Undoing last commit

[Kenneth Porter <sh...@sewingwitch.com>]

Not quite grasping how the vendor drop thing was supposed to work, I 
committed a new copy of a vendor drop instead of a delta from the previous 
version, bloating my repository by the size of the entire drop. I'd now 
like to remove that, but I think if I just delete that tag, it leaves the 
storage consumed. Correct? If so, is there some way to undo the commit and 
release the storage? (I haven't committed anything since my error.)

You can't obliterate the unwanted revision from the existing repository.

I would dump all revisions up to the culprit, and then load them into a
new repository.  Look up 'svnadmin dump' and 'svnadmin load' in the
book.  You could even follow it's saucy suggestion for avoiding
temporary storage.

If I'm correct, one of the principles of Subversion is that no data ever
gets destroyed.  So, to make that commit go away, you would probably have to
do something along the lines of:

1. Dump your current repository to a dumpfile.
2. Backup your current repository in case something goes wrong.
3. Edit the dumpfile, removing the last revision.
4. Re-create the repository using 'svnadmin create'.
5. Load the edited dumpfile.

Someone more knowledgable than myself may have a better solution.
