Minor - P4 Using setVerboseShell(true) with 'compatibility' or 'commands' writes leads to duplicate error messages in the shell. This bug seems like it will affect any caller of DBCollection.prototype._printExtraInfo.
Write Commands:
> setVerboseShell(true);
> db.test1.drop();
true
>
> db.test1.insert({_id: 'a'});
Inserted 1 record(s) in 6ms
WriteResult({ "nInserted" : 1 })
> db.test1.insert({_id: 'a'});
insertDocument :: caused by :: 11000 E11000 duplicate key error index: test.test1.$_id_ dup key: { : "a" }
WriteResult({
"nInserted" : 0,
"writeError" : {
"code" : 11000,
"errmsg" : "insertDocument :: caused by :: 11000 E11000 duplicate key error index: test.test1.$_id_ dup key: { : \"a\" }"
}
})
Compatibility mode:
> setVerboseShell(true);
> db.getMongo().forceWriteMode('compatibility');
> db.test1.drop();
false
>
> db.test1.insert({_id: 'a'});
Inserted 1 record(s) in 416ms
WriteResult({ "nInserted" : 1 })
> db.test1.insert({_id: 'a'});
insertDocument :: caused by :: 11000 E11000 duplicate key error index: test.test1.$_id_ dup key: { : "a" }
WriteResult({
"nInserted" : 0,
"writeError" : {
"code" : 11000,
"errmsg" : "insertDocument :: caused by :: 11000 E11000 duplicate key error index: test.test1.$_id_ dup key: { : \"a\" }"
}
})
Legacy mode:
> setVerboseShell(true);
> db.getMongo().forceWriteMode('legacy');
> db.test1.drop();
true
>
> db.test1.insert({_id: 'a'});
Inserted 1 record(s) in 2ms
> db.test1.insert({_id: 'a'});
insertDocument :: caused by :: 11000 E11000 duplicate key error index: test.test1.$_id_ dup key: { : "a" }
