fs_copy FROM a transaction root?

From: Jean-François Doyon <jfdoyon_at_methane.ca>

I'm developping a Zope (http://www.zope.org) object storage system based on
Subversion's filesystem functionality, on top of Ape
(http://hathaway.freezope.org/Software/Ape). I'm using the Swig/Python API.

I've run into a problem with trying to do move/renames.

The application starts a transaction, executes a variety of filesystem based
operations, and then commits.

One of those operations might be a move/rename.

But, when Ape does this, it does so twice, using a temporary file.

So if I have a file "A" I want to rename to "B" this happens:

A -> TMP
TMP -> B

This is causing me problems because the svn_fs_copy (fs.copy in Python)
wants a REVISION root as a source ... My TMP file gets created within a
transaction however, so I can't really do the TMP -> B step ...

The use of the temporary file gets done by the application (Actually Ape,
the storage adapter) itself, so I don't really have any control over that

Anybody have any idea how I might get around this ? Seems to me I shouldn't
be the first (or last) to have this issue, but didn't see anything in the

Any insight would be greatly appreciated !
