TSServer Crashes When Opening Sharepoint Folder

[mjbvz]

TypeScript Version: 2.1.5

We're seeing a large number of reports of TSServer crashes from VSCode users when they attempt to open a project stored on sharepoint. I can repo this by opening a simple sharepoint folder with a single empty js file on windows.

Here's an example trace of the communications from VSCode:

Imho this fix should be backported to 2.1.x so that we can do a recovery build. We are seeing a lot of issues reported for VS Code.

Does this TypeScript issue's resolution fix issue 19870 as well? That problem occurs for any js file, even with the TypeScript extension removed, yet it was closed last week as a duplicate of this issue.

microsoft/vscode#19870 is rather scarce on details, but seems like the same symptoms.

The JavaScript language service in VSCode is driven by the TypeScript engine. The problem is really caused by a bug in libuv libuv/libuv#1221. We have a mitigation in place in typescript@2.1.6. The VSCode team is looking for releasing a new build with the fix shortly.
