1 This files describes API changes in core libraries and APIs,
2 information provided here is intended especially for developers.
6 * Use new methods from core_component class instead of get_core_subsystems(), get_plugin_types(),
7 get_plugin_list(), get_plugin_list_with_class(), get_plugin_directory(), normalize_component()
8 and get_component_directory(). The names of the new methods are exactly the same, the only differences
9 are that core_component::get_plugin_types() now always returns full paths and
10 core_component::get_plugin_list() does not accept empty parameter any more.
11 * Use core_text::* instead of textlib:: and also core_collator::* instead of collatorlib::*.
12 * Use new function moodleform::mock_submit() to simulate form submission in unit tests (backported).
13 * New $CFG->localcachedir setting useful for cluster nodes. Admins have to update X-Sendfile aliases if used.
14 * MS SQL Server drivers are now using NVARCHAR(MAX) instead of NTEXT and VARBINARY(MAX) instead of IMAGE,
15 this change should be fully transparent and it should help significantly with add-on compatibility.
18 Various previously deprecated functions have now been altered to throw DEBUG_DEVELOPER debugging notices
19 and will be removed in a future release (target: 2.8), a summary follows:
22 * get_context_instance() -> context_xxxx::instance()

41 * rebuild_contexts() -> $context->reset_paths()
42 * get_user_courses_bycap() -> enrol_get_users_courses()
43 * get_courseid_from_context() -> $context->get_course_context(false)

82 * httpsrequired() -> $PAGE->https_required()
83 * detect_munged_arguments() -> clean_param([...], PARAM_FILE)
84 * mygroupid() -> groups_get_all_groups()
87 * moodle-core-notification has been deprecated with a recommendation of
88 using its subclasses instead. This is to allow for reduced page
89 transport costs. Current subclasses include:
98 * New get_course() function for use when obtaining the course record from database. Will
99 reuse existing $COURSE or $SITE globals if possible to improve performance.
103 * The database drivers (moodle_database and subclasses) aren't using anymore the ::columns property
104 for caching database metadata. MUC (databasemeta) is used instead. Any custom DB driver should
105 apply for that change.
106 * The cron output has been changed to include time and memory usage (see cron_trace_time_and_memory()),
107 so any custom utility relying on the old output may require modification.
108 * Function get_max_file_sizes now returns an option for (for example) "Course limit (500MB)" or
109 "Site limit (200MB)" when appropriate with the option set to 0. This function no longer returns
110 an option for 0 bytes. Existing code that was replacing the 0 option in the return
111 from this function with a more sensible message, can now use the return from this function directly.
112 * Functions responsible for output in course/lib.php are deprecated, the code is moved to
113 appropriate renderers: print_section(), print_section_add_menus(), get_print_section_cm_text(),
114 make_editing_buttons()
115 See functions' phpdocs in lib/deprecatedlib.php
116 * Function get_print_section_cm_text() is deprecated, replaced with methods in cm_info
117 * zip_packer may create empty zip archives, there is a new option to ignore
118 problematic files when creating archive
119 * The function delete_course_module was deprecated and has been replaced with
120 course_delete_module. The reason for this was because the function delete_course_module
121 only partially deletes data, so wherever it was called extra code was needed to
122 perform the whole deletion process. The function course_delete_module now takes care
123 of the whole process.
124 * curl::setopt() does not accept constant values any more. As it never worked properly,
125 we decided to make the type check stricter. Now, the keys of the array pass must be a string
126 corresponding to the curl constant name.
127 * Function get_users_listing now return list of users except guest and deleted users. Previously
128 deleted users were excluded by get_users_listing. As guest user is not expected while browsing users,
129 and not included in get_user function, it will not be returned by get_users_listing.
130 * The add_* functions in course/dnduploadlib.php have been deprecated. Plugins should be using the
131 MODNAME_dndupload_register callback instead.
132 * The signature of the add() method of classes implementing the parentable_part_of_admin_tree
133 interface (such as admin_category) has been extended. The new parameter allows the caller
134 to prepend the new node before an existing sibling in the admin tree.
135 * condition_info:get_condition_user_fields($formatoptions) now accepts the optional
136 param $formatoptions, that will determine if the field names are processed by
137 format_string() with the passed options.
138 * remove all references to $CFG->gdversion, GD PHP extension is now required
139 * Formslib will now throw a developer warning if a PARAM_ type hasn't been set for elements which
140 need it. Please set PARAM_RAW explicitly if you do not want any cleaning.
141 * Functions responsible for managing and accessing course categories are moved to class coursecat
142 in lib/coursecatlib.php, functions responsible for rendering courses and categories lists are
143 moved to course/renderer.php. The following global functions are deprecated: make_categories_list(),
144 category_delete_move(), category_delete_full(), move_category(), course_category_hide(),
145 course_category_show(), get_course_category(), create_course_category(), get_all_subcategories(),
146 get_child_categories(), get_categories(), print_my_moodle(), print_remote_course(),
147 print_remote_host(), print_whole_category_list(), print_category_info(), get_course_category_tree(),
148 print_courses(), print_course(), get_category_courses_array(), get_category_courses_array_recursively(),
149 get_courses_wmanagers()
150 See http://docs.moodle.org/dev/Courses_lists_upgrade_to_2.5
151 * $core_renderer->block_move_target() changed to support more verbose move-block-here descriptions.
152 * Additional (optional) param $onlyactive has been added to get_enrolled_users, count_enrolled_users
153 functions to get information for only active (excluding suspended enrolments) users. Included two
154 helper functions extract_suspended_users, get_suspended_userids to extract suspended user information.
155 * The plugin_manager class now provides two new helper methods for getting information
156 about known plugins: get_plugins_of_type() and get_subplugins_of_plugin().
157 * The get_uninstall_url() method of all subclasses of plugininfo_base class is now expected
158 to always return moodle_url. Subclasses can use the new method is_uninstall_allowed()
159 to control the availability of the 'Uninstall' link at the Plugins overview page (previously
160 they would do it by get_uninstall_url() returning null). By default, URL to a new general plugin
161 uninstall tool is returned. Unless the plugin type needs extra steps that can't be handled by
162 plugininfo_xxx::uninstall() method or xmldb_xxx_uninstall() function, this default URL should
163 satisfy all plugin types.
165 Database (DML) layer:
166 * $DB->sql_empty() is deprecated, you have to use sql parameters with empty values instead,
167 please note hardcoding of empty strings in SQL queries breaks execution in Oracle database.
168 * Indexes must not be defined on the same columns as keys, this is now reported as fatal problem.
169 Please note that internally we create indexes instead of foreign keys.
172 * M.util.help_icon has been deprecated. Code should be updated to use moodle-core-popuphelp
173 instead. To do so, remove any existing JS calls to M.util.help_icon from your PHP and ensure
174 that your help link is placed in a span which has the class 'helplink'.
178 * Pagelib: Numerous deprecated functions were removed as classes page_base, page_course
179 and page_generic_activity.
180 * use $CFG->googlemapkey3 instead of removed $CFG->googlemapkey and migrate to Google Maps API V3
181 * Function settings_navigation::add_course_editing_links() is completely removed
182 * function global_navigation::format_display_course_content() is removed completely (the
183 functionality is moved to course format class)
184 * in the function global_navigation::load_generic_course_sections() the argument $courseformat is
186 * New component and itemid columns in groups_members table - this allows plugin to create protected
187 group memberships using 'xx_yy_allow_group_member_remove' callback and there is also a new restore
188 callback 'xx_yy_restore_group_member()'.
189 * New general role assignment restore plugin callback 'xx_yy_restore_role_assignment()'.
190 * functions get_generic_section_name(), get_all_sections(), add_mod_to_section(), get_all_mods()
191 are deprecated. See their phpdocs in lib/deprecatedlib.php on how to replace them
194 * moodle-enrol-notification has been renamed to moodle-core-notification
195 * YUI2 code must now use 2in3, see http://yuilibrary.com/yui/docs/yui/yui-yui2.html
196 * M.util.init_select_autosubmit() and M.util.init_url_select() have been deprecated. Code using this should be updated
197 to use moodle-core-formautosubmit
199 Unit testing changes:
200 * output debugging() is not sent to standard output any more,
201 use $this->assertDebuggingCalled(), $this->assertDebuggingNotCalled(),
202 $this->getDebuggingMessages() or $this->assertResetDebugging() instead.
206 Database layer changes:
207 * objects are not allowed in paramters of DML functions, use explicit casting to strings if necessary
210 * DDL and DML methods which were deprecated in 2.0 have now been removed, they will no longer produce
211 debug messages and will produce fatal errors
215 * send_stored_file() has changed its interface
216 * deleted several resourcelib_embed_* functions from resourcelib.php
220 removed unused libraries:
221 * odbc, base32, CodeSniffer, overlib, apd profiling, kses, Smarty, PEAR Console, swfobject, cssshover.htc, md5.js
224 * new admin/tool plugin type
225 * new context API - old API is still available
226 * deleted users do not have context any more
227 * removed global search
233 * basic suport for restore from 1.9
234 * new mobile devices API
241 * new DML API - http://docs.moodle.org/dev/DML_functions
242 * new DDL API - http://docs.moodle.org/dev/DDL_functions
243 * new file API - http://docs.moodle.org/dev/File_API
244 * new $PAGE and $OUTPUT API
246 * new theme API - http://docs.moodle.org/dev/Theme_changes_in_2.0
247 * new javascript API - http://docs.moodle.org/dev/JavaScript_usage_guide
