copied!<p>Since there's really no way to <em>programmatically</em> track the progress of rsync, I think your best bet is to "screen scrape" its output and try to "guess" at its progress somehow.</p> <p>The first thing you should do is use <code>subprocess</code> instead of <code>commands.getstatusoutput</code> because you'll get much more control over screen scraping rsync's stdout to track its progress. One solution might be to execute rsync with the <code>-v</code> option, which will print each file transferred followed by a newline (plus some other cruft that you don't really need). A simple way to guess at the progress of rsync then, would be to do something like:</p> <pre><code>import subprocess p = subprocess.Popen(['rsync', '-v', ..other rsync args..], shell=True, stdout=subprocess.PIPE, close_fds=True) while p.stdout.readline(): ... # rsync has just "completed" an operation, i.e. it probably # transferred a file. now would be a good time to update the # ProgressBar. there are some options here, see below... ... ret = p.wait() print "Rsync exited with code %d" % ret </code></pre> <p>This reads the output of <code>rsync -v ...</code> one line at a time, and in the <code>while</code> loop you would update the <code>ProgressBar</code> as appropriate. The question then becomes, what kind of update? <code>ProgressBar</code> really has two modes - one that "pings" back and forth indicating progress towards some indeterminate goal, and one that moves the bar from left to right based on an increment towards a known goal.</p> <p>You could try to "guess" the number of files rsync will transfer by obtaining a file list before hand (with <code>--list-only</code> or <code>-vn</code>) and use that as the goal, but this is inherently error-prone because you run the risk of the sender's file list changing in between the time you gather the list and when you actually execute rsync. A better solution is probably just to call <code>pulse()</code> on the <code>ProgressBar</code> in the <code>while</code> loop to indicate that things are happening in the background. If you want to display more information, you could read the output of <code>p.stdout.readline()</code> and update a <code>gtk.Label</code> somewhere to indicate which files are being transferred.</p> <p>(Note: the code above doesn't take into account error conditions when executing rsync, which you should probably do)</p>
