That worked while every option used action='store' or 'store_const' (both accept const), but 313522@main added --cmake with action='store_true'. argparse's _StoreTrueAction.__init__ does not accept a const keyword, so the loop now raises: TypeError: __init__() got an unexpected keyword argument 'const' before the parser is even built, breaking both scripts at startup. Only forward const= for the actions that accept it (store_const, append_const). All other options keep their previous behavior. 2212217 1 webkit-bug-importer 2026-05-19 15:48:57 -0700 <rdar://problem/177472652> 2212219 2 zakr 2026-05-19 15:54:49 -0700 Pull request: https://github.com/WebKit/WebKit/pull/65228 2212228 3 ews-feeder 2026-05-19 16:01:32 -0700 Committed 313527@main (85a8efec82da): <https://commits.webkit.org/313527@main> Reviewed commits have been landed.
