Motivation:
"Connection: close" header should be specified each time we're going
to close an underlying TCP connection when sending HTTP/1.1 reply.
Modifications:
Introduces changes made in #8914 for the following examples:
* WebSocket index page and WebSocket server handler
* HelloWorld server
* SPDY server handler
* HTTP/1.1 server handler from HTTP/2 HelloWorld example
* HTTP/1.1 server handler from tiles example
Result:
Keep-Alive connections management conforms with RFCs.
Motivation:
We can just use a local variable in HttpUploadServerHandler and so make the example code a bit cleaner.
Modifications:
Use local variable.
Result:
Fixes https://github.com/netty/netty/issues/8892.
Motivation:
Simple rules:
* close the connection when sending any error
* specify "Connection: close" header when closing the connection
* successful responses should keep the connection intact when otherwise is not requested by the client
Modifications:
* "send response and cleanup the connection" logic moved to a helper
* for all successful responses set "Content-Lenght" header
* do not specify "Connection: Keep-Alive" header as far it's a default for HTTP/1.1
* set "Connection: close" header when necessary
Result:
Keep-Alive connections management is inlined with RFCs.
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:
In most cases, HttpMethod instance is built from the factory method and the same instance is taken for known Http Methods. So we can implement fast path for equals().
Modification:
Replace == checks with HttpMethod.equals;
Use this == o within HttpMethod.equals;
Replaced known new HttpMethod with HttpMethod.valueOf;
Result:
Comparisons should be a bit faster in some cases.
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:
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:
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:
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].
