Sebb closed JEXL-115.
---------------------
> Add support for asynchronous script execution and cancellation
> --------------------------------------------------------------
>
> Key: JEXL-115
> URL: https://issues.apache.org/jira/browse/JEXL-115
> Project: Commons JEXL
> Issue Type: New Feature
> Reporter: Henri Biestro
> Assignee: Henri Biestro
> Fix For: 2.1
>
>
> WHY:
> To allow proper sandboxing and let users run their own script, it is
> necessary to control the time a script is allowed to run and avoid runaway
> executions (for instance while(true); ).
> WHAT:
> Support for asynchronuous execution is usually based on
> Runnable/Callable/Future and Thread interruption. The Callable interface
> seems the most versatile so a method to transform a Script into a Callable
> seems in order. Thread interruption is in most cases an indication that must
> be checked (besides locking methods) somehow.
> HOW:
> Creating a Callable from a Script, Context (and arguments) is
> straightforward. Checking thread interruption can be performed in the
> Interpreter loop at "key" points namely getting/setting properties, calling
> methods/functions, resolving identifiers and of course, within loop
> constructs (for, while).
