- Updated `LocationTagged<TValue>` to handle `null` implicit values.
- Removed `InternalsVisibleTo` declaration on `Microsoft.AspNet.Razor` to the runtime test project.
- Updated `TagHelperDescriptor` tests to utilize helper methods to construct `TagHelperDescriptor`s. This was needed since the `InternalsVisibleTo` declaration was removed.
#449
- add `[NotNull]` in some `public` or `protected` callers as well
- add `[NotNull]` in `SeekableTextReader` constructors
- add `where TSymbolType : struct` to replace incorrect `null` checks
- remove `T` type parameters in changed files e.g. change to `TWriter`
- remove tests of removed code
nits:
- change `TextReaderExtensions` to consistently call other extensions as statics
- wrap some long doc comments
- #362 and more
- make a few more properties immutable
- in a few cases, just remove `private` setters
- in others, adjust consuming code to handle the changes
- make `Equals()` commutative
- use `GetType() == obj.GetType()` if necessary
- use only immutable values in `GetHashCode()` calculations
- avoid `object.GetHashCode()`; that calculates hash of reference
- add warnings about `RazorError` property setters but use properties
- BUT lack of immutable values leads to some static `GetHashCode()` calculations
- correct important typo in `TagHelperDescriptorComparer`
- ensure `Equals()` does not `throw` an NRE e.g. in `LineMapping`
- add `SyntaxTreeNode.GetEquivalenceHash()`
- make `SourceLocation.Equals()` and `SourceLocation.CompareTo()` consistent
Update affected tests
- code generators and edit handlers less likely to be equal; adjust expectations
Add lots of tests
- not for all updated classes but enough to see impact of odd choices
nits:
- remove some `Equals()` and `GetHashCode()` overrides in `SpanCodeGenerator` subclasses
- no longer unique
- remove redundant null checks e.g. when also done in `base.Equals()`
- add `StringComparer.Ordinal` if `StringComparison.Ordinal` used in `Equals()`
- make some `CSharpLineMappingWriter` fields `readonly`
- remove unused `LineMapping` constructor
- #320
- `ParserErrorSink` -> `ErrorSink`
- move `ErrorSink`, `RazorError`, and `SourceLocation` to root namespace
- move `RazorErrorTest` and `SourceLocationTest` to root test namespace
These types are allocated for every state transition in the parser (State)
or every character that's read (character reference) and are fairly
compact. Turning them into structs will remove a significant number of unnecessary
allocations in the parser.
For our razor code generation benchmark, making these changes yields about
500-750ms of speedup (out of 40000ms) or about 1%.
This addition will eventually replace CodeDOM to allow for the k10 project to build. It is a new type of codegeneration method that is highly extensible.
