title: How do I get SVN to realize a binary file's changed if the filesize is fixed
body: <p>I'm working with a program that writes data to fixed-size binary files that I store in a subversion archive.</p>
  
  <p>The problem, however, is SVN (both the command-line client and TortiseSVN) thinks that since the size of the file didn't change, the file itself didn't change and it shouldn't commit it.</p>
  
  <p>Is there a way to change what diffing method is used, or do I have to resort to hacks such as adding a dummy property to the files?</p>

  <p><strong>EDIT</strong>: Turns out the solution wasn't becuase of the file-size thing.  I just automatically assumed that would be the case, since most nieve diffing altorithims do this all the time.  <sup>[weasel words]</sup></p>
