v7.6.2

Compare Source

• Dropped support for Python 3.8 and PyPy 3.8.

• Fix: a final wildcard match/case clause assigning to a name (case _ as value) was incorrectly marked as a missing branch. This is now fixed,
  closing issue 1860_.

• Fewer things are considered branches now. Lambdas, comprehensions, and
  generator expressions are no longer marked as missing branches if they don't
  complete execution.

• Fix: the HTML report didn't properly show multi-line f-strings that end with
  a backslash continuation. This is now fixed, closing issue 1836, thanks
  to LiuYinCarl and Marco Ricci <pull 1838_>.

• Fix: the LCOV report now has correct line numbers (fixing issue 1846) and better branch descriptions for BRDA records (fixing issue 1850_). There are other changes to lcov also, including a new configuration option :ref:line_checksums <config_lcov_line_checksums> to control whether line checksums are included in the lcov report. The default is false. To keep checksums set it to true. All this work is thanks to Zack Weinberg (pull 1849andpull 1851`_).

• Fixed the docs for multi-line regex exclusions, closing issue 1863_.

• Fixed a potential crash in the C tracer, closing issue 1835, thanks to
  Jan Kühle <pull 1843_>.

v7.6.1

• Fix: coverage used to fail when measuring code using :func:runpy.run_path <python:runpy.run_path> with a :class:Path <python:pathlib.Path> argument.
  This is now fixed, thanks to Ask Hjorth Larsen <pull 1819_>_.

• Fix: backslashes preceding a multi-line backslashed string could confuse the
  HTML report. This is now fixed, thanks to LiuYinCarl <pull 1828_>_.

• Now we publish wheels for Python 3.13, both regular and free-threaded.

• Exclusion patterns can now be multi-line, thanks to Daniel Diniz <pull 1807_>. This enables many interesting exclusion use-cases, including those
  requested in issues 118 <issue 118_> (entire files), 996 <issue 996_>_ (multiple lines only when appearing together), 1741 <issue 1741_>_ (remainder of a function), and 1803 <issue 1803_>_
  (arbitrary sequence of marked lines). See the :ref:multi_line_exclude
  section of the docs for more details and examples.

• The JSON report now includes per-function and per-class coverage information.
  Thanks to Daniel Diniz <pull 1809_>_ for getting the work started. This
  closes issue 1793_ and issue 1532_.

• Fixed an incorrect calculation of "(no class)" lines in the HTML classes
  report.

• Python 3.13.0b3 is supported.

v7.5.4

• If you attempt to combine statement coverage data with branch coverage data,
  coverage.py used to fail with the message "Can't combine arc data with line
  data" or its reverse, "Can't combine line data with arc data." These
  messages used internal terminology, making it hard for people to understand
  the problem. They are now changed to mention "branch coverage data" and
  "statement coverage data."

• Fixed a minor branch coverage problem with wildcard match/case cases using
  names or guard clauses.

• Started testing on 3.13 free-threading (nogil) builds of Python. I'm not
  claiming full support yet. Closes issue 1799_.

• Performance improvements for combining data files, especially when measuring
  line coverage. A few different quadratic behaviors were eliminated. In one
  extreme case of combining 700+ data files, the time dropped from more than
  three hours to seven minutes. Thanks for Kraken Tech for funding the fix.

• Performance improvements for generating HTML reports, with a side benefit of
  reducing memory use, closing issue 1791_. Thanks to Daniel Diniz for
  helping to diagnose the problem.

v7.5.2

Compare Source

• 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: parsing error handling is improved to ensure bizarre source files are
  handled gracefully, and to unblock oss-fuzz fuzzing, thanks to Liam DeVoe <pull 1788_>. Closes issue 1787.
