Jonathan, Thank you sooo much for your assistance. Here's what ended up working for me:
1. I did update my AsyncSocket class as suggested. Thanks. 2. I determined that my runloop was not functioning as expected using your suggestions. As you said, there is a lot of information here, and although I am well-versed now, it was/is new to me (defending my ignorance). Again, thanks! 3. I used the ThreadWorker class which has a nice technique for keeping the runloop alive while in the worker thread. This is a very well done class that also provides all of the hooks for GUI update, and other niceties. I still have one issue: I am instantiating my class in the worker thread (as required per AsyncSocet docs). When I dealloc my object (which calls the socket.disconnect method), the socket(s) do not disconnect properly, and I end up with a "socket leak". If I do not dealloc, the disconnect operation occurs normally, and it appears that the "garbage collection" autoreleases the object. Is this OK? Seems kinda sloppy. Any suggestions? Best regards, Matt Matthew 1. Are you using the latest AsyncSocket sources? cocoaasyncsocket - Google Code <http://code.google.com/p/cocoaasyncsocket/> 2. AsyncSocket, though very good, is not perfect. I recently subclassed AsyncSocket and encountered a fundamental problem (easily fixed however). There could be unrecognised issues with the threading support as threading AsyncSocket probably hasn't been attempted that much. 3. Are the CFSocket callback functions being called in AsyncSocket.m: - static void MyCFSocketCallback (CFSocketRef sref, CFSocketCallBackType type, CFDataRef address, const void *pData, void *pInfo); - static void MyCFReadStreamCallback (CFReadStreamRef stream, CFStreamEventType type, void *pInfo); - static void MyCFWriteStreamCallback (CFWriteStreamRef stream, CFStreamEventType type, void *pInfo); Cave man debugging techniques should do the trick there. 4. Take a good hard look at AsyncSocket.m - (void)doAcceptWithSocket:(CFSocketNativeHandle)newNative and the delegate method -[theDelegate onSocket:self wantsRunLoopForNewSocket:newSocket]. 5. Use CFRunLoopContainsSource to check that your socket has been successfully added to the correct run loop. Good luck! Jonathan FROM : Matthew Youney DATE : Fri Aug 15 00:45:34 2008 Jonathan, The reason I need to thread is not anything to do with AsyncSocket, which is an excellent library that does not block. I have several time consuming operations that must occur sequentially. These sequences need to run (start/stop) asynchronous of each other, so I want these to run in separate execution threads. The "old school" way that I used to manage multiple asynchronous sequences like this was to use complex state machines, but I am sure that you will agree that separate threads is certainly the way to go. I am just having difficulty getting my head around the run loop in the worker threads. I have also tried the ThreadWorker library, that although has some awesome features, does not let my AsyncSocket objects run properly. And thanks, I appreciate any and all feedback, Matt -----Original Message----- From: cocoa-dev-bounces+matt=youney.<email_removed> [ mailto:cocoa-dev-bounces+matt=youney.<email_removed>]On Behalf Of <email_removed> Sent: Thursday, August 14, 2008 5:04 PM To: <email_removed> Subject: Re: Threading problem using AsyncSocket (Matthew Youney) I don't know about your threading problem but surely the whole point of AsyncSocket is the Async bit. It is designed to attach itself to the runloop and remove the need for blocking sockets etc on threads. I use AsyncSocket extensively within the main thread and it can handle multiple connection without any problem. > Hello list, > This is my first attempt at threading with Cocoa, and I am having > difficu= > lty > with my classes that use AsyncSocket.

Something fundamentally wro= ng? Thanks in advance for any and all assistance.
