Hi!
I use ZODB3. I want to pickle parts
of my database and import it on a different system.
Since, as far as I know, ZODB uses the __getstate__ method
for pickling the objects.
For my export, I want to ignore some parts of my objects.
If I will change __getstate__ I am in trouble because Zope
uses it.
Using a global variable in __getstate__ to see if I am in
"zope-getstate" or "my-export getstate" mode is dangerous, since
the application is multithreaded.
I thought about using a dict which holds the variable for each thread.
What other solutions are possible?
Example:
class MyClass:
def __init__(self, root)
self.root=root
I want to ignore the reference to root, since I want to import the
object into a new root.
