Release Notes

coveragepy/coveragepy (coverage)

v7.14.0

Compare Source

• 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.
