In order to continue supporting the legacy ACL system, we replace
the 500 error from a non-existent `self` endpoint with a response of a
`null` `AccessorID` - which makes sense (a null AccessorID means old
API)
We then redirect the user to the old ACL pages which then gives a 403
if their token was wrong which then redirects them back to the login page.
Due to the multiple redirects and not wanting to test the validity of the token
before redirecting (thus calling the same API endpoint twice), it is not
straightforwards to turn the 'faked' response from the `self` endpoint
into an error (flash messages are 'lost' through multiple redirects).
In order to make this a slightly better experience, you can now return a
`false` during execution of an action requiring success/failure
feedback, this essentially skips the notification, so if the action is
'successful' but you don't want to show the notification, you can. This
resolves showing a successful notification when the `self` endpoint
response is faked. The last part of the puzzle is to make sure that the
global 403 catching error in the application Route also produces an
erroneous notification.
Please note this can only happen with a ui client using the new ACL
system when communicating with a cluster using the old ACL system, and
only when you enter the wrong token.
Lastly, further acceptance tests have been added around this
This commit also adds functionality to avoid any possible double
notification messages, to avoid UI overlapping
In some circumstances a consul 1.4 client could be running in an
un-upgraded 1.3 or lower cluster. Currently this gives a 500 error on
the new ACL token endpoint. Here we catch this specific 500 error/message
and set the users AccessorID to null. Elsewhere in the frontend we use
this fact (AccessorID being null) to decide whether to present the
legacy or the new ACL UI to the user.
Also:
- Re-adds in most of the old style ACL acceptance tests, now that we are keeping the old style UI
- Restricts code editors to HCL only mode for all `Rules` editing (legacy/'half legacy'/new style)
- Adds a [Stop using] button to the old style ACL rows so its possible to logout.
- Updates copy and documentation links for the upgrade notices
