This change rewrites simple and safe Expression<Func<T, U>> expressions
into accesses to readonly fields. This allows us to cache the actual
expression and avoid repeatedly allocating and compiling it.
The rewrite is limited to cases where we know that the expression doesn't
capture, and where we support that kind of expression for evaluating
viewdata. In practice this means 'indentity' and property accessors are
allowed.
* Allow precompiled views to be served when source file does not exist in
file system.
* Cache results for views that do not exist on disk.
Fixes#2462 and fixes#2796.
Partially addresses #2551
- was trying out rules matching frequest PR comments (then)
- did a manual scan to find new instances of same issues
- "" -> `string.Empty`
- `String` -> `string` and similar
- fill empty XML doc elements
- ignored `JsonPatchDocument<TModel>`; just too many empty elements
- corrected missing / extra / out-of-order `<param>` descriptions
- `xml-docs-test` detects incorrect external references but not these local issues
- #1514
- refactor `RazorCompilationService` to allow a test subclass that normalizes Razor file line endings
- add `TestRazorCompilationService` to `RazorPageExecutionInstrumentationWebSite`
- adjust line endings to match in `RazorPageExecutionInstrumentationTest`
- add `ignoreLineEndingDifferences: true` to `Assert.Equal()` calls
- responses on Windows can have a mix of line endings
- `git config` setting affects line endings in .cshtml (and baseline) files
- however MVC and Razor mix `Environment.NewLine`s into HTTP responses
- update `PrecompilationTest` to split response regardless of line endings
- update `ResourceFile` to normalize all source file streams to LF only
- ensures consistent checksums and line mappings
- change `MvcRazorHostTest` to expect new line mappings
- recreate baseline files to expect new checksums and literal line endings
- use verbatim strings in affected tests
- careful use of `Environment.NewLine` in expectations is now just noise
nits:
- add doc comments in `RazorCompilationService`
- correct `TagHelpersTest` name to match containing file
- avoid incorrect `using` removal when `GENERATE_BASELINES` is not defined
- remove unnecessary `ResourceFile` normalization of output files
- ICodeTreeCache => IChunkTreeCache
- ModelCodeGenerator => ModelChunkGenerator
- MvcCSharpCodeBuilder => MvcCSharpCodeGenerator
- Updated files that used Razor resources that are now in different namespaces.
- Updated variable names to account for Razor renames.
aspnet/Razor#140
- also rename files and directories with "GlobalImport" in name
- nearly blind but avoid "ViewImportss" in new names
- public API change: `ViewHierarchyUtility.GetGlobalImportLocations()` -> `GetViewImportsLocations()`
- primary source updates were comments, tests, and implementation details
nit:
- rename NestedGlobalImports.cs file to NestedViewImportsController.cs, matching class
