Now the "object" kind of value (like in YAML) is stored internally, and that's
the canonical value. The methods changed their meaning slightly, see the
docstring in configtypes.py for details.
- Fix outdated comments
- Use mock specs when possible
- More precise error message check in test_import_txt_invalid.
- Fix copyright message
- Tweak missing pyqt error message
- Dead code: remove group_by and where from sqlcategory.
With the new separate completion table, these are no longer used.
- Move test_history out of webkit/. History is no longer purely webkit
related, it could be webengine.
This ensures we actually know when an AttributeError happens.
It also changes most external code to use the correct environment, rather than
simply creating a jinja2.Template, which wouldn't use the more tightened
environment.
When binding a key, the first row will be the current binding if the key
is already bound. This should make it easier for users to tell when they
are binding a key that is already bound, and what it is bound to.
Taking the completion widget as an argument was overly complex.
The process now looks like:
1. CompletionView gets deletion request
2. CompletionView passes selected index to CompletionModel
3. CompletionModel passes the row data to the owning category
4. The category runs its custom completion function.
This also fixes a bug. With the switch to the hybrid (list/sql)
completion model, the view was no longer updating when items were
deleted. This fixes that by ensuring the correct signals are emitted.
The SQL model must be refreshed by running the query. We could try using
a SqlTableModel so we can call removeRows instead.
The test for deleting a url fails because qmodeltester claims the length
of the query model is still 3.
This allows replace to be a named parameter and allows consolidating
some duplicate code between various insert methods.
This also fixes some tests that broke because batch insert was broken.
No longer needed with sql backend. Query results build their own
namedtuple from the returned columns, and inserting new entries is just
done with named parameters.
This is called often, hopefully a prepared query will speed it up.
This also modifies Query.run to return self for easier chaining, so you
can use `query.run.value()` instead of `query.run` ; query.value()`.
For real this time. A mistake on the last commit like this meant models
were still spuriously instantiated.
Now that the completion model is reused, the layoutChanged signal needs
to be forwarded through, otherwise the view will not update.
This seemed to have a significant performance impact. Removing it means
that instead of just seeing the most recent atime for a given url, you
will see multiple entries.
If the completion model would stay the same, just keep it and update the
filter pattern rather than instantiating a new model each time the
pattern changes.
Instead set this on inidividual categories, as that is where it actually
gets used. This makes it easier for SqlCompletionCategory to reuse a
prepared query (as it gets the filter field names in its constructor).
Trying to read from the sql database from another process was flaky.
This adds a debug-dump-history command which is used by the history BDD
tests to validate the history contents.
It outputs history in the old pre-SQL text format, so it might be
useful for those who want to manipulate their history as text.
Returning "next" was no longer possible as the SQL query does not fetch
more items than necessary. This is solved by using a start time, a
limit, and an offset. The offset is needed to prevent fetching duplicate
items if multiple entries have the same timestamp.
Two of the history tests that relied on qute://history were changed to
rely on qute://history/data instead to make them less failure-prone.
The history completion query is extended to pick only the most recent item for
a given url.
The tests in test_models now check for ordering of elements.
The old implementation was looping through the whole history list, which for
SQL was selecting every row in the database. The history benchmark was taking
~2s. If this is rewritten as a specialized SQL query, the benchmark takes
~10ms, an order of magnitude faster than the original non-SQL implementation.
Vulture exposed the following dead code:
- AppendLineParse was only used for reading the history text file, which is now
a sql database (and the import code for the old text file is simpler and does
not need a complex line parser)
- async_read_done is no longer used as importing the history text file is
synchronous (and should only happen once)
- config._init_key_config is unused as it was moved to keyconf.init
Calling sql.init() in version.version() would replace the existing sql
connection and cause a crash when accessed by opening qute://version.
Now version relies on sql already being initted, and app.py inits sql early if
the --version arg is given.
Turns out historyContains was getting called for the webkit backend multiple
times when the browser starts. This was calling `url in history`, which was
enumerating the entire history as `__contains__` was not defined.
Instead of skipping bad history lines during the import to sql, fail hard. We
don't want to delete the user's old history file if we couldn't parse all of
the lines.
Now that sql is only used for history (not quickmarks/bookmarks) a number of
functions are no longer needed. In addition, primary key support was removed as
we actually need to support multiple entries for the same url with different
access times. The completion model will have to handle this by selecting
something like (url, title, max(atime)).
This also fixes up a number of tests that were broken with the last few
sql-related commits.
If qutebrowser detects a history text file when it starts
(~/.local/share/qutebrowser/history by default on Linux), it will import this
file into the new sqlite database, then delete it.
The read is done as a coroutine as it can take some time.
Instead of reading sqlite history from a file and storing it in an in-memory
database, just directly use an on-disk database. This resolves#755, where
history entries don't pop in to the completion menu immediately as they are
still being read asynchronously for a few seconds after the browser starts.
Deleting a history entry should do nothing, but we want a test to ensure this
and get 100% branch coverage for urlmodel.
This also un-skips the bookmark/quickmark tests.
Instead of add_list and add_sqltable, the completion model now supports
add_category, and callees either pass in a SqlCategory or ListCategory. This
makes unit testing much easier.
This also folds CompletionFilterModel into the ListCategory class.
Now all completion models are of a single type called CompletionModel.
This model combines one or more categories. A category can either be a
ListCategory or a SqlCategory.
This simplifies the API, and will allow the use of models that combine simple
list-based and sql sources. This is important for two reasons:
- Adding searchengines to url completion
- Using an on-disk sqlite database for history, while keeping bookmarks and
quickmars as text files.
This was a performance optimization that shouldn't be needed with the new SQL
history backend. This also removes support for the LIMIT feature from SqlTable
as it only existed to support web-history-max-items.
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.
