685 2010-07-03 Paul Smith <psmith@gnu.org>
687 * read.c (parse_file_seq): All archive groups must end with ')' as
688 the LAST character in a word. If there is no word ending in ')'

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

755 lowest directory index.
757 * implicit.c (pattern_search): Pass NULL for the index arguments in
758 the VPATH_SEARCH call.
760 * doc/make.texi (Directory Search for Link Libraries): Describe the

847 * implicit.c (pattern_search): Initialize file variables only
848 if we need to parse a rule that requires the second expansion.
850 2009-10-03 Paul Smith <psmith@gnu.org>
852 * make.h: Include <alloca.h> even on systems where __GNUC__ is
853 defined. Not sure why it was done the other way.
854 Requested by David Boyce <dsb@boyski.com>.
856 2009-09-30 Boris Kolpackov <boris@codesynthesis.com>

860 * filedef.h (file):Add the NO_DIAG bitfield.
862 * read.c (eval_makefile): Set the DONTCARE flag in struct dep,

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

911 * doc/make.texi (Double-Colon): Mention that pattern rules with
912 double-colons have a different meaning. Savannah bug #27497.
914 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
916 * configh.dos.template: Remove unconditional definition of
917 SYS_SIGLIST_DECLARED.
918 Include <sys/version.h> because ports of GCC 4.3.0 and later no
919 longer include it, so macros like __DJGPP_MINOR__ are no longer
920 defined automatically.
922 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
923 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
924 instead of using the hardcoded ones.
925 (SUBDIRS): doc subdir added.
926 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
927 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
928 create html formated docs. texi2html may not be ported to DOS.
929 (make.info, make.dvi, make.ps, make.html): Make targets depend on
931 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
932 -I switch to look in ./ instead of ./doc.
933 (html): Target depend on html-recursive instead of make_1.html.
934 (make_1.html): Removed.
935 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
936 (all-recursive): Allow for more than one subdir in the build
938 (mostlyclean-recursive, clean-recursive, distclean-recursive)
939 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
940 (tags-recursive): Allow for more than one subdir in the build
942 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
943 targets. Enter into doc/ to produce the targets.
944 (all-am): $(INFO_DEPS) replaced by info.
946 2009-09-26 Paul Smith <psmith@gnu.org>
948 * read.c (record_files): Use free_ns() to free struct nameseq.
951 * rule.c (freerule): Use free_dep_chain().
953 * read.c (record_files): Free FILENAMES chain for implicit rules.
954 (eval): Static pattern targets go into the string cache.
956 * function.c (string_glob): Free NAME in the nameseq chain.
958 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
960 * implicit.c (pattern_search): Terminate early if we haven't
961 found any rules to try (performance improvement).
963 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
965 * implicit.c (pattern_search): Merge three parallel arrays,
966 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
967 of struct TRYRULE. In the old version the latter two arrays
968 had insufficient length.
970 2009-09-24 Paul Smith <psmith@gnu.org>
972 * implicit.c (pattern_search): Add back support for order-only
973 prerequisites for secondary expansion implicit rules, that were
974 accidentally dropped. If we find a "|", enable order-only mode
975 and set IGNORE_MTIME on all deps that are seen afterward.
976 (pattern_search): Fix memory leaks: for intermediate files where
977 we've already set the file variable and pattern variable sets, be
978 sure to either save or free them as appropriate.
980 2009-09-23 Paul Smith <psmith@gnu.org>
982 Rework the way secondary expansion is stored, for efficiency.
983 This changes secondary expansion so that ONLY WHEN we know we have
984 a possibility of needing secondary expansion, do we defer the
985 secondary expansion. This means more parsing the deps but we use
986 a lot less memory (due to the strcache). Also, this fixes
989 * read.c (eval): Don't parse the dep string here anymore.
990 (record_files): Take the dep argument as an unparsed string. If
991 secondary expansion is enabled AND the prereq string has a '$' in
992 it, then set NEED_2ND_EXPANSION and keep the entire string.
993 Otherwise, parse the dep string here to construct the dep list
994 with the names in the strcache.
996 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
997 duplicate the name string (others are in the strcache).
999 * implicit.c: Remove struct idep and free_idep_chain(): unused.
1000 (struct patdeps): New structure to store prereq information.
1001 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
1002 which prerequisites need expansion, and expand only those.
1004 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
1005 and enter_prereqs(). split_prereqs() takes a fully-expanded string
1006 and splits it into a DEP list, handling order-only prereqs.
1007 (enter_prereqs): This function enters a list of DEPs into the file
1008 database. If there's a stem defined, expand any pattern chars.
1009 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
1010 set. Use the above functions.
1011 (snap_deps): Only perform second expansion on prereqs that need it,
1012 as defined by the NEED_2ND_EXPANSION flag.
1013 (print_prereqs): New function to print the prereqs
1014 (print_file): Call print_prereqs() rather than print inline.
1016 * hash.h (STRING_COMPARE): Take advantage of strcache() by
1018 (STRING_N_COMPARE): Ditto.
1019 (ISTRING_COMPARE): Ditto.
1021 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
1022 (parse_file_seq): Return void*
1023 * read.c (parse_file_seq): Return void*.
1024 (eval): Invoke macroized version of parse_file_seq()
1025 * default.c (set_default_suffixes): Ditto.
1026 * file.c (split_prereqs): Ditto.
1027 * function.c (string_glob): Ditto.
1028 * main.c (main): Ditto.
1029 * rule.c (install_pattern_rule): Ditto.
1031 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
1033 2009-09-16 Paul Smith <psmith@gnu.org>
1035 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
1037 * dep.h: Create alloc_dep() / free_dep() macros.
1039 * implicit.c (pattern_search): Take advantage of the new
1040 parse_file_seq() to add the directory prefix to each prereq.
1042 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
1043 all. Avoid reversing chains. Support adding prefixes.
1044 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
1045 cached/non-cached results.
1046 (eval): Remove multi_glob() & invoke new parse_file_seq().
1047 * rule.c (install_pattern_rule): Ditto.
1048 * main.c (main): Ditto.
1049 * implicit.c (pattern_search): Ditto.
1050 * function.c (string_glob): Ditto.
1051 * file.c (parse_prereqs): Ditto.
1052 * default.c (set_default_suffixes): Ditto.
1054 * variable.c (parse_variable_definition): Don't run off the end of
1055 the string if it ends in whitespace (found with valgrind).
1057 * commands.c (set_file_variables): Keep space for all targets in
1058 $? if -B is given (found with valgrind).
1060 2009-09-15 Paul Smith <psmith@gnu.org>
1062 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
1063 (xcalloc): Add new function.
1064 * make.h: New declarations.
1066 * ar.c (ar_glob_match): New calling method for concat().
1067 * main.c (main): Ditto.
1068 (decode_env_switches): Ditto.
1069 * read.c (eval_makefile): Ditto.
1070 (tilde_expand): Ditto.
1071 (parse_file_seq): Ditto.
1072 * variable.c (target_environment): Ditto.
1073 (sync_Path_environment): Ditto.
1075 * ar.c (ar_glob_match): Use xcalloc().
1076 * dir.c (file_impossible): Ditto.
1077 * file.c (enter_file): Ditto.
1078 * job.c (new_job): Ditto.
1079 * read.c (parse_file_seq): Ditto.
1080 * vmsfunctions.c (opendir): Ditto.
1082 2009-09-14 Rafi Einstein <rafi.einstein@gmail.com> (tiny patch)
1084 * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
1085 inside the loop that looks up environment for PATH.
1087 2009-08-31 Eli Zaretskii <eliz@gnu.org>
1089 * function.c (windows32_openpipe): Update envp after calling
1090 sync_Path_environment.
1092 2009-08-02 Paul Smith <psmith@gnu.org>
1094 * remake.c (notice_finished_file): Ensure file->cmds is not null
1095 before looping through them. Fixes Savannah bug #21824.
1097 * doc/make.texi (Wildcard Examples): Clarify when objects is
1098 wildcard-expanded. Fixes Savannah bug #24509. Patch by Martin Dorey.
1099 (Include): Clarify the behavior of -include.
1100 Fixes Savannah bug #18963.
1102 2009-08-01 Paul Smith <psmith@gnu.org>
1104 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1105 etc. come on the command line. Fixes Savannah bug #27093.
1107 * expand.c (expand_argument): If the argument is large enough use
1108 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1110 * variable.c (do_variable_definition): Avoid using alloca() to
1111 hold values, which can be large. Fixes Savannah bug #23960.
1113 * job.c (new_job): Use memmove() instead of strcpy() since both
1114 pointers are in the same memory block. Fixes Savannah bug #27148.
1115 Patch by Petr Machata.
1117 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1119 * job.c (construct_command_argv_internal): Add "ulimit" and
1120 "unset" to the sh_cmds for Unixy shells.
1122 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1124 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1125 that set make_cv_sys_gnu_glob, so they are also correctly set
1126 when the cache has been populated before.
1128 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1130 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1131 exist, as realpath(3) does where it's supported.
1133 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1135 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1136 (abspath): Support systems that define HAVE_DOS_PATHS (have
1137 drive letters in their file names). Use IS_PATHSEP instead of a
1138 literal '/' comparison. Fixes Savannah bug #26886.
1140 2009-06-14 Paul Smith <psmith@gnu.org>
1142 * remake.c (update_file_1): Remember the original file we marked
1143 as updating, so we can clear that flag again. If we find a target
1144 via vpath, FILE might change.
1145 (check_dep): Ditto. Fixes Savannah bug #13529.
1146 Patch by Reid Madsen <reid.madsen@tek.com>.
1148 2009-06-13 Paul Smith <psmith@gnu.org>
1150 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1151 included by MAKEFILES cannot give default goals.
1152 * read.c (eval): If set_default is not set, pass the no-default-goal
1153 value when we read included makefiles. Fixes Savannah bug #13401.
1155 * ar.c (ar_name): Ensure that targets with empty parens aren't
1156 considered archive member references: archive members must have a
1157 non-empty "member" string. Fixes Savannah bug #18435.
1159 * function.c (string_glob): Rely on multi_glob() to determine
1160 whether files exist or not. Remove call to file_exists_p() which
1161 is not always correct. Fixes Savannah bug #21231.
1162 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1163 then only files that really exist will be returned.
1164 * dep.h: Add new argument to multi_glob().
1165 * rule.c (install_pattern_rule): Ditto.
1166 * read.c (eval): Ditto.
1167 * main.c (main): Ditto.
1168 * implicit.c (pattern_search): Ditto.
1169 * file.c (parse_prereqs): Ditto.
1170 * default.c (set_default_suffixes): Ditto.
1172 2009-06-09 Paul Smith <psmith@gnu.org>
1174 * commands.c (set_file_variables): If always_make_flag is set,
1175 always add the prereq to $?. Fixes Savannah bug #17825.
1177 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1178 to rebuild the deps of all the also_make targets for that file.
1179 Fixes Savannah bug #19108.
1181 * implicit.c (pattern_search): Undo test for is_target, added by
1182 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1183 Rule Search Algorithm". Fixes Savannah bug #17752.
1185 * main.c (clean_jobserver): Clear the jobserver_fds options and
1186 set job_slots to the default when we clean up.
1187 (define_makeflags): Return the new MAKEFLAGS value.
1188 (main): Reset MAKEFLAGS in the environment when we re-exec.
1189 Fixes Savannah bug #18124.
1191 2009-06-08 Paul Smith <psmith@gnu.org>
1193 * read.c (eval): Collapse continuations post-semicolon on target-
1194 specific variables. Fixes Savannah bug #17521.
1196 2009-06-07 Paul Smith <psmith@gnu.org>
1198 * job.c (reap_children): For older systems without waitpid() (are
1199 there any of these left?) run wait(2) inside EINTRLOOP to handle
1200 EINTR errors. Fixes Savannah bug #16401.
1202 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1204 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1206 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1207 not the end, to catch second expansion $(eval ...) defining new
1208 target/prereq relationships during snap_deps.
1209 Fixes Savannah bug #24622.
1211 * read.c (record_files): The second-expansion "f->updating" hack
1212 was not completely correct: if assumed that the target with
1213 commands always had prerequisites; if one didn't then the ordering
1214 was messed up. Fixed for now to use f->updating to decide whether
1215 to preserve the last element in the deps list... but this whole
1216 area of constructing and reversing the deps list is too confusing
1217 and needs to be reworked. Fixes Savannah bug #21198.
1219 2009-06-06 Paul Smith <psmith@gnu.org>
1221 * hash.c (hash_insert): Remove useless test for NULL.
1222 Fixes Savannah bug #21823.
1224 * make.h: Move SET_STACK_SIZE determination to make.h.
1225 * main.c (main): New global variable, STACK_LIMIT, holds the
1226 original stack limit when make was started.
1227 * job.c (start_job_command): Reset the stack limit, if we changed it.
1228 Fixes Savannah bug #22010.
1230 * remake.c (check_dep): Only set the target's state to not-started
1231 if it's not already running. Found this while testing -j10 builds
1232 of glibc: various targets were being rebuilt multiple times.
1233 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1236 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1237 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1240 2009-06-04 Paul Smith <psmith@gnu.org>
1242 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1244 * maintMakefile: Modify access of config and gnulib Savannah
1245 modules to use GIT instead of CVS.
1247 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1248 Fixes Savannah bug #24655.
1250 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1251 this can happen during some invocations of $(eval ...) for example.
1252 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1254 2009-06-02 Paul Smith <psmith@gnu.org>
1256 * configure.in: Check for fileno()
1257 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1258 for the makefile file so invocations of $(shell ...) don't inherit it.
1259 Fixes Savannah bug #24277.
1261 2009-06-01 Paul Smith <psmith@gnu.org>
1263 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1264 expansion was handled incorrectly. Rework the default goal
1265 handling to save the variable only. Remove default_goal_file and
1267 * read.c (eval): Check default_goal_var, not default_goal_name.
1268 * read.c (record_target_var): Don't check default_goal_file here.
1270 2009-05-31 Paul Smith <psmith@gnu.org>
1272 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1273 it, and if the multi_glob() returns nothing (say it expanded to
1274 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1276 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1277 $(and ..) to the reference. Fixes Savannah bug #25694.
1279 * make.1: Be clear that some recipes will be executed even with -n.
1280 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1282 * doc/make.texi (Override Directive): Make more clear how
1283 overrides and appends interact.
1284 Elucidates part of Savannah bug #26207.
1286 * read.c (record_target_var): Don't reset the origin on
1287 target-specific variables; try_variable_definition() will handle
1288 this correctly. Fixes Savannah bug #26207.
1290 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1291 Fixes Savannah bug #25712.
1293 * implicit.c (pattern_search): Keep a pointer to the beginning of
1294 the filename and save that instead of the constructed pointer.
1295 Fixes Savannah bug #26593.
1296 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1298 2009-05-30 Paul Smith <psmith@gnu.org>
1300 * doc/make.texi (Multi-Line): Add a description of the new abilities
1301 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1302 "command sequence" vs. "recipe" syntax.
1303 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1304 after a define, to create variables with those flavors.
1306 2009-05-25 Paul Smith <psmith@gnu.org>
1308 Reworked the parser for variable assignments to allow multiple
1309 modifiers, and in any order. Also allows variable and
1310 prerequisites to be modifier names ('export', 'private', etc.)
1312 * NEWS: Add notes about user-visible changes.
1314 * read.c (struct vmodifiers): Remember what modifiers were seen.
1315 (parse_var_assignment): New function to parse variable assignments.
1316 (eval): Call the new function. Handle variable assignments earlier.
1318 * variable.c (parse_variable_definition): Only parse; don't create var.
1319 (assign_variable_definition): Call parse, then create the var.
1321 2009-05-24 Paul Smith <psmith@gnu.org>
1323 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1324 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1326 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1328 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1329 Fixes Savannah bug #25412.
1331 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1332 prototype for xmalloc.
1333 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1334 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1335 Loop over an array of extensions, instead of duplicating the same
1336 code inline. Use SearchPath followed by CreateFile, instead of
1337 the obsolete OpenFile. Fixes Savannah bug #17277.
1338 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1339 to `find_file'. Fixes Savannah bug #25662.
1341 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1343 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1344 Fixes Savannah bug #20495.
1346 2009-02-28 Ralf Wildenhues <address@hidden>
1348 * doc/make.texi (Instead of Execution): Document interaction of
1349 -t with phony targets.
1351 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1353 Introduce a new keyword "private" which applies to target-specific
1354 variables and prevents their values from being inherited.
1356 * variable.h (struct variable): Add private_var flag to each variable.
1357 Add a flag to specify which list entry switches to the parent target.
1358 * variable.c (define_variable_in_set): Initialize private_var flag.

1373 * function.c (func_foreach): Ditto.
1374 * read.c (eval, record_files): Ditto.
1375 * variable.c (define_variable_in_set): Ditto.
1377 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1379 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1382 * w32/subproc/build.bat (GCCBuild): Likewise.
1384 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1386 * job.c (construct_command_argv_internal): Avoid extra backslash
1387 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1390 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1392 * README.W32.template: Remove obsolete text about non-support for
1393 -jN without Unixy shell. Remove obsolete text about not supplying
1394 Visual Studio project files (we do supply them). Modify text to
1395 prefer GCC builds to MSC builds.
1397 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1399 * doc/make.texi (Empty Targets): Fix typo.
1401 2008-03-27 Paul Smith <psmith@gnu.org>
1403 Fix Savannah bug #22379:
1404 * ar.c (ar_glob_match): Zero the allocated structure.

1411 2008-01-26 Eli Zaretskii <eliz@gnu.org>
1413 * variable.c (target_environment): Don't use shell_var if its
1414 `value' field is NULL.
1416 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1418 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1420 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1421 (TEXINFOS): Value changed to `doc/make.texi'.
1422 (.SUFFIXES): Use .texi instead of .texinfo.
1423 (make.info, make.dvi): Depend on doc/make.texi.
1424 (.texi.info): New target, instead of ".texinfo.info". Change -I
1425 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1426 (.texi): New target, instead of ".texinfo". Change -I switch to
1427 $(MAKEINFO) to look in doc/. Use --no-split.
1428 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1429 switch to $(MAKEINFO) to look in doc/.
1430 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1431 "*.i[0-9][0-9]" (due to --no-split above).

1433 (html, make_1.html): New targets.
1434 (.PHONY): Add "html".

1440 HAVE_DECL_SYS_SIGLIST.
1442 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1443 build does not use child_execute_job.
1445 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1446 export the SHELL environment variable to the child.
1448 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1450 * config.h.W32: Include sys/types.h.
1451 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1453 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH

1467 * remake.c (f_mtime): Print time difference values between 100 and
1468 ULONG_MAX in fixed-point notation rather than in exponention notation.
1470 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1472 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1473 a more complex value than a simple shell: if it's not a default
1474 shell now then expand it and see if is a default shell then.
1476 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1478 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1479 pathnames, with const strings.
1480 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1481 from the template (used for building from CVS, not a dist).
1483 2007-10-10 Paul Smith <psmith@gnu.org>
1485 * make.h: Add a prototype for w32_kill() (change suggested by
1486 Yongwei Wu <wuyongwei@gmail.com>).
1488 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1490 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1491 directories in Path.
1493 2007-09-12 Paul Smith <psmith@gnu.org>

1496 Provided by Diego Biurrun <diego@biurrun.de>
1497 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1498 Provided by Diego Biurrun <diego@biurrun.de>
1500 2007-09-11 Paul Smith <psmith@gnu.org>
1502 * doc/make.texi (Special Variables): Moved this into the "How to
1503 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1504 (MAKEFILE_LIST) No longer a section; this was added into the
1505 "Special Variables" section.
1506 (Rule Introduction): Reference .RECIPEPREFIX.
1507 (Simple Makefile): Ditto.
1508 (Rule Syntax): Ditto.
1509 (Command Syntax): Ditto.
1510 (Error Messages): Ditto.
1512 2007-09-10 Paul Smith <psmith@gnu.org>
1514 * commands.c (print_commands): Don't print an extra line in the
1515 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1517 * read.c (construct_include_path): Add the full string to the cache; we
1518 were chopping the last char.
1520 * NEWS: Announce the .RECIPEPREFIX special variable.
1521 * variable.c (lookup_special_var): Rename from handle_special_var().
1522 (lookup_variable): Call the new name.
1523 (set_special_var): New function: handle setting of special variables.
1524 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1525 (do_variable_definition): Call it.
1526 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1527 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1528 * main.c (main): Create the .RECIPEPREFIX special variable.
1529 * read.c (eval): Remove the cmd_prefix characters from the command
1530 scripts here, so they're not stored in the commands array at all,
1531 rather than waiting and stripping them out during command construction.
1532 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1534 2007-08-15 Paul Smith <psmith@gnu.org>
1536 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1537 file has had the section info removed, so add some to make.texi
1538 before we include it.
1540 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1542 * remake.c (check_dep): Reset the target state for intermediate
1543 files. They might have been considered before but not updated
1544 then (order-only for example) but they will be this time.
1545 Fixes Savannah bug #'s 3330 and 15919.
1547 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1549 Fix Savannah bug #20549:
1550 * function.c (func_shell): Call construct_command_argv with zero
1552 * job.c (construct_command_argv_internal): New argument FLAGS; all
1554 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1556 * job.h (construct_command_argv_internal): Update prototype.
1558 2007-07-13 Paul Smith <psmith@gnu.org>
1560 * file.c (expand_deps): Use variable_buffer as the start of the
1561 buffer, not the original pointer (in case it was reallocated).
1562 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1563 Fixes Savannah bug #20452.
1565 2007-07-04 Paul Smith <psmith@gnu.org>
1567 * (ALL FILES): Update to GPLv3.
1568 * (ALL FILES): Update copyright for 2007.

1574 * maintMakefile: Update Translation Project location.
1576 2007-06-13 Paul Smith <psmith@gnu.org>
1578 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1579 "Expansion of a deferred"
1580 Fixes Savannah bug #20018.
1582 * expand.c (variable_expand_for_file): Preserve the value of
1583 reading_file rather than setting it to 0 at the end.

1586 2007-05-11 Paul Smith <psmith@gnu.org>
1588 * job.c (new_job): Add debug info to specify where make found the
1589 command script it is running to build a target.

1600 Dave Korn <dave.korn@artimi.com>
1602 2007-05-08 Paul Smith <psmith@gnu.org>
1604 Fix Savannah bug #19656:
1606 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1608 * make.h: Change all case-insensitive string compares to use
1609 strcasecmp() (from POSIX). If we don't have that but do have one
1610 of the others, define strcasecmp to be one of those instead. If
1611 we don't have any, declare a prototype for our own version.
1613 * misc.c (strcasecmp): Use this if we can't find any native
1614 case-insensitive string comparison function.
1615 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1616 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1618 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1619 strcasecmp() instead of stricmp().
1620 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1621 instead of strcmpi().
1622 * acinclude.m4: Remove the strcasecmp() check from here.
1624 2007-03-21 Paul Smith <psmith@gnu.org>
1626 * configure.in: Don't turn on case-insensitive file system support
1627 if --disable-... is given. Fixes Savannah bug #19348.
1629 2007-03-19 Paul Smith <psmith@gnu.org>
1631 * ALL: Use the strcache for all file name strings, or other
1632 strings which we will never free. The goal is to save memory by
1633 avoiding duplicate copies of strings. However, at the moment this
1634 doesn't save much memory in most situations: due to secondary
1635 expansion we actually save prerequisite lists twice (once before
1636 the secondary expansion, and then again after it's been parsed
1637 into individual file names in the dep list). We will resolve this
1638 in a future change, by doing the parsing up-front for targets
1639 where secondary expansion is not set.
1641 Moving things into the strcache also allows us to use const
1642 pointers in many more places.
1644 2007-01-03 Paul Smith <psmith@gnu.org>
1646 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1647 the function, not just the first. Fixes Savannah bug #18680.
1649 2006-11-18 Paul Smith <psmith@gnu.org>
1651 * strcache.c (strcache_add_len): Don't allocate a new buffer
1652 unless the string is not already nil-terminated. Technically this
1653 is a violation of the standard, since we may be passed an array
1654 that is not long enough to test one past. However, in make this
1655 is never true since we only use nil-terminated strings or
1656 sub-strings thereof.
1658 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1660 * main.c: New global cmd_prefix, defaults to '\t'.
1661 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1664 * dir.c: Constified.
1665 (dir_contents_file_exists_p): Check for an error return from
1666 readdir(), just in case.
1668 * commands.c: Constified.
1669 * default.c: Constified.
1670 * expand.c: Constified.
1671 * function.c: Partial constification.

1676 * w32/pathstuff.c: Partial constification.
1678 2006-11-16 Eli Zaretskii <eliz@gnu.org>
1680 * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
1681 backslashes and drive letters as absolute.
1683 2006-10-22 Paul Smith <psmith@gnu.org>

1687 2006-10-21 Paul Smith <psmith@gnu.org>
1690 * arscan.c: Constified.
1692 2006-09-30 Paul Smith <psmith@gnu.org>
1694 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1695 point to lastword since the example was updated.
1696 Fixes Savannah bug #16304.
1697 (Secondary Expansion): Correct example description.
1698 Fixes Savannah bug #16468.
1699 (Makefile Contents): Clarify that comments cannot appear within
1700 variable references or function calls.
1701 Fixes Savannah bug #16577.
1702 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1703 Fixes Savannah bug #17701.
1704 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1706 prerequisites. Fixes Savannah bug #17880.
1707 (Rule Syntax): "lise" -> "list"
1708 (Multiple Rules): ... -> @dots{}
1709 (Splitting Lines): ditto.
1711 * remake.c (update_file_1): Prereqs that don't exist should be
1712 considered changed, for the purposes of $?.
1713 Fixes Savannah bug #16051.
1715 * make.1: Remove extraneous "+".

1755 that don't have extended grep.
1756 (cvsclean): Use $(PERL) instead of perl.

1760 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1762 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1763 inner-scope variables don't mask outer-scope variables.

1824 Declare and define sh_chars_sh[].
1826 2006-03-23 Paul D. Smith <psmith@gnu.org>
1828 * configure.in: Look for build.sh.in in $srcdir so it will be
1829 built for remote configurations as well.
1831 * Makefile.am: Make sure to clean up build.sh during distclean.
1832 Fixes Savannah bug #16166.
1834 * misc.c (log_access): Takes a const char *.

1840 * implicit.c (pattern_search): Call set_file_variables only
1841 if we have prerequisites that need second expansion. Fixes
1842 Savannah bug #16140.

1850 make sure I don't forget any).
1852 * main.c (clean_jobserver): Move jobserver cleanup code into a new

1869 (copy_dep_chain): Copy stem.
1870 (free_dep_chain): Use free_dep.
1871 * read.c (record_files): Store stem in the dependency line.
1872 * file.c (expand_deps): Use stem stored in the dependency line. Use
1873 free_dep_chain instead of free_ns_chain.

1886 Fixes Savannah bug #15913.
1888 2006-03-09 Paul Smith <psmith@gnu.org>
1890 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1891 listed non-existent files as changed. Turns out there's a bug in
1892 the Linux kernel builds which means that this change causes
1893 everything to rebuild every time. We will re-introduce this fix
1894 in the next release, to give them time to fix their build system.
1895 Fixes Savannah bug #16002.
1896 Introduces Savannah bug #16051.

1915 * commands.c (set_file_variables): Realloc, not malloc, the static
1916 string values to avoid memory leaks.
1918 * expand.c (recursively_expand_for_file): Only set reading_file to
1919 an initialized value.
1921 * implicit.c (pattern_search): We need to make a copy of the stem
1922 if we get it from an intermediate dep, since those get freed.
1924 * file.c (lookup_file) [VMS]: Don't lowercase special targets that

1931 * job.c (construct_command_argv_internal): Fix last change.
1933 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1934 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1935 the calls to _beginthreadex.
1937 * expand.c (recursively_expand_for_file): Initialize `save' to
1938 prevent compiler warnings.
1940 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1942 * job.c (construct_command_argv_internal): Don't create a temporary

1944 script file stream to text mode.

1948 * variable.c (merge_variable_set_lists): Don't try to merge the
1949 global_setlist. Not only is this useless, but it can lead to
1950 circularities in the linked list, if global_setlist->next in one
1951 list gets set to point to another list which also ends in

1957 Fix for Savannah bug #106.
1959 * expand.c (expanding_var): Keep track of which variable we're
1960 expanding. If no variable is being expanded, it's the same as
1962 * make.h (expanding_var): Declare it.
1963 * expand.c (recursively_expand_for_file): Set expanding_var to the
1964 current variable we're expanding, unless there's no file info in
1965 it (could happen if it comes from the command line or a default
1966 variable). Restore it before we exit.

1978 * read.c (eval): Even if the included filenames expands to the
1979 empty string we still need to free the allocated buffer.
1981 * implicit.c (pattern_search): If we allocated a variable set for
1982 an impossible file, free it.
1983 * variable.c (free_variable_set): New function.
1984 * variable.h: Declare it.
1986 * read.c (read_all_makefiles): Makefile names are kept in the
1987 strcache, so there's never any need to alloc/free them.
1990 * main.c (main): Add "archives" to the .FEATURES variable if
1991 archive support is enabled.

2002 * (ALL FILES): Updated copyright and license notices.
2004 2006-02-10 Paul D. Smith <psmith@gnu.org>
2006 A new internal capability: the string cache is a read-only cache
2007 of strings, with a hash table interface for fast lookup. Nothing
2008 in the cache will ever be freed, so there's no need for reference
2009 counting, etc. This is the beginning of a full solution for
2010 Savannah bug #15182, but for now we only store makefile names here.
2012 * strcache.c: New file. Implement a read-only string cache.
2013 * make.h: Add prototypes for new functions.
2014 * main.c (initialize_global_hash_tables): Initialize the string cache.
2015 (print_data_base): Print string cache stats.
2016 * read.c (eval_makefile): Use the string cache to store makefile
2017 names. Rewrite the string allocation to be sure we free everything.

2021 * dir.c (dir_contents_file_exists_p): Don't opendir if the
2022 directory time stamp didn't change, except on FAT filesystems.

2047 -W, don't overwrite it with the real mtime.

2068 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
2069 the comparison. For 64-bits systems the result of the subtraction
2070 might not fit into an int. Use comparison instead.
2071 Fixes Savannah bug #15534.

2074 the changes made in 3.81 for backslash/newline and SHELL handling.
2076 2006-02-01 Paul D. Smith <psmith@gnu.org>

2096 * remake.c (update_goal_chain): Set g->changed instead of
2097 incrementing it, as it is only 8-bit wide, and could overflow if
2098 many commands got started in update_file.
2100 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
2102 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
2103 MAXIMUM_WAIT_OBJECTS.
2104 (process_wait_for_any_private): Change dimension of handles[]
2105 array to MAXIMUM_WAIT_OBJECTS.
2106 (process_used_slots): New function.
2107 (process_register): Don't register more processes than the
2108 available number of slots.
2109 (process_easy): Don't start new processes if all slots are used up.
2111 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
2112 are already more children than sub_proc.c can handle, behave as if
2113 the load were too high.
2114 (start_job_command): Fix a typo in error message when process_easy
2117 2006-01-14 Eli Zaretskii <eliz@gnu.org>
2119 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
2120 the shell is not sh.exe.
2122 * job.c (create_batch_file): Renamed from create_batch_filename;
2123 all callers changed. Don't close the temporary file; return its
2124 file descriptor instead. New arg FD allows to return the file
2126 (construct_command_argv_internal): Use _fdopen instead of fopen to
2127 open the batch file.
2129 2006-01-04 Paul D. Smith <psmith@gnu.org>
2131 * readme.vms: Updates for case-insensitive VMS file systems from
2132 Hartmut Becker <Hartmut.Becker@hp.com>.
2133 * dir.c (vms_hash): Ditto.
2134 * vmsify.c (copyto): Ditto.
2135 * vmsfunctions.c (readdir): Ditto.
2137 * make.1: Add a section on the exit codes for make.
2139 * doc/make.texi: A number of minor updates to the documentation.
2141 2006-01-03 Paul D. Smith <psmith@gnu.org>
2143 * remake.c (update_file_1): Mark a prerequisite changed if it
2146 * read.c (eval): Be sure to strip off trailing whitespace from the
2147 prerequisites list properly. Also, initialize all fields in
2148 struct dep when creating a new one.
2150 2005-12-28 Paul D. Smith <psmith@gnu.org>
2152 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2153 disable warnings for MSC.
2154 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2156 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2158 * doc/make.texi (Execution): Add a footnote about changes in
2159 handling of backslash-newline sequences. Mention the differences
2160 on MS-DOS and MS-Windows.
2162 * NEWS: More details about building the MinGW port and a pointer
2163 to README.W32. Fix the section name that describes the new
2164 backward-incompatible processing of backslash-newline sequences.
2165 The special processing of SHELL set to "cmd" is only relevant to
2166 MS-Windows, not MS-DOS.
2168 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2170 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2171 to DWORD, to avoid compiler warnings.
2172 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2173 use %ld in format, to avoid compiler warnings.
2175 * doc/make.texi (Special Targets): Fix a typo.
2176 (Appending): Fix cross-reference to Setting.
2177 (Special Variables, Secondary Expansion, File Name Functions)
2178 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2179 periods after a sentence.
2180 (Execution): Add @: after "e.g.".
2181 (Environment): Fix punctuation.
2182 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2183 (Shell Function, Target-specific): Add @: after "vs."
2185 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2187 * read.c (record_target_var): Initialize variable's export field
2188 with v_default instead of leaving it "initialized" by whatever
2189 garbage happened to be on the heap.
2191 2005-12-12 Paul D. Smith <psmith@gnu.org>
2193 * make.1: Fix some display errors and document all existing options.
2194 Patch by Mike Frysinger <vapier@gentoo.org>.
2196 2005-12-11 Paul D. Smith <psmith@gnu.org>
2198 * implicit.c (pattern_search): If 2nd expansion is not set for
2199 this implicit rule, replace the pattern with the stem directly,
2200 and don't re-expand the variable list. Along with the other
2201 .SECONDEXPANSION changes below, fixes bug #13781.
2203 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2205 * implicit.c (pattern_search): Mark other files that this rule
2206 builds as targets so that they are not treated as intermediates
2207 by the pattern rule search algorithm. Fixes bug #13022.
2209 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2211 * remake.c (notice_finished_file): Propagate the change of
2212 modification time to all the double-colon entries only if
2213 it is the last one to be updated. Fixes bug #14334.
2215 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2217 * function.c (func_flavor): Implement the flavor function which
2218 returns the flavor of a variable.
2219 * doc/make.texi (Functions for Transforming Text): Document it.
2220 * NEWS: Add it to the list of new functions.
2222 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2224 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2226 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2227 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2229 2005-10-26 Paul Smith <psmith@gnu.org>
2231 * read.c (record_files): Don't set deps flags if there are no deps.
2232 * maintMakefile: We only need to build the templates when we are
2233 creating a distribution, so don't do it for "all".
2235 2005-10-24 Paul D. Smith <psmith@gnu.org>
2237 Make secondary expansion optional: its enabled by declaring the
2238 special target .SECONDEXPANSION.
2240 * NEWS: Update information on second expansion capabilities.
2241 * doc/make.texi (Secondary Expansion): Document the
2242 .SECONDEXPANSION special target and its behavior.
2243 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2244 prerequisite list was found in a static pattern rule.
2245 (free_dep_chain): Declare a prototype.
2246 * file.c (parse_prereqs): New function: break out some complexity
2248 (expand_deps): If we aren't doing second expansion, replace % with
2249 the stem for static pattern rules. Call the new function.
2250 * filedef.h (parse_prereqs): Declare a prototype.
2251 * implicit.c (pattern_search): Initialize the new staticpattern
2253 * main.c (second_expansion): Declare a global variable to remember
2254 if the special target has been seen. Initialize the new
2255 staticpattern field for prerequisites.
2256 * make.h: Extern for second_expansion.
2257 * misc.c (free_dep_chain): New function: frees a struct dep list.
2258 * read.c (read_all_makefiles): Initialize the staticpattern field.
2259 (eval_makefile): Ditto.
2260 (record_files): Check for the .SECONDEXPANSION target and set
2261 second_expansion global if it's found.
2262 Use the new free_dep_chain() instead of doing it by hand.
2263 Set the staticpattern field for prereqs of static pattern targets.
2265 2005-10-16 Paul D. Smith <psmith@gnu.org>
2267 * main.c (main): Set CURDIR to be a file variable instead of a
2268 default, so that values of CURDIR inherited from the environment
2269 won't override the make value.
2271 2005-09-26 Paul D. Smith <psmith@gnu.org>
2273 * job.c (construct_command_argv_internal): If the line is empty
2274 remember to free the temporary argv strings.
2277 2005-09-16 Paul D. Smith <psmith@gnu.org>
2279 * job.c (start_job_command): The noerror flag is a boolean (single
2280 bit); set it appropriately.
2281 Reported by Mark Eichin <eichin@metacarta.com>
2283 2005-08-29 Paul D. Smith <psmith@gnu.org>
2285 * function.c (func_error): On Windows, output from $(info ...)
2286 seems to come in the wrong order. Try to force it with fflush().
2288 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2290 * read.c (record_files): Move code that sets stem for static
2291 pattern rules out of the if (!two_colon) condition so it is
2292 also executed for two-colon rules. Fixes Savannah bug #13881.
2294 2005-08-08 Paul D. Smith <psmith@gnu.org>
2296 * make.h: Don't test that __STDC__ is non-0. Some compilers
2297 (Windows for example) set it to 0 to denote "ISO C + extensions".
2300 2005-08-07 Paul D. Smith <psmith@gnu.org>
2302 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2303 conditional (slightly different version of a fix from Eli).
2305 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2306 If make is running in parallel without -k and two jobs die in a
2307 row, but not too close to each other, then make will quit without
2308 waiting for the rest of the jobs to die.
2310 * main.c (die): Don't reset err before calling reap_children() the
2311 second time: we still want it to be in the error condition.
2312 * job.c (reap_children): Use a static variable, rather than err,
2313 to control whether or not the error message should be printed.
2315 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2317 * w32/subproc/sub_proc.c: Include signal.h.
2318 (process_pipe_io, process_file_io): Pass a pointer to a local
2319 DWORD variable to GetExitCodeProcess. If the exit code is
2320 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2322 * job.c [WINDOWS32]: Include windows.h.
2323 (main_thread) [WINDOWS32]: New global variable.
2324 (reap_children) [WINDOWS32]: Get the handle for the main thread
2325 and store it in main_thread.
2327 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2328 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2329 doing anything else. When we are done, close the main thread
2330 handle and exit with status 130.
2332 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2334 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2337 * main.c (find_and_set_default_shell): If found a DOSish shell,
2338 set sh_found and the value of default_shell, and report the
2339 findings in debug mode.
2341 * job.c (construct_command_argv_internal): Check unixy_shell, not
2342 no_default_sh_exe, to decide whether to use Unixy or DOSish
2345 * README.W32: Update with info about the MinGW build.
2347 * build_w32.bat: Support MinGW.
2349 * w32/subproc/build.bat: Likewise.
2351 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2352 printing DWORD args.
2354 * function.c (windows32_openpipe): Fix format strings for printing
2357 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2359 (start_job_command): Fix format string for printing the result of
2361 (start_job_command) [WINDOWS32]: Do not define.
2362 (exec_command): Fix format string for printing HANDLE args.
2364 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2365 to avoid compiler warnings.
2366 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2367 (Note: some of these fixes were submitted independently by J. Grant)
2369 2005-07-30 J. Grant <jg@jguk.org>
2371 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2372 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2373 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2375 2005-07-15 Paul Smith <psmith@gnu.org>
2377 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2378 we don't have a POSIX shell, then revert to the old
2379 backslash-newline behavior (where they are stripped).
2382 2005-07-08 Paul D. Smith <psmith@gnu.org>
2384 * config.h.W32.template: Reorder to match the standard config.h,
2385 for easier comparisons.
2386 From J. Grant <jg@jguk.org>
2388 * maintMakefile: Remove .dep_segment before overwriting it, in
2389 case it's not writable or noclobber is set.
2390 * expand.c (variable_expand_string): Cast result of pointer
2391 arithmetic to avoid a warning.
2392 * main.c (switches): Add full-fledged final initializer.
2394 2005-07-06 Paul D. Smith <psmith@gnu.org>
2396 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2397 * signame.c (strsignal): If we found _sys_siglist[] or
2398 __sys_siglist[] use those instead of sys_siglist[].
2399 From Albert Chin <china@thewrittenword.com>
2401 2005-07-04 Paul D. Smith <psmith@gnu.org>
2403 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2404 globfree(); set up to use the GNU versions.
2405 From Martin Zinser <zinser@zinser.no-ip.info>
2407 2005-07-03 Paul D. Smith <psmith@gnu.org>
2409 From J. Grant <jg@jguk.org>:
2411 * README.W32.template: Update the Windows and tested MSVC versions.
2412 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2413 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2414 * build_w32.bat: Ditto.
2415 * w32/subproc/build.bat: Ditto.
2417 2005-06-28 Paul D. Smith <psmith@gnu.org>
2419 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2420 declaration was checked but not present.
2422 2005-06-27 Paul D. Smith <psmith@gnu.org>
2424 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2425 to unsigned long. Fixes Savannah bug #13550.
2427 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2428 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2429 Fixes Savannah bug #13551.
2431 2005-06-26 Paul D. Smith <psmith@gnu.org>
2433 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2434 it if ANSI_STRING is not set.
2436 2005-06-25 Paul D. Smith <psmith@gnu.org>
2438 * read.c (eval): If no filenames are passed to any of the
2439 "include" variants, don't print an error.
2440 * doc/make.texi (Include): Document this.
2441 Fixes Savannah bug #1761.
2443 * job.c (construct_command_argv_internal): Sanitize handling of
2444 backslash/newline pairs according to POSIX: that is, keep the
2445 backslash-newline in the command script, but remove a following
2446 TAB character, if present. In the fast path, make sure that the
2447 behavior matches what the shell would do both inside and outside
2448 of quotes. In the slow path, quote the backslash and put a
2449 literal newline in the string.
2450 Fixes Savannah bug #1332.
2451 * doc/make.texi (Execution): Document the new behavior and give
2453 * NEWS: Make a note of the new behavior.
2455 * make.h [WINDOWS32]: #include <direct.h>.
2456 Fixes Savannah bug #13478.
2458 * remake.c (name_mtime): If the stat() of a file fails and the -L
2459 option was given and the file is a symlink, take the best mtime of
2460 the symlink we can get as the mtime of the file and don't fail.
2461 Fixes Savannah bug #13280.
2463 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2464 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2465 inside a variable reference. Make this function static as it's
2467 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2468 parsing an unexpanded line looking for semicolons.
2469 Fixes Savannah bug #1454.
2470 * misc.c (remove_comments): Move this to read.c and make it static
2471 as it's only used there. Call find_char_unquote() with new arg.
2472 * make.h: Remove prototypes for find_char_unquote() and
2473 remove_comments() since they're static now.
2475 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2476 its export flag and obtain its value. When we need to re-exec,
2477 increment the value and add it into the environment.
2478 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2479 * NEWS: Mention MAKE_RESTARTS.
2480 * main.c (always_make_set): New variable. Change the -B option to
2481 set this one instead.
2482 (main): When checking makefiles, only set always_make_flag if
2483 always_make_set is set AND the restarts flag is 0. When building
2484 normal targets, set it IFF always_make_set is set.
2485 (main): Avoid infinite recursion with -W, too: only set what-if
2486 files to NEW before we check makefiles if we've never restarted
2487 before. If we have restarted, set what-if files to NEW _after_ we
2489 Fixes Savannah bug #7566:
2491 2005-06-17 Paul D. Smith <psmith@gnu.org>
2493 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2494 in the prerequisites list.
2496 2005-06-12 Paul D. Smith <psmith@gnu.org>
2498 Fix Savannah bug # 1328.
2500 * configure.in: Check for atexit().
2501 * misc.c (close_stdout): Test stdout to see if writes to it have
2502 failed. If so, be sure to exit with a non-0 error code. Based on
2503 code found in gnulib.
2504 * make.h: Prototype.
2505 * main.c (main): Install close_stdout() with atexit().
2507 2005-06-10 Paul D. Smith <psmith@gnu.org>
2509 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2511 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2512 headers; make vmsWaitForChildren() static; extern vmsify().
2513 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2514 Don't create child_execute_job() here (it's in vmsjobs.c).
2515 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2517 2005-06-09 Paul D. Smith <psmith@gnu.org>
2519 * variable.c (push_new_variable_scope): File variables point
2520 directly to the global_setlist variable. So, inserting a new
2521 scope in front of that has no effect on those variables: they
2522 don't go through current_variable_set_list. If we're pushing a
2523 scope and the current scope is global, push it "the other way" so
2524 that the new setlist is in the global_setlist variable, and
2525 next points to a new setlist with the global variable set.
2526 (pop_variable_scope): Properly undo a push with the new
2528 Fixes Savannah bug #11913.
2530 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2532 * job.c (reap_children): Don't die of the command failed but
2533 the dontcare flag is set. Fixes Savannah bug #13216.
2535 * implicit.c (pattern_search): When creating a target from
2536 an implicit rule match, lookup pattern target and set precious
2537 flag in a newly created target. Fixes Savannah bug #13218.
2539 2005-05-13 Paul D. Smith <psmith@gnu.org>
2541 Implement "if... else if... endif" syntax.
2543 * read.c (eval): Push all checks for conditional words ("ifeq",
2544 "else", etc.) down into the conditional_line() function.
2545 (conditional_line): Rework to allow "else if..." clause. New
2546 return value -2 for lines which are not conditionals. The
2547 ignoring flag can now also be 2, which means "already parsed a
2548 true branch". If that value is seen no other branch of this
2549 conditional can be considered true. In the else parsing if there
2550 is extra text after the else, invoke conditional_line()
2551 recursively to see if it's another conditional. If not, it's an
2552 error. If so, raise the conditional value to this level instead
2553 of creating a new conditional nesting level. Special check for
2554 "else" and "endif", which aren't allowed on the "else" line.
2555 * doc/make.texi (Conditional Syntax): Document the new syntax.
2557 2005-05-09 Paul D. Smith <psmith@gnu.org>
2559 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2560 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2561 recurses to the w32 directory, even on non-Windows systems. Use
2562 the method suggested in the automake manual.
2563 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2564 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2566 2005-05-07 Paul D. Smith <psmith@gnu.org>
2568 * main.c (die): If we're dying with a fatal error (not that a
2569 command has failed), write back any leftover tokens before we go.
2571 * job.c (set_child_handler_action_flags): If there are jobs
2572 waiting for the load to go down, set an alarm to go off in 1
2573 second. This allows us to wake up from a potentially long-lasting
2574 read() and start a new job if the load has gone down. Turn it off
2576 (job_noop): Dummy signal handler function.
2577 (new_job): Invoke it with the new semantics.
2579 * docs/make.texi: Document secondary expansion. Various cleanups
2582 2005-05-03 Paul D. Smith <psmith@gnu.org>
2584 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2585 the targets which are to ultimately be made are called "goals";
2586 see the GNU make manual. Also, MAKECMDGOALS, etc.
2588 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2589 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2590 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2592 2005-05-02 Paul D. Smith <psmith@gnu.org>
2594 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2595 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2596 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2597 functions to vmsjobs.c. #include it into jobs.c.
2599 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2600 jobserver tokens. I found that this happens when an exported
2601 recursive variable contains a $(shell ...) function reference: in
2602 this situation we could "forget" to write back a token.
2604 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2605 we have. It's not reliable to depend on the number of children in
2606 our linked list so keep a separate count.
2607 (new_job): Check jobserver_tokens rather than children &&
2608 waiting_jobs. Increment jobserver_tokens when we get one.
2609 (free_child): If jobserver_tokens is 0, internal error. If it's
2610 >1, write a token back to the jobserver pipe (we don't write a
2611 token for the "free" job). Decrement jobserver_tokens.
2613 * main.c: Add variable master_job_slots.
2614 (main): Set it to hold the number of jobs requested if we're the
2615 master process, when using the jobserver.
2616 (die): Sanity checks: first test jobserver_tokens to make sure
2617 this process isn't holding any tokens we didn't write back.
2618 Second, if master_job_slots is set count the tokens left in the
2619 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2621 2005-04-24 Paul D. Smith <psmith@gnu.org>
2623 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2624 with -l# can lose jobserver tokens, because waiting jobs are not
2625 consulted properly when checking for the "free" token.
2627 * job.c (free_child): Count waiting_jobs as having tokens.
2628 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2629 handle jobs waiting for the load to drop.
2631 2005-04-23 Paul D. Smith <psmith@gnu.org>
2633 * main.c (main): Be careful to not core if a variable setting in
2634 the environment doesn't contain an '='. This is illegal but can
2635 happen in broken setups.
2636 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2638 2005-04-12 Paul D. Smith <psmith@gnu.org>
2640 The second expansion feature causes significant slowdown. Timing
2641 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2642 read the makefile before the feature, to 11+s to do the same
2643 operations after the feature. Additionally, memory usage
2644 increased drastically. To fix this I added some intelligence that
2645 avoids the overhead of the second expansion unless it's required.
2647 * dep.h: Add a new boolean field, need_2nd_expansion.
2649 * read.c (eval): When creating the struct dep for the target,
2650 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2651 (record_files): If there's a "%" in a static pattern rule, it gets
2652 converted to "$*" so set need_2nd_expansion to 1.
2654 * file.c (expand_deps): Rework to be more efficient. Only perform
2655 initialize_file_variables(), set_file_variables(), and
2656 variable_expand_for_file() if the need_2nd_expansion is set.
2658 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2659 (pattern_search): Ditto.
2660 * main.c (handle_non_switch_argument): Ditto.
2662 * read.c (read_all_makefiles): Ditto.
2663 (eval_makefile): Ditto.
2665 2005-04-07 Paul D. Smith <psmith@gnu.org>
2667 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2668 * variable.c (sync_Path_environment): Ditto.
2669 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2671 * main.c (main): Define the .FEATURES variable.
2672 * NEWS: Announce .FEATURES.
2673 * doc/make.texi (Special Variables): Document .FEATURES.
2675 * remake.c (check_dep): If a file is .PHONY, update it even if
2676 it's marked intermediate. Fixes Savannah bug #12331.
2678 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2680 * file.c (expand_deps): Factor out the second expansion and
2681 prerequisite line parsing logic from snap_deps().
2683 * file.c (snap_deps): Use expand_deps(). Expand and parse
2684 prerequisites of the .SUFFIXES special target first. Fixes
2685 Savannah bug #12320.
2687 2005-03-13 Paul D. Smith <psmith@gnu.org>
2689 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2692 2005-03-11 Paul D. Smith <psmith@gnu.org>
2694 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2695 available, not undefined (from Earnie Boyd).
2697 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2699 * implicit.c (pattern_search): Mark an intermediate target as
2700 precious if it happened to be a prerequisite of some (other)
2701 target. Fixes Savannah bug #12267.
2703 2005-03-09 Paul D. Smith <psmith@gnu.org>
2705 * read.c (eval_makefile): Add alloca(0).
2706 (eval_buffer): Ditto.
2708 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2710 * main.c (main): Use o_file instead of o_default when defining
2711 the .DEFAULT_TARGET special variable.
2712 * read.c (eval): Use define_variable_global() instead of
2713 define_variable() when setting new value for the .DEFAULT_TARGET
2714 special variable. Fixes Savannah bug #12266.
2716 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2718 * imlicit.c (pattern_search): Mark files for which an implicit
2719 rule has been found as targets. Fixes Savannah bug #12202.
2721 2005-03-04 Paul D. Smith <psmith@gnu.org>
2724 * doc/make.texi (Automatic Variables): Document $|.
2726 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2728 * read.c (record_files): Instead of substituting % with
2729 actual stem value in dependency list replace it with $*.
2730 This fixes stem triple expansion bug.
2732 * implicit.c (pattern_search): Copy stem to a separate
2733 buffer and make it a properly terminated string. Assign
2734 this buffer instead of STEM (which is not terminated) to
2735 f->stem. Instead of substituting % with actual stem value
2736 in dependency list replace it with $*. This fixes stem
2737 triple expansion bug.
2739 2005-03-01 Paul D. Smith <psmith@gnu.org>
2741 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2742 on Windows, as it takes a handle not a pid. Just exit.
2743 Fix from patch #3679, provided by Alessandro Vesely.
2745 * configure.in: Update check for sys_siglist[] from autoconf manual.
2746 * signame.c (strsignal): Update to use the new autoconf macro.
2748 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2750 * read.c (record_files): Add a check for the list of prerequisites
2751 of a static pattern rule being empty. Fixes Savannah bug #12180.
2753 2005-02-28 Paul D. Smith <psmith@gnu.org>
2755 * doc/make.texi (Text Functions): Update docs to allow the end
2756 ordinal for $(wordlist ...) to be 0.
2757 * function.c (func_wordlist): Fail if the start ordinal for
2758 $(wordlist ...) is <1. Matches documentation.
2759 Resolves Savannah support request #103195.
2761 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2762 previously we were stopping when !-q, exactly the opposite. This
2763 has been wrong since version 1.34, in 1994!
2764 (update_file): If we got an error don't break out to run more
2765 double-colon rules: just return immediately.
2766 Fixes Savannah bug #7144.
2768 2005-02-27 Paul D. Smith <psmith@gnu.org>
2770 * misc.c (end_of_token): Make argument const.
2771 * make.h: Update prototype.
2773 * function.c (abspath, func_realpath, func_abspath): Use
2774 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2775 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2776 * read.c (record_files): Ditto.
2777 * variable.c (do_variable_definition): Ditto.
2779 * function.c (func_error): Create a new function $(info ...) that
2780 simply prints the message to stdout with no extras.
2781 (function_table_init): Add new function to the table.
2782 * NEWS: Add $(info ...) reference.
2783 * doc/make.texi (Make Control Functions): Document it.
2785 New feature: if the system supports symbolic links, and the user
2786 provides the -L/--check-symlink-time flag, then use the latest
2787 mtime between the symlink(s) and the target file.
2789 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2790 readlink(). If both are available, define MAKE_SYMLINKS.
2791 * main.c: New variable: check_symlink_flag.
2792 (usage): Add a line for -L/--check-symlink-times to the help string.
2793 (switches): Add -L/--check-symlink-times command line argument.
2794 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2795 print a warning and disable it again.
2796 * make.h: Declare check_symlink_flag.
2797 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2798 if the file is a symlink then check each link in the chain and
2799 choose the NEWEST mtime we find as the mtime for the file. The
2800 newest mtime might be the file itself!
2801 * NEWS: Add information about this new feature.
2802 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2804 Avoid core dumps described in Savannah bug # 12124:
2806 * file.c: New variable snapped_deps remember whether we've run
2808 (snap_deps): Set it.
2809 * filedef.h: Extern it.
2810 * read.c (record_files): Check snapped_deps; if it's set then
2811 we're trying to eval a new target/prerequisite relationship from
2812 within a command script, which we don't support. Fatal.
2814 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2816 Implementation of the .DEFAULT_TARGET special variable.
2818 * read.c (eval): If necessary, update default_target_name when
2820 * read.c (record_files): Update default_target_file if
2821 default_target_name has changed.
2822 * main.c (default_target_name): Define.
2823 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2824 default_target_name is set use default_target_file as a root
2826 * filedef.h (default_target_name): Declare.
2827 * dep.h (free_dep_chain):
2828 * misc.c (free_dep_chain): Change to operate on struct nameseq
2829 and change name to free_ns_chain.
2830 * file.c (snap_deps): Update to use free_ns_chain.
2832 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2834 Implementation of the second expansion in explicit rules,
2835 static pattern rules and implicit rules.
2837 * read.c (eval): Refrain from chopping up rule's dependencies.
2838 Store them in a struct dep as a single dependency line. Remove
2839 the code that implements SySV-style automatic variables.
2841 * read.c (record_files): Adjust the code that handles static
2842 pattern rules to expand all percents instead of only the first
2843 one. Reverse the order in which dependencies are stored so that
2844 when the second expansion reverses them again they appear in
2845 the makefile order (with some exceptions, see comments in
2846 the code). Remove the code that implements SySV-style automatic
2849 * file.c (snap_deps): Implement the second expansion and chopping
2850 of dependency lines for explicit rules.
2852 * implicit.c (struct idep): Define an auxiliary data type to hold
2853 implicit rule's dependencies after stem substitution and
2856 * implicit.c (free_idep_chain): Implement.
2858 * implicit.c (get_next_word): Implement helper function for
2859 parsing implicit rule's dependency lines into words taking
2860 into account variable expansion requests. Used in the stem
2863 * implicit.c (pattern_search): Implement the second expansion
2864 for implicit rules. Also fixes bug #12091.
2866 * commands.h (set_file_variables): Declare.
2867 * commands.c (set_file_variables): Remove static specifier.
2869 * dep.h (free_dep_chain): Declare.
2870 * misc.c (free_dep_chain): Implement.
2872 * variable.h (variable_expand_for_file): Declare.
2873 * expand.c (variable_expand_for_file): Remove static specifier.
2875 * make.h (strip_whitespace): Declare.
2876 * function.c (strip_whitespace): Remove static specifier.
2878 2005-02-26 Paul D. Smith <psmith@gnu.org>
2880 * main.c (main): Check for ferror() when reading makefiles from stdin.
2881 Apparently some shells in Windows don't close pipes properly and
2884 2005-02-24 Jonathan Grant <jg@jguk.org>
2886 * configure.in: Add MinGW configuration options, and extra w32 code
2888 * Makefile.am: Add MinGW configuration options, and extra w32 code
2890 * main.c: Determine correct program string (after last \ without .exe).
2891 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2893 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2894 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2895 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2896 environment support.
2898 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2900 * function.c (func_shell): When initializing error_prefix, check
2901 that reading file name is not null. This fixes long-standing
2902 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2904 2005-02-09 Paul D. Smith <psmith@gnu.org>
2906 * maintMakefile: Update the CVS download URL to simplify them.
2907 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2908 downloading the .texi files from Savannah now.
2910 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2912 * main.c (handle_non_switch_argument): Only add variables to
2913 command_variables if they're not already there: duplicate settings
2914 waste space and can be confusing to read.
2916 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2917 this header is never included by non-WINDOWS32 code, and it
2918 requires <config.h> to define which isn't always included first.
2920 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2921 testing MINGW32 versions.
2923 * main.c (log_working_directory): flush stdout to be sure the WD
2924 change is printed before any stderr messages show up.
2926 2005-02-01 Paul D. Smith <psmith@gnu.org>
2928 * maintMakefile (po_repo): Update the GNU translation site URL.
2930 2004-12-01 Paul D. Smith <psmith@gnu.org>
2932 * main.c (main): Change char* env_shell to struct variable shell_var.
2933 * variable.c (target_environment): Use new shell_var.
2935 2004-11-30 Paul D. Smith <psmith@gnu.org>
2937 * configure.in: The old way we avoided creating build.sh from
2938 build.sh.in before build.sh.in exists doesn't work anymore; we
2939 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2940 the help!). This also keeps automake from complaining.
2941 * Makefile.am (README): Add a dummy target so automake won't
2942 complain that this file doesn't exist when we checkout from CVS.
2943 * maintMakefile (.dep_segment): Rewrite this rule since newer
2944 versions of automake don't provide DEP_FILES.
2946 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2948 Implementation of `realpath' and `abspath' built-in functions.
2950 * configure.in: Check for realpath.
2951 * function.c (abspath): Return an absolute file name that does
2952 not contain any `.' or `..' components, nor repeated `/'.
2953 * function.c (func_abspath): For each name call abspath.
2954 * function.c (func_realpath): For each name call realpath
2955 from libc or delegate to abspath if realpath is not available.
2956 * doc/make.texi (Functions for File Names): Document new functions.
2957 * doc/make.texi (Quick Reference): Ditto.
2959 2004-11-28 Paul D. Smith <psmith@gnu.org>
2961 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2962 arguments. Fixes bug #10252.
2964 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2966 * main.c (main): Set SHELL to v_noexport by default. Remember the
2967 original environment setting of SHELL in the env_shell variable.
2968 * main.h: Export new env_shell variable.
2969 * variable.c (target_environment): If we find a v_noexport
2970 variable for SHELL, add a SHELL variable with the env_shell value.
2971 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2972 * doc/make.texi (Variables/Recursion): Ditto.
2974 2004-11-28 Paul D. Smith <psmith@gnu.org>
2976 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2977 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2978 Patch by Alessandro Vesely.
2980 2004-11-12 Paul D. Smith <psmith@gnu.org>
2982 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2983 the command line if it's inside a string.
2984 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2986 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2988 * function.c (func_lastword): New function: return last word
2989 from the list of words.
2990 * doc/make.texi: Document $(lastword ). Fix broken links in
2991 Quick Reference section.
2993 2004-10-06 Paul D. Smith <psmith@gnu.org>
2995 Apply patch from Alessandro Vesely, provided with bug # 9748.
2996 Fix use of tmpnam() to work with Borland C.
2998 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2999 construction of a temporary filename, and call new function
3000 create_batch_filename().
3001 (create_batch_filename) [WINDOWS32]: New function to create a
3004 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
3006 * read.c (record_target_var): Expand simple pattern-specific
3008 * variable.c (initialize_file_variables): Do not expand simple
3009 pattern-specific variable.
3011 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
3013 * remake.c (update_file_1): When rebuilding makefiles inherit
3014 dontcare flag from a target that triggered update.
3016 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
3018 * variable.c (initialize_file_variables): Mark pattern-specific
3019 variable as a per-target and copy export status.
3021 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
3023 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
3025 * implicit.c (pattern_search): When considering an implicit rule's
3026 prerequisite check that it is actually a target rather then
3027 just an entry in the file hashtable.
3029 2004-09-21 Paul D. Smith <psmith@gnu.org>
3031 * read.c (readstring): Fix some logic errors in backslash handling.
3032 (eval): Remove some unnecessary processing in buffer handling.
3033 (record_target_var): Assert that parse_variable_definition() succeeded.
3034 Reported by: Markus Mauhart <qwe123@chello.at>.
3036 * misc.c: Removed the sindex() function. All instances of this
3037 function were trivially replaceable by the standard strstr()
3038 function, and that function will always have better (or certainly
3039 no worse) performance than the very simple-minded algorithm
3040 sindex() used. This can matter with complex makefiles.
3041 * make.h: Remove the prototype for sindex().
3042 * function.c (subst_expand): Convert sindex() call to strstr().
3043 This means we no longer need to track the TLEN value so remove that.
3044 (func_findstring): Convert sindex() to strstr().
3045 * commands.c (chop_commands): Convert sindex() calls to strstr().
3046 Suggested by: Markus Mauhart <qwe123@chello.at>.
3048 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
3049 idea behind Savannah Patch #3144 from david.baird@homemail.com.
3050 If SHELL is set to CMD.EXE then assume it's batch-mode and
3051 non-unixy. I wrote the code differently from the patch, though,
3052 to make it safer. This also resolves bug #9174.
3054 2004-09-20 Paul D. Smith <psmith@gnu.org>
3056 * expand.c (variable_expand_string): Modify to invoke
3057 patsubst_expand() instead of subst_expand(); the latter didn't
3058 handle suffix patterns correctly.
3059 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
3060 was used only from variable_expand_string() and is no longer used
3062 (func_subst): Ditto, on call to subst_expand().
3063 (patsubst_expand): Require the percent pointers to point to the
3064 character after the %, not to the % itself.
3065 * read.c (record_files): New call criteria for patsubst_expand().
3066 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
3067 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
3069 2004-09-19 Paul D. Smith <psmith@gnu.org>
3071 * function.c (subst_expand): Fix a check in by_word: look for a
3072 previous blank if we're beyond the beginning of the string, not
3073 the beginning of the word.
3074 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3076 2004-05-16 Paul D. Smith <psmith@gnu.org>
3078 * remake.c (update_goal_chain): Change the argument specifying
3079 whether we're rebuilding makefiles to be a global variable,
3080 REBUILDING_MAKEFILES.
3081 (complain): Extract the code that complains about no rules to make
3082 a target into a separate function.
3083 (update_file_1): If we tried to rebuild a file during the makefile
3084 rebuild phase and it was dontcare, then no message was printed.
3085 If we then try to build the same file during the normal build,
3086 print a message this time.
3087 (remake_file): Don't complain about un-remake-able files when
3088 we're rebuilding makefiles.
3090 2004-05-11 Paul D. Smith <psmith@gnu.org>
3092 * job.c (construct_command_argv_internal): OS/2 patches from
3093 Andreas Buening <andreas.buening@nexgo.de>.
3095 2004-05-10 Paul D. Smith <psmith@gnu.org>
3097 * remake.c (update_file): Don't walk the double-colon chain unless
3098 this is a double-colon rule. Fix suggested by Boris Kolpackov
3099 <boris@kolpackov.net>.
3101 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3102 * readme.vms: New section describing OpenVMS support and issues.
3103 * default.c (default_variables): Add support for IA64.
3104 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3105 without some privilege aborts make with the error
3106 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3107 pressing Ctrl+Y and the input device is no terminal. The change
3108 catches this error and just continues.
3110 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3112 2004-04-25 Paul D. Smith <psmith@gnu.org>
3114 * commands.c (set_file_variables): Set $< properly in the face of
3115 order-only prerequisites.
3116 Patch from Boris Kolpackov <boris@kolpackov.net>
3118 2004-04-21 Bob Byrnes <byrnes@curl.com>
3120 * main.c (main): Notice failures to remake makefiles.
3122 2004-03-28 Paul D. Smith <psmith@gnu.org>
3124 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3126 * job.c: No default shell for RISC OS.
3127 (load_too_high): Hard-code the return to 1.
3128 (construct_command_argv_internal): No sh_chars or sh_cmds.
3129 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3131 2004-03-20 Paul D. Smith <psmith@gnu.org>
3133 * variable.c (do_variable_definition): Don't append from the
3134 global set if a previous non-appending target-specific variable
3135 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3138 * expand.c (reference_variable): Don't give up on variables with
3139 no value that have the target-specific append flag set: they might
3140 have a value after all. Reported by Oliver Schmidt
3141 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3142 <nikulin@dx1cmd.inp.nsk.su>.
3144 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3145 refer to absolute pathnames in directories that don't exist: some
3146 portion of the makefile could create those directories before we
3147 match the pattern. Fixes bugs #775 and #108.
3149 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3151 * main.c (main): Free makefile_mtimes if we have any.
3152 * README.W32.template: Update documentation for the current status
3153 of the MS-Windows port.
3154 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3155 environment variable is sometimes already defined which causes the
3157 * main.c (debug_signal_handler): Only define this function if
3158 SIGUSR1 is available.
3160 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3162 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3163 * README.OS2.template: Documentation updates.
3164 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3165 link line for safety.
3166 * maintMakefile (build.sh.in): Remove an extraneous ")".
3167 * job.c (child_execute_job): Close saved FDs.
3168 * job.c (exec_command) [OS/2]: exec_command(): If the command
3169 can't be exec'ed and if the shell is not Unix-sh, then try again
3170 with argv = { "cmd", "/c", ... }. Normally, this code is never
3171 reached for the cmd shell unless the command really doesn't exist.
3172 (construct_command_argv_internal) [OS/2]: The code for cmd
3173 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3174 The CMD builtin commands are case insensitive so use strcasecmp().
3176 2004-03-19 Paul D. Smith <psmith@gnu.org>
3178 * read.c (do_define): Re-order line counter increment so the count
3179 is accurate (we were losing one line per define). Reported by
3180 Dave Yost <Dave@Yost.com>.
3182 2004-03-06 Paul D. Smith <psmith@gnu.org>
3184 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3186 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3187 * misc.c (message,error,fatal): Ditto.
3188 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3189 * config.h.W32.template: Ditto.
3190 * config.h-vms.template: Ditto.
3191 * config.ami.template: Ditto.
3193 2004-03-04 Paul D. Smith <psmith@gnu.org>
3195 * README.template: Add a note about broken /bin/sh on SunOS
3196 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3198 * misc.c (message, error, fatal): Don't use "..." if we're using
3199 varargs. ansi2knr should handle this but it doesn't work: it
3200 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3201 done. On many systems (SunOS for example) va_dcl is a #define.
3202 So, force the use of the non-"..." version on pre-ANSI compilers.
3204 * maintMakefile (sign-dist): Create some rules to help automate
3205 the new GNU ftp upload method.
3207 2004-02-24 Paul D. Smith <psmith@gnu.org>
3209 * config.h.W32.template: Add HAVE_STDARG_H
3210 * config.h-vms.template: Ditto.
3211 * config.ami.template: Ditto.
3213 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3215 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3216 * build_w32.bat: Remove extra "+".
3218 2004-02-23 Paul D. Smith <psmith@gnu.org>
3220 * make.h: Create an UNUSED macro to mark unused parameters.
3221 * (many): Clean up warnings by applying UNUSED, fixing
3222 signed/unsigned incompatibilities, etc.
3224 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3226 * filedef.h: Name the command_state enumeration.
3227 * file.c (set_command_state): Use the enumeration in the function
3230 * configure.in: Explicitly set SET_MAKE to empty, to disable
3231 MAKE=make even when no make already exists. Fix bug #3823.
3233 2004-02-22 Paul D. Smith <psmith@gnu.org>
3235 * maintMakefile: Perl script to clean up all non-CVS files. Use
3236 it on all the subdirectories for the cvs-clean target.
3238 * main.c (decode_switches): Require non-empty strings for all our
3239 string command-line options. Fixes Debian bug # 164165.
3241 * configure.in: Check for stdarg.h and varargs.h.
3242 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3243 for printing messages.
3244 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3249 A number of patches for OS/2 support from Andreas Buening
3250 <andreas.buening@nexgo.de>:
3252 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3253 disable the SIGCHLD handler.
3254 (reap_children) [OS/2]: Remove special handling of job_rfd.
3255 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3256 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3257 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3258 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3259 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3262 2004-02-21 Paul D. Smith <psmith@gnu.org>
3264 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3265 <mail@kristov.de> reports that if process_begin() fails we don't
3266 handle the error condition correctly in all cases.
3267 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3268 to have a newline on the message.
3270 * job.c (construct_command_argv_internal): Add "test" to UNIX
3271 sh_cmds[]. Fixes Savannah bug # 7606.
3273 2004-02-04 Paul D. Smith <psmith@gnu.org>
3275 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3276 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3277 Hartmut Becker <Hartmut.Becker@hp.com>.
3279 2004-01-21 Paul D. Smith <psmith@gnu.org>
3281 * job.c (load_too_high): Implement an algorithm to control the
3282 "thundering herd" problem when using -l to control job creation
3283 via the load average. The system only recomputes the load once a
3284 second but we can start many jobs in a second. To solve this we
3285 keep track of the number of jobs started in the last second and
3286 apply a weight to try to guess what a correct load would be.
3287 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3288 Also fixes bug #4693.
3289 (reap_children): Decrease the job count for this second.
3290 (start_job_command): Increase the job count for this second.
3292 * read.c (conditional_line): Expand the text after ifn?def before
3293 checking to see if it's a single word. Fixes bug #7257.
3295 2004-01-09 Paul D. Smith <psmith@gnu.org>
3297 * file.c (print_file): Recurse to print all targets in
3298 double-colon rules. Fixes bug #4518, reported (with patch) by
3299 Andrew Chatham <chatham@google.com>.
3301 2004-01-07 Paul D. Smith <psmith@gnu.org>
3303 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3304 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3305 AC_FUNC_SETVBUF_REVERSED.
3307 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3308 (MAKE Variable): Fix Savannah bug #4898.
3310 * job.c (construct_command_argv_internal): Add "!" to the list of
3311 shell escape chars. POSIX sh allows it to appear before a
3312 command, to negate the exit code. Fixes bug #6404.
3314 * implicit.c (pattern_search): When matching an implicit rule,
3315 remember which dependencies have the ignore_mtime flag set.
3316 Original fix provided in Savannah patch #2349, by Benoit
3317 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3319 2003-11-22 Paul D. Smith <psmith@gnu.org>
3321 * README.W32.template (Outputs): Clarification on -j with
3322 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3325 2003-11-02 Paul D. Smith <psmith@gnu.org>
3327 * function.c (func_if): Strip all the trailing whitespace from the
3328 condition, then don't expand it. Fixed bug # 5798.
3330 * expand.c (recursively_expand_for_file): If we're expanding a
3331 variable with no file context, then use the variable's context.
3334 2003-10-21 Paul D. Smith <psmith@gnu.org>
3336 * main.c (log_working_directory): Add newlines to printf()s.
3338 * README.cvs: Add a note to ignore warnings during autoreconf.
3340 * maintMakefile (po_repo): Set a new URL for PO file updates.
3341 (get-config/config.guess get-config/config.sub): Get these files
3342 from the Savannah config project instead of ftp.gnu.org.
3344 2003-10-05 Paul Eggert <eggert@twinsun.com>
3346 * main.c (main): Avoid potential subscript error if environ has
3349 2003-08-22 Paul D. Smith <psmith@gnu.org>
3351 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3352 systems which don't yet implement the C89 standard :-/.
3354 2003-07-18 Paul D. Smith <psmith@gnu.org>
3356 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3357 [WINDOWS32]: Initialize hash.
3359 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3361 * dir.c (read_dirstream): Provide a workaround for broken versions of
3362 the MinGW dirent structure.
3364 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3366 * w32/include/dirent.h: Add __MINGW32__ filter.
3368 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3370 * make.h: Add global declaration of *make_host.
3371 * main.c (print_usage): Remove local declaration of *make_host.
3372 (print_version): Display "This program built for ..." after Copyright
3375 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3377 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3378 execution of "makeinfo --html make.texi".
3380 2003-04-30 Paul D. Smith <psmith@gnu.org>
3382 * build.template: Make some changes to maybe allow this script to
3383 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3385 * README.OS2.template: New file for OS/2 support. Original
3386 contributed by Andreas Buening.
3387 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3390 2003-04-19 Paul D. Smith <psmith@gnu.org>
3392 Fix bug #1405: allow a target to match multiple pattern-specific
3395 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3396 variable.c, where they've always belonged.
3397 * rule.h: Move the prototypes and struct pattern_var as well.
3398 * variable.c (initialize_file_variables): Invoke
3399 lookup_pattern_var() in a loop, until no more matches are found.
3400 If a match is found, create a new variable set for the target's
3401 pattern variables. Then merge the contents of each matching
3402 pattern variable set into the target's pattern variable set.
3403 (lookup_pattern_var): Change this function to be usable
3404 in a loop. It takes a starting position: if NULL, start at the
3405 beginning; if non-NULL, start with the pattern variable after that
3406 position, and return the next matching pattern.
3407 (create_pattern_var): Create a unique instance of
3408 pattern-specific variables for every definition in the makefile.
3409 Don't combine the same pattern together. This allows us to
3410 process the variable handling properly even when the same pattern
3411 is used multiple times.
3412 (parse_variable_definition): New function: break out the parsing
3413 of a variable definition line from try_variable_definition.
3414 (try_variable_definition): Call parse_variable_definition to
3416 (print_variable_data_base): Print out pattern-specific variables.
3417 * variable.h (struct variable): Remember when a variable is
3418 conditional. Also remember its flavor.
3419 (struct pattern_var): Instead of keeping a variable set, we just
3420 keep a single variable for each pattern.
3421 * read.c (record_target_var): Each pattern variable contains only a
3422 single variable, not a set, so create it properly.
3423 * doc/make.texi (Pattern-specific): Document the new behavior.
3425 2003-04-17 Paul D. Smith <psmith@gnu.org>
3427 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3428 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3429 file/directory naming rules for VMS so I can't tell whether this
3432 2003-04-09 Paul D. Smith <psmith@gnu.org>
3434 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3435 DOS-style pathnames: backslash separators and drive specifiers.
3437 2003-03-28 Paul D. Smith <psmith@gnu.org>
3439 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3440 the intermediate flag on all targets. Fixes bug #2515.
3442 2003-03-24 Paul D. Smith <psmith@gnu.org>
3444 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3445 Upgrade to autoconf 2.57 and automake 1.7.3.
3447 * job.c: More OS/2 changes from Andreas Buening.
3449 * file.c (print_file): Fix variable initialization.
3452 * remake.c (notice_finished_file):
3454 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3455 some calls (like readdir()) return NULL in valid situations
3456 without resetting errno. Fixes bug #2846.
3458 2003-02-25 Paul D. Smith <psmith@gnu.org>
3460 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3462 * job.c (_is_unixy_shell) [OS/2]: New function.
3463 Set default shell to /bin/sh.
3464 (reap_children): Close the job_rfd pipe here since we don't use a
3466 (set_child_handler_action_flags): define this to empty on OS/2.
3467 (start_job_command): Close the jobserver pipe and use
3468 child_execute_job() instead of fork/exec.
3469 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3470 rather than exec'ing, then reconfigure stdin/stdout.
3471 (exec_command): Rewrite to use spawn instead of exec. Return the
3474 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3475 in DOS. Handle the TEMP environment variable as in DOS. Don't
3476 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3477 use -j in DOS mode. Use child_execute_job() instead of
3480 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3483 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3484 prototypes that return values.
3486 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3488 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3489 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3491 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3494 2003-02-24 Paul D. Smith <psmith@gnu.org>
3496 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3497 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3498 (child_execute_job) [VMS]: Handle error status properly.
3499 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3501 * function.c (func_shell): Use EINTRLOOP() while reading from the
3502 subshell pipe (Fixes bug #2502).
3503 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3505 * main.c (main): Ditto.
3507 2003-01-30 Paul D. Smith <psmith@gnu.org>
3509 * read.c (eval): eval() was not fully reentrant, because the
3510 collapsed buffer was static. Change it to be an automatic
3511 variable so that eval() can be invoked recursively.
3513 (eval): Apply patch # 1022: fix memory reference error on long
3514 target-specific variable lines.
3515 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3517 * function.c (check_numeric): Combine the is_numeric() function
3518 into this function, since it's only called from one place.
3519 Constify this function. Have it print the incorrect string in the
3520 error message. Fixes bug #2407.
3521 (strip_whitespace): Constify.
3522 (func_if): Constify.
3523 * expand.c (expand_argument): Constify.
3525 2003-01-29 Paul D. Smith <psmith@gnu.org>
3527 Fix bug # 2169, also reported by other people on various systems.
3529 * make.h: Some systems, such as Solaris and PTX, do not fully
3530 implement POSIX-compliant SA_RESTART functionality; important
3531 system calls like stat() and readdir() can still fail with EINTR
3532 even if SA_RESTART has been set on the signal handler. So,
3533 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3534 EINTR for system calls which return -1 or 0 (NULL), respectively,
3536 Also, remove the old atomic_stat()/atomic_readdir() and
3537 HAVE_BROKEN_RESTART handling.
3539 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3541 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3542 * remake.c (touch_file): Ditto.
3544 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3545 * read.c (construct_include_path): Ditto.
3546 * remake.c (name_mtime): Ditto.
3547 * vpath.c (selective_vpath_search): Ditto.
3548 * dir.c (find_directory): Ditto.
3549 (local_stat): Ditto.
3550 (find_directory): Use ENULLLOOP() to wrap opendir().
3551 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3553 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3554 atomic_readdir() handling.
3556 2003-01-22 Paul D. Smith <psmith@gnu.org>
3558 * function.c (func_call): Fix Bug #1744. If we're inside a
3559 recursive invocation of $(call ...), mask any of the outer
3560 invocation's arguments that aren't used by this one, so that this
3561 invocation doesn't "inherit" them accidentally.
3563 2002-12-05 Paul D. Smith <psmith@gnu.org>
3565 * function.c (subst_expand): Valery Khamenia reported a
3566 pathological performance hit when doing substitutions on very
3567 large values with lots of words: turns out we were invoking
3568 strlen() a ridiculous number of times. Instead of having each
3569 call to sindex() call strlen() again, keep track of how much of
3570 the text we've seen and pass the length to sindex().
3572 2002-11-19 Paul D. Smith <psmith@gnu.org>
3574 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3577 2002-11-16 Paul D. Smith <psmith@gnu.org>
3579 * NMakefile.template (OBJS): Add hash.c object file.
3580 * SMakefile.template (srcs): Ditto.
3581 * Makefile.ami (objs): Ditto.
3582 * build_w32.bat: Ditto.
3584 * Makefile.DOS.template: Remove extra dependencies.
3586 2002-10-25 Paul D. Smith <psmith@gnu.org>
3588 * expand.c (install_variable_buffer): New function. Install a new
3589 variable_buffer context and return the previous one.
3590 (restore_variable_buffer): New function. Free the current
3591 variable_buffer context and put a previously saved one back.
3592 * variable.h: Prototypes for {install,restore}_variable_buffer.
3593 * function.c (func_eval): Push a new variable_buffer context
3594 before we eval, then restore the old one when we're done.
3597 * read.c (install_conditionals): New function. Install a new
3598 conditional context and return the previous one.
3599 (restore_conditionals): New function. Free the current
3600 conditional context and put a previously saved one back.
3601 (eval): Use the {install,restore}_conditionals for "include"
3603 (eval_buffer): Use {install,restore}_conditionals to preserve the
3604 present conditional state before we evaluate the buffer.
3607 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3609 (Recursion): Add a variable index entry for CURDIR.
3611 * README.cvs: Update to appropriate versions.
3612 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3613 don't need to copy loadavg.c: automake is smart enough to create
3614 it for me. Still have a bug in automake related to ansi2knr tho.
3616 2002-10-14 Paul D. Smith <psmith@gnu.org>
3618 * remake.c (notice_finished_file): Only touch targets if they have
3619 at least one command (as per POSIX). Resolve Bug #1418.
3621 * *.c: Convert to using ANSI C-style function definitions.
3622 * Makefile.am: Enable the ansi2knr feature of automake.
3623 * configure.in: ditto.
3625 2002-10-13 Paul D. Smith <psmith@gnu.org>
3627 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3628 for automatic variable values like $^, etc. In the case of very
3629 large lists of prerequisites this causes problems. Instead reuse
3630 a static buffer (resizeable) for each variable.
3632 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3633 target-specific variable definitions. Check for it and set an
3635 (record_target_var): Set the export field to v_export if the
3636 "exported" flag is set.
3637 * doc/make.texi (Target-specific): Document the ability to use
3640 * doc/make.texi: Change the name of the section on automatic
3641 variables from "Automatic" to "Automatic Variables". Added text
3642 clarifying the scope of automatic variables.
3644 2002-10-04 Paul D. Smith <psmith@gnu.org>
3646 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3648 (record_files): Ditto.
3650 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3651 the search for the '=' to only within the enclosing parens.
3653 2002-10-03 Paul D. Smith <psmith@gnu.org>
3655 Version 3.80 released.
3657 * dir.c: Change hash functions to use K&R function definition style.
3658 * function.c: Ditto.
3660 * variable.c: Ditto.
3662 Update to automake 1.7.
3664 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3665 (pdf): Remove this target as automake now provides one.
3667 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3669 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3671 * makefile.com: Updates for GNU make 3.80.
3672 * makefile.vms: Ditto.
3674 2002-09-23 Paul D. Smith <psmith@gnu.org>
3676 * read.c (enum make_word_type): Remove w_comment.
3677 (get_next_mword): Don't treat comment characters as special; where
3678 this function is used we will never see a comment (it's stripped
3679 before we get here) and treating comments specially means that
3680 targets like "foo\#bar" aren't handled properly.
3682 2002-09-18 Paul D. Smith <psmith@gnu.org>
3684 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3686 * read.c (eval): Expansion of arguments to export/unexport was
3687 ignoring all arguments after the first one. Change the algorithm
3688 to expand the whole line once, then parse the results.
3690 2002-09-17 Paul D. Smith <psmith@gnu.org>
3692 Fix Bug #940 (plus another bug I found while looking at this):
3694 * read.c (record_target_var): enter_file() will add a new entry if
3695 it's a double-colon target: we don't want to do that in this
3696 situation. Invoke lookup_file() and only enter_file() if it does
3697 not already exist. If the file we get back is a double-colon then
3698 add this variable to the "root" double-colon target.
3700 * variable.c (initialize_file_variables): If this file is a
3701 double-colon target but is not the "root" target, then initialize
3702 the root and make the root's variable list the parent of our
3705 2002-09-13 Paul D. Smith <psmith@gnu.org>
3707 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3709 * hash.c (round_up_2): Get rid of a warning.
3711 2002-09-12 Paul D. Smith <psmith@gnu.org>
3713 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3714 so it doesn't complain about getloadavg.c.
3716 * commands.c (set_file_variables): Make sure we always alloca() at
3717 least 1 character for the value of $? (for '\0').
3719 2002-09-11 Paul D. Smith <psmith@gnu.org>
3721 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3722 macro to use RESULT instead of the incorrect _RESULT_.
3724 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3725 and atomic_readdir(). We need to #include dirent.h to get this to
3727 * misc.c (atomic_readdir): Fix typos.
3729 2002-09-10 Paul D. Smith <psmith@gnu.org>
3731 * read.c (eval): Expand variable lists given to export and
3732 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3733 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3735 * doc/make.texi (Variables/Recursion): Document this.
3736 (Conditional Syntax): And here.
3738 2002-09-09 Paul D. Smith <psmith@gnu.org>
3740 * configure.in: Check for memmove().
3742 2002-09-07 Paul D. Smith <psmith@gnu.org>
3744 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3745 Michael Sterrett <msterret@coat.com> reports that while it has
3746 SA_RESTART, it does not work properly.
3748 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3749 that invokes stat() and loops to do it again if it returns EINTR.
3750 (atomic_readdir): Ditto, with readdir().
3752 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3753 and readdir() to atomic_stat() and atomic_readdir().
3755 2002-09-04 Paul D. Smith <psmith@gnu.org>
3757 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3758 reports that GNU make sometimes doesn't recognize that targets can
3759 be made, when directories can be created as prerequisites. He
3760 reports that changing the order of predicates in the DEP->changed
3761 flag test so that lookup_file() is always performed, solves this
3764 2002-08-08 Paul D. Smith <psmith@gnu.org>
3766 * configure.in: Require a newer version of gettext.
3768 * misc.c (perror_with_name): Translate the format string (for
3769 right-to-left language support).
3770 (pfatal_with_name): Ditto.
3772 * main.c: Create a static array of strings to store the usage
3773 text. This is done to facilitate translations.
3774 (struct command_switch): Remove argdesc and description fields.
3775 (switches): Remove values for obsolete fields.
3776 (print_usage): Print each element of the usage array.
3778 * hash.c: Change function definitions to be K&R style.
3780 2002-08-02 Paul D. Smith <psmith@gnu.org>
3782 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3783 this one because it's too hard to get right. We'll look at it for
3785 * main.c (main): Don't create the .TARGETS variable.
3786 * variable.c (handle_special_var): Don't handle .TARGETS.
3788 2002-08-01 Paul D. Smith <psmith@gnu.org>
3790 * main.c (switches): Add a new option, -B (--always-make). If
3791 specified, make will rebuild all targets that it encounters even
3792 if they don't appear to be out of date.
3793 (always_make_flag): New flag.
3794 * make.h: Extern always_make_flag.
3795 * remake.c (update_file_1): Check always_make_flag; if it's set we
3796 will always rebuild any target we can, even if none of its
3797 prerequisites are newer.
3800 * doc/make.texi (Shell Function): Make it clear that make
3801 variables marked as "export" are not passed to instances of the
3804 Add new introspection variable .VARIABLES and .TARGETS.
3806 * variable.c (handle_special_var): New function. If the variable
3807 reference passed in is "special" (.VARIABLES or .TARGETS),
3808 calculate the new value if necessary. .VARIABLES is handled here:
3809 walk through the hash of defined variables and construct a value
3810 which is a list of the names. .TARGETS is handled by
3811 build_target_list().
3812 (lookup_variable): Invoke handle_special_var().
3813 * file.c (build_target_list): Walk through the hask of known files
3814 and construct a list of the names of all the ones marked as
3816 * main.c (main): Initialize them to empty (and as simple variables).
3817 * doc/make.texi (Special Variables): Document them.
3818 * NEWS: Mention them.
3820 * variable.h (struct variable): Add a new flag "exportable" which
3821 is true if the variable name is valid for export.
3822 * variable.c (define_variable_in_set): Set "exportable" when a new
3823 variable is defined.
3824 (target_environment): Use the "exportable" flag instead of
3825 re-checking the name here... an efficiency improvement.
3827 2002-07-31 Paul D. Smith <psmith@gnu.org>
3829 * config.h-vms.template: Updates to build on VMS. Thanks to
3830 Brian_Benning@aksteel.com for helping verify the build.
3831 * makefile.com: Build the new hash.c file.
3832 * hash.h: Use strcpmi(), not stricmp(), in the
3833 HAVE_CASE_INSENSITIVE_FS case.
3835 2002-07-30 Paul D. Smith <psmith@gnu.org>
3837 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3838 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3839 Reported by <Brian_Benning@aksteel.com>.
3841 2002-07-10 Paul D. Smith <psmith@gnu.org>
3843 * variable.c (pop_variable_scope): Remove variable made unused by
3844 new hash infrastructure.
3845 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3846 comparisons as well as name comparisons.
3847 * variable.h: Add a prototype for new hash_init_function_table().
3848 * file.c (lookup_file): Remove variables made unused by new hash
3850 * dir.c (directory_contents_hash_2): Missing return of hash value.
3851 (dir_contents_file_exists_p): Remove variables made unused by new
3852 hash infrastructure.
3855 Installed Greg McGary's integration of the hash functions from the
3856 GNU id-utils package:
3858 2002-07-10 Greg McGary <greg@mcgary.org>
3860 * scripts/functions/filter-out: Add literals to to the
3861 pattern space in order to add complexity, and trigger
3862 use of an internal hash table. Fix documentation strings.
3863 * scripts/targets/INTERMEDIATE: Reverse order of files
3864 passed to expected `rm' command.
3866 2002-07-10 Greg McGary <greg@mcgary.org>

3958 2002-07-10 Paul D. Smith <psmith@gnu.org>
3960 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3961 prerequisite list. A real SysV make will expand the entire
3962 prerequisites list _twice_: we don't do that as it's a big
3963 backward-compatibility problem. We only replace those specific
3966 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3967 references left in the list of prerequisites. Check for .POSIX as
3968 we record targets, so we can disable non-POSIX behavior while
3969 reading makefiles as well as running them.
3970 (eval): Check the prerequisite list to see if we have anything
3971 that looks like a SysV prerequisite variable reference.
3973 2002-07-09 Paul D. Smith <psmith@gnu.org>
3975 * doc/make.texi (Prerequisite Types): Add a new section describing
3976 order-only prerequisites.
3978 * read.c (uniquize_deps): If we have the same file as both a
3979 normal and order-only prereq, get rid of the order-only prereq,
3980 since the normal one supersedes it.
3982 2002-07-08 Paul D. Smith <psmith@gnu.org>
3984 * AUTHORS: Added Greg McGary to the AUTHORS file.
3985 * NEWS: Blurbed order-only prerequisites.
3986 * file.c (print_file): Show order-only deps properly when printing
3989 * maintMakefile: Add "update" targets for wget'ing the latest
3990 versions of various external files. Taken from Makefile.maint in
3993 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3994 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3996 2002-07-07 Paul D. Smith <psmith@gnu.org>
3998 * po/*.po: Remove. We'll use wget to retrieve them at release
4001 * variable.c (do_variable_definition) [W32]: On W32 using cmd
4002 rather than a shell you get an exception. Make sure we look up
4003 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
4005 * remake.c (notice_finished_file): Fix handling of -t flag.
4006 Patch provided by Henning Makholm <henning@makholm.net>.
4008 * implicit.c (pattern_search): Some systems apparently run short
4009 of stack space, and using alloca() in this function caused an
4010 overrun. I modified it to use xmalloc() on the two variables
4011 which seemed like they might get large. Fixes Bug #476.
4013 * main.c (print_version): Update copyright notice to conform with
4015 (print_usage): Update help output.
4017 * function.c (func_eval): Create a new make function, $(eval
4018 ...). Expand the arguments, put them into a buffer, then invoke
4019 eval_buffer() on the resulting string.
4020 (func_quote): Create a new function, $(quote VARNAME). Inserts
4021 the value of the variable VARNAME without expanding it any
4024 * read.c (struct ebuffer): Change the linebuffer structure to an
4025 "eval buffer", which can be either a file or a buffer.
4026 (eval_makefile): Move the code in the old read_makefile() which
4027 located a makefile into here: create a struct ebuffer with that
4028 information. Have it invoke the new function eval() with that
4030 (eval_buffer): Create a new function that creates a struct ebuffer
4031 that holds a string buffer instead of a file. Have it invoke
4032 eval() with that ebuffer.
4033 (eval): New function that contains the guts of the old
4034 read_makefile() function: this function parses makefiles. Obtains
4035 data to parse from the provided ebuffer. Some modifications to
4036 make the flow of the function cleaner and clearer. Still could
4037 use some work here...
4038 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
4039 contents of the define/endef variable from the ebuffer.
4040 (readstring): Read the next line from a string-style ebuffer.
4041 (readline): Read the next line from an ebuffer. If it's a string
4042 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
4045 * dep.h (eval_buffer): Prototype eval_buffer();
4047 * variable.c (do_variable_definition): Make sure that all
4048 non-target-specific variables are registered in the global set.
4049 If we're invoked from an $(eval ...) we might be inside a $(call
4050 ...) or other function which has pushed a variable scope; we still
4051 want to define our variables from evaluated makefile code in the
4054 2002-07-03 Greg McGary <greg@mcgary.org>
4056 * dep.h (struct dep) [ignore_mtime]: New member.
4057 [changed]: convert to a bitfield.
4058 * implicit.c (pattern_search): Zero ignore_mtime.
4059 * main.c (main, handle_non_switch_argument): Likewise.
4060 * rule.c (convert_suffix_rule): Likewise.
4061 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
4062 (read_makefile): Parse '|' in prerequisite list.
4063 (uniquize_deps): Consider ignore_mtime when comparing deps.
4064 * remake.c (update_file_1, check_dep): Don't force remake for
4065 dependencies that have d->ignore_mtime.
4066 * commands.c (FILE_LIST_SEPARATOR): New constant.
4067 (set_file_variables): Don't include a
4068 prerequisite in $+, $^ or $? if d->ignore_mtime.
4071 2002-06-18 Paul D. Smith <psmith@gnu.org>
4073 * make.texinfo: Updates for next revision. New date/rev/etc.
4074 Recreate all Info menus. Change license on the manual to the GNU
4075 Free Documentation License. A number of typos.
4076 (Variables Simplify): Don't use "-" before it's defined.
4077 (Automatic Prerequisites): Rewrite the target example to work
4078 properly if the compile fails. Remove incorrect comments about
4079 how "set -e" behaves.
4080 (Text Functions): Move the "word", "wordlist", "words", and
4081 "firstword" functions here, from "File Name Functions".
4082 * make-stds.texi: Update from latest GNU version.
4083 * fdl.texi: (created) Import the latest GNU version.
4085 2002-06-06 Paul D. Smith <psmith@gnu.org>
4087 * variable.c (do_variable_definition): New function: extract the
4088 part of try_variable_definition() that actually sets the value
4089 into a separate function.
4090 (try_variable_definition): Call do_variable_definition() after
4091 parsing the variable definition string.
4092 (define_variable_in_set): Make the name argument const.
4094 * variable.h (enum variable_flavor): Make public.
4095 (do_variable_definition): Create prototype.
4097 * read.c (read_all_makefiles): Create a new built-in variable,
4099 (read_makefile): Add each makefile read in to this variable value.
4101 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4103 * Makefile.DOS.template: Tweak according to changes in the
4104 distribution. Add back the dependencies of *.o files.
4106 * configh.dos.template: Synchronize with config.h.in.
4108 2002-05-09 Paul D. Smith <psmith@gnu.org>
4110 * file.c (file_timestamp_now): Use K&R function declaration.
4112 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4113 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4114 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4115 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4116 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4117 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4118 nlist.n_name is a pointer rather than an array.
4120 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4121 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4122 * configure.in: Use it instead of the old version.
4124 * main.c (main): Prefer setvbuf() to setlinebuf().
4126 2002-05-08 Paul D. Smith <psmith@gnu.org>
4128 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4129 (loadavg_LDADD): Ditto.
4131 2002-04-29 Paul D. Smith <psmith@gnu.org>
4133 * expand.c (recursively_expand_for_file): Rename
4134 recursively_expand() to recursively_expand_for_file() and provide
4135 an extra argument, struct file. If the argument is provided, set
4136 the variable scope to that of the file before expanding.
4137 * variable.h (recursively_expand): Make this a macro that invokes
4138 recursively_expand_for_file() with a NULL file pointer.
4139 * variable.c (target_environment): Call the renamed function and
4140 provide the current file context.
4141 Fixes Debian bug #144306.
4143 2002-04-28 Paul D. Smith <psmith@gnu.org>
4145 Allow $(call ...) user-defined variables to be self-referencing
4146 without throwing an error. Allows implementation of transitive
4147 closures, among other possibly useful things.
4148 Requested by: Philip Guenther <guenther@sendmail.com>
4150 * variable.h (struct variable): Add a new field: exp_count, and
4151 new macros to hold its size and maximum value.
4152 (warn_undefined): Make this a macro.
4153 * variable.c (define_variable_in_set): Initialize it.
4154 * expand.c (recursively_expand): If we detect recursive expansion
4155 of a variable, check the exp_count field. If it's greater than 0
4156 allow the recursion and decrement the count.
4157 (warn_undefined): Remove this (now a macro in variable.h).
4158 * function.c (func_call): Before we expand the user-defined
4159 function, modify its exp_count field to contain the maximum
4160 number of recursive calls we'll allow. After the call, reset it
4163 2002-04-21 Paul D. Smith <psmith@gnu.org>
4165 Modified to use latest autoconf (2.53), automake (1.6.1), and
4166 gettext (0.11.1). We're using gettext's new "external" support,
4167 to avoid including libintl source with GNU make.
4169 * README.cvs: New file. Explain how to build GNU make from CVS.
4171 * configure.in: Modify checking for the system glob library.
4172 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4173 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4174 etc. will manage it correctly). Set an automake conditional
4175 USE_LOCAL_GLOB to decide whether to compile the glob library.
4177 * getloadavg.c (main): Include make.h in the "TEST" program to
4180 * Makefile.am: Remove special rules for loadavg. Replace them
4181 with Automake capabilities for building extra programs.
4183 * signame.c: This file does nothing if the system provide
4184 strsignal(). If not, it implements strsignal(). If the system
4185 doesn't define sys_siglist, then we make our own; otherwise we use
4187 * signame.h: Removed.
4189 * main.c (main): No need to invoke signame_init(). Update copyright.
4191 * ABOUT-NLS: Removed.
4192 * gettext.c: Removed.
4193 * gettext.h: Get a simplified copy from the gettext package.
4195 * i18n/*.po: Moved to po/.
4198 * config/*: Created. Contains package configuration helper files.
4199 * config.guess, config.sub: Moved to config directory.
4201 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4202 Rework to use new-style autoconf features. Use the "external"
4203 mode for gettext. Make the build.sh config file conditional on
4204 whether build.sh.in exists, to avoid autoconf errors.
4205 * acinclude.m4: Removed almost all macros as being obsolete.
4206 Rewrote remaining macros to use AC_DEFINE.
4207 * acconfig.h: Removed.
4209 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4210 conditional to handle customs support. Remove special handling
4213 2002-04-20 Paul D. Smith <psmith@gnu.org>
4215 * function.c (func_call): Don't mark the argument variables $1,
4216 etc. as recursive. They've already been fully expanded so
4217 there's no need to do it again, and doing so strips escaped $'s.
4218 Reported by Sebastian Glita <glseba@yahoo.com>.
4220 * remake.c (notice_finished_file): Walk through double-colon
4221 entries via the prev field, not the next field!
4222 Reported by Greg McGary <greg@mcgary.org>.
4224 * main.c (main): If the user specifies -q and asks for a specific
4225 target which is a makefile, we got an assert. In that case it
4226 turns out we should continue normally instead.
4228 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4230 * i18n/he.po: Installed a new translation.
4232 2002-01-07 Paul D. Smith <psmith@gnu.org>
4234 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4236 2001-12-04 Paul D. Smith <psmith@gnu.org>
4238 * i18n/ja.po: Installed an updated translation.
4240 2001-09-06 Paul Eggert <eggert@twinsun.com>
4242 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4243 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4245 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4247 (main): Get rid of any avoidable limit on stack size.
4249 2001-09-04 Paul D. Smith <psmith@gnu.org>
4251 * i18n/da.po: Installed an updated translation.
4253 2001-08-03 Paul D. Smith <psmith@gnu.org>
4255 * i18n/fr.po: Installed an updated translation.
4256 Resolves Debian bug #106720.
4258 2001-06-13 Paul D. Smith <psmith@gnu.org>
4260 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4263 2001-06-11 Paul D. Smith <psmith@gnu.org>
4265 * i18n/ko.po: Installed a new translation.
4267 2001-05-06 Paul D. Smith <psmith@gnu.org>
4269 Modify the EINTR handling.
4271 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4272 the way in which we manage the file descriptor/signal handler race
4273 trap to be more efficient.
4275 2001-05-06 Paul Eggert <eggert@twinsun.com>
4277 Restart almost all system calls that are interrupted, instead
4278 of worrying about EINTR. The lone exception is the read() for
4281 * configure.in (HAVE_SA_RESTART): New macro.
4282 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4283 * main.c (main): Use SA_RESTART instead of the old,
4284 nonstandard SA_INTERRUPT.
4286 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4287 * main.c (bsd_signal): New function or macro,
4288 if the implementation doesn't supply it.
4289 (The bsd_signal function will be in POSIX 1003.1-200x.)
4290 (HANDLESIG): Remove.
4291 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4293 * make.h (EINTR_SET): Remove.
4294 (SA_RESTART): New macro.
4296 * arscan.c (ar_member_touch): Don't worry about EINTR.
4297 * function.c (func_shell): Likewise.
4298 * job.c (reap_children, free_child, new_job): Likewise.
4299 * main.c (main): Likewise.
4300 * remake.c (touch_file, name_mtime): Likewise.
4302 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4303 if fstat failed with errno!=EINTR, the error was ignored.
4305 * job.c (set_child_handler_action_flags): New function.
4306 (new_job): Use it to temporarily clear the SIGCHLD action flags
4307 while reading the token.
4309 2001-05-02 Paul D. Smith <psmith@gnu.org>
4311 * job.c (start_job_command): Don't add define/endef per-line flags
4312 to the top-level flags setting.
4314 2001-04-03 Paul D. Smith <psmith@gnu.org>
4316 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4317 bit on error, so check for odd return values, not non-0 return
4319 (VMS_get_member_info): Calculate the timezone differences correctly.
4320 Reported by John Fowler <jfowler@nyx.net>.
4323 2001-03-14 Paul D. Smith <psmith@gnu.org>
4325 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4326 value before invoking define_variable().
4327 Reported by John Fowler <jfowler@nyx.net>.
4329 2001-02-07 Paul D. Smith <psmith@gnu.org>
4331 * read.c (record_target_var): If we reset the variable due to a
4332 command-line variable setting overriding it, turn off the "append"
4335 2001-01-17 Paul D. Smith <psmith@gnu.org>
4337 * variable.c (lookup_variable) [VMS]: When getting values from the
4338 environment, allocate enough space for the _value_ plus escapes,
4339 not enough space for the name plus escapes :-/.
4340 Reported by John Fowler <jfowler@nyx.net>.
4342 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4343 warnings that make generates, so it doesn't look like an error.
4344 Reported by Karl Berry <karl@gnu.org>.
4347 Fix for PR/2020: Rework appended target-specific variables. I'm
4348 fairly confident this algorithm is finally correct.
4350 * expand.c (allocated_variable_append): Rewrite. Instead of
4351 expanding each appended variable then adding all the expanded
4352 strings together, we append all the unexpanded values going up
4353 through the variable set contexts, then expand the final result.
4354 This behaves just like non-target-specific appended variable
4355 values, while the old way didn't in various corner cases.
4356 (variable_append): New function: recursively append the unexpanded
4357 value of a variable, walking from the outermost variable scope to
4359 * variable.c (lookup_variable): Remove the code that looked up the
4360 variable set list if the found variable was "append". We don't
4362 (lookup_variable_in_set): Make this non-static so we can use it
4364 (try_variable_definition): Use lookup_variable_in_set() rather
4365 than faking out current_variable_set_list by hand (cleanup).
4366 * variable.h: Add a prototype for the now non-static
4367 lookup_variable_in_set().
4369 2000-11-17 Paul D. Smith <psmith@gnu.org>
4371 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4372 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4373 before throwing a fit.
4375 2000-11-17 Paul D. Smith <psmith@gnu.org>
4377 * read.c (readline): CRLF calculations had a hole, if you hit the
4378 buffer grow scenario just right. Reworked the algorithm to avoid
4379 the need for len or lastlen at all. Problem description with
4380 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4382 2000-10-24 Paul D. Smith <psmith@gnu.org>
4384 * gettext.c (SWAP): Declare this with the prototype, otherwise
4385 some systems don't work (non-32-bit? Reported for Cray T3E).
4386 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4388 2000-10-05 Paul D. Smith <psmith@gnu.org>
4390 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4391 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4393 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4395 2000-09-22 Paul D. Smith <psmith@gnu.org>
4397 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4398 parts of the real gettext.h here, and we expect to really include
4399 the real gettext.h later. If we keep this #define, it's ignored.
4401 2000-09-21 Paul D. Smith <psmith@gnu.org>
4403 * main.c (log_working_directory): Rework the text to use complete
4404 sentences, to make life simpler for the translators.
4406 2000-08-29 Paul D. Smith <psmith@gnu.org>
4408 * file.c (remove_intermediates): Print a debug message before we
4409 remove intermediate files, so the user (if she uses -d) knows
4412 2000-08-21 Paul D. Smith <psmith@gnu.org>
4414 * variable.c (try_variable_definition): Change how we handle
4415 target-specific append variable defns: instead of just setting the
4416 value, expand it as an append _but_ only within the current
4417 target's context. Otherwise we lose all but the last value if the
4418 variable is appended more than once within the current target
4419 context. Fixes PR/1831.
4421 2000-08-16 Paul D. Smith <psmith@gnu.org>
4423 * function.c (func_shell): Nul-terminate the buffer before
4424 printing an exec error message (just in case it's not!).
4425 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4427 2000-07-25 Paul D. Smith <psmith@gnu.org>
4429 * job.c (construct_command_argv_internal): Add "~" to the list of
4430 sh_chars[] which disallow optimizing out the shell call.
4432 2000-07-23 Paul Eggert <eggert@twinsun.com>
4434 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4435 supersedes --disable-nsec-timestamps.
4436 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4437 * README: Remove --disable-nsec-timestamps.
4439 * filedef.h (struct file.low_resolution_time): New member.
4440 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4441 * remake.c (update_file_1):
4442 Avoid spurious rebuilds due to low resolution time stamps,
4443 generalizing the earlier code that applied only to archive members.
4444 (f_mtime): Archive members always have low resolution time stamps.
4446 * configure.in: Remove --disable-nsec-timestamps, as this has
4447 been superseded by .LOW_RESOLUTION_TIME.
4449 2000-07-23 Paul Eggert <eggert@twinsun.com>
4451 * configure.in (enable_nsec_timestamps): Renamed from
4452 make_cv_nsec_timestamps, since enable/disable options
4453 shouldn't be cached.
4455 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4456 and Paul Eggert <eggert@twinsun.com>
4458 * file.c (file_timestamp_now):
4459 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4460 so that clock_gettime is not linked unless needed.
4462 * filedef.h (FILE_TIMESTAMP_HI_RES):
4463 Remove definition; "configure" now does this.
4465 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4466 to before high resolution file timestamp check,
4467 since that check now uses uintmax_t.
4468 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4469 high resolution file timestamps.
4470 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4471 so that we don't link in clock_gettime unnecessarily.
4473 2000-07-17 Paul D. Smith <psmith@gnu.org>
4475 * i18n/ja.po: New version of the translation file.
4477 2000-07-07 Paul D. Smith <psmith@gnu.org>
4479 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4480 the offset calculation.
4481 (name_mtime): Replace EINTR test with EINTR_SET macro.
4483 2000-07-07 Paul Eggert <eggert@twinsun.com>
4487 * remake.c (update_file_1):
4488 Avoid spurious rebuilds of archive members due to their
4489 timestamp resolution being only one second.
4490 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4491 the clock's resolution being lower than file timestamps'.
4492 When warning about future timestamps, report only the discrepancy,
4493 not the absolute value of the timestamp and the current time.
4495 * file.c (file_timestamp_now): New arg RESOLUTION.
4496 * filedef.h (file_timestamp_now): Likewise.
4497 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4499 2000-07-05 Paul D. Smith <psmith@gnu.org>
4501 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4502 to listp. Fixes PR/1793.
4504 2000-06-26 Paul Eggert <eggert@twinsun.com>
4506 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4508 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4510 * remake.c (f_mtime): Remove unused var memtime.
4512 2000-06-25 Martin Buchholz <martin@xemacs.org>
4514 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4515 Ran spell-check on make.texinfo.
4517 2000-06-23 Paul D. Smith <psmith@gnu.org>
4519 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4520 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4521 * make.h: Define these macros.
4523 * Version 3.79.1 released.
4525 * configure.in: Add a new option, --disable-nsec-timestamps, to
4526 avoid using sub-second timestamps on systems that support it. It
4527 can lead to problems, e.g. if your makefile relies on "cp -p".
4528 * README.template: Document the issue with "cp -p".
4530 * config.guess, config.sub: Updated.
