Enumeration Type Documentation

MemPoolRemovalReason

enum MemPoolRemovalReason

strong

Reason why a transaction was removed from the mempool, this is passed to the notification signal.

Enumerator
EXPIRY	Expired from mempool.
SIZELIMIT	Removed in size limiting.
REORG	Removed for reorganization.
BLOCK	Removed for block.
CONFLICT	Removed for conflict with in-block transaction.
REPLACED	Removed for replacement.

Function Documentation

TestLockPointValidity()

bool TestLockPointValidity	(	CChain &	active_chain,
		const LockPoints &	lp
	)

Test whether the LockPoints height and time are still valid on the current chain.

Variable Documentation

cs_main

RecursiveMutex cs_main

Mutex to guard access to validation specific variables, such as reading or changing the chainstate.

This may also need to be locked when updating the transaction pool, e.g. on AcceptToMemoryPool. See CTxMemPool::cs comment for details.

The transaction pool has a separate lock to allow reading from it and the chainstate at the same time.

Definition at line 138 of file validation.cpp.

MEMPOOL_HEIGHT

const uint32_t MEMPOOL_HEIGHT = 0x7FFFFFFF

static

Fake height value used in Coin to signify they are only in the memory pool (since 0.8)
