darwin "ps" display parsing in OS-X Tiger causes all procs to vanish in display
Hi guys. OK, enough asking a million questions (thank you all!), now it's time for bug reporting.
Systems: Apple X-Servers. I have two. The one running OS-X 10.3 is fine. The one running OS-X Tiger 10.4 is being weird. And I figured it out.
The symptom on the newer OS is that under the "procs" column, all I see is the process header line, followed by only a small part of the first process listed- and NOTHING else. It looks like this on the web page:
PID PPID USER STARTED STAT PRI %CPU TIME %MEM RSS VSZ COMMAND 1 0 root 13Jul06 S
After digging, I figured out what's happening.
OS-X 10.3: (normal)

It's the first line that's causing the hobbit procs parsing to break. Specifically, the "S<s" status. While I don't know enough OS-X tobe dangerous, I suspect it's a new type of process status under the latest Darwin. The "<" in the status is normal, and this is causing the procs parsing in hobbit to cut off everything beyond that.
1 0 root 13Jul06 S<s 32 0.0 0:17.23 -0.0 500

This of course makes any procs check useless (in my case,I was checking for simple things, like "cron", etc - and the test fails of course, since there's no such (or any other!) process listed..................

I can see why it would stop it from appearing on the web page (since your browser then interprets everything after the '<' as an unknown
- very large - HTML tag. But the client parsing code works regardless of this, and should handle the process listing just fine.
Could you verify if the following URL http://www.hswn.dk/hobbit-cgi/bb-hostsvc.sh?CLIENT=voodoo.hswn.dk§ion=ps (adapted to match you Hobbit server hostname and the OSX client name, of course) returns the full "ps" listing, or only a part of it?
