Can I delete a commit in Subversion?

Question

Per accident I committed twice because I forgot to add two files. Can I remove a specific commit from the log?

1. AFAICS, you have not delete r4, but merge with r5, yes?
2. In general, SVN commit history is immutable, as Sii said - and if you haven't rights delete/create repo - you can't do anything.

If you can delete current repo and create new with new history, you can try:

• svnadmin dump for getting human-readable (barely, I have to say) repository-dump, grok format and edit dump, delete repo, svnadmin load to recreate the repo
• another idea is (instead of editing dump) another SCM, which has a bridge to SVN (hg+MQ (histedit)+hg-git, f.e, will allow you to get repo and fold/delete changesets). For replacing old repository - see p.2 above
