This bug will surface when using the ORM and adding an join to DataList
where a DataObject inherits another DataObject.
If you for example want to restrict the number of pages that only have a
related Staff object:
$list = DataList::create('Page')
->InnerJoin('Staff', '"Staff"."ID" = "Page"."StaffID");
This will create a SQL query where the INNER JOIN is before the
LEFT JOIN of Page and SiteTree in the resulting SQL string. In MySQL
and PostgreSQL this will create an invalid query.
This patch solves the problem by sorting the joins.
Avoid PHPUnit throwing "test didn't run any assertions"
notices in PHP. If nothing else, it keeps test output
looking less broken by default, making it more likely
that actual errors do get noticed.
The original intention of this method was to be a rewrite
check by the installer, but it doesn't belong in
DatabaseAdmin, nor is it used by the installer anymore,
since the rewrite test is done by the installer directly.
Quoted table / column names to make test cases work in postgres
BUG Fixed issue with SQLQuery::lastRow crashing on empty set. Added test cases for lastRow and firstRow.

In a usual CMS request, DataObject::db() is called potentially
thousands of times, calling Config::get() constantly for the same
uninherited statics, which is slow. This improves performance
by caching those into DataObject::$_cache_db
On sites with lots of modules, and pages with plenty of database
queries, DataObject::custom_database_fields() can be called
thousands of times, and slow down page render times. This fixes
it so the fields are cached by class in a static variable, and
are cleared when reset() is called on the DataObject.
SS_HTMLValue::getContent() uses urldecode() on the content returned
by saveHTML() -- this was done to fix encoded HTML entities like
square brackets, which are used by shortcodes. Unfortunately, this
also removes valid characters like "+" from the content.
This fixes it so square bracket entities are decoded *only*, and
leaves everything else as-is.
The specific situation where this is useful is where populateDefaults on
DataObjects needs to query the database. This will break the dev/build
when it tries to create the object via singleton - the query will not be
able to be executed if the table is not there or its schema has changed.
For an example of such use case see Translatable::populateDefaults.
