tempname: merge from glibc and coreutils Also, merge in Gnulib’s more-recent methods of making it easier to share between Gnulib and glibc, and fix a few randomness glitches. * lib/tempname.c: Include libc-config.h, not config.h, if !_LIBC. (__set_errno): Remove; libc-config.h does that for us. Do not include <sys/time.h>. (__secure_getenv) [_LIBC]: New macro. (__try_tempname, __getpid, __gettimeofday) [!_LIBC]: Remove macros. (RANDOM_BITS): Rewrite. (RANDOM_VALUE_MAX, BASE_62_DIGITS, BASE_62_POWER): New macros. (random_value): New typedef. (try_file, try_dir, try_nocreate): Move up. (gen_tempname_len, try_tempname_len): New functions. (gen_tempname_len): Use a constant array rather than a switch. (try_tempname_len): Don’t assume string length fits in int. Generalize use of RANDOM_BITS. If _LIBC, don’t assume RANDOM_BITS has enough entropy (it’s a bit short). (__gen_tempname): Rewrite in terms of gen_tempname_len. (__try_tempname): Rewrite in terms of try_tempname_len. * lib/tempname.h (gen_tempname_len, try_tempname_len): New decls. * modules/tempname (Depends-on): Remove gettimeofday, sys_time. Add getentropy, libc-config.
