Describe the bug

I want to use vscode-extensions.vadimcn.vscode-lldb.adapter (providing codelldb) for it's Debug Adapter support. Particularly it seems like Helix can utilize it with some early debugging support.

However, it doesn't seem to work. After adding that to my nix shell, and entering it, and trying to run it, I get:

[cole@porty:~/code/rust-nix-template]$ codelldb
Error: "\"/nix/store/rnqda0vmhg95ziahvl7r6y10x4xk1y6z-vscode-lldb-adapter-1.6.10/lldb/lib/liblldb.so: cannot open shared object file: No such file or directory\""

I suspect that vscode-lldb's fork of lldb needs to be updated?

Oh yeah, that would be because the adapter is patched-inline in the extension process and the unwrapped, useless, adapter is passed thru instead.

I have some work that fixes this:

  1. codelldb just uses regular lldb now, we can drop the "fork" with the "rust-enabled" check
  2. codelldb tries to exec-itself in certain scenarios and must be patched so that it properly calls its wrapped version

But most of all, it seems like lldb-vscode is ... just built as part of lldb already. I'm not even sure if there's a huge point in bothering with codelldb and vscode-lldb in general.

I really wish this were less messy. codelldb was a hassle to figure out, lldb-vscode has a bad name, the repo that you find online is old and says darwin-only. yeesh.

Actually #236915 only resolves the libcodelldb.so issue. The original issue of missing liblldb.so still exists somewhat. Yet a working codelldb binary can be found after that PR at

$(nix show-derivation github:NixOS/nixpkgs/nixpkgs-unstable#vscode-extensions.vadimcn.vscode-lldb | jq -r '.[].outputs.out.path')/share/vscode/extensions/vadimcn.vscode-lldb/adapter/codelldb

Help is wanted to resolve the path issue of the adapter sub package 🥲

vscode-extensions.vadimcn.vscode-lldb: fix on Darwin
0c110aa 
Summary:

  vscode-lldb has been broken on Darwin due to a build-time issue:

    * on Darwin, the vscode-lldb build scripts expect $HOME to exist and be
      writable, NixOS#202507

  and several runtime-issues:

    * codelldb can't find its dynamic libraries (NixOS#160874)

    * lldb-server from nixpkgs doesn't work due to missing the

        "com.apple.security.cs.debugger"

      macOS codesigning entitlement, (NixOS#38624), also with the symptom that
      tccd, the macOS "Transparency, Consent, and Control" daemon, denies
      requests it receives from vscode/codium with log messages like:

	  "AUTHREQ_CTX: msgID=..., function=<private>, service=kTCCServiceDeveloperTool, preflight=yes, query=1,"
          "Service kTCCServiceDeveloperTool does not allow prompting; returning denied."
          "AUTHREQ_RESULT: msgID=..., authValue=0, authReason=5, authVersion=1, error=(null),", etc.

    * lldb-server from nixpkgs may also provide a different CLI interface than
      codelldb expects on macOS.

    * vscode-lldb directs lldb to load rust pretty-printing scripts which need
      to be preserved through the build process in nixpkgs

Solution:

  * The build problem can be fixed by setting HOME="$(pwd)/home", as suggested
    in NixOS#202507.

  * The dynamic libraries issue can be fixed by setting LD_LIBRARY_PATH while
    wrapping codelldb

  * The permissions issue and CLI interface issue can both be fixed by using
    Xcode's debugserver,

      /Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework/Versions/A/Resources/debugserver

    on macOS, since it has the required entitlement and the expected interface.

  * Finally, the script-loading issue can be fixed by copying the required
    scripts to the location that vscode-lldb expects to find them in.

Fixes:

  * NixOS#148946: Error failed to get reply to handshake packet on x86_64-darwin
    with vscode-extensions.vadimcn.vscode-lldb

  * NixOS#160874: codelldb inside of vscode-lldb extension doesn't work

  * NixOS#202507: vscode-extensions.vadimcn.vscode-lldb fails to build on aarch64-darwin

@colemickens why was this closed? I don't think it's fixed.
