2018-03-15Merge #12431: Only call NotifyBlockTip when chainActive changesWladimir J. van der Laan
f98b54352 Only call NotifyBlockTip when the active chain changes (James O'Beirne) 152b7fb25 [tests] Add a (failing) test for waitforblockheight (James O'Beirne) Pull request description: This is a subset of the more controversial https://github.com/bitcoin/bitcoin/pull/12407, but this also adds a test demonstrating the bug. In InvalidateBlock, we're calling NotifyBlockTip with the now-invalid block's prev regardless of what chain the ancestor block is on. This could create numerous issues, but it at least screws up `waitforblockheight` (or anything else relying on `rpc/blockchain.cpp:latestblock`) when InvalidateBlock is called on a block not in chainActive, which can happen via RPC. Only call NotifyBlockTip when the block being marked invalid is on the active chain.

2018-02-16Only call NotifyBlockTip when the active chain changesJames O'Beirne
Previously, if `invalidateblock` was called on a block in a branch, NotifyBlockTip would be called on that block's predecessor, creating an incorrect `rpc/blockchain.cpp:latestblock` value. Only call NotifyBlockTip if the chain being modified is activeChain.

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.
