Merge #19740: [0.20] wallet: Simplify and fix CWallet::SignTransaction
6a326cf66f04948ffe729e5540a69e159a7840ad tests: Test that a fully signed tx given to signrawtx is unchanged (Andrew Chow)
2d48d7dcfb93eeec36dd6f5cbad289b89ec69324 Simplify and fix CWallet::SignTransaction (Andrew Chow)

Pull request description:

  Backport `CWallet::SignTransaction` from master which is simpler and not broken.

  Previously `CWallet::SignTransaction` would return false for a fully signed transaction. This is a regression and obviously incorrect - a fully signed transaction is always complete. This occurs because `CWallet::SignTransaction` would iterate through each input and skip any further checks if the input was already signed. It would then end up falling through to the `return false` catch-all thus erroneously saying a fully signed transaction is incomplete. The change to attempting to use all `ScriptPubKeyMan`s fixes this problem since the `LegacyScriptPubKeyMan` (the only spkm implemented in 0.20) will verify inputs during its signing attempt and correctly return that it is complete when the inputs verify. Thus a fully signed transaction will be correctly identified as complete, `LegacyScriptPubKeyMan::SignTranaction` will return true, and so `CWallet::Transaction` will return true too.

  Note that this is not a backport of any specific commit. Rather it is the end result of the changes we have made to this function in master.

  Fixes #19737

wallet: Minimal fix to restore conflicted transaction notifications
This fix is a based on the fix by Antoine Riard <ariard@student.42.fr> in
https://github.com/bitcoin/bitcoin/pull/18600.

Unlike that PR, which implements some new behavior, this just restores previous
wallet notification and status behavior for transactions removed from the
mempool because they conflict with transactions in a block. The behavior was
accidentally changed in two `CWallet::BlockConnected` updates:
a31be09bfd77eed497a8e251d31358e16e2f2eb1 and
7e89994133725125dddbfa8d45484e3b9ed51c6e from
https://github.com/bitcoin/bitcoin/pull/16624, causing issue
https://github.com/bitcoin/bitcoin/issues/18325.

The change here could be improved and replaced with a more comprehensive
cleanup, so it includes a detailed comment explaining future considerations.

Fixes #18325

Pull request description:

  In many places, our code assumes that presence in the address book indicates a non-change key, and absence of an entry in mapAddressBook indicates change.

  This no longer holds true after #13756 (first released in 0.19) since it added a "used" DestData populated even for change addresses. Only avoid-reuse wallets should be affected by this issue.

  Thankfully, populating DestData does not write a label to the database, so we can retroactively fix this (so long as the user didn't see the change address and manually assign it a real label).

  Fixing it is accomplished by:

  * Adding a new bool to CAddressBookData to track if the label has ever been assigned, either by loading one from the database, or by assigning one at runtime.
  * `CAddressBookData::IsChange` and `CWallet::FindAddressBookEntry` are new methods to assist in excluding change from code that doesn't expect to see them.
  * For safety in merging, `CAddressBookData::name` has been made read-only (the actual data is stored in `m_label`, a new private member, and can be changed only with `setLabel` which updates the `m_change` flag), and `mapAddressBook` has been renamed to `m_address_book` (to force old code to be rebased to compile).

  A final commit also does some minor optimisation, avoiding redundant lookups in `m_address_book` when we already have a pointer to the `CAddressBookData`.

7b8e15728d1ad058a4b7d7569fd5d5ba6806ca28 rpc: Fix rpcRunLater race in walletpassphrase (João Barbosa)

Pull request description:

  Release locks before calling `rpcRunLater`.

  Quick explanation: `rpcRunLater` leads to `event_free` which calls `event_del` which can wait for the event callback to finish if it's already running and that callback will try to lock wallet mutex - which is already locked in http thread.

  Fixes #14995 , fixes #18482. Best reviewed with whitespace changes hidden.

This no longer holds true (due to bugs) and will shortly be made intentional.

Merge #18338: Fix wallet unload race condition
41b0baf43c243b64b394e774e336475a489cca2b gui: Handle WalletModel::unload asynchronous (João Barbosa)
ab31b9d6fe7b39713682e3f52d11238dbe042c16 Fix wallet unload race condition (Russell Yanofsky)

Pull request description:

  This PR consists in two fixes. The first fixes a concurrency issues with `boost::signals2`. The second fixes a wallet model destruction while it's being used.

  From boost signal documentation at https://www.boost.org/doc/libs/1_72_0/doc/html/signals2/thread-safety.html:

  > When a signal is invoked by calling signal::operator(), the invocation first acquires a lock on the signal's mutex. Then it obtains a handle to the signal's slot list and combiner. Next it releases the signal's mutex, before invoking the combiner to iterate through the slot list.

  This means that `UnregisterValidationInterface` doesn't prevent more calls to that interface. The fix consists in capturing the `shared_ptr<CValidationInterface>` in each internal slot.

  The GUI bug is fixed by using a `Qt::QueuedConnection` in the `WalletModel::unload` connection.

ab31b9d6fe Fix wallet unload race condition
Currently it's possible for ReleaseWallet to delete the CWallet pointer while
it is processing BlockConnected, etc chain notifications.

To fix this, unregister from notifications earlier in UnloadWallet instead of
ReleaseWallet, and use a new RegisterSharedValidationInterface function to
prevent the CValidationInterface shared_ptr from being deleted until the last
notification is actually finished.

1168394d759b13af68acec6d5bfa04aaa24561f8 [wallet] Notify conflicted transactions in TransactionRemovedFromMempool (John Newbery)

Pull request description:

  These boost signals were added in #9371, before we had a `TransactionRemovedFromMempool` method in the validation interface. The `NotifyEntryAdded` callback was used by validation to build a vector of conflicted transactions when connecting a block, which the wallet was notified of in the `BlockConnected` CValidationInterface callback.

  Now that we have a `TransactionRemovedFromMempool` callback, we can fire that signal directly from the mempool for conflicted transactions.

  Note that #9371 was implemented to ensure `-walletnotify` events were fired for these conflicted transaction. We inadvertently stopped sending these notifications in #16624 (Sep 2019 commit 7e89994). We should probably fix that, but in a different PR.

7df0cf719f Replace remaining literals BTC with CURRENCY_UNIT
This replaces one remaining instance of the literal "BTC" string with
the CURRENCY_UNIT constant, as is done in most of the codebase already.

The other remaining instance (which is just part of a log message and thus
not really user-visible) is just removed.

After this change, no instance of literal "BTC" remains anywhere in the
non-Qt and non-test codebase.

1168394d75 [wallet] Notify conflicted transactions in TransactionRemovedFromMempool
The only CValidationInterface client that cares about transactions that
are removed from the mempool because of CONFLICT is the wallet.

Start using the TransactionRemovedFromMempool method to notify about
conflicted transactions instead of using the vtxConflicted vector in
BlockConnected.

2c52b59d0a44a86d94fee4e437978d822862c542 Refactor rawtransaction's SignTransaction into generic SignTransaction function (Andrew Chow)

Pull request description:

  Following #17261, the way to sign transactions, PSBTs, and messages was to use `GetSigningProvider()` and get a `SigningProvider` containing the private keys. However this may not be feasible for future `ScriptPubKeyMan`s, such as for hardware wallets. Instead of exporting a `SigningProvider` containing private keys, we need to pass these things into the `ScriptPubKeyMan` (via `CWallet`) so that they can do whatever is needed internally to sign them. This is largely a refactor as the logic of processing transactions, PSBTs, and messages for is moved into `LegacyScriptPubKeyMan` and `CWallet` instead of being handled by the caller (e.g. `signrawtransaction`).

  To help with this, I've refactored the 3(!) implementations of a `SignTransaction()` function into one generic one. This function will be called by `signrawtransactionwithkey` and `LegacyScriptPubKeyMan::SignTransaction()`. `CWallet::CreateTransaction()` is changed to call `CWallet::SignTransaction()` which in turn, calls `LegacyScriptPubKeyMan::SignTransaction()`. Other `ScriptPubKeyMan`s may implement `SignTransaction()` differently.

  `FillPSBT()` is moved to be a member function of `CWallet` and the `psbtwallet.cpp/h` files removed. It is further split so that `CWallet` handles filling the UTXOs while the `ScriptPubKeyMan` handles adding keys, derivation paths, scripts, and signatures. In the end `LegacyScriptPubKeyMan::FillPSBT` still calls `SignPSBTInput`, but the `SigningProvider` is internal to `LegacyScriptPubKeyMan`. Other `ScriptPubKeyMan`s may do something different.

  A new `SignMessage()` function is added to both `CWallet` and `ScriptPubKeyMan`. Instead of having the caller (i.e. `signmessage` or the sign message dialog) get the private key, hash the message, and sign, `ScriptPubKeyMan` will now handle that (`CWallet` passes through to the `ScriptPubKeyMan`s as it does for many functions). This signing code is thus consolidated into `LegacyScriptPubKeyMan::SignMessage()`, though other `ScriptPubKeyMan`s may implement it differently. Additionally, a `SigningError` enum is introduced for the different errors that we expect to see from `SignMessage()`.

  Lastly, `GetSigningProvider()` is renamed to `GetPublicSigningProvider()`. It will now only provide pubkeys, key origins, and scripts. `LegacySigningProvider` has it's `GetKey` and `HaveKey` functions changed to only return false. Future implementations should return `HidingSigningProvider`s where private keys are hidden.

  Other things like `dumpprivkey` and `dumpwallet` are not changed because they directly need and access the `LegacyScriptPubKeyMan` so are not relevant to future changes.
