circular symlink breaks typescript intellisense

[bedorlan]

Steps to Reproduce:

1. Before creating symlink, intellisense works:
   
2. Inside some project folder, create symbolic link to parent folder
   $ ln -s ../../ baselibs
3. Restart vscode
4. Now intellisense fails:
   

My project folder has 16942 files and 2944 folders. I try to reproduce the issue in a simpler folder structure, but i couldn't.

I also tried to ignore the symlink in the settings.json, but this doesn't fix the issue.

Gladly i'll provide more info.

@bedorlan thank you for reporting this issue. Is it possible for you to share your project so we can try and reproduce on our end?

@dbaeumer this is a tough one. He wasn't able to reproduce with a simpler structure. Any thoughts?

Finally, i was able to reproduce the issue. project attached.

project.zip

Steps to Reproduce:

1. uncompress project.zip & project.tgz (automatic symlinks)
2. open the folder project
3. open the file 0/1/2/test.ts
4. try intellisense

tip: i'm using a custom typescript sdk:

{
    "typescript.tsdk": "./node_modules/typescript/lib"
}

@waderyan pretty sure this is a tsserver issue. Since they load the whole project I don't know whether they 'normalize' links to avoid traversing the cycle endlessly.
