ALL
Here are examples of upserts that crash mongod:
1)
> db.x.drop();
> db.x.update( { "a": {}, "a.c": 2 } , { $set : { x: 1 } }, true , false )
2)
> db.x.drop();
> db.x.update( { "a.b": 1, "a.c": 2 } , { $set: {x: 1} }, true , false )
These do NOT cause a segfault when the upsert flag is set to false. There is also no crash if there are no conflicting fields in the query document, as in this example:
> db.x.drop()
> db.x.update( { "a.b": 1, "c.d": 2 } , { $set: {x: 1} }, true , false )
Example stack trace from mongod when it crashes:
