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
This just forwards canFetchMore and fetchMore to the underlying tables.
It seems to be returning True and fetching in some cases (with a large
history), so I guess it is useful?
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)
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 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.
Turns out re.escape also escapes spaces, so we'd need to replace '(\\ )'
groups after escaping. At this point it's easier to just combine spaces
before escaping the pattern.
Fixes#1934.
Supersedes #1935.
Command completions for `:bind` and `:` will now show bindings for
aliases. The binding is only included if it is bound to that alias, not
if it is bound to the command the alias points to.
Returning a defaultdict made the caller's code look confusing, as it
wasn't clear why there wouldn't be a Keyerror in some cases. Instead,
let the caller explicitly use `get`.
Consolidate the logic used to generate the command completion category
into one place. This is shared by CommandCompletionModel,
HelpCompletionModel, and BindCompletionModel.
Hidden commands are not shown in command completion as they typically
would not be run directly. However, a user might still might like to see
help for them if, for example, they are writing a script or creating a
binding.
Addresses #1707.
Wire up the config change event to update command completion on
changing aliases, so the new aliases will be included.
Fixes#1814.
Currently we do not have tests at a high enough level to test whether
signals are wired up correctly to update completions.
Completion.empty existed to fill a slot in the old Command.completions
interface if the first positional arg had no completions but the second
did, as is the case for the `bind` command. Now that
`Command.completions` is replaced by `Command.get_pos_arg_info`, this
is no longer needed.
When a redirect occurs, the item is saved in history with a -r suffix
now. When opening qutebrowser that's picked up and the item is hidden
from completion.
The check `key.startswith('<') and key.endswith('>') is repeated many
times in code to check for a special key. Replace all these with a call
to the same function.
When showing the currently bound key in the misc column for command
completion, if the command has multiple bindings, show special bindings
(e.g. <ctrl-a>) after non-special bindings.
- Add a space after the comman for multiple binding suggestions.
- Use defaultdict(list) instead of defaultdict(lambda: [])
- Move the pylint comment back to the top of the class
Adds a title to the HistoryEntry class and includes it in the serialization
stuff. Not currently set from anywhere.
Not sure if anything more needs to be done to support non-ascii characters.
Everything works fine for me with unicode chars in url and title but
everything in my stack is utf-8.
All commands will be offered as completions for the <command> argument
of :bind.
Due to the way completers parse the command line, the following
bind --mode caret j
will throw off completions as 'caret' is treated as a positional arg in
terms of the argument count for completions.
In the above example, completion will be triggered for 'j' and no
completions will be given for the actual command.
bind --mode=caret j will complete correctly, though completions are not
filtered by the given mode.
I attempted an approach to filter the commands based on the mode but it
ended up being messy and flaky.
This worked fine with Python 3.5 but causes a circular import which is
hard to break with Python 3.4.
The original solution was to do @pyqtSlot(object), but that doesn't work
with PyQt 5.6 anymore...
Allows to use ctrl+d to close tabs from the buffer completion widget
when they are selected. Respects current tab settings like whether you
can close the last tab in a window.
Had to change the `rebuild()` method to use `setData()` when possible
because the selection was being lost if the whole model was being rebuilt.
Current problems are:
1) When opening a new window while you already the tab completion open on
one window a category is added for the new window but new rows in
that category aren't picked up. Interesting if you open a third
window then close the second window the completion display is now
correct... I can see that the model is being updated correctly but I
am not sure why that isn't propagating to the view. Not sure whether
it is worth looking into (further) either.
2) Bit of duplication of code, it iterates over the window registry
twice. Could put everything in one loop but then that would be
dependant on the current behaviour of the `tab_closed` signal being
called with the relevant `tabbed_browser` still existing but with the
`shutting_down` flag set.
3) I'm still using just the one `rebuild()` method and removing items from
the end then calling `setData` on everything rather than having special
`on_tab/window_closed` methods (or partial functions) that delete the
actual corresponding item. Because if I did that I would also have to
special case tab moves etc.
`buffer` takes either a tab index or a string and focuses the specified
tab. The index can be of the form [0-9]+ which will switch to the
relevant tab in the current window or [0-9]+/[0-9]+ (that is
win_id/index) which will focus the specified window before switching
tabs. If a string is passed the list of open tabs across all windows is
sorted based on title and url (just like in the completion widget) and
the top result is selected.
WebHistory now has a clear() method which is also a command
(history-clear) which clears the qutebrowser history using the new
lineparser clear() method and emits a cleared signal.
The completion model urlmodel connects to the WebHistory.cleared signal
and clears its history category completion list.
I am adding this as a temporary fix before #58 or #1051 get implemented.
Fixes#919.
There were two issues here:
- CompletionWidget didn't delete the old model when setting a new one. This
means filterAcceptsRow was called for models which aren't even used anymore.
- setChild was used instead of appendRow for the BaseCompletionModel, which
caused Qt to call filterAcceptsRow once for every item of the completion
model instead of only once.
