[bitbake-devel] [PATCH 4/4] bb.fetch.git: truncate branches to SRCREV

[Christopher Larson]

From: Christopher Larson <chris_larson at mentor.com>

This removes the commits after SRCREV up to the branch HEAD, as they aren't
needed for us, and just increase the size of the tarball. The user can always
`git fetch` to pull down those commits. Repack/prune the repository before
archiving it to ensure those commits are physically removed.
