Seriously, this is awesome. Would you join the team and continue your work on the SCTP transport? Merging this pull request without letting you contribute directly doesn't make much sense in my opinion. :-) |

Nice work... Anyway I would prefer to move all the "implementations" out of the core library. What about splitting netty into multiple jars. Something like: netty-core This will allow us to keep the core slim in the future ;) WDYT ? |

@trustin I really like to join the team :) . Thanks a lot |

@normanmaurer, I agree :) . Since sctp is not supported in windows for JDK 1.7 , The only way, we have: splitting netty into multiple modules. I know, there are people using netty only for its rich buffer support , they will not be affected . |
…hannel buffer size setter/getters 3)updated sctp examples

Welcome to the team, and please feel free to work in the upstream as long as you don't break anything. :-) |

thanks :) . I will start merging with upstream soon. |
…onstructor 3)added maven exec plugin
…ecution handler implementers can have a down stream execution handler for SEDA
…e to avoid high cpu usage 2)optimized selector loop

There was a problem hiding this comment.
Fire events from within the constructor should not get done as it may pass an an not 100 % initialized object to it.

Thanks for pointing it, I will do the changes :-)

Is the com.sun.nio.* package only in java 7 ? As I have compile errors with java 6 |
Member

Yes its only available in Java 7, shall we move this to a branch? |
Member

Yes I think this will make sense. We should move it back once we have multi-module support as we could just require java7 for it then. |

Motivation:
ReferenceCountedOpenSslEngine is careful to lock access to `ssl`
almost everywhere (manually verified) *except* in the constructor.
Since `ssl` is non-final, it does not enjoy automatic thread safety
of the code that uses it. Specifically, that means netty tcnative
code is not thread safe.
Modifications:
Ensure that all ssl engine intialization and variables related to
it are properly synchronized by adding in the constructor.
Result:
Less noisy race detector.
Notes:
The specific racing threads are:

Motivation:
ReferenceCountedOpenSslEngine is careful to lock access to `ssl`
almost everywhere (manually verified) *except* in the constructor.
Since `ssl` is non-final, it does not enjoy automatic thread safety
of the code that uses it. Specifically, that means netty tcnative
code is not thread safe.
Modifications:
Ensure that all ssl engine intialization and variables related to
it are properly synchronized by adding in the constructor.
Result:
Less noisy race detector.
Notes:
The specific racing threads are:

Motivation:
ReferenceCountedOpenSslEngine is careful to lock access to `ssl`
almost everywhere (manually verified) *except* in the constructor.
Since `ssl` is non-final, it does not enjoy automatic thread safety
of the code that uses it. Specifically, that means netty tcnative
code is not thread safe.
Modifications:
Ensure that all ssl engine intialization and variables related to
it are properly synchronized by adding in the constructor.
Result:
Less noisy race detector.
Notes:
The specific racing threads are:

Motivation: While it is highly recommended to use tokens during QUIC connection establishment it is not really required by the spec and there may be use-cases where token validation is not needed and so the extra roundtrip can be eliminated Modifications: - Change QuicTokenHandler.writeToken(...) method to return either true or false. If true is returned a token is used and validation is used. If false is returned it will just accept the connection - Adjust QuicheQuicServerCodec to account for this - Add unit test that verifies we can use no tokens Result: Fixes netty/netty-incubator-codec-quic#1 .

Hi Trustin,
Followings are available with this pull request,
I have tested with my linux box with lksctp 1.0.11, it worked fine :)
(Most of the classes are copied and modified form nio socket , not nio datagram. Since sctp uses socket, it was easy to modify nio socket classes)
The current code has faire amount of duplicates, looking forward for your suggestion to improve it.
