Double Ctrl+C doesn't seem to kill all bitbake's sub-processes: steps to reproduce: 1. Create a simple class with a simple task, e.g: python do_testimage() { import subprocess, time subprocess.Popen("ping 127.0.0.1", shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT) # do something for a while endtime = time.time() + 1000 while time.time() < endtime: pass } addtask testimage 2. bitbake something -c testimage: NOTE: Executing RunQueue Tasks Currently 1 running tasks (164 of 164): 0: core-image-sato-1.0-r0 do_testimage (pid 9762) Meanwhile check ps output stefans 9671 4676 5 12:02 pts/0 00:00:03 python /home/stefans/z/poky/bitb stefans 9720 9671 29 12:02 pts/0 00:00:15 python /home/stefans/z/poky/bitb stefans 9742 9720 1 12:02 pts/0 00:00:00 python /home/stefans/z/poky/bitb stefans 9762 9742 98 12:02 pts/0 00:00:39 python /home/stefans/z/poky/bitb stefans 9765 9762 0 12:02 pts/0 00:00:00 ping 127.0.0.1 3. Double Ctrl+C bitbake - build stops However running bitbake <something> again ERROR: Only one copy of bitbake should be run against a build directory Check ps output again. I still have: stefans 9762 1 99 12:02 pts/0 00:01:11 python /home/stefans/z/poky/bitb stefans 9765 9762 0 12:02 pts/0 00:00:00 ping 127.0.0.1 I have to kill the ping process then the python process ends.
I'm sorry for the ps truncated output, (narrow terminal and didn't used -w option on ps -ef) in step 2: Currently 1 running tasks (164 of 164): 0: core-image-sato-1.0-r0 do_testimage (pid 10211) stefans 9992 9989 0 12:05 pts/0 00:00:00 ping 127.0.0.1 stefans 10120 4676 7 12:07 pts/0 00:00:03 python /home/stefans/z/poky/bitbake/bin/bitbake core-image-sato -c testimage stefans 10169 10120 37 12:07 pts/0 00:00:15 python /home/stefans/z/poky/bitbake/bin/bitbake core-image-sato -c testimage stefans 10191 10169 2 12:07 pts/0 00:00:00 python /home/stefans/z/poky/bitbake/bin/bitbake-worker decafbad stefans 10211 10191 99 12:07 pts/0 00:00:27 python /home/stefans/z/poky/bitbake/bin/bitbake-worker decafbad in step 3: stefans 10211 1 99 12:07 pts/0 00:01:31 python /home/stefans/z/poky/bitbake/bin/bitbake-worker decafbad stefans 10214 10211 0 12:07 pts/0 00:00:00 ping 127.0.0.1

As another data point, we discovered a bug when we dropped pre python 2.7.3 support in that our multiprocessing pool workaround was always being used. There is a slim chance that now we require 2.7.3, the issue might be resolved...

Hi Cristiana and Ross In the bug triage meeting, we decide to reassign this bug to Cristiana but very likely need Ross's help. So please work together.
Patch sent on bitbake-devel.
