540c26bb56 HTTP/2 Ensure default settings are correctly enforced and interfaces clarified
Motivation:
The responsibility for retaining the settings values and enforcing the settings constraints is spread out in different areas of the code and may be initialized with different values than the default specified in the RFC. This should not be allowed by default and interfaces which are responsible for maintaining/enforcing settings state should clearly indicate the restrictions that they should only be set by the codec upon receipt of a SETTINGS ACK frame.

Modifications:
- Encoder, Decoder, and the Headers Encoder/Decoder no longer expose public constructors that allow the default settings to be changed.
- Http2HeadersDecoder#maxHeaderSize() exists to provide some bound when headers/continuation frames are being aggregated. However this is roughly the same as SETTINGS_MAX_HEADER_LIST_SIZE (besides the 32 byte octet for each header field) and can be used instead of attempting to keep the two independent values in sync.
- Encoding headers now enforces SETTINGS_MAX_HEADER_LIST_SIZE at the octect level. Previously the header encoder compared the number of header key/value pairs against SETTINGS_MAX_HEADER_LIST_SIZE instead of the number of octets (plus 32 bytes overhead).
- DefaultHttp2ConnectionDecoder#onData calls shouldIgnoreHeadersOrDataFrame but may swallow exceptions from this method. This means a STREAM_RST frame may not be sent when it should for an unknown stream and thus violate the RFC. The exception is no longer swallowed.

Result:
Default settings state is enforced and interfaces related to settings state are clarified.

4a5340eae7 Fix IndexOutOfBoundsException in HelloWorldHttp2Handler
Motivation:

We need to duplicate the buffer before passing it to writeBytes(...) as it will increase the readerIndex().

Modifications:

Call duplicate().

Result:

No more IndexOutOfBoundsException when runing the multiplex example.

e94db103c9 Ensure flowController().writePendingBytes() is triggered when writing response in example
Motivation:

We called ctx.flush() which is not correct as it will not call flowController().writePendingBytes().

Modifications:

Call flush(ChannelHandlerContext) and so also call flowController().writePendingBytes().

Result:

Correct http2 example

e3fbfe5641 HTTP/2 example upgrade refcnt bug
Motivation:
Http2ServerInitializer uses a SimpleChannelHandler in an attempt to ease putting an HttpObjectAggregator in the pipeline when no upgrade is attempted. However the message is double released because it is fired up the pipeline (which will be released) and also released by SimpleChannelHandler in a finally block.

Modifications:
- Retain the message if we fire it up the pipeline

Result:
HTTP/2 examples don't encounter a reference count error if no upgrade was attempted.

f375772ff0 Remove OSGi import of JCTools since it is shaded.
Motivation:

Since netty shaded JCTools the OSGi manifest no longer is correct. It claims to
have an optional import "org.jctools.queues;resolution:=optional,org.jctools.qu
eues.atomic;resolution:=optional,org.jctools.util;resolution:=optional"
However since it is shaded, this is no longer true.
This was noticed when making JCTools a real bundle and netty resolved it as
optional import.

Modifications:

Modify the generated manifest by no longer analyzing org.jctools for imports.
A manual setting of sun.misc as optional was required.

Result:

Netty OSGi bundle will no longer interfere with a JCTools bundle.

fa6b0e262e Support Unicode filenames and spaces in directory listing
Motivation:

The HTTP Static File Server seems to ignore filenames that doesn't contains only latin characters, but these days people wish to serve files in other languages, or even include some emojis in the filename. Although these files are not displayed on the directory listing, they are accessible by HTTP requests. This fix will make such files more visible.

Modifications:

I've changed the ALLOWED_FILE_NAME pattern to disallow only files that starts with underline, minus or a dot (such as .htaccess), and hide other "unsafe" filenames that may be used to trigger some security issues. Other filenames, including the space character are allowed.

I've also added charset encoding to the directory listing, because the browser default MAY be configured for ISO-8859-1 instead of UTF-8.

Result:

Directory listing will work for files that contains the space character, as well as other Unicode characters.

15222c084d Never expose user.dir to the web on directory listing
Motivation:

When Netty HTTP Static File Server does directory listing, it does expose the user.dir environment variable to the user. Although it doesn't a security issue, it is a bad practice to show it, and the user does expect to see the server virtual root instead, which is the absolute path as mentioned in the RFC.

Modifications:

the sendListing method receives a third argument, which is the requested URI, and this is what should be displayed on the page instead of the filesystem path.

Result:

The directory listing pages will show the virtual path as described in the URI and not the real filesystem path.

Removed fallback method

3a4d30df4e Make SocksServer example compatible with curl --socks5-hostname
Motivation:

Socks5 proxy supports resolve domain at the server side. When testing
with curl, the SocksServer in example package only works for proxy
request with IP, not with domain name (`--socks5` vs
`--socks5-hostname`). As curl is widely used, it should work with
the example provided.

Modifications:

Passing address and port to the Socks5CommandResponse, so that it
works for curl.

Result:

`curl --socks5-hostname` works as expected.

Modifications:

Remove volatile and add comment to explain why its not needed.

Result:

More correct example.

3613d15bca Split Http2MultiplexCodec into Frame- and MultiplexCodec + Tests. Fixes #4914
Motivation:

Quote from issue 4914:
"Http2MultiplexCodec currently does two things: mapping the existing h2 API to frames and managing the child channels.

It would be better if the two parts were separated. This would allow less-coupled development of the HTTP/2 handlers (flow control could be its own handler, for instance) and allow applications to insert themselves between all streams and the codec, which permits custom logic and could be used, in part, to implement custom frame types.

It would also greatly ease testing, as the child channel could be tested by itself without dealing with how frames are encoded on the wire."

Modifications:

- Split the Http2MultiplexCodec into Http2FrameCodec and Http2MultiplexCodec. The Http2FrameCodec interacts with the existing HTTP/2 callback-based API, while the Http2MulitplexCodec is completely independent of it and simply multiplexes Http2StreamFrames to the child channels. Additionally, the Http2Codec handler is introduced, which is a convenience class that simply sets up the Http2FrameCodec and Http2MultiplexCodec in the channel pipeline and removes itself.

- Improved test coverage quite a bit.

Result:

- The original Http2MultiplexCodec is split into Http2FrameCodec and Http2MultiplexCodec.
- More tests for higher confidence in the code.

3a9f472161 Make retained derived buffers recyclable
Related: #4333 #4421 #5128

Motivation:

slice(), duplicate() and readSlice() currently create a non-recyclable
derived buffer instance. Under heavy load, an application that creates a
lot of derived buffers can put the garbage collector under pressure.

Modifications:

- Add the following methods which creates a non-recyclable derived buffer
  - retainedSlice()
  - retainedDuplicate()
  - readRetainedSlice()
- Add the new recyclable derived buffer implementations, which has its
  own reference count value
- Add ByteBufHolder.retainedDuplicate()
- Add ByteBufHolder.replace(ByteBuf) so that..
  - a user can replace the content of the holder in a consistent way
  - copy/duplicate/retainedDuplicate() can delegate the holder
    construction to replace(ByteBuf)
- Use retainedDuplicate() and retainedSlice() wherever possible
- Miscellaneous:
  - Rename DuplicateByteBufTest to DuplicatedByteBufTest (missing 'D')
  - Make ReplayingDecoderByteBuf.reject() return an exception instead of
    throwing it so that its callers don't need to add dummy return
    statement

Result:

Derived buffers are now recycled when created via retainedSlice() and
retainedDuplicate() and derived from a pooled buffer

0557927b65 Updating allowNullOrigin to return 'null' instead of '*'.
Motivation:
Currently the way a 'null' origin, a request that most often indicated
that the request is coming from a file on the local file system, is
handled is incorrect. We are currently returning a wildcard origin '*'
but should be returning 'null' for the 'Access-Control-Allow-Origin'
which is valid according to the specification [1].

Modifications:
Updated CorsHandler to add a 'null' origin instead of the '*' origin in
the case the request origin is 'null.

Result:
All test pass and the CORS example as does the cors.html example if you
try to serve it by opening the file directly in a web browser.

d698746609 Add ByteBuf.asReadOnly()
Motivation:

We lately added ByteBuf.isReadOnly() which allows to detect if a buffer is read-only or not. We should add ByteBuf.asReadOnly() to allow easily access a read-only version of a buffer.

Modifications:

- Add ByteBuf.asReadOnly()
- Deprecate Unpooled.unmodifiableBuffer(Bytebuf)

Result:

More consistent api.

e053b96b5c Set the length fields of memcache messages automatically
Motivation:

People need to set all length fields manually when creating a memcache message and it's error prone. See #2736 for more dicussion.

Modifications:

This patch adds the logic to update the keyLength, extrasLength and totalBodyLength when key, extras or content is set.

Result:

The length fields of memcache messages will be updated automatically.

e24a5d8839 Map HTTP/2 Streams to Channels
Motivation:

This allows using handlers for Streams in normal Netty-style. Frames are
read/written to the channel as messages, not directly as a
callback/method call. Handlers allow mixing and can ease HTTP/1 and
HTTP/2 interoperability by eventually supporting HTTP/1 handlers in
HTTP/2 and vise versa.

Modifications:

New handler Http2MultiplexCodec that converts from the current HTTP/2
API to a message-based API and child channels for streams.

Result:

The basics are done for server-side: new streams trigger creation of new
channels in much the same appearance to how new connections trigger new
channel creation. The basic frames HEADERS and DATA are handled, but
also GOAWAY and RST_STREAM.

Inbound flow control is implemented, but outbound is not. That will be
done later, along with not completing write promises on the child
channel until the write actually completes on the parent.

There is not yet support for outbound priority/weight, push promises,
and many other features.

There is a generic Object that may be set on stream frames. This also
paves the way for client-side support which needs a way to refer to
yet-to-be-created streams (due to how HEADERS allocates a stream id, and
the allocation order must be the same as transmission order).

68bbd4e966 Handle only those http requests that equal to adjusted websocket path
Motivation:

It will be easier to support websockets in server application by using WebSocketServerProtocolHandshakeHandler class and not reinvent its functionality. But currently it handles all http requests as if they were websocket handshake requests.

Modifications:

Check if http request path is equals to adjusted websocket path.
Fixed example of websocket server implementation.

Result:

WebSocketServerProtocolHandshakeHandler handles only websocket handshake requests.

36aa11937d ByteBuf for Key instead of String for codec-memcache
Motivation:

The key can be ByteBuf to avoid converting between ByteBuf and String. See #3689.

Modifications:

210ebe1354 Allow to specify tcnative artifactId and verion to allow run tests easily with different tcnative flavors
Motivation:

As we now can easily build static linked versions of tcnative it makes sense to run our netty build against all of them.
This helps to ensure our code works with libressl, openssl and boringssl.

Modifications:

Allow to specify -Dtcnative.artifactId= and -Dtcnative.version=

Result:

Easy to run netty build against different tcnative flavors.
