calling encode(). Without the fix, it ended up in calling the exception "java.lang.StringIndexOutOfBoundsException". * Also added test case to verify the patch Change-Id: Ib96425e07ab50be027ade7be0748cceb6438a586
…de to close channel twice
Applied the patch provided by Greg Dhuse.
…egion cannot be cast to org.jboss.netty.buffer.ChannelBuffer * Updated JavaDoc to let users know that not all transports support FileRegion * Added FIXME for future improvement
* Added support for Message.Builder
Applied the patch provided by Greg Dhuse.
something Modified the pipeline implementations so that it rejects the attempt to send an UpstreamMessageEvent to downstream
…ctly * Fixed a bug where signed comparison is made where unsigned comparison is expected
…t the same time * Fixed incorrect isPartialSuccess(), isPartialFailure(), isCompleteFailure() implementation
… handling Channel.close() * Made sure the ChannelFuture associated with a downstream event is marked as failure when an exception is raised before it reaches at ChannelSink.
… notified when the channel was closed already when SslHandler attempts to send a closure_notify. This shouldn't be a problem to most applications because they usually do not specify their own future object for the close request.
* Fixed a race condition where NioSocketChannel's state variable is updated *after* its close future is notified * Removed unnecessary use of ChannelFutureListeners in NioSocketChannel and AbstractChannel
* Fixed a bug in SslHandler where a write attempt made after SSLEngine is closed result in unnotified future. Fixed by respecting the case where SslEngineResult.Status == CLOSED
…ng the java.lang.Class instance of an interface type * Fixed a bug where deserializing an interface class fails due to wrong lookup. * Implemented class lookup caching
…Encoding: chunked responses * Reverted back the workaround for servers that sends unnecessary zero-byte chunk in a HEAD response because it actually breaks the codec when the server that conforms to the RFC.
…y the pipeline dynamically.
ChunkedWriteHandler.discard() do not issue write requests to trigger exceptionCaught events and to notify write futures anymore. Instead, it triggers exceptionCaught events and notifies write futures by itself. Therefore, no write lock is involved during discard(), avoiding the reported dead lock. However, this is a temporary solution, and eventually Netty must introduce more robust event thread model.
…eams that does have sane implementation of available() method * Updated JavaDoc so that users don't specify an InputStream with poor available() implementation.
…me handshake failure cases. * Made sure SslHandler.handshake() and SslHandler.close() trigger an exceptionCaught event when failed
…ontinue' response to HttpContentDecoder. * Fixed a silly coding mistake where I sent the event in the opposite direction
…out.cancel() * Replaced a volatile boolean flag and system date access with an atomic integer flag.
…rameException * Fixed a bug where TooLongFrameException is not raised immediately when the large frame was fully decoded at the first attempt * Fixed a bug where LengthFieldBasedFrameDecoder does not reset its state completely after raising TooLongFrameException

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:

…g channel before (netty#17) Motivation: It's not required to connect the datagram before when using QUIC. Modifications: - Allow to use QUIC with non connected datagrams by allow to specify a remote address with building the QuicConnectionAddress - Rename QuicConnectionIdAddressGenerator to QuicConnectionIdGenerator as it only generates ids anymore - Change return types of QuicConnectionIdAddressGenerator to be ByteBuffer to be more flexible - Move static factory to QuicBuilder Result: Fixes netty/netty-incubator-codec-quic#15

Motivation: We should advertise the max header sizer via the Http3SettingsFrame so the remote peer knows what to expect. Modifications: Modify the Http3SettingsFrame if needed and advertise the max header size. Result: More conform to the spec
