Hi Achim,
Running builds and bumping them in priority looks okay on current
procps-ng procps under current Cygwin 64, sanitized as in attached which
was limited to COLUMNS=120, also spaces squished and output truncated
for examples below:
F S UID PID PPID C PRI NI ADDR SZ WCHAN STIME TTY TIME CMD
0 S $USER 11102 11101 0 80 0 - 137 - Sep19 pty0 00:00:33 -bash
0 S $USER 5891 11102 0 80 0 - 123 - 08:23 pty0 00:00:00 /_
...
0 S $USER 13448 12388 0 72 -8 - 92 - 08:37 pty0 00:00:24 |
0 S $USER 53596 13448 5 72 -8 - 91 - 10:14 pty0 00:00:00 |
...
but current procps-ng procps under current Cygwin 32 with the equivalent
process priority bumps gives apparently incorrect %Cpu, PRIority, NIce,
and STIME values:
F S UID PID PPID C PRI NI ADDR SZ WCHAN STIME TTY TIME CMD
0 S $USER 1975 1974 0 2278 0 - 103 - Sep14 pty0 00:00:01 -bash
0 S $USER 5266 1975 0 778 0 - 105 - Sep14 pty0 00:00:00 /_
...
0 S $USER 12724 11665 0 23622 0 - 81 - Sep14 pty0 00:00:03 |
0 S $USER 40148 12724 0 60 0 - 75 - Sep14 pty0 00:00:00 |
...
as the sessions are running identical workloads, and the latter was
started at earliest yesterday, the builds today.
I have never managed to catch %Cpu != 0 even though I see that
frequently during builds under Cygwin 64.
Also procps -l without -f does not right align PID and PPID columns
correctly on either arch, or I would have used that instead.
Could you please have a look at this if you get some free time.
