We should not return transaction metadata from `getrawtransaction` in case
transaction is not in the mempool. Height shouldn't be returned from
`gettransactionheight` in case transaction is in the mempool.
Time is not really relevant for us here and we don't use this timestamp in any
way. Yet it occupies 24 bytes and we do two clock_gettime calls to get it.
Replace it with blockStamp which is going to be used in the future for
transaction retransmissions.
It allows to improve single-node TPS by another 3%.
We had a kludge for getrawtransaction to set this useless field, but
7e371588a7 broke it. Add it right into the
decoder now to fix all types of queries (getblock/getrawtransaction/gettxout).
Fixes#1392.
This error message makes no sense when shutting down the server:
2020-06-25T19:29:53.251+0300 ERROR failed to start RPC server {"error": "http: Server closed"}
And ListenAndServer is documented to always return non-nil error one of which
is http.ErrServerClosed. This should also fix the following test failure:
