Cannot Restore Previous Revision of File Deleted from Repository

[Cory Myers <co...@corymyers.com>]

Hi,

I have one project---`/var/repo/proj/dejgen/`---which I accidentally  
deleted from both the repository (`svn rm /var/repo/proj/dejgen/`)  
*and* the working copy (`rm -rf ./dejgen/`) simultaneously. The `svn  
rm` commit was revision 13 in this particular Subversion repository;  
the original files for this project were imported at around revision  
10. When I try to run `svn co /var/repo/proj/dejgen/@12 .` to get  
revision 12, the one just prior to my accidental `svn rm`, I receive  
the following error message:

 > svn: File not found: revision 13, path '/dejgen'

My understanding of Subversion is that even `svn rm` should allow the  
project to be checked out from an earlier revision, and I'm eager to  
recover what I accidentally deleted. Any suggestions or  
clarifications ye could offer would be greatly appreciated.

Thanks,

Cory Myers

Due to the strangeness of peg revisions, you need both -r 12 and
http://url/blah@12 on that checkout.

What you probably want though is to just copy from the previous
revision, something like what's described here:

http://svnbook.red-bean.com/nightly/en/svn.branchmerge.commonuses.html#svn.branchmerge.commonuses.resurrect

I believe you want:

svn co -r 12 file:///var/repo/proj/dejgen@12

That will check out the pre-deletion version of the project, but of  
course you cannot commit any changes to it because it's not HEAD, and  
you can't update to HEAD because it would delete itself.

If you want to restore the project, then this may be what you want:

svn cp -r 12 file:///var/repo/proj/dejgen@12 file:///var/repo/proj/ 
dejgen -m "Restoring deleted project"
