--------------------------------
Attachment: derby-791-02-aa-printTargetColumnList.diff
Attaching derby-791-02-aa-printTargetColumnList.diff. This patch adds some more
accept methods so that InsertNodes walk their targetColumnLists in addition to
the children they share with their superclasses. Touches the following files:
M java/engine/org/apache/derby/impl/sql/compile/DMLModStatementNode.java
M java/engine/org/apache/derby/impl/sql/compile/InsertNode.java
> Expose api for printing Abstract Syntax Trees in production (non-debug)
> servers

> Currently you can print Abstract Syntax Trees to derby.log by setting the
> DumpParseTree tracepoint at server startup. E.g.:
> java -cp $CLASSPATH -Dderby.debug.true=DumpParseTree
> -Dderby.stream.error.logSeverityLevel=0 org.apache.derby.tools.ij z.sql
> This can be a useful debugging tool. However, it only works on debug servers
> built with the following flags:
> sanity=true
> debug=true
> We should provide some mechanism for printing these trees in production
> (non-debug) servers.
