The use of this HashMap looks very spooky, but let's at least use
finalize when cleaning them up on destruction to make things slightly
less dangerous looking.
While investigating an issue with Unicode::Segmenter (the result of
which is passed to functions in this file), this missing include was
causing clangd to be unable to find non-virtual implementations.
This commit begins to implement the track processing model. When the
`src` attribute is updated, we now fetch the given source file.
Currently, we always fire an `error` event once fetching is completed,
as we don't support processing the fetched data.
Invalidation for adopted style sheets was broken because we had an
assumption that "active" style sheet is always attached to
StyleSheetList which is not true for adopted style sheets. This change
addresses that by keeping track of all documents/shadow roots that own
a style sheet and notifying them about invalidation instead of going
through the StyleSheetList.
This replaces the old `OAEP` implementation with one backed by OpenSSL.
The changes also include some added modularity to the RSA class by
making the `RSA_EME` and `RSA_EMSE` for encryption/decryption and
signing/verifying respectively.
It used to be that the caller would supply a buffer to write the output
to. This created an anti-pattern in multiple places where the caller
would allocate a `ByteBuffer` and then use `.bytes()` to provide it to
the `PKSystem` method. Then the callee would resize the output buffer
and reassign it, but because the resize was on `Bytes` and not on
`ByteBuffer`, the caller using the latter would cause a bug.
Additionally, in pretty much all cases the buffer was pre-allocated
shortly before.
`current_property_id()` is insufficient to determine if a quirk is
allowed. For example, unitless lengths are allowed in certain
properties, but NOT if they are inside a calc() or other function. It's
also incorrect when we are parsing a longhand inside a shorthand. So
instead, replace that with a stack of value-parsing contexts. For now,
this is either properties or CSS functions, but in future can be
expanded to include media features and other places.
This lets us disallow quirks inside functions, like we're supposed to.
It also lays the groundwork for being able to more easily determine
what type a percentage inside a calculation should become, as this is
based on the same stack of contexts.
Previously, a crash would occur when attempting to throw an error in
this case because the method used to create the exception tried to get
the current realm from the execution context stack, which is empty. The
realm is now passed explicitly when constructing the error, avoiding
the crash.
Instead of always reporting a colno and lineno of zero try and use the
values from the Error object that may be provided, falling back to the
source location of the invocation if not provided. We can definitely
improve the reporting even more, but this is a start!
Also update this function to latest spec while we're in the area.
This isn't a full fix, as the paint function does not handle this
either. But instead of getting the bitmap from the image source
immediately, follow the spec a bit more closely by creating the
CanvasPatern object with the ImageSource directly.
Fixes a crash for the 5 included WPT tests.
We added these methods to propagate OOM errors at process startup, but
we longer fret about these tiny OOM failures. Requiring that these init
methods be called prohibits using these strings in processes that have
not set up a MainThreadVM. So let's just remove them and initialize the
strings in a sane manner.
In doing so, this also standardizes how we initialize strings whose C++
variable name differs from their string value. Instead of special-casing
these strings, we just include their string value in the x-macro list.
This makes it more convenient to use the 'relvant agent' concept,
instead of the awkward dynamic casts we needed to do for every call
site.
mutation_observers is also changed to hold a GC::Root instead of raw
GC::Ptr. Somehow this was not causing problems before, but trips up CI
after these changes.
URL::basic_parse has a subtle bug where the resulting URL is not set
to valid when StateOveride is provided and the URL parser early returns
a valid URL.
This has not surfaced as a problem so far, as the only users of the
state override API provide an already valid URL buffer and also ignore
the result of basic parsing with a state override.
However, this bug surfaces implementing the URL pattern spec, which as
part of URL canonicalization:
* Provides a dummy URL record
* Basic URL parses that URL with state override
* Checks the result of the URL parser to validate the URL
While we could set URL validity on every early return of the URL parser
during state override, it has been a long standing FIXME around the code
to try and remove the awkward validity state of the URL class. So this
commit makes the first stage of this change by migrating the basic
parser API to return Optional, which also happens to make this subtle
issue not a problem any more.
This matches the behavior of other browsers, which always set the dirty
checkedness flag when setting checkedness, except when setting the
`checked` content attribute.
