VSCP Boron 0.2.10 is out. Many changes and bugfixes has been added to this release. The most exciting is that the internal decision matrix of the daemon is now fully functional. This means that the VSCP daemon/server now can be use as a fully fledged sceduler on it's on. It is possible to control when things happen down to the smallest detail. If you want a a light to be on only X-mas day between 9:30 and 10:30 that is OK. If it's just a special year this should happen that is OK to. If you want a random patterns thats easy. Actions are the workers of the decision matrix. External events such as buttons pressed and internal events such as second, minute, hour events are feed into the matrix. If the conditions for the row is fulfilled the action is performed. Actions can send new events execute exteral scripts/programs, access web servers (GET/POST), send events to remote VSCP daemons, write to file, and much more. The decion matrix can be controled remotly through the TCP/IP interface to add/remove/edit rows. Variable handling are fully functional. Write measurements to a variable and read it from a web server scripts. Enjoy! /Ake |

To use a new connection each time at is needed is not a solution for
dynamic diagrams and for example a temperature widget. I have decided to
solve this on the server instead so tables can be setup on the server.
That way a new connection can be used each time data is needed.

Ok. I can look around to see if and how it's possible.

I should have removed the
$fp = $_SESSION[ $name ];
the line but I was to lazy. This line has no meaning. The handle never
gets saved. The socket is reused when the code looks like it is now.
> What are the parameters you are calling the script with?

Variable to the script is only som name script.php?name="kalle" My
hope was that by changing "kalle" to something else each widget could
keep it's own socket open. That does not appear to work.
Change localhost to "dosilos.se" if you want to test it. Or add
host=dosilos.se as a parameter

Hi.
I have not much experience with sockets in php, but I did find one
possible bug.
$fp = $_SESSION[ $name ];
if ( $debug ) echo "Retrived file handler: " . $fp . "<br>";
// The socket last opended will be reused here
$fp = pfsockopen( $host, $port );
In the last line you overwrite $fp so resource will not be the same.
Remove that line.
What are the parameters you are calling the script with?
Regards,
Andreas

Andreas,
you have much more experience in this then I have. I have tested today a
little of what we talked to previously. As I explained then I want to
keep a socket conectin open for one widget. To test this I used the
attached code. This works for one widget but I can't find a way to have
several sockets open at the same time. Do you have any
experience/knowledge here?

Yes I have added JQuery to the toolbox. Just want to understand what is
going on before I do any "heavy" stuff.

On that page you gave x widgets. Each of theese widgets do XMLHttpRequests to cgi scripts that connect the daemon and fetch data. What I would liek was a way to keep a seession to the server open between the XMLHttpRequests I have come up with two solutions to this that might be good enough. 1.)

I can create a table variable type in the daemon that can collect data and which can be read from trhough the TCP/IP interface. This could actually be a very good thing for diagrams, taböles etc as it becomes sort of RRD. Still it would have been nice if the sessin could be kept open between the calls.

Hi. Can you tell me a bit more what the problem is. Is it just the need to keep data between http sessions or do you have need to keep a TCP connection to daemon open from web server?
