6.5.0

Version 6.5.0 — 2022-09-29

• The JSON report now includes details of which branches were taken, and which are missing for each file. Thanks, Christoph Blessing. Closes issue 1425.
• Starting with coverage.py 6.2, class statements were marked as a branch. This wasn’t right, and has been reverted, fixing issue 1449. Note this will very slightly reduce your coverage total if you are measuring branch coverage.
• Packaging is now compliant with PEP 517, closing issue 1395.
• A new debug option --debug=pathmap shows details of the remapping of paths that happens during combine due to the [paths] setting.
• Fix an internal problem with caching of invalid Python parsing. Found by OSS-Fuzz, fixing their bug 50381.

6.4.3

Version 6.4.3 — 2022-08-06

• Fix a failure when combining data files if the file names contained glob-like patterns. Thanks, Michael Krebs and Benjamin Schubert.
• Fix a messaging failure when combining Windows data files on a different drive than the current directory, closing issue 1428. Thanks, Lorenzo Micò.
• Fix path calculations when running in the root directory, as you might do in a Docker container. Thanks Arthur Rio.
• Filtering in the HTML report wouldn’t work when reloading the index page. This is now fixed. Thanks, Marc Legendre.
• Fix a problem with Cython code measurement, closing issue 972. Thanks, Matus Valo.

6.4.2

Version 6.4.2 — 2022-07-12

• Updated for a small change in Python 3.11.0 beta 4: modules now start with a line with line number 0, which is ignored. This line cannot be executed, so coverage totals were thrown off. This line is now ignored by coverage.py, but this also means that truly empty modules (like __init__.py) have no lines in them, rather than one phantom line. Fixes issue 1419.
• Internal debugging data added to sys.modules is now an actual module, to avoid confusing code that examines everything in sys.modules. Thanks, Yilei Yang.

6.4.1

Version 6.4.1 — 2022-06-02

• Greatly improved performance on PyPy, and other environments that need the pure Python trace function. Thanks, Carl Friedrich Bolz-Tereick (pull 1381 and pull 1388). Slightly improved performance when using the C trace function, as most environments do. Closes issue 1339.
• The conditions for using tomllib from the standard library have been made more precise, so that 3.11 alphas will continue to work. Closes issue 1390.

6.4

Version 6.4 — 2022-05-22

• A new setting, [run] sigterm, controls whether a SIGTERM signal handler is used. In 6.3, the signal handler was always installed, to capture data at unusual process ends. Unfortunately, this introduced other problems (see issue 1310). Now the signal handler is only used if you opt-in by setting [run] sigterm = true.
• Small changes to the HTML report:
  • Added links to next and previous file, and more keyboard shortcuts: [ and ] for next file and previous file; u for up to the index; and ? to open/close the help panel. Thanks, J. M. F. Tsang.
  • The time stamp and version are displayed at the top of the report. Thanks, Ammar Askar. Closes issue 1351.
• A new debug option debug=sqldata adds more detail to debug=sql, logging all the data being written to the database.
• Previously, running coverage report (or any of the reporting commands) in an empty directory would create a .coverage data file. Now they do not, fixing issue 1328.
• On Python 3.11, the [toml] extra no longer installs tomli, instead using tomllib from the standard library. Thanks Shantanu.
• In-memory CoverageData objects now properly update(), closing issue 1323.

6.3.3

Version 6.3.3 — 2022-05-12

• Fix: Coverage.py now builds successfully on CPython 3.11 (3.11.0b1) again. Closes issue 1367. Some results for generators may have changed.

6.3.2

Version 6.3.2 — 2022-02-20

• Fix: adapt to pypy3.9’s decorator tracing behavior. It now traces function decorators like CPython 3.8: both the @-line and the def-line are traced. Fixes issue 1326.
• Debug: added pybehave to the list of coverage debug and --debug options.
• Fix: show an intelligible error message if --concurrency=multiprocessing is used without a configuration file. Closes issue 1320.

6.3.1

Version 6.3.1 — 2022-02-01

• Fix: deadlocks could occur when terminating processes. Some of these deadlocks (described in issue 1310) are now fixed.
• Fix: a signal handler was being set from multiple threads, causing an error: “ValueError: signal only works in main thread”. This is now fixed, closing issue 1312.
• Fix: --precision on the command-line was being ignored while considering --fail-under. This is now fixed, thanks to Marcelo Trylesinski.
• Fix: releases no longer provide 3.11.0-alpha wheels. Coverage.py uses CPython internal fields which are moving during the alpha phase. Fixes issue 1316.

6.3

Version 6.3 — 2022-01-25

• Feature: Added the lcov command to generate reports in LCOV format. Thanks, Bradley Burns. Closes issues 587 and 626.
• Feature: the coverage data file can now be specified on the command line with the --data-file option in any command that reads or writes data. This is in addition to the existing COVERAGE_FILE environment variable. Closes issue 624. Thanks, Nikita Bloshchanevich.
• Feature: coverage measurement data will now be written when a SIGTERM signal is received by the process. This includes https://docs.python.org/3/library/multiprocessing.html#multiprocessing.Process.terminate, and other ways to terminate a process. Currently this is only on Linux and Mac; Windows is not supported. Fixes issue 1307.
• Dropped support for Python 3.6, which reached end-of-life on 2021-12-23.
• Updated Python 3.11 support to 3.11.0a4, fixing issue 1294.
• Fix: the coverage data file is now created in a more robust way, to avoid problems when multiple processes are trying to write data at once. Fixes issues 1303 and 883.
• Fix: a .gitignore file will only be written into the HTML report output directory if the directory is empty. This should prevent certain unfortunate accidents of writing the file where it is not wanted.
• Releases now have MacOS arm64 wheels for Apple Silicon, fixing issue 1288.
