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.
Avoid ajax reloads when URLs differ in irrelevant ways,
e.g. admin/?locale=de vs. admin?locale=de.
This caused problems with the translatable module
reloading page content where it didn't need to,
because some previous robustness patches to the same problem
didn't apply (they only removed trailing slashes, ignoring
query parameter strings). The visible problem for this was
a broken tree panel, because it was ajax-loaded in parallel
with its container. Depending on ajax response order,
this would break the inner panel (in this case the tree),
since its original container was replaced with a new DOM.
In certain cases (e.g. with the mi_NZ locale),
the i18n system would regard a langage as already
loaded if it was restored from a cached, but empty
translation list (through Zend_Translate).
This was due to the cache key being generated
based solely on the content, rather than taking
other options like the locale into account.
This is reverting templates back to pre-3.0 conventions,
which were dominated by XHTML templates.
HTML5 allows both self-closing and unclosed tags,
so opting for self-closing to achieve maximum compatibility.
The classnames on the add-new button and breadcrumbs were not
translated due to the use of singular_name() instead of
i18n-singular_name() in GridFieldAddNewButton and GridFieldDetailForm.
In CMSBreadcrumbs.ss the (TopLevel)Controller is not recognized within
the Breadcrumbs loop, so the class that is used in css to style the
icon cannot be created. Moving the construction outside the loop will
remedy this. As far as I can see this works within the CMS.
