Blog fra februar, 2014

Thursday night on the couch, having a day off friday, I decided to do some layout work on the Confluence we use at my workplace (just for the fun of it, as my work is my hobby - sort of anyway).

I had created a new User Macro, that I wanted to implement on the Dashboard, so I started editing in the Global Layouts in Confluence to place it on the Dashboard:

As part of the changing of the Dashboard code, I entered:

{html}<font size="4">Space Quick Select</font>{html}

pressed "Save" and:

the Confluence went down - just giving me a "Service Unavailable" from the Traffic Manager.

Shit, I restarted the instance- no improvement.....so starting to diagnose:

npn@docs01:~$ wget -O - localhost:8080
--2014-01-30 21:46:27--  http://localhost:8080/
Resolving localhost... ::1, 127.0.0.1

HTTP request sent, awaiting response... 500 Internal Server Error
2014-01-30 21:46:28 ERROR 500: Internal Server Error.

npn@docs01:~$

Hm, error 500, diagnosting further:

root@docs01:/pack/confluence-data/logs# tail -f atlassian-confluence.log
caused by: java.lang.RuntimeException: Error rendering template for decorator global
at com.atlassian.confluence.setup.velocity.ApplyDecoratorDirective.render(ApplyDecoratorDirective.java:186)

Was expecting one of:
    "," ...
    ")" ...
    <WHITESPACE> ...

at org.apache.velocity.Template.process(Template.java:141)

So, It seems the code I put in the Global layout makes the Confluence crash totally, not just rendering the Dashboard, but TOTALLY!!!

I fired up for MySQL and looked at the DECORATORS table:

mysql> select DECORATORID,DECORATORNAME FROM DECORATOR;
+-------------+-----------------------+
| DECORATORID | DECORATORNAME         |
+-------------+-----------------------+
|    64913409 | decorators/global.vmd |
|    48300036 | decorators/page.vmd   |
|    59080705 | decorators/page.vmd   |
+-------------+-----------------------+
3 rows in set (0.00 sec)

mysql>

Now, 2 choises are available:

Fix It
Delete the DECORATORID=64913409 record.

All though I am pretty sure number 2 works (same as using "Reset Default"), I went for number 1:

First, I shut down Confluence completely.

Then I made a complete dump of the Confluence Database:

mysqldump -uconfluence -p confluence > confluence.sql

After securing the backup, I dumped the DECORATOR table:

mysqldump -uconfluence -p confluence DECORATOR > DECORATOR.sql

After that, I changed the DECORATOR.sql file i the "vim" editor - stripping off everything but the record for DECORATORID=64913409, and change the "INSERT INTO" to an "UPDATE" so it looked like:

UPDATE DECORATORS SET body='### ...code...code...code.' WHERE  DECORATORID=64913409

And the whole point being that I removed the "{html}<font size=\"4\">Space Quick Select</font>{html}" from the body code.

Finally, I put back the decorator:

mysql -uconfluence -p confluence < DECORATOR.sql

And started the Confluence Instance:

- up and running again
