Support custom file system for @TempDir

[nipafx]

Jupiter's @TempDir does not allow the configuration of custom file systems. It would be nice if it would.

A key motivation for me to open this issue is that custom file systems are the only thing that Pioneer's @TempDir can do that Jupiter's can't. Since Jupiter's is quite a bit more powerful than ours now, we'd like to remove our extension (this also prevents confusion for users), but we don't feel comfortable doing that as long as there's a feature we offer that you don't.

If Jupiter isn't fundamentally opposed to such a feature, we could implement it and open a PR.

Team decision: Since the Extension backing Jupiter's @TempDir is currently registered globally, implementing this is not straightforward. In addition, at this time, we have not yet received great interest in such a feature within Jupiter itself. In light of that, we'd like to focus our resources on some of the more popular outstanding issues in Jupiter. If it later turns out that there's significant community interest to include it in Jupiter we may revisit this issue at that time.

Not sure how they relate. 😃 Should we (Pioneer) consider working on this to create a PR or would you prefer if we didn't?

[marcphilipp]

Well, even if you put in the work to submit a PR we'd have to review it. Moreover, we would discuss how the API and implementation should roughly look like before that. So, for now, we'd prefer that you didn't. I hope you understand. 🙂

I hope you understand.

Of course, no worries. Just wanted to make sure.

This issue has been automatically marked as stale because it has not had recent activity. Given the limited bandwidth of the team, it will be automatically closed if no further activity occurs. Thank you for your contribution.

I think this issue is valuable.

[marcphilipp]

Now that @TempDir is created per declaration by default, that might make an approach that configures it locally feasible.

[scordio]

Although the custom file system could/will be specified per declaration, it'd still be useful to have a way to set it globally, for example with a configuration property (rationale at #2889 (comment)).

@marcphilipp @sbrannen is this up for grabs? I would like to work on it if that's fine with you.
