Previously, all the code to add menus and actions was in main().
This was messy and didn't allow us to reference the actions from
SpreadsheetWidget, which is needed in order to add a toolbar.
This commit moves the menu and action adding code to method on
SpreadsheetWidget called initialize_menubar() which is based upon
applications such as TextEditor which have identically named methods
doing the same thing.
In additon, clipboard_action(), previouly a lambda in main(), has also
been made into a method on SpreadsheetWidget since it would otherwise
be destroyed when it goes out of scope. (This was previously avoided by
declaring the lambda in main() so it's always in scope.)

The way that transition avoidance (foo_without_transition) was
implemented led to shapes being unshareable and caused shape explosion
instead, precisely what we were trying to avoid.
This patch removes all the attempts to avoid transitioning shapes, and
instead *adds* transitions when changing an object's prototype.
This makes transitions flow naturally, and as a result we end up with
way fewer shape objects in real-world situations.
When we run out of big problems, we can get back to avoiding transitions
as an optimization, but for now, let's avoid ballooning our processes
with a unique shape for every object.

This added check matches CientConnection::js_console_input and makes
sure the webcontent process doesn't crash if the console is opened
while no page is available (like in a file not found situation)

Since we don't support IDL typedefs or unions yet, the responsibility
of verifying the type of the argument is temporarily moved from the
generated Wrapper to the implementation.
|
|
This is not a proper fix as we should follow the spec here but it gets
us back to a slightly more working state.
|
|
Because we declare the functions in runtime.js we need the correct
global object to be setup otherwise they cannot be accessed when
switching to the SheetGlobalObject.
|
|
Unused sockets created by EnsureConnection should not keep the socket
around (storing a strong reference will create a reference cycle).
This fixes a whole bunch more RS spins.
|
|
Just as removing individual connections can cause the vector entries to
change positions, adding or removing connections to the cache can also
move the connections around, which would make it possible for a
connection to avoid being deleted (and make the RS spin on the Notifier
for that connection).
This commit makes it so that no connection cache is left when it's
supposed to be deleted.
Fixes a few more RS spins.
|
|
If the server responds with this header, we _must_ close the connection,
as the server is allowed to ignore the socket and not respond to
anything past that response.
Fixes some RequestServer spins.

Before this commit it only allocated the global object so when it wanted
to lookup 'thisSheet' it could not find it in the global environment.
We now hotswap the global object everytime a cell evaluated.
This also fixes that SheetGlobalObject did not have an
internal_has_property meaning 'A0' could not be referenced unless it was
via a member lookup (this.A0). This was already broken before the
bindings refactoring.
The correct behavior of realms in spreadsheet is not completely clear
since what is shared between sheets is not very well defined.
The reason that just setting the SheetGlobalObject as the
global_this_value is not enough is because ECMAScript does not check the
global_this_value for members when resolving a reference in the global
environment.

When no case match we should not just execute the statements of the
default case but also of any cases below the default case.

Before this we used an ad-hoc combination of references and 'variables'
stored in a hashmap. This worked in most cases but is not spec like.
Additionally hoisting, dynamically naming functions and scope analysis
was not done properly.
This patch fixes all of that by:
- Implement BindingInitialization for destructuring assignment.
- Implementing a new ScopePusher which tracks the lexical and var
scoped declarations. This hoists functions to the top level if no
lexical declaration name overlaps. Furthermore we do checking of
redeclarations in the ScopePusher now requiring less checks all over
the place.
- Add methods for parsing the directives and statement lists instead
of having that code duplicated in multiple places. This allows
declarations to pushed to the appropriate scope more easily.
- Remove the non spec way of storing 'variables' in
DeclarativeEnvironment and make Reference follow the spec instead of
checking both the bindings and 'variables'.
- Remove all scoping related things from the Interpreter. And instead
use environments as specified by the spec. This also includes fixing
that NativeFunctions did not produce a valid FunctionEnvironment
which could cause issues with callbacks and eval. All
FunctionObjects now have a valid NewFunctionEnvironment
implementation.
- Remove execute_statements from Interpreter and instead use
ASTNode::execute everywhere this simplifies AST.cpp as you no longer
need to worry about which method to call.
- Make ScopeNodes setup their own environment. This uses four
different methods specified by the spec
{Block, Function, Eval, Global}DeclarationInstantiation with the
annexB extensions.
- Implement and use NamedEvaluation where specified.
Additionally there are fixes to things exposed by these changes to eval,
{for, for-in, for-of} loops and assignment.
Finally it also fixes some tests in test-js which where passing before
but not now that we have correct behavior :^).

Since there are only a number of statements where labels can actually be
used we now also only store labels when necessary.
Also now tracks the first continue usage of a label since this might not
be valid but that can only be determined after we have parsed the
statement.
Also ensures the correct error does not get wiped by load_state.
|
|
Also allows literal string and numbers as property names in object
binding patterns.
|
|
|
|
Since we have the to_reference method on every expression class we must
somehow communicate it did not actually return a reference.
This (ab)uses the fact that property name is only invalid with the
default constructor and already has is_valid().
|
|
This is as the spec would require you to do it and necessary for changes
to come in the following commits.

When parsing a CSS value in the context of a CSSStyleDeclaration
camelCase property setter, we don't necessarily have a Document to
provide the CSS parser for context.
So the parser can't go assuming that there's always a Document in the
ParsingContext. And ImageStyleValue can't go assuming that there's
always a Document either. This will require some more work to get things
right, I'm just patching up the null dereference for now.

This returns whether an element matches any of a set of selectors.

This small patch allows SystemMonitor's Stack tab to show the name of
the ELF object to which the displayed address refers to. This gives a
bit more of contextual information to the viewer.
A better to show this is probably a table, but I'm not that familiar yet
with the GUI framework in general, so I'm keeping things simple.

We now follow the "update a style block" algorithm from the HTML spec
instead of using the ad-hoc CSSLoader mechanism.
This necessitated improving our StyleSheet and CSSStyleSheet classes as
well, so that's baked into this commit.

This is "in a document tree" from the DOM spec.
|
|
This adds automatic scrolling when dragging items in TreeViews and other
widgets that inherit from AbstractView when the overloaded
accepts_drag() returns true. This is implemented in FileSystemModel to
allow directories and files to be dragged.

This resolves a long-standing FIXME about exposing CSS properties to
JavaScript via "camelCase" names rather than "dash-separated" names.
|
|
Note that insertRule() is really just a big TODO right now.
