Subject [jira] [Created] (CASSANDRA-4744) Non-escaped single quotes causes CQL to hang
Date Tue, 02 Oct 2012 01:25:09 GMT
Jason Wellonen created CASSANDRA-4744:
-----------------------------------------

             Summary: Non-escaped single quotes causes CQL to hang
                 Key: CASSANDRA-4744
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4744
             Project: Cassandra
          Issue Type: Improvement
         Environment: Cassandra 1.1.5, RHEL 6.3 x86_64
            Reporter: Jason Wellonen


Single quotes in string literals cause CQL to wait indefinitely.  This behavior is inherited
by clients implementing execute_cql.  The end result is a client application that stops responding.

For example, the following is entered in cqlsh (notice the ellipses):

cqlsh:Keyspace1> INSERT INTO Test1 (testId, test1) VALUES (1566bb5d-9093-4abd-bcaa-e1ac90b94a47,
'This is a test with Cassandra's reserved characters') USING CONSISTENCY LOCAL_QUORUM;
             ... 

This continues until ctrl-c is issued.

I would expect a "Bad Request" message returned immediately, which is the behavior here:

cqlsh:Keyspace1> INSERT INTO Test1 (testId, test1) VALUES (7dcf9529-b57b-4d1d-a396-cff9bc98abb2,
'This is a test without the closing parenthesis in the values section of the insert statement.'
USING CONSISTENCY LOCAL_QUORUM;
Bad Request: line 1:176 missing ')' at 'USING'
