Diffball is a differencing suite I've been working on for a while, supporting multiple binary patch formats (xdelta, bdelta, bdiff, gdiff4...), and w/ preliminary unified gdiff support, and easy framework for supporting compression, and dropping new formats/algs in. Since diffball functions as a binary differencer, it's patches produce md5 correct reconstructed files. My intention, is to base distfile diff'ing upon it- at the very least it's a rather useful utility (imho). While diffball has just had it's initial release (2 days ago as of this message), it's been in development for 4 months, working for 3 out of the 4. I'm confident in it's stability, the only detractor is documentation- it has an appropriate set of man files, although I do need to make them less spartan, write out out the Readme, and add the remaining 0.4 features (detailed in the TODO file). Suggested location being sys-apps/diffball, although that's only my peon level suggestion... thanks, bdh

Complaints about strnlen, and make failures regarding libmath functions (sqrt for instance) have been resolved as of diffball-0.4_pre2. Diffball is currently at 0.4_pre3, and I'll be updating this ebuild once 0.4_pre4 is released (which is planned for/around 10/31/2003). In general, the updates since the initial pre-0.40 release have been cleaning it up for general usage, lessening memory req's, optimizing worst run conditions, etc. 0.4_pre4 will likely become the actual 0.40 release.
Created attachment 20151 [details] v0.4_pre4 ebuild renamed ebuild for 0.4_pre4
Renamed ebuild for v0.4_pre4, the most current version of diffball. Best to use this version, rather then earlier pre{2,3}, since this is the culmination of fixes, run-time improvements, and general cleanup. Basically in need of user testing.
Created attachment 20152 [details] 0.4_pre4- fixed SRC_URI, no other change. fixed a rather dumb mistake in the src_uri . Now points to the correct location.
added to portage
