This change adds a base class for controllers to Mvc.Core that can be used
without a dependency on views, json, etc.
Most of the functionality on Controller moves to ControllerBase. I kept
the IActionFilter and IDisposable functionality on Controller since it's
not really a fit with the 'minimal' philosophy.
- Removes IExcludeTypeFilter
- Replaced with a property 'ValidateChildren' on ModelMetadata
- Teach ValidationVisitor to respect 'ValidateChildren' for enumerable
types.
The accessor for ElementMetadata can sometimes return null when
concurrently accessed.
This change solves this issue and simplified a bunch of lazy-computed
properties, by precomputing all type-related facets of ModelMetadata.
This also adds a ElementType property to ModelMetadata to maintain
the current separation of concerns as ModelMetadata is unaware of the
metadata provider.
- #3122 and #3123 (5 of 5)
- avoid concatenating values and wrapping them in an `HtmlString`
- switch from `string.Format()` to `AppendHtml()` in `LinkTagHelper`
- simplify `RazorPage` and `TagHelperContentExtensions` e.g. don't use a `TagHelperContentWrapperTextWriter`
- add some special cases in `UrlResolutionTagHelper`
- add `TagBuilder` and `StringHtmlContent` special cases to avoid `StringWriter` use when value is an `HtmlString`
- move `HtmlTextWriter` optimizations a bit lower and add missing checks for that type
nits:
- correct comments that incorrectly mention `HtmlString`s
- update comments in `JavaScriptStringArrayEncoder`
- part of #3123 (4 of 5)
- `LocalizedHtmlString` should not subclass `HtmlString`; now implements `IHtmlContent`
nits:
- clean up a few doc comments
- remove duplicate tests reported while testing these fixes in VS
This change removes the IActionContextAccessor as a dependency of
UrlHelper, and shifts UrlHelper to use a factory pattern. Consumers of
IUrlHelper should create an instance using the factory when needed.
This is the last part of MVC that has a dependency on IActionContext
accessor. As part of this change we no longer register it by default, and
treat it as an optional component.
This change removes the dependency of TempData on the IHttpContextAccessor
by creating an ITempDataDictionaryFactory abstraction. In general, no one
will replace the factory, it's just indirection.
This allows us to drop our dependency on IHttpContextAccessor, and move it
to the functional tests where we specifically depend on it.
The bulk of code churn here is to update tests that use TempData.
This change resolves#3512 and #3636 by removing 'magic' link generation
and adding an extension method to add routes to areas correctly using the new
pattern. This is pretty much exactly the same as how MapWebApiRoute works.
For site authors, we recommend adding area-specific routes in a way that
includes a default AND constraint for the area. Put your most specific
(for link generation) routes FIRST.
Ex:
routes.MapRoute(
"Admin/{controller}/{action}/{id?}",
defaults: new { area = "Admin" },
constraints: new { area = "Admin" });
The bulk of the changes here are to tests that unwittingly relied on the
old behavior.
- Prior to this change we were using `Linq` throughout our `TagHelper`s which resulted excess allocations.
- Also went through our data structures and changed some from `Enumerable<T>` to `IList<T>` where we were just not exposing the more accessible types (list).
- Changed several locations of `foreach` to `for` to remove the enumerator allocation.
#3599
This change simplifies IFormatFilter's API and removes the dependency on
IActionContext accessor.
The old API for IFormatFilter required computing state based on the
current request as part of the constructor, which in turn implied the use
of a context accessor. This isn't really needed. I didn't preserve caching of
the 'format' as that seems like an early optimization.
This is a companion change to make the RouteValueDictionary type more
promient. Using the concrete type here allows to avoid allocations in a
lot of common scenarios.
- #3123 (3 of 5 or so)
- react to rest of aspnet/Antiforgery@6a9b38d
- remove `HtmlEncoder` from localization requirements
- literal `hidden` is no longer HTML encoded (was a no-op anyhow)
- #3571 and part of #3123
- split `ContentViewComponentResult` in two
- add `HtmlEncoder` to `ViewComponentContext`
- remove use of `WebUtility.HtmlEncode()` and `HtmlDecode()`
nits: remove unused `using`s in files I had open
- #3428
- the `public` setter was not useful when this class is used as an attribute
- make property `virtual` to support other override patterns
- update existing test to use both override patterns
This change introduces ControllerContext for inside of Controllers, and
controller-specific extensibility points. ControllerContext carries with
it the model binding infrastructure needed to do all of the things that
controllers need to do.
- Removed `WriteTagHelperAsync` methods from `RazorPage`.
- Moved `WriteTagHelperAsync` tests into Razor since `TagHelperOutput` is now an `IHtmlContent`.
- Updated code generation test files.
aspnet/Razor#358
- `true` has the opposite meaning now but most changes are due to new parameters names in `IViewEngine`
- use name names in `Microsoft.AspNet.Mvc.ViewFound` and not found events
- remove `IRazorPage.IsPartial` and `RazorView.IsPartial`
- remove `IsPartial` properties from `Microsoft.AspNet.Mvc.Razor.BeginInstrumentationContext` and end events
- add parameter checks to `RazorView` constructor; instances are not retrieved from DI
nits:
- remove unused `cacheKey` parameter from `RazorViewEngine.CreateCacheResult()`
- correct duplicate test names in `RazorPageTest`
- also `...OnPageExecutionListenerContext` -> `...OnPageExecutionContext`
- `IRazorViewEngine.MakePathAbsolute()` -> `GetAbsolutePath()`
- set `IsPartial` on all `IRazorPage` instances
- improve consistency of methods in `HtmlHelperPartialExtensions`
- a couple unnecessarily passed `htmlHelper.ViewData`
- add missing tests of these extension methods
- restore parameter checks in `CompositeViewEngine`
- reduce `List<string>` and remove enumerator allocations in `CompositeViewEngine`
nits:
- correct a few comments
- use `<seealso/>`
- do not blindly use `FindPage()` / `FindView()` result in `Exception.Message` or returned results
- failure scenarios involve new `Any()` calls but rarely additional `List<string>()` allocations
- change `ViewEngine_ViewNotFound` resource to be consistent with similar errors
- remove trailing period at end of searched locations list
nit: remove remaining `null` checks of `SearchedLocations` in not found cases; never `null` then
- #3307
- relative paths are now supported in `View()` calls from components and view components,
`Html.PartialAsync()` and similar calls, and `RazorPage.Layout` settings.
- support absolute paths, relative paths, and view location lookups consistently / everywhere
- support view paths in `TemplateRenderer` e.g. passing an absolute path to `Html.EditorFor()`
- take a big swing at the `IRazorViewEngine` and `IViewEngine` interfaces
- split lookups (view names) from navigation (view paths)
- remove `Partial` separation; use parameters to set `IsPartial` properties
- correct `ViewContext` copy constructor and add unit test
- extend unit tests to cover relative paths
- fix existing tests to handle newly-required extension in an absolute path
- add functional test that chains relative paths
nits:
- remove some YOLO line wrapping
- `""` -> `string.Empty`
This textwriter needs to inherit HtmlTextWriter and the
StringCollectionTextWriter needs to have the right conditional test.
This allows us to 'pass-through' any IHtmlContent instances without
writing out intermediate strings.
- Prior to this change the `<meta ...>` generated had a name attribute. As an alternative we're using the `content` attribute in conjunction with the `name` attribute to ensure compliance.
#3449
- wrong fix especially now that test encoders work as expected
- touch up `HtmlHelperTest` and `RazorViewTest` since test encoders are now consistent
- remove references to old `Microsoft.Extensions.WebEncoders.Testing` package
This reverts commit a9d5876cd9.
- but leave `FormTagHelperTest` and `ValidationMessageTagHelperTest` cleanup alone
nit: use `string.Empty` in `HtmlHelperLinkGenerationTest`
- #3140
- clone `MediaTypeHeaderValue` instance before updating it when content negotiation succeeds
- avoids changes to `MediaTypeConstants` properties and `OutputFormatter.SupportedMediaTypes` entries
- `MediaTypeHeaderValue.Clone()` does not exist in our DNX Core fork of this class
- in previous implementation, was called defensively rather than when required
- update `WebApiCompatShimBasicTest` functional tests to use `MvcTestFixture<TStartup>` everywhere
- #3140 blocked that final migration
- remove `TestHelper` since it's no longer referenced
nits:
- remove comments mentioning `TestHelper`
- correct spelling of "negotiation"
- Replaced Type.GetCustomAttribute<T> with Type.IsDefined where the
attribute instance is only used to check if it's defined, to increase
performance.
Resolves#3416
- Added functional tests to validate data created from a `SelectTagHelper` does not impact following `<select>` tags.
- Also moved the new `SelectTagHelper` communication flow into `TagHelper.Init`.
#3347
- #3227
- much of change is to tests, creating and passing `ModelMetadata`
- updated `InputFormatterContext` to make `ModelMetadata` available to `JsonInputFormatter`
- walk `ModelMetadata` tree to get information about property with an issue
- add missing `null` checks in `ModelStateDictionaryExtensions`
- Changed all `GetChildContentAsync` calls to come from `TagHelperOutput` instead of `TagHelperContext`.
- Updated `ReaderAtEndOfFormTagHelper` to properly detect changes inside of a `Form`s body by calling the `Init` method.
- Add test to `RenderAtEndOfFormTagHelperTest`.
aspnet/Razor#571
The missing piece here is is that StringOutputFormatter needs to set the
ContentType so that it gets overridden. The problem is that the formatter
is likely called with something like application/json, but decides to
write a string anyway. So because we're saying 'yes we can write' we also
need to override what we're writing.
