3e9f617504 Deduplicate and simplify code in HttpPostMultipartRequestDecoder
Motivation:

- A `HttpPostMultipartRequestDecoder` contains two pairs of the same methods: `readFileUploadByteMultipartStandard`+`readFileUploadByteMultipart` and `loadFieldMultipartStandard`+`loadFieldMultipart`.
- These methods use `NotEnoughDataDecoderException` to detecting not last data chunk (exception handling is very expensive).
- These methods can be greatly simplified.
- Methods `loadFieldMultipart` and `loadFieldMultipartStandard` has an unnecessary catching for the `IndexOutOfBoundsException`.

Modifications:

- Remove duplicate methods.
- Replace handling `NotEnoughDataDecoderException` by the return of a boolean result.
- Simplify code.

Result:

The code is cleaner and easier to support. Less exception handling logic.

f1e14d0cb2 Only add / to uri if really needed.
Motivation:

We not need to include the start index in the check. See https://github.com/netty/netty/pull/6924#discussion_r125263918

Modifications:

Change <= to <

Result:

More correct code.

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.

ba3616da3e Apply appropriate methods for writing CharSequence into ByteBuf
Motivation:

1. `ByteBuf` contains methods to writing `CharSequence` which optimized for UTF-8 and ASCII encodings. We can also apply optimization for ISO-8859-1.
2. In many places appropriate methods are not used.

Modifications:

1. Apply optimization for ISO-8859-1 encoding in the `ByteBuf#setCharSequence` realizations.
2. Apply appropriate methods for writing `CharSequences` into buffers.

Result:

Reduce overhead from string-to-bytes conversion.

d672a5a483 Optimizations in QueryStringEncoder
Motivation:

A life cycle of QueryStringEncoder is simple: create, append params, convert to String. Current realization collect params in the list, and calculate an URI string in `toString` method. We can simplify this: don't store params to the list, and immediately append parameters to the `StringBuilder`.

Modifications:

- Remove list for params and remove a tuple class `Param`.
- Use one common `StringBuilder` and append parameters into it.
- Resolve `TODO` in the `encodeParam` method.

Result:

Less allocations (no `ArrayList`, no `Param` tuples). Second `toString` call is faster.

01eb428b39 Move methods for decode hex dump into StringUtil
Motivation:

PR #6811 introduced a public utility methods to decode hex dump and its parts, but they are not visible from netty-common.

Modifications:

1. Move the `decodeHexByte`, `decodeHexDump` and `decodeHexNibble` methods into `StringUtils`.
2. Apply these methods where applicable.
3. Remove similar methods from other locations (e.g. `HpackHex` test class).

Result:

Less code duplication.

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.

b8a418d53d Remove redundant code block in HttpPostRequestEncoder and make some cleanup
Motivation:

The class `HttpPostRequestEncoder` has minor issues:
- The `encodeNextChunkMultipart()` method contains two identical blocks of code with a difference only in the cast interfaces: `Attribute` vs `HttpData`. Because the `Attribute` is extended by `HttpData`, the block with the `Attribute` can be safely deleted.
- The `getNewMultipartDelimiter()` method contains a redundant `toLowerCase()`.
- The `addBodyFileUploads()` method throws `NPE` instead of `IllegalArgumentException`.

Modifications:

- Remove duplicated code block from `encodeNextChunkMultipart()`.
- Remove redundant `toLowerCase()` from `getNewMultipartDelimiter()`.
- Replace `NPE` with `IllegalArgumentException` in `addBodyFileUploads()`.
- Use `ObjectUtil#checkNotNull` where possible.

Result:

More correct and clean code.

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.

b03b0f22d1 Removing a SeekAheadNoBackArrayException to avoid exception handling
Motivation:

A `SeekAheadNoBackArrayException` used as check for `ByteBuf#hasArray`. The catch of exceptions carries a large overhead on stack trace filling, and this should be avoided.

Modifications:

- Remove the class `SeekAheadNoBackArrayException` and replace its usage with `if` statements.
- Use methods from `ObjectUtils` for better readability.
- Make private methods static where it make sense.
- Remove unused private methods.

Result:

Less of exception handling logic, better performance.

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.

b419bd152a Handle the possibility of HTTP/0.9 with a better error message
Motivation

RFC 1945 (see section 3.1) says that request lines may not have a version in which case the request is assumed to be HTTP/0.9. We don't necessarily want to support that but the existing Exception should indicate the possibility of the request being HTTP/0.9 and give the user a chance to track it down.

Modifications

Indicate in the Exception's message that the request is possibly HTTP/0.9.

Result

Fixes #6739

This RFC has currently the state Proposed Standard since 2 years, but the status code is already handle by all browsers (Chrome, Firefox, Edge, Safari, …).
To let developer handles easily this status code, it is added into this list.

Modifications:

Added this status code in the list of all status codes and changed the valudOf() method

Result:

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.

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].

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

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.

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).

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.

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

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
Result:

Motivation:
code assumes a numeric value of 0 means no digits were read between separators, which fails for timestamps like 00:00:00.
also code accepts invalid timestamps like 0:0:000

Modifications:
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:

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

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

Avoid confusion about dependencies for HttpObjectAggregator on the pipeline.

- 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

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:

Create an invalid message with a PrematureChannelClosureException as cause when the channel is closed while we decode the headers.

Result:

Correct message sequence preserved and correct DecoderResult if the channel is closed while decode headers.

844976a0a2 Ensure the same ByteBufAllocator is used in the EmbeddedChannel when compress / decompress. Related to [#5294]
Motivation:

The user may specify to use a different allocator then the default. In this case we need to ensure it is shared when creating the EmbeddedChannel inside of a ChannelHandler

Modifications:

Use the config of the "original" Channel in the EmbeddedChannel and so share the same allocator etc.

Result:

Same type of buffers are used.

7b25402e80 Add CompositeByteBuf.addComponent(boolean ...) method to simplify usage
Motivation:

At the moment the user is responsible to increase the writer index of the composite buffer when a new component is added. We should add some methods that handle this for the user as this is the most popular usage of the composite buffer.

Modifications:

Add new methods that autoamtically increase the writerIndex when buffers are added.

Result:

Easier usage of CompositeByteBuf.

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.

0035630bd0 We need to ensure we correct reset decoder in decodeLast() to not produce multiple LastHttpContent instances.
Motivation:

We missed to reset the decoder when asked for it in HttpObjectDecoder and so sometimes could produce more then one LastHttpContent in a sequence during channelInactive.

This did show up as AssertionError:

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.

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.

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.

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.
