* request.formats is much simpler now
* For XHRs or Accept headers with a single item, we use the Accept header
* For other requests, we use params[:format] or fallback to HTML
* This is primarily to work around the fact that browsers provide completely
broken Accept headers, so we have to whitelist the few cases we can
specifically isolate and treat other requests as coming from the browser
* For APIs, we can support single-item Accept headers, which disambiguates
from the browsers
* Requests to an action that only has an XML template from the browser will
no longer find the template. This worked previously because most browsers
provide a catch-all */*, but this was mostly accidental behavior. If you
want to serve XML, either use the :xml format in links, or explicitly
specify the XML template: render "template.xml".
* Move #set_cookie and #delete_cookie inline to optimize. These optimizations should
almost certainly be sent back upstream to Rack. The optimization involves using
an ivar for cookies instead of indexing into the headers each time.
* Was able to use a bare Hash for headers now that cookies have their own joining
semantics (some code assumed that the raw cookies were an Array).
* Cache blankness of body on body=
* Improve expand_cache_key for Arrays of a single element (common in our case)
* Use a simple layout condition check unless conditions are used
* Cache visible actions
* Lazily load the UrlRewriter
* Make etag an ivar that is set on prepare!
* Tentatively replaced HeaderHash with SimpleHeaderHash, which does not preserve
case but does handle converting Arrays to Strings in to_hash. This requires
further discussion.
* Moved default_charset to ActionDispatch::Response to avoid having to hop over
to ActionController. Ideally, this would be a constant on AD::Response, but
some tests expect to be able to change it dynamically and I didn't want to change
them yet.
* Completely override #initialize from Rack::Response. Previously, it was creating
a HeaderHash, and then we were creating an entirely new one. There is no way to
call super without incurring the overhead of creating a HeaderHash.
* Override #write from Rack::Response. Its implementation tracks Content-Length,
and doing so adds additional overhead that could be mooted if other middleware
changes the body. It is more efficiently done at the top-level server.
* Change sending_file to an instance_variable instead of header inspection. In
general, if a state is important, it should be set as a property of the response
not reconstructed later.
* Set the Etag to @body instead of .body. AS::Cache.expand_cache_key handles
Arrays fine, and it's more efficient to let it handle the body parts, since
it is not forced to create a joined String.
* If we detect the default cache control case, just set it, rather than setting
the constituent parts and then running the normal (expensive) code to generate
the string.
* Rails actions are now Rack endpoints, and can be retrieved
via FooController.action(name) and called with an env
* Updated some tests that relied on the old internal
#process/#call implementation
Resolved all the conflicts since 2.3.0 -> HEAD. Following is a list
of commits that could not be applied cleanly or are obviated with the
abstract_controller refactor. They all need to be revisited to ensure
that fixes made in 2.3 do not reappear in 3.0:
2259ecf368
AR not available
* This will be reimplemented with ActionORM or equivalent
06182ea02e
implicitly rendering a js response should not use the default layout
[#1844 state:resolved]
* This will be handled generically
893e9eb995
Improve view rendering performance in development mode and reinstate
template recompiling in production [#1909 state:resolved]
* We will need to reimplement rails-dev-boost on top of the refactor;
the changes here are very implementation specific and cannot be
cleanly applied. The following commits are implicated:
199e750d463942cb406ef8ea9f85d4e3b166aab3ae9f258e0344423126c60cb020b4d6
workaround for picking layouts based on wrong view_paths
[#1974 state:resolved]
* The specifics of this commit no longer apply. Since it is a two-line
commit, we will reimplement this change.
8c5cc66a83
make action_controller/layouts pick templates from the current instance's
view_paths instead of the class view_paths [#1974 state:resolved]
* This does not apply at all. It should be trivial to apply the feature
to the reimplemented ActionController::Base.
87e8b16246
fix HTML fallback for explicit templates [#2052 state:resolved]
* There were a number of patches related to this that simply compounded
each other. Basically none of them apply cleanly, and the underlying
issue needs to be revisited. After discussing the underlying problem
with Koz, we will defer these fixes for further discussion.
