Hi Àlex,
Sorry for this late reply.
I need a larger extract of your logs to be able to help and probably more
later. You may send it to me privately if you prefer.
Regards,

Hi,
I'm trying to upgrade from XWiki 3.1 to 4.4, but I'm having problems with
the data migration process.
It all goes well up until R40000XWIKI6990, which fails due to a duplicate
key (see below, full Tomcat log also attached). It also fails with safemode
enabled.
ERROR o.h.u.JDBCExceptionReporter - ERROR: duplicate key value violates
unique constraint "xwikidoc_pkey"
I've tried running SQL commands from XWIKI-8129 [1] jira issue too, but
it doesn't apply any modification in my case. So it doesn't make any
difference.
Older version of XWiki in-between also fail.
The system set up is:
Fedora 14 (x86_64)
Java 1.6.0_20 -- OpenJDK Runtime Environment (IcedTea6 1.9.10)
Tomcat 6
PostgreSQL 8.4.9
XWiki 3.1 (upgraded from 2.2.1 and with no configuration options changes)
Any idea of how to solve this problem?
Thanks,
Àlex

Hi Denis,
I finally got it solved yesterday. I was able to find the database
record that made the migration process fail by rising the log level to
debug. I'll explain in case someone else finds a similar problem.
The problem was a wiki page that somehow got duplicated or created
twice, but with a slightly different name. Moreover, although the two
database records had different document ids, the id migration process
assigned the same final id for both of them. The records look like this
in the database:
xwd_id | xwd_fullname | xwd_name |
xwd_title |
----------+------------------------------------------+----------+------------------------------------+
292584123 | Main.Cursos per a professorat 2011.2012 | 2012 | Cursos
per a professorat 2011/2012 |
971984561 | Main\.Cursos per a professorat 2011.2012 | 2012 | Cursos
per a professorat 2011/2012 |
xwd_date | xwd_content_update_date | xwd_creation_date |
xwd_author | xwd_content_author
---------------------+-------------------------+---------------------+---------------+--------------------+
2011-10-25 20:30:10 | 2011-10-25 20:30:10 | 2011-08-26 13:30:42 |
XWiki.user1 | XWiki.user1
2012-11-12 11:25:30 | 2012-11-12 11:25:30 | 2011-12-13 15:41:49 |
XWiki.user2 | XWiki.user2
xwd_creator | xwd_web | xwd_version |
xwd_parent
----------------+------------------------------------+-------------+-------------
XWiki.user2 | Main.Cursos per a professorat 2011 | 146.1 |
Main.BETSEA
XWiki.user1 | Main.Cursos per a professorat 2011 | 22.1 |
Main.BETSEA
The rest of the fields either have the same values or are empty. As can
be seen in xwd_fullname, it looks like the dot on the page name might
have confused XWiki. In fact, if get to the page from the web interface,
the name of the page is "2012". It is as if XWiki had split the name at
the "." and had taken the previous string as the space name. The URL
looks like this:
http://intranet-sbd.udl.cat/xwiki/bin/view/Main.Cursos+per+a+professorat+2011/2012
and in the toolbar the following appears:
SPACE: Main.Cursos per a professorat 2011
PAGE: 2012
This is for the first record in the database. I couldn't access the
second one from the web interface.
By deleting the page corresponding to the first record, the migration
process finishes without problems. Now I'd like to instead remove the
references to the second page from the database. Would it be enough to
remove the entries with the following commands?
delete FROM xwikidoc where xwd_id=292584123;
delete FROM xwikiattachment where xwa_doc_id=292584123;
delete FROM xwikilinks where xwl_doc_id=292584123;
delete FROM xwikircs where xwr_docid=292584123;
If you think this might be a bug that should be solved, I still can send
the logs or provide any information needed.
Thanks,
Àlex
