Hello, Short story: bytearray and array.array by construction allow user code to reallocate their internal memory buffer. But a raw pointer to the said buffer can also be obtained by another thread, and used after releasing the GIL (for CPU-intensive operations like compression). As a consequence, the interpreter crashes.
Was it envisioned? I see no warning in the docs for the array.array type (although it has been there for quite some time). See http://bugs.python.org/issue3139 (reported by Amaury) Regards Antoine. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
