1) Deal in fully qualified URL resources through the rest
interface. All rest methods are now passed the complete url in
request->url.
2) Create rest::resolve() which lets individual resource definition
code convert a full url into the appropriate matching resource.
Implement gallery_rest::resolve() and tag_rest::resolve()
3) Reimplement tag_rest's get() and post() methods. They're much
simpler now.
4) Implement the tags_rest helper which supports working with the
entire tags collection.
1) Simplify gallery_rest to return flat models, no children and do no
validation for now.
2) Flatten the REST replies and use HTTP codes to indicate
success/failure instead of additional status messages.
3) Use the message and error code support in the base Exception class,
instead of brewing our own in Rest_Exception.
4) Get rid of rest::success() and rest::fail() -- we only need
rest::reply() since all failures are covered by throwing an
exception.
5) Get rid of /rest/access_key and just use /rest for authentication.
6) Inline and simplify rest::normalize_request since we only use it once
7) Change rest::set_active_user to succeed or throw an exception
8) Extract Rest_Exception::sendHeaders into rest::send_headers()
Here's what's currently broken:
1) Data validation. There currently is none
2) Logging. That's gone too
3) image block and tag code is broken
4) Tests are broken
5) No movie support
The request key is put in the X-Gallery-Request-Key header
The HTTP method can be override by using the X-Gallery-Request-Method header
Normalize the request data so that it doesn't matter where it comes from (HTTP get or HTTP post request)
