Most coredumps contain large amounts of consecutive null bytes and as
such are a prime candidate for compression.
This commit makes CrashDaemon compress files once the kernel finishes
emitting them, as well as adds the functionality needed in LibCoreDump
to then parse them.
This way it's easier to find the right window when many are open at the
same time, as all buttons share a limited amount of horizontal space and
titles get truncated quickly.
Because it's what it really is. A frame is composed of 1 or more samples, in
the case of SerenityOS 2 (stereo). This will make it less confusing for
future mantainability.
In single process mode, the browser will display a page's favicon in
both the location bar and tab. This adds the same support for multi-
process mode.
We kept a backpointer from the Menu to its containing MenuBar, but it
was not used for anything so let's remove it.
Since all menus have the same font now, there's no need to track a
separate "title font".
This leaves menu applets running but invisible, and that's a regression
we need to take care of obviously. But not today, because it's getting
too late.
This patch begins the transition away from the global menu towards
per-window menus instead.
The global menu looks neat, but has always felt clunky, and there
are a number of usability problems with it, especially in programs
with multiple windows.
You can now call GUI::Window::set_menubar() to add a menubar to
your window. It will be specific to that one window only.
This takes up a lot of space if it is not used, and the default image
does not give value. Therefore, we hide the image widget if an invalid
image is passed.
This commit puts all of the remaining pieces in place. This adds a
mechanism to update the text, title, and icon of an image. If an image
is not provided, the default ladybug will be shown.
This will allow us to later query the notifications from a connection
and safely update it without exposing it to any other applications, as
it is session based.
The previous names (RGBA32 and RGB32) were misleading since that's not
the actual byte order in memory. The new names reflect exactly how the
color values get laid out in bitmap data.
This small commit should allow to specify additionnal parameters in the
form of URL queries, when opening a file via a "file://" url through the
LaunchServer.
Previously the page background was always draw relative to the viewport
instead of following with the content. This should eventually become
an opt-in mode (via CSS "background-attachment") but for now let's have
the default behavior be that backgrounds scroll with content.
Also take this opportunity to move the background painting code from
the two web views to a shared location in InitialContainingBlockBox.
Because the z-order changes we not only need to recompute occlusions
but we also need to mark the screen area of the previous and new
highlighted window as dirty.
Fixes#5599
When a mousewheel scroll event isn't handled by the web content
itself (e.g. an overflowed box or similar), the event needs to get
passed back up to the OutOfProcessWebView.
This is basically just for consistency, it's quite strange to see
multiple AK container types next to each other, some with and some
without the namespace prefix - we're 'using AK::Foo;' a lot and should
leverage that. :^)
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
Also, only mark the menu bar item as opened if a menu was actually
opened through the menu bar.
These changes allow a menu to be used both in the menu bar as well
as a context menu.
Fixes#5469
A window repaint may change the alpha value, resulting in a different
hit test outcome. In those cases, re-evaluate the cursor hit testing
after a window was painted, and update the cursor if needed.
We didn't add buttons for certain window types or states when the
window was created, but when a window with a button changed its
state to where we would not have created the button, we didn't
remove the existing button.
Tool windows are secondary windows with a smaller title bar. The sit on
the layer above normal windows, and cannot be minimized.
These are intended for complex yet non-modal interactions with the
content of a primary window, such as find/replace windows, property
windows, etc.
Minimum window size can now be customised and set at runtime via the
SetWindowMinimumSize WindowServer message and the set_minimum_size
LibGUI::Window method. The default minimum size remains at 50x50.
Some behind-the-scenes mechanics had to be added to LibGUI::Window to
ensure that the minimum size is remembered if set before the window is
shown. WindowServer sends a resize event to the client if it requests a
size on create that's smaller than it's minimum size.
We need to first deliver the mouse event and possibly the double click
event and record these facts. Then, we need to iterate all global
tracking listeners and deliver the mouse event (but not the double
click event) to any such listener, unless they already had these
events delivered.
Fixes#4703
LookupServer can now itself server as a DNS server! To service DNS clients, it
uses the exact same lookup logic as it does for LibIPC clients. Namely, it will
synthesize records for data from /etc/hosts on its own (you can use this to
configure host names for your domain!), and forward other questions to
configured upstream DNS servers. On top of that, it implements its own caching,
so once a DNS resource record has been obtained from an upstream server,
LookupServer will cache it locally for faster future lookups.
The DNS server part of LookupServer is disabled by default, because it requires
you to run it as root (for it to bind to the port 53) and on boot, and we don't
want either by default. If you want to try it, modify SystemServer.ini like so:
[LookupServer]
Socket=/tmp/portal/lookup
SocketPermissions=666
Priority=low
KeepAlive=1
User=root
BootModes=text,graphical
and enable server mode in LookupServer.ini like so:
[DNS]
Nameservers=...
EnableServer=1
If in the future we implement socket takeover for IP sockets, these limitations
may be lifted.
Where it belongs, alongside the /etc/hosts check. The inner lookup() method is
really about talking to a specific DNS server.
Also, don't bail out on a empty name. An empty DNSName is actually '.' — a
single dot — aka the DNS root.
