Subject Re: Forcing specific index file names
Date Wed, 15 Dec 2010 19:41:23 GMT

: In my testing, when the filenames are the same, doing an xdelta on the
: files (mainly the file that contains most of the data, the .cfs file),
: there is a significant reduction in the size of the patch file created.

AS noted elsewhere in this thread, the filenames themselves are 
significant because they are tracked in the segments file and indicate 
generational information.

files with the same names should be the same, files with differnet names 
should be very different -- but if your binary diff tool is finding 
commonalities between files in new segments as the index grows overtime, 
and you feel like you can take advantage of this, then i would suggest 
using a simple tool like "tar" to combine all of the index files int oa 
single file with a predictable name before running your diff tool.
