[PATCH 0/6] receive-pack: use ODB transactions to stage object writes

[Justin Tobler <jltobler@gmail.com>]

Greetings,

This patch series replaces direct usage of the `tmp_objdir` interfaces
in git-receive-pack(1) to instead use the `odb_transaction` interfaces
to create/manage a staging area to write objects to. The purpose of this
change is to get git-receive-pack(1) one step closer to being ODB
backend agnostic. For now, the object writes themselves are still
"files" backend specific due to being handled by the git-index-pack(1)
and git-unpack-objects(1) child processes. This will be tackled in a
separate series though.

Thanks,
-Justin
