c3e536555aa3a7db773170671da1256a2ace2094 Bugfix: Wallet: Return util::Error rather than non-error nullptr when CreateWallet/LoadWallet/RestoreWallet fail (Luke Dashjr)
335ff98c8a64eda38a2a2334102bd253f108c253 Bugfix: Wallet: Wrap RestoreWallet content in a try block to ensure exceptions become returned errors and incomplete wallet directory is removed (Luke Dashjr)
Pull request description:
Bug 1: `copy_file` can throw exceptions, but `RestoreWallet` is expected to return a nullptr with a populated `errors` parameter. This is fixed by wrapping `copy_file` and `LoadWallet` (for good measure) in a `try` block, and converting any exceptions to the intended return style.
Bug 2: `util::Result` turns what would have been a `false` unique_ptr into a `true` nullptr result, which leads to nullptr dereferences in at least the 3 cases of wallet creation/loading/restoring. This is fixed by keeping the pointer as a plain `std::unique_ptr` until actually returning it (ie, after the nullptr check).

8a105ecd1aeff15f84c3883e2762bf71ad59d920 wallet: Use CalculateMaximumSignedInputSize to indicate solvability (Andrew Chow)
Pull request description:
While running my coin selection simulations, I noticed that towards the end of the simulation, the wallet would become slow to make new transactions. The wallet generally performs much more slowly when there are a large number of transactions and/or a large number of keys. The improvements here are focused on wallets with a large number of transactions as that is what the simulations produce.
Most of the slowdown I observed was due to `DescriptorScriptPubKeyMan::GetSigningProvider` re-deriving keys every time it is called. To avoid this, it will now cache the `SigningProvider` produced so that repeatedly fetching the `SigningProvider` for the same script will not result in the same key being derived over and over. This has a side effect of making the function non-const, which makes a lot of other functions non-const as well. This helps with wallets with lots of address reuse (as my coin selection simulations are), but not if addresses are not reused as keys will end up needing to be derived the first time `GetSigningProvider` is called for a script.
The `GetSigningProvider` problem was also exacerbated by unnecessarily fetching a `SigningProvider` for the same script multiple times. A `SigningProvider` is retrieved to be used inside of `IsSolvable`. A few lines later, we use `GetTxSpendSize` which fetches a `SigningProvider` and then calls `CalculateMaximumSignedInputSize`. We can avoid a second call to `GetSigningProvider` by using `CalculateMaximumSignedInputSize` directly with the `SigningProvider` already retrieved for `IsSolvable`.
There is an additional slowdown where `ProduceSignature` with a dummy signer is called twice for each output. The first time is `IsSolvable` checks that `ProduceSignature` succeeds, thereby informing whether we have solving data. The second is `CalculateMaximumSignedInputSize` which returns -1 if `ProduceSignature` fails, and returns the input size otherwise. We can reduce this to one call of `ProduceSignature` by using `CalculateMaximumSignedInputSize`'s result to set `solvable`.
Lastly, a lot of time is spent looking in `mapWallet` and `mapTxSpends` to determine whether an output is already spent. The performance of these lookups is slightly improved by changing those maps to use `std::unordered_map` and `std::unordered_multimap` respectively.

For some reason, the primary consumer of getWalletTxs requires the
transactions to be in hash order when it is processing them. std::map
will iterate in hash order so the transactions end up in that order when
placed into the vector. To ensure this order when mapWallet is no longer
ordered, the vector is replaced with a set which will maintain the hash
order.

Rename `BResult` class to `util::Result` and update the class interface to be
more compatible with `std::optional` and with a full-featured result class
implemented in https://github.com/bitcoin/bitcoin/pull/25665. Motivation for
this change is to update existing `BResult` usages now so they don't have to
change later when more features are added in #25665.
This change makes the following improvements originally implemented in #25665:
- More explicit API. Drops potentially misleading `BResult` constructor that
treats any bilingual string argument as an error. Adds `util::Error`
constructor so it is never ambiguous when a result is being assigned an error
or non-error value.
- Better type compatibility. Supports `util::Result<bilingual_str>` return
values to hold translated messages which are not errors.
- More standard and consistent API. `util::Result` supports most of the same
operators and methods as `std::optional`. `BResult` had a less familiar
interface with `HasRes`/`GetObj`/`ReleaseObj` methods. The Result/Res/Obj
naming was also not internally consistent.
- Better code organization. Puts `src/util/` code in the `util::` namespace so
naming reflects code organization and it is obvious where the class is coming
from. Drops "B" from name because it is undocumented what it stands for
(bilingual?)
- Has unit tests.

Pull request description:
### Context
The wallet's `m_address_book` field is being accessed directly from several places across the sources.
### Problem
Code structure wise, we shouldn't be accessing it directly. It could end up being modified by mistake (from a place that has nothing to do with the wallet like an RPC command or the GUI) and cause a bigger issue: like an address book entry 'purpose' string change, which if done badly (from 'send' to 'receive'), could end up in a user sharing a "receive" address that he/she doesn't own.
### Solution
Encapsulate `m_address_book` access inside the wallet.
-------------------------------------------------------
Extra Note:
This is the initial step towards decoupling the address book functionality from the wallet's sources. In other words, the creation of the `AddressBookManager` (which will be coming in a follow-up PR).

c7c64db41e1718584aa2f30ff27f60ab0966de62 wallet: cleanup COutput constructor (Andrew Chow)
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.

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.

Pull request description:
There are no code changes, this is just adding `namespace` and `using` declarations and `node::` or `wallet::` qualifiers in some places.
Motivations for this change are:
- To make it easier to see when node and wallet code is being accessed places where it shouldn't be. For example if GUI code is accessing node and wallet internals or if wallet and node code are referencing each other.
- To make source code organization clearer ([#15732](https://github.com/bitcoin/bitcoin/issues/15732)), being able to know that `wallet::` code is in `src/wallet/`, `node::` code is in `src/node/`, `init::` code is in `src/init/`, `util::` code is in `src/util/`, etc.
Reviewing with `git log -p -n1 -U0 --word-diff-regex=.` can be helpful to verify this is only updating declarations, not changing code.

Currently restorewallet() logic is written in the RPC layer
and it can´t be reused by GUI. So it reimplements this in the
wallet and interface sections and then, GUI can access it.

Current CWalletTx state representation makes it possible to set
inconsistent states that won't be handled correctly by wallet sync code
or serialized & deserialized back into the same form.
For example, it is possible to call setConflicted without setting a
conflicting block hash, or setConfirmed with no transaction index. And
it's possible update individual m_confirm and fInMempool data fields
without setting an overall consistent state that can be serialized and
handled correctly.
Fix this without changing behavior by using std::variant, instead of an
enum and collection of fields, to represent sync state, so state
tracking code is safer and more legible.
This is a first step to fixing state tracking bugs
https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Transaction-Conflict-Tracking,
by adding an extra margin of safety that can prevent new bugs from being
introduced as existing bugs are fixed.

There is no change in behavior. This just helps prepare for the
transition from boost::filesystem to std::filesystem by avoiding calls
to methods which will be unsafe after the transaction to std::filesystem
to due lack of a boost::filesystem::path::imbue equivalent and inability
to set a predictable locale.

Followup to commit "MOVEONLY: CWallet transaction code out of
wallet.cpp/.h" that detaches and renames some CWalletTx methods, making
into them into standalone functions or CWallet methods instead.
There are no changes in behavior and no code changes that aren't purely
mechanical. It just gives spend and receive functions more consistent
names and removes the circular dependencies added by the earlier
MOVEONLY commit.
There are also no comment or documentation changes. Removed comments
from transaction.h are just migrated to spend.h, receive.h, and
wallet.h.

Move fillPSBT input-output argument before output-only arguments. This is a
temporary workaround which can go away with improvements to libmultiprocess
code generator. Currently code generator figures out order of input-output
parameters by looking at input list, but it would make more sense for it to
take order from output list, so input-only parameters still have to be first
but there is more flexibility for the other parameters.

Pull request description:
Big picture overview in [this gist](https://gist.github.com/Sjors/29d06728c685e6182828c1ce9b74483d).
This PR adds GUI support for external signers, based on the since merged bitcoin/bitcoin#16546 (RPC).
The UX isn't amazing - especially the blocking calls - but it works.
First we adds a GUI setting for the signer script (e.g. path to HWI):
<img width="625" alt="Schermafbeelding 2019-08-05 om 19 32 59" src="https://user-images.githubusercontent.com/10217/62483415-e1ff1680-b7b7-11e9-97ca-8d2ce54ca1cb.png">
Then we add an external signer checkbox to the wallet creation dialog:
<img width="374" alt="Schermafbeelding 2019-11-07 om 19 17 23" src="https://user-images.githubusercontent.com/10217/68416387-b57ee000-0194-11ea-9730-127d60273008.png">
It's checked by default if HWI detects a device. It also grabs the name. It then creates a fresh wallet and imports the keys.
You can verify an address on the device (blocking...):
<img width="673" alt="Schermafbeelding 2019-08-05 om 19 29 22" src="https://user-images.githubusercontent.com/10217/62483560-43bf8080-b7b8-11e9-9902-8a036116dc4b.png">
Sending, including coin selection, Just Works(tm) as long the device is present.
~External signer support is enabled by default when the GUI is configured and Boost::Process is present.~
External signer support remains disabled by default, see https://github.com/bitcoin/bitcoin/pull/21935.

f5ba424cd44619d9b9be88b8593d69a7ba96db26 wallet: Add IsAddressUsed / SetAddressUsed methods (Russell Yanofsky)
62252c95e5aa55f33a5ef22292d5d8161fcb892a interfaces: Stop exposing wallet destdata to gui (Russell Yanofsky)
985430d9b2e183c1f59a34472e413a8d00a7e6da test: Add gui test for wallet receive requests (Russell Yanofsky)
Pull request description:
Stop giving GUI access to destdata rows in database. Replace with narrow API just for saving and reading receive request information.
This simplifies code and should prevent the GUI from interfering with other destdata like address-used status. It also adds some more GUI test coverage.
There are no changes in behavior.

This commit moves the ExternalSigner class and RPC methods out of the wallet module.
The enumeratesigners RPC can be used without a wallet since #21417.
With additional modifications external signers could be used without a wallet in general, e.g. via signrawtransaction.
The signerdisplayaddress RPC is ranamed to walletdisplayaddress because it requires wallet context.
A future displayaddress RPC call without wallet context could take a descriptor argument.
This commit fixes a rpc_help.py failure when configured with --disable-wallet.
