Merge #15235: Do not import private keys to wallets with private keys disabled
e6c58d3b01 Do not import private keys to wallets with private keys disabled (Andrew Chow)
b5c5021b64 Refactor importwallet to extract data from the file and then import (Andrew Chow)
1f77f6754c tests: unify RPC argument to cli argument conversion and handle dicts and lists (Andrew Chow)

Pull request description:

  Fixes a bug where private keys could be imported to wallets with private keys disabled. Now every RPC which can import private keys checks for whether the wallet has private keys are disabled and errors if it is. Also added an belt-and-suspenders check to `AddKeyPubkeyWithDB` to have it assert that the wallet has private keys enabled.

  - https://github.com/bitcoin/bitcoin/pull/14711#pullrequestreview-193702611 by @ryanofsky

  This gcc [issue](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47679) has been known since version 4.6.0 and last updated in 2017.
  From the boost [docs](https://www.boost.org/doc/libs/1_69_0/libs/optional/doc/html/boost_optional/quick_start/optional_automatic_variables.html):
  > The default constructor of `optional` creates an _uninitialized_ `optional` object.

  Also: [False positive with -Wmaybe-uninitialized](https://www.boost.org/doc/libs/1_69_0/libs/optional/doc/html/boost_optional/tutorial/gotchas/false_positive_with__wmaybe_uninitialized.html) ([pointed out](https://github.com/bitcoin/bitcoin/pull/15292#issuecomment-459063170) by @Empact)

Merge #15279: wallet: Clarify rescanblockchain doc
fa5e6ef55c wallet: Fixup rescanblockchain result doc (MarcoFalke)

Pull request description:

  This was probably accidentally added to the wrong line when addressing the feedback here: https://github.com/bitcoin/bitcoin/pull/7061#discussion_r142199778

  I already added the default values in #14877, but it could be clarified more that this really has no specific block height as default value, since the tip can change during a rescan.

Merge #14711: Remove uses of chainActive and mapBlockIndex in wallet code
44de1561a Remove remaining chainActive references from CWallet (Russell Yanofsky)
db21f0264 Convert CWallet::ScanForWalletTransactions and SyncTransaction to the new Chain apis (Russell Yanofsky)

d93c4c1d6 Add time methods to the Chain interface (Russell Yanofsky)
700c42b85 Add height, depth, and hash methods to the Chain interface (Russell Yanofsky)

Pull request description:

  This change removes uses of `chainActive` and `mapBlockIndex` globals in wallet code. It is a refactoring change which does not affect external behavior.

  This is the next step in the larger #10973 refactoring change, which removes all other accesses to node global variables from wallet code. Doing this is useful to provide a better defined interface between the wallet and node, and necessary to allow wallet and node code to run in separate processes in #10102.

Merge #14906: refactor: Make explicit CMutableTransaction -> CTransaction conversion.
b301950df3  Made expicit constructor CTransaction(const CMutableTransaction &tx). (lucash-dev)
faf29dd019  Minimal changes to comply with explicit CMutableTransaction -> CTranaction conversion. (lucash-dev)

Pull request description:

  This PR is re-submission of #14156, which was automatically closed by github (glitch?)

  Original description:

  This PR makes explicit the now implicit conversion constructor `CTransaction(const CMutableTransaction&)` in `transaction.h`.
  Minimal changes were made elsewhere to make the code compilable. I'll follow up with other PRs to address individually refactoring functions that should have a `CMutableTransaction` version, or where a `CTransaction` should be reused.

  The rationale for this change is:

   - Conversion constructors should not be explicit unless there's a strong reason for it (in the opinion of, for example, https://google.github.io/styleguide/cppguide.html, and https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Ro-conversion. Let me know your take on this).
   - This particular conversion is very costly -- it implies a serialization plus hash of the transaction.
   - Even though `CTransaction` and `CMutableTransaction` represent the same data, they have very different use cases and performance properties.
   - Making it explicit allows for easier reasoning of performance trade-offs.
   - There has been previous performance issues caused by unneeded use of this implicit conversion.
   - This PR creates a map for places to look for possible refactoring and performance gains (this benefit still holds if the PR is not merged).

Merge #14941: rpc: Make unloadwallet wait for complete wallet unload
645e905c32 doc: Add release notes for unloadwallet change to synchronous call (João Barbosa)
c37851de57 rpc: Make unloadwallet wait for complete wallet unload (João Barbosa)

Pull request description:

  Currently the `unloadwallet` RPC is asynchronous, it only signals the intent to unload the wallet and then returns the response to the client. The actual unload can happen later and the client has no way to be notified of that.

  This PR makes the `unloadwallet` RPC synchronous, meaning that it blocks until the wallet is fully unloaded.

  Replaces #14919, fixes #14917.

Merge #14653: rpcwallet: Add missing transaction categories to rpc helptexts
f3f6dde56e Test coinbase category in wallet rpcs (andrewtoth)
e982f0b682 Add all category options to wallet rpc help (andrewtoth)

Pull request description:

  The current helptext for `listtransactions`, `listsinceblock` and `gettransaction` only list two of the five possible options for `category`. This incorrectly implies that these are the only two options, and can cause problems if the other three options aren't accounted for. Also, some of the documentation is incorrect when specifying which options are returned for which categories.

  This PR updates the helptext for these RPCs and adds a functional regression test for the cases when the other three categories are returned.

This commit makes the minimal changes necessary to fix compilation once CTransaction(const CMutableTransaction &tx) is made explicit. In each case an explicit call `CTransaction(...)` was added. Shouldn't affect behaviour or performance.

Pull request description:

  This PR adds functionality to convert a script to a descriptor, given a `SigningProvider` with the relevant information about public keys and redeemscripts/witnessscripts.

  The feature is exposed in `listunspent`, `getaddressinfo`, and `scantxoutset` whenever these calls are applied to solvable outputs/addresses.

  This is not very useful on its own, though when we add RPCs to import descriptors, or sign PSBTs using descriptors, these strings become a compact and standalone way of conveying everything necessary to sign an output (excluding private keys).

  Unit tests and rudimentary RPC tests are included (more relevant tests can be added once RPCs support descriptors).

  Fixes #14503.

Pull request description:

  As discussed in the comments on #14473, I think that bug was caused primarily by failure to adhere to the invariant that a PSBTInput always has exactly one of the two utxo fields present -- an invariant that is already enforced by PSBTInput::IsSane, but which we were temporarily suspending during signing.

  This refactor repairs the invariant, also fixing the bug. It also simplifies some other code, and removes redundant parameters from some related functions.

  fixes #14473

01a4c095c8 wallet: Add WalletLocation utility class (João Barbosa)

Pull request description:

  Advantages of this change:
   - avoid resolving wallet absolute path and name repetitively and in multiple places;
   - avoid calling `GetWalletDir` in multiple places;
   - extract these details from the actual wallet implementation.

  The `WalletLocation` class can be a way to represent a wallet not yet loaded that exists in the wallet directory.

Merge #14410: rpcwallet: 'ischange' field for 'getaddressinfo' RPC
14a06525b2 tests: add test for 'getaddressinfo' RPC result 'ischange' field (whythat)
93d1aa9abc rpcwallet: add 'ischange' field to 'getaddressinfo' response (whythat)

Pull request description:

  Implementation of proposal in #14396.

  This introduces `CWallet::IsChange(CScript&)` method and replaces original `CWallet::IsChange(CTxOut&)` method with overloaded version that delegates to the new method with *txout*'s `scriptPubKey`. In this way `TODO` note from the original method can still be addressed in a single place.

565500508a Refactor PSBTInput signing to enforce invariant
Refactor the process of PSBTInput signing to enforce the invariant that
a PSBTInput always has _either_ a witness_utxo or a non_witness_utxo,
never both.

This simplifies the logic of SignPSBTInput slightly, since it no longer
has to deal with the "both" case. When calling it, we now give it, in
order of preference: (1) whichever of the utxo fields was already
present in the PSBT we received, or (2) if neither, the
non_witness_utxo field, which is just a copy of the input transaction,
which we get from the wallet.

SignPSBTInput no longer has to remove one of the two fields; instead, it
will check if we have a witness signature, and if so, it will replace
the non_witness_utxo with the witness_utxo (which is smaller, as it is
just a copy of the output being spent.)

Add PSBTInput::IsSane checks in two more places, which checks for
both utxo fields being present; we will now give an RPC error early on
if we are supplied such a malformed PSBT to fill in.

Also add a check to FillPSBT, to avoid touching any input that is
already signed. (This is now redundant, since we should no longer
potentially harm an already-signed input, but it's harmless.)

fixes #14473

0f5bda2bd9 Simplify arguments to SignPSBTInput
Remove redundant arguments to SignPSBTInput -- since it needs several
bits of the PartiallySignedTransaction, pass in a reference instead of
doing it piecemeal. This saves us having to pass in both a PSBTInput and
its index, as well as having to pass in the CTransaction. Also avoid
redundantly passing the sighash_type, which is contained in the
PSBTInput already.
