82caa8193a wallet: migration, fix watch-only and solvables wallets names
Because the default wallet has no name, the watch-only and solvables
wallets created during migration end up having no name either.

This fixes it by applying the same prefix name we use for the backup
file for an unnamed default wallet.

Before: watch-only wallet named "_watchonly"
After:  watch-only wallet named "default_wallet_watchonly"

d70b159c42 wallet: improve post-migration logging
Right now, after migration the last message users see is "migration completed",
but the migration isn't actually finished yet. We still need to load the new wallets
to ensure consistency, and if that fails, the migration will be rolled back. This
can be confusing for users.

This change logs the post-migration loading step and if a wallet fails to load and
the migration will be rolled back.

f4c7e28e80 wallet: fix unnamed wallet migration failure
When migrating any legacy unnamed wallet, a failed migration would
cause the cleanup logic to remove its parent directory. Since this
type of legacy wallet lives directly in the main '/wallets/' folder,
this resulted in unintentionally erasing all wallets, including the
backup file.

To be fully safe, we will no longer call `fs::remove_all`. Instead,
we only erase the individual db files we have created, leaving
everything else intact. The created wallets parent directories are
erased only if they are empty.
As part of this last change, `RestoreWallet` was modified to allow
an existing directory as the destination, since we no longer remove
the original wallet directory (we only remove the files we created
inside it). This also fixes the restore of top-level default wallets
during failures, which were failing due to the directory existence
check that always returns true for the /wallets/ directory.

This bug started after:
f6ee59b6e2
Previously, the `fs::copy_file` call was failing for top-level wallets,
which prevented the `fs::remove_all` call from being reached.

4ed0693a3f wallet: RestoreWallet failure, erase only what was created
Track what RestoreWallet creates so only those files and directories
are removed during a failure and nothing else. Preexisting paths
must be left untouched.

Note:
Using fs::remove_all() instead of fs::remove() in RestoreWallet does
not cause any problems currently, but the change is necessary for the
next commit which extends RestoreWallet to work with existing directories,
which may contain files that must not be deleted.

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.

4dfe383912 refactor: Convert ChainstateRole enum to struct

* `mapInfo` is instance of `std::unordered_map` and can only contain 0 or 1 value for a given key;
* similarly, `g_enabled_filter_types` and `setClientRules` are both `std::set` instances;
* lastly, while `mapTxSpends` is `std::unordered_multimap` that could potentially hold multiple values, having a size less than 1 means that the value is missing.

`QMap<WalletModel*, WalletView*> mapWalletViews` values were also migrated manually.

07a926474b node: change a tx-relay on/off flag to enum
Previously the `bool relay` argument to `BroadcastTransaction()`
designated:

```
relay=true: add to the mempool and broadcast to all peers
relay=false: add to the mempool
```

Change this to an `enum`, so it is more readable and easier to extend
with a 3rd option. Consider these example call sites:

```cpp
Paint(true);
// Or
Paint(/*is_red=*/true);
```

vs

```cpp
Paint(RED);
```

The idea for putting `TxBroadcastMethod` into `node/types.h` by Ryan.

88b0647f02 wallet: Always write last hardened cache flag in migrated wallets (Ava Chow)
8a08eef645 tests: Check that the last hardened cache upgrade occurs (Ava Chow)

Pull request description:

  #32597 set the descriptor cache upgraded flag for newly created wallets, but migrated wallets still did not have the flag set when they are migrated. For consistency, and to avoid an unnecessary upgrade, we should be setting this flag for migrated wallets.

  The flag would end up being set anyways at the end of migration when the wallet is reloaded as it would perform the automatic upgrade at that time. However, this is unnecessary and we should just set it from the get go.

  This PR also adds a couple tests to verify that the flag is being set, and that the upgrade is being performed.

e76c2f7a41 test: Test wallet 'from me' status change (Ava Chow)

Pull request description:

  One of the ways that the wallet would determine if a transaction was sent from the wallet was by checking if the total amount being spent by a transaction from outputs known to the wallet was greater than 0. This has worked fine until recently since there was no reason for 0-value outputs to be created. However, with ephemeral dust and P2A, it is possible to create standard 0-value outputs, and the wallet was not correctly identifying the spends of such outputs. This PR updates `IsFromMe` to only check whether the wallet knows any of the inputs, rather than checking the debit amount of a transaction.

  Additionally, a new functional test is added to test for this case, as well as a few other anchor output related scenarios. This also revealed a bug in `sendall` which would cause an assertion error when trying to spend all of the outputs in a wallet that has anchor outputs.

  Fixes #33265

30c6f64eed test: Remove unnecessary LoadWallet() calls (pablomartin4btc)

Pull request description:

  Remove dead code due to legacy wallet removal.

  Leftovers from previous #32481.

  ---

  **Note**:

  While attempting to remove the legacy check in `CWallet::UpgradeDescriptorCache()` (which is called from `DBErrors WalletBatch::LoadWallet(CWallet* pwallet))`, I once again ran into the fact that `LoadWallet()` is used in two distinct scenarios — something I was already aware of:
  - Wallet creation – the upgrade is ignored here because no wallet flags are yet set; attempting to set a flag (ie `WALLET_FLAG_LAST_HARDENED_XPUB_CACHED` at the end of the upgrade function, if the legacy check is removed) would produce a failure (`DBErrors CWallet::LoadWallet()` -> `Assert(m_wallet_flags == 0)`).
  - Wallet loading – the upgrade proceeds correctly and the flag `WALLET_FLAG_LAST_HARDENED_XPUB_CACHED` is set.

  While revisiting this, I also noticed that some `LoadWallet()` calls in the wallet tests are unnecessary and I've removed them in the first commit.

  The following change in `UpgradeDescriptorCache()` could be done in PR #32636 as part of the separation between wallet loading and creation responsibilities.

  ```diff --git a/src/wallet/wallet.cpp b/src/wallet/wallet.cpp

   void CWallet::UpgradeDescriptorCache()
   {
  +    // Only descriptor wallets can upgrade descriptor cache
  +    Assert(IsWalletFlagSet(WALLET_FLAG_DESCRIPTORS));
  +
  -    if (!IsWalletFlagSet(WALLET_FLAG_DESCRIPTORS) || IsLocked() || IsWalletFlagSet(WALLET_FLAG_LAST_HARDENED_XPUB_CACHED)) {
  +    if (IsLocked() || IsWalletFlagSet(WALLET_FLAG_LAST_HARDENED_XPUB_CACHED)) {
           return;
       }
  ```

39a7dbdd27 wallet: Determine IsFromMe by checking for TXOs of inputs
Instead of checking whether the total amount of inputs known by the
wallet is greater than 0, we should be checking for whether the input is
known by the wallet. This enables us to determine whether a transaction
spends an of output with an amount of 0, which is necessary for marking
0-value dust outputs as spent.

  This PR Implements the following:
  - If creating a v3 transaction, `AvailableCoins` doesn't return unconfirmed v2 utxos (and vice versa)
  - `AvailableCoins` doesn't return an unconfirmed v3 utxo if its transaction already has a child
  - If a v3 transaction is kicked out of the mempool by a sibling, mark the sibling as a mempool conflict
  - Throw an error if pre-selected inputs are of the wrong transaction version
  - Allow setting version to 3 manually in `createrawtransaction` (uses commits from #31936)
  - Limits a v3 transaction weight in coin selection

  Closes #31348

  To-Do:
  - [x] Test a v3 sibling conflict kicking out one of our transactions from the mempool
  - [x] Implement separate size limit for TRUC children
  - [x] Test that we can't fund a v2 transaction when everything is v3 unconfirmed
  - [x] Test a v3 sibling conflict being removed from the mempool
  - [x] Test limiting v3 transaction weight in coin selection
  - [x] Simplify tests
  - [x] Add documentation
  - [x] Test that user-input max weight is not overwritten by truc max weight
  - [x] Test v3 in RPCs other than `createrawtransaction`

2b00030af8 interfaces, chain, refactor: Remove inaccurate getActiveChainLocator
The getActiveChainLocator method name was misleading, and its functionality
duplicated `Chain::findBlock`. This commit removes the method and replaces
all its usages with direct `Chain::findBlock` calls.

Additionally, the comment of getActiveChainLocator has been outdated since
commit ed47094 from #25717.

Finally, in CWallet::ScanForWalletTransactions, the findBlock calls are now
unified into a single call at the start of the function.

01737883b3 wallet: Translate [default wallet] string in progress messages (Ryan Ofsky)

Pull request description:

  Noticed while reviewing https://github.com/bitcoin/bitcoin/pull/31287#discussion_r1843809721 that the [default wallet] part of progress messages remains untranslated while the rest of the string is translated.

  Fix this in all places where `CWallet::ShowProgress` (which has a cancel button) and `Chain::showProgress` (which doesn't have a cancel button) are called by making "default wallet" into a translated string.

e22c3599c6 test: wallet: Check direct file backup name. (David Gumberg)

Pull request description:

  Support for wallets outside of the default wallet directory was added in #11687, and these external wallets can be specified with paths relative to the wallet directory, e.g.  `bitcoin-cli loadwallet ../../mywallet`. In the RPC commands, there is no distinction between a wallet's 'name' and a wallet's 'path'. This PR fixes an issue with wallet backup during migration where the wallet's 'name-path' is used in the backup filename. This goes south when that filename is appended to the directory where we want to put the file and the wallet's 'name' actually gets treated as a path:

  ```cpp
      fs::path backup_filename = fs::PathFromString(strprintf("%s_%d.legacy.bak", (wallet_name.empty() ? "default_wallet" : wallet_name), GetTime()));
      fs::path backup_path = this_wallet_dir / backup_filename;
  ```

  Attempting to migrate a wallet with the 'name' `../../../mywallet` results in a backup being placed in `datadir/wallets/../../../mywallet/../../../mywallet_1744683963.legacy.bak`.

  If permissions don't exist to write to that folder, migration can fail.

  The solution implemented here is to put backup files in the top-level of the node's `walletdir` directory, using the folder name (and in some rare cases the file name)  of the wallet to name the backup file:

  9fa5480fc4/src/wallet/wallet.cpp (L4254-L4268)

  ##### Steps to reproduce on master
  Build and run `bitcoind` with legacy wallet creation enabled:
  ```bash
  $ cmake -B build -DWITH_BDB=ON && cmake --build build -j $(nproc)
  $ ./build/bin/bitcoind -regtest -deprecatedrpc=create_bdb
  ```

  Create a wallet with some relative path specifiers (exercise caution with where this file may be written)

  ```bash
  $ ./build/bin/bitcoin-cli -regtest -named createwallet wallet_name="../../../myrelativewallet" descriptors=false
  ```

  Try to migrate the wallet:
  ```bash
  $ ./build/bin/bitcoin-cli -regtest -named migratewallet wallet_name="../../../myrelativewallet"
  ```

  You will see a message in `debug.log` about trying to backup a file somewhere like: `/home/user/.bitcoin/regtest/wallets/../../../myrelativewallet/../../../myrelativewallet_1744686627.legacy.bak` and migration might fail because `bitcoind` doesn't have permissions to write the backup file.

6135e0553e wallet, rpc: Move (Un)LockCoin WalletBatch creation out of RPC (Ava Chow)

Pull request description:

  If the locked coin needs to be persisted to the wallet database, insteead of having the RPC figure out when to create a WalletBatch and having LockCoin's behavior depend on it, have LockCoin take whether to persist as a parameter so it makes the batch.

  Since unlocking a persisted locked coin requires a database write as well, we need to track whether the locked coin was persisted to the wallet database so that it can erase the locked coin when necessary.

  Keeping track of whether a locked coin was persisted is also useful information for future PRs.

  This can be tested by migrated a legacy wallet from another network (e.g. trying to migrate a testnet wallet on mainnet). The fixed behavior is return an error and restore the backup.
