a5986e82dd2b8f923d60f9e31760ef62b9010105 refactor: Remove CAddressBookData::destdata (Ryan Ofsky)
5938ad0bdb013953861c7cd15a95f00998a06f44 wallet: Add DatabaseBatch::ErasePrefix method (Ryan Ofsky)
Pull request description:
This is cleanup that doesn't change external behavior. Benefits of the cleanup are:
- Removes awkward `StringMap` intermediate representation for wallet address metadata.
- Simplifies `CWallet`, deals with used address and received request serialization in `walletdb.cpp` instead of higher level wallet code
- Adds test coverage and documentation
This PR doesn't change externally observable behavior. Internally, the only change in behavior is that `EraseDestData` deletes rows directly from the database because they are no longer stored in memory. This is more direct and efficient because it uses a single lookup and scan instead of multiple lookups.
Motivation for this cleanup is making changes like #18550, #18192, #13756 easier to reason about and less likely to result in unintended behavior and bugs

be55f545d53d44fdcf2d8ae802e9eae551d120c6 move-only: Extract common/args and common/config.cpp from util/system (TheCharlatan)
Pull request description:
This pull request is part of the `libbitcoinkernel` project https://github.com/bitcoin/bitcoin/issues/24303https://github.com/bitcoin/bitcoin/projects/18 and more specifically its "Step 2: Decouple most non-consensus code from libbitcoinkernel". It is part of a series of patches splitting up the `util/system` files. Its preceding pull request is https://github.com/bitcoin/bitcoin/pull/27254.
The pull request contains an extraction of ArgsManager related functions from util/system into their own common/ file.
The background of this commit is an ongoing effort to decouple the libbitcoinkernel library from the ArgsManager. The ArgsManager belongs into the common library, since the kernel library should not depend on it. See [doc/design/libraries.md](https://github.com/bitcoin/bitcoin/blob/master/doc/design/libraries.md) for more information on this rationale.

Pull request description:
Coming from the following comment https://github.com/bitcoin/bitcoin/pull/25729#discussion_r1029324367.
The reason why we are adding hundreds of UTXO from different sources when the target
amount is covered only by one of them is because only SRD returns a usable result.
Context:
In the test, we create 1515 UTXOs with 0.033 BTC each, and 1 UTXO with 50 BTC. Then
perform Coin Selection to fund 49.5 BTC.
As the selection of the 1515 small UTXOs exceeds the max allowed tx size, the
expectation here is to receive a selection result that only contain the big UTXO.
Which is not happening for the following reason:
Knapsack returns a result that exceeds the max allowed transaction size, when
it should return the closest utxo above the target, so we fallback to SRD who
selects coins randomly up until the target is met. So we end up with a selection
result with lot more coins than what is needed.

dc1cc1c35995dc09085b3d9270c445b7923fdb51 gui: bugfix, getAvailableBalance skips selected coins (furszy)
Pull request description:
Fixes https://github.com/bitcoin-core/gui/issues/688 and https://github.com/bitcoin/bitcoin/issues/26687.
First Issue Description (https://github.com/bitcoin-core/gui/issues/688):
The previous behavior for `getAvailableBalance`, when the coin control had selected coins, was to return the sum of them. Instead, we are currently returning the wallet's available total balance minus the selected coins total amount.
Reason:
Missed to update the `GetAvailableBalance` function to include the coin control selected coins on #25685.
Context:
Since #25685 we skip the selected coins inside `AvailableCoins`, the reason is that there is no need to waste resources walking through the entire wallet's txes map just to get coins that could have gotten by just doing a simple `mapWallet.find`).
Places Where This Generates Issues (only when the user manually select coins via coin control):
1) The GUI balance check prior the transaction creation process.
2) The GUI "useAvailableBalance" functionality.
Note 1:
As the GUI uses a balance cache since https://github.com/bitcoin-core/gui/pull/598, this issue does not affect the regular spending process. Only arises when the user manually select coins.
Note 2:
Added test coverage for the `useAvailableBalance` functionality.
----------------------------------
Second Issue Description (https://github.com/bitcoin/bitcoin/issues/26687):
As we are using a cached balance on `WalletModel::getAvailableBalance`,
the function needs to include the watch-only available balance for wallets
with private keys disabled.

Uses a min-effective-value heap, so we can remove the least valuable input/s
while the selected weight exceeds the maximum allowed weight.
Co-authored-by: Murch <murch@murch.one>
The simplest scenario where this is useful is on the 'check_max_weight' unit test
already:
We create 1515 UTXOs with 0.033 BTC each, and 1 UTXO with 50 BTC. Then perform
Coin Selection.
As the selection of the 1515 small UTXOs exceeds the max allowed tx size, the
expectation here is to receive a selection result that only contain the big
UTXO (which is not happening for the reasons stated below).
As knapsack returns a result that exceeds the max allowed transaction size, we
fallback to SRD, which selects coins randomly up until the target is met. So
we end up with a selection result with lot more coins than what is needed.
The previous behavior for getAvailableBalance when coin control
has selected coins was to return the sum of them. Instead, we
are currently returning the wallet's available total balance minus
the selected coins total amount.
This turns into a GUI-only issue for the "use available balance"
button when the user manually select coins in the send screen.
Reason:
We missed to update the GetAvailableBalance function to include
the coin control selected coins on #25685.
Context:
Since #25685 we skip the selected coins inside `AvailableCoins`,
the reason is that there is no need to traverse the wallet's
txes map just to get coins that can directly be fetched by
their id.
The fs.* files are already part of the libbitcoin_util library. With the
introduction of the fs_helpers.* it makes sense to move fs.* into the
util/ directory as well.
Optimizes coin selection by performing the "group outputs"
procedure only once, outside the "attempt selection" process.
Avoiding the repeated execution of the 'GroupOutputs' operation
that occurs on each coin eligibility filters (up to 8 of them);
then for every coin vector type plus one for all the coins together.
This also let us not perform coin selection over coin eligibility
filtered groups that don't add new elements.
(because, if the previous round failed, and the subsequent one has
the same coins, then this new round will fail again).
The 'GroupOutputs()' function performs the same
calculations for only-positive and mixed groups,
the only difference is that when we look for
only-positive groups, we discard negative utxos.
So, instead of wasting resources calling GroupOutputs()
for positive-only first, then call it again to include
the negative ones in the result, we can execute
GroupOutputs() only once, including in the response
both group types (positive-only and mixed).
The following scenarios are covered:
1) 10 UTXO with the same script:
partial spends is enabled --> outputs must not be grouped.
2) 10 UTXO with the same script:
partial spends disabled --> outputs must be grouped.
3) 20 UTXO, 10 one from scriptA + 10 from scriptB:
a) if partial spends is enabled --> outputs must not be grouped.
b) if partial spends is not enabled --> 2 output groups expected (one per script).
3) Try to add a negative output (value - fee < 0):
a) if "positive_only" is enabled --> negative output must be skipped.
b) if "positive_only" is disabled --> negative output must be added.
4) Try to add a non-eligible UTXO (due not fulfilling the min depth target for
"not mine" UTXOs) --> it must not be added to any group
5) Try to add a non-eligible UTXO (due not fulfilling the min depth target for
"mine" UTXOs) --> it must not be added to any group
6) Surpass the 'OUTPUT_GROUP_MAX_ENTRIES' size and verify that a second partial
group gets created.
And not hide it inside the `OutputGroup::Insert` method.
This method does not return anything if insertion fails.
We can know before calling `Insert` whether the coin
will be accepted or not.

Pull request description:
Structurally, the wallet class shouldn't access the global `ArgsManager` class, its internal behavior shouldn't be coupled to a global command line args parsing object.
So this PR migrates the only two places where we depend on it: (1) the keypool size, and (2) the "-walletnotify" script. And cleans up the, now unneeded, wallet `ArgsManager` ref member.
Extra note:
In the process of removing the args ref member, discovered and fixed files that were invalidly depending on the wallet header including `util/system.h`.

Pull request description:
Instead of having database cursors be tied to a particular `DatabaseBatch` object and requiring its setup and teardown be separate functions in that batch, we can have cursors be separate RAII classes. This makes it easier to create and destroy cursors as well as having cursors that have slightly different behaviors.
Additionally, since reading data from a cursor is a tri-state, this PR changes the return value of the `Next` function (formerly `ReadAtCursor`) to return an Enum rather than the current system of 2 booleans. This greatly simplifies and unifies the code that deals with cursors as now there is no confusion as to what the function returns when there are no records left to be read.

e5e147fe97f706e82bc51358f8bdc355f355be57 wallet: refactor eight consecutive 'AttemptSelection' calls into a loop (furszy)
Pull request description:
Work decoupled from #25806, which cleanup and improves the Coin Selection flow further.
Adding the capability to propagate specific error messages from the Coin Selection process to the user.
Instead of always returning the general "Insufficient funds" message which is not always accurate to what happened internally.
Letting us instruct the user how to proceed under certain circumstances.
The following error messages were added:
1) If the selection result exceeds the maximum transaction weight,
we now will return:
-> "The inputs size exceeds the maximum weight. Please try sending
a smaller amount or manually consolidating your wallet's UTXOs".
2) If the user pre-selected inputs and disallowed the automatic coin
selection process (no other inputs are allowed), we now will
return:
-> "The preselected coins total amount does not cover the transaction
target. Please allow other inputs to be automatically selected or include
more coins manually".
3) The double-counted preset inputs during Coin Selection error will now
throw an "internal bug detected" message instead of crashing the node.
The essence of this work comes from several comments:
1. https://github.com/bitcoin/bitcoin/pull/26560#discussion_r1037395665
2. https://github.com/bitcoin/bitcoin/pull/25729#discussion_r940619491
3. https://github.com/bitcoin/bitcoin/pull/25269#pullrequestreview-1135240825

212ccdf2c2b70d973b18ae78f0158ec5f0c3bbb4 wallet: AvailableCoins, add arg to include/skip locked coins (furszy)
Pull request description:
Negative PR with extended test coverage :).
1) Cleaned duplicated code and added coverage for the 'AvailableCoins' incremental result.
2) The class `AvailableCoinsTestingSetup` inside `availablecoins_tests.cpp` is a plain copy
of `ListCoinsTestingSetup` that is inside `wallet_tests.cpp`.
So, deleted the file and moved the `BasicOutputTypesTest` test case to `wallet_tests.cpp`.
3) Added arg to include/skip locked coins from the `AvailableCoins` result. This is needed for point (1) as otherwise the wallet will spend the coins that we recently created due its closeness to the recipient amount.
Note: this last point comes from #25659 where I'm using the same functionality to clean/speedup another flow as well.

Next()'s result is a tri-state - failed, more to go, complete. Replace
the way that this is returned with an enum with values FAIL, MORE, and
DONE rather than with two booleans.
Instead of having DatabaseBatch deal with opening and closing database
cursors, have a separate RAII class that deals with those.
For now, DatabaseBatch manages DatabaseCursor, but this will change
later.
