Oh yeah I noticed this too, I have to keep refreshing the explorer.

[jsjoeio]

Do you have any ideas on what might cause this? I'm not too sure where to look 🤔 But I'll look into this tomorrow.

I feel like it must be in the file watcher somewhere, I think maybe the first thing would be to make sure it is picking up changes in the workspace.

Okay looking into this now.

Ensuring the file watcher picks this up

1. run code-server 4.0.0 with the -vvv flag
2. open workspace/folder
3. create new file in the terminal: touch yo.txt
4. look at server logs

Logs:

[13:55:28] [File Watcher (parcel)] [ADDED] /Users/jp/Dev/repros/cs-4630/yo.txt
[13:55:28] [File Watcher (parcel)]  >> normalized [ADDED] /Users/jp/dev/repros/cs-4630/yo.txt

This means the File Watcher is seeing this change. That's a good first step. Not sure why the File Explorer isn't rendering this in the view.

I'll update this comment with more notes.

Comparing with upstream

I see a flag called fileWatcherPolling upstream. Maybe that value is missing?

Nope.

Looking at the explorerService

This looks useful: https://github.com/microsoft/vscode/blob/main/src/vs/workbench/contrib/files/browser/explorerService.ts#L79-L80

For some reason it can't find the parent for the new resource 🤔

Digging deeper and looking at _foldersMap, we've learned that the folder is missing the authority but the resource has it. Not sure why 🤔

This happens again for me. I freshly installed 4.0.1 on Debian 11 via the install script. Then I run it as

mkdir wd && code-server --bind-addr 0.0.0.0:8080 --auth none wd

Once connected with the editor, I open the integrated terminal and type

touch afile.txt

but nothing appears in the explorer. If I reload the page afile.txt appears in the explorer, and the following message (among many others) appears twice in the console log of the browser

WARN [File watcher]: started ignoring events due to too many file change events at once 
(incoming: 1, most recent change: vscode-log:/20220118T092634/window.log). 
Use 'files.watcherExclude' setting to exclude folders with lots of changing files 
(e.g. compilation output)

I've tried playing with files.watcherExclude adding whatever seemed reasonable, such as

"files.watcherExclude": {
  "**/.local": true,
  "**/.vscode-remote": true
}

but it doesn't seem to make any difference.

Any help will be appreciated, meanwhile I'll revert to 3.12.0 (that under the exact same circumstances doesn't show the bug).

Thanks for reporting! We'll see if we can reproduce!

I have the same problem with Explorer on 4.0.2 and in addition, changes to an open file are also not immediately displayed when I have made changes to it via the terminal. This complicates the work sometimes considerably.

The cause is probably the same.
