This looks at three things:
- if the type has a typedef `AllowOwnPtr', respect that
- if not, disallow construction if both of `ref()' and `unref()' are
present.
Note that in the second case, if a type only defines `ref()' or only
defines `unref()', an OwnPtr can be created, as a RefPtr of that type
would be ill-formed.
Also marks a `Performance' to explicitly allow OwnPtrs.
Two issues:
- throw_exception() with ErrorType::InstanceOfOperatorBadPrototype would
receive rhs_prototype.to_string_without_side_effects(), which would
ASSERT_NOT_REACHED() as to_string_without_side_effects() must not be
called on an empty value. It should (and now does) receive the RHS
value instead as the message is "'prototype' property of {} is not an
object".
- Value::instance_of() was missing an exception check after calling
has_instance_method, to_boolean() on an empty value result would crash
as well.
Fixes#3930.
This adds a new MetaProperty AST node which will be used for
'new.target' and 'import.meta' meta properties. The parser now
distinguishes between "in function context" and "in arrow function
context" (which is required for this).
When encountering TokenType::New we will attempt to parse it as meta
property and resort to regular new expression parsing if that fails,
much like the parsing of labelled statements.
This is a bit nicer for two reasons:
- The absence of line number/column information isn't based on 'values
are zero' anymore but on Optional's value
- When reporting syntax errors with position information other than the
current token's position we had to store line and column ourselves,
like this:
auto foo_start_line = m_parser_state.m_current_token.line_number();
auto foo_start_column = m_parser_state.m_current_token.line_column();
...
syntax_error("...", foo_start_line, foo_start_column);
Which now becomes:
auto foo_start= position();
...
syntax_error("...", foo_start);
This makes it easier to report correct positions for syntax errors
that only emerge a few tokens later :^)
By having the "is this a use strict directive?" logic in
parse_string_literal() we would apply it to *any* string literal, which
is incorrect and would lead to false positives - e.g.:
"use strict" + 1
`"use strict"`
"\123"; ({"use strict": ...})
Relevant part from the spec which is now implemented properly:
[...] and where each ExpressionStatement in the sequence consists
entirely of a StringLiteral token [...]
I also got rid of UseStrictDirectiveState which is not needed anymore.
Fixes#3903.
If you try to do this (e.g "mv directory directory"), sys$rename() will
now fail with EDIRINTOSELF.
Dr. POSIX says we should return EINVAL for this, but a custom error
code allows us to print a much more helpful error message when this
problem occurs. :^)
Views would previously require that an item be selected before it could
be dragged. This patch makes us consider initiating a drag immediately
after the view has been selected, without requiring a mouseup event in
between.
This is sad (since it would be nice to preserve the cursor+selection)
but until we implement persistent model indexes, this at least prevents
us from keeping a stale cursor index.
`DOM::XMLHttpRequest` now checks if the requested URL has the same
`Origin` as the requesting `Document`. If the requested URL is in
violation of SOP the request is rejected and an "error" `DOM::Event`
is dispatched.
Base/res/fonts/CsillaThin7x10.font was renamed to
Base/res/fonts/CsillaRegular10.font in 5abc03d, breaking the default
styles of <code> and <pre>.
The font lookup should still find a font variant when a non-existent
weight is specified, but that's another issue for another day.
The previous approach (keeping track of the current source position
manually) was only working for single line sources (which is fair
considering this was developed for Browser's JS console).
The new approach is much simpler: append token trivia (all whitespace
and comments since the last token), then append styled token value.

B.3.4 FunctionDeclarations in IfStatement Statement Clauses
The following augments the IfStatement production in 13.6:
IfStatement[Yield, Await, Return] :
if ( Expression[+In, ?Yield, ?Await] ) FunctionDeclaration[?Yield, ?Await, ~Default] else Statement[?Yield, ?Await, ?Return]
if ( Expression[+In, ?Yield, ?Await] ) Statement[?Yield, ?Await, ?Return] else FunctionDeclaration[?Yield, ?Await, ~Default]
if ( Expression[+In, ?Yield, ?Await] ) FunctionDeclaration[?Yield, ?Await, ~Default] else FunctionDeclaration[?Yield, ?Await, ~Default]
if ( Expression[+In, ?Yield, ?Await] ) FunctionDeclaration[?Yield, ?Await, ~Default]
This production only applies when parsing non-strict code. Code matching
this production is processed as if each matching occurrence of
FunctionDeclaration[?Yield, ?Await, ~Default] was the sole
StatementListItem of a BlockStatement occupying that position in the
source code. The semantics of such a synthetic BlockStatement includes
the web legacy compatibility semantics specified in B.3.3.
Now we (almost) verify all the sites we browse.
Certificate verification failures should not be unexpected, as the
existing CA certificates are likely not complete.
This API is only used for HttpRequest, but replicated in GeminiRequest
without an actual user, so remove it and construct the job like the rest
of the protocols.
This returns true if the widget has focus, or if one of its descendant
widgets does. Use this in StackWidget and TabWidget.
This also fixes HackStudio crashing on startup in StackWidget, due to
running before the window has a focused widget.
When computing the chain of focusable widgets in a window, only include
each widget once (to avoid loops) and resolve focus proxies immediately
instead of lazily. This prevents the focus from getting stuck when
cycling backwards and hitting a proxy that points forward.
When opening a new window, we'll now try to find a suitable widget for
initial focus by picking the first available mouse-focusable one.
Whenever you press the tab key in a window with no focused widget,
we'll attempt to find a keyboard-focusable widget and give it focus.
This should make all applications keyboard-interactive immediately
without having to manually place focus with the mouse.
This one is a bit sketchy. While a window is inactive, none of its
widgets are considered focused (Widget::is_focused() will return false)
but this caused programmatic changes of the active widget in a tab
or stack widget to fail focus propagation from old child to new child.
Work around this by checking against Window::focused_widget() directly
instead of asking Widget::is_focused().
You can now focus a TabWidget by tabbing (with the keyboard!) to it.
Once focused, you can switch the active tab by pressing the left/right
keyboard keys.
Every widget now has a GUI::FocusPolicy that determines how it can
receive focus:
- NoFocus: The widget is not focusable (default)
- TabFocus: The widget can be focused using the tab key.
- ClickFocus: The widget can be focused by clicking on it.
- StrongFocus: Both of the above.
For widgets that have a focus proxy, getting/setting the focus policy
will affect the proxy instead.
A player can no longer move the King piece into any position on
their home rank if the move would place the King in check.
A player can also no longer ignore a check position when in check
by a pawn on their home rank. The player must now resolve the check
during their move.
B.1.3 HTML-like Comments
The syntax and semantics of 11.4 is extended as follows except that this
extension is not allowed when parsing source code using the goal symbol
Module:
Syntax (only relevant part included)
SingleLineHTMLCloseComment ::
LineTerminatorSequence HTMLCloseComment
HTMLCloseComment ::
WhiteSpaceSequence[opt] SingleLineDelimitedCommentSequence[opt] --> SingleLineCommentChars[opt]
Fixes#3810.
