Review request for kde-workspace and David Stephen Hubner.
Bugs: 327382
http://bugs.kde.org/show_bug.cgi?id=327382
Repository: kde-workspace
Description
-------
ReadPipe() doesn't return 0 as expected in the case that the command is not
found. but the length of sh's output which is "command not found" in this case.
This is because popen() does not fail if the command is not found, because it
_can_ run "sh". (according to the man page, popen calls "/bin/sh -c command")
To fix this, ReadPipe() should check the return code of the call to pclose()
(see "man pclose"), and return 0 if this is not equal to 0.

Testing
-------
Run KInfocenter on openSUSE, where lspci is in /sbin and that is not in the
user's path.
Without this patch, 3D Accelerator will be shown as "unknown" (because lspci
cannot be run, with this patch it works as intended.
I also tried with lspci in /usr/bin/ (i.e. in the path) and completely removed,
worked as expected (correct information in the former case, "unknown" in the
latter).
Thanks,
Wolfgang Bauer
