26fe9b990995f9cb5eee21d40b4daaad19f7181f Add support for descriptors to utxoupdatepsbt (Pieter Wuille) 3135c1a2d2e2fb31bc362c848bd2456d576e408b Abstract out UpdatePSBTOutput from FillPSBT (Pieter Wuille) fb90ec3c33e824f5abb6a68452c683d6ce8b3e4a Abstract out EvalDescriptorStringOrObject from scantxoutset (Pieter Wuille) eaf4f887348a08c620732125ad4430e1a133d434 Abstract out IsSegWitOutput from utxoupdatepsbt (Pieter Wuille) Pull request description: This adds a descriptors argument to the `utxoupdatepsbt` RPC. This means: * Input and output scripts and keys will be filled in when known. * P2SH-witness inputs will be filled in from the UTXO set when a descriptor is provided that shows they're spending segwit outputs. This also moves some (newly) shared code to separate functions: `UpdatePSBTOutput` (an analogue to `SignPSBTInput`), `IsSegWitOutput`, and `EvalDescriptorStringOrObject` (implementing the string or object notation parsing used in `scantxoutset`).

This improves privacy, as a payer could otherwise begin tracking a payee's wallet by regularly peppering a known UTXO with dust outputs, which would then be scooped up and used in payments by the payee, allowing the payer to map out (1) the inputs owned by the payee and (2) the destinations to which the payee is making payments. This replaces #10386 and together with the (now merged) #12257 it addresses #10065 in full. The concerns raised in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381 are also addressed due to #12257. ~~Note: this builds on top of #15780.~~ (merged) ACKs for commit 5ebc6b: jnewbery: ACK 5ebc6b0eb laanwj: Concept and code-review ACK 5ebc6b0eb267e0552c66fffc5e5afe7df8becf80 meshcollider: Code review ACK https://github.com/bitcoin/bitcoin/pull/13756/commits/5ebc6b0eb267e0552c66fffc5e5afe7df8becf80 achow101: ACK 5ebc6b0eb267e0552c66fffc5e5afe7df8becf80 modulo above nits Tree-SHA512: fdef45826af544cbbb45634ac367852cc467ec87081d86d08b53ca849e588617e9a0a255b7e7bb28692d15332de58d6c3d274ac003355220e4213d7d9070742e

But the private key for a specific index is not given. This allows private keys for specific indices to be derived. This also allows those keys to be imported through the `importmulti` RPC rather than having to provide them separately.

Descriptors may optionally be suffixed with a `#` plus these 8 checksum characters. Any descriptor that contains a `#` at the end must be followed by a valid checksum. If the `#` is missing entirely, it is valid without checksum. All RPCs are updated to report descriptors that include the checksum. On input, they are optional except in `deriveaddress` and `importmulti`, which require descriptors which include a checksum. A new RPC is also added to analyse descriptors (`getdescriptorinfo`), which can be used to compute the checksum for a descriptor without.

It only works with witness UTXOs because full transactions (as would be needed for non-witness UTXOs) are not available unless txindex is enabled. `joinpsbts` joins the inputs from multiple distinct PSBTs into one PSBT. e.g. if PSBT 1 has inputs 1 and 2, and PSBT 2 has inputs 3 and 4, `joinpsbts` would create a new PSBT with inputs 1, 2, 3, and 4. `analyzepsbt` analyzes a PSBT and determines the current state of it and all of its inputs, and the next step that needs to be done.

The feature is exposed in `listunspent`, `getaddressinfo`, and `scantxoutset` whenever these calls are applied to solvable outputs/addresses. This is not very useful on its own, though when we add RPCs to import descriptors, or sign PSBTs using descriptors, these strings become a compact and standalone way of conveying everything necessary to sign an output (excluding private keys). Unit tests and rudimentary RPC tests are included (more relevant tests can be added once RPCs support descriptors). Fixes #14503.

2018-11-01Refactor PSBTInput signing to enforce invariantGlenn Willen
Refactor the process of PSBTInput signing to enforce the invariant that a PSBTInput always has _either_ a witness_utxo or a non_witness_utxo, never both. This simplifies the logic of SignPSBTInput slightly, since it no longer has to deal with the "both" case. When calling it, we now give it, in order of preference: (1) whichever of the utxo fields was already present in the PSBT we received, or (2) if neither, the non_witness_utxo field, which is just a copy of the input transaction, which we get from the wallet. SignPSBTInput no longer has to remove one of the two fields; instead, it will check if we have a witness signature, and if so, it will replace the non_witness_utxo with the witness_utxo (which is smaller, as it is just a copy of the output being spent.) Add PSBTInput::IsSane checks in two more places, which checks for both utxo fields being present; we will now give an RPC error early on if we are supplied such a malformed PSBT to fill in. Also add a check to FillPSBT, to avoid touching any input that is already signed. (This is now redundant, since we should no longer potentially harm an already-signed input, but it's harmless.) fixes #14473
2018-11-01Simplify arguments to SignPSBTInputGlenn Willen
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.
2018-11-01Add bool PSBTInputSignedGlenn Willen
Refactor out a "PSBTInputSigned" function to check if a PSBT is signed, for use in subsequent commits. Also improve a related comment.
2018-11-01New PartiallySignedTransaction constructor from CTransctionGlenn Willen
New constructor that creates a PartiallySignedTransaction from a CTransaction, automatically sizing the inputs and outputs vectors for convenience.
2018-11-01Avoid using numeric_limits for sequence numbers and lock timesRussell Yanofsky
Switches to named constants, because numeric_limits calls can be harder to read and less portable. Change was suggested by James O'Beirne <james.obeirne@gmail.com> in https://github.com/bitcoin/bitcoin/pull/10973#discussion_r213473620 There are no changes in behavior except on some platforms we don't support (ILP64, IP16L32, I16LP32), where SignalsOptInRBF() and MutateTxAddInput() functions would now work correctly.
2018-11-01Merge #14377: check that a separator is found for psbt inputs, outputs, and ↵Wladimir J. van der Laan
global map 4fb3388db95f408566e43ebb9736842cfbff0a7d check that a separator is found for psbt inputs, outputs, and global map (Andrew Chow) Pull request description: Currently it doesn't make sure that a separator was found so PSBTs missing a trailing separator would still pass. This fixes that and adds a test case for it. It really only makes sense to check for the separator for the output maps as if an input or global map was missing a separator, the fields following it would be interpreted as belonging to the previous input or global map. However I have added the check for those two anyways to be consistent.
