>min(100, int(100 * bytes_read / self.size))
size == 0 -> oops :P

Comment 3 Gene Czarcinski 2014-11-03 13:18:13 UTC
I am working on a fix.

A quick hack is to check for size == 0 and not do the divide by zero (fake it).

Right now, the code copies the specified file to a workarea even if file:/// is specified.  What I want to do is skip all this copy stuff if file:/// specified and just use the file directly.  The solution is a bit more complicated because that file could be a tarball, is squishfs.img or a Live install iso file.

I am dancing as fast as I can.  If someone more expert in python gets there first, I will be happy.  Just, please, cover all the bases for file:/// and the different types of files.

patch to handle liveimg --url=file:// as special case

This fixes the divide by zero by avoiding the whole issue of "downloading" the file.  Instead it uses the file directly.  This has the added benefit of taking a lot less time.

The patch and a updates.img for anaconda-21.48.13-1 are available at http://czarc.org
