/** * Initial sync runs in several phases - the first 3 are as follows: * 1) fetches the last oplog entry (op_start1) on the source; * 2) copies all non-local databases from the source; and * 3) fetches and applies operations from the source after op_start1. * * This test updates and deletes a document on the source between phases 1 and 2. The * secondary will initially fail to apply the update operation in phase 3 and subsequently have * to attempt to check the source for a new copy of the document. The absence of the document on * the source indicates that the source is free to ignore the failed update operation. * */ (function() { load("jstests/replsets/libs/initial_sync_update_missing_doc.js"); load("jstests/libs/check_log.js"); const name = 'initial_sync_update_missing_doc1'; const replSet = new ReplSetTest({ name: name, nodes: 1, }); replSet.startSet(); replSet.initiate(); const primary = replSet.getPrimary(); const dbName = 'test'; var coll = primary.getDB(dbName).getCollection(name); assert.commandWorked(coll.insert({_id: 0, x: 1})); // Add a secondary node with priority: 0 and votes: 0 so that we prevent elections while // it is syncing from the primary. const secondaryConfig = { rsConfig: {votes: 0, priority: 0} }; const secondary = reInitiateSetWithSecondary(replSet, secondaryConfig); // Update and remove document on primary. updateRemove(coll, {_id: 0}); turnOffHangBeforeCopyingDatabasesFailPoint(secondary); var res = assert.commandWorked(secondary.adminCommand({replSetGetStatus: 1})); assert.eq(res.initialSyncStatus.fetchedMissingDocs, 0); var firstOplogEnd = res.initialSyncStatus.initialSyncOplogEnd; turnOffHangBeforeGettingMissingDocFailPoint(primary, secondary, name, 0 /* numFetched */); finishAndValidate(replSet, name, firstOplogEnd, 0 /* numFetched */, 0 /* numDocuments */); replSet.stopSet(); })();
