Motivation:
Projects may import multiple libraries which use different versions of Netty.
Modifications:
Add 'netty-bom' meta-project that contains the other projects in a dependencyManagement section.
Result:
Developers can import the BOM to enforce specific version of Netty.
Motivation:
We not support all SSLParameters settings so we should better throw if a user try to use them.
Modifications:
- Check for unsupported parameters
- Add unit test
Result:
Less surprising behavior.
Motivation:
We should move the AutobahnTestsuite to an extra module. This allows easier to run only the testsuite or only the autobahntestsuite
Modifications:
Create a new module (testsuite-autobahn)
Result:
Better project structure.
Motivation:
autobahntestsuite-maven-plugin 0.1.4 was released and supports Java9.
Modifications:
Update plugin to be able to run tests on Java9
Result:
Autobahntestsuite can also be run on Java9.
Motivation:
OpenSSL doesn't automatically verify hostnames and requires extract method calls to enable this feature [1]. We should allow this to be configured.
Modifications:
- SSLParamaters#getEndpointIdentificationAlgorithm() should be respected and configured via tcnative interfaces.
Result:
OpenSslEngine respects hostname verification.

Motivation:
We have our own ThreadLocalRandom implementation to support older JDKs . That said we should prefer the JDK provided when running on JDK >= 7
Modification:
Using ThreadLocalRandom implementation of the JDK when possible.
Result:
Make use of JDK implementations when possible.
Motivation:
We missed some stuff in 5728e0eb2c and so the build failed on java9
Modifications:
- Add extra cmdline args when needed
- skip the autobahntestsuite as jython not works with java9
- skip the osgi testsuite as the maven plugin not works with java9
Result:
Build finally passed on java9
Motivation:
Commit 591293bfb4 changed the build to need java8 but missed to adjust the enforce rule as well.
Modifications:
Enforce java8+
Result:
Quickly fail when user tries to compile with pre java8
Motivation:
Java8 is out now for some time and JDK7 is no longer supported officially. We should remove all our backports and just use what the JDK provides us. This also will allow us to use intrinsics that are offered by the JDK implementations.
Modifications:
Remove all backports of jdk8 classes.
Result:
Use what the JDK offers us. This also fixes [#5458]
Motivation:
tcnative was moved into an internal package.
Modifications:
Update package for tcnative imports.
Result:
Use correct package names for tcnative.
Motivation:
We need to pass special arguments to run with jdk9 as otherwise some tests will not be able to run.
Modifications:
Allow to define extra arguments when running with jdk9
Result:
Tests pass with jdk9
Motivation:
As we now need to compile with java8 we should still allow to run the tests with a different java version to ensure everythin also works with java 7 and 6.
Modifications:
Allow to pass "-DtestJavaHome" to the build and so use a different java version during running the tests.
Result:
Be able to run tests with different java versions.
Motivation:
tcnative has updated how constants are defined and removed some constants which are either obsolete or now set directly in tcnative.
Modifications:
- update to compile against tcnative changes.
Result:
Netty compiles with tcnative options changes.
Motivation:
Currently Netty utilizes BIO_new_bio_pair so we can control all FD lifetime and event notification but delegates to OpenSSL for encryption/decryption. The current implementation sets up a pair of BIO buffers to read/write encrypted/plaintext data. This approach requires copying of data from Java ByteBuffers to native memory BIO buffers, and also requires both BIO buffers to be sufficiently large to hold application data. If direct ByteBuffers are used we can avoid coyping to/from the intermediate BIO buffer and just read/write directly from the direct ByteBuffer memory. We still need an internal buffer because OpenSSL may generate write data as a result of read calls (e.g. handshake, alerts, renegotiation, etc..), but this buffer doesn't have to be be large enough to hold application data.
Modifications:
- Take advantage of the new ByteBuffer based BIO provided by netty-tcnative instead of using BIO_read and BIO_write.
Result:
Less copying and lower memory footprint requirement per TLS connection.
Motivation:
We used various mocking frameworks. We should only use one...
Modifications:
Make usage of mocking framework consistent by only using Mockito.
Result:
Less dependencies and more consistent mocking usage.
Motivation:
Previous versions of netty-tcnative used the org.apache.tomcat namespace which could lead to problems when a user tried to use tomcat and netty in the same app.
Modifications:
Use netty-tcnative which now uses a different namespace and adjust code to some API changes.
Result:
Its now possible to use netty-tcnative even when running together with tomcat.
Motivation:
We need to update jetty-alpn-agent to support latest JDK releases.
Modifications:
Update jetty-alpn-agent to 2.0.6
Result:
Be able to run tests with latest JDK releases.
Motivation:
When an empty hostname is used in DnsNameResolver.resolve*(...) it will never notify the future / promise. The root cause is that we not correctly guard against errors of IDN.toASCII(...) which will throw an IllegalArgumentException when it can not parse its input. That said we should also handle an empty hostname the same way as the JDK does and just use "localhost" when this happens.
Modifications:
- If the try to resolve an empty hostname we use localhost
- Correctly guard against errors raised by IDN.toASCII(...) so we will always noify the future / promise
- Add unit test.
Result:
DnsNameResolver.resolve*(...) will always notify the future.
Motivation:
Openssl provider should behave same as JDK provider when mutual authentication is required and a specific set of trusted Certificate Authorities are specified. The SSL handshake should return back to the connected peer the same list of configured Certificate Authorities.
Modifications:
Correctly set the CA list.
Result:
Correct and same behaviour as the JDK implementation.
Motivation:
Often its useful to run the tests with different commandline arguments (like different system properties).
Modifications:
Introduce argLine.javaProperties which can be set from the commandline as well to add arguments that should be append when run the unit tests.
Result:
More flexible way to run the tests.
Motivation:
Java9 will be released soon so we should ensure we can compile netty with Java9 and run all our tests. This will help to make sure Netty will be usable with Java9.
Modification:
- Add some workarounds to be able to compile with Java9, note that the full profile is not supported with Java9 atm.
- Remove some usage of internal APIs to be able to compile on java9
- Not support Alpn / Npn and so not run the tests when using Java9 for now. We will do a follow up PR to add support.
Result:
Its possible to build netty and run its testsuite with Java9.
Motivation:
We tried to detect the correct alert to use depending on the CertificateException that is thrown by the TrustManager. This not worked all the time as depending on the TrustManager implementation it may also wrap a CertPathValidatorException.
Modification:
- Try to unwrap the CertificateException if needed and detect the right alert via the CertPathValidatorException.
- Add unit to verify
Result:
Send the correct alert depending on the CertificateException when using OpenSslEngine.
Motivation:
A new version of centos was released we should verify against it when release.
Modifications:
Bump up version.
Result:
Release on latest centos version.
Motivation:
Add test-case for doing mutal auth with a certificate chain that holds more then one certificate.
Modifications:
Add test case
Result:
more tests.
Motivation:
For the leak profile we attempted to increase the number of leak hints that were retained to make debugging easier, but there was a typo.
Modifications:
- maxRecord -> maxRecords
Result:
Fix typo in pom.xml so leak profile provides more context for leaks.
Motivation:
Since netty shaded JCTools the OSGi manifest no longer is correct. It claims to
have an optional import "org.jctools.queues;resolution:=optional,org.jctools.qu
eues.atomic;resolution:=optional,org.jctools.util;resolution:=optional"
However since it is shaded, this is no longer true.
This was noticed when making JCTools a real bundle and netty resolved it as
optional import.
Modifications:
Modify the generated manifest by no longer analyzing org.jctools for imports.
A manual setting of sun.misc as optional was required.
Result:
Netty OSGi bundle will no longer interfere with a JCTools bundle.
Motivation:
We need to ensure we not set duplicated certificates when using OpenSslEngine.
Modifications:
- Skip first cert in chain when set the chain itself and so not send duplicated certificates
- Add interopt unit tests to ensure no duplicates are send.
Result:
No more duplicates.
Motiviation:
Previously the way how CertificateRequestCallback was working had some issues which could cause memory leaks and segfaults. Due of this tcnative code was updated to change the signature of the method provided by the interface.
Modifications:
Update CertificateRequestCallback implementations to match new interface signature.
Result:
No more segfaults / memory leaks when using boringssl or openssl >= 1.1.0
Motivation:
We use often javachannel().socket().* in NIO as these methods exists in java6. The problem is that these will throw often very general Exceptions (Like SocketException) while it is more expected to throw the Exceptions listed in the nio interfaces. When possible we should use the new methods available in java7+ which throw the correct exceptions.
Modifications:
Check for java version and depending on it using the socket or the javachannel.
Result:
Throw expected Exceptions.
Motivation:
netty-tcnative API has changed to remove a feature that contributed to a memory leak.
Modifications:
- Update to use the modified netty-tcnative API
Result:
Netty can use the latest netty-tcnative.
