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.

Motivation:

Fix the regression recently introduced that causes already encoded responses to be encoded again as gzip

Modification:

instead of just looking for IDENTITY, anything set for Content-Encoding should be respected and left as-is

added unit tests to capture this use case

Result:

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:

Status code 308 included

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.

174f4ea005 HttpServerKeepAliveHandler doesn't correctly handle VoidChannelPromise
Motivation:

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

Modification:

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

Result:

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

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

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

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

Result:

More flexible methods set with a good code reusing.

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

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

Modifications:

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

Result:

Closes [#3063].

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

Modifications:

Introduce the HttpServerExpectContinueHandler handler to make it easier.

Result:

Less boiler plate for http application authors.

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

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

Modifications:

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

Result:

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

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

Modifications:
- HttpServerKeepAliveHandler#isSelfDefinedMessageLength should account for 204 respones

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

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

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

Modification:

Fix type casting

Result:

Non-latin characters work.

9c1a191696 Trim optional white space in CombinedHttpHeaders values
Motivation:

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

Modification:

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