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:

Fixes https://github.com/netty/netty/issues/7888

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

Result:

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.

CorsHandler.write(...) should not cause a flush. (#7839)
Motivation:

Unnecessary flushes reduce the amount of flush coalescing that can happen at higher levels and thus can increase number of packets (because of TCP_NODELAY) and lower throughput (due to syscalls, TLS frames, etc)

Modifications:

Replace writeAndFlush(...) with write(...)

Result:

Fixes https://github.com/netty/netty/issues/7837.

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:

942b993f2b Only enable validation of headers if original headers were validating as well.
Motiviation:

In our replace(...) methods we always used validation for the newly created headers while the original headers may not use validation at all.

Modifications:

- Only use validation if the original headers used validation as well.
- Ensure we create a copy of the headers in replace(...).

Result:

e8540c2b7a Adding stable JDK9 module names that follow reverse-DNS style
Automatic-Module-Name entry provides a stable JDK9 module name, when Netty is used in a modular JDK9 applications. More info: http://blog.joda.org/2017/05/java-se-9-jpms-automatic-modules.html

When Netty migrates to JDK9 in the future, the entry can be replaced by actual module-info descriptor.

Modification:

The POM-s are configured to put the correct module names to the manifest.

Result:

Fixes #7218.

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

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.

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

Result:

93b144b7b4 HttpMethod#valueOf improvement
Motivation:
HttpMethod#valueOf shows up on profiler results in the top set of
results. Since it is a relatively simple operation it can be improved in
isolation.

Modifications:
- Introduce a special case map which assigns each HttpMethod to a unique
index in an array and provides constant time lookup from a hash code
algorithm. When the bucket is matched we can then directly do equality
comparison instead of potentially following a linked structure when
HashMap has hash collisions.

Result:
~10% improvement in benchmark results for HttpMethod#valueOf

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:

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.
