[Geotools-devel] [jira] (GEOT-4388) Make ContentFeatureSource thread-safe for working with concurrent J2EE transactions

Fri, 08 Feb 2013 01:15:48 -0800

Issue Type: Improvement Improvement
Assignee: Unassigned
Components: data
Created: 08/Feb/13 3:14 AM
Description:

ContentFeatureSource is currently referencing a single transaction object, causing problems when it is accessed by multiple threads that work against different transactions (a common occurrence in J2EE environments).

I propose to add an indirection, so transactions can be cached and accessed on a thread-local basis:

public abstract class ContentFeatureSource {
	public void setTransactionCache(TransactionCache transactionCache){
		this.transactionCache = transactionCache;
	}
}

public interface TransactionCache {
   // returns a thread-local transaction
   Transaction getTransaction();

}
