Comparing with remote workspace folder fails

[mforkel]

I tried to use Compare Folders in a workspace that contains local folders and remote folders accessed with the SSH FS extension. An attempt to compare a local folder to a remote folder results in an error message "Oops, something went wrong while comparing" and this output:

error while comparing
{
  "errno": -2,
  "code": "ENOENT",
  "syscall": "lstat",
  "path": "/scripts"
}

Comparing a local folder to the remote root folder gives this output:

error while comparing
{
  "errno": -13,
  "syscall": "lstat",
  "code": "EACCES",
  "path": "//mnt/c/DumpStack.log.tmp"
}

The file DumpStack.log.tmp is not accessible. In both cases, Compare Folders incorrectly report that there are no differences in any file at the same path.

Comparing a file in a local folder to a file in a remote folder works fine.

The SSH FS documentation for remote workspace folders claims that SSH FS works with extensions using the vscode.workspace.fs API. May be Compare Folders is no using that API?

Thanks for the report.
I'll look into it as soon as I can.

Same here. I was trying to compare two folders on the remote server and it took forever to load. The same folders on my local laptop work smoothly.

Hi @qiyan98 and @mforkel .
Sorry for the very late reply. I'm not using remote folders so I lack knowledge in that area.
I'm not sure it's related but the extension uses an external library for comparison. I'm sure that the library doesn't use vscode.workspace.fs API because it's a normal node library.
Maybe I can ask the librarys owner to allow consumers to pass the fsmodule so in our case it would usevscode.workspace.fs.

Do you know an easy way to connect to ssh so I could test it myself?

Thanks for looking into this, moshfeu

I'm not sure I understand your question. I guess a basic setup for testing would be a remote machine with an SSH server installed and your Windows machine with VS Code and the Remote SSH extension (see Remote Development using SSH). Then you could use your extension to compare folders on the remote and the local machine.
