1. Patching old code is always The Bad Idea (tm) - you'll get a lot of headaches with forward-porting results into current codebase
2. You must read and understand SVN Book chapters about branching and merging before starting a patch-trip

If you can't commit from outdated WC to repo, you have to have path in repo with the same verson , as you want to modify

In order to get it, you can|have:

• Update your WC to <OLDREV> (done)
• Create new branch in repo from your WC
• Hack-commit-debug code to branch
• When you finished patching, try to merge ( merge ...--dry-run ) trunk to your branch (in order to integrate changes of historic code into current codebase), get "Merge Hell", resolve all conflicts
• Debug resulting code-mix in branch, get it in OK-state
• Merge branch back to trunk
