<h2 id="support">Reporting Problems or Requests</h2>
<p>
Please consider the following checklist if you have a question, want to report a problem,
or if you have a feature request:
</p>
<ul><li>Feature requests are always welcome, even if the feature is already on the
<a href="roadmap.html">roadmap</a>. Your mail will help prioritize feature requests.
If you urgently need a feature, consider <a href="#providing_patches">providing a patch</a>.
</li><li>Before posting problems, check the
<a href="faq.html">FAQ</a> and do a <a href="http://google.com">Google search</a>.
</li><li>When got an unexpected exception, please try the
<a href="sourceError.html">Error Analyzer tool</a>. If this doesn't help,
please report the problem, including the complete error message and stack trace,
and the root cause stack trace(s).
</li><li>When sending source code, please use a public web clipboard such as
<a href="http://pastebin.com">Pastebin</a>,
<a href="http://cl1p.net">Cl1p</a>, or
<a href="http://www.mysticpaste.com/new">Mystic Paste</a>
to avoid formatting problems.
Please keep test cases as simple and short as possible,
but so that the problem can still be reproduced.
Method that simply call other methods should be avoided,
as well as unnecessary exception handling.
Please use the JDBC API and no external tools or libraries.
The test should include all required initialization code, and
should be started with the main method.
</li><li>For large attachments, use a public temporary storage such as
<a href="http://rapidshare.com">Rapidshare</a>.
</li><li>Google Group versus issue tracking:
Use the
<a href="http://groups.google.com/group/h2-database">Google Group</a>
for questions or if you are not sure it's a bug.
If you are sure it's a bug, you can create an
<a href="http://code.google.com/p/h2database/issues/list">issue</a>,
but you don't need to (sending an email to the group is enough).
Please note that only few people monitor the issue tracking system.
</li><li>It may take a few days to get an answers. Please do not double post.
</li></ul>

<h1>Change Log</h1>
<h2>Next Version (unreleased)</h2>
<ul><li>Page store: a rollback of a relatively large transaction could fail with an ArrayIndexOutOfBoundsException
<ul><li>The ChangeFileEncryption and Backup tools will now fail with an exception
if the database is still in use.
</li><li>CSVREAD: when reading the column names from the CSV file, column names that contain
no special characters are considered case insensitive now.
</li><li>Optimization index conditions of the form 'column=NULL' (which is always false; unlike 'column IS NULL').
</li><li>Script command and tool: the primary key constraint is now listed before inserting the data.
This will result in a smaller database when using the page store.
</li><li>Statements with IN(..) conditions could produce the wrong result when using views or nested select statements.
Example: index on id; index on name; query: select * from (select * from test) where id=1 and name in('a', 'b').
select * from (select * from test) where id=1 and name in('Hello', 'World').
</li><li>Page store: a rollback of a relatively large transaction could fail with an ArrayIndexOutOfBoundsException
or a 'row not found' exception in the PageBtreeIndex in some cases.
</li><li>JaQu: the decompiler has been improved, and a few test cases already work. It is still incomplete however.
</li><li>LIKE: any letter is now allowed after the escape character (which is still '\' by default).
Previously, an exception was thrown (unlike other databases) if it was not the escape character, '_' or '%'.
If the escape character appears at the end of the pattern, the result is it is ignored (like PostgreSQL and MS SQL Server).
</li><li>The reserve heap memory is no longer used.
</li><li>Fixed NullPointerException in Database.checkpoint().
</li><li>Database.checkpoint() could throw a NullPointerException.

There are a number of files created for persistent databases. Unlike some other databases,
not every table and/or index is stored in its own file. Instead, usually only the following files are created:
a data file, an index file, a log file, and a database lock file (exists only while the database is in use).
In addition to that, a file is created for each large object (CLOB/BLOB) larger than a certain size,
and temporary files for large result sets.
If the database trace option is enabled, trace files are created.

* Feature requests are always welcome, even if the feature is already on the roadmap.
Your mail will help prioritize feature requests.
If you urgently need a feature, consider providing a patch.

*
Sending source code: to avoid formatting problems, consider using a public web clipboard such as

You don't need to create issue reports, sending an email to the group is enough.
If you want, you can create an issue.
* Keep your test cases and email as short as possible.
Specially when creating test cases, please keep the code as simple and short as possible,
