# Bug database

This page gives you some bookmarks to use the Bugzilla Apache Bug Database.

This link issues.apache.org connects you to the complete list of Apache Bug Database systems.

#### Has It Been Reported?

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 the bug database. This system is easy to use, and it will let you search the currently open 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 `CC` list to follow the progress of this bug.

Open Apache Ant bugs by order of priority.

#### Filing a Bug Report

Please read our document about problems before deciding that there is an unreported bug in Apache Ant.

You have a few choices at this point. You can send an email to the `user` 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.

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.

#### Asking for an Enhancement

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 enhancement request. 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.

#### Fixing the Bug

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 source distributions. If you are going to tackle the problem at this level, you may want to discuss some details first on the `dev` mailing list. Once you have a fix for the problem, you may submit the fix as a patch to either the `dev` 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.

If you have a patch to submit and are sending it to the `dev` 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 `-u` option of the `diff` or `svn diff` command. For example:
diff -u Javac.java.orig Javac.java > javac.diffs
or, if you have source from Subversion:
svn diff Javac.java > javac.diffs
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.
