* new blob block api method integrated into wallet * direct msg streaming of headers, rename, tests * perform_handshake call fix * updated trusted sync with new block header calls * add max blocks limit to fetch * added tests for rejected block header msgs * avoid parsing transactions info if not required * avoid looking up capabilities setting * move block tests out of a class * test fix * Merge changes * added docs and increased rate limits * increased block header request interval from 32 to 128 * remove fetching hashes and use height range * fetching by height in db v2 * update capabilities, other fixes * fixed range block header call * Add type hints * Start work on optimizing fetch_last_tx_from_peer * Huge speedup in trusted wallet sync * Revert unintentional changes * Fix trade issue * Improve the code * Str format * Optimize handling of farming rewards * Fix bug * Performance fixes * Optimizations to wallet syncing * Don't return all coins in respond_additions * Revert concurrency numbers * More optimization of the caches * Small optimization in coin_added * Optimize request_additions significantly by using a cache * fixes from feedback * capabilities check fixes * Increase rate limits to allow 250tps in verification requests * Start work on rate limits * New rate limit versioning support * Revert unrelated changes * revert return False * Lint * Revert cbi * try tests with trusted peer * Revert unrelated wallet changes * Revert more debug changes * Add test and throw on an error if not found * Reject invalid requests * Revert bad change with uint32, and change warning to info * Parametrize wallet sync test * Merge and LGTM * More clean way to choose peers * Fix lint * add the new RejectBlockHeaders, RequestBlockHeaders and RespondBlockHeaders to the network protocol regression test and regenerate test files * Rate limit diffs only * Improve performance * Simpler * Lint Co-authored-by: Sebastjan <trepca@gmail.com> Co-authored-by: arvidn <arvid@libtorrent.org>
