OK. I realise I explained it in a way that wasn't obvious to understand
- I think I used repository where I meant project in at least one place.
Rather than explain my aims, I can prune the problem down to a similar
example using the test CVS repository:
tools/cvs2svn/test-data/main-cvsrepos
In my terms, each subdirectory of this would be a 'project'. I want to
divide the projects across 2 SVN repositories. eg:
proj -> svn-dev
interleaved -> svn-dev
full-prune -> svn-archive
partial-prune -> svn-archive
Initial commands to do this:
$ cd tools/cvs2svn
$ mkdir tmp
$ cd tmp
$ cvs2svn.py --create -s svn-dev ../test-data/main-cvsrepos/proj
$ cvs2svn.py -s svn-dev ../test-data/main-cvsrepos/proj/interleaved
$ cvs2svn.py --create -s svn-archive \
../test-data/main-cvsrepos/full-prune
$ cvs2svn.py -s svn-archive \
../test-data/main-cvsrepos/proj/partial-prune
The 2nd & 4th cvs2svn commands fail at the start of pass 5:
----- pass 5 -----
loading cvs2svn-dump into svnrepos
<<< Started new txn, based on original revision 1
* adding path : trunk ...svn: Item already exists in filesystem
svn: file already exists: filesystem `svnrepos/db', transaction `k',
path `trunk'
*This* is the problem I was trying (and failing) to relate.
Then...
Because I know that the above commands would jumble the project contents
together inside the SVN repositories, I would have added the "--trunk"
option:
$ cvs2svn.py --create -s svn-dev --trunk trunk/proj \
../test-data/main-cvsrepos/proj
This results in:
Traceback (most recent call last):

However, I realise that doing this might have hit your limitation you
mentioned lower down.
Incidentally - if I *also* add the "--branches" option, the fault
disappears.

Then I understand the limitation at least :-)
I will say that I went down the route of using one cvs2svn command per
CVS project *because* of the documentation - it warns that converting a
repository and the CVSROOT directory 'might not be what you wanted'.
But, once you do have one command per project, you really need the 3
options to keep the projects contents, branches & tags separate from
other projects.
However, there are 2 workarounds that I can think of:
1. Issue each project-oriented cvs2svn command, but between each one,
manually re-arrange the SVN repository so that the next project won't
collide, or cause the loader to die.
2. Re-arrange the cvsroot into N separate directories, moving the
projects around as required (so creating N 'new' CVS repositories). Then
issue one repository-oriented cvs2svn command per 'new' CVS repository.
There are probably more...
Cheers,
Mike
