[Bug][Android] Accessing data of previously authenticated user results in JNI DETECTED ERROR IN APPLICATION: use of deleted global reference

[solodon4]

[REQUIRED] Please fill in the following fields:

• Pre-built SDK from the website or open-source from this repo: prebuilt
• Firebase C++ SDK version: 8.3.0
• Problematic Firebase Component: Auth
• Other Firebase Components in use: Analytics, Auth, Crashlytics, DynamicLinks, Performance, RemoteConfig, Storage
• Platform you are using the C++ SDK on: Mac
• Platform you are targeting: Android

[REQUIRED] Please describe the issue here:

I am trying to obtain user's profile information right after initializing firebase::Auth as described here:

    // Initialize Firebase Auth
    ::firebase::InitResult auth_res;
    authenticator = ::firebase::auth::Auth::GetAuth(app,&auth_res);
    assert(auth_res == ::firebase::InitResult::kInitResultSuccess);
    assert(authenticator);

    // It's possible for current_user() to be non-null if the previous run left us in a signed-in state.
    if (::firebase::auth::User* user = authenticator->current_user())
        dbg::log(dbg::info, "Auth: current user uid(%s) name(%s) already signed in", user->uid().c_str(), user->display_name().c_str());

Very frequently when the user has been signed in on the previous run, the code crashes in user->uid() above. In this situation, the user would have been authenticated with Play Games sign-in and I have had successfully obtained Firebase Auth token on the previous run.

Here is the relevant stack trace:

It doesn't happen every time in the situation I described, but extremely frequently. Can you confirm whether it is a bug and if so, recommend a workaround before the fix?

Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase C++ quickstarts ?
What's the issue repro rate? (eg 100%, 1/5 etc)

What happened? How can we make the problem occur?
This could be a description, log/console output, etc.

No, you guys don't keep your samples up to date to be built with recent build tools, side-by-side NDK etc. plus they require too much setup.

Hi @solodon4,

Looking at the code, the user_info data is deleted and reconstructed whenever User::provider_data() is called. This would be when the global reference is removed. Is it possible that provider_data() is being invoked on that user in another thread, or other auth operations are occuring on a different thread?

I haven't been able to reproduce this locally. Is there any way you could provide a minimal reproducible test case for this? Thanks!

[solodon4]

Hi @DellaBitta!

I checked my code and the snippet I provided happens right before I register a global AuthStateListener, which happens on the GL thread that cocos2d-x does everything else:

authenticator->AddAuthStateListener(&auth_listener); // register global authentication state change listener

That said, however, I've just hit a similar issue in a different part of code, and it, again, happens on the cocos2d thread inside the state change handler of the above listener:

struct AuthListener : ::firebase::auth::AuthStateListener
{
    void OnAuthStateChanged(::firebase::auth::Auth* auth) override
    {
        assert(auth == authenticator); // Since we only have one in the app and didn't bother to pass it as parameter below
        ::firebase::auth::User* user = auth->current_user();
        others::crash::set_user_id(user ? user->uid() : ""); // <== SIGABRT here in call to uid()
        // ... custom logic
    }
} auth_listener;

The interesting point here is that if you look at the call stack below, you'll see that the state change handler is called right away from the call to register the listener itself. Here is the call stack of thread Thread-35-[GLThread 528] where the SIGABRT appears:

And here is the content of the stack of the very first thread Thread-1-[main]:

firebase::auth::NotifyIdTokenListeners(firebase::auth::AuthData*) 0x000000009e34a3be

which seems weird, as it clearly is related to firebase::auth. Is it possible that this happens due to the global listener and you guys allocating the first thread in the dynamic initializer of that global instance?

Also, based on your questions, are we supposed to make all firebase::auth calls from the main thread only, or are there some precautions we have to make before making them from other threads (like calling JNI AttachCurrentThread/DetachCurrentThread)? I don't remember seeing anything on this in the firebase documentation, so can you elaborate, please?

Thank you!

Hi @solodon4,

I wasn't able to reproduce this locally. I altered the quickstart auth application to sign-in a user only. I then ran it, and quit. Then altered the code to re-use the exisitng user session, added a listenter to output the user's uid() when it's invoked, and also spawned threads to print out the user uid() at "the same time".

As we look into this further, could you try a work around of setting a flag in the callback and use the flag to signal your main game loop thread to perform whatever user operations that you need?
