f345edc0	2014-05-22T00:05:01	fchdir: port 'open' and 'close' redefinitions to AIX 7.1 * lib/chown.c, lib/clean-temp.c, lib/copy-file.c, lib/execute.c: * lib/fsusage.c, lib/gc-gnulib.c, lib/javacomp.c, lib/mountlist.c: * lib/openat-proc.c, lib/pagealign_alloc.c, lib/progreloc.c: * lib/spawn-pipe.c: Do not #undef 'open' and 'close'. AIX 7 does '#define open open64' and then 'int open64(const char *, int, ...);', which means the declaration for 'open' gets lost if we later '#undef open'. Discovered while building grep pretest 2.18.151-1c770 on AIX 7.1, where the compilation reported the non-fatal error "In function 'openat_proc_name' ... warning: implicit declaration of function 'open'". In this case the error is relatively harmless, but in other cases it might not be so minor.

2392b180	2011-01-11T10:42:55	openat, save-cwd: avoid xmalloc This removes a direct (but undocumented) dependency of openat on xalloc, along with an indirect dependency via save-cwd. It also removes a dependency of save-cwd on xgetcwd, and thereby indirectly on xalloc. This change causes the openat substitute to fall back on save_cwd when memory is tight, and for save_cwd to fail instead of dying when memory is tight, but that's good enough. * lib/openat-proc.c: Include stdlib.h (for malloc), not xalloc.h (for xmalloc). (openat_proc_name): Use malloc, not xmalloc. * lib/save-cwd.c (save_cwd): Use getcwd, not xgetcwd. * modules/save-cwd (Files): Depend on getcwd, not xgetcwd.

24816be6	2010-09-01T13:45:53	fcntl-h, etc.: prefer O_SEARCH to O_RDONLY when applicable POSIX 2008 specifies a new 'open' flag O_SEARCH, which can be used when one needs search access to a directory but not read access. On systems where it is available, it works in some cases where O_RDONLY does not, namely on directories that are searchable but not readable, and which need only to be searchable. If O_SEARCH is not available, fall back to the traditional method of using O_RDONLY. * lib/fcntl.in.h (O_SEARCH): #define to O_RDONLY if not defined. * lib/chdir-long.c (cdb_advance_fd): Use O_SEARCH, not O_RDONLY, when opening a directory that needs only to be searchable. * lib/chdir-safer.c (chdir_no_follow): Likewise. * lib/fts.c (diropen, fts_open, fd_ring_check): Likewise. * lib/openat-proc.c (openat_proc_name): Likewise. * lib/openat.c (openat_needs_fchdir): Likewise. * lib/save-cwd.c (save_cwd): Likewise. * lib/savewd.c (savewd_save, savewd_chdir): Likewise.
