Before this patch, when having the initial spinbox color value
(Color::White), if you changed the color value in the vertical color
picker it didn't update the spinbox's colors.
This is fixed by manually calling update() in the color picker's
onchange() handler if the new color is equal to the previous color,
which is the case in the initial spinbox's case as it will always be
white unless it is changed (and won't be affected by the vertical
color picker).
I added a NOTE in the source to explain this "opaque" update() call :))

This tackles a FIXME, but also makes sense to implement only now that
the SecurityHandler logic has been fixed. When a Document is created an
automatic attempt is made to provide the empty string as the password;
even if this attempt failed the SecurityHandler still reported it had a
user password, hence we never arrived to the VERIFY_NOT_REQUIRED line
this commit is changing.
|
|
When an attempt is made to provide the user password to a
SecurityHandler a user gets back a boolean result indicating success or
failure on the attempt. However, the SecurityHandler is left in a state
where it thinks it has a user password, regardless of the outcome of the
attempt. This confuses the rest of the system, which continues as if the
provided password is correct, resulting in garbled content.
This commit fixes the situation by resetting the internal fields holding
the encryption key (which is used to determine whether a user password
has been successfully provided) in case of a failed attempt.
|
|
With the StandardSecurityHandler the Length item in the Encryption
dictionary is optional, and needs to be given only if the encryption
algorithm (V) is other than 1; otherwise we can assume a length of 40
bits for the encryption key.

I confused myself when implementing this, plus I tested using pages that
had errors in pages 1 and 2, so the index and the number of the page
(internally represented as 0-indexed) was always the same. When opening
files with errors on higher pages it became evident that there was an
issue with how I was reading the errors per page from the corresponding
ModelIndex object.

Adapt BMPImageDecoderPlugin to support BMP images included in ICOns.
ICOImageDecoderPlugin now uses BMPImageDecoderPlugin to decode all
BMP images instead of it's own ad-hoc decoder which only supported
32 bpp BMPs.

Displays the current active Unicode block range, or, if multiple
glyphs are selected, their count. Clicking toggles the Unicode
block ListView.
|
|
Selections are always normalized when saving undo commands.
The restore_selection() function reverses this process so
negatively sized selections (created right-to-left) continue
to resize correctly with the keyboard when restored.
|
|
Fixes being teleported to the old location when scrolling on a
previously browsed range.

and when using unmodified arrows.

Previously the widget used a very rough estimate for visible glyphs
based on viewport and glyph areas. Now it simply figures rows times
columns with a two row overdraw to accommodate fractional glyphs
on either end of visible content. For KaticaRegular10, this ends up
reducing unnecessary glyph iterations during painting by about 30%.
|
|
Fixes a slightly oversized content rect and erroneous glyph outer
rect values. Increases glyph rect padding to guarantee at least 1px
between the focus rect and glyph.
|
|
|
|
Fixes crashing on invalid code points when creating selections
with the keyboard and applying actions to them.
Also adds Home/End key support for selections. Ctrl+Shift+{Home,End}
now extends the selection to the beginning or end of the active range,
respectively. Shift+{Home,End} extends the selection to the start or
end of the row. Alt+{Home,End} resets the selection and moves the
active glyph to the beginning or end of the active range.
|
|
Previously selection reset was ignored on active glyph change if the
old glyph equaled the new one. This was an intentional behavior that
allowed selections to resize by dragging the focused glyph, but has
proved more counterintuitive than useful.
Now the widget behaves like other text selection controls: selections
can be reset by clicking anywhere in them or shift can be held to
grow the selection.
|
|
This is a bogus size as the map must always have at least 1 glyph
selected, and it was causing occasional desync between selection
contents and the focused glyph when manipulating selections with
the keyboard.
|
|
Allows focus to be passed using the keyboard.
|
|
Provides a visual cue that arrow key input is shared between these
widgets.
|
|
|
|
|
|
The main motivation for this is to prefill an extension for user when
saving a new file.
|
|
This way we can get a compiler error about unhandled new language cases,
instead of a possible crash when running a program.
Also added a missing case to make it build now.
|
|
|
|
Before this patch, all key down events except arrow keys or WASD were
not propagated, so keyboard shortcuts in the application didn't work.
This patch fixes this :))

This patch makes use of a new "set_snake_base_color()" function to
change the snake's base color to the picked value.
|
|
This patch adds a m_snake_base_color variable which dictates the color
of the head of the snake and from which the rest of the snake color's
are derived from by darkening the base color.
|
|
This patch adds an action in the Snake's game menu that allows for easy
pausing/unpausing of the game state.
In order to do this, the commit adds new pause()/start() functions in
the SnakeGame class ;)

This fixes a few things I noticed whilst working on the inspector
for Ladybird.
1.
The computed and resolved values were being passed swapped around
from the inspect_dom_node() IPC call. I.e. computed values were
passed as resolved values and vice versa. This was then fixed by
swapping them again in the InspectorWidget (two errors canceled out).
2.
Resolved values were called "specified values" seemingly only in the
inspect_dom_node() IPC calls. This was a little confusing so I've
renamed them to back to "resolved values" for consistency.
3.
The inspector took and stored the DOM JSON strings unnecessarily,
all the models immediately parse the JSON and don't need the strings
to hang around.
|
|
Keeping these around can lead to use-after-frees and crashes.
|
|

|
Noticed this trying to inspect GitHub, you'd get a segfault due to the
parent node being null here.
|
|
Instead of avoiding overflow-checking builtins with AK_COMPILER_CLANG,
we can use the preprocessor's __has_builtin() mechanism to check if
they are available.

When we encounter an explicit timezone, we shift the time to UTC.
Because we rely on `mktime`, we need to shift it to the local time
before proceeding. If no explicit timezone is provided, local timezone
is assumed.
This fixes the "timezone-offset extension" LibJS test running on
machines with a non-UTC timezone offset.

This could aid debugging in many cases, and it doesn't break any
functionality, so let's ensure it's easier to understand in which way a
provided value is out of range.

This happens to be a sad truth for the VirtIOGPU driver - it lacked any
error propagation measures and generally relied on clunky assumptions
that most operations with the GPU device are infallible, although in
reality much of them could fail, so we do need to handle errors.
To fix this, synchronous GPU commands no longer rely on the wait queue
mechanism anymore, so instead we introduce a timeout-based mechanism,
similar to how other Kernel drivers use a polling based mechanism with
the assumption that hardware could get stuck in an error state and we
could abort gracefully.
Then, we change most of the VirtIOGraphicsAdapter methods to propagate
errors properly to the original callers, to ensure that if a synchronous
GPU command failed, either the Kernel or userspace could do something
meaningful about this situation.

The performance that we achieve from this technique is visually worse
compared to turning off this feature, so let's not use this until we
figure out why it happens.

...as long as `brew` is on the path and `brew --prefix e2fsprogs`
tells us where it is.
This is for people who don't have `"$(brew shellenv)"` in their .zshrc.

Without this, `serenity.sh run` fails with
gdbstub: current accelerator doesn't support guest debugging
on an intel mac.

layout_box() already has a non-const overload, so we don't need to
const_cast them anymore. This gets rid of 2 FIXMEs. :^)
