Subject: [PATCH 001/824] Ignoring `ClosedChannelException` from the error
 stream. (#105)

Problem

Since `ReactiveSocket` reads and writes from a transport connection, it is completely expected that at some point the underlying connection may have been severed. In such a case, both the read and write will fail on the connection. This pollutes logs of applications that directly log the error stream (as expected).

Modification

Since, this is kind of an "expected" exception, there is no point to send this to the error stream.
This change adds a filter to the error stream to filter any known exceptions (as of today, it is only `ClosedChannelException`)

PS: We currently do not unsubscribe from the input (and stop writing) when `ReactiveSocket` is explicitly closed. This change does not mean, we do not clean that up.

Subject: [PATCH 002/824] Add an overload of `TcpReactiveSocketServer.create`
 with SocketAddress. (#108)

**Problem**
It is impossible to specify the network interface to use when starting a server.
This can be problematic when we want to design test that run in restricted
environment (e.g. CI).

**Solution**
Create an overload of `TcpReactiveSocketServer.create` that accept a
SocketAddress instead of just the port.

Subject: [PATCH 003/824] Fix subscription for Websocket transport (#109)

**Problem**
The websocket DuplexConnection doesn't initialize the Publisher chain
in every cases.

**Solution**
Move the initialization code `onSubscribe` up, and also rename the subscriber
`subscriber` instead of `s` to avoid confusion with the `Subscription`.

Subject: [PATCH 004/824] Unsubscribe from the connection before `shutdown` the
 RS. (#107)

* Unsubscribe from the connection before `shutdown` the RS.

**Problem**
When we close a ReactiveSocket, it closes the underlying DuplexConnection
which trigger an unnecessary onError on the Requester/Responder.

**Solution**
Store the disposable of the DuplexConnection subscription as an instance
variable, and dispose it before closing the DuplexConnection.

**Modification**
I also added a `name` method in Requester/Responder to simplify debugging
code where we have client and server in the same JVM.
It now shows which Requester/Responder is generating an error, the client's
one or the server's one.

#### Solution

Gimme back my spaces.

#### Result

Awesomeness .....

PS: I don't use vim or emacs... Idea rocks!

Subject: [PATCH 006/824] Completing subscriber after sending error frame
 (caused memory leak). (#115)

* Completing subscriber after sending error frame (caused memory leak).

#### Problem

In some cases, `Responder` was converting an `onError()` to `onNext(Frame.Error)` but was not sending an `onComplete()` after the `onNext()`.
This causes the `subscriber` to wait for a terminal event, which never arrives, or if it arrives, does not find the `streamId` to be valid since the code was invoking `cleanUp()`.
This although subtle, but causes memory build up as the `Subscriber` in the case of a server, is the subscriber which is writing the response. If the response does not complete, all state associated with the request is kept alive forever.

#### Solution

Call `onComplete()` after sending an error frame.

This code does not call `cancel()` after `onComplete()` as reactive streams spec does not mandate cancellation post a terminal event, unlike `RxJava`.

#### Result

No more memory leak!

Subject: [PATCH 007/824] Add encrypted keys for Sonatype/Bintray (#116)

***Problem***
The Maven Central synchronization is not working (Travis CI is building the jars, but can't copy them to maven central).

***Solution***
This is the result of removing the previously encrypted keys, and running this script (authenticated as ReactiveSocketAdmin).

```
travis encrypt bintrayUser=*** --add
travis encrypt bintrayKey=*** --add
travis encrypt sonatypeUsername=*** --add
travis encrypt sonatypePassword=*** --add
```

Subject: [PATCH 009/824] Statically create `TimeoutException`. (#117)

* Statically create `TimeoutException`.

#### Problem

If a host is latent and most of the requests happen to timeout, creating a new `TimeoutException` for every timeout produces garbage and wastes CPU fetching the stack, which is useless.

#### Solution

Create a static instance of `TimeoutException` and fill it with empty stack.

#### Result

Less garbage, less work, more happiness.

* Review comments.

Subject: [PATCH 010/824] Loadbalancer: Refactor socket/factory Map into Lists
 + bugfix. (#112)

* Loadbalancer: Refactor socket/factory Map into Queues + bugfix.

**Problem**
The loadbalancer uses internally 2 maps, one for the list of `ReactiveSocketFactory`
it can use for creating a new `ReactiveSocket`, and one for the active `ReactiveSocket`.
The link is made between the 2 maps through the `SocketAddress` of the associated
remote server. This is kind of clunky and requires explicit knowledge of
the `SocketAddress` (result type of `remote()`).

Also, when we select a new factory to connect to or when we select the slowest
ReactiveSocket to quick out, the sorting is made via the `sorted()` method
on the java stream. The comparison function is actually unstable because a
tcp socket can be closed while we do the sorting.

**Solution**
Use two queues, one for factories and one for ReactiveSocket. Selecting a factory
is made using the "Power of 2 Choices" technique, and we also "age" the unselected
factories by moving them at the end of the queue. The WeightedSocket now contains
a reference to the associated factory, and closing it add back the factory to the
factory queue.

**Modification**
Move the `WeightedSocket` class inside the `LoadBalancer`, no

I created a proper constructor to `LoadBalancer` with javadoc explaining all
parameters the algorithm requires.

The `LatencySubscriber` inside the LoadBalancer treats some exceptions
particularly:

- `TimeoutException` latency is used for predicating the next latency
- `TransportException` & `ClosedChannelException` removes the ReactiveSocket
   from the active list.

`Publishers.onError` now also `cancel` the subscription.

I created a StressTest file, which stress most of the part of the Client:

- Adding/Removing new servers
- High request concurrency
- Dealing with failing/black-hole servers

Subject: [PATCH 011/824] use remaining instead of capacity generally (#121)

Replace use of capacity which is only appropriate if you know exactly what the client has given you (a whole ByteBuffer representing the relevant data). Uses remaining instead which assumes you trust your caller has given you a buffer that won't be changed during the method call, but uses position and limit to support sliced buffers.

Subject: [PATCH 012/824] Loadbalancer: Add a ReactiveSocket when none is
 available. (#119)

***Problem***
The loadbalancer doesn't find an active socket to use, it doesn't do anything
about it.

***Solution***
When the "power of two choices" algorithm failed to find a socket
after `EFFORT=5` tries, asynchronously add a new socket.

Subject: [PATCH 013/824] Loadbalancer: Move inter-arrival time as constant.
 (#120)

***Problem***
Hard-coded values in the code.

***Solution***
Move those hard-coded values into static members.

Initial inter-arrival time is 1 seconds (The average time between
two requests for a particular server). This value will be updated continuously.

Inter-arrival factor is now 500, after 500 times the default arrival time
we'll artificially decrease the load of a server so that it is selected
again. It solves the problem of server becoming temporarly latent, and
never being selected again.

Subject: [PATCH 014/824] ClientBuilder: Disable default timeout, remove
 retries. (#118)

* ClientBuilder: Disable default timeout, remove retries.

***Problem***
There's presently no way to disable timeouts/retries other than manually
composing the stack.

***Solution***
Default to disable any timeout in the ClientBuilder, remove completely retries.

***Modification***
Also remove unused fields `backupQuantile`, `counter` and `name`.

Subject: [PATCH 015/824] Loadbalancer: Only reduce aperture based on active
 sockets (not pending). (#124)

***Problem***
The decision of reducing the aperture is based on the number of active sockets
+ the number of pending socket. This could be bad as we close sockets before
the pending ones connect, which should leave us under the aperture target.

***Solution***
Only reduce the aperture when the number of *active* socket is below the
aperture.

***Modification***
I also increase the aperture only when we have available factories in
order to reduce the debug log.
Reduce the log level of these logs to DEBUG.

Subject: [PATCH 016/824] Add meaningfull toString() methods to most objects.
 (#122)

* Add meaningfull toString() methods to most objects.

***Problem***
Debuging and Logging could be improved by adding meaningful `toString()`
methods (that expose internal state).

***Solution***
Add meaningful `toString()` methods.

***Modification***
- Remove unused chaining functions.
- Change visibility (to protected) of the `child` factory in ReactiveSocketFactory.

Subject: [PATCH 017/824] Generics correctness in `ClientBuilder` (#125)

#### Problem

`ClientBuilder.withSource()` takes an argument of `Publisher<Collection<T>>` which means it doesn't accept an `Publisher<List<T>>`.
`Eureka` is providing `Publisher<List<T>>` so it is incompatible with `ClientBuilder`

#### Modification

Changed `ClientBuilder.withSource()` to take `Publisher<? extends Collection<T>>`.
Also changed `Eureka` to return `Publisher<Collection<T>>` which is the correct thing to do as returning a `List` doesn't really make a difference.

Subject: [PATCH 018/824] Filter non-up instances in Eureka (#126)

* Filter non-up instances in Eureka

#### Problem

Eureka source does not currently filter messages if `status != UP`. This means that on graceful shutdown of servers, `LoadBalancer` will not sending requests to the server, till it is shutdown.

#### Modification

Filter all messages that do not have status as `UP`

#### Result

More graceful removal of shutting down instances.

Subject: [PATCH 019/824] Refactor of TCP transport. (#134)

Problem

This is a split of PR #106 to make local transport use TCP.
There seems to be some issue in netty's local transport which creates race-conditions and causes test failures.
These refactor has some changes that are not necessarily related to local transport but makes the usage better.

Modification

Refactored common test classes to `reactivesocket-test` module so they can be used in both tcp and local transport without code duplication.
Added `PayloadImpl` as a utility implementation of `Payload`.

Subject: [PATCH 020/824] Publishers cleanup and new functions (#127)

#### Problem

`Publishers.retry()` had the following bugs:

- Retry subscription was sending duplicate `onSubscribe` callbacks to the downstream subscribers. This is illegal according to spec.
- Flow control was not properly managed if the error happens after a few emissions.

Since we have removed retry functionality from the `ClientBuilder` there is no reason to maintain this code.

`Publishers` was not wiring the downstream subscriber cancellation to the cancellation of the `Subscriber`. This means that a cancel followed by `onNext` would not have stopped the emission, which although not necessary (because of the inherent race between cancel and emissions) but is good to have.

 #### Modification

 - Removed `RetrySocket` and `Publishers.retry()` since they are not used.
 - Added (moved from `PublisherUtils`) `.empty()`, `.just()` and `.error()` to `Publishers`
 - Added `concatEmpty()` to `Publishers`. This is required in places where we concat `Publisher<Void>` in custom crafter code. (I will send another PR which is to use this operator in `ReactiveSocket.close()`
 - Added tests for functions in `Publishers`.

Subject: [PATCH 021/824] =build #138 Depend on the right RS version (#139)

See more details explained in https://github.com/ReactiveSocket/reactivesocket-java/issues/138
I can elaborate on the complete story if you're keen on getting the whole story, however in general the simple rule is "ignore 1.0.0.final exists" :)

Subject: [PATCH 022/824] `FailingReactiveSocket` violates spec (#136)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

#### Problem

`FailingReactiveSocket` was invoking `Subscriber.onError()` without calling `onSubscribe()` which is invalid as per reactive-streams spec:

https://github.com/reactive-streams/reactive-streams-jvm#api-components

```
This means that onSubscribe is always signalled, followed by a possibly unbounded number of onNext signals (as requested by Subscriber) followed by an onError signal if there is a failure, or an onComplete signal when no more elements are available—all as long as the Subscription is not cancelled.
```

#### Modification

Modified to use `Publishers.error()` which follows the spec correctly.

#### Result

Better adherence of spec, happy users :)

Subject: [PATCH 023/824] Fixes #132 (Cancel before `RequestN`) (#133)

#### Problem

As described in #132, All `Subscription` implementations in`Requester` were not handling the condition where a `cancel` is issued before `requestN`.

#### Modification

Correctly handle this condition and also short-circuit for multiple cancellations and `requestN()` post `cancel()`.
Added Unit tests to verify this for all interaction models.

#### Result

No `NullPointerException`

Subject: [PATCH 024/824] Subscriber cleanup (#137)

Problem

Publishers was using different implementations of CancellableSubscriber to provide different callbacks using inheritance. eg: by providing methods like doOnNext, doOnCancel, etc.

This is problematic as it requires calls to super.do* by implementator. Also, it created unnecessary class hierarchy with little benefit.

(Edit: Adding more context from the comments below)

There were 3 classes CancellableSubscriber, SafeCancellableSubscriber and SafeCancellableSubscriberProxy, each of them would override some of the methods from Subscriber. eg: doOnCancel was something that was to be used by SafeCancellableSubscriber and CancellableSubscriber in a way that SafeCancellableSubscriber had to implement doOnCancel and provide yet another method doOnCancel0 which if implemented by SafeCancellableSubscriberProxy will have to provide yet another protected method.
So, I figured not only the approach was error prone it was painful to code and maintain. Thus this approach where in specific callbacks can be overridden and controlled by the caller.

Modification

Rolled up all implementations into a single class that takes various callbacks as different lambdas.
This is easier to use and there are less chances of errors when the implementor forgot to call super methods.

Thanks @yschimke for the comment in PR #127 which led me to change the approach.

Subject: [PATCH 025/824] Fixes issue #128 (Close on `DuplexConnection`) (#140)

* Fixes issue #128 (Close on `DuplexConnection`)

As described in the issue, currently `ReactiveSocket` does not listen to `DuplexConnection` closures.

As suggested in the issue, removed `onShutdown()` and `shutdown()` methods, in favor of `close()` and `onClose()` methods.
Added `close()` and `onClose()` methods in `DuplexConnection`

Subject: [PATCH 026/824] `ClientBuilder.build` is now asynchronous. (#141)

* `ClientBuilder.build` is now asynchronous.

***Problem***
The ClientBuilder `build` API return a ReactiveSocket.
This ReactiveSocket is returned while connections are still in establishing
mode, then it will fail until the connections established.
The current solution is to call `Unsafe.awaitAvailability` which is cluncky.

***Solution***
Create a more robust API that return a `Publisher<ReactiveSocket>`, it is now
obvious that the API is asynchronous.

***Modification***
I found a bug in `sourceToFactory`, where I was calling `subscriber.onSubscribe`
before initializing the `current` Map.

Subject: [PATCH 027/824] Cleanup of unused classes in
 `io.reactivesocket.internal.rx` (#144)

***Problem***
We have a lot of copy/pasted classes from RxJava 2, that we're not using.

***Soltion***
Remove them.

Subject: [PATCH 028/824] ReactiveSocket: Remove `startAndWait` method (#143)

* ReactiveSocket: Remove `startAndWait` method

***Problem***
ReactiveSocket shouldn't have a public API encouraging usage of blocking code.

***Solution***
Remove the method, replace it by `start` where it was easy and
by `Unsafe.startAndWait` elsewhere.

Subject: [PATCH 029/824] Remove `ReactiveSocketFactory.remote()` (#145)

***Problem***
Since the refactoring of the `LoadBalancer` to use `List` instead of `Map`,
there's no need for a `remote` method that identify a remote server.
Furthermore, that's the only reason why LoadBalancer is generic.

***Solution***
Delete the method `ReactiveSocketFactory.remote()` as well as all the
references to it.

Subject: [PATCH 031/824] int overflow in `requestN` for `Responder` (#146)

#### Problem

`ReactiveSocket` expects `requestN` to be an `int` whereas `ReactiveStreams` expects it to be a `long`.
`Responder` does not correctly convert `long` to `int` for values greater than `Integer.MAX_VALUE`. This sends `-1` as the `requestN` value of the `RequestN` frame.

#### Modification

If the value is greater than `Integer.MAX_VALUE`, use `Integer.MAX_VALUE` instead.

#### Result

We will not send invalid values over the wire for `RequestN`.

Subject: [PATCH 033/824] Fix Error flags to match the spec + review the
 `frame` package. (#151)

***Problem***
There is an error in the Error frame, the error codes used for `APPLICATION_ERROR`,
`REJECTED`, `CANCELED` and `INVALID` were invalid.

***Solution***
Update the constants.
I don't think it requires doing any version bump, since the error code was not used
prior to #150.

***Modification***
I also took the oportunity to review the `frame` package and update it to the Java
code style.

Subject: [PATCH 034/824] Properly propagate exceptions type from server
 client. (#150)

***Problem***
Errors generated from the `Responder` are serialized according to the spec
https://github.com/ReactiveSocket/reactivesocket/blob/master/Protocol.md#error-codes
but the type is lost when deserializing by the `Requester`.

***Solution***
Instead of generating a RuntimeException containing the string of the error,
generate the right Exception type based on the error code.
This allow user code, or filter to make smart decision based on the Exception
type (Retryable, ...)

Subject: [PATCH 035/824] Loadbalancer: closing doesn't subscribe to the
 underlying (#148)

* Loadbalancer: closing doesn't subscribe to the underlying

***Problem***
Closing the loadbalancer doesn't properly subscribe to the `Publisher`s
returned by the `close()` methods of the underlying `ReactiveSocket`.
Thus, the close event is lost at the LoadBalancer level.

***Solution***
Properly subscribe to the close `Publisher`s and propagate the `onComplete`
events when all `ReactiveSocket` are closed. (I choose to ignore any exception
that happened during the close, i.e. only propagate 1 `onComplete`).

* Address comments

Subject: [PATCH 037/824] Fix SETUP flags according to the spec (#155)

***Problem***
The flags used in the SETUP frame are different from the one defined in the specification.
They are defined as a byte (8bits) vs. a short (16bits)
(See https://github.com/ReactiveSocket/reactivesocket/blob/master/Protocol.md#setup-frame)

***Solution***
Update the constant to the right value.

It should have been fixed in #151, that was an oversight from my part.

Subject: [PATCH 039/824] Fix Responder leak in LeaseGovernor (#156)

***Problem***
There's currently a leak of responder reference in the `LeaseGovernor`,
upon disconnection, the `Responder` is not removing its reference from the
Governor.

***Solution***
On cancel/disconnection/exception the Responder is now removing itself.

I tested that with the JS and Java client.
The `TestConnection` doesn't make disconnection testing possible with the
present code, I'll improve this in another commit.

***Modification***
I also clean-up the code-style of PublisherUtils.

Subject: [PATCH 040/824] More fairness for the FairLeaseGovernor (#157)

***Problem***
The `FairLeaseGovernor` currently distributes its budget among the connected
peers. It does so by dividing its total budget by the number of connected clients,
and add the remaining budget (`n`) among the first `n` responders.

This is fine when the budget is far greater than the number of clients, but in the
opposite situation, it leads to client starving, as the budget is always distributed
in the same order.

***Solution***
Shuffle the list of client prior to distributing the budget.

+# ReactiveSocket TCK Drivers
+
+This is meant to be used in conjunction with the TCK at [reactivesocket-tck](https://github.com/ReactiveSocket/reactivesocket-tck)
+
+## Basic Idea and Organization
+
+The philosophy behind the TCK is that it should allow any implementation of ReactiveSocket to verify itself against any other
+implementation. In order to provide a truly polyglot solution, we determined that the best way to do so was to provide a central
+TCK repository with only the code that generates the intermediate script, and then leave it up to implementers to create the
+drivers for their own implementation. The script was created specifically to be easy to parse and implement drivers for,
+and this Java driver is the first driver to be created as the Java implementation of ReactiveSockets is the most mature at
+the time.
+
+The driver is organized with a simple structure. On both the client and server drivers, we have the main driver class that
+do an intial parse of the script files. On the server side, this process basically constructs dynamic request handlers where
+every time a request is received, the appropriate behavior is searched up and is passed to a ParseMarble object, which is run
+on its own thread and is used to parse through a marble diagram and enact it's behavior. On the client side, the main driver
+class splits up each test into it's own individual lines, and then runs each test synchronously in its own thread. Support
+for concurrent behavior can easily be added later.
+
+On the client side, for the most part, each test thread just parses through each line of the test in order, synchronously and enacts its
+behavior on our TestSubscriber, a special subscriber that we can use to verify that certain things have happened. `await` calls
+should block the main test thread, and the test should fail if a single assert fails.
+
+Things get trickier with channel tests, because the client and server need to have the same behavior. In channel tests on both
+sides, the driver creates a ParseChannel object, which parses through the contents of a channel tests and handles receiving
+and sending data. We use the ParseMarble object to handle sending data. Here, we have one thread that continuously runs `parse()`,
+and other threads that run `add()` and `request()`, which stages data to be added and requested.
+
+
+
+## Run Instructions
+
+You can build the project with `gradle build`.
+You can run the client and server using the `run` script with `./run [options]`. The options are:
+
+`--server` : This is if you want to launch the server
+
+`--client` : This is if you want to launch the client
+
+`--host <h>` : This is for the client only, determines what host to connect to
+
+`--port <p>` : If launching as client, tells it to connect to port `p`, and if launching as server, tells what port to server on
+
+`--file <f>` : The path to the script file. Make sure to give the server and client the correct file formats
+
+`--debug` : This is if you want to look at the individual frames being sent and received by the client

 `--debug` : This is if you want to look at the individual frames being sent and received by the client
 
+`--tests` : This allows you, when you're running the client, to specify the tests you want to run by name. Each test
+should be comma separated.
+
+Examples:
+`./run.sh --server --port 4567 --file src/test/resources/servertest.txt` should start up a server  on port `4567` that
+has its behavior determined by the file `servertest.txt`.
+
+`./run.sh --client --host localhost --port 4567 --file src/test/resources/clienttest.txt --debug --tests genericTest,badTest` should
+start the client and have it connect to localhost on port `4567` and load the tests in `clienttest.txt` in debug mode,
+and only run the tests named `genericTest` and `badTest`.

+ * An abstraction to convert a {@link Publisher} to send it over a {@code ReactiveSocket} connection. In order to
+ * achieve that, this class provides the following contracts:
+ *
+ * <ul>
+ * <li>A {@link Publisher} that can be written to a {@code DuplexConnection} using
+ {@link DuplexConnection#send(Publisher)}</li>
+ * <li>A {@link Subscriber} that subscribes to the original data {@code Publisher}</li>
+ * <li>A {@link Subscription} that can be used to accept cancellations and flow control, typically from the peer of the
+ * {@code ReactiveSocket}.</li>
+ * </ul>
+ *
+ * <h2>Subscriptions</h2>
+ *
+ * Logically there are two subscriptions to this {@code Processor}. One from {@link DuplexConnection#send(Publisher)}
+ * and other <em>logical</em> subscription from the peer of the {@code ReactiveSocket} this stream is sent to.
+ * The {@link Subscription} contract on this class is to receive {@code Subscription} signals from the remote peer i.e.
+ * typically via a {@code RequestN} and {@code Cancel} frames. However, cancellations may be used to signal a cancel of
+ * the write, typically due to clean shutdown of the associated {@code ReactiveSocket}.
+ *
+ * <h2>Flow Control</h2>
+ *
+ * This class mediates between the flow control between the transport and {@code ReactiveSocket} peer, so
+ * to make sure that a higher demand from transport does not overwrite lower demand from the peer and vice-versa.
+ * This feature is different than a regular {@link Processor}.
+ *
+ * <h2>Flow control with terminal events</h2>
+ *
+ * Since, reactive-streams terminal events ({@code onComplete} and {@code onError}) are not flow controlled and
+ * {@code ReactiveSocket} requires the terminal frames to be sent over the wire, this may bring a situation where
+ * transport is not available to write and hence these terminal signals have to be buffered. This is the only place
+ * where frames are buffered, otherwise, {@link #onNext(Frame)} here would not buffer or check for flow control.

 ## Overview
 
-This module provides support for encoding/decoding ReactiveSocket data and metadata into using different mime types as defined by [ReactiveSocket protocol](https://github.com/ReactiveSocket/reactivesocket/blob/master/Protocol.md#setup-frame).
+This module provides support for encoding/decoding ReactiveSocket data and metadata into using different mime types as defined by [ReactiveSocket protocol](https://github.com/ReactiveSocket/reactivesocket/blob/master/Protocol.md#sendSetupFrame-frame).
 The support for mime types is not comprehensive but it will at least support the [default metadata mime type](https://github.com/ReactiveSocket/reactivesocket/blob/mimetypes/MimeTypes.md)

-# ReactiveSocket TCK Drivers
-
-This is meant to be used in conjunction with the TCK at [reactivesocket-tck](https://github.com/ReactiveSocket/reactivesocket-tck)
-
-## Basic Idea and Organization
-
-The philosophy behind the TCK is that it should allow any implementation of ReactiveSocket to verify itself against any other
-implementation. In order to provide a truly polyglot solution, we determined that the best way to do so was to provide a central
-TCK repository with only the code that generates the intermediate script, and then leave it up to implementers to create the
-drivers for their own implementation. The script was created specifically to be easy to parse and implement drivers for,
-and this Java driver is the first driver to be created as the Java implementation of ReactiveSockets is the most mature at
-the time.
-
-The driver is organized with a simple structure. On both the client and server drivers, we have the main driver class that
-do an intial parse of the script files. On the server side, this process basically constructs dynamic request handlers where
-every time a request is received, the appropriate behavior is searched up and is passed to a ParseMarble object, which is run
-on its own thread and is used to parse through a marble diagram and enact it's behavior. On the client side, the main driver
-class splits up each test into it's own individual lines, and then runs each test synchronously in its own thread. Support
-for concurrent behavior can easily be added later.
-
-On the client side, for the most part, each test thread just parses through each line of the test in order, synchronously and enacts its
-behavior on our TestSubscriber, a special subscriber that we can use to verify that certain things have happened. `await` calls
-should block the main test thread, and the test should fail if a single assert fails.
-
-Things get trickier with channel tests, because the client and server need to have the same behavior. In channel tests on both
-sides, the driver creates a ParseChannel object, which parses through the contents of a channel tests and handles receiving
-and sending data. We use the ParseMarble object to handle sending data. Here, we have one thread that continuously runs `parse()`,
-and other threads that run `add()` and `request()`, which stages data to be added and requested.
-
-
-
-## Run Instructions
-
-You can build the project with `gradle build`.
-You can run the client and server using the `run` script with `./run [options]`. The options are:
-
-`--server` : This is if you want to launch the server
-
-`--client` : This is if you want to launch the client
-
-`--host <h>` : This is for the client only, determines what host to connect to
-
-`--port <p>` : If launching as client, tells it to connect to port `p`, and if launching as server, tells what port to server on
-
-`--file <f>` : The path to the script file. Make sure to give the server and client the correct file formats
-
-`--debug` : This is if you want to look at the individual frames being sent and received by the client
-
-`--tests` : This allows you, when you're running the client, to specify the tests you want to run by name. Each test
-should be comma separated.
-
-Examples:
-`./run.sh --server --port 4567 --file src/test/resources/servertest.txt` should start up a server  on port `4567` that

Subject: [PATCH 050/824] Client is not receiving leases

#### Problem

`ClientServerInputMultiplexer` is not sending any stream 0 frames to `ClientReactiveSocket`. Since, leases come on stream 0, clients were not receiving the leases.

#### Modification

Modified `ClientServerInputMultiplexer` to send stream 0 frames to both sockets (since both ends receive frames on stream 0) and let them decide which ones are useful for them.

Also modified `FairLeaseDistributor` to subscribe to ticks after the first socket is registered. This provides predictable behavior w.r.t the first lease distribution i.e. if the lease ticks start on subscription, generally the first lease is missed by the first socket.

#### Result

Clients now receive leases.

Subject: [PATCH 051/824] Payload support for`SetupProvider`

#### Problem

`SetupProvider` currently does not provide a way to specify data and metadata for the setup frame.

#### Modification

Add a method `setupPayload(Payload)` to support optionally specifying a payload for the setup frame. Default is empty still metadata and data.

#### Result

Now data or metadata can be specified for a setup from the client.

 `io.reactivesocket.aeron.internal.reactivestreams.AeronChannelTest` and
 `io.reactivesocket.aeron.internal.reactivestreams.AeronClientServerChannelTest`

The tests fails on travis all the time.

Ignored it for now. I am not yet clear about the reason for the failure.

Travis build should pass now and so other PRs can be validated.

Subject: [PATCH 054/824] Do not send lease frames for clients which do not
 honor leases.

Today server sends leases even though the client does not honor leases. There are two things here:

- A server should protect itself, even if the client dishonors leases, i.e. leases aren't infinite if the client does not honor. So, the server should still expect requests within capacity from clients and reject all other requests.
- Clients should not receive lease frames as they are not relevant.

Modified `ServerReactiveSocket` to not send leases when the setup is such that client does not honor leases.
Also, added an override in `SetupProvider` to be able to modify the `DisableLeaseSocket` if required.

Expected results and optimizations on the wire w.r.t data transfers.

Subject: [PATCH 055/824] ReactiveSocket frame logger (tcp)

#### Problem

Tracking ReactiveSocket frames is not easy with wire logging as it logs the bytes written/read.

#### Modification

Added a netty handler to be added as the first handler in the pipeline and logs frame objects as-is written and read on the channel.
Following netty's logging handler design, this handler can be configured to log at a particular log level, which can be changed by the user at runtime.

#### Result

Better tracking of ReactiveSocket frames on the channel.

Subject: [PATCH 056/824] Microbenchmarks for tcp and local (#184)

#### Problem

No benchmarks for transports.

#### Modification

Added a benchmark to compare request-response across multiple transports. Added local and tcp for now.

#### Result

Benchmark to give some idea about how different changes impact the perf.

Subject: [PATCH 057/824] Proper shutdown on underlying connection close.

#### Problem

`ClientReactiveSocket` and `ServerReactiveSocket` does not cleanup state (unsubscribe keepalive, leases, etc) when the underlying connection is closed by the peer.
This causes lingering keepAlive and lease writes which keeps failing and emitting errors.

#### Modification

Listen to `DuplexConnection.onClose()` and cleanup when that publisher terminates.

#### Result

Cleaner shutdown on close of connection.

Subject: [PATCH 058/824] `RemoteReceiver` handle events before subscription.
 (#185)

* `RemoteReceiver` handle events before subscription.

#### Problem

`RemoteReceiver` is used for receiving a stream over a `ReactiveSocket`, eg: `requestChannel()` request stream or `requestStream()` response.
For request stream, it may so happen that the receiver does not subscribe to the request stream. This is OK for `onNext`s but terminal events can flow in without explicit `requestN`s. `RemoteReceiver` does not handle such terminal events today.

#### Modification

Added `missedCompletion` and `missedError` to `RemoteReceiver` that correctly buffers the terminal events if there is no subscription and sends these events if and when a subscriber arrives.

#### Result

No errors when terminal events flow without subscription.

* Review comments

Fixed a concurrency bug in `RemoteReceiver` as discussed in this comment: https://github.com/ReactiveSocket/reactivesocket-java/pull/185#discussion_r86440259

Subject: [PATCH 059/824] Overlapping leases and redistribution on new connects
 (#188)

#### Problem

This PR addresses two problems:

- Typically users of `FairLeaseDistributor` would supply the same value for lease TTL and the period in which leases are distributed. In such cases, there would be a time period when new lease has not arrived and old lease is expired. This isn't a good reflection of server's intent as the server can handle the new requests but the lease has not yet reached the client.
- New clients have to wait for the next distribution tick to get leases.

#### Modified

- Modified `FairLeaseDistributor` to increase user supplied lease TTL by 10% so that leases overlap. A server can still reject requests if it is overloaded.
- Redistribute leases whenever a new client connects.

#### Result

Better leasing behavior as seen by the clients.

Subject: [PATCH 060/824] Fix for `requestChannel` and `requestStream` (#186)

In the current implementation stream and channel methods are broken.

Fixed stream and channel methods to work end to end. Also added examples for the same.
They are now implemented using the existing `RemoteReceiver` and `RemoteSender` classes.
One major problem with using `ConnectableUnicastProcessor` was that it does not discriminate between subscriber of request and sender of `requestN` and `cancel` frames. So, if the request source is completed, sending `requestN` and `cancel` frames result in them being rejected by the transport. This is one of the reasons `RemoteReceiver` and `RemoteSender` classes were created.

 __ request-response implementation is not changed in this change as that needs to be optimized for a single item request-response__

Channel and stream work now.

Subject: [PATCH 061/824] More benchmarks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Tcp benchmark only utilizes a single eventloop, there is a theory that this could limit througput. Also, how does the behavior change with increasing requests per benchmark is not answered today.

Added two benchmarks:

- A benchmark to utilize more than one TCP connection per benchmark iteration.
- A parameter to run more than one requests per benchmark iteration.

Answer more questions about performance!
Here is the last run:

```

Subject: [PATCH 062/824] `AbstractReactiveSocket.onClose()` never completes.

#### Problem

`AbstractReactiveSocket` does not implement `close()` and `onClose()` correctly. Both of them return `Px.never()`.
This makes it hard for the implementation to do any cleanup actions on close.

#### Modification

Correctly terminate `onClose` `Publisher` after close() is invoked and subscribed.
Also, added test to verify this behavior in the local transport.

#### Result

Better way to cleanup on close of `AbstractReactiveSocket`.

Subject: [PATCH 063/824] Respond to keep-alive with response flag off. (#194)

#### Problem

`ServerReactiveSocket` upon receiving a `KeepAlive` frame responds with a `KeepAlive` frame as an ack. This ack MUST not have respond flag set to true. Doing so will result in an infinite loop of keep-alive frames sent between the peers.

#### Modification

`ServerReactiveSocket` responds with the respond flag turned off.

#### Result

No infinite loop of keep-alive frames.

Subject: [PATCH 064/824] Extract interface `Availability` (#191)

* Extract interface `AvailabilityProvider`

#### Problem

`DuplexConnection`, `ReactiveSocket` and `ReactiveSocketClient` all provide a method `double availability()` and so can benefit from having a common interface.
This will be useful for giving event callbacks that retrieve availability as availability follows a pull model instead of push.

#### Modification

Added a new interface `AvailabilityProvider` and have the other interfaces extend it.

#### Result

Common way to access availabilty.

* Rename `AvailabilityProvider` to `Availability`

Subject: [PATCH 065/824] Additional flags in `Frame.toString()` (#197)

#### Problem

Current `Frame.toString()` does not print the various flags associated with different frame types. eg: `requestN` value in `RequestN` frame. This limits the usefulness of frame logging.

#### Modifications

Added `additionalFlags` string which is generated per frame type.

#### Result

More insight for frame logging.

Subject: [PATCH 067/824] Fix to publish Snapshots to jfrog (#199)

#### Problem

Currently travis is publishing 0.2.3-SNAPSHOT artifacts for 0.5.x branch.

#### Modifications

I am not 100% sure if this is the correct way to make travis publish the correct version, but it is a way!
Modified `buildViaTravis.sh` to override the version, just for snapshot builds.

#### Result

Correct version number for snapshot.

Subject: [PATCH 068/824] JMH test for larger payloads (#195)

#### Problem

Current JMH tests only benchmark smaller payloads "hello". It will be good to know the numbers with larger payloads.

#### Modifications

- Refactored `RequestResponsePerf` and extracted a base class that can be used in all benchmarks.
- Added another benchmark class to test different payload sizes.

#### Result

More insight into perf.

Subject: [PATCH 069/824] added sliding window histogram (#200)

Added sliding window histogram

Problem
Current histogram doesn't resets on every get on every dimension. This creates choppy metrics.

Modifications
Modified the timer to have n histrograms in a queue and rotate of over them to smooth out the histogram over a sliding window. Switched the dimensions of the histrogram to a label called value. Switched the reseting of the histrogram to a closure that is called by the timer instead so it will rotate the histrogram once per window.

Result
Correct metrics over a rolling window.

From f69422ccdbb6cdab7e25041dd71add432f55bc22 Mon Sep 17 00:00:00 2001

Subject: [PATCH 070/824] Adding log4j as a test-dependency for all modules.

#### Problem

For all tests there is no logger implementation and hence it is difficult to debug the tests sometimes.

#### Modification

Added a `testCompile` dependency on log4j for all modules and log4j configuration file.

#### Result

No more "no logger found" warning and logs configured.

Subject: [PATCH 072/824] Empty stacktrace of `TimeoutException` (#202)

Empty stacktrace of `TimeoutException`

#### Problem

`TimeoutPublisher` creates a new `TimeoutException` instance for every timeout. This is costly when the system is under load and has a lot of timers that timeout, which is typical when handling latent outbound services.

#### Modification

Used a cached `TimeoutException` instance and empty the stacktrace of the exception.

#### Result

Less overhead of timeouts.

Subject: [PATCH 073/824] Refactored `StressTest` for easier configuration
 (#204)

#### Problem

`StressTest` is pretty useful to do blackbox testing of ReactiveSocket. It is hard to add behavior like leases, keep alive, timeouts, etc.

#### Modification

Refactored and did the following changes:

- Introduced `TestConfig` that is all that needs to be altered to do behavior changes like lease, timeouts, etc.
- Changed `StressTest` to use `TestConfig` and only contain the core logic of the test.
- Introduced a `StressTestDriver` that contains the creation of config and invocation of `StressTest`

#### Result

More powerful `StressTest` which can be used for a variety of situations.

Subject: [PATCH 075/824] Empty Payload Response treated as Complete frame
 (#206)

#### Problem

`FrameHeaderFlyweight` resolves the frame type as `NEXT_COMPLETE` only if the payload is not empty. Otherwise, the frame is treated as `COMPLETE`.
This is a problem for request-response as this means the response publisher will complete without emitting a response, if the response does not have any data. Such a condition is a failure as request-response should have exaclty one response.

 #### Modification

 Eliminated the check for data length and always emit `NEXT_COMPLETE` if the complete flag is set.
 According to the [protocol](https://github.com/ReactiveSocket/reactivesocket/blob/master/Protocol.md#response-frame):

 ```
 A Response is generally referred to as a NEXT.
 ```

 So, this behavior would not be a violation of the protocol but will produce empty `onNext` before `onComplete`

 #### Result

 Better behavior with empty responses.

Subject: [PATCH 076/824] Make `ReactiveSocket` requests lazy

__Problem__

Today a client can not retry a request by simply adding a retry operator. eg:

```java
Flowable.fromPublisher(socket.requestResponse(PayloadImpl.EMPTY)).retry()
```

does not work. Instead one has to use

```java
Flowable.fromPublisher(Flowable.defer(() -> socket.requestResponse(PayloadImpl.EMPTY)))
```

The reason is that the implementation creates a `streamId` upon calling `requestResponse` and not on each subscription.

__Modification__

Modify `ClientReactiveSocket` to create a new `streamId` per subscription. This will make sure that each subscription is unique and hence a server will not have an issue accepting such requests.

__Result__

More idiomatic usage of function composition and retry/repeat kind of models.

Subject: [PATCH 078/824] Correct call to RemoteSender - streamId and
 initialRemoteRequested (#210)

Correct call to RemoteSender - streamId and initialRemoteRequested

Seems like a typo

Two constructors are

```
public RemoteSender(Publisher<Frame> originalSource, Runnable cleanup, int streamId,  int initialRemoteRequested) {
public RemoteSender(Publisher<Frame> originalSource, Runnable cleanup, int streamId) {
```

Subject: [PATCH 080/824] Duplex interactions

#### Problem

Duplex interactions (server sending requests to the client) are broken.

#### Modification

- `ReactiveSocketServer` wasn't using `ClientServerInputMultiplexer` to split input into client and server sockets. This made the responses sent from the client to not reach `ClientReactiveSocket`. Modified `ReactiveSocketServer` to use `ClientServerInputMultiplexer`.
- `ClientReactiveSocket` didn't handle a request-stream/channel request before transport subscription arrived. Now using a buffering subscription to buffer request-n and cancel till transport subscription arrives.
- Added `DuplexClient` example to demonstrate duplex interactions.

#### Result

Duplex interactions works!

Subject: [PATCH 081/824] Resuable `Payload` (#209)

__Problem__

`PayloadImpl` caches `data` and `metadata` buffers. This means once those buffers are read, they can not be reused as the pointer of `ByteBuffer` has moved to the end of buffer.
This restricts the usage of `PayloadImpl` instance with something like:

```java
socket.requestResponse(new PayloadImpl("Hello")).retry(2);
```

For any retry in the above code, data read from the payload instance will be empty.

__Modification__

- store buffer `position()` on creation and reset them on every `get()`.
- Additional constructor to override this behavior and create a payload for single use.
- `PayloadImpl` defaults to reusable payload.

__Result__

Possible to retry a request without having a custom `Payload` implementation.

Subject: [PATCH 082/824] Replace servo usage with spectator (#219)

__Problem__

Currently, servo is being used for metric. Spectator is a more generic library and has better APIs.

__Modification__

Modified classes to use spectator-api which reduces the code considerably.
 This is a change required before we layer the events => metric changes.

__Result__

Using recommended library at Netflix for metric and lesser code.

Subject: [PATCH 084/824] Events interface (#189)

__Problem__

Insights into the internals of `ReactiveSocket` is not available for users. eg: Load balancing internals, leases sent/received, keep-alives sent/received, etc.

__Modification__

This change is first of a series of changes intended to address this problem. It only contains the core interfaces to support event publications from `ReactiveSocket` internals.

The model is adopted from the tried and tested model in `RxNetty` to provide an event publishing infrastructure that can be used to implement metrics of event firehose. One of the primary guideline of this model is to reduce the object allocations that comes along with an event stream based on emitting an event as an object. Instead, this approach embraces distinct callbacks that any listener can choose to implement if interested.

Primary classes are `EventListener` and `EventSource`. There are a few extensions of `EventListener` to provide events specific to a server, client or load balancer.

__Result__

Better insight into `ReactiveSocket` internals.

Subject: [PATCH 090/824] Spectator metric listener (#224)

__Problem__

`ReactiveSocket` publishes events about the internals but there is no out of the box listener to collect and record metrics for those events.

__Modification__

Out of the box listeners for clients and servers that publishes metrics using spectator.

__Result__

Ready to use metrics!

Subject: [PATCH 091/824] Using native spectator counter and timer (#228)

__Problem__

Currently we have custom implementation of timers and counters.
These implementations are somewhat not recognized inside Netflix and hence does not get published to our metrics system.
At this point it is better to use the native counterparts than to debug the issue, we can revert to the custom implementation when we see performance issues.

 __Modification__

 Replace custom usages with native spectator classes.

 __Result__

 Metrics correctly published.

Subject: [PATCH 092/824] LoadBalancer: remove socket on close and refresh
 sockets. (#227)

__Problem__

There are the following issues:

- `removeSocket()` was not subscribing to `socket.close()`. Since, `close()` is lazy, not subscribing will not close the socket.
- Socket is not removed when it closes, unless a request is made to it.
- `refreshSocket()` only gets called when making a request. This means that if a client awaits `availability()` when load balancer does not have any active sockets (`NoAvailableHostException`), it is a deadlock as load balancer will never add a socket if there are no requests.

__Modification__

- Subscribe to `socket.close()`
- Added a `onClose()` listener that removes the socket from the active list when it closes.
- Call `refreshSockets()` in `removeSocket()`

__ Result__

No deadlock when awaiting availability as a reaction to `NoAvailableHostException`.
Actively closed socket from LB actually gets closed.

Subject: [PATCH 094/824] Update frame header to 1.0 spec (#233)

* Update SETUP frame to 1.0 spec

Makes frame and metadata length 24 bits.
Metadata length also excludes the length field itself
Moves streamId to front
Makes frame type 6 bits and flags 10 bits
Make all used flag 10 bits

Some new unit tests to verify all this.

Subject: [PATCH 102/824] Add test to verify wire format (#245)

This test writes the expected wire format and then verifies that we encode a frame like that.
I've verified by hand that the generated format is correct:
000000000000000000001001 // size (24 bits) = 9
00000000000000000000000000000101 // stream id (32 bits) = 5
001010 // frame type (6 bits) = 0x0A
0001000000 // flags (6 bits) == COMPLETE

+# ReactiveSocket TCK Drivers
+
+This is meant to be used in conjunction with the TCK at [reactivesocket-tck](https://github.com/ReactiveSocket/reactivesocket-tck)
+
+## Basic Idea and Organization
+
+The philosophy behind the TCK is that it should allow any implementation of ReactiveSocket to verify itself against any other
+implementation. In order to provide a truly polyglot solution, we determined that the best way to do so was to provide a central
+TCK repository with only the code that generates the intermediate script, and then leave it up to implementers to create the
+drivers for their own implementation. The script was created specifically to be easy to parse and implement drivers for,
+and this Java driver is the first driver to be created as the Java implementation of ReactiveSockets is the most mature at
+the time.
+
+The driver is organized with a simple structure. On both the client and server drivers, we have the main driver class that
+do an intial parse of the script files. On the server side, this process basically constructs dynamic request handlers where
+every time a request is received, the appropriate behavior is searched up and is passed to a ParseMarble object, which is run
+on its own thread and is used to parse through a marble diagram and enact it's behavior. On the client side, the main driver
+class splits up each test into it's own individual lines, and then runs each test synchronously in its own thread. Support
+for concurrent behavior can easily be added later.
+
+On the client side, for the most part, each test thread just parses through each line of the test in order, synchronously and enacts its
+behavior on our TestSubscriber, a special subscriber that we can use to verify that certain things have happened. `await` calls
+should block the main test thread, and the test should fail if a single assert fails.
+
+Things get trickier with channel tests, because the client and server need to have the same behavior. In channel tests on both
+sides, the driver creates a ParseChannel object, which parses through the contents of a channel tests and handles receiving
+and sending data. We use the ParseMarble object to handle sending data. Here, we have one thread that continuously runs `parse()`,
+and other threads that run `add()` and `request()`, which stages data to be added and requested.
+
+
+
+## Run Instructions
+
+You can build the project with `gradle build`.
+You can run the client and server using the `run` script with `./run [options]`. The options are:
+
+`--server` : This is if you want to launch the server
+
+`--client` : This is if you want to launch the client
+
+`--host <h>` : This is for the client only, determines what host to connect to
+
+`--port <p>` : If launching as client, tells it to connect to port `p`, and if launching as server, tells what port to server on
+
+`--file <f>` : The path to the script file. Make sure to give the server and client the correct file formats
+
+`--debug` : This is if you want to look at the individual frames being sent and received by the client
+
+`--tests` : This allows you, when you're running the client, to specify the tests you want to run by name. Each test
+should be comma separated.
+
+Examples:
+`./run.sh --server --port 4567 --file src/test/resources/servertest.txt` should start up a server  on port `4567` that
+has its behavior determined by the file `servertest.txt`.
+
+`./run.sh --client --host localhost --port 4567 --file src/test/resources/clienttest.txt --debug --tests genericTest,badTest` should
+start the client and have it connect to localhost on port `4567` and load the tests in `clienttest.txt` in debug mode,
+and only run the tests named `genericTest` and `badTest`.

Subject: [PATCH 116/824] Fix initialRequestN value for requestStream (#258)

Previously, the initialRequestN value of the REQUEST_STREAM frame was
completely ignored and 2 was used instead.  Fixing it.

Tested this by running tck against cpp version and ensuring requestN
gets propagated properly to the java-publisher.

- * {@code RequestN} from the {@code Subscriber} to this {@code Publisher} are sent as-is to the remote peer and the

- * This class honors any write flow control imposed by {@link DuplexConnection#send(Publisher)} to control the

- * ready to write, no frames will be enqueued into the connection. All {@code RequestN} frames sent during such time

-/**
- * An abstraction to convert a {@link Publisher} to send it over a {@code ReactiveSocket} connection. In order to
- * achieve that, this class provides the following contracts:
- *
- * <ul>
- * <li>A {@link Publisher} that can be written to a {@code DuplexConnection} using
- {@link DuplexConnection#send(Publisher)}</li>
- * <li>A {@link Subscriber} that subscribes to the original data {@code Publisher}</li>
- * <li>A {@link Subscription} that can be used to accept cancellations and flow control, typically from the peer of the
- * {@code ReactiveSocket}.</li>
- * </ul>
- *
- * <h2>Subscriptions</h2>
- *
- * Logically there are two subscriptions to this {@code Processor}. One from {@link DuplexConnection#send(Publisher)}
- * and other <em>logical</em> subscription from the peer of the {@code ReactiveSocket} this stream is sent to.
- * The {@link Subscription} contract on this class is to receive {@code Subscription} signals from the remote peer i.e.
- * typically via a {@code RequestN} and {@code Cancel} frames. However, cancellations may be used to signal a cancel of
- * the write, typically due to clean shutdown of the associated {@code ReactiveSocket}.
- *
- * <h2>Flow Control</h2>
- *
- * This class mediates between the flow control between the transport and {@code ReactiveSocket} peer, so
- * to make sure that a higher demand from transport does not overwrite lower demand from the peer and vice-versa.
- * This feature is different than a regular {@link Processor}.
- *
- * <h2>Flow control with terminal events</h2>
- *
- * Since, reactive-streams terminal events ({@code onComplete} and {@code onError}) are not flow controlled and
- * {@code ReactiveSocket} requires the terminal frames to be sent over the wire, this may bring a situation where
- * transport is not available to write and hence these terminal signals have to be buffered. This is the only place
- * where frames are buffered, otherwise, {@link #onNext(Frame)} here would not buffer or check for flow control.

Subject: [PATCH 128/824] Fix initialRequestN value for requestStream (#258)

Previously, the initialRequestN value of the REQUEST_STREAM frame was
completely ignored and 2 was used instead.  Fixing it.

Tested this by running tck against cpp version and ensuring requestN
gets propagated properly to the java-publisher.

-## Overview
-
-This module provides support for encoding/decoding ReactiveSocket data and metadata into using different mime types as defined by [ReactiveSocket protocol](https://github.com/ReactiveSocket/reactivesocket/blob/master/Protocol.md#sendSetupFrame-frame).
-The support for mime types is not comprehensive but it will at least support the [default metadata mime type](https://github.com/ReactiveSocket/reactivesocket/blob/mimetypes/MimeTypes.md)
-
-## Usage
-
-#### Supported Codecs
-
-Supported mime types are listed as [SupportedMimeTypes](src/main/java/io/reactivesocket/mimetypes/SupportedMimeTypes.java).
-
-#### Obtaining the appropriate codec
-
-[MimeType](src/main/java/io/reactivesocket/mimetypes/MimeType.java) is the interface that provides different methods for encoding/decoding ReactiveSocket data and metadata.
-An instance of `MimeType` can be obtained via [MimeTypeFactory](src/main/java/io/reactivesocket/mimetypes/MimeTypeFactory.java).
-
-A simple usage of `MimeType` is as follows:
-
-```java
-public class ConnectionSetupHandlerImpl implements ConnectionSetupHandler {
-
-    @Override
-    public RequestHandler apply(ConnectionSetupPayload setupPayload, ReactiveSocket reactiveSocket) throws SetupException {
-
-        final MimeType mimeType = MimeTypeFactory.from(setupPayload); // If the mime types aren't supported, throws an error.
-
-        return new RequestHandler() {
-
-            // Not a complete implementation, just a method to demonstrate usage.
-            @Override
-            public Publisher<Payload> handleRequestResponse(Payload payload) {
-                // use (en/de)codeMetadata() methods to encode/decode metadata
-                mimeType.decodeMetadata(payload.getMetadata(), KVMetadata.class);
-                // use (en/de)codeData() methods to encode/decode data
-                mimeType.decodeData(payload.getData(), Person.class);
-                return PublisherUtils.empty(); // Do something useful in reality!
-            }
-        };
-    }
-}
-```
-
-## Build and Binaries
-
-<a href='https://travis-ci.org/ReactiveSocket/reactivesocket-java/builds'><img src='https://travis-ci.org/ReactiveSocket/reactivesocket-java.svg?branch=master'></a>
-
-Artifacts are available via JCenter.
-
-Example:
-
-```groovy
-repositories {
-    maven { url 'https://jcenter.bintray.com' }
-}
-
-dependencies {
-    compile 'io.reactivesocket:reactivesocket-mime-types:x.y.z'
-}
-```
-
-No releases to Maven Central have occurred yet.

-/**
- * A representation of CBOR map as defined in the <a href="https://tools.ietf.org/html/rfc7049#page-7">spec</a>. <p>
- *
- * The benefit of this class is that it does not create additional buffers for the values of the metadata, when
- * possible. Instead it holds views into the original buffer and when queried creates a slice of the underlying buffer
- * that represents the value. Thus, it is lean in terms of memory usage as compared to other standard libraries that
- * allocate memory for all values.
- *
- * <h1>Allocations</h1>
- *
- * <h2>Modifications</h2>
- *
- * Any additions to the map (adding one or more key-value pairs) will create a map with all keys and values, where
- * values are the buffer slices of the original buffer. From then onwards, the newly created map will be used for all
- * further queries. <p>
- *     So, additions to this map will result in more allocations than usual but it still does not allocate fresh memory
- *     for existing entries.
- *
- * <h2>Access</h2>
- *
- * Bulk queries like {@link #entrySet()}, {@link #values()} and value queries like {@link #containsValue(Object)} will
- * switch to a new map as described in case of modifications above.
- *
- * <h1>Structure</h1>
- *
- * In absence of the above cases for allocations, this map uses an index of {@code String} keys to a {@code Long}. The
- * first 32 bits of this {@code Long} holds the length of the value and the next 32 bits contain the offset in the
- * original buffer. {@link #encodeValueMask(int, long)} encodes this mask and {@link #decodeLengthFromMask(long)},
- * {@link #decodeOffsetFromMask(long)} decodes the mask.

Subject: [PATCH 133/824] Fix initialRequestN value for requestStream (#258)

Previously, the initialRequestN value of the REQUEST_STREAM frame was
completely ignored and 2 was used instead.  Fixing it.

Tested this by running tck against cpp version and ensuring requestN
gets propagated properly to the java-publisher.

-ReactiveSocket is network protocol with client and server that uses [Reactive Streams](http://reactive-streams.org) (and optimistically [Reactive Streams IO](http://reactive-streams.io) as it gets defined).
+RSocket is a binary protocol for use on byte stream transports such as TCP, WebSockets, and Aeron.

+It enables the following symmetric interaction models via async message passing over a single connection:
 
 - request/response (stream of 1)
 - request/stream (finite stream of many)

+The philosophy behind the TCK is that it should allow any implementation of RSocket to verify itself against any other
 implementation. In order to provide a truly polyglot solution, we determined that the best way to do so was to provide a central
 TCK repository with only the code that generates the intermediate script, and then leave it up to implementers to create the
 drivers for their own implementation. The script was created specifically to be easy to parse and implement drivers for,

Subject: [PATCH 180/824] Make Aeron compile again (#310)

On way to working aeron again.  Compiling but still failing.

"In order to use Aeron someone needs to fix the handshaking in the beginning. Basically what needs to happen is the acking that the connection is established needs to happen in the AvailableImageHandler. After the first connection subsequent connections will fail right now."

Subject: [PATCH 214/824] Refactor TCK test runner #297 (#347)

* replaced Main.java and TestMain.java my a junit based TckTest.java
* Updated JavaClientDriver.java. Removed the unused functions and variables.
made parse function and enum public
* replaced all the checks with assert statements. ConsoleUtils will be used for logging

Subject: [PATCH 222/824] Updated JavaClientDriver to support new tck test
 format. (#357)

The new TCK-test format has an option to represent multiple clients.
This commit is just to update the test files and javaclientdriver to run the new files. In a later commit, I will add support for multiple clients in the rsocket-java.

Subject: [PATCH 223/824] Added the tck-main file  (#358)

* Added a main file which I removed a while back. This is required for running cross implementation compatibility tests.

Removing this file did not break anything becuase Cross implemetation tests were using an older version of rsocket-java

Following changes are temporary
      RSocket client = createClient(this.uri);
      this.createClient = () -> client;

This part will be rewritten when I will the support for multiple clients. Each test will be run by a new client object(s).

-# RSocket TCK Drivers
-
-This is meant to be used in conjunction with the TCK at [reactivesocket-tck](https://github.com/RSocket/reactivesocket-tck)
-
-## Basic Idea and Organization
-
-The philosophy behind the TCK is that it should allow any implementation of RSocket to verify itself against any other
-implementation. In order to provide a truly polyglot solution, we determined that the best way to do so was to provide a central
-TCK repository with only the code that generates the intermediate script, and then leave it up to implementers to create the
-drivers for their own implementation. The script was created specifically to be easy to parse and implement drivers for,
-and this Java driver is the first driver to be created as the Java implementation of RSockets is the most mature at
-the time.
-
-The driver is organized with a simple structure. On both the client and server drivers, we have the main driver class that
-do an initial parse of the script files. On the server side, this process basically constructs dynamic request handlers where
-every time a request is received, the appropriate behavior is searched up and is passed to a ParseMarble object, which is run
-on its own thread and is used to parse through a marble diagram and enact it's behavior. On the client side, the main driver
-class splits up each test into it's own individual lines, and then runs each test synchronously in its own thread. Support
-for concurrent behavior can easily be added later.
-
-On the client side, for the most part, each test thread just parses through each line of the test in order, synchronously and enacts its
-behavior on our TestSubscriber, a special subscriber that we can use to verify that certain things have happened. `await` calls
-should block the main test thread, and the test should fail if a single assert fails.
-
-Things get trickier with channel tests, because the client and server need to have the same behavior. In channel tests on both
-sides, the driver creates a ParseChannel object, which parses through the contents of a channel tests and handles receiving
-and sending data. We use the ParseMarble object to handle sending data. Here, we have one thread that continuously runs `parse()`,
-and other threads that run `add()` and `request()`, which stages data to be added and requested.
-
-
-
-## Run Instructions
-
-You can build the project with `gradle build`.
-You can run the client and server using the `run` script with `./run [options]`. The options are:
-
-`--server` : This is if you want to launch the server
-
-`--client` : This is if you want to launch the client
-
-`--host <h>` : This is for the client only, determines what host to connect to
-
-`--port <p>` : If launching as client, tells it to connect to port `p`, and if launching as server, tells what port to server on
-
-`--file <f>` : The path to the script file. Make sure to give the server and client the correct file formats
-
-`--debug` : This is if you want to look at the individual frames being sent and received by the client
-
-`--tests` : This allows you, when you're running the client, to specify the tests you want to run by name. Each test
-should be comma separated.
-
-Examples:
-`./run.sh --server --port 4567 --file src/test/resources/servertest.txt` should start up a server  on port `4567` that
-has its behavior determined by the file `servertest.txt`.
-
-`./run.sh --client --host localhost --port 4567 --file src/test/resources/clienttest.txt --debug --tests genericTest,badTest` should
-start the client and have it connect to localhost on port `4567` and load the tests in `clienttest.txt` in debug mode,
-and only run the tests named `genericTest` and `badTest`.

+/**
+ * A lock-free alternate implementation of {@link java.util.concurrent.ConcurrentHashMap}
+ * with better scaling properties and generally lower costs to mutate the Map.
+ * It provides identical correctness properties as ConcurrentHashMap.  All
+ * operations are non-blocking and multi-thread safe, including all update
+ * operations.  {@link NonBlockingHashMap} scales substantially better than
+ * {@link java.util.concurrent.ConcurrentHashMap} for high update rates, even with a
+ * large concurrency factor.  Scaling is linear up to 768 CPUs on a 768-CPU
+ * Azul box, even with 100% updates or 100% reads or any fraction in-between.
+ * Linear scaling up to all cpus has been observed on a 32-way Sun US2 box,
+ * 32-way Sun Niagara box, 8-way Intel box and a 4-way Power box.
+ *
+ * This class obeys the same functional specification as {@link
+ * Hashtable}, and includes versions of methods corresponding to
+ * each method of <tt>Hashtable</tt>. However, even though all operations are
+ * thread-safe, operations do <em>not</em> entail locking and there is
+ * <em>not</em> any support for locking the entire table in a way that
+ * prevents all access.  This class is fully interoperable with
+ * <tt>Hashtable</tt> in programs that rely on its thread safety but not on
+ * its synchronization details.
+ *
+ * <p> Operations (including <tt>put</tt>) generally do not block, so may
+ * overlap with other update operations (including other <tt>puts</tt> and
+ * <tt>removes</tt>).  Retrievals reflect the results of the most recently
+ * <em>completed</em> update operations holding upon their onset.  For
+ * aggregate operations such as <tt>putAll</tt>, concurrent retrievals may
+ * reflect insertion or removal of only some entries.  Similarly, Iterators
+ * and Enumerations return elements reflecting the state of the hash table at
+ * some point at or since the creation of the iterator/enumeration.  They do
+ * <em>not</em> throw {@link ConcurrentModificationException}.  However,
+ * iterators are designed to be used by only one thread at a time.
+ *
+ * <p> Very full tables, or tables with high re-probe rates may trigger an
+ * internal resize operation to move into a larger table.  Resizing is not
+ * terribly expensive, but it is not free either; during resize operations
+ * table throughput may drop somewhat.  All threads that visit the table
+ * during a resize will 'help' the resizing but will still be allowed to
+ * complete their operation before the resize is finished (i.e., a simple
+ * 'get' operation on a million-entry table undergoing resizing will not need
+ * to block until the entire million entries are copied).
+ *
+ * <p>This class and its views and iterators implement all of the
+ * <em>optional</em> methods of the {@link Map} and {@link Iterator}
+ * interfaces.
+ *
+ * <p> Like {@link Hashtable} but unlike {@link HashMap}, this class
+ * does <em>not</em> allow <tt>null</tt> to be used as a key or value.

+/**
+ * A lock-free alternate implementation of {@link java.util.concurrent.ConcurrentHashMap}
+ * with <strong>primitive long keys</strong>, better scaling properties and
+ * generally lower costs.  The use of {@code long} keys allows for faster
+ * compares and lower memory costs.  The Map provides identical correctness
+ * properties as ConcurrentHashMap.  All operations are non-blocking and
+ * multi-thread safe, including all update operations.  {@link
+ * NonBlockingHashMapLong} scales substatially better than {@link
+ * java.util.concurrent.ConcurrentHashMap} for high update rates, even with a large
+ * concurrency factor.  Scaling is linear up to 768 CPUs on a 768-CPU Azul
+ * box, even with 100% updates or 100% reads or any fraction in-between.
+ * Linear scaling up to all cpus has been observed on a 32-way Sun US2 box,
+ * 32-way Sun Niagra box, 8-way Intel box and a 4-way Power box.
+ *
+ * <p><strong>The main benefit of this class</strong> over using plain {@link
+ * io.rsocket.util.NonBlockingHashMap} with {@link Long} keys is
+ * that it avoids the auto-boxing and unboxing costs.  Since auto-boxing is
+ * <em>automatic</em>, it is easy to accidentally cause auto-boxing and negate
+ * the space and speed benefits.
+ *
+ * <p>This class obeys the same functional specification as {@link
+ * Hashtable}, and includes versions of methods corresponding to
+ * each method of <tt>Hashtable</tt>.  However, even though all operations are
+ * thread-safe, operations do <em>not</em> entail locking and there is
+ * <em>not</em> any support for locking the entire table in a way that
+ * prevents all access.  This class is fully interoperable with
+ * <tt>Hashtable</tt> in programs that rely on its thread safety but not on
+ * its synchronization details.
+ *
+ * <p> Operations (including <tt>put</tt>) generally do not block, so may
+ * overlap with other update operations (including other <tt>puts</tt> and
+ * <tt>removes</tt>).  Retrievals reflect the results of the most recently
+ * <em>completed</em> update operations holding upon their onset.  For
+ * aggregate operations such as <tt>putAll</tt>, concurrent retrievals may
+ * reflect insertion or removal of only some entries.  Similarly, Iterators
+ * and Enumerations return elements reflecting the state of the hash table at
+ * some point at or since the creation of the iterator/enumeration.  They do
+ * <em>not</em> throw {@link ConcurrentModificationException}.  However,
+ * iterators are designed to be used by only one thread at a time.
+ *
+ * <p> Very full tables, or tables with high reprobe rates may trigger an
+ * internal resize operation to move into a larger table.  Resizing is not
+ * terribly expensive, but it is not free either; during resize operations
+ * table throughput may drop somewhat.  All threads that visit the table
+ * during a resize will 'help' the resizing but will still be allowed to
+ * complete their operation before the resize is finished (i.e., a simple
+ * 'get' operation on a million-entry table undergoing resizing will not need
+ * to block until the entire million entries are copied).
+ *
+ * <p>This class and its views and iterators implement all of the
+ * <em>optional</em> methods of the {@link Map} and {@link Iterator}
+ * interfaces.
+ *
+ * <p> Like {@link Hashtable} but unlike {@link HashMap}, this class
+ * does <em>not</em> allow <tt>null</tt> to be used as a value.

Subject: [PATCH 301/824] Gradle Improvements (#475)

This change contributes some improvements to the Gradle build.

The most significant change is the introduction of the io.spring.dependency-
management plugin.  Don't let the name fool you, while this plugin was created
for the Spring teams, it's generally applicable for all users of Gradle.  This
plugin allows you to define a dependencyManagement section (equivalent of the
Maven construct of the same name).  The information about the dependencies in
that section is then used by each subproject to include dependencies without
needing to specify a version number.  This solves the problem of keeping
groups of dependencies in sync with one another across projects and
centralizes all the versions into a single location that can be quickly
updated when necessary.

dependencyManagement {
  dependencies {
    dependency 'junit:junit:4.12'
  }
}

dependencies {
  testImplementation 'junit:junit'
}

The second important change is the update of projects so that they now use the
Gradle 'java-library' plugin instead of the 'java' plugin.  This plugin is
more modern, is considered idiomatic and allows much more control of the
dependencies that a library exposes in it's POM as compile-time dependencies.

Next, the build now minimizes the collection of artifacts that are published
to Artifactory and Bintray repositories.  Specifically, it ensures that the
'rsocket-examples' and 'rsocket-test' JARs are not published with the rest of
the globally useful artifacts.

The Artifactory and Bintray configurations have been split out into separate
build scripts.  This modularity encapsulates each publishing location's
configuration and isolates it from the other.  It also has the side-benefit of
removing noise from the main build script which is much more focused on
compiling code and creating JARs.  At this time, I'm pretty confident in the
configuration of the Artifactory, Bintray, and Maven Central configurations,
but only actual publication to each will be able to verify that there were no
regressions.

Finally, dependencies were updated and Gradle configuration was streamlined
(removing redundant declaration of defaults) to generally speed up and shrink
the build.

Subject: [PATCH 302/824] Maven Central POM Requirements (#477)

In order to publish to Maven Central, POMs must contain a minimum set of
elements.  The automatically generated POM from Gradle's 'maven-publish'
plugin does not contain these elements.  This change adds build functionality
to ensure that the generated POMs are Maven Central compatible.

Subject: [PATCH 303/824] Shadow JCTools (#476)

Previously, a number of classes from JCTools had been copied and pasted into
the code in order to avoid a JAR-level dependencies on the project.  While the
goal was worthy, the implementation led itself to divergence as the classes in
JCTools were improved and bugs were fixed.  Even the JCTools project
discourages this behavior, instead recommending that you shadow/shade in the
dependency.  From the RSocket perspective, this has the advantage of allowing
the dependency to be specified and kept up to date in the same way that all
the other dependencies of the projects are, and yet still not resulting in a
JAR-level dependency on JCTools.

This change updates the code to use JCTools directly as a dependency and
introduces the shadow plugin, configured to include just the types needed by
the code.

-/**
- * A lock-free alternate implementation of {@link java.util.concurrent.ConcurrentHashMap} with
- * better scaling properties and generally lower costs to mutate the Map. It provides identical
- * correctness properties as ConcurrentHashMap. All operations are non-blocking and multi-thread
- * safe, including all update operations. {@link NonBlockingHashMap} scales substantially better
- * than {@link java.util.concurrent.ConcurrentHashMap} for high update rates, even with a large
- * concurrency factor. Scaling is linear up to 768 CPUs on a 768-CPU Azul box, even with 100%
- * updates or 100% reads or any fraction in-between. Linear scaling up to all cpus has been observed
- * on a 32-way Sun US2 box, 32-way Sun Niagara box, 8-way Intel box and a 4-way Power box.
- *
- * <p>This class obeys the same functional specification as {@link java.util.Hashtable}, and
- * includes versions of methods corresponding to each method of <tt>Hashtable</tt>. However, even
- * though all operations are thread-safe, operations do <em>not</em> entail locking and there is
- * <em>not</em> any support for locking the entire table in a way that prevents all access. This
- * class is fully interoperable with <tt>Hashtable</tt> in programs that rely on its thread safety
- * but not on its synchronization details.
- *
- * <p>Operations (including <tt>put</tt>) generally do not block, so may overlap with other update
- * operations (including other <tt>puts</tt> and <tt>removes</tt>). Retrievals reflect the results
- * of the most recently <em>completed</em> update operations holding upon their onset. For aggregate
- * operations such as <tt>putAll</tt>, concurrent retrievals may reflect insertion or removal of
- * only some entries. Similarly, Iterators and Enumerations return elements reflecting the state of
- * the hash table at some point at or since the creation of the iterator/enumeration. They do
- * <em>not</em> throw {@link ConcurrentModificationException}. However, iterators are designed to be
- * used by only one thread at a time.
- *
- * <p>Very full tables, or tables with high re-probe rates may trigger an internal resize operation
- * to move into a larger table. Resizing is not terribly expensive, but it is not free either;
- * during resize operations table throughput may drop somewhat. All threads that visit the table
- * during a resize will 'help' the resizing but will still be allowed to complete their operation
- * before the resize is finished (i.e., a simple 'get' operation on a million-entry table undergoing
- * resizing will not need to block until the entire million entries are copied).
- *
- * <p>This class and its views and iterators implement all of the <em>optional</em> methods of the
- * {@link Map} and {@link Iterator} interfaces.
- *
- * <p>Like {@link Hashtable} but unlike {@link HashMap}, this class does <em>not</em> allow
- * <tt>null</tt> to be used as a key or value.

-/**
- * A lock-free alternate implementation of {@link java.util.concurrent.ConcurrentHashMap} with
- * <strong>primitive long keys</strong>, better scaling properties and generally lower costs. The
- * use of {@code long} keys allows for faster compares and lower memory costs. The Map provides
- * identical correctness properties as ConcurrentHashMap. All operations are non-blocking and
- * multi-thread safe, including all update operations. {@link NonBlockingHashMapLong} scales
- * substatially better than {@link java.util.concurrent.ConcurrentHashMap} for high update rates,
- * even with a large concurrency factor. Scaling is linear up to 768 CPUs on a 768-CPU Azul box,
- * even with 100% updates or 100% reads or any fraction in-between. Linear scaling up to all cpus
- * has been observed on a 32-way Sun US2 box, 32-way Sun Niagra box, 8-way Intel box and a 4-way
- * Power box.
- *
- * <p><strong>The main benefit of this class</strong> over using plain {@link
- * io.rsocket.util.NonBlockingHashMap} with {@link Long} keys is that it avoids the auto-boxing and
- * unboxing costs. Since auto-boxing is <em>automatic</em>, it is easy to accidentally cause
- * auto-boxing and negate the space and speed benefits.
- *
- * <p>This class obeys the same functional specification as {@link Hashtable}, and includes versions
- * of methods corresponding to each method of <tt>Hashtable</tt>. However, even though all
- * operations are thread-safe, operations do <em>not</em> entail locking and there is <em>not</em>
- * any support for locking the entire table in a way that prevents all access. This class is fully
- * interoperable with <tt>Hashtable</tt> in programs that rely on its thread safety but not on its
- * synchronization details.
- *
- * <p>Operations (including <tt>put</tt>) generally do not block, so may overlap with other update
- * operations (including other <tt>puts</tt> and <tt>removes</tt>). Retrievals reflect the results
- * of the most recently <em>completed</em> update operations holding upon their onset. For aggregate
- * operations such as <tt>putAll</tt>, concurrent retrievals may reflect insertion or removal of
- * only some entries. Similarly, Iterators and Enumerations return elements reflecting the state of
- * the hash table at some point at or since the creation of the iterator/enumeration. They do
- * <em>not</em> throw {@link ConcurrentModificationException}. However, iterators are designed to be
- * used by only one thread at a time.
- *
- * <p>Very full tables, or tables with high reprobe rates may trigger an internal resize operation
- * to move into a larger table. Resizing is not terribly expensive, but it is not free either;
- * during resize operations table throughput may drop somewhat. All threads that visit the table
- * during a resize will 'help' the resizing but will still be allowed to complete their operation
- * before the resize is finished (i.e., a simple 'get' operation on a million-entry table undergoing
- * resizing will not need to block until the entire million entries are copied).
- *
- * <p>This class and its views and iterators implement all of the <em>optional</em> methods of the
- * {@link Map} and {@link Iterator} interfaces.
- *
- * <p>Like {@link Hashtable} but unlike {@link HashMap}, this class does <em>not</em> allow
- * <tt>null</tt> to be used as a value.

Subject: [PATCH 304/824] Introduce JUnit 5 (#478)

This change introduces JUnit 5 to the build.  It enables JUnit 5 support in
Gradle and adds the required dependencies to write JUnit 5 types.  The change
does not remove the JUnit 4 dependencies yet, as the tests have not been
converted.

Subject: [PATCH 305/824] Exceptions Documentation and Testing (#479)

This change adds Javadocs and tests to the exception hierarchy in rsocket-
core.  This change introduces the first JUnit 5 tests (and a fancy test
interface!) as well as using AssertJ to make the assertions more fluent and
understandable.

Subject: [PATCH 306/824] Travis Updates (#482)

This change makes some updates to the Travis configuration.  The updates are
mainly to update to modern Travis configuration requirements as some of the
configuration had been superseded by changes to defaults, and updates to
Travis itself.  This change also adds a build for Java 9.

Subject: [PATCH 307/824] Disable Java 9 Build (#483)

This change disables the Java 9 build because in some circumstances the
Javadocs for the Aeron transport are failing.  This change should be reverted
once this has been sorted out in that code.

Subject: [PATCH 308/824] Fragmentation (#481)

* Alternate Framing Abstraction

This change introduces a framing package that contains strongly typed
representations of all of the RSocket frame types.  These representations are
introduced as a separate abstraction because they specifically remove the
frame length and stream id that are an optional, transport-layer concern. This
allows will allow the main body of the code to be gradually moved over to an
implementation that only deals with the logical frame types, and pushes the
decoration of the frames with frame length and/or stream id down to the
transport layer.  Note that no implementation has been converted over; this is
just the prework to have an the frame types ready for migration.

These frame type representations are all implemented using the Flyweight
pattern (i.e. use the Netty Recycler) and preserve the zero-copy nature of the
existing frame representation.  These implementations have consistent and
symmetric management of ByteBuf retain and release lifecycle, in addition to
well documented and proper nullability enforced APIs, specific to each frame
type. Each implementation is also tested against raw binary representations to
ensure the strictest specification compliance.

Finally, improvements were made to testing with regards to configurable test
logging, an AssertJ ByteBuf Representation for visual comparison on test
failure, and other conveniences.

* Improvements to Fragmentation and Reassembly

This change improves the implementation and test coverage of the fragmentation
and reassembly functionality.  The fragmentation functionality now support all
frame types (previously, only the PAYLOAD frame could be fragmented) and
ensures that a fragmentation and reassembly roundtrip results in an identical
frame.

The implementations of the fragmentation and reassembly functionality has been
implemented on top of the new framing abstraction for testability and to start
moving off of the abstraction that leaks frame lengths and stream ids.  Note
that the implementation of DuplexConnection *does not* move to the new framing
abstraction.  As this interface is not yet migrated, the
FragmentationDuplexConnection is responsible for translating back and forth
between the old abstraction and the new one.  This has an implication that
overhead will increase (although minimally because of zero-copy data and the
use of Flyweights) temporarily during the migration to the new abstraction.
Once that abstraction has been adopted everywhere, the translation will be
removed, and the overheard will go back to it's current levels.

Subject: [PATCH 309/824] Migration of Spectator to Micrometer (#486)

This change migrates the metrics-gathering project from using Spectator to
using Micrometer (https://micrometer.io).  This change fully moves both the
DuplexConnectionInterceptor and RSocketInterceptor to a Micrometer-based
implementation, changing some of the metric names.  The metric name changes
were made at the advice of the project lead of Micrometer in order to get the
most useful (and compatible) metrics and dimensions for monitoring an RSocket-
based system.

As part of writing the tests, some necessary changes were detected in the
framing abstraction.  These changes are included in this.

[resolves #434]

Subject: [PATCH 310/824] Fix Reference Count Leak (#488)

Previously, there were a couple of frames that converted Strings to ByteBufs
automatically as part of construction.  Those frames though, retained any
ByteBufs passed into them so that they could be released by the creators as
necessary.  Since the automatic construction was not doing this release on the
String-based ByteBufs, there was a minor leak of references.  This change
updates those locations to release the String-based ByteBufs and accurately
account for their retention and release.

Subject: [PATCH 311/824] Local Transport Improvements (#489)

This change makes general improvements to the Local Transport.  It updates the
code to make it better documented and tested.  In addition it introduces the
new TransportTest, a JUnit 5 way of testing uniformly across all of the
transport implementations.

Subject: [PATCH 317/824] Bintray Publish Version (#494)

Previously, an update to the build system forgot to include a flag to the
Bintray publication of tags that used the tag value as the version being
published.  This change updates that Travis script to fix this oversight.

In addition, a minor change was made to the Bintray configuration to match the
tagging scheme used by the project.

Subject: [PATCH 320/824] Extract Project Version

Previously the project version in the build was explicitly specified within
the build script itself.  This way of specifying the project version makes the
value non-overrideable from the command line.  This change moves that value to
the gradle.properties file where it becomes a "normal" property, overridable
using the standard -P syntax.

release to test against, this didn't work on the first try.  The first change
required a move of the bintray configuration from the top-level project to
each subproject that would be published.  Unlike before, this is now a subset
of projects excluding things like the integration tests.  Second, this change
finishes improvements to the Maven POM in order to meet the Maven Central
requirements for publication.  Specifically three developers were added to the
POMs in order for Sonatype to reach them if necessary.

Subject: [PATCH 322/824] Maven Dependency Improvements

Previously, an update the build system resulted in the Maven dependencies
being aggressively calculated, before each project add dependencies to itself.
This change updates the ordering of this calculation such that it happens
after each project configures itself.  In addition, this change goes through
each project and ensures that the dependencies are scoped appropriately in
order to achieve the a minimal and accurate Maven POM.

Subject: [PATCH 325/824] Always Reassemble Regardless of MTU (#503)

Previously, if a user configured a non-positive (<=0) MTU for fragmentation,
both fragmentation and reassembly were disabled.  Given that a receiver must
always be prepared to reassemble fragmented frames (there is no handshake or
flag that both parties must agree to) requiring fragmentation to enable
reassembly was to strict.  This change updates the fragmenter to handle an MTU
of size 0 as an indicator that there should be no fragmentation, but still
enable reassembly.  The RSocketFactory was also updated to ensure that the
fragmenter is always added, rather than skipping it when the MTU was zero.

[#501]

Subject: [PATCH 326/824] Netty Transport Improvements (#507)

This change makes general improvements to the Netty Transport.  It updates the
code to make it better documented and tested.  In addition it introduces the
new TransportTest, a JUnit 5 way of testing uniformly across all of the
transport implementations.

Subject: [PATCH 327/824] Slow Test Run Configuration (#512)

Currently the TransportTest#requestChannel2_000_000 test (for all transports)
takes a very long time on some systems.  It's a useful test to have, but not
necessarily to run at all times.  This change creates an @SlowTest annotation
that is meta-annotated so that tests will only be enabled if
TEST_SLOW_ENABLED=true has been set.

[resolves #511]

Subject: [PATCH 375/824] perf changes (#552)

* reset to snapshots for next release

* Switching FrameType flags back to bits (#548)

* switching frame type flag back to bits so we don't have to traverse an array when looking up flags

* jmh test


* Added an EMPTY flag


* changes from performance testing for Netty transport, and underlying RSocket core protocol


* removing unused imports



* switched to netty's IntObjectMap

+## Zero Copy
+By default to make RSocket easier to use it copies the incoming Payload. Copying the payload comes at cost to performance
+and latency. If you want to use zero copy you must disable this. To disable copying you must include a `frameDecoder`
+argument in your `RSocketFactory`. This will let you manage the Payload without copying the data from the underlying
+transport. You must free the Payload when you are done with them
+or you will get a memory leak. Used correctly this will increase latency and performance.
+
+### Example Server setup
+```java
+RSocketFactory.receive()
+        // Enable Zero Copy
+        .frameDecoder(Frame::retain)
+        .acceptor(new PingHandler())
+        .transport(TcpServerTransport.create(7878))
+        .start()
+        .block()
+        .onClose()
+        .block();
+```
+
+### Example Client setup
+```java
+Mono<RSocket> client =
+        RSocketFactory.connect()
+            // Enable Zero Copy
+            .frameDecoder(Frame::retain)
+            .transport(TcpClientTransport.create(7878))
+            .start();
+```

Subject: [PATCH 410/824] Resume support (#558)

* Remove keep-alive related code from RSocket Client/Server, and implement
keep-alive support as KeepAliveConnection: this change is due to RSocket
resumption support implies sessions spanning multiple connections,
and each connection liveness should be checked with keep-alives

* RSocket resume support, with implementation of delivering last received positions by keep-alive frames

* move ClientSetup & ServerSetup implementations from RSocketFactory

* add test dependencies

* use better queue for resumed frames cache

limit frames cache size

cleanup

* external resume frames store

* resume store saveFrames streaming support

upstream frames requesting respects both downstream & resume save frames stream requests

* Resumable connection: better distribution of downstream connection requestN among upstream subscribers

* simplify UpstreamFrameSubscriber

* fix concurrency issues

* cleanup

* apply formatter

* reduce log level to debug

* fix frame leak

Subject: [PATCH 415/824] fixes bug with incorrect WS framesize setup. (#610)

* fixes buf with incorrect WS framesize setup.

This PR provides a websocket transport's frame size setup with regards
of current RSocket fragment size.

Current implementation provides the following setup rules:

 * if `mtu` is 0 (means no fragmentation) - then WS frame size is equal to
   maximum default frame size of RSocket frame which is `16_777_215`;
 * if `mtu` is GT > 0 and LT < 65536 (default for WS frame size) then
   the WS frame size will be its the default one (which is `65536`);
 * if `mtu` is GT > 65536 then the WS frame size will be set to
   the specified by that parameter size

Signed-off-by: Oleh Dokuka <shadowgun@i.ua>

* rollbacks commented docs build

* fixes format

Signed-off-by: Oleh Dokuka <shadowgun@i.ua>

* cleanup pollution uses max frame size from  `FrameLengthFlyweight`

Signed-off-by: Oleh Dokuka <shadowgun@i.ua>

* simplifies logic of max frame size setup for ws transport

Subject: [PATCH 416/824] Feature/external httpserver (#612)

* fixes buf with incorrect WS framesize setup.

This PR provides a websocket transport's frame size setup with regards
of current RSocket fragment size.

Current implementation provides the following setup rules:

 * if `mtu` is 0 (means no fragmentation) - then WS frame size is equal to
   maximum default frame size of RSocket frame which is `16_777_215`;
 * if `mtu` is GT > 0 and LT < 65536 (default for WS frame size) then
   the WS frame size will be its the default one (which is `65536`);
 * if `mtu` is GT > 65536 then the WS frame size will be set to
   the specified by that parameter size

Signed-off-by: Oleh Dokuka <shadowgun@i.ua>

* exposes access to connection acceptor (#600)

Subject: [PATCH 417/824] Switch resume position tracking to byte count (#611)

* channel load test

* Revert "General performance improvements (#598)"

This reverts commit f55cf8f2

* use byte-count for frame positions

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* resume token is ByteBuf

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* Keep-alive connection, receiving remote implied position: replace Flux with simple onRemoteImpliedPosition(long) callback

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* better performance with resume on

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* keep alive handler: less allocations

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* remove ResumptionState to reduce allocations

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* remove ResumedFramesCalculator

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* rename ResumeAwareConnection to ResumePositionsConnection

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* ResumableDuplexConnection: use drain-queue for actions

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* tests

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* formatter

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* cleanup: resume token is released in ClientRSocketSession instead of
         RSocketFactory

         KeepAliveConnection: dispose KeepAliveHandler in onClose()

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* reduce allocations

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* resume: fix race between send / release of frames on received implied position from keepalives

replace state enum with constants

remove unnecessary allocation

make cleanup of store on keep-alive optional

formatter

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* remove unintended changes

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* optimize KeepAliveConnection

optimize ResumableDuplexConnection

Subject: [PATCH 434/824] Resume cleanup round (#624)

* add ResumableKeepAlive tests

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* resume in-memory store: switch to Flux.generate

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* Revert "fix issue when long running channels eventually hang under load"

This reverts commit 7c87f6c0

Signed-off-by: Maksym Ostroverkhov <m.ostroverkhov@gmail.com>

* fix issue when long running channels eventually hang. Replace https://github.com/rsocket/rsocket-java/pull/618 as It caused memory leak in event of resumption

Subject: [PATCH 450/824] Well known mime types and Composite metadata
 extension (#635)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Add encodeUnsignedMedium to NumberUtils

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Add WellKnownMimeType enum with String/ID conversions

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Add a flyweight capable of encoding Composite Metadata

The flyweight also exposes a method to decode Composite Metadata to a
Map.

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Move flyweight into metadata package, change decodeToMap to decodeNext

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Add CompositeMetadata interface with factory methods to decode/encode

The API is intended as a readonly way of listing the composite metadata
mime-buffer pairs, as well as accessing metadata pairs by mime type or
index, including the case where a mime type is associated with several
metadata entries (`List<Entry> getAll(String)`)...

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Add first test for CompositeMetadata (decode smoke test)

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Expose incremental decode method that decodes a single metadata entry

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* WellKnownMimeType parsing now avoids exceptions (except null arguments)

Instead has 2 special enums. int parsing allows detection of potentially
legit type that is still unknown to the current implementation, which
could help making it more future-proof.

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* rework encoding / decoding API around Entry, accommodate 3 mime case

Encoding becomes a mirror of decoding, purely based on Entry.

Accommodate 3 flavors of mime type decoding:

 - compressed well known with id matching an enum
 - uncompressed custom string
 - compressed but known as reserved for future use (future proofness)

 The later can be decoded into a special Entry that will allow re
 encoding it and transmitting it to other nodes as it was.

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* No need for a CompositeMetadata interface, single concrete implem

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Expose the CompositeMetadataFlyweight for low-level, simplify API

 - the flyweight deals with low-level encoding/decoding with
 minimal garbage and only uses exceptions in the encoding path
 -- encoding a non-ASCII custom mime type OR
 -- encoding an out of range byte
 - the CompositeMetadata is an _option_ for a higher level
 Iterable-based API, but which instantiates new types

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Remove CompositeMetadata, make Entry child of flyweight

Entry is now the only high-level abstraction, will need a way to
decode into a List<Entry>.

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Add javadoc for CompositeMetadataFlyweight methods

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Switch to a single Entry implementation, remove isPassthrough

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Rename Entry#decodeEntry to #decode, add #decodeAll

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* apply Google-style formatting

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Use precomputed array for WellKnownMimeType.fromId

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Use precomputed Map<String,WellKnownMimeType> for fromMimeType + jmh benchmark to validate perf increase

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Several custom mime metadata header encoding improvements:

 - avoid the use of a CompositeByteBuf
 - length can be safely predicted due to requirement that custom mime
 type be ASCII only
 - still using UTF8 writing and ByteBufUtil.isText(ASCII) to detect
 non-ascii text as:
   - writeAscii would not reject non-ascii chars but replace with `?`
   - ISO-8859 chars (eg. Latin-1) could be considered valid when only
   checking the number of written bytes
  - use of ByteBufUtil.writeUtf8 to simplify encoding the mime into the
  preallocated buffer
 - release the buffer if there is an encoding exception

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Use Unpooled buffers in tests

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Remove Entry, replace with CompositeMetadata Iterator-like abstraction

The CompositeMetadata wraps a ByteBuf and exposes a hasNext/decodeNext
API (reminiscent of the Iterator API) as a facade over the flyweight's
methods.

Each round decodeNext() is correctly invoked, the CompositeMetadata
state is updated and the getters can be used to retrieve decoded entry
components.

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* Add an encode flyweight method that attempts compressing String

This is a qol method that will first check if the String passed can be
mapped to a WellKnownMimeType (and thus compressed to a 1 byte
representation).

* Avoid moving full buffer's readerIndex when slicing entries

This implies that the index from which to decode and slice the next
entry MUST be provided by the user. To that end, we provide a method
to compute the next entry's index, given the pair of ByteBuf slices
returned by decodeMimeAndContentBuffers.

Also renamed that method to decodeMimeAndContentBufferSlices, to make
it more obvious that it produces slices (readerIndex impact and slices
nature are mentioned in the javadoc).

CompositeMetadata now keeps the nextEntryIndex as state and uses that
for hasNext / decodeNext.

* CompositeMetadata as Iterable

Previously, the implementation of CompositeMetadata resulted in a
mutable type that didn't fit in with either imperative (for) or reactive
(fromIterable) iteration strategies.  This change updates the type to
implement Iterable, and return an Iterator that lazily traverses the
ByteBuf.

There are also some improvements to the Flyweight in order to support
this iteration style.

Subject: [PATCH 456/824] Fix CompositeMetadataFlyweight check of ASCII only
 custom mime (#651)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix CompositeMetadataFlyweight check of ASCII only custom mime

This fixes potential false positives in the encodeMetadataHeader
method "ASCII only" check that results in IllegalArgumentException.

The first byte is readable but not actually written when performing
the check, yet we would consider it in `isText` (looking at a random
byte value).

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* add a test for the ascii check bug

Signed-off-by: Simon Baslé <sbasle@pivotal.io>

* forgot googleDataFormat (again)

Subject: [PATCH 459/824] Lease support (#648)

* lease support

* rsocket requester: remove lifecycle, make interactions single subscriber only

* wrap requester rsockets in multi subscription rsocket, except lease case

* pluggable stats

* single subscriber Requester: metadata-push, fnf, request-response requests are lazy;
                             make sure above can be subscribed at most once, and send at most 1 request frame

Subject: [PATCH 478/824] Add SocketAcceptorInterceptor (#676)

* SocketAcceptor applied symmetrically

This commit deprecates the client side
acceptor(BiFunction<ConnectionSetupPayload, RSocket>) and adds support
for SocketAcceptor instead. This makes it possible for a client side
acceptor to be asynchronous too, and allows applying the same acceptor
both client and server side.

Signed-off-by: Rossen Stoyanchev <rstoyanchev@pivotal.io>

* Add SocketAcceptorInteceptor

This commit adds an interceptor for SocketAcceptor. This provides
access to connection setup information and also allows applying
requester and responder interceptors from one place.

Subject: [PATCH 494/824] Build refactoring and fixing published POMs (#696)

* Upgrade to Gradle 5.6.2

Signed-off-by: Brian Clozel <bclozel@pivotal.io>

* Do not publish dependency management with POMs

Prior to this commit, the POMs and BOM produced by this build would also
publish dependency management information for artifacts that are not
provided by RSocket. This is problematic since this would
provide/enforce opinions about unrelated dependencies such as test and
logging dependencies.

This commit configures the dependency-management Gradle plugin to not
publish dependency management information with the generated POMs.

It also uses the java-platform Gradle plugin to produce a proper BOM
that does not contain dependencies, publishes dependency management
information for RSocket artifacts only, and does not provide any scope
opinion about those.

This commit also polishes the main build file and:

* uses the Netty BOM
* upgrades JUnit to its latest version and uses its BOM
* refactors the Gradle build files to avoid duplication

Subject: [PATCH 495/824] Fix Gradle publication configuration (#698)

Prior to this change, the Gradle publication configuration would be
applied to the wrong level of projects (subprojects of subprojects!),
resulting in no artifacts being published to the repository.

This commit updates the JFrog artifactory Gradle plugin version and
fixes the application of the publication configuration to align with
what's been done with artifactory and bintray configurations.

Subject: [PATCH 496/824] Fix artifacts groupId (#699)

Prior to this change, the default groupId "rsocket-java" would be used
for all RSocket artifacts. This commit fixes the group name to
"io.rsocket" for all Gradle subprojects.

This change is reflected in the published POMs and BOM.

+## Usage of JMH tasks
+
+Only execute specific benchmark(s) (wildcards are added before and after):
+```
+../gradlew jmh --include="(BenchmarkPrimary|OtherBench)"
+```
+If you want to specify the wildcards yourself, you can pass the full regexp:
+```
+../gradlew jmh --fullInclude=.*MyBenchmark.*
+```
+
+Specify extra profilers:
+```
+../gradlew jmh --profilers="gc,stack"
+```
+
+Prominent profilers (for full list call `jmhProfilers` task):
+- comp - JitCompilations, tune your iterations
+- stack - which methods used most time
+- gc - print garbage collection stats
+- hs_thr - thread usage
+
+Change report format from JSON to one of [CSV, JSON, NONE, SCSV, TEXT]:
+```
+./gradlew jmh --format=csv
+```
+
+Specify JVM arguments:
+```
+../gradlew jmh --jvmArgs="-Dtest.cluster=local"
+```
+
+Run in verification mode (execute benchmarks with minimum of fork/warmup-/benchmark-iterations):
+```
+../gradlew jmh --verify=true
+```
+
+## Comparing with the baseline
+If you wish you run two sets of benchmarks, one for the current change and another one for the "baseline",
+there is an additional task `jmhBaseline` that will use the latest release:
+```
+../gradlew jmh jmhBaseline --include=MyBenchmark
+```

+/**
+ * A Subscriber implementation that hosts assertion tests for its state and allows asynchronous
+ * cancellation and requesting.
+ *
+ * <p>To create a new instance of {@link AssertSubscriber}, you have the choice between these static
+ * methods:
+ *
+ * <ul>
+ *   <li>{@link AssertSubscriber#create()}: create a new {@link AssertSubscriber} and requests an
+ *       unbounded number of elements.
+ *   <li>{@link AssertSubscriber#create(long)}: create a new {@link AssertSubscriber} and requests
+ *       {@code n} elements (can be 0 if you want no initial demand).
+ * </ul>
+ *
+ * <p>If you are testing asynchronous publishers, don't forget to use one of the {@code await*()}
+ * methods to wait for the data to assert.
+ *
+ * <p>You can extend this class but only the onNext, onError and onComplete can be overridden. You
+ * can call {@link #request(long)} and {@link #cancel()} from any thread or from within the
+ * overridable methods but you should avoid calling the assertXXX methods asynchronously.
+ *
+ * <p>Usage:
+ *
+ * <pre>{@code
+ * AssertSubscriber
+ *   .subscribe(publisher)
+ *   .await()
+ *   .assertValues("ABC", "DEF");
+ * }</pre>
+ *
+ * @param <T> the value type.

Subject: [PATCH 527/824] Reduce top-level package dependencies (#770)

* Reduce top-level package dependencies

This commit extracts interfaces for ClientRSocketFactory,
ServerRSocketFactory, and ConnectionSetupPayload, and moves the
implementations into a sub-package with no references to it from the
top-level package.

This removes a large package cycle with io.rsocket at the center
of everything since it currently contains both high level
abstractions that (accessed by everything), as well as core protocol
implementations classes (accessing everything).

The refactoring is functionally neutral and backwards compatible.

* Remove deprecated methods

Subject: [PATCH 530/824] reduce package cycles (#774)

* Remove package cycle between resume and internal

Move ClientSetup and ServerSetup are closely associated with the
RSocketFactory implementations. Moving them into core where they are
used from breaks a package cycle between resume and internal.

ClientSetup is straight-forward and folds easily into
DefaultClientRSocketFactory.

ConnectionUtil is closely associated with ServerSetup and has been
folded into it.

* Remove package cycle between lease and exceptions

MissingLeaseException is moved to the lease package next to the
contracts it is declared in breaking a cycle between lease and
exceptions. This is an API breakage but I the impact should be
minor (none? the chances of something handling it explicitly) and
hence an acceptable trade-off.

Signed-off-by: Rossen Stoyanchev <rstoyanchev@pivotal.io>

* Add RSocketProtocolException in top-level package

Replaces (now deprecated) RSocketException from the exceptions package
which can lead to cycles (e.g. with frame package).

Other minor refinements:

- error code validation
- shared errorCode() implementation
- error code in toString()
- avoid NPE for null message, it's better to keep the original exception
  and null is allowed by getMessage().

Signed-off-by: Rossen Stoyanchev <rstoyanchev@pivotal.io>

* Deprecate ErrorType

This change deprecates ErrorType as the same constants are already
declared in ErrorFrameFlyweight and there is hierarchy of exceptions
with one exception per error code.

Subject: [PATCH 531/824] RSocketFactory API enhancements (#780)

This commit adds RSocketConnector and RSocketServer (io.rsocket.core) as
replacements for the now deprecated RSocketFactory (io.rsocket).

A key goal for the change is to avoid a class in the top-level package with
references to sub-packages which leads to package cycles, but also an
opportunity to review and improve the API.

Closes gh-778

Signed-off-by: Rossen Stoyanchev <rstoyanchev@pivotal.io>

Subject: [PATCH 534/824] Restore ConnectionSetupPayload as abstract class
 (#785)

Another follow-up fix for commit 0ac54d4b. Changing ConnectionSetupPayload
from abstract class to interface is problematic when framework code
compiled against newer RSocket is used in an application on existing
version.

ConnectionSetupPayload is now an abstract class again but
DefaultConnectionSetupPayload remains in the "core" sub-package to avoid
the package cycle with "frame".

From 3a5a4c240d206db04b11658a3e81e9b9469f2ed8 Mon Sep 17 00:00:00 2001
From: Oleh Dokuka <shadowgun@i.ua>
Date: Fri, 24 Apr 2020 10:47:55 +0300
Subject: [PATCH 542/824] Fixes Payload#hasMetadata to strictly flow the flag
 in frame

This PR ensures that Payload#hasMetadata will have identically value as it was encoded in frame decoded to Payload.
Also, this PR ensures that during the encoding the current behavior of Payload#metadata \ Payload#sliceMetadata which always return a buffer (even though them hasMetadata is false) will not brake encoding process and the result flag in the encoded frame will be mirroring exactly what `Payload#hasMetadata` returned

* fixes behaviour of flight-weights when it gets unreadable buffers

ensures that ByteBufPayload is not accessible anymore when it has been released

Signed-off-by: Oleh Dokuka <shadowgun@i.ua>

* partial

Signed-off-by: Oleh Dokuka <shadowgun@i.ua>

* fixes incorrect request propagation

Initially that issue was hidden because both sides uses limitRate which does prefetch 256 elements in advance so it is almost impossible to track underflow in request

Signed-off-by: Oleh Dokuka <shadowgun@i.ua>

* provides refactoring related to ensuring that hasMetadata is propagated correctly

Right now there was observed a few issues related to that

Payload with no metadata was incorrectly incoded so it results to hasMetadata true on the received side
Also, optimized the API of Flyweights to ensure that we have common things in one place

Signed-off-by: Oleh Dokuka <shadowgun@i.ua>

* fixes failing tests related to changes of initialRequestN

Signed-off-by: Oleh Dokuka <shadowgun@i.ua>

* fixes compilation errors

Signed-off-by: Oleh Dokuka <shadowgun@i.ua>

* uncomment assertions related to proper metadata propagation

Signed-off-by: Oleh Dokuka <shadowgun@i.ua>

* moves payload releasing to codecs

Subject: [PATCH 552/824] provides more `ByteBuf` leaks fixes (#803)

1. Ensures if there goes something during `Payload` to the frame we will not get any memory leaks in the end
2. Fixes `onDiscard` leak which did not work correctly because `actual` subscriber was nulled to early
3. Ensures that we will not have the wrong frame order in case of racing the first `Payload` sending and cancel. Also, it moves `onDiscard` hook to the very bottom in case of `requestChannel` to ensure the first payload is not leaked
4. Enables a set of tests that ensures that #757 and #733 are fully or partially fixed.

- * A client-side interface to simplify interactions with the {@link
- * io.rsocket.core.RSocketConnector}. This interface represents logical communication over {@link
- * RSocket}, hiding the complexity of {@code Mono<RSocket>} resolution. Also, in opposite to {@link
- * RSocket} , {@link RSocketClient} supports multi-subscription on the same {@link Publisher} from
- * the interaction in the way of accepting input as {@link Publisher} like {@link Mono} or {@link
- * Flux} Despite, {@link RSocket} interface, {@link RSocketClient} does not coupled with a single
- * connection, hence disposal of the {@link #source()} {@link RSocket} will affect the {@link
- * RSocketClient} it selves. In such a case, a new request will cause automatic reconnection if
- * necessary.
+ * Contract to perform RSocket requests from client to server, transparently connecting and ensuring
+ * a single, shared connection to make requests with.
+ *
+ * <p>{@code RSocketClient} contains a {@code Mono<RSocket>} {@link #source() source}. It uses it to
+ * obtain a live, shared {@link RSocket} connection on the first request and on subsequent requests
+ * if the connection is lost. This eliminates the need to obtain a connection first, and makes it
+ * easy to pass a single {@code RSocketClient} to use from multiple places.
+ *
+ * <p>Request methods of {@code RSocketClient} allow multiple subscriptions with each subscription
+ * performing a new request. Therefore request methods accept {@code Mono<Payload>} rather than
+ * {@code Payload} as on {@link RSocket}. By contrast, {@link RSocket} request methods cannot be
+ * subscribed to more than once.

Subject: [PATCH 594/824] ensures lease is used exactly on request frame
 sending (#855)

This PR ensures:

1. Lease is used on request frame sending
2. Lease is not used if a stream was not subscribed nor requested
3. Lease is not used if a stream was subscribed but then canceled before request frame has been sent

 /**
- * A client-side interface to simplify interactions with the {@link
- * io.rsocket.core.RSocketConnector}. This interface represents logical communication over {@link
- * RSocket}, hiding the complexity of {@code Mono<RSocket>} resolution. Also, in opposite to {@link
- * RSocket} , {@link RSocketClient} supports multi-subscription on the same {@link Publisher} from
- * the interaction in the way of accepting input as {@link Publisher} like {@link Mono} or {@link
- * Flux} Despite, {@link RSocket} interface, {@link RSocketClient} does not coupled with a single
- * connection, hence disposal of the {@link #source()} {@link RSocket} will affect the {@link
- * RSocketClient} it selves. In such a case, a new request will cause automatic reconnection if
- * necessary.
+ * Contract to perform RSocket requests from client to server, transparently connecting and ensuring
+ * a single, shared connection to make requests with.
+ *
+ * <p>{@code RSocketClient} contains a {@code Mono<RSocket>} {@link #source() source}. It uses it to
+ * obtain a live, shared {@link RSocket} connection on the first request and on subsequent requests
+ * if the connection is lost. This eliminates the need to obtain a connection first, and makes it
+ * easy to pass a single {@code RSocketClient} to use from multiple places.
+ *
+ * <p>Request methods of {@code RSocketClient} allow multiple subscriptions with each subscription
+ * performing a new request. Therefore request methods accept {@code Mono<Payload>} rather than
+ * {@code Payload} as on {@link RSocket}. By contrast, {@link RSocket} request methods cannot be
+ * subscribed to more than once.
+ *
+ * <p>Use {@link io.rsocket.core.RSocketConnector RSocketConnector} to create a client:
+ *
+ * <pre class="code">{@code
+ * RSocketClient client =
+ *         RSocketConnector.create()
+ *                 .metadataMimeType("message/x.rsocket.composite-metadata.v0")
+ *                 .dataMimeType("application/cbor")
+ *                 .toRSocketClient(TcpClientTransport.create("localhost", 7000));
+ * }</pre>
+ *
+ * <p>Use the {@link io.rsocket.core.RSocketConnector#reconnect(Retry) RSocketConnector#reconnect}
+ * method to configure the retry logic to use whenever a shared {@code RSocket} connection needs to
+ * be obtained:
+ *
+ * <pre class="code">{@code
+ * RSocketClient client =
+ *         RSocketConnector.create()
+ *                 .metadataMimeType("message/x.rsocket.composite-metadata.v0")
+ *                 .dataMimeType("application/cbor")
+ *                 .reconnect(Retry.fixedDelay(3, Duration.ofSeconds(1)))
+ *                 .toRSocketClient(TcpClientTransport.create("localhost", 7000));

Subject: [PATCH 619/824] fixes `DefaultPayload.create(ByteBuf, ByteBuf)` to
 release params (#886)

This PR makes `DefaultPayload.create(ByteBuf, ByteBuf)` behaves consistent with `ByteBufPayload.create(ByteBuf, ByteBuf)` method.

Please note, both methods do not require a user to take any further actions on releasing provided data and metadata `ByteBuf`s. This is a responsibility of the Payload to do so immediately (in the case of `DefaultPayload`) or later, upon the release faze (in case of `ByteBufPayload`)

Subject: [PATCH 626/824] improves ref-counting by eliminating redundant
 retain/release (#902)

improves ref counting and performance subsequently by eliminating redundant retain on the transport level hence we do not need to release this frame on the RSocketRequester/RSocketResponder level anymore

Fixes all duplex connections to follow that strategy

- * Contract to perform RSocket requests from client to server, transparently connecting and ensuring

- *
- * <p>{@code RSocketClient} contains a {@code Mono<RSocket>} {@link #source() source}. It uses it to
- * obtain a live, shared {@link RSocket} connection on the first request and on subsequent requests
- * if the connection is lost. This eliminates the need to obtain a connection first, and makes it
- * easy to pass a single {@code RSocketClient} to use from multiple places.
- *
- * <p>Request methods of {@code RSocketClient} allow multiple subscriptions with each subscription
- * performing a new request. Therefore request methods accept {@code Mono<Payload>} rather than
- * {@code Payload} as on {@link RSocket}. By contrast, {@link RSocket} request methods cannot be
- * subscribed to more than once.
- *

+/**
+ * Contract for performing RSocket requests.
+ *
+ * <p>{@link RSocketClient} differs from {@link RSocket} in a number of ways:
+ *
+ * <ul>
+ *   <li>{@code RSocket} represents a "live" connection that is transient and needs to be obtained
+ *       typically from a {@code Mono<RSocket>} source via {@code flatMap} or block. By contrast,
+ *       {@code RSocketClient} is a higher level layer that contains such a {@link #source() source}
+ *       of connections and transparently obtains and re-obtains a shared connection as needed when
+ *       requests are made concurrently. That means an {@code RSocketClient} can simply be created
+ *       once, even before a connection is established, and shared as a singleton across multiple
+ *       places as you would with any other client.
+ *   <li>For request input {@code RSocket} accepts an instance of {@code Payload} and does not allow
+ *       more than one subscription per request because there is no way to safely re-use that input.
+ *       By contrast {@code RSocketClient} accepts {@code Publisher<Payload>} and allow
+ *       re-subscribing which repeats the request.
+ *   <li>{@code RSocket} can be used for sending and it can also be implemented for receiving. By
+ *       contrast {@code RSocketClient} is used only for sending, typically from the client side
+ *       which allows obtaining and re-obtaining connections from a source as needed. However it can
+ *       also be used from the server side by {@link #from(RSocket) wrapping} the "live" {@code
+ *       RSocket} for a given connection.
+ * </ul>
+ *
+ * <p>The example below shows how to create an {@code RSocketClient}:
+ *
+ * <pre class="code">{@code
+ * Mono<RSocket> source =
+ *         RSocketConnector.create()
+ *                 .metadataMimeType("message/x.rsocket.composite-metadata.v0")
+ *                 .dataMimeType("application/cbor")
+ *                 .connect(TcpClientTransport.create("localhost", 7000));
+ *
+ * RSocketClient client = RSocketClient.from(source);
+ * }</pre>
+ *
+ * <p>The below configures retry logic to use when a shared {@code RSocket} connection is obtained:
+ *
+ * <pre class="code">{@code
+ * Mono<RSocket> source =
+ *         RSocketConnector.create()
+ *                 .metadataMimeType("message/x.rsocket.composite-metadata.v0")
+ *                 .dataMimeType("application/cbor")
+ *                 .reconnect(Retry.fixedDelay(3, Duration.ofSeconds(1)))
+ *                 .connect(TcpClientTransport.create("localhost", 7000));

From 02833732d0dbd97dad30b4ff32831b0c9cc3fe8b Mon Sep 17 00:00:00 2001
From: Oleh Dokuka <oleh.dokuka@icloud.com>
Date: Mon, 24 May 2021 23:36:56 +0300
Subject: [PATCH 751/824] reworks and improves Resumability impl

this includes:
  * rework of InMemoryResumableFramesStore and improvement in its tests coverage
  * improvements in Client/Server resume Session and ensuring that if connection is rejected for any reasons - it is fully closed on both outbound and inbound ends (This fix is needed for LocalDuplexConnection scenario which may be in unterminated state if it will not be subscribed on the inbound)
  * enabling resumability tests for LocalTransport
  * improvements in logging
  * general cleanups and polishing

Subject: [PATCH 752/824] improves LocalDuplexConnection (#onClose notification
 + ByteBufs releases)

At the moment, the onClose hook has no "wait until cleaned" logic, which leads to unpredicted behaviors when used with resumability or others scenarios where we need to wait until all the queues are cleaned and there are no other resources in use (e.g. ByteBufs). For that porpuse, this commit adds onFinalizeHook to the UnboundedProcessor so we can now listen when the UnboundedProcessor is finalized and only after that send the onClose signal

Subject: [PATCH 754/824] ensures no modifications during iteration

since Processor/Subscription termination with `cancel` or `onError` leads to the following self-removal logic, it can happen that collection concurrent modification exception may appear. To avoid so we can copy all the entries and by doing so avoid any subsequent problems

-##  Gradle start up script for UN*X
-##
+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

Subject: [PATCH 814/824] update versions and fixes memleak in
 UnboundedProcessor (#1106)

This PR updates dependencies and makes minor modifications to UnboundedProcessor due to repeating failures of UnboundedProcessorJCStreassTest, which started reproducing some unspotted issues.

Motivation:

UnboundedProcessor is a critical component in the RSocket-Java ecosystem and must work properly. After analysis of its internal state machine, it was spotted that sometimes:

The request may not be delivered due to natural concurrency
The terminal signal may not be delivered since it checks for demand which might be consumed already (due to natural concurrency)
The final value could be delivered violating reactive-streams spec
Modifications:

This PR adds a minimal set of changes, preserving old implementation but eliminating the mentioned bugs
