Examples with IBlock org.aion.base.type.IBlock used on opensource projects

Example 1 with IBlock

use of org.aion.base.type.IBlock in project aion by aionnetwork.

the class RecoveryUtils method pruneAndCorrect.

/**
 * Used by the CLI call.
 */
public static void pruneAndCorrect() {
    // ensure mining is disabled
    CfgAion cfg = CfgAion.inst();
    cfg.dbFromXML();
    cfg.getConsensus().setMining(false);
    cfg.getDb().setHeapCacheEnabled(false);
    Map<String, String> cfgLog = new HashMap<>();
    cfgLog.put("DB", "INFO");
    cfgLog.put("GEN", "INFO");
    AionLoggerFactory.init(cfgLog);
    // get the current blockchain
    AionBlockchainImpl blockchain = AionBlockchainImpl.inst();
    IBlockStoreBase store = blockchain.getBlockStore();
    IBlock bestBlock = store.getBestBlock();
    if (bestBlock == null) {
        System.out.println("Empty database. Nothing to do.");
        return;
    }
    // revert to block number and flush changes
    store.pruneAndCorrect();
    store.flush();
    // compact database after the changes were applied
    blockchain.getRepository().compact();
    blockchain.getRepository().close();
}

Example 2 with IBlock

use of org.aion.base.type.IBlock in project aion by aionnetwork.

the class RecoveryUtils method revertTo.

/**
 * Used by internal world state recovery method.
 */
public static Status revertTo(AionBlockchainImpl blockchain, long nbBlock) {
    IBlockStoreBase store = blockchain.getBlockStore();
    IBlock bestBlock = store.getBestBlock();
    if (bestBlock == null) {
        System.out.println("Empty database. Nothing to do.");
        return Status.ILLEGAL_ARGUMENT;
    }
    long nbBestBlock = bestBlock.getNumber();
    System.out.println("Attempting to revert best block from " + nbBestBlock + " to " + nbBlock + " ...");
    // exit with warning if the given block is larger or negative
    if (nbBlock < 0) {
        System.out.println("Negative values <" + nbBlock + "> cannot be interpreted as block numbers. Nothing to do.");
        return Status.ILLEGAL_ARGUMENT;
    }
    if (nbBestBlock == 0) {
        System.out.println("Only genesis block in database. Nothing to do.");
        return Status.ILLEGAL_ARGUMENT;
    }
    if (nbBlock == nbBestBlock) {
        System.out.println("The block " + nbBlock + " is the current best block stored in the database. Nothing to do.");
        return Status.ILLEGAL_ARGUMENT;
    }
    if (nbBlock > nbBestBlock) {
        System.out.println("The block #" + nbBlock + " is greater than the current best block #" + nbBestBlock + " stored in the database. " + "Cannot move to that block without synchronizing with peers. Start Aion instance to sync.");
        return Status.ILLEGAL_ARGUMENT;
    }
    // revert to block number and flush changes
    store.revert(nbBlock);
    store.flush();
    nbBestBlock = store.getBestBlock().getNumber();
    // ok if we managed to get down to the expected block
    return (nbBestBlock == nbBlock) ? Status.SUCCESS : Status.FAILURE;
