you are debugging pack bitmaps.
+pack.useSparse::
+ When true, git will default to using the '--sparse' option in
+ 'git pack-objects' when the '--revs' option is present. This
+ algorithm only walks trees that appear in paths that introduce new
+ objects. This can have significant performance benefits when
+ computing a pack to send a small change. However, it is possible
+ that extra objects are added to the pack-file if the included
+ commits contain certain types of direct renames.
