Terminate a cfthread doesn't work

[Anders Thulin]

Hi.

I have a problem with a long running thread  want to be able to terminate while its running.

The task uses cfthread to re-schedule it self after performing n number of sub-tasks and can be running for days.

This part works well, but hen trying to terminate the thread from another script i get this error:

there is no thread running with the name [longrunning_thread] at lucee.runtime.tag.ThreadTag.doTerminate(...

To reproduce this error, consider these two scripts:

script 1:

<! this script is running 30 times during a period of 30s ->

<cfparam name="request.count" default="0">

<cfthread name="longrunning_thread" action="run"> 

    <cfscript> 

        sleep(1000); 

        request.count++; 

    </cfscript>

    <cfif request.count LT 30>

        <cfhttp url="[url]/thread.cfm?count=#request.count#" redirect="yes" resolveurl="no" throwonerror="yes" timeout="3600" />

    </cfif> 

</cfthread>

script 2:

<! should terminate the running thread ->

<cfthread name="longrunning_thread" action="terminate" />

Is this a bug or am I doing something wrong?

I don't think another thread (script 2) can see or terminate a thread started by script 1, although I must admit I'm not sure.

Anyway, for your use case I would create a gateway. They're quite easy to implement, see this page on the Railo wiki: https://github.com/getrailo/railo/wiki/Create-your-own-Event-Gateway-type

I did some work around managing threads started with CFThread from within other processes. I blogged about it here: http://domwatson.codes/2015/01/manipulating-railo-cfthreads.html. We use it to be able to terminate and monitor scheduled tasks from our own scheduled task manager.
