MainApp(73486,0x16e067000) malloc: *** error for object 0x107300012: pointer being freed was not allocated #971
Description
Hi @mrousavy, currently I have to migrate the unencrypted data to new encrypt MMKV and I am facing this crash as title in the first time when I open an app using MMKV v4 from an app version using MMKV v2
Please take a look and help me investigate this. Thanks!
My Device:
Model:iPhone 13 Pro
Orientation:Unknown
RAM free: 145.45 MB
Operating System
Version:16.5.0
Orientation:Portrait
Jailbroken: No
Env:
"react-native": "0.78.3",
newArch: false,
// old mmkv
"react-native-mmkv": "2.12.2",
// new mmkv
"react-native-mmkv": "4.1.0",
"react-native-nitro-modules": "0.31.10",
This is my code:
import Keys from 'react-native-keys';
import { createMMKV, deleteMMKV, MMKV } from 'react-native-mmkv';
class Storage {
localInstance: MMKV = createMMKV({ id: STORAGE_NAME });
newLocalInstance: MMKV = createMMKV({
id: NEW_STORAGE_NAME,
encryptionKey: Keys.secureFor('STORAGE_ENCRYPTION_KEY'),
});
memory: Record<string, any> = {};
migrateData = () => {
try {
// all data were be migrated
if (this.localInstance.getAllKeys().length === 0) {
return;
}
// all data are migrating...
this.newLocalInstance.importAllFrom(this.localInstance);
// migration is finish
this.localInstance.clearAll();
this.localInstance.trim();
deleteMMKV(this.localInstance.id);
} catch (error) {
if (__DEV__) {
console.log('STORAGE: migration failed: ', error);
}
}
};
constructor() {
this.migrateData();
}
}
const instance = new Storage();
export { instance as Storage };
