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

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

845 2009-10-03 Paul Smith <psmith@gnu.org>
847 * make.h: Include <alloca.h> even on systems where __GNUC__ is
848 defined. Not sure why it was done the other way.

867 that caused the failure.
868 (update_file_1): Use NO_DIAG instead of DONTCARE to decide

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

929 (make_1.html): Removed.
930 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
931 (all-recursive): Allow for more than one subdir in the build
933 (mostlyclean-recursive, clean-recursive, distclean-recursive)
934 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
935 (tags-recursive): Allow for more than one subdir in the build
937 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
938 targets. Enter into doc/ to produce the targets.
939 (all-am): $(INFO_DEPS) replaced by info.
941 2009-09-26 Paul Smith <psmith@gnu.org>
943 * read.c (record_files): Use free_ns() to free struct nameseq.
946 * rule.c (freerule): Use free_dep_chain().
948 * read.c (record_files): Free FILENAMES chain for implicit rules.
949 (eval): Static pattern targets go into the string cache.
951 * function.c (string_glob): Free NAME in the nameseq chain.
953 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
955 * implicit.c (pattern_search): Terminate early if we haven't
956 found any rules to try (performance improvement).
958 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
960 * implicit.c (pattern_search): Merge three parallel arrays,
961 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
962 of struct TRYRULE. In the old version the latter two arrays
963 had insufficient length.
965 2009-09-24 Paul Smith <psmith@gnu.org>
967 * implicit.c (pattern_search): Add back support for order-only
968 prerequisites for secondary expansion implicit rules, that were
969 accidentally dropped. If we find a "|", enable order-only mode
970 and set IGNORE_MTIME on all deps that are seen afterward.
971 (pattern_search): Fix memory leaks: for intermediate files where
972 we've already set the file variable and pattern variable sets, be
973 sure to either save or free them as appropriate.
975 2009-09-23 Paul Smith <psmith@gnu.org>
977 Rework the way secondary expansion is stored, for efficiency.
978 This changes secondary expansion so that ONLY WHEN we know we have
979 a possibility of needing secondary expansion, do we defer the
980 secondary expansion. This means more parsing the deps but we use
981 a lot less memory (due to the strcache). Also, this fixes
984 * read.c (eval): Don't parse the dep string here anymore.
985 (record_files): Take the dep argument as an unparsed string. If
986 secondary expansion is enabled AND the prereq string has a '$' in
987 it, then set NEED_2ND_EXPANSION and keep the entire string.
988 Otherwise, parse the dep string here to construct the dep list
989 with the names in the strcache.
991 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
992 duplicate the name string (others are in the strcache).
994 * implicit.c: Remove struct idep and free_idep_chain(): unused.
995 (struct patdeps): New structure to store prereq information.
996 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
997 which prerequisites need expansion, and expand only those.
999 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
1000 and enter_prereqs(). split_prereqs() takes a fully-expanded string
1001 and splits it into a DEP list, handling order-only prereqs.
1002 (enter_prereqs): This function enters a list of DEPs into the file
1003 database. If there's a stem defined, expand any pattern chars.
1004 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
1005 set. Use the above functions.
1006 (snap_deps): Only perform second expansion on prereqs that need it,
1007 as defined by the NEED_2ND_EXPANSION flag.
1008 (print_prereqs): New function to print the prereqs
1009 (print_file): Call print_prereqs() rather than print inline.
1011 * hash.h (STRING_COMPARE): Take advantage of strcache() by
1013 (STRING_N_COMPARE): Ditto.
1014 (ISTRING_COMPARE): Ditto.
1016 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
1017 (parse_file_seq): Return void*
1018 * read.c (parse_file_seq): Return void*.
1019 (eval): Invoke macroized version of parse_file_seq()
1020 * default.c (set_default_suffixes): Ditto.
1021 * file.c (split_prereqs): Ditto.
1022 * function.c (string_glob): Ditto.
1023 * main.c (main): Ditto.
1024 * rule.c (install_pattern_rule): Ditto.
1026 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
1028 2009-09-16 Paul Smith <psmith@gnu.org>
1030 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
1032 * dep.h: Create alloc_dep() / free_dep() macros.
1034 * implicit.c (pattern_search): Take advantage of the new
1035 parse_file_seq() to add the directory prefix to each prereq.
1037 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
1038 all. Avoid reversing chains. Support adding prefixes.
1039 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
1040 cached/non-cached results.
1041 (eval): Remove multi_glob() & invoke new parse_file_seq().
1042 * rule.c (install_pattern_rule): Ditto.
1043 * main.c (main): Ditto.
1044 * implicit.c (pattern_search): Ditto.
1045 * function.c (string_glob): Ditto.
1046 * file.c (parse_prereqs): Ditto.
1047 * default.c (set_default_suffixes): Ditto.
1049 * variable.c (parse_variable_definition): Don't run off the end of
1050 the string if it ends in whitespace (found with valgrind).
1052 * commands.c (set_file_variables): Keep space for all targets in
1053 $? if -B is given (found with valgrind).
1055 2009-09-15 Paul Smith <psmith@gnu.org>
1057 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
1058 (xcalloc): Add new function.
1059 * make.h: New declarations.
1061 * ar.c (ar_glob_match): New calling method for concat().
1062 * main.c (main): Ditto.
1063 (decode_env_switches): Ditto.
1064 * read.c (eval_makefile): Ditto.
1065 (tilde_expand): Ditto.
1066 (parse_file_seq): Ditto.
1067 * variable.c (target_environment): Ditto.
1068 (sync_Path_environment): Ditto.
1070 * ar.c (ar_glob_match): Use xcalloc().
1071 * dir.c (file_impossible): Ditto.
1072 * file.c (enter_file): Ditto.
1073 * job.c (new_job): Ditto.
1074 * read.c (parse_file_seq): Ditto.
1075 * vmsfunctions.c (opendir): Ditto.
1077 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
1079 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
1080 inside the loop that looks up environment for PATH.
1082 2009-08-31 Eli Zaretskii <eliz@gnu.org>
1084 * function.c (windows32_openpipe): Update envp after calling
1085 sync_Path_environment.
1087 2009-08-02 Paul Smith <psmith@gnu.org>
1089 * remake.c (notice_finished_file): Ensure file->cmds is not null
1090 before looping through them. Fixes Savannah bug #21824.
1092 * doc/make.texi (Wildcard Examples): Clarify when objects is
1093 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1094 (Include): Clarify the behavior of -include.
1095 Fixes Savannah bug #18963.
1097 2009-08-01 Paul Smith <psmith@gnu.org>
1099 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1100 etc. come on the command line. Fixes Savannah bug #27093.
1102 * expand.c (expand_argument): If the argument is large enough use
1103 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1105 * variable.c (do_variable_definition): Avoid using alloca() to
1106 hold values, which can be large. Fixes Savannah bug #23960.
1108 * job.c (new_job): Use memmove() instead of strcpy() since both
1109 pointers are in the same memory block. Fixes Savannah bug #27148.
1110 Patch by Petr Machata.
1112 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1114 * job.c (construct_command_argv_internal): Add "ulimit" and
1115 "unset" to the sh_cmds for Unixy shells.
1117 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1119 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1120 that set make_cv_sys_gnu_glob, so they are also correctly set
1121 when the cache has been populated before.
1123 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1125 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1126 exist, as realpath(3) does where it's supported.
1128 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1130 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1131 (abspath): Support systems that define HAVE_DOS_PATHS (have
1132 drive letters in their file names). Use IS_PATHSEP instead of a
1133 literal '/' comparison. Fixes Savannah bug #26886.
1135 2009-06-14 Paul Smith <psmith@gnu.org>
1137 * remake.c (update_file_1): Remember the original file we marked
1138 as updating, so we can clear that flag again. If we find a target
1139 via vpath, FILE might change.
1140 (check_dep): Ditto. Fixes Savannah bug #13529.
1141 Patch by Reid Madsen <reid.madsen@tek.com>.
1143 2009-06-13 Paul Smith <psmith@gnu.org>
1145 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1146 included by MAKEFILES cannot give default goals.
1147 * read.c (eval): If set_default is not set, pass the no-default-goal
1148 value when we read included makefiles. Fixes Savannah bug #13401.
1150 * ar.c (ar_name): Ensure that targets with empty parens aren't
1151 considered archive member references: archive members must have a
1152 non-empty "member" string. Fixes Savannah bug #18435.
1154 * function.c (string_glob): Rely on multi_glob() to determine
1155 whether files exist or not. Remove call to file_exists_p() which
1156 is not always correct. Fixes Savannah bug #21231.
1157 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1158 then only files that really exist will be returned.
1159 * dep.h: Add new argument to multi_glob().
1160 * rule.c (install_pattern_rule): Ditto.
1161 * read.c (eval): Ditto.
1162 * main.c (main): Ditto.
1163 * implicit.c (pattern_search): Ditto.
1164 * file.c (parse_prereqs): Ditto.
1165 * default.c (set_default_suffixes): Ditto.
1167 2009-06-09 Paul Smith <psmith@gnu.org>
1169 * commands.c (set_file_variables): If always_make_flag is set,
1170 always add the prereq to $?. Fixes Savannah bug #17825.
1172 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1173 to rebuild the deps of all the also_make targets for that file.
1174 Fixes Savannah bug #19108.
1176 * implicit.c (pattern_search): Undo test for is_target, added by
1177 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1178 Rule Search Algorithm". Fixes Savannah bug #17752.
1180 * main.c (clean_jobserver): Clear the jobserver_fds options and
1181 set job_slots to the default when we clean up.
1182 (define_makeflags): Return the new MAKEFLAGS value.
1183 (main): Reset MAKEFLAGS in the environment when we re-exec.
1184 Fixes Savannah bug #18124.
1186 2009-06-08 Paul Smith <psmith@gnu.org>
1188 * read.c (eval): Collapse continuations post-semicolon on target-
1189 specific variables. Fixes Savannah bug #17521.
1191 2009-06-07 Paul Smith <psmith@gnu.org>
1193 * job.c (reap_children): For older systems without waitpid() (are
1194 there any of these left?) run wait(2) inside EINTRLOOP to handle
1195 EINTR errors. Fixes Savannah bug #16401.
1197 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1199 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1201 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1202 not the end, to catch second expansion $(eval ...) defining new
1203 target/prereq relationships during snap_deps.
1204 Fixes Savannah bug #24622.
1206 * read.c (record_files): The second-expansion "f->updating" hack
1207 was not completely correct: if assumed that the target with
1208 commands always had prerequisites; if one didn't then the ordering
1209 was messed up. Fixed for now to use f->updating to decide whether
1210 to preserve the last element in the deps list... but this whole
1211 area of constructing and reversing the deps list is too confusing
1212 and needs to be reworked. Fixes Savannah bug #21198.
1214 2009-06-06 Paul Smith <psmith@gnu.org>
1216 * hash.c (hash_insert): Remove useless test for NULL.
1217 Fixes Savannah bug #21823.
1219 * make.h: Move SET_STACK_SIZE determination to make.h.
1220 * main.c (main): New global variable, STACK_LIMIT, holds the
1221 original stack limit when make was started.
1222 * job.c (start_job_command): Reset the stack limit, if we changed it.
1223 Fixes Savannah bug #22010.
1225 * remake.c (check_dep): Only set the target's state to not-started
1226 if it's not already running. Found this while testing -j10 builds
1227 of glibc: various targets were being rebuilt multiple times.
1228 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1231 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1232 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1235 2009-06-04 Paul Smith <psmith@gnu.org>
1237 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1239 * maintMakefile: Modify access of config and gnulib Savannah
1240 modules to use GIT instead of CVS.
1242 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1243 Fixes Savannah bug #24655.
1245 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1246 this can happen during some invocations of $(eval ...) for example.
1247 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1249 2009-06-02 Paul Smith <psmith@gnu.org>
1251 * configure.in: Check for fileno()
1252 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1253 for the makefile file so invocations of $(shell ...) don't inherit it.
1254 Fixes Savannah bug #24277.
1256 2009-06-01 Paul Smith <psmith@gnu.org>
1258 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1259 expansion was handled incorrectly. Rework the default goal
1260 handling to save the variable only. Remove default_goal_file and
1262 * read.c (eval): Check default_goal_var, not default_goal_name.
1263 * read.c (record_target_var): Don't check default_goal_file here.
1265 2009-05-31 Paul Smith <psmith@gnu.org>
1267 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1268 it, and if the multi_glob() returns nothing (say it expanded to
1269 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1271 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1272 $(and ..) to the reference. Fixes Savannah bug #25694.
1274 * make.1: Be clear that some recipes will be executed even with -n.
1275 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1277 * doc/make.texi (Override Directive): Make more clear how
1278 overrides and appends interact.
1279 Elucidates part of Savannah bug #26207.
1281 * read.c (record_target_var): Don't reset the origin on
1282 target-specific variables; try_variable_definition() will handle
1283 this correctly. Fixes Savannah bug #26207.
1285 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1286 Fixes Savannah bug #25712.
1288 * implicit.c (pattern_search): Keep a pointer to the beginning of
1289 the filename and save that instead of the constructed pointer.
1290 Fixes Savannah bug #26593.
1291 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1293 2009-05-30 Paul Smith <psmith@gnu.org>
1295 * doc/make.texi (Multi-Line): Add a description of the new abilities
1296 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1297 "command sequence" vs. "recipe" syntax.
1298 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1299 after a define, to create variables with those flavors.
1301 2009-05-25 Paul Smith <psmith@gnu.org>
1303 Reworked the parser for variable assignments to allow multiple
1304 modifiers, and in any order. Also allows variable and
1305 prerequisites to be modifier names ('export', 'private', etc.)
1307 * NEWS: Add notes about user-visible changes.
1309 * read.c (struct vmodifiers): Remember what modifiers were seen.
1310 (parse_var_assignment): New function to parse variable assignments.
1311 (eval): Call the new function. Handle variable assignments earlier.
1313 * variable.c (parse_variable_definition): Only parse; don't create var.
1314 (assign_variable_definition): Call parse, then create the var.
1316 2009-05-24 Paul Smith <psmith@gnu.org>
1318 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1319 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1321 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1323 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1324 Fixes Savannah bug #25412.
1326 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1327 prototype for xmalloc.
1328 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1329 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1330 Loop over an array of extensions, instead of duplicating the same
1331 code inline. Use SearchPath followed by CreateFile, instead of
1332 the obsolete OpenFile. Fixes Savannah bug #17277.
1333 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1334 to `find_file'. Fixes Savannah bug #25662.
1336 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1338 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1339 Fixes Savannah bug #20495.
1341 2009-02-28 Ralf Wildenhues <address@hidden>
1343 * doc/make.texi (Instead of Execution): Document interaction of
1344 -t with phony targets.
1346 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1348 Introduce a new keyword "private" which applies to target-specific
1349 variables and prevents their values from being inherited.
1351 * variable.h (struct variable): Add private_var flag to each variable.
1352 Add a flag to specify which list entry switches to the parent target.
1353 * variable.c (define_variable_in_set): Initialize private_var flag.

1372 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1374 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1377 * w32/subproc/build.bat (GCCBuild): Likewise.
1379 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1381 * job.c (construct_command_argv_internal): Avoid extra backslash
1382 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1385 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1387 * README.W32.template: Remove obsolete text about non-support for
1388 -jN without Unixy shell. Remove obsolete text about not supplying
1389 Visual Studio project files (we do supply them). Modify text to
1390 prefer GCC builds to MSC builds.
1392 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1394 * doc/make.texi (Empty Targets): Fix typo.

1409 `value' field is NULL.
1411 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1413 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1415 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1416 (TEXINFOS): Value changed to `doc/make.texi'.
1417 (.SUFFIXES): Use .texi instead of .texinfo.
1418 (make.info, make.dvi): Depend on doc/make.texi.
1419 (.texi.info): New target, instead of ".texinfo.info". Change -I
1420 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1421 (.texi): New target, instead of ".texinfo". Change -I switch to
1422 $(MAKEINFO) to look in doc/. Use --no-split.
1423 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1424 switch to $(MAKEINFO) to look in doc/.
1425 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1426 "*.i[0-9][0-9]" (due to --no-split above).

1428 (html, make_1.html): New targets.
1429 (.PHONY): Add "html".

1435 HAVE_DECL_SYS_SIGLIST.
1437 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1438 build does not use child_execute_job.
1440 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1441 export the SHELL environment variable to the child.
1443 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1445 * config.h.W32: Include sys/types.h.
1446 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1448 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH

1462 * remake.c (f_mtime): Print time difference values between 100 and
1463 ULONG_MAX in fixed-point notation rather than in exponention notation.
1465 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1467 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1468 a more complex value than a simple shell: if it's not a default
1469 shell now then expand it and see if is a default shell then.
1471 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1473 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1474 pathnames, with const strings.
1475 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1476 from the template (used for building from CVS, not a dist).
1478 2007-10-10 Paul Smith <psmith@gnu.org>
1480 * make.h: Add a prototype for w32_kill() (change suggested by
1481 Yongwei Wu <wuyongwei@gmail.com>).
1483 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1485 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1486 directories in Path.
1488 2007-09-12 Paul Smith <psmith@gnu.org>

1491 Provided by Diego Biurrun <diego@biurrun.de>
1492 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1493 Provided by Diego Biurrun <diego@biurrun.de>
1495 2007-09-11 Paul Smith <psmith@gnu.org>
1497 * doc/make.texi (Special Variables): Moved this into the "How to
1498 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1499 (MAKEFILE_LIST) No longer a section; this was added into the
1500 "Special Variables" section.
1501 (Rule Introduction): Reference .RECIPEPREFIX.
1502 (Simple Makefile): Ditto.
1503 (Rule Syntax): Ditto.
1504 (Command Syntax): Ditto.
1505 (Error Messages): Ditto.
1507 2007-09-10 Paul Smith <psmith@gnu.org>
1509 * commands.c (print_commands): Don't print an extra line in the
1510 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1512 * read.c (construct_include_path): Add the full string to the cache; we
1513 were chopping the last char.
1515 * NEWS: Announce the .RECIPEPREFIX special variable.
1516 * variable.c (lookup_special_var): Rename from handle_special_var().
1517 (lookup_variable): Call the new name.
1518 (set_special_var): New function: handle setting of special variables.
1519 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1520 (do_variable_definition): Call it.
1521 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1522 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1523 * main.c (main): Create the .RECIPEPREFIX special variable.
1524 * read.c (eval): Remove the cmd_prefix characters from the command
1525 scripts here, so they're not stored in the commands array at all,
1526 rather than waiting and stripping them out during command construction.
1527 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1529 2007-08-15 Paul Smith <psmith@gnu.org>
1531 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1532 file has had the section info removed, so add some to make.texi
1533 before we include it.
1535 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1537 * remake.c (check_dep): Reset the target state for intermediate
1538 files. They might have been considered before but not updated
1539 then (order-only for example) but they will be this time.
1540 Fixes Savannah bug #'s 3330 and 15919.
1542 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1544 Fix Savannah bug #20549:
1545 * function.c (func_shell): Call construct_command_argv with zero
1547 * job.c (construct_command_argv_internal): New argument FLAGS; all
1549 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1551 * job.h (construct_command_argv_internal): Update prototype.
1553 2007-07-13 Paul Smith <psmith@gnu.org>
1555 * file.c (expand_deps): Use variable_buffer as the start of the
1556 buffer, not the original pointer (in case it was reallocated).
1557 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1558 Fixes Savannah bug #20452.
1560 2007-07-04 Paul Smith <psmith@gnu.org>
1562 * (ALL FILES): Update to GPLv3.
1563 * (ALL FILES): Update copyright for 2007.

1573 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1574 "Expansion of a deferred"
1575 Fixes Savannah bug #20018.
1577 * expand.c (variable_expand_for_file): Preserve the value of
1578 reading_file rather than setting it to 0 at the end.

1581 2007-05-11 Paul Smith <psmith@gnu.org>
1583 * job.c (new_job): Add debug info to specify where make found the
1584 command script it is running to build a target.
1585 Fixes Savannah bug #18617.

1595 Dave Korn <dave.korn@artimi.com>
1597 2007-05-08 Paul Smith <psmith@gnu.org>
1599 Fix Savannah bug #19656:
1601 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1603 * make.h: Change all case-insensitive string compares to use
1604 strcasecmp() (from POSIX). If we don't have that but do have one
1605 of the others, define strcasecmp to be one of those instead. If
1606 we don't have any, declare a prototype for our own version.
1608 * misc.c (strcasecmp): Use this if we can't find any native
1609 case-insensitive string comparison function.
1610 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1611 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1613 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1614 strcasecmp() instead of stricmp().
1615 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1616 instead of strcmpi().
1617 * acinclude.m4: Remove the strcasecmp() check from here.
1619 2007-03-21 Paul Smith <psmith@gnu.org>
1621 * configure.in: Don't turn on case-insensitive file system support
1622 if --disable-... is given. Fixes Savannah bug #19348.
1624 2007-03-19 Paul Smith <psmith@gnu.org>
1626 * ALL: Use the strcache for all file name strings, or other
1627 strings which we will never free. The goal is to save memory by
1628 avoiding duplicate copies of strings. However, at the moment this
1629 doesn't save much memory in most situations: due to secondary
1630 expansion we actually save prerequisite lists twice (once before
1631 the secondary expansion, and then again after it's been parsed
1632 into individual file names in the dep list). We will resolve this
1633 in a future change, by doing the parsing up-front for targets
1634 where secondary expansion is not set.
1636 Moving things into the strcache also allows us to use const
1637 pointers in many more places.
1639 2007-01-03 Paul Smith <psmith@gnu.org>
1641 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1642 the function, not just the first. Fixes Savannah bug #18680.
1644 2006-11-18 Paul Smith <psmith@gnu.org>
1646 * strcache.c (strcache_add_len): Don't allocate a new buffer
1647 unless the string is not already nil-terminated. Technically this
1648 is a violation of the standard, since we may be passed an array
1649 that is not long enough to test one past. However, in make this
1650 is never true since we only use nil-terminated strings or
1651 sub-strings thereof.
1653 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1655 * main.c: New global cmd_prefix, defaults to '\t'.
1656 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1659 * dir.c: Constified.
1660 (dir_contents_file_exists_p): Check for an error return from
1661 readdir(), just in case.
1663 * commands.c: Constified.
1664 * default.c: Constified.
1665 * expand.c: Constified.
1666 * function.c: Partial constification.

1671 * w32/pathstuff.c: Partial constification.
1673 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1675 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1676 backslashes and drive letters as absolute.
1678 2006-10-22 Paul Smith <psmith@gnu.org>

1682 2006-10-21 Paul Smith <psmith@gnu.org>
1685 * arscan.c: Constified.
1687 2006-09-30 Paul Smith <psmith@gnu.org>
1689 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1690 point to lastword since the example was updated.
1691 Fixes Savannah bug #16304.
1692 (Secondary Expansion): Correct example description.
1693 Fixes Savannah bug #16468.
1694 (Makefile Contents): Clarify that comments cannot appear within
1695 variable references or function calls.
1696 Fixes Savannah bug #16577.
1697 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1698 Fixes Savannah bug #17701.
1699 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1701 prerequisites. Fixes Savannah bug #17880.
1702 (Rule Syntax): "lise" -> "list"
1703 (Multiple Rules): ... -> @dots{}
1704 (Splitting Lines): ditto.
1706 * remake.c (update_file_1): Prereqs that don't exist should be
1707 considered changed, for the purposes of $?.
1708 Fixes Savannah bug #16051.

1750 that don't have extended grep.
1751 (cvsclean): Use $(PERL) instead of perl.

1755 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1757 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1758 inner-scope variables don't mask outer-scope variables.

1821 2006-03-23 Paul D. Smith <psmith@gnu.org>
1823 * configure.in: Look for build.sh.in in $srcdir so it will be
1824 built for remote configurations as well.
1826 * Makefile.am: Make sure to clean up build.sh during distclean.
1827 Fixes Savannah bug #16166.
1829 * misc.c (log_access): Takes a const char *.

1835 * implicit.c (pattern_search): Call set_file_variables only
1836 if we have prerequisites that need second expansion. Fixes
1837 Savannah bug #16140.
1839 2006-03-19 Paul D. Smith <psmith@gnu.org>
1841 * remake.c (update_file): Add alloca(0) to clean up alloca'd

1857 allow multiple concurrent runs.
1858 Patch from Joseph Myers <joseph@codesourcery.com>
1860 2006-03-17 Boris Kolpackov <boris@kolpackov.net>

1864 (copy_dep_chain): Copy stem.
1865 (free_dep_chain): Use free_dep.
1866 * read.c (record_files): Store stem in the dependency line.
1867 * file.c (expand_deps): Use stem stored in the dependency line. Use
1868 free_dep_chain instead of free_ns_chain.

1881 Fixes Savannah bug #15913.
1883 2006-03-09 Paul Smith <psmith@gnu.org>
1885 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1886 listed non-existent files as changed. Turns out there's a bug in
1887 the Linux kernel builds which means that this change causes
1888 everything to rebuild every time. We will re-introduce this fix
1889 in the next release, to give them time to fix their build system.
1890 Fixes Savannah bug #16002.
1891 Introduces Savannah bug #16051.

1908 2006-02-19 Paul D. Smith <psmith@gnu.org>
1910 * commands.c (set_file_variables): Realloc, not malloc, the static
1911 string values to avoid memory leaks.
1913 * expand.c (recursively_expand_for_file): Only set reading_file to
1914 an initialized value.
1916 * implicit.c (pattern_search): We need to make a copy of the stem
1917 if we get it from an intermediate dep, since those get freed.
1919 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1921 (enter_file) [VMS]: Ditto.

1928 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1929 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1930 the calls to _beginthreadex.
1932 * expand.c (recursively_expand_for_file): Initialize `save' to
1933 prevent compiler warnings.
1935 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1937 * job.c (construct_command_argv_internal): Don't create a temporary
1938 script/batch file if we are under -n. Call _setmode to switch the
1939 script file stream to text mode.

1943 * variable.c (merge_variable_set_lists): Don't try to merge the
1944 global_setlist. Not only is this useless, but it can lead to
1945 circularities in the linked list, if global_setlist->next in one
1946 list gets set to point to another list which also ends in

1952 Fix for Savannah bug #106.

1955 expanding. If no variable is being expanded, it's the same as
1957 * make.h (expanding_var): Declare it.
1958 * expand.c (recursively_expand_for_file): Set expanding_var to the
1959 current variable we're expanding, unless there's no file info in
1960 it (could happen if it comes from the command line or a default
1961 variable). Restore it before we exit.

1973 * read.c (eval): Even if the included filenames expands to the
1974 empty string we still need to free the allocated buffer.
1976 * implicit.c (pattern_search): If we allocated a variable set for
1977 an impossible file, free it.
1978 * variable.c (free_variable_set): New function.
1979 * variable.h: Declare it.
1981 * read.c (read_all_makefiles): Makefile names are kept in the
1982 strcache, so there's never any need to alloc/free them.
1985 * main.c (main): Add "archives" to the .FEATURES variable if
1986 archive support is enabled.
1987 * doc/make.texi (Special Variables): Document it.

1997 * (ALL FILES): Updated copyright and license notices.
1999 2006-02-10 Paul D. Smith <psmith@gnu.org>
2001 A new internal capability: the string cache is a read-only cache
2002 of strings, with a hash table interface for fast lookup. Nothing
2003 in the cache will ever be freed, so there's no need for reference
2004 counting, etc. This is the beginning of a full solution for
2005 Savannah bug #15182, but for now we only store makefile names here.
2007 * strcache.c: New file. Implement a read-only string cache.
2008 * make.h: Add prototypes for new functions.
2009 * main.c (initialize_global_hash_tables): Initialize the string cache.
2010 (print_data_base): Print string cache stats.
2011 * read.c (eval_makefile): Use the string cache to store makefile
2012 names. Rewrite the string allocation to be sure we free everything.

2016 * dir.c (dir_contents_file_exists_p): Don't opendir if the
2017 directory time stamp didn't change, except on FAT filesystems.

2042 -W, don't overwrite it with the real mtime.

2063 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
2064 the comparison. For 64-bits systems the result of the subtraction
2065 might not fit into an int. Use comparison instead.
2066 Fixes Savannah bug #15534.
2068 * doc/make.texi: Update the chapter on writing commands to reflect
2069 the changes made in 3.81 for backslash/newline and SHELL handling.
2071 2006-02-01 Paul D. Smith <psmith@gnu.org>

2089 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2091 * remake.c (update_goal_chain): Set g->changed instead of
2092 incrementing it, as it is only 8-bit wide, and could overflow if
2093 many commands got started in update_file.
2095 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
2097 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
2098 MAXIMUM_WAIT_OBJECTS.
2099 (process_wait_for_any_private): Change dimension of handles[]
2100 array to MAXIMUM_WAIT_OBJECTS.
2101 (process_used_slots): New function.
2102 (process_register): Don't register more processes than the
2103 available number of slots.
2104 (process_easy): Don't start new processes if all slots are used up.
2106 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
2107 are already more children than sub_proc.c can handle, behave as if
2108 the load were too high.
2109 (start_job_command): Fix a typo in error message when process_easy
2112 2006-01-14 Eli Zaretskii <eliz@gnu.org>
2114 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
2115 the shell is not sh.exe.
2117 * job.c (create_batch_file): Renamed from create_batch_filename;
2118 all callers changed. Don't close the temporary file; return its
2119 file descriptor instead. New arg FD allows to return the file
2121 (construct_command_argv_internal): Use _fdopen instead of fopen to
2122 open the batch file.
2124 2006-01-04 Paul D. Smith <psmith@gnu.org>
2126 * readme.vms: Updates for case-insensitive VMS file systems from
2127 Hartmut Becker <Hartmut.Becker@hp.com>.
2128 * dir.c (vms_hash): Ditto.
2129 * vmsify.c (copyto): Ditto.
2130 * vmsfunctions.c (readdir): Ditto.
2132 * make.1: Add a section on the exit codes for make.
2134 * doc/make.texi: A number of minor updates to the documentation.
2136 2006-01-03 Paul D. Smith <psmith@gnu.org>
2138 * remake.c (update_file_1): Mark a prerequisite changed if it
2141 * read.c (eval): Be sure to strip off trailing whitespace from the
2142 prerequisites list properly. Also, initialize all fields in
2143 struct dep when creating a new one.
2145 2005-12-28 Paul D. Smith <psmith@gnu.org>
2147 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2148 disable warnings for MSC.
2149 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2151 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2153 * doc/make.texi (Execution): Add a footnote about changes in
2154 handling of backslash-newline sequences. Mention the differences
2155 on MS-DOS and MS-Windows.
2157 * NEWS: More details about building the MinGW port and a pointer
2158 to README.W32. Fix the section name that describes the new
2159 backward-incompatible processing of backslash-newline sequences.
2160 The special processing of SHELL set to "cmd" is only relevant to
2161 MS-Windows, not MS-DOS.
2163 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2165 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2166 to DWORD, to avoid compiler warnings.
2167 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2168 use %ld in format, to avoid compiler warnings.
2170 * doc/make.texi (Special Targets): Fix a typo.
2171 (Appending): Fix cross-reference to Setting.
2172 (Special Variables, Secondary Expansion, File Name Functions)
2173 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2174 periods after a sentence.
2175 (Execution): Add @: after "e.g.".
2176 (Environment): Fix punctuation.
2177 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2178 (Shell Function, Target-specific): Add @: after "vs."
2180 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2182 * read.c (record_target_var): Initialize variable's export field
2183 with v_default instead of leaving it "initialized" by whatever
2184 garbage happened to be on the heap.
2186 2005-12-12 Paul D. Smith <psmith@gnu.org>
2188 * make.1: Fix some display errors and document all existing options.
2189 Patch by Mike Frysinger <vapier@gentoo.org>.
2191 2005-12-11 Paul D. Smith <psmith@gnu.org>
2193 * implicit.c (pattern_search): If 2nd expansion is not set for
2194 this implicit rule, replace the pattern with the stem directly,
2195 and don't re-expand the variable list. Along with the other
2196 .SECONDEXPANSION changes below, fixes bug #13781.
2198 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2200 * implicit.c (pattern_search): Mark other files that this rule
2201 builds as targets so that they are not treated as intermediates
2202 by the pattern rule search algorithm. Fixes bug #13022.
2204 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2206 * remake.c (notice_finished_file): Propagate the change of
2207 modification time to all the double-colon entries only if
2208 it is the last one to be updated. Fixes bug #14334.
2210 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2212 * function.c (func_flavor): Implement the flavor function which
2213 returns the flavor of a variable.
2214 * doc/make.texi (Functions for Transforming Text): Document it.
2215 * NEWS: Add it to the list of new functions.
2217 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2219 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2221 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2222 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2224 2005-10-26 Paul Smith <psmith@gnu.org>
2226 * read.c (record_files): Don't set deps flags if there are no deps.
2227 * maintMakefile: We only need to build the templates when we are
2228 creating a distribution, so don't do it for "all".
2230 2005-10-24 Paul D. Smith <psmith@gnu.org>
2232 Make secondary expansion optional: its enabled by declaring the
2233 special target .SECONDEXPANSION.
2235 * NEWS: Update information on second expansion capabilities.
2236 * doc/make.texi (Secondary Expansion): Document the
2237 .SECONDEXPANSION special target and its behavior.
2238 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2239 prerequisite list was found in a static pattern rule.
2240 (free_dep_chain): Declare a prototype.
2241 * file.c (parse_prereqs): New function: break out some complexity
2243 (expand_deps): If we aren't doing second expansion, replace % with
2244 the stem for static pattern rules. Call the new function.
2245 * filedef.h (parse_prereqs): Declare a prototype.
2246 * implicit.c (pattern_search): Initialize the new staticpattern
2248 * main.c (second_expansion): Declare a global variable to remember
2249 if the special target has been seen. Initialize the new
2250 staticpattern field for prerequisites.
2251 * make.h: Extern for second_expansion.
2252 * misc.c (free_dep_chain): New function: frees a struct dep list.
2253 * read.c (read_all_makefiles): Initialize the staticpattern field.
2254 (eval_makefile): Ditto.
2255 (record_files): Check for the .SECONDEXPANSION target and set
2256 second_expansion global if it's found.
2257 Use the new free_dep_chain() instead of doing it by hand.
2258 Set the staticpattern field for prereqs of static pattern targets.
2260 2005-10-16 Paul D. Smith <psmith@gnu.org>
2262 * main.c (main): Set CURDIR to be a file variable instead of a
2263 default, so that values of CURDIR inherited from the environment
2264 won't override the make value.
2266 2005-09-26 Paul D. Smith <psmith@gnu.org>
2268 * job.c (construct_command_argv_internal): If the line is empty
2269 remember to free the temporary argv strings.
2272 2005-09-16 Paul D. Smith <psmith@gnu.org>
2274 * job.c (start_job_command): The noerror flag is a boolean (single
2275 bit); set it appropriately.
2276 Reported by Mark Eichin <eichin@metacarta.com>
2278 2005-08-29 Paul D. Smith <psmith@gnu.org>
2280 * function.c (func_error): On Windows, output from $(info ...)
2281 seems to come in the wrong order. Try to force it with fflush().
2283 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2285 * read.c (record_files): Move code that sets stem for static
2286 pattern rules out of the if (!two_colon) condition so it is
2287 also executed for two-colon rules. Fixes Savannah bug #13881.
2289 2005-08-08 Paul D. Smith <psmith@gnu.org>
2291 * make.h: Don't test that __STDC__ is non-0. Some compilers
2292 (Windows for example) set it to 0 to denote "ISO C + extensions".
2295 2005-08-07 Paul D. Smith <psmith@gnu.org>
2297 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2298 conditional (slightly different version of a fix from Eli).
2300 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2301 If make is running in parallel without -k and two jobs die in a
2302 row, but not too close to each other, then make will quit without
2303 waiting for the rest of the jobs to die.
2305 * main.c (die): Don't reset err before calling reap_children() the
2306 second time: we still want it to be in the error condition.
2307 * job.c (reap_children): Use a static variable, rather than err,
2308 to control whether or not the error message should be printed.
2310 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2312 * w32/subproc/sub_proc.c: Include signal.h.
2313 (process_pipe_io, process_file_io): Pass a pointer to a local
2314 DWORD variable to GetExitCodeProcess. If the exit code is
2315 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2317 * job.c [WINDOWS32]: Include windows.h.
2318 (main_thread) [WINDOWS32]: New global variable.
2319 (reap_children) [WINDOWS32]: Get the handle for the main thread
2320 and store it in main_thread.
2322 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2323 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2324 doing anything else. When we are done, close the main thread
2325 handle and exit with status 130.
2327 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2329 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2332 * main.c (find_and_set_default_shell): If found a DOSish shell,
2333 set sh_found and the value of default_shell, and report the
2334 findings in debug mode.
2336 * job.c (construct_command_argv_internal): Check unixy_shell, not
2337 no_default_sh_exe, to decide whether to use Unixy or DOSish
2340 * README.W32: Update with info about the MinGW build.
2342 * build_w32.bat: Support MinGW.
2344 * w32/subproc/build.bat: Likewise.
2346 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2347 printing DWORD args.
2349 * function.c (windows32_openpipe): Fix format strings for printing
2352 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2354 (start_job_command): Fix format string for printing the result of
2356 (start_job_command) [WINDOWS32]: Do not define.
2357 (exec_command): Fix format string for printing HANDLE args.
2359 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2360 to avoid compiler warnings.
2361 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2362 (Note: some of these fixes were submitted independently by J. Grant)
2364 2005-07-30 J. Grant <jg@jguk.org>
2366 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2367 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2368 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2370 2005-07-15 Paul Smith <psmith@gnu.org>
2372 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2373 we don't have a POSIX shell, then revert to the old
2374 backslash-newline behavior (where they are stripped).
2377 2005-07-08 Paul D. Smith <psmith@gnu.org>
2379 * config.h.W32.template: Reorder to match the standard config.h,
2380 for easier comparisons.
2381 From J. Grant <jg@jguk.org>
2383 * maintMakefile: Remove .dep_segment before overwriting it, in
2384 case it's not writable or noclobber is set.
2385 * expand.c (variable_expand_string): Cast result of pointer
2386 arithmetic to avoid a warning.
2387 * main.c (switches): Add full-fledged final initializer.
2389 2005-07-06 Paul D. Smith <psmith@gnu.org>
2391 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2392 * signame.c (strsignal): If we found _sys_siglist[] or
2393 __sys_siglist[] use those instead of sys_siglist[].
2394 From Albert Chin <china@thewrittenword.com>
2396 2005-07-04 Paul D. Smith <psmith@gnu.org>
2398 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2399 globfree(); set up to use the GNU versions.
2400 From Martin Zinser <zinser@zinser.no-ip.info>
2402 2005-07-03 Paul D. Smith <psmith@gnu.org>
2404 From J. Grant <jg@jguk.org>:
2406 * README.W32.template: Update the Windows and tested MSVC versions.
2407 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2408 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2409 * build_w32.bat: Ditto.
2410 * w32/subproc/build.bat: Ditto.
2412 2005-06-28 Paul D. Smith <psmith@gnu.org>
2414 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2415 declaration was checked but not present.
2417 2005-06-27 Paul D. Smith <psmith@gnu.org>
2419 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2420 to unsigned long. Fixes Savannah bug #13550.
2422 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2423 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2424 Fixes Savannah bug #13551.
2426 2005-06-26 Paul D. Smith <psmith@gnu.org>
2428 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2429 it if ANSI_STRING is not set.
2431 2005-06-25 Paul D. Smith <psmith@gnu.org>
2433 * read.c (eval): If no filenames are passed to any of the
2434 "include" variants, don't print an error.
2435 * doc/make.texi (Include): Document this.
2436 Fixes Savannah bug #1761.
2438 * job.c (construct_command_argv_internal): Sanitize handling of
2439 backslash/newline pairs according to POSIX: that is, keep the
2440 backslash-newline in the command script, but remove a following
2441 TAB character, if present. In the fast path, make sure that the
2442 behavior matches what the shell would do both inside and outside
2443 of quotes. In the slow path, quote the backslash and put a
2444 literal newline in the string.
2445 Fixes Savannah bug #1332.
2446 * doc/make.texi (Execution): Document the new behavior and give
2448 * NEWS: Make a note of the new behavior.
2450 * make.h [WINDOWS32]: #include <direct.h>.
2451 Fixes Savannah bug #13478.
2453 * remake.c (name_mtime): If the stat() of a file fails and the -L
2454 option was given and the file is a symlink, take the best mtime of
2455 the symlink we can get as the mtime of the file and don't fail.
2456 Fixes Savannah bug #13280.
2458 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2459 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2460 inside a variable reference. Make this function static as it's
2462 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2463 parsing an unexpanded line looking for semicolons.
2464 Fixes Savannah bug #1454.
2465 * misc.c (remove_comments): Move this to read.c and make it static
2466 as it's only used there. Call find_char_unquote() with new arg.
2467 * make.h: Remove prototypes for find_char_unquote() and
2468 remove_comments() since they're static now.
2470 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2471 its export flag and obtain its value. When we need to re-exec,
2472 increment the value and add it into the environment.
2473 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2474 * NEWS: Mention MAKE_RESTARTS.
2475 * main.c (always_make_set): New variable. Change the -B option to
2476 set this one instead.
2477 (main): When checking makefiles, only set always_make_flag if
2478 always_make_set is set AND the restarts flag is 0. When building
2479 normal targets, set it IFF always_make_set is set.
2480 (main): Avoid infinite recursion with -W, too: only set what-if
2481 files to NEW before we check makefiles if we've never restarted
2482 before. If we have restarted, set what-if files to NEW _after_ we
2484 Fixes Savannah bug #7566:
2486 2005-06-17 Paul D. Smith <psmith@gnu.org>
2488 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2489 in the prerequisites list.
2491 2005-06-12 Paul D. Smith <psmith@gnu.org>
2493 Fix Savannah bug # 1328.
2495 * configure.in: Check for atexit().
2496 * misc.c (close_stdout): Test stdout to see if writes to it have
2497 failed. If so, be sure to exit with a non-0 error code. Based on
2498 code found in gnulib.
2499 * make.h: Prototype.
2500 * main.c (main): Install close_stdout() with atexit().
2502 2005-06-10 Paul D. Smith <psmith@gnu.org>
2504 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2506 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2507 headers; make vmsWaitForChildren() static; extern vmsify().
2508 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2509 Don't create child_execute_job() here (it's in vmsjobs.c).
2510 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2512 2005-06-09 Paul D. Smith <psmith@gnu.org>
2514 * variable.c (push_new_variable_scope): File variables point
2515 directly to the global_setlist variable. So, inserting a new
2516 scope in front of that has no effect on those variables: they
2517 don't go through current_variable_set_list. If we're pushing a
2518 scope and the current scope is global, push it "the other way" so
2519 that the new setlist is in the global_setlist variable, and
2520 next points to a new setlist with the global variable set.
2521 (pop_variable_scope): Properly undo a push with the new
2523 Fixes Savannah bug #11913.
2525 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2527 * job.c (reap_children): Don't die of the command failed but
2528 the dontcare flag is set. Fixes Savannah bug #13216.
2530 * implicit.c (pattern_search): When creating a target from
2531 an implicit rule match, lookup pattern target and set precious
2532 flag in a newly created target. Fixes Savannah bug #13218.
2534 2005-05-13 Paul D. Smith <psmith@gnu.org>
2536 Implement "if... else if... endif" syntax.
2538 * read.c (eval): Push all checks for conditional words ("ifeq",
2539 "else", etc.) down into the conditional_line() function.
2540 (conditional_line): Rework to allow "else if..." clause. New
2541 return value -2 for lines which are not conditionals. The
2542 ignoring flag can now also be 2, which means "already parsed a
2543 true branch". If that value is seen no other branch of this
2544 conditional can be considered true. In the else parsing if there
2545 is extra text after the else, invoke conditional_line()
2546 recursively to see if it's another conditional. If not, it's an
2547 error. If so, raise the conditional value to this level instead
2548 of creating a new conditional nesting level. Special check for
2549 "else" and "endif", which aren't allowed on the "else" line.
2550 * doc/make.texi (Conditional Syntax): Document the new syntax.
2552 2005-05-09 Paul D. Smith <psmith@gnu.org>
2554 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2555 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2556 recurses to the w32 directory, even on non-Windows systems. Use
2557 the method suggested in the automake manual.
2558 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2559 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2561 2005-05-07 Paul D. Smith <psmith@gnu.org>
2563 * main.c (die): If we're dying with a fatal error (not that a
2564 command has failed), write back any leftover tokens before we go.
2566 * job.c (set_child_handler_action_flags): If there are jobs
2567 waiting for the load to go down, set an alarm to go off in 1
2568 second. This allows us to wake up from a potentially long-lasting
2569 read() and start a new job if the load has gone down. Turn it off
2571 (job_noop): Dummy signal handler function.
2572 (new_job): Invoke it with the new semantics.
2574 * docs/make.texi: Document secondary expansion. Various cleanups
2577 2005-05-03 Paul D. Smith <psmith@gnu.org>
2579 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2580 the targets which are to ultimately be made are called "goals";
2581 see the GNU make manual. Also, MAKECMDGOALS, etc.
2583 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2584 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2585 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2587 2005-05-02 Paul D. Smith <psmith@gnu.org>
2589 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2590 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2591 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2592 functions to vmsjobs.c. #include it into jobs.c.
2594 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2595 jobserver tokens. I found that this happens when an exported
2596 recursive variable contains a $(shell ...) function reference: in
2597 this situation we could "forget" to write back a token.
2599 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2600 we have. It's not reliable to depend on the number of children in
2601 our linked list so keep a separate count.
2602 (new_job): Check jobserver_tokens rather than children &&
2603 waiting_jobs. Increment jobserver_tokens when we get one.
2604 (free_child): If jobserver_tokens is 0, internal error. If it's
2605 >1, write a token back to the jobserver pipe (we don't write a
2606 token for the "free" job). Decrement jobserver_tokens.
2608 * main.c: Add variable master_job_slots.
2609 (main): Set it to hold the number of jobs requested if we're the
2610 master process, when using the jobserver.
2611 (die): Sanity checks: first test jobserver_tokens to make sure
2612 this process isn't holding any tokens we didn't write back.
2613 Second, if master_job_slots is set count the tokens left in the
2614 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2616 2005-04-24 Paul D. Smith <psmith@gnu.org>
2618 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2619 with -l# can lose jobserver tokens, because waiting jobs are not
2620 consulted properly when checking for the "free" token.
2622 * job.c (free_child): Count waiting_jobs as having tokens.
2623 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2624 handle jobs waiting for the load to drop.
2626 2005-04-23 Paul D. Smith <psmith@gnu.org>
2628 * main.c (main): Be careful to not core if a variable setting in
2629 the environment doesn't contain an '='. This is illegal but can
2630 happen in broken setups.
2631 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2633 2005-04-12 Paul D. Smith <psmith@gnu.org>
2635 The second expansion feature causes significant slowdown. Timing
2636 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2637 read the makefile before the feature, to 11+s to do the same
2638 operations after the feature. Additionally, memory usage
2639 increased drastically. To fix this I added some intelligence that
2640 avoids the overhead of the second expansion unless it's required.
2642 * dep.h: Add a new boolean field, need_2nd_expansion.
2644 * read.c (eval): When creating the struct dep for the target,
2645 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2646 (record_files): If there's a "%" in a static pattern rule, it gets
2647 converted to "$*" so set need_2nd_expansion to 1.
2649 * file.c (expand_deps): Rework to be more efficient. Only perform
2650 initialize_file_variables(), set_file_variables(), and
2651 variable_expand_for_file() if the need_2nd_expansion is set.
2653 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2654 (pattern_search): Ditto.
2655 * main.c (handle_non_switch_argument): Ditto.
2657 * read.c (read_all_makefiles): Ditto.
2658 (eval_makefile): Ditto.
2660 2005-04-07 Paul D. Smith <psmith@gnu.org>
2662 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2663 * variable.c (sync_Path_environment): Ditto.
2664 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2666 * main.c (main): Define the .FEATURES variable.
2667 * NEWS: Announce .FEATURES.
2668 * doc/make.texi (Special Variables): Document .FEATURES.
2670 * remake.c (check_dep): If a file is .PHONY, update it even if
2671 it's marked intermediate. Fixes Savannah bug #12331.
2673 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2675 * file.c (expand_deps): Factor out the second expansion and
2676 prerequisite line parsing logic from snap_deps().
2678 * file.c (snap_deps): Use expand_deps(). Expand and parse
2679 prerequisites of the .SUFFIXES special target first. Fixes
2680 Savannah bug #12320.
2682 2005-03-13 Paul D. Smith <psmith@gnu.org>
2684 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2687 2005-03-11 Paul D. Smith <psmith@gnu.org>
2689 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2690 available, not undefined (from Earnie Boyd).
2692 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2694 * implicit.c (pattern_search): Mark an intermediate target as
2695 precious if it happened to be a prerequisite of some (other)
2696 target. Fixes Savannah bug #12267.
2698 2005-03-09 Paul D. Smith <psmith@gnu.org>
2700 * read.c (eval_makefile): Add alloca(0).
2701 (eval_buffer): Ditto.
2703 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2705 * main.c (main): Use o_file instead of o_default when defining
2706 the .DEFAULT_TARGET special variable.
2707 * read.c (eval): Use define_variable_global() instead of
2708 define_variable() when setting new value for the .DEFAULT_TARGET
2709 special variable. Fixes Savannah bug #12266.
2711 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2713 * imlicit.c (pattern_search): Mark files for which an implicit
2714 rule has been found as targets. Fixes Savannah bug #12202.
2716 2005-03-04 Paul D. Smith <psmith@gnu.org>
2719 * doc/make.texi (Automatic Variables): Document $|.
2721 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2723 * read.c (record_files): Instead of substituting % with
2724 actual stem value in dependency list replace it with $*.
2725 This fixes stem triple expansion bug.
2727 * implicit.c (pattern_search): Copy stem to a separate
2728 buffer and make it a properly terminated string. Assign
2729 this buffer instead of STEM (which is not terminated) to
2730 f->stem. Instead of substituting % with actual stem value
2731 in dependency list replace it with $*. This fixes stem
2732 triple expansion bug.
2734 2005-03-01 Paul D. Smith <psmith@gnu.org>
2736 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2737 on Windows, as it takes a handle not a pid. Just exit.
2738 Fix from patch #3679, provided by Alessandro Vesely.
2740 * configure.in: Update check for sys_siglist[] from autoconf manual.
2741 * signame.c (strsignal): Update to use the new autoconf macro.
2743 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2745 * read.c (record_files): Add a check for the list of prerequisites
2746 of a static pattern rule being empty. Fixes Savannah bug #12180.
2748 2005-02-28 Paul D. Smith <psmith@gnu.org>
2750 * doc/make.texi (Text Functions): Update docs to allow the end
2751 ordinal for $(wordlist ...) to be 0.
2752 * function.c (func_wordlist): Fail if the start ordinal for
2753 $(wordlist ...) is <1. Matches documentation.
2754 Resolves Savannah support request #103195.
2756 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2757 previously we were stopping when !-q, exactly the opposite. This
2758 has been wrong since version 1.34, in 1994!
2759 (update_file): If we got an error don't break out to run more
2760 double-colon rules: just return immediately.
2761 Fixes Savannah bug #7144.
2763 2005-02-27 Paul D. Smith <psmith@gnu.org>
2765 * misc.c (end_of_token): Make argument const.
2766 * make.h: Update prototype.
2768 * function.c (abspath, func_realpath, func_abspath): Use
2769 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2770 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2771 * read.c (record_files): Ditto.
2772 * variable.c (do_variable_definition): Ditto.
2774 * function.c (func_error): Create a new function $(info ...) that
2775 simply prints the message to stdout with no extras.
2776 (function_table_init): Add new function to the table.
2777 * NEWS: Add $(info ...) reference.
2778 * doc/make.texi (Make Control Functions): Document it.
2780 New feature: if the system supports symbolic links, and the user
2781 provides the -L/--check-symlink-time flag, then use the latest
2782 mtime between the symlink(s) and the target file.
2784 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2785 readlink(). If both are available, define MAKE_SYMLINKS.
2786 * main.c: New variable: check_symlink_flag.
2787 (usage): Add a line for -L/--check-symlink-times to the help string.
2788 (switches): Add -L/--check-symlink-times command line argument.
2789 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2790 print a warning and disable it again.
2791 * make.h: Declare check_symlink_flag.
2792 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2793 if the file is a symlink then check each link in the chain and
2794 choose the NEWEST mtime we find as the mtime for the file. The
2795 newest mtime might be the file itself!
2796 * NEWS: Add information about this new feature.
2797 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2799 Avoid core dumps described in Savannah bug # 12124:
2801 * file.c: New variable snapped_deps remember whether we've run
2803 (snap_deps): Set it.
2804 * filedef.h: Extern it.
2805 * read.c (record_files): Check snapped_deps; if it's set then
2806 we're trying to eval a new target/prerequisite relationship from
2807 within a command script, which we don't support. Fatal.
2809 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2811 Implementation of the .DEFAULT_TARGET special variable.
2813 * read.c (eval): If necessary, update default_target_name when
2815 * read.c (record_files): Update default_target_file if
2816 default_target_name has changed.
2817 * main.c (default_target_name): Define.
2818 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2819 default_target_name is set use default_target_file as a root
2821 * filedef.h (default_target_name): Declare.
2822 * dep.h (free_dep_chain):
2823 * misc.c (free_dep_chain): Change to operate on struct nameseq
2824 and change name to free_ns_chain.
2825 * file.c (snap_deps): Update to use free_ns_chain.
2827 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2829 Implementation of the second expansion in explicit rules,
2830 static pattern rules and implicit rules.
2832 * read.c (eval): Refrain from chopping up rule's dependencies.
2833 Store them in a struct dep as a single dependency line. Remove
2834 the code that implements SySV-style automatic variables.
2836 * read.c (record_files): Adjust the code that handles static
2837 pattern rules to expand all percents instead of only the first
2838 one. Reverse the order in which dependencies are stored so that
2839 when the second expansion reverses them again they appear in
2840 the makefile order (with some exceptions, see comments in
2841 the code). Remove the code that implements SySV-style automatic
2844 * file.c (snap_deps): Implement the second expansion and chopping
2845 of dependency lines for explicit rules.
2847 * implicit.c (struct idep): Define an auxiliary data type to hold
2848 implicit rule's dependencies after stem substitution and
2851 * implicit.c (free_idep_chain): Implement.
2853 * implicit.c (get_next_word): Implement helper function for
2854 parsing implicit rule's dependency lines into words taking
2855 into account variable expansion requests. Used in the stem
2858 * implicit.c (pattern_search): Implement the second expansion
2859 for implicit rules. Also fixes bug #12091.
2861 * commands.h (set_file_variables): Declare.
2862 * commands.c (set_file_variables): Remove static specifier.
2864 * dep.h (free_dep_chain): Declare.
2865 * misc.c (free_dep_chain): Implement.
2867 * variable.h (variable_expand_for_file): Declare.
2868 * expand.c (variable_expand_for_file): Remove static specifier.
2870 * make.h (strip_whitespace): Declare.
2871 * function.c (strip_whitespace): Remove static specifier.
2873 2005-02-26 Paul D. Smith <psmith@gnu.org>
2875 * main.c (main): Check for ferror() when reading makefiles from stdin.
2876 Apparently some shells in Windows don't close pipes properly and
2879 2005-02-24 Jonathan Grant <jg@jguk.org>
2881 * configure.in: Add MinGW configuration options, and extra w32 code
2883 * Makefile.am: Add MinGW configuration options, and extra w32 code
2885 * main.c: Determine correct program string (after last \ without .exe).
2886 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2888 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2889 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2890 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2891 environment support.
2893 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2895 * function.c (func_shell): When initializing error_prefix, check
2896 that reading file name is not null. This fixes long-standing
2897 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2899 2005-02-09 Paul D. Smith <psmith@gnu.org>
2901 * maintMakefile: Update the CVS download URL to simplify them.
2902 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2903 downloading the .texi files from Savannah now.
2905 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2907 * main.c (handle_non_switch_argument): Only add variables to
2908 command_variables if they're not already there: duplicate settings
2909 waste space and can be confusing to read.
2911 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2912 this header is never included by non-WINDOWS32 code, and it
2913 requires <config.h> to define which isn't always included first.
2915 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2916 testing MINGW32 versions.
2918 * main.c (log_working_directory): flush stdout to be sure the WD
2919 change is printed before any stderr messages show up.
2921 2005-02-01 Paul D. Smith <psmith@gnu.org>
2923 * maintMakefile (po_repo): Update the GNU translation site URL.
2925 2004-12-01 Paul D. Smith <psmith@gnu.org>
2927 * main.c (main): Change char* env_shell to struct variable shell_var.
2928 * variable.c (target_environment): Use new shell_var.
2930 2004-11-30 Paul D. Smith <psmith@gnu.org>
2932 * configure.in: The old way we avoided creating build.sh from
2933 build.sh.in before build.sh.in exists doesn't work anymore; we
2934 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2935 the help!). This also keeps automake from complaining.
2936 * Makefile.am (README): Add a dummy target so automake won't
2937 complain that this file doesn't exist when we checkout from CVS.
2938 * maintMakefile (.dep_segment): Rewrite this rule since newer
2939 versions of automake don't provide DEP_FILES.
2941 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2943 Implementation of `realpath' and `abspath' built-in functions.
2945 * configure.in: Check for realpath.
2946 * function.c (abspath): Return an absolute file name that does
2947 not contain any `.' or `..' components, nor repeated `/'.
2948 * function.c (func_abspath): For each name call abspath.
2949 * function.c (func_realpath): For each name call realpath
2950 from libc or delegate to abspath if realpath is not available.
2951 * doc/make.texi (Functions for File Names): Document new functions.
2952 * doc/make.texi (Quick Reference): Ditto.
2954 2004-11-28 Paul D. Smith <psmith@gnu.org>
2956 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2957 arguments. Fixes bug #10252.
2959 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2961 * main.c (main): Set SHELL to v_noexport by default. Remember the
2962 original environment setting of SHELL in the env_shell variable.
2963 * main.h: Export new env_shell variable.
2964 * variable.c (target_environment): If we find a v_noexport
2965 variable for SHELL, add a SHELL variable with the env_shell value.
2966 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2967 * doc/make.texi (Variables/Recursion): Ditto.
2969 2004-11-28 Paul D. Smith <psmith@gnu.org>
2971 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2972 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2973 Patch by Alessandro Vesely.
2975 2004-11-12 Paul D. Smith <psmith@gnu.org>
2977 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2978 the command line if it's inside a string.
2979 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2981 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2983 * function.c (func_lastword): New function: return last word
2984 from the list of words.
2985 * doc/make.texi: Document $(lastword ). Fix broken links in
2986 Quick Reference section.
2988 2004-10-06 Paul D. Smith <psmith@gnu.org>
2990 Apply patch from Alessandro Vesely, provided with bug # 9748.
2991 Fix use of tmpnam() to work with Borland C.
2993 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2994 construction of a temporary filename, and call new function
2995 create_batch_filename().
2996 (create_batch_filename) [WINDOWS32]: New function to create a
2999 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
3001 * read.c (record_target_var): Expand simple pattern-specific
3003 * variable.c (initialize_file_variables): Do not expand simple
3004 pattern-specific variable.
3006 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
3008 * remake.c (update_file_1): When rebuilding makefiles inherit
3009 dontcare flag from a target that triggered update.
3011 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
3013 * variable.c (initialize_file_variables): Mark pattern-specific
3014 variable as a per-target and copy export status.
3016 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
3018 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
3020 * implicit.c (pattern_search): When considering an implicit rule's
3021 prerequisite check that it is actually a target rather then
3022 just an entry in the file hashtable.
3024 2004-09-21 Paul D. Smith <psmith@gnu.org>
3026 * read.c (readstring): Fix some logic errors in backslash handling.
3027 (eval): Remove some unnecessary processing in buffer handling.
3028 (record_target_var): Assert that parse_variable_definition() succeeded.
3029 Reported by: Markus Mauhart <qwe123@chello.at>.
3031 * misc.c: Removed the sindex() function. All instances of this
3032 function were trivially replaceable by the standard strstr()
3033 function, and that function will always have better (or certainly
3034 no worse) performance than the very simple-minded algorithm
3035 sindex() used. This can matter with complex makefiles.
3036 * make.h: Remove the prototype for sindex().
3037 * function.c (subst_expand): Convert sindex() call to strstr().
3038 This means we no longer need to track the TLEN value so remove that.
3039 (func_findstring): Convert sindex() to strstr().
3040 * commands.c (chop_commands): Convert sindex() calls to strstr().
3041 Suggested by: Markus Mauhart <qwe123@chello.at>.
3043 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
3044 idea behind Savannah Patch #3144 from david.baird@homemail.com.
3045 If SHELL is set to CMD.EXE then assume it's batch-mode and
3046 non-unixy. I wrote the code differently from the patch, though,
3047 to make it safer. This also resolves bug #9174.
3049 2004-09-20 Paul D. Smith <psmith@gnu.org>
3051 * expand.c (variable_expand_string): Modify to invoke
3052 patsubst_expand() instead of subst_expand(); the latter didn't
3053 handle suffix patterns correctly.
3054 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
3055 was used only from variable_expand_string() and is no longer used
3057 (func_subst): Ditto, on call to subst_expand().
3058 (patsubst_expand): Require the percent pointers to point to the
3059 character after the %, not to the % itself.
3060 * read.c (record_files): New call criteria for patsubst_expand().
3061 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
3062 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
3064 2004-09-19 Paul D. Smith <psmith@gnu.org>
3066 * function.c (subst_expand): Fix a check in by_word: look for a
3067 previous blank if we're beyond the beginning of the string, not
3068 the beginning of the word.
3069 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3071 2004-05-16 Paul D. Smith <psmith@gnu.org>
3073 * remake.c (update_goal_chain): Change the argument specifying
3074 whether we're rebuilding makefiles to be a global variable,
3075 REBUILDING_MAKEFILES.
3076 (complain): Extract the code that complains about no rules to make
3077 a target into a separate function.
3078 (update_file_1): If we tried to rebuild a file during the makefile
3079 rebuild phase and it was dontcare, then no message was printed.
3080 If we then try to build the same file during the normal build,
3081 print a message this time.
3082 (remake_file): Don't complain about un-remake-able files when
3083 we're rebuilding makefiles.
3085 2004-05-11 Paul D. Smith <psmith@gnu.org>
3087 * job.c (construct_command_argv_internal): OS/2 patches from
3088 Andreas Buening <andreas.buening@nexgo.de>.
3090 2004-05-10 Paul D. Smith <psmith@gnu.org>
3092 * remake.c (update_file): Don't walk the double-colon chain unless
3093 this is a double-colon rule. Fix suggested by Boris Kolpackov
3094 <boris@kolpackov.net>.
3096 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3097 * readme.vms: New section describing OpenVMS support and issues.
3098 * default.c (default_variables): Add support for IA64.
3099 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3100 without some privilege aborts make with the error
3101 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3102 pressing Ctrl+Y and the input device is no terminal. The change
3103 catches this error and just continues.
3105 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3107 2004-04-25 Paul D. Smith <psmith@gnu.org>
3109 * commands.c (set_file_variables): Set $< properly in the face of
3110 order-only prerequisites.
3111 Patch from Boris Kolpackov <boris@kolpackov.net>
3113 2004-04-21 Bob Byrnes <byrnes@curl.com>
3115 * main.c (main): Notice failures to remake makefiles.
3117 2004-03-28 Paul D. Smith <psmith@gnu.org>
3119 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3121 * job.c: No default shell for RISC OS.
3122 (load_too_high): Hard-code the return to 1.
3123 (construct_command_argv_internal): No sh_chars or sh_cmds.
3124 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3126 2004-03-20 Paul D. Smith <psmith@gnu.org>
3128 * variable.c (do_variable_definition): Don't append from the
3129 global set if a previous non-appending target-specific variable
3130 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3133 * expand.c (reference_variable): Don't give up on variables with
3134 no value that have the target-specific append flag set: they might
3135 have a value after all. Reported by Oliver Schmidt
3136 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3137 <nikulin@dx1cmd.inp.nsk.su>.
3139 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3140 refer to absolute pathnames in directories that don't exist: some
3141 portion of the makefile could create those directories before we
3142 match the pattern. Fixes bugs #775 and #108.
3144 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3146 * main.c (main): Free makefile_mtimes if we have any.
3147 * README.W32.template: Update documentation for the current status
3148 of the MS-Windows port.
3149 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3150 environment variable is sometimes already defined which causes the
3152 * main.c (debug_signal_handler): Only define this function if
3153 SIGUSR1 is available.
3155 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3157 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3158 * README.OS2.template: Documentation updates.
3159 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3160 link line for safety.
3161 * maintMakefile (build.sh.in): Remove an extraneous ")".
3162 * job.c (child_execute_job): Close saved FDs.
3163 * job.c (exec_command) [OS/2]: exec_command(): If the command
3164 can't be exec'ed and if the shell is not Unix-sh, then try again
3165 with argv = { "cmd", "/c", ... }. Normally, this code is never
3166 reached for the cmd shell unless the command really doesn't exist.
3167 (construct_command_argv_internal) [OS/2]: The code for cmd
3168 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3169 The CMD builtin commands are case insensitive so use strcasecmp().
3171 2004-03-19 Paul D. Smith <psmith@gnu.org>
3173 * read.c (do_define): Re-order line counter increment so the count
3174 is accurate (we were losing one line per define). Reported by
3175 Dave Yost <Dave@Yost.com>.
3177 2004-03-06 Paul D. Smith <psmith@gnu.org>
3179 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3181 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3182 * misc.c (message,error,fatal): Ditto.
3183 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3184 * config.h.W32.template: Ditto.
3185 * config.h-vms.template: Ditto.
3186 * config.ami.template: Ditto.
3188 2004-03-04 Paul D. Smith <psmith@gnu.org>
3190 * README.template: Add a note about broken /bin/sh on SunOS
3191 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3193 * misc.c (message, error, fatal): Don't use "..." if we're using
3194 varargs. ansi2knr should handle this but it doesn't work: it
3195 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3196 done. On many systems (SunOS for example) va_dcl is a #define.
3197 So, force the use of the non-"..." version on pre-ANSI compilers.
3199 * maintMakefile (sign-dist): Create some rules to help automate
3200 the new GNU ftp upload method.
3202 2004-02-24 Paul D. Smith <psmith@gnu.org>
3204 * config.h.W32.template: Add HAVE_STDARG_H
3205 * config.h-vms.template: Ditto.
3206 * config.ami.template: Ditto.
3208 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3210 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3211 * build_w32.bat: Remove extra "+".
3213 2004-02-23 Paul D. Smith <psmith@gnu.org>
3215 * make.h: Create an UNUSED macro to mark unused parameters.
3216 * (many): Clean up warnings by applying UNUSED, fixing
3217 signed/unsigned incompatibilities, etc.
3219 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3221 * filedef.h: Name the command_state enumeration.
3222 * file.c (set_command_state): Use the enumeration in the function
3225 * configure.in: Explicitly set SET_MAKE to empty, to disable
3226 MAKE=make even when no make already exists. Fix bug #3823.
3228 2004-02-22 Paul D. Smith <psmith@gnu.org>
3230 * maintMakefile: Perl script to clean up all non-CVS files. Use
3231 it on all the subdirectories for the cvs-clean target.
3233 * main.c (decode_switches): Require non-empty strings for all our
3234 string command-line options. Fixes Debian bug # 164165.
3236 * configure.in: Check for stdarg.h and varargs.h.
3237 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3238 for printing messages.
3239 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3244 A number of patches for OS/2 support from Andreas Buening
3245 <andreas.buening@nexgo.de>:
3247 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3248 disable the SIGCHLD handler.
3249 (reap_children) [OS/2]: Remove special handling of job_rfd.
3250 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3251 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3252 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3253 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3254 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3257 2004-02-21 Paul D. Smith <psmith@gnu.org>
3259 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3260 <mail@kristov.de> reports that if process_begin() fails we don't
3261 handle the error condition correctly in all cases.
3262 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3263 to have a newline on the message.
3265 * job.c (construct_command_argv_internal): Add "test" to UNIX
3266 sh_cmds[]. Fixes Savannah bug # 7606.
3268 2004-02-04 Paul D. Smith <psmith@gnu.org>
3270 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3271 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3272 Hartmut Becker <Hartmut.Becker@hp.com>.
3274 2004-01-21 Paul D. Smith <psmith@gnu.org>
3276 * job.c (load_too_high): Implement an algorithm to control the
3277 "thundering herd" problem when using -l to control job creation
3278 via the load average. The system only recomputes the load once a
3279 second but we can start many jobs in a second. To solve this we
3280 keep track of the number of jobs started in the last second and
3281 apply a weight to try to guess what a correct load would be.
3282 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3283 Also fixes bug #4693.
3284 (reap_children): Decrease the job count for this second.
3285 (start_job_command): Increase the job count for this second.
3287 * read.c (conditional_line): Expand the text after ifn?def before
3288 checking to see if it's a single word. Fixes bug #7257.
3290 2004-01-09 Paul D. Smith <psmith@gnu.org>
3292 * file.c (print_file): Recurse to print all targets in
3293 double-colon rules. Fixes bug #4518, reported (with patch) by
3294 Andrew Chatham <chatham@google.com>.
3296 2004-01-07 Paul D. Smith <psmith@gnu.org>
3298 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3299 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3300 AC_FUNC_SETVBUF_REVERSED.
3302 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3303 (MAKE Variable): Fix Savannah bug #4898.
3305 * job.c (construct_command_argv_internal): Add "!" to the list of
3306 shell escape chars. POSIX sh allows it to appear before a
3307 command, to negate the exit code. Fixes bug #6404.
3309 * implicit.c (pattern_search): When matching an implicit rule,
3310 remember which dependencies have the ignore_mtime flag set.
3311 Original fix provided in Savannah patch #2349, by Benoit
3312 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3314 2003-11-22 Paul D. Smith <psmith@gnu.org>
3316 * README.W32.template (Outputs): Clarification on -j with
3317 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3320 2003-11-02 Paul D. Smith <psmith@gnu.org>
3322 * function.c (func_if): Strip all the trailing whitespace from the
3323 condition, then don't expand it. Fixed bug # 5798.
3325 * expand.c (recursively_expand_for_file): If we're expanding a
3326 variable with no file context, then use the variable's context.
3329 2003-10-21 Paul D. Smith <psmith@gnu.org>
3331 * main.c (log_working_directory): Add newlines to printf()s.
3333 * README.cvs: Add a note to ignore warnings during autoreconf.
3335 * maintMakefile (po_repo): Set a new URL for PO file updates.
3336 (get-config/config.guess get-config/config.sub): Get these files
3337 from the Savannah config project instead of ftp.gnu.org.
3339 2003-10-05 Paul Eggert <eggert@twinsun.com>
3341 * main.c (main): Avoid potential subscript error if environ has
3344 2003-08-22 Paul D. Smith <psmith@gnu.org>
3346 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3347 systems which don't yet implement the C89 standard :-/.
3349 2003-07-18 Paul D. Smith <psmith@gnu.org>
3351 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3352 [WINDOWS32]: Initialize hash.
3354 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3356 * dir.c (read_dirstream): Provide a workaround for broken versions of
3357 the MinGW dirent structure.
3359 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3361 * w32/include/dirent.h: Add __MINGW32__ filter.
3363 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3365 * make.h: Add global declaration of *make_host.
3366 * main.c (print_usage): Remove local declaration of *make_host.
3367 (print_version): Display "This program built for ..." after Copyright
3370 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3372 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3373 execution of "makeinfo --html make.texi".
3375 2003-04-30 Paul D. Smith <psmith@gnu.org>
3377 * build.template: Make some changes to maybe allow this script to
3378 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3380 * README.OS2.template: New file for OS/2 support. Original
3381 contributed by Andreas Buening.
3382 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3385 2003-04-19 Paul D. Smith <psmith@gnu.org>
3387 Fix bug #1405: allow a target to match multiple pattern-specific
3390 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3391 variable.c, where they've always belonged.
3392 * rule.h: Move the prototypes and struct pattern_var as well.
3393 * variable.c (initialize_file_variables): Invoke
3394 lookup_pattern_var() in a loop, until no more matches are found.
3395 If a match is found, create a new variable set for the target's
3396 pattern variables. Then merge the contents of each matching
3397 pattern variable set into the target's pattern variable set.
3398 (lookup_pattern_var): Change this function to be usable
3399 in a loop. It takes a starting position: if NULL, start at the
3400 beginning; if non-NULL, start with the pattern variable after that
3401 position, and return the next matching pattern.
3402 (create_pattern_var): Create a unique instance of
3403 pattern-specific variables for every definition in the makefile.
3404 Don't combine the same pattern together. This allows us to
3405 process the variable handling properly even when the same pattern
3406 is used multiple times.
3407 (parse_variable_definition): New function: break out the parsing
3408 of a variable definition line from try_variable_definition.
3409 (try_variable_definition): Call parse_variable_definition to
3411 (print_variable_data_base): Print out pattern-specific variables.
3412 * variable.h (struct variable): Remember when a variable is
3413 conditional. Also remember its flavor.
3414 (struct pattern_var): Instead of keeping a variable set, we just
3415 keep a single variable for each pattern.
3416 * read.c (record_target_var): Each pattern variable contains only a
3417 single variable, not a set, so create it properly.
3418 * doc/make.texi (Pattern-specific): Document the new behavior.
3420 2003-04-17 Paul D. Smith <psmith@gnu.org>
3422 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3423 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3424 file/directory naming rules for VMS so I can't tell whether this
3427 2003-04-09 Paul D. Smith <psmith@gnu.org>
3429 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3430 DOS-style pathnames: backslash separators and drive specifiers.
3432 2003-03-28 Paul D. Smith <psmith@gnu.org>
3434 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3435 the intermediate flag on all targets. Fixes bug #2515.
3437 2003-03-24 Paul D. Smith <psmith@gnu.org>
3439 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3440 Upgrade to autoconf 2.57 and automake 1.7.3.
3442 * job.c: More OS/2 changes from Andreas Buening.
3444 * file.c (print_file): Fix variable initialization.
3447 * remake.c (notice_finished_file):
3449 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3450 some calls (like readdir()) return NULL in valid situations
3451 without resetting errno. Fixes bug #2846.
3453 2003-02-25 Paul D. Smith <psmith@gnu.org>
3455 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3457 * job.c (_is_unixy_shell) [OS/2]: New function.
3458 Set default shell to /bin/sh.
3459 (reap_children): Close the job_rfd pipe here since we don't use a
3461 (set_child_handler_action_flags): define this to empty on OS/2.
3462 (start_job_command): Close the jobserver pipe and use
3463 child_execute_job() instead of fork/exec.
3464 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3465 rather than exec'ing, then reconfigure stdin/stdout.
3466 (exec_command): Rewrite to use spawn instead of exec. Return the
3469 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3470 in DOS. Handle the TEMP environment variable as in DOS. Don't
3471 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3472 use -j in DOS mode. Use child_execute_job() instead of
3475 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3478 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3479 prototypes that return values.
3481 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3483 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3484 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3486 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3489 2003-02-24 Paul D. Smith <psmith@gnu.org>
3491 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3492 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3493 (child_execute_job) [VMS]: Handle error status properly.
3494 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3496 * function.c (func_shell): Use EINTRLOOP() while reading from the
3497 subshell pipe (Fixes bug #2502).
3498 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3500 * main.c (main): Ditto.
3502 2003-01-30 Paul D. Smith <psmith@gnu.org>
3504 * read.c (eval): eval() was not fully reentrant, because the
3505 collapsed buffer was static. Change it to be an automatic
3506 variable so that eval() can be invoked recursively.
3508 (eval): Apply patch # 1022: fix memory reference error on long
3509 target-specific variable lines.
3510 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3512 * function.c (check_numeric): Combine the is_numeric() function
3513 into this function, since it's only called from one place.
3514 Constify this function. Have it print the incorrect string in the
3515 error message. Fixes bug #2407.
3516 (strip_whitespace): Constify.
3517 (func_if): Constify.
3518 * expand.c (expand_argument): Constify.
3520 2003-01-29 Paul D. Smith <psmith@gnu.org>
3522 Fix bug # 2169, also reported by other people on various systems.
3524 * make.h: Some systems, such as Solaris and PTX, do not fully
3525 implement POSIX-compliant SA_RESTART functionality; important
3526 system calls like stat() and readdir() can still fail with EINTR
3527 even if SA_RESTART has been set on the signal handler. So,
3528 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3529 EINTR for system calls which return -1 or 0 (NULL), respectively,
3531 Also, remove the old atomic_stat()/atomic_readdir() and
3532 HAVE_BROKEN_RESTART handling.
3534 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3536 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3537 * remake.c (touch_file): Ditto.
3539 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3540 * read.c (construct_include_path): Ditto.
3541 * remake.c (name_mtime): Ditto.
3542 * vpath.c (selective_vpath_search): Ditto.
3543 * dir.c (find_directory): Ditto.
3544 (local_stat): Ditto.
3545 (find_directory): Use ENULLLOOP() to wrap opendir().
3546 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3548 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3549 atomic_readdir() handling.
3551 2003-01-22 Paul D. Smith <psmith@gnu.org>
3553 * function.c (func_call): Fix Bug #1744. If we're inside a
3554 recursive invocation of $(call ...), mask any of the outer
3555 invocation's arguments that aren't used by this one, so that this
3556 invocation doesn't "inherit" them accidentally.
3558 2002-12-05 Paul D. Smith <psmith@gnu.org>
3560 * function.c (subst_expand): Valery Khamenia reported a
3561 pathological performance hit when doing substitutions on very
3562 large values with lots of words: turns out we were invoking
3563 strlen() a ridiculous number of times. Instead of having each
3564 call to sindex() call strlen() again, keep track of how much of
3565 the text we've seen and pass the length to sindex().
3567 2002-11-19 Paul D. Smith <psmith@gnu.org>
3569 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3572 2002-11-16 Paul D. Smith <psmith@gnu.org>
3574 * NMakefile.template (OBJS): Add hash.c object file.
3575 * SMakefile.template (srcs): Ditto.
3576 * Makefile.ami (objs): Ditto.
3577 * build_w32.bat: Ditto.
3579 * Makefile.DOS.template: Remove extra dependencies.
3581 2002-10-25 Paul D. Smith <psmith@gnu.org>
3583 * expand.c (install_variable_buffer): New function. Install a new
3584 variable_buffer context and return the previous one.
3585 (restore_variable_buffer): New function. Free the current
3586 variable_buffer context and put a previously saved one back.
3587 * variable.h: Prototypes for {install,restore}_variable_buffer.
3588 * function.c (func_eval): Push a new variable_buffer context
3589 before we eval, then restore the old one when we're done.
3592 * read.c (install_conditionals): New function. Install a new
3593 conditional context and return the previous one.
3594 (restore_conditionals): New function. Free the current
3595 conditional context and put a previously saved one back.
3596 (eval): Use the {install,restore}_conditionals for "include"
3598 (eval_buffer): Use {install,restore}_conditionals to preserve the
3599 present conditional state before we evaluate the buffer.
3602 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3604 (Recursion): Add a variable index entry for CURDIR.
3606 * README.cvs: Update to appropriate versions.
3607 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3608 don't need to copy loadavg.c: automake is smart enough to create
3609 it for me. Still have a bug in automake related to ansi2knr tho.
3611 2002-10-14 Paul D. Smith <psmith@gnu.org>
3613 * remake.c (notice_finished_file): Only touch targets if they have
3614 at least one command (as per POSIX). Resolve Bug #1418.
3616 * *.c: Convert to using ANSI C-style function definitions.
3617 * Makefile.am: Enable the ansi2knr feature of automake.
3618 * configure.in: ditto.
3620 2002-10-13 Paul D. Smith <psmith@gnu.org>
3622 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3623 for automatic variable values like $^, etc. In the case of very
3624 large lists of prerequisites this causes problems. Instead reuse
3625 a static buffer (resizeable) for each variable.
3627 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3628 target-specific variable definitions. Check for it and set an
3630 (record_target_var): Set the export field to v_export if the
3631 "exported" flag is set.
3632 * doc/make.texi (Target-specific): Document the ability to use
3635 * doc/make.texi: Change the name of the section on automatic
3636 variables from "Automatic" to "Automatic Variables". Added text
3637 clarifying the scope of automatic variables.
3639 2002-10-04 Paul D. Smith <psmith@gnu.org>
3641 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3643 (record_files): Ditto.
3645 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3646 the search for the '=' to only within the enclosing parens.
3648 2002-10-03 Paul D. Smith <psmith@gnu.org>
3650 Version 3.80 released.
3652 * dir.c: Change hash functions to use K&R function definition style.
3653 * function.c: Ditto.
3655 * variable.c: Ditto.
3657 Update to automake 1.7.
3659 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3660 (pdf): Remove this target as automake now provides one.
3662 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3664 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3666 * makefile.com: Updates for GNU make 3.80.
3667 * makefile.vms: Ditto.
3669 2002-09-23 Paul D. Smith <psmith@gnu.org>
3671 * read.c (enum make_word_type): Remove w_comment.
3672 (get_next_mword): Don't treat comment characters as special; where
3673 this function is used we will never see a comment (it's stripped
3674 before we get here) and treating comments specially means that
3675 targets like "foo\#bar" aren't handled properly.
3677 2002-09-18 Paul D. Smith <psmith@gnu.org>
3679 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3681 * read.c (eval): Expansion of arguments to export/unexport was
3682 ignoring all arguments after the first one. Change the algorithm
3683 to expand the whole line once, then parse the results.
3685 2002-09-17 Paul D. Smith <psmith@gnu.org>
3687 Fix Bug #940 (plus another bug I found while looking at this):
3689 * read.c (record_target_var): enter_file() will add a new entry if
3690 it's a double-colon target: we don't want to do that in this
3691 situation. Invoke lookup_file() and only enter_file() if it does
3692 not already exist. If the file we get back is a double-colon then
3693 add this variable to the "root" double-colon target.
3695 * variable.c (initialize_file_variables): If this file is a
3696 double-colon target but is not the "root" target, then initialize
3697 the root and make the root's variable list the parent of our
3700 2002-09-13 Paul D. Smith <psmith@gnu.org>
3702 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3704 * hash.c (round_up_2): Get rid of a warning.
3706 2002-09-12 Paul D. Smith <psmith@gnu.org>
3708 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3709 so it doesn't complain about getloadavg.c.
3711 * commands.c (set_file_variables): Make sure we always alloca() at
3712 least 1 character for the value of $? (for '\0').
3714 2002-09-11 Paul D. Smith <psmith@gnu.org>
3716 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3717 macro to use RESULT instead of the incorrect _RESULT_.
3719 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3720 and atomic_readdir(). We need to #include dirent.h to get this to
3722 * misc.c (atomic_readdir): Fix typos.
3724 2002-09-10 Paul D. Smith <psmith@gnu.org>
3726 * read.c (eval): Expand variable lists given to export and
3727 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3728 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3730 * doc/make.texi (Variables/Recursion): Document this.
3731 (Conditional Syntax): And here.
3733 2002-09-09 Paul D. Smith <psmith@gnu.org>
3735 * configure.in: Check for memmove().
3737 2002-09-07 Paul D. Smith <psmith@gnu.org>
3739 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3740 Michael Sterrett <msterret@coat.com> reports that while it has
3741 SA_RESTART, it does not work properly.
3743 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3744 that invokes stat() and loops to do it again if it returns EINTR.
3745 (atomic_readdir): Ditto, with readdir().
3747 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3748 and readdir() to atomic_stat() and atomic_readdir().
3750 2002-09-04 Paul D. Smith <psmith@gnu.org>
3752 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3753 reports that GNU make sometimes doesn't recognize that targets can
3754 be made, when directories can be created as prerequisites. He
3755 reports that changing the order of predicates in the DEP->changed
3756 flag test so that lookup_file() is always performed, solves this
3759 2002-08-08 Paul D. Smith <psmith@gnu.org>
3761 * configure.in: Require a newer version of gettext.
3763 * misc.c (perror_with_name): Translate the format string (for
3764 right-to-left language support).
3765 (pfatal_with_name): Ditto.
3767 * main.c: Create a static array of strings to store the usage
3768 text. This is done to facilitate translations.
3769 (struct command_switch): Remove argdesc and description fields.
3770 (switches): Remove values for obsolete fields.
3771 (print_usage): Print each element of the usage array.
3773 * hash.c: Change function definitions to be K&R style.
3775 2002-08-02 Paul D. Smith <psmith@gnu.org>
3777 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3778 this one because it's too hard to get right. We'll look at it for
3780 * main.c (main): Don't create the .TARGETS variable.
3781 * variable.c (handle_special_var): Don't handle .TARGETS.
3783 2002-08-01 Paul D. Smith <psmith@gnu.org>
3785 * main.c (switches): Add a new option, -B (--always-make). If
3786 specified, make will rebuild all targets that it encounters even
3787 if they don't appear to be out of date.
3788 (always_make_flag): New flag.
3789 * make.h: Extern always_make_flag.
3790 * remake.c (update_file_1): Check always_make_flag; if it's set we
3791 will always rebuild any target we can, even if none of its
3792 prerequisites are newer.
3795 * doc/make.texi (Shell Function): Make it clear that make
3796 variables marked as "export" are not passed to instances of the
3799 Add new introspection variable .VARIABLES and .TARGETS.
3801 * variable.c (handle_special_var): New function. If the variable
3802 reference passed in is "special" (.VARIABLES or .TARGETS),
3803 calculate the new value if necessary. .VARIABLES is handled here:
3804 walk through the hash of defined variables and construct a value
3805 which is a list of the names. .TARGETS is handled by
3806 build_target_list().
3807 (lookup_variable): Invoke handle_special_var().
3808 * file.c (build_target_list): Walk through the hask of known files
3809 and construct a list of the names of all the ones marked as
3811 * main.c (main): Initialize them to empty (and as simple variables).
3812 * doc/make.texi (Special Variables): Document them.
3813 * NEWS: Mention them.
3815 * variable.h (struct variable): Add a new flag "exportable" which
3816 is true if the variable name is valid for export.
3817 * variable.c (define_variable_in_set): Set "exportable" when a new
3818 variable is defined.
3819 (target_environment): Use the "exportable" flag instead of
3820 re-checking the name here... an efficiency improvement.
3822 2002-07-31 Paul D. Smith <psmith@gnu.org>
3824 * config.h-vms.template: Updates to build on VMS. Thanks to
3825 Brian_Benning@aksteel.com for helping verify the build.
3826 * makefile.com: Build the new hash.c file.
3827 * hash.h: Use strcpmi(), not stricmp(), in the
3828 HAVE_CASE_INSENSITIVE_FS case.
3830 2002-07-30 Paul D. Smith <psmith@gnu.org>
3832 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3833 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3834 Reported by <Brian_Benning@aksteel.com>.
3836 2002-07-10 Paul D. Smith <psmith@gnu.org>
3838 * variable.c (pop_variable_scope): Remove variable made unused by
3839 new hash infrastructure.
3840 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3841 comparisons as well as name comparisons.
3842 * variable.h: Add a prototype for new hash_init_function_table().
3843 * file.c (lookup_file): Remove variables made unused by new hash
3845 * dir.c (directory_contents_hash_2): Missing return of hash value.
3846 (dir_contents_file_exists_p): Remove variables made unused by new
3847 hash infrastructure.
3850 Installed Greg McGary's integration of the hash functions from the
3851 GNU id-utils package:
3853 2002-07-10 Greg McGary <greg@mcgary.org>
3855 * scripts/functions/filter-out: Add literals to to the
3856 pattern space in order to add complexity, and trigger
3857 use of an internal hash table. Fix documentation strings.
3858 * scripts/targets/INTERMEDIATE: Reverse order of files
3859 passed to expected `rm' command.
3861 2002-07-10 Greg McGary <greg@mcgary.org>

3953 2002-07-10 Paul D. Smith <psmith@gnu.org>
3955 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3956 prerequisite list. A real SysV make will expand the entire
3957 prerequisites list _twice_: we don't do that as it's a big
3958 backward-compatibility problem. We only replace those specific
3961 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3962 references left in the list of prerequisites. Check for .POSIX as
3963 we record targets, so we can disable non-POSIX behavior while
3964 reading makefiles as well as running them.
3965 (eval): Check the prerequisite list to see if we have anything
3966 that looks like a SysV prerequisite variable reference.
3968 2002-07-09 Paul D. Smith <psmith@gnu.org>
3970 * doc/make.texi (Prerequisite Types): Add a new section describing
3971 order-only prerequisites.
3973 * read.c (uniquize_deps): If we have the same file as both a
3974 normal and order-only prereq, get rid of the order-only prereq,
3975 since the normal one supersedes it.
3977 2002-07-08 Paul D. Smith <psmith@gnu.org>
3979 * AUTHORS: Added Greg McGary to the AUTHORS file.
3980 * NEWS: Blurbed order-only prerequisites.
3981 * file.c (print_file): Show order-only deps properly when printing
3984 * maintMakefile: Add "update" targets for wget'ing the latest
3985 versions of various external files. Taken from Makefile.maint in
3988 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3989 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3991 2002-07-07 Paul D. Smith <psmith@gnu.org>
3993 * po/*.po: Remove. We'll use wget to retrieve them at release
3996 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3997 rather than a shell you get an exception. Make sure we look up
3998 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
4000 * remake.c (notice_finished_file): Fix handling of -t flag.
4001 Patch provided by Henning Makholm <henning@makholm.net>.
4003 * implicit.c (pattern_search): Some systems apparently run short
4004 of stack space, and using alloca() in this function caused an
4005 overrun. I modified it to use xmalloc() on the two variables
4006 which seemed like they might get large. Fixes Bug #476.
4008 * main.c (print_version): Update copyright notice to conform with
4010 (print_usage): Update help output.
4012 * function.c (func_eval): Create a new make function, $(eval
4013 ...). Expand the arguments, put them into a buffer, then invoke
4014 eval_buffer() on the resulting string.
4015 (func_quote): Create a new function, $(quote VARNAME). Inserts
4016 the value of the variable VARNAME without expanding it any
4019 * read.c (struct ebuffer): Change the linebuffer structure to an
4020 "eval buffer", which can be either a file or a buffer.
4021 (eval_makefile): Move the code in the old read_makefile() which
4022 located a makefile into here: create a struct ebuffer with that
4023 information. Have it invoke the new function eval() with that
4025 (eval_buffer): Create a new function that creates a struct ebuffer
4026 that holds a string buffer instead of a file. Have it invoke
4027 eval() with that ebuffer.
4028 (eval): New function that contains the guts of the old
4029 read_makefile() function: this function parses makefiles. Obtains
4030 data to parse from the provided ebuffer. Some modifications to
4031 make the flow of the function cleaner and clearer. Still could
4032 use some work here...
4033 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
4034 contents of the define/endef variable from the ebuffer.
4035 (readstring): Read the next line from a string-style ebuffer.
4036 (readline): Read the next line from an ebuffer. If it's a string
4037 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
4040 * dep.h (eval_buffer): Prototype eval_buffer();
4042 * variable.c (do_variable_definition): Make sure that all
4043 non-target-specific variables are registered in the global set.
4044 If we're invoked from an $(eval ...) we might be inside a $(call
4045 ...) or other function which has pushed a variable scope; we still
4046 want to define our variables from evaluated makefile code in the
4049 2002-07-03 Greg McGary <greg@mcgary.org>
4051 * dep.h (struct dep) [ignore_mtime]: New member.
4052 [changed]: convert to a bitfield.
4053 * implicit.c (pattern_search): Zero ignore_mtime.
4054 * main.c (main, handle_non_switch_argument): Likewise.
4055 * rule.c (convert_suffix_rule): Likewise.
4056 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
4057 (read_makefile): Parse '|' in prerequisite list.
4058 (uniquize_deps): Consider ignore_mtime when comparing deps.
4059 * remake.c (update_file_1, check_dep): Don't force remake for
4060 dependencies that have d->ignore_mtime.
4061 * commands.c (FILE_LIST_SEPARATOR): New constant.
4062 (set_file_variables): Don't include a
4063 prerequisite in $+, $^ or $? if d->ignore_mtime.
4066 2002-06-18 Paul D. Smith <psmith@gnu.org>
4068 * make.texinfo: Updates for next revision. New date/rev/etc.
4069 Recreate all Info menus. Change license on the manual to the GNU
4070 Free Documentation License. A number of typos.
4071 (Variables Simplify): Don't use "-" before it's defined.
4072 (Automatic Prerequisites): Rewrite the target example to work
4073 properly if the compile fails. Remove incorrect comments about
4074 how "set -e" behaves.
4075 (Text Functions): Move the "word", "wordlist", "words", and
4076 "firstword" functions here, from "File Name Functions".
4077 * make-stds.texi: Update from latest GNU version.
4078 * fdl.texi: (created) Import the latest GNU version.
4080 2002-06-06 Paul D. Smith <psmith@gnu.org>
4082 * variable.c (do_variable_definition): New function: extract the
4083 part of try_variable_definition() that actually sets the value
4084 into a separate function.
4085 (try_variable_definition): Call do_variable_definition() after
4086 parsing the variable definition string.
4087 (define_variable_in_set): Make the name argument const.
4089 * variable.h (enum variable_flavor): Make public.
4090 (do_variable_definition): Create prototype.
4092 * read.c (read_all_makefiles): Create a new built-in variable,
4094 (read_makefile): Add each makefile read in to this variable value.
4096 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4098 * Makefile.DOS.template: Tweak according to changes in the
4099 distribution. Add back the dependencies of *.o files.
4101 * configh.dos.template: Synchronize with config.h.in.
4103 2002-05-09 Paul D. Smith <psmith@gnu.org>
4105 * file.c (file_timestamp_now): Use K&R function declaration.
4107 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4108 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4109 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4110 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4111 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4112 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4113 nlist.n_name is a pointer rather than an array.
4115 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4116 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4117 * configure.in: Use it instead of the old version.
4119 * main.c (main): Prefer setvbuf() to setlinebuf().
4121 2002-05-08 Paul D. Smith <psmith@gnu.org>
4123 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4124 (loadavg_LDADD): Ditto.
4126 2002-04-29 Paul D. Smith <psmith@gnu.org>
4128 * expand.c (recursively_expand_for_file): Rename
4129 recursively_expand() to recursively_expand_for_file() and provide
4130 an extra argument, struct file. If the argument is provided, set
4131 the variable scope to that of the file before expanding.
4132 * variable.h (recursively_expand): Make this a macro that invokes
4133 recursively_expand_for_file() with a NULL file pointer.
4134 * variable.c (target_environment): Call the renamed function and
4135 provide the current file context.
4136 Fixes Debian bug #144306.
4138 2002-04-28 Paul D. Smith <psmith@gnu.org>
4140 Allow $(call ...) user-defined variables to be self-referencing
4141 without throwing an error. Allows implementation of transitive
4142 closures, among other possibly useful things.
4143 Requested by: Philip Guenther <guenther@sendmail.com>
4145 * variable.h (struct variable): Add a new field: exp_count, and
4146 new macros to hold its size and maximum value.
4147 (warn_undefined): Make this a macro.
4148 * variable.c (define_variable_in_set): Initialize it.
4149 * expand.c (recursively_expand): If we detect recursive expansion
4150 of a variable, check the exp_count field. If it's greater than 0
4151 allow the recursion and decrement the count.
4152 (warn_undefined): Remove this (now a macro in variable.h).
4153 * function.c (func_call): Before we expand the user-defined
4154 function, modify its exp_count field to contain the maximum
4155 number of recursive calls we'll allow. After the call, reset it
4158 2002-04-21 Paul D. Smith <psmith@gnu.org>
4160 Modified to use latest autoconf (2.53), automake (1.6.1), and
4161 gettext (0.11.1). We're using gettext's new "external" support,
4162 to avoid including libintl source with GNU make.
4164 * README.cvs: New file. Explain how to build GNU make from CVS.
4166 * configure.in: Modify checking for the system glob library.
4167 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4168 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4169 etc. will manage it correctly). Set an automake conditional
4170 USE_LOCAL_GLOB to decide whether to compile the glob library.
4172 * getloadavg.c (main): Include make.h in the "TEST" program to
4175 * Makefile.am: Remove special rules for loadavg. Replace them
4176 with Automake capabilities for building extra programs.
4178 * signame.c: This file does nothing if the system provide
4179 strsignal(). If not, it implements strsignal(). If the system
4180 doesn't define sys_siglist, then we make our own; otherwise we use
4182 * signame.h: Removed.
4184 * main.c (main): No need to invoke signame_init(). Update copyright.
4186 * ABOUT-NLS: Removed.
4187 * gettext.c: Removed.
4188 * gettext.h: Get a simplified copy from the gettext package.
4190 * i18n/*.po: Moved to po/.
4193 * config/*: Created. Contains package configuration helper files.
4194 * config.guess, config.sub: Moved to config directory.
4196 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4197 Rework to use new-style autoconf features. Use the "external"
4198 mode for gettext. Make the build.sh config file conditional on
4199 whether build.sh.in exists, to avoid autoconf errors.
4200 * acinclude.m4: Removed almost all macros as being obsolete.
4201 Rewrote remaining macros to use AC_DEFINE.
4202 * acconfig.h: Removed.
4204 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4205 conditional to handle customs support. Remove special handling
4208 2002-04-20 Paul D. Smith <psmith@gnu.org>
4210 * function.c (func_call): Don't mark the argument variables $1,
4211 etc. as recursive. They've already been fully expanded so
4212 there's no need to do it again, and doing so strips escaped $'s.
4213 Reported by Sebastian Glita <glseba@yahoo.com>.
4215 * remake.c (notice_finished_file): Walk through double-colon
4216 entries via the prev field, not the next field!
4217 Reported by Greg McGary <greg@mcgary.org>.
4219 * main.c (main): If the user specifies -q and asks for a specific
4220 target which is a makefile, we got an assert. In that case it
4221 turns out we should continue normally instead.
4223 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4225 * i18n/he.po: Installed a new translation.
4227 2002-01-07 Paul D. Smith <psmith@gnu.org>
4229 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4231 2001-12-04 Paul D. Smith <psmith@gnu.org>
4233 * i18n/ja.po: Installed an updated translation.
4235 2001-09-06 Paul Eggert <eggert@twinsun.com>
4237 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4238 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4240 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4242 (main): Get rid of any avoidable limit on stack size.
4244 2001-09-04 Paul D. Smith <psmith@gnu.org>
4246 * i18n/da.po: Installed an updated translation.
4248 2001-08-03 Paul D. Smith <psmith@gnu.org>
4250 * i18n/fr.po: Installed an updated translation.
4251 Resolves Debian bug #106720.
4253 2001-06-13 Paul D. Smith <psmith@gnu.org>
4255 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4258 2001-06-11 Paul D. Smith <psmith@gnu.org>
4260 * i18n/ko.po: Installed a new translation.
4262 2001-05-06 Paul D. Smith <psmith@gnu.org>
4264 Modify the EINTR handling.
4266 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4267 the way in which we manage the file descriptor/signal handler race
4268 trap to be more efficient.
4270 2001-05-06 Paul Eggert <eggert@twinsun.com>
4272 Restart almost all system calls that are interrupted, instead
4273 of worrying about EINTR. The lone exception is the read() for
4276 * configure.in (HAVE_SA_RESTART): New macro.
4277 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4278 * main.c (main): Use SA_RESTART instead of the old,
4279 nonstandard SA_INTERRUPT.
4281 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4282 * main.c (bsd_signal): New function or macro,
4283 if the implementation doesn't supply it.
4284 (The bsd_signal function will be in POSIX 1003.1-200x.)
4285 (HANDLESIG): Remove.
4286 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4288 * make.h (EINTR_SET): Remove.
4289 (SA_RESTART): New macro.
4291 * arscan.c (ar_member_touch): Don't worry about EINTR.
4292 * function.c (func_shell): Likewise.
4293 * job.c (reap_children, free_child, new_job): Likewise.
4294 * main.c (main): Likewise.
4295 * remake.c (touch_file, name_mtime): Likewise.
4297 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4298 if fstat failed with errno!=EINTR, the error was ignored.
4300 * job.c (set_child_handler_action_flags): New function.
4301 (new_job): Use it to temporarily clear the SIGCHLD action flags
4302 while reading the token.
4304 2001-05-02 Paul D. Smith <psmith@gnu.org>
4306 * job.c (start_job_command): Don't add define/endef per-line flags
4307 to the top-level flags setting.
4309 2001-04-03 Paul D. Smith <psmith@gnu.org>
4311 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4312 bit on error, so check for odd return values, not non-0 return
4314 (VMS_get_member_info): Calculate the timezone differences correctly.
4315 Reported by John Fowler <jfowler@nyx.net>.
4318 2001-03-14 Paul D. Smith <psmith@gnu.org>
4320 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4321 value before invoking define_variable().
4322 Reported by John Fowler <jfowler@nyx.net>.
4324 2001-02-07 Paul D. Smith <psmith@gnu.org>
4326 * read.c (record_target_var): If we reset the variable due to a
4327 command-line variable setting overriding it, turn off the "append"
4330 2001-01-17 Paul D. Smith <psmith@gnu.org>
4332 * variable.c (lookup_variable) [VMS]: When getting values from the
4333 environment, allocate enough space for the _value_ plus escapes,
4334 not enough space for the name plus escapes :-/.
4335 Reported by John Fowler <jfowler@nyx.net>.
4337 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4338 warnings that make generates, so it doesn't look like an error.
4339 Reported by Karl Berry <karl@gnu.org>.
4342 Fix for PR/2020: Rework appended target-specific variables. I'm
4343 fairly confident this algorithm is finally correct.
4345 * expand.c (allocated_variable_append): Rewrite. Instead of
4346 expanding each appended variable then adding all the expanded
4347 strings together, we append all the unexpanded values going up
4348 through the variable set contexts, then expand the final result.
4349 This behaves just like non-target-specific appended variable
4350 values, while the old way didn't in various corner cases.
4351 (variable_append): New function: recursively append the unexpanded
4352 value of a variable, walking from the outermost variable scope to
4354 * variable.c (lookup_variable): Remove the code that looked up the
4355 variable set list if the found variable was "append". We don't
4357 (lookup_variable_in_set): Make this non-static so we can use it
4359 (try_variable_definition): Use lookup_variable_in_set() rather
4360 than faking out current_variable_set_list by hand (cleanup).
4361 * variable.h: Add a prototype for the now non-static
4362 lookup_variable_in_set().
4364 2000-11-17 Paul D. Smith <psmith@gnu.org>
4366 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4367 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4368 before throwing a fit.
4370 2000-11-17 Paul D. Smith <psmith@gnu.org>
4372 * read.c (readline): CRLF calculations had a hole, if you hit the
4373 buffer grow scenario just right. Reworked the algorithm to avoid
4374 the need for len or lastlen at all. Problem description with
4375 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4377 2000-10-24 Paul D. Smith <psmith@gnu.org>
4379 * gettext.c (SWAP): Declare this with the prototype, otherwise
4380 some systems don't work (non-32-bit? Reported for Cray T3E).
4381 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4383 2000-10-05 Paul D. Smith <psmith@gnu.org>
4385 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4386 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4388 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4390 2000-09-22 Paul D. Smith <psmith@gnu.org>
4392 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4393 parts of the real gettext.h here, and we expect to really include
4394 the real gettext.h later. If we keep this #define, it's ignored.
4396 2000-09-21 Paul D. Smith <psmith@gnu.org>
4398 * main.c (log_working_directory): Rework the text to use complete
4399 sentences, to make life simpler for the translators.
4401 2000-08-29 Paul D. Smith <psmith@gnu.org>
4403 * file.c (remove_intermediates): Print a debug message before we
4404 remove intermediate files, so the user (if she uses -d) knows
4407 2000-08-21 Paul D. Smith <psmith@gnu.org>
4409 * variable.c (try_variable_definition): Change how we handle
4410 target-specific append variable defns: instead of just setting the
4411 value, expand it as an append _but_ only within the current
4412 target's context. Otherwise we lose all but the last value if the
4413 variable is appended more than once within the current target
4414 context. Fixes PR/1831.
4416 2000-08-16 Paul D. Smith <psmith@gnu.org>
4418 * function.c (func_shell): Nul-terminate the buffer before
4419 printing an exec error message (just in case it's not!).
4420 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4422 2000-07-25 Paul D. Smith <psmith@gnu.org>
4424 * job.c (construct_command_argv_internal): Add "~" to the list of
4425 sh_chars[] which disallow optimizing out the shell call.
4427 2000-07-23 Paul Eggert <eggert@twinsun.com>
4429 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4430 supersedes --disable-nsec-timestamps.
4431 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4432 * README: Remove --disable-nsec-timestamps.
4434 * filedef.h (struct file.low_resolution_time): New member.
4435 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4436 * remake.c (update_file_1):
4437 Avoid spurious rebuilds due to low resolution time stamps,
4438 generalizing the earlier code that applied only to archive members.
4439 (f_mtime): Archive members always have low resolution time stamps.
4441 * configure.in: Remove --disable-nsec-timestamps, as this has
4442 been superseded by .LOW_RESOLUTION_TIME.
4444 2000-07-23 Paul Eggert <eggert@twinsun.com>
4446 * configure.in (enable_nsec_timestamps): Renamed from
4447 make_cv_nsec_timestamps, since enable/disable options
4448 shouldn't be cached.
4450 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4451 and Paul Eggert <eggert@twinsun.com>
4453 * file.c (file_timestamp_now):
4454 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4455 so that clock_gettime is not linked unless needed.
4457 * filedef.h (FILE_TIMESTAMP_HI_RES):
4458 Remove definition; "configure" now does this.
4460 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4461 to before high resolution file timestamp check,
4462 since that check now uses uintmax_t.
4463 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4464 high resolution file timestamps.
4465 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4466 so that we don't link in clock_gettime unnecessarily.
4468 2000-07-17 Paul D. Smith <psmith@gnu.org>
4470 * i18n/ja.po: New version of the translation file.
4472 2000-07-07 Paul D. Smith <psmith@gnu.org>
4474 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4475 the offset calculation.
4476 (name_mtime): Replace EINTR test with EINTR_SET macro.
4478 2000-07-07 Paul Eggert <eggert@twinsun.com>
4482 * remake.c (update_file_1):
4483 Avoid spurious rebuilds of archive members due to their
4484 timestamp resolution being only one second.
4485 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4486 the clock's resolution being lower than file timestamps'.
4487 When warning about future timestamps, report only the discrepancy,
4488 not the absolute value of the timestamp and the current time.
4490 * file.c (file_timestamp_now): New arg RESOLUTION.
4491 * filedef.h (file_timestamp_now): Likewise.
4492 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4494 2000-07-05 Paul D. Smith <psmith@gnu.org>
4496 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4497 to listp. Fixes PR/1793.
4499 2000-06-26 Paul Eggert <eggert@twinsun.com>
4501 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4503 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4505 * remake.c (f_mtime): Remove unused var memtime.
4507 2000-06-25 Martin Buchholz <martin@xemacs.org>
4509 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4510 Ran spell-check on make.texinfo.
4512 2000-06-23 Paul D. Smith <psmith@gnu.org>
4514 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4515 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4516 * make.h: Define these macros.
4518 * Version 3.79.1 released.
4520 * configure.in: Add a new option, --disable-nsec-timestamps, to
4521 avoid using sub-second timestamps on systems that support it. It
4522 can lead to problems, e.g. if your makefile relies on "cp -p".
4523 * README.template: Document the issue with "cp -p".
4525 * config.guess, config.sub: Updated.
