39b1763730177cd7d6a32fd9321da640b0d65e0e Replace use of `ArgsManager` with `DatabaseOptions` (Kiminuo)
Pull request description:
Contributes to #21005.
The goal of this PR is to remove `gArgs` from database classes (i.e. `bdb.h` and `sqlite.h`) so that they can be tested without relying on `gArgs` in tests.
Notes:
* My goal is to enable unit-testing without relying on `gArgs` as much as possible. Global variables are hard to reason about which in turn makes it slightly harder to contribute to this codebase. When the compiler does the heavy lifting for us and allows us only to construct an object (or call a method) with valid parameters, we may also save some time in code reviews. The cost for this is passing an argument which is not for free but the cost is very miniscule compared to benefits, I think.
* GUI code is an exception because it seems fine to have `gArgs` there so I don't plan to make changes in `src/qt` folder, for example.
* My approach to removal of `gArgs` uses is moving from lower levels to upper ones and pass `ArgsManager` as an argument as needed. The approach is very similar to what #20158.

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).
On my machine (median of 5 trials):

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).

Pull request description:
#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.
8ea6167099ddfe9a42464c3c8ae2acd895329d4f 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.

Pull request description:
Currently inactive HD chains are only derived from at the time a key in that chain is found to have been used. However, at that time, the wallet may not be able to derive keys (e.g. it is locked). Currently we would just move on and not derive any new keys, however this could result in missing funds.
This PR resolves this problem by adding memory only variables to `CHDChain` which track the highest known index. `TopUp` is modified to always try to top up the inactive HD chains, and this process will use the new variables to determine how much to top up. In this way, after an encrypted wallet is unlocked, the inactive HD chains will be topped up and hopefully funds will not be missed.
Note that because these variables are not persisted to disk (because `CHDChain`s for inactive HD chains are not written to disk), if an encrypted wallet is not unlocked in the same session as a key from an inactive chain is found to be used, then it will not be topped up later unless more keys are found.
Additionally, wallets which do not have upgraded key metadata will not derive any keys from inactive HD chains. This is resolved by using the derivation path string in `CKeyMetadata.hdKeypath` to determine what indexes to derive.

Instead of having CBlockIndex's live on the heap, which requires manual
memory management, have them be owned by m_block_index. This means that
they will live and die with BlockManager.
A change to BlockManager::LookupBlockIndex:
- Previously, it was a const member function returning a non-const CBlockIndex*
- Now, there's are const and non-const versions of
BlockManager::LookupBlockIndex returning a CBlockIndex with the same
const-ness as the member function:
(e.g. const CBlockIndex* LookupBlockIndex(...) const)
See next commit for some weirdness that this eliminates.
The range based for-loops are modernize (using auto + destructuring) in
a future commit.

This should also fix an init error if a -walletdir with a trailing slash
is used on windows. This appears to be a real error and regression
introduced with #20744.
On windows (or at least wine), fs calls that actuallly access the
filesystem like fs::equivalent or fs::exists seem to treat directory
paths with trailing slashes as not existing, so it's necessary to
normalize these paths before using them. This change passes canonical
paths to fs calls validating the -walletdir path to fix this.
Warning: Replacing fs::system_complete calls with fs::absolute calls
in this commit may cause minor changes in behaviour because fs::absolute
no longer strips trailing slashes; however these changes are believed to
be safe.

Extracting the constant makes it possible to attach documentation to it.
Also, rework the docs for the other "sequence constants".

fa65bbf217b725ada35107b4ad646d250228355c span: Add BytePtr helper (MarcoFalke)
Pull request description:
This changes the serialize code (`.read()` and `.write()` functions) to take a `Span` instead of a pointer and size. This is a breaking change for the serialize interface, so at no additional cost we can also switch to `std::byte` (instead of using `char`).
The benefits of using `Span`:
* Less verbose and less fragile code when passing an already existing `Span`(-like) object to or from serialization
The benefits of using `std::byte`:
* `std::byte` can't accidentally be mistaken for an integer
The goal here is to only change serialize to use spans of `std::byte`. If needed, `AsBytes`, `MakeUCharSpan`, ... can be used (temporarily) to pass spans of the right type.

Pull request description:
Issues:
- `CBlockIndex` member functions `GetBlockPos()`, `GetUndoPos()`, `IsAssumedValid()`, `RaiseValidity()`, and `IsValid()` and block storage functions `WriteUndoDataForBlock()` and `IsBlockPruned()` are missing thread safety lock annotations to help ensure that they are called with mutex cs_main to avoid bugs like #22895. Doing this also enables the next step:
- `CBlockIndex::nStatus` may be racy, i.e. potentially accessed by multiple threads, see #17161. A solution is to guard it by cs_main, along with fellow data members `nFile`, `nDataPos` and `nUndoPos`.
This pull:
- adds thread safety lock annotations for the functions listed above
- guards `CBlockIndex::nStatus`, `nFile`, `nDataPos` and `nUndoPos` by cs_main
How to review and test:
- debug build with clang and verify there are no `-Wthread-safety-analysis` warnings
- review the code to verify each annotation or lock is necessary and sensible, or if any are missing
- look for whether taking a lock can be replaced by a lock annotation instead
- for more information about Clang thread safety analysis, see

dddd05e7a3389fcbd90bb4acdfe1f59945d9f381 qt: Treat unconfirmed txs as unconfirmed (MarcoFalke)
Pull request description:
The wallet has several issues:
## Unconfirmed txs in the GUI
The GUI clumsily attempts to guess if unconfirmed txs are locked until a future time. This is currently based on the locktime only, not nSequence, thus wrong. Fix this by removing the clumsy code and treat all unconfirmed txs as unconfirmed. The GUI already prints whether a tx is in the mempool, in which case the user knows that the tx wasn't locked until a future time. If the tx is not in the mempool, it might be better to report the exact reject reason from the mempool instead of using incorrect heuristics.
## Confirmed txs in the wallet
The wallet drops coins that it incorrectly assumes to be locked until a future time, even if they are already confirmed in the chain. This is because the wallet is using the wrong time (adjusted network time) instead of MTP, due to the `-1` default argument of `CheckFinalTx`.
The issues are fixed in separate commits and there is even a test.
