The fix splits client validation and model validation into two separate hierarchies.
Introduced ClientModelValidatorProvider in MvcOptions, which can be iterated to produce IClientModelValidators.
As a result of this, HtmlGenerator code can be free of ActionBindingContext and directly consumes options.
This also means that we do not modify the client validations during resource filters.
- remove useless `configuration` variables and `Configuration` instances
- remove "Review" code comment
- unintentionally included in commit 4b5dd19
- reduce repeated code in `TestHelper` for functional tests
- `CreateServer()` methods had duplicate code, an ambiguous match, and an odd order
- rename `GetTestConfiguration()` to `UseCultureReplacer()` in functional tests
The DataAnnotationsMetadataProvider was setting the bool? IsRequired, all of the
time instead of only setting it to true when we found a RequiredAttribute.
So we never actually executed the fallback logic here. Found
this while working on removing some reflection code from the validator,
and wanted to split it out because it's simple.
This change removes reflection from validator providers, and instead
relies on cached metadata in in the modelmetadata.
In general this means that our MVPs don't need to cache anything, they
just look at the metadata and create what they need.
In the case of data-annotations, we update the model details provider to
add validation attributes to the modelmetadata. This would allow someone
to replace the DataAnnotationsValidatorProvider, but still use the
metadata in these attributes.
The change to the IModelValidatorProvider api (to use a context) is
intended to minimize allocations. Currently each validator provider needs
to return a list so you end up with N+1 lists (N validators + a final list
to compine them all). This change will let us just create the final list
(and a small context object). This is a very very high traffic API so it
seemed worth doing.
There's also some general massaging of namespaces and file locations.
These model binders don't have any per-request state so there is no need
for them to be type activated. In one case the model binder actually does
its own caching which is being defeated by the fact that we register it as
type activated.
More changes to come in this area.
- see issues aspnet/DependencyInjection#193 and #1612
- use `TryAdd()` in `MvcServices` for the `IAssemblyProvider`
Move `ApplicationBasePath` handling into `RazorPreCompileModule`
- restores view precompilation in functional tests of sample sites
- if we need this, others will as well
- override `IApplicationEnvironment` but get folder from `ProjectContext`
- also remove remaining `IServiceProvider` implementations in this code
test fixes:
- simplify `IApplicationEnvironment` override
- move override logic into `TestHelper.CreateServer()` methods
- remove `LoggerFactory` setup
- does not seem to require special-casing
- remove unused `ITestConfigurationProvider` / `TestConfigurationProvider`
- remove `TestAssemblyProvider` classes
- no longer required
- remove `ReplaceCallContextServiceLocationService` test helper
- change MVC sample to fully-qualify config.json path
- avoids `ReplaceCallContextServiceLocationService` need in `MvcSampleTests`
- no longer required for other tests
nit: remove unused `_serviceProvider` and constructor overload in `RazorPreCompiler`
Separates the MMP into two phases:
1). Creation of the ModelMetadata, discovery of properties and attributes
(reflection) is part of the MMP
2). Lookup of details based on attributes is now part of another phase,
and has its results cached.
Users can now implements and register an IFooMetadataProvider to customize
a single aspect of metadata (see how data annotations does it).
This change provides caching for the results of searching for view
components and discovering their names.
In our ViewComponent perf test, selecting the component type was about 25%
of the execution of MVC (due to uncached reflection). This change brings
that down to about 1%.
This is a small change to remove uncached reflection. There are some other
code paths where use of view components results in a hotspot. Leaving
those issues to be tracked as part of a larger design issue.
This also fixes#1503.
Currently all model binders except mutable object binder are independent of validation code. The mutable object binder which needs to do some validation ( for scenarios involving [BindRequired] and [BindNever]).
We would be going with an approach where required validaiton happens in input formatters and model binders.
This is needed as validation for value types can best be done at creation time.
Followup PRs:
Introduce support for skipping validation (and not binding) for a particular property/type etc.
services
* Added WithControllersFromServiceProvider that replaces the default
controller activator with a service based one.
* Move activation to DefaultControllerFactory
* Modify [Activate] behavior so that it no longer activates services. Use
[FromService] attribute to hydrate services
Fixes#1707
The modelmetadataprovider does significant reflection caching, which shows
up as a hotspot. It's only of our most commonly used services, so not only
do a TON of instances get created, they are very heavy-weight because of
the two ConcurrentDictionary instances they have.
1. Creates a filter called FormatFilter. This will look at the format parameter if present
in the route data or query data and sets the content type in ObjectResult
2. It adds new options called FormatterOptions, that contains the map of format to content tyepe
3. A method in MVC options to add the formatter mapping
- add a couple more exclusions to .gitignore (recent VS additions)
- remove `<ProjectExtensions/>` elements
- update files that don't have the correct output directories
- remove dangling PrecompilationWebSite.kproj file
This is a demonstration of how to inject an IRouter in between traditional
routes and MVC's handler. This allows you to accomplish a variety of
things that were possible with WebAPIs handlers, but inside the routing
system.
The example here turns a header representing the user into a locale, which
is used to select a controller. You could do other things like reject the
route match or change link generation.
There is one subtle project change here, to allow the same to be possible
for attribute routing, we need to create the attribute route after running
the user's routing configuration code.
- Support for binding posted file to type IFormFile
- Support for multipart/form-data in FormValueProviderFactory
- Updated Mvc Sample
- Added relevant unit and functional tests
This is a new filter stage that surrounds the existing model binding,
action, and result parts of the pipeline. Resource Filters run after
Authorization Filters.
The other major change is to support one of the primary scenarios for
Resource Filters. We want a filter to be able to modify the inputs the
model binding (formatters, model binders, value providers, etc) -- this
means that those changes need to be held on a context object and preserved
so that they can be used in the controller.
So, IActionBindingContextProvider is removed - the ActionBindingContext
will be created by the invoker. For now it will be part of the action
context.
- StyleCop working again (handles C# 6.0 additions) though only locally for me
- disable some new rules:
- ConstFieldNamesMustBeginWithUpperCaseLetter
- InstanceReadonlyElementsMustAppearBeforeInstanceNonReadonlyElements
- StaticReadonlyElementsMustAppearBeforeStaticNonReadonlyElements
- StaticReadonlyFieldsMustBeginWithUpperCaseLetter
- PrefixCallsCorrectly
- correct remaining violations
- lots of long lines for example
- use more `var`; some manual updates since StyleCop doesn't check seemingly-unused blocks
nit: remove new trailing whitespace (was paranoid about adding it w/ fixes)
- #EngineeringDay
- VS does not yet format auto-properties nicely; reverted what it did
Also revert changes under
- test/Microsoft.AspNet.Mvc.Razor.Host.Test/TestFiles
- #EngineeringDay
- Total replaced: 660 Matching files: 270 in *.cs
- Total replaced: 250 Matching files: 32 in all other files
- Total replaced: 22 Matching files: 8 in a few stragglers
Did not change files under following directories
- test\Microsoft.AspNet.Mvc.Razor.Host.Test\TestFiles\Output
- test\Microsoft.AspNet.Mvc.FunctionalTests\compiler\resources
- test\WebSites\TagHelpersWebSite
(Razor generates trailing whitespace in a case or two)
This also comes with a rename of the namespace
Microsoft.AspNet.Mvc.ApplicationModel to
Microsoft.AspNet.Mvc.ApplicationModels.
Also tuned up some parameter and variable names for increased
understandability.
Fix: The MvcOptions takes in a list of ExcludeFromValidationDelegate (Func<Type,bool>). This func verifies if the type is excluded in validation or not.
