Calling drop crashes app (persistentstorecoordinator sqlite error code:522 'not an error')

[denrase]

Hey,

we got an error when calling drop and then trying to use the stack again. This is due to the fact that the wal and shm file are not deleted (http://stackoverflow.com/questions/18277092/persistentstorecoordinator-sqlite-error-code522-not-an-error). We have implemented a workaround in a subclass for now which fixes the issue.

- (void)drop {
    NSPersistentStore *store = [self.mainContext.persistentStoreCoordinator.persistentStores lastObject];

    NSString *sqliteFile = store.URL.path;
    sqliteFile = [sqliteFile stringByDeletingPathExtension];

    NSString *shm = [NSString stringWithFormat:@"%@.sqlite-shm", sqliteFile];
    NSString *wal = [NSString stringWithFormat:@"%@.sqlite-wal", sqliteFile];

    NSFileManager *fileManager = [NSFileManager defaultManager];

    NSError *error = nil;
    if ([fileManager fileExistsAtPath:shm]) {
        [fileManager removeItemAtURL:[NSURL fileURLWithPath:shm] error:&error];
    }
    if ([fileManager fileExistsAtPath:wal]) {
        [fileManager removeItemAtURL:[NSURL fileURLWithPath:wal] error:&error];
    }

    if (error) {
        NSLog(@"ERROR Could not delete persitent store sql or wal file: %@", error.localizedDescription);
    }

    [super drop];
}
