> Ungraceful behaviour if view returns a function
> -----------------------------------------------
>
> Key: COUCHDB-354
> URL: https://issues.apache.org/jira/browse/COUCHDB-354
> Project: CouchDB
> Issue Type: Improvement
> Components: JavaScript View Server
> Environment: {"couchdb":"Welcome","version":"0.10.0a776990"}
> Reporter: Brian Candler
> Priority: Minor
> Attachments: barf.log, test_reduce_barf.rb
>
>
> If a typo in a view definition causes it to return a function instead of a
> normal value:
> * the view server crashes
> * you get a huge Erlang barf in the log with worrying messages like "OS
> process timed out" and "brutal kill"
> I got all this just by accidentally writing "vs.shift" instead of "vs.shift()"
> The fundamental problem is that a function cannot be serialised in toJSON,
> but the error message is not helpful:
> OS Process Log Message: Error converting object to JSON: TypeError:
> {Array:function (v) {var ... snip loads ... "Object"] is not a function
> When actually the problem is that the object I was trying to convert *was* a
> function :-)
> I will attach some code which replicates this, and the barf generated.
> Of course this is entirely down to user error in an invalid map/reduce
> function. However there's already a clean error for 'undefined', maybe this
> could be done for 'function' too (or indeed any non-serialisable entity)
