Raymond Welgosh reassigned CASSANDRA-18526:
-------------------------------------------
Assignee: Raymond Welgosh
> TupleType getString and fromString are not safe with string types
> -----------------------------------------------------------------
>
> Key: CASSANDRA-18526
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18526
> Project: Cassandra
> Issue Type: Bug
> Components: CQL/Interpreter
> Reporter: David Capwell
> Assignee: Raymond Welgosh
> Priority: Normal
> Fix For: 5.x
>
>
> In adding property tests for our type system in CASSANDRA-18504, I found that
> tuples have issues with strings as its escaping doesn’t work in all cases…
> below is a simple example where it fails
> {code}
> package org.apache.cassandra.db.marshal;
> import java.nio.ByteBuffer;
> import java.util.Arrays;
> import java.util.List;
> import java.util.UUID;
> import org.junit.Test;
> import org.apache.cassandra.cql3.FieldIdentifier;
> import org.apache.cassandra.utils.ByteBufferUtil;
> import static org.assertj.core.api.Assertions.assertThat;
> public class UserTypeTest
> {
> @Test
> public void test()
> {
> // tuple parsing checks for : and looks to see if a \\ is before it
> (escaped :), so when the string ends with this escape... we fail to parse
> String str = "thiswillbreakthings\\";
> UUID uuid =
> UUIDType.instance.compose(UUIDType.instance.fromString("00000000-0000-4800-9100-000000000000"));
> List<FieldIdentifier> fieldNames = Arrays.asList(new
> FieldIdentifier(ByteBufferUtil.bytes("a")),
> new
> FieldIdentifier(ByteBufferUtil.bytes("b")));
> List<AbstractType<?>> fieldTypes = Arrays.asList(UTF8Type.instance,
> UUIDType.instance);
> UserType type = new UserType("--dummy--",
> UTF8Type.instance.decompose("name"), fieldNames, fieldTypes, false);
> ByteBuffer original =
> TupleType.buildValue(UTF8Type.instance.decompose(str),
> UUIDType.instance.decompose(uuid));
> String source = type.getString(original);
> ByteBuffer bb = type.fromString(source);
> ByteBuffer[] split = type.split(ByteBufferAccessor.instance, bb);
> assertThat(split).hasSize(2);
> assertThat(split[1]).isEqualTo(uuid);
> }
> }
> {code}
