Hi
Question is, what is view_name supposed to do during
invalidation?
In OFS.Cache.Cacheable we have:
def ZCacheable_invalidate(self, view_name='', REQUEST=None):
'''Called after a cacheable object is edited. Causes all
cache entries that apply to the view_name to be removed.
Returns a status message.
'''
c = self.ZCacheable_getCache()
if c is not None:
ob, view_name = self.ZCacheable_getObAndView(view_name)
try:
message = c.ZCache_invalidate(ob)
(...)
and:
def ZCacheable_getObAndView(self, view_name):
(...)
ob = self
if not view_name and self.ZCacheable_isAMethod():
# This is a ZClass method.
ob = aq_parent(aq_inner(self))
if isCacheable(ob):
view_name = self.getId()
else:
# Both the parent and the child have to be
# cacheable.
ob = self
return ob, view_name
As far as I understand this, 'view_name' is useless here, and
invalidation always occurs for all cache keys associated with object
'ob'. But this is not what docstring for ZCacheable_invalidate says.
Seems strange but maybe I've missed something here?
