Core and builtins ----------------- +- Bug #1055820 Cyclic garbage collection was not protecting against that + calling a live weakref to a piece of cyclic trash could resurrect an + insane mutation of the trash if any Python code ran during gc (via + running a dead object's __del__ method, running another callback on a + weakref to a dead object, or via any Python code run in any other thread + that managed to obtain the GIL while a __del__ or callback was running + in the thread doing gc). The most likely symptom was "impossible" + ``AttributeEror`` exceptions, appearing seemingly at random, on weakly + referenced objects. The cure was to clear all weakrefs to unreachable + objects before allowing any callbacks to run. + - Bug #1054139 _PyString_Resize() now invalidates its cached hash value. Extension Modules |
