From 6c7a4266410070d30f8f6bcdf9c9e67f3d6478e3 Mon Sep 17 00:00:00 2001 From: Andrey Andreev Date: Mon, 19 Jun 2017 11:33:58 +0300 Subject: [ci skip] 3.1.5 release --- user_guide_src/source/installation/upgrade_200.rst | 148 --------------------- 1 file changed, 148 deletions(-) delete mode 100644 user_guide_src/source/installation/upgrade_200.rst (limited to 'user_guide_src/source/installation/upgrade_200.rst') diff --git a/user_guide_src/source/installation/upgrade_200.rst b/user_guide_src/source/installation/upgrade_200.rst deleted file mode 100644 index 03b8ff4ac..000000000 --- a/user_guide_src/source/installation/upgrade_200.rst +++ /dev/null @@ -1,148 +0,0 @@ -############################# -Upgrading from 1.7.2 to 2.0.0 -############################# - -Before performing an update you should take your site offline by -replacing the index.php file with a static one. - -******************* -Update Instructions -******************* - -Step 1: Update your CodeIgniter files -===================================== - -Replace all files and directories in your "system" folder **except** -your application folder. - -.. note:: If you have any custom developed files in these folders please - make copies of them first. - -Step 2: Adjust get_dir_file_info() where necessary -===================================================== - -Version 2.0.0 brings a non-backwards compatible change to -get_dir_file_info() in the :doc:`File -Helper <../helpers/file_helper>`. Non-backwards compatible changes -are extremely rare in CodeIgniter, but this one we feel was warranted -due to how easy it was to create serious server performance issues. If -you *need* recursiveness where you are using this helper function, -change such instances, setting the second parameter, $top_level_only -to FALSE:: - - get_dir_file_info('/path/to/directory', FALSE); - -Step 3: Convert your Plugins to Helpers -======================================= - -2.0.0 gets rid of the "Plugin" system as their functionality was -identical to Helpers, but non-extensible. You will need to rename your -plugin files from filename_pi.php to filename_helper.php, move them to -your helpers folder, and change all instances of:: - - $this->load->plugin('foo'); - -to :: - - $this->load->helper('foo'); - - -Step 4: Update stored encrypted data -==================================== - -.. note:: If your application does not use the Encrypt library, does - not store Encrypted data permanently, or is on an environment that does - not support Mcrypt, you may skip this step. - -The Encrypt library has had a number of improvements, some for -encryption strength and some for performance, that has an unavoidable -consequence of making it no longer possible to decode encrypted data -produced by the original version of this library. To help with the -transition, a new method has been added, encode_from_legacy() that -will decode the data with the original algorithm and return a re-encoded -string using the improved methods. This will enable you to easily -replace stale encrypted data with fresh in your applications, either on -the fly or en masse. - -Please read :doc:`how to use this -method <../libraries/encrypt>` in the Encrypt library -documentation. - -Step 5: Remove loading calls for the compatibility helper. -========================================================== - -The compatibility helper has been removed from the CodeIgniter core. All -methods in it should be natively available in supported PHP versions. - -Step 6: Update Class extension -============================== - -All core classes are now prefixed with CI\_. Update Models and -Controllers to extend CI_Model and CI_Controller, respectively. - -Step 7: Update Parent Constructor calls -======================================= - -All native CodeIgniter classes now use the PHP 5 \__construct() -convention. Please update extended libraries to call -parent::\__construct(). - -Step 8: Move any core extensions to application/core -==================================================== - -Any extensions to core classes (e.g. MY_Controller.php) in your -application/libraries folder must be moved to the new -application/core folder. - -Step 9: Update your user guide -============================== - -Please replace your local copy of the user guide with the new version, -including the image files. - - -************ -Update Notes -************ - -Please refer to the :ref:`2.0.0 Change Log <2.0.0-changelog>` for full -details, but here are some of the larger changes that are more likely to -impact your code: - -- Scaffolding has been removed. -- The CAPTCHA plugin in now a :doc:`helper `. -- The JavaScript calendar plugin was removed. -- The *system/cache* and *system/logs* directories are now in the application - directory. -- The Validation class has been removed. Please see the - :doc:`Form Validation library ` -- "default" is now a reserved name. -- The xss_clean() function has moved to the :doc:`Security Class - `. -- do_xss_clean() now returns FALSE if the uploaded file fails XSS checks. -- The :doc:`Session Class ` requires now the use of an - encryption key set in the config file. -- The following deprecated Active Record functions have been removed: - ``orwhere``, ``orlike``, ``groupby``, ``orhaving``, ``orderby``, - ``getwhere``. -- ``_drop_database()`` and ``_create_database()`` functions have been removed - from the db utility drivers. -- The ``dohash()`` function of the :doc:`Security helper - ` - has been renamed to ``do_hash()`` for naming consistency. - -The config folder -================= - -The following files have been changed: - -- config.php -- database.php -- mimes.php -- routes.php -- user_agents.php - -The following files have been added: - -- foreign_chars.php -- profiler.php \ No newline at end of file -- cgit v1.2.3-24-g4f1b
