A lot of the code coverage issues reported are in helper debug functions; including these makes our numbers look a fair bit worse for code that's realistically not part of the production build.

While this is a mechanical change, this is also a fairly invasive change, so I want to get feedback on it before proceeding with a merge.

Summary by CodeRabbit

  • Chores
    • Updated coverage reporting to exclude generated data and debug-only code, helping keep coverage results focused on application code. No runtime behavior or user-facing functionality changed.

Walkthrough

This change adds GCOVR exclusion markers around debug-only code across src/, including diagnostics, logging, allocation counters, declarations, initialization, and PCH bookkeeping. It also excludes generated data files from Codecov reporting. Runtime behavior and public declarations remain unchanged.

Changes: Coverage exclusion annotations

Layer / File(s) Summary
Debug-only compiler code
src/*
Existing debug output, counters, diagnostics, helper routines, declarations, macros, and initialization blocks are enclosed by GCOVR_EXCL_START and GCOVR_EXCL_STOP markers.
Generated-file coverage configuration
.github/codecov.yml
Codecov now ignores generated IFC files and generated Unicode and builtin data tables.

Priority: Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Suggested reviewers: darkarc, jhsedg, daveedvdv

Merge Risk: High · up to 19493

This change is meant to affect only coverage reporting. However, one exclusion marker in src/expr.c was placed inside an existing documentation comment, which breaks the comment and stops the compiler build. The build fails until both markers are removed from that comment. The rest of the coverage annotations appear safe.

Full details: Title check

Explanation

The title "RFC: Code cov exclude debug []" is partially related to the changeset. The change adds GCOVR_EXCL_START/GCOVR_EXCL_STOP markers around debug-only code and excludes generated IFC and Unicode data files from Codecov in .github/codecov.yml. The title names the debug-code exclusion, which is the main part of the change. It omits the generated-file exclusion. The trailing "[]" and the "RFC:" prefix add noise, and "Code cov" is an unusual spelling of Codecov.

Full details: Docstring Coverage

Explanation

Docstring coverage is 85.98% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 107 functions across 37 files. (69 skipped: 1 unsupported, 13 too large, 55 over the file limit.)

I think that's too many changes just for one specific tool.
