[code-infra] Codecov is broken on Core and X (original) (raw)

Investigate why codecov doesn't post status checks anymore
=> codecov not answering.
Investigate optimizing coverage and re-enabling on X
=> disabled because 3x to 4x slowdown. vitest team is aware

codecov broken beyond repair
- status checks are missing
- coverage upload flaky: this causes our CI stability to be way down.
coverage generation in vitest unacceptably slow
codecov checks missing for considerable amount of time, with few push-backs of the teams

conclusion: We're removing codecov for now and disabling coverage generation in CI. We'll leave coverage configuration in the test env for who wants to play with it locally.
