<!-- ==================== CLASS DESCRIPTION ==================== -->
<h1 class="epydoc">Class IsoImage</h1><p class="nomargin-top"><span class="codelink"><a href="CedarBackup2.writers.util-pysrc.html#IsoImage">source code</a></span></p>
<pre class="base-tree">

<strong class="uidshort">IsoImage</strong>
</pre>
<hr />
<p>Represents an ISO filesystem image.</p>
<h1 class="heading">Summary</h1>
<p>This object represents an ISO 9660 filesystem image. It is
implemented in terms of the <code>mkisofs</code> program, which has
been ported to many operating systems and platforms. A "sensible
subset" of the <code>mkisofs</code> functionality is made
available through the public interface, allowing callers to set a
variety of basic options such as publisher id, application id, etc. as
well as specify exactly which files and directories they want included
in their image.</p>
<p>By default, the image is created using the Rock Ridge protocol
(using the <code>-r</code> option to <code>mkisofs</code>) because Rock
Ridge discs are generally more useful on UN*X filesystems than standard
ISO 9660 images. However, callers can fall back to the default
<code>mkisofs</code> functionality by setting the
<code>useRockRidge</code> instance variable to <code>False</code>.
Note, however, that this option is not well-tested.</p>
<h1 class="heading">Where Files and Directories are Placed in the Image</h1>
<p>Although this class is implemented in terms of the
<code>mkisofs</code> program, its standard "image contents"
semantics are slightly different than the original <code>mkisofs</code>
semantics. The difference is that files and directories are added to
the image with some additional information about their source directory
kept intact.</p>
<p>As an example, suppose you add the file <code>/etc/profile</code> to
your image and you do not configure a graft point. The file
<code>/profile</code> will be created in the image. The behavior for
directories is similar. For instance, suppose that you add
<code>/etc/X11</code> to the image and do not configure a graft point.
In this case, the directory <code>/X11</code> will be created in the
image, even if the original <code>/etc/X11</code> directory is empty.
<i>This behavior differs from the standard <code>mkisofs</code>
behavior!</i></p>
<p>If a graft point is configured, it will be used to modify the point
at which a file or directory is added into an image. Using the
examples from above, let's assume you set a graft point of
<code>base</code> when adding <code>/etc/profile</code> and
<code>/etc/X11</code> to your image. In this case, the file
<code>/base/profile</code> and the directory <code>/base/X11</code>
would be added to the image.</p>
<p>I feel that this behavior is more consistent than the original
<code>mkisofs</code> behavior. However, to be fair, it is not quite as
flexible, and some users might not like it. For this reason, the
<code>contentsOnly</code> parameter to the <a
href="CedarBackup2.writers.util.IsoImage-class.html#addEntry"
class="link">addEntry</a> method can be used to revert to the original
behavior if desired.</p>

<ul class="nomargin-top">
<li>
Things get <i>odd</i> if you try to add a directory to an image
that will be written to a multisession disc, and the same directory
already exists in an earlier session on that disc. Not all of the
data gets written. You really wouldn't want to do this anyway, I
guess.
</li>
<li>
An exception will be thrown if the path has already been added to
the image, unless the <code>override</code> parameter is set to
<code>True</code>.
</li>
<li>
The method <code>graftPoints</code> parameter overrides the
object-wide instance variable. If neither the method parameter or
object-wide value is set, the path will be written at the image
root. The graft point behavior is determined by the value which is
in effect <i>at the time this method is called</i>, so you
<i>must</i> set the object-wide value before calling this method
for the first time, or your image may not be consistent.
</li>
<li>
You <i>cannot</i> use the local <code>graftPoint</code> parameter
to "turn off" an object-wide instance variable by setting
it to <code>None</code>. Python's default argument functionality
buys us a lot, but it can't make this method psychic. :)
