unable to get processes in older Python versions

frida/core.py の enumerate_processes()、get_process()、attach() から始め、それらの Python 3.6/3.7 での動作を、動作している Python 3.8 のセットアップと比較します。frida-ps -U と報告されたプロセス名を使って不一致を再現します。プロセス検索が期待されるプロセスを返し、同じ実行中のターゲットに対して attach が失敗しなくなれば完了です。

enumerate_processes() / attach / processed that end up calling get_process() fail to get all processes when using python3.6 / 3.7

When i switch to python 3.8.1 and run the same script, it works flawlessly

I ensured the process was actually running via frida-ps -U | grep <myproc> (uses my system default python of 3.8) and verifying with ps -ef via shell and its indeed running

What seems to be happening, is some apps are being returned to Frida's process list with their application name instead of package name for the same pid . example ( instead of com.z.foo , it shows as Foo)

Attempts to connect to Foo instead of com.z.foo fail with

frida.ServerNotRunningError: unable to connect to remote frida-server: Connection closed
