New submission from Paul Ganssle <p.gans...@gmail.com>:
When reviewing PR 12020 fixing an infinite loop in the e-mail module, I noticed that a *different* infinite loop is documented with a "# XXX" comment on line 2724: https://github.com/python/cpython/blob/58721a903074d28151d008d8990c98fc31d1e798/Lib/email/_header_value_parser.py#L2724 This is triggered when the policy's `max_line_length` is set to be shorter than minimum line length required by the "RFC 2047 chrome". It can be reproduced with: from email.policy import default policy = default.clone(max_line_length=7) # max_line_length = 78 policy.fold("Subject", "12345678") I could not find an entry on the tracker for this bug, but it is documented in the source code itself, so maybe I just didn't try hard enough. Related but distinct bugs: #33529, #33524 I will submit a patch to fix this. ---------- messages: 339660 nosy: barry, p-ganssle, r.david.murray priority: normal severity: normal status: open title: Infinite loop with short maximum line lengths in EmailPolicy versions: Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36564> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
