No Internet Connection - No Entertainer

[Andrew]

I don't know whether this is just me, but if you disconnect your pc from the internet (right click on the nm-applet in ubuntu and untick Enable Networking) then the Entertainer Backend says it starts, however it must crash as it does not then show up in task list.

[Joshua Scotton (joshuascotton)]

I can't test this atm, although I think you're probably right.

You can run the entertainer-backend in the frontend by the following command:
./entertainer-backend.py --foreground

this should give you some more info on the problem

[Andrew (and471)]

Okay, here is the output I get when I run the command mentioned above. (It seems to be to do with Album Art)

First of all, I'm not surprised that this bug exists. Today, my internet has sucked, and I'm experiencing this problem firsthand. I would like to see EVERYWHERE there is a request to go out to the internet wrapped in a try/except block with proper error handling.

To find where the issues are, turn off your network and run the tests. There are a few places that need to be looked at.

Once these fixes are ready, I'd like to merge this into the 0.1 branch for a 0.1.1 point release

[Samuel Buffet (samuel-buffet)]

This is not a bug anymore since Paul fixed the backend to not automatically rebuild the cache.

I've made tests without internet connection. Trunk and latest released package are running fine.

Of course it may be a problem to rebuild cache offline but this is really another issue.

So I close that bug.

[Samuel Buffet (samuel-buffet)]

I was wrong...

The weather screen is broken without Internet connection.

Bug reopened.

[Samuel Buffet (samuel-buffet)]

The lyrics download is also crashing.

But not the feeds update.

[Samuel Buffet (samuel-buffet)]

I've found nothing failing with a dead Internet connection.

So I set this bug status to "Fix committed" but I'll reopen it if I find something wrong later.
