Adds a new file for tests relating to WebEngineTab, it looks a little
sparse right now but I'm sure there will be more soon.
Tests that scripts with invalid world IDs are rejected appropriately and
the ones with valid world IDs aren't rejected.
The `FakeWidget` thing is so `sip.isdeleted` didn't complain about being
passed the wrong type.
Previously calling `script.code()` would fail if the script didn't have
a `name`. This wasn't being hit in practice because the only place that
constructs GreasemonkeyScripts was checking for that condition and add
the filename there as a fallback.
This change make the `name` attribute more explicitly mandatory by
failing with a `ValueError` if it is not provided and make it still
possible to use the filename fallback in that case by adding a
`filename` keyward argument to `__init__()`.
Additionally where `script_meta` is used in `script.code()` a fallback
to and emptry string was added so it doesn't fail for raw javascript
files without greasemonkey metadata.
If the blacklist is only valid for the completion, the setting should also be
under completion.
This also un-renames history.gap_interval and renames
completion.web_history_max_items.
This adds a new CompletionMetaInfo table which is a simple key/value store.
Thanks to Python/sqlite duck typing, we can use that to store values of any
type, even new ones in the future.
Currently, the only allowed key is force_rebuild, which forces a rebuild of the
CompletionHistory table. This will be needed for a future change.
For some reason I don't comprehend right now, disabling it breaks
test_focusing_download_widget_via_tab. I'm having exams tomorrow and the day
after that, so meh, let's just re-enable that test for now as a stopgap
solution.
`ListCategory` sorts its completion by default, we are already building
the categories in the right order so don't need that.
The test tests the case of where you have 11 tabs and if the model was
sorted the tabs with index 10 and 11 would be sorted before the one with
index 2.
The `random.sample` bit for the tab url and title is to also make sure
the model isn't being sorted on those columns, whithout haveng to write
and all ten lines.
