* src/read.c (eval): If "missing separator" appears to be due to
missing space after ifeq/ifneq, give a hint about the error.
* tests/scripts/misc/failure: Check for these types of failures.
* tests/scripts/variables/special: Move error checking unrelated
to special variables, to misc/failure.
If make cannot create a temporary lock file for output sync, continue
without output sync enabled rather than dying.
However, if make cannot store a makefile from stdin to a temporary
file that is still a fatal error.
* misc.c (get_tmppath): Keep running on failure to generate a
temporary file name.
(get_tmpfd): Keep running on failure to get a temporary file.
(get_tmpfile): Keep running on failure to open a temporary file.
Ensure memory is freed if we return an error.
* posixos.c (os_anontmp): Keep running on failure to open an
anonymous temporary file.
* output.c (setup_tmpfile): Print an error on failure to create an
output sync lock file.
* main.c (main): Die on failure to store makefile from stdin to a
temporary file.
* tests/scripts/features/output-sync: Add tests.
* tests/scripts/features/temp_stdin: Ditto.
* src/posixos.c (jobserver_parse_auth): Don't invoke fatal() if we
can't connect to an existing jobserver: just keep going without it.
* src/w32/w32os.c (jobserver_parse_auth): Ditto.
* tests/scripts/features/jobserver: Add a test for invalid FIFO
auth files.
If we fail to read a directory show the directory name in the error
message. Pass struct directory instead of directory_contents to
allow that.
(dir_file_exists_p): Change dir_contents_file_exists_p caller.
(open_dirstrem): Ditto.
Tests that try to kill the make process were not behaving as expected
on OpenBSD: the signal was sent from make to its children but the
sleep didn't die. Something odd about the way the shell treats TERM.
To reduce platform dependencies add "term" to the helper tool and run
that instead of kill / sleep.
* tests/thelp.pl: Add a new operation "term" that takes a PID.
* tests/scripts/features/output-sync: Use it.
* tests/scripts/features/temp_stdin: Ditto.
* src/function.c (define_new_function): Don't keep a pointer to the
user-provided name of a user-defined function: if the .so is unloaded
it will point to garbage. Add the name to the strcache instead.
When tests compare the output they will try converting backslashes
to slashes to see if that works. When we compare using regex's,
we can't do that because backslashes can escape special characters.
* tests/test_driver.pl (compare_output): Clean up this function.
(compare_answer_vms) [VMS]: Comparing answers on VMS is complex;
move all of it into its own function returning 0/1.
(compare_answer): A new function to compare answers: return 0/1.
Remember the CRLF->LF conversion forever; only check \ -> / when
we compare strings, not regex's.
* src/config.h.W32 (strtoll, strtoull) [__TINYC__]: Redirect to
_strtoi64 and _strtoui64, respectively. Reported by Christian
Jullien <eligis@orange.fr>.
* tests/test_driver.pl: Preserve the LSAN_OPTIONS variable.
* tests/scripts/targets/ONESHELL: Don't set a local variable.
* tests/scripts/functions/let: Test empty let variable.
* src/posixos.c (osync_parse_mutex): Free existing osync_tmpfile.
* src/misc.c (get_tmpfd): Set umask() before invoking mkstemp().
* src/ar.c (ar_parse_name): Check invalid name (shouldn't happen).
* src/function.c (define_new_function): Free previous function entry
when replacing it with a new one.
* src/job.c (child_execute_job): Initialize pid for safety.
(construct_command_argv_internal): In oneshell mode ensure that the
returned argv has the right format (0th element is a pointer to the
entire buffer).
Although gnulib requires C99, most of the code does compile with a
C90 compiler (perhaps with a lot of warnings). Reinstate our C90
configuration test, and clean up a few C99 things that crept in.
* src/job.c (construct_command_argv_internal): Don't use loop-local
variables or C++ comments.
* src/read.c (eval_makefile): Don't use loop-local variables.
This was added in Perl 5.8 but some systems still only provide older
versions such as Perl 5.6. We don't really need it anyway.
Paul Eggert <eggert@cs.ucla.edu> reported this issue.
* tests/README: Update this to be a bit more modern.
* tests/test_driver.pl: Delete the $TEMPDIR variable.
* tests/scripts/features/temp_stdin: Use $temppath not $TEMPDIR.
We attempt to do this with POSIX::setlocale() but apparently on some
systems (AIX) this isn't sufficient. So, in addition force the LC
environment variables to use "C".
Reported by Dmitry Goncharov <dgoncharov@users.sf.net>.
* tests/run_make_tests.pl: Move the global setup into set_default().
Force the %ENV locale variables to use the ones we'll use when running
make, then reset them back again after we find error messages.
Using C shells (csh, tcsh) with make is known to be problematic due
to incorrect ways it handles open file descriptors, at least. If
the user's shell is *csh then don't try it during exec tests.
It seems that some of the test environments hit the 5s timeout on
some tests. Since it doesn't really matter, as long as we don't
hang forever, increase the timeout to 60s.
* tests/test_driver.pl: Increase $test_timout to 60. We don't need
to handle VMS timeouts specially anymore.
* tests/scripts/features/parallelism: We don't need to override the
default timeout anymore.
* tests/scripts/features/patternrules: Remove confusing comment.
If we fail during setup_tmpfile() we'll try to write an error, which
will invoke setup_tmpfile() again, etc. Avoid infinite recursion.
Original patch by Dmitry Goncharov <dgoncharov@users.sf.net>
* src/output.c (setup_tmpfile): Remember we're in this function and
return immediately if we enter it during recursion.
(message): Remember the starting location and use that instead of
fmtbuf.buffer.
(error): Ditto.
(fatal): Ditto.
Generating debug logs to stdout or stderr makes it impossible to
run tests etc. so create a dumb DBG facility to log to a temp file.
This exists only in maintainer mode and the DBG macro gives a
compile error if it's used in non-maintainer mode.
* src/makeint.h (DBG): Call dbg() in maintainer mode, else error.
(dbg): Define it in maintainer mode.
* src/misc.c (dbg): Open a log file for append, write, then close.
Some systems (HURD) use fully-dynamic pathnames, with no limit.
We can't support this without significant effort so for now set
PATH_MAX to a large value.
* src/makeint.h: Set PATH_MAX to 4096 if not set and MAXPATHLEN
is also not set. Remove MAXPATHLEN setting: we won't use it.
* src/misc.c (get_path_max): If we can't get the path max via
pathconf() use the default PATH_MAX.
* src/dir.c (find_directory) [W32]: Use MAX_PATH not MAXPATHLEN.
(local_stat) [W32]: Ditto.
* src/job.c (create_batch_file) [W32]: Ditto.
* src/remake.c (name_mtime) [W32]: Ditto.
* src/w32/w32os.c (os_anontmp) [W32]: Ditto.
The previous attempt to detect missing peer targets for implicit
rules had some holes. Move the detection to notice_finished_file().
* src/remake.c (check_also_make): If we don't have the current mtime
for the file, obtain it.
(update_goal_chain): Don't call check_also_make() here.
(check_dep): Ditto.
(notice_finished_file): If we finished running an implicit rule that
has also_make targets, invoke check_also_make().
* README.in: Add a section on running regression tests.
* Makefile.am (check-regression): Capture the test run output, and
on failure collect configure and test results into a tar file.
The GNU platform testers reported a number of test errors on
different systems; try to address them.
* tests/thelp.pl: A number of tests timed out with a 4-second
timeout. Increase the default timeout to 10 seconds.
* tests/run_make_tests.pl: Executing directories on cygwin behaves
differently in Perl than make so skip these tests there.
* tests/scripts/options/symlinks: Check for the symlink feature
in make, rather than whether the system supports them.
* tests/scripts/features/implicit_search: On some systems "false"
exits with a different exit code. Use the helper instead.
* tests/scripts/features/loadapi: Ditto.
* tests/scripts/features/output-sync: Sleep before make -f bar in
the first test as well as the second one.
* tests/scripts/features/exec: Skip on cygwin, which seems to
be "UNIX" but where scripts don't run normally.
* tests/scripts/misc/fopen-fail: Skip on cygwin, where make
eventually exits with exit code 0 and no error messages.
Original patch from Frank Heckenbach <f.heckenbach@fh-soft.de>.
* tests/scripts/features/output-sync: Introduce a sleep to let make
write its error message. Some systems use different names for
SIGTERM so match with a regex.
* tests/scripts/features/temp_stdin: Ditto.
On AIX getloadavg keeps errno intact when it fails, resulting in a
bogus error message from make.
* src/job.c (load_too_high): Reset errno before calling getloadavg.
Don't terminate when make's output is redirected to a pipe and the
reader exits early; e.g.:
$ echo 'all:; sleep 2' | make -f- -j2 -O |:
This lets us unlink temporary files, and tell the user that make was
not able to write its output.
Reported by Frank Heckenbach <f.heckenbach@fh-soft.de>.
* src/main.c (main): Ignore SIGPIPE.
* src/posixos.c (osync_clear): Fix a memory leak.
Original patch provided by Paul Eggert <eggert@cs.ucla.edu>.
GNU libc will generate a link-time warning if we use mktemp() even
though we are using it safely (we only use it with mkfifo()).
Avoid this and clean up some handling.
First, check all calls related to temporary files and exit with a
fatal error and a useful message if we can't obtain them. In some
situations it might be possible to continue with reduced capability
but it's not worth the effort.
On POSIX systems we can create anonymous temp files using O_TMPFILE
if it's supported, else if we're using the default location and we
have dup(2), we can use standard tmpfile() and get an FD from it.
If we need a named temp file and FILE* and we have mkstemp() we can
use that, else if we have fdopen() we can get a temp FD and open it.
If none of those are available all we can do is generate a temp name
then open it with fopen() which is not secure.
* src/makeint.h (get_tmpdir): Declare it for use elsewhere.
* src/misc.c (get_tmpdir): Make it public not static.
(get_tmptemplate): Simplify the implementation.
(get_tmppath): Only define this if we have to have it to avoid
warnings from GNU libc.
(get_tmpfd): Generate fatal errors on error.
(get_tmpfile): Ditto. Open files in "wb+" mode to match tmpfile().
Require a filename pointer (all callers want it).
* src/os.h (os_anontmp): Implement for posixos.c as well.
* src/posix.c (jobserver_setup): Don't use mktemp to avoid GNU libc
errors. Instead construct the FIFO name based on the PID.
(osync_setup): get_tmpfd() can't fail so don't check it.
(os_anontmp): If the system supports O_TMPFILE use it. If not, and
we want to create the temporary file in the default directory, we
can use tmpfile() then use dup() to copy the file descriptor.
* src/main.c (main): get_tmpfile() can't fail.
* src/vmsjobs.c (child_execute_job): get_tmpfile() can't fail.
* configure.ac: MK_CONFIGURE shows config.h was generated by configure.
* src/config.ami: Define MK_AMIGAOS.
* src/config.h-vms: Define MK_VMS.
* src/configh.dos: Define MK_DJGPP.
* src/config.h.W32: Define MK_W32 and WINDOWS32.
* src/build_w32.bat: Let WINDOWS32 be defined by config.h. Remove
unused setting of WIN32.
* src/job.c: Clean up use of WIN32.
* src/main.c: Ditto.
* tests/scripts/features/default_names: Ditto.
awk 'BEGIN {
print "x:"
for (i = 0; i < 65536; i++)
printf "\techo %d\n", i}
' | make -f -
Outputs only "make: 'x' is up to date." Larger values run only the
lines above 65536. Reported by Paul Eggert <eggert@cs.ucla.edu>.
* src/commands.c (chop_commands): Check the line count before it has
a chance to overflow. Use size_t for max count so it can't overflow.
Remove stray 'd' in diagnostic.
The README templates were not useful since the replacement step
didn't have anything to replace: rename them.
Rather than creating template files for the config variants, create
mkconfig.h.in containg PACKAGE_* variables to be replaced, and have
config variant header files include it. Note on POSIX we don't use
this, and continue to generate a single config.h.in file.
Use config.status to convert the README.in and mkconfig.h.in files
during distribution creation.
Modify all users of VERSION to use PACKAGE_VERSION instead.
* configure.ac: Use GNU Make not GNU make as the package name.
* README.in: Use GNU Make not GNU make.
* README.git: Remove references to README.W32.template.
* .gitignore: Update for new behavior.
* Basic.mk.template: Remove unused posix_SOURCES and VERSION, and
references to unshipped mk/Posix.mk
* Makefile.am: Add src/mkconfig.h as an extra dist file.
* bootstrap.bat: Rewrite mkconfig.h.in to mkconfig.h
* maintMakefile: Remove obsolete template files; add mkconfig.h.in.
* prepare_vms.com: Rewrite mkconfig.h.in to mkconfig.h
* mk/VMS.mk: Fix incorrect header file prerequisite.
* src/mkconfig.h.in: New file containing PACKAGE variables.
* src/config.ami: Include mkconfig.h.
* src/config.h.W32: Ditto.
* src/configh.dos: Ditto.
* src/config.h-vms: Ditto.
* src/version.c: Use PACKAGE_VERSION not VERSION.
* builddos.bat: Use env var settings for paths. Fix a typo in
expand.o. Add the missing load.o compilation and link. Enable
Guile support. Copy Basic.mk from the correct location.
* src/configh.dos.templage: DJGPP supports strtoll() and ssize_t
given new enough versions. Set preprocessor variables to 1 not 0.
