(Matt Corallo) ff3a219 Call RewindBlockIndex even if we're about to run -reindex-chainstate (Matt Corallo) b0f3249 More user-friendly error message if UTXO DB runs ahead of block DB (Matt Corallo) eda888e Fix some LoadChainTip-related init-order bugs. (Matt Corallo) Pull request description: This does a number of things to clean up chainstate init order, fixing some issues as it goes: * 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 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. It couldn't do anything useful as chainActive.Tip() would be null at this point anyway.

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.

I think it should be changed to this maybe. ```` if (nCheckDepth <= 0 || nCheckDepth > chainActive.Height()) nCheckDepth = chainActive.Height(); ```` Which gets rid of that huge number which is confusing for any other altcoins that have a different block time.

2017-07-14Remove confusing MAX_BLOCK_BASE_SIZE.Gregory Maxwell
Some people keep thinking that MAX_BLOCK_BASE_SIZE is a separate size limit from the weight limit when it fact it is superfluous, and used in early tests before the witness data has been validated or just to compute worst case sizes. The size checks that use it would not behave any differently consensus wise if they were eliminated completely. Its correct value is not independently settable but is a function of the weight limit and weight formula. This patch just eliminates it and uses the scale factor as required to compute the worse case constants. It also moves the weight factor out of primitives into consensus, which is a more logical place for it.

2017-06-27Make check to distinguish between orphan txs and old txs more efficient.Alex Morcos
Checking for the existence in the CCoinsViewCache of the outputs of a new tx will result in a disk hit for every output since they will not be found. On the other hand if those outputs exist already, then the inputs must also have been missing, so we can move this check inside the input existence check so in the common case of a new tx it doesn't need to run. The purpose of the check is to avoid spamming the orphanMap with slightly old txs which we have already seen in a block, but it is already only optimistic (depending on the outputs not being spent), so make it even more efficient by only checking the cache and not the entire pcoinsTip.
2017-06-26Dont create pcoinsTip until after ReplayBlocks.Matt Corallo
This requires that we not access pcoinsTip in InitBlockIndex's FlushStateToDisk (so we just skip it until later in AppInitMain) and the LoadChainTip in LoadBlockIndex (which there is already one later in AppinitMain, after ReplayBlocks, so skipping it there is fine). Includes some simplifications by Suhas Daftuar and Pieter Wuille.

2017-06-07Do not print soft-fork-script warning with -promiscuousmempoolMatt Corallo
2017-06-07Cache full script execution results in addition to signaturesMatt Corallo
This adds a new CuckooCache in validation, caching whether all of a transaction's scripts were valid with a given set of script flags. Unlike previous attempts at caching an entire transaction's validity, which have nearly universally introduced consensus failures, this only caches the validity of a transaction's scriptSigs. As these are pure functions of the transaction and data it commits to, this should be much safer. This is somewhat duplicative with the sigcache, as entries in the new cache will also have several entries in the sigcache. However, the sigcache is kept both as ATMP relies on it and because it prevents malleability-based DoS attacks on the new higher-level cache. Instead, the -sigcachesize option is re-used - cutting the sigcache size in half and using the newly freed memory for the script execution cache. Transactions which match the script execution cache never even have entries in the script check thread's workqueue created. Note that the cache is indexed only on the script execution flags and the transaction's witness hash. While this is sufficient to make the CScriptCheck() calls pure functions, this introduces dependancies on the mempool calculating things such as the PrecomputedTransactionData object, filling the CCoinsViewCache, etc in the exact same way as ConnectBlock. I belive this is a reasonable assumption, but should be noted carefully. In a rather naive benchmark (reindex-chainstate up to block 284k with cuckoocache always returning true for contains(), -assumevalid=0 and a very large dbcache), this connected blocks ~1.7x faster.
