<section><title>Submitting Patches</title>
<p>
Create patches by getting the latest sources from Subversion.
Alter or add files as appropriate. Then, from the poi directiory,
type svn diff > mypatch.patch. This will capture all of your changes
in a patch file of the appropriate format. However, svn diff won't
capture any new files you may have added. So, if you've added any
files, create an archive (tar.bz2 preferred as its the smallest) in a
path-preserving archive format, relative to your poi directory.
You'll attach both files in the next step.
<p>
Patches are submitted via the <link href="http://issues.apache.org/bugzilla/buglist.cgi?product=POI">Bug Database</link>.
Create a new bug, set the subject to [PATCH] followed by a brief description. Explain you patch and any special instructions and submit/save it.
Next, go back to the bug, and create attachements for the patch files you
created. Be sure to describe not only the files purpose, but its format.
(Is that ZIP or a tgz or a bz2 or what?).

Software Foundation projects, do please try to submit early and often, rather
than "throwing a large patch over the wall" at the end.

<p>
Make sure your patches include the @author tag on any files you've altered
or created. Make sure you've documented your changes and altered the
examples/etc to reflect them. Any new additions should have unit tests.
Lastly, ensure that you've provided approriate javadoc. (see
<link href="http://poi.apache.org/resolutions/res001.html">Coding
Standards</link>). Patches that are of low quality may be rejected or
the contributer may be asked to bring them up to spec.

<p>If you use a unix shell, you may find the following following
sequence of commands useful for building the files to attach.</p>
<p>You may create your patch file using either of the following approaches (the committers recommend the first):</p>
<section><title>Approach 1 - use Ant</title>
<p>Use Ant to generate a patch file to POI: </p>
<source>
# Run this in the root of the checkout, i.e. the directory holding
# build.xml and poi.pom
# Build the directory to hold new files
mkdir /tmp/poi-patch/
mkdir /tmp/poi-patch/new-files/
# Get changes to existing files
svn diff > /tmp/poi-patch/diff.txt
# Capture any new files, as svn diff won't include them
# Preserve the path
svn status | grep "^\?" | awk '{printf "cp --parents %s /tmp/poi-patch/new-files/\n", $2 }' | sh -s
# tar up the new files
cd /tmp/poi-patch/new-files/
tar jcvf ../new-files.tar.bz2
cd ..
# Upload these to bugzilla
echo "Please upload to bugzilla:"
echo " /tmp/poi-patch/diff.txt"
echo " /tmp/poi-patch/new-files.tar.bz2"
ant -f patch.xml
</source>
<p>
This will create a file named patch.tar.gz that will contain a unified diff of files that have been modified
and also include files that have been added. Review the file for completeness and correctness. This approach
is recommended because it standardizes the way in which patch files are constructed. It also eliminates the
chance of you missing to submit new files that constitute part of the patch.
</p>
</section>
<section><title>Approach 2 - the manual way</title>
<p>
Patches to existing files should be generated with svn diff filename and save the output to a file.
if you want to get the changes made to multiple files in a directory , just use svn diff.
then, tar and gzip the patch file as well as any new files that you have added.
