9ad6746ccd Use static_cast instead of C-style casts for non-fundamental types (practicalswift) Pull request description: A C-style cast is equivalent to try casting in the following order: 1. `const_cast(...)` 2. `static_cast(...)` 3. `const_cast(static_cast(...))` 4. `reinterpret_cast(...)` 5. `const_cast(reinterpret_cast(...))` By using `static_cast<T>(...)` explicitly we avoid the possibility of an unintentional and dangerous `reinterpret_cast`. Furthermore `static_cast<T>(...)` allows for easier grepping of casts. For a more thorough discussion, see ["ES.49: If you must use a cast, use a named cast"](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#es49-if-you-must-use-a-cast-use-a-named-cast) in the C++ Core Guidelines (Stroustrup & Sutter).

2018-02-06Fix fast-shutdown crash if genesis block was not loadedMatt Corallo
If the ShutdownRequested() check at the top of ActivateBestChain() returns false during initial genesis block load we will fail an assertion in UTXO DB flush as the best block hash IsNull(). To work around this, we move the check until after one round of ActivateBestChainStep(), ensuring the genesis block gets connected.

The main split was a big step, but validation.cpp is still a somewhat ranomly-mixed bag of functions that are pure functions which validate inputs (which should probably either merge with their callers or move into another file in consensus/), read/write data from disk, manipulate our current chain state (which moves into CChainState), and do mempool transaction validation. Obviously this is only a small step, but some effort is made to clean up what functions the functions in CChainState call, and obviously as things are added its easy to keep clear "CChainState::* cannot call anything except via callbacks through CValidationInterface, pure functions, or disk read/write things". Right now there are some glaring violations in mempool callbacks, and general flushing logic needs cleaning up (FlushStateToDisk maybe shouldnt be called, and there should be an API towards setDirtyBlockIndex, but I'll leave that for after @sipa's current changesets land).

(Karl-Johan Alm) Pull request description: [Reviewer hint: use [?w=1](https://github.com/bitcoin/bitcoin/pull/10275/files?w=1) to avoid seeing a bunch of indentation changes.] Presuming a user knows the block hash of the block containing a given transaction, this PR allows them to fetch the raw transaction, even without `-txindex`. It also enables support for getting transactions that are in orphaned blocks. Note that supplying a block hash will override mempool and txindex support in `GetTransaction`. The rationale behind this is that a transaction may be in multiple places (orphaned blocks) and if the user supplies an explicit block hash it should be adhered to. ```Bash $ # a41.. is a tx inside an orphan block ..3c6f.. -- first try getting it normally $ ./bitcoin-cli getrawtransaction a41e66ee1341aa9fb9475b98cfdc1fe1261faa56c0a49254f33065ec90f7cd79 1 error code: -5 error message: No such mempool transaction.

It uses our existing on-load mapBlockIndex walk to make sure everything that descends from an invalid block is marked as such, and then simply caches blocks which we attempted to connect but which were found to be invalid.

2017-10-31Reject headers building on invalid chains by tracking invalidityMatt Corallo
This tracks the set of all known invalid-themselves blocks (ie blocks which we attempted to connect but which were found to be invalid). This is used to cheaply check if new headers build on an invalid chain. While we're at it we also resolve an edge-case in invalidateblock on pruned nodes which results in them needing a reindex if they fail to reorg.

A peer could try to waste our resources by sending us unrequested blocks with low work, eg to fill up our disk. Since e2652002b6011f793185d473f87f1730c625593b we no longer request blocks until we know we're on a chain with more than nMinimumChainWork (our anti-DoS threshold), but we would still process unrequested blocks that had more work than our tip. This commit fixes that behavior.

as 'already there' 258d33b41 [mempool] Mark unaccepted txs present in mempool as 'already there'. (Karl-Johan Alm) Pull request description: I was investigating the reasons for failed imports in mempool and noticed that `LoadMempool()` and `pwallet->postInitProcess()` (for all wallets) are executed concurrently. The wallet will end up importing transactions that `LoadMempool()` later tries to import; the latter will fail due to the tx already being in the mempool. This PR changes the log message, adding an additional "already there" entry. For transactions not accepted into mempool, a check if they are in the mempool is done first, and if found, they are counted as 'already there', otherwise counted as 'failed'. Also slight rewording for consistency (successes, failed, expired, ... -> succeeded, failed, expired).

This runs Block{Connected,Disconnected}, SetBestChain, Inventory, and TransactionAddedToMempool on the background scheduler thread. Of those, only BlockConnected is used outside of Wallet/ZMQ, and is used only for orphan transaction removal in net_processing, something which does not need to be synchronous with anything else. This partially reverts #9583, re-enabling some of the gains from #7946. This does not, however, re-enable the gains achieved by repeatedly releasing cs_main between each transaction processed.
