octave-kai/gnulib-hg: lib/gettime.c annotate

annotate lib/gettime.c @ 7897:b7a83a69ac23

* MODULES.html.sh (Support for systems lacking POSIX:2001): New module sys_time. * lib/gethrxtime.c: Include <sys/time.h>, since we can no longer assume timespec.h defines struct timeval. * lib/settime.c: Likewise. * lib/utimens.c: Likewise. * lib/gettime.c (gettime): Remove test against HAVE_GETTIMEOFDAY, since we now assume the gettimeofday module. * lib/tempname.c (__gen_tempname): Likewise. * lib/gettimeofday.h: Remove. * lib/gettimeofday.c: Include <sys/time.h> instead of "gettimeofday.h". Don't include <sys/types.h> and <stdlib.h>; shouldn't be needed. Include <time.h>, for 'time()'. (localtime_buffer_addr): Also use this workaround if TZSET_CLOBBERS_LOCALTIME. Set to a dummy static variable by default, to simplify the uses. All uses changed. (localtime, gmtime, tzset, gettimeofday): Reformat slightly so that #undef is inside {}, and 'const' follows type name consistently. (tzset): Define replacement only if TZSET_CLOBBERS_LOCALTIME. (gettimeofday): Do not use the maximum possible value for tv->tv_usec, since that might break usages other than ls.c. Instead, we'll leave ls.c alone. This undoes today's patch by Bruno. Add a compile-time warning for 1s-clock resolution; we've never observed the problem but might as well keep the canary. * lib/nanosleep.c: Include timespec.h first, for interface check. * lib/nanosleep.c: Include <sys/time.h> unconditionally, since we now assume the sys_time module. * lib/tempname.c: Likewise. * lib/timespec.h: Likewise. * lib/nanosleep.c: Don't worry about TIME_WITH_SYS_TIME; no longer needed. * lib/strftime.c: Likewise. * lib/timespec.h: Likewise. * lib/posixtm.c: Include posixtm.h first, for interface check. Don't worry about TM_IN_SYS_TIME; that's wayyy obsolete. * lib/posixtm.h: Include stdbool.h and time.h, for proper interface. * lib/strftime.c: Don't include <sys/types.h>; shouldn't be needed. * lib/sys_time_.h: New file. * lib/timespec.h (struct timespec): Use long int, not long. * m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY): (gl_FUNC_GETTIMEOFDAY_CLOBBER, gl_PREREQ_GETTIMEOFDAY): Remove obsolescent call to AC_HEADER_TIME. * m4/mktime.m4 (AC_FUNC_MKTIME): Likewise. * m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Likewise. * m4/strftime.m4 (gl_FUNC_STRFTIME): Likewise. * m4/timespec.m4 (gl_TIMESPEC, gl_CHECK_TYPE_STRUCT_TIMESPEC): Likewise. * m4/tzset.m4 (gl_FUNC_TZSET_CLOBBER): Likewise. * m4/utimbuf.m4 (gl_CHECK_TYPE_STRUCT_UTIMBUF): Likewise. * m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY): Move sys/time.h tests into the sys_time module. Check for gettimeofday just once. Prefix our variables with gl_, not with ac_ or jm_. Tighten test for gettimeofday signature to just check the signature. Merely compile it, since linking doesn't test signature. Improve test for whether gettimeofday.o is actually needed. (gl_FUNC_GETTIMEOFDAY_CLOBBER): Renamed from AC_FUNC_GETTIMEOFDAY_CLOBBER. All uses changed. Use AC_RUN_IFELSE rather than AC_TRY_RUN. If clobbering, set and define GETTIMEOFDAY_CLOBBERS_LOCALTIME. (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): Don't define GETTIMEOFDAY_CLOBBERS_LOCALTIME; that's gl_FUNC_GETTIMEOFDAY_CLOBBER's job. Don't define tzset; that's gl_FUNC_TZSET_CLOBBER's job. * m4/mktime.m4 (AC_FUNC_MKTIME): Just include <time.h> rather than worrying about sys/time.h. * m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Don't bother worrying about TIME_WITH_SYS_TIME. * m4/stat-time.m4 (gl_STAT_TIME): Likewise. * m4/posixtm.m4 (gl_POSIXTM): Remove obsolescent call to AC_STRUCT_TM. * m4/sys_time_h.m4: New file. * m4/tzset.m4 (gl_FUNC_TZSET_CLOBBER): Require gl_HEADER_SYS_TIME_H. Don't include sys/time.h. Return from main rather than exiting. Define TZSET_CLOBBERS_LOCALTIME, for consistency with other names; all uses changed. * modules/gethrxtime (Depends-on): Add sys_time. * modules/gettime (Depends-on): Likewise. * modules/gettimeofday (Depends-on): Likewise. * modules/nanosleep (Depends-on): Likewise. * modules/settime (Depends-on): Likewise. * modules/tempname (Depends-on): Likewise. * modules/utimens (Depends-on): Likewise. * modules/gettimeofday (Files): Remove lib/gettimeofday.h. (Include:) Change back to <sys/time.h>. (Maintainer:) Add self. * modules/sys_time: New file. * modules/tempname (Depends-on): Add gettimeofday. * tests/test-gettimeofday.c: Include <sys/time.h> rather than gettimeofday.h.
