[SPARK-23986][SQL] freshName can generate non-unique names ## What changes were proposed in this pull request? We are using `CodegenContext.freshName` to get a unique name for any new variable we are adding. Unfortunately, this method currently fails to create a unique name when we request more than one instance of variables with starting name `name1` and an instance with starting name `name11`. The PR changes the way a new name is generated by `CodegenContext.freshName` so that we generate unique names in this scenario too. ## How was this patch tested? added UT You can merge this pull request into a Git repository by running: $ git pull https://github.com/mgaido91/spark SPARK-23986 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/21080.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #21080 ---- commit 8623918adf88609f8a4e0ad6b69ad5c1d54bdc86 Author: Marco Gaido <marcogaido91@...> Date: 2018-04-16T12:58:02Z [SPARK-23986][SQL] freshName can generate non-unique names ---- --- --------------------------------------------------------------------- To unsubscribe, e-mail: reviews-unsubscr...@spark.apache.org For additional commands, e-mail: reviews-h...@spark.apache.org
