Steps to Reproduce
On app start-up I have a function to retrieve persons HiveObjects that are stored:

final personsBox = await Hive.openBox<Person>('persons');

Error is immediately seen on this line. The app runs a few times without issue, then this popped up suddenly on a subsequent run.

Code sample

Future<void> main() async {
final docDirectory = await getApplicationDocumentsDirectory();
Hive.init(docDirectory.path);
Hive.registerAdapter(PersonAdapter());
}

...

final personsBox = await Hive.openBox<Person>('persons');

Did you find a way to reproduce this error? It would be very helpful...

[seanmc86]

I have been trying to without any luck so far.

I initially thought it had something to do with my app state. Some context on what the app is doing:

1. Hive is responsible for persisting various HiveObjects, including [Persons] and [Messages]
2. My app on first load creates 5 fake [Person] and 10 fake [Message], putting them into [Persons] and [Messages] boxes respectively using auto incrementing keys, via add()
3. After this, every few seconds it creates a new fake [Message] and calls the same add() function to the box
4. If the app is reopened or cold restarted, it will retrieve the existing [Persons] and [Messages] and only repeat step 3 above

On first load this process always works. If I hot or cold restart, kill the app, or send it to background and back to foreground, all of them have the tendency to produce the error on subsequent loads.

I have noticed on some reloads, the debugger catches a "Recovering corrupt box" on the [Persons] box, but then I lose the existing associations between [Persons] and already generated [Messages]. Sometimes it does not display this message though, and simply fails to openBox().

I will keep trying other ways, but any suggestions on testing are appreciated.

[miltoneiji]

Hi, I am also having this bug but I did not find a way to reproduce it in a consistent way too.
By reading the code and trying to understand it, I had some doubts:

1) Sanity-check: the BinaryReaderImpl has a buffer that is basically a list of UInt8, right? Then, in order to read a UInt32, you join 4 of those UInt8, right?
2) So, why that result can not be lesser than 8? Shouldn't it be possible?

same problem
My app creash and restart immediately by android system，then this error occur

[stevenspiel]

I'm on 1.4.1+1 and see that the error comes from lib/src/binary/binary_reader_impl.dart:249

Frame readFrame({HiveCipher cipher, bool lazy = false, int frameOffset}) {
    if (availableBytes < 4) return null;

    var frameLength = readUint32();
    if (frameLength < 8) {
      throw HiveError(
          'This should not happen. Please open an issue on GitHub.');
    }
    if (availableBytes < frameLength - 4) return null;

In my scenario, frameLength is 0. When using a debugger to step into the readUint32() that returns 0, this is the state of things:

While I'm unsure of how to reproduce this, I hope what I provided helps. @leisim Does anything stand out to you?

Is it a problem that _bufferLimit == _offset?

Also, fwiw, _buffer.toString() returns this value:

[stevenspiel]

@leisim Is it safe to say I need to just wait for the Rust implementation?

[stevenspiel]

I think the issue is solved for me after restructuring some of my reading/writing to be synchronous. For me, it was a matter of using Future.forEach over Future.wait so it performs the methods sequentially.

[stevenspiel]

I also needed to delete my old box and start a new one, because I think it was corrupt.

[BasedMusa]

@stevenspiel @leisim I also have this.

[BasedMusa]

After checking the debugger, when it reads my first value via the readDouble method, it first checks if it has the available space needed to do this, using the _requireBytes function. That is where the crash occurs,
The code checks if _offset + bytes is more than the bufferLimit or not. At this point, my bufferLimit was 2693 and my buffer was 2697 and my _offset was 153 and bytes was 8. Hope this helps :)

Also, could you please explain how _offset + bytes or 153 + 8 turned out to be more than 2697?

[BasedMusa]

Update I modified your _requireBytes code to this.

  @pragma('vm:prefer-inline')
  @pragma('dart2js:tryInline')
  void _requireBytes(int bytes) {
    print("OFFSET: $_offset");
    print("BYTES: $bytes");
    print("BUFFER LIMIT: $_bufferLimit");

    print("\n\n$_offset + $bytes > $_bufferLimit IS ${_offset + bytes > _bufferLimit}");
    if (_offset + bytes > _bufferLimit) {
      throw RangeError('Not enough bytes available.');
    }
  }

Here is the last print statement right before it throws the exception:

[mateusfccp]

I am also having this issue and can't find how to fix, also related to frameLength being < 8 (in my case, 0).

[RaviKavaiya]

@leisim @TheMisir any updates on this? I ran into this issue multiple times. But this seems to be arbitrary to me. I couldn't find a reproducible sample code. But AFAIK, this once happened when I tried to open a box and immediately closing it (and around 5-6 times of HOT RESTARTING the app). That corrupted my whole box (also note that I couldn't again reproduce this).

I have fear that whether this would happen in one of my production apps.

You can see that the same issue is mentioned multiple times.

My request is, please take a look at this issue as this seems to be very critical :pray:

Please someone help me solve this issue, Our company app is going to production soon.

Could you share hive code you're using? We don't know exact reason for the issue currently. But if you have the code that reproduces this error it might help us to know what's going wrong. I would check your code in a private session if it would be cool to you, I just want to know what's wrong to solve this issue which is active for months.

After upgrading to flutter 2 this started to happen again. I wasn't using hive_flutter but doing init myself. Turns out I was calling init more than once for the app! Once I moved the hive init to my main to be called once app-wide, that fixed it.

Flutter 2
hive: ^1.6.0-nullsafety.2
