#2815 closed defect (fixed)

Cannot upgrade after install leads to ImportError: No module named path error

Reported by: seeker136@… Owned by: Colin Guthrie
Priority: normal Component: WorkLogPlugin
Severity: normal Keywords:
Cc: Trac Release: 0.11


I installed worklog from svn (0.11) using easy_install script. Everything seemed to work ok, but after enabling the plugin in trac.ini and performing upgrade using trac-admin I get the following message:

Database is up to date, no upgrade necessary.

If I ignore the message, restart my web server and navigate to my project, I get the following message:

That bit of the file is pretty standard. I just copied it from other plugins, so I'm guessing either b2 has broken the plugin/template API or there is something wrong with your setup tools.

I'm running with Trac trac:r6097 with no problems.

I've been meaning to bring everything up-to-date tho', so I'll try and see if I can reproduce sometime soon. In the mean time let me know if you solve it.

I went from a ubuntu 6.6 to 6.10 and encouter the same problem now. The problem might be related to this bug in ubuntu updgrade as this error was encoutered during the upgrade:

comment:4 Changed 10 years ago by Colin Guthrie

(In [3483]) Update the Admin pages to the new Trac API. Not really tested this but at least the plugin loads now. Will do more testing shortly. Fixes #2834, Refs #2815 - Can the reporters please check the status of #2815 and close if appropriate. It's not quite the same error as #2834 but it looks as if it could be related. Thanks.

I'm hit by the same problem.

When I upgraded Trac from 0.11b1 to 0.11b2, I lost the work log admin settings page (just showed the worklog page), and Stop work didn't ask for a message anymore.

I then upgraded worklog to current 0.11 trunk (revision 3565) and got the error reported above.

Oh, and I have a stock Debian 4.0 Etch setup with Python 2.4, running tracd stand-alone.

comment:7 Changed 10 years ago by Colin Guthrie

Can you enable logging please and give me a full trace (including the reasons why the plugin could not be loaded (e.g. from the beginning of a restart). Thanks.

The attachmend above contains all log output from a tracd restart up to the error described above.

Note that even though I have other plugins as seen in the log, I disabled them for this particular trac project.

I checked out the worklog 0.11 source and tried importing it in the Python interpreter:

Python 2.4.4 (#2, Apr  5 2007, 20:11:18)

Might have something to do with this? (0.11b2 was revision 6685)

I'll try with Trac current trunk.

comment:11 Changed 10 years ago by Colin Guthrie

OK, this is the key failure:

2008-04-28 13:17:01,931 Trac[__init__] ERROR: Skipping "worklog = worklog": (can't import "cannot import name TicketAdminPanel")

Which is generated from:

from trac.ticket.admin import TicketAdminPanel


I can't say why this is happening.

In Trac trunk it has the following definition:

trac/ticket/ TicketAdminPanel(Component):

So I can't think why you cannot access it unless your trunk is out of date (does b2 have this change? I think it should... perhaps you have some weird egg cache thing going on?) :s

comment:12 Changed 10 years ago by Antti Kaihola

Updated Trac to trunk, now works correctly. Apparently the TicketAdminPage to TickeAdminPanel rename has occurred after 0.11b2.

But still no Work Log admin page. If I go to /admin/ticket/worklog, I get exactly the same page as from /worklog (the work log summary).

Sorry for the delays, but I've eventually fixed the final problem with [5022]. Better late than never ;)
