Creates a new parameter, -harddustlimit, that is used for testing
standard transactions. The default is set at 1/10th of the (soft)
dust limit, to be the same as the default minimum relay fee and
leave space for future improvements.
The existing dust limit (-dustlimit) is now enforcing the economic
disincentive under which each output under the limit must add
additional fee to be accepted to the mempool. Before this commit,
-dustlimit enforced both the hard and the soft limits, which
effectively removed the soft limit altogether.
The value of DEFAULT_INCREMENTAL_RELAY_FEE has never been tuned for
Dogecoin since porting from Bitcoin Core 0.14. Even though the dual
meaning of this parameter is suboptimal, it can still be tuned.
This commit sets the value to 1/10th of DEFAULT_MIN_RELAY_TX_FEE
from validation.h, which causes:
1. Mempool limiting to be performed in steps of 0.0001 DOGE/kb
instead of 0.00001 DOGE/kb
2. RBF to be accepted by the mempool if the new fee is at least
0.0001 DOGE/kb higher than the previous fee known to the
mempool
3. RBF to be cheaper than CPFP by a factor 10 (as the latter would
require a fee of more than 0.001 DOGE/kb on a subsequent bumping
transaction), to encourage mempool replacement over prioritizing
through additional transactions that need to be mined.
4. Mempool limiting to be 10x faster to reset to zero than before,
because for bitcoin, fee increments equaled their minimum fee,
but for us this was 1/100th.
mempool_tests.cpp has been reworked a bit to reflect the reality
of having a lower increment than the minimum fee, as even though
this already was the case, this was not tested correctly due to the
static values in the unit test.
* Reduce DEFAULT_FALLBACK_FEE to 1,000,000 Koinu. Note this by itself has no effect as the required fee is higher.
* Reduce wallet minimum fees to 0.01 DOGE
* Update DEFAULT_DUST_LIMIT
* Revise derived values after updating recommended fees
* Remove fee rounding from RPC tests
* Revert tests back to Bitcoin originals where possible
- transaction_tests/IsStandard was spending 0.9 DOGE
- tx_validationcache_tests/mempool_dblspend was spending 0.11 DOGE
- wallet_tests/coin_selection was completely built around spending
cents. This test has been completely reworked and redocumented
to make sense for Dogecoin
* Update miner confirmation window to 240 for Dogecoin main net, and update related values.
* Re-enable PoW tests with Dogecoin values.
* Update version bit tests based on Dogecoin mining values.
* Enable full block tests
* Fix invalidblocktest
* Move watch only address funding to immediately before it's used, so node 0 doesn't spend the output before it checks it later.
* Fix `fundrawtransaction` tests and sanitize fee calculation at the same time
* Correct resolution of chain parameters when validating tx inputs, especially from previous coinbase transactions
* Set block versions on full block tests so that the generated blocks are AuxPoW compatible
* Modify chain consensus parameters to be height aware
* Correct implementation of simplified rewards in parameters
* Correct max money
* Use base block version in IsSuperMajority() instead of full version
* Correct mining of blocks in AuxPoW tests
* Add in missing pre-AuxPoW consensus checks
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.
Replace test data with Dogecoin equivalents in the folowing tests:
* base58
* bip32
* keys
* miner
* pow
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.
Disabled Bitcoin PoW tests, but left code in place to simplify later merges. These are
replaced by the Dogecoin PoW tests.
