Under a high load and while resizing the terminal window, I received the following traceback:
Traceback (most recent call last):
File "/bitbake/bin//bitbake", line 263, in <module>
ret = main()
File "/bitbake/bin//bitbake", line 252, in main
return server.launchUI(ui_main, server_connection.connection, server_connection.events)
File "/bitbake/lib/bb/server/process.py", line 269, in launchUI
return bb.cooker.server_main(self.cooker, uifunc, *args)
File "/bitbake/lib/bb/cooker.py", line 1407, in server_main
ret = func(*args)
File "/bitbake/lib/bb/ui/knotty.py", line 385, in main
if stdin_mgr.poll():
error: (4, 'Interrupted system call')
Interrupted system calls from a sigwinch are certainly possible and the
right thing to do is just restart the system call, or in this case,
punt and wait until the next poll cycle.
(LOCAL REV: NOT UPSTREAM)
