Renaming will fail under certain circumstances

[luo2430]

Steps to reproduce

1. Create a new folder and open it with vscode
2. Create a new file 'a.h' and type in

extern int a;

3. Create a new file 'a.cpp' and type in

#include "a.h"

int a;

4. Use a tool (such as cmake) to generate the 'compile_commands.json' file
5. Execute 'clangd: Restart language server'
6. Open 'a.h' and then open 'a.cpp' (It's the same in reverse order)
7. Rename 'int a' and then it will be failed. (If you preview the rename, you will notice that the same place in a file has been modified twice. This problem also occurs when renaming function names or class names)
   

Description

This issue seems to have come up a long time ago, not a recent update. When renaming failed in the past I always thought it was because the extension wasn't powerful enough until one time I previewed renaming.
I came up with a temporary solution by adding the following code inside the {} of 'middleware' in the 'clangd-context.ts' file.

provideRenameEdits: async (document, position, newName, token, next) => {
  let edits = await next(document, position, newName, token);
  // Since edits doesn't provide a member function to modify it, I had to create a new variable
  let new_edits = new vscode.WorkspaceEdit;
  edits?.entries().map(entry => {
    /* For performance reasons, since the same place is renamed twice,
        the operation is performed only if the number of modifications is even */
    if (entry[1].length % 2 == 0) {
      /* When the file has problems renaming symbols, the modifications are
          listed as "change1, change2, change3, change1, change2, change3". 
          So as long as "entry[1][0].range.isEqual(entry[1][index].range" is true, 
          that means there was a renaming error */
      const index = entry[1].length / 2;
      if (entry[1][0].range.isEqual(entry[1][index].range)) {
        entry[1].splice(index);
      }
    }
    // Insert elements
    new_edits.set(entry[0], entry[1]);
  });
  return new_edits;
}

System information

clangd version: 18.1.7 (git://code.qt.io/clang/llvm-project.git 393c912b8e044eb2a86dd9336f4915525bbc051c)
                Features: windows
                Platform: x86_64-w64-windows-gnu
clangd extension version: v0.1.29
Operating system: Windows 11

I'm not able to reproduce this. I'm testing with clangd 18, but on Linux rather than Windows.

In the log, I can see that the duplicate edits appear under two different files which differ only by case.

One is file:///C:/Users/24306/Desktop/abcd/main.h, and the other is file:///c:/Users/24306/Desktop/abcd/main.h. Note the driver letter is uppercase in the first one and lowercase in the second one.

So I think this is some sort of Windows-specific issue related to case-insensitive file systems.

@HighCommander4
Thanks for your reply. My temporary solution may be a little arbitrary, but it does work. Since it won't happen in linux, we can add if(process.platform == 'win32') for it. So will this problem be fixed?

[HighCommander4]

I think a proper fix to this is likely to be on the server side, something like clangd/clangd#108.

That said, the issue may be avoidable with proper configuration. If you share a complete log (starting from clangd startup) that might contain some clues.

@HighCommander4
Well, then I'll just have to package my own extensions to solve this problem. It turns out that this problem has been around for a long time, but it still hasn't been solved, and I don't think it ever will be. I don't know how Jetbrains and QtCreator deal with this problem.

To elaborate a bit on what I mean by this: sometimes, the problem stems from an inconsistency in the compile_commands.json file, e.g. the value of the "file" key has C: in uppercase, but one of the -I flags has c: in lowercase, and resolving the inconsistency avoids the problem.

@HighCommander4
I checked the compile_commands.json built by cmake, it seems that there's no such inconsistency in it.

What I'm seeing in the log, is that vscode is sending a lowercase c: in the path in the textDocument/didOpen command. But the compile_commands.json file uses uppercase C:.

Since you probably can't control what vscode sends, I would try changing the compile_commands.json to contain lowercase c:'s instead.

@HighCommander4
I have a try, it does work, but whenever I use cmake to build a project, it will refresh the compile_commands.json. So maybe it's not the best solution.

[samuelyhsu]

I encountered the exact same problem. Could you please share how you ultimately resolved it? Thank you very much.

@samuelyhsu
My temporary solution is at the beginning of this issue, but you need to be able to package vscode plugins.

[PjgZSK]

I'm not able to reproduce this. I'm testing with clangd 18, but on Linux rather than Windows.

In the log, I can see that the duplicate edits appear under two different files which differ only by case.

One is file:///C:/Users/24306/Desktop/abcd/main.h, and the other is file:///c:/Users/24306/Desktop/abcd/main.h. Note the driver letter is uppercase in the first one and lowercase in the second one.

So I think this is some sort of Windows-specific issue related to case-insensitive file systems.

I encountered this problem on Windows 10, and fix it by change all 'E:' into 'e:' in compile_commands.json generated by cmake(E: is the location of my project).
I use ninja and cmake to build my c++ project.

my reproduce:

1. create Test.h and Test.cpp file.
2. build with cmake
3. restart clangd language server
4. keep them opened in vscode.
5. switch to Test.h.
6. rename a variable in Test.h.
7. and then rename any variable in Test.h will trigger this problem.
