Linux accepts both -r and -R, but the BSDs only like -R, and
dR POSIX also only mentions -R. So make -R the canonical flag.
Keep -r available as an alias for -R.
This patch implements the "remove irrelevant boxes" and "generate
missing child wrappers" parts of table fixup.
"Generate missing parents" is left as a task for our future selves.
Else, there's tons of "-- Set runtime path of" spam at build time,
with apparently no way of disabling the build noise other than turning
of rpaths. If the dynamic loader uses them at some point, we probably
want to set them through cflags/ldflags instead of through cmake's
built-in thing anyways, for that reason.
It seems like both BFC and IFC can have absolutely positioned children.
It's a bit strange, but consider the following HTML:
<html><body>foobar<img style="position: absolute"></body></html>
In such a document, the <img> element is an absolutely positioned child
of a block-level element (<body>) with no block-level children.
An IFC is established for <body>, and needs to handle layout for <img>.
Various whitespace-related issues have been fixed, and support for the
different CSS white-space values is improved enough that I think we can
stop doing the hack where we just prune whitespace nodes from the tree
and actually let them show up.
This is a nice step forward for correctness with the slight downside of
cluttering up layout tree dumps with tons of whitespace text nodes.
But hey, that's the web we know & love. :^)
Fixes#4427.
The StyleResolver can find the specified CSS values for the parent
element via the DOM. Forcing everyone to locate specified values for
their parent was completely unnecessary.
Layout nodes now only carry CSS computer values with them. The main
idea here is to give them only what they need to perform layout, and
leave the rest back in the DOM.
Put all the inherited members in one struct and all the non-inherited
ones in another.
This makes it clear which is which, and also makes it easy to copy all
the inherited values while ignoring the non-inherited ones.
Another step towards not having to carry the full specified style with
us everywhere. This isn't the ideal final layout, since we're mixing
computed and used values a bit randomly here, but one step at a time.
We shouldn't reject indexed palette PNGs just because they have fewer
palette entries than the bit depth allows. Instead, we need to check
for OOB palette accesses and fail the decode *then*.
When changing the mouse cursor (e.g when hovering over a link) we now
only change the InProcessWebView's override cursor instead of setting
the cursor at the window level.
This fixes an issue where the I-beam or hand cursors would somehow
"escape" from the web view and over to other widgets.
This patch adds a global (per-process) filter list to LibWeb that is
used to filter all outgoing resource load requests.
Basically we check the URL against a list of filter patterns and if
it's a match for any one of them, we immediately fail the load.
The filter list is a simple text file:
~/.config/BrowserContentFilters.txt
It's one filter per line and they are simple glob filters for now,
with implicit asterisks (*) at the start and end of the line.
Instead of each window having a bool flag that says whether that window
is currently active, have a pointer to the active window on the app
object instead.
When constructing a GlobalObject, it has to pass itself as the global
object to its own Shape. Since this is done in the Object constructor,
and Object is a base class of GlobalObject, it's not yet valid to cast
"this" to a GlobalObject*.
Fix this by having Shape store the global object as an Object& and move
Shape::global_object() to GlobalObject.h where we can at least perform a
valid static_cast in the getter.
