| | | | | | | | Changed AuxPoW parent block hashing to use Scrypt rather than SHA256 hash. Update chain parameters to match Dogecoin Move CheckProofOfWork into dogecoin.cpp and rename it to CheckAuxPowProofOfWork. Add operator overrides to CBlockVersion so that naive usage operates on the underlying version without chain ID or flags. Modify RPC mining to more closely match existing submitblock() structure

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.
* [tests] fix partition alerts for DogecoinPatrick Lodder2015-07-051-9/+9
| | | | | | | Partitioning is tested over 4h and 100 blocks are insufficient to test this for Dogecoin. We need 640 blocks in 4h for the "abnormally high" alert test, I've found a set of 800 blocks to test over providing sufficient margin.
* Further unit test correctionsRoss Nicoll2015-07-057-49/+53
| | | | | | | | | | | | | Replace RPC and deterministic signatures in unit tests with Dogecoin values. While conventionally I'd use an alternative implementation for these, as RFC 6979 compliant signature generation isn't terribly common, and there's no reason to suspect we've modified this code, I'm going to assert that it's good enough to test that the code doesn't provide different values. Correct BIP32 key headers for Dogecoin, also by repacking the data. Disabled Bitcoin PoW tests, but left code in place to simplify later merges. These are replaced by the Dogecoin PoW tests.

* Use best header chain timestamps to detect partitioningGavin Andresen2015-06-154-14/+16
| | | | | | | | | | | The partition checking code was using chainActive timestamps to detect partitioning; with headers-first syncing, it should use (and with this pull request, does use) pIndexBestHeader timestamps.

* Add option `-alerts` to opt out of alert systemWladimir J. van der Laan2015-06-153-1/+8
| | | | | | | | | | | | | Make it possible to opt-out of the centralized alert system by providing an option `-noalerts` or `-alerts=0`. The default remains unchanged. This is a gentler form of #6260, in which I went a bit overboard by removing the alert system completely. I intend to add this to the GUI options in another pull after this.

* Fix getbalance *Tom Harding2015-06-151-3/+3
| | | | | | | | | | | | | Chance "getbalance *" not to use IsTrusted. The method and result now match the "getbalance <specific-account>" behavior. In particular, "getbalance * 0" now works. Also fixed a comment -- GetGalance has required 1 confirmation for many years, and the default "getbalance *" behavior matches that.

* Prune: Support noncontiguous block filesAdam Weiss2015-06-112-19/+38
| | | | | | | | | | | | | | | | | | In some corner cases, it may be possible for recent blocks to end up in the same block file as much older blocks. Previously, the pruning code would stop looking for files to remove upon first encountering a file containing a block that cannot be pruned, now it will keep looking for candidate files until the target is met and all other criteria are satisfied. This can result in a noncontiguous set of block files (by number) on disk, which is fine except for during some reindex corner cases, so make reindex preparation smarter such that we keep the data we can actually use and throw away the rest. This allows pruning to work correctly while downloading any blocks needed during the reindex. Rebased-From: c257a8c9a6397eee40734b235a4fdcb8045aec91 Github-Pull: #6221
* Fix removing of orphan transactionsAlex Morcos2015-06-101-3/+4
| | | | | | | We don't want to erase orphans that still have missing inputs, they should still be tracked as orphans. Also, the transaction thats being accepted can't be an orphan otherwise it would have previously been accepted, so doesn't need to be added to the erase queue.

* json: fail read_string if string contains trailing garbageWladimir J. van der Laan2015-06-032-3/+21
| | | | | | | | | | | | | Change `read_string` to fail when not the entire input has been consumed. This avoids unexpected, even dangerous behavior (fixes #6223). The new JSON parser adapted in #6121 also solves this problem so in master this is a temporary fix, but should be backported to older releases. Also adds tests for the new behavior.

* Fix off-by-one error w/ nLockTime in the walletPeter Todd2015-06-018-38/+39
| | | | | | | | | | | | | | | | | | Previously due to an off-by-one error the wallet ignored nLockTime-by-height transactions that would be valid in the next block even though they are accepted into the mempool. The transactions wouldn't show up until confirmed, nor would they be included in the unconfirmed balance. Similar to the mempool behavior fix in 665bdd3b, the wallet code was calling IsFinalTx() directly without taking into account the fact that doing so tells you if the transaction could have been mined in the *current* block, rather than the next block. To fix this we strip IsFinalTx() of non-consensus-critical functionality, removing the default arguments, and add CheckFinalTx() to check if a transaction will be final in the next block.
