856 double-colons have a different meaning. Savannah bug #27497.
858 2009-09-27 Juan Manuel Guerrero <juan.guerrero@gmx.de>
860 * configh.dos.template: Remove unconditional definition of
861 SYS_SIGLIST_DECLARED.
862 Include <sys/version.h> because ports of GCC 4.3.0 and later no
863 longer include it, so macros like __DJGPP_MINOR__ are no longer
864 defined automatically.
866 * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
867 corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
868 instead of using the hardcoded ones.
869 (SUBDIRS): doc subdir added.
870 (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
871 (TEXI2HTML, TEXI2HTML_FLAGS): Removed. Use makeinfo --html to
872 create html formated docs. texi2html may not be ported to DOS.
873 (make.info, make.dvi, make.ps, make.html): Make targets depend on
875 (.texi.info, .texi, .texi.dvi): Now invoked recursively. Change
876 -I switch to look in ./ instead of ./doc.
877 (html): Target depend on html-recursive instead of make_1.html.
878 (make_1.html): Removed.
879 (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.

883 (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
884 (tags-recursive): Allow for more than one subdir in the build
886 (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
887 targets. Enter into doc/ to produce the targets.
888 (all-am): $(INFO_DEPS) replaced by info.
890 2009-09-26 Paul Smith <psmith@gnu.org>
892 * read.c (record_files): Use free_ns() to free struct nameseq.
895 * rule.c (freerule): Use free_dep_chain().
897 * read.c (record_files): Free FILENAMES chain for implicit rules.
898 (eval): Static pattern targets go into the string cache.
900 * function.c (string_glob): Free NAME in the nameseq chain.
902 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
904 * implicit.c (pattern_search): Terminate early if we haven't
905 found any rules to try (performance improvement).
907 2009-09-25 Boris Kolpackov <boris@codesynthesis.com>
909 * implicit.c (pattern_search): Merge three parallel arrays,
910 TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
911 of struct TRYRULE. In the old version the latter two arrays
912 had insufficient length.
914 2009-09-24 Paul Smith <psmith@gnu.org>
916 * implicit.c (pattern_search): Add back support for order-only
917 prerequisites for secondary expansion implicit rules, that were
918 accidentally dropped. If we find a "|", enable order-only mode
919 and set IGNORE_MTIME on all deps that are seen afterward.
920 (pattern_search): Fix memory leaks: for intermediate files where
921 we've already set the file variable and pattern variable sets, be
922 sure to either save or free them as appropriate.
924 2009-09-23 Paul Smith <psmith@gnu.org>
926 Rework the way secondary expansion is stored, for efficiency.
927 This changes secondary expansion so that ONLY WHEN we know we have
928 a possibility of needing secondary expansion, do we defer the
929 secondary expansion. This means more parsing the deps but we use
930 a lot less memory (due to the strcache). Also, this fixes
933 * read.c (eval): Don't parse the dep string here anymore.
934 (record_files): Take the dep argument as an unparsed string. If
935 secondary expansion is enabled AND the prereq string has a '$' in
936 it, then set NEED_2ND_EXPANSION and keep the entire string.
937 Otherwise, parse the dep string here to construct the dep list
938 with the names in the strcache.
940 * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
941 duplicate the name string (others are in the strcache).
943 * implicit.c: Remove struct idep and free_idep_chain(): unused.
944 (struct patdeps): New structure to store prereq information.
945 (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
946 which prerequisites need expansion, and expand only those.
948 * file.c (split_prereqs): Break parse_prereqs() into two parts: this
949 and enter_prereqs(). split_prereqs() takes a fully-expanded string
950 and splits it into a DEP list, handling order-only prereqs.
951 (enter_prereqs): This function enters a list of DEPs into the file
952 database. If there's a stem defined, expand any pattern chars.
953 (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
954 set. Use the above functions.
955 (snap_deps): Only perform second expansion on prereqs that need it,
956 as defined by the NEED_2ND_EXPANSION flag.
957 (print_prereqs): New function to print the prereqs
958 (print_file): Call print_prereqs() rather than print inline.
960 * hash.h (STRING_COMPARE): Take advantage of strcache() by
962 (STRING_N_COMPARE): Ditto.
963 (ISTRING_COMPARE): Ditto.
965 * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
966 (parse_file_seq): Return void*
967 * read.c (parse_file_seq): Return void*.
968 (eval): Invoke macroized version of parse_file_seq()
969 * default.c (set_default_suffixes): Ditto.
970 * file.c (split_prereqs): Ditto.
971 * function.c (string_glob): Ditto.
972 * main.c (main): Ditto.
973 * rule.c (install_pattern_rule): Ditto.
975 * filedef.h: Add split_prereqs(), enter_prereqs(), etc.
977 2009-09-16 Paul Smith <psmith@gnu.org>
979 * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
981 * dep.h: Create alloc_dep() / free_dep() macros.
983 * implicit.c (pattern_search): Take advantage of the new
984 parse_file_seq() to add the directory prefix to each prereq.
986 * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
987 all. Avoid reversing chains. Support adding prefixes.
988 * read.c (parse_file_seq): Rewrite to support globbing. Allow for
989 cached/non-cached results.
990 (eval): Remove multi_glob() & invoke new parse_file_seq().
991 * rule.c (install_pattern_rule): Ditto.
992 * main.c (main): Ditto.
993 * implicit.c (pattern_search): Ditto.
994 * function.c (string_glob): Ditto.
995 * file.c (parse_prereqs): Ditto.
996 * default.c (set_default_suffixes): Ditto.
998 * variable.c (parse_variable_definition): Don't run off the end of
999 the string if it ends in whitespace (found with valgrind).
1001 * commands.c (set_file_variables): Keep space for all targets in
1002 $? if -B is given (found with valgrind).
1004 2009-09-15 Paul Smith <psmith@gnu.org>
1006 * misc.c (concat): Make concat() variadic so it takes >3 arguments.
1007 (xcalloc): Add new function.
1008 * make.h: New declarations.
1010 * ar.c (ar_glob_match): New calling method for concat().
1011 * main.c (main): Ditto.

1019 * ar.c (ar_glob_match): Use xcalloc().
1020 * dir.c (file_impossible): Ditto.
1021 * file.c (enter_file): Ditto.
1022 * job.c (new_job): Ditto.
1023 * read.c (parse_file_seq): Ditto.
1024 * vmsfunctions.c (opendir): Ditto.

1044 Fixes Savannah bug #18963.
1046 2009-08-01 Paul Smith <psmith@gnu.org>
1048 * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
1049 etc. come on the command line. Fixes Savannah bug #27093.
1051 * expand.c (expand_argument): If the argument is large enough use
1052 xmalloc() instead of alloca(). Fixes Savannah bug #27143.
1054 * variable.c (do_variable_definition): Avoid using alloca() to
1055 hold values, which can be large. Fixes Savannah bug #23960.
1057 * job.c (new_job): Use memmove() instead of strcpy() since both
1058 pointers are in the same memory block. Fixes Savannah bug #27148.
1059 Patch by Petr Machata.
1061 2009-07-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1068 * configure.in: Move side-effects outside AC_CACHE_VAL arguments
1069 that set make_cv_sys_gnu_glob, so they are also correctly set
1070 when the cache has been populated before.
1072 2009-07-04 Eli Zaretskii <eliz@gnu.org>
1074 * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
1075 exist, as realpath(3) does where it's supported.
1077 2006-07-04 Eli Zaretskii <eliz@gnu.org>
1079 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
1080 (abspath): Support systems that define HAVE_DOS_PATHS (have
1081 drive letters in their file names). Use IS_PATHSEP instead of a
1082 literal '/' comparison. Fixes Savannah bug #26886.
1084 2009-06-14 Paul Smith <psmith@gnu.org>
1086 * remake.c (update_file_1): Remember the original file we marked
1087 as updating, so we can clear that flag again. If we find a target
1088 via vpath, FILE might change.
1089 (check_dep): Ditto. Fixes Savannah bug #13529.
1090 Patch by Reid Madsen <reid.madsen@tek.com>.
1092 2009-06-13 Paul Smith <psmith@gnu.org>
1094 * doc/make.texi (MAKEFILES Variable): Be explicit that files
1095 included by MAKEFILES cannot give default goals.
1096 * read.c (eval): If set_default is not set, pass the no-default-goal
1097 value when we read included makefiles. Fixes Savannah bug #13401.
1099 * ar.c (ar_name): Ensure that targets with empty parens aren't
1100 considered archive member references: archive members must have a
1101 non-empty "member" string. Fixes Savannah bug #18435.
1103 * function.c (string_glob): Rely on multi_glob() to determine
1104 whether files exist or not. Remove call to file_exists_p() which
1105 is not always correct. Fixes Savannah bug #21231.
1106 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
1107 then only files that really exist will be returned.
1108 * dep.h: Add new argument to multi_glob().
1109 * rule.c (install_pattern_rule): Ditto.
1110 * read.c (eval): Ditto.
1111 * main.c (main): Ditto.
1112 * implicit.c (pattern_search): Ditto.
1113 * file.c (parse_prereqs): Ditto.
1114 * default.c (set_default_suffixes): Ditto.
1116 2009-06-09 Paul Smith <psmith@gnu.org>
1118 * commands.c (set_file_variables): If always_make_flag is set,
1119 always add the prereq to $?. Fixes Savannah bug #17825.
1121 * remake.c (update_file_1): When rebuilding deps of FILE, also try
1122 to rebuild the deps of all the also_make targets for that file.
1123 Fixes Savannah bug #19108.
1125 * implicit.c (pattern_search): Undo test for is_target, added by
1126 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
1127 Rule Search Algorithm". Fixes Savannah bug #17752.
1129 * main.c (clean_jobserver): Clear the jobserver_fds options and
1130 set job_slots to the default when we clean up.
1131 (define_makeflags): Return the new MAKEFLAGS value.
1132 (main): Reset MAKEFLAGS in the environment when we re-exec.
1133 Fixes Savannah bug #18124.
1135 2009-06-08 Paul Smith <psmith@gnu.org>
1137 * read.c (eval): Collapse continuations post-semicolon on target-
1138 specific variables. Fixes Savannah bug #17521.
1140 2009-06-07 Paul Smith <psmith@gnu.org>
1142 * job.c (reap_children): For older systems without waitpid() (are
1143 there any of these left?) run wait(2) inside EINTRLOOP to handle
1144 EINTR errors. Fixes Savannah bug #16401.
1146 * (various): Debug message cleanup. Fixes Savannah bug #16469.
1148 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
1150 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
1151 not the end, to catch second expansion $(eval ...) defining new
1152 target/prereq relationships during snap_deps.
1153 Fixes Savannah bug #24622.
1155 * read.c (record_files): The second-expansion "f->updating" hack
1156 was not completely correct: if assumed that the target with
1157 commands always had prerequisites; if one didn't then the ordering
1158 was messed up. Fixed for now to use f->updating to decide whether
1159 to preserve the last element in the deps list... but this whole
1160 area of constructing and reversing the deps list is too confusing
1161 and needs to be reworked. Fixes Savannah bug #21198.
1163 2009-06-06 Paul Smith <psmith@gnu.org>
1165 * hash.c (hash_insert): Remove useless test for NULL.
1166 Fixes Savannah bug #21823.
1168 * make.h: Move SET_STACK_SIZE determination to make.h.
1169 * main.c (main): New global variable, STACK_LIMIT, holds the
1170 original stack limit when make was started.
1171 * job.c (start_job_command): Reset the stack limit, if we changed it.
1172 Fixes Savannah bug #22010.
1174 * remake.c (check_dep): Only set the target's state to not-started
1175 if it's not already running. Found this while testing -j10 builds
1176 of glibc: various targets were being rebuilt multiple times.
1177 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
1180 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
1181 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
1184 2009-06-04 Paul Smith <psmith@gnu.org>
1186 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
1188 * maintMakefile: Modify access of config and gnulib Savannah
1189 modules to use GIT instead of CVS.
1191 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
1192 Fixes Savannah bug #24655.
1194 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
1195 this can happen during some invocations of $(eval ...) for example.
1196 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
1198 2009-06-02 Paul Smith <psmith@gnu.org>
1200 * configure.in: Check for fileno()
1201 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
1202 for the makefile file so invocations of $(shell ...) don't inherit it.
1203 Fixes Savannah bug #24277.
1205 2009-06-01 Paul Smith <psmith@gnu.org>
1207 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
1208 expansion was handled incorrectly. Rework the default goal
1209 handling to save the variable only. Remove default_goal_file and
1211 * read.c (eval): Check default_goal_var, not default_goal_name.
1212 * read.c (record_target_var): Don't check default_goal_file here.
1214 2009-05-31 Paul Smith <psmith@gnu.org>
1216 * main.c (main): Expand the .DEFAULT_GOAL variable before using
1217 it, and if the multi_glob() returns nothing (say it expanded to
1218 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
1220 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
1221 $(and ..) to the reference. Fixes Savannah bug #25694.
1223 * make.1: Be clear that some recipes will be executed even with -n.
1224 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
1226 * doc/make.texi (Override Directive): Make more clear how
1227 overrides and appends interact.
1228 Elucidates part of Savannah bug #26207.
1230 * read.c (record_target_var): Don't reset the origin on
1231 target-specific variables; try_variable_definition() will handle
1232 this correctly. Fixes Savannah bug #26207.
1234 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
1235 Fixes Savannah bug #25712.
1237 * implicit.c (pattern_search): Keep a pointer to the beginning of
1238 the filename and save that instead of the constructed pointer.
1239 Fixes Savannah bug #26593.
1240 Patch by Mark Seaborn <mrs@mythic-beasts.com>
1242 2009-05-30 Paul Smith <psmith@gnu.org>
1244 * doc/make.texi (Multi-Line): Add a description of the new abilities
1245 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
1246 "command sequence" vs. "recipe" syntax.
1247 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
1248 after a define, to create variables with those flavors.
1250 2009-05-25 Paul Smith <psmith@gnu.org>
1252 Reworked the parser for variable assignments to allow multiple
1253 modifiers, and in any order. Also allows variable and
1254 prerequisites to be modifier names ('export', 'private', etc.)
1256 * NEWS: Add notes about user-visible changes.
1258 * read.c (struct vmodifiers): Remember what modifiers were seen.
1259 (parse_var_assignment): New function to parse variable assignments.
1260 (eval): Call the new function. Handle variable assignments earlier.
1262 * variable.c (parse_variable_definition): Only parse; don't create var.
1263 (assign_variable_definition): Call parse, then create the var.
1265 2009-05-24 Paul Smith <psmith@gnu.org>
1267 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
1268 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
1270 2009-03-14 Eli Zaretskii <eliz@gnu.org>
1272 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
1273 Fixes Savannah bug #25412.
1275 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
1276 prototype for xmalloc.
1277 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
1278 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
1279 Loop over an array of extensions, instead of duplicating the same
1280 code inline. Use SearchPath followed by CreateFile, instead of
1281 the obsolete OpenFile. Fixes Savannah bug #17277.
1282 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
1283 to `find_file'. Fixes Savannah bug #25662.
1285 2009-03-07 Eli Zaretskii <eliz@gnu.org>
1287 * function.c (func_shell): Don't close pipedes[1] if it is -1.
1288 Fixes Savannah bug #20495.
1290 2009-02-28 Ralf Wildenhues <address@hidden>
1292 * doc/make.texi (Instead of Execution): Document interaction of
1293 -t with phony targets.
1295 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
1297 Introduce a new keyword "private" which applies to target-specific
1298 variables and prevents their values from being inherited.
1300 * variable.h (struct variable): Add private_var flag to each variable.
1301 Add a flag to specify which list entry switches to the parent target.
1302 * variable.c (define_variable_in_set): Initialize private_var flag.
1303 (lookup_variable): Skip private variables in parent contexts.
1304 (initialize_file_variables): Set next_is_parent appropriately.
1305 (print_variable): Show the private_var flag.

1315 * make.h: Rename savestring to xstrndup.
1316 * commands.c (chop_commands): Ditto.
1317 * function.c (func_foreach): Ditto.
1318 * read.c (eval, record_files): Ditto.
1319 * variable.c (define_variable_in_set): Ditto.
1321 2008-09-30 Eli Zaretskii <eliz@gnu.org>
1323 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
1326 * w32/subproc/build.bat (GCCBuild): Likewise.
1328 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
1330 * job.c (construct_command_argv_internal): Avoid extra backslash
1331 in batch-mode Unixy shells. Under DB_JOBS, display the contents
1334 2008-05-31 Eli Zaretskii <eliz@gnu.org>
1336 * README.W32.template: Remove obsolete text about non-support for
1337 -jN without Unixy shell. Remove obsolete text about not supplying
1338 Visual Studio project files (we do supply them). Modify text to
1339 prefer GCC builds to MSC builds.
1341 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1343 * doc/make.texi (Empty Targets): Fix typo.
1345 2008-03-27 Paul Smith <psmith@gnu.org>
1347 Fix Savannah bug #22379:

1355 2008-01-26 Eli Zaretskii <eliz@gnu.org>
1357 * variable.c (target_environment): Don't use shell_var if its
1358 `value' field is NULL.
1360 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1362 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
1364 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
1365 (TEXINFOS): Value changed to `doc/make.texi'.
1366 (.SUFFIXES): Use .texi instead of .texinfo.
1367 (make.info, make.dvi): Depend on doc/make.texi.
1368 (.texi.info): New target, instead of ".texinfo.info". Change -I
1369 switch to $(MAKEINFO) to look in doc/. Use --no-split.
1370 (.texi): New target, instead of ".texinfo". Change -I switch to
1371 $(MAKEINFO) to look in doc/. Use --no-split.
1372 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
1373 switch to $(MAKEINFO) to look in doc/.
1374 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
1375 "*.i[0-9][0-9]" (due to --no-split above).
1376 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
1377 (html, make_1.html): New targets.
1378 (.PHONY): Add "html".
1379 (.SUFFIXES): Add .html.
1381 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
1383 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
1384 HAVE_DECL_SYS_SIGLIST.
1386 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
1387 build does not use child_execute_job.
1389 * variable.c (define_automatic_variables) [__MSDOS__]: Always
1390 export the SHELL environment variable to the child.
1392 2007-12-22 Eli Zaretskii <eliz@gnu.org>
1394 * config.h.W32: Include sys/types.h.
1395 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
1397 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
1398 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is

1403 * doc/make.texi: Convert references to "commands", "command
1404 lines", and "command script" to "recipe".
1406 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
1409 2007-10-27 Bruno Haible <bruno@clisp.org>
1411 * remake.c (f_mtime): Print time difference values between 100 and
1412 ULONG_MAX in fixed-point notation rather than in exponention notation.
1414 2007-10-12 Eli Zaretskii <eliz@gnu.org>
1416 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
1417 a more complex value than a simple shell: if it's not a default
1418 shell now then expand it and see if is a default shell then.
1420 2007-10-10 Eli Zaretskii <eliz@gnu.org>
1422 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
1423 pathnames, with const strings.
1424 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
1425 from the template (used for building from CVS, not a dist).
1427 2007-10-10 Paul Smith <psmith@gnu.org>
1429 * make.h: Add a prototype for w32_kill() (change suggested by
1430 Yongwei Wu <wuyongwei@gmail.com>).
1432 2007-09-21 Eli Zaretskii <eliz@gnu.org>
1434 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
1435 directories in Path.
1437 2007-09-12 Paul Smith <psmith@gnu.org>

1440 Provided by Diego Biurrun <diego@biurrun.de>
1441 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
1442 Provided by Diego Biurrun <diego@biurrun.de>
1444 2007-09-11 Paul Smith <psmith@gnu.org>
1446 * doc/make.texi (Special Variables): Moved this into the "How to
1447 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
1448 (MAKEFILE_LIST) No longer a section; this was added into the
1449 "Special Variables" section.
1450 (Rule Introduction): Reference .RECIPEPREFIX.
1451 (Simple Makefile): Ditto.
1452 (Rule Syntax): Ditto.
1453 (Command Syntax): Ditto.
1454 (Error Messages): Ditto.
1456 2007-09-10 Paul Smith <psmith@gnu.org>
1458 * commands.c (print_commands): Don't print an extra line in the
1459 command scripts. Prefix the command scripts with cmd_prefix, not \t.
1461 * read.c (construct_include_path): Add the full string to the cache; we
1462 were chopping the last char.
1464 * NEWS: Announce the .RECIPEPREFIX special variable.
1465 * variable.c (lookup_special_var): Rename from handle_special_var().
1466 (lookup_variable): Call the new name.
1467 (set_special_var): New function: handle setting of special variables.
1468 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
1469 (do_variable_definition): Call it.
1470 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
1471 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
1472 * main.c (main): Create the .RECIPEPREFIX special variable.
1473 * read.c (eval): Remove the cmd_prefix characters from the command
1474 scripts here, so they're not stored in the commands array at all,
1475 rather than waiting and stripping them out during command construction.
1476 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
1478 2007-08-15 Paul Smith <psmith@gnu.org>
1480 * doc/make.texi (GNU Free Documentation License): The fdl.texi
1481 file has had the section info removed, so add some to make.texi
1482 before we include it.
1484 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
1486 * remake.c (check_dep): Reset the target state for intermediate
1487 files. They might have been considered before but not updated
1488 then (order-only for example) but they will be this time.
1489 Fixes Savannah bug #'s 3330 and 15919.
1491 2007-07-21 Eli Zaretskii <eliz@gnu.org>
1493 Fix Savannah bug #20549:
1494 * function.c (func_shell): Call construct_command_argv with zero
1496 * job.c (construct_command_argv_internal): New argument FLAGS; all
1498 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
1500 * job.h (construct_command_argv_internal): Update prototype.
1502 2007-07-13 Paul Smith <psmith@gnu.org>
1504 * file.c (expand_deps): Use variable_buffer as the start of the
1505 buffer, not the original pointer (in case it was reallocated).
1506 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
1507 Fixes Savannah bug #20452.
1509 2007-07-04 Paul Smith <psmith@gnu.org>
1511 * (ALL FILES): Update to GPLv3.
1512 * (ALL FILES): Update copyright for 2007.
1514 * main.c (print_version): Move the host type info to the second line.
1516 2007-06-29 Thiemo Seufer <ths@mips.com>
1518 * maintMakefile: Update Translation Project location.
1520 2007-06-13 Paul Smith <psmith@gnu.org>
1522 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
1523 "Expansion of a deferred"
1524 Fixes Savannah bug #20018.
1526 * expand.c (variable_expand_for_file): Preserve the value of
1527 reading_file rather than setting it to 0 at the end.
1528 Fixes Savannah bug #20033.
1530 2007-05-11 Paul Smith <psmith@gnu.org>
1532 * job.c (new_job): Add debug info to specify where make found the
1533 command script it is running to build a target.
1534 Fixes Savannah bug #18617.
1536 * default.c (default_suffixes,default_suffix_rules,default_variables):
1537 Add support for Objective C. Fixes Savannah bug #16389.
1538 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
1540 * function.c (func_lastword): Initialize p.
1542 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
1543 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
1544 Dave Korn <dave.korn@artimi.com>
1546 2007-05-08 Paul Smith <psmith@gnu.org>
1548 Fix Savannah bug #19656:
1550 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
1552 * make.h: Change all case-insensitive string compares to use
1553 strcasecmp() (from POSIX). If we don't have that but do have one
1554 of the others, define strcasecmp to be one of those instead. If
1555 we don't have any, declare a prototype for our own version.
1557 * misc.c (strcasecmp): Use this if we can't find any native
1558 case-insensitive string comparison function.
1559 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
1560 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
1562 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
1563 strcasecmp() instead of stricmp().
1564 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
1565 instead of strcmpi().
1566 * acinclude.m4: Remove the strcasecmp() check from here.
1568 2007-03-21 Paul Smith <psmith@gnu.org>
1570 * configure.in: Don't turn on case-insensitive file system support
1571 if --disable-... is given. Fixes Savannah bug #19348.
1573 2007-03-19 Paul Smith <psmith@gnu.org>
1575 * ALL: Use the strcache for all file name strings, or other
1576 strings which we will never free. The goal is to save memory by
1577 avoiding duplicate copies of strings. However, at the moment this
1578 doesn't save much memory in most situations: due to secondary
1579 expansion we actually save prerequisite lists twice (once before
1580 the secondary expansion, and then again after it's been parsed
1581 into individual file names in the dep list). We will resolve this
1582 in a future change, by doing the parsing up-front for targets
1583 where secondary expansion is not set.
1585 Moving things into the strcache also allows us to use const
1586 pointers in many more places.
1588 2007-01-03 Paul Smith <psmith@gnu.org>
1590 * make.h (ENULLLOOP): Reset errno after each failed invocation of
1591 the function, not just the first. Fixes Savannah bug #18680.
1593 2006-11-18 Paul Smith <psmith@gnu.org>
1595 * strcache.c (strcache_add_len): Don't allocate a new buffer
1596 unless the string is not already nil-terminated. Technically this
1597 is a violation of the standard, since we may be passed an array
1598 that is not long enough to test one past. However, in make this
1599 is never true since we only use nil-terminated strings or
1600 sub-strings thereof.
1602 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
1604 * main.c: New global cmd_prefix, defaults to '\t'.
1605 * job.c (construct_command_argv_internal): Use cmd_prefix instead
1608 * dir.c: Constified.
1609 (dir_contents_file_exists_p): Check for an error return from
1610 readdir(), just in case.

1631 2006-10-21 Paul Smith <psmith@gnu.org>
1634 * arscan.c: Constified.
1636 2006-09-30 Paul Smith <psmith@gnu.org>
1638 * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
1639 point to lastword since the example was updated.
1640 Fixes Savannah bug #16304.
1641 (Secondary Expansion): Correct example description.
1642 Fixes Savannah bug #16468.
1643 (Makefile Contents): Clarify that comments cannot appear within
1644 variable references or function calls.
1645 Fixes Savannah bug #16577.
1646 (Special Targets): Clarify how .NOTPARALLEL works in recursion.
1647 Fixes Savannah bug #17701.
1648 Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:

1650 prerequisites. Fixes Savannah bug #17880.
1651 (Rule Syntax): "lise" -> "list"
1652 (Multiple Rules): ... -> @dots{}
1653 (Splitting Lines): ditto.
1655 * remake.c (update_file_1): Prereqs that don't exist should be
1656 considered changed, for the purposes of $?.
1657 Fixes Savannah bug #16051.

1696 2006-04-20 Paul D. Smith <psmith@gnu.org>
1698 * maintMakefile (po-check): Use Perl instead of grep -E, for systems
1699 that don't have extended grep.
1700 (cvsclean): Use $(PERL) instead of perl.
1702 2006-04-09 Paul D. Smith <psmith@gnu.org>
1704 * maintMakefile: Add some extra warning options (GCC 4.1 only?)
1706 * expand.c, implicit.c, main.c, read.c: Rename variables so that
1707 inner-scope variables don't mask outer-scope variables.
1709 * ar.c, arscan.c, commands.c, default.c, dir.c, expand.c, file.c:

1712 * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
1713 values from memory allocation functions: they return void* and so
1714 don't need to be cast. Also remove (char *) casts of arguments to

1729 2006-04-06 Paul D. Smith <psmith@gnu.org>

1732 require an ISO C 1989 standard compiler and runtime library.

1746 2006-04-01 Paul D. Smith <psmith@gnu.org>
1748 Version 3.81 released.
1750 * NEWS: Updated for 3.81.
1752 * README.cvs: Mention that vpath builds are not supported out of
1753 CVS. Fixes Savannah bug #16236.
1754 Remove update of make.texi from the list of things to do; we use
1757 2006-03-26 Paul D. Smith <psmith@gnu.org>

1760 support from automake, as described in the Texinfo manual.
1762 2006-03-25 Eli Zaretskii <eliz@gnu.org>
1764 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
1765 with lastslash, since the latter points to filename, not to

1768 Declare and define sh_chars_sh[].
1770 2006-03-23 Paul D. Smith <psmith@gnu.org>
1772 * configure.in: Look for build.sh.in in $srcdir so it will be
1773 built for remote configurations as well.
1775 * Makefile.am: Make sure to clean up build.sh during distclean.
1776 Fixes Savannah bug #16166.
1778 * misc.c (log_access): Takes a const char *.
1779 * function.c (fold_newlines): Takes an unsigned int *.
1780 Both fixes for Savannah bug #16170.
1782 2006-03-22 Boris Kolpackov <boris@kolpackov.net>
1784 * implicit.c (pattern_search): Call set_file_variables only
1785 if we have prerequisites that need second expansion. Fixes
1786 Savannah bug #16140.
1788 2006-03-19 Paul D. Smith <psmith@gnu.org>
1790 * remake.c (update_file): Add alloca(0) to clean up alloca'd
1791 memory on hosts that don't support it directly.
1793 * README.cvs: Add information on steps for making a release (to
1794 make sure I don't forget any).
1796 * main.c (clean_jobserver): Move jobserver cleanup code into a new
1798 (die): Cleanup code was removed from here; call the new function.
1799 (main): If we are re-execing, clean up the jobserver first so we
1800 don't leak file descriptors.

1803 2006-03-17 Paul D. Smith <psmith@gnu.org>
1805 * maintMakefile (do-po-update): Rewrite this rule to clean up and
1806 allow multiple concurrent runs.
1807 Patch from Joseph Myers <joseph@codesourcery.com>
1809 2006-03-17 Boris Kolpackov <boris@kolpackov.net>
1811 * dep.h (struct dep): Add the stem field.
1812 * misc.c (alloc_dep, free_dep): New functions.
1813 (copy_dep_chain): Copy stem.
1814 (free_dep_chain): Use free_dep.
1815 * read.c (record_files): Store stem in the dependency line.
1816 * file.c (expand_deps): Use stem stored in the dependency line. Use
1817 free_dep_chain instead of free_ns_chain.
1818 * implicit.c (pattern_search): Use alloc_dep and free_dep.
1819 * read.c (read_all_makefiles, eval_makefile, eval): Ditto.
1820 * main.c (main, handle_non_switch_argument): Ditto.

1824 2006-03-14 Paul D. Smith <psmith@gnu.org>
1826 * expand.c (variable_append): Instead of appending everything then
1827 expanding the result, we expand (or not, if it's simple) each part
1829 (allocated_variable_append): Don't expand the final result.
1830 Fixes Savannah bug #15913.
1832 2006-03-09 Paul Smith <psmith@gnu.org>
1834 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
1835 listed non-existent files as changed. Turns out there's a bug in
1836 the Linux kernel builds which means that this change causes
1837 everything to rebuild every time. We will re-introduce this fix
1838 in the next release, to give them time to fix their build system.
1839 Fixes Savannah bug #16002.
1840 Introduces Savannah bug #16051.
1842 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

1855 to be null; don't core in that case.
1857 2006-02-19 Paul D. Smith <psmith@gnu.org>
1859 * commands.c (set_file_variables): Realloc, not malloc, the static
1860 string values to avoid memory leaks.
1862 * expand.c (recursively_expand_for_file): Only set reading_file to
1863 an initialized value.
1865 * implicit.c (pattern_search): We need to make a copy of the stem
1866 if we get it from an intermediate dep, since those get freed.
1868 * file.c (lookup_file) [VMS]: Don't lowercase special targets that
1870 (enter_file) [VMS]: Ditto.
1871 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
1873 2006-02-24 Eli Zaretskii <eliz@gnu.org>
1875 * job.c (construct_command_argv_internal): Fix last change.
1877 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
1878 dwStdout, and dwStderr unsigned int: avoids compiler warnings in
1879 the calls to _beginthreadex.
1881 * expand.c (recursively_expand_for_file): Initialize `save' to
1882 prevent compiler warnings.
1884 2006-02-18 Eli Zaretskii <eliz@gnu.org>
1886 * job.c (construct_command_argv_internal): Don't create a temporary
1887 script/batch file if we are under -n. Call _setmode to switch the
1888 script file stream to text mode.
1890 2006-02-17 Paul D. Smith <psmith@gnu.org>
1892 * variable.c (merge_variable_set_lists): Don't try to merge the
1893 global_setlist. Not only is this useless, but it can lead to
1894 circularities in the linked list, if global_setlist->next in one
1895 list gets set to point to another list which also ends in
1897 Fixes Savannah bug #15757.
1899 2006-02-15 Paul D. Smith <psmith@gnu.org>
1901 Fix for Savannah bug #106.
1903 * expand.c (expanding_var): Keep track of which variable we're
1904 expanding. If no variable is being expanded, it's the same as
1906 * make.h (expanding_var): Declare it.
1907 * expand.c (recursively_expand_for_file): Set expanding_var to the
1908 current variable we're expanding, unless there's no file info in
1909 it (could happen if it comes from the command line or a default
1910 variable). Restore it before we exit.
1911 * expand.c (variable_expand_string): Use the expanding_var file
1912 info instead of the reading_file info.

1922 * read.c (eval): Even if the included filenames expands to the
1923 empty string we still need to free the allocated buffer.
1925 * implicit.c (pattern_search): If we allocated a variable set for
1926 an impossible file, free it.
1927 * variable.c (free_variable_set): New function.
1928 * variable.h: Declare it.
1930 * read.c (read_all_makefiles): Makefile names are kept in the
1931 strcache, so there's never any need to alloc/free them.
1934 * main.c (main): Add "archives" to the .FEATURES variable if
1935 archive support is enabled.
1936 * doc/make.texi (Special Variables): Document it.
1938 2006-02-13 Paul D. Smith <psmith@gnu.org>

1946 * (ALL FILES): Updated copyright and license notices.
1948 2006-02-10 Paul D. Smith <psmith@gnu.org>
1950 A new internal capability: the string cache is a read-only cache
1951 of strings, with a hash table interface for fast lookup. Nothing
1952 in the cache will ever be freed, so there's no need for reference
1953 counting, etc. This is the beginning of a full solution for
1954 Savannah bug #15182, but for now we only store makefile names here.
1956 * strcache.c: New file. Implement a read-only string cache.
1957 * make.h: Add prototypes for new functions.
1958 * main.c (initialize_global_hash_tables): Initialize the string cache.
1959 (print_data_base): Print string cache stats.
1960 * read.c (eval_makefile): Use the string cache to store makefile
1961 names. Rewrite the string allocation to be sure we free everything.
1963 2006-02-10 Eli Zaretskii <eliz@gnu.org>
1965 * dir.c (dir_contents_file_exists_p): Don't opendir if the
1966 directory time stamp didn't change, except on FAT filesystems.
1967 Suggested by J. David Bryan <jdbryan@acm.org>.

1972 (func_and): Implement a short-circuiting AND function.
1973 (function_table_init): Update the table with the new functions.
1974 * doc/make.texi (Conditional Functions): Changed the "if" section
1975 to one on general conditional functions. Added documentation for
1976 $(and ...) and $(or ...) functions.

1988 * vpath.c (selective_vpath_search): If the file we find has a
1989 timestamp from -o or -W, use that instead of the real time.
1990 * remake.c (f_mtime): If the mtime is a special token from -o or
1991 -W, don't overwrite it with the real mtime.

1997 (process_signal, process_last_err, process_exit_code): Manage
1998 invalid handle values.

2009 Fixes Savannah bug #15533.
2010 * filedef.h (struct file): Add a new LAST pointer.
2012 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
2013 the comparison. For 64-bits systems the result of the subtraction
2014 might not fit into an int. Use comparison instead.
2015 Fixes Savannah bug #15534.
2017 * doc/make.texi: Update the chapter on writing commands to reflect
2018 the changes made in 3.81 for backslash/newline and SHELL handling.
2020 2006-02-01 Paul D. Smith <psmith@gnu.org>
2022 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
2023 variable st is not used when it's not initialized.
2024 Patch from Eli Zaretskii <eliz@gnu.org>.

2038 2006-01-21 Eli Zaretskii <eliz@gnu.org>
2040 * remake.c (update_goal_chain): Set g->changed instead of
2041 incrementing it, as it is only 8-bit wide, and could overflow if
2042 many commands got started in update_file.

2046 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

2063 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
2064 the shell is not sh.exe.
2066 * job.c (create_batch_file): Renamed from create_batch_filename;
2067 all callers changed. Don't close the temporary file; return its
2068 file descriptor instead. New arg FD allows to return the file
2070 (construct_command_argv_internal): Use _fdopen instead of fopen to
2071 open the batch file.
2073 2006-01-04 Paul D. Smith <psmith@gnu.org>
2075 * readme.vms: Updates for case-insensitive VMS file systems from

2094 2005-12-28 Paul D. Smith <psmith@gnu.org>
2096 * config.h.W32.template [WINDOWS32]: Add in some pragmas to
2097 disable warnings for MSC.
2098 Patch by Rob Tulloh <rtulloh@yahoo.com>.
2100 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2102 * doc/make.texi (Execution): Add a footnote about changes in
2103 handling of backslash-newline sequences. Mention the differences
2104 on MS-DOS and MS-Windows.
2106 * NEWS: More details about building the MinGW port and a pointer
2107 to README.W32. Fix the section name that describes the new
2108 backward-incompatible processing of backslash-newline sequences.
2109 The special processing of SHELL set to "cmd" is only relevant to
2110 MS-Windows, not MS-DOS.
2112 2005-12-17 Eli Zaretskii <eliz@gnu.org>
2114 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
2115 to DWORD, to avoid compiler warnings.
2116 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
2117 use %ld in format, to avoid compiler warnings.
2119 * doc/make.texi (Special Targets): Fix a typo.
2120 (Appending): Fix cross-reference to Setting.
2121 (Special Variables, Secondary Expansion, File Name Functions)
2122 (Flavor Function, Pattern Match, Quick Reference): Ensure two
2123 periods after a sentence.
2124 (Execution): Add @: after "e.g.".
2125 (Environment): Fix punctuation.
2126 (Target-specific, Call Function, Quick Reference): Add @: after "etc."
2127 (Shell Function, Target-specific): Add @: after "vs."
2129 2005-12-14 Boris Kolpackov <boris@kolpackov.net>
2131 * read.c (record_target_var): Initialize variable's export field
2132 with v_default instead of leaving it "initialized" by whatever
2133 garbage happened to be on the heap.
2135 2005-12-12 Paul D. Smith <psmith@gnu.org>
2137 * make.1: Fix some display errors and document all existing options.
2138 Patch by Mike Frysinger <vapier@gentoo.org>.
2140 2005-12-11 Paul D. Smith <psmith@gnu.org>
2142 * implicit.c (pattern_search): If 2nd expansion is not set for
2143 this implicit rule, replace the pattern with the stem directly,
2144 and don't re-expand the variable list. Along with the other
2145 .SECONDEXPANSION changes below, fixes bug #13781.
2147 2005-12-09 Boris Kolpackov <boris@kolpackov.net>
2149 * implicit.c (pattern_search): Mark other files that this rule
2150 builds as targets so that they are not treated as intermediates
2151 by the pattern rule search algorithm. Fixes bug #13022.
2153 2005-12-07 Boris Kolpackov <boris@kolpackov.net>
2155 * remake.c (notice_finished_file): Propagate the change of
2156 modification time to all the double-colon entries only if
2157 it is the last one to be updated. Fixes bug #14334.
2159 2005-11-17 Boris Kolpackov <boris@kolpackov.net>
2161 * function.c (func_flavor): Implement the flavor function which
2162 returns the flavor of a variable.
2163 * doc/make.texi (Functions for Transforming Text): Document it.
2164 * NEWS: Add it to the list of new functions.
2166 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
2168 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
2170 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
2171 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
2173 2005-10-26 Paul Smith <psmith@gnu.org>
2175 * read.c (record_files): Don't set deps flags if there are no deps.
2176 * maintMakefile: We only need to build the templates when we are
2177 creating a distribution, so don't do it for "all".
2179 2005-10-24 Paul D. Smith <psmith@gnu.org>
2181 Make secondary expansion optional: its enabled by declaring the
2182 special target .SECONDEXPANSION.
2184 * NEWS: Update information on second expansion capabilities.
2185 * doc/make.texi (Secondary Expansion): Document the
2186 .SECONDEXPANSION special target and its behavior.
2187 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
2188 prerequisite list was found in a static pattern rule.
2189 (free_dep_chain): Declare a prototype.
2190 * file.c (parse_prereqs): New function: break out some complexity
2192 (expand_deps): If we aren't doing second expansion, replace % with
2193 the stem for static pattern rules. Call the new function.
2194 * filedef.h (parse_prereqs): Declare a prototype.
2195 * implicit.c (pattern_search): Initialize the new staticpattern
2197 * main.c (second_expansion): Declare a global variable to remember
2198 if the special target has been seen. Initialize the new
2199 staticpattern field for prerequisites.
2200 * make.h: Extern for second_expansion.
2201 * misc.c (free_dep_chain): New function: frees a struct dep list.
2202 * read.c (read_all_makefiles): Initialize the staticpattern field.
2203 (eval_makefile): Ditto.
2204 (record_files): Check for the .SECONDEXPANSION target and set
2205 second_expansion global if it's found.
2206 Use the new free_dep_chain() instead of doing it by hand.
2207 Set the staticpattern field for prereqs of static pattern targets.
2209 2005-10-16 Paul D. Smith <psmith@gnu.org>
2211 * main.c (main): Set CURDIR to be a file variable instead of a
2212 default, so that values of CURDIR inherited from the environment
2213 won't override the make value.
2215 2005-09-26 Paul D. Smith <psmith@gnu.org>
2217 * job.c (construct_command_argv_internal): If the line is empty
2218 remember to free the temporary argv strings.
2221 2005-09-16 Paul D. Smith <psmith@gnu.org>
2223 * job.c (start_job_command): The noerror flag is a boolean (single
2224 bit); set it appropriately.
2225 Reported by Mark Eichin <eichin@metacarta.com>
2227 2005-08-29 Paul D. Smith <psmith@gnu.org>
2229 * function.c (func_error): On Windows, output from $(info ...)
2230 seems to come in the wrong order. Try to force it with fflush().
2232 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
2234 * read.c (record_files): Move code that sets stem for static
2235 pattern rules out of the if (!two_colon) condition so it is
2236 also executed for two-colon rules. Fixes Savannah bug #13881.
2238 2005-08-08 Paul D. Smith <psmith@gnu.org>
2240 * make.h: Don't test that __STDC__ is non-0. Some compilers
2241 (Windows for example) set it to 0 to denote "ISO C + extensions".
2244 2005-08-07 Paul D. Smith <psmith@gnu.org>
2246 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
2247 conditional (slightly different version of a fix from Eli).
2249 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
2250 If make is running in parallel without -k and two jobs die in a
2251 row, but not too close to each other, then make will quit without
2252 waiting for the rest of the jobs to die.
2254 * main.c (die): Don't reset err before calling reap_children() the
2255 second time: we still want it to be in the error condition.
2256 * job.c (reap_children): Use a static variable, rather than err,
2257 to control whether or not the error message should be printed.
2259 2005-08-06 Eli Zaretskii <eliz@gnu.org>
2261 * w32/subproc/sub_proc.c: Include signal.h.
2262 (process_pipe_io, process_file_io): Pass a pointer to a local
2263 DWORD variable to GetExitCodeProcess. If the exit code is
2264 CONTROL_C_EXIT, put SIGINT into pproc->signal.
2266 * job.c [WINDOWS32]: Include windows.h.
2267 (main_thread) [WINDOWS32]: New global variable.
2268 (reap_children) [WINDOWS32]: Get the handle for the main thread
2269 and store it in main_thread.
2271 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
2272 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
2273 doing anything else. When we are done, close the main thread
2274 handle and exit with status 130.
2276 2005-07-30 Eli Zaretskii <eliz@gnu.org>
2278 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
2281 * main.c (find_and_set_default_shell): If found a DOSish shell,
2282 set sh_found and the value of default_shell, and report the
2283 findings in debug mode.
2285 * job.c (construct_command_argv_internal): Check unixy_shell, not
2286 no_default_sh_exe, to decide whether to use Unixy or DOSish
2289 * README.W32: Update with info about the MinGW build.
2291 * build_w32.bat: Support MinGW.
2293 * w32/subproc/build.bat: Likewise.
2295 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
2296 printing DWORD args.
2298 * function.c (windows32_openpipe): Fix format strings for printing
2301 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
2303 (start_job_command): Fix format string for printing the result of
2305 (start_job_command) [WINDOWS32]: Do not define.
2306 (exec_command): Fix format string for printing HANDLE args.
2308 * main.c (handle_runtime_exceptions): Fix sprintf format strings
2309 to avoid compiler warnings.
2310 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
2311 (Note: some of these fixes were submitted independently by J. Grant)
2313 2005-07-30 J. Grant <jg@jguk.org>
2315 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
2316 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
2317 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
2319 2005-07-15 Paul Smith <psmith@gnu.org>
2321 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
2322 we don't have a POSIX shell, then revert to the old
2323 backslash-newline behavior (where they are stripped).
2326 2005-07-08 Paul D. Smith <psmith@gnu.org>
2328 * config.h.W32.template: Reorder to match the standard config.h,
2329 for easier comparisons.
2330 From J. Grant <jg@jguk.org>
2332 * maintMakefile: Remove .dep_segment before overwriting it, in
2333 case it's not writable or noclobber is set.
2334 * expand.c (variable_expand_string): Cast result of pointer
2335 arithmetic to avoid a warning.
2336 * main.c (switches): Add full-fledged final initializer.
2338 2005-07-06 Paul D. Smith <psmith@gnu.org>
2340 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
2341 * signame.c (strsignal): If we found _sys_siglist[] or
2342 __sys_siglist[] use those instead of sys_siglist[].
2343 From Albert Chin <china@thewrittenword.com>
2345 2005-07-04 Paul D. Smith <psmith@gnu.org>
2347 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
2348 globfree(); set up to use the GNU versions.
2349 From Martin Zinser <zinser@zinser.no-ip.info>
2351 2005-07-03 Paul D. Smith <psmith@gnu.org>
2353 From J. Grant <jg@jguk.org>:
2355 * README.W32.template: Update the Windows and tested MSVC versions.
2356 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
2357 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
2358 * build_w32.bat: Ditto.
2359 * w32/subproc/build.bat: Ditto.
2361 2005-06-28 Paul D. Smith <psmith@gnu.org>
2363 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
2364 declaration was checked but not present.
2366 2005-06-27 Paul D. Smith <psmith@gnu.org>
2368 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
2369 to unsigned long. Fixes Savannah bug #13550.
2371 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
2372 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
2373 Fixes Savannah bug #13551.
2375 2005-06-26 Paul D. Smith <psmith@gnu.org>
2377 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
2378 it if ANSI_STRING is not set.
2380 2005-06-25 Paul D. Smith <psmith@gnu.org>
2382 * read.c (eval): If no filenames are passed to any of the
2383 "include" variants, don't print an error.
2384 * doc/make.texi (Include): Document this.
2385 Fixes Savannah bug #1761.
2387 * job.c (construct_command_argv_internal): Sanitize handling of
2388 backslash/newline pairs according to POSIX: that is, keep the
2389 backslash-newline in the command script, but remove a following
2390 TAB character, if present. In the fast path, make sure that the
2391 behavior matches what the shell would do both inside and outside
2392 of quotes. In the slow path, quote the backslash and put a
2393 literal newline in the string.
2394 Fixes Savannah bug #1332.
2395 * doc/make.texi (Execution): Document the new behavior and give
2397 * NEWS: Make a note of the new behavior.
2399 * make.h [WINDOWS32]: #include <direct.h>.
2400 Fixes Savannah bug #13478.
2402 * remake.c (name_mtime): If the stat() of a file fails and the -L
2403 option was given and the file is a symlink, take the best mtime of
2404 the symlink we can get as the mtime of the file and don't fail.
2405 Fixes Savannah bug #13280.
2407 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
2408 If it's set, then don't stop on STOPCHARs or BLANKs if they're
2409 inside a variable reference. Make this function static as it's
2411 (eval): Call find_char_unquote() with IGNOREVARS set when we're
2412 parsing an unexpanded line looking for semicolons.
2413 Fixes Savannah bug #1454.
2414 * misc.c (remove_comments): Move this to read.c and make it static
2415 as it's only used there. Call find_char_unquote() with new arg.
2416 * make.h: Remove prototypes for find_char_unquote() and
2417 remove_comments() since they're static now.
2419 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
2420 its export flag and obtain its value. When we need to re-exec,
2421 increment the value and add it into the environment.
2422 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
2423 * NEWS: Mention MAKE_RESTARTS.
2424 * main.c (always_make_set): New variable. Change the -B option to
2425 set this one instead.
2426 (main): When checking makefiles, only set always_make_flag if
2427 always_make_set is set AND the restarts flag is 0. When building
2428 normal targets, set it IFF always_make_set is set.
2429 (main): Avoid infinite recursion with -W, too: only set what-if
2430 files to NEW before we check makefiles if we've never restarted
2431 before. If we have restarted, set what-if files to NEW _after_ we
2433 Fixes Savannah bug #7566:
2435 2005-06-17 Paul D. Smith <psmith@gnu.org>
2437 * default.c: Change VMS implicit rules to use $$$$ instead of $$
2438 in the prerequisites list.
2440 2005-06-12 Paul D. Smith <psmith@gnu.org>
2442 Fix Savannah bug # 1328.
2444 * configure.in: Check for atexit().
2445 * misc.c (close_stdout): Test stdout to see if writes to it have
2446 failed. If so, be sure to exit with a non-0 error code. Based on
2447 code found in gnulib.
2448 * make.h: Prototype.
2449 * main.c (main): Install close_stdout() with atexit().
2451 2005-06-10 Paul D. Smith <psmith@gnu.org>
2453 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
2455 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
2456 headers; make vmsWaitForChildren() static; extern vmsify().
2457 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
2458 Don't create child_execute_job() here (it's in vmsjobs.c).
2459 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2461 2005-06-09 Paul D. Smith <psmith@gnu.org>
2463 * variable.c (push_new_variable_scope): File variables point
2464 directly to the global_setlist variable. So, inserting a new
2465 scope in front of that has no effect on those variables: they
2466 don't go through current_variable_set_list. If we're pushing a
2467 scope and the current scope is global, push it "the other way" so
2468 that the new setlist is in the global_setlist variable, and
2469 next points to a new setlist with the global variable set.
2470 (pop_variable_scope): Properly undo a push with the new
2472 Fixes Savannah bug #11913.
2474 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
2476 * job.c (reap_children): Don't die of the command failed but
2477 the dontcare flag is set. Fixes Savannah bug #13216.
2479 * implicit.c (pattern_search): When creating a target from
2480 an implicit rule match, lookup pattern target and set precious
2481 flag in a newly created target. Fixes Savannah bug #13218.
2483 2005-05-13 Paul D. Smith <psmith@gnu.org>
2485 Implement "if... else if... endif" syntax.
2487 * read.c (eval): Push all checks for conditional words ("ifeq",
2488 "else", etc.) down into the conditional_line() function.
2489 (conditional_line): Rework to allow "else if..." clause. New
2490 return value -2 for lines which are not conditionals. The
2491 ignoring flag can now also be 2, which means "already parsed a
2492 true branch". If that value is seen no other branch of this
2493 conditional can be considered true. In the else parsing if there
2494 is extra text after the else, invoke conditional_line()
2495 recursively to see if it's another conditional. If not, it's an
2496 error. If so, raise the conditional value to this level instead
2497 of creating a new conditional nesting level. Special check for
2498 "else" and "endif", which aren't allowed on the "else" line.
2499 * doc/make.texi (Conditional Syntax): Document the new syntax.
2501 2005-05-09 Paul D. Smith <psmith@gnu.org>
2503 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
2504 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
2505 recurses to the w32 directory, even on non-Windows systems. Use
2506 the method suggested in the automake manual.
2507 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
2508 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
2510 2005-05-07 Paul D. Smith <psmith@gnu.org>
2512 * main.c (die): If we're dying with a fatal error (not that a
2513 command has failed), write back any leftover tokens before we go.
2515 * job.c (set_child_handler_action_flags): If there are jobs
2516 waiting for the load to go down, set an alarm to go off in 1
2517 second. This allows us to wake up from a potentially long-lasting
2518 read() and start a new job if the load has gone down. Turn it off
2520 (job_noop): Dummy signal handler function.
2521 (new_job): Invoke it with the new semantics.
2523 * docs/make.texi: Document secondary expansion. Various cleanups
2526 2005-05-03 Paul D. Smith <psmith@gnu.org>
2528 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
2529 the targets which are to ultimately be made are called "goals";
2530 see the GNU make manual. Also, MAKECMDGOALS, etc.
2532 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
2533 .DEFAULT_GOAL, and default_target_name to default_goal_name.
2534 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2536 2005-05-02 Paul D. Smith <psmith@gnu.org>
2538 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
2539 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
2540 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
2541 functions to vmsjobs.c. #include it into jobs.c.
2543 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
2544 jobserver tokens. I found that this happens when an exported
2545 recursive variable contains a $(shell ...) function reference: in
2546 this situation we could "forget" to write back a token.
2548 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
2549 we have. It's not reliable to depend on the number of children in
2550 our linked list so keep a separate count.
2551 (new_job): Check jobserver_tokens rather than children &&
2552 waiting_jobs. Increment jobserver_tokens when we get one.
2553 (free_child): If jobserver_tokens is 0, internal error. If it's
2554 >1, write a token back to the jobserver pipe (we don't write a
2555 token for the "free" job). Decrement jobserver_tokens.
2557 * main.c: Add variable master_job_slots.
2558 (main): Set it to hold the number of jobs requested if we're the
2559 master process, when using the jobserver.
2560 (die): Sanity checks: first test jobserver_tokens to make sure
2561 this process isn't holding any tokens we didn't write back.
2562 Second, if master_job_slots is set count the tokens left in the
2563 jobserver pipe and ensure it's the same as master_job_slots (- 1).
2565 2005-04-24 Paul D. Smith <psmith@gnu.org>
2567 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
2568 with -l# can lose jobserver tokens, because waiting jobs are not
2569 consulted properly when checking for the "free" token.
2571 * job.c (free_child): Count waiting_jobs as having tokens.
2572 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
2573 handle jobs waiting for the load to drop.
2575 2005-04-23 Paul D. Smith <psmith@gnu.org>
2577 * main.c (main): Be careful to not core if a variable setting in
2578 the environment doesn't contain an '='. This is illegal but can
2579 happen in broken setups.
2580 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2582 2005-04-12 Paul D. Smith <psmith@gnu.org>
2584 The second expansion feature causes significant slowdown. Timing
2585 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
2586 read the makefile before the feature, to 11+s to do the same
2587 operations after the feature. Additionally, memory usage
2588 increased drastically. To fix this I added some intelligence that
2589 avoids the overhead of the second expansion unless it's required.
2591 * dep.h: Add a new boolean field, need_2nd_expansion.
2593 * read.c (eval): When creating the struct dep for the target,
2594 check if the name contains a "$"; if so set need_2nd_expansion to 1.
2595 (record_files): If there's a "%" in a static pattern rule, it gets
2596 converted to "$*" so set need_2nd_expansion to 1.
2598 * file.c (expand_deps): Rework to be more efficient. Only perform
2599 initialize_file_variables(), set_file_variables(), and
2600 variable_expand_for_file() if the need_2nd_expansion is set.
2602 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
2603 (pattern_search): Ditto.
2604 * main.c (handle_non_switch_argument): Ditto.
2606 * read.c (read_all_makefiles): Ditto.
2607 (eval_makefile): Ditto.
2609 2005-04-07 Paul D. Smith <psmith@gnu.org>
2611 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
2612 * variable.c (sync_Path_environment): Ditto.
2613 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
2615 * main.c (main): Define the .FEATURES variable.
2616 * NEWS: Announce .FEATURES.
2617 * doc/make.texi (Special Variables): Document .FEATURES.
2619 * remake.c (check_dep): If a file is .PHONY, update it even if
2620 it's marked intermediate. Fixes Savannah bug #12331.
2622 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
2624 * file.c (expand_deps): Factor out the second expansion and
2625 prerequisite line parsing logic from snap_deps().
2627 * file.c (snap_deps): Use expand_deps(). Expand and parse
2628 prerequisites of the .SUFFIXES special target first. Fixes
2629 Savannah bug #12320.
2631 2005-03-13 Paul D. Smith <psmith@gnu.org>
2633 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
2636 2005-03-11 Paul D. Smith <psmith@gnu.org>
2638 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
2639 available, not undefined (from Earnie Boyd).
2641 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
2643 * implicit.c (pattern_search): Mark an intermediate target as
2644 precious if it happened to be a prerequisite of some (other)
2645 target. Fixes Savannah bug #12267.
2647 2005-03-09 Paul D. Smith <psmith@gnu.org>
2649 * read.c (eval_makefile): Add alloca(0).
2650 (eval_buffer): Ditto.
2652 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
2654 * main.c (main): Use o_file instead of o_default when defining
2655 the .DEFAULT_TARGET special variable.
2656 * read.c (eval): Use define_variable_global() instead of
2657 define_variable() when setting new value for the .DEFAULT_TARGET
2658 special variable. Fixes Savannah bug #12266.
2660 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
2662 * imlicit.c (pattern_search): Mark files for which an implicit
2663 rule has been found as targets. Fixes Savannah bug #12202.
2665 2005-03-04 Paul D. Smith <psmith@gnu.org>
2668 * doc/make.texi (Automatic Variables): Document $|.
2670 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
2672 * read.c (record_files): Instead of substituting % with
2673 actual stem value in dependency list replace it with $*.
2674 This fixes stem triple expansion bug.
2676 * implicit.c (pattern_search): Copy stem to a separate
2677 buffer and make it a properly terminated string. Assign
2678 this buffer instead of STEM (which is not terminated) to
2679 f->stem. Instead of substituting % with actual stem value
2680 in dependency list replace it with $*. This fixes stem
2681 triple expansion bug.
2683 2005-03-01 Paul D. Smith <psmith@gnu.org>
2685 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
2686 on Windows, as it takes a handle not a pid. Just exit.
2687 Fix from patch #3679, provided by Alessandro Vesely.
2689 * configure.in: Update check for sys_siglist[] from autoconf manual.
2690 * signame.c (strsignal): Update to use the new autoconf macro.
2692 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
2694 * read.c (record_files): Add a check for the list of prerequisites
2695 of a static pattern rule being empty. Fixes Savannah bug #12180.
2697 2005-02-28 Paul D. Smith <psmith@gnu.org>
2699 * doc/make.texi (Text Functions): Update docs to allow the end
2700 ordinal for $(wordlist ...) to be 0.
2701 * function.c (func_wordlist): Fail if the start ordinal for
2702 $(wordlist ...) is <1. Matches documentation.
2703 Resolves Savannah support request #103195.
2705 * remake.c (update_goal_chain): Fix logic for stopping in -q:
2706 previously we were stopping when !-q, exactly the opposite. This
2707 has been wrong since version 1.34, in 1994!
2708 (update_file): If we got an error don't break out to run more
2709 double-colon rules: just return immediately.
2710 Fixes Savannah bug #7144.
2712 2005-02-27 Paul D. Smith <psmith@gnu.org>
2714 * misc.c (end_of_token): Make argument const.
2715 * make.h: Update prototype.
2717 * function.c (abspath, func_realpath, func_abspath): Use
2718 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
2719 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
2720 * read.c (record_files): Ditto.
2721 * variable.c (do_variable_definition): Ditto.
2723 * function.c (func_error): Create a new function $(info ...) that
2724 simply prints the message to stdout with no extras.
2725 (function_table_init): Add new function to the table.
2726 * NEWS: Add $(info ...) reference.
2727 * doc/make.texi (Make Control Functions): Document it.
2729 New feature: if the system supports symbolic links, and the user
2730 provides the -L/--check-symlink-time flag, then use the latest
2731 mtime between the symlink(s) and the target file.
2733 * configure.in (MAKE_SYMLINKS): Check for lstat() and
2734 readlink(). If both are available, define MAKE_SYMLINKS.
2735 * main.c: New variable: check_symlink_flag.
2736 (usage): Add a line for -L/--check-symlink-times to the help string.
2737 (switches): Add -L/--check-symlink-times command line argument.
2738 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
2739 print a warning and disable it again.
2740 * make.h: Declare check_symlink_flag.
2741 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
2742 if the file is a symlink then check each link in the chain and
2743 choose the NEWEST mtime we find as the mtime for the file. The
2744 newest mtime might be the file itself!
2745 * NEWS: Add information about this new feature.
2746 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
2748 Avoid core dumps described in Savannah bug # 12124:
2750 * file.c: New variable snapped_deps remember whether we've run
2752 (snap_deps): Set it.
2753 * filedef.h: Extern it.
2754 * read.c (record_files): Check snapped_deps; if it's set then
2755 we're trying to eval a new target/prerequisite relationship from
2756 within a command script, which we don't support. Fatal.
2758 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
2760 Implementation of the .DEFAULT_TARGET special variable.
2762 * read.c (eval): If necessary, update default_target_name when
2764 * read.c (record_files): Update default_target_file if
2765 default_target_name has changed.
2766 * main.c (default_target_name): Define.
2767 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
2768 default_target_name is set use default_target_file as a root
2770 * filedef.h (default_target_name): Declare.
2771 * dep.h (free_dep_chain):
2772 * misc.c (free_dep_chain): Change to operate on struct nameseq
2773 and change name to free_ns_chain.
2774 * file.c (snap_deps): Update to use free_ns_chain.
2776 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
2778 Implementation of the second expansion in explicit rules,
2779 static pattern rules and implicit rules.
2781 * read.c (eval): Refrain from chopping up rule's dependencies.
2782 Store them in a struct dep as a single dependency line. Remove
2783 the code that implements SySV-style automatic variables.
2785 * read.c (record_files): Adjust the code that handles static
2786 pattern rules to expand all percents instead of only the first
2787 one. Reverse the order in which dependencies are stored so that
2788 when the second expansion reverses them again they appear in
2789 the makefile order (with some exceptions, see comments in
2790 the code). Remove the code that implements SySV-style automatic
2793 * file.c (snap_deps): Implement the second expansion and chopping
2794 of dependency lines for explicit rules.
2796 * implicit.c (struct idep): Define an auxiliary data type to hold
2797 implicit rule's dependencies after stem substitution and
2800 * implicit.c (free_idep_chain): Implement.
2802 * implicit.c (get_next_word): Implement helper function for
2803 parsing implicit rule's dependency lines into words taking
2804 into account variable expansion requests. Used in the stem
2807 * implicit.c (pattern_search): Implement the second expansion
2808 for implicit rules. Also fixes bug #12091.
2810 * commands.h (set_file_variables): Declare.
2811 * commands.c (set_file_variables): Remove static specifier.
2813 * dep.h (free_dep_chain): Declare.
2814 * misc.c (free_dep_chain): Implement.
2816 * variable.h (variable_expand_for_file): Declare.
2817 * expand.c (variable_expand_for_file): Remove static specifier.
2819 * make.h (strip_whitespace): Declare.
2820 * function.c (strip_whitespace): Remove static specifier.
2822 2005-02-26 Paul D. Smith <psmith@gnu.org>
2824 * main.c (main): Check for ferror() when reading makefiles from stdin.
2825 Apparently some shells in Windows don't close pipes properly and
2828 2005-02-24 Jonathan Grant <jg@jguk.org>
2830 * configure.in: Add MinGW configuration options, and extra w32 code
2832 * Makefile.am: Add MinGW configuration options, and extra w32 code
2834 * main.c: Determine correct program string (after last \ without .exe).
2835 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
2837 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
2838 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
2839 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
2840 environment support.
2842 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
2844 * function.c (func_shell): When initializing error_prefix, check
2845 that reading file name is not null. This fixes long-standing
2846 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2848 2005-02-09 Paul D. Smith <psmith@gnu.org>
2850 * maintMakefile: Update the CVS download URL to simplify them.
2851 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
2852 downloading the .texi files from Savannah now.
2854 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
2856 * main.c (handle_non_switch_argument): Only add variables to
2857 command_variables if they're not already there: duplicate settings
2858 waste space and can be confusing to read.
2860 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
2861 this header is never included by non-WINDOWS32 code, and it
2862 requires <config.h> to define which isn't always included first.
2864 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
2865 testing MINGW32 versions.
2867 * main.c (log_working_directory): flush stdout to be sure the WD
2868 change is printed before any stderr messages show up.
2870 2005-02-01 Paul D. Smith <psmith@gnu.org>
2872 * maintMakefile (po_repo): Update the GNU translation site URL.
2874 2004-12-01 Paul D. Smith <psmith@gnu.org>
2876 * main.c (main): Change char* env_shell to struct variable shell_var.
2877 * variable.c (target_environment): Use new shell_var.
2879 2004-11-30 Paul D. Smith <psmith@gnu.org>
2881 * configure.in: The old way we avoided creating build.sh from
2882 build.sh.in before build.sh.in exists doesn't work anymore; we
2883 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
2884 the help!). This also keeps automake from complaining.
2885 * Makefile.am (README): Add a dummy target so automake won't
2886 complain that this file doesn't exist when we checkout from CVS.
2887 * maintMakefile (.dep_segment): Rewrite this rule since newer
2888 versions of automake don't provide DEP_FILES.
2890 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
2892 Implementation of `realpath' and `abspath' built-in functions.
2894 * configure.in: Check for realpath.
2895 * function.c (abspath): Return an absolute file name that does
2896 not contain any `.' or `..' components, nor repeated `/'.
2897 * function.c (func_abspath): For each name call abspath.
2898 * function.c (func_realpath): For each name call realpath
2899 from libc or delegate to abspath if realpath is not available.
2900 * doc/make.texi (Functions for File Names): Document new functions.
2901 * doc/make.texi (Quick Reference): Ditto.
2903 2004-11-28 Paul D. Smith <psmith@gnu.org>
2905 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
2906 arguments. Fixes bug #10252.
2908 Fix for bug #1276: Handle SHELL according to POSIX requirements.
2910 * main.c (main): Set SHELL to v_noexport by default. Remember the
2911 original environment setting of SHELL in the env_shell variable.
2912 * main.h: Export new env_shell variable.
2913 * variable.c (target_environment): If we find a v_noexport
2914 variable for SHELL, add a SHELL variable with the env_shell value.
2915 * doc/make.texi (Quick Reference): Document the POSIX behavior.
2916 * doc/make.texi (Variables/Recursion): Ditto.
2918 2004-11-28 Paul D. Smith <psmith@gnu.org>
2920 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
2921 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
2922 Patch by Alessandro Vesely.
2924 2004-11-12 Paul D. Smith <psmith@gnu.org>
2926 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
2927 the command line if it's inside a string.
2928 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2930 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
2932 * function.c (func_lastword): New function: return last word
2933 from the list of words.
2934 * doc/make.texi: Document $(lastword ). Fix broken links in
2935 Quick Reference section.
2937 2004-10-06 Paul D. Smith <psmith@gnu.org>
2939 Apply patch from Alessandro Vesely, provided with bug # 9748.
2940 Fix use of tmpnam() to work with Borland C.
2942 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
2943 construction of a temporary filename, and call new function
2944 create_batch_filename().
2945 (create_batch_filename) [WINDOWS32]: New function to create a
2948 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
2950 * read.c (record_target_var): Expand simple pattern-specific
2952 * variable.c (initialize_file_variables): Do not expand simple
2953 pattern-specific variable.
2955 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
2957 * remake.c (update_file_1): When rebuilding makefiles inherit
2958 dontcare flag from a target that triggered update.
2960 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
2962 * variable.c (initialize_file_variables): Mark pattern-specific
2963 variable as a per-target and copy export status.
2965 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
2967 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
2969 * implicit.c (pattern_search): When considering an implicit rule's
2970 prerequisite check that it is actually a target rather then
2971 just an entry in the file hashtable.
2973 2004-09-21 Paul D. Smith <psmith@gnu.org>
2975 * read.c (readstring): Fix some logic errors in backslash handling.
2976 (eval): Remove some unnecessary processing in buffer handling.
2977 (record_target_var): Assert that parse_variable_definition() succeeded.
2978 Reported by: Markus Mauhart <qwe123@chello.at>.
2980 * misc.c: Removed the sindex() function. All instances of this
2981 function were trivially replaceable by the standard strstr()
2982 function, and that function will always have better (or certainly
2983 no worse) performance than the very simple-minded algorithm
2984 sindex() used. This can matter with complex makefiles.
2985 * make.h: Remove the prototype for sindex().
2986 * function.c (subst_expand): Convert sindex() call to strstr().
2987 This means we no longer need to track the TLEN value so remove that.
2988 (func_findstring): Convert sindex() to strstr().
2989 * commands.c (chop_commands): Convert sindex() calls to strstr().
2990 Suggested by: Markus Mauhart <qwe123@chello.at>.
2992 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
2993 idea behind Savannah Patch #3144 from david.baird@homemail.com.
2994 If SHELL is set to CMD.EXE then assume it's batch-mode and
2995 non-unixy. I wrote the code differently from the patch, though,
2996 to make it safer. This also resolves bug #9174.
2998 2004-09-20 Paul D. Smith <psmith@gnu.org>
3000 * expand.c (variable_expand_string): Modify to invoke
3001 patsubst_expand() instead of subst_expand(); the latter didn't
3002 handle suffix patterns correctly.
3003 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
3004 was used only from variable_expand_string() and is no longer used
3006 (func_subst): Ditto, on call to subst_expand().
3007 (patsubst_expand): Require the percent pointers to point to the
3008 character after the %, not to the % itself.
3009 * read.c (record_files): New call criteria for patsubst_expand().
3010 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
3011 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
3013 2004-09-19 Paul D. Smith <psmith@gnu.org>
3015 * function.c (subst_expand): Fix a check in by_word: look for a
3016 previous blank if we're beyond the beginning of the string, not
3017 the beginning of the word.
3018 Bugs reported by Markus Mauhart <qwe123@chello.at>.
3020 2004-05-16 Paul D. Smith <psmith@gnu.org>
3022 * remake.c (update_goal_chain): Change the argument specifying
3023 whether we're rebuilding makefiles to be a global variable,
3024 REBUILDING_MAKEFILES.
3025 (complain): Extract the code that complains about no rules to make
3026 a target into a separate function.
3027 (update_file_1): If we tried to rebuild a file during the makefile
3028 rebuild phase and it was dontcare, then no message was printed.
3029 If we then try to build the same file during the normal build,
3030 print a message this time.
3031 (remake_file): Don't complain about un-remake-able files when
3032 we're rebuilding makefiles.
3034 2004-05-11 Paul D. Smith <psmith@gnu.org>
3036 * job.c (construct_command_argv_internal): OS/2 patches from
3037 Andreas Buening <andreas.buening@nexgo.de>.
3039 2004-05-10 Paul D. Smith <psmith@gnu.org>
3041 * remake.c (update_file): Don't walk the double-colon chain unless
3042 this is a double-colon rule. Fix suggested by Boris Kolpackov
3043 <boris@kolpackov.net>.
3045 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
3046 * readme.vms: New section describing OpenVMS support and issues.
3047 * default.c (default_variables): Add support for IA64.
3048 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
3049 without some privilege aborts make with the error
3050 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
3051 pressing Ctrl+Y and the input device is no terminal. The change
3052 catches this error and just continues.
3054 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
3056 2004-04-25 Paul D. Smith <psmith@gnu.org>
3058 * commands.c (set_file_variables): Set $< properly in the face of
3059 order-only prerequisites.
3060 Patch from Boris Kolpackov <boris@kolpackov.net>
3062 2004-04-21 Bob Byrnes <byrnes@curl.com>
3064 * main.c (main): Notice failures to remake makefiles.
3066 2004-03-28 Paul D. Smith <psmith@gnu.org>
3068 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
3070 * job.c: No default shell for RISC OS.
3071 (load_too_high): Hard-code the return to 1.
3072 (construct_command_argv_internal): No sh_chars or sh_cmds.
3073 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
3075 2004-03-20 Paul D. Smith <psmith@gnu.org>
3077 * variable.c (do_variable_definition): Don't append from the
3078 global set if a previous non-appending target-specific variable
3079 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
3082 * expand.c (reference_variable): Don't give up on variables with
3083 no value that have the target-specific append flag set: they might
3084 have a value after all. Reported by Oliver Schmidt
3085 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
3086 <nikulin@dx1cmd.inp.nsk.su>.
3088 * rule.c (count_implicit_rule_limits): Don't delete patterns which
3089 refer to absolute pathnames in directories that don't exist: some
3090 portion of the makefile could create those directories before we
3091 match the pattern. Fixes bugs #775 and #108.
3093 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
3095 * main.c (main): Free makefile_mtimes if we have any.
3096 * README.W32.template: Update documentation for the current status
3097 of the MS-Windows port.
3098 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
3099 environment variable is sometimes already defined which causes the
3101 * main.c (debug_signal_handler): Only define this function if
3102 SIGUSR1 is available.
3104 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
3106 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
3107 * README.OS2.template: Documentation updates.
3108 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
3109 link line for safety.
3110 * maintMakefile (build.sh.in): Remove an extraneous ")".
3111 * job.c (child_execute_job): Close saved FDs.
3112 * job.c (exec_command) [OS/2]: exec_command(): If the command
3113 can't be exec'ed and if the shell is not Unix-sh, then try again
3114 with argv = { "cmd", "/c", ... }. Normally, this code is never
3115 reached for the cmd shell unless the command really doesn't exist.
3116 (construct_command_argv_internal) [OS/2]: The code for cmd
3117 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
3118 The CMD builtin commands are case insensitive so use strcasecmp().
3120 2004-03-19 Paul D. Smith <psmith@gnu.org>
3122 * read.c (do_define): Re-order line counter increment so the count
3123 is accurate (we were losing one line per define). Reported by
3124 Dave Yost <Dave@Yost.com>.
3126 2004-03-06 Paul D. Smith <psmith@gnu.org>
3128 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
3130 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
3131 * misc.c (message,error,fatal): Ditto.
3132 * configh.dos.template: Define HAVE_ANSI_COMPILER.
3133 * config.h.W32.template: Ditto.
3134 * config.h-vms.template: Ditto.
3135 * config.ami.template: Ditto.
3137 2004-03-04 Paul D. Smith <psmith@gnu.org>
3139 * README.template: Add a note about broken /bin/sh on SunOS
3140 4.1.3_U1 & 4.1.4. Fix up Savannah links.
3142 * misc.c (message, error, fatal): Don't use "..." if we're using
3143 varargs. ansi2knr should handle this but it doesn't work: it
3144 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
3145 done. On many systems (SunOS for example) va_dcl is a #define.
3146 So, force the use of the non-"..." version on pre-ANSI compilers.
3148 * maintMakefile (sign-dist): Create some rules to help automate
3149 the new GNU ftp upload method.
3151 2004-02-24 Paul D. Smith <psmith@gnu.org>
3153 * config.h.W32.template: Add HAVE_STDARG_H
3154 * config.h-vms.template: Ditto.
3155 * config.ami.template: Ditto.
3157 2004-02-23 Jonathan Grant <jg-make@jguk.org>
3159 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
3160 * build_w32.bat: Remove extra "+".
3162 2004-02-23 Paul D. Smith <psmith@gnu.org>
3164 * make.h: Create an UNUSED macro to mark unused parameters.
3165 * (many): Clean up warnings by applying UNUSED, fixing
3166 signed/unsigned incompatibilities, etc.
3168 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
3170 * filedef.h: Name the command_state enumeration.
3171 * file.c (set_command_state): Use the enumeration in the function
3174 * configure.in: Explicitly set SET_MAKE to empty, to disable
3175 MAKE=make even when no make already exists. Fix bug #3823.
3177 2004-02-22 Paul D. Smith <psmith@gnu.org>
3179 * maintMakefile: Perl script to clean up all non-CVS files. Use
3180 it on all the subdirectories for the cvs-clean target.
3182 * main.c (decode_switches): Require non-empty strings for all our
3183 string command-line options. Fixes Debian bug # 164165.
3185 * configure.in: Check for stdarg.h and varargs.h.
3186 * make.h (USE_VARIADIC): Set this if we can use variadic functions
3187 for printing messages.
3188 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
3193 A number of patches for OS/2 support from Andreas Buening
3194 <andreas.buening@nexgo.de>:
3196 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
3197 disable the SIGCHLD handler.
3198 (reap_children) [OS/2]: Remove special handling of job_rfd.
3199 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
3200 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
3201 * main.c (main) [OS/2]: Special handling for paths in OS/2.
3202 * configure.in [OS/2]: Force SA_RESTART for OS/2.
3203 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
3206 2004-02-21 Paul D. Smith <psmith@gnu.org>
3208 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
3209 <mail@kristov.de> reports that if process_begin() fails we don't
3210 handle the error condition correctly in all cases.
3211 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
3212 to have a newline on the message.
3214 * job.c (construct_command_argv_internal): Add "test" to UNIX
3215 sh_cmds[]. Fixes Savannah bug # 7606.
3217 2004-02-04 Paul D. Smith <psmith@gnu.org>
3219 * job.c (vms_handle_apos) [VMS]: Fix various string handling
3220 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
3221 Hartmut Becker <Hartmut.Becker@hp.com>.
3223 2004-01-21 Paul D. Smith <psmith@gnu.org>
3225 * job.c (load_too_high): Implement an algorithm to control the
3226 "thundering herd" problem when using -l to control job creation
3227 via the load average. The system only recomputes the load once a
3228 second but we can start many jobs in a second. To solve this we
3229 keep track of the number of jobs started in the last second and
3230 apply a weight to try to guess what a correct load would be.
3231 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
3232 Also fixes bug #4693.
3233 (reap_children): Decrease the job count for this second.
3234 (start_job_command): Increase the job count for this second.
3236 * read.c (conditional_line): Expand the text after ifn?def before
3237 checking to see if it's a single word. Fixes bug #7257.
3239 2004-01-09 Paul D. Smith <psmith@gnu.org>
3241 * file.c (print_file): Recurse to print all targets in
3242 double-colon rules. Fixes bug #4518, reported (with patch) by
3243 Andrew Chatham <chatham@google.com>.
3245 2004-01-07 Paul D. Smith <psmith@gnu.org>
3247 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
3248 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
3249 AC_FUNC_SETVBUF_REVERSED.
3251 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
3252 (MAKE Variable): Fix Savannah bug #4898.
3254 * job.c (construct_command_argv_internal): Add "!" to the list of
3255 shell escape chars. POSIX sh allows it to appear before a
3256 command, to negate the exit code. Fixes bug #6404.
3258 * implicit.c (pattern_search): When matching an implicit rule,
3259 remember which dependencies have the ignore_mtime flag set.
3260 Original fix provided in Savannah patch #2349, by Benoit
3261 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
3263 2003-11-22 Paul D. Smith <psmith@gnu.org>
3265 * README.W32.template (Outputs): Clarification on -j with
3266 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
3269 2003-11-02 Paul D. Smith <psmith@gnu.org>
3271 * function.c (func_if): Strip all the trailing whitespace from the
3272 condition, then don't expand it. Fixed bug # 5798.
3274 * expand.c (recursively_expand_for_file): If we're expanding a
3275 variable with no file context, then use the variable's context.
3278 2003-10-21 Paul D. Smith <psmith@gnu.org>
3280 * main.c (log_working_directory): Add newlines to printf()s.
3282 * README.cvs: Add a note to ignore warnings during autoreconf.
3284 * maintMakefile (po_repo): Set a new URL for PO file updates.
3285 (get-config/config.guess get-config/config.sub): Get these files
3286 from the Savannah config project instead of ftp.gnu.org.
3288 2003-10-05 Paul Eggert <eggert@twinsun.com>
3290 * main.c (main): Avoid potential subscript error if environ has
3293 2003-08-22 Paul D. Smith <psmith@gnu.org>
3295 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
3296 systems which don't yet implement the C89 standard :-/.
3298 2003-07-18 Paul D. Smith <psmith@gnu.org>
3300 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
3301 [WINDOWS32]: Initialize hash.
3303 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
3305 * dir.c (read_dirstream): Provide a workaround for broken versions of
3306 the MinGW dirent structure.
3308 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3310 * w32/include/dirent.h: Add __MINGW32__ filter.
3312 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3314 * make.h: Add global declaration of *make_host.
3315 * main.c (print_usage): Remove local declaration of *make_host.
3316 (print_version): Display "This program built for ..." after Copyright
3319 2003-05-30 Earnie Boyd <earnie@users.sf.net>
3321 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
3322 execution of "makeinfo --html make.texi".
3324 2003-04-30 Paul D. Smith <psmith@gnu.org>
3326 * build.template: Make some changes to maybe allow this script to
3327 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
3329 * README.OS2.template: New file for OS/2 support. Original
3330 contributed by Andreas Buening.
3331 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
3334 2003-04-19 Paul D. Smith <psmith@gnu.org>
3336 Fix bug #1405: allow a target to match multiple pattern-specific
3339 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
3340 variable.c, where they've always belonged.
3341 * rule.h: Move the prototypes and struct pattern_var as well.
3342 * variable.c (initialize_file_variables): Invoke
3343 lookup_pattern_var() in a loop, until no more matches are found.
3344 If a match is found, create a new variable set for the target's
3345 pattern variables. Then merge the contents of each matching
3346 pattern variable set into the target's pattern variable set.
3347 (lookup_pattern_var): Change this function to be usable
3348 in a loop. It takes a starting position: if NULL, start at the
3349 beginning; if non-NULL, start with the pattern variable after that
3350 position, and return the next matching pattern.
3351 (create_pattern_var): Create a unique instance of
3352 pattern-specific variables for every definition in the makefile.
3353 Don't combine the same pattern together. This allows us to
3354 process the variable handling properly even when the same pattern
3355 is used multiple times.
3356 (parse_variable_definition): New function: break out the parsing
3357 of a variable definition line from try_variable_definition.
3358 (try_variable_definition): Call parse_variable_definition to
3360 (print_variable_data_base): Print out pattern-specific variables.
3361 * variable.h (struct variable): Remember when a variable is
3362 conditional. Also remember its flavor.
3363 (struct pattern_var): Instead of keeping a variable set, we just
3364 keep a single variable for each pattern.
3365 * read.c (record_target_var): Each pattern variable contains only a
3366 single variable, not a set, so create it properly.
3367 * doc/make.texi (Pattern-specific): Document the new behavior.
3369 2003-04-17 Paul D. Smith <psmith@gnu.org>
3371 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
3372 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
3373 file/directory naming rules for VMS so I can't tell whether this
3376 2003-04-09 Paul D. Smith <psmith@gnu.org>
3378 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
3379 DOS-style pathnames: backslash separators and drive specifiers.
3381 2003-03-28 Paul D. Smith <psmith@gnu.org>
3383 * file.c (snap_deps): If .SECONDARY with no targets is given, set
3384 the intermediate flag on all targets. Fixes bug #2515.
3386 2003-03-24 Paul D. Smith <psmith@gnu.org>
3388 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
3389 Upgrade to autoconf 2.57 and automake 1.7.3.
3391 * job.c: More OS/2 changes from Andreas Buening.
3393 * file.c (print_file): Fix variable initialization.
3396 * remake.c (notice_finished_file):
3398 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
3399 some calls (like readdir()) return NULL in valid situations
3400 without resetting errno. Fixes bug #2846.
3402 2003-02-25 Paul D. Smith <psmith@gnu.org>
3404 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
3406 * job.c (_is_unixy_shell) [OS/2]: New function.
3407 Set default shell to /bin/sh.
3408 (reap_children): Close the job_rfd pipe here since we don't use a
3410 (set_child_handler_action_flags): define this to empty on OS/2.
3411 (start_job_command): Close the jobserver pipe and use
3412 child_execute_job() instead of fork/exec.
3413 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
3414 rather than exec'ing, then reconfigure stdin/stdout.
3415 (exec_command): Rewrite to use spawn instead of exec. Return the
3418 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
3419 in DOS. Handle the TEMP environment variable as in DOS. Don't
3420 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
3421 use -j in DOS mode. Use child_execute_job() instead of
3424 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
3427 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
3428 prototypes that return values.
3430 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
3432 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
3433 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
3435 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
3438 2003-02-24 Paul D. Smith <psmith@gnu.org>
3440 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
3441 * job.c (child_execute_job) [VMS]: New code for handling spawn().
3442 (child_execute_job) [VMS]: Handle error status properly.
3443 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
3445 * function.c (func_shell): Use EINTRLOOP() while reading from the
3446 subshell pipe (Fixes bug #2502).
3447 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
3449 * main.c (main): Ditto.
3451 2003-01-30 Paul D. Smith <psmith@gnu.org>
3453 * read.c (eval): eval() was not fully reentrant, because the
3454 collapsed buffer was static. Change it to be an automatic
3455 variable so that eval() can be invoked recursively.
3457 (eval): Apply patch # 1022: fix memory reference error on long
3458 target-specific variable lines.
3459 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
3461 * function.c (check_numeric): Combine the is_numeric() function
3462 into this function, since it's only called from one place.
3463 Constify this function. Have it print the incorrect string in the
3464 error message. Fixes bug #2407.
3465 (strip_whitespace): Constify.
3466 (func_if): Constify.
3467 * expand.c (expand_argument): Constify.
3469 2003-01-29 Paul D. Smith <psmith@gnu.org>
3471 Fix bug # 2169, also reported by other people on various systems.
3473 * make.h: Some systems, such as Solaris and PTX, do not fully
3474 implement POSIX-compliant SA_RESTART functionality; important
3475 system calls like stat() and readdir() can still fail with EINTR
3476 even if SA_RESTART has been set on the signal handler. So,
3477 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
3478 EINTR for system calls which return -1 or 0 (NULL), respectively,
3480 Also, remove the old atomic_stat()/atomic_readdir() and
3481 HAVE_BROKEN_RESTART handling.
3483 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
3485 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
3486 * remake.c (touch_file): Ditto.
3488 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
3489 * read.c (construct_include_path): Ditto.
3490 * remake.c (name_mtime): Ditto.
3491 * vpath.c (selective_vpath_search): Ditto.
3492 * dir.c (find_directory): Ditto.
3493 (local_stat): Ditto.
3494 (find_directory): Use ENULLLOOP() to wrap opendir().
3495 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
3497 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
3498 atomic_readdir() handling.
3500 2003-01-22 Paul D. Smith <psmith@gnu.org>
3502 * function.c (func_call): Fix Bug #1744. If we're inside a
3503 recursive invocation of $(call ...), mask any of the outer
3504 invocation's arguments that aren't used by this one, so that this
3505 invocation doesn't "inherit" them accidentally.
3507 2002-12-05 Paul D. Smith <psmith@gnu.org>
3509 * function.c (subst_expand): Valery Khamenia reported a
3510 pathological performance hit when doing substitutions on very
3511 large values with lots of words: turns out we were invoking
3512 strlen() a ridiculous number of times. Instead of having each
3513 call to sindex() call strlen() again, keep track of how much of
3514 the text we've seen and pass the length to sindex().
3516 2002-11-19 Paul D. Smith <psmith@gnu.org>
3518 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
3521 2002-11-16 Paul D. Smith <psmith@gnu.org>
3523 * NMakefile.template (OBJS): Add hash.c object file.
3524 * SMakefile.template (srcs): Ditto.
3525 * Makefile.ami (objs): Ditto.
3526 * build_w32.bat: Ditto.
3528 * Makefile.DOS.template: Remove extra dependencies.
3530 2002-10-25 Paul D. Smith <psmith@gnu.org>
3532 * expand.c (install_variable_buffer): New function. Install a new
3533 variable_buffer context and return the previous one.
3534 (restore_variable_buffer): New function. Free the current
3535 variable_buffer context and put a previously saved one back.
3536 * variable.h: Prototypes for {install,restore}_variable_buffer.
3537 * function.c (func_eval): Push a new variable_buffer context
3538 before we eval, then restore the old one when we're done.
3541 * read.c (install_conditionals): New function. Install a new
3542 conditional context and return the previous one.
3543 (restore_conditionals): New function. Free the current
3544 conditional context and put a previously saved one back.
3545 (eval): Use the {install,restore}_conditionals for "include"
3547 (eval_buffer): Use {install,restore}_conditionals to preserve the
3548 present conditional state before we evaluate the buffer.
3551 * doc/make.texi (Quick Reference): Add references to $(eval ...)
3553 (Recursion): Add a variable index entry for CURDIR.
3555 * README.cvs: Update to appropriate versions.
3556 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
3557 don't need to copy loadavg.c: automake is smart enough to create
3558 it for me. Still have a bug in automake related to ansi2knr tho.
3560 2002-10-14 Paul D. Smith <psmith@gnu.org>
3562 * remake.c (notice_finished_file): Only touch targets if they have
3563 at least one command (as per POSIX). Resolve Bug #1418.
3565 * *.c: Convert to using ANSI C-style function definitions.
3566 * Makefile.am: Enable the ansi2knr feature of automake.
3567 * configure.in: ditto.
3569 2002-10-13 Paul D. Smith <psmith@gnu.org>
3571 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
3572 for automatic variable values like $^, etc. In the case of very
3573 large lists of prerequisites this causes problems. Instead reuse
3574 a static buffer (resizeable) for each variable.
3576 * read.c (eval): Fix Bug #1391: allow "export" keyword in
3577 target-specific variable definitions. Check for it and set an
3579 (record_target_var): Set the export field to v_export if the
3580 "exported" flag is set.
3581 * doc/make.texi (Target-specific): Document the ability to use
3584 * doc/make.texi: Change the name of the section on automatic
3585 variables from "Automatic" to "Automatic Variables". Added text
3586 clarifying the scope of automatic variables.
3588 2002-10-04 Paul D. Smith <psmith@gnu.org>
3590 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
3592 (record_files): Ditto.
3594 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
3595 the search for the '=' to only within the enclosing parens.
3597 2002-10-03 Paul D. Smith <psmith@gnu.org>
3599 Version 3.80 released.
3601 * dir.c: Change hash functions to use K&R function definition style.
3602 * function.c: Ditto.
3604 * variable.c: Ditto.
3606 Update to automake 1.7.
3608 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
3609 (pdf): Remove this target as automake now provides one.
3611 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
3613 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
3615 * makefile.com: Updates for GNU make 3.80.
3616 * makefile.vms: Ditto.
3618 2002-09-23 Paul D. Smith <psmith@gnu.org>
3620 * read.c (enum make_word_type): Remove w_comment.
3621 (get_next_mword): Don't treat comment characters as special; where
3622 this function is used we will never see a comment (it's stripped
3623 before we get here) and treating comments specially means that
3624 targets like "foo\#bar" aren't handled properly.
3626 2002-09-18 Paul D. Smith <psmith@gnu.org>
3628 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
3630 * read.c (eval): Expansion of arguments to export/unexport was
3631 ignoring all arguments after the first one. Change the algorithm
3632 to expand the whole line once, then parse the results.
3634 2002-09-17 Paul D. Smith <psmith@gnu.org>
3636 Fix Bug #940 (plus another bug I found while looking at this):
3638 * read.c (record_target_var): enter_file() will add a new entry if
3639 it's a double-colon target: we don't want to do that in this
3640 situation. Invoke lookup_file() and only enter_file() if it does
3641 not already exist. If the file we get back is a double-colon then
3642 add this variable to the "root" double-colon target.
3644 * variable.c (initialize_file_variables): If this file is a
3645 double-colon target but is not the "root" target, then initialize
3646 the root and make the root's variable list the parent of our
3649 2002-09-13 Paul D. Smith <psmith@gnu.org>
3651 * doc/make.texi (MAKE Variable): Add some indexing for "+".
3653 * hash.c (round_up_2): Get rid of a warning.
3655 2002-09-12 Paul D. Smith <psmith@gnu.org>
3657 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
3658 so it doesn't complain about getloadavg.c.
3660 * commands.c (set_file_variables): Make sure we always alloca() at
3661 least 1 character for the value of $? (for '\0').
3663 2002-09-11 Paul D. Smith <psmith@gnu.org>
3665 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
3666 macro to use RESULT instead of the incorrect _RESULT_.
3668 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
3669 and atomic_readdir(). We need to #include dirent.h to get this to
3671 * misc.c (atomic_readdir): Fix typos.
3673 2002-09-10 Paul D. Smith <psmith@gnu.org>
3675 * read.c (eval): Expand variable lists given to export and
3676 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
3677 (conditional_line): Ditto for "ifdef". Fixes bug #103.
3679 * doc/make.texi (Variables/Recursion): Document this.
3680 (Conditional Syntax): And here.
3682 2002-09-09 Paul D. Smith <psmith@gnu.org>
3684 * configure.in: Check for memmove().
3686 2002-09-07 Paul D. Smith <psmith@gnu.org>
3688 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
3689 Michael Sterrett <msterret@coat.com> reports that while it has
3690 SA_RESTART, it does not work properly.
3692 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
3693 that invokes stat() and loops to do it again if it returns EINTR.
3694 (atomic_readdir): Ditto, with readdir().
3696 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
3697 and readdir() to atomic_stat() and atomic_readdir().
3699 2002-09-04 Paul D. Smith <psmith@gnu.org>
3701 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
3702 reports that GNU make sometimes doesn't recognize that targets can
3703 be made, when directories can be created as prerequisites. He
3704 reports that changing the order of predicates in the DEP->changed
3705 flag test so that lookup_file() is always performed, solves this
3708 2002-08-08 Paul D. Smith <psmith@gnu.org>
3710 * configure.in: Require a newer version of gettext.
3712 * misc.c (perror_with_name): Translate the format string (for
3713 right-to-left language support).
3714 (pfatal_with_name): Ditto.
3716 * main.c: Create a static array of strings to store the usage
3717 text. This is done to facilitate translations.
3718 (struct command_switch): Remove argdesc and description fields.
3719 (switches): Remove values for obsolete fields.
3720 (print_usage): Print each element of the usage array.
3722 * hash.c: Change function definitions to be K&R style.
3724 2002-08-02 Paul D. Smith <psmith@gnu.org>
3726 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
3727 this one because it's too hard to get right. We'll look at it for
3729 * main.c (main): Don't create the .TARGETS variable.
3730 * variable.c (handle_special_var): Don't handle .TARGETS.
3732 2002-08-01 Paul D. Smith <psmith@gnu.org>
3734 * main.c (switches): Add a new option, -B (--always-make). If
3735 specified, make will rebuild all targets that it encounters even
3736 if they don't appear to be out of date.
3737 (always_make_flag): New flag.
3738 * make.h: Extern always_make_flag.
3739 * remake.c (update_file_1): Check always_make_flag; if it's set we
3740 will always rebuild any target we can, even if none of its
3741 prerequisites are newer.
3744 * doc/make.texi (Shell Function): Make it clear that make
3745 variables marked as "export" are not passed to instances of the
3748 Add new introspection variable .VARIABLES and .TARGETS.
3750 * variable.c (handle_special_var): New function. If the variable
3751 reference passed in is "special" (.VARIABLES or .TARGETS),
3752 calculate the new value if necessary. .VARIABLES is handled here:
3753 walk through the hash of defined variables and construct a value
3754 which is a list of the names. .TARGETS is handled by
3755 build_target_list().
3756 (lookup_variable): Invoke handle_special_var().
3757 * file.c (build_target_list): Walk through the hask of known files
3758 and construct a list of the names of all the ones marked as
3760 * main.c (main): Initialize them to empty (and as simple variables).
3761 * doc/make.texi (Special Variables): Document them.
3762 * NEWS: Mention them.
3764 * variable.h (struct variable): Add a new flag "exportable" which
3765 is true if the variable name is valid for export.
3766 * variable.c (define_variable_in_set): Set "exportable" when a new
3767 variable is defined.
3768 (target_environment): Use the "exportable" flag instead of
3769 re-checking the name here... an efficiency improvement.
3771 2002-07-31 Paul D. Smith <psmith@gnu.org>
3773 * config.h-vms.template: Updates to build on VMS. Thanks to
3774 Brian_Benning@aksteel.com for helping verify the build.
3775 * makefile.com: Build the new hash.c file.
3776 * hash.h: Use strcpmi(), not stricmp(), in the
3777 HAVE_CASE_INSENSITIVE_FS case.
3779 2002-07-30 Paul D. Smith <psmith@gnu.org>
3781 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
3782 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
3783 Reported by <Brian_Benning@aksteel.com>.
3785 2002-07-10 Paul D. Smith <psmith@gnu.org>
3787 * variable.c (pop_variable_scope): Remove variable made unused by
3788 new hash infrastructure.
3789 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
3790 comparisons as well as name comparisons.
3791 * variable.h: Add a prototype for new hash_init_function_table().
3792 * file.c (lookup_file): Remove variables made unused by new hash
3794 * dir.c (directory_contents_hash_2): Missing return of hash value.
3795 (dir_contents_file_exists_p): Remove variables made unused by new
3796 hash infrastructure.
3799 Installed Greg McGary's integration of the hash functions from the
3800 GNU id-utils package:
3802 2002-07-10 Greg McGary <greg@mcgary.org>
3804 * scripts/functions/filter-out: Add literals to to the
3805 pattern space in order to add complexity, and trigger
3806 use of an internal hash table. Fix documentation strings.
3807 * scripts/targets/INTERMEDIATE: Reverse order of files
3808 passed to expected `rm' command.
3810 2002-07-10 Greg McGary <greg@mcgary.org>

3902 2002-07-10 Paul D. Smith <psmith@gnu.org>
3904 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
3905 prerequisite list. A real SysV make will expand the entire
3906 prerequisites list _twice_: we don't do that as it's a big
3907 backward-compatibility problem. We only replace those specific
3910 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
3911 references left in the list of prerequisites. Check for .POSIX as
3912 we record targets, so we can disable non-POSIX behavior while
3913 reading makefiles as well as running them.
3914 (eval): Check the prerequisite list to see if we have anything
3915 that looks like a SysV prerequisite variable reference.
3917 2002-07-09 Paul D. Smith <psmith@gnu.org>
3919 * doc/make.texi (Prerequisite Types): Add a new section describing
3920 order-only prerequisites.
3922 * read.c (uniquize_deps): If we have the same file as both a
3923 normal and order-only prereq, get rid of the order-only prereq,
3924 since the normal one supersedes it.
3926 2002-07-08 Paul D. Smith <psmith@gnu.org>
3928 * AUTHORS: Added Greg McGary to the AUTHORS file.
3929 * NEWS: Blurbed order-only prerequisites.
3930 * file.c (print_file): Show order-only deps properly when printing
3933 * maintMakefile: Add "update" targets for wget'ing the latest
3934 versions of various external files. Taken from Makefile.maint in
3937 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
3938 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
3940 2002-07-07 Paul D. Smith <psmith@gnu.org>
3942 * po/*.po: Remove. We'll use wget to retrieve them at release
3945 * variable.c (do_variable_definition) [W32]: On W32 using cmd
3946 rather than a shell you get an exception. Make sure we look up
3947 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
3949 * remake.c (notice_finished_file): Fix handling of -t flag.
3950 Patch provided by Henning Makholm <henning@makholm.net>.
3952 * implicit.c (pattern_search): Some systems apparently run short
3953 of stack space, and using alloca() in this function caused an
3954 overrun. I modified it to use xmalloc() on the two variables
3955 which seemed like they might get large. Fixes Bug #476.
3957 * main.c (print_version): Update copyright notice to conform with
3959 (print_usage): Update help output.
3961 * function.c (func_eval): Create a new make function, $(eval
3962 ...). Expand the arguments, put them into a buffer, then invoke
3963 eval_buffer() on the resulting string.
3964 (func_quote): Create a new function, $(quote VARNAME). Inserts
3965 the value of the variable VARNAME without expanding it any
3968 * read.c (struct ebuffer): Change the linebuffer structure to an
3969 "eval buffer", which can be either a file or a buffer.
3970 (eval_makefile): Move the code in the old read_makefile() which
3971 located a makefile into here: create a struct ebuffer with that
3972 information. Have it invoke the new function eval() with that
3974 (eval_buffer): Create a new function that creates a struct ebuffer
3975 that holds a string buffer instead of a file. Have it invoke
3976 eval() with that ebuffer.
3977 (eval): New function that contains the guts of the old
3978 read_makefile() function: this function parses makefiles. Obtains
3979 data to parse from the provided ebuffer. Some modifications to
3980 make the flow of the function cleaner and clearer. Still could
3981 use some work here...
3982 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
3983 contents of the define/endef variable from the ebuffer.
3984 (readstring): Read the next line from a string-style ebuffer.
3985 (readline): Read the next line from an ebuffer. If it's a string
3986 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
3989 * dep.h (eval_buffer): Prototype eval_buffer();
3991 * variable.c (do_variable_definition): Make sure that all
3992 non-target-specific variables are registered in the global set.
3993 If we're invoked from an $(eval ...) we might be inside a $(call
3994 ...) or other function which has pushed a variable scope; we still
3995 want to define our variables from evaluated makefile code in the
3998 2002-07-03 Greg McGary <greg@mcgary.org>
4000 * dep.h (struct dep) [ignore_mtime]: New member.
4001 [changed]: convert to a bitfield.
4002 * implicit.c (pattern_search): Zero ignore_mtime.
4003 * main.c (main, handle_non_switch_argument): Likewise.
4004 * rule.c (convert_suffix_rule): Likewise.
4005 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
4006 (read_makefile): Parse '|' in prerequisite list.
4007 (uniquize_deps): Consider ignore_mtime when comparing deps.
4008 * remake.c (update_file_1, check_dep): Don't force remake for
4009 dependencies that have d->ignore_mtime.
4010 * commands.c (FILE_LIST_SEPARATOR): New constant.
4011 (set_file_variables): Don't include a
4012 prerequisite in $+, $^ or $? if d->ignore_mtime.
4015 2002-06-18 Paul D. Smith <psmith@gnu.org>
4017 * make.texinfo: Updates for next revision. New date/rev/etc.
4018 Recreate all Info menus. Change license on the manual to the GNU
4019 Free Documentation License. A number of typos.
4020 (Variables Simplify): Don't use "-" before it's defined.
4021 (Automatic Prerequisites): Rewrite the target example to work
4022 properly if the compile fails. Remove incorrect comments about
4023 how "set -e" behaves.
4024 (Text Functions): Move the "word", "wordlist", "words", and
4025 "firstword" functions here, from "File Name Functions".
4026 * make-stds.texi: Update from latest GNU version.
4027 * fdl.texi: (created) Import the latest GNU version.
4029 2002-06-06 Paul D. Smith <psmith@gnu.org>
4031 * variable.c (do_variable_definition): New function: extract the
4032 part of try_variable_definition() that actually sets the value
4033 into a separate function.
4034 (try_variable_definition): Call do_variable_definition() after
4035 parsing the variable definition string.
4036 (define_variable_in_set): Make the name argument const.
4038 * variable.h (enum variable_flavor): Make public.
4039 (do_variable_definition): Create prototype.
4041 * read.c (read_all_makefiles): Create a new built-in variable,
4043 (read_makefile): Add each makefile read in to this variable value.
4045 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
4047 * Makefile.DOS.template: Tweak according to changes in the
4048 distribution. Add back the dependencies of *.o files.
4050 * configh.dos.template: Synchronize with config.h.in.
4052 2002-05-09 Paul D. Smith <psmith@gnu.org>
4054 * file.c (file_timestamp_now): Use K&R function declaration.
4056 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
4057 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
4058 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
4059 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
4060 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
4061 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
4062 nlist.n_name is a pointer rather than an array.
4064 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
4065 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
4066 * configure.in: Use it instead of the old version.
4068 * main.c (main): Prefer setvbuf() to setlinebuf().
4070 2002-05-08 Paul D. Smith <psmith@gnu.org>
4072 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
4073 (loadavg_LDADD): Ditto.
4075 2002-04-29 Paul D. Smith <psmith@gnu.org>
4077 * expand.c (recursively_expand_for_file): Rename
4078 recursively_expand() to recursively_expand_for_file() and provide
4079 an extra argument, struct file. If the argument is provided, set
4080 the variable scope to that of the file before expanding.
4081 * variable.h (recursively_expand): Make this a macro that invokes
4082 recursively_expand_for_file() with a NULL file pointer.
4083 * variable.c (target_environment): Call the renamed function and
4084 provide the current file context.
4085 Fixes Debian bug #144306.
4087 2002-04-28 Paul D. Smith <psmith@gnu.org>
4089 Allow $(call ...) user-defined variables to be self-referencing
4090 without throwing an error. Allows implementation of transitive
4091 closures, among other possibly useful things.
4092 Requested by: Philip Guenther <guenther@sendmail.com>
4094 * variable.h (struct variable): Add a new field: exp_count, and
4095 new macros to hold its size and maximum value.
4096 (warn_undefined): Make this a macro.
4097 * variable.c (define_variable_in_set): Initialize it.
4098 * expand.c (recursively_expand): If we detect recursive expansion
4099 of a variable, check the exp_count field. If it's greater than 0
4100 allow the recursion and decrement the count.
4101 (warn_undefined): Remove this (now a macro in variable.h).
4102 * function.c (func_call): Before we expand the user-defined
4103 function, modify its exp_count field to contain the maximum
4104 number of recursive calls we'll allow. After the call, reset it
4107 2002-04-21 Paul D. Smith <psmith@gnu.org>
4109 Modified to use latest autoconf (2.53), automake (1.6.1), and
4110 gettext (0.11.1). We're using gettext's new "external" support,
4111 to avoid including libintl source with GNU make.
4113 * README.cvs: New file. Explain how to build GNU make from CVS.
4115 * configure.in: Modify checking for the system glob library.
4116 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
4117 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
4118 etc. will manage it correctly). Set an automake conditional
4119 USE_LOCAL_GLOB to decide whether to compile the glob library.
4121 * getloadavg.c (main): Include make.h in the "TEST" program to
4124 * Makefile.am: Remove special rules for loadavg. Replace them
4125 with Automake capabilities for building extra programs.
4127 * signame.c: This file does nothing if the system provide
4128 strsignal(). If not, it implements strsignal(). If the system
4129 doesn't define sys_siglist, then we make our own; otherwise we use
4131 * signame.h: Removed.
4133 * main.c (main): No need to invoke signame_init(). Update copyright.
4135 * ABOUT-NLS: Removed.
4136 * gettext.c: Removed.
4137 * gettext.h: Get a simplified copy from the gettext package.
4139 * i18n/*.po: Moved to po/.
4142 * config/*: Created. Contains package configuration helper files.
4143 * config.guess, config.sub: Moved to config directory.
4145 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
4146 Rework to use new-style autoconf features. Use the "external"
4147 mode for gettext. Make the build.sh config file conditional on
4148 whether build.sh.in exists, to avoid autoconf errors.
4149 * acinclude.m4: Removed almost all macros as being obsolete.
4150 Rewrote remaining macros to use AC_DEFINE.
4151 * acconfig.h: Removed.
4153 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
4154 conditional to handle customs support. Remove special handling
4157 2002-04-20 Paul D. Smith <psmith@gnu.org>
4159 * function.c (func_call): Don't mark the argument variables $1,
4160 etc. as recursive. They've already been fully expanded so
4161 there's no need to do it again, and doing so strips escaped $'s.
4162 Reported by Sebastian Glita <glseba@yahoo.com>.
4164 * remake.c (notice_finished_file): Walk through double-colon
4165 entries via the prev field, not the next field!
4166 Reported by Greg McGary <greg@mcgary.org>.
4168 * main.c (main): If the user specifies -q and asks for a specific
4169 target which is a makefile, we got an assert. In that case it
4170 turns out we should continue normally instead.
4172 * i18n/de.po, i18n/fr.po: Installed an updated translation.
4174 * i18n/he.po: Installed a new translation.
4176 2002-01-07 Paul D. Smith <psmith@gnu.org>
4178 * i18n/es.po, i18n/ru.po: Installed an updated translation.
4180 2001-12-04 Paul D. Smith <psmith@gnu.org>
4182 * i18n/ja.po: Installed an updated translation.
4184 2001-09-06 Paul Eggert <eggert@twinsun.com>
4186 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
4187 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
4189 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
4191 (main): Get rid of any avoidable limit on stack size.
4193 2001-09-04 Paul D. Smith <psmith@gnu.org>
4195 * i18n/da.po: Installed an updated translation.
4197 2001-08-03 Paul D. Smith <psmith@gnu.org>
4199 * i18n/fr.po: Installed an updated translation.
4200 Resolves Debian bug #106720.
4202 2001-06-13 Paul D. Smith <psmith@gnu.org>
4204 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
4207 2001-06-11 Paul D. Smith <psmith@gnu.org>
4209 * i18n/ko.po: Installed a new translation.
4211 2001-05-06 Paul D. Smith <psmith@gnu.org>
4213 Modify the EINTR handling.
4215 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
4216 the way in which we manage the file descriptor/signal handler race
4217 trap to be more efficient.
4219 2001-05-06 Paul Eggert <eggert@twinsun.com>
4221 Restart almost all system calls that are interrupted, instead
4222 of worrying about EINTR. The lone exception is the read() for
4225 * configure.in (HAVE_SA_RESTART): New macro.
4226 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
4227 * main.c (main): Use SA_RESTART instead of the old,
4228 nonstandard SA_INTERRUPT.
4230 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
4231 * main.c (bsd_signal): New function or macro,
4232 if the implementation doesn't supply it.
4233 (The bsd_signal function will be in POSIX 1003.1-200x.)
4234 (HANDLESIG): Remove.
4235 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
4237 * make.h (EINTR_SET): Remove.
4238 (SA_RESTART): New macro.
4240 * arscan.c (ar_member_touch): Don't worry about EINTR.
4241 * function.c (func_shell): Likewise.
4242 * job.c (reap_children, free_child, new_job): Likewise.
4243 * main.c (main): Likewise.
4244 * remake.c (touch_file, name_mtime): Likewise.
4246 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
4247 if fstat failed with errno!=EINTR, the error was ignored.
4249 * job.c (set_child_handler_action_flags): New function.
4250 (new_job): Use it to temporarily clear the SIGCHLD action flags
4251 while reading the token.
4253 2001-05-02 Paul D. Smith <psmith@gnu.org>
4255 * job.c (start_job_command): Don't add define/endef per-line flags
4256 to the top-level flags setting.
4258 2001-04-03 Paul D. Smith <psmith@gnu.org>
4260 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
4261 bit on error, so check for odd return values, not non-0 return
4263 (VMS_get_member_info): Calculate the timezone differences correctly.
4264 Reported by John Fowler <jfowler@nyx.net>.
4267 2001-03-14 Paul D. Smith <psmith@gnu.org>
4269 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
4270 value before invoking define_variable().
4271 Reported by John Fowler <jfowler@nyx.net>.
4273 2001-02-07 Paul D. Smith <psmith@gnu.org>
4275 * read.c (record_target_var): If we reset the variable due to a
4276 command-line variable setting overriding it, turn off the "append"
4279 2001-01-17 Paul D. Smith <psmith@gnu.org>
4281 * variable.c (lookup_variable) [VMS]: When getting values from the
4282 environment, allocate enough space for the _value_ plus escapes,
4283 not enough space for the name plus escapes :-/.
4284 Reported by John Fowler <jfowler@nyx.net>.
4286 * remake.c (f_mtime): Removed the "***" prefix from the mod time
4287 warnings that make generates, so it doesn't look like an error.
4288 Reported by Karl Berry <karl@gnu.org>.
4291 Fix for PR/2020: Rework appended target-specific variables. I'm
4292 fairly confident this algorithm is finally correct.
4294 * expand.c (allocated_variable_append): Rewrite. Instead of
4295 expanding each appended variable then adding all the expanded
4296 strings together, we append all the unexpanded values going up
4297 through the variable set contexts, then expand the final result.
4298 This behaves just like non-target-specific appended variable
4299 values, while the old way didn't in various corner cases.
4300 (variable_append): New function: recursively append the unexpanded
4301 value of a variable, walking from the outermost variable scope to
4303 * variable.c (lookup_variable): Remove the code that looked up the
4304 variable set list if the found variable was "append". We don't
4306 (lookup_variable_in_set): Make this non-static so we can use it
4308 (try_variable_definition): Use lookup_variable_in_set() rather
4309 than faking out current_variable_set_list by hand (cleanup).
4310 * variable.h: Add a prototype for the now non-static
4311 lookup_variable_in_set().
4313 2000-11-17 Paul D. Smith <psmith@gnu.org>
4315 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
4316 WINDOWS32 port to assume timestamps can be up to 3 seconds away
4317 before throwing a fit.
4319 2000-11-17 Paul D. Smith <psmith@gnu.org>
4321 * read.c (readline): CRLF calculations had a hole, if you hit the
4322 buffer grow scenario just right. Reworked the algorithm to avoid
4323 the need for len or lastlen at all. Problem description with
4324 sample code chages provided by Chris Faylor <cgf@redhat.com>.
4326 2000-10-24 Paul D. Smith <psmith@gnu.org>
4328 * gettext.c (SWAP): Declare this with the prototype, otherwise
4329 some systems don't work (non-32-bit? Reported for Cray T3E).
4330 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
4332 2000-10-05 Paul D. Smith <psmith@gnu.org>
4334 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
4335 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
4337 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
4339 2000-09-22 Paul D. Smith <psmith@gnu.org>
4341 * gettext.c: Don't #define _GETTEXT_H here; we only include some
4342 parts of the real gettext.h here, and we expect to really include
4343 the real gettext.h later. If we keep this #define, it's ignored.
4345 2000-09-21 Paul D. Smith <psmith@gnu.org>
4347 * main.c (log_working_directory): Rework the text to use complete
4348 sentences, to make life simpler for the translators.
4350 2000-08-29 Paul D. Smith <psmith@gnu.org>
4352 * file.c (remove_intermediates): Print a debug message before we
4353 remove intermediate files, so the user (if she uses -d) knows
4356 2000-08-21 Paul D. Smith <psmith@gnu.org>
4358 * variable.c (try_variable_definition): Change how we handle
4359 target-specific append variable defns: instead of just setting the
4360 value, expand it as an append _but_ only within the current
4361 target's context. Otherwise we lose all but the last value if the
4362 variable is appended more than once within the current target
4363 context. Fixes PR/1831.
4365 2000-08-16 Paul D. Smith <psmith@gnu.org>
4367 * function.c (func_shell): Nul-terminate the buffer before
4368 printing an exec error message (just in case it's not!).
4369 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
4371 2000-07-25 Paul D. Smith <psmith@gnu.org>
4373 * job.c (construct_command_argv_internal): Add "~" to the list of
4374 sh_chars[] which disallow optimizing out the shell call.
4376 2000-07-23 Paul Eggert <eggert@twinsun.com>
4378 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
4379 supersedes --disable-nsec-timestamps.
4380 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
4381 * README: Remove --disable-nsec-timestamps.
4383 * filedef.h (struct file.low_resolution_time): New member.
4384 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
4385 * remake.c (update_file_1):
4386 Avoid spurious rebuilds due to low resolution time stamps,
4387 generalizing the earlier code that applied only to archive members.
4388 (f_mtime): Archive members always have low resolution time stamps.
4390 * configure.in: Remove --disable-nsec-timestamps, as this has
4391 been superseded by .LOW_RESOLUTION_TIME.
4393 2000-07-23 Paul Eggert <eggert@twinsun.com>
4395 * configure.in (enable_nsec_timestamps): Renamed from
4396 make_cv_nsec_timestamps, since enable/disable options
4397 shouldn't be cached.
4399 2000-07-23 Bruno Haible <haible@clisp.cons.org>
4400 and Paul Eggert <eggert@twinsun.com>
4402 * file.c (file_timestamp_now):
4403 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
4404 so that clock_gettime is not linked unless needed.
4406 * filedef.h (FILE_TIMESTAMP_HI_RES):
4407 Remove definition; "configure" now does this.
4409 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
4410 to before high resolution file timestamp check,
4411 since that check now uses uintmax_t.
4412 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
4413 high resolution file timestamps.
4414 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
4415 so that we don't link in clock_gettime unnecessarily.
4417 2000-07-17 Paul D. Smith <psmith@gnu.org>
4419 * i18n/ja.po: New version of the translation file.
4421 2000-07-07 Paul D. Smith <psmith@gnu.org>
4423 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
4424 the offset calculation.
4425 (name_mtime): Replace EINTR test with EINTR_SET macro.
4427 2000-07-07 Paul Eggert <eggert@twinsun.com>
4431 * remake.c (update_file_1):
4432 Avoid spurious rebuilds of archive members due to their
4433 timestamp resolution being only one second.
4434 (f_mtime): Avoid spurious warnings of timestamps in the future due to
4435 the clock's resolution being lower than file timestamps'.
4436 When warning about future timestamps, report only the discrepancy,
4437 not the absolute value of the timestamp and the current time.
4439 * file.c (file_timestamp_now): New arg RESOLUTION.
4440 * filedef.h (file_timestamp_now): Likewise.
4441 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
4443 2000-07-05 Paul D. Smith <psmith@gnu.org>
4445 * variable.c (lookup_variable) [VMS]: Remove vestigial references
4446 to listp. Fixes PR/1793.
4448 2000-06-26 Paul Eggert <eggert@twinsun.com>
4450 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
4452 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
4454 * remake.c (f_mtime): Remove unused var memtime.
4456 2000-06-25 Martin Buchholz <martin@xemacs.org>
4458 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
4459 Ran spell-check on make.texinfo.
4461 2000-06-23 Paul D. Smith <psmith@gnu.org>
4463 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
4464 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
4465 * make.h: Define these macros.
4467 * Version 3.79.1 released.
4469 * configure.in: Add a new option, --disable-nsec-timestamps, to
4470 avoid using sub-second timestamps on systems that support it. It
4471 can lead to problems, e.g. if your makefile relies on "cp -p".
4472 * README.template: Document the issue with "cp -p".
4474 * config.guess, config.sub: Updated.
