+
+ * arscan.c (ar_scan): New local var NAMEMAP.

+ unless <unistd.h> declared it; and we conflicted with some systems.
+
+ * main.c (define_makeflags): If FLAGSTRING[1] is '-', define
+ MAKEFLAGS to all of FLAGSTRING, not &FLAGSTRING[1]. Don't want to

+ (init_switches): Don't put such switches into the string, only
+ into the long_option table.
+
+ * make.h [!NSIG] [!_NSIG]: #define NSIG 32.
+
+ * job.c [HAVE_WAITPID]: Remove #undef HAVE_UNION_WAIT. AIX's
+ bsdcc defined WIF* to use union wait.
+
+ * main.c (struct command_switch): Change member `c' to type int.
+ (switches): Make const.
+ (decode_switches): Use `const struct command_switch *'.

+ [HAVE_SIGSETMASK]: Test this rather than USG.
+ [__GNU_LIBRARY__ || POSIX]: Don't #include <unistd.h> again.
+ * main.c (main): Handle SIGCHLD if defined, and SIGCLD if defined.
+ It doesn't hurt to do both if they are both defined, and testing
+ USG is useless.
+ * dir.c: Rationalize directory header conditionals.
+ * arscan.c [HAVE_FCNTL_H]: Test this rather than USG || POSIX.
+
+ * default.c (default_suffixes): Add `.txinfo'.
+ (default_suffix_rules): Add `.txinfo.info' and `.txinfo.dvi' rules.
+
+ * variable.c (try_variable_definition): Replace RECURSIVE flag
+ with enum FLAVOR, which can be simple, recursive, or append.
+ Recognize += as append flavor. Set new variable VALUE in a switch
+ on FLAVOR. For append flavor, prepend the variable's old value.
+ If the variable was previously defined recursive, set FLAVOR to
+ recursive; if it was defined simple, expand the new value before
+ appending it to the old value. Pass RECURSIVE flag to
+ define_variable iff FLAVOR == recursive.
+
+ * variable.c (try_variable_definition): Use alloca and bcopy for
+ NAME, instead of savestring. Might as well use stack storage

+ Always take a job off the chain and call start_waiting_job on it;
+ give up and return when start_waiting_job returns zero.
+
+ * main.c (define_makeflags: struct flag): Change member `char c' to
+ `struct command_switch *switch'.
+ (ADD_FLAG): Set that to CS instead of CS->c.

+ When writing out FLAGS, handle FLAGS->switch->c == -1 and write
+ the long name instead.
+
+ * compatMakefile (stamp-config): New target of old config.h rule.

+ (print_rule_data_base): Don't record info on `subdir' flags.
+
+ * implicit.c (pattern_search): Check the DEP->changed flag rather

+ flag is set.
+
+ * rule.c (count_implicit_rule_limits): Pass "", not ".", as file
+ name arg to dir_file_exists_p to check for existence of directory.
+
+ * implicit.c (pattern_search): Inside dep-finding loop, set

+
+ * commands.c (set_file_variables): Must alloca space for PERCENT
+ and copy it, to avoid leaving the trailing `)' in the value.
+
+ * misc.c (remove_comments): Fixed backslash-checking loop

+
+ * vpath.c (vpath_search): Take second arg MTIME_PTR, pass thru to

+
+ * Version 3.63.3.

+
+ Make -, @, and + prefixes on a pre-expanded command line affect
+ all lines in the expansion, not just the first.
+ * commands.h (struct commands): Replace `lines_recurse' member
+ with `lines_flags'.
+ (COMMANDS_{RECURSE,SILENT,NOERROR}): New macros, bits to set in

+ `lines_recurse'. Record not only + but also @ and - prefixes.
+ * remake.c (notice_finished_file): Check the COMMANDS_RECURSE bit
+ in FILE->cmds->lines_flags, rather than FILE->cmds->lines_recurse.
+ * job.c (start_job_command): Replaced RECURSIVE and NOPRINT local

+ Set CHILD->noerror if the COMMANDS_NOERROR bit is set in FLAGS.
+ Set the COMMANDS_SILENT bit in FLAGS for a @ prefix.
+
+ * remake.c (update_goal_chain): Set G->file to its prev after
+ checking for G being finished, since that check needs to examine
+ G->file.
+
+ * configure.in (union wait check) [HAVE_WAITPID]: Try using
+ waitpid with a `union wait' STATUS arg. If waitpid and union wait
+ don't work together, we should not use union wait.
+
+ * Version 3.63.2.
+
+ * remake.c (update_goal_chain): When G->file->updated, move

+
+ * compatMakefile (SHELL): Define to /bin/sh for losing Unix makes.
+
+ * main.c (decode_env_switches): Allocate (1 + LEN + 1) words for

+
+Wed Feb 3 18:13:52 1993 Roland McGrath (roland@geech.gnu.ai.mit.edu)
+
+ * compatMakefile ($(bindir)/$(instname)): Put - before
+ install_setgid command line, so its failure won't be an error.
+ (infodir): New variable.
+ (install): Depend on $(infodir)/$(instname).info.
+ ($(infodir)/$(instname).info): New target.
+
+ * read.c (read_makefile): If FILENAMES is nil when we see a line
+ starting with a tab, don't treat it as a command. Just fall
+ through, rather than giving an error.
+
+ * read.c (read_makefile): If the NO_TARGETS flag is set when we see a
+ command line, don't clear it before continuing. We want
+ subsequent command lines to be ignored as well.
+
+ * job.c (new_job): Before expanding each command line, collapse
+ backslash-newline combinations that are inside var or fn references.
+
+Mon Feb 1 16:00:13 1993 Roland McGrath (roland@geech.gnu.ai.mit.edu)

+
+Sun Jan 31 19:11:05 1993 Roland McGrath (roland@geech.gnu.ai.mit.edu)
+
+ * read.c (read_makefile): In vpath parsing, after finding the
+ pattern token, take entire rest of line as the search path, not
+ just the next token.
+
+ * compatMakefile (remote.o): Depend on remote-*.c.
+
+Thu Jan 28 16:40:29 1993 Roland McGrath (roland@churchy.gnu.ai.mit.edu)
+
+ * commands.c (set_file_variables): Don't define any F or D versions.
+ * variable.c (define_automatic_variables): Define them here as
+ recursively-expanded variables that use the dir and notdir funcs.
+
+ * variable.c (target_environment): In v_default case, don't export
+ o_default or o_automatic variables.
+
+ * configure.in (union wait check): Remove ` and ' inside C code;
+ they confuse the shell script.
+
+Mon Jan 25 13:10:42 1993 Roland McGrath (roland@churchy.gnu.ai.mit.edu)
+
+ * Version 3.63.1.
+
+ * vpath.c (construct_vpath_list): When skipping further processing
+ of an elt that is ".", don't also skip the code that pushes P past
+ the next separator.
+
+ * compatMakefile (distclean): Don't remove make-*.
+
+ * configure.in (HAVE_UNION_WAIT): Try to use WEXITSTATUS if it's
+ defined. If one cannot use WEXITSTATUS with a `union wait'
+ argument, we don't want to believe the system has `union wait' at all.
+
+ * remake.c (update_file): Do nothing to print "up to date" msgs.
+ (update_goal_chain): Do it here instead.
+ Use the `changed' flag of each goal's `struct dep' to keep track
+ of whether files_remade (now commands_started) changed around a
+ call to update_file for that goal.
+ When a goal is finished, and its file's update_status is zero (i.e.,
+ success or nothing done), test the `changed' flag and give an "up
+ to date" msg iff it is clear.
+ * make.h (files_remade): Renamed to commands_started.
+ * remake.c: Changed defn.
+ (update_goal_chain): Changed uses.
+ * job.c (start_job_command): Increment commands_started here.
+ (reap_children): Not here.
+
+ * remake.c (update_goal_chain): Don't do anything with files'
+ `prev' members. update_file now completely handles this.
+
+ * variable.c (target_environment): Don't expand recursive
+ variables if they came from the environment.
+
+ * main.c (define_makeflags): For flags with omitted optional args,
+ store {"", 0} with ADD_FLAG. When constructing FLAGSTRING, a flag
+ so stored cannot have more flags appended to the same word.
+
+Fri Jan 22 14:46:16 1993 Roland McGrath (roland@churchy.gnu.ai.mit.edu)
+
+ * variable.c (print_variable_set): In vars/bucket calculation,

+
+ * job.c [!HAVE_UNION_WAIT] (WTERMSIG, WCOREDUMP, WEXITSTATUS):
+ Don't define if already defined.
+
+ * remake.c (update_file): Don't keep track of the command_state before
+ calling update_file_1. Remove local variable COMMANDS_FINISHED,
+ and don't test it to decide to print the "is up to date" msg.
+ Testing for files_remade having changed should always be sufficient.
+ The old method lost when we are called in the goal chain run on a
+ makefile, because the makefile's command_state is already
+ `cs_finished' from the makefile chain run.
+
+ * misc.c [HAVE_SETRE[GU]ID]: Test these to decl setre[gu]id.
+
+ * configure.in: Rewrote wait checking.
+ Use AC_HAVE_HEADERS to check for <sys/wait.h>.

+ * job.c: Rewrote conditionals accordingly.
+ [HAVE_WAITPID]: Test this only to define WAIT_NOHANG.

+ * configure.in: Set CFLAGS and LDFLAGS before all checks.
+
+ * dir.c: Add static forward decls of {open,read}_dirstream.

+ * job.c [NGROUPS_MAX && NGROUPS_MAX==0]: #undef NGROUPS_MAX.
+
+ * compatMakefile (CFLAGS, LDFLAGS): Set to @CFLAGS@/@LDFLAGS@.
+ * build.template (CFLAGS, LDFLAGS): Same here.
+ * configure.in: AC_SUBST(CFLAGS) and LDFLAGS.
+ Set them to -g if not defined in the environment.
+
+ * remake.c (library_search): Use LIBNAME consistently, setting it
+ only once, to be the passed name sans `-l'.
+ Pass new var FILE to be modified by vpath_search.
+
+Mon Jan 18 14:53:54 1993 Roland McGrath (roland@churchy.gnu.ai.mit.edu)
+
+ * Version 3.62.30.
+
+ * job.c (start_waiting_jobs): Return when job_slots_used is equal to
+ job_slots.
+
+ * configure.in: Add AC_CONST for the sake of getopt.
+
+ * read.c (read_makefile): Continue after parsing `override'
+ directive, rather than falling through to lossage.
+ Check for EOL or blank after "override define".
+
+ * compatMakefile (.c.o, remote.o): Put $(CFLAGS) after other switches.
+
+Fri Jan 15 12:52:52 1993 Roland McGrath (roland@churchy.gnu.ai.mit.edu)
+
+ * Version 3.62.29.
+
+ * main.c (define_makeflags): After writing everything into
+ FLAGSTRING, only back up two chars if [-1] is a dash, meaning we
+ just wrote " -". Always terminate the string at *P.
+
+ * remake.c (library_search): When constructing names in std dirs,
+ use &(*LIB)[2] for the stem, not LIBNAME (which points at the
+ buffer we are writing into!).
+
+Thu Jan 14 13:50:06 1993 Roland McGrath (roland@churchy.gnu.ai.mit.edu)
+
+ * read.c (read_makefile): Set IN_IGNORED_DEFINE for "override

+
+ * main.c (die): Call print_data_base if -p.
+ (main): Don't call it here.
+
+ * compatMakefile (defines): Add @DEFS@. configure should turn this
+ into -DHAVE_CONFIG_H.
+
+Mon Jan 11 14:39:23 1993 Roland McGrath (roland@geech.gnu.ai.mit.edu)
+
+ * Version 3.62.26.

+ * read.c (read_makefile): Add missing parens in if stmt that find
+ conditional directives.
+
+ * main.c (main): Declare init_dir.

+
+ * Version 3.62.25.
+
+ * job.c [HAVE_SYS_WAIT || !USG]: Don't #include <sys/time.h> and

+
+ * configure.in (AC_HAVE_FUNCS): Check for setre[gu]id.
+ * misc.c ({user,make}_access): Test #ifndef HAVE_SETRE[GU]ID, not

+ * misc.c ({user,make,child}_access): Give name of caller in error msgs.
+
+ * job.c (load_too_high): Say "cannot enforce load limit" in error msg.
+
+ * configure.in: Call AC_PROG_CC.

+
+ * main.c (decode_switches): If a switches elt has a nil long_name,
+ make the long option name elt be "".
+ Fixed loop to not ignore all the options.
+
+ * make.texinfo (Option Summary): Added long options.
+
+ * main.c (switches): Changed -m's description to "-b".
+ (decode_switches): When printing the usage message, don't print
+ switches whose descriptions start with -.
+ When constructing the list of names for switch -C, search the
+ switches vector for switches whose descriptions are "-C".
+
+ * main.c (switches): Call -S --no-keep-going, not --dont-keep-going.
+ Call -I --include-dir, not --include-path.
+ (long_option_aliases): Added --new == -W, --assume-new == -W,

+ --makefile == -f.
+
+ * main.c (switches): Removed bogus "silent" elt.
+ (long_option_aliases): Define new var.
+ (decode_switches): Add long_option_aliases onto the end of the long

+ This happened when multiple SIGCHLDs before reap_children was called.
+
+ * job.c (reap_children): If ERR is set, so we don't call start_job
+ on the child being reaped, instead set its command_state to
+ cs_finished.
+ (reap_children, child_handler, new_job): I added several
+ debugging printf's while fixing this. I left them in if (debug_flag)
+ because they may be useful for debugging this stuff again.

+ * commands.c (chop_commands): Don't botch the line count for allocating
+ CMDS->lines_recurse.
+
+ * Version 3.58.11.
+
+ * job.c (start_job): Don't always increment CHILD->command_line! Only
+ do it when CHILD->command_ptr has run out! (Dumb bug. Sigh.)
+
+Thu Sep 20 02:18:51 1990 Roland McGrath (roland at geech.ai.mit.edu)
+
+ * GNUmakefile [ARCH]: Give explicit rule for remote.{c,dep} to use
+ variable `REMOTE' for more flags.
+ ($(prog)): Link in $(LOADLIBES).
+
+Wed Sep 19 02:30:36 1990 Roland McGrath (roland at churchy.ai.mit.edu)
+
+ * commands.h (struct commands): New member `ncommand_lines', the number
+ of elts in `command_lines' et al.
+ * commands.c (chop_commands): Set `ncommand_lines' elt of CMDS, and
+ don't put a nil pointer at the end of `command_lines'.
+ * job.h (struct child): New member `command_lines' to hold

+ being expanded.
+ (recursively_expand): Don't test and set `expanding' member.
+ Instead, run through the `variables_expanding' chain looking for a link
+ referring to V to find self-reference. Add a new link to the chain,
+ describing V, before recursive expansion, and pop it off afterward.
+ * job.c (child_handler): Save `variables_expanding' and clear it before
+ calling start_job, and restore it afterward. This avoids major lossage
+ when the SIGCHLD comes in the middle of variable expansion.
+
+Mon Sep 17 14:46:26 1990 Roland McGrath (roland at geech.ai.mit.edu)
+
+ * job.c, commands.c: Don't define sigmask.

+ * job.c [USG] (unknown_children_possible): New variable, set nonzero
+ when it's possible for children not in the `children' chain to die.
+ (block_signals) [USG]: Set it.
+ (unblock_signals) [USG]: Clear it.
+ (child_handler) [USG]: Don't complain about unknown children if
+ `unknown_children_possible' is set.
+
+ * read.c (do_define): Make sure there's enough space for the newline,
+ so we don't write off the end of allocated space.
+
+ * arscan.c (ar_name_equal): Fixed to work when MEM is AR_NAMELEN-1 but

+
+Sat Aug 25 16:17:14 1990 Roland McGrath (roland at geech)
+
+ * job.c (construct_command_argv_internal): Use a static char array for

+ * main.c (main): Don't pass path and shell to exec_command.
+
+Fri Aug 17 23:17:27 1990 Roland McGrath (roland at geech)
+
+ * job.c (construct_command_argv_internal): New fn broken out of
+ construct_command_argv. Takes strings SHELL and IFS instead of doing
+ variable expansion for them. Recurse to make an argv for SHELL,
+ passing SHELL==0. When SHELL==0, don't recurse for shell argv; make a
+ simple one using /bin/sh.
+ (construct_command_argv): Do the variable expansions and call above.
+
+Thu Aug 16 19:03:14 1990 Roland McGrath (roland at geech)

+Mon Aug 6 14:35:06 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * Version 3.58.8.
+
+ * main.c (decode_switches): For positive_int and floating cases, move
+ SW past the arg (and don't set it to ""), so another switch can follow.
+
+Fri Aug 3 00:43:15 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * job.c (child_execute_job): Use unblock_signals instead of

+ Block/unblock both child signal and signals in fatal_signal_mask.
+ (children_blocked_p_{stack,max,depth}, {push,pop}_children_blocked_p):
+ Renamed from children to signals. Use {block,unblock}_signals instead
+ of {block,unblock}_children.
+ * commands.c (fatal_error_signal), job.c (wait_for_children, new_job,
+ child_execute_job, main, log_working_directory), function.c
+ (expand_function: `shell'), job.h: Rename {push,pop}_children_blocked_p
+ to {push,pop}_signals_blocked_p.
+ * job.c (child_handler): Call {block,unblock}_signals instead of just
+ {block,unblock}_remote_children. We need to block the fatal signals.
+

+
+Fri Jul 20 15:30:26 1990 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * arscan.c (ar_name_equal): Rewritten. Accounts for a possible

+
+Sat Jul 14 13:41:24 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * job.c (construct_command_argv): Always use
+ allocated_variable_expand_for_file instead of variable_expand_for_file
+ because we might be called from inside a variable expansion (for the
+ `shell' function).
+
+ * function.c (expand_function: `shell'): Free the arglist's storage
+ correctly. construct_command_argv only allocates ARGV and ARGV[0].
+
+ * job.c (children_blocked_p_idx): Renamed to children_blocked_p_depth.
+ (push_children_blocked_p, pop_children_blocked_p): Use ..._depth
+ instead of ..._idx, and do it right!
+
+Wed Jul 11 15:35:43 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * make.h (SIGNAL): New macro to replace `signal' calls. Does arg and

+
+Fri Jul 6 00:00:38 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU)

+
+ * file.h (struct file), main.c (struct command_switch): Remove trailing
+ commas from enums.
+
+ * commands.c (execute_file_commands): Remove unused variables.
+ * commands.h: Declare chop_commands.

+ * ar.c: Declare ar_name_equal.
+
+ * GNUmakefile: If using gcc, add warning flags to CFLAGS.
+
+ * remake.c: Remove decl of ar_member_date, since it's done in make.h.

+ * remake.c (f_mtime): For ar refs, allow the archive to be found via
+ VPATH search if we're searching, and change the ar ref accordingly.
+
+ * ar.c (ar_parse_name): New global fn to parse archive-member
+ references into the archive and member names.
+ (ar_member_date, ar_touch): Use it.
+ * make.h: Declare it.
+

+ of assuming rename_file will always set FILE->renamed (which it won't).
+
+ * vpath.c (selective_vpath_search): Only accept prospective files that
+ don't actually exist yet are mentioned in a makefile if the file we are
+ searching for isn't a target.

+ * file.c (rename_file): Prettied up long message for merging cmds.
+
+ * remake.c (update_file_1): Get each dep file's modtime, and allow for
+ it being renamed, before checking for a circular dep, since a renaming
+ may have introduced one.
+
+Tue Jul 3 18:15:01 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU)
+
+ * ar.c (ar_touch): Don't free ARNAME since enter_file holds onto the
+ storage.

+
+Mon Jul 2 14:10:16 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU)
+
+ * implicit.c (pattern_search): No longer take NAME arg. Instead take
+ ARCHIVE flag. If ARCHIVE is nonzero, FILE->name is of the form
+ "LIB(MEMBER)"; rule for "(MEMBER)" is searched for, and LASTSLASH is
+ set to nil. Since NAME was only non-nil when it was the archive member
+ name passed by try_implicit_rule, this change easily allows turning off
+ LASTSLASH checking for archive members without excessive kludgery.
+ (try_implicit_rule): Pass ARCHIVE flag instead of file name.
+
+ * Version 3.58.5.
+
+ * commands./c (set_file_variables): Don't kill last char of $(^D) elts.

+
+ * arscan.c (ar_scan) [sun386 && PORTAR == 1]: Treat like USGr3.
+
+Wed Jun 27 14:38:49 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * main.c (main): Put a newline on the debugging message when deciding
+ not to remake a makefile to avoid a possible loop.
+ Only decide not to remake makefiles that have commands (as well as
+ being targets and having no deps).
+
+Fri Jun 22 12:35:37 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * default.c (default_variables): Define `LINK.s' and `LINK.S'.

+
+ * job.c (construct_command_argv): If we decide to go the slow route,
+ free all storage for the chopped args.
+ (start_job): Free the argument list's storage correctly.
+ construct_command_argv only allocates ARGV and ARGV[0].
+
+Tue Jun 19 18:27:43 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)

+Thu Jun 7 00:30:46 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * dir.c: Copied dirent vs direct et al mess from glob.c.
+
+ * glob.c: Replaced with updated version from djm.
+ * glob.c: Check macro DIRENT instead of _POSIX_SOURCE for <dirent.h>.
+ __GNU_LIBRARY__ implies DIRENT and STDC_HEADERS.
+
+Thu May 31 22:19:49 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * vpath.c (vpath_search): Don't stop the loop if a pattern matches but
+ the search fails. All matching patterns have their paths searched
+ (like it says in the manual).
+
+ * make.texinfo (Rules: Directory Search: Selective Search): Say that
+ multiple `vpath' directives with the same pattern DO accumulate, not
+ supersede earlier ones.
+
+ * vpath.c (print_vpath_data_base): Increment the count of vpaths on
+ each loop iteration, rather than letting it stay zero.
+
+ * Version 3.58.3.
+
+ * job.c (block_children, unblock_children): Made static.
+ (push_children_blocked_p, pop_children_blocked_p): New functions to
+ push and pop whether children are blocked or not.
+ * job.h: Declare push_children_blocked_p, pop_children_blocked_p and
+ not block_children, unblock_children.
+ * commands.c (fatal_error_signal), job.c (wait_for_children, new_job,
+ child_execute_job), main.c (main, log_working_directory): Use sequences
+ of push_children_blocked_p (1) and pop_children_blocked_p () instead of
+ explicitly blocking and unblocking children.
+ * function.c (expand_function: `shell'): Don't unblock children. The
+ push-pop sequence in wait_for_children makes it unnecessary.
+
+Tue May 29 21:30:00 1990 Roland McGrath (mcgrath at helen.Berkeley.EDU)
+
+ * read.c (do_define): Don't include the last newline in the definition.
+
+ * function.c (expand_function: `shell'): Call construct_command_argv
+ before forking and don't fork if it returns nil. Free the argument
+ list's storage before finishing.
+
+ * job.c (start_job): Free the storage for the child's argument list
+ in the parent side of the fork after the child has been spawned.
+
+ * job.c (start_job): If construct_command_argv returns nil, go to the

+ * job.c (construct_command_argv): Use the shell if the command contains
+ an unterminated quote.
+
+Wed May 23 19:54:10 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * Version 3.58.2.
+
+ * read.c (read_makefile): Parse "override define" correctly.
+
+Thu May 17 15:25:58 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * arscan.c [USG]: Don't declare memcpy and memcmp. <memory.h> should
+ do this anyway (and lack of declarations is harmless).
+
+ * remote-customs.c: Renamed to remote-cstms.c for System V.
+ * remote.c [CUSTOMS]: Changed accordingly.
+
+Sun May 13 14:38:39 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * GNUmakefile: Use same cmds for doc tar.Z as for dist tar.Z (so the
+ contents go in make-N.NN).
+
+Thu Apr 26 19:33:25 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU)
+
+ * Version 3.58.1.
+
+Wed Apr 25 20:27:52 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU)
+
+ * job.c (init_siglist): Don't do SIGUSR1 and SIGUSR2 if they are the
+ same as SIGIO and SIGURG (true on Cray).
+
+Tue Apr 24 20:26:41 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU)
+
+ * arscan.c (ar_scan): Do behavior for PORTAR == 1 and USGr3 also
+ #ifdef APOLLO.
+
+Wed Apr 11 10:00:39 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * job.c (exec_command): Set the effective GID to the real GID. Somehow

+
+ * default.c (default_variables: PREPROCESS.S): Removed $< from defn.
+

+
+ * rule.c (count_implicit_rule_limits): Redid loop control to not run
+ twice on freed rules.
+
+ * GNUmakefile: Made `.dep' files be architecture-specific too.
+
+ * main.c (main, log_working_directory) [USG]: Block children around
+ calls to `getwd' (actually `getcwd' on USG), because that function
+ sometimes spawns a child running /bin/pwd on USG.
+
+Tue Jan 30 14:02:50 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU)
+

+
+Sat Jan 20 11:52:01 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU)
+
+ * file.c (rename_file): Don't free the storage for the old name, since
+ it might not have been malloc'd.
+
+ * job.c (construct_command_argv): Call
+ allocated_variable_expand_for_file instead of variable_expand_for_file
+ to expand `$(SHELL)'.
+
+ * make.texinfo (Bugs): Change address from roland@wheaties.ai.mit.edu

+ it.
+ * variable.c (merge_variable_sets): New fn to merge two variable sets.
+ (merge_variable_set_lists): New fn to merge two variable set lists.

+
+ * make.texinfo (Rules: Wildcards: Wildcard Examples): Give this node a

+
+ * remake.c (update_goal_chain): If -n or -q is in effect for a

+
+ * remake.c (notice_finished_file): Treat -q the same as -n.

+
+ * remake.c (remake_file): If FILE has no commands and is a target,

+
+ * read.c (read_makefile): Don't read off the end of the string after an
+ `include'.
+
+ * job.c (exec_command): New function to search the path for a file and

+ loop to close all file descriptors other than 0, 1, and 2. We need to
+ do this since not only the bad stdin pipe, but also some directories,
+ may be open.
+
+ * commands.c (start_job): Use fork instead of vfork, because a vfork
+ parent and child share file descriptors, and our child needs to diddle
+ with stdin.
+
+ * variable.c (initialize_file_variables): When created a new variable
+ set, zero out the hash table.
+
+ * variable.c (target_environment): Don't use variables whose names are
+ not made up of alphanumerics and underscores.
+
+ * remake.c (update_file_1): Set the `parent' member of each dependency
+ to FILE before updating it.
+
+ * file.h (struct file): Add `parent' member.
+
+ * variable.c (initialize_file_variables): Don't take second arg PARENT.
+ Use FILE->parent instead. If FILE->parent->variables is nil, recurse
+ to initialize it.
+
+ * variable.h: Declare {allocated_}variable_expand_for_file.
+
+ * variable.c (allocated_variable_expand): Now
+ allocated_variable_expand_for_file, calling variable_expand_for_file,
+ and taking second arg FILE.
+ (allocated_variable_expand): New function, a wrapper around
+ allocated_variable_expand_for_file, passing a nil second arg.
+
+Fri Jun 9 12:11:45 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * commands.c (start_job): On the child side of the fork, always close
+ the bad stdin file descriptor.
+
+ * commands.c (struct child): New member `environment', to hold the
+ environment for the child.
+ (execute_file_commands): Set the new childs `environment' member to nil
+ before calling start_job.
+ (start_job): Set up CHILD->environment before running the commands if
+ it is nil.
+
+ * make.c (main): Don't call new_environ. `shell' functions will now be
+ run with the environment make was called with.
+
+ * commands.c (child_handler): Don't check C->command_ptr before calling
+ start_job since we now have to check C->file->cmds->command_lines and
+ it's easier to let start_job handle all that.
+
+ * commands.c (struct child): New member `command_line', to hold an
+ index into file->cmds->command_lines.
+ (execute_file_commands): Set the new child's `command_line' to 0 and
+ its `commands' and `commands_ptr' to nil.
+ (start_job): When CHILD->command_ptr runs out, increment
+ CHILD->command_line and run the corresponding line from
+ CHILD->file->cmds->command_lines. Run it even under -t, -q, or -n if
+ the CHILD->file->cmds->lines_recurse element for that line is set.
+
+ * commands.c (execute_file_commands): Chop CMDS up into lines, setting
+ its `command_lines' and `lines_recurse' members, if it wasn't already
+ chopped.
+
+ * commands.h (struct commands): New members `command_lines' and
+ `lines_recurse'. The first is an array of chopped-up lines; the second
+ is an array of flags, each nonzero if the corresponding line is
+ recursive.
+
+ * variable.c (variable_expand_for_file): If FILE is nil, just do a
+ vanilla variable_expand.
+ (expand_function: `shell'): Pass second arg (as nil) to
+ construct_command_argv.
+
+ * commands.c (construct_command_argv): Use variable_expand_for_file on
+ `$(SHELL)' and `$(IFS)' instead of lookup_variable to check those
+ variables. This handles file-local and recursive values correctly.
+ To support this, take an additional argument FILE.
+
+ * variable.c (initialize_file_variables): New function to initialize
+ FILE's variable set list from PARENT's setlist. PARENT is the
+ immediate dependent that caused FILE to be remade, or nil if FILE is a
+ goal. (When user-level per-file variables are implemented, PARENT
+ should be passed as nil when defining per-file variables.)
+
+ * variable.c (variable_expand_for_file): New function to expand a line
+ using the variable set of a given file, and reporting error messages
+ for the file and line number of that file's commands.
+
+ * variable.h: Don't declare lookup_variable_for_file.
+
+ * variable.c (lookup_variable_*): Turned back into lookup_variable. It
+ now uses current_setlist.
+ (global_setlist): New static `struct variable_set_list', a setlist
+ containing global_variable_set.
+ (current_setlist): New static `struct variable_set_list *', a pointer
+ to the current variable set list.
+ (define_variable): Define in the current top-level set, not the global
+ set.
+
+ * commands.c (set_file_variables): New function to set up the automatic
+ variables for a file in its own variable set.
+ (execute_file_commands): Use set_file_variables.
+
+ * variable.c (new_environ): Replaced with target_environment, taking an
+ argument FILE, and returning an environment for FILE's commands.
+
+ * variable.c, variable.h: Remove all global special variable pointers.
+
+ * variable.c (define_variable_for_file): New function like
+ define_variable, but takes additional arg FILE, and defines the
+ variable in the variable set at the top of FILE's chain.
+ (lookup_variable_for_file): New function like lookup_variable, but
+ takes additional arg FILE, and looks the variable up in all of FILE's
+ variable sets.
+
+ * file.h (struct file): New member `variables', a `struct
+ variable_set_list' containing the list of variable sets used in the
+ expansion of the file's commands.
+
+ * variable.c (variables): Replaced with static `struct variable_set'
+ global_variable_set.
+ (define_variable): Now define_variable_in_set, taking additional
+ argument SET, the `struct variable_set' to define it in.
+ (define_variable): Use define_variable_in_set with global_variable_set.
+ (lookup_variable): Now lookup_variable_in_set, taking additional
+ argument SET, the `struct variable_set' to look it up in.
+ (lookup_variable): Use lookup_variable_in_set with global_variable_set.
+ (lookup_variable_in_setlist): New function to look up a variable in a
+ `struct variable_set_list' using lookup_variable_in_set.
+
+ * variable.h (struct variable_set): New structure, containing a hash
+ table and the number of hash buckets.
+ (struct variable_set_list): New structure, containing a link for a
+ linked-list, and a `struct variable_set'.
+
+ * commands.c (start_job): Under -n, return what the recursive start_job
+ call returns, since it might actually start a child.
+
+ * make.texinfo (Rules: Wildcards): Document ~ and ~USER expansion.
+
+ * commands.c (execute_file_commands): If start_job returns
+ failure, but -t is set, set FILE->update_status to success.
+ (start_job): If -t is set, and the commands are not recursive, return
+ failure (is is done for -q).
+
+ * remake.c (touch_file): New function to touch FILE.
+ (remake_file): Use touch_file. When touching a file, still do
+ execute_file_commands.
+
+ * remake.c (remake_file): Don't check question_flag (-q), since we
+ can't know here if the commands are recursive.
+
+ * commands.c (start_job): Don't use the `recursive' member of
+ CHILD->file->cmds. Instead, check for leading +s and $(MAKE) or
+ ${MAKE} in the command line here.
+
+ * commands.h (struct commands): Remove `recursive' member.
+
+ * rule.c (install_default_pattern_rules): Remove use of `recursive'
+ member.
+
+ * read.c (record_files): Don't check commands from $(MAKE) and set
+ their `recursive' member.
+
+ * commands.c (fatal_error_signal): Treat SIGQUIT like SIGINT, SIGHUP,
+ and SIGTERM, but don't send it to ourselves because it will cause a
+ core dump.
+
+Thu Jun 8 20:30:04 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * Version 3.50.
+
+ * variable.c (variable_expand): Use allocated_variable_expand instead
+ of expand_argument in a few places.
+
+ * variable.c (allocated_variable_expand): Do static variable shuffling
+ here instead of using expand_argument.
+ (expand_argument): Use allocated_variable_expand.
+
+ * variable.c (recursively_expand): New function to recursively expand
+ its argument (a `struct variable'), returning the malloc'd value.
+ (variable_expand): Use recursively_expand.
+
+Sun May 28 12:49:27 1989 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * make.c (main): Fixed buggy fix in deciding to increase space for
+ command-line variable definitions. (First it never did it, then it
+ always did it; now it does it when necessary.)
+
+Sat May 27 14:01:54 1989 Roland McGrath (mcgrath at hecuba.Berkeley.EDU)
+
+ * make.c (main): Fixed bug in deciding to increase space for

+
+Fri May 26 15:48:01 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * read.c (multi_glob): Use allocated_expand_variable for checking
+ `HOME' variable for ~ expansion, since this may be called from inside a
+ `wildcard' function expansion.
+
+ * variable.h: Declare allocated_expand_variable.
+
+ * variable.c (allocated_expand_variable): New function to do variable
+ expansion in an allocated buffer, rather than the static one.
+

+
+ * variable.c (string_glob): Use multi_glob and parse_file_seq.
+
+ * read.c (multi_glob): Do ~ expansion here.
+
+ * glob.c (glob_tilde, glob_filename): Removed ~ expansion.
+
+ * variable.c (define_variable, lookup_variable): Use a smarter hashing
+ algorithm (the same one used for files and directories).
+ (VARIABLE_BUCKETS): Increased to 523.
+
+ * file.c (enter_file, lookup_file, rename_file): Use a smarter hashing
+ algorithm, spreading the bits about somewhat.
+
+ * make.c (log_working_directory): Under `-p', precede the directory
+ message with a `#'.
+
+ * make.c (print_version): Under `-p', precede each line with a `#'.
+ (print_data_base): Precede the header line with a `#' and include the
+ date and time on it.
+
+ * vpath.c (print_vpath_data_base): Precede non-directive
+ lines with `#'s.
+
+ * commands.c (print_commands): Precede the non-command line with a `#'.
+
+ * rule.c (print_rule_data_base), file.c (print_file_data_base): Precede
+ non-rule lines with `#'s.
+
+ * dir.c (print_dir_data_base): Precede all lines with `#'s.
+
+ * variable.c (print_variable_data_base): Changed format so that it can
+ be makefile input. Lines that are not variable definitions are
+ preceded with `#'. Nonrecursive variable definitions are made with all
+ dollar signs doubled to reproduce the initial value. Recursive
+ variable definitions containing newlines are done with `define'
+ directives. Nonrecursive variable definitions containing newlines, and
+ variable names containing :, =, or newlines, will come out garbled.

+ * Version 3.49.
+
+Tue May 23 19:18:00 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * variable.c (expand_function: `filter'/`filter-out'): Use
+ find_percent instead of pattern_p.
+
+ * variable.c (expand_function: `patsubst'): Pass new args (both nil)
+ to patsubst_expand.
+ (variable_expand): For $(var:pat%=rep%) references, pass new args to
+ patsubst_expand so as to avoid find_percent and thus disallow
+ quoting the %s.
+
+ * read.c (record_files): Pass new args to patsubst_expand.
+
+ * variable.c (patsubst_expand): Take two new args: PATTERN_PERCENT
+ and REPLACE_PERCENT. Each of these, if non-nil, means that PATTERN
+ (or REPLACE) has already been run through find_percent, and
+ PATTERN_PERCENT (or REPLACE_PERCENT) is the result.
+
+ * make.h: Declare find_percent instead of pattern_p.
+
+ * read.c (pattern_p): Changed to find_percent, returning a pointer
+ to the %, or nil if there is none.

+
+ * make.texinfo (Rules: Static Pattern: Static Usage,

+
+ * read.c (pattern_p): Made global.
+ * make.h: Declare pattern_p.
+
+ * read.c (pattern_p): New function to search for an unquoted % in a
+ string. Backslashes quote %s and backslashes. Quoting backslashes
+ are removed from the string by compacting it into itself. Returns
+ nonzero if an unquoted % was found, zero if not.
+ (record_files): Use pattern_p to check for implicit rules.
+ (read_makefile): Use pattern_p to check for static pattern rules.
+ Also use it to allow quoted %s in `vpath' patterns; warn about
+ `vpath' patterns with no %s.

+Mon May 22 16:31:52 1989 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * glob.c (glob_filename): Replace a `1' with the `l' that should
+ have been there. This incidentally stops it from dumping core.
+
+ * glob.c (glob_filename): If the path is just a directory, with no
+ file name pattern, return the directory alone.
+
+ * glob.c (glob_tilde): New global variable (int), defaults to zero.
+ (glob_filename): If glob_tilde is nonzero, expand ~ or ~USER.
+
+ * variable.c (string_glob): Keep a static allocated buffer for file

+ member of the bottom `prev' file (the one whose `prev' is nil).
+
+ * read.c (do_define): Append newlines after copying the lines into

+ (child_handler): Use child_error instead of error_status.
+
+ * compatMakefile (all): Don't depend on `doc'.
+
+ * compatMakefile (clean): Don't remove make-info*.

+
+ * rule.c (default_variables): Set F77 to $(FC) and F77FLAGS to

+ make.h: Declare check_changed_directories.

+
+ * read.c (read_all_makefiles): Don't set *MAKEFILES to the name of
+ the end of the read_makefiles chain, since the latter may be from an
+ included makefile. (Why did I do this before?)
+
+ * make.c (main): Set argv[0] to "" if it was nil. Don't put the
+ command-line variable definitions into argv[0], only into the MAKE

+
+ * Version 3.35.

+ completes, set `shell_function_completed' to 1 if it actually ran,
+ or -1 if it didn't (due to fork or exec failure).

+ doesn't clobber the first one.
+
+ * make.texinfo: Documented default implicit rule changes.
+
+ * rule.c: Revamped default suffix rules. They now use Sun's style
+ of using variables `COMPILE.c', `LINK.c', etc. for each suffix, and
+ use `TARGET_ARCH' and `TARGET_MACH' variable where appropriate.
+ Also support Modula-2 compilation (suffixes .sym, .def, and .mod).
+ Ratfor Yacc support is gone, since nobody has yacc -r.
+ All EFL support is gone, since nobody uses EFL.
+

+
+ * variable.c (variable_expand): When checking for `$($(foo))', use
+ lindex so as not to search for the second `$' outside the parens.
+
+ * make.c (struct stringlist, main, decode_switches): Changed `index'
+ member to `idx'.
+
+Sat Dec 24 16:02:32 1988 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * commands.c (wait_for_children [USG]): Handle SIGCLD with SIG_DFL,
+ rather than SIG_IGN. Ignoring SIGCLD reportedly makes wait return -1.
+
+ * arscan.c [USGr3]: Define PORTAR to 1 (as with sun386).
+ (ar_scan [USGr3]): Remove trailing slashes from member names.
+

+
+ * read.c (read_all_makefiles, read_makefile): Make makefiles precious.
+
+ * make.c (decode_switches): For a positive_int or floating option,
+ if we moved to the next argument word, but found no argument for the
+ option, move back to the correct word.
+
+ * make.c (decode_switches): If we got any unknown options, die after
+ processing all arguments.
+
+ * GNUmakefile: Moved `include depend' to the end, so the default
+ goal will be set before then.
+
+ * load.c (wait_to_start_job [Unix, UMAX]): Merged into one version
+ under #ifdef LDAV_BASED. Only loop while we have jobs running.
+ Sleep for increasing amounts (increase one second per iteration)

+ start_job.
+
+ * commands.c (child_handler: USG): Record the pid wait returns.

+ * GNUmakefile: Make Makefile from oldMakefile and depend.
+
+ * read.c (read_all_makefiles): When putting the default makefiles in
+ the read_makefiles chain so they will be remade, put them in the
+ right order.
+
+ * remake.c (update_goal_chain): If MAKEFILES is nonzero, always make
+ in serial, and return as soon as one goal whose `changed' member is

+ which defines the two variables.
+ * variable.c (define_automatic_variables): Don't define MAKEFLAGS
+ and MFLAGS.

+
+ * Version 3.27.
+
+ * commands.c (child_handler): Reset the handler to ourselves when
+ called for USG, since it has no safe signals.
+
+ * commands.c: For USG, use an int rather than a `union wait' for
+ wait calls, and dissect it with bitmasks.
+ (child_handler): No wait3 system call in USG. Since we can't
+ protect from hanging, always return immediately if we have no
+ children we know about and we're not running a `shell' function.
+ (There is still the danger of hanging waiting for a child that died
+ without our being notified.)
+
+ * remake.c: Include <fcntl.h> instead of <sys/file.h>. What we need
+ is really in <fcntl.h>, and while BSD <sys/file.h> includes

+ which might need it (in a call to error or fatal).

+ directories we have open and don't let it be more than
+ MAX_OPEN_DIRECTORIES (currently 10).
+
+ * variable.c (expand_function: `foreach'): Use expand_argument
+ rather than variable_expand so each repetition doesn't clobber the
+ last!!!
+
+Mon Dec 5 15:58:46 1988 Roland McGrath (mcgrath at hecuba.Berkeley.EDU)
+
+ * Version 3.25.
+
+ * Makefile: Define `install' target.

+ before parsing rules so variable can contain special characters
+ (colons and semicolons).

+
+ * variable.c (expand_function: `filter', `filter-out'): Fixed so

+ functions use each word of their first argument as a pattern.
+
+Fri Nov 25 10:51:47 1988 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * Version 3.24.
+
+ * read.c (record_files): If a target is listed more than once in a
+ single rule (that defines commands), give a warning message rather
+ than the counter-intuitive message saying commands were already
+ defined (in the same place).
+
+ * make.c (fatal, error): Made them both take 6 args since there is

+ * read.c (read_makefile): Moved the construction of the `struct
+ commands' into record_files. Call record_files before recursing for an
+ included makefile so the higher-up will determine the default goal.
+ (record_files): Take arguments COMMANDS, COMMANDS_IDX and

+
+Thu Nov 24 14:36:33 1988 Roland McGrath (mcgrath at paris.Berkeley.EDU)

+
+ * make.c (main): Made it a fatal error if we can't move back to the
+ directory we started in before re-execing.
+
+ * make.c (main): Get the current directory before doing anything

+
+ * commands.c (execute_file_commands): Call notice_finished_file to
+ set FILE's status correctly when start_job fails (because it's out

+
+ * Version 3.20.

+ that at some point will be fixed--er, enhanced to alleviate this

+
+ * make.texinfo (Commands: Execution): Documented new competing for

+ this one the broken pipe so they won't compete; if this is the only
+ one, give it the good standard input.
+
+ * make.h: Declare notice_finished_file.
+
+ * commands.c (execute_file_commands): Use noticed_finished_file
+ after waiting for the child when there is only one job slot.
+
+ * remake.c (notice_finished_file): New function to re-check mtime's

+ (update_file_1): Use notice_finished_file.
+
+ * commands.c (child_handler, execute_file_commands): Use new
+ variable `job_slots_used' to record the number of jobs currently
+ running, rather than diddling with `job_slots'.
+ (execute_file_commands): Increment `job_slots_used' before calling
+ start_job and decrement it on failure to avoid race condition.
+ If there is only one job slot, wait for the child to finish and
+ return its status so commands are run in linear order, as if there

+
+ * file.h (struct file): Add `dontcare' member.
+
+ * read.c (read_all_makefiles): When no default makefiles are found,
+ put the names of all those tried in the `read_makefiles' chain so

+ `changed' members the value of 0 so we won't care if they cannot be
+ found or remade.
+
+ * make.texinfo (Makefiles: Remaking Makefiles): Documented that
+ default makefiles will be remade if not found.
+
+ * read.c (read_all_makefiles): If no default makefiles can be found,

+
+ * read.c (read_makefile): Don't check for FILENAME being "-".

+ * make.c (main): For each `-f' flag with arg `-' (standard input),
+ read standard input into a temp file and pass the temp file's name
+ to read_all_makefiles, after making sure it will not be remade.

+ for a normal makefile, 1 for MAKEFILES variable or 2 for an included

+
+ * make.h, rule.c (displace_pattern_rules,
+ add_displaced_pattern_rules): Removed these functions.

+ (start_job): Set `environ' to the child's `environ' member before
+ exec'ing the command.

+
+ * commands.c (child_handler): Print out the "*** ..." error message

+
+ * make.h, make.c: Remove construct_argv function.

+Fri Sep 23 16:52:27 1988 Roland McGrath (mcgrath at helen.Berkeley.EDU)
+
+ * remake.c (update_file_1): Don't return if FILE's state is
+ `cs_deps_running'. In that case, we need to run through and check
+ the states of all our dependencies.
+
+ * commands.c (execute_file_commands): Decrement `job_slots' after
+ starting a new job to run file commands.
+
+ * commands.c (start_job): Made it set the state to `cs_running'.
+
+ * make.c (main): Fixed usage of `g', `lastgoal', and `goals' in the
+ goal-making loop.
+
+ * commands.c (child_handler): When commands finish, set the
+ corresponding file's `update_status' and `updated' flags as
+ appropriate, and reset the modtimes of the file and any `also_make'
+ files it has.
+
+ * remake.c (remake_file): Don't re-set `last_mtime' and set `updated'.
+
+ * commands.c (fatal_error_signal): Don't swallow all the children
+ with a loop around `wait ((union wait *) 0)'!!!

+ * make.c (struct command_switch): Added `positive_int' type.
+ (switches): Added -j (job_slots).
+ (construct_makeflags, decode_switches, decode_env_switches):
+ Handle`positive_int'-type switches.
+
+ * glob.c (glob_vector): Rename local variable `vector' to `VeCtOr'.
+ This is said to avoid a conflict with some system's global `vector'
+ variable.
+
+ * variable.c (expand_function): Made the `shell' function use
+ construct_command_argv and do its own child control and piping.
+
+ * make.c (main): Turn standard input into a broken pipe after
+ reading in all makefiles (the last time it will be needed).
+
+ * commands.c (struct child): Remove `pipe_fd' member. We don't use
+ pipes any more.
+ (start_job): Return 0 for success, 1 or failure (rather than void).
+ Don't use pipes. Don't turn the child's stdin into a broken pipe.
+ (child_handler): Print "*** Error" messages when necessary.
+ Die on failed commands when -k was not given.
+ (execute_file_commands): Check the return of start_job and remove
+ the child from the chain and return failure if it is nonzero.
+
+ * make.c (die): New function to clean up and exit.
+ (fatal, pfatal_with_name): Use die.
+
+Thu Sep 22 14:27:11 1988 Roland McGrath (mcgrath at helen.Berkeley.EDU)
+
+ * commands.c (struct child): Added `commands', `pipe_fd', and
+ `noerror' members to keep track of info about a command thread.
+ (start_job): New function to start a job and update the argument
+ `struct child' to reflect its status.
+ (execute_file_commands): Merged run_file_commands back in.
+ Made it use new start_job function.
+
+ * rule.c (freerule): Don't free the `struct commands' of the
+ discarded rule. It may be used in more than one place.
+
+ * commands.c (execute_command_line): Made it not try to delete the
+ possibly partly-made file. The child_handler function will do this.
+ (fatal_error_signal): Ditto + call kill_children.
+
+ * make.h: Declare job_slots.
+
+ * make.c (main): Collect goals in a dep chain and run through this
+ chain waiting for a child, eliminating finished goals, updating all
+ remaining goals, and quitting if they fail and not -k.

+ * commands.c (child_handler): If called with SIG < 0, - SIG is the
+ max number of children to bury.
+
+ * commands.c (child_handler): If called with SIG as zero,
+ block waiting for running children.

+
+ * remake.c (update_file_1): Use the `command_state' member of FILE
+ and its dependencies to determine what commands are running, what to
+ do, etc. If commands or dep commands are running when we are
+ called, return success (0). If commands finished since the last
+ time we were called, return their status.
+
+ * commands.h: Declare kill_children.
+
+ * commands.c: Define `struct child' to keep track of child
+ processes, with the chain in `children'.
+ (child_handler): New function to catch child-termination signals
+ (SIGCHLD, or SIGCLD for USG), store the returned status in the
+ appropriate structure, take the now-obsolete `struct child' out of
+ the chain, and free its storage.
+ (execute_file_commands): Put all of the stuff invloving running the
+ commands into new function run_file_commands. Execute_file_commands
+ now does process management for the commands, while
+ run_file_commands (which is run in a subprocess) runs the commands.
+ (kill_children): New function to kill all running children by
+ sending them signal SIG. If there are any children still living
+ after they are all sent SIG, they are all sent SIGKILL.
+
+ * make.c (main): Catch SIGCHLD (SIGCLD for USG) with child_handler.
+
+ * commands.h: Declare child_handler function.
+
+ * commands.c (execute_file_commands): Check the `command_state'
+ member of FILE and return 0 if it is `cs_running' or
+ `cs_deps_running' and return the stored status if it is `cs_finished'.
+
+ * file.h (struct file): Added `command_state' member.
+
+ * commands.c (execute_command_line): Add `$' to the list of
+ characters special to the shell.

+ build_vpath_lists to read_all_makefiles.
+
+ * read.c (read_all_makefiles): Install the default pattern rules

+ * make.h: Declare displace_pattern_rules and
+ add_displaced_pattern_rules.
+
+ * rule.c (displace_pattern_rules, add_displaced_pattern_rules): New
+ functions to stow the chain and add the stowed chain on the end of

+ to vpath_search.
+
+ * vpath.c (vpath_search, selective_vpath_search): Removed unused
+ DIRPREFIX and DPLEN args.
+
+ * read.c (read_makefile): Also turn off -n when updating makefiles.
+
+Tue Sep 20 17:01:10 1988 Roland McGrath (mcgrath at pepper.Berkeley.EDU)
+
+ * Makefile: Put tags files in the tarfile.
+
+ * read.c (read_makefile): Get the modtime of the makefile via a stat
+ call so that a later file_mtime call won't do VPATH search for it.
+
+ * read.c (read_makefile): Don't turn off -t and -q if the makefile
+ was a command-line target.
+
+ * make.c (main): Enter command-line targets as files and set their
+ `cmd_target' members.
+
+ * file.h (struct file): Added `cmd_target' member.
+
+ * read.c (read_makefile): Temporarily turn off -t and -q while
+ updating makefiles.
+
+ * make.c (main): Don't use arg 0 from other_args (which is now
+ argv[0]; i.e., the program's name).
+
+ * read.c (read_makefile): Only return nonzero if commands were
+ actually run to remake the makefile.
+
+ * remake.c (update_file_1): Set FILE->updated to -1 if no commands
+ were actually run (because no update was done or -t was given).
+
+ * make.c (decode_switches): Fixed bug wherein xrealloc was passed
+ bad args if it tried to expand other_args->list.
+
+ * read.c (read_all_makefiles): Made it not look at the `MAKE'
+ variable, just use argv[0].

+Sun Sep 18 17:34:11 1988 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * read.c (rerun_make): New function to re-exec make.
+
+ * make.c (construct_makeflags, construct_argv): New functions to
+ construct the `MAKEFLAGS' variable and to construct an arg list from
+ parsed info.
+
+ * read.c (read_makefile): New arg UPDATEIT, if nonzero, says to
+ update the makefile as a target before reading it in. When reading
+ included makefiles, pass this as zero. Now returns nonzero if the
+ makefile was updated, zero if not.
+ (read_all_makefiles): Pass a nonzero UPDATEIT arg to read_makefile
+ for all default and -f makefiles and all makefiles from the
+ `MAKEFILES' variable. If any of the makefiles has changed, re-exec
+ self to re-read them.
+

+ under -p.
+
+ * commands.c (execute_file_commands): Allocate one byte for each of

+ the `struct file'.
+
+ * read.c (record_files): If commands were specified twice, the error
+ message specifies in what files and at what line numbers.
+
+ * make.c (main): If any of the signals we usually fatal on were
+ ignored by the parent (probably a shell), ignore them.
+
+ * make.c (main): Print version info for -v, -p, or -d.
+ (print_data_base): Don't print version info. It will be done in main.

+
+ * file.c: Increased number of hash buckets to 1007.
+
+ * rule.c (count_implicit_rule_limits): Moved comptation of

+ `maxsuffix', and must be called before count_implicit_rule_limits.
+
+ * rule.c (pattern_search): If an existent (non-intermediate)
+ dependendency was found via a terminal rule, set its
+ `tried_implicit' flag, so it will never have implicit rule search done.

+ * arscan.c: USG and Sun386i fixes.
+

+ gets filled in with a malloc'd buffer containing the piped stdout of
+ the command.
+ (execute_file_commands): Use above (pass nil).
+
+Mon Sep 5 17:03:49 1988 Roland McGrath (mcgrath at hecuba.Berkeley.EDU)
+
+ * Makefile: Added copyright notice.

+
+Sat Sep 3 18:09:39 1988 Roland McGrath (mcgrath at homer.Berkeley.EDU)

+
+ * vpath.c (build_vpath_lists): Made it recursively expand the

+
+ * rule.c (count_implicit_rule_limits): Made it not crash if a

+
+Sun Aug 28 15:51:12 1988 Roland McGrath (mcgrath at homer.Berkeley.EDU)
+
+ * make.texinfo: Clarified that the arg to the `origin' function is a

+
+Sat Aug 13 14:20:46 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * make.c (decode_switches, main): Made the command switches be

+
+Wed Aug 10 00:55:39 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * variable.c (print_variable_data_base): Fixed bug which made -p
+ dump core. (This was a really idiotic bug.)
+
+ * rule.c (pattern_search): Fixed a bug which made it make the
+ `also_make' member of the file in question nil if the first of
+ the successful rule's targets was the matching one.
+ Made it use only as much storage as necessary in the `also_make'
+ member.
+ (create_pattern): Made it use only as much storage as necessary in
+ the `lens' and `suffixes' members of the created rule.
+
+ * remake.c (library_file_mtime): Made it `static'.
+
+ * file.c: Added a declaration for `errno', which is declared in some
+ <errno.h>'s, but not all.
+
+ * file.h (struct file): Added `also_make' member for multiple-target
+ implicit rules.
+ * rule.c (pattern_search): Made it put the names of files updated by

+ was no space before the = or :=.
+
+ * make.texinfo (Features): Made the changes which were made in RCS
+ revision 2.7 but somehow lost since then. Added -W.

+ * make.c (decode_switches, main): Added the -W flag to give files a
+ time-stamp of now, for a `what if' effect when used with -n.
+
+ * commands.c (print_commands): Made it say `(built-in)' for commands
+ that are built into the default ruleset.
+
+ * read.c (record_file): Made .SUFFIXES get its deps frontwards (again).
+ * rule.c (set_default_suffixes, convert_to_pattern): Made it read
+ .SUFFIXES's deps frontwards, so the converted rules will not be in
+ reverse order.
+
+ * rule.c (new_pattern_rule): Fixed a bug wherein it would keep
+ searching after it had removed a matching rule and ended up diddling
+ with freed storage.
+
+ * rule.c (freerule): Made it take the given rule off the chain.
+ (new_pattern_rule, count_implicit_rule_limits): Use freerule to
+ remove rules from the chain.
+
+ * vpath.c (construct_vpath_list): Made it return after cleaning out
+ all previous searchpaths when given a nil DIRPATH arg, so it won't
+ go into the construction code and dump core dereferencing a nil
+ pointer.
+
+ * variable.c (patsubst_expand): Fixed a bug which made it not match
+ correctly and sometimes dump core.
+
+Mon Aug 8 16:35:48 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * rule.c (default_suffix_rules): Made the .texinfo.dvi rule remove

+
+ * make.texinfo (Top): Changed `last updated' date to be correct (for

+
+Sat Aug 6 19:51:10 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * commands.c (print_commands): Added this function to print the

+ * rule.c (print_rule_data_base): Use above.
+ * file.c (print_file_data_base): Ditto.

+ matching pattern's target is used to give deps and commands.
+
+Fri Aug 5 18:00:29 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * rule.c (struct rule): Changed name, namelen, and patsuffix members
+ to targets, lens, and suffixes, which are arrays, for multiple targets.
+ (create_pattern_rule): Now takes first arg TARGETS, a nil-terminated
+ array of targets, rather than a single target and patsuffix pointer.
+
+ * read.c (record_files): If it finds an implicit pattern rule, it
+ collects all the targets into an array and passes the whole thing to
+ create_pattern_rule. If there are non-pattern targets, it is a
+ fatal error.
+
+Tue Aug 2 15:06:38 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * make.c (readline): Split backslash-newline checking from reading
+ and buffer-expanding.
+ (getline): Created to do the reading and buffer-expanding formerly
+ done in readline.
+
+ * rule.c (pattern_search): Made it reject nonterminal match-anything
+ rules when a specific rule has matched, rather than rejecting
+ terminal match-anything rules in this case.
+
+ * rule.c (convert_to_pattern): Fixed a bug caused when the change to
+ make it only recognize two-suffix rules whose target suffixes
+ precede their dependency suffixes which made it work in the opposite
+ direction (even worse than it started out).
+
+ * rule.c (pattern_search): Made it reject nonterminal match-anything
+ rules as intermediate targets when searching for both real and
+ intermediate dependencies, rather than only when searching for
+ intermediate ones.
+
+Sun Jul 31 00:33:56 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * rule.c (convert_to_pattern): Made it only recognize two-suffix

+ variables be defined with origin `o_automatic'.
+
+ * variable.h: Added `o_automatic' to `enum variable_origin'
+
+ * file.c (remove_intermediates): Made it not print an error message
+ if the error was that the file does not exist.
+
+ * rule.c: Removed `recursive' member from `struct rule'.
+
+ * remake.c (library_file_mtime): Made it not use the directory hash
+ functions, as reading in and hashing /usr/lib and /lib is slow and
+ most likely unnecessary.
+
+ * remake.c (remake_file): Changed message from ``No specification
+ for making'' to ``No way to make'' so it will be short enough that
+ most filenames will fit on a line.
+ Made it look at the `recursive' member of the `struct commands',
+ rather than of the `struct file' (which no longer has one).
+
+ * commands.c (execute_file_commands): Made it look at the
+ `recursive' member of the `struct commands', rather than of the
+ `struct file' (which no longer has one).
+
+ * file.h: Removed `recursive' member from `struct file'.
+
+ * commands.h: Added `recursive' member to `struct commands'.
+
+ * dep.h: Removed unused `quotedparen' member from `struct nameseq'
+ and `struct dep'.
+
+ * read.c (dequote): Removed this function.
+ (multi_glob): Removed reference to `quotedparen' member of
+ a `struct nameseq' and calls to dequote.
+

+ pattern rules, not just those with commands given at that time.
+ Removed check for recursive commands.
+ Made it check for pairs of .SUFFIXES dependencies to reject as
+ default goals as well as single ones (that don't start with dots).
+ (read_makefile): Added checks for recursive commands to set
+ the `recursive' flag in the `struct commands'.
+
+Sat Jul 30 15:47:23 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * make.c (find_next_token): Made the LENGTHPTR arg optionally nil.
+
+ * make.c: Removed `files_made' variable which is defined static in

+ non-fatal error.
+ (decode_env_switches): Made LEN arg unsigned. Cleaned up.
+ (print_version): Made it say ``see the source'' rather than ``see
+ the source file'', since there is more than one.
+
+ * file.h: Made `num_intermediates' declared unsigned.
+
+ * file.c: Made `num_intermediates' variable unsigned.
+ (remove_intermediates): Removed unused FORMAT arg.
+ (enter_file): Made it handle double-colon files properly, adding the
+ new entry as the old entry's prev pointer.
+
+ * dir.c: Re-indented the `struct dir' definition to be right.
+ (dir_load): Cleaned up slighty.
+ (file_exists_p): Removed comment saying we could use `access', since
+ that is a bad idea (except for setuid programs). Cleaned up slightly.
+
+ * commands.c: Changed some comments slightly.
+ (execute_file_commands): Cleaned up a bit. Changed some comments,
+ added others. Moved freeing of storage for $^ and $? to the same
+ place as for the other automatic variables.
+ (execute_command_line): Made `#' trigger a shell.
+ Added some comments. Cleaned up a bit. Put all the special chars
+ that trigger shells into an array easily changeable at the top.
+
+ * ar.c: Added comments explaining each function.
+ (ar_scan_1): Merged into ar_member_date.
+ (ar_member_date): Changed call to ar_scan_1 to the body of that
+ function.
+ (ar_member_date_1): Simplified to a ?: expression rather than an
+ if-else statement.
+ (ar_member_touch): Changed error handling around a bit.
+ None of these errors are fatal now.
+
+ * variable.c (subst_expand): Added a new arg BY_WORD, to do substs
+ only on full words.
+ (patsubst_expand): Fixed bug which made calls whose patterns
+ contained no `%' to not work correctly, by using above.
+ (variable_expand): Pass extra arg to `subst_expand'.
+
+ * variable.c (expand_function): Fixed bug which made `foreach' calls
+ with one-word lists run off into never-never land.
+
+Fri Jul 29 20:12:36 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * variable.c (expand_function): Made a very minor speed improvement
+ by avoiding an unnecessary strlen call.
+
+Wed Jul 27 16:01:47 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * rule.c (default_suffixes): Rearranged the list somewhat; added
+ `.el' and `.elc' to speed things up (especially when building
+ Emacs), for the same reason `.h' is there.
+
+ * read.c (record_files): Changed `lineno' from `long' to
+ `unsigned int'.
+
+Sun Jul 24 02:15:30 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * variable.c (expand_function): Eliminated use of `wstok'
+ because it is non-reentrant and unreliable.
+ Fixed a minor bug which would cause something not to be freed.
+ * make.c (wstok): Removed `wstok' because it is no longer used.
+
+ * variable.c (expand_function): Made `foreach' function put
+ spaces between output texts like it's supposed to.
+
+Sat Jul 23 17:32:55 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * rule.c (default_suffixes, default_suffix_rules): Added rule
+ to make %.dvi from %.texinfo.
+
+ * dir.c (print_dir_data_base): Made it say a bit more.
+
+Fri Jul 22 23:13:16 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * make.c (print_data_base): Split this function up into one
+ for each thing.
+ * variable.c (print_variable_data_base): One of the above.
+ * rule.c (print_rule_data_base): Ditto.
+ * file.c (print_file_data_base): Ditto.
+ * dir.c (print_dir_data_base): Ditto.
+
+ * rule.c (install_pattern_rule): Fixed a bug which caused the
+ terminal and recursive flags to always be zero for rules
+ entered by this function.
+
+ * make.texinfo (Rules: Double-colon): Added a paragraph
+ explaining the purpose of double-colon rules.
+
+ * make.texinfo (Implicit: Catalogue of Rules): Updated to
+ reflect new C++, TeX, Web, and Texinfo rules. Other slight
+ editorial changes.
+
+ * commands.c (execute_file_commands): Fixed a bug wherein
+ random memory could get written for files with no deps.
+
+Wed Jul 20 19:30:31 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * read.c (readline): Fix bug wherein it would not recognize a
+ backslash-newline if the buffer filled up and was enlarged
+ right before reading the newline.
+
+Tue Jul 19 19:55:02 1988 Roland McGrath (mcgrath at chilli.Berkeley.EDU)
+
+ * read.c: Added default suffix rules for .cc (using $(C++),
+ which defaults to `g++', and $(C++FLAGS)), .tex, .dvi, .web
+ and .cweb (using $(TEX), $(WEAVE), $(TANGLE), $(CWEAVE) and
+ $(CTANGLE)).
+
+Sat Jul 16 21:24:28 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * Made error formats use %u rather than %ld for line numbers,
+ which are now unsigned int's rather than long's.
+
+ * read.c (conditional_line): Fixed some bugs caused by use of
+ unsigned int rather than int in one place.
+
+ * read.c (conditional_line): Put the info about active
+ conditionals in a struct.
+ (read_makefile): Make a new struct of info about conditionals
+ for included makefiles and restore the old one after the
+ included makefile has been read.
+
+ * read.c (read_makefile): Don't try to read a makefile with
+ name "" after giving an error message because an `include'
+ directive gave no filename.
+
+ * read.c (read_makefile): Give an error message for
+ non-whitespace text after the filename in an `include' directive.
+
+ * make.c (error): Take five args, like `fatal'. It managed to
+ lose with only two. Is there a better way to do this without vfprintf?
+
+ * read.c (read_makefile): Commands consisting of only
+ whitespace are not the same as no commands. I thought I'd
+ fixed this bug months ago; it seems to have come back.
+
+ * make.c (collapse_continuations): All whitespace around a
+ backslash-newline combination is turned into a single space.
+
+ * Added COPYING file and copyright notices to all files.
+
+ * make.texinfo (Running: Goals): Fix a typo.
+
+ * read.c (do_define): Take an arg for the origin of the
+ variable being defined.
+ (read_makefile): Grok `override define'.
+
+ * make.texinfo (Variables: Override Directive, Defining):
+ Document the `override define' combination directive.
+
+ * ar.c (ar_member_date): Make a 0 return from `ar_scan' return
+ (time_t) -1 (nonexistent file), rather than (time_t) 0, which,
+ when put in the `struct file', makes `file_mtime' try to get
+ the mtime over and over again.
+
+ * variable.c (pattern_matches): Fix a bug that made patterns
+ not beginning with `%' never match.
+
+Fri Jul 15 21:01:44 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * Took Make out of RCS.
+
+ * Split the monolithic `make.c' into several smaller files.
