[Laszlo-dev] [Laszlo-user] setting timeout to longer than 30 seconds

[Henry Minsky]

Here is the flow of control for SWF data request in LPS 4

+ The constructor for LzDataset sets its timeout in this code:

    if ('timeout' in args && args.timeout) {
        this.timeout = args.timeout;
    } else {
        this.timeout = canvas.dataloadtimeout;
    }


So it default to the value of the canvas.dataloadtimeout, if no
explicit timeout init arg
is passed in.

+ In the LPS 4 world where we have the new LzHTTPDataProvider, the timeout
is passed along by LzHTTPDataProvider .doRequest() to the  SWF kernel
LzHTTPLoader object

        tloader.setTimeout(dreq.timeout);



+ This timeout gets passed in to the good old LzLoader kernel object, which gets
then gets passed  to the LzLoadQueue service.

LzHTTPLoader.prototype.setTimeout = function (timeout) {
    this.timeout = timeout;
    this.lzloader.timeout = timeout;
}

+ The LzLoader creates a "load request object", which happens to be a
Flash native XML object, and it sets the "timeout" property to the
LzLoader's timeout value.


+ Then the "load object" is passed to LzLoadQueue, which is
responsible for actually sending the data requests. The timeout
property is used to checked
by a delegate which is triggered by an LzTimer event.
