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 |

Bitcoin Core integration/staging tree
What is Bitcoin?
Bitcoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Core is the name of open source software which enables the use of this currency.
For more information, as well as an immediately useable, binary version of the Bitcoin Core software, see https://bitcoincore.org/en/download/, or read the original whitepaper.
License
Bitcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.
Development Process
The master branch is regularly built and tested, but is not guaranteed to be
completely stable. Tags are created
regularly to indicate new official, stable release versions of Bitcoin Core.
The contribution workflow is described in CONTRIBUTING.md.
Testing
Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.
Automated Testing
Developers are strongly encouraged to write unit tests for new code, and to
submit new unit tests for old code. Unit tests can be compiled and run
(assuming they weren't disabled in configure) with: make check. Further details on running
and extending unit tests can be found in /src/test/README.md.
There are also regression and integration tests, written
in Python, that are run automatically on the build server.
These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py
The Travis CI system makes sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.
Manual Quality Assurance (QA) Testing
Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.
Translations
Changes to translations as well as new translations can be submitted to Bitcoin Core's Transifex page.
Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.
Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.
Translators should also subscribe to the mailing list.
