| | | | | | | | | | | | (GH-106226) * EOFError no longer overrides other errors such as MemoryError or OSError at the start of the object. * Raise more relevant error when the NULL object occurs as a code object component. * Minimize an overhead of calling PyErr_Occurred().

| | | | | | | | | | (#106041) [3.12] gh-106033: Get rid of new occurrences of PyDict_GetItem and PyObject_HasAttr (GH-106034) These functions are broken by design because they discard any exceptions raised inside, including MemoryError and KeyboardInterrupt.

* [3.12] gh-105699: Use a Thread-Local Variable for PKGCONTEXT (gh-105740) ↵Miss Islington (bot)2023-06-141-0/+15
| | | | | | | | (gh-105765) This fixes a race during import. The existing _PyRuntimeState.imports.pkgcontext is shared between interpreters, and occasionally this would cause a crash when multiple interpreters were importing extensions modules at the same time. To solve this we add a thread-local variable for the value. We also leave the existing state (and infrequent race) in place for platforms that do not support thread-local variables.

* gh-102856: Python tokenizer implementation for PEP 701 (#104323)Marta Gómez Macías2023-05-212-22/+140
| | | | | | | | | | | This commit replaces the Python implementation of the tokenize module with an implementation that reuses the real C tokenizer via a private extension module. The tokenize module now implements a compatibility layer that transforms tokens from the C tokenizer into Python tokenize tokens for backward compatibility. As the C tokenizer does not emit some tokens that the Python tokenizer provides (such as comments and non-semantic newlines), a new special mode has been added to the C tokenizer mode that currently is only used via the extension module that exposes it to the Python layer. This new mode forces the C tokenizer to emit these new extra tokens and add the appropriate metadata that is needed to match the old Python implementation.
