Instead of having a nested enum within a struct, use the macro
AK_ENUM_BITWISE_OPERATORS to add all the convienent has_flag free
functions and such for ease of use.
The FIXME here describes an old constraint on JS Interpreters which no
longer holds. It hails from a time when we had the global object and
JS realm attached to the document.
The proper abstract operations on Navigable and TraversableNavigable are
not quite ready to call from Navigation. With this commit all of the
user-facing APIs of Navigation are in place, and the stage should be set
to implement the parts of the navigation and traversal AOs that need to
interact with the Navigation object.
This is intended to annotate conversions from unknown floating-point
values to CSSPixels, and make it more obvious the fp value will be
rounded to the nearest fixed-point value.
In general it is not safe to convert any arbitrary floating-point value
to CSSPixels. CSSPixels has a resolution of 0.015625, which for small
values (e.g. scale factors between 0 and 1), can produce bad results
if converted to CSSPixels then scaled back up. In the worst case values
can underflow to zero and produce incorrect results.
The invariants for these property getters are supposed to be checked by
the has_entries_and_events_disabled AO, but we don't have all the
plumbing hooked up between Navigables and Navigation yet.
Add a test to make sure that these methods don't assert when calling
them on a fresh page.
The resolution is simply 1dppx * device pixel ratio.
This makes high resolution images show up on https://apple.com/
when running on a high-DPI display. :^)
The implementation is incomplete, because our Navigable::navigate
implementation is missing the navigationAPIState parameter. We also
don't have Navigables hooked up completely enough to guarantee that a
fully active document that is not being unloaded always has a Navigable.
This is used by both Navigable and Navigation, so let's put it in
Navigable. Also add a missing AK/String include to make clangd happier
with the Navigable file.
Every property in an IDL dictionary is implied to be optional, unless it
is marked as required. If a dictionary is passed to a method with
optional, but it has at least one required or defaulted member, the
bindings will skip the optionality of the parameter and always pass a
struct with the required parameters filled in.
We were previously setting the end position of attribute names in self-
closing HTML tags to the end of the attribute value. To illustrate the
previous behavior, consider this tag and its attribute's start and end
positions (shown inclusively below):
<meta charset="UTF-8" />
^ name start
^ value start
^ value end
^ name end
Rather than setting the end position of the attribute name when we parse
the closing slash, ensure the end position is already set while we are
in the AttributeName state. We now have:
<meta charset="UTF-8" />
^ name start
^ name end
^ value start
^ value end
The tokenizer unit test has been extended to test these positions.
To illustrate the previous behavior, consider these tags and their start
and end positions (shown inclusively below):
Start tag: End tag:
<span> </span>
^ start ^ start
^end ^end
The start position of a tag is the first ASCII-alpha code point after
the opening brace. The start position of a close tag is the slash just
before the first ASCII-alpha code point. And the end position of both
is the closing brace. So the opening brace is not included in the
emitted tag, but the closing brace is. And the end tag including the
slash is an oddity that had to be worked around in its only use case
(syntax highlighting).
We now consistently exclude the braces from the emitted tag, and also
exclude the slash from the end tag, so that it does not need to be
accounted for in syntax highlighting. That is, we now have:
Start tag: End tag:
<span> </span>
^ start ^ start
^end ^end
The tokenizer unit test has been extended to test these positions.
`DeprecatedString::to_int` calls `StringUtils::convert_to_int`
internally. However, the integer parsing is not done in an HTML
spec-compliant way. For example, `colspan="2;"` is valid according to
the spec. But, with the current implementation, we will fail to parse
"2;", and instead fall back to using 1 as the colspan value.
This patch changes the `HTMLTableCellElement::col_span` and
`HTMLTableCellElement::row_span` methods to use the
`Web::HTML::parse_non_negative_integer` function that will parse the
attribute value in an HTML spec-compliant way.
We have code inside LibWeb that uses the
`AK::StringUtils::convert_to_uint`and `AK::StringUtils::convert_to_int`
methods for parsing integers. This works well for the most part, but
according to the spec, trailing characters are allowed and should be
ignored, but this is not how the `StringUtil` methods are implemented.
This patch adds two new methods named `parse_integer` and
`parse_non_negative_integer` inside the `Web::HTML` namespace that uses
`StringUtils` under the hood but adds a bit more logic to make it spec
compliant.
This event is the star of the show, and the main way that web content
can react to either programmatic or user-initiated navigation.
All of the fun algorithms will have to come later though.
This API is how JavaScript can manipulate the new Navigable concepts
directly. We are still missing most of the interesting algorithms on
Navigation that do the actual navigation steps, and call into the
currently WIP navigable AOs.
This enum is used in many Navigation API classes, so stick it in its own
IDL file. However, we have no way to ask the BindingsGenerator to create
just an enum class that's not defined in an IDL file without an
``interface`` class at the top level, so implement the expected enum
and stringification method manually.
We never implemented this for History::pushState/popState, and now that
we're working on the Navigable changes, we don't need this legacy entry
with its legacy name.
Add the seralization and URL validation steps, but skip the actual
navigation for now. This might cause more pages to throw exceptions
when trying to push state that contains objects that we don't know how
to serialize.
With this change, elements that want to receive viewport rect updates
will need to register on document instead of the browsing context.
This change solves the problem where a browsing context for a document
is guaranteed to exist only while the document is active so browsing
context might not exit by the time DOM node that want to register is
constructed.
This is a part of preparation work before switching to navigables where
this issue becomes more visible.
Fixes stack-use-after-return bug found by ASAN that happens when
`response` reference captured by `process_response` is modified
after navigation has been canceled.
