Motivation:
Avoid multiple search in fragments map
Modifications:
Replace usage of Map.containsKey by Map.remove
Result:
During packet process, fragment is only search once in the map instead of 3 times in the previous worst case
Motivation:
The SCTP_INIT_MAXSTREAMS property is ignored on NioSctpServerChannel / OioSctpServerChannel.
Modifications:
- Correctly use the netty ChannelOption
- Ensure getOption(...) works
- Add testcase.
Result:
SCTP_INIT_MAXSTREAMS works.
Motivation:
JCTools supports both non-unsafe, unsafe versions of queues and JDK6 which allows us to shade the library in netty-common allowing it to stay "zero dependency".
Modifications:
- Remove copy paste JCTools code and shade the library (dependencies that are shaded should be removed from the <dependencies> section of the generated POM).
- Remove usage of OneTimeTask and remove it all together.
Result:
Less code to maintain and easier to update JCTools and less GC pressure as the queue implementation nt creates so much garbage
Motivation:
See https://github.com/netty/netty-build/issues/5
Modifications:
Add xml-maven-plugin to check indentation and fix violations
Result:
pom.xml will be checked in the PR build
Motivation:
Not all fields of SctpMessage which used to check message equality are used
to generate hashcode.
Modifications:
Use value of 'unordered' field in hashCode method.
Result:
Better hash function of SctpMessage.
Motivation:
SctpMessage.duplicate() copied message content that leads to additional buffer
allocation and memory copying.
Modifications:
Duplicate message content instead of copying it.
Result:
Better performace and less memory consumption.
Motivation:
The fix for https://github.com/netty/netty/issues/3884 breaks SctpEchoTest because Selector.select will always return 0 if you do not clear last selectedKeys.
Modifications:
Clear readSelector.selectedKeys() if it is not empty.
Result:
SctpEchoTest is green again.
Motivation:
We should use OneTimeTask where possible to reduce object creation.
Modifications:
Replace Runnable with OneTimeTask
Result:
Less object creation
Motivation:
As toString() is often used while logging we need to ensure this produces no exception.
Modifications:
Ensure we never throw an IllegalReferenceCountException.
Result:
Be able to log without produce exceptions.
Motivation:
OioSctpChannel.doReadMessages is iterating over the selected keys, and ignoring each selected key. It is not known why this is needed and no other channel implementation does this.
Modifications:
- Stop iterating over selected keys, and just read like other channels
Result:
No unnecessary iteration in OioSctpChannel.doReadMessages.
Fixes https://github.com/netty/netty/issues/3884
Motivation:
Some SCTP applications require the SCTP unordered flag.
This flag was not exposed by Netty so applications were unable
to use it.
Modifications:
- Add unordered flag to SctpMessage.
- {Nio,Oio}SctpChannel pass unordered flag to MessageInfo on write.
- SctpOutboundByteStreamHandler may optionally request unordered
delivery for all outbound messages.
- Added test case to SctpEchoTest using unordered flag.
Result:
Fixes#3698. New constructors and methods added to SctpMessage and
SctpOutboundByteStreamHandler, but changes are backward compatible.
