MDL-36363 cache: clean up pre-integration
2013-01-24 15:09:20 +13:00
This files describes API changes in /cache/stores/* - cache store plugins.
Information provided here is intended especially for developers.
MDL-47832 cache: removed data source aggregate functionality Cache data source aggregate functionality was found to be broken and unused, because of this the decision was made to remove it rather than fix it. As it was broken we did not follow typical deprecation methods and instead the code was removed outright with only structure remaining and left deprecated.

=== 2.9 ===
* Cache data source aggregation functionality has been removed. This functionality was found to be broken and unused.
It was decided that rather than fixing it it should be removed.
As well as the processing code being removed the following API changes have been made.
The following changes have come about because of it:
- cache_definition::$datasourceaggregate is deprecated an unused.
- cache_definition::load Argument 3 (final arg) is now unused.
- cache_factory::create_cache_from_definition Argument 4 (final arg) is now unused.
- cache::make Argument 4 (final arg) is now unused.
MDL-45699 cache: acceptance test improvements We now use the unit test cache config class when running acceptance tests so that the same defines are applicable there.
2014-12-09 09:20:21 +13:00
* cache_config_phpunittest has been renamed to cache_config_testing
MDL-48568 cache: stores now determine testing Cache stores are now responsible for deciding if they are suitable for use as the primary cache store during unit and acceptance tests Changes are as follows: * New method: cache_store::ready_to_be_used_for_testing * Core cache store have been updated to override this method as required. * MongoDB usesafe default changed to true to match actual default behaviour.
2014-12-12 09:27:16 +13:00
* New method cache_store::ready_to_be_used_for_testing() that returns true|false if the store is suitable and ready for use as the primary store during unit and acceptance tests.
MDL-39459 cache: mode included in stats output The cache store mode is now included in the performance stats printed at the bottom of the page. It is represented as either [a] [s] or [r] and a title is used to actually state the mode.
2014-11-21 11:02:32 +13:00
* cache_helper::get_stats structure we changed to include the cache mode.
MDL-47832 cache: removed data source aggregate functionality Cache data source aggregate functionality was found to be broken and unused, because of this the decision was made to remove it rather than fix it.

MDL-43349 cache: is_ready now checks are_requirements_met by default (Fixes the fixed forwarded static call bug reverted in a5581c7)

=== 2.7 ===
* cache_store::is_ready is no longer abstract, calling cache_store::are_requirements_met by default.

=== 2.6 ===
* All cache instances are recorded and subsequent requests are given a reference to the original instance.
* The persistent option for the cache definition has been deprecated. Please use the staticacceleration option instead.
* There is a new static acceleration option. If enabled data passing through the cache is held onto.
* The persistentmaxsize option has been renamed to staticaccelerationsize. It does the same thing.
* cache_definition::should_be_persistent has been deprecated. Please call cache_definition::use_static_acceleration instead.
* cache_definition::get_persistent_max_size has been deprecated. Please call cache_definition::get_static_acceleration_size instead.
MDL-40903 cache: renamed loader method to reflect static accelerator
2013-09-17 13:39:49 +12:00
* cache::is_using_persist_cache() has been deprecated. Please call cache::use_static_acceleration()
* cache::is_in_persist_cache() has been deprecated. Please call cache::static_acceleration_has()
* cache::get_from_persist_cache() has been deprecated. Please call cache::static_acceleration_get()
* cache::set_in_persist_cache() has been deprecated. Please call cache::static_acceleration_set()
* cache::delete_from_persist_cache() has been deprecated. Please call cache::static_acceleration_delete()
* If you have any custom cache loaders you will need to rename these methods if you have overriden them and adjust any calls you may have made to them.
