Changes
-------
The new patch "AMBARI-14574_Jan22.patch" has corrections for some failed test
cases.
Bugs: AMBARI-14574
https://issues.apache.org/jira/browse/AMBARI-14574
Repository: ambari
Description
-------
On installation wizard, multiple clicks on the "Next" button can cause skipping
of steps. The timing of the 2nd click decides if that click will be processed
again or not. The following JIRAs had the same issue:
AMBARI-7195
AMBARI-7315
The fix for the above issues helps to resolve most part of the problem. But if
the user happened to click again at the point when the last callback function
has just completed (and thus, has made the "Next" button clickable again) but
the next step has not yet completed its rendering, then the 2nd click gets
processed again. The "current step" was already updated in the code to point to
the next step, from the 1st click. So when this 2nd click calls the "next"
function in the router, the subsequent step of the "current step" gets set as
the current step. As a result we skip steps.

Testing
-------
CAUSE & FIX:
The issue is seen in most of the wizard installation steps because the
properties responsible to disable the duplicate submit calls are unable to
account for the transition between the 'actions' and 'render' queues used by
the Ember framework.
The installation steps use the 'submit' function from controllers or the 'next'
function from installer to set the properties used in the checks for processing
the Next button clicks. These properties are reset again in the views of next
step if it renders or in the same controller/installer in case of failures.
Hence, the property that is responsible for the checks must be accessible
across controllers, installer and views.
The fix proposed for this issue involves creating a new property
'nextBtnClickInProgress' in the router, hence accessible in all the above
places. This property is set at suitable places in the controller/installer. It
is reset in Views of all the 11 steps of the installation wizard and also at
appropriate places in some controllers (resetting for failure cases).
The following steps have been found to skip steps and have been fixed with the
required checks:
Step 1
Step 3
Step 4
Step 5
Step 7
TEST CASES:
The test cases check if multiple submit calls succeed in skipping subsequent
steps. This is verified by checking the status of router's transitions call
after each submit call. Since the router's 'next' function for a step is the
last step before the context changes its current step to point to the next
step, checking if a router has made this transition or not gives an indication
of whether the next step was transitioned or not.
There are 5 new tests added to test this scenario.
