Latest version of rollback log would be correct for * last checkpoint if it completed, but version of rollback log needed * is for last complete checkpoint. * Fix: When opening rollback log for recovery, do not use latest, but use * latest that is no newer than last complete checkpoint. * Test: begin txn * insert * commit * complete checkpoint (no live txns in checkpoint) * begin txn * insert * begin checkpoint (txn in checkpointed rollback log) * crash using callback2 (just before checkpoint_end is written to disk) * attempt to recover, should crash with 3113 */ static const int envflags = DB_INIT_MPOOL|DB_CREATE|DB_THREAD |DB_INIT_LOCK|DB_INIT_LOG|DB_INIT_TXN|DB_PRIVATE; static const char *namea="a.db"; static DB_ENV *env; static bool do_test=false, do_recover=false; static void checkpoint_callback_2(void * UU(extra)) { toku_hard_crash_on_purpose(); } static void run_test(void) { int r; toku_os_recursive_delete(TOKU_TEST_FILENAME); toku_os_mkdir(TOKU_TEST_FILENAME, S_IRWXU+S_IRWXG+S_IRWXO); r = db_env_create(&env, 0); CKERR(r); r = env->open(env, TOKU_TEST_FILENAME, envflags, S_IRWXU+S_IRWXG+S_IRWXO); CKERR(r); DB *db; r = db_create(&db, env, 0); CKERR(r); r = db->open(db, NULL, namea, NULL, DB_BTREE, DB_AUTO_COMMIT|DB_CREATE, 0666); CKERR(r); DB_TXN *txn; r = env->txn_begin(env, NULL, &txn, 0); CKERR(r); { DBT k,v; dbt_init(&k, "a", 2); dbt_init(&v, "a", 2); r = db->put(db, txn, &k, &v, 0); CKERR(r); uint8_t gid[DB_GID_SIZE]; memset(gid, 0, DB_GID_SIZE); gid[0]=42; r = txn->prepare(txn, gid); CKERR(r); } r = env->txn_checkpoint(env, 0, 0, 0); CKERR(r); DB_TXN *txn2; { r = env->txn_begin(env, NULL, &txn2, 0); CKERR(r); DBT k,v; dbt_init(&k, "b", 2); dbt_init(&v, "b", 2); r = db->put(db, txn2, &k, &v, 0); CKERR(r); } // cause crash at next checkpoint, after xstillopen written, before checkpoint_end is written db_env_set_checkpoint_callback2(checkpoint_callback_2, NULL); // checkpoint, putting xstillopen in recovery log (txn is still active) r = env->txn_checkpoint(env, 0, 0, 0); CKERR(r); } static void run_recover (void) { int r; r = db_env_create(&env, 0); CKERR(r); r = env->open(env, TOKU_TEST_FILENAME, envflags + DB_RECOVER, S_IRWXU+S_IRWXG+S_IRWXO); CKERR(r); // recover the prepared transaction and commit it DB_PREPLIST l[1]; long count=-1; CKERR(env->txn_recover(env, l, 1, &count, DB_FIRST)); printf("%s:%d count=%ld\n", __FILE__, __LINE__, count); assert(count==1); assert(l[0].gid[0]==42); r = l->txn->commit(l->txn, 0); CKERR(r); r = env->close(env, 0); CKERR(r); exit(0); } static void test_parse_args (int argc, char * const argv[]) { int resultcode; char * cmd = argv[0]; argc--; argv++; while (argc>0) { if (strcmp(argv[0], "-v") == 0) { verbose++; } else if (strcmp(argv[0],"-q")==0) { verbose--; if (verbose<0) verbose=0; } else if (strcmp(argv[0], "--test")==0) { do_test=true; } else if (strcmp(argv[0], "--recover") == 0) { do_recover=true; } else if (strcmp(argv[0], "-h")==0) { resultcode=0; do_usage: fprintf(stderr, "Usage:\n%s [-v|-q]* [-h] {--test | --recover } \n", cmd); exit(resultcode); } else { fprintf(stderr, "Unknown arg: %s\n", argv[0]); resultcode=1; goto do_usage; } argc--; argv++; } } int test_main (int argc, char * const argv[]) { test_parse_args(argc, argv); if (do_test) run_test(); else if (do_recover) run_recover(); return 0; }
