Cutting/Pasting across databases

[georgpfolz]

It's not a bug, it's a feature request about something that's scaring me in my daily work:

I usually have several databases (ZODBs) mounted in my Zope instances. Copying/Pasting across these databases in the ZMI is not a problem, but Cutting/Pasting breaks the whole instance.

I'm aware of this of course and I'm paying close attention, but nonetheless I would prefer not to have to worry about breaking my instance by mistake.

So here's my request:

Would it be possible to treat cut/paste across databases differently? For example like one of the following:

• aborting the operation with an error
• showing a warning dialog
• performing a copy/paste instead

What version of Python and Zope/Addons I am using:

• FreeBSD 12.3
• Python 3.8.9
• Zope 5.3

You can register a subscriber for `IObjectMovedEvent` and check there that `_p_jar` for the new parent is identical to that of the moved object (maybe, if they are different from `None`).
