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

713 2010-07-01 Paul Smith <psmith@gnu.org>
715 * main.c (main): Append optional features using separate calls.

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

777 lowest directory index.
779 * implicit.c (pattern_search): Pass NULL for the index arguments in
780 the VPATH_SEARCH call.
782 * doc/make.texi (Directory Search for Link Libraries): Describe the

841 (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.
843 * commands.c (set_file_variables): Avoid modifying the dep
844 chain to achieve uniqueness. Fixes savannah bug 25780.

870 if we need to parse a rule that requires the second expansion.
872 2009-10-03 Paul Smith <psmith@gnu.org>
874 * make.h: Include <alloca.h> even on systems where __GNUC__ is
875 defined. Not sure why it was done the other way.
876 Requested by David Boyce <dsb@boyski.com>.
878 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>
880 * dep.h (dep): Add the DONTCARE bitfield.
882 * filedef.h (file):Add the NO_DIAG bitfield.
884 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
885 not struct file (a file can be a dependency of many targets,

888 * remake.c (update_goal_chain): Propagate DONTCARE from struct
889 dep to struct file before updating the goal and restore it

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

934 double-colons have a different meaning. Savannah bug #27497.
936 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
938 * configh.dos.template: Remove unconditional definition of
939 SYS_SIGLIST_DECLARED.
940 Include <sys/version.h> because ports of GCC 4.3.0 and later no
941 longer include it, so macros like __DJGPP_MINOR__ are no longer
942 defined automatically.
944 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
945 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
946 instead of using the hardcoded ones.
947 (SUBDIRS): doc subdir added.
948 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
949 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
950 create html formated docs. texi2html may not be ported to DOS.
951 (make.info, make.dvi, make.ps, make.html): Make targets depend on
953 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
954 -I switch to look in ./ instead of ./doc.
955 (html): Target depend on html-recursive instead of make_1.html.
956 (make_1.html): Removed.
957 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
958 (all-recursive): Allow for more than one subdir in the build
960 (mostlyclean-recursive, clean-recursive, distclean-recursive)
961 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
962 (tags-recursive): Allow for more than one subdir in the build
964 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
965 targets. Enter into doc/ to produce the targets.
966 (all-am): $(INFO_DEPS) replaced by info.
968 2009-09-26 Paul Smith <psmith@gnu.org>
970 * read.c (record_files): Use free_ns() to free struct nameseq.
973 * rule.c (freerule): Use free_dep_chain().
975 * read.c (record_files): Free FILENAMES chain for implicit rules.
976 (eval): Static pattern targets go into the string cache.
978 * function.c (string_glob): Free NAME in the nameseq chain.
980 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
982 * implicit.c (pattern_search): Terminate early if we haven't
983 found any rules to try (performance improvement).
985 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
987 * implicit.c (pattern_search): Merge three parallel arrays,
988 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
989 of struct TRYRULE. In the old version the latter two arrays
990 had insufficient length.
992 2009-09-24 Paul Smith <psmith@gnu.org>
994 * implicit.c (pattern_search): Add back support for order-only
995 prerequisites for secondary expansion implicit rules, that were
996 accidentally dropped. If we find a "|", enable order-only mode
997 and set IGNORE_MTIME on all deps that are seen afterward.
998 (pattern_search): Fix memory leaks: for intermediate files where
999 we've already set the file variable and pattern variable sets, be
1000 sure to either save or free them as appropriate.
1002 2009-09-23 Paul Smith <psmith@gnu.org>
1004 Rework the way secondary expansion is stored, for efficiency.
1005 This changes secondary expansion so that ONLY WHEN we know we have
1006 a possibility of needing secondary expansion, do we defer the
1007 secondary expansion. This means more parsing the deps but we use
1008 a lot less memory (due to the strcache). Also, this fixes
1009 Savannah bug #18622.
1011 * read.c (eval): Don't parse the dep string here anymore.
1012 (record_files): Take the dep argument as an unparsed string. If
1013 secondary expansion is enabled AND the prereq string has a '$' in
1014 it, then set NEED_2ND_EXPANSION and keep the entire string.
1015 Otherwise, parse the dep string here to construct the dep list
1016 with the names in the strcache.
1018 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
1019 duplicate the name string (others are in the strcache).
1021 * implicit.c: Remove struct idep and free_idep_chain(): unused.
1022 (struct patdeps): New structure to store prereq information.
1023 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
1024 which prerequisites need expansion, and expand only those.
1026 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
1027 and enter_prereqs(). split_prereqs() takes a fully-expanded string
1028 and splits it into a DEP list, handling order-only prereqs.
1029 (enter_prereqs): This function enters a list of DEPs into the file
1030 database. If there's a stem defined, expand any pattern chars.
1031 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
1032 set. Use the above functions.
1033 (snap_deps): Only perform second expansion on prereqs that need it,
1034 as defined by the NEED_2ND_EXPANSION flag.
1035 (print_prereqs): New function to print the prereqs
1036 (print_file): Call print_prereqs() rather than print inline.
1038 * hash.h (STRING_COMPARE): Take advantage of strcache() by
1040 (STRING_N_COMPARE): Ditto.
1041 (ISTRING_COMPARE): Ditto.
1043 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
1044 (parse_file_seq): Return void*
1045 * read.c (parse_file_seq): Return void*.
1046 (eval): Invoke macroized version of parse_file_seq()
1047 * default.c (set_default_suffixes): Ditto.
1048 * file.c (split_prereqs): Ditto.
1049 * function.c (string_glob): Ditto.
1050 * main.c (main): Ditto.
1051 * rule.c (install_pattern_rule): Ditto.
1053 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
1055 2009-09-16 Paul Smith <psmith@gnu.org>
1057 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
1059 * dep.h: Create alloc_dep() / free_dep() macros.
1061 * implicit.c (pattern_search): Take advantage of the new
1062 parse_file_seq() to add the directory prefix to each prereq.
1064 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
1065 all. Avoid reversing chains. Support adding prefixes.
1066 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
1067 cached/non-cached results.
1068 (eval): Remove multi_glob() & invoke new parse_file_seq().
1069 * rule.c (install_pattern_rule): Ditto.
1070 * main.c (main): Ditto.
1071 * implicit.c (pattern_search): Ditto.
1072 * function.c (string_glob): Ditto.
1073 * file.c (parse_prereqs): Ditto.
1074 * default.c (set_default_suffixes): Ditto.
1076 * variable.c (parse_variable_definition): Don't run off the end of
1077 the string if it ends in whitespace (found with valgrind).
1079 * commands.c (set_file_variables): Keep space for all targets in
1080 $? if -B is given (found with valgrind).
1082 2009-09-15 Paul Smith <psmith@gnu.org>
1084 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
1085 (xcalloc): Add new function.
1086 * make.h: New declarations.
1088 * ar.c (ar_glob_match): New calling method for concat().
1089 * main.c (main): Ditto.
1090 (decode_env_switches): Ditto.
1091 * read.c (eval_makefile): Ditto.
1092 (tilde_expand): Ditto.

1094 * variable.c (target_environment): Ditto.
1095 (sync_Path_environment): Ditto.
1097 * ar.c (ar_glob_match): Use xcalloc().
1098 * dir.c (file_impossible): Ditto.
1099 * file.c (enter_file): Ditto.
1100 * job.c (new_job): Ditto.
1101 * read.c (parse_file_seq): Ditto.
1102 * vmsfunctions.c (opendir): Ditto.
1104 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
1106 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
1107 inside the loop that looks up environment for PATH.
1109 2009-08-31 Eli Zaretskii <eliz@gnu.org>
1111 * function.c (windows32_openpipe): Update envp after calling
1112 sync_Path_environment.
1114 2009-08-02 Paul Smith <psmith@gnu.org>
1116 * remake.c (notice_finished_file): Ensure file->cmds is not null
1117 before looping through them. Fixes Savannah bug #21824.
1119 * doc/make.texi (Wildcard Examples): Clarify when objects is
1120 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1121 (Include): Clarify the behavior of -include.
1122 Fixes Savannah bug #18963.
1124 2009-08-01 Paul Smith <psmith@gnu.org>
1126 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1127 etc. come on the command line. Fixes Savannah bug #27093.
1129 * expand.c (expand_argument): If the argument is large enough use
1130 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1132 * variable.c (do_variable_definition): Avoid using alloca() to
1133 hold values, which can be large. Fixes Savannah bug #23960.
1135 * job.c (new_job): Use memmove() instead of strcpy() since both
1136 pointers are in the same memory block. Fixes Savannah bug #27148.
1137 Patch by Petr Machata.
1139 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1141 * job.c (construct_command_argv_internal): Add "ulimit" and
1142 "unset" to the sh_cmds for Unixy shells.
1144 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1146 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1147 that set make_cv_sys_gnu_glob, so they are also correctly set
1148 when the cache has been populated before.
1150 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1152 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1153 exist, as realpath(3) does where it's supported.
1155 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1157 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1158 (abspath): Support systems that define HAVE_DOS_PATHS (have
1159 drive letters in their file names). Use IS_PATHSEP instead of a
1160 literal '/' comparison. Fixes Savannah bug #26886.
1162 2009-06-14 Paul Smith <psmith@gnu.org>
1164 * remake.c (update_file_1): Remember the original file we marked
1165 as updating, so we can clear that flag again. If we find a target
1166 via vpath, FILE might change.
1167 (check_dep): Ditto. Fixes Savannah bug #13529.
1168 Patch by Reid Madsen <reid.madsen@tek.com>.
1170 2009-06-13 Paul Smith <psmith@gnu.org>
1172 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1173 included by MAKEFILES cannot give default goals.
1174 * read.c (eval): If set_default is not set, pass the no-default-goal
1175 value when we read included makefiles. Fixes Savannah bug #13401.
1177 * ar.c (ar_name): Ensure that targets with empty parens aren't
1178 considered archive member references: archive members must have a
1179 non-empty "member" string. Fixes Savannah bug #18435.
1181 * function.c (string_glob): Rely on multi_glob() to determine
1182 whether files exist or not. Remove call to file_exists_p() which
1183 is not always correct. Fixes Savannah bug #21231.
1184 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1185 then only files that really exist will be returned.
1186 * dep.h: Add new argument to multi_glob().
1187 * rule.c (install_pattern_rule): Ditto.
1188 * read.c (eval): Ditto.
1189 * main.c (main): Ditto.
1190 * implicit.c (pattern_search): Ditto.
1191 * file.c (parse_prereqs): Ditto.
1192 * default.c (set_default_suffixes): Ditto.
1194 2009-06-09 Paul Smith <psmith@gnu.org>
1196 * commands.c (set_file_variables): If always_make_flag is set,
1197 always add the prereq to $?. Fixes Savannah bug #17825.
1199 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1200 to rebuild the deps of all the also_make targets for that file.
1201 Fixes Savannah bug #19108.
1203 * implicit.c (pattern_search): Undo test for is_target, added by
1204 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1205 Rule Search Algorithm". Fixes Savannah bug #17752.
1207 * main.c (clean_jobserver): Clear the jobserver_fds options and
1208 set job_slots to the default when we clean up.
1209 (define_makeflags): Return the new MAKEFLAGS value.
1210 (main): Reset MAKEFLAGS in the environment when we re-exec.
1211 Fixes Savannah bug #18124.
1213 2009-06-08 Paul Smith <psmith@gnu.org>
1215 * read.c (eval): Collapse continuations post-semicolon on target-
1216 specific variables. Fixes Savannah bug #17521.
1218 2009-06-07 Paul Smith <psmith@gnu.org>
1220 * job.c (reap_children): For older systems without waitpid() (are
1221 there any of these left?) run wait(2) inside EINTRLOOP to handle
1222 EINTR errors. Fixes Savannah bug #16401.
1224 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1226 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1228 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1229 not the end, to catch second expansion $(eval ...) defining new
1230 target/prereq relationships during snap_deps.
1231 Fixes Savannah bug #24622.
1233 * read.c (record_files): The second-expansion "f->updating" hack
1234 was not completely correct: if assumed that the target with
1235 commands always had prerequisites; if one didn't then the ordering
1236 was messed up. Fixed for now to use f->updating to decide whether
1237 to preserve the last element in the deps list... but this whole
1238 area of constructing and reversing the deps list is too confusing
1239 and needs to be reworked. Fixes Savannah bug #21198.
1241 2009-06-06 Paul Smith <psmith@gnu.org>
1243 * hash.c (hash_insert): Remove useless test for NULL.
1244 Fixes Savannah bug #21823.
1246 * make.h: Move SET_STACK_SIZE determination to make.h.
1247 * main.c (main): New global variable, STACK_LIMIT, holds the
1248 original stack limit when make was started.
1249 * job.c (start_job_command): Reset the stack limit, if we changed it.
1250 Fixes Savannah bug #22010.
1252 * remake.c (check_dep): Only set the target's state to not-started
1253 if it's not already running. Found this while testing -j10 builds
1254 of glibc: various targets were being rebuilt multiple times.
1255 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1258 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1259 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1262 2009-06-04 Paul Smith <psmith@gnu.org>
1264 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1266 * maintMakefile: Modify access of config and gnulib Savannah
1267 modules to use GIT instead of CVS.
1269 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1270 Fixes Savannah bug #24655.
1272 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1273 this can happen during some invocations of $(eval ...) for example.
1274 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1276 2009-06-02 Paul Smith <psmith@gnu.org>
1278 * configure.in: Check for fileno()
1279 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1280 for the makefile file so invocations of $(shell ...) don't inherit it.
1281 Fixes Savannah bug #24277.
1283 2009-06-01 Paul Smith <psmith@gnu.org>
1285 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1286 expansion was handled incorrectly. Rework the default goal
1287 handling to save the variable only. Remove default_goal_file and
1289 * read.c (eval): Check default_goal_var, not default_goal_name.
1290 * read.c (record_target_var): Don't check default_goal_file here.
1292 2009-05-31 Paul Smith <psmith@gnu.org>
1294 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1295 it, and if the multi_glob() returns nothing (say it expanded to
1296 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1298 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1299 $(and ..) to the reference. Fixes Savannah bug #25694.
1301 * make.1: Be clear that some recipes will be executed even with -n.
1302 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1304 * doc/make.texi (Override Directive): Make more clear how
1305 overrides and appends interact.
1306 Elucidates part of Savannah bug #26207.
1308 * read.c (record_target_var): Don't reset the origin on
1309 target-specific variables; try_variable_definition() will handle
1310 this correctly. Fixes Savannah bug #26207.
1312 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1313 Fixes Savannah bug #25712.
1315 * implicit.c (pattern_search): Keep a pointer to the beginning of
1316 the filename and save that instead of the constructed pointer.
1317 Fixes Savannah bug #26593.
1318 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1320 2009-05-30 Paul Smith <psmith@gnu.org>
1322 * doc/make.texi (Multi-Line): Add a description of the new abilities
1323 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1324 "command sequence" vs. "recipe" syntax.
1325 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1326 after a define, to create variables with those flavors.
1328 2009-05-25 Paul Smith <psmith@gnu.org>
1330 Reworked the parser for variable assignments to allow multiple
1331 modifiers, and in any order. Also allows variable and
1332 prerequisites to be modifier names ('export', 'private', etc.)
1334 * NEWS: Add notes about user-visible changes.
1336 * read.c (struct vmodifiers): Remember what modifiers were seen.
1337 (parse_var_assignment): New function to parse variable assignments.
1338 (eval): Call the new function. Handle variable assignments earlier.
1340 * variable.c (parse_variable_definition): Only parse; don't create var.
1341 (assign_variable_definition): Call parse, then create the var.
1343 2009-05-24 Paul Smith <psmith@gnu.org>
1345 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1346 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1348 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1350 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1351 Fixes Savannah bug #25412.
1353 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1354 prototype for xmalloc.
1355 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1356 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1357 Loop over an array of extensions, instead of duplicating the same
1358 code inline. Use SearchPath followed by CreateFile, instead of
1359 the obsolete OpenFile. Fixes Savannah bug #17277.
1360 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1361 to `find_file'. Fixes Savannah bug #25662.
1363 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1365 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1366 Fixes Savannah bug #20495.
1368 2009-02-28 Ralf Wildenhues <address@hidden>
1370 * doc/make.texi (Instead of Execution): Document interaction of
1371 -t with phony targets.
1373 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1375 Introduce a new keyword "private" which applies to target-specific
1376 variables and prevents their values from being inherited.
1378 * variable.h (struct variable): Add private_var flag to each variable.
1379 Add a flag to specify which list entry switches to the parent target.
1380 * variable.c (define_variable_in_set): Initialize private_var flag.

1393 * make.h: Rename savestring to xstrndup.
1394 * commands.c (chop_commands): Ditto.
1395 * function.c (func_foreach): Ditto.
1396 * read.c (eval, record_files): Ditto.
1397 * variable.c (define_variable_in_set): Ditto.
1399 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1401 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1404 * w32/subproc/build.bat (GCCBuild): Likewise.
1406 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1408 * job.c (construct_command_argv_internal): Avoid extra backslash
1409 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1412 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1414 * README.W32.template: Remove obsolete text about non-support for
1415 -jN without Unixy shell. Remove obsolete text about not supplying
1416 Visual Studio project files (we do supply them). Modify text to
1417 prefer GCC builds to MSC builds.
1419 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1421 * doc/make.texi (Empty Targets): Fix typo.
1423 2008-03-27 Paul Smith <psmith@gnu.org>

1436 `value' field is NULL.
1438 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1440 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1442 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1443 (TEXINFOS): Value changed to `doc/make.texi'.
1444 (.SUFFIXES): Use .texi instead of .texinfo.
1445 (make.info, make.dvi): Depend on doc/make.texi.
1446 (.texi.info): New target, instead of ".texinfo.info". Change -I
1447 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1448 (.texi): New target, instead of ".texinfo". Change -I switch to
1449 $(MAKEINFO) to look in doc/. Use --no-split.
1450 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1451 switch to $(MAKEINFO) to look in doc/.
1452 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1453 "*.i[0-9][0-9]" (due to --no-split above).
1454 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1455 (html, make_1.html): New targets.
1456 (.PHONY): Add "html".

1462 HAVE_DECL_SYS_SIGLIST.
1464 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1465 build does not use child_execute_job.
1467 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1468 export the SHELL environment variable to the child.
1470 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1472 * config.h.W32: Include sys/types.h.
1473 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1475 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH

1489 * remake.c (f_mtime): Print time difference values between 100 and
1490 ULONG_MAX in fixed-point notation rather than in exponention notation.
1492 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1494 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1495 a more complex value than a simple shell: if it's not a default
1496 shell now then expand it and see if is a default shell then.
1498 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1500 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1501 pathnames, with const strings.
1502 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1503 from the template (used for building from CVS, not a dist).
1505 2007-10-10 Paul Smith <psmith@gnu.org>
1507 * make.h: Add a prototype for w32_kill() (change suggested by
1508 Yongwei Wu <wuyongwei@gmail.com>).
1510 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1512 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1513 directories in Path.
1515 2007-09-12 Paul Smith <psmith@gnu.org>
1517 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
1518 Provided by Diego Biurrun <diego@biurrun.de>
1519 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1520 Provided by Diego Biurrun <diego@biurrun.de>
1522 2007-09-11 Paul Smith <psmith@gnu.org>
1524 * doc/make.texi (Special Variables): Moved this into the "How to
1525 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1526 (MAKEFILE_LIST) No longer a section; this was added into the
1527 "Special Variables" section.
1528 (Rule Introduction): Reference .RECIPEPREFIX.
1529 (Simple Makefile): Ditto.
1530 (Rule Syntax): Ditto.
1531 (Command Syntax): Ditto.
1532 (Error Messages): Ditto.
1534 2007-09-10 Paul Smith <psmith@gnu.org>
1536 * commands.c (print_commands): Don't print an extra line in the
1537 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1539 * read.c (construct_include_path): Add the full string to the cache; we
1540 were chopping the last char.
1542 * NEWS: Announce the .RECIPEPREFIX special variable.
1543 * variable.c (lookup_special_var): Rename from handle_special_var().
1544 (lookup_variable): Call the new name.
1545 (set_special_var): New function: handle setting of special variables.
1546 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1547 (do_variable_definition): Call it.
1548 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1549 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1550 * main.c (main): Create the .RECIPEPREFIX special variable.
1551 * read.c (eval): Remove the cmd_prefix characters from the command
1552 scripts here, so they're not stored in the commands array at all,
1553 rather than waiting and stripping them out during command construction.
1554 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1556 2007-08-15 Paul Smith <psmith@gnu.org>
1558 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1559 file has had the section info removed, so add some to make.texi
1560 before we include it.
1562 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1564 * remake.c (check_dep): Reset the target state for intermediate
1565 files. They might have been considered before but not updated

1572 * function.c (func_shell): Call construct_command_argv with zero
1574 * job.c (construct_command_argv_internal): New argument FLAGS; all

1580 2007-07-13 Paul Smith <psmith@gnu.org>
1582 * file.c (expand_deps): Use variable_buffer as the start of the
1583 buffer, not the original pointer (in case it was reallocated).
1584 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1585 Fixes Savannah bug #20452.

1600 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1601 "Expansion of a deferred"
1602 Fixes Savannah bug #20018.
1604 * expand.c (variable_expand_for_file): Preserve the value of
1605 reading_file rather than setting it to 0 at the end.
1606 Fixes Savannah bug #20033.
1608 2007-05-11 Paul Smith <psmith@gnu.org>
1610 * job.c (new_job): Add debug info to specify where make found the
1611 command script it is running to build a target.

1622 Dave Korn <dave.korn@artimi.com>
1624 2007-05-08 Paul Smith <psmith@gnu.org>
1626 Fix Savannah bug #19656:
1628 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1630 * make.h: Change all case-insensitive string compares to use
1631 strcasecmp() (from POSIX). If we don't have that but do have one
1632 of the others, define strcasecmp to be one of those instead. If
1633 we don't have any, declare a prototype for our own version.
1635 * misc.c (strcasecmp): Use this if we can't find any native
1636 case-insensitive string comparison function.
1637 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1638 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1640 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1641 strcasecmp() instead of stricmp().
1642 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1643 instead of strcmpi().
1644 * acinclude.m4: Remove the strcasecmp() check from here.
1646 2007-03-21 Paul Smith <psmith@gnu.org>
1648 * configure.in: Don't turn on case-insensitive file system support
1649 if --disable-... is given. Fixes Savannah bug #19348.
1651 2007-03-19 Paul Smith <psmith@gnu.org>
1653 * ALL: Use the strcache for all file name strings, or other
1654 strings which we will never free. The goal is to save memory by
1655 avoiding duplicate copies of strings. However, at the moment this
1656 doesn't save much memory in most situations: due to secondary
1657 expansion we actually save prerequisite lists twice (once before
1658 the secondary expansion, and then again after it's been parsed
1659 into individual file names in the dep list). We will resolve this
1660 in a future change, by doing the parsing up-front for targets
1661 where secondary expansion is not set.
1663 Moving things into the strcache also allows us to use const
1664 pointers in many more places.
1666 2007-01-03 Paul Smith <psmith@gnu.org>
1668 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1669 the function, not just the first. Fixes Savannah bug #18680.
1671 2006-11-18 Paul Smith <psmith@gnu.org>
1673 * strcache.c (strcache_add_len): Don't allocate a new buffer
1674 unless the string is not already nil-terminated. Technically this
1675 is a violation of the standard, since we may be passed an array
1676 that is not long enough to test one past. However, in make this
1677 is never true since we only use nil-terminated strings or
1678 sub-strings thereof.
1680 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1682 * main.c: New global cmd_prefix, defaults to '\t'.
1683 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1686 * dir.c: Constified.
1687 (dir_contents_file_exists_p): Check for an error return from
1688 readdir(), just in case.
1690 * commands.c: Constified.
1691 * default.c: Constified.
1692 * expand.c: Constified.
1693 * function.c: Partial constification.

1698 * w32/pathstuff.c: Partial constification.
1700 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1702 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1703 backslashes and drive letters as absolute.
1705 2006-10-22 Paul Smith <psmith@gnu.org>
1707 * main.c (struct command_switch): Use const and void*.
1709 2006-10-21 Paul Smith <psmith@gnu.org>
1712 * arscan.c: Constified.
1714 2006-09-30 Paul Smith <psmith@gnu.org>
1716 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1717 point to lastword since the example was updated.
1718 Fixes Savannah bug #16304.
1719 (Secondary Expansion): Correct example description.
1720 Fixes Savannah bug #16468.
1721 (Makefile Contents): Clarify that comments cannot appear within
1722 variable references or function calls.
1723 Fixes Savannah bug #16577.
1724 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1725 Fixes Savannah bug #17701.
1726 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1728 prerequisites. Fixes Savannah bug #17880.
1729 (Rule Syntax): "lise" -> "list"
1730 (Multiple Rules): ... -> @dots{}
1731 (Splitting Lines): ditto.
1733 * remake.c (update_file_1): Prereqs that don't exist should be
1734 considered changed, for the purposes of $?.
1735 Fixes Savannah bug #16051.
1737 * make.1: Remove extraneous "+".

1777 that don't have extended grep.
1778 (cvsclean): Use $(PERL) instead of perl.

1782 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1784 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1785 inner-scope variables don't mask outer-scope variables.
1787 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

1790 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned

1846 Declare and define sh_chars_sh[].
1848 2006-03-23 Paul D. Smith <psmith@gnu.org>
1850 * configure.in: Look for build.sh.in in $srcdir so it will be
1851 built for remote configurations as well.
1853 * Makefile.am: Make sure to clean up build.sh during distclean.
1854 Fixes Savannah bug #16166.
1856 * misc.c (log_access): Takes a const char *.

1862 * implicit.c (pattern_search): Call set_file_variables only
1863 if we have prerequisites that need second expansion. Fixes
1864 Savannah bug #16140.

1872 make sure I don't forget any).
1874 * main.c (clean_jobserver): Move jobserver cleanup code into a new

1885 Patch from Joseph Myers <joseph@codesourcery.com>
1887 2006-03-17 Boris Kolpackov <boris@kolpackov.net>

1890 * misc.c (alloc_dep, free_dep): New functions.
1891 (copy_dep_chain): Copy stem.
1892 (free_dep_chain): Use free_dep.
1893 * read.c (record_files): Store stem in the dependency line.
1894 * file.c (expand_deps): Use stem stored in the dependency line. Use

1908 Fixes Savannah bug #15913.
1910 2006-03-09 Paul Smith <psmith@gnu.org>
1912 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1913 listed non-existent files as changed. Turns out there's a bug in
1914 the Linux kernel builds which means that this change causes
1915 everything to rebuild every time. We will re-introduce this fix
1916 in the next release, to give them time to fix their build system.
1917 Fixes Savannah bug #16002.
1918 Introduces Savannah bug #16051.
1920 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1935 2006-02-19 Paul D. Smith <psmith@gnu.org>
1937 * commands.c (set_file_variables): Realloc, not malloc, the static
1938 string values to avoid memory leaks.
1940 * expand.c (recursively_expand_for_file): Only set reading_file to
1941 an initialized value.
1943 * implicit.c (pattern_search): We need to make a copy of the stem
1944 if we get it from an intermediate dep, since those get freed.
1946 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1948 (enter_file) [VMS]: Ditto.
1949 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

1953 * job.c (construct_command_argv_internal): Fix last change.
1955 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1956 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1957 the calls to _beginthreadex.
1959 * expand.c (recursively_expand_for_file): Initialize `save' to
1960 prevent compiler warnings.
1962 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1964 * job.c (construct_command_argv_internal): Don't create a temporary
1965 script/batch file if we are under -n. Call _setmode to switch the
1966 script file stream to text mode.

1970 * variable.c (merge_variable_set_lists): Don't try to merge the
1971 global_setlist. Not only is this useless, but it can lead to
1972 circularities in the linked list, if global_setlist->next in one
1973 list gets set to point to another list which also ends in
1975 Fixes Savannah bug #15757.
1977 2006-02-15 Paul D. Smith <psmith@gnu.org>
1979 Fix for Savannah bug #106.
1981 * expand.c (expanding_var): Keep track of which variable we're
1982 expanding. If no variable is being expanded, it's the same as
1984 * make.h (expanding_var): Declare it.
1985 * expand.c (recursively_expand_for_file): Set expanding_var to the
1986 current variable we're expanding, unless there's no file info in
1987 it (could happen if it comes from the command line or a default
1988 variable). Restore it before we exit.

2000 * read.c (eval): Even if the included filenames expands to the
2001 empty string we still need to free the allocated buffer.
2003 * implicit.c (pattern_search): If we allocated a variable set for
2004 an impossible file, free it.
2005 * variable.c (free_variable_set): New function.
2006 * variable.h: Declare it.
2008 * read.c (read_all_makefiles): Makefile names are kept in the
2009 strcache, so there's never any need to alloc/free them.
2012 * main.c (main): Add "archives" to the .FEATURES variable if
2013 archive support is enabled.
2014 * doc/make.texi (Special Variables): Document it.
2016 2006-02-13 Paul D. Smith <psmith@gnu.org>

2024 * (ALL FILES): Updated copyright and license notices.
2026 2006-02-10 Paul D. Smith <psmith@gnu.org>
2028 A new internal capability: the string cache is a read-only cache
2029 of strings, with a hash table interface for fast lookup. Nothing
2030 in the cache will ever be freed, so there's no need for reference
2031 counting, etc. This is the beginning of a full solution for
2032 Savannah bug #15182, but for now we only store makefile names here.
2034 * strcache.c: New file. Implement a read-only string cache.
2035 * make.h: Add prototypes for new functions.
2036 * main.c (initialize_global_hash_tables): Initialize the string cache.
2037 (print_data_base): Print string cache stats.
2038 * read.c (eval_makefile): Use the string cache to store makefile
2039 names. Rewrite the string allocation to be sure we free everything.
2041 2006-02-10 Eli Zaretskii <eliz@gnu.org>
2043 * dir.c (dir_contents_file_exists_p): Don't opendir if the
2044 directory time stamp didn't change, except on FAT filesystems.

2067 timestamp from -o or -W, use that instead of the real time.
2068 * remake.c (f_mtime): If the mtime is a special token from -o or
2069 -W, don't overwrite it with the real mtime.

2075 (process_signal, process_last_err, process_exit_code): Manage
2076 invalid handle values.
2077 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
2078 manage invalid handles; remove them.

2080 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
2081 * README.cvs: Updates for building from CVS.
2083 2006-02-05 Paul D. Smith <psmith@gnu.org>

2086 to avoid walking the list every time we want to add a new one.
2087 Fixes Savannah bug #15533.
2088 * filedef.h (struct file): Add a new LAST pointer.
2090 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
2091 the comparison. For 64-bits systems the result of the subtraction
2092 might not fit into an int. Use comparison instead.
2093 Fixes Savannah bug #15534.
2095 * doc/make.texi: Update the chapter on writing commands to reflect
2096 the changes made in 3.81 for backslash/newline and SHELL handling.
2098 2006-02-01 Paul D. Smith <psmith@gnu.org>
2100 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
2101 variable st is not used when it's not initialized.
2102 Patch from Eli Zaretskii <eliz@gnu.org>.
2104 2006-01-31 Paul D. Smith <psmith@gnu.org>
2106 * README.W32.template: Applied patch #4785 from
2107 Markus Mauhart <qwe123@chello.at>.
2108 * README.cvs: Applied patch #4786 from
2109 Markus Mauhart <qwe123@chello.at>.

2114 * prepare_w32.bat: Remove this file from the distribution.
2116 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2118 * remake.c (update_goal_chain): Set g->changed instead of
2119 incrementing it, as it is only 8-bit wide, and could overflow if
2120 many commands got started in update_file.
2122 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
2124 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
2125 MAXIMUM_WAIT_OBJECTS.
2126 (process_wait_for_any_private): Change dimension of handles[]
2127 array to MAXIMUM_WAIT_OBJECTS.
2128 (process_used_slots): New function.
2129 (process_register): Don't register more processes than the
2130 available number of slots.
2131 (process_easy): Don't start new processes if all slots are used up.
2133 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
2134 are already more children than sub_proc.c can handle, behave as if
2135 the load were too high.
2136 (start_job_command): Fix a typo in error message when process_easy
2139 2006-01-14 Eli Zaretskii <eliz@gnu.org>
2141 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
2142 the shell is not sh.exe.
2144 * job.c (create_batch_file): Renamed from create_batch_filename;
2145 all callers changed. Don't close the temporary file; return its
2146 file descriptor instead. New arg FD allows to return the file
2148 (construct_command_argv_internal): Use _fdopen instead of fopen to
2149 open the batch file.
2151 2006-01-04 Paul D. Smith <psmith@gnu.org>
2153 * readme.vms: Updates for case-insensitive VMS file systems from
2154 Hartmut Becker <Hartmut.Becker@hp.com>.
2155 * dir.c (vms_hash): Ditto.
2156 * vmsify.c (copyto): Ditto.
2157 * vmsfunctions.c (readdir): Ditto.
2159 * make.1: Add a section on the exit codes for make.
2161 * doc/make.texi: A number of minor updates to the documentation.
2163 2006-01-03 Paul D. Smith <psmith@gnu.org>
2165 * remake.c (update_file_1): Mark a prerequisite changed if it
2168 * read.c (eval): Be sure to strip off trailing whitespace from the
2169 prerequisites list properly. Also, initialize all fields in
2170 struct dep when creating a new one.
2172 2005-12-28 Paul D. Smith <psmith@gnu.org>
2174 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2175 disable warnings for MSC.
2176 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2178 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2180 * doc/make.texi (Execution): Add a footnote about changes in
2181 handling of backslash-newline sequences. Mention the differences
2182 on MS-DOS and MS-Windows.
2184 * NEWS: More details about building the MinGW port and a pointer
2185 to README.W32. Fix the section name that describes the new
2186 backward-incompatible processing of backslash-newline sequences.
2187 The special processing of SHELL set to "cmd" is only relevant to
2188 MS-Windows, not MS-DOS.
2190 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2192 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2193 to DWORD, to avoid compiler warnings.
2194 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2195 use %ld in format, to avoid compiler warnings.
2197 * doc/make.texi (Special Targets): Fix a typo.
2198 (Appending): Fix cross-reference to Setting.
2199 (Special Variables, Secondary Expansion, File Name Functions)
2200 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2201 periods after a sentence.
2202 (Execution): Add @: after "e.g.".
2203 (Environment): Fix punctuation.
2204 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2205 (Shell Function, Target-specific): Add @: after "vs."
2207 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2209 * read.c (record_target_var): Initialize variable's export field
2210 with v_default instead of leaving it "initialized" by whatever
2211 garbage happened to be on the heap.
2213 2005-12-12 Paul D. Smith <psmith@gnu.org>
2215 * make.1: Fix some display errors and document all existing options.
2216 Patch by Mike Frysinger <vapier@gentoo.org>.
2218 2005-12-11 Paul D. Smith <psmith@gnu.org>
2220 * implicit.c (pattern_search): If 2nd expansion is not set for
2221 this implicit rule, replace the pattern with the stem directly,
2222 and don't re-expand the variable list. Along with the other
2223 .SECONDEXPANSION changes below, fixes bug #13781.
2225 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2227 * implicit.c (pattern_search): Mark other files that this rule
2228 builds as targets so that they are not treated as intermediates
2229 by the pattern rule search algorithm. Fixes bug #13022.
2231 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2233 * remake.c (notice_finished_file): Propagate the change of
2234 modification time to all the double-colon entries only if
2235 it is the last one to be updated. Fixes bug #14334.
2237 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2239 * function.c (func_flavor): Implement the flavor function which
2240 returns the flavor of a variable.
2241 * doc/make.texi (Functions for Transforming Text): Document it.
2242 * NEWS: Add it to the list of new functions.
2244 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2246 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2248 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2249 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2251 2005-10-26 Paul Smith <psmith@gnu.org>
2253 * read.c (record_files): Don't set deps flags if there are no deps.
2254 * maintMakefile: We only need to build the templates when we are
2255 creating a distribution, so don't do it for "all".
2257 2005-10-24 Paul D. Smith <psmith@gnu.org>
2259 Make secondary expansion optional: its enabled by declaring the
2260 special target .SECONDEXPANSION.
2262 * NEWS: Update information on second expansion capabilities.
2263 * doc/make.texi (Secondary Expansion): Document the
2264 .SECONDEXPANSION special target and its behavior.
2265 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2266 prerequisite list was found in a static pattern rule.
2267 (free_dep_chain): Declare a prototype.
2268 * file.c (parse_prereqs): New function: break out some complexity
2270 (expand_deps): If we aren't doing second expansion, replace % with
2271 the stem for static pattern rules. Call the new function.
2272 * filedef.h (parse_prereqs): Declare a prototype.
2273 * implicit.c (pattern_search): Initialize the new staticpattern
2275 * main.c (second_expansion): Declare a global variable to remember
2276 if the special target has been seen. Initialize the new
2277 staticpattern field for prerequisites.
2278 * make.h: Extern for second_expansion.
2279 * misc.c (free_dep_chain): New function: frees a struct dep list.
2280 * read.c (read_all_makefiles): Initialize the staticpattern field.
2281 (eval_makefile): Ditto.
2282 (record_files): Check for the .SECONDEXPANSION target and set
2283 second_expansion global if it's found.
2284 Use the new free_dep_chain() instead of doing it by hand.
2285 Set the staticpattern field for prereqs of static pattern targets.
2287 2005-10-16 Paul D. Smith <psmith@gnu.org>
2289 * main.c (main): Set CURDIR to be a file variable instead of a
2290 default, so that values of CURDIR inherited from the environment
2291 won't override the make value.
2293 2005-09-26 Paul D. Smith <psmith@gnu.org>
2295 * job.c (construct_command_argv_internal): If the line is empty
2296 remember to free the temporary argv strings.
2299 2005-09-16 Paul D. Smith <psmith@gnu.org>
2301 * job.c (start_job_command): The noerror flag is a boolean (single
2302 bit); set it appropriately.
2303 Reported by Mark Eichin <eichin@metacarta.com>
2305 2005-08-29 Paul D. Smith <psmith@gnu.org>
2307 * function.c (func_error): On Windows, output from $(info ...)
2308 seems to come in the wrong order. Try to force it with fflush().
2310 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2312 * read.c (record_files): Move code that sets stem for static
2313 pattern rules out of the if (!two_colon) condition so it is
2314 also executed for two-colon rules. Fixes Savannah bug #13881.
2316 2005-08-08 Paul D. Smith <psmith@gnu.org>
2318 * make.h: Don't test that __STDC__ is non-0. Some compilers
2319 (Windows for example) set it to 0 to denote "ISO C + extensions".
2322 2005-08-07 Paul D. Smith <psmith@gnu.org>
2324 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2325 conditional (slightly different version of a fix from Eli).
2327 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2328 If make is running in parallel without -k and two jobs die in a
2329 row, but not too close to each other, then make will quit without
2330 waiting for the rest of the jobs to die.
2332 * main.c (die): Don't reset err before calling reap_children() the
2333 second time: we still want it to be in the error condition.
2334 * job.c (reap_children): Use a static variable, rather than err,
2335 to control whether or not the error message should be printed.
2337 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2339 * w32/subproc/sub_proc.c: Include signal.h.
2340 (process_pipe_io, process_file_io): Pass a pointer to a local
2341 DWORD variable to GetExitCodeProcess. If the exit code is
2342 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2344 * job.c [WINDOWS32]: Include windows.h.
2345 (main_thread) [WINDOWS32]: New global variable.
2346 (reap_children) [WINDOWS32]: Get the handle for the main thread
2347 and store it in main_thread.
2349 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2350 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2351 doing anything else. When we are done, close the main thread
2352 handle and exit with status 130.
2354 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2356 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2359 * main.c (find_and_set_default_shell): If found a DOSish shell,
2360 set sh_found and the value of default_shell, and report the
2361 findings in debug mode.
2363 * job.c (construct_command_argv_internal): Check unixy_shell, not
2364 no_default_sh_exe, to decide whether to use Unixy or DOSish
2367 * README.W32: Update with info about the MinGW build.
2369 * build_w32.bat: Support MinGW.
2371 * w32/subproc/build.bat: Likewise.
2373 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2374 printing DWORD args.
2376 * function.c (windows32_openpipe): Fix format strings for printing
2379 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2381 (start_job_command): Fix format string for printing the result of
2383 (start_job_command) [WINDOWS32]: Do not define.
2384 (exec_command): Fix format string for printing HANDLE args.
2386 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2387 to avoid compiler warnings.
2388 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2389 (Note: some of these fixes were submitted independently by J. Grant)
2391 2005-07-30 J. Grant <jg@jguk.org>
2393 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2394 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2395 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2397 2005-07-15 Paul Smith <psmith@gnu.org>
2399 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2400 we don't have a POSIX shell, then revert to the old
2401 backslash-newline behavior (where they are stripped).
2404 2005-07-08 Paul D. Smith <psmith@gnu.org>
2406 * config.h.W32.template: Reorder to match the standard config.h,
2407 for easier comparisons.
2408 From J. Grant <jg@jguk.org>
2410 * maintMakefile: Remove .dep_segment before overwriting it, in
2411 case it's not writable or noclobber is set.
2412 * expand.c (variable_expand_string): Cast result of pointer
2413 arithmetic to avoid a warning.
2414 * main.c (switches): Add full-fledged final initializer.
2416 2005-07-06 Paul D. Smith <psmith@gnu.org>
2418 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2419 * signame.c (strsignal): If we found _sys_siglist[] or
2420 __sys_siglist[] use those instead of sys_siglist[].
2421 From Albert Chin <china@thewrittenword.com>
2423 2005-07-04 Paul D. Smith <psmith@gnu.org>
2425 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2426 globfree(); set up to use the GNU versions.
2427 From Martin Zinser <zinser@zinser.no-ip.info>
2429 2005-07-03 Paul D. Smith <psmith@gnu.org>
2431 From J. Grant <jg@jguk.org>:
2433 * README.W32.template: Update the Windows and tested MSVC versions.
2434 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2435 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2436 * build_w32.bat: Ditto.
2437 * w32/subproc/build.bat: Ditto.
2439 2005-06-28 Paul D. Smith <psmith@gnu.org>
2441 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2442 declaration was checked but not present.
2444 2005-06-27 Paul D. Smith <psmith@gnu.org>
2446 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2447 to unsigned long. Fixes Savannah bug #13550.
2449 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2450 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2451 Fixes Savannah bug #13551.
2453 2005-06-26 Paul D. Smith <psmith@gnu.org>
2455 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2456 it if ANSI_STRING is not set.
2458 2005-06-25 Paul D. Smith <psmith@gnu.org>
2460 * read.c (eval): If no filenames are passed to any of the
2461 "include" variants, don't print an error.
2462 * doc/make.texi (Include): Document this.
2463 Fixes Savannah bug #1761.
2465 * job.c (construct_command_argv_internal): Sanitize handling of
2466 backslash/newline pairs according to POSIX: that is, keep the
2467 backslash-newline in the command script, but remove a following
2468 TAB character, if present. In the fast path, make sure that the
2469 behavior matches what the shell would do both inside and outside
2470 of quotes. In the slow path, quote the backslash and put a
2471 literal newline in the string.
2472 Fixes Savannah bug #1332.
2473 * doc/make.texi (Execution): Document the new behavior and give
2475 * NEWS: Make a note of the new behavior.
2477 * make.h [WINDOWS32]: #include <direct.h>.
2478 Fixes Savannah bug #13478.
2480 * remake.c (name_mtime): If the stat() of a file fails and the -L
2481 option was given and the file is a symlink, take the best mtime of
2482 the symlink we can get as the mtime of the file and don't fail.
2483 Fixes Savannah bug #13280.
2485 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2486 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2487 inside a variable reference. Make this function static as it's
2489 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2490 parsing an unexpanded line looking for semicolons.
2491 Fixes Savannah bug #1454.
2492 * misc.c (remove_comments): Move this to read.c and make it static
2493 as it's only used there. Call find_char_unquote() with new arg.
2494 * make.h: Remove prototypes for find_char_unquote() and
2495 remove_comments() since they're static now.
2497 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2498 its export flag and obtain its value. When we need to re-exec,
2499 increment the value and add it into the environment.
2500 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2501 * NEWS: Mention MAKE_RESTARTS.
2502 * main.c (always_make_set): New variable. Change the -B option to
2503 set this one instead.
2504 (main): When checking makefiles, only set always_make_flag if
2505 always_make_set is set AND the restarts flag is 0. When building
2506 normal targets, set it IFF always_make_set is set.
2507 (main): Avoid infinite recursion with -W, too: only set what-if
2508 files to NEW before we check makefiles if we've never restarted
2509 before. If we have restarted, set what-if files to NEW _after_ we
2511 Fixes Savannah bug #7566:
2513 2005-06-17 Paul D. Smith <psmith@gnu.org>
2515 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2516 in the prerequisites list.
2518 2005-06-12 Paul D. Smith <psmith@gnu.org>
2520 Fix Savannah bug # 1328.
2522 * configure.in: Check for atexit().
2523 * misc.c (close_stdout): Test stdout to see if writes to it have
2524 failed. If so, be sure to exit with a non-0 error code. Based on
2525 code found in gnulib.
2526 * make.h: Prototype.
2527 * main.c (main): Install close_stdout() with atexit().
2529 2005-06-10 Paul D. Smith <psmith@gnu.org>
2531 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2533 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2534 headers; make vmsWaitForChildren() static; extern vmsify().
2535 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2536 Don't create child_execute_job() here (it's in vmsjobs.c).
2537 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2539 2005-06-09 Paul D. Smith <psmith@gnu.org>
2541 * variable.c (push_new_variable_scope): File variables point
2542 directly to the global_setlist variable. So, inserting a new
2543 scope in front of that has no effect on those variables: they
2544 don't go through current_variable_set_list. If we're pushing a
2545 scope and the current scope is global, push it "the other way" so
2546 that the new setlist is in the global_setlist variable, and
2547 next points to a new setlist with the global variable set.
2548 (pop_variable_scope): Properly undo a push with the new
2550 Fixes Savannah bug #11913.
2552 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2554 * job.c (reap_children): Don't die of the command failed but
2555 the dontcare flag is set. Fixes Savannah bug #13216.
2557 * implicit.c (pattern_search): When creating a target from
2558 an implicit rule match, lookup pattern target and set precious
2559 flag in a newly created target. Fixes Savannah bug #13218.
2561 2005-05-13 Paul D. Smith <psmith@gnu.org>
2563 Implement "if... else if... endif" syntax.
2565 * read.c (eval): Push all checks for conditional words ("ifeq",
2566 "else", etc.) down into the conditional_line() function.
2567 (conditional_line): Rework to allow "else if..." clause. New
2568 return value -2 for lines which are not conditionals. The
2569 ignoring flag can now also be 2, which means "already parsed a
2570 true branch". If that value is seen no other branch of this
2571 conditional can be considered true. In the else parsing if there
2572 is extra text after the else, invoke conditional_line()
2573 recursively to see if it's another conditional. If not, it's an
2574 error. If so, raise the conditional value to this level instead
2575 of creating a new conditional nesting level. Special check for
2576 "else" and "endif", which aren't allowed on the "else" line.
2577 * doc/make.texi (Conditional Syntax): Document the new syntax.
2579 2005-05-09 Paul D. Smith <psmith@gnu.org>
2581 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2582 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2583 recurses to the w32 directory, even on non-Windows systems. Use
2584 the method suggested in the automake manual.
2585 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2586 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2588 2005-05-07 Paul D. Smith <psmith@gnu.org>
2590 * main.c (die): If we're dying with a fatal error (not that a
2591 command has failed), write back any leftover tokens before we go.
2593 * job.c (set_child_handler_action_flags): If there are jobs
2594 waiting for the load to go down, set an alarm to go off in 1
2595 second. This allows us to wake up from a potentially long-lasting
2596 read() and start a new job if the load has gone down. Turn it off
2598 (job_noop): Dummy signal handler function.
2599 (new_job): Invoke it with the new semantics.
2601 * docs/make.texi: Document secondary expansion. Various cleanups
2604 2005-05-03 Paul D. Smith <psmith@gnu.org>
2606 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2607 the targets which are to ultimately be made are called "goals";
2608 see the GNU make manual. Also, MAKECMDGOALS, etc.
2610 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2611 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2612 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2614 2005-05-02 Paul D. Smith <psmith@gnu.org>
2616 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2617 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2618 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2619 functions to vmsjobs.c. #include it into jobs.c.
2621 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2622 jobserver tokens. I found that this happens when an exported
2623 recursive variable contains a $(shell ...) function reference: in
2624 this situation we could "forget" to write back a token.
2626 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2627 we have. It's not reliable to depend on the number of children in
2628 our linked list so keep a separate count.
2629 (new_job): Check jobserver_tokens rather than children &&
2630 waiting_jobs. Increment jobserver_tokens when we get one.
2631 (free_child): If jobserver_tokens is 0, internal error. If it's
2632 >1, write a token back to the jobserver pipe (we don't write a
2633 token for the "free" job). Decrement jobserver_tokens.
2635 * main.c: Add variable master_job_slots.
2636 (main): Set it to hold the number of jobs requested if we're the
2637 master process, when using the jobserver.
2638 (die): Sanity checks: first test jobserver_tokens to make sure
2639 this process isn't holding any tokens we didn't write back.
2640 Second, if master_job_slots is set count the tokens left in the
2641 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2643 2005-04-24 Paul D. Smith <psmith@gnu.org>
2645 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2646 with -l# can lose jobserver tokens, because waiting jobs are not
2647 consulted properly when checking for the "free" token.
2649 * job.c (free_child): Count waiting_jobs as having tokens.
2650 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2651 handle jobs waiting for the load to drop.
2653 2005-04-23 Paul D. Smith <psmith@gnu.org>
2655 * main.c (main): Be careful to not core if a variable setting in
2656 the environment doesn't contain an '='. This is illegal but can
2657 happen in broken setups.
2658 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2660 2005-04-12 Paul D. Smith <psmith@gnu.org>
2662 The second expansion feature causes significant slowdown. Timing
2663 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2664 read the makefile before the feature, to 11+s to do the same
2665 operations after the feature. Additionally, memory usage
2666 increased drastically. To fix this I added some intelligence that
2667 avoids the overhead of the second expansion unless it's required.
2669 * dep.h: Add a new boolean field, need_2nd_expansion.
2671 * read.c (eval): When creating the struct dep for the target,
2672 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2673 (record_files): If there's a "%" in a static pattern rule, it gets
2674 converted to "$*" so set need_2nd_expansion to 1.
2676 * file.c (expand_deps): Rework to be more efficient. Only perform
2677 initialize_file_variables(), set_file_variables(), and
2678 variable_expand_for_file() if the need_2nd_expansion is set.
2680 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2681 (pattern_search): Ditto.
2682 * main.c (handle_non_switch_argument): Ditto.
2684 * read.c (read_all_makefiles): Ditto.
2685 (eval_makefile): Ditto.
2687 2005-04-07 Paul D. Smith <psmith@gnu.org>
2689 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2690 * variable.c (sync_Path_environment): Ditto.
2691 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2693 * main.c (main): Define the .FEATURES variable.
2694 * NEWS: Announce .FEATURES.
2695 * doc/make.texi (Special Variables): Document .FEATURES.
2697 * remake.c (check_dep): If a file is .PHONY, update it even if
2698 it's marked intermediate. Fixes Savannah bug #12331.
2700 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2702 * file.c (expand_deps): Factor out the second expansion and
2703 prerequisite line parsing logic from snap_deps().
2705 * file.c (snap_deps): Use expand_deps(). Expand and parse
2706 prerequisites of the .SUFFIXES special target first. Fixes
2707 Savannah bug #12320.
2709 2005-03-13 Paul D. Smith <psmith@gnu.org>
2711 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2714 2005-03-11 Paul D. Smith <psmith@gnu.org>
2716 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2717 available, not undefined (from Earnie Boyd).
2719 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2721 * implicit.c (pattern_search): Mark an intermediate target as
2722 precious if it happened to be a prerequisite of some (other)
2723 target. Fixes Savannah bug #12267.
2725 2005-03-09 Paul D. Smith <psmith@gnu.org>
2727 * read.c (eval_makefile): Add alloca(0).
2728 (eval_buffer): Ditto.
2730 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2732 * main.c (main): Use o_file instead of o_default when defining
2733 the .DEFAULT_TARGET special variable.
2734 * read.c (eval): Use define_variable_global() instead of
2735 define_variable() when setting new value for the .DEFAULT_TARGET
2736 special variable. Fixes Savannah bug #12266.
2738 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2740 * imlicit.c (pattern_search): Mark files for which an implicit
2741 rule has been found as targets. Fixes Savannah bug #12202.
2743 2005-03-04 Paul D. Smith <psmith@gnu.org>
2746 * doc/make.texi (Automatic Variables): Document $|.
2748 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2750 * read.c (record_files): Instead of substituting % with
2751 actual stem value in dependency list replace it with $*.
2752 This fixes stem triple expansion bug.
2754 * implicit.c (pattern_search): Copy stem to a separate
2755 buffer and make it a properly terminated string. Assign
2756 this buffer instead of STEM (which is not terminated) to
2757 f->stem. Instead of substituting % with actual stem value
2758 in dependency list replace it with $*. This fixes stem
2759 triple expansion bug.
2761 2005-03-01 Paul D. Smith <psmith@gnu.org>
2763 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2764 on Windows, as it takes a handle not a pid. Just exit.
2765 Fix from patch #3679, provided by Alessandro Vesely.
2767 * configure.in: Update check for sys_siglist[] from autoconf manual.
2768 * signame.c (strsignal): Update to use the new autoconf macro.
2770 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2772 * read.c (record_files): Add a check for the list of prerequisites
2773 of a static pattern rule being empty. Fixes Savannah bug #12180.
2775 2005-02-28 Paul D. Smith <psmith@gnu.org>
2777 * doc/make.texi (Text Functions): Update docs to allow the end
2778 ordinal for $(wordlist ...) to be 0.
2779 * function.c (func_wordlist): Fail if the start ordinal for
2780 $(wordlist ...) is <1. Matches documentation.
2781 Resolves Savannah support request #103195.
2783 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2784 previously we were stopping when !-q, exactly the opposite. This
2785 has been wrong since version 1.34, in 1994!
2786 (update_file): If we got an error don't break out to run more
2787 double-colon rules: just return immediately.
2788 Fixes Savannah bug #7144.
2790 2005-02-27 Paul D. Smith <psmith@gnu.org>
2792 * misc.c (end_of_token): Make argument const.
2793 * make.h: Update prototype.
2795 * function.c (abspath, func_realpath, func_abspath): Use
2796 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2797 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2798 * read.c (record_files): Ditto.
2799 * variable.c (do_variable_definition): Ditto.
2801 * function.c (func_error): Create a new function $(info ...) that
2802 simply prints the message to stdout with no extras.
2803 (function_table_init): Add new function to the table.
2804 * NEWS: Add $(info ...) reference.
2805 * doc/make.texi (Make Control Functions): Document it.
2807 New feature: if the system supports symbolic links, and the user
2808 provides the -L/--check-symlink-time flag, then use the latest
2809 mtime between the symlink(s) and the target file.
2811 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2812 readlink(). If both are available, define MAKE_SYMLINKS.
2813 * main.c: New variable: check_symlink_flag.
2814 (usage): Add a line for -L/--check-symlink-times to the help string.
2815 (switches): Add -L/--check-symlink-times command line argument.
2816 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2817 print a warning and disable it again.
2818 * make.h: Declare check_symlink_flag.
2819 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2820 if the file is a symlink then check each link in the chain and
2821 choose the NEWEST mtime we find as the mtime for the file. The
2822 newest mtime might be the file itself!
2823 * NEWS: Add information about this new feature.
2824 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2826 Avoid core dumps described in Savannah bug # 12124:
2828 * file.c: New variable snapped_deps remember whether we've run
2830 (snap_deps): Set it.
2831 * filedef.h: Extern it.
2832 * read.c (record_files): Check snapped_deps; if it's set then
2833 we're trying to eval a new target/prerequisite relationship from
2834 within a command script, which we don't support. Fatal.
2836 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2838 Implementation of the .DEFAULT_TARGET special variable.
2840 * read.c (eval): If necessary, update default_target_name when
2842 * read.c (record_files): Update default_target_file if
2843 default_target_name has changed.
2844 * main.c (default_target_name): Define.
2845 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2846 default_target_name is set use default_target_file as a root
2848 * filedef.h (default_target_name): Declare.
2849 * dep.h (free_dep_chain):
2850 * misc.c (free_dep_chain): Change to operate on struct nameseq
2851 and change name to free_ns_chain.
2852 * file.c (snap_deps): Update to use free_ns_chain.
2854 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2856 Implementation of the second expansion in explicit rules,
2857 static pattern rules and implicit rules.
2859 * read.c (eval): Refrain from chopping up rule's dependencies.
2860 Store them in a struct dep as a single dependency line. Remove
2861 the code that implements SySV-style automatic variables.
2863 * read.c (record_files): Adjust the code that handles static
2864 pattern rules to expand all percents instead of only the first
2865 one. Reverse the order in which dependencies are stored so that
2866 when the second expansion reverses them again they appear in
2867 the makefile order (with some exceptions, see comments in
2868 the code). Remove the code that implements SySV-style automatic
2871 * file.c (snap_deps): Implement the second expansion and chopping
2872 of dependency lines for explicit rules.
2874 * implicit.c (struct idep): Define an auxiliary data type to hold
2875 implicit rule's dependencies after stem substitution and
2878 * implicit.c (free_idep_chain): Implement.
2880 * implicit.c (get_next_word): Implement helper function for
2881 parsing implicit rule's dependency lines into words taking
2882 into account variable expansion requests. Used in the stem
2885 * implicit.c (pattern_search): Implement the second expansion
2886 for implicit rules. Also fixes bug #12091.
2888 * commands.h (set_file_variables): Declare.
2889 * commands.c (set_file_variables): Remove static specifier.
2891 * dep.h (free_dep_chain): Declare.
2892 * misc.c (free_dep_chain): Implement.
2894 * variable.h (variable_expand_for_file): Declare.
2895 * expand.c (variable_expand_for_file): Remove static specifier.
2897 * make.h (strip_whitespace): Declare.
2898 * function.c (strip_whitespace): Remove static specifier.
2900 2005-02-26 Paul D. Smith <psmith@gnu.org>
2902 * main.c (main): Check for ferror() when reading makefiles from stdin.
2903 Apparently some shells in Windows don't close pipes properly and
2906 2005-02-24 Jonathan Grant <jg@jguk.org>
2908 * configure.in: Add MinGW configuration options, and extra w32 code
2910 * Makefile.am: Add MinGW configuration options, and extra w32 code
2912 * main.c: Determine correct program string (after last \ without .exe).
2913 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2915 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2916 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2917 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2918 environment support.
2920 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2922 * function.c (func_shell): When initializing error_prefix, check
2923 that reading file name is not null. This fixes long-standing
2924 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2926 2005-02-09 Paul D. Smith <psmith@gnu.org>
2928 * maintMakefile: Update the CVS download URL to simplify them.
2929 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2930 downloading the .texi files from Savannah now.
2932 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2934 * main.c (handle_non_switch_argument): Only add variables to
2935 command_variables if they're not already there: duplicate settings
2936 waste space and can be confusing to read.
2938 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2939 this header is never included by non-WINDOWS32 code, and it
2940 requires <config.h> to define which isn't always included first.
2942 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2943 testing MINGW32 versions.
2945 * main.c (log_working_directory): flush stdout to be sure the WD
2946 change is printed before any stderr messages show up.
2948 2005-02-01 Paul D. Smith <psmith@gnu.org>
2950 * maintMakefile (po_repo): Update the GNU translation site URL.
2952 2004-12-01 Paul D. Smith <psmith@gnu.org>
2954 * main.c (main): Change char* env_shell to struct variable shell_var.
2955 * variable.c (target_environment): Use new shell_var.
2957 2004-11-30 Paul D. Smith <psmith@gnu.org>
2959 * configure.in: The old way we avoided creating build.sh from
2960 build.sh.in before build.sh.in exists doesn't work anymore; we
2961 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2962 the help!). This also keeps automake from complaining.
2963 * Makefile.am (README): Add a dummy target so automake won't
2964 complain that this file doesn't exist when we checkout from CVS.
2965 * maintMakefile (.dep_segment): Rewrite this rule since newer
2966 versions of automake don't provide DEP_FILES.
2968 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2970 Implementation of `realpath' and `abspath' built-in functions.
2972 * configure.in: Check for realpath.
2973 * function.c (abspath): Return an absolute file name that does
2974 not contain any `.' or `..' components, nor repeated `/'.
2975 * function.c (func_abspath): For each name call abspath.
2976 * function.c (func_realpath): For each name call realpath
2977 from libc or delegate to abspath if realpath is not available.
2978 * doc/make.texi (Functions for File Names): Document new functions.
2979 * doc/make.texi (Quick Reference): Ditto.
2981 2004-11-28 Paul D. Smith <psmith@gnu.org>
2983 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2984 arguments. Fixes bug #10252.
2986 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2988 * main.c (main): Set SHELL to v_noexport by default. Remember the
2989 original environment setting of SHELL in the env_shell variable.
2990 * main.h: Export new env_shell variable.
2991 * variable.c (target_environment): If we find a v_noexport
2992 variable for SHELL, add a SHELL variable with the env_shell value.
2993 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2994 * doc/make.texi (Variables/Recursion): Ditto.
2996 2004-11-28 Paul D. Smith <psmith@gnu.org>
2998 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2999 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
3000 Patch by Alessandro Vesely.
3002 2004-11-12 Paul D. Smith <psmith@gnu.org>
3004 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
3005 the command line if it's inside a string.
3006 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
3008 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
3010 * function.c (func_lastword): New function: return last word
3011 from the list of words.
3012 * doc/make.texi: Document $(lastword ). Fix broken links in
3013 Quick Reference section.
3015 2004-10-06 Paul D. Smith <psmith@gnu.org>
3017 Apply patch from Alessandro Vesely, provided with bug # 9748.
3018 Fix use of tmpnam() to work with Borland C.
3020 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
3021 construction of a temporary filename, and call new function
3022 create_batch_filename().
3023 (create_batch_filename) [WINDOWS32]: New function to create a
3026 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
3028 * read.c (record_target_var): Expand simple pattern-specific
3030 * variable.c (initialize_file_variables): Do not expand simple
3031 pattern-specific variable.
3033 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
3035 * remake.c (update_file_1): When rebuilding makefiles inherit
3036 dontcare flag from a target that triggered update.
3038 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
3040 * variable.c (initialize_file_variables): Mark pattern-specific
3041 variable as a per-target and copy export status.
3043 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
3045 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
3047 * implicit.c (pattern_search): When considering an implicit rule's
3048 prerequisite check that it is actually a target rather then
3049 just an entry in the file hashtable.
3051 2004-09-21 Paul D. Smith <psmith@gnu.org>
3053 * read.c (readstring): Fix some logic errors in backslash handling.
3054 (eval): Remove some unnecessary processing in buffer handling.
3055 (record_target_var): Assert that parse_variable_definition() succeeded.
3056 Reported by: Markus Mauhart <qwe123@chello.at>.
3058 * misc.c: Removed the sindex() function. All instances of this
3059 function were trivially replaceable by the standard strstr()
3060 function, and that function will always have better (or certainly
3061 no worse) performance than the very simple-minded algorithm
3062 sindex() used. This can matter with complex makefiles.
3063 * make.h: Remove the prototype for sindex().
3064 * function.c (subst_expand): Convert sindex() call to strstr().
3065 This means we no longer need to track the TLEN value so remove that.
3066 (func_findstring): Convert sindex() to strstr().
3067 * commands.c (chop_commands): Convert sindex() calls to strstr().
3068 Suggested by: Markus Mauhart <qwe123@chello.at>.
3070 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
3071 idea behind Savannah Patch #3144 from david.baird@homemail.com.
3072 If SHELL is set to CMD.EXE then assume it's batch-mode and
3073 non-unixy. I wrote the code differently from the patch, though,
3074 to make it safer. This also resolves bug #9174.
3076 2004-09-20 Paul D. Smith <psmith@gnu.org>
3078 * expand.c (variable_expand_string): Modify to invoke
3079 patsubst_expand() instead of subst_expand(); the latter didn't
3080 handle suffix patterns correctly.
3081 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
3082 was used only from variable_expand_string() and is no longer used
3084 (func_subst): Ditto, on call to subst_expand().
3085 (patsubst_expand): Require the percent pointers to point to the
3086 character after the %, not to the % itself.
3087 * read.c (record_files): New call criteria for patsubst_expand().
3088 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
3089 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
3091 2004-09-19 Paul D. Smith <psmith@gnu.org>
3093 * function.c (subst_expand): Fix a check in by_word: look for a
3094 previous blank if we're beyond the beginning of the string, not
3095 the beginning of the word.
3096 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3098 2004-05-16 Paul D. Smith <psmith@gnu.org>
3100 * remake.c (update_goal_chain): Change the argument specifying
3101 whether we're rebuilding makefiles to be a global variable,
3102 REBUILDING_MAKEFILES.
3103 (complain): Extract the code that complains about no rules to make
3104 a target into a separate function.
3105 (update_file_1): If we tried to rebuild a file during the makefile
3106 rebuild phase and it was dontcare, then no message was printed.
3107 If we then try to build the same file during the normal build,
3108 print a message this time.
3109 (remake_file): Don't complain about un-remake-able files when
3110 we're rebuilding makefiles.
3112 2004-05-11 Paul D. Smith <psmith@gnu.org>
3114 * job.c (construct_command_argv_internal): OS/2 patches from
3115 Andreas Buening <andreas.buening@nexgo.de>.
3117 2004-05-10 Paul D. Smith <psmith@gnu.org>
3119 * remake.c (update_file): Don't walk the double-colon chain unless
3120 this is a double-colon rule. Fix suggested by Boris Kolpackov
3121 <boris@kolpackov.net>.
3123 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3124 * readme.vms: New section describing OpenVMS support and issues.
3125 * default.c (default_variables): Add support for IA64.
3126 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3127 without some privilege aborts make with the error
3128 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3129 pressing Ctrl+Y and the input device is no terminal. The change
3130 catches this error and just continues.
3132 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3134 2004-04-25 Paul D. Smith <psmith@gnu.org>
3136 * commands.c (set_file_variables): Set $< properly in the face of
3137 order-only prerequisites.
3138 Patch from Boris Kolpackov <boris@kolpackov.net>
3140 2004-04-21 Bob Byrnes <byrnes@curl.com>
3142 * main.c (main): Notice failures to remake makefiles.
3144 2004-03-28 Paul D. Smith <psmith@gnu.org>
3146 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3148 * job.c: No default shell for RISC OS.
3149 (load_too_high): Hard-code the return to 1.
3150 (construct_command_argv_internal): No sh_chars or sh_cmds.
3151 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3153 2004-03-20 Paul D. Smith <psmith@gnu.org>
3155 * variable.c (do_variable_definition): Don't append from the
3156 global set if a previous non-appending target-specific variable
3157 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3160 * expand.c (reference_variable): Don't give up on variables with
3161 no value that have the target-specific append flag set: they might
3162 have a value after all. Reported by Oliver Schmidt
3163 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3164 <nikulin@dx1cmd.inp.nsk.su>.
3166 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3167 refer to absolute pathnames in directories that don't exist: some
3168 portion of the makefile could create those directories before we
3169 match the pattern. Fixes bugs #775 and #108.
3171 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3173 * main.c (main): Free makefile_mtimes if we have any.
3174 * README.W32.template: Update documentation for the current status
3175 of the MS-Windows port.
3176 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3177 environment variable is sometimes already defined which causes the
3179 * main.c (debug_signal_handler): Only define this function if
3180 SIGUSR1 is available.
3182 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3184 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3185 * README.OS2.template: Documentation updates.
3186 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3187 link line for safety.
3188 * maintMakefile (build.sh.in): Remove an extraneous ")".
3189 * job.c (child_execute_job): Close saved FDs.
3190 * job.c (exec_command) [OS/2]: exec_command(): If the command
3191 can't be exec'ed and if the shell is not Unix-sh, then try again
3192 with argv = { "cmd", "/c", ... }. Normally, this code is never
3193 reached for the cmd shell unless the command really doesn't exist.
3194 (construct_command_argv_internal) [OS/2]: The code for cmd
3195 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3196 The CMD builtin commands are case insensitive so use strcasecmp().
3198 2004-03-19 Paul D. Smith <psmith@gnu.org>
3200 * read.c (do_define): Re-order line counter increment so the count
3201 is accurate (we were losing one line per define). Reported by
3202 Dave Yost <Dave@Yost.com>.
3204 2004-03-06 Paul D. Smith <psmith@gnu.org>
3206 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3208 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3209 * misc.c (message,error,fatal): Ditto.
3210 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3211 * config.h.W32.template: Ditto.
3212 * config.h-vms.template: Ditto.
3213 * config.ami.template: Ditto.
3215 2004-03-04 Paul D. Smith <psmith@gnu.org>
3217 * README.template: Add a note about broken /bin/sh on SunOS
3218 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3220 * misc.c (message, error, fatal): Don't use "..." if we're using
3221 varargs. ansi2knr should handle this but it doesn't work: it
3222 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3223 done. On many systems (SunOS for example) va_dcl is a #define.
3224 So, force the use of the non-"..." version on pre-ANSI compilers.
3226 * maintMakefile (sign-dist): Create some rules to help automate
3227 the new GNU ftp upload method.
3229 2004-02-24 Paul D. Smith <psmith@gnu.org>
3231 * config.h.W32.template: Add HAVE_STDARG_H
3232 * config.h-vms.template: Ditto.
3233 * config.ami.template: Ditto.
3235 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3237 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3238 * build_w32.bat: Remove extra "+".
3240 2004-02-23 Paul D. Smith <psmith@gnu.org>
3242 * make.h: Create an UNUSED macro to mark unused parameters.
3243 * (many): Clean up warnings by applying UNUSED, fixing
3244 signed/unsigned incompatibilities, etc.
3246 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3248 * filedef.h: Name the command_state enumeration.
3249 * file.c (set_command_state): Use the enumeration in the function
3252 * configure.in: Explicitly set SET_MAKE to empty, to disable
3253 MAKE=make even when no make already exists. Fix bug #3823.
3255 2004-02-22 Paul D. Smith <psmith@gnu.org>
3257 * maintMakefile: Perl script to clean up all non-CVS files. Use
3258 it on all the subdirectories for the cvs-clean target.
3260 * main.c (decode_switches): Require non-empty strings for all our
3261 string command-line options. Fixes Debian bug # 164165.
3263 * configure.in: Check for stdarg.h and varargs.h.
3264 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3265 for printing messages.
3266 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3271 A number of patches for OS/2 support from Andreas Buening
3272 <andreas.buening@nexgo.de>:
3274 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3275 disable the SIGCHLD handler.
3276 (reap_children) [OS/2]: Remove special handling of job_rfd.
3277 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3278 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3279 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3280 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3281 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3284 2004-02-21 Paul D. Smith <psmith@gnu.org>
3286 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3287 <mail@kristov.de> reports that if process_begin() fails we don't
3288 handle the error condition correctly in all cases.
3289 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3290 to have a newline on the message.
3292 * job.c (construct_command_argv_internal): Add "test" to UNIX
3293 sh_cmds[]. Fixes Savannah bug # 7606.
3295 2004-02-04 Paul D. Smith <psmith@gnu.org>
3297 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3298 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3299 Hartmut Becker <Hartmut.Becker@hp.com>.
3301 2004-01-21 Paul D. Smith <psmith@gnu.org>
3303 * job.c (load_too_high): Implement an algorithm to control the
3304 "thundering herd" problem when using -l to control job creation
3305 via the load average. The system only recomputes the load once a
3306 second but we can start many jobs in a second. To solve this we
3307 keep track of the number of jobs started in the last second and
3308 apply a weight to try to guess what a correct load would be.
3309 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3310 Also fixes bug #4693.
3311 (reap_children): Decrease the job count for this second.
3312 (start_job_command): Increase the job count for this second.
3314 * read.c (conditional_line): Expand the text after ifn?def before
3315 checking to see if it's a single word. Fixes bug #7257.
3317 2004-01-09 Paul D. Smith <psmith@gnu.org>
3319 * file.c (print_file): Recurse to print all targets in
3320 double-colon rules. Fixes bug #4518, reported (with patch) by
3321 Andrew Chatham <chatham@google.com>.
3323 2004-01-07 Paul D. Smith <psmith@gnu.org>
3325 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3326 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3327 AC_FUNC_SETVBUF_REVERSED.
3329 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3330 (MAKE Variable): Fix Savannah bug #4898.
3332 * job.c (construct_command_argv_internal): Add "!" to the list of
3333 shell escape chars. POSIX sh allows it to appear before a
3334 command, to negate the exit code. Fixes bug #6404.
3336 * implicit.c (pattern_search): When matching an implicit rule,
3337 remember which dependencies have the ignore_mtime flag set.
3338 Original fix provided in Savannah patch #2349, by Benoit
3339 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3341 2003-11-22 Paul D. Smith <psmith@gnu.org>
3343 * README.W32.template (Outputs): Clarification on -j with
3344 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3347 2003-11-02 Paul D. Smith <psmith@gnu.org>
3349 * function.c (func_if): Strip all the trailing whitespace from the
3350 condition, then don't expand it. Fixed bug # 5798.
3352 * expand.c (recursively_expand_for_file): If we're expanding a
3353 variable with no file context, then use the variable's context.
3356 2003-10-21 Paul D. Smith <psmith@gnu.org>
3358 * main.c (log_working_directory): Add newlines to printf()s.
3360 * README.cvs: Add a note to ignore warnings during autoreconf.
3362 * maintMakefile (po_repo): Set a new URL for PO file updates.
3363 (get-config/config.guess get-config/config.sub): Get these files
3364 from the Savannah config project instead of ftp.gnu.org.
3366 2003-10-05 Paul Eggert <eggert@twinsun.com>
3368 * main.c (main): Avoid potential subscript error if environ has
3371 2003-08-22 Paul D. Smith <psmith@gnu.org>
3373 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3374 systems which don't yet implement the C89 standard :-/.
3376 2003-07-18 Paul D. Smith <psmith@gnu.org>
3378 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3379 [WINDOWS32]: Initialize hash.
3381 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3383 * dir.c (read_dirstream): Provide a workaround for broken versions of
3384 the MinGW dirent structure.
3386 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3388 * w32/include/dirent.h: Add __MINGW32__ filter.
3390 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3392 * make.h: Add global declaration of *make_host.
3393 * main.c (print_usage): Remove local declaration of *make_host.
3394 (print_version): Display "This program built for ..." after Copyright
3397 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3399 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3400 execution of "makeinfo --html make.texi".
3402 2003-04-30 Paul D. Smith <psmith@gnu.org>
3404 * build.template: Make some changes to maybe allow this script to
3405 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3407 * README.OS2.template: New file for OS/2 support. Original
3408 contributed by Andreas Buening.
3409 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3412 2003-04-19 Paul D. Smith <psmith@gnu.org>
3414 Fix bug #1405: allow a target to match multiple pattern-specific
3417 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3418 variable.c, where they've always belonged.
3419 * rule.h: Move the prototypes and struct pattern_var as well.
3420 * variable.c (initialize_file_variables): Invoke
3421 lookup_pattern_var() in a loop, until no more matches are found.
3422 If a match is found, create a new variable set for the target's
3423 pattern variables. Then merge the contents of each matching
3424 pattern variable set into the target's pattern variable set.
3425 (lookup_pattern_var): Change this function to be usable
3426 in a loop. It takes a starting position: if NULL, start at the
3427 beginning; if non-NULL, start with the pattern variable after that
3428 position, and return the next matching pattern.
3429 (create_pattern_var): Create a unique instance of
3430 pattern-specific variables for every definition in the makefile.
3431 Don't combine the same pattern together. This allows us to
3432 process the variable handling properly even when the same pattern
3433 is used multiple times.
3434 (parse_variable_definition): New function: break out the parsing
3435 of a variable definition line from try_variable_definition.
3436 (try_variable_definition): Call parse_variable_definition to
3438 (print_variable_data_base): Print out pattern-specific variables.
3439 * variable.h (struct variable): Remember when a variable is
3440 conditional. Also remember its flavor.
3441 (struct pattern_var): Instead of keeping a variable set, we just
3442 keep a single variable for each pattern.
3443 * read.c (record_target_var): Each pattern variable contains only a
3444 single variable, not a set, so create it properly.
3445 * doc/make.texi (Pattern-specific): Document the new behavior.
3447 2003-04-17 Paul D. Smith <psmith@gnu.org>
3449 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3450 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3451 file/directory naming rules for VMS so I can't tell whether this
3454 2003-04-09 Paul D. Smith <psmith@gnu.org>
3456 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3457 DOS-style pathnames: backslash separators and drive specifiers.
3459 2003-03-28 Paul D. Smith <psmith@gnu.org>
3461 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3462 the intermediate flag on all targets. Fixes bug #2515.
3464 2003-03-24 Paul D. Smith <psmith@gnu.org>
3466 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3467 Upgrade to autoconf 2.57 and automake 1.7.3.
3469 * job.c: More OS/2 changes from Andreas Buening.
3471 * file.c (print_file): Fix variable initialization.
3474 * remake.c (notice_finished_file):
3476 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3477 some calls (like readdir()) return NULL in valid situations
3478 without resetting errno. Fixes bug #2846.
3480 2003-02-25 Paul D. Smith <psmith@gnu.org>
3482 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3484 * job.c (_is_unixy_shell) [OS/2]: New function.
3485 Set default shell to /bin/sh.
3486 (reap_children): Close the job_rfd pipe here since we don't use a
3488 (set_child_handler_action_flags): define this to empty on OS/2.
3489 (start_job_command): Close the jobserver pipe and use
3490 child_execute_job() instead of fork/exec.
3491 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3492 rather than exec'ing, then reconfigure stdin/stdout.
3493 (exec_command): Rewrite to use spawn instead of exec. Return the
3496 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3497 in DOS. Handle the TEMP environment variable as in DOS. Don't
3498 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3499 use -j in DOS mode. Use child_execute_job() instead of
3502 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3505 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3506 prototypes that return values.
3508 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3510 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3511 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3513 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3516 2003-02-24 Paul D. Smith <psmith@gnu.org>
3518 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3519 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3520 (child_execute_job) [VMS]: Handle error status properly.
3521 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3523 * function.c (func_shell): Use EINTRLOOP() while reading from the
3524 subshell pipe (Fixes bug #2502).
3525 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3527 * main.c (main): Ditto.
3529 2003-01-30 Paul D. Smith <psmith@gnu.org>
3531 * read.c (eval): eval() was not fully reentrant, because the
3532 collapsed buffer was static. Change it to be an automatic
3533 variable so that eval() can be invoked recursively.
3535 (eval): Apply patch # 1022: fix memory reference error on long
3536 target-specific variable lines.
3537 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3539 * function.c (check_numeric): Combine the is_numeric() function
3540 into this function, since it's only called from one place.
3541 Constify this function. Have it print the incorrect string in the
3542 error message. Fixes bug #2407.
3543 (strip_whitespace): Constify.
3544 (func_if): Constify.
3545 * expand.c (expand_argument): Constify.
3547 2003-01-29 Paul D. Smith <psmith@gnu.org>
3549 Fix bug # 2169, also reported by other people on various systems.
3551 * make.h: Some systems, such as Solaris and PTX, do not fully
3552 implement POSIX-compliant SA_RESTART functionality; important
3553 system calls like stat() and readdir() can still fail with EINTR
3554 even if SA_RESTART has been set on the signal handler. So,
3555 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3556 EINTR for system calls which return -1 or 0 (NULL), respectively,
3558 Also, remove the old atomic_stat()/atomic_readdir() and
3559 HAVE_BROKEN_RESTART handling.
3561 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3563 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3564 * remake.c (touch_file): Ditto.
3566 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3567 * read.c (construct_include_path): Ditto.
3568 * remake.c (name_mtime): Ditto.
3569 * vpath.c (selective_vpath_search): Ditto.
3570 * dir.c (find_directory): Ditto.
3571 (local_stat): Ditto.
3572 (find_directory): Use ENULLLOOP() to wrap opendir().
3573 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3575 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3576 atomic_readdir() handling.
3578 2003-01-22 Paul D. Smith <psmith@gnu.org>
3580 * function.c (func_call): Fix Bug #1744. If we're inside a
3581 recursive invocation of $(call ...), mask any of the outer
3582 invocation's arguments that aren't used by this one, so that this
3583 invocation doesn't "inherit" them accidentally.
3585 2002-12-05 Paul D. Smith <psmith@gnu.org>
3587 * function.c (subst_expand): Valery Khamenia reported a
3588 pathological performance hit when doing substitutions on very
3589 large values with lots of words: turns out we were invoking
3590 strlen() a ridiculous number of times. Instead of having each
3591 call to sindex() call strlen() again, keep track of how much of
3592 the text we've seen and pass the length to sindex().
3594 2002-11-19 Paul D. Smith <psmith@gnu.org>
3596 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3599 2002-11-16 Paul D. Smith <psmith@gnu.org>
3601 * NMakefile.template (OBJS): Add hash.c object file.
3602 * SMakefile.template (srcs): Ditto.
3603 * Makefile.ami (objs): Ditto.
3604 * build_w32.bat: Ditto.
3606 * Makefile.DOS.template: Remove extra dependencies.
3608 2002-10-25 Paul D. Smith <psmith@gnu.org>
3610 * expand.c (install_variable_buffer): New function. Install a new
3611 variable_buffer context and return the previous one.
3612 (restore_variable_buffer): New function. Free the current
3613 variable_buffer context and put a previously saved one back.
3614 * variable.h: Prototypes for {install,restore}_variable_buffer.
3615 * function.c (func_eval): Push a new variable_buffer context
3616 before we eval, then restore the old one when we're done.
3619 * read.c (install_conditionals): New function. Install a new
3620 conditional context and return the previous one.
3621 (restore_conditionals): New function. Free the current
3622 conditional context and put a previously saved one back.
3623 (eval): Use the {install,restore}_conditionals for "include"
3625 (eval_buffer): Use {install,restore}_conditionals to preserve the
3626 present conditional state before we evaluate the buffer.
3629 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3631 (Recursion): Add a variable index entry for CURDIR.
3633 * README.cvs: Update to appropriate versions.
3634 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3635 don't need to copy loadavg.c: automake is smart enough to create
3636 it for me. Still have a bug in automake related to ansi2knr tho.
3638 2002-10-14 Paul D. Smith <psmith@gnu.org>
3640 * remake.c (notice_finished_file): Only touch targets if they have
3641 at least one command (as per POSIX). Resolve Bug #1418.
3643 * *.c: Convert to using ANSI C-style function definitions.
3644 * Makefile.am: Enable the ansi2knr feature of automake.
3645 * configure.in: ditto.
3647 2002-10-13 Paul D. Smith <psmith@gnu.org>
3649 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3650 for automatic variable values like $^, etc. In the case of very
3651 large lists of prerequisites this causes problems. Instead reuse
3652 a static buffer (resizeable) for each variable.
3654 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3655 target-specific variable definitions. Check for it and set an
3657 (record_target_var): Set the export field to v_export if the
3658 "exported" flag is set.
3659 * doc/make.texi (Target-specific): Document the ability to use
3662 * doc/make.texi: Change the name of the section on automatic
3663 variables from "Automatic" to "Automatic Variables". Added text
3664 clarifying the scope of automatic variables.
3666 2002-10-04 Paul D. Smith <psmith@gnu.org>
3668 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3670 (record_files): Ditto.
3672 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3673 the search for the '=' to only within the enclosing parens.
3675 2002-10-03 Paul D. Smith <psmith@gnu.org>
3677 Version 3.80 released.
3679 * dir.c: Change hash functions to use K&R function definition style.
3680 * function.c: Ditto.
3682 * variable.c: Ditto.
3684 Update to automake 1.7.
3686 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3687 (pdf): Remove this target as automake now provides one.
3689 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3691 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3693 * makefile.com: Updates for GNU make 3.80.
3694 * makefile.vms: Ditto.
3696 2002-09-23 Paul D. Smith <psmith@gnu.org>
3698 * read.c (enum make_word_type): Remove w_comment.
3699 (get_next_mword): Don't treat comment characters as special; where
3700 this function is used we will never see a comment (it's stripped
3701 before we get here) and treating comments specially means that
3702 targets like "foo\#bar" aren't handled properly.
3704 2002-09-18 Paul D. Smith <psmith@gnu.org>
3706 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3708 * read.c (eval): Expansion of arguments to export/unexport was
3709 ignoring all arguments after the first one. Change the algorithm
3710 to expand the whole line once, then parse the results.
3712 2002-09-17 Paul D. Smith <psmith@gnu.org>
3714 Fix Bug #940 (plus another bug I found while looking at this):
3716 * read.c (record_target_var): enter_file() will add a new entry if
3717 it's a double-colon target: we don't want to do that in this
3718 situation. Invoke lookup_file() and only enter_file() if it does
3719 not already exist. If the file we get back is a double-colon then
3720 add this variable to the "root" double-colon target.
3722 * variable.c (initialize_file_variables): If this file is a
3723 double-colon target but is not the "root" target, then initialize
3724 the root and make the root's variable list the parent of our
3727 2002-09-13 Paul D. Smith <psmith@gnu.org>
3729 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3731 * hash.c (round_up_2): Get rid of a warning.
3733 2002-09-12 Paul D. Smith <psmith@gnu.org>
3735 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3736 so it doesn't complain about getloadavg.c.
3738 * commands.c (set_file_variables): Make sure we always alloca() at
3739 least 1 character for the value of $? (for '\0').
3741 2002-09-11 Paul D. Smith <psmith@gnu.org>
3743 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3744 macro to use RESULT instead of the incorrect _RESULT_.
3746 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3747 and atomic_readdir(). We need to #include dirent.h to get this to
3749 * misc.c (atomic_readdir): Fix typos.
3751 2002-09-10 Paul D. Smith <psmith@gnu.org>
3753 * read.c (eval): Expand variable lists given to export and
3754 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3755 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3757 * doc/make.texi (Variables/Recursion): Document this.
3758 (Conditional Syntax): And here.
3760 2002-09-09 Paul D. Smith <psmith@gnu.org>
3762 * configure.in: Check for memmove().
3764 2002-09-07 Paul D. Smith <psmith@gnu.org>
3766 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3767 Michael Sterrett <msterret@coat.com> reports that while it has
3768 SA_RESTART, it does not work properly.
3770 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3771 that invokes stat() and loops to do it again if it returns EINTR.
3772 (atomic_readdir): Ditto, with readdir().
3774 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3775 and readdir() to atomic_stat() and atomic_readdir().
3777 2002-09-04 Paul D. Smith <psmith@gnu.org>
3779 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3780 reports that GNU make sometimes doesn't recognize that targets can
3781 be made, when directories can be created as prerequisites. He
3782 reports that changing the order of predicates in the DEP->changed
3783 flag test so that lookup_file() is always performed, solves this
3786 2002-08-08 Paul D. Smith <psmith@gnu.org>
3788 * configure.in: Require a newer version of gettext.
3790 * misc.c (perror_with_name): Translate the format string (for
3791 right-to-left language support).
3792 (pfatal_with_name): Ditto.
3794 * main.c: Create a static array of strings to store the usage
3795 text. This is done to facilitate translations.
3796 (struct command_switch): Remove argdesc and description fields.
3797 (switches): Remove values for obsolete fields.
3798 (print_usage): Print each element of the usage array.
3800 * hash.c: Change function definitions to be K&R style.
3802 2002-08-02 Paul D. Smith <psmith@gnu.org>
3804 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3805 this one because it's too hard to get right. We'll look at it for
3807 * main.c (main): Don't create the .TARGETS variable.
3808 * variable.c (handle_special_var): Don't handle .TARGETS.
3810 2002-08-01 Paul D. Smith <psmith@gnu.org>
3812 * main.c (switches): Add a new option, -B (--always-make). If
3813 specified, make will rebuild all targets that it encounters even
3814 if they don't appear to be out of date.
3815 (always_make_flag): New flag.
3816 * make.h: Extern always_make_flag.
3817 * remake.c (update_file_1): Check always_make_flag; if it's set we
3818 will always rebuild any target we can, even if none of its
3819 prerequisites are newer.
3822 * doc/make.texi (Shell Function): Make it clear that make
3823 variables marked as "export" are not passed to instances of the
3826 Add new introspection variable .VARIABLES and .TARGETS.
3828 * variable.c (handle_special_var): New function. If the variable
3829 reference passed in is "special" (.VARIABLES or .TARGETS),
3830 calculate the new value if necessary. .VARIABLES is handled here:
3831 walk through the hash of defined variables and construct a value
3832 which is a list of the names. .TARGETS is handled by
3833 build_target_list().
3834 (lookup_variable): Invoke handle_special_var().
3835 * file.c (build_target_list): Walk through the hask of known files
3836 and construct a list of the names of all the ones marked as
3838 * main.c (main): Initialize them to empty (and as simple variables).
3839 * doc/make.texi (Special Variables): Document them.
3840 * NEWS: Mention them.
3842 * variable.h (struct variable): Add a new flag "exportable" which
3843 is true if the variable name is valid for export.
3844 * variable.c (define_variable_in_set): Set "exportable" when a new
3845 variable is defined.
3846 (target_environment): Use the "exportable" flag instead of
3847 re-checking the name here... an efficiency improvement.
3849 2002-07-31 Paul D. Smith <psmith@gnu.org>
3851 * config.h-vms.template: Updates to build on VMS. Thanks to
3852 Brian_Benning@aksteel.com for helping verify the build.
3853 * makefile.com: Build the new hash.c file.
3854 * hash.h: Use strcpmi(), not stricmp(), in the
3855 HAVE_CASE_INSENSITIVE_FS case.
3857 2002-07-30 Paul D. Smith <psmith@gnu.org>
3859 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3860 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3861 Reported by <Brian_Benning@aksteel.com>.
3863 2002-07-10 Paul D. Smith <psmith@gnu.org>
3865 * variable.c (pop_variable_scope): Remove variable made unused by
3866 new hash infrastructure.
3867 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3868 comparisons as well as name comparisons.
3869 * variable.h: Add a prototype for new hash_init_function_table().
3870 * file.c (lookup_file): Remove variables made unused by new hash
3872 * dir.c (directory_contents_hash_2): Missing return of hash value.
3873 (dir_contents_file_exists_p): Remove variables made unused by new
3874 hash infrastructure.
3877 Installed Greg McGary's integration of the hash functions from the
3878 GNU id-utils package:
3880 2002-07-10 Greg McGary <greg@mcgary.org>
3882 * scripts/functions/filter-out: Add literals to to the
3883 pattern space in order to add complexity, and trigger
3884 use of an internal hash table. Fix documentation strings.
3885 * scripts/targets/INTERMEDIATE: Reverse order of files
3886 passed to expected `rm' command.
3888 2002-07-10 Greg McGary <greg@mcgary.org>

3980 2002-07-10 Paul D. Smith <psmith@gnu.org>
3982 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3983 prerequisite list. A real SysV make will expand the entire
3984 prerequisites list _twice_: we don't do that as it's a big
3985 backward-compatibility problem. We only replace those specific
3988 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3989 references left in the list of prerequisites. Check for .POSIX as
3990 we record targets, so we can disable non-POSIX behavior while
3991 reading makefiles as well as running them.
3992 (eval): Check the prerequisite list to see if we have anything
3993 that looks like a SysV prerequisite variable reference.
3995 2002-07-09 Paul D. Smith <psmith@gnu.org>
3997 * doc/make.texi (Prerequisite Types): Add a new section describing
3998 order-only prerequisites.
4000 * read.c (uniquize_deps): If we have the same file as both a
4001 normal and order-only prereq, get rid of the order-only prereq,
4002 since the normal one supersedes it.
4004 2002-07-08 Paul D. Smith <psmith@gnu.org>
4006 * AUTHORS: Added Greg McGary to the AUTHORS file.
4007 * NEWS: Blurbed order-only prerequisites.
4008 * file.c (print_file): Show order-only deps properly when printing
4011 * maintMakefile: Add "update" targets for wget'ing the latest
4012 versions of various external files. Taken from Makefile.maint in
4015 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
4016 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
4018 2002-07-07 Paul D. Smith <psmith@gnu.org>
4020 * po/*.po: Remove. We'll use wget to retrieve them at release
4023 * variable.c (do_variable_definition) [W32]: On W32 using cmd
4024 rather than a shell you get an exception. Make sure we look up
4025 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
4027 * remake.c (notice_finished_file): Fix handling of -t flag.
4028 Patch provided by Henning Makholm <henning@makholm.net>.
4030 * implicit.c (pattern_search): Some systems apparently run short
4031 of stack space, and using alloca() in this function caused an
4032 overrun. I modified it to use xmalloc() on the two variables
4033 which seemed like they might get large. Fixes Bug #476.
4035 * main.c (print_version): Update copyright notice to conform with
4037 (print_usage): Update help output.
4039 * function.c (func_eval): Create a new make function, $(eval
4040 ...). Expand the arguments, put them into a buffer, then invoke
4041 eval_buffer() on the resulting string.
4042 (func_quote): Create a new function, $(quote VARNAME). Inserts
4043 the value of the variable VARNAME without expanding it any
4046 * read.c (struct ebuffer): Change the linebuffer structure to an
4047 "eval buffer", which can be either a file or a buffer.
4048 (eval_makefile): Move the code in the old read_makefile() which
4049 located a makefile into here: create a struct ebuffer with that
4050 information. Have it invoke the new function eval() with that
4052 (eval_buffer): Create a new function that creates a struct ebuffer
4053 that holds a string buffer instead of a file. Have it invoke
4054 eval() with that ebuffer.
4055 (eval): New function that contains the guts of the old
4056 read_makefile() function: this function parses makefiles. Obtains
4057 data to parse from the provided ebuffer. Some modifications to
4058 make the flow of the function cleaner and clearer. Still could
4059 use some work here...
4060 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
4061 contents of the define/endef variable from the ebuffer.
4062 (readstring): Read the next line from a string-style ebuffer.
4063 (readline): Read the next line from an ebuffer. If it's a string
4064 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
4067 * dep.h (eval_buffer): Prototype eval_buffer();
4069 * variable.c (do_variable_definition): Make sure that all
4070 non-target-specific variables are registered in the global set.
4071 If we're invoked from an $(eval ...) we might be inside a $(call
4072 ...) or other function which has pushed a variable scope; we still
4073 want to define our variables from evaluated makefile code in the
4076 2002-07-03 Greg McGary <greg@mcgary.org>
4078 * dep.h (struct dep) [ignore_mtime]: New member.

4084 (read_makefile): Parse '|' in prerequisite list.
4085 (uniquize_deps): Consider ignore_mtime when comparing deps.
4086 * remake.c (update_file_1, check_dep): Don't force remake for
4087 dependencies that have d->ignore_mtime.
4088 * commands.c (FILE_LIST_SEPARATOR): New constant.
4089 (set_file_variables): Don't include a
4090 prerequisite in $+, $^ or $? if d->ignore_mtime.
4093 2002-06-18 Paul D. Smith <psmith@gnu.org>
4095 * make.texinfo: Updates for next revision. New date/rev/etc.
4096 Recreate all Info menus. Change license on the manual to the GNU
4097 Free Documentation License. A number of typos.
4098 (Variables Simplify): Don't use "-" before it's defined.
4099 (Automatic Prerequisites): Rewrite the target example to work
4100 properly if the compile fails. Remove incorrect comments about
4101 how "set -e" behaves.
4102 (Text Functions): Move the "word", "wordlist", "words", and
4103 "firstword" functions here, from "File Name Functions".
4104 * make-stds.texi: Update from latest GNU version.
4105 * fdl.texi: (created) Import the latest GNU version.
4107 2002-06-06 Paul D. Smith <psmith@gnu.org>
4109 * variable.c (do_variable_definition): New function: extract the
4110 part of try_variable_definition() that actually sets the value
4111 into a separate function.
4112 (try_variable_definition): Call do_variable_definition() after
4113 parsing the variable definition string.
4114 (define_variable_in_set): Make the name argument const.
4116 * variable.h (enum variable_flavor): Make public.
4117 (do_variable_definition): Create prototype.
4119 * read.c (read_all_makefiles): Create a new built-in variable,
4121 (read_makefile): Add each makefile read in to this variable value.
4123 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4125 * Makefile.DOS.template: Tweak according to changes in the
4126 distribution. Add back the dependencies of *.o files.
4128 * configh.dos.template: Synchronize with config.h.in.
4130 2002-05-09 Paul D. Smith <psmith@gnu.org>
4132 * file.c (file_timestamp_now): Use K&R function declaration.
4134 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4135 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4136 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4137 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4138 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4139 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4140 nlist.n_name is a pointer rather than an array.
4142 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4143 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4144 * configure.in: Use it instead of the old version.
4146 * main.c (main): Prefer setvbuf() to setlinebuf().
4148 2002-05-08 Paul D. Smith <psmith@gnu.org>
4150 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4151 (loadavg_LDADD): Ditto.
4153 2002-04-29 Paul D. Smith <psmith@gnu.org>
4155 * expand.c (recursively_expand_for_file): Rename
4156 recursively_expand() to recursively_expand_for_file() and provide
4157 an extra argument, struct file. If the argument is provided, set
4158 the variable scope to that of the file before expanding.
4159 * variable.h (recursively_expand): Make this a macro that invokes
4160 recursively_expand_for_file() with a NULL file pointer.
4161 * variable.c (target_environment): Call the renamed function and
4162 provide the current file context.
4163 Fixes Debian bug #144306.
4165 2002-04-28 Paul D. Smith <psmith@gnu.org>
4167 Allow $(call ...) user-defined variables to be self-referencing
4168 without throwing an error. Allows implementation of transitive
4169 closures, among other possibly useful things.
4170 Requested by: Philip Guenther <guenther@sendmail.com>
4172 * variable.h (struct variable): Add a new field: exp_count, and
4173 new macros to hold its size and maximum value.
4174 (warn_undefined): Make this a macro.
4175 * variable.c (define_variable_in_set): Initialize it.
4176 * expand.c (recursively_expand): If we detect recursive expansion
4177 of a variable, check the exp_count field. If it's greater than 0
4178 allow the recursion and decrement the count.
4179 (warn_undefined): Remove this (now a macro in variable.h).
4180 * function.c (func_call): Before we expand the user-defined
4181 function, modify its exp_count field to contain the maximum
4182 number of recursive calls we'll allow. After the call, reset it
4185 2002-04-21 Paul D. Smith <psmith@gnu.org>
4187 Modified to use latest autoconf (2.53), automake (1.6.1), and
4188 gettext (0.11.1). We're using gettext's new "external" support,
4189 to avoid including libintl source with GNU make.
4191 * README.cvs: New file. Explain how to build GNU make from CVS.
4193 * configure.in: Modify checking for the system glob library.
4194 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4195 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4196 etc. will manage it correctly). Set an automake conditional
4197 USE_LOCAL_GLOB to decide whether to compile the glob library.
4199 * getloadavg.c (main): Include make.h in the "TEST" program to
4202 * Makefile.am: Remove special rules for loadavg. Replace them
4203 with Automake capabilities for building extra programs.
4205 * signame.c: This file does nothing if the system provide
4206 strsignal(). If not, it implements strsignal(). If the system
4207 doesn't define sys_siglist, then we make our own; otherwise we use
4209 * signame.h: Removed.
4211 * main.c (main): No need to invoke signame_init(). Update copyright.
4213 * ABOUT-NLS: Removed.
4214 * gettext.c: Removed.
4215 * gettext.h: Get a simplified copy from the gettext package.
4217 * i18n/*.po: Moved to po/.
4220 * config/*: Created. Contains package configuration helper files.
4221 * config.guess, config.sub: Moved to config directory.
4223 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4224 Rework to use new-style autoconf features. Use the "external"
4225 mode for gettext. Make the build.sh config file conditional on
4226 whether build.sh.in exists, to avoid autoconf errors.
4227 * acinclude.m4: Removed almost all macros as being obsolete.
4228 Rewrote remaining macros to use AC_DEFINE.
4229 * acconfig.h: Removed.
4231 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4232 conditional to handle customs support. Remove special handling
4235 2002-04-20 Paul D. Smith <psmith@gnu.org>
4237 * function.c (func_call): Don't mark the argument variables $1,
4238 etc. as recursive. They've already been fully expanded so
4239 there's no need to do it again, and doing so strips escaped $'s.
4240 Reported by Sebastian Glita <glseba@yahoo.com>.
4242 * remake.c (notice_finished_file): Walk through double-colon
4243 entries via the prev field, not the next field!
4244 Reported by Greg McGary <greg@mcgary.org>.
4246 * main.c (main): If the user specifies -q and asks for a specific
4247 target which is a makefile, we got an assert. In that case it
4248 turns out we should continue normally instead.
4250 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4252 * i18n/he.po: Installed a new translation.
4254 2002-01-07 Paul D. Smith <psmith@gnu.org>
4256 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4258 2001-12-04 Paul D. Smith <psmith@gnu.org>
4260 * i18n/ja.po: Installed an updated translation.
4262 2001-09-06 Paul Eggert <eggert@twinsun.com>
4264 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4265 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4267 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4269 (main): Get rid of any avoidable limit on stack size.
4271 2001-09-04 Paul D. Smith <psmith@gnu.org>
4273 * i18n/da.po: Installed an updated translation.
4275 2001-08-03 Paul D. Smith <psmith@gnu.org>
4277 * i18n/fr.po: Installed an updated translation.
4278 Resolves Debian bug #106720.
4280 2001-06-13 Paul D. Smith <psmith@gnu.org>
4282 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4285 2001-06-11 Paul D. Smith <psmith@gnu.org>
4287 * i18n/ko.po: Installed a new translation.
4289 2001-05-06 Paul D. Smith <psmith@gnu.org>
4291 Modify the EINTR handling.
4293 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4294 the way in which we manage the file descriptor/signal handler race
4295 trap to be more efficient.
4297 2001-05-06 Paul Eggert <eggert@twinsun.com>
4299 Restart almost all system calls that are interrupted, instead
4300 of worrying about EINTR. The lone exception is the read() for
4303 * configure.in (HAVE_SA_RESTART): New macro.
4304 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4305 * main.c (main): Use SA_RESTART instead of the old,
4306 nonstandard SA_INTERRUPT.
4308 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4309 * main.c (bsd_signal): New function or macro,
4310 if the implementation doesn't supply it.
4311 (The bsd_signal function will be in POSIX 1003.1-200x.)
4312 (HANDLESIG): Remove.
4313 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4315 * make.h (EINTR_SET): Remove.
4316 (SA_RESTART): New macro.
4318 * arscan.c (ar_member_touch): Don't worry about EINTR.
4319 * function.c (func_shell): Likewise.
4320 * job.c (reap_children, free_child, new_job): Likewise.
4321 * main.c (main): Likewise.
4322 * remake.c (touch_file, name_mtime): Likewise.
4324 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4325 if fstat failed with errno!=EINTR, the error was ignored.
4327 * job.c (set_child_handler_action_flags): New function.
4328 (new_job): Use it to temporarily clear the SIGCHLD action flags
4329 while reading the token.
4331 2001-05-02 Paul D. Smith <psmith@gnu.org>
4333 * job.c (start_job_command): Don't add define/endef per-line flags
4334 to the top-level flags setting.
4336 2001-04-03 Paul D. Smith <psmith@gnu.org>
4338 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4339 bit on error, so check for odd return values, not non-0 return
4341 (VMS_get_member_info): Calculate the timezone differences correctly.
4342 Reported by John Fowler <jfowler@nyx.net>.
4345 2001-03-14 Paul D. Smith <psmith@gnu.org>
4347 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4348 value before invoking define_variable().
4349 Reported by John Fowler <jfowler@nyx.net>.
4351 2001-02-07 Paul D. Smith <psmith@gnu.org>
4353 * read.c (record_target_var): If we reset the variable due to a
4354 command-line variable setting overriding it, turn off the "append"
4357 2001-01-17 Paul D. Smith <psmith@gnu.org>
4359 * variable.c (lookup_variable) [VMS]: When getting values from the
4360 environment, allocate enough space for the _value_ plus escapes,
4361 not enough space for the name plus escapes :-/.
4362 Reported by John Fowler <jfowler@nyx.net>.
4364 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4365 warnings that make generates, so it doesn't look like an error.
4366 Reported by Karl Berry <karl@gnu.org>.
4369 Fix for PR/2020: Rework appended target-specific variables. I'm
4370 fairly confident this algorithm is finally correct.
4372 * expand.c (allocated_variable_append): Rewrite. Instead of
4373 expanding each appended variable then adding all the expanded
4374 strings together, we append all the unexpanded values going up
4375 through the variable set contexts, then expand the final result.
4376 This behaves just like non-target-specific appended variable
4377 values, while the old way didn't in various corner cases.
4378 (variable_append): New function: recursively append the unexpanded
4379 value of a variable, walking from the outermost variable scope to
4381 * variable.c (lookup_variable): Remove the code that looked up the
4382 variable set list if the found variable was "append". We don't
4384 (lookup_variable_in_set): Make this non-static so we can use it
4386 (try_variable_definition): Use lookup_variable_in_set() rather
4387 than faking out current_variable_set_list by hand (cleanup).
4388 * variable.h: Add a prototype for the now non-static
4389 lookup_variable_in_set().
4391 2000-11-17 Paul D. Smith <psmith@gnu.org>
4393 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4394 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4395 before throwing a fit.
4397 2000-11-17 Paul D. Smith <psmith@gnu.org>
4399 * read.c (readline): CRLF calculations had a hole, if you hit the
4400 buffer grow scenario just right. Reworked the algorithm to avoid
4401 the need for len or lastlen at all. Problem description with
4402 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4404 2000-10-24 Paul D. Smith <psmith@gnu.org>
4406 * gettext.c (SWAP): Declare this with the prototype, otherwise
4407 some systems don't work (non-32-bit? Reported for Cray T3E).
4408 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4410 2000-10-05 Paul D. Smith <psmith@gnu.org>
4412 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4413 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4415 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4417 2000-09-22 Paul D. Smith <psmith@gnu.org>
4419 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4420 parts of the real gettext.h here, and we expect to really include
4421 the real gettext.h later. If we keep this #define, it's ignored.
4423 2000-09-21 Paul D. Smith <psmith@gnu.org>
4425 * main.c (log_working_directory): Rework the text to use complete
4426 sentences, to make life simpler for the translators.
4428 2000-08-29 Paul D. Smith <psmith@gnu.org>
4430 * file.c (remove_intermediates): Print a debug message before we
4431 remove intermediate files, so the user (if she uses -d) knows
4434 2000-08-21 Paul D. Smith <psmith@gnu.org>
4436 * variable.c (try_variable_definition): Change how we handle
4437 target-specific append variable defns: instead of just setting the
4438 value, expand it as an append _but_ only within the current
4439 target's context. Otherwise we lose all but the last value if the
4440 variable is appended more than once within the current target
4441 context. Fixes PR/1831.
4443 2000-08-16 Paul D. Smith <psmith@gnu.org>
4445 * function.c (func_shell): Nul-terminate the buffer before
4446 printing an exec error message (just in case it's not!).
4447 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4449 2000-07-25 Paul D. Smith <psmith@gnu.org>
4451 * job.c (construct_command_argv_internal): Add "~" to the list of
4452 sh_chars[] which disallow optimizing out the shell call.
4454 2000-07-23 Paul Eggert <eggert@twinsun.com>
4456 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4457 supersedes --disable-nsec-timestamps.
4458 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4459 * README: Remove --disable-nsec-timestamps.
4461 * filedef.h (struct file.low_resolution_time): New member.
4462 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4463 * remake.c (update_file_1):
4464 Avoid spurious rebuilds due to low resolution time stamps,
4465 generalizing the earlier code that applied only to archive members.
4466 (f_mtime): Archive members always have low resolution time stamps.
4468 * configure.in: Remove --disable-nsec-timestamps, as this has
4469 been superseded by .LOW_RESOLUTION_TIME.
4471 2000-07-23 Paul Eggert <eggert@twinsun.com>
4473 * configure.in (enable_nsec_timestamps): Renamed from
4474 make_cv_nsec_timestamps, since enable/disable options
4475 shouldn't be cached.
4477 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4478 and Paul Eggert <eggert@twinsun.com>
4480 * file.c (file_timestamp_now):
4481 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4482 so that clock_gettime is not linked unless needed.
4484 * filedef.h (FILE_TIMESTAMP_HI_RES):
4485 Remove definition; "configure" now does this.
4487 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4488 to before high resolution file timestamp check,
4489 since that check now uses uintmax_t.
4490 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4491 high resolution file timestamps.
4492 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4493 so that we don't link in clock_gettime unnecessarily.
4495 2000-07-17 Paul D. Smith <psmith@gnu.org>
4497 * i18n/ja.po: New version of the translation file.
4499 2000-07-07 Paul D. Smith <psmith@gnu.org>
4501 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4502 the offset calculation.
4503 (name_mtime): Replace EINTR test with EINTR_SET macro.
4505 2000-07-07 Paul Eggert <eggert@twinsun.com>
4509 * remake.c (update_file_1):
4510 Avoid spurious rebuilds of archive members due to their
4511 timestamp resolution being only one second.
4512 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4513 the clock's resolution being lower than file timestamps'.
4514 When warning about future timestamps, report only the discrepancy,
4515 not the absolute value of the timestamp and the current time.
4517 * file.c (file_timestamp_now): New arg RESOLUTION.
4518 * filedef.h (file_timestamp_now): Likewise.
4519 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4521 2000-07-05 Paul D. Smith <psmith@gnu.org>
4523 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4524 to listp. Fixes PR/1793.
4526 2000-06-26 Paul Eggert <eggert@twinsun.com>
4528 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4530 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4532 * remake.c (f_mtime): Remove unused var memtime.
4534 2000-06-25 Martin Buchholz <martin@xemacs.org>
4536 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4537 Ran spell-check on make.texinfo.
4539 2000-06-23 Paul D. Smith <psmith@gnu.org>
4541 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4542 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4543 * make.h: Define these macros.
4545 * Version 3.79.1 released.
4547 * configure.in: Add a new option, --disable-nsec-timestamps, to
4548 avoid using sub-second timestamps on systems that support it. It
4549 can lead to problems, e.g. if your makefile relies on "cp -p".
4550 * README.template: Document the issue with "cp -p".
4552 * config.guess, config.sub: Updated.
