45849b2fa8 Deprecate PromiseAggregator
Motivation:
PromiseAggregator's API allows for the aggregate promise to complete before the user is done adding promises. In order to support this use case the API structure would need to change in a breaking manner.

Modifications:
- Deprecate PromiseAggregator and subclasses
- Introduce PromiseCombiner which corrects these issues

Result:
PromiseCombiner corrects the deficiencies in PromiseAggregator.

97df3cb039 [#4936] NetUtil can prevent using Netty due to SecurityManager denial
Motivation:

A custom SecurityManager may prevent calling File.exists() and so throw a SecurityException in the static init block of NetUtil.

Modifications:

Correctly catch the exception and so allow to static init NetUtil.

Result:

Allow static init method of NetUtil to work even with custom SecurityManager.

050ac709ba PromiseNotifier does not propagate cancel events
Motivation:
If the Future that the PromiseNotifier is listening to is cancelled, it does not propagate the cancel to all the promises it is expected to notify.

Modifications:
- If the future is cancelled then all the promises should be cancelled
- Add a UnaryPromiseNotifier if a collection of promises is not necessary

Result:
PromiseNotifier propagates cancel events to all promises

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.

fdc6a5e87f Leak Detector disclosing when records dropped
Motivation:
ResourceLeakDetector enforces a limit as to how large the queue is allowed to grow for stack traces in order to keep memory from growing too large. However it is not always clear when records are dropped, or how many have been dropped. This can make interpreting leak reports more difficult if you assume all information is present when it may not be. Also we should increase the limit (currently 4) when running tests on the CI servers.

Modifications:
- Increase leak detector record limit on CI servers from 4 to 32.
- Track how many records have been discarded and disclose this in the leak report.

Result:
Leak reports clarify how many records were dropped, and how to increase the limit.

a51e2c8769 Expose Helper to obtain the "best" mac address.
Motivation:

The implementation of obtaining the best possible mac address is very good. There are many sub-par implementations proposed on stackoverflow.
While not strictly a netty concern, it would be nice to offer this util also to netty users.

Modifications:

extract DefaultChannelId#defaultMachineId code obtaining the "best" mac into a new helper called MacAddress, keep the random bytes fallback in DefaultChannelID.

Result:

New helper available.

b7415a3307 Add a reusable ArrayList to InternalThreadLocalMap
Motivation:

See #3411. A reusable ArrayList in InternalThreadLocalMap can avoid allocations in the following pattern:

```
List<...> list = new ArrayList<...>();

add something to list but never use InternalThreadLocalMap

return list.toArray(new ...[list.size()]);

```

Modifications:

Add a reusable ArrayList to InternalThreadLocalMap and update codes to use it.

Result:

Reuse a thread local ArrayList to avoid allocations.

ca305d86fb PlatformDependent String char[] optimization
Motivation:
PlatformDependent0 has an optimization which grabs the char[] from a String. Since this code was introduced http://openjdk.java.net/jeps/254 has been gaining momentum in JDK 9. This JEP changes the internal storage from char[] to byte[], and thus the existing char[] only based optimizations will not work.

Modifications:
- The ASCII encoding char[] String optimizations should also work for byte[].

Result:
ASCII encoding char[] String optimizations don't break if the underlying storage in String is byte[].

7494e84208 PlatformDependent static initialization ExceptionInInitializerError
Motivation:
PlatformDependent allows some exceptions to escape during static initialization. If an exception escapes it will be translated into a java.lang.ExceptionInInitializerError and render the application unable to run.

Modifications:
- Make sure to catch Throwable during static initialization.

Result:
PlatformDependent static initialization doesn't result in java.lang.ExceptionInInitializerError.

7dba13f276 HttpConversionUtil remove throws from method signature
Motivation:
HttpConversionUtil.toHttp2Headers currently has a throws Exception as part of the signature. This comes from the signature of ByteProcessor.process, but is not necessary because the ByteProcessor used does not throw.

Modifications:
- Remove throws Exception from the signature of HttpConversionUtil.toHttp2Headers.

Result:
HttpConversionUtil.toHttp2Headers interface does not propagate a throws Exception when it is used.

b4be040f30 Introduce DnsCache API + DnsResolver extensibility
Motivation:
Caching is currently nested in DnsResolver.
It should also be possible to extend DnsResolver to ba able to pass a different cache on each resolution attemp.

Modifications:

* Introduce DnsCache, NoopDnsCache and DefaultDnsCache. The latter contains all the current caching logic that was extracted.
* Introduce protected versions of doResolve and doResolveAll that can be used as extension points to build resolvers that bypass the main cache and use a different one on each resolution.

Result:

Isolated caching logic. Better extensibility.

1bee71fb1c Fix PlatformDependent.newAtomic*FieldUpdater type safety
Motivation:

* newAtomicIntegerFieldUpdater and newAtomicLongFieldUpdater take a
class<?> so they're too lax
* newAtomicReferenceFieldUpdater takes a Class<U> so it's too strict
and can only be passe a rawtype parameter when dealing w/ generic
classes

Modifications:

Take a Class<? super T> parameter instead.

Result:

Better type safety and generics support.

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.

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.

27b330d8b1 Moving KObjectHashMapTest to propert directory
Motivation:

The KObjectHashMapTest is in a directory called "io.netty.util.collection" rather than "io/netty/util/collection". This causes the generated tests to be created in the wrong directory as well.

Modifications:

Moved the file.

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)

1f3fc983c0 DefaultPromise LateListener notification order
Motivation:
There is a notification ordering issue in DefaultPromise when the lateListener collection is in use. The ordering issue can be observed in situations where a late listener is added to a Future returned from a write operation. It is possible that this future will run after a read operation scheduled on the I/O thread, even if the late listener is added on the I/O thread. This can lead to unexpected ordering where a listener for a write operation which must complete in order for the read operation to happen is notified after the read operation is done.

Modifications:
- If the lateListener collection becomes empty, it should be treated as though it was null when checking if lateListeners can be notified immediatley (instead of executing a task on the executor)

Result:
Ordering is more natural and will not be perceived as being out of order relative to other tasks on the same executor.

2a65ae256e [#4331] Helper methods to get charset from Content-Type header of HttpMessage
Motivation:

HttpHeaders already has specific methods for such popular and simple headers like "Host", but if I need to convert POST raw body to string I need to parse complex ContentType header in my code.

Modifications:

Add getCharset and getCharsetAsString methods to parse charset from Content-Length header.

Result:

Easy to use utility method.

19658e9cd8 HTTP/2 Headers Type Updates
Motivation:
The HTTP/2 RFC (https://tools.ietf.org/html/rfc7540#section-8.1.2) indicates that header names consist of ASCII characters. We currently use ByteString to represent HTTP/2 header names. The HTTP/2 RFC (https://tools.ietf.org/html/rfc7540#section-10.3) also eludes to header values inheriting the same validity characteristics as HTTP/1.x. Using AsciiString for the value type of HTTP/2 headers would allow for re-use of predefined HTTP/1.x values, and make comparisons more intuitive. The Headers<T> interface could also be expanded to allow for easier use of header types which do not have the same Key and Value type.

Motivation:
- Change Headers<T> to Headers<K, V>
- Change Http2Headers<ByteString> to Http2Headers<CharSequence, CharSequence>
- Remove ByteString. Having AsciiString extend ByteString complicates equality comparisons when the hash code algorithm is no longer shared.

Result:
Http2Header types are more representative of the HTTP/2 RFC, and relationship between HTTP/2 header name/values more directly relates to HTTP/1.x header names/values.

Modifications:

- Add PooledUnsafeHeapByteBuf and UnpooledUnsafeHeapByteBuf that are used when sun.misc.Unsafe is ready to use.
- Add UnsafeHeapSwappedByteBuf

Result:

Better performance when using heap buffers and sun.misc.Unsafe is ready to use.
