OverflowErrors and 500 on home page when setting max expiry offset to extremely large numbers

[helpimnotdrowning]

As a new user, I'm looking for a fileshare that doesn't auto-expire my uploaded files (single-user). In exploring the app settings before I use it, I set "Maximum Expiry Offset (hours)" to "99999999999999999999999999999999999999".

This results a home page with only the text "Server Error (500)"

, and the following error printed to the docker log:

OverflowError: Python int too large to convert to C int

Using a value of 2147483646 (less than the 32bit signed int limit) gives a different OverflowError:

OverflowError: date value out of range

Hi! Thanks for the bug report.

Just released v0.4.1 - could you give that a try? I've fixed up the validation so you should get better errors at the least, and setting 2147483646 as the max expiry offset will give you enough headroom I hope!

I've also created #428 to follow up on making the expiry date fully optional. Thanks for the suggestion!
