runner_on_start events have zero-length strings for their stdout
fields. We don't want to display these in the ui so we omit them.
Although the stdout field is an empty string, it still has a recorded
line length of 1 that we must account for. Since we're not rendering
the blank line, we must also go back and set the event record's line
length to 0 in order to avoid deleting too many lines when we pop or
shift events off of the view while scrolling.
When jobs are still processing events, the UI uses numerical ranges
based on job_event.counter instead of page numbers. We can't apply
search filters in this state because then there would be no way to
distinguish between events that are missing due to being filtered out
by search and events that are missing because they're still being
processed.
The UI must be able to distinguish between the two types of missing
events because their absence is presented differently. Events that are
filtered out by a search query have no visual representation, while
events that are missing due to event processing or other causes are
displayed as clickable "..." segments.
When the page loads, we want to retrieve and initially display enough
content for the scrollbar to show. If the very last page doesn't
have enough content for the scrollbar to show, the user won't be able
to scroll up to see more job history. To avoid this scenario, we always
fetch the last _two_ pages when loading the view.
THis commit imroves conditional rendering of the container groups form for
System Auditors. It also removes a ng-class condition in the IG list that was unused.
This allows the System Auditor to see the container groups form in a disabled state.
If the pod_spec_override has been changed that field will be open when the page renders
but it will be disabled. It also greys out all code mirror text area fields for System Auditor.
It adds the correct url for the Container Groups message bar to inform users of possible
pitfalls associated with that feature.
