[jira] Updated: (DERBY-1872) Backport lang/wisconsin.java at
10.2.0.4-alpha to the 10.1 branch
[ http://issues.apache.org/jira/browse/DERBY-1872?page=all ]
John H. Embretsen updated DERBY-1872:
-------------------------------------
Attachment: port-wisconsin-from-10.2.0.4-to-10.1_v2.stat
port-wisconsin-from-10.2.0.4-to-10.1_v2.zip
Attaching patch for porting the lang/wisconsin.java test from its state in 10.2.0.4 to the 10.1 branch.
This patch, 'port-wisconsin-from-10.2.0.4-to-10.1_v2.zip' ('.diff' when unzipped), replaces the _v1, patch that was attached to DERBY-1564. There is only one change from the _v1 patch:
* Added lang/wisc_setup.sql to lang/copyfiles.ant, so that it gets included in
the build. copyfiles.ant is no longer needed in trunk or 10.2 (DERBY-892), so it
took me a while to figure out what caused my build problem with the _v1-patch,
and why. The build works fine with the _v2 patch.
Here is a summary of changes provided by the patch:
- renames the test from lang/wisconsin.sql to lang/wisconsin.java (DERBY-398)
- adds wisc_setup.sql support file (DERBY-398)
- removes framework-specific master files (for DerbyNet and DerbyNetClient) (DERBY-1014)
- runs compress on tables before retreiving runtimestatistics (DERBY-937)
- adds property derby.optimizer.noTimeout=true to wisconsin_derby.properties (DERBY-413/DERBY-937)
(I do not expect any problems related to DERBY-822 (as mentioned in the _v1 patch description), as the changes relating to the wisconsin test stems from DERBY-1014 _in preparation for_ DERBY-822, not DERBY-822 itself.)
Please note that the patch requires several 'svn add' and 'svn delete' commands, as shown in 'port-wisconsin-from-10.2.0.4-to-10.1_v2.stat'.
The patch is zipped because it is 3.3 MB uncompressed.
I have tested this patch by running:
* lang/wisconsin.java (10.1), single-runs in all three frameworks on
* Solaris 10 x86, Sun JVM 1.5.0_07 - passed
* Solaris 10 x86, Sun JVM 1.4.2_12 - passed
* Solaris 10 x86, Sun JVM 1.3.1_15 - passed
* derbyall on Solaris 10 x86, Sun JVM 1.5.0_07 - 1 unrelated failure, derbynetmats/testSecMec.diff
Please review/commit if you think this adds value to the 10.1 branch.

> Investigations relating to DERBY-1564 ("wisconsin.java test failed in DerbyNet or DerbyNetClient frameworks, VM for network server got OutOfMemoryError") revealed that comparing memory usage for the lang/wisconsin.[java|sql] test in 10.1.x versus 10.2.x was like comparing apples and oranges. After the 10.1 branch was created, several updates were made to the wisconsin test in trunk that were not backported to 10.1, e.g:
> * giving the optimizer unlimited time to choose query plans
> * compressing the tables to avoid the instabilities reported in DERBY-937
> Backporting the test will make it less unfair to compare 10.1 vs. 10.2 (or trunk) test results and memory usage, and it will make it easier to determine if failures (such as DERBY-1564) are regressions or not. On the other hand, other differences between the branches that may influence the test will remain, so this will not be a wonder cure.
> The failures seen in DERBY-1564 were mainly caused by bugs (DERBY-1091, DERBY-1614) in the test harness, causing the wisconsin test for the 10.2.0.4 snapshot to run with low memory settings. These issues have been fixed.
> The most practical backporting approach will probably be to take the wisconsin test as it was in the 10.2.0.4-snapshot (SVN revision 423199), and port it to the current 10.1 branch. Other changes have been made to the wisconsin test in trunk/10.2 after 10.2.0.4, but to avoid various dependencies (e.g. DERBY-1609), these should not be backported.
