This commit introduces support to the LTI module for LTI 2.0.
As well as the initial commit the following changes were made
and then squashed into the single commit for integration:
* Fixed bug in services
Fixed bug which limited characters allowed in values of template
variables (e.g. vendor ID) in service endpoints.
Changed language file to refer to tool registrations rather than
tool proxies.
* Refactored service classes
Moved classes relating to services into areas where Moodle will
autoload them
* Ran code through code checker
Removed all errors reported by the Code checker module
excluding third-party OAuth.php file.
* UI improvements
Mainly when adding an external tool to a course - fields which
should not be changed for a selected tool are either hidden or
disabled. Admin settings page now shows the Tool Registration
name against a tool rather than the launch URL, and the
registration URL replaces the GUID on the tool registrations
page.
* Updated tool proxy registration
Added check of tool proxy to ensure only offered capabilities
and services are included. Also check tool proxy when processing
a service request.
* Code review changes
Some fixes based on code review by Mark Nielsen and addition of
some PHPDocs comments.
* Updates from code/PHPdocs checks
Removed use of eval and corrected invalid PHPdocs for new
functions/classes
* Corrected namespace error and incorrect string terminator
* Updates based on forum feedback
Added dependencies and backup, restore and uninstall methods for
ltiservice subplugins.
Changed most uses of is_null to empty
* Updated custom parameters test
Updated test_split_custom_parameters to include new function
parameters.
Corrected PHPdoc entry for lti_split_custom_parameters
Fixed incorrect line separators in ltiservice.php
* Added require_capability to registrationreturn.php
* SQL and EOL updates
Moved PHP variable in SQL into a named parameter
Improved checks for end-of-line characters to include CR and LF
on their own or together
* Check for semicolon separators
Semicolon separators in custom parameters are changed to EOL
characters when upgrading to the 2014100100 version.
* Remove unused file
basiclti.js file not being used so removed.
* Adjust line lengths
Split long lines in upgrade.php
* Added savepoint to upgrade.php
savepoint omitted from earlier update to upgrade.php
* Updated namespaces and upgrade
Service and resource classes moved into .../local/...
Upgrade SQL moved into a function and unit test created
* Updated lti_tool_proxies table
Added indices and foreign keys to lti_tool_proxies table
* Fixed formatting and documentation issues
* ltiservice class moved into local
* Replaced lti_scale_used comments
Put back commented out code for lti_scale_used
* Removed redundant sesskey code
* Fixed namespace and path check
Updated ltiservice namespace for move into local
Added check for existence of $_SERVER['PATH_INFO']
* Updated upgrade code
Added indices and keys to lti_tool_settings table when upgrading
Fixed errors in upgradelib_test.php (thanks to jleyva)
Update SQL to use Moodle functions
* Use of empty with class method
PHP 5.4 does not like the use of empty with a class method so saved the
value to a variable first. PHP 5.5 seems to accept the use of a method
with empty.
* Removed redundant indices
Removed creation of indices for foreign keys on lti_tool_settings table
from install.xml and upgrade.php
* Fixes based on feedback
Minor changes and corrections based on review in JIRA
* Fixed bug in toolproxy service
Corrected bug which failed to respond properly to an invalid request
Also updated upgrade.txt file
* Improved admin navigation
Added the manage tool registrations page as a separate entry on the
admin menu (within a folder named LTI). Made this entry the current
position for the related pages.
* Updated PHPdocs with class names
Added class names with namespaces to PHPdocs to replace generic
references to "object"
* Changed object to iframe
Use of object tag in register.php changed to use an iframe tag in line
with the similar update made to view.php.
* Improved registration process
A message is now displayed if the registration page has not been loaded
in the iframe within 20 seconds. If a user is returned to Moodle
without a tool proxy being sent, the registration is moved back from
pending to configured.
* Fixes for integration
Removed comment - the template is the default path unless overridden, so
get_path and get_template should both be defined.
Added comment and intval to fix the issue with obtaining an error
reason.
When working against external services it can be advantageous to not
have automated tasks all hit the service at the exact same time from
many different installations.
This change allows the use of 'R' in hour/minute fields of the scheduled
task definition so a task will be installed with a 'random' hour/minute
value for these sort of occasions.
Note that the task will be installed in the database with a defined
time, this simply randomises the time chosen when loading from the
definiton.
Learnwise was an old LMS that no longer exists. (Last reference found on
Google from 2009.) So we are removing the ability to import questions in
that format.
Credit goes to PJ King. I was trying to add unit tests for this new
behaviour but it turned out there are many hard-coded dependencies and
it's not easy to make the whole machinery support alternative location
of testable (fake) plugins.
