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 106 of file validation.cpp.

◆ g_rpc_node

NodeContext* g_rpc_node

Pointer to node state that needs to be declared as a global to be accessible RPC methods.

Due to limitations of the RPC framework, there's currently no direct way to pass in state to RPC methods without globals.

Definition at line 2420 of file blockchain.cpp.

◆ NUM_GETBLOCKSTATS_PERCENTILES

constexpr int NUM_GETBLOCKSTATS_PERCENTILES = 5
static

Definition at line 22 of file blockchain.h.
