[SV 40657] Reinstate old behavior for suffix rules with prereqs
POSIX says that suffix rules cannot have prerequisites, but after
making this change we observed a number of makefiles "in the wild"
that were relying on this behavior and failed.
For .POSIX: makefiles, obey POSIX. Otherwise preserve the old
behavior. However, generate a warning so users know this is a
problem. In a future version we will change all behavior to be
POSIX-conforming.
* NEWS: describe the change
* src/rule.c (convert_to_pattern): If posix_pedantic don't make a
pattern rule if prereqs exist. Otherwise show a warning.
* tests/scripts/features/suffixrules: Add tests for the new behavior
including .POSIX vs. non-.POSIX.
2020-01-05 Dmitry Goncharov <dgoncharov@users.sf.net>
* tests/test_driver.pl: Enhance error messages
2020-01-04 Paul Smith <psmith@gnu.org>
* doc/make.texi: Change the GFDL to an Appendix
* NEWS: Clarify authorship of new features.
Enable compilation with C90 compilers
* configure.ac: Try compiling Guile headers: they don't work with C90.
* maintMakefile: Simplify config checks via target-specific variables.
* src/makeint.h: Use ATTRIBUTE rather than defining __attribute__,
as that causes compile issues with system headers.
(ENUM_BITFIELD): Don't use enum bitfields in ANSI mode.
* src/main.c: Use ATTRIBUTE instead of __attribute__.
* src/job.h: Ditto.
* src/file.c: Don't define variables inside for loops.
* src/rule.c: Ditto.
* src/dep.h (SI): Only use static inline in non-ANSI mode.
2020-01-03 Paul Smith <psmith@gnu.org>

Support the .EXTRA_PREREQS special variable
Initial implementation by Christof Warlich <cwarlich@gmx.de>
* NEWS: Announce the new feature.
* doc/make.texi (Other Special Variables): Document .EXTRA_PREREQS.
* src/dep.h (struct dep): New flag to note extra prereq deps.
* src/filedef.h (expand_extra_prereqs): Declare a function to expand
the value of .EXTRA_PREREQS.
* src/file.c (expand_extra_prereqs): Given a struct variable lookup
of .EXTRA_PREREQS, convert it into a list of deps and for each one
make sure it has a struct file and has the new flag set.
(snap_file): A new function invoked by hash_map that will perform
per-file operations: set up second expansion, intermediate, and also
.EXTRA_PREREQS. Manage circular dependencies by ignoring them.
(snap_deps): Defer per-file operations until the end. Look up the
global .EXTRA_PREREQS and pass it along to snap_file for each file.
* src/implicit.c (struct patdeps): Remember the extra prereqs flag.
(pattern_search): Transfer extra prereqs flag settings into the
matched pattern rule.
* src/rule.h (snap_implicit_rules): Rename count_implicit_rules to
snap_implicit_rules since we now do more than count.
* src/rule.c (snap_implicit_rules): As we walk through all the pattern
rules, add in any global .EXTRA_PREREQS to the dep list. Ensure we
take them into account for the max number of prereqs and name length.
* src/main.c (main): Add extra-prereqs to .FEATURES.
Call the renamed snap_implicit_rules.
* tests/scripts/variables/EXTRA_PREREQS: Add tests.
2020-01-03 Paul Smith <psmith@gnu.org>
* tests/scripts/features/patternrules: Use Windows-compatible quoting

2019-12-27 Paul Smith <psmith@gnu.org>
* NEWS: Remove info about disabled /proc/loadavg usage.
2019-12-27 Paul Smith <psmith@gnu.org>
[SV 57022] Avoid posix_spawn which fails asynchronously
Avoid using posix_spawn implementations that fail asynchronously when
the spawned program can't be invoked: this means instead of getting
an error such as "No such file or directory" we get just "Exit 127".
Original implementation of the configure.ac macro provided by
Martin Dorey <martin.dorey@hds.com>
Original implementation of the regression tests provided by
Dmitry Goncharov <dgoncharov@users.sf.net>
* configure.ac: Test whether posix_spawn fails asynchronously. In a
cross-compilation environment, assume that it does not. If we detect
that it does, fall back to fork/exec.
* tests/scripts/features/exec: Add regression tests for different
shebang invocation methods.
2019-12-26 Paul Smith <psmith@gnu.org>
[SV 56655] Allow pattern expansion to contain spaces
* src/dep.h: Add a new flag PARSEFS_ONEWORD
* src/read.c (parse_file_seq): If PARSEFS_ONEWORD is given, treat the
entire incoming string as a single pattern.
* src/implicit.c (pattern_search): Pass PARSEFS_ONEWORD when parsing
patterns for wildcards.
* tests/scripts/features/patternrules: Add a new test.
2019-12-18 Ben Wijen <ben@wijen.net>
* src/misc.c (spin): On WINDOWS32 use Sleep() instead of sleep()
* bootstrap.bat: Fix typo in batch file name
2019-12-18 Paul Smith <psmith@gnu.org>
* src/config.h.W32.template: [SV 57152] MinGW32 doesn't support d_type
2019-12-18 Jouke Witteveen <j.witteveen@gmail.com>
[SV 54161] Fix second expansion of $* for paths
If the stem matches a path containing a directory not just a
filename, make sure the second expansion of $* in the
prerequisites matches $* in the recipe. This requires using
$(*F) when replacing % in the first expansion to preserve the
simple filename.
* src/implicit.c (pattern_search): If lastslash is set prepend
the directory onto the stem. Then use $(*F) when expanding %.
* tests/scripts/features/se_implicit: Add a test case
2019-12-17 Jouke Witteveen <j.witteveen@gmail.com>
* src/implicit.c (pattern_search): Set lastslash correctly
If filename contained multiple slashes lastslash is wrongly set to 0.
* configure.ac: Check for the GNU memrchr() extension function.
* src/misc.c (memrchr): Supply memrchr() if not available.
* src/implicit.c (pattern-search): Remove unneeded 'dir' variable
2019-12-17 Paul Smith <psmith@gnu.org>
* Makefile.am: Build lzip package instead of bzip2
* README.git: Mention changed requirements.
* src/job.c (load_too_high): Disable Linux /proc/loadavg for now
This new feature has a problem: if you provide a load which is
larger than the number of cores then it will always run every job.
Before we can enable it we need to at the least learn how to clamp
this value to the number of cores. To experiment with it, set
PROC_FD_INIT to -2 in job.c to re-enable the feature.
* tests/run_make_tests.pl (set_more_defaults): Fix typo
2019-12-16 Paul Smith <psmith@gnu.org>
* tests/run_make_tests.pl (subst_make_string): Force use of /
On Windows the path to the helper tool will contain '\': this will
fail if recipes are run with a POSIX shell. Convert '\' to '/'
on Windows. While here, escape any spaces in the path as well.
Rename jhelp.pl to thelp.pl and make it a generic test helper.
* tests/thelp.pl: Rename from tests/jhelp.pl.
(op): Use names instead of options for the operations.
(op): Add new operations for sleep, mkdir, and rm.
(op): Enhance wait to time out
* tests/run_make_tests.pl: Add a new #HELPER# replacement
(subst_make_string): Use fully-qualified path to thelp.pl
* tests/scripts/features/parallelism: Update to use thelp.pl
and the new named operations. Use thelp.pl sleep instead of
system-specific sleep commands.
* tests/scripts/features/output-sync: Update to use thelp.pl
instead of complex shell scripts.
* Makefile.am: Distribute tests/thelp.pl instead of tests/jhelp.pl
2019-10-10 Paul Eggert <eggert@cs.ucla.edu>
Port functions/shell test to Solaris 10
* tests/scripts/functions/shell: Port exit-status calculation

2019-09-22 Paul Smith <psmith@gnu.org>
* tests/scripts/features/vpathplus: Fix output for big-endian systems.
Our hashing algorithm gives different ordering on LE vs BE systems.
Patch from Dmitry Goncharov <dgoncharov@users.sf.net>.
2019-09-22 Florian Weimer <fweimer@redhat.com> (tiny change)
* configure.ac (HAVE_GETTIMEOFDAY): Avoid undeclared exit function.
2019-09-22 Paul Smith <psmith@gnu.org>
* test/test_driver.el (_run_with_timeout): Show error message.
* job.c (child_error): Modify error message string.
This reverts commit 6264deece3bb77798240a906ceed79097adbcf48.
Further investigation discovers that the real issue is that
GNU Emacs compile mode doesn't have a matching regex for GNU
make error messages generated when targets fail. I submitted
a patch to GNU Emacs adding a matcher for compile mode.
2019-09-21 Paul Smith <psmith@gnu.org>
* tests: Convert from File::Spec::Functions to File::Spec.
Users report the Functions version doesn't work correctly for some
older versions of Perl.
* tests/scripts/function/guile: Valgrind doesn't work with Guile.
* src/job.c (child_execute_job): Allocate space for argv NULL.
2019-09-21 Paul Smith <psmith@gnu.org>
[SV 56918] Compute job slots properly on failing command
Ensure we properly reduce job_slots_used if a command fails because
it doesn't exist/can't be started.
* src/job.h (struct child): Add a field jobslot to be set when using
a job slot.
* src/job.c (start_waiting_job): Remember if we are using a job slot.
(reap_children): Reduce number of job slots used by jobslot.
2019-09-21 Paul Smith <psmith@gnu.org>
* src/arscan.c (ar_scan): Restrict length for sscanf of ar_mode.

* tests/run_make_test.pl: Fix support for valgrind.
Change the variable holding the make command to be a list that can
hold extra commands and options, not just a string.
* tests/run_make_tests.pl (find_prog): Fix syntax error.
2019-09-16 Paul Smith <psmith@gnu.org>
* NEWS: Update date and clarify -l change.
* tests/run_make_tests.pl: Create $scriptsuffix for Windows/VMS.
* tests/scripts/features/targetvars: Add a suffix to scripts.
* tests/scripts/misc/general4: Ditto.
2019-09-16 Paul Smith <psmith@gnu.org>
Refresh the test suite framework implementation.
Go through both run_make_tests.pl and test_driver.pl and slightly
modernize the Perl and clean up indentation etc. Fix a number of
warnings in the test scripts detected by running with -w.
* tests/test_driver.pl: Move make error string detection out of the
base test driver.
(run_all_tests): Ensure that we always look for tests in the cwd.
* tests/run_make_tests.pl: Use File::Spec for path manipulations.
Correctly use setlocale() when detecting error strings.
Get configuration from the config-flags.pm file not config.status.
* tests/scripts/features/archives: Use new $cwddir variable.
* tests/scripts/features/reinvoke: Add missing semicolon.

2019-09-16 Paul Smith <psmith@gnu.org>
* tests/config-flags.pm.in: Add USE_SYSTEM_GLOB.
* tests/config_flags_pm.com [VMS]: Ditto.

2019-09-10 Eli Zaretskii <eliz@gnu.org>
Revert "[SV 56449] (Windows) Use slow path if '%' appears in the command"
This reverts commit 38e96eadea6e2cd42a0f414959bac327de9f468a.
Per discussion on Savannah, the modified behavior matches
the way % is handled in batch files, but not in cmd command
lines. And since Make mostly tries to emulate the command
line, the new behavior is unexpected and backward-incompatible.
2019-09-09 Paul Smith <psmith@gnu.org>
Rework the creation of build.sh so it's not a template.
* build.sh: Rename from build.template. Get the list of objects
from the Makefile. Move configure-replaced variables ...
* build.cfg.in: to this new .in file.
* configure.ac: Remove special handling of build.sh.in and add
build.cfg as a generated file.
* Makefile.am (EXTRA_DIST): Remove build.sh.in and add build.sh
and build.cfg.in for build.sh.in.
* maintMakefile: Remove handling for build.template. Treat
build.sh as a source file, not a generated file.
* .gitignore: Ignore generated build.cfg file.
2019-09-08 Paul Smith <psmith@gnu.org>
* gl/modules/make-glob: Move local glob configure.ac to here
* configure.ac: from here.
2019-09-08 Paul Smith <psmith@gnu.org>
[SV 56834] Support local PATH search with posix_spawnp
When using exec we install the child's environment before invoking
execlp(), so commands are found on the child's PATH. posix_spawnp
searches on the parent's PATH, which we don't want.
Import gnulib's findprog-in module and use it to search the child's
PATH, then use posix_spawn() to run it.
Also, posix_spawn() does not fall back to trying sh on ENOEXEC, as
execlp() does, so implement that as well.
* bootstrap.conf: Add the findprog-in gnulib module
* src/job.c: Include findprog.h if we're using posix_spawn.
(start_job_command): Remove the handling of child->cmd_name,
(child_execute_job): and add it here. Look up the command to be
run in the child's path and invoke it if found. If it fails with
ENOEXEC then retry it as an argument to the default shell.
* tests/scripts/misc/general4: Test makefile PATH assignments.
* tests/scripts/features/targetvars: Ditto, for target variables.
2019-09-07 Paul Smith <psmith@gnu.org>
* doc/make.texi (Recipe Execution): Correct example to use $(<[DF])
* configure.ac: Check whether struct dirent has a d_type field
* src/dir.c (dir_contents_file_exists_p): Use the autoconf macro
HAVE_STRUCT_DIRENT_D_TYPE rather than relying on the GNU libc-
specific _DIRENT_HAVE_D_TYPE.
* lib/glob.c: Set HAVE_D_TYPE if HAVE_STRUCT_DIRENT_D_TYPE.
* src/config.h.W32.template [W32]: Add support for dirent.d_type
* src/w32/include/dirent.h: Add DT_* values for dirent.d_type
(struct dirent): Add d_type
* src/w32/compat/durent.c (readdir): Set dirent.d_type based on
Windows file attributes.
* src/makeint.h: Add typedef for mode_t if !HAVE_UMASK
* build.template: Rewrite to allow gnulib support.
* doc/make.texi: Clarify that the jobserver pipe is "blocking"
2019-09-07 Paul Smith <psmith@gnu.org>
Align child_execute_job among different ports
Create a struct childbase which is the basics of struct child needed
to invoke child_execute_job(), and can be cast back and forth to a
struct child. Ensure all implementations of child_execute_job() take
the same arguments.
* src/job.h (CHILDBASE): Create a macro to hold the base parts.
(struct childbase): A structure containing CHILDBASE.
(struct child): Use CHILDBASE as the initial part of child.
[VMS]: Remove declaration of VMS version of child_execute_job.
* src/job.c (start_job_command): Use new child_execute_job() call.
(child_execute_job) [__EMX__]: Implement new calling signature.
(child_execute_job): Implement new calling signature.
* src/main.c (main) [__EMX__]: Use new child_execute_job() call.
* src/function.c (func_shell_base): Use new child_execute_job() call.
* src/vmsjobs.c (vmsHandleChildTerm): Accept struct childbase.
* src/vmsjobs.c (child_execute_job): Implement new calling signature.
Modify the return value to be pid_t, not a boolean, and return the
PID rather than setting it in the child. This is OK because our only
caller immediately reset PID to -1 anyway if we return 0.
2019-09-07 Paul Smith <psmith@gnu.org>
* doc/make.tex (Substitution Refs): Clarify patsubst relationship.
* src/job.c (start_job_command) [VMS]: Correct VMS comment.
2019-09-07 Paul Smith <psmith@gnu.org>
Show useful errors when posix_spawn() doesn't do so
The posix_spawn() function may not detect that the command to run is
invalid when it's invoked. Instead, it will run then exit with
error code 127. If that happens do our best to present the user
with a useful error message.
* src/job.h (struct child): Add cmd_name to hold the command we ran.
* src/job.c (start_job_command): On success, remember the cmd_name.
(reap_children): On exit 127, stat cmd_name and show a useful error.
(free_child): Free cmd_name.
2019-09-07 Paul Smith <psmith@gnu.org>
* README.git: Describe GCC and GNU make requirements
* maintMakefile: Put custom C flags into a separate variable
so they can be overridden more easily on the command line.
* tests/scripts/features/archives: Fix expected long ar name output.
* tetss/run_make_test.pl: Avoid 'sh -c' for Windows portability.
Update to GNU make release candidate 4.2.91
* tests/scripts/functions/wildcard: Skip dangling symlink test.
The built-in glob implementation does not correctly handle dangling
symlinks. This needs to be fixed by switching to the latest glob
implementation from gnulib but that's a big job: for now avoid the
test if we know it will fail.
* maintMakefile: Use check-local when testing build.sh.
Running 'make check' will rebuild 'make' so we're not testing the
build.sh-generated make binary.
2019-09-07 Paul Smith <psmith@gnu.org>
Don't reset stack size when using posix_spawn()
There's no way to run setrlimit() from posix_spawn() so we can't reset
the stack limit in children; thus, don't change it in the parent.
* src/makeint.h (SET_STACK_SIZE): Don't set this when HAVE_POSIX_SPAWN.
* src/job.c (child_execute_job): Remove useless comment.
2019-09-07 Paul Smith <psmith@gnu.org>
* configure.ac: Remove redundant getloadavg gnulib support
* src/dir.c (dir_setup_glob): Initialize unused gl_offs.
* tests/scripts/functions/wildcard: Add trailing slash tests.

‘"src/main.c", line 2643: warning: assignment type mismatch:
pointer to char "=" pointer to const char’.
Pacify Oracle Studio 12.6
* src/arscan.c [VMS]: Use ‘#if !defined LBR$_HDRTRUNC’ instead
of ‘#ifndef LBR$_HDRTRUNC’ to pacify Oracle Studio 12.6, which
looks inside unused #if branches for preprocessor syntax errors.
Without this patch it complains ‘"src/arscan.c", line 43: warning:
tokens ignored at end of directive line’.

Use forward slashes in calls to :Compile, so that linking with GNU
ld works.
* src/makeint.h [!HAVE_UMASK]: Prototype for 'umask'.
(UMASK, MODE_T): Don't define.
* src/misc.c (get_tmpfile): Don't call UMASK, call umask, to
avoid compilation warning on !HAVE_UMASK platforms.
* src/output.c (output_tmpfd): Likewise.
* src/misc.c (umask) [!HAVE_UMASK]: New no-op function.
* src/config.h.W32.template (__USE_MINGW_ANSI_STDIO)

stdio functions, which also support the non-standard 'Id' and 'Ix'
specifiers.
(HAVE_UMASK) [__MINGW32__]: Define to 1.
* src/arscan.c (ar_member_touch): Type-cast argument of strlen to
avoid compiler warnings.

* NEWS: Update for pre-release
2019-08-26 Paul Smith <psmith@gnu.org>
Update maintainer mode to support debug wait points.
Make a spin() method available when compiled in maintainer mode.
If a file exists in the working directory with a specific name,
make will sleep until the file is deleted.
Ensure that maintainer mode is enabled on Windows, using the same
algorithm we use on POSIX / autoconf systems.
* build_w32.bat: If maintMakefile exists, enable maintainer mode.
* src/main.c (main): Replace Windows-only suspend flag with spin().
* src/makeint.h: A SPIN() macro calls spin() in maintainer mode.
* src/misc.c (spin): If a spin file exists sleep until it's deleted.
2019-08-26 Paul Smith <psmith@gnu.org>

The check for matching a file's command to the default rule's command

[SV 8297] Implement "grouped targets" for explicit rules.
This patch allows "grouped targets" using the &: syntax:
tgt1 tgt2 ... tgtn &: pre1 pre2 ...
recipe
When the &: separator is used (in single or double colon forms), all
the targets are understood to be built by a single invocation of the
recipe. This is accomplished by piggy-backing on the already-existing
pattern rule feature, using the file's "also_make" list.

[SV 54233] Preserve higher command_state values on also_make targets.
If multiple pattern rules have the same pattern as also-make targets

forever for it to finish.

Commit bc9d72beb0cb "Resolve issues discovered by static code

on non-AIX systems it also checked BSD-style long names against the
short name limits and and checked the *offset* for GNU-style long
names against the short name limits. This caused valid long names to
be rejected.

Queue failed fork() (etc.) to be handled like any other failed job.
If we failed to fork() we were essentially exiting make immediately
without respect to ignore flags, etc. On one hand that makes sense
because if you can't fork you're in real trouble, but it doesn't
work so well on systems where we don't fork at all. Instead, treat
a fork error like any other error by delaying the handling until
the next call to reap_children(). Any child with a PID of -1 is
considered to have died before starting so check these first without
waiting for them.

* src/dir.c: Preserve glob d_type field
When using GNU make on a system with glibc glob a pattern ending in
a slash is also matching regular files, but only in subdirectories:
$ mkdir -p dir/subdir
$ cd dir
$ touch file1 subdir/file2
$ echo 'test:; @echo $(wildcard */ */*/)' | make -f -
subdir/ subdir/file2
$ echo 'test: */ */*/; @echo "$?" != */ */*/' | make -f -
subdir/ subdir/file2 != subdir/ */*/
It happens because in the gl->gl_readdir callback supplied to glob(),
dirent->d_type is set to DT_UNKNOWN, and the glob() implementation
in glibc assumes that such a directory entry *cannot* possibly be a
regular file.
Pass the actual d_type down to glob(); this is the right thing to do
even if glibc is fixed, because it saves an extra stat() syscall for
each dirent.

Convert GNU make to use the gnulib portability library
Move content from glob/* and config/* into standard GNU directory
locations lib/* and m4/*.
Install the gnulib bootstrap script and its configuration file, and
create a bootstrap.bat file for Windows. Update the README.git file
with new requirements and instructions for building from Git.
At this point we only install the alloca, getloadavg, and FDL modules
from gnulib. We keep our old glob/fnmatch implementation since the
gnulib versions require significant amounts of infrastructure which
doesn't exist on Windows yet. Further work is required here.
Due to a problem with gnulib's version of getloadavg, we need to bump
the minimum required version of automake to 1.16.1 unfortunately.

Remove unsupported build facilities.
Over time the non-standard build and install systems (nmake files,
smake files, Visual Studio project files, etc.) have atrophied and
maintaining them is not worth the effort, for such a simple utility
as make. Remove all the non-standard build tool support and unify
OS-specific build rules under a basic set of (GNU make) makefiles.
Preserve the existing bootstrapping scripts (for POSIX, Windows,
and MS-DOS). Also the existing VMS build scripts are left unchanged:
I don't have enough experience with VMS to venture into this area.
Perhaps one of the VMS maintainers might like to determine whether
conversion would be appropriate.
Rather than create libraries for w32 and glob (non-POSIX), simply
link the object files directly to remove the complexity.
* NEWS: Update with user-facing notes.

Do not use STOP_SET for singleton compares.
Compare against '$' directly rather than using MAP_VARIABLE.
This saves ~10% for find_map_function, which is the top hotspot in
QEMU's no-op build. The build is sped up overall by about 1.5%
more (from 11.1s to 10.95s).
* read.c (find_map_function): Do not compare against singleton sets.
2017-11-11 Paolo Bonzini <pbonzini@redhat.com>
Speedup parsing of functions.
Use the stopchar map to quickly jump over everything that is
not an open/close brace, an open/close parenthesis or a comma.
This saves 1% on QEMU's noop build (from 11.23s to 11.1s).
* function.c (find_next_argument, handle_function): Check
with STOP_SET before comparing against individual characters.
* main.c (initialize_stopchar_map): Initialize MAP_VARSEP
mappings in stopchar_map.
* makeint.h (MAP_VARSEP): New.
2017-11-11 Paolo Bonzini <pbonzini@redhat.com>

2017-11-11 Paolo Bonzini <pbonzini@redhat.com>
Use Jenkins hash.
This is about twice as fast as the current hash, and removes the
need for double hashing (improving locality of reference). The
hash function is based on Bob Jenkins' design, slightly adapted
wherever Make needs to hash NUL-terminated strings. The old hash
function is kept for case-insensitive hashing.
This saves 8.5% on QEMU's no-op build (from 12.87s to 11.78s).
* configure.ac: Check endianness.
* hash.c (rol32, jhash_mix, jhash_final, JHASH_INITVAL,
sum_get_unaligned_32, jhash): New.
* hash.h (STRING_HASH_1, STRING_N_HASH_1): Use jhash.
(STRING_HASH_2, STRING_N_HASH_2): Return a dummy value.
(STRING_N_COMPARE, return_STRING_N_COMPARE): Prefer memcmp to strncmp.
2017-11-11 Paolo Bonzini <pbonzini@redhat.com>
Use strchr for simple case of find_char_unquote.
In most cases, find_char_unquote has a single stopchar. In that
case we can look for it using strchr's optimized implementation.
This saves 3.5% on QEMU's noop build (from 11.78s to 11.37s).
* read.c (find_char_unquote): Rename to find_map_unquote. Replace
with an implementation optimized for the case where the stopchar
is a singleton. Adjust all callers.
2017-11-11 Paolo Bonzini <pbonzini@redhat.com>
Use strchr/memmove in collapse_continuations.
collapse_continuations is already using strchr to speed up the
common case of no backslash-newline sequence, but on modern
processors it is faster to scan the string twice with
strchr+memmove (or strlen+memmove) than to move bytes manually.
Saves about 1.5% on QEMU's no-op build (from 11.37s to 11.23s).
* misc.c (collapse_continuations): Rewrite the scanning of LINE.

[SV 47995] Ensure forced double-colon rules work with -j.
The fix for SV 44742 had a side-effect that some double-colon targets
were skipped. This happens because the "considered" facility assumed
that all targets would be visited on each walk through the dependency
graph: we used a bit for considered and toggled it on each pass; if
we didn't walk the entire graph on every pass the bit would get out
of sync. The new behavior after SV 44742 might return early without
walking the entire graph. To fix this I changed the considered value
to an integer which is monotonically increasing: it is then never
possible to incorrectly determine that a previous pass through the
graph already considered the current target.
* filedef.h (struct file): make CONSIDERED an unsigned int.
* main.c (main): No longer need to reset CONSIDERED.
* remake.c (update_goal_chain): increment CONSIDERED rather than

Preserve the real value of -jN in MAKEFLAGS using jobserver.
Previously if the jobserver was active, MAKEFLAGS would contain only
the -j option but not the number (not -j5 or whatever) so users

on the command line if the jobserver is already activated.

[SV 45728] Detect changes in .VARIABLES more accurately.
For performance, we only recompute .VARIABLES when (a) it's expanded
and (b) when its value will change from a previous expansion. To
determine (b) we were checking the number of entries in the hash
table which used to work until we started undefining entries: now if
you undefine and redefine the same number of entries in between
expanding .VARIABLES, it doesn't detect any change. Instead, keep
an increasing change number.
* variables.c: Add variable_changenum.
(define_variable_in_set, merge_variable_sets): Increment
variable_changenum if adding a new variable to the global set.
(undefine_variable_in_set): Increment variable_changenum if
undefining a variable from the global set.
(lookup_special_var): Test variable_changenum not the hash table.
* tests/scripts/variables/special: Test undefining variables.
* main.c(main): Disable output sync without parallel builds.
[SV 46581] Pre-define .LOADED to avoid warnings.
* main.c (main): Pre-define .LOADED as a default-level variable.
* load.c (load_file): Set the value rather than append it. Avoid
adding an extra initial whitespace.
* tests/scripts/features/load: Run with --warn-undefined-variables.
2016-03-13 Paul Smith <psmith@gnu.org>
[SV 44555] Use vfork() instead of fork() where available.
Testing has shown that vfork() is actually significantly
more efficient on systems where it's supported, even for
copy-on-write implementations. If make is big enough,
duplicating the page tables is significant overhead.
* configure.ac: Check for fork/vfork.
* makeint.h: Include vfork.h and set up #define for it.
* os.h, posixos.c (get_bad_stdin): For children who can't use
the normal stdin file descriptor, get a broken one.
* job.c (start_job_command): Avoid so many ifdefs and simplify
the invocation of child_execute_job()
(child_execute_job): move the fork operation here so it can
return early for the parent process. Switch to use vfork().
* function.c (func_shell_base): Use new child_execute_job() and
simplify ifdefs.
* job.h, main.c, remote-cstms.c, vmsjobs.c, w32os.c: Update
declarations and calls.
2016-03-09 Paul Smith <psmith@gnu.org>
* job.c (exec_command): [SV 47365] Show error on exec failure.
2016-03-08 Paul Smith <psmith@gnu.org>
[SV 46261] Use pselect() for jobserver where supported.
* Makefile.am, configure.ac: Check for pselect() and sys/select.h.
* main.c (main): Block SIGCHLD if we have pselect() support.
* posixos.c (jobserver_acquire): If we support pselect() then use
it to query the jobserver pipe, while also listening for SIGCHLD.
Also pselect() supports a timeout so avoid alarm() calls.
Clean up some compiler warnings.
* commands.c, commands.h: Use unsigned char for flags.
* dir.c: Use time_t and size_t, and char for a boolean value.
* job.c: Use unsigned and char.
* read.c: Return a signed type since -1 is a valid return code.
Extract jobserver implementation into OS-specific files.
* os.h, posixos.c, w32/w32os.c: New files implementing jobserver.
* job.c, job.h, main.c, makeint.h: Move content to new files.
* w32/include/sub_proc.h, w32/subproc/sub_proc.c: Ditto.
* Makefile.am: Build and package OS-specific files.
* build_w32.bat, make_msvc_net2003.vcproj, README.W32.template:
Update for new files, and clean up the build.
* POTFILES.in, maintMakefile, NMakefile.template: Ditto.
* w32/subproc/build.bat: Delete as unused.
[SV 46261] Add more EINTRLOOP wrappers.
This cannot be a perfect solution because there are always other
possible places EINTR can happen, including external libraries
such as gettext, Guile etc.
2016-02-29 Paul Smith <psmith@gnu.org>
* strcache.c (add_hugestring): [SV 46832] Support huge strings.
The strcache was limited to strings of length 65535 or less,
because the length is kept in an unsigned short. To support
huge strings add a new simple linked list, which we don't try
to hash.
* strcache.c (add_string): [SV 47071] Handle huge initial string.
If the very first string added to the string cache is more than
half the maximum size, we failed when moving the only strcache
buffer to the full list.
[SV 47151] Exit with 1 when checking recursive make -q
* job.h (struct child): New bit to mark recursive command lines.
* job.c (start_job_command): Set the recursive command line bit.
(reap_children): If the child is a recursive command and it exits
with 1 during question mode, don't print an error and exit with 1.
* tests/scripts/options/dash-q: Add a regression test.
* main.c (define_makeflags): Add parens to avoid GCC warning.
2016-02-29 Paul Smith <psmith@gnu.org>
* tests/scripts/features/archives: Handle deterministic archives.
Newer versions of binutils allow ar to be compiled to generate
"deterministic archives" by default: in this mode no timestamp
information is generated in the static archive, which utterly
breaks GNU make's archive updating capability. Debian and Ubuntu
have turned this feature on by default in their distributions
which causes the regression tests to fail.
Update the regression tests to check for the availability of the
"U" option to ar which disables deterministic archives and allows
GNU make's archive support to work properly again.
2016-02-28 Paul Smith <psmith@gnu.org>
Update Copyright statements for the new year.
* doc/make.texi: [SV 47163] Fix typo in 'ifdef' documentation.
* doc/make.texi: [SV 35455] Add more uses for Empty Recipes.
2015-11-07 Gisle Vanem <gvanem@yahoo.no>
Fix diagnostics on MS-Windows when environment is too large
* w32/subproc/sub_proc.c (process_begin): Fix test of the error

2015-10-27 Eli Zaretskii <eliz@gnu.org>
Update README.W32.template
* README.W32.template: Update for latest developments. Make it
clear we don't recommend using HAVE_CASE_INSENSITIVE_FS in
general.
[SV 46304] Don't invoke C++ compiler on C sources on MS-Windows
* default.c (default_variables) [HAVE_CASE_INSENSITIVE_FS]: Make
COMPILE.C and LINK.C be synonyms for COMPILE.c and LINK.c,
respectively.
2015-09-23 Eli Zaretskii <eliz@gnu.org>
[SV 45838] When invoking w32 programs, don't use free'd memory.
* w32/subproc/sub_proc.c (process_begin): Freeing argv[0] makes
the other argv[i] pointers invalid, so need to allocate a new
array and copy argv[i] for i != 0 first, replacing argv[0] with
the batch file name, before we can free argv[0].
2015-07-13 Paul Smith <psmith@gnu.org>
* implicit.c (pattern_search): [SV 43677] Mark files secondary.
In order to fix SV 12267 we were marking the prerequisites of
implicit (pattern) targets that existed elsewhere in the makefile
as precious to keep them from being deleted as intermediate files.
However this also keeps them from being deleted on error. Instead
mark them as secondary.
* tests/scripts/targets/DELETE_ON_ERROR: Test DELETE_ON_ERROR.
2015-07-12 Paul Smith <psmith@gnu.org>
[SV 28092] Preserve the exit status of the $(shell...) function.
Add a new variable .SHELLSTATUS which holds the exit status of the
last-invoked shell function or != assignment.
* NEWS, doc/make.texi: Document the change.
* function.c (shell_completed, msdos_openpipe, func_shell_base): Add
shell_completed() to handle the completion of the shell, by setting
.SHELLSTATUS. Call it where needed.
* job.c (child_handler): Call shell_completed().
* tests/scripts/functions/shell: Add tests for .SHELLSTATUS.
2015-07-12 Paul Smith <psmith@gnu.org>
* tests/scripts/misc/fopen-fail: [SV 42390] Increase test timeout.
* Makefile.am (check-regression): Force ulimit -n for fopen-fail test.
* job.c: [SV 43936] Check sigaction for error return.
[SV 45049] Check for '$' being the last character in a string.
* expand.c (variable_expand_string): Add a single '$' if '$' ends the
string.
* read.c (find_char_unquote, get_next_mword): Stop if '$' ends the
string.
* variable.c (parse_variable_definition): Ditto.
* read.c (unescape_char): [SV 45050] Handle final backslashes.
If the last thing in the string to be unescaped is a backslash,
stop without reading beyond the end of the string.
* strcache.c: [SV 45275] Handle very long strings.
Our previous behavior for handling too-long strings involved
increasing the size of the default string cache buffer, but the
implementation was incomplete. Instead, create a one-off large
string cache entry and add it directly to the full cache list
without changing the default buffer size.
2015-07-12 Duncan Moore <duncan.moore@gmx.com> (tiny change)
* job.c [RISCOS]: Remove logic that is no longer required.
2015-07-12 Paul Smith <psmith@gnu.org>
* remake.c (update_file): [SV 44742] Keep double-colon rule status.
Fix suggested by Everett Boyer <EvBoyer@aol.com>
2015-07-10 James Johnston <johnstonj.public@codenest.com> (tiny change)
[SVN 45515] Check exit status of sub-make in subproc.bat
* subproc.bat: Exit when sub-make invocation fails.
2015-07-10 Eli Zaretskii <eliz@gnu.org>
[SV 45515] Ignore Windows-specific build artifacts
* .gitignore: Ignore *.exe, *.dll.a, *.lib, *pdb, and a few more MSVC
specific artifacts.
Suggested by James Johnston <johnstonj.public@codenest.com>
2015-02-28 Eli Zaretskii <eliz@gnu.org>
[SV 44348] Fix handling of shell widlcards on MS-Windows.
* job.c (construct_command_argv_internal): If shell wildcard
characters are found inside a string quoted with "..", give up the
fast route and go through the shell. Fixes Savannah bug #44348.
2015-01-27 John Malmberg <wb8tyw@qsl.net>
Fix bs-nl handling, exit and Environment for VMS.
This fix required a complete rewrite of the command parser vmsjobs.c
child_execute_job. The old parser had too many incorrect assumptions
about DCL commands and could not be repaired to extended.
The parser now more closely parses VMS commands and handles quoted
commands and redirection. Command File mode has been improved, but can
not fully support bs-nl syntax.
VMS Unix shell simulation has been improved.
* commands.c: vms_comma_separator is now a run-time setting.
* function.c: vms_comma_separator is now a run-time setting.
* function.c(func_basename_dir) now reports "[]" or "./" based on
VMS crtl runtime setting.
* job.c(start_job_command): VMS Handle empty commands propery.
* main.c: Add VMS environment variables for run-time settings.
* vms_legacy_behavior - Force older behavior.
* vms_comma_separator - Commas or spaces for separators.
* vms_unix_simulation - Enhanced Posix shell simulation features.
* Detect if VMS CRTL is set to report Unix paths instead of VMS.
* ':' and '>' are also MAP_DIRSEP on VMS.
* makeint.h: Add VMS run-time option variables.
* readme.vms: Update to current behavior.
* variable.c(define_variable_in_set): Fix VMS Environment variable
lookup.
* variable.c(define_automatic_variables): Remove some VMS specific
automatic variables and use the Unix ones instead.
* vms_export_symbol.c: Set max symbol size correctly.
* vmsjobs.c: child_execute_job() complete rewrite of VMS comand
parsing.
* vmsjobs.c(build_vms_cmd): VMS commmand building with shell simulation.
2014-12-27 Christian Boos <cboos@edgewall.org> (tiny change)
Fix $(shell) on hosts with 64-bit pid_t.
* function.c: Use pid_t for shell_function_pid.
* job.c: Likewise.
2014-10-20 Paul Smith <psmith@gnu.org>
* main.c (main): [SV 43434] Handle NULL returns from ttyname().
2014-10-20 Benedikt Morbach <benedikt.morbach@googlemail.com> (tiny change)
* tests/scripts/features/archives: [SV 43405] override AR variable.
2014-10-20 John Malmberg <wb8tyw@qsl.net>
Fix VMS implicit rules and UNIX paths.
This fixes VMS implicit rules and UNIX style pathname handling.
It also fixes some of the VMS style pathname handling, more work
there will be needed later.
TODO: There are other case insensitive platforms besides VMS.
We need to find out why there is extra VMS code for this. This
indicates either the extra VMS code is not needed, or the case
insensitive support may not be complete on the other case
insensitive platforms.
* default.c: Add missing definitions to default_suffix_rules[] and
default_variables[].
TODO: As it is important that VMS DCL mode definitions must always
be a superset of UNIX definitions, a better way of maintaining the
VMS DCL mode definitions should be devised.
* dir.c (downcase_inplace): Add a reentrant downcase() routine.
Add future support for VMS 8.2+ _USE_STD_STAT macro which will
disable a lot of VMS specific code from compiling.
(dir_file_exists_p): vmsify filename only if directory name has VMS
directory delimiters.
(file_exists_p): Handle both VMS and UNIX directories.
(file_impossible): Handle both VMS and Unix directories. Track
whether a VMS format path is needed for the return value.
* file.c (lookup_file): Check if vmsify is needed; handle UNIX paths.
* implicit.c (pattern_search): Enable UNIX paths.
* read.c (parse_file_seq): Enable UNIX paths.
* remake.c (f_mtime): Fix gpath_search call for VMS paths.
* rule.c (count_implicit_rule): Enable UNIX paths, Fix VMS paths.

[SV 42447]: VMS simulate exporting symbols
This also includes fixing the most of the exit handling code for VMS.
Self tests:
Previously about 94 Tests in 36 categories fail.
Now about 45 tests in 22 categories fail.
Because some tests do not properly clean up, the number of tests that
fail can vary by one or two test cases between consecutive runs.
* Makefile.am: Add new VMS files.
* job.c: add prototype for vms_strsignal().
* job.c: (child_error): Remove VMS specific code as no longer needed.
* job.c: (reap_children): The VMS specific code was setting the
status to 0 instead of setting it to the proper exit status.
* job.h: Add vms_launch_status to struct child.
* main.c: (main): Use environment variables for options to use MCR
* instead of a foreign command, and to always use command files for
subprocesses.
For VMS use (set_program_name) routine which is common to ports of
other GNU packages to VMS to set the program name used internally.
Use (vms_putenv_symbol) to set up symbols to be visible in child
programs, including recursive make launched by execve()
Start of Bash shell detection code for VMS.
* makefile.com: Need nested_include=none for building on VMS search
lists. Add vms_progname, vms_exit, and vms_export_symbol.

prototypes for new VMS routines. Remove VMS-specific failure codes.
* vmsjobs.c: Add VMS POSIX exit code constants.
(_is_unixy_shell): Detect Bash shell.
(vms_strsignal): simulate strsignal() on VMS.
(vmsHandleChildTerm): fix to properly report failed LIB$SPAWN() exit
status codes. Remove code that duplicated code in job.c.
(child_execute_job): Export environment symbols before spawning a
child and restore afterward unless option to use command files for
subprocesses is set. Improve handling of UNIX null commands ":".
* vms_exit.c: Provides vms_exit() to detect if an exit code is UNIX
or VMS, and converts the UNIX code into a VMS exit code.
* vms_export_symbol.c: Routines to create DCL symbols that work like
shell aliases or exported shell symbols and clean them up on exit.
* vms_export_symbol_test.com: Unit test for vms_export_symbol.c
* vms_progname.c: New file: VMS specific replace for progname.c that
is used in some GNU projects.
2014-10-20 John Malmberg <wb8tyw@qsl.net>
Set up for running tests on VMS.
* run_make_tests.pl: set $port_type to be 'VMS-DCL' when the test are
run from the VMS DCL Interpreter. When the tests are run from GNV
on VMS, the $port_type will be 'UNIX'.
* run_make_tests.com: VMS search list support. This is needed for
using a search list such as prj_root = lcl_root:,vms_root:,src_root:
for building and testing.

and set it only if NDEBUG is not defined, to avoid compiler
warnings.
Treat redirection of standard handles on Windows as it is done on Unix.
* job.c (start_job_command) [WINDOWS32]: Compute outfd and errfd
as on Posix platforms, and pass the results to process_easy.
* function.c (windows32_openpipe) [WINDOWS32]: Accept an
additional argument ERRFD and use it for redirecting the standard
error handle passed to the subprocess.

Fix and enhance VMS library support.
* ar.c: fix VMS library search for members, which do not have
suffixes, aka filename extensions.
* arscan.c: fix time conversion and library callback routines.
* default.c: more suffixes and automatically create the VMS library
if it doesn't exists.
Enhance VMS exporting make environment variables.
* config.h-vms.template: add feature macro USE_DCL_COM_FILE to always
write a DCL command file, enabled by default.
* vmsjobs.c: with USE_DCL_COM_FILE enabled write make variables as DCL
symbol assignments into the command file. This enables printing
directory and make level info for recursive use of make. This also
enables forced DCL symbol substitution in the actions.
Fix VMS automatic variable expansion
* function.c: add VMS code to func_notdir_suffix and func_basename_dir
to work on comma separated lists; this fixes the expansion of
$(^D), $(+D) and the F variants for VMS.
* main.c [VMS]: Say that parallel jobs (-j) are not supported on VMS
Enhance/fix VMS ONESHELL implementation and command execution
* job.c, vmsjobs.c: fix some double quote and new line handling;
implement ONESHELL with writing multiple lines into one DCL command
procedure; in ONESHELL allow VMS/make internal redirection only on the
first line; fix the created DCL command procedure, which didn't abort
on errors; return correct exit status from the DCL command procedure;
preserve current procedure verification; make the generated command
procedure more robust.
Enhance/fix VMS setting of program name, MAKE/MAKE_COMMAND variables
* default.c, main.c, makeint.h, vmsfunctions.c: prefix argv[0] with
"mcr " for MAKE/MAKE_COMMAND and set the program name to the image
filename (without the .exe;version)
* vmsfunctions.c: remove obsolete code
* vmsify: use xmalloc
Enhance/fix VMS exit code handling.

* vmsjobs.c: save and return VMS style exit code.
Enhance/fix VMS multi-line support.
* job.c: split the command line at a newline.
* default.c, vmsjobs.c: change ECHO variable to a pseudo builtin,
which ensures that the VMS/DCL ECHO ("write sys$output") is used
and is correctly quoted.
* vmsjobs.c: remove unused builtin 'rm'.
* config_flags_pm.com, [RENAMED test_make.com] run_make_tests.com:
Moved into tests directory.
Enhance/fix VMS build environment

(make_command_line): Kludgey feature: if full_exec_path is "-c",
assume that argv[0] is not to be skipped, as it holds the command
string to be passed to the shell.
2013-10-20 Paul Smith <psmith@gnu.org>
* glob.c (glob) [SV 18123]: Cherry-pick glibc fix
Apply commit a471e96a5352a5f0bde6d32dd36d33524811a2b1 from

[SV 40139] Modify "missing separator" for better translation
Add support for updating the GNU make web pages.
Add makefile rules for updating the http://www.gnu.org/software/make
web pages, including the online GNU make manual.
Convert to auto-generated ChangeLog files.
Rename existing ChangeLog files so they won't be distributed.
Add targets to maintMakefile to generate ChangeLog from the Git
repository. This will require a version of gnulib be available.
Because ChangeLog is auto-generated, we have to switch our
automake mode to "foreign" or it will complain and fail.
Set up for the next release.
