- #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
- #5317
- previously worked only because `TagBuilder` cannot be empty and `HtmlString` overrides `ToString()`
- `TagBuilder.ToString()` (now the type's `FullName`) is also never empty
- copy `NullHtmlEncoder` from Razor and give it a better name (`PassThroughHtmlEncoder`)
- not available in this project and (from its namespace) not intended for general use
- #5313
Also:
- preserve existing `TagHelperAttribute.ValueStyle`
- fix this in `UrlResolutionTagHelper`, `LinkTagHelper`, and `ScriptTagHelper` as well
- correct handling of non-`string` `classAttribute.Value`s in `TagHelperOutputExtensions`
- relates to #3918 because new `ClassAttributeHtmlContent` is smaller than any concatenated attribute value
nit: clean up `CacheTagHelper` whitespace and `using`s
- #5028
- helpers similar to our HTML or tag helpers can use the new singleton to examine or add validation attributes
- in the most common case, helpers add validation attributes to a `TagBuilder`
- separate `DefaultValidationHtmlAttributeProvider` from `DefaultHtmlGenerator`
- avoids creating two instances of the `DefaultHtmlGenerator` singleton
- would be even uglier to require callers to cast an `IHtmlGenerator` to `ValidationHtmlAttributeProvider`
- `[Obsolete]` old `DefaultHtmlGenerator` constructor
- #5209
- update affected `HtmlHelperValiationSummaryTest` and functional tests
- add `ValidationSummaryTagHelperTest` tests to cover related scenarios
##### Behaviour changes when no errors exist for the model:
###### Tag helper
``` html
<div asp-validation-summary="ModelOnly" class="order"><h3>Oopsie<h3></div>
```
previously generated
``` html
<div class="order validation-summary-errors"><h3>Oopsie</h3><ul><li style="display:none"></li>
</ul></div>
```
and now generates
``` html
<div class="order"><h3>Oopsie</h3></div>
```
###### HTML helper
``` c#
@Html.ValidationSummary(excludePropertyErrors: true, message: "Oopsie")
```
previously generated
``` html
<div class=\"validation-summary-errors\"><span>Oopsie</span>
<ul><li style=\"display:none\"></li>
</ul></div>
```
and now generates nothing (`@HtmlString.Empty`).
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
- consolidate `ButtonTagHelper` and `SubmitTagHelper` into `FormActionTagHelper`
- consolidate `ButtonTagHelperTest` and `SubmitTagHelperTest` into `FormActionTagHelperTest`
nits:
- do not allocate dictionaries in the `<a>` or `<form>` tag helpers unless needed
- clean up some hard-to-maintain whitespace
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.
