When an action contained an attribute derived from HttpMethodAttribute,
doesn't specify an attribute route and there is also another attribute
extending HttpMethodAttribute that has a route defined on it; we ignored
the HttpMethodAttribute attribute without a defined route when building
the set of action selectors for the method.
This caused the resulting action to be unbounded and to accept requests
for other verbs not associated with it. The root cause of the problem was
that attributes override equality and do a field by field comparison but
ignore fields in the base classes of the type, so if an attribute is part
of a class hierarchy (like Http*Attributes) there might be two different
attributes that get considered equal.
The fix for the problem has been to change using Contains on a couple of
collections (that uses the equals method on the underlying object) and
check for the existence of the attribute on the collection directly by
using reference equality.
This test uses the new features in the service provider to verify that we
don't reference any scoped services from singletons.
Note that this can't really cover the cases where we have optional
services or where we replace default services (like DI for controllers).
You'll just have to be careful.

- #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
'ValidationExcludeFilter' -> 'SuppressChildValidationMetadataProvider'
Also moved to .ModelBinding for improved discoverability. There aren't
many reasons user code would have a using for .Validation.
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.
- #3595 sub-items 2 through 4
- handle an indexer name in `ValidationResult.MemberNames`
- aligns `ModelNames.CreatePropertyModelName()` with `TemplateInfo.GetFullHtmlFieldName()`
- handle multiple elements in `ValidationResult.MemberNames`
- later elements previously ignored
- set `ValidationContext.MemberName` to `null` when no property name is available
- using type name for a member name was just wrong
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.
This change to ModelBinderFactory makes the caching much more aggressive,
by caching all non-root binders. There's some trickiness here around
making sure we have the right behavior when all providers return null. See
the tests and comments.
I also kept the change I made for a temporary workaround to use a
dictionary rather than a "stack" for cycle breaking. This seems like an
overall improvement in clarity.
- `AdditionalCompilationReferences` is a purely additive option to add `MetadataReference` instances to be used for Razor compilation.
- Added a test to validate the compilation references get combined with the `ApplicationPartManager`s metadata references.
#4497
- #4652
- previously ignored for top-level models
- `ModelBinderProviderContext.BindingInfo` is now never `null`
- similarly, use type metadata (as well as parameter info) for `ModelBindingContext.BinderModelName`
- previously ignored when overridden in `ControllerArgumentBinder`
- Updated `ScriptTagHelper` and `LinkTagHelper` to maintain their quotes on generated script tags.
- Removed `TagHelperOutputExtensions`. It's no longer needed.
- We no longer string replace quotes directly. We rely on encoding and the initial representation of an attribute to ensure quotes don't break generated attributes.
- Updated tests.
This workaround an issue \ bug with the results returned by DependencyContext where
the path uses a mix of forward and back slashes which causes comparison with Assembly.Location that only
uses forward slashes to fail.
This test was relying on the parsing behavior of QueryString, that it
would omit the key and value when the value is empty. The expectations
weren't consistent with other tests for 'empty' values.
This change simplifies a bunch of code and fits more in line with the
current design of model binding.
Now, a model binder only has to do anything if it was successful.
'return' is enough to indicate failure.
This will help future generations maintain this class. Notice that the
protected methods that are going away all just call into another
extensibility point (other than the executor). If we need to we could make
that extensible in the future and then we have the same support with fewer
hooks and less complexity.
This change just rearranges some code in the argument binder with a mind
towards performance and clarity. We're removing a few Task<T>'s here as
well in certain cases, but not yet all of them. We additionally save a
dictionary in the case where you have bound properties.
Hopefully these changes break the code into more discrete and sensible
units without multiple levels of indirection without abstraction.
- Main 'driver' code
- BindModel
- ActivateProperty
We want this change to avoid MVC eagerly reading the form. This is good
for general perf and also for scenarios where you want read the body
yourself (large file uploads).
We DO have scenarios where you want to configure the value providers
per-request or also to change the limits on the value providers (form) so
it's worth keeping these around on the context.
- relates to #4445
- also relates to #4309 / fb07fee though restored and renamed files are slightly different
- latest Unobtrusive version; copy just one file under `wwwroot`
- add JavaScript file and CDN links to enable manual testing of `[Remote]` tests in `BasicWebSite`
- include renamed files for recreating the minimized JavaScript file manually
- intent was to make HTML helper output close to the tag helper output but source got over-complicated
- the output files for `Order.cshtml` and `OrderUsingHtmlHelpers.cshtml` now differ only in attribute order
- i.e. HTML helpers output attribute alphabetically while tag helpers output them in order added
- #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
I recently consolidated some code in routing that made the behavior for
attribute routes and conventional routes more consistent. So now, a
catch-all will add a null value to the RVD if it doesn't capture any text,
but will NOT trounce an existing value in the RVD.
This test depended on the behavior where attribute routes didn't ever add
a null value for a catch-all. The fix is to just add a default to the
catch-all.
- #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
* Added TagHelperFeature and TagHelperFeatureProvider to perform tag helper discovery.
* Changed tag helper discovery to use application parts when using tag helpers as services.
* Added FeatureTagHelperTypeResolver to resolve tag helper type definitions from the list of application parts.
* Added AddTagHelpersAsServices extension method on IMvcBuilder and IMvcCoreBuilder that
performs tag helper discovery through the ApplicationPartManager and registers those tag helpers as
services in the service collection. Assemblies should be added to the ApplicationPartManager
in order to discover tag helpers in them in them. The @addTagHelper directive is still required on
Razor pages to indicate what tag helpers to use.
* Remove IAssemblyProvider.
* Remove DefaultAssemblyProvider in favor of DefaultAssemblyPartDiscoveryProvider.
* Update AddMvcDnx to add the list of DNX discovered assemblies to the list of application parts.
* 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.
* Added ControllerFeature and ControllerFeatureProvider to perform controller discovery.
* Changed controller discovery to use application parts.
* Changed ControllerActionDescriptorProvider to make use of Application parts.
* Simplified AddControllerAsServices to not accept any parameter and perform
controller discovery through the ApplicationPartManager in the IMvcBuilder
and IMvcCoreBuilder. Assemblies should be added to the ApplicationPartManager
in order to discover controllers in them.
This change renames IPropertyBindingPredicateProvider to
IPropertyFilterProvider. The changes here are mostly renames of
parameters/variables from predicate -> propertyFilter. I did a
find+replace and left the term 'predicate' in some of the docs because it
refers to a predicate in the abstract sense.
This change also simplifies BindAttribute and removes support for type
activation.
This commit introduces application parts as a concept on MVC.
An application part is an abstraction that allows you to expose some
feature or corncern in a way that is decoupled from their underlying source.
Examples of this include types in an assembly, emdeded resources, files on
disk etc.
Application parts are configured during startup by adding or removing them from
the application part manager available as part of IMvcBuilder and IMvcCoreBuilder.
The application part manager provides the ability to populate features from the
list of available application parts by using a list of application feature providers.
Application feature providers are responsible for populating a given feature given a
list of application parts.
Examples of application providers can be a ControllerFeatureProvider
that goes through the list of application parts, sees which one of those parts exposes types,
determines which of those types are controller types, and adds them to a ControllerFeature
that holds a list of all the types that will be considered controllers in the application.
* Introduce ControllerAttribute and use it to mark base classes as controllers.
* Changed rules for controller discovery to:
* All controller types must be public, concrete, non open generic types.
* NotController attribute is not applied to any type oif the hierarchy.
* The type name ends with controller.
* Controller attribute is applied to the type or to one of its ancestors.
* Moved instantiation of tag helpers into DefaultTagHelperActivator.
* Introduced ITagHelperFactory for handling the setup of new tag helper instances.
use authorization policies and requirements(IAuthorizationRequirement) to enforce authorization.
[Fixes#4233] AuthorizationFilterAttribute returns UnauthorizedResult rather than ChallengeResult
This change no longer suppresses validation for IFormFile and
IFormFileCollection model values. This will allow the use of [Required] on an
IFormFile model, or a custom attribute for validating IFormFileCollection.
These types already have ValidateChildren = false, so we don't recurse
into them.
This change separates model binding into IModelBinderProvider (decides
which binder to use) and IModelBinder (does binding). The
IModelBinderFactory is a new services with coordinates the creation of
model binders.
