Respond to the low-hanging code review fruit:
- Clean up some comments
- Remove an acidentally added duplicate init_autosave
- Combine two test_history tests
- Move test_init cleanup into a fixture to ensure it gets called.
- Name the _ argument of bind(_) to _key
- Ensure index is valid for first_item/last_item
- Move SqlException to top of module
- Rename test_index to test_getitem
- Return QItemFlags.None instead of None
- Fix copyright dates (its 2017 now!)
- Use * to force some args to be keyword-only
- Make some returns explicit
- Add sql to LOGGER_NAMES
- Add a comment to explain the sql escape statement
newest_slice is no longer needed after the completion refactor. Now that
history is based on the SQL backend, LIMIT is used instead.
StatusBar._option is not used, though I'm not sure why vulture only caught it
now.
test_history.test_init also leaked state by leaving the instantiated history as
the parent of the QApp, which was causing test_debug to fail because it was
trying to dump the history object left from test_history.
test_selectors and test_get_all_objects were running fine on my machine, but
for some reason is failing with "Driver not loaded" on Travis. Let's try
initializing SQL and see what happens.
Instead of returning a regular tuple and trying to remember which index maps to
which field, return named tuples that allow accessing the fields by name.
Allow categories to specify a WHERE clause that applies in addition to the
pattern filter. This allows the url completion model to filter out redirect
entries.
This also fixed the usage of ESCAPE so it applies to all the LIKE statements.
A SQL completion category can now provide a customized column expression for
the select statement. This enables the url model to format timestamps, as well
as rearrange the name and url in the quickmark section.
This allows setting the query as a QSqlQuery instead of a string, which allows:
- Escaping quotes
- Using LIMIT (needed for history-max-items)
- Using ORDER BY (needed for sorting history)
- SELECTing columns (needed for quickmark completion)
- Creating a custom select (needed for history timestamp formatting)
- Adjust _check_completions to work for CompletionModel and SqlCompletionModel
- Move sql initialization into a reusable fixture
- Remove the bookmark/quickmark/history stubs, as they're now handled by sql
- Disable quickmark/bookmark model tests until their completion is ported to
sql.
- Disable urlmodel tests for features that have to be implemented in SQL:
- LIMIT (for history-max-items)
- Configurable column order (for quickmarks)
- Configurable formatting (for timestamp-format
For URL completion, time-based sorting is handled by the SQL model.
All the other models use simple alphabetical sorting. This allowed cleaning up
some logic in the sortfilter, removing DUMB_SORT, and removing the
completion.Role.sort.
This also removes the userdata completion field as it was only used in url
completion and is no longer necessary with the SQL model.
The browser-wide in-memory web history is now stored in an in-memory sql
database instead of a python dict. Long-term storage is not affected, it
is still persisted in a text file of the same format.
This will set the stage for SQL-based history completion.
See #1765.
When qutebrowser starts, it creates an in-memory sqlite database. One
can instantiate a SqlTable to create a new table in the database. The
object provides an interface to query and modify the table.
This intended to serve as the base class for the quickmark, bookmark,
and history manager objects in objreg. Instead of reading their data
into an in-memory dict, they will read into an in-memory sql table.
Eventually the completion models for history, bookmarks, and quickmarks
can be replaced with SqlQuery models for faster creation and filtering.
See #1765.
The new completion API no longer needs either of these. Instead of
referencing an enum member, cmdutils.argument.completion now points to
a function that returnsthe desired completion model.
This vastly simplifies the addition of new completion types. Previously
it was necessary to define the new model as well as editing usertypes
and completion.models.instances. Now it is only necessary to define a
single function under completion.models.
This is the next step of Completion Model/View Revamping (#74).
First step of Completion Model/View revamping (#74). Rewrite the
completion models as functions that each return an instance of a
CompletionModel class.
Caching is removed from all models except the UrlModel. Models other
than the UrlModel can be generated very quickly so caching just adds
needless complexity and can lead to incorrect results if one forgets to
wire up a signal.
The test fails on Ubuntu Xenial because QtOpenGL is not installed.
This isn't a problem with real-life usage though, as we only call it with
QtWebEngine, and that ensures that QtOpenGL is available.
Apart from checking for buttons with an href attribute (which made no sense at
all and should never return any element) this was identical to
webelem.Group.links.
There's actually no good reason to filter javascript links as we might want to
click them (or copy their URL) just like any other link - this fixes#2404.
With that being gone, we don't need FILTERS at all anymore, as we can check for
existence of the href attribute in the CSS selector instead.
With coverage 4.4, the source name (qutebrowser/) is not added to the filename
anymore. To adjust for that, we remove qutebrowser/ from all paths, and also
make sure to remove it from what coverage returns (in case someone is running an
older version).
This allows users to change the size of the favicon independently from
the size of the font/tab, in order to adjust the balance between
favicons and text. The drawing code is also adjusted to place the icon
relative to the text center, rather than the text top.
Works as expected even for values of 0.0 (which is equivalent to hiding
the favicon completely).
Closes#2549.
This benchmark was running very quickly due to an improper setup.
The current history implementation expects that a newly inserted entry must
be more recent than any existing entries and sorts according to this
assumption.
The benchmark test inserts increasingly older entries, breaking this invariant.
When run in the benchmark, the qute://history/data implementation would
see an entry older than the oldest time in the time window and would
immediately return with a single "next" entry.
This patch inserts data in an order that mantains history's invariant and adds
a sanity-check at the end of the test. It does not check for the exact length
as not all entries will be within the time window. The length will be some
values <= 100000, the check just ensures that there is at least something more
than a "next" entry.

From the spec:
User agents should ensure, e.g. by means of an overlay, that the end user is
aware something is displayed fullscreen. User agents should provide a means of
exiting fullscreen that always works and advertise this to the user. This is
to prevent a site from spoofing the end user by recreating the user agent or
even operating system environment when fullscreen.
