This pattern improves over the current usage of singleton by allowing type inference.
This also better supports refactor, code usage detection, and auto-completion of classes.
Database abstraction broken up into controller, connector, query builder, and schema manager, each independently configurable via YAML / Injector
Creation of new DBQueryGenerator for database specific generation of SQL
Support for parameterised queries, move of code base to use these over escaped conditions
Refactor of SQLQuery into separate query classes for each of INSERT UPDATE DELETE and SELECT
Support for PDO
Installation process upgraded to use new ORM
SS_DatabaseException created to handle database errors, maintaining details of raw sql and parameter details for user code designed interested in that data.
Renamed DB static methods to conform correctly to naming conventions (e.g. DB::getConn -> DB::get_conn)
3.2 upgrade docs
Performance Optimisation and simplification of code to use more concise API
API Ability for database adapters to register extensions to ConfigureFromEnv.php
Specific case: LeftAndMain::$session_keepalive_ping = true cannot be
set to false in config.yml for some cases because the value is ignored
when merge_array_low_into_high() is processing the config arrays.
BUG Resolve issue with DirectorTest breaking RequestProcessor
Injector::nest and Injector::unnest are introduced to better support sandboxing of testings.
Injector and Config ::nest and ::unnest support chaining
Test cases for both Injector::nest and Config::nest
Bots often have the habit of trying a next page, even if there isn't one.
Thus, using CurrentPage < TotalPages, prevents from unwanted next-links being shown.
Fixes issue of templates not being found when a Page's main/Layout templates are split between the project and theme folders. Adds more expansive testing for template loading.
The error thrown by `parseStatic` when there's an unexpected token is now more meaningful as it states the type of token that was encountered as well as the class that it was found in.
Previously, generated cache results that returned 0, '', array() etc
were being ignored. This change narrows it down to just false.
Ideally we would use a EmptyCacheHit object to be very specific for
these cases, but perhaps this approach is a bit overkill.
