- Make ViewExecutor a service
- Add facades for ViewResult/PartialViewResult
- Add eventing for ViewFound/NotFound in PartialViewResult
- Add eventing around view execution
- Cleanup of some various eventing & our tests code
This change fixes call sites on the main request path for a simple site
(model binding, validation, views) that allocate boxed list enumerators.
Some cases aren't addressed by this change because the fix is too invasive
or requires changing an important contract to take IList instead of
IEnumerable. Will follow up on those case by case in order of importance.
- #2969
- add `ModelBindingMessages` for configuration and `IBindingMetadataProvider` overrides
- use `interface` to avoid `new` oddities when adding a setter to an `abstract` property
- add `IModelBindingMessages` to `ModelMetadata` for use in rest of the product code
- plumb the various bits through the system
- add integration tests using a custom `IBindingMetadataProvider`s to override messages
nits:
- remove unused resources
- use `AttemptedValue` and not `model` in `SimpleTypeModelBinder`
This change works around two mono issues that are blocking travis. I'd
like to have tests skip instead, but unfortunately that would mean not
running any validation tests on mono so this seems better.
- RuntimeHelpers.GetHashCode will sometimes crash the runtime
- PropertyHelper sometimes returns throws null-ref
- Added generic add model error and remove extensions for
ModelStateDictionary, to avoid using hard coded strings then specifying
model state dictionary keys.
- Added generic removal all extension for ModelStateDictionary, to
support removing all the model state keys for given expression.

This solves a perf issue for views which produce content that is smaller
than the buffer size of HttpResponseStreamWriter. In this case, the writer
ends up synchronously writing to the Response as part of Dispose which
affects perf.
This change makes ViewComponentResult respect an existing Content-Type
setting on the HttpResponse. Code is very similar to the code in
ViewExector, and includes the same quirks.
Abstractions - Core MVC extensibility
Controllers - MVC implementations of .Abstractions and supporting
contracts
Infrastructure - General purpose support APIs. Metadata APIs that don't
fit clearly with a feature or with .Abstraction
[FromServices] requires modelbinding to run for each of these four
properties, which allocates a lot, and ultimately just ends up calling
GetRequiredService in the end.
Also, retrieving these services is now lazy, which should be very
beneficial as few of them aren't used often.
We don't want these extensions methods defined in a wierd namespace, it's
straightforward and future-proof to just make these strongly-typed
collections.
- #2722
- make communication of errors from formatters to `BodyModelBinder` explicit
- `JsonInputFormatter` now adds errors to `ModelStateDictionary` with correct key
- change `InputFormatter.SelectCharacterEncoding()` to add an error and return `null` when it fails
- one less `Exception` case and removes some duplicate code
nits:
- improve some doc comments (more `<inheritdoc/>`, `<paramref/>` and `<see/>`)
- add another two `BodyValidationIntegrationTests` tests
Improves authoring experience when using TagBuilder by taking advantage of
IHtmlContentBuilder an its extension methods.
TagBuilder.InnerHtml is no longer settable.
Adds a new property, FieldName, to ModelBindingContext. The FieldName is
the name of whatever code-element is being bound, regardless of what
model-prefix is in use.
This is needed for cases like the Header model binder. We always want to
use the property/parameter name and we don't care about model prefixes.
We allocate a separate list for model-binding related objects when we
create the resource filter contexts, and these lists then live the
lifetime of the request. These *may* be modified by user code in
filters as a supported feature, but rarely are changed in practice.
This change adds a simple CopyOnWriteList implementation to reduce the
amount of copying that's actually done.
- The corresponding Razor change results in `HelperResult`s being rendered with async lambdas.
- This change enables `TagHelper`s and other async code to exist inside of `HelperResult` blocks.
- Added test to validate Templates (they generate `HelperResult`s) can utilize `TagHelper`s correctly.
- Rename `RazorPage`s `RenderBodyDelegate` to `RenderBodyDelegateAsync`.
aspnet/Razor#494
- #2993
- use `ClosedGenericMatcher` to handle e.g. non-generic model types implementing requested interfaces
- reduce `IsAssignableFrom()` use since created binders use explicit casts i.e. handle explicit implementations
- also add more integration tests covering various collection key formats, some with validation errors
- merge a few `[Fact]`s into `[Theory]`s
The copy constructor is chaining to the wrong constructor. This results in
an extra 8 allocations of ModelStateDictionary per-request. All of the
various filter contexts inherit from ActionContext, that's how you get the
8 extras.
Small problem but easy fix.
- #2992
- use new properties to replace common helper methods
- still a few `Nullable.GetUnderlyingType()` calls
- creating `ModelMetadata` or sites lacking `ModelMetadata` access e.g. `ModelBindingHelper.ConvertTo()`
- #2905
- override `Order` implementation inherited from `TagHelper`
- only exception is `UrlResolutionTagHelper` which already overrides `Order` to execute much earlier
- #2941
- honor `ModelBindingResult.IsModelSet` and use `ModelBindingResult.ValidationNode`
- enable correct validation of collections or after model binding falls back to the empty prefix
- code previously matched `Controller.TryValidateModel()`; less context available in that case
- `ScriptTagHelper`, `LinkTagHelper` and `ImageTagHelper` now default to using `output.Attributes["href|src"]` if it's present when they run. This enables other `TagHelper`s to run prior and add those attributes.
- Added unit tests to validate this behavior.
- Updated `ImageTagHelper` functional test resources. Now that we're always defaulting to `output.Attributes["src"]` for `ImageTagHelper.Src` we're properly copying attributes back into the `output.Attributes` collection in the correct order (isntead of appending to the end).
#2902
- Updated implementation to do a best guess at copying an attribute back into `TagHelperOutput.Attributes`.
- Updated existing functional and unit tests to account for maintained attribute order.
- Added a set of complex order based unit tests to validate `CopyHtmlAttribute` properly maintains order.
#2639
- Use compilation options from the Compilation itself
- Get the parse options from the first syntax tree
- Get the build time IAssemblyLoadContext directly
- #2836
Part 1: Use existing property values when recursing in `MutableObjectModelBinder`
- remove `ComplexModelDTO` because that indirection made fixing this issue more difficult and doesn't add value
- started with an old closed PR (#2241) which did some of this work
- correct `MutableObjectModelBinderTest` tests that exercised behaviour that can't occur
- the old `dto.Results` dictionary was never incomplete; nor could it contain `null` values
Part 2: Change `MutableObjectModelBinder` to pass complex property values into binding system
- model binding no longer trounces nodes in the model tree that aren't bound
- create model instances less often in `TryUpdateModel` scenarios
- refactor `EnsureModel()` to `GetModel()` and use appropriately
- reorder logic in `SetProperty()` and `AddToProperty()` to avoid copying to / from the same collection
- also cleans up some code duplication
nits:
- clean up `MutableObjectModelBinderTest`
- fix odd line wrappings and indentation
- use `nameof()` more
- use `string.Empty` more
- simplify a couple of `Returns()` expressions
- make assertions in `TryUpdateModelIntegrationTest` more readable
- no need to work through `ModelStateDictionary.Keys`
- also use `Length` instead of `Count()`; test code but we don't need Linq at all in that test class
some more tests.
This change reverts the behavior change from
a6ce9abab1 and adds more tests around the
scneario that was actually broken.
The right behavior is that unconvertable values result in a validation
error. There's no special behavior around value types and required values.
- Now allow the attribute to exist on `img` and `source` tags.
- Updated existing `UrlResolutionTagHelper` functional test to validate `srcset` attribute.
#2964
- Making TagRenderMode a property in TagBuilder.
- Modifying places where TagBuilder is used to suit the new model.
- This reduces space occupied by a normal application by 11.8%.
This change restores a link generation behavior from MVC5 and earlier
where 'action' and 'controller' values are special cased-when using
Url.Action(...).
The change is that in-effect 'action' and 'controller' are always included
in the route values given to the routing system. Passing a null value into
the Url.Action(...) method means that the ambient value for that token
should be used explicitly. This means that the 'action' and 'controller'
tokens become sticky, even when something to the lexical left in the URL
(like area) changes.
- Razor rendering now understands `TagMode` which allows void elements to be rendered.
- Added a `TagStructure.WithoutEnd` bit to `InputTagHelper`, `ImageTagHelper` and `UrlResolutionTagHelper`. This will allow users to write the various elements in the void format. Used the HTML5 spec to determine the elements appropriate.
- Added tests to ensure `TagMode.StartTagOnly` is rendered properly.
- Updated a few functional tests to showcase the void element formats.
aspnet/Razor#450
ActionBindingContext
This change replaces IScopedInstance<T> in favor or IActionContextAccessor
and IActionBindingContextAccessor. In the spirit of IHttpContextAccessor,
these are both singletons which use AsyncLocal for storage.
This change allows the invoker factory to be cached which results in some
significant perf gains.
