New submission from STINNER Victor <vstin...@python.org>:
In September 2019, the _ast extension module was converted to PEP 384 (stable ABI): bpo-38113. In bpo-41631, I moved the _ast module state back to a global state, rather than a regular module state, to fix multiple bugs. The state should be made per intepreter (moved into PyInterpreterState). Also, each interpreter should have its own _ast types (_ast.AST, _ast.Constant, etc.), rather than sharing all types. Hopefully, in 3.9, _ast types have been converted to heap types. To fix bpo-41631, I wanted to convert _ast.AST heap type back into a static type, to prevenet a subinterpreter to modify it, but Petr Viktorin asked me to leave it as it is: https://github.com/python/cpython/pull/21961#issuecomment-685821519 I agree since I would like to convert all static types to heap types: bpo-40077. ---------- components: Interpreter Core messages: 376983 nosy: vstinner priority: normal severity: normal status: open title: _ast module state should be made per interpreter versions: Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41796> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
