Insiders: exthost.log file already exists

[joaomoreno]

Just starting my Insiders gives me this:

@sandy081 Let me know if you need more info.

Thats a great catch buddy, this is because I am not checking if file existence before creating it.

I also revealed another bug while investigating this - Web worker extension hosts across windows are using the same log file as I am not scoping it to window while creating. See the first entry exthost.log in the following picture - this is the single log file that all web worker extension hosts are logging to.

Also fixed this by pointing web worker ext host logs to a new folder webWorker under extHost{windowId}

To verify:

• Enable web worker ext host using setting "extensions.webWorker": true
• Restart VS Code
• Open Developer tools console and make sure there are no errors like in description
• Run command Open Extensions Log Folder and make sure web worker ext host log is in separate folder webWorker
