* [3.13] gh-129346: Handle allocation errors for SQLite aggregate context ↵Miss Islington (bot)2025-01-271-0/+5
| | | | | | | (GH-129347) (#129372) (cherry picked from commit 379ab856f59423c570333403a7d5d72f3ea82d52) Co-authored-by: Erlend E. Aasland <erlend@python.org>
* gh-118406: Add signature for sqlite3.Connection objects (#118428)Erlend E. Aasland2024-04-301-0/+7

* gh-111926: Make weakrefs thread-safe in free-threaded builds (#117168)mpage2024-04-081-2/+2
| | | | | | | | | Most mutable data is protected by a striped lock that is keyed on the referenced object's address. The weakref's hash is protected using the weakref's per-object lock. Note that this only affects free-threaded builds. Apart from some minor refactoring, the added code is all either gated by `ifdef`s or is a no-op (e.g. `Py_BEGIN_CRITICAL_SECTION`).

Users of the sqlite3 module are not responsible for using the SQLite C API correctly. * Don't overwrite BufferError with ValueError when conversion to BLOB fails. * Raise ProgrammingError instead of Warning if user tries to execute() more than one SQL statement. * Raise ProgrammingError instead of ValueError if an SQL query contains null characters. * Make sure `_pysqlite_set_result` raises an exception if it returns -1.

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541
