Replace feature not working (409 conflict)

Checklist

This is a bug report, not a question.
I have searched on the issue tracker for my bug.
I am running the latest FileBrowser version or have an issue updating.

Version

2.63.14

Description

This bug was reported and fixed recently, however I am still running into it.

#5957

After updating, I am still getting the 409 conflict message.

What did you expect to happen?

Duplicate file upload should display the modal with the actions

What actually happened?

It displays the 409 alert.

Reproduction Steps

Upload file with drag and drop
Upload a file with the same name using drag and drop

Files

No response

Hmm, I just tried to reproduce, but I couldn't. Specific OS/browser?

That is very odd.
Running Windows 11, tried in chrome and firefox with the same result.
Tried with txt/jpg/png files.

If it helps, I can create a guest login for the devs to replicate on my server.

It can also be reproduced in the Edge browser of Windows 10.

Perhaps it's a Windows-specific thing, I'm using macOS. Maybe something to do with the filepath separator.

also having the same issue.

running windows 10 with brave. tried testing it on chrome as well, same outcome.

has anyone running on windows NOT run into this issue after updating?

Could you see if this is fixed on Windows with the latest patch version?

I am able to reproduce. I tested various scenarios and it appears to happen if I am replacing a file that has a directory/subdirectory path which contains a space.

For example:

/ - to root (works)
/MyMainDir (works)
/MyMainDir/My SubDir (fails with 409 conflict error)

The URL that appears in the browser (chrome based) is this: https://192.168.59.101/files/MyMainDir/My SubDir/

Where my other rig which is running an older version (v2.63.1), the URL appears as: https://192.168.59.101/files/MyMainDir/My%20SubDir/

Seems to be related to escaping the spaces.

Issue looks fixed for me running 2.63.17

This fix worked for me. Tested it with directories and filenames containing spaces.

1. Update frontend/src/utils/url.ts

Add these helpers after encodePath:

export function decodePath(str: string) {
  return str
    .split("/")
    .map((v) => {
      try {
        return decodeURIComponent(v);
      } catch {
        return v;
      }
    })
    .join("/");
}

export function encodeExistingPath(str: string) {
  return encodePath(decodePath(str));
}

Then update the default export:

export default {
  encodeRFC5987ValueChars,
  removeLastDir,
  encodePath,
  decodePath,
  encodeExistingPath,
};

2. Update frontend/src/utils/upload.ts

Change this:

const normBase = removePrefix(basePath).replace(/\/+$/, "");

to this:

const normBase = url.decodePath(removePrefix(basePath)).replace(/\/+$/, "");

Then change this:

let path = base;

to this:

let path = url.encodeExistingPath(base);

I opened #6040 with a focused fix and regression tests for the remaining encoded-space destination case.
