Submit hardware profile crash

[pmb@…]

When I try to submit a hardware profile, I get a crash. I am using Fedora 17. In the user interface, I get "Encountered a problem while submitting your profile." In the frontend stdout I just get: 2012-08-10 13:03:23.204730 I Locking input devices 2012-08-10 13:03:29.673206 I Unlocking input devices

The Fedora crash report is attached, and I think it could be useful. For example:

MythDBError: Could not find database login credentials

I am using "mythfrontend version: fixes/0.25 [0.25.1-2.fc17 (c2c276d)] www.mythtv.org"

The Python bindings should be searching for your database credentials in all the same places as mythfrontend. What mysql.txt/config.xml does your frontend report it is reading on startup in its logs?

Command output after re-initialising config file

OK I may have found the problem: /home/fa2k/.mythtv/config.xml is completely empty. When I deleted it, it was re-generated, and that error went away.

The next error was: "MythTV.exceptions.MythBEError: Failed to connect to backend at blackhole.lan.fa2k.net:6543". Mythtv only listens on IPv6, but for some reason that address resolves to my IPv4 address as well, and that was used in the submission script. This is arguably a configuration issue on my part, and I set up a proxy to fix this.

With all that in place, I get the attached error.

I made a mistake, here is the correct file.

Replying to pmb@…:

The next error was: "MythTV.exceptions.MythBEError: Failed to connect to backend at blackhole.lan.fa2k.net:6543".

When not given a specific address to connect to, the Python bindings will connect to the master backend at the IP address defined for the master backend in the database. The fact that it is complaining about being unable to connect to a hostname means you have incorrectly specified a hostname in mythtv-setup where it asks for an IP.

The error listed in the attached log merely shows the hardware profiler is not robust against an invalid display profile. I'm not sure how you would have gotten a display profile with no preferred decoder.

[pmb@…]

Good that it's understood. I have messed with the profiles a lot, but I don't have an empty profile in the UI.

In b5e154fe816742b18adcc73e409044f06a4b723e/mythtv:

Make hardware profiler ignore errors and continue.

This wraps the various subsets of MythTV data extracted from the
database with a 'try' block, allowing it to ignore and proceed if one of
the subsets fails due to bad data or an unexpected configuration.
