Services/Sync/Snippets

For want of a better place, here are some handy snippets for investigating Sync issues.

For most of these your Sync credentials and keys need to have been loaded before running (otherwise you might get errors about there being no key for a collection). Run a sync first.

Print out a list of large bookmark records

Change '1000' as appropriate.

 Components.utils.import("resource://services-sync/engines.js");
 Components.utils.import("resource://services-sync/engines/bookmarks.js");
 let bme = Engines.get("bookmarks");
 let ids = Object.keys(bme._store.getAllIDs());
 for each (let id in ids) {
   let record = bme._store.createRecord(id, "bookmarks");
   let len = record.toString().length;
   if (len > 1000) {
     console.log("ID: " + id + ", len = " + len + ", " + record.title);
   }
 }

Get a count of the number of members of a collection on the server.

Components.utils.import("resource://services-sync/main.js");
Components.utils.import("resource://services-sync/resource.js");
JSON.parse(new Resource(Weave.Service.storageURL + "passwords").get()).length;

Dump the cleartext of each record in a collection to the console.

Components.utils.import("resource://services-sync/main.js");
Components.utils.import("resource://services-sync/record.js");
let recordType = Weave.Engines.get("passwords")._recordObj;
let coll = new Collection(Weave.Service.storageURL + "passwords", recordType);
coll.full = true;
coll.recordHandler = function(item) {
  item.collection = "passwords";
  item.decrypt();
  console.log(item.cleartext);
};
coll.get();
