Creating a Shared context between threads

[Philippe Mouawad <ph...@gmail.com>]

Hello,
I was wondering if there is in JMeter a way to put an Object in a context
shared by all threads ?

Something like JMeterUtils.setProperty() but which would accept an Object
as value.

Wouldn't be interesting to have that ?

Hmm I guess you are right. Just a suggestion.

I didnt like this either but you guys are the one who develop JMeter, I am
usually just working my way around until a feature or a bug gets developed,
as I don't count on my coding skills to make it into the clean JMeter code.

And I'm also too lazy.. ;)

Yes, that does work, but adds quite a bit of overhead unless one
actually needs to use BeanShell.

Also it does not address the synchronisation issue.

How about the existing bsh.shared name space? I use it like this to even
share objects between thread groups in beanshell:

MyClass UI = new MyClass();
// Saving object to allow using it later for cleanup in tearDown phase.
bsh.shared.UI = UI;


Best,
Shmuel.

Re: Creating a Shared context between threads

[Philippe Mouawad <ph...@gmail.com>]

I agree with you.

I was thinking of something like:

   - Loading a file in a setup Thread group which would contain a
   Map<String, List<String>> (ID to List of IDs map), groupID <=> IDs children
   of group in a parent/child hierarchy
   - And then in regular thread group access map by ID to get List of other
   ID and use them in a Loop Controller


Use case emerged from here, but I am not saying it's the best solution to
the case presented there:

The synchronisation issues would certainly be interesting ... what is
the use case?
