svndumpfilter - unsupported dumpfile version

Question

I', trying to migrate a part of my SVN repository to new location. I dumped the whole repository and now try to filter out my folder of interest:

$ svndumpfilter include sandwiches < dumpfile > filtered-dumpfile

But then I got following error:

svndumpfilter: unsuported dump file version: 3

I came across quite old article saying dump filter is not working if repository dump was created with --deltas flag.

Question: Is there any possibility to use svndumpfilter with dump file with deltas?

Answer 1

No, you can't. svndumpfilter can't operate with deltified dumps.

Check the SVNBook:

The second useful option is --deltas. This option causes svnadmin dump to, instead of emitting full-text representations of file contents and property lists, emit only deltas of those items against their previous versions. This reduces (in some cases, drastically) the size of the dump file that svnadmin dump creates. There are, however, disadvantages to using this option—deltified dump files are more CPU-intensive to create, cannot be operated on by svndumpfilter, and tend not to compress as well as their nondeltified counterparts when using third-party tools such as gzip and bzip2.
