Language service doesn't start at all, then partially, then finally fully #10056

Open Peter-Juhasz opened 3 months ago

Peter-Juhasz commented 3 months ago

VS 17.10.0 P1

Sometimes it is a gambling what language service capabilities are available when I open a file:

https://github.com/dotnet/razor/assets/9047283/b8c53b5c-6e87-40ab-956d-86d60a50c119

  1. No language service works: no quick info, no completion, even syntax highlighting works only partially.
  2. Some services start: syntax highlighting, quick info, completion, reference highlighting, but still there is no outlining/structure.
  3. All works finally.

These are all the errors from logs:

It seems to be related to #9986 but although the symptoms are similar, this is another error. And the file I copied was a long time ago, although the error message talks about "Details.razor - Copy.razor" which doesn't even exist.

Related to #10021 as well, but different, because in that case there were no logs at all, it was another combination of services stopped, and in that case there was no copying at all involved.

@Peter-Juhasz could you do us a favour and log this issue through VS Feedback, and include a recording of the issue? That will capture a memory dump and ETL traces that hopefully will help us diagnose what is going on. If you set the LogLevel environment to All before running Visual Studio, that would be even better!

I'm hoping this is another instance of https://github.com/dotnet/razor/issues/10007 which is fixed in the next preview.

Unfortunately, I'm not allowed to create a memory dump, but if you work with a medium size project day to day, it should come up quite often.

But here is another error, which I have not seen yet:

9:05:41.945 [LSP][LanguageServer.DocumentContextFactory] Tried to create context for document S:/REDACTED.razor and project S:/REDACTED/obj/Debug/net8.0/ which was not found.

The symptom is that some types are not recognized (in C# ranges), and none of the Razor components. After some time, types got recognized, but still, none of the components.
