> Incorrect use of APP_FETCH_SIZE in GFSH
> ---------------------------------------
>
> Key: GEODE-744
> URL: https://issues.apache.org/jira/browse/GEODE-744
> Project: Geode
> Issue Type: Bug
> Components: gfsh
> Reporter: Jens Deppe
> Assignee: Kevin Duling
> Fix For: 1.0.0-incubating.M3
>
> Attachments: workspace (1).zip

> A customer is facing an easily reproducible issue when executing queries from
> GFSH. It appears that the APP_FETCH_SIZE is being set only when parts of the
> query are in lower case. It happens in 7.0.X, 8.0.X and 8.1.X.
> Attached to the TRAC is the reproducible scenario, steps to reproduce:
> Uncompress the file.
> Modify variables "GEMFIRE" and "JAVA_HOME" in file setenv.txt.
> Execute "./start_cluster.sh".
> Exceute "./run.sh". This script inserts 1500 entries in the region and,
> afterwards, executes two queries, one using lower case and other using upper
> case. You can see from the console that ouput is different, one returns the
> actual size (1500) and the other one returns the default APP_FETCH_SIZE
> (1000).
> Exceute "./stop_cluster.sh".
> The fix seems pretty easy to implement, the method "addLimit" of the inner
> class "SelectExecStep?" in "DataCommandFunction?" class should be modified to
> compare strings without using the actual word case. Is not enough to add more
> "or" to the comparison like we are currently doing with since keywords like
> "Count" or "coUn" will still break the functionallity. We should compare
> everything using lower case or upper case, it doesn't matter which one, or at
> least make sure that gfsh converts the query to upper/lower case before
> actually executing them.
> The actual code with the problem is below:
> {noformat}
> private String addLimit(String query) {
> boolean containsLimitOrAggregate = query.contains(" limit")
> query.contains(" LIMIT") query.contains("count(*)");
> if (!containsLimitOrAggregate){
> String limitQuery = query + " limit " + getFetchSize();
> return limitQuery;
> } else {
> return query;
> }
> }
> {noformat}
