1f6782894a OpenSslEngine wrap with heap buffer bug
Motivation:
ReferenceCountedOpenSslEngine#wrap must have a direct buffer for a destination to interact with JNI. If the user doesn't supply a direct buffer we internally allocate one to write the results of wrap into. After this operation completes we copy the contents of the direct buffer into the heap buffer and use internalNioBuffer to get the content. However we pass in the end index but the internalNioBuffer expects a length.

Modifications:
- pass the length instead of end index to internalNioBuffer

Result:
ReferenceCountedOpenSslEngine#wrap will copy the correct amount of data into the destination buffer when heap buffers are wrapped.

Modifications:
- Make the hpack classes package private in the http2 package

Result:
Less APIs exposed as public.

79e24d1a17 Add javadoc warning on SslContext#newHandler client-side
Motivation:

SslContext#newHandler currently creates underlying SSLEngine without
enabling HTTPS endpointIdentificationAlgorithm. This behavior in
unsecured when used on the client side.

We can’t harden the behavior for now, as it would break existing
behavior, for example tests using self signed certificates.

Proper hardening will happen in a future major version when we can
break behavior.

Modifications:

Add javadoc warnings with code snippets.

Result:

Existing unsafe behavior and workaround documented.

ca2c349a4a Correctly have exceptions thrown from decode(...) method be wrapped with DecodingException
Motivation:

Normally if a decoder produces an exception its wrapped with DecodingException. This is not the cause for NotSslRecordException in SslHandler and SniHandler.

Modifications:

Just throw the NotSslRecordException exception for decode(...) and so ensure its correctly wrapped in a DecodingException before its passed through the pipeline.

Result:

Consist behavior.

4734ef61a5 Mark transport udt as deprecated as barchart-udt is not maintained anymore
Motivation:

barchart-udt is not maintained anymore so there is not way for us to get fixes for udt. Because of this we should mark the transport as deprecated.

Modifications:

Deprecate all udt classes.

Result:

transport udt is deprecated and so the user knows it will be removed in the future.

70bcb40855 OpenSslEngine may use networkBIO after calling shutdown
Motivation:
To ensure that all bytes queued in OpenSSL/tcnative internal buffers we invoke SSL_shutdown again to stimulate OpenSSL to write any pending bytes. If this call fails we may call SSL_free and the associated shutdown method to free resources. At this time we may attempt to use the networkBIO which has already been freed and get a NPE.

Modifications:
- Don't call bioLengthByteBuffer(networkBIO) if we have called shutdown() in ReferenceCountedOpenSslEngine

Result:
Fixes https://github.com/netty/netty/issues/6466

c0cd3db5b1 Fix class references of its subclass issue
Motivation:

Realization of `AbstractTrafficShapingHandler.userDefinedWritabilityIndex()` has references to subclasses.
In addition, one of the subclasses overriding it, but the other does not.

Modifications:

Add overriding to the second subclass. Remove references to subclasses from parent class.

Result:

More consistent and clean code (OOP-stylish).

22ccf6c7b1 Fix test-failures introduced 325cc84a2e on Java7
Motivation:

325cc84a2e introduced new tests which uses classes only provided by Java8+. We need to ensure we only try to load classes needed for these when we run the tests on Java8+ so we still can run the testsuite with Java7.

Modifications:

Add extra class which only gets loaded when Java8+ is used and move code there.

Result:

No more class-loader issue when running tests with Java7.

deb90923a2 Ensure PooledByteBuf.initUnpooled(...) correctly set the allocator
Motivation:

Commit 8dda984afe introduced a regression which lead to the situation that the allocator is not set when PooledByteBuf.initUnpooled(...) is called. Thus it was possible that PooledByteBuf.alloc() returns null or the wrong allocator if multiple PooledByteBufAllocator are used in an application.

Modifications:

- Correctly set the allocator
- Add test-case

Result:

Fixes [#6436].

7d08b4fc35 Remove optional dependency on javassist
Motivation:

We shipped a javassist based implementation for typematching and logged a confusing debug message about missing javassist. We never were able to prove it really gives any perf improvements so we should just remove it.

Modifications:

- Remove javassist dependency and impl
- Fix possible classloader deadlock as reported by intellij

Result:

Less code to maintain and less confusing log message.

77e65fe6bb Base64 reduce byte manipulation operations
Motivation:
Base64#decode4to3 generally calculates an int value where the contents of the decodabet straddle bytes, and then uses a byte shifting or a full byte swapping operation to get the resulting contents. We can directly calculate the contents and avoid any intermediate int values and full byte swap operations. This will reduce the number of operations required during the decode operation.

Modifications:
- remove the intermediate int in the Base64#decond4to3 method.
- manually do the byte shifting since we are already doing bit/byte manipulations here anyways.

Result:
Base64#decode4to3 requires less operations to compute the end result.

7feb92959e Improve performance of Base64.decode and encode methods.
Motivation:

The decode and encode method uses getByte(...) and setByte(...) in loops which can be very expensive because of bounds / reference-count checking. Beside this it also slows-down a lot when paranoid leak-detection is enabled as it will track each access.

Modifications:

- Pack bytes into int / short and so reduce operations on the ByteBuf
- Use ByteProcessor to reduce getByte calls.

Result:

Better performance in general. Also when you run the build with -Pleak the handler module will build in 1/4 of the time it took before.

b1436e80ef Cleanup DefaultHttp2FrameReader about verifyUnknownFrame
Motivation:

In previous PR about handling unknwon frame in the middle of header
block, I didn't notice and re-use about checking is processing header
. And I added a redundant method for same functionality.
I think that the redundant method would lead to some misleading
situation.

Modifications:

Removed redundant code on DefaultHttp2FrameReader

Result:

08e0c612cf HTTP/2 Unit Test LocalChannel Leaks
Motivation:
Some unit HTTP/2 unit tests use LocalChannel. LocalChannel's doClose method will ensure any pending items in the queue will be released, but it may execute a Runnable on the peer's EventLoop to ensure the peer's queue is also cleaned up. The HTTP/2 unit tests close the event loop groups with no wait time so that unit tests will execute quickly, but if the doClose Runnable is in the EventLoop's queue it will not run and thus the items in the queue will not be released.

Modifications:
- Ensure all HTTP/2 unit tests which use LocalChannel wait for both client and server channels to be closed before closing the EventLoop.

Result:
Related to https://github.com/netty/netty/issues/5850.

2dffc2f9fb SSLEngineTest issue introduced by d8e6fbb9c3
Motivation:
d8e6fbb9c3 attempted to account for the JDK not throwing the expected SSLHandshakeException by allowing a SSLException to also pass the test. However in some situations the SSLException will not be the top level exception and the Throwable must be unwrapped to see if the root cause is an SSLException.

Modifications:
- Unwrap exceptions thrown by the JDK's SSLEngine to check for SSLException.

Result:
SSLEngineTest (and derived classes) are more reliable.

d0a3877535 Ensure trying to recover from exceptionCaught on the ServerChannel works as expected
Motivation:

When "Too many open files" happens,the URLClassLoader cannot do any classloading because URLClassLoader need a FD  for findClass. Because of this the anonymous inner class that is created to re-enable auto read may cause a problem.

Modification:

Pre-create Runnable that is scheduled and so ensure it is not lazy loaded.

Result:

No more problems when try to recover.
