When launched with the new --enable-idl-tracing option, we now log
every call to web platform APIs declared via IDL, along with the
arguments passed.
This can be very helpful when trying to figure out what a site is
doing, especially if it's not doing what you'd expect.
When running with --log-all-js-exceptions, we will print the message
and backtrace for every single JS exception that is thrown, not just
the ones nobody caught.
This can sometimes be very helpful in debugging sites that swallow
important exceptions.
Before this change we had to keep session history on browser side to
calculate a url for back/forward/reload action.
Now, with a mature enough implementation of navigation algorithms from
the specification, there is no need to use
history on the browser side to calculate navigation URLs because:
- Traversable navigable owns session history that is aware of all
navigations, including those initiated by History API and Navigation
API
- TraversableNavigable::traverse_the_history_by_delta() uses
traversable's history to calculate the next URL based on delta, so
there is no need for UI to keep sesion history.
In the future, we will likely want to add a way to pull session history
from WebContent to make it browsable from the UI.
The previous name was extremely misleading, because the call is used for
pushing or replacing new session history entry on chrome side instead of
only changing URL.
Instead of treating reloading as a regular navigation by using
load_url(), now we invoke a navigable reloading algorithm implemented
from the spec.
Now both reloading triggered from UI and location.reload() will use the
same code path.
Currently the `<select>` dropdown IPC uses the option value attr to
find which option is selected. This won't work when options don't
have values or when multiple options have the same value. Also the
`SelectItem` contained so weird recursive structures that are
impossible to create with HTML. So I refactored `SelectItem` as a
variant, and gave the options a unique id. The id is send back to
`HTMLSelectElement` so it can find out exactly which option element
is selected.
This adds a button on the right side of the location bar to create a new
tab.
Ideally, we would actually use QTabWidget::setCornerWidget to put this
button in the tab bar. But it is surprisingly difficult to make that
look nice on all platforms. Even if we ignore macOS, the CSS to make the
button look right on KDE Plasma may not work well on Gnome. So for now,
this location next to the location bar is horizontally the same that it
would be in the tab bar at least.
We currently do this already when the last tab is closed via the ctrl-W
shortcut. Move the logic for this to BrowserWindow::close_tab so that we
also close the window when the tab is closed via its close button.
By default, Qt will grow the width of a tab button to fit the title text
of the tab. For long titles or file:// URLs, this looks rather bad. This
sets a min/max tab width to prevent such infinite growth.
To do this, we have to subclass both QTabWidget and QTabBar, because the
functions to be called/overridden are protected.
If the left-hand side of the tab is already occupied with an audio state
button, we would add a second button to the right-hand side. Prevent
that by checking if the occupant is our audio state button.
This implementation uses a really basic WebView to update stats once
a second. In the future it might make more sense to both move the
details into LibWebView, and to create a native widget for each platform
to remove the overhead of having an extra WebView.
On macOS, the "close tab" button is on the left, so we should place the
audio state button on the right to avoid conflict. Rather than an OS
ifdef, we do this by detecting if the left side is occupied.
We were errantly always referring to the active tab when the audio play
state changed, and when clicking a tab's audio state button, by way of
BrowserWindow::view().
It turns out we also can't copy / rely on the tab index provided to the
signal in any asynchronous context. If the tabs are rearranged, so are
their indices. Instead, capture a pointer to the tab of interest - this
should be safe as we wouldn't be able to click a tab's audio button if
that tab no longer exists.
With this change, we can click the audio button from any tab in the Qt
chrome, and re-arrange tabs at will. The AppKit and Serenity chromes do
not have this issue.
We already display a speaker icon on tabs which are playing audio. This
allows the user to click that icon to mute the tab, at which point the
icon is replaced with a muted speaker icon.
We would previously hide the icon when audio stopped playing. We now do
this only if the tab isn't muted. If it is muted, the muted speaker icon
remains on the tab so that the page isn't stuck in a muted state.
When audio begins playing, add a button to the left of the favicon with
a speaker icon to indicate which tab is playing audio. This button is
currently disabled, but in the future may be used to mute the tab.
This ensures we consistently show a favicon and that we update the title
to at least display the page URL when there isn't a <title> tag. We
would otherwise continue displaying the previous page's title.
This URL library ends up being a relatively fundamental base library of
the system, as LibCore depends on LibURL.
This change has two main benefits:
* Moving AK back more towards being an agnostic library that can
be used between the kernel and userspace. URL has never really fit
that description - and is not used in the kernel.
* URL _should_ depend on LibUnicode, as it needs punnycode support.
However, it's not really possible to do this inside of AK as it can't
depend on any external library. This change brings us a little closer
to being able to do that, but unfortunately we aren't there quite
yet, as the code generators depend on LibCore.
The code to convert a Gfx::IntPoint to a QPoint adjusted for the device
pixel ratio is a bit of a mouthful, and will be needed outside of Tab,
so move it to a helper that can be reused.
The Qt chrome currently handles all input events before selectively
forwarding those events to WebContent. This means that WebContent does
not see events like ctrl+c.
Here, we make use of LibWebView's input handling and wait for LibWebView
to inform the chrome that it should handle the event itself.
