Subject: [9fans] Question about o/mero -> o/live event notification mechanism
Date: Tue,  1 May 2012 00:54:47 +0300	[thread overview]
Message-ID: <op.wdlltlvd7pj5eq@thinkii> (raw)

Hi,

i explore the UI of octopus and i try to understand how omero notifies the
viewers for events.
It is apparent from the documentation that the viewers "read" events from
the ui/olive file.
However, when i cat that file from the shell and "play" with a terminal a
bit, i get no data.
The terminals are updated correctly which indicates that the events are
delivered.
I checked the source of olive (port/live/live.b) and it simply reads (by
calling updateproc(fd)) the file as expected.

Obviously i am missing something important that the documentation does not
cover.
How can i read events posted by omero?

Thanks
