Steven Kirk 3b1eb338e6 Binding System refactor (#13970 ) * Update ncrunch config. * 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 #5762 Fixes #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.		2 years ago
