Previously FSAC displayed some but not all errors and always
rejected directories and devices. This has led most apps to ignore
response errors in open/save actions or show redundant messages.
Now FSAC displays all errors including fd failures and has the ability
to silence messages for directories, devices and ENOENT, which some
apps handle differently. Silenced directory and device errors now
return files on success.
A request's access mode is now stored in RequestData to format more
accurate error messages from the user's perspective.
Resolved promises don't require callback propagation so they're voided
If linking fails, we throw a JS exception, and if there's no execution
context on the VM stack at that time, we assert in VM::current_realm().
This is a hack to prevent crashing on failed module loads. Long term we
need to rewrite module loading since it has been refactored to share
code differently between HTML and ECMA262.
We were performing a check whether source pixels would fall into a
clipped rect too early. Since we already clamp the resulting source
coordinates to the clipped rect, we can just remove this code.
Box sampling is a scaling algorithm that averages all the pixels that
form the source for the target pixel. For example, if you would resize a
9x9 image to 3x3, each target pixel would encompass a 3x3 pixel area in
the source image.
Box sampling is a near perfect scaling algorithm for downscaling. When
upscaling with this algorithm, the result is similar to nearest neighbor
or smooth pixels.
For `IntRect`, we assume that the right/bottom edge is offset by minus
one. This obviously will not work for `FloatRect`, since those edges are
infinitely small.
Specialize `right()` and `bottom()` and add a `FIXME` to get rid of the
offset in the future.
Adds support for grid items with fixed size paddings. Supporting
percentage paddings will probably require to do second pass of tracks
layout: second pass is needed to recalculate tracks sizes when final
items sizes are known when percentage paddings are already resolved.
This generic stream wrapper performs checksum calculations on all data
passed through it for reading or writing, and is therefore convenient
for calculating checksums while performing normal data input/output, as
well as computing streaming checksums on non-seekable streams.
The implementation of this is naive enough so it can handle all 8-bit
CRC polynomials, of which there are quite a few. The table generation
and update procedure is MSB first, which is backwards from the LSB first
method of CRC32.
This change addresses the incorrect assumption that the available width
inside a grid item is equal to the width of the track it belongs to.
For instance, if a grid item has a width of 200px, the available width
inside that item is also 200px regardless of its column(s) base size.
To solve this issue, it was necessary to move the final resolution of
grid items to occur immediately after the final column track sizes are
determined. By doing so, it becomes possible to obtain correct
available width inside grid items while resolving the row track sizes.
These 2 are an actual separate types of syscalls, so let's stop using
special flags for bind mounting or re-mounting and instead let userspace
calling directly for this kind of actions.
The resolved property sets are stored with the element in a
per-pseudo-element array (same as for pseudo element layout nodes).
Longer term, we should stop storing this with elements entirely and make
it temporary state in StyleComputer somehow, so we don't waste memory
keeping all the resolved properties around.
This makes various gradients show up on https://shopify.com/ :^)
The goal here is to reduce the amount of WebContent client APIs that are
duplicated across every ViewImplementation. Across our three browsers,
we currently:
Ladybird - Mix some AK::Function callbacks and Qt signals to notify
tabs of WebContent events.
Browser - Use only AK::Function callbacks.
headless-browser - Drop most events on the floor.
Instead, let's only use AK::Function callbacks across all three browsers
to propagate events to tabs. This allows us to invoke those callbacks
directly from LibWebView instead of all three browsers needing to define
a trivial `if (callback) callback();` override of a LibWebView virtual
function. For headless-browser, we can simply not set these callbacks.
As a first pass, this only converts WebContent events that are trivial
to this approach. That is, events that were simply passed onto the tab
or handled without much fuss.
This is to match Browser, where ownership of all "subwidgets" is placed
on the tab as well. This further lets us align the web view callbacks to
match Browser's OOPWV as well, which will later let us move them into
the base LibWebView class.
The implementations of handle_web_content_process_crash and
take_screenshot are exactly the same across Browser and Ladybird. Let's
reduce some code duplication and move them to LibWebView.
This change makes grid items be responsible for their borders instead
of grid tracks which can not have borders itself.
There are changes in layout tests but those are improvements :)
This should keep the `read_some` function a bit flatter and shorter, and
make it easier to match the match type decoding process with the
specification.
1. Propagate calc() values from StyleProperties to ComputedValues.
2. Actually resolve calc() values when determining the used flex basis.
This makes the "support" section on https://shopify.com/ show up
correctly as a 2x2 grid (instead of 1x4). :^)
While inline content between floating elements was broken correctly,
text justification was still using the original amount of available
space (without accounting for floats) when justifying fragments.
This code now works in terms of *intrusion* by left and right side
floats into a given box whose insides we're trying to layout.
Previously, it worked in terms of space occupied by floats in the root
box of the BFC they participated in. That created a bunch of edge cases
since the code asking about the information wasn't operating in root
coordinate space, but in the coordinate space of some arbitrarily nested
block descendant of the root.
This finally allows horizontal margins in the containing block chain to
affect floats and nested content correctly, and it also allows us to
remove a bogus workaround in InlineFormattingContext.
This seems mostly harmless and matches what CSS expects from us at the
moment. Eventually our CSS font selection will become more sophisticated
and stop relying on Gfx::FontDatabase for things like this, but for now
it's a simple stopgap that lets websites do "font-family: arial" :^)
