<h2><a name="preparations">2. Preparations</a></h2>
<ol>
<li>Install required software (notice: git is named git-core on Debian/oldstable):
<pre>
<b># apt-get install git git-buildpackage dpkg-dev</b>
</pre>
</li>
<li>Set environment variables (e.g. through your ~/.bashrc or ~/.zshrc) for devscripts (gbp dch):
<pre>
<b>export DEBEMAIL=$mailaddress
export DEBFULLNAME=$yourname</b>
</pre>
</li>
<li>Set user name and email address for git (drop the --global option to use configuration per-repo basis):
<pre>
<b>% git config --global user.name "$yourname"
% git config --global user.email "$mailaddress"</b>
</pre>
</li>
<li><a name="checkout">Checkout</a> repository (anonymous):
<pre>
<b>% git clone git://git.debian.org/git/kernel/initramfs-tools.git
% cd initramfs-tools</b>
</pre>
</li>
<li>Checkout repository (with developer access):
<pre>
<b>% git clone ssh://<code><i>$username</i></code>@git.debian.org/git/kernel/initramfs-tools.git
% cd initramfs-tools</b>
</pre>
</li>
</ol>

<h2><a name="workflow">3. Workflow for daily work</a></h2>
<h3><a name="newfeature">3.1 Implement new features</a></h3>
<ol>
<li>Checkout new branch and switch to it:
<pre>
<b>% git checkout -b <code><i>$username</i></code>/short-descr-of-new-feature</b>
</pre>
</li>
<li>Hack and commit work:
<pre>
<b>% $EDITOR $somefile
% git add $somefile
% git commit -s</b>
</pre>
<b>NOTE:</b> Use 'Closes: #BUGID' for closing a bugreport and 'Thanks: Fullname
<<code><i>mailaddress</i></code>>' for giving credits in your commit message. gbp dch will use
this information for generating the changelog using the --meta option later
on.
</li>
<li>Finally push your branch to alioth:
<pre>
<b>% git push origin <code><i>$username</i></code>/short-descr-of-new-feature</b>
</pre>
</li>
</ol>
<h3><a name="merge">3.2 Merge branches</a></h3>
<ol>
<li>Switch to the branch you want to merge:
<pre>
<b>% git checkout <code><i>$username</i></code>/new-feature</b>
</pre>
</li>
<li>Rebase to master:
<pre>
<b>% git rebase master</b>
</pre>
</li>
<li>Switch to master branch and merge:
<pre>
<b>% git checkout master
% git merge <code><i>$username</i></code>/new-feature</b>
</pre>
</li>
<li>Push:
<pre>
<b>% git push</b>
</pre>
</li>
<li>After branch is merged delete branch on server and locally:
<pre>
<b>% git push origin :<code><i>$username</i></code>/short-descr-of-new-feature
% git branch -d <code><i>$username</i></code>/short-descr-of-new-feature</b>
</pre>
</li>
<li>If a branch is removed from the server it will stay locally. You can get of
any stale remote branches locally by executing:
<pre>
<b>% git remote prune origin</b>
</pre>
</li>
</ol>
<h3><a name="test">3.3 Test specific branch</a></h3>
<ol>
<li>Checkout a specific branch iff branch is not already present locally:
<pre>
<b>% git checkout -b somename/short-descr-of-new-feature origin/somename/short-descr-of-new-feature</b>
</pre>
</li>
<li>Checkout a specific branch iff branch is already present locally:
<pre>
<b>% git checkout -b somename/short-descr-of-new-feature</b>
</pre>
</li>
<li>Adjust debian/changelog accordingly:
<pre>
<b>% gbp dch --debian-branch="$(git branch | awk -F\*\ '/^* / { print $2}' )" \
--since="v$(dpkg-parsechangelog | awk '/^Version:/ {print $2}')" -S --id-length=7 --meta --multimaint-merge</b>
</pre>
</li>
<li>Build package:
<pre>
<b>% gbp buildpackage --git-ignore-new --git-debian-branch="$(git branch | awk -F\*\ '/^* / { print $2}' )" --post-clean</b>
</pre>
</li>
</ol>
<div class="right"><a href="#toc">^</a></div>
<hr />
<h3><a name="snapshot">3.4 Build snapshot version</a></h3>
<ol>
<li>Adjust debian/changelog accordingly:
<pre>
<b>% gbp dch --debian-branch="$(git branch | awk -F\*\ '/^* / { print $2}' )" \
--since="v$(dpkg-parsechangelog | awk '/^Version:/ {print $2}')" -S --id-length=7 --meta --multimaint-merge</b>
</pre>
</li>
<li>Build package:
<pre>
<b>% gbp buildpackage --git-debian-branch="$(git branch | awk -F\*\ '/^* / { print $2}' )" --post-clean [-us -uc]</b>
</pre>
</li>
</ol>
<div class="right"><a href="#toc">^</a></div>

<b>NOTE:</b> we do not use history based sorting for the changelog entries but
sort them by author.
