* Revert 4248f0da6ff9e7dd63464cdecec2dec332dfc2f0.Carlos O'Donell2014-03-031-6/+109
| | | | | | | Objections were raised surrounding the calloc simplification and it is better to revert the patch, continue discussions and then submit a new patch for inclusion with all issues fully addressed.
* Fix fallout from Joseph's untested Makeconfig change.Roland McGrath2014-02-281-1/+1

* Consistently include Makeconfig after defining subdir.Joseph Myers2014-02-261-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 (A list of such variables, possibly out of date and incomplete, is in manual/maint.texi.)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. * argp/Makefile: Include Makeconfig immediately after defining subdir. * assert/Makefile: Likewise. * benchtests/Makefile: Likewise. * catgets/Makefile: Likewise. * conform/Makefile: Likewise. * crypt/Makefile: Likewise. * csu/Makefile: Likewise.

* Simplify calloc implementation.Ondřej Bílka2014-02-261-109/+6
| | | | | | To make future improvements of allocator simpler we could for now calloc just call malloc and memset. With that we could omit a changes that would duplicate malloc changes anyway.
* Generate .test-result files for tests with special rules.Joseph Myers2014-02-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch, an updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00194.html> now proposed for inclusion in glibc, extends the generation of PASS and FAIL status in .test-result files for individual tests to cover tests with their own custom makefile rules. This is just adding $(evaluate-test) calls to all such rules, since tests with multiple commands were previously split into separate tests. Note that the tests the makefiles expect to fail (posix/annexc and conformtest) currently get FAIL listed in the .test-result file, rather than XFAIL; a subsequent patch will introduce a better XFAIL mechanism.

* Fix race in free() of fastbin chunk: BZ #15073Maxim Kuvyrkov2013-12-241-8/+12
| | | | | | | | | | | | Perform sanity check only if we have_lock. Due to lockless nature of fastbins we need to be careful derefencing pointers to fastbin entries (chunksize(old) in this case) in multithreaded environments. The fix is to add have_lock to the if-condition checks. The rest of the patch only makes code more readable. * malloc/malloc.c (_int_free): Perform sanity check only if we have_lock.

* Use __glibc_block in public headers.Meador Inge2013-11-211-1/+1
| | | | | | | | | | | | As detailed in PR11157, the use of '__block' is known to interfere with keywords in some environments, such as the Clang -fblocks extension. Recently a similar issue was raised concerning the use of '__unused' and a '__glibc' prefix was proposed to create a glibc implementation namespace for these sorts of issues [1]. This patches takes that approach. [1] https://sourceware.org/ml/libc-alpha/2012-02/msg00047.html [2] http://lists.debian.org/debian-glibc/2013/11/msg00020.html
