|
|
* This seems is less than ideal-- we should determine if it's a token
|
|
|
|
* object or a session object, and use the appropriate arena.
|
|
|
|
* But that duplicates logic in nssCKFWObject_IsTokenObject.
|
|
|
|
* Also we should lookup the real session the object was created on
|
|
|
|
* if the object was a session object... however this code is actually
|
|
|
|
* correct because nssCKFWObject_Create will return a cached version of
|
|
|
|
* the object from it's hash. This is necessary because 1) we don't want
|
|
|
|
* to create an arena style leak (where our arena grows with every search),
|
|
|
|
* and 2) we want the same object to always have the same ID. This means
|
|
|
|
* the only case the nssCKFWObject_Create() will need the objArena and the
|
|
|
|
* Session is in the case of token objects (session objects should already
|
|
|
|
* exist in the cache from their initial creation). So this code is correct,
|
|
|
|
* but it depends on nssCKFWObject_Create caching all objects.
