<h1>Patching Guide</h1>
<p>This explains how to debrand/patch a package for the Rocky Linux distribution.</p>
<h2 id="general-instructions">General Instructions<a class="headerlink" href="#general-instructions" title="Permanent link">&para;</a></h2>
<ul>
<li>First, identify the files in the package that need to be changed. They could be text files, image files, or others. You can identify the file(s) by digging into git.centos.org/rpms/PACKAGE/</li>
<li>Develop replacements for these files, but with Rocky branding placed instead. Diff/patch files may be needed as well for certain types of text, depends on the content being replaced.</li>
<li>Replacement files go under https://git.rockylinux.org/patch/PACKAGE/ROCKY/_supporting/</li>
<li>Config file (specifying how to apply the patches) goes in https://git.rockylinux.org/patch/PACKAGE/ROCKY/CFG/*.cfg</li>
<li>Note: Use spaces, not tabs.</li>
<li>When srpmproc goes to import the package to Rocky, it will see the work done in https://git.rockylinux.org/patch/PACKAGE , and apply the stored patches by reading the config file(s) under ROCKY/CFG/*.cfg</li>
</ul>
<h2 id="the-patch-config-language">The Patch Config Language<a class="headerlink" href="#the-patch-config-language" title="Permanent link">&para;</a></h2>
<p>Patching uses simple proto3 config files. The general format is:
<div class="highlight"><pre><span></span><code>Action {
file: &quot;OriginalFile&quot;
with_file: &quot;ROCKY/_supporting/RockyReplaceFile&quot;
}
</code></pre></div></p>
<p>A simple example to replace a file:
<div class="highlight"><pre><span></span><code>replace {
file: &quot;redhatlogo.png&quot;
with_file: &quot;ROCKY/_supporting/rockylogo.png&quot;
}
</code></pre></div></p>
<p>The file "redhatlogo.png" would be located in under SOURCES/ in the project's Git repository (and SRPM).</p>
<h2 id="patch-configuration-options">Patch configuration options<a class="headerlink" href="#patch-configuration-options" title="Permanent link">&para;</a></h2>
<ul>
<li><code>add</code>: Adds a file to the sources using the <code>file</code> or <code>lookaside</code> directive</li>
<li><code>delete</code>: Deletes a file from the sources using the <code>file</code> directive</li>
<li><code>replace</code>: Replaces a file from the sources using the <code>file</code> and <code>with_file</code> directives</li>
<li><code>patch</code>: Performs a patch based on the diff provided in the <code>file</code> directive (generated using <code>git diff</code>)</li>
<li><code>spec_change</code>: Allows for spec files to be modified</li>
<li><code>search_and_replace</code>: Performs a search and replace on a given text for the spec file using the <code>any/starts_with/ends_with</code> (true|false), <code>find</code> (string to find), <code>replace</code> (replacement string), and <code>n</code> (integar, <code>-1</code> for any) directives.</li>
<li><code>file</code>: A file can be added to the spec file using the <code>name</code> directive to define the file name, the <code>type</code> directive (such as <code>patch</code>) and then an <code>add</code> option that is <code>true</code> or <code>false</code><ul>
<li>When <code>patch</code> is used, the following options are available:</li>
<li><code>add_to_prep</code> (true|false)</li>
<li><code>n_path: N</code> can be specified to add <code>%patchX -pN</code> lines into <code>%prep</code> assuming the rpm does not use <code>%autosetup</code></li>
</ul>
</li>
<li><code>append</code>: Appends to a given <code>field</code>, such as <code>Release</code> with a <code>value</code> directive</li>
<li><code>changelog</code>: Modifies the change log using <code>author_name</code>, <code>author_email</code>, and <code>message</code> directives</li>
</ul>
<p>Patch configuration structure:</p>
<div class="highlight"><pre><span></span><code>.
└── ROCKY
├── CFG
└── _supporting
</code></pre></div>
<h2 id="case-study-nginx">Case Study: Nginx<a class="headerlink" href="#case-study-nginx" title="Permanent link">&para;</a></h2>
<p><strong>(note: all example data here is currently in the staging/ area of Rocky Linux Git. We will update it when the projects are moved to the production area)</strong></p>
<p>Let's go over an example debrand, featuring the Nginx web server package.</p>
<p>The source repository is located here: <strong>https://git.centos.org/rpms/nginx</strong></p>
<p>If we browse one of the c8-* branches, we see under SOURCES/ that there is definitely some content that needs to be debranded:</p>
<div class="highlight"><pre><span></span><code>404.html
50x.html
index.html
poweredby.png (binary file in dist-git, referred to in .nginx.metadata)
</code></pre></div>
<p>These files all refer to Red Hat inc., and must be replaced before they make it to Rocky Linux.</p>
<p><strong>1: Come up with the patches:</strong> Each of these files has a Rocky Linux counterpart, and they must be created. <strong>Some of this should be done by the Design Team, especially logo work (#Design on chat)</strong></p>
<p><strong>2: Commit patches to the matching patch/PROJECT Git repository</strong> : For example, Nginx patches are located here: <strong>https://git.rockylinux.org/staging/patch/nginx</strong> (staging/ prefix is currently used until our production repos are set up)</p>
<p><strong>3: Develop a matching config file:</strong> Our example Nginx has this here: <strong>https://git.rockylinux.org/staging/patch/nginx/-/blob/main/ROCKY/CFG/pages.cfg</strong></p>
<p>It looks like this:
<div class="highlight"><pre><span></span><code>replace {
file: &quot;index.html&quot;
with_file: &quot;ROCKY/_supporting/index.html&quot;
}
replace {
file: &quot;404.html&quot;
with_file: &quot;ROCKY/_supporting/404.html&quot;
}
replace {
file: &quot;50x.html&quot;
with_file: &quot;ROCKY/_supporting/50x.html&quot;
}
replace {
file: &quot;poweredby.png&quot;
with_file: &quot;ROCKY/_supporting/poweredby.png&quot;
}
</code></pre></div></p>
<p><strong>4: Test the import:</strong> Now, when the upstream is imported, we can check the main Rocky <strong>nginx</strong> repository and ensure our updates were successful: <strong>https://git.rockylinux.org/staging/rpms/nginx/</strong> (again, staging/ group is used only for now)</p>
<p><strong>5: You're Done!</strong> Great! Now do the next one... ;-)</p>
<h2 id="more-debrand-config-language">More Debrand Config Language<a class="headerlink" href="#more-debrand-config-language" title="Permanent link">&para;</a></h2>
<p>The Nginx example showed just the <strong>replace</strong> directive, but there are several more available. They are <strong>add</strong>, <strong>patch</strong>, and <strong>delete.</strong></p>
<p>Here they are, with examples:</p>
<div class="highlight"><pre><span></span><code># Add a file to the project (file is added to SOURCES/ folder )
add {
file: &quot;ROCKY/_supporting/add_me.txt&quot;
}
# Apply a .patch file (generated using the Linux &quot;patch&quot; utility)
patch {
file: &quot;ROCKY/_supporting/002-test-html.patch&quot;
}
# Delete a file from the source project
delete {
file: &quot;SOURCES/dontneed.txt&quot;
}
</code></pre></div>
<p>And the .patch file example looks like this:
<div class="highlight"><pre><span></span><code>diff --git a/SOURCES/test.html b/SOURCES/test.html
index 8d91ffd..3f76c3b 100644
--- a/SOURCES/test.html
+++ b/SOURCES/test.html
@@ -1,6 +1,6 @@
&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;body&gt;
- &lt;h1&gt;Replace me&lt;/h1&gt;
+ &lt;h1&gt;Replace I did!&lt;/h1&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre></div></p>
<p>It also supports spec file changes, as it may be necessary. For example, from the anaconda debrand patch repo.</p>
<div class="highlight"><pre><span></span><code>add {
file: &quot;ROCKY/_supporting/0002-Rocky-disable-cdn-radiobutton.patch&quot;
}
spec_change {
# Adds a Patch line with the file name as listed above
file {
name: &quot;0002-Rocky-disable-cdn-radiobutton.patch&quot;
type: Patch
add: true
}
# Appends to the end of a field&#39;s line, in this case the Release field gets .rocky
append {
field: &quot;Release&quot;
value: &quot;.rocky&quot;
}
# Adds to the change log properly
changelog {
author_name: &quot;Mustafa Gezen&quot;
author_email: &quot;mustafa@rockylinux.org&quot;
message: &quot;Disable CDN and add .rocky to Release&quot;
}
}
</code></pre></div>
<p>At the end, the spec file should be changed.</p>
<div class="highlight"><pre><span></span><code>Summary: Graphical system installer
