Subject: procps: ps doesn't resolve uid->username of some processes

Date: Wed, 21 Feb 2007 13:53:35 +0300

Package: procps
Version: 1:3.2.7-3
Severity: normal

Processes which are running under users haldaemon and messagebus are displayed
somehow different by ps utility. The following output of ps shows that their
uids are not resolved into usernames. They are left 102 and 103 correspondingly.
A simple test program that uses getpwuid() libc function works correctly, so
this is not a bug of libc6 but the bug of procps package.

This is a common "not a bug", see also #405063.

[Message part 1 (text/plain, inline)]

As mentionned by Justin, this is not a bug.
I don't really find any documentation about this but the source code of
recent version of procps seems to be quite sufficient (unless i'm
wrong).

In minimal.c:

[...]
static void print_proc(void){
[...]
  case 'f':
    printf(
      "%8s %5d %5d %s %s %s %s",
      do_user(), P_pid, P_ppid, do_cpu(0), do_stime(), P_tty_text,
do_time(P_utime+P_stime) );
[...]
