CheckInputScripts f63dec189c3c8eee1ab2187681d5d0b2513b1b2e [REFACTOR] Initialize PrecomputedTransactionData in CheckInputScripts (Pieter Wuille) Pull request description: This is a single commit taken from the Schnorr/Taproot PR #17977. Add a default constructor to `PrecomputedTransactionData`, which doesn't initialize the struct's members. Instead they're initialized inside the `CheckInputScripts()` function. This allows a later commit to add the spent UTXOs to that structure. The spent UTXOs are required for the schnorr signature hash, since it commits to the scriptPubKeys. See https://github.com/bitcoin/bips/blob/master/bip-0341.mediawiki#common-signature-message for details. By itself, this isn't really an improvement to the code, but I think it makes sense to separate out the refactor/moveonly commits from PR #17977 so that PR is only the logical changes needed for Schnorr/Taproot.

2b0fcff7f26d59fed4bcafd1602325122a206c67 Make VerifyWitnessProgram use a Span stack (Pieter Wuille) Pull request description: Here is a follow-up to #18002, again with the goal of simplifying (potential) BIP341 code. Instead of passing a begin and end iterator of the initial stack to `ExecuteWitnessScript`, they are turned into a `Span<const valtype>`, representing a span of `valtype`s in memory. This allows `VerifyWitnessProgram` to operate on that span directly, instead of juggling iterators around (which would be exacerbated by #17977 if trying to avoid copying the stack).

This issue was also pointed out by Sergio Demian Lerner in https://bitslog.wordpress.com/2017/04/17/new-quadratic-delays-in-bitcoin-scripts/, and this PR implements a variant of the O(1) algorithm suggested there. This is not a problem currently, because even with a nesting depth of 100 (the maximum possible right now due to the 201 ops limit), the slowdown caused by this on my machine is around 70 ns per opcode (or 0.25 s per block) at worst, far lower than what is possible with other opcodes. This PR mostly serves as a proof of concept that it's possible to avoid it, which may be relevant in discussions around increasing the opcode limits in future script versions. Without it, the execution time of scripts can grow quadratically with the nesting depth, which very quickly becomes unreasonable. This improves upon #14245 by completely removing the `vfExec` vector.

Instead of serializing pubkeys and whatever else we would want to cache in a way that may not be backwards compatible, we instead create a `DescriptorCache` object and populate it. This object contains only an xpub cache. Since the only `PubkeyProvider` that used the cache is the `BIP32PubkeyProvider` we just have it store the xpubs instead of the pubkeys. This allows us to have both the parent xpub and the child xpubs in the same container. The map is keyed by `KeyOriginInfo`. Sine we are caching `CExtPubKey`s in `DescriptorCache`, `BIP32PubKeyProviders` can use the cached parent xpubs to derive the children if unhardened derivation is used in the last step. This also means that we can still derive the keys for a `BIP32PubkeyProvider` that has hardened derivation steps. When combined with descriptor wallets, this should allow us to be able to import a descriptor with an `xprv` and hardened steps and still be able to derive from it. In that sense, this is an alternative to #18163 To test that this works, the tests have been updated to do an additional `Expand` at the `i + 1` position. This expansion is not cached. We then do an `ExpandFromCache` at `i + 1` and use the cache that was produced by the expansion at `i`. This way, we won't have the child xpubs for `i + 1` but we will have the parent xpubs. So this checks whether the parent xpubs are being stored and can be used to derive the child keys. Descriptors that have a hardened last step are skipped for this part of the test because that will always require private keys.

Optimize Expand by having BIP32PubkeyProvider also cache the parent (or only) xpub within itself. Since Expand does not provide a read cache, it is useful to internally cache this xpub to avoid re-deriving the same xpub.
2020-03-07Only cache xpubs that have a hardened last stepAndrew Chow
Also adds tests for this: For ranged descriptors with unhardened derivation, we expect to find parent keys in the cache but no child keys. For descriptors containing an xpub but do not have unhardened derivation (i.e. hardened derivation or single xpub with or without derivation), we expect to find all of the keys in the cache, and the same number of keys in the cache as in the SigningProvider. For everything else (no xpub), nothing should be cached at all.

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.

2020-02-12wallet: Improve LegacyScriptPubKeyMan::CanProvide script recognitionRussell Yanofsky
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 4a7e43e8460127a40a7895519587399feff3b682 "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 4a7e43e8460127a40a7895519587399feff3b682 "Store p2sh scripts in AddAndGetDestinationForScript", so the AddAndGetDestinationForScript() function, CanProvide() method, and mapScripts map should all be more comprehensible

Moves around functions and things from CWallet into LegacyScriptPubKeyMan so that they are actually separate things without circular dependencies. *** Introducing the `ScriptPubKeyMan` (short for ScriptPubKeyManager) for managing scriptPubKeys and their associated scripts and keys. This functionality is moved over from `CWallet`. Instead, `CWallet` will have a pointer to a `ScriptPubKeyMan` for every possible address type, internal and external. It will fetch the correct `ScriptPubKeyMan` as necessary. When fetching new addresses, it chooses the `ScriptPubKeyMan` based on address type and whether it is change. For signing, it takes the script and asks each `ScriptPubKeyMan` for whether that `ScriptPubKeyMan` considers that script `IsMine`, whether it has that script, or whether it is able to produce a signature for it. If so, the `ScriptPubKeyMan` will provide a `SigningProvider` to the caller which will use that in order to sign. There is currently one `ScriptPubKeyMan` - the `LegacyScriptPubKeyMan`. Each `CWallet` will have only one `LegacyScriptPubKeyMan` with the pointers for all of the address types and change pointing to this `LegacyScriptPubKeyMan`. It is created when the wallet is loaded and all keys and metadata are loaded into it instead of `CWallet`. The `LegacyScriptPubKeyMan` is primarily made up of all of the key and script management that used to be in `CWallet`. For convenience, `CWallet` has a `GetLegacyScriptPubKeyMan` which will return the `LegacyScriptPubKeyMan` or a `nullptr` if it does not have one (not yet implemented, but callers will check for the `nullptr`). For purposes of signing, `LegacyScriptPubKeyMan`'s `GetSigningProvider` will return itself rather than a separate `SigningProvider`. This will be different for future `ScriptPubKeyMan`s. The `LegacyScriptPubKeyMan` will also handle the importing and exporting of keys and scripts instead of `CWallet`. As such, a number of RPCs have been limited to work only if a `LegacyScriptPubKeyMan` can be retrieved from the wallet. These RPCs are `sethdseed`, `addmultisigaddress`, `importaddress`, `importprivkey`, `importpubkey`, `importmulti`, `dumpprivkey`, and `dumpwallet`. Other RPCs which relied on the wallet for scripts and keys have been modified in order to take the `SigningProvider` retrieved from the `ScriptPubKeyMan` for a given script. Overall, these changes should not effect how everything actually works and the user should experience no difference between having this change and not having it. As such, no functional tests were changed, and the only unit tests changed were those that were directly accessing `CWallet` functions that have been removed. This PR is the last step in the [Wallet Structure Changes](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Class-Structure-Changes).
