2017-09-08Sync scratch_buffer with gnulibAdhemerval Zanella
This patch syncs the scratch_buffer grom gnulib commit 3866ef6 with GLIBC code. Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures. * include/scratch_buffer.h (scratch_buffer): Use a C99 align method instead of GCC extension. * malloc/scratch_buffer_grow.c [!_LIBC]: Include libc-config.h. * malloc/scratch_buffer_grow_preserve.c [!_LIBC]: Likewise. * malloc/scratch_buffer_set_array_size.c [!_LIBC]: Likewise.
2017-09-08posix: Allow glob to match dangling symlinks [BZ #866]Adhemerval Zanella
This patch makes glob match dangling symlinks. Compared to other glob implementation (*BSD, bash, musl, and other shells as well), GLIBC seems the be the only one that does not match dangling symlinks. As for comment #5 in BZ #866, POSIX does not have any strict specification for dangling symlinks match and it is reasonable that trying to glob everything in a path should return all types of files (such as for a 'rm *'). Also, comment #7 shows even more example where GLIBC current behavior is unexepected. I avoided adding another GNU specific flag to set this behavior and instead make it the default. Although this change the semanthic from previous implementation, I think adding another compat symbol to be really unecessary as from aforementioned reasons (current behavior not defined in any standard, general idea of different implementation is to list dangling symbols). This also sync glob with gnulib commit fd1daf4 (glob: match dangling symlinks). Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures. [BZ #866] [BZ #1062] * posix/Makefile (tests): Remove bug-glob1 and tst-glob_symlinks. * posix/bug-glob1.c: Remove file. * posix/tst-glob_symlinks.c: New file. * posix/glob.c (__lstat64): New macro.

2017-09-08posix: accept inode 0 is a valid inode number (BZ #19971)Adhemerval Zanella
According to this kernel commit 2adc376c55194, d_ino 0 is a regular inode number on Linux (which also matches POSIX, as it does not treat the value as special). This patch makes glob accept is a valid inode number. This is also a sync with gnulib commit c8e57c1. Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures. [BZ #1062] [BZ #19971] * posix/glob.c (struct readdir_result): Remove skip_entry member. (readdir_result_skip_entry, D_INO_TO_RESULT): Remove. All uses removed.
2017-09-08posix: Sync glob with gnulib [BZ #1062]Adhemerval Zanella
This patch syncs posix/glob.c implementation with gnulib version b5ec983 (glob: simplify symlink detection). The only difference to gnulib code is * DT_UNKNOWN, DT_DIR, and DT_LNK definition in the case there were not already defined. Gnulib code which uses HAVE_STRUCT_DIRENT_D_TYPE will redefine them wrongly because GLIBC does not define HAVE_STRUCT_DIRENT_D_TYPE. Instead the patch check for each definition instead. Also, the patch requires additional globfree and globfree64 files for compatibility version on some architectures. Also the code simplification leads to not macro simplification (not need for NO_GLOB_PATTERN_P anymore). Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures.

2017-09-05Prefer new libm function wrappers for !LIBM_SVID_COMPAT.Joseph Myers
The initial obsoletion of SVID libm error handling left the old wrappers and __kernel_standard still being used for new ports and static linking, just with macro definitions of _LIB_VERSION and matherr that meant symbols with those names were never actually used and the code for different error handling variants could be optimized out. This patch cleans things up further by eliminating the __kernel_standard use for new ports and static linking. Now, the old wrappers no longer generate any code in the !LIBM_SVID_COMPAT case, while the new errno-only wrappers that were added for float128 support are now also used for float, double and long double in that case. The changes are generally straightforward. The w_scalb*_compat wrappers continue to be used (scalb is obsolescent in the sense of not being supported for float128, but is present in supported standards - the 2001 edition of POSIX and earlier XSI versions - so remains supported for static linking and new ports, as do the float and long double variants that are existing GNU extensions). Those wrappers would only call __kernel_standard in the _LIB_VERSION == _SVID_ case. Since we would like to be able to compile most of glibc without optimization, relying on a static function whose only use is under an if (0) condition being optimized away to avoid an undefined __kernel_standard reference may not be a good idea. Thus, the relevant code in the scalb wrappers has LIBM_SVID_COMPAT conditionals added to guarantee it's not built at all in the case where __kernel_standard does not exist. Just as i386 has its own w_sqrt_compat.c, so w_sqrt.c is also added. ia64 gets dummy w_*.c to prevent those files being built where they would conflict with the ia64 libm, as with its existing w_*_compat.c. Conditions disabling code for !LIBM_SVID_COMPAT are needed in both the math/ wrappers and in the long double wrappers in ldbl-opt (to avoid them setting up aliases and symbol versions for undefined symbols). I hope that future cleanups to how libm function aliases and symbol versioning are done will eliminate the need for most of the ldbl-opt wrappers.

2017-09-05Fix pcprofiledump cross-endian condition (bug 22086).Joseph Myers
debug/pcprofiledump.c contains code that tries to handle other-endian data. This uses a condition "(word & 0xfffffff0) == bswap_32 (0xdeb00000)". This condition is always false (the LHS always has the low four bits zero, the RHS doesn't); a correct comparison would use 0x0fffffff. This results in -Werror=tautological-compare build failures with the tile version of bits/byteswap.h and mainline GCC. https://sourceware.org/ml/libc-testresults/2017-q3/msg00400.html pcprofiledump.c: In function 'main': pcprofiledump.c:118:39: error: bitwise comparison always evaluates to false [-Werror=tautological-compare] int must_swap = (word & 0xfffffff0) == bswap_32 (0xdeb00000); ^~ This patch fixes the condition. Tested for x86_64, and with build-many-glibcs.py that it fixes the build for tilegx-linux-gnu. (Note that I have not tested the actual pcprofiledump functionality, native or cross endian, which lacks any testsuite coverage.)

bits/math-finite.h handles exp10 if __USE_GNU. It should use the condition __GLIBC_USE (IEC_60559_FUNCS_EXT), as in bits/mathcalls.h. This patch fixes the condition. Tested for x86_64. [BZ #22082] * math/bits/math-finite.h (exp10): Redirect if [__GLIBC_USE (IEC_60559_FUNCS_EXT)], not [__USE_GNU].
2017-09-04math.h: Warn about an already-defined log macroFlorian Weimer
This is a common programming error, and the cause of the problem is not always obvious. <tgmath.h> defines a log macro, but it includes <math.h> before that, so that is compatible with the warning.

2017-09-01Obsolete pow10 functions.Joseph Myers
This patch obsoletes the pow10, pow10f and pow10l functions (makes them into compat symbols, not available for new ports or static linking). The exp10 names for these functions are standardized (in TS 18661-4) and were added in the same glibc version (2.1) as pow10 so source code can change to use them without any loss of portability. Since pow10 is deliberately not provided for _Float128, only exp10, this slightly simplifies moving to the new wrapper templates in the !LIBM_SVID_COMPAT case, by avoiding needing to arrange for pow10, pow10f and pow10l to be defined by those templates. Tested for x86_64, and with build-many-glibcs.py. * manual/math.texi (pow10): Do not document. (pow10f): Likewise. (pow10l): Likewise. * math/bits/mathcalls.h [__USE_GNU] (pow10): Do not declare. * math/bits/math-finite.h [__USE_GNU] (pow10): Likewise. * math/libm-test-exp10.inc (pow10_test): Remove.
