From 32798dcfdb00662a640f0ff2915766591d21e287 Mon Sep 17 00:00:00 2001 From: Jonathan Tan Date: Thu, 12 Jul 2018 10:58:28 -0700 Subject: [PATCH] Always send refs' objects despite "filter" in pack In a0c9016abd ("upload-pack: send refs' objects despite "filter"", 2018-07-09), Git updated the "filter" option in the fetch-pack upload-pack protocol to not filter objects explicitly specified in "want" lines, even if they match the criterion of the filter. Update JGit to match that behavior.
