This is a bug that combines Hierarchy, Versioned and LeftAndMain admins and CMSSiteTreeFilters.
This bug can be reproduced by having a large site tree with enough deleted pages in it so it doesn't
pre load all the children pages when initially opening an admin. Filter by either 'All pages including deleted'
or 'Deleted pages'. For CMS users it will look like deleted pages are gone.
The solution involves a couple of smaller fixes in both CMS and framework modules.
1) Ensure that 'numHistoricalChildren' are used instead of 'numChildren' when dealing with deleted pages
2) LeftAndMain::currentPage() deletes all the 'marking' cache previously built up by Hierarchy::markPartialTree()
3) Use Versioned::get_included_deleted() instead of raw DB queries against the DataObject tables when calculating parents in CMSSiteTreeFilter
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
While the check for `$classname` was done in the first conditional, it was left out of the other two, leading to potential issues when an invalid ID was given, instead of the expected `false`.
Broke because the <form> tag was returned, while
the client logic was expecting the whole <div> including the <form>.
Fixed to display the button bar at the bottom,
and tested with validation errors as well as switching from/to
the panel via ajax.
The specific example for this issue is InlineFormField - results in actionName() on non-object error. See #2527 for context.
Include parentheses for coding conventions
Updates the CMS profile page and SecurityAdmin to give developers a few ways to customise the required fields.
Added extension hook updateValidator for getValidator for things like modules to inject required fields to go along with Injector for replacing the entire class for project specific use.
A new form instance was being constructed for the response, which mean
that a lot of the validation information was lost. This fix means that:
* Enterered data is correctly persisted.
* A validation error notification is displayed.
Currently help menu item is the only external link in the CMS and the ability for it to work is hardcoded in the template. This request makes the target attribute definable by CMSMenu::add_link().
Adds documentation for how to add a basic external link to the CMS.
