Darcs.Repository.Packs
Description
Packs are an optimization that enable faster repository cloning over HTTP.
A pack is actually a tar.gz file that contains many files that would otherwise
have to be transfered one by one (which is much slower over HTTP).
Two packs are created at the same time by createPacks:
- The basic pack, contains the pristine tree.
- The patches pack, contains the set of patches of the repository.
The paths of these files are _darcs/packs/basic.tar.gz and
_darcs/packs/patches.tar.gz. There is also _darcs/packs/pristine which
indicates the pristine hash at the moment of the creation of the packs. This
last file is useful to determine whether the basic pack is in sync with the
current pristine of the repository.
