[ptt-users] setFile corrupting data on multi-part HTTP POST?

[Mark.Lutton at thomson.com]

I can verify the fix easily.  I have a script that requests a jar file from the server.  There's a bad byte in the first line of the hex dump of the file; also I can compare it to the correct file.
 
I don't know all the details of encoding and decoding in Java and Python.  Java's OutputStreamWriter and InputStreamReader have parameters that specify the character set (like "UTF-8").  Maybe Python has those too.  I guess you call URLConnection.getContentType(), get the encoding out of that and pass it to the InputStreamReader constructor.

Thanks for posting the workaround Mark but this really should be 
fixed. I'm going to see what I can do in the short term.

When I have a fix are you available verify the fix works?

Thanks.
