| | There are lots of special tricks to such a script. Otherwise, I would
| have written it already. :)
Obviously.
/me slaps his forehead
| OK, here's how I think it needs to happen, with some, hopefuly helpful | notes.
| | 1. The script needs to be run under Zope 2.6 or 2.7. There should
| be a product that people can install that installs some method to
| be run. People should be able to run this method in a running zope.
| They should not need to shut down their site to do the conversion.
| | 2. The method should walk the object tree, converting:
| | - old-style BTrees to modern BTrees
| - old-style buckets to modern buckets
| - intSets to IITreeSets.
Just to check:
+----------+-----------+ | Old | New | +----------+-----------+ | BTree | OOBTree | +----------+-----------+ | IIBTree | IIBtree | +----------+-----------+ | OIBTree | OIBTree | +----------+-----------+ | IOBTree | IOBTree | +----------+-----------+ | intSet | IITreeSet | +----------+-----------+ | bucket? | bucket? | +----------+-----------+
No, this isn't quite right. I don't remember the details off hand.
Think of it in terms of modules:
objects from BTree -> objects from BTrees.OOBTree objects from IOBTree -> objects from BTrees.IOBTree objects from OIBTree -> objects from BTrees.OIBTree objects from IIBTree -> objects from BTrees.IIBTree objects from intSet -> objects from BTrees.IIBTree
| The individual conversions should be pretty simple. At worst involving
| a for loop, but, in many cases, the constructors for the new types will
| be able to accept the old types.
| | 3. The hard part is walking the object tree. You will need a function that,
| given an object, will return the oids of the objects it references.
| Perhaps Jeremy can help you with that.
I hope so *wink*.
Me too. He's pretty busy. If he can't, I'll try to help.
