Detailed Description

CTxMemPool stores valid-according-to-the-current-best-chain transactions that may be included in the next block.

Transactions are added when they are seen on the network (or created by the local node), but not all transactions seen are added to the pool. For example, the following new transactions will not be added to the mempool:

CTxMemPool::mapTx, and CTxMemPoolEntry bookkeeping:

mapTx is a boost::multi_index that sorts the mempool on 4 criteria:

Note: the term "descendant" refers to in-mempool transactions that depend on this one, while "ancestor" refers to in-mempool transactions that a given transaction depends on.

In order for the feerate sort to remain correct, we must update transactions in the mempool when new descendants arrive. To facilitate this, we track the set of in-mempool direct parents and direct children in mapLinks. Within each CTxMemPoolEntry, we track the size and fees of all descendants.

Usually when a new transaction is added to the mempool, it has no in-mempool children (because any such children would be an orphan). So in addUnchecked(), we:

When a transaction is removed from the mempool, we must:

These happen in UpdateForRemoveFromMempool(). (Note that when removing a transaction along with its descendants, we must calculate that set of transactions to be removed before doing the removal, or else the mempool can be in an inconsistent state where it's impossible to walk the ancestors of a transaction.)

In the event of a reorg, the assumption that a newly added tx has no in-mempool children is false. In particular, the mempool is in an inconsistent state while new transactions are being added, because there may be descendant transactions of a tx coming from a disconnected block that are unreachable from just looking at transactions in the mempool (the linking transactions may also be in the disconnected block, waiting to be added). Because of this, there's not much benefit in trying to search for in-mempool children in addUnchecked(). Instead, in the special case of transactions being added from a disconnected block, we require the caller to clean up the state, to account for in-mempool, out-of-block descendants for all the in-block transactions by calling UpdateTransactionsFromBlock(). Note that until this is called, the mempool state is not consistent, and in particular mapLinks may not be correct (and therefore functions like CalculateMemPoolAncestors() and CalculateDescendants() that rely on them to walk the mempool are not generally safe to use).

Computational limits:

Updating all in-mempool ancestors of a newly added transaction can be slow, if no bound exists on how many in-mempool ancestors there may be. CalculateMemPoolAncestors() takes configurable limits that are designed to prevent these calculations from being too CPU intensive.

Remove a set of transactions from the mempool.

If a transaction is in this set, then all in-mempool descendants must also be in the set, unless this transaction is being removed for being in a block. Set updateDescendants to true when removing a tx that was in a block, so that any in-mempool descendants have their ancestor state updated.

Before calling removeUnchecked for a given transaction, UpdateForRemoveFromMempool must be called on the entire (dependent) set of transactions being removed at the same time.

We use each CTxMemPoolEntry's setMemPoolParents in order to walk ancestors of a given transaction that is removed, so we can't remove intermediate transactions in a chain before we've updated all the state for the removal.

UpdateForDescendants is used by UpdateTransactionsFromBlock to update the descendants for a single transaction that has been added to the mempool but may have child transactions in the mempool, eg during a chain reorg.

setExclude is the set of descendant transactions in the mempool that must not be accounted for (because any descendants in setExclude were added to the mempool after the transaction being updated and hence their state is already reflected in the parent state).

cachedDescendants will be updated with the descendants of the transaction being updated, so that future invocations don't need to walk the same transaction again, if encountered in another transaction chain.

void CTxMemPool::UpdateForRemoveFromMempool ( const setEntries entriesToRemove,

UpdateTransactionsFromBlock() will find child transactions and update the descendant state for each transaction in vHashesToUpdate (excluding any child transactions present in vHashesToUpdate, which are already accounted for).
