Hi, I would like to ask your guidance as I'm entirely sure whether the
I've tried using newly released Python 3.11 interpreter in some of my
26.10.22 11:17, Piotr Waszkiewicz пише: problem I'm experiencing should be posted in CPython's repo as a bug issue. projects and one of them failed to start with "RuntimeError: invalid SRE code" error.
Looking into implementation of one of the dependencies I've found out
that the issue has been found out by a maintainer and fixed ( https://github.com/pydicom/pydicom/issues/1658).
It looks like this particular regexp caused the `re.compile()` method to raise:
``` re.compile( r"(?P<h>^([01][0-9]|2[0-3]))" r"((?P<m>([0-5][0-9]))?" r"(?(5)(?P<s>([0-5][0-9]|60))?)" r"(?(7)(\.(?P<ms>([0-9]{1,6})?))?))$" ) ```
I've checked and this hasn't been an issue in all previous Python interpreter versions, starting from 3.6 (the oldest I've checked). What's more the regex i correctly recognized and does not cause any issues in other regexp implementations, e.g. the online tool https://regex101.com/
Could somebody help me decide whether this is indeed a bug?
Yes, it is a bug, and I have found its cause. Please open an issue on the CPython bug tracker.
