Hi,
I don't have an explanation for this. I'm working with libvirt
0.9.1 which pulls in gnulib. When I build on a bare machine or
a minimal lxc container, test-poll passes. When I build in an
schroot, it fails because when it does a poll after the other
end has shut down, it does not get the expected POLLHUP|POLLER.
Instrumented debug output looks like:
Unconnected socket test... Connected sockets test... Unconnected socket
test... passed
General socket test with fork... Connected sockets test... passed
poll1_wait returned 0x5, POLLHUP|POLLER is 0x18
# define POLLIN 0x0001 /* any readable data available */
# define POLLOUT 0x0004 /* file descriptor is writeable */
failed (expecting POLLHUP after shutdown)
failed General socket test with fork
General socket test with fork... failed (expecting POLLHUP after shutdown)
failed General socket test with fork
Pipe test... Pipe test... passed
strace output for both is attached. The child exits before the poll in
either case.
Any ideas?
thanks,
