Paul Joseph Davis commented on COUCHDB-542:
-------------------------------------------
The view servers are run in their own OS level process and communicated with
over stdio. Thus when we kill the process its up to the kernel to make sure all
is well. I'm toying around with refactoring couchjs so that I can work on the
command line tests. I'll look at making those changes as well and see how
things go.
> 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.
