6f29409ad1 test: Add a test that creates a wallet with invalid parameters (w0xlt)
0359d9b6a3 Change wallet validation order (w0xlt)
Pull request description:
In the current code, the database is created before the last validation, which checks that passphrase is set and private keys are disabled.
Therefore, if this validation fails, it will result in an empty database and the user will not be able to recreate a wallet with the same name and with the correct parameters.
Behavior on the master branch:
```
$ ./src/bitcoin-cli -regtest -named createwallet wallet_name="invalid_wallet_01" disable_private_keys=true passphrase="passphrase"
error code: -4
error message:
Passphrase provided but private keys are disabled. A passphrase is only used to encrypt private keys, so cannot be used for wallets with private keys disabled.
$ ./src/bitcoin-cli -regtest -named createwallet wallet_name="invalid_wallet_01"
error code: -4
error message:
Wallet file verification failed. Failed to create database path '/home/w/.bitcoin/regtest/wallets/invalid_wallet'. Database already exists.

21520b9551 fuzz: add target for coinselection (Martin Zumsande)
Pull request description:
This adds a fuzz target for the coinselection algorithms by creating random `OutputGroup`s and running all three coin selection algorithms for them.
It does not fuzz higher-level wallet logic for selecting eligible coins (as in `SelectCoins()`), thought it probably would make sense to have a fuzz target for that too.

0c12f0116c wallet: Postpone NotifyWalletLoaded() for encrypted wallets (Hennadii Stepanov)
aeee419c6a wallet, refactor: Add wallet::NotifyWalletLoaded() function (Hennadii Stepanov)
Pull request description:
Fixesbitcoin-core/gui#571.
`CWallet::Create()` notifies about wallet loading too early, that results the notification goes before `DescriptorScriptPubKeyMan`s were created and added to an encrypted wallet.
And `interfaces::Wallet::taprootEnabled()` in ecf692b466/src/qt/receivecoinsdialog.cpp (L100-L102) erroneously returns `false` for just created encrypted descriptor wallets.

Pull request description:
Add sendall RPC née sweep
_Motivation_
Currently, the wallet uses a fSubtractFeeAmount (SFFO) flag on the
recipients objects for all forms of sending calls. According to the
commit discussion, this flag was chiefly introduced to permit sweeping
without manually calculating the fees of transactions. However, the flag
leads to unintuitive behavior and makes it more complicated to test
many wallet RPCs exhaustively. We proposed to introduce a dedicated
`sendall` RPC with the intention to cover this functionality.
Since the proposal, it was discovered in further discussion that our
proposed `sendall` rpc and SFFO have subtly different scopes of
operation.
• sendall:
Use _given UTXOs_ to pay a destination the remainder after fees.
• SFFO:
Use a _given budget_ to pay an address the remainder after fees.
While `sendall` will simplify cases of spending a given set of
UTXOs such as paying the value from one or more specific UTXOs, emptying
a wallet, or burning dust, we realized that there are some cases in
which SFFO is used to pay other parties from a limited budget,
which can often lead to the creation of change outputs. This cannot be
easily replicated using `sendall` as it would require manual
computation of the appropriate change amount.
As such, sendall cannot replace all uses of SFFO, but it still has a
different use case and will aid in simplifying some wallet calls and
numerous wallet tests.
_Sendall call details_
The proposed sendall call builds a transaction from a specific
subset of the wallet's UTXO pool (by default all of them) and assigns
the funds to one or more receivers. Receivers can either be specified
with a given amount or receive an equal share of the remaining
unassigned funds. At least one recipient must be provided without
assigned amount to collect the remainder. The `sendall` call will
never create change. The call has a `send_max` option that changes the
default behavior of spending all UTXOs ("no UTXO left behind"), to
maximizing the output amount of the transaction by skipping uneconomic
UTXOs. The `send_max` option is incompatible with providing a specific
set of inputs.

Edit: Replaced OP with latest commit message to reflect my updated motivation of the proposal.

Pull request description:
Closes#24458 - the wallet always chooses 1 million sats as its change target, making it easier to fingerprint transactions created by the Core wallet. Instead of using a fixed value, choose one randomly each time (within a range). Using 50ksat (around $20) as the lower bound and `min(1 million sat, 2 * average payment value)` as the upper bound.
RFC: If the payment is <25ksat, this doesn't work, so we're using the range (payment amount, 50ksat) instead.

da2bc865d6 [wallet] don't create long chains by default (glozow)
Pull request description:
Default mempool policy doesn't let you have chains longer than 25 transactions. This is locally configurable of course, but it's not really safe to assume that a chain longer than 25 transactions will propagate. Thus, the wallet should probably avoid creating such transactions by default; set `DEFAULT_WALLET_REJECT_LONG_CHAINS` to true.

The final step of send either produces a PSBT or the final transaction.
We extract these steps to a new helper function `FinishTransaction()` to
reuse them in `sendall`.

Pull request description:
While working on coin selection code, it occurred to me that `CInputCoin` is really a subset of `COutput` and the conversion of a `COutput` to a `CInputCoin` does not appear to be all that useful. So this PR adds fields that are present in `CInputCoin` to `COutput` and replaces the usage of `CInputCoin` with `COutput`.
`COutput` is also moved to coinselection.h. As part of this move, the usage of `CWalletTx` is removed from `COutput`. It is instead replaced by storing a `COutPoint` and the `CTxOut` rather than the entire `CWalletTx` as coin selection does not really need the full `CWalletTx`. The `CWalletTx` was only used for figuring out whether the transaction containing the output was from the current wallet, and for the transaction's time. These are now parameters to `COutput`'s constructor.

39b1763730 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.

These operators are used only by the tests in std::mismatch. As
std::mismatch can take a binary predicate, we can use a lambda that
achieves the same instead.
Instead of having a pointer to the CWalletTx in COutput, we can just
store the COutPoint and the CTxOut as those are the only things we need
from the CWalletTx. Other things CWalletTx used to provide were time and
fIsFromMe but these are also being stored by COutput.

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).

Instead of determining whether the containing transaction is from the
wallet dynamically as needed, just pass it in to COutput and store it.
The transaction ownership isn't going to change.
