Webview doesn't load resources on WSL2 #105536

leandro-manifesto · 2020-08-27T21:42:52Z

Issue Type: Bug

Seems to be #101272, but that issue is locked.

It started happenning when I updated to 1.48 and happens most of the time when I open Git Graph.

Sometimes it does work properly but I still couldn't figure out why.

Does this reproduce in the latest VS Code insiders build build too?

leandro-manifesto · 2020-08-27T22:34:22Z

Just installed the latest insiders build and the problem didn't seem to happen.
And for some reason it started working again on the stable version too.
So I decided to test if restarting WSL with wsl --shutdown had any effect, and now neither of them work.

Seems that when I start either VS Code with the WLS 2 distro is already running it works, but when VS Code has to start the distro it doesn't.

By the way, I never use the terminal to start VS Code. It is always through the Windows executable shortcut.

@jghal

While this doesn't get fixed my workaround is to boot WSL with Windows Terminal before opening VS Code. Works every time.
If I forget about it, I close VS Code, open a cmd to run wsl --shutdown and do it over.

Hope this helps.

I'm having the same issues with the Git Graph extension:

Related: #106667, mhutchie/vscode-git-graph#378

allanbarklie · 2021-01-27T13:47:39Z

Just to note that I also see this defect current version info:

Git graph v1.28.0

Version: 1.52.1 (system setup)

V8: 8.3.110.13-electron.0
OS: Windows_NT x64 10.0.19042 (using WSL2)

For me the issue is intermittent- I haven't spotted any pattern about when it occurs.
Closing Visual Studio Code and opening it again always fixes it.

leandro-manifesto · 2021-02-09T19:33:43Z

Yeah, something changed on update 1.53.1 and now the workaround doesn't work anymore.
The only thing I didn't test yet was restarting the computer.

So I turned on --verbose and went searching for reasons for this and I found that loadLocalResource uses RequestService to load the resources:

[2021-02-09 17:02:32.017] [main] [debug] loadLocalResource - being. requestUri=vscode-webview-resource://6465c1a9-e4ba-483e-9c9a-822011f2fbbd/file///home/leandro/.vscode-server/extensions/mhutchie.git-graph-1.28.0/media/out.min.js

It seems the URI http://::1:45475/vscode-remote-resource?... is wrong because the correct way to specify a IPv6 in a URI is with brackets per RFC 3986.

Using Chrome to simulate the requests, http://::1:45475/vscode-remote-resource?... doesn't work but http://[::1]:45475/vscode-remote-resource?... does.

mjbvz · 2021-02-09T23:39:30Z

Very good find @leandro-manifesto! Ipv6 address could also explain why some people consistently see this while others don't (I don't seem to see it on my machine, but I'm running windows under parallels which may cause weird network things)

The problematic line is likely:

vscode/src/vs/platform/webview/electron-main/webviewProtocolProvider.ts

Line 172 in 5180973

path: '/vscode-remote-resource',

I'll look into checking in a fix but will likely need someone else to verify that it actually works.

For #105536 but need verification from someone who can actually reproduce this bug

mjbvz · 2021-02-09T23:53:21Z

Just pushed potential fix which will be in the next insiders build. Please test it out and let me know if this resolves the problem or not

leandro-manifesto · 2021-02-10T14:50:53Z

The current Insiders build is on commit cd97629, so I'm waiting for the new one to come out.

leandro-manifesto · 2021-02-10T21:07:58Z

Tested on this build:

Version: 1.54.0-insider
Commit: 40b3204
Date: 2021-02-10T17:39:27.208Z
Electron: 11.2.3
Chrome: 87.0.4280.141
Node.js: 12.18.3
V8: 8.7.220.31-electron.0
OS: Windows_NT x64 10.0.19042

Seems to be working. Git Graph opened properly.

Tested once with an already running WSL2, but it was using IPv4.
So I closed it, reset the WSL2 with wsl --shutdown, waited a while and reopened and it was using IPv6 this time with the brackets.

Each time I open VS Code it seems random if I'll get IPv4 or IPv6, don't know why.

mjbvz · 2021-02-11T23:54:56Z

Thanks for checking. Closing but please let me know if you see this bug using the latest insiders builds of VS Code

cmamigonian · 2021-02-19T13:22:22Z

What's the lead time for making this fix generally available?

barroudjo · 2021-02-19T14:09:40Z

I can confirm this fixes the issue in vscode insiders 1.54.0. And I can also confirm @leandro-manifesto diagnosis on vscode 1.53.2 as I also saw in the logs the ipv6 address without the [], resulting in 404s, when getting the js and css of git graph.

alexr00 · 2021-02-26T14:19:22Z

Looks like this has been verified by two of the original people who saw this issue. Thanks for verifying!
