Filter causes exception

[HenryHu]

If all the messages obtained in one update are filtered out, an exception occurs:

Traceback (most recent call last):
File "/usr/local/lib/python2.7/site-packages/turpial-3.5.9.dev0-py2.7.egg/turpial/ui/qt/main.py", line 772, in after_update_column
self.container.update_column(column.id, updates)

if statuses[0].repeated_by:
IndexError: list index out of range

The reason is clear. But to fix it, there are problems I'm not sure about:

• Shall we play update sound in this case?
• Shall we show notification in this case?

Hey @HenryHu,

Yes, we should play the update sound and we should show a notification. For this specific case, notifications module has support to show how many tweets have been filtered. If you check notification.py#L49-L67, you'll see that calling something like:

notify.updates('my-column', 0, 10)

Should show a message like: No new tweets (10 tweets have been filtered). That way we let the user know that there is an active filter that is doing its job.

Any other doubt or concern, do not hesitate to contact me.

Cheers!
