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

For that issue, we needed to have the DataQuery as the second parameter to
DataQuery's augmentSQL call. Fortunately, DataQuery was already passing this
argument. However, where the function was defined in DataExtension, the
argument was not present. Thus, subclasses of DataExtension could not add the
parameter to their function signature if they were running in PHP strict mode
because PHP will complain that the signatures don't match.
Rendering potentially 1000s of nodes can exceed the CPU and memory constraints
of a normal PHP process, as well as the rendering capabilities of browsers.
Set a hard maximum for the renderable nodes, deferring to a "show as list" action
in the main CMS tree. For TreeDropdownField, we don't have the list fallback option,
so ask the user to search for the node title instead.
Also makes both the "node_threshold_total" and "node_threshold_leaf" values configurable
- Renamed $minNodeCount to more accurate $nodeCountThreshold
- The $minNodeCount attribute wasn't properly respected
during actual querying, so SilverStripe would always traverse
the entire tree (and load all objects into memory),
before then marking nodes as "unexpanded", which prevents
them from actually being rendered.
- Fixes nodes on search results to be expanded by default
- Fixes nodes on search results to correctly ajax-expand
In 3.0 there was some confusion about whether DataLists and ArrayLists
were mutable or not. If DataLists were immutable, they'd return the result, and your code
would look like
$list = $list->filter(....);
If DataLists were mutable, they'd operate on themselves, returning nothing, and your code
would look like
$list->filter(....);
This makes all DataLists and ArrayList immutable for all _searching_ operations.
Operations on DataList that modify the underlying SQL data store remain mutating.
- These functions no longer mutate the existing object, and if you do not capture the value
returned by them will have no effect:
ArrayList#reverse
ArrayList#sort
ArrayList#filter
ArrayList#exclude
DataList#dataQuery (use DataList#alterDataQuery to modify dataQuery in a safe manner)
DataList#where
DataList#limit
DataList#sort
DataList#addFilter
DataList#applyFilterContext
DataList#innerJoin
DataList#leftJoin
DataList#find
DataList#byIDs
DataList#reverse
- DataList#setDataQueryParam has been added as syntactic sugar around the most common
cause of accessing the dataQuery directly - setting query parameters
- RelationList#setForeignID has been removed. Always use RelationList#forForeignID
when querying, and overload RelationList#foreignIDList when subclassing.
- Relatedly,the protected variable RelationList->foreignID has been removed, as the ID is
now stored on a query parameter. Use RelationList#getForeignID to read it.
The entire framework repo (with the exception of system-generated files) has been amended to respect the 120c line-length limit. This is in preparation for the enforcement of this rule with PHP_CodeSniffer.
Config system used to provide an add_static_source method, which was intended for
use by Extensions to add statics. But extensions for a class arent initialised
until at least one instance of that class is created, so before that the
Config system didnt include values from extensions
This patch reverses the control flow, so that the Config system explictly asks
each Object for its additional config sources via the new method
get_extra_config_sources. This method returns an array that can contain
string names of classes and also raw associative arrays.
The developer visible change is that Extension#add_to_class has been
deprecated. Instead there is a new method, get_extra_config, which has
the same method signature but needs to guarantee that it doesnt
cause side effects. Additionally there is no need to call
parent::get_extra_config - this is handled automatically.
Hierarchy#liveChildren was generating a list of all IDs of all pages
on staging. When a site had lots of pages, this basically killed the
tree.
Fix by adding new versioned mode, stage_unique, which uses a
subselect to only return items from a stage that are in no
other stage.
static function on Extension classes.
BUGFIX FulltextSearchable didn't pass through arguments, use now
available $args parameter with FulltextSearchable::add_to_class()
This solves a bugfix when calling singleton($className)->summaryFields() and Versioned kicks back. It is needed to by the GridField functionality to get default columns to show.
This is due to DataExtension calls ClassName::extraStatics() when calling ::load_extra_statics() statically, we need to pass in class and extension.
API CHANGE: augmentSQL is now passed a DataQuery object from which query parameters can be extracted.
API CHANGE: DataObjectDecorators that manipulate the query can now define augmentDataQueryCreation().
API CHANGE: The container class argument for DataObject::get() is deprecated.
API CHANGE: DataObject::buildSQL() and DataObject::extendedSQL() are deprecated; just use DataObject::get() now.
API CHANGE: DataObject::instance_get() and DataObject::instance_get_one() are deprecated, and can no longer be overloaded.
API CHANGE: DataObject::buildDataObjectSet() is deprecated.
API CHANGE: Cant't call manual manipulation methods on DataList such as insertFirst()
