Release Notes

coveragepy/coveragepy (coverage)

v7.13.0

Compare Source

  • Feature: coverage.py now supports :file:.coveragerc.toml configuration files. These files use TOML syntax and take priority over :file:pyproject.toml but lower priority than :file:.coveragerc files. Closes issue 1643_ thanks to Olena Yefymenko <pull 1952_>_.

  • Fix: we now include a permanent .pth file which is installed with the code, fixing issue 2084. In 7.12.1b1 this was done incorrectly: it didn't work when using the source wheel (py3-none-any). This is now fixed. Thanks, Henry Schreiner <pull 2100_>.

  • Deprecated: when coverage.py is installed, it creates three command entry points: coverage, coverage3, and coverage-3.10 (if installed for Python 3.10). The second and third of these are not needed and will eventually be removed. They still work for now, but print a message about their deprecation.

  • The HTML report now shows separate coverage totals for statements and branches, as well as the usual combined coverage percentage. Thanks to Ryuta Otsuka for the discussion <issue 2081_>_ and the implementation <pull 2085_>_.

  • The JSON report now includes separate coverage totals for statements and branches, thanks to Ryuta Otsuka <pull 2090_>_.

  • Fix: except* clauses were not handled properly under the "sysmon" measurement core, causing KeyError exceptions as described in issue 2086_. This is now fixed.

  • Fix: we now defend against aggressive mocking of open() that could cause errors inside coverage.py. An example of a failure is in issue 2083_.

  • Fix: in unusual cases where a test suite intentionally exhausts the system's file descriptors to test handling errors in open(), coverage.py would fail when trying to open source files, as described in issue 2091_. This is now fixed.

  • A small tweak to the HTML report: file paths now use thin spaces around slashes to make them easier to read.

v7.11.3

Compare Source

  • Fix: the 7.11.1 changes meant that conflicts between a requested measurement core and other settings would raise an error. This was a breaking change from previous behavior, as reported in issue 2076_ and issue 2078_.

    The previous behavior has been restored: when the requested core conflicts with other settings, another core is used instead, and a warning is issued.

  • For contributors: the repo has moved from Ned's nedbat GitHub account_ to the coveragepy GitHub organization_. The default branch has changed from master to main.

v7.11.2

Compare Source

  • Fix: using the "sysmon" measurement core in 7.11.1, if Python code was claimed to come from a non-Python file, a NotPython exception could be raised. This could happen for example with Jinja templates compiled to Python, as reported in issue 2077_. This is now fixed.

  • Doc: corrected the first entry in the 7.11.1 changelog.

.. _issue 2077: #​2077

.. _changes_7-11-1:

v7.11.1

Compare Source

  • Fix: some chanages to details of how the measurement core is chosen, and how conflicting settings are handled. The "sysmon" core cannot be used with some conurrency settings, with dynamic context, and in Python 3.12/3.13, with branch measurement.

    • If the core is not specified and defaults to "sysmon" (Python 3.14+), but other settings conflict with sysmon, then the "ctrace" core will be used instead with no warning. For concurrency conflicts, this used to produce an error, as described in issue 2064_.

    • If the "sysmon" core is explicitly requested in your configuration, but other settings conflict, an error is now raised. This used to produce a warning.

  • Fix: some multi-line case clauses or for loops (and probably other constructs) could cause incorrect claims of missing branches with the sys.monitoring core, as described in issue 2070_. This is now fixed.

  • Fix: when running in pytest under coverage, a breakpoint() would stop in the wrong frame, one level down from where it should, as described in issue 1420_. This was due to a coverage change in v6.4.1 that seemed to give a slight performance improvement, but I couldn't reproduce the performance gain, so it's been reverted, fixing the debugger problem.

  • A new debug option --debug=core shows which core is in use and why.

  • Split sqlite debugging information out of the sys :ref:coverage debug <cmd_debug> and :ref:cmd_run_debug options since it's bulky and not very useful.

  • Updated the :ref:howitworks page to better describe the three different measurement cores.

  • Performance: with branch coverage in large files, generating HTML, JSON, or LCOV reports could take far too long due to some quadratic behavior when creating the function and class index pages. This is now fixed, closing issue 2048_. Thanks to Daniel Diniz for help diagnosing the problem.

  • Most warnings and a few errors now have links to a page in the docs explaining the specific message. Closes issue 1921_.

  • Added patch = fork for times when the built-in forking support is insufficient.

  • Fix: patch = execv also inherits the entire coverage configuration now.

.. _changes_7-10-3:

v7.10.3

Compare Source

  • Fixes for patch = subprocess:

    • If subprocesses spawned yet more subprocesses simultaneously, some coverage could be missed. This is now fixed, closing issue 2024_.

    • If subprocesses were created in other directories, their data files were stranded there and not combined into the totals, as described in issue 2025_. This is now fixed.

    • On Windows (or maybe only some Windows?) the patch would fail with a ModuleNotFound error trying to import coverage. This is now fixed, closing issue 2022_.

    • Originally only options set in the coverage configuration file would apply to subprocesses. Options set on the coverage run command line (such as --branch) wouldn't be communicated to the subprocesses. This could lead to combining failures, as described in issue 2021_. Now the entire configuration is used in subprocesses, regardless of its origin.

    • Added debug=patch to help diagnose problems.

  • Fix: really close all SQLite databases, even in-memory ones. Closes issue 2017_.

v7.10.1

  • Fix: the exclusion for if TYPE_CHECKING: was wrong: it marked the branch as partial, but it should have been a line exclusion so the entire clause would be excluded. Improves issue 831_.

  • Fix: changed where .pth files are written for patch = subprocess, closing issue 2006_.

.. _issue 2006: #​2006

v7.10.0

Compare Source

  • A new configuration option: ":ref:config_run_patch" specifies named patches to work around some limitations in coverage measurement. These patches are available:

    • patch = _exit lets coverage save its data even when :func:os._exit() <python:os._exit> is used to abruptly end the process. This closes long-standing issue 310_ as well as its duplicates: issue 312, issue 1673, issue 1845, and issue 1941.

    • patch = subprocess measures coverage in Python subprocesses created with :mod:subprocess, :func:os.system, or one of the :func:execv <python:os.execl> or :func:spawnv <python:os.spawnl> family of functions. Closes old issue 367, its duplicate issue 378 and old issue 689_.

    • patch = execv adjusts the :func:execv <python:os.execl> family of functions to save coverage data before ending the current program and starting the next. Not available on Windows. Closes issue 43_ after 15 years!

  • The HTML report now dimly colors subsequent lines in multi-line statements. They used to have no color. This gives a better indication of the amount of code missing in the report. Closes issue 1308_.

  • Two new exclusion patterns are part of the defaults: ... is automatically excluded as a line and if TYPE_CHECKING: is excluded as a branch. Closes issue 831_.

  • A new command-line option: --save-signal=USR1 specifies a signal that coverage.py will listen for. When the signal is sent, the coverage data will be saved. This makes it possible to save data from within long-running processes. Thanks, Arkady Gilinsky <pull 1998_>_.

  • A new configuration option: ":ref:config_report_partial_also" is a list of regexes to add as pragmas for partial branches. This parallels the ":ref:config_report_exclude_also" setting for adding line exclusion patterns.

  • A few file path configuration settings didn't allow for tilde expansion: :ref:config_json_output, :ref:config_lcov_output and :ref:config_run_debug_file. This is now fixed.

  • Wheels are included for 3.14 now that 3.14 rc1 is available.

  • We no longer ship a PyPy-specific wheel. PyPy will install the pure-Python wheel. Closes issue 2001_.

  • In the very unusual situation of not having a current frame, coverage no longer crashes when using the sysmon core, fixing issue 2005_.

  • The "no-ctracer" warning is not issued for Python pre-release versions. Coverage doesn't ship compiled wheels for those versions, so this was far too noisy.

  • On Python 3.14+, the "sysmon" core is now the default if it's supported for your configuration. Plugins and dynamic contexts are still not supported with it.

  • Added a [run] core configuration setting to specify the measurement core, which was previously only available through the COVERAGE_CORE environment variable. Finishes issue 1746_.

  • Fixed incorrect rendering of f-strings with doubled braces, closing issue 1980_.

  • If the C tracer core can't be imported, a warning ("no-ctracer") is issued with the reason.

  • The C tracer core extension module now conforms to PEP 489, closing issue 1977. Thanks, Adam Turner <pull 1978_>_.

  • Added a new source_dirs setting for symmetry with the existing source_pkgs setting. It's preferable to the existing source setting, because you'll get a clear error when directories don't exist. Fixes issue 1942. Thanks, Jeremy Fleischman <pull 1943_>.

  • Fix: the PYTHONSAFEPATH environment variable new in Python 3.11 is properly supported, closing issue 1696. Thanks, Philipp A. <pull 1700_>. This works properly except for a detail when using the coverage command on Windows. There you can use python -m coverage instead if you need exact emulation.

  • The Coverage object has a new method, :meth:.Coverage.branch_stats for getting simple branch information for a module. Closes issue 1888_.

  • The :class:Coverage constructor<.Coverage> now has a plugins parameter for passing in plugin objects directly, thanks to Alex Gaynor <pull 1919_>_.

  • Many constant tests in if statements are now recognized as being optimized away. For example, previously if 13: would have been considered a branch with one path not taken. Now it is understood as always true and no coverage is missing.

  • The experimental sys.monitoring support now works for branch coverage if you are using Python 3.14.0 alpha 6 or newer. This should reduce the overhead coverage.py imposes on your test suite. Set the environment variable COVERAGE_CORE=sysmon to try it out.

  • Confirmed support for PyPy 3.11. Thanks Michał Górny.

  • Fix: some descriptions of missing branches in HTML and LCOV reports were incorrect when multi-line statements were involved (issue 1874_ and issue 1875_). These are now fixed.

  • Fix: Python 3.14 defers evaluation of annotations <pep649_>_ by moving them into separate code objects. That code is rarely executed, so coverage.py would mark them as missing, as reported in issue 1908_. Now they are ignored by coverage automatically.

  • Fixed an obscure and mysterious problem on PyPy 3.10 seemingly involving mocks, imports, and trace functions: issue 1902_. To be honest, I don't understand the problem or the solution, but git bisect helped find it, and now it's fixed.

  • Docs: re-wrote the :ref:subprocess page to put multiprocessing first and to highlight the correct use of :class:multiprocessing.Pool <python:multiprocessing.pool.Pool>.

  • Fix: the LCOV report code assumed that a branch line that took no branches meant that the entire line was unexecuted. This isn't true in a few cases: the line might always raise an exception, or might have been optimized away. Fixes issue 1896_.

  • Fix: similarly, the HTML report will now explain that a line that jumps to none of its expected destinations must have always raised an exception. Previously, it would say something nonsensical like, "line 4 didn't jump to line 5 because line 4 was never true, and it didn't jump to line 7 because line 4 was always true." This was also shown in issue 1896_.

  • Fix: nested matches of exclude patterns could exclude too much code, as reported in issue 1779_. This is now fixed.

  • Changed: previously, coverage.py would consider a module docstring to be an executable statement if it appeared after line 1 in the file, but not executable if it was the first line. Now module docstrings are never counted as executable statements. This can change coverage.py's count of the number of statements in a file, which can slightly change the coverage percentage reported.

  • In the HTML report, the filter term and "hide covered" checkbox settings are remembered between viewings, thanks to Daniel Diniz <pull 1776_>_.

  • Python 3.13.0b1 is supported.

  • Fix: very complex source files like this one <resolvent_lookup_>_ could cause a maximum recursion error when creating an HTML report. This is now fixed, closing issue 1774_.

  • HTML report improvements:

    • Support files (JavaScript and CSS) referenced by the HTML report now have hashes added to their names to ensure updated files are used instead of stale cached copies.

    • Missing branch coverage explanations that said "the condition was never false" now read "the condition was always true" because it's easier to understand.

    • Column sort order is remembered better as you move between the index pages, fixing issue 1766. Thanks, Daniel Diniz <pull 1768_>.

v7.5.0

Compare Source

  • Added initial support for function and class reporting in the HTML report. There are now three index pages which link to each other: files, functions, and classes. Other reports don't yet have this information, but it will be added in the future where it makes sense. Feedback gladly accepted! Finishes issue 780_.

  • Other HTML report improvements:

    • There is now a "hide covered" checkbox to filter out 100% files, finishing issue 1384_.

    • The index page is always sorted by one of its columns, with clearer indications of the sorting.

    • The "previous file" shortcut key didn't work on the index page, but now it does, fixing issue 1765_.

  • The debug output showing which configuration files were tried now shows absolute paths to help diagnose problems where settings aren't taking effect, and is renamed from "attempted_config_files" to the more logical "config_files_attempted."

  • Python 3.13.0a6 is supported.

v7.4.4

Compare Source

  • Fix: in some cases, even with [run] relative_files=True, a data file could be created with absolute path names. When combined with other relative data files, it was random whether the absolute file names would be made relative or not. If they weren't, then a file would be listed twice in reports, as detailed in issue 1752_. This is now fixed: absolute file names are always made relative when combining. Thanks to Bruno Rodrigues dos Santos for support.

  • Fix: the last case of a match/case statement had an incorrect message if the branch was missed. It said the pattern never matched, when actually the branch is missed if the last case always matched.

  • Fix: clicking a line number in the HTML report now positions more accurately.

  • Fix: the report:format setting was defined as a boolean, but should be a string. Thanks, Tanaydin Sirin <pull 1754_>_. It is also now documented on the :ref:configuration page <config_report_format>.

v7.4.3

  • Fix: in some cases, coverage could fail with a RuntimeError: "Set changed size during iteration." This is now fixed, closing issue 1733_.

v7.4.2

Compare Source

  • Fix: setting COVERAGE_CORE=sysmon no longer errors on 3.11 and lower, thanks Hugo van Kemenade <pull 1747_>_. It now issues a warning that sys.monitoring is not available and falls back to the default core instead.

v7.4.1

  • Python 3.13.0a3 is supported.

  • Fix: the JSON report now includes an explicit format version number, closing issue 1732_.

v7.4.0

Compare Source

  • In Python 3.12 and above, you can try an experimental core based on the new :mod:sys.monitoring <python:sys.monitoring> module by defining a COVERAGE_CORE=sysmon environment variable. This should be faster for line coverage, but not for branch coverage, and plugins and dynamic contexts are not yet supported with it. I am very interested to hear how it works (or doesn't!) for you.

v7.3.4

Compare Source

  • Fix: the change for multi-line signature exclusions in 7.3.3 broke other forms of nested clauses being excluded properly. This is now fixed, closing issue 1713_.

  • Fix: in the HTML report, selecting code for copying won't select the line numbers also. Thanks, Robert Harris <pull 1717_>_.

v7.3.3

Compare Source

  • Fix: function definitions with multi-line signatures can now be excluded by matching any of the lines, closing issue 684. Thanks, Jan Rusak, Maciej Kowalczyk and Joanna Ejzel <pull 1705_>.

  • Fix: XML reports could fail with a TypeError if files had numeric components that were duplicates except for leading zeroes, like file1.py and file001.py. Fixes issue 1709_.

  • The coverage annotate command used to announce that it would be removed in a future version. Enough people got in touch to say that they use it, so it will stay. Don't expect it to keep up with other new features though.

  • Added new :ref:debug options <cmd_run_debug>:

    • pytest writes the pytest test name into the debug output.

    • dataop2 writes the full data being added to CoverageData objects.

v7.3.2

  • The coverage lcov command ignored the [report] exclude_lines and [report] exclude_also settings (issue 1684). This is now fixed, thanks Jacqueline Lee <pull 1685_>.

  • Sometimes SQLite will create journal files alongside the coverage.py database files. These are ephemeral, but could be mistakenly included when combining data files. Now they are always ignored, fixing issue 1605_. Thanks to Brad Smith for suggesting fixes and providing detailed debugging.

  • On Python 3.12+, we now disable SQLite writing journal files, which should be a little faster.

  • The new 3.12 soft keyword type is properly bolded in HTML reports.

  • Removed the "fullcoverage" feature used by CPython to measure the coverage of early-imported standard library modules. CPython stopped using it <88054_>_ in 2021, and it stopped working completely in Python 3.13.

v7.3.1

Compare Source

  • The semantics of stars in file patterns has been clarified in the docs. A leading or trailing star matches any number of path components, like a double star would. This is different than the behavior of a star in the middle of a pattern. This discrepancy was identified by Sviatoslav Sydorenko <starbad_>, who provided patient detailed diagnosis <pull 1650_> and graciously agreed to a pragmatic resolution.

  • The API docs were missing from the last version. They are now restored <apidocs_>_.

v7.3.0

Compare Source

  • Added a :meth:.Coverage.collect context manager to start and stop coverage data collection.

  • Dropped support for Python 3.7.

  • Fix: in unusual circumstances, SQLite cannot be set to asynchronous mode. Coverage.py would fail with the error Safety level may not be changed inside a transaction. This is now avoided, closing issue 1646_. Thanks to Michael Bell for the detailed bug report.

  • Docs: examples of configuration files now include separate examples for the different syntaxes: .coveragerc, pyproject.toml, setup.cfg, and tox.ini.

  • Fix: added nosemgrep comments to our JavaScript code so that semgrep-based SAST security checks won't raise false alarms about security problems that aren't problems.

  • Added a CITATION.cff file, thanks to Ken Schackart <pull 1641_>_.

v7.2.7

Compare Source

  • Fix: reverted a change from 6.4.3 <pull 1347b_>_ that helped Cython, but also increased the size of data files when using dynamic contexts, as described in the now-fixed issue 1586. The problem is now avoided due to a recent change (issue 1538 <issue 1538b_>). Thanks to Anders Kaseorg <pull 1629_>_ and David Szotten for persisting with problem reports and detailed diagnoses.

  • Wheels are now provided for CPython 3.12.

v7.2.6

Compare Source

  • Fix: the lcov command could raise an IndexError exception if a file is translated to Python but then executed under its own name. Jinja2 does this when rendering templates. Fixes issue 1553_.

  • Python 3.12 beta 1 now inlines comprehensions. Previously they were compiled as invisible functions and coverage.py would warn you if they weren't completely executed. This no longer happens under Python 3.12.

  • Fix: the coverage debug sys command includes some environment variables in its output. This could have included sensitive data. Those values are now hidden with asterisks, closing issue 1628_.
