NAME Vcdiff::Xdelta3 - Xdelta3 backend for Vcdiff SYNOPSIS use Vcdiff::Xdelta3; my $delta = Vcdiff::Xdelta3::diff($source, $target); my $target2 = Vcdiff::Xdelta3::patch($source, $delta); ## $target2 eq $target This module is a backend to the Vcdiff module and isn't usually used directly. DESCRIPTION Xdelta3 is a delta encoding library by Joshua MacDonald. The Xdelta3 source code is embedded into this module and built as a shared object. The "xdelta3" command-line binary is not built. PROS * Doesn't have arbitrary size limitations on source, target, or delta files. * Has a really neat feature that lets you merge VCDIFF deltas into a single delta. Unfortunately this module doesn't expose that yet. CONS * GPL licensed * Build system is really weird. I didn't bother figuring out how to run Xdelta3's test-suite when installing the CPAN module which is unfortunate. Note that installing this module does still run the shared test-suite in Vcdiff.
