sig does not use iso8601: no need to silence its logging Signed-off-by: Jussi Kukkonen <[email protected]>
Our 'expires' strings are constrained by the ISO8601_DATETIME_SCHEMA
which matches regex '\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}Z'. This can be
parsed with just a datetime.strptime(): iso8601 module is not needed.
* Add formats.expiry_string_to_datetime() helper function
* Modify the 3 locations that used iso8601 and the api/metadata.py usage
of datetime.strptime()
* Remove related unnecessary logger setup
* Add the missing exception documentation to relevant functions (in many
cases the exception is rather unlikely as the schema has been verified
many times before this though...)
Fixes theupdateframework#1065

There was a problem hiding this comment.
note that I'm not doing the replace() in my version: I could not think of a case where it would be useful.

Makes perfect sense. I guess I thought that strptime might adopt the system timezone. Thanks for removing unnecessary code!

Fixes #1065
The reason for doing this is again vendoring into pip: I'd like to not have to vendor iso8601 as well.
