* Merge AuxPoW support from NamecoreRoss Nicoll2019-07-131-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes are as below: Wrap CBlockHeader::nVersion into a new class (CBlockVersion). This allows to take care of interpreting the field into a base version, auxpow flag and the chain ID. Update getauxblock.py for new 'generate' RPC call. Add 'auxpow' to block JSON. Accept auxpow as PoW verification. Add unit tests for auxpow verification. Add check for memory-layout of CBlockVersion. Weaken auxpow chain ID checks for the testnet. Allow Params() to overrule when to check the auxpow chain ID and for legacy blocks. Use this to disable the checks on testnet. Introduce CPureBlockHeader. Split the block header part that is used by auxpow and the "real" block header (that uses auxpow) to resolve the cyclic dependency between the two. Differentiate between uint256 and arith_uint256. This change was done upstream, modify the auxpow code. Add missing lock in auxpow_tests. Fix REST header check for auxpow headers. Those can be longer, thus take that into account. Also perform the check actually on an auxpow header. Correctly set the coinbase for getauxblock results. Call IncrementExtraNonce in getauxblock so that the coinbase is actually initialised with the stuff it should be. (BIP30 block height and COINBASE_FLAGS.) Implement getauxblock plus regression test. Turn auxpow test into FIXTURE test. This allows using of the Params() calls. Move CMerkleTx code to auxpow.cpp. Otherwise we get linker errors when building without wallet. Fix rebase with BIP66. Update the code to handle BIP66's nVersion=3. Enforce that auxpow parent blocks have no auxpow block version. This is for compatibility with namecoind. See also https://github.com/namecoin/namecoin/pull/199. Move auxpow-related parameters to Consensus::Params.

* Use mempool's ancestor sort in transaction selectionSuhas Daftuar2018-01-131-16/+7
| | | | | | | Transaction selection for mining tracks ancestor feerates that are modified based on transactions that have already been selected. This commit de-duplicates the code so that the ancestor feerate sorting used by the mempool can also be directly applied to the miner.

* Remove nBlockMaxSize from miner opt struct as it is no longer used.Gregory Maxwell2017-09-181-1/+0

* Deprecate confusing blockmaxsize, fix getmininginfo outputMatt Corallo2017-09-111-3/+1
| | | | | | | | | | | * This removes block-size-limiting code in favor of GBT clients doing the limiting themselves (if at all). * -blockmaxsize is deprecated and only used to calculate an implied blockmaxweight, addressing confusion from multiple users. * getmininginfo's currentblocksize return value was returning garbage values, and has been removed, also removing a GetSerializeSize call in some block generation inner loops and potentially addressing some performance edge cases.

|\ | | | | | | ef8dfe4 Prevent block.nTime from decreasing (Mark Friedenbach)
| * Prevent block.nTime from decreasingMark Friedenbach2015-05-271-1/+1
| | | | | | | | | | | | | | | | Under some circumstances it is possible for there to be a significant, discontinuous jump in a node's clock value. On mining nodes, this can result in block templates which are no longer valid due to time-based nLockTime constraints. UpdateTime() is modified so that it will never decrease a block's nLockTime, thereby preventing such invalidations.
