coverage-5.6b1

• Third-party packages are now ignored in coverage reporting. This solves a few problems:
  • Coverage will no longer report about other people’s code (issue 876). This is true even when using --source=. with a venv in the current directory.
  • Coverage will no longer generate “Already imported a file that will be measured” warnings about coverage itself (issue 905).
• The HTML report uses j/k to move up and down among the highlighted chunks of code. They used to highlight the current chunk, but 5.0 broke that behavior. Now the highlighting is working again.
• The JSON report now includes percent_covered_display, a string with the total percentage, rounded to the same number of decimal places as the other reports’ totals.

Version 6.0.2 — 2021-10-11

• Namespace packages being measured weren't properly handled by the new code that ignores third-party packages. If the namespace package was installed, it was ignored as a third-party package. That problem (issue 1231_) is now fixed.

• Packages named as "source packages" (with source, or source_pkgs, or pytest-cov's --cov) might have been only partially measured. Their top-level statements could be marked as unexecuted, because they were imported by coverage.py before measurement began (issue 1232_). This is now fixed, but the package will be imported twice, once by coverage.py, then again by your test suite. This could cause problems if importing the package has side effects.

• The :meth:.CoverageData.contexts_by_lineno method was documented to return a dict, but was returning a defaultdict. Now it returns a plain dict. It also no longer returns negative numbered keys.

Version 6.0.1 — 2021-10-06

• In 6.0, the coverage.py exceptions moved from coverage.misc to coverage.exceptions. These exceptions are not part of the public supported API, CoverageException is. But a number of other third-party packages were importing the exceptions from coverage.misc, so they are now available from there again (issue 1226_).

• Changed an internal detail of how tomli is imported, so that tomli can use coverage.py for their own test suite (issue 1228_).

• Defend against an obscure possibility under code obfuscation, where a function can have an argument called "self", but no local named "self" (pull request 1210_). Thanks, Ben Carlsson.
