Subject [jira] Created: (DERBY-4322) intermittent test failure in derbynet/runtimeinfo
Date Mon, 27 Jul 2009 21:16:15 GMT
intermittent test failure in derbynet/runtimeinfo
-------------------------------------------------

                 Key: DERBY-4322
                 URL: https://issues.apache.org/jira/browse/DERBY-4322
             Project: Derby
          Issue Type: Bug
          Components: Test
    Affects Versions: 10.5.2.0
         Environment: Linux/VMware with IBM 1.5 or 1.6; IBM iseries (AS 400/ V5R4M0) with
IBM 1.6
            Reporter: Myrna van Lunteren


A few times in regression testing of builds of the 10.5 branch, and also with the testing
cycle of 10.5.2.0 on iseries I've seen failures in derbynet/runtimeinfo.

They look like differences in the Session id and timing differences in return of text to the
client.
For instance, this is with ibm 1.6 on iseries:
---------------------------------------
5 del
< Session # :2
5a5
> Session # :52
12 del
< Session # :3
12a12
> Session # :86
23 del
< Session # :2
23a23
> Session # :52
32 del
< Session # :4
32a32
> Session # :88
41 del
< Session # :5
41a41
> Session # :90
48 del
< Session # :6
48a48
> Session # :113
58 del
< Session # :7
58a58
> Session # :117
---------------------------------------

And this is an example of a failure on linux/vmware on 7/15/09 (10.5.1.2 revision: 794133)

---------------------------------------
5 del
< Session # :2
5a5,6

> 	SYSLH0001	SELECT count(*) from sys.systables
> Session # :62
> Database :wombat;create=true
> User :APP
> # Statements:2
> Prepared Statement Information: 
> 	Stmt ID		SQLText
> 	-------------	-----------
32 del
< Session # :4
32a41
> Session # :92
35,43d43
< # Statements:2
< Prepared Statement Information: 
< 	Stmt ID		SQLText
< 	-------------	-----------
< 	SYSLH0002	VALUES(2)
< 	SYSLH0001	SELECT count(*) from sys.systables
< Session # :5
< Database :wombat;create=true
< User :APP
48 del
< Session # :6
48a48
> Session # :101
58 del
< Session # :7
58a58
> Session # :108
---------------------------------------

It seems to me these are fairly innocent, and if they are, then possibly the solution is to
backport the conversion of runtimeinfo to junit to 10.5. (see DERBY-3834, revisions 792001
and 792254.)
