KeyError: acct_mgr.web_ui after failed import of acct_mgr.web_ui

[andhos@…]

This happens in Trac 0.12.2 After installing AccountManager Plugin this error appears when I navigate to the plugins page in the admin or if I enable the acct_mgr.web_ui.LoginModule.

KeyError: acct_mgr.web_ui

Certainly you did comply to the explicit advice for configuration and disabled Trac's own web login page, didn't you?

[components]
acct_mgr.web_ui.LoginModule = enabled

trac.web.auth.LoginModule = disabled

What version of AcctMgr did you (try to) install exactly? Where did you take the error message from, the browser window, a error message box, trac.log, ...? I'll need something more to reproduce, if it's not an installation and configuration issue at your side.

Trac: fresh install of 0.12.2, in a virtualenv with --no-site-packages setup with apache and mod_wgsi. AccountManagerPlugin: trunk version.

Scenario 1

• Installed the plugin but not enabled anywhere
• Everything works fine in normal pages
• When navigating to the plugin page in web admin
• Error appears in plugin page

Scenario 2

• Installed the plugin and enabled the plugin in trac.ini
• Yes, trac.web.auth.LoginModule was disabled
• Error appears in all pages

Error is found in /var/log/apache2/trac-error.log which I setup to log trac errors according to ​this guide.

I will post a trac log as soon as possible.

Same situation here, fresh Trac 0.12.2 install.

Okay, here is the Trac Exception:

I just did a new install, Ubuntu 11.04, linux kernel 2.6.38-8-generic x86_64 Python 2.7.1+ Babel 0.9.5 Trac 0.12.2 AccountManagerPlugin trunk

These are my exact commands: :~$ virtualenv --no-site-packages ~/tracenv :~$ source ~/tracenv/bin/activate (tracenv):~$ easy_install Babel==0.9.5 (tracenv):~$ easy_install Trac (tracenv):~$ mkdir ~/trac (tracenv):~$ trac-admin ~/trac/test (tracenv):~$ tracd --port 8000 ~/trac/test # test, it works (tracenv):~$ easy_install https://trac-hacks.org/svn/accountmanagerplugin/trunk (tracenv):~$ tracd --port 8000 ~/trac/test # test, plugin page doesn't work

I haven't tried after enabling the plugin but I'm pretty sure the same will happen just like last time.

I am also going to test with python 2.6 a little later. Thanks

Sorry about the previous post, here are the commands correctly formatted.

These are my exact commands:

:~$ virtualenv --no-site-packages ~/tracenv
:~$ source ~/tracenv/bin/activate
(tracenv):~$ easy_install Babel==0.9.5
(tracenv):~$ easy_install Trac
(tracenv):~$ mkdir ~/trac
(tracenv):~$ trac-admin ~/trac/test
(tracenv):~$ tracd --port 8000 ~/trac/test # test, it works
(tracenv):~$ easy_install https://trac-hacks.org/svn/accountmanagerplugin/trunk
(tracenv):~$ tracd --port 8000 ~/trac/test # test, plugin page doesn't work

Ok, silly me. This is a regression caused by the config.get* calls introduced in changeset [10169].

Your quote from log file was just a result of failed import of acct_mgr.web_ui module. Lessons learned:

1. Do (better) testing of any change, how trivial it might ever look.
2. Check beginning with

   -------------------------------- environment startup [Trac 0.13dev] --------------------------------
   

Sorry, this will be fixed in a few minutes. I leave it up to you to close this ticket, if you can confirm that the issue is really fixed for you too.

[Steffen Hoffmann]

(In [10176]) AccountManagerPlugin: Fix reading of configuration in LoginModule, refs #8774.

This is a rework of changeset [10169] which added some reportedly broken code. Now we use module variables instead of that defined on class level. This should even work with Trac < 0.12, where the requested values are not defined.

[andhos@…]

I have updated and checked that it indeed works.

Thank you very much.

[Steffen Hoffmann]

Glad to hear that. Thank you for taking care by instant report and testing the fix.
