Ok, as promised, a new thread on threading... Perhaps I should begin my question with my perhaps-incorrect understanding of instances. I have always understood an "instance" to be a unique, individual memory-resident copy of an object that contains methods and properties, or functions and attributes, or whatever they be called in your current universe. An "instance" of an "object" would, then, be the result of a call to the object's codebase from within an existing thread, and it's constructor would fire as soon as the CFOBJECT or createObject executed.
I've always assumed that an instance would be intrinsically thread-safe if the underlying engine was also thread-safe. As an object created within a thread, wouldn't it be thread-safe because the thread that created it "owns" that instance? And, in that case, it's THIS scope would be available to all methods within the instance, and whatever non-scoped var you create within a method would be function-local by default? Or, perhaps, we're discussing persistent CFCs, in which case I would have assumed that if you use locks around your code that accesses/modifies the data in your persistent CFC it would mitigate the lack of thread-safety that ANY shared-scope variable. Until now, I've been using this THIS scope A LOT, not VARing any of my method variables, and wrapping CFLOCKS around calls to methods that would alter the data within a session-scope persistent CFC. Have I been doing this wrong? It took me 6 months to get my head around USING CFCs (Easy concept! Murderous implementation!) to begin with, and I still miss the good-old-days of procedural templates... so simple, so straigforward, so... 2-dimensional. But, teach thou me and I shall implement! So, now that I've laid my ignorance out for you all to see, please be gentle? :D Laterz all!
