2024-08-04build: implement clang-tidy using our pluginJade Lovelace
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.

2024-06-06build: expose option to enable or disable precompiled std headersQyriad
They are enabled by default, and Meson will also prints whether or not they're enabled at the bottom at the end of configuration. Change-Id: I48db238510bf9e74340b86f243f4bbe360794281

2024-04-17Merge "build internal API docs with Meson" into mainQyriad
2024-04-15build internal API docs with MesonQyriad
This commit adds the capability for building the Doxygen internal API docs in the Meson buildsystem, and also makes doing so the default for the internal-api-docs hydra job. Aside from the /nix-support directory, which differed only by the hash part of a store path, the outputs of hydraJobs.internal-api-docs before and after this commit were bit-for-bit identical on my machine.

2024-04-11meson: fix log-direldritch horrors
the make build system sets this with an extra /nix segment. Change-Id: Iedf464843196faeae5b59698837faca3a4f23586
2024-04-09meson: correctly differentiate $profiledir and $sysconfdir/profile.dQyriad
The configured sysconfdir is used to look for nix.conf, so it needs to be /etc, and not $out/etc, so we separate out the place where shell profile files are installed, which is the only other place sysconfdir is at all used. See https://git.lix.systems/lix-project/lix/issues/231#issuecomment-1989 for more info. Change-Id: Idbed8ba82e711b8a9d6b6127904befa27d58e279
2024-04-01meson: add switch to disable docseldritch horrors
the make build system can do this too. Change-Id: I8c07d159cab54a8749c50dc33615f60bd251a86d
2024-03-29meson: fix state-dir default valueeldritch horrors
the autoconf build system defaults to /nix/var, not /nix/var/nix. the latter is only used in libstore, so we'll move the extra segment there. Change-Id: Idfbc988ee302355982abdcd51d6d7b5d5d661c0d
2024-03-27Enable clang build timing analysisJade Lovelace
I didn't enable this by default for clang due to making the build time 10% worse or so. Unfortunate, but tbh devs for whom 10% of build time is not *that* bad should probably simply enable this. Change-Id: I8d1e5b6f3f76c649a4e2f115f534f7f97cee46e6
2024-03-26meson: implement unit testsQyriad
Unit tests can be run with `meson test -C build --suite check`. `--suite check` is optional, as right now that's the only test suite, but when functional tests are added those will be in a separate suite. Change-Id: I7f22f1cde4b489b3cdb5f9a36a544f0c409fcc1f
2024-03-22build: optionally build and install with mesonQyriad
This commit adds several meson.build, which successfully build and install Lix executables, libraries, and headers. Meson does not yet build docs, Perl bindings, or run tests, which will be added in following commits. As such, this commit does not remove the existing build system, or make it the default, and also as such, this commit has several FIXMEs and TODOs as notes for what should be done before the existing autoconf + make buildsystem can be removed and Meson made the default. This commit does not modify any source files. A Meson-enabled build is also added as a Hydra job, and to `nix flake check`. Change-Id: I667c8685b13b7bab91e281053f807a11616ae3d4
