build: implement clang-tidy using our plugin The principle of this is that you can either externally build it with Nix (actual implementation will be in a future commit), or it can be built with meson if the Nix one is not passed in. The idea I have is that dev shells don't receive the one from Nix to avoid having to build it, but CI can use the one from Nix and save some gratuitous rebuilds. The design of this is that you can run `ninja -C build clang-tidy` and it will simply correctly clang-tidy the codebase in spite of PCH bullshit caused by the cc-wrapper. This is a truly horrendous number of hacks in a ball, caused by bugs in several pieces of software, and I am not even getting started. I don't consider this to fix the clang-tidy issue filing, since we still have a fair number of issues to fix even on the existing minimal configuration, and I have not yet implemented it in CI. Realistically we will need to do something like https://github.com/Ericsson/codechecker to be able to silence warnings without physically touching the code, or at least diff reports between versions. Also, the run-clang-tidy output design is rather atrocious and must not be inflicted upon anyone I have respect for, since it buries the diagnostics in a pile of invocation logs. We would do really well to integrate with the Gerrit SARIF stuff so we can dump the reports on people in a user-friendly manner.

clang-tidy: write a lint for charptr_cast This lets us ensure that nobody is putting in new reinterpret_cast instances where they could safely use charptr_cast instead. Change-Id: I6358a3934c8133c7150042635843bdbb6b9218d4 2024-08-05 07:02:53 +02:00			`'CharPtrCast.cc',`
