[jira] Reopened: (DERBY-625) hang in unit/cacheService.unit with
wctme5.7
[ https://issues.apache.org/jira/browse/DERBY-625?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Myrna van Lunteren reopened DERBY-625:
--------------------------------------
changing from fixed to invalid (for derby).
> hang in unit/cacheService.unit with wctme5.7
> --------------------------------------------
>
> Key: DERBY-625
> URL: https://issues.apache.org/jira/browse/DERBY-625
> Project: Derby
> Issue Type: Bug
> Components: Test
> Affects Versions: 10.1.1.0, 10.2.1.6
> Environment: windows with wctme5.7 (j9 version 2.2)
> Reporter: Myrna van Lunteren
> Priority: Minor
> Attachments: j9_22_hang.breakout
>
>
> Test unit/cacheService.unit hangs with wctme5.7 jvm since June...
> Can someone familiar with services please have a look?
> The hang was not noticed in a timely fashion because our scripts only run with wctme5.7 once a week,
> and for 3 months, our nightly tests took too long to complete - and no one paid attention (me included).
> I've done some historical research on this, but am no closer to deciding if this is a jvm bug exposed by changed derby functionality or a 'new' derby bug exposed by the wctme5.7 (j9 version 2.2) jvm.
> Efforts are hampered by
> - absence of commit archive details between June 13 and July 1
> - svn cannot backtrack to revisions that happened during incubator time
> This is what I found so far:
> - in main
> - the test ran fine on 6/18/2005, but failed on 6/25/2005.
> - From saved commits emails, it appears relevant revisions are between 191353 (jean)
> and 201792 (kathey), jean's are all dita related, 2 of kathey's are functionTests only changes.
> This leaves the following 2
> 201792 - kmarsden - DERBY-389,
> incubator/derby/code/trunk/java/engine/org/apache/derby/impl/sql/conn/GenericLanguageConnectionContext.java
> 191755 - kmarsden - DERBY-8 and DERBY-366; mostly test/master updates, but additionally changed:
> incubator/derby/code/trunk/java/engine/org/apache/derby/iapi/jdbc/BrokeredConnection.java
> incubator/derby/code/trunk/java/engine/org/apache/derby/iapi/jdbc/BrokeredConnection30.java
> - I backtracked the changes from these revisions but still the hang persists...
>
>
> - 10.1
> - I tested build 224373 and 208786 and the could reproduce the hang; but
> with build 190628 (which happened to be stting around on my machine) there was no hang.
> Thus, with 10.1 branch, the problem was introduced/backported between revision
> 190628 and revision 208786.
> - Looking at a combination of the commit archive for July and my saved commit emails, again, most of these are innocent test or dita updates.
> - The following are more interesting:
> - 201659 - satheesh - DERBY-388 -
> incubator/derby/code/branches/10.0/java/engine/org/apache/derby/impl/sql/GenericPreparedStatement.java
> - 208697 - dan - cleanup of published javadoc for embedded jdbc objects
> incubator/derby/code/branches/10.1/java/engine/org/apache/derby/jdbc/EmbeddedConnectionPoolDataSource.java
> incubator/derby/code/branches/10.1/java/engine/org/apache/derby/jdbc/EmbeddedDataSource.java
> incubator/derby/code/branches/10.1/java/engine/org/apache/derby/jdbc/EmbeddedDriver.java
> incubator/derby/code/branches/10.1/java/engine/org/apache/derby/jdbc/EmbeddedSimpleDataSource.java
> incubator/derby/code/branches/10.1/java/engine/org/apache/derby/jdbc/EmbeddedXADataSource.java
> - 208776 - andrew - monster commit backport fixes for DERBY-8, DERBY-247, DERBY-276,
> DERBY-348, DERBY-354,DERBY-361, DERBY-366, DERBY-389, DERBY-405, DERBY-416, and DERBY-420
> - I tried to backtrack my 10.1 branch to revision 208775, but that resulted in:
> svn: REPORT request failed on '/repos/asf/!svn/vcc/default'
> svn:
> Cannot replace a directory from within
> In short, historical research has gotten me nowhere.
> I looked at the stack of the threads when the program is hanging but it tells me nothing either.
> I will attached the stack threads obtained by running the following command:
> j9 -jcl:max -Xbootclasspath/p:c:/ive22/lib/database_enabler.jar;c:ive22/lib/classes.zip org.apache.derbyTesting.unitTests.harness.UnitTestMain
> on windows and subsequently pressing ctrl-break, and derby.log
> Note: this problem does not occur with wsdd5.6 (j9 version 2.1). The test never runs/ran with j9foundation (also wctme5.7).
