* gzip: add support for --no-name long optionAaro Koskinen2015-10-271-0/+1
| | | | | | | | | | Add support for --no-name long option. Just silently ignore it like the short -n option. This allows to use busybox gzip with Lynx browser. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change makes "tar tf hello_world.txz" work without adding special-casing for ".txz" extension.
