The upcoming Python 3.13 will remove the built-in module
imghdr.Its mimetype-sniffing functionality was copied into
email.mime, so I switched to it inflanker/mime/message/part.py.The same file also uses
email.mime.audio._whatsnd, but since it's an internal underscore-prefixed function, it's not part of the stable API and was renamed in Python 3.11.Instead of using
email.mime.audio._whatsnd/_whatandimghdr/email.mime.image._what, I think it's safer to use the stable wrapper classesMIMEAudio,MIMEImage, even though they require a bit more work to extract the sniffed content type.If you disagree, I can switch back to using the internal function.
I tested this with Python 3.10 - please test with 2.7.
BTW, another deprecated module is
cgi, whichwebobuses, but there's an open issue about it upstream, and I'm waiting to see if they intend to release a new version.
