Sorry, something went wrong.
Currently modules which are imported early are misreported in coverage. This has a fix which is documented in the dev guide, but the fix isn't being used in the CI. This PR adds in that fix.

How do I add the 'skip news' label to this? |

this seems to be working now, for example coverage for re is correctly showing as 93% when previously it was showing 60% with the global statements showing as uncovered. See https://codecov.io/gh/python/cpython/tree/64d521b5d34c25b83d0472608d1eab3a6334bf59/Lib |

This looks like it will break periodically, maybe we could find a way to avoid hardcoding the version?

Agreed, although I couldn't find a simple alternative. I tried .../python*/... which does set the pythonpath to the right thing when echo'd, it doesn't seem to pick it up on the following command. If anyone can suggest a better alternative that would be great

This is how the python3.9 is built looking at https://github.com/python/cpython/blob/master/Lib/venv/__init__.py#L129-L131:
| export PYTHONPATH=./.venv/lib/python3.9/site-packages/coverage/fullcoverage | |
| export PYTHONPATH=./.venv/lib/$(./python -c "import sys; print('python%d.%d' % sys.version_info[:2])")/site-packages/coverage/fullcoverage |

That is a clever idea! Thinking about it, export PYTHONPATH=./.venv/lib/$(ls .venv/lib | grep python | head -n 1)/site-packages/coverage/fullcoverage would also work and might be a bit simpler as it doesn't depend on sys, it just gets the name of that python* directory.

Whatever works and is accepted by a core dev is fine by me, you can also use find .venv -name fullcoverage which may be more robust.

@vstinner @brettcannon, looks like you have both added to the CI pipeline in the past. Do either of you have any suggestions /opinions on this update to the test coverage calculation? Thanks |
