Motivation:
Netty currently doesn't build and distribute the test JARs. Having easy access to the test JARs would enable downstream projects (such as GraalVM) to integrate the Netty unit tests in their CI pipeline to ensure continous compatibility with Netty features. The alternative would be to build Netty from source every time to obtain the test jars, however, depending on the CI setup, that may not always be possible.
Modifications:
Modify `pom.xml` to enable generation of test JARs and corresponding source JARs.
Result:
Running the Maven build will create the test JARs and corresponding source JARs. This change was tested locally via `mvn install` and the test JARs are correctly copied under the Maven cache. The expectation is that running `mvn deploy` will also copy the additional JARs to the maven repository.
Motivation:
On MacOS it is not really good enough to check /etc/resolv.conf to determine the nameservers to use. We should retrieve the nameservers using the same way as mDNSResponser and chromium does by doing a JNI call.
Modifications:
Add MacOSDnsServerAddressStreamProvider and testcase
Result:
Use correct nameservers by default on MacOS.
Motivation:
Netty is an asynchronous framework.
If somebody uses a blocking call inside Netty's event loops,
it may lead to a severe performance degradation.
BlockHound is a tool that helps detecting such calls.
Modifications:
This change adds a BlockHound's SPI integration that marks
threads created by Netty (`FastThreadLocalThread`s) as non-blocking.
It also marks some of Netty's internal methods as whitelisted
as they are required to run the event loops.
Result:
When BlockHound is installed, any blocking call inside event loops
is intercepted and reported (by default an error will be thrown).
Motivation:
We can use the `@SuppressJava6Requirement` annotation to be more precise about when we use Java6+ APIs. This helps us to ensure we always protect these places.
Modifications:
Make use of `@SuppressJava6Requirement` explicit
Result:
Fixes https://github.com/netty/netty/issues/2509.
Motivation:
We should use the latest commons-compress release to fix CVE-2019-12402 (even it is only a test dependency)
Modifications:
Update commons-compress to 1.19
Result:
Fix security alert
Motivation:
It is not possible to build Netty on an s390_64 platform.
Modifications:
Modify pom.xml so that s390_64 is acceptable as os.detected.arch.
Result:
Netty can be built on an s390_64 platform.
Signed-off-by: Tatsushi Inagaki <e29253@jp.ibm.com>
Motivation:
We just released a new version of netty-tcnative.
Modifications:
Bump up to netty-tcnative 2.0.26.Final
Result:
Use latest netty-tcnative release
Motivation:
At the moment it is not possible to build netty on a power 8 systems.
Modifications:
- Improve detection of the possibility of using Conscrypt
- Skip testsuite-shading when not on x86_64 as this is the only platform for which we build tcnative atm
- Only include classifier if on x86_64 for tcnative as dependency as this is the only platform for which we build tcnative atm
- Better detect if UDT test can be run
Result:
Fixes https://github.com/netty/netty/issues/9479
Motivation:
Users' runtime systems may have incompatible dynamic libraries to the ones our
tcnative wrappers link to. Unfortunately, we cannot determine and catch these
scenarios (in which the JVM crashes) but we can make a more educated guess on
what library to load and try to find one that works better before crashing.
Modifications:
1) Build dynamically linked openSSL builds for more OSs (netty-tcnative)
2) Load native linux libraries with matching classifier (first)
Result:
More developers / users can use the dynamically-linked native libraries.
Motivation:
Since both projects (to some extend) rely on classifier parsing via the
os-maven-plugin, they should ideally use the same version in case the parsing
changed.
Modifications:
Upgrade os-maven-plugin from 1.6.0 to 1.6.2
Result:
Same os-maven-plugin with same parsing logic.
Motivation:
Netty homepage(netty.io) serves both "http" and "https".
It's recommended to use https than http.
Modification:
I changed from "http://netty.io" to "https://netty.io"
Result:
No effects.
Motivation:
The first final version of GraalVM was released which deprecated some flags. We should use the new ones.
Modifications:
Removes the use of deprecated GraalVM native-image flags
Adds a flag to initialize netty at build time.
Result:
Do not use deprecated flags
Motivation:
When trying to use graalvm and build netty we currently fail because our build configuration is not compatible with it.
Modification:
- Skip plugins that are not supported when graal is used
- Correctly configure surefire plugin for graal so it not produces a NPE
Result:
We can build and test with graalvm.
Motivation:
GraalVM native images are a new way to deliver java applications. Netty is one of the most popular libraries however there are a few limitations that make it impossible to use with native images out of the box. Adding a few metadata (in specific modules will allow the compilation to success and produce working binaries)
Modification:
Added properties files in `META-INF` and substitutions classes (under `internal.svm`) will solve the compilation issues. The substitutions classes are not visible and do not have a public constructor so they are not visible to end users.
Result:
Fixes#8959
This fix is very conservative as it applies the minimum config required to build:
* pure netty servers
* vert.x applications
* grpc applications
The build is having trouble due to checkstyle which does not seem to be able to find the copyright notice on property files.
Motivation:
We should update to netty-tcnative 2.0.25.Final as it fixes a possible segfault on systems that use openssl < 1.0.2 and for which we compiled with gcc.
See https://github.com/netty/netty-tcnative/pull/457
Modifications:
Update netty-tcnative
Result:
No more segfault possible.
Motivation:
4079189f6b changed the dependency to netty-tcnative-borinssl-static but it should still be netty-tcnative.
Modifications:
Change back to netty-tcnative
Result:
Correct dependency is used
Motivation:
BoringSSL allows to customize the way how key signing is done an even offload it from the IO thread. We should provide a way to plugin an own implementation when BoringSSL is used.
Modifications:
- Introduce OpenSslPrivateKeyMethod that can be used by the user to implement custom signing by using ReferenceCountedOpenSslContext.setPrivateKeyMethod(...)
- Introduce static methods to OpenSslKeyManagerFactory which allows to create a KeyManagerFactory which supports to do keyless operations by let the use handle everything in OpenSslPrivateKeyMethod.
- Add testcase which verifies that everything works as expected
Result:
A user is able to customize the way how keys are signed.
Motivation:
com.puppycrawl.tools checkstyle < 8.18 was reported to contain a possible security flaw. We should upgrade.
Modifications:
- Upgrade netty-build and checkstyle.
- Fix checkstyle errors
Result:
Fixes https://github.com/netty/netty/issues/8968.
Motivation:
We had a bug which could case ExtendedSSLSession.getPeerSupportedSignatureAlgorithms() return an empty array when using BoringSSL. This testcase verifies we correctly return algorithms after the fix in https://github.com/netty/netty-tcnative/pull/449.
Modifications:
Add testcase to verify behaviour.
Result:
Ensure we correctly retuen the algorithms.
Motivation:
https://github.com/netty/netty/pull/8963 adds property files which contains a netty copyright header but our old checkstyle regex did not correct detect these.
Modifications:
Update to new netty-build which contains an updated regex.
Result:
Be able to correctly detect copyright headers in property files.
Motivation:
We want to make the experience as smooth as possible for our users when using Java9+ and so should ensure we do not produce any 'Illegal reflective access' errors when using netty.
Modifications:
Add jvmArgs when running our tests that will deny reflective access and so will fail the build at the end due not be able to load some classes.
Result:
Ensure we do not produce any illegal refelctive access errors when using java9+
Motivation:
SSLEngine API has a notion of tasks that may be expensive and offload these to another thread. We did not support this when using our native implementation but can now for various operations during the handshake.
Modifications:
- Support offloading tasks during the handshake when using our native SSLEngine implementation
- Correctly handle the case when NEED_TASK is returned and nothing was consumed / produced yet
Result:
Be able to offload long running tasks from the EventLoop when using SslHandler with our native SSLEngine.
Motivation:
Netty is very widely used which can lead to a lot of pain when we break API / ABI. We should make use japicmp-maven-plugin during the build to verify we do not introduce breakage by mistake.
Modifications:
- Add japicmp-maven-plugin to the build process
- Fix a method signature change in HttpProxyHandler that was flagged as a possible problem.
Result:
Ensure no API/ABI breakage accour between releases.
Motivation:
We need to update to a new checkstyle plugin to allow the usage of lambdas.
Modifications:
- Update to new plugin version.
- Fix checkstyle problems.
Result:
Be able to use checkstyle plugin which supports new Java syntax.
Motivation:
Since the updating to OpenJDK 11.0.2 the OSGI testsuite fails. We should dissable it until there is a version of the used plugins that works with this OpenJDK version.
Modifications:
Skip osgi testsuite when using JDK11.
Result:
Build pass again with JDK11.
Motivation:
There are the first EA bulds for OpenJDK 13. We should support to build with it and run builds on the CI.
Modifications:
- Add profile for JDK 13
- Add docker config to run with JDK 13.
Result:
Building and testing with OpenJDK 13 is possible.
Motivation:
We should use the latest OpenJDK 12 release when running tests against Java12.
Modifications:
- Update to OpenJDK 12 ea22.
- Update pax exam version
- skip OSGI testsuite on Java12 as it does not work ea22 yet.
Result:
Use latest OpenJDK 12 version when running on the CI.
