174f4ea005 HttpServerKeepAliveHandler doesn't correctly handle VoidChannelPromise
Motivation:

HttpServerKeepAliveHandler throws unexpected error when I do ctx.writeAndFlush(msg, ctx.voidPromise()); where msg is with header "Connection:close".

Modification:

HttpServerKeepAliveHandler does promise.unvoid() before adding close listener.

Result:

No error for VoidChannelPromise with HttpServerKeepAliveHandler. Fixes [#6698].

464ae9fb7a Expose CharSequence version of HttpUtil#getMimeType and HttpUtil#getCharset
Motivation:

It would be more flexible to make getCharset and getMimeType code usable not only for HttpMessage entity but just for any CharSequence. This will improve usability in general purpose code and will help to avoid multiple fetching of ContentType header from a message. It could be done in an external code once and CharSequence method versions could be applied.

Modification:
Expose HttpUtil#getMimeType, HttpUtil#getCharsetAsString, HttpUtil#getCharset versions which works with CharSequence. New methods are reused in the old ones which work with HttpMessage entity.

Result:

More flexible methods set with a good code reusing.

e70fbe316d Fire exceptionCaught before exception-caused close for WebSockets.
Motivation:

WebSocket decoding throws exceptions on failure that should cause the
pipline to close.  These are currently ignored in the
`WebSocketProtocolHandler` and `WebSocketServerProtocolHandler`.  In
particular, this means that messages exceding the max message size will
cause the channel to close with no reported failure.

Modifications:

Re-fire the event just before closing the socket to allow it to be
handled appropriately.

Result:

Closes [#3063].

b1cb059540 Motivation:
It is generally useful to have origin http servers respond to
"expect: continue-100" as soon as possible but applications without a
HttpObjectAggregator in their pipelines must use boiler plate to do so.

Modifications:

Introduce the HttpServerExpectContinueHandler handler to make it easier.

Result:

Less boiler plate for http application authors.

ffd6911586 Use constant string instead of user provided file name for DiskFileUpload temp file names.
Motivation:

DiskFileUpload creates temporary files for storing user uploads containing the user provided file name as part of the temporary file name. While most security problems are prevented by using "new File(userFileName).getName()" a small risk for bugs or security issues remains.

Modifications:

Use a constant string as file name and rely on the callers use of File.createTemp to ensure unique disk file names.

Result:

A slight security improvement at the cost of a little more obfuscated temp file names.

b041f1a7a9 HttpServerKeepAliveHandler 204 response with no Content-Length should keepalive
Motivation:
https://tools.ietf.org/html/rfc7230#section-3.3.2 states that a 204 response MUST NOT include a Content-Length header. If the HTTP version permits keep alive these responses should be treated as keeping the connection alive even if there is no Content-Length header.

Modifications:
- HttpServerKeepAliveHandler#isSelfDefinedMessageLength should account for 204 respones

Result:
Fixes https://github.com/netty/netty/issues/6549.

71b338ce17 Non-latin character broken on HttpHeader by HttpObjectDecoder.
Motivation:

Currently netty is receiving HTTP request by ByteBuf and store it as "CharSequence" on HttpObjectDecoder. During this operation, all character on ByteBuf is moving to char[] without breaking encoding.
But in process() function, type casting from byte to char does not consider msb (sign-bit). So the value over 127 can be casted wrong value. (ex : 0xec in byte -> 0xffec in char). This is type casting bug.

Modification:

Fix type casting

Result:

Non-latin characters work.

9c1a191696 Trim optional white space in CombinedHttpHeaders values
Motivation:

The updated HTTP/1.x RFC allows for header values to be CSV and separated by OWS [1]. CombinedHttpHeaders should remove this OWS on insertion.

[1] https://tools.ietf.org/html/rfc7230#section-7

Modification:

CombinedHttpHeaders doesn't account for the OWS and returns it back to the user as part of the value.

d1b0225724 Improvement : WebSocketServerProtocolHandshakeHandler.getWebSocketLocation now applies concat optimization and WebSocket path check moved to separated method.
Motivation:

Make code easier to read, make WebSocketServerProtocolHandshakeHandler.getWebSocketLocation method faster.

Modification:

WebSocket path check moved to separate method. Get header operation moved out from concat operation.

Result:

WebSocketServerProtocolHandshakeHandler.getWebSocketLocation is faster as OptimizeStringConcat could be applied. Code easier to read.

c92565d5c7 Correct expect header handling
Motivation:

Today, the HTTP codec in Netty responds to HTTP/1.1 requests containing
an "expect: 100-continue" header and a content-length that exceeds the
max content length for the server with a 417 status (Expectation
Failed). This is a violation of the HTTP specification. The purpose of
this commit is to address this situation by modifying the HTTP codec to
respond in this situation with a 413 status (Request Entity Too
Large). Additionally, the HTTP codec ignores expectations in the expect
header that are currently unsupported. This commit also addresses this
situation by responding with a 417 status.

Handling the expect header is tricky business as the specification (RFC
2616) is more complicated than it needs to be. The specification defines
the legitimate values for this header as "100-continue" and defines the
notion of expectatation extensions. Further, the specification defines a
417 status (Expectation Failed) and this is where implementations go
astray. The intent of the specification was for servers to respond with
417 status when they do not support the expectation in the expect
header.

The key sentence from the specification follows:

    The server MUST respond with a 417 (Expectation Failed) status if
    any of the expectations cannot be met or, if there are other
    problems with the request, some other 4xx status.

That is, a server should respond with a 417 status if and only if there
is an expectation that the server does not support (whether it be
100-continue, or another expectation extension), and should respond with
another 4xx status code if the expectation is supported but there is
something else wrong with the request.

Modifications:

This commit modifies the HTTP codec by changing the handling for the
expect header in the HTTP object aggregator. In particular, the codec
will now respond with 417 status if any expectation other than
100-continue is present in the expect header, the codec will respond
with 413 status if the 100-continue expectation is present in the expect
header and the content-length is larger than the max content length for
the aggregator, and otherwise the codec will respond with 100 status.

Result:

The HTTP codec can now be used to correctly reply to clients that send a
100-continue expectation with a content-length that is too large for the
server with a 413 status, and servers that use the HTTP codec will now
no longer ignore expectations that are not supported (any value other
than 100-continue).

64abef5f5b Add exposeHeaders and allowedRequestHeaders that accept CharSequence, close #6328
Motivation:

Netty 4.1 introduced AsciiString and defines HttpHeaderNames constants
as such.

It would be convenient to be able to pass them to `exposeHeaders` and
`allowedRequestHeaders` directly without having to call `toString`.

Modifications:

Add `exposeHeaders` and `allowedRequestHeaders` overloads that take a
`CharSequence`.

Result:

More convenient API

9d45f514a4 Add a constant for Cookie "undefined maxAge"
Motivation:

DefaultCookie currently used an undocumented magic value for undefined
maxAge.

Clients need to be able to identify such value so they can implement a
proper CookieJar.

Ideally, we should add a `Cookie::isMaxAgeDefined` method but I guess
we can’t add a new method without breaking API :(

Modifications:

Add a new constant on `Cookie` interface so clients can use it to
compare with value return by `Cookie.maxAge` and decide if `maxAge` was
actually defined.

Result:

Clients have a better documented way to check if the maxAge attribute
was defined.

0f9b739508 AggregatedFullHttpMessage.replace should also copy a decoder result
Motivation:

HttpObjectAggregator yields full HTTP messgaes (AggregatedFullHttpMessages) that don't respect decoder result when copied/replaced.

Modifications:

Copy the decoding result over to a new instance produced by AggregatedFullHttpRequest.replace or AggregatedFullHttpResponse.replace .

Result:

DecoderResult is now copied over when an original AggregatedFullHttpMessage is being replaced (i.e., AggregatedFullHttpRequest.replace or AggregatedFullHttpResponse.replace is being called).

New unit tests are passing on this branch but are failing on master.

9bec25a6eb Set the Transfer-Encoding header instead of adding
Motivation:

HttpUtil.setTransferEncodingChunked could add a second Transfer-Encoding
header if one was already present. While this is technically valid, it
does not appear to be the intent of the method.

Result:

Only one Transfer-Encoding header is present after calling this method.

56ddc47f23 Extends HttpPostRequestEncoder to support all methods except TRACE
Motivation:

In Netty, currently, the HttpPostRequestEncoder only supports POST, PUT, PATCH and OPTIONS, while the RFC 7231 allows with a warning that GET, HEAD, DELETE and CONNECT use a body too (but not TRACE where it is explicitely not allowed).
The RFC in chapter 4.3 says:
"A payload within a XXX request message has no defined semantics;
sending a payload body on a XXX request might cause some existing
implementations to reject the request."
where XXX can be replaced by one of GET, HEAD, DELETE or CONNECT.

Current usages, on particular in REST mode, tend to use those extra HttpMethods for such queries.

So this PR proposes to remove the current restrictions, leaving only TRACE as explicitely not supported.

Modification:

In the constructor, where the test is done, replacing all by checking only against TRACE, and adding one test to check that all methods are supported or not.

Result:

Fixes #6138.

16ddf460a6 Added checkStartsWith option for WebSocketServerProtocolHandler
Motivation:

Enables optional .startsWith() matching of req.uri() with websocketPath.

Modifications:

New checkStartsWith boolean option with default false value added to both WebSocketServerProtocolHandler and WebSocketServerProtocolHandshakeHandler. req.uri() matching is based on this option.

Result:

By default old behavior matching via .equal() is preserved. To use checkStartsWith use constructor shortcut: new WebSocketServerProtocolHandler(websocketPath, true) or fill this flag on full form of constructor among other options.

cb139043f3 [#5831] HttpServerCodec cannot encode a respons e to HEAD
request with a 'content-encoding: chunked' header

Motivation:

It is valid to send a response to a HEAD request that contains a transfer-encoding: chunked header, but it is not valid to include a body, and there is no way to do this using the netty4 HttpServerCodec.

The root cause is that the netty4 HttpObjectEncoder will transition to the state ST_CONTENT_CHUNK and the only way to transition back to ST_INIT is through the encodeChunkedContent method which will write the terminating length (0\r\n\r\n\r\n), a protocol error when responding to a HEAD request

Modifications:

- Keep track of the method of the request and depending on it handle the response differently when encoding it.
- Added a unit test.

Result:

Correclty handle HEAD responses that are chunked.

ea0ddc0ea2 fix #6066 Support optional filename in HttpPostRequestEncoder
Motivation:

According to https://www.ietf.org/rfc/rfc2388.txt 4.4, filename after "content-disposition" is optional and arbitrary (does not need to match a real filename).

Modifications:

This change supports an extra addBodyFileUpload overload to precise the filename (default to File.getName). If empty or null this argument should be ignored during encoding.

Result:
- A backward-compatible addBodyFileUpload(String, File, String, boolean) to use file.getName() as filename.
- A new addBodyFileUpload(String, String, File, String, boolean) overload to precise filename
- Couple of tests for the empty use case

ba95c401a7 Misc clean up
Motivation:
IntelliJ issues several warnings.

Modifications:

* `ClientCookieDecoder` and `ServerCookieDecoder`:
  * `nameEnd`, `valueBegin` and `valueEnd` don't need to be initialized
  * `keyValLoop` loop doesn't been to be labelled, as it's the most inner one (same thing for labelled breaks)
  * Remove `if (i != headerLen)` as condition is always true
* `ClientCookieEncoder` javadoc still mention old logic
* `DefaultCookie`, `ServerCookieEncoder` and `DefaultHttpHeaders` use ternary ops that can be turned into simple boolean ones
* `DefaultHeaders` uses a for(int) loop over an array. It can be turned into a foreach one as javac doesn't allocate an iterator to iterate over arrays
* `DefaultHttp2Headers` and `AbstractByteBuf` `equal` can be turned into a single boolean statement

explicitly check for number of digits between separators instead of relying on the numeric value.
also add tests.

edc4842309 Fix cookie date parsing, close #6016
Motivation:
* RFC6265 defines its own parser which is different from RFC1123 (it accepts RFC1123 format but also other ones). Basically, it's very lax on delimiters, ignores day of week and timezone. Currently, ClientCookieDecoder uses HttpHeaderDateFormat underneath, and can't parse valid cookies such as Github ones whose expires attribute looks like "Sun, 27 Nov 2016 19:37:15 -0000"
* ServerSideCookieEncoder currently uses HttpHeaderDateFormat underneath for formatting expires field, and it's slow.

Modifications:
* Introduce HttpHeaderDateFormatter that correctly implement RFC6265
* Use HttpHeaderDateFormatter in ClientCookieDecoder and ServerCookieEncoder
* Deprecate HttpHeaderDateFormat

Result:
* Proper RFC6265 dates support
* Faster ServerCookieEncoder and ClientCookieDecoder
* Faster tool for handling headers such as "Expires" and "Date"

0bc30a123e Eliminate usage of releaseLater(...) to reduce memory usage during tests
Motiviation:

We used ReferenceCountUtil.releaseLater(...) in our tests which simplifies a bit the releasing of ReferenceCounted objects. The problem with this is that while it simplifies stuff it increase memory usage a lot as memory may not be freed up in a timely manner.

Modifications:

- Deprecate releaseLater(...)
- Remove usage of releaseLater(...) in tests.

Result:

Less memory needed to build netty while running the tests.

Result:

If a remote server doesn't know how to use the http upgrade and tries to
responsd with a streaming response that never ends, the client doesn't
buffer forever, but can instead pass it along.  Fixes #5954

cf8f6e3e2f [#5861] HttpUtil.getContentLength(HttpMessage, long) throws unexpected NumberFormatException
Motivation:

The Javadocs of HttpUtil.getContentLength(HttpMessage, long) and its int overload state that the provided default value is returned if the Content-Length value is not a number. NumberFormatException is thrown instead.

Modifications:

Correctly handle when the value is not a number.

Result:

API works as stated in javadocs.

dd1ba2a252 HttpObjectDecoder resetRequested not updated after reset
Motivation:
HttpObjectDecoder maintains a resetRequested flag which is used to determine if internal state should be reset when a decode occurs. However after a reset is done the resetRequested flag is not set to false. This leads to all data after this point being discarded.

Modifications:
- Set resetRequested to false when a reset is done

Result:
HttpObjectDecoder can still function after a reset.

c57d4bed91 Add HttpServerKeepAliveHandler
Motivation:

As discussed in #5738, developers need to concern themselves with setting
connection: keep-alive on the response as well as whether to close a
connection or not after writing a response.  This leads to special keep-alive
handling logic in many different places.  The purpose of the HttpServerKeepAliveHandler
is to allow developers to add this handler to their pipeline and therefore
free themselves of having to worry about the details of how Keep-Alive works.

Modifications:

Added HttpServerKeepAliveHandler to the io.netty.handler.codec.http package.

Result:

Developers can start using HttpServerKeepAliveHandler in their pipeline instead
of worrying about when to close a connection for keep-alive.

245fb52c90 Provide extra info together with handshake complete event.
Motivation:

As described in #5734

Before this change, if the server had to do some sort of setup after a
handshake was completed based on handshake's information, the only way
available was to wait (in a separate thread) for the handshaker to be
added as an attribute to the channel. Too much hassle.

Modifications:

Handshake completed event need to be stateful now, so I've added a tiny
class holding just the HTTP upgrade request and the selected subprotocol
which is fired as an event after the handshake has finished.
I've also deprecated the old enum used as stateless event and I left the
code that fires it for backward compatibility. It should be removed in
the next mayor release.

Result:

It should be much simpler now to do initialization stuff based on
subprotocol or request headers on handshake completion. No asynchronous
waiting needed anymore.

e3aca1f3d6 CorsHandler to respect http connection (keep-alive) header.
Motivation:

The CorsHandler currently closes the channel when it responds to a preflight (OPTIONS)
request or in the event of a short circuit due to failed validation.

Especially in an environment where there's a proxy in front of the service this causes
unnecessary connection churn.

Modifications:

CorsHandler now uses HttpUtil to determine if the connection should be closed
after responding and to set the Connection header on the response.

Result:

Channel will stay open when the CorsHandler responds unless the client specifies otherwise
or the protocol version is HTTP/1.0

f6c16f4897 Attempt at improving docs in HttpObjectAggregator
Motivation:

Documentation was added in #2401 to aid developers in understanding
how HttpObjectAggregator works and that it needs an encoder before it.

In #2471 it was pointed out that the documentation added can actually
add to the confusion and that it might have a typo.

This is an attempt at clearing up that confusion.  Feedback is welcome.

Modifications:

- Adjust class level javadoc for HttpObjectAggregator
  * Remove reference to HttpRequestEncoder
  * Point out when HttpResponseEncoder is needed
  * Point out that either HttpRequestDecoder or HttpResponseDecoder is needed
  * Make clear everything must be added before HttpObjectAggregator
  * Mention HttpServerCodec

Result:

Avoid confusion about dependencies for HttpObjectAggregator on the pipeline.

8d043cc4dd Do not return Access-Control-Allow-Headers on Non-Preflight Cors requests
Motivation:

The CorsHandler currently returns the Access-Control-Allow-Headers
header as on a Non-Preflight CORS request (Simple request).
As per the CORS specification the Access-Control-Allow-Headers header
should only be returned on Preflight requests. (not on simple requests).

https://www.w3.org/TR/2014/REC-cors-20140116/#access-control-allow-headers-response-header

http://www.html5rocks.com/static/images/cors_server_flowchart.png

Modifications:

Modified CorsHandler.java to not add the Access-Control-Allow-Headers
header when responding to Non-preflight CORS request.

Result:

Access-Control-Allow-Headers header will not be returned on a Simple
request (Non-preflight CORS request).

82b617dfe9 retainSlice() unwrap ByteBuf
Motivation:
retainSlice() currently does not unwrap the ByteBuf when creating the ByteBuf wrapper. This effectivley forms a linked list of ByteBuf when it is only necessary to maintain a reference to the unwrapped ByteBuf.

Modifications:
- retainSlice() and retainDuplicate() variants should only maintain a reference to the unwrapped ByteBuf
- create new unit tests which generally verify the retainSlice() behavior
- Remove unecessary generic arguments from AbstractPooledDerivedByteBuf
- Remove unecessary int length member variable from the unpooled sliced ByteBuf implementation
- Rename the unpooled sliced/derived ByteBuf to include Unpooled in their name to be more consistent with the Pooled variants

Result:

e845670043 Set some StackTraceElement on pre-instantiated static exceptions
Motivation:

We use pre-instantiated exceptions in various places for performance reasons. These exceptions don't include a stacktrace which makes it hard to know where the exception was thrown. This is especially true as we use the same exception type (for example ChannelClosedException) in different places. Setting some StackTraceElements will provide more context as to where these exceptions original and make debugging easier.

Modifications:

Set a generated StackTraceElement on these pre-instantiated exceptions which at least contains the origin class and method name. The filename and linenumber are specified as unkown (as stated in the javadocs of StackTraceElement).

Result:

Easier to find the origin of a pre-instantiated exception.

4a1e0ceb4d [5382] HttpContentEncoder should not set chunked transfer-encoding for HTTP/1.0
Motivation:

When using HttpContentCompressor and the HttpResponse is protocol version 1.0, HttpContentEncoder.encode() should not set the transfer-encoding header to chunked. Chunked transfer-encoding is not valid for HTTP 1.0 - this causes ERR_CONTENT_DECODING_FAILED errors in chrome and similar failures in IE.

Modifications:

Skip HTTP/1.0 messages

Result:

Be able to serve HTTP/1.0 as well when HttpContentEncoder is in the pipeline.

Modifications:

If readChunk(...) return null just return null as well.

Result:

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

Motivation:

When the channel is closed while we still decode the headers we currently not preserve correct message sequence. In this case we should generate an invalid message with a current cause.

Modifications:

1cb706ac93 HTTP/2 HPACK Header Name Validation and Trailing Padding
Motivation:
The HPACK code currently disallows empty header names. This is not explicitly forbidden by the HPACK RFC https://tools.ietf.org/html/rfc7541. However the HTTP/1.x RFC https://tools.ietf.org/html/rfc7230#section-3.2 and thus HTTP/2 both disallow empty header names, and so this precondition check should be moved from the HPACK code to the protocol level.
HPACK also requires that string literals which are huffman encoded must be treated as an encoding error if the string has more than 7 trailing padding bits https://tools.ietf.org/html/rfc7541#section-5.2, but this is currently not enforced.

Result:
- HPACK to allow empty header names
- HTTP/1.x and HTTP/2 header validation should not allow empty header names
- Enforce max of 7 trailing padding bits

Result:
Code is more compliant with the above mentioned RFCs

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.

24254b159f Propagate h2c upgrade success event to the next handler before removing source codec
Motivation:

When upgrading h2c, I found that sometimes both of http2 settings frame and http response message was arrived before receiving upgrade success event. It was because ByteToMessageDecoder propagated its internally buffered message to the next handler when removing itself from pipeline.(refer to ByteToMessageDecoder#handlerRemoved)
I think it's better to propagate upgrade success event when handling 101 switching protocol response.

Modifications:

Upgrade success event will be propagated before removing source codec.

Result:

It guarantees that upgrade success event will be arrived first at the next handler.

881ff3cd98 Drop broken DefaultCookie name validation, close #4999
Motivation:

DefaultCookie constructor performs a name validation that doesn’t match
RFC6265. Moreover, such validation is already performed in strict
encoders and decoders.

Modifications:

Drop DefaultCookie name validation, rely on encoders and decoders.

Result:

no more duplicate broken validation

8ec594c6eb Change HttpServerUpgradeHandler.UpgradeCodec to allow aborting upgrade
Motivation:

HttpServerUpgradeHandler.UpgradeCodec.prepareUpgradeResponse should allow to abort the upgrade and so just continue with using HTTP. Beside this we should only pass in the response HttpHeaders as this is inline with the docs.

Modifications:

- UpgradeCodec.prepareUpgradeResponse now allows to return a boolean and so allows to specifiy if the upgrade should take place.
- Change the param from FullHttpResponse to HttpHeaders to be inline with the javadocs.

Result:

More flexible and correct handling of upgrades.

ed9d6c79bc [#4972] Remove misleading argument from HttpServerUpgradeHandler.UpgradeCodec.upgradeTo
Motivation:

upgradeTo(...) takes the response as paramater, but the respone itself was already written to the Channel. This gives the user the impression the response can be changed or even act on it which may not be safe anymore once it was written and has been released.

Modifications:

Remove the response param from the method.

Result:

Less confusion and safer usage.

3d7cec6376 Bug fix for HttpPostMultipartRequestDecoder part decoding with an invalid charset not reported as an ErrorDataDecoderException
Motivation:

The current HttpPostMultipartRequestDecoder can decode multipart/form-data parts with a Content-Type that specifies a charset. When this charset is invalid the Charset.forName() throws an unchecked UnsupportedCharsetException. This exception is not catched by the decoder. It should actually be rethrown as an ErrorDataDecoderException, because the developer using the API would expect this validation failure to be reported as such.

Modifications:

Add a catch block for UnsupportedCharsetException and rethrow it as an ErrorDataDecoderException.

Result:

UnsupportedCharsetException are now rethrown as ErrorDataDecoderException.

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.

Result:
The ByteBuf assigned to the FullHttpMessage can now be configured as a pooled/unpooled, direct/heap based ByteBuf via the ByteBufAllocator used.

333f55e9ce Add unescapeCsvFields to parse a CSV line and implement CombinedHttpHeaders.getAll
Motivation:

See #4855

Modifications:

Unfortunately, unescapeCsv cannot be used here because the input could be a CSV line like `"a,b",c`. Hence this patch adds unescapeCsvFields to parse a CSV line and split it into multiple fields and unescaped them. The unit tests should define the behavior of unescapeCsvFields.

Then this patch just uses unescapeCsvFields to implement `CombinedHttpHeaders.getAll`.

Result:

`CombinedHttpHeaders.getAll` will return the unescaped values of a header.

b112673554 ByteToMessageDecoder ChannelInputShutdownEvent support
Motivation:
b714297a44 introduced ChannelInputShutdownEvent support for HttpObjectDecoder. However this should have been added to the super class ByteToMessageDecoder, and ByteToMessageDecoder should not propegate a channelInactive event through the pipeline in this case.

Modifications:
- Move the ChannelInputShutdownEvent handling from HttpObjectDecoder to ByteToMessageDecoder
- ByteToMessageDecoder doesn't call ctx.fireChannelInactive() on ChannelInputShutdownEvent

Result:
Half closed events are treated more generically, and don't get translated into a channelInactive pipeline event.

a15ff32608 HttpObjectDecoder configurable initial buffer size
Motivation:
The initial buffer size used to decode HTTP objects is currently fixed at 128. This may be too small for some use cases and create a high amount of overhead associated with resizing/copying. The user should be able to configure the initial size as they please.

Modifications:
- Make HttpObjectDecoder's AppendableCharSequence initial size configurable

Result:
Users can more finely tune initial buffer size for increased performance or to save memory.

Motivation:

If the Connection header contains multiple values (which is valid) we fail to detect a websocket upgrade

Modification:

- Add new method which allows to check if a header field contains a specific value (and also respect multiple header values)
- Use this method to detect handshake

Result:

Correct detect handshake if Connection header contains multiple values (seperated by ',').

Modifications:

Result:

Support window size flag by default in most installations.

7a562943ad [#4533] Ensure replacement of decoder is delayed after finishHandshake() is called
Motivation:

If the user calls handshake.finishHandshake() we need to ensure that the user has the chance to setup the pipeline before any WebSocketFrames are read. Because of this we need
to delay the removal of the HttpRequestDecoder.

Modifications:

- Remove the HttpRequestDecoder via the EventLoop and so delay it which gives the user a chance to setup the pipeline after finishHandshake() completes
- Add unit test for this.

Result:

Less surpising and correct behaviour even if the http response and websocket frame are received in one read operation.

d97f17060f Support non chunked HTTP request bodies larger than Integer.MAX_VALUE.
Motivation:

Request bodies can easily be larger than Integer.MAX_VALUE in practice.
There's no reason, or intention, for Netty to impose this artificial constraint.

Worse, it currently does not fail if the body is larger than this value;
it just silently only reads the first Integer.MAX_VALUE bytes and discards the rest.

This restriction doesn't effect chunked transfers, with no Content-Length header.

Modifications:

Force the use of `long HttpUtil.getContentLength(HttpMessage, long)` instead of
`long HttpUtil.getContentLength(HttpMessage, long)`.

Result:

Netty will support HTTP request bodies of up to Long.MAX_VALUE length.

4d6ab1d30d Fix missing trailing data on HTTP client upgrade
Motivation:

When HttpClientUpgradeHandler upgrades from HTTP/1 to another protocol,
it performs a two-step opertion:

1. Remove the SourceCodec (HttpClientCodec)
2. Add the UpgradeCodec

When HttpClientCodec is removed from the pipeline, the decoder being
removed triggers channelRead() event with the data left in its
cumulation buffer. However, this is not received by the UpgradeCodec
becuase it's not added yet. e.g. HTTP/2 SETTINGS frame sent by the
server can be missed out.

To fix the problem, we need to reverse the steps:

1. Add the UpgradeCodec
2. Remove the SourceCodec

However, this does not work as expected either, because UpgradeCodec can
send a greeting message such as HTTP/2 Preface. Such a greeting message
will be handled by the SourceCodec and will trigger an 'unsupported
message type' exception.

To fix the problem really, we need to make the upgrade process 3-step:

1. Remove/disable the encoder of SourceCodec
2. Add the UpgradeCodec
3. Remove the SourceCodec

Modifications:

- Add SourceCodec.prepareUpgradeFrom() so that SourceCodec can remove or
  disable its encoder
- Implement HttpClientCodec.prepareUpgradeFrom() properly
- Miscellaneous:
  - Log the related channel as well When logging the failure to send a
    GOAWAY

Result:

Cleartext HTTP/1-to-HTTP/2 upgrade works again.

c1f3200c87 Fix the incorrect usage/value of 'Connection: upgrade'
Motivation:

HttpClientUpgradeHandler uses HttpHeaderNames.UPGRADE as the value of
the 'Connection' header, which is incorrect. It should use
HttpHeaderValues.UPGRADE instead (note Names vs Values.)

Also, HttpHeaderValues.UPGRADE should be 'upgrade' rather than
'Upgrade', as defined in:

- https://tools.ietf.org/html/rfc7230#section-6.7

Modifications:

- Use HttpHeaderValues.UPGRADE for a 'Connection' header
- Lowercase the value of HttpHeaderValues.UPGRADE

9dd68d0c3e Fix IllegalReferenceCountException caused by HttpClientCodec.upgradeFrom()
Motivation:

On a successful protocol upgrade in HTTP, HttpClientUpgradeHandler calls
HttpClientCodec.upgradeFrom(), which removed both the HTTP encoder and
decoder from the pipeline immediately.

However, because the decoder is in the middle of the decode loop,
removing it from the pipeline immediately will cause the cumulation
buffer to be released prematurely.

This often leads to an IllegalReferenceCountException or missing first
response after the upgrade response.

Modifications:

- Remove the decoder *after* the decode loop is done

Result:

Fixes #4504

ef3a9b0acd Relax the sanity check in HttpClientUpgradeHandler
Motivation:

HttpClientUpgradeHandler currently throws an IllegalStateException when
the server sends a '101 Switching Protocols' response that has no
'Upgrade' header.

Some servers do not send the 'Upgrade' header on a successful protocol
upgrade and we could safely assume that the server accepted the
requested protocol upgrade in such a case, looking from the response
status code (101)

Modifications:

- Do not throw an IllegalStateException when the server responded 101
  without a 'Upgrade' header
- Note that we still check the equality of the 'Upgrade' header when it
  is present.

Result:

- Fixes #4523
- Better interoperability

4978266d52 Make cookie encoding conform better to RFC 6265 in STRICT mode.
Motivation:

- On the client, cookies should be sorted in decreasing order of path
  length. From RFC 6265:

      5.4.2. The user agent SHOULD sort the cookie-list in the following
      order:

        *  Cookies with longer paths are listed before cookies with
           shorter paths.

        *  Among cookies that have equal-length path fields, cookies with
           earlier creation-times are listed before cookies with later
           creation-times.

      NOTE: Not all user agents sort the cookie-list in this order, but
      this order reflects common practice when this document was
      written, and, historically, there have been servers that
      (erroneously) depended on this order.

  Note that the RFC does not define the path length of cookies without a
  path. We sort pathless cookies before cookies with the longest path,
  since pathless cookies inherit the request path (and setting a path
  that is longer than the request path is of limited use, since it cannot
  be read from the context in which it is written).

- On the server, if there are multiple cookies of the same name, only one
  of them should be encoded. RFC 6265 says:

      Servers SHOULD NOT include more than one Set-Cookie header field in
      the same response with the same cookie-name.

  Note that the RFC does not define which cookie should be set in the case
  of multiple cookies with the same name; we arbitrarily pick the last one.

Modifications:

- Changed the visibility of the 'strict' field to 'protected' in
  CookieEncoder.

- Modified ClientCookieEncoder to sort cookies in decreasing order of path
  length when in strict mode.

- Modified ServerCookieEncoder to return only the last cookie of a given
  name when in strict mode.

- Added a fast path for both strict mode in both client and server code
  for cases with only one cookie, in order avoid the overhead of sorting
  and memory allocation.

- Added unit tests for the new cases.

Result:

- Cookie generation on client and server is now more conformant to RFC 6265.

2a65ae256e [#4331] Helper methods to get charset from Content-Type header of HttpMessage
Motivation:

HttpHeaders already has specific methods for such popular and simple headers like "Host", but if I need to convert POST raw body to string I need to parse complex ContentType header in my code.

Modifications:

Add getCharset and getCharsetAsString methods to parse charset from Content-Length header.

Result:

Easy to use utility method.

0d71744d5b IllegalRefCountException in FullHttp[Request|Response].hashCode()
Motivation:
FullHttp[Request|Response].hashCode() uses a releasable object and in vulnerable to a IllegalRefCountException if that object has been released.

Modifications:
- Ensure the released object is not used.

Result:
No more IllegalRefCountException.

6e108cb96a Improve the performance of copying header sets when hashing and name validation are equivalent.
Motivation:
Headers and groups of headers are frequently copied and the current mechanism is slower than it needs to be.

Modifications:
Skip name validation and hash computation when they are not necessary.
Fix emergent bug in CombinedHttpHeaders identified with better testing
Fix memory leak in DefaultHttp2Headers when clearing
Added benchmarks

Result:
Faster header copying and some collateral bug fixes

3eb65797ed Make headers.set(self) a no-op instead of throwing. Makes it consistent with setAll
Motivation:

Makes the API contract of headers more consistent and simpler.

Modifications:

If self is passed to set then simply return

Result:

set and setAll will be consistent

19658e9cd8 HTTP/2 Headers Type Updates
Motivation:
The HTTP/2 RFC (https://tools.ietf.org/html/rfc7540#section-8.1.2) indicates that header names consist of ASCII characters. We currently use ByteString to represent HTTP/2 header names. The HTTP/2 RFC (https://tools.ietf.org/html/rfc7540#section-10.3) also eludes to header values inheriting the same validity characteristics as HTTP/1.x. Using AsciiString for the value type of HTTP/2 headers would allow for re-use of predefined HTTP/1.x values, and make comparisons more intuitive. The Headers<T> interface could also be expanded to allow for easier use of header types which do not have the same Key and Value type.

Motivation:
- Change Headers<T> to Headers<K, V>
- Change Http2Headers<ByteString> to Http2Headers<CharSequence, CharSequence>
- Remove ByteString. Having AsciiString extend ByteString complicates equality comparisons when the hash code algorithm is no longer shared.

Result:
Http2Header types are more representative of the HTTP/2 RFC, and relationship between HTTP/2 header name/values more directly relates to HTTP/1.x header names/values.

e121c68e0f Created RTSPEncoder and RTSPDecoder which are now common for both requests and responses to be able to handle both types of messages on the same channel.
Keep RTSPRequestEncoder, RTSPRequestDecoder, RTSPResponseEncoder and
RTSPResponseDecoder for backwards compatibility but they now just extends
the generic encoder/decoder and are markes as deprecated.

Renamed the decoder test, because the decoder is now generic. Added
testcase for when ANNOUNCE request is received from server.

Created testcases for encoder.

Mark abstract base classes RTSPObjectEncoder and RTSPObjectDecoder as
deprecated, that functionality is now in RTSPEncoder and RTSPDecoder.

Added annotation in RtspHeaders to suppress warnings about deprecation, no need when
whole class is deprecated.

0555b0aefd HTTP Headers Over Deprecation
Motivation:
As part of recent efforts to rectify performance and make 4.1 headers more similar to 5.0 some methods were deprecated. Some of these methods were deprecated because they used String instead of CharSequence in the signature, which may require casting at the user level. Some of the deprecated methods have no direct alternatives and were done to inform a user the method will go away in future releases.

Modifications:
- Remove the deprecated qualifier from methods where no direct replacement exists

Result:
Less warnings in user code.

99b11c95b4 [#4327] Ensure toString() will not throw IllegalReferenceCountException
Motivation:

As toString() is often used while logging we need to ensure this produces no exception.

Modifications:

Ensure we never throw an IllegalReferenceCountException.

Result:

Be able to log without produce exceptions.

ca44436ce6 [#4265] Not allow to add/set DefaultHttpHeaders to itself.
Motivation:

We should prevent to add/set DefaultHttpHeaders to itself to prevent unexpected side-effects.

Modifications:

Throw IllegalArgumentException if user tries to pass the same instance to set/add.

Result:

No surprising side-effects.

c7e3f6c6fd HTTP/2 defines using String instead of CharSequence
Motivation:
Http2CodecUtils has some static variables which are defined as Strings instead of CharSequence. One of these defines is used as a header name and should be AsciiString.

Modifications:
- Change the String defines in Http2CodecUtils to CharSequence

Result:
Types are more consistently using CharSequence and adding the upgrade header will require less work.

2a4276e1ff SpdyHttpHeaders are not lowercase
Motivation:
According to the SPDY spec https://www.chromium.org/spdy/spdy-protocol/spdy-protocol-draft3-1#TOC-3.2.1-Request header names must be lowercase. Our predefined SPDY extension headers are not lowercase.

Modifications
- SpdyHttpHeaders should define header names in lower case

Result:
Compliant with SPDY spec, and header validation code does not detect errors for our own header names.

59600f1812 HTTP/2 to HTTP/1.x headers conversion more accessible
Motivation:
Currently there is a HttpConversionUtil.addHttp2ToHttpHeaders which requires a FullHttpMessage, but this may not always be available. There is no interface that can be used with just Http2Headers and HttpHeaders.

Modifications:
- add an overload for HttpConversionUtil.addHttp2ToHttpHeaders which does not take FullHttpMessage

Result:
An overload for HttpConversionUtil.addHttp2ToHttpHeaders exists which does not require FullHttpMessage.

2dde3a386b [#3687] Correctly store WebSocketServerHandshaker in Channel attributes
Motivation:

As we stored the WebSocketServerHandshaker in the ChannelHandlerContext it was always null and so no close frame was send if WebSocketServerProtocolHandler was used.

Modifications:

Store WebSocketServerHAndshaker in the Channel attributes and so make it visibile between different handlers.

Result:

Correctly send close frame.

f89dfb0bd5 Deprecation cleanup for HTTP headers
Motivaion:
The HttpHeaders and DefaultHttpHeaders have methods deprecated due to being removed in future releases, but no replacement method to use in the current release. The deprecation policy should not be so aggressive as to not provide any non-deprecated method to use.

Modifications:
- Remove deprecated annotations and javadocs from methods which are the best we can do in terms of matching the master's api for 4.1

Result:
There should be non-deprecated methods available for HttpHeaders in 4.1.

7049d8debb Add validateHeaders and headersToLowerCase options for SPDY
Motivation:

Related to issue #4185.

HTTP has the option to disable header validation for optimisation purposes.  Introduce the same option for SPDY headers.
Also, optimise SpdyHttpEncoder by allowing the user to specify whether or not the encoder needs to convert header names to lowercase.

Modifications:

Added flags for validation and conversion.

Result:

SpdyHeader validation and conversion can be disabled.

070f1470e8 [#4185] SpdyHttpEncoder fails to convert HttpResponse to SpdyFrame
Motivation:

When SpdyHttpEncoder attempts to create an SpdyHeadersFrame from a HttpResponse an IllegalArgumentException is thrown if the original HttpResponse contains a header that includes uppercase characters. The IllegalArgumentException is thrown due to the additional validation check introduced by #4047.

Previous versions of the SPDY codec would handle this by converting the HTTP header name to lowercase before adding the header to the SpdyHeadersFrame.

Modifications:

Convert the header name to lowercase before adding it to SpdyHeaders

Result:

SpdyHttpEncoder can now convert a valid HttpResponse into a valid SpdyFrame
