Fixed:
$ rm -fr tmp-glibc/cache/default-glibc/qemux86/x86_64/bb_cache.dat* ; bitbake -p
Press the first Ctrl-C when the parsing process is at about 50%:
Keyboard Interrupt, closing down...
Then presss the second Ctrl-C:
File "/path/to/bitbake/bitbake/lib/bb/ui/knotty.py", line 619, in main
event = eventHandler.waitEvent(0.25)
File "/path/to/bitbake/lib/bb/server/process.py", line 591, in waitEvent
self.eventQueueNotify.wait(delay)
File "/usr/lib/python3.5/threading.py", line 549, in wait
signaled = self._cond.wait(timeout)
File "/usr/lib/python3.5/threading.py", line 297, in wait
gotit = waiter.acquire(True, timeout)
KeyboardInterrupt
Capture the second KeyboardInterrupt during stateShutdown is running can fix
the problem. There may be still tracebacks for the third KeyboardInterrupt, but
I'm leaning to not fix it since we aimed for supporting 2 KeyboardInterrupts
only.
