-Subject: [PATCH] Replace base64.*string() functions to fix py3.9 support
-
-Replace base64.decodestring() and .encodestring() functions as they
-were deprecated since Python 3.1 in favor of (equivalent) .decodebytes()
-and .encodebytes(), and were eventually removed in Python 3.9.
-
-While at it, replace most of their uses with base64.b64encode()
-and .b64decode() that are preferable to the former wrt ticket #6446,
-and they do not introduce line breaks that the twisted code usually
-discarded.
-
-Use .decodebytes() and .encodebytes() in DirDBM as it seems to rely
-on the exact presence of newlines, and changing that would break
-backwards compatibility.
-
-Fixes: ticket:6446
-Fixes: ticket:9831

-Subject: [PATCH 1/4] Replace base64.*string() functions to fix py3.9 support
-
-Replace base64.decodestring() and .encodestring() functions as they
-were deprecated since Python 3.1 in favor of (equivalent) .decodebytes()
-and .encodebytes(), and were eventually removed in Python 3.9.
-
-While at it, replace most of their uses with base64.b64encode()
-and .b64decode() that are preferable to the former wrt ticket #6446,
-and they do not introduce line breaks that the twisted code usually
-discarded.
-
-Use .decodebytes() and .encodebytes() in DirDBM as it seems to rely
-on the exact presence of newlines, and changing that would break
-backwards compatibility.
-
-Fixes: ticket:6446
-Fixes: ticket:9831

-Subject: [PATCH 2/4] Fix imap4-utf-7 codec lookup function for Python 3.9
-
-Python 3.9 normalizes the codec name into 'imap4_utf_7' rather than
-'imap4-utf-7', and therefore the lookup function needs to account
-for the former name.  Transform the latter locally to preserve support
-for all Python versions.

- py3.9
-
-In Python 3.9, the crypt.crypt() function may throw an exception
-if the underlying crypt() function fails.  Update
-verifyCryptedPassword() to account for that, and preserve the existing
-behavior of returning False in that case.
