[jira] Created: (TUSCANY-1295) Resolve Memory Leaks in RDB DAS
source and test cases code
Resolve Memory Leaks in RDB DAS source and test cases code
----------------------------------------------------------
Key: TUSCANY-1295
URL: https://issues.apache.org/jira/browse/TUSCANY-1295
Project: Tuscany
Issue Type: Bug
Components: Java DAS RDB
Affects Versions: Java-DAS-M3
Reporter: Amita Vadhavkar
It is seen that as the number of test cases in RDB DAS JUnit testing increase, the memory consumption increase
and beyond a certail limit, there is OutOfMemory exception for heap memory. This JIRA is created to elaborate the
cause-solution for this and provide the fix.

Hi Amita,
I got a problem with the file MultiSchemaTests.java. It seems mixed the data of three files in one. Cause there are three MultiSchemaTests class defined along the file. I haven't check if they are the same, like if someone copied the class and pasted twice in the same file. Can you check this out?
The same happens on MultiSchemaData.java.

Hi Adriano,
First apologies as my connection to chat dropped for 40 mins, some n/w issues.
Now in the JIRA1295_952_May22.txt below are the lines -
704-795-MultiSchemaData, 1159-1181-MultiSchemaTests
Here in the patch file itself the code is not appearing more than once, so
when applying the patch on the code from trunk same should be the case.
I verified it by applying on the trunk code too.
Is there a chance that you are applying this patch on the top of some
previous patch? (I also found that revert command from svn is removing
these 2 files from svn but keeping a local copy in the eclipse workspace.
So, if you are having an old workspace and might have done revert on some
old patch, these 2 files in questions will still be there locally, though
not under version control. And then if you apply the May 22nd patch, you
may be getting this issue.)
In that case, please take a fresh code from trunk and apply
this patch, it should not give any duplicate / triplicate code.
Please let me know what you find.
Regards,
Amita

Attachment: JProfReportsMay21.zip
JIRA1295_952_May21.txt
Below is the analysis. attached are jprofiler reports for each check point.
In summary, 2) will suffice for now to have least changes, but the real
improvement will be by using 3) and 4). Also, need inputs about why the
members are final in 5).
Other than finalize() all other code changes are in UT cases and are marked
with //MM.
As, this JIRA is opened when OutOfMemory was detected during adding
test cases for JIRA-952, the attached patch has changes for JIRA-1295 as well as
JIRA-952. JIRA-952 changes are already reviewed and are marked with //JIRA-952.
0) plain code from trunk
CHECK POINT 0
mvn 7M/12M
jprofiler- FromTrunk_May21
1) add multi schema code, no test cases
CHECK POINT 1
mvn 10M/22M
jprofiler AddedMultiSchema_May21
2) add test cases with small config files
CHECK POINT 2
mvn 10M/23M
jprofiler AddedMultiSchemaUT_May21
3)add finalize()
CHECK POINT 3
mvn 10M/24M
jprofiler AddedFinalize_May21
4)add Connection Pool and separate DasTest and DatabaseSetup
CHECK POINT 4
mvn 6M/14M
jprofiler AddedConnectionPool_May21
5) As Config seems to be the culprit, some more considerations:-
DeleteCommandImpl, DatabaseObject, ResultMetaData - why ConfigWrapper is made final?
HeapWalker shows improvement after 3) and 4)
Also, comparing 3) with 4) , mvn results shows drastic improvement.
