SVN blues – committing a file that doesn’t appear to have changed

So recently I had an issue where I needed to commit a Truecrypt file in SVN, but as you probably already know, when you save content in Truecrypt, the file appears to be untouched to SVN. The modified date doesn’t change, nor does the size of the file. So, how to we check-in our changes?

A co-worker generously gave me this tip, so I’m passing it on to you:

from the CLI

#svn propset dummyproperty 1
#svn commit

By changing the properties of the file with useless info we can fool SVN into letting us check-in our file!
