| * Re-enable SuperMajority triggered activation for v2 block constraintsPatrick Lodder2015-08-101-3/+6
| | | | | | | | | | | | | | | | Start validating v2 blocks when there is a v3 supermajority, because v2 clients (1.5->1.8) had supermajority checks disabled. This is needed for future-proofing, so that a currently accepted, but invalid v2 block will also be accepted on newer nodes.

* | | Update time-based constantsRoss Nicoll2015-08-042-15/+15
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | This updated various time-based constants to more closely reflect values appropriate to Dogecoin: * Number of blocks to look back for BIP 66 enforcement is doubled on main net (to about a day and a half's worth, vs 5 days on Bitcoin), and raised to 1,000 on testnet (bringing it up to the same quantity as Bitcoin testnet). * BIP 66 enforcement cut-offs are scaled up appropriate. * Minimum number of blocks and blockchain size are increased for pruning. In comparison to Bitcoin this uses 24 hours as a minimum, rather than 48, although given blocks are rarely full this likely reflects a lot longer in reality.

| * | | Add Scrypt hash and AuxPoW header to index databaseRoss Nicoll2015-07-264-10/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add Scrypt hash and AuxPoW header to index database so that index can be validated (a check that both Litecoin and Namecoin disable for simplicity). The index format is incompatible with 1.8, as a result, however, and guidelines on performing the upgrade will need to be prepared. Given scope of the change, it may be advisable for services to prepare bootstrap files and destroy existing index databases entirely before reindexing. To discuss.

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.

| | | | | | | | | | | | | 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.

Also fixed a comment -- GetGalance has required 1 confirmation for many years, and the default "getbalance *" behavior matches that.
