Examples with MutableRepository org.ethereum.db.MutableRepository used on opensource projects

Example 1 with MutableRepository

use of org.ethereum.db.MutableRepository in project rskj by rsksmart.

the class RepositoryTest method setUp.

@Before
public void setUp() {
    trieStore = new TrieStoreImpl(new HashMapDB());
    mutableTrie = new MutableTrieImpl(trieStore, new Trie(trieStore));
    repository = new MutableRepository(mutableTrie);
}

Example 2 with MutableRepository

use of org.ethereum.db.MutableRepository in project rskj by rsksmart.

the class RepositoryTest method testCode.

@Test
public void testCode() {
    Repository track = repository.startTracking();
    byte[] codeLongerThan32bytes = "this-is-code-because-I-say-it-man".getBytes();
    assertTrue(codeLongerThan32bytes.length > 32);
    track.saveCode(COW, codeLongerThan32bytes);
    byte[] returnedCode = track.getCode(COW);
    assertArrayEquals(codeLongerThan32bytes, returnedCode);
    track.commit();
    // Now try to get the size
    int codeSize = repository.getCodeLength(COW);
    assertEquals(codeLongerThan32bytes.length, codeSize);
    byte[] returnedCode2 = repository.getCode(COW);
    assertArrayEquals(codeLongerThan32bytes, returnedCode2);
    repository.save();
    byte[] prevRoot = repository.getRoot();
    // Use the same store
    // Now we'll create a new repository based on the same store and force
    // this new repository to read all nodes from the store. The results must
    // be the same: lazy evaluation of the value must work.
    Repository repository2 = new MutableRepository(trieStore, trieStore.retrieve(prevRoot).get());
    // Now try to get the size
    codeSize = repository2.getCodeLength(COW);
    assertEquals(codeLongerThan32bytes.length, codeSize);
