OSProcess not showing process name

[dazhitchman]

The OSProcess fails to get the name of the running process if the running user doesn't have permission to the /proc/{pid}/cmdline
e.g. this process ( as reported by ps -ef )
root 6 2 0 Oct14 ? 00:00:00 [kworker/0:0H-kblockd]
returns en empty string for the name of the process
(LinusOSProcess.java:337) --> this.name = status.getOrDefault("Name", "");

The name is available in the /proc/{pid}/stat file which is already parsed into the statArray.
e.g.
6 (kworker/0:0H-kblockd) I 2 0 0 0 -1 69238880 0 0 0 0 0 0 0 0 0 -20 1 0 20 0 0 18446744073709551615 0 0 0 0 0 0 0 2147483647 0 0 0 0 17 0 0 0 0 0 0 0 0 0 0 0 0 0 0

It would be trivial to extract the process name from the stat file when the cmdline access returns null

The name and command line are two different things. /proc/[pid]/cmdline is the full command line including path and arguments. The name comes from /proc/[pid]/status. Does that file have permission issues?

I'm fine with using /proc/[pid]/stat as a backup.

FYI the stat array is numeric and ignores the name, but we do have the string stat. The same backup should be used for the process State, which also pulls from /proc/[pid]/status but could be parsed from stat as a backup.

I'd like to work on this, I won't be able to start before sunday, but im confident to finish it on sunday aswell.

[dbwiddis]

Sounds good. I would like to cut a release on Sunday for the Windows processor bugfixes, but I'll hold off for this one as well!

Fixed in #1368

Good work. Thanks
