* Don't use the argument to time.Zack Weinberg2019-08-212-2/+2
| | | | | | | | | | | | | | | | | | | It doesn't make sense to remove all the internal uses of time. It's still a standard ISO C function, and its callers don't need sub-second resolution and would be unnecessarily complicated if they had to declare a struct timespec instead of just a time_t. However, a handful of places were using the vestigial "result" argument instead of the return value, which is slightly less efficient and also looks strange. Correct this. * misc/syslog.c (__vsyslog_internal) * time/getdate.c (__getdate_r) * time/tst_wcsftime.c (main): Use return value of time, not its argument. * string/strfry.c (strfry) * sysdeps/mach/sleep.c (__sleep): Remove unnecessary casts of NULL in calls to time.
* Make mktime etc. compatible with __time64_tPaul Eggert2019-04-303-32/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Keep these functions compatible with Gnulib while adding __time64_t support. The basic idea is to move private API declarations from include/time.h to time/mktime-internal.h, since the former file cannot easily be shared with Gnulib whereas the latter can. Also, do some other minor cleanup while in the neighborhood. * include/time.h: Include stdbool.h, time/mktime-internal.h. (__mktime_internal): Move this prototype to time/mktime-internal.h, since Gnulib needs it. (__localtime64_r, __gmtime64_r) [__TIMESIZE == 64]: Move these macros to time/mktime-internal.h, since Gnulib needs them. (__mktime64, __timegm64) [__TIMESIZE != 64]: New prototypes. (in_time_t_range): New static function. * posix/bits/types.h (__time64_t) [__TIMESIZE == 64 && !defined __LIBC]: Do not define as a macro in this case, so that portable code is less tempted to use __time64_t. * time/mktime-internal.h: Rewrite so that it does both glibc and Gnulib work. Include time.h if not _LIBC. (mktime_offset_t) [!_LIBC]: Define for gnulib. (__time64_t, __gmtime64_r, __localtime64_r, __mktime64, __timegm64) [!_LIBC || __TIMESIZE == 64]: New macros, mostly moved here from include/time.h. (__gmtime_r, __localtime_r, __mktime_internal) [!_LIBC]: New macros, taken from GNulib. (__mktime_internal): New prototype, moved here from include/time.h. * time/mktime.c (mktime_min, mktime_max, convert_time) (ranged_convert, __mktime_internal, __mktime64): * time/timegm.c (__timegm64): Use __time64_t, not time_t. * time/mktime.c: Stop worrying about whether time_t is floating-point. (__mktime64) [! (_LIBC && __TIMESIZE != 64)]: Rename from mktime. (mktime) [_LIBC && __TIMESIZE != 64]: New function. * time/timegm.c [!_LIBC]: Include libc-config.h, not config.h, for libc_hidden_def. Include errno.h. (__timegm64) [! (_LIBC && __TIMESIZE != 64)]: Rename from timegm. (timegm) [_LIBC && __TIMESIZE != 64]: New function. First cut at publicizing __time64_t
* time/tst-strftime3.c: Disable snprintf warning.DJ Delorie2019-04-031-0/+10
| | | | | | | snprintf will only truncate the output if the data its given is corrupted, but a truncated buffer will not match the "pristine" data's buffer, which is all we need. So just disable the warning via the DIAG macros.

* Fix strptime era handling, add more strftime tests [BZ #24394]DJ Delorie2019-04-013-3/+466
| | | | | | | | | | | | | | | Test the transition points between all the currently listed Japanese era name changes. This includes testing the transition between the first year date and the second year date. This test will help test the upcoming Japanese era name change. Also fixes a fencepost error where the era name isn't properly parsed by strptime in the last (partial) year of the era. Example: if an era change happens in Feb 1990, and again in Aug 1995, that's 5.5 years long, but the 0.5 year wasn't accounted for. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

This patch fixes various code to do this. It only changes code that appears to be mostly following GNU style anyway, not files and directories with substantially different formatting. It is not exhaustive even for files using GNU style (for example, changes to sysdeps files are deferred for subsequent cleanups). Some files changed are shared with gnulib, but most are specific to glibc. Changes were made manually, with places to change found by grep (so some cases, e.g. where the operator was followed by a comment at end of line, are particularly liable to have been missed by grep, but I did include cases where the operator was followed by backslash-newline). This patch generally does not attempt to address other coding style issues in the expressions changed (for example, missing spaces before '(', or lack of parentheses to ensure indentation of continuation lines properly reflects operator precedence).

| | | | | | | | | | | By ordering the suballocations by decreasing alignment, alignment gaps can be avoided. Also use __glibc_unlikely for reading the transitions and type indexes.

* strftime: Set the default width of "%Ey" to 2 [BZ #23758]TAMUKI Shoichi2019-01-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Japanese locales, strftime's alternative year format (%Ey) produces a year numbered within a time period called an _era_. A new era typically begins when a new emperor is enthroned. The result of "%Ey" is therefore usually a one- or two-digit number. Many programs that display Japanese era dates assume that the era year is two digits wide. To improve how these programs display dates during the first nine years of a new era, change "%Ey" to pad one- digit numbers on the left with a zero. This change applies to all locales. It is expected to be harmless for other locales that use the alternative year format (e.g. lo_LA and th_TH, in which "%Ey" produces the year of the Buddhist calendar) as those calendars' year numbers are already more than two digits wide, and this is not expected to change. This change needs to be in place before 2019-05-01 CE, as a new era is scheduled to begin on that date.

* Y2038: make __difftime compatible with 64-bit timeAlbert ARIBAUD (3ADEV)2018-12-201-9/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide a 64-bit-time version of __difftime (but do not assume __time64_t is a signed int so that Gnulib can reuse the code) and make the 32-bit version a wrapper of it. Current difftime expects two time_t arguments and returns a double. To preserve source-code compatibility, its 64-bit-time equivalent expects two __time64_t arguments but still returns a double. This patch was tested by running 'make check' on branch master then applying this patch and its two predecessors 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. This patch was also functionally tested with an ad hoc userland C program which checks the result of difftime for various pairs of 32-bit and, for 64-bit builds, of 64-bit time_t values too. The program was built and run against a glibc with and without the patch, and the results compared to ensure the patch does not change the behavior of difftime. * include/time.h (__difftime64): Add. * time/difftime.c (subtract): convert to 64-bit time. * time/difftime.c (__difftime64): Add. * time/difftime.c (__difftime): Wrap around __difftime64.

| | | | | | | | | | | | | | | | | | | | | | 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.

* mktime: DEBUG_MKTIME cleanupPaul Eggert2018-11-151-160/+2
| | | | | | | The DEBUG_MKTIME code no longer works in glibc or in Gnulib. And it’s no longer needed now that glibc and Gnulib both have their own testing mechanisms for mktime. * time/mktime.c (DEBUG_MKTIME): Remove. All uses removed.
* mktime: fix non-EOVERFLOW errno handlingPaul Eggert2018-11-151-98/+99
| | | | | | | | | | | | | | | [BZ#23789] mktime was not properly reporting failures when the underlying localtime_r fails with errno != EOVERFLOW; it incorrectly treated them like EOVERFLOW failures, and set errno to EOVERFLOW. The problem could happen on non-glibc platforms, with Gnulib. * time/mktime.c (guess_time_tm): Remove, replacing with ... (tm_diff): ... this simpler function, which does not change errno. All callers changed to deal with errno themselves. (ranged_convert, __mktime_internal): Return failure immediately if the underlying function reports any failure other than EOVERFLOW. (__mktime_internal): Set errno to EOVERFLOW if the spring-forward gap code fails.
* mktime: fix bug with Y2038 DST transitionPaul Eggert2018-11-151-1/+3
| | | | | | | | [BZ#23789] * time/mktime.c (ranged_convert): On 32-bit platforms, don’t mishandle a DST transition that jumps over the Y2038 boundary. No such DST transitions are known so this is only a theoretical bug, but we might as well do things right.

| | | | | | | [BZ#23789] * time/mktime.c [!_LIBC && !DEBUG_MKTIME]: Include libc-config.h, not config.h, for __set_errno. (guess_time_tm, __mktime_internal): Set errno to EOVERFLOW on overflow.
* Y2038: Add 64-bit time for all architecturesAlbert ARIBAUD (3ADEV)2018-10-241-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* mktime fix for Gnulib + coreutilsPaul Eggert2018-10-081-1/+1
| | | | | | | | | | | [BZ#23745] This fix affects only Gnulib. Problem discovered when mktime.c was used as part of Gnulib in bleeding-edge Coreutils. * time/mktime.c: (my_tzset) [!_LIBC && !NEED_MKTIME_WORKING && !NEED_MKTIME_WINDOWS]: Do not define since it is not used. Defining an unused static function prompts a warning from GCC when Coreutils is configured with --enable-gcc-warnings.
* Fix mktime localtime offset confusionPaul Eggert2018-09-191-1/+1
| | | | | | | | | | | [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.
* Merge mktime, timegm from upstream GnulibPaul Eggert2018-09-193-316/+254
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [BZ #23603][BZ #16346] This fixes some obscure problems with integer overflow. Although it looks scary, it is almost all a byte-for-byte copy from Gnulib, and the Gnulib code has been tested reasonably well. * include/intprops.h: New file, copied from Gnulib. * include/verify.h, time/mktime-internal.h: New tiny files, simplified from Gnulib. * time/mktime.c: Copy from Gnulib. This has the following changes: Do not include config.h if DEBUG_MKTIME is nonzero. Include stdbool.h, intprops.h, verify.h. Include string.h only if needed. Include stdlib.h on MS-Windows. Include mktime-internal.h. (DEBUG_MKTIME): Default to 0, and simplify later uses. (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. Use these conditionals to express only the code needed on the current platform. In uses of these conditionals, explicitly spell out how _LIBC affects things, so it’s easier to review from a glibc viewpoint. (WRAPV): Remove; no longer needed now that we have systematic overflow checking. (my_tzset, __tzset) [!_LIBC]: New function and macro, to better compartmentalize tzset issues. Move system-dependent tzsettish code here from mktime. (verify): Remove; now done by verify.h. All uses changed. (long_int): Use a more-conservative definition, to avoid integer overflow. (SHR): Remove, replacing with ... (shr): New function, which means we needn’t worry about side effects in args, and conversion analysis is simpler. (TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT, TYPE_SIGNED, TYPE_MINIMUM) (TYPE_MAXIMUM, TIME_T_MIN, TIME_T_MAX, TIME_T_MIDPOINT) (time_t_avg, time_t_add_ok): Remove. (mktime_min, mktime_max): New constants. (leapyear, isdst_differ): Use bool for booleans. (ydhms_diff, guess_time_tm, ranged_convert, __mktime_internal): Use long_int, not time_t, for mktime differences. (long_int_avg): New function, replacing time_t_avg. INT_ADD_WRAPV replaces time_t_add_ok. (guess_time_tm): 6th arg is now long_int, not time_t const *. All uses changed. (convert_time): New function. (ranged_convert): Use it. (__mktime_internal): Last arg now points to mktime_offset_t, not time_t. All uses changed. This is a no-op on glibc, where mktime_offset_t is always time_t. Use int, not time_t, for UTC offset guess. Directly check for integer overflow instead of using a heuristic that works only 99.9...% of the time. 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): Move tzsettish code to my_tzset, and move localtime_offset to within mktime so that it doesn’t need a separate ifdef. (main) [DEBUG_MKTIME]: Speed up by using localtime_r instead of localtime. * time/timegm.c: Copy from Gnulib. This has the following changes: Include mktime-internal.h. [!_LIBC]: Include config.h and time.h. Do not include timegm.h or time_r.h. Make __mktime_internal a macro, and include mktime-internal.h to get its declaration. (timegm): Temporary is now mktime_offset_t, not time_t. This affects only Gnulib.

* Fix year 2039 bug for localtime with 64-bit time_t (bug 22639).Joseph Myers2018-05-183-2/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug 22639 reports localtime failing to handle time offset transitions correctly in 2039 and later on platforms with 64-bit time_t. The problem is the use of SECSPERDAY (constant 86400) in calculations such as t = ((year - 1970) * 365 + /* Compute the number of leapdays between 1970 and YEAR (exclusive). There is a leapday every 4th year ... */ + ((year - 1) / 4 - 1970 / 4) /* ... except every 100th year ... */ - ((year - 1) / 100 - 1970 / 100) /* ... but still every 400th year. */ + ((year - 1) / 400 - 1970 / 400)) * SECSPERDAY; where t is of type time_t and year is of type int. Before my commit 92bd70fb85bce57ac47ba5d8af008736832c955a (an update from tzcode, included in 2.26 and later releases), SECSPERDAY was obtained from a file imported from tzcode, where the value included a cast to int_fast32_t. On 64-bit platforms, glibc defines int_fast32_t to be long int, so 64-bit, but my patch resulted in it changing to int. (The bug would probably have existed even before my patch for x32, which has 64-bit time_t but 32-bit int_fast32_t, but I haven't verified that.) This patch fixes the problem by including a cast to time_t in the definition of SECSPERDAY. (64-bit time support for 32-bit systems should move such code that isn't a public interface to using the internal 64-bit version of time_t throughout.) Tested for x86_64 and x86. [BZ #22639] * time/tzset.c (SECSPERDAY): Cast to time_t. * time/tst-y2039.c: New file. * time/Makefile (tests): Add tst-y2039.

* Fix -Os getc_unlocked linknamespace, localplt issues (bug 15105, bug 19463).Joseph Myers2018-02-211-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the fixes for linknamespace and localplt test failures with -Os that arise from functions not being inlined in that case, this patch fixes such failures for getc_unlocked. __getc_unlocked already exists; this patch makes it explicitly hidden, calls it where needed for namespace reasons, adds an inline function for it when inline functions are used and adds libc_hidden_proto / libc_hidden_weak for getc_unlocked. Tested for x86_64 (both without -Os to make sure that case continues to work, and with -Os to make sure all the relevant linknamespace and localplt test failures are resolved). Because of other such failures that remain after this patch, neither of the bugs can yet be closed.
