The completion cache is currently not marked as simpledata. On the
course page it is frequently retrieved hundreds of times which results
in many calls to the slow unserialize function. By making a slight
change to the data format (using arrays instead of objects) we can
mark it as simpledata, which will avoid using unserialize.
The s() function includes a comment saying that parameter options
should be modified to improve performance once PHP 5.4 is required.
Since Moodle has required PHP 5.4 for some time, we should probably
make the change and remove the comment.
According to my benchmarking, these changes make s() about 7% faster
and will save a staggering 2ms from a typical course view that calls
it 8,000 times.
Delete tablesupdatedbyscenario before db reset to ensure
db is fully reset. In case user exits or process terminated
then the file will be left and can lead to wrong results
Use core functions that are faster for test file creation.
To support large requests for hashes, the core hash function
must support large hashes without recursion. PHP has a default
recursion depth of 100 and long hashes don't support this.
Remove transactions as they create performance problems for larger
courses and doesn't introduce significant benefit for developers.
Performance changes meant the times were much faster, a reasonable
guess was taken on performance of an average machine.
1. getMock()
2. setExpectedException()
3. checkForUnintentionallyCoveredCode renamed to beStrictAboutCoversAnnotation
4. beStrictAboutTestSize renamed to enforceTimeLimit
5. UnitTestCase class is now fully removed.
Final deprecation of the following methods:
- course_modinfo::build_section_cache()
- cm_info::get_deprecated_group_members_only()
- cm_info::is_user_access_restricted_by_group()
Plus throw coding exception for direct calls of the following:
- cm_info::get_url()
- cm_info::get_content()
- cm_info::get_extra_classes()
- cm_info::get_on_click()
- cm_info::get_custom_data()
- cm_info::get_after_link()
- cm_info::get_after_edit_icons()
- cm_info::obtain_dynamic_data()
