Mark Dickinson 02515f7a3a Minor consistency fixes for some longobject.c exception messages: 
- replace 'long int' / 'long' by 'int'
 - fix capitalization of "Python" in PyLong_AsUnsignedLong
 - "is too large" -> "too large", for consistency with other messages.

Victor Stinner 5b3b1006bb Issue #18520: Fix _PyDict_GetItemId(), suppress _PyUnicode_FromId() error 
As PyDict_GetItem(), _PyDict_GetItemId() suppresses all errors that may occur,
for historical reasons.

Victor Stinner 1c8f059019 Issue #18520: Add a new PyStructSequence_InitType2() function, same than 
PyStructSequence_InitType() except that it has a return value (0 on success,
-1 on error).

 * PyStructSequence_InitType2() now raises MemoryError on memory allocation failure
 * Fix also some calls to PyDict_SetItemString(): handle error

Victor Stinner 2c40f640d9 Issue #18408: Fix list_ass_slice(), handle list_resize() failure 
I tested the patch manually by injecting a fault using gdb: list items are
correctly restored on failure.

Victor Stinner 8e47832737 Issue #18408: PyObject_Str(), PyObject_Repr() and type_call() now fail with an 
assertion error if they are called with an exception set (PyErr_Occurred()).

As PyEval_EvalFrameEx(), they may clear the current exception and so the caller
looses its exception.

Victor Stinner f97dfd7b59 Issue #18408: Fix dict_repr(), don't call PyObject_Repr() with an exception set 
PyObject_Repr() can removes the current exception. For example, module_repr()
calls PyErr_Clear() if calling loader.module_repr(mod) failed.

Victor Stinner 26f91999b4 Close #18469: Replace PyDict_GetItemString() with _PyDict_GetItemId() in structseq.c 
_PyDict_GetItemId() is more efficient: it only builds the Unicode string once.
Identifiers (dictionary keys) are now created at Python initialization, and if
the creation failed, Python does exit with a fatal error.

Before, PyDict_GetItemString() failure was not handled: structseq_new() could
call PyObject_GC_NewVar() with a negative size, and structseq_dealloc() could
also crash.

Victor Stinner 3997cfdb7f Cleanup type_call() to ease debug 
It was easy to miss the call to type->tp_init because it was done in a long
conditional expression. Split the long expression in multiple lines to make the
debug step by step easier.

Victor Stinner 53510cda59 Issue #18408: type_new() and PyType_FromSpecWithBases() now raise MemoryError

Victor Stinner e699e5a218 Issue #18408: Don't check unicode consistency in _PyUnicode_HAS_UTF8_MEMORY() 
and _PyUnicode_HAS_WSTR_MEMORY() macros

These macros are called in unicode_dealloc(), whereas the unicode object can be
"inconsistent" if the creation of the object failed.

For example, when unicode_subtype_new() fails on a memory allocation,
_PyUnicode_CheckConsistency() fails with an assertion error because data is
NULL.

Victor Stinner 3de5869864 Issue #18408: PyObject_Call() now fails with an assertion error in debug mode 
if the function called failed whereas no exception was raised, to detect bugs
earlier.

Victor Stinner a41f085144 Issue #18408: pmerge() help of mro_implementation() now raises MemoryError on 
memory allocation failure

Replace also PyMem_Free() with PyMem_FREE() to be consistent with the rest of
the function.

Victor Stinner 9035ad932b Issue #18408: In debug mode, PyCFunction_Call() now checks if an exception was 
raised if the result is NULL to help to find bugs in C mode (get the error
earlier than the SystemError in ceval.c).

Victor Stinner 2e8474ddde Issue #18408: slot_tp_str() must not fallback on slot_tp_repr() on error 
type->tp_str must not point to slot_tp_str() if type has no __str__ attribute,
so there is no reason for slot_tp_str() to fallback on slot_tp_str() on lookup
error. Moreover, calling PyErr_Clear() may hide a real bug like MemoryError.

If __str__ attribute is removed, slots must be updated (which is done by
type_setattro()).

Victor Stinner 54e4ca76c9 typeobject.c: remove trailing spaces 2013-07-11 22:42:25 +02:00
Victor Stinner c4266360fc Issue #18408: Fix _PyMem_DebugRealloc() 
Don't mark old extra memory dead before calling realloc(). realloc() can fail
and realloc() must not touch the original buffer on failure.

So mark old extra memory dead only on success if the new buffer did not move
(has the same address).

Victor Stinner 9e6b4d715c Issue #18408: _PyUnicodeWriter_Finish() now clears its buffer attribute in all
