Merge bitcoin/bitcoin#33903: ci: Remove redundant busybox option
fa0fee44a89c82750a39e9d54bb5a6fc72b77fce ci: Remove redundant busybox option (MarcoFalke)
fa102ec69faeffe1be75357447379040e61eb631 doc: Shorten ci name (MarcoFalke)
222222378048b838dd98e41680fc05d70d5f0047 doc: Remove bash -c wrapper (MarcoFalke)

Pull request description:

  The option was fine, but now that there is a dedicated Alpine Linux task, which uses BusyBox, it seems redundant.
  (See: `ci/test/00_setup_env_native_alpine_musl.sh`)

  So remove the `USE_BUSY_BOX` option, along with the `BINS_SCRATCH_DIR` env var.

  Also includes two small ci-doc fixups.

Merge bitcoin/bitcoin#33855: kernel: add btck_block_tree_entry_equals
096924d39d644acc826cbffd39bb34038ecee6cd kernel: add btck_block_tree_entry_equals (stickies-v)

Pull request description:

  `BlockTreeEntry` objects are often compared. This happens frequently in our own codebase and seems likely to be the case for clients, too. Users can already work around this by comparing based on block hash (and optionally height as belt-and-suspenders), but I think this should be part of the interface for performance and consistency reasons.

  Note: perhaps this is too ad-hoc, and we should extend this PR to add the operator for more types? `BlockTreeEntry` is the main one I've needed this for in developing `py-bitcoinkernel`, though.

  `clang-format -i src/test/blockchain_tests.cpp` should recreate the

Merge bitcoin/bitcoin#33893: test: add -alertnotify test for large work invalid chain warning
8343a9ffcc752f77eb2248315d10b6dff4a5c98b test: add `-alertnotify` test for large work invalid chain warning (Sebastian Falbesoner)

Pull request description:

  This PR adds missing test coverage for the `LARGE_WORK_INVALID_CHAIN` fork warning, checked with the `-alertnotify` option:
  ead849c9f1/src/validation.cpp (L2033-L2040)
  Found that this is missing during review of #32587. The test works by first creating a bunch of invalid blocks, that are first announced by headers and then submitted fully in reverse (invalid tip first), in order to set `m_best_invalid` to that value, finally leading to the best chain / invalid chain gap of >= 6 blocks. I'd be curious if there are other (more realistic?) ways to test this. One simple alternative is just to call `invalidateblock` twice (once at the tip, once at the base of the invalid chain).

  Note that the written warning doesn't include the exclamation mark, as it is removed via `SanitizeString` in the `AlertNotify` function.

fa9537cde10120b12c96061cbc3f79a7680f9d64 ci: Use latest Xcode that the minimum macOS version allows (MarcoFalke)

Pull request description:

  Changing the CI policy to use the *latest* Xcode (instead of the *earliest*), allowed by the Bitcoin Core minimum supported macOS version, makes sense: While this may require the developer or user to install a later security point-release on macOS, this should generally be fine and it is even expected that users run the latest supported security release of their operating system. Also, in practise, this often doesn't result in a visible change anyway: This specific change from Xcode 16.0 to 16.2 does not change any behavior of the Bitcoin Core CI, because there are no C++-related changes in those point releases.

Pull request description:

  [Reopening #28676 here as a new PR, because GitHub is slow to load the page making it hard to scroll through and see comments.  Also, that PR was originally opened with a prototype implementation which has changed significantly with the introduction of `TxGraph`.]

  This is an implementation of the [cluster mempool proposal](https://delvingbitcoin.org/t/an-overview-of-the-cluster-mempool-proposal/393).

  This branch implements the following observable behavior changes:

   - Maintains a partitioning of the mempool into connected clusters (via the `txgraph` class), which are limited in vsize to 101 kvB by default, and limited in count to 64 by default.
   - Each cluster is sorted ("linearized") to try to optimize for selecting highest-feerate-subsets of a cluster first
   - Transaction selection for mining is updated to use the cluster linearizations, selecting highest feerate "chunks" first for inclusion in a block template.
   - Mempool eviction is updated to use the cluster linearizations, selecting lowest feerate "chunks" first for removal.
   - The RBF rules are updated to: (a) drop the requirement that no new inputs are introduced; (b) change the feerate requirement to instead check that the feerate diagram of the mempool will strictly improve; (c) replace the direct conflicts limit with a directly-conflicting-clusters limit.
   - The CPFP carveout rule is eliminated (it doesn't make sense in a cluster-limited mempool)
   - The ancestor and descendant limits are no longer enforced.
   - New cluster count/cluster vsize limits are now enforced instead.
   - Transaction relay now uses chunk feerate comparisons to determine the order that newly received transactions are announced to peers.

  Additionally, the cached ancestor and descendant data are dropped from the mempool, along with the multi_index indices that were maintained to sort the mempool by ancestor and descendant feerates. For compatibility (eg with wallet behavior or RPCs exposing this), this information is now calculated dynamically instead.

Previously we would sanity check the -maxmempool configuration based on a

evicted size is now the cluster size limit, so use that instead.

Also allow -maxmempool=0 in general (and not just if

Pull request description:

  Currently, if `-asmap` is specified without a filename bitcoind tries to load `ip_asn.map` data file.

  This change now requires `-asmap=ip_asn.map` or another filename to be specified explicitly.

  The change is intended to make behavior of the option explicit and avoid confusion reported https://github.com/bitcoin/bitcoin/issues/33386 where documentation specifies a default file which is not actually loaded by default. It was originally implemented in
  https://github.com/bitcoin/bitcoin/pull/33631#issuecomment-3410302383 and various alternatives are discussed there.

2a46e94a1600a4f28e01db23a89f039acaa2c45e doc: Update multisig-tutorial.md to use multipath descriptors (Ben Westgate)

Pull request description:

  ### Summary

  Update `doc/multisig-tutorial.md` to use multipath descriptor format
  instead of separate external/internal descriptors. The tutorial now:

  - extracts a single `xpub_n` per participant
  - constructs a multipath `wsh(sortedmulti(...))` descriptor with `<0;1>`
    change index semantics
  - uses `getdescriptorinfo` to compute descriptor checksum
  - explains that `importdescriptors` expands the multipath descriptor
    into internal and external descriptors
  - update `/test/functional/wallet_multisig_descriptor_psbt.py` functional test / documentation to use multi-path descriptors

  ---

  ### Motivation

  A single multipath descriptor is the most convenient pattern for multisig; our documentation should use it.

  ---

  ### What changed

  - replaced extraction of `external_xpub_n` and `internal_xpub_n` with
    extraction of a single `xpub_n`
  - removed instructions to create and import separate external/internal
    descriptors
  - added instructions to build a multipath `wsh(sortedmulti(...))`
    descriptor and derive checksum with `getdescriptorinfo`
  - checksum field is parsed and appended as the multipath descriptor is not the canonical "desc" output
  - clarified that `importdescriptors` automatically expands multipath
    descriptors into internal and external forms
  - similar changes to the functional test: wallet_multisig_descriptor_psbt.

  ---

  ### Testing

  I have run the updated shell snippets and confirmed the multipath descriptor produces the same `listdescriptors` output after importing as the two descriptor method in bitcoin:master.

  ---

  ### Related issues / PRs

  This tutorial change references the multipath descriptor
  consolidation (see commit / PR referenced in the change). The commit
  message points to bitcoin#22838 as the upstream change that enables
  this behavior.

  ---

  ### Release note (for changelog)

  Documentation: update multisig tutorial and multisig functional test to use multipath descriptors

fad0c76d0a109ab7b063f0d405588cf1e6c15e4d clang-format: Set PackConstructorInitializers: CurrentLine (MarcoFalke)

Pull request description:

  Now that the minimum supported clang version is larger than 14, the `PackConstructorInitializers` setting can be set to `CurrentLine` in the clang-format file. (This option was added in clang 14. Ref: https://releases.llvm.org/17.0.1/tools/clang/docs/ClangFormatStyleOptions.html#packconstructorinitializers)

  The `CurrentLine` option will either put all constructor initializers on the current line if they fit. Otherwise, it will put each one on its own line.

  The `CurrentLine` option is desirable over the current `BinPack` option, because:

  * It is what the majority of the codebase is currently using.
  * It makes it easier to skim the lines to ensure all fields are properly initialized, without having to parse bin-packed constructor initializers, possibly with nested initializer lists, function calls, or ternary operators.
  * It makes diffs smaller when an initializer is added or removed, because only a single line is touched. Otherwise, the whole bin-packed block could re-flow, making the diff harder to parse.

  Note: The previous `BinPack` option allows any formatting, due to the current `ColumnLimit: 0`. I presume developers manually formatted most constructor initializers to be on separate lines? With the new `CurrentLine` setting, one has to only put the first initializer on a separate line, and clang-format will take care of the rest.

  For example:

  ```sh
  echo 'A::A(O o)
  : m_first{o.a, o.b},
    m_second{fun(o)}, m_third{o.c?o.d:o.e} {}' | clang-format --style=file:./src/.clang-format
  ```

  Will put each on a separate line. Previously, it was left as-is.

  > You can use the attribute by adding a `LIFETIMEBOUND`

  While grepping, I found an incorrect usage of the `LIFETIMEBOUND` annotation on `BlockManager::CheckBlockDataAvailability`. This could be misleading about usage for other greppers. As I was looking, I also noticed a missing `LIFETIMEBOUND` on `BlockManager::GetFirstBlock`. While looking more closely at that method, it should return a reference instead of a pointer. The only reason to return a pointer is if it can be null.

Merge bitcoin/bitcoin#33905: ci: Consistenly only cache on the default branch
fa411f938e4796cf3806f234c9787b7c79492cc2 ci: Consistenly only cache on the default branch (MarcoFalke)

Pull request description:

  Fixes https://github.com/bitcoin/bitcoin/issues/33685

  The general idea for caches is to only save them on pushes to the default branch, because the cache is limited in size and time that the only benefit of the cache can be to speed up pull requests against the default branch.

  Backport pull requests to older branches don't benefit from caches, because usually they will be running into a cache miss anyway. Also, they would cause the cache size to overflow and lead to cache misses down the line.

  So fix it by consistently applying cache saves only on the default branch.

  For reference, the same is already done for the composite action in this repo: 2444488f6a/.github/actions/save-caches/action.yml (L15)

Pull request description:

  Most of the CI tasks have a long list of stuff that they enable. This makes it hard to see what each CI task is actually running.

  Also, most of the CI tasks should probably mimic the `dev-mode` CMake preset and run on as much stuff as possible. Usually, changing the `dev-mode` comes with changing those CI tasks as well in the same commit, which is verbose.

  Fix both issues, by basing most CI tasks on the `dev-mode`. In the future, this makes it easier to change the `dev-mode` in a single place. If CI tasks explicitly disable something, it will be listed explicitly in them.

  As a side-effect this will enable the kernel stuff for some CI task that did not have it enabled, which seems desirable.
