Goals

Trying to initialise the Realm on the app launch

Expected Results

App should be able to initialise the Realm and it should not crash in the Realm.init()

Actual Results

App crashed just after the launch on the Realm.init() method call.

Realm framework version: 5.3.2

Xcode version: 11.6

iOS/OSX version: iOS 13

tgoyne · 2020-07-30T16:15:30Z

Would it be possible to share a Realm file which causes this crash? I'm guessing you can't if it's happening on users' devices, but it'd make finding the exact problem very easy...

jain-mj · 2020-07-31T07:07:08Z

@tgoyne I'm afraid that couldn't be done, app is crashing randomly for some users but for some users it works fine. We had to send another release with the latest version of realm(5.3.2), hoping it would solve the problem, but that too didn't work. We migrated realm framework to 5.2.0 and since then this issue started. Attaching the sample code of Realm initialisation just after the app launch.

`private let realm: Realm

init() {
do {
realm = try Realm(configuration: Realm.Configuration(fileURL: sharedRealmFileURL()))
} catch {
Logger.error(error)
}
}`

In our app we initialise the realm jus after the app launch from the
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool method.

jain-mj · 2020-07-31T07:14:16Z

@tgoyne Unfortunately we are not able to re-produce this at our end in the development phase ...
But its crashing on production for many users we received around 2k affected users warning on the firebase.

qgliu · 2020-08-04T14:33:49Z

We see the same thing in upgrading from 4.XX to 5.3.3.
As of now all users with iOS 13.5.1, iPad7,11 are affected.
It crashes in the start of the app when it try to load Realm with a let realm = try Realm().

leemaguire · 2020-08-11T08:19:35Z

@qgliu Would you be able to share a stack trace & a realm file that is having issues? Thanks

qgliu · 2020-08-11T13:13:47Z

@leemaguire

It crashes in the beginning of the app when we start to setup the Realm configuration and start to load it. It seems crash only on specific iPads and versions. Almost 1/3 of our clients had to reinstall the app.

Known crash iOS version and iPad

iOS: 13.5.1 iPad 7,11
iOS: 13.6.0 iPad (6th generation)
iOS: 13.5.1 iPad Air 2

Code in AppDelegate

extension AppDelegate {
    /// configure realm settings: migration to new version, compact in large data
    func configRealm() {
        let config = Realm.Configuration(
            schemaVersion: 161,
            migrationBlock: { migration, oldSchemaVersion in },
            deleteRealmIfMigrationNeeded: false,
            shouldCompactOnLaunch: { totalBytes, usedBytes in
                let oneHundredMB = 100 * 1024 * 1024
                return (totalBytes > oneHundredMB) && (Double(usedBytes) / Double(totalBytes)) < 0.5
        })
        Realm.Configuration.defaultConfiguration = config
        
        // Now that we've told Realm how to handle the schema change, opening the file
        // will automatically perform the migration
        // we also delete the old orders
        do {
            let realm = try Realm()
        } catch {
            // handle error compacting or opening Realm
            print("failed to load realm with configuration")
        }
    }
}

@qgliu Thanks for sharing! would you be able to send us a Realm file that replicates this? Please send it to [email protected] if you can :)

jedelbo · 2020-08-12T13:21:44Z

We have found at least one possible cause for this. Fix for that is under way.

anhltsefpt · 2020-08-16T18:07:35Z

When the new update is available ? It caused the crash to random users of my app in production. I couldn't procedure this bug on the development environment.

jedelbo · 2020-08-20T14:33:36Z

v5.3.4 contains a fix that might address the issue reported here. As we have only the stacktrace it is not possible to say exactly what the problem is here, but it looks similar to the one we fixed.

sorry that we face the same issue in 5.3.3 and 5.3.4

@seki-ne Could it be that the problem reported here is from a situation where the realm has already been through a failing upgrade with v5.3.3 and thus already in a bad state?

seki-ne · 2020-08-24T14:58:05Z

@jedelbo
i am sorry that i dont know the file is broken or not and we have not update it to v5.3.5 (core 6.0.19)
but v5.3.5 is like to not be stabilize to update
#6699 (comment)

i just want to downgrade to v4.4.1 to avoid crash with our prod app which has large number of users.
but it will crash when downgrade from v5 to v4
is there some safety way to downgrade to v4.4.1?

jedelbo · 2020-09-01T11:24:58Z

@seki-ne I am sorry that the sad news is that if a file has been upgraded to v5, there is not a way to go back. The v4 client would not know how to interpret the v5 file format. However we have make a version that probably could recover a file where the upgrade was aborted in migrate_links. That fix would be available in next release.

This is expected to be resolved in v5.3.6. If not please reopen.

This issue was about a crash while upgrading from one file format version to another. From the description above it looks like you are observing something different. If that is the case, I suggest you open a new issue with relevant information.
