Subject: Fix proximity adjustment calculator
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=70cde9a407f47234c424d96c8db289c45b4503a2;p=working%2FEvergreen.git

Fix proximity adjustment calculator

The canonical use case for proximity adjustment is to use it broadly
to effect the local proximity of items within a particular area, in
a like manner, across many parts of the org tree.  However, in cases
where it is lightly used, or used with non-overlapping criteria columns,
there are cases where the adjustment will spread beyond its intended
range of influence.

The changes here create a much stricter and correct test for rule
matching, which will end in the correct choice of rules in all cases.
