Content-Type: text/plain Message-Id: <20181112022847.A3C01E10E1@git1-us-west.apache.org> Date: Mon, 12 Nov 2018 02:28:47 +0000 (UTC) GitHub user ivmaykov reopened a pull request: https://github.com/apache/zookeeper/pull/679 ZOOKEEPER-3172: Quorum TLS - fix port unification to allow rolling upgrades Fix numerous problems with UnifiedServerSocket, such as hanging the accept() thread when the client doesn't send any data or crashing if less than 5 bytes are read from the socket in the initial read. Re-enable the "portUnification" config option. ## 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 read - 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.
