[SVN]How-to recover from checksum mismatch errors in SVN

1.check out the directory in other place, we'll call it the tmp_directory
2.delete the files in the following directory:
working_directory/.svn/text-base
before that , you can make a copy in case any thing bad happen
3.copy the files in tmp_director/.svn/text-base to working_directory
4.everything is back to normal now

the reason for something like that happen is the files in working_director/.svn/text-base/ is different from the one stored in the server.And it perfectly explains the problem.
