9ac430f16f HTTP/2 DefaultHttp2RemoteFlowController Stream writability notification broken
Motivation:
DefaultHttp2RemoteFlowController.ListenerWritabilityMonitor no longer reliably detects when a stream's writability change occurs.

Modifications:
- Ensure writiability is reliabily reported by DefaultHttp2RemoteFlowController.ListenerWritabilityMonitor
- Fix infinite loop issue (https://github.com/netty/netty/issues/4588) detected when consolidating unit tests

Result:
Reliable stream writability change notification, and 1 less infinite loop in UniformStreamByteDistributor.

c22f1aa4ac Clear selectedKeys in OioSctpChannel.doReadMessages
Motivation:
The fix for https://github.com/netty/netty/issues/3884 breaks SctpEchoTest because Selector.select will always return 0 if you do not clear last selectedKeys.

Modifications:
Clear readSelector.selectedKeys() if it is not empty.

Result:
SctpEchoTest is green again.

7c1602125a Builder to construct DomainNameMapping.
Motivation:

DomainNameMapping.add() makes DomainNameMapping look like it's safe to call add() anytime, and this is never true. It's probably better deprecate add() and introduce DomainNameMappingBuilder.

Modifications:

Made an immutable implementation of DomainNameMapping;
Added Builder for immutable DomainNameMapping;
Replaced regex pattern with String::startsWith check;
Replaced HashMap with two arrays in ImmutableDomainNameMapping;
Deprecated mutable API;
Estimation for StringBuilder initial size in ImmutableDomainNameMapping#toString()
Added StringUtil#commonSuffixOfLength
Replaced unnecessary substrings creation in DomainNameMapping#matches with regionMatches

Result:

Clients will be able to create immutable instances of DomainNameMapping with builder API.

f750d6e36c ByteBufUtil.writeUtf8 Surrogate Support
Motivation:
UTF-16 can not represent the full range of Unicode characters, and thus has the concept of Surrogate Pair (http://unicode.org/glossary/#surrogate_pair) where 2 16-bit code units can be used to represent the missing characters. ByteBufUtil.writeUtf8 is currently does not support this and is thus incomplete.

Modifications:
- Add support for surrogate pairs in ByteBufUtil.writeUtf8

Result:
ByteBufUtil.writeUtf8 now supports surrogate pairs and is correctly converting to UTF-8.

693633eeff Not use Unpooled to allocate buffers in Base64 but use a ByteBufAllocator
Motivation:

We should not use Unpooled to allocate buffers for performance reasons.

Modifications:

Allow to pass in ByteBufAllocate which is used to allocate buffers or use the allocate of the src buffer.

Result:

Better performance if the PooledByteBufAllocator is used.

63426fc3ed Prevent adding newline if Base64 buffer encoded ends directly on MAX_LINE_LENGTH
Motivation:

We need to ensure we not add a newline if the Base64 encoded buffer ends directly on the MAX_LINE_LENGTH. If we miss to do so this produce invalid data.
Because of this bug OpenSslServerContext and OpenSslClientContext may fail to load a cert.

Modifications:

- Only add NEW_LINE if we not are on the end of the dst buffer.
- Add unit test

Result:

Correct result in all cases

b62c5290ed Let SniHandler accept Mapping as well as DominaNameMapping
Related: #4470 #4473

Motivation:

A user might want to:

- implement dynamic mapping from hostname to SslContext
- server large number of domain names whose SslContext can be
  initialized lazily and destroyed when unused

Modifications:

- Let SniHandler accept Mapping<String, SslContext> as well as
  DomainNameMapping
- Make the default constructor of SslContext so that a user can create
  his or her own SslContext wrapper

Result:

904e70a4d4 HTTP/2 Weighted Fair Queue Byte Distributor
Motivation:
PriorityStreamByteDistributor uses a homegrown algorithm which distributes bytes to nodes in the priority tree. PriorityStreamByteDistributor has no concept of goodput which may result in poor utilization of network resources. PriorityStreamByteDistributor also has performance issues related to the tree traversal approach and number of nodes that must be visited. There also exists some more proven algorithms from the resource scheduling domain which PriorityStreamByteDistributor does not employ.

Modifications:
- Introduce a new ByteDistributor which uses elements from weighted fair queue schedulers

Result:
StreamByteDistributor which is sensitive to priority and uses a more familiar distribution concept.

8d4db050f3 Have hosts file support for DnsNameResolver, close #4074
Motivation:

On contrary to `DefaultNameResolver`, `DnsNameResolver` doesn't currently honor hosts file.

Modifications:

* Introduce `HostsFileParser` that parses `/etc/hosts` or `C:\Windows\system32\drivers\etc\hosts` depending on the platform
* Introduce `HostsFileEntriesResolver` that uses the former to resolve host names
* Make `DnsNameResolver` check his `HostsFileEntriesResolver` prior to trying to resolve names against the DNS server
* Introduce `DnsNameResolverBuilder` so we now have a builder for `DnsNameResolver`s
* Additionally introduce a `CompositeNameResolver` that takes several `NameResolver`s and tries to resolve names by delegating sequentially
* Change `DnsNameResolver.asAddressResolver` to return a composite and honor hosts file

Result:

Hosts file support when using `DnsNameResolver`.
Consistent behavior with JDK implementation.

4e467f5c6f Throw ReadOnlyBufferException if unsafe buffer is used and dst is direct
Motivation:

We missed to check if the dst is ready only before using unsafe to copy data into it which lead to data-corruption. We need to ensure we respect ready only ByteBuffer.

Modifications:

- Correctly check if the dst is ready only before copy data into it in UnsafeByteBufUtil
- Also make it work for buffers that are not direct and not have an array

Result:

No more data corruption possible if the dst buffer is readonly and unsafe buffer implementation is used.

dd9fc289fd Throw exception if KeyManagerFactory is used with OpenSslServerContext
Motivation:

We currently not supported using KeyManagerFactory with OpenSslServerContext and so should throw an exception if the user tries to do so. This will at least not give suprising and hard to debug problems later.

Modifications:

Throw exception if a user tries to construct a OpenSslServerContext with a KeyManagerFactory

Result:

Fail fast if the user tries to use something that is not supported.

2202e8f967 Revamp the Http2ConnectionHandler builder API
Related: #4572

Motivation:

- A user might want to extend Http2ConnectionHandler and define his/her
  own static inner Builder class that extends
  Http2ConnectionHandler.BuilderBase. This introduces potential
  confusion because there's already Http2ConnectionHandler.Builder. Your
  IDE will warn about this name duplication as well.
- BuilderBase exposes all setters with public modifier. A user's Builder
  might not want to expose them to enforce it to certain configuration.
  There's no way to hide them because it's public already and they are
  final.
- BuilderBase.build(Http2ConnectionDecoder, Http2ConnectionEncoder)
  ignores most properties exposed by BuilderBase, such as
  validateHeaders, frameLogger and encoderEnforceMaxConcurrentStreams.
  If any build() method ignores the properties exposed by the builder,
  there's something wrong.
- A user's Builder that extends BuilderBase might want to require more
  parameters in build(). There's no way to do that cleanly because
  build() is public and final already.

Modifications:

- Make BuilderBase and Builder top-level so that there's no duplicate
  name issue anymore.
  - Add AbstractHttp2ConnectionHandlerBuilder
  - Add Http2ConnectionHandlerBuilder
  - Add HttpToHttp2ConnectionHandlerBuilder
- Make all builder methods in AbstractHttp2ConnectionHandlerBuilder
  protected so that a subclass can choose which methods to expose
- Provide only a single build() method
  - Add connection() and codec() so that a user can still specify
    Http2Connection or Http2Connection(En|De)coder explicitly
  - Implement proper state validation mechanism so that it is prevented
    to invoke conflicting setters

Result:

Less confusing yet flexible builder API

253cd694ef Ensure we not leave data in the BIO when error happens.
Motivation:

We need to ensure we consume all pending data in the BIO on error to correctly send the close notify for the remote peer.

Modifications:

Correctly force the user to call wrap(...) if there is something left in the BIO.

Result:

close_notify is not lost.

eb577c5bd9 Respect ClientAuth set via OpenSslEngine constructor
Motivation:

When ClientAuth is set via SslContextBuilder we pass it into the OpenSslEngine constructor. Due a bug we missed to call the correct native methods and so never enabled ClientAuth in this case.

Modifications:

Correctly call setClientAuth(...) in the constructor if needed.

Result:

client auth also works when configured via the SslContextBuilder and OPENSSL is used.

27b330d8b1 Moving KObjectHashMapTest to propert directory
Motivation:

6393506b97 Extract SocketAdress logic from NameResolver
Motivation:

As discussed in #4529, NameResolver design shouldn't be resolving SocketAddresses (or String name + port) and return InetSocketAddresses. It should resolve String names and return InetAddresses.
This SocketAddress to InetSocketAddresses resolution is actually a different concern, used by Bootstrap.

Modifications:

Extract SocketAddress to InetSocketAddresses resolution concern to a new class hierarchy named AddressResolver.
These AddressResolvers delegate to NameResolvers.

Result:

Better separation of concerns.

Note that new AddressResolvers generate a bit more allocations because of the intermediate Promise and List<InetAddress>.

89ff831a67 [#4449] Remove registered events from eventloop before close
Motivation:

We need to remove all registered events for a Channel from the EventLoop before doing the actual close to ensure we not produce a cpu spin when the actual close operation is delayed or executed outside of the EventLoop.

Modifications:

e5386b05e6 Move Hex dump related util from ByteBufUtil to inner class
Motivation:

Initialisation of the ByteBufUtil class, a class frequently used is
delayed because a significant number of String operations is performed to
fill a HEXDUMP_ROWPREFIXES array. This array also sticks to the Strings
forever.
It is quite likely that applications never use the hexdump facility.

Modification:

Moved the static initialisation and references to a static inner class.
This delays initialisation (and memory usage) until actually needed.
The API is kept as is.

Result:

Faster startup time, less memory usage for most netty using applications.

1f6b957377 Ensure we retain the original hostname when connect to a remote peer when using epoll transport.
Motivation:

We should retain the original hostname when connect to a remote peer so the user can still query the origin hostname if getHostString() is used.

Modifications:

Compute a InetSocketAddress from the original remote address and the one returned by the Os.

Result:

Same behavior when using epoll transport and nio transport.

6257091d12 HttpConversionUtil does not account for COOKIE compression
Motivation:
The HTTP/2 RFC allows for COOKIE values to be split into individual header elements to get more benefit from compression (https://tools.ietf.org/html/rfc7540#section-8.1.2.5). HttpConversionUtil was not accounting for this behavior.

Modifications:
- Modify HttpConversionUtil to support compressing and decompressing the COOKIE values

Result:
HttpConversionUtil is compatible with https://tools.ietf.org/html/rfc7540#section-8.1.2.5)

2fefb2f79c Make DnsNameResolverGroup non-final and overridable
Motivation:

There's no way to override the default settings of the DnsNameResolvers
created by DnsNameResolverGroup because DnsNameResolverGroup is final.

Modifications:

- Make DnsNameResolverGroup non-final
- Add a new overridable protected method 'newResolver()' so that a user
  can override it to create an alternative DnsNameResolver instance or
  set the non-default properties

Result:

A user can configure the DnsNameResolver.

a3bdd8c948 Don't cycle DNS servers while cycling DNS record types.
Motivation:

Each server should be checked for every record type. Currently, if there
are only two configured servers and the first is down, it is impossible
to query for IPv4 addresses because the second server is only ever
queried for type AAAA.

Modifications:

Do not cycle DNS servers while cycling DNS record types (A and AAAA)

Result:

Name resolution is less fragile when the number of available DNS servers
is 2.

43ebbc3fa0 Update JDK SSL Tests to use SSL Context Builder.
Motivation:

Use new / non-deprecated APIs for creating SSL Context
in tests, in order to be able to implement OpenSsl
tests with maximum code reuse.

Modifications:

Use `SslContextBuilder.(forServer|forClient)` instead
of deprecated `JdkSslServerContext` constructor.
Use `ApplicationProtocolConfig` instead of Protocol
Negotiator.
Use custom exception type for skipping tests to avoid
swallowing exceptions arising from tests.

Result:

Exceptions from tests aren't swallowed.
Using new APIs allows reusing same test code for
OpenSsl tests.

c1f3200c87 Fix the incorrect usage/value of 'Connection: upgrade'
Motivation:

HttpClientUpgradeHandler uses HttpHeaderNames.UPGRADE as the value of
the 'Connection' header, which is incorrect. It should use
HttpHeaderValues.UPGRADE instead (note Names vs Values.)

Also, HttpHeaderValues.UPGRADE should be 'upgrade' rather than
'Upgrade', as defined in:

- https://tools.ietf.org/html/rfc7230#section-6.7

Modifications:

- Use HttpHeaderValues.UPGRADE for a 'Connection' header
- Lowercase the value of HttpHeaderValues.UPGRADE

9dd68d0c3e Fix IllegalReferenceCountException caused by HttpClientCodec.upgradeFrom()
Motivation:

On a successful protocol upgrade in HTTP, HttpClientUpgradeHandler calls
HttpClientCodec.upgradeFrom(), which removed both the HTTP encoder and
decoder from the pipeline immediately.

However, because the decoder is in the middle of the decode loop,
removing it from the pipeline immediately will cause the cumulation
buffer to be released prematurely.

This often leads to an IllegalReferenceCountException or missing first
response after the upgrade response.

Modifications:

- Remove the decoder *after* the decode loop is done

Result:

Fixes #4504

ef3a9b0acd Relax the sanity check in HttpClientUpgradeHandler
Motivation:

HttpClientUpgradeHandler currently throws an IllegalStateException when
the server sends a '101 Switching Protocols' response that has no
'Upgrade' header.

Some servers do not send the 'Upgrade' header on a successful protocol
upgrade and we could safely assume that the server accepted the
requested protocol upgrade in such a case, looking from the response
status code (101)

Modifications:

- Do not throw an IllegalStateException when the server responded 101
  without a 'Upgrade' header
- Note that we still check the equality of the 'Upgrade' header when it
  is present.

Result:

- Fixes #4523
- Better interoperability

0ec34b5f76 Fix race-condition when closing a NioSocketChannel or EpollSocketChannel
Motivation:

Fix a race-condition when closing NioSocketChannel or EpollSocketChannel while try to detect if a close executor should be used and the underlying socket was already closed. This could lead to an exception that then leave the channel / in an invalid state and so could lead to side-effects like heavy CPU usage.

Modifications:

Catch possible socket exception while try to get the SO_LINGER options from the underlying socket.

Result:

No more race-condition when closing the channel is possible with bad side-effects.

4978266d52 Make cookie encoding conform better to RFC 6265 in STRICT mode.
Motivation:

- On the client, cookies should be sorted in decreasing order of path
  length. From RFC 6265:

      5.4.2. The user agent SHOULD sort the cookie-list in the following
      order:

        *  Cookies with longer paths are listed before cookies with
           shorter paths.

        *  Among cookies that have equal-length path fields, cookies with
           earlier creation-times are listed before cookies with later
           creation-times.

      NOTE: Not all user agents sort the cookie-list in this order, but
      this order reflects common practice when this document was
      written, and, historically, there have been servers that
      (erroneously) depended on this order.

  Note that the RFC does not define the path length of cookies without a
  path. We sort pathless cookies before cookies with the longest path,
  since pathless cookies inherit the request path (and setting a path
  that is longer than the request path is of limited use, since it cannot
  be read from the context in which it is written).

- On the server, if there are multiple cookies of the same name, only one
  of them should be encoded. RFC 6265 says:

      Servers SHOULD NOT include more than one Set-Cookie header field in
      the same response with the same cookie-name.

  Note that the RFC does not define which cookie should be set in the case
  of multiple cookies with the same name; we arbitrarily pick the last one.

Modifications:

- Changed the visibility of the 'strict' field to 'protected' in
  CookieEncoder.

- Modified ClientCookieEncoder to sort cookies in decreasing order of path
  length when in strict mode.

- Modified ServerCookieEncoder to return only the last cookie of a given
  name when in strict mode.

- Added a fast path for both strict mode in both client and server code
  for cases with only one cookie, in order avoid the overhead of sorting
  and memory allocation.

- Added unit tests for the new cases.

Result:

- Cookie generation on client and server is now more conformant to RFC 6265.

641505a5d2 DefaultChannelConfig maxMessagesPerRead default not always set
Motivation:
ChannelMetadata has a field minMaxMessagesPerRead which can be confusing. There are also some cases where static instances are used and the default value for channel type is not being applied.

Modifications:
- use a default value which is set unconditionally to simplify
- make sure static instances of MaxMessagesRecvByteBufAllocator are not used if the intention is that the default maxMessagesPerRead should be derived from the channel type.

Result:
Less confusing interfaces in ChannelMetadata and ChannelConfig. Default maxMessagesPerRead is correctly applied.

8cd259896e No HTTP/2 RST_STREAM if no prior HEADERS were sent
Motivation:

Because we flow control HEADERS frames, it's possible that an intermediate error can result in a RST_STREAM frame being sent for a frame that the other endpoint is not yet aware of. This is a violation of the spec and will either result in spammy logs at the other endpoint or broken connections.

Modifications:

Modified the HTTP/2 handler so that it only sends RST_STREAM if it has sent at least one HEADERS frame to the remote endpoint for the stream.

Result:

Fixes #4465
