SCons: Format buildsystem files with psf/black Configured for a max line length of 120 characters. psf/black is very opinionated and purposely doesn't leave much room for configuration. The output is mostly OK so that should be fine for us, but some things worth noting: - Manually wrapped strings will be reflowed, so by using a line length of 120 for the sake of preserving readability for our long command calls, it also means that some manually wrapped strings are back on the same line and should be manually merged again. - Code generators using string concatenation extensively look awful, since black puts each operand on a single line. We need to refactor these generators to use more pythonic string formatting, for which many options are available (`%`, `format` or f-strings). - CI checks and a pre-commit hook will be added to ensure that future buildsystem changes are well-formatted. 2020-03-30 08:28:32 +02:00			`Import("env")`

Running builder (content generator) functions in subprocesses on Windows - Refactored all builder (make_) functions into separate Python modules along to the build tree - Introduced utility function to wrap all invocations on Windows, but does not change it elsewhere - Introduced stub to use the builders module as a stand alone script and invoke a selected function There is a problem with file handles related to writing generated content (.gen.h and *.gen.cpp) on Windows, which randomly causes a SHARING VIOLATION error to the compiler resulting in flaky builds. Running all such content generators in a new subprocess instead of directly inside the build script works around the issue. Yes, I tried the multiprocessing module. It did not work due to conflict with SCons on cPickle. Suggested workaround did not fully work either. Using the run_in_subprocess wrapper on osx and x11 platforms as well for consistency. In case of running a cross-compilation on Windows they would still be used, but likely it will not happen in practice. What counts is that the build itself is running on which platform, not the target platform. Some generated files are written directly in an SConstruct or SCsub file, before the parallel build starts. They don't need to be written in a subprocess, apparently, so I left them as is. 2018-03-17 23:23:55 +01:00			`from platform_methods import run_in_subprocess`

Dynamically load libudev.so.1 on Linux if `udev=yes` This makes it possibly to run Linux binaries compiled with udev support on Linux systems which do not provide udev (typically systemd-less distros). If udev is missing, we fall back to parsing `/dev/input` like when compiled without udev support (`udev=no`). Also adding some verbose debug statements to know which method we're using when debugging Linux joypad issues. The libudev so wrappers were generated on Mageia 8 with libudev 246.9 using https://github.com/hpvb/dynload-wrapper: ``` ./generate-wrapper.py --include /usr/include/libudev.h --sys-include '<libudev.h>' \ --soname libudev.so.1 --init-name libudev --omit-prefix gnu_ \ --output-header libudev-so_wrap.h --output-implementation libudev-so_wrap.c ``` 2021-02-17 11:28:27 +01:00			`if "udev" in env and env["udev"]:`
