[dependabot]

Bumps coverage from 7.13.5 to 7.15.2.

Release notes

Sourced from coverage's releases.

7.15.2

Version 7.15.2 — 2026-07-15

• Fix: one of the performance improvements in 7.15.1 (pull 2215) dramatically increased memory use during reporting for large projects. Now we use a different approach that is both faster and slimmer than 7.15.0. Fixes issue 2229.

7.15.1

Version 7.15.1 — 2026-07-12

• Fix: in the HTML report with show_contexts enabled, a context label containing </script> (for example a parametrized pytest node id) could close the inline <script> element in a file page early, injecting markup. Context labels are now fully escaped. Thanks, Rajath Mohare.
• A number of performance improvements thanks to Paul Kehrer, in pull requests 2213, 2214, 2215, 2216, 2218, 2220, and 2221.

7.15.0

Version 7.15.0 — 2026-07-02

• Since 7.14.0, reporting commands implicitly combine parallel data files. Now those commands have a new option --keep-combined to retain the data files after combining them instead of the default, which is to delete them. Finishes issue 2198.
• Fix: the LCOV report would incorrectly count excluded functions as uncovered, as described in issue 2205. This is now fixed thanks to Martin Kuntz Jacobsen.
• When running your program, coverage now correctly sets yourmodule.__spec__.loader as strongly recommended, avoiding the deprecation warning described in issue 2208. Thanks, A5rocks.
• Fix: with Python 3.10, running with the -I (isolated mode) option didn’t correctly omit the current directory from the module search path, as described in issue 2103. That is now fixed thanks to Ilia Sorokin.

7.14.3

Version 7.14.3 — 2026-06-22

• Fix: the default ... exclusion rule now also matches function bodies whose closing return-type bracket is on its own line (for example, after a long -> dict[ ... ] annotation that a formatter has split over multiple lines). Closes issue 2185, thanks Mengjia Shang.
• Fix: On 3.13t, we incorrectly issued Couldn't import C tracer errors. We can’t import the C tracer because in 7.14.2 we stopped shipping compiled wheels for 3.13t. Thanks, Hugo van Kemenade.

7.14.2

Version 7.14.2 — 2026-06-20

• Fix: some messages were being written to stdout, making coverage json -o - useless for capturing JSON output. Now messages are written to stderr, fixing issue 2197.
• Fix: CoverageData kept one SQLite connection per thread that recorded coverage, but never closed them when those threads terminated. On long runs with many short-lived threads this leaked one file descriptor per dead thread, eventually failing with OSError: [Errno 24] Too many open files. Connections belonging to terminated threads are now closed and dropped. Fixes issue 2192. Thanks, Matthew Lloyd.
• Fix: when using sys.monitoring, we were assuming we could use the COVERAGE_ID tool id. But other tools might also assume they could use that id. Pre-allocated ids don’t really make sense, so now we search for a usable one instead. Fixes issue 2187.
• Following the advice of cibuildwheel, we no longer distribute wheels for Python 3.13 free-threaded.
