i'm trying to form a patch that will result in a method "_before_commit()"
being called on each modified object in a transaction (if that method
exists of course) right before commit.
main sense is to automate/delay (re)cataloging.
first i looked at the Transaction class, as there have been heavy
modifications to it from zodb 3.2 to 3.4 i looked around again and
figured the best place to add the hack for testing was
lib/python/ZODB/Connection.py - i tried to add the following code
snippet to the very beginning of tpc_begin():
for obj in self._registered_objects:
hook = getattr(obj, '_before_commit', None)
if hook is not None: hook()
the effect is that the method gets called correctly on each modified
object (hurray!), but i have another problem:
my _before_index() method is very simple at the moment:
...it simply calls reindex_object, inherited from CatalogPathAwareness.
and that does nothing. why? hmm - seems like the object cannot acquire
here's my folder structure for instances:
the catalog is here:
and each of them failed. and here i don't know the answer.
something wrong with my approach? hope somebody can help.
regards, juergen herrmann
