First, do a backup of your databases, and of your application files (modules, configuration etc.).

As usual, you must remove every files into the temp/yourapp/ directory. You have also to delete the temp/yourapp-cli/ directory and the temp/yourapp-scripts/ directory, they are not used anymore.

This file should use now jApp::initPaths() instead of defining JELIX_APP_* constants. You can access now to every path using the jApp object. JELIX_APP_* constants are generated for you automatically, to keep compatibility with modules not fully compatible with Jelix 1.3. However, it is highly recommanded to replace these JELIX_APP_* constants in theses modules, because future version of Jelix won't support anymore these constants.

Your application.init.php should contain this kind of code:

$appPath = dirname (__FILE__).'/';
require ($appPath.'../lib/jelix/init.php');

jApp::initPaths(
    $appPath
    //$appPath.'www/',
    //$appPath.'var/',
    //$appPath.'var/log/',
    //$appPath.'var/config/',
    //$appPath.'scripts/'
);
jApp::setTempBasePath(realpath($appPath.'../temp/testapp/').'/');

You can remove application-cli.init.php and jelix-scripts.init.php, they are useless now. If you have command line scripts into the scripts/ directory of your application, replace the include instruction for application-cli.init.php, by an include instruction for application.init.php.

• If you have activated minification of js and css files in your html responses, it won't work anymore because the configuration has changed. Some options have dispeared, the directory www/cache/minify is not used anymore, and a minify.php script should be installed into www/.
• you can add a tests/runtests.php script into your app directory, copied from lib/jelix-scripts/templates/tests/. It allows you to develop and run tests using phpunit.

• update sources of vendor's modules that you have installed, with version compatible with Jelix 1.3.
• For your own modules:
  • As indicated above, replace the use of JELIX_APP_* constants by the use of jApp.
  • In module.xml files, indicate that the module is compatible with Jelix 1.3 (change the attributes maxversion). Example :

        <jelix minversion="1.2" maxversion="1.3.*"/>

After all these modifications, you should run your installer.php script. The jelix module will change some things:

• in your configuration
• will create a new profiles.ini.php, storing content of dbprofils.ini.php, cache.ini.php, jkvdbprofiles.ini.php. Theses files will be removed.
• will create a new cmd.php in the root of your application, to launch commands of jelix-script

The module jacl2db will update your database, if you use this module.
