Version 7.10.3 — 2025-08-10

• 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_.
