Merge #15323: rpc: Expose g_is_mempool_loaded via getmempoolinfo
effe81f750 Move g_is_mempool_loaded into CTxMemPool::m_is_loaded (Ben Woosley)
bb8ae2c419 rpc: Expose g_is_mempool_loaded via getmempoolinfo and /rest/mempool/info.json (Ben Woosley)

Pull request description:

  And use it to fix a race condition in mempool_persist.py:
  https://travis-ci.org/Empact/bitcoin/jobs/487577243

  Since e.g. getrawmempool returns errors based on this status, this
  enables users to test it for readiness.

  Fixes #12863

Pull request description:

  I'm resurrecting this one (from #13168) because I need it to make progress on #15735.

  It's now off by default and can be turned on with `-logthreadnames=1`.

  Ran some benchmarks (IBD from local peer from 500_000 -> 504_000) and it's within spitting distance either on or off:

ae5f2b6a6c threads: introduce util/threadnames, refactor thread naming
This work is prerequisite to attaching thread names to log lines and deadlock
debug utilities. This code allows setting of an "internal" threadname per
thread on platforms where thread_local is available.

This commit also moves RenameThread() out of a more general module and adds a
numeric suffix to disambiguate between threads with the same name. It
explicitly names a few main threads using the new util::ThreadRename().

Merge #15655: Resolve the checkpoints <-> validation circular dependency
418d3230f8 Resolve the checkpoints <-> validation CD. (251)

Pull request description:

  This pull request attempts to resolve the `checkpoints -> validation -> checkpoints` circular dependency.

  The circular dependency is resolved by moving the `CheckPoints::GetLastCheckpoint(const CCheckpointData& data)` function to `validation.cpp` where it used exclusively by the private function `ContextualCheckBlockHeader(const CBlockHeader& block, CValidationState& state, const CChainParams& params, const CBlockIndex* pindexPrev, int64_t nAdjustedTime)`.

ACKs for commit 418d32:

5c759c73b2 [wallet] Move maxTxFee to wallet
This commit moves the maxtxfee setting to the wallet. There is only
one minor behavior change:

- an error message in feebumper now refers to -maxtxfee instead of
maxTxFee.

fdf8888b6f [build] Move CheckTransaction from lib_server to lib_consensus (John Newbery)

Pull request description:

  This is a move-only commit. No code is changing and the moves can be easily verified with:

  ```sh
  git log -p -n1 --color-moved=dimmed_zebra
  ```

  This commit moves functions and variables that wallet code depends on out of libbitcoin_server.a, so the bitcoin-wallet tool can be built without libbitcoin_server.a in #15639, and attempting to access server state from wallet code will result in link errors instead of silently broken code.

  List of moves:

  - `CheckTransaction` moves from `consensus/tx_verify.cpp` to `consensus/tx_check.cpp`
  - `urlDecode` moves from `httpserver.cpp` to `util/url.cpp`
  - `TransactionErrorString` moves from `node/transaction.cpp` to `util/error.cpp`
  - `StringForFeeReason` and `FeeModeFromString` move from `policy/fees.cpp` to `util/fees.cpp`
  - `incrementalRelayFee` `dustRelayFee` and `nBytesPerSigOp` move from `policy/policy.cpp` to `policy/settings.cpp`
  - `SignalsOptInRBF` moves from `policy/rbf.cpp` to `util/rbf.cpp`
  - `fIsBareMultisigStd` moves from `validation.cpp` to `policy/settings.cpp`
  - `ConstructTransaction` `TxInErrorToJSON` and `SignTransaction` move from `rpc/rawtransaction.cpp` to `rpc/rawtransaction_util.cpp`
  - `RPCTypeCheck` `RPCTypeCheckArgument` `RPCTypeCheckObj` `AmountFromValue` `ParseHashV``ParseHashO` `ParseHexV` `ParseHexO` `HelpExampleCli` and `HelpExampleRpc` move from `rpc/server.cpp` to `rpc/util.cpp`
  - `AmountHighWarn` and `AmountErrMsg` move from `ui_interface.cpp` to `util/error.cpp`
  - `FormatStateMessage` and `strMessageMagic` move from `validation.cpp` to `util/validation.cpp`
  - `VerifyWallets` `LoadWallets` `StartWallets` `FlushWallets` `StopWallets` and `UnloadWallets` move from `wallet/init.cpp` to `wallet/node.cpp`

Pull request description:

  This PR makes a number of improvements to the InvalidateBlock (`invalidateblock` RPC) and RewindBlockIndex functions, primarily around breaking up their long-term cs_main holding. In addition:
  * They're made safely interruptible (`bitcoind` can be shutdown, and no progress in either will be lost, though if incomplete, `invalidateblock` won't continue after restart and will need to be called again)
  * The validation queue is prevented from overflowing (meaning `invalidateblock` on a very old block will not drive bitcoind OOM) (see #14289).
  * `invalidateblock` won't bother to move transactions back into the mempool after 10 blocks (optimization).

  This is not an optimal solution, as we're relying on the scheduler call sites to make sure the scheduler doesn't overflow. Ideally, the scheduler would guarantee this directly, but that needs a few further changes (moving the signal emissions out of cs_main) to prevent deadlocks.

  I have manually tested the `invalidateblock` changes (including interrupting, and running with -checkblockindex and -checkmempool), but haven't tried the rewinding (which is probably becoming increasingly unnecessary, as very few pre-0.13.1 nodes remain that would care to upgrade).

Pull request description:

  This cleans up and refactors block file helpers so that they may be used by the block filter indexer. Per [design discussion](https://github.com/bitcoin/bitcoin/pull/14121#issuecomment-451252591) about storing BIP 157 block filters, it has been suggested that they are stored in the same way as block and undo data. This refactor is sufficient to simplify file operations for this use case, though in the future perhaps more pruning-related logic ought to be moved into the new classes.

  The basic abstraction is a `FlatFileSeq` which manages access to a sequence of numbered files into which raw data is written.

ef362f2773 rpc/gui: Remove 'Unknown block versions being mined' warning
Due to miners inserting garbage into the version numbers, the current
version signalling has become completely useless. This removes the
"unknown block versions" warning which has the tendency to scare
users unnecessarily (and might get them to "update" to something
bad).

It preserves the warning in the logs. Whether this is desirable can
be a point of discussion.

9d6dcc52c6 Abstract EraseBlockData out of RewindBlockIndex
Note that the former 'else' branch in RewindBlockIndex is now
dealt with more naturally inside the EraseBlockData call (by
checking whether the parent needs to be re-added as candidate
after deleting a child).

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.
