How frequently does the bug occur?
Sometimes
Description
We have a crash in live app when access to Realm Database in this function:
private func getDatabase() -> Realm? {
return queue.sync {
do {
fixRealmBackgroundCrash(config: appConf)
let db = try Realm(configuration: appConf)
return db
} catch {
logError(err: error)
let databaseConfiguration = Realm.Configuration(
schemaVersion: DatabaseManager.currentSchemaVersion,
migrationBlock: DatabaseManager.migrationBlock
)
fixRealmBackgroundCrash(config: databaseConfiguration)
let db = try? Realm(configuration: databaseConfiguration)
return db
}
}
}
func fixRealmBackgroundCrash(config: Realm.Configuration) {
// Source: https://github.com/realm/realm-cocoa/issues/7112#issuecomment-778218878
let folderPath = config.fileURL!.deletingLastPathComponent().path
do {
let attributes = try FileManager.default.attributesOfItem(atPath: folderPath)
let protectionType = attributes[.protectionKey] as? FileProtectionType
if protectionType != .some(FileProtectionType.none) {
try FileManager.default.setAttributes([.protectionKey: FileProtectionType.none], ofItemAtPath: folderPath)
}
} catch {
log("Unable to set protection attributes for realm folder: \(error)")
}
}

Hi @mmar001, Are you able to reproduce this issue?, this happens all the time or something that happens randomly?, Do you know if this error started in a specific version of realm. This seems related to this https://github.com/realm/realm-swift/issues/6308, but a fix for this issue was merged a long time ago.
This probably been caused by the file permission not been set to none before trying to open the realm.
I'm a little bit confused by the code below, do you have two realm with different configuration? What is the difference between databaseConfiguration and appConfig
appConfig is the configuration of the encrypted DB, if it cannot be opened then it use databaseConfiguration (not encrypted). We cannot reproduce this issue it is reported in crashlytics only on live app.
Hello, we are also seeing a lot of similar crashes on our production apps, the stack traces are not always the same, but they all always end up in terminate function. Do you guys have any hint? In our case these crashes started happening when we updated our RealmSwift from version 3.18 to 10.28.0.
Hi @rserentill do you have any stack traces, terminate function is our internal function when there is an undefined behaviour that we detect in our side, but this could mean many things which could be related to this issue error or not.
Hi @dianaafanador3! Thank you for your answer, yes I do, I'm pasting some of them here. We are accessing Realm from different threads, but all Realm instances are always created and accessed from the same thread.

@rserentill can you open a new issue, the stack traces indicates that the errors are different from the one in this issue. It does seem like this errors may be cause for different reasons. Fill out the form so we can take a closer look into this.
Can you potentially provide the realm file from an affected user? This issue looks so well known to me, it would be great to see if the file is corrupted in similar ways than mine were.
@mmar001 Can you pass the queue you are using to the queue parameter when opening the Realm and let us know if that helps?
