asks for a specific
4196 target which is a makefile, we got an assert. In that case it
4197 turns out we should continue normally instead.
4199 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4201 * i18n/he.po: Installed a new translation.
4203 2002-01-07 Paul D. Smith <psmith@gnu.org>
4205 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4207 2001-12-04 Paul D. Smith <psmith@gnu.org>
4209 * i18n/ja.po: Installed an updated translation.
4211 2001-09-06 Paul Eggert <eggert@twinsun.com>
4213 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4214 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4216 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4218 (main): Get rid of any avoidable limit on stack size.
4220 2001-09-04 Paul D. Smith <psmith@gnu.org>
4222 * i18n/da.po: Installed an updated translation.
4224 2001-08-03 Paul D. Smith <psmith@gnu.org>
4226 * i18n/fr.po: Installed an updated translation.
4227 Resolves Debian bug #106720.
4229 2001-06-13 Paul D. Smith <psmith@gnu.org>
4231 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4234 2001-06-11 Paul D. Smith <psmith@gnu.org>
4236 * i18n/ko.po: Installed a new translation.
4238 2001-05-06 Paul D. Smith <psmith@gnu.org>
4240 Modify the EINTR handling.
4242 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4243 the way in which we manage the file descriptor/signal handler race
4244 trap to be more efficient.
4246 2001-05-06 Paul Eggert <eggert@twinsun.com>
4248 Restart almost all system calls that are interrupted, instead
4249 of worrying about EINTR. The lone exception is the read() for
4252 * configure.in (HAVE_SA_RESTART): New macro.
4253 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4254 * main.c (main): Use SA_RESTART instead of the old,
4255 nonstandard SA_INTERRUPT.
4257 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4258 * main.c (bsd_signal): New function or macro,
4259 if the implementation doesn't supply it.
4260 (The bsd_signal function will be in POSIX 1003.1-200x.)
4261 (HANDLESIG): Remove.
4262 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4264 * make.h (EINTR_SET): Remove.
4265 (SA_RESTART): New macro.
4267 * arscan.c (ar_member_touch): Don't worry about EINTR.
4268 * function.c (func_shell): Likewise.
4269 * job.c (reap_children, free_child, new_job): Likewise.
4270 * main.c (main): Likewise.
4271 * remake.c (touch_file, name_mtime): Likewise.
4273 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4274 if fstat failed with errno!=EINTR, the error was ignored.
4276 * job.c (set_child_handler_action_flags): New function.
4277 (new_job): Use it to temporarily clear the SIGCHLD action flags
4278 while reading the token.
4280 2001-05-02 Paul D. Smith <psmith@gnu.org>
4282 * job.c (start_job_command): Don't add define/endef per-line flags
4283 to the top-level flags setting.
4285 2001-04-03 Paul D. Smith <psmith@gnu.org>
4287 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4288 bit on error, so check for odd return values, not non-0 return
4290 (VMS_get_member_info): Calculate the timezone differences correctly.
4291 Reported by John Fowler <jfowler@nyx.net>.
4294 2001-03-14 Paul D. Smith <psmith@gnu.org>
4296 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4297 value before invoking define_variable().
4298 Reported by John Fowler <jfowler@nyx.net>.
4300 2001-02-07 Paul D. Smith <psmith@gnu.org>
4302 * read.c (record_target_var): If we reset the variable due to a
4303 command-line variable setting overriding it, turn off the "append"
4306 2001-01-17 Paul D. Smith <psmith@gnu.org>
4308 * variable.c (lookup_variable) [VMS]: When getting values from the
4309 environment, allocate enough space for the _value_ plus escapes,
4310 not enough space for the name plus escapes :-/.
4311 Reported by John Fowler <jfowler@nyx.net>.
4313 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4314 warnings that make generates, so it doesn't look like an error.
4315 Reported by Karl Berry <karl@gnu.org>.
4318 Fix for PR/2020: Rework appended target-specific variables. I'm
4319 fairly confident this algorithm is finally correct.
4321 * expand.c (allocated_variable_append): Rewrite. Instead of
4322 expanding each appended variable then adding all the expanded
4323 strings together, we append all the unexpanded values going up
4324 through the variable set contexts, then expand the final result.
4325 This behaves just like non-target-specific appended variable
4326 values, while the old way didn't in various corner cases.
4327 (variable_append): New function: recursively append the unexpanded
4328 value of a variable, walking from the outermost variable scope to
4330 * variable.c (lookup_variable): Remove the code that looked up the
4331 variable set list if the found variable was "append". We don't
4333 (lookup_variable_in_set): Make this non-static so we can use it
4335 (try_variable_definition): Use lookup_variable_in_set() rather
4336 than faking out current_variable_set_list by hand (cleanup).
4337 * variable.h: Add a prototype for the now non-static
4338 lookup_variable_in_set().
4340 2000-11-17 Paul D. Smith <psmith@gnu.org>
4342 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4343 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4344 before throwing a fit.
4346 2000-11-17 Paul D. Smith <psmith@gnu.org>
4348 * read.c (readline): CRLF calculations had a hole, if you hit the
4349 buffer grow scenario just right. Reworked the algorithm to avoid
4350 the need for len or lastlen at all. Problem description with
4351 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4353 2000-10-24 Paul D. Smith <psmith@gnu.org>
4355 * gettext.c (SWAP): Declare this with the prototype, otherwise
4356 some systems don't work (non-32-bit? Reported for Cray T3E).
4357 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4359 2000-10-05 Paul D. Smith <psmith@gnu.org>
4361 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4362 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4364 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4366 2000-09-22 Paul D. Smith <psmith@gnu.org>
4368 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4369 parts of the real gettext.h here, and we expect to really include
4370 the real gettext.h later. If we keep this #define, it's ignored.
4372 2000-09-21 Paul D. Smith <psmith@gnu.org>
4374 * main.c (log_working_directory): Rework the text to use complete
4375 sentences, to make life simpler for the translators.
4377 2000-08-29 Paul D. Smith <psmith@gnu.org>
4379 * file.c (remove_intermediates): Print a debug message before we
4380 remove intermediate files, so the user (if she uses -d) knows
4383 2000-08-21 Paul D. Smith <psmith@gnu.org>
4385 * variable.c (try_variable_definition): Change how we handle
4386 target-specific append variable defns: instead of just setting the
4387 value, expand it as an append _but_ only within the current
4388 target's context. Otherwise we lose all but the last value if the
4389 variable is appended more than once within the current target
4390 context. Fixes PR/1831.
4392 2000-08-16 Paul D. Smith <psmith@gnu.org>
4394 * function.c (func_shell): Nul-terminate the buffer before
4395 printing an exec error message (just in case it's not!).
4396 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4398 2000-07-25 Paul D. Smith <psmith@gnu.org>
4400 * job.c (construct_command_argv_internal): Add "~" to the list of
4401 sh_chars[] which disallow optimizing out the shell call.
4403 2000-07-23 Paul Eggert <eggert@twinsun.com>
4405 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4406 supersedes --disable-nsec-timestamps.
4407 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4408 * README: Remove --disable-nsec-timestamps.
4410 * filedef.h (struct file.low_resolution_time): New member.
4411 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4412 * remake.c (update_file_1):
4413 Avoid spurious rebuilds due to low resolution time stamps,
4414 generalizing the earlier code that applied only to archive members.
4415 (f_mtime): Archive members always have low resolution time stamps.
4417 * configure.in: Remove --disable-nsec-timestamps, as this has
4418 been superseded by .LOW_RESOLUTION_TIME.
4420 2000-07-23 Paul Eggert <eggert@twinsun.com>
4422 * configure.in (enable_nsec_timestamps): Renamed from
4423 make_cv_nsec_timestamps, since enable/disable options
4424 shouldn't be cached.
4426 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4427 and Paul Eggert <eggert@twinsun.com>
4429 * file.c (file_timestamp_now):
4430 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4431 so that clock_gettime is not linked unless needed.
4433 * filedef.h (FILE_TIMESTAMP_HI_RES):
4434 Remove definition; "configure" now does this.
4436 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4437 to before high resolution file timestamp check,
4438 since that check now uses uintmax_t.
4439 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4440 high resolution file timestamps.
4441 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4442 so that we don't link in clock_gettime unnecessarily.
4444 2000-07-17 Paul D. Smith <psmith@gnu.org>
4446 * i18n/ja.po: New version of the translation file.
4448 2000-07-07 Paul D. Smith <psmith@gnu.org>
4450 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4451 the offset calculation.
4452 (name_mtime): Replace EINTR test with EINTR_SET macro.
4454 2000-07-07 Paul Eggert <eggert@twinsun.com>
4458 * remake.c (update_file_1):
4459 Avoid spurious rebuilds of archive members due to their
4460 timestamp resolution being only one second.
4461 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4462 the clock's resolution being lower than file timestamps'.
4463 When warning about future timestamps, report only the discrepancy,
4464 not the absolute value of the timestamp and the current time.
4466 * file.c (file_timestamp_now): New arg RESOLUTION.
4467 * filedef.h (file_timestamp_now): Likewise.
4468 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4470 2000-07-05 Paul D. Smith <psmith@gnu.org>
4472 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4473 to listp. Fixes PR/1793.
4475 2000-06-26 Paul Eggert <eggert@twinsun.com>
4477 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4479 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4481 * remake.c (f_mtime): Remove unused var memtime.
4483 2000-06-25 Martin Buchholz <martin@xemacs.org>
4485 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4486 Ran spell-check on make.texinfo.
4488 2000-06-23 Paul D. Smith <psmith@gnu.org>
4490 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4491 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4492 * make.h: Define these macros.
4494 * Version 3.79.1 released.
4496 * configure.in: Add a new option, --disable-nsec-timestamps, to
4497 avoid using sub-second timestamps on systems that support it. It
4498 can lead to problems, e.g. if your makefile relies on "cp -p".
4499 * README.template: Document the issue with "cp -p".
4501 * config.guess, config.sub: Updated.
