389336 - jprof tinderbox broken

Status: RESOLVED FIXED

(Core :: General, defect, P2)

Description

I went to look at rhelmer's tinderbox that uploads jprof data, but all the output files contained was:
mmap: Success 

It's possible jprof is broken, or something in the way the tinderbox is using it.

Looks like it's burning right now:

I'll see if the nightlies have been working or not; it should not be pushing data unless it has a green build and the tests don't crash.

I see this in the logs; checking it out further.

JPROF_RTC setup: open("/dev/rtc", O_RDONLY): Device or resource busy
  jprof: Error initializing RTC, NOT profiling
  
  (Gecko:7300): GnomeUI-WARNING **: While connecting to session manager:
  Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed.
  Could not start jprof-profiling since JPROF_FLAGS was not set.

Oh :/ There were a ton of hung builds and crash reporter processes, so /dev/rtc was in use. 

Ted how can I turn off and/or auto-submit crashes in breakpad? :)

MOZ_CRASHREPORTER_DISABLE=1 if you don't need to run the unit test, MOZ_CRASHREPORTER_NO_REPORT=1 if you do.  It's all right here in this handy pamphlet:

I'll see if I can ressurect this machine.

Comment 6

[Chris Cooper [:coop] (he/him)]

I've set MOZ_CRASHREPORTER_NO_REPORT=1 in cltbld's ENV (via .bash_profile) and clobbered the build.

[Chris Cooper [:coop] (he/him)]

I honestly have no idea how the X server was setup previously such that cltbld might actually be able to attach to it. It was running as root in runlevel 5 with respawn on, and I certainly couldn't get tinderbox to attach to it using the standard bag of tricks. 

I've now switched it to runlevel 3 and have it running metacity as cltbld. This needs to be started by hand on reboot, but there is an .xinitrc file present so startx should just work.

This is the same setup as on bl-bldlnx03 so at least two linux machines on this network will be using the same linux X strategy now.

I noticed this still isn't working; Couple more things here:

1) /dev/rtc read-only
* set rtc to 666 in /etc/udev/permissions.d/50-udev.permissions

2) gnome-segv was using /dev/rtc (probably due to gnome catching the crash since breakpad is turned off)

I fixed this in the middle of a run, but I see some data now so I am hopeful that it'll actually work the next run. We need a way to keep an eye on this.

We've got data now, looks good again:
