If the TZDEFRULES file was used to set the DST rules when $TZ didn't
provide any we need to make sure that the next time it is used we
recompute everything as __tzfile_default changes some setting from what is
provided by TZDEFRULES.
This patch updates the timezone code from tzcode 2015g. The Makefile
and README changes are based on those in Paul's patch
<https://sourceware.org/ml/libc-alpha/2015-05/msg00553.html>.
Tested for x86_64 and x86.

* timezone/zdump.c: Likewise.
* timezone/zic.c: Likewise.
* timezone/ialloc.c: Remove file.
* timezone/scheck.c: Likewise.
* timezone/Makefile (extra-objs): Remove variable.
($(objpfx)zic): Do not depend on scheck.o and ialloc.o.
(tz-cflags): Add -DHAVE_GETTEXT -DUSE_LTZ=0
-Wno-maybe-uninitialized.
(CFLAGS-zdump.c): Remove -fwrapv -DNOID -DHAVE_GETTEXT.
(CFLAGS-zic.c): Remove -DNOID -DHAVE_GETTEXT.
(CFLAGS-ialloc.c): Remove variable.
(CFLAGS-scheck.c): Likewise.
* timezone/README: Update list of files from tzcode.
GCC 6.0 (prelease) complains about time_t_min and time_t_max
not being used. These variables are not used in glibc but
are needed in other packages.
* timezone/Makefile (CFLAGS-zic.c): Add -Wno-unused-variable.
(CFLAGS-ialloc.c): Ditto.
(CFLAGS-scheck.c): Ditto.
Some distros build+install the timezone tools (zic/zdump/tzselect) outside
of glibc and use the upstream package directly. Add a configure flag to
glibc so they can disable install of those tools.
This allows tests to run & pass regardless of the configure flag. Only
the install of them is impacted.
The XT testdata install rules expect the testdata dir to already exist in
the build tree, but it doesn't actually create it. Instead, it relies on
the build-testdata define happening to be executed before it (which runs
zic which creates the dir). When we run in parallel though, it's easy to
hit a failure:
$ cd timezone
$ rm -rf $objdir/timezone/testdata
$ make check -j
...
cp testdata/XT1 .../timezone/testdata/XT1
cp: cannot create regular file '.../timezone/testdata/XT1': No such file or directory
Makefile:116: recipe for target '.../timezone/testdata/XT1' failed
make: *** [.../timezone/testdata/XT1] Error 1
make: *** Waiting for unfinished jobs....
The current timezone/ code from tzcode doesn't need
-Wno-strict-prototypes. This patch removes it from the CFLAGS
settings in timezone/Makefile.
Tested for x86_64 that glibc still builds OK with the patch applied.
* timezone/Makefile (CFLAGS-zdump.c): Remove
-Wno-strict-prototypes.
(CFLAGS-zic.c): Likewise.
(CFLAGS-ialloc.c): Likewise.
(CFLAGS-scheck.c): Likewise.
These tests were skipped by the use-test-skeleton conversion done in
commit 29955b5d because they did not have an `int main (void)'
declaration. Instead their `main' functions were declared with arguments
(i.e. argc, argv) even though they didn't use them.
Remove these arguments and include the test skeleton in these tests.
The Makefile rule is called one time for target %/UTC or %/Universal.
If the tests are run in parallel, UTC or Universal can trigger the rule.
This patch patch generates the second test-result file as a copy of the
generated one.
Thus the testsuite can rely on the existence of the test-result files
regardless of which target has triggered the rule.
ChangeLog:
* timezone/Makefile (%/UTC %/Universal):
Generate test-result files for UTC and Universal.
Allow building tests in a cross configuration without a test wrapper
defined. This is helpful for doing simple build testing of tests.

2014-09-30 Will Newton <will.newton@linaro.org>
* localedata/Makefile: Move assignment to tests-special

Various glibc build / install / test code has C locale settings that
are redundant with LC_ALL=C.
LC_ALL takes precedence over LANG, so anywhere that sets LC_ALL=C
(explicitly, or through it being in the default environment for
running tests) does not need to set LANG=C. LC_ALL=C also takes
precedence over LANGUAGE, since
2001-01-02 Ulrich Drepper <drepper@redhat.com>
* intl/dcigettext.c (guess_category_value): Rewrite so that LANGUAGE
value is ignored if the selected locale is the C locale.
* intl/tst-gettext.c: Set locale for above change.
* intl/tst-translit.c: Likewise.
and so settings of LANGUAGE=C are also redundant when LC_ALL=C is
set. One test also had LC_ALL=C in its -ENV setting, although it's
part of the default environment used for tests.
This patch removes the redundant settings. It removes a suggestion in
install.texi of setting LANGUAGE=C LC_ALL=C for "make install"; the
Makefile.in target "install" already sets LC_ALL_C so there's no need
for the user to set it (and nor should there be any need for the user
to set it).
If some build machine tool used by "make install" uses a version of
libintl predating that 2001 change, and the user has LANGUAGE set, the
removal of LANGUAGE=C from the Makefile.in "install" rule could in
principle affect the user's installation. However, I don't think we
need to be concerned about pre-2001 build tools.

One wart in the original support for test wrappers for cross testing,
as noted in
<https://sourceware.org/ml/libc-alpha/2012-10/msg00722.html>, is the
requirement for test wrappers to pass a poorly-defined set of
environment variables from the build system to the system running the
glibc under test. Although some variables are passed explicitly via
$(test-wrapper-env), including LD_* variables that simply can't be
passed implicitly because of the side effects they'd have on the build
system's dynamic linker, others are passed implicitly, including
variables such as GCONV_PATH and LOCPATH that could potentially affect
the build system's libc (so effectively relying on any such effects
not breaking the wrappers). In addition, the code in
cross-test-ssh.sh for preserving environment variables is fragile (it
depends on how bash formats a list of exported variables, and could
well break for multi-line variable definitions where the contents
contain things looking like other variable definitions).
This patch moves to explicitly passing environment variables via
$(test-wrapper-env). Makefile variables that previously used
$(test-wrapper) are split up into -before-env and -after-env parts
that can be passed separately to the various .sh files used in
testing, so those files can then insert environment settings between
the two parts.
The common default environment settings in make-test-out are made into
a separate makefile variable that can also be passed to scripts,
rather than many scripts duplicating those settings (for testing an
installed glibc, it is desirable to have the GCONV_PATH setting on
just one place, so just that one place needs to support it pointing to
an installed sysroot instead of the build tree). The default settings
are included in the variables such as $(test-program-prefix), so that
if tests do not need any non-default settings they can continue to use
single variables rather than the split-up variables.
Although this patch cleans up LC_ALL=C settings (that being part of
the common defaults), various LANG=C and LANGUAGE=C settings remain.
Those are generally unnecessary and I propose a subsequent cleanup to
remove them. LC_ALL takes precedence over LANG, and while LANGUAGE
takes precedence over LC_ALL, it only does so for settings other than
LC_ALL=C. So LC_ALL=C on its own is sufficient to ensure the C
locale, and anything that gets LC_ALL=C does not need the other
settings.
While preparing this patch I noticed some tests with .sh files that
appeared to do nothing beyond what the generic makefile support for
tests can do (localedata/tst-wctype.sh - the makefiles support -ENV
variables and .input files - and localedata/tst-mbswcs.sh - just runs
five tests that could be run individually from the makefile). So I
propose another subsequent cleanup to move those to using the generic
support instead of special .sh files.

In <https://sourceware.org/ml/libc-alpha/2014-01/msg00198.html> I
raised the question of counting miscellaneous dependencies of tests,
built on the host rather than the build system, as tests, so that when
test failures don't stop "make check" neither do those other builds on
the host, so that a flaky host doesn't stop "make check" from
producing a complete summary of test results. Brooks supported that
idea in <https://sourceware.org/ml/libc-alpha/2014-02/msg00301.html>.
This patch implements that change for all the examples I could find:
one message catalog in catgets/, locales in localedata/ and timezone
files in timezone/.
Tested x86_64.
* catgets/Makefile (tests-special): Add $(objpfx)sample.SJIS.cat.
($(objpfx)sample.SJIS.cat): Use $(evaluate-test).

In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I
noted it was necessary to add includes of Makeconfig early in various
subdirectory makefiles for the tests-special variable settings added
by that patch to be conditional on configuration information. No-one
commented on the general question there of whether Makeconfig should
always be included immediately after the definition of subdir.
This patch implements that early inclusion of Makeconfig in each
directory (which is a lot easier than consistent placement of includes
of Rules). Includes are added if needed, or moved up if already
present. Subdirectory "all:" targets are removed, since Makeconfig
provides one.
There is potential for further cleanups I haven't done. Rules and
Makerules have code such as
ifneq "$(findstring env,$(origin headers))" ""
headers :=
endif
to override to empty any value of various variables that came from the
environment. I think there is a case for Makeconfig setting all the
subdirectory variables (other than subdir) to empty to ensure no
outside value is going to take effect if a subdirectory fails to
define a variable. (A list of such variables, possibly out of date
and incomplete, is in manual/maint.texi.) Rules and Makerules would
give errors if Makeconfig hadn't already been included, instead of
including it themselves. The special code to override values coming
from the environment would then be obsolete and could be removed.
Tested x86_64, including that installed binaries are identical before
and after the patch.
