- Fix an erroneous high fee penalty that peers could incur for sending
older transactions.
- Update to the fees charged for imposing a load on the server.
- Prevent the relaying of internal pseudo-transactions.
- Before: Pseudo-transactions received from a peer will fail the signature
check, even if they were requested (using TMGetObjectByHash), because
they have no signature. This causes the peer to be charge for an
invalid signature.
- After: Pseudo-transactions, are put into the global cache
(TransactionMaster) only. If the transaction is not part of
a TMTransactions batch, the peer is charged an unwanted data fee.
These fees will not be a problem in the normal course of operations,
but should dissuade peers from behaving badly by sending a bunch of
junk.
- Improve logging: include the reason for fees charged to a peer.
