The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

This only works if you have only two calls to OnReceive() happening at once, no
The key here is the BeginReceive call, which tells the .NET socket support to call the OnReceive delegate asynchronously on a thread pool thread when a message is received. In my initial code that has the bug, I was issuing the second BeginReceive call to start receipt of the next message before I'd finished processing the current message. Under high load conditions, this could cause the OnReceive handler to be called recursively. The actual message handling would then be processed in reverse order as the stack unwound.
Member 7931978 wrote:
what guarantee do you have that the "correct" thread will be the next one to acquire the lock?
The lock in this case was protecting the socket connection, so there is no 'correct' thread per se. The .NET socket support can call the asynchronous delegate on any thread it has available. The lock is essentially a critical section.
Software Zen: delete this;
