<h1>Developer Guide<a class="headerlink" href="#developer-guide" title="Permalink to this headline">¶</a></h1>
|
||
<p>When looking at a non-trivial codebase for the first time, it’s very difficult to understand
|
||
anything of it until you get the “Big Picture”. This page is meant to, hopefully, make you get
|
||
dupeGuru’s big picture.</p>
|
||
<div class="section" id="branches-and-tags">
|
||
<h2>Branches and tags<a class="headerlink" href="#branches-and-tags" title="Permalink to this headline">¶</a></h2>
|
||
<p>The git repo has one main branch, <code class="docutils literal notranslate"><span class="pre">master</span></code>. It represents the latest “stable development commit”,
|
||
that is, the latest commit that doesn’t include in-progress features. This branch should always
|
||
be buildable, <code class="docutils literal notranslate"><span class="pre">tox</span></code> should always run without errors on it.</p>
|
||
<p>When a feature/bugfix has an atomicity of a single commit, it’s alright to commit right into
|
||
<code class="docutils literal notranslate"><span class="pre">master</span></code>. However, if a feature/bugfix needs more than a commit, it should live in a separate
|
||
topic branch until it’s ready.</p>
|
||
<p>Every release is tagged with the version number. For example, there’s a <code class="docutils literal notranslate"><span class="pre">2.8.2</span></code> tag for the
|
||
v2.8.2 release.</p>
|
||
</div>
|
||
<div class="section" id="model-view-controller-nope">
|
||
<h2>Model/View/Controller… nope!<a class="headerlink" href="#model-view-controller-nope" title="Permalink to this headline">¶</a></h2>
|
||
<p>dupeGuru’s codebase has quite a few design flaws. The Model, View and Controller roles are filled by
|
||
different classes, scattered around. If you’re aware of that, it might help you to understand what
|
||
the heck is going on.</p>
|
||
<p>The central piece of dupeGuru is <a class="reference internal" href="core/app.html#core.app.DupeGuru" title="core.app.DupeGuru"><code class="xref py py-class docutils literal notranslate"><span class="pre">core.app.DupeGuru</span></code></a>. It’s the only
|
||
interface to the python’s code for the GUI code. A duplicate scan is started with
|
||
<a class="reference internal" href="core/app.html#core.app.DupeGuru.start_scanning" title="core.app.DupeGuru.start_scanning"><code class="xref py py-meth docutils literal notranslate"><span class="pre">core.app.DupeGuru.start_scanning()</span></code></a>, directories are added through
|
||
<a class="reference internal" href="core/app.html#core.app.DupeGuru.add_directory" title="core.app.DupeGuru.add_directory"><code class="xref py py-meth docutils literal notranslate"><span class="pre">core.app.DupeGuru.add_directory()</span></code></a>, etc..</p>
|
||
<p>A lot of functionalities of the App are implemented in the platform-specific subclasses of
|
||
<a class="reference internal" href="core/app.html#core.app.DupeGuru" title="core.app.DupeGuru"><code class="xref py py-class docutils literal notranslate"><span class="pre">core.app.DupeGuru</span></code></a>, like <code class="docutils literal notranslate"><span class="pre">DupeGuru</span></code> in <code class="docutils literal notranslate"><span class="pre">cocoa/inter/app.py</span></code>, or the <code class="docutils literal notranslate"><span class="pre">DupeGuru</span></code> class
|
||
in <code class="docutils literal notranslate"><span class="pre">qt/base/app.py</span></code>. For example, when performing “Remove Selected From Results”,
|
||
<code class="docutils literal notranslate"><span class="pre">RemoveSelected()</span></code> on the cocoa side, and <code class="docutils literal notranslate"><span class="pre">remove_duplicates()</span></code> on the PyQt side, are
|
||
respectively called to perform the thing.</p>

<div class="section" id="jobs">

<span id="id1"></span><h2>Jobs<a class="headerlink" href="#jobs" title="Permalink to this headline">¶</a></h2>
|
||
<p>A lot of operations in dupeGuru take a significant amount of time. This is why there’s a generalized
|
||
threaded job mechanism built-in <a class="reference internal" href="core/app.html#core.app.DupeGuru" title="core.app.DupeGuru"><code class="xref py py-class docutils literal notranslate"><span class="pre">DupeGuru</span></code></a>. First, <a class="reference internal" href="core/app.html#core.app.DupeGuru" title="core.app.DupeGuru"><code class="xref py py-class docutils literal notranslate"><span class="pre">DupeGuru</span></code></a> has
|
||
a <code class="docutils literal notranslate"><span class="pre">progress</span></code> member which is an instance of
|
||
<a class="reference internal" href="hscommon/jobprogress/performer.html#hscommon.jobprogress.performer.ThreadedJobPerformer" title="hscommon.jobprogress.performer.ThreadedJobPerformer"><code class="xref py py-class docutils literal notranslate"><span class="pre">ThreadedJobPerformer</span></code></a>. It lets the GUI code know of the progress
|
||
of the current threaded job. When <a class="reference internal" href="core/app.html#core.app.DupeGuru" title="core.app.DupeGuru"><code class="xref py py-class docutils literal notranslate"><span class="pre">DupeGuru</span></code></a> needs to start a job, it calls
|
||
<code class="docutils literal notranslate"><span class="pre">_start_job()</span></code> and the platform specific subclass deals with the details of starting the job.</p>

<h2>Core principles<a class="headerlink" href="#core-principles" title="Permalink to this headline">¶</a></h2>
|

<p>The core of the duplicate matching takes place (for SE and ME, not PE) in <a class="reference internal" href="core/engine.html#module-core.engine" title="core.engine"><code class="xref py py-mod docutils literal notranslate"><span class="pre">core.engine</span></code></a>.
|
||
There’s <a class="reference internal" href="core/engine.html#core.engine.getmatches" title="core.engine.getmatches"><code class="xref py py-func docutils literal notranslate"><span class="pre">core.engine.getmatches()</span></code></a> which take a list of <a class="reference internal" href="core/fs.html#core.fs.File" title="core.fs.File"><code class="xref py py-class docutils literal notranslate"><span class="pre">core.fs.File</span></code></a> instances and
|
||
return a list of <code class="docutils literal notranslate"><span class="pre">(firstfile,</span> <span class="pre">secondfile,</span> <span class="pre">match_percentage)</span></code> matches. Then, there’s
|
||
<a class="reference internal" href="core/engine.html#core.engine.get_groups" title="core.engine.get_groups"><code class="xref py py-func docutils literal notranslate"><span class="pre">core.engine.get_groups()</span></code></a> which takes a list of matches and returns a list of

||
<a class="reference internal" href="core/engine.html#core.engine.Group" title="core.engine.Group"><code class="xref py py-class docutils literal notranslate"><span class="pre">Group</span></code></a> instances (a <a class="reference internal" href="core/engine.html#core.engine.Group" title="core.engine.Group"><code class="xref py py-class docutils literal notranslate"><span class="pre">Group</span></code></a> is basically a list of <a class="reference internal" href="core/fs.html#core.fs.File" title="core.fs.File"><code class="xref py py-class docutils literal notranslate"><span class="pre">File</span></code></a> matching
|
||
together).</p>
|
||
<p>When a scan is over, the final result (the list of groups from <a class="reference internal" href="core/engine.html#core.engine.get_groups" title="core.engine.get_groups"><code class="xref py py-func docutils literal notranslate"><span class="pre">get_groups()</span></code></a>) is placed into
|
||
<a class="reference internal" href="core/app.html#core.app.DupeGuru.results" title="core.app.DupeGuru.results"><code class="xref py py-attr docutils literal notranslate"><span class="pre">core.app.DupeGuru.results</span></code></a>, which is a <a class="reference internal" href="core/results.html#core.results.Results" title="core.results.Results"><code class="xref py py-class docutils literal notranslate"><span class="pre">core.results.Results</span></code></a> instance. The
|
||
<a class="reference internal" href="core/results.html#core.results.Results" title="core.results.Results"><code class="xref py py-class docutils literal notranslate"><span class="pre">Results</span></code></a> instance is where all the dupe marking, sorting, removing, power marking, etc.
|
||
takes place.</p>
