Cleanup a.k.a. Try/Finally

By Ritchie Annand on 27 Jan
Especially when making extensions that include resources (like file handles or locks), the current system of handling exceptions can be a bit clunky when trying to make sure those resources are repatriated.

The current pattern I am using is somewhat like this:

Try/Catch

It's awkward in large part because not only does the cleanup have to be duplicated for the regular path and all exception handlers, but there is no opportunity to "re-raise" the original exception.

Perhaps something like this would be in order?

Cleanup Alternative
That would generate a try..finally around the code, with the Cleanup part of the flowchart in the Finally section.

If the try..finally was generated *inside* the regular try..catch, then the exception handlers could also catch issues that get raised in the cleanup.
