c011e3aa542631a8857039df796ebf13a653e8a6 test: Wrap validation functions with TestChainstateManager (Martin Zumsande)
Pull request description:
This adds a fuzz target for the block index and various events in validation that interact with it.
It can create arbitrary tree-like structure of block indexes, simulating (so far) the following events:
- Adding a header
- Receiving the full block (may be valid or not)
- `ActivateBestChain()` - Reorging the chain to a new chain tip (possibly encountering invalid blocks on the way)
- Pruning a block in the best chain
- Receiving a previously pruned block again (`getblockfrompeer`)
It might be interesting / possible to extend this to more events, such as dealing with more than one chainstate (assumeutxo).
The test skips all actual validation of header/ block / transaction data by just simulating the outcome, and also doesn't interact with the data directory.
The main goal is to ensure the integrity of the block index tree in all fuzzed constellations, by calling `CheckBlockIndex()` at the end of each iteration.
Compared to #29158 this approach has a more limited scope (by skipping all actual validation), but it is fast - it doesn't do a full init sequence on each iteration, but "cleans up" after itself by resetting the global validation state after each iteration.

facd3d56ccbe2414a5f2b75be7132cd8b904f1e9 log: Use `__func__` for -logsourcelocations (MarcoFalke)
Pull request description:
The `-logsourcelocations` option was recently changed to print the full function signature, as a side-effect of moving toward `std::source_location` internally.
This is fine, but at least for me, it makes debugging functional test failures harder, because the log is just so massively verbose, with questionable benefit.
I think the historically used file name, line number, and plain `__func__` name are more than sufficient for `-logsourcelocations`.
So switch back to using that.
For reference, a verbose log may look like:
```
...

n uses 1 additional threads
...
```
I don't think there is value in printing stuff, like the (anon) namespace, the class template args, or the functionn (template) args. The following should be more than sufficient:

Pull request description:
### Summary
Instead of counting occurrences in sets and maps, the C++20 `::contains` method expresses the intent unambiguously and can return early on first encounter.
### Context
Applied clang‑tidy's [readability‑container‑contains](https://clang.llvm.org/extra/clang-tidy/checks/readability/container-contains.html) check, though many cases required manual changes since tidy couldn't fix them automatically.
### Changes
The changes made here were:
| From | To |
|------------------------|------------------|
| `m.find(k) == m.end()` | `!m.contains(k)` |
| `m.find(k) != m.end()` | `m.contains(k)` |
| `m.count(k)` | `m.contains(k)` |
| `!m.count(k)` | `!m.contains(k)` |
| `m.count(k) == 0` | `!m.contains(k)` |
| `m.count(k) != 1` | `!m.contains(k)` |
| `m.count(k) == 1` | `m.contains(k)` |
| `m.count(k) < 1` | `!m.contains(k)` |
| `m.count(k) > 0` | `m.contains(k)` |
| `m.count(k) != 0` | `m.contains(k)` |
> Note that `== 1`/`!= 1`/`< 1` only apply to simple [maps](https://en.cppreference.com/w/cpp/container/map/contains)/[sets](https://en.cppreference.com/w/cpp/container/set/contains) and had to be changed manually.
There are many other cases that could have been changed, but we've reverted most of those to reduce conflict with other open PRs.

fa904fc683c0892eb800ddb986fdc0c646721077 lint: Remove confusing, redundant, and brittle lint-spelling (MarcoFalke)
Pull request description:
`codespell` was a fun experiment. However, it has many issues, when used in this project:
* The number of false-positives and true-positives are in the same ballpark. There are also many false-negatives, so the overall net-benefit is questionable.
* There is often confusion around spelling errors leading to a failing CI (they do not, which was intended).
* LLMs released this year are capable to detect typos with less false-positives and less false-negatives, so the `codespell` integration is a bit redundant in that sense.
Fix all issues by removing it.
Going forward, anyone is free to continue to use `codespell`, or any LLM, or any other tool, locally. Also, DrahtBot has the LLM typo linter integrated in the summary comment. I think the options are plenty, and are more than sufficient for now.

faa8ee62f5c1606217fbe9eacdd504ec133920a4 ci: Pin native tests on cross-builds to same commit (MarcoFalke)
Pull request description:
After commit 13809b867ad980a12f886316b18bb2d3d2848ac2, the native tests may check out a different commit than the cross-build task that produced the artefacts they run on.
Obviously, this may lead to test failures.
Fix it, by first determining a fixed commit, to be used for both the build and the native tests.
An alternative could be to fully or partially revert 13809b867ad980a12f886316b18bb2d3d2848ac2, but that comes again with the downsides making it harder to detect silent merge conflicts by re-running CI, or clearing unrelated and fixed intermittent test issues by re-running CI. Then, the only alternative would be to close and re-open the pull request.

This imitates the use of the getblockfrompeer rpc.
Note that currently pruning is limited to blocks in the active chain.
Co-authored-by: Martin Zumsande <mzumsande@gmail.com>
This fuzz target creates arbitrary tree-like structure of indices,
simulating the following events:
- Adding a header to the block tree db
- Receiving the full block (may be valid or not)
- Reorging to a new chain tip (possibly encountering invalid blocks on
the way)
- pruning
The test skips all actual validation of header/ block / transaction data
by just simulating the outcome, and also doesn't interact with the data directory.
The main goal is to test the integrity of the block index tree in

7e9de20c0c144f5ccea5efe6d90601dd72bc7461 fuzz: exercise `ComputeMerkleRoot` without mutated parameter (Lőrinc)
Pull request description:
The `mutated` parameter in `ComputeMerkleRoot` unlocks a different path that was always exercised in the fuzz test.
Adjusted to be fuzzer to pass `nullptr` as well to make sure that path is also tested: 24ed820d4f/src/consensus/merkle.cpp (L49-L53)

Pull request description:
This PR contains the first part of #28608, which tries to make assumeutxo code more maintainable, and improve it by not locking `cs_main` for a long time when the snapshot block is connected, and by deleting the snapshot validation chainstate when it is no longer used, instead of waiting until the next restart.
The changes in this PR are just refactoring. They make `Chainstate` objects self-contained, so for example, it is possible to determine what blocks to connect to a chainstate without querying `ChainstateManager`, and to determine whether a Chainstate is validated without basing it on inferences like `&cs != &ActiveChainstate()` or `GetAll().size() == 1`.
The PR also tries to make assumeutxo terminology less confusing, using "current chainstate" to refer to the chainstate targeting the current network tip, and "historical chainstate" to refer to the chainstate downloading old blocks and validating the assumeutxo snapshot. It removes uses of the terms "active chainstate," "usable chainstate," "disabled chainstate," "ibd chainstate," and "snapshot chainstate" which are confusing for various reasons.

09dfa4d3f8dfbea61a73d4add79e2464ca776571 test: fix race condition in p2p_v2_misbehaving.py peerid assertion (stratospher)
Pull request description:
Remove the hard-coded peer id from the debug message in `p2p_v2_misbehaving.py`.
asyncio's non-deterministic task scheduling might cause [peer2](938d7aacab/test/functional/p2p_v2_misbehaving.py (L181))'s connection to happen before [peer1](938d7aacab/test/functional/p2p_v2_misbehaving.py (L179))'s. since we test that peer2 [remains connected](938d7aacab/test/functional/p2p_v2_misbehaving.py (L182)), any disconnection must originate from peer1, making the specific peer id not necessary for test correctness. so we can remove the hard coded peer id from the expected debug log message.
Fixes#34035.

Pull request description:
Some users will have a backup of their legacy wallet. These cannot be restored since the "Restore Wallet" action expects to be able to load the wallet after restoring, and this fails for legacy wallets now that they are deleted. Furthermore, the "Migrate Wallet" action only allows users to migrate wallets that are in the wallets directory, so such backups cannot be migrated from the GUI.
This PR resolves this issue by adding a menu item in the "Migrate Wallet" menu which allows users to select their backup file so that it will first be restored but not loaded, and then migrated.

Pull request description:
`LogPrintLevel` has many issues:
* It encourages to log several levels in one source location. This is problematic, because all levels (even warnings and errors) will be rate limited equally for the same location.
* Its warning and error logs are specially formatted compared to all other warning and error logs in the codebase, making them harder to spot (both in the debug log and in the code).
* It is verbose to type and read.
* It is confusing, because the majority of code uses the `Log$LEVEL(...)` macros. Having less ways to achieve the same makes the code more consistent and easier to review.
Fix all issues by removing it

Addresses two issues in the `clusterlin_postlinearize_tree` target:

2. We were accidentally passing in `post_linearization` to `PostLinearize` instead of the copy we just made, resulting in an ineffective check.

Suggested by @l0rinc in #34004
Message by @l0rinc:
This adds a consteval constructor to transaction_identifier (Txid/Wtxid) to allow parsing hex strings at compile-time.
This replaces runtime FromHex checks in tests, ensuring that malformed hardcoded hashes cause build failures rather than runtime test failures.
Test variables are explicitly marked constexpr. This is required to workaround a regression in GCC 14 (Bug 117501) where the compiler incorrectly flags consteval initialization of non-constexpr variables as "statements with no effect".
GCC Bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117501

The test was a bit confusing, because it just referred to the "global
log level" without explicitly specifying what it is. The level is set
though the LogSetup constructor. However, it is easier to follow unit
tests, if they are self-contained. So just set the level to Debug
explicitly here.
Also, add a new debug_3 log, to further document the intended behavior
of the unit test.
Also, replace the LogPrintLevel with the shorter and exact replacements
LogTrace and LogDebug.
Avoids ratelimiting unconditional log statements when debug logging
is enabled. Introduces slight behaviour change by removing
the category from unconditional logs, making them more uniform
with the other unconditional logs in the codebase.
Also, in a slight behavior change, prefix the info-level (and higher)
messages with "ipc:".

The test intends to verify that running `PostLinearize` a
second time on a tree-structured graph doesn't change the
result. But `PostLinearize` was being called on the original
variable, not the copy. So the check was comparing the
unmodified copy against itself, which is useless.
Fix by post-linearizing the correct variable.
The dependency graphs generated by this test can have holes
(unused indices) in them. This means some of the transactions
were skipped when using `depgraph_gen.TxCount()` as the upper
bound of the loop. Switch to using `depgraph.Positions()` to
correctly handle sparse graphs.
due to asyncio's non-deterministic task scheduling, peer2's
connection might happen before peer1's, causing peer2 to get
assigned peer_id=1 on bitcoind side and peer1 to get assigned
peer_id=2 on bitcoind side.
since we test that peer2 remains connected, any disconnection
must originate from peer1, making the specific peer id unnecessary
for test correctness. so we can remove the specific peer_id from
the expected debug log.

Pull request description:
Cuts out some wasted time in net socket handling. First, only calculates the current time once every 50ms, rather than once for each peer, which given we only care about second-level precision seems more than adequate. Second, caches the value of the `-capturemessages` setting in `CConnman` rather than re-evaluating it every time we invoke `PushMessaage`.
