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.
People are commonly asking about a package manager in
serenity. This patch adds an answer the FAQ, explaining
why there is no need for packages as well as different
possible ways to add or remove software installed on the
system.
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
This makes sure that scroll_into_view is not called when not necessary,
or when m_layers is empty, which previously caused a crash upon
removing the last layer.
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.
We've had a half-arsed port of libuv inside the cmake port, but let's
just port it properly.
Note that this pins a specific commit (which is currently the latest
commit in their default branch).
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.
- Use a simple pthread_mutex_t instead of bringing in headers from
LibThreading just to get a mutex.
- Use a normal mutex instead of a recursive one.
- Remove redundant locking in realloc().
