Instance Method Details

#install_all_pod_targets(projects_by_pod_targets) ⇒ Hash{String => TargetInstallationResult}

并行安装所有 pod target

原实现（串行）:

projects_by_pod_targets.each_with_object({}) { |(p, pts), r| r.merge!(install_pod_targets(p, pts)) }

优化后（并行）:

使用 Concurrent::FixedThreadPool，每个 project 分配一个线程
并发调用 install_pod_targets，结果通过 Mutex 合并到 all_results

Parameters:

  • projects_by_pod_targets (Hash{Project => Array<PodTarget>}) —

    项目到 pod target 列表的映射

Returns:

  • (Hash{String => TargetInstallationResult}) —

    pod target 名称到安装结果的映射
