7.6.10

Version 7.6.10 — 2024-12-26

• 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 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 Measuring subprocesses page to put multiprocessing first and to highlight the correct use of https://docs.python.org/3/library/multiprocessing.html#multiprocessing.pool.Pool.

7.6.9

Version 7.6.9 — 2024-12-06

• Fix: Tomas Uribe fixed a performance problem in the XML report. Large code bases should produce XML reports much faster now.

7.6.8

Version 7.6.8 — 2024-11-23

• 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.

7.6.7

Version 7.6.7 — 2024-11-15

• Fix: ugh, the other assert from 7.6.5 can also be encountered in the wild, so it’s been restored to a conditional. Sorry for the churn.

7.6.6

Version 7.6.6 — 2024-11-15

• One of the new asserts from 7.6.5 caused problems in real projects, as reported in issue 1891. The assert has been removed.

7.6.5

Version 7.6.5 — 2024-11-14

• Fix: fine-tuned the exact Python version (3.12.6) when exiting from with statements changed how they traced. This affected whether people saw the fix for issue 1880.
• Fix: isolate our code more from mocking in the os module that in rare cases can cause bizarre behavior.
• Refactor: some code unreachable code paths in parser.py were changed to asserts. If you encounter any of these, please let me know!

7.6.4

Version 7.6.4 — 2024-10-20

• Fix: multi-line with statements could cause contained branches to be incorrectly marked as missing (issue 1880). This is now fixed.

7.6.3

Version 7.6.3 — 2024-10-13

• Fix: nested context managers could incorrectly be analyzed to flag a missing branch on the last context manager, as described in issue 1876. This is now fixed.
• Fix: the missing branch message about not exiting a module had an extra “didn’t,” as described in issue 1873. This is now fixed.

7.6.2

Version 7.6.2 — 2024-10-09

• 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. Closes issue 1852.
• 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.
• 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 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 1849 and pull 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.

7.6.1

Version 7.6.1 — 2024-08-04

• Fix: coverage used to fail when measuring code using https://docs.python.org/3/library/runpy.html#runpy.run_path with a https://docs.python.org/3/library/pathlib.html#pathlib.Path argument. This is now fixed, thanks to Ask Hjorth Larsen.
• Fix: backslashes preceding a multi-line backslashed string could confuse the HTML report. This is now fixed, thanks to LiuYinCarl.
• Now we publish wheels for Python 3.13, both regular and free-threaded.
