Previously Welcome relied on a bogus executable key value to disable
startup. This always printed an error on login and littered the config
file with a useless entry. Adding/removing the group as needed seems
a bit nicer.
Plumbs synchronous calls for adding and removing group entries to
config files. This is useful for services like SystemServer which
default to group names for executable paths, and for removing all
keys at once.
I thought the spec listing out the elements again was an oversight, but
it isn't, as simply inverting "is_actually_disabled" makes :enabled
apply to every element.
Previously we only considered an element disabled if it was an <input>
element with the disabled attribute, but there's way more elements that
apply with more nuanced disabled/enabled rules.
This check happens very often in LibGUI code. 25% of time spent
layouting the emoji input dialog was wasted on RTTI. Adding a simple
fast_is<Widget>() melts almost all of that away.
If a flex item is itself a flex container, we were previously lying when
asked if the item created a BFC. It creates an FFC, so stop lying about
this in FormattingContext::creates_block_formatting_context().
We were using `>=` instead of `>` when checking if a float with a given
width could fit in the available space. If the width was an exact match,
we rejected it! Oops :^)
If the 2D transform in effect is just a simple translation, we don't
need to draw into a temporary bitmap and then transform it. We can
just translate the painter. :^)
I couldn't find anything in the specs about this, but GMail uses
empty generated boxes (`::before` and `::after` with `content: ""`)
inside a flexbox container in order to vertically center things.
The flexbox spec tells us to not generate flex items for empty
*anonymous* boxes, so we continue not doing that, but generated boxes
(any pseudo-element box) now always produce a flex item. This probably
isn't perfect either, and we'll have to revisit it for stuff like
`::first-letter`.
Let's not assume the containing block has a paintable box just because
someone is calling set_needs_display(). It can just be a no-op in that
case, and nobody gets hurt.
Instead of formatting contexts flailing around to figure out from the
"inside" how much space is available on the "outside", we should
provide the amount of available space in both axes as an input to run().
This basically means that when something creates a nested formatting
context, the parent context is responsible for telling the nested context
how much space is available for layout. This information is provided
immediately when invoking run().
Note that this commit doesn't pass accurate values in all cases yet.
This first step just makes it build, and passes available values in some
cases where getting them was trivial.
Previously, changing the time format caused Taskbar to crash.
This commit also simplifies TaskbarWindow::config_string_did_change()
so that it is in line with the changes made to
Calendar::config_string_did_change().
Fixes#15384
New actions in the Layer Menu allows for the creation of a new layer
from the current selection. Layers can be made by copying the
selection or cutting it from the current layer. The new layer will be
sized to the bounding box of the selection. The newly produced layer
will be added to the layer stack.
URL had properly named replacements for protocol(), set_protocol() and
create_with_file_protocol() already. This patch removes these function
and updates all call sites to use the functions named according to the
specification.

This inserts some CSS and JS to make images in Markdown documents which
are wider than the viewport, become shrink-to-fit. Clicking on these
toggles them between shrink-to-fit and full size.
Anyone who displays Markdown documents using LibWeb gets this
functionality for free! That's Browser, Help, and Welcome's README
display.
The tzname array stores the abbreviated names of the current time zone
when in standard and daylight time. These abbreviations are ambiguous;
a single abbreviation often maps to multiple time zones. For example,
EST is used by America/New_York and America/Detroit, and CST could be
the abbreviation of Central Standard Time or China Standard Time.
Instead, we mimic a subset of how both ICU and Howard Hinnant's "date"
library determines the current time zone. First, we try to parse the TZ
environment variable. If that fails, or isn't set, we try to resolve the
/etc/localtime symbolic link. On most Linux systems and on macOS, this
is a link to the current TZDB file in use.
If all of the above fails, we fall back to UTC.
In addition to changing the uid, the method also changes the gid and
properly sets groups. So this patch will also mitigate the security
issue of `pls`.
