Instead of having to run queued promise jobs in LibWeb in various
places, this allows us to consolidate that into one function - this is
very close to how the spec describes it as well ("at some future point
in time, when there is no running execution context and the execution
context stack is empty, the implementation must [...]").
Eventually this will also be used to log unhandled exceptions, and
possibly other actions that require JS execution to have ended.
Instead of storing the function names (in a badly named Vector<String>)
and source ranges separately, consolidate them into a new struct:
TracebackFrame. This makes it both easier to use now and easier to
extend in the future.
Unlike before we now keep each call frame's current node source range
in the traceback frame next to the function name, meaning we can display
line and column numbers outside of the VM and after the call stack is
emptied.
This would return an empty value once it hits an exception check
otherwise. Considering that this mostly is used in situations where we
already *do* have an exception (traceback printing, for example), let's
make this easier for ourselves to use.
This is very similar to AK::TemporaryChange (and in fact replaces one
use of it), but since we can't directly set VM's m_exception from
outside of the VM, we need something more sophisticated.
Sometimes we need to temporarily remove the stored exception for some
other operation to succeed (e.g. anything that uses call(), as well as
get_without_side_effects()) and later restore it - the boilerplate code
required for this is annoying enough to justify a helper.
Correct the order we pass the arguments to the FileManager so
opening file:// URLs works.
The path is a positional argument that was passed after the flags.
We need to make sure the flags are passed before positional arguments.
Previously a Painter's m_clip_origin field was initialized to a
widget's window_relative_rect, which is not ensured to be within
the target rect.
m_clip_origin is normally not used for clipping, but after calling
clear_clip_rect the clip rect that IS used for clipping gets reset
to m_clip_origin (so an invalid state is entered).
Now the window_relative_rect will be clipped by the target rect
first, and will only then be used to initialize both the active
clip_rect and m_clip_origin.
The EXISTS expression is a bit of an odd-man-out because it can appear
as any of the following forms:
EXISTS (select-stmt)
NOT EXISTS (select-stmt)
(select-stmt)
Which makes it the only keyword expression that doesn't require its
keyword to actually be used. The consequence is that we might come
across an EXISTS expression while parsing another expression type;
NOT would have triggered a unary operator expression, and an opening
parentheses would have triggered an expression chain.
Currently, every parse_*_statement method ends by parsing a semi-colon.
This will prevent nested statements, e.g. a SELECT statement may be
nested in a CREATE TABLE statement. Move the semi-colon expectation up
and out of the individual statement parsers.
Another common semantic is parsing an identifier of the form
"schema_name.table_name" / "table_name". Add a helper to do this work.
This helper does not parse any optional alias after the table name.
some syntaxes specify an alias using the AS keyword, some let the AS
keyword be optional, and others just parse it as an identifier. So
callers to this helper will just continue parsing the alias however
they require.
A quite common semantic emerged for parsing comma-separated expressions:
consume(TokenType::ParenOpen);
do {
// do something
if (!match(TokenType::Comma))
break;
consume(TokenType::Comma);
} while (!match(TokenType::Eof));
consume(TokenType::ParenClose);
Add a helper to do the bulk of the while loop.
The Piano application used to perform very poorly due to unnecessary
draw calls. This is solved with two optimziations:
1. Don't draw the widgets as often as possible. The widgets are instead
at least updated every 150ms, except for other events.
2. Don't re-draw the entire piano roll sheet. The piano roll background,
excluding in-motion objects (notes, the play cursor), is only re-drawn
when its "viewport" changes.
A minor drawback of this change is that notes will appear on top of the
pitch labels if placed at the left edge of the roll. This is IMO
acceptable or may be changed by moving the text to the "foreground".
Using rsync is significantly faster when we're using an existing
image because we only have to copy files which are new or have
been updated. This cuts down the image creation time to about
a second or two assuming an old image exists.
This adds support for re-using and re-sizing existing disk images.
Disk images are checked with e2fsck prior to re-use and a new disk
image is automatically created when that check fails.
The native C++ < and > operators won't handle this correctly, so the
result was different depending on the order of arguments. This is now
fixed by explicitly checking for positive and negative zero values.
Fixes#6589.
This adds support for detecting incorrect version numbers and links
in the ports list.
Also, unlike before it doesn't parse the package.sh script but executes
it instead which allows us to detect syntax errors.
The 'syscall-arguments' positional arg being required was
breaking the scenario where the user just passes the
'--list-syscalls' argument.
Instead, make the argument not required, and manually handle
the error path our selves.
Closes: #6574
This new check will ensure that all commit message lines are at most 72
characters long, as well as ensure the commit title conforms to the
"Category: Brief description of what's being changed" format.
