* Add bits/types/ wrappers for stddef.h and stdarg.h types.Zack Weinberg2020-01-081-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We rely on the compiler's stddef.h and stdarg.h to define size_t, ptrdiff_t, wchar_t, NULL, and __gnuc_va_list, and to implement a convention that allows us to request the definition of a specific one: for instance #define __need_size_t #include <stddef.h> is expected to define size_t but not any of the other things stddef.h defines. This patch hides that convention behind a set of bits/types/ headers, which allows check-obsolete-constructs.py to verify that none of our headers include these headers unconditionally. (Both of them define at least one item in the user namespace that no other header is supposed to expose.) It will also facilitate coping with compilers that don’t implement the __need convention. (That scenario is not hypothetical, see the next patch.) Only public headers use the new bits headers. Non-public headers and .c files in our codebase, that were formerly defining __need macros, now just include stddef.h and/or stdarg.h without any __need macros. A few files didn’t need to be including stddef.h / stdarg.h at all. Uses of NULL in public headers that aren’t expected to define NULL are changed to a bare 0. bits/NULL.h is only used by headers that are expected to define NULL. malloc.h and printf.h were, in fact, including stddef.h and/or stdarg.h unconditionally; they no longer do that. This broke a few of our test cases, which are fixed by adding appropriate inclusions to the relevant .c files. * stdlib/bits/NULL.h * stdlib/bits/types/__va_list.h * stdlib/bits/types/ptrdiff_t.h * stdlib/bits/types/size_t.h * stdlib/bits/types/va_list.h * stdlib/bits/types/wchar_t.h: New headers defining a single type or macro each. * stdlib/Makefile: Install new headers. * include/bits/NULL.h * include/bits/types/__va_list.h * include/bits/types/ptrdiff_t.h * include/bits/types/size_t.h * include/bits/types/va_list.h * include/bits/types/wchar_t.h: New wrapper headers. * malloc/malloc.h: Don’t include stdio.h or stddef.h.

* Create bits/types headers for most remaining __T_defined macros.Zack Weinberg2020-01-082-9/+2

The remaining uses of the original __T_defined idiom are: __error_t_defined in files shared with gnulib, which probably has to remain as is; ____gwchar_t_defined in inttypes.h, which may not be necessary anymore and should be addressed separately, and __ldiv_t_defined and __lldiv_t_defined in stdlib.h, ditto. Our handling of LFS types is a little inconsistent: some headers declare both off_t and off64_t (for instance) when _LARGEFILE64_SOURCE, others will only declare off_t regardless of _LARGEFILE64_SOURCE. I don't know if this was intentional or not. I am tempted to centralize responsibility for _LARGEFILE64_SOURCE as well as _FILE_OFFSET_BITS=64 in bits/types/off_t.h (etc) so that any header that declares off_t will automatically also declare off64_t when _LARGEFILE64_SOURCE. sunrpc/rpc/types.h is special, because it is included in files compiled by the *build* compiler (cross-rpcgen-objs), and therefore it cannot unconditionally assume bits/types headers are available. What I did was have it include the appropriate bits/types headers only if including sys/types.h did not cause __BIT_TYPES_DEFINED__ to be defined. This will do the right thing when an installed rpc/types.h is included by application code compiled without __USE_MISC in effect. During the build, we rely on the fact that we compile all of our own code with __USE_MISC in effect. This is fragile, but should be acceptable for code that's no longer built by default anyway. scripts/check-obsolete-constructs.py ensures that only sys/types.h and rpc/types.h include the bits/types/ headers that define obsolete types. * posix/bits/types/blkcnt64_t.h * posix/bits/types/blkcnt_t.h * posix/bits/types/blksize_t.h * posix/bits/types/dev_t.h * posix/bits/types/fsblkcnt64_t.h * posix/bits/types/fsblkcnt_t.h * posix/bits/types/fsfilcnt64_t.h * posix/bits/types/fsfilcnt_t.h * posix/bits/types/fsid_t.h * posix/bits/types/gid_t.h * posix/bits/types/id_t.h * posix/bits/types/ino64_t.h * posix/bits/types/ino_t.h * posix/bits/types/intptr_t.h * posix/bits/types/key_t.h * posix/bits/types/loff_t.h * posix/bits/types/mode_t.h * posix/bits/types/nlink_t.h * posix/bits/types/off64_t.h * posix/bits/types/off_t.h * posix/bits/types/pid_t.h * posix/bits/types/socklen_t.h * posix/bits/types/ssize_t.h * posix/bits/types/suseconds_t.h * posix/bits/types/uid_t.h * posix/bits/types/useconds_t.h: New single-declaration headers for standard types canonically defined by sys/types.h, sys/socket.h, or inttypes.h but also exposed by other headers under some circumstances.

* Use clock_gettime to implement gettimeofday.Adhemerval Zanella2019-10-301-10/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consolidate generic gettimeofday implementation to use clock_gettime. Linux ports that still provide gettimeofday through vDSO are not changed. Remove sysdeps/unix/clock_gettime.c, which implemented clock_gettime using gettimeofday; new OS ports must provide a real implementation of clock_gettime. Rename sysdeps/mach/gettimeofday.c to sysdeps/mach/clock_gettime.c and convert into an implementation of clock_gettime. It only supports CLOCK_REALTIME; Mach does not appear to have any support for monotonic clocks. It uses __host_get_time, which provides at best microsecond resolution. Hurd is currently using sysdeps/posix/clock_getres.c for clock_getres; its output for CLOCK_REALTIME is based on sysconf (_SC_CLK_TCK), and I do not know whether that gives the correct result. Unlike settimeofday, there are no known uses of gettimeofday's vestigial "get time zone" feature that are not bugs. (The per-process timezone support in localtime and friends is unrelated, and the programs that set the kernel's offset between the hardware clock and UTC do not need to read it back.) Therefore, this feature is dummied out. Henceforth, if gettimeofday's "struct timezone" argument is not NULL, it will write zeroes to both fields. Any program that is actually looking at this data will thus think it is running in UTC, which is probably more correct than whatever it was doing before. [__]gettimeofday no longer has any internal callers, so we can now remove its internal prototype and PLT bypass aliases. The __gettimeofday@GLIBC_2.0 export remains, in case it is used by any third-party code. It also allows to simplify the arch-specific implementation on x86 and powerpc to remove the hack to disable the internal route to non iFUNC variant for internal symbol. This patch also fixes a missing optimization on aarch64, powerpc, and x86 where the code used on static build do not use the vDSO.

| | | | | | | | | | | | | | | | | | | | | timespec_get is the same function as clock_gettime, with an obnoxious coating of NIH painted on it by the ISO C committee. In addition to the rename, it takes its arguments in a different order, it returns 0 on *failure* or a positive number on *success*, and it requires that all of its TIME_* constants be positive. This last means we cannot directly reuse the existing CLOCK_* constants for it, because those have been allocated starting with CLOCK_REALTIME = 0 on all existing platforms. This patch simply promotes the sysdeps/posix implementation to universal, and removes the Linux-specific implementation, whose apparent reason for existing was to cut out one function call's worth of overhead.

* Consolidate and deprecate ftimeZack Weinberg2019-10-303-18/+18
| | | | | | | | | | | | | | | | | | | | | | | | | ftime is an obsolete variation on gettimeofday, offering only millisecond time resolution; it was probably a system call in ooold versions of BSD Unix. For historic reasons, we had three implementations of it. These are all consolidated into time/ftime.c, and then the function is deprecated. For some reason, the implementation of ftime in terms of gettimeofday was rounding rather than truncating microseconds to milliseconds. In all the other places where we use a higher-resolution time function to implement a lower-resolution one, we truncate. ftime is changed to match, just for tidiness' sake. Like gettimeofday, ftime tries to report the time zone, and using that information is always a bug. This patch dummies out the reported timezone information; the timezone and dstflag fields of the returned "struct timeb" will always be zero.

* Use clock_settime to implement settimeofday.Zack Weinberg2019-10-303-8/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unconditionally, on all ports, use clock_settime to implement settimeofday. Remove sysdeps/unix/clock_settime.c, which implemented clock_settime by calling settimeofday; new OS ports must henceforth provide a real implementation of clock_settime. Hurd had a real implementation of settimeofday but not of clock_settime; this patch converts it into an implementation of clock_settime. It only supports CLOCK_REALTIME and microsecond resolution; Hurd/Mach does not appear to have any support for finer-resolution clocks. The vestigial "set time zone" feature of settimeofday complicates the generic settimeofday implementation a little. The only remaining uses of this feature that aren't just bugs, are using it to inform the Linux kernel of the offset between the hardware clock and UTC, on systems where the hardware clock doesn't run in UTC (usually because of dual-booting with Windows). There currently isn't any other way to do this. However, the callers that do this call settimeofday with _only_ the timezone argument non-NULL. Therefore, glibc's new behavior is: callers of settimeofday must supply one and only one of the two arguments. If both arguments are non-NULL, or both arguments are NULL, the call fails and sets errno to EINVAL. When only the timeval argument is supplied, settimeofday calls __clock_settime(CLOCK_REALTIME), same as stime. When only the timezone argument is supplied, settimeofday calls a new internal function called __settimezone. On Linux, only, this function will pass the timezone structure to the settimeofday system call. On all other operating systems, and on Linux architectures that don't define __NR_settimeofday, __settimezone is a stub that always sets errno to ENOSYS and returns -1. The settimeoday syscall is enabled on Linux by the flag COMPAT_32BIT_TIME, which is an option to either 32-bits ABIs or COMPAT builds (defined usually by 64-bit kernels that want to support 32-bit ABIs, such as x86). The idea to future 64-bit time_t only ABIs is to not provide settimeofday syscall. The same semantics are implemented for Linux/Alpha's GLIBC_2.0 compat symbol for settimeofday. There are no longer any internal callers of __settimeofday, so the internal prototype is removed. Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, powerpc64-linux-gnu, powerpc-linux-gnu, and aarch64-linux-gnu.

* Finish move of clock_* functions to libc. [BZ #24959]Zack Weinberg2019-09-0411-2/+772
| | | | | | | | | | | | | | | | In glibc 2.17, the functions clock_getcpuclockid, clock_getres, clock_gettime, clock_nanosleep, and clock_settime were moved from librt.so to libc.so, leaving compatibility stubs behind. Now that the dynamic linker no longer insists on finding versioned symbols in the same library that originally defined them, we do not need the stubs anymore, and this means we don't need GLIBC_PRIVATE __-prefix aliases for most of the functions anymore either. (clock_gettime still needs one.) For ports added before 2.17, libc.so needs to provide two symbol versions for each, the default at GLIBC_2.17 plus a compat version matching what librt had. While I'm at it, move the clock_*.c files and their tests from rt/ to time/.

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

* time: Avoid alignment gaps in __tzfile_readFlorian Weimer2019-02-041-30/+27
| | | | | | | | | | | By ordering the suballocations by decreasing alignment, alignment gaps can be avoided. Also use __glibc_unlikely for reading the transitions and type indexes. In the 8-byte case, two reads are now needed because the transitions and type indexes are no longer adjacent. The separate call to __fread_unlocked does not matter from a performance point of view because __tzfile_read is only invoked rarely.
* time: Use struct alloc_buffer in __tzfile_readFlorian Weimer2019-02-031-49/+50
| | | | | | | The computation of tzspec_len is moved in front of the total_size computation, so that the allocation size computation and the suballocations are next to each other. Also add an assert that tzspec_len is positive when it is actually used later.
* time: Use int, not long int, for internal GMT offsetsFlorian Weimer2019-02-032-7/+7
| | | | | | | The GMT offset can be outside the range of a 16-bit int type, which is presumably the reason why long int was used in struct tm. We cannot change struct tm, but we can change the internal type for the offset.

* 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.
