upgrading from repo format 1
I was a very early SVN user. I have a repo last timestamped January
2003 that I want to get files and data out of. When I run svn upgrade,
I get:
svnadmin: E165005: Expected repository format '3' or '5'; found format '1'
Do I need to install an intermediate version of SVN in order to
upgrade? If so, which version would you advise that I use?
Thanks,
Ben

Hi Nico
Thanks for your suggestion, which gave me an idea: I can copy the repo
on a USB drive, boot an old live system of some kind, and checkout the
repo onto my USB drive. It's just a matter of which version I need to
support the version 1 repository format.
Cheers, Ben

I have been using SVN since version 1.0. On the server where the repo
lives, SVN is now 1.13 (it has just been upgraded over the years).
It's just that the repo was left behind.

The year is pretty irrelevant. But the version of subversion on your
old server is, and the modern subversion may not support the obsolete
format.
What version of subversion on what operating system was your original
server? And what are you tyring to upgrade to?

See above. There are obsolete versions of subversion on various
obsolete operating systems, which may be possible to virtualize easily
to gain access ot old software rather than recompoiling.

Right, for pre-1.0 format bumps it's pretty much a given that the
repositories are not compatible.

Nope, after echo 3 > format:

What are the differences between f1 and f3? Would «echo 3 > format»
(plus perhaps some manual edits) allow current svnadmin's to dump the
repository?

Repository format 1 is really, really old; older, in fact, than
Subversion 1.0, which used format 3 and did not offer backward
compatibility with pre-1.0 repositories.

The latest version that I can find that used format 1 is 0.27.0:
https://svn.apache.org/repos/asf/subversion/tags/0.27.0
If you can build that version (which is probably going to be quite
challenging, given its dependencies -- IIRC we still used APR-0.9 and
some old, probably now unavailable version of Berkeley DB), you can then
dump the repository with that old version of 'svnadmin'. It's likely
that the current svnadmin can read such old dumps.
(And if not -- surely that's a bug and can be fixed because we do
promise to support repository dump formats indefinitely.)

I ran 'svnadmin upgrade /path/to/repo'.
BTW, repo/format says "1".

I don't know offhand what SVN_REPOS__FORMAT_NUMBER was in 2003 — that's
several years before I joined the project — but first things first, I'd
like to confirm that you aren't running into https://subversion.apache.org/issue3744.
Did you run «svnadmin upgrade /path/to/repo/db» or «svnadmin
upgrade /path/to/repo»? The latter would be correct.
Cheers,
Daniel
