1 This files describes API changes in core libraries and APIs,
2 information provided here is intended especially for developers.
6 * Use new core_component::* plugin listing and component normalisation methods.
7 * Use core_text::* instead of textlib:: and also core_collator::* instead of collatorlib::*.
8 * Use new function moodleform::mock_submit() to simulate form submission in unit tests (backported).
9 * get_context_instance() is deprecated, please use use context_xxxx::instance().
10 * get_context_instance_by_id() is deprecated, please use context::instance_by_id($id).
11 * load_temp_role() and remove_temp_roles() can not be used any more.
12 * get_system_context() is deprecated, please use context_system::instance().
13 * get_parent_contexts() is deprecated, please use $context->get_parent_context_ids().
14 * get_parent_contextid() is deprecated, please use $context->get_parent_context().
15 * get_child_contexts() is deprecated, please use $context->get_child_contexts().
16 * create_contexts() is deprecated, please use context_helper::create_instances().
17 * cleanup_contexts() is deprecated, please use context_helper::cleanup_instances().
18 * build_context_path() is deprecated, please use context_helper::build_all_paths().
19 * rebuild_contexts() is deprecated, please use $context->reset_paths().
20 * preload_course_contexts() is deprecated, please use context_helper::preload_course().
21 * context_moved() is deprecated, please use context::update_moved().
22 * context_instance_preload() is deprecated, please use context_helper::preload_from_record().
26 * New get_course() function for use when obtaining the course record from database. Will
27 reuse existing $COURSE or $SITE globals if possible to improve performance.
31 * The database drivers (moodle_database and subclasses) aren't using anymore the ::columns property
32 for caching database metadata. MUC (databasemeta) is used instead. Any custom DB driver should
33 apply for that change.
34 * The cron output has been changed to include time and memory usage (see cron_trace_time_and_memory()),
35 so any custom utility relying on the old output may require modification.
36 * Function get_max_file_sizes now returns an option for (for example) "Course limit (500MB)" or
37 "Site limit (200MB)" when appropriate with the option set to 0. This function no longer returns
38 an option for 0 bytes. Existing code that was replacing the 0 option in the return
39 from this function with a more sensible message, can now use the return from this function directly.
40 * Functions responsible for output in course/lib.php are deprecated, the code is moved to
41 appropriate renderers: print_section(), print_section_add_menus(), get_print_section_cm_text(),
42 make_editing_buttons()
43 See functions' phpdocs in lib/deprecatedlib.php
44 * Function get_print_section_cm_text() is deprecated, replaced with methods in cm_info
45 * zip_packer may create empty zip archives, there is a new option to ignore
46 problematic files when creating archive
47 * The function delete_course_module was deprecated and has been replaced with
48 course_delete_module. The reason for this was because the function delete_course_module
49 only partially deletes data, so wherever it was called extra code was needed to
50 perform the whole deletion process. The function course_delete_module now takes care
52 * curl::setopt() does not accept constant values any more. As it never worked properly,
53 we decided to make the type check stricter. Now, the keys of the array pass must be a string
54 corresponding to the curl constant name.
55 * Function get_users_listing now return list of users except guest and deleted users. Previously
56 deleted users were excluded by get_users_listing. As guest user is not expected while browsing users,
57 and not included in get_user function, it will not be returned by get_users_listing.
58 * The add_* functions in course/dnduploadlib.php have been deprecated. Plugins should be using the
59 MODNAME_dndupload_register callback instead.
60 * The signature of the add() method of classes implementing the parentable_part_of_admin_tree
61 interface (such as admin_category) has been extended. The new parameter allows the caller
62 to prepend the new node before an existing sibling in the admin tree.
63 * condition_info:get_condition_user_fields($formatoptions) now accepts the optional
64 param $formatoptions, that will determine if the field names are processed by
65 format_string() with the passed options.
66 * remove all references to $CFG->gdversion, GD PHP extension is now required
67 * Formslib will now throw a developer warning if a PARAM_ type hasn't been set for elements which
68 need it. Please set PARAM_RAW explicitly if you do not want any cleaning.
69 * Functions responsible for managing and accessing course categories are moved to class coursecat
70 in lib/coursecatlib.php, functions responsible for rendering courses and categories lists are
71 moved to course/renderer.php. The following global functions are deprecated: make_categories_list(),
72 category_delete_move(), category_delete_full(), move_category(), course_category_hide(),
73 course_category_show(), get_course_category(), create_course_category(), get_all_subcategories(),
74 get_child_categories(), get_categories(), print_my_moodle(), print_remote_course(),
75 print_remote_host(), print_whole_category_list(), print_category_info(), get_course_category_tree(),
76 print_courses(), print_course(), get_category_courses_array(), get_category_courses_array_recursively(),
77 get_courses_wmanagers()
78 See http://docs.moodle.org/dev/Courses_lists_upgrade_to_2.5
79 * $core_renderer->block_move_target() changed to support more verbose move-block-here descriptions.
80 * Additional (optional) param $onlyactive has been added to get_enrolled_users, count_enrolled_users
81 functions to get information for only active (excluding suspended enrolments) users. Included two
82 helper functions extract_suspended_users, get_suspended_userids to extract suspended user information.
83 * The plugin_manager class now provides two new helper methods for getting information
84 about known plugins: get_plugins_of_type() and get_subplugins_of_plugin().
85 * The get_uninstall_url() method of all subclasses of plugininfo_base class is now expected
86 to always return moodle_url. Subclasses can use the new method is_uninstall_allowed()
87 to control the availability of the 'Uninstall' link at the Plugins overview page (previously
88 they would do it by get_uninstall_url() returning null). By default, URL to a new general plugin
89 uninstall tool is returned. Unless the plugin type needs extra steps that can't be handled by
90 plugininfo_xxx::uninstall() method or xmldb_xxx_uninstall() function, this default URL should
91 satisfy all plugin types.
94 * $DB->sql_empty() is deprecated, you have to use sql parameters with empty values instead,
95 please note hardcoding of empty strings in SQL queries breaks execution in Oracle database.
96 * Indexes must not be defined on the same columns as keys, this is now reported as fatal problem.
97 Please note that internally we create indexes instead of foreign keys.
100 * M.util.help_icon has been deprecated. Code should be updated to use moodle-core-popuphelp
101 instead. To do so, remove any existing JS calls to M.util.help_icon from your PHP and ensure
102 that your help link is placed in a span which has the class 'helplink'.
106 * Pagelib: Numerous deprecated functions were removed as classes page_base, page_course
107 and page_generic_activity.
108 * use $CFG->googlemapkey3 instead of removed $CFG->googlemapkey and migrate to Google Maps API V3
109 * Function settings_navigation::add_course_editing_links() is completely removed
110 * function global_navigation::format_display_course_content() is removed completely (the
111 functionality is moved to course format class)
112 * in the function global_navigation::load_generic_course_sections() the argument $courseformat is
114 * New component and itemid columns in groups_members table - this allows plugin to create protected
115 group memberships using 'xx_yy_allow_group_member_remove' callback and there is also a new restore
116 callback 'xx_yy_restore_group_member()'.
117 * New general role assignment restore plugin callback 'xx_yy_restore_role_assignment()'.
118 * functions get_generic_section_name(), get_all_sections(), add_mod_to_section(), get_all_mods()
119 are deprecated. See their phpdocs in lib/deprecatedlib.php on how to replace them
122 * moodle-enrol-notification has been renamed to moodle-core-notification
123 * YUI2 code must now use 2in3, see http://yuilibrary.com/yui/docs/yui/yui-yui2.html
124 * M.util.init_select_autosubmit() and M.util.init_url_select() have been deprecated. Code using this should be updated
125 to use moodle-core-formautosubmit
127 Unit testing changes:
128 * output debugging() is not sent to standard output any more,
129 use $this->assertDebuggingCalled(), $this->assertDebuggingNotCalled(),
130 $this->getDebuggingMessages() or $this->assertResetDebugging() instead.
134 Database layer changes:
135 * objects are not allowed in paramters of DML functions, use explicit casting to strings if necessary
138 * DDL and DML methods which were deprecated in 2.0 have now been removed, they will no longer produce
139 debug messages and will produce fatal errors
143 * send_stored_file() has changed its interface
144 * deleted several resourcelib_embed_* functions from resourcelib.php
148 removed unused libraries:
149 * odbc, base32, CodeSniffer, overlib, apd profiling, kses, Smarty, PEAR Console, swfobject, cssshover.htc, md5.js
152 * new admin/tool plugin type
153 * new context API - old API is still available
154 * deleted users do not have context any more
155 * removed global search
