TSServer 2.0.6 fails with filenames without an extension

[dbaeumer]

TypeScript Version: 2.0.6

Code

File bin\compile (note the file has no extension)

#!/usr/bin/env node

console.log('')

Opening the file and requesting a language feature (hover, code complete) results in an exception in the tsserver:

This worked without problem with TS 2.0.3

@mhegazy @vladima could you please look into a fix. This is a regression and we should look into fixing this for VS Code 1.7 which ships mid / end next week.

[vladima]

@dbaeumer I cannot repro it as-is by just creating file without extension and opening it. However in the log I can see that you also have config file p:/mseng/VSCode/vscode-extension-vscode/tsconfig.json. Can you also paste it here?

[dbaeumer]

The tsconfig.json is:

{
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs"
    },
    "exclude": [
        "node_modules",
        "vscode.d.ts",
        "typings"
    ]
}

You can also clone: https://github.com/microsoft/vscode-extension-vscode

[vladima]

@dbaeumer We've fixed the original issue in master however at this point 2.0.5 is already locked and it is pretty hard to put anything there. As a workaround on your side you can:

• set internal option allowNonTsExtensions to true in compilerOptionsForInferredProjects request
• don't send compilerOptionsForInferredProjects at all - default compiler options on the tsserver side already have allowNonTsExtensions being enabled

[mhegazy]

Should be fixed by #11922 in TS 2.1.2

[dbaeumer]

@mhegazy could this be backported to 2.0.6. We ship 1.7.x this week and this is basically a regression for us.
