* Use go-git for tree reading and commit info lookup. Signed-off-by: Filip Navara <navara@emclient.com> * Use TreeEntry.IsRegular() instead of ObjectType that was removed. Signed-off-by: Filip Navara <navara@emclient.com> * Use the treePath to optimize commit info search. Signed-off-by: Filip Navara <navara@emclient.com> * Extract the latest commit at treePath along with the other commits. Signed-off-by: Filip Navara <navara@emclient.com> * Fix listing commit info for a directory that was created in one commit and never modified after. Signed-off-by: Filip Navara <navara@emclient.com> * Avoid nearly all external 'git' invocations when doing directory listing (.editorconfig code path is still hit). Signed-off-by: Filip Navara <navara@emclient.com> * Use go-git for reading blobs. Signed-off-by: Filip Navara <navara@emclient.com> * Make SHA1 type alias for plumbing.Hash in go-git.
