Hi Hon-Kie,

> Only one of them has published resources - the others do not.

Whether or not an author has published resources is not especially  
relevant, since we want to be able to move authoring spaces for  
authors to the correct domain on a multi-domain server, regardless of  
whether they have published anything.

The issue here is that there is incorrect data in the GDBM file:
on your server.

That file contains fsu author role entries for the following fsuK12  
domain users:


which should not be there.

There are no author role entries for those same users in the  
corresponding GDBM file for the fsuK12 domain:


(which actually makes sense, based on role creation and log-in history  
-- see below).

Anyway, as a consequence of this bizarre situation, the interactive  
move_construction_spaces.pl script determined these four users were  
solely fsu authors, and as a result did not prompt you to choose a  

The role start times recorded in fsu/nohist_domainroles.db for those  
four users are strange namely:

Thu Jun 5 08:04:11 am 2008 (EDT)
Thu Jun 5 08:22:13 am 2008 (EDT)
Thu Jun 5 08:28:57 am 2008 (EDT)
Thu Jun 5 08:30:46 am 2008 (EDT)

whereas the expected values would be:

Wed Mar 17 04:29:38 pm 2004 (EST)
Wed Jun  9 04:23:12 pm 2004 (EDT)
Thu Oct 13 02:50:04 pm 2005 (EDT)
Tue Dec 21 02:08:36 pm 2004 (EST)

if these corresponded to the start times for those author roles in the  
fsuK12 domain.

The solution here is to clean up the nohist_domainroles.db files for  
the fsu domain before running the move_construction_spaces.pl script.  
I will contact you off-list, to provide you with a script to do that.

To my knowledge there are four multi-domain servers in the LON-CAPA network:
loncapa10.fsu.edu, educog.com, capa4.phy.ohiou.edu, and loncapa.mit.edu.

I tested authoring space migration on educog.com some months ago and  
saw no issues in moving spaces for 702 authors in 140 domains, and  
Mark Lucas reported authoring space migration worked OK on capa4 a few  
weeks ago.

Checking nohist_domainroles.db files on educog.com I see no  
inconsistencies of the type seen for the fsuK12 domain.

Use of nohist_domainroles.db was included for the first time in  
LON-CAPA rev. 2.1.0 (December 2005). Population of that GDBM file  
occurs at role assignment, and also when a user logs-in.

According to the activity.log data for these four users, it is not  
unsurprising that there are no entries in  
given that the last log-ins are recorded as follows:

Thu Mar 18 07:31:10 2004
Wed Jun  9 16:24:18 2004
Thu Oct 13 14:50:26 2005
Thu Feb 10 16:09:07 2005

What is odd, however, are that the datestamps for the spurious entries  
in /home/httpd/lonUsers/fsu/nohist_domainroles.db are all from June 5,  
I do wonder what was going on that day (I would expect you would have  
been running LON-CAPA 2.6.3 at that time).

For those who are interested the logic in move_construction_spaces.pl  
is as follows:

(a) author role information is retrieved from the  
nohist_domainroles.db GDBM file in /home/httpd/lonUsers/<domain> for  
each domain hosted on that library server.

(b) If the same username is used for an author from more than one  
domain then you are prompted to either skip that username, or choose  
from one of the domains.

(c) If there is a directory: /home/<username>/public_html (the  
pre-2.11 location of Authoring Spaces), and <username> was not found  
in nohist_domainroles.db for any domains, then, at that stage a check  
is made for publications in /home/httpd/html/res to determine the  
user's domain.

(d) If we still don't know the domain, then roles.db files for  
<username> are checked for all domains hosted on the server, to look  
for au roles for that user.

(e) If we still don't know the domain, then a query (username =  
'<username>') is made to the allusers MySQL table.

(f) If we still don't know the domain, then a message will be  
displayed: "WARNING: <username> has no domain" and you will be  
prompted to skip, or enter a domain.
