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:

Modifications:

Keep identity of requests by using IdentityHashMap

Result:

DefaultHttpDataFactory is fixed.

The ConcurrentHashMap is replaced with a synchronized map, but I think the performance won't be affected much in real web apps.

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

Result:

Fixes [#7428].

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.

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:
- 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.

1b0a545921 Do not send Content-Length: 0 on 101 responses.
Motivation:

During code read of the Netty codebase I noticed that the Netty
HttpServerUpgradeHandler unconditionally sets a Content-Length: 0
header on 101 Switching Protocols responses. This explicitly
contravenes RFC 7230 Section 3.3.2 (Content-Length), which notes
that:

    A server MUST NOT send a Content-Length header field in any
    response with a status code of 1xx (Informational) or 204
    (No Content).

While it is unlikely that any client will ever be confused by
this behaviour, there is no reason to contravene this part of the
specification.

Modifications:

Removed the line of code setting the header field and changed the
only test that expected it to be there.

Result:

When performing the server portion of HTTP upgrade, the 101
Switching Protocols response will no longer contain a
Content-Length: 0 header field.

940f15f0d2 Use predefined HttpResponseStatus constant instead of hardcoded 101 code
Motivation:

#7269 removed an unnecessary instanciation for verifying WebSocket
handshake status code.
But it uses a hardcoded status code value for 101 instead of using the
intended `HttpResponseStatus#SWITCHING_PROTOCOLS` constant.

Modidication:

Compare actual `HttpResponseStatus` against predefined constant. Note
that `HttpResponseStatus#equals` is implemented in respect with the RFC
(only honor code, not text) so it’s intended to be used this way.

Result:

Cleaner code, use intended constant instead of hard coded value.

78786e6052 Remove unnecessary instantiation of HttpResponseStatus
Motivation:
- In the `HttpResponseStatus#equals` checks only status code. No need to create new instance of `HttpResponseStatus` for comparison with response status.
- The RFC says: `the HTTP version and reason phrase aren't important` [1].

Modifications:
Use comparison by status code without creating new `HttpResponseStatus`.

Result:
Less allocations, more clear code.

9bd6d8129e HttpObjectEncoder buffer size estimation
Motivation:
HttpObjectEncoder allocates a new buffer when encoding the initial line and headers, and also allocates a buffer when encoding the trailers. The allocation always uses the default size of 256. This may lead to consistent under allocation and require a few resize/copy operations which can cause GC/memory pressure.

Modifications:
- Introduce a weighted average which tracks the historical size of encoded data and uses this as an estimate for future buffer allocations

Result:
Better approximation of buffer sizes.

123e07ca80 Revert "Only call ctx.fireChannelReadComplete() if ByteToMessageDecoder decoded at least one message."
This reverts commit d63bb4811e as this not covered correctly all cases and so could lead to missing fireChannelReadComplete() calls. We will re-evalute d63bb4811e and resbumit a pr once we are sure all is handled correctly

4875a2aad4 Immediate caching the strings wrapped to AsciiString
Motivation:
The `AsciiString#toString` method calculate string value and cache it into field. If an `AsciiString` created from the `String` value, we can avoid rebuilding strings if we cache them immediately when creating `AsciiString`. It would be useful for constants strings, which already stored in the JVMs string table, or in cases where an unavoidable `#toString `method call is assumed.

Modifications:
- Add new static method `AsciiString#cache(String)` which save string value into cache field.
- Apply a "benign" data race in the `#hashCode` and `#toString` methods.

Result:
Less memory usage in some `AsciiString` use cases.

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.

d63bb4811e Only call ctx.fireChannelReadComplete() if ByteToMessageDecoder decoded at least one message.
Motivation:

Its wasteful and also confusing that channelReadComplete() is called even if there was no message forwarded to the next handler.

Modifications:

- Only call ctx.fireChannelReadComplete() if at least one message was decoded
- Add unit test

Result:

Less confusing behavior. Fixes [#4312].
