2018-12-05Y2038: make __tz_convert compatible with 64-bit-timeAlbert ARIBAUD (3ADEV)
Now that __time64_t exists, we can switch internal function __tz_convert from 32-bit to 64-bit time. This involves switching some other internal functions as well, namely __tz_compute and __offtime. Tested with 'make check' on x86_64-linux-gnu and i686-linux.gnu. * include/time.h (__tz_compute): Replace time_t with __time64_t. (__tz_convert): Replace time_t* with __time64_t. (__offtime): Replace time_t* with __time64_t. * time/gmtime.c (__gmtime_r): Adjust call to __tz_convert. (gmtime): Likewise. * time/localtime.c (__localtime_r): Likewise. (localtime): Likewise. * time/offtime.c: Replace time_t with __time64_t. * time/tzset.c: Likewise.
2018-10-24Y2038: Add 64-bit time for all architecturesAlbert ARIBAUD (3ADEV)
glibc support for 64-bit time_t on 32-bit architectures will involve: - Using 64-bit times inside glibc, with conversions to and from 32-bit times taking place as necessary for interfaces using such times. - Adding 64-bit-time support in the glibc public API. This support should be dynamic, i.e. glibc should provide both 32-bit and 64-bit implementations and let user code choose at compile time whether to use the 32-bit or 64-bit interfaces. This requires a glibc-internal name for a type for times that are always 64-bit. Based on __TIMESIZE, a new macro is defined, __TIME64_T_TYPE, which is always the right __*_T_TYPE to hold a 64-bit-time. __TIME64_T_TYPE equals __TIME_T_TYPE if __TIMESIZE equals 64 and equals __SQUAD_T_TYPE otherwise. __time64_t can then replace uses of internal_time_t. This patch was tested by running 'make check' on branch master then applying this patch and its predecessor and running 'make check' again, and checking that both 'make check' yield identical results. This was done on x86_64-linux-gnu and i686-linux-gnu. * bits/time64.h: New file. * include/time.h: Replace internal_time_t with __time64_t. * posix/bits/types (__time64_t): Add. * stdlib/Makefile: Add bits/time64.h to includes. * time/tzfile.c: Replace internal_time_t with __time64_t.
2018-09-19Fix mktime localtime offset confusionPaul Eggert
[BZ #23603] * include/time.h (__mktime_internal): The localtime offset is now of type long int instead of time_t. This is the longstanding type in glibc, and it is more than enough to represent difference between localtime and gmtime even if it is 32 bits and time_t is 64. Changing it now will let us avoid an unnecessary change when time_t is widened to 64 bits on 32-bit platforms. * time/mktime-internal.h (mktime_offset_t): Now long int.

This patch adds internal definition (through {libc_}hidden_{proto,def}) and also change some strong to weak alias for symbols that might be used by C11 threads implementations. The patchset should not change libc/libpthread functional, although object changes are expected (since now internal symbols are used instead) and final exported symbols through GLIBC_PRIVATE is also expanded (to cover libpthread usage of __mmap{64}, __munmap, __mprotect).

2017-06-20Use locale_t, not __locale_t, throughout glibcZack Weinberg
<locale.h> is specified to define locale_t in POSIX.1-2008, and so are all of the headers that define functions that take locale_t arguments. Under _GNU_SOURCE, the additional headers that define such functions have also always defined locale_t. Therefore, there is no need to use __locale_t in public function prototypes, nor in any internal code. * ctype/ctype-c99_l.c, ctype/ctype.h, ctype/ctype_l.c * include/monetary.h, include/stdlib.h, include/time.h * include/wchar.h, locale/duplocale.c, locale/freelocale.c * locale/global-locale.c, locale/langinfo.h, locale/locale.h * locale/localeinfo.h, locale/newlocale.c * locale/nl_langinfo_l.c, locale/uselocale.c * localedata/bug-usesetlocale.c, localedata/tst-xlocale2.c * stdio-common/vfscanf.c, stdlib/monetary.h, stdlib/stdlib.h * stdlib/strfmon_l.c, stdlib/strtod_l.c, stdlib/strtof_l.c * stdlib/strtol.c, stdlib/strtol_l.c, stdlib/strtold_l.c * stdlib/strtoll_l.c, stdlib/strtoul_l.c, stdlib/strtoull_l.c * string/strcasecmp.c, string/strcoll_l.c, string/string.h * string/strings.h, string/strncase.c, string/strxfrm_l.c * sysdeps/ieee754/float128/strtof128_l.c * sysdeps/ieee754/float128/wcstof128.c * sysdeps/ieee754/float128/wcstof128_l.c * sysdeps/ieee754/ldbl-128ibm/strtold_l.c * sysdeps/ieee754/ldbl-64-128/strtold_l.c * sysdeps/ieee754/ldbl-opt/nldbl-compat.c * sysdeps/ieee754/ldbl-opt/nldbl-strfmon_l.c * sysdeps/ieee754/ldbl-opt/nldbl-strtold_l.c * sysdeps/ieee754/ldbl-opt/nldbl-wcstold_l.c * sysdeps/powerpc/powerpc32/power7/strcasecmp.S * sysdeps/powerpc/powerpc64/power7/strcasecmp.S * sysdeps/x86_64/strcasecmp_l-nonascii.c * sysdeps/x86_64/strncase_l-nonascii.c, time/strftime_l.c * time/strptime_l.c, time/time.h, wcsmbs/mbsrtowcs_l.c * wcsmbs/wchar.h, wcsmbs/wcscasecmp.c, wcsmbs/wcsncase.c * wcsmbs/wcstod.c, wcsmbs/wcstod_l.c, wcsmbs/wcstof.c * wcsmbs/wcstof_l.c, wcsmbs/wcstol_l.c, wcsmbs/wcstold.c * wcsmbs/wcstold_l.c, wcsmbs/wcstoll_l.c, wcsmbs/wcstoul_l.c * wcsmbs/wcstoull_l.c, wctype/iswctype_l.c * wctype/towctrans_l.c, wctype/wcfuncs_l.c * wctype/wctrans_l.c, wctype/wctype.h, wctype/wctype_l.c: Change all uses of __locale_t to locale_t.
2017-06-20Rename xlocale.h to bits/types/__locale_t.h.Zack Weinberg
xlocale.h is already a single-type micro-header, defining struct __locale_struct and the typedefs __locale_t and locale_t. This patch brings it into the bits/types/ scheme: there are now bits/types/__locale_t.h which defines only __locale_struct and __locale_t, and bits/types/locale_t.h which defines locale_t as well as the other two. None of *our* headers need __locale_t.h, but it appears to me that libstdc++ could make use of it. There are a lot of external uses of xlocale.h, but all the uses I checked had an autoconf test or equivalent for its existence. It has never been available from other C libraries, and it has always contained a comment reading "This file is not standardized, don't rely on it, it can go away without warning" so I think dropping it is pretty safe. I also took the opportunity to clean up comments in various public header files that still talk about the *_l interfaces as though they were completely nonstandard. There are a few of them, notably the strtoX_l and wcstoX_l families, that haven't been standardized, but the bulk are in POSIX.1-2008. * locale/xlocale.h: Rename to... * locale/bits/types/__locale_t.h: ...here. Adjust commentary. Only define struct __locale_struct and __locale_t, not locale_t. * locale/bits/types/locale_t.h: New file; define locale_t here. * locale/Makefile (headers): Update to match. * include/xlocale.h: Delete wrapper. * include/bits/types/__locale_t.h: New wrapper. * include/bits/types/locale_t.h: New wrapper. * ctype/ctype.h, include/printf.h, include/time.h * locale/langinfo.h, locale/locale.h, stdlib/monetary.h * stdlib/stdlib.h, string/string.h, string/strings.h, time/time.h * wcsmbs/wchar.h, wctype/wctype.h: Use bits/types/locale_t.h. Correct outdated comments regarding the standardization status of the functions that take locale_t arguments. * stdlib/strtod_l.c, stdlib/strtof_l.c, stdlib/strtol_l.c * stdlib/strtold_l.c, stdlib/strtoul_l.c, stdlib/strtoull_l.c * sysdeps/ieee754/ldbl-128ibm/strtold_l.c * sysdeps/ieee754/ldbl-64-128/strtold_l.c * wcsmbs/wcstod.c, wcsmbs/wcstod_l.c, wcsmbs/wcstof.c * wcsmbs/wcstof_l.c, wcsmbs/wcstold.c, wcsmbs/wcstold_l.c: Don't include xlocale.h. If necessary, include locale.h instead. * stdlib/strtold_l.c: Unconditionally include wchar.h.
2017-05-11Suppress internal declarations for most of the testsuite.Zack Weinberg
This patch adds a new build module called 'testsuite'. IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus (which means several ad-hoc tests for __cplusplus can go away). libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is defined; in particular, _ISOMAC mode does not get config.h automatically anymore. There are still quite a few tests that need to see internal gunk of one variety or another. For them, we now have 'tests-internal' and 'test-internal-extras'; files in this category will still be compiled with MODULE_NAME=nonlib, and everything proceeds as it always has. The bulk of this patch is moving tests from 'tests' to 'tests-internal'. There is also 'tests-static-internal', which has the same effect on files in 'tests-static', and 'modules-names-tests', which has the *inverse* effect on files in 'modules-names' (it's inverted because most of the things in modules-names are *not* tests). For both of these, the file must appear in *both* the new variable and the old one. There is also now a special case for when libc-symbols.h is included without MODULE_NAME being defined at all. (This happens during the creation of libc-modules.h, and also when preprocessing Versions files.) When this happens, IS_IN is set to be always false and _ISOMAC is *not* defined, which was the status quo, but now it's explicit. The remaining changes to C source files in this patch seemed likely to cause problems in the absence of the main change. They should be relatively self-explanatory. In a few cases I duplicated a definition from an internal header rather than move the test to tests-internal; this was a judgement call each time and I'm happy to change those however reviewers feel is more appropriate. * Makerules: New subdir configuration variables 'tests-internal' and 'test-internal-extras'. Test files in these categories will still be compiled with MODULE_NAME=nonlib. Test files in the existing categories (tests, xtests, test-srcs, test-extras) are now compiled with MODULE_NAME=testsuite. New subdir configuration variable 'modules-names-tests'. Files which are in both 'modules-names' and 'modules-names-tests' will be compiled with MODULE_NAME=testsuite instead of MODULE_NAME=extramodules. (gen-as-const-headers): Move to tests-internal. (do-tests-clean, common-mostlyclean): Support tests-internal. * Makeconfig (built-modules): Add testsuite. * Makefile: Change libof-check-installed-headers-c and libof-check-installed-headers-cxx to 'testsuite'. * Rules: Likewise. Support tests-internal. * benchtests/strcoll-inputs/filelist#en_US.UTF-8: Remove extra-modules.mk. * config.h.in: Don't check for __OPTIMIZE__ or __FAST_MATH__ here. * include/libc-symbols.h: Move definitions of _GNU_SOURCE, PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the very top of the file and rationalize their order. If MODULE_NAME is not defined at all, define IS_IN to always be false, and don't define _ISOMAC. If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are true, define _ISOMAC and suppress everything else in this file, starting with the inclusion of config.h. Do check for inappropriate definitions of __OPTIMIZE__ and __FAST_MATH__ here, but only if _ISOMAC is not defined. Correct some out-of-date commentary. * include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE and _Mlong_double_ before including math.h. * include/string.h: If _ISOMAC is defined, don't expose _STRING_ARCH_unaligned. Move a comment to a more appropriate location. * include/errno.h, include/stdio.h, include/stdlib.h, include/string.h * include/time.h, include/unistd.h, include/wchar.h: No need to check __cplusplus nor use __BEGIN_DECLS/__END_DECLS. * misc/sys/cdefs.h (__NTHNL): New macro. * sysdeps/m68k/m680x0/fpu/bits/mathinline.h (__m81_defun): Use __NTHNL to avoid errors with GCC 6. * elf/tst-env-setuid-tunables.c: Include config.h with _LIBC defined, for HAVE_TUNABLES. * inet/tst-checks-posix.c: No need to define _ISOMAC. * intl/tst-gettext2.c: Provide own definition of N_. * math/test-signgam-finite-c99.c: No need to define _ISOMAC. * math/test-signgam-main.c: No need to define _ISOMAC. * stdlib/tst-strtod.c: Convert to test-driver.

2016-09-23Installed-header hygiene (BZ#20366): time.h types.Zack Weinberg
Many headers are expected to expose a subset of the type definitions in time.h. time.h has a whole bunch of messy logic for conditionally defining some its types and structs, but, as best I can tell, this has never worked 100%. In particular, __need_timespec is ineffective if _TIME_H has already been defined, which means that if you compile #include <time.h> #include <sched.h> with e.g. -fsyntax-only -std=c89 -Wall -Wsystem-headers, you will get In file included from test.c:2:0: /usr/include/sched.h:74:57: warning: "struct timespec" declared inside parameter list will not be visible outside of this definition or declaration extern int sched_rr_get_interval (__pid_t __pid, struct timespec *__t) __THROW; ^~~~~~~~ And if you want to _use_ sched_rr_get_interval in a TU compiled that way, you're hosed.

2013-06-11Fix symbol definitions for __clock_* functionsSiddhesh Poyarekar
__clock_gettime and other __clock_* functions could result in an extra PLT reference within libc.so if it actually gets used. None of the code currently uses them, which is why this probably went unnoticed.
