coverage 7.14.0

on Python PyPI

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. 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.
• 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.
