           Summary: GstPoll fails on MacOSX
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Mac OS
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)

Running suite(s): GstPoll
66%: Checks: 6, Failures: 2, Errors: 0
gst/gstpoll.c:207:F:general:test_poll_wait_restart:0: Write descriptor should
be writeable
gst/gstpoll.c:311:F:general:test_poll_controllable:0: Write descriptor should
be writeable


The problem seems to be well known ([0], [1]) and comes down to
stdin/stdout/stderr being devices and not pipes on macosx ... and therefore not
pollable (they return POLLNVAL straight away).

The second link proposes a fix... but something tells me it's maybe not what we
want.

Shall we limit usage of GstPoll on macosx to fds different from
stdin/stdout/stderr ? Shall we put a big fat warning ? Shall we make
gst_poll_add_fd return false for 0/1/2 fds ?

P.S. Steve, if you read this, just die ! sorry, I meant iDie (available with
the latest iSuicide and it's iFailure extension pack)
