[Zope] Clearing _v_ attributes

[Pascal Peregrina]

If I do a clearCaches() method that clears _v_ attributes on the object, how
can I make sure it will clear these attributes in all the Zope connections
that may have a cached copy of the object ?

Or do you mean that clearCaches() should do the self._p_changed=1 ?

| Hi,
| 
| To clear some data caching I have made using _v_ attributes on one
| particular object, I would need a way to programmatically clear its _v_
| attributes.
| 
| As far as I understand, _v_ attributes are set per ZODB connection.
| And they are cleared when the object is, for some reason, reloaded from
the
| ZODB to the connection cache.
| 
| As I use the current configuration :
| + ZEO
| + 1 Zope instance with RW connections to ZEO
| + several Zope instances with RO connections to ZEO
| 
| I was wondering if, setting self._p_changed=1 on the object from the Zope
RW
| would work.

No...

Why not just add a clearCaches() method that Does The Right Thing(tm) and
call
that?
