Improve listing performance by using go-git (#6478) * 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. Signed-off-by: Filip Navara <navara@emclient.com> * Make Signature type alias for object.Signature in go-git. Signed-off-by: Filip Navara <navara@emclient.com> * Fix GetCommitsInfo for repository with only one commit. Signed-off-by: Filip Navara <navara@emclient.com> * Fix PGP signature verification. Signed-off-by: Filip Navara <navara@emclient.com> * Fix issues with walking commit graph across merges. Signed-off-by: Filip Navara <navara@emclient.com> * Fix typo in condition. Signed-off-by: Filip Navara <navara@emclient.com> * Speed up loading branch list by keeping the repository reference (and thus all the loaded packfile indexes). Signed-off-by: Filip Navara <navara@emclient.com> * Fix lising submodules. Signed-off-by: Filip Navara <navara@emclient.com> * Fix build Signed-off-by: Filip Navara <navara@emclient.com> * Add back commit cache because of name-rev Signed-off-by: Filip Navara <navara@emclient.com> * Fix tests Signed-off-by: Filip Navara <navara@emclient.com> * Fix code style * Fix spelling * Address PR feedback Signed-off-by: Filip Navara <navara@emclient.com> * Update vendor module list Signed-off-by: Filip Navara <navara@emclient.com> * Fix getting trees by commit id Signed-off-by: Filip Navara <navara@emclient.com> * Fix remaining unit test failures * Fix GetTreeBySHA * Avoid running `git name-rev` if not necessary Signed-off-by: Filip Navara <navara@emclient.com> * Move Branch code to git module * Clean up GPG signature verification and fix it for tagged commits * Address PR feedback (import formatting, copyright headers) * Make blob lookup by SHA working * Update tests to use public API * Allow getting content from any type of object through the blob interface * Change test to actually expect the object content that is in the GIT repository * Change one more test to actually expect the object content that is in the GIT repository * Add comments
