Title:
select's FD_ISSET returns true with no data to read
Status in linux package in Ubuntu:
Incomplete
Bug description:
Description: Ubuntu 14.04.3 LTS
Release: 14.04
Ubuntu 3.13.0-65.105-generic 3.13.11-ckt26
3.13.0-63-generic seems to work fine, but in 3.13.0-65-generic, when
using select; FD_ISSET returns true even when there is no data on a
tty with min=0, time=0. getchar() returns -1
Wondering if it's anything to do with the fix for
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1397976 which was
added in 3.13.0-65.105?
Actually noticed this within sox:
play xx.wav
hangs due to continually reading the tty (it's not great code - but it
showed up the bug). Whereas:
play xx.wav < /dev/null
is fine.
Cheers,
Tarim
