BigInt64Array getting corrupted after an update

[michaelwallabi]

Repro:

• Create a table that contains a BigInt64Array nested within another object
• Store a record
• Update a field in the record

Expected:

• only the updated field has changed

Actual:

• The BigInt64Array is converted to an object after the update. It goes from BigInt64Array[1n,2n] to { 0: 1n, 1: 2n }.

Sample code

const db = new Dexie("usingbigint");
db.version(1).stores({
  obj: 'id',
});

Promise.resolve().then(async ()=>{
  await db.obj.put({id: 1, updated: Date.now(), cols: [{values: new BigInt64Array([1n,2n])}]});
  console.log((await db.obj.get(1)));
  await db.obj.update(1, {
    updated: Date.now()
  });
  console.log((await db.obj.get(1)));
}).catch(console.error);

Are you using dexie3 or 4? I can't open the jsitor link.

Thanks for taking a look @dfahlander. I'm using 3.2.4. Here's a jsfiddle with the repro as well:

Thanks a lot!

@dfahlander I saw you fixed/merged this into the 4.x code line, thank you! Any chance you're going to release a 3.x version with this change?

Thanks @dfahlander. Testing with 3.2.5 and all looks good to me.
