Enable coverage script on any test .py files changes:

if no new lines in converted-ethereum-tests.txt, then seek for .py files with tests and compare the coverage
from before and after PR, otherwise it compares the coverage from test repo and .py produced tests as before.

Script is reworked. use uv to run fill correctly
remove retesteth to simplify the script
use changed files github macro to detect changed files

Only one comment, I think it should simplify the logic and make it a bit less fragile.

Hey @winsvega, I'd love to see this on every PR. Have a look at #839, which I think reduces the complexity on our side.

[winsvega]

Merged with #839

[winsvega]

need to exclude prague folder from coverage. but also need to check how change files behave if changes are done to prague and outside of prague.

I just tried out the flow locally and it's working well with the negative path matches in the Changed Files plugin 👍

A few minor comments below:

• Is there any reason why you're not filling with xdist enabled? The flow took 21m 32s locally and the main fill call was 13 mins of this.
• We should also ignore Osaka for now?

-n auto might be breaking >> log capture.
the script is not designed to check huge test amount.

This is great, thanks for implementing this!

I had to create a dummy PR to verify this because act is acting funny when running this workflow for some reason. I think we can merge as is because at the end of the day we need the workflow to work on the CI and not necessarily locally, but we can eventually revisit and see if we can fix it somehow.

Yes. Changed files gives me crypto not found error. The author says he doesn't use this in any way.

Dan doesn't have this issue.
