Pull request description:

  - Document `-color` as only applying to `-getinfo`, to be less confusing for bitcoin-cli users.
  - No longer print version information when getting passed `-noversion`.
  - Disallow `-nodatadir` as we cannot run without one. It was previously interpreted as a mix of unset and as a relative path of "0".
  - Support `-norpccookiefile`
  - Support `-nopid`
  - Properly support `-noconf` (instead of working by accident). Also detect when directories are specified instead of files.

  Prompted by investigation in https://github.com/bitcoin/bitcoin/pull/16545#pullrequestreview-2316714013.

36dbebafb9b54764005e6fffa7ad28d4cadfe5e4 rpc: Remove submitblock coinbase pre-check (TheCharlatan)

Pull request description:

  With the introduction of a mining ipc interface and the potential future introduction of a kernel library API it becomes increasingly important to offer common behaviour between them. An example of this is ProcessNewBlock, which is used by ipc, rpc, net_processing and (potentially) the kernel library. Having divergent behaviour on suggested pre-checks and checks for these functions is confusing to both developers and users and is a maintenance burden.

  The rpc interface for ProcessNewBlock (submitblock) currently pre-checks if the block has a coinbase transaction and whether it has been processed before. While the current example binary for how to use the kernel library, bitcoin-chainstate, imitates these checks, the other interfaces do not.

  The coinbase check is repeated again early during ProcessNewBlock. Pre-checking it may also shadow more fundamental problems with a block. In most cases the block header is checked first, before validating the transactions. Checking the coinbase first therefore masks potential issues with the header. Fix this by removing the pre-check.

  Similary the duplicate checks are repeated early in the contextual checks of ProcessNewBlock. If duplicate blocks are detected much of their validation is skipped. Depending on the constitution of the block, validating the merkle root of the block is part of the more intensive workload when validating a block. This could be an argument for moving the pre-checks into block processing. In net_processing this would have a smaller effect however, since the block mutation check, which also validates the merkle root, is done before.

  Testing spamming a node with valid, but duplicate unrequested blocks seems to exhaust a CPU thread, but does not seem to significantly impact keeping up with the tip. The benefits of adding these checks to net_processing are questionable, especially since there are other ways to trigger the more CPU-intensive checks without submitting a duplicate block. Since these DOS concerns apply even less to the RPC interface, which does not have banning mechanics built in, remove them too.

  Finally, also remove the pre-checks from `bitcoin-chainstate.cpp`.

Pull request description:

  The RPC command `scanblocks` provides a useful way to get a set of blockhashes that have activity relevant to a set of descriptors (`relevant_blocks`). However actually extracting the activity from those blocks is left as an exercise to the end user.

  This process involves not only generating the (potentially ranged) set of scripts for the descriptor set on the client side (maybe via `deriveaddresses`), but then the user must retrieve each block's contents one-by-one using `getblock <hash>`, which is transmitted over a network link. And that's all before they perform the actual search over block content. There's even more work required to incorporate unconfirmed transactions.

  This PR introduces an RPC `getdescriptoractivity` that [dovetails](https://bitcoin-irc.chaincode.com/bitcoin-core-dev/2024-08-16#1046393;) with `scanblocks` output, handling the process described above. Users specify the blockhashes (perhaps from `relevant_blocks`) and a set of descriptors; they are then given all spend/receive activity in that set of blocks.

  This is a very useful tool when implementing lightweight wallets that want neither to require a third-party indexer like electrs, nor the overhead of creating and managing watch-only wallets in Core. This allows Core to be more easily used in a "stateless" manner by wallets, with potentially many nodes interchangeably acting as backends.

  PR inspired by https://github.com/bitcoin/bitcoin/pull/29608#issuecomment-2437847307 (and https://github.com/bitcoin/bitcoin/pull/29458, https://github.com/bitcoin/bitcoin/pull/29606, https://github.com/bitcoin/bitcoin/pull/29607, https://github.com/bitcoin/bitcoin/pull/30093).

  The `clang-tidy` check can be run via:

  run-clang-tidy -quiet -p build -j $(nproc) -checks='-*,performance-inefficient-vector-operation' | grep -v 'clang-tidy'
  ```
  which revealed 3 tests and 1 prod warning (+ fuzz and benching, found by hebasto).
  Even though the tests aren't performance critical, getting rid of these warnings (for which the checks were already enabled via https://github.com/bitcoin/bitcoin/blob/master/src/.clang-tidy#L18, see below), the fix was quite simple.

rpc: Remove submitblock duplicate pre-check
The duplicate checks are repeated early in the contextual checks of
ProcessNewBlock. If duplicate blocks are detected much of their
validation is skipped. Depending on the constitution of the block,
validating the merkle root of the block is part of the more intensive
workload when validating a block. This could be an argument for moving
the pre-checks into block processing. In net_processing this would have
a smaller effect however, since the block mutation check, which also
validates the merkle root, is done before.

A side effect of this change is that a duplicate block is persisted
again on disk even when pruning is activated. This is similar to the
behaviour with getblockfrompeer. Add a release note for this change in
behaviour.

Testing spamming a node with valid, but duplicate unrequested blocks
seems to exhaust a CPU thread, but does not seem to significantly impact
keeping up with the tip. The benefits of adding these checks to
net_processing are questionable, especially since there are other ways
to trigger the more CPU-intensive checks without submitting a duplicate
block. Since these DOS concerns apply even less to the RPC interface,
which does not have banning mechanics built in, remove them too.

---

With the introduction of a mining ipc interface and the potential future
introduction of a kernel library API it becomes increasingly important
to offer common behaviour between them. An example of this is
ProcessNewBlock, which is used by ipc, rpc, net_processing and
(potentially) the kernel library. Having divergent behaviour on
suggested pre-checks and checks for these functions is confusing to both
developers and users and is a maintenance burden.

The rpc interface for ProcessNewBlock (submitblock) currently pre-checks
if the block has a coinbase transaction and whether it has been
processed before. While the current example binary for how to use the
kernel library, bitcoin-chainstate, imitates these checks, the other
interfaces do not.

rpc: Remove submitblock invalid-duplicate precheck
ProcessNewBlock fails if an invalid duplicate block is passed in through
its call to AcceptBlock and AcceptBlockHeader. The failure in
AcceptBlockHeader makes AcceptBlock return early. This makes the
pre-check in submitblock redundant.

rpc: Remove submitblock coinbase pre-check
The coinbase check is repeated again early during ProcessNewBlock.
Pre-checking it may also shadow more fundamental problems with a block.
In most cases the block header is checked first, before validating the
transactions. Checking the coinbase first therefore masks potential
issues with the header. Fix this by removing the pre-check.

The pre-check was likely introduced on top of
ada0caa165905b50db351a56ec124518c922085a to fix UB in
GetWitnessCommitmentIndex in case a block's transactions are empty. This
code path could only be reached because of the call to
UpdateUncommittedBlockStructures in submitblock, but cannot be reached
through net_processing.

Add some functional test cases to cover the previous conditions that
lead to a "Block does not start with a coinbase" json rpc error being
returned.

a51e91783aac0beefcb604be159eb1cb96a39051 validation: add RecalculateBestHeader() function (Martin Zumsande)

Pull request description:

  `m_best_header` (the most-work header not known to be on an invalid chain) can be wrong in the context of invalidation / reconsideration of blocks. This can happen naturally (a valid header is received and stored in our block tree db; when the full block arrives, it is found to be invalid) or triggered by the user with the `invalidateblock` / `reconsiderblock` rpc.

  We don't currently use `m_best_header` for any critical things (see OP of #16974 for a list that still seems up-to-date), so it being wrong affects mostly rpcs.

  This PR proposes to recalculate it if necessary by looping over the block index and finding the best header. It also suggest to mark headers between an invalidatetd block and the previous `m_best_header` as invalid, so they won't be considered in the recalculation.
  It adds tests to `rpc_invalidateblock.py` and `rpc_getchaintips.py` that fail on master.

  One alternative to this suggested in the past would be to introduce a continuous tracking of header tips (#12138).
  While this might be more performant, it is also more complicated, and situations where we need this data are only be remotely triggerable by paying the cost of creating a valid PoW header for an invalid block.
  Therefore I think it isn't necessary to optimise for performance here, plus the solution in this PR doesn't perform any extra steps in the normal node operation where no invalidated blocks are encountered.

  Fixes  #26245

Pull request description:

  The confusing "command" terminology for the 12-byte field in the (v1) p2p message header was replaced with the more proper term "message type" in other modules already years ago, see eg #18533, #18937, #24078, #24141. This PR does the same for the protocol.{h,cpp} module to complete the replacements. Note that "GetCommand" is a method name also used in the `ArgsManager` (there it makes much more sense), so the scripted-diff lists for this replacement the files explicitly, rather than using `$(git grep -l ...)`.

  Given https://github.com/bitcoin/bitcoin/pull/30493 and the related discussion on network uptake it's probably not helpful to have an option for a feature that will not be respected by the network in any meaningful way.

  Wallet changes can be done in another PR on its own cadence to account for possible fingerprinting, waiting for fullrbf logic to permeate the network, etc.

  Implements follow-up suggestions from #30793.

  - Now disallows undefined verbosity levels (below and above valid values) (https://github.com/bitcoin/bitcoin/pull/30793#discussion_r1786093549)
  - Disallows boolean verbosity (https://github.com/bitcoin/bitcoin/pull/30793#discussion_r1788273274) and adds guidance to developer-notes
  - Checks that `getorphantxs` is a hidden rpc (https://github.com/bitcoin/bitcoin/pull/30793#discussion_r1786107786)
  - Adds a test for `expiration` time
  - Adds `entry` time to the returned orphan objects (verbosity >=1) to relieve the user from having to calculate it from `expiration`.  Also adds associated test. (https://github.com/bitcoin/bitcoin/pull/30793#discussion_r1743687732)
  - Minor cleanup (blank line removal and log message move) (https://github.com/bitcoin/bitcoin/pull/30793#discussion_r1786092641)

  Included a commit to rename the test to a more generic `get_orphans` to better accommodate future orphanage-related RPCs (e.g. `getorphanangeinfo`).  Can drop the refactor commit from this PR if people feel strongly about it.

e31bfb26c21f8b72f8c317e016d375862e27502e refactor: Remove unrealistic simulation state (Lőrinc)

Pull request description:

  While reviewing [the removal of the unreachable combinations from the Coin cache logic](https://github.com/bitcoin/bitcoin/pull/30673#discussion_r1721727681), we've noticed that the related tests often [reflect impossible states](https://github.com/bitcoin/bitcoin/pull/30673/files#r1740154464).

  Browsing the Coin cache refactoring history revealed that migrating `bool GetCoin` to `optional<Coin> GetCoin` was [already proposed a few times before](https://github.com/bitcoin/bitcoin/pull/18746#issuecomment-842393167).

  This refactor makes certain invalid states impossible, reducing the possibility of errors and making the code easier to understand. This will let us remove test code that exercises the impossible states as well.
  The PR is done in multiple small steps, first swapping the new `optional` return value, slowly strangling out the usages of the return parameter, followed by the removal of the parameter.

  Most of the invalid test states were still kept, except for https://github.com/bitcoin/bitcoin/pull/30673/files#r1748087322, where the new design prohibits invalid usage and https://github.com/bitcoin/bitcoin/pull/30673/files#r1749350258 was just marked with a TODO, will be removed in a follow-up PR.

  - Improve documentation of `mapped_as`/`source_mapped_as` in `getrawaddrman` RPC by mentioning that both fields will be only available if asmap flag is set. It is the same message for `mapped_as` field in `getpeerinfo`.

`{source_}mapped_as` (that are optional in getrawaddrman)
will be only available if the asmap config flag is set.

Pull request description:

  `g_genesis_wait_cv` is similar to `m_tip_block_cv` but shuffling everything through a redundant `boost::signals2`.

  So remove it, along with some other dead code, as well as minor fixups.

5ca28ef28b refactor: Split up NodeContext shutdown_signal and shutdown_request
Instead of having a single NodeContext::shutdown member that is used both to
request shutdowns and check if they have been requested, use separate members
for each. Benefits of this change:

1. Should make code a little clearer and easier to search because it is easier
   to see which parts of code are triggering shutdowns and which parts are just
   checking to see if they were triggered.

2. Makes it possible for init.cpp to specify additional code to run when a
   shutdown is requested, like signalling the m_tip_block_cv condition variable.

Motivation for this change was to remove hacky NodeContext argument and
m_tip_block_cv access from the StopRPC function, so StopRPC can just be
concerned with RPC functionality, not other node functionality.

bugfix: Mark m_tip_block_cv as guarded by m_tip_block_mutex
This is not strictly required, but all places using m_tip_block_cv
(except shutdown) already take the lock. The annotation makes it easier
to catch potential deadlocks before review.

Adding the missing lock to the shutdown sequence is a bugfix.

An alternative would be to take the lock and release it before
notifying, see
