Supercedes #90117, albeit through the exact opposite approach: ensuring all generated files are removed during cleanup. This was achieved by extending the
write_file_if_needed
function that already attached itself to all generic generation methods (ie: not tied to SCons) with a dedicated SCons environment. The only purpose of this environment is to declare the files as cleanable & to skip any file comparison/creation logic during cleanup.Below compares behavior for an SCons clean followed by git clean. The difference between the two is exclusively the generated files not being present in the PR, having already been successfully cleaned out by SCons.
