xdelta3 no_output always fail when run as root #151

Open GoogleCodeExporter opened 9 years ago

The no_output test will always fail as root. Previously, there was code to 
check if uid()==0, but that has been removed in r343.

Previously reported and fixed in issue #67, 
http://code.google.com/p/xdelta/issues/detail?id=67

Tested on linux/amd64.

It's really unsafe to run this sort of test as root, right?

BTW, the reason I removed that statement is that getuid() test isn't portable, 
i.e., the special case was difficult to maintain. That and I think it's unsafe.

If it is unsafe, then maybe something should warn the user not to run 'xdelta 
test' as root?

If there was a portable way to detect whether you are running as root, we 
wouldn't have this problem.
