2015-05-21Add sprintf benchmark.Carlos O'Donell4-1/+26
Tests position and non-positional arguments with two test string.
2015-05-21Simplify handling of nameserver configuration in resolverAndreas Schwab4-137/+105
Remove use of ext.nsmap member of struct __res_state and always use an identity mapping betwen the nsaddr_list array and the ext.nsaddrs array. The fact that a nameserver has an IPv6 address is signalled by setting nsaddr_list[].sin_family to zero.
2015-05-20conformtest: use proper _POSIX_C_SOURCE value for POSIX.Joseph Myers2-1/+4
The conform/ tests were using -D_POSIX_C_SOURCE=199912 to test "POSIX" (1995/6). This patch changes them to use 199506L, the proper value from the relevant edition of POSIX. (This doesn't make any difference to features.h, but is the logically correct value to use.) Tested for x86_64. * conform/GlibcConform.pm ($CFLAGS{"POSIX"}): Use -D_POSIX_C_SOURCE=199506L.
2015-05-20conformtest: correct POSIX expectations for locale.h.Joseph Myers2-1/+3
When cleaning up conformtest expectations for POSIX for locale.h in <https://sourceware.org/ml/libc-alpha/2012-11/msg00382.html>, I missed that locale.h had contents defined in POSIX.2:1993 as well as POSIX.1:1995/6. Thus, LC_MESSAGES *should* in fact be required for POSIX, because POSIX.2 says so; this patch adds that expectation back. Tested for x86_64. * conform/data/locale.h-data [POSIX] (LC_MESSAGES): Require.

2015-05-19Fix ldbl-96 remquol (finite, Inf) (bug 18244).Joseph Myers4-3/+46
ldbl-96 remquol wrongly handles the case where the first argument is finite and the second infinite, because the check for the second argument being a NaN fails to disregard the explicit high mantissa bit and so wrongly interprets an infinity as being a NaN. This patch fixes this by masking off that bit, and improves test coverage for both remainder and remquo (various cases were missing tests, or, as in the case of the bug, were tested only for one of the two functions). Tested for x86_64 and x86. [BZ #18244] * sysdeps/ieee754/ldbl-96/s_remquol.c (__remquol): Ignore explicit high mantissa bit when testing whether P is a NaN. * math/libm-test.inc (remainder_test_data): Add more tests.

2015-05-19Fix i386 atanhl spurious underflows (bug 18049).Joseph Myers5-4/+352
The i386 implementation of atanhl, for small arguments, does a calculation that involves computing twice the square of the argument, resulting in spurious underflows for some arguments. This patch fixes this by just returning the argument when its exponent is below -32, with underflow being forced as needed for subnormal arguments. Tested for x86 and x86_64. [BZ #18049] * sysdeps/i386/fpu/e_atanhl.S (__ieee754_atanhl): For exponents below -32, return the argument, with underflow if subnormal. * math/auto-libm-test-in: Add more tests of atanh. * math/auto-libm-test-out: Regenerated.

2015-05-19Avoid deadlock in malloc on backtrace (BZ #16159)Siddhesh Poyarekar7-86/+226
When the malloc subsystem detects some kind of memory corruption, depending on the configuration it prints the error, a backtrace, a memory map and then aborts the process. In this process, the backtrace() call may result in a call to malloc, resulting in various kinds of problematic behavior. In one case, the malloc it calls may detect a corruption and call backtrace again, and a stack overflow may result due to the infinite recursion. In another case, the malloc it calls may deadlock on an arena lock with the malloc (or free, realloc, etc.) that detected the corruption. In yet another case, if the program is linked with pthreads, backtrace may do a pthread_once initialization, which deadlocks on itself. In all these cases, the program exit is not as intended. This is avoidable by marking the arena that malloc detected a corruption on, as unusable. The following patch does that. Features of this patch are as follows: - A flag is added to the mstate struct of the arena to indicate if the arena is corrupt. - The flag is checked whenever malloc functions try to get a lock on an arena. If the arena is unusable, a NULL is returned, causing the malloc to use mmap or try the next arena. - malloc_printerr sets the corrupt flag on the arena when it detects a corruption - free does not concern itself with the flag at all. It is not important since the backtrace workflow does not need free. A free in a parallel thread may cause another corruption, but that's not new - The flag check and set are not atomic and may race. This is fine since we don't care about contention during the flag check. We want to make sure that the malloc call in the backtrace does not trip on itself and all that action happens in the same thread and not across threads. I verified that the test case does not show any regressions due to this patch. I also ran the malloc benchmarks and found an insignificant difference in timings (< 2%). * malloc/Makefile (tests): New test case tst-malloc-backtrace. * malloc/arena.c (arena_lock): Check if arena is corrupt. (reused_arena): Find a non-corrupt arena. (heap_trim): Pass arena to unlink. * malloc/hooks.c (malloc_check_get_size): Pass arena to malloc_printerr. (top_check): Likewise. (free_check): Likewise.

2015-05-19Succeed if make check does not report any errorsSiddhesh Poyarekar2-1/+3
The conditional that evaluates if there are any FAILed test cases currently always fails, since we ensure it fails if we find any unexpected results in tests.sum and it would obviously fail if it does not find failed results in tests.sum. This patch fixes this by simply inverting the result of the egrep, i.e. succeed if egrep fails (to find failed results) and fail if it succeeds. Tested with 'make subdirs=localedata check' and 'make subdirs=locale check' where all tests succeed and with 'make subdirs=elf check' where a couple of tests fail for me. * Makefile (summarize-tests): Fix return value on success.
2015-05-19Add envz_remove to the libc manualSiddhesh Poyarekar2-0/+12
I was told that Ma Shimao submitted a patch to add envz_remove to the libc manual, but the patch could not be accepted since he does not have a copyright assignment in place. I have been woefully behind on libc-alpha recently and have not seen the patch or the discussion thread. I have also not read the man page for envz_remove, so Alexandre Oliva asked me if I could write this independently and post a patch. The patch below is the result of the same - I have written it based on the implementation in string/envz.c and Alex told me via email that the function is AS, AC and MT-safe like envz_strip. I assume Alex and Carlos cannot review this since they have been tainted by the original patch (I haven't even tried to look for a link to it since I don't want to be tainted) so someone else will have to review this. If there are no reviewers till the end of the week, I will commit this since I believe there is a chance that there are no other reviewers who haven't read that thread. * manual/string.texi (Envz Functions): Add envz_remove.

2015-05-18Ensure `wint_t' is defined before use in include/stdio.hArjun Shankar4-3/+14
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.

2015-05-15Fix atanhl missing underflows (bug 16352).Joseph Myers11-137/+235
Similar to various other bugs in this area, some atanh implementations do not raise the underflow exception for subnormal arguments, when the result is tiny and inexact. This patch forces the exception in a similar way to previous fixes. (No change in this regard is needed for the i386 implementation; special handling to force underflows in these cases will only be needed there when the spurious underflows, bug 18049, get fixed.)

2015-05-15Fix tanf spurious underflows (bug 18221).Joseph Myers5-2/+60
The flt-32 implementation of tanf produces spurious underflow exceptions for some small arguments, through computing values on the order of x^5. This patch fixes this by adjusting the threshold for returning x (or, as applicable, +/- 1/x) to 2**-13 (the next term in the power series being x^3/3). Tested for x86_64 and x86. [BZ #18221] * sysdeps/ieee754/flt-32/k_tanf.c (__kernel_tanf): Use 2**-13 not 2**-28 as threshold for returning x or +/- 1/x. * math/auto-libm-test-in: Add more tests of tan. * math/auto-libm-test-out: Regenerated.
2015-05-15Fix lgammaf spurious underflows (bug 18220).Joseph Myers5-4/+38
The flt-32 implementation of lgammaf produces spurious underflow exceptions for some large arguments, because of calculations involving x^-2 multiplied by small constants. This patch fixes this by adjusting the threshold for a simpler computation to 2**26 (the error in the simpler computation is on the order of 0.5 * log (x), for a result on the order of x * log (x)). Tested for x86_64 and x86. [BZ #18220] * sysdeps/ieee754/flt-32/e_lgammaf_r.c (__ieee754_lgammaf_r): Use 2**26 not 2**58 as threshold for returning x * (log (x) - 1). * math/auto-libm-test-in: Add another test of lgamma. * math/auto-libm-test-out: Regenerated.

2015-05-15Fix erfcf spurious underflows (bug 18217).Joseph Myers5-3/+63
The flt-32 implementation of erfcf produces spurious underflow exceptions for some arguments close to 0, because of calculations squaring the argument and then multiplying by small constants. This patch fixes this by adjusting the threshold for arguments for which the result is so close to 1 that 1 - x will give the right result from 2**-56 to 2**-26. (If 1 - x * 2/sqrt(pi) were used, the errors would be on the order of x^3 and a much larger threshold could be used.) Tested for x86_64 and x86. [BZ #18217] * sysdeps/ieee754/flt-32/s_erff.c (__erfcf): Use 2**-26 not 2**-56 as threshold for returning 1 - x. * math/auto-libm-test-in: Add more tests of erfc. * math/auto-libm-test-out: Regenerated.
2015-05-14Fix atanf spurious underflows (bug 18196).Joseph Myers5-3/+35
The sysdeps/ieee754/flt-32 version of atanf produces spurious underflow exceptions for some large arguments, because of computations that compute x^-4. This patch fixes this by adjusting the threshold for large arguments (for which +/- pi/2 can just be returned, the correct result being roughly +/- pi/2 - 1/x) from 2^34 to 2^25. Tested for x86_64 and x86. [BZ #18196] * sysdeps/ieee754/flt-32/s_atanf.c (__atanf): Use 2^25 not 2^34 as threshold for large arguments. * math/auto-libm-test-in: Add another test of atan. * math/auto-libm-test-out: Regenerated.
2015-05-14Fix log1p missing underflows (bug 16339).Joseph Myers9-109/+202
Similar to various other bugs in this area, some log1p implementations do not raise the underflow exception for subnormal arguments, when the result is tiny and inexact. This patch forces the exception in a similar way to previous fixes. (The ldbl-128ibm implementation doesn't currently need any change as it already generates this exception, albeit through code that would generate spurious exceptions in other cases; special code for this issue will only be needed there when fixing the spurious exceptions.)
