fe5d22bc67 More concise conversion of CDataStream to string (Glenn Willen)

Pull request description:

  As discussed in the comments on #14473, I think that bug was caused primarily by failure to adhere to the invariant that a PSBTInput always has exactly one of the two utxo fields present -- an invariant that is already enforced by PSBTInput::IsSane, but which we were temporarily suspending during signing.

  This refactor repairs the invariant, also fixing the bug. It also simplifies some other code, and removes redundant parameters from some related functions.

  fixes #14473

rpc: Include rpc/util.h where needed for RPCHelpMan
Just a preparatory commit to add the header to the includes and run
clang-format to sort the include lists.

Splitting this up into a separate commit makes future scripted-diffs
easier.

Pull request description:

  This creates an incomplete [`Chain`](https://github.com/ryanofsky/bitcoin/blob/pr/wipc-sep/src/interfaces/chain.h) interface in [`src/interfaces/`](https://github.com/ryanofsky/bitcoin/tree/pr/wipc-sep/src/interfaces) and begins to update wallet code to use it.

  #10973 builds on this, changing the wallet to use the new interface to access chain state, instead of using CBlockIndex pointers and global variables like `chainActive`.

Glenn Willen 0f5bda2bd9 Simplify arguments to SignPSBTInput
Remove redundant arguments to SignPSBTInput -- since it needs several
bits of the PartiallySignedTransaction, pass in a reference instead of
doing it piecemeal. This saves us having to pass in both a PSBTInput and
its index, as well as having to pass in the CTransaction. Also avoid
redundantly passing the sighash_type, which is contained in the
PSBTInput already.

Merge #13424: Consistently validate txid / blockhash length and encoding in rpc calls
5eb20f81d9 Consistently use ParseHashV to validate hash inputs in rpc (Ben Woosley)

Pull request description:

  ParseHashV validates the length and encoding of the string and throws
  an informative RPC error on failure, which is as good or better than
  these alternative calls.

  Note I switched ParseHashV to check string length first, because
  IsHex tests that the length is even, and an error like:
  "must be of length 64 (not 63, for X)" is much more informative than
  "must be hexadecimal string (not X)" in that case.

  Split from #13420

  This PR adds "key origin" (master fingeprint + key path) information to what is exposed from `SigningProvider`s, allowing this information to be used by the generic PSBT code instead of having the RPC pull it directly from the wallet.

  This is also a preparation to having PSBT interact with output descriptors, which can then directly expose key origin information for the scripts they generate.

Pull request description:

  This Pull Request fully implements the [updated](https://github.com/bitcoin/bips/pull/694) BIP 174 specification. It is based upon #13425 which implements the majority of the signing logic.

  BIP 174 specifies a binary transaction format which contains the information necessary for a signer to produce signatures for the transaction and holds the signatures for an input while the input does not have a complete set of signatures.

  This PR contains structs for PSBT, serialization, and deserialzation code. Some changes to `SignatureData` have been made to support detection of UTXO type and storing public keys.

  ***

  Many RPCs have been added to handle PSBTs.

  `walletprocesspsbt` takes a PSBT format transaction, updates the PSBT with any inputs related to this wallet, signs, and finalizes the transaction. There is also an option to not sign and just update.

  `walletcreatefundedpsbt` creates a PSBT from user provided data in the same form as createrawtransaction. It also funds the transaction and takes an options argument in the same form as `fundrawtransaction`. The resulting PSBT is blank with no input or output data filled in. It is analogous to a combination of `createrawtransaction` and `fundrawtransaction`

  `decodepsbt` takes a PSBT and decodes it to JSON. It is analogous to `decoderawtransaction`

  `combinepsbt` takes multiple PSBTs for the same tx and combines them. It is analogous to `combinerawtransaction`

  `finalizepsbt` takes a PSBT and finalizes the inputs. If all inputs are final, it extracts the network serialized transaction and returns that instead of a PSBT unless instructed otherwise.

  `createpsbt` is like `createrawtransaction` but for PSBTs instead of raw transactions.

  `convertpsbt` takes a network serialized transaction and converts it into a psbt. The resulting psbt will lose all signature data and an explicit flag must be set to allow transactions with signature data to be converted.

  ***

  This supersedes #12136

Pull request description:

  Signatures using segregated witness commit to the amount being spent, so that value must be passed into signrawtransactionwithkey and signrawtransactionwithwallet. This ensures an error is issued if that doesn't happen, rather than just assuming the value is 0 and producing a signature that is almost certainly invalid.

d280617bf5 [qa] Add a test for merkle proof malleation (Suhas Daftuar)
ed82f17000 have verifytxoutproof check the number of txns in proof structure (Gregory Sanders)

Pull request description:

  Recent publication of a weakness in Bitcoin's merkle tree construction demonstrates many SPV applications vulnerable to an expensive to pull off yet still plausible attack: https://bitslog.wordpress.com/2018/06/09/leaf-node-weakness-in-bitcoin-merkle-tree-design/

  This change would at least allow `verifytxoutproof` to properly validate that the proof matches a known block, with known number of transactions any time after the full block is processed. This should neuter the attack entirely.

  The negative is that a header-only processed block/future syncing mode would cause this to fail until the node has imported the data required.

Merge #13425: Moving final scriptSig construction from CombineSignatures to ProduceSignature (PSBT signer logic)
b81560029 Remove CombineSignatures and replace tests (Andrew Chow)
ed94c8b55 Replace CombineSignatures with ProduceSignature (Andrew Chow)
0422beb9b Make SignatureData able to store signatures and scripts (Andrew Chow)
b6edb4f5e Inline Sign1 and SignN (Andrew Chow)

Pull request description:

  Currently CombineSignatures is used to create the final scriptSig or an input. However ProduceSignature is capable of doing this itself. Using both CombineSignatures and ProduceSignature results in code duplication which is unnecessary.

  To move the scriptSig construction to ProduceSignatures, the SignatureData class contains two maps to hold pubkeys mapped to signatures, and script ids mapped to scripts. DataFromTransaction is extended to be able to extract signatures, their public keys, and scripts from existing ScriptSigs.

  The SignaureData are then passed down to SignStep which can use the aforementioned maps to get the signatures, pubkeys, and scripts that it needs, falling back to the actual SigningProvider and SignatureCreator if the data are not available in the SignatureData.

  Additionally, Sign1 and SignN have been removed and their functionality inlined into SignStep since Sign1 is really just a wrapper around CreateSig.

  Since ProduceSignature can produce the final scriptSig or scriptWitness by using SignatureData which has extracted data from the transaction, CombineSignatures is unnecessary as ProduceSignature is able to replicate all of CombineSignatures' functionality.

  This also furthers BIP 174 support and begins moving towards a BIP 174 style backend.

  The tests have also been updated to use the new combining methodology.

Andrew Chow ed94c8b556 Replace CombineSignatures with ProduceSignature
Instead of using CombineSignatures to create the final scriptSig or
scriptWitness of an input, use ProduceSignature itself.

To allow for ProduceSignature to place signatures, pubkeys, and scripts
that it does not know about, we pass down the SignatureData to SignStep
which pulls out the information that it needs from the SignatureData.

Andrew Chow 0422beb9bd Make SignatureData able to store signatures and scripts
In addition to having the scriptSig and scriptWitness, have SignatureData
also be able to store just the signatures (pubkeys mapped to sigs) and
scripts (script ids mapped to scripts).

Also have DataFromTransaction be able to extract signatures and scripts
from the scriptSig and scriptWitness of an input to put them in SignatureData.

Adds a new SignatureChecker which takes a SignatureData and puts pubkeys
and signatures into it when it successfully verifies a signature.

Adds a new field in SignatureData which stores whether the SignatureData
was complete. This allows us to also update the scriptSig and
scriptWitness to the final one when updating a SignatureData with another
one.

Pull request description:

  * Removes the `m_provider` field from `BaseSignatureCreator`. Instead both a `SigningProvider` (which provides keys and scripts) and a `BaseSignatureCreator` (which implements the transaction-specific (or other) signing logic) are passed into and down in `ProduceSignature`, making the two concepts orthogonal.
  * Makes `BaseSignatureCreator` a pure interface without constructor, making it easier to implement new derivations of it (for example for message signing).
  * As `DummySignatureCreator` now becomes a stateless object, turn it into a singleton `DUMMY_SIGNATURE_CREATOR`.

Pull request description:

  The second parameter of the `createrawtransaction` is a dictionary of the outputs. This comes with at least two drawbacks:

  * In case of duplicate keys, either of them might silently disappear, with no user feedback at all. A user needs to make other mistakes, but this could eventually lead to abnormal tx fees.
  * A dictionary does not guarantee that keys are sorted. Again, a user needs to keep this in mind, as it could eventually lead to excessive tx fees.

  Even though my scenario of loss-of-funds is unlikely to happen, I see it as a inconvenience that should be fixed.

  This is a quick fix for #12418, which is a regression in 0.16.

  It permits specifying just the inner redeemscript to let `signrawtransaction` succeed. This inner redeemscript is already reported by `addmultisigaddress` & co.

  #11708 uses a different approach, where `listunspent` reports both inner & outer redeemscript, but requires both to be provided to `signrawtransaction`. Part of #11708 is still needed even in combination with this PR however, as currently the inner redeemscript isn't reported by `listunspent`.

Pull request description:

  First commit just removes default arguments from `AcceptToMemoryPool` and consolidates two arguments, it does not change behavior.

  Second commit finally fixes the fact that we're not meant to reject based on mempool min fee when adding a transaction from a disconnected block during a reorg as mentioned [here](https://github.com/bitcoin/bitcoin/pull/9602#issue-202197849)

  Third commit makes fee estimation ignore transactions added from a disconnected block during a reorg. I think this was another source of fee estimates returning estimates below 1000 sat/kB as in #11303.

Pieter Wuille 5c8ff0d448 Introduce wrappers around CBitcoinAddress
This patch removes the need for the intermediary Base58 type
CBitcoinAddress, by providing {Encode,Decode,IsValid}Destination
function that directly operate on the conversion between strings

Andrew Chow ec6902d0ea rpc: Push down safe mode checks
This contains most of the changes of 10563 "remove safe mode", but doesn't
remove the safe mode yet, but put an `ObserveSafeMode()` check in
individual calls with okSafeMode=false.

This cleans up the ugly "okSafeMode" flag from the dispatch tables,
which is not a concern for the RPC server.

Merge #11050: Avoid treating null RPC arguments different from missing arguments
745d2e3 Clean up getbalance RPC parameter handling (Russell Yanofsky)
fd5d71e Update developer notes after params.size() cleanup (Russell Yanofsky)
e067673 Avoid treating null RPC arguments different from missing arguments (Russell Yanofsky)
e666efc Get rid of redundant RPC params.size() checks (Russell Yanofsky)

Pull request description:

  This is a followup to #10783.

  - The first commit doesn't change behavior at all, just simplifies code.
  - The second commit just changes RPC methods to treat null arguments the same as missing arguments instead of throwing type errors.
  - The third commit updates developer notes after the cleanup.
  - The forth commit does some additional code cleanup in `getbalance`.

  Followup changes that should happen in future PRs:

  - [ ] Replace uses of `.isTrue()` with calls to `.get_bool()` so numbers, objects, and strings cause type errors instead of being interpreted as false. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133850525
  - [ ] Add braces around if statements. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133851133
  - [ ] Maybe improve UniValue type error exceptions and eliminate RPCTypeCheck and RPCTypeCheckArgument functions. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133829303

Merge #11027: [RPC] Only return hex field once in getrawtransaction
6bbdafc Pass serialization flags and whether to include hex to TxToUniv (Andrew Chow)
e029c6e Only return hex field once in getrawtransaction (Andrew Chow)

Pull request description:

  The hex is already returned in `TxToUniv()`, no need to give it out a second time in getrawtransaction itself.

Russell Yanofsky e067673f4e Avoid treating null RPC arguments different from missing arguments
This changes RPC methods to treat null arguments the same as missing arguments,
instead of throwing type errors. Specifically:

- `getbalance` method now returns the wallet balance when the `account` param
  is null instead of throwing a type error (same as when parameter is missing).
  It is still an error to supply `minconf` or `watchonly` options when the
  account is null.

- `addnode` and `setban` methods now return help text instead of type errors if
  `command` params are null (same as when params are missing).

- `sendrawtransaction`, `setaccount`, `movecmd`, `sendfrom`,
  `addmultisigaddress`, `listaccounts`, `lockunspent` methods accept null
  default values where missing values were previously allowed, and treat them
  the same.
