* Remove script_plugins * Use crown instead of script_plugins * crown_is_not_used * Use crown in command base * bootstrap crown * tidy happy * disable sccache * Bring crown in tree * Install crown from tree * fix windows ci * fix warning * fix mac libscript_plugins.dylib is not available anymore * Update components/script/lib.rs Co-authored-by: Martin Robinson <mrobinson@igalia.com> * Update for nightly-2023-03-18 Mostly just based off https://github.com/servo/servo/pull/30630 * Always install crown it's slow only when there is new version * Run crown test with `mach test-unit` * Small fixups; better trace_in_no_trace tests * Better doc * crown in config.toml * Fix tidy for real * no sccache on rustc_wrapper * document rustc overrides * fixup of compiletest * Make a few minor comment adjustments * Fix a typo in python/servo/platform/base.py Co-authored-by: Samson <16504129+sagudev@users.noreply.github.com> * Proper test types * Ignore tidy on crown/tests --------- Co-authored-by: Martin Robinson <mrobinson@igalia.com>
