- Today `TagHelperContent`s always allocate their underlying buffer even though they typically only ever have a single entry. Added a field to enable us to only allocate the backing buffer when we absolutely need to.
- Removed `IsEmpty` from `TagHelperContent` since it was not used in any of our `TagHelper`s for simplification. Changed `IsWhiteSpace` naming to be `IsEmptyOrWhiteSpace` since it can be used to indicate either state.
- Updated tests.
#621
- Previously we'd do `executionContext.Output.Content = await executionContext.Output.GetChildContentAsync()`. The problem with this approach is that it returned a `Task<TagHelperContent>` which could not be optimized when building in release.
- Added test to validate `SetOutputContentAsync` does the appropriate thing.
#721
- `TagHelperOutput` and `TagHelperContext` lifetimes now mach `TagHelperExecutionContext`s. This means once a set of `TagHelper`s have run on a tag the `TagHelperOutput`/`TagHelperContext` will be re-used.
- Added tests to validate the various `Reset`/`Reinitialize` methods behaved correctly.
- Updated codegen to no longer set `TagHelperExecutionContext.Output`.
#719
- was missing when writing out full name of an `enum` value
- was missing in one case when writing out `TagHelperAttribute` type name
nit: updated `CSharpTagHelperFieldDeclarationVisitor.WritePrivateField()` to always include the prefix
- no change in generated code but centralizes the prefix addition and reduces intermediate `string`s
- After discussion offline to maintain consistency we decided to also remove `CodeBase` fallback in the net451 scenario. This will keep CoreCLR and net451 scenarios more consistent.
- Removed `CodeBase` validation tests.
- Added `GetAssemblyLocation` extensibility point to enable proper testing of the `TagHelperDesignTimeDescriptorFactory`.
#709
- Added the ability for users to opt into CSS `TagHelper` selectors in their required attributes by surrounding the value with `[` and `]`. Added operators `^`, `$` and `=`.
- Added tests to cover code paths used when determining CSS selectors.
#684
This change implements the new API for flattening content in Razor.
Also, some optimizations to avoid allocations on paths where we need
to encode HTML attribute values.
- 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
- Hoist `TagHelperAttribute` creation into `private static readonly` fields to avoid allocations on every request. With the recent `TagHelperAttribute` change that made them immutable we can now pre-allocate them without worry of them being modified.
- Added two extra class configuration pieces to enable pre-allocation.
- Updated test files to showcase new pre-allocations.
#600
- Currently the `TagHelperScopeManager` creates a new `TagHelperExecutionContext` per `TagHelper` on a given page. With this change the max number of `TagHelperExecutionContext`s per page is the number of nested levels that exist.
- Added two tests validating that specific pieces of `TagHelperExecutionContext` are updated as expected.
#674
- Changed the variable used to render templates (`HelperResult`s) so they can be used inside of sections.
- Updated section test file to showcase nested scenario. Also Regenerated existing test files.
#572
- Not all `TagHelper`s have unbound HTML attributes or any attributes at all. A great example of this is MVC's input `TagHelper` which usually takes the format of `<input asp-for="..." />`. By lazily initializing we don't build extra attribute lists where not needed.
- Moved `TagHelperContext` and `TagHelperOutput` creation to CreateX methods on `TagHelperExecutionContext`.
#604
- Remove a lot of the ugly generic work done in `TagHelperAttributeList`/`ReadOnlyTagHelperAttributeList`.
- Removed error cases where we'd check on addition of `TagHelperAttribute`s that their `name` was not `null`. This was due to the pre-existing `string` indexer for `TagHelperAttributeList`. It no longer sets `TagHelperAttribute`s directly, instead it's `[key] = value` (instead of `[key] = new TagHelperAttribute(...))`.
- Updated tests to account for new immutability/string indexer format.
- Removed copy ctor from `TagHelperAttribute` since its immutability kills the value.
- Changed `ReadOnlyTagHelperAttributeList` to inherit from `ReadOnlyCollection`
#604
This change 'flattens' a TagHelperOutput when writing it out to an
HtmlTextWriter. This is a beneficial perf change because more often than
not the thing being written to is a ViewBuffer in Razor, which uses pooled
memory. This allows us to 'join' islands of pooled ViewBuffer memory back
into the main buffer instead of keeping them wrapped up in a
TagHelperOutput or TagHelperContent.
