This is equivalent to 58d6a2d0192b7860ecb2edb4aa5d36b389213a15 but for
the left shift operation.

This is not guaranteed to work at all

When calculating the horizonal size of a section in
`HeaderView::visible_section_range()`, the horizonal padding is now
correctly taken into account.
This fixes header missalignment issues in Spreadsheet, SystemMonitor
and maybe also the playlist tab of SoundPlayer

This changes the previously static s_debug_info_cache to a member
variable. This is required so the cache is not kept alive if the
Backtrace object is destroyed.
Previously, the cache object would keep alive MappedFile objects and
other data, resulting in CrashReporter and CrashDaemon using more than
100 MB of memory even after the Backtrace objects have been destroyed
(and the data is thus no longer needed). This was especially the case
when handling crashes from Browser (due to libweb.so and libjs.so).
Due to this change, object_info_for_region has been promoted to a
instance method. It has also been cleaned up somewhat.

They're not yet properly supported.

The pthread_exit() function doesn't return and is marked as such.
|
|
These were already properly aligned (as far as I can tell).

Starting usermode threads doesn't currently work on x86_64. With this
stubbed out we can get text mode to boot though.

Currently, the DOM Inspector stores a numeric ID for each DOM node. This
is used to look up the data for that node in the JSON representation of
the DOM. The method to do this search performs a depth-first search
through the JSON value, and is invoked quite frequently.
Instead, we can just store a pointer to the JSON value in the index, and
avoid this search altogether. This is similar to how the IPWV stores a
pointer to the DOM node.
|
|
To improve the performance of the DOM Inspector when the Browser is run
in multi-process mode, do not create copies of the JSON values sent via
IPC when searching for a model index. Methods that are guaranteed to
return a value now return a reference. Methods that do not have such a
guarantee return a pointer (rather than an Optional, because Optional
cannot hold references).
The DOM Inspector performs well at first, but will start lagging again
once the tree is expanded a few nodes deep and/or with many nodes
visible in the tree.

Specifically, we immediately return an empty string when `this` is an
empty string, instead of wasting time in a loop doing nothing N times.
|
|
Specifically, we now cast to a u32 instead of an i32, as well as use
the validity check required by the specification. The current
constructor is still quite far from the specification, as we directly
set the indexed properties' length instead of going through the Array's
overriden DefineOwnProperty. (and as a result the checks imposed by the
ArraySetLength abstract operation)

When the type is guaranteed to be known, there's no need to use RTTI.

This avoids construction of LexicalPath objects.
|
|
|
|
This moves the path canonicalization from the LexicalPath constructor to
canonicalized_path. This allows canonicalized path to no longer
construct a LexicalPath object and initialize all its member variables.
|
|
This removes the default constructor of LexicalPath, and subsequently
modifies all its users to accommodate the change.
|
|
This replaces the current LexicalPath::append() API with a new method
that returns a new LexicalPath object and doesn't touch the this-object.
With this, LexicalPath is now immutable. It also adds a
LexicalPath::parent() method and the relevant test cases.

This changes the m_parts, m_dirname, m_basename, m_title and m_extension
member variables to StringViews onto the m_string String. It also
removes the m_is_absolute member in favour of computing if a path is
absolute in the is_absolute() getter. Due to this, the canonicalize()
method has been completely rewritten.
The parts() getter still returns a Vector<String>, although it is no
longer a const reference as m_parts is no longer a Vector<String>.
Rather, it is constructed from the StringViews in m_parts upon request.
The parts_view() getter has been added, which returns Vector<StringView>
const&. Most previous users of parts() have been changed to use
parts_view(), except where Strings are required.
Due to this change, it's is now no longer allow to create temporary
LexicalPath objects to call the dirname, basename, title, or extension
getters on them because the returned StringViews will point to possible
freed memory.
|
|
The LexicalPath instance methods dirname(), basename(), title() and
extension() will be changed to return StringView const& in a further
commit. Due to this, users creating temporary LexicalPath objects just
to call one of those getters will recieve a StringView const& pointing
to a possible freed buffer.
To avoid this, static methods for those APIs have been added, which will
return a String by value to avoid those problems. All cases where
temporary LexicalPath objects have been used as described above haven
been changed to use the static APIs.

Since this is always set to true on the non-default constructor and
subsequently never modified, it is somewhat pointless. Furthermore,
there are arguably no invalid relative paths.

There is a check in map_bus_region to make sure we don't pointlessly
remap the bus region if the previous mapping was for the same bus.
This is tracked with `m_mapped_bus`.
However, nothing was actually updating `m_mapped_bus`, and it is
initialised to 0. This means that if we start with a device on bus 0,
the read in data will be valid. If we map say bus 1 then bus 0 again,
the map for bus 0 will now be ignored and invalid data will be read in.
Fixed by updating `m_mapped_bus` with the currently mapped bus.

This can be accessed after init via lspci.

This patch adds a PasswordBox. At the moment, it's simply a TextBox with
it's substitution code point set to '*', and the undo and redo actions
disabled.
|
|
This patch adds the member variable m_substitution_code_point to
GUI::TextEditor. If non-zero, all gylphs to be drawn will be substituted
with the specified code point. This is mainly needed to support a
PasswordBox.
While the primary use-case is for single-line editors, multi-line
editors are also supported.
To prevent repeated String construction, a m_substitution_string_data
members has been added, which is an OwnPtr<Vector<u32>>. This is used as
a UTF-32 string builder. The substitution_code_point_view method uses
that Vector to provide a Utf32View of the specified length.

This patch fixes a bug where double-clicking on a word in a TextEditor
with syntax highlighting would also select an additional character after
the word. This also simplifies the logic for double- and
triple-clicking.

This patch brings all of LibVideo up to the east-const style in the
project. Additionally, it applies a few fixes from the reviews in #8170
that referred to older LibVideo code.

The TreeParser requires information about a lot of the decoder's
current state in order to parse syntax tree elements correctly, so
there has to be some communication between the Decoder and the
TreeParser. Previously, the Decoder would copy its state to the
TreeParser when it changed, however, this was a poor choice. Now,
the TreeParser simply has a reference to its owning Decoder, and
accesses its state directly.

This patch adds compressed header parsing to the VP9 decoder (section
6.4 of the spec). This is the final decoder step before we can start to
decode tiles.
|

This hack allows self-test mode run-tests-and-shutdown.sh to give
TestProcFs a stat(2)-able /proc/self/fd/0. For some reason, when
stdin is a SerialDevice, /proc/self/fd/0 will be a symlink to the device
as expected, but, calling realpath or stat on /proc/self/fd/0 will error
out. realpath will give the string from Device::absolute_path() which
would be something like "device:4,64 (SerialDevice)". When VFS is trying
to resolve_path so that we can stat the file, it would bail out on this
fake-y path.
Change the fake path (that doesn't show up when you ls a device, nor
when checking the devices tab in SystemMonitor) from the major/minor
device number and class_name() to /dev/device_name(). There's probably
a very hairy yak standing behind this issue that was only discovered due
to the ProcFS rework.
