2b00030af8 interfaces, chain, refactor: Remove inaccurate getActiveChainLocator (pablomartin4btc)
110a0f405c interfaces, chain, refactor: Remove unused getTipLocator (pablomartin4btc)
Pull request description:
Remove `Chain::getTipLocator`, `Chain::GetLocator()`, and `Chain::getActiveChainLocator`:
- `Chain::getTipLocator` is no longer used.
- `Chain::GetLocator`, replaced its call by `GetLocator()`, which uses `LocatorEntries`, avoiding direct access to the chain itself (change suggested by l0rinc while reviewing this PR to maintain consistency with the overall refactoring).
- `Chain::getActiveChainLocator`, whose name was misleading, has functionality redundant with Chain::findBlock.
- Additionally, the comment for getActiveChainLocator became inaccurate following changes in commit ed470940cd (from PR #25717).
This is a [follow-up](https://github.com/bitcoin/bitcoin/pull/29652#issuecomment-3151665095) to #29652.

This is the final leg of the [type safety refactor](https://github.com/bitcoin/bitcoin/pull/32189).
All of these changes are straightforward `uint256` --> `Txid` along with any necessary explicit conversions. Also, `transaction_identifier.h` is moved to primitives in the last commit, as `Txid` and `Wtxid` become fundamental types after this PR.

The getActiveChainLocator method name was misleading, and its functionality
duplicated `Chain::findBlock`. This commit removes the method and replaces
all its usages with direct `Chain::findBlock` calls.
Additionally, the comment of getActiveChainLocator has been outdated since
commit ed47094 from #25717.
Finally, in CWallet::ScanForWalletTransactions, the findBlock calls are now
unified into a single call at the start of the function.

with GetLocator() which uses LocatorEntries instead.

Pull request description:
Because we do not discourage nodes for transactions we consider non-standard, we don't get any DoS protection from this check in adversarial scenarios, so remove the check entirely both to simplify the code and reduce the risk of splitting the network due to changes in tx relay policy.
Then, because we no longer make use of the distinction between consensus and standardness failures during script validation, don't re-validate each script with only-consensus rules, reducing the cost to us of transactions that we won't relay.

Pull request description:
Noticed while reviewing https://github.com/bitcoin/bitcoin/pull/31287#discussion_r1843809721 that the [default wallet] part of progress messages remains untranslated while the rest of the string is translated.
Fix this in all places where `CWallet::ShowProgress` (which has a cancel button) and `Chain::showProgress` (which doesn't have a cancel button) are called by making "default wallet" into a translated string.

Moves the file from `src/util` to `src/primitives`. Now that the
refactor is complete, Txid and Wtxid are fundamental types, so it
makes sense for them to reside in `src/primitives`.
These remaining miscellaneous changes were identified by commenting out
the `operator const uint256&` conversion and the `Compare(const uint256&)`
method from `transaction_identifier.h`.
ca64b71ed5 test: fix scripts in `blockfilter_basic_test` (UdjinM6)
Pull request description:
`std::vector` fill ctor is like this:
```
// Constructs a vector with `count` copies of elements with value `value`.
explicit vector( size_type count, const T& value = T(), const Allocator& alloc = Allocator() ); // (until C++11)
vector( size_type count, const T& value, const Allocator& alloc = Allocator() ); // (since C++11)(constexpr since C++20)
```
https://en.cppreference.com/w/cpp/container/vector/vector.html
i.e. `std::vector<unsigned char>(0, 65)` means a vector with `0` copies of `65` which feels wrong. I believe `count` and `value` were swapped in `blockfilter_basic_test` scripts.

9014d4016a tests: add sighash caching tests to feature_taproot (Pieter Wuille)
Pull request description:
This introduces a per-txin cache for sighash midstate computation to the script interpreter for legacy (bare), P2SH, P2WSH, and (as collateral effect, but not actually useful) P2WPKH. This reduces the impact of certain types of quadratic hashing attacks that use standard transactions. It is not known to improve the situation for attacks involving non-standard transaction attacks.
The cache works by remembering for each of the 6 sighash modes a `(scriptCode, midstate)` tuple, which gives a midstate `CSHA256` object right before the appending of the sighash type itself (to permit all 256, rather than just the 6 ones that match the modes). The midstate is only reused if the `scriptCode` matches. This works because - within a single input - only the sighash type and the `scriptCode` affect the actual sighash used.
The PR implements two different approaches:
* The initial commits introduce the caching effect always, for both consensus and relay relation validation. Despite being primarily intended for improving the situation for standard transactions only, I chose this approach as the code paths are already largely common between the two, and this approach I believe involves fewer code changes than a more targetted approach, and furthermore, it should not hurt (it may even help common multisig cases slightly).
* The final commit changes the behavior to only using the cache for non-consensus script validation. I'm open to feedback about whether adding this commit is worth it.
Functional tests are included that construct contrived cases with many sighash types (standard and non-standard ones) and `OP_CODESEPARATOR`s in all script types (including P2TR, which isn't modified by this PR).

d3b8a54a81 Refactor CFeeRate to use FeeFrac internally (Pol Espinasa)
Pull request description:
The `FeeFrac` type represents a fraction, intended to be used for `sats/vbyte` or `sats/WU`. It was added to improve accuracy when evaluating fee rates in cluster mempool. [1]
But it can also be used to fix the precision issues that the current `CFeeRate` class has now.
At the moment, `CFeeRate` handles the fee rate as satoshis per kilovirtualbyte: `CAmount / kvB` using an integer.
This PR fix `CFeeRate` precision issues by encapsulating `FeeFrac` internally keeping backwards compatibility.
This PR can also be used as a based to use multiple units on RPC calls as detailed in this issue [2].

Previously, we would check failing input scripts twice when considering
a transaction for the mempool, in order to distinguish policy failures
from consensus failures. This allowed us both to provide a different
error message and to discourage peers for consensus failures. Because we
are no longer discouraging peers for consensus failures during tx relay,
and because checking a script can be expensive, only do this once.
Also renames non-mandatory-script-verify-flag error to
mempool-script-verify-flag-failed.
Do not discourage nodes even when they send us consensus invalid
transactions.
Because we do not discourage nodes for transactions we consider
non-standard, we don't get any DoS protection from this check in
adversarial scenarios, so remove the check entirely both to simplify the
code and reduce the risk of splitting the network due to changes in tx
relay policy.
exFAT is known to cause corruption on macOS. See #28552.
Therefore we should warn when using this fs format for either the blocks
or data directories on macOS.

27aefac425 validation: detect witness stripping without re-running Script checks (Antoine Poinsot)
2907b58834 policy: introduce a helper to detect whether a transaction spends Segwit outputs (Antoine Poinsot)
eb073209db qa: test witness stripping in p2p_segwit (Antoine Poinsot)
Pull request description:
Since it was introduced in 4eb515574e (#18044), the detection of a stripped witness relies on running the Script checks 3 times. In the worst case, this consists in running Script validation for every single input 3 times.
Detection of a stripped witness is necessary because in this case wtxid==txid, and the transaction's wtxid must not be added to the reject filter or it could allow a malicious peer to interfere with txid-based orphan resolution as used in 1p1c package relay.
However it is not necessary to run Script validation to detect a stripped witness (much less so doing it 3 times in a row). There are 3 types of witness program: defined program types (Taproot, P2WPKH and P2WSH), undefined types, and the Pay-to-anchor carve-out.
For defined program types, Script validation with an empty witness will always fail (by consensus). For undefined program types, Script validation is always going to fail regardless of the witness (by standardness). For P2A, an empty witness is never going to lead to a failure.
Therefore it holds that we can always detect a stripped witness without re-running Script validation. However this might lead to more "false positives" (cases where we return witness stripping for an otherwise invalid transaction) than the existing implementation. For instance a transaction with one P2PKH input with an invalid signature and one P2WPKH input with its witness stripped. The existing implementation would treat it as consensus invalid while the implementation in this PR would always consider it witness stripped.
h/t AJ: this essentially implements a variant of https://github.com/bitcoin/bitcoin/pull/33066#issuecomment-3135258539.

cd97905ebc cmake: Move internal binaries from bin/ to libexec/ (Ryan Ofsky)
Pull request description:
This change moves binaries that are not typically invoked directly by users from the `bin/` directory to the `libexec/` directory in CMake installs and binary releases. The goal of the PR is to introduce a distinction between internal and external binaries so starting with #31802, we can use IPC to implement features in new binaries without adding those binaries to the CLI. The change also helps reduce clutter in `bin/`, making it easier for users to identify useful tools to run. Summary of changes:
- For **source builds** (i.e. developer builds) — There are no changes.
- For **source installs** (i.e. `cmake --install` result) — `test_bitcoin`, `test_bitcoin-qt`, and `bench_bitcoin` are installed in `${CMAKE_PREFIX_PATH}/libexec` instead of `${CMAKE_PREFIX_PATH}/bin`, so they are no longer on the system `PATH`. However, they can still be invoked from the `libexec/` directory, or from the CLI as `bitcoin test`, `bitcoin test-gui`, and `bitcoin bench`, respectively.
- For **binary releases** — Since `test_bitcoin` is the only test binary enabled in releases, the only change is moving `test_bitcoin` from `bin/` to `libexec/`.

fdbade6f8d kernel: create monolithic kernel static library (Cory Fields)
Pull request description:
Currently, consuming `libbitcoinkernel.a` requires all its dependency static libraries to be available. A switch to a monolithic variant, which contains object files from its dependencies, was discussed in the Kernel WG. The necessary preparations in the libsecp256k1 build scripts were completed in https://github.com/bitcoin-core/secp256k1/pull/1678, which are now available in this repository since https://github.com/bitcoin/bitcoin/pull/33036.
The changes in this PR were picked from https://github.com/theuni/bitcoin/commits/static_kernel/, with an additional adjustment in `libbitcoinkernel.pc.in`.

Pull request description:
This PR:
1. Moves handling of Qt TS files into the `locale` directory.
2. Switches from inferior globbing to the explicit file list generated by the [`bitcoin-maintainer-tools/update-translations.py`](https://github.com/bitcoin-core/bitcoin-maintainer-tools/blob/main/update-translations.py) script.
Closes#32653.

ad132761fc [allocators] Apply manual ASan poisoning to PoolResource (dergoegge)
Pull request description:
Currently ASan will not detect use-after-free issues for memory allocated by a `PoolResource`. This is because ASan is only aware of the memory chunks allocated by `PoolResource` but not the individual "sub-chunks" within.
E.g. this test will not produce an ASan error even though the referenced coin has been deallocated:
```c++
diff --git a/src/test/coins_tests.cpp b/src/test/coins_tests.cpp
index c46144b34b..aa6ca15ce1 100644

Fix this by applying [manual ASan poisoning](https://github.com/google/sanitizers/wiki/AddressSanitizerManualPoisoning) for memory allocated by `PoolResource`:
* Newly allocated chunks are poisoned as a whole
* "Sub-chunks" are unpoisoned/re-poisoned during allocation/deallocation
With the poisoning applied, ASan catches the issue in the test above:
```
$ ./build_unit/bin/test_bitcoin --run_test="coins_tests/asan_uaf"

1252eeb997 rpc: fix getpeerinfo ping duration unit docs (0xb10c)
Pull request description:
The docs have been incorrect since a3789c700b (released in v25; master since Sept. 2022). Noticed while setting up monitoring using getpeerinfo.

When the detailed peers list is requested, return the shortened services in the
-netinfo header in the same format as the "serv" column, instead of the full names
list in the report.
The getpeerinfo docs incorrectly specified the ping durations as
milliseconds. This was incorrectly changed in a3789c700b
(released in v25; master since Sept. 2022). The correct duration unit
is seconds.
Also, remove the documentation of the getpeerinfo RPC response from the
ping RPC since it's incomplete. Better to just reference the getpeerinfo
RPC and it's documenation for this.
