Grouper Users - Open Discussion List

[Chris Hyzer <>]

The grouper_members table is used for foreign keys, so an assumption we have 
made while developing Grouper is the rows in grouper_members are never 
deleted unless there is a member_change_subject operation.  So, I think the 
solution is that the unresolvable subject deletion utility (and subsequently 
grouper report) should look for subjects used in memberships, not subjects in 
grouper_members.  I think that would solve your problem.  There are a bunch 
of other solutions to this, we should discuss at some point for some release 
after 1.6.0...

Thanks,
Chris

Subject: [grouper-users] Fails to deleting group from grouper_members when 
the group is deleted

Greetings,

The grouper report emails are very helpful, thanks for that. I noticed 
that our unresolvable g:gsa subjects keeps increasing, so I 
investigated. In our environment, it seems that grouper does not delete 
groups from grouper_members table even though the group has been deleted 
from grouper_groups. See below for the steps I used to reproduce:

1) Starting with a (nearly) minimal registry:

mysql> select id,name from grouper_groups;
+----------------------------------+-----------------+
| id                               | name            |
+----------------------------------+-----------------+
| 28f66ed34b03407b9525d8b23ce6603a | etc:wheel       |
| 7621b985460f4fbcb9521e49203b261d | etc:provisioner |
+----------------------------------+-----------------+

mysql> select subject_id,subject_type from grouper_members;
+----------------------------------+--------------+
| subject_id                       | subject_type |
+----------------------------------+--------------+
| GrouperSystem                    | application  |
| 28f66ed34b03407b9525d8b23ce6603a | group        |
| GrouperAll                       | application  |
| 7621b985460f4fbcb9521e49203b261d | group        |
+----------------------------------+--------------+

2) Add a group using GSH, then check these two tables again:

gsh 0% addGroup("etc", "test", "test")
group: name='etc:test' displayName='etc:test' 
uuid='b7e6c819cc8a4bca84b99a92df097325'

mysql> select id,name from grouper_groups;
+----------------------------------+-----------------+
| id                               | name            |
+----------------------------------+-----------------+
| 28f66ed34b03407b9525d8b23ce6603a | etc:wheel       |
| 7621b985460f4fbcb9521e49203b261d | etc:provisioner |
| b7e6c819cc8a4bca84b99a92df097325 | etc:test        |
+----------------------------------+-----------------+
mysql> select subject_id,subject_type from grouper_members;
+----------------------------------+--------------+
| subject_id                       | subject_type |
+----------------------------------+--------------+
| GrouperSystem                    | application  |
| 28f66ed34b03407b9525d8b23ce6603a | group        |
| GrouperAll                       | application  |
| 7621b985460f4fbcb9521e49203b261d | group        |
| b7e6c819cc8a4bca84b99a92df097325 | group        |
+----------------------------------+--------------+


3) delete the group using GSH, then check the two tables again:

gsh 1% delGroup("etc:test")
true
mysql> select id,name from grouper_groups;
+----------------------------------+-----------------+
| id                               | name            |
+----------------------------------+-----------------+
| 28f66ed34b03407b9525d8b23ce6603a | etc:wheel       |
| 7621b985460f4fbcb9521e49203b261d | etc:provisioner |
+----------------------------------+-----------------+
mysql> select subject_id,subject_type from grouper_members;
+----------------------------------+--------------+
| subject_id                       | subject_type |
+----------------------------------+--------------+
| GrouperSystem                    | application  |
| 28f66ed34b03407b9525d8b23ce6603a | group        |
| GrouperAll                       | application  |
| 7621b985460f4fbcb9521e49203b261d | group        |
| b7e6c819cc8a4bca84b99a92df097325 | group        | <--- It is still there?
+----------------------------------+--------------+

Do I need to make an additional command to grouper?

As an aside, USDU seems unable to delete these, even with the -delete 
option.
