[mythtv-users] TheTVdb lookups failing since v29 upgrade

[Mike Holden]

Hi All,

system is Fedora on versions 25 and 26, the same issue is happening on
various frontends. BE is on Fedora 25.

Since the upgrade to 29, lookups from thetvdb are failing.

Here's an extract from the frontend log at the lookup time:
2017-12-09 16:35:22.676245 I  Running Grabber:
/usr/share/mythtv/metadata/Television/ttvdb.py -l en -a GB -D 221630 4 10

10
2017-12-09 16:35:25.194461 I  No results found for Scorpion 4 10

Running the lookup query from the commandline:

[mike at hagrid ~]$ /usr/share/mythtv/metadata/Television/ttvdb.py -l en -a GB
-C 221630
Traceback (most recent call last):
  File "/usr/share/mythtv/metadata/Television/ttvdb.py", line 2464, in
<module>
    sys.exit(main())
  File "/usr/share/mythtv/metadata/Television/ttvdb.py", line 2169, in main
    userkey=tvdb_account.account_identifier)
  File "/usr/lib/python2.7/site-packages/MythTV/ttvdb/tvdb_api.py", line
693, in __init__
    self.session.remove_expired_responses()
  File
"/usr/lib/python2.7/site-packages/MythTV/ttvdb/requests_cache_compatability.py",
line 40, in remove_expired_responses
    self.cache.remove_old_entries(datetime.utcnow() -
self._cache_expire_after)
TypeError: unsupported operand type(s) for -: 'datetime.datetime' and 'int'

The relevant section of code at that location is:

    def remove_expired_responses(self):
        """ Removes expired responses from storage
        """
        if not self._cache_expire_after:
            return
        self.cache.remove_old_entries(datetime.utcnow() -
self._cache_expire_after)

The issue seems to be the subtraction of time (seconds?) from "now", giving
a type mismatch.

Grabber version is:
[mike at hagrid ~]$ /usr/share/mythtv/metadata/Television/ttvdb.py --version
<grabber>
  <name>TheTVDB.com</name>
  <author>R.D.Vaughan</author>
  <thumbnail>ttvdb.png</thumbnail>
  <command>ttvdb.py</command>
  <type>television</type>
  <description>Search and metadata downloads for thetvdb.com</description>
  <version>2.0.0</version>
</grabber>

Anyone else having this issue? Not seen it mentioned on here before.

Best regards
