673 2010-07-01 Paul Smith <psmith@gnu.org>
675 * main.c (main): Append optional features using separate calls.

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

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

832 2009-10-03 Paul Smith <psmith@gnu.org>
834 * make.h: Include <alloca.h> even on systems where __GNUC__ is

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

920 (mostlyclean-recursive, clean-recursive, distclean-recursive)
921 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
922 (tags-recursive): Allow for more than one subdir in the build
924 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
925 targets. Enter into doc/ to produce the targets.
926 (all-am): $(INFO_DEPS) replaced by info.
928 2009-09-26 Paul Smith <psmith@gnu.org>
930 * read.c (record_files): Use free_ns() to free struct nameseq.
933 * rule.c (freerule): Use free_dep_chain().
935 * read.c (record_files): Free FILENAMES chain for implicit rules.
936 (eval): Static pattern targets go into the string cache.
938 * function.c (string_glob): Free NAME in the nameseq chain.
940 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
942 * implicit.c (pattern_search): Terminate early if we haven't
943 found any rules to try (performance improvement).
945 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
947 * implicit.c (pattern_search): Merge three parallel arrays,
948 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
949 of struct TRYRULE. In the old version the latter two arrays
950 had insufficient length.
952 2009-09-24 Paul Smith <psmith@gnu.org>
954 * implicit.c (pattern_search): Add back support for order-only
955 prerequisites for secondary expansion implicit rules, that were
956 accidentally dropped. If we find a "|", enable order-only mode
957 and set IGNORE_MTIME on all deps that are seen afterward.
958 (pattern_search): Fix memory leaks: for intermediate files where
959 we've already set the file variable and pattern variable sets, be
960 sure to either save or free them as appropriate.
962 2009-09-23 Paul Smith <psmith@gnu.org>
964 Rework the way secondary expansion is stored, for efficiency.
965 This changes secondary expansion so that ONLY WHEN we know we have
966 a possibility of needing secondary expansion, do we defer the
967 secondary expansion. This means more parsing the deps but we use
968 a lot less memory (due to the strcache). Also, this fixes
971 * read.c (eval): Don't parse the dep string here anymore.
972 (record_files): Take the dep argument as an unparsed string. If
973 secondary expansion is enabled AND the prereq string has a '$' in
974 it, then set NEED_2ND_EXPANSION and keep the entire string.
975 Otherwise, parse the dep string here to construct the dep list
976 with the names in the strcache.
978 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
979 duplicate the name string (others are in the strcache).
981 * implicit.c: Remove struct idep and free_idep_chain(): unused.
982 (struct patdeps): New structure to store prereq information.
983 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
984 which prerequisites need expansion, and expand only those.
986 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
987 and enter_prereqs(). split_prereqs() takes a fully-expanded string
988 and splits it into a DEP list, handling order-only prereqs.
989 (enter_prereqs): This function enters a list of DEPs into the file
990 database. If there's a stem defined, expand any pattern chars.
991 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
992 set. Use the above functions.
993 (snap_deps): Only perform second expansion on prereqs that need it,
994 as defined by the NEED_2ND_EXPANSION flag.
995 (print_prereqs): New function to print the prereqs
996 (print_file): Call print_prereqs() rather than print inline.
998 * hash.h (STRING_COMPARE): Take advantage of strcache() by
1000 (STRING_N_COMPARE): Ditto.
1001 (ISTRING_COMPARE): Ditto.
1003 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
1004 (parse_file_seq): Return void*
1005 * read.c (parse_file_seq): Return void*.
1006 (eval): Invoke macroized version of parse_file_seq()
1007 * default.c (set_default_suffixes): Ditto.
1008 * file.c (split_prereqs): Ditto.
1009 * function.c (string_glob): Ditto.
1010 * main.c (main): Ditto.
1011 * rule.c (install_pattern_rule): Ditto.
1013 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
1015 2009-09-16 Paul Smith <psmith@gnu.org>
1017 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
1019 * dep.h: Create alloc_dep() / free_dep() macros.
1021 * implicit.c (pattern_search): Take advantage of the new
1022 parse_file_seq() to add the directory prefix to each prereq.
1024 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
1025 all. Avoid reversing chains. Support adding prefixes.
1026 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
1027 cached/non-cached results.
1028 (eval): Remove multi_glob() & invoke new parse_file_seq().
1029 * rule.c (install_pattern_rule): Ditto.
1030 * main.c (main): Ditto.
1031 * implicit.c (pattern_search): Ditto.
1032 * function.c (string_glob): Ditto.
1033 * file.c (parse_prereqs): Ditto.
1034 * default.c (set_default_suffixes): Ditto.
1036 * variable.c (parse_variable_definition): Don't run off the end of
1037 the string if it ends in whitespace (found with valgrind).
1039 * commands.c (set_file_variables): Keep space for all targets in
1040 $? if -B is given (found with valgrind).
1042 2009-09-15 Paul Smith <psmith@gnu.org>
1044 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
1045 (xcalloc): Add new function.
1046 * make.h: New declarations.
1048 * ar.c (ar_glob_match): New calling method for concat().
1049 * main.c (main): Ditto.

1051 * read.c (eval_makefile): Ditto.
1052 (tilde_expand): Ditto.
1053 (parse_file_seq): Ditto.
1054 * variable.c (target_environment): Ditto.
1055 (sync_Path_environment): Ditto.
1057 * ar.c (ar_glob_match): Use xcalloc().
1058 * dir.c (file_impossible): Ditto.
1059 * file.c (enter_file): Ditto.
1060 * job.c (new_job): Ditto.
1061 * read.c (parse_file_seq): Ditto.
1062 * vmsfunctions.c (opendir): Ditto.
1064 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
1066 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
1067 inside the loop that looks up environment for PATH.
1069 2009-08-31 Eli Zaretskii <eliz@gnu.org>
1071 * function.c (windows32_openpipe): Update envp after calling
1072 sync_Path_environment.
1074 2009-08-02 Paul Smith <psmith@gnu.org>
1076 * remake.c (notice_finished_file): Ensure file->cmds is not null
1077 before looping through them. Fixes Savannah bug #21824.
1079 * doc/make.texi (Wildcard Examples): Clarify when objects is
1080 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1081 (Include): Clarify the behavior of -include.
1082 Fixes Savannah bug #18963.
1084 2009-08-01 Paul Smith <psmith@gnu.org>
1086 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1087 etc. come on the command line. Fixes Savannah bug #27093.
1089 * expand.c (expand_argument): If the argument is large enough use
1090 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1092 * variable.c (do_variable_definition): Avoid using alloca() to
1093 hold values, which can be large. Fixes Savannah bug #23960.
1095 * job.c (new_job): Use memmove() instead of strcpy() since both
1096 pointers are in the same memory block. Fixes Savannah bug #27148.
1097 Patch by Petr Machata.
1099 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1101 * job.c (construct_command_argv_internal): Add "ulimit" and
1102 "unset" to the sh_cmds for Unixy shells.
1104 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1106 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1107 that set make_cv_sys_gnu_glob, so they are also correctly set
1108 when the cache has been populated before.
1110 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1112 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1113 exist, as realpath(3) does where it's supported.
1115 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1117 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1118 (abspath): Support systems that define HAVE_DOS_PATHS (have
1119 drive letters in their file names). Use IS_PATHSEP instead of a
1120 literal '/' comparison. Fixes Savannah bug #26886.
1122 2009-06-14 Paul Smith <psmith@gnu.org>
1124 * remake.c (update_file_1): Remember the original file we marked
1125 as updating, so we can clear that flag again. If we find a target
1126 via vpath, FILE might change.
1127 (check_dep): Ditto. Fixes Savannah bug #13529.
1128 Patch by Reid Madsen <reid.madsen@tek.com>.
1130 2009-06-13 Paul Smith <psmith@gnu.org>
1132 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1133 included by MAKEFILES cannot give default goals.
1134 * read.c (eval): If set_default is not set, pass the no-default-goal
1135 value when we read included makefiles. Fixes Savannah bug #13401.
1137 * ar.c (ar_name): Ensure that targets with empty parens aren't
1138 considered archive member references: archive members must have a
1139 non-empty "member" string. Fixes Savannah bug #18435.
1141 * function.c (string_glob): Rely on multi_glob() to determine
1142 whether files exist or not. Remove call to file_exists_p() which
1143 is not always correct. Fixes Savannah bug #21231.
1144 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1145 then only files that really exist will be returned.
1146 * dep.h: Add new argument to multi_glob().
1147 * rule.c (install_pattern_rule): Ditto.
1148 * read.c (eval): Ditto.
1149 * main.c (main): Ditto.
1150 * implicit.c (pattern_search): Ditto.
1151 * file.c (parse_prereqs): Ditto.
1152 * default.c (set_default_suffixes): Ditto.
1154 2009-06-09 Paul Smith <psmith@gnu.org>
1156 * commands.c (set_file_variables): If always_make_flag is set,
1157 always add the prereq to $?. Fixes Savannah bug #17825.
1159 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1160 to rebuild the deps of all the also_make targets for that file.
1161 Fixes Savannah bug #19108.
1163 * implicit.c (pattern_search): Undo test for is_target, added by
1164 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1165 Rule Search Algorithm". Fixes Savannah bug #17752.
1167 * main.c (clean_jobserver): Clear the jobserver_fds options and
1168 set job_slots to the default when we clean up.
1169 (define_makeflags): Return the new MAKEFLAGS value.
1170 (main): Reset MAKEFLAGS in the environment when we re-exec.
1171 Fixes Savannah bug #18124.
1173 2009-06-08 Paul Smith <psmith@gnu.org>
1175 * read.c (eval): Collapse continuations post-semicolon on target-
1176 specific variables. Fixes Savannah bug #17521.
1178 2009-06-07 Paul Smith <psmith@gnu.org>
1180 * job.c (reap_children): For older systems without waitpid() (are
1181 there any of these left?) run wait(2) inside EINTRLOOP to handle
1182 EINTR errors. Fixes Savannah bug #16401.
1184 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1186 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1188 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1189 not the end, to catch second expansion $(eval ...) defining new
1190 target/prereq relationships during snap_deps.
1191 Fixes Savannah bug #24622.
1193 * read.c (record_files): The second-expansion "f->updating" hack
1194 was not completely correct: if assumed that the target with
1195 commands always had prerequisites; if one didn't then the ordering
1196 was messed up. Fixed for now to use f->updating to decide whether
1197 to preserve the last element in the deps list... but this whole
1198 area of constructing and reversing the deps list is too confusing
1199 and needs to be reworked. Fixes Savannah bug #21198.
1201 2009-06-06 Paul Smith <psmith@gnu.org>
1203 * hash.c (hash_insert): Remove useless test for NULL.
1204 Fixes Savannah bug #21823.
1206 * make.h: Move SET_STACK_SIZE determination to make.h.
1207 * main.c (main): New global variable, STACK_LIMIT, holds the
1208 original stack limit when make was started.
1209 * job.c (start_job_command): Reset the stack limit, if we changed it.
1210 Fixes Savannah bug #22010.
1212 * remake.c (check_dep): Only set the target's state to not-started
1213 if it's not already running. Found this while testing -j10 builds
1214 of glibc: various targets were being rebuilt multiple times.
1215 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1218 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1219 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1222 2009-06-04 Paul Smith <psmith@gnu.org>
1224 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1226 * maintMakefile: Modify access of config and gnulib Savannah
1227 modules to use GIT instead of CVS.
1229 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1230 Fixes Savannah bug #24655.
1232 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1233 this can happen during some invocations of $(eval ...) for example.
1234 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1236 2009-06-02 Paul Smith <psmith@gnu.org>
1238 * configure.in: Check for fileno()
1239 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1240 for the makefile file so invocations of $(shell ...) don't inherit it.
1241 Fixes Savannah bug #24277.
1243 2009-06-01 Paul Smith <psmith@gnu.org>
1245 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1246 expansion was handled incorrectly. Rework the default goal
1247 handling to save the variable only. Remove default_goal_file and
1249 * read.c (eval): Check default_goal_var, not default_goal_name.
1250 * read.c (record_target_var): Don't check default_goal_file here.
1252 2009-05-31 Paul Smith <psmith@gnu.org>
1254 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1255 it, and if the multi_glob() returns nothing (say it expanded to
1256 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1258 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1259 $(and ..) to the reference. Fixes Savannah bug #25694.
1261 * make.1: Be clear that some recipes will be executed even with -n.
1262 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1264 * doc/make.texi (Override Directive): Make more clear how
1265 overrides and appends interact.
1266 Elucidates part of Savannah bug #26207.
1268 * read.c (record_target_var): Don't reset the origin on
1269 target-specific variables; try_variable_definition() will handle
1270 this correctly. Fixes Savannah bug #26207.
1272 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1273 Fixes Savannah bug #25712.
1275 * implicit.c (pattern_search): Keep a pointer to the beginning of
1276 the filename and save that instead of the constructed pointer.
1277 Fixes Savannah bug #26593.
1278 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1280 2009-05-30 Paul Smith <psmith@gnu.org>
1282 * doc/make.texi (Multi-Line): Add a description of the new abilities
1283 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1284 "command sequence" vs. "recipe" syntax.
1285 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1286 after a define, to create variables with those flavors.
1288 2009-05-25 Paul Smith <psmith@gnu.org>
1290 Reworked the parser for variable assignments to allow multiple
1291 modifiers, and in any order. Also allows variable and
1292 prerequisites to be modifier names ('export', 'private', etc.)
1294 * NEWS: Add notes about user-visible changes.
1296 * read.c (struct vmodifiers): Remember what modifiers were seen.
1297 (parse_var_assignment): New function to parse variable assignments.
1298 (eval): Call the new function. Handle variable assignments earlier.
1300 * variable.c (parse_variable_definition): Only parse; don't create var.
1301 (assign_variable_definition): Call parse, then create the var.
1303 2009-05-24 Paul Smith <psmith@gnu.org>
1305 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1306 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1308 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1310 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1311 Fixes Savannah bug #25412.
1313 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1314 prototype for xmalloc.
1315 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1316 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1317 Loop over an array of extensions, instead of duplicating the same
1318 code inline. Use SearchPath followed by CreateFile, instead of
1319 the obsolete OpenFile. Fixes Savannah bug #17277.
1320 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1321 to `find_file'. Fixes Savannah bug #25662.
1323 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1325 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1326 Fixes Savannah bug #20495.
1328 2009-02-28 Ralf Wildenhues <address@hidden>
1330 * doc/make.texi (Instead of Execution): Document interaction of
1331 -t with phony targets.
1333 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1335 Introduce a new keyword "private" which applies to target-specific
1336 variables and prevents their values from being inherited.
1338 * variable.h (struct variable): Add private_var flag to each variable.
1339 Add a flag to specify which list entry switches to the parent target.
1340 * variable.c (define_variable_in_set): Initialize private_var flag.

1353 * make.h: Rename savestring to xstrndup.
1354 * commands.c (chop_commands): Ditto.
1355 * function.c (func_foreach): Ditto.
1356 * read.c (eval, record_files): Ditto.
1357 * variable.c (define_variable_in_set): Ditto.
1359 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1361 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1364 * w32/subproc/build.bat (GCCBuild): Likewise.
1366 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1368 * job.c (construct_command_argv_internal): Avoid extra backslash
1369 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1372 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1374 * README.W32.template: Remove obsolete text about non-support for
1375 -jN without Unixy shell. Remove obsolete text about not supplying
1376 Visual Studio project files (we do supply them). Modify text to
1377 prefer GCC builds to MSC builds.
1379 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1381 * doc/make.texi (Empty Targets): Fix typo.
1383 2008-03-27 Paul Smith <psmith@gnu.org>

1396 `value' field is NULL.
1398 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1400 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1402 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1403 (TEXINFOS): Value changed to `doc/make.texi'.
1404 (.SUFFIXES): Use .texi instead of .texinfo.
1405 (make.info, make.dvi): Depend on doc/make.texi.
1406 (.texi.info): New target, instead of ".texinfo.info". Change -I
1407 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1408 (.texi): New target, instead of ".texinfo". Change -I switch to
1409 $(MAKEINFO) to look in doc/. Use --no-split.
1410 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1411 switch to $(MAKEINFO) to look in doc/.
1412 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1413 "*.i[0-9][0-9]" (due to --no-split above).

1415 (html, make_1.html): New targets.
1416 (.PHONY): Add "html".

1422 HAVE_DECL_SYS_SIGLIST.
1424 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1425 build does not use child_execute_job.
1427 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1428 export the SHELL environment variable to the child.
1430 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1432 * config.h.W32: Include sys/types.h.

1449 * remake.c (f_mtime): Print time difference values between 100 and
1450 ULONG_MAX in fixed-point notation rather than in exponention notation.
1452 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1454 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1455 a more complex value than a simple shell: if it's not a default
1456 shell now then expand it and see if is a default shell then.
1458 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1460 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1461 pathnames, with const strings.
1462 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1463 from the template (used for building from CVS, not a dist).
1465 2007-10-10 Paul Smith <psmith@gnu.org>
1467 * make.h: Add a prototype for w32_kill() (change suggested by
1468 Yongwei Wu <wuyongwei@gmail.com>).
1470 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1472 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1473 directories in Path.
1475 2007-09-12 Paul Smith <psmith@gnu.org>

1478 Provided by Diego Biurrun <diego@biurrun.de>
1479 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1480 Provided by Diego Biurrun <diego@biurrun.de>
1482 2007-09-11 Paul Smith <psmith@gnu.org>
1484 * doc/make.texi (Special Variables): Moved this into the "How to
1485 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1486 (MAKEFILE_LIST) No longer a section; this was added into the
1487 "Special Variables" section.
1488 (Rule Introduction): Reference .RECIPEPREFIX.
1489 (Simple Makefile): Ditto.
1490 (Rule Syntax): Ditto.
1491 (Command Syntax): Ditto.
1492 (Error Messages): Ditto.
1494 2007-09-10 Paul Smith <psmith@gnu.org>
1496 * commands.c (print_commands): Don't print an extra line in the
1497 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1499 * read.c (construct_include_path): Add the full string to the cache; we
1500 were chopping the last char.
1502 * NEWS: Announce the .RECIPEPREFIX special variable.
1503 * variable.c (lookup_special_var): Rename from handle_special_var().
1504 (lookup_variable): Call the new name.
1505 (set_special_var): New function: handle setting of special variables.
1506 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1507 (do_variable_definition): Call it.
1508 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1509 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1510 * main.c (main): Create the .RECIPEPREFIX special variable.
1511 * read.c (eval): Remove the cmd_prefix characters from the command
1512 scripts here, so they're not stored in the commands array at all,
1513 rather than waiting and stripping them out during command construction.
1514 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1516 2007-08-15 Paul Smith <psmith@gnu.org>
1518 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1519 file has had the section info removed, so add some to make.texi
1520 before we include it.
1522 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1524 * remake.c (check_dep): Reset the target state for intermediate
1525 files. They might have been considered before but not updated
1526 then (order-only for example) but they will be this time.
1527 Fixes Savannah bug #'s 3330 and 15919.
1529 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1531 Fix Savannah bug #20549:
1532 * function.c (func_shell): Call construct_command_argv with zero
1534 * job.c (construct_command_argv_internal): New argument FLAGS; all
1536 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1538 * job.h (construct_command_argv_internal): Update prototype.
1540 2007-07-13 Paul Smith <psmith@gnu.org>
1542 * file.c (expand_deps): Use variable_buffer as the start of the
1543 buffer, not the original pointer (in case it was reallocated).
1544 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1545 Fixes Savannah bug #20452.
1547 2007-07-04 Paul Smith <psmith@gnu.org>
1549 * (ALL FILES): Update to GPLv3.
1550 * (ALL FILES): Update copyright for 2007.

1554 2007-06-29 Thiemo Seufer <ths@mips.com>
1556 * maintMakefile: Update Translation Project location.
1558 2007-06-13 Paul Smith <psmith@gnu.org>
1560 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1561 "Expansion of a deferred"
1562 Fixes Savannah bug #20018.
1564 * expand.c (variable_expand_for_file): Preserve the value of
1565 reading_file rather than setting it to 0 at the end.
1566 Fixes Savannah bug #20033.
1568 2007-05-11 Paul Smith <psmith@gnu.org>
1570 * job.c (new_job): Add debug info to specify where make found the
1571 command script it is running to build a target.
1572 Fixes Savannah bug #18617.
1574 * default.c (default_suffixes,default_suffix_rules,default_variables):

1582 Dave Korn <dave.korn@artimi.com>
1584 2007-05-08 Paul Smith <psmith@gnu.org>
1586 Fix Savannah bug #19656:
1588 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1590 * make.h: Change all case-insensitive string compares to use
1591 strcasecmp() (from POSIX). If we don't have that but do have one
1592 of the others, define strcasecmp to be one of those instead. If
1593 we don't have any, declare a prototype for our own version.
1595 * misc.c (strcasecmp): Use this if we can't find any native
1596 case-insensitive string comparison function.
1597 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1598 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1600 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1601 strcasecmp() instead of stricmp().
1602 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1603 instead of strcmpi().
1604 * acinclude.m4: Remove the strcasecmp() check from here.
1606 2007-03-21 Paul Smith <psmith@gnu.org>
1608 * configure.in: Don't turn on case-insensitive file system support
1609 if --disable-... is given. Fixes Savannah bug #19348.
1611 2007-03-19 Paul Smith <psmith@gnu.org>
1613 * ALL: Use the strcache for all file name strings, or other
1614 strings which we will never free. The goal is to save memory by
1615 avoiding duplicate copies of strings. However, at the moment this
1616 doesn't save much memory in most situations: due to secondary
1617 expansion we actually save prerequisite lists twice (once before
1618 the secondary expansion, and then again after it's been parsed
1619 into individual file names in the dep list). We will resolve this
1620 in a future change, by doing the parsing up-front for targets
1621 where secondary expansion is not set.
1623 Moving things into the strcache also allows us to use const
1624 pointers in many more places.
1626 2007-01-03 Paul Smith <psmith@gnu.org>
1628 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1629 the function, not just the first. Fixes Savannah bug #18680.
1631 2006-11-18 Paul Smith <psmith@gnu.org>
1633 * strcache.c (strcache_add_len): Don't allocate a new buffer
1634 unless the string is not already nil-terminated. Technically this
1635 is a violation of the standard, since we may be passed an array
1636 that is not long enough to test one past. However, in make this
1637 is never true since we only use nil-terminated strings or
1638 sub-strings thereof.
1640 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1642 * main.c: New global cmd_prefix, defaults to '\t'.
1643 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1646 * dir.c: Constified.
1647 (dir_contents_file_exists_p): Check for an error return from
1648 readdir(), just in case.
1650 * commands.c: Constified.
1651 * default.c: Constified.
1652 * expand.c: Constified.
1653 * function.c: Partial constification.

1658 * w32/pathstuff.c: Partial constification.
1660 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1662 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1663 backslashes and drive letters as absolute.
1665 2006-10-22 Paul Smith <psmith@gnu.org>

1669 2006-10-21 Paul Smith <psmith@gnu.org>
1672 * arscan.c: Constified.
1674 2006-09-30 Paul Smith <psmith@gnu.org>
1676 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1677 point to lastword since the example was updated.
1678 Fixes Savannah bug #16304.
1679 (Secondary Expansion): Correct example description.
1680 Fixes Savannah bug #16468.
1681 (Makefile Contents): Clarify that comments cannot appear within
1682 variable references or function calls.
1683 Fixes Savannah bug #16577.
1684 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1685 Fixes Savannah bug #17701.
1686 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1688 prerequisites. Fixes Savannah bug #17880.
1689 (Rule Syntax): "lise" -> "list"
1690 (Multiple Rules): ... -> @dots{}
1691 (Splitting Lines): ditto.
1693 * remake.c (update_file_1): Prereqs that don't exist should be
1694 considered changed, for the purposes of $?.
1695 Fixes Savannah bug #16051.

1737 that don't have extended grep.
1738 (cvsclean): Use $(PERL) instead of perl.

1742 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1744 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1745 inner-scope variables don't mask outer-scope variables.

1806 Declare and define sh_chars_sh[].
1808 2006-03-23 Paul D. Smith <psmith@gnu.org>
1810 * configure.in: Look for build.sh.in in $srcdir so it will be
1811 built for remote configurations as well.
1813 * Makefile.am: Make sure to clean up build.sh during distclean.
1814 Fixes Savannah bug #16166.
1816 * misc.c (log_access): Takes a const char *.

1818 Both fixes for Savannah bug #16170.
1820 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1822 * implicit.c (pattern_search): Call set_file_variables only
1823 if we have prerequisites that need second expansion. Fixes
1824 Savannah bug #16140.
1826 2006-03-19 Paul D. Smith <psmith@gnu.org>
1828 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1829 memory on hosts that don't support it directly.

1832 make sure I don't forget any).
1834 * main.c (clean_jobserver): Move jobserver cleanup code into a new

1844 allow multiple concurrent runs.
1845 Patch from Joseph Myers <joseph@codesourcery.com>
1847 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1849 * dep.h (struct dep): Add the stem field.
1850 * misc.c (alloc_dep, free_dep): New functions.
1851 (copy_dep_chain): Copy stem.
1852 (free_dep_chain): Use free_dep.
1853 * read.c (record_files): Store stem in the dependency line.
1854 * file.c (expand_deps): Use stem stored in the dependency line. Use
1855 free_dep_chain instead of free_ns_chain.
1856 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1857 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.

1868 Fixes Savannah bug #15913.
1870 2006-03-09 Paul Smith <psmith@gnu.org>
1872 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1873 listed non-existent files as changed. Turns out there's a bug in
1874 the Linux kernel builds which means that this change causes
1875 everything to rebuild every time. We will re-introduce this fix
1876 in the next release, to give them time to fix their build system.
1877 Fixes Savannah bug #16002.
1878 Introduces Savannah bug #16051.

1895 2006-02-19 Paul D. Smith <psmith@gnu.org>
1897 * commands.c (set_file_variables): Realloc, not malloc, the static
1898 string values to avoid memory leaks.
1900 * expand.c (recursively_expand_for_file): Only set reading_file to
1901 an initialized value.
1903 * implicit.c (pattern_search): We need to make a copy of the stem
1904 if we get it from an intermediate dep, since those get freed.
1906 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1908 (enter_file) [VMS]: Ditto.

1913 * job.c (construct_command_argv_internal): Fix last change.
1915 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1916 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1917 the calls to _beginthreadex.
1919 * expand.c (recursively_expand_for_file): Initialize `save' to
1920 prevent compiler warnings.
1922 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1924 * job.c (construct_command_argv_internal): Don't create a temporary
1925 script/batch file if we are under -n. Call _setmode to switch the
1926 script file stream to text mode.

1930 * variable.c (merge_variable_set_lists): Don't try to merge the
1931 global_setlist. Not only is this useless, but it can lead to
1932 circularities in the linked list, if global_setlist->next in one
1933 list gets set to point to another list which also ends in

1937 2006-02-15 Paul D. Smith <psmith@gnu.org>
1939 Fix for Savannah bug #106.
1941 * expand.c (expanding_var): Keep track of which variable we're
1942 expanding. If no variable is being expanded, it's the same as
1944 * make.h (expanding_var): Declare it.
1945 * expand.c (recursively_expand_for_file): Set expanding_var to the
1946 current variable we're expanding, unless there's no file info in
1947 it (could happen if it comes from the command line or a default
1948 variable). Restore it before we exit.

1960 * read.c (eval): Even if the included filenames expands to the
1961 empty string we still need to free the allocated buffer.
1963 * implicit.c (pattern_search): If we allocated a variable set for
1964 an impossible file, free it.
1965 * variable.c (free_variable_set): New function.
1966 * variable.h: Declare it.
1968 * read.c (read_all_makefiles): Makefile names are kept in the
1969 strcache, so there's never any need to alloc/free them.
1972 * main.c (main): Add "archives" to the .FEATURES variable if
1973 archive support is enabled.
1974 * doc/make.texi (Special Variables): Document it.
1976 2006-02-13 Paul D. Smith <psmith@gnu.org>

1984 * (ALL FILES): Updated copyright and license notices.
1986 2006-02-10 Paul D. Smith <psmith@gnu.org>
1988 A new internal capability: the string cache is a read-only cache
1989 of strings, with a hash table interface for fast lookup. Nothing
1990 in the cache will ever be freed, so there's no need for reference
1991 counting, etc. This is the beginning of a full solution for
1992 Savannah bug #15182, but for now we only store makefile names here.
1994 * strcache.c: New file. Implement a read-only string cache.
1995 * make.h: Add prototypes for new functions.
1996 * main.c (initialize_global_hash_tables): Initialize the string cache.
1997 (print_data_base): Print string cache stats.
1998 * read.c (eval_makefile): Use the string cache to store makefile
1999 names. Rewrite the string allocation to be sure we free everything.

2003 * dir.c (dir_contents_file_exists_p): Don't opendir if the
2004 directory time stamp didn't change, except on FAT filesystems.

2029 -W, don't overwrite it with the real mtime.

2048 * filedef.h (struct file): Add a new LAST pointer.
2050 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
2051 the comparison. For 64-bits systems the result of the subtraction
2052 might not fit into an int. Use comparison instead.
2053 Fixes Savannah bug #15534.
2055 * doc/make.texi: Update the chapter on writing commands to reflect
2056 the changes made in 3.81 for backslash/newline and SHELL handling.
2058 2006-02-01 Paul D. Smith <psmith@gnu.org>
2060 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
2061 variable st is not used when it's not initialized.

2076 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2078 * remake.c (update_goal_chain): Set g->changed instead of
2079 incrementing it, as it is only 8-bit wide, and could overflow if

2093 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
2094 are already more children than sub_proc.c can handle, behave as if
2095 the load were too high.
2096 (start_job_command): Fix a typo in error message when process_easy
2099 2006-01-14 Eli Zaretskii <eliz@gnu.org>
2101 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
2102 the shell is not sh.exe.
2104 * job.c (create_batch_file): Renamed from create_batch_filename;
2105 all callers changed. Don't close the temporary file; return its
2106 file descriptor instead. New arg FD allows to return the file
2108 (construct_command_argv_internal): Use _fdopen instead of fopen to
2109 open the batch file.
2111 2006-01-04 Paul D. Smith <psmith@gnu.org>
2113 * readme.vms: Updates for case-insensitive VMS file systems from
2114 Hartmut Becker <Hartmut.Becker@hp.com>.
2115 * dir.c (vms_hash): Ditto.
2116 * vmsify.c (copyto): Ditto.
2117 * vmsfunctions.c (readdir): Ditto.
2119 * make.1: Add a section on the exit codes for make.
2121 * doc/make.texi: A number of minor updates to the documentation.
2123 2006-01-03 Paul D. Smith <psmith@gnu.org>
2125 * remake.c (update_file_1): Mark a prerequisite changed if it
2128 * read.c (eval): Be sure to strip off trailing whitespace from the
2129 prerequisites list properly. Also, initialize all fields in
2130 struct dep when creating a new one.
2132 2005-12-28 Paul D. Smith <psmith@gnu.org>
2134 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2135 disable warnings for MSC.
2136 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2138 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2140 * doc/make.texi (Execution): Add a footnote about changes in
2141 handling of backslash-newline sequences. Mention the differences
2142 on MS-DOS and MS-Windows.
2144 * NEWS: More details about building the MinGW port and a pointer
2145 to README.W32. Fix the section name that describes the new
2146 backward-incompatible processing of backslash-newline sequences.
2147 The special processing of SHELL set to "cmd" is only relevant to
2148 MS-Windows, not MS-DOS.
2150 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2152 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2153 to DWORD, to avoid compiler warnings.
2154 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2155 use %ld in format, to avoid compiler warnings.
2157 * doc/make.texi (Special Targets): Fix a typo.
2158 (Appending): Fix cross-reference to Setting.
2159 (Special Variables, Secondary Expansion, File Name Functions)
2160 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2161 periods after a sentence.
2162 (Execution): Add @: after "e.g.".
2163 (Environment): Fix punctuation.
2164 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2165 (Shell Function, Target-specific): Add @: after "vs."
2167 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2169 * read.c (record_target_var): Initialize variable's export field
2170 with v_default instead of leaving it "initialized" by whatever
2171 garbage happened to be on the heap.
2173 2005-12-12 Paul D. Smith <psmith@gnu.org>
2175 * make.1: Fix some display errors and document all existing options.
2176 Patch by Mike Frysinger <vapier@gentoo.org>.
2178 2005-12-11 Paul D. Smith <psmith@gnu.org>
2180 * implicit.c (pattern_search): If 2nd expansion is not set for
2181 this implicit rule, replace the pattern with the stem directly,
2182 and don't re-expand the variable list. Along with the other
2183 .SECONDEXPANSION changes below, fixes bug #13781.
2185 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2187 * implicit.c (pattern_search): Mark other files that this rule
2188 builds as targets so that they are not treated as intermediates
2189 by the pattern rule search algorithm. Fixes bug #13022.
2191 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2193 * remake.c (notice_finished_file): Propagate the change of
2194 modification time to all the double-colon entries only if
2195 it is the last one to be updated. Fixes bug #14334.
2197 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2199 * function.c (func_flavor): Implement the flavor function which
2200 returns the flavor of a variable.
2201 * doc/make.texi (Functions for Transforming Text): Document it.
2202 * NEWS: Add it to the list of new functions.
2204 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2206 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2208 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2209 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2211 2005-10-26 Paul Smith <psmith@gnu.org>
2213 * read.c (record_files): Don't set deps flags if there are no deps.
2214 * maintMakefile: We only need to build the templates when we are
2215 creating a distribution, so don't do it for "all".
2217 2005-10-24 Paul D. Smith <psmith@gnu.org>
2219 Make secondary expansion optional: its enabled by declaring the
2220 special target .SECONDEXPANSION.
2222 * NEWS: Update information on second expansion capabilities.
2223 * doc/make.texi (Secondary Expansion): Document the
2224 .SECONDEXPANSION special target and its behavior.
2225 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2226 prerequisite list was found in a static pattern rule.
2227 (free_dep_chain): Declare a prototype.
2228 * file.c (parse_prereqs): New function: break out some complexity
2230 (expand_deps): If we aren't doing second expansion, replace % with
2231 the stem for static pattern rules. Call the new function.
2232 * filedef.h (parse_prereqs): Declare a prototype.
2233 * implicit.c (pattern_search): Initialize the new staticpattern
2235 * main.c (second_expansion): Declare a global variable to remember
2236 if the special target has been seen. Initialize the new
2237 staticpattern field for prerequisites.
2238 * make.h: Extern for second_expansion.
2239 * misc.c (free_dep_chain): New function: frees a struct dep list.
2240 * read.c (read_all_makefiles): Initialize the staticpattern field.
2241 (eval_makefile): Ditto.
2242 (record_files): Check for the .SECONDEXPANSION target and set
2243 second_expansion global if it's found.
2244 Use the new free_dep_chain() instead of doing it by hand.
2245 Set the staticpattern field for prereqs of static pattern targets.
2247 2005-10-16 Paul D. Smith <psmith@gnu.org>
2249 * main.c (main): Set CURDIR to be a file variable instead of a
2250 default, so that values of CURDIR inherited from the environment
2251 won't override the make value.
2253 2005-09-26 Paul D. Smith <psmith@gnu.org>
2255 * job.c (construct_command_argv_internal): If the line is empty
2256 remember to free the temporary argv strings.
2259 2005-09-16 Paul D. Smith <psmith@gnu.org>
2261 * job.c (start_job_command): The noerror flag is a boolean (single
2262 bit); set it appropriately.
2263 Reported by Mark Eichin <eichin@metacarta.com>
2265 2005-08-29 Paul D. Smith <psmith@gnu.org>
2267 * function.c (func_error): On Windows, output from $(info ...)
2268 seems to come in the wrong order. Try to force it with fflush().
2270 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2272 * read.c (record_files): Move code that sets stem for static
2273 pattern rules out of the if (!two_colon) condition so it is
2274 also executed for two-colon rules. Fixes Savannah bug #13881.
2276 2005-08-08 Paul D. Smith <psmith@gnu.org>
2278 * make.h: Don't test that __STDC__ is non-0. Some compilers
2279 (Windows for example) set it to 0 to denote "ISO C + extensions".
2282 2005-08-07 Paul D. Smith <psmith@gnu.org>
2284 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2285 conditional (slightly different version of a fix from Eli).
2287 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2288 If make is running in parallel without -k and two jobs die in a
2289 row, but not too close to each other, then make will quit without
2290 waiting for the rest of the jobs to die.
2292 * main.c (die): Don't reset err before calling reap_children() the
2293 second time: we still want it to be in the error condition.
2294 * job.c (reap_children): Use a static variable, rather than err,
2295 to control whether or not the error message should be printed.
2297 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2299 * w32/subproc/sub_proc.c: Include signal.h.
2300 (process_pipe_io, process_file_io): Pass a pointer to a local
2301 DWORD variable to GetExitCodeProcess. If the exit code is
2302 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2304 * job.c [WINDOWS32]: Include windows.h.
2305 (main_thread) [WINDOWS32]: New global variable.
2306 (reap_children) [WINDOWS32]: Get the handle for the main thread
2307 and store it in main_thread.
2309 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2310 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2311 doing anything else. When we are done, close the main thread
2312 handle and exit with status 130.
2314 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2316 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2319 * main.c (find_and_set_default_shell): If found a DOSish shell,
2320 set sh_found and the value of default_shell, and report the
2321 findings in debug mode.
2323 * job.c (construct_command_argv_internal): Check unixy_shell, not
2324 no_default_sh_exe, to decide whether to use Unixy or DOSish
2327 * README.W32: Update with info about the MinGW build.
2329 * build_w32.bat: Support MinGW.
2331 * w32/subproc/build.bat: Likewise.
2333 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2334 printing DWORD args.
2336 * function.c (windows32_openpipe): Fix format strings for printing
2339 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2341 (start_job_command): Fix format string for printing the result of
2343 (start_job_command) [WINDOWS32]: Do not define.
2344 (exec_command): Fix format string for printing HANDLE args.
2346 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2347 to avoid compiler warnings.
2348 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2349 (Note: some of these fixes were submitted independently by J. Grant)
2351 2005-07-30 J. Grant <jg@jguk.org>
2353 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2354 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2355 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2357 2005-07-15 Paul Smith <psmith@gnu.org>
2359 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2360 we don't have a POSIX shell, then revert to the old
2361 backslash-newline behavior (where they are stripped).
2364 2005-07-08 Paul D. Smith <psmith@gnu.org>
2366 * config.h.W32.template: Reorder to match the standard config.h,
2367 for easier comparisons.
2368 From J. Grant <jg@jguk.org>
2370 * maintMakefile: Remove .dep_segment before overwriting it, in
2371 case it's not writable or noclobber is set.
2372 * expand.c (variable_expand_string): Cast result of pointer
2373 arithmetic to avoid a warning.
2374 * main.c (switches): Add full-fledged final initializer.
2376 2005-07-06 Paul D. Smith <psmith@gnu.org>
2378 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2379 * signame.c (strsignal): If we found _sys_siglist[] or
2380 __sys_siglist[] use those instead of sys_siglist[].
2381 From Albert Chin <china@thewrittenword.com>
2383 2005-07-04 Paul D. Smith <psmith@gnu.org>
2385 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2386 globfree(); set up to use the GNU versions.
2387 From Martin Zinser <zinser@zinser.no-ip.info>
2389 2005-07-03 Paul D. Smith <psmith@gnu.org>
2391 From J. Grant <jg@jguk.org>:
2393 * README.W32.template: Update the Windows and tested MSVC versions.
2394 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2395 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2396 * build_w32.bat: Ditto.
2397 * w32/subproc/build.bat: Ditto.
2399 2005-06-28 Paul D. Smith <psmith@gnu.org>
2401 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2402 declaration was checked but not present.
2404 2005-06-27 Paul D. Smith <psmith@gnu.org>
2406 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2407 to unsigned long. Fixes Savannah bug #13550.
2409 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2410 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2411 Fixes Savannah bug #13551.
2413 2005-06-26 Paul D. Smith <psmith@gnu.org>
2415 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2416 it if ANSI_STRING is not set.
2418 2005-06-25 Paul D. Smith <psmith@gnu.org>
2420 * read.c (eval): If no filenames are passed to any of the
2421 "include" variants, don't print an error.
2422 * doc/make.texi (Include): Document this.
2423 Fixes Savannah bug #1761.
2425 * job.c (construct_command_argv_internal): Sanitize handling of
2426 backslash/newline pairs according to POSIX: that is, keep the
2427 backslash-newline in the command script, but remove a following
2428 TAB character, if present. In the fast path, make sure that the
2429 behavior matches what the shell would do both inside and outside
2430 of quotes. In the slow path, quote the backslash and put a
2431 literal newline in the string.
2432 Fixes Savannah bug #1332.
2433 * doc/make.texi (Execution): Document the new behavior and give
2435 * NEWS: Make a note of the new behavior.
2437 * make.h [WINDOWS32]: #include <direct.h>.
2438 Fixes Savannah bug #13478.
2440 * remake.c (name_mtime): If the stat() of a file fails and the -L
2441 option was given and the file is a symlink, take the best mtime of
2442 the symlink we can get as the mtime of the file and don't fail.
2443 Fixes Savannah bug #13280.
2445 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2446 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2447 inside a variable reference. Make this function static as it's
2449 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2450 parsing an unexpanded line looking for semicolons.
2451 Fixes Savannah bug #1454.
2452 * misc.c (remove_comments): Move this to read.c and make it static
2453 as it's only used there. Call find_char_unquote() with new arg.
2454 * make.h: Remove prototypes for find_char_unquote() and
2455 remove_comments() since they're static now.
2457 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2458 its export flag and obtain its value. When we need to re-exec,
2459 increment the value and add it into the environment.
2460 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2461 * NEWS: Mention MAKE_RESTARTS.
2462 * main.c (always_make_set): New variable. Change the -B option to
2463 set this one instead.
2464 (main): When checking makefiles, only set always_make_flag if
2465 always_make_set is set AND the restarts flag is 0. When building
2466 normal targets, set it IFF always_make_set is set.
2467 (main): Avoid infinite recursion with -W, too: only set what-if
2468 files to NEW before we check makefiles if we've never restarted
2469 before. If we have restarted, set what-if files to NEW _after_ we
2471 Fixes Savannah bug #7566:
2473 2005-06-17 Paul D. Smith <psmith@gnu.org>
2475 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2476 in the prerequisites list.
2478 2005-06-12 Paul D. Smith <psmith@gnu.org>
2480 Fix Savannah bug # 1328.
2482 * configure.in: Check for atexit().
2483 * misc.c (close_stdout): Test stdout to see if writes to it have
2484 failed. If so, be sure to exit with a non-0 error code. Based on
2485 code found in gnulib.
2486 * make.h: Prototype.
2487 * main.c (main): Install close_stdout() with atexit().
2489 2005-06-10 Paul D. Smith <psmith@gnu.org>
2491 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2493 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2494 headers; make vmsWaitForChildren() static; extern vmsify().
2495 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2496 Don't create child_execute_job() here (it's in vmsjobs.c).
2497 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2499 2005-06-09 Paul D. Smith <psmith@gnu.org>
2501 * variable.c (push_new_variable_scope): File variables point
2502 directly to the global_setlist variable. So, inserting a new
2503 scope in front of that has no effect on those variables: they
2504 don't go through current_variable_set_list. If we're pushing a
2505 scope and the current scope is global, push it "the other way" so
2506 that the new setlist is in the global_setlist variable, and
2507 next points to a new setlist with the global variable set.
2508 (pop_variable_scope): Properly undo a push with the new
2510 Fixes Savannah bug #11913.
2512 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2514 * job.c (reap_children): Don't die of the command failed but
2515 the dontcare flag is set. Fixes Savannah bug #13216.
2517 * implicit.c (pattern_search): When creating a target from
2518 an implicit rule match, lookup pattern target and set precious
2519 flag in a newly created target. Fixes Savannah bug #13218.
2521 2005-05-13 Paul D. Smith <psmith@gnu.org>
2523 Implement "if... else if... endif" syntax.
2525 * read.c (eval): Push all checks for conditional words ("ifeq",
2526 "else", etc.) down into the conditional_line() function.
2527 (conditional_line): Rework to allow "else if..." clause. New
2528 return value -2 for lines which are not conditionals. The
2529 ignoring flag can now also be 2, which means "already parsed a
2530 true branch". If that value is seen no other branch of this
2531 conditional can be considered true. In the else parsing if there
2532 is extra text after the else, invoke conditional_line()
2533 recursively to see if it's another conditional. If not, it's an
2534 error. If so, raise the conditional value to this level instead
2535 of creating a new conditional nesting level. Special check for
2536 "else" and "endif", which aren't allowed on the "else" line.
2537 * doc/make.texi (Conditional Syntax): Document the new syntax.
2539 2005-05-09 Paul D. Smith <psmith@gnu.org>
2541 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2542 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2543 recurses to the w32 directory, even on non-Windows systems. Use
2544 the method suggested in the automake manual.
2545 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2546 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2548 2005-05-07 Paul D. Smith <psmith@gnu.org>
2550 * main.c (die): If we're dying with a fatal error (not that a
2551 command has failed), write back any leftover tokens before we go.
2553 * job.c (set_child_handler_action_flags): If there are jobs
2554 waiting for the load to go down, set an alarm to go off in 1
2555 second. This allows us to wake up from a potentially long-lasting
2556 read() and start a new job if the load has gone down. Turn it off
2558 (job_noop): Dummy signal handler function.
2559 (new_job): Invoke it with the new semantics.
2561 * docs/make.texi: Document secondary expansion. Various cleanups
2564 2005-05-03 Paul D. Smith <psmith@gnu.org>
2566 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2567 the targets which are to ultimately be made are called "goals";
2568 see the GNU make manual. Also, MAKECMDGOALS, etc.
2570 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2571 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2572 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2574 2005-05-02 Paul D. Smith <psmith@gnu.org>
2576 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2577 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2578 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2579 functions to vmsjobs.c. #include it into jobs.c.
2581 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2582 jobserver tokens. I found that this happens when an exported
2583 recursive variable contains a $(shell ...) function reference: in
2584 this situation we could "forget" to write back a token.
2586 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2587 we have. It's not reliable to depend on the number of children in
2588 our linked list so keep a separate count.
2589 (new_job): Check jobserver_tokens rather than children &&
2590 waiting_jobs. Increment jobserver_tokens when we get one.
2591 (free_child): If jobserver_tokens is 0, internal error. If it's
2592 >1, write a token back to the jobserver pipe (we don't write a
2593 token for the "free" job). Decrement jobserver_tokens.
2595 * main.c: Add variable master_job_slots.
2596 (main): Set it to hold the number of jobs requested if we're the
2597 master process, when using the jobserver.
2598 (die): Sanity checks: first test jobserver_tokens to make sure
2599 this process isn't holding any tokens we didn't write back.
2600 Second, if master_job_slots is set count the tokens left in the
2601 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2603 2005-04-24 Paul D. Smith <psmith@gnu.org>
2605 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2606 with -l# can lose jobserver tokens, because waiting jobs are not
2607 consulted properly when checking for the "free" token.
2609 * job.c (free_child): Count waiting_jobs as having tokens.
2610 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2611 handle jobs waiting for the load to drop.
2613 2005-04-23 Paul D. Smith <psmith@gnu.org>
2615 * main.c (main): Be careful to not core if a variable setting in
2616 the environment doesn't contain an '='. This is illegal but can
2617 happen in broken setups.
2618 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2620 2005-04-12 Paul D. Smith <psmith@gnu.org>
2622 The second expansion feature causes significant slowdown. Timing
2623 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2624 read the makefile before the feature, to 11+s to do the same
2625 operations after the feature. Additionally, memory usage
2626 increased drastically. To fix this I added some intelligence that
2627 avoids the overhead of the second expansion unless it's required.
2629 * dep.h: Add a new boolean field, need_2nd_expansion.
2631 * read.c (eval): When creating the struct dep for the target,
2632 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2633 (record_files): If there's a "%" in a static pattern rule, it gets
2634 converted to "$*" so set need_2nd_expansion to 1.
2636 * file.c (expand_deps): Rework to be more efficient. Only perform
2637 initialize_file_variables(), set_file_variables(), and
2638 variable_expand_for_file() if the need_2nd_expansion is set.
2640 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2641 (pattern_search): Ditto.
2642 * main.c (handle_non_switch_argument): Ditto.
2644 * read.c (read_all_makefiles): Ditto.
2645 (eval_makefile): Ditto.
2647 2005-04-07 Paul D. Smith <psmith@gnu.org>
2649 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2650 * variable.c (sync_Path_environment): Ditto.
2651 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2653 * main.c (main): Define the .FEATURES variable.
2654 * NEWS: Announce .FEATURES.
2655 * doc/make.texi (Special Variables): Document .FEATURES.
2657 * remake.c (check_dep): If a file is .PHONY, update it even if
2658 it's marked intermediate. Fixes Savannah bug #12331.
2660 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2662 * file.c (expand_deps): Factor out the second expansion and
2663 prerequisite line parsing logic from snap_deps().
2665 * file.c (snap_deps): Use expand_deps(). Expand and parse
2666 prerequisites of the .SUFFIXES special target first. Fixes
2667 Savannah bug #12320.
2669 2005-03-13 Paul D. Smith <psmith@gnu.org>
2671 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2674 2005-03-11 Paul D. Smith <psmith@gnu.org>
2676 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2677 available, not undefined (from Earnie Boyd).
2679 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2681 * implicit.c (pattern_search): Mark an intermediate target as
2682 precious if it happened to be a prerequisite of some (other)
2683 target. Fixes Savannah bug #12267.
2685 2005-03-09 Paul D. Smith <psmith@gnu.org>
2687 * read.c (eval_makefile): Add alloca(0).
2688 (eval_buffer): Ditto.
2690 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2692 * main.c (main): Use o_file instead of o_default when defining
2693 the .DEFAULT_TARGET special variable.
2694 * read.c (eval): Use define_variable_global() instead of
2695 define_variable() when setting new value for the .DEFAULT_TARGET
2696 special variable. Fixes Savannah bug #12266.
2698 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2700 * imlicit.c (pattern_search): Mark files for which an implicit
2701 rule has been found as targets. Fixes Savannah bug #12202.
2703 2005-03-04 Paul D. Smith <psmith@gnu.org>
2706 * doc/make.texi (Automatic Variables): Document $|.
2708 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2710 * read.c (record_files): Instead of substituting % with
2711 actual stem value in dependency list replace it with $*.
2712 This fixes stem triple expansion bug.
2714 * implicit.c (pattern_search): Copy stem to a separate
2715 buffer and make it a properly terminated string. Assign
2716 this buffer instead of STEM (which is not terminated) to
2717 f->stem. Instead of substituting % with actual stem value
2718 in dependency list replace it with $*. This fixes stem
2719 triple expansion bug.
2721 2005-03-01 Paul D. Smith <psmith@gnu.org>
2723 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2724 on Windows, as it takes a handle not a pid. Just exit.
2725 Fix from patch #3679, provided by Alessandro Vesely.
2727 * configure.in: Update check for sys_siglist[] from autoconf manual.
2728 * signame.c (strsignal): Update to use the new autoconf macro.
2730 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2732 * read.c (record_files): Add a check for the list of prerequisites
2733 of a static pattern rule being empty. Fixes Savannah bug #12180.
2735 2005-02-28 Paul D. Smith <psmith@gnu.org>
2737 * doc/make.texi (Text Functions): Update docs to allow the end
2738 ordinal for $(wordlist ...) to be 0.
2739 * function.c (func_wordlist): Fail if the start ordinal for
2740 $(wordlist ...) is <1. Matches documentation.
2741 Resolves Savannah support request #103195.
2743 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2744 previously we were stopping when !-q, exactly the opposite. This
2745 has been wrong since version 1.34, in 1994!
2746 (update_file): If we got an error don't break out to run more
2747 double-colon rules: just return immediately.
2748 Fixes Savannah bug #7144.
2750 2005-02-27 Paul D. Smith <psmith@gnu.org>
2752 * misc.c (end_of_token): Make argument const.
2753 * make.h: Update prototype.
2755 * function.c (abspath, func_realpath, func_abspath): Use
2756 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2757 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2758 * read.c (record_files): Ditto.
2759 * variable.c (do_variable_definition): Ditto.
2761 * function.c (func_error): Create a new function $(info ...) that
2762 simply prints the message to stdout with no extras.
2763 (function_table_init): Add new function to the table.
2764 * NEWS: Add $(info ...) reference.
2765 * doc/make.texi (Make Control Functions): Document it.
2767 New feature: if the system supports symbolic links, and the user
2768 provides the -L/--check-symlink-time flag, then use the latest
2769 mtime between the symlink(s) and the target file.
2771 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2772 readlink(). If both are available, define MAKE_SYMLINKS.
2773 * main.c: New variable: check_symlink_flag.
2774 (usage): Add a line for -L/--check-symlink-times to the help string.
2775 (switches): Add -L/--check-symlink-times command line argument.
2776 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2777 print a warning and disable it again.
2778 * make.h: Declare check_symlink_flag.
2779 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2780 if the file is a symlink then check each link in the chain and
2781 choose the NEWEST mtime we find as the mtime for the file. The
2782 newest mtime might be the file itself!
2783 * NEWS: Add information about this new feature.
2784 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2786 Avoid core dumps described in Savannah bug # 12124:
2788 * file.c: New variable snapped_deps remember whether we've run
2790 (snap_deps): Set it.
2791 * filedef.h: Extern it.
2792 * read.c (record_files): Check snapped_deps; if it's set then
2793 we're trying to eval a new target/prerequisite relationship from
2794 within a command script, which we don't support. Fatal.
2796 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2798 Implementation of the .DEFAULT_TARGET special variable.
2800 * read.c (eval): If necessary, update default_target_name when
2802 * read.c (record_files): Update default_target_file if
2803 default_target_name has changed.
2804 * main.c (default_target_name): Define.
2805 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2806 default_target_name is set use default_target_file as a root
2808 * filedef.h (default_target_name): Declare.
2809 * dep.h (free_dep_chain):
2810 * misc.c (free_dep_chain): Change to operate on struct nameseq
2811 and change name to free_ns_chain.
2812 * file.c (snap_deps): Update to use free_ns_chain.
2814 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2816 Implementation of the second expansion in explicit rules,
2817 static pattern rules and implicit rules.
2819 * read.c (eval): Refrain from chopping up rule's dependencies.
2820 Store them in a struct dep as a single dependency line. Remove
2821 the code that implements SySV-style automatic variables.
2823 * read.c (record_files): Adjust the code that handles static
2824 pattern rules to expand all percents instead of only the first
2825 one. Reverse the order in which dependencies are stored so that
2826 when the second expansion reverses them again they appear in
2827 the makefile order (with some exceptions, see comments in
2828 the code). Remove the code that implements SySV-style automatic
2831 * file.c (snap_deps): Implement the second expansion and chopping
2832 of dependency lines for explicit rules.
2834 * implicit.c (struct idep): Define an auxiliary data type to hold
2835 implicit rule's dependencies after stem substitution and
2838 * implicit.c (free_idep_chain): Implement.
2840 * implicit.c (get_next_word): Implement helper function for
2841 parsing implicit rule's dependency lines into words taking
2842 into account variable expansion requests. Used in the stem
2845 * implicit.c (pattern_search): Implement the second expansion
2846 for implicit rules. Also fixes bug #12091.
2848 * commands.h (set_file_variables): Declare.
2849 * commands.c (set_file_variables): Remove static specifier.
2851 * dep.h (free_dep_chain): Declare.
2852 * misc.c (free_dep_chain): Implement.
2854 * variable.h (variable_expand_for_file): Declare.
2855 * expand.c (variable_expand_for_file): Remove static specifier.
2857 * make.h (strip_whitespace): Declare.
2858 * function.c (strip_whitespace): Remove static specifier.
2860 2005-02-26 Paul D. Smith <psmith@gnu.org>
2862 * main.c (main): Check for ferror() when reading makefiles from stdin.
2863 Apparently some shells in Windows don't close pipes properly and
2866 2005-02-24 Jonathan Grant <jg@jguk.org>
2868 * configure.in: Add MinGW configuration options, and extra w32 code
2870 * Makefile.am: Add MinGW configuration options, and extra w32 code
2872 * main.c: Determine correct program string (after last \ without .exe).
2873 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2875 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2876 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2877 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2878 environment support.
2880 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2882 * function.c (func_shell): When initializing error_prefix, check
2883 that reading file name is not null. This fixes long-standing
2884 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2886 2005-02-09 Paul D. Smith <psmith@gnu.org>
2888 * maintMakefile: Update the CVS download URL to simplify them.
2889 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2890 downloading the .texi files from Savannah now.
2892 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2894 * main.c (handle_non_switch_argument): Only add variables to
2895 command_variables if they're not already there: duplicate settings
2896 waste space and can be confusing to read.
2898 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2899 this header is never included by non-WINDOWS32 code, and it
2900 requires <config.h> to define which isn't always included first.
2902 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2903 testing MINGW32 versions.
2905 * main.c (log_working_directory): flush stdout to be sure the WD
2906 change is printed before any stderr messages show up.
2908 2005-02-01 Paul D. Smith <psmith@gnu.org>
2910 * maintMakefile (po_repo): Update the GNU translation site URL.
2912 2004-12-01 Paul D. Smith <psmith@gnu.org>
2914 * main.c (main): Change char* env_shell to struct variable shell_var.
2915 * variable.c (target_environment): Use new shell_var.
2917 2004-11-30 Paul D. Smith <psmith@gnu.org>
2919 * configure.in: The old way we avoided creating build.sh from
2920 build.sh.in before build.sh.in exists doesn't work anymore; we
2921 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2922 the help!). This also keeps automake from complaining.
2923 * Makefile.am (README): Add a dummy target so automake won't
2924 complain that this file doesn't exist when we checkout from CVS.
2925 * maintMakefile (.dep_segment): Rewrite this rule since newer
2926 versions of automake don't provide DEP_FILES.
2928 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2930 Implementation of `realpath' and `abspath' built-in functions.
2932 * configure.in: Check for realpath.
2933 * function.c (abspath): Return an absolute file name that does
2934 not contain any `.' or `..' components, nor repeated `/'.
2935 * function.c (func_abspath): For each name call abspath.
2936 * function.c (func_realpath): For each name call realpath
2937 from libc or delegate to abspath if realpath is not available.
2938 * doc/make.texi (Functions for File Names): Document new functions.
2939 * doc/make.texi (Quick Reference): Ditto.
2941 2004-11-28 Paul D. Smith <psmith@gnu.org>
2943 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2944 arguments. Fixes bug #10252.
2946 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2948 * main.c (main): Set SHELL to v_noexport by default. Remember the
2949 original environment setting of SHELL in the env_shell variable.
2950 * main.h: Export new env_shell variable.
2951 * variable.c (target_environment): If we find a v_noexport
2952 variable for SHELL, add a SHELL variable with the env_shell value.
2953 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2954 * doc/make.texi (Variables/Recursion): Ditto.
2956 2004-11-28 Paul D. Smith <psmith@gnu.org>
2958 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2959 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2960 Patch by Alessandro Vesely.
2962 2004-11-12 Paul D. Smith <psmith@gnu.org>
2964 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2965 the command line if it's inside a string.
2966 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2968 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2970 * function.c (func_lastword): New function: return last word
2971 from the list of words.
2972 * doc/make.texi: Document $(lastword ). Fix broken links in
2973 Quick Reference section.
2975 2004-10-06 Paul D. Smith <psmith@gnu.org>
2977 Apply patch from Alessandro Vesely, provided with bug # 9748.
2978 Fix use of tmpnam() to work with Borland C.
2980 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2981 construction of a temporary filename, and call new function
2982 create_batch_filename().
2983 (create_batch_filename) [WINDOWS32]: New function to create a
2986 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2988 * read.c (record_target_var): Expand simple pattern-specific
2990 * variable.c (initialize_file_variables): Do not expand simple
2991 pattern-specific variable.
2993 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2995 * remake.c (update_file_1): When rebuilding makefiles inherit
2996 dontcare flag from a target that triggered update.
2998 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
3000 * variable.c (initialize_file_variables): Mark pattern-specific
3001 variable as a per-target and copy export status.
3003 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
3005 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
3007 * implicit.c (pattern_search): When considering an implicit rule's
3008 prerequisite check that it is actually a target rather then
3009 just an entry in the file hashtable.
3011 2004-09-21 Paul D. Smith <psmith@gnu.org>
3013 * read.c (readstring): Fix some logic errors in backslash handling.
3014 (eval): Remove some unnecessary processing in buffer handling.
3015 (record_target_var): Assert that parse_variable_definition() succeeded.
3016 Reported by: Markus Mauhart <qwe123@chello.at>.
3018 * misc.c: Removed the sindex() function. All instances of this
3019 function were trivially replaceable by the standard strstr()
3020 function, and that function will always have better (or certainly
3021 no worse) performance than the very simple-minded algorithm
3022 sindex() used. This can matter with complex makefiles.
3023 * make.h: Remove the prototype for sindex().
3024 * function.c (subst_expand): Convert sindex() call to strstr().
3025 This means we no longer need to track the TLEN value so remove that.
3026 (func_findstring): Convert sindex() to strstr().
3027 * commands.c (chop_commands): Convert sindex() calls to strstr().
3028 Suggested by: Markus Mauhart <qwe123@chello.at>.
3030 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
3031 idea behind Savannah Patch #3144 from david.baird@homemail.com.
3032 If SHELL is set to CMD.EXE then assume it's batch-mode and
3033 non-unixy. I wrote the code differently from the patch, though,
3034 to make it safer. This also resolves bug #9174.
3036 2004-09-20 Paul D. Smith <psmith@gnu.org>
3038 * expand.c (variable_expand_string): Modify to invoke
3039 patsubst_expand() instead of subst_expand(); the latter didn't
3040 handle suffix patterns correctly.
3041 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
3042 was used only from variable_expand_string() and is no longer used
3044 (func_subst): Ditto, on call to subst_expand().
3045 (patsubst_expand): Require the percent pointers to point to the
3046 character after the %, not to the % itself.
3047 * read.c (record_files): New call criteria for patsubst_expand().
3048 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
3049 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
3051 2004-09-19 Paul D. Smith <psmith@gnu.org>
3053 * function.c (subst_expand): Fix a check in by_word: look for a
3054 previous blank if we're beyond the beginning of the string, not
3055 the beginning of the word.
3056 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3058 2004-05-16 Paul D. Smith <psmith@gnu.org>
3060 * remake.c (update_goal_chain): Change the argument specifying
3061 whether we're rebuilding makefiles to be a global variable,
3062 REBUILDING_MAKEFILES.
3063 (complain): Extract the code that complains about no rules to make
3064 a target into a separate function.
3065 (update_file_1): If we tried to rebuild a file during the makefile
3066 rebuild phase and it was dontcare, then no message was printed.
3067 If we then try to build the same file during the normal build,
3068 print a message this time.
3069 (remake_file): Don't complain about un-remake-able files when
3070 we're rebuilding makefiles.
3072 2004-05-11 Paul D. Smith <psmith@gnu.org>
3074 * job.c (construct_command_argv_internal): OS/2 patches from
3075 Andreas Buening <andreas.buening@nexgo.de>.
3077 2004-05-10 Paul D. Smith <psmith@gnu.org>
3079 * remake.c (update_file): Don't walk the double-colon chain unless
3080 this is a double-colon rule. Fix suggested by Boris Kolpackov
3081 <boris@kolpackov.net>.
3083 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3084 * readme.vms: New section describing OpenVMS support and issues.
3085 * default.c (default_variables): Add support for IA64.
3086 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3087 without some privilege aborts make with the error
3088 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3089 pressing Ctrl+Y and the input device is no terminal. The change
3090 catches this error and just continues.
3092 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3094 2004-04-25 Paul D. Smith <psmith@gnu.org>
3096 * commands.c (set_file_variables): Set $< properly in the face of
3097 order-only prerequisites.
3098 Patch from Boris Kolpackov <boris@kolpackov.net>
3100 2004-04-21 Bob Byrnes <byrnes@curl.com>
3102 * main.c (main): Notice failures to remake makefiles.

3106 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3108 * job.c: No default shell for RISC OS.
3109 (load_too_high): Hard-code the return to 1.
3110 (construct_command_argv_internal): No sh_chars or sh_cmds.
3111 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3113 2004-03-20 Paul D. Smith <psmith@gnu.org>
3115 * variable.c (do_variable_definition): Don't append from the
3116 global set if a previous non-appending target-specific variable
3117 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3120 * expand.c (reference_variable): Don't give up on variables with
3121 no value that have the target-specific append flag set: they might
3122 have a value after all. Reported by Oliver Schmidt
3123 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3124 <nikulin@dx1cmd.inp.nsk.su>.
3126 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3127 refer to absolute pathnames in directories that don't exist: some
3128 portion of the makefile could create those directories before we
3129 match the pattern. Fixes bugs #775 and #108.
3131 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3133 * main.c (main): Free makefile_mtimes if we have any.
3134 * README.W32.template: Update documentation for the current status
3135 of the MS-Windows port.
3136 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3137 environment variable is sometimes already defined which causes the
3139 * main.c (debug_signal_handler): Only define this function if
3140 SIGUSR1 is available.
3142 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3144 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3145 * README.OS2.template: Documentation updates.
3146 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3147 link line for safety.
3148 * maintMakefile (build.sh.in): Remove an extraneous ")".
3149 * job.c (child_execute_job): Close saved FDs.
3150 * job.c (exec_command) [OS/2]: exec_command(): If the command
3151 can't be exec'ed and if the shell is not Unix-sh, then try again
3152 with argv = { "cmd", "/c", ... }. Normally, this code is never
3153 reached for the cmd shell unless the command really doesn't exist.
3154 (construct_command_argv_internal) [OS/2]: The code for cmd
3155 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3156 The CMD builtin commands are case insensitive so use strcasecmp().
3158 2004-03-19 Paul D. Smith <psmith@gnu.org>
3160 * read.c (do_define): Re-order line counter increment so the count
3161 is accurate (we were losing one line per define). Reported by
3162 Dave Yost <Dave@Yost.com>.
3164 2004-03-06 Paul D. Smith <psmith@gnu.org>
3166 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3168 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3169 * misc.c (message,error,fatal): Ditto.
3170 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3171 * config.h.W32.template: Ditto.
3172 * config.h-vms.template: Ditto.
3173 * config.ami.template: Ditto.
3175 2004-03-04 Paul D. Smith <psmith@gnu.org>
3177 * README.template: Add a note about broken /bin/sh on SunOS
3178 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3180 * misc.c (message, error, fatal): Don't use "..." if we're using
3181 varargs. ansi2knr should handle this but it doesn't work: it
3182 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3183 done. On many systems (SunOS for example) va_dcl is a #define.
3184 So, force the use of the non-"..." version on pre-ANSI compilers.
3186 * maintMakefile (sign-dist): Create some rules to help automate
3187 the new GNU ftp upload method.
3189 2004-02-24 Paul D. Smith <psmith@gnu.org>
3191 * config.h.W32.template: Add HAVE_STDARG_H
3192 * config.h-vms.template: Ditto.
3193 * config.ami.template: Ditto.
3195 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3197 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3198 * build_w32.bat: Remove extra "+".
3200 2004-02-23 Paul D. Smith <psmith@gnu.org>
3202 * make.h: Create an UNUSED macro to mark unused parameters.
3203 * (many): Clean up warnings by applying UNUSED, fixing
3204 signed/unsigned incompatibilities, etc.
3206 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3208 * filedef.h: Name the command_state enumeration.
3209 * file.c (set_command_state): Use the enumeration in the function
3212 * configure.in: Explicitly set SET_MAKE to empty, to disable
3213 MAKE=make even when no make already exists. Fix bug #3823.
3215 2004-02-22 Paul D. Smith <psmith@gnu.org>
3217 * maintMakefile: Perl script to clean up all non-CVS files. Use
3218 it on all the subdirectories for the cvs-clean target.
3220 * main.c (decode_switches): Require non-empty strings for all our
3221 string command-line options. Fixes Debian bug # 164165.
3223 * configure.in: Check for stdarg.h and varargs.h.
3224 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3225 for printing messages.
3226 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3231 A number of patches for OS/2 support from Andreas Buening
3232 <andreas.buening@nexgo.de>:
3234 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3235 disable the SIGCHLD handler.
3236 (reap_children) [OS/2]: Remove special handling of job_rfd.
3237 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3238 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3239 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3240 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3241 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3244 2004-02-21 Paul D. Smith <psmith@gnu.org>
3246 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3247 <mail@kristov.de> reports that if process_begin() fails we don't
3248 handle the error condition correctly in all cases.
3249 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3250 to have a newline on the message.
3252 * job.c (construct_command_argv_internal): Add "test" to UNIX
3253 sh_cmds[]. Fixes Savannah bug # 7606.
3255 2004-02-04 Paul D. Smith <psmith@gnu.org>
3257 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3258 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3259 Hartmut Becker <Hartmut.Becker@hp.com>.
3261 2004-01-21 Paul D. Smith <psmith@gnu.org>
3263 * job.c (load_too_high): Implement an algorithm to control the
3264 "thundering herd" problem when using -l to control job creation
3265 via the load average. The system only recomputes the load once a
3266 second but we can start many jobs in a second. To solve this we
3267 keep track of the number of jobs started in the last second and
3268 apply a weight to try to guess what a correct load would be.
3269 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3270 Also fixes bug #4693.
3271 (reap_children): Decrease the job count for this second.
3272 (start_job_command): Increase the job count for this second.
3274 * read.c (conditional_line): Expand the text after ifn?def before
3275 checking to see if it's a single word. Fixes bug #7257.
3277 2004-01-09 Paul D. Smith <psmith@gnu.org>
3279 * file.c (print_file): Recurse to print all targets in
3280 double-colon rules. Fixes bug #4518, reported (with patch) by
3281 Andrew Chatham <chatham@google.com>.
3283 2004-01-07 Paul D. Smith <psmith@gnu.org>
3285 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3286 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3287 AC_FUNC_SETVBUF_REVERSED.
3289 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3290 (MAKE Variable): Fix Savannah bug #4898.
3292 * job.c (construct_command_argv_internal): Add "!" to the list of
3293 shell escape chars. POSIX sh allows it to appear before a
3294 command, to negate the exit code. Fixes bug #6404.
3296 * implicit.c (pattern_search): When matching an implicit rule,
3297 remember which dependencies have the ignore_mtime flag set.
3298 Original fix provided in Savannah patch #2349, by Benoit
3299 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3301 2003-11-22 Paul D. Smith <psmith@gnu.org>
3303 * README.W32.template (Outputs): Clarification on -j with
3304 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3307 2003-11-02 Paul D. Smith <psmith@gnu.org>
3309 * function.c (func_if): Strip all the trailing whitespace from the
3310 condition, then don't expand it. Fixed bug # 5798.
3312 * expand.c (recursively_expand_for_file): If we're expanding a
3313 variable with no file context, then use the variable's context.
3316 2003-10-21 Paul D. Smith <psmith@gnu.org>
3318 * main.c (log_working_directory): Add newlines to printf()s.
3320 * README.cvs: Add a note to ignore warnings during autoreconf.
3322 * maintMakefile (po_repo): Set a new URL for PO file updates.
3323 (get-config/config.guess get-config/config.sub): Get these files
3324 from the Savannah config project instead of ftp.gnu.org.
3326 2003-10-05 Paul Eggert <eggert@twinsun.com>
3328 * main.c (main): Avoid potential subscript error if environ has
3331 2003-08-22 Paul D. Smith <psmith@gnu.org>
3333 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3334 systems which don't yet implement the C89 standard :-/.
3336 2003-07-18 Paul D. Smith <psmith@gnu.org>
3338 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3339 [WINDOWS32]: Initialize hash.
3341 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3343 * dir.c (read_dirstream): Provide a workaround for broken versions of
3344 the MinGW dirent structure.
3346 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3348 * w32/include/dirent.h: Add __MINGW32__ filter.
3350 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3352 * make.h: Add global declaration of *make_host.
3353 * main.c (print_usage): Remove local declaration of *make_host.
3354 (print_version): Display "This program built for ..." after Copyright
3357 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3359 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3360 execution of "makeinfo --html make.texi".
3362 2003-04-30 Paul D. Smith <psmith@gnu.org>
3364 * build.template: Make some changes to maybe allow this script to
3365 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3367 * README.OS2.template: New file for OS/2 support. Original
3368 contributed by Andreas Buening.
3369 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3372 2003-04-19 Paul D. Smith <psmith@gnu.org>
3374 Fix bug #1405: allow a target to match multiple pattern-specific
3377 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3378 variable.c, where they've always belonged.
3379 * rule.h: Move the prototypes and struct pattern_var as well.
3380 * variable.c (initialize_file_variables): Invoke
3381 lookup_pattern_var() in a loop, until no more matches are found.
3382 If a match is found, create a new variable set for the target's
3383 pattern variables. Then merge the contents of each matching
3384 pattern variable set into the target's pattern variable set.
3385 (lookup_pattern_var): Change this function to be usable
3386 in a loop. It takes a starting position: if NULL, start at the
3387 beginning; if non-NULL, start with the pattern variable after that
3388 position, and return the next matching pattern.
3389 (create_pattern_var): Create a unique instance of
3390 pattern-specific variables for every definition in the makefile.
3391 Don't combine the same pattern together. This allows us to
3392 process the variable handling properly even when the same pattern
3393 is used multiple times.
3394 (parse_variable_definition): New function: break out the parsing
3395 of a variable definition line from try_variable_definition.
3396 (try_variable_definition): Call parse_variable_definition to
3398 (print_variable_data_base): Print out pattern-specific variables.
3399 * variable.h (struct variable): Remember when a variable is
3400 conditional. Also remember its flavor.
3401 (struct pattern_var): Instead of keeping a variable set, we just
3402 keep a single variable for each pattern.
3403 * read.c (record_target_var): Each pattern variable contains only a
3404 single variable, not a set, so create it properly.
3405 * doc/make.texi (Pattern-specific): Document the new behavior.
3407 2003-04-17 Paul D. Smith <psmith@gnu.org>
3409 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3410 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3411 file/directory naming rules for VMS so I can't tell whether this
3414 2003-04-09 Paul D. Smith <psmith@gnu.org>
3416 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3417 DOS-style pathnames: backslash separators and drive specifiers.
3419 2003-03-28 Paul D. Smith <psmith@gnu.org>
3421 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3422 the intermediate flag on all targets. Fixes bug #2515.
3424 2003-03-24 Paul D. Smith <psmith@gnu.org>
3426 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3427 Upgrade to autoconf 2.57 and automake 1.7.3.
3429 * job.c: More OS/2 changes from Andreas Buening.
3431 * file.c (print_file): Fix variable initialization.
3434 * remake.c (notice_finished_file):
3436 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3437 some calls (like readdir()) return NULL in valid situations
3438 without resetting errno. Fixes bug #2846.
3440 2003-02-25 Paul D. Smith <psmith@gnu.org>
3442 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3444 * job.c (_is_unixy_shell) [OS/2]: New function.
3445 Set default shell to /bin/sh.
3446 (reap_children): Close the job_rfd pipe here since we don't use a
3448 (set_child_handler_action_flags): define this to empty on OS/2.
3449 (start_job_command): Close the jobserver pipe and use
3450 child_execute_job() instead of fork/exec.
3451 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3452 rather than exec'ing, then reconfigure stdin/stdout.
3453 (exec_command): Rewrite to use spawn instead of exec. Return the
3456 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3457 in DOS. Handle the TEMP environment variable as in DOS. Don't
3458 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3459 use -j in DOS mode. Use child_execute_job() instead of
3462 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3465 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3466 prototypes that return values.
3468 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3470 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3471 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3473 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3476 2003-02-24 Paul D. Smith <psmith@gnu.org>
3478 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3479 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3480 (child_execute_job) [VMS]: Handle error status properly.
3481 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3483 * function.c (func_shell): Use EINTRLOOP() while reading from the
3484 subshell pipe (Fixes bug #2502).
3485 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3487 * main.c (main): Ditto.
3489 2003-01-30 Paul D. Smith <psmith@gnu.org>
3491 * read.c (eval): eval() was not fully reentrant, because the
3492 collapsed buffer was static. Change it to be an automatic
3493 variable so that eval() can be invoked recursively.
3495 (eval): Apply patch # 1022: fix memory reference error on long
3496 target-specific variable lines.
3497 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3499 * function.c (check_numeric): Combine the is_numeric() function
3500 into this function, since it's only called from one place.
3501 Constify this function. Have it print the incorrect string in the
3502 error message. Fixes bug #2407.
3503 (strip_whitespace): Constify.
3504 (func_if): Constify.
3505 * expand.c (expand_argument): Constify.
3507 2003-01-29 Paul D. Smith <psmith@gnu.org>
3509 Fix bug # 2169, also reported by other people on various systems.
3511 * make.h: Some systems, such as Solaris and PTX, do not fully
3512 implement POSIX-compliant SA_RESTART functionality; important
3513 system calls like stat() and readdir() can still fail with EINTR
3514 even if SA_RESTART has been set on the signal handler. So,
3515 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3516 EINTR for system calls which return -1 or 0 (NULL), respectively,
3518 Also, remove the old atomic_stat()/atomic_readdir() and
3519 HAVE_BROKEN_RESTART handling.
3521 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3523 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3524 * remake.c (touch_file): Ditto.
3526 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3527 * read.c (construct_include_path): Ditto.
3528 * remake.c (name_mtime): Ditto.
3529 * vpath.c (selective_vpath_search): Ditto.
3530 * dir.c (find_directory): Ditto.
3531 (local_stat): Ditto.
3532 (find_directory): Use ENULLLOOP() to wrap opendir().
3533 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3535 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3536 atomic_readdir() handling.
3538 2003-01-22 Paul D. Smith <psmith@gnu.org>
3540 * function.c (func_call): Fix Bug #1744. If we're inside a
3541 recursive invocation of $(call ...), mask any of the outer
3542 invocation's arguments that aren't used by this one, so that this
3543 invocation doesn't "inherit" them accidentally.
3545 2002-12-05 Paul D. Smith <psmith@gnu.org>
3547 * function.c (subst_expand): Valery Khamenia reported a
3548 pathological performance hit when doing substitutions on very
3549 large values with lots of words: turns out we were invoking
3550 strlen() a ridiculous number of times. Instead of having each
3551 call to sindex() call strlen() again, keep track of how much of
3552 the text we've seen and pass the length to sindex().
3554 2002-11-19 Paul D. Smith <psmith@gnu.org>
3556 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3559 2002-11-16 Paul D. Smith <psmith@gnu.org>
3561 * NMakefile.template (OBJS): Add hash.c object file.
3562 * SMakefile.template (srcs): Ditto.
3563 * Makefile.ami (objs): Ditto.
3564 * build_w32.bat: Ditto.
3566 * Makefile.DOS.template: Remove extra dependencies.
3568 2002-10-25 Paul D. Smith <psmith@gnu.org>
3570 * expand.c (install_variable_buffer): New function. Install a new
3571 variable_buffer context and return the previous one.
3572 (restore_variable_buffer): New function. Free the current
3573 variable_buffer context and put a previously saved one back.
3574 * variable.h: Prototypes for {install,restore}_variable_buffer.
3575 * function.c (func_eval): Push a new variable_buffer context
3576 before we eval, then restore the old one when we're done.
3579 * read.c (install_conditionals): New function. Install a new
3580 conditional context and return the previous one.
3581 (restore_conditionals): New function. Free the current
3582 conditional context and put a previously saved one back.
3583 (eval): Use the {install,restore}_conditionals for "include"
3585 (eval_buffer): Use {install,restore}_conditionals to preserve the
3586 present conditional state before we evaluate the buffer.
3589 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3591 (Recursion): Add a variable index entry for CURDIR.
3593 * README.cvs: Update to appropriate versions.
3594 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3595 don't need to copy loadavg.c: automake is smart enough to create
3596 it for me. Still have a bug in automake related to ansi2knr tho.
3598 2002-10-14 Paul D. Smith <psmith@gnu.org>
3600 * remake.c (notice_finished_file): Only touch targets if they have
3601 at least one command (as per POSIX). Resolve Bug #1418.
3603 * *.c: Convert to using ANSI C-style function definitions.
3604 * Makefile.am: Enable the ansi2knr feature of automake.
3605 * configure.in: ditto.
3607 2002-10-13 Paul D. Smith <psmith@gnu.org>
3609 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3610 for automatic variable values like $^, etc. In the case of very
3611 large lists of prerequisites this causes problems. Instead reuse
3612 a static buffer (resizeable) for each variable.
3614 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3615 target-specific variable definitions. Check for it and set an
3617 (record_target_var): Set the export field to v_export if the
3618 "exported" flag is set.
3619 * doc/make.texi (Target-specific): Document the ability to use
3622 * doc/make.texi: Change the name of the section on automatic
3623 variables from "Automatic" to "Automatic Variables". Added text
3624 clarifying the scope of automatic variables.
3626 2002-10-04 Paul D. Smith <psmith@gnu.org>
3628 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3630 (record_files): Ditto.
3632 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3633 the search for the '=' to only within the enclosing parens.
3635 2002-10-03 Paul D. Smith <psmith@gnu.org>
3637 Version 3.80 released.
3639 * dir.c: Change hash functions to use K&R function definition style.
3640 * function.c: Ditto.
3642 * variable.c: Ditto.
3644 Update to automake 1.7.
3646 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3647 (pdf): Remove this target as automake now provides one.
3649 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3651 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3653 * makefile.com: Updates for GNU make 3.80.
3654 * makefile.vms: Ditto.
3656 2002-09-23 Paul D. Smith <psmith@gnu.org>
3658 * read.c (enum make_word_type): Remove w_comment.
3659 (get_next_mword): Don't treat comment characters as special; where
3660 this function is used we will never see a comment (it's stripped
3661 before we get here) and treating comments specially means that
3662 targets like "foo\#bar" aren't handled properly.
3664 2002-09-18 Paul D. Smith <psmith@gnu.org>
3666 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3668 * read.c (eval): Expansion of arguments to export/unexport was
3669 ignoring all arguments after the first one. Change the algorithm
3670 to expand the whole line once, then parse the results.
3672 2002-09-17 Paul D. Smith <psmith@gnu.org>
3674 Fix Bug #940 (plus another bug I found while looking at this):
3676 * read.c (record_target_var): enter_file() will add a new entry if
3677 it's a double-colon target: we don't want to do that in this
3678 situation. Invoke lookup_file() and only enter_file() if it does
3679 not already exist. If the file we get back is a double-colon then
3680 add this variable to the "root" double-colon target.
3682 * variable.c (initialize_file_variables): If this file is a
3683 double-colon target but is not the "root" target, then initialize
3684 the root and make the root's variable list the parent of our
3687 2002-09-13 Paul D. Smith <psmith@gnu.org>
3689 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3691 * hash.c (round_up_2): Get rid of a warning.
3693 2002-09-12 Paul D. Smith <psmith@gnu.org>
3695 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3696 so it doesn't complain about getloadavg.c.
3698 * commands.c (set_file_variables): Make sure we always alloca() at
3699 least 1 character for the value of $? (for '\0').
3701 2002-09-11 Paul D. Smith <psmith@gnu.org>
3703 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3704 macro to use RESULT instead of the incorrect _RESULT_.
3706 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3707 and atomic_readdir(). We need to #include dirent.h to get this to
3709 * misc.c (atomic_readdir): Fix typos.
3711 2002-09-10 Paul D. Smith <psmith@gnu.org>
3713 * read.c (eval): Expand variable lists given to export and
3714 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3715 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3717 * doc/make.texi (Variables/Recursion): Document this.
3718 (Conditional Syntax): And here.
3720 2002-09-09 Paul D. Smith <psmith@gnu.org>
3722 * configure.in: Check for memmove().
3724 2002-09-07 Paul D. Smith <psmith@gnu.org>
3726 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3727 Michael Sterrett <msterret@coat.com> reports that while it has
3728 SA_RESTART, it does not work properly.
3730 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3731 that invokes stat() and loops to do it again if it returns EINTR.
3732 (atomic_readdir): Ditto, with readdir().
3734 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3735 and readdir() to atomic_stat() and atomic_readdir().
3737 2002-09-04 Paul D. Smith <psmith@gnu.org>
3739 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3740 reports that GNU make sometimes doesn't recognize that targets can
3741 be made, when directories can be created as prerequisites. He
3742 reports that changing the order of predicates in the DEP->changed
3743 flag test so that lookup_file() is always performed, solves this
3746 2002-08-08 Paul D. Smith <psmith@gnu.org>
3748 * configure.in: Require a newer version of gettext.
3750 * misc.c (perror_with_name): Translate the format string (for
3751 right-to-left language support).
3752 (pfatal_with_name): Ditto.
3754 * main.c: Create a static array of strings to store the usage
3755 text. This is done to facilitate translations.
3756 (struct command_switch): Remove argdesc and description fields.
3757 (switches): Remove values for obsolete fields.
3758 (print_usage): Print each element of the usage array.
3760 * hash.c: Change function definitions to be K&R style.
3762 2002-08-02 Paul D. Smith <psmith@gnu.org>
3764 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3765 this one because it's too hard to get right. We'll look at it for
3767 * main.c (main): Don't create the .TARGETS variable.
3768 * variable.c (handle_special_var): Don't handle .TARGETS.
3770 2002-08-01 Paul D. Smith <psmith@gnu.org>
3772 * main.c (switches): Add a new option, -B (--always-make). If
3773 specified, make will rebuild all targets that it encounters even
3774 if they don't appear to be out of date.
3775 (always_make_flag): New flag.
3776 * make.h: Extern always_make_flag.
3777 * remake.c (update_file_1): Check always_make_flag; if it's set we
3778 will always rebuild any target we can, even if none of its
3779 prerequisites are newer.
3782 * doc/make.texi (Shell Function): Make it clear that make
3783 variables marked as "export" are not passed to instances of the
3786 Add new introspection variable .VARIABLES and .TARGETS.
3788 * variable.c (handle_special_var): New function. If the variable
3789 reference passed in is "special" (.VARIABLES or .TARGETS),
3790 calculate the new value if necessary. .VARIABLES is handled here:
3791 walk through the hash of defined variables and construct a value
3792 which is a list of the names. .TARGETS is handled by
3793 build_target_list().
3794 (lookup_variable): Invoke handle_special_var().
3795 * file.c (build_target_list): Walk through the hask of known files
3796 and construct a list of the names of all the ones marked as
3798 * main.c (main): Initialize them to empty (and as simple variables).
3799 * doc/make.texi (Special Variables): Document them.
3800 * NEWS: Mention them.
3802 * variable.h (struct variable): Add a new flag "exportable" which
3803 is true if the variable name is valid for export.
3804 * variable.c (define_variable_in_set): Set "exportable" when a new
3805 variable is defined.
3806 (target_environment): Use the "exportable" flag instead of
3807 re-checking the name here... an efficiency improvement.
3809 2002-07-31 Paul D. Smith <psmith@gnu.org>
3811 * config.h-vms.template: Updates to build on VMS. Thanks to
3812 Brian_Benning@aksteel.com for helping verify the build.
3813 * makefile.com: Build the new hash.c file.
3814 * hash.h: Use strcpmi(), not stricmp(), in the
3815 HAVE_CASE_INSENSITIVE_FS case.
3817 2002-07-30 Paul D. Smith <psmith@gnu.org>
3819 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3820 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3821 Reported by <Brian_Benning@aksteel.com>.
3823 2002-07-10 Paul D. Smith <psmith@gnu.org>
3825 * variable.c (pop_variable_scope): Remove variable made unused by
3826 new hash infrastructure.
3827 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3828 comparisons as well as name comparisons.
3829 * variable.h: Add a prototype for new hash_init_function_table().
3830 * file.c (lookup_file): Remove variables made unused by new hash
3832 * dir.c (directory_contents_hash_2): Missing return of hash value.
3833 (dir_contents_file_exists_p): Remove variables made unused by new
3834 hash infrastructure.
3837 Installed Greg McGary's integration of the hash functions from the
3838 GNU id-utils package:
3840 2002-07-10 Greg McGary <greg@mcgary.org>
3842 * scripts/functions/filter-out: Add literals to to the
3843 pattern space in order to add complexity, and trigger
3844 use of an internal hash table. Fix documentation strings.
3845 * scripts/targets/INTERMEDIATE: Reverse order of files
3846 passed to expected `rm' command.
3848 2002-07-10 Greg McGary <greg@mcgary.org>

3940 2002-07-10 Paul D. Smith <psmith@gnu.org>
3942 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3943 prerequisite list. A real SysV make will expand the entire
3944 prerequisites list _twice_: we don't do that as it's a big
3945 backward-compatibility problem. We only replace those specific
3948 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3949 references left in the list of prerequisites. Check for .POSIX as
3950 we record targets, so we can disable non-POSIX behavior while
3951 reading makefiles as well as running them.
3952 (eval): Check the prerequisite list to see if we have anything
3953 that looks like a SysV prerequisite variable reference.
3955 2002-07-09 Paul D. Smith <psmith@gnu.org>
3957 * doc/make.texi (Prerequisite Types): Add a new section describing
3958 order-only prerequisites.
3960 * read.c (uniquize_deps): If we have the same file as both a
3961 normal and order-only prereq, get rid of the order-only prereq,
3962 since the normal one supersedes it.
3964 2002-07-08 Paul D. Smith <psmith@gnu.org>
3966 * AUTHORS: Added Greg McGary to the AUTHORS file.
3967 * NEWS: Blurbed order-only prerequisites.
3968 * file.c (print_file): Show order-only deps properly when printing
3971 * maintMakefile: Add "update" targets for wget'ing the latest
3972 versions of various external files. Taken from Makefile.maint in
3975 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3976 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3978 2002-07-07 Paul D. Smith <psmith@gnu.org>
3980 * po/*.po: Remove. We'll use wget to retrieve them at release
3983 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3984 rather than a shell you get an exception. Make sure we look up
3985 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3987 * remake.c (notice_finished_file): Fix handling of -t flag.
3988 Patch provided by Henning Makholm <henning@makholm.net>.
3990 * implicit.c (pattern_search): Some systems apparently run short
3991 of stack space, and using alloca() in this function caused an
3992 overrun. I modified it to use xmalloc() on the two variables
3993 which seemed like they might get large. Fixes Bug #476.
3995 * main.c (print_version): Update copyright notice to conform with
3997 (print_usage): Update help output.
3999 * function.c (func_eval): Create a new make function, $(eval
4000 ...). Expand the arguments, put them into a buffer, then invoke
4001 eval_buffer() on the resulting string.
4002 (func_quote): Create a new function, $(quote VARNAME). Inserts
4003 the value of the variable VARNAME without expanding it any
4006 * read.c (struct ebuffer): Change the linebuffer structure to an
4007 "eval buffer", which can be either a file or a buffer.
4008 (eval_makefile): Move the code in the old read_makefile() which
4009 located a makefile into here: create a struct ebuffer with that
4010 information. Have it invoke the new function eval() with that
4012 (eval_buffer): Create a new function that creates a struct ebuffer
4013 that holds a string buffer instead of a file. Have it invoke
4014 eval() with that ebuffer.
4015 (eval): New function that contains the guts of the old
4016 read_makefile() function: this function parses makefiles. Obtains
4017 data to parse from the provided ebuffer. Some modifications to
4018 make the flow of the function cleaner and clearer. Still could
4019 use some work here...
4020 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
4021 contents of the define/endef variable from the ebuffer.
4022 (readstring): Read the next line from a string-style ebuffer.
4023 (readline): Read the next line from an ebuffer. If it's a string
4024 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
4027 * dep.h (eval_buffer): Prototype eval_buffer();
4029 * variable.c (do_variable_definition): Make sure that all
4030 non-target-specific variables are registered in the global set.
4031 If we're invoked from an $(eval ...) we might be inside a $(call
4032 ...) or other function which has pushed a variable scope; we still
4033 want to define our variables from evaluated makefile code in the
4036 2002-07-03 Greg McGary <greg@mcgary.org>
4038 * dep.h (struct dep) [ignore_mtime]: New member.
4039 [changed]: convert to a bitfield.
4040 * implicit.c (pattern_search): Zero ignore_mtime.
4041 * main.c (main, handle_non_switch_argument): Likewise.
4042 * rule.c (convert_suffix_rule): Likewise.
4043 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
4044 (read_makefile): Parse '|' in prerequisite list.
4045 (uniquize_deps): Consider ignore_mtime when comparing deps.
4046 * remake.c (update_file_1, check_dep): Don't force remake for
4047 dependencies that have d->ignore_mtime.
4048 * commands.c (FILE_LIST_SEPARATOR): New constant.
4049 (set_file_variables): Don't include a
4050 prerequisite in $+, $^ or $? if d->ignore_mtime.
4053 2002-06-18 Paul D. Smith <psmith@gnu.org>
4055 * make.texinfo: Updates for next revision. New date/rev/etc.
4056 Recreate all Info menus. Change license on the manual to the GNU
4057 Free Documentation License. A number of typos.
4058 (Variables Simplify): Don't use "-" before it's defined.
4059 (Automatic Prerequisites): Rewrite the target example to work
4060 properly if the compile fails. Remove incorrect comments about
4061 how "set -e" behaves.
4062 (Text Functions): Move the "word", "wordlist", "words", and
4063 "firstword" functions here, from "File Name Functions".
4064 * make-stds.texi: Update from latest GNU version.
4065 * fdl.texi: (created) Import the latest GNU version.
4067 2002-06-06 Paul D. Smith <psmith@gnu.org>
4069 * variable.c (do_variable_definition): New function: extract the
4070 part of try_variable_definition() that actually sets the value
4071 into a separate function.
4072 (try_variable_definition): Call do_variable_definition() after
4073 parsing the variable definition string.
4074 (define_variable_in_set): Make the name argument const.
4076 * variable.h (enum variable_flavor): Make public.
4077 (do_variable_definition): Create prototype.
4079 * read.c (read_all_makefiles): Create a new built-in variable,
4081 (read_makefile): Add each makefile read in to this variable value.
4083 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4085 * Makefile.DOS.template: Tweak according to changes in the
4086 distribution. Add back the dependencies of *.o files.
4088 * configh.dos.template: Synchronize with config.h.in.
4090 2002-05-09 Paul D. Smith <psmith@gnu.org>
4092 * file.c (file_timestamp_now): Use K&R function declaration.
4094 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4095 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4096 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4097 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4098 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4099 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4100 nlist.n_name is a pointer rather than an array.
4102 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4103 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4104 * configure.in: Use it instead of the old version.
4106 * main.c (main): Prefer setvbuf() to setlinebuf().
4108 2002-05-08 Paul D. Smith <psmith@gnu.org>
4110 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4111 (loadavg_LDADD): Ditto.
4113 2002-04-29 Paul D. Smith <psmith@gnu.org>
4115 * expand.c (recursively_expand_for_file): Rename
4116 recursively_expand() to recursively_expand_for_file() and provide
4117 an extra argument, struct file. If the argument is provided, set
4118 the variable scope to that of the file before expanding.
4119 * variable.h (recursively_expand): Make this a macro that invokes
4120 recursively_expand_for_file() with a NULL file pointer.
4121 * variable.c (target_environment): Call the renamed function and
4122 provide the current file context.
4123 Fixes Debian bug #144306.
4125 2002-04-28 Paul D. Smith <psmith@gnu.org>
4127 Allow $(call ...) user-defined variables to be self-referencing
4128 without throwing an error. Allows implementation of transitive
4129 closures, among other possibly useful things.
4130 Requested by: Philip Guenther <guenther@sendmail.com>
4132 * variable.h (struct variable): Add a new field: exp_count, and
4133 new macros to hold its size and maximum value.
4134 (warn_undefined): Make this a macro.
4135 * variable.c (define_variable_in_set): Initialize it.
4136 * expand.c (recursively_expand): If we detect recursive expansion
4137 of a variable, check the exp_count field. If it's greater than 0
4138 allow the recursion and decrement the count.
4139 (warn_undefined): Remove this (now a macro in variable.h).
4140 * function.c (func_call): Before we expand the user-defined
4141 function, modify its exp_count field to contain the maximum
4142 number of recursive calls we'll allow. After the call, reset it
4145 2002-04-21 Paul D. Smith <psmith@gnu.org>
4147 Modified to use latest autoconf (2.53), automake (1.6.1), and
4148 gettext (0.11.1). We're using gettext's new "external" support,
4149 to avoid including libintl source with GNU make.
4151 * README.cvs: New file. Explain how to build GNU make from CVS.
4153 * configure.in: Modify checking for the system glob library.
4154 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4155 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4156 etc. will manage it correctly). Set an automake conditional
4157 USE_LOCAL_GLOB to decide whether to compile the glob library.
4159 * getloadavg.c (main): Include make.h in the "TEST" program to
4162 * Makefile.am: Remove special rules for loadavg. Replace them
4163 with Automake capabilities for building extra programs.
4165 * signame.c: This file does nothing if the system provide
4166 strsignal(). If not, it implements strsignal(). If the system
4167 doesn't define sys_siglist, then we make our own; otherwise we use
4169 * signame.h: Removed.
4171 * main.c (main): No need to invoke signame_init(). Update copyright.
4173 * ABOUT-NLS: Removed.
4174 * gettext.c: Removed.
4175 * gettext.h: Get a simplified copy from the gettext package.
4177 * i18n/*.po: Moved to po/.
4180 * config/*: Created. Contains package configuration helper files.
4181 * config.guess, config.sub: Moved to config directory.
4183 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4184 Rework to use new-style autoconf features. Use the "external"
4185 mode for gettext. Make the build.sh config file conditional on
4186 whether build.sh.in exists, to avoid autoconf errors.
4187 * acinclude.m4: Removed almost all macros as being obsolete.
4188 Rewrote remaining macros to use AC_DEFINE.
4189 * acconfig.h: Removed.
4191 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4192 conditional to handle customs support. Remove special handling
4195 2002-04-20 Paul D. Smith <psmith@gnu.org>
4197 * function.c (func_call): Don't mark the argument variables $1,
4198 etc. as recursive. They've already been fully expanded so
4199 there's no need to do it again, and doing so strips escaped $'s.
4200 Reported by Sebastian Glita <glseba@yahoo.com>.
4202 * remake.c (notice_finished_file): Walk through double-colon
4203 entries via the prev field, not the next field!
4204 Reported by Greg McGary <greg@mcgary.org>.
4206 * main.c (main): If the user specifies -q and asks for a specific
4207 target which is a makefile, we got an assert. In that case it
4208 turns out we should continue normally instead.
4210 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4212 * i18n/he.po: Installed a new translation.
4214 2002-01-07 Paul D. Smith <psmith@gnu.org>
4216 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4218 2001-12-04 Paul D. Smith <psmith@gnu.org>
4220 * i18n/ja.po: Installed an updated translation.
4222 2001-09-06 Paul Eggert <eggert@twinsun.com>
4224 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4225 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4227 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4229 (main): Get rid of any avoidable limit on stack size.
4231 2001-09-04 Paul D. Smith <psmith@gnu.org>
4233 * i18n/da.po: Installed an updated translation.
4235 2001-08-03 Paul D. Smith <psmith@gnu.org>
4237 * i18n/fr.po: Installed an updated translation.
4238 Resolves Debian bug #106720.
4240 2001-06-13 Paul D. Smith <psmith@gnu.org>
4242 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4245 2001-06-11 Paul D. Smith <psmith@gnu.org>
4247 * i18n/ko.po: Installed a new translation.
4249 2001-05-06 Paul D. Smith <psmith@gnu.org>
4251 Modify the EINTR handling.
4253 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4254 the way in which we manage the file descriptor/signal handler race
4255 trap to be more efficient.
4257 2001-05-06 Paul Eggert <eggert@twinsun.com>
4259 Restart almost all system calls that are interrupted, instead
4260 of worrying about EINTR. The lone exception is the read() for
4263 * configure.in (HAVE_SA_RESTART): New macro.
4264 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4265 * main.c (main): Use SA_RESTART instead of the old,
4266 nonstandard SA_INTERRUPT.
4268 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4269 * main.c (bsd_signal): New function or macro,
4270 if the implementation doesn't supply it.
4271 (The bsd_signal function will be in POSIX 1003.1-200x.)
4272 (HANDLESIG): Remove.
4273 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4275 * make.h (EINTR_SET): Remove.
4276 (SA_RESTART): New macro.
4278 * arscan.c (ar_member_touch): Don't worry about EINTR.
4279 * function.c (func_shell): Likewise.
4280 * job.c (reap_children, free_child, new_job): Likewise.
4281 * main.c (main): Likewise.
4282 * remake.c (touch_file, name_mtime): Likewise.
4284 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4285 if fstat failed with errno!=EINTR, the error was ignored.
4287 * job.c (set_child_handler_action_flags): New function.
4288 (new_job): Use it to temporarily clear the SIGCHLD action flags
4289 while reading the token.
4291 2001-05-02 Paul D. Smith <psmith@gnu.org>
4293 * job.c (start_job_command): Don't add define/endef per-line flags
4294 to the top-level flags setting.
4296 2001-04-03 Paul D. Smith <psmith@gnu.org>
4298 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4299 bit on error, so check for odd return values, not non-0 return
4301 (VMS_get_member_info): Calculate the timezone differences correctly.
4302 Reported by John Fowler <jfowler@nyx.net>.
4305 2001-03-14 Paul D. Smith <psmith@gnu.org>
4307 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4308 value before invoking define_variable().
4309 Reported by John Fowler <jfowler@nyx.net>.
4311 2001-02-07 Paul D. Smith <psmith@gnu.org>
4313 * read.c (record_target_var): If we reset the variable due to a
4314 command-line variable setting overriding it, turn off the "append"
4317 2001-01-17 Paul D. Smith <psmith@gnu.org>
4319 * variable.c (lookup_variable) [VMS]: When getting values from the
4320 environment, allocate enough space for the _value_ plus escapes,
4321 not enough space for the name plus escapes :-/.
4322 Reported by John Fowler <jfowler@nyx.net>.
4324 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4325 warnings that make generates, so it doesn't look like an error.
4326 Reported by Karl Berry <karl@gnu.org>.
4329 Fix for PR/2020: Rework appended target-specific variables. I'm
4330 fairly confident this algorithm is finally correct.
4332 * expand.c (allocated_variable_append): Rewrite. Instead of
4333 expanding each appended variable then adding all the expanded
4334 strings together, we append all the unexpanded values going up
4335 through the variable set contexts, then expand the final result.
4336 This behaves just like non-target-specific appended variable
4337 values, while the old way didn't in various corner cases.
4338 (variable_append): New function: recursively append the unexpanded
4339 value of a variable, walking from the outermost variable scope to
4341 * variable.c (lookup_variable): Remove the code that looked up the
4342 variable set list if the found variable was "append". We don't
4344 (lookup_variable_in_set): Make this non-static so we can use it
4346 (try_variable_definition): Use lookup_variable_in_set() rather
4347 than faking out current_variable_set_list by hand (cleanup).
4348 * variable.h: Add a prototype for the now non-static
4349 lookup_variable_in_set().
4351 2000-11-17 Paul D. Smith <psmith@gnu.org>
4353 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4354 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4355 before throwing a fit.
4357 2000-11-17 Paul D. Smith <psmith@gnu.org>
4359 * read.c (readline): CRLF calculations had a hole, if you hit the
4360 buffer grow scenario just right. Reworked the algorithm to avoid
4361 the need for len or lastlen at all. Problem description with
4362 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4364 2000-10-24 Paul D. Smith <psmith@gnu.org>
4366 * gettext.c (SWAP): Declare this with the prototype, otherwise
4367 some systems don't work (non-32-bit? Reported for Cray T3E).
4368 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4370 2000-10-05 Paul D. Smith <psmith@gnu.org>
4372 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4373 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4375 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4377 2000-09-22 Paul D. Smith <psmith@gnu.org>
4379 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4380 parts of the real gettext.h here, and we expect to really include
4381 the real gettext.h later. If we keep this #define, it's ignored.
4383 2000-09-21 Paul D. Smith <psmith@gnu.org>
4385 * main.c (log_working_directory): Rework the text to use complete
4386 sentences, to make life simpler for the translators.
4388 2000-08-29 Paul D. Smith <psmith@gnu.org>
4390 * file.c (remove_intermediates): Print a debug message before we
4391 remove intermediate files, so the user (if she uses -d) knows
4394 2000-08-21 Paul D. Smith <psmith@gnu.org>
4396 * variable.c (try_variable_definition): Change how we handle
4397 target-specific append variable defns: instead of just setting the
4398 value, expand it as an append _but_ only within the current
4399 target's context. Otherwise we lose all but the last value if the
4400 variable is appended more than once within the current target
4401 context. Fixes PR/1831.
4403 2000-08-16 Paul D. Smith <psmith@gnu.org>
4405 * function.c (func_shell): Nul-terminate the buffer before
4406 printing an exec error message (just in case it's not!).
4407 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4409 2000-07-25 Paul D. Smith <psmith@gnu.org>
4411 * job.c (construct_command_argv_internal): Add "~" to the list of
4412 sh_chars[] which disallow optimizing out the shell call.
4414 2000-07-23 Paul Eggert <eggert@twinsun.com>
4416 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4417 supersedes --disable-nsec-timestamps.
4418 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4419 * README: Remove --disable-nsec-timestamps.
4421 * filedef.h (struct file.low_resolution_time): New member.
4422 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4423 * remake.c (update_file_1):
4424 Avoid spurious rebuilds due to low resolution time stamps,
4425 generalizing the earlier code that applied only to archive members.
4426 (f_mtime): Archive members always have low resolution time stamps.
4428 * configure.in: Remove --disable-nsec-timestamps, as this has
4429 been superseded by .LOW_RESOLUTION_TIME.
4431 2000-07-23 Paul Eggert <eggert@twinsun.com>
4433 * configure.in (enable_nsec_timestamps): Renamed from
4434 make_cv_nsec_timestamps, since enable/disable options
4435 shouldn't be cached.
4437 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4438 and Paul Eggert <eggert@twinsun.com>
4440 * file.c (file_timestamp_now):
4441 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4442 so that clock_gettime is not linked unless needed.
4444 * filedef.h (FILE_TIMESTAMP_HI_RES):
4445 Remove definition; "configure" now does this.
4447 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4448 to before high resolution file timestamp check,
4449 since that check now uses uintmax_t.
4450 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4451 high resolution file timestamps.
4452 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4453 so that we don't link in clock_gettime unnecessarily.
4455 2000-07-17 Paul D. Smith <psmith@gnu.org>
4457 * i18n/ja.po: New version of the translation file.
4459 2000-07-07 Paul D. Smith <psmith@gnu.org>
4461 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4462 the offset calculation.
4463 (name_mtime): Replace EINTR test with EINTR_SET macro.
4465 2000-07-07 Paul Eggert <eggert@twinsun.com>
4469 * remake.c (update_file_1):
4470 Avoid spurious rebuilds of archive members due to their
4471 timestamp resolution being only one second.
4472 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4473 the clock's resolution being lower than file timestamps'.
4474 When warning about future timestamps, report only the discrepancy,
4475 not the absolute value of the timestamp and the current time.
4477 * file.c (file_timestamp_now): New arg RESOLUTION.
4478 * filedef.h (file_timestamp_now): Likewise.
4479 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4481 2000-07-05 Paul D. Smith <psmith@gnu.org>
4483 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4484 to listp. Fixes PR/1793.
4486 2000-06-26 Paul Eggert <eggert@twinsun.com>
4488 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4490 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4492 * remake.c (f_mtime): Remove unused var memtime.
4494 2000-06-25 Martin Buchholz <martin@xemacs.org>
4496 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4497 Ran spell-check on make.texinfo.
4499 2000-06-23 Paul D. Smith <psmith@gnu.org>
4501 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4502 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4503 * make.h: Define these macros.
4505 * Version 3.79.1 released.
4507 * configure.in: Add a new option, --disable-nsec-timestamps, to
4508 avoid using sub-second timestamps on systems that support it. It
4509 can lead to problems, e.g. if your makefile relies on "cp -p".
4510 * README.template: Document the issue with "cp -p".
4512 * config.guess, config.sub: Updated.
