ObservableArray inherits from JS::Array and overrides `internal_set`
and `internal_delete` to run an interceptor callback when an indexed
item is added or deleted.
This is for validating that a decoder with a weak or nonexistent
sniff() method thinks it can decode an image. This should not be
treated as an error.
No behavior change.
We are currently using Core::DateTime, which is meant to represent local
time. However, we are doing no conversion between the parsed time in UTC
and local time, so we end up comparing time stamps from different time
zones.
Instead, store the parsed times as UnixDateTime, which is UTC. Then we
can always compare the parsed times against the current UTC time.
This also lets us store parsed milliseconds.
Displaying a GML preview in HackStudio seems to be broken at the moment,
but this change will be needed once it does work again, so might as well
make it now, while I'm aware of the issue.
When in permissive mode, the ConfigServer will not treat reads and
writes to non-pledged domains as errors, but instead turns them into
no-ops: Reads will act as if the key was not found, and writes will do
nothing. Permissive mode must be enabled before pledging any domains.
This is needed to make GUI Widgets nicer to work with in GML Playground:
a few Widgets include reads and writes to LibConfig in order to load
system settings (eg, GUI::Calendar) or to save and restore state
(eg, GUI::DynamicWidgetContainer). Without this change, editing a
layout that includes one of these Widgets will cause GML Playground to
crash when they try to access config domains that are not pledged.
The solution used previously is to make Playground pledge more domains,
but not only does this mean Playground has to know about these cases,
but also that working on a layout file can alter the user's settings in
other arbitrary apps, which is not something we want.
By simply ignoring these config accesses, we avoid those downsides, and
Widgets will simply use the fallback values they already have to provide
to Config::read_foo_value().
Turns out the spec didn't mean that the whole range is populated,
but that one of these ranges is populated. So take the argmax.
As fallout, explicitly mark the Liberation fonts as nonsymbolic
when we use them for the 14 standard fonts. Else, we'd regress
"PostScrõpt", since the Liberation fonts would otherwise go down
the "is symbolic or doesn't have explicit encoding" codepath,
since the standard fonts usually don't have an explicit encoding.
As a fallout from _that_, since the 14 standard fonts now go down
the regular truetype rendering path, and since we don't implement
lookup by postscript name yet, glyphs not present in Liberation
now cause text to stop rendering with a diag, instead of rendering
a "glyph not found" symbol. That isn't super common, only an
additional 4 files appear for the "'post' table not yet implemented"
diag. Since we'll implement that soon, this seems fine until then.
...from try_create_for_raw_bytes().
If a plugin returns `true` from sniff but then fails when calling
its `create()` method, we now no longer swallow that error.
Allows `image` (and other places in the system) to print a more
actionable error if early image headers are invalid.
(We now no longer try to find another plugin that can also handle
the image.)
Fixes a regression from #20063 / #19893 -- before then, we didn't
do fallible work this early.
When placement position is found we always want to do following:
- Mark the occupied cells in the occupation grid
- Add the item to the list of placed items
Therefore, having helper that does both is useful
With this change we use the same code to resolve (start, end, span)
based on computed values in all cases:
- When only column is definite
- When only row is definite
- When both are definite
Moves the code that identifies (start, end, span) for a grid item into
a separate function. By doing so, we can eliminate the duplicated code
between the placement of grid items with definite columns and those
with definite rows.
This change omits some of the comments that reference the spec, as they
were largely irrelevant and unhelpful for making changes or diagnosing
issues.
Table wrappers don't quite behave the same as most elements, in that
their computed height and width are not meant to be used for layout.
Instead, we now calculate suitable widths and heights based on the
contents of the table wrapper when performing absolute layout.
Fixes the layout of

the comment.
Note no test here, because this early return involves HTTP-only cookies,
which we don't have the infrastructure to test (we would need to support
custom HTTP headers in tests).
It's no change in application behavior to have these objects owned by
the function-scope static map in Protocol.cpp, while allowing us to
remove some ugly FIXMEs from time immemorial.
Now that all input events are handled by LibWebView, replace the IPCs
which send the fields of Web::KeyEvent / Web::MouseEvent individually
with one IPC per event type (key or mouse).
We can also replace the ad-hoc queued input structure with a smaller
struct that simply holds the tranferred Web::KeyEvent / Web::MouseEvent.
In the future, we can also adapt Web::EventHandler to use these structs.
The Serenity chrome is the only chrome thus far that sends all input key
and mouse events to WebContent, including shortcut activations. This is
necessary for all chromes - we must give web pages a chance to intercept
input events before handling them ourselves.
To make this easier for other chromes, this patch moves Serenity's input
event handling to LibWebView. To do so, we add the Web::InputEvent type,
which models the event data we need within LibWeb. Chromes will then be
responsible for converting between this type and their native events.
This class lives in LibWeb (rather than LibWebView) because the plan is
to use it wholesale throughout the Page's event handler and across IPC.
Right now, we still send the individual fields of the event over IPC,
but it will be an easy refactor to send the event itself. We just can't
do this until all chromes have been ported to this event queueing.
Also note that we now only handle key input events back in the chrome.
WebContent handles all mouse events that it possibly can. If it was not
able to handle a mouse event, there's nothing for the chrome to do (i.e.
there is no clicking, scrolling, etc. the chrome is able to do if the
WebContent couldn't).
Animation::play_state() does not consider the fill state, and thus will
not return "Playing" for a fill-forward animation in the after phase.
It is still valid for paused, as pausing is not affected by the fill
mode.
All of this error propogation came from a single call to
HashMap::try_ensure_capacity! As part of the ongoing effort to ignore
small allocation failures, lets just assert this works. This has the
nice side-effect of propogating out to a few other classes.
Before this change, we only considering `grid-auto-flow` to determine
whether a row or column should be added when there was not enough space
in the implicit grid to fit the next unplaced item.
Now, we also choose the direction in which the "auto placement cursor"
is moved, based on the auto flow property.
This involves plumbing the perform the fetch hook argument throughout
all of the module fetch implementation AOs, where it was left as a FIXME
before.
With this change we can load module scripts in DedicatedWorkers.
This will be used to transfer information about the parent context to
DedicatedWorkers and future out-of-process Worker/Worklet
implementations for fetching purposes. In order to properly check
same-origin and other policies, we need to know more about the outside
settings than we were previously passing to the WebWorker process.
We previously used an empty optional to denote that a ReferrerPolicy is
in the default empty string state. However, later additions added an
explicit EmptyString state. This patch moves all users to the explicit
state, and stops using `Optional<ReferrerPolicy>` everywhere except for
when an option not being passed from JavaScript has meaning.
When buffering is enabled for the entire protocol request, it's possible
that the entirety of the file data might be available on the first read
of the pipe passed from RequestServer. If the file is then closed on the
RequestServer end, the client would never realize that the file is EOF
and call the user-provided on_finish callback.
By reading until there's an error, we expect to get an EAGAIN or similar
non-blocking pipe error message if there is still more data.
Also add a note to the Concepts header that the reason we have all the
strange concepts in place for container types is to work around the
language limitation that we cannot partially specialize function
templates.
