- The types are:
-- Previous: The default and the previously used type
-- Subsequent: Compares against the next version
-- Current: Compares against the current version
- Allow switching between comparison types in index and diff views
-- Have links vary depending upon current comparison type
Previously only actions that were marked member_only or above were
subject to IP ban restrictions. This meant that certain actions that
weren't marked member_only, like creating new accounts, could still be
done by IP banned users.
Now IP banned users can't do any non-GET actions, which means they're
not allowed to even login to their accounts.
- The only string works much the same as before with its comma separation
-- Nested includes are indicated with square brackets "[ ]"
-- The nested include is the value immediately preceding the square brackets
-- The only string is the comma separated string inside those brackets
- Default includes are split between format types when necessary
-- This prevents unnecessary includes from being added on page load
- Available includes are those items which are allowed to be accessible to the user
-- Some aren't because they are sensitive, such as the creator of a flag
-- Some aren't because the number of associated items is too large
- The amount of times the same model can be included to prevent recursions
-- One exception is the root model may include the same model once
--- e.g. the user model can include the inviter which is also the user model
-- Another exception is if the include is a has_many association
--- e.g. artist urls can include the artist, and then artist urls again
* Allow both xml and json authentication in sessions controller.
* Raise an exception if a login attempt fails so that a) we return a
proper error for json/xml requests and b) failed login attempts get
reported to NewRelic (for monitoring abuse).
Previously the page-based (numbered) paginator would always count the
total_pages, even in API calls when it wasn't needed. This could be very
slow in some cases. Refactor so that total_pages isn't calculated unless
it's called.
While we're at it, refactor to condense all the sequential vs. numbered
pagination logic into one module. This incidentally fixes a couple more
bugs:
* "page=b0" returned all pages rather than nothing.
* Bad parameters like "page=blaha123" and "page=a123blah" were accepted.
In xml responses, if the result is an empty array we want the response
to look like this:
<posts type="array"/>
not like this (the default):
<nil-classes type="array"/>
This refactors controllers so that this is done automatically instead of
having to manually call `@things.to_xml(root: "things")` everywhere. We
do this by overriding the behavior of `respond_with` in `ApplicationResponder`
to set the `root` option by default in xml responses.
Refactor to use `render_error_page` to handle User::PrivilegeError
exceptions. This way these exceptions are logged to New Relic.
Changes:
* Anonymous users aren't automatically redirected to the login page.
Instead they're taken to the access denied page, which links to the
login/signup pages.
* JSON/XML error responses return `message` instead of `reason`.
* Refactor api_check to use render_error_page so that api limit errors
get logged to New Relic for analysis.
* Also standardize json error responses to return the error message in
`message` instead of `reason`.
Fixes POST/PUT API requests failing with InvalidAuthenticityToken errors
due to missing CSRF tokens.
CSRF protection is only necessary for cookie-based authentication. For
non-cookie-based authentication we can safely disable it. That is, if
the user is already passing their login + api_key, then we don't need
to additionally verify the request with a CSRF token.

* Simplify code.
* Show backtraces for all users, not just builders.
* Show backtraces only for unexpected server errors (status 5xx), not
for normal client errors (status 4xx).
* Log expected errors at info level (reduce noise in production logs).
Make <role>_only methods check the role first and ip bans last. This
avoids hitting the database for anonymous users, since they'll always
fail the is_<role>? check before the ip check.
