Suppose you have tow sockets handled by two asynchat.async_chat class
instances and from class1 you want to send some data through class2:

   def mymethod(self):

Since push_with_producer automatically calls initiate_send() if an error
occurs while class2 reads the first chunk of data from the producer,
class1's handle_error gets called.
If the error occurs when reading the next chunks of data class2's
handle_error will be called instead.
This is an inconsistency that should be fixed so that always class2's
handle_error gets called.

The patch in attachment does that.

The idea is good, but seems that error handling should be inlined into initiate_send.

Also those 3 special exceptions should be defined once in the module instead of repeating them.

This issue is 6 years old. I don't understand the bug and the patch has no unit test. I suggest to close the issue as out of date. The asynchat module is now deprecated in favor of the new shiny asyncio module.

#6550 and #11267 have been closed as out of date as asynchat and asyncore are effectively deprecated in favour of asyncio so can't this go the same way?
