Bug Description

FTP Upload of files into a BTreeFolder2 in the ZODB returns this error:
Server response: '426 Error creating file.'

More details would be nice, like a server side traceback. But given how FTP is basically unsupported, this wouldn't surprise me.

How do I get the traceback? The event_log and the error_log in the zmi do not show anything, even though I'm in debug-mode.

I tried again, running Zope in fg-Mode, but there is no error showing up in the console.

This bug also occurs when you try to put an item thru webdav.

When a PUT request is done (by webdav for instance), the ressource url requested looks like this:

During traversersing, the object targeted by 'path/to/btreefolder' is correctly retrieved.

Then, the 'my_new_file.txt' is searched, and does not exists, so, a NullResource shoud be created to handle the request.

With a regular folder, it behaves like that.

With the BTreeFolder2, the __getitem__ method, that is used in this case, is inerited from BTreeFolder2.BTreeFolder2Base and does not implement this behavior.

It can be fixed with the patch file joined to be applied at Products/BTreeFolder2/

I've forgotten to mention that the patch also solve the bug for the initial problem reported.
