Modifications:
- Add jetty.npn.version.latest and jetty.alpn.version.latest7/8
- Add npn-alpn-7 profile
- Use the *.latest7/8 version properties in alpn-8 and npn-alpn-7
- Add more profiles for newer JDK versions
- Reorder profiles
Motivation:
Right now the used hpack dependency does not contain a valid osgi manifest.
Modifications:
Upgrade hpack from 0.10.1 to 0.11.0.
Result:
hpack dependency works in osgi containers without wrapping.
Motivation:
Many projects need some kind a Channel/Connection pool implementation. While the protocols are different many things can be shared, so we should provide a generic API and implementation.
Modifications:
Add ChannelPool / ChannelPoolMap API and implementations.
Result:
Reusable / Generic pool implementation that users can use.
Motivation:
To support HTTP2 we need APLN support. This was not provided before when using OpenSslEngine, so SSLEngine (JDK one) was the only bet.
Beside this CipherSuiteFilter was not supported
Modifications:
- Upgrade netty-tcnative and make use of new features to support ALPN and NPN in server and client mode.
- Guard against segfaults after the ssl pointer is freed
- support correctly different failure behaviours
- add support for CipherSuiteFilter
Result:
Be able to use OpenSslEngine for ALPN / NPN for server and client.
Motivation:
Too many duplicated code of tests for different compression codecs.
Modifications:
- Added abstract classes AbstractCompressionTest, AbstractDecoderTest and AbstractEncoderTest which contains common variables and tests for any compression codec.
- Removed common tests which are implemented in AbstractDecoderTest and AbstractEncoderTest from current tests for compression codecs.
- Implemented abstract methods of AbstractDecoderTest and AbstractEncoderTest in current tests for compression codecs.
- Added additional checks for current tests.
- Renamed abstract class IntegrationTest to AbstractIntegrationTest.
- Used Theories to run tests with head and direct buffers.
- Removed code duplicates.
Result:
Removed duplicated code of tests for compression codecs and simplified an addition of tests for new compression codecs.
Motivation:
For some use cases X509ExtendedTrustManager is needed as it allows to also access the SslEngine during validation.
Modifications:
Add support for X509ExtendedTrustManager on java >= 7
Result:
It's now possible to use X509ExtendedTrustManager with OpenSslEngine
Motivations:
JDK 1.8 adds default methods to collections classes that reference
classes that don't exist in JDK 7. That's binary compatible,
but not source compatible.
Modifications:
Enforce JDK version to be 1.7.* when releasing
Result:
Fixes#3548
Motivation:
There are new versions of the ALPN and NPN dependencies. There was also some backport misses in the pom file related to ALPN/NPN.
Modifications:
- Add new versions for ALPN/NPN dependencies.
- Backport missed pieces from pom.xml.
Result:
Updated version of ALPN/NPN versions.
Motivation:
Twitter hpack has upgraded to 0.10.1 to fix a parsing bug.
Modifications:
Updated the parent pom to specify the dependency version.
Result:
HTTP/2 updated to the latest hpack release.
Motivation:
Provide non-blocking XML parser as Netty codec.
Modifications:
New codec implemented/extracted.
io.netty.handler.codec.xml.XmlDecoder decodes XML fed by Netty without blocking.
Result:
Non-blocking XML stream parsing.
Motivation:
Release 4.0.25 was not usable in OSGi environments due to a simple typo.
An automated test could have caught the problem even before it was
committed.
Modifications:
This patch introduces a new artifact, osgitests, which pulls in all
production artifacts (which we want to be checked for OSGi compliance).
It contains only a single unit test, which runs a pax-exam container
with felix OSGi.
At initialization time, it scans all the artifact's dependencies,
looking for things belonging to io.netty group. The container is
configured to deploy those artifacts as bundles and fail if any bundle
is found to be unresolved. It performs a final check to see if any
bundles were tested this way, to make sure the mechanism is not
completely broken.
We are using wrappedBundle(), as two of our third-party dependencies do
not export packages correctly -- this masks the problem, assuming that
whoever deploys our artifacts depending on them will figure out how to
OSGify them.
Result:
Simple typos and other bundle manifest errors should be caught during
test phase of every build.
Motivation:
HTTP/2 codec was implemented in master branch.
Since, master is not yet stable and will be some time before it gets released, backporting it to 4.1, enables people to use the codec with a stable netty version.
Modification:
The code has been copied from master branch as is, with minor modifications to suit the `ChannelHandler` API in 4.x.
Apart from that change, there are two backward incompatible API changes included, namely,
- Added an abstract method:
`public abstract Map.Entry<CharSequence, CharSequence> forEachEntry(EntryVisitor<CharSequence> visitor)
throws Exception;`
to `HttpHeaders` and implemented the same in `DefaultHttpHeaders` as a delegate to the internal `TextHeader` instance.
- Added a method:
`FullHttpMessage copy(ByteBuf newContent);`
in `FullHttpMessage` with the implementations copied from relevant places in the master branch.
- Added missing abstract method related to setting/adding short values to `HttpHeaders`
Result:
HTTP/2 codec can be used with netty 4.1
Motivation:
The latest stable RHEL version of 6.x is now 6.6.
Modification:
Update pom.xml's validation configuration
Result:
Can release on the latest stable RHEL version in 6.x
Motivation:
We only support openssl for server side at the moment but it would be also useful for client side.
Modification:
* Upgrade to new netty-tcnative snapshot to support client side openssl support
* Add OpenSslClientContext which can be used to create SslEngine for client side usage
* Factor out common logic between OpenSslClientContext and OpenSslServerContent into new abstract base class called OpenSslContext
* Correctly detect handshake failures as soon as possible
* Guard against segfault caused by multiple calls to destroyPools(). This can happen if OpenSslContext throws an exception in the constructor and the finalize() method is called later during GC
Result:
openssl can be used for client and servers now.
Motivation:
ALPN version updates revealed an inconsistency visible by defaulting to npn when alpn was expected.
Modifications:
Default to ALPN.
Result:
Build and unit tests should pass.
Motivation:
There was a bug in the Java ALPN library we are using. A new version was released to fix this bug and we should update our pom.xml to use the new version.
Modifications:
Update pom.xml to use new ALPN library.
Result:
Newer versions of JDK (1.7_u71, 1.7_u72, 1.8_u25) have the bug fixed.
Motivation:
It takes too long to download the heap dump from the CI server.
Modifications:
Compress the heap dump as much as possible.
Result:
When heap dump is generated by certain test failure, the generated heap
dump file is about 3 times smaller than before, although the compression
time will increase the build time when the test fails.
Motivation:
We use 3 (!) libraries to build mock objects - easymock, mockito, jmock.
Mockito and jMock pulls in the different versions of Hamcrest, and it
conflicts with the version pulled by jUnit.
Modifications:
- Replace mockito-all with mockito-core to avoid pulling in outdated
jUnit and Hamcrest
- Exclude junit-dep when pulling in jmock-junit4, because it pulls an
outdated Hamcrest version
- Pull in the hamcrest-library version used by jUnit explicitly
Result:
No more dependency hell that results in NoSuchMethodError during the
tests
Motivation:
Improvements were made on the main line to support ALPN and mutual
authentication for TLS. These should be backported.
Modifications:
- Backport commits from the master branch
- f8af84d599
- e74c8edba3
Result:
Support for ALPN and mutual authentication.
Motivation:
So far, we relied on the domain name resolution mechanism provided by
JDK. It served its purpose very well, but had the following
shortcomings:
- Domain name resolution is performed in a blocking manner.
This becomes a problem when a user has to connect to thousands of
different hosts. e.g. web crawlers
- It is impossible to employ an alternative cache/retry policy.
e.g. lower/upper bound in TTL, round-robin
- It is impossible to employ an alternative name resolution mechanism.
e.g. Zookeeper-based name resolver
Modification:
- Add the resolver API in the new module: netty-resolver
- Implement the DNS-based resolver: netty-resolver-dns
.. which uses netty-codec-dns
- Make ChannelFactory reusable because it's now used by
io.netty.bootstrap, io.netty.resolver.dns, and potentially by other
modules in the future
- Move ChannelFactory from io.netty.bootstrap to io.netty.channel
- Deprecate the old ChannelFactory
- Add ReflectiveChannelFactory
Result:
It is trivial to resolve a large number of domain names asynchronously.
Related issue: #1133
Motivation:
There is no support for client socket connections via a proxy server in
Netty.
Modifications:
- Add a new module 'handler-proxy'
- Add ProxyHandler and its subclasses to support SOCKS 4a/5 and HTTP(S)
proxy connections
- Add a full parameterized test for most scenarios
- Clean up pom.xml
Result:
A user can make an outgoing connection via proxy servers with only
trivial effort.
Motivation:
LZMA compression algorithm has a very good compression ratio.
Modifications:
- Added `lzma-java` library which implements LZMA algorithm.
- Implemented LzmaFrameEncoder which extends MessageToByteEncoder and provides compression of outgoing messages.
- Added tests to verify the LzmaFrameEncoder and how it can compress data for the next uncompression using the original library.
Result:
LZMA encoder which can compress data using LZMA algorithm.
Motivation:
LZ4 compression codec provides sending and receiving data encoded by very fast LZ4 algorithm.
Modifications:
- Added `lz4` library which implements LZ4 algorithm.
- Implemented Lz4FramedEncoder which extends MessageToByteEncoder and provides compression of outgoing messages.
- Added tests to verify the Lz4FramedEncoder and how it can compress data for the next uncompression using the original library.
- Implemented Lz4FramedDecoder which extends ByteToMessageDecoder and provides uncompression of incoming messages.
- Added tests to verify the Lz4FramedDecoder and how it can uncompress data after compression using the original library.
- Added integration tests for Lz4FramedEncoder/Decoder.
Result:
Full LZ4 compression codec which can compress/uncompress data using LZ4 algorithm.
Related issue: #2508
Motivation:
The '<exec/>' task takes unnecessarily long time due to a known issue:
- https://issues.apache.org/bugzilla/show_bug.cgi?id=54128
Modifications:
- Reduce the number of '<exec/>' tasks for faster build
- Use '<propertyregex/>' to extract the output
Result:
Slightly faster build
Motivation:
LZF compression codec provides sending and receiving data encoded by very fast LZF algorithm.
Modifications:
- Added Compress-LZF library which implements LZF algorithm
- Implemented LzfEncoder which extends MessageToByteEncoder and provides compression of outgoing messages
- Added tests to verify the LzfEncoder and how it can compress data for the next uncompression using the original library
- Implemented LzfDecoder which extends ByteToMessageDecoder and provides uncompression of incoming messages
- Added tests to verify the LzfDecoder and how it can uncompress data after compression using the original library
- Added integration tests for LzfEncoder/Decoder
Result:
Full LZF compression codec which can compress/uncompress data using LZF algorithm.
MQTT is a open source protocol on top of TCP which is widely used in
mobile communication and also for IoT (Internet of Things) today. This
will add an open source implementation of MQTT so that it becomes easier
for Netty users to implement an MQTT application.

Motivation:
As part of GSOC 2013 we had @mbakkar working on a DNS codec but did not integrate it yet as it needs some cleanup. This commit is based on @mbakkar's work and provide the codec for DNS.
Modifications:
Add DNS codec
Result:
Reusable DNS codec will be included in netty.
This PR also includes a AsynchronousDnsResolver which allows to resolve DNS entries in a non blocking way by make use
of the dns codec and netty transport itself.
