Re: cvs: php4 / NEWS /ext/standard dir.c

Heads up to those of you who write resource-based modules; If your module follows the MySQL model, and allows omitting the resource handle which will make the various functions use the 'default' or 'active' resource, you must implement the code in the same way the MySQL module implements it in order for it to work properly. The rule is very simple - you should increase the reference count for the 'active' resource when it becomes the active resource (as it's pointed by another thing), and you should decrease the reference count when it becomes inactive (usually, either in shutdown or when it's replaced by a different active resource; As a matter of fact, the MySQL module seems to forget to release it on shutdown, which is no biggy, but I'll fix that for 4.0.2). If you don't follow that rule - the resource id you return from your function will be either immediately invalid, or may become invalid ahead of time.
