New submission from STINNER Victor: Attached patch makes _sre.compile() more strict on types: groupindex must be a dictionary and indexgroup must be a tuple.
Currently, indexgroup is passed as a list. I chose to convert it to a tuple to use less memory and to prevent unwanted changes. For unwanted changed, I'm not sure because groupindex remains a mutable dictionary. Do you think that it's worth it to require a tuple? Another option is to accept a list but to convert it to a list, but this change is more specific to the current implementation. ---------- files: sre_types.patch keywords: patch messages: 281373 nosy: haypo, serhiy.storchaka priority: normal severity: normal status: open title: _sre.compile(): be more strict on types of indexgroup and groupindex type: enhancement versions: Python 3.7 Added file: http://bugs.python.org/file45590/sre_types.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28765> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
