+BUG-21: the datastructure of dir/files is actually quite broken on a real import (seems to be on second/subsequent imports -- the code to remove deleted files, is not 'seeing all files?'
+pa=# select count(edl.dir_eid), d.path_prefix from entry_dir_link edl, dir d where edl.dir_eid = d.eid and edl.dir_eid in ( select eid from dir ) group by d.path_prefix;

+SO FILE counts are really broken, a slight bit off on a couple of dirs, but say M51, its 675 in DB, and the file tree walk saw 2400 -- and an ls -lR confirms...
+
+
+checking by hand for the first file in M51 dir:
+
+ddp@mara:~/src/photoassistant$ ls -l /export/docker/storage/photos/CAM_UPLOADS/M\'s\ Galaxy\ A51/Camera\ Roll/20190105_175219.jpg

+
+pa=# select * from entry where name = '20190105_175219.jpg';
+ id  |        name         | type_id | exists_on_fs
+-----+---------------------+---------+--------------
+ 951 | 20190105_175219.jpg |       2 | t
+(1 row)
+
+pa=# select * from entry_dir_link where entry_id = 951;
+ entry_id | dir_eid
+----------+---------
+      951 |       3
+(1 row)
+
+pa=# select * from dir  where eid = 3;
+ eid |                 path_prefix                  | num_files | last_import_date
+-----+----------------------------------------------+-----------+-------------------
+   3 | static/CAM_UPLOADS/Mandy's Phone/Camera Roll |      2999 | 1613024872.385247
+
+
+so the file is really in the M51 dir, but is in the DB in Mandy's phone dir instead...
