caa1505020 Get uploaded size while upload is in progress
Proposal to fix issue #3636

Motivations:
Currently, while adding the next buffers to the decoder
(`decoder.offer()`), there is no way to access to the current HTTP
object being decoded since it can only be available currently once fully
decoded by `decoder.hasNext()`.
Some could want to know the progression on the overall transfer but also
per HTTP object.
While overall progression could be done using (if available) the global
Content-Length of the request and taking into account each HttpContent
size, the per HttpData object progression is unknown.

Modifications:
1) For HTTP object, `AbstractHttpData` has 2 protected properties named
`definedSize` and `size`, respectively the supposely final size and the
current (decoded until now) size.
This provides a new method `definedSize()` to get the current value for
`definedSize`. The `size` attribute is reachable by the `length()`
method.

Note however there are 2 different ways that currently managed the
`definedSize`:
a) `Attribute`: it is reset each time the value is less than actual
(when a buffer is added, the value is increased) since the final length
is not known (no Content-Length)
b) `FileUpload`: it is set at startup from the lengh provided

So these differences could lead in wrong perception;
a) `Attribute`: definedSize = size always
b) `FileUpload`: definedSize >= size always

Therefore the comment tries to explain clearly the different behaviors.

2) In the InterfaceHttpPostRequestDecoder (and the derived classes), I
add a new method: `decoder.currentPartialHttpData()` which will return a
`InterfaceHttpData` (if any) as the current `Attribute` or `FileUpload`
(the 2 generic types), which will allow then the programmer to check
according to the real type (instance of) the 2 methods `definedSize()`
and `length()`.

This method check if currentFileUpload or currentAttribute are null and
returns the one (only one could be not null) that is not null.

Note that if this method returns null, it might mean 2 situations:
a) the last `HttpData` (whatever attribute or file upload) is already
finished and therefore accessible through `next()`
b) there is not yet any `HttpData` in decoding (body not yet parsed for
instance)

Result:
The developper has more access and therefore control on the current
upload.
The coding from developper side could looks like in the example in
HttpUloadServerHandler.

0ca65f1373 Lazily instantiate HttpServerUpgradeHandler.UpgradeCodec
Related: #3814

Motivation:

To implement the support for an upgrade from cleartext HTTP/1.1
connection to cleartext HTTP/2 (h2c) connection, a user usually uses
HttpServerUpgradeHandler.

It does its job, but it requires a user to instantiate the UpgradeCodecs
for all supported protocols upfront. It means redundancy for the
connections that are not upgraded.

Modifications:

- Change the constructor of HttpServerUpgradeHandler
  - Accept UpgraceCodecFactory instead of UpgradeCodecs
- The default constructor of HttpServerUpgradeHandler sets the
  maxContentLength to 0 now, which shouldn't be a problem because a
  usual upgrade request is a GET.
- Update the examples accordingly

Result:

A user can instantiate Http2ServerUpgradeCodec and its related objects
(Http2Connection, Http2FrameReader/Writer, Http2FrameListener, etc) only
when necessary.

e9a2cac16d [#3869] Add unit test to ensure adding null header values is not allowed.
Motivation:

We need to ensure we never allow to have null values set on headers, otherwise we will see a NPE during encoding them.

Modifications:

Add unit test that shows we correctly handle null values.

Result:

0775089496 Replace SpdyOrHttpChooser and Http2OrHttpChooser with ApplicationProtocolNegotiationHandler
Motivation:

SpdyOrHttpChooser and Http2OrHttpChooser duplicate fair amount code with each other.

Modification:

- Replace SpdyOrHttpChooser and Http2OrHttpChooser with ApplicationProtocolNegotiationHandler
- Add ApplicationProtocolNames to define the known application-level protocol names

Result:

- Less code duplication
- A user can perform dynamic pipeline configuration that follows ALPN/NPN for any protocols.

afb46b926f Improve the API design of Http2OrHttpChooser and SpdyOrHttpChooser
Related: #3641 and #3813

Motivation:

When setting up an HTTP/1 or HTTP/2 (or SPDY) pipeline, a user usually
ends up with adding arbitrary set of handlers.

Http2OrHttpChooser and SpdyOrHttpChooser have two abstract methods
(create*Handler()) that expect a user to return a single handler, and
also have add*Handlers() methods that add the handler returned by
create*Handler() to the pipeline as well as the pre-defined set of
handlers.

The problem is, some users (read: I) don't need all of them or the
user wants to add more than one handler. For example, take a look at
io.netty.example.http2.tiles.Http2OrHttpHandler, which works around
this issue by overriding addHttp2Handlers() and making
createHttp2RequestHandler() a no-op.

Modifications:

- Replace add*Handlers() and create*Handler() with configure*()
- Rename getProtocol() to selectProtocol() to make what it does clear
- Provide the default implementation of selectProtocol()
- Remove SelectedProtocol.UNKNOWN and use null instead, because
  'UNKNOWN' is not a protocol
- Proper exception handling in the *OrHttpChooser so that the
  exception is logged and the connection is closed when failed to
  select a protocol
- Make SpdyClient example always use SSL. It was always using SSL
  anyway.
- Implement SslHandshakeCompletionEvent.toString() for debuggability
- Remove an orphaned class: JettyNpnSslSession
- Add SslHandler.applicationProtocol() to get the name of the
  application protocol
  - SSLSession.getProtocol() now returns transport-layer protocol name
    only, so that it conforms to its contract.

Result:

- *OrHttpChooser have better API.
- *OrHttpChooser handle protocol selection failure properly.
- SSLSession.getProtocol() now conforms to its contract.
- SpdyClient example works with SpdyServer example out of the box

757671b7cc Support empty http responses when using compression
Motivation:

Found a bug in that netty would generate a 20 byte body when returing a response
to an HTTP HEAD. the 20 bytes seems to be related to the compression footer.

RFC2616, section 9.4 states that responses to an HTTP HEAD MUST not return a message
body in the response.

Netty's own client implementation expected an empty response. The extra bytes lead to a
2nd response with an error decoder result:
java.lang.IllegalArgumentException: invalid version format: 14

Modifications:

Track the HTTP request method. When processing the response we determine if the response
is passthru unnchanged. This decision now takes into account the request method and passthru
responses related to HTTP HEAD requests.

Result:

Netty's http client works and better RFC conformance.

f6299d942c Minor ClientCookieDecoder improvements
Motivation:

* Path attribute should be null, not empty String, if it's passed as "Path=".
* Only extract attribute value when the name is recognized.
* Only extract Expires attribute value String if MaxAge is undefined as it has precedence.

Modification:

Modify ClientCookieDecoder.
Add "testIgnoreEmptyPath" test in ClientCookieDecoderTest.

Result:

More idyomatic Path behavior (like Domain).
Minor performance improvement in some corner cases.

61dced3dcd Proposal to fix issue #3768 (3.10)
Motivations:
When using HttpPostRequestEncoder and trying to set an attribute if a
charset is defined, currenlty implicit Charset.toStrng() is used, given
wrong format.
As in Android for UTF-16 = "com.ibm.icu4jni.charset.CharsetICU[UTF-16]".

Modifications:
Each time charset is used to be printed as its name, charset.name() is
used to get the canonical name.

Result:
Now get "UTF-16" instead.

97d871a755 Validate cookie name and value characters Motivation:
RFC6265 specifies which characters are allowed in a cookie name and value.

Netty is currently too lax, which can used for HttpOnly escaping.

Modification:

In ServerCookieDecoder: discard cookie key-value pairs that contain invalid characters.
In ClientCookieEncoder: throw an exception when trying to encode cookies with invalid characters.

Result:

The problem described in the motivation section is fixed.

62057f73d6 Fix handling of non-auto read for ByteToMessageDecoder and SslHandler
Motivation:

Our automatically handling of non-auto-read failed because it not detected the need of calling read again by itself if nothing was decoded. Beside this handling of non-auto-read never worked for SslHandler as it always triggered a read even if it decoded a message and auto-read was false.

This fixes [#3529] and [#3587].

Modifications:

- Implement handling of calling read when nothing was decoded (with non-auto-read) to ByteToMessageDecoder again
- Correctly respect non-auto-read by SslHandler

Result:

No more stales and correctly respecting of non-auto-read by SslHandler.

854859ba69 Change AggregatedFullHttpMessage to contain a content ByteBuf
Motivation:

Other implementations of FullHttpMessage allow .toString to be called after the Message has been released
This brings AggregatedFullHttpMessage into line with those impls.

Modifications:

- Changed AggregatedFullHttpMessage to no longer be a sub-class of DefaultByteBufHolder
- Changes AggregatedFullHttpMessage to implement ByteBufHolder
- Hold the content buffer internally to AggregatedFullHttpMessage
- Implement the required content() and release() methods that were missing
- Do not check refcnt when accessing content() (similar to DefaultFullHttpMessage)

Result:

A released AggregatedFullHttpMessage can have .toString called without throwing an exception

9a7a85dbe5 ByteString introduced as AsciiString super class
Motivation:
The usage and code within AsciiString has exceeded the original design scope for this class. Its usage as a binary string is confusing and on the verge of violating interface assumptions in some spots.

Modifications:
- ByteString will be created as a base class to AsciiString. All of the generic byte handling processing will live in ByteString and all the special character encoding will live in AsciiString.

Results:
The AsciiString interface will be clarified. Users of AsciiString can now be clear of the limitations the class imposes while users of the ByteString class don't have to live with those limitations.

61859eefa0 Safely encode Strings to ASCII
(Ported @luciferous's changes against 3.10)

Motivation:

The current implementation of the encoder writes each character of the
String as a single byte to the buffer, however not all characters are
mappable to a single byte.

Modifications:

If a character is outside the ASCII range, it's converted to '?'.

Result:

A safer encoder for String to ASCII, which substitutes unmappable
characters with'?'.

6d5c38897e Fix header and initial line length counting
Related: #3445

Motivation:

HttpObjectDecoder.HeaderParser does not reset its counter (the size
field) when it failed to find the end of line.  If a header is split
into multiple fragments, the counter is increased as many times as the
number of fragments, resulting an unexpected TooLongFrameException.

Modifications:

- Add test cases that reproduces the problem
- Reset the HeaderParser.size field when no EOL is found.

Result:

One less bug

5b1b334f01 When null origin is supported then credentials header must not be set.
Motivation:
Currently CORS can be configured to support a 'null' origin, which can
be set by a browser if a resources is loaded from the local file system.
When this is done 'Access-Control-Allow-Origin' will be set to "*" (any
origin). There is also a configuration option to allow credentials being
sent from the client (cookies, basic HTTP Authentication, client side
SSL). This is indicated by the response header
'Access-Control-Allow-Credentials' being set to true. When this is set
to true, the "*" origin is not valid as the value of
'Access-Control-Allow-Origin' and a browser will reject the request:
http://www.w3.org/TR/cors/#resource-requests

Modifications:
Updated CorsHandler's setAllowCredentials to check the origin and if it
is "*" then it will not add the 'Access-Control-Allow-Credentials'
header.

Result:
Is is possible to have a client send a 'null' origin, and at the same
time have configured the CORS to support that and to allow credentials
in that combination.

c53b8d5a85 Suggestion for supporting single header fields.
Motivation:
At the moment if you want to return a HTTP header containing multiple
values you have to set/add that header once with the values wanted. If
you used set/add with an array/iterable multiple HTTP header fields will
be returned in the response.

Note, that this is indeed a suggestion and additional work and tests
should be added. This is mainly to bring up a discussion.

Modifications:
Added a flag to specify that when multiple values exist for a single
HTTP header then add them as a comma separated string.
In addition added a method to StringUtil to help escape comma separated
value charsequences.

Result:
Allows for responses to be smaller.

afa9e71ed3 Allow to use WebSocketClientHandshaker and WebSocketServerHandshaker with HttpResponse / HttpRequest
Motivation:

To use WebSocketClientHandshaker / WebSocketServerHandshaker it's currently a requirement of having a HttpObjectAggregator in the ChannelPipeline. This is not a big deal when a user only wants to server WebSockets but is a limitation if the server serves WebSockets and normal HTTP traffic.

Modifications:

Allow to use WebSocketClientHandshaker and WebSocketServerHandshaker without HttpObjectAggregator in the ChannelPipeline.

Result:

More flexibility

b19a12b952 Fixes #3362 (Possible wrong behavior in HttpResponseDecoder/HttpRequestDecoder for large header/initline/content)
Motivation:

`HttpResponseDecoder` and `HttpRequestDecoder` in the event when the max configured sizes for HTTP initial line, headers or content is breached, sends a `DefaultHttpResponse` and `DefaultHttpRequest` respectively. After this `HttpObjectDecoder` gets into `BAD_MESSAGE` state and ignores any other data received on this connection.
The combination of the above two behaviors, means that the decoded response/request are not complete (absence of sending `LastHTTPContent`). So, any code, waiting for a complete message will have to additionally check for decoder result to follow the correct semantics of HTTP.

If `HttpResponseDecoder` and `HttpRequestDecoder` creates a Full* invalid message then the request/response is a complete HTTP message and hence obeys the HTTP contract.

Modification:

Modified `HttpRequestDecoder`, `HttpResponseDecoder`, `RtspRequestDecoder` and  `RtspResponseDecoder` to return Full* messages from `createInvalidMessage()`

Result:

Fixes the wrong behavior of sending incomplete messages from these codecs

3c6cbd40e2 Fix an sporadic failure in ServerCookieEncoderTest
In testEncodingSingleCookieV0():

Let's assume we encoded a cookie with MaxAge=50 when currentTimeMillis
is 10999.

Because the encoder will not encode the millisecond part for Expires,
the timeMillis value of the encoded Expires field will be 60000. (If we
did not dropped the millisecond part, it would be 60999.)

Encoding a cookie will take some time, so currentTimeMillis will
increase slightly, such as to 11001.

  diff = (60000 - 11001) / 1000 = 48999 / 1000 = 48
  maxAge - diff = 50 - 48 = 2

Due to losing millisecond part twice, we end up with the precision
problem illustrated above, and thus we should increase the tolerance
from 1 second to 2 seconds.

2d24e1f27d Back port HTTP/2 codec from master to 4.1
Motivation:

HTTP/2 codec was implemented in master branch.
Since, master is not yet stable and will be some time before it gets released, backporting it to 4.1, enables people to use the codec with a stable netty version.

Modification:

The code has been copied from master branch as is, with minor modifications to suit the `ChannelHandler` API in 4.x.
Apart from that change, there are two backward incompatible API changes included, namely,

- Added an abstract method:

  `public abstract Map.Entry<CharSequence, CharSequence> forEachEntry(EntryVisitor<CharSequence> visitor)
            throws Exception;`

to `HttpHeaders` and implemented the same in `DefaultHttpHeaders` as a delegate to the internal `TextHeader` instance.

- Added a method:

`FullHttpMessage copy(ByteBuf newContent);`

in `FullHttpMessage` with the implementations copied from relevant places in the master branch.

- Added missing abstract method related to setting/adding short values to `HttpHeaders`

Result:

HTTP/2 codec can be used with netty 4.1

ed10513238 Fixed several issues with HttpContentDecoder
Motivation:

HttpContentDecoder had the following issues:
- For chunked content, the decoder set invalid "Content-Length" header
	with length of the first decoded chunk.
- Decoding of FullHttpRequests put both the original conent and decoded
	content into output. As result, using HttpObjectAggregator before the
	decoder lead to errors.
- Requests with "Expect: 100-continue" header were not acknowleged:
	the decoder didn't pass the header message down the handler's chain
	until content is received. If client expected "100 Continue" response,
	deadlock happened.

Modification:

- Invalid "Content-Length" header is removed; handlers down the chain can either
	rely on LastHttpContent message or ask HttpObjectAggregator to add the header.
- FullHttpRequest is split into HttpRequest and HttpContent (decoded) parts.
- Header (HttpRequest) part of request is sent down the chain as soon as it's received.

Result:

The issues are fixed, unittest is added.

c298230128 RFC6265 cookies support
Motivation:

Currently Netty supports a weird implementation of RFC 2965.
First, this RFC has been deprecated by RFC 6265 and nobody on the
internet use this format.

Then, there's a confusion between client side and server side encoding
and decoding.

Typically, clients should only send name=value pairs.

This PR introduces RFC 6265 support, but keeps on supporting RFC 2965 in
the sense that old unused fields are simply ignored, and Cookie fields
won't be populated. Deprecated fields are comment, commentUrl, version,
discard and ports.

It also provides a mechanism for safe server-client-server roundtrip, as
User-Agents are not supposed to interpret cookie values but return them
as-is (e.g. if Set-Cookie contained a quoted value, it should be sent
back in the Cookie header in quoted form too).

Also, there are performance gains to be obtained by not allocating the
attribute name Strings, as we only want to match them to find which POJO
field to populate.

Modifications:

- New RFC6265ClientCookieEncoder/Decoder and
  RFC6265ServerCookieEncoder/Decoder pairs that live alongside old
  CookieEncoder/Decoder pair to not break backward compatibility.
- New Cookie.rawValue field, used for lossless server-client-server
  roundtrip.

Result:

RFC 6265 support.
Clean separation of client and server side.

Decoder performance gain:

04dd885421 SPDY: fix support for pushed resources in SpdyHttpEncoder
Motivation:

The SpdyHttpDecoder was modified to support pushed resources that are
divided into multiple frames. The decoder accepts a pushed
SpdySynStreamFrame containing the request headers, followed by a
SpdyHeadersFrame containing the response headers.

Modifications:

This commit modifies the SpdyHttpEncoder so that it encodes pushed
resources in a format that the SpdyHttpDecoder can decode. The encoder
will accept an HttpRequest object containing the request headers,
followed by an HttpResponse object containing the response headers.

Result:

The SpdyHttpEncoder will create a SpdySynStreamFrame followed by a
SpdyHeadersFrame when sending pushed resources.

85fecba770 Fix for Issue #3308 related to slice missing retain
Motivations:
It seems that slicing a buffer and using this slice to write to CTX will
decrease the initial refCnt to 0, while the original buffer is not yet
fully used (not empty).

Modifications:
As suggested in the ticket and tested, when the currentBuffer is sliced
since it will still be used later on, the currentBuffer is retained.

Add a test case for this issue.

Result:
The currentBuffer still has its correct refCnt when reaching the last
write (not sliced) of 1 and therefore will be released correctly.
The exception does no more occur.

This fix should be applied to all branches >= 4.0.

Related: #3019

Motivation:

We have multiple (Full)HttpRequest/Response implementations and only
some of them implements toString() properly.

Modifications:

- Add the reusable string converter for HttpMessages to HttpMessageUtil
- Implement toString() of (Full)HttpRequest/Response implementations
  properly using HttpMessageUtil

Result:

Prettier string representation is returned by HttpMessage
implementations.

f0e306c2fd Allow to override how headers are encoded
Motivation:

Even if its against the HTTP RFC there are situations where it may be useful to use other chars then US_ASCII in the headers. We should allow to make it possible by allow the user to override the how headers are encoded.

Modifications:

- Add encodeHeaders(...) method and so allow to override it.

Result:

It's now possible to encode headers with other charset then US_ASCII by just extend the encoder and override the encodeHeaders(...) method.

5ba4fdf3ba HttpObjectAggregator only set Content-Length is not already set.
Motivation:

HEAD requests will have a Content-Length set that doesn't match the
actual length. So we only want to set Content-Length header if it isn't
already set.

Modifications:

If check around setting the Content-Length.

Result:

A HEAD request will no correctly return the specified Content-Length
instead of the body length.

9ee75126eb Motivation: Sonar points out an equals comparison, where the types compared are different and don't share any common parent http://clinker.netty.io/sonar/drilldown/issues/io.netty:netty-parent:master?severity=CRITICAL#
Modifications:
Converted AsciiString into a String by calling toString() method before comparing with equals(). Also added a unit-test to show that it works.

Result:
Major violation is gone. Code is correct.

bd6d0f3fd5 ensure getRawQuery is not null before appending
Motivation:

without this check then given a URI with path /path the resulting URL will be /path?null=

Modifications:

check that getRawQuery doesn't return null and only append if not

Result:

urls of the form /path will not have a null?= appended

9b2fede68e Fix AbstractDiskHttpData int conversion from long
Motivations:
The chunkSize might be oversized after comparison (size being > of int
capacity) if file size is bigger than an integer.

Modifications:
Change it to long.

Result:
There is no more int oversized.

Same fix for 4.1 and Master
