Protobuf crash on 32-bit devices in PHTFlatFilePhenotype and Firestore (leveldb)

[fangyuxi]

I'm using firebase 6.8.1 When new App is released at Appstore, I found more crashs appear in firebase dashboard. I do not use ProtoBuf directly I updated all Pods, before upload package to Appstore. All componets are newest.

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

[paulb777]

Please share the Podfile and Podfile.lock. Also, any other patterns in where the crashes occur like iOS versions, etc.

[neilmorton]

I am seeing the same crash on 2 apps.

@paulb777 The crashes I am seeing appear to be from iOS 9 and iOS 10 only on both apps. Also, these builds were compiled with the Xcode 11 GM Seed.

@fangyuxi what version of Xcode did you compile the build with? (Just wondering if other users haven’t spotted this yet, or if it is an issue compiling against the Xcode 11 GM seed?)

[fangyuxi]

@neilmorton The Xcode version is 10.3. Not Xcode 11 GM. Now, this problem has caused a lot of Crash. (Just wondering if other users haven’t spotted this yet)

@paulb777 The specific compilation environment and podfile or podfile lock will be available to you tomorrow.

[neilmorton]

@fangyuxi That’s interesting about the Xcode version. Can you see what versions of iOS are affected for you? Are you seeing it limited to iOS 9 and 10?

[fangyuxi]

@neilmorton Yes iOS 9 and iOS 10 Only

[fangyuxi]

@neilmorton Now I am concerned about whether this Crash will cause iOS 9 and iOS 10 users to not use the App properly(I don't have an iPhone for iOS9 or iOS 10 to test.). If the user only occasionally encounters this Crash, then we still have time to fix it.

[neilmorton]

@fangyuxi ok. I was limiting Firebase to 6.5.0 before my latest build due to a previous issue. I thought that was fixed, but seems there is now a new issue. I am going to limit the pod file back to 6.5.0 and resubmit whilst this gets figured out.

[neilmorton]

@fangyuxi Looking at the data in Fabric I am sufficiently concerned by the number of iOS 9 / 10 users affected that I am reverting to the Firebase build that I had limited to due to the past issues.

Podfile update: pod 'Firebase/Core', '~> 6.5.0'

[fangyuxi]

@neilmorton Please check to see if these versions are stable? Thank you very much !

@fangyuxi I am not sure what you want me to check, but what I can say is that the current config (with the issue) is:

Installing Firebase 6.8.1 (was 6.5.0)
Installing FirebaseABTesting 3.1.1 (was 3.1.0)
Installing FirebaseAnalytics 6.1.1 (was 6.0.4)

Using nanopb (0.3.901)

I have now locked Firebase back to 6.5.0 (reverted to what I was running previously):

Removing FirebaseCoreDiagnostics
Removing FirebaseCoreDiagnosticsInterop
Removing GoogleDataTransport
Removing GoogleDataTransportCCTSupport

I have done this as there wasn't an issue previously and I want the iOS 9 and iOS 10 users back up and running.

Looking at your information, it seems that you have Installing FirebaseCore (6.1.0) shown.

Have you added the pod 'Firebase/Core', '~> 6.5.0' to your Podfile instead of the default and run pod update to get to this config? If so, then looking at the associated versions, then this looks to match with mine.

I hope this helps.

[fangyuxi]

@neilmorton OK Thank you.

[paulb777]

I believe that the backtrace shown would only come from FirebasePerformance. Would you confirm if removing FirebasePerformance makes the crash stop occurring?

[fangyuxi]

@paulb777

It seems that this Crash only come from FirebasePerformance, but now I am ready to roll back the version to 6.7.0. Because there are too many users showing this Crash.I guess that after removing FirebasePerformance, the Crash should not appear, but updating the app version takes time, affects many users, so dare not try to remove FirebasePerformance.

Thank you.

Also, if this is configured(pod 'Firebase/Core', '~> 6.7.0'), will all the dependent Pods roll back to 6.7.0?

[neilmorton]

@neilmorton OK Thank you.

You are welcome @fangyuxi

[neilmorton]

I believe that the backtrace shown would only come from FirebasePerformance. Would you confirm if removing FirebasePerformance makes the crash stop occurring?

@paulb777 Unfortunately I am in the same position as @fangyuxi. I had issues after moving up past 6.5.0 previously in that I was seeing a raft of GDTUploadCoordinator.m crashes. At that point there was a comment from yourself that suggested reverting to 6.5.0 https://github.com/firebase/firebase-ios-sdk/issues/3547#issuecomment-520151994.

I had just made the decision to lift that version hold with this latest release to now experience this new issue across 4 apps with the latest builds ready for iOS 13.

I don't really want to risk just removing FirebasePerformance in case there is still an issue.

Rather I have, as mentioned above, locked them all back to 6.5.0. In the meantime I shall consider the options!

[neilmorton]

Also, if this is configured(pod 'Firebase/Core', '~> 6.7.0'), will all the dependent Pods roll back to 6.7.0?

@fangyuxi If you run pod update after making the change in the Podfile, then it should manage the dependencies, yes.

[paulb777]

If you run pod install, versions of existing pods won't necessarily change.

if you run pod update, versions will update to the latest unless there are version specifications in the Podfile.

pod 'Firebase/Core', '~> 6.7.0' indicates to use the latest Firebase pod at version 6.7.*. The Firebase pod specifies that its dependencies can do patch updates.

Thus if you do a pod update with pod 'Firebase/Core', '~> 6.7.0' you will get `FirebasePerformance 3.1.4 even though 6.7.0 released with 3.1.3.

@fangyuxi It looks like you still have 3.1.2. Please confirm the issue is still occurring with 3.1.4.

Same issue here :'(

iOS 10 only, Firebase dependencies:

pod 'Firebase/Core', '= 6.8.1'
pod 'Firebase/Analytics', '= 6.8.1'
pod 'Firebase/Performance', '= 6.8.1'

[neilmorton]

@bill350 Is your lowest platform supported iOS 10?

[bill350]

@bill350 Is your lowest platform supported iOS 10?

Yes, iOS 10 -> iOS 13

[paulb777]

Thanks for the additional data about iOS versions.

It seems that this is an issue for iOS 9 and iOS 10. Maybe also iOS 8?

[neilmorton]

My lowest supported build is iOS 9, and iOS 9 and 10 are affected for me. As you say, it could be for 8 too, but I can’t say, sorry.

[patrickmarshall]

Hello, We are also got same issue here. We haven't change firebase version since 3 months ago and the problem just start occurred since September 13th. Is it possible that the problem is from BE side?

pod 'Firebase/Core', '= 6.2.0'
pod 'Firebase/Analytics', '= 6.2.0'
pod 'Firebase/Performance', '= 6.2.0'

My lowest platform support is iOS 10.

@paulb777

[andrew-muzz]

Hello, Same issue here but ours is also impacting iOS 11 and 12. Having said that it's massively skewed towards iOS 10 (67%), not sure about iOS 9.x (we only support 10.2 and above). Looking at the device range affected it's 70% iPhone 5 series. These are always aligned so hard to tell if it's the device or the OS making it more likely to happen.

It only started occurring for us when we released custom tracing for the first time on 14th September. It hasn't happened for any other versions, this would seem to indicate something wrong with custom performance tracing. The following are the Firebase versions we're using:

    pod 'Firebase/Analytics', '~> 6.2.0'
    pod 'Firebase/Core', '~> 6.2.0'
    pod 'Firebase/Performance', '~> 6.2.0'
    pod 'Firebase/RemoteConfig', '~> 6.2.0'

We're going to remove custom tracing until we can figure out what this issue is.

Hi @patrickmarshall

Can you share your Podfile and Podfile.lock?

[Strate]

Maybe related. More crashes started with our new release, ios 10 & ios 9 only:

Hi I have same issues with this , and its crash only for iOS 10 iPhone 5 @paulb777

[visumickey]

@Strate That crash messaged by you does not seem to be related to the current issue. Thanks for bring this to attention though. Can you create a separate issue to track that thread?

The recent changes to Firebase Performance SDK is not related to the stack trace shown. Seem to be a dependency issue. I will keep the group posted on the findings. We are working to make sure we crack this out soon.

[visumickey]

Has anyone been able to reproduce this issue locally? Curious to know if there are any log messages that happened around the crashing time?

[fangyuxi]

@visumickey

I have rolled back to version 6.7.0, but this Crash still appears. Below is the details.

Googlers-only: Related to go/phenotype-deadlock

[Strate]

@visumickey I see same frames on the right side of stacktrace, but okay

[ChristianVinterly]

Same issue here on iOS 10 (lowest supported). Xcode 11 GM.

[ashokbhakharios]

Same issue here but also impacting iOS 11 and 12 users.

Firebase SDK- '6.7.0'

[ChristianVinterly]

[ChristianVinterly]

Using Firebase (6.7.0)
Using FirebaseABTesting (3.1.0)
Using FirebaseAnalytics (6.1.1)
Using FirebaseAnalyticsInterop (1.4.0)
Using FirebaseAuth (6.2.3)
Using FirebaseAuthInterop (1.0.0)
Using FirebaseCore (6.2.1)
Using FirebaseCoreDiagnostics (1.0.1)
Using FirebaseCoreDiagnosticsInterop (1.0.0)
Using FirebaseFirestore (1.4.5)
Using FirebaseInstanceID (4.2.3)
Using FirebasePerformance (3.1.2)
Using FirebaseRemoteConfig (4.3.0)
Using FirebaseStorage (3.4.0)

[ChristianVinterly]

If this crash is suddenly happening on versions 6.2.0 - 6.8.1, on Xcode 10 and 11 GM, and for people that haven't changed firebase version for 3 months, then it sounds like a BE issue like @patrickmarshall suggests?

[neilmorton]

Looking at the results from my updates to lock back to pod 'Firebase/Core', '~> 6.5.0' as mentioned early in this thread (which only went live last night to 3 apps), I can see that (in 1 app at least), the issue is still there now I reverted to the previous version.

Further, I now see that I have a previous build that was updated around 1 month ago has now got 1 single instance of this issue that is reporting as Sep 08 2019 08:06 (UTC) (iPhone 4s iOS 9.3.5).

As @ChristianVinterly & @patrickmarshall suggest, is this a backend change that has caused this?

All crashes I am seeing have been limited to iOS 9 / 10.

[ashokbhakharios]

Looks like most of the crashes are on jailbroken devices though crashlytics dashboard shows 0% jailbroken devices but while checking individual crash details, All devices are shown jailbroken devices.

[neilmorton]

I just looked at my stats and, unlike @ashokbhakharios mine are not showing as Jailbroken (either at the dashboard or individually). All are showing Jailbroken: No. So I guess that may not be linked.

[ChristianVinterly]

Mine are also not Jailbroken

[Strate]

@ChristianVinterly is your crashes caused by updating pod versions? Or it just begin crash without your actions?

[bill350]

To add some information:

As suggested in my previous comment, it happens only on iOS 10 (min iOS 10 to iOS 13) and our last app version (1.6) :

We update Firebase regularly and we upgrade Firebase Core, Analytics and Performance from 6.7.0 to 6.9.1.

App shipped with Xcode 11 GM (not the GM 2).

[ChristianVinterly]

In our app, the crashes appeared yesterday after we released an update to TestFlight from Xcode 11 GM. The update did not change the Firebase SDKs, and the crash has not appeared on other versions of the app.

[paulb777]

Wondering if this is a build tools issue - stemming from building with Xcode 11 instead of Xcode 10. Has anyone seen the issue with an Xcode 10 build?

[ChristianVinterly]

I think the original post used Xcode Version 10.2.1.

[neilmorton]

My latest builds are with Xcode 11 Seed. But the one I have seen spring up from a build created 1 month ago was not the latest, so was 10.x
