hi folks.
last year i wrote a zlib based gzip program. it supports everything
that the GNU gzip does, except for timestamps, original file name
saving, and saving the compression level in the gzip header (these
are all features that the zlib library does not support -- yet). i
was thinking about putting this in distrib/utils as it is a *LOT*
smaller than the standard gzip, when i noticed that there is a zcat
there already... with some hacks to make it even smaller. while this
program is considerably smaller, much of this comes from a hack to
stop parts of the zlib library being incorporated (deflate methods
IIRC).
i'm happy for this zcat to remain there for the sun3 stuff (i believe
that it's only used there), but i'd really like to put my gzip in here
as well. here are some (sparc) sizes:
-rwxrwxr-x 1 mrg wsrc 71273 Jun 4 16:10 zcat
-rw-rw-r-- 1 mrg wsrc 2622 Oct 3 1996 zcat.c
-rwxrwxr-x 1 mrg wsrc 114953 Jun 4 16:10 gzip
-rw-rw-r-- 1 mrg wsrc 13089 Jun 3 00:27 gzip.c
text data bss dec hex
98304 8192 3836 110332 1aefc gzip
57344 8192 484 66020 101e4 zcat
does anyone object to me importing my gzip into distrib/utils/gzip_s ?
i plan on using it for the sparc floppies i'm working on (actually,
i'm already using it for them :)
