60<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
61
62
63
64<h2>Step 1: Update your CodeIgniter files</h2>
65
66<p>Replace these files and directories in your "system" folder with the new versions:</p>
67
68<ul>
69
70<li><dfn>system/codeigniter</dfn></li>
71<li><dfn>system/database</dfn></li>
72<li><dfn>system/helpers</dfn></li>
73<li><dfn>system/language</dfn></li>
74<li><dfn>system/libraries</dfn></li>
75</ul>
76
77<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
78
79<h2>Step 2: Adjust get_dir_file_info() where necessary</h2>

Derek Jones8917af72010-03-05 12:41:45 -0600[diff] [blame^]81<p>Version 2.0.0 brings a non-backwards compatible change to <kbd>get_dir_file_info()</kbd> in the <a href="../helpers/file_helper.html">File Helper</a>. Non-backwards compatible changes are extremely rare
Derek Jones788b00f2009-11-27 18:00:20 +0000[diff] [blame]82 in CodeIgniter, but this one we feel was warranted due to how easy it was to create serious server performance issues. If you <em>need</em>
83 recursiveness where you are using this helper function, change such instances, setting the second parameter, <kbd>$top_level_only</kbd> to FALSE:</p>
84
85<code>get_dir_file_info('/path/to/directory', <kbd>FALSE</kbd>);</code>
86
87<h2>Step 3: Update your user guide</h2>
88<p>Please replace your local copy of the user guide with the new version, including the image files.</p>
