Module: Pod::PodGenerate::Patches::InstallerPatch::ForceIncrementalInstall

Defined in:
lib/cocoapods-podgenerate/patches/installer_patch.rb

Overview

── 优化 1: 强制启用增量安装模式 ──

在 install! 入口处设置 installation_options，强制启用:

- incremental_installation:   只重新生成有变更的 target
- generate_multiple_pod_projects: 每个 pod 独立 xcodeproj

这两个选项是 CocoaPods 内置的（默认关闭），我们通过 monkey-patch 在 super 之前设置，对所有后续流程生效。

#create_and_save_projects(pod_targets_to_generate, aggregate_targets_to_generate, build_configurations, project_object_version) ⇒ Object

── 优化 3+4: 项目生成 + 并行 configure_schemes ──

完全覆盖原 create_and_save_projects 方法，添加并行 configure_schemes。流程:

1. 创建 generator → 调用 generate!（并行安装 pod targets）
2. 设置实例变量（@pods_project 等）
3. UUID 预测 + 稳定化
4. 创建 writer → 并行清理/重建 scheme/保存
5. 并行 configure_schemes（每个 project 独立）

#generate_pods_project ⇒ Object

── 优化 2: 完全无变更时跳过项目生成 + C2/H1 修复 ──

原流程即使没有任何 target 变更，create_and_save_projects 仍会被调用，执行大量 file I/O 操作。本方法在 analyze_project_cache 之后检查:

如果 pod_targets_to_generate 和 aggregate_targets_to_generate
都为空（即没有任何 target 需要重新生成），则:
  1. 跳过 create_and_save_projects（pod 项目已在磁盘上，内容未变）
  2. 仍执行 SandboxDirCleaner（清理可能被移除的 pod 的残留文件）
  3. 仍调用 update_project_cache（保持缓存时间戳最新）
  4. 仍调用 run_podfile_post_install_hooks（Podfile hook 不能跳过）

v0.1.4 修复 (C2):

- 设置 @pods_project = nil, @pod_target_subprojects = [],
  @generated_projects = []（避免下游引用 nil）
- 调用 run_podfile_post_install_hooks（之前被跳过导致 hook 静默丢失）

v0.1.4 修复 (H1):

- 使用上次的 @target_installation_results 更新缓存
  （而非空的 InstallationResults，避免清除 metadata_cache）
