Faking obliteration
Is there a way to obliterate information from a repository, perhaps
automatically? I'd like to permanently remove a certain file from the
repository. To do so, it would be acceptable to rebuild the directory
from scratch, skipping all information relevant to that file, or to
operate on the repository directly.
Can anybody give hints on how to achieve that?
Regards,
Martin

It's documented here:
$ cat doc/book/TODO
[...]
Here is a list of all the things that the Subversion Book DOESN'T yet cover.
[...]
- svndumpfilter. in particular, show how to "migrate" a subdir in
one repos to a subdir in another one.
[...]
The book guys are workin on it. ;-)

Well.. `svndumpfilter help` is the only docs I'm aware of. You should also
make yourself familiar with the dumpfile format so as to understand what
exactly you're doing. Read notes/fs_dumprestore.txt in the source.
Also read this thread:
http://www.contactor.se/~dast/svn/archive-2003-03/1520.shtml
The svndumpfilter usage is pretty simple - to filter out some file or
directory from repository you only need exact path where it was first committed.
Then you do svnadmin dump repos | svndumpfilter exclude path/to/ >newdump.
Then you load newdump into a separate repo and triple-check that it's ok.
This can get pretty complicated if you moved the file around the repo, then
later created other file with the same path in repo, etc, etc.
Svndumpfilter will catch copies of the file, but i think it will also catch
unrelated file with the same name in a later revision.
In this case you'll have to separately svnadmin dump and filter several
revision ranges.

That sounds very promising, thanks!
Is it true that svndumpfilter is nowhere documented?

See issue 516.
For now, all you can do is dump and load. Use svndumpfilter to
'screen out' the bad path when you're reloading.

It's called 'svn obliterate' ... and it exists only in our dreams (and
future plans). You can accomplish the task through crafty use of
'svnadmin dump' and 'svnadmin load', though.

Try:
svnadmin create /path/to/new/repo
svnadmin dump /path/to/repo | svndumpfilter path/to/obliterate | \
svnadmin load /path/to/new/repo
That *should* work. I think :)

It may look like I'm just sitting here doing nothing,
but I'm really actively waiting for all my problems to go away.
If you're not having fun, you're not doing it right!
