- #3918
- don't repeat allocations for identical calls; helps w/ e.g. label / input / validation clusters
- add `NameAndIdProvider`; it stores `PreviousNameAndId` in `HttpContext.Items`
- `PreviousNameAndId` allocated only when `string`s are allocated e.g. "id"s were sanitized
* Removed unused private GetUrlHelper method in LocalRedirectResult class.
* Minor code formatting improvements.
* Fixed white space and casing of 'URL' in comment in RedirectResultExecutor.
- #3918
- lazy-load `TagBuilder.InnerHtml`; add `HasInnerHtml` property for conservative use
- depends on aspnet/HtmlAbstractions@0781b5a (adds `HtmlContentBuilder.Count`)
- don't use a `HtmlContentBuilder` at all in `DefaultHtmlGenerator.GenerateValidationSummary()`
- avoid instantiating `HtmlContentBuilder` when short-circuits make it unnecessary
- provide correct `HtmlContentBuilder` capacity where known
- #5347
- inconsistent bounds checking caused problems after `ArrayPool<char>` fell back to `new char[2048]`
- would fail a `Debug` assertion in Debug builds and loop endlessly in Release builds
- change to `CacheTagHelper+CharBufferHtmlContent` is for correctness only
- always uses a `CharArrayBufferSource` and that returns arrays of the exact size requested
- #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
