As a result, the limbo entry stayed in the limbo, and after the transaction termination turned into garbage, because was allocated on its region; - txn_limbo_ack() had the same problem - completed transaction should be removed from limbo. diff --git a/src/box/txn_limbo.c b/src/box/txn_limbo.c index 3b9aa6d40..f38639676 100644 --- a/src/box/txn_limbo.c +++ b/src/box/txn_limbo.c @@ -123,8 +123,10 @@ txn_limbo_wait_complete(struct txn_limbo *limbo, struct txn_limbo_entry *entry) assert(entry->lsn > 0); assert(!txn_has_flag(txn, TXN_IS_DONE)); assert(txn_has_flag(txn, TXN_WAIT_ACK)); - if (txn_limbo_check_complete(limbo, entry)) + if (txn_limbo_check_complete(limbo, entry)) { + txn_limbo_remove(limbo, entry); return; + } bool cancellable = fiber_set_cancellable(false); while (!txn_limbo_entry_is_complete(entry)) fiber_yield(); @@ -144,8 +146,8 @@ txn_limbo_ack(struct txn_limbo *limbo, uint32_t replica_id, int64_t lsn) assert(limbo->instance_id != REPLICA_ID_NIL); int64_t prev_lsn = vclock_get(&limbo->vclock, replica_id); vclock_follow(&limbo->vclock, replica_id, lsn); - struct txn_limbo_entry *e; - rlist_foreach_entry(e, &limbo->queue, in_queue) { + struct txn_limbo_entry *e, *tmp; + rlist_foreach_entry_safe(e, &limbo->queue, in_queue, tmp) { if (e->lsn <= prev_lsn) continue; if (e->lsn > lsn) @@ -158,6 +160,7 @@ txn_limbo_ack(struct txn_limbo *limbo, uint32_t replica_id, int64_t lsn) // appliers will be supposed to wait for // 'confirm' message. e->is_commit = true; + rlist_del_entry(e, in_queue); fiber_wakeup(e->txn->fiber); } assert(e->ack_count <= VCLOCK_MAX);
