Having thread pool as its own singleton in the library meant that each
kiface had its own threadpool, leading to many multiples of the threads
being started. Placing a singleton class in PGM_BASE ensures that all
kifaces use the same thread pool.
The singleton class can be extended to provide single instance
guarantee for any element across kifaces
It fixes a link issue on W10/msys2 when building some .exe files
not related to QA tests, but have the unit_test_framework library linked
without this change..
Our minimum C++ version is C++17, which has std::filesystem, so ditch
the boost dependency and use the standard library instead. (this only
affects temp file creation in the QA suite anyway).
One test has pads of a bunch of different shapes and provokes some
errors to make sure they're caught.
The others are all past issues with the zone filler to make sure we
don't suffer any regressions. (They should all just pass with no DRC
errors.)
Move into own include directory for clarity. Also allows qa_utils
to use its own private headers in qa/qa_utils without exposing them
through the target_include_directories directive.
Add a tool that allows a user to run DRC functions
on a given KiCad PCB file.
The first available functions are the courtyard functions.
Also move most of the utility program logic into qa_util for
better reusability.
If qa_utils is not explicitly declared with STATIC, the build
fails in environments where the BUILD_SHARED_LIBS CMake option is
present and set to "ON". An example of this is Fedora COPR.
This adds a test program which can be used to test the
parsing of a given KiCad PCB file. This interface is
useful for both manual or automated debugging of given
files, as well as providing an interface suitable for
fuzz-testing tools.
Also adds to the testing docs to detail how fuzzing can
be used.
Also moves some useful re-usable code from io-benchmark
to a new library qa_utils, which can contain code that
isn't need in the actual KiCad libs.
