These functions are broken by design because they discard any exceptions raised
inside, including MemoryError and KeyboardInterrupt. They should not be
used in new code.
* PyDict_GetItem() and PyObject_HasAttr() suppress arbitrary errors and
should not be used.
* PyUnicode_CompareWithASCIIString() only works if the second argument
is ASCII string.
* Refleak in get_suggestions_for_name_error.
* Use of borrowed pointer after possible freeing (self).
* Add some missing error checks.
Remove _PyWeakref_GetWeakrefCount() and _PyWeakref_ClearRef() from
the public C API: move them to the internal C API.
Refactor also _weakref_getweakrefs() code to make it more readable.
It now raises an exception if sys.modules doesn't hold a strong
reference to the module.
Elaborate the comment explaining why a weak reference is used to
create a borrowed reference.
* Replace PyWeakref_GET_OBJECT() with _PyWeakref_GET_REF().
* _sqlite/blob.c now holds a strong reference to the blob object
while calling close_blob().
* _xidregistry_find_type() now holds a strong reference to registered
while using it.
* Add _PyWeakref_IS_DEAD() internal function.
* Modify is_dead_weakref() of Modules/_weakref.c and
_pysqlite_drop_unused_cursor_references() to replace
PyWeakref_GET_OBJECT() with _PyWeakref_IS_DEAD().
* Replace "int i" with "Py_ssize_t i" to iterate on cursors
in _pysqlite_drop_unused_cursor_references().
This new exception type is raised instead of `NotImplementedError` when
a path operation is not supported. It can be raised from `Path.readlink()`,
`symlink_to()`, `hardlink_to()`, `owner()` and `group()`. In a future
version of pathlib, it will be raised by `AbstractPath` for these methods
and others, such as `AbstractPath.mkdir()` and `unlink()`.
finalize_modules_clear_weaklist() now holds a strong reference to the
module longer than before: replace PyWeakref_GET_OBJECT() with
_PyWeakref_GET_REF().
Rename PyDict_GetItemProxy() to _PyDict_GetItemProxy() and mark it as
static. _PyDict_GetItemProxy() now returns a strong reference,
instead of a borrowed reference: replace PyWeakref_GET_OBJECT() with
_PyWeakref_GET_REF().
Hold a strong reference on the object, rather than using a borrowed reference:
replace PyWeakref_GET_OBJECT() with PyWeakref_GetRef() and
_PyWeakref_GET_REF().
Remove assert(PyWeakref_CheckRef(localweakref)) since it's already
tested by _PyWeakref_GET_REF().
* Add tests on PyImport_AddModuleRef(), PyImport_AddModule() and
PyImport_AddModuleObject().
* pythonrun.c: Replace Py_XNewRef(PyImport_AddModule(name)) with
PyImport_AddModuleRef(name).
* Rename proxy_checkref() to proxy_check_ref().
* proxy_check_ref() now checks the object, not the proxy.
* Most functions take PyObject* instead of PyWeakReference*.
* Remove redundant calls to PyWeakref_GET_OBJECT().
Refactor PyRun_InteractiveOneObjectEx(), _PyRun_SimpleFileObject()
and PyRun_SimpleStringFlags():
* Keep a strong reference to the __main__ module while using its
dictionary (PyModule_GetDict()). Use PyImport_AddModule() with
Py_XNewRef().
* Declare variables closer to where they are defined.
* Rename variables to use name longer than 1 character.
* Add pyrun_one_parse_ast() sub-function.
