Version 3.81 released.
* NEWS: Updated for 3.81.
* README.cvs: Mention that vpath builds are not supported out of
CVS. Fixes Savannah bug #16236.
Remove update of make.texi from the list of things to do; we use
version.texi now.
2006-03-26 Paul D. Smith <psmith@gnu.org>
* doc/make.texi: Clean up licensing. Use @copying and version.texi
support from automake, as described in the Texinfo manual.
2006-03-25 Eli Zaretskii <eliz@gnu.org>
* implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
with lastslash, since the latter points to filename, not to
target.
* job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
Declare and define sh_chars_sh[].
2006-03-23 Paul D. Smith <psmith@gnu.org>
* configure.in: Look for build.sh.in in $srcdir so it will be
built for remote configurations as well.
* Makefile.am: Make sure to clean up build.sh during distclean.
Fixes Savannah bug #16166.
* misc.c (log_access): Takes a const char *.
* function.c (fold_newlines): Takes an unsigned int *.
Both fixes for Savannah bug #16170.
2006-03-22 Boris Kolpackov <boris@kolpackov.net>
* implicit.c (pattern_search): Call set_file_variables only
if we have prerequisites that need second expansion. Fixes
Savannah bug #16140.
2006-03-19 Paul D. Smith <psmith@gnu.org>
* remake.c (update_file): Add alloca(0) to clean up alloca'd
memory on hosts that don't support it directly.
* README.cvs: Add information on steps for making a release (to
make sure I don't forget any).
* main.c (clean_jobserver): Move jobserver cleanup code into a new
function.
(die): Cleanup code was removed from here; call the new function.
(main): If we are re-execing, clean up the jobserver first so we
don't leak file descriptors.
Fix bug reported by Craig Fithian <craig.fithian@citigroup.com>.
2006-03-17 Paul D. Smith <psmith@gnu.org>
* maintMakefile (do-po-update): Rewrite this rule to clean up and
allow multiple concurrent runs.
Patch from Joseph Myers <joseph@codesourcery.com>
2006-03-17 Boris Kolpackov <boris@kolpackov.net>
* dep.h (struct dep): Add the stem field.
* misc.c (alloc_dep, free_dep): New functions.
(copy_dep_chain): Copy stem.
(free_dep_chain): Use free_dep.
* read.c (record_files): Store stem in the dependency line.
* file.c (expand_deps): Use stem stored in the dependency line. Use
free_dep_chain instead of free_ns_chain.
* implicit.c (pattern_search): Use alloc_dep and free_dep.
* read.c (read_all_makefiles, eval_makefile, eval): Ditto.
* main.c (main, handle_non_switch_argument): Ditto.
* remake.c (check_dep): Ditto.
* rule.c (convert_suffix_rule, freerule): Ditto.
2006-03-14 Paul D. Smith <psmith@gnu.org>
* expand.c (variable_append): Instead of appending everything then
expanding the result, we expand (or not, if it's simple) each part
as we add it.
(allocated_variable_append): Don't expand the final result.
Fixes Savannah bug #15913.
2006-03-09 Paul Smith <psmith@gnu.org>
* remake.c (update_file_1): Revert the change of 3 Jan 2006 which
listed non-existent files as changed. Turns out there's a bug in
the Linux kernel builds which means that this change causes
everything to rebuild every time. We will re-introduce this fix
in the next release, to give them time to fix their build system.
Fixes Savannah bug #16002.
Introduces Savannah bug #16051.
* implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
we *don't* find UNIX "/".
Reported by David Ergo <david.ergo@alterface.com>
2006-03-04 Eli Zaretskii <eliz@gnu.org>
* variable.c (do_variable_definition) [WINDOWS32]: Call the shell
locator function find_and_set_default_shell if SHELL came from the
command line.
2006-02-20 Paul D. Smith <psmith@gnu.org>
* variable.c (merge_variable_set_lists): It's legal for *setlist0
to be null; don't core in that case.
2006-02-19 Paul D. Smith <psmith@gnu.org>
* commands.c (set_file_variables): Realloc, not malloc, the static
string values to avoid memory leaks.
* expand.c (recursively_expand_for_file): Only set reading_file to
an initialized value.
* implicit.c (pattern_search): We need to make a copy of the stem
if we get it from an intermediate dep, since those get freed.
* file.c (lookup_file) [VMS]: Don't lowercase special targets that
begin with ".".
(enter_file) [VMS]: Ditto.
Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.
2006-02-24 Eli Zaretskii <eliz@gnu.org>
* job.c (construct_command_argv_internal): Fix last change.
* w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
dwStdout, and dwStderr unsigned int: avoids compiler warnings in
the calls to _beginthreadex.
* expand.c (recursively_expand_for_file): Initialize `save' to
prevent compiler warnings.
2006-02-18 Eli Zaretskii <eliz@gnu.org>
* job.c (construct_command_argv_internal): Don't create a temporary
script/batch file if we are under -n. Call _setmode to switch the
script file stream to text mode.
2006-02-17 Paul D. Smith <psmith@gnu.org>
* variable.c (merge_variable_set_lists): Don't try to merge the
global_setlist. Not only is this useless, but it can lead to
circularities in the linked list, if global_setlist->next in one
list gets set to point to another list which also ends in
global_setlist.
Fixes Savannah bug #15757.
2006-02-15 Paul D. Smith <psmith@gnu.org>
Fix for Savannah bug #106.
* expand.c (expanding_var): Keep track of which variable we're
expanding. If no variable is being expanded, it's the same as
reading_file.
* make.h (expanding_var): Declare it.
* expand.c (recursively_expand_for_file): Set expanding_var to the
current variable we're expanding, unless there's no file info in
it (could happen if it comes from the command line or a default
variable). Restore it before we exit.
* expand.c (variable_expand_string): Use the expanding_var file
info instead of the reading_file info.
* function.c (check_numeric): Ditto.
(func_word): Ditto.
(func_wordlist): Ditto.
(func_error): Ditto.
(expand_builtin_function): Ditto.
(handle_function): Ditto.
2006-02-14 Paul D. Smith <psmith@gnu.org>
* read.c (eval): Even if the included filenames expands to the
empty string we still need to free the allocated buffer.
* implicit.c (pattern_search): If we allocated a variable set for
an impossible file, free it.
* variable.c (free_variable_set): New function.
* variable.h: Declare it.
* read.c (read_all_makefiles): Makefile names are kept in the
strcache, so there's never any need to alloc/free them.
(eval): Ditto.
* main.c (main): Add "archives" to the .FEATURES variable if
archive support is enabled.
* doc/make.texi (Special Variables): Document it.
2006-02-13 Paul D. Smith <psmith@gnu.org>
* implicit.c (pattern_search): Add checking for DOS pathnames to
the pattern rule target LASTSLASH manipulation.
Fixes Savannah bug #11183.
2006-02-11 Paul D. Smith <psmith@gnu.org>
* (ALL FILES): Updated copyright and license notices.
2006-02-10 Paul D. Smith <psmith@gnu.org>
A new internal capability: the string cache is a read-only cache
of strings, with a hash table interface for fast lookup. Nothing
in the cache will ever be freed, so there's no need for reference
counting, etc. This is the beginning of a full solution for
Savannah bug #15182, but for now we only store makefile names here.
* strcache.c: New file. Implement a read-only string cache.
* make.h: Add prototypes for new functions.
* main.c (initialize_global_hash_tables): Initialize the string cache.
(print_data_base): Print string cache stats.
* read.c (eval_makefile): Use the string cache to store makefile
names. Rewrite the string allocation to be sure we free everything.
2006-02-10 Eli Zaretskii <eliz@gnu.org>
* dir.c (dir_contents_file_exists_p): Don't opendir if the
directory time stamp didn't change, except on FAT filesystems.
Suggested by J. David Bryan <jdbryan@acm.org>.
2006-02-09 Paul D. Smith <psmith@gnu.org>
* function.c (func_or): Implement a short-circuiting OR function.
(func_and): Implement a short-circuiting AND function.
(function_table_init): Update the table with the new functions.
* doc/make.texi (Conditional Functions): Changed the "if" section
to one on general conditional functions. Added documentation for
$(and ...) and $(or ...) functions.
* NEWS: Note new $(and ...) and $(or ...) functions.
2006-02-08 Boris Kolpackov <boris@kolpackov.net>
* job.h (struct child): Add the dontcare bitfield.
* job.c (new_job): Cache dontcare flag.
* job.c (reap_children): Use cached dontcare flag instead of the
one in struct file. Fixes Savannah bug #15641.
2006-02-06 Paul D. Smith <psmith@gnu.org>
* vpath.c (selective_vpath_search): If the file we find has a
timestamp from -o or -W, use that instead of the real time.
* remake.c (f_mtime): If the mtime is a special token from -o or
-W, don't overwrite it with the real mtime.
Fixes Savannah bug #15341.
Updates from Markus Mauhart <qwe123@chello.at>:
* w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
(process_signal, process_last_err, process_exit_code): Manage
invalid handle values.

to avoid walking the list every time we want to add a new one.
Fixes Savannah bug #15533.
* filedef.h (struct file): Add a new LAST pointer.
* dir.c (directory_contents_hash_cmp): Don't use subtraction to do
the comparison. For 64-bits systems the result of the subtraction
might not fit into an int. Use comparison instead.
Fixes Savannah bug #15534.
* doc/make.texi: Update the chapter on writing commands to reflect
the changes made in 3.81 for backslash/newline and SHELL handling.
2006-02-01 Paul D. Smith <psmith@gnu.org>

* prepare_w32.bat: Remove this file from the distribution.
2006-01-21 Eli Zaretskii <eliz@gnu.org>
* remake.c (update_goal_chain): Set g->changed instead of
incrementing it, as it is only 8-bit wide, and could overflow if
many commands got started in update_file.
* w32/include/sub_proc.h: Add a prototype for process_used_slots.
* w32/subproc/sub_proc.c: Change dimension of proc_array[] to
MAXIMUM_WAIT_OBJECTS.

are already more children than sub_proc.c can handle, behave as if
the load were too high.
(start_job_command): Fix a typo in error message when process_easy
fails.
2006-01-14 Eli Zaretskii <eliz@gnu.org>
* main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
the shell is not sh.exe.
* job.c (create_batch_file): Renamed from create_batch_filename;
all callers changed. Don't close the temporary file; return its

handling of backslash-newline sequences. Mention the differences
on MS-DOS and MS-Windows.
* NEWS: More details about building the MinGW port and a pointer
to README.W32. Fix the section name that describes the new
backward-incompatible processing of backslash-newline sequences.
The special processing of SHELL set to "cmd" is only relevant to
MS-Windows, not MS-DOS.

garbage happened to be on the heap.
2005-12-12 Paul D. Smith <psmith@gnu.org>
* make.1: Fix some display errors and document all existing options.
Patch provided by Mike Frysinger <vapier@gentoo.org>.
2005-12-11 Paul D. Smith <psmith@gnu.org>

this implicit rule, replace the pattern with the stem directly,
and don't re-expand the variable list. Along with the other
.SECONDEXPANSION changes below, fixes bug #13781.
2005-12-09 Boris Kolpackov <boris@kolpackov.net>
* implicit.c (pattern_search): Mark other files that this rule
builds as targets so that they are not treated as intermediates
by the pattern rule search algorithm. Fixes bug #13022.
2005-12-07 Boris Kolpackov <boris@kolpackov.net>
* remake.c (notice_finished_file): Propagate the change of
modification time to all the double-colon entries only if
it is the last one to be updated. Fixes bug #14334.
2005-11-17 Boris Kolpackov <boris@kolpackov.net>

* read.c (record_files): Don't set deps flags if there are no deps.
* maintMakefile: We only need to build the templates when we are
creating a distribution, so don't do it for "all".
2005-10-24 Paul D. Smith <psmith@gnu.org>
Make secondary expansion optional: its enabled by declaring the
special target .SECONDEXPANSION.
* NEWS: Update information on second expansion capabilities.
* doc/make.texi (Secondary Expansion): Document the
.SECONDEXPANSION special target and its behavior.
* dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
prerequisite list was found in a static pattern rule.
(free_dep_chain): Declare a prototype.
* file.c (parse_prereqs): New function: break out some complexity
from expand_deps().
(expand_deps): If we aren't doing second expansion, replace % with
the stem for static pattern rules. Call the new function.
* filedef.h (parse_prereqs): Declare a prototype.

Set the staticpattern field for prereqs of static pattern targets.
2005-10-16 Paul D. Smith <psmith@gnu.org>
* main.c (main): Set CURDIR to be a file variable instead of a
default, so that values of CURDIR inherited from the environment
won't override the make value.
2005-09-26 Paul D. Smith <psmith@gnu.org>
* job.c (construct_command_argv_internal): If the line is empty
remember to free the temporary argv strings.
Fixes bug # 14527.
2005-09-16 Paul D. Smith <psmith@gnu.org>
* job.c (start_job_command): The noerror flag is a boolean (single
bit); set it appropriately.

seems to come in the wrong order. Try to force it with fflush().
2005-08-10 Boris Kolpackov <boris@kolpackov.net>
* read.c (record_files): Move code that sets stem for static
pattern rules out of the if (!two_colon) condition so it is
also executed for two-colon rules. Fixes Savannah bug #13881.
2005-08-08 Paul D. Smith <psmith@gnu.org>
* make.h: Don't test that __STDC__ is non-0. Some compilers
(Windows for example) set it to 0 to denote "ISO C + extensions".
Fixes bug # 13594.
2005-08-07 Paul D. Smith <psmith@gnu.org>
* w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
conditional (slightly different version of a fix from Eli).
Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
If make is running in parallel without -k and two jobs die in a
row, but not too close to each other, then make will quit without
waiting for the rest of the jobs to die.
* main.c (die): Don't reset err before calling reap_children() the
second time: we still want it to be in the error condition.
* job.c (reap_children): Use a static variable, rather than err,
to control whether or not the error message should be printed.
2005-08-06 Eli Zaretskii <eliz@gnu.org>

(reap_children) [WINDOWS32]: Get the handle for the main thread
and store it in main_thread.
* commands.c [WINDOWS32]: Include windows.h and w32err.h.
(fatal_error_signal) [WINDOWS32]: Suspend the main thread before
doing anything else. When we are done, close the main thread
handle and exit with status 130.

* w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
pointer to fprintf.

set sh_found and the value of default_shell, and report the
findings in debug mode.

no_default_sh_exe, to decide whether to use Unixy or DOSish
builtin commands.
* README.W32: Update with info about the MinGW build.

2005-07-15 Paul Smith <psmith@gnu.org>
* job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
we don't have a POSIX shell, then revert to the old
backslash-newline behavior (where they are stripped).
Fixes bug #13665.
2005-07-08 Paul D. Smith <psmith@gnu.org>
* config.h.W32.template: Reorder to match the standard config.h,
for easier comparisons.
From J. Grant <jg@jguk.org>

arithmetic to avoid a warning.
* main.c (switches): Add full-fledged final initializer.
2005-07-06 Paul D. Smith <psmith@gnu.org>

* signame.c (strsignal): If we found _sys_siglist[] or
__sys_siglist[] use those instead of sys_siglist[].
From Albert Chin <china@thewrittenword.com>
2005-07-04 Paul D. Smith <psmith@gnu.org>

declaration was checked but not present.
2005-06-27 Paul D. Smith <psmith@gnu.org>

Fixes Savannah bug #13551.
2005-06-26 Paul D. Smith <psmith@gnu.org>

"include" variants, don't print an error.
* doc/make.texi (Include): Document this.
Fixes Savannah bug #1761.
* job.c (construct_command_argv_internal): Sanitize handling of
backslash/newline pairs according to POSIX: that is, keep the
backslash-newline in the command script, but remove a following
TAB character, if present. In the fast path, make sure that the
behavior matches what the shell would do both inside and outside
of quotes. In the slow path, quote the backslash and put a
literal newline in the string.
Fixes Savannah bug #1332.
* doc/make.texi (Execution): Document the new behavior and give
some examples.
* NEWS: Make a note of the new behavior.
* make.h [WINDOWS32]: #include <direct.h>.
Fixes Savannah bug #13478.
* remake.c (name_mtime): If the stat() of a file fails and the -L
option was given and the file is a symlink, take the best mtime of
the symlink we can get as the mtime of the file and don't fail.
Fixes Savannah bug #13280.
* read.c (find_char_unquote): Accept a new argument IGNOREVARS.
If it's set, then don't stop on STOPCHARs or BLANKs if they're
inside a variable reference. Make this function static as it's
only used here.
(eval): Call find_char_unquote() with IGNOREVARS set when we're
parsing an unexpanded line looking for semicolons.
Fixes Savannah bug #1454.
* misc.c (remove_comments): Move this to read.c and make it static
as it's only used there. Call find_char_unquote() with new arg.
* make.h: Remove prototypes for find_char_unquote() and
remove_comments() since they're static now.
* main.c (main): If we see MAKE_RESTARTS in the environment, unset
its export flag and obtain its value. When we need to re-exec,
increment the value and add it into the environment.
* doc/make.texi (Special Variables): Document MAKE_RESTARTS.
* NEWS: Mention MAKE_RESTARTS.
* main.c (always_make_set): New variable. Change the -B option to
set this one instead.
(main): When checking makefiles, only set always_make_flag if
always_make_set is set AND the restarts flag is 0. When building
normal targets, set it IFF always_make_set is set.
(main): Avoid infinite recursion with -W, too: only set what-if
files to NEW before we check makefiles if we've never restarted
before. If we have restarted, set what-if files to NEW _after_ we
check makefiles.
Fixes Savannah bug #7566:
2005-06-17 Paul D. Smith <psmith@gnu.org>
* default.c: Change VMS implicit rules to use $$$$ instead of $$
in the prerequisites list.
2005-06-12 Paul D. Smith <psmith@gnu.org>
Fix Savannah bug # 1328.
* configure.in: Check for atexit().
* misc.c (close_stdout): Test stdout to see if writes to it have
failed. If so, be sure to exit with a non-0 error code. Based on
code found in gnulib.
* make.h: Prototype.
* main.c (main): Install close_stdout() with atexit().
2005-06-10 Paul D. Smith <psmith@gnu.org>
VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
* vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
headers; make vmsWaitForChildren() static; extern vmsify().
* job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
Don't create child_execute_job() here (it's in vmsjobs.c).
* makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
2005-06-09 Paul D. Smith <psmith@gnu.org>
* variable.c (push_new_variable_scope): File variables point
directly to the global_setlist variable. So, inserting a new
scope in front of that has no effect on those variables: they
don't go through current_variable_set_list. If we're pushing a
scope and the current scope is global, push it "the other way" so
that the new setlist is in the global_setlist variable, and
next points to a new setlist with the global variable set.
(pop_variable_scope): Properly undo a push with the new
semantics.
Fixes Savannah bug #11913.
2005-05-31 Boris Kolpackov <boris@kolpackov.net>
* job.c (reap_children): Don't die of the command failed but
the dontcare flag is set. Fixes Savannah bug #13216.
* implicit.c (pattern_search): When creating a target from
an implicit rule match, lookup pattern target and set precious
flag in a newly created target. Fixes Savannah bug #13218.
2005-05-13 Paul D. Smith <psmith@gnu.org>
Implement "if... else if... endif" syntax.
* read.c (eval): Push all checks for conditional words ("ifeq",
"else", etc.) down into the conditional_line() function.
(conditional_line): Rework to allow "else if..." clause. New
return value -2 for lines which are not conditionals. The
ignoring flag can now also be 2, which means "already parsed a
true branch". If that value is seen no other branch of this
conditional can be considered true. In the else parsing if there
is extra text after the else, invoke conditional_line()
recursively to see if it's another conditional. If not, it's an
error. If so, raise the conditional value to this level instead
of creating a new conditional nesting level. Special check for
"else" and "endif", which aren't allowed on the "else" line.
* doc/make.texi (Conditional Syntax): Document the new syntax.
2005-05-09 Paul D. Smith <psmith@gnu.org>
* Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
(MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
recurses to the w32 directory, even on non-Windows systems. Use
the method suggested in the automake manual.
* configure.in: Add w32/Makefile to AC_CONFIG_FILES.
* maintMakefile (gnulib-url): They moved the texinfo.tex files.
2005-05-07 Paul D. Smith <psmith@gnu.org>
* main.c (die): If we're dying with a fatal error (not that a
command has failed), write back any leftover tokens before we go.
* job.c (set_child_handler_action_flags): If there are jobs
waiting for the load to go down, set an alarm to go off in 1
second. This allows us to wake up from a potentially long-lasting
read() and start a new job if the load has gone down. Turn it off
after the read.
(job_noop): Dummy signal handler function.
(new_job): Invoke it with the new semantics.
* docs/make.texi: Document secondary expansion. Various cleanups
and random work.
2005-05-03 Paul D. Smith <psmith@gnu.org>
Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
the targets which are to ultimately be made are called "goals";
see the GNU make manual. Also, MAKECMDGOALS, etc.
* filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
.DEFAULT_GOAL, and default_target_name to default_goal_name.
* doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
2005-05-02 Paul D. Smith <psmith@gnu.org>
* job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
functions to vmsjobs.c. #include it into jobs.c.
Grant Taylor <gtaylor@picante.com> reports that -j# can lose
jobserver tokens. I found that this happens when an exported
recursive variable contains a $(shell ...) function reference: in
this situation we could "forget" to write back a token.
* job.c, job.h: Add variable jobserver_tokens: counts the tokens
we have. It's not reliable to depend on the number of children in
our linked list so keep a separate count.
(new_job): Check jobserver_tokens rather than children &&
waiting_jobs. Increment jobserver_tokens when we get one.
(free_child): If jobserver_tokens is 0, internal error. If it's
>1, write a token back to the jobserver pipe (we don't write a
token for the "free" job). Decrement jobserver_tokens.
* main.c: Add variable master_job_slots.
(main): Set it to hold the number of jobs requested if we're the
master process, when using the jobserver.
(die): Sanity checks: first test jobserver_tokens to make sure
this process isn't holding any tokens we didn't write back.
Second, if master_job_slots is set count the tokens left in the
jobserver pipe and ensure it's the same as master_job_slots (- 1).
2005-04-24 Paul D. Smith <psmith@gnu.org>
Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
with -l# can lose jobserver tokens, because waiting jobs are not
consulted properly when checking for the "free" token.
* job.c (free_child): Count waiting_jobs as having tokens.
* job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
handle jobs waiting for the load to drop.
2005-04-23 Paul D. Smith <psmith@gnu.org>
* main.c (main): Be careful to not core if a variable setting in
the environment doesn't contain an '='. This is illegal but can
happen in broken setups.
Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
2005-04-12 Paul D. Smith <psmith@gnu.org>
The second expansion feature causes significant slowdown. Timing
a complex makefile (GCC 4.1) shows a slowdown from .25s to just
read the makefile before the feature, to 11+s to do the same
operations after the feature. Additionally, memory usage
increased drastically. To fix this I added some intelligence that
avoids the overhead of the second expansion unless it's required.
* dep.h: Add a new boolean field, need_2nd_expansion.
* read.c (eval): When creating the struct dep for the target,
check if the name contains a "$"; if so set need_2nd_expansion to 1.
(record_files): If there's a "%" in a static pattern rule, it gets
converted to "$*" so set need_2nd_expansion to 1.
* file.c (expand_deps): Rework to be more efficient. Only perform
initialize_file_variables(), set_file_variables(), and
variable_expand_for_file() if the need_2nd_expansion is set.
* implicit.c (pattern_search): Default need_2nd_expansion to 0.
(pattern_search): Ditto.
* main.c (handle_non_switch_argument): Ditto.
(main): Ditto.
* read.c (read_all_makefiles): Ditto.
(eval_makefile): Ditto.
2005-04-07 Paul D. Smith <psmith@gnu.org>
* main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
* variable.c (sync_Path_environment): Ditto.
Patch by Alessandro Vesely. Fixes Savannah bug #12209.
* main.c (main): Define the .FEATURES variable.
* NEWS: Announce .FEATURES.
* doc/make.texi (Special Variables): Document .FEATURES.
* remake.c (check_dep): If a file is .PHONY, update it even if
it's marked intermediate. Fixes Savannah bug #12331.
2005-03-15 Boris Kolpackov <boris@kolpackov.net>
* file.c (expand_deps): Factor out the second expansion and
prerequisite line parsing logic from snap_deps().
* file.c (snap_deps): Use expand_deps(). Expand and parse
prerequisites of the .SUFFIXES special target first. Fixes
Savannah bug #12320.
2005-03-13 Paul D. Smith <psmith@gnu.org>
* main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
Zaretskii.
2005-03-11 Paul D. Smith <psmith@gnu.org>
* signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
available, not undefined (from Earnie Boyd).
2005-03-10 Boris Kolpackov <boris@kolpackov.net>
* implicit.c (pattern_search): Mark an intermediate target as
precious if it happened to be a prerequisite of some (other)
target. Fixes Savannah bug #12267.
2005-03-09 Paul D. Smith <psmith@gnu.org>
* read.c (eval_makefile): Add alloca(0).
(eval_buffer): Ditto.
2005-03-09 Boris Kolpackov <boris@kolpackov.net>
* main.c (main): Use o_file instead of o_default when defining
the .DEFAULT_TARGET special variable.
* read.c (eval): Use define_variable_global() instead of
define_variable() when setting new value for the .DEFAULT_TARGET
special variable. Fixes Savannah bug #12266.
2005-03-04 Boris Kolpackov <boris@kolpackov.net>
* imlicit.c (pattern_search): Mark files for which an implicit
rule has been found as targets. Fixes Savannah bug #12202.
2005-03-04 Paul D. Smith <psmith@gnu.org>
* AUTHORS: Update.
* doc/make.texi (Automatic Variables): Document $|.
2005-03-03 Boris Kolpackov <boris@kolpackov.net>
* read.c (record_files): Instead of substituting % with
actual stem value in dependency list replace it with $*.
This fixes stem triple expansion bug.
* implicit.c (pattern_search): Copy stem to a separate
buffer and make it a properly terminated string. Assign
this buffer instead of STEM (which is not terminated) to
f->stem. Instead of substituting % with actual stem value
in dependency list replace it with $*. This fixes stem
triple expansion bug.
2005-03-01 Paul D. Smith <psmith@gnu.org>
* commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
on Windows, as it takes a handle not a pid. Just exit.
Fix from patch #3679, provided by Alessandro Vesely.
* configure.in: Update check for sys_siglist[] from autoconf manual.
* signame.c (strsignal): Update to use the new autoconf macro.
2005-03-01 Boris Kolpackov <boris@kolpackov.net>
* read.c (record_files): Add a check for the list of prerequisites
of a static pattern rule being empty. Fixes Savannah bug #12180.
2005-02-28 Paul D. Smith <psmith@gnu.org>
* doc/make.texi (Text Functions): Update docs to allow the end
ordinal for $(wordlist ...) to be 0.
* function.c (func_wordlist): Fail if the start ordinal for
$(wordlist ...) is <1. Matches documentation.
Resolves Savannah support request #103195.
* remake.c (update_goal_chain): Fix logic for stopping in -q:
previously we were stopping when !-q, exactly the opposite. This
has been wrong since version 1.34, in 1994!
(update_file): If we got an error don't break out to run more
double-colon rules: just return immediately.
Fixes Savannah bug #7144.
2005-02-27 Paul D. Smith <psmith@gnu.org>
* misc.c (end_of_token): Make argument const.
* make.h: Update prototype.
* function.c (abspath, func_realpath, func_abspath): Use
PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
* dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
* read.c (record_files): Ditto.
* variable.c (do_variable_definition): Ditto.
* function.c (func_error): Create a new function $(info ...) that
simply prints the message to stdout with no extras.
(function_table_init): Add new function to the table.
* NEWS: Add $(info ...) reference.
* doc/make.texi (Make Control Functions): Document it.
New feature: if the system supports symbolic links, and the user
provides the -L/--check-symlink-time flag, then use the latest
mtime between the symlink(s) and the target file.
* configure.in (MAKE_SYMLINKS): Check for lstat() and
readlink(). If both are available, define MAKE_SYMLINKS.
* main.c: New variable: check_symlink_flag.
(usage): Add a line for -L/--check-symlink-times to the help string.
(switches): Add -L/--check-symlink-times command line argument.
(main): If MAKE_SYMLINKS is not defined but the user specified -L,
print a warning and disable it again.
* make.h: Declare check_symlink_flag.
* remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
if the file is a symlink then check each link in the chain and
choose the NEWEST mtime we find as the mtime for the file. The
newest mtime might be the file itself!
* NEWS: Add information about this new feature.
* doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
Avoid core dumps described in Savannah bug # 12124:
* file.c: New variable snapped_deps remember whether we've run
snap_deps().
(snap_deps): Set it.
* filedef.h: Extern it.
* read.c (record_files): Check snapped_deps; if it's set then
we're trying to eval a new target/prerequisite relationship from
within a command script, which we don't support. Fatal.
2005-02-28 Boris Kolpackov <boris@kolpackov.net>
Implementation of the .DEFAULT_TARGET special variable.
* read.c (eval): If necessary, update default_target_name when
reading rules.
* read.c (record_files): Update default_target_file if
default_target_name has changed.
* main.c (default_target_name): Define.
* main.c (main): Enter .DEFAULT_TARGET as make variable. If
default_target_name is set use default_target_file as a root
target to make.
* filedef.h (default_target_name): Declare.
* dep.h (free_dep_chain):
* misc.c (free_dep_chain): Change to operate on struct nameseq
and change name to free_ns_chain.
* file.c (snap_deps): Update to use free_ns_chain.
2005-02-27 Boris Kolpackov <boris@kolpackov.net>
Implementation of the second expansion in explicit rules,
static pattern rules and implicit rules.
* read.c (eval): Refrain from chopping up rule's dependencies.
Store them in a struct dep as a single dependency line. Remove
the code that implements SySV-style automatic variables.
* read.c (record_files): Adjust the code that handles static
pattern rules to expand all percents instead of only the first
one. Reverse the order in which dependencies are stored so that
when the second expansion reverses them again they appear in
the makefile order (with some exceptions, see comments in
the code). Remove the code that implements SySV-style automatic
variables.
* file.c (snap_deps): Implement the second expansion and chopping
of dependency lines for explicit rules.
* implicit.c (struct idep): Define an auxiliary data type to hold
implicit rule's dependencies after stem substitution and
expansion.
* implicit.c (free_idep_chain): Implement.
* implicit.c (get_next_word): Implement helper function for
parsing implicit rule's dependency lines into words taking
into account variable expansion requests. Used in the stem
splitting code.
* implicit.c (pattern_search): Implement the second expansion
for implicit rules. Also fixes bug #12091.
* commands.h (set_file_variables): Declare.
* commands.c (set_file_variables): Remove static specifier.
* dep.h (free_dep_chain): Declare.
* misc.c (free_dep_chain): Implement.
* variable.h (variable_expand_for_file): Declare.
* expand.c (variable_expand_for_file): Remove static specifier.
* make.h (strip_whitespace): Declare.
* function.c (strip_whitespace): Remove static specifier.
2005-02-26 Paul D. Smith <psmith@gnu.org>
* main.c (main): Check for ferror() when reading makefiles from stdin.
Apparently some shells in Windows don't close pipes properly and
require this check.
2005-02-24 Jonathan Grant <jg@jguk.org>
* configure.in: Add MinGW configuration options, and extra w32 code
directory.
* Makefile.am: Add MinGW configuration options, and extra w32 code
directory.
* main.c: Determine correct program string (after last \ without .exe).
* subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
type fix x2
* w32/Makefile.am: Import to build win32 lib of sub_proc etc.
* subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
* tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
environment support.
2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
* function.c (func_shell): When initializing error_prefix, check
that reading file name is not null. This fixes long-standing
segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
2005-02-09 Paul D. Smith <psmith@gnu.org>
* maintMakefile: Update the CVS download URL to simplify them.
Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
downloading the .texi files from Savannah now.
Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
* main.c (handle_non_switch_argument): Only add variables to
command_variables if they're not already there: duplicate settings
waste space and can be confusing to read.
* w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
this header is never included by non-WINDOWS32 code, and it
requires <config.h> to define which isn't always included first.
* dir.c (read_dirstream) [MINGW]: Use proper macro names when
testing MINGW32 versions.
* main.c (log_working_directory): flush stdout to be sure the WD
change is printed before any stderr messages show up.
2005-02-01 Paul D. Smith <psmith@gnu.org>
* maintMakefile (po_repo): Update the GNU translation site URL.
2004-12-01 Paul D. Smith <psmith@gnu.org>
* main.c (main): Change char* env_shell to struct variable shell_var.
* variable.c (target_environment): Use new shell_var.
2004-11-30 Paul D. Smith <psmith@gnu.org>
* configure.in: The old way we avoided creating build.sh from
build.sh.in before build.sh.in exists doesn't work anymore; we
have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
the help!). This also keeps automake from complaining.
* Makefile.am (README): Add a dummy target so automake won't
complain that this file doesn't exist when we checkout from CVS.
* maintMakefile (.dep_segment): Rewrite this rule since newer
versions of automake don't provide DEP_FILES.
2004-11-30 Boris Kolpackov <boris@kolpackov.net>
Implementation of `realpath' and `abspath' built-in functions.
* configure.in: Check for realpath.
* function.c (abspath): Return an absolute file name that does
not contain any `.' or `..' components, nor repeated `/'.
* function.c (func_abspath): For each name call abspath.
* function.c (func_realpath): For each name call realpath
from libc or delegate to abspath if realpath is not available.
* doc/make.texi (Functions for File Names): Document new functions.
* doc/make.texi (Quick Reference): Ditto.
2004-11-28 Paul D. Smith <psmith@gnu.org>
* main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
arguments. Fixes bug #10252.
Fix for bug #1276: Handle SHELL according to POSIX requirements.
* main.c (main): Set SHELL to v_noexport by default. Remember the
original environment setting of SHELL in the env_shell variable.
* main.h: Export new env_shell variable.
* variable.c (target_environment): If we find a v_noexport
variable for SHELL, add a SHELL variable with the env_shell value.
* doc/make.texi (Quick Reference): Document the POSIX behavior.
* doc/make.texi (Variables/Recursion): Ditto.
2004-11-28 Paul D. Smith <psmith@gnu.org>
* main.c (find_and_set_default_shell) [WINDOWS32]: check for
equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
Patch by Alessandro Vesely.
2004-11-12 Paul D. Smith <psmith@gnu.org>
* job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
the command line if it's inside a string.
Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
2004-10-21 Boris Kolpackov <boris@kolpackov.net>
* function.c (func_lastword): New function: return last word
from the list of words.
* doc/make.texi: Document $(lastword ). Fix broken links in
Quick Reference section.
2004-10-06 Paul D. Smith <psmith@gnu.org>
Apply patch from Alessandro Vesely, provided with bug # 9748.
Fix use of tmpnam() to work with Borland C.
* job.c (construct_command_argv_internal) [WINDOWS32]: Remove
construction of a temporary filename, and call new function
create_batch_filename().
(create_batch_filename) [WINDOWS32]: New function to create a
temporary filename.
2004-10-05 Boris Kolpackov <boris@kolpackov.net>
* read.c (record_target_var): Expand simple pattern-specific
variable.
* variable.c (initialize_file_variables): Do not expand simple
pattern-specific variable.
2004-09-28 Boris Kolpackov <boris@kolpackov.net>
* remake.c (update_file_1): When rebuilding makefiles inherit
dontcare flag from a target that triggered update.
2004-09-27 Boris Kolpackov <boris@kolpackov.net>
* variable.c (initialize_file_variables): Mark pattern-specific
variable as a per-target and copy export status.
2004-09-21 Boris Kolpackov <boris@kolpackov.net>
* file.c (snap_deps): Mark .PHONY prerequisites as targets.
* implicit.c (pattern_search): When considering an implicit rule's
prerequisite check that it is actually a target rather then
just an entry in the file hashtable.
2004-09-21 Paul D. Smith <psmith@gnu.org>
* read.c (readstring): Fix some logic errors in backslash handling.
(eval): Remove some unnecessary processing in buffer handling.
(record_target_var): Assert that parse_variable_definition() succeeded.
Reported by: Markus Mauhart <qwe123@chello.at>.
* misc.c: Removed the sindex() function. All instances of this
function were trivially replaceable by the standard strstr()
function, and that function will always have better (or certainly
no worse) performance than the very simple-minded algorithm
sindex() used. This can matter with complex makefiles.
* make.h: Remove the prototype for sindex().
* function.c (subst_expand): Convert sindex() call to strstr().
This means we no longer need to track the TLEN value so remove that.
(func_findstring): Convert sindex() to strstr().
* commands.c (chop_commands): Convert sindex() calls to strstr().
Suggested by: Markus Mauhart <qwe123@chello.at>.
* main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
idea behind Savannah Patch #3144 from david.baird@homemail.com.
If SHELL is set to CMD.EXE then assume it's batch-mode and
non-unixy. I wrote the code differently from the patch, though,
to make it safer. This also resolves bug #9174.
2004-09-20 Paul D. Smith <psmith@gnu.org>
* expand.c (variable_expand_string): Modify to invoke
patsubst_expand() instead of subst_expand(); the latter didn't
handle suffix patterns correctly.
* function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
was used only from variable_expand_string() and is no longer used
there.
(func_subst): Ditto, on call to subst_expand().
(patsubst_expand): Require the percent pointers to point to the
character after the %, not to the % itself.
* read.c (record_files): New call criteria for patsubst_expand().
* variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
2004-09-19 Paul D. Smith <psmith@gnu.org>
* function.c (subst_expand): Fix a check in by_word: look for a
previous blank if we're beyond the beginning of the string, not
the beginning of the word.
Bugs reported by Markus Mauhart <qwe123@chello.at>.
2004-05-16 Paul D. Smith <psmith@gnu.org>
* remake.c (update_goal_chain): Change the argument specifying
whether we're rebuilding makefiles to be a global variable,
REBUILDING_MAKEFILES.
(complain): Extract the code that complains about no rules to make
a target into a separate function.
(update_file_1): If we tried to rebuild a file during the makefile
rebuild phase and it was dontcare, then no message was printed.
If we then try to build the same file during the normal build,
print a message this time.
(remake_file): Don't complain about un-remake-able files when
we're rebuilding makefiles.
2004-05-11 Paul D. Smith <psmith@gnu.org>
* job.c (construct_command_argv_internal): OS/2 patches from
Andreas Buening <andreas.buening@nexgo.de>.
2004-05-10 Paul D. Smith <psmith@gnu.org>
* remake.c (update_file): Don't walk the double-colon chain unless
this is a double-colon rule. Fix suggested by Boris Kolpackov
<boris@kolpackov.net>.
* makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
* readme.vms: New section describing OpenVMS support and issues.
* default.c (default_variables): Add support for IA64.
* job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
without some privilege aborts make with the error
%SYSTEM-F-NOPRIV. It happens when setting up a handler for
pressing Ctrl+Y and the input device is no terminal. The change
catches this error and just continues.
Patches by Hartmut Becker <Hartmut.Becker@hp.com>
2004-04-25 Paul D. Smith <psmith@gnu.org>
* commands.c (set_file_variables): Set $< properly in the face of
order-only prerequisites.
Patch from Boris Kolpackov <boris@kolpackov.net>
2004-04-21 Bob Byrnes <byrnes@curl.com>
* main.c (main): Notice failures to remake makefiles.
2004-03-28 Paul D. Smith <psmith@gnu.org>
Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
* job.c: No default shell for RISC OS.
(load_too_high): Hard-code the return to 1.
(construct_command_argv_internal): No sh_chars or sh_cmds.
* getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
2004-03-20 Paul D. Smith <psmith@gnu.org>
* variable.c (do_variable_definition): Don't append from the
global set if a previous non-appending target-specific variable
definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
(with fix).
* expand.c (reference_variable): Don't give up on variables with
no value that have the target-specific append flag set: they might
have a value after all. Reported by Oliver Schmidt
<oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
<nikulin@dx1cmd.inp.nsk.su>.
* rule.c (count_implicit_rule_limits): Don't delete patterns which
refer to absolute pathnames in directories that don't exist: some
portion of the makefile could create those directories before we
match the pattern. Fixes bugs #775 and #108.
Fixes from Jonathan R. Grant <jg-make@jguk.org>:
* main.c (main): Free makefile_mtimes if we have any.
* README.W32.template: Update documentation for the current status
of the MS-Windows port.
* NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
environment variable is sometimes already defined which causes the
build to fail.
* main.c (debug_signal_handler): Only define this function if
SIGUSR1 is available.
Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
* configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
* README.OS2.template: Documentation updates.
* build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
link line for safety.
* maintMakefile (build.sh.in): Remove an extraneous ")".
* job.c (child_execute_job): Close saved FDs.
* job.c (exec_command) [OS/2]: exec_command(): If the command
can't be exec'ed and if the shell is not Unix-sh, then try again
with argv = { "cmd", "/c", ... }. Normally, this code is never
reached for the cmd shell unless the command really doesn't exist.
(construct_command_argv_internal) [OS/2]: The code for cmd
handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
The CMD builtin commands are case insensitive so use strcasecmp().
2004-03-19 Paul D. Smith <psmith@gnu.org>
* read.c (do_define): Re-order line counter increment so the count
is accurate (we were losing one line per define). Reported by
Dave Yost <Dave@Yost.com>.
2004-03-06 Paul D. Smith <psmith@gnu.org>
* configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
compiler.
* make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
* misc.c (message,error,fatal): Ditto.
* configh.dos.template: Define HAVE_ANSI_COMPILER.
* config.h.W32.template: Ditto.
* config.h-vms.template: Ditto.
* config.ami.template: Ditto.
2004-03-04 Paul D. Smith <psmith@gnu.org>
* README.template: Add a note about broken /bin/sh on SunOS
4.1.3_U1 & 4.1.4. Fix up Savannah links.
* misc.c (message, error, fatal): Don't use "..." if we're using
varargs. ansi2knr should handle this but it doesn't work: it
translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
done. On many systems (SunOS for example) va_dcl is a #define.
So, force the use of the non-"..." version on pre-ANSI compilers.
* maintMakefile (sign-dist): Create some rules to help automate
the new GNU ftp upload method.
2004-02-24 Paul D. Smith <psmith@gnu.org>
* config.h.W32.template: Add HAVE_STDARG_H
* config.h-vms.template: Ditto.
* config.ami.template: Ditto.
2004-02-23 Jonathan Grant <jg-make@jguk.org>
* README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
* build_w32.bat: Remove extra "+".
2004-02-23 Paul D. Smith <psmith@gnu.org>
* make.h: Create an UNUSED macro to mark unused parameters.
* (many): Clean up warnings by applying UNUSED, fixing
signed/unsigned incompatibilities, etc.
* acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
autoconf warnings.
* filedef.h: Name the command_state enumeration.
* file.c (set_command_state): Use the enumeration in the function
argument.
* configure.in: Explicitly set SET_MAKE to empty, to disable
MAKE=make even when no make already exists. Fix bug #3823.
2004-02-22 Paul D. Smith <psmith@gnu.org>
* maintMakefile: Perl script to clean up all non-CVS files. Use
it on all the subdirectories for the cvs-clean target.
* main.c (decode_switches): Require non-empty strings for all our
string command-line options. Fixes Debian bug # 164165.
* configure.in: Check for stdarg.h and varargs.h.
* make.h (USE_VARIADIC): Set this if we can use variadic functions
for printing messages.
* misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
(message): Ditto.
(error): Ditto.
(fatal): Ditto.
A number of patches for OS/2 support from Andreas Buening
<andreas.buening@nexgo.de>:
* job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
disable the SIGCHLD handler.
(reap_children) [OS/2]: Remove special handling of job_rfd.
(set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
(new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
* main.c (main) [OS/2]: Special handling for paths in OS/2.
* configure.in [OS/2]: Force SA_RESTART for OS/2.
* Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
systems.
2004-02-21 Paul D. Smith <psmith@gnu.org>
* w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
<mail@kristov.de> reports that if process_begin() fails we don't
handle the error condition correctly in all cases.
* w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
to have a newline on the message.
* job.c (construct_command_argv_internal): Add "test" to UNIX
sh_cmds[]. Fixes Savannah bug # 7606.
2004-02-04 Paul D. Smith <psmith@gnu.org>
* job.c (vms_handle_apos) [VMS]: Fix various string handling
situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
Hartmut Becker <Hartmut.Becker@hp.com>.
2004-01-21 Paul D. Smith <psmith@gnu.org>
* job.c (load_too_high): Implement an algorithm to control the
"thundering herd" problem when using -l to control job creation
via the load average. The system only recomputes the load once a
second but we can start many jobs in a second. To solve this we
keep track of the number of jobs started in the last second and
apply a weight to try to guess what a correct load would be.
The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
Also fixes bug #4693.
(reap_children): Decrease the job count for this second.
(start_job_command): Increase the job count for this second.
* read.c (conditional_line): Expand the text after ifn?def before
checking to see if it's a single word. Fixes bug #7257.
2004-01-09 Paul D. Smith <psmith@gnu.org>
* file.c (print_file): Recurse to print all targets in
double-colon rules. Fixes bug #4518, reported (with patch) by
Andrew Chatham <chatham@google.com>.
2004-01-07 Paul D. Smith <psmith@gnu.org>
* acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
* configure.in: Change make_FUNC_SETVBUF_REVERSED to
AC_FUNC_SETVBUF_REVERSED.
* doc/make.texi (Target-specific): Fix Savannah bug #1772.
(MAKE Variable): Fix Savannah bug #4898.
* job.c (construct_command_argv_internal): Add "!" to the list of
shell escape chars. POSIX sh allows it to appear before a
command, to negate the exit code. Fixes bug #6404.
* implicit.c (pattern_search): When matching an implicit rule,
remember which dependencies have the ignore_mtime flag set.
Original fix provided in Savannah patch #2349, by Benoit
Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2003-11-22 Paul D. Smith <psmith@gnu.org>
* README.W32.template (Outputs): Clarification on -j with
BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
<jg-make@jguk.org>.
2003-11-02 Paul D. Smith <psmith@gnu.org>
* function.c (func_if): Strip all the trailing whitespace from the
condition, then don't expand it. Fixed bug # 5798.
* expand.c (recursively_expand_for_file): If we're expanding a
variable with no file context, then use the variable's context.
Fixes bug # 6195.
2003-10-21 Paul D. Smith <psmith@gnu.org>
* main.c (log_working_directory): Add newlines to printf()s.
* README.cvs: Add a note to ignore warnings during autoreconf.
* maintMakefile (po_repo): Set a new URL for PO file updates.
(get-config/config.guess get-config/config.sub): Get these files
from the Savannah config project instead of ftp.gnu.org.
2003-10-05 Paul Eggert <eggert@twinsun.com>
* main.c (main): Avoid potential subscript error if environ has
short strings.
2003-08-22 Paul D. Smith <psmith@gnu.org>
* misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
systems which don't yet implement the C89 standard :-/.
2003-07-18 Paul D. Smith <psmith@gnu.org>
* dir.c (directory_contents_hash_1, directory_contents_hash_1)
[WINDOWS32]: Initialize hash.
2003-06-19 Earnie Boyd <earnie@uses.sf.net>
* dir.c (read_dirstream): Provide a workaround for broken versions of
the MinGW dirent structure.
2003-05-30 Earnie Boyd <earnie@users.sf.net>
* w32/include/dirent.h: Add __MINGW32__ filter.
2003-05-30 Earnie Boyd <earnie@users.sf.net>
* make.h: Add global declaration of *make_host.
* main.c (print_usage): Remove local declaration of *make_host.
(print_version): Display "This program built for ..." after Copyright
notice.
2003-05-30 Earnie Boyd <earnie@users.sf.net>
* doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
execution of "makeinfo --html make.texi".
2003-04-30 Paul D. Smith <psmith@gnu.org>
* build.template: Make some changes to maybe allow this script to
work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
* README.OS2.template: New file for OS/2 support. Original
contributed by Andreas Buening.
* configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
DOS-style paths.
2003-04-19 Paul D. Smith <psmith@gnu.org>
Fix bug #1405: allow a target to match multiple pattern-specific
variables.
* rule.c (create_pattern_var, lookup_pattern_var): Move these to
variable.c, where they've always belonged.
* rule.h: Move the prototypes and struct pattern_var as well.
* variable.c (initialize_file_variables): Invoke
lookup_pattern_var() in a loop, until no more matches are found.
If a match is found, create a new variable set for the target's
pattern variables. Then merge the contents of each matching
pattern variable set into the target's pattern variable set.
(lookup_pattern_var): Change this function to be usable
in a loop. It takes a starting position: if NULL, start at the
beginning; if non-NULL, start with the pattern variable after that
position, and return the next matching pattern.
(create_pattern_var): Create a unique instance of
pattern-specific variables for every definition in the makefile.
Don't combine the same pattern together. This allows us to
process the variable handling properly even when the same pattern
is used multiple times.
(parse_variable_definition): New function: break out the parsing
of a variable definition line from try_variable_definition.
(try_variable_definition): Call parse_variable_definition to
parse.
(print_variable_data_base): Print out pattern-specific variables.
* variable.h (struct variable): Remember when a variable is
conditional. Also remember its flavor.
(struct pattern_var): Instead of keeping a variable set, we just
keep a single variable for each pattern.
* read.c (record_target_var): Each pattern variable contains only a
single variable, not a set, so create it properly.
* doc/make.texi (Pattern-specific): Document the new behavior.
2003-04-17 Paul D. Smith <psmith@gnu.org>
* dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
file/directory naming rules for VMS so I can't tell whether this
is correct or not.
2003-04-09 Paul D. Smith <psmith@gnu.org>
* configure.in (HAVE_DOS_PATHS): Define this on systems that need
DOS-style pathnames: backslash separators and drive specifiers.
2003-03-28 Paul D. Smith <psmith@gnu.org>
* file.c (snap_deps): If .SECONDARY with no targets is given, set
the intermediate flag on all targets. Fixes bug #2515.
2003-03-24 Paul D. Smith <psmith@gnu.org>
* configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
Upgrade to autoconf 2.57 and automake 1.7.3.
* job.c: More OS/2 changes from Andreas Buening.
* file.c (print_file): Fix variable initialization.
Fixes bug #2892.
* remake.c (notice_finished_file):
* make.h (ENULLLOOP): Set errno = 0 before invoking the command;
some calls (like readdir()) return NULL in valid situations
without resetting errno. Fixes bug #2846.
2003-02-25 Paul D. Smith <psmith@gnu.org>
Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
* job.c (_is_unixy_shell) [OS/2]: New function.
Set default shell to /bin/sh.
(reap_children): Close the job_rfd pipe here since we don't use a
SIGCHLD handler.
(set_child_handler_action_flags): define this to empty on OS/2.
(start_job_command): Close the jobserver pipe and use
child_execute_job() instead of fork/exec.
(child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
rather than exec'ing, then reconfigure stdin/stdout.
(exec_command): Rewrite to use spawn instead of exec. Return the
PID of the child.
* main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
in DOS. Handle the TEMP environment variable as in DOS. Don't
use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
use -j in DOS mode. Use child_execute_job() instead of
exec_command().
* function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
spawn() instead.
* job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
prototypes that return values.
* remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
* read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
* default.c (default_suffixes) [OS/2]: Set proper default suffixes
for OS/2.
* vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
DOS paths.
2003-02-24 Paul D. Smith <psmith@gnu.org>
* default.c [VMS]: New default rules for .cxx -> .obj compiles.
* job.c (child_execute_job) [VMS]: New code for handling spawn().
(child_execute_job) [VMS]: Handle error status properly.
Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
* function.c (func_shell): Use EINTRLOOP() while reading from the
subshell pipe (Fixes bug #2502).
* job.c (free_child): Use EINTRLOOP() while writing tokens to the
jobserver pipe.
* main.c (main): Ditto.
2003-01-30 Paul D. Smith <psmith@gnu.org>
* read.c (eval): eval() was not fully reentrant, because the
collapsed buffer was static. Change it to be an automatic
variable so that eval() can be invoked recursively.
Fixes bug # 2238.
(eval): Apply patch # 1022: fix memory reference error on long
target-specific variable lines.
Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
* function.c (check_numeric): Combine the is_numeric() function
into this function, since it's only called from one place.
Constify this function. Have it print the incorrect string in the
error message. Fixes bug #2407.
(strip_whitespace): Constify.
(func_if): Constify.
* expand.c (expand_argument): Constify.
2003-01-29 Paul D. Smith <psmith@gnu.org>
Fix bug # 2169, also reported by other people on various systems.
* make.h: Some systems, such as Solaris and PTX, do not fully
implement POSIX-compliant SA_RESTART functionality; important
system calls like stat() and readdir() can still fail with EINTR
even if SA_RESTART has been set on the signal handler. So,
introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
EINTR for system calls which return -1 or 0 (NULL), respectively,
on error.
Also, remove the old atomic_stat()/atomic_readdir() and
HAVE_BROKEN_RESTART handling.
* configure.in: Remove setting of HAVE_BROKEN_RESTART.
* arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
* remake.c (touch_file): Ditto.
* commands.c (delete_target): Use EINTRLOOP() to wrap stat().
* read.c (construct_include_path): Ditto.
* remake.c (name_mtime): Ditto.
* vpath.c (selective_vpath_search): Ditto.
* dir.c (find_directory): Ditto.
(local_stat): Ditto.
(find_directory): Use ENULLLOOP() to wrap opendir().
(dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
* misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
atomic_readdir() handling.
2003-01-22 Paul D. Smith <psmith@gnu.org>
* function.c (func_call): Fix Bug #1744. If we're inside a
recursive invocation of $(call ...), mask any of the outer
invocation's arguments that aren't used by this one, so that this
invocation doesn't "inherit" them accidentally.
2002-12-05 Paul D. Smith <psmith@gnu.org>
* function.c (subst_expand): Valery Khamenia reported a
pathological performance hit when doing substitutions on very
large values with lots of words: turns out we were invoking
strlen() a ridiculous number of times. Instead of having each
call to sindex() call strlen() again, keep track of how much of
the text we've seen and pass the length to sindex().
2002-11-19 Paul D. Smith <psmith@gnu.org>
* README.cvs, configure.in: Upgrade to require autoconf 2.56.
2002-11-16 Paul D. Smith <psmith@gnu.org>
* NMakefile.template (OBJS): Add hash.c object file.
* SMakefile.template (srcs): Ditto.
* Makefile.ami (objs): Ditto.
* build_w32.bat: Ditto.
* Makefile.DOS.template: Remove extra dependencies.
2002-10-25 Paul D. Smith <psmith@gnu.org>
* expand.c (install_variable_buffer): New function. Install a new
variable_buffer context and return the previous one.
(restore_variable_buffer): New function. Free the current
variable_buffer context and put a previously saved one back.
* variable.h: Prototypes for {install,restore}_variable_buffer.
* function.c (func_eval): Push a new variable_buffer context
before we eval, then restore the old one when we're done.
Fixes Bug #1517.
* read.c (install_conditionals): New function. Install a new
conditional context and return the previous one.
(restore_conditionals): New function. Free the current
conditional context and put a previously saved one back.
(eval): Use the {install,restore}_conditionals for "include"
handling.
(eval_buffer): Use {install,restore}_conditionals to preserve the
present conditional state before we evaluate the buffer.
Fixes Bug #1516.
* doc/make.texi (Quick Reference): Add references to $(eval ...)
and $(value ...).
(Recursion): Add a variable index entry for CURDIR.
* README.cvs: Update to appropriate versions.
* Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
don't need to copy loadavg.c: automake is smart enough to create
it for me. Still have a bug in automake related to ansi2knr tho.
2002-10-14 Paul D. Smith <psmith@gnu.org>
* remake.c (notice_finished_file): Only touch targets if they have
at least one command (as per POSIX). Resolve Bug #1418.
* *.c: Convert to using ANSI C-style function definitions.
* Makefile.am: Enable the ansi2knr feature of automake.
* configure.in: ditto.
2002-10-13 Paul D. Smith <psmith@gnu.org>
* commands.c (set_file_variables): Bug #1379: Don't use alloca()
for automatic variable values like $^, etc. In the case of very
large lists of prerequisites this causes problems. Instead reuse
a static buffer (resizeable) for each variable.
* read.c (eval): Fix Bug #1391: allow "export" keyword in
target-specific variable definitions. Check for it and set an
"exported" flag.
(record_target_var): Set the export field to v_export if the
"exported" flag is set.
* doc/make.texi (Target-specific): Document the ability to use
"export".
* doc/make.texi: Change the name of the section on automatic
variables from "Automatic" to "Automatic Variables". Added text
clarifying the scope of automatic variables.
2002-10-04 Paul D. Smith <psmith@gnu.org>
* read.c (eval): Allow SysV $$@ variables to use {} braces as well
as () braces.
(record_files): Ditto.
* expand.c (variable_expand_string): In $(A:x=y) expansion limit
the search for the '=' to only within the enclosing parens.
2002-10-03 Paul D. Smith <psmith@gnu.org>
Version 3.80 released.
* dir.c: Change hash functions to use K&R function definition style.
* function.c: Ditto.
* read.c: Ditto.
* variable.c: Ditto.
Update to automake 1.7.
* Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
(pdf): Remove this target as automake now provides one.
* configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2002-09-30 Martin P.J. Zinser <zinser@decus.de>
* makefile.com: Updates for GNU make 3.80.
* makefile.vms: Ditto.
2002-09-23 Paul D. Smith <psmith@gnu.org>
* read.c (enum make_word_type): Remove w_comment.
(get_next_mword): Don't treat comment characters as special; where
this function is used we will never see a comment (it's stripped
before we get here) and treating comments specially means that
targets like "foo\#bar" aren't handled properly.
2002-09-18 Paul D. Smith <psmith@gnu.org>
* doc/make.texi (Bugs): Update with some info on Savannah, etc.
* read.c (eval): Expansion of arguments to export/unexport was
ignoring all arguments after the first one. Change the algorithm
to expand the whole line once, then parse the results.
2002-09-17 Paul D. Smith <psmith@gnu.org>
Fix Bug #940 (plus another bug I found while looking at this):
* read.c (record_target_var): enter_file() will add a new entry if
it's a double-colon target: we don't want to do that in this
situation. Invoke lookup_file() and only enter_file() if it does
not already exist. If the file we get back is a double-colon then
add this variable to the "root" double-colon target.
* variable.c (initialize_file_variables): If this file is a
double-colon target but is not the "root" target, then initialize
the root and make the root's variable list the parent of our
variable list.
2002-09-13 Paul D. Smith <psmith@gnu.org>
* doc/make.texi (MAKE Variable): Add some indexing for "+".
* hash.c (round_up_2): Get rid of a warning.
2002-09-12 Paul D. Smith <psmith@gnu.org>
* Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
so it doesn't complain about getloadavg.c.
* commands.c (set_file_variables): Make sure we always alloca() at
least 1 character for the value of $? (for '\0').
2002-09-11 Paul D. Smith <psmith@gnu.org>
* hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
macro to use RESULT instead of the incorrect _RESULT_.
* make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
and atomic_readdir(). We need to #include dirent.h to get this to
work.
* misc.c (atomic_readdir): Fix typos.
2002-09-10 Paul D. Smith <psmith@gnu.org>
* read.c (eval): Expand variable lists given to export and
unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
(conditional_line): Ditto for "ifdef". Fixes bug #103.
* doc/make.texi (Variables/Recursion): Document this.
(Conditional Syntax): And here.
2002-09-09 Paul D. Smith <psmith@gnu.org>
* configure.in: Check for memmove().
2002-09-07 Paul D. Smith <psmith@gnu.org>
* configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
Michael Sterrett <msterret@coat.com> reports that while it has
SA_RESTART, it does not work properly.
* misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
that invokes stat() and loops to do it again if it returns EINTR.
(atomic_readdir): Ditto, with readdir().
* make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
and readdir() to atomic_stat() and atomic_readdir().
2002-09-04 Paul D. Smith <psmith@gnu.org>
* implicit.c (pattern_search): Daniel <barkalow@reputation.com>
reports that GNU make sometimes doesn't recognize that targets can
be made, when directories can be created as prerequisites. He
reports that changing the order of predicates in the DEP->changed
flag test so that lookup_file() is always performed, solves this
problem.
2002-08-08 Paul D. Smith <psmith@gnu.org>
* configure.in: Require a newer version of gettext.
* misc.c (perror_with_name): Translate the format string (for
right-to-left language support).
(pfatal_with_name): Ditto.
* main.c: Create a static array of strings to store the usage
text. This is done to facilitate translations.
(struct command_switch): Remove argdesc and description fields.
(switches): Remove values for obsolete fields.
(print_usage): Print each element of the usage array.
* hash.c: Change function definitions to be K&R style.
2002-08-02 Paul D. Smith <psmith@gnu.org>
* NEWS: Remove the mention of .TARGETS; we aren't going to publish
this one because it's too hard to get right. We'll look at it for
a future release.
* main.c (main): Don't create the .TARGETS variable.
* variable.c (handle_special_var): Don't handle .TARGETS.
2002-08-01 Paul D. Smith <psmith@gnu.org>
* main.c (switches): Add a new option, -B (--always-make). If
specified, make will rebuild all targets that it encounters even
if they don't appear to be out of date.
(always_make_flag): New flag.
* make.h: Extern always_make_flag.
* remake.c (update_file_1): Check always_make_flag; if it's set we
will always rebuild any target we can, even if none of its
prerequisites are newer.
* NEWS: Mention it.
* doc/make.texi (Shell Function): Make it clear that make
variables marked as "export" are not passed to instances of the
shell function.
Add new introspection variable .VARIABLES and .TARGETS.
* variable.c (handle_special_var): New function. If the variable
reference passed in is "special" (.VARIABLES or .TARGETS),
calculate the new value if necessary. .VARIABLES is handled here:
walk through the hash of defined variables and construct a value
which is a list of the names. .TARGETS is handled by
build_target_list().
(lookup_variable): Invoke handle_special_var().
* file.c (build_target_list): Walk through the hask of known files
and construct a list of the names of all the ones marked as
targets.
* main.c (main): Initialize them to empty (and as simple variables).
* doc/make.texi (Special Variables): Document them.
* NEWS: Mention them.
* variable.h (struct variable): Add a new flag "exportable" which
is true if the variable name is valid for export.
* variable.c (define_variable_in_set): Set "exportable" when a new
variable is defined.
(target_environment): Use the "exportable" flag instead of
re-checking the name here... an efficiency improvement.
2002-07-31 Paul D. Smith <psmith@gnu.org>
* config.h-vms.template: Updates to build on VMS. Thanks to
Brian_Benning@aksteel.com for helping verify the build.
* makefile.com: Build the new hash.c file.
* hash.h: Use strcpmi(), not stricmp(), in the
HAVE_CASE_INSENSITIVE_FS case.
2002-07-30 Paul D. Smith <psmith@gnu.org>
* hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
backslashes to the HAVE_CASE_INSENSITIVE_FS case.
Reported by <Brian_Benning@aksteel.com>.
2002-07-10 Paul D. Smith <psmith@gnu.org>
* variable.c (pop_variable_scope): Remove variable made unused by
new hash infrastructure.
* read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
comparisons as well as name comparisons.
* variable.h: Add a prototype for new hash_init_function_table().
* file.c (lookup_file): Remove variables made unused by new hash
infrastructure.
* dir.c (directory_contents_hash_2): Missing return of hash value.
(dir_contents_file_exists_p): Remove variables made unused by new
hash infrastructure.
Installed Greg McGary's integration of the hash functions from the
GNU id-utils package:
2002-07-10 Greg McGary <greg@mcgary.org>
* scripts/functions/filter-out: Add literals to to the
pattern space in order to add complexity, and trigger
use of an internal hash table. Fix documentation strings.
* scripts/targets/INTERMEDIATE: Reverse order of files
passed to expected `rm' command.
2002-07-10 Greg McGary <greg@mcgary.org>

(print_variable_set): Likewise.
2002-07-10 Paul D. Smith <psmith@gnu.org>
Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
prerequisite list. A real SysV make will expand the entire
prerequisites list _twice_: we don't do that as it's a big
backward-compatibility problem. We only replace those specific
variables.
* read.c (record_files): Replace any $@, $(@D), and $(@F) variable
references left in the list of prerequisites. Check for .POSIX as
we record targets, so we can disable non-POSIX behavior while
reading makefiles as well as running them.
(eval): Check the prerequisite list to see if we have anything
that looks like a SysV prerequisite variable reference.
2002-07-09 Paul D. Smith <psmith@gnu.org>
* doc/make.texi (Prerequisite Types): Add a new section describing
order-only prerequisites.
* read.c (uniquize_deps): If we have the same file as both a
normal and order-only prereq, get rid of the order-only prereq,
since the normal one supersedes it.
2002-07-08 Paul D. Smith <psmith@gnu.org>
* AUTHORS: Added Greg McGary to the AUTHORS file.
* NEWS: Blurbed order-only prerequisites.
* file.c (print_file): Show order-only deps properly when printing
the database.
* maintMakefile: Add "update" targets for wget'ing the latest
versions of various external files. Taken from Makefile.maint in
autoconf, etc.
* dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2002-07-07 Paul D. Smith <psmith@gnu.org>
* po/*.po: Remove. We'll use wget to retrieve them at release
time.
* variable.c (do_variable_definition) [W32]: On W32 using cmd
rather than a shell you get an exception. Make sure we look up
the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
* remake.c (notice_finished_file): Fix handling of -t flag.
Patch provided by Henning Makholm <henning@makholm.net>.
* implicit.c (pattern_search): Some systems apparently run short
of stack space, and using alloca() in this function caused an
overrun. I modified it to use xmalloc() on the two variables
which seemed like they might get large. Fixes Bug #476.
* main.c (print_version): Update copyright notice to conform with
GNU standards.
(print_usage): Update help output.
* function.c (func_eval): Create a new make function, $(eval
...). Expand the arguments, put them into a buffer, then invoke
eval_buffer() on the resulting string.
(func_quote): Create a new function, $(quote VARNAME). Inserts
the value of the variable VARNAME without expanding it any
further.
* read.c (struct ebuffer): Change the linebuffer structure to an
"eval buffer", which can be either a file or a buffer.
(eval_makefile): Move the code in the old read_makefile() which
located a makefile into here: create a struct ebuffer with that
information. Have it invoke the new function eval() with that
ebuffer.
(eval_buffer): Create a new function that creates a struct ebuffer
that holds a string buffer instead of a file. Have it invoke
eval() with that ebuffer.
(eval): New function that contains the guts of the old
read_makefile() function: this function parses makefiles. Obtains
data to parse from the provided ebuffer. Some modifications to
make the flow of the function cleaner and clearer. Still could
use some work here...
(do_define): Takes a struct ebuffer instead of a FILE*. Read the
contents of the define/endef variable from the ebuffer.
(readstring): Read the next line from a string-style ebuffer.
(readline): Read the next line from an ebuffer. If it's a string
ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
from the file.
* dep.h (eval_buffer): Prototype eval_buffer();
* variable.c (do_variable_definition): Make sure that all
non-target-specific variables are registered in the global set.
If we're invoked from an $(eval ...) we might be inside a $(call
...) or other function which has pushed a variable scope; we still
want to define our variables from evaluated makefile code in the
global scope.
2002-07-03 Greg McGary <greg@mcgary.org>
* dep.h (struct dep) [ignore_mtime]: New member.
[changed]: convert to a bitfield.
* implicit.c (pattern_search): Zero ignore_mtime.
* main.c (main, handle_non_switch_argument): Likewise.
* rule.c (convert_suffix_rule): Likewise.
* read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
(read_makefile): Parse '|' in prerequisite list.
(uniquize_deps): Consider ignore_mtime when comparing deps.
* remake.c (update_file_1, check_dep): Don't force remake for
dependencies that have d->ignore_mtime.
* commands.c (FILE_LIST_SEPARATOR): New constant.
(set_file_variables): Don't include a
prerequisite in $+, $^ or $? if d->ignore_mtime.
Define $|.
2002-06-18 Paul D. Smith <psmith@gnu.org>
* make.texinfo: Updates for next revision. New date/rev/etc.
Recreate all Info menus. Change license on the manual to the GNU
Free Documentation License. A number of typos.
(Variables Simplify): Don't use "-" before it's defined.
(Automatic Prerequisites): Rewrite the target example to work
properly if the compile fails. Remove incorrect comments about
how "set -e" behaves.
(Text Functions): Move the "word", "wordlist", "words", and
"firstword" functions here, from "File Name Functions".
* make-stds.texi: Update from latest GNU version.
* fdl.texi: (created) Import the latest GNU version.
2002-06-06 Paul D. Smith <psmith@gnu.org>
* variable.c (do_variable_definition): New function: extract the
part of try_variable_definition() that actually sets the value
into a separate function.
(try_variable_definition): Call do_variable_definition() after
parsing the variable definition string.
(define_variable_in_set): Make the name argument const.
* variable.h (enum variable_flavor): Make public.
(do_variable_definition): Create prototype.
* read.c (read_all_makefiles): Create a new built-in variable,
MAKEFILE_LIST.
(read_makefile): Add each makefile read in to this variable value.
2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
* Makefile.DOS.template: Tweak according to changes in the
distribution. Add back the dependencies of *.o files.
* configh.dos.template: Synchronize with config.h.in.
2002-05-09 Paul D. Smith <psmith@gnu.org>
* file.c (file_timestamp_now): Use K&R function declaration.
* getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
#undef it. Remove predefined setup of NLIST_STRUCT. Decide
whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
* configure.in (NLIST_STRUCT): Define this if we have nlist.h and
nlist.n_name is a pointer rather than an array.
* acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
* configure.in: Use it instead of the old version.
* main.c (main): Prefer setvbuf() to setlinebuf().
2002-05-08 Paul D. Smith <psmith@gnu.org>
* Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
(loadavg_LDADD): Ditto.
2002-04-29 Paul D. Smith <psmith@gnu.org>
* expand.c (recursively_expand_for_file): Rename
recursively_expand() to recursively_expand_for_file() and provide
an extra argument, struct file. If the argument is provided, set
the variable scope to that of the file before expanding.
* variable.h (recursively_expand): Make this a macro that invokes
recursively_expand_for_file() with a NULL file pointer.
* variable.c (target_environment): Call the renamed function and
provide the current file context.
Fixes Debian bug #144306.
2002-04-28 Paul D. Smith <psmith@gnu.org>
Allow $(call ...) user-defined variables to be self-referencing
without throwing an error. Allows implementation of transitive
closures, among other possibly useful things.
Requested by: Philip Guenther <guenther@sendmail.com>
* variable.h (struct variable): Add a new field: exp_count, and
new macros to hold its size and maximum value.
(warn_undefined): Make this a macro.
* variable.c (define_variable_in_set): Initialize it.
* expand.c (recursively_expand): If we detect recursive expansion
of a variable, check the exp_count field. If it's greater than 0
allow the recursion and decrement the count.
(warn_undefined): Remove this (now a macro in variable.h).
* function.c (func_call): Before we expand the user-defined
function, modify its exp_count field to contain the maximum
number of recursive calls we'll allow. After the call, reset it
to 0.
2002-04-21 Paul D. Smith <psmith@gnu.org>
Modified to use latest autoconf (2.53), automake (1.6.1), and
gettext (0.11.1). We're using gettext's new "external" support,
to avoid including libintl source with GNU make.
* README.cvs: New file. Explain how to build GNU make from CVS.
* configure.in: Modify checking for the system glob library.
Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
GLOBDIR (we will always put "glob" in SUBDIRS, so automake
etc. will manage it correctly). Set an automake conditional
USE_LOCAL_GLOB to decide whether to compile the glob library.
* getloadavg.c (main): Include make.h in the "TEST" program to
avoid warnings.
* Makefile.am: Remove special rules for loadavg. Replace them
with Automake capabilities for building extra programs.
* signame.c: This file does nothing if the system provide
strsignal(). If not, it implements strsignal(). If the system
doesn't define sys_siglist, then we make our own; otherwise we use
the system version.
* signame.h: Removed.
* main.c (main): No need to invoke signame_init(). Update copyright.
* ABOUT-NLS: Removed.
* gettext.c: Removed.
* gettext.h: Get a simplified copy from the gettext package.
* po/*: Created.
* i18n/*.po: Moved to po/.
* i18n/: Removed.
* config/*: Created. Contains package configuration helper files.
* config.guess, config.sub: Moved to config directory.
* configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
Rework to use new-style autoconf features. Use the "external"
mode for gettext. Make the build.sh config file conditional on
whether build.sh.in exists, to avoid autoconf errors.
* acinclude.m4: Removed almost all macros as being obsolete.
Rewrote remaining macros to use AC_DEFINE.
* acconfig.h: Removed.
* Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
conditional to handle customs support. Remove special handling
for i18n features.
2002-04-20 Paul D. Smith <psmith@gnu.org>
* function.c (func_call): Don't mark the argument variables $1,
etc. as recursive. They've already been fully expanded so
there's no need to do it again, and doing so strips escaped $'s.
Reported by Sebastian Glita <glseba@yahoo.com>.
* remake.c (notice_finished_file): Walk through double-colon
entries via the prev field, not the next field!
Reported by Greg McGary <greg@mcgary.org>.
* main.c (main): If the user specifies -q and asks for a specific
target which is a makefile, we got an assert. In that case it
turns out we should continue normally instead.
* i18n/de.po, i18n/fr.po: Installed an updated translation.
* i18n/he.po: Installed a new translation.
2002-01-07 Paul D. Smith <psmith@gnu.org>
* i18n/es.po, i18n/ru.po: Installed an updated translation.
2001-12-04 Paul D. Smith <psmith@gnu.org>
* i18n/ja.po: Installed an updated translation.
2001-09-06 Paul Eggert <eggert@twinsun.com>
* configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
(AC_CHECK_FUNCS): Add getrlimit, setrlimit.
* main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
are available.
(main): Get rid of any avoidable limit on stack size.
2001-09-04 Paul D. Smith <psmith@gnu.org>
* i18n/da.po: Installed an updated translation.
2001-08-03 Paul D. Smith <psmith@gnu.org>
* i18n/fr.po: Installed an updated translation.
Resolves Debian bug #106720.
2001-06-13 Paul D. Smith <psmith@gnu.org>
* i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
translation.
2001-06-11 Paul D. Smith <psmith@gnu.org>
* i18n/ko.po: Installed a new translation.
2001-05-06 Paul D. Smith <psmith@gnu.org>
Modify the EINTR handling.
* job.c (new_job): Reorganize the jobserver algorithm. Reorder
the way in which we manage the file descriptor/signal handler race
trap to be more efficient.
2001-05-06 Paul Eggert <eggert@twinsun.com>
Restart almost all system calls that are interrupted, instead
of worrying about EINTR. The lone exception is the read() for
job tokens.
* configure.in (HAVE_SA_RESTART): New macro.
(MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
* main.c (main): Use SA_RESTART instead of the old,
nonstandard SA_INTERRUPT.
* configure.in (AC_CHECK_FUNCS): Add bsd_signal.
* main.c (bsd_signal): New function or macro,
if the implementation doesn't supply it.
(The bsd_signal function will be in POSIX 1003.1-200x.)
(HANDLESIG): Remove.
(main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
* make.h (EINTR_SET): Remove.
(SA_RESTART): New macro.
* arscan.c (ar_member_touch): Don't worry about EINTR.
* function.c (func_shell): Likewise.
* job.c (reap_children, free_child, new_job): Likewise.
* main.c (main): Likewise.
* remake.c (touch_file, name_mtime): Likewise.
* arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
if fstat failed with errno!=EINTR, the error was ignored.
* job.c (set_child_handler_action_flags): New function.
(new_job): Use it to temporarily clear the SIGCHLD action flags
while reading the token.
2001-05-02 Paul D. Smith <psmith@gnu.org>
* job.c (start_job_command): Don't add define/endef per-line flags
to the top-level flags setting.
2001-04-03 Paul D. Smith <psmith@gnu.org>
* arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
bit on error, so check for odd return values, not non-0 return
values.
(VMS_get_member_info): Calculate the timezone differences correctly.
Reported by John Fowler <jfowler@nyx.net>.
2001-03-14 Paul D. Smith <psmith@gnu.org>
* variable.c (lookup_variable) [VMS]: Null-terminate the variable
value before invoking define_variable().
Reported by John Fowler <jfowler@nyx.net>.
2001-02-07 Paul D. Smith <psmith@gnu.org>
* read.c (record_target_var): If we reset the variable due to a
command-line variable setting overriding it, turn off the "append"
flag.
2001-01-17 Paul D. Smith <psmith@gnu.org>
* variable.c (lookup_variable) [VMS]: When getting values from the
environment, allocate enough space for the _value_ plus escapes,
not enough space for the name plus escapes :-/.
Reported by John Fowler <jfowler@nyx.net>.
* remake.c (f_mtime): Removed the "***" prefix from the mod time
warnings that make generates, so it doesn't look like an error.
Reported by Karl Berry <karl@gnu.org>.
Fix for PR/2020: Rework appended target-specific variables. I'm
fairly confident this algorithm is finally correct.
* expand.c (allocated_variable_append): Rewrite. Instead of
expanding each appended variable then adding all the expanded
strings together, we append all the unexpanded values going up
through the variable set contexts, then expand the final result.
This behaves just like non-target-specific appended variable
values, while the old way didn't in various corner cases.
(variable_append): New function: recursively append the unexpanded
value of a variable, walking from the outermost variable scope to
the innermost.
* variable.c (lookup_variable): Remove the code that looked up the
variable set list if the found variable was "append". We don't
need this anymore.
(lookup_variable_in_set): Make this non-static so we can use it
elsewhere.
(try_variable_definition): Use lookup_variable_in_set() rather
than faking out current_variable_set_list by hand (cleanup).
* variable.h: Add a prototype for the now non-static
lookup_variable_in_set().
2000-11-17 Paul D. Smith <psmith@gnu.org>
* remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
WINDOWS32 port to assume timestamps can be up to 3 seconds away
before throwing a fit.
2000-11-17 Paul D. Smith <psmith@gnu.org>
* read.c (readline): CRLF calculations had a hole, if you hit the
buffer grow scenario just right. Reworked the algorithm to avoid
the need for len or lastlen at all. Problem description with
sample code chages provided by Chris Faylor <cgf@redhat.com>.

* gettext.c (SWAP): Declare this with the prototype, otherwise
some systems don't work (non-32-bit? Reported for Cray T3E).
Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
2000-10-05 Paul D. Smith <psmith@gnu.org>
* acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
AM_LC_MESSAGES; it doesn't seem to do anything anyway??
* i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
2000-09-22 Paul D. Smith <psmith@gnu.org>
* gettext.c: Don't #define _GETTEXT_H here; we only include some
parts of the real gettext.h here, and we expect to really include
the real gettext.h later. If we keep this #define, it's ignored.
2000-09-21 Paul D. Smith <psmith@gnu.org>
* main.c (log_working_directory): Rework the text to use complete
sentences, to make life simpler for the translators.
2000-08-29 Paul D. Smith <psmith@gnu.org>
* file.c (remove_intermediates): Print a debug message before we
remove intermediate files, so the user (if she uses -d) knows
what's going on.
2000-08-21 Paul D. Smith <psmith@gnu.org>
* variable.c (try_variable_definition): Change how we handle
target-specific append variable defns: instead of just setting the
value, expand it as an append _but_ only within the current
target's context. Otherwise we lose all but the last value if the
variable is appended more than once within the current target
context. Fixes PR/1831.
2000-08-16 Paul D. Smith <psmith@gnu.org>
* function.c (func_shell): Nul-terminate the buffer before
printing an exec error message (just in case it's not!).
Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
2000-07-25 Paul D. Smith <psmith@gnu.org>
* job.c (construct_command_argv_internal): Add "~" to the list of
sh_chars[] which disallow optimizing out the shell call.
2000-07-23 Paul Eggert <eggert@twinsun.com>
* NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
supersedes --disable-nsec-timestamps.
* make.texinfo: Consistently use "time stamp" instead of "timestamp".
* README: Remove --disable-nsec-timestamps.
* filedef.h (struct file.low_resolution_time): New member.
* file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
* remake.c (update_file_1):
Avoid spurious rebuilds due to low resolution time stamps,
generalizing the earlier code that applied only to archive members.
(f_mtime): Archive members always have low resolution time stamps.
* configure.in: Remove --disable-nsec-timestamps, as this has
been superseded by .LOW_RESOLUTION_TIME.
2000-07-23 Paul Eggert <eggert@twinsun.com>
* configure.in (enable_nsec_timestamps): Renamed from
make_cv_nsec_timestamps, since enable/disable options
shouldn't be cached.
2000-07-23 Bruno Haible <haible@clisp.cons.org>
and Paul Eggert <eggert@twinsun.com>
* file.c (file_timestamp_now):
Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
so that clock_gettime is not linked unless needed.
* filedef.h (FILE_TIMESTAMP_HI_RES):
Remove definition; "configure" now does this.
* configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
to before high resolution file timestamp check,
since that check now uses uintmax_t.
(FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
high resolution file timestamps.
(HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
so that we don't link in clock_gettime unnecessarily.
2000-07-17 Paul D. Smith <psmith@gnu.org>
* i18n/ja.po: New version of the translation file.
2000-07-07 Paul D. Smith <psmith@gnu.org>
* remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
the offset calculation.
(name_mtime): Replace EINTR test with EINTR_SET macro.
2000-07-07 Paul Eggert <eggert@twinsun.com>
Fix for PR/1811:
* remake.c (update_file_1):
Avoid spurious rebuilds of archive members due to their
timestamp resolution being only one second.
(f_mtime): Avoid spurious warnings of timestamps in the future due to
the clock's resolution being lower than file timestamps'.
When warning about future timestamps, report only the discrepancy,
not the absolute value of the timestamp and the current time.
* file.c (file_timestamp_now): New arg RESOLUTION.
* filedef.h (file_timestamp_now): Likewise.
(FILE_TIMESTAMP_NS): Now returns int. All uses changed.
2000-07-05 Paul D. Smith <psmith@gnu.org>
* variable.c (lookup_variable) [VMS]: Remove vestigial references
to listp. Fixes PR/1793.
2000-06-26 Paul Eggert <eggert@twinsun.com>
* Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
* dir.c (vms_hash): Ensure ctype macro args are nonnegative.
* remake.c (f_mtime): Remove unused var memtime.
2000-06-25 Martin Buchholz <martin@xemacs.org>
* make.texinfo, NEWS, TODO.private: Minor spelling corrections.
Ran spell-check on make.texinfo.
2000-06-23 Paul D. Smith <psmith@gnu.org>
* main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
* make.h: Define these macros.
* Version 3.79.1 released.
* configure.in: Add a new option, --disable-nsec-timestamps, to
avoid using sub-second timestamps on systems that support it. It
can lead to problems, e.g. if your makefile relies on "cp -p".
* README.template: Document the issue with "cp -p".
* config.guess, config.sub: Updated.
