+-- Evergreen DB patch XXXX.data.fix_long_overdue_perm.sql
+--
+-- Update permission 549 to have a "code" value that matches what
+-- the Perl code references
+--
+BEGIN;

+-- check whether patch can be applied
+SELECT evergreen.upgrade_deps_block_check('XXXX', :eg_version); -- jeff
+
+-- For some time now, the database seed data / upgrade scripts have created
+-- a permission with id 549 and code COPY_STATUS_LONGOVERDUE.override, while
+-- the Perl code references a permission with code
+-- COPY_STATUS_LONG_OVERDUE.override
+--
+-- Below, we attempt to handle at least three possible database states:
+--
+-- 1) no corrective action has been taken, permission exists with id 549 and
+-- code COPY_STATUS_LONGOVERDUE.override
+--
+-- 2) permission with id 549 has already been updated to have code
+-- COPY_STATUS_LONG_OVERDUE.override
+--
+-- 3) new permission with unknown id and code COPY_STATUS_LONG_OVERDUE.override
+-- has been added, and potentially assigned to users/groups
+--
+-- In the case of 3, users and groups may have been assigned both perm id 549
+-- and the local permission of unknown id.
+--
+-- The desired end result is that we should have a permission.perm_list
+-- entry with id 549 and code COPY_STATUS_LONG_OVERDUE.override,
+-- any locally-created permission with that same code but a different id
+-- is deleted, and any users or groups that had been granted that locally-created
+-- permission (by id) have been granted permission id 549 if not already granted.
+--
+-- If for some reason the permission at id 549 has an unexpected value for "code",
+-- the end result of this upgrade script should be a no-op.
+
+-- grant permission 549 to any group that
+-- has a potentially locally-added perm
+-- with code COPY_STATUS_LONG_OVERDUE.override
