Merge #13258: uint256: Remove unnecessary crypto/common.h dependency
bf2e01097 uint256: Remove unnecessary crypto/common.h use (Karl-Johan Alm)

Pull request description:

  This is an alternative to #13242 which keeps the `ReadLE64` part, but moves the `crypto/common.h` dependency into `crypto/common.h` as a function outside of `uint256`.

  **Reason:** this change will remove dependencies for `uint256` to `crypto/common.h`, `compat/endian.h`, and `compat/byteswap.h`.

  This PR removes the need to update tests to be endian-aware/-independent, but keeps the (arguably dubious) `ReadLE64` part (which was only introduced to fix the tests, not for any functionality).

e9a27cf338dc618b8ecab8984abc54d588de8a05 refactor: Remove unused COINBASE_FLAGS (Neha Narula)

Pull request description:

  Commit d449772cf6 stopped setting
  COINBASE_FLAGS, and it looks like it hasn't been used since P2SH.

  Following up on #17489, remove COINBASE_FLAGS which is unused. I verified that removing this did not change the contents of the coinbase's scriptSig.

6f6514a08090b37b5e8c086015ee4881813ef867 Correct units for "-dbcache" and "-prune" (Hennadii Stepanov)

Pull request description:

  Actually, all `dbcache`-related values in the code are measured in MiB (not in megabytes, MB) or in bytes (e.g., `nTotalCache`).

  See: https://github.com/bitcoin/bitcoin/blob/master/src/txdb.h

  ba8c8b2227/src/init.cpp (L1405-L1424)

  Also, "-prune" is fixed:
  1. The GUI values in GB are translated to the node values in MiB correctly.
  2. The maximum of the "prune" `QSpinBox` is not limited by default value of 99 (GB).

  Fix: #15106

14af9c67b6 Merge #13783: validation: Pass tx pool reference into CheckSequenceLocks
fa511e8dad Pass tx pool reference into CheckSequenceLocks (MarcoFalke)

Pull request description:

  `CheckSequenceLocks` is called from ATMP and the member function `CTxMemPool::removeForReorg` without passing in the tx pool object that is used in those function's scope and instead using the global `::mempool` instance.

  This fix should be refactoring only, since currently there is only one (global) tx pool in normal operation. Though, it fixes hard to track down issues in future settings where more than one mempool exists at a time. (E.g. for tests, rpc or p2p tx relay purposes)

Pull request description:

  I thought `whitelistrelay` default was `false` when it is `true`.

  The root of the issue come from the fact that all references to `DEFAULT_` are not in the scope of this file, so hard coding of default values are used everywhere in `net.cpp`. I think that in a separate PR we should fix that more fundamentally everywhere.

be54f42e5f309ff332d74828ae294636d77fb8ea use integer division instead of double conversion and multiplication for computing amounts (Arvid Norberg)

Pull request description:

  use integer division instead of double conversion and multiplication for computing amounts. This will most likely generate identical code.

  My main argument in favour of this change is one of purity, that we should not rely on implicit conversion from `CAmount` -> `double` and back again. Today this implicit conversion can happen because `CAmount` is just a typedef to `int64_t`. However, I envision a future where `CAmount` is a proper type that does not allow suspicious implicit conversions like these.

9e0a514112 Add compile time checking for all cs_main runtime locking assertions (practicalswift)

Pull request description:

  Add compile time checking for `cs_main` runtime locking assertions.

  This PR is a subset of #12665. The PR was broken up to make reviewing easier.

  The intention is that literally all `EXCLUSIVE_LOCKS_REQUIRED`/`LOCKS_EXCLUDED`:s added in this PR should follow either directly or indirectly from `AssertLockHeld(…)`/`AssertLockNotHeld(…)`:s already existing in the repo.

  Consider the case where function `A(…)` contains `AssertLockHeld(cs_foo)` (without
  first locking `cs_foo` in `A`), and that `B(…)` calls `A(…)` (without first locking `cs_main`):
  * It _directly_ follows that: `A(…)` should have an `EXCLUSIVE_LOCKS_REQUIRED(cs_foo)` annotation.
  * It _indirectly_ follows that: `B(…)` should have an `EXCLUSIVE_LOCKS_REQUIRED(cs_foo)` annotation.

Pull request description:

  I'm re-opening #11857 as a new pull request because the last one stopped loading for people

  -------------------------------

  This refactors the tx index code to be in it's own class and get built concurrently with validation code. The main benefit is decoupling and moving the txindex into a separate DB. The primary motivation is to lay the groundwork for other indexers that might be desired (such as the [compact filters](https://github.com/bitcoin/bips/pull/636)). The basic idea is that the TxIndex spins up its own thread, which first syncs the txindex to the current block index, then once in sync the BlockConnected ValidationInterface hook writes new blocks.

  ### DB changes

  At the suggestion of some other developers, the txindex has been split out into a separate database. A data migration runs at startup on any nodes with a legacy txindex. Currently the migration blocks node initialization until complete.

  ### Open questions

  - Should the migration of txindex data from the old DB to the new DB block in init or should it happen in a background thread? The downside to backgrounding it is that `getrawtransaction` would return an error message saying the txindex is syncing while the migration is running.

  ### Impact

  In a sample size n=1 test where I synced nodes from scratch, the average time [Index writing](https://github.com/bitcoin/bitcoin/blob/master/src/validation.cpp#L1903) was 3.36ms in master and 1.72ms in this branch. The average time between `UpdateTip` log lines for sequential blocks between 400,000 and IBD end on mainnet was 0.297204s in master and 0.286134s in this branch. Most likely this is just variance in IBD times, but I can try with some more trials if people want.

Pull request description:

  To check if a single raw transaction makes it into the current transaction pool, one had to call `sendrawtransaction`. However, on success, this adds the transaction to the mempool with no easy way to undo.

  The call `testmempoolaccept` is introduced to provide a way to solely check the result without changing the mempool state.

Pull request description:

  Since the actual block files taking up more and more space, it may be desirable to have them stored in a different location then the data directory (use case: SSD for chainstate, etc., HD for blocks).

  This PR adds a `-blocksdir` option that allows one to keep the blockfiles and the blockindex external from the data directory (instead of creating symlinks).

  I fist had an option to keep the blockindex within the datadir, but seems to make no sense since accessing the index will (always) lead to access (r/w) the block files.

25bc9615b7 Document validationinterace callback blocking deadlock potential. (Matt Corallo)

Pull request description:

  From the branches-I've-had-lying-around-and-forgot-to-PR department...

  This is a comment-only PR, but the comments point out an API quirk that isn't exactly trivial. None of our use-cases right now hit this, but if we were to call SyncWithValidationInterfaceQueue (eg to limit queue depth) in ATMP, I'm pretty sure we'd hit a deadlock there.

e9a1881b90704c6708cfba79d2208debbd4476d0 refactor: add a function for determining if a block is pruned or not (Karl-Johan Alm)

Pull request description:

  The check for whether a block is pruned or not is sufficiently obscure that it deserves a macro. It is also used in 2 places, ~~with more coming, e.g. #10757~~ (turns out it was a move, not an addition).

Pull request description:

  This is an alternative to #11694.

  It reintroduces a uint256 variable with the best block hash, protected by csBestBlock, and only updated while holding it.

  Also rename the involved variable to modern guidelines, as there are very few uses.

d45b344ffd Bucket for inbound when scheduling invs to hide tx time (Gleb)

Pull request description:

  It has been brought up to my attention that current random delays mechanism (originally intended to obfuscate transaction metadata) allows to easily estimate the time a transaction was received by a node.

  It may be done by connecting multiple observer nodes to the same node. Each of those nodes will generate its own schedule of delays. Combined metadata regarding those events from different sources allows an observer to estimate transaction time.

  After this patch a spy won't gain additional information by just creating multiple connections to a target.

Backport 10279 (#3394)
* Merge #10279: Add a CChainState class to validation.cpp to take another step towards clarifying internal interfaces

22fddde Avoid calling GetSerializeSize on each tx in a block if !fTxIndex (Matt Corallo)
2862aca Move some additional variables into CChainState private (Matt Corallo)
fd4d80a Create initial CChainState to hold chain state information (Matt Corallo)
e104f0f Move block writing out of AcceptBlock (Matt Corallo)
50701ba Move txindex/undo data disk location stuff out of ConnectBlock (Matt Corallo)
93a34cf Make DisconnectBlock unaware of where undo data resides on disk (Matt Corallo)

Pull request description:

  CChainState should eventually, essentially, be our exposed "libconsensus", but we're probably a few releases away, so the real goal is to clarify our internal interfaces. 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).

Merge #11309: Minor cleanups for AcceptToMemoryPool
bf64c3cb3 Ignore transactions added to mempool during a reorg for fee estimation purposes. (Alex Morcos)
04f78ab5b Do not reject based on mempool min fee when bypass_limits is set. (Alex Morcos)
fd849e1b0 Change AcceptToMemoryPool function signature (Alex Morcos)

Pull request description:

  First commit just removes default arguments from `AcceptToMemoryPool` and consolidates two arguments, it does not change behavior.

  Second commit finally fixes the fact that we're not meant to reject based on mempool min fee when adding a transaction from a disconnected block during a reorg as mentioned [here](https://github.com/bitcoin/bitcoin/pull/9602#issue-202197849)

  Third commit makes fee estimation ignore transactions added from a disconnected block during a reorg. I think this was another source of fee estimates returning estimates below 1000 sat/kB as in #11303.

  Use `std::unique_ptr` (C++11) where possible.

  Rationale:
  1. Avoid resource leaks (specifically: forgetting to `delete` an object created using `new`)
  2. Avoid undefined behaviour (specifically: double `delete`:s)

  **Note to reviewers:** Please let me know if I've missed any obvious `std::unique_ptr` candidates. Hopefully this PR should cover all the trivial cases.

b167951 [rpc] Allow getrawtransaction to take optional blockhash to fetch transaction from a block directly. (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
