The refleak buildbots have detected that test_type_comments is leaking references. Example failure: https://buildbot.python.org/all/#/builders/1/builds/490/steps/4/logs/stdio test_type_comments leaked [37, 37, 37] references, sum=111 test_type_comments leaked [11, 12, 11] memory blocks, sum=34 1 test failed again: test_type_comments Bisecting shows that PR11645 is the one that introduced the refleaks: https://github.com/python/cpython/pull/11645/files# After some hours of debugging, I have identified the (possible) cause of the majority of the refleaks. The type_comments created in ast.c with new_type_comment() never reaches 0 reference counts. This **seems** to be because the cleanup for the stmt_ty elements where the type_comments are included never call DECREF on these elements when destroyed unless I am missing something fundamental. |
