Pull request description:

  The `test/lint/lint-format-strings.py` was designed to count the number of format specifiers and assert that they are equal to the number of parameters passed to the format function. The goal seems reasonable, but the implementation has many problems:

  * It is written in Python, meaning that C++ code can not be parsed correctly. Currently it relies on brittle regex and string parsing.
  * Apart from the parsing errors, there are also many logic errors. For example, `count_format_specifiers` allows a mix of positional specifiers and non-positional specifiers, which can lead to runtime format bugs. Also, `count_format_specifiers` silently skipped over "special" format specifiers, which are valid in tinyformat, which again can lead to runtime format bugs being undetected.
  * The brittle logic has a history of breaking in pull requests that are otherwise fine. This causes the CI to fail and the pull request being blocked from progress until the bug in the linter is fixed, or the code is rewritten to work around the bug.
  * It is only run in the CI, or when the developer invokes the script. It would be better if the developer got the error message at compile-time, directly when writing the code.

  Fix all issues by using a `consteval` checked format string in `FatalErrorf` and `LogConnectFailure`.

  This is the first step toward https://github.com/bitcoin/bitcoin/issues/30530 and a follow-up will apply the approach to the other places.

Bitcoin Core integration/staging tree

https://bitcoincore.org

For an immediately usable, binary version of the Bitcoin Core software, see https://bitcoincore.org/en/download/.

What is Bitcoin Core?

Bitcoin Core connects to the Bitcoin peer-to-peer network to download and fully validate blocks and transactions. It also includes a wallet and graphical user interface, which can be optionally built.

Further information about Bitcoin Core is available in the doc folder.

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 (see doc/build-*.md for instructions) and tested, but it is not guaranteed to be completely stable. Tags are created regularly from release branches to indicate new official, stable release versions of Bitcoin Core.

The https://github.com/bitcoin-core/gui repository is used exclusively for the development of the GUI. Its master branch is identical in all monotree repositories. Release branches and tags do not exist, so please do not fork that repository unless it is for development reasons.

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 during the generation of the build system) with: ctest. 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. These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py

The CI (Continuous Integration) systems make 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.
