This locking system is designed to be used everywhere requiring
locking in Moodle. Each use of the locking system can be configured
to use a different type of locking (or the same type with a different
configuration).
The first supported lock types are memcache, memcached, file (flock),
db (specific handlers for pg, mysql and mariadb).
* Upgrade function to remove duplicates from the grade item duplicates
column. Duplicates were causing sorting to fail in some cases.
* Add some unit tests which simulate sort order duplicate data and
verify that they have been removed.
Instead we will create new MUC caches inside each filter plugin.
Please note that all cache filters should work with local caches
without the need of strict cache invalidation.
Too many functions, too different parameters, unnecessary DB queries.
All repositories developed for Moodle 2.3-2.5 will continue to work.
Also get rid of DB field files_reference.lifetime, it is not used by
anybody except repository itself.
This parallels question_attempt->minfraction, which allows the
fractional mark to go below zere.
This is needed to allow the certainty-base marking behaviours to work
better.
quiz_question_statistics_stats renamed to question_statistics_calculator
separate class question_statistics used to store calculated stats
and api changed, also code generally cleaned up.
Fields files.referencelastsync and files.referencelifetime just waste the space and actually duplicate the fields
files_reference.lifetime and files_reference.lastsync
This patch includes:
* version column removed from modules table, now using standard config, this allows decimal version for modules
* version column removed from block table, now using standard config, this allows decimal version for blocks
* module version.php can safely use $plugins instead of module
* new plugin_manager bulk caching, this should help with MUC performance when logged in as admin
* all missing plugins are now in plugin overview (previously only blocks and modules)
* simplified code and improved coding style
* reworked plugin_manager unit tests - now using real plugins instead of mocks
* unit tests now fail if any plugin does not contain proper version.php file
* allow uninstall of deleted filters
to question bank
- move cron to clean up old cache records move code and
rename classes
- further review of the quiz reports statistics code
- starting to separate calculations of quiz stats, question stats and
response analysis
- introduce hashcode db field for cached stats convert
- code to use qubaids hashcode for caches
We just drop the old tables (including previous upgrade steps) and
re-create the new ones, because these tables just cache calculated
statistics. No important data is stored in them.
