咱也不懂这是什么。。只是搜com.openai.codex.code_sign_clone 看到了相关问题。 github.com/openai/codex [Bug] macOS app leaves code_sign_clone directories after quit (~965MB per launch) 已打开 06:34PM - 01 Jun 26 UTC yorhasaber bug app ### What version of the Codex App are you using (From “About Codex” dialog)? Co … dex App 26.527.60818 (ChromiumBaseVersion 148.0.7778.179) ### What subscription do you have? Unknown / not relevant to this issue ### What platform is your computer? Darwin 24.6.0 arm64 arm ### What issue are you seeing? Every time I launch and quit the Codex macOS app, a new directory is left under: `/private/var/folders/.../X/com.openai.codex.code_sign_clone/code_sign_clone.*` Each clone is about 965 MB. After launching/quitting Codex multiple times, these directories keep accumulating. On my machine after several app restarts: ```bash clone dirs: 7 6.5G /private/var/folders/.../X/com.openai.codex.code_sign_clone ``` The directories disappear after reboot because macOS cleans the `/var/folders/.../X` temp area. This looks related to Chromium's `MacAppCodeSignClone` / `code_sign_clone` mechanism. Clone creation itself may be expected, but inactive clone dirs are not cleaned up after the app quits. I also observed orphaned helper processes after quitting Codex, including multiple `browser_crashpad_handler` processes and `SkyComputerUseService` processes with PPID=1. ### What steps can reproduce the bug? 1. Launch `/Applications/Codex.app`. 2. Quit Codex.app. 3. Check the clone directory: ```bash find /private/var/folders/*/*/X/com.openai.codex.code_sign_clone -maxdepth 1 -type d -name 'code_sign_clone.*' 2>/dev/null | wc -l du -sh /private/var/folders/*/*/X/com.openai.codex.code_sign_clone 2>/dev/null pgrep -fl 'Codex|node_repl|SkyComputerUse|app-server|browser_crashpad_handler' ``` 4. Repeat launch/quit several times. Observed: each launch creates another `code_sign_clone.*` directory, and old inactive clone dirs remain after quitting. ### What is the expected behavior? After Codex quits, inactive `code_sign_clone.*` directories should be removed by the code-sign-clone cleanup helper. Repeated launch/quit cycles should not keep adding ~965 MB per launch until reboot. ### Additional information I checked that this does not appear to be caused by my Codex `config.toml`. The issue appears to be in the macOS app / Chromium app lifecycle cleanup. The active clone may be held by the running Codex process, but old clone directories were not held by open file handles when checked with `lsof +D`. This suggests cleanup is not being triggered or is not completing for inactive clones. 还有个62GB的 openai/codex/issues/27536 2 个帖子 - 1 位参与者阅读完整话题
