VS Code fails to start/open when offline

[johnnyPescarul]

• VSCode Version: 1.2.0
• OS Version: Windows 8

Steps to Reproduce:

1. Install VS Code 1.2.0 and open first time while connected to internet
2. Turn off data connection
3. Try to restart VS Code (it does not open at all, either from shortcuts or exe)

@johnnyPescarul any output when you try to run code --verbose from the command line in this case?

[johnnyPescarul]

@bpasero Sorry for the late reply, I didn't see the notification. I tried running "code --verbose" from command line and still nothing, not even one line. As soon as I connect to the internet, it works. I tried re-installing multiple times but I have the same behavior. I tried to replicate on a Windows 7 machine, but was not able to (so it seems to be limited to my Windows 8 machine).

@johnnyPescarul does it return immediately when running "code --verbose"?

[johnnyPescarul]

@bpasero when I run it, it starts the process but it then hangs. It must be something early on since nothing is displayed with verbose flag on. Are there any logs generated?

[bpasero]

@johnnyPescarul any chance you could find out all the processes that we are able to spawn? this might get us closer to see where it hangs.

@joaomoreno could this be an issue with creating a connection to the shared process if you are offline?

[joaomoreno]

@bpasero Why the shared process? The window doesn't even seem to open...

[bpasero]

@joaomoreno the shared process (to my understanding) gets created from the main side. we have seen super funky behaviour when sending telemetry where the entire VM stops in some DNS lookup. Maybe the main side stops in a similar situation trying to establish a connection to the shared process.

[joaomoreno]

Very unlikely. The main process doesn't even connect to it, simply spawns it. It would only block if fork blocks... and even then the user would read '### VSCode main.js ###' in his console.

[johnnyPescarul]

I tried again to see if any processes are actually started, but no VSCode process is being started at all, when trying to start in offline mode. Unfortunately I don't have another Windows 8 machine to try and see if I can replicate the issue.

[bpasero]

@johnnyPescarul can you run code --version and see output?

[johnnyPescarul]

@bpasero it is version 1.2.0
Again, if the laptop is offline, the code --version doesn't even work (nothing is displayed).
