New submission from Antoine Pitrou <pit...@free.fr>: See original discussion on python-dev: https://mail.python.org/pipermail/python-dev/2017-December/151328.html
Summary: binary compatibility for C extensions which don't use the stable ABI is currently "best effort" and uses distinguished flags in the tp_flags field of type objects to indicate whether a field is physically present or not. Unfortunately, tp_flags is 32 bits and therefore a scarce resource. Also, binary compatibility is 1) not guaranteed anyway 2) of less use nowadays. So we propose to remove the binary compatibility requirement when creating static type objects (i.e. not using the stable ABI). ---------- components: Interpreter Core messages: 308753 nosy: barry, paul.moore, pitrou, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: Remove cross-version binary compatibility type: behavior versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32388> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
