Proposal: reactor.clientTCP accepts a protocol factory instead of a protocol, and only makes a protocol instance if connection was made. Additionally, it accepts an additional argument, failureCallback, which will get called with a status code (CONNECTION_REFUSED, NO_SUCH_HOSTNAME) or something when the connection fails. Protocol.connectionFailed goes bye-bye.
Please do not clobber the information given by the kernel in errno. Translating errno to 2 different failures is not nice.
It needs to be clobbered, at least in some sense, for portability. Jython does not have errno and win32's support for it is very weak. -- | <`'> | Glyph Lefkowitz: Traveling Sorcerer | | < _/ > | Lead Developer, the Twisted project | | < ___/ > | http://www.twistedmatrix.com |
