Bump coverage from 7.13.5 to 7.14.0

Bumps coverage from 7.13.5 to 7.14.0.

Changelog

Sourced from coverage's changelog.

Version 7.14.0 — 2026-05-10

• Feature: now when running one of the reporting commands, if there are parallel data files that need combining, they will be implicitly combined before creating the report. There is no option to avoid the combination; let us know if you have a use case that requires it. Thanks, Tim Hatch <pull 2162_>. Closes issue 1781.

• Fix: the output from combine was too verbose, listing each file considered. Now it shows a single line with the counts of files combined, files skipped, and files with errors. The -q flag suppresses this line. The old detailed lines are available with the new --debug=combine option.

• Fix: running a Python file through a symlink now sets the sys.path correctly, matching regular Python behavior. Fixes issue 2157_.

• Fix: Collector.flush_data could fail with "RuntimeError: Set changed size during iteration" when a tracer in another thread added a line to the per-file set that add_lines (or add_arcs) was iterating. The values passed to CoverageData are now snapshotted via dict.copy() and set.copy(), which are atomic under the GIL. Thanks, Alex Vandiver <pull 2165_>_.

• Fix: the soft keyword lazy is now bolded in HTML reports.

• We are no longer testing eventlet support. Eventlet started issuing stern deprecation warnings that break our tests. Our support code is still there.

Greptile Summary

Bumps the pinned coverage test dependency from 7.13.5 to 7.14.0 in pyproject.toml. The new release is a minor version update with no breaking changes.

• Implicit combine-before-report (new feature): when parallel .coverage.* data files exist, coverage will now automatically combine them before generating a report. This could change CI behaviour if the project collects parallel coverage data, but the test extras here use coverage directly so the impact is limited.
• Bug fixes: quieter combine output, thread-safety fix in Collector.flush_data, and correct sys.path when running a file through a symlink.

Confidence Score: 5/5

Safe to merge — only a single-line version bump for a test-only dependency with no breaking changes in the new release.

The change touches only the pinned coverage version used in testing. The 7.14.0 release adds a quality-of-life auto-combine feature and three bug fixes; none affect library behaviour or the project's own code.

No files require special attention.
