What would it take to get the "gzip --rsyncable" feature included in
Cygwin gzip?
For anybody not familiar with it, this feature enables huge bandwidth
savings when needing to regularly replicate large compressed files
between remote systems where there are only small changes to the files.
It is available in RedHat gzip 1.3.3 and Debian gzip 1.3.12, but not in
Cygwin gzip 1.3.12 - perhaps because it has not been adopted upstream by
gnu.org ?
I believe that this feature was first developed by renowned Linux Kernel
hacker Rusty Russell in about 2001:
http://www.mail-archive.com/rsync@lists.samba.org/msg00637.html
A patch for Cygwin gzip 1.3.12 was created by G.W. Haywood in 2008:
http://lists-archives.org/cygwin/36094-gzip-rsyncable-patch.html
Currently I can not even build the *unpatched* gzip-1.3.12-2 from source
with Cygwin... but that's another issue (already posted).
Really hopeful that this useful feature could just be added to the
standard Cygwin gzip, but not sure who to ask, hence this posting.
Thanks,
Yuri McPhedran
