Bob Lantz cece39e439 Fix poller to only check if stdin and node are readable. 
Thanks to James Zeng for pointing this out!

Bob Lantz cfd381134f Fix errRun to not exit until all of stdout and stderr have been read. 2012-05-09 22:59:30 -07:00
Bob Lantz 55cf19c4de Improve error handling for defaultDpid() 
I think it's worth considering how we want to specify dpids for
switches. One way would be to have Mininet (optionally) pick them
automatically. Another way, which I have currently implemented, is
to intuit them from the name, for example s1 -> 1. The latter is
slightly inefficient, but is convenient because it ensures that
there is a logical mapping between switch names and dpids, which
is very helpful for debugging an OpenFlow system!

Probably we should just clarify that the easiest way to set a dpid
is to include it in the switch name, but you can also pass it in
as a custom parameter to the constructor.

Bob Lantz e1246c3741 Simplify port specification. 
For the moment, I've removed the ability to specify
a dict of options without using **. This is a slightly
unfortunate trade-off since it simplifies implementation
at the expense of making the API slightly less convenient
(if somewhat more consistent.)

Bob Lantz 44af37bc2b Change default period to 100 ms, which seems to help cfs at least... 
rt is still somewhat broken.

Bob Lantz 28833d864c Retry deleting cgroup for the moment because it seems flaky.

delete at the end.

Bob Lantz efc991547e Add warning in defaultIntf() if host has no interfaces.
