Motivation:
This transport is unique because it uses Java's blocking IO (java.io / java.net) under the hood. However it is not clear if this transport is actually useful so it should be removed.
Modifications:
- Remove OIO transport and RXTX transport which depend on it.
- Remove Oio*Sctp* implementations
- Remove PerThreadEventLoop* which was only used by OIO transport.
Result:
Fixes https://github.com/netty/netty/issues/8510.
Motivation:
We plan to remove the OIO based transports in Netty 5 so we should mark these as deprecated already.
Modifications:
Mark all OIO based transports as deprecated.
Result:
Give the user a heads-up for removal.
Motivation
There is a cost to concatenating strings and calling methods that will be wasted if the Logger's level is not enabled.
Modifications
Check if Log level is enabled before producing log statement. These are just a few cases found by RegEx'ing in the code.
Result
Tiny bit more efficient code.
Motivation:
Some `if` statements contains common parts that can be extracted.
Modifications:
Extract common parts from `if` statements.
Result:
Less code and bytecode. The code is simpler and more clear.
Motivation:
SctpMessageCompletionHandler stores fragments in a Map but not release the stored ByteBuf when the handler is removed.
Modifications:
Release all buffers that are still in the Map when handlerRemoved(...) is called.
Result:
No more leaks for fragemented messages.
Automatic-Module-Name entry provides a stable JDK9 module name, when Netty is used in a modular JDK9 applications. More info: http://blog.joda.org/2017/05/java-se-9-jpms-automatic-modules.html
When Netty migrates to JDK9 in the future, the entry can be replaced by actual module-info descriptor.
Modification:
The POM-s are configured to put the correct module names to the manifest.
Result:
Fixes#7218.
Motivation:
The first parameter of SctpMessage is protocolIdentifier, and the second is streamIdentifier. So we need to swap the parameters in encode method
Modification:
Fix order
Result:
SctpOutboundByteStreamHandler works correctly.
