Errors with Managers when Multi-Threading

Hi,

I'm using a different thread to perform a time consuming task in custom widget. So in that task, I need to use Managers to ready/write content from/to sitefinity. Now the problem is since that logic runs on a different thread I can execute the manager and I'm receiving "Missing current principal" exception. How should I resolve this?

Is there a way to access these managers under a specific user? How to achieve this?

Thanks,
Duneel

Hello Duneel,

One way to do this is to turn off security checks. This is done at the provider level. It is important to turn it on after you complete your operation. So i suggest you use try - finally block.
try

manager.Provider.SuppressSecurityChecks = true;
///Your code///

fiinally

manager.Provider.SuppressSecurityChecks = false;

I also suggest that you manually Dispose() your manager at the end of your background task - since this causes disposing of the ORM resources - database connections.

We also have a static method that you can use to run code with elevated privileges.

SystemManager.RunWithElevatedPrivilege 

Thanks, SystemManager.RunWithElevatedPrivilege was the key to our multi-threading implementation using Parallel.ForEach.

DataProviderBase.RaiseAfterEvents accesses SystemManager.CurrentHttpContext and that is null in a multi-threaded situation unless running your code under SystemManager.RunWithElevatedPrivilege.
