Minor - P4 Add tests which send the extended query syntax:
{$query:{..}, $explain:true, $hint:{...}, $showDiskLoc:true, ... }
In an update to make sure they aren't supported as query options:
db.a.update({$query:{}, $explain:true}, {$set:{a:1}})
Update WriteResult({
"ok" : 1,
"nModified" : 0,
"n" : 0,
"lastOp" : Timestamp(1389888187, 1),
"writeErrors" : [
{
"index" : 0,
"code" : 17242,
"errmsg" : "could not canonicalize query { $query: {}, $explain: true }"
}
]
})
We will want to cover other query options which are not appropriate to updates if there are any.
