Hi
Thanks in advance
Whats mean:
expensive_func ? and
mycache = cache.get_cache('my_function') ==> my_function ?
I tried in lib/app_globals.py
self.expensive_func = "myDinamicDir" ??? or a link to a new Function?
I read about config and app_globals
"Because the app_globals object is persistent across requests, it can
be modified by any thread. This means it is possible that a value
attached to app_globals might be different at the start of a request
than at the end if another thread has changed its value in between.
... if you aren’t used to working in multithreaded environments"
How I want multithreaded environment Should I use Template Context c Global?
"...The c global is reset on each request so that you don’t need to
worry about a controller still having old values set from a previous
request..."
My target isnt cache itself but store my session where I want. Beaker
control Sessions dir with data_dir too and I need custom to fit my
needs.
So I read
/usr/lib/python2.6/site-packages/Beaker-1.5.3-py2.6.egg/beaker/container.py
class FileNamespaceManager(OpenResourceNamespaceManager):
So I could just custom this class but my fraid is "multithreaded"
trouble so What Pylons Team recommend?
I know isnt recommend custom a class inside a package but is a easy
solution. I not very familiar with all python concepts. Could someone
recommend if I need apply some Design Partner to resolve this issue?
Best Regards
Mario
