title: How can I get the SVN file size update info?
body: <p>As far as I know, svn stores a pristine set of files in .svn and when updating, we'll get a difference between svn server and current working copy and update that.</p>
  
  <p>My question is, how can we get the file size to be updated between two revision?</p>
  
  <p>example:</p>
  
  <pre><code>Rev 1: A.txt has "a"
  Rev 2: A.txt has "b"
  Rev 3: A.txt has "bbb"
  </code></pre>
  
  <p>so for 1 and 2, if I do a diff, it'll show something like</p>
  
  <pre><code>A.txt
  
  -a
  +b
  </code></pre>
  
  <p>right? </p>
  
  <p>That's the patch that'll be transferred from svn server to my local working copy if I update file A from R1 to R2, how can I know the size of the patch, in bytes maybe?</p>
  
  <p>I've tried svn diff, svn status -u and svn mergeinfo, does not seems to have what I'm looking for.</p>
