b27682593266c99507c720855cb34f5f7d363dd2 bench: Add a benchmark for ismine (Ava Chow)
Pull request description:
Wallets that have a ton of non-ranged descriptors (such as a migrated non-HD wallet) perform fairly poorly due to looping through all of the wallet's `ScriptPubKeyMan`s. This is done in various places, such as `IsMine`, and helper functions for fetching a `ScriptPubKeyMan` and a `SolvingProvider`. This also has a bit of a performance impact on standard descriptor wallets, although less noticeable due to the small number of SPKMs.
As these functions are based on doing `IsMine` for each `ScriptPubKeyMan`, we can improve this performance by caching `IsMine` scriptPubKeys for all descriptors and use that to determine which `ScriptPubKeyMan` to actually use for those things. This cache is used exclusively and we no longer iterate the SPKMs.
Also added a benchmark for `IsMine`.

After TopUp completes, the wallet containing each SPKM will want to know
what new scriptPubKeys were generated. In order for all TopUp calls
(including ones internal the the SPKM), we use a callback function in
the WalletStorage interface.

The wallet decryption process (CheckDecryptionKey() and Unlock())
contains an arg 'accept_no_keys,' introduced in #13926, that has
never been used.
Additionally, this also removes the unimplemented SplitWalletPath
function.

that guards it
`CWallet::GetEncryptionKey()` would return a reference to the internal
`CWallet::vMasterKey`, guarded by `CWallet::cs_wallet`, which is unsafe.
Returning a copy would be a shorter solution, but could have security
implications of the master key remaining somewhere in the memory even
after `CWallet::Lock()` (the current calls to
`CWallet::GetEncryptionKey()` are safe, but that is not future proof).
So, instead of `EncryptSecret(m_storage.GetEncryptionKey(), ...)`
change the `GetEncryptionKey()` method to provide the encryption
key to a given callback:
`m_storage.WithEncryptionKey([](const CKeyingMaterial& k) { EncryptSecret(k, ...); })`
This silences the following (clang 18):
```
wallet/wallet.cpp:3520:12: error: returning variable 'vMasterKey' by reference requires holding mutex 'cs_wallet' [-Werror,-Wthread-safety-reference-return]
3520 | return vMasterKey;
| ^
```
|
|
|
|
Making the `GenerateRandomKey` helper available to other modules via
key.{h.cpp} allows us to create random private keys directly at
instantiation of CKey, in contrast to the two-step process of creating
the instance and then having to call `MakeNewKey(...)`.

Pull request description:
Fixing #28897.
As the user may have imported a descriptor with a timestamp newer
than the actual birth time of the first key (by setting 'timestamp=now'),
the wallet needs to update the birth time when it detects a transaction
older than the oldest descriptor timestamp.
Testing Notes:
Can cherry-pick the test commit on top of master. It will fail there.

|

To avoid scanning blocks, as assumed by a wallet with no
generated keys or imported scripts, the default value for
the birth time needs to be set to the maximum int64_t value.
Once the first key is generated or the first script is imported,
the legacy SPKM will update the birth time automatically.

Right now a wallet descriptor is converted to it's string representation
(via `Descriptor::ToString`) repeatedly at different instances:
- on finding a `DescriptorScriptPubKeyMan` for a given descriptor
(`CWallet::GetDescriptorScriptPubKeyMan`, e.g. used by the
`importdescriptors` RPC); the string representation is created once
for each spkm in the wallet and at each iteration again for
the searched descriptor (`DescriptorScriptPubKeyMan::HasWalletDescriptor`)
- whenever `DescriptorScriptPubKeyMan::GetID()` is called, e.g. in
`TopUp` or any instances where a descriptor is written to the DB
to determine the database key etc.
As there is no good reason to calculate a fixed descriptor's string/ID
more than once, add the ID as a field to `WalletDescriptor` and
calculate it immediately at initialization (or deserialization).
`HasWalletDescriptor` is changed to compare the spkm's and searched
descriptor's ID instead of the string to take use of that.
This speeds up the functional test `wallet_miniscript.py` by a factor of
5-6x on my machine (3m30.95s on master vs. 0m38.02s on PR). The recently
introduced "max-size TapMiniscript" test-case introduced a descriptor
that takes 2-3 seconds to create a string representation, so the
repeated calls to that were significantly hurting the performance.

1de8a2372ab39386e689b27d15c4d029be239319 wallet: disallow migration of invalid or not-watched scripts (furszy)
Pull request description:
Fixing #28057.
The legacy wallet allows to import any raw script (#28126), without
checking if it was valid or not. Appending it to the watch-only set.
This causes a crash in the migration process because we are only
expecting to find valid scripts inside the legacy spkm.
These stored scripts internally map to `ISMINE_NO` (same as if they
weren't stored at all..).
So we need to check for these special case, and take into account that
the legacy spkm could be storing invalid not watched scripts.
Which, in code words, means `IsMineInner()` returning
`IsMineResult::INVALID` for them.
Note:
To verify this, can run the test commit on top of master.
`wallet_migration.py` will crash without the bugfix commit.

This allows us to verify the descriptor ID on the descriptors
unit tests in different software versions without requiring to
use the entire DescriptorScriptPubKeyMan machinery.
Note:
The unit test changes are introduced after the bugfix commit
but this commit + the unit test commit can be cherry-picked
on top of the v25 branch to verify IDs correctness. IDs must
be the same for v25 and after the bugfix commit.

e9379f1ffa7a4eebce397f1150317e840655e021 rpc, wallet: Include information about blank flag (Andrew Chow)
Pull request description:
The `blank` wallet flag is used to indicate that the wallet intentionally does not have any keys, scripts, or descriptors, and it prevents the automatic generation of those things for such a wallet. Once the wallet contains any of those data, it is unnecessary, and possibly incorrect, to have `blank` set. This PR fixes a few places where this was not properly happening. It also adds a test for this unset behavior.

To avoid wasting processing power, we can skip blocks that occurred
before the wallet's creation time, since these blocks are guaranteed
not to contain any relevant wallet data.
This has direct implications (an speed improvement) on the underlying
blockchain synchronization process as well.
The reason is that the validation interface queue is limited to
10 tasks per time. This means that no more than 10 blocks can be
waiting for the wallet(s) to be processed while we are synchronizing
the chain (activating the best chain to be more precise).
Which can be a bottleneck if blocks arrive and are processed faster
from the network than what they are processed by the wallet(s).

bd13dc2f46ea10302a928fcf0f53b7aed77ad260 Switch hardened derivation marker to h in descriptors (Sjors Provoost)
Pull request description:
This makes it easier to handle descriptor strings manually, especially when importing from another Bitcoin Core wallet.
For example the `importdescriptors` RPC call is easiest to use `h` as the marker: `'["desc": ".../0h/..."]'`, avoiding the need for escape characters. With this change `listdescriptors` will use `h`, so you can copy-paste the result, without having to add escape characters or switch `'` to 'h' manually.
Both markers can still be parsed.
The `hdkeypath` field in `getaddressinfo` is also impacted by this change, except for legacy wallets. The latter is to prevent accidentally breaking ancient software that uses our legacy wallet.

This makes it easier to handle descriptor strings manually. E.g. an RPC call that takes an array of descriptors can now use '["desc": ".../0h/..."]'.
Both markers can still be parsed. The default for new descriptors is changed to h. In normalized form h is also used. For private keys the chosen marker is preserved in a round trip.
The hdkeypath field in getaddressinfo is also impacted by this change.

599ff5adfc7e1227c6d97d861d0715aee57611dd wallet: avoid double TopUp() calls on descriptor wallets (furszy)
Pull request description:
Found it while was digging over a `getnewaddress` timeout on the functional test suite.
### Context:
We are calling `TopUp()` twice in the following flows for descriptor wallets:
A) `CWallet::GetNewDestination`:
1) Calls spk_man->TopUp()
2) Calls spk_man->GetNewDestination() --> which, after the basic script checks, calls TopUp() again.
B) `CWallet::GetReservedDestination`:
1) Calls spk_man->TopUp()
2) Calls spk_man->GetReservedDestination() --> which calls to GetNewDestination (which calls to TopUp again).
### Changes:
Move `TopUp()` responsibility from the wallet class to each scriptpubkeyman.
So each spkm can decide to call it or not after perform the basic checks
for the new destination request.
Aside from that, remove the unused `nAccountingEntryNumber` wallet field. And a duplicated descriptor type check in `GetNewDestination`

* Remove redundant, hard-to-read code by adding a new `OutputType` and adding shuffle, erase, and push_back methods for `CoinsResult`
* Add missing `BOOST_ASSERT` to unit test
* Ensure functional test only runs if using descriptor wallets
* Improve readability of `AttemptSelection` by removing triple-nested if statement
Note for reviewers: commit `refactor: add new helper methods` should throw an "unused function warning"; the function is used in the next commit. Also, commit `wallet: switch to new shuffle, erase, push_back` will fail to compile, but this is fixed in the next commit with a scripted-diff. the commits are separate like this (code change then scripted-diff) to improve legibility.
