Description

First time seeing such an error. We've just got a crash report from a user that got the realm database in a state that it cannot start by any means, possibly a corrupted file?

In short {{ await Realm.open}} always fails with an exception and it cannot be recovered from. See below for more info.

Can you reproduce a bug?

Not yet

Reproduction Steps

export default async function initDatabase() {
  let res = await Realm.open({
    schema: [
      ...my schemas...
    ],
    schemaVersion: 8,
  });

  return res;
}

Call initDatabase somewhere on app start / root mount, and get the above exception error with the init failure.

Version

10.20.0-beta.4

What SDK flavour are you using?

Local Database only

Are you using encryption?

No, not using encryption

Platform OS and version(s)

iOS 14.7.1 - iPhone 7 plus

The text was updated successfully, but these errors were encountered:

cristianoccazinsp · 2022-04-27T17:11:03Z

Further, the app may have been close to running out of space (~2gb left).

fronck · 2022-04-28T08:46:21Z

@cristianoccazinsp Thanks for reporting this. We will look into the issue. Please let us know is you come upon further information or find a reproduction scenario.

cristianoccazinsp · 2022-04-28T14:38:45Z

In the meantime, what's the best option to handle a scenario like this? What can be done to either the database (discarding corrupted tables)? As it is right now, the app is 100% unable to start until re-installed or if the storage gets wiped by the OS.

cristianoccazinsp · 2022-05-23T15:03:24Z

Has there been any update regarding this? Any discoveries?

kneth · 2022-05-24T08:39:25Z

@cristianoccazinsp

If the Realm file was created using 10.20.0-beta.3 or earlier, the corruption might be carried forward. If it is the case, I suggest that you delete the Realm file. Your issue has some similarities with #4525.

cristianoccazinsp · 2022-07-09T17:20:51Z

The bug report was with 10.20.0-beta.4, so I'm not sure whether or not the user with the issue ever had beta.3.

I haven't seen other uses with this problem so far, but have you guys figured anything else or any work-around in case this ever happens again? Prompting users to re-install an app is really bad. Would an attempt at copy / delete / rename of the realm file recover the corruption or something?

cristianoccazinsp · 2022-08-13T01:22:29Z

@kneth similar user-lock issue but with another crash. We are using 11.0.0-rc.0 and just received this. This user device basically crashes every single time it tries to write an update or insert to the realm database.

This is only a guess, but the schema causing issues is most likely the following. At this point, we are in a situation where the only fix is to have the user re-install and lose all his data.

export const QueueItemSchema = {
  name: 'QueueItem',
  primaryKey: 'id',
  properties: {
    id: 'string', // uuid
    groupId: {type: 'int', indexed: true},
    priority: {type: 'int', indexed: true},
    mobile: {type: 'bool'},
    added: {type: 'int', indexed: true},
    preventsSync: {type: 'bool', indexed: true},
    uploading: 'bool',
    error: 'bool',
    errorInfo: 'string',
    locked: {type: 'bool', default: false},
    lastUpdate: {type: 'int'},
    uploadData: 'string', //json serialized data
    extraUploadData: {type: 'string', optional: true}, // json serialized data
    uri: {type: 'string', optional: true},
  },
};

Further, this started happening after an app update, probably when upgrading realm from a version beta version as well.

And the crash log.

@tomduncalf @takameyer

We continue to see some more crashes related to corrupted databases that pretty much locks the user from using the app until a full reinstall. In addition to the above, here's a new one from today.

These all started right after upgrading to 11.0.0-rc.0 (from 10.20.0-beta.4 or 10.20.0-beta.5). Can we please get some priority review of this? A corruption this bad is really hurting our users and telling them to reinstall is being problematic as they lose important data.

In the interim, any work-around or suggestion would also be greatly appreciated.

tomduncalf · 2022-08-17T16:45:22Z

@cristianoccazinsp We're investigating this – do you have any other stack traces you could share?

cristianoccazinsp · 2022-08-17T17:14:52Z

@tomduncalf for users getting locked with a crash, only the above two traces. We may get more detailed traces once apple sends it to us through XCode.

takameyer · 2022-08-18T09:31:09Z

@cristianoccazinsp We think it's possible this could be happening on migration. Can you provide any details on your migration strategy?

cristianoccazinsp · 2022-08-18T14:28:51Z

Hi @takameyer ,

We haven't done any migration in a long time, besides w/e is done when the library version changes.

This is all the code related to creating/opening the realmdb:

kneth · 2022-08-18T14:55:43Z

@cristianoccazinsp The reason for the question is that the stack trace has realm::Table::remove_search_index(realm::ColKey). Removing is also considered a schema change.

cristianoccazinsp · 2022-08-18T15:08:44Z

That is strange, we haven't touched the schema definition in a long time, certainly didn't remove indexes, but I will do some more digging to see if an index changed at some point without upgrading the schema version. However, wouldn't that always return in a crash?

cristianoccazinsp · 2022-08-19T13:52:19Z

@kneth I can confirm we haven't changed the db schema in the past 10 months, so I'm not sure where's the remove_search_index call coming from. Further, the change that was done 10 months ago was only a new field being added (no indexes).

kneth · 2022-08-19T14:21:04Z

@cristianoccazinsp It is an interesting observation. If possible, we would like to get a copy of the Realm file in order to understand how it can trigger the code path in the stack trace.

cristianoccazinsp · 2022-08-19T14:33:38Z

Hi @kneth , I don't think we have a good way to extract the database of the user having those persistent crashes, he also already re-installed the app as instructed. How else can I help? Would a local copy of a non-crashing db file work?

kneth · 2022-08-22T07:26:01Z

@cristianoccazinsp If you sent us a file, we can run a couple of checks to see if something pops up. Moreover, we can send back what we believe is the schema and you can verify it. Not that I think it will give us much insight into this issue.

cristianoccazinsp · 2022-08-22T15:48:45Z

@kneth I sent you the db file in an email. Let me know if you've got it and if you need anything else.

kneth · 2022-08-23T12:59:26Z

@cristianoccazinsp Thank you. I have examined the file and replied by email.

joze144 · 2022-09-09T07:27:13Z

I've reported a similar issue here: #4891

Was there any resolution with this bug? Would at least like to prevent this from happening in the future.

@kneth let me know if you need any more realm file for debugging purposes

kneth · 2022-09-09T08:42:37Z

@joze144 Please see my comment

kneth · 2022-10-20T11:35:09Z

@joze144 @cristianoccazinsp We have not been able to reproduce the issue. Do you observe the issue recently?

cristianoccazinsp · 2022-10-20T15:06:25Z

@kneth i haven’t seen the issue lately.

kneth · 2022-10-21T13:39:21Z

@cristianoccazinsp That's great news. I'll close the issue, and you are welcome to either create a new or reopen if it occurs again.
