RE: [Zope] Threads in ExternalMethods

11 May 2001

      Yes, I have fired off a new thread and passed it in the contructor the self
variable. It seems to be problems in referencing other zope methods from
within the new started thread.

Here is my example, I call the listaArticulos method:

def listaArticulos(self, REQUEST, RESPONSE):

    generando = GenerarEnviarListaPrecios(self, REQUEST, RESPONSE)
    generando.start()
    return 1

def longProcess(context):
    # long process for example:
    return context.context.myZopeSqlMethod()

class GenerarEnviarListaPrecios(Thread):
    def __init__(self, context, REQUEST, RESPONSE):
        Thread.__init__(self)
        self.context = context
        self.REQUEST = REQUEST
        self.RESPONSE = RESPONSE

    def run(self):
        result = longProcess(self.context)
        .... mail result ....
        return
...

Hi Juan... you need to either fire off a new process or a new thread.  See
the Python documentation for more info about how to do this (the
threading,
thread, and os modules).

Subject: [Zope] Threads in ExternalMethods
...
Hi all,
I am now trying to create an ExternalMethod that executes a long process
(about 30 seconds) in a new thread and then this thread sends the result
per
e-mail. The ExternalMethod must return inmediatly. I need this
behavior in
order to not block the user while browsing.
Are there anybody that can help me?
