4aa2508 Bugfix: Use testnet RequireStandard for -acceptnonstdtxn default (Luke Dashjr) Pull request description: Fixes a bug introduced in #8855 `-acceptnonstdtxn` is a valid option only for testnet/regtest (in Core), and the help message reflects that. Currently, however, it is buggy in two ways: 1. It uses mainnet to get the default value, which doesn't make sense since the option is never available for mainnet, and the only time the option is available, is when the default is the opposite. 2. It uses the value of "require standard" directly as the default for "accept non-standard transactions", but these concepts are opposites: a negation must be performed to transform one to the other. Note the combination of these bugs results in the correct boolean output, but the logic to get there is completely wrong.

2017-08-01Check for empty coinsview instead of just-reset coinsview in initMatt Corallo
This fixes a few cases where we should be treating a restart-after- coinsviewdb-reset identically to a just-reset-coinsviewdb. Thanks to @morcos for identifying the bug.
2017-08-01Fix resume-of-reindex-after-restartMatt Corallo
This more clearly uses fReindex vs fReset to make sure we're not clearing our coinsdb needlessly when restarting after a reindex. It also makes it so that restarting after shutting down mid-reindex isn't treates specially at all during txdb loading code, as it shouldn't be.

Only create objects as needed. * More clearly document exactly what is and isn't called in -reindex and -reindex-chainstate both with comments noting calls as no-ops and by adding if guards. * Move the writing of fTxIndex to LoadBlockIndex - this fixes a bug introduced in d6af06d68aae985436cbc942f0d11078041d121b where InitBlockIndex was writing to fTxIndex which had not yet been checked (because LoadChainTip hadn't yet initialized the chainActive, which would otherwise have resulted in InitBlockIndex being a NOP), allowing you to modify -txindex without reindex, potentially corrupting your chainstate! * Rename InitBlockIndex to LoadGenesisBlock, which is now a more natural name for it. Also check mapBlockIndex instead of chainActive, fixing a bug where we'd write the genesis block out on every start. * Move LoadGenesisBlock further down in init. This is a more logical location for it, as it is after all of the blockindex-related loading and checking, but before any of the UTXO-related loading and checking. * Give LoadChainTip a return value - allowing it to indicate that the UTXO DB ran ahead of the block DB. This just provides a nicer error message instead of the previous mysterious assert(!setBlockIndexCandidates.empty()) error. * Calls ActivateBestChain in case we just loaded the genesis block in LoadChainTip, avoiding relying on the ActivateBestChain in ThreadImport before continuing init process. * Move all of the VerifyDB()-related stuff into a -reindex + -reindex-chainstate if guard.

2017-07-27Order chainstate init more logically.Matt Corallo
* Order chainstate init more logically - first all of the blocktree-related loading, then coinsdb, then pcoinsTip/chainActive. Only create objects as needed. * More clearly document exactly what is and isn't called in -reindex and -reindex-chainstate both with comments noting calls as no-ops and by adding if guards. * Move LoadGenesisBlock further down in init.

2017-07-27Call RewindBlockIndex even if we're about to run -reindex-chainstateMatt Corallo
RewindBlockIndex works over both chainActive - disconnecting blocks from the tip that need witness verification - and mapBlockIndex - requiring redownload of blocks missing witness data. It should never have been the case that the second half is skipped if we're about to run -reindex-chainstate.
2017-07-27More user-friendly error message if UTXO DB runs ahead of block DBMatt Corallo
This gives LoadChainTip a return value - allowing it to indicate that the UTXO DB ran ahead of the block DB. This just provides a nicer error message instead of the previous mysterious assert(!setBlockIndexCandidates.empty()) error. This also calls ActivateBestChain in case we just loaded the genesis block in LoadChainTip, avoiding relying on the ActivateBestChain in ThreadImport before continuing init process.

Nearly every x86_64 CPU supports SSE4. The feature is only enabled when compiled with `--enable-experimental-asm`. In order to avoid build dependencies and other complications, the original Intel YASM code was translated to GCC extended asm syntax. This gives around a 50% speedup on the SHA256 benchmark for me. It is based on an earlier patch by @laanwj, though only includes a single assembly version (for now), and removes the YASM dependency.

f4d00e6 Add a discard_rate (Alex Morcos) b138585 Remove factor of 3 from definition of dust. (Alex Morcos) Pull request description: The definition of dust is redefined to remove the factor of 3. Dust is redefined to be the value of an output such that it would cost that value in fees to (create and) spend the output at the dust relay rate. The previous definition was that it would cost 1/3 of the value. The default dust relay rate is correspondingly increased to 3000 sat/kB so the actual default dust output value of 546 satoshis for a non-segwit output remains unchanged. This commit is a refactor only unless a dustrelayfee is passed on the commandline in which case that number now needs to be increased by a factor of 3 to get the same behavior. -dustrelayfee is a hidden command line option. Note: It's not exactly a refactor due to edge case changes in rounding as evidenced by the required change to the unit test. A discard_rate is added which defaults to 10,000 sat/kB Any change output which would be dust at the discard_rate you are willing to discard completely and add to fee (as well as continuing to pay the fee that would have been needed for creating the change) This would be a nice addition for 0.15 and I think will remain useful for 0.16 with the new coin selection algorithms in discussion, but its not crucial. It does add translation strings, but we could (should?) avoid that by hiding the option Tree-SHA512: 5b6f655354d0ab6b8b6cac1e8d1fe3136d10beb15c6d948fb15bfb105155a9d03684c6240624039b3eed6428b7e60e54216cc8b2f90c4600701e39f646284a9b
