* mktime: avoid signed integer overflowPaul Eggert2012-05-231-4/+4
| | | | | * time/mktime.c (__mktime_internal): Do not mishandle the case where diff == INT_MIN.
* mktime: simplify computation of averagePaul Eggert2012-05-231-3/+1
| | | | | * time/mktime.c (ranged_convert): Use new time_t_avg function instead of rolling our own (probably-slower) code.
* mktime: do not assume signed right shift propagates sign bitPaul Eggert2012-05-231-6/+12
| | | | | | | * time/mktime.c (isdst_differ): New static function. (__mktime_internal): No need to normalize tm_isdst now. (__mktime_internal, not_equal_tm): Use isdst_differ to compare tm_isdst values.
* mktime: merge another wrapv change from gnulibPaul Eggert2012-05-231-1/+1
| | | | | * time/mktime.c (TYPE_MAXIMUM): Rework slightly to avoid diagnostics from some compilers.
* mktime: remove incorrect attempt at unusual arithmeticsPaul Eggert2012-05-231-9/+6
| | | | | | | | * time/mktime.c (TYPE_ONES_COMPLEMENT, TYPE_SIGNED_MAGNITUDE): Remove. The code didn't really work on such machines anyway. (TYPE_MINIMUM): Assume two's complement. (twos_complement_arithmetic): Verify that long_int and time_t are two's complement (or unsigned, in the latter case).
* mktime: check signed shifts on long_int and time_t, tooPaul Eggert2012-05-231-3/+5
| | | | | | * time/mktime.c (SHR): Check that shifts work as desired on the types long_int and time_t too, as SHR is used on such types.
* mktime: do not assume 'long' is wide enoughPaul Eggert2012-05-231-12/+18
| | | | | | | | | * time/mktime.c (verify): Move decl up. (long_int): New type. (leapyear, ydhms_diff, guess_time_tm, __mktime_internal): Use it, to remove assumption in the code that 'long' is wide enough to store year values. This assumption is not true on x32 and on some non-glibc platforms.
* mktime: merge wrapv change from gnulibPaul Eggert2012-05-231-25/+90
| | | | | | | | * time/mktime.c (WRAPV): New macro. (time_t_avg, time_t_add_ok, time_t_int_add_ok): New static functions. (guess_time_tm, __mktime_internal): Do not assume that signed integer overflow wraps around; modern compilers generate code where this assumption is no longer valid.

Price <derek@ximbiot.com> [BZ #1061] * sysdeps/generic/glob.c (glob): Only a 0 return from getlogin_r means success, according to POSIX 1003.2. 2005-06-23 Paul Eggert <eggert@cs.ucla.edu> [BZ #1033] * time/mktime.c: Import from gnulib. The following macros are now consistent with other gnulib code. This does not change mktime's behavior. (TYPE_IS_INTEGER): New macro. (time_t_is_integer): Use it. (TYPE_TWOS_COMPLEMENT): New macro. (twos_complement_arithmetic): Use it. (TYPE_ONES_COMPLEMENT): New macro. (TYPE_MINIMUM, TYPE_MAXIMUM): Now supports signed-magnitude. mktime doesn't use this, but the code now matches other gnulib code. (ranged_convert): Pacify GCC 4.0 in a different way, which generates a few bytes less code. (ranged_convert, __mktime_internal): When calling a function via a pointer P, use P () rather than (*P) (), as we now assume C89 or better.

| | | | | | | | | | 2004-11-10 Paul Eggert <eggert@cs.ucla.edu> [BZ #541] * time/mktime.c (SHR): New macro, which is a portable substitute for >> that should work even on Crays. (TIME_T_MIDPOINT, ydhms_diff, __mktime_internal): Use it. Problem reported by Mark D. Baushke in <http://lists.gnu.org/archive/html/bug-gnulib/2004-11/msg00071.html>.
* [BZ #473, BZ #487]Roland McGrath2004-11-011-126/+212
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2004-10-27 Derek R. Price <derek@ximbiot.com> [BZ #487] This change is imported from gnulib. * time/mktime.c (not_equal_tm) [DEBUG]: Remove redundant check. 2004-10-24 Paul Eggert <eggert@cs.ucla.edu> [BZ #473] * time/tst-mktime.c (main): Don't assume that mktime fails when given time stamps before 1970. It returns negative time_t values instead, for compatibility with BSD. * time/tst-mktime2.c: New file. * time/Makefile (tests): Add it. [BZ #473] Import from gnulib. Revamp to avoid several problems near time_t extrema, and on hosts with 64-bit time_t and 32-bit int. This fixes Debian bug 177940. * time/mktime.c (TIME_T_MIDPOINT): New macro. (ydhms_diff): Renamed from ydhms_tm_diff, with a new signature, which avoids overflow problems on hosts with 64-bit time_t and 32-bit int. All callers changed. Now an inline function. Verify at compile-time that long int is wide enough to avoid these overflow problems. (guess_time_tm): New function. (__mktime_internal): Use it. Avoid overflow when computing yday on hosts with 64-bit long and 32-bit int. Remove tests for 69; no longer needed. Use if rather than #ifdef for LEAP_SECONDS_POSSIBLE so that the code is checked by more compilers. Do not rely on floating point to probe: stick to integer arithmetic, to avoid potential porting problems. Repair potential overflow correctly in the Southern Hemisphere. (localtime_offset): Add a FIXME for the case where time_t is unsigned.
* [BZ #471] Fix imported from gnulib.Roland McGrath2004-10-221-3/+4
| | | | | | | | | * time/mktime.c (leapyear, ydms_tm_diff): Year is of type long int, not int, to avoid problems when tm_year == INT_MAX and tm_mon > 12. (__mktime_intenral): Compute year using long int arithmetic, not int arithmetic, to avoid problems on hosts where time_t and long are 64 bits but int is 32.
* [BZ #468] Import a fix from gnulib.Roland McGrath2004-10-221-1/+1
| | | | | * time/mktime.c [! DEBUG]: Do not include <string.h>. It's needed only if DEBUG is nonzero.

| | | | | | * time/mktime.c [!_LIBC] (__mktime_internal): Define to mktime_internal, to avoid clashes with any __mktime_internal function defined in the standard library.
* [BZ #469] Imported from gnulib.Roland McGrath2004-10-221-7/+12
| | | | | | * time/mktime.c (__isleap): Remove; all uses replaced by: (leapyear): New function, which avoids overflow by not adding 1900 to year before testing whether it is a leap year.

| | | | | | | | | | | | | | | | | | Remove. All uses changed to __localtime_r. (__localtime_r) [!defined _LIBC]: New macro. Include "time_r.h" to get its implementation. Fix compile-command to allow for TIME_R_POSIX. * time/strftime.c (my_strftime_gmtime_r, my_strftime_localtime_r): Remove. All uses changed to __localtime_r and __gmtime_r.

Don't loop if the iteration overflows time_t. Allow a negative step in the iteration. * time/mktime.c: Assume freestanding C89 or better. (HAVE_LIMITS_H, STDC_HEADERS) [defined _LIBC]: Remove; assume they're 1. (__P): Remove; not used. (CHAR_BIT, INT_MIN, INT_MAX): Remove; <limits.h> defines them. (mktime, not_equal_tm, print_tm, check_result, main): Use prototypes. Prototypes use const * where appropriate. (main) [DEBUG]: Fix typo in testing code uncovered by above changes, which caused the testing code to dump core on some hosts.
