[Phlogiston Readers Web] Several tasks appear as Scope: Unknown in Status Report
Closed, ResolvedPublic

Description

It's not clear why there are so many "Unknown" scope tasks:

This is the first time Unknown is showing, and tasks that are included are tasks that should be hidden anyway, such as [T182319]. Thought maybe it was because there is a column exclusion line in the recat, and that column name was changed when the recat was not, but updating that did not affect this.

Event Timeline

@mmodell while debugging this bug, we traced it back to tasks that have no "Status" in the Phab<-->Phlogiston dump. Rows are appearing blank (instead of "open" or "resolved" etc). Are you aware of any changes to how the data is handled, particularly around the "Status" field? :)

@JAufrecht We might need to make time to look into this more, reports are still not useful. :)

More test data: T182197 has Scope = Unknown bug in report but it does have a status in the report.

Dev looks good now, but production is still showing Unknown areas in Scope. @JAufrecht my understanding was that we pushed the code to production and wanted to wait overnight to see if it changed anything before proceeding to Status = ''

Do we need to investigate why production hasn't changed?

Debugging update:
Test case T182639 had no parent in get_status_report. This was due to a design conflict. The stored procedure determines parenthood by checking the maniphest_blocked table for the final date of the report. However, the maniphest_blocked table, which is regenerated with each daily load, does not reconstruct historical blocking relationships from transactions. Instead, it gets the current parent state from the task data, and loads that into maniphest_blocked with the load date. So these relationships will only work in Status Reports if the report is run on the most recent day. This was fixed by having the stored procedure get_status_report not filter by date, so that it does get the parent match.

With this done, the test case turned out to be in a surprising but valid initial condition: it has a parent, but the parent is not in the reported project (Project Readers-Web-Kanbanana-Board), so there still should not be a previous parent status, so "Screep" is the correct value for Scope. However, Scope was displaying "Unknown". The relevant code in get_status_report is

CASE WHEN q2.previous_status IS NULL
      AND q2.parent_previous_status = 'open'  THEN 'Elaborated'
     WHEN q2.previous_status IS NULL          THEN 'Screep'

but parent_previous_status was not null, it was '', so these CASEs were not triggered and the case fell through to the default 'UNKNOWN'. The code was changed to check for empty string as well.

CASE WHEN q2.previous_status IS NULL or q2.previous_status = ''
      AND q2.parent_previous_status = 'open'  THEN 'Elaborated'
     WHEN q2.previous_status IS NULL or q2.previous_status = ''
                                              THEN 'Screep'

Unknowns are gone, but Scopes seem incorrect.

This task is shown as In-Scope, but should be Screep I think: https://phabricator.wikimedia.org/T182319

Same: https://phabricator.wikimedia.org/T182321

This one is elaborated but should be Screep too, I think: https://phabricator.wikimedia.org/T183151
