gh-155218: Generate the option group flags in a stable order - #155219
Merged
Conversation
They were emitted in the iteration order of a set of group identifiers. The identifiers of the groups before the required parameters are small negative integers, -1 and -2 have the same hash, so their order depended on the size of Py_hash_t, and the code generated on a 32-bit platform differed from the checked in one. They are now emitted in the order of the parameters. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The flags of the optional groups were emitted in the iteration order of a set of group identifiers.
The identifiers of the groups before the required parameters are small negative integers, and
hash(-1) == hash(-2) == -2, so the order of these colliding keys depends on the size ofPy_hash_t.A 32-bit build therefore generated
Modules/clinic/_cursesmodule.c.h(addch(),addstr()and 7 other functions) differently from the checked in file.The flags are now emitted in the order of the parameters.
