Normally, assigning to e.g document.body.onload will forward to
window.onload. However, in a detached DOM tree, there is no associated
window, so we have nowhere to forward to, making this a no-op.
The bulk of this change is making Document::window() return a nullable
pointer, as documents created by DOMParser or DOMImplementation do not
have an associated window object, and so must be able to return null
from here.
The default canvas size is 300x150 pixels. If the element or document
we are trying to screenshot for the WebDriver is not at least that size,
then we will create a canvas that is wider or taller than the actual
element we are painting, resulting in a bunch of transparent pixels
falling off the end.
This fixes 14 WPT css/CSS2/floats tests that we run in CI, and
presumably a ton of other reftests in the WPT test suite.
This prevents us from returning an 'unrecognized capability' error when
a WebDriver client sends us a proxy capability. We still don't actually
support setting or returning a non-empty proxy capability, though.
We just don't choke on the input capability request from the server.
This patch also doesn't actually validate the input proxy requests.
`JsonValue::to_byte_string` has peculiar type-erasure semantics which is
not usually intended. Unfortunately, it also has a very stereotypical
name which does not warn about unexpected behavior. So let's prefix it
with `deprecated_` to make new code use `as_string` if it just wants to
get string value or `serialized<StringBuilder>` if it needs to do proper
serialization.
In a bunch of cases, this actually ends up simplifying the code as
to_number will handle something such as:
```
Optional<I> opt;
if constexpr (IsSigned<I>)
opt = view.to_int<I>();
else
opt = view.to_uint<I>();
```
For us.
The main goal here however is to have a single generic number conversion
API between all of the String classes.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).

Since 2023-09-08, Clang trunk has had a bug which causes a segfault when
evaluating certain `requires` expressions inside templated lambdas.
There isn't an imminent fix on the horizon, so let's work around the
issue by specifying the type of the offending lambda arguments
explicitly.
See https://github.com/llvm/llvm-project/issues/67260
This required dealing with a *lot* of fallout, but it's all basically
just switching from DeprecatedFlyString to either FlyString or
Optional<FlyString> in a hundred places to accommodate the change.
Saving vector of local variables names in ECMAScriptFunctionObject
will allow to get a name by index in case message of ReferenceError
needs to contain a variable name.
Fixes the bug that currently we don't ever close webdriver client
connection socket when header "Connection: keep-alive" is specified.
This allows to run more WPT tests without running out of free file
descriptors :)
Before execute_async_script supported returning value from script to
/execute/async caller only if script returns promise that resolves into
returned value. This change fixes execute_async_script to also support
returning value to caller using callback that is always passed to
script as a last argument.
That's what this class really is; in fact that's what the first line of
the comment says it is.
This commit does not rename the main files, since those will contain
other time-related classes in a little bit.
Due to 582c55a, both `must_set()` and `set()` should be providing the
same behavior. Not only is that a reason to remove `must_set()`, but
it also performs erroneous behavior since it inserts an element at
a specified index instead of modifying an element at that index.
Some of these are allocated upon initialization of the intrinsics, and
some lazily, but in neither case the getters actually return a nullptr.
This saves us a whole bunch of pointer dereferences (as NonnullGCPtr has
an `operator T&()`), and also has the interesting side effect of forcing
us to explicitly use the FunctionObject& overload of call(), as passing
a NonnullGCPtr is ambigous - it could implicitly be turned into a Value
_or_ a FunctionObject& (so we have to dereference manually).
Currently significant portion of requests coming to WebDriver server
fails with error while parsing json body because requests are parsed
when they are not complete yet.
This change solves this by waiting for more data to arrive if HTTP
request parser found that there is not enough data yet to parse
the whole request.
In the future we would probably want to move this logic to LibHTTP
because this problem is relevant for any HTTP server.
This fix addresses issue where, if request headers contain
"Connection: keep-alive", we keep socket open without letting client
know that we support keep-alive connections. This can result in a
large number of open and unused sockets.
Similar to POSIX read, the basic read and write functions of AK::Stream
do not have a lower limit of how much data they read or write (apart
from "none at all").
Rename the functions to "read some [data]" and "write some [data]" (with
"data" being omitted, since everything here is reading and writing data)
to make them sufficiently distinct from the functions that ensure to
use the entire buffer (which should be the go-to function for most
usages).
No functional changes, just a lot of new FIXMEs.
Removal of dummy execution context in
9aca54091a caused a crash in
`execute_async_script` because of empty execution contexts stack
during `create_resolving_functions` call.
This changes the parameters parsed from a WebDriver HTTP request to
String for transferring over IPC. Conveniently, most locations these
were ultimately passed to only need a StringView.
This will allow easily surrounding operations that may fail due to OOM
with TRY. Note that we now also have to define a "normal" constructor
for WebDriver::Error in order to add the AK::Error constructor.
