I'm glad it turned out to be so little missing actually. Reusing
ObjectWalk saved a lot of code in the pack writer, and for the most
part our existing data access structures were already well organized.
Yeah, I actually expected that this feature implementation would cause
more changes. But existence of transport and rev-walking frameworks in
jgit helped a lot. Jgit code changed significantly between my first look
at it (march/april) and GSoC start date.

Finally, we've got some support for pack writing! It's not that
power that C git version offers, but something usable. Delta
generation is not supported. Although we can reuse deltas and objects,
and support all other (I hope) options of git-pack-objects directly or
indirectly, most importantly --thin.
Pack writing and some other features are tested, seem to work.
This implementation of packing is not a very valuable thing directly
(achieving efficient storage), however it's a base for enhancements
and can be used for sending packs over net (with some assumptions).
It's more a "repacking" than "packing" tool.
Yup. The critical part here is jgit can now format a pack file,
which means we can now actually implement native push over the
local pipe (to fork+exec'd git-receive-pack) or over SSH. That
is one of the major missing features in the Eclipse plugin, so
this is a huge milestone for us. Thank you Marek.
Hey, I'm here for doing this, they even pay me for that fun;)
