* gettime: nanotime never existedPaul Eggert2018-09-181-2/+0
| | | | | | | Problem reported by Bruno Haible in: https://lists.gnu.org/r/bug-gnulib/2018-09/msg00082.html * lib/gettime.c (gettime) [HAVE_NANOTIME]: Remove unused code. * m4/gettime.m4 (gl_GETTIME): Don’t check for nanotime.
* timespec: new function current_timespecPaul Eggert2018-09-161-13/+16
| | | | | | | | | | | | | * lib/gettime.c (gettime): Prefer clock_gettime to nanotime, and don’t worry about it failing on a CLOCK_REALTIME arg. POSIX requires it to succeed and I don’t know of any counterexamples where the fallbacks would work. (current_timespec): New function, taken from Emacs. It is more convenient than gettime, and can help register allocation. * lib/timespec.h: Include arg-nonnull.h. (current_timespec): New declaration. (gettime, settime): Declare args to be nonnull. * modules/timespec (Depends-on): Add snippet/arg-nonnull.

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.

(Time of day items): Mention the possibility of leap seconds. Problem reported by Dr. David Alan Gilbert. * lib/chdir-long.c (cdb_free): Don't bother trying to open directory for write access: POSIX says that must fail. * lib/fts.c (diropen): Likewise. * lib/save-cwd.c (save_cwd): Likewise. * lib/chdir-long.c (cdb_free): Open with O_NOCTTY | O_NONBLOCK as well, for minor improvements on hosts that lack O_DIRECTORY. * lib/gettime.c (gettime) [!defined OK_TO_USE_1S_CLOCK]: Report an error at compile-time if only a 1-second nominal clock resolution is found. * lib/lchmod.h: New file. * lib/mkdir-p.c: Include lchmod.h, lchown.h. (make_dir_parents): Use lchown rather than chown, and lchmod rather than chmod. * lib/mountlist.c (ME_DUMMY): "none" and "proc" file systems are dummies too. Problem with "none" reported by Bob Proulx. Problem with "proc" reported by n0dalus. * lib/mountlist.c: Include <limits.h>. (dev_from_mount_options) [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]: New function. It no longer assumes "dev=" has the System V meaning on Linux (since it doesn't). It also parses "dev=" more carefully. (read_file_system_list) [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]: Use it. MOUNTED_GETMNTENT2 is new here; the code didn't used to look for dev= in that case. * lib/posixtm.h (PDS_PRE_2000): New macro. * lib/posixtm.c (year): Arg is now syntax_bits rather than allow_century. All usages changed. Reject dates outside the range 1969-1999 if PDS_PRE_2000 is used. * modules/mkdir-p (Files): Add chdir-safer.c, chdir-safer.h, lchmod.h, chdir-safer.m4, lchmod.m4. * modules/openat: Add mkdirat.c, openat-priv.h. * modules/lib-ignore: New file. * lib/version-etc.c (COPYRIGHT_YEAR): Update to 2006. Rewrite fts.c not to change the current working directory, by using openat, fstatat, fdopendir, etc.. * lib/fts.c [! _LIBC]: Include "openat.h", "unistd--.h", and "fcntl--.h". [_LIBC] (fchdir): Don't undef or define; no longer used. (FCHDIR): Define in terms of cwd_advance_fd rather than fchdir. Now, this `function' always succeeds, and consumes its file descriptor parameter -- so callers must not close such FDs. Update callers. (diropen_fd, opendirat, cwd_advance_fd): New functions. (diropen): Add parameter, SP. Adjust all callers. Implement using diropen_fd, rather than open. (fts_open): Initialize new member, fts_cwd_fd. Remove fts_rft-setting code. (fts_close): Close fts_cwd_fd, if necessary. (__opendir2): Define in terms of opendir or opendirat, depending on whether the FST_NOCHDIR flag is set. (fts_build): Since fts_safe_changedir consumes its FD, and since this code must do `closedir(dirp)', dup the dirfd(dirp) argument, and close the dup'd file descriptor upon failure. (fts_stat): Use fstatat(...AT_SYMLINK_NOFOLLOW) in place of lstat. (fts_safe_changedir): Tweak semantics to reflect that this function now calls cwd_advance_fd and hence consumes its FD argument. * lib/fts_.h [struct FTS] (fts_cwd_fd): New member. (fts_rft): Remove now-unused member. * lib/openat.c (fchownat): New function. * lib/openat.h (fchmodat, fchownat): Declare. (chmodat, lchmodat): Define convenience functions. (chownat, lchownat): Likewise. * lib/chdir-safer.h, chdir-safer.c: New files. * lib/modechange.c (mode_compile): Reject an invalid mode string that starts with an octal digit. From Andreas Gruenbacher. * lib/openat.c: Include "fcntl--.h" and "unistd--.h", to map open and dup to open_safer and dup_safer, respectively. (openat_permissive): Fix typo in comment. * lib/openat.c: Don't include <stdlib.h>, <unistd.h>, <fcntl.h>, "gettext.h"; either no longer needed or are guaranteed by openat.h. (_): Remove; no longer needed. (openat): Renamed from rpl_openat; no need for rpl_openat since openat.h renames openat for us. Replace most of the body with a call to openat_permissive, to avoid duplicate code. Port to (probably hypothetical) environments were mode_t is wider than int. (openat_permissive): Require mode arg, so that we can check types better. Put it just after flags. Change cwd failure indicator from pointer-to-bool to pointer-to-errno-value. All callers changed. Invoke openat_save_fail and/or openat_restore_fail if cwd_errno is null, so that openat can call us. (openat_permissive, fdopendir, fstatat, unlinkat): Simplify errno handling to avoid some duplicate code, as it's OK to set errno on success. * lib/openat.h: Revamp code so that function macros depend on __OPENAT_PREFIX only, not also on AT_FDCWD. (openat_ro): Remove. Caller changed to use openat_permissive. (openat_permissive): Now a macro, if not a function. (openat_restore_fail, openat_save_fail): Now always functions, since mkdirat needs them even if __OPENAT_PREFIX is defined. * lib/openat-priv.h: New file, defining macros used by mkdirat.c and openat.c. * lib/mkdirat.c: Include openat-priv.h. Remove definitions of macros defined therein. * lib/openat.c: Likewise. * lib/mkdirat.c (mkdirat): New file and function. * lib/openat.h (mkdirat): Declare. * lib/openat.c (fdopendir): Don't change errno when returning non-NULL. * lib/openat.h (openat_permissive): Declare. (openat_ro): Define. * lib/openat.c (EXPECTED_ERRNO): New macro. (openat_permissive): New function -- used in remove.c rewrite. (all functions): Set errno just before returning, only if there was an actual failure. Use EXPECTED_ERRNO rather than comparing against only ENOTDIR. Emulate openat-family functions using Linux's procfs, if possible. Idea and some code based on Ulrich Drepper's glibc changes. * lib/openat.c: (BUILD_PROC_NAME): New macro. Include <stdio.h>, <string.h>, "alloca.h" and "intprops.h". (rpl_openat): Emulate by trying to open /proc/self/fd/%d/%s, before falling back on save_cwd and restore_cwd. (fdopendir, fstatat, unlinkat): Likewise. * lib/openat.c (fstatat, unlinkat): Perform the syscall directly, skipping the save_cwd...restore_cwd overhead, if FILE is absolute. * lib/openat.c (rpl_openat): Use the promoted type (int), not mode_t, as second argument to va_arg. Otherwise, some versions of gcc warn that `if this code is reached, the program will abort'. Add POSIX ACL support * lib/acl.h (copy_acl, set_acl): Add declarations. * lib/acl.c (acl_entries): Add fallback implementation for POSIX ACL systems other than Linux. (chmod_or_fchmod): New function: use fchmod when possible, and chmod otherwise. (file_has_acl): Add a POSIX ACL implementation, with a Linux-specific subcase. (copy_acl): Add: copy an acl and S_ISUID, S_ISGID, and S_ISVTX from one file to another. Fall back to fchmod/chmod when acls are unsupported. (set_acl): Add: set a file's acl and S_ISUID, S_ISGID, and S_ISVTX to a defined value. Fall back to fchmod/chmod when acls are unsupported. * m4/lib-ignore.m4: New file. * m4/lchmod.m4: New file. * m4/chdir-safer.m4: New file. * m4/openat.m4 (gl_FUNC_OPENAT): Require and compile mkdirat.c. Require openat-priv.h. * m4/acl.m4 (AC_FUNC_ACL): Add POSIX ACL and Linux-specific acl tests.

Use it only on GNU/Linux hosts, since the workaround shouldn't be needed elsewhere. * m4/gethrxtime.m4, m4/xnanosleep.m4: New files. * m4/gettime.m4 (gl_GETTIME): Check for nanotime.
