introduction of the fs_helpers.* it makes sense to move fs.* into the

These belong in libbitcoin_common.a, not libbitcoin_util.a, because they aren't
general-purpose utilities, they just contain common code that is used by both
the node and the wallet. Another reason to reason to not include these in
libbitcoin_util.a is to prevent them from being used by the kernel library.
This is useful for speeding up wallet rescans and is based on an
earlier version from PR #15845 ("wallet: Fast rescan with BIP157 block
filters"), which was never merged.

This makes a number of changes:
- Get rid of the verification_progress argument in the node interface
NotifyHeaderTip (it was always 0.0).
- Instead of passing a CBlockIndex* in the UI interface's NotifyHeaderTip,
send separate height, timestamp fields. This is becuase in headers presync,
no actual CBlockIndex object is available.
- Add a bool presync argument to both of the above, to identify signals
pertaining to the first headers sync phase.

1f798fe85b wallet: Cache SigningProviders (Andrew Chow)
8a105ecd1a 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.
Replace CommitInternal method with CustomCommit and use interfaces::Chain
instead of CChainState to generate block locator.
This commit does not change behavior in any way, except in the
(m_best_block_index == nullptr) case, which was added recently in
https://github.com/bitcoin/bitcoin/pull/24117 as part of an ongoing attempt to
prevent index corruption if bitcoind is interrupted during startup. New
behavior in that case should be slightly better than the old behavior (skipping
the entire custom+base commit now vs only skipping the base commit previously)
and this might avoid more cases of corruption.
Add new interfaces::BlockInfo struct to be able to pass extra block
information (file and undo information) to indexes which they are
updated to use high level interfaces::Chain notifications.
This commit does not change behavior in any way.
817326a828 wallet: avoid rescans if under the snapshot (James O'Beirne)
Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11) (parent PR: #15606)
---
Refuse to load a wallet if it requires a rescan lower than the height of assumed-valid blocks.
Of course in live code right now, `BLOCK_ASSUMED_VALID` block index entries don't exist since they're a unique flag introduced by the use of UTXO snapshots, so this is prophylactic code exercised only by unittests.

198fcca162 wallet: refactor, include 'FeeCalculation' inside 'CreatedTransactionResult' (furszy)
7a45c33d1f Introduce generic 'Result' class (furszy)
Pull request description:
Based on a common function signature pattern that we have all around the sources:
```cpp
bool doSomething(arg1, arg2, arg3, arg4, &result_obj, &error_string) {
// do something...
if (error) {
error_string = "something bad happened";
return false;
}
result = goodResult;
return true;
}
```
Introduced a generic class `BResult` that encapsulate the function boolean result, the result object (in case of having it) and, in case of failure, the string error reason.
Obtaining in this way cleaner function signatures and removing boilerplate code:
```cpp
BResult<Obj> doSomething(arg1, arg2, arg3, arg4) {
// do something...
if (error) return "something bad happened";
return goodResult;
}
```
Same cleanup applies equally to the function callers' side as well. There is no longer need to add the error string and the result object declarations before calling the function:
Before:
```cpp
Obj result_obj;
std::string error_string;
if (!doSomething(arg1, arg2, arg3, arg4, result_obj, error_string)) {
LogPrintf("Error: %s", error_string);
}
return result_obj;
```
Now:
```cpp
BResult<Obj> op_res = doSomething(arg1, arg2, arg3, arg4);
if (!op_res) {
LogPrintf("Error: %s", op_res.GetError());
}
return op_res.GetObjResult();
```
### Initial Implementation:
Have connected this new concept to two different flows for now:
1) The `CreateTransaction` flow. --> 7ba2b87c
2) The `GetNewDestination` flow. --> bcee0912
Happy note: even when introduced a new class into the sources, the amount of lines removed is almost equal to added ones :).
Extra note: this work is an extended version (and a decoupling) of the work that is inside #24845 (which does not contain the `GetNewDestination` changes nor the inclusion of the `FeeCalculation` field inside `CreatedTransactionResult`).

Allows the GUI to clear settings.json file and save settings.json.bak file when
GUI "Reset Options" button is pressed or -resetguisettings command line option
is used. (GUI code already backs up and resets the "guisettings.ini" file this
way, so this just makes the same behavior possible for "settings.json")
Add interfaces::Node methods to give GUI finer grained control over
settings.json file. Update method is used to write settings to the file,
getPersistent and isIgnored methods are used to find out about settings
file and command line option interactions.

90fc8b089d Add src/node/* code to node:: namespace (Russell Yanofsky)
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.

`fs::path` looks more native than `std::string` for a parameter which
represents a backup file. This change eliminates back-and-forth type
conversions.
Name has been confusing since it was introduced, and it was pointed in
recent review club as https://bitcoincore.reviews/10102 that it was
particularly unclear how interfaces::WalletClient was different from
interfaces::Wallet.

fa3e0da06b policy: Treat taproot as always active (MarcoFalke)
Pull request description:
Now that taproot is active, it can be treated as if it was always active for policy for the next major release. This simplifies the code and changes two things:
* Importing `tr` descriptors can be done before the chain is fully synced. This is fine, because the wallet will already generate `tr` descriptors by default (regardless of the taproot status) after commit 47fe7445e7.
* Valid taproot spends won't be rejected from the mempool before taproot is active. This is strictly speaking a bugfix after commit 47fe7445e7, since the wallet may generate taproot spends before the chain is fully synced. For example, a slow node or a purposefully offline node. Currently, the wallet needs the mempool to account for change. See https://github.com/bitcoin/bitcoin/issues/11887.
A similar change was done for segwit v0 in https://github.com/bitcoin/bitcoin/pull/13120 .
This effectively reverts commit c5ec0367d7.

5c5d0b6264 Add FoundBlock.found member (Russell Yanofsky)
Pull request description:
This change lets IPC serialization code handle FoundBlock arguments more simply and efficiently. Without this change there was no way to determine from a FoundBlock object whether a block was found or not. So in order to correctly implement behavior of leaving FoundBlock output variables unmodified when a block was not found, IPC code would have to read preexisting output variable values from the local process, send them to the remote process, receive output values back from the remote process, and save them to output variables unconditionally. With FoundBlock.found method, the process is simpler. There's no need to read or send preexisting local output variable values, just to read final output values from the remote process and set them conditionally if the block was found.

This change lets IPC serialization code handle FoundBlock arguments more
simply and efficiently. Without this change there was no way to
determine from a FoundBlock object whether a block was found or not. So
in order to correctly implement behavior of leaving FoundBlock output
variables unmodified when a block was not found, IPC code would have to
read preexisting output variable values from the local process, send
them to the remote process, receive output values back from the remote
process, and save them to output variables unconditionally. With
FoundBlock.found method, the process is simpler. There's no need to read
or send preexisting local output variable values, just to read final
output values from the remote process and set them conditionally if the
block was found.
These are currently empty structs but they will be used to pass some
function and object pointers from bitcoin application code to IPC hooks
that run, for example, when a remote object is created or destroyed, or
a new process is created.
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.

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.

fa4e088cba wallet: Mark replaced tx to not be in the mempool anymore (MarcoFalke)
Pull request description:
The wallet does not mark the replaced tx as out-of-mempool. This causes failures in user scripts, because later RPCs may depend on this state change from `bumpfee`.
For example, the following might fail on current master:
```
txid = sendtoaddress(...)
bumpfee(txid)
abandontransaction(txid) # fails because txid is still marked as "in mempool"
```
Fixes#18831

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.
Note: No user-visible behavior is changing in this commit. New
CWallet::SetAddressReceiveRequest() implementation avoids a bug in
CWallet::AddDestData() where a modification would leave the previous
value in memory while writing the new value to disk. But it doesn't
matter because the GUI doesn't currently expose the ability to modify
receive requests, only to add and erase them.
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.
No longer create a default wallet. The default wallet will still be
loaded if it exists and not other wallets were specified (anywhere,
including settings.json, bitcoin.conf, and command line).
Tests are updated to be started with -wallet= if they need the default
wallet.
Added test to wallet_startup.py testing that no default wallet is
created and that it is loaded if it exists and no other wallets were
specified.

Pull request description:
Get rid of file path handling in wallet application code and move it down to database layer.
There is no change in behavior except for some changed error messages.
Motivation for this change is to make code more understandable, but also to prepare for adding SQLite support in #19077 so SQLite implementation can be contained at the database layer and wallet loading code does not need to become more complicated.
