is_scroll_container() returns true for "overflow: hidden" which allows
programmable scrolling while is_scrollable() returns true only for
"overflow: scroll" and "overflow: auto" which allow scrolling only by
user interactions.
Fixes painting of nested nodes in scrollable containers by moving
painter's scroll offset translation from paint_node() to
before_children_paint() and after_children_paint().
WavWriter and the shot utility open files with this mode and never
truncate the files, which might leave some contents of a previous file
during overwriting.
This makes it easy to set up a realm, global object and root execution
context with a single call to LibJS. It will be useful to basically
everyone except LibWeb.
Build a grid snapped to device pixels and use it to construct the
rectangles for the cell edges, same as for collapsed borders. This is
especially important when border-spacing is set to 0 since it avoids
gaps between adjacent cells which have borders set.
Since SQLServer is inherently asynchronous, database statements can run
in parallel. Our `CookieJar` did not require synchronous actions on the
database for its cookies, resulting in cookies not being set
immediately. This resulted in a bug that could be exposed by setting
`document.cookie` and immediately querying its value, revealing that the
cookie was not yet persisted.
Solve this by requiring all database statements to be executed
synchronously. Ideally SQLServer has a mechanism to determine interquery
dependencies and blocks until dependent queries are fully executed, but
until we have that, this works around that limitation.
- Out-of-flow items should not affect grid layout
- "The static position of an absolutely-positioned child of a grid
container is determined as if it were the sole grid item in a grid
area whose edges coincide with the content edges of the grid
container."
When determining the precedence of the + and - operators, the parser
always returned the precedence using these operators in a binary
expression (lower than division!). The context of whether the operator
is used in a unary or binary expression must be taken into account.
This invariant is enforced by the fact that `NonnullGCPtr` can only be
constructed from references.
This commit fixes an instance where we compared a pointer to null after
we have already dereferenced it.
The compiler-generated copy constructor and copy assignment operator
already do the right thing (which is to simply copy the underlying
pointer).
The [Itanium C++ ABI][1] treats any class with non-trivial copy/move
constructors and destructors as non-trivial for the purposes of calls --
even if they are functionally identical to the compiler-generated ones.
If a class is non-trivial, it cannot be passed or returned in registers,
only via an invisible reference, which is worse for codegen. This commit
makes `{Nonnull,}GCPtr` trivial.
As the compiler can be sure that capturing a `GCPtr` by value has no
side effects, a few `-Wunused-lambda-capture` warnings had to be
addressed in LibWeb.
GCC seems to have a bug that prevents `ExceptionOr<Variant<GCPtr<T>>>`
from being implicitly constructed from `GCPtr<T>` after this change. A
non-invasive workaround is to explicitly construct the inner Variant
type.

This will help a lot with developing chromes for different UI frameworks
where we can see which helper classes and processes are really using Qt
vs just using it to get at helper data.
As a bonus, remove Qt dependency from WebDriver.
This method will be used by the package manager code to render an actual
Port's name to raw text as it is stored as relative URL currently in the
AvailablePorts.md file.
Previously, case-change operations did not produce visible results.
As of now, setting `m_chars_touched_in_the_middle` to a non-zero value
results in refreshing the whole line. So case-change operations now set
that variable (causing a line refresh) in order to produce visible
results as expected.
This method can be used to force the current process to sleep, waiting
for a debugger to attach. On attach, the debugger breaks at the callsite
directly.
This is tested on Linux and macOS, in Clion and also terminal gdb and
lldb.
The user can now save, load, and view calendars. A calendar is made up
of an array of events which are saved in a JSON file. In the future we
should implement the iCalendar standard instead of using a custom
format.
The features provided by these classes should be used eventually, but so
far we've been maintaining these classes for over 2 years without any
actual use. We can restore them when it comes time to actually use them.
