Project cache invalidating

[vasily-kirichenko]

It does not work yet. The following exception is raised after renaming a file:

There are 1 error(s).
[Language Service] System.Exception: Could not find requested input '(startup (1,0--1,80) IsSynthetic=false, "L:\git\Library3\Library1.fs", false)' named 'FileNames' in set [(0, Available('(startup (1,0--1,80) IsSynthetic=false, L:\git\Library3\Library11.fs, False)' as of 26.02.2014 22:45:36)); (1, Available('(startup (1,0--1,80) IsSynthetic=false, L:\git\Library3\File51.fs, True)' as of 26.02.2014 22:45:36))]

This must be an FCS bug. Dave Tomas saw something similar in Xamarin Studio

No, it's not an FCS bug (though it's a bad error message) - it's because somehow you're asking for information about a file L:\git\Library3\Library1.fs that isn't known to the project results being interrogated. Presumably that's the added or renamed file?

Do you call InteractiveChecker's InvalidateConfiguration for the project that has had the change? I believe you need to do that.

[vasily-kirichenko]

@dsyme thanks! I'll try to add a InvalidateConfiguration call tomorrow.

[vasily-kirichenko]

I call InvalidateAll instead and the exception has gone.

I'm not sure doc.ProjectItem could be null in some case.

[vasily-kirichenko]

Initialize is called from here https://github.com/vasily-kirichenko/FSharpVSPowerTools/blob/project-cache-invalidating/src/FSharpVSPowerTools/PowerToolsCommandsPackage.cs#L47

If I uncomment instance.Force() then we won't receive any events. So, it effectively works as before.

[vasily-kirichenko]

@dungpa Fixed.

[dungpa]

Nice updates.

[ghost]

Using InvalidateAll is a bit brutal, can you invalidate the single project?

[vasily-kirichenko]

@dsyme Fixed. #83
