Tim Armstrong created IMPALA-7833:
-------------------------------------
Summary: Audit and fix other string builtins for long string
handling
Key: IMPALA-7833
URL: https://issues.apache.org/jira/browse/IMPALA-7833
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 3.0, Impala 2.11.0, Impala 3.1.0
Reporter: Tim Armstrong
Following on from IMPALA-7822, there are some other string builtins that seem
to follow the same pattern of having a string size overflow an int passed into
the StringVal constructor. I think in some cases we get lucky and it works out,
but others it seems possible to crash given the right input values.
Here are some examples of cases where we can hit such bugs:
{noformat}
select lpad('foo', 17179869184 , ' ');
select rpad('foo', 17179869184 , ' ');
select space(17179869184 );
{noformat}
