Description
Repro:
db.test.insert({"x" : []});
|
db.test.update({}, {$max: {"x.2.a": 1, "x.2.b": 1}});
|
|
|
// 3.4: { "x" : [ null, null, { "a" : 1, "b" : 1 } ] }
|
// 3.6: { "x" : [ null, null, { "a" : 1 }, { "b" : 1 } ] }
|
The behavior on 3.6 gives the appearance that a different array element than the one specified was modified. In this case, the 3rd instead of the 2nd.
The behavior on 3.4 seems to be correct.
