svndumpfilter --drop-empty-revs errors

Hello, I'm new to the list. I am a release engineer at a media company
in Massachusetts. We're moving to Subversion, from both CVS and older,
ill-configured Subversion setups.


We're running SVN 1.2.3 on RHEL 3.2.3 with Apache 2.0.46.


I am trying to split one large repository, with a number of projects in
it, into smaller repositories. I dumped the entire large repository
(/repos/pd) to pd.dump, filtered it to only include the top level
directory "PDS", dropping and renumbering revisions, and outputting to
pds.dump. When I load the pds.dump into a new repository, I get an
error "No such revision: 812".


I've googled and looked through the archives of the SVN Dev and SVN
Users lists. The only reference I've found deals with a bug associated
with Node-copyfrom-rev nodes. Yes, most of my errors do have
Node-copyfrom-rev fields. However, the first error is a text version
change, not copyfrom.


The commands were:

$ svnadmin dump /repos/pd > pd.dump

$ svndumpfilter include PDS --drop-empty-revs --renumber-revs < pd.dump
> pds.dump

# no errors

$ svnadmin load /repos/pds.temp < pds.dump

# non Node-copyfrom-rev error on rev 812 and possibly others

# Node-copyfrom-rev errors on revs 882, 892, 1346, 2579, 3212, 3326,


The node info for revision 812 is below. I've excluded the data.

Revision-number: 812

Node-path: PDS/IO_Manager/trunk/perl/lib/perl/PDS/Log.pm

Text-content-md5: ea7e14859f33a47c18d6e4ef0628da99

Node-action: change

Node-kind: file

Text-content-length: 1947

Content-length: 1947


There are only two other references in the entire original repository to
this file, both are within the tree. The size of filtered dumpfile is
3994 versions.


When I run svndumpfilter without "--drop-empty-revs --renumber-revs",
the load succeeds. But, of course, I want to move the tree without the
empty revisions.


Has anyone come across this issue before? Does anyone have any ideas
about a resolution? Thank you for any comments or help.
