Previously almost all fields were public and were directly accessed by
the Parser and CppComprehensionEngine.
This commit makes all fields of AST node types private. They are now
accessed via getters & setters.
With this patch we are finally done with section 6.4.X of the spec :^)
The only parsing left to be done is 6.5.X, motion vector prediction.
Additionally, this patch fixes how MVs were being stored in the parser.
Originally, due to the spec naming two very different values very
similarly, these properties had totally wrong data types, but this has
now been rectified.
Though technically block decoding calls into some other incomplete
methods, so it isn't functionally complete yet. However, we are
very close to being done with the 6.4.X sections :)
These elements were being used in the new tokens implementation, so
support for them in the TreeParser has been added.
Additionally, this uncovered a bug where the nonzero contexts were
being cleared with the wrong size.
This was required for correctly parsing more than one frame's
height/width data properly. Additionally, start handling failure
a little more gracefully. Since we don't fully parse a tile before
starting to parse the next tile, we will now no longer make it past
the first tile mark, meaning we should not handle that scenario well.
The class that was previously named Decoder handled section 6.X.X of
the spec, which actually deals with parsing out the syntax of the data,
not the actual decoding logic which is specified in section 8.X.X.
The new Decoder class will be in charge of owning and running the
Parser, as well as implementing all of the decoding behavior.
Additionally, this uncovered a couple bugs with existing code,
so those have been fixed. Currently, parsing a whole video does
fail because we are now using a new calculation for frame width,
but it hasn't been fully implemented yet.
Now TreeParser has mostly complete probability calculation
implementations for all currently used syntax elements. Some of these
calculation methods aren't actually finished because they use data
we have yet to parse in the Decoder, but they're close to finished.
With the progress made in the Decoder thus far, we have the ability
to support most of the syntax element counters in the tree parser.
Additionally, it will now crash when trying to count unsupported
elements.
If the device requires a flush and we modify the front buffer, we need
to flush those changes to the front buffer. This makes the flashing
work using the VirtIOGPU.
Also fix a minor bug where we flushed the front buffer instead of
the back buffer after flipping, which caused the VirtIOGPU to not work
as expected when using the SDL backend and disabling buffer flipping.
The spec requires a flush after setting the new buffer resource id,
which is required by QEMUs SDL backend but not the GTK backend. This
brings us in line with the spec and makes it work for the SDL backend.
Previously m_constrain_angle could end up not being reset if the
keyup-event was lost, for example when opening a dialog. Instead check
the modifiers in on_mousemove().
...for the non-success state. This fixes a crash when parsing dates with
the year -1, as we would assert successful parsing ("year != -1").
Mixing Optional and -1 seems worse and more complicated than just using
Optional for all the values, so I did that instead.
It is defined as follows:
21.4.3.1 Date.now ( )
https://tc39.es/ecma262/#sec-date.now
The now function returns the time value designating the UTC date and
time of the occurrence of the call to now.
"Time value" is defined as:
21.4.1.1 Time Values and Time Range
https://tc39.es/ecma262/#sec-time-values-and-time-range
An ECMAScript time value is a Number, either a finite integral
Number representing an instant in time to millisecond precision or
NaN representing no specific instant.
By flooring the value we match the behavior in the Temporal proposal's
Temporal.ZonedDateTime.prototype.epochMilliseconds getter:
4. Let ms be RoundTowardsZero(ℝ(ns) / 10^6).
With that being defined as:
13.30 RoundTowardsZero ( x )
https://tc39.es/proposal-temporal/#sec-temporal-roundtowardszero
1. Return the mathematical value that is the same sign as x and
whose magnitude is floor(abs(x)).
This is makes the last of the currently 15 Temporal tests in test262
work, which compares Temporal.now.instant() with Date.now() :^)
The way overlay was drawn is not the correct way to achieve window
transparency in selection mode. With this change, shot window becomes
truely transparent.
Previously, moving the cursor over items in an item view would cause it
to repaint itself completely. Now we only repaint the two affected
items (the old hovered item and the new hovered item.)
All regex flags supported by LibJS currently correspond to a LibRegex
option, but this is not the case for the RegExp.prototype.hasIndices
proposal, which is handled entirely in RegExpBuiltinExec. Remove the
flag mapping to prepare for this. This incurs a bit of an optimization
loss in the flag getters, as we now do a substring search, but we can
revisit the getter implementation if it becomes an issue.
Making use of the new FileSystemAccessServer we are able to use
unveil without restricting our ability to open and save files.
A file argument will be unveiled automatically however all other files
require user action via the FileSystemAccessServer to gain access.
Adds new service FileSystemAccessServer which allows programs to
request a file descriptor for any file on the file system.
The user can be prompted to choose the path with a FilePicker, or the
path can be provided by the application which will show a MessageBox
showing the pid and name of the calling process and allows the user to
approve or deny the request.
