Bug 497438 – sys-process/procps-3.3.8-r1: top missing processes when user filter applied

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description mikef 2014-01-07 19:45:55 UTC]

After a recent upgrade from procps 3.3.6 to 3.3.8-r1 I noticed that tasks were sometimes missing from top when it was filtered by user. This looks to have been fixed upstream (see https://gitorious.org/procps/procps/commit/e6a78f2745ca6c7ceed4406d3ce5397e77518b11) and applying that commit between ebuild unpack and ebuild compile does appear to fix the problem for me.

Reproducibility:
Happens sometimes, but not always.

Steps to reproduce:
1. Start top.
2. Filter by a user (type the letter u, followed by a valid user name, followed by Enter).
3. Change the sort order (e.g. by alternately pressing capital T and capital P).

Actual results:
Processes appear and disappear, seemingly dependant on the sort order, even when they are running throughout.

Expected results:
top shows all processes owned by the user.
