facb152697 scripted-diff: Bump copyright headers after include changes
Historically, the headers have been bumped some time after a file has
been touched. Do it now to avoid having to touch them again in the
future for that reason.

fae71d30f7 clang-tidy: Apply modernize-deprecated-headers
This can be reproduced according to the developer notes with something
like

( cd ./src/ && ../contrib/devtools/run-clang-tidy.py -p ../bld-cmake -fix -j $(nproc) )

Also, the header related changes were done manually.

Pull request description:

  Some users really seem to care about this. While it shouldn't matter much, the diff is so trivial that it is probably worth doing.

  Fixes #31127

  One could also consider to split the field into two dedicated ones (https://github.com/bitcoin/bitcoin/issues/28847#issuecomment-1807115357), but this is left for a more involved follow-up and may also be controversial.

Pull request description:

  Eliminate one block header hash calculation per block-read by reusing the hash for:
  * proof‑of‑work verification;
  * (optional) integrity check against the supplied hash.

  This part of the code wasn't covered by tests either, so the first commit exercises this part first, before pushing the validation to the delegate method.

It is cheap to calculate and the caller does not have to take a lock to
calculate it.

Also turn pointers that can never be null into references.

Pull request description:

  Currently, we do not add the sighash field to PSBTs at all, even when we have signed with a non-default sighash. This PR changes the behavior such that when we (attempt to) sign with a sighash other than DEFAULT or ALL, the sighash type field will be added to the PSBT to inform the later signers that a different sighash type was used by a signer. Notably, this is necessary for MuSig2 support as all signers must sign using the same sighash type, but the sighash is not provided in partial signatures.

  Furthermore, because the sighash type can also be provided on the command line, we require that if both a command line sighash type and the sighash field is present, they must specify the same sighash type. However, this was being checked by the wallet, rather than the signing code, so the `descriptorprocesspsbt` RPC was not enforcing this restriction at all, and in fact ignored the sighash field entirely. This PR refactors the checking code so that the underlying PSBT signing function `SignPSBTInput` does the check.

e58b680923 psbt: Return PSBTError from SignPSBTInput
SignPSBTInput will need to report the specific things that caused an
error to callers, so change it to return a PSBTError. Additionally some
callers will now check the return value and report an error to the user.

Currently, this should not change any behavior as the things that
SignPBSTInput will error on are all first checked by its callers.

Pull request description:

  #### Motivation

  In  [Internal interface guidelines](https://github.com/bitcoin/bitcoin/blob/master/doc/developer-notes.md#internal-interface-guidelines)

  It's stated that

  > Interface method definitions should wrap existing functionality instead of implementing new functionality. Any substantial new node or wallet functionality should be implemented in [src/node/](https://github.com/bitcoin/bitcoin/blob/master/src/node) or [src/wallet/](https://github.com/bitcoin/bitcoin/blob/master/src/wallet) and just exposed in [src/interfaces/](https://github.com/bitcoin/bitcoin/blob/master/src/interfaces) instead of being implemented there, so it can be more modular and accessible to unit tests.

  However the some methods in the newly added  `BlockTemplateImpl` and `MinerImpl`  classes partially enforces this guideline, as the implementations of the `submitSolution`, `waitNext`, and `waitTipChanged` methods reside within the class itself.

  #### What the PR Does

  This PR introduces a simple refactor by moving certain method implementations from `BlockTemplateImpl` into the miner module. It introduces three new functions:

  1.  Remove rundundant coinbase fee check in `waitNext`
  2. **`AddMerkleRootAndCoinbase`**: Computes the block's Merkle root, inserts the coinbase transaction, and sets the Merkle root in the block. This function is called by `submitSolution` before the block is submitted for processing.

  3. **`WaitAndCreateNewBlock`**: Returns a new block template either when transaction fees reach a certain threshold or when a new tip is detected. If a timeout is reached, it returns `nullptr`. The `waitNext` method in `BlockTemplateImpl` now simply wraps this function.
  4. Move `GetTip` implementation to miner.

  5. **`WaitTipChanged`**: Returns the tip when the chain it changes, or `nullopt` if a timeout or interrupt occurs. The `waitTipChanged` method in `MinerImpl` now calls `GetTip` after invoking `ChainTipChanged`, and returns the tip.

  #### Behavior Change

  - We now only `Assert` for  a valid chainman and notifications pointer once.

    Code review ACK 62fc42d475. Lots of suggest suggest changes made since last review, altering function names and signatures and also adding new commit to drop negative fee handling. I like the idea of making the wait function return a BlockRef, that is clearer than what I suggested. Left some comments below but they are not important and this looks good as-is

Pull request description:

  The Consensus Cleanup soft fork proposal includes enforcing that coinbase transactions set their
  nLockTime field to the block height minus 1, as well as their nSequence such as to not disable the
  timelock. If such a fork were to be activated by Bitcoin users, miners need to be ready to produce
  compliant blocks at the risk of losing substantial amounts mining would-be invalid blocks. As miners
  are unfamously slow to upgrade, it's good to make this change as early as possible.

  Although Bitcoin Core's GBT implementation does not provide the `coinbasetxn` field, and mining
  pool software crafts the coinbase on its own, updating the Bitcoin Core mining code is a first step
  toward convincing pools to update their (often closed source) code. A possible followup is also to
  introduce new fields to GBT. In addition, this first step also makes it possible to test future
  Consensus Cleanup changes.

  The commit making the change also updates a bunch of seemingly-unrelated tests. This is because those tests were asserting error messages based on the txid of transactions involved, and changing the coinbase transaction structure necessarily changes the txid of all tests' transactions.

524f981bb8 Bugfix: Miner: Don't reuse block_reserved_weight for "block is full enough to give up" weight delta (Luke Dashjr)

Pull request description:

  PR #30356 incorrectly changed a constant of `4000` to `m_options.coinbase_max_additional_weight` in the check for when to give up finding another transaction to fill the block:

  ```diff
               if (nConsecutiveFailed > MAX_CONSECUTIVE_FAILURES && nBlockWeight >
  -                    m_options.nBlockMaxWeight - 4000) {
  +                    m_options.nBlockMaxWeight - m_options.block_reserved_weight) {

                   break;
               }
  ```

  But this constant did not deal with the reserved weight at all. It was in fact simply checking if the block was close to full, and if so, giving up finding another transaction to pad it with after `MAX_CONSECUTIVE_FAILURES` failed attempts.

  It doesn't seem very logical to reuse the reserve weight for this purpose, and it would be overcomplicated to add yet another setting, so this PR changes it to a new constexpr.

8f2078af6a miner: timelock coinbase transactions
The Consensus Cleanup soft fork proposal includes enforcing that coinbase transactions set their
locktime field to the block height, minus 1 (as well as their nSequence such as to not disable the
timelock). If such a fork were to be activated by Bitcoin users, miners need to be ready to produce
compliant blocks at the risk of losing substantial amounts mining would-be invalid blocks. As miners
are unfamously slow to upgrade, it's good to make this change as early as possible.

Although Bitcoin Core's GBT implementation does not provide the "coinbasetxn" field, and mining

toward convincing pools to update their (often closed source) code. A possible followup is also to
introduce new fields to GBT. In addition, this first step also makes it possible to test future
Consensus Cleanup changes.

The changes to the seemingly-unrelated RBF tests is because these tests assert an error message
which may vary depending on the txid of the transactions used in the test. This commit changes the
coinbase transaction structure and therefore impact the txid of transactions in all tests.

The change to the "Bad snapshot" error message in the assumeutxo functional test is because this
specific test case reads into the txid of the next transaction in the snapshot and asserts the error
message based it gets on deserializing this txid as a coin for the previous transaction. As this
commit changes this txid it impacts the deserialization error raised.

Pull request description:

  This change is part of [[IBD] - Tracking PR for speeding up Initial Block Download](https://github.com/bitcoin/bitcoin/pull/32043)

  ### Summary
  We can serialize the blocks and undos to any `Stream` which implements the appropriate read/write methods.
  `AutoFile` is one of these, writing the results "directly" to disk (through the OS file cache). Batching these in memory first and reading/writing these to disk is measurably faster (likely because of fewer native fread calls or less locking, as [observed](https://github.com/bitcoin/bitcoin/pull/28226#issuecomment-1666842501) by Martinus in a similar change).

  ### Unlocking new optimization opportunities

  Buffered writes will also enable batched obfuscation calculations (implemented in https://github.com/bitcoin/bitcoin/pull/31144) - especially since currently we need to copy the write input's std::span to do the obfuscation on it, and batching enables doing the operations on the internal buffer directly.

  ### Measurements (micro benchmarks, full IBDs and reindexes)

  Microbenchmarks for `[Read|Write]BlockBench` show a ~**30%**/**168%** speedup with `macOS/Clang`, and ~**19%**/**24%** with `Linux/GCC` (the follow-up XOR batching improves these further):

Pull request description:

  This PR prevents Mining interface methods from sometimes crashing when called during startup before a tip is connected. It also makes other improvements like making more RPC methods usable from the GUI. Specifically this PR:

  - Adds an `Assume` check to disallow passing negative timeout values to `Mining::waitTipChanged`
  - Makes `waitfornewblock`, `waitforblock` and `waitforblockheight` RPC methods usable from the GUI when `-server=1` is not set.
  - Changes `Mining::waitTipChanged` to return `optional<BlockRef>` instead of `BlockRef` and return `nullopt` instead of crashing if there is a timeout or if the node is shut down before a tip is connected.
  - Changes `Mining::waitTipChanged` to not time out before a tip is connected, so it is convenient and safe to call during startup, and only returns `nullopt` on early shutdowns.
  - Changes `Mining::createNewBlock` to block and wait for a tip to be connected if it is called on startup instead of crashing. Also documents that it will return null on early shutdowns.

  This allows `waitNext()` (added in https://github.com/bitcoin/bitcoin/pull/31283) to safely assume `TipBlock()` isn't `null`, not even during a scenario of early shutdown.

  Finally this PR clarifies long poll behaviour, mostly by adding code comments, but also through an early `break`.

8d801e3efb optimization: bulk serialization writes in WriteBlockUndo and WriteBlock
Similarly to the serialization reads optimization, buffered writes will enable batched XOR calculations.
This is especially beneficial since the current implementation requires copying the write input's `std::span` to perform obfuscation.
Batching allows us to apply XOR operations on the internal buffer instead, reducing unnecessary data copying and improving performance.

520965e293 optimization: bulk serialization reads in UndoRead, ReadBlock
The obfuscation (XOR) operations are currently done byte-by-byte during serialization. Buffering the reads will enable batching the obfuscation operations later.

Different operating systems handle file caching differently, so reading larger batches (and processing them from memory) is measurably faster, likely because of fewer native fread calls and reduced lock contention.

Note that `ReadRawBlock` doesn't need buffering since it already reads the whole block directly.
Unlike `ReadBlockUndo`, the new `ReadBlock` implementation delegates to `ReadRawBlock`, which uses more memory than a buffered alternative but results in slightly simpler code and a small performance increase (~0.4%). This approach also clearly documents that `ReadRawBlock` is a logical subset of `ReadBlock` functionality.

The current implementation, which iterates over a fixed-size buffer, provides a more general alternative to Cory Fields' solution of reading the entire block size in advance.

Buffer sizes were selected based on benchmarking to ensure the buffered reader produces performance similar to reading the whole block into memory. Smaller buffers were slower, while larger ones showed diminishing returns.

056cb3c0d2 refactor: clear up blockstorage/streams in preparation for optimization
Made every OpenBlockFile#fReadOnly value explicit.

Replaced hard-coded values in ReadRawBlock with STORAGE_HEADER_BYTES.
Changed `STORAGE_HEADER_BYTES` and `UNDO_DATA_DISK_OVERHEAD` to `uint32_t` to avoid casts.

Also added `LIFETIMEBOUND` to the `AutoFile` parameter of `BufferedFile`, which stores a reference to the underlying `AutoFile`, allowing Clang to emit warnings if the referenced `AutoFile` might be destroyed while `BufferedFile` still exists.
Without this attribute, code with lifetime violations wouldn't trigger compiler warnings.

3197155f91 refactor: collect block read operations into try block
Reorganized error handling in block-related operations by grouping related operations together within the same scope.

In `ReadBlockUndo()` and `ReadBlock()`, moved all deserialization operations, comments and checksum verification inside a single try/catch block for cleaner error handling.
In `WriteBlockUndo()`, consolidated hash calculation and data writing operations within a common block to better express their logical relationship.

Pull request description:

  `IsArgSet` is problematic:

  * It returns whether an arg has been set, even if it has been negated. `IsArgSet` is sometimes used to check for a truthy value, which is wrong, but usually harmless. Cleanup of those cases may or may not be done in a follow-up.
  * In most other cases, calling it is redundant, because the immediately following `Get*Arg` calls can already return an `std::optional` nullopt value to indicate an unset arg.

  So relieve both issues by removing all `IsArgSet` that are redundant.

fa2b529f92 refactor: Remove redundant call to IsArgSet
Checking for IsArgSet before calling GetArg while providing an arbitrary
default value as fallback is both confusing and fragile.

It is confusing, because the provided fallback is dead code. So it would
be better to just call GetArg without a fallback.

Even better would be to provide the true fallback value and sanitize it
as if it were user-input, but this can be done in a follow-up.

Removing the redundant call to IsArgSet will have to be done either way,
so do it now.

64a2795fd4 rpc: handle shutdown during long poll and wait methods
The waitTipChanged() now returns nullopt if the node is shutting down.

Previously it would return the last known tip during shutdown, but
this creates an ambiguous circumstance in the scenario where the
node is started and quickly shutdown, before notifications().TipBlock()
is set.

The getblocktemplate, waitfornewblock and waitforblockheight RPC
are updated to handle this. Existing behavior is preserved.

Pull request description:

  * This PR attempts to fix the duplicate coinbase weight reservation issue we currently have.
  * Fixes #21950

  We reserve 4000 weight units for coinbase transaction in `DEFAULT_BLOCK_MAX_WEIGHT`

  7590e93bc7/src/policy/policy.h (L23)

  And also reserve additional `4000` weight units in the default `BlockCreationOptions` struct.

  7590e93bc7/src/node/types.h (L36-L40)

  **Motivation**

  - This issue was first noticed during a review here https://github.com/bitcoin/bitcoin/pull/11100#discussion_r136157411)
  - It was later reported in issue #21950.
  - I also came across the bug while writing a test for building the block template. I could not create a block template above `3,992,000` in the block assembler, and this was not documented anywhere. It took me a while to realize that we were reserving space for the coinbase transaction weight twice.

  ---
  This PR fixes this by consolidating the reservation to be in a single location in the codebase.

  This PR then adds a new startup option `-blockreservedweight` whose default is `8000` that can be used to lower or increase the block reserved weight for block header, txs count, coinbase tx.

- The reserved weight of the coinbase transaction is an estimate and
  may not reflect the exact value; it can be lower.

- It should be clear that `currentblockweight` includes the reserved coinbase transaction weight.
  whereas `currentblocktx` does not account for the coinbase transaction count.

- Also clarify `m_last_block_num_txs` and `m_last_block_weight`

Pull request description:

  A test that is added as part of #30455 uncovered this issue: The `GuessVerificationProgress` function is used during during descriptor import and relies on `m_chain_tx_count`. In #29370 an [`Assume` was added](0fd915ee6b) expecting the `m_chaint_tx_count` to be set. However, as the test uncovered, `GuessVerificationProgress` is called with background sync blocks that have `m_chaint_tx_count = 0` when they have not been downloaded and processed yet.

  The simple fix is to remove the `Assume`. Users should not be thrown off by the `Internal bug detected` error. The behavior of `importdescriptor` is kept consistent with the behavior for blocks missing due to pruning.

  The test by alfonsoromanz is cherry-picked here to show that the [CI errors](https://cirrus-ci.com/task/5110045812195328?logs=ci#L2535) should be fixed by this change.

  This PR also improves error messages returned by the `importdescriptors` and `rescanblockchain` RPCs. The error message now changes depending on the situation of the node, i.e. if pruning is happening or an assumutxo backgroundsync is active.
