Tracking the deletion of remote branches? [message #1743027]

I just noticed that EGit still shows as "remote tracking" a branch that recently got deleted on the remote - even after pull. Is EGit supposed to (automatically) remove the remote tracking branch on pull, or is there a specific gesture to achieve this?

FWIW, Collect Garbage didn't do the job, either.

Not sure if this is a (intentionally?) missing feature, or a bug or a PEBKAC?

thanks,
Stephan

I guess this is a missing feature in EGit/JGit that we don't clean up remote tracking branches. What I can say is that the garbage collection can't repair that situation. Garbage collection is a pure local-only operation. When GC is running and there are some remote tracking branches the GC does not know whether the corresponding branches on the remote git server still exist or not. And GC is not asking all the configured remotes for the complete list of refs. I think it should be a feature of the fetch operation (that operation which is responsible to modify the remote tracking branches) to delete local remote tracking branches if the corresponding branch on the remote server does not exist anymore. It could be a little bit tricky if you fetch like "git fetch origin features/abc/12*". You would first have to find out which remote tracking branches exist locally and match that pattern, compare that with the response from the server and delete those remote tracking branches which lost their counterpart.

Ciao

I think the basic work has already been done, FetchCommand.setRemoveDeletedRefs() could be used to implement git fetch -p.
This option is already avaible in JGit's CLI fetch command.

I was about to file a bug for this but then found https://bugs.eclipse.org/338054 Smile

I'm still to try this.
Maybe this should just be advertised in the UI somehow?

So, what do you think about making this discoverable in the UI?

Yes, FetchCommand could use method setRemoveDeletedRefs to set delete remote refercense . But the local tracking branch are still left there.
If anybody want to update local branch, they should manage it by themselves, I think.
