- #1999
- may have reordered the precedence comments as I double-checked the implementations
- `CheckBox()` and `RadioButton()` were examples of such updates
nits:
- use SSL in documentation links
- simplify mentions of format strings
- remove a few phrases that didn't say much and duplicated `<remarks>`
- #3918
- don't repeat allocations for identical calls; helps w/ e.g. label / input / validation clusters
- add `NameAndIdProvider`; it stores `PreviousNameAndId` in `HttpContext.Items`
- `PreviousNameAndId` allocated only when `string`s are allocated e.g. "id"s were sanitized
- #3918
- lazy-load `TagBuilder.InnerHtml`; add `HasInnerHtml` property for conservative use
- depends on aspnet/HtmlAbstractions@0781b5a (adds `HtmlContentBuilder.Count`)
- don't use a `HtmlContentBuilder` at all in `DefaultHtmlGenerator.GenerateValidationSummary()`
- avoid instantiating `HtmlContentBuilder` when short-circuits make it unnecessary
- provide correct `HtmlContentBuilder` capacity where known
- #5347
- inconsistent bounds checking caused problems after `ArrayPool<char>` fell back to `new char[2048]`
- would fail a `Debug` assertion in Debug builds and loop endlessly in Release builds
- change to `CacheTagHelper+CharBufferHtmlContent` is for correctness only
- always uses a `CharArrayBufferSource` and that returns arrays of the exact size requested
- #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
- #4116
- generalize rules for `ModelMetadata` creation; minimize metadata changes when Model is updated
- down to a single special case in VDD for `Nullable<T>`
- note existing functional tests did not need to change
- remove `ViewDataDictionary(ViewDataDictionary, object)` constructor; use `new VDD<object>(source, model)`
- allow all `Model` assignments in a view component
- copy-constructed VDD in `ViewComponentContext` previously preserved the source's declared type
nits:
- do not call `virtual SetModel()` method from constructor; now mostly redundant
- logic in copy constructor and `SetModel()` is consistent but different enough to keep code separate
- add some missing doc comments
- fix doc comment property versus type confusion; never need to specify `ViewDataDictionary.` prefix
- fix a few `TemplateBuilder` comments and remove unnecessary `model: null` argument to VDD constructor
Believe it or not, this one in ActionResult is showing in TechEmpower. I
did a pass on all of the product code since the cache task actually
improves the readability of the code 😎
- remove duplicate `null` checks in `ViewDataDictionary` constructors
- correct a couple of code comments
- use a `public` constructor for `ViewDataDictionary` in `ViewExecutor`
* Added ViewComponentFeture and ViewComponentFeatureProvider to perform view component discovery.
* Changed view component discovery to use application parts.
* Changed ViewComponentDescriptorProvider to make use of Application parts.
* Added AddViewComponentsAsServices method on IMvcBuilder that performs view component
discovery through the ApplicationPartManager and registers those view components as
services in the service collection. Assemblies should be added to the ApplicationPartManager
in order to discover view components in them in them.
Just a safety measure in case anything evades our 'flattening'. I don't
have any evidence that we're failing to clear something, but we want this
here as a safeguard.
- Simplify things that used to rely on HtmlTextWriter. This behavior is
now the default.
- Simplify a whole mess of Razor TextWriter code.
- Integration test for merging of TagHelper buffers back into the 'main'
buffer.
- #3482
- see new tests; many failed without fixes in the product code
- add support for binding `IFormFileCollection` properties
- make `FormFileModelBinder` / `HeaderModelBinder` collection handling consistent w/ `GenericModelBinder`++
- see also dupe bug #4129 which describes some of the prior inconsistencies
- add checks around creating collections and leaving non-top-level collections `null` (not empty)
- move smarts down to `ModelBindingHelper.GetCompatibleCollection<T>()` (was `ConvertValuesToCollectionType<T>()`)
- add `ModelBindingHelper.CanGetCompatibleCollection()`
- add fallback for cases like `public IEnumerable<T> Property { get; set; } = new T[0];`
- #4193
- allow `Exception`s while activating collections to propagate
- part of #4181
- `CollectionModelBinder` no longer creates an instance to check if it can create an instance
- not a complete fix since it still creates unnecessary intermediate lists
nits:
- correct a few existing test names since nothing is not the same as `ModelBindingResult.Failed()`
- remove a couple of unnecessary `return` statements
- correct stale "optimized" comments
- explicit `(string)`
- aspnet/Coherence-Signed#187
- remove `<RootNamespace>` settings but maintain other unique aspects e.g. `<DnxInvisibleContent ... />`
- in a few cases, standardize on VS version `14.0` and not something more specific
- standardize on the `Type` extension method; less verbiage
- `ModelMetadata` had a redundant `IsAssignableFrom()` call
- `ModelBindingHelper.ValidateBindingContext()` over-engineered and used just once
- do useful bit inline in `KeyValuePairModelBinder` but now a silent "does not apply" case
- This bit was missed when changing the `ViewComponent` invocation pattern resulting in the inability to invoke `ViewComponent`s with arguments in a `Controller`.
#4004
- #2969
- `RemoteAttribute` did not support `IStringLocalizer` overrides
- use same `MvcDataAnnotationsLocalizationOptions` property as for other `ValidationAttribute`s
- error message `NumericClientModelValidator` added could not be overridden
- not related to `IStringLocalizer` because users have no way to set the resource lookup key
- extend `IModelBindingMessageProvider` to add the necessary `Func<,>`
- also correct problem using resources with `RemoteAttribute` and add lots of tests
This change removes a layer of abstraction. These validators now just do
what they do now without creating a bunch of intermediate objects.
ModelClientValidationRule has been removed, and client validations
manipulate the attributes collection of a tag directly.
* Moved instantiation of view components into DefaultViewComponentActivator
* Introduced IViewComponentFactory to handling setup of new view component instances.
* Added a release method on IViewComponentActivator for handling tear down of view
component instances.
These changes are aimed at significantly improving the performance of
MVC/Razor when a large amount of content is in play or a large number of
TagHelpers are used.
A few issues addressed:
- Buffer sync writes after a flush has occurred so that we can write them
asyncronously. The issue is that an IHtmlContent can only do sync
writes. This is very bad for Kestrel in general. Doing these writes
async is better for our overall perf, and the buffer that we use for it
is from the pool.
- 'Flatten' ViewBuffers when possible. A page with lots of TagHelpers can
end up renting a ViewBuffer and only write 2-3 things into it. When a
ViewBuffer sees another ViewBuffer we can either steal its pages, or
copy data out and 'return' its pages. This lets us use 3-4 buffers for a
large Razor page instead of hundreds.
