Customised Distro to run Sonata

Hi, this is Jay Freeman, volunteer programmer. I had a discussion with Jon Richards on 8 August 2012, reviewing his comments here: http://setiquest.org/wiki/index.php/Get_The_SonATA_Distro_Working

Jon suspected that there might be a startup transient with "recvfrom" getting an amount of data that was nonzero, but was not equal to the amount expected. In the current implementation of Udp::recv (see the wiki page) that would result in that method returning a meaningless value of "errno". I have been implementing a test modification of "Udp::recv" to investigate, but have had some problems. The test modification is along the lines of (psuedocode):

if( recvfrom got the expected number of bytes )
home free -- return 0 and press on
else if( recvfrom returned -1 )
errno is valid, so return it
else if( recvfrom returned 0 )
peer has closed its side of connection (shouldn't happen with udp sockets).
else
recvfrom got data, but the wrong amount -- report that condition

Before I go any further, let me reassure you all by stating firmly that I have no intention of checking anything in -- all this is in my local copy of the distro.

That said, my test implementation is clumsy, mainly because it is a debugging hack, but also because I am not getting quite the same error messages as Jon reported on the Wiki page just cited. When I try to do things, my instance of the distro seems not to get as far as his did: I get the same errors after typing "test_sonata" and before issuing "source vger-demo-xpol.tcl", but thereafter, things diverge. A key problem may be an entry in the Message / Error log window:

bmitDbQuery::error: database is turned off

In any case, in the context of Jon's report on the wiki page, what happens with me is that

(1) Udp::recv is called for the first time BEFORE I type "source vger-demo-xpol.tcl", and
(2) its call to "recvfrom" never returns. (Makes sense if it is waiting for data from a not-turned-on database...)

I am not at all sure what is going on -- my guess is that there is some simple way to turn on the database that is somehow not happening -- or perhaps a race condition of some kind.

My modification of Udp::recv follows: In it, I have implemented the if/else nest with extensive reporting, using a (static) counter for how many times Udp::recv has been called, and using a special log file in /home/sonata (since I couldn't figure out how the existing logging mechanism worked, and since I was worried that Udp::recv might be called from a process that did not have an attached terminal, so that output to the console might go to the bit bucket).

Error

static unsigned long recv_try_counter = 0;

}

I tried sending to our AWS account. It shows up in AWS as Name: empty. And when it tried to start it failed - producing the following log.

I told it ot be a "large" instance. I wonder if that is big enough?
