Instance Method Details

#initialize(sandbox, projects, pod_target_installation_results, installation_options) ⇒ Object

初始化：调用原始构造器后，计算所有项目的初始 SHA256 摘要

Parameters:

  • sandbox (Sandbox)
  • projects (Array<Project>) —

    所有需要管理的 Xcodeproj 项目

  • pod_target_installation_results (Hash) —

    pod target 安装结果

  • installation_options (InstallationOptions)

def initialize(sandbox, projects, pod_target_installation_results, installation_options)
  super
  @project_digests = {}    # project.object_id => SHA256 摘要
  @sort_needed = {}        # project.object_id => 是否需要排序
  compute_initial_digests
end

#save_projects(projects) ⇒ Object

增量 + 并行保存项目

流程:

1. 过滤: 跳过 pbxproj 内容未变的项目（SHA256 摘要比对）
2. 排序: 对需要保存的项目调用 sort(:groups_position => :below)
3. 保存: 多项目并行写入（每个 xcodeproj 独立目录）

【Bug 修复 L1】只有当 old_digest 和 current_digest 都非 nil 且相等时才跳过。如果任一为 nil（例如文件不可读），一律重新保存以确保项目完整性。

Parameters:

  • projects (Array<Project>) —

    要保存的项目列表

#write! ⇒ Object

并行清理、重建 scheme、然后增量保存所有项目

流程:

1. 并行清理每个项目的空 groups
2. 并行重建 scheme（将 test target 附加到 library target）
3. 执行 post-install hooks（yield）
4. SHA256 增量判断 + 并行保存
