Derivatives of Core::Object should be constructed through
ClassName::construct(), to avoid handling ref-counted objects with
refcount zero. Fixing the visibility means that misuses like this are
more difficult.
The old versions were renamed to JS_DECLARE_OLD_NATIVE_FUNCTION and
JS_DEFINE_OLD_NATIVE_FUNCTION, and will be eventually removed once all
native functions were converted to the new format.
Per spec, the initial containing block (ICB) should have the size of the
viewport. We have only done this for the width until now, since we had
no way to express scrollable overflow.
This patch adds Layout::Box::m_overflow_data, an optional struct that
can hold on to information about a box's overflow. Then we have BFC
set the ICB up with some scrollable overflow instead of sizing it to fit
its content vertically.
This fixes a number of broken layouts where correctness depends on
having the appropriate ICB height.
We now set the realm (twice) on every console input. This can probably
be avoided if we use two executing contexts one for the website the
other for the console.
This achieves a similar behavior but is not really nice and not really
spec like.
This added check matches CientConnection::js_console_input and makes
sure the webcontent process doesn't crash if the console is opened
while no page is available (like in a file not found situation)
Some content cause a lot of paint invalidations (e.g someone drawing to
a <canvas> repeatedly) and we don't need to spam the client about this.
Instead, accumulate a dirty rect, and send it once per event loop step.
Prior this commit we were always dereferencing the image bitmap pointer,
even if it was null, which resulted in a crash when trying to open
the context menu when an image wasn't loaded.
Closes: #10178
This is in preparation for implementing JS scrolling functions, which
specify both x and y scrolling deltas. The visible behavior has not
changed.
Also, moved the "mouse wheel delta * 20" calculation to the
`EventHandler` since the JS calls will want to work directly in pixels.
This patch removes the following WebContent IPC calls, which are no
longer used:
- `Server::js_console_initialize()`
- `Client::did_js_console_output()`
With this patch, we now initialize the `WebContentConsoleClient` as soon
as the Page has loaded, instead of waiting for the Console Window to be
shown. This finally lets us see log messages that happened before the
window was opened! :^)
However, it is not perfect. Waiting until the page has loaded means we
lose any messages that happen *during* page load. Ideally we would
initialize the WCCC when the page *starts* loading instead, but it
requires that the page has a document and interpreter assigned and
accessible. As far as I can tell with my limited knowledge, this is not
the case until the page has completed loading.
The `WebContentConsoleClient` now keeps a list of console messages it
has received, so these are not lost if the ConsoleWidget has not been
initialized yet.
This change does break JS console output, but only until the next
commit. :^)
This patch introduces three new IPC calls for WebContent:
- `Client::did_output_js_console_message(index)`:
Notifies the client that a new console message was logged.
- `Server::js_console_request_messages(start_index)`:
Ask the server for console messages starting at the given index.
- `Client::did_get_js_console_messages(start_index, types, messages)`:
Send the client the messages they requested.
This mechanism will replace the current
`Client::did_js_console_output()` call in the next few commits. This
will allow us to display messages in the console that happened before
the console was opened.
`$0` is a helpful variable in other browsers' JS consoles, which points
to whichever DOM Node is currently selected in the DOM Inspector. And
now we have it too! :^)
ConsoleGlobalObject is used as the global object when running javascript
from the Browser console. This lets us implement console-only functions
and variables (like `$0`) without exposing them to webpage content. It
passes other calls over to the usual WindowObject so any code that would
have worked in the webpage will still work in the console. :^)
This is the IPC version of `Document::set_inspected_node()`, using a
node ID.
We return the inspected node's style properties as JSON, so that the DOM
Inspector can immediately display them.
This patch adds OutOfProcessWebView::run_javascript(StringView).
This can be used by the OOPWV embedder to execute arbitrary JavaScript
in the top-level browsing context on the WebContent process side.
