Definitely related to this change in Python 3.3:
Accessing a memoryview element with format ‘B’ (unsigned bytes) now
returns an integer (in accordance with the struct module syntax).
For returning a bytes object the view must be cast to ‘c’ first.
The object returned by PyBuffer_FillInfo is 'B' format: this means that python code finds itself dealing in Py 3.3 with a different object respect to what returned in Py 3.1 and 3.2. Is this change in the behavior wanted? Wouldn't have been better having FillInfo return a 'c' buffer instead?
I'm adding support to Py 3.3 to psycopg2 and the B buffers make the test suite fail. I want psycopg to return consistent objects across 3.x. Is the change in this commit correct?

Is this a good way to return a 'c' buffer? |
