* Update ncrunch config.
* Tidy up reflection and multi-binding APIs:
- Move `BindingBase` and `MultiBinding` into Avalonia.Base
- `BindingBase` becomes a true base class for all bindings, and contains only the `Instance` method
- Properties common between reflection and compiled bindings are moved into `StandardBindingBase`
- `Binding` is moved to Avalonia.Base and renamed to `ReflectionBinding`
- A compatibility shim for `Binding` remains in Avalonia.Markup
- Remove `IBinding` and `IBinding2`
- Remove `ITreeDataTemplate's usage of `InstancedBinding`
- Remove `NativeMenuBarPresenter`s usage of `InstancedBinding`
- Remove `InstancedBinding` as it is now unused
This required an update to the DataGrid submodule: cell data validation has been temporarily removed as this used `InstancedBinding`.
* `Instance()` => `CreateInstance()`.
The use of "Instance" as a verb is quite unusual apparently ;)
* Seal classes where appropriate.
* Seal classes where appropriate.
* Remove `StandardBindingBase`.
Simply duplicate the members in reflection and compiled binding classes.
* Delete deleted submodule directory.
* Add missing attribute.
Fixes compile error.
* Fix reference to removed class.
* Update suppressions.
* Improve FontCollection user story
* Make adjustments after review
* Refactor IsFontFile
* Make FontFamilyLoader internal
Make tests happy again
* Update baseline
* Adjust modifier

* WIP: Benchmarks
* Initial refactor of binding infrastructure.
- `ExpressionObserver` has been removed and its functionality merged with `BindingExpression`
- `BindingExpression` handles all types of `BindingMode` itself; doesn't require `BindingOperations.Apply` to set up a separate observable for `TwoWay/`OneWayToSource` bindings
- This allows us to fix some long-standing issues with `OneWayToSource` bindings
- Expression nodes have been refactored
- No longer split between `Avalonia.Base` and `Avalonia.Markup`
- Categorize them according to whether they use reflection or not
A few tests are failing around binding warnings: this is because the next step here is to fix binding warnings.
* Make default binding Source = UnsetProperty.
Null is a theoretically valid value for `Source`; setting it to null shouldn't mean "use the data context".
* Move logging to BindingExpression.
As `BindingExpression` now has enough information to decide when it's appropriate to log an error/warning or not.
Fixes#5762Fixes#9422
* Add compatibility hack for older compiled bindings.
Previously, `CompiledBindingPathBuilder` didn't have a `TemplatedParent` method and instead the XAML compiler rewrite templated parent bindings to be a `$self.TemplateParent` property binding. resulting in extraneous logs.
Add a constructor with an `apiVersion` to `CompiledBindingPathBuilder` which will be used by newer versions of the XAML compiler, and if a usage is detected using an `apiVersion` of 0, then upgrade `$self.TemplatedParent` to use a `TemplatedParentPathElement`.
* Log errors from property accessors.
* Don't log errors for named control bindings...
...on elements which aren't yet rooted.
* Log errors for failed conversions.
* Use consistent wording for binding warnings.
"Could not convert" instead of "Cannot convert".
* Log warnings for converter exceptions.
* Don't convert new TargetTypeConverters each time.
* Added failing test for implicit conversion.
* Support cast operators in compiled bindings.
A bit of a hack as we'd ideally not be using reflection when using compiled bindings.
* This shouldn't be a public API.
Should only be used for tests.
* Make enum/int conversion work.
* Check for SetValue equality after conversion.
And also use "identity equals" where value types and strings use `object.Equals` and reference types use `object.ReferenceEquals`.
* Added ConverterCulture back to bindings.
* Fix merge error.
Removed deleted files from csproj that were re-added due to indentation changes.
* Use BindingExpression directly in ValueStoe.
* Introduce BindingExpressionBase.
And `UntypedBindingExpressionBase`.
* Make TemplateBinding a BindingExpression.
* Make DynamicResource use a BindingExpression.
* WIP: Start exposing a BindingExpression API.
* Finish exposing a BindingExpression API.
* Fix OneTimeBinding.
* Remove unneeded classes/methods.
* Don't call obsolete API.
* Make BindingExpressionBase the public API.
This matches WPF's API.
* Added BindingExpressionBase.UpdateTarget.
* Initial implementation of UpdateSourceTrigger.
* Don't use weak references for values.
If they're boxed values, they can get collected.
* No need for virtual/generic methods here now.
* Reintroduce support for binding anchors.
Turns out these were needed by animations, just our animation system has no unit tests so I missed that fact earlier. Add a basic animation unit test that fails without anchor support, and add binding anchors back in. Currently a private API as I suspect this feature shouldn't be needed outside the framework.
* Include new property in clone.
And add real-life example of `UpdateSourceTrigger=LostFocus` to BindingDemo.
* Fix merge error.
* Updated BindingExpression tests.
- Make them run for both compiled and reflection bindings (found a bunch of tests that fail with compiled bindings)
- Make them not depend on converting the `BindingExpression` to an observable and instead test the end result of the binding on an `AvaloniaObject`
* Fix compiled binding indexer tests.
* Use data validation plugins in PropertyAccessorNode.
Added a warning suppression for now: we may need a separate `DataValidators` list for AOT-friendly plugins.
* Don't separate plugins by reflection.
`DataAnnotationsValidationPlugin` is public and so it can't be moved. No point in moving the others if this one will be in the wrong place.
* Remove unneeded methods.
* Make reflection binding tests use a string.
Convert the `System.Linq.Expression` to a string and then use this, as reflection bindings will always be instanced with a string path.
* Added TODO12 plan for IBinding2.
* Use more specific exception.
* Fix nits from code review.
* Make expression nodes sealed where possible.
* Unsubscribe on Stop, don't re-subscribe.
D'oh.
* Tweak ExpressionNode lists.
Saves a few K in benchmarks and it's a cleaner API.
* Add a pooled option in BindingExpressionGrammar.
Micro-optimization.
* Avoid allocations when enumerating binding plugins.
* Add IBinding2 support to observable bind overloads.
In the case of `TemplateBinding`, the `IObservable<object?>` bind overload is selected by C#. Add an explicit check for an `IBinding2` here to use the more performant code-path.
* Remove disposed binding from ImmediateBindingFrame.
* Added TemplateBinding benchmarks.
* Remove duplicate items.
Seems to have been caused by a merge error.
* Fix exception when closing color picker.
And add tests.
* Don't skip converter when binding to self.
* Don't pass UnsetValue to converters.
This follows WPF behavior.
* Log element name if present.
More useful than just logging the control hash code.
* Respect binding priority.
* Throw on mismatched binding priorities.
We don't want to respect the binding priority in this case as it breaks `TemplateBindings` when the default `LocalValue` priority is passed. Instead make sure that the priority parameter matches that of the expression.
This reverts commit a72765d705.
* Convert to target type in TemplateBinding.
* Short-circuit target type conversion for same types.
- animation/layout/render cycle is now managed from a central location
- animations are now throttled if animation/layout/render pass takes longer than a frame which previously caused a soft-freeze with input not being processed
- the public API is trimmed to make sure that we can make other planned changes during the 11.x support cycle
"Changelog":
- IClock is hidden and is planned to be replaced later
- Animator classes are hidden and are planned to be refactored later
- IAnimation members are hidden, it's supposed to be a marker interface for Style.Animations collection now, to start animations manually use Animation.RunAsync
- Sealed several classes in Avalonia.Animation namespace
- Spring class is removed from the public API (it wasn't possible to use it directly in a meaningful way anyway)
- Sealed brushes, transforms, effects and drawings
- Removed separate dispatcher priorities for Layout and Composition, everything now happens from a central place with Render priority (same as WPF)
- - some private "hook" priorities are added for now, those will be removed later
- IRenderLoop is hidden and removed from locator
- IRenderer is hidden (the plan is to remove that concept later)
- - Renderer.Start/Stop exposed as StartRendering/StopRendering on the toplevel (will be on a CompositionTarget/PresentationSource-like type later)
- - Renderer.Diagnistics exposed as RendererDiagnostics (same)
- - Renderer is no longer created by the platform code and is created by TopLevel itself
- - From the user-code hit-testing should be done by VisualExtensions.GetVisual(s)At, which has the same features
- - For unit tests a separate IHitTester interface is added which can be changed for a particular toplevel
- ILayoutManager is hidden
- - LayoutManager.ExecuteLayoutPass() exposed as TopLevel.UpdateLayout()
- Custom animators now have a separate base class that only deals with interpolation
Minor improvements:
- Compositor has a mode that doesn't use DispatcherTimers, useful for unit tests
- Introduced ScopedTestBase that auto-resets the locator when test is finished
`ItemsControl` now works more like WPF, in that there are separate `Items` and `ItemsSource` properties. For backwards compatibility `Items` can still be set, though the setter is deprecated. `Items` needed to be changed from `IEnumerable` to `IList` though.
A lot still broken, in particular virtualization is completely removed.`ItemsPresenter` now no longer has an `Items` or `ItemTemplate` property; it detects when it's hosted in an `ItemsControl`. `IItemsPresenter` interface removed.
- Removes the `IStyler` service and the `Styler` implementation
- Moves the logic for applying styles and control themes into `StyledElement`
- Removes the style `TryAttach` method from the public API
- Removes style caching for now - this will need to be added back
