Dev Call: 6 October 2022

Present

• Discussion item: Mixed mode binary verification step? https://github.com/hpyproject/hpy/issues/366

• Discussion item: Limited contexts for tp_traverse and tp_destroy

  Mark has proposed limited contexts for these slots: https://github.com/markshannon/New-C-API-for-Python/blob/main/DesignRules.md#all-functions-to-take-an-opaque-context

  It would help with the numpy port if we could have e.g. ctx->Mem_Free available to tp_destroy; or ctx->Field_Load, ctx->Global_Load, ctx->Type and ctx->Is available to tp_traverse

• Discussion item: Clarify encoding used for C strings in the API. #355

  How much should we start to deviate from CPython towards the "ideal" API already now?

• Discussion item: 1.0 release? Should we aim for one since we'll have the ABI version check very soon?
