Description Tim Waugh 2005-12-08 12:00:42 UTC

Description of problem:
The dispatcher process is spawned with a stdin file descriptor that is
non-blocking.  It would probably be better if it were blocking.

Version-Release number of selected component (if applicable):
audit-1.1.2-1

How reproducible:
100%

Steps to Reproduce:
1. See bug #173283.
  
Actual results:
Shell script will busy-loop.

Expected results:
No busy-looping, read() call waits until data is available.

This is by design since dispatching events is secondary to logging to disk. The
audit daemon is in a race with the OS to dequeue events before the backlog
overflows. Because of this, the dispatcher comm is done with non-blocking
techniques.
