Title:
gzip --rsyncable not rsyncable
Status in gzip package in Ubuntu:
Fix Released
Status in gzip package in Debian:
Fix Released
Bug description:
i use gzip --rsyncable to compress postgresql 9 db dumps for rsyncing
from an east-coast colo to a west-coast colo. the dumps are always
changing in small ways so this compression speeds up the rsync by
quite a bit. both the following tests are with a large text dump file
on both sides, the local is newer than the remote.
a gzip 1.3.12 (with
http://archive.ubuntu.com/ubuntu/pool/main/g/gzip/gzip_1.3.12-9ubuntu1.diff.gz)
session ends with the usual infodump like this:
rj@fudge:~$ rsync -Pvazl latest-linux-pg9.gz rj@cake:

latest-linux-pg9.gz
1857354904 100% 2.77MB/s 0:10:39 (xfer#1, to-check=0/1)
sent 310747861 bytes received 301381 bytes 456418.55 bytes/sec
total size is 1857354904 speedup is 5.97
but with the ubuntu server LTS gzip 1.4 i'm getting little or no
speedup:
rj@fudge:~$ rsync -Pvazl latest-linux-pg9.gz rj@cake:
Password:
sending incremental file list
latest-linux-pg9.gz
1802447002 100% 634.16kB/s 0:46:15 (xfer#1, to-check=0/1)
sent 1739614120 bytes received 297265 bytes 617318.21 bytes/sec
total size is 1802447002 speedup is 1.04
i haven't taken a look at the code or data to suggest the difference,
but the result is noticeable. basically, not super-critical because i
can build previous versions with previous-version patches, but i
figured i should report it.
