Buffering the output of clang-tidy will kill colored output, because the tools being run are not going to see isatty() return true anymore. To avoid that, pass b_colorout down to the clangtidy script. As a bonus, this fixes -Db_colorout=never which was producing colored output from clang-tidy.

Differentiate from the "run_tool_on_targets" function that will be introduced in the next commit. Signed-off-by: Paolo Bonzini <[email protected]>
It is useful to apply a limit to the number of processes even outside "meson test", and specifically for clang tools. In preparation for this, generalize determine_worker_count() to accept a variable MESON_NUM_PROCESSES instead of MESON_TESTTHREADS, and use it throughout instead of multiprocessing.cpu_count().

This improves the handling of keyboard interrupt, and also makes it easy to buffer the output and not mix errors from different subprocesses. This is useful for clang-tidy and will be used by clippy as well. In addition, the new code supports MESON_NUM_PROCESSES. Signed-off-by: Paolo Bonzini <[email protected]>
There is no need to create and look up a dictionary when MachineChoice is an enum, and there is no need to create a PerMachine object on every __setitem__ of another PerMachine object. Signed-off-by: Paolo Bonzini <[email protected]>
Even though the "targets" introspection info already includes the command line arguments used to invoke the compiler, this is not enough to correlated with the "compilers" introspection info and get extra information from there. Together with the existing "language" key, adding a "machine" key is enough to identify completely an entry in the compilers info. Signed-off-by: Paolo Bonzini <[email protected]>
Similar to the "ninja scan-build" target for C, add a clippy internal tool that runs clippy-driver on all crates in the project. The approach used is more efficient than with "ninja scan-build", and does not require rerunning Meson in a separate build directory; it uses the introspection data to find the compiler arguments for the target and invokes clippy-driver with a slightly modified command line. This could actually be applied to scan-build as well, reusing the run_tool_on_targets() function. Signed-off-by: Paolo Bonzini <[email protected]>
Add a target that builds all crates that could be extern to others, and then reruns clippy. Signed-off-by: Paolo Bonzini <[email protected]>
clippy-driver is not meant to be a general-purpose compiler front-end. Since Meson can now provide natively the ability to invoke clippy, raise a warning if someone uses it that way. Signed-off-by: Paolo Bonzini <[email protected]>
It is needed by objfw. Signed-off-by: Paolo Bonzini <[email protected]>

This is very similar to clippy, with different command line of course. Also it can change files, so do not run it twice on the same file. Signed-off-by: Paolo Bonzini <[email protected]>
