Paul Joseph Davis resolved COUCHDB-542.
---------------------------------------
Resolution: Not A Problem
Using the callbacks for GC'ing isn't necessary as we ensure that JS_MaybeGC is
called frequently due to the Erlang timeouts on commands.
> Fix for COUCHDB-288 makes JS_MaybeGC not called
> -----------------------------------------------
>
> Key: COUCHDB-542
> URL: https://issues.apache.org/jira/browse/COUCHDB-542
> Project: CouchDB
> Issue Type: Bug
> Components: JavaScript View Server
> Reporter: Mike Hommey
>
> The fix for COUCHDB-288 only basically replaces JS_SetBranchCallback with
> JS_SetOperationCallback, which is not enough for the callback to be
> triggered. The problem is that basically, the operation callback API has now
> nothing to do with the previous branch callback API, and is not called at
> each branch call at the JS level. Actually, it is not called at all, except
> if JS_TriggerOperationCallback is used. Typically, this needs to be done
> either from a signal handler or a watchdog thread, in which case the test
> inside the callback is pretty pointless.
