81f9de423c HostsFileParser should allow both IPv4 and IPv6 for a given host
Motivation:

HostsFileParser only retains the first address for each given hostname.
This is wrong, and it’s allowed to have both an IPv4 and an IPv6.

Modifications:

* Have `HostsFileParser` now return a `HostsFileEntries` that contains IPv4 entries and IPv6 entries
* Introduce `ResolvedAddressTypes` to describe resolved address types preferences
* Add a new `ResolvedAddressTypes` parameter to `HostsFileEntriesResolver::address` to account for address types preferences
* Change `DnsNameResolver` constructor to take a `ResolvedAddressTypes`, allowing for a null value that would use default
* Change `DnsNameResolverBuilder::resolvedAddressTypes` to take a `ResolvedAddressTypes`
* Make `DnsNameResolver::resolvedAddressTypes` return a `ResolvedAddressTypes`
* Add a static `DnsNameResolverBuilder::computeResolvedAddressTypes` to ease converting from `InternetProtocolFamily`

Result:

We now support hosts files that contains IPv4 and IPv6 pairs for a same
hostname.

64abef5f5b Add exposeHeaders and allowedRequestHeaders that accept CharSequence, close #6328
Motivation:

Netty 4.1 introduced AsciiString and defines HttpHeaderNames constants
as such.

It would be convenient to be able to pass them to `exposeHeaders` and
`allowedRequestHeaders` directly without having to call `toString`.

Modifications:

Add `exposeHeaders` and `allowedRequestHeaders` overloads that take a
`CharSequence`.

Result:

More convenient API

64838f1505 Cleanup : validatePromise ranamed to isNotValidPromise and added more tests for corner cases.
Motivation:

Result of validatePromise() is always inverted with if (!validatePromise()).

Modification:

validatePromise() renamed to isNotValidPromise() and now returns inverted state so you don't need to invert state in conditions. Also name is now more meaningful according to returned result.
Added more tests for validatePromise corner cases with Exceptions.

Result:

Code easier to read. No need in inverted result.

d06990f434 OpenSSL ByteBuffer BIO
Motivation:
Currently Netty utilizes BIO_new_bio_pair so we can control all FD lifetime and event notification but delegates to OpenSSL for encryption/decryption. The current implementation sets up a pair of BIO buffers to read/write encrypted/plaintext data. This approach requires copying of data from Java ByteBuffers to native memory BIO buffers, and also requires both BIO buffers to be sufficiently large to hold application data. If direct ByteBuffers are used we can avoid coyping to/from the intermediate BIO buffer and just read/write directly from the direct ByteBuffer memory. We still need an internal buffer because OpenSSL may generate write data as a result of read calls (e.g. handshake, alerts, renegotiation, etc..), but this buffer doesn't have to be be large enough to hold application data.

Modifications:
- Take advantage of the new ByteBuffer based BIO provided by netty-tcnative instead of using BIO_read and BIO_write.

Result:
Less copying and lower memory footprint requirement per TLS connection.

007048dddd DnsNameResolver empty/null hostname missed by a416b79
Motivation:
a416b79 introduced a check for null or empty host name to be compatible with the JDK resolution. However the doResolve(String, Promise) method, and if the doResolve(String, DnsRecord[], Promise, DnsCache) method was overridden the empty/null hostname would not be correctly resolved.

Modifications:
- Move the empty/null host name check into the lowest level doResolve method in DnsNameResolver
- Remove the duplicate logic in InetNameResolver.java which can be bypassed anyways

Result:
By default (unless behavior is overridden) DnsNameResolver resolves null/empty host names to local host just like the JDK.

9d45f514a4 Add a constant for Cookie "undefined maxAge"
Motivation:

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.

3462a86a3a Ensure we release the previous retained AddressedEnvelope when we fail to notify the promise.
Motivation:

We need to ensure we release the AddressedEnvelope if we fail to notify the future (as it may be notified before because of an timeout). Otherwise we may leak.

Modifications:

Call release() if we fail to notify the future.

Result:

No more memory leak on notify failure.

14b902fced Deprecate and ignore ResourceLeakDetector's maxActive parameter
Motivation:
ResourceLeakDetector supports a parameter called maxActive. This parameter is used in attempt to limit the amount of objects which are being tracked for leaks at any given time, and generates an error log message if this limit is exceeded. This assumes that there is a relationship between leak sample rate and object lifetime for objects which are already being tracked. This relationship may appear to work in cases were there are a single leak record per object and those leak records live for the lifetime of the application but in general this relationship doesn't exist. The original motivation was to provide a limit for cases such as HashedWheelTimer to limit the number of instances which exist at any given time. This limit is not enforced in all circumstances in HashedWheelTimer (e.g. if the thread is a daemon) and can be implemented outside ResourceLeakDetector.

Modifications:
- Deprecate all methods which interact with maxActive in ResourceLeakDetectorFactory and ResourceLeakDetector
- Remove all logic related to maxActive in ResourceLeakDetector
- HashedWheelTimer implements its own logic to impose a limit and warn users if too many instances exists at any given time.

Result:
Fixes https://github.com/netty/netty/issues/6225.

6353c229fd SslHandler avoid calling wrap/unwrap when unnecessary
Motivation:
The SSLEngine wrap and unwrap methods can be called in a way that has no side effects, but this could involve costly validation and allocation. The SslHandler should avoid calling into these methods if possible.

Modifications:
- wrapNonAppData should provide additional status which can be used by wrap to breakout early if possible

Result:
SslHandler invokes the SSLEngine less.

72916b9960 Add unit test on DefaultHttp2FrameReader
Motivation:

DefaultHttp2FrameReader contains the logic for how it parsed the network
traffic from http2 client,
it also validate the content is legal or not.
So keep high coverage rate on it will increase the stability of api.

Modifications:

Add unit test on DefaultHttp2FrameReader

42c0359820 Do not prefer empty MAC address
Motivation:

When comparing MAC addresses searching for the best MAC address, if
locally-administered address (e.g., from a Docker container) is compared
against an empty MAC address, the empty MAC address will be marked as
preferred. In cases this is the only available MAC address, this leaves
Netty using a random machine ID instead of using a perfectly valid
machine ID from the locally-adminstered address.

Modifications:

This commit modifies the MAC address logic so that the empty MAC address
is not preferred over a locally-administered address. This commit also
simplifies the comparison logic here.

Result:

Empty MAC addresses will not be preferred over locally-administered
addresses thus permitting the default machine ID to be the
locally-adminstered MAC address if it is the only available MAC address.

661ff2538e Implement correct handling of recursive DNS
Motivation:

DnsNameResolver does not handle recursive DNS and so fails if you query a DNS server (for example a ROOT dns server) which provides the correct redirect for a domain.

Modification:

Add support for redirects (a.k.a. handling of AUTHORITY section').

Result:

Its now possible to use a DNS server that redirects.

8a5e42ad2e Correct fail write with NotYetConnectedException when OioDatagramChannel is not connected yet.
Motivation:

NioDatagramChannel fails a write with NotYetConnectedException when the DatagramChannel was not yet connected and a ByteBuf is written. The same should be done for OioDatagramChannel as well.

Modifications:

Make OioDatagramChannel consistent with NioDatagramChannel

Result:

Correct and consistent implementations of DatagramChannel

66b9be3a46 Allow to allign allocated Buffers
Motivation:

64-byte alignment is recommended by the Intel performance guide (https://software.intel.com/en-us/articles/practical-intel-avx-optimization-on-2nd-generation-intel-core-processors) for data-structures over 64 bytes.
Requiring padding to a multiple of 64 bytes allows for using SIMD instructions consistently in loops without additional conditional checks. This should allow for simpler and more efficient code.

Modification:

At the moment cache alignment must be setup manually. But probably it might be taken from the system. The original code was introduced by @normanmaurer https://github.com/netty/netty/pull/4726/files

Result:

Buffer alignment works better than miss-align cache.

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.

1d128c7a65 Switch to netty-tcnative 2.0.0 which uses different package names
Motivation:

Previous versions of netty-tcnative used the org.apache.tomcat namespace which could lead to problems when a user tried to use tomcat and netty in the same app.

Modifications:

Use netty-tcnative which now uses a different namespace and adjust code to some API changes.

Result:

Its now possible to use netty-tcnative even when running together with tomcat.

3482651e0c HTTP/2 Non Active Stream RFC Corrections
Motivation:
codec-http2 couples the dependency tree state with the remainder of the stream state (Http2Stream). This makes implementing constraints where stream state and dependency tree state diverge in the RFC challenging. For example the RFC recommends retaining dependency tree state after a stream transitions to closed [1]. Dependency tree state can be exchanged on streams in IDLE. In practice clients may use stream IDs for the purpose of establishing QoS classes and therefore retaining this dependency tree state can be important to client perceived performance. It is difficult to limit the total amount of state we retain when stream state and dependency tree state is combined.

Modifications:
- Remove dependency tree, priority, and weight related items from public facing Http2Connection and Http2Stream APIs. This information is optional to track and depends on the flow controller implementation.
- Move all dependency tree, priority, and weight related code from DefaultHttp2Connection to WeightedFairQueueByteDistributor. This is currently the only place which cares about priority. We can pull out the dependency tree related code in the future if it is generally useful to expose for other implementations.
- DefaultHttp2Connection should explicitly limit the number of reserved streams now that IDLE streams are no longer created.

Result:
More compliant with the HTTP/2 RFC.

6e5b25733f HTTP/2 Connection Preface User Event
Motivation:
If an HTTP/2 client writes data before the connection preface the peer will shutdown the socket. Depending on what is in the pipeline (SslHandler) may require different evaluation criteria to infer when the codec-http2 has written the connection preface on behalf of the client. This can lead to unnecessarily complexity and error prone/racy application code.

Modifications:
- Introduce a user event that is fired up the pipeline when codec-http2 writes the connection preface

Result:
Reliable mechanism for applications to use to know when connection preface has been written (related to https://github.com/netty/netty/issues/6272).

66b1731041 PooledByteBuf.capacity(...) not enforces maxCapacity()
Motivation:

PooledByteBuf.capacity(...) miss to enforce maxCapacity() and so its possible to increase the capacity of the buffer even if it will be bigger then maxCapacity().

Modifications:

- Correctly enforce maxCapacity()
- Add unit tests for capacity(...) calls.

Result:

Correctly enforce maxCapacity().

0d5b665fba Automatically decode DNS domain name to unicode
Motivation:

DnsNameResolver will return the domain / host name as ascii code using punycode (https://tools.ietf.org/html/rfc3492). This is different to what the JDK does which always convert it to unicode. We should do the same by default but allow to also not do it.

Modifications:

- Add new builder method on DnsNameResolverBuilder which allow to disable / enable converting. Default is to convert just like the JDK does.
- Add unit tests for it.

Result:

DnsNameResolver and JDK impl behave the same way.

ead9938980 Include Http 1 request in error message
Motivation:

When An HTTP server is listening in plaintext mode, it doesn't have
a chance to negotiate "h2" in the tls handshake.  HTTP 1 clients
that are not expecting an HTTP2 server will accidentally a request
that isn't an upgrade, which the HTTP/2 decoder will not
understand.  The decoder treats the bytes as hex and adds them to
the error message.

These error messages are hard to understand by humans, and result
in extra, manual work to decode.

Modification:

If the first bytes of the request are not the preface, the decoder
will now see if they are an HTTP/1 request first.  If so, the error
message will include the method and path of the original request in
the error message.

In case the path is long, the decoder will check up to the first
1024 bytes to see if it matches.  This could be a DoS vector if
tons of bad requests or other garbage come in.  A future optimization
would be to treat the first few bytes as an AsciiString and not do
any Charset decoding.  ByteBuf.toCharSequence alludes to such an
optimization.

The code has been left simple for the time being.

Result:

Faster identification of errant HTTP requests.

7736534b34 Ensure tests added in 91f050d2ef work with different openssl installations
Motivation:

Tests were added in 91f050d2ef to run with different protocols / ciphers. These may fail currently when openssl was compiled without support for the protocol / ciphers.

Modifications:

- Refactor tests to easier understand for which protocol / cipher it failed
- Not fail the test if the protocol is not supported with the used openssl version.

Result:

More robust testing.

Motivation:

A testing goof in 7c630fe introduced a binary incompatibility when the old Promise-specific `add` and `addAll` methods in PromiseCombiner were generalized to accept `Futures`.

Modification:

- Restore (but mark as `@Deprecated`) old PromiseCombiner methods.
- Fixed a couple minor documentation typos because sure why not.

Result:

`PromiseCombiner` is binary-compatible with previous versions of Netty.

91f050d2ef More precise calculate the maximum record size when using SslProvider.OPENSSL* and so decrease mem usage.
Motivation:

We used ca 2k as maximum overhead for encrypted packets which is a lot more then what is needed in reality by OpenSSL. This could lead to the need of more memory.

Modification:

- Use a lower overhead of 86 bytes as defined by the spec and openssl itself
- Fix unit test to use the correct session to calculate needed buffer size

Result:

Less memory usage.

e13da218e9 HTTP/2 revert Http2FrameWriter throws API change
Motivation:
2fd42cfc6b fixed a bug related to encoding headers but it also introduced a throws statement onto the Http2FrameWriter methods which write headers. This throws statement makes the API more verbose and is not necessary because we can communicate the failure in the ChannelFuture that is returned by these methods.

Modifications:
- Remove throws from all Http2FrameWriter methods.

Result:
Http2FrameWriter APIs do not propagate checked exceptions.

a416b79d86 DnsNameResolver.resolve*(...) never notifies the Future when empty hostname is used.
Motivation:

When an empty hostname is used in DnsNameResolver.resolve*(...) it will never notify the future / promise. The root cause is that we not correctly guard against errors of IDN.toASCII(...) which will throw an IllegalArgumentException when it can not parse its input. That said we should also handle an empty hostname the same way as the JDK does and just use "localhost" when this happens.

Modifications:

- If the try to resolve an empty hostname we use localhost
- Correctly guard against errors raised by IDN.toASCII(...) so we will always noify the future / promise
- Add unit test.

Result:

DnsNameResolver.resolve*(...) will always notify the future.

640ef615be Allow to configure SslHandler to wait for close_notify response before closing the Channel and fix racy flush close_notify timeout scheduling.
Motivation:

SslHandler closed the channel as soon as it was able to write out the close_notify message. This may not be what the user want as it may make sense to only close it after the actual response to the close_notify was received in order to guarantee a clean-shutdown of the connection in all cases.

Beside this closeNotifyFlushTimeoutMillis is volatile so may change between two reads. We need to cache it in a local variable to ensure it not change int between. Beside this we also need to check if the flush promise was complete the schedule timeout as this may happened but we were not able to cancel the timeout yet. Otherwise we will produce an missleading log message.

Modifications:

- Add new setter / getter to SslHandler which allows to specify the behavior (old behavior is preserved as default)
- Added unit test.
- Cache volatile closeNotifyTimeoutMillis.
- Correctly check if flush promise was complete before we try to forcibly close the Channel and log a warning.
- Add missing javadocs.

Result:

More clean shutdown of connection possible when using SSL and fix racy way of schedule close_notify flush timeouts and javadocs.

e9fa40d770 Ensure calling ReferenceCountedOpenSslEngine.wrap(...) after closeOutbound() was called will not throw an SSLException
Motivation:

PR [#6238] added guards to be able to call wrap(...) / unwrap(...) after the engine was shutdown. Unfortunally one case was missed which is when closeOutbound() was called and produced some data while closeInbound() was not called yet.
