Is it possible to flush a path w/ a specific argument from a RAM cache from a Python script?
Here's my situation: I have a script FolderExists() that takes a single "path" argument and, after running an SQL query, returns True or False if the folder path exists or not in the database. Since the database query is relatively expensive, I want to cache its result in RAM. However, if a folder is created (using another Python script in the same Zope instance) I want to flush the cached result for the path (i.e., I don't want to flush all of the cached entries for the FolderExists method if that can be avoided).
Unfortunately no, it's a deficiency of the simple RAMCacheManager: you can't invalidate a key individually, you have to invalidate them all. Changing this is probably not too complex, and is (low) on my TODO list (at position approx. 136 ;)).
