Sorry, something went wrong.
pythonGH-156406) PEP 829 moved .pth handling from site.addpackage() into StartupState._exec_imports(), and the local holding the path of the .pth file being processed was renamed from 'fullname' to 'filename'. Import lines in .pth files generated before Python 3.15 read that local, so they now fail with NameError on every interpreter startup. Inject 'fullname' into the frame which executes pth code, next to the 'sitedir' shim added for pythongh-149671. Reported downstream as karellen/wheel-axle#38 (cherry picked from commit 7f3d09b6e8018c3710dfde9f71c63d47a047beb1) Co-authored-by: Arcadiy Ivanov <arcadiy@ivanov.biz> Co-authored-by: Barry Warsaw <barry@python.org>

Import lines in .pth files generated before Python 3.15 read that
