HELP! severe, erratic bug
This is a very strange concerning problem and I think it may be a SEVERE
BUG. This post is long but I've tried to include everything necessary to
reproduce the problem. It was very difficult to craft the test code to
reproduce the problem because it's very erratic.
I'm trying to import my test data from flat text files and so I'm
populating foreign keys rather than the objects themselves then calling
PersistenceBroker.retrieveReference(?,?). I'm importing each class of
objects from flat text files one file at a time. The text files contain
the foreign keys and the objects are populated with them. In other
words, I'm not traversing the object graph from top to bottom while
importing but setting the foreign keys such that, after all data is
imported, OJB should have no problem materializing the object graph. The
database was generated by OJB using the autobuild=true property in
OJB.properties. I don't think this problem is related to data contraints
in any way. These are all simple 1:1 associations.
I've pasted in all the code etc below necessary to reproduce the
problem.
Thanks for your help in advance,
-Ken
****THE TEST CODE TO REPRODUCE THE PROBLEM
****IMPORTANT NOTE****
THE LOOP COUNTERS ARE AT 44. ALL DATA IS IMPORTED SUCCESSFULLY IF
COUNTERS ARE <41. BETWEEN 41 AND 51 It FAILS SOMETIMES. >51 IT ALWAYS
FAILS. IF THE LOOP IS MADE INTO ONE LOOP INSTEAD OF TWO, BY COMMENTING
THE TWO LINES BELOW STARTING WITH ****, THEN IT ALWAYS WORKS, EVEN AT
100 LOOPS! WHEN IT FAILS, IT FAILS AT THE LINE MARKED ****FAILS.

Good news!

Sorry, It did not see the class-descriptors and the persistent classes
code when I first read your mail.
Thinks are so easy. You defined your PK and FK attributes as Long in the
persistent classes.
But in the repository.xml you defined them to be of jdbc-type="INTEGER".
This does not match. the correct jdbc-type would have been "BIGINT".
See the jdbc-types.html document for details.

correct, this type mismatch will get you on loading instances from a
resultset!

yes, the cache might be the reason why this error popped up at random.
I hope you still enjoyed the weekend inspite of all this OJB problems :-)

RE: Solved. HELP! severe, erratic bug
Posted by Ken Brewer <kb...@microremedies.com>.
I found a fix for the problem. It's not an OJB bug. I changed the PK(and
FK) types in the classes from Long to Integer. Everything seems to work
OK now. It is still strange to me that it worked in some cases but not
in others and that's why I didn't suspect a data type problem initially.
It was also strange that the failure occurred at different iterations of
the loop sometimes. It seems that pushing to the db wasn't a problem.
The problem surfaced when OJB tries to populate the classes from the
DB(I think). Maybe it worked in some cases which OJB got the data from
cache instead of the DB. I say this because I put some println's in the
data retrieval code of OJB and noticed that they were only printed on
the failing loop iteration. That leads me to believe that the successful
iterations may have been loaded from cache instead of the db.
Cheers,
Ken

Re: HELP! severe, erratic bug
Posted by Ken Brewer <kb...@microremedies.com>.

Re: HELP! severe, erratic bug
Posted by Thomas Mahler <th...@web.de>.
Hi Ken,
As I was concerned that your report might reveal a severe bug
I rewrote your testcase against classes we have already in our
testsuite. Here is the code:
public void testMassOperations()
{
for (int i = 100; i < 200; i++)
{
broker.beginTransaction();
ProductGroup pg = new ProductGroup();
pg.setId(i);
pg.setGroupName("1-1 test productgroup " + i);
broker.store(pg);
broker.commitTransaction();
}
for (int i = 100; i < 200; i++)
{
broker.beginTransaction();
Article article = Article.createInstance();
article.setArticleId(i);
article.setArticleName("1-1 test article " + i);
article.setProductGroupId(i);
broker.retrieveReference(article, "productGroup");
broker.store(article);
broker.commitTransaction();
}
}
I tested it several times with 100 iterations. This test does *not* fail!
IMO this indicates that there is no bug in the tested OJB functionality.
I assume there is something wrong in your mapping repository.
Please post the code of your persistent classes Payee and Unit and the
respective class-descriptors from the repository.xml.
cheers,
Thomas

Collection help, please...
Posted by Brian McCallister <mc...@forthillcompany.com>.
I feel silly for not being able to figure this out, but I have not been
able to. I am sure it is some small configuration problem I have missed,
but looking over the docs, and my code, I cannot find it. Of note - OJB
.9.8, PostgreSQL 7.3, the standard pgsql jdbc3.0 driver.
When I attempt to instantiate a class (source follows) which has a
collection of other persistent objects in it, I get a nasty series of
JDBC exceptions.
I only have two classes for this setup, a User class and a Gift class -
the User contains a Vector of Gifts.
If there is a User in the database:
registry=> select * from users ;
userid | handle | password | firstname | lastname
--------+--------+----------+-----------+-------------
1 | wheee | tester | Brian | McCallister
(1 row)
and a gift for that user:
registry=> select * from gifts ;
giftid | name | foruserid
--------+--------------+-----------
1 | Wireless Hub | 1
(1 row)
before the tests run and I attempt to load said user I get the
exception. If i delete the gift frm the database I have no problem, if I
add a gift in the test and then load the user again, no problem, but if
the gift exists before I start running the test, boom it dies.
The test is simply loading the user via a query for the handle via the
PB API.
Any help would be much appreciated

Re: HELP! severe, erratic bug
Posted by Jason McKerr <mc...@nacse.org>.
I thought this had something to do with the sequence generator.
I ran into the same problem (or at least the same error message). I
don't know much about how the sequence manager works, but I put in data
through a SQL client, and relational data as well. Then when I loaded
the objects, it assigned a primary key to them from the database and
didn't use the foreign keys that where in the database, but generated
new ones. When I went into the SQL client and made the foreign keys the
same as the ones I was seeing generated, everything worked fine.
