We want to know if getloadavg() is declared, not if we have it.
* configure.ac: Add it as a define (why is this not the default?)
* src/job.c: Conditionalize declaration on HAVE_DECL_GETLOADAVG.
* config.ami.template: Rename HAVE_GETLOADAVG to HAVE_DECL_GETLOADAVG.
* config.h-vms.template: Ditto.
* config.h.W32.template: Ditto.
Clean up and add new elements from latest config.h.
The gl subdirectory contains our local versions of gnulib module
implementations, so move m4/acinclude.m4 and m4/dospaths.m4 there.
* gl/modules/make-macros: Create a new module to handle the macros.
* bootstrap.conf: Add the new module.
* configure.ac: Macro invocation is moved to make-macros.
* m4/.gitignore: Delete unnecessary ignore file: m4 is empty.
* .gitignore: Add m4/ as an ignored directory.
The gl subdirectory contains our local versions of gnulib module
implementations, so move fnmatch* and glob* from lib to gl/lib.
* gl/modules/make-glob: Add a proper Files: section.
* lib/.gitignore: Delete unnecessary ignore file: lib is empty.
* .gitignore: Add lib/ as an ignored directory.
This macro is obsolete: no useful system has this problem anymore.
* src/output.c (output_init): Remove reference to SETVBUF_REVERSED.
* src/config.ami.template: Remove undef of SETVBUF_REVERSED.
* src/config.h-vms.template: Ditto.
* src/config.h.W32.template: Ditto.
This was needed when getloadavg required privileged access; in this
case GNU make needed to be installed as a setgid program. But this
hasn't been supported by gnulib getloadavg() since 2011 and systems
are no longer using it, so remove it.
* src/makeint.h (user_access): Remove unnecessary function.
(make_access): Ditto.
(child_access): Ditto.
* src/misc.c: Remove implementations of the *_access() functions.
* src/main.c (main): Remove unneeded call to user_access().
* src/job.c (load_too_high): Remove calls to {make,user}_access().
(exec_command): Remove call to child_access().
* src/remote-cstms.c: Remove calls to these methods. I suppose it
might be possible this is needed and was piggy-backing on the
privileged setting but since that's been broken for a while I doubt
this is needed. If so we can bring back the implementation into
this source file.
* src/config.h.W32.template: Remove GETLOADAVG_PRIVILEGED undef.
* src/config.h-vms.template: Ditto.
* src/config.ami.template: Ditto.
We can no longer pass our mondo-warnings options to the builds,
as these will impact all the code including gnulib code, and this
won't work. Also allow the caller to disable either the build.sh
or makefile invocation, for testing.
* Makefile.am: Allow the caller to reset the path to the make
binary to be tested. Remove c90 test: gnulib doesn't support it.
This pulls in entirely too much stuff we don't need. Instead grab
just the gnulib source file, then include it in src/misc.c.
* bootstrap.conf: Add just the lib/strtol.c source file.
* configure.ac: Check for strtoll.
* src/misc.c: Include strtol.c, with QUAD set, if needed.
This pulls in a metric ton of stuff that we otherwise don't need, just
for a one-liner that we already have a replacement for in src/misc.c.
* bootstrap.conf: Remove mempcpy
* configure.ac: Add mempcpy to AC_CHECK_FUNCS
We can assume that the return type of a signal handler is void.
We can assume that, if sys/time.h exists, it can be included
with time.h.
* bootstrap: Get the latest version
* configure.ac: Require a newer version of autoconf.
Remove unnecessary AC_PROG_CC_C99 (already have AC_PROC_CC).
Remove unnecessary AC_AIX, AC_ISC_POSIX, AC_MINIX.
Remove unnecessary AC_HEADER_STDC, AC_HEADER_TIME, AC_TYPE_SIGNAL.
Use strerror to search for the cposix library.
* src/commands.c (fatal_error_signal): Assume return type is void.
* src/commands.h: Ditto.
* src/job.c: Ditto.
* src/job.h: Ditto.
* src/main.c: Ditto.
* src/makeint.h: Ditto.
Don't bother with TIME_WITH_SYS_TIME.
* src/remote-cstms.c: Check HAVE_SYS_TIME_H.
* src/config.ami.template: Remove RETSIGTYPE.
* src/config.h-vms.template: Ditto.
* src/config.h.W32.template: Ditto.
Remove TIME_WITH_SYS_TIME.
Export all variables, including exported makefile variables, when
invoking a shell for the $(shell ...) function. If we detect a
recursive variable expansion, silently ignore that variable and do
not export it. We do print a debug message.
* NEWS: Announce the potential backward-incompatibility.
* doc/make.texi (Shell Function): Document the export behavior.
* src/main.c (main): Add "shell-export" to .FEATURES.
* src/job.h: New function to free struct childbase.
* src/job.c (free_childbase): Implement it; call from free_child.
* src/function.c (func_shell_base): Use target_environment() to
obtain the proper environment for the shell function.
Use free_childbase() to free memory.
(windows32_openpipe): Don't reset the environment: the caller
already provided a proper PATH variable in envp.
* src/variable.c (target_environment): If we detect a recursive
expansion and we're called from func_shell, ignore the variable.
(sync_Path_environment): Simplify and reduce memory allocation.
* tests/scripts/functions/shell: Add tests for this.
* src/file.c (rehash_file): Fix warning message.
(rehash_file): Fix comment to match the behavior.
* tests/scripts/features/se_explicit: Fix test.
* tests/scripts/features/mult_rules: Add a new test.
Commit f2771aa614 introduced a bug where some switches were left out
of MAKEFLAGS. Instead of resetting switches, get the same results by
filtering out duplicates.
* src/makeint.h: Remove reset_switches.
* src/main.c: (reset_switches): Remove reset_switches.
* (main): Remove call to reset_switches.
* (decode_switches): Filter out duplicate flags.
* src/variable.c: (set_special_var): Remove call to reset_switches.
* tests/scripts/variables/MAKEFLAGS: Verify that duplicate flags are
properly filtered out.
If GNUMAKEFLAGS was not present in the environment when we started,
don't add it.
* src/main.c (main): Don't mess with GNUMAKEFLAGS unless it exists.
* tests/scripts/variables/GNUMAKEFLAGS: Test this behavior.
Reported, with initial patch, by Gisle Vanem <gvanem@online.no>
* src/main.c (find_and_set_default_shell) [W32]: Pass search_token
directly to w32ify: no need to make a copy first. When we need to
construct a path, use snprintf() to be sure we don't overwrite
the locally-allocated buffer.
* src/w32/pathstuff.c (w32ify) [W32]: Use the malloc version of
_fullpath(), followed by strncpy(), to avoid overwriting buffers.
Introduce non-deterministic ordering into goal and prerequisite
traversal to help tease out inconsistent failures that may happen
when running in parallel build mode.
Introduce second order into each dependency chain:
1. Existing order is syntactic order reachable via 'dep->next'
2. New order is shuffled order stored as 'dep->shuf' in each 'dep'
When updating goals and prerequisites and '--shuffle' is provided,
use the shuffled order to walk the graph. When automatic variable
are set always use the syntactic order of parameters.
* Makefile.am: Add new src/shuffle.c and src/shuffle.h file.
* build_w32.bat: Ditto.
* builddos.bat: Ditto.
* makefile.com: Ditto.
* po/POTFILES.in: Ditto.
* doc/make.texi: Add documentation for --shuffle.
* doc/make.1: Ditto.
* src/dep.h (DEP): Add the shuf pointer.
* src/filedef.h (struct file): Add was_shuffled flag.
* src/main.c: (shuffle_mode): Global flag for the shuffle mode.
(usage): Add the --shuffle option.
(switches): Ditto.
(main): Set shuffle_mode based on the command line parameter.
Reshuffle prerequisites if requested.
* src/remake.c (update_goal_chain): Walk the shuffled list if enabled.
(update_file_1): Ditto.
* src/shuffle.h: Provide an interface for shuffling prerequisites.
* src/shuffle.c: Implement option parsing and prerequisite shuffling.
* tests/scripts/options/shuffle: Test shuffle option and modes.
* src/makeint.h: Declare it.
* src/arscan.c (ar_scan): Replace atoi() calls with make_toui().
Modify some integral types to be more correct.
* src/job.c (load_too_high): Replace atoi() calls with make_toui().
* src/main.c (main): Ditto.
(decode_switches): Ditto.
memcmp() is always faster than strcmp(). In places where we already
know that both buffers have sufficient size, replace strcmp() with
memcmp().
* src/main.c (main): Replace strncmp() with memcmp()==0.
* src/read.c (word1eq): Ditto.
* src/commands.c (set_file_variables): Ditto.
* src/function.c (func_filter_filterout): Ditto.
(a_word_hash_cmp): Use STRING_N_COMPARE since we know the length.
(func_sort): Replace strcmp() with memcmp().
The standard requires that tolower() returns its argument if there's
no valid lowercase conversion: it's not necessary to check isupper()
before invoking tolower().
Comparing the performance of the old ISTRING_HASH to the new one
on all the files present in GLIBC.

* src/hash.h (ISTRING_HASH_1): Omit isupper() check.
(ISTRING_HASH_2): Ditto.
During second expansion of pattern rules only the first pattern in
each "group" was being substituted. E.g. in this makefile:
.SECONDEXPANSION:
all: hello.x
%.x: $$(wordlist 1, 99, %.1 %.%.2) ; $(info $@ from $^)
hello.1 hello.\%.2 \%.1 \%.\%.2: ;
the output would build "hello.1" and "%.%.2" because each function
is considered a single "word" and only the first pattern is replaced.
Fix the expansion so each whitespace-separated string is considered a
word and the first pattern is replaced, giving "hello.1" and
"hello.%.2".
* src/rule.c (snap_implicit_rules): Keep enough space to replace %
with $(*F) if necessary.
* src/implicit.c (pattern_search): During second expansion break each
get_next_word result into individual words and replace the first % in
each with $* or $(*F) as needed.
* tests/scripts/features/patternrules: Add tests for variations.
The hash function we use can yield different results on big- and
little-endian systems which makes test output different. Choose
names to avoid this.
* tests/scripts/features/patternrules: Choose portable target names.
* tests/scripts/features/se_explicit: Ditto.
* tests/scripts/features/se_implicit: Ditto.
If -R is given on the command line it implies -r as well; make this
same assumption if -R is provided in MAKEFLAGS set in the makefile.
* src/main.c (main): Check no_builtin_variables_flag after reading
makefiles.
* tests/scripts/options/dash-r: Add a test.
Previously we always used the file->stem value as our stem in
set_file_variables(); when that wasn't correct we had to temporarily
set that value while the function was called, then reset it afterward.
This led to issues (for example when we assumed the stem was a cached
string but it wasn't).
Avoid this by passing in the stem as an argument so that different
values can be provided.
Add tests to verify this.
* src/commands.c (set_file_variables): Take second parameter stem to
relieve the callers of set_file_variables() from setting/restoring
file->stem.
* src/commands.h (set_file_variables): Ditto.
(execute_file_commands): Pass file->stem to set_file_variables().
* src/file.c (expand_deps): Pass d->stem to set_file_variables() and
remove set and restore of file->stem.
* src/implicit.c (pattern_search): Pass stem to set_file_variables()
and remove set and restore of file->stem.
* tests/scripts/features/se_explicit: Add new tests.
* tests/scripts/features/se_implicit: Ditto.
* tests/scripts/features/se_statpat: Ditto.
* tests/scripts/variables/automatic: Ditto.
During normal pattern rule expansion only the first pattern (%) is
expanded; however during secondary expansion all patterns were
expanded. Modify secondary expansion to match the behavior of normal
expansion.
Implementation tweaked by Paul Smith <psmith@gnu.org>
* src/file.c (expand_deps): Don't use subst_expand() which replaces
all % with $*: instead replace only the first one, by hand.
Fix a memory leak where the dep structure was not always freed.
* tests/scripts/features/statipattrules: Use .RECIPEPREFIX not TAB.
Add a series of tests verifying that static pattern rules with and
without secondary expansion both return the same results.
Original patch from Dmitry Goncharov <dgoncharov@users.sf.net>
Fix the ar flags to match the default values in make. If the
U option is supported, add it to the end not the beginning,
since ARFLAGS now starts with a "-".
* tests/test_driver.pl: Add defaults for global variables.
(get_osname): Preserve $osname if it's set from $^O
* tests/scripts/features/archive: Set the default arflags.
If "U" is available add it to the end of the flags.
