New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>:
The EAFP principle is widely used in the regular expressions parsing code. Exceptions like KeyError, IndexError, ValueError or OverflowError raised during parsing are converted into a helpful re.error. Expression chaining is usually suppressed in such cases to hide unrelated implementation details, but not in all cases. The following PR adds more "from None" in "raise" statements inside "except" blocks. ---------- components: Library (Lib), Regular Expressions messages: 416774 nosy: ezio.melotti, mrabarnett, serhiy.storchaka priority: normal severity: normal status: open title: Suppress expression chaining for RE parsing errors type: enhancement versions: Python 3.11 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue47227> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
