Bug Database
</h3>
<p>
This page gives you some bookmarks to use the Bugzilla <a href="http://issues.apache.org/bugzilla/">
Apache Bug Database</a>.
</p>
<p>
This link <a href="http://issues.apache.org/">issues.apache.org</a> connects you
to the complete list of Apache Bug Database systems.
</p>
<h4 class="subsection">
<a name="Has It Been Reported?"></a>
Has It Been Reported?
</h4>
<p>
If the current nightly build doesn't resolve your problem, it is
possible that someone else has reported the issue. It is time to
look at . This system is easy to use, and it will
let you search the <a href="http://issues.apache.org/bugzilla/buglist.cgi?bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&email1=&emailtype1=substring&emailassigned_to1=1&email2=&emailtype2=substring&emailreporter2=1&bugidtype=include&bug_id=&changedin=&votes=&chfieldfrom=&chfieldto=Now&chfieldvalue=&product=Ant&short_desc=&short_desc_type=substring&long_desc=&long_desc_type=substring&bug_file_loc=&bug_file_loc_type=substring&keywords=&keywords_type=anywords&field0-0-0=noop&type0-0-0=noop&value0-0-0=&order=bugs.bug_id">
currently open</a> and resolved bugs to see if your problem has
already been reported. If your problem has been reported, you can
see whether any of the developers have commented, suggesting
workarounds, or the reason for the bug, etc. Or you may have
information to add (see about creating and modifying bug reports
below), in which case, go right ahead and add the information.
If you don't have any additional information, you may just want
to vote for this bug, and perhaps
add yourself to the <code>CC</code> list to follow the progress
of this bug.

<h4 class="subsection">
<a name="Filing a Bug Report"></a>
Filing a Bug Report
</h4>
<p>
Please read our document about <a href="problems.html">problems</a>
before deciding that there is an unreported
bug in Ant.
</p>
<p>
You have a few choices at this point. You can send
an email to the <code>user</code> mailing list
to see if
others have encountered your issue and find out how they may
have worked around it. If after some discussion, you feel it
is time to create
a bug report, this is a simple operation in the bug database.
Please try to provide as much information as possible in order
to assist the developers in resolving the bug. Please try to enter
correct values for the various inputs when creating the bug, such
as which version of Ant you are running, and on which platform,
etc. Once the bug is created, you can also add attachments to
the bug report.
</p>
<p>
What information should you include in your bug report? The
easiest bugs to fix are those that are most easily reproducible,
so it is really helpful if you can produce a small test case that
exhibits the problem. In this case, you would attach the build file
and any other files necessary to reproduce the problem, probably
packed together in an archive. If you can't produce a test case,
you should try to include a snippet from your build file and the
relevant sections from the verbose or debug output from Ant. Try
to include the header information where Ant states the version,
the OS and VM information, etc. As debug output is likely to be
very large, it's best to remove any output that is not
relevant. Once the bug is entered into the bug database, you
will be kept informed by email about progress on the bug. If
you receive email asking for further information, please try to
respond, as it will aid in the resolution of your bug.
</p>
<p>
To create the bug report hit this
<a href="http://issues.apache.org/bugzilla/enter_bug.cgi?product=Ant">
link</a>.
</p>
<h4 class="subsection">
<a name="Asking for an Enhancement"></a>
Asking for an Enhancement
</h4>
<p>
Sometimes, you may find that Ant just doesn't do what you need it
to. It isn't a bug, as such, since Ant is working the way it is
supposed to work. Perhaps it is some additional functionality for
a task that hasn't been thought of yet, or maybe a completely new
task. For these situations, you will
want to raise an <i>enhancement request</i>. Enhancement requests
are managed using the same Apache Bug Database described above.
These are just a different type of bug report. If you look in the
bug database, you will see that one of the severity settings for
a bug is "Enhancement". Just fill the bug report in,
set the severity of the bug to "Enhancement", and
state in the description how you would like to have Ant enhanced.
Again, you should first check whether there are any existing
enhancment requests that cover your needs. If so, just add your
vote to these.

<h4 class="subsection">
<a name="Fixing the Bug"></a>
Fixing the Bug
</h4>
<p>
If you aren't satisfied with just filing a bug report, you can
try to find the cause of the problem and provide a fix yourself.
The best way to do that is by working with the latest code from Subversion.
Alternatively, you can work with the source code available from the
<a href="http://ant.apache.org/srcdownload.cgi">
source distributions</a>. If you
are going to tackle the problem at this level, you may want to
discuss some details first on the <code>dev</code>
mailing list. Once you have a fix for the problem, you may submit
the fix as a <i>patch</i> to either the
<code>dev</code> mailing
list, or enter the bug database as described above and attach the
patch to the bug report. Using the bug database has the advantage
of being able to track the progress of your patch.
</p>
<p>
If you have a patch to submit and are sending it to the
<code>dev</code> mailing list,
prefix "[PATCH]"
to your message subject (this is also a good idea for
a subject line in the bug database).
Please include any relevant bug numbers.
Patch files should be created with the <code>-u</code>
option of the
<code>diff</code> or <code>svn diff</code> command. For
example:<br /><br />
<font face="verdana" size="-1">
diff -u Javac.java.orig Javac.java > javac.diffs<br /><br />
</font>
or, if you have source from Subversion:<br /><br />
<font face="verdana" size="-1">
svn diff Javac.java > javac.diffs<br /><br />
</font>
Note: You should give your patch files meaningful names.
This makes it easier for developers who need to apply a number
of different patch files.
