Original patches provided by Igor Todorovski <itodorov@ca.ibm.com>
Reworked by Paul Smith <psmith@gnu.org>.
Thanks to IBM for providing a test system.
* NEWS: Announce support.
* AUTHORS: Ditto.
* README.zOS: Provide details on building GNU Make on z/OS.
* build.sh (get_mk_var): z/OS sh has a strange bug which causes it to
generate extra lines of output: rework the function to print output
as we compute it instead of collecting it into a variable, which
works around this bug.
* src/makeint.h: Declare MK_OS_ZOS if we're building for z/OS.
* src/arscan.c: Don't include <ar.h> on z/OS.
* src/job.c: We can't change environ in ASCII mode on z/OS.
* src/main.c: Ditto. Also we can't use pselect() on z/OS.
* src/posixos.c: pselect() seems to hang on z/OS: don't use it.
* tests/run_make_tests.pl: Handle different exit codes on z/OS.
* tests/test_driver.pl: Preserve some special z/OS env.vars.
Add special checks to output comparisons when on z/OS.
* tests/scripts/features/archives: Don't validate names. Don't
try to compile empty files as IBM compilers complain.
* tests/scripts/features/shell_assignment: Fix octal value of #.
* tests/scripts/features/temp_stdin: Don't print "term".
* tests/scripts/functions/shell: Handle shell exit codes.
* tests/scripts/targets/ONESHELL: Ditto.
* tests/scripts/targets/POSIX: sh -x prints differently.
* tests/scripts/variables/SHELL: Ditto.
Compare the timestamp of the object file (if it exists) with the
archived object and if the object file is newer, ensure it's updated
in the archive.
* NEWS: Announce the new capability.
* doc/make.texi (Dangers When Using Archives): Explain how to enable
parallel builds with archives.
* src/remake.c (f_mtime): For archive element files check the mod
time of the object file (if it exists) against the archive object
(if it exists).
* tests/scripts/features/archives: Add tests for this capability.
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.
* tests/config-flags.pm.W32: Create a predefined Windows file.
* Makefile.am (test_FILES): Add it to the distribution.
* build_w32.bat: Install tests/config-flags.pm if not existing.
* tests/run_make_tests.pl (get_config): Create new function.
* tests/scripts/features/archives: Call get_config() rather than
using %CONFIG_FLAGS directly.
* tests/scripts/features/load: Ditto.
* tests/scripts/features/loadapi: Ditto.
* tests/scripts/functions/wildcard: Ditto.
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 "\".
* 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.
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.
Upated to match change to run_make_tests and some future fixes to
make on VMS.
* arscan.c: Use ANSI compatible pragmas instead of VAX C extensions.
* tests/scripts/features/archives: Fix tests to use VMS rules and
answers when running on VMS and using DCL as a shell.
* tests/scripts/features/vpath3: Fix epected answer on test when
run on VMS.
* tests/scripts/vms/library: (New) Test the VMS library rules that
are not tested by existing tests.
Don't dup stdout into stderr in the test suite.
Don't rely on $port_type eq "UNIX" to mean case-preserving.
Check against the real output of ar when creating archives.
