Summary: added gzip compression option
Product: Sorcery
Version: Devel
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P2
Component: Sorcery
AssignedTo: sm-sorcery-bugs AT lists.ibiblio.org
ReportedBy: sybex AT hotmail.com


Added a new option in the sorcery menu "Compression Type" with
options for bzip2 and gzip. This patch was made against the
Sorcery 20021212 devel branch. It patches the following files:

cast
dispel
gaze
sorcery
libsorcery
/etc/sorcery/config

This option will result in compressing all of the file in:

/var/cache/sorcery
/var/log/sorcery/compile

After talking with many sourcemage users it became evident that
many would benefit from a gzip compression option. Compressing
in bzip2 is many times slower than gzip while the benefits are
minimal. In my tests using gzip is several times faster and
compile logs are actually smaller! It appears that bzip2 is not
as efficient for smaller files due to the nature of the
compression algorithms, ie larger overhead.

let me know what you think.
