SVN: Prevent a newer client from upgrading a working copy's SVN version?

Is it possible to prevent a newer SVN client (say 1.6) from automatically upgrading a working copy that was checked out with an older client (say 1.4 or 1.5)?

I find that as soon as I touch a working copy with a newer clien开发者_C百科t, anyone using an older client to work with the same files can no longer do so (for obvious reasons).

Assuming requiring everyone to upgrade their SVN clients isn't an option, is there a configuration setting or flag I can set to prevent my newer client from making this change?

Andy's answer is misleading — there is nothing wrong with using multiple client versions on the same repository; the problem you're describing arises when multiple client versions are being used on the same working copy.

So unless the same person is using multiple clients (which could certainly happen, e.g. command line client + TortoiseSVN), it shouldn't be a problem to not have every person upgrade their clients.

To directly answer your question, no it is not possible to prevent auto-upgrading of working copies, but it is possible to undo it after the fact. See the release notes for a Python script that will accomplish this.

It seems counter-intuitive to me that you have multiple people using the same working copy. Having multiple clients is one thing (for example, I have AnkhSVN and TortoiseSVN that access my working copies) but having multiple people using the same working copy is - to me - not the normal way SVN should be used.

I would say the "ideal" solution would be to give each person their own working copy, and then let them use whatever client version they like.

Working on a repo with multiple client versions is not recommended for this reason! You can set access permissions per user and use different clients on your local machines with different SVN users.
