ENABLE_P2P_DEBUGGING_API

#define ENABLE_P2P_DEBUGGING_API   1

Define this to enable debugging code in the p2p network interface. This is code that would never be executed in normal operation, but is used for automated testing (creating artificial net splits, tracking where messages came from and when)

GRAPHENE_NET_FUTURE_SYNC_BLOCKS_GRACE_PERIOD_SEC

#define GRAPHENE_NET_FUTURE_SYNC_BLOCKS_GRACE_PERIOD_SEC   (60 * 60)

We prevent a peer from offering us a list of blocks which, if we fetched them all, would result in a blockchain that extended into the future. This parameter gives us some wiggle room, allowing a peer to give us blocks that would put our blockchain up to an hour in the future, just in case our clock is a bit off.

GRAPHENE_NET_MAX_ITEMS_PER_PEER_DURING_NORMAL_OPERATION

#define GRAPHENE_NET_MAX_ITEMS_PER_PEER_DURING_NORMAL_OPERATION   1

During normal operation, how many items will be fetched from each peer at a time. This will only come into play when the network is being flooded – typically transactions will be fetched as soon as we find out about them, so only one item will be requested at a time.

No tests have been done to find the optimal value for this parameter, so consider increasing or decreasing it if performance during flooding is lacking.

Definition at line 63 of file config.hpp.

GRAPHENE_NET_MESSAGE_CACHE_DURATION_IN_BLOCKS

#define GRAPHENE_NET_MESSAGE_CACHE_DURATION_IN_BLOCKS   5

When we receive a message from the network, we advertise it to our peers and save a copy in a cache were we will find it if a peer requests it. We expire out old items out of the cache after this number of blocks go by.

Recently lowered from 30 to match the default expiration time the web wallet imposes on transactions.

Definition at line 74 of file config.hpp.

GRAPHENE_NET_MIN_BLOCK_IDS_TO_PREFETCH

#define GRAPHENE_NET_MIN_BLOCK_IDS_TO_PREFETCH   10000

Instead of fetching all item IDs from a peer, then fetching all blocks from a peer, we will interleave them. Fetch at least this many block IDs, then switch into block-fetching mode until the number of blocks we know about but haven't yet fetched drops below this
