Motivation:
Some SingleEventLoop implementations may need some "time" to update the number of registered Channels. We should loop until we see the correct value or timeout if we did not observe the correct value.
Modifications:
- Loop until we see the correct value
- add test timeout
Result:
Fixes https://github.com/netty/netty/issues/11169
Motivation:
When create a WebSocketServerProtocolConfig to check URI path starts from '/',
only '/' or '//subPath' can be passed by the checker,but '/subPath' should be
passed as well
Modifications:
in `WebSocketServerProtocolHandshakeHandler.isWebSocketPath()` treat '/' a special case
Result:
'/subPath' can be passed
Motivation:
In the latest version of BouncyCastle, BCJSSE:'TLSv1.3' is now a supported protocol for both client and server. So should consider enabling TLSv1.3 when TLSv1.3 is available
Modification:
This pr is to enable TLSv1.3 when using BouncyCastle ALPN support, please review this pr,thanks
Result:
Enable TLSv1.3 when using BouncyCastle ALPN support

Motivation:
RFC 8411 defines a new HTTP/2 pseudo header called `:protocol`:
- https://datatracker.ietf.org/doc/rfc8441/
Netty currently raises an exception when validating an `Http2Headers`.
Modifications:
- Added `Http2Headers.PseudoHeaderNames.PROTOCOL` so that `:protocol`
pseudo header is not rejected.
Result:
- A user can implement WebSockets with HTTP/2.

Motivation:
Under Android it was not possible to load a specific web page. It might be related to the (missing?) ALPN of the internal TLS implementation. BouncyCastle as a replacement works but this was not supported so far by Netty.
BouncyCastle also has the benefit to be a pure Java solution, all the other providers (OpenSSL, Conscrypt) require native libraries which are not available under Android at least.
Modification:
BouncyCastleAlpnSslEngine.java and support classes have been added. It is relying on the JDK code, hence some support classes had to be opened to prevent code duplication.
Result:
BouncyCastle can be used as TLS provider.

Motivation:
In the method processHeaderState(), we have checked the http2 payload length against max frame size. But later for
different types of frames, we checked this again.
Modifications:
Removed the duplicate check in verify*() methods. And removed verifyPayloadLength() method, since it will not be used anymore.
Result:
Remove duplicate check and make the code cleaner.
Motivation: We have already calculated the payload length. So no need to calculate again when allocating ByteBuf
Modification: Used payloadLength variable instead of calculating the payload length again
Result: Re-use the variable value and make the code cleaner
Motivation:
While adding support for GRO (b05fdf3ff8) we broke support for IP_RECVORIGDSTADDR when using the native transport. Beside this we also didnt correctly handle IP_RECVORIGDSTADDR when recvmmsg was used.
Modifications:
- Fix support for IP_RECVORIGDSTADDR when using the native epoll transport for normal reads (recvmsg) but also for scattering reads (recvmmsg)
- Remove code from unix code-base as the support is linux specific and we not need the code there anymore
Result:
Fixes https://github.com/netty/netty/issues/11141
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:
On Windows DnsNameResolver is not able to resolve the host(computer) name as it is not in the hosts file and the DNS server is also not able to resolve it.

The bug should come from the way that `StreamBufferingEncoder.writeHeaders()` handles the condition `connection().goAwayReceived()`. The current behavior is to delegate to `super.writeHeaders()` and let the stream fail, but this will end up with `Http2Exception` with the message "Maximum active streams violated for this endpoint" which is horrible. See e5951d46fc/codec-http2/src/main/java/io/netty/handler/codec/http2/StreamBufferingEncoder.java (L152-L155)
Modification:
Abort new stream immediately if goaway received *and* MAX_CONCURRENT_STREAM reached in `StreamBufferingEncoder` rather than delegating to the `writeHeaders()` method of its super class.
Result:
In the situation when GOAWAY received as well as MAX_CONCURRENT_STREAM exceeded, the client will fail the buffered streams with `Http2Error.NO_ERROR` and message "GOAWAY received" instead of "Maximum active streams violated for this endpoint".

Motivation:
`ThreadLocalRandom` doesn't cause contention. Also `nextInt()` generates only 4 random bytes while `Math.random()` generates 8 bytes.
Modification:
Replaced `(int) Math.random()` with `PlatformDependent.threadLocalRandom().nextInt()`
Result:
No possible contention when random numbers for WebSockets.
Motivation:
We are increasingly running in environments where Unsafe, setAccessible, etc. are not available.
When debug logging is enabled, we log a complete stack trace every time one of these initialisations fail.
Seeing these stack traces can cause people unnecessary concern.
For instance, people might have alerts that are triggered by a stack trace showing up in logs, regardless of its log level.
Modification:
We continue to print debug log messages on the result of our initialisations, but now we only include the full stack trace is _trace_ logging (or FINEST, or equivalent in whatever logging framework is configured) is enabled.
Result:
We now only log these initialisation stack traces when the lowest possible log level is enabled.
Fixes#7817
Motivation:
SslHandler invokes channel.read() during the handshake process. For some
channel implementations (e.g. LocalChannel) this may result in re-entry
conditions into unwrap. Unwrap currently defers updating the input
buffer indexes until the unwrap method returns to avoid intermediate
updates if not necessary, but this may result in unwrapping the same
contents multiple times which leads to handshake failures [1][2].
[1] ssl3_get_record:decryption failed or bad record mac
[2] ssl3_read_bytes:sslv3 alert bad record mac
Modifications:
- SslHandler#unwrap updates buffer indexes on each iteration so that if
reentry scenario happens the correct indexes will be visible.
Result:
Fixes https://github.com/netty/netty/issues/11146
Motivation:
When Memory based Factory is used, if the first chunk starts with Line Break, the HttpData
is not filled with the current available buffer if the delimiter is not found yet, while it may
add some.
Fix JavaDoc to note potential wrong usage of content() or getByteBuf() if HttpDatais has
a huge content with the risk of Out Of Memory Exception.
Fix JavaDoc to explain how to release properly the Factory, whatever it is in Memory,
Disk or Mixed mode.
Fix issue #11143
Modifications:
First, when the delimiter is not found, instead of searching Line Break from readerIndex(), we should search
from readerIndex() + readableBytes() - delimiter size, since this is the only part where usefull
Line Break could be searched for, except if readableBytes is less than delimiter size (then we search from
readerIndex).
Second, when a Memory HttpData is created, it should be assigned an empty buffer to be
consistent with the other implementations (Disk or Mixed mode).
We cannot change the default behavior of the content() or getByteBuf() of the Memory based HttpData
since the ByteBuf is supposed to be null when released, but not empty.
When a new ByteBuf is added, one more check verifies if the current ByteBuf is empty, and if so, it
is released and replaced by the new one, without creating a new CompositeByteBuf.
Result:
In the tests testBIgFileUploadDelimiterInMiddleChunkDecoderMemoryFactory and related for other modes,
the buffers are starting with a CRLF.
When we offer only the prefix part of the multipart (no data at all), the current Partial HttpData has
an empty buffer.
The first time we offer the data starting with CRLF to the decoder, it now
has a correct current Partial HttpData with a buffer not empty.
The Benchmark was re-run against this new version.

So +20 to +40% improvement due to not searching for CRLF/LF into the full buffer when no delimiter is found,
but only from the end and delimiter size + 2 (CRLF).
Motivation:
SslHandler has many independent boolean member variables. They can be
collapsed into a single variable to save memory.
Modifications:
- SslHandler boolean state consolidated into a single short variable.
Result:
Savings of 8 bytes per SslHandler (which is per connection) observed on
OpenJDK.
Motivation:
`SslHandler#unwrap` may produce `SslHandshakeCompletionEvent` if it
receives `close_notify` alert. This alert indicates that the engine is
closed and no more data are expected in the pipeline. However, it fires
the event before the last data chunk. As the result, further handlers
may loose data if they handle `SslHandshakeCompletionEvent`.
This issue was not visible before #11133 because we did not write
`close_notify` alert reliably.
Modifications:
- Add tests to reproduce described behavior;
- Move `notifyClosePromise` after fire of the last `decodeOut`;
Result:
`SslHandshakeCompletionEvent` correctly indicates that the engine is
closed and no more data are expected on the pipeline.
Motivation:
We should avoid blocking in the event loop as much as possible.
The InputStream.read() is a blocking method, and we don't need to call it if available() returns a positive number.
Modification:
Bypass calling InputStream.read() if available() returns a positive number.
Result:
Fewer blocking calls in the event loop, in general, when ChunkedStream is used.
Motivation:
SslHandler's wrap method notifies the handshakeFuture and sends a
SslHandshakeCompletionEvent user event down the pipeline before writing
the plaintext that has just been wrapped. It is possible the application
may write as a result of these events and re-enter into wrap to write
more data. This will result in out of sequence data and result in alerts
such as SSLV3_ALERT_BAD_RECORD_MAC.
Modifications:
- SslHandler wrap should write any pending data before notifying
promises, generating user events, or anything else that may create a
re-entry scenario.
Result:
SslHandler will wrap/write data in the same order.
Motivation:
This is a regression caused by #11086
Modifications:
AbstractKQueueChannel#writeFilter should be invoked with `!in.isEmpty()`
- false - all messages are written
- true - there are still messages to be written
Result:
AbstractKQueueChannel#writeFilter is invoked with the correct boolean depending on the ChannelOutboundBuffer state
Motivation:
We should skip the deployment of jars that are not meant to be consumed by the user as there is no public API.
Modifications:
Let's skip deployment for modules that are not useful for users
Result:
Build cleanup
Motivation:
We also need to compile the modules we depend on when finish up the release otherwise it may fail.
Modifications:
Add "-am" to the mvn args
Result:
Correctly also compile the modules we depend on
Motivation:
We also need to ensure that all the header validation is done when a single header with the endStream flag is received
Modifications:
- Adjust code to always enforce the validation
- Add more unit tests
Result:
Always correctly validate
Motivation:
As we can supported SegmentedDatagramPacket in multiple native
transports (like in epoll and io_uring) we should just move it to
unix-common so we can share code.
Modification:
- Move SegmentedDatagrampPacket to transport-native-unixu
- Mark the SegmentedDatagramPacket in epoll as deprecated
- Update code to use updated package.
Result:
Possibility of code re-use
Motivation:
There are some redundant checks and so these can be removed
Modifications:
- First check frameOpcode != OPCODE_PING is removed because the code executed int the branch where frameOpcode <= 7, while OPCODE_PING is 9.
- Second check frameOpcode != OPCODE_PING is removed because its checked before.
Result:
Code cleanup
Motivation:
UDP_GRO can improve performance when reading UDP datagrams. This patch adds support for it.
See https://lwn.net/Articles/768995/
Modifications:
- Add recvmsg(...)
- Add support for UDP_GRO in recvmsg(...) and recvmmsg(...)
- Remove usage of recvfrom(...) and just always use recvmsg(...) or recvmmsg(...) to simplify things
- Refactor some code for sharing
- Add EpollChannelOption.UDP_GRO and the getter / setter in EpollDatagramConfig
Result:
UDP_GRO is supported when the underlying system supports it.
Motivation:
We had a bug in out DefaulThreadFactory as it always retrieved the ThreadGroup to used during creation time when now explicit ThreadGroup was given. This is problematic as the Thread may die and so the ThreadGroup is destroyed even tho the DefaultThreadFactory is still used.

Modifications:
- If the user dont specify a ThreadGroup we will just pass null to the constructor of FastThreadLocalThread and so let it retrieve on creation time
- Adjust tests
Result:
Don't risk to see IllegalThreadStateExceptions.
netty-jni-util 0.0.2.Final is incompatible with static linking. Before
the netty-jni-util dependency was introduced netty-tcnative supported
static linking via NETTY_BUILD_STATIC. netty-jni-util 0.0.3.Final adds
static linking compatibility.
Modifications:
Bump netty-jni-util to version 0.0.3.Final and update to its new API
which requires the caller to manage packagePrefix.
Result:
Using latest version of netty-jni-util and restored static linking
compatibility.
Motivation:
LSE (https://mysqlonarm.github.io/ARM-LSE-and-MySQL/) can have a huge performance difference. Let's ensure we use a compiler that can support it.
Modifications:
Update to gc10 when cross-compiling as it supports LSE and enables it by default
Result:
More optimized builds for aarch64
