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:
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.
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:
maven-antrun-plugin does not redirect stdin, and thus it's impossible to
run interactive examples such as securechat-client and telnet-client.
org.codehaus.mojo:exec-maven-plugin redirects stdin, but it buffers
stdout and stderr, and thus an application output is not flushed timely.
Modifications:
Deploy a forked version of exec-maven-plugin which flushes output
buffers in a timely manner.
Result:
Interactive examples work. Launches faster than maven-antrun-plugin.
Motivation:
The examples have not been updated since long time ago, showing various
issues fixed in this commit.
Modifications:
- Overall simplification to reduce LoC
- Use system properties to get options instead of parsing args.
- Minimize option validation
- Just use System.out/err instead of Logger
- Do not pass config as parameters - just access it directly
- Move the main logic to main(String[]) instead of creating a new
instance meaninglessly
- Update netty-build-21 to make checkstyle not complain
- Remove 'throws Exception' clause if possible
- Line wrap at 120 (previously at 80)
- Add an option to enable SSL for most examples
- Use ChannelFuture.sync() instead of await()
- Use System.out for the actual result. Use System.err otherwise.
- Delete examples that are not very useful:
- applet
- websocket/html5
- websocketx/sslserver
- localecho/multithreaded
- Add run-example.sh which simplifies launching an example from command
line
- Rewrite FileServer example
Result:
Shorter and simpler examples. A user can focus more on what it actually
does than miscellaneous stuff. A user can launch an example very
easily.
Motivation:
exec-maven-plugin does not flush stdout and stderr, making the console
output from the examples invisible to users
Modification:
Use maven-antrun-plugin instead
Result:
A user sees the output from the examples immediately.
Motivation:
- OpenSslEngine and JDK SSLEngine (+ Jetty NPN) have different APIs to
support NextProtoNego extension.
- It is impossible to configure NPN with SslContext when the provider
type is JDK.
Modification:
- Implement NextProtoNego extension by overriding the behavior of
SSLSession.getProtocol() for both OpenSSLEngine and JDK SSLEngine.
- SSLEngine.getProtocol() returns a string delimited by a colon (':')
where the first component is the transport protosol (e.g. TLSv1.2)
and the second component is the name of the application protocol
- Remove the direct reference of Jetty NPN classes from the examples
- Add SslContext.newApplicationProtocolSelector
Result:
- A user can now use both JDK SSLEngine and OpenSslEngine for NPN-based
protocols such as HTTP2 and SPDY
Motivation:
Build fails with JDK 8 because npn-boot does not work with JDK 8
Modifications:
Do not specify bootclasspath when on JDK 8
Result:
Build is green again.
Motivation:
Due to a known problem[1] of maven-compiler-plugin, our build always
compiles everything from scratch, which is waste of time.
Modifications:
Exclude package-info.java from the source list.
Result:
Much shorter build time.
[1]: https://jira.codehaus.org/browse/MCOMPILER-205
Motivation:
- example/pom.xml has quite a bit of duplication.
- We expect that we depend on npn-boot in more than one module in the
near future. (e.g. handler, codec-http, and codec-http2)
Modification:
- Deduplicate the profiles in example/pom.xml
- Move the build configuration related with npn-boot to the parent pom.
- Add run-example.sh that helps a user launch an example easily
Result:
- Cleaner build files
- Easier to add a new example
- Easier to launch an example
- Easier to run the tests that relies on npn-boot in the future
Motivation:
Some users already use an SSLEngine implementation in finagle-native. It
wraps OpenSSL to get higher SSL performance. However, to take advantage
of it, finagle-native must be compiled manually, and it means we cannot
pull it in as a dependency and thus we cannot test our SslHandler
against the OpenSSL-based SSLEngine. For an instance, we had #2216.
Because the construction procedures of JDK SSLEngine and OpenSslEngine
are very different from each other, we also need to provide a universal
way to enable SSL in a Netty application.
Modifications:
- Pull netty-tcnative in as an optional dependency.
http://netty.io/wiki/forked-tomcat-native.html
- Backport NativeLibraryLoader from 4.0
- Move OpenSSL-based SSLEngine implementation into our code base.
- Copied from finagle-native; originally written by @jpinner et al.
- Overall cleanup by @trustin.
- Run all SslHandler tests with both default SSLEngine and OpenSslEngine
- Add a unified API for creating an SSL context
- SslContext allows you to create a new SSLEngine or a new SslHandler
with your PKCS#8 key and X.509 certificate chain.
- Add JdkSslContext and its subclasses
- Add OpenSslServerContext
- Add ApplicationProtocolSelector to ensure the future support for NPN
(NextProtoNego) and ALPN (Application Layer Protocol Negotiation) on
the client-side.
- Add SimpleTrustManagerFactory to help a user write a
TrustManagerFactory easily, which should be useful for those who need
to write an alternative verification mechanism. For example, we can
use it to implement an unsafe TrustManagerFactory that accepts
self-signed certificates for testing purposes.
- Add InsecureTrustManagerFactory and FingerprintTrustManager for quick
and dirty testing
- Add SelfSignedCertificate class which generates a self-signed X.509
certificate very easily.
- Update all our examples to use SslContext.newClient/ServerContext()
- SslHandler now logs the chosen cipher suite when handshake is
finished.
Result:
- Cleaner unified API for configuring an SSL client and an SSL server
regardless of its internal implementation.
- When native libraries are available, OpenSSL-based SSLEngine
implementation is selected automatically to take advantage of its
performance benefit.
- Examples take advantage of this modification and thus are cleaner.
