Pull request description:

  Work starter to remove Chain::Lock interface by adding m_last_block_processed_height in CWallet and m_block_height in CMerkleTx to avoid GetDepthInMainChain having to keep a lock . Once this one done, it should ease work to wipe out more cs_main locks from wallet code.

  I think it's ready for a first round of review before to get further.

  - `BlockUntilSyncedToCurrent` : restrain isPotentialTip to isTip because we want to be sure that wallet see BlockDisconnected callbacks if its height differs from the Chain one. It means during a reorg, an RPC could return before the BlockDisconnected callback had been triggered. This could cause a tx that had been included in the disconnected block to be displayed as confirmed, for example.

  ~~- `AbandonTransaction` : in case of conflicted tx (nIndex = -1), we set its m_block_height to the one of conflicting blocks, but if this height is superior to CWallet::m_last_block_processed_height, that means tx isn't conflicted anymore so we return 0 as tx is again unconfirmed~~ After #16624, we instead rely on Confirmation.

  ~~- `AddToWalletIfInvolvingMe`: in case of block disconnected, transactions are added to mempool again, so we need to replace old txn in `mapWallet` with a height set to zero so we remove check on block_hash.IsNull~~ Already done in #16624

f77b1de16f Only return early from BlockUntilSyncedToCurrentChain if current tip
is exact match

In the next commit, we start using BlockConnected/BlockDisconnected
callbacks to establish tx depth, rather than querying the chain
directly.

Currently, BlockUntilSyncedToCurrentChain will return early if
the best block processed by the wallet is a descendant of the node'tip.
That means that in the case of a re-org, it won't wait for the
BlockDisconnected callbacks that have been enqueued during the re-org
but have not yet been triggered in the wallet.

Change BlockUntilSyncedToCurrentChain to only return early if the
wallet's m_last_block_processed matches the tip exactly. This ensures
that there are no BlockDisconnected or BlockConnected callbacks
in-flight.

5971d3848e Add block_height field in struct Confirmation
At wallet loading, we rely on chain state querying to retrieve
height of txn, to do so we ensure that lock order is respected
between cs_main and cs_wallet.

If wallet loaded is the wallet-tool one, all wallet txn will
show up with a height of zero. It doesn't matter as confirmation
height is not used by wallet-tool.

Reorder arguments and document Confirmation calls to avoid
ambiguity.

Fixes nits left from #16624

dce032ce29 Make IsTrusted scan parents recursively (Jeremy Rubin)

Pull request description:

  This slightly modifies the behavior of IsTrusted to recursively check the parents of a transaction. Otherwise, it's possible that a parent is not IsTrusted but a child is. If a parent is not trusted, then a child should not be either.

  This recursive scan can be a little expensive, so ~it might be beneficial to have a way of caching IsTrusted state, but this is a little complex because various conditions can change between calls to IsTrusted (e.g., re-org).~ I added a cache which works per call/across calls, but does not store the results semi-permanently. Which reduces DoS risk of this change. There is no risk of untrusted parents causing a resource exploitation, as we immediately return once that is detected.

  This is a change that came up as a bug-fix esque change while working on OP_SECURETHEBAG. You can see the branch where this change is important here: https://github.com/bitcoin/bitcoin/compare/master...JeremyRubin:stb-with-rpc?expand=1. Essentially, without this change, we can be tricked into accepting an OP_SECURETHEBAG output because we don't properly check the parents. As this was a change which, on its own, was not dependent on OP_SECURETHEBAG, I broke it out as I felt the change stands on its own by fixing a long standing wallet bug.

  The test wallet_balance.py has been corrected to meet the new behavior. The below comment, reproduced, explains what the issue is and the edge cases that can arise before this change.

          # Before `test_balance()`, we have had two nodes with a balance of 50
          # each and then we:
          #
          # 1) Sent 40 from node A to node B with fee 0.01
          # 2) Sent 60 from node B to node A with fee 0.01
          #
          # Then we check the balances:
          #
          # 1) As is
          # 2) With transaction 2 from above with 2x the fee
          #
          # Prior to #16766, in this situation, the node would immediately report
          # a balance of 30 on node B as unconfirmed and trusted.
          #
          # After #16766, we show that balance as unconfirmed.
          #
          # The balance is indeed "trusted" and "confirmed" insofar as removing
          # the mempool transactions would return at least that much money. But
          # the algorithm after #16766 marks it as unconfirmed because the 'taint'
          # tracking of transaction trust for summing balances doesn't consider
          # which inputs belong to a user. In this case, the change output in
          # question could be "destroyed" by replace the 1st transaction above.
          #
          # The post #16766 behavior is correct; we shouldn't be treating those
          # funds as confirmed. If you want to rely on that specific UTXO existing
          # which has given you that balance, you cannot, as a third party
          # spending the other input would destroy that unconfirmed.
          #
          # For example, if the test transactions were:
          #
          # 1) Sent 40 from node A to node B with fee 0.01
          # 2) Sent 10 from node B to node A with fee 0.01
          #
          # Then our node would report a confirmed balance of 40 + 50 - 10 = 80
          # BTC, which is more than would be available if transaction 1 were
          # replaced.

  The release notes have been updated to note the new behavior.

f201ba59ff Refactor: Split up CWallet and LegacyScriptPubKeyMan and classes
This moves CWallet members and methods dealing with keys to a new
LegacyScriptPubKeyMan class, and updates calling code to reference the new
class instead of CWallet.

Most of the changes are simple text replacements and variable substitutions
easily verified with:

    git log -p -n1 -U0 --word-diff-regex=.

The only nontrivial chunk of code added is the new LegacyScriptPubKeyMan class
declaration, but this code isn't new and is just selectively copied and moved
from the previous CWallet class declaration. This can be verified with:

    git log -p -n1 --color-moved=dimmed_zebra src/wallet/scriptpubkeyman.h src/wallet/wallet.h

or

    git diff HEAD~1:src/wallet/wallet.h HEAD:src/wallet/scriptpubkeyman.h

Merge #16524: Wallet: Disable -fallbackfee by default
ea4cc3a7b3 Truly decouple wallet from chainparams for -fallbackfee (Jorge Timón)

Pull request description:

  Before it was 0 by default for main and 20000 for test and regtest.
  Now it is 0 by default for all chains, thus there's no need to call Params().

  Also now the default for main is properly documented.

  Suggestion for release notes:

  -fallbackfee was 0 (disabled) by default for the main chain, but 20000 by default for the test chains. Now it is 0 by default for all chains. Testnet and regtest users will have to add fallbackfee=20000 to their configuration if they weren't setting it and they want it to keep working like before.

  Should I propose them to the wiki for the release notes or only after merge?

Merge #16624: wallet: encapsulate transactions state
442a87cc0a Add a test wallet_reorgsrestore (Antoine Riard)
40ede992d9 Modify wallet tx status if has been reorged out (Antoine Riard)
7e89994133 Remove SyncTransaction for conflicted txn in CWallet::BlockConnected (Antoine Riard)
a31be09bfd Encapsulate tx status in a Confirmation struct (Antoine Riard)

Pull request description:

  While working on #15931, I've tried to rationalize tx state management to ease integration of block height tracking per-wallet tx. We currently rely on a combination of `hashBlock` and `nIndex` with magic value to determine tx confirmation, conflicted or abandoned state. It's hard to reason and error-prone.  To solve that, we encapsulate these fields in a `TxConfirmation` struct and introduce a `TxState` member that we update accordingly at block connection/disconnection.

  Following jnewbery [recommendation](https://github.com/bitcoin/bitcoin/pull/15931#discussion_r312576506), I've taken these changes in its own commit, and open a PR to get them first. It would ease review of aforementioned PR, but above all should ease fixing of long-term issues like :
  * https://github.com/bitcoin/bitcoin/issues/7315 (but maybe we should abandon abandontransaction or relieve it to only free outpoints not track the transaction as abandoned in itself, need its own discussion)
  * https://github.com/bitcoin/bitcoin/issues/8692 where we should cancel conflicted state of transactions chain smoothly
  * `MarkConflicted` in `LoadToWallet` is likely useless if we track conflicts rights at block connection

  Main changes of this PR to get right are tx update in `AddToWallet` and serialization/deserialization logic.

40ede992d9 Modify wallet tx status if has been reorged out
Add a LockChain method to CWallet to know if we can lock or query
chain state safely.

At tx loading, we rely on chain to know if hashBlock of tx is still
in main chain. If not, we set its status to unconfirmed and reset
its hashBlock/nIndex.

If wallet loaded is the wallet-tool one, all wallet txn will
show up with a height of zero. It doesn't matter as status is not
used by wallet-tool.

We take lock prematurely in CWallet::LoadWallet and CWallet::Verify
to ensure that lock order is respected between cs_main an cs_wallet.

798a589aff wallet: extract PubKey from P2PK script with Solver
The function ExtractPubKey() checks if a given script matches the P2PK pattern
(<PubKey> OP_CHECKSIG), extracts the PubKey and additionally checks if it is
cryptographically valid (full validation with ECC library via .IsFullyValid()).

Currently this is done manually in the following order:
    1) check if first script OP is data push with valid PubKey length
       (first part of pattern match), extract PubKey
    2) create CPubKey object with extracted PubKey
    3) fully validate public key
    4) check if last script OP is OP_CHECKSIG
       (second part of pattern match)

Using Solver, the pattern matching and PubKey extraction can be done via a
single step, leading to the following simplified order with shorter code:
    1) check if given script matches P2PK pattern with Solver
       (also contains valid PubKey length check), extracts Pubkey
    2) create CPubKey object with extracted Pubkey
    3) fully validate public key

7e89994133 Remove SyncTransaction for conflicted txn in CWallet::BlockConnected
We shouldn't rely on this sync call to get an accurate view of txn
state, if a tx conflicts with one in mapTx we are going to update
our wallet dependencies in AddToWalletIfInvolvingMe while conflicting
txn get connected. If it doesn't conflict with one of our dependencies
we are not going to track it anyway.

This is a cleanup, as this SyncTransaction is redundant with the
following one for confirmation which is triggering the MarkConflicted
logic. We keep the loop because set of conflicted txn isn't same as txn
included in block.

a31be09bfd Encapsulate tx status in a Confirmation struct
Instead of relying on combination of hashBlock and nIndex
values to manage tx in its lifecycle, we introduce 4
status : CONFIRMED, UNCONFIRMED, CONFLICTED, ABANDONED.

hashBlock and nIndex magic values should only be used at
serialization/deserialization for backward-compatibility.

At block disconnection, we know flag txn as UNCONFIRMED where
previously they kept their states until being override by a
block connection or abandontransaction call. This is a change
in behavior for which user may have to call abandon twice
if transaction is disconnected and not accepted back in the mempool.

We assert status transitioning right in AddToWallet. Doing so
flagged a misbehavior in ComputeTimeSmart unit test where same
tx is confirmed twice in different block. To avoid inconsistencies
we unconfirmed tx before new connection in different block. We
also remove a cs_main lock in test, as AddToWallet and its
callees don't rely on locked chain.

  - Usage of `enum class` (https://github.com/bitcoin/bitcoin/pull/16244#discussion_r296434142)
  - Placing out args at the end convention (https://github.com/bitcoin/bitcoin/pull/16244#discussion_r296434172)
  - Return error when passphrase would be ignored because of disabled private keys (including functional test) (https://github.com/bitcoin/bitcoin/pull/16244#pullrequestreview-252015195)
  - Make `status` return variable of `CreateWallet` (https://github.com/bitcoin/bitcoin/pull/16244#discussion_r302107394)
  - Using a `switch` statement instead of `if/else` in `RpcWallet` (https://github.com/bitcoin/bitcoin/pull/16244#discussion_r302112502)

  Not included was:
  - "new create wallet function [could take] separate option arguments instead of wallet flags" (https://github.com/bitcoin/bitcoin/pull/16244#pullrequestreview-252015195)
  - "blank wallet and disable private keys options could be combined into a single option" (https://github.com/bitcoin/bitcoin/pull/16244#pullrequestreview-252015195)

  For these last two changes, I was not sure what an ideal solution could look like and/or this might be of slightly larger scope than the other changes, but I would be happy to work on these as well in this PR or another follow-up if I get positive feedback on that. Is there a place in the codebase that handles flags like these in a better way that I can refer to? Nonetheless, I would prefer keeping it in a separate PR unless it is a really simple change.

Merge #16208: wallet: Consume ReserveDestination on successful CreateTransaction
e10e1e8db0 Restrict lifetime of ReserveDestination to CWallet::CreateTransaction (Gregory Sanders)
d9ff862f2d CreateTransaction calls KeepDestination on ReserveDestination before success (Gregory Sanders)

Pull request description:

  The typical usage pattern of `ReserveDestination` is to explicitly `KeepDestination`, or `ReturnDestination` when it's detected it will not be used.

  Implementers such as myself may fail to complete this pattern, and could result in key re-use: https://github.com/bitcoin/bitcoin/pull/15557#discussion_r271956393

  Since ReserveDestination is currently only used directly in the `CreateTransaction`/`CommitTransaction` flow(or fee bumping where it's just used in `CreateTransaction`), I instead make the assumption that if a transaction is returned by `CreateTransaction` it's highly likely that it will be accepted by the caller, and the `ReserveDestination` kept. This simplifies the API as well. There are very few cases where this would not be the case which may result in keys being burned.

  Those failure cases appear to be:
  `CommitTransaction` failing to get the transaction into the mempool
  Belt and suspenders check in `WalletModel::prepareTransaction`

  This PR compresses the `CWallet` chain of inheritance from 5 classes to 3 classes. `CBasicKeyStore` is renamed to `FillableSigningProvider` and some parts of it (the watchonly parts) are moved into `CWallet`. `CKeyStore` and `CCrypoKeyStore` are completely removed. `CKeyStore`'s `Have*` functions are moved into `SigningProvider` and the `Add*` moved into `FillableSigningProvider`, thus allowing it to go away entirely. `CCryptoKeyStore`'s functionality is moved into `CWallet`. The new inheritance chain is:

  ```
  SigningProvider -> FillableSigningProvider -> CWallet
  ```

  `SigningProvider` now is the class the provides keys and scripts and indicates whether keys and scripts are present. `FillableSigningProvider` allows keys and scripts to be added to the signing provider via `Add*` functions. `CWallet` handles all of the watchonly stuff (`AddWatchOnly`, `HaveWatchOnly`, `RemoveWatchOnly` which were previously in `CKeyStore`) and key encryption (previously in `CCryptoKeyStore`).

  Implements the 2nd [prerequisite](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Class-Structure-Changes#cwallet-subclass-stack) from the wallet restructure.

Pull request description:

  The wallet should give out destinations instead of keys. It should be the one that handles the conversion from key to destination and the setting of the label, not the caller. In order to do this, two new member functions are introduced `GetNewDestination()` and `GetNewChangeDestination()`. Additionally, `CReserveKey` is changed to be `ReserveDestination` and represents destinations whose keys can be returned to the keypool.

Pull request description:

  Add a new wallet flag called `avoid_reuse` which, when enabled, will keep track of when a specific destination has been spent from, and will actively "blacklist" any new UTXOs which send to an already-spent-from destination.

  This improves privacy, as a payer could otherwise begin tracking a payee's wallet by regularly peppering a known UTXO with dust outputs, which would then be scooped up and used in payments by the payee, allowing the payer to map out (1) the inputs owned by the payee and (2) the destinations to which the payee is making payments.

  This replaces #10386 and together with the (now merged) #12257 it addresses #10065 in full. The concerns raised in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381 are also addressed due to #12257.

  ~~Note: this builds on top of #15780.~~ (merged)

  This brings the behaviour of the import* calls closer to importmulti. After this change, the difference between importmulti and the other import* calls is

  * that in importmulti you can "opt-out" of scanning early blocks by setting a later timestamp.
  * that in importmulti the wallet will successfully import the data, but fail to rescan. Whereas in the other calls, the wallet will abort before importing the data.

  Specification: https://github.com/jamesob/assumeutxo-docs/tree/2019-04-proposal/proposal

  ---

  This change refactors the `chainActive` reference into a `::ChainActive()` call. It also distinguishes `CChainState`'s `CChain` data member as `m_chain` instead of the current `chainActive`, which makes it easily confused with the global data.

  The active chain must be obtained via function because its reference will be swapped at some point during runtime after loading a UTXO snapshot.

  This change, though lengthy, should be pretty easy to review since most of it is contained within a scripted-diff. Once merged, the parent PR should be easier to review.

Pull request description:

  This PR is the last in a chain of PRs (#14437, #14711, and #15288) that make the wallet code access node state through an abstract [`Chain`](https://github.com/ryanofsky/bitcoin/blob/pr/wipc-sep/src/interfaces/chain.h) class in [`src/interfaces/`](https://github.com/ryanofsky/bitcoin/tree/pr/wipc-sep/src/interfaces) instead of using global variables like `cs_main`, `chainActive`, and `g_connman`. After this PR, wallet code no longer accesses global variables declared outside the wallet directory, and no longer calls functions accessing those globals (as verified by the `hide-globals` script in #10244).

  This PR and the previous PRs have been refactoring changes that do not affect behavior. Previous PRs have consisted of lots of mechanical changes like:

  ```diff
  -    wtx.nTimeReceived = GetAdjustedTime();
  +    wtx.nTimeReceived = m_chain->getAdjustedTime();
  ```

  This PR is smaller, but less mechanical. It replaces last few bits of wallet code that access node state directly (through `CValidationInterface`, `CRPCTable`, and `CCoinsViewMemPool` interfaces) with code that uses the `Chain` interface.

  These changes allow followup PR #10102 (multiprocess gui & wallet PR) to work without any significant updates to wallet code. Additionally they:

  * Provide a single place to describe the interface between wallet and node code.
  * Can make better wallet testing possible, because the `Chain` object consists of virtual methods that can be overloaded for mocking. (This could be used to test edge cases in the rescan code, for example).

Pull request description:

  This change removes wallet calls to node functions that access global chain and mempool state.

Merge #15226: Allow creating blank (empty) wallets (alternative)
7687f7873 [wallet] Support creating a blank wallet (Andrew Chow)

Pull request description:

  Alternative (kind of) to #14938

  This PR adds a `blank` parameter to the `createwallet` RPC to create a wallet that has no private keys initially. `sethdseed` can then be used to make a clean wallet with a custom seed. `encryptwallet` can also be used to make a wallet that is born encrypted.

  Instead of changing the version number as done in #14938, a wallet flag is used to indicate that the wallet should be blank. This flag is set at creation, and then unset when the wallet is no longer blank. A wallet becomes non-blank when a HD seed is set or anything is imported. The main change to create a blank wallet is primarily taken from #14938.

  Also with this, the term "blank wallet" is used instead of "empty wallet" to avoid confusion with wallets that have balance which would also be referred to as "empty".

  This is built on top of #15225 in order to fix GUI issues.

Pull request description:

  Instead of adding BerkeleyEnvironment objects permanently to the g_dbenvs map, use reference counted shared pointers and remove map entries when the last BerkeleyEnvironment reference goes out of scope.

  This change was requested by @TheBlueMatt and makes code that sets up mock databases cleaner. The mock database environment will now go out of scope and be reset on destruction so there is no need to call BerkeleyEnvironment::Reset() during wallet construction to clear out prior state.

  This change does affect bitcoin behavior slightly. On startup, instead of same wallet environments staying open throughout VerifyWallets() and OpenWallets() calls, VerifyWallets() will open and close an environment once for each wallet, and OpenWallets() will create its own environment(s) later.

Pull request description:

  Adds an offline tool `bitcoin-wallet-tool` for wallet creation and maintenance.

  Currently this tool can create a new wallet file, display information on an existing wallet, and run the salvage and zapwallettxes maintenance tasks on an existing wallet. It can later be extended to support other common wallet maintenance tasks.

  Doing wallet maintenance tasks in an offline tool makes much more sense (and is potentially safer) than having to spin up a full node.

Merge #15225: GUI: Change the receive button to respond to keypool state changing
2bc4c3eaf9 Notify the GUI that the keypool has changed to set the receive button (Andrew Chow)
14bcdbe09c Check for more than private keys disabled to show receive button (Andrew Chow)

Pull request description:

  Currently the Receive button in the GUI is displayed enabled or disabled by the initial state of the wallet when the wallet is first loaded. The button is only enabled or disabled depending on whether the disable private keys flag is set when the wallet is loaded. However, future changes to the wallet means that this initial state and check may no longer be accurate. #14938 introduces empty wallets which do not have private keys. An empty wallet that is loaded should have the Receive button disabled, and then it should become enabled once `sethdseed` is used so that a keypool can be generated and new keys generated. Likewise, with #14075, a wallet can be loaded with no keypool initially, so the button should be disabled. Later, public keys can be imported into the keypool, at which time the button should become enabled. When the keypool runs out again (no new keys are generated as the keypool only consists of imports), the button should become disabled.

  This PR makes it so that the button becomes enabled and disabled as the keypool state changes. The check for whether to enable or disable the receive button has changed to checking whether it is possible to get new keys. It now checks for whether the wallet has an HD seed and, if not, whether the private keys are disabled. When an action happens which would make it possible for a new address to be retrieved or make it possible for a no more addresses to be retrieved, a signal is emitted which has the GUI recheck the conditions for the Receive button. These actions are setting a new HD seed, topping up the keypool, retrieving a key from the keypool, and returning a key to the keypool.

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 #14821: Replace CAffectedKeysVisitor with descriptor based logic
0e75f44a0 Replace CAffectedKeysVisitor with descriptor based logic (Pieter Wuille)

Pull request description:

  It seems we don't need a custom visitor pattern anymore to find what keys are affected by a script. Instead, infer the descriptor, and see which keys it expands to.

Merge #14380: fix assert crash when specified change output spend size is unknown
0fb2e69815 CreateTransaction: Assume minimum p2sh-p2wpkh spend size for unknown change (Gregory Sanders)
b06483c96a Remove stale comment in CalculateMaximumSignedInputSize (Gregory Sanders)

Pull request description:

  This is triggered anytime a fundraw type call(psbt or legacy) is used with a change output address that the wallet doesn't know how to sign for.

  This regression was added in 6a34ff5335 since BnB coin selection actually cares about this.

  The fix is to assume the smallest typical spend, a P2SH-P2WPKH, which is calculated using a "prototype" dummy signature flow. Future work could generalize this infrastructure to get estimated sizes of inputs for a variety of types.

  I also removed a comment which I believe is stale and misleading.

f1f4bb7345 Free BerkeleyEnvironment instances when not in use
Instead of adding BerkeleyEnvironment objects permanently to the g_dbenvs map,
use reference counted shared pointers and remove map entries when the last
BerkeleyEnvironment reference goes out of scope.

This change was requested by Matt Corallo <git@bluematt.me> and makes code that
sets up mock databases cleaner. The mock database environment will now go out
of scope and be reset on destruction so there is no need to call
BerkeleyEnvironment::Reset() during wallet construction to clear out prior
state.

This change does affect bitcoin behavior slightly. On startup, instead of same
wallet environments staying open throughout VerifyWallets() and OpenWallets()
calls, VerifyWallets() will open and close an environment once for each wallet,
and OpenWallets() will create its own environment(s) later.

  Fix #14538

  Fix crash attempting to load the same wallet with different path strings that resolve to the same absolute path. The primary check which prevents loading the same wallet twice is:

  6b8d0a2164/src/wallet/db.cpp (L44)

  But this check is skipped if both wallet paths resolve to the same absolute path, due to caching here:

  6b8d0a2164/src/wallet/db.cpp (L467)

  Meanwhile a secondary check for duplicate wallets is not reliable because it based on a literal comparison, instead of comparison using absolute paths:

  6b8d0a2164/src/wallet/wallet.cpp (L3853)

  This PR fixes the latter check to compare the absolute path of a new wallet being loaded to absolute paths of wallets already loaded, so there should no longer be any way to load the same wallet more than once.

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.

Pull request description:

  This is the replacement for #11678 which implements @ryanofsky's [suggestion](https://github.com/bitcoin/bitcoin/pull/11678#pullrequestreview-76464511).

  Shutting down the software was to prevent the BDB environment from writing unencrypted private keys to disk in the database log files, as was noted [here](https://bitcointalk.org/index.php?topic=51474.msg616068#msg616068). This PR replaces the shutdown behavior with a CDBEnv flush, close, and reopen which achieves the same effect: everything is cleanly flushed and closed, the log files are removed, and then the environment reopened to continue normal operation.

  To ensure that no unencrypted private keys are in the log files after encrypting the wallet, I wrote [this script](https://gist.github.com/achow101/7f7143e6c3d3fdc034d3470e72823e9d) to pull private keys from the original wallet file and searches for these keys in the log files (note that you will have to change your file paths to make it work on your own machine).

  As for concerns about private keys being written to slack space or being kept in memory, these behaviors no longer exist after the original wallet encryption PR and the shutting down solution from 2011.

Pull request description:

  Based on conversation in #13462, it seems the serialization `GetType` has very narrow use/effect. In every case except for `CAddress`, which specifically relates to a network peer's address, not a wallet address etc., the serialized representation of an object is irrespective of its destination / type.

  This removes the unused `GetType` method from `CSizeComputer` as a step to further narrowing that use.

Pull request description:

  This PR adds "key origin" (master fingeprint + key path) information to what is exposed from `SigningProvider`s, allowing this information to be used by the generic PSBT code instead of having the RPC pull it directly from the wallet.

  This is also a preparation to having PSBT interact with output descriptors, which can then directly expose key origin information for the scripts they generate.

Merge #13666: Always create signatures with Low R values
e306be7429 Use 72 byte dummy signatures when watching only inputs may be used (Andrew Chow)
48b1473c89 Use 71 byte signature for DUMMY_SIGNATURE_CREATOR (Andrew Chow)
18dfea0dd0 Always create 70 byte signatures with low R values (Andrew Chow)

Pull request description:

  When creating signatures for transactions, always make one which has a 32 byte or smaller R and 32 byte or smaller S value. This results in signatures that are always less than 71 bytes (32 byte R + 32 byte S + 6 bytes DER + 1 byte sighash) with low R values. In most cases, the signature will be 71 bytes.

  Because R is not mutable in the same way that S is, a low R value can only be found by trying different nonces. RFC 6979 for deterministic nonce generation has the option to specify additional entropy, so we simply use that and add a uin32_t counter which we increment in order to try different nonces. Nonces are sill deterministically generated as the nonce used will the be the first one where the counter results in a nonce that results in a low R value. Because different nonces need to be tried, time to produce a signature does increase. On average, it takes twice as long to make a signature as two signatures need to be created, on average, to find one with a low R.

  Having a fixed size signature makes size calculations easier and also saves half a byte of transaction size, on average.

  DUMMY_SIGNATURE_CREATOR has been modified to produce 71 byte dummy signatures instead of 72 byte signatures.

e306be7429 Use 72 byte dummy signatures when watching only inputs may be used
With watching only inputs, we do not know how large the signatures
for those inputs will be as their signers may not have implemented
71 byte signatures. Thus we estimate their fees using the 72 byte
dummy signature to ensure that we pay enough fees.

This only effects fundrawtransaction when includeWatching is true.

Pull request description:

  This PR adds an optional (off by default) `-avoidpartialspends` flag, which changes coin select to use output groups rather than outputs, where each output group corresponds to all outputs with the same destination.

  It is a privacy improvement, as each time you spend some output, any other output that is publicly associated with the destination (address) will also be spent at the same time, at the cost of fee increase for cases where coin select without group restriction would find a more optimal set of coins (see example below).

  For regular use without address reuse, this PR should have no effect on the user experience whatsoever; it only affects users who, for some reason, have multiple outputs with the same destination (i.e. address reuse).

  Nodes with this turned off will still try to avoid partial spending, if the fee of the resulting transaction is not greater than the fee of the original transaction.

  Example: a node has four outputs linked to two addresses `A` and `B`:

  * 1.0 btc to `A`
  * 0.5 btc to `A`
  * 1.0 btc to `B`
  * 0.5 btc to `B`

  The node sends 0.2 btc to `C`. Without `-avoidpartialspends`, the following coin selection will occur:
  * 0.5 btc to `A` or `B` is picked
  * 0.2 btc is output to `C`
  * 0.3 - fee is output to (unique change address)

  With `-avoidpartialspends`, the following will instead happen:
  * Both of (0.5, 1.0) btc to `A` or `B` is picked (one or the other pair)
  * 0.2 btc is output to `C`
  * 1.3 - fee is output to (unique change address)

  As noted, the pro here is that, assuming nobody sends to the address after you spend from it, you will only ever use one address once. The con is that the transaction becomes slightly larger in this case, because it is overpicking outputs to adhere to the no partial spending rule.

  This complements #10386, in particular it addresses @luke-jr and @gmaxwell's concerns in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-300667926 and https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381.

  Together with `-avoidreuse`, this fully addresses the concerns in #10065 I believe.

  This mode ('createwallet {"disableprivatekeys": true}') is intended for a sane pure watch-only mode, ideal for a use-case where one likes to use Bitcoin-Core in conjunction with a hardware-wallet or another solutions for cold-storage.

  Since we have support for custom change addresses in `fundrawtransaction`, pure watch-only wallets including coin-selection are possible and do make sense for some use cases.

  This new mode disables all forms of private key generation and ensure that no mix between hot and cold keys are possible.

Merge #13566: Fix get balance
702ae1e21a [RPC] [wallet] allow getbalance to use min_conf and watch_only without accounts. (John Newbery)
cf15761f6d [wallet] GetBalance can take a min_depth argument. (John Newbery)
0f3d6e9ab7 [wallet] factor out GetAvailableWatchOnlyBalance() (John Newbery)
7110c830f8 [wallet] deduplicate GetAvailableCredit logic (John Newbery)
ef7bc8893c [wallet] Factor out GetWatchOnlyBalance() (John Newbery)
4279da4785 [wallet] GetBalance can take an isminefilter filter. (John Newbery)

Pull request description:

  #12953 inadvertently removed the functionality to call `getbalance "*" <int> <bool>` to get the wallet's balance with either minconfs or include_watchonly.

  This restores that functionality (when `-deprecatedrpc=accounts`), and also makes it possible to call ``getbalance minconf=<int> include_watchonly=<bool>` when accounts are not being used.

Merge #12944: [wallet] ScanforWalletTransactions should mark input txns as dirty
3c292cc19 ScanforWalletTransactions should mark input txns as dirty (Gregory Sanders)

Pull request description:

  I'm hitting a corner case in my mainnet wallet where I load a restore a wallet, call `rescanblockchain` from RPC, and it's "double counting" an output I've sent to myself since currently it never marks input transactions as dirty. This is fixed by a restart of the wallet.

  Note that this only happens with keys with birthdate *after* the blocks containing the spent funds which gets scanned on startup, so it's hard to test without a set seed function.
