- After letting a LayoutNode handle a mouseup, re-do the hit test
since things may have changed.
- Make sure we always update the document's hovered node.
This was previously used to defer handling disconnections until the
next event loop iteration. We now achieve the same with simple use
of deferred_invoke(). :^)
This patch introduces IPC::Connection which becomes the new base class
of ClientConnection and ServerConnection. Most of the functionality
has been hoisted up to the base class since almost all of it is useful
on both sides.
This gives us the ability to send synchronous messages in both
directions, which is needed for the WebContent server process.
Unlike other servers, WebContent does not mind blocking on a response
from its client.
str{,n}casecmp is supposed to be *only* declared by strings.h, note the
trailing 's' in the filename.
We don't have any implementation for strlcat; using any strcat variants is
a bad idea anyway, given our implementation of AK::String.
TODO: Find a way to lint for declared-but-nowhere-defined functions.
I know, the tags don't actually matter. However, clang warns by default,
and instead of disabling the warning for clang I'd rather enable the warning
for gcc.
I decided to modify MappedROM.h because all other entried in Forward.h
are also classes, and this is visually more pleasing.
Other than that, it just doesn't make any difference which way we resolve
the conflicts.
This fixes two cases obj[expr] and obj[expr]() (MemberExpression and
CallExpression respectively) when expr throws an exception and results
in an empty value, causing a crash by passing the invalid PropertyName
created by computed_property_name() to Object::get() without checking it
first.
Fixes#3459.
This fixes two issues with running a TryStatement finalizer:
- Temporarily store and clear the exception, if any, so we can run the
finalizer block statement without it getting in our way, which could
have unexpected side effects otherwise (and will likely return early
somewhere).
- Stop unwinding so more than one child node of the finalizer
BlockStatement is executed if an exception has been thrown previously
(which would have called unwind(ScopeType::Try)). Re-throwing as
described above ensures we still unwind after the finalizer, if
necessary.
Also add some tests specifically for try/catch/finally blocks, we
didn't have any!
Interpreter::run() was so far being used both as the "public API entry
point" for running a JS::Program as well as internally to execute
JS::Statement|s of all kinds - this is now more distinctly separated.
A program as returned by the parser is still going through run(), which
is responsible for creating the initial global call frame, but all other
statements are executed via execute_statement() directly.
Fixes#3437, a regression introduced by adding ASSERT(!exception()) to
run() without considering the effects that would have on internal usage.
Errors like this became more likely due to the 'optimized' memory usage.
Also, this prevents the WindowServer from being killed by a goofy program
sharing an incomplete bitmap, and likely some other scenarios.
Indexed bitmaps used to allocate four times the required amount of memory.
Also, we should acknowledge that the underlying data is not always RGBA32,
and instead cast it only when the true type is known.
In all circumstances, this returned exactly the same thing as scanline_u8(),
so let's just remove the silly detour.
This does not add any new dependency on Bitmap-internals, because that already existed.
This broke in case of unterminated regular expressions, causing goofy location
numbers, and 'source_location_hint' to eat up all memory:
Unexpected token UnterminatedRegexLiteral. Expected statement (line: 2, column: 4294967292)
This makes PrintfImplementation usable with any sequence, provided that
a 'next element' function can be written for it.
Does not affect the behaviour of printf() and co.
After dispatching a "change" event due to the checked state being
modified, we may have been removed from the layout tree.
Make LayoutCheckBox protect itself to prevent this from crashing.
Also, add a little test page for checkboxes. :^)
This is implemented entirely inside LibWeb, there is no GUI::CheckBox
widget instantiated, unlike other input types. All input types should
be moved to this new style of implementation.
To implement form controls internally in LibWeb (necessary for multi
process forms), we'll need the ability to handle events since we can't
rely on LibGUI widgets anymore.
A LayoutNode can now override wants_mouse_events() and if it returns
true, it will now receive mousedown, mousemove and mouseup events. :^)
