`tilt down` hangs when offline due to git pull in extension directory

[beatak]

Expected Behavior

I should be able to run tilt down regardless of my internet connection status.

Current Behavior

When I try to run tilt down while offline, the command gets stuck. It appears to be attempting the following behind the scenes before executing command hooks or proceeding with the normal teardown process:

cd "$LIBRARY_DIR/tilt-dev/tilt_modules/github.com/tilt-dev/tilt-extensions"; git pull

Steps to Reproduce

1. Run tilt up on a Tiltfile that uses extensions (while online)
2. Disconnect from the internet
3. Run tilt down

About Your Use Case

I was just trying to work outside the office, offline. Ideally, tilt down should still work in this scenario without getting blocked by a failed network operation.

hmmm...sorry to hear you're having issues. I was not able to reproduce this problem, given the steps provided.

I used the example go repo - https://github.com/tilt-dev/tilt-example-go/tree/master/3-recommended

Then ran tilt down with the network off:

Loading Tiltfile at: /home/nick/src/tilt-example-go/3-recommended/Tiltfile
# cd /home/nick/.local/share/tilt-dev/tilt_modules/github.com/tilt-dev/tilt-extensions; git pull --ff-only
ssh: Could not resolve hostname github.com: Name or service not known
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
Successfully loaded Tiltfile (83.850796ms)
Deleting kubernetes objects:
→ Deployment/example-go

That's basically what i'd expect -- git should fail immediately, tilt will recognize it's ok, and then will continue with the tear down.

Question: do git operations normally hang indefinitely when you're offline?

[beatak]

Thanks @nicks for taking a look. I'll be swamped until next week, but I'll come back to this issue sometimes soon.

If you have a WireGuard (wg) VPN connection still open, while you're offline, WireGuard will not hang up on the connection, but rather wait until a connection to the wg server has been established, or until a timeout occurs. Depending on whether you are waiting for github.com to resolve in DNS, or you're attempting to connect to github.com over TCP, the timeout duration may vary from 1 minute to indefinitely.

I think it should be possible to disable the git pull step, or to set short timeouts for this operation in general.

$ time tilt down
