Rework `no_coverage` to `coverage(off)` #114656

bossmc · 2023-08-09T14:59:57Z

As discussed at the tail of #84605 this replaces the no_coverage attribute with a coverage attribute that takes sub-parameters (currently off and on) to control the coverage instrumentation.

Allows future-proofing for things like coverage(off, reason="Tested live", issue="#12345") or similar.

Fantastic!
I've been getting to do it myself but couldn't find the time. While I was thinking about it I think I thought some grace period would be nice given how widespread this feature is (if it's not too hard to do). Otherwise it might be hard to coordinate with crates like https://github.com/taiki-e/coverage-helper

bossmc · 2023-08-09T18:32:23Z

The old model uses a feature-flag called no_coverage to control access to an attribute called no_coverage (which, as you say, might be baked into various tools). The new model uses the coverage feature flag to control access to the coverage attribute. I suppose we could just leave the old feature and attribute as they were (with a lint warning that they're being dropped in favour of the new one?) to act as a grace period.

💔 Test failed - checks-actions

Zalathar · 2023-09-05T09:39:25Z

A few of the tests in tests/run-coverage use #[no_coverage], so they’ll need to be updated and re-blessed.

Note that those tests only run if you have the profiler runtime enabled in your config.toml (otherwise they automatically get ignored silently).

Fix the error message for `#![feature(no_coverage)]` When rust-lang#114656 was written, the feature flag to replace `no_coverage` was originally spelled `coverage`, but it was eventually changed to `coverage_attribute` instead.
