Currently `git annex unused` assumes that all branches (including remote
|
||
|
|
tracking branches) and tags are "used" and finds only objects not used by
|
||
|
|
any of those refs.
|
||
|
|
|
||
|
|
That's a reasonable default, but in some cases, we don't care about
|
||
|
|
specific refs. Perhaps we don't consider remote tracking branches
|
||
|
|
important. Or perhaps we only want objects in HEAD to be considered used.
|
||
|
|
|
||
|
|
This could be handled by adding an option to specify a refspec when running
|
||
|
|
git-annex unused. Only matching refs would be checked. It's probably worth
|
||
|
|
making this be both a command-line option --used-refspec, as well as a
|
||
|
|
annex.used-refspec config setting.
|
||
|
|
|
||
|
|
git's refspec format is not quite right (since it specifies a local side
|
||
|
|
and a remote side for push/pull). But, it can be used as a point of
|
||
|
|
departure. Let's allow wildcards as it does, and use leading '+' to add a
|
||
|
|
ref, and '-' to remove. Let the user specify multiple such expressions,
|
||
|
|
separated by ':'.
|
||
|
|
|
||
|
|
+refs/heads/*:-refs/remotes/*:+refs/tags/*:-refs/tags/old-tag
|
||
|
|
|
||
|
|
Note that this needs to be processed by taking all refs matching any '+',
|
||
|
|
and then removing any of those that match any '-'
|
||
|
|
|
||
|
|
Also, allow use of HEAD, and anything else that `git show-ref` can handle.
