conversion. b301950df32443e358bc22ca22c6f9ac09d18219 Made expicit constructor CTransaction(const CMutableTransaction &tx). (lucash-dev) faf29dd019efef4b05e8e78885926764134d9c04 Minimal changes to comply with explicit CMutableTransaction -> CTranaction conversion. (lucash-dev) Pull request description: This PR is re-submission of #14156, which was automatically closed by github (glitch?) Original description: This PR makes explicit the now implicit conversion constructor `CTransaction(const CMutableTransaction&)` in `transaction.h`. Minimal changes were made elsewhere to make the code compilable. I'll follow up with other PRs to address individually refactoring functions that should have a `CMutableTransaction` version, or where a `CTransaction` should be reused. The rationale for this change is: - Conversion constructors should not be explicit unless there's a strong reason for it (in the opinion of, for example, https://google.github.io/styleguide/cppguide.html, and https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Ro-conversion. Let me know your take on this). - This particular conversion is very costly -- it implies a serialization plus hash of the transaction. - Even though `CTransaction` and `CMutableTransaction` represent the same data, they have very different use cases and performance properties. - Making it explicit allows for easier reasoning of performance trade-offs. - There has been previous performance issues caused by unneeded use of this implicit conversion. - This PR creates a map for places to look for possible refactoring and performance gains (this benefit still holds if the PR is not merged).

conversion. This commit makes the minimal changes necessary to fix compilation once CTransaction(const CMutableTransaction &tx) is made explicit. In each case an explicit call `CTransaction(...)` was added. Shouldn't affect behaviour or performance.

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.

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 Tree-SHA512: 1ac7a79e5bc669933f0a6fcc93ded55263fdde9e8c144a30266b13ef9f62aacf43edd4cbca1ffbe003090b067e9643c9298c79be69d7c1b10231b32acafb6338

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.

decodepsbt takes a PSBT and decodes it to JSON combinepsbt takes multiple PSBTs for the same tx and combines them. 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.

In preparation for more create transaction and fund transcation RPCs, refactor the transaction creation and funding logic into separate functions.

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.

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. related: #13451 `importprunedfunds` needs this check as well. Can expand it to cover this if people like the idea. Tree-SHA512: 0682ec2b622a38b29f3f635323e0a8b6fc071e8a6fd134c954579926ee7b516e642966bafa667016744ce49c16e19b24dbc8801f982a36ad0a6a4aff6d93f82b
2018-07-05Merge #13425: Moving final scriptSig construction from CombineSignatures to ↵Wladimir J. van der Laan
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.
