Julian Hyde updated CALCITE-1602:
---------------------------------
Summary: Remove uses of deprecated APIs (was: Remove uses of deprecated
external APIs)
> Remove uses of deprecated APIs
> ------------------------------
>
> Key: CALCITE-1602
> URL: https://issues.apache.org/jira/browse/CALCITE-1602
> Project: Calcite
> Issue Type: Bug
> Reporter: Julian Hyde
> Assignee: Julian Hyde
>
> Calcite should not use deprecated methods and classes, especially in
> third-party libraries. I propose that we adopt a zero-tolerance policy,
> fixing deprecated calls as soon as they occur. As long as the third-party
> libraries use semantic versioning, this should give us prior warning before
> things disappear.
> You can find the calls to deprecated APIs by adding
> {{<compilerArgument>-Xlint:deprecation</compilerArgument>}} then running
> {{mvn clean package -DskipTests | grep 'has been deprecated' | grep -v 'in
> org.apache.calcite'}}. Currently there are 51 when you run in JDK9 and Guava
> 20.0. Here are the first few:
> {noformat}
> [WARNING]
> /home/jhyde/open1/calcite.2/linq4j/src/main/java/org/apache/calcite/linq4j/tree/Types.java:[254,38]
> getPackage(java.lang.String) in java.lang.Package has been deprecated
> [WARNING]
> /home/jhyde/open1/calcite.2/linq4j/src/test/java/org/apache/calcite/linq4j/test/Linq4jTest.java:[736,25]
> Integer(int) in java.lang.Integer has been deprecated
> [WARNING]
> /home/jhyde/open1/calcite.2/linq4j/src/test/java/org/apache/calcite/linq4j/test/Linq4jTest.java:[737,26]
> Integer(int) in java.lang.Integer has been deprecated
> [WARNING]
> /home/jhyde/open1/calcite.2/linq4j/src/test/java/org/apache/calcite/linq4j/test/Linq4jTest.java:[738,25]
> Integer(int) in java.lang.Integer has been deprecated
> [WARNING]
> /home/jhyde/open1/calcite.2/core/src/main/java/org/apache/calcite/rex/RexBuilder.java:[539,47]
> ROUND_HALF_DOWN in java.math.BigDecimal has been deprecated
> {noformat}
> We should fix these (and other deprecated APIs when we run on other JDK
> versions and other Guava versions), then add a nightly check that none are
> added back.
