[issue26198] PyArg_ParseTuple with format "et#" and "es#" detects overflow by raising TypeError instead of ValueError

[Hrvoje Nikšić]

Hrvoje Nikšić added the comment:

The problem can be encountered and easily reproduced by calling os.path functions, such as os.path.abspath, with a sufficiently large string on Windows:

>>> os.path.abspath("a" * 1024)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "P:\...\lib\ntpath.py", line 471, in abspath
TypeError: must be (buffer overflow), not str

The error message is somewhat confusing, making it look like the "must be" and "not" arguments are swapped. Ideally, the message could be along the lines of "must be a string of no more than X characters".
