检查自动代码目标 %s 失败: %w
Error message
检查自动代码目标 %s 失败: %w
What it means
Returned when os.Stat on a target fails with an error other than ErrNotExist — i.e. the existence check itself failed. Typical causes are permission denied on a parent directory, ErrPermission, or ErrInvalid paths; ErrNotExist is deliberately tolerated (file is treated as new), everything else aborts. The underlying statErr is wrapped with %w for errors.Is inspection.

Solutions
- Check and fix permissions on every parent directory of the target so the server process can stat the path (chmod a+rx or chown).
- Verify the full target path with `ls -la <dir>` as the same user the server runs as, reproducing the stat failure.
- Shorten the target path if ENAMETOOLONG is the wrapped cause.
- If the file actually should not exist but stat returns an error, remove the problematic symlink or stale mount causing ELOOP/ENXIO.
Example fix
// before drwx------ 10 other dev server/ // server user cannot traverse // after chmod o+rx server/ # or run server as workspace owner # retry the autocode task

return err
} Prevention
- Ensure execute (x) permission on every parent directory of generation targets for the server's user.
- Keep target paths under the project root and reasonably short to avoid ENAMETOOLONG.
- Check mounted volumes are healthy and readable before running generation tasks in CI/containers.
When it happens
Trigger: A path component above the target is not readable/executable by the server process (EACCES on stat); the path is too long (ENAMETOOLONG); the target is on an unavailable mount; circular symlink loops on a path component (ELOOP).
Common situations: Workspace directories owned by another user with restrictive modes; running the service inside a container where repo volumes are mounted root-only; macOS/Linux path-length limits with deeply nested generated files; network filesystems briefly unavailable in CI.
