- #3918
- precompute size of `StringBuilder` in `ExpressionHelper`
- reduce `string` allocations in `ViewDataEvaluator`
- also get rid of `Enumeration` state machines
- reduce the size of a few objects; use more expression-valued properties
- e.g. don't store `_modelType` in `ModelExplorer`
- add `EmptyArray<TElement>`; make empty arrays consistently `static`
- avoid `string.Split()` in HTML and tag helpers
nits:
- make `ExpressionHelperTest` tests more stringent
- correct `Message` for an `ArgumentNullException`
- remove excess `using`s in classes I touched (but often ended up leaving otherwise unchanged)
- improve doc comments
- remove `ToString()` call on a `string`
- avoid encoding `string.Empty`
- fix test file name
- remove useless variables
- correct spelling
- improve whitespace
- #5317
- previously worked only because `TagBuilder` cannot be empty and `HtmlString` overrides `ToString()`
- `TagBuilder.ToString()` (now the type's `FullName`) is also never empty
- copy `NullHtmlEncoder` from Razor and give it a better name (`PassThroughHtmlEncoder`)
- not available in this project and (from its namespace) not intended for general use
- #5028
- helpers similar to our HTML or tag helpers can use the new singleton to examine or add validation attributes
- in the most common case, helpers add validation attributes to a `TagBuilder`
- separate `DefaultValidationHtmlAttributeProvider` from `DefaultHtmlGenerator`
- avoids creating two instances of the `DefaultHtmlGenerator` singleton
- would be even uglier to require callers to cast an `IHtmlGenerator` to `ValidationHtmlAttributeProvider`
- `[Obsolete]` old `DefaultHtmlGenerator` constructor
- #5209
- update affected `HtmlHelperValiationSummaryTest` and functional tests
- add `ValidationSummaryTagHelperTest` tests to cover related scenarios
##### Behaviour changes when no errors exist for the model:
###### Tag helper
``` html
<div asp-validation-summary="ModelOnly" class="order"><h3>Oopsie<h3></div>
```
previously generated
``` html
<div class="order validation-summary-errors"><h3>Oopsie</h3><ul><li style="display:none"></li>
</ul></div>
```
and now generates
``` html
<div class="order"><h3>Oopsie</h3></div>
```
###### HTML helper
``` c#
@Html.ValidationSummary(excludePropertyErrors: true, message: "Oopsie")
```
previously generated
``` html
<div class=\"validation-summary-errors\"><span>Oopsie</span>
<ul><li style=\"display:none\"></li>
</ul></div>
```
and now generates nothing (`@HtmlString.Empty`).
This change resolves the scoped IViewComponentHelper every time its
needed, rather than misusing a shared instance. IViewComponentHelper is
stateful, so sharing an instance was the cause of this bug.
- #4690
- move `ModelBindingMessageProvider` init from `DefaultBindingMetadataProvider` to `DefaultModelMetadata`
- in addition to avoiding error cases, this removes some boilerplate
- add specific errors to `BodyModelBinderProvider`, `CompilerCache`, `CompositeViewEngine`, `ModelBinderFactory`,
and `ObjectResultExecutor`
- `DefaultRazorViewEngineFileProviderAccessor.FileProvider` now a `NullFileProvider` in empty case
* Added consistent model property/tests to ViewResult, PartialViewResult, ViewComponentResult. This resolves#4813.
* Removed unnecessary model asserts
* Removed redundant model checking
Moves IControllerArgumentBinder and IControllerPropertyActivator into
.Internal. Also renames ControllerArgumentBinder ->
DefaultControllerArgumentBinder for consistency with other controller
extensibility types.
We don't think these are 100% baked for our long term maintenance of the
product, and want to reserve the ability to make changes in the future.
This change splits up the conventional routing path from the attribute
routing path *inside* routing, instead of inside `MvcRouteHandler`. Each
attribute route group now gets its own instance of
`MvcAttributeRouteHandler` which just knows about the actions it can
reach.
This removes the concept of a route-group-token and removes the lookup
table entirely for attribute routing. This also means that the
`DefaultHandler` on `IRouteBuilder` will not be used for attribute routes,
which we are OK with for 1.0.0.
The action selector's functionality is now split into two methods. We
think this is OK for 1.0.0 because any customization of `IActionSelector`
up to now had to implement virtually the same policy as ours in order to
work with attribute routing. It should now be possible to customize the
selector in a meaningful way without interfering with attribute routing.
- #4339: remove non-recommended JSON formatter constructors
- affects `JsonInputFormatter`, `JsonOutputFormatter`, `JsonPatchInputFormatter`
- `JsonOutputFormatter` cleanup also impacts `JsonHelper`
- rename and make `SerializerSettingsProvider` class public; use it as appropriate
- #4409: make `SerializerSetings` properties get-only and `protected`
- affects `JsonInputFormatter`, `JsonOutputFormatter`
Recommended patterns:
- change `JsonSerializerSettings` values in `MvcJsonOptions` for almost all customizations
- find `JsonOutputFormatter` in `MvcOptions.OutputFormatters` when limiting per-result formatters
- start with `JsonSerializerSettingsProvider.CreateSerializerSettings()` when customizing a per-result formatter
