* timespec: fix resolution confusionPaul Eggert2018-09-1013-44/+62
| | | | | | | | | | | In normal usage, clock resolution is given in seconds, but the code was mistakenly using inverse seconds and calling it “resolution”. Fix this, partly by renaming two identifiers. The old names will be kept for a bit, to ease transition. * lib/timespec.h (TIMESPEC_HZ, LOG10_TIMESPEC_HZ): New constants, replacing TIMESPEC_RESOLUTION and LOG10_TIMESPEC_RESOLUTION, which are now obsolescent. All uses changed.
* mktime: simplify in prep for glibc mergePaul Eggert2018-09-093-10/+9
| | | | | | * lib/mktime.c, lib/timegm.c [_LIBC]: Include mktime-internal.h (a small file just for glibc) instead of using a typedef.
* intprops: minor clarification of codePaul Eggert2018-09-072-2/+8
| | | | | * lib/intprops.h (_GL_BINARY_OP_OVERFLOW): Use _GL_INT_CONVERT rather than reinventing it.

* mktime: fix unlikely race+overflow bugPaul Eggert2018-09-022-1/+11
| | | | | | | | Problem reported by Alexandre Oliva in: https://sourceware.org/bugzilla/show_bug.cgi?id=16346 * lib/mktime.c (__mktime_internal): Access *OFFSET only once, to avoid an unlikely race if the compiler delays a load and if this cascades into a signed integer overflow.
* mktime, timegm: simplify glibc time64_tPaul Eggert2018-09-013-2/+10
| | | | | | | | | * lib/mktime.c, lib/timegm.c (mktime_offset_t) [_LIBC]: Now long int, not time_t, since long int is the longstanding type for this in glibc and there is no need to change it even if time_t becomes 64 bits - even int would do, though this would be a change to the glibc generated code. When this change is merged into glibc, it should simplify the time_t vs time64_t situation.
* mktime, timegm: simplify merge to glibcPaul Eggert2018-09-014-74/+109
| | | | | | | | | | | | | | | | | | | | Move code around to make a merge to glibc easier to audit. This should not change behavior. * lib/mktime.c: Include more standard files unconditionally. (NEED_MKTIME_INTERNAL, NEED_MKTIME_WINDOWS) (NEED_MKTIME_WORKING): Give default values to pacify -Wundef, which glibc uses. Default NEED_MKTIME_WORKING to DEBUG_MKTIME, to simplify later conditionals; default the others to zero. In uses of these conditionals, explicitly spell out how _LIBC affects things, so it’s easier to review from a glibc viewpoint. (my_tzset, __tzset) [!_LIBC]: New function and macro, to better compartmentalize tzset issues. Move system-dependent tzsettish code here from mktime. (mktime): Move tzsettish code to my_tzset, and move localtime_offset to within mktime so that it doesn’t need a separate ifdef. * lib/mktime-internal.h (__gmtime_r, __localtime_r, __mktime_internal): Move these macros here from lib/mktime.c and lib/gmtime.c.

* intprops: avoid evaluation of some expressionsPaul Eggert2018-08-272-7/+19
| | | | | | | | | This makes EXPR_SIGNED (e) easier to use, as it no longer evaluates the expression E. Formerly, E was required to be free of side effects. * lib/intprops.h (_GL_INT_CONVERT, _GL_INT_NEGATE_CONVERT) (EXPR_SIGNED, TYPE_WIDTH, _GL_INT_MINIMUM, _GL_INT_MAXIMUM) (_GL_SIGNED_INT_MAXIMUM): Do not evaluate the expression arg.
