Plugin fails to work with Trac version 1.2.3

Reported by: Richard V Owned by: Ryan J Ollos
Priority: normal Component: LdapAuthStorePlugin
Severity: critical Keywords:
Cc: Trac Release: 1.2


The plugin needs maintenance to make it work with Trac version 1.2.3. It crashes because the Enviroment class changed and the functions "get.db_cnx()" have been removed and replaced by "db_query" or db_transaction" respectively.

So when you try to login, the plugin crashes. The log is the following:

Traceback (most recent call last):

    valid = store.check_password(user, password)

    db = self.env.get_db_cnx()
AttributeError: 'Environment' object has no attribute 'get_db_cnx'

I have managed to fix the problem by replacing self.env.get_db_cnx() in line 253 with with self.env.db_transaction as db: and remove the db.commit() calls. I would like to help out and upload the fix. How do I have access to the source repository?

You could adopt the plugin. I don't run trac anymore.

I don't have a configuration for testing, but I can put together an untested patch if you are willing to test it out on your end.

Sorry for the late reply, I lost my login name and password and needed to figure out what was it. Regarding the patch, I am willing to test it out on my end. But like I mentioned in the original report, I have fixed the problem already by changing the code at the lines that I mentioned above.
