KeyError: 'getpwuid(): uid not found: 999'

Hello,

Hello,

I'm trying to get psdash running (it uses psutil), but when checking processes psutils produces the error mentionned in the title, please see the full error log: Jahaja/psdash#36

I tested with psutil 2.1.1 and 2.1.3 as psdash requirement in their setup.py

I checked (with ps -le | grep 999), uid 999 is related to postgres/murmurd/mongodb on my system, and doesn't seem to have an associated user:

cat /etc/passwd | cut -d':' -f1 | xargs -I {} id {}

shows no user with uid 999

Apparently, psutil can't handle such case. Any ideas?

Sorry, this totally slipped under my radar. KeyError: 'getpwuid(): uid not found: 999' originates from the pwd module which is not able to resolve UID 999. I'm not sure what's best to do here. We could catch the exception and return 999 but letting the exception propagate also looks kinda correct to me. Not sure...

The issue was fixed in Jahaja/psdash#36, I think this can be closed.

After some thought I think this should be handled by psutil, mainly because if we use Process.as_dict() instead of Process.username() directly the whole operation will fail. Fixed in 4dfb4ad.
