Subject: SCE-API 1.0: Request for interpretation
Hi,
I sent this to Brian and Duaine back in October but it somehow
slipped through the cracks so I am resending it to the list:
Here is a question regarding SCE-API 1.0: In Section 5.2.1 on p. 36
of the SCE-API 1.0 spec it is stated that the message output port
priority "for certain implementations [...] can be used as a `hint'
to the infrastructure linker to decide which output ports to service
first". This sounds to me as if it is up to the implementation
whether to implement port priorities or not since the paragraph talks
about `certain implementations' and `hint'. So the question is: are
port priorities required to be implemented and handled correctly or
are they optional? If they are required it may be a good idea to
strengthen the language around them. If they are optional, I think
their value is questionable since the user cannot rely on them.
Second issue: Also, in the following paragraph it says "with some
*exceptions*, the port priority *generally* follows the semantics of
the UNIX nice command" (emphasis mine). The words `exceptions' and
`generally' are a bit misleading here and could be interpreted to mean
that the implementation is allowed to handle priorities differently
than described in the bullets below this sentence. My guess is that
the bullets are intended to describe the mandatory way priorities must
be handled and that the sentence is more of a background on how IKOS
and/or the ITC committee came up with this scheme. Is this correct?
Thanks,
Per
