Dear Ashis,
The port simply forwards the data, so when you what to "clean" it is
too late anyway.
Instead, what you could do is send a special message like 'refresh'
through the port whenever you want to wipe you log. Then, at the
receiving side in the top-level space you can write yourself a
program which, e.g., wipes your log file whenever the message
'refresh' was sent.

Thanks Filip. I am using it for kind of Logging purposes. But the port
is keeping up the logs (it's not really log for my case) from the last
run if I did not restart server. I want it to refresh the log (more
like
some diagnostic info in my case) at every run even I do not restart
the
server. Is there a simple way to clear the port?

Hi,
I am getting another hang-up here. It appears that Port is not
getting
cleaned up in subsequent runs if the underlying process does not die.
Is
there a simple way to reset the Port/Stream?
I am accessing ports from spaces without problems. Remeber, when using
this from scripts, the semantics must not break the rules of spaces -
identical queries should always return identical results. (I used this
for referencing external static data and for caching of const
calculations.) Other meaningful usages are console I/O (output) and
logging.
What exact problems are you experiencing? Isn't it that the server
thread just died? Be sure to fortify the thread using try...catch for
each message.
HTH,
Filip
Thanks so much,
Ashis

Thanks so much. I was able to solve my problem using Port.

The error message says that you are trying to modify a stateful
entity from inside a computation space. This is forbidden by the
language definition, because it breaks an essential assumption on
computations spaces: they cannot have side effects. There is an
exception to the rule, however: you can send messages on ports.
Besides, you could put a dictionary inside the script so it becomes
local.

Hi everybody,
How can I store data in a global variable (say in a Dictionary) in a
functor file so that I can export that data that can be accessed
from
another functor? Specifically, I am trying something like this
(seems
like this sandbox code doesn't even compile -- though actual code
does):
functor
import
export
define
Dict
Dict = {Dictionary.new}
proc{StoreInfo}
{Dictionary.put Dict xx yy}
end
end
The program either hangs or I get error -- "assignment of global
variable from local space" (it appears that I can do Dictionary.get
operation from local space). If I can not do it this way is there
another way I can store several key-value pairs that can be
accessed at
the end of run from another(Client) Functor?
Thanks so much.
Ashis
