* fchmodat, lchmod: simplifyPaul Eggert2020-02-238-125/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It appears that we may have overengineered lchmod and fchmodat, in that the code was prepared for some hypothetical platforms but was so complicated that it was hard to understand. I attempted to improve the situation by simplifying the code when this simplification should not hurt on real platforms; we can re-add complexity later to port to platforms I didn’t know about. * lib/fchmodat.c (fchmodat): * lib/lchmod.c (lchmod): Put the ‘defined __linux__ || defined __ANDROID__’ #ifdef only around the /proc code that needs it. * lib/fchmodat.c (fchmodat): Coalese calls to orig_fchmodat. * lib/lchmod.c (__need_system_sys_stat_h): Omit; no longer needed. Do not include <config.h> twice. (orig_lchmod) [HAVE_LCHMOD]: Remove, since we need not wrap lchmod on any known hosts. (lchmod): Do not defer to fchmodat, so that the lchmod module need not depend on the fchmodat module (which is a circular dependency). Do not use openat, since ‘open’ suffices. Coalesce calls to lchmod/chmod. * lib/lchmod.c, lib/sys_stat.in.h (lchmod): * m4/sys_stat_h.m4 (REPLACE_FSTAT): * modules/lchmod (Depends-on, configure.ac): * modules/sys_stat (Depends-on): Do not worry about replacing lchmod, since that shouldn’t happen. * m4/lchmod.m4 (gl_FUNC_LCHMOD): Do not check for fchmodat. Do not worry about whether lchmod works on non-symlinks, since every known lchmod works on non-symlinks. * modules/lchmod (Depends-on): Remove circular dependency on fchmodat.
* lchmod: Fix link error on Solaris 10 (regression from 2020-02-16).Bruno Haible2020-02-232-11/+15
| | | | | * lib/lchmod.c (lchmod): Use the code with lstat and chmod also when NEED_LCHMOD_NONSYMLINK_FIX is not defined.

* chmodat, chownat: new modulesPaul Eggert2020-02-2210-21/+122
| | | | | | | | | | | | | | | | | | | | | | | These are split from fchmodat, fchownat. GNU Emacs needs the POSIX-specified fchmodat, but not the gnulib-specified chmodat and lchmodat. Split the latter two into a new module chmodat. Similarly for fchownat. This the same basic idea for why statat was split from fstatat on 2013-01-23. * lib/chmodat.c, lib/openat.h (CHMODAT_INLINE): Rename from FCHMODAT_INLINE. All uses changed. * lib/chownat.c, lib/openat.h (CHOWNAT_INLINE): Rename from FCHOWNAT_INLINE. All uses changed. * lib/openat.h: (chownat, lchownat): Define if GNULIB_CHOWNAT, not GNULIB_FCHOWNAT. (chmodat, lchmodat): Define if GNULIB_CHMODAT, not GNULIB_FCHMODAT. * modules/chmodat, modules/chownat, tests/test-chownat.c: New files. * modules/fchmodat (Files:): Remove lib/fchmodat.c. (configure.ac): Remove fchmodat module indicator. (Makefile.am): Omit chmodat.c. (Maintainer): Add self. * modules/fchownat: Similarly, but for chown. * tests/test-fchownat.c (BASE): Don't define if already defined. (do_chown, do_lchown) [!TEST_CHOWNAT]: Test fchownat instead.

* largefile: remove _DARWIN_USE_64_BIT_INODEPaul Eggert2020-02-212-3/+9
| | | | | | | | | | It’s not needed in currently-supported macOS versions, and was problematic anyway in MacOS X 10.5 which was the only version that could use it. Problem reported by Peter Eisentraut in: https://lists.gnu.org/r/bug-autoconf/2020-02/msg00004.html * m4/largefile.m4 (AC_SYS_LARGEFILE): Don’t define _DARWIN_USE_64_BIT_INODE.
