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
Previously selectFromTable would simply try to select the composite field name. This expands the extraField name to include the children field names and uses CompositeDBField::writeToManipulation to generate the correct SQL for the queries.
Move functionality from static start and destroy functions into instance
methods, allowing these to be overloaded. This works the same way as
calling Session::set() which then in turn calls inst_set()
Additionally use Injector to create the default Session instance to
allow the class to be swapped out.
BUG Disabled disruptive test case in DirectorTest
API RequestProcessor and VersionedRequestFilter now both correctly implement RequestFilter
Better PHPDoc on RequestFilter and implementations
This issue is caused by the odd default behaviour of Zend_Date, which attempts to parse yyyy-mm-dd format date and times as though they were yyyy-dd-mm.
DataObject::validate() is currently set to protected, but this means
you can't call validate() from outside the context of itself unless
you overload the method to use a public visibility and then call
parent::validate()
As it would turn out, most classes that overload this method already
set the visibility to public, so it would make sense the parent matches
that as well.
- Document the format for descriptor arrays
- Implement the behaviour that developers have come to expect for
string descriptors of indexes
- Add test for handling of unique indexes (MySQL & sqlite3)
- Resolve#2403
Versioned needs to convert unique indexes to non-unique for its suffixed
tables, such as Foo_Live and Foo_versions. Because DataObject accepts
string descriptors such as array('UniqIDX' => 'unique (Uniq)') as well
as array-based descriptors, Versioned needs to recognize string
descriptors. This patch accomplishes that. Before, Versioned would fail
to convert string-described indexes to non-unique, resulting in run-time
errors when creating a new version of an object.
If more than two $from were added through SQLQuery->addFrom(),
the getOrderedJoins() comparison kicks in. It assumes all $from
parts are in array notation, which isn't always the case.
For legacy reasons, and because we don't have full API support,
you can still add literal joins through addFrom('INNER JOIN ...').
On PHP 5.3, the ordering comparison still works because it
allows array access in strings, with string rather than numeric indexes.
Thankfully that's no longer supported in PHP 5.4.
DataQuery::initialiseQuery() will add a default sort to a query,
and when calling up an aggregate it will make a query like this
which doesn't make sense:
SELECT MAX("LastEdited") FROM "Member" ORDER BY "ID"
In this case there is no need to add the ORDER BY, and it will
break databases like MSSQL in cases such as
GenericTemplateGlobalProvider
which provides a default List() function for adding aggregates
into SSViewer template cacheblocks.
If we add a limit, however, then it does make sense:
SELECT MAX("LastEdited") FROM "Member" ORDER BY "ID" LIMIT 10
This fixes SQLQuery::aggregate() to NOT add an ORDER BY to an
aggregate call if there is no limit.
If multiple image manipulations are performend the resulting cached image is stored in assets/_resampled because the cached version of the image has no ParentID, which cacheFilename needs to set the correct path.
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.
The function "first" on ArrayList uses the PHP function "reset", which
returns false if there aren't any elements in the array. Two functions
inside ArrayList use this function, "canFilterBy" and "byID". I've
changed these functions to catch the possibility of a false return from
first().
Commit 964b3f2 fixed an issue where dbObject was returning casting helpers for
fields that were not actually DB objects, but had something in $casting config.
However, because dbObject was no longer calling DataObject->castingHelper, this
exposed a bug that the underlying function db($fieldName) was not returning
field specs for the base fields that are created by SS automatically on all
DataObjects (i.e. Created, LastEdited, etc).
This commit fixes the underlying issue that DataObject->db($fieldName) should
return the field specs for *all* DB fields like its documentation says it will,
including those base fields that are automatically created and do not appear in
$db.
SQLQuery->setLimit(0, 99) should result in "SELECT ... LIMIT 0 OFFSET 1".
In fact it does "SELECT ..." without a LIMIT clause at all,
which is unexpected. This is regardless of the $offset value.
This caused problems when duplicate() was used in the CMS UI
to duplicate a SiteTree object. Since every object of this type
has a ParentID relation, it copied this empty relation into
new "ghost page".
