New submission from tzing <tzings...@gmail.com>:
Python's builtin `email.parser.BytesParser` could not properly parse the message when the bytes starts with BOM. Not 100% ensured- but this issue seems cause by that `FeedParser._parsegen` could not match any of the header line after the data is decoded. Steps to reproduce: 1. get email sample. any from https://github.com/python/cpython/tree/master/Lib/test/test_email/data. I use msg_01.txt in following code 2. re-encoded the mail sample to some encoding with BOM 3. use `email.parser.BytesParser` to parse it ```py import email with open('msg_01.txt', 'rb') as fp: msg = email.parser.BytesParser().parse(fp) print(msg.get('Message-ID')) ``` Expect output `<15090.61304.110929.45...@aaa.zzz.org>`, got `None` ---------- components: Library (Lib) messages: 388929 nosy: tzing priority: normal severity: normal status: open title: email.parser.BytesParser failed to parse mail when it is with BOM type: behavior versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43530> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
