Re: [hibernate-dev] mutable versus immutable natural keys

However, I think at the same time we should be more explicit and consistent about what it means when we say that a mapped natural key is mutable or immutable. Basically, is immutable a hint from the user that the values cannot change (so that we can perform certain optimizations)? Or is immutable a mandate that we have to verify the natural key has not changed, either through Hibernate or behind us? Today we kind of have a blend of those two. Personally I think we should take it as a hint from the user that the values will not change. WDYT? Would the hint mechanism involve any detection of changed values at all? What would the user see if a natural key were changed? -CB ___ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
Re: [hibernate-dev] Hibernate Core is now using Git
Z-Shell also has good native (?) command completion for git and ships with both GNU/Linux and OS X...

We have quite a bit of this type of integration code in Hibernate already that goes unmaintained for long spurts of time. And truth be told a lot of it deals with DB2 variants and WebSphere which of course makes me a little even more leery here. So for this aspect we would need you (or someone) to take ownership of this code. If you agree to that we can discuss those particulars off list. Also realize that the contributions *must* be LGPL. We have had issues with that previously with regards to IBM employees and IBM's legal teams from LGPL FUD.

Re: [hibernate-dev] Dialect support for SQL comments.
Daniel,
Thanks for the work on this. You should file a JIRA and include your
patch there so it can be considered for inclusion.
Cheers,

Daniel Bell wrote:
Hi,
I have recently tried turning on SQL comments in hibernate 3.2.6.ga.
However, I found that our database (informix 7.31) did not support SQL
where the comment was at the start of the comment. Instead, the comment
needed to be after the SQL. For example:
/* not accepted by informix 7.31*/ select * from systables;
select * from systables /* accepted by informix 7.31*/
Because of this, I have added a method to the Dialect for adding comments:
/**
* Add a comment to the SQL string.
*
* @param sql StringBuffer holding the SQL.
* @param comment Comment to add to the SQL. May be null.
*/
public void addCommentToSql(StringBuffer sql, String comment) {
if (StringHelper.isNotEmpty(comment))
sql.insert(0, /* + comment + */ );
}
Thus, the default implementation provides the same functionality as
before. However, derived Dialects may override this method to add the
comment in a different location.
It is also possible to add additional comments in the derived Dialect.
In our case, we also add the Java thread ID.
I have included a complete patch for this change for hibernate 3.2.6.GA.
Please consider its inclusion in Hibernate.
Thanks,
Daniel.

Re: [hibernate-dev] want to join hibernate development community
Some observations on this thread: 1. You do not need m2eclipse. /trunk and /Branch_3_3 both use Maven 2 and will build straight away with mvn compile. 2. You can generate Eclipse or IDEA project files from the command line in the standard Maven way (mvn eclipse:eclipse or mvn idea:idea) and then import the projects. I understand that IDEA reads Maven metadata natively but I cannot speak to that. 3. Only committers are allowed to ... commit. This is what the svn.jboss.org server is for. anonsvn.jboss.org is a replica with read-only privileges. Use this for now. You are free to open JIRA tickets and attach patch files which will be reviewed by Hibernate committers and possibly committed in a future release. 4. Yes, Hibernate is complicated. It is not a trivial project to jump into head-first.

Hibernate query engine processes each identifier in a query to see if its a Java Class. So for each one of ClassA, a.identifier etc it calls Class.forName, if NoClassDefFound exception is thrown, ReflectHelper.getConstantValue returns null. Now the problem is, if the expression is huge, recursive calls to /NodeTraverser.visitDepthFirst create huge stack trace. While building ClassNotFoundException, system class loader gets stuck to build all this stack trace. Because weblogic/utils/classloaders/ChangeAwareClassLoader.loadClass method is synchronized, any other thread trying to load any other class is blocked. If the stack trace is huge and taking consideratble amount of time to create Exception object, the lock is held for that much time, blocking every other thread trying to any the class. It brought down our servers in test environment. Is this a known issue in weblogic and hibernate? I know that building such a large expression is bad(and we have already changed the code which was doing that), but the way its blocking the classloader in weblogic is an issue I think. Following is the thread dump.

Re: [hibernate-dev] CharacterTypeMapping within Oracle10gDialect
A CLOB is an entirely different animal than a text/char/varchar column.
I'd be somewhat surprised to find out that my Types.VARCHAR got turned
into a LOB, personally - even if they are not recommended on Oracle. Of
course you can extend the Dialect in any way you see fit, or just map
your property as a CLOB from the get go. Not that I'm not a fan of
CLOBs, I am; it's just that VARCHAR conceptually maps better to a long
than to a CLOB.
My 2 cents :)
Thorsten Gast wrote:
Hi,
I just wonder if there is any reason, why the Oracle10gDialect uses the

know is the usage of long-columns in Oracle10g deprecated and should be
replaced by clobs.
Shouldn't look the mapping something like this?
snippet
protected void registerCharacterTypeMappings() {
registerColumnType( Types.CHAR, char(1 char) );
registerColumnType( Types.VARCHAR, 4000, varchar2($l char) );
registerColumnType( Types.VARCHAR, clob );
}

Or are there any reasons why I should prefer the usage of long-columns within
hibernate.

[hibernate-dev] mvn eclipse:eclipse
All, I'm not sure when this broke, but Maven 2.0.9 (perhaps others) will not create Eclipse projects using 'mvn eclipse:eclipse'. Even though the various modules are indeed aggregated in a multi-module POM, the plugin insists on inter-referencing the modules as jars rather than project dependencies. This is caused by this bug: http://jira.codehaus.org/browse/MNG-3283 The workaround listed on the JIRA is solid. To create Eclipse projects from a fresh checkout of trunk or 3.3, you can use this: mvn -DdisableDistribution=true process-classes eclipse:eclipse Hope this saves a little frustration for someone. -Chris ___ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev

Re: [hibernate-dev] Contributed with HiRDB Dialect
Tomoto-san, I've had a conversation with Steve regarding the addition of new Dialects such as the one you've proposed. Here are the options: 1. Integrate a new org.hibernate.dialect.HiRDBDialect into Hibernate's source code. This is reasonable for mainstream highly used databases that most users would expect us to provide support for. In this scenario, there's an implied responsibility on behalf of the Hibernate team to ensure that they remain usable as Hibernate and the RDBMS evolves. While it's great to get contributions for new and interesting platforms, sometimes this happens one time only and in 5 years, we're left with a Dialect that nobody can use and nobody is available to maintain it. 2. Integrate a new org.hibernate.dialect.HiRDDialect into an optional distribution that users are free to download and use at their leisure. This is a good choice for less used integration pieces that may be less actively maintained than core code. We are open to this for your case but it would take some time to set up (Steve can comment on exactly when this might take place). 3. Ship HiRDBDialect as a download from hitachi.co.jp or part of the HiRDB JDBC distribution (in a com.hitachi.* package). I actually like this option a lot because it is clear who owns/maintains the code. Also, new versions of the Dialect can be shipped as HiRDB evolves and releases new versions. Including it with the JDBC driver would make the Hibernate dialect available automatically to anyone who needs it. What do you think of option 3? Is this something you can facilitate along with the team that maintains the JDBC driver? We will be happy to provide links to the downloadable Dialect on hibernate.org so that users can find things easily. If this is not an option, I'll discuss the creation of an extras module that can house code like this. We may have to do this already because there are some existing bits of code that really should not be part of the core distribution for reasons outlined above. There's also the issue of testing. I don't envision acquiring hardware and licenses to HiRDB so that we can make it part of our QA suite. Shipping a Dialect as part of the core distribution tends to give users the impression that we are 100% confident in its quality (even if our web site says differently). We clearly can't be 100% confident in code quality when we don't actively test against a given scenario. Based on this I think option 3 is the best but please let me know if this can work for you. Cheers, Chris Tomoto Shimizu Washio wrote: Hi Chris, Unfortunately, there is no free version of HiRDB.

JTATransaction has and always has had a dependency on JNDI. It's only been recently uncovered because a) we changed how/when the transaction was instantiated and b) it turns out some folks are using JTA services outside the container that don't bind to JNDI. If you want to use such a service, you're exactly right - also use a JNDI service or create a TransactionFactory/Transaction combo that doesn't need JNDI. This is trivial IMHO (though I haven't done it). And of course if you do this, please share :) -Chris ___ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev

I haven't looked closely enough to comment on the query problem but I can confirm that your assessment above is correct. JTATransaction has and always has had a dependency on JNDI.

If you want to use such a service, you're exactly right - also use a JNDI service or create a TransactionFactory/Transaction combo that doesn't need JNDI. The strange thing is that I'm also using JNDI with my Transaction Manager - System.setProperty(java.naming.factory.initial, org.apache.naming.java.javaURLContextFactory);. And Hibernate is fetching the JTA service using the following lookup class: http://docs.codehaus.org/display/BTM/Hibernate#Hibernate-Transactionmanagerlookupclass Using the following Hibernate config: property name=transaction.manager_lookup_class db.BitronixTransactionManagerLookup /property property name=transaction.factory_class org.hibernate.transaction.JTATransactionFactory /property As I understood from your post on issue HHH-3110, Hibernate should not use a lookup class anymore but create (instance) the Transaction Manager. Am I right ? If so, to do this, I should implement a org.hibernate.transaction.TransactionFactory for my transaction manager ? You can do whichever works. Using the default JTATransaction, you'll need JNDI. But you can alternatively provide your own Impl that does not rely on JNDI. Your choice really, and all this is pluggable so Hibernate won't care. -Chris ___ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
