* Allow to use native transports when sun.misc.Unsafe is not present on the system
Motivation:
We should be able to use the native transports (epoll / kqueue) even when sun.misc.Unsafe is not present on the system. This is especially important as Java11 will be released soon and does not allow access to it by default.
Modifications:
- Correctly disable usage of sun.misc.Unsafe when -PnoUnsafe is used while running the build
- Correctly increment metric when UnpooledDirectByteBuf is allocated. This was uncovered once -PnoUnsafe usage was fixed.
- Implement fallbacks in all our native transport code for when sun.misc.Unsafe is not present.
Result:
Fixes https://github.com/netty/netty/issues/8229.
Motivation:
OpenSSL itself has an abstraction which allows you to customize some things. For example it is possible to load the PrivateKey from the engine. We should support this.
Modifications:
Add two new static methods to OpenSslX509KeyManagerFactory which allow to create an OpenSslX509KeyManagerFactory that loads its PrivateKey via the OpenSSL Engine directly.
Result:
More flexible usage of OpenSSL possible
Motivation:
There is a JDK bug which will return IP_TOS as supported option for ServerSocketChannel even if its not supported afterwards and cause an AssertionError.
See http://mail.openjdk.java.net/pipermail/nio-dev/2018-August/005365.html.
Modifications:
Add a workaround for the JDK bug.
Result:
ServerSocketChannel.config().getOptions() will not throw anymore and work as expected.
* Support the usage of SocketOption when nio is used and the java version >= 7.
Motivation:
The JDK uses SocketOption since java7 to support configuration options on the underyling Channel. We should allow to create a ChannelOption from a given SocketOption if nio is used. This also allows us to expose the same featureset in terms of configuration as the java nio implementation does without any extra effort.
Modifications:
- Add NioChannelOption which allows to wrap an existing SocketOption which then can be applied to the nio transport.
- Add test-cases
Result:
Support the same configuration options as the JDK. Also fixes https://github.com/netty/netty/issues/8072.
Motivation:
It's easy to break the support for shading native libs as shown in https://github.com/netty/netty/issues/8090. We should have some testing to ensure all works as expected.
Modification:
Add new testsuite which verifies that shading our native transports work as expected.
Result:
Include test to verify shading of native code.
Motivation:
A new version of tcnative was released that allows to use features depending on the runtime version of openssl, which makes it possible to use KeyManagerFactory and hostname verification on newer versions of centos/fedora/rhel and debian/ubuntu without the need to compile again.
Modifications:
Update to 2.0.12.Final
Result:
Use latest version of netty-tcnative to support more features.
Motiviation:
During profiling it showed that a lot of time during the handshake is spent by parsing the key / chain over and over again. We should cache these parsed structures if possible to reduce the overhead during handshake.
Modification:
- Use new APIs provided by https://github.com/netty/netty-tcnative/pull/360.
- Introduce OpensslStaticX509KeyManagerFactory which allows to wrap another KeyManagerFactory and caches the key material provided by it.
Result:
In benchmarks handshake times have improved by 30 %.
Motivation:
netty-tcnative 2.0.9 did not contain all native code for boringssl due a release mistake.
Modifications:
Update to 2.0.10
Result:
Use latest netty-tcnative release.
Motivation:
netty-tcnative 2.0.9.Final was released which fixes a memory leak that can happen if client auth is used via client side.
Modifications:
Update to latest netty-tcnative.
Result:
No more memory leak.
Motivation:
When using conscrypt some NPEs were logged, these were fixed in the latest release.
Modifications:
Update to conscrypt 1.1.3.
Result:
Fixes https://github.com/netty/netty/issues/7988.
Motivation:
The maven surefire plugin will trim stacktraces by default which makes these kind of use-less when trying to understand why an test failed because one was thrown.
Modifications:
Configure the plugin to not trim the stacktrace.
Result:
Easier to debug test-failures.
Netty/Transport/Native/Epoll project can be build on aarch64 platform as well.
Motivation:
To provide the support for AARCH64 architecture
Modification:
Adjusted regex for enforce plugin to also allow AARCH64.
Result:
Be able to compile on AARCH64
Motivation:
Java 11 will be out soon, so we should be able to build (and run tests) netty.
Modifications:
- Add dependency that is needed till Java 11
- Adjust tests so these also pass on Java 11 (SocketChannelImpl.close() behavious a bit differently now).
Result:
Build also works (and tests pass) on Java 11.
Motivation:
cff87de44c updated jboss-marshalling to 2.0.5.Final but this broke the ability to run tests with Java 7.
Modifications:
Only use 2.0.5.Final if compiled against Java 10 (as before 1.4.x works fine).
Result:
Be able to run tests with Java 7 on the CI.
Motivation:
Java 10 is out so we should be able to build netty with it (and run the tests).
Modifications:
- Update Mockito and JBoss Marshalling to support Java 10
- Fix unit test to not depend on specific cipher which is not present in Java 10 anymore
Result:
Netty builds (and runs all tests) when using Java 10
Motivation:
Currently, the testing-osgi is set to skip if run with java>=9. That is not necessary when using a newer version of Felix.
Modification:
Update to Felix framework 5.6.10 (which has better jpms support), add some more --add-opens to not have WARN messages, and remove the skipOsgiTestsuite setting from the parent pom.
Result:
OSGi tests run and pass on java>=9.
Motivation:
A new version of os-maven-plugin has been released.
Modifications:
- Update os-maven-plugin from 1.5.0 to 1.6.0
Result:
- No visible changes
- Feels good
Motivation:
We need to update jetty-alpn-agent to support java 1.8.0_162 while running our tests / examples.
Modifications:
Update jetty-alpn-agent to 2.0.7
Result:
All tests alpn related tests work again on latest java8 version
Motivation:
Conscrypt is now 1.0. No more need to depend on release candidates.
Modifications:
Just the version bump. Things seemed compatible.
Result:
Depending on first guaranteed-api-stable release of Conscrypt.
Motivation:
In environments with a security manager, the reflective access to get the reference to
Throwable#addSuppressed can cause issues that result in Netty failing to load. The main
motivation in this pull request is to remove the use of reflection to prevent issues in
these environments.
Modifications:
ThrowableUtil no longer uses Class#getDeclaredMembers to get the Method that references
Throwable#addSuppressed and instead guards the call to Throwable#addSuppressed with a
Java version check.
Additionally, a annotation was added that suppresses the animal sniffer java16 signature
check on the given method. The benefit of the annotation is that it limits the exclusion
of Throwable to just the ThrowableUtil class and has string text indicating the reason
for suppressing the java16 signature check.
Result:
Netty no longer requires the use of Class#getDeclaredMethod for ThrowableUtil and will
work in environments restricted by a security manager without needing to grant reflection
permissions.
Fixes#7614
Motivation:
Our tests are often asynchronous and have timeouts to avoid hanging indefinitely. However sometimes the timeouts maybe set to low for the CI servers. It would be helpful to confirm if the application was busy with GC and if that was a contributing factor to the test timing out.
Modifications:
- Unit tests should run with -XX:+PrintGCDetails by default
Result:
More visibility into GC behavior in unit tests.
Motivation:
H2Spec is a conformance testing tool for HTTP/2 implementation.
To help us fix failing tests and avoid future regression we
should run h2spec as part of the build
Modifications:
- Add testsuite-http2 module to the project
Result:
- Run h2spec as part of the build
- 22 tests are currently ignored, we should remove the ignore as we fix them
