== Keeping the branch up to date using svnmerge.py ==
As you develop your branch, changes will be occurring simultaneously within the main line. These changes should be merged into your branch on a regular basis to avoid large incompatible changes from forming between the two branches. To simplify this process, the svnmerge.py script located at [http://www.orcaware.com/svn/wiki/Svnmerge.py http://www.orcaware.com/svn/wiki/Svnmerge.py] can be used. It is best to download the trunk version from that page, unless that version is non-functional.
<source lang="bash">
cd ${BRANCH}_svn
# Get the svnmerge script
curl http://svn.apache.org/repos/asf/subversion/trunk/contrib/client-side/svnmerge/svnmerge.py -o $HOME/bin/svnmerge.py
chmod +x $HOME/bin/svnmerge.py
#Once you have this script, the merging from the main line to your private branch must be initialised by typing, from within the checked out copy of your branch
svnmerge.py init
#This then needs to be committed using the automatically generated log
svn ci -F svnmerge-commit-message.txt
rm svnmerge-commit-message.txt
# See log
svn log -l 5
# To keep up to date, simply type
svnmerge.py avail
svnmerge.py merge
</source>
If conflicts have occurred please refer to the Subversion book at [http://svnbook.red-bean.com/ http://svnbook.red-bean.com/] for information on how to resolve the problem. Otherwise, or once fixed, the main line revisions merged into your branch can be committed using the automatically generated log file:
<source lang="bash">
svn ci -F svnmerge-commit-message.txt
</source>
=== BUG: svnmerge: no integration info available ===
If you receive a message like: '''svnmerge: no integration info available'''.<br>
Then you have probably run '''svnmerge.py''' before updating.
Solution, run: '''svn revert .'''
<source lang='bash'>

== Merging the branch back into the main line ==
Once you have completed the modifications desired for your branch, all changes which have occurred in the main line have been merged using svnmerge.py, and the changes have been approved for merging back into the main line - then your branch can be merged. First check out a copy of the main line,
<source lang="bash">
svn co svn+ssh://$RUSER@svn.gna.org/svn/relax/trunk relax-trunk
# or update a previously checked out version,
svn up
</source>
Then svnmerge.py can be utilised again. First initialise the merging process by typing, from within the checked out copy of the main line,
<source lang="bash">
svnmerge.py init svn+ssh://$RUSER@svn.gna.org/svn/relax/branches/$BRANCH
#Then commit the change
svn ci -F svnmerge-commit-message.txt
</source>
To merge the branch and commit the changes, type
<source lang="bash">
svnmerge.py merge -bidirectional
svn ci -F svnmerge-commit-message.txt
</source>
Finally the merge properties need to be removed
<source lang="bash">
svnmerge.py uninit -S svn+ssh://$RUSER@svn.gna.org/svn/relax/branches/$BRANCH
# the changes committed
svn ci -F svnmerge-commit-message.txt
# and your private branch deleted
svn rm svn+ssh://$RUSER@svn.gna.org/svn/relax/branches/$BRANCH
</source>
