Sylvain Lebresne commented on CASSANDRA-4744:
---------------------------------------------
bq. The problem is, a client that implemented execute_cql cannot recover from
this. My application just pauses indefinitely.
Do you have a precise example? Because I'm not able to reproduce that part (I
get a "Bad Request: line 1:72 mismatched character '<EOF>' expecting '''" right
away, which describe correctly the problem).
To be clear, I'm not contesting that cqlsh does that (have you tried a ctrld-D
to complete the input?).

> --------------------------------------------
>
> 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'
