2020-10-12Reduce MAX_PEER_TX_ANNOUNCEMENTS for non-PF_RELAY peersPieter Wuille
Maintaining up to 100000 INVs per peer is excessive, as that is far more than fits in a typical mempool. Also disable the "overload" penalty for PF_RELAY peers.
2020-10-12Change transaction request logic to use txrequestPieter Wuille
This removes most transaction request logic from net_processing, and replaces it with calls to a global TxRequestTracker object. The major changes are: * Announcements from outbound (and whitelisted) peers are now always preferred over those from inbound peers. This used to be the case for the first request (by delaying the first request from inbound peers), and a bias afters. The 2s delay for requests from inbound peers still exists, but after that, if viable outbound peers remain for any given transaction, they will always be tried first. * No more hard cap of 100 in flight transactions per peer, as there is less need for it (memory usage is linear in the number of announcements, but independent from the number in flight, and CPU usage isn't affected by it). Furthermore, if only one peer announces a transaction, and it has over 100 in flight and requestable already, we still want to request it from them. The cap is replaced with an additional 2s delay (possibly combined with the existing 2s delays for inbound connections, and for txid peers when wtxid peers are available). Includes functional tests written by Marco Falke and Antoine Riard.

2020-08-06refactor: test: use _ variable for unused loop countersSebastian Falbesoner
substitutes "for x in range(N):" by "for _ in range(N):" indicates to the reader that a block is just repeated N times, and that the loop counter is not used in the body
2020-07-19test: Use wtxid relay generally in functional testsFabian Jahr
2020-07-19Delay getdata requests from peers using txid-based relaySuhas Daftuar
Using both txid and wtxid-based relay with peers means that we could sometimes download the same transaction twice, if announced via two different hashes from different peers. Use a heuristic of delaying txid-peer-getdata requests by 2 seconds, if we have at least one wtxid-based peer.

2019-06-19[qa] Test that getdata requests work as expectedSuhas Daftuar
We should eventually request a transaction from all peers that announce it (assuming we never receive it). We should prefer requesting from outbound peers over inbound peers. Enforce the max tx requests in flight, and the eventual expiry of those requests. Test author: Suhas Daftuar <sdaftuar@gmail.com> Adjusted by: MarcoFalke
