Two-way syncing of open/closed status between cards and bugs

[floatingatoll]

Handle this, rather than complaining about this.

This error message:

"Bug 1234567 is not RESOLVED (NEW) but card 1234 says Done"

stems from this decision that hasn't been made since the initial development of this script:

+    # XXX: Should we close bug on card completion?
+    if ($bug_status ne "RESOLVED" and $card_status eq "Done") {
+       warn "Bug $bug->{id} is not RESOLVED but card says $card_status"; 
+    }

Let's decide.

This problem turns out to be joined to the flipside problem: "What should happen when a bug is reopened?"

And that models precisely as the Assignee syncing problem does, as follows:

Each of these change possibilities is "initial state -> user-modified state -> kanbanize-synced state"

• Bug Open, Card Open -> Bug Closed -> Card Closed
• Bug Open, Card Open -> Card Closed -> Bug Closed
• Bug Closed, Card Closed -> Bug Opened -> Card Opened
• Bug Closed, Card Closed -> Card Opened -> Bug Opened

We detected the user-modified state using the history timestamps to compare against the last state change of the eventual target of the sync.

There are four actions possible for the script to take here:

• Card Closed \ Implemented. When a bug is resolved, the script should move the card to the Done column, clearing any blockers along the way.
• Card Opened \ Not implemented. When a bug is reopened, the script should ensure that a card associated with the bug exists outside of the Done/Archive columns. Since we cannot arbitrarily move cards back into someone's sprint without triage, I propose that we simply create a new card. The old card will be ignored entirely.
• Bug Closed \ Not implemented. When a card is closed, the script should ensure that the associated bug is marked as resolved. This is not particularly difficult and resolves a user-perceived syncing error.
• Bug Opened \ Not implemented. When a card is created or opened, the script should ensure that the associated bug is not resolved, reopening it if necessary.

With these four decisions in place, all open cards should reference only open bugs. Reopened bugs will be treated as new work, which appropriately reflects how they must be treated in the sprint scheduling as well.
