New submission from STINNER Victor <[email protected]>:
b'abc'.partition(':') raises a confusing TypeError('expected an object with the
buffer interface'): what is a buffer? what is the buffer interface?
The error comes from PyObject_AsCharBuffer() which is used by:
- bytes methods: partition, rpartition, find, index, rfind, rindex, count,
translate, replace, startswith, endswith
- complex(): raise a better but incomplete error message on error ("complex()
arg is not a string"), incomplete because number is not mentionned
- float(): raise a better error message on error ("float() argument must be a
string or a number")
- PyArg_Parse*() with the "e" format -> posix.spawnvpe(), imp.load_compiled(),
imp.load_source(), imp.load_package()
The error message should be changed to something mentioning classic Python
terms. Eg. TypeError("expected bytes, bytearray or buffer compatible object").
