The code that set up data to be passed to user-defined functions was very old and analyzed the "Type" of the data that was passed into the UDF, when it really should analyze the "return_type", which is hard-coded for simple Items and works correctly for complex ones like functions. --- Added test at Sergei's behest. mysql-test/r/udf.result: Verify that various arguments work. --- Added test at Sergei's behest. mysql-test/t/udf.test: Verify that various arguments work. --- Added test at Sergei's behest. sql/item_func.cc: For function-Items, test whether it is constant and set the struct members for the UDF parameter appropriately. Replace tabs with spaces in affected code. sql/udf_example.c: Include a simple function that is useful in testing.
