f76733eda5 Cache the immediate derivation parent xpub
If unhardened derivation is used, cache the immediate derivation
parent xpub and use it for unhardened derivation

58f54b686f Add DescriptorCache* read_cache and DescriptorCache* write_cache to Expand and GetPubKey
Have Expand, ExpandFromCache, and ExpandHelper take additional DescriptorCache
parameters. These are then passed into PubkeyProvider::GetPubKey which
also takes them as arguments.

Reading and writing to the cache is pushed down into GetPubKey. The old cache where
pubkeys are serialized to a vector is completely removed and instead xpubs are being
cached in DescriptorCache.

Merge #17264: rpc: set default bip32derivs to true for psbt methods
5bad7921d0 [test] PSBT RPC: check that bip32_derivs are present by default (Sjors Provoost)
29a21c9061 [rpc] set default bip32derivs to true for psbt methods (Sjors Provoost)

Pull request description:

  In https://github.com/bitcoin/bitcoin/pull/13557#pullrequestreview-135905054 I recommended not including bip32 deriviation by default in PSBTs:

  > _Bit of a privacy issue_: let's say person A and B are about to spend from a multisig address, sending everything to person A. Person A gives their address to person B, their wallet wallet creates a PSBT, but doesn't sign it. Wallet A then calls `walletprocesspsbt` which signs it and _spontaneously adds the master_fingerprint and bip32 path_. Same issue with `walletcreatefundedpsbt`.
  >
  > Adding `bip32_derivs` should probably be opt-in.

  In practice I find this default quite annoying because I forget it and end up with a confused hardware wallet.

  More importantly, in the multisig example I provided, it's actually essential for the other side to know the derivation details (in addition to an xpub). This allows them to check that change is going to an address you can still co-sign for (because the spending policy is unchanged except for an index).

Merge #18034: Get the OutputType for a descriptor
7e80f646b2 Get the OutputType for a descriptor (Andrew Chow)

Pull request description:

  Adds a `GetOutputType()` method to get the OutputType of a descriptor. Some descriptors don't have a determinate OutputType, so we actually use an `Optional<OutputType>`. For descriptors with indeterminate OutputType, we return `nullopt`.

  `addr()` and `raw()` use OutputTypes as determined by the CTxDestination they have. For simplicity, `ScriptHash` destinations are `LEGACY` even though they could be `P2SH_SEGWIT`.
  `combo()`, `pk()`, and `multi()` are `nullopt` as they either don't have an OutputType or they have multiple. `DescriptorImpl` defaults to `nullopt`.
  `pkh()` is `LEGACY` as expected
  `wpkh()` and `wsh()` are `BECH32` as expected.
  `sh()` checks whether the sub-descriptor is `BECH32`. If so, it is `P2SH_SEGWIT`. Otherwise it is `LEGACY`.

  The descriptor tests are updated to check the OutputType too.

7f1475c711 rpc: update validateaddress RPCExamples to bech32 (Sebastian Falbesoner)

Pull request description:

  Another small step to get rid of legacy addresses in the RPC help texts and by that encourage the use of bech32 addresses by default. The (invalid) address is the same as in the `getaddressinfo` RPC (see 2ee0cb3330, kudos to jonatack!), I don't think it adds any value to have a different example address per RPC.

Merge #18067: wallet: Improve LegacyScriptPubKeyMan::CanProvide script recognition
a304a3632f Revert "Store p2sh scripts in AddAndGetDestinationForScript" (Russell Yanofsky)
eb7d8a5b07 [test] check for addmultisigaddress regression (Sjors Provoost)
005f8a92cc wallet: Improve LegacyScriptPubKeyMan::CanProvide script recognition (Russell Yanofsky)

Pull request description:

  Make `LegacyScriptPubKeyMan::CanProvide` method able to recognize p2sh scripts when the redeem script is present in the `mapScripts` map without the p2sh script also having to be added to the `mapScripts` map. This restores behavior prior to #17261, which I think broke backwards compatibility with old wallet files by no longer treating addresses created by `addmultisigaddress` calls before #17261 as solvable.

  The reason why tests didn't fail with the CanProvide implementation in #17261 is because of a workaround added in 4a7e43e846 "Store p2sh scripts in AddAndGetDestinationForScript", which masked the problem for new `addmultisigaddress` RPC calls without fixing it for multisig addresses already created in old wallet files.

  This change adds a lot of comments and allows reverting commit 4a7e43e846 "Store p2sh scripts in AddAndGetDestinationForScript", so the `AddAndGetDestinationForScript()` function, `CanProvide()` method, and `mapScripts` map should all be more comprehensible

  It adds a `MockForward` method to the scheduler class that iterates through the task queue and reschedules them to be `delta_seconds` sooner.

Merge #18123: gui: Fix race in WalletModel::pollBalanceChanged
bf36a3ccc2 gui: Fix race in WalletModel::pollBalanceChanged (Russell Yanofsky)

Pull request description:

  Poll function was wrongly setting cached height to the current chain height instead of the chain height at the time of polling.

  This bug could cause balances to appear out of date, and was first introduced a0704a8996 (diff-2e3836af182cfb375329c3463ffd91f8L117). Before that commit, there wasn't a problem because cs_main was held during the poll update.

  Currently, the problem should be rare. But if 8937d99ce81a27ae5e1012a28323c0e26d89c50b from #17954 were merged, the problem would get worse, because the wrong cachedNumBlocks value would be set if the wallet was polled in the interval between a block being connected and it processing the BlockConnected notification.

  MarcoFalke also points out that a0704a8996 could lead to GUI hangs as well, because previously the pollBalanceChanged method, which runs on the GUI thread, would only make a nonblocking TRY_LOCK(cs_main) call, but after could make blocking LOCK(cs_main) calls, potentially locking up the GUI.

  Thanks to John Newbery for finding this bug this while reviewing https://github.com/bitcoin/bitcoin/pull/17954.

  Ensure prevector data is appropriately aligned. Earlier discussion in #17530.

  **Edit laanwj**: In contrast to #17530, it does this without increase in size of any of the coin cache data structures (x86_64, clang)

005f8a92cc wallet: Improve LegacyScriptPubKeyMan::CanProvide script recognition
Make LegacyScriptPubKeyMan::CanProvide method able to recognize p2sh scripts
when the redeem script is present in the mapScripts map without the p2sh script
also having to be added to the mapScripts map. This restores behavior prior to
https://github.com/bitcoin/bitcoin/pull/17261, which I think broke backwards
compatibility with old wallet files by no longer treating addresses created by
`addmultisigaddress` calls before #17261 as solvable.

The reason why tests didn't fail with the CanProvide implementation in #17261
is because of a workaround added in 4a7e43e846
"Store p2sh scripts in AddAndGetDestinationForScript", which masked the problem
for new `addmultisigaddress` RPC calls without fixing it for multisig addresses
already created in old wallet files.

This change adds a lot of comments and allows reverting commit
4a7e43e846 "Store p2sh scripts in
AddAndGetDestinationForScript", so the AddAndGetDestinationForScript() function,
CanProvide() method, and mapScripts map should all be more comprehensible

  The next step of changes from #10785.

  This one adds:
  * A meta-formatter for vectors, which serializes the vector elements using another formatter
  * Switch the undo.h code to the new framework, using the above (where undo entries are serialized as a vector, each of which uses a modified serializer for the UTXOs).

Merge #18101: qt: Fix deprecated QCharRef usage
ac57859e53 qt: Fix deprecated QCharRef usage (Hennadii Stepanov)

Pull request description:

  From Qt docs:
  - [`QKeyEvent::text()`](https://doc.qt.io/qt-5/qkeyevent.html#text):
  > Return values when modifier keys such as Shift, Control, Alt, and Meta are pressed differ among platforms and could return an empty string.

  - [`QString::operator[]()`](https://doc.qt.io/qt-5/qstring.html#operator-5b-5d):

  > **Note:** Before Qt 5.14 it was possible to use this operator to access a character at an out-of-bounds position in the string, and then assign to such a position, causing the string to be automatically resized. Furthermore, assigning a value to the returned `QCharRef` would cause a detach of the string, even if the string has been copied in the meanwhile (and the `QCharRef` kept alive while the copy was taken). These behaviors are deprecated, and will be changed in a future version of Qt.

  Since Qt 5.14 this causes a `QCharRef` warning if any modifier key is pressed while the splashscreen is still displayed.

  Fix #18080.

  Note: Ctrl+Q will also close the spashscreen now.

Pull request description:

  Fixes #18090

  We currently don't pass `clientmodel` changes from the `walletframe` to the `walletviews` leading to possible invalid access during shutdown because all walletviews miss the nullifying of the clientmodel.
