QE observes that, if the remote TCP server process is killed, the -didCompleteWithError: delegate method is not called; instead readClosedForStreamTask: is called. Since I’ve been unsure what the latter method is for, my implementation just logs a message and does nothing. The end result is that the app thinks the connection is still open even though it isn’t. The docs for the method (below) seem to imply the socket is in a “half-open” state, which seems incorrect in this case because the remote socket was closed completely by the kernel on process exit. In any case, what should I do in response to -readClosedForStreamTask:? Should I call -readDataOfMinLength:…? Should I then wait for -didCompleteWithError: to be called, or does it not get called at all in this situation? /* Indiciates that the read side of a connection has been closed. Any * outstanding reads complete, but future reads will immediately fail. * This may be sent even when no reads are in progress. However, when * this delegate message is received, there may still be bytes * available. You only know that no more bytes are available when you * are able to read until EOF. */ - (void)URLSession:(NSURLSession *)session readClosedForStreamTask:(NSURLSessionStreamTask *)streamTask; —Jens _______________________________________________ Do not post admin requests to the list.
