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
Automatic-Module-Name entry provides a stable JDK9 module name, when Netty is used in a modular JDK9 applications. More info: http://blog.joda.org/2017/05/java-se-9-jpms-automatic-modules.html
When Netty migrates to JDK9 in the future, the entry can be replaced by actual module-info descriptor.
Modification:
The POM-s are configured to put the correct module names to the manifest.
Result:
Fixes#7218.
infinite loop
Motivation:
If SslHandler sets jdkCompatibilityMode to false and ReferenceCountedOpenSslEngine sets jdkCompatibilityMode to true there is a chance we will get stuck in an infinite loop if the peer sends a TLS packet with length greater than 2^14 (the maximum length allowed in the TLS 1.2 RFC [1]). However there are legacy implementations which actually send larger TLS payloads than 2^14 (e.g. OpenJDK's SSLSessionImpl [2]) and in this case ReferenceCountedOpenSslEngine will return BUFFER_OVERFLOW in an attempt to notify that a larger buffer is to be used, but if the buffer is already at max size this process will repeat indefinitely.
[1] https://tools.ietf.org/html/rfc5246#section-6.2.1
[2] http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/d5a00b1e8f78/src/share/classes/sun/security/ssl/SSLSessionImpl.java#l793
Modifications:
- Support TLS payload sizes greater than 2^14 in ReferenceCountedOpenSslEngine
- ReferenceCountedOpenSslEngine should throw an exception if a
BUFFER_OVERFLOW is impossible to rectify
Result:
No more infinite loop in ReferenceCountedOpenSslEngine due to
BUFFER_OVERFLOW and large TLS payload lengths.
Motivation:
We need to upgrade our dependencies to versions which use ASM 6.0.0+ to support compiling on java9.
Modifications:
Update animal-sniffer-maven-plugin and maven-shade-plugin.
Result:
Fixes https://github.com/netty/netty/issues/6100
Motivation:
Getting the latest Conscrypt goodies.
Modifications:
A few API changes have occurred, specifically in the Conscrypt
class.
Result:
Netty now builds and tests against Conscrypt 1.0.0.RC11
Motivation:
Netty is unable to use Java9s ALPN support atm.
Modifications:
When running on Java9+ we invoke the correct methods that are exposed on the Java9+ implementation of SSLEngine and so be able to support ALPN.
This patch is based on the work of @rschmitt and so https://github.com/netty/netty/pull/6992.
Result:
Fixes#6933.
Motivation:
Remove Unsafe dependency for Atomic queues in JCTools, resolved in version 2.1.0
Modification:
Change pom JCTools version
Result:
Fixes#7117
Motivation:
We recently changed netty-tcnative to use underscores in its native library names.
Modifications:
Update code to use underscores when loading native library.
Result:
More consistent code.
