cfthread issues

[Hugh Rainey]

I'm wondering if anyone is having the same issues I'm having and if they are, have they been able to overcome them.

I've been trying to utilize cfthread in an update page that runs on my system every Monday.  I'm updating a database within the thread and only just recently realized that there is an error within the thread.  I actually don't need any help with regards to figuring out the issue, but while I was working to find the solution I came across an inconsistency.  With ACF I can use code like the following.

cfthread action=run name=thread1 {

thread1.testvar = "this is a test of the emergency system"

thread.testvar2 = "this is another test"

writeoutput(testvar)

writeoutput(testvar2)

/cfthread

writeoutput(thread1.testvar & "br")

writeoutput(thread1.testvar2)

The above ACF code outputs: "this is a test of the emergency system" and "this is another test".  

On lucee I get nothing.  I've tried testing the length of thread1.testvar using thread1.testvar.len() but it reads 0. I've also tried using thread1.output.len() and just thread1.output to see if I get something. Nada, bupkiss.  Weird thing is if I dump( thread1 ) the values for testvar and testvar2 show up.  It's only when I try to access the info directly that it doesn't read it.

If anyone has an idea on how to fix this or if Lucee has a different way to access thread information please let me know.

Are you sure the thread has finished/written those variables by the time you're accessing them?

I'd add a cfthread action=join name=thread1 after your thread block and before your writeoutput.

So I added the suggested thread action=join name=thread1 to my test code and still no bueno.  I also tried the following with no luck either.

<cfthread action="run" name="thread1" >

<cfset testvar = "This is a test of the emergency" >

<cfoutput>#testvar#</cfoutput>

</cfthread>

<cfthread action="sleep" duration="2000" />

<cfthread action="join" name="thread1"/>

<cfoutput>

Thread1 Value: #thread1.testvar# <br>

Thread1 output: #thread1.output#

</cfoutput>

Any thoughts?

I added a cfdump to show the value are there, just not accessible directly through code.

<cfthread action="run" name="thread1" >

<cfset testvar = "This is a test of the emergency" >

<cfoutput>#testvar#</cfoutput>

</cfthread>

<cfthread action="sleep" duration="2000" />

<cfthread action="join" name="thread1"/>

<cfdump var="#thread1#">

<cfoutput>

Thread1 Value: #thread1.testvar# <br>

Thread1 output: #thread1.output#

</cfoutput>
