[issue40842] _Pickler_CommitFrame() always returns 0 but it's return code is checked

New submission from Rémi Lapeyre : I'm currently investigating a SystemError one of our workers returned: returned NULL without setting an error While doing so I came across the _Pickler_CommitFrame() function: static int _Pickler_CommitFrame(PicklerObject *self) { size_t frame_len

[issue40403] pdb does not drop into debugger upon SyntaxError caused by ast.literal_eval

Rémi Lapeyre added the comment: Thanks, I was wondering about that. I didn't know what is the status of the function exactly and found https://bugs.python.org/msg344080. While they are not documented, you can find them in dir() and in the help, maybe they should have a docstring

[issue27580] CSV Null Byte Error

Rémi Lapeyre added the comment: Writing to those files is obviously as easy, since like you said "because by it's very nature it's non-printable" and you will probably not find it in your data: with open('file', 'w') as f: f.write('\x00'.join(data)) It will break if there
