Example: upstream addgroup and adduser have ONLY longopts, we should probably go further and get rid of non-standard short options. To this end, make addgroup and adduser "select LONG_OPTS". We had this breakage caused by us even in our own package! #if ENABLE_LONG_OPTS || !ENABLE_ADDGROUP /* We try to use --gid, not -g, because "standard" addgroup * has no short option -g, it has only long --gid. */ argv[1] = (char*)"--gid"; #else /* Breaks if system in fact does NOT use busybox addgroup */ argv[1] = (char*)"-g"; #endif xargs: its lone longopt no longer depends on DESKTOP, only on LONG_OPTS. hwclock TODO: get rid of incompatible -t, -l aliases to --systz, --localtime Shorten help texts by omitting long option when short opt alternative exists. Reduction of size comes from the fact that store of an immediate (an address of longopts) to a fixed address (global variable) is a longer insn than pushing that immediate or passing it in a register.

| | | | | | | | | | | | | | | | | fix broken logic to get the gzip_level_config value from options -1 to -9. This fixes an off-by-one bug that caused gzip -9 output bigger files than the other compression levels. It fixes so that compression level 1 to 3 are actually mapped to level 4 as comments say. It also fixes that levels -4 to -9 is mapped to correct level and avoids out-of-bounds access.

* gzip: do not store timestamp in gzip headerRich Felker2015-02-021-4/+16
| | | | | | | | | | | | | | | | Storing the original file's modification time in the output file is harmful (precludes deterministic results) and unlike official gzip, the busybox version provides no way to suppress this behavior; the -n option is silently ignored. Rather than trying to make -n work, this patch just removes the timestamp-storing functionality. It should be considered deprecated anyway; it's not Y2038-safe and gunzip ignores it by default. Per RFC 1952, 0 is the correct value to store to indicate that there is no timestamp. Signed-off-by: Rich Felker <dalias@libc.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
