- #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
This addresses #1051. There is one more pull request that needs to be completed/merged (for `CompositeTagHelperDescriptorResolver` and friends). After that, runtime should work!
- #4988
- preserve whitespace as the setting demands
- correct previous `string.IsNullOrEmpty()` call to match previous `ValueProviderResultExtensions.ConvertTo()` use
- short-circuit other `string`-to-`string` conversions (as `ValueProviderResultExtensions.ConvertTo()` does)
- correct documentation of `ConvertEmptyStringToNull` properties
- add more tests of these scenarios and remove duplicate `BindModel_ValidValueProviderResult_ConvertEmptyStringsToNull()` test
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
'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.
- #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`
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 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.
- #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
* 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.
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.
- #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
- unrelated to #3482 except that I discovered the issue while investigating that issue
- tests previously set `BindingDetails.IsReadOnly` for a `Type` and that was ignored
- same for `DictionaryModelBinderTest`
This undoes a behavior change introduced in
7b18d1d3f1.
The intent was to have ClearValidationState do the right thing for a case
where a collection was bound to the empty prefix, and then used again with
TryUpdateModel.
This change was implemented by saying that a key like "[0].Foo" is a match
for the prefix of "Foo". This isn't really right, and it's only
interesting for the ClearValidationState case.
The problem is that we don't know what the keys look like for a
collection. We can assume that they start with [0] but that's not really a
guarantee, it's a guess.
This change fixes the behavior of StartsWithModel, and move the
responsibility for this case back into ClearValidationState.
This change also removes the call to ClearValidationState from
TryUpdateModel. If you need this behavior, then call ClearValidationState
manually. Trying to bind and then re-bind a model object isn't really what
we intend.
* Broken InputFormatter into InputFormatter and TextInputFormatter
* Added an exception to ModelState inside ReadAsync on TextInputFormatter
when we can't find a valid encoding to read the body.
