If EOF is encountered w/out a blank line it should be considered an incomplete/corrupted event. The "fix" for the spec would be to drop the line Once the end of the file is reached, the user agent must dispatch the event one final time, as defined below. For clarity something explicit could be added If the end of the file is reached while collecting data and before encountering a blank line the incomplete event must not be dispatched. ]] 50720 2 art.barstow 2011-07-06 11:22:57 +0000 See Anne van Kesteren's reply to Dan Veditz (comment #1): http://lists.w3.org/Archives/Public/public-webapps/2011JulSep/0127.html [[ The ABNF in http://dev.w3.org/html5/eventsource/#parsing-an-event-stream would also need updating. ]] 54199 3 contributor 2011-08-04 21:54:14 +0000 Checked in as WHATWG revision r6371. Check-in comment: Change text/event-stream to drop final events not followed by a blank line, since otherwise interrupted streams would fire incomplete events. http://html5.org/tools/web-apps-tracker?from=6370&to=6371
