The set filemode is incorrect

Reproduction steps

Azure DevOps

1. Create YAML Pipeline just for monitoring filemode (show all files with filemode, script: git ls-files --stage) and create build validation policy for main branch

2. Create file "test1.sh" in folder "folder1", create PR to main and complete it

3. On new branch make changes, push it, hard reset to previous commit, create "folder2", move "test1.sh" to this folder, change filemode to 100755 (git update-index --chmod=+x file_name), force push, create PR to main and complete it

4. Switch to previous commit (before changing folder and file mode), push any changes, create PR to main and check build validation pipeline logs on the PR

Expected behavior

File mode is 100755 (new)

Actual behavior

File mode is 100644 (old)

Tái hiện kịch bản Azure DevOps bằng git ls-files --stage, việc di chuyển sang folder2 và git update-index --chmod=+x. Sau đó, theo dõi cách LibGit2Sharp xử lý các chế độ tệp trong suốt chuỗi commit và push đã mô tả. Hoàn tất khi pipeline xác thực báo cáo chế độ tệp 100755 thay vì 100644 cho tệp bị ảnh hưởng.
