App crashes on launch (inconsistently) #10393

Closed tsahi-deri closed 1 year ago

tsahi-deri commented 2 years ago

Description

As part of our app launch sequence we use Firestore in order to fetch some app configuration/settings, followed by some other API calls to our backend (fetch user information etc.)

Many times the app crashes instantly after tapping the app icon. While debugging it, some of the crashes just stops on UIApplicaiotnMain(), and others stops on a random Firebase SDK code (see screenshot below) and the thread that crashed is related to Firebase.

Since all the crashes are EXC_BAD_ACCESS, and it inconsistently I suspect it a race data issue. Recently I enabled Thread Sanitizer on Diagnostics settings in order to audit threading issues in the code (see output below).

The issue reproduce using Firebase SDK versions 9.3.0, 9.4.*, 9.5.0, 9.6.0 and 10.0.0.

Exception Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: UNKNOWN_0xD at 0x0000000000000000

Screen Shot 2022-10-23 at 23 53 55

Reproducing the issue

  1. Initialize Firebase SDK
  2. Fetch some document using Firestore SDK right after the first screen appears

10.0.0

Xcode Version

13.3.1

Installation Method

Swift Package Manager

Firebase Product(s)

If using CocoaPods, the project's Podfile.lock

Expand Podfile.lock snippet
```yml Replace this line with the contents of your Podfile.lock! ```

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

dconeybe commented 2 years ago

Thanks for the detailed investigation. The crash could indeed be a symptom of a race condition. I'll take a look this week and let you know what I find.

dconeybe commented 2 years ago

@tsahi-deri Could you test out my fix to see if it fixes the crash for you? Basically, just overwrite credentials_provider.h in your Pods directory with the one from https://github.com/firebase/firebase-ios-sdk/pull/10403 then rebuild and see if the crash goes away.

tsahi-deri commented 1 year ago

@dconeybe Thanks for the quick fix. I will embed you fix as you described and will test it for a couple of days. As I mentioned in the issue description it not reproduce any launch.

tsahi-deri commented 1 year ago

@dconeybe I just want to make sure I did everything correctly. I override the file credentials_provider.h as you mentioned. I'm using SPM, so I update the file under the following path:

Xcode/DerivedData/YSelfie-crdghgncaoomthedvlxwxgadtlzb/SourcePackages/checkouts/firebase-ios-sdk/Firestore/core/src/credentials

Then I rebuild my project only, should I rebuild the Firebase SDK in the path above? If so, can you please instruct me how to do it?

dconeybe commented 1 year ago

Shoot, I don't know about using Swift Package Manager. I only know CocoaPods. You'll have to figure out how to do this with SPM on your own.

What I'm going to do is go ahead and merge the fix in https://github.com/firebase/firebase-ios-sdk/pull/10403. It at least fixes one Thread Sanitizer issue. The fix will then be included in the next release of the SDK. I'm not convinced that this particular race condition is contributing to any crashes though.

You mentioned that "Many times the app crashes instantly after tapping the app icon.". Can you capture some of these crash logs and post them? With specific examples of the crash it may help debug the root cause.

google-oss-bot commented 1 year ago

Hey @tsahi-deri. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

tsahi-deri commented 1 year ago

Hey @dconeybe, after updating to Firebase SDK version 10.2.0 and using the app for a while, I still facing some launch crashes. Below, are some of the crash logs that I captured.

@tsahi-deri The "good" news is that none of those crashes in the updated stack traces appear to be related to Firestore. So perhaps the race condition fix https://github.com/firebase/firebase-ios-sdk/pull/10403 (released in 10.2.0) fixes the initial crash that you reported.

The updated stack traces all seem to be coming from Crashlytics. This could either be a bug in crashlytics or, sometimes, crashlytics is not actually the cause of the crash and its stack traces shadow the original crash. Also, the thread sanitizer output adds a lot of noise.

Could you reproduce the crashes and attach the crash logs with two changes:

  1. Remove Crashlytics - it may be hiding the root cause of the crashes.
  2. Remove thread sanitizer - its output adds a lot of noise
tsahi-deri commented 1 year ago

@dconeybe No problem. By remove Crashlytics, do you mean remove the Crashlytics Run Script that was added to Build Phases, or remove the framework completely? If the latter is true, how do I do it?

dconeybe commented 1 year ago

@tsahi-deri I'm suggesting removing Crashlytics completely from your application. Removing the run script is not sufficient as the run script is only used to capture dSYMs/cSYMs and does not impact the app at runtime. The steps to remove Crashlytics depend on how your app is built (CocoaPods, SPM, framework copied in, etc). I don't have specific guidance on that because I'm not familiar with your application's structure. But I am quite sure that the Crashlytics stack traces are obfuscating the root issue, so it would be very helpful to remove Crashlytics from the equation.
