Live-share: [VS Code] Live Share Spawning lots of git commands slowing down the machine

[viniciusmelquiades]

Product and Version [VS/VSCode]: VSCode 1.29.1
OS Version [macOS/Windows]: Windows 10 build 1803
Live Share Extension Version: 0.3.1002
Target Platform or Language [e.g. Node.js]: Not applied

Steps to Reproduce / Scenario:
I noticed my machine slowing down drastically, and my CPU usage high, and tracked it to VS Code. I noticed it was running LOTS of "git.exe show" commands.
After I disabled some extensions I tracked the problem to Live Share.
I could not get Live Share logs as the machine slowed down too fast.
I notice the problem started happening between a VS Code restart. Probably because an automatic update.

To reproduce:

1. Install the version I specified above.
2. Open any repository. I don't know if the number of commits matter. Mine had 139 commits.
3. See your process tree and note all the git commands running. (The print below is from Process Hacker)

I'm having the exact same problem on macOS. Opening a git differential view would take forever and completely redline the cpu with tons of git processes spawned. Disabling vs live share extension fixes it. My specs:

os: MacOS (Darwin 18.2.0)
VsCode: 1.29.1
VSLIve share version: 0.3.1002

@Priya91 @rodrigovaras FYI - I just saw this happen myself. To help repro, I had GitLens, the GitHub Pull Request extension, and Live Share installed. Uninstalling the GitHub Pull Request extension seemed to resolve the problem for me. The GH extension seemed to update around the same time since I saw a notification pop up that I was not signed into GitHub for the first time.

@Priya91 @rodrigovaras Scratch that - it started happening again after being okay for several minutes.

That's horrible.. VSCode on Linux just slows down and it's unusable. I removed it completely and problem resolved :D
It's started actually today, yesterday was everything fine.

@TheAifam5 Yes - we're working on a fix now. There appears to be a specific scenario that causes it. For me, only one repo I have on disk causes it to happen while all others work fine. I just happened to stumble on it.

Exists also on macOS. Because of this issue the intellisense stopped working and extensions are reloading all the time in a loop. After disabling live-share everything works again.

Thanks - This is a confirmed bug for 0.3.1002 specifically and affects all operating systems. Fix is in progress.

[Chuxel]

This should be fixed in the bits that were released in the last 30 minutes. Let us know if you still see the problem in 0.3.1005!

It still runs a lot of git commands, but id doesn't seem like it's all at once, and they stop after a few seconds. I'd say this is fixed. And that was fast too! Thanks.

@viniciusmelquiades Great! Yes, the impact of this bug was severe enough we felt it warranted an emergency release. Thanks so much for reporting it!
