It uses CFStream so we get this for *free* 17 | - Uses NSStream/CFNetworking. Earlier implementations used ``dispatch_io``, 18 | however, this proved to be make TLS nearly impossible. Also I wanted this to 19 | work in iOS 4.x. (SocketRocket only supports 5.0 and above now) 20 | - Uses ARC. It uses the 4.0 compatible subset (no weak refs). 21 | - Seems to perform quite well 22 | - Parallel architecture. Most of the work is done in background worker queues. 23 | - Delegate-based. Had older versions that could use blocks too, but I felt it 24 | didn't blend well with retain cycles and just objective C in general. 25 | 26 | Changes 27 | ------- 28 | 29 | v0.3.1-beta2 - 2013-01-12 30 | ````````````````````````` 31 | 32 | - Stability fix for ``closeWithCode:reason:`` (Thanks @michaelpetrov!) 33 | - Actually clean up the NSStreams and remove them from their runloops 34 | - ``_SRRunLoopThread``'s ``main`` wasn't correctly wrapped with 35 | ``@autoreleasepool`` 36 | 37 | v0.3.1-beta1 - 2013-01-12 38 | ````````````````````````` 39 | 40 | - Cleaned up GCD so OS_OBJECT_USE_OBJC_RETAIN_RELEASE is optional 41 | - Removed deprecated ``dispatch_get_current_queue`` in favor of ``dispatch_queue_set_specific`` and ``dispatch_get_specific`` 42 | - Dropping support for iOS 4.0 (it may still work) 43 | 44 | 45 | Installing (iOS) 46 | ---------------- 47 | There's a few options. Choose one, or just figure it out 48 | 49 | - You can copy all the files in the SocketRocket group into your app. 50 | - Include SocketRocket as a subproject and use libSocketRocket 51 | 52 | If you do this, you must add -ObjC to your "other linker flags" option 53 | 54 | - For OS X you will have to repackage make a .framework target. I will take 55 | contributions. Message me if you are interested. 56 | 57 | 58 | Depending on how you configure your project you may need to ``#import`` either 59 | ```` or ``"SRWebSocket.h"`` 60 | 61 | Framework Dependencies 62 | `````````````````````` 63 | Your .app must be linked against the following frameworks/dylibs 64 | 65 | - libicucore.dylib 66 | - CFNetwork.framework 67 | - Security.framework 68 | - Foundation.framework 69 | 70 | Installing (OS X) 71 | ----------------- 72 | SocketRocket now has (64-bit only) OS X support. ``SocketRocket.framework`` 73 | inside Xcode project is for OS X only. It should be identical in function aside 74 | from the unicode validation. ICU isn't shipped with OS X which is what the 75 | original implementation used for unicode validation. The workaround is much 76 | more rudimentary and less robust. 77 | 78 | 1. Add SocketRocket.xcodeproj as either a subproject of your app or in your workspace. 79 | 2. Add ``SocketRocket.framework`` to the link libraries 80 | 3. If you don't have a "copy files" step for ``Framework``, create one 81 | 4. Add ``SocketRocket.framework`` to the "copy files" step. 82 | 83 | API 84 | --- 85 | The classes 86 | 87 | ``SRWebSocket`` 88 | ``````````````` 89 | The Web Socket. 90 | 91 | .. note:: ``SRWebSocket`` will retain itself between ``-(void)open`` and when it 92 | closes, errors, or fails. This is similar to how ``NSURLConnection`` behaves. 93 | (unlike ``NSURLConnection``, ``SRWebSocket`` won't retain the delegate) 94 | 95 | What you need to know 96 | 97 | .. code-block:: objective-c 98 | 99 | @interface SRWebSocket : NSObject 100 | 101 | // Make it with this 102 | - (id)initWithURLRequest:(NSURLRequest *)request; 103 | 104 | // Set this before opening 105 | @property (nonatomic, assign) id delegate; 106 | 107 | - (void)open; 108 | 109 | // Close it with this 110 | - (void)close; 111 | 112 | // Send a UTF8 String or Data 113 | - (void)send:(id)data; 114 | 115 | @end 116 | 117 | ``SRWebSocketDelegate`` 118 | ``````````````````````` 119 | You implement this 120 | 121 | .. code-block:: objective-c 122 | 123 | @protocol SRWebSocketDelegate 124 | 125 | - (void)webSocket:(SRWebSocket *)webSocket didReceiveMessage:(id)message; 126 | 127 | @optional 128 | 129 | - (void)webSocketDidOpen:(SRWebSocket *)webSocket; 130 | - (void)webSocket:(SRWebSocket *)webSocket didFailWithError:(NSError *)error; 131 | - (void)webSocket:(SRWebSocket *)webSocket didCloseWithCode:(NSInteger)code reason:(NSString *)reason wasClean:(BOOL)wasClean; 132 | 133 | @end 134 | 135 | Known Issues/Server Todo's 136 | -------------------------- 137 | - Needs auth delegates (like in NSURLConnection) 138 | - Move the streams off the main runloop (most of the work is backgrounded uses 139 | GCD, but I just haven't gotten around to moving it off the main loop since I 140 | converted it from dispatch_io) 141 | - Re-implement server. I removed an existing implementation as well because it 142 | wasn't being used and I wasn't super happy with the interface. Will revisit 143 | this. 144 | - Separate framer and client logic. This will make it nicer when having a 145 | server. 146 | 147 | Testing 148 | ------- 149 | Included are setup scripts for the python testing environment. It comes 150 | packaged with vitualenv so all the dependencies are installed in userland. 151 | 152 | To run the short test from the command line, run:: 153 | 154 | make test 155 | 156 | To run all the tests, run:: 157 | 158 | make test_all 159 | 160 | The short tests don't include the performance tests. (the test harness is 161 | actually the bottleneck, not SocketRocket). 162 | 163 | The first time this is run, it may take a while to install the dependencies. It 164 | will be smooth sailing after that. After the test runs the makefile will open 165 | the results page in your browser. If nothing comes up, you failed. Working on 166 | making this interface a bit nicer. 167 | 168 | To run from the app, choose the ``SocketRocket`` target and run the test action 169 | (``cmd+u``). It runs the same thing, but makes it easier to debug. There is 170 | some serious pre/post hooks in the Test action. You can edit it to customize 171 | behavior. 172 | 173 | .. note:: Xcode only up to version 4.4 is currently supported for the test 174 | harness 175 | 176 | TestChat Demo Application 177 | ------------------------- 178 | SocketRocket includes a demo app, TestChat. It will "chat" with a listening 179 | websocket on port 9900. 180 | 181 | It's a simple project. Uses storyboard. Storyboard is sweet. 182 | 183 | 184 | TestChat Server 185 | ``````````````` 186 | We've included a small server for the chat app. It has a simple function. 187 | It will take a message and broadcast it to all other connected clients. 188 | 189 | We have to get some dependencies. We also want to reuse the virtualenv we made 190 | when we ran the tests. If you haven't run the tests yet, go into the 191 | SocketRocket root directory and type:: 192 | 193 | make test 194 | 195 | This will set up your `virtualenv `_. 196 | Now, in your terminal:: 197 | 198 | source .env/bin/activate 199 | pip install git+https://github.com/tornadoweb/tornado.git 200 | 201 | In the same terminal session, start the chatroom server:: 202 | 203 | python TestChatServer/py/chatroom.py 204 | 205 | There's also a Go implementation (with the latest weekly) where you can:: 206 | 207 | cd TestChatServer/go 208 | go run chatroom.go 209 | 210 | Chatting 211 | ```````` 212 | Now, start TestChat.app (just run the target in the Xcode project). If you had 213 | it started already you can hit the refresh button to reconnect. It should say 214 | "Connected!" on top. 215 | 216 | To talk with the app, open up your browser to `http://localhost:9000 `_ and 217 | start chatting. 218 | 219 | 220 | WebSocket Server Implementation Recommendations 221 | ----------------------------------------------- 222 | SocketRocket has been used with the following libraries: 223 | 224 | - `Tornado `_ 225 | - Go's `WebSocket package `_ or Gorilla's `version `_ 226 | - `Autobahn `_ (using its fuzzing 227 | client) 228 | 229 | The Tornado one is dirt simple and works like a charm. (`IPython notebook 230 | `_ uses it 231 | too). It's much easier to configure handlers and routes than in 232 | Autobahn/twisted. 233 | 234 | As far as Go's goes, it works in my limited testing. I much prefer go's 235 | concurrency model as well. Try it! You may like it. 236 | It could use some more control over things such as pings, etc., but I 237 | am sure it will come in time. 238 | 239 | Autobahn is a great test suite. The Python server code is good, and conforms 240 | well (obviously). However for me, twisted would be a deal-breaker for writing 241 | something new. I find it a bit too complex and heavy for a simple service. If 242 | you are already using twisted though, Autobahn is probably for you. 243 | 244 | Contributing 245 | ------------ 246 | We’re glad you’re interested in SocketRocket, and we’d love to see where you take it.
