Description Jeff Johnson 2002-01-26 14:46:36 EST

Here's a patch from Rusty Russell through alikins to add --rsyncable
to the gzip command line that shouldn't break anything else.

FWIW, the equivalent patch for zlib is gonna be internalized
in rpm for payload compression. You've been warned :-)

What does this patch do - what is "--rsyncable" ?

Comment 3 Jeff Johnson 2002-01-28 16:08:48 EST

If (and only if) --rsyncable is specified, then the compression
algorithm changes to preserve rsync's block boundaries on
compressed data. This leads to ~1% degradation in the
size of the compressed text, but can lead to dramatic improvements
when the compressed text is rsync'd.

Try a google search on "gzip.rsync.patch2" for details, there's
a talk given at a linux conference in Oz by Rusty Russell, more.

Comment 4 Trond Eivind Glomsrxd 2002-06-21 11:20:02 EDT

It was added in 1.3.2-3. It's just been removed, but that's a separate issue :).
