Confluence upgrade from 5.1.5 to 5.2.3 fails

Hi there

I'm trying to upgrade my Confluence installation from 5.1.5 to 5.2.3 but this fails with the following output on the log:

Even reverting database and home directory and start again results in the same. Any ideas what's wrong and how to fix it?

Switched over to a support ticket as the problem seems to be more complex.

Most likely you are hitting this known bug of upgrade failure affecting MySQL database: https://jira.atlassian.com/browse/CONF-30380

Follow through the diagnosis section to determine which workaround would be applicable to your case and execute it accordingly. That should help to remedy the problem.

Hi Hanis,

thx for your hint which brings me a big step ahead. The storage engine was correct but I had to convert the collation of nearly all tables to utf8_bin.

But now I got another error during start, see Confluence_5.1.5_5.2.3_error.txt. What to do now with the duplicate entry?

Kind regards,

Yves

Caused by: org.springframework.dao.DataIntegrityViolationException: StatementCallback; SQL [UPDATE logininfo SET USERNAME = COALESCE((SELECT um.user_key FROM user_mapping um WHERE logininfo.USERNAME = um.lower_username), logininfo.USERNAME)]; Duplicate entry '0b94489740e078d60140e07a07cc001b' for key 'USERNAME'; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry '0b94489740e078d60140e07a07cc001b' for key 'USERNAME'

Bsed on the error, there are duplicate rows in your LOGININFO table that are preventing the upgrade task.

Run the following query:

select username from logininfo group by username having count(username)>1;

If it returns any rows, you are affected by this issue and the resolution is:

  1. Stop Confluence.
  2. Take a backup of your database.
  3. Run the following queries against your database:

    create temporary table deleteset as select username from logininfo group by username having count(username)>1;
     
     
    delete from logininfo where username in (select username from deleteset);

    (warning) We highly recommend that you run the queries against a test instance/database before attempting to do so on your production data.

Hi

Hm, seems to me that this is not the case. There are no duplicates on this table, see ConfluenceLoginInfoTable.txt. Strange. Should I try the update again?

Kind regards,

Yves

Hi

Tried again because the mentioned query shows this:

mysql> select username from logininfo group by username having count(username)>1;
Empty set (0.00 sec)

Unfortunately the error is still the same, see Confluence_5.1.5_5.2.3_error2.txt. So what should I do now?

Kind regards,

Yves

Thx for the idea but that's not the case. Checked it on the DB dump and there are only entries like ENGINE=InnoDB. Other ideas?

Hi Yves,

It seems that you are encountering a known issue which is describe on our published knowledge base article here:

https://confluence.atlassian.com/pages/viewpage.action?pageId=393904718

Hope it helps.

Cheers,
Septa Cahyadiputra

Hi Septa,

thx for the link. On my confluence.cfg.xml I have a complete different value:

<property name="hibernate.dialect">com.atlassian.hibernate.dialect.MySQLDialect</property>

The kb article references SQLServer but we use MySQL. How to go ahead?

Kind regards,

Yves

Hi Yves,

Seems like this is due to the previously mentioned KB although the cause is a bit different. You might want to check the following configuration:

  • my.ini/cnf contain default-character-set=utf8
  • Ensure that the MySQL driver used is correct

Checked each tables using

SELECT TABLE_SCHEMA,
       TABLE_NAME,
       CCSA.CHARACTER_SET_NAME AS DEFAULT_CHAR_SET,
       COLUMN_NAME,
       COLUMN_TYPE,
       C.CHARACTER_SET_NAME,
       ENGINE
  FROM information_schema.TABLES AS T
  JOIN information_schema.COLUMNS AS C USING (TABLE_SCHEMA, TABLE_NAME)
  JOIN information_schema.COLLATION_CHARACTER_SET_APPLICABILITY AS CCSA
       ON (T.TABLE_COLLATION = CCSA.COLLATION_NAME)
 WHERE TABLE_SCHEMA=SCHEMA()
   AND C.DATA_TYPE IN ('enum', 'varchar', 'char', 'text', 'mediumtext', 'longtext')
 ORDER BY TABLE_SCHEMA,
          TABLE_NAME,
          COLUMN_NAME;

All things fails, better consult with our support team so we could investigate the issue thoroughly.
