From c872bf0223d55a7271ac98152e6b4e064361736a Mon Sep 17 00:00:00 2001 From: Alexander Blom Date: Mon, 20 Feb 2017 19:08:02 +0000 Subject: [PATCH 001/731] 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. --- .../frame/FrameHeaderFlyweight.java | 164 +++++++++++------- .../frame/RequestFrameFlyweight.java | 5 +- .../frame/SetupFrameFlyweight.java | 5 +- .../frame/FrameHeaderFlyweightTest.java | 102 +++++++++++ .../frame/SetupFrameFlyweightTest.java | 30 ++++ .../tcp/ReactiveSocketLengthCodec.java | 6 +- 6 files changed, 247 insertions(+), 65 deletions(-) create mode 100644 reactivesocket-core/src/test/java/io/reactivesocket/frame/FrameHeaderFlyweightTest.java create mode 100644 reactivesocket-core/src/test/java/io/reactivesocket/frame/SetupFrameFlyweightTest.java diff --git a/reactivesocket-core/src/main/java/io/reactivesocket/frame/FrameHeaderFlyweight.java b/reactivesocket-core/src/main/java/io/reactivesocket/frame/FrameHeaderFlyweight.java index 49e1f3052..43f0044ba 100644 --- a/reactivesocket-core/src/main/java/io/reactivesocket/frame/FrameHeaderFlyweight.java +++ b/reactivesocket-core/src/main/java/io/reactivesocket/frame/FrameHeaderFlyweight.java @@ -43,33 +43,39 @@ private FrameHeaderFlyweight() {} private static final boolean INCLUDE_FRAME_LENGTH = true;

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 ` : This is for the client only, determines what host to connect to + +`--port

    ` : If launching as client, tells it to connect to port `p`, and if launching as server, tells what port to server on + +`--file ` : 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`. + diff --git a/reactivesocket-tck-drivers/build.gradle b/reactivesocket-tck-drivers/build.gradle new file mode 100644 index 000000000..04b6e7657 --- /dev/null +++ b/reactivesocket-tck-drivers/build.gradle @@ -0,0 +1,28 @@ +apply plugin: 'application' +apply plugin: 'java' + +mainClassName = "io.reactivesocket.tckdrivers.main.Main" + +jar { + manifest { + attributes "Main-Class": "$mainClassName" + } + + from { + configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } + } +} + +dependencies { + + compile project(':reactivesocket-core') + compile project(':reactivesocket-client') + compile project(':reactivesocket-transport-netty') + testCompile project(':reactivesocket-test') + compile 'com.fasterxml.jackson.core:jackson-core:2.8.0.rc2' + compile 'com.fasterxml.jackson.core:jackson-databind:2.8.0.rc2' + compile 'org.apache.commons:commons-lang3:3.4' + compile 'io.reactivex:rxnetty-tcp:0.5.2-rc.5' + compile 'io.reactivex.rxjava2:rxjava:2.0.2' + compile 'io.airlift:airline:0.7' +} diff --git a/reactivesocket-tck-drivers/run.sh b/reactivesocket-tck-drivers/run.sh new file mode 100755 index 000000000..62ff4fde9 --- /dev/null +++ b/reactivesocket-tck-drivers/run.sh @@ -0,0 +1,7 @@ +#!/bin/bash + +LATEST_VERSION=$(ls build/libs/reactivesocket-tck-drivers-*-SNAPSHOT.jar | sort -r | head -1) + +echo "running latest version $LATEST_VERSION" + +java -cp "$LATEST_VERSION" io.reactivesocket.tckdrivers.main.Main "$@" diff --git a/reactivesocket-tck-drivers/src/main/java/io/reactivesocket/tckdrivers/client/JavaClientDriver.java b/reactivesocket-tck-drivers/src/main/java/io/reactivesocket/tckdrivers/client/JavaClientDriver.java new file mode 100644 index 000000000..9c2d186f2 --- /dev/null +++ b/reactivesocket-tck-drivers/src/main/java/io/reactivesocket/tckdrivers/client/JavaClientDriver.java @@ -0,0 +1,620 @@ +/* + * Copyright 2016 Facebook, Inc. + *
