Git prompt hidden without --verbose flag

[zanieb]

The following command hung for a while:

❯ uv pip compile docs/requirements-insiders.in -o docs/requirements-insiders.txt --universal -p 3.12

              ^C

I cancelled it and re-ran with --verbose:

Are you sure you want to continue connecting (yes/no/[fingerprint])? 

Then I could provide the information for the git prompt and move forward.

@ibraheemdev - Is this straightforward?

[zanieb]

I don't see where we're gating this with the verbose flag with a casual look.

[charliermarsh]

Not clear to me how this is appearing even with --verbose.

[zanieb]

Yeah I was confused... haha. Tried to write a MRE but it just fails:

❯ cat ~/bin/git
#/usr/bin/env bash

echo "Content please"
read test

@zanieb @charliermarsh
Hi, I'm a big fan of uv! Thank you as always.

I have found the cause of this.
It seems that the tick of ResolverReporter is erasing the prompt for the git command.
Therefore, if this line is removed, no hang-up will occur.

uv/crates/uv/src/commands/reporters.rs

Line 323 in ec8eee0

root.enable_steady_tick(Duration::from_millis(200));

Could you fix this?
If you don't have time, please point me in the right direction and I'll try to create a PR.
( I am not an expert in Rust, so this may take some time 😅 )

[charliermarsh]

Oh wow, that’s a great find and explains a lot!

[zanieb]

🤔

https://github.com/Agilent/yb/blob/main/yb/src/main.rs#L72 from console-rs/indicatif#594 seems helpful?

I was hit by a similar issue when running:

uv pip install "git+https://github.com/typing/typing_extensions@main"

Note that the correct URL is https://github.com/python/typing_extensions. Without using the --verbose flag, I get the following output and it hangs forever:

Updating https://github.com/typing/typing_extensions (main)
Updating https://github.com/typing/typing_extensions (main)

Only when running in verbose mode, I get:

DEBUG failed to check github HTTP status client error (404 Not Found) for url (https://api.github.com/repos/typing/typing_extensions/commits/main)
DEBUG Performing a Git fetch for: https://github.com/typing/typing_extensions
Username for 'https://github.com':

I assume because the repo can't be found, uv delegates to the git CLI, and because the HTTPS URL was used, the git CLI will use HTTP auth (which is deprecated iirc, maybe it doesn't work anymore).
