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 $targetThis 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.
