Martin Panter added the comment: David: what is the email issue you mentioned? In the mean time, I am uploading a patch to this issue.
It seems using StringIO is a bit slower than str.splitlines(). I found a way to optimize building long lines, which compensated a lot of the loss, but this optimization would apply even without using StringIO. My patch makes test.test_email 0.3% slower (the optimization alone would make it 4.4% faster), and test_email.TestFeedParsers.test_long_lines() is 3% slower (optimization 12% faster). I also tried two other alternatives to str.splitlines(), but they were both slower than the StringIO technique: * _partial is a list of UTF-8 bytes; join and use bytes.splitlines() * _partial is a UTF-8 bytearray; use bytearray.splitlines() ---------- keywords: +patch stage: needs patch -> patch review versions: +Python 3.6 Added file: http://bugs.python.org/file41177/crlf-headers.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22233> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
