2014-12-10Use -Werror by default, add --disable-werror.Joseph Myers1-1/+4
As discussed starting at <https://sourceware.org/ml/libc-alpha/2014-11/msg00323.html>, this patch makes the glibc build use -Werror by default to avoid accidentally adding new warnings to the build. The configure option --disable-werror can be used to disable this. -Wno-error=undef is temporarily used because the build isn't clean regarding -Wundef warnings. The idea is that once the remaining -Wundef warnings have been cleaned up (in at least one configuration), -Wno-error=undef will be removed. I get a clean build and test on x86_64 (GCC 4.9 branch) with this patch. The expectation is that this may well break the build for some other configurations, and people seeing such breakage should make appropriate fixes to fix or suppress the warnings for their configurations. In some cases that may involve using pragmas as the right fix (I think that will be right for the -Wno-inline issue for MIPS I referred to in <https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, for example), in some cases -Wno-error in sysdeps makefiles (__restore_rt in MIPS sigaction, for example), in some cases substantive fixes for the warnings. Note that if, with a view to listing all the warnings then fixing them all, you just look for "warning:" in output from building and testing with --disable-werror, you'll see lots of warnings from the linker about functions such as tmpnam. Those warnings can be ignored - only compiler warnings are relevant to -Werror, not linker warnings. * configure.ac (--disable-werror): New configure option.

2014-11-19Auto-generate libc-modules.hSiddhesh Poyarekar1-2/+38
Remove libc-modules.h from the tree and auto-generate it from soversions.i and the list of modules in the built-modules variable defined in Makeconfig. Macros generated have increasing numbered values, with built-modules having lower values starting from 1, following which a separator value LIBS_BEGIN is added and then finally the library names from soversions.i are appended to the list. This allows us to conveniently differentiate between the versioned libraries and other built modules, which is needed in errno.h and netdb.h to decide whether to use an internal symbol or an external one. Verified that generated code remains unchanged on x86_64. * Makeconfig (built-modules): List non-library modules to be built.

2014-11-19Add new macro IN_MODULE to identify module in which source is builtSiddhesh Poyarekar1-1/+6
The current scheme to identify which module a translation unit is built in depends on defining multiple macros IS_IN_* and also defining NOT_IN_libc if we're building a non-libc module. In addition, there is an IN_LIB macro that does effectively the same thing, but for different modules (notably the systemtap probes). This macro scheme unifies both ideas to use just one macro IN_MODULE and assign it a value depending on the module it is being built into. If the module is not defined, it defaults to MODULE_libc. Patches that follow will replace uses of IS_IN_* variables with the IS_IN() macro. libc-symbols.h has been converted already to give an example of how such a transition will look. Verified that there are no relevant binary changes. One source change that will crop up repeatedly is that of nscd_stat, since it uses the build timestamp as a constant in its logic. * Makeconfig (in-module): Get value of libof set for the translation unit. (CPPFLAGS): Use $(in-module). * Makerules: Don't suffix routine names for nonlib. * include/libc-modules.h: New file. * include/libc-symbols.h: Include libc-modules.h (IS_IN): New macro to replace IS_IN_* macros. * elf/Makefile: Set libof-* for each routine. * elf/rtld-Rules: Likewise. * extra-modules.mk: Likewise. * iconv/Makefile: Likewise. * iconvdata/Makefile: Likewise. * locale/Makefile: Likewise. * malloc/Makefile: Likewise. * nss/Makefile: Likewise. * sysdeps/gnu/Makefile: Likewise. * sysdeps/ieee754/ldbl-opt/Makefile: Likewise. * sysdeps/unix/sysv/linux/Makefile: Likewise. * sysdeps/s390/s390-64/Makefile: Likewise. * nscd/Makefile: Set libof-* for each routine.

2014-09-26Clean up gnu/lib-names.h generation (bug 14171).Joseph Myers1-40/+1
This patch eliminates the mixture of SONAME information in shlib-versions files and SONAME information used to generate gnu/lib-names.h in makefiles, with the information in the makefiles being removed so all this information comes from the shlib-versions files. So that gnu/lib-names.h supports multiple ABIs, it is changed to be generated on the same basis as gnu/stubs.h: when there are multiple ABIs, gnu/lib-names.h is a wrapper header (the same header installed whatever ABI is being built) and separate headers such as gnu/lib-names-64.h contain the substantive contents (only one such header being installed by any glibc build). The rules for building gnu/lib-names.h were moved from Makeconfig to Makerules because they need to come after sysdeps makefiles are included (now that "ifndef abi-variants" is a toplevel conditional on the rules rather than $(abi-variants) being evaluated later inside the commands for a rule). Tested for x86_64 and x86 that the installed shared libraries are unchanged by this patch, and examined the installed gnu/lib-names*.h headers by hand. Also tested the case of a single ABI (where there is just a single header installed, again like stubs.h) by hacking abi-variants to empty for x86_64.

2014-09-16Remove bitrotten --enable-oldest-abi (bug 6652).Joseph Myers1-5/+1
This patch removes the --enable-oldest-abi configure option, which has long been bitrotten (as reported in bug 6652). The principle of removing this option was agreed in the thread starting at <https://sourceware.org/ml/libc-alpha/2013-07/msg00174.html>. Tested for x86_64 and x86 that the installed shared libraries other than libc.so are unchanged by this patch and that libc.so disassembly and symbol versions are unchanged (debug info changes because of changed line numbers in csu/version.c). [BZ #6652] * Makeconfig (soversions-default-setname): Remove variable.

2014-09-12Remove configuration name patterns from shlib-versions.Joseph Myers1-3/+0
This patch removes the first column (patterns matching configuration names) from shlib-versions, leaving shlib-versions entry selection based purely on sysdeps directories. An implication of this removal is that the default for any non-Linux ports using NPTL will be the same SONAMEs for NPTL libraries as for Linux (as those defaults, previously limited to .*-.*-linux.*, are left in nptl/shlib-versions and nptl_db/shlib-versions). Special host_os handling in configure.ac that was purely for shlib-versions is removed. (The host_os setting is still used for libc-abis - see <https://sourceware.org/ml/libc-alpha/2014-01/msg00375.html> regarding that - but no entries there are affected by this change.) Tested on x86_64 and x86 that the installed shared libraries are unchanged by this patch. * scripts/soversions.awk: Do not handle configuration names. * Makeconfig ($(common-objpfx)soversions.i): Do not pass cpu, vendor and os variables to soversions.awk. * configure.ac: Do not modify gnu-* host_os. * configure: Regenerated * shlib-versions: Remove first column with configuration names. * nptl/shlib-versions: Likewise. * nptl_db/shlib-versions: Likewise. * sysdeps/hppa/shlib-versions: Likewise. * sysdeps/m68k/shlib-versions: Likewise. * sysdeps/mach/hurd/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/aarch64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/alpha/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/arm/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/hppa/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/ia64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/microblaze/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/mips/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sh/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/tile/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/shlib-versions: Likewise. libidn/ChangeLog: * shlib-versions: Remove first column with configuration names.
2014-09-10Turn on -Werror=implicit-function-declarationFlorian Weimer1-1/+1
GCC 4.4, the minimum compiler version, supports this option. Unlike other warnings, -Wimplicit-function-declaration warnings should be independent of compiler versions, so this change should not cause compiler-specific build failures.
2014-06-27Remove shlib-versions ABI names support.Joseph Myers1-1/+0
shlib-versions files can contain ABI lines that map triplets to a canonical ABI name. This name was once used for various purposes where test baseline files for different ABIs went in a single directory; now these purposes use sysdeps files, generation of headers which have per-ABI variants uses abi-variants and related Makefile variables and the shlib-versions ABI names are unused. This patch duly removes those lines and associated build system support for them. Tested for x86_64 (both a full testsuite run and confirming the installed shared libraries are unchanged by the patch). * Makeconfig ($(common-objpfx)soversions.mk): Do not generate abi-name definition. * scripts/soversions.awk: Do not handle or generate ABI lines. * shlib-versions: Remove ABI entries. * sysdeps/powerpc/nofpu/shlib-versions: Remove file. * sysdeps/x86_64/x32/shlib-versions: Remove ABI entry.
2014-06-06Don't require test wrappers to preserve environment variables, use more ↵Joseph Myers1-9/+36
consistent environment. 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.

This patch makes the configure adds -D_CALL_ELF=1 when compiler does not define _CALL_ELF (versions before powerpc64le support). It cleans up compiler warnings on old compiler where _CALL_ELF is not defined on powerpc64(be) builds. It does by add a new config.make variable for configure-deduced CPPFLAGS and accumulate into that (confix-extra-cppflags). It also generalizes libc_extra_cflags so it accumulates in sysdeps configure fragmenets.
2014-03-14Do not terminate default test runs on test failure.Joseph Myers1-0/+7
This patch is an updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00198.html> and <https://sourceware.org/ml/libc-alpha/2014-03/msg00180.html>. Normal practice for software testsuites is that rather than terminating immediately when a test fails, they continue running and report at the end on how many tests passed or failed. The principle behind the glibc testsuite stopping on failure was probably that the expected state is no failures and so any failure indicates a problem such as miscompilation. In practice, while this is fairly close to true for native testing on x86_64 and x86 (kernel bugs and race conditions can still cause intermittent failures), it's less likely to be the case on other platforms, and so people testing glibc run the testsuite with "make -k" and then examine the logs to determine whether the failures are what they expect to fail on that platform, possibly with some automation for the comparison. This patch switches the glibc testsuite to the normal convention of not stopping on failure - unless you use stop-on-test-failure=y, in which case it behaves essentially as it did before (and does not generate overall test summaries on failure). Instead, the summary tests.sum may contain tests that FAILed. At the end of the test run, any FAIL or ERROR lines from tests.sum are printed, and then it exits with error status if there were any such lines. In addition, build failures will also cause the test run to stop - this has the justification that those *do* indicate serious problems that should be promptly fixed and aren't generally hard to fix (but apart from that, avoiding the build stopping on those failures seems harder). Note that unlike the previous patches in this series, this *does* require people with automation around testing glibc to change their processes - either to start using tests.sum / xtests.sum to track failures and compare them with expectations (with or without also using "make -k" and examining "make" logs to identify build failures), or else to use stop-on-test-failure=y and ignore the new tests.sum / xtests.sum mechanism. (If all you check is the exit status from "make check", no changes are needed unless you want to avoid test runs continuing after the first failure.) Tested x86_64. * scripts/evaluate-test.sh: Handle fourth argument to determine whether test run should stop on failure. * Makeconfig (stop-on-test-failure): New variable. (evaluate-test): Pass fourth argument to evaluate-test.sh based on $(stop-on-test-failure). * Makefile (tests): Give a summary of results from testing and exit with failure status if they include an ERROR or FAIL.

2014-03-07conformtest: split up running of tests from makefile.Joseph Myers1-2/+5
This patch changes the logic by which header conformance tests are run so that the makefiles run the tests for each (standard, header) pair separately rather than as a single test (there are 518 such pairs being tested at present). Since these tests are slow and previously couldn't be run in parallel, this obviously speeds up the whole test run significantly when using parallel testing. There are other benefits. These tests can now be marked as expected to fail at the level of (standard, header) pairs, meaning that regressions introduced by a header change are much more likely to be spotted (of course, such a regression could be a bug in the header or in the expectations, most of which have not been properly checked against the relevant standards). The patch introduces lists in conform/Makefile of the headers to test for each standard, with a new (quick) test for each standard that the list agrees with the set of headers for which there are in fact nonempty expectations for that standard. This means that each of the 518 pairs being tested is actually something meaningful to test rather than a null test. I also hope to use these lists of headers in various standards in future tests for namespace violations where a function in a standard is implemented to call a non-reserved name for a function outside that standard. Although there are a lot of tests now marked as expected to fail, I expect most of those to be easy to fix (whether with fixes to the expectations, the headers or both - if fixing a header bug, of course file it in Bugzilla first); only a limited number are likely to reflect actual missing features in glibc. Tested x86_64 (GCC 4.7 branch). It's quite possible some failures vary from platform to platform, in which case either additional XFAILs can be added here, or platform-specific header bugs (if applicable) the failures show up can be fixed. I made XFAILs unconditional for tests that should only fail for GCC 4.6 and earlier; we could make the GCC version available in the makefiles and condition these, but simply moving the XFAILing to a finer granularity seems a clear improvement on the previous state of the whole of conformtest being XFAILed. * Makeconfig (test-xfail-name): New variable.

2014-02-27Support expected failures in .test-result files.Joseph Myers1-1/+4
This patch, an updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00195.html>, makes it possible for .test-result files for individual tests to contain XPASS and XFAIL rather than PASS and FAIL in cases where failure is expected. This replaces the marking of two individual tests with "-" to cause them to be expected at makefile level to fail; evaluate-test.sh will ensure it exits with status 0 for an expected failure. Tested x86_64. * scripts/evaluate-test.sh: Take new argument indicating whether failure is expected. * Makeconfig (evaluate-test): Pass argument to evaluate-test.sh indicating whether failure is expected. * conform/Makefile (test-xfail-run-conformtest): New variable. ($(objpfx)run-conformtest.out): Don't expect to fail at makefile level. * posix/Makefile (test-xfail-annexc): New variable. ($(objpfx)annexc.out): Don't expect to fail at makefile level.
2014-02-15Generate .test-result files for ordinary tests.Tomas Dohnalek1-0/+7
This patch, an updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00193.html>, starts the process of generating explicit PASS or FAIL status for individual glibc tests. It's based on Tomas Dohnalek's patch <https://sourceware.org/ml/libc-alpha/2012-10/msg00278.html>, but is deliberately more minimal: it doesn't try to cover any tests outside of $(tests) / $(xtests) (that's for a later patch), nor does it put the result together in an overall summary file (again, a later patch): it just generates the .test-result files. Thus, this patch keeps the overall logic for when a testsuite run finishes completely unchanged: a test failing will terminate the run. I think we *should* move to a more conventional approach where plain "make check" does not terminate for an individual test failure, unless e.g. you say "make stop-on-test-failure=y check", but that sort of policy change is best done as a separate patch once the infrastructure is in place to generate summary files for completed test runs (which will entirely consist of PASS and XFAIL lines if the testsuite run reaches the point of generating them, until such a policy change is made). Tested x86_64. 2014-02-14 Tomas Dohnalek <tdohnale@redhat.com> Joseph Myers <joseph@codesourcery.com> * Makeconfig (test-name): New variable. (evaluate-test): Likewise. * Makerules (do-test-clean): Remove .test-result files.

2013-04-11Don't use run-via-rtld-prefix for anything other than testsSiddhesh Poyarekar1-3/+4
run-via-rtld-prefix checks whether the program to be run is a static test and skips if it is. This is fine, except that it assumes that the program to be run is the second $^, which is true only for tests. This change creates an rtld-prefix, which is simply the dynamic linker prefix with the necessary arguments and uses that in the non-test targets.
