used when a read filter is requested on a write-only fifo descriptor, or a write filter is requested on a read-only fifo descriptor. This permits the filters to be registered, but never raises the event, which causes kqueue behavior for fifos to more closely match similar semantics for poll and select, which permit testing for the condition even though the condition will never be raised, and is consistent with POSIX's notion that a fifo has identical semantics to a one-way IPC channel created using pipe() on most operating systems. The fifo regression test suite can now run to completion on HEAD without errors. MFC after: 3 days |
