这个 PR 包含两项改动,合在一起只跑一轮 CI。

1. 按三端 release 参数编译共享内核

单测编译共享内核(cpp/patch_core、cpp/update_flow_core)的方式,和任何一个线上产物都不一样:

构建 编译器 标准 RTTI NDEBUG
CI 单测 g++(libstdc++) C++17 开 否
Android clang C++17 关 是
iOS clang C++20(由 RN 决定) 开 是
鸿蒙 clang C++17 开 是

新增 scripts/test-core-platform-flags.sh,用三端各自的 release 参数、在 -Werror 下对每个内核源文件做语法编译,优先使用 clang。test.yml 的 C++ job 会运行它,并且在 podspec 或鸿蒙的 CMakeLists.txt 变化时也会触发。本地可以用 bun run test:core-flags。

当前代码在三组参数下都能干净通过。反向验证过:临时加一处 typeid,Android 这组参数会立即报错。

2. iOS 的 reset 在状态清完后就返回

Android 和鸿蒙的 resetToPackagedBundle 在 reset 状态落盘后就 resolve,删除已下载版本是尽力而为。iOS 却要等删除完成才返回,删除失败时还会报 RESET_FAILED,而它的注释声称「与 Android 一致」,与事实相反。

现在三端统一为:状态清完就算 reset 完成,因为下次启动已经会用回内置包。删除失败留下的目录不再被任何状态引用,之后的常规清理会把它回收。之所以不反过来让 Android 和鸿蒙也等删除完成,是因为它们的删除与下载共用一条串行队列,reset 可能要排在一个在途下载后面,最长约 10 分钟。

RESET_FAILED 现在只表示 reset 状态没能落盘。error_codes.h 和 client 的文档注释已同步更新,purge-restore 测试也按新约定断言。

验证

  • iOS purge-restore 全套通过(带 sanitizer,含负向对照)。
  • 用 Pods 头文件对 RCTPushy.mm 做语法编译,结果干净。
  • bun lint 通过,bun test 441 个用例全部通过。

Summary by CodeRabbit

  • Bug Fixes
    • Resetting to the packaged bundle now completes once the reset state is applied, without waiting for downloaded updates to be deleted. Deletion continues in the background on a best-effort basis, and the currently running version’s files are preserved. If cleanup fails, the reset still succeeds; the issue is logged as a warning rather than reported as a reset failure.
  • Tests
    • Added checks that compile shared core code with platform release flags.

The unit tests build cpp/patch_core and cpp/update_flow_core with the host
c++ (on CI g++/libstdc++), C++17, RTTI and asserts on. No shipped binary is
built that way: Android uses -fno-rtti -fexceptions, iOS compiles with the
C++20 React Native selects, and every release defines NDEBUG. A construct
only one platform rejects first failed in that platform's build.

scripts/test-core-platform-flags.sh syntax-checks every core source with
the three release flag sets under -Werror, preferring clang (the compiler of
every shipped binary). test.yml's C++ job runs it; `bun run test:core-flags`
locally.

📝 Walkthrough

The pull request adds shared-core C++ syntax checks using Android, iOS, and Harmony release flags. It also changes the iOS reset promise to resolve before queued downloaded-version cleanup.

Changes: Core Platform Flag Checks

Layer / File(s) Summary
Platform flag validation
scripts/test-core-platform-flags.sh, package.json, .github/workflows/test.yml
Adds syntax checks for shared-core C++ sources under platform release flags. Adds a package script and runs the checks in the C++ test job. The workflow filter includes the podspec and Harmony CMake file as native-test inputs.

iOS Reset and Cleanup

Layer / File(s) Summary
Reset promise and cleanup behavior
cpp/patch_core/error_codes.h, ios/RCTPushy/RCTPushy.mm, src/clientActivation.ts, scripts/contract.ts, scripts/tests/ios-purge-restore/purge_restore_test.mm
The reset promise resolves after state reset and before queued cleanup. Cleanup preserves the running version’s directory, and failures log a warning instead of rejecting with RESET_FAILED. The error-code comments, API documentation, and tests describe and verify this behavior.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Suggested reviewers: claude

Merge Risk: 🔵 Low · up to f094b

The current reset behavior is consistent with the other platforms, but the iOS test does not firmly protect its resolve-before-cleanup timing. This is a bounded test-confidence gap; follow-up is appropriate, but it does not establish a current reset failure.

Android and HarmonyOS settle the reset promise once the reset state is
persisted and delete the downloaded versions best-effort afterwards; iOS
waited for that cleanup and rejected with RESET_FAILED when it failed (its
comment claimed Android parity). Align iOS with the other two: the reset is
complete once the state is (the next launch resolves to the packaged bundle),
and a directory a failed delete leaves behind is unreferenced, so the regular
cleanup removes it later. Waiting instead would have put Android's and
Harmony's reset behind an in-flight download on their serial queues.

RESET_FAILED now means only that the reset state could not be persisted
(error_codes.h, the client's doc comment); the purge-restore test asserts the
new contract.

Also compile the iOS cores as C++17.

The package supports React Native versions below 0.73, including React Native 0.72. React Native 0.72’s CocoaPods integration selects C++17, and this podspec calls install_modules_dependencies(s). The new check tests iOS only with C++20, so it can accept a C++20-only source change that fails in a supported iOS release build.

Suggested fix

Gate cleanup in ResetOrdering before checking reset resolution.

CleanupOldEntries returns success immediately, so the base implementation can clean up and then resolve the promise while satisfying every current assertion. The test does not detect the changed resolve-before-cleanup behavior.

Add a cleanup gate. Assert resetResolved after cleanup starts but before releasing the gate.

 static BOOL resetResolved;
+static dispatch_semaphore_t cleanupStarted;
+static dispatch_semaphore_t allowCleanup;
 
 Status CleanupOldEntries(const std::string&, const std::vector<std::string>&,

The cleanup stub now fails: the reset promise must still resolve, and the
cleanup must still run. A reset that waited for the delete again rejects
here (checked by restoring the previous behavior: reset_wins fails).
