Ian Clelland commented on CB-2293:
----------------------------------
Okay, I've done some analysis on this, and this is what I'm seeing --
. The first request succeeds normally; the client requests that the connection
remain open with "Connection: Keep-Alive" (explicit, but its the HTTP default
anyway).
. Five seconds later, if there are no other requests, the server closes its end
of the connection. That close isn't ACK'ed by the client, so it will still
attempt to send data.
. The next request is sent on the same connection, and the server immediately
sends RSTs to indicate that it will not accept it (as far as it is concerned,
the connection should be closed)
. Rather than reopen the connection to retry the request, Android's HTTP Client
rethrows the EOFException, and the second request simply fails. At this point,
the client accepts that the connection is closed.
. A third request will open a new connection and succeed like the first.
Android's behaviour in this case is buggy; it shouldn't be up to the
application code to explicitly retry the request.
(In fact, it looks like this was considered a bug
(https://code.google.com/p/android/issues/detail?id=41576) and just fixed
recently -- but that's not a solution for anyone with an existing device)
This particular issue is not (yet) fixed in OkHttp, but I'm going to look at
patching it there.
(We could also just wrap the FileTransfer request in a block that retries it
once on failure, but I'd rather not do that. There may be other reasons that a
request failed, and it may not be appropriate to retry a PUT/POST request if
the request may have been received and processed)
