* p2p: fix race causing dropped connections during syncj-berman2025-12-111-1/+2
| | | | | | | | | | | | | Without this commit: 1) read height from DB 2) add block to chain in separate thread 3) read chain for block id's and request them from peer 4) ERR in handle_response_chain_entry, peer's first block is the one that was added to the chain, which has block idx=height from step 1. This commit reads the chain for height and highest block id's in one go while holding the m_blockchain_lock to avoid the race.

* Refactored rx-slow-hash.cSChernykh2022-12-141-1/+3
| | | | | | | | | - Straight-forward call interface: `void rx_slow_hash(const char *seedhash, const void *data, size_t length, char *result_hash)` - Consensus chain seed hash is now updated by calling `rx_set_main_seedhash` whenever a block is added/removed or a reorg happens - `rx_slow_hash` will compute correct hash no matter if `rx_set_main_seedhash` was called or not (the only difference is performance) - New environment variable `MONERO_RANDOMX_FULL_MEM` to force use the full dataset for PoW verification (faster block verification) - When dataset is used for PoW verification, dataset updates don't stall other threads (verification is done in light mode then) - When mining is running, PoW checks now also use dataset for faster verification

* RPC and ZeroMQ APIs to support p2poolSChernykh2021-09-111-2/+37
| | | | | | | | | | | | | | | | | | | | Adds the following: - "get_miner_data" to RPC API - "json-miner-data" to ZeroMQ subscriber contexts Both provide the necessary data to create a custom block template. They are used by p2pool. Data provided: - major fork version - current height - previous block id - RandomX seed hash - network difficulty - median block weight - coins mined by the network so far - mineable mempool transactions

* / blockchain: fix timestamp/difficulty cache getting out of syncmoneromooo-monero2020-07-081-0/+1
|/ | | | | | | | | | | | | | | | | | The cache is discarded when a block is popped, but then gets rebuilt when the difficulty for next block is requested. While this is all properly locked, it does not take into account the delay caused by a database transaction being only committed (and thus its effects made visible to other threads) later on, which means another thread could request difficulty between the pop and the commit, which would end up using stale database view to build the cache, but that cache would not be invalidated again when the transaction gets committed, which would cause the cache to not match the new database data. To fix this, we now keep track of when the cache is invalidated so we can invalidate it again upon database transaction commit to ensure it gets calculated again with fresh data next time it is nedeed.

| * monerod can now sync from pruned blocksmoneromooo-monero2019-09-271-8/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If the peer (whether pruned or not itself) supports sending pruned blocks to syncing nodes, the pruned version will be sent along with the hash of the pruned data and the block weight. The original tx hashes can be reconstructed from the pruned txes and theur prunable data hash. Those hashes and the block weights are hashes and checked against the set of precompiled hashes, ensuring the data we received is the original data. It is currently not possible to use this system when not using the set of precompiled hashes, since block weights can not otherwise be checked for validity. This is off by default for now, and is enabled by --sync-pruned-blocks
