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.
