Victor Stinner ad14ccd047 Issue #19512: add _PyUnicode_CompareWithId() function
_PyUnicode_CompareWithId() is faster than PyUnicode_CompareWithASCIIString()
when both strings are equal and interned.

Add also _PyId_builtins identifier for "builtins" common string.

Victor Stinner 090543736f Issue #19512: add some common identifiers to only create common strings once,
instead of creating temporary Unicode string objects

Add also more identifiers in pythonrun.c to avoid temporary Unicode string
objets for the interactive interpreter.

Victor Stinner c82bfd871f Issue #18664, #18408: Rewrite PyErr_WriteUnraisable() to handle errors
* Catch PyFile_WriteString() and PyFile_WriteObject() errors
 * Clear the current exception on _PyObject_GetAttrId() failure
 * Use PyUnicode_CompareWithASCIIString() and PyFile_WriteObject() instead of
   _PyUnicode_AsString() and strcmp() to avoid Unicode encoding error. stderr
   has a more tolerant error handler than utf-8/strict.

Victor Stinner f54a574478 Issue #18520: PyErr_NoMemory() now fails with a fatal error if it is called

Victor Stinner ace47d7efd Issue #18408: PyEval_EvalFrameEx() and PyEval_CallObjectWithKeywords() now fail
with an assertion error if they are called with an exception set
(PyErr_Occurred()).

If these functions are called with an exception set, the exception may be
cleared and so the caller looses its exception.

Add also assertions to PyEval_CallObjectWithKeywords() and call_function() to
check if the function succeed with no exception set, or the function failed
with an exception set.

Brett Cannon 82da8886cc Issue #15767: Revert 3a50025f1900 for ModuleNotFoundError 2013-07-04 17:48:16 -04:00
Brett Cannon 8f5ac5106e Issue #15767: Touch up ModuleNotFoundError usage by import.
Forgot to raise ModuleNotFoundError when None is found in sys.modules.
This led to introducing the C function PyErr_SetImportErrorSubclass()
to make setting ModuleNotFoundError easier.

Also updated the reference docs to mention ModuleNotFoundError
appropriately. Updated the docs for ModuleNotFoundError to mention the
None in sys.modules case.

Lastly, it was noticed that PyErr_SetImportError() was not setting an
exception when returning None in one case. That issue is now fixed.

Add INCREFs, fix args->kwargs, and a second args==NULL check was removed,
left over from a merger with another function. Instead, checking msg==NULL
does what that used to do in a roundabout way.

Jeffrey Yasskin 8e0bdfd1d4 Make PyErr_Occurred return NULL if there is no current thread. Previously it
would Py_FatalError, which called PyErr_Occurred, resulting in a semi-infinite
recursion.

Fixes issue 3605.

Amaury Forgeot d'Arc db26f7c137 Issue 3611: in some cases (a __del__ re-raising an exception, when called from inside
an 'except' clause), the exception __context__ would be reset to None.
This crases the interpreter if this precisely happens inside PyErr_SetObject.

- now the __context__ is properly preserved
- in any case, PyErr_SetObject now saves the current exc_value in a local variable, to
avoid such crashes in the future.

Reviewer: Antoine Pitrou.

Antoine Pitrou ec569b7947 Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
mechanism. In the process, fix a bug where isinstance() and issubclass(),
when given a tuple of classes as second argument, were looking up
__instancecheck__ / __subclasscheck__ on the tuple rather than on each
type object.
