Description (last modified by john)

Need to write a test cases to be sure. Known issues:

1) NOTE_EXEC clears fflags?
2) NOTE_TRACK does not trigger NOTE_TRACK events.
3) Modifying NOTE_EXIT to NOTE_FORK of a running child triggers a

spurious event.

4) NOTE_TRACKERR is set after KNOTE_ACTIVATE(), possible regression

1) is confirmed if NOTE_EXIT is not being monitored.

comment:5 Changed 13 years ago by john

1) actually ended up being exec() failing, so not a bug.

2) is covered by updates to kqueue(2) in ​r253656

3) ended up being that process exit always generates an EV_EOF event, even it NOTE_EXIT is not being monitored. I've started a thread on arch@ about that behavior.
