b9ee63c71b751fd67da777774ea8c0b27e7db2f8 Make descriptor test deterministic (David Reikher) Pull request description: This is an improvement to a test, inspired by #14343 - removing non determinism from a test. The test `descriptor_test` is non-deterministic, as it relies on the `MaybeUseHInsteadOfApostrophy` function which randomly either swaps all apostrophes with 'h' or doesn't at all in a descriptor. This fix makes both cases always run, if an apostrophe is found in a test descriptor. This does not reduce test coverage but removes the non-determinism. Additionally, the `MaybeUseHInsteadOfApostrophy` function removed the checksum if found at the end of a descriptor when the apostrophes are swapped by 'h's, since after being swapped the checksum is no longer correct. I instead added re-calculation of the checksum using the `DescriptorChecksum` function, which adds coverage for the case of a descriptors having 'h's instead of apostrophes and a checksum. This was previously lacking. To achieve this I had to move `DescriptorChecksum` and `PolyMod` out of the anonymous namespace in descriptor.cpp to make `DescriptorChecksum` accessible in descriptor_tests.cpp. All tests complete successfully (functional as well as unit tests).

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 and useful hints for developers can be found in doc/developer-notes.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.
