Pull request description:
These assertions exist to detect double-deducting values when we update descendants. However, negative fees are possible with `prioritisetransaction` so it doesn't make sense to check this.
Leave the check for sizes because those are never negative.

eeaf28dbe0e09819ab0e95bb7762b29536bdeef6 wallet: test: Failed migration cleanup (David Gumberg)
Pull request description:
Prior to https://github.com/bitcoin/bitcoin/pull/34156, an issue existed where if migration of a wallet with a relative pathname failed, the relatively specified path where the legacy wallet is would be deleted. This issue predates #32273, because the relative pathnames get stacked together, e.g. "../../", the copy conflict bug that caused migration to abort early instead of getting far enough to attempt clean-up that was fixed in #32273 is avoided.
This is a functional test demonstrating that we handle failed migration clean-up correctly for relatively-named wallets. To see the issue, you can backport this test onto 29.x: https://github.com/davidgumberg/bitcoin/tree/2026-01-07-rel-migration-test-backport
I've also added an absolute path failed migration cleanup test. WRT this and #34156, absolute paths exhibit similar behavior to unnamed wallets. Because of the name-conflict bug prior to #32273 an absolute-path migration would fail no matter what because migration would attempt to copy a file to a destination that already exists. But after #32273, absolute-path migration gets past there, and if it fails for some other reason, the same behavior that's fixed in #34156 occurs where the directory containing the wallet file is deleted.

cbf0bd35bbf312f3b13d92d281d7112e4b43b9c3 test: migration, avoid backup name mismatch in default_wallet_failure (furszy)
Pull request description:
This is a possible test failure, pushing it in case the CI starts complaining.
The change affects only test code; no cpp logic is involved.
The `test_default_wallet_failure` migration test calls the function
`migrate_and_get_rpc()`, which sets the mock time internally. But, at the
same time, the test already caches the mock time value, to later use it
in the backup existence check.
Setting the mock time twice can lead to a name mismatch during the
mentioned check (diff timestamp == diff backup names), which could
cause the test to fail.
The fix is very simple, just need to call the migration RPC directly.
Since the test expects the migration to fail, `migrate_and_get_rpc()` is
unnecessary here. I'm surprised the CI hasn't complained about this yet.

The test calls migrate_and_get_rpc(), which sets mock time internally.
The caller caches a mock time value and later relies on it to predict the
backup filename, so setting the mock time again could cause a naming
mismatch.
Fix this by calling the migration RPC directly. Since the test expects the
migration to fail, migrate_and_get_rpc() is unnecessary here.

Pull request description:
As pointed out in https://github.com/bitcoin/bitcoin/pull/34156#issuecomment-3716728670, it is possible for `createfromdump` to also accidentally delete the entire wallets directory if the wallet name is the empty string and the dumpfile contains a checksum error.
This is also fixed by removing the files created by only removing the directory for named wallets, and avoiding the use of `fs::remove_all`.

Pull request description:
Minimal fix for #34128.
The issue occurs during the migration of a legacy unnamed wallet
(the legacy "default" wallet). When the migration fails, the cleanup
logic is triggered to roll back the state, which involves erasing the
newly created descriptor wallets directories. Normally, this only
affects the parent directories of named wallets, since they each
reside in their own directories. However, because the unnamed
wallet resides directly in the top-level `/wallets/` folder, this
logic accidentally deletes the main directory.
The fix ensures that only the wallet.dat file of the unnamed wallet
is touched and restored, preserving the wallet in BDB format and
leaving the main `/wallets/` directory intact.
#### Story Line:
#32273 fixed a different set of issues and, in doing so, uncovered
this one.
Before the mentioned PR, backups were stored in the same directory
as the wallet.dat file. On a migration failure, the backup was then
copied to the top-level `/wallets/` directory. For the unnamed legacy
wallet, the wallet directory is the `/wallets/` directory, so the source
and destination paths were identical. As a result, we threw early in the
`fs::copy_file` call ([here](https://github.com/bitcoin/bitcoin/blob/29.x/src/wallet/wallet.cpp#L4572)) because the file already existed, as we
were trying to copy the file onto itself. This caused the cleanup logic
to abort early on and never reach the removal line.
#### Testing Notes:
Cherry-pick the test commit on top of master and run it. You will
see the failure and realize the reason by reading the test code.

Pull request description:
It is confusing to parse the unsigned tx version as a signed type. Also, it makes it harder to use the integer sanitizer.
Can be tested via:
* Build with the flags `-DCMAKE_C_COMPILER='clang' -DCMAKE_CXX_COMPILER='clang++' -DSANITIZERS=undefined,integer,float-divide-by-zero`
* Set the existing suppressions: `export UBSAN_OPTIONS="suppressions=$(pwd)/test/sanitizer_suppressions/ubsan:print_stacktrace=1:halt_on_error=0:report_error_type=1"`
* Start the RPC server, e.g. `./bld-cmake/bin/bitcoin-qt -datadir=/tmp -regtest -server`
* Call the sendall RPC, e.g. `./bld-cmake/bin/bitcoin-cli -datadir=/tmp -regtest -named sendall '["bcrt1qlrt3xps4wxpfcjmljrayr2ualczmnfvd4vzdq3"]' fee_rate=1.234 version=-1`

Because the default wallet has no name, the watch-only and solvables
wallets created during migration end up having no name either.
This fixes it by applying the same prefix name we use for the backup
file for an unnamed default wallet.
Before: watch-only wallet named "_watchonly"
After: watch-only wallet named "default_wallet_watchonly"
Right now, after migration the last message users see is "migration completed",
but the migration isn't actually finished yet. We still need to load the new wallets
to ensure consistency, and if that fails, the migration will be rolled back. This
can be confusing for users.
This change logs the post-migration loading step and if a wallet fails to load and
the migration will be rolled back.
The first test verifies that restoring into an existing empty directory
or a directory with no .dat db files succeeds, while restoring into a
dir with a .dat file fails.
The second test covers restoring into the default unnamed wallet
(wallet.dat), which also implicitly exercises the recovery path used
after a failed migration.
The third test covers failure during restore on a prune node. When
the wallet last sync was beyond the pruning height.
When migrating any legacy unnamed wallet, a failed migration would
cause the cleanup logic to remove its parent directory. Since this
type of legacy wallet lives directly in the main '/wallets/' folder,
this resulted in unintentionally erasing all wallets, including the
backup file.
To be fully safe, we will no longer call `fs::remove_all`. Instead,
we only erase the individual db files we have created, leaving
everything else intact. The created wallets parent directories are
erased only if they are empty.
As part of this last change, `RestoreWallet` was modified to allow
an existing directory as the destination, since we no longer remove
the original wallet directory (we only remove the files we created
inside it). This also fixes the restore of top-level default wallets
during failures, which were failing due to the directory existence
check that always returns true for the /wallets/ directory.
This bug started after:
f6ee59b6e2
Previously, the `fs::copy_file` call was failing for top-level wallets,
which prevented the `fs::remove_all` call from being reached.
Track what RestoreWallet creates so only those files and directories
are removed during a failure and nothing else. Preexisting paths
must be left untouched.
Note:
Using fs::remove_all() instead of fs::remove() in RestoreWallet does
not cause any problems currently, but the change is necessary for the
next commit which extends RestoreWallet to work with existing directories,
which may contain files that must not be deleted.

Pull request description:
Part of #30289, follow-up to #32545.
This gets rid of `FixLinearization()` by integrating the functionality into `Linearize()`, and makes txgraph exploit that (by delaying fixing of clusters until their first re-linearization). It also reduces (but does not eliminate) the number of calls to `PostLinearize`, as the SFL linearization effectively performs something very similar to postlinearization when loading in an existing linearization already.

Pull request description:
The ctest target `bench_sanity_check` has many issues:
* With sanitizers enabled, it is one of the slowest targets, often taking several minutes. See https://github.com/bitcoin/bitcoin/issues/32770#issuecomment-2984264066.
* There is no insight from ctest into how long each individual sanity check takes.
* On a timeout, or OOM issue, there is no insight into which sub-bench failed. The failure will generally just look like `75/153 Test #9: bench_sanity_check ...................***Failed 770.84 sec out of memory`
* Places that can't use ctest (like the Windows-cross CI task) have to explicitly run it, or risk forgetting to run it.
* All benchmarks are run sequentially, when they could run in parallel instead.
Both issues can lead to CI timeouts and leave CPU unused during testing.
Fix all issues by running it as part of the functional tests instead. This is similar to the rpcauth tests (https://github.com/bitcoin/bitcoin/pull/32881) and util tests [bitcoin-tx, and bitcoin-util] (https://github.com/bitcoin/bitcoin/pull/32697).

4ce3f4a26565e9851af950728cda7bcc2242d0c2 rpc, net: deprecate `startingheight` field of `getpeerinfo` RPC (Sebastian Falbesoner)
Pull request description:
This PR deprecates the "startingheight" result field of the `getpeerinfo` RPC, following the discussion in #33990.
Rationale: the reported starting height of a peer in the VERSION message is untrusted, and it doesn't seem to be useful anymore (after #20624), so deprecating the corresponding field seems reasonable. After that, it can be removed, along with the `m_starting_height` field of the Peer / CNodeStats structs, as it is sufficient to show the reported height only once at connection in the debug log.

5805a8b54083539c4fede52b4b726102dcfc864e psbt: detect invalid MuSig2 pubkeys in deserialization (rkrux)
Pull request description:
Throw error while deserializing PSBT if invalid pubkeys are passed
as a MuSig2 aggregate or participant.
Should fix#33999 & #34201 by throwing error at the very start while decoding
an invalid PSBT that should subsequently not allow the MuSig2
signing operation to take place, thereby avoiding the crash.

With the new SFL algorithm, the process of loading an existing linearization into the
SFL state is very similar to what PostLinearize does. This means there is little benefit
to performing an explicit PostLinearize step before linearizing inside txgraph. Instead,
it seems better to use our allotted CPU time to perform more SFL optimization steps.
With the SFL algorithm, we will practically be capable of keeping
most if not all clusters optimal. With that, it seems less valuable
to avoid doing work after splitting an acceptable cluster, because by
doing some work we may get it to OPTIMAL.
This reduces the complexity of the code a bit as well.
fac5a1b10a6979a7898c5c3555d62b593560772f test: Allow mempool_updatefromblock.py to run on 32-bit (MarcoFalke)
Pull request description:
The number of dropped parent transactions in the `test_max_disconnect_pool_bytes` test was hard-coded to `2`.
This happens to work fine on 64-bit for now. However, it seems to fail on 32-bit (https://github.com/bitcoin/bitcoin/issues/34108).
I don't think we care about the exact number, as long as it is at least `1`.
So hard-code `1` for an initial sanity check, and then calculate the exact value at runtime via `len(mempool) // 2`.
Also, enable the functional tests in 32-bit CI, to confirm the regression test.
Fixes https://github.com/bitcoin/bitcoin/issues/34108

Due to the mocktime being bumped before the expected time is updated,
it could happen that the self-announcement is send with an newer
timestamp than what we expect. To fix this, update the expected time
before we bump the mocktime.

fab300b378941a233119805c0d62198596a57790 test: Enable ruff E713 lint (MarcoFalke)
Pull request description:
Membership tests of the form `not item in stuff` may be confusing, because they could be read as `(not item) in stuff`, which is different.
So enable the ruff E713 lint, which should also help to avoid having to go through review cycles for this.

The reported starting height of a peer in the VERSION message is
untrusted, and it doesn't seem to be useful anymore (after #20624),
so deprecating the corresponding "startingheight" field seems
reasonable. After that, it can be removed, along with the
`m_starting_height` field of the Peer / CNodeStats structs, as it is
sufficient to show the reported height only once at connection in the
debug log.
6da6f503a6dd8de85780ca402f5202095aa8b6ea refactor: Let CCoinsViewCache::BatchWrite return void (TheCharlatan)
Pull request description:
CCoinsViewCache::BatchWrite always returns true if called from a backed cache, so just return void instead. Also return void from ::Sync and ::Flush.
This allows for dropping a FatalError condition and simplifying some dead error handling code a bit.
Since we now no longer exercise the "error path" when returning from `CCoinsView::BatchWrite`, make the method clear the cache instead. This should only be exercised by tests and not change production behaviour. This might slightly improve the coins_view fuzz test's ability to generate better coverage.

76c092ff805833a9adf84f669f0455bc2e0bba8b wallet: warn against accidental unsafe older() import (Sjors Provoost)
592157b7594693da389e4bd9b2cdedbdba7556fc test: move SEQUENCE_LOCKTIME flags to script (Sjors Provoost)
Pull request description:
[BIP 379](https://github.com/bitcoin/bips/blob/master/bip-0379.md) ([Miniscript](https://bitcoin.sipa.be/miniscript/)) allows relative height and time locks that have no consensus meaning in [BIP 68](https://github.com/bitcoin/bips/blob/master/bip-0068.mediawiki) (relative timelocks) / [BIP 112](https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki) (`CHECKSEQUENCEVERIFY`). This is (ab)used by some protocols, e.g. [by Lightning to encode extra data](https://delvingbitcoin.org/t/exploring-extended-relative-timelocks/1818/23), but is unsafe when used unintentionally: `older(65536)` is equivalent to `older(1)`.
This PR emits a warning when `importdescriptors` contains such a descriptor.
The first commit makes `SEQUENCE_LOCKTIME` flags reusable by other tests.
The main commit adds the `ForEachNode` helper to `miniscript.h` which is then used in the `MiniscriptDescriptor` constructor to check for `Fragment::OLDER` with unsafe values. These are stored in `m_warnings`, which the RPC code then collects via `Warnings()`.
It adds both a unit and functional test.
---
A previous version of this PR prevented the import, unless the user opted in with an `unsafe` flag. It also used string parsing in the RPC code.

77c9b3c08f5f195c9afe8fba2395fbe48068fce0 change test_runner.py to be cwd independent by calling subprocess.run with cwd arg. (Robin David)
Pull request description:
Dear Maintainers,
While using `test_runner.py` that runs fuzz tests and produces coverage results I encountered the following error.
If not running the script from the project root directory the `git grep --function-context [...]` does not return the same output which results in the following Python error:
```
../../src/protocol.h-', '../../../src/protocol.h-/** nServices flags */']
Traceback (most recent call last):
File "/path/to/bitcoin/build_libfuzzer/test/fuzz/./test_runner.py", line 405, in <module>

File "/path/to/build_libfuzzer/test/fuzz/./test_runner.py", line 218, in transform_process_message_target
assert len(lines)
~~~^^^^^^^
AssertionError
```
The script is not able to retrieve lines as the filter applied is:
```python
lines = [l.split("::", 1)[1].split(",")[0].lower() for l in lines if l.startswith("src/protocol.h- NetMsgType::")]
```
Which when running from the root directory returns:
```
[snip]
src/protocol.h- NetMsgType::VERSION,
[snip]
```
but returns a relative path to CWD when run from other directories e.g:
```
../../../src/protocol.h- NetMsgType::VERSION,
```
This is very unfortunate as the script rightfully read the `config.ini` relatively to itself and go fetch `BUILDDIR` and `SRCDIR` variables to obtain absolute paths.
Options are:
* enforce running the script from *bitcoin/* directory (and thus explicitly mentioning it in the doc)
* make the script independent from where it is being run
I chose the second option as it was fairly easy to make the script independent from where it is being run.

Pull request description:
`IsWellFormedPackage()` already claims: "parents must appear before children." In practice the `require_sorted` argument was always passed as `true`, making the false-path dead code. It was introduced that way from the beginning in https://github.com/bitcoin/bitcoin/pull/28758/files#diff-f30090b30c9489972ee3f1181c302cf3a484bb890bade0fd7c9ca92ea8d347f6R79.
