In issue #2836 of libgit2, the speed of libgit2’s file:// protocol for git operations is found to be very slow. This is further corrobarated by rad init taking 13 hours to initialise the hardenedbsd ports repository.

There are two areas where the heartwood project uses libgit2 to push using the file protocol. The first is when via the trasnport::local smart transport registration and the second is the final push to storage in the git-remote-rad binary.

When both these push operations are changed to use the git binary instead, the ports repository can be initialised in less than 10 minutes (nearly 100x speed up).

This change is clearly required if heartwood wishes to support larger repositories.

Changes:

• Avoid unwrap
• Use helper working_copy function to get a working copy’s directory, one level above the .git folder.

Changes:

• remove emacs autosave file

Changes:

• Remove helper in favour of using git2::Repository::work_dir

Rebased.
