The instruction matcher was missing a few details, which made it faster
than it should have been. Right now I'm trying to keep the design of
these in sync. Once I fixed that it exposed a legitimate bug that was
blocking the github benchmark.
This change improves this area a bit by consolidating the matcher
implementations between the benchmarks project and the conformance
tests.
Additionally I split the minimal matcher into a really trivial
implementation for the simple tests and a more complex one for the
larger tests. This allows us to keep the plaintext/techempower scenario
in sight while also having a good baseline for the more sophisticated
tests.
Also starting to add tests that verify that matchers behave as expected.
The matchers now successfully execute all of these benchmarks, which
means that they support literals and parameters.
Missing features:
- complex segments
- catchall
- default values
- optional parameters
- constraints
- complex segments with file extensions
This is a good place to iterate a bit more of perf and try to make a
decision about what we want to implement.
A common cause for runtime view compilation failure in MVC is when an application is published
without reference assemblies. MVC usually handles this at compilation, by looking for specific
error codes. More recently, TagHelper discovery fails with an not-so-helpful error message in this
scenario. This change attempts to add a little more error checking to cover the most common cases
- Allow identical `@using` directives in the primary document. This means that if a user types `@using System` twice in the primary document (i.e. `Index.cshtml`) then we'll generate that using statement twice; this enables proper C# IntelliSense to light up on both using statements and allows auto-completion to work because there's no more magical distinction logic for Razor code that is in the current document.
- Prior to this change if you had two identical using statements in the same document one would be in no-mans land mapped to nothing (not C#, not HTML) and the other would be mapped to C#; the second a user differentiated the two statements (i.e. adding a `.`) we'd distinctify the using statements resulting in an invalid completion.
- This PR has an end-user impact where they will now receive the normal C# warning about having duplicate using. I treated this prior behavior more as a bug because we threw away the first using directive instance which impacted editing and in general was a silly thing to correct for the user.
- Added new integration test showing how using directives are not de-duplicated in the primary document.
#1255
- This is part of a fix for #1255 - this change enables signature help in implicit expressions by improving the partial parsing. We're now smart enough about the contents of an implicit expression and attempt to balance parenthesis to determine if we should not full parse.
