2020-09-22Add 'sequence' zmq publisher to track all block (dis)connects, mempool deltasGregory Sanders
Using the zmq notifications to avoid excessive mempool polling can be difficult given the current notifications available. It announces all transactions being added to mempool or included in blocks, but announces no evictions and gives no indication if the transaction is in the mempool or a block. Block notifications for zmq are also substandard, in that it only announces block tips, while all block transactions are still announced. This commit adds a unified stream which can be used to closely track mempool: 1) getrawmempool to fill out mempool knowledge 2) if txhash is announced, add or remove from set based on add/remove flag 3) if blockhash is announced, get block txn list, remove from those transactions local view of mempool 4) if we drop a sequence number, go to (1) The mempool sequence number starts at the value 1, and increments each time a transaction enters the mempool, or is evicted from the mempool for any reason, including block inclusion. The mempool sequence number is published via ZMQ for any transaction-related notification. These features allow for ZMQ/RPC consumer to track mempool state in a more exacting way, without unnecesarily polling getrawmempool. See interface_zmq.py::test_mempool_sync for example usage.

Windows headers define SendMessage as a macro, which leads to problems with the method name "SendMessage". To circumvent this, we rename the method to "SendZmqMessage". -BEGIN VERIFY SCRIPT- sed -i 's/SendMessage/SendZmqMessage/g' src/zmq/zmqpublishnotifier.* -END VERIFY SCRIPT-
