- VSCode Version: 1.47.0, 1.48.0-insider
- OS Version: macOS 10.15.5
- Remote SSH: Ubuntu 18.04
Steps to Reproduce:
- Install vscode-R extension.
- Set
r.sessionWatcher to true, and reload vscode. - Use Remote-SSH to connect to remote Linux server (where R is installed).
- Install vscode-R extension to remote server.
Create R terminal and an R session is started- Run
?get
It starts an http server that provides the R documentation, and a VSCode
WebView should show up by the following extension code.
functionshowBrowser(url: string,title: string,viewer: string|boolean){console.info(`[showBrowser] uri: ${url}, viewer: ${viewer}`);if(viewer===false){env.openExternal(Uri.parse(url));}else{constport=parseInt(newURL(url).port);constpanel=window.createWebviewPanel('browser',title,{preserveFocus: true,viewColumn: ViewColumn[String(viewer)],},{enableScripts: true,retainContextWhenHidden: true,portMapping: [{extensionHostPort: port,webviewPort: port,},],});panel.webview.html=getBrowserHtml(url);}console.info('[showBrowser] Done');}functiongetBrowserHtml(url: string){return`<!DOCTYPE html><html lang="en"><head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <style> html, body { height: 100%; padding: 0; overflow: hidden; } </style></head><body> <iframe src="${url}" width="100%" height="100%" frameborder="0" /></body></html>`;}When viewer="Active", the WebView cannot be shown properly with the latest release and insider of VSCode. The iframe content is empty.
<iframesrc="http://127.0.0.1:22784/library/base/html/get.html" width="100%" height="100%" frameborder="0"></body></html></iframe>
However, if I run the following in R
.vsc.browser("http://127.0.0.1:22784/library/base/html/get.html", viewer=FALSE)which basically calls showBrowser with viewer=false, then a local web browser is open by env.openExternal(Uri.parse(url)); the web page is properly shown. Only after this, I call ?get, or equivalently
.vsc.browser("http://127.0.0.1:22784/library/base/html/get.html", viewer="Active")The WebView could be properly shown.
I guess the port mapping of WebView via Remote SSH somehow is not working and it works with the port mapping enabled by env.openExternal(Uri.parse(url)). Everything works well if the same is done locally.

Does this issue occur when all extensions are disabled?: Yes
