Construct it over again, since the former may have been freed already. Thu Dec 13 17:21:03 1990 Roland McGrath (roland at churchy.ai.mit.edu) * make.h [__GNU_LIBRARY__]: Include to get random fn decls. Wed Dec 12 17:12:59 1990 Roland McGrath (roland at churchy.ai.mit.edu) * make.h, arscan.c, glob.c: Only include #ifdef USG. * variable.c (define_variable_in_set): Replace env_overrides check that wasn't really redundant (undoing Sep 28 change).

Use to declare misc fns rather than explicit decls. [_POSIX_SOURCE]: Don't declare kill ( will). Include before because some braindead nonconformant 1003.1 implementation needs it. * misc.c: Don't declare malloc, realloc. Do it in make.h. * arscan.c, glob.c: Use sequence for string fns from make.h verbatim. * make.h (S_ISDIR, S_ISREG): Declare if necessary. * commands.c (delete_child_targets), job.c (search_path), read.c (construct_include_path): Use S_ISfoo(m) instead of (m & S_IFMT) == S_IFfoo. * dir.c, glob.c [_POSIX_SOURCE]: Use dirent.

Tue Oct 23 19:34:33 1990 Roland McGrath (roland at churchy.ai.mit.edu) * main.c (define_makeflags): When there are no flags to write, make sure the array has two leading nulls, since `MAKEFLAGS' is defined from &flags[1]. * main.c (default_keep_going_flag): New variable (constant one). (command_switches: -k, -S): Use above for default value. (define_makeflags): Only write flag/flag_off switches if they are on, and either there is no default value, or they are not the default. Mon Oct 22 16:14:44 1990 Roland McGrath (roland at churchy.ai.mit.edu) * main.c (struct command_switch): New member `no_makefile'. (command_switches: -n, -q, -t): Set no_makefile == 1. (define_makeflags): Take new arg MAKEFILE: if nonzero, don't use options whose `no_makefile' flags are set. (main): Call define_makeflags with MAKEFILE==1 before remaking makefiles, and again with MAKEFILE==0 before remaking goals. Tue Oct 2 17:16:45 1990 Roland McGrath (roland at geech.ai.mit.edu) * Version 3.58.12. Mon Oct 1 15:43:23 1990 Roland McGrath (roland at churchy.ai.mit.edu) * arscan.c [HPUX]: Use PORTAR==1 format. Sat Sep 29 16:38:05 1990 Roland McGrath (roland at churchy.ai.mit.edu) * make.h, remake.c, arscan.c: Don't declare `open'. Fri Sep 28 04:46:23 1990 Roland McGrath (roland at churchy.ai.mit.edu) * variable.c (define_variable_in_set): Remove redundant -e check. Wed Sep 26 00:28:59 1990 Roland McGrath (roland at geech.ai.mit.edu) * job.c (start_job): Set RECURSIVE from the right elt of CHILD->file->cmds->lines_recurse. * 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 variable-expanded command lines. * job.c (new_job): Store expanded command lines in `command_lines' member of new child. Don't clobber FILE->cmds. (start_job): Use CHILD->command_lines in place of CHILD->file->cmds->command_lines. * variable.h, variable.c, job.c, expand.c: Undo yesterday's change, which is no longer necessary since we have cleverly avoided the issue. * job.c (start_job): Don't variable-expand each command line. (new_job): Do them all here, storing the expansions in the array. Tue Sep 18 01:23:13 1990 Roland McGrath (roland at churchy.ai.mit.edu) * variable.h (struct variable): Remove `expanding' member. * variable.c (define_variable_in_set): Don't initialize it. * expand.c (struct variable_expanding): New type, a linked list containing `struct variable' pointers. (variables_expanding): New variable, the chain of variables currently 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. * make.h: Put it here instead. * variable.c (target_environment): If `.NOEXPORT' was specified as a target, only export command-line and environment variables, and file-origin variables that were in the original environment. * make.man: Add missing ?roff control for `-I' option description. Thu Sep 13 14:10:02 1990 Roland McGrath (roland at churchy.ai.mit.edu) * load.c [UMAX]: Move #include to [not UMAX_43]. Wed Sep 12 15:10:15 1990 Roland McGrath (roland at churchy.ai.mit.edu) * expand.c (recursively_expand): Don't use `reading_filename' and `reading_lineno_ptr' if they're nil. Thu Aug 30 17:32:50 1990 Roland McGrath (roland at geech) * Version 3.58.10. Tue Aug 28 04:06:29 1990 Roland McGrath (roland at churchy.ai.mit.edu) * 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 NAME is not the same length. Sat Aug 25 16:17:14 1990 Roland McGrath (roland at geech) * job.c (construct_command_argv_internal): Use a static char array for a constant, since old C has no auto aggregate initializers. Thu Aug 23 16:11:03 1990 Roland McGrath (roland at churchy.ai.mit.edu) * job.c (search_path): If PATH is nil or "" use a default path. Wed Aug 22 01:05:32 1990 Roland McGrath (roland at churchy.ai.mit.edu) * Version 3.58.9. * job.c (exec_command): Don't take PATH and SHELL args. Get them from ENVP. (child_execute_job): Don't take FILE arg, and don't pass path and shell to exec_command. (start_job): Don't pass FILE arg to child_execute_job. * function.c (expand_function: `shell'): Ditto. * 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) * read.c (multi_glob): For ~USER/FILE, if USER isn't found, don't change the file name at all. Tue Aug 7 18:33:28 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * function.c (expand_function: `suffix'/`notdir'): Don't kill the last space if we never wrote one. * function.c (expand_function: `suffix'): Retain the dot, like the documentation says. 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 push_signals_blocked_p (0). * main.c (fatal_signal_mask): New variable, mask of signals caught with fatal_error_signal. (main): Set it. * job.c ({block,unblock}_children): Renamed to {block,unblock}_signals. 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. Thu Aug 2 22:41:06 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU) * main.c, function.c: Fixed typos in comments. * file.c (print_file_data_base): Fix computation of avg files/bucket. Tue Jul 31 22:11:14 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU) * Version 3.58.7. Wed Jul 25 16:32:38 1990 Roland McGrath (mcgrath at tully.Berkeley.EDU) * arscan.c (ar_name_equal): Fixed to really do it right.

Accounts for a possible trailing slash in MEM. * remake.c (f_mtime): Keep track of whether ARNAME is used and free it if not. Also free MEMNAME. * ar.c (ar_member_date, ar_touch): Ditto. * arscan.c (arscan) [HPUX or hpux]: Treat same as USGr3 PORTAR==1. * make.h: If NSIG is not defined, but _NSIG is, #define NSIG _NSIG. * compatMakefile: Don't use $* in explicit rules. * default.c (default_variables: "PREPROCESS.S"): Include $(CPPFLAGS). * remake.c (f_mtime): If FILE is an ar ref, get the member modtime. * function.c (string_glob): Terminate the string properly when it's empty. Wed Jul 18 11:26:56 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU) * Version 3.58.6. * commands.c (set_file_variables): Fixed computation for ^F/?F elt len. 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 ret value casts to (void *) #ifdef __STDC__ to avoid conflicts btwn ANSI and BSD `signal' and handler types. * main.c (main), job.c (child_handler): Use it. Fri Jul 6 00:00:38 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * ar.c (ar_member_date, ar_touch): Pass 2nd arg to f_mtime. * read.c (read_makefile): Search the include path for MAKEFILES variable makefiles (TYPE == 1), like it says in the manual. * 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. * make.h: Declare uniquize_deps. * main.c (main): Remove unused variable. (decode_switches): Remove unused label. * remake.c: Include "ar.h" for ar_parse_name decl. * implicit.c (try_implicit_rule): Remove unused variable. * function.c (expand_function: `shell'): Declare fork, pipe. * 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. * remake.c (f_mtime): After doing rename_file, do check_renamed instead 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. Wed Jul 4 04:11:55 1990 Roland McGrath (mcgrath at helen.Berkeley.EDU) * remake.c (update_goal_chain): Do check_renamed after calling file_mtime. (check_dep): Ditto after update_file. * 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. * function.c (string_glob): Don't leave a trailing space. * read.c (do_define): Allow leading whitespace before `endef'. 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. Sat Jun 30 00:53:38 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * ar.c (ar_member_date): Don't free ARNAME since enter_file holds onto the storage. * 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'. (default_suffix_rules): Define .S.o rule. * 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) * Version 3.58.4. Fri Jun 15 21:12:10 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU) * glob.c: New version from ai-lab which doesn't do [^abc]. 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 . __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 next command line. * 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. 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 this code got lost. * implicit.c (pattern_search): Use the right index variable when seeing if we need to expand FILE->also_make. Sun Mar 4 09:18:58 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * Version 3.58.0. * remake.c (remake_file): Treat non-targets without commands under -t the same as anything else without commands. Sat Feb 24 17:46:04 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * default.c (default_variables: PREPROCESS.S): Removed $< from defn. * main.c (main): Ignore arguments that are the empty string, rather than feeding them to enter_file and barfing therein. Wed Feb 14 16:28:37 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * main.c (main): Call construct_include_path after doing chdirs. Thu Feb 8 13:43:44 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * Version 3.58. Sat Feb 3 22:06:55 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * Version 3.57.7. * make.texinfo (Implicit: Catalogue of Rules): For RCS, noted that working files are never overwritten by the default rule. Thu Feb 1 17:27:54 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * rule.c (count_implicit_rule_limits): Redid loop control to not run twice on freed rules. * GNUmakefile: Made `.dep' files be architecture-specific too. * main.c (main, log_working_directory) [USG]: Block children around calls to `getwd' (actually `getcwd' on USG), because that function sometimes spawns a child running /bin/pwd on USG. Tue Jan 30 14:02:50 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * function.c (subst_expand): Pay attention to SUFFIX_ONLY, putz. Wed Jan 24 21:03:29 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * make.man: Fixed repeated word. * make.texinfo (Missing): Reworded a buggy sentence. Mon Jan 22 12:39:22 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * main.c (print_version): Added 1990 to copyright notice. * Version 3.57.6. Sat Jan 20 11:52:01 1990 Roland McGrath (mcgrath at homer.Berkeley.EDU) * file.c (rename_file): Don't free the storage for the old name, since it might not have been malloc'd. * job.c (construct_command_argv): Call allocated_variable_expand_for_file instead of variable_expand_for_file to expand `$(SHELL)'. * make.texinfo (Bugs): Change address from roland@wheaties.ai.mit.edu to roland@prep.ai.mit.edu. Tue Jan 16 19:22:33 1990 Roland McGrath (mcgrath at tully.Berkeley.EDU) * Version 3.57.5. Sun Jan 14 16:48:01 1990 Roland McGrath (mcgrath at helen.Berkeley.EDU) * job.c (start_job): Only call wait_to_start_job for the first command line in each sequence. Thu Jan 4 14:27:20 1990 Roland McGrath (mcgrath at helen.Berkeley.EDU) * load.c [LDAV_BASED] (wait_to_start_job): Loop while job_slots_used > 0, not > 1. * job.c (search_path): Don't return a pointer to local storage. Allocate data space for the pathname instead. * function.c (expand_function: `shell'): Don't write garbage if the child wrote no output. Wed Jan 3 15:28:30 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU) * Version 3.57.4. * file.h (struct file): New member `renamed', a `struct file *' that is the place this file has been renamed to (or nil). (check_renamed): Macro to check for a file having been renamed. Dereferences the renaming and sets the given variable. * file.c (rename_file): Completely rewritten. Renames in place if possible, or moves FILE to a different hash bucket if there is no existing file with the new name. If there is an existing file with the new name, FILE is merged into it and FILE->renamed is set to point to 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. * variable.h: Declare merge_variable_set_lists. * remake.c (update_file_1, check_dep): Run `check_renamed' after calling file_mtime, check_dep. (update_file): Same after update_file_1. (update_goal_chain, update_file_1, check_dep): Same after update_file. * read.c (uniquize_deps): New fn, broken out of record_files, to remove duplicate deps from a chain. (record_files): Use it. * implicit.c (pattern_search): Use uniquize_deps. * file.h (file_mtime_1): New macro, like file_mtime, but take second arg, passed to f_mtime. (file_mtime): Implement as file_mtime_1 (file, 1). (file_mtime_no_search): New macro: file_mtime (file, 0). * remake.c (f_mtime): Take new arg SEARCH. Only do VPATH and `-lNAME' searching if it is nonzero. * main.c (main): Use file_mtime_no_search for makefiles. * remake.c (update_goal_chain): Use file_mtime_no_search if MAKEFILES. * main.c (printed_version): New variable, init'd to zero. (print_version): Set it to nonzero before returning. (die): If -v and !printed_version, call print_version before clean up and death. * main.c (log_working_directory): Keep track of whether or not the "Entering" message has been printed, and return without printing the "Leaving" message if not. * main.c (decode_switches): Don't complain about missing args before checking for a noarg_value elt in the command_switch structure.

(Variables: Advanced: Substitution Refs): When pxref'ing about `patsubst', use node `Text Functions', not `Functions'. Add an xref about `patsubst' after description of $(var:a%b=c%d). (Functions: Syntax of Functions): Explain why mixing delimiters in function/var refs is unwise. Clarify fn arg evaluation order. (Options): Reworded sentence about `-e'. (Implicit: Implicit Variables): Don't say `RM' is unused. Say the dflt values for the flag vars is empty unless otherwise noted, since some have defaults. (Implicit: Pattern Rules: Pattern Examples): Clarified use of $< and $@ in first example. (Implicit: Last Resort): Don't say the .DEFAULT example creates files "silently". It's automatic, but not silent. (Implicit: Search Algorithm): Fixed confusing ungrammatical sentence for item 5.1. (Archives: Archive Update): Added missing `next' pointer. (Archives: Archive Symbols): Note that GNU `ar' deals with this automatically. * job.c (search_path): New fn, to search for an executable file in a search path (broken out of exec_command). (exec_command): Take fourth arg, the shell program to use (if necessary). Use search_path for the program, and the shell program. Pass args "file args ..." to shell program (with no -c), where FILE is the full pathname of the program (script) to be run. (child_execute_job): Pass shell program to exec_command. * main.c (main): Ditto. * main.c (main): Don't write a message if exec_command returns, because it will never return. Fri Dec 22 16:19:58 1989 Roland McGrath (mcgrath at hecuba.Berkeley.EDU) * default.c (default_variables: "LINK.cc"): Use $(C++FLAGS) instead of $(CFLAGS). Wed Dec 20 09:58:48 1989 Roland McGrath (mcgrath at hecuba.Berkeley.EDU) * job.c (new_job): If start_job set the child's `command_state' to `cs_finished', call notice_finished_file. Sun Dec 17 19:45:41 1989 Roland McGrath (mcgrath at hecuba.Berkeley.EDU) * Version 3.57.3.

Thu Nov 30 15:47:13 1989 Roland McGrath (mcgrath at homer.Berkeley.EDU) * Version 3.57.2. * function.c (expand_function: `shell'): Don't clobber BUFFER and then try to free it. * remake.c (update_file_1): Took code to force remake of nonexistent deps out of #if 0, and changed the test to nonexistent non-intermediate deps. In version 4, I think removing this test completely will implement the new feature that if a: b and b: c and c is newer than a, b need not be remade. Sun Nov 26 16:12:41 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * compatMakefile (load.o, remote.o): Use $*.c instead of explicit file names so that using VPATH works. Tue Nov 21 14:57:18 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * Version 3.57.1. Fri Nov 10 03:28:40 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * remake.c (check_dep): Set *MUST_MAKE_PTR if FILE does not exist after being updated. (The exact opposite test was here before; why???) (update_file_1): Set a dep's `changed' member after updating it if it is phony and has commands (because they will then always be executed). Thu Nov 9 13:47:12 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * load.c [UMAX]: #ifdef UMAX_43 include different headers for the `inq_stats' call. * compatMakefile (LOAD_AVG): Document UMAX_43. * Version 3.57.0. * commands.c (chop_commands): New function to chop commands into lines. * job.c (new_job): Break that code out, and call chop_commands. * remake.c (remake_file): Call chop_commands before looking at FILE->cmds->any_recurse. * make.texinfo (Running: Goals): Don't say that the default target won't be taken from an included makefile. * remake.c (update_file_1): #if 0 out setting MUST_MAKE if a dep doesn't exist.

(ar_name_equal): New function to compare names, handling truncated member names and special `.o' truncation. (ar_member_pos): Use ar_name_equal. * ar.c (ar_member_date_1): Use ar_name_equal. * Version 3.56.6. * file.h (struct file): Made `update_status' a `short int', and moved it before `command_state' so the bitfields can be packed better. * remake.c (files_remade): Made global. (notice_finished_file): Don't increment files_remade. * job.c (new_job): Do. * job.c (start_job): Don't return a value. Always set CHILD->file->command_state to either cs_running or cs_finished.

We won't get called unless it's cs_not_started. * read.c (read_makefile): Call collapse_line on the variable-expanded rule line after checking for ; and #. * job.c (start_job): When there are no more commands, always return 0. * commands.c (execute_file_commands): Don't put the new child in the `children' chain unless FILE->command_state is cs_running. * read.c (read_makefile): Rewrote ;-handling to only do it once (why did I do it twice??) and to check for a # before the ;. * job.c (start_job): Set CHILD->file->update_status to 0 when we run out of commands. Set it to 1 before returning failure. (child_handler): Don't set C->file->update_status to 0 when start_job returns success and commands are not running. * read.c (read_makefile): If there is a # before the ; for commands, forget the ; and commands. Thu Oct 12 15:48:16 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * job.c (child_execute_job): Pass -c to the shell. Wed Oct 11 18:41:10 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * Version 3.56.5. * main.c (define_makeflags): Cleaned up to keep better track of dashes written, etc. * function.c (expand_function: `shell'): When converting newlines to spaces in output, search with `index' calls rather than a simple loop. * main.c (main): Make sure stdout is line-buffered. * main.c (decode_switches): Always check for missing switch arg. Mon Oct 9 17:17:23 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * Version 3.56.4.

Thu Sep 21 14:28:42 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * main.c (main): Make an array of the mtimes of the makefiles before updating them, and compare their file_mtimes against this later. Don't re-exec if a makefile was successfully updated but didn't change. If a makefile failed to be remade and no longer exists, die. If a makefile failed to be remade, but changed anyway, re-exec. If a makefile failed to be remade, but is unchanged, continue on.

Wed Sep 6 15:23:11 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * default.c (default_terminal_rules {%:: %,v}, {%:: RCS/%,v}): Don't run co if the target exists. * glob.c (glob_match): [!xyz], rather than [^xyz], means none of [xyz]. * glob.c: Misc minor cosmetic changes. Tue Sep 5 14:49:56 1989 Roland McGrath (mcgrath at saffron.Berkeley.EDU) * load.c [LDAV_BASED] (load_average): Check for == -1, rather than < 0 to see if lseek fails. On some systems, `avenrun' is at an offset > (2**31)-1, and lseek succeeds, returning a negative value. Mon Sep 4 11:07:58 1989 Roland McGrath (mcgrath at saffron.Berkeley.EDU) * rule.c (new_pattern_rule): Return `int' instead of `void': nonzero if the passed rule was used, zero if not. (install_pattern_rule): Pay attention to the return from new_pattern_rule, and don't set the rule's `terminal' flag or give it commands unless it's used. (create_pattern_rule): Same idea. * dir.c (find_directory): Removed unused variable. * commands.c (execute_file_commands): Removed unused variable. * read.c (record_files): Don't use NAME after freeing it.

(Also means don't add spaces without checking the size of the buffer.) * remake.c (update_goal_chain): Don't remove makefiles with cmds and no deps from the chain. * main.c (main): Do it here, before calling update_goal_chain. * remake.c (update_goal_chain): When updating fails, change STATUS even if MAKEFILES is set. Also stop remaking when updating fails if not under -k and MAKEFILES is not set. * remake.c (remake_file, update_file_1, notice_finished_file), commands.c (execute_file_commands), make.h, commands.h: The functions remake_file, notice_finished_file, and execute_file_commands no longer return values, and their callers no longer expect values returned. * remake.c (notice_finished_file): Don't set FILE's modtime to now if it is a non-target with no commands. Fri Sep 1 00:04:39 1989 Roland McGrath (mcgrath at saffron.Berkeley.EDU) * read.c (read_all_makefiles): After freeing each element on MAKEFILES, replace it with the name stored in read_makefiles by read_makefile. * remake.c (update_file_1): Don't decide not to remake if FILE has no cmds and no deps actually changed if FILE doesn't have any deps. * file.c (remove_intermediate): Remove precious files that also have the `dontcare' flag set. * remake.c (update_file_1): Don't always remake if FILE has cmds but no deps; only if FILE is double-colon. (I don't know why this should be done for double-colon targets, but that's what Unix make does.) * load.c [LDAV_BASED] (load_average): Write error messages if the various system calls fail. Keep track of if we've failed before. The first time we fail, write a message saying -l won't be enforced. The first time we succeed after having failed, write a message saying -l will be enforced again. * remake.c [USG]: Don't #include * load.c [generic Unix LDAV_BASED]: #include #ifdef USG, else instead. * job.c [USG && !USGr3 && !HAVE_DUP2]: Remove redundant #include and declaration of `errno'. [...] (dup2): Fixed so it won't always lose. * default.c (default_suffix_rules: .texinfo.dvi): Copy, rather than move, the aux and index files, so the TeX run can use them. * compatMakefile: Remove redundant comment. * load.c [generic Unix LDAV_BASED]: Include instead of , since the `struct nlist' declaration in varies more than the one in . (load_average): Use the `n_un.n_name' field of the `struct nlist', since the declaration uses the union. * main.c (main): For the temporary files made for stdin makefiles, set the `intermediate' and `dontcare' flags. * file.c (remove_intermediates): Don't print any messages for files whose `dontcare' flag is set. (The only files that will be intermediate and `dontcare' will be the temporary files made for stdin makefiles.) * job.c (exec_command): Made global. * job.h: Declare it. * main.c (main): Use exec_command when re-execing. * make.h: Declare environ. * make.c: Don't. * job.c (child_execute_job): New function to perform everything done in the child side of a fork (for a job or `shell' function). (start_job): Call it. * job.h: Declare construct_command_argv and child_execute_job. * function.c (expand_function: `shell'): Use child_execute_job. Thu Aug 31 18:42:51 1989 Roland McGrath (mcgrath at saffron.Berkeley.EDU) * function.c (expand_function: `shell'): Remove a trailing newline instead of turning it into a space. * main.c (main): Do init_siglist #ifdef HAVE_SIGLIST. * job.c [WTERMSIG || (USG && !HAVE_SYS_WAIT)]: Test each W* macro separately and define all those that aren't defined. Sat Aug 26 15:13:21 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * ar.c (ar_name): Return zero for `(foo)'. * Version 3.55. * make.texinfo (Rules: Multiple Targets): Make this node's `next' pointer point to `Static Pattern'. * make.texinfo (Makefiles: MAKEFILES Variable): Make this node's `prev' pointer point to `Makefile Names'. * make.1: Renamed to make.man. * compatMakefile: Define `mandir' and `manext'. (install): Depend on $(mandir)/make.$(manext). ($(mandir)/make.$(manext)): Depend on make.man and copy it to $@. ($(bindir)/make): Use `make' rather than $<; so Unix make can grok it. Thu Aug 24 03:35:48 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * variable.c (target_environment): Allow variables that start with underscores. Wed Aug 23 22:50:32 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * variable.c (target_environment): Reject variables that don't start with letters.

Sat Aug 19 06:03:16 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * remake.c (update_file_1): In the final loop, set the deps' `changed' members if they are newer than FILE. * remake.c (update_goal_chain): Under -d, print a message if we decide not to remake a makefile so as to avoid a possible infinite loop. Fri Aug 18 20:30:14 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * remake.c (remake_file): Cleaned up. * commands.c (execute_file_commands): If the commands are empty, set FILE->update_status to zero before returning. * remake.c (notice_finished_file): Set `last_mtime' fields to zero instead of calling name_mtime; file_mtime will do that later if anybody cares. Thu Aug 17 10:01:11 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * make.texinfo (Rules: Wildcards: Wildcard Examples): Give this node a `prev' pointer. * Version 3.54.9 (alpha). * make.texinfo: Fixed some @nodes. * remake.c (check_dep): Don't set *MUST_MAKE_PTR if FILE doesn't exist after running update_file. * remake.c (notice_finished_file): If FILE has no commands, pretend its modtime is now. * remake.c (update_file_1): In the loops that call update_file on the deps, compare modtimes before and after (unless deps are still being made) and set the deps' `changed' members. Do not set the `changed' members in the loop that prints the newer/older debugging messages. * remake.c (update_file_1): If no deps changed and FILE has no commands, decide it doesn't need remaking. * remake.c (update_file_1): Print a debugging message if we take commands from default_file. * make.texinfo (Rules: Directory Search: Selective Search): Removed note about warning for `vpath' with a constant pathname, since it isn't warned about anymore. * remake.c (update_goal_chain): If MAKEFILES, remove makefiles which are targets and have no deps. * make.texinfo (Makefiles: Remaking Makefiles): Document that makefiles will not be remade if they are targets but have no dependencies. Tue Aug 15 00:00:08 1989 Roland McGrath (roland at apple-gunkies.ai.mit.edu) * remake.c (notice_finished_file): Increment files_remade for non-phony files if they didn't exist before (even if they still don't). * job.c: Include and declare errno. * job.c (exec_command): If the execve fails with ENOEXEC (Exec format error), return instead of exiting the child process. * job.c (start_job): In the child side, if exec_command fails, try using the shell. * job.c (start_job): In the child side, call unblock_children instead of sigsetmask. * remake.c (notice_finished_file): Under -n or -q, always increment files_remade for non-phony files. * rule.c (intall_pattern_rule): Use find_percent. * vpath.c (vpath_search): Pass the `percent' members to pattern_matches. Mon Aug 14 23:30:24 1989 Roland McGrath (roland at apple-gunkies.ai.mit.edu) * vpath.c (struct vpath): New member `percent', to hold a pointer into the pattern where the % is. (construct_vpath_list): Call find_percent on the pattern and set the new `percent' member. * read.c (read_makefile): Don't run find_percent on `vpath' directive patterns. * function.c (pattern_matches): Take new arg PERCENT, a pointer into PATTERN where the % is. If PERCENT is nil, copy PATTERN into local space and run find_percent on it. (expand_function: `filter', `filter-out'): Pass new arg to pattern_matches. * read.c (record_files): Pass PATTERN_PERCENT to pattern_matches for static pattern rules. Save the percent pointer into implicit rule targets, and pass them to create_pattern_rule. * rule.c (convert_to_pattern): Pass new arg to create_pattern_rule. (create_pattern_rule): Take new arg TARGET_PERCENTS, nil or an array of pointers into the corresponding elements of TARGETS, where the %s are. Sun Aug 13 00:29:19 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * Version 3.54.8. * README.templatate, README-doc.template: New files, turned into README and README-doc to go into the two distribution tar files. * GNUmakefile: Added a rule to edit the version number in README.template and README-doc.template, producing README and README-doc. * remake.c (update_goal_chain): If -n or -q is in effect for a makefile, and it got updated, don't change STATUS, so we can still return -1 (meaning nothing was done). This avoids an infinite loop on "make -n Makefile".

(remake_file): Don't increment files_remade. * remake.c (update_file): Don't print "up to date" messages for phony files. * job.c (child_handler): Don't set C->file->update_status to 1 if start_job returns nonzero under -n or -t. * expand.c (variable_expand): Count parens in $(foo:a=b) refs. * main.c: Removed old declaration of `glob_tilde' (which hasn't existed for a few months). Tue Aug 8 23:53:43 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * job.c (exec_command): Fixed to not ignore the last path component and to do the right thing with an empty path. Fri Aug 4 15:58:19 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * remake.c (library_file_mtime): Look for libLIB.a, not /libLIB.a. Do VPATH search on libLIB.a, not /usr/lib/libLIB.a Thu Aug 3 20:42:00 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * job.c [HAVE_SYS_WAIT or not USG]: If WIFSIGNALED is not defined by , define it as (WTERMSIG != 0). Tue Aug 1 19:25:34 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * remake.c (remake_file): If FILE has no commands and is a target, don't set its time to now. The time gets reset by notice_finished_file anyway, and it isn't needed since check_dep checks for nonexistence. * Version 3.54.6. * 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 execute it.

Fri Jul 28 18:10:29 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * read.c (read_makefile): Match directives against collapsed line and use that for their args. * read.c (read_makefile): Warn about extra text after `include'. Tue Jul 25 14:34:25 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * make.texinfo (Rules: Directory Search: Selective Search): Fixed example to use correct `vpath' syntax. Mon Jul 24 12:10:58 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * Version 3.54.5. * job.c (start_job): In the child side, unblock SIGCHLD.

Tue Jul 11 06:45:24 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * GNUmakefile: Include COPYING in the doc tar file. * variable.c, read.c, misc.c, job.c, function.c: Replace some identical "for" loops with next_token or end_of_token calls. Mon Jul 10 16:55:08 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * Version 3.54.4. * compatMakefile: Documented new conditionals. * job.c: Don't define sys_siglist if HAVE_SIGLIST is defined. Don't define dup2 if HAVE_DUP2 is defined. * job.c (child_handler): Interpret the return from start_job correctly. * remake.c (update_file_1): Don't write "target not remade because of errors" message under -n or -q. * read.c: Declare getpwnam. * glob.c: Use if DIRENT is defined. [USG]: Don't declare memcpy, since does. Fri Jul 7 20:53:13 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * misc.c (collapse_line): Copy the line over in the right place. Fri Jul 7 18:33:24 1989 Roland McGrath (fsf at void.ai.mit.edu) * remake.c: Conditionalize inclusion of on not USG, since HP-UX defines a `struct file' there. Fri Jul 7 12:11:30 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * job.c: If WTERMSIG is defined by , define WAIT_T as int, and don't define other macros; this covers HP-UX. If WTERMSIG is not defined, use int or union wait based on USG and HAVE_SYS_WAIT; this covers BSD and SysV. * Version 3.54.3 (alpha). * job.c [USG and not USGr3]: Include and declare errno. * job.c (unblock_children [USG]): Declare child_handler. * job.c: Renamed WRETCODE to WEXITSTATUS. [HAVE_SYS_WAIT or not USG]: Undefine WTERMSIG, WCOREDUMP, and WEXITSTATUS before defining them. The HP-UX defines them. * main.c (main): If there are no goals, fatal AFTER printing the data base under -p. Thu Jul 6 22:43:33 1989 Roland McGrath (roland at apple-gunkies.ai.mit.edu) * glob.c [USG]: #define rindex as strrchr. * job.c [USG]: Include and #define getdtablesize() as NOFILE. Wed Jul 5 09:36:00 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * Version 3.54.2 (alpha). * expand.c (variable_expand): When expanding recursive variable references (${${a}}), use the correct delimiters in the constructed variable reference. Mon Jul 3 18:29:26 1989 Roland McGrath (roland at apple-gunkies.ai.mit.edu) * compatMakefile: Clear out and redefine the .SUFFIXES list because silly Sun 4 make defines .cps.h. * compatMakefile: Fix comment about -DNO_MINUS_C_MINUS_O. * remake.c: Include for O_* on 4.2. * commands.c: Define sigmask if it's not defined. Fri Jun 30 07:33:08 1989 Roland McGrath (roland at apple-gunkies.ai.mit.edu) * remake.c (remake_file): Don't always increment files_remade. * variable.c (push_new_variable_scope): Zero the new variable hash table. Thu Jun 29 17:14:32 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * expand.c (variable_expand): When terminating the variable expansion buffer, use variable_buffer_output instead of a simply zero store, because the buffer may need to be enlarged. Wed Jun 28 16:53:47 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * Version 3.54. * default.c (default_suffixes): Added `.ln'. (default_suffix_rules): Changed lint rules to use -C. Thu Jun 22 20:49:35 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * job.c (start_job): Set `environ' to CHILD->environment before execing in the child process! Tue Jun 20 17:23:13 1989 Roland McGrath (roland at spiff.ai.mit.edu) * compatMakefile: Put job.h and rule.h in `srcs'. * Version 3.53. Mon Jun 19 16:25:18 1989 Roland McGrath (roland at spiff.ai.mit.edu) * job.c (start_job): If there are no more commands, return nonzero under -n or -t. * compatMakefile (make): Pass `-f' to mv. * GNUmakefile: If `ARCH' or `machine' is defined, make $(ARCH)/*.o and $(ARCH)/make instead of *.o and make. * function.c (string_glob): Don't try to use freed storage! * read.c (readline): If there is only one byte of space in the buffer, enlarge the buffer before reading more. * arscan.c [M_XENIX]: Miscellaneous minor changes for Xenix. Sun Jun 18 13:07:45 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * GNUmakefile (depend): Split commands into two lines so they won't be so long when variable-expanded. * compatMakefile: Documented MINUS_C_MINUS_O meaning. The line describing it got removed when the USG/wait stuff was documented. Sat Jun 17 22:56:54 1989 Roland McGrath (roland at hobbes.ai.mit.edu) * Version 3.52. Mon Jun 12 17:45:11 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * remake.c (check_dep): Drop circular dependencies instead of fataling. (update_file_1 already does this.) * default.c (default_suffix_rules): For .s -> .o, put the -o flag to the assembler before the source file name. Sun Jun 11 12:00:52 1989 Roland McGrath (mcgrath at homer.Berkeley.EDU) * Version 3.51. * make.texinfo (Features): Noted 1003.2 requirement of `+' meaning. * file.c (remove_intermediates): If !SIG, write a single "rm" command line, listing all files. * read.c (read_makefile): Don't free the storage for the passed filename, since it might not be malloc'd. When doing an included makefile, free the name's storage. (read_all_makefiles): Use variable_expand to find the value of `MAKEFILES'. Free the storage for the names of -f makefiles. (read_makefile): Allocate storage for the makefile name in the `struct file' in read_makefiles. * make.texinfo (Running: Instead of Execution): Document the effect of + and $(MAKE)/${MAKE}. * make.texinfo (Functions: Foreach Function): Document that if the iteration variable was undefined before the `foreach' call, it will be undefined after the call. * commands.c: Split into commands.c, job.h, and job.c. * rule.c (try_implicit_rule, pattern_search): Moved to new file implicit.c. * rule.c: Split into rule.h, rule.c, and default.c. * default.c (install_default_pattern_rules): Renamed to install_default_implicit_rules. * make.h, main.c (main): Renamed uses. * make.c: Renamed to misc.c. * make.c (main, log_working_directory, decode_switches, decode_env_switches, define_makeflags, die, print_version, print_data_base): Moved to new file main.c. * commands.c (execute_file_commands): Don't collapse backslash-newlines here. When chopping the commands up into lines, don't chop at backslash-newlines. (start_job): Collapse backslash-newlines after printing the line. * commands.c (start_job): Don't collapse backslash-newlines here. (execute_file_commands): Collapse backslash-newlines before chopping the commands up into lines. * commands.c (set_file_variables): Initialize the length counters for $^ and $? to zero! * commands.c (start_job): Use vfork instead of fork. Someone else says the child and parent DO have separate file descriptors. * variable.c: Split internals into variable.c, function expansion into function.c, and variable expansion into expand.c. * function.c (handle_function): New function to check for a function invocation and expand it. * expand.c (variable_expand): Use handle_function. * variable.c (push_new_variable_scope): New function to push a new empty variable set onto the current setlist. (pop_variable_scope): New function to pop the topmost set from the current setlist and free its storage. * function.c (expand_function: `foreach'): Push a new variable scope for the iteration variable and pop the scope when finished. * variable.h: Declare new functions. * variable.c (initialize_variable_output): New function to return a pointer to the beginning of the output buffer. (save_variable_output): New function to save the variable output state. (restore_variable_output): New function to restore it. * expand.c (variable_expand): Use initialize_variable_output. (allocated_variable_expand): Use {save,restore}_variable_output. * variable.c (current_setlist): Renamed to current_variable_set_list and made global. Sat Jun 10 00:11:25 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * remake.c (library_file_mtime): Check for libNAME.a in the current directory before doing VPATH search. * variable.c (print_variable_set): Don't write "# Variables", and write fewer blank lines. (print_variable_data_base): Precede the variables with "# Variables". * make.c (main): Print the data base under -p after doing everything else, just before exitting. This way it gets info determined in updating the goal targets. * variable.c (print_variable_data_base): Split into print_variable, which prints one variable, and print_variable_set, which prints a set. Replaced with a call to print_variable_set for the global set. (print_file_variables): New function to print a given file's local variables. * file.c (print_file_data_base): Call print_file_variables to print each file's local variables. * commands.c (set_file_variables): Actually define the values for the $^ and $? variables!!! * make.texinfo (Implicit: Pattern Rules: Automatic): Document new D and F versions of $^ and $?. * commands.c (start_job): In the child fork, use getdtablesize and a 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 command-line variable definitions. 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. * make.c (main): Don't set glob_tilde (it no longer exists). * 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. Wed May 24 00:20:04 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * 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. (record_files): Take another arg, PATTERN_PERCENT, a pointer to the % in PATTERN. (read_makefile): Pass PATTERN_PERCENT to record_files. * make.texinfo (Rules: Static Pattern: Static Usage, Rules: Directory Search: Selective Search, Functions: Text Functions): Documented that `%' can be quoted. * variable.c (expand_function: `filter'/`filter-out'): Use pattern_p to allow quoted %s in patterns. * variable.c (patsubst_expand): Use pattern_p on PATTERN and REPLACE to allow quoted %s. Quoting backslashes are removed from REPLACE even if PATTERN contains no unquoted %. * 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 names taken from the list, instead of allocating and freeing one every time. Fri May 19 18:06:26 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * make.c (decode_switches): Get floating numbers from the right string. Sun May 14 13:48:04 1989 Roland McGrath (mcgrath at homer.Berkeley.EDU) * commands.c (delete_child_targets): When deleting `also_make' files, include the target's name in the message: make: *** [foo] Deleting file `bar' Sat May 13 17:34:26 1989 Roland McGrath (mcgrath at tully.Berkeley.EDU) * make.c (max_load_average, default_load_average): Default to -1. * load.c (wait_to_start_job): Return if max_load_average is < 0.0, not equal.

Mon Apr 10 19:31:34 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * rule.c (pattern_search): Put rules with `subdir' flags set in TRYRULES, since these might be valid with VPATHs. In the TRYRULES loop, don't do lookup_file or file_exists_p calls for dependencies of rules with `subdir' flags set, but still do vpath_search calls and intermediate-file searches. Thu Apr 6 16:33:00 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * make.texinfo (Implicit: Pattern Rules: Automatic): Document the new definition of $* for explicit rules. * commands.c (execute_file_commands): If FILE->stem is nil, figure out if FILE->name ends in a suffix in the .SUFFIXES list; if so, store the name sans suffix in FILE->stem (and $*). Wed Apr 5 15:24:48 1989 Roland McGrath (mcgrath at helen.Berkeley.EDU) * file.c (remove_intermediates): Don't use `file_exists_p' to check for the existence of intermediate files, because the hashed directories will probably be out of date. * commands.c (child_handler): Free the good stdin before running the next command line. * commands.c [USG] (init_siglist): Don't case SIGEMT if it's not defined.

If not just remove the old one for put in the new one. * remake.c (update_file_1, check_dep): Changed it back so that equal modtimes to NOT make dependencies be considered newer. RCS checks out files with equal modtimes as the RCS files, so this screws it. * make.h, glob.c: If __GNUC__ is defined, use __builtin_alloca. * Makefile: Use variables `ALLOCA' and `ALLOCASRC' so systems without a good standard alloca can get it from the Emacs distribution (or somewhere). * dir.c: Don't include , since make.h does. * make.c: Removed debugging version of getwd. Thu Mar 23 16:16:27 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * Version 3.43. * remake.c (update_file_1): If a dependency loop is found, don't fatal.

However, there is no way to make setting these affect the implicit rules, unless we trash FC and FFLAGS (which BSD uses). [USG]: Set GET to `get' rather than `/usr/sccs/get'. Sun Mar 19 20:00:27 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU) * vpath.c (construct_vpath_list): Don't replace VPATH[ELEM] with dir_name (V), because the latter may get freed.

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. * ar.c, arscan.c: Don't assume `long int' and `int' are the same. * commands.c [USG]: Fixed wait status bit encoding.

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.

(command_switches): Added `-l' switch to set `max_load_average'. * load.c (load_average): New file and function to return a double that is the current load average (1.00 scale). * GNUmakefile, oldMakefile: Pass flags in $(LOAD_AVG) for load.c. Thu Dec 15 15:22:08 1988 Roland McGrath (mcgrath at homer.Berkeley.EDU) * Makefile: Renamed to oldMakefile. * 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 nonzero is successfully remade. * commands.c: Don't include . * commands.c (construct_command_argv): Added ` to sh_chars. * make.h: Don't declare construct_makeflags. * make.c (main): Set up MAKEFLAGS and MFLAGS and make an environment both before and after reading the makefiles, so the makefiles can use them and possible change them, and later children will get the right information. (construct_makeflags): Replaced with define_makeflags (static void), which defines the two variables. * variable.c (define_automatic_variables): Don't define MAKEFLAGS and MFLAGS. Mon Dec 12 14:40:31 1988 Roland McGrath (mcgrath at helen.Berkeley.EDU) * 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 instead of . What we need is really in , and while BSD includes , USG doesn't. * make.c (main): Figure out the program name before doing anything which might need it (in a call to error or fatal). * dir.c, glob.c: Use `struct dirent' and for USGr3. * arscan.c (ar_scan): Added missing & before buf (which is an int) if SARMAG is not defined (SysV). Fri Dec 9 18:44:13 1988 Roland McGrath (mcgrath at pepper.Berkeley.EDU) * Version 3.26. * dir.c (find_directory, dir_file_exists_p): Keep track of how many 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. * GNUmakefile: Don't include GNUmakefile or depend in the distribution file.

Sat Nov 26 11:36:31 1988 Roland McGrath (mcgrath at homer.Berkeley.EDU) * variable.c (expand_function: `filter', `filter-out'): Fixed so that filter-out works right. * variable.c (expand_function: `filter', `filter-out'): Made these 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 at least one error message that need that many. Too bad vfprintf is not universal! * Version 3.23. * 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 COMMANDS_STARTED and construct a `struct commands. Thu Nov 24 14:36:33 1988 Roland McGrath (mcgrath at paris.Berkeley.EDU) * Version 3.22. * 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 else, so we know it even if we don't need it for the value of `MAKE', since we might want it when re-execing. Wed Nov 23 13:34:44 1988 Roland McGrath (mcgrath at homer.Berkeley.EDU) * Version 3.21. * read.c (record_files): Eliminate duplicate deps in a chain. * variable.c (expand_function: `sort'): Pass the right number to qsort, not one less. * remake.c (remake_file): Always call notice_finished_file if FILE->command_state == cs_finished. * commands.c (execute_file_commands): Call notice_finished_file to set FILE's status correctly when start_job fails (because it's out of commands or running under -n). Fri Nov 18 15:31:12 1988 Roland McGrath (mcgrath at saffron.Berkeley.EDU) * Version 3.20. * remake.c (update_file_1): Set the `update_status' of FILE to nonzero and set FILE's `updated' bit if we have decided to give up on remaking FILE because of errors in the dependencies. * rule.c (pattern_search): Debugging messages use `dependency' (vs. `dependent') properly. * make.texinfo (Conditionals: Conditional Syntax): Function index entries for `ifndef' and `ifneq'. * variable.c (define_automatic_variables): Define `MAKELEVEL' to the decimal number of the makelevel, since it may be malformed or blank. * remake.c (remake_file): Call notice_finished_file after touching. Sat Nov 12 19:29:34 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * Version 3.19. * GNUmakefile (dist): Pass the `-f' flag to compress. * vpath.c (build_vpath_lists): Check for VPATHS being nil after constructing the general VPATH list from the `VPATH' variable.

Thu Nov 10 16:51:36 1988 Roland McGrath (mcgrath at basil.Berkeley.EDU) * Version 3.18. * read.c (read_makefile): Made it eat leading spaces and formfeeds (but not tabs), like it's documented to. * read.c (read_makefile): Let included makefiles determine the default goal, as is done by System V Make. Tue Nov 1 19:03:08 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * variable.c (new_environ): Don't increment VCNT when a variable is rejected. Fri Oct 28 16:54:15 1988 Roland McGrath (mcgrath at basil.Berkeley.EDU) * Version 3.17. * rule.c (convert_to_pattern): Don't use the same storage for a name in two rules since new_pattern_rule may free this storage when a rule is discarded. * rule.c (new_pattern_rule): Undid useless change I made Oct 25. Thu Oct 27 19:17:53 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * Version 3.16. * GNUmakefile, Makefile: Fixed a typo in a comment. * Makefile: Removed malloc.o from object file list. * variable.c: Removed old debugging #define's for xmalloc and xrealloc so non-ANSI cpp's won't barf. * make.c (main): Made local array for temp file name static so compilers that don't do auto aggregate initialization won't barf. * read.c: Removed static declaration of copy_dep_chain since it is no longer static. Tue Oct 25 16:59:30 1988 Roland McGrath (mcgrath at pepper.Berkeley.EDU) * rule.c (new_pattern_rule): If we threw out the new rule because it matched an old one and OVERRIDE was zero, don't put the freed pointer in the chain! Wed Oct 19 15:07:43 1988 Roland McGrath (mcgrath at pepper.Berkeley.EDU) * Version 3.15. * variable.c (expand_function: `sort'): Don't do the sorting and writing out if there were no words in the first place. * remake.c (remake_file): Only fail with a "no way to make" message for a dependency (non-target) file. If we don't know how to remake a target file, pretend it was successfully remade and is very new. * remake.c (remake_file): Don't increment `files_remade' for a non-target file we don't know how to remake. * read.c (record_files): Don't die with "both : and :: entries" for a file whose `is_target' flag is not set. Tue Oct 18 17:24:11 1988 Roland McGrath (mcgrath at paris.Berkeley.EDU) * variable.c (expand_function: `patsubst', `subst'): Free the right things! * variable.c (expand_function: `subst'): Don't clobber the pointer to the end of the second arg and then try to use it!!!

Fri Oct 14 18:35:00 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * read.c (read_all_makefiles): Pass second arg to read_makefile for default makefiles. Thu Oct 13 16:40:08 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * Version 3.13. * GNUmakefile: Added an explicit rule for make.dvi since the built-in .texinfo.dvi implicit rule is screwed up. * rule.c (default_suffix_rules): Added a comment that the .texinfo.dvi rule does not work because of an ahem, feature of Make that at some point will be fixed--er, enhanced to alleviate this difficulty. * rule.c (default_suffix_rules): Fixed Texinfo -> DVI rule (again). * make.texinfo (Commands: Execution): Documented new competing for standard input among children. * commands.c (struct child): Added `good_stdin' flag to tell if this child has the stdin that doesn't point into nirvana. (good_stdin_used): New variable to tell if any child has the good standard input. (child_handler): Reset `good_stdin_used' if a dead child's `good_stdin' flag is set. (start_job): Give the new child the good standard input if `good_stdin_used' is no set, and set the child's `good_stdin' flag appropriately. * rule.c (default_suffix_rules): Changed Texinfo -> DVI rule to work better (I hope). * read.c (read_all_makefiles): Stop reading default makefiles after one is found. * read.c (read_makefile): Reset `reading_filename' and `reading_lineno_ptr' after recursing for an included makefile. * GNUmakefile: New GNU Make-specific makefile that does everything Makefile does plus distribution stuff, and doesn't contain any hacks to try to work with Unix make. * Makefile: Removed distribution stuff. * make.c (main): Use mktemp to construct the names of temporary files used for standard input makefiles. * make.c (main): Don't turn standard input into a broken pipe. * commands.c (start_job): Keep two extra file descriptors around: a good standard input, and a bad one that reads from a broken pipe. On the child side of the fork, if there are other children, give 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 and such things to be done when commands finish. (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 were no parallelism. Wed Oct 12 15:59:03 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * remake.c (remake_file): Don't print a "No way to make" message for targets whose `dontcare' flags are set. * read.c (read_all_makefiles): Set the `dontcare' flag of the `struct file' each default makefile added to the chain. * 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 they will be updated if possible, giving their `struct dep's' `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, go through the list of default names, trying to make one, stopping if one is made. * remake.c (remake_file): Set STATUS to 0 after successfully touching. * dir.c (file_impossible, file_impossible_p): Don't clobber FILENAME to "" and then try to to a strcmp on it!!! Mon Oct 10 16:09:18 1988 Roland McGrath (mcgrath at cinnamon.Berkeley.EDU) * make.c (main): Don't do `dir_load (".")'. * rule.c (count_implicit_rule_limits), vpath.c (construct_vpath_list): Test the existence of a given directory by `dir_file_exists_p (DIR, ".")' and assume that if this returns zero, it means the directory really does not exist. * dir.c (struct dirdata): Replaced with `struct directory' for directories, each containing a chain of `struct dirfiles', one for each file (real or impossible). (dir_load): Removed. (find_directory): New function to find the `struct directory' for a named directory and return it (possibly creating a new one). (dir_file_exists_p): Read the directory on the fly if its stream is still valid (and ever was) if the file we're looking for is not already in the hash tables. (file_impossible, file_impossible_p, dir_name, print_dir_data_base): Use the new directory/file scheme. * make.texinfo: Miscellaneous editorial changes and clarifiactions. * commands.c (struct child): Remove `environ' member.

Thu Oct 6 17:52:35 1988 Roland McGrath (mcgrath at paris.Berkeley.EDU) * Version 3.11. * make.texinfo: Fixed a line that got garbaged somehow. Mon Oct 3 16:14:39 1988 Roland McGrath (mcgrath at paris.Berkeley.EDU) * make.c (main): Try to move back to the directory we started in before re-exec ourself. * remake.c (update_file_1): A double-colon target with no deps always needs to be remade. * remake.c (remake_file): Changed "No way to make" message to say `target' rather than `file'.

Updated the `Features' section a bit. * make.c (main): Read switches from MAKEFLAGS and MFLAGS variables after reading in makefiles. * make.c (main): Put a line "/tmp/foo:;" rather than ".PHONY: /tmp/foo" in front of temp files made for stdin makefiles. * remake.c (update_file): Test the state of the right `struct file' for double-colon files. * make.c (main): Put a ".PHONY: /tmp/foo" line in front of temp files made for stdin makefiles so they won't be remade when we re-exec. Kludge-o-matic!! * remake.c (update_goal_chain): Judge files as being finished based on their `updated' flag, not their state. * read.c (read_makefile): Don't check for FILENAME being "-". (read_all_makefiles): Set each element of MAKEFILES to the name put in READ_MAKEFILES by read_makefile, since read_makefile may free the storage for the name it is passed, and someone might want to look at the elements of MAKEFILES again. * 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. * make.c (construct_makeflags): Always put out `-j1'. Sat Oct 1 00:19:59 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * commands.c (execute_file_commands): If commands are nothing but whitespace, set the state to `cs_finished' before returning 0. * make.c (decode_switches): Allocate space for args in stringlists so they can be freed later. * make.h: Declare `makelevel'. * variable.c (makelevel): Moved to make.c (and made global). * make.c (fatal, error): Print the makelevel if it's > 0. (perror_with_name): Use error rather than calling fprintf directly. (pfatal_with_name): Use fatal rather than fprintf and die. * variable.c (new_environ): Don't put default variables (origin `o_default') into the environment; they just take up space. * read.c (read_makefile): Don't add FILENAME to the chain of read makefiles if it's "-" (standard input). * remake.c (update_goal_chain): Set STATUS correctly when nothing happens (as well as in all other situations). * make.c (construct_makeflags): Put a `-' before each switch and spaces between them. * Version 3.10. * commands.c (wait_for_children): Don't check if `children' is nil. This is the case when waiting for the child of a `shell' function. * dir.c (dir_load): Don't add a hash-table entry for directory DIRNAME and filename "" if DIRNAME doesn't exist. * commands.c (execute_file_commands): Return 0 after start_job returns 1 (failure) under the -n flag. * remake.c (remake_file): Set the state to `cs_finished' when not calling execute_file_commands. * remake.c (update_goal_chain): Second arg is now MAKEFILES, nonzero meaning to disable -t, -q, and -n for each target unless the target was also given on the command-line. * read.c (read_makefile): Enter the `struct file's for the makefiles added to the `read_makefiles' `struct dep' chain. * remake.c (update_goal_chain): Made it not enter the files for the goals in the chain. It will already have been done. * rule.c (convert_to_pattern): Null-terminate the names of targets and deps of the pattern rules properly. Fri Sep 30 18:56:20 1988 Roland McGrath (mcgrath at nutmeg.Berkeley.EDU) * make.c (main): Call install_default_pattern_rules. * make.h: Declare copy_dep_chain. * read.c (copy_dep_chain): Moved to make.c (and made global). * make.c (main): Call update_goal_chain to update goals.

(update_goal_chain): New function to update a `struct dep' chain of goals, waiting until they are all finished before returning. * make.h: Don't declare update_file. Declare update_goal_chain. * make.c (main): Call snap_deps, etc. that were in read_all_makefiles. * read.c (find_makefile): Removed this function. (read_all_makefiles): Don't update makefiles, don't diddle with pattern rules, don't call snap_deps, etc. Return a `struct dep' chain of all makefiles read. (read_makefile): Now takes two args: FILENAME and TYPE, which is 0 for a normal makefile, 1 for MAKEFILES variable or 2 for an included makefile. Add a `struct dep' containing the name of the makefile (as it was found in the search path for type 2s), and TYPE in the `changed' member to the global `read_makefiles' chain. * make.h, rule.c (displace_pattern_rules, add_displaced_pattern_rules): Removed these functions. * read.c (read_makefile): Variable-expand the name of an `include'd makefile before calling find_makefile on it. * file.c (snap_deps): If the `struct file' for a `struct dep' already exists, free the `struct dep's `name' member before setting it to nil (since this info is in the `struct file'). * read.c (copy_dep_chain): Made it copy each name rather than leaving multiple `struct dep's with the same pointers. Thu Sep 29 19:08:13 1988 Roland McGrath (mcgrath at catnip.Berkeley.EDU) * make.c (decode_switches): Fixed second decode_env_switches call to use correct length of "MFLAGS" (6, not 5). * read.c (read_makefile): Don't stop reading when readline returns zero lines read. Only stop when the stream reaches EOF. This makes it recognize the last line of a makefile without a newline. * remake.c (remake_file): If we don't know how to make FILE, set its command state to `cs_finished'. * remake.c (update_file): Don't write the "up to date" message if update_file_1 returned a nonzero status. Wed Sep 28 16:30:07 1988 Roland McGrath (mcgrath at catnip.Berkeley.EDU) * commands.c (child_handler): Set the `update_status' member properly for ignored errors. * rule.c (convert_to_pattern): Made it not care about if the target suffix comes before the source suffix in the .SUFFIXES list. * make.texinfo: Misc editorial changes. * commands.c (wait_for_children): Return immediately if `children' is nil (there are no children). Tue Sep 27 15:33:14 1988 Roland McGrath (mcgrath at pepper.Berkeley.EDU) * Version 3.09. * commands.c (struct child): New member `command_ptr' to hold the current position in the commands. The `commands' member is never changed. (start_job, child_handler, execute_file_commands): Use new method for `commands' and `command_ptr' members. * make.c (decode_env_switches): Skip past an invalid letter (instead of looping forever). * commands.c (struct child): Add `environ' member to hold the environment for this child. (execute_file_commands): Get a new environment from new_environ and put in the the new `struct child's `environ' member. (child_handler): When freeing a child, free its `commands' member, the elements of its `environ' array and its `environ' member itself. (start_job): Set `environ' to the child's `environ' member before exec'ing the command. * variable.h, variable.c (new_environ): Made it return the new environment, not putting it in `environ'. * remake.c (update_file): Don't give a "is up to date" message unless no files were remade and the state went from `cs_not_started' to `cs_finished', so repeat calls to finish jobs won't get the message. Mon Sep 26 16:26:08 1988 Roland McGrath (mcgrath at helen.Berkeley.EDU) * Version 3.08. * make.texinfo (Commands: Execution): Documented that children will be waited for rather than killed. * commands.c (fatal_error_signal): Wait for children.

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. (kill_children): Call child_handler with zero rather than SIGCHLD. * 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. Wed Sep 21 15:57:41 1988 Roland McGrath (mcgrath at helen.Berkeley.EDU) * read.c (read_all_makefiles): Call convert_to_pattern before recomputing the limits after adding the displaced rules. * make.c (main): Move calls to snap_deps, convert_to_pattern, and build_vpath_lists to read_all_makefiles. * read.c (read_all_makefiles): Install the default pattern rules before checking to remake the makefiles, displace these rules before reading in the makefiles, and then add the displaced rules to the chain after reading in all the makefiles. * make.c (main): Don't call install_default_pattern_rules or count_implicit_rule_limits. * 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 the current chain. * make.texinfo (Implicit: Search Algorithm): Fixed PREV reference. * make.c (main): Call construct_include_path right after decoding the switches. * read.c (find_makefile): Use rename_file. * file.h: Declare rename_file. * file.c (rename_file): New function to rename a `struct file' and put it in the correct hash bucket. * read.c (find_makefile): New function to find and update a makefile. (read_all_makefilese): Use find_makefile. (read_makefile): Don't do updating. Removed UPDATEIT arg. * remake.c (update_file_1): Took out setting the `updated' member to -1 rather than 1 sometimes. * make.c (main): Made it print version info before doing anything else. * remake.c (library_file_mtime, f_mtime): Removed use of last two arguments to vpath_search. * rule.c (pattern_search): Removed use of last two arguments 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. * remake.c (update_file): Print a "File `foo' up to date'" message under -p. * commands.c (execute_file_commands): Allocate one byte for each of $^ and $< rather than zero if they are to be empty. Fri Sep 16 13:59:59 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * Version 3.06. * make.c (command_switches): Fixed entry for `-o' switch. * make.texinfo: Renamed -c switch to -C. * make.c: Renamed -c switch to -C. * Miscellaneous de-linting. * read.c (record_files): Made it not free the storage for the name if it started with `./' and was therefore not quite the same as in 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. * variable.c: Increased number of hash buckets to 257. * file.c: Increased number of hash buckets to 1007. * rule.c (count_implicit_rule_limits): Moved comptation of `maxsuffix' to convert_to_pattern, since that function uses `maxsuffix', and must be called before count_implicit_rule_limits. * rule.c (pattern_search): If an existent (non-intermediate) dependency was found via a terminal rule, set its `tried_implicit' flag, so it will never have implicit rule search done. * glob.c: Bug fix to avoid alloca(0). * arscan.c: USG and Sun386i fixes. Thu Sep 15 19:40:26 1988 Roland McGrath (mcgrath at helen.Berkeley.EDU) * make.texinfo: Fixed some typos and spelling errors. Wed Sep 7 14:20:39 1988 Roland McGrath (mcgrath at helen.Berkeley.EDU) * make.c (decode_switches): Fixed bug wherein a bad option would give a useless error message and loop forever. Tue Sep 6 14:36:02 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * make.texinfo: Documented `shell' function. * variable.c (expand_function): New function `shell', does backquote-style command expansion of its arg. * commands.c (execute_command_line): Second arg OUTBUF, if not nil, 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. Added a comment about defining `NO_MINUS_C_MINUS_O' if necessary. * Version 3.05. * rule.c (default_suffix_rules): Don't pass `-o' switches with `-c' switches if `NO_MINUS_C_MINUS_O' is #define'd. * make.texinfo: Documented `GNUmakefile'. * read.c (read_all_makefiles): Made it try default makefile `GNUmakefile' before others. * make.texinfo: Added new-style Texinfo header thingies. Sat Sep 3 18:09:39 1988 Roland McGrath (mcgrath at homer.Berkeley.EDU) * Version 3.04. * make.texinfo (Chained Rules): Added a @cindex about using .PRECIOUS to preserve intermediate files. * remake.c (update_file_1): Made it not just return before executing commands under -p. * rule.c (default_pattern_rules, default_variables): Made it use `$(AR)' for `ar r' (to put files in archives). * vpath.c (build_vpath_lists): Made it recursively expand the `VPATH' variable (by using variable_expand instead of lookup_variable). * read.c (conditional_line): Made it not swallow whitespace after the comma in an `ifeq' using the `(a,b)' syntax. * rule.c (count_implicit_rule_limits): Made it not crash if a pattern rule dep begins with `/'. 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 variable *name*, not a reference. * make.texinfo: Clarified that both -Idir and -I dir are allowed. Sat Aug 27 13:49:28 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * remake.c (remake_file): Made touching phonies work right. Wed Aug 24 20:40:48 1988 Roland McGrath (mcgrath at nutmeg.Berkeley.EDU) * make.texinfo: Removed reference to `RANLIB' variable. * Version 3.03. * variables.c (expand_function): Added `origin' function. * make.texinfo: Documented same. * read.c (record_files): Made double-colon entries work. Sat Aug 20 21:09:39 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * make.c (collapse_continuations): Bug fix from RMS. * rule.c (install_default_pattern_rules): Made it set the `in_use' flag of the created rules to zero, rather than letting it be random garbage. * rule.c (pattern_search): Fixed putting `also make' targets into file strucutres. * read.c (record_files): Fixed bug which made double-colon entries make it read off into space. * make.c (decode_switches): Made it understand `ignored' switches rather than dumping core. Sun Aug 14 16:49:00 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * read.c (read_makefile): Made `include' filenames be variable-expanded. * read.c (read_makefile): Fixed an error message. * read.c (read_makefile): Made it accept ^L's as whitespace. * make.c (next_token, end_of_token): Ditto. * vpath.c (vpath_search): Fixed it so that the general VPATH (from the variable) is always checked, even if a selective VPATH (from a directive) matched the filename. Sat Aug 13 14:20:46 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * make.c (decode_switches, main): Made the command switches be processed from a table of switches, variables, and types. No functions are passed argc and argv any more. They are passed arrays of strings they need to process. * read.c (read_all_makefiles): Made it take an array rather than argc and argv. (construct_include_path): Ditto. * make.c (collapse_continuations): Made it work right (I hope). * make.texinfo: Minor editorial changes. * read.c (read_makefile): Minor speed improvement by freeing and then mallocing something rather than reallocing it to avoid the unnecessary bcopy. Thu Aug 11 00:10:43 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * make.texinfo: Fixed some unquoted @'s. * make.texinfo: Documented multiple-target pattern rules. Miscellaneous minor editorial changes and corrections. * make.texinfo (Implicit: Catalogue of Rules): Removed the list of variables. That's what the next section is for. (Implicit: Implicit Variables): Made it agree with reality. 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 '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 the given file's commands in its `also_make' member. * remake.c (update_file_1): Made it mark the files in a file's `also_make' member as updated when the file is updated. * variable.c (try_variable_definition): Fixed a bug which made it define a variable with the name of the whole definition when there 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. Tue Aug 9 10:04:50 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * variable.h: Added `o_default' to `enum variable_origin'. * variable.c (print_variable_data_base): Made it print the origins of the variables. * rule.c (install_default_pattern_rules): Made it define the default variables with origin `o_default'. * make.texinfo: Documented -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 the files used in the comparison to determine whether or not a second TeX run is necessary. * make.texinfo: Fixed some overfull TeX hboxes. * make.texinfo (Implicit: Catalogue of Rules): Fixed a Texinfo error. * rule.c (create_pattern_rule): Fixed bug wherein index was not being passed its second arg. * read.c (getline): Merged back into readline. * rule.c (default_suffixes, default_suffix_rules, default_variables): Added .texinfo.info rule. * make.texinfo (Implicit: Catalogue of Rules): Documented .texinfo.dvi and .texinfo.info rules. * make.texinfo (Top): Changed `last updated' date to be correct (for the last time it was updated, not today). Changed `for version 3.00' since it's not going to be called that. Sat Aug 6 19:51:10 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU) * commands.c (print_commands): Added this function to print the contents of a `struct commands' for -p. * rule.c (print_rule_data_base): Use above. * file.c (print_file_data_base): Ditto. * rule.c (count_implicit_rule_limits, new_pattern_rule, install_pattern_rule, print_rule_data_base): Made it understand the changed `struct rule' and act accordingly. (freerule): Added this function to free all the storage used by a rule. * rule.c (pattern_search): Made it grok multiple targets of pattern rules. The matching is done properly, but at present, only the 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 rules whose target suffix comes before the dependency suffix in the .SUFFIXES list. * variable.c (define_automatic_variables): Made all automatic 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. * read.c (record_files): Made it set the stem for $* for all static 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 remake.c and used only there. (main): Cleaned up somewhat. (decode_switches): Cleaned up a bit. Made an unknown option be a 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 slightly. (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.
