Using select() to check whether a pipe is ready for writing seems to fail on Mac OS X 10.8 and 10.9. See the PR for a small C program to demonstrate. It's possible that the small program is broken and there's no bug, but the program works on Linux and on Mac OS X 10.7 and 10.6. Although poll() seems to work, switching completely to poll() is not a good option on Mac OS X, since poll() does not support devices on that platform. The kqueue() facility seems to handle pipes and writing ok, so work around the bug by enabling the use of kqueue() on pipes. Closes PR 14596 |
