…viour of high / low water marks on the interest ops of nio channels.
…. In order to get the tests to pass, I had to change the surefire fork policy from "never" to "once", as it seems the classloader settings used by the maven process were preventing jmock from mocking package private interfaces.

…http package, replacing the original implementation. Existing usage example has been deleted and should be replaced by an updated example using the new API.

Thanks, Iain. Let me take a look and merge soon. On Fri 08 Apr 2011 10:34:49 PM KST, iainmcgin wrote:

I've just picked up all commits but 3bb6a91 to upstream. Could you please confirm if it has been merged correctly? Once confirmed, I'll close this request. |

Quite possibly I've screwed up if it doesn't look right to you, due to lack of familiarity with git. I'm at a conference just now so I don't have a lot of time to look at this just now, but I'll check it over next week. |

I'm not sure. Did you find anything wrong with the merged result? On Tue 19 Apr 2011 07:56:46 AM KST, iainmcgin wrote:

I've checked through the source and all the necessary changes seem to be in place on netty/netty, so I think it's safe to close this. I'm going to have to learn more about git and github to be able to more confidently answer questions like this in future - 3bb6 was simple the merge of the netty/netty trunk into my fork with no other changes, so it surely shouldn't have appeared as something that needed remerged back into netty/netty? |

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.

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:

…etty#12) Motivation: 0a925f2 did fix a problem related to putting the decoder / encoder into the right position of the pipeline. That said we can make this even easier by just combine the decoder and encoder into one handler and use replace. Modifications: Introduce Http3FrameCodec and use it everywhere Result: Less error-prone code
