* Added BenchmarkHelper that can measure the execution time of a block in a template and reports the result to the log. Example:
<% benchmark "Notes section" do %>
<%= expensive_notes_operation %>
<% end %>
Will add something like "Notes section (0.345234)" to the log.
* Added ActionController::Caching::Sweeper as an improved an easier to use sweeper. The new sweepers work on a single-step approach instead of two-steps like the old ones. Before
def after_save(record)
@list = record.is_a?(List) ? record : record.list
end
def filter(controller)
controller.expire_page(:controller => "lists", :action => %w( show public feed ), :id => @list.id)
controller.expire_action(:controller => "lists", :action => "all")
@list.shares.each { |share| controller.expire_page(:controller => "lists", :action => "show", :id => share.url_key) }
end
..after:
def after_save(record)
list = record.is_a?(List) ? record : record.list
expire_page(:controller => "lists", :action => %w( show public feed ), :id => list.id)
expire_action(:controller => "lists", :action => "all")
list.shares.each { |share| expire_page(:controller => "lists", :action => "show", :id => share.url_key) }
end
The new sweepers can also observe on the actions themselves by implementing methods according to (before|after)_$controller_$action. Example of a callback that'll be called after PagesController#update_title has been performed:
def after_pages_update_title
expire_fragment(%r{pages/#{controller.assigns["page"].id}/.*})
end
Note that missing_method is delegated to the controller instance, which is assigned in a before filter. This means that you can call expire_fragment instead of @controller.expire_fragment.
* Added that Fragments#expire_fragment now accepts as a regular expression as the name thereby deprecating expire_matched_fragments
* Fixed that fragments shouldn't use the current host and the path as part of the key like pages does
* Added conditions to around_filters just like before_filter and after_filter
*1.8.1* (20th April, 2005)
* Added xml_http_request/xhr method for simulating XMLHttpRequest in functional tests #1151 [Sam Stephenson]. Example:
