Yes, in HyBi 00 (Hixie 76) era, there was not close status feature, so there're many existing apps using close calls with no argument. But I think those close()s were not only for normal closure but also for any kind of closure which include application level errors which are now mapped to 3XXX status codes in RFC 6455. So, IMO, corresponding close() to 1005 (unknown) makes more sense. So, developers should do either of the followings in RFC 6455 era: - (want to utilize status) client uses close(1000) and server takes 1005 as an error - (not want to utilize status) client uses close() and server ignores contents in a close frame -- saves two octets of a close frame I think there's some demand for the latter ... (*) > 1005 should be interpreted at server level as some sort of warning (no error > code, no 1000 "I'm done" code... strange). I slightly prefer leaving what should be taken as strange cases up to users because of (*). 1005 clearly means the endpoint received the close frame successfully but there was no status code in it. Not ambiguous/confusing at all. As far as we make sure that UA sends a close frame without status code for close call without any argument, it's fully controllable by JavaScript code on the UA whether to put status code or not. > No one can manually send 1005 code, in WS.close method, so this defaults would > require to specify 1000 all the time, always... It would be better to default > to it from program code and leave 1005 to actual UI/server communication in > strange cases. As far as we keep a way to send a close frame without status code (that might be close() or close(null)), I think we should make the API be asking developers to explicitly specify status code not to have close() calls unconsciously saying "it's successful!" rather than saving typing. If we define close(null) (or something else) to send a close frame without status code instead of close(), it's a bit more confusing than current one. ---- If it turned out that (*) is false, Your suggestion might make more sense. -- Configure bugmail: https://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
