Motivation:
We have a utility method to check for > 0 and >0 arguments. We should use it.
Modification:
use checkPositive/checkPositiveOrZero instead of if statement.
Result:
Re-use utility method.
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:
31fd66b617 added @Deprecated to some classes but also to the package-info.java files. IntelliJ does not like to have these annotations on package-info.java
Modifications:
Remove annotation from package-info.java
Result:
Be able to compile against via IntelliJ
Motivation:
We plan to remove the OIO based transports in Netty 5 so we should mark these as deprecated already.
Modifications:
Mark all OIO based transports as deprecated.
Result:
Give the user a heads-up for removal.
Motivation
There is a cost to concatenating strings and calling methods that will be wasted if the Logger's level is not enabled.
Modifications
Check if Log level is enabled before producing log statement. These are just a few cases found by RegEx'ing in the code.
Result
Tiny bit more efficient code.
Motivation:
Some `if` statements contains common parts that can be extracted.
Modifications:
Extract common parts from `if` statements.
Result:
Less code and bytecode. The code is simpler and more clear.
Motivation:
SctpMessageCompletionHandler stores fragments in a Map but not release the stored ByteBuf when the handler is removed.
Modifications:
Release all buffers that are still in the Map when handlerRemoved(...) is called.
Result:
No more leaks for fragemented messages.
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.
Motivation:
The first parameter of SctpMessage is protocolIdentifier, and the second is streamIdentifier. So we need to swap the parameters in encode method
Modification:
Fix order
Result:
SctpOutboundByteStreamHandler works correctly.
Motivation:
Avoid multiple search in fragments map
Modifications:
Replace usage of Map.containsKey by Map.remove
Result:
During packet process, fragment is only search once in the map instead of 3 times in the previous worst case
Motivation:
For use cases that demand frequent updates of the write watermarks, an
API that requires immutable WriteWaterMark objects is not ideal, as it
implies a lot of object allocation.
For example, the HTTP/2 child channel API uses write watermarks for outbound
flow control and updates the write watermarks on every DATA frame write.
Modifications:
Remote @Deprecated tag from primitive getters and setters, however the corresponding
channel options remain deprecated.
Result:
Primitive getters and setters for write watermarks are no longer marked @Deprecated.
Motivation:
The SCTP_INIT_MAXSTREAMS property is ignored on NioSctpServerChannel / OioSctpServerChannel.
Modifications:
- Correctly use the netty ChannelOption
- Ensure getOption(...) works
- Add testcase.
Result:
SCTP_INIT_MAXSTREAMS works.
Conflicts:
transport-sctp/src/main/java/io/netty/channel/sctp/DefaultSctpServerChannelConfig.java
Motivation:
JCTools supports both non-unsafe, unsafe versions of queues and JDK6 which allows us to shade the library in netty-common allowing it to stay "zero dependency".
Modifications:
- Remove copy paste JCTools code and shade the library (dependencies that are shaded should be removed from the <dependencies> section of the generated POM).
- Remove usage of OneTimeTask and remove it all together.
Result:
Less code to maintain and easier to update JCTools and less GC pressure as the queue implementation nt creates so much garbage
