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 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)
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.
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.
TestProcFs expects to be able to stat its stdout and stderr. The new
ProcFS implemetnation properly forwards the symlinks for
/proc/pid/fd/[1,2] to the temporary file that we had unlinked prior to
spawning the process. However, this makes it so that a normal stat on
the symlink to that file fails (as expected). Move the unlink to after
we've waited on the child, so that we know it won't be trying any funny
business with its stdout/stderr anymore.
This test program heavily pulls from the JavaScriptTestRunner/test-js,
but with a twist. Instead of loading JavaScript files into the current
process, constructing a JS environment for them, and executing test
suites/tests directly, run-tests posix_spawns each test file.
Test file stdout is written to a temp file, and only dumped to console
if the test fails or the verbose option is passed to the program. Unlike
test-js, times are always printed for every test executed for better
visibility in CI.
Split out the functionality to gather multiple tests from the filesystem
and run them in turn into Test::TestRunner, and leave the JavaScript
specific test harness logic in Test::JS::TestRunner and friends.
This introduces a new DOMTreeJSONModel, which provides the Model for the
InspectorWidget when the Browser is running using the
OutOfProcessWebView.
This Model is constructed with a JSON object received via IPC from the
WebContentServer.
Add `inspect_dom_tree` to WebContentServer and 'did_get_dom_tree' to
WebContentClient.
These two async methods form a request & response for requesting a JSON
representation of the Content's DOM tree.
This method builds a JSON object representing the full state of the
DOM tree.
The JSON that is built will be used for building the DOM Inspector
widget for the OutOfProcessWebView.
This fixes the build by hiding the problem from the compiler, but it's
a useful change in and of itself anyway.
A malloc/free per every mouse event is pretty annoying, especially when
we can actually avoid it.
This will cause a problem when `NonnullRefPtr<T>::operator T*` will be
declared as RETURNS_NONNULL. Clang emits a warning for this pointless
null check, which breaks CI.
