Parsing last as an IPV4 number was not returning true in "ends with a
number" as the parsing of that part was overflowing. This means that the
URL is not considered to be an IPv4 address, and is treated as a valid
domain.
Helpfully, the spec also points out in a note that this step is
equivalent to simply checking that the last part ends with 0x followed
by only hex digits - which doesn't suffer from any overflow problem!
Arguably this is an editorial issue in the spec where this should be
clarified a little bit. But for now, fixing this fixes 3 sub tests in
WPT for:
https://wpt.live/url/url-constructor.any.html
Our heuristic was a bit too simplistic and would not run through the
ToASCII unicode algorithm which performs some extra validation. This
would cause invalid URLs that should fail to be parsed be mistakenly
accepted.
This fixes 8 tests in: https://wpt.live/url/url-constructor.any.html
We can't simply use the base URL as it may need to be modified in some
form. For example - for the included test, the fragment was previously
being included in the resulting URL.
This fixes 1 test on https://wpt.live/url/url-constructor.any.html
Instead of carrying the display list for a mask in each command that
might potentially be affected by "background-clip: text", this change
introduces a new AddMask command that is applied once for all
background layers within one box.
The new AddMask command includes a rectangle for the mask destination
that is translated by the corresponding scroll offset.
Fixes https://github.com/LadybirdBrowser/ladybird/issues/857
The spec didn't match how other browsers behave, and we dutifully did
what the spec said. A spec bug has been filed, so let's fix this locally
for now with a FIXME.
add_clip_rect() accepts a rectangle in viewport-relative coordinates,
so it must be translated by the enclosing scroll offset to be displayed
correctly inside a scrollable box.
This change fixes layering violation by moving to_px() calls to happen
before display list recording. Also it should make display list
recording a bit faster by resolving background properties beforehand.
This was a goof in cc55732332 which
resulted in the URL path getting double percent encoded. Since the path
already comes out percent encoded following the rules in the URL spec -
we don't need to percent encode again.
Fixes: #978
There were some extra steps in there which produced wrong results for
relative file URLs.
Fixes 7 test cases in: https://wpt.live/url/url-constructor.any.html
We also need to adjust the test results in TestURL. The behaviour tested
does not match how URL is specified to work as an absolute relative is
given.
Add a simple shell script to update the local clangd configuration
according to the type of build selected by the user. Include
documentation on where the script might be useful when building
under different configurations.
The check for:
```
if (start_index >= end_index)
return {};
```
To prevent an out of bounds when trimming the start and end of the input
of whitespace was preventing valid URLs (only having whitespace in the
input) from being parsed.
Instead, prevent start_index from ever getting above end_index in the
first place, and don't treat empty inputs as an error.
Fixes one WPT test on:
https://wpt.live/url/url-constructor.any.html
This doesn't seem like something we will neccessarily do in the URL
class anyway due to performance reasons - unless strictly needed (like
for the DOMURL implementation).
I previously believed there was no way a detached document should have
layout information, but it turns out there is a way: getComputedStyle().
So we need to account for cases where we have a layout node, but no
navigable, since that is a state we can get into at this moment.
Fixes#354
For the SVG <use> element, we want to support loading HTML documents
that have a SVG element inside of it pointed to by the URL fragment.
In this situation we would need to fetch and parse the entire document
in SharedImageRequest (so that we can still cache the SVGs). Rename
SharedImageRequest to SharedResourceRequest to make the class a little
more generic for future usecases.
This closer mirrors handle_failed_fetch, making the handling slightly
more clear to understand. It also means that we don't need to take a
strong reference to this on a successful SVG resource load.
...When loading images through SharedImageRequest.
There is a small behavioural difference here - handle_failed_fetch
clears the pending callbacks whereas handled_failed_decode was
previously not. This does not seem intentional, and appears like a bug.
Implementing it this way is _slightly_ simpler - and also means we
don't need to take a strong handle to this in the case of loading an
SVG image.
Web specs do not return through javascript percent decoded URL path
components - but we were doing this in a number of places due to the
default behaviour of URL::serialize_path.
Since percent encoded URL paths may not contain valid UTF-8 - this was
resulting in us crashing in these places.
For example - on an HTMLAnchorElement when retrieving the pathname for
the URL of:
http://ladybird.org/foo%C2%91%91
To fix this make the URL class only return the percent encoded
serialized path, matching the URL spec. When the decoded path is
required instead explicitly call URL::percent_decode.
This fixes a crash running WPT URL tests for the anchor element on:
https://wpt.live/url/a-element.html
Previously, calling `setProperty` or `removeProperty` from JS on a
CSSStyleDeclaration returned from `getComputedStyle()` would return
null. We now return a NoModificationAllowedError instead, which aligns
our implementation with the specification.
This also fixes a bug where task IDs were being deallocated from the
wrong IDAllocator. I don't know if it was actually possible to cause any
real trouble with that mistake, nor do I know how to write a test for
it, but this makes the bug go away.
Not every value in a StyleProperties will be non-null by the time we
perform `revert`, so let's make a specialized function for reverting a
property instead of using the path that requires the value to be
non-null.
