3 * job.c (construct_command_argv_internal): Remove " from
4 sh_chars_dos[]. Ignore an escaped backslash inside a string
5 quoted with "..". This lifts the 4KB or 8KB command-line length
6 limitation imposed by the Windows shell when a command uses quoted
7 strings, because we now don't call the shell in that case.
9 * job.c (create_batch_file): Declare the counter of batch files
10 static, to avoid having 2 jobs using the same file name and
11 stepping on each other's toes. When all 64K names are used up,

13 avoids leaving behind temporary batch files in the temporary
14 directory, which happens frequently on a fast machine when using

717 * read.c (parse_file_seq): All archive groups must end with ')' as
718 the LAST character in a word. If there is no word ending in ')'

721 2010-07-01 Paul Smith <psmith@gnu.org>
723 * main.c (main): Append optional features using separate calls.

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

785 lowest directory index.
787 * implicit.c (pattern_search): Pass NULL for the index arguments in
788 the VPATH_SEARCH call.
790 * doc/make.texi (Directory Search for Link Libraries): Describe the
793 * NEWS: Add a note about the new behavior.

803 2009-10-24 Paul Smith <psmith@gnu.org>
805 * main.c (usage): Add --eval to the usage string.
806 (switches): Add the --eval switch.

849 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
851 * commands.c (set_file_variables): Avoid modifying the dep
852 chain to achieve uniqueness. Fixes savannah bug 25780.
854 * implicit.c (pattern_search): Instead of re-setting all automatic

877 * implicit.c (pattern_search): Initialize file variables only
878 if we need to parse a rule that requires the second expansion.
880 2009-10-03 Paul Smith <psmith@gnu.org>
882 * make.h: Include <alloca.h> even on systems where __GNUC__ is
883 defined. Not sure why it was done the other way.
884 Requested by David Boyce <dsb@boyski.com>.
886 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
888 * dep.h (dep): Add the DONTCARE bitfield.
890 * filedef.h (file):Add the NO_DIAG bitfield.
892 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
893 not struct file (a file can be a dependency of many targets,
894 some don't care, some do).
896 * remake.c (update_goal_chain): Propagate DONTCARE from struct
897 dep to struct file before updating the goal and restore it
899 (update_file): Don't prune the dependency graph if this target

902 that caused the failure.
903 (update_file_1): Use NO_DIAG instead of DONTCARE to decide
904 whether to print diagnostics.
906 Fixes Savannah bugs #15110, #25493, #12686, and #17740.

942 double-colons have a different meaning. Savannah bug #27497.
944 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
946 * configh.dos.template: Remove unconditional definition of
947 SYS_SIGLIST_DECLARED.
948 Include <sys/version.h> because ports of GCC 4.3.0 and later no
949 longer include it, so macros like __DJGPP_MINOR__ are no longer
950 defined automatically.
952 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
953 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
954 instead of using the hardcoded ones.
955 (SUBDIRS): doc subdir added.
956 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
957 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
958 create html formated docs. texi2html may not be ported to DOS.
959 (make.info, make.dvi, make.ps, make.html): Make targets depend on
961 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
962 -I switch to look in ./ instead of ./doc.
963 (html): Target depend on html-recursive instead of make_1.html.
964 (make_1.html): Removed.
965 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
966 (all-recursive): Allow for more than one subdir in the build
968 (mostlyclean-recursive, clean-recursive, distclean-recursive)
969 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
970 (tags-recursive): Allow for more than one subdir in the build
972 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
973 targets. Enter into doc/ to produce the targets.
974 (all-am): $(INFO_DEPS) replaced by info.
976 2009-09-26 Paul Smith <psmith@gnu.org>
978 * read.c (record_files): Use free_ns() to free struct nameseq.
981 * rule.c (freerule): Use free_dep_chain().
983 * read.c (record_files): Free FILENAMES chain for implicit rules.
984 (eval): Static pattern targets go into the string cache.
986 * function.c (string_glob): Free NAME in the nameseq chain.
988 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
990 * implicit.c (pattern_search): Terminate early if we haven't
991 found any rules to try (performance improvement).
993 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
995 * implicit.c (pattern_search): Merge three parallel arrays,
996 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
997 of struct TRYRULE. In the old version the latter two arrays
998 had insufficient length.
1000 2009-09-24 Paul Smith <psmith@gnu.org>
1002 * implicit.c (pattern_search): Add back support for order-only
1003 prerequisites for secondary expansion implicit rules, that were
1004 accidentally dropped. If we find a "|", enable order-only mode
1005 and set IGNORE_MTIME on all deps that are seen afterward.
1006 (pattern_search): Fix memory leaks: for intermediate files where
1007 we've already set the file variable and pattern variable sets, be
1008 sure to either save or free them as appropriate.
1010 2009-09-23 Paul Smith <psmith@gnu.org>
1012 Rework the way secondary expansion is stored, for efficiency.
1013 This changes secondary expansion so that ONLY WHEN we know we have
1014 a possibility of needing secondary expansion, do we defer the
1015 secondary expansion. This means more parsing the deps but we use
1016 a lot less memory (due to the strcache). Also, this fixes
1017 Savannah bug #18622.
1019 * read.c (eval): Don't parse the dep string here anymore.
1020 (record_files): Take the dep argument as an unparsed string. If
1021 secondary expansion is enabled AND the prereq string has a '$' in
1022 it, then set NEED_2ND_EXPANSION and keep the entire string.
1023 Otherwise, parse the dep string here to construct the dep list
1024 with the names in the strcache.
1026 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
1027 duplicate the name string (others are in the strcache).
1029 * implicit.c: Remove struct idep and free_idep_chain(): unused.
1030 (struct patdeps): New structure to store prereq information.
1031 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
1032 which prerequisites need expansion, and expand only those.
1034 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
1035 and enter_prereqs(). split_prereqs() takes a fully-expanded string
1036 and splits it into a DEP list, handling order-only prereqs.
1037 (enter_prereqs): This function enters a list of DEPs into the file
1038 database. If there's a stem defined, expand any pattern chars.
1039 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
1040 set. Use the above functions.
1041 (snap_deps): Only perform second expansion on prereqs that need it,
1042 as defined by the NEED_2ND_EXPANSION flag.
1043 (print_prereqs): New function to print the prereqs
1044 (print_file): Call print_prereqs() rather than print inline.
1046 * hash.h (STRING_COMPARE): Take advantage of strcache() by
1048 (STRING_N_COMPARE): Ditto.
1049 (ISTRING_COMPARE): Ditto.
1051 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
1052 (parse_file_seq): Return void*
1053 * read.c (parse_file_seq): Return void*.
1054 (eval): Invoke macroized version of parse_file_seq()
1055 * default.c (set_default_suffixes): Ditto.
1056 * file.c (split_prereqs): Ditto.
1057 * function.c (string_glob): Ditto.
1058 * main.c (main): Ditto.
1059 * rule.c (install_pattern_rule): Ditto.
1061 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
1063 2009-09-16 Paul Smith <psmith@gnu.org>
1065 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
1067 * dep.h: Create alloc_dep() / free_dep() macros.
1069 * implicit.c (pattern_search): Take advantage of the new
1070 parse_file_seq() to add the directory prefix to each prereq.
1072 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
1073 all. Avoid reversing chains. Support adding prefixes.
1074 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
1075 cached/non-cached results.
1076 (eval): Remove multi_glob() & invoke new parse_file_seq().
1077 * rule.c (install_pattern_rule): Ditto.
1078 * main.c (main): Ditto.
1079 * implicit.c (pattern_search): Ditto.
1080 * function.c (string_glob): Ditto.
1081 * file.c (parse_prereqs): Ditto.
1082 * default.c (set_default_suffixes): Ditto.
1084 * variable.c (parse_variable_definition): Don't run off the end of
1085 the string if it ends in whitespace (found with valgrind).
1087 * commands.c (set_file_variables): Keep space for all targets in
1088 $? if -B is given (found with valgrind).
1090 2009-09-15 Paul Smith <psmith@gnu.org>
1092 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
1093 (xcalloc): Add new function.
1094 * make.h: New declarations.
1096 * ar.c (ar_glob_match): New calling method for concat().
1097 * main.c (main): Ditto.

1102 * variable.c (target_environment): Ditto.
1103 (sync_Path_environment): Ditto.
1105 * ar.c (ar_glob_match): Use xcalloc().
1106 * dir.c (file_impossible): Ditto.
1107 * file.c (enter_file): Ditto.
1108 * job.c (new_job): Ditto.
1109 * read.c (parse_file_seq): Ditto.
1110 * vmsfunctions.c (opendir): Ditto.
1112 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
1114 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
1115 inside the loop that looks up environment for PATH.
1117 2009-08-31 Eli Zaretskii <eliz@gnu.org>
1119 * function.c (windows32_openpipe): Update envp after calling
1120 sync_Path_environment.
1122 2009-08-02 Paul Smith <psmith@gnu.org>
1124 * remake.c (notice_finished_file): Ensure file->cmds is not null
1125 before looping through them. Fixes Savannah bug #21824.
1127 * doc/make.texi (Wildcard Examples): Clarify when objects is
1128 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1129 (Include): Clarify the behavior of -include.
1130 Fixes Savannah bug #18963.
1132 2009-08-01 Paul Smith <psmith@gnu.org>
1134 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1135 etc. come on the command line. Fixes Savannah bug #27093.
1137 * expand.c (expand_argument): If the argument is large enough use
1138 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1140 * variable.c (do_variable_definition): Avoid using alloca() to
1141 hold values, which can be large. Fixes Savannah bug #23960.
1143 * job.c (new_job): Use memmove() instead of strcpy() since both
1144 pointers are in the same memory block. Fixes Savannah bug #27148.
1145 Patch by Petr Machata.
1147 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1149 * job.c (construct_command_argv_internal): Add "ulimit" and
1150 "unset" to the sh_cmds for Unixy shells.
1152 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1154 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1155 that set make_cv_sys_gnu_glob, so they are also correctly set
1156 when the cache has been populated before.
1158 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1160 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1161 exist, as realpath(3) does where it's supported.
1163 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1165 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1166 (abspath): Support systems that define HAVE_DOS_PATHS (have
1167 drive letters in their file names). Use IS_PATHSEP instead of a
1168 literal '/' comparison. Fixes Savannah bug #26886.
1170 2009-06-14 Paul Smith <psmith@gnu.org>
1172 * remake.c (update_file_1): Remember the original file we marked
1173 as updating, so we can clear that flag again. If we find a target
1174 via vpath, FILE might change.
1175 (check_dep): Ditto. Fixes Savannah bug #13529.
1176 Patch by Reid Madsen <reid.madsen@tek.com>.
1178 2009-06-13 Paul Smith <psmith@gnu.org>
1180 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1181 included by MAKEFILES cannot give default goals.
1182 * read.c (eval): If set_default is not set, pass the no-default-goal
1183 value when we read included makefiles. Fixes Savannah bug #13401.
1185 * ar.c (ar_name): Ensure that targets with empty parens aren't
1186 considered archive member references: archive members must have a
1187 non-empty "member" string. Fixes Savannah bug #18435.
1189 * function.c (string_glob): Rely on multi_glob() to determine
1190 whether files exist or not. Remove call to file_exists_p() which
1191 is not always correct. Fixes Savannah bug #21231.
1192 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1193 then only files that really exist will be returned.
1194 * dep.h: Add new argument to multi_glob().
1195 * rule.c (install_pattern_rule): Ditto.
1196 * read.c (eval): Ditto.
1197 * main.c (main): Ditto.
1198 * implicit.c (pattern_search): Ditto.
1199 * file.c (parse_prereqs): Ditto.
1200 * default.c (set_default_suffixes): Ditto.
1202 2009-06-09 Paul Smith <psmith@gnu.org>
1204 * commands.c (set_file_variables): If always_make_flag is set,
1205 always add the prereq to $?. Fixes Savannah bug #17825.
1207 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1208 to rebuild the deps of all the also_make targets for that file.
1209 Fixes Savannah bug #19108.
1211 * implicit.c (pattern_search): Undo test for is_target, added by
1212 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1213 Rule Search Algorithm". Fixes Savannah bug #17752.
1215 * main.c (clean_jobserver): Clear the jobserver_fds options and
1216 set job_slots to the default when we clean up.
1217 (define_makeflags): Return the new MAKEFLAGS value.
1218 (main): Reset MAKEFLAGS in the environment when we re-exec.
1219 Fixes Savannah bug #18124.
1221 2009-06-08 Paul Smith <psmith@gnu.org>
1223 * read.c (eval): Collapse continuations post-semicolon on target-
1224 specific variables. Fixes Savannah bug #17521.
1226 2009-06-07 Paul Smith <psmith@gnu.org>
1228 * job.c (reap_children): For older systems without waitpid() (are
1229 there any of these left?) run wait(2) inside EINTRLOOP to handle
1230 EINTR errors. Fixes Savannah bug #16401.
1232 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1234 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1236 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1237 not the end, to catch second expansion $(eval ...) defining new
1238 target/prereq relationships during snap_deps.
1239 Fixes Savannah bug #24622.
1241 * read.c (record_files): The second-expansion "f->updating" hack
1242 was not completely correct: if assumed that the target with
1243 commands always had prerequisites; if one didn't then the ordering
1244 was messed up. Fixed for now to use f->updating to decide whether
1245 to preserve the last element in the deps list... but this whole
1246 area of constructing and reversing the deps list is too confusing
1247 and needs to be reworked. Fixes Savannah bug #21198.
1249 2009-06-06 Paul Smith <psmith@gnu.org>
1251 * hash.c (hash_insert): Remove useless test for NULL.
1252 Fixes Savannah bug #21823.
1254 * make.h: Move SET_STACK_SIZE determination to make.h.
1255 * main.c (main): New global variable, STACK_LIMIT, holds the
1256 original stack limit when make was started.
1257 * job.c (start_job_command): Reset the stack limit, if we changed it.
1258 Fixes Savannah bug #22010.
1260 * remake.c (check_dep): Only set the target's state to not-started
1261 if it's not already running. Found this while testing -j10 builds
1262 of glibc: various targets were being rebuilt multiple times.
1263 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1266 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1267 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1270 2009-06-04 Paul Smith <psmith@gnu.org>
1272 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1274 * maintMakefile: Modify access of config and gnulib Savannah
1275 modules to use GIT instead of CVS.
1277 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1278 Fixes Savannah bug #24655.
1280 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1281 this can happen during some invocations of $(eval ...) for example.
1282 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1284 2009-06-02 Paul Smith <psmith@gnu.org>
1286 * configure.in: Check for fileno()
1287 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1288 for the makefile file so invocations of $(shell ...) don't inherit it.
1289 Fixes Savannah bug #24277.
1291 2009-06-01 Paul Smith <psmith@gnu.org>
1293 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1294 expansion was handled incorrectly. Rework the default goal
1295 handling to save the variable only. Remove default_goal_file and
1297 * read.c (eval): Check default_goal_var, not default_goal_name.
1298 * read.c (record_target_var): Don't check default_goal_file here.
1300 2009-05-31 Paul Smith <psmith@gnu.org>
1302 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1303 it, and if the multi_glob() returns nothing (say it expanded to
1304 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1306 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1307 $(and ..) to the reference. Fixes Savannah bug #25694.
1309 * make.1: Be clear that some recipes will be executed even with -n.
1310 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1312 * doc/make.texi (Override Directive): Make more clear how
1313 overrides and appends interact.
1314 Elucidates part of Savannah bug #26207.
1316 * read.c (record_target_var): Don't reset the origin on
1317 target-specific variables; try_variable_definition() will handle
1318 this correctly. Fixes Savannah bug #26207.
1320 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1321 Fixes Savannah bug #25712.
1323 * implicit.c (pattern_search): Keep a pointer to the beginning of
1324 the filename and save that instead of the constructed pointer.
1325 Fixes Savannah bug #26593.
1326 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1328 2009-05-30 Paul Smith <psmith@gnu.org>
1330 * doc/make.texi (Multi-Line): Add a description of the new abilities
1331 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1332 "command sequence" vs. "recipe" syntax.
1333 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1334 after a define, to create variables with those flavors.
1336 2009-05-25 Paul Smith <psmith@gnu.org>
1338 Reworked the parser for variable assignments to allow multiple
1339 modifiers, and in any order. Also allows variable and
1340 prerequisites to be modifier names ('export', 'private', etc.)
1342 * NEWS: Add notes about user-visible changes.
1344 * read.c (struct vmodifiers): Remember what modifiers were seen.
1345 (parse_var_assignment): New function to parse variable assignments.
1346 (eval): Call the new function. Handle variable assignments earlier.
1348 * variable.c (parse_variable_definition): Only parse; don't create var.
1349 (assign_variable_definition): Call parse, then create the var.
1351 2009-05-24 Paul Smith <psmith@gnu.org>
1353 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1354 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1356 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1358 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1359 Fixes Savannah bug #25412.
1361 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1362 prototype for xmalloc.
1363 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1364 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1365 Loop over an array of extensions, instead of duplicating the same
1366 code inline. Use SearchPath followed by CreateFile, instead of
1367 the obsolete OpenFile. Fixes Savannah bug #17277.
1368 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1369 to `find_file'. Fixes Savannah bug #25662.
1371 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1373 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1374 Fixes Savannah bug #20495.
1376 2009-02-28 Ralf Wildenhues <address@hidden>

1379 -t with phony targets.
1381 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1383 Introduce a new keyword "private" which applies to target-specific
1384 variables and prevents their values from being inherited.
1386 * variable.h (struct variable): Add private_var flag to each variable.
1387 Add a flag to specify which list entry switches to the parent target.
1388 * variable.c (define_variable_in_set): Initialize private_var flag.

1407 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1409 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1412 * w32/subproc/build.bat (GCCBuild): Likewise.
1414 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1416 * job.c (construct_command_argv_internal): Avoid extra backslash
1417 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1420 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1422 * README.W32.template: Remove obsolete text about non-support for
1423 -jN without Unixy shell. Remove obsolete text about not supplying
1424 Visual Studio project files (we do supply them). Modify text to
1425 prefer GCC builds to MSC builds.
1427 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1429 * doc/make.texi (Empty Targets): Fix typo.
1431 2008-03-27 Paul Smith <psmith@gnu.org>

1444 `value' field is NULL.
1446 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1448 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1450 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1451 (TEXINFOS): Value changed to `doc/make.texi'.
1452 (.SUFFIXES): Use .texi instead of .texinfo.
1453 (make.info, make.dvi): Depend on doc/make.texi.
1454 (.texi.info): New target, instead of ".texinfo.info". Change -I
1455 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1456 (.texi): New target, instead of ".texinfo". Change -I switch to
1457 $(MAKEINFO) to look in doc/. Use --no-split.
1458 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1459 switch to $(MAKEINFO) to look in doc/.
1460 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1461 "*.i[0-9][0-9]" (due to --no-split above).

1463 (html, make_1.html): New targets.
1464 (.PHONY): Add "html".

1470 HAVE_DECL_SYS_SIGLIST.
1472 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1473 build does not use child_execute_job.
1475 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1476 export the SHELL environment variable to the child.
1478 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1480 * config.h.W32: Include sys/types.h.

1497 * remake.c (f_mtime): Print time difference values between 100 and
1498 ULONG_MAX in fixed-point notation rather than in exponention notation.
1500 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1502 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1503 a more complex value than a simple shell: if it's not a default
1504 shell now then expand it and see if is a default shell then.
1506 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1508 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1509 pathnames, with const strings.
1510 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1511 from the template (used for building from CVS, not a dist).
1513 2007-10-10 Paul Smith <psmith@gnu.org>
1515 * make.h: Add a prototype for w32_kill() (change suggested by
1516 Yongwei Wu <wuyongwei@gmail.com>).
1518 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1520 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1521 directories in Path.
1523 2007-09-12 Paul Smith <psmith@gnu.org>

1526 Provided by Diego Biurrun <diego@biurrun.de>
1527 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1528 Provided by Diego Biurrun <diego@biurrun.de>
1530 2007-09-11 Paul Smith <psmith@gnu.org>
1532 * doc/make.texi (Special Variables): Moved this into the "How to
1533 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1534 (MAKEFILE_LIST) No longer a section; this was added into the
1535 "Special Variables" section.
1536 (Rule Introduction): Reference .RECIPEPREFIX.
1537 (Simple Makefile): Ditto.
1538 (Rule Syntax): Ditto.
1539 (Command Syntax): Ditto.
1540 (Error Messages): Ditto.
1542 2007-09-10 Paul Smith <psmith@gnu.org>
1544 * commands.c (print_commands): Don't print an extra line in the
1545 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1547 * read.c (construct_include_path): Add the full string to the cache; we
1548 were chopping the last char.
1550 * NEWS: Announce the .RECIPEPREFIX special variable.
1551 * variable.c (lookup_special_var): Rename from handle_special_var().
1552 (lookup_variable): Call the new name.
1553 (set_special_var): New function: handle setting of special variables.
1554 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1555 (do_variable_definition): Call it.
1556 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1557 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1558 * main.c (main): Create the .RECIPEPREFIX special variable.
1559 * read.c (eval): Remove the cmd_prefix characters from the command
1560 scripts here, so they're not stored in the commands array at all,
1561 rather than waiting and stripping them out during command construction.
1562 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1564 2007-08-15 Paul Smith <psmith@gnu.org>
1566 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1567 file has had the section info removed, so add some to make.texi

1588 2007-07-13 Paul Smith <psmith@gnu.org>
1590 * file.c (expand_deps): Use variable_buffer as the start of the
1591 buffer, not the original pointer (in case it was reallocated).
1592 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1593 Fixes Savannah bug #20452.

1630 Dave Korn <dave.korn@artimi.com>
1632 2007-05-08 Paul Smith <psmith@gnu.org>
1634 Fix Savannah bug #19656:
1636 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1638 * make.h: Change all case-insensitive string compares to use
1639 strcasecmp() (from POSIX). If we don't have that but do have one
1640 of the others, define strcasecmp to be one of those instead. If
1641 we don't have any, declare a prototype for our own version.
1643 * misc.c (strcasecmp): Use this if we can't find any native
1644 case-insensitive string comparison function.
1645 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1646 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1648 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1649 strcasecmp() instead of stricmp().
1650 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1651 instead of strcmpi().
1652 * acinclude.m4: Remove the strcasecmp() check from here.
1654 2007-03-21 Paul Smith <psmith@gnu.org>
1656 * configure.in: Don't turn on case-insensitive file system support
1657 if --disable-... is given. Fixes Savannah bug #19348.
1659 2007-03-19 Paul Smith <psmith@gnu.org>
1661 * ALL: Use the strcache for all file name strings, or other
1662 strings which we will never free. The goal is to save memory by
1663 avoiding duplicate copies of strings. However, at the moment this
1664 doesn't save much memory in most situations: due to secondary
1665 expansion we actually save prerequisite lists twice (once before
1666 the secondary expansion, and then again after it's been parsed
1667 into individual file names in the dep list). We will resolve this
1668 in a future change, by doing the parsing up-front for targets
1669 where secondary expansion is not set.
1671 Moving things into the strcache also allows us to use const
1672 pointers in many more places.
1674 2007-01-03 Paul Smith <psmith@gnu.org>
1676 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1677 the function, not just the first. Fixes Savannah bug #18680.
1679 2006-11-18 Paul Smith <psmith@gnu.org>
1681 * strcache.c (strcache_add_len): Don't allocate a new buffer
1682 unless the string is not already nil-terminated. Technically this
1683 is a violation of the standard, since we may be passed an array
1684 that is not long enough to test one past. However, in make this
1685 is never true since we only use nil-terminated strings or
1686 sub-strings thereof.
1688 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1690 * main.c: New global cmd_prefix, defaults to '\t'.
1691 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1694 * dir.c: Constified.
1695 (dir_contents_file_exists_p): Check for an error return from
1696 readdir(), just in case.
1698 * commands.c: Constified.
1699 * default.c: Constified.
1700 * expand.c: Constified.
1701 * function.c: Partial constification.

1706 * w32/pathstuff.c: Partial constification.
1708 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1710 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1711 backslashes and drive letters as absolute.
1713 2006-10-22 Paul Smith <psmith@gnu.org>

1717 2006-10-21 Paul Smith <psmith@gnu.org>
1720 * arscan.c: Constified.
1722 2006-09-30 Paul Smith <psmith@gnu.org>
1724 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1725 point to lastword since the example was updated.
1726 Fixes Savannah bug #16304.
1727 (Secondary Expansion): Correct example description.
1728 Fixes Savannah bug #16468.
1729 (Makefile Contents): Clarify that comments cannot appear within
1730 variable references or function calls.
1731 Fixes Savannah bug #16577.
1732 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1733 Fixes Savannah bug #17701.
1734 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1736 prerequisites. Fixes Savannah bug #17880.
1737 (Rule Syntax): "lise" -> "list"
1738 (Multiple Rules): ... -> @dots{}
1739 (Splitting Lines): ditto.
1741 * remake.c (update_file_1): Prereqs that don't exist should be
1742 considered changed, for the purposes of $?.
1743 Fixes Savannah bug #16051.

1792 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1793 inner-scope variables don't mask outer-scope variables.

1854 Declare and define sh_chars_sh[].
1856 2006-03-23 Paul D. Smith <psmith@gnu.org>
1858 * configure.in: Look for build.sh.in in $srcdir so it will be
1859 built for remote configurations as well.
1861 * Makefile.am: Make sure to clean up build.sh during distclean.
1862 Fixes Savannah bug #16166.
1864 * misc.c (log_access): Takes a const char *.

1900 (free_dep_chain): Use free_dep.
1901 * read.c (record_files): Store stem in the dependency line.

1918 2006-03-09 Paul Smith <psmith@gnu.org>
1920 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1921 listed non-existent files as changed. Turns out there's a bug in
1922 the Linux kernel builds which means that this change causes
1923 everything to rebuild every time. We will re-introduce this fix
1924 in the next release, to give them time to fix their build system.

1945 * commands.c (set_file_variables): Realloc, not malloc, the static
1946 string values to avoid memory leaks.
1948 * expand.c (recursively_expand_for_file): Only set reading_file to
1949 an initialized value.
1951 * implicit.c (pattern_search): We need to make a copy of the stem

1963 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1964 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1965 the calls to _beginthreadex.
1967 * expand.c (recursively_expand_for_file): Initialize `save' to
1968 prevent compiler warnings.
1970 2006-02-18 Eli Zaretskii <eliz@gnu.org>

1974 script file stream to text mode.

1978 * variable.c (merge_variable_set_lists): Don't try to merge the
1979 global_setlist. Not only is this useless, but it can lead to
1980 circularities in the linked list, if global_setlist->next in one
1981 list gets set to point to another list which also ends in

1987 Fix for Savannah bug #106.

1990 expanding. If no variable is being expanded, it's the same as
1992 * make.h (expanding_var): Declare it.
1993 * expand.c (recursively_expand_for_file): Set expanding_var to the
1994 current variable we're expanding, unless there's no file info in
1995 it (could happen if it comes from the command line or a default
1996 variable). Restore it before we exit.

2012 an impossible file, free it.
2013 * variable.c (free_variable_set): New function.
2014 * variable.h: Declare it.
2016 * read.c (read_all_makefiles): Makefile names are kept in the
2017 strcache, so there's never any need to alloc/free them.
2020 * main.c (main): Add "archives" to the .FEATURES variable if
2021 archive support is enabled.

2032 * (ALL FILES): Updated copyright and license notices.
2034 2006-02-10 Paul D. Smith <psmith@gnu.org>
2036 A new internal capability: the string cache is a read-only cache
2037 of strings, with a hash table interface for fast lookup. Nothing
2038 in the cache will ever be freed, so there's no need for reference
2039 counting, etc. This is the beginning of a full solution for
2040 Savannah bug #15182, but for now we only store makefile names here.

2094 to avoid walking the list every time we want to add a new one.
2095 Fixes Savannah bug #15533.
2096 * filedef.h (struct file): Add a new LAST pointer.
2098 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
2099 the comparison. For 64-bits systems the result of the subtraction
2100 might not fit into an int. Use comparison instead.
2101 Fixes Savannah bug #15534.
2103 * doc/make.texi: Update the chapter on writing commands to reflect
2104 the changes made in 3.81 for backslash/newline and SHELL handling.
2106 2006-02-01 Paul D. Smith <psmith@gnu.org>
2108 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
2109 variable st is not used when it's not initialized.
2110 Patch from Eli Zaretskii <eliz@gnu.org>.
2112 2006-01-31 Paul D. Smith <psmith@gnu.org>
2114 * README.W32.template: Applied patch #4785 from
2115 Markus Mauhart <qwe123@chello.at>.

2122 * prepare_w32.bat: Remove this file from the distribution.
2124 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2126 * remake.c (update_goal_chain): Set g->changed instead of
2127 incrementing it, as it is only 8-bit wide, and could overflow if
2128 many commands got started in update_file.
2130 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
2132 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
2133 MAXIMUM_WAIT_OBJECTS.
2134 (process_wait_for_any_private): Change dimension of handles[]
2135 array to MAXIMUM_WAIT_OBJECTS.
2136 (process_used_slots): New function.
2137 (process_register): Don't register more processes than the
2138 available number of slots.
2139 (process_easy): Don't start new processes if all slots are used up.
2141 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
2142 are already more children than sub_proc.c can handle, behave as if
2143 the load were too high.
2144 (start_job_command): Fix a typo in error message when process_easy
2147 2006-01-14 Eli Zaretskii <eliz@gnu.org>
2149 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
2150 the shell is not sh.exe.
2152 * job.c (create_batch_file): Renamed from create_batch_filename;
2153 all callers changed. Don't close the temporary file; return its
2154 file descriptor instead. New arg FD allows to return the file
2156 (construct_command_argv_internal): Use _fdopen instead of fopen to
2157 open the batch file.
2159 2006-01-04 Paul D. Smith <psmith@gnu.org>
2161 * readme.vms: Updates for case-insensitive VMS file systems from
2162 Hartmut Becker <Hartmut.Becker@hp.com>.
2163 * dir.c (vms_hash): Ditto.
2164 * vmsify.c (copyto): Ditto.
2165 * vmsfunctions.c (readdir): Ditto.
2167 * make.1: Add a section on the exit codes for make.
2169 * doc/make.texi: A number of minor updates to the documentation.
2171 2006-01-03 Paul D. Smith <psmith@gnu.org>
2173 * remake.c (update_file_1): Mark a prerequisite changed if it
2176 * read.c (eval): Be sure to strip off trailing whitespace from the
2177 prerequisites list properly. Also, initialize all fields in
2178 struct dep when creating a new one.
2180 2005-12-28 Paul D. Smith <psmith@gnu.org>
2182 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2183 disable warnings for MSC.
2184 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2186 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2188 * doc/make.texi (Execution): Add a footnote about changes in
2189 handling of backslash-newline sequences. Mention the differences
2190 on MS-DOS and MS-Windows.
2192 * NEWS: More details about building the MinGW port and a pointer
2193 to README.W32. Fix the section name that describes the new
2194 backward-incompatible processing of backslash-newline sequences.
2195 The special processing of SHELL set to "cmd" is only relevant to
2196 MS-Windows, not MS-DOS.
2198 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2200 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2201 to DWORD, to avoid compiler warnings.
2202 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2203 use %ld in format, to avoid compiler warnings.
2205 * doc/make.texi (Special Targets): Fix a typo.
2206 (Appending): Fix cross-reference to Setting.
2207 (Special Variables, Secondary Expansion, File Name Functions)
2208 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2209 periods after a sentence.
2210 (Execution): Add @: after "e.g.".
2211 (Environment): Fix punctuation.
2212 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2213 (Shell Function, Target-specific): Add @: after "vs."
2215 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2217 * read.c (record_target_var): Initialize variable's export field
2218 with v_default instead of leaving it "initialized" by whatever
2219 garbage happened to be on the heap.
2221 2005-12-12 Paul D. Smith <psmith@gnu.org>
2223 * make.1: Fix some display errors and document all existing options.
2224 Patch by Mike Frysinger <vapier@gentoo.org>.
2226 2005-12-11 Paul D. Smith <psmith@gnu.org>
2228 * implicit.c (pattern_search): If 2nd expansion is not set for
2229 this implicit rule, replace the pattern with the stem directly,
2230 and don't re-expand the variable list. Along with the other
2231 .SECONDEXPANSION changes below, fixes bug #13781.
2233 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2235 * implicit.c (pattern_search): Mark other files that this rule
2236 builds as targets so that they are not treated as intermediates
2237 by the pattern rule search algorithm. Fixes bug #13022.
2239 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2241 * remake.c (notice_finished_file): Propagate the change of
2242 modification time to all the double-colon entries only if
2243 it is the last one to be updated. Fixes bug #14334.
2245 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2247 * function.c (func_flavor): Implement the flavor function which
2248 returns the flavor of a variable.
2249 * doc/make.texi (Functions for Transforming Text): Document it.
2250 * NEWS: Add it to the list of new functions.
2252 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2254 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2256 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2257 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2259 2005-10-26 Paul Smith <psmith@gnu.org>
2261 * read.c (record_files): Don't set deps flags if there are no deps.
2262 * maintMakefile: We only need to build the templates when we are
2263 creating a distribution, so don't do it for "all".
2265 2005-10-24 Paul D. Smith <psmith@gnu.org>
2267 Make secondary expansion optional: its enabled by declaring the
2268 special target .SECONDEXPANSION.
2270 * NEWS: Update information on second expansion capabilities.
2271 * doc/make.texi (Secondary Expansion): Document the
2272 .SECONDEXPANSION special target and its behavior.
2273 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2274 prerequisite list was found in a static pattern rule.
2275 (free_dep_chain): Declare a prototype.
2276 * file.c (parse_prereqs): New function: break out some complexity
2278 (expand_deps): If we aren't doing second expansion, replace % with
2279 the stem for static pattern rules. Call the new function.
2280 * filedef.h (parse_prereqs): Declare a prototype.
2281 * implicit.c (pattern_search): Initialize the new staticpattern
2283 * main.c (second_expansion): Declare a global variable to remember
2284 if the special target has been seen. Initialize the new
2285 staticpattern field for prerequisites.
2286 * make.h: Extern for second_expansion.
2287 * misc.c (free_dep_chain): New function: frees a struct dep list.
2288 * read.c (read_all_makefiles): Initialize the staticpattern field.
2289 (eval_makefile): Ditto.
2290 (record_files): Check for the .SECONDEXPANSION target and set
2291 second_expansion global if it's found.
2292 Use the new free_dep_chain() instead of doing it by hand.
2293 Set the staticpattern field for prereqs of static pattern targets.
2295 2005-10-16 Paul D. Smith <psmith@gnu.org>
2297 * main.c (main): Set CURDIR to be a file variable instead of a
2298 default, so that values of CURDIR inherited from the environment
2299 won't override the make value.
2301 2005-09-26 Paul D. Smith <psmith@gnu.org>
2303 * job.c (construct_command_argv_internal): If the line is empty
2304 remember to free the temporary argv strings.
2307 2005-09-16 Paul D. Smith <psmith@gnu.org>
2309 * job.c (start_job_command): The noerror flag is a boolean (single
2310 bit); set it appropriately.
2311 Reported by Mark Eichin <eichin@metacarta.com>
2313 2005-08-29 Paul D. Smith <psmith@gnu.org>
2315 * function.c (func_error): On Windows, output from $(info ...)
2316 seems to come in the wrong order. Try to force it with fflush().
2318 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2320 * read.c (record_files): Move code that sets stem for static
2321 pattern rules out of the if (!two_colon) condition so it is
2322 also executed for two-colon rules. Fixes Savannah bug #13881.
2324 2005-08-08 Paul D. Smith <psmith@gnu.org>
2326 * make.h: Don't test that __STDC__ is non-0. Some compilers
2327 (Windows for example) set it to 0 to denote "ISO C + extensions".
2330 2005-08-07 Paul D. Smith <psmith@gnu.org>
2332 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2333 conditional (slightly different version of a fix from Eli).
2335 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2336 If make is running in parallel without -k and two jobs die in a
2337 row, but not too close to each other, then make will quit without
2338 waiting for the rest of the jobs to die.
2340 * main.c (die): Don't reset err before calling reap_children() the
2341 second time: we still want it to be in the error condition.
2342 * job.c (reap_children): Use a static variable, rather than err,
2343 to control whether or not the error message should be printed.
2345 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2347 * w32/subproc/sub_proc.c: Include signal.h.
2348 (process_pipe_io, process_file_io): Pass a pointer to a local
2349 DWORD variable to GetExitCodeProcess. If the exit code is
2350 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2352 * job.c [WINDOWS32]: Include windows.h.
2353 (main_thread) [WINDOWS32]: New global variable.
2354 (reap_children) [WINDOWS32]: Get the handle for the main thread
2355 and store it in main_thread.
2357 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2358 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2359 doing anything else. When we are done, close the main thread
2360 handle and exit with status 130.
2362 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2364 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2367 * main.c (find_and_set_default_shell): If found a DOSish shell,
2368 set sh_found and the value of default_shell, and report the
2369 findings in debug mode.
2371 * job.c (construct_command_argv_internal): Check unixy_shell, not
2372 no_default_sh_exe, to decide whether to use Unixy or DOSish
2375 * README.W32: Update with info about the MinGW build.
2377 * build_w32.bat: Support MinGW.
2379 * w32/subproc/build.bat: Likewise.
2381 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2382 printing DWORD args.
2384 * function.c (windows32_openpipe): Fix format strings for printing
2387 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2389 (start_job_command): Fix format string for printing the result of
2391 (start_job_command) [WINDOWS32]: Do not define.
2392 (exec_command): Fix format string for printing HANDLE args.
2394 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2395 to avoid compiler warnings.
2396 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2397 (Note: some of these fixes were submitted independently by J. Grant)
2399 2005-07-30 J. Grant <jg@jguk.org>
2401 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2402 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2403 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2405 2005-07-15 Paul Smith <psmith@gnu.org>
2407 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2408 we don't have a POSIX shell, then revert to the old
2409 backslash-newline behavior (where they are stripped).
2412 2005-07-08 Paul D. Smith <psmith@gnu.org>
2414 * config.h.W32.template: Reorder to match the standard config.h,
2415 for easier comparisons.
2416 From J. Grant <jg@jguk.org>
2418 * maintMakefile: Remove .dep_segment before overwriting it, in
2419 case it's not writable or noclobber is set.
2420 * expand.c (variable_expand_string): Cast result of pointer
2421 arithmetic to avoid a warning.
2422 * main.c (switches): Add full-fledged final initializer.
2424 2005-07-06 Paul D. Smith <psmith@gnu.org>
2426 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2427 * signame.c (strsignal): If we found _sys_siglist[] or
2428 __sys_siglist[] use those instead of sys_siglist[].
2429 From Albert Chin <china@thewrittenword.com>
2431 2005-07-04 Paul D. Smith <psmith@gnu.org>
2433 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2434 globfree(); set up to use the GNU versions.
2435 From Martin Zinser <zinser@zinser.no-ip.info>
2437 2005-07-03 Paul D. Smith <psmith@gnu.org>
2439 From J. Grant <jg@jguk.org>:
2441 * README.W32.template: Update the Windows and tested MSVC versions.
2442 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2443 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2444 * build_w32.bat: Ditto.
2445 * w32/subproc/build.bat: Ditto.
2447 2005-06-28 Paul D. Smith <psmith@gnu.org>
2449 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2450 declaration was checked but not present.
2452 2005-06-27 Paul D. Smith <psmith@gnu.org>
2454 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2455 to unsigned long. Fixes Savannah bug #13550.
2457 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2458 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2459 Fixes Savannah bug #13551.
2461 2005-06-26 Paul D. Smith <psmith@gnu.org>
2463 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2464 it if ANSI_STRING is not set.
2466 2005-06-25 Paul D. Smith <psmith@gnu.org>
2468 * read.c (eval): If no filenames are passed to any of the
2469 "include" variants, don't print an error.
2470 * doc/make.texi (Include): Document this.
2471 Fixes Savannah bug #1761.
2473 * job.c (construct_command_argv_internal): Sanitize handling of
2474 backslash/newline pairs according to POSIX: that is, keep the
2475 backslash-newline in the command script, but remove a following
2476 TAB character, if present. In the fast path, make sure that the
2477 behavior matches what the shell would do both inside and outside
2478 of quotes. In the slow path, quote the backslash and put a
2479 literal newline in the string.
2480 Fixes Savannah bug #1332.
2481 * doc/make.texi (Execution): Document the new behavior and give
2483 * NEWS: Make a note of the new behavior.
2485 * make.h [WINDOWS32]: #include <direct.h>.
2486 Fixes Savannah bug #13478.
2488 * remake.c (name_mtime): If the stat() of a file fails and the -L
2489 option was given and the file is a symlink, take the best mtime of
2490 the symlink we can get as the mtime of the file and don't fail.
2491 Fixes Savannah bug #13280.
2493 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2494 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2495 inside a variable reference. Make this function static as it's
2497 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2498 parsing an unexpanded line looking for semicolons.
2499 Fixes Savannah bug #1454.
2500 * misc.c (remove_comments): Move this to read.c and make it static
2501 as it's only used there. Call find_char_unquote() with new arg.
2502 * make.h: Remove prototypes for find_char_unquote() and
2503 remove_comments() since they're static now.
2505 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2506 its export flag and obtain its value. When we need to re-exec,
2507 increment the value and add it into the environment.
2508 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2509 * NEWS: Mention MAKE_RESTARTS.
2510 * main.c (always_make_set): New variable. Change the -B option to
2511 set this one instead.
2512 (main): When checking makefiles, only set always_make_flag if
2513 always_make_set is set AND the restarts flag is 0. When building
2514 normal targets, set it IFF always_make_set is set.
2515 (main): Avoid infinite recursion with -W, too: only set what-if
2516 files to NEW before we check makefiles if we've never restarted
2517 before. If we have restarted, set what-if files to NEW _after_ we
2519 Fixes Savannah bug #7566:
2521 2005-06-17 Paul D. Smith <psmith@gnu.org>
2523 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2524 in the prerequisites list.
2526 2005-06-12 Paul D. Smith <psmith@gnu.org>
2528 Fix Savannah bug # 1328.
2530 * configure.in: Check for atexit().
2531 * misc.c (close_stdout): Test stdout to see if writes to it have
2532 failed. If so, be sure to exit with a non-0 error code. Based on
2533 code found in gnulib.
2534 * make.h: Prototype.
2535 * main.c (main): Install close_stdout() with atexit().
2537 2005-06-10 Paul D. Smith <psmith@gnu.org>
2539 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2541 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2542 headers; make vmsWaitForChildren() static; extern vmsify().
2543 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2544 Don't create child_execute_job() here (it's in vmsjobs.c).
2545 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2547 2005-06-09 Paul D. Smith <psmith@gnu.org>
2549 * variable.c (push_new_variable_scope): File variables point
2550 directly to the global_setlist variable. So, inserting a new
2551 scope in front of that has no effect on those variables: they
2552 don't go through current_variable_set_list. If we're pushing a
2553 scope and the current scope is global, push it "the other way" so
2554 that the new setlist is in the global_setlist variable, and
2555 next points to a new setlist with the global variable set.
2556 (pop_variable_scope): Properly undo a push with the new
2558 Fixes Savannah bug #11913.
2560 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2562 * job.c (reap_children): Don't die of the command failed but
2563 the dontcare flag is set. Fixes Savannah bug #13216.
2565 * implicit.c (pattern_search): When creating a target from
2566 an implicit rule match, lookup pattern target and set precious
2567 flag in a newly created target. Fixes Savannah bug #13218.
2569 2005-05-13 Paul D. Smith <psmith@gnu.org>
2571 Implement "if... else if... endif" syntax.
2573 * read.c (eval): Push all checks for conditional words ("ifeq",
2574 "else", etc.) down into the conditional_line() function.
2575 (conditional_line): Rework to allow "else if..." clause. New
2576 return value -2 for lines which are not conditionals. The
2577 ignoring flag can now also be 2, which means "already parsed a
2578 true branch". If that value is seen no other branch of this
2579 conditional can be considered true. In the else parsing if there
2580 is extra text after the else, invoke conditional_line()
2581 recursively to see if it's another conditional. If not, it's an
2582 error. If so, raise the conditional value to this level instead
2583 of creating a new conditional nesting level. Special check for
2584 "else" and "endif", which aren't allowed on the "else" line.
2585 * doc/make.texi (Conditional Syntax): Document the new syntax.
2587 2005-05-09 Paul D. Smith <psmith@gnu.org>
2589 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2590 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2591 recurses to the w32 directory, even on non-Windows systems. Use
2592 the method suggested in the automake manual.
2593 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2594 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2596 2005-05-07 Paul D. Smith <psmith@gnu.org>
2598 * main.c (die): If we're dying with a fatal error (not that a
2599 command has failed), write back any leftover tokens before we go.
2601 * job.c (set_child_handler_action_flags): If there are jobs
2602 waiting for the load to go down, set an alarm to go off in 1
2603 second. This allows us to wake up from a potentially long-lasting
2604 read() and start a new job if the load has gone down. Turn it off
2606 (job_noop): Dummy signal handler function.
2607 (new_job): Invoke it with the new semantics.
2609 * docs/make.texi: Document secondary expansion. Various cleanups
2612 2005-05-03 Paul D. Smith <psmith@gnu.org>
2614 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2615 the targets which are to ultimately be made are called "goals";
2616 see the GNU make manual. Also, MAKECMDGOALS, etc.
2618 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2619 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2620 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2622 2005-05-02 Paul D. Smith <psmith@gnu.org>
2624 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2625 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2626 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2627 functions to vmsjobs.c. #include it into jobs.c.
2629 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2630 jobserver tokens. I found that this happens when an exported
2631 recursive variable contains a $(shell ...) function reference: in
2632 this situation we could "forget" to write back a token.
2634 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2635 we have. It's not reliable to depend on the number of children in
2636 our linked list so keep a separate count.
2637 (new_job): Check jobserver_tokens rather than children &&
2638 waiting_jobs. Increment jobserver_tokens when we get one.
2639 (free_child): If jobserver_tokens is 0, internal error. If it's
2640 >1, write a token back to the jobserver pipe (we don't write a
2641 token for the "free" job). Decrement jobserver_tokens.
2643 * main.c: Add variable master_job_slots.
2644 (main): Set it to hold the number of jobs requested if we're the
2645 master process, when using the jobserver.
2646 (die): Sanity checks: first test jobserver_tokens to make sure
2647 this process isn't holding any tokens we didn't write back.
2648 Second, if master_job_slots is set count the tokens left in the
2649 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2651 2005-04-24 Paul D. Smith <psmith@gnu.org>
2653 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2654 with -l# can lose jobserver tokens, because waiting jobs are not
2655 consulted properly when checking for the "free" token.
2657 * job.c (free_child): Count waiting_jobs as having tokens.
2658 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2659 handle jobs waiting for the load to drop.
2661 2005-04-23 Paul D. Smith <psmith@gnu.org>
2663 * main.c (main): Be careful to not core if a variable setting in
2664 the environment doesn't contain an '='. This is illegal but can
2665 happen in broken setups.
2666 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2668 2005-04-12 Paul D. Smith <psmith@gnu.org>
2670 The second expansion feature causes significant slowdown. Timing
2671 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2672 read the makefile before the feature, to 11+s to do the same
2673 operations after the feature. Additionally, memory usage
2674 increased drastically. To fix this I added some intelligence that
2675 avoids the overhead of the second expansion unless it's required.
2677 * dep.h: Add a new boolean field, need_2nd_expansion.
2679 * read.c (eval): When creating the struct dep for the target,
2680 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2681 (record_files): If there's a "%" in a static pattern rule, it gets
2682 converted to "$*" so set need_2nd_expansion to 1.
2684 * file.c (expand_deps): Rework to be more efficient. Only perform
2685 initialize_file_variables(), set_file_variables(), and
2686 variable_expand_for_file() if the need_2nd_expansion is set.
2688 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2689 (pattern_search): Ditto.
2690 * main.c (handle_non_switch_argument): Ditto.
2692 * read.c (read_all_makefiles): Ditto.
2693 (eval_makefile): Ditto.
2695 2005-04-07 Paul D. Smith <psmith@gnu.org>
2697 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2698 * variable.c (sync_Path_environment): Ditto.
2699 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2701 * main.c (main): Define the .FEATURES variable.
2702 * NEWS: Announce .FEATURES.
2703 * doc/make.texi (Special Variables): Document .FEATURES.
2705 * remake.c (check_dep): If a file is .PHONY, update it even if
2706 it's marked intermediate. Fixes Savannah bug #12331.
2708 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2710 * file.c (expand_deps): Factor out the second expansion and
2711 prerequisite line parsing logic from snap_deps().
2713 * file.c (snap_deps): Use expand_deps(). Expand and parse
2714 prerequisites of the .SUFFIXES special target first. Fixes
2715 Savannah bug #12320.
2717 2005-03-13 Paul D. Smith <psmith@gnu.org>
2719 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2722 2005-03-11 Paul D. Smith <psmith@gnu.org>
2724 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2725 available, not undefined (from Earnie Boyd).
2727 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2729 * implicit.c (pattern_search): Mark an intermediate target as
2730 precious if it happened to be a prerequisite of some (other)
2731 target. Fixes Savannah bug #12267.
2733 2005-03-09 Paul D. Smith <psmith@gnu.org>
2735 * read.c (eval_makefile): Add alloca(0).
2736 (eval_buffer): Ditto.
2738 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2740 * main.c (main): Use o_file instead of o_default when defining
2741 the .DEFAULT_TARGET special variable.
2742 * read.c (eval): Use define_variable_global() instead of
2743 define_variable() when setting new value for the .DEFAULT_TARGET
2744 special variable. Fixes Savannah bug #12266.
2746 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2748 * imlicit.c (pattern_search): Mark files for which an implicit
2749 rule has been found as targets. Fixes Savannah bug #12202.
2751 2005-03-04 Paul D. Smith <psmith@gnu.org>
2754 * doc/make.texi (Automatic Variables): Document $|.
2756 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2758 * read.c (record_files): Instead of substituting % with
2759 actual stem value in dependency list replace it with $*.
2760 This fixes stem triple expansion bug.
2762 * implicit.c (pattern_search): Copy stem to a separate
2763 buffer and make it a properly terminated string. Assign
2764 this buffer instead of STEM (which is not terminated) to
2765 f->stem. Instead of substituting % with actual stem value
2766 in dependency list replace it with $*. This fixes stem
2767 triple expansion bug.
2769 2005-03-01 Paul D. Smith <psmith@gnu.org>
2771 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2772 on Windows, as it takes a handle not a pid. Just exit.
2773 Fix from patch #3679, provided by Alessandro Vesely.
2775 * configure.in: Update check for sys_siglist[] from autoconf manual.
2776 * signame.c (strsignal): Update to use the new autoconf macro.
2778 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2780 * read.c (record_files): Add a check for the list of prerequisites
2781 of a static pattern rule being empty. Fixes Savannah bug #12180.
2783 2005-02-28 Paul D. Smith <psmith@gnu.org>
2785 * doc/make.texi (Text Functions): Update docs to allow the end
2786 ordinal for $(wordlist ...) to be 0.
2787 * function.c (func_wordlist): Fail if the start ordinal for
2788 $(wordlist ...) is <1. Matches documentation.
2789 Resolves Savannah support request #103195.
2791 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2792 previously we were stopping when !-q, exactly the opposite. This
2793 has been wrong since version 1.34, in 1994!
2794 (update_file): If we got an error don't break out to run more
2795 double-colon rules: just return immediately.
2796 Fixes Savannah bug #7144.
2798 2005-02-27 Paul D. Smith <psmith@gnu.org>
2800 * misc.c (end_of_token): Make argument const.
2801 * make.h: Update prototype.
2803 * function.c (abspath, func_realpath, func_abspath): Use
2804 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2805 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2806 * read.c (record_files): Ditto.
2807 * variable.c (do_variable_definition): Ditto.
2809 * function.c (func_error): Create a new function $(info ...) that
2810 simply prints the message to stdout with no extras.
2811 (function_table_init): Add new function to the table.
2812 * NEWS: Add $(info ...) reference.
2813 * doc/make.texi (Make Control Functions): Document it.
2815 New feature: if the system supports symbolic links, and the user
2816 provides the -L/--check-symlink-time flag, then use the latest
2817 mtime between the symlink(s) and the target file.
2819 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2820 readlink(). If both are available, define MAKE_SYMLINKS.
2821 * main.c: New variable: check_symlink_flag.
2822 (usage): Add a line for -L/--check-symlink-times to the help string.
2823 (switches): Add -L/--check-symlink-times command line argument.
2824 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2825 print a warning and disable it again.
2826 * make.h: Declare check_symlink_flag.
2827 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2828 if the file is a symlink then check each link in the chain and
2829 choose the NEWEST mtime we find as the mtime for the file. The
2830 newest mtime might be the file itself!
2831 * NEWS: Add information about this new feature.
2832 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2834 Avoid core dumps described in Savannah bug # 12124:
2836 * file.c: New variable snapped_deps remember whether we've run
2838 (snap_deps): Set it.
2839 * filedef.h: Extern it.
2840 * read.c (record_files): Check snapped_deps; if it's set then
2841 we're trying to eval a new target/prerequisite relationship from
2842 within a command script, which we don't support. Fatal.
2844 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2846 Implementation of the .DEFAULT_TARGET special variable.
2848 * read.c (eval): If necessary, update default_target_name when
2850 * read.c (record_files): Update default_target_file if
2851 default_target_name has changed.
2852 * main.c (default_target_name): Define.
2853 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2854 default_target_name is set use default_target_file as a root
2856 * filedef.h (default_target_name): Declare.
2857 * dep.h (free_dep_chain):
2858 * misc.c (free_dep_chain): Change to operate on struct nameseq
2859 and change name to free_ns_chain.
2860 * file.c (snap_deps): Update to use free_ns_chain.
2862 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2864 Implementation of the second expansion in explicit rules,
2865 static pattern rules and implicit rules.
2867 * read.c (eval): Refrain from chopping up rule's dependencies.
2868 Store them in a struct dep as a single dependency line. Remove
2869 the code that implements SySV-style automatic variables.
2871 * read.c (record_files): Adjust the code that handles static
2872 pattern rules to expand all percents instead of only the first
2873 one. Reverse the order in which dependencies are stored so that
2874 when the second expansion reverses them again they appear in
2875 the makefile order (with some exceptions, see comments in
2876 the code). Remove the code that implements SySV-style automatic
2879 * file.c (snap_deps): Implement the second expansion and chopping
2880 of dependency lines for explicit rules.
2882 * implicit.c (struct idep): Define an auxiliary data type to hold
2883 implicit rule's dependencies after stem substitution and
2886 * implicit.c (free_idep_chain): Implement.
2888 * implicit.c (get_next_word): Implement helper function for
2889 parsing implicit rule's dependency lines into words taking
2890 into account variable expansion requests. Used in the stem
2893 * implicit.c (pattern_search): Implement the second expansion
2894 for implicit rules. Also fixes bug #12091.
2896 * commands.h (set_file_variables): Declare.
2897 * commands.c (set_file_variables): Remove static specifier.
2899 * dep.h (free_dep_chain): Declare.
2900 * misc.c (free_dep_chain): Implement.
2902 * variable.h (variable_expand_for_file): Declare.
2903 * expand.c (variable_expand_for_file): Remove static specifier.
2905 * make.h (strip_whitespace): Declare.
2906 * function.c (strip_whitespace): Remove static specifier.
2908 2005-02-26 Paul D. Smith <psmith@gnu.org>
2910 * main.c (main): Check for ferror() when reading makefiles from stdin.
2911 Apparently some shells in Windows don't close pipes properly and
2914 2005-02-24 Jonathan Grant <jg@jguk.org>
2916 * configure.in: Add MinGW configuration options, and extra w32 code
2918 * Makefile.am: Add MinGW configuration options, and extra w32 code
2920 * main.c: Determine correct program string (after last \ without .exe).
2921 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2923 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2924 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2925 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2926 environment support.
2928 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2930 * function.c (func_shell): When initializing error_prefix, check
2931 that reading file name is not null. This fixes long-standing
2932 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2934 2005-02-09 Paul D. Smith <psmith@gnu.org>
2936 * maintMakefile: Update the CVS download URL to simplify them.
2937 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2938 downloading the .texi files from Savannah now.
2940 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2942 * main.c (handle_non_switch_argument): Only add variables to
2943 command_variables if they're not already there: duplicate settings
2944 waste space and can be confusing to read.
2946 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2947 this header is never included by non-WINDOWS32 code, and it
2948 requires <config.h> to define which isn't always included first.
2950 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2951 testing MINGW32 versions.
2953 * main.c (log_working_directory): flush stdout to be sure the WD
2954 change is printed before any stderr messages show up.
2956 2005-02-01 Paul D. Smith <psmith@gnu.org>
2958 * maintMakefile (po_repo): Update the GNU translation site URL.
2960 2004-12-01 Paul D. Smith <psmith@gnu.org>
2962 * main.c (main): Change char* env_shell to struct variable shell_var.
2963 * variable.c (target_environment): Use new shell_var.
2965 2004-11-30 Paul D. Smith <psmith@gnu.org>
2967 * configure.in: The old way we avoided creating build.sh from
2968 build.sh.in before build.sh.in exists doesn't work anymore; we
2969 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2970 the help!). This also keeps automake from complaining.
2971 * Makefile.am (README): Add a dummy target so automake won't
2972 complain that this file doesn't exist when we checkout from CVS.
2973 * maintMakefile (.dep_segment): Rewrite this rule since newer
2974 versions of automake don't provide DEP_FILES.
2976 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2978 Implementation of `realpath' and `abspath' built-in functions.
2980 * configure.in: Check for realpath.
2981 * function.c (abspath): Return an absolute file name that does
2982 not contain any `.' or `..' components, nor repeated `/'.
2983 * function.c (func_abspath): For each name call abspath.
2984 * function.c (func_realpath): For each name call realpath
2985 from libc or delegate to abspath if realpath is not available.
2986 * doc/make.texi (Functions for File Names): Document new functions.
2987 * doc/make.texi (Quick Reference): Ditto.
2989 2004-11-28 Paul D. Smith <psmith@gnu.org>
2991 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2992 arguments. Fixes bug #10252.
2994 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2996 * main.c (main): Set SHELL to v_noexport by default. Remember the
2997 original environment setting of SHELL in the env_shell variable.
2998 * main.h: Export new env_shell variable.
2999 * variable.c (target_environment): If we find a v_noexport
3000 variable for SHELL, add a SHELL variable with the env_shell value.
3001 * doc/make.texi (Quick Reference): Document the POSIX behavior.
3002 * doc/make.texi (Variables/Recursion): Ditto.
3004 2004-11-28 Paul D. Smith <psmith@gnu.org>
3006 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
3007 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
3008 Patch by Alessandro Vesely.
3010 2004-11-12 Paul D. Smith <psmith@gnu.org>
3012 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
3013 the command line if it's inside a string.
3014 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
3016 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
3018 * function.c (func_lastword): New function: return last word
3019 from the list of words.
3020 * doc/make.texi: Document $(lastword ). Fix broken links in
3021 Quick Reference section.
3023 2004-10-06 Paul D. Smith <psmith@gnu.org>
3025 Apply patch from Alessandro Vesely, provided with bug # 9748.
3026 Fix use of tmpnam() to work with Borland C.
3028 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
3029 construction of a temporary filename, and call new function
3030 create_batch_filename().
3031 (create_batch_filename) [WINDOWS32]: New function to create a
3034 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
3036 * read.c (record_target_var): Expand simple pattern-specific
3038 * variable.c (initialize_file_variables): Do not expand simple
3039 pattern-specific variable.
3041 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
3043 * remake.c (update_file_1): When rebuilding makefiles inherit
3044 dontcare flag from a target that triggered update.
3046 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
3048 * variable.c (initialize_file_variables): Mark pattern-specific
3049 variable as a per-target and copy export status.
3051 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
3053 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
3055 * implicit.c (pattern_search): When considering an implicit rule's
3056 prerequisite check that it is actually a target rather then
3057 just an entry in the file hashtable.
3059 2004-09-21 Paul D. Smith <psmith@gnu.org>
3061 * read.c (readstring): Fix some logic errors in backslash handling.
3062 (eval): Remove some unnecessary processing in buffer handling.
3063 (record_target_var): Assert that parse_variable_definition() succeeded.
3064 Reported by: Markus Mauhart <qwe123@chello.at>.
3066 * misc.c: Removed the sindex() function. All instances of this
3067 function were trivially replaceable by the standard strstr()
3068 function, and that function will always have better (or certainly
3069 no worse) performance than the very simple-minded algorithm
3070 sindex() used. This can matter with complex makefiles.
3071 * make.h: Remove the prototype for sindex().
3072 * function.c (subst_expand): Convert sindex() call to strstr().
3073 This means we no longer need to track the TLEN value so remove that.
3074 (func_findstring): Convert sindex() to strstr().
3075 * commands.c (chop_commands): Convert sindex() calls to strstr().
3076 Suggested by: Markus Mauhart <qwe123@chello.at>.
3078 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
3079 idea behind Savannah Patch #3144 from david.baird@homemail.com.
3080 If SHELL is set to CMD.EXE then assume it's batch-mode and
3081 non-unixy. I wrote the code differently from the patch, though,
3082 to make it safer. This also resolves bug #9174.
3084 2004-09-20 Paul D. Smith <psmith@gnu.org>
3086 * expand.c (variable_expand_string): Modify to invoke
3087 patsubst_expand() instead of subst_expand(); the latter didn't
3088 handle suffix patterns correctly.
3089 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
3090 was used only from variable_expand_string() and is no longer used
3092 (func_subst): Ditto, on call to subst_expand().
3093 (patsubst_expand): Require the percent pointers to point to the
3094 character after the %, not to the % itself.
3095 * read.c (record_files): New call criteria for patsubst_expand().
3096 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
3097 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
3099 2004-09-19 Paul D. Smith <psmith@gnu.org>
3101 * function.c (subst_expand): Fix a check in by_word: look for a
3102 previous blank if we're beyond the beginning of the string, not
3103 the beginning of the word.
3104 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3106 2004-05-16 Paul D. Smith <psmith@gnu.org>
3108 * remake.c (update_goal_chain): Change the argument specifying
3109 whether we're rebuilding makefiles to be a global variable,
3110 REBUILDING_MAKEFILES.
3111 (complain): Extract the code that complains about no rules to make
3112 a target into a separate function.
3113 (update_file_1): If we tried to rebuild a file during the makefile
3114 rebuild phase and it was dontcare, then no message was printed.
3115 If we then try to build the same file during the normal build,
3116 print a message this time.
3117 (remake_file): Don't complain about un-remake-able files when
3118 we're rebuilding makefiles.
3120 2004-05-11 Paul D. Smith <psmith@gnu.org>
3122 * job.c (construct_command_argv_internal): OS/2 patches from
3123 Andreas Buening <andreas.buening@nexgo.de>.
3125 2004-05-10 Paul D. Smith <psmith@gnu.org>
3127 * remake.c (update_file): Don't walk the double-colon chain unless
3128 this is a double-colon rule. Fix suggested by Boris Kolpackov
3129 <boris@kolpackov.net>.
3131 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3132 * readme.vms: New section describing OpenVMS support and issues.
3133 * default.c (default_variables): Add support for IA64.
3134 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3135 without some privilege aborts make with the error
3136 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3137 pressing Ctrl+Y and the input device is no terminal. The change
3138 catches this error and just continues.
3140 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3142 2004-04-25 Paul D. Smith <psmith@gnu.org>
3144 * commands.c (set_file_variables): Set $< properly in the face of
3145 order-only prerequisites.
3146 Patch from Boris Kolpackov <boris@kolpackov.net>
3148 2004-04-21 Bob Byrnes <byrnes@curl.com>
3150 * main.c (main): Notice failures to remake makefiles.
3152 2004-03-28 Paul D. Smith <psmith@gnu.org>
3154 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3156 * job.c: No default shell for RISC OS.
3157 (load_too_high): Hard-code the return to 1.
3158 (construct_command_argv_internal): No sh_chars or sh_cmds.
3159 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3161 2004-03-20 Paul D. Smith <psmith@gnu.org>
3163 * variable.c (do_variable_definition): Don't append from the
3164 global set if a previous non-appending target-specific variable
3165 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3168 * expand.c (reference_variable): Don't give up on variables with
3169 no value that have the target-specific append flag set: they might
3170 have a value after all. Reported by Oliver Schmidt
3171 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3172 <nikulin@dx1cmd.inp.nsk.su>.
3174 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3175 refer to absolute pathnames in directories that don't exist: some
3176 portion of the makefile could create those directories before we
3177 match the pattern. Fixes bugs #775 and #108.
3179 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3181 * main.c (main): Free makefile_mtimes if we have any.
3182 * README.W32.template: Update documentation for the current status
3183 of the MS-Windows port.
3184 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3185 environment variable is sometimes already defined which causes the
3187 * main.c (debug_signal_handler): Only define this function if
3188 SIGUSR1 is available.
3190 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3192 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3193 * README.OS2.template: Documentation updates.
3194 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3195 link line for safety.
3196 * maintMakefile (build.sh.in): Remove an extraneous ")".
3197 * job.c (child_execute_job): Close saved FDs.
3198 * job.c (exec_command) [OS/2]: exec_command(): If the command
3199 can't be exec'ed and if the shell is not Unix-sh, then try again
3200 with argv = { "cmd", "/c", ... }. Normally, this code is never
3201 reached for the cmd shell unless the command really doesn't exist.
3202 (construct_command_argv_internal) [OS/2]: The code for cmd
3203 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3204 The CMD builtin commands are case insensitive so use strcasecmp().
3206 2004-03-19 Paul D. Smith <psmith@gnu.org>
3208 * read.c (do_define): Re-order line counter increment so the count
3209 is accurate (we were losing one line per define). Reported by
3210 Dave Yost <Dave@Yost.com>.
3212 2004-03-06 Paul D. Smith <psmith@gnu.org>
3214 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3216 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3217 * misc.c (message,error,fatal): Ditto.
3218 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3219 * config.h.W32.template: Ditto.
3220 * config.h-vms.template: Ditto.
3221 * config.ami.template: Ditto.
3223 2004-03-04 Paul D. Smith <psmith@gnu.org>
3225 * README.template: Add a note about broken /bin/sh on SunOS
3226 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3228 * misc.c (message, error, fatal): Don't use "..." if we're using
3229 varargs. ansi2knr should handle this but it doesn't work: it
3230 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3231 done. On many systems (SunOS for example) va_dcl is a #define.
3232 So, force the use of the non-"..." version on pre-ANSI compilers.
3234 * maintMakefile (sign-dist): Create some rules to help automate
3235 the new GNU ftp upload method.
3237 2004-02-24 Paul D. Smith <psmith@gnu.org>
3239 * config.h.W32.template: Add HAVE_STDARG_H
3240 * config.h-vms.template: Ditto.
3241 * config.ami.template: Ditto.
3243 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3245 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3246 * build_w32.bat: Remove extra "+".
3248 2004-02-23 Paul D. Smith <psmith@gnu.org>
3250 * make.h: Create an UNUSED macro to mark unused parameters.
3251 * (many): Clean up warnings by applying UNUSED, fixing
3252 signed/unsigned incompatibilities, etc.
3254 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3256 * filedef.h: Name the command_state enumeration.
3257 * file.c (set_command_state): Use the enumeration in the function
3260 * configure.in: Explicitly set SET_MAKE to empty, to disable
3261 MAKE=make even when no make already exists. Fix bug #3823.
3263 2004-02-22 Paul D. Smith <psmith@gnu.org>
3265 * maintMakefile: Perl script to clean up all non-CVS files. Use
3266 it on all the subdirectories for the cvs-clean target.
3268 * main.c (decode_switches): Require non-empty strings for all our
3269 string command-line options. Fixes Debian bug # 164165.
3271 * configure.in: Check for stdarg.h and varargs.h.
3272 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3273 for printing messages.
3274 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3279 A number of patches for OS/2 support from Andreas Buening
3280 <andreas.buening@nexgo.de>:
3282 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3283 disable the SIGCHLD handler.
3284 (reap_children) [OS/2]: Remove special handling of job_rfd.
3285 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3286 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3287 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3288 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3289 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3292 2004-02-21 Paul D. Smith <psmith@gnu.org>
3294 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3295 <mail@kristov.de> reports that if process_begin() fails we don't
3296 handle the error condition correctly in all cases.
3297 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3298 to have a newline on the message.
3300 * job.c (construct_command_argv_internal): Add "test" to UNIX
3301 sh_cmds[]. Fixes Savannah bug # 7606.
3303 2004-02-04 Paul D. Smith <psmith@gnu.org>
3305 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3306 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3307 Hartmut Becker <Hartmut.Becker@hp.com>.
3309 2004-01-21 Paul D. Smith <psmith@gnu.org>
3311 * job.c (load_too_high): Implement an algorithm to control the
3312 "thundering herd" problem when using -l to control job creation
3313 via the load average. The system only recomputes the load once a
3314 second but we can start many jobs in a second. To solve this we
3315 keep track of the number of jobs started in the last second and
3316 apply a weight to try to guess what a correct load would be.
3317 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3318 Also fixes bug #4693.
3319 (reap_children): Decrease the job count for this second.
3320 (start_job_command): Increase the job count for this second.
3322 * read.c (conditional_line): Expand the text after ifn?def before
3323 checking to see if it's a single word. Fixes bug #7257.
3325 2004-01-09 Paul D. Smith <psmith@gnu.org>
3327 * file.c (print_file): Recurse to print all targets in
3328 double-colon rules. Fixes bug #4518, reported (with patch) by
3329 Andrew Chatham <chatham@google.com>.
3331 2004-01-07 Paul D. Smith <psmith@gnu.org>
3333 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3334 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3335 AC_FUNC_SETVBUF_REVERSED.
3337 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3338 (MAKE Variable): Fix Savannah bug #4898.
3340 * job.c (construct_command_argv_internal): Add "!" to the list of
3341 shell escape chars. POSIX sh allows it to appear before a
3342 command, to negate the exit code. Fixes bug #6404.
3344 * implicit.c (pattern_search): When matching an implicit rule,
3345 remember which dependencies have the ignore_mtime flag set.
3346 Original fix provided in Savannah patch #2349, by Benoit
3347 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3349 2003-11-22 Paul D. Smith <psmith@gnu.org>
3351 * README.W32.template (Outputs): Clarification on -j with
3352 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3355 2003-11-02 Paul D. Smith <psmith@gnu.org>
3357 * function.c (func_if): Strip all the trailing whitespace from the
3358 condition, then don't expand it. Fixed bug # 5798.
3360 * expand.c (recursively_expand_for_file): If we're expanding a
3361 variable with no file context, then use the variable's context.
3364 2003-10-21 Paul D. Smith <psmith@gnu.org>
3366 * main.c (log_working_directory): Add newlines to printf()s.
3368 * README.cvs: Add a note to ignore warnings during autoreconf.
3370 * maintMakefile (po_repo): Set a new URL for PO file updates.
3371 (get-config/config.guess get-config/config.sub): Get these files
3372 from the Savannah config project instead of ftp.gnu.org.
3374 2003-10-05 Paul Eggert <eggert@twinsun.com>
3376 * main.c (main): Avoid potential subscript error if environ has
3379 2003-08-22 Paul D. Smith <psmith@gnu.org>
3381 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3382 systems which don't yet implement the C89 standard :-/.
3384 2003-07-18 Paul D. Smith <psmith@gnu.org>
3386 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3387 [WINDOWS32]: Initialize hash.
3389 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3391 * dir.c (read_dirstream): Provide a workaround for broken versions of
3392 the MinGW dirent structure.
3394 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3396 * w32/include/dirent.h: Add __MINGW32__ filter.
3398 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3400 * make.h: Add global declaration of *make_host.
3401 * main.c (print_usage): Remove local declaration of *make_host.
3402 (print_version): Display "This program built for ..." after Copyright
3405 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3407 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3408 execution of "makeinfo --html make.texi".
3410 2003-04-30 Paul D. Smith <psmith@gnu.org>
3412 * build.template: Make some changes to maybe allow this script to
3413 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3415 * README.OS2.template: New file for OS/2 support. Original
3416 contributed by Andreas Buening.
3417 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3420 2003-04-19 Paul D. Smith <psmith@gnu.org>
3422 Fix bug #1405: allow a target to match multiple pattern-specific
3425 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3426 variable.c, where they've always belonged.
3427 * rule.h: Move the prototypes and struct pattern_var as well.
3428 * variable.c (initialize_file_variables): Invoke
3429 lookup_pattern_var() in a loop, until no more matches are found.
3430 If a match is found, create a new variable set for the target's
3431 pattern variables. Then merge the contents of each matching
3432 pattern variable set into the target's pattern variable set.
3433 (lookup_pattern_var): Change this function to be usable
3434 in a loop. It takes a starting position: if NULL, start at the
3435 beginning; if non-NULL, start with the pattern variable after that
3436 position, and return the next matching pattern.
3437 (create_pattern_var): Create a unique instance of
3438 pattern-specific variables for every definition in the makefile.
3439 Don't combine the same pattern together. This allows us to
3440 process the variable handling properly even when the same pattern
3441 is used multiple times.
3442 (parse_variable_definition): New function: break out the parsing
3443 of a variable definition line from try_variable_definition.
3444 (try_variable_definition): Call parse_variable_definition to
3446 (print_variable_data_base): Print out pattern-specific variables.
3447 * variable.h (struct variable): Remember when a variable is
3448 conditional. Also remember its flavor.
3449 (struct pattern_var): Instead of keeping a variable set, we just
3450 keep a single variable for each pattern.
3451 * read.c (record_target_var): Each pattern variable contains only a
3452 single variable, not a set, so create it properly.
3453 * doc/make.texi (Pattern-specific): Document the new behavior.
3455 2003-04-17 Paul D. Smith <psmith@gnu.org>
3457 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3458 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3459 file/directory naming rules for VMS so I can't tell whether this
3462 2003-04-09 Paul D. Smith <psmith@gnu.org>
3464 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3465 DOS-style pathnames: backslash separators and drive specifiers.
3467 2003-03-28 Paul D. Smith <psmith@gnu.org>
3469 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3470 the intermediate flag on all targets. Fixes bug #2515.
3472 2003-03-24 Paul D. Smith <psmith@gnu.org>
3474 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3475 Upgrade to autoconf 2.57 and automake 1.7.3.
3477 * job.c: More OS/2 changes from Andreas Buening.
3479 * file.c (print_file): Fix variable initialization.
3482 * remake.c (notice_finished_file):
3484 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3485 some calls (like readdir()) return NULL in valid situations
3486 without resetting errno. Fixes bug #2846.
3488 2003-02-25 Paul D. Smith <psmith@gnu.org>
3490 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3492 * job.c (_is_unixy_shell) [OS/2]: New function.
3493 Set default shell to /bin/sh.
3494 (reap_children): Close the job_rfd pipe here since we don't use a
3496 (set_child_handler_action_flags): define this to empty on OS/2.
3497 (start_job_command): Close the jobserver pipe and use
3498 child_execute_job() instead of fork/exec.
3499 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3500 rather than exec'ing, then reconfigure stdin/stdout.
3501 (exec_command): Rewrite to use spawn instead of exec. Return the
3504 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3505 in DOS. Handle the TEMP environment variable as in DOS. Don't
3506 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3507 use -j in DOS mode. Use child_execute_job() instead of
3510 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3513 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3514 prototypes that return values.
3516 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3518 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3519 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3521 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3524 2003-02-24 Paul D. Smith <psmith@gnu.org>
3526 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3527 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3528 (child_execute_job) [VMS]: Handle error status properly.
3529 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3531 * function.c (func_shell): Use EINTRLOOP() while reading from the
3532 subshell pipe (Fixes bug #2502).
3533 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3535 * main.c (main): Ditto.
3537 2003-01-30 Paul D. Smith <psmith@gnu.org>
3539 * read.c (eval): eval() was not fully reentrant, because the
3540 collapsed buffer was static. Change it to be an automatic
3541 variable so that eval() can be invoked recursively.
3543 (eval): Apply patch # 1022: fix memory reference error on long
3544 target-specific variable lines.
3545 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3547 * function.c (check_numeric): Combine the is_numeric() function
3548 into this function, since it's only called from one place.
3549 Constify this function. Have it print the incorrect string in the
3550 error message. Fixes bug #2407.
3551 (strip_whitespace): Constify.
3552 (func_if): Constify.
3553 * expand.c (expand_argument): Constify.
3555 2003-01-29 Paul D. Smith <psmith@gnu.org>
3557 Fix bug # 2169, also reported by other people on various systems.
3559 * make.h: Some systems, such as Solaris and PTX, do not fully
3560 implement POSIX-compliant SA_RESTART functionality; important
3561 system calls like stat() and readdir() can still fail with EINTR
3562 even if SA_RESTART has been set on the signal handler. So,
3563 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3564 EINTR for system calls which return -1 or 0 (NULL), respectively,
3566 Also, remove the old atomic_stat()/atomic_readdir() and
3567 HAVE_BROKEN_RESTART handling.
3569 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3571 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3572 * remake.c (touch_file): Ditto.
3574 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3575 * read.c (construct_include_path): Ditto.
3576 * remake.c (name_mtime): Ditto.
3577 * vpath.c (selective_vpath_search): Ditto.
3578 * dir.c (find_directory): Ditto.
3579 (local_stat): Ditto.
3580 (find_directory): Use ENULLLOOP() to wrap opendir().
3581 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3583 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3584 atomic_readdir() handling.
3586 2003-01-22 Paul D. Smith <psmith@gnu.org>
3588 * function.c (func_call): Fix Bug #1744. If we're inside a
3589 recursive invocation of $(call ...), mask any of the outer
3590 invocation's arguments that aren't used by this one, so that this
3591 invocation doesn't "inherit" them accidentally.
3593 2002-12-05 Paul D. Smith <psmith@gnu.org>
3595 * function.c (subst_expand): Valery Khamenia reported a
3596 pathological performance hit when doing substitutions on very
3597 large values with lots of words: turns out we were invoking
3598 strlen() a ridiculous number of times. Instead of having each
3599 call to sindex() call strlen() again, keep track of how much of
3600 the text we've seen and pass the length to sindex().
3602 2002-11-19 Paul D. Smith <psmith@gnu.org>
3604 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3607 2002-11-16 Paul D. Smith <psmith@gnu.org>
3609 * NMakefile.template (OBJS): Add hash.c object file.
3610 * SMakefile.template (srcs): Ditto.
3611 * Makefile.ami (objs): Ditto.
3612 * build_w32.bat: Ditto.
3614 * Makefile.DOS.template: Remove extra dependencies.
3616 2002-10-25 Paul D. Smith <psmith@gnu.org>
3618 * expand.c (install_variable_buffer): New function. Install a new
3619 variable_buffer context and return the previous one.
3620 (restore_variable_buffer): New function. Free the current
3621 variable_buffer context and put a previously saved one back.
3622 * variable.h: Prototypes for {install,restore}_variable_buffer.
3623 * function.c (func_eval): Push a new variable_buffer context
3624 before we eval, then restore the old one when we're done.
3627 * read.c (install_conditionals): New function. Install a new
3628 conditional context and return the previous one.
3629 (restore_conditionals): New function. Free the current
3630 conditional context and put a previously saved one back.
3631 (eval): Use the {install,restore}_conditionals for "include"
3633 (eval_buffer): Use {install,restore}_conditionals to preserve the
3634 present conditional state before we evaluate the buffer.
3637 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3639 (Recursion): Add a variable index entry for CURDIR.
3641 * README.cvs: Update to appropriate versions.
3642 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3643 don't need to copy loadavg.c: automake is smart enough to create
3644 it for me. Still have a bug in automake related to ansi2knr tho.
3646 2002-10-14 Paul D. Smith <psmith@gnu.org>
3648 * remake.c (notice_finished_file): Only touch targets if they have
3649 at least one command (as per POSIX). Resolve Bug #1418.
3651 * *.c: Convert to using ANSI C-style function definitions.
3652 * Makefile.am: Enable the ansi2knr feature of automake.
3653 * configure.in: ditto.
3655 2002-10-13 Paul D. Smith <psmith@gnu.org>
3657 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3658 for automatic variable values like $^, etc. In the case of very
3659 large lists of prerequisites this causes problems. Instead reuse
3660 a static buffer (resizeable) for each variable.
3662 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3663 target-specific variable definitions. Check for it and set an
3665 (record_target_var): Set the export field to v_export if the
3666 "exported" flag is set.
3667 * doc/make.texi (Target-specific): Document the ability to use
3670 * doc/make.texi: Change the name of the section on automatic
3671 variables from "Automatic" to "Automatic Variables". Added text
3672 clarifying the scope of automatic variables.
3674 2002-10-04 Paul D. Smith <psmith@gnu.org>
3676 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3678 (record_files): Ditto.
3680 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3681 the search for the '=' to only within the enclosing parens.
3683 2002-10-03 Paul D. Smith <psmith@gnu.org>
3685 Version 3.80 released.
3687 * dir.c: Change hash functions to use K&R function definition style.
3688 * function.c: Ditto.
3690 * variable.c: Ditto.
3692 Update to automake 1.7.
3694 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3695 (pdf): Remove this target as automake now provides one.
3697 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3699 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3701 * makefile.com: Updates for GNU make 3.80.
3702 * makefile.vms: Ditto.
3704 2002-09-23 Paul D. Smith <psmith@gnu.org>
3706 * read.c (enum make_word_type): Remove w_comment.
3707 (get_next_mword): Don't treat comment characters as special; where
3708 this function is used we will never see a comment (it's stripped
3709 before we get here) and treating comments specially means that
3710 targets like "foo\#bar" aren't handled properly.
3712 2002-09-18 Paul D. Smith <psmith@gnu.org>
3714 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3716 * read.c (eval): Expansion of arguments to export/unexport was
3717 ignoring all arguments after the first one. Change the algorithm
3718 to expand the whole line once, then parse the results.
3720 2002-09-17 Paul D. Smith <psmith@gnu.org>
3722 Fix Bug #940 (plus another bug I found while looking at this):
3724 * read.c (record_target_var): enter_file() will add a new entry if
3725 it's a double-colon target: we don't want to do that in this
3726 situation. Invoke lookup_file() and only enter_file() if it does
3727 not already exist. If the file we get back is a double-colon then
3728 add this variable to the "root" double-colon target.
3730 * variable.c (initialize_file_variables): If this file is a
3731 double-colon target but is not the "root" target, then initialize
3732 the root and make the root's variable list the parent of our
3735 2002-09-13 Paul D. Smith <psmith@gnu.org>
3737 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3739 * hash.c (round_up_2): Get rid of a warning.
3741 2002-09-12 Paul D. Smith <psmith@gnu.org>
3743 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3744 so it doesn't complain about getloadavg.c.
3746 * commands.c (set_file_variables): Make sure we always alloca() at
3747 least 1 character for the value of $? (for '\0').
3749 2002-09-11 Paul D. Smith <psmith@gnu.org>
3751 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3752 macro to use RESULT instead of the incorrect _RESULT_.
3754 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3755 and atomic_readdir(). We need to #include dirent.h to get this to
3757 * misc.c (atomic_readdir): Fix typos.
3759 2002-09-10 Paul D. Smith <psmith@gnu.org>
3761 * read.c (eval): Expand variable lists given to export and
3762 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3763 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3765 * doc/make.texi (Variables/Recursion): Document this.
3766 (Conditional Syntax): And here.
3768 2002-09-09 Paul D. Smith <psmith@gnu.org>
3770 * configure.in: Check for memmove().
3772 2002-09-07 Paul D. Smith <psmith@gnu.org>
3774 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3775 Michael Sterrett <msterret@coat.com> reports that while it has
3776 SA_RESTART, it does not work properly.
3778 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3779 that invokes stat() and loops to do it again if it returns EINTR.
3780 (atomic_readdir): Ditto, with readdir().
3782 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3783 and readdir() to atomic_stat() and atomic_readdir().
3785 2002-09-04 Paul D. Smith <psmith@gnu.org>
3787 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3788 reports that GNU make sometimes doesn't recognize that targets can
3789 be made, when directories can be created as prerequisites. He
3790 reports that changing the order of predicates in the DEP->changed
3791 flag test so that lookup_file() is always performed, solves this
3794 2002-08-08 Paul D. Smith <psmith@gnu.org>
3796 * configure.in: Require a newer version of gettext.
3798 * misc.c (perror_with_name): Translate the format string (for
3799 right-to-left language support).
3800 (pfatal_with_name): Ditto.
3802 * main.c: Create a static array of strings to store the usage
3803 text. This is done to facilitate translations.
3804 (struct command_switch): Remove argdesc and description fields.
3805 (switches): Remove values for obsolete fields.
3806 (print_usage): Print each element of the usage array.
3808 * hash.c: Change function definitions to be K&R style.
3810 2002-08-02 Paul D. Smith <psmith@gnu.org>
3812 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3813 this one because it's too hard to get right. We'll look at it for
3815 * main.c (main): Don't create the .TARGETS variable.
3816 * variable.c (handle_special_var): Don't handle .TARGETS.
3818 2002-08-01 Paul D. Smith <psmith@gnu.org>
3820 * main.c (switches): Add a new option, -B (--always-make). If
3821 specified, make will rebuild all targets that it encounters even
3822 if they don't appear to be out of date.
3823 (always_make_flag): New flag.
3824 * make.h: Extern always_make_flag.
3825 * remake.c (update_file_1): Check always_make_flag; if it's set we
3826 will always rebuild any target we can, even if none of its
3827 prerequisites are newer.
3830 * doc/make.texi (Shell Function): Make it clear that make
3831 variables marked as "export" are not passed to instances of the
3834 Add new introspection variable .VARIABLES and .TARGETS.
3836 * variable.c (handle_special_var): New function. If the variable
3837 reference passed in is "special" (.VARIABLES or .TARGETS),
3838 calculate the new value if necessary. .VARIABLES is handled here:
3839 walk through the hash of defined variables and construct a value
3840 which is a list of the names. .TARGETS is handled by
3841 build_target_list().
3842 (lookup_variable): Invoke handle_special_var().
3843 * file.c (build_target_list): Walk through the hask of known files
3844 and construct a list of the names of all the ones marked as
3846 * main.c (main): Initialize them to empty (and as simple variables).
3847 * doc/make.texi (Special Variables): Document them.
3848 * NEWS: Mention them.
3850 * variable.h (struct variable): Add a new flag "exportable" which
3851 is true if the variable name is valid for export.
3852 * variable.c (define_variable_in_set): Set "exportable" when a new
3853 variable is defined.
3854 (target_environment): Use the "exportable" flag instead of
3855 re-checking the name here... an efficiency improvement.
3857 2002-07-31 Paul D. Smith <psmith@gnu.org>
3859 * config.h-vms.template: Updates to build on VMS. Thanks to
3860 Brian_Benning@aksteel.com for helping verify the build.
3861 * makefile.com: Build the new hash.c file.
3862 * hash.h: Use strcpmi(), not stricmp(), in the
3863 HAVE_CASE_INSENSITIVE_FS case.
3865 2002-07-30 Paul D. Smith <psmith@gnu.org>
3867 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3868 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3869 Reported by <Brian_Benning@aksteel.com>.
3871 2002-07-10 Paul D. Smith <psmith@gnu.org>
3873 * variable.c (pop_variable_scope): Remove variable made unused by
3874 new hash infrastructure.
3875 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3876 comparisons as well as name comparisons.
3877 * variable.h: Add a prototype for new hash_init_function_table().
3878 * file.c (lookup_file): Remove variables made unused by new hash
3880 * dir.c (directory_contents_hash_2): Missing return of hash value.
3881 (dir_contents_file_exists_p): Remove variables made unused by new
3882 hash infrastructure.
3885 Installed Greg McGary's integration of the hash functions from the
3886 GNU id-utils package:
3888 2002-07-10 Greg McGary <greg@mcgary.org>
3890 * scripts/functions/filter-out: Add literals to to the
3891 pattern space in order to add complexity, and trigger
3892 use of an internal hash table. Fix documentation strings.
3893 * scripts/targets/INTERMEDIATE: Reverse order of files
3894 passed to expected `rm' command.
3896 2002-07-10 Greg McGary <greg@mcgary.org>

3988 2002-07-10 Paul D. Smith <psmith@gnu.org>
3990 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3991 prerequisite list. A real SysV make will expand the entire
3992 prerequisites list _twice_: we don't do that as it's a big
3993 backward-compatibility problem. We only replace those specific
3996 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3997 references left in the list of prerequisites. Check for .POSIX as
3998 we record targets, so we can disable non-POSIX behavior while
3999 reading makefiles as well as running them.
4000 (eval): Check the prerequisite list to see if we have anything
4001 that looks like a SysV prerequisite variable reference.
4003 2002-07-09 Paul D. Smith <psmith@gnu.org>
4005 * doc/make.texi (Prerequisite Types): Add a new section describing
4006 order-only prerequisites.
4008 * read.c (uniquize_deps): If we have the same file as both a
4009 normal and order-only prereq, get rid of the order-only prereq,
4010 since the normal one supersedes it.
4012 2002-07-08 Paul D. Smith <psmith@gnu.org>
4014 * AUTHORS: Added Greg McGary to the AUTHORS file.
4015 * NEWS: Blurbed order-only prerequisites.
4016 * file.c (print_file): Show order-only deps properly when printing
4019 * maintMakefile: Add "update" targets for wget'ing the latest
4020 versions of various external files. Taken from Makefile.maint in
4023 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
4024 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
4026 2002-07-07 Paul D. Smith <psmith@gnu.org>
4028 * po/*.po: Remove. We'll use wget to retrieve them at release
4031 * variable.c (do_variable_definition) [W32]: On W32 using cmd
4032 rather than a shell you get an exception. Make sure we look up
4033 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
4035 * remake.c (notice_finished_file): Fix handling of -t flag.
4036 Patch provided by Henning Makholm <henning@makholm.net>.
4038 * implicit.c (pattern_search): Some systems apparently run short
4039 of stack space, and using alloca() in this function caused an
4040 overrun. I modified it to use xmalloc() on the two variables
4041 which seemed like they might get large. Fixes Bug #476.
4043 * main.c (print_version): Update copyright notice to conform with
4045 (print_usage): Update help output.
4047 * function.c (func_eval): Create a new make function, $(eval
4048 ...). Expand the arguments, put them into a buffer, then invoke
4049 eval_buffer() on the resulting string.
4050 (func_quote): Create a new function, $(quote VARNAME). Inserts
4051 the value of the variable VARNAME without expanding it any
4054 * read.c (struct ebuffer): Change the linebuffer structure to an
4055 "eval buffer", which can be either a file or a buffer.
4056 (eval_makefile): Move the code in the old read_makefile() which
4057 located a makefile into here: create a struct ebuffer with that
4058 information. Have it invoke the new function eval() with that
4060 (eval_buffer): Create a new function that creates a struct ebuffer
4061 that holds a string buffer instead of a file. Have it invoke
4062 eval() with that ebuffer.
4063 (eval): New function that contains the guts of the old
4064 read_makefile() function: this function parses makefiles. Obtains
4065 data to parse from the provided ebuffer. Some modifications to
4066 make the flow of the function cleaner and clearer. Still could
4067 use some work here...
4068 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
4069 contents of the define/endef variable from the ebuffer.
4070 (readstring): Read the next line from a string-style ebuffer.
4071 (readline): Read the next line from an ebuffer. If it's a string
4072 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
4075 * dep.h (eval_buffer): Prototype eval_buffer();
4077 * variable.c (do_variable_definition): Make sure that all
4078 non-target-specific variables are registered in the global set.
4079 If we're invoked from an $(eval ...) we might be inside a $(call
4080 ...) or other function which has pushed a variable scope; we still
4081 want to define our variables from evaluated makefile code in the
4084 2002-07-03 Greg McGary <greg@mcgary.org>
4086 * dep.h (struct dep) [ignore_mtime]: New member.

4091 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
4092 (read_makefile): Parse '|' in prerequisite list.
4093 (uniquize_deps): Consider ignore_mtime when comparing deps.
4094 * remake.c (update_file_1, check_dep): Don't force remake for
4095 dependencies that have d->ignore_mtime.
4096 * commands.c (FILE_LIST_SEPARATOR): New constant.
4097 (set_file_variables): Don't include a
4098 prerequisite in $+, $^ or $? if d->ignore_mtime.
4101 2002-06-18 Paul D. Smith <psmith@gnu.org>
4103 * make.texinfo: Updates for next revision. New date/rev/etc.
4104 Recreate all Info menus. Change license on the manual to the GNU
4105 Free Documentation License. A number of typos.
4106 (Variables Simplify): Don't use "-" before it's defined.
4107 (Automatic Prerequisites): Rewrite the target example to work
4108 properly if the compile fails. Remove incorrect comments about
4109 how "set -e" behaves.
4110 (Text Functions): Move the "word", "wordlist", "words", and
4111 "firstword" functions here, from "File Name Functions".
4112 * make-stds.texi: Update from latest GNU version.
4113 * fdl.texi: (created) Import the latest GNU version.
4115 2002-06-06 Paul D. Smith <psmith@gnu.org>
4117 * variable.c (do_variable_definition): New function: extract the
4118 part of try_variable_definition() that actually sets the value
4119 into a separate function.
4120 (try_variable_definition): Call do_variable_definition() after
4121 parsing the variable definition string.
4122 (define_variable_in_set): Make the name argument const.
4124 * variable.h (enum variable_flavor): Make public.
4125 (do_variable_definition): Create prototype.
4127 * read.c (read_all_makefiles): Create a new built-in variable,
4129 (read_makefile): Add each makefile read in to this variable value.
4131 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4133 * Makefile.DOS.template: Tweak according to changes in the
4134 distribution. Add back the dependencies of *.o files.
4136 * configh.dos.template: Synchronize with config.h.in.
4138 2002-05-09 Paul D. Smith <psmith@gnu.org>
4140 * file.c (file_timestamp_now): Use K&R function declaration.
4142 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4143 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4144 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4145 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4146 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4147 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4148 nlist.n_name is a pointer rather than an array.
4150 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4151 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4152 * configure.in: Use it instead of the old version.
4154 * main.c (main): Prefer setvbuf() to setlinebuf().
4156 2002-05-08 Paul D. Smith <psmith@gnu.org>
4158 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4159 (loadavg_LDADD): Ditto.
4161 2002-04-29 Paul D. Smith <psmith@gnu.org>
4163 * expand.c (recursively_expand_for_file): Rename
4164 recursively_expand() to recursively_expand_for_file() and provide
4165 an extra argument, struct file. If the argument is provided, set
4166 the variable scope to that of the file before expanding.
4167 * variable.h (recursively_expand): Make this a macro that invokes
4168 recursively_expand_for_file() with a NULL file pointer.
4169 * variable.c (target_environment): Call the renamed function and
4170 provide the current file context.
4171 Fixes Debian bug #144306.
4173 2002-04-28 Paul D. Smith <psmith@gnu.org>
4175 Allow $(call ...) user-defined variables to be self-referencing
4176 without throwing an error. Allows implementation of transitive
4177 closures, among other possibly useful things.
4178 Requested by: Philip Guenther <guenther@sendmail.com>
4180 * variable.h (struct variable): Add a new field: exp_count, and
4181 new macros to hold its size and maximum value.
4182 (warn_undefined): Make this a macro.
4183 * variable.c (define_variable_in_set): Initialize it.
4184 * expand.c (recursively_expand): If we detect recursive expansion
4185 of a variable, check the exp_count field. If it's greater than 0
4186 allow the recursion and decrement the count.
4187 (warn_undefined): Remove this (now a macro in variable.h).
4188 * function.c (func_call): Before we expand the user-defined
4189 function, modify its exp_count field to contain the maximum
4190 number of recursive calls we'll allow. After the call, reset it
4193 2002-04-21 Paul D. Smith <psmith@gnu.org>
4195 Modified to use latest autoconf (2.53), automake (1.6.1), and
4196 gettext (0.11.1). We're using gettext's new "external" support,
4197 to avoid including libintl source with GNU make.
4199 * README.cvs: New file. Explain how to build GNU make from CVS.
4201 * configure.in: Modify checking for the system glob library.
4202 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4203 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4204 etc. will manage it correctly). Set an automake conditional
4205 USE_LOCAL_GLOB to decide whether to compile the glob library.
4207 * getloadavg.c (main): Include make.h in the "TEST" program to
4210 * Makefile.am: Remove special rules for loadavg. Replace them
4211 with Automake capabilities for building extra programs.
4213 * signame.c: This file does nothing if the system provide
4214 strsignal(). If not, it implements strsignal(). If the system
4215 doesn't define sys_siglist, then we make our own; otherwise we use
4217 * signame.h: Removed.
4219 * main.c (main): No need to invoke signame_init(). Update copyright.
4221 * ABOUT-NLS: Removed.
4222 * gettext.c: Removed.
4223 * gettext.h: Get a simplified copy from the gettext package.
4225 * i18n/*.po: Moved to po/.
4228 * config/*: Created. Contains package configuration helper files.
4229 * config.guess, config.sub: Moved to config directory.
4231 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4232 Rework to use new-style autoconf features. Use the "external"
4233 mode for gettext. Make the build.sh config file conditional on
4234 whether build.sh.in exists, to avoid autoconf errors.
4235 * acinclude.m4: Removed almost all macros as being obsolete.
4236 Rewrote remaining macros to use AC_DEFINE.
4237 * acconfig.h: Removed.
4239 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4240 conditional to handle customs support. Remove special handling
4243 2002-04-20 Paul D. Smith <psmith@gnu.org>
4245 * function.c (func_call): Don't mark the argument variables $1,
4246 etc. as recursive. They've already been fully expanded so
4247 there's no need to do it again, and doing so strips escaped $'s.
4248 Reported by Sebastian Glita <glseba@yahoo.com>.
4250 * remake.c (notice_finished_file): Walk through double-colon
4251 entries via the prev field, not the next field!
4252 Reported by Greg McGary <greg@mcgary.org>.
4254 * main.c (main): If the user specifies -q and asks for a specific
4255 target which is a makefile, we got an assert. In that case it
4256 turns out we should continue normally instead.
4258 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4260 * i18n/he.po: Installed a new translation.
4262 2002-01-07 Paul D. Smith <psmith@gnu.org>
4264 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4266 2001-12-04 Paul D. Smith <psmith@gnu.org>
4268 * i18n/ja.po: Installed an updated translation.
4270 2001-09-06 Paul Eggert <eggert@twinsun.com>
4272 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4273 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4275 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4277 (main): Get rid of any avoidable limit on stack size.
4279 2001-09-04 Paul D. Smith <psmith@gnu.org>
4281 * i18n/da.po: Installed an updated translation.
4283 2001-08-03 Paul D. Smith <psmith@gnu.org>
4285 * i18n/fr.po: Installed an updated translation.
4286 Resolves Debian bug #106720.
4288 2001-06-13 Paul D. Smith <psmith@gnu.org>
4290 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4293 2001-06-11 Paul D. Smith <psmith@gnu.org>
4295 * i18n/ko.po: Installed a new translation.
4297 2001-05-06 Paul D. Smith <psmith@gnu.org>
4299 Modify the EINTR handling.
4301 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4302 the way in which we manage the file descriptor/signal handler race
4303 trap to be more efficient.
4305 2001-05-06 Paul Eggert <eggert@twinsun.com>
4307 Restart almost all system calls that are interrupted, instead
4308 of worrying about EINTR. The lone exception is the read() for
4311 * configure.in (HAVE_SA_RESTART): New macro.
4312 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4313 * main.c (main): Use SA_RESTART instead of the old,
4314 nonstandard SA_INTERRUPT.
4316 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4317 * main.c (bsd_signal): New function or macro,
4318 if the implementation doesn't supply it.
4319 (The bsd_signal function will be in POSIX 1003.1-200x.)
4320 (HANDLESIG): Remove.
4321 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4323 * make.h (EINTR_SET): Remove.
4324 (SA_RESTART): New macro.
4326 * arscan.c (ar_member_touch): Don't worry about EINTR.
4327 * function.c (func_shell): Likewise.
4328 * job.c (reap_children, free_child, new_job): Likewise.
4329 * main.c (main): Likewise.
4330 * remake.c (touch_file, name_mtime): Likewise.
4332 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4333 if fstat failed with errno!=EINTR, the error was ignored.
4335 * job.c (set_child_handler_action_flags): New function.
4336 (new_job): Use it to temporarily clear the SIGCHLD action flags
4337 while reading the token.
4339 2001-05-02 Paul D. Smith <psmith@gnu.org>
4341 * job.c (start_job_command): Don't add define/endef per-line flags
4342 to the top-level flags setting.
4344 2001-04-03 Paul D. Smith <psmith@gnu.org>
4346 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4347 bit on error, so check for odd return values, not non-0 return
4349 (VMS_get_member_info): Calculate the timezone differences correctly.
4350 Reported by John Fowler <jfowler@nyx.net>.
4353 2001-03-14 Paul D. Smith <psmith@gnu.org>
4355 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4356 value before invoking define_variable().
4357 Reported by John Fowler <jfowler@nyx.net>.
4359 2001-02-07 Paul D. Smith <psmith@gnu.org>
4361 * read.c (record_target_var): If we reset the variable due to a
4362 command-line variable setting overriding it, turn off the "append"
4365 2001-01-17 Paul D. Smith <psmith@gnu.org>
4367 * variable.c (lookup_variable) [VMS]: When getting values from the
4368 environment, allocate enough space for the _value_ plus escapes,
4369 not enough space for the name plus escapes :-/.
4370 Reported by John Fowler <jfowler@nyx.net>.
4372 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4373 warnings that make generates, so it doesn't look like an error.
4374 Reported by Karl Berry <karl@gnu.org>.
4377 Fix for PR/2020: Rework appended target-specific variables. I'm
4378 fairly confident this algorithm is finally correct.
4380 * expand.c (allocated_variable_append): Rewrite. Instead of
4381 expanding each appended variable then adding all the expanded
4382 strings together, we append all the unexpanded values going up
4383 through the variable set contexts, then expand the final result.
4384 This behaves just like non-target-specific appended variable
4385 values, while the old way didn't in various corner cases.
4386 (variable_append): New function: recursively append the unexpanded
4387 value of a variable, walking from the outermost variable scope to
4389 * variable.c (lookup_variable): Remove the code that looked up the
4390 variable set list if the found variable was "append". We don't
4392 (lookup_variable_in_set): Make this non-static so we can use it
4394 (try_variable_definition): Use lookup_variable_in_set() rather
4395 than faking out current_variable_set_list by hand (cleanup).
4396 * variable.h: Add a prototype for the now non-static
4397 lookup_variable_in_set().
4399 2000-11-17 Paul D. Smith <psmith@gnu.org>
4401 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4402 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4403 before throwing a fit.
4405 2000-11-17 Paul D. Smith <psmith@gnu.org>
4407 * read.c (readline): CRLF calculations had a hole, if you hit the
4408 buffer grow scenario just right. Reworked the algorithm to avoid
4409 the need for len or lastlen at all. Problem description with
4410 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4412 2000-10-24 Paul D. Smith <psmith@gnu.org>
4414 * gettext.c (SWAP): Declare this with the prototype, otherwise
4415 some systems don't work (non-32-bit? Reported for Cray T3E).
4416 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4418 2000-10-05 Paul D. Smith <psmith@gnu.org>
4420 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4421 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4423 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4425 2000-09-22 Paul D. Smith <psmith@gnu.org>
4427 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4428 parts of the real gettext.h here, and we expect to really include
4429 the real gettext.h later. If we keep this #define, it's ignored.
4431 2000-09-21 Paul D. Smith <psmith@gnu.org>
4433 * main.c (log_working_directory): Rework the text to use complete
4434 sentences, to make life simpler for the translators.
4436 2000-08-29 Paul D. Smith <psmith@gnu.org>
4438 * file.c (remove_intermediates): Print a debug message before we
4439 remove intermediate files, so the user (if she uses -d) knows
4442 2000-08-21 Paul D. Smith <psmith@gnu.org>
4444 * variable.c (try_variable_definition): Change how we handle
4445 target-specific append variable defns: instead of just setting the
4446 value, expand it as an append _but_ only within the current
4447 target's context. Otherwise we lose all but the last value if the
4448 variable is appended more than once within the current target
4449 context. Fixes PR/1831.
4451 2000-08-16 Paul D. Smith <psmith@gnu.org>
4453 * function.c (func_shell): Nul-terminate the buffer before
4454 printing an exec error message (just in case it's not!).
4455 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4457 2000-07-25 Paul D. Smith <psmith@gnu.org>
4459 * job.c (construct_command_argv_internal): Add "~" to the list of
4460 sh_chars[] which disallow optimizing out the shell call.
4462 2000-07-23 Paul Eggert <eggert@twinsun.com>
4464 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4465 supersedes --disable-nsec-timestamps.
4466 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4467 * README: Remove --disable-nsec-timestamps.
4469 * filedef.h (struct file.low_resolution_time): New member.
4470 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4471 * remake.c (update_file_1):
4472 Avoid spurious rebuilds due to low resolution time stamps,
4473 generalizing the earlier code that applied only to archive members.
4474 (f_mtime): Archive members always have low resolution time stamps.
4476 * configure.in: Remove --disable-nsec-timestamps, as this has
4477 been superseded by .LOW_RESOLUTION_TIME.
4479 2000-07-23 Paul Eggert <eggert@twinsun.com>
4481 * configure.in (enable_nsec_timestamps): Renamed from
4482 make_cv_nsec_timestamps, since enable/disable options
4483 shouldn't be cached.
4485 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4486 and Paul Eggert <eggert@twinsun.com>
4488 * file.c (file_timestamp_now):
4489 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4490 so that clock_gettime is not linked unless needed.
4492 * filedef.h (FILE_TIMESTAMP_HI_RES):
4493 Remove definition; "configure" now does this.
4495 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4496 to before high resolution file timestamp check,
4497 since that check now uses uintmax_t.
4498 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4499 high resolution file timestamps.
4500 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4501 so that we don't link in clock_gettime unnecessarily.
4503 2000-07-17 Paul D. Smith <psmith@gnu.org>
4505 * i18n/ja.po: New version of the translation file.
4507 2000-07-07 Paul D. Smith <psmith@gnu.org>
4509 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4510 the offset calculation.
4511 (name_mtime): Replace EINTR test with EINTR_SET macro.
4513 2000-07-07 Paul Eggert <eggert@twinsun.com>
4517 * remake.c (update_file_1):
4518 Avoid spurious rebuilds of archive members due to their
4519 timestamp resolution being only one second.
4520 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4521 the clock's resolution being lower than file timestamps'.
4522 When warning about future timestamps, report only the discrepancy,
4523 not the absolute value of the timestamp and the current time.
4525 * file.c (file_timestamp_now): New arg RESOLUTION.
4526 * filedef.h (file_timestamp_now): Likewise.
4527 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4529 2000-07-05 Paul D. Smith <psmith@gnu.org>
4531 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4532 to listp. Fixes PR/1793.
4534 2000-06-26 Paul Eggert <eggert@twinsun.com>
4536 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4538 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4540 * remake.c (f_mtime): Remove unused var memtime.
4542 2000-06-25 Martin Buchholz <martin@xemacs.org>
4544 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4545 Ran spell-check on make.texinfo.
4547 2000-06-23 Paul D. Smith <psmith@gnu.org>
4549 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4550 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4551 * make.h: Define these macros.
4553 * Version 3.79.1 released.
4555 * configure.in: Add a new option, --disable-nsec-timestamps, to
4556 avoid using sub-second timestamps on systems that support it. It
4557 can lead to problems, e.g. if your makefile relies on "cp -p".
4558 * README.template: Document the issue with "cp -p".
4560 * config.guess, config.sub: Updated.
