[PATCH libnbd v2] python: Raise a custom exception containing error string and errno.
This kind of fixes the problems in v1. The exception still primarily lives in the libnbdmod and you could still refer to it using libnbdmod.Error (but don't do that). However when the exception is printed it now appears as nbd.Error, and you can catch it also using the same name. Other problems: - There is no "nice" interface to accessing the exception fields. You have to use

[PATCH libnbd] python: Raise a custom exception containing error string and errno.
I spent a good few hours this morning trying to make this work and came up with the following patch. It's not quite right though. The exception I've created exists in the libnbdmod module (ie. the underlying C module that we use for the Python bindings). Ideally we'd define and throw an exception from the normal nbd module, but I couldn't work out how to do that. Probably

[PATCH libnbd v3] python: Raise a custom exception containing error string and errno.
Following Eric's suggestions from v2, this adds .string, .errno and .__str__ properties. The .string property returns the error string. The .errno property returns the errno (from the errno module), or None. The __str__ property makes the exception nicely printable. Rich.
