[jira] [Updated] (IMPALA-7833) Audit and fix other string builtins
for long string handling
[ https://issues.apache.org/jira/browse/IMPALA-7833?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Joe McDonnell updated IMPALA-7833:
----------------------------------
Target Version: Impala 4.0 (was: Impala 3.4.0)
> 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 2.11.0, Impala 3.0, Impala 3.1.0
> Reporter: Tim Armstrong
> Priority: Major
> Labels: crash, ramp-up
>
> 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}
