Motivation:
NullChecks resulting in a NullPointerException or IllegalArgumentException, numeric ranges (>0, >=0) checks, not empty strings/arrays checks must never be anonymous but with the parameter or variable name which is checked. They must be specific and should not be done with an "OR-Logic" (if a == null || b == null) throw new NullPointerEx.
Modifications:
* import static relevant checks
* Replace manual checks with ObjectUtil methods
Result:
All checks needed are done with ObjectUtil, some exception texts are improved.
Fixes#11170
Motivation:
At the moment we only expose close(...) methods that take a Channel as paramater. This can be problematic as the write will start at the end of the pipeline which may contain ChannelOutboundHandler implementations that not expect WebSocketFrame objects. We should better also support to pass in a ChannelHandlerContext as starting point for the write which ensures that the WebSocketFrame objects will be handled correctly from this position of the pipeline.
Modifications:
- Add new close(...) methods that take a ChannelHandlerContext
- Add javadoc sentence to point users to the new methods.
Result:
Be able to "start" the close at the right position in the pipeline.
Motivation:
People may use the object serialisation example as a vehicle to test out sending their own objects across the wire.
If those objects are not actually serialisable for some reason, then we need to let the exception propagate so that this becomes obvious to people.
Modification:
Add a listener to the future that sends the first serialisable message, so that we ensure that any exceptions that shows up during serialisation becomes visible.
Without this, the state of the future that sent the first message was never checked or inspected anywhere.
Result:
Serialisation bugs in code derived from the Object Echo example are much easier to diagnose.
This fixes#10777
Motivation:
https in xmlns URIs does not work and will let the maven release plugin fail:
```

Modifications:
Use http for xmlns
Result:
Be able to use maven release plugin
Motivation:
HTTP is a plaintext protocol which means that someone may be able
to eavesdrop the data. To prevent this, HTTPS should be used whenever
possible. However, maintaining using https:// in all URLs may be
difficult. The nohttp tool can help here. The tool scans all the files
in a repository and reports where http:// is used.
Modifications:
- Added nohttp (via checkstyle) into the build process.
- Suppressed findings for the websites
that don't support HTTPS or that are not reachable
Result:
- Prevent using HTTP in the future.
- Encourage users to use HTTPS when they follow the links they found in
the code.
Motivation:
LGTM reports multiple issues. They need to be triaged,
and real ones should be fixed.
Modifications:
- Fixed multiple issues reported by LGTM, such as redundant conditions,
resource leaks, typos, possible integer overflows.
- Suppressed false-positives.
- Added a few testcases.
Result:
Fixed several possible issues, get rid of false alarms in the LGTM report.
Motivation:
MQTT Specification version 5 was released over a year ago,
netty-codec-mqtt should be changed to support it.
Modifications:
Added more message and header types in `io.netty.handler.codec.mqtt`
package in `netty-coded-mqtt` subproject,
changed `MqttEncoder` and `MqttDecoder` to handle them properly,
added attribute `NETTY_CODEC_MQTT_VERSION` to track protocol version
Result:
`netty-codec-mqtt` supports both MQTT5 and MQTT3 now.
Motivation:
Avoid keeping unused dependencies around.
Modification:
Remove all references to javassist dependency, since it does not appear to be used by anything.
Result:
One less dependency to worry about.
Motivation:
This request only has headers frame, it should set endOfStream flag, or
it will never get a response.
Modifications:
Set endOfStream=true in header frame.
Result:
Http2FrameClient can get a response now.
Motivation:
Current implementation `StompSubframeEncoder` can encode `StompFrame` into several separate chunks or encode separately `StompHeadersSubframe` and `StompContentSubframe`. But some client libraries (e.g. stomp.js) do not support aggregation.
Modification:
Add StompWebSocketFrameEncoder for integration between origin stomp suframe encoder and `ContinuationWebSocketFrame` to support chunks on transport level.
Result:
Fixes#10261
Motivation:
[DNS-over-TLS (DoT)](https://tools.ietf.org/html/rfc7858.html) encrypts DNS queries and sends it over TLS connection to make sure queries are secure in transit.
[TCP DNS](https://tools.ietf.org/html/rfc7766) sends DNS queries over TCP connection (unencrypted).
Modification:
Add DNS-over-TLS (DoT) Client Example which uses TLSv1.2 and TLSv1.3.
Add TCP DNS Client Example
Result:
DNS-over-TLS (DoT) Client Example
TCP DNS Client Example
