git-gui: Allow users to rename branches through 'branch -m' Git's native command line interface has had branch renaming support for quite a while, through the -m/-M options to the git-branch command line tool. This is an extremely useful feature as users may decide that the name of their current branch is not an adequate description, or was just entered incorrectly when it was created. Even though most people would consider git-branch to be a Porcelain tool I'm using it here in git-gui as it is the only code that implements the rather complex set of logic needed to successfully rename a branch in Git. Currently that is along the lines of: *) Backup the ref *) Backup the reflog *) Delete the old ref *) Create the new ref *) Move the backed up reflog to the new ref *) Record the rename event in the reflog *) If the current branch was renamed, update HEAD *) If HEAD changed, record the rename event in the HEAD reflog *) Rename the [branch "$name"] section in the config file Since that is some rather ugly set of functionality to implement and get right, and some of it isn't easily accessible through the raw plumbing layer I'm just cheating by relying on the Porcelain.

git-gui: Refactor branch switch to support detached head This is a major rewrite of the way we perform switching between branches and the subsequent update of the working directory. Like core Git we now use a single code path to perform all changes: our new checkout_op class. We also use it for branch creation/update as it integrates the tracking branch fetch process along with a very basic merge (fast-forward and reset only currently). Because some users have literally hundreds of local branches we use the standard revision picker (with its branch filtering tool) to select the local branch, rather than keeping all of the local branches in the Branch menu. The branch menu listing out all of the available branches is simply not sane for those types of huge repositories. Users can now checkout a detached head by ticking off the option in the checkout dialog. This option is off by default for the obvious reason, but it can be easily enabled for any local branch by simply checking it. We also detach the head if any non local branch was selected, or if a revision expression was entered. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
