Failed to create environment. 'unicode' object has no attribute 'decode'

[cyrano423@…]

I attempted to upgrade from 0.10.3 stable to the latest 0.10.4dev branch. Running:

trac-admin [projenv_path] upgrade

However, that failed. So I attempted to initialize a new environment:

trac-admin [projenv_path] initenv

which also failed. I then attempted to do a clean install of 0.10.4dev. No dice. Then, converted the MySQL database:

mysql> ALTER DATABASE trac DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

Confirmed it with:

mysql> use trac
mysql> SHOW VARIABLES LIKE '%character%';

Each time the error message was the same. The output is:

Thank you very much for your time.

Reinstalled everything from scratch (trac, clearsilver, subversion, mysql-python, etc) and the error output is the same. For now I've disabled the trac server as when loading the page 'cgitb' prints out the database username and password.

#5069 describes another symptom of this problem. The problem was introduced in r5136 which assumed that the db string should be an unicode string. I have to check why it isn't actually an unicode string, as that string is coming straight from the config options and therefore should be unicode…

Woops, the problem was rather me not reading the API doc for the unicode_unquote method ;-)

Thank you very much for looking into this. I truly appreciate it.

Fixed by r5162 (trunk) and r5163 (0.10-stable), thanks for the report!
