* 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.
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.
We already use undef makefile strings to mean "re-use the previous
makefile", so if the string is empty we'll assume it means "don't
use a makefile at all" (don't add -f).
* tests/run_make_tests.pl (run_make_test): If the makefile string
is empty, don't create a makefile or add -f.
* tests/scripts/features/include: Change empty makefile to "\n".
* tests/scripts/misc/close_stdout: Ditto.
* tests/scripts/options/dash-r: Ditto.
* tests/scripts/features/errors: Match Windows-specific errors.
* tests/scripts/features/targetvars: Match Windows-specific errors.
* tests/scripts/misc/general4: Match Windows-specific errors.
GNU make must recognize some special targets as they are defined.
Because of the way targets are defined, we were not recognizing these
special targets until we were handling the NEXT statement. However
that's too late for some special targets such as .POSIX etc. which can
change the behavior of make during parsing.
Check for special targets earlier, as soon as we've finished parsing
the target introduction line (before we've even parsed the recipe).
* NEWS: Mention the change.
* src/read.c (check_specials): New function to look for special
targets. Move checks from eval() and record_files() to this new
function.
(eval): Call check_specials() after we've completed parsing the target
introduction line. Move default goal detection to check_specials().
(record_files): Move handling of .POSIX, .SECONDEXPANSION, and
.ONESHELL to check_specials().
* tests/scripts/misc/bs-nl: Remove workaround for late .POSIX issue.
* tests/scripts/targets/POSIX: Add a comment.
When using execvp() if $PATH is not present in the environment
it will automatically search the system default PATH string. Emulate
this by passing the system default PATH to find_in_given_path() if
we don't find PATH in the environment.
* src/job.c (child_execute_job): Use confstr(_CS_PATH) if PATH is not
found.
Rather than having an %extraENV that is added to the default %ENV
and resetting %ENV _before_ each test, allow the test setup to
modify %ENV directly as needed then reset %ENV _after_ each test.
* tests/test_driver.pl: Remove unused %extraENV.
(resetENV): Don't add in %extraENV.
(_run_command): Reset after we run the command rather than before.
* tests/scripts/features/export: Convert %extraENV to %ENV
* tests/scripts/features/jobserver: Ditto
* tests/scripts/features/parallelism: Ditto

This reverts commit 6264deece3.
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.
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 $cwddir variable.
* tests/scripts/features/reinvoke: Add missing semicolon.
* tests/scripts/features/vpath2: Avoid non-existent variable.
* tests/scripts/functions/foreach: Escape variables.
* tests/scripts/misc/bs-nl: Remove non-existing \v escape sequence.
* tests/scripts/misc/general4: Use handy create_file().
* tests/scripts/options/dash-C: Use Cwd/$cwddir.
* tests/scripts/options/dash-I: Use subst_make_string() and #PWD#.
* tests/scripts/options/symlinks: Use File::Spec.
* tests/scripts/targets/DEFAULT: Use create_file and run_make_test.
* tests/scripts/variables/CURDIR: Use run_make_test.
* tests/scripts/variables/automatic: Remove extraneous "\".
* tests/scripts/vms/library: Remove extra "my" and extraneous "\".
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.
* tests/scripts/features/jobserver: Windows doesn't use pipes
* tests/scripts/functions/shell: Don't test kill -2 on Windows
* tests/scripts/misc/bs-nl: Windows doesn't handle single quotes
* tests/scripts/misc/general3: Ditto.
* main.c (main): Sanitize program name detection on Windows.
* makeint.h: 'program' is a const string on all platforms now.
* tests/run_make_tests.bat: Windows bat file to invoke tests
* tests/test_driver.pl: Obtain system-specific error messages.
(get_osname): Compute the $port_type here. Add more $osname checks
for different Windows Perl ports.
(_run_command): Rewrite the timeout capability to work properly
with Windows. Don't use Perl fork/exec; instead use system(1,...)
which allows a more reliable/proper kill operation.
Also, allow options to be given as a list instead of a string, to
allow more complex quoting of command-line arguments.
* tests/run_make_tests.pl (run_make_with_options): Allow options
to be provided as a list in addition to a simple string.
(set_more_defaults): Write sample makefiles and run make on them
instead of trying to run echo and invoking make with -f-, to avoid
relying on shell and echo to get basic configuration values. Also
create a $sh_name variable instead of hard-coding /bin/sh.
* tests/scripts/features/archives: Skip on Windows.
* tests/scripts/features/escape: Use list method for passing options.
* tests/scripts/features/include: Use system-specific error messages.
* tests/scripts/features/output-sync: "Command not found" errors
generate very different / odd output on Windows. This needs to be
addressed but for now disable these tests on Windows.
* tests/scripts/functions/abspath: Disable on Windows.
* tests/scripts/functions/file: Use system-specific error messages.
* tests/scripts/functions/shell: "Command not found" errors generate
very different / odd output on Windows. This needs to be addressed
but for now disable these tests on Windows.
* tests/scripts/misc/close_stdout: Disable on Windows.
* tests/scripts/options/dash-k: Use system-specific error messages.
* tests/scripts/options/dash-l: Disable on Windows.
* tests/scripts/options/eval: Use list method for passing options.
* tests/scripts/options/general: Skip some non-portable tests.
* tests/scripts/targets/ONESHELL: Skip some non-portable tests.
* tests/scripts/targets/POSIX: Skip some non-portable tests.
* tests/scripts/variables/MAKEFILES: Skip some non-portable tests.
* tests/scripts/variables/SHELL: Use a makefile not -f- for testing.
* makeint.h: Change MAP_SPACE to MAP_NEWLINE, and add MAP_PATHSEP
and MAP_SPACE which is now MAP_BLANK|MAP_NEWLINE. Create
NEW_TOKEN(), END_OF_TOKEN(), ISBLANK(), ISSPACE() macros.
* main.c (initialize_stopchar_map): Set MAP_NEWLINE only for
newline characters.
* Convert all uses of isblank() and isspace() to macros.
* Examine all uses of isblank() (doesn't accept newlines) and
change them wherever possible to ISSPACE() (does accept newlines).
* function.c (func_foreach): Strip leading/trailing space.
* variable.c (parse_variable_definition): Clean up.
* tests/scripts/functions/foreach: Test settings and errors.
* tests/scripts/functions/call: Rewrite to new-style.
* tests/scripts/misc/bs-nl: Add many more tests for newlines.
We fixed Savannah 16670 but that broke previously-working makefiles
that relied on the GNU make behavior. The POSIX behavior doesn't
seem to me to be better, and can be obtained using GNU make as well,
so put it back as the default behavior and require .POSIX to
get the POSIX behavior.
Add a new section to the manual discussing backslash/newline handling.
Update the test suite.
- Fix Savannah bug #17752
- Test suite:
* When tests fail keep a "run" file containing the command invoked.
* Support for the Valgrind "memcheck" and "massif" tools.
Allows the user to reset the prefix character for introducing recipe lines
from the default (tab) to any other single character, and back again.
Also, reworked the manual to consistently use the word "recipe" to describe
the set of commands we use to update a target, instead of the various
phrases used in the past: "commands", "command lines", "command scripts",
etc.
I decided this feature was too impacting to make the permanent default
behavior. This set of changes makes the default behavior of make the
old behavior (no second expansion). If you want second expansion, you
must define the .SECONDEXPANSION: special target before the first target
that needs it.
This set of changes ONLY fixes explicit and static pattern rules to work
like this. Implicit rules still have second expansion enabled all the
time: I'll work on that next.
Note that there is still a backward-incompatibility: now to get the old
SysV behavior using $$@ etc. in the prerequisites list you need to set
.SECONDEXPANSION: as well.
check for this and exit with an error.
The closeout.c version from gnulib pulls in too much other stuff, and
gnulib requires an ANSI C 89 compliant compiler, while GNU make (so far)
still wants to work on K&R.
* New function: $(info ...)
* Disallow $(eval ...) to create prereq relationships inside command scripts
(caused core dumps)
* Try to allow more tests to succeed in Windows/DOS by sanitizing CRLF and \
* Various bug fixes and code cleanups (see the ChangeLog entry)
