title: Check if large local file differs from a large file in svn repository
body: <p>I would like to check if a large local file <code>large_file</code> (about 300MB) differs from a file in a remote subversion repository <code>svn://server/repo/large_file</code>. The local file is not part of a checkout if the repository.</p>
  
  <p>I can get the sha checksum of the local file with</p>
  
  <pre><code>&gt; svn info large_file | grep Checksum
  Checksum: a9d0a9859f0b251d5ea03c6d5cf1d5a65b072127
  </code></pre>
  
  <p>Getting the checksum for the file in the repository, does not work:</p>
  
  <pre><code>svn info svn://server/repo/large_file | grep Checksum
  </code></pre>
  
  <p>This is strange because according to a <a href="http://svn.haxx.se/users/archive-2008-08/0332.shtml" rel="nofollow">discussion on the svn users mailing list</a> the checksum is stored in the server.</p>
  
  <p><strong>Rationale:</strong> In the context of machine learning, I'm working on a script that checks that the dependencies of a model are actually coming from the mentioned svn repository.</p>
