- * This update handler stores information about ongoing synchronization
- * attempts from distinct source replicas.
- *
- * Normally, u1db synchronization occurs during one POST request. In order to
- * split that into many serial POST requests, we store the state of each sync
- * in the server, using a document with id 'u1db_sync_state'. To identify
- * each sync attempt, we use a sync_id sent by the client. If we ever receive
- * a new sync_id, we trash current data for that source replica and start
- * over.
- *
- * We expect the following in the document body:
- *
- * {
- * 'source_replica_uid': '<source_replica_uid>',
- * 'sync_id': '<sync_id>',
- * 'seen_ids': [['<doc_id>', <at_gen>], ...], // optional

- * 'gen': <gen>,
- * 'trans_id': '<trans_id>',
- * 'changes_to_return': [[<doc_id>', <gen>, '<trans_id>'], ...]
- * ],
- * }
- *
- * The format of the final document stored on server is:
- *
- * {
- * '_id': '<str>',
- * '_rev' '<str>',
