Subject [GitHub] zookeeper issue #184: ZOOKEEPER-236: SSL Support for Atomic Broadcast protoc...

Github user enixon commented on the issue:

    For context on the second pull request, testing at Facebook revealed a bug in the existent
form of 184. From #627 notes:
    > Fixed networking issues/bugs in UnifiedServerSocket
    > -   don't crash the accept() thread if the client closes the connection without sending
any data
    > -   don't corrupt the connection if the client sends fewer than 5 bytes for the initial
    > -   delay the detection of TLS vs. plaintext mode until a socket stream is read from
or written to. This prevents the accept() thread from getting blocked on a read() operation
from the newly connected socket.
    > -   prepending 5 bytes to PrependableSocket and then trying to read >5 bytes would
only return the first 5 bytes, even if more bytes were available. This is fixed.
    The fix for this issue is entangled in other code that was written as an extension of
184. As github does not seem to support stacked pull requests, we're offering 627 as a mix
"184 + extensions + bug fix" as a way of at least sharing what we know. If there are low cost
ways of presenting that work more cleanly, please share.
