Merge #19501: send* RPCs in the wallet returns the "fee reason"
69cf5d4eeb [test] Make sure send rpc returns fee reason (Sishir Giri)
d5863c0b3e [send] Make send RPCs return fee reason (Sishir Giri)

Pull request description:

  Whenever a wallet funds a transaction, the fee reason is reported to the user only if the verbose is set to true. I added an extra parameter to `CreateTransaction` function in wallet.cpp. Then I implemented the fee reason return logic in `SendMoney`  in rpcwallet.cpp, followed by verbose parameter in `sendtoaddress` and `sendmany` functions. I also added a fee reason test case in walletbasic.py.

e76fc2b84d Add 'sequence' zmq publisher to track all block (dis)connects, mempool deltas
Using the zmq notifications to avoid excessive mempool polling can be difficult
given the current notifications available. It announces all transactions
being added to mempool or included in blocks, but announces no evictions
and gives no indication if the transaction is in the mempool or a block.

Block notifications for zmq are also substandard, in that it only announces
block tips, while all block transactions are still announced.

This commit adds a unified stream which can be used to closely track mempool:

1) getrawmempool to fill out mempool knowledge
2) if txhash is announced, add or remove from set
based on add/remove flag
3) if blockhash is announced, get block txn list,
remove from those transactions local view of mempool
4) if we drop a sequence number, go to (1)

The mempool sequence number starts at the value 1, and
increments each time a transaction enters the mempool,
or is evicted from the mempool for any reason, including
block inclusion. The mempool sequence number is published
via ZMQ for any transaction-related notification.

These features allow for ZMQ/RPC consumer to track mempool
state in a more exacting way, without unnecesarily polling
getrawmempool. See interface_zmq.py::test_mempool_sync for
example usage.

assign some value to the 'status', but LoadWallet() does not do so
in some situation.

f1ee37319a wallet: Reload previously loaded wallets on GUI startup (Andrew Chow)

Pull request description:

Merge #18244: rpc: fundrawtransaction and walletcreatefundedpsbt also lock manually selected coins
6d1f51343c [rpc] fundrawtransaction, walletcreatefundedpsbt lock manually selected coins (Sjors Provoost)

Pull request description:

  When using `fundrawtransaction` and `walletcreatefundedpsbt` with `lockUnspents`, it would only lock automatically selected coins, not manually selected coins. That doesn't make much sense to me if the goal is to prevent accidentally double-spending yourself before you broadcast a transaction.

  Note that when  creating a transaction, manually selected coins are automatic "unlocked" (or more accurately: the lock is ignored). Earlier versions of this PR introduced an error when a locked coin is manually selected, but this idea was abandoned after some discussion. An application that uses this RPC should either rely on automatic coin selection (with `lockUnspents`) or handle lock concurrency itself with manual coin selection. In particular it needs to make sure to avoid/pause calls with automatic coin selection between calling `lockunspent` and the subsequent spending RPC.

  See #7518 for historical background.

Merge #14582: wallet: always do avoid partial spends if fees are within a specified range
7f13dfb587 test: test the implicit avoid partial spends functionality (Karl-Johan Alm)
b82067bf69 wallet: try -avoidpartialspends mode and use its result if fees are below threshold (Karl-Johan Alm)

Pull request description:

  The `-avoidpartialspends` feature is normally disabled, as it may affect the optimal fee for payments. This PR introduces a new parameter `-maxapsfee` (max avoid partial spends fee) which acts on the following values:
  * -1: disable partial spend avoidance completely (do not even try it)
  * 0: only do partial spend avoidance if fees are the same or better as the regular coin selection
  * 1..∞: use APS variant if the absolute fee difference is less than or equal to the max APS fee

  For values other than -1, the code will now try partial spend avoidance once, and if that gives a value within the accepted range, it will use that.

  Example: -maxapsfee=0.00001000 means the wallet will do regular coin select, APS coin select, and then pick AKS iff the absolute fee difference is <= 1000 satoshi.

  Edit: updated this to reflect the fact we are now using a max fee.

Merge #19568: Wallet should not override signing errors
e7448d6680 wallet: Don't override signing errors (Fabian Jahr)

Pull request description:

  While reviewing #17204 I noticed that the errors in `input_errors` from `::SignTransaction` where being overridden by `CWallet::SignTransaction`. For example, a Script related error led to incomplete signature data which led to `CWallet::SignTransaction` reporting that keys were missing, which was a less precise error than the original one.

  Additionally, the error `"Input not found or already spent"` is [duplicated in `sign.cpp`](c7b4968552/src/script/sign.cpp (L481)), so the error here is redundant at the moment. So technically the whole error block could be removed, I think. However, this code is affected by the ongoing work on the wallet so there might be a reason why these errors are here. But even if there is a reason to keep them, I don't think existing, potentially more precise errors should be overridden here unless we want to hide them from the users. I am looking for feedback if this is a work in progress state where these errors could be more useful in the future or if they can be removed.

  On testing: even though [the errors in `CWallet` are covered](https://marcofalke.github.io/btc_cov/total.coverage/src/wallet/wallet.cpp.gcov.html), all tests still pass after removing them. I am not sure if there is a desire to cover these specific error messages, tests in `test/functional/rpc_signrawtransaction.py` seem to aim for a more generic approach.

d9cd095b59 Split SetActiveScriptPubKeyMan into Add/LoadActiveScriptPubKeyMan (Andrew Chow)
0122fbab4c Split SetHDChain into AddHDChain and LoadHDChain (Andrew Chow)

Pull request description:

  `SetHDChaiin`, `SetActiveScriptPubKeyMan`, and `SetWalletFlags` have a `memonly` argument which is kind of confusing, as noted in https://github.com/bitcoin/bitcoin/pull/17681#discussion_r427633081. This PR replaces those functions with `Add*` and `Load*` variants so that they follow the pattern used elsewhere in the wallet.

  `AddHDChain`, `AddActiveScriptPubKeyMan`, and `AddWalletFlags` both set their respective variables in `CWallet` and writes them to disk. These functions are used by the actions which modify the wallet such as `sethdseed`, `importdescriptors`, and creating a new wallet.

  `LoadHDChain`, `LoadActiveScriptPubKeyMan`, and `LoadWalletFlags` just set the `CWallet` variables. These functions are used by `LoadWallet` when loading the wallet from disk.

91d109156d walletdb: Move PeriodicFlush into WalletDatabase (Andrew Chow)
8f1bcf8b7b walletdb: Combine VerifyDatabaseFile and VerifyEnvironment (Andrew Chow)

Pull request description:

  The `BerkeleyBatch` class has 4 static functions that operate on `BerkeleyDatabase` or `BerkeleyEnvironment`. It doesn't make sense for these to be standalone nor for them to be static functions. So instead, move them from `BerkeleyBatch` into `BerkeleyDatabase` and make them member functions instead of static.

  `BerkeleyBatch::VerifyEnvironment` and `BerkeleyBatch::VerifyDatabaseFile` are combined into a single `BerkeleyDatabase::Verify` function that operates on that `BerkeleyDatabase` object.

  `BerkeleyBatch::Rewrite` and `BerkeleyBatch::PeriodicFlush` both took a `BerkeleyDatabase` as an argument and did stuff on it. So we just make it a member function so it doesn't need to take a database as an argument.

  Part of #18971

72f6bec1da rpc: show both UTXOs in decodepsbt (Andrew Chow)

Pull request description:

  Due to recent changes to hardware wallets, the full previous transaction will need to be provided for segwit inputs. Since some software may be checking for the existence of a `witness_utxo` to determine whether to produce a segwit signature, we keep that field to ease the transition.

  Because all of the sanity checks implemented by the `IsSane` functions were related to having mixed segwit and non-segwit data in a PSBT, those functions are removed as those checks are no longer proper.

  Some tests are updated/removed to accommodate this and a simple test added to check that both UTXOs are being added to segwit inputs.

  As discussed in the wallet IRC meeting, our own signer will not require `non_witness_utxo` for segwit inputs.

Pull request description:

  `OutputType::CHANGE_AUTO` is problematic for several reasons:

  * An output that is not change must never be described by `CHANGE_AUTO`. Simply allowing that option makes the code confusing and review harder than it needs to be.
  * To make review even harder, `CHANGE_AUTO` requires `-Wswitch` to be disabled for `OutputType`

  Fix both issues by removing `CHANGE_AUTO` and then enabling `-Wswitch` for `OutputType`

  This PR handles concurrent wallet loading.

  This can be tested by running in parallel the following script a couple of times:
  ```sh
  for i in {1..10}
  do

    src/bitcoin-cli -regtest unloadwallet foo
  done
  ```

  Eventually the error occurs:
  ```
  error code: -4
  error message:

  ```

  For reference, loading and already loaded wallet gives:
  ```
  error code: -4
  error message:
  Wallet file verification failed. Error loading wallet w1. Duplicate -wallet filename specified.

9e7b23b733 Improve TransactionErrorString messages. (Glenn Willen)

Pull request description:

  Add a "PSBT Operations" dialog, reached from the "Load PSBT..." menu item, giving options to sign or broadcast the loaded PSBT as appropriate, as well as copying the result to the clipboard or saving it to a file.

  This is based on Sjors' #17509, and depends on that PR going in first. (It effectively replaces the small "load PSBT" dialog from that PR with a more feature-rich one.)

  Some notes:
  * The way I display status information is maybe unusual (a status bar, rather than messageboxes.) I think it's helpful to have the information in it be persistent rather than transitory. But if people dislike it, I would probably move the "current state of the transaction" info to the top line of the main label, and the "what action just happened, and did it succeed" info into a messagebox.
  * I don't really know much about the translation/localization stuff. I put tr() in all the places it seemed like it ought to go. I did not attempt to translate the result of TransactionErrorString (which is shared by GUI and non-GUI code); I don't know if that's correct, but it matches the "error messages in logs should be googleable in English" heuristic. I don't know whether there are things I should be doing to reduce translator effort (like minimizing the total number of distinct message strings I use, or something.)
  * I don't really know how (if?) automated testing is applied to GUI code. I can make a list of PSBTs exercising all the codepaths for manual testing, if that's the right approach. Input appreciated.

79804fe24b [rpc] walletcreatefundedpsbt: don't automatically append inputs (Sjors Provoost)

Pull request description:

  When the user doesn't specificy inputs, it makes sense to automatically select them. But when the user does specify inputs, `walletcreatefundedpsbt` now fails if the amount is insufficient, unless `addInputs` is set to `true`.

  Similarly for `fundrawtransaction` if the original transaction already specified inputs, we only add more if `addInputs` is set to `true`.

  This protects against fat finger mistakes in the amount or fee rate (see also #16257). The behavior is also more similar to GUI coin selection.

77b79fa6ef refactor: Error message bilingual_str consistency
- Move the decision whether to translate an error message to where it is
  defined. This simplifies call sites: no more `InitError(Untranslated(...))`.

- Make all functions in `util/error.h` consistently return a
  `bilingual_str`. We've decided to use this as error message type so
  let's roll with it.

This has no functional changes: no messages are changed, no new
translation messages are defined.

Merge #9381: Remove CWalletTx merging logic from AddToWallet
28b112e9bd Get rid of BindWallet (Russell Yanofsky)
d002f9d15d Disable CWalletTx copy constructor (Russell Yanofsky)
65b9d8f8dd Avoid copying CWalletTx in LoadToWallet (Russell Yanofsky)

2b9cba2065 Remove CWalletTx merging logic from AddToWallet (Russell Yanofsky)

Pull request description:

  This is a pure refactoring, no behavior is changing.

  Instead of AddToWallet taking a temporary CWalletTx object and then potentially merging it with a pre-existing CWalletTx, have it take a callback so callers can update the pre-existing CWalletTx directly.

  This makes AddToWallet simpler because now it is only has to be concerned with saving CWalletTx objects and not merging them.

  This makes AddToWallet calls clearer because they can now make direct updates to CWalletTx entries without having to make temporary objects and then worry about how they will be merged.

  Motivation for this change came from the bumpfee PR #8456 where we wanted to be able to call AddToWallet to make a simple update to an existing transaction, but were reluctant to, because the existing CWalletTx merging logic did not apply and seemed dangerous try to update as part of that PR. After this refactoring, the bumpfee PR could call AddToWallet safely instead of implementing a duplicate AddToWallet function.

  This also allows getting rid of the CWalletTx copy constructor to prevent unintentional copying.

wallet: error if an explicit fee rate was given but the needed fee rate differed
This avoids cases where a user requests a fee rate below the minimum and is silently overruled by the wallet.

ca2a09640f Change SetType to SetInternal and remove m_address_type
m_address_type was used for two things:
1. Determine the type of descriptor to generate during
   SetupDescriptorGeneration
2. Sanity check during GetNewDestination.

There is no need to have this variable to accomplish those things.
1. Add a argument to SetupDescriptorGeneration indicating the address
   type to use
2. Use Descriptor::GetOutputType for the sanity check.

wallet: Avoid translating RPC errors when loading wallets
Common errors and warnings should be translated when displayed in the
GUI, but not translated when displayed elsewhere. The wallet method
CreateWalletFromFile does not know its caller, so this commit changes it
to return a bilingual_str to the caller.

6a72f26968 [wallet] Remove locked_chain from CWallet, its RPCs and tests
This change is intended to make the bitcoin node and its rpc, network
and gui interfaces more responsive while the wallet is in use. Currently
because the node's cs_main mutex is always locked before the wallet's
cs_wallet mutex (to prevent deadlocks), cs_main currently stays locked
while the wallet does relatively slow things like creating and listing
transactions.

This commit only remmove chain lock tacking in wallet code, and invert
lock order from cs_main, cs_wallet to cs_wallet, cs_main.
must happen at once to avoid any deadlock. Previous commit were only
removing Chain::Lock methods to Chain interface and enforcing they
take cs_main.

Remove LockChain method from CWallet and Chain::Lock interface.

Pull request description:

  This PR introduces mempool tracking of unbroadcast transactions and periodic reattempts at initial broadcast. This is a part of the rebroadcast project, and a standalone privacy win.

  The current rebroadcast logic is terrible for privacy because 1. only the source wallet rebroadcasts transactions and 2. it does so quite frequently. In the current system, if a user submits a transaction that does not immediately get broadcast to the network (eg. they are offline), this "rebroadcast" behavior is the safety net that can actually serve as the initial broadcast. So, keeping the attempts frequent is important for initial delivery within a reasonable timespan.

  This PR aims to improve # 2 by reducing the wallet rebroadcast frequency to ~1/day from ~1/15 min. It achieves this by separating the notion of initial broadcast from rebroadcasts. With these changes, the mempool tracks locally submitted transactions & periodically reattempts initial broadcast. Transactions submitted via the wallet or RPC are added to an "unbroadcast" set & are removed when a peer sends a `getdata` request, or the transaction is removed from the mempool. Every 10-15 minutes, the node reattempts an initial broadcast. This enables reducing the wallet rebroadcast frequency while ensuring the transactions will be propagated to the network.

  For privacy improvements around # 1, please see #16698.
  Thank you to gmaxwell for the idea of how to break out this subset of functionality (https://github.com/bitcoin/bitcoin/pull/16698#issuecomment-571399346)

dc1da48dc5 [wallet] Update the rebroadcast frequency to be ~1/day.
Since the mempool unbroadcast mechanism handles the reattempts for initial
broadcast, the wallet rebroadcast attempts can be much less frequent
(previously ~1/30 min)
