Re: [ZODB-Dev] Cached object error while upgrading Plone
Hello Martijn, Actually for DirectoryViewSurrogate (see the second paste) that is not the case since it subclasses OFS.Folder.Folder - which is persistent. Alex.

Re: [ZODB-Dev] Cached object error while upgrading Plone
Hello Shane, I think that you're right about the persistent to non-persistent changes and vice-versa. I will try to identify the object that does this. What do you mean by removing add-ons? You mean products? And if I remove my third party products and make the objects which subclass the ATFolder broken then I will not get the necessary upgrades specific to folders right? Thanks for your input, Alex.

And maybe a theory of why this is happening. That kind of thing happens when a class changes from non-persistent to persistent or vice-versa. This may be caused by add-ons. When I do a major Plone upgrade, I first disable all add-ons temporarily and that usually does the trick. If that doesn't work, I suggest you get a list of all your add-ons and ask this question on a Plone list.

Re: [ZODB-Dev] I would like to know if api exists nowadays to get list of all objects which where modified in a transaction ?
Hi, I would interested in this as well. Sometimes debugging becomes difficult for big transactions where multiple different objects are modified. Usually than happens from different parts of the code through subscribers to events. It would be great if this kind of feature existed so you could have an overview of what happens during a transaction. Alex.

Re: [ZODB-Dev] I would like append an indexer with uuid key at root of my ZODB, how can I append an function to commit event to update this uuid catalog ?
Hi Stéphane,
Maybe this will be helpful:
http://www.zodb.org/documentation/articles/ZODB2.html#persistent-aware-types
I think what you are looking for is an OOBTree with the key being your uuid
and the value being the path to your Resources object.
def get_uuid(uuid, context):
resource_path = context.my_btree.get(uuid, None)
if uuid is not None:
return context.unrestrictedTraverse(resource_path)
You can get the path of an object in OFS by calling absolute_url method of
that object.
Hope this helps,
Alex.

I use ZODB to record some Resources.
All my Resources have an uuid field.
All work well but I would like append a BTree to ZODB root object to
index uuid of all my resources.
I would like record to this BTree index only Resources commited to ZODB
database.
How can I connect a function to commit event ?
In this function, how can I found all object modified ?
How can I found all object removed to the database ?
Other question : are there already a package to perform this task ?
The matching package is zope.catalog.
It provides all you need (catalog and indexes) to handle your task.
Objects creations and modifications are followed automatically by several
subscribers as soon as this package is correctly registered.
z3c.catalog and hurry.query packages can be good extensions packages to
look at...
I've already looked zope.catalog and repoze.catalog.
Question : I haven't docid, can I use uuid here ? but it isn't the
feature I want : I would like retrieve my object from uuid.
Do you have an example of code about it ?
More information about my aim :
root (ZODB)
uuid = { uuid_value1: resource_A, uuid_value2: resource_B, ... }
folder_1
resource_A
folder_2
resource_B
I would like this function :
get_by_uuid(uuid_value1)
= return resource_A

Stephane
