Pull request description:

  Both the chain state and the transaction pool are validation specific, but access to them is protected by two locks. The two locks have the following semantics:

  * Writing to the chain state or adding transactions to the transaction pool -> Take both `cs_main` and `mempool::cs`
  * Reading either or removing transactions from the the transaction pool -> Take only the appropriate lock

Merge #13910: Log progress while verifying blocks at level 4
e58985c916 Log progress while verifying blocks at level 4. (Daniel Kraft)

Pull request description:

  When verifying blocks at startup, the progress is printed in 10% increments to logs.  When `-checklevel=4`, however, the second half of the verification (connecting the blocks again) does not log the progress anymore.  (It is still computed and shown in the UI, but not printed to logs.)

  This change makes the behaviour consistent, by adding the missing progress logging also for level-4 checks.

2196c51821 refactor: Use boost::scoped_connection in signal/slot, also prefer range-based loop instead of std::transform (Chun Kuan Lee)

Pull request description:

  Replace boost::bind with std::bind

  - In `src/rpc/server.cpp`, replace `std::transform` with simple loop.
  - In `src/validation.cpp`, store the `boost::signals2::connection` object and use it to disconnect.
  - In `src/validationinterface.cpp`, use 2 map to store the `boost::signals2::scoped_connection` object.

Merge #13930: doc: Better explain GetAncestor check for m_failed_blocks in AcceptBlockHeader
66e15e8f97 Explain GetAncestor check for m_failed_blocks in AcceptBlockHeader (Sjors Provoost)

Pull request description:

  Salvaged (but slightly modified) from #12138, the comment there was really helpful to wrap my head around that part of the code.

  In addition, a naive reader like yours truly will first think `IsValid(BLOCK_VALID_SCRIPTS)` means the previous block was invalid. But IIUC that's not what  it means. Instead, it means the block hasn't been checked for validity at the `BLOCK_VALID_SCRIPTS` level yet. So in that case the existing text "previous block index isn't valid" is wrong.

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)

Merge #14214: convert C-style (void) parameter lists to C++ style ()
3ccfa34b32 convert C-style (void) parameter lists to C++ style () (Arvid Norberg)

Pull request description:

  In C, an empty parameter list, `()`, means the function takes any arguments, and `(void)` means the function does not take any parameters.
  In C++, an empty parameter list means the function does not take any parameters.

  So, C++ still supports `(void)` parameter lists with the same semantics, why change to `()`?

  1. removing the redundant `void` improves signal-to-noise ratio of the code
  2. using `(void)` exposes a rare inconsistency in that a template taking a template `(T)` parameter list, cannot be instantiated with `T=void`

da74db0940 Drop unused GetType() from CSizeComputer (Ben Woosley)

Pull request description:

  Based on conversation in #13462, it seems the serialization `GetType` has very narrow use/effect. In every case except for `CAddress`, which specifically relates to a network peer's address, not a wallet address etc., the serialized representation of an object is irrespective of its destination / type.

  This removes the unused `GetType` method from `CSizeComputer` as a step to further narrowing that use.

Call sync.h primitives "locks" and "mutexes" instead of "blocks" and "waitable
critical sections" to match current coding conventions and c++11 standard
names.

This PR does not rename the "CCriticalSection" class (though this could be done
as a followup) because it is used everywhere and would swamp the other changes
in this PR. Plain mutexes should mostly be preferred instead of recursive
mutexes in new code anyway.

faa24441ec policy: Remove promiscuousmempoolflags (MarcoFalke)

Pull request description:

  It seems odd to clutter validation code with features that can only ever be used for testing (testnet or regtest). Removing that test-only code makes the mempool logic less painful to understand and easier to reason about when changed or refactored in the future.

Merge #13680: [doc] Remove outdated comment about miner ignoring CPFP
db6eb90094 [doc] Remove outdated comment about mining code ignoring CPFP (James O'Beirne)

Pull request description:

  BlockAssembler chooses transactions on the basis of packages (which incorporate
  unconfirmed ancestors into feerate), so the specified RBF comment about mining
  code ignoring CPFP is out of date.
