In the United States, we have the master repository in one state and a build cluster in a different state. In addition to people in the US doing builds, we have people in other countries (Ireland, India, Israel, Russia, possibly others) doing builds -- using the build cluster. The local mirror of the repository is NFS accessible. The plan is to make builds faster through the use of work trees. The build cluster nodes involved in the build will have a worktree in RAM -- checked out for the duration of the build. Since the worktree is in RAM, it will not be NFS accessible. [Cloning takes 20+ minutes when the network is unloaded. Building, with sources NFS mounted, takes 5-10 minutes.] This presents a few problems. When we are done with a work tree, we want to clean up -- think: prune. But, you cannot prune just one worktree; you have to prune the set. And no machine has access to all the worktrees. So, no machine knows which ones are prunable. There is no 'lock' option to 'add'. If someone does a 'prune' after you do an 'add' and before you do a 'lock', then your 'add' is undone. Are there any plans to add a '[--lock]' option to 'add' to create the worktree in the locked state? And/or plans to add a [<path>...] option to prune to say 'prune only this path / these paths'? If there are no plans, is the above an acceptable interface? And if we implemented it, would it be looked upon favorably? Thanks. ^ permalink raw reply [flat|nested] 10+ messages in thread

By "prune one worktree", did you mean delete one? Or delete a branch the worktree uses and prune the object database? > There is no 'lock' option to 'add'.

And/or > plans to add a [<path>...] option to prune to say 'prune only this path / these paths'? So this is "git worktree prune". Adding "worktree add --locked" sounds reasonable (and quite simple too, because "worktree add" does lock the worktree at creation time; we just need to stop it from releasing the lock). I might be able to do it quickly (it does not mean "available in the next release" though). If you need to just prune "this path", I think it's the equivalent of "git worktree remove" (i.e. delete a specific worktree). Work has been going on for a while to add that command. Maybe it'll be available later this year. > If there are no plans, is the above an acceptable interface? And if we implemented it, would it be looked > upon favorably? Speaking of this use case (and this is my own opinion) I think this is stretching "git worktree" too much. When I created it, I imagined this functionality to be used by a single person. -- Duy ^ permalink raw reply [flat|nested] 10+ messages in thread

"worktree add" does keep a lock on while it's preparing the worktree. If --lock is specified, this lock remains after the worktree is created.

It is a good addition, which is why I added tests and documents, so it may have a chance for inclusion.

Then I saw --detach (instead of > --detached). I didn't care much and went with a verb like the rest. While I personally would prefer --locked, I also prefer keeping it 'parallel construction' with --detach. That is either [--detach][--lock] or [--detached][--locked]. But, ultimately, my intended use is within a script, so even if it was --totally-non-mnemonic-option I would cope.

I think either "--lock" or "--locked" works for me. "--locked' suggests "this is the state I want the tree in" while "--lock" suggests "this is the action I want taken on the tree".
