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.
The System V ABI for both x86 and x86_64 requires that the stack pointer
is 16-byte aligned on entry. Previously we did not align the stack
pointer properly.
As far as "main" was concerned the stack alignment was correct even
without this patch due to how the C++ _start function and the kernel
interacted, i.e. the kernel misaligned the stack as far as the ABI
was concerned but that misalignment (read: it was properly aligned for
a regular function call - but misaligned in terms of what the ABI
dictates) was actually expected by our _start function.
We did not call the history change callback after switching to the
alternate screen buffer, which caused the scrollbar to not change its
maximum value. If we already had lines in the scrollback buffer, this
meant that we could drag the scrollbar, which then tried to access
non-existent lines from the scrollback.
Fixes#8581
Thicker lines are drawn by filling rectangles along the path.
Previously these rectangles used the points as their top left corner.
This patch changes it to use the points as the center of the rectangles
which makes the PixelPaint line tool feel a lot more natural. :^)
Our RegExpBuiltinExec implementation differed from the spec in some
areas such as handling of the sticky/global flags and updating the
lastIndex property.
If the sticky flag is set, the regex execution loop should break
immediately even if the execution was a failure. The specification for
several RegExp.prototype methods (e.g. exec and @@split) rely on this
behavior.
This allows passing an existing RegExp object (or an object that is
sufficiently like a RegExp object) as the "pattern" argument of the
RegExp constructor.
As an abstraction, RegExpExec should not assume that the RegExp object
being used is "this" object. Instead, it should only interact with the
provided object.
This prepares for some methods, such as @@split, which invoke RegExpExec
with a secondary RegExp object.
This adds the ALWAYS_INLINE attribute to unicode_view_width. Also, it
cleans up the BitmapFont::view() code a little bit. This should help
performance of this hot code. Because the call to the width() methods is
a virtual dispatch, it doesn't help to inline the width() methods
themselves.
This patch addresses the following issues:
- size resetting to 1 when switching from bitmap font size 10 to TTF
- size resetting to 1 when incrementing spinbox from 8 to 9
- selection mode not being set on m_size_list_view selection change
Previously, we only checked the intermediate bytes for those escape
sequences that performed different operations based on their
intermediate bytes. This lead to a crash when `CSI ?1001 r` was
incorrectly parsed as `CSI Pt ; Pb r` (note the missing question mark),
as seen in #8559.
Not all of the TypedArray prototype methods and accessors require
detached buffer validation (only the ones who call ValidateTypedArray)
so this behaviour was split from typed_array_from and the usage was
updated per the spec in each location.
As we've opted to make these inline functions and not macros, let's at
least make sure that the users don't *observe* multiple definitions of
these functions.
create_from() casts the value to a 64 bit integer and then creates two
words from it, which is not necessary if we only pass values to it that
fit into a single word (32 bit integer).
Also make them use UnsignedBigInteger as the previously missing SBI
divided_by() overload is now implemented.
