Subject [jira] Updated: (DERBY-3831) RuntimeStatisticsParser can not distinguish names of table or index well and truly
Date Wed, 20 Aug 2008 01:20:44 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3831?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Junjie Peng updated DERBY-3831:
-------------------------------

    Component/s:     (was: Tools)
                 Test
     Derby Info: [Patch Available]

As Dag directed out, "RuntimeStatisticsParser  is part of the testing infrastructure. I think
we use the test
category for that, cf. this file (RuntimeStatisticsParser.java) was
originally created by JIRA DERBY-2463 which is labelled with Category
Test. The tools category is reserved for the runnable tools like ij,
sysinfo, dblook and some utilities like install_jar, export and
import."  So, change its components from Toos to Test.

> RuntimeStatisticsParser can not distinguish names of table or index well and truly.
> i.e. there are two indexes t1_c1c2 and t1_c1 on table t1. Execute "select * from t1 --DeRbY-pRoPeRtIeS
index = t1_c1c2"  on t1. Then,RuntimeStatisticsParser.usedSpecificIndexForIndexScan("T1","T1_C1C2")
will return true, while RuntimeStatisticsParser.usedSpecificIndexForIndexScan("T1","T1_C1")
will return true too. It's not correct.
> The similar errors also exist on usedIndexScan(), usedIndexRowToBaseRow(), usedDistinctScan()
and usedTableScan() in the class of  RuntimeStatisticsParser.
