New submission from Manfred Kaiser <manfred.kai...@logfile.at>:
I used email.parser.BytesParser for parsing mails. In one programm I used parse, because the email was stored in a file. In a second programm the email was stored in memory as a bytes object. I created hash values from each parts an compared them, to check if a part is already known to my programs. This works for attachments, but not for html and plain text parts. Documentation for parsebytes: Similar to the parse() method, except it takes a bytes-like object instead of a file-like object. Calling this method on a bytes-like object is equivalent to wrapping bytes in a BytesIO instance first and calling parse(). When I read the documentation, I expected that both methods will produce the same output. The testmail contains 2 mimeparts. One with html and one with plain text. The parse method with a file and the parse method with bytes-data, wrapped in a BytesIO produces the same hashes. The paesebytes method creates different hashes. Output of my testprogram: MD5 sums with parsebytes with bytes data 3f4ee7303378b62f723a8d958797507a 45c72465b931d32c7e700d2dd96f8383 ------------------------ MD5 sums with parse and BytesIO with bytes data fb0599d92750b72c25923139670e5127 9a54b64425b9003a9e6bf199ab6ba603 ------------------------ MD5 sums with parse from file fb0599d92750b72c25923139670e5127 9a54b64425b9003a9e6bf199ab6ba603 Is this an expected behavior or is this an error? ---------- components: email files: test.eml messages: 358533 nosy: barry, mkaiser, r.david.murray priority: normal severity: normal status: open title: email.parser.BytesParser - parse and parsebytes work not equivalent versions: Python 3.5, Python 3.6, Python 3.7, Python 3.8 Added file: https://bugs.python.org/file48785/test.eml _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39071> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
