2016-12-09support: Introduce new subdirectory for test infrastructureFlorian Weimer1-705/+46
The new test driver in <support/test-driver.c> has feature parity with the old one. The main difference is that its hooking mechanism is based on functions and function pointers instead of macros. This commit also implements a new environment variable, TEST_COREDUMPS, which disables the code which disables coredumps (that is, it enables them if the invocation environment has not disabled them). <test-skeleton.c> defines wrapper functions so that it is possible to use existing macros with the new-style hook functionality. This commit changes only a few test cases to the new test driver, to make sure that it works as expected.
2016-11-27Minor problems exposed by compiling C++ tests under _ISOMAC.Zack Weinberg1-0/+1
* libio/libio.h: Use __USE_GNU, not _GNU_SOURCE, in a conditional. * test-skeleton.c: Include stdint.h to ensure uintptr_t is available.

2016-10-07Consolidate fallocate{64} implementationsAdhemerval Zanella1-0/+19
This patch consolidates all the fallocate{64} implementation for Linux in only one (sysdeps/unix/sysv/linux/fallocate{64}.c). It also removes the syscall from the auto-generation using assembly macros. The new macro SYSCALL_LL{64} is used to handle the offset argument. Checked on x86_64, x32, i386, aarch64, and ppc64le. * sysdeps/unix/sysv/linux/Makefile (test): Add tst-fallocate and tst-fallocate64. * sysdeps/unix/sysv/linux/tst-fallocate.c: New file. * sysdeps/unix/sysv/linux/tst-fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/tst-fallocate-common.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/fallocate.c: Remove file. * sysdeps/unix/sysv/linux/mips/mips64/n32/fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/fallocate.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/fallocate.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/fallocate.c (fallocate): Use SYSCALL_LL macro on offset argument. * sysdeps/unix/sysv/linux/fallocate64.c (fallocate64): Use SYSCALL_LL64 on offset argument. * test-skeleton.c (FAIL_RET): Add macro. (FAIL_EXIT): Likewise. (FAIL_EXIT1): Likewise. (_FAIL): Likewise.
2016-09-23test-skeleton.c: Remove unintended #include <stdarg.h>.Florian Weimer1-1/+0
2016-09-21Add test case for O_TMPFILE handling in open, openatFlorian Weimer1-0/+15
Also put xasprintf into test-skeleton.c (written in such a way that including <stdarg.h> is not needed).
2016-08-26Fix test-skeleton C99 designed initializationAdhemerval Zanella1-1/+1
ISO C forbids empty initializer braces (6.7.9 initializer-list must contain at least one initializer). However GCC allows it, generating a warning depending of the version. With GCC 4.8 on ARM I noticed tst-initializers1.c fails to build with: In file included from tst-initializers1.c:60:0: ../test-skeleton.c: In function 'delayed_exit_thread': ../test-skeleton.c:687:10: error: missing initializer for field 'tv_sec' of 'struct timespec' [-Werror=missing-field-initializers] struct timespec remaining = {} While with GCC 5.1 the same warning is just spilled with -pedantic. To be safe this patch just zero initialize the struct as expected. Tested on armhf. * test-skeleton.c (delayed_exit_thread): Add initializer on struct timespec C99 designated initialization.
2016-08-26nptl: Avoid expected SIGALRM in most tests [BZ #20432]Florian Weimer1-0/+157
Before this change, several tests did not detect early deadlocks because they used SIGALRM as the expected signal, and they ran for the full default TIMEOUT seconds. This commit adds a new delayed_exit function to the test skeleton, along with several error-checking wrappers to pthread functions. Additional error checking is introduced into several tests.
2016-08-02malloc: Run tests without calling mallopt [BZ #19469]Florian Weimer1-0/+2
The compiled tests no longer refer to the mallopt symbol from their main functions. (Some tests still call mallopt explicitly, which is fine.)
2016-06-23test-skeleton.c (xrealloc): Support realloc-as-freeFlorian Weimer1-3/+3
If the requested size is zero, realloc returns NULL, but the deallocation is still successful, unless the pointer is also NULL, when realloc behaves as malloc (0).
2016-06-23test-skeleton.c: xmalloc, xcalloc, xrealloc are potentially unusedFlorian Weimer1-3/+3
__attribute__ ((used)) means that the function has to be emitted in assembly because it is referenced in ways the compiler cannot detect (such as asm statements, or some post-processing on the generated assembly). The unused attribute needs to come first, otherwise it is applied to the return type and not the function definition.
2016-06-23test-skeleton.c: Add write_message functionFlorian Weimer1-0/+10
2016-06-082016-06-09 Paul Pluzhnikov <ppluzhnikov@gmail.com>Paul Pluzhnikov1-9/+49
* test-skeleton.c (oom_error, xmalloc, xcalloc, xrealloc): New functions. (add_temp_file): Use them.
2016-03-07test-skeleton.c: Do not set RLIMIT_DATA [BZ #19648]Florian Weimer1-17/+0
With older kernels, it is mostly ineffective because it causes malloc to switch from sbrk to mmap (potentially invalidating malloc testing compared to what real appliations do). With newer kernels which have switched to enforcing RLIMIT_DATA for mmap as well, some test cases will fail in an unintended fashion because the limit which was set previously does not include room for all mmap mappings.
2016-02-19test-skeleton: increase default TIMEOUT to 20 secondsMike Frysinger1-2/+3
The vast majority of timeouts I've seen w/glibc tests are due to: - slow system (e.g. <1 GHz cpu) - loaded system (e.g. lots of parallelism) Even then, I've seen timeouts on system I don't generally consider slow, or even loaded, and considering TIMEOUT is set to <=10 in ~60 tests (and <=20 in ~75 tests), it seems I'm not alone. I've just gotten in the habit of doing `export TIMEOUTFACTOR=10` on all my setups. In the edge case where there is a bug in the test and the timeout is hit, I think we all agree that's either a problem with the test or a real bug in the library somewhere. In either case, the incident rate should be low, so catering to that seems like the wrong trade-off. Other developers too usually set large timeout factors. Increase the default to 20 seconds to match reality.

2015-08-05test-skeleton: add usage informationMike Frysinger1-0/+36
I keep trying to run tests with --help and then remembering that does nothing when it throws an error. That means I have to dig into the source when I want to refer to flags or env vars and re-read a good amount of code to find the nested locations. Make this all much more user friendly with a usage screen that gets printed out whenever an unknown option is specified.
2015-06-05Avoid outputting to TTY after an expected memory corruption in testcaseTulio Magno Quites Machado Filho1-11/+17
Protect TTY against an expected memory corruption from testcase tst-malloc-backtrace, which is expected to SIGABRT after a forced memory corruption.
2015-05-18Ensure `wint_t' is defined before use in include/stdio.hArjun Shankar1-1/+2
While trying to get nptl/tst-initializers1.c to include the test skeleton, I came across a couple of speed bumps. Firstly: after making the appropriate changes to the test, running `make check' led to this error: > In file included from ../malloc/malloc.h:24:0, .. > from tst-initializers1.c:60: > ../include/stdio.h:111:1: error: unknown type name `wint_t' > extern wint_t __getwc_unlocked (FILE *__fp); So, `wint_t' is used before being defined. Question: Why did test-skeleton.c not cause this error in any of the other tests that include it? Anyway, I noticed include/stdio.h includes stddef.h, which in turn defines `wint_t', but only if `__need_wint_t' is defined. So I put in a `#define __need_wint_t' before the include to get rid of the error. Is that the correct fix? A subsequent `make && make check' led to this second error: > from tst-initializers1-c89.c:1: > ../test-skeleton.c: In function `main': > ../test-skeleton.c:356:11: error: `for' loop initial declarations are only > allowed in C99 mode > for (struct temp_name_list *n = temp_name_list; Although there seem to be several other C89 no-noes in test-skeleton.c, I needed only to fix this specific one for gcc-4.8.3 to stop complaining.
2015-04-27test-skeleton: Support temporary files without memory leaks [BZ#18333]Florian Weimer1-5/+18
add_temp_file now makes a copy which is freed by delete_temp_files. Callers to create_temp_file can now free the returned file name to avoid the memory leak. These changes do not affect the leak behavior of existing code. Also address a NULL pointer derefence in tzset after a memoru allocation failure, found during testing.

2014-11-12Fix tst-strcoll-overflow returning before timeout (BZ #17506)Leonhard Holz1-28/+35
Modifies the test examination in test-skeleton.c so that a test can be successful if it is interrupted or it returns uninterrupted with the expected status. For this both EXPECTED_SIGNAL and EXPECTED_STATUS have to be set, as is done in tst-strcoll-overflow.c.
2014-06-30test-skeleton: Kill any child process's offspringMaciej W. Rozycki1-2/+7
This makes sure any subprocesses created by the program being tested get killed as well if their parent times out. Otherwise if they are really stuck, they may remain there running forever after the test case and then the whole test suite has completed, until killed by hand. * test-skeleton.c (signal_handler): Kill the whole process group before killing the child individually. (main): Report any failure on `setpgid'.
2014-06-23test-skeleton.c: Use stdout for error messagesWill Newton1-23/+21
At the moment the test skeleton uses a mixture of stdout and stderr for error message output. Using stdout for all test output keeps all output correctly ordered and properly redirected to the output file. The suggestion to use stdout is also made on the wiki: https://sourceware.org/glibc/wiki/Testing/Testsuite#Writing_a_test_case ChangeLog: 2014-06-23 Will Newton <will.newton@linaro.org> * test-skeleton.c (signal_handler): Use printf and %m rather than perror. Use printf rather than fprintf to stderr. Use puts rather than fputs to stderr. (main): Likewise.
2014-02-08tests: unify fortification handler logicMike Frysinger1-0/+28
We have multiple tests that copy & paste the same logic for disabling the fortification output. Let's unify this in the test-skeleton instead. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
