[DanielNoord]

After updating to coveralls ~= 3.3 and trying to run the CI of pylint with coverage ~= 6.1 we are running into an error. Based on the traceback I'm reporting it here. Running with coverage ~= 5.5 does not fail.

Run of the CI can be found here https://github.com/PyCQA/pylint/runs/4104109552?check_suite_focus=true

Perhaps #330 only adds support for 6.0 and not 6.1?

Happy to provide any other details or data necessary to fix this!

It might be easier to address in coveragepy. I opened nedbat/coveragepy#1273 for it.

@TheKevJames Will need to pin the version to the next release of coverage as this will be fixed in that version.

[DanielNoord]

@TheKevJames Please pin coverage to 6.1.2 😄

[cdce8p]

Please pin coverage to 6.1.2

@DanielNoord I wouldn't suggest pinning coverage. It's much better to exclude incompatible versions in this case. -> #337

[DanielNoord]

Yeah, that's what I meant. Thanks for opening the PR 🎉

[TheKevJames]

Hey folks, thanks for investigating this and special thanks to @cdce8p for the fix. I've just released coveralls v3.3.1 with the included restriction.

Separately, I'll investigate further our use of internal APIs from coverage-py as mentioned in nedbat/coveragepy#1273 . I really thought we'd managed to fix that issue...
