This improves performance and avoids problems # with filters that are enabled globally but aren't set up properly # in the temporary repository (e.g., potentially, Git LFS). # # It's not ideal to rely on an edge case of an advanced Git feature, # but the alternatives aren't great either. We want to run `git # commit` interactively for the user; we can't just call # git.make_tree_with_item + `git commit-tree`. And if we populate # the index and not the working tree without using sparse checkout, # then `git commit` will show all files as deleted under "Changes # not staged for commit", which is distracting. # # Manipulating index entries that are excluded by sparse checkout is # extremely dicey: depending on the Git version, `git checkout` and # `git rm` may leave them unchanged and not perform the operation we # requested. So it's safest to generate the new tree before we # enable sparse checkout. After enabling sparse checkout (if our # copy of Git indeed supports it), `git read-tree -u` is one # operation that should be safe: the index update is unconditional, # and the working tree update honors sparse checkout. # # TODO: Audit Braid for operations that could be broken by use of # sparse checkout by the user (rather than internal to `braid # push`)? git.config(['--local', 'core.sparsecheckout', 'true']) File.open('.git/info/sparse-checkout', 'wb') { |f| # Leave the file empty. } end # Update HEAD the same way git.checkout(base_revision) would, but # don't populate the index or working tree (to save us the trouble of # emptying them again before the git.read_tree). git.update_ref(['--no-deref', 'HEAD', base_revision]) git.read_tree_um(new_tree) system('git commit -v') msg "Pushing changes to remote branch #{branch}." git.push([remote_url, "HEAD:refs/heads/#{branch}"]) end FileUtils.rm_r(clone_dir) clear_remote(mirror, ) end |
