Package Update Change
coverage major ==5.2.1 -> ==6.4

Release Notes

nedbat/coveragepy

v6.4

Compare Source

  • A new setting, :ref:config_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 <pull 1364_>_.

    • The timestamp and version are displayed at the top of the report. Thanks, Ammar Askar <pull 1354_>*. 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 <pull 1359_>_.

  • In-memory CoverageData objects now properly update(), closing issue 1323_.

v6.3.2

Compare Source

  • 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 :ref:coverage debug <cmd_debug> and :ref:cmd_run_debug options.

  • Fix: show an intelligible error message if --concurrency=multiprocessing is used without a configuration file. Closes issue 1320_.

v6.3.1

Compare Source

  • 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 <pull 1317_>_.

  • 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_.

v6.2

Compare Source

  • Feature: Now the --concurrency setting can now have a list of values, so that threads and another lightweight threading package can be measured together, such as --concurrency=gevent,thread. Closes issue 1012_ and issue 1082_.

  • Fix: A module specified as the source setting is imported during startup, before the user program imports it. This could cause problems if the rest of the program isn't ready yet. For example, issue 1203_ describes a Django setting that is accessed before settings have been configured. Now the early import is wrapped in a try/except so errors then don't stop execution.

  • Fix: A colon in a decorator expression would cause an exclusion to end too early, preventing the exclusion of the decorated function. This is now fixed.

  • Fix: The HTML report now will not overwrite a .gitignore file that already exists in the HTML output directory (follow-on for issue 1244_).

  • API: The exceptions raised by Coverage.py have been specialized, to provide finer-grained catching of exceptions by third-party code.

  • API: Using suffix=False when constructing a Coverage object with multiprocessing wouldn't suppress the data file suffix (issue 989_). This is now fixed.

  • Debug: The coverage debug data command will now sniff out combinable data files, and report on all of them.

  • Debug: The coverage debug command used to accept a number of topics at a time, and show all of them, though this was never documented. This no longer works, to allow for command-line options in the future.

v6.1.2

Compare Source

  • Python 3.11 is supported (tested with 3.11.0a2). One still-open issue has to do with exits through with-statements <issue 1270_>_.

  • Fix: When remapping file paths through the [paths] setting while combining, the [run] relative_files setting was ignored, resulting in absolute paths for remapped file names (issue 1147_). This is now fixed.

  • Fix: Complex conditionals over excluded lines could have incorrectly reported a missing branch (issue 1271_). This is now fixed.

  • Fix: More exceptions are now handled when trying to parse source files for reporting. Problems that used to terminate coverage.py can now be handled with [report] ignore_errors. This helps with plugins failing to read files (django_coverage_plugin issue 78_).

  • Fix: Removed another vestige of jQuery from the source tarball (issue 840_).

  • Fix: Added a default value for a new-to-6.x argument of an internal class. This unsupported class is being used by coveralls (issue 1273_). Although I'd rather not "fix" unsupported interfaces, it's actually nicer with a default value.

v6.1.1

Compare Source

  • Fix: The sticky header on the HTML report didn't work unless you had branch coverage enabled. This is now fixed: the sticky header works for everyone. (Do people still use coverage without branch measurement!? j/k)

  • Fix: When using explicitly declared namespace packages, the "already imported a file that will be measured" warning would be issued (issue 888_). This is now fixed.

v6.0.2

Compare Source

  • 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.

v6.0.1

  • 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.

v5.5

  • coverage combine has a new option, --keep to keep the original data files after combining them. The default is still to delete the files after they have been combined. This was requested in issue 1108_ and implemented in pull request 1110_. Thanks, Éric Larivière.

  • When reporting missing branches in coverage report, branches aren't reported that jump to missing lines. This adds to the long-standing behavior of not reporting branches from missing lines. Now branches are only reported if both the source and destination lines are executed. Closes both issue 1065_ and issue 955_.

  • Minor improvements to the HTML report:

    • The state of the line visibility selector buttons is saved in local storage so you don't have to fiddle with them so often, fixing issue 1123_.

    • It has a little more room for line numbers so that 4-digit numbers work well, fixing issue 1124_.

  • Improved the error message when combining line and branch data, so that users will be more likely to understand what's happening, closing issue 803_.

  • The text report produced by coverage report now always outputs a TOTAL line, even if only one Python file is reported. This makes regex parsing of the output easier. Thanks, Judson Neer. This had been requested a number of times (issue 1086*, issue 922*, issue 732_).

  • The skip_covered and skip_empty settings in the configuration file can now be specified in the [html] section, so that text reports and HTML reports can use separate settings. The HTML report will still use the [report] settings if there isn't a value in the [html] section. Closes issue 1090_.

  • Combining files on Windows across drives now works properly, fixing issue 577*. Thanks, Valentin Lab <pr1080_>*.

  • Fix an obscure warning from deep in the decimal module, as reported in issue 1084.

  • Update to support Python 3.10 alphas in progress, including PEP 626: Precise line numbers for debugging and other tools <pep626_>_.

  • When using --source on a large source tree, v5.x was slower than previous versions. This performance regression is now fixed, closing issue 1037_.

  • Mysterious SQLite errors can happen on PyPy, as reported in issue 1010_. An immediate retry seems to fix the problem, although it is an unsatisfying solution.

  • The HTML report now saves the sort order in a more widely supported way, fixing issue 986*. Thanks, Sebastián Ramírez (pull request 1066*).

  • The HTML report pages now have a :ref:Sleepy Snake <sleepy> favicon.

  • Wheels are now provided for manylinux2010, and for PyPy3 (pp36 and pp37).
