[cli] Stick to unmount as a command name

[ricab]

Description

Use "unmount" as the name of the Multipass command, keeping "umount"
as an alias. Update docs and bash-completion accordingly.

Testing

• Unit tests

  • updated expected help output

• Manual testing steps:

  • multipass help
  • multipass unmount
  • multipass umount
  • make run in docs folder
    • searched for both terms
    • clicked around on unmount links
    • verified redirect

Additional Notes

Like before, the --help and --verbose options are not offered by
auto-completion after a command alias. This is now the case for umount
rather than unmount.

@geoffreynyaga, could I get your eyes on the docs part for this one please? In particular the redirect: it worked locally on my testing, but I was a little surprised to find no other redirects in the same place. Also, copilot complained about "legacy documentation redirect target" even though it didn't make a specific comment. Anything you think is missing? Thanks in advance.

1.17 is going to be released soon, at which point we will drop support for testing earlier versions. I am adding a "no-merge" label for now.

[ricab]

This needs to wait for 1.17 to be out before merging. Alternatively, I could put the special handling for wait-ready back in place, but we should remove it after 1.17 in any case.

Hey @Laefy, I ended up using "unmount" in the mount tests and parameterizing one of them to cover "umount" as well. Here's a successful run https://github.com/canonical/multipass/actions/runs/36763469836

See commit messages for more details.

It's all good! Thank you :)

@ricab Everything looks good to me. The redirect implementation is also correct and I can confidently say that this was a copilot error. Sphinx-reredirects extension expects either relative or absolute paths in the dictionary and you implemented it well.
On a technical sidenote (and extra test): Sphinx spits out _build/reference/command-line-interface/umount/index.html like you'd expect, and it bounces you over to the new unmount page.

<html><head><noscript><meta http-equiv="refresh" content="0; url=../unmount/" /></noscript><script>var target = "../unmount/";if (window.location.hash) {window.location.replace(target + window.location.hash);} else {window.location.replace(target);}</script></head></html>

I have also manually tested the old url and the redirect is in place.

All good!

Ugh, what is going on? 🤔

@copilot any ideas?

From the thread, the docs redirect looks correct: reference/command-line-interface/umount maps to ../unmount/, which resolves to the new command page; it is reasonable for this to be the only redirect in docs/conf.py since it preserves this renamed page’s old URL. The “legacy documentation redirect target” warning appears to have been a false positive, consistent with Geoff’s local verification. I also checked the linked CLI run: it passed. An earlier run on the same commit failed before tests started because its generated shell command had an unmatched quote, so that failure doesn’t point to a regression in the command change.

@copilot, I was referring to the repeated "no response for status checks" just 1 or 2 minutes after this is added to the merge queue. Any idea what could be causing that?

Actions shows merge-group checks were triggered; the long build/test matrix was still running, and one newer queue run was cancelled while an earlier run remained active. I can’t identify a definitive cause for GitHub’s “no response” message from these logs alone. Please compare the branch ruleset’s required check names against the contexts emitted on the synthetic merge-group commit.

@copilot, I was referring to the repeated "no response for status checks" just 1 or 2 minutes after this is added to the merge queue. Any idea what could be causing that?

I checked the merge-queue Actions runs. The merge_group workflow did start promptly: the run beginning at 22:47 started filtering in seconds, then launched lint/docs and the Linux/macOS/Windows jobs. Lint/docs finished in about 2 minutes, but several build/test jobs were still running more than 20 minutes later. A later run was cancelled while those jobs were underway; another run for the same queue ref remained active. So this looks more like pending/superseded merge-group checks than CI never triggering. I can’t confirm why GitHub labels them “no response” from Actions logs alone; the next thing to check is whether the exact required check contexts in the branch ruleset match checks emitted for the synthetic merge_group SHA.
