Firebase-ios-sdk: Memory leaks on [FIRClearcutLogger sendNextPendingRequestWithCompletionHandler:]

Created on 24 Oct 2018 · 9Comments · Source: firebase/firebase-ios-sdk

[REQUIRED] Step 2: Describe your environment

Xcode version: 10.0 (10A255)
Firebase SDK version: 5.10.0
Firebase Component: Core
Component version: 5.1.5

[REQUIRED] Step 3: Describe the problem

Lots of memory leaks on [FIRClearcutLogger sendNextPendingRequestWithCompletionHandler:]. Is it possible to apply the same fix as here: https://github.com/firebase/firebase-ios-sdk/issues/1917?

Steps to reproduce:

Happens after calling FirebaseApp.configure()

Here's a typical stack trace:

    0 libsystem_malloc.dylib malloc_zone_realloc
    1 libsystem_malloc.dylib realloc
    2 CoreFoundation __CFSafelyReallocate
    3 Foundation _NSMutableDataGrowBytes
    4 Foundation -[NSConcreteMutableData appendBytes:length:]
    5 GoogleUtilities 0x1036c664f
    6 GoogleUtilities 0x1036c1753
    7 App -[FIRClearcutLogger sendNextPendingRequestWithCompletionHandler:]
    8 App -[FIRClearcutLogger sendLogsWithCompletionHandler:]
    9 libdispatch.dylib _dispatch_call_block_and_release
   10 libdispatch.dylib _dispatch_client_callout
   11 libdispatch.dylib _dispatch_lane_serial_drain$VARIANT$mp
   12 libdispatch.dylib _dispatch_lane_invoke$VARIANT$mp
   13 libdispatch.dylib _dispatch_workloop_worker_thread
   14 libsystem_pthread.dylib _pthread_wqthread
   15 libsystem_pthread.dylib start_wqthread

Get about 100 leaks on each launch.

@agordeev Thanks for the report. What version of GoogleUtilities do you have installed? Version 5.3.4 includes a fix (#1970) for a crash from FIRClearcutLogger (#1964), that could be related.

Also, it seems the two calls to GoogleUtilities are unsymbolicated. Can you get a fully symbolicated stack trace?

GoogleUtilities was updated to the latest (5.3.4) version as well.

How to I do that? That's not the crash log, I was browsing through Xcode's Object graph

I think I'm seeing something similar. I'm using Firebase 5.11 downloaded from firebase.google.com and added to the project manually... so I'm not sure which version of GoogleUtilities is bundled with it, but I assume the latest.

If it helps, my calls to GoogleUtilities are symbolicated:

0 libsystem_malloc.dylib malloc_zone_malloc
1 CoreFoundation _CFRuntimeCreateInstance
2 CoreFoundation __CFStringCreateImmutableFunnel3
3 CoreFoundation CFStringCreateWithBytes
4 Foundation +[NSString stringWithUTF8String:]
5 Foundation -[__NSConcreteUUID UUIDString]
6 CFNetwork -[__NSCFURLSession initWithConfiguration:delegate:delegateQueue:]
7 CFNetwork -[__NSURLSessionLocal initWithConfiguration:delegate:delegateQueue:]
8 CFNetwork +[NSURLSession sessionWithConfiguration:delegate:delegateQueue:]

Thanks @yonomitt, but the latest GoogleUtilities didn't make Firebase 5.11.0 - see https://github.com/firebase/firebase-ios-sdk/releases. It will be in the next zip download release.

@paulb777 I have also same issue with latest pod version.
