Poking at this, did I break it or was it never particularly tested? $ ./zcat README zcat: unknown suffix: README $ cat README | ./gunzip | head -n 3 Toybox: all-in-one Linux command line.
--- Getting started $ cat README | gunzip | head -n 3 gzip: stdin: not in gzip format I was trying to see if gzdopen(blah, "r") verifies the gzip header on the data stream and thus fails due to being fed non-gzip data, or if the first read() does that. (I dug up the zlib manual which says it doesn't use the filehandle until read so won't notice if it's invalid, so failure there is basically a malloc failure.) Also, there's a lot of error_exit() calls when the old gzip continues to the next argument instead: $ cat ../README | gzip > one.gz $ cat ../README | gzip > two.gz $ touch one $ sudo chattr +i one $ gunzip one.gz two.gz gzip: one already exists; do you wish to overwrite (y or n)? y gzip: one: Operation not permitted $ ls -l total 12 -rw-rw-r-- 1 landley landley 0 Jan 3 03:22 one -rw-rw-r-- 1 landley landley 3076 Jan 3 03:22 one.gz -rw-rw-r-- 1 landley landley 6624 Jan 3 03:22 two And so on...
