This makes TxGraph also use the fallback order to decide the order of
chunks from distinct clusters.
The order of chunks across clusters becomes:
1. Feerate (high to low)
2. Equal-feerate-chunk-prefix (small to large)
3. Max-txid (chunk with lowest maximum-txid first)
This makes the full TxGraph ordering fully deterministic as long as all
clusters in it are optimally linearized.
Add glue to make TxGraph use the fallback order provided to it, in the
fallback comparator it provides to the cluster linearization code.
The order of chunks within a cluster becomes:
1. Topology (chunks after their dependencies)
2. Feerate (high to low)
3. Weight (small to large)
4. Max-txid (chunk with lowest maximum-txid first)
The order of transactions within a chunk becomes:
1. Topology (parents before children)
2. Individual transaction feerate (high to low)
3. Weight (small to large)
4. Txid (low to high txid)
This makes optimal cluster linearization, both the order of chunks
within a chunk, and the order of transactions within those chunks,
completely deterministic.
This adds an std::function<strong_ordering(Ref&,Ref&)> argument to the
MakeTxGraph function, which can be used by the caller (e.g., mempool
code) to provide a fallback order to TxGraph.
This is just preparation; TxGraph does not yet use this fallback order
for anything.
This is a small change to the txgraph fuzz test to make it used objects
derived from TxGraph::Ref (SimTxObject) rather than TxGraph::Ref
directly. This matches how the mempool uses CTxMemPoolEntry, which
derives from TxGraph::Ref.
This is preparation for a future commit which will introduce simulated
txids to the transactions in this fuzz test, to be used as fallback
order.
This allows passing in a fallback order comparator to Linearize(), which
is used as final tiebreak when deciding the order of chunks and
transactions within a chunk, rather than a random tiebreak.
The order of transactions within a chunk becomes:
1. Topology (parents before children)
2. Individual transaction feerate (high to low)
3. Weight (small to large)
4. Fallback (low to high fallback order)
The order of chunks within a cluster becomes:
1. Topology (chunks after their dependencies)
2. Feerate (high to low)
3. Weight (small to large)
4. Max-fallback (chunk with lowest maximum-fallback-tx first)
For now, txgraph passes a naive comparator to Linearize(), which makes
the cluster order deterministic when treating the input transactions as
identified by the DepGraphIndex. However, since DepGraphIndexes are the
result of possibly-randomized operations inside txgraph, this doesn't
actually make txgraph's per-cluster ordering deterministic. That will be
changed in a later commit, by using a txid-based fallback instead.
This makes TxGraph track the equal-feerate-prefix size of all chunks in
all clusters in the main graph, and uses it to sort chunks coming from
distinct clusters.
The order of chunks across clusters becomes:
1. Feerate (high to low)
2. Equal-feerate-prefix (small to large)
3. Cluster sequence number (old to new); this will be changed later.
The equal-feerate-prefix size of a chunk C is defined as the sum
of the weights of all chunks in the same cluster as C, with the same
feerate as C, up to and including C itself, in linearization order (but
excluding such chunks that appear after C).
This is an approximation of sorting chunks from small to large across
clusters, while remaining consistent with intra-cluster linearization
order.
This changes the order of transactions within a chunk to be:
1. Topology (parents before children)
2. Individual transaction feerate (high to low)
3. Individual transaction weight (small to large)
4. Random tiebreak (will be changed in a future commit)
To do so, use a heap of topology-ready transactions within
GetLinearization(), sorted by (2), (3), and (4).
This is analogous to the order of chunks within a cluster, which is
unchanged:
1. Topology (chunks after chunks they depend on)
2. Chunk feerate (high to low)
3. Chunk weight (small to large)
4. Random tiebreak (will be changed in a future commit)
Whenever a TxGraph::Ref is destroyed, if it by then still appears inside
main-level clusters, wipe the chunk index entries for those clusters, to
prevent having lingering indexes for transactions without Ref.
This is preparation for enabling a callback being passed to MakeTxGraph
to define a fallback order on objects. Once the Ref for a transaction is
gone, it is not possible to invoke the callback anymore. To prevent the
index becoming inconsistent, we need to immediately get rid of the index
entries when the Ref disappears.
This is not a problem, because such destructions necessarily will
trigger a relinearization of the cluster (assuming there are
transactions in it left) before becoming acceptable again, and the chunk
ordering is not observable (through CompareMainOrder, or through the
BlockBuilder interface) until that point. However, the index itself
needs to remain consistent in the mean time, even if not meaningful.
This makes TxGraphImpl::Compact() invoke Cluster::Updated() on all
affected clusters, in case they have internal GraphIndex values stored
that may have become outdated with the renumbering of GraphIndex values
that Compact() caused.
No such GraphIndex values are currently stored, but this will change in
a future commit.
Instead of returning a TxGraph::Ref from TxGraph::AddTransaction(),
pass in a TxGraph::Ref& which is updated to refer to the new transaction
in that graph.
This cleans up the usage somewhat, avoiding the need for dummy Refs in
CTxMemPoolEntry constructor calls, but the motivation is that a future
commit will allow a callback to passed to MakeTxGraph to define a
fallback order on the transaction objects. This does not work when a
Ref is created separately from the CTxMemPoolEntry it ends up living in,
as passing the newly-created Ref to the callback would be UB before it's
emplaced in its final CTxMemPoolEntry.

fa6801366d refactor: [rpc] Remove confusing and brittle integral casts (take 2) (MarcoFalke)
Pull request description:
Second take for cases which I seem to have missed in commit 94ddc2dced.
When constructing an UniValue from integral values, historically (long ago), in some cases casts where needed. With the current UniValue constructor, only very few are actually needed.
Keeping the unused casts around is:
* confusing, because code readers do not understand why they are needed
* brittle, because some may copy them into new places, where they will lead to hard-to-find logic bugs, such as the ones fixed in pull https://github.com/bitcoin/bitcoin/pull/34112
So fix all issues by removing them, except for a few cases, where casting was required:
* `static_cast<bool>(fCoinBase)`, because `bool{fCoinBase}` only works on modern compilers.
This hardening refactor does not fix any bugs and does not change any behavior.

88d9092571 cmake: Create subdirectories in build tree in advance (Hennadii Stepanov)
Pull request description:
While reviewing https://github.com/bitcoin/bitcoin/pull/32697, I noticed that symlink creation fails when the target subdirectory does not exist. In such cases, `file(CREATE_LINK ... COPY_ON_ERROR SYMBOLIC)` falls back to copying, which implicitly creates the required path. As a result, a single file is copied instead of symlinked for subdirectories in `test/functional`.
This PR ensures that necessary subdirectories are created in advance, so that subsequent symlink creation does not fail due to missing paths.

7378f27b4f test: run utxo-to-sqlite script test with spk/txid format option combinations (Sebastian Falbesoner)
b30fca7498 contrib: utxo_to_sqlite.py: add options to store txid/spk as BLOBs (Sebastian Falbesoner)
Pull request description:
This PR is a late follow-up to https://github.com/bitcoin/bitcoin/pull/27432, introducing an option for the utxo-to-sqlite script to store the txid/scriptPubKey columns as bytes (= `BLOB` storage class in sqlite, see e.g. https://www.sqlite.org/datatype3.html in sqlite) rather than hex strings. This was proposed in earlier reviews (https://github.com/bitcoin/bitcoin/pull/27432#issuecomment-1516857024, https://github.com/bitcoin/bitcoin/pull/27432#issuecomment-1653739351) and has the obvious advantage of a significantly smaller size of the resulting database (and with that, faster conversion) and the avoidance of hex-to-bytes conversion for further processing of the data [1]. The rationale on why hex strings were chosen back then (and still stays the default, if only for compatibility reasons) is laid out in https://github.com/bitcoin/bitcoin/pull/27432#issuecomment-1516922824 [2].
The approach taken is introducing new parameters `--spk` and `--txid` which can either have the values "hex", "raw" (for scriptpubkey) and "hex", "raw", "rawle" (for txid). Thanks to ajtowns for providing this suggestion. Happy to take further inputs on naming and thoughts on future extensibility etc.
[1] For a concrete example, I found that having these columns as bytes would be nice while working on a SwiftSync hints generator tool (https://github.com/theStack/swiftsync-hints-gen), which takes the result of the utxo-to-sqlite tool as input.
[2] note that in contrast what I wrote back then, I think there is no ambiguity on byte-string-serialization of txids; they are ultimately just hash results and hence, they should be stored as such, and adding a big/little endian knob wouldn't make much sense. The drawback of not being able to immediately show txid-strings (as one would need to do the bytes-reversal step first, which is not possible in sqlite, see e.g. https://github.com/bitcoin/bitcoin/pull/24952#issuecomment-1165499803) still remains though.

Pull request description:
This is a mostly move-only change. It's a small refactoring that allows logging macros to be used by including a simple `util/log.h` header instead of the full `logging.h` logging implementation. Most of the changes here were cherry-picked from #34374.
Original motivation for this change was to reduce the size and complexity of #34374 (kernel structured logging PR) and reduce the number of conflicts it causes with other PRs. But this should also make sense as a standalone change to have a clearer separation of concerns between log generation and log handling, and avoid needing to depend on the whole logging framework in call sites that only emit log messages.

b73a62f667 test: Ensure invalid block was processed before checking debug.log (Ava Chow)
Pull request description:
Prior to merging a PR, I run 4 different build configurations and their tests in parallel, and consistently one of those will have `feature_assumevalid.py` fail. The failure is because the `assert_debug_log` context exits before the invalid block is processed, so the lines it is looking for don't appear in the part of the log that it is examining.
This PR should resolve that issue by waiting for `getchaintips` to report that the invalid chain is invalid before exiting the `assert_debug_log` context.

Pull request description:
There is a single unit test, which calls the internal `ProcessMessage` function. This is problematic, because it makes future changes harder, since they will need to carry over this public internal interface each time.
Also, there is a mixed use of pointers and references in p2p code, where just based on context, a pointer may sometimes assumed to be null, or non-null. This is confusing when reading the code, or making or reading future changes.
Fix both issues in a series of commits, to:
* refactor the single unit test to call higher-level functions
* Make `ProcessMessage` private again
* Use references instead of implicit non-null pointers, mostly in a scripted-diff

2. 2202ab5975: ensure `set<shared_ptr<COutput>>` has unique COutput
3. a5ffbbf122: Correctly reserve size when flattening `CoinsResult.coins` map to vector
3. the next 3 commits from 4745d5480c replace the `PreSelectedInputs` struct with `CoinsResult` and removes `PreSelectedInputs`.
4. the last commit (e664484a6d) deals with the error message - `AmountWithFeeExceedsBalance` error inside `WalletModel::prepareTransaction` is never thrown and remains an unused code path. This is because `createTransaction` does not retrieve the fee when the process fails. The fee return arg is set only at the end of the process, when the transaction is successfully created. Therefore, if the transaction creation fails, the fee is not available inside `WalletModel::prepareTransaction` to trigger the `AmountWithFeeExceedsBalance` error.
This PR re-implements the feature inside `CreateTransactionInternal` and adds test coverage for it.

In feature_assumevalid.py, we check that a modified block 102 is invalid
by asserting a message in the debug.log. However, this can
intermittently fail as exiting the assert_debug_log can occur before the
block has actually been validated, thus causing the test to fail as the
validation error message is not present in the chunk of the debug.log
being examined.
We can wait for the block to make an invalid chain tip to ensure that the log
line will be present.
Split the Mining interface test into focused subtests.
Keep the initial tip-change pre-mine check in run_mining_interface_test.
As a result run_block_template_test no longer has newblockref.
Split Mining interface tests into interface_ipc_mining.py and keep
interface_ipc.py for echo + simple inspectors.
Register the new test in test_runner.py.
The setup code around "Create Mining proxy object" is duplicated
in the new test file, but the simple insector checks below it
are not moved.
d79249d279 ci: add chimera Linux LTO CI job (fanquake)
Pull request description:
Adds a CI config based on using [Chimera Linux](https://chimera-linux.org/). This might be interesting for any of the following:
* Chimera is based on LLVM & musl libc - we test both of these in isolation, but not together.
* No GNU components. I don't think we have an existing Linux CI job that doesn't have a gcc/stdlibc++ install. This exercises the depends logic for a fully LLVM/Clang/lld only build, including building the native tools (related to #33902).
* We don't currently have a job with LTO enabled (here using CMakes `CMAKE_INTERPROCEDURAL_OPTIMIZATION`, which is `-flto=thin` for LLVM/Clang). I think this is worth having generally (we do use LTO in some other places, like oss-fuzz). If runtime is too much of an issue, then it could also be dropped. (Chimera itself is also compiled with LTO).
QT in depends doesn't build (#32744), so is excluded for now.
Chimera has pointed out at least a few quirks, i.e #34390, #34408 and https://github.com/bitcoin/bitcoin/pull/29963#discussion_r2707922298.

b65a3d8009 iwyu: Fix patch to prefer `<cstdint>` (Hennadii Stepanov)
Pull request description:
The goal of the [patch](https://github.com/bitcoin/bitcoin/blob/master/ci/test/01_iwyu.patch) is to suggest C++ headers rather than their C counterparts. However, for fixed width integer types, the patched IWYU currently suggests `<cinttypes>` where `<cstdint>` is sufficient.
This PR fixes this behavior.

PreSelectedInputs is confusing to use. it's `total_amount`
might store total amount or effective amount based on SFFO.
ex: we might accidentally sum preselected inputs effective
amount (named `total_amount`) with automatically selected
inputs actual total amount.
CoinsResult has a cleaner interface with separate fields
for both these amounts.
2 behavioural changes:
1. no more default assert error if effective value is unset
- previously PreSelectedInputs::Insert() called
COutput::GetEffectiveValue() which assert failed
if the optional was unset.
- now we don't default assert anymore.
* in GUI/getAvailableBalance better not to assert.
* SelectCoins's preselected inputs always contain a
feerate, so effective amount should be set.
explicitly added an assertion to ensure this.
2. FetchSelectedInputs uses OutputType::UNKNOWN as key to
populate CoinsResult's coins map. it's discarded later.
faa4ab113c ci: Drop valgrind fuzz from GHA matrix (MarcoFalke)
Pull request description:
The valgrind fuzz task is problematic, because:
* It is redundant with the msan fuzz task, which has std lib hardening enabled, so often UB is diagnosed before it even happens in the valgrind task.
* All issues so far found by the valgrind fuzz task were also found by the hardened msan fuzz task.
* All other issues were false-positives, which are hard to debug, and confusing and tedious to work around.
I don't think there is any value in asking pull request authors to debug valgrind false-positives that they triggered by accident. So remove the task for now.
I know that there are some devs, who like to keep the task, but if the task is kept, it should come with clear instructions on how to deal with false-postives in pull requests.
I am not proposing to remove the config itself, and I am happy to continue maintaining it, like it was done before. However, as of now, running it in the GHA matrix is of negative or questionable benefit.

ACK faa4ab113c - hopefully we can revisit re-adding soon. To be clear, I don't agree with the rationale from #34304, or the initial changes there. The case here, and the fact that it is causing disruption in this repo, is more pressing.
