Migration to Plone 5.2 - ZODB to py3 - zodbverify

Plone Support

Hi all,

I have read this: Upgrade Guide

I do this:
> py2/bin/zodbverify -f py2/var/lexikon/filestorage/Data.fs -D

i get this traceback:

AttributeError: Cannot find dynamic object factory for module plone.dexterity.schema.generated: 2

My Question: What is the next Step? How can i find the Object wich produce this Error. I' not so familiar with low-level Zope. Have anyone a hint? This my first Attempt of an Inline Migration to Py3 and i have a lot of Sites for which I have to do that.

Update:

I have patched zodbverify entrypoint.py with my Mountpoint:

def zopectl_entry(self, arg):
    options = parser.parse_args(arg.split(" ") if arg else [])
    # print(options)
    logging.basicConfig(level=logging.INFO)
    make_wsgi_app({}, self.options.configfile)
    app = Zope2.app()
    # my own Mountpoint with a seperat Data.fs
    app = app['lexikon']
    verify_zodb(app._p_jar._db._storage, debug=options.debug)

and run

 py2/bin/instance zodbverify

Surprise!

Ok, i go to the zodbupdate Section. I copy my Data.fs and the Blobstorage to my Py3 Enviromtent.

and run

./py3/bin/zodbupdate --dry-run --convert-py3 --file=./py3/var/lexikon/filestorage/Data.fs --encoding utf8 --encoding-fallback latin1

and surprise, an error occurs:

The above exception was the direct cause of the following exception:

Update

I remove the Data.fs.index, Data.fs.lock, Data.fs.tmp and i run a the script without dry-run option

./py3/bin/zodbupdate --convert-py3 --file=./py3/var/lexikon/filestorage/Data.fs --encoding utf8 --encoding-fallback latin1

Hmm... i'm little helpless.

Update:

I found two Images in a Folder that raises this Error

TypeError("ImplementedBy called for non-factory", cls)

mysterious :roll_eyes:

I delete this two Images, an the zodbupdate runs without Errors.

Ok, i'm now on Plone 5.2 with Python3, but "delete Content-Items" can't be the solution.

AttributeError: Cannot find dynamic object factory for module plone.dexterity.schema.generated

I see this too. This is because no zcml is loaded by the zodbverify script (and probably also not by the zodbupdate script). So this utility from plone.dexterity/configure.zcml is not registered:

<utility
    factory=".schema.SchemaModuleFactory"
    name="plone.dexterity.schema.generated"
    />

This utility implements plone.alterego.interfaces.IDynamicObjectFactory. Apparently this utility is needed when determining the dynamic schema of a dexterity item.

I have fixed this in a patch by registering this utility in Python code. Note that in normal use (bin/instance) this would result in a double registration, but the second one is simply ignored by zope.interface, because it is the same. So it should be safe. Code is:

from plone.dexterity.schema import SchemaModuleFactory
from zope.component.hooks import getSiteManager
sm = getSiteManager()
sm.registerUtility(factory=SchemaModuleFactory, name="plone.dexterity.schema.generated")

Another error that we both saw:

ZODB.FileStorage.FileStorage.FileStorageFormatError

Rather unexpectedly, this is caused by the --dry-run option of the zodbverify script, as you seem to have noticed too.

@mauritsvanrees Shouldn't this be part of zodbverify or another add-on that we can easily drop-in to our buildout?

I have seen that if you add zodbverify to the instance eggs, then you can call bin/instance zodbverify and it will work without this patch, because the zcml is loaded. So for zodbverify it is less needed.

But for zodbupdate it is needed. Maybe it can be aded to plone.dexterity itself. Possibly by registering an empty rename rule and registering the utility in the same module. That way, it is only loaded when zodbupdate is run.

Also, I think zodbverify should load the same rename rules. I don't know if that would be easy to do.

I still wonder why not everyone is running into this...

Rethinking this: no zodbverify should not try to load the zodbupdate renames. You should just run zodbupdate first.
Also, see my new package:
