Hi
Consider a 'send' method that sends a message to another system via a socket.
This method will wait for a response before returning. There are two possible
error conditions:
1) Timeout - i.e. no response received
2) Illegal response received
I need to communicate these errors to the caller of send(). So far I have just
raised a RuntimeError exception for both errors, and stated what happened like
this:
raise RuntimeError("Message timeout")
That's fine if the caller just wants to print the error but not so good if the
code needs to act differently according to which error condition occurred.
So, my question is, what's the pythonic way of doing this? Should I subclass
RuntimeError for each possible error condition? E.g.:
class MessageTimeoutError(RuntimeError): pass
class IllegalResponseError(RuntimeError): pass
Best regards
David
