Ray, What other web scripting languages have to worry about race conditions? As far as I remember, ASP and PHP do not suffer from this problem. So if this type of functionality (not having to lock shared scope variables, which is really anti-functionality) is attainable, how come CFMX was not programmed in this way? After all it IS a new product. Also, you didn't answer the main question: why does the article imply that locking is not required, but then imply you "might" have variable corruption issues? Either you have to lock or not -- how can there be an in-between when developer's need a concrete way to work with these types of variables so they can build robust apps?
I'm not trying to be difficult, it just seems like this article says one thing and then totally refutes it at the same time! :) Andy > -----Original Message----- > From: Raymond Camden [mailto:jedimaster@;macromedia.com] > Sent: Friday, November 01, 2002 11:47 AM > To: CF-Talk > Subject: RE: Understanding Locking In CFMX > > > Maybe I'm wrong - but other languages DO have to worry about race > conditions.
