This change implements version tracking the inputs and outputs of
generated code.
Version tracking is still best-effort - meaning that in some cases a
perfect system could avoid doing more work. However, since we base the
versions off of all of the inputs, we now that the guarantee that code
generation operations that happen 'out of order' will always result in
the newer inputs generating the newer outputs.
Fixes: https://github.com/aspnet/Razor/issues/2650
This change adds mock ups of the interfaces that we've been designing as
part of Razor FAR as well as the implementations. This isn't wired up to
anything yet in this PR, but the basic functionality here is stable
enough for us to stabilize and review.
For now we have the interface definitions in the Razor codebase until a
build of Roslyn is available with these definitions + IVT for us to use
them.
We want to have a way to specify the taghelper descriptors and imports to use while
processing a specific document.
- Added an overload to Process and ProcessDesignTime to take in a list
TagHelperDescriptors and a list of imports
- Added the corresponding CreateCodeDocumentCore overload
- Added GetTagHelpers and SetTagHelpers extension methods for
CodeDocument
- Added the necessary plumbing to use the taghelpers from the
CodeDocument when available and fallback logic.
- Added DocumentImportsTracker and updated background code generation
logic to use the new overload
- Added/updated tests
This change intoduces content changes to our project snapshots. We now
know the open/closed state of documents that are initialized by the
Razor project system and listen to the correct data source based on
whether the file is open in the editor.
There are a few other random improvements in here as well like a
workaround for the upcoming name change to our OOP client type.
The project snapshot now maintains a RazorProjectEngine as well as set
of Tag Helpers that are known for that snapshot.
Pivoted some more services to be snapshot-centric.
Also added the ability to track .cshtml documents to the project system.
For now most components just ignore document changes.
