1dd0923677 refactor: Track BnB selection by index (Ben Woosley)
Pull request description:
This is prompted by #13167 and presented as a friendly alternative to it.
IMO you can improve code readability and performance by about 20% by tracking the selected utxos by index, rather than by position. This reduces the storage access complexity from roughly O(utxo_size) to O(selection_size).

*"The lack of string context in Transifex is a real problem for this project, as proper context (dev notes and/or screenshots) are essential to achieve quality translations."*
This pull adds developer notes for transifex translators via `extracomment` tags, and it improves the existing ones and their tooltips with more context, clarity and completeness for the following peer tab fields as a follow-up to bitcoin-core/gui#526:
- address relay
- addresses processed
- addressed rate-limited
It looks like only six lines of diff, but they are loooong lines.
If this is the right direction, the same can be done for other fields in follow-ups.

f59bee3fb2 fuzz: execute each file in dir without fuzz engine (Anthony Towns)
Pull request description:
Phony fuzzing (phuzzing)! Run the fuzz testing code against known inputs to detect errors. Advantage is you can easily test using the existing qa-assets datasets without having to compile with fuzzing enabled; disadvantage is that it doesn't do any actual fuzzing.
Example usage:
```
$ for a in ${QA_ASSETS}/fuzz_seed_corpus/*; do echo ${a##*/}; done | xargs -P8 -I {} /bin/sh -c "FUZZ={} test/fuzz/fuzz ${QA_ASSETS}/fuzz_seed_corpus/{}"
No fuzzer for address_deserialize.

addition_overflow: succeeded against 848 files in 0s.
asmap: succeeded against 981 files in 0s.
checkqueue: succeeded against 211 files in 0s.
...
```
(`-P8` says run 8 of the tasks in parallel)
If there are failures, the first one will be reported and the program will abort with output like:
```

2efdfb88aa gui: restore Send for external signer (Sjors Provoost)
4b5a6cd149 refactor: helper function signWithExternalSigner() (Sjors Provoost)
026b5b4523 move-only: helper function to present PSBT (Sjors Provoost)
Pull request description:
Fixes#551
For the simplest use case of a wallet with one external signer and "PSBT Controls" disabled in settings (the default), the send dialog will behave the same as when using a wallet with private keys. I.e. there's no "Create Unsigned" button.
When PSBT controls are turned on, you can now actually make a PSBT with signing it; before this PR that button would trigger a sign event and would broadcast the transaction.
In case a multisig, the Send button will sign on the device, and then fall back to presenting a PSBT (same behavior as before #441).
This PR starts with two refactoring commits to move some stuff into a helper function for improved readability in general, and to make the main commit easier to review.

Before this change the send confirmation dialog would keep the Send option disabled. The Create Unsigned choice would actually send. This is potentially confusing.
With this change the Create Unsigned button will not attempt to sign and always produce a PSBT. The Send button will attempt to sign, and only return a PSBT if more signatures are needed.
When using an external signer, the Create Unsigned option only appears when PSBT controls are enabled in the wallet settings.
This commit maintains the pre-existing behavior of filling the PSBT (without signing) even when not using an external signer.
Closes#551

fa4e30b0f3 policy: Remove unused locktime flags (MarcoFalke)
Pull request description:
The locktime flags have many issues:
* They are passed in by a default argument, which is fragile. It has already lead to bugs like the one fixed in commit e30b6ea194.
* They are negative (signed), which doesn't make sense for flags (unsigned in general). According to the review comments when the code was added: "The max on the flags is a fairly weird operation." (https://github.com/bitcoin/bitcoin/pull/6566#issuecomment-150310861)
* No call site relies on the default argument and they all pass in a single compile-time constant, rendering most of the code dead and untested.
* The dead code calls `GetAdjustedTime` (network adjusted time), which has its own issues. See https://github.com/bitcoin/bitcoin/issues/4521
Fix all issues by removing them

This is a performance optimization - rather than track all visited values
in a bool vector, track the selected index in a vector. This results in a
complexity reduction of O(utxo_size) to O(selection_size).

5ce3057c8e test: set segwit height back to 0 on regtest (Martin Zumsande)
Pull request description:
The change of `consensus.SegwitHeight` from 0 to 1 for regtest in #22818 had the effect that if I create a regtest enviroment with current master (or 23.x), and then try to load this chain with an older version (22.x), I get an InitError
`Witness data for blocks after height 0 requires validation. Please restart with -reindex`
and have to reindex because `BLOCK_OPT_WITNESS` is no longer set for the Genesis block and `NeedsRedownload()` in validation returns `true` with an older version.
That might be a bit annoying for tests that use a shared regtest dir with different versions.
If people think this is enough of an issue to be worth fixing, I think it should also make it into 23.x

#22009 introduced a `GetSelectionWaste()` function to determine how much "waste" a coin selection solution has, and is a mirror of the waste calculated inside of `SelectCoinsBnB()`. It would be bad for these two waste metrics to deviate, since it could negatively affect how often we select the BnB solution. Add an assertion to help tests catch a potential accidental change.

These two implementations of waste calculation should never deviate.
Still keep the SelectCoinsBnB internal calculation because incremental
calculate-as-you-go is much more performant than calling
GetSelectionWaste() over and over again.
This was changed in #22818 from 0 to 1. Since it changes
BLOCK_OPT_WIT of the genesis block, older versions of bitcoin
core would not read regtest directories created with newer versions
without a reindex.
b7dbc83f23 qt: Remove network detection based on address in BIP21 (laanwj)
Pull request description:
This is removes some ugly and brittle code that switches the global network to testnet based on a provided address. I think in practice it's very unlikely for testnet BIP21 payment URIs to be used, and if so it's for testing so it's easy enough to manually copy it. Or to specify `-testnet` explicitly.
There is already no such case for `-regtest` or `-signet`.
After this change it will only accept addresses for the explicitly selected network. Others will result in a "wrong network" popup.
There is also a possibility for refactor after this as the initialization order of `PaymentServer::ipcParseCommandLine` isn't important anymore (well, it still has to be before `PaymentServer::ipcSendCommandLine`, maybe even merged with it), but I have not done so here.

8ea6167099 wallet: refactor: dedup sqlite blob binding (Sebastian Falbesoner)
Pull request description:
This refactoring PR deduplicates repeated SQLite blob binding to a statement with a newly introduced helper function `BindBlobToStatement`, abstracting away the calls to `sqlite3_bind_blob(...)`.
This should be more readable and less error-prone, e.g. in case that the error handling has to be adapted. As a slight drawback, the function where the binding happens is not printed anymore (`__func__`), i.e. one could argue this is not strictly a refactoring, but IMHO the advantages of deduplication outweigh this; binding errors are purely internal logic errors (wrong use of the sqlite API) rather than something that is dependend on external data like DB content.

2f5fd3cf92 test: Correctly decode UTF-8 literal string paths (Ryan Ofsky)
Pull request description:
Call `fs::u8path()` to convert some UTF-8 string literals to paths, instead of relying on the implicit conversion. Fake Macro pointed out in https://github.com/bitcoin/bitcoin/pull/24306#discussion_r818566106 that `fs_tests` are incorrectly decoding some literal UTF-8 paths using the current windows codepage, instead of treating them as UTF-8. This could cause test failures depending what environment windows tests are run under.
The `fs::path` class exists to avoid problems like this, but because it is lenient with `const char*` conversions, under assumption that they are ["safe as long as the literals are ASCII"](727b0cb592/src/fs.h (L39)), bugs like this are still possible.
If we think this is a concern, followup options to try to prevent this bug in the future are:
0. Do nothing
1. Improve the "safe as long as the literals are ASCII" comment. Make it clear that non-ASCII strings are invalid.
2. Drop the implicit `const char*` conversion functions. This would be nice because it would simplifify the `fs::path` class a little, while making it safer. Drawback is that it would require some more verbosity from callers. For example, instead of `GetDataDirNet() / "mempool.dat"` they would have to write `GetDataDirNet() / fs::u8path("mempool.dat")`
3. Keep the implicit `const char*` conversion functions, but make them call `fs::u8path()` internally. Change the "safe as long as the literals are *ASCII*" comment to "safe as long as the literals are *UTF-8*".
I'd be happy with 0, 1, or 2. I'd be a little resistant to 3 even though it was would add more safety, because it would slightly increase complexity, and because I think it would encourage representing paths as strings, when I think there are so many footguns associated with paths as strings, that it's best to convert strings to paths at the earliest point possible, and convert paths to strings at the latest point possible.

a84650ebd5 util: Fix ReadBinaryFile reading beyond maxsize (klementtan)
Pull request description:
Currently `ReadBinaryFile` will read beyond `maxsize` if `maxsize` is not a multiple of `128` (size of buffer)
This is due to `fread` being called with `count = 128` instead of `count = min(128, maxsize - retval.size()` at every iteration
The following unit test will fail:
```cpp
BOOST_AUTO_TEST_CASE(util_ReadWriteFile)
{
fs::path tmpfolder = m_args.GetDataDirBase();
fs::path tmpfile = tmpfolder / "read_binary.dat";
std::string expected_text(300,'c');
{
std::ofstream file{tmpfile};
file << expected_text;
}
{
// read half the contents in file
auto [valid, text] = ReadBinaryFile(tmpfile, expected_text.size() / 2);
BOOST_CHECK_EQUAL(text.size(), 150);
}
}
```
Error:
```
test/util_tests.cpp:2593: error: in "util_tests/util_ReadWriteFile": check text.size() == 150 has failed [256 != 150]

5b1aae12ca qt: Avoid crash on startup if int specified in settings.json (Ryan Ofsky)
84b0973e35 test: Add tests for GetArg methods / settings.json type coercion (Ryan Ofsky)
Pull request description:
Should probably add this change to 23.x as suggested by Luke https://github.com/bitcoin/bitcoin/issues/24457#issuecomment-1059825678. If settings like `prune` are added to `settings.json` in the future, it would be preferable for 23.x releases to respect the setting instead of crash.
---
Fix GUI startup crash reported by Rspigler in https://github.com/bitcoin/bitcoin/issues/24457 that happens if `settings.json` contains an integer value for any of the configuration options which GUI settings can currently clash with (-dbcache, -par, -spendzeroconfchange, -signer, -upnp, -natpmp, -listen, -server, -proxy, -proxy, -onion, -onion, -lang, and -prune).
The fix is a one-line change in `ArgsManager::GetArg`. The rest of the PR just adds a regression test for the GUI and unit tests for ArgsManager::GetArg methods.

691d45fdc8 Add coinstatsindex_unclean_shutdown test (Ryan Ofsky)
eb6cc05da3 index: Commit DB_MUHASH and DB_BEST_BLOCK to disk together (Martin Zumsande)
Pull request description:
Fixes#24076
Coinstatsindex currently writes the MuHash (`DB_MUHASH`) to disk in `CoinStatsIndex::WriteBlock()` and `CoinStatsIndex::ReverseBlock()`, but the best synced block is written in `BaseIndex::Commit()`. These are called at different points in time, both during the ThreadSync phase, and also after the initial sync is finished and validation callbacks (`BlockConnected()` vs `ChainStateFlushed()`) perform the syncing.
As a result, the index DB is temporarily in an inconsistent state, and if bitcoind is terminated uncleanly (so that there is no time to call `Commit()` by receiving an interrupt or by flushing the chainstate) this leads to problems:
On the next startup, `Init()` will read the best block and a MuHash that corresponds to a different (higher) block. Indexing will be picked up at the the best block processing some blocks again, but since MuHash is a rolling hash, it will process some utxos twice and the muhashes for all future blocks will be wrong, as was observed in #24076.
Fix this by always committing `DB_MUHASH` together with `DB_BEST_BLOCK`.
Note that the block data for the index is still written at different times, but this does not corrupt the index - at worst, these entries will be processed another time and overwritten after an unclean shutdown and restart.
