* fchmodat, lchmod: simplifyPaul Eggert2020-02-232-56/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
