coverage 7.17.3

on Python PyPI

Version 7.17.3 — 2026-11-11

• Fix: using patch = fork, a child process wasn’t measured unless patch = subprocess was also used, as described in issue 2340. This is now fixed in pull 2342.
• Fix: the JSON report keys functions and classes by name, but names can repeat, for example a property getter and setter. Only the last one was kept, so the others were missing from the report. Now repeated names get a @<line number> suffix, as in the LCOV report. pull 2353.
• Fix: when combining parallel data files, a file that disappears after it has been listed (for example, when the process writing it is still finishing its write) is now reported with a warning, instead of stopping the combine with a DataError. This was a regression in 7.17.1. Closes issue 2364.
• Fix: with patch = subprocess on Python 3.13, a measured subprocess that was stopped with SIGINT would exit with status 1 instead of dying from the signal. This was a regression in 7.17.1, and is now fixed, closing issue 2362.
• Performance: on Python 3.13 and later, using the C tracer should result in test suites running about 8% to 12% faster (pull 2371).
