Let us simply first disable oat hook to debug issues #217 #349 #391.

@JingMatrix
Update to cpp syntax

@JingMatrix
Temporally disable oat hook for debugging
6a21b93 
We need testers to confirm if recent problems of `dex2oat` are caused by the `oat` hook.

Please test CI builds under this working-in-progress pull-requests:

  1. Flash current testing build (debug version): https://github.com/JingMatrix/LSPosed/actions/runs/17439097613 and reboot
  2. Test if De-optimize function in the LSPosed manager context menu is working
  3. No matter if it works, upload the logs generated by the manager after the above test

I was able to successfully re-optimize with this build.

Logs are attached.

@grandpajive Are you sure? From the logs, dex2oat crashes and produces a lot of errors.
Please reboot and redo the experiment.
If possible, please disable all unrelated modules.

You're right.

I rebooted and re-optimized one module. It was successful without the dex2oat errors.
Attaching log.

@grandpajive This time the log is correct. However, you installed the release build from GitHub Actions.
Could you please flash the debug build from GitHub Actions, and redo the test, then upload logs.
Thanks for helping the debugging process.

用了这个版本后，问题似乎得到了解决，现在LSPosed管理器和LuckyTool中都提示可以正常优化dex。然而我在日志中还是发现了一些dex2oat错误。以下是日志：

@44C38B8 Please specify which modules are not working properly, more details are preferred.
Also, it would be helpful to compared with the behavior of dex2oat of LSPosed-IT version. Please flash it, start logging

adb logcat -s Magisk lspd nativeloader AndroidRuntime LSPosed LSPosed-Bridge LSPlant LSPosedContext LSPlt LSPosedService Dobby '*:F' zygiskd64 zygisk-core64 zygisk-ptrace64 zygiskd32 zygisk-core32 zygisk-ptrace32 dex2oat64 dex2oat32 LSPosedDex2Oat > lsposed.log

do your test with modules or the De-optimize context menu, then stop the logcat via Ctrl+C and finally upload lsposed.log.

似乎是对系统app进行hook的模块都不正常，如luckytool和FKcolorOS，对第三方app进行hook的模块正常工作，如哔哩漫游。
我用LSPosed-it在luckytool中执行了一次优化，又在LSPosed管理器中对软件更新进行了一次重新优化。以下是logcat日志
lsposed.log.txt
