  "message": "[gn] use action() instead of copy() for libcxx headers (#195948)\n\ncopy() doesn\u0027t handle file deletions. Use an action() that syncs the\noutput directory with the input list via a response file, removing files\nthat are no longer in the list.\n\nThis works because if files are added or removed, ninja\u0027s command line\ntracking re-runs the script, and if contents of existing files change,\nninja\u0027s input mtime checking reruns it.\n\nThis also makes the remove_float_h workaround unnecessary.\n\nMotivated by all the recent header removals in libc++.",
