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
The docs incorrectly stated that DataList::filter() needed escaped input, but this isn't true as the ExactMatch filter (and others) escape the values for you.
Anyone following that advice would have double escaped arguments
Allow DataList::limit() to take a null value to remove the limit.
Added tests for limit(). Note the one failure, currently the ORM doesn't support unlimited values with an offset.
Cleanup of framework's use of @package and @subpackage labels and additional of labels for classes missing packages.
Moved all GridField related components to the one name.
Countless spelling fixes, grammar for other comments.
Link ClassName references in file headers.
Lazy loading no longer loads fields from the versions table when querying. This could lead to incorrect data being displayed if the data on the object and the version it pointed to did not match.
API methods to allow setting of the context of the query that generated the DataObject on that object (used by the lazy loading mechanism to correctly query the Stage, Live, or Versions tables)
See https://github.com/silverstripe/sapphire/pull/1178 for context.
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.
The table name in the join was being escaped, though table
names aren't escaped anywhere else. This breaks
namespaced classes, which rely on unescaped backslashes.
DataList had several methods that should act on a copy and return
that copy, but was instead mutating the existing list.
We cant change this behaviour in the 3.0 line for backwards compt.
reasons, but this makes the desired behavior the default, and
makes disabling the mutation in 3.1 easier
It also introduces two new methods to deal with the common pattern
of wanting to modify the underlying dataQuery, which we want to be
able to reliably do in a way that always acts immutably. The main
method of these two is alterDataQuery
