Subject Re: How to recover from a "checksum mismatch"
Date Sun, 21 Feb 2010 12:26:16 GMT
I am afraid you misunderstood my problem, or maybe I misunderstand you solution.
Let's say
  .svn/text-base/README.svn-base
got corrupted.  For this discussion it is irrelevant "how" it got to
be corrupted.  The problem is that now the working copy is in an
unusable state and  svn revert should restore it to a working state.

Here are the commands I use (assuming README is underthe version control):

1. chmod u+w .svn/text-base/README.svn-base

Now make some changes:
2. pico .svn/text-base/README.svn-base

Now make some other changes to the proper file:
3. pico README

4. svn up
At revision 185.

5. svn commit -m "ttt"
Sending        README
Transmitting file data .svn: Commit failed (details follow):
svn: Checksum mismatch for
'/Users/gregoryberkolaiko/projects/berkment/.svn/text-base/README.svn-base';
expected: '5a6a937b0f8952d6a9c9da4a396e0aa1', actual:
'c92c10f82a4f704133c67def8fde242a'

Now what?

Suppose I am to give up on my changes:

6. rm README

7. svn up
Restored 'README'
At revision 185.

If you inspect README, you notice that it got restored not to the
repository state, but to the local cached state
(in essence, "cp .svn/text-base/README.svn-base README")

svn revert
does exactly the same: uses the corrupted local cached version.

There should be a way to revert the cached version too!

Best wishes,
Gregory
