Currently, scan_checked_replset.js parses namespaces from documents by splitting the namespace on a period ".".
let [dbName, collName] = doc.namespace.split('.', 2);
This is problematic for collections that contain periods in the collection name, e.g:
admin.system.users config.system.sessions
This leads to the script attempting to scan on partial namespaces:
{
"msg" : "Scanning range",
"range" : {
"_id" : {
"db" : "admin",
"collection" : "system",
"minKey" : { "$minKey" : 1 },
"maxKey" : { "$maxKey" : 1 }
}
}
}
{
"msg" : "Scanning range",
"range" : {
"_id" : {
"db" : "config",
"collection" : "system",
"minKey" : { "$minKey" : 1 },
"maxKey" : { "$maxKey" : 1 }
}
}
}
We can fix this by ensuring that the full collection name is not split against by slicing on the first occurrence of a "."
let i = doc.namespace.indexOf(".")
let [dbName, collName] = [doc.namespace.slice(0,i), doc.namespace.slice(i+1)];
