Replace toArray(new T[size]) with toArray(new T[0]) to eliminate zero-out and allow the VM to optimize. (#8075)
Motivation:

Using toArray(new T[0]) is usually the faster aproach these days. We should use it.

See also https://shipilev.net/blog/2016/arrays-wisdom-ancients/#_conclusion.

Modifications:

Replace toArray(new T[size]) with toArray(new T[0]).

Result:

Faster code.

fa4e28ba1c Fix random number generators in WebSocketUtil
Motivation:

Implementation of WebSocketUtil/randomNumber is incorrect and might violate
the API returning values > maximum specified.

Modifications:

* WebSocketUtil/randomNumber is reimplemented, the idea of the solution described
  in the comment in the code

* Implementation of WebSocketUtil/randomBytes changed to nextBytes method

* PlatformDependet.threadLocalRandom is used instead of Math.random to improve efficiency

* Added test cases to check random numbers generator

* To ensure corretness, we now assert that min < max when generating random number

Result:

WebSocketUtil/randomNumber always produces correct result.

4c709be1ab Print correct invalid character after unwrapping value in CookieEncoder
Motivation:

If a wrapped cookie value with an invalid charcater is passed to the strict
encoder, an exception is thrown on validation but the error message contains
a character at the wrong position.

Modifications:

Print `unwrappedValue.charAt(pos)` instead of `value.charAt(pos)`.

Result:

The exception indicates the correct invalid character in the unwrapped cookie.

48911e0b63 Set (and override) websocket handshake headers after custom headers (#7975)
Motivation:

Currently, when passing custom headers to a WebSocketClientHandshaker,
if values are added for headers that are reserved for use in the
websocket handshake performed with the server, these custom values can
be used by the server to compute the websocket handshake challenge. If
the server computes the response to the challenge with the custom header
values, rather than the values computed by the client handshaker, the
handshake may fail.

Modifications:

Update the client handshaker implementations to add the custom header
values first, and then set the reserved websocket header values.

Result:

Reserved websocket handshake headers, if present in the custom headers
passed to the client handshaker, will not be propagated to the server.
Instead the client handshaker will propagate the values it generates.

Fixes #7973.

9a3311506e Run the WebSocketClientHandshaker08Test on the 08 implementation (#7974)
Motivation:

The websockets abstract test suite does not run against the 08
implementation in the 08 version of the test suite.

Modifications:

Update the WebSocketClientHandshaker08Test to instantiate a new
WebSocketClientHandshaker08 rather than an 07 handshaker.

Result:

The WebSocketClientHandshaker08Test now tests the 08 implementation.

19d1f4ea62 Propagate pong frames in WebSocketProtocolHandler (#7955)
Motivation:

Currently, on recipt of a PongWebSocketFrame, the
WebSocketProtocolHandler will drop the frame, rather than passing it
along so it can be referenced by other handlers.

Modifications:

Add boolean field to WebSocketProtocolHandler to indicate whether Pong
frames should be dropped or propagated, defaulting to "true" to preserve
existing functionality.

Add new constructors to the client and server implementations of
WebSocketProtocolHandler that allow for overriding the behavior for the
handling of Pong frames.

Result:

PongWebSocketFrames are passed along the channel, if specified.

Correctly handle responses with status 205 and payload. (#7891)
Motivation:

HTTP responses with status of 205 should not contain a payload. We should enforce this.

Modifications:

Correctly handle responses with status 205 and payload by set Content-Length: 0 header and stripping out the content.

Result:

Allow to call AbstractDiskHttpData.setContent(Unpooled.EMPTY_BUFFER) multiple times. (#7890)
Motivation:

It should be possible to call setContent(Unpooled.EMPTY_BUFFER) multiple times just like its possible to do the same with a non empty buffer.

Modifications:

- Correctly reset underlying storage if called multiple times.
- Add tests

f874a37ecb Fixes NPE in Corshandler for unauthorized prefligt requests (#7865)
Motivation:
NPE in `CorsHandler` if a pre-flight request is done using an Origin header which is not allowed by any `CorsConfig` passed to the handler on creation.

Modifications:
During the pre-flight, check the `CorsConfig` for `null` and handle it correctly by not returning any access-control header

Result:
No more NPE for pre-flight requests with unauthorized origins.

76c5f6cd03 Enable per origin Cors configuration (#7800)
Motivation:

Finer granularity when configuring CorsHandler, enabling different policies for different origins.

Modifications:

The CorsHandler has an extra constructor that accepts a List<CorsConfig> that are evaluated sequentially when processing a Cors request

Result:

The changes don't break backwards compatibility. The extra ctor can be used to provide more than one CorsConfig object.

741602050f Don't replace all 'connection' headers when sending h2c upgrade request (#7824)
Motivation:

There may be meaningful 'connection' headers that exist on a request
that is used to attempt a HTTP/1.x upgrade request that will be
clobbered.

Modifications:

HttpClientUpgradeHandler uses the `HttpHeaders.add` instead of
`HttpHeaders.set` when adding the 'upgrade' field.

Result:

Fixes #7823, existing 'connection' headers are preserved.

b309271e49 HttpServerUpgradeHandler shouldn't wait for flush to reshape pipeline
Motivation:

There is a race between both flushing the upgrade response and receiving
more data before the flush ChannelPromise can fire and reshape the
pipeline. Since We have already committed to an upgrade by writing the
upgrade response, we need to be immediately prepared for handling the
next protocol.

Modifications:

The pipeline reshaping logic in HttpServerUpgradeHandler has been moved
out of the ChannelFutureListener attached to the write of the upgrade
response and happens immediately after the writeAndFlush call, but
before the method returns.

Result:

The pipeline is no longer subject to receiving more data before the
pipeline has been reformed.

d60cd0231d HttpProxyHandler generates invalid CONNECT url and Host header when address is resolved
Motivation:

HttpProxyHandler uses `NetUtil#toSocketAddressString` to compute
CONNECT url and Host header.

The url is correct when the address is unresolved, as
`NetUtil#toSocketAddressString` will then use
`getHoststring`/`getHostname`. If the address is already resolved, the
url will be based on the IP instead of the hostname.

There’s an additional minor issue with the Host header: default port
443 should be omitted.

Modifications:

* Introduce NetUtil#getHostname
* Introduce HttpUtil#formatHostnameForHttp to format an
InetSocketAddress to
HTTP format
* Change url computation to favor hostname instead of IP
* Introduce HttpProxyHandler ignoreDefaultPortsInConnectHostHeader
parameter to ignore 80 and 443 ports in Host header

Result:

HttpProxyHandler performs properly when connecting to a resolved address

06dcca1dbc When the response exceeds the threshold, it will be compressed
Motivation:

When the response is very small, compression will inflate the response.

Modifications:

Add filed io.netty.handler.codec.http.HttpContentCompressor#compressThreshold that control whether the HTTP response should be compressed.

Result:

Fixes #7660.

b640797de1 Fix HttpPostMultipartRequestDecoder.splitMultipartHeader() String index out of range: -1 with empty header
Motivation:

A Malformed empty header value (e.g. Content-Type: \r\n) will trigger a String index out of range
while trying to parse the multi-part request, using the HttpPostMultipartRequestDecoder.

Modification:

Ensure that the substring() method is called passing the endValue >= valueStart.
In case of an empty header value, the empty header value associated with the header key will be returned.

Result:

Fixes #7620

HttpResponseStatus object allocation reduction
Motivation:
Usages of HttpResponseStatus may result in more object allocation then necessary due to not looking for cached objects and the AsciiString parsing method not being used due to CharSequence method being used instead.

Modifications:
- HttpResponseDecoder should attempt to get the HttpResponseStatus from cache instead of allocating a new object
- HttpResponseStatus#parseLine(CharSequence) should check if the type is AsciiString and redirect to the AsciiString parsing method which may not require an additional toString call
- HttpResponseStatus#parseLine(AsciiString) can be optimized and doesn't require and may not require object allocation

Result:
Less allocations when dealing with HttpResponseStatus.

2b4f667791 Fix DefaultHttpDataFactory cleanup bug
Motivation:

DefaultHttpDataFactory uses HttpRequest as map keys.

Because of the implementation of "hashCode"" and "equals" in DefaultHttpRequest,
if we use normal maps, HttpDatas of different requests may end up in the same map entry,
causing cleanup bug.

Consider this example:
- Suppose that request1 is equal to request2, causing their HttpDatas to be stored in one single map entry.
- request1 is cleaned up first, while request2 is still being decoded.
- Consequently request2's HttpDatas are suddenly gone, causing NPE, or worse loss of data.

This bug can be reproduced by starting the HttpUploadServer example,
then run this command:
ab -T 'application/x-www-form-urlencoded' -n 100 -c 5 -p post.txt http://localhost:8080/form

post.txt file content:
a=1&b=2

There will be errors like this:

7aca99f986 DefaultHttpHeader.names().toArray(...) may throw ArrayStoreException
Motivation:

DefaultHttpHeader.names() exposes HTTP header names as a Set<String>. Converting the resulting set to an array using toArray(String[]) throws an exception: java.lang.ArrayStoreException: io.netty.util.AsciiString.

Modifications:

- Remove our custom implementation of toArray(...) (and others) by just extending AbstractCollection.
- Add unit test

Result:

e420f857fa Optimize DefaultHeaders#toString and implement HttpHeaders#toString
Motivation:

For debugging/logging purpose, it would be convenient to have
HttpHeaders#toString implemented.

DefaultHeaders does implement toString be the implementation is suboptimal and allocates a Set for the names and Lists for values.

Modification:

* Introduce HeadersUtil#toString that provides a convenient optimized helper to implement toString for various headers implementations
* Have DefaultHeaders#toString and HttpHeaders#toString delegate their toString implementation to HeadersUtil

Result:

Convenient HttpHeaders#toString. Optimized DefaultHeaders#toString.

7f4ade7e7d Correctly propagate channelInactive even if cleanup throws
Motivation:

Its possible that cleanup() will throw if invalid data is passed into the wrapped EmbeddedChannel. We need to ensure we still call channelInactive(...) in this case.

Modifications:

- Correctly forward Exceptions caused by cleanup()
- Ensure all content is released when cleanup() throws
- Add unit tests

Result:

Correctly handle the case when cleanup() throws.

0a47c590fe HttpHeaders valuesIterator and contains improvements
Motivation:
In order to determine if a header contains a value we currently rely
upon getAll(..) and regular expressions. This operation is commonly used
during the encode and decode stage to determine the transfer encoding
(e.g. HttpUtil#isTransferEncodingChunked). This operation requires an
intermediate collection and possibly regular expressions for the
CombinedHttpHeaders use case which can be expensive.

Modifications:
- Add a valuesIterator to HttpHeaders and specializations of this method
for DefaultHttpHeaders, ReadOnlyHttpHeaders, and CombinedHttpHeaders.

Result:
Less intermediate collections and allocation overhead when determining
if HttpHeaders contains a name/value pair.

48b4502d1d Move EmptyHttpHeaders.INSTANCE initialization to inner class.
Motivation:

If the HttpUtil class is initialized before HttpHeaders or
EmptyHttpHeaders, EmptyHttpHeaders.INSTANCE will be null. This
can lead to NPEs in code that relies on this field being
non-null. One example is the
LastHttpContent.EMPTY_LAST_CONTENT.trailingHeaders method.

Modifications:

- Move HttpUtil.EMPTY_HEADERS to a private static final inner class
  of EmptyHttpHeaders called InstanceInitializer.
- Add tests, that when run in isolation, validate the fix for the issue.

Result:

Any initialization order of HttpUtil, EmptyHttpHeaders or
HttpHeaders will result in EmptyHttpHeaders.INSTANCE being initialized
correctly.

72a216625f Correctly handle 205 Reset Content response with transfer-encoding
Motivation:

According to RFC 7231 the server may choose to:
```
indicate a zero-length payload for the response by including a
Transfer-Encoding header field with a value of chunked and a message
body consisting of a single chunk of zero-length
```
https://tools.ietf.org/html/rfc7231#page-53

In such cases the exception below appears during decoding phase:
```
java.lang.IllegalArgumentException: invalid version format: 0
	at io.netty.handler.codec.http.HttpVersion.<init>(HttpVersion.java:121)
	at io.netty.handler.codec.http.HttpVersion.valueOf(HttpVersion.java:76)
	at io.netty.handler.codec.http.HttpResponseDecoder.createMessage(HttpResponseDecoder.java:118)
	at io.netty.handler.codec.http.HttpObjectDecoder.decode(HttpObjectDecoder.java:219)
```

Modifications:

HttpObjectDecoder.isContentAlwaysEmpty specifies content NOT empty
when 205 Reset Content response

Result:

There is no `IllegalArgumentException: invalid version format: 0`
when handling 205 Reset Content response with transfer-encoding

3554646a60 Correctly convert empty HttpContent to ByteBuf
Motivation:

93130b172a introduced a regression where we not "converted" an empty HttpContent to ByteBuf and just passed it on in the pipeline. This can lead to the situation that other handlers in the pipeline will see HttpContent instances which is not expected.

Modifications:

- Correctly convert HttpContent to ByteBuf when empty
- Add unit test.

Result:

Handlers in the pipeline will see the expected message type.

8618a3351c ReadOnlyHttpHeaders
Motivation:
For use cases that create headers, but do not need to modify them a read only variant of HttpHeaders would be useful and may be able to provide better iteration performance for encoding.

Modifications:
- Introduce ReadOnlyHttpHeaders that is backed by a flat array

Result:
ReadOnlyHttpHeaders exists for non-modifiable HttpHeaders use cases.

93130b172a HttpObjectEncoder and MessageAggregator EMPTY_BUFFER usage
Motivation:
HttpObjectEncoder and MessageAggregator treat buffers that are not readable special. If a buffer is not readable, then an EMPTY_BUFFER is written and the actual buffer is ignored. If the buffer has already been released then this will not be correct as the promise will be completed, but in reality the original content shouldn't have resulted in any write because it was invalid.

Modifications:
- HttpObjectEncoder should retain/write the original buffer instead of using EMPTY_BUFFER
- MessageAggregator should retain/write the original ByteBufHolder instead of using EMPTY_BUFFER

Result:
Invalid write operations which happen to not be readable correctly reflect failed status in the promise, and do not result in any writes to the channel.

7995afee8f Don't disable HttpObjectDecoder on upgrade from HTTP/1.x to HTTP/1.x over TLS
This change allows to upgrade a plain HTTP 1.x connection to TLS
according to RFC 2817. Switching the transport layer to TLS should be
possible without removing HttpClientCodec from the pipeline,
because HTTP/1.x layer of the protocol remains untouched by the switch
and the HttpClientCodec state must be retained for proper
handling the remainder of the response message,
per RFC 2817 requirement in point 3.3:

  Once the TLS handshake completes successfully, the server MUST
  continue with the response to the original request.

After this commit, the upgrade can be established by simply
inserting an SslHandler at the front of the pipeline after receiving
101 SWITCHING PROTOCOLS response, exactly as described in SslHander
documentation.

Modifications:
- Don't set HttpObjectDecoder into UPGRADED state if
  101 SWITCHING_PROTOCOLS response contains HTTP/1.0 or HTTP/1.1 in
  the protocol stack described by the Upgrade header.
- Skip pairing comparison for 101 SWITCHING_PROTOCOLS, similar
  to 100 CONTINUE, since 101 is not the final response to the original
  request and the final response is expected after TLS handshake.

Fixes #7293.

8aeba78ecc HttpPostMultipartRequestDecoder should decode header field parameters
Motivation:

I am receiving a multipart/form_data upload from a Mailgun webhook. This webhook used to send parts like this:

--74e78d11b0214bdcbc2f86491eeb4902
Content-Disposition: form-data; name="attachment-2"; filename="attached_�айл.txt"
Content-Type: text/plain
Content-Length: 32

This is the content of the file

--74e78d11b0214bdcbc2f86491eeb4902--
but now it posts parts like this:

--74e78d11b0214bdcbc2f86491eeb4902
Content-Disposition: form-data; name="attachment-2"; filename*=utf-8''attached_%D1%84%D0%B0%D0%B9%D0%BB.txt

This is the content of the file

--74e78d11b0214bdcbc2f86491eeb4902--
This new format uses field parameter encoding described in RFC 5987. More about this encoding can be found here.

Netty does not parse this format. The result is the filename is not decoded and the part is not parsed into a FileUpload.

Modification:

Added failing test in HttpPostRequestDecoderTest.java and updated HttpPostMultipartRequestDecoder.java
Refactored to please Netkins
Result:

Fixes:

HttpPostMultipartRequestDecoder identifies the RFC 5987 format and parses it.
Previous functionality is retained.

dcbbae7f90 Added QueryStringDecoder.rawPath() and rawQuery()
Motivation:

Before this commit, it is impossible to access the path component of the
URI before it has been decoded.  This makes it impossible to distinguish
between the following URIs:

/user/title?key=value
/user%2Ftitle?key=value

The user could already access the raw uri value, but they had to calculate
pathEndIdx themselves, even though it might already be cached inside
QueryStringDecoder.

Result:

The user can easily and efficiently access the undecoded path and query.

dc98eae5a5 Correct filling an origin header for WS client
Motivation:
An `origin`/`sec-websocket-origin` header value in websocket client is filling incorrect in some cases:
- Hostname is not converting to lower-case as prescribed by RFC 6354 (see [1]).
- Selecting a `http` scheme when source URI has `wss`/`https` scheme and non-standard port.

Modifications:
- Convert uri-host to lower-case.
- Use a `https` scheme if source URI scheme is `wss`/`https`, or if source scheme is null and port == 443.

Result:
Correct filling an `origin` header for WS client.

50a067a8f7 Make methods 'static' where it possible
Motivation:

Even if it's a super micro-optimization (most JVM could optimize such
 cases in runtime), in theory (and according to some perf tests) it
 may help a bit. It also makes a code more clear and allows you to
 access such methods in the test scope directly, without instance of
 the class.

Modifications:

Add 'static' modifier for all methods, where it possible. Mostly in
test scope.

Result:

Cleaner code with proper 'static' modifiers.

70c5c48eab Correctly not write any body when 1xx, 204 or 304 is used as response status code.
Motivation:

We need to ensure we not write any body when a response with status code of 1xx, 204 or 304 is used as stated in rfc:
https://tools.ietf.org/html/rfc7230#section-3.3.3

Modifications:

- Correctly handle status codes
- Add unit tests

Result:

Correctly handle responses with 1xx, 204, 304 status codes.

52e19d5c63 Strip http 'expect' headers when expectation response is produced
Motivation:

HttpObjectAggregator differs from HttpServerExpectContinueHandler's handling
of expect headers by not stripping the 'expect' header when a response
is generated.

Modifications:

HttpObjectAggregator now removes the 'expect' header in cases where it generates
a response.

Result:

Consistent and correct behavior between HttpObjectAggregator and HttpServerExpectContinueHandler.

08748344d8 Fix NPEs in HttpPostRequestEncoder#nextChunk
Motivation:

HttpPostRequestEncoder maintains an internal buffer that holds the
current encoded data. There are use cases when this internal buffer
becomes null, the next chunk processing implementation should take
this into consideration.

Modifications:

- When preparing the last chunk if currentBuffer is null, mark
isLastChunkSent as true and send LastHttpContent.EMPTY_LAST_CONTENT
- When calculating the remaining size take into consideration that the
currentBuffer might be null
- Tests are based on those provided in the issue by @nebhale and @bfiorini

Result:

Fixes #5478

df568c739e Use ByteBuf#writeShort/writeMedium instead of writeBytes
Motivation:

1. Some encoders used a `ByteBuf#writeBytes` to write short constant byte array (2-3 bytes). This can be replaced with more faster `ByteBuf#writeShort` or `ByteBuf#writeMedium` which do not access the memory.
2. Two chained calls of the `ByteBuf#setByte` with constants can be replaced with one `ByteBuf#setShort` to reduce index checks.
3. The signature of method `HttpHeadersEncoder#encoderHeader` has an unnecessary `throws`.

Modifications:

1. Use `ByteBuf#writeShort` or `ByteBuf#writeMedium` instead of `ByteBuf#writeBytes` for the constants.
2. Use `ByteBuf#setShort` instead of chained call of the `ByteBuf#setByte` with constants.
3. Remove an unnecessary `throws` from `HttpHeadersEncoder#encoderHeader`.

Result:

A bit faster writes constants into buffers.

dd69a813d4 Performance improvement for HttpRequestEncoder. Insert char into the string optimized.
Motivation:

Right now HttpRequestEncoder does insertion of slash for url like http://localhost?pararm=1 before the question mark. It is done not effectively.

Modification:

Code:

new StringBuilder(len + 1)
                .append(uri, 0, index)
                .append(SLASH)
                .append(uri, index, len)
                .toString();
Replaced with:

new StringBuilder(uri)
                .insert(index, SLASH)
                .toString();
Result:

Faster HttpRequestEncoder. Additional small test. Attached benchmark in PR.

9ad74e72e6 Remove content-length header leniency
Motivation:

If the content-length does not parse as a number, leniency causes this
to instead be parsed as the default value. This leads to bodies being
silently ignored on requests which can be incredibly dangerous. Instead,
if the content-length header is invalid, an exception should be thrown
for upstream handling.

Modifications:

This commit removes the leniency in parsing the content-length header by
allowing a number format exception, if thrown, to escape from the method
rather than falling back to the default value.

Result:

In invalid content-length header will not be silently ignored.

81f9434ec7 Added test for multi header, HttpObjectDecoder performance improvement for multi header, removed empty else block.
Motivation:

For multi-line headers HttpObjectDecoder uses StringBuilder.append(a).append(b) pattern that could be easily replaced with regular a + b. Also oparations with a and b moved out from concat operation to make it friendly for StringOptimizeConcat optimization and thus - faster.

Modification:

StringBuilder.append(a).append(b) reaplced with a + b. Operations with a and b moved out from concat oparation.

Result:
Code simpler to read and faster.

629b83e0a5 Move QueryStringDecoder.decodeHexByte into ByteBufUtil
Motivations:
1. There are duplicated implementations of decoding hex strings. #6797
2. ByteBufUtil.HexUtil.decodeHexDump does not handle substring start
index properly and does not decode hex byte rigorously.

Modifications:
1. Function decodeHexByte is moved from QueryStringDecoder into ByteBufUtil.
2. ByteBufUtil.HexUtil.decodeHexDump is changed to use decodeHexByte.
3. Tests are Updated accordingly.

Result:
Fixed #6797 and made hex decoding functions more robust.

9fa3e556f3 Adjust Content-Length header when encoding Full Responses
Motivation:
If a full HttpResponse with a Content-Length header is encoded by the HttpContentEncoder subtypes the Content-Length header is removed and the message is set to Transfer-Encoder: chunked. This is an unnecessary loss of information about the message content.

Modifications:
- If a full HttpResponse has a Content-Length header, the header is adjusted after encoding.

Result:
Complete messages continue to have the Content-Length header after encoding.

270e9d66c5 Fixes in QueryStringDecoder
Motivation:

QueryStringDecoder has several problems:
- doesn't decode correctly path part with `+` (plus) sign in it,
- doesn't cut a `fragment` (after `#`) from query string (see RFC 3986),
- doesn't work correctly with encoding,
- treat `%%` as a percent character escaping (it's don't described in RFC).

Modifications:

- leave `+` chars in a `path` part of uri string,
- ignore `fragment` part (after `#`),
- correctly work with encoding.
- don't treat `%%` as escaping for the `%`.

Result:

Fixed issues from #6745.

a093b89bfe Allow HTTP decoding post CONNECT in HttpClientCode
__Motivation__

`HttpClientCodec` skips HTTP decoding on the connection after a successful HTTP CONNECT response is received.
 This behavior follows the spec for a client but pragmatically, if one creates a client to use a proxy transparently, the codec becomes useless after HTTP CONNECT.
 Ideally, one should be able to configure whether HTTP CONNECT should result in pass-through or not. This will enable client writers to continue using HTTP decoding even after HTTP CONNECT.

 __Modification__

 Added overloaded constructors to accept `parseHttpPostConnect`. If this parameter is `true` then the codec continues decoding even after a successful HTTP CONNECT.

 Also fixed a bug in the codec that was incrementing request count post HTTP CONNECT but not decrementing it on response. Now, the request count is only incremented if the codec is not `done`.

 __Result__

 Easier usage by HTTP client writers who wants to connect to a proxy but still decode HTTP for their users for subsequent requests.

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.

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.

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).

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).

Result:

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.

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.

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

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"

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

3451b3cbb3 Cookie name must be case sensitive
Motivation:

RFC 6265 does not state that cookie names must be case insensitive.

Modifications:

Fix io.netty.handler.codec.http.cookie.DefaultCookie#equals() method to
use case sensitive String#equals() and String#compareTo().

Result:

It is possible to parse several cookies with same names but with
different cases.

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:
Fixes https://github.com/netty/netty/issues/5582

835f901d5f Fix #5590 QueryStringDecoder#path should decode the path info
Motivation:

Currently, QueryStringDecoder#path simply returns the path info as is, without decoding it as the Javadoc states.

Modifications:

* Make QueryStringDecoder#path decode the path info.
* Add tests to QueryStringDecoderTest.

Result:

QueryStringDecoder#path now decodes the path info as expected.

d964bf6f18 Remove usages of deprecated methods group() and childGroup().
Motivation:

These methods were recently deprecated. However, they remained in use in several locations in Netty's codebase.

Modifications:

Netty's code will now access the bootstrap config to get the group or child group.

Result:

No impact on functionality.

- Add unit tests.

Result:

Generate correct header.

ee0897a1d9 HttpContentDecompressor should change decompressed requests to chunked encoding. Fixes issue #5428
`HttpContentDecoder` was removing `Content-Length` header but not adding a `Transfer-Encoding` header which goes against the HTTP spec.

Added `Transfer-Encoding` header with value `chunked` when `Content-Length` is removed.
Modified existing unit test to also check for this condition.

Compliance with HTTP spec.

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.

f5eea4698d Fix possible NPE in HttpCunkedInput if wrapped ChunkedInput.readChunk(...) return null.
Motivation:

Its completly fine for ChunkedInput.readChunk(...) to return null to indicate there is currently not any data to read. We need to handle this in HttpChunkedInput to not produce a NPE when constructing the HttpContent.

Modifications:

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

Result:

No more NPE.
