Motivation:
We can use the diamond operator these days.
Modification:
Use diamond operator whenever possible.
Result:
More modern code and less boiler-plate.
Motivation:
Since Java 7 we can automatically close resources in try () construction.
Modification:
Changed all try catches in the code with autoclose try (resource)
Result:
Less boiler-plate
Motiviation:
Because of how we implemented the registration / deregistration of an EventLoop it was not possible to wrap an EventLoop implementation and use it with a Channel.
Modification:
- Introduce EventLoop.Unsafe which is responsible for the actual registration.
- Move validation of EventLoop / Channel combo to the EventLoop
- Add unit test that verifies that wrapping works
Result:
Be able to wrap an EventLoop and so add some extra functionality.
Motivation:
ByteBuf supports “marker indexes”. The intended use case for these is if a speculative operation (e.g. decode) is in process the user can “mark” and interface and refer to it later if the operation isn’t successful (e.g. not enough data). However this is rarely used in practice,
requires extra memory to maintain, and introduces complexity in the state management for derived/pooled buffer initialization, resizing, and other operations which may modify reader/writer indexes.
Modifications:
Remove support for marking and adjust testcases / code.
Result:
Fixes https://github.com/netty/netty/issues/8535.
Motivation:
Most of the maven modules do not explicitly declare their
dependencies and rely on transitivity, which is not always correct.
Modifications:
For all maven modules, add all of their dependencies to pom.xml
Result:
All of the (essentially non-transitive) depepdencies of the modules are explicitly declared in pom.xml
Motivation:
This transport is unique because it uses Java's blocking IO (java.io / java.net) under the hood. However it is not clear if this transport is actually useful so it should be removed.
Modifications:
- Remove OIO transport and RXTX transport which depend on it.
- Remove Oio*Sctp* implementations
- Remove PerThreadEventLoop* which was only used by OIO transport.
Result:
Fixes https://github.com/netty/netty/issues/8510.
Motivation:
We currently depend on slf4j in an transitive way in one of our classes in the examples. We should not do this.
Modifications:
Remove logging in example.
Result:
Remove not needed dependency.
Motivation:
The UDT transport was marked as @Deprecated a long time ago as the underlying native library is not really maintained anymore. We should remove it as part of Netty 5.
Modifications:
Remove UDT transport
Result:
Dont try to maintain a transport which uses an unmaintained native lib internally.
Motivation:
After #7527 fix there is no need to manually release chunks (HttpData) during file upload as they will be released on HttpPostRequestDecoder.destroy().
Modification:
HttpUploadServer example doesn't release chunks manually (doesn't call data.release()).
Result:
Fixes#7695 and #7689
Motivation:
MemcacheClientHandler.channelRead(...) need to release the frame after it prints out its content to not introduce a memory leak.
Modifications:
Call release() on the frame.
Result:
Example has no leak any more.
Motivation:
We need to release the inbound data to ensure there are no leaks.
Modifications:
Extend SimpleChannelInboundHandler which will release inbound data by default.
Result:
No more leaks.
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:
At the moment we use a ByteBuf as the payload for a http2 frame. This complicates life-time management a lot with no real gain and also may produce more objects then needed. We should just use a long as it is required to be 8 bytes anyway.
Modifications:
Use long for ping payloads.
Result:
Fixes [#7629].
Motivation:
Even if it's a super micro-optimization (most JVM could optimize such
cases in runtime), in theory (and according to some perf tests) it
may help a bit. It also makes a code more clear and allows you to
access such methods in the test scope directly, without instance of
the class.
Modifications:
Add 'static' modifier for all methods, where it possible. Mostly in
test scope.
Result:
Cleaner code with proper 'static' modifiers.
