Hudons Trac Plugin: Trac[main] ERROR: iterable argument required

[ffidelis@…]

Hi there!

• I need some help when create the egg file (HudsonPlugin-0.3.py23.egg) generated version 0.10 r7165 from svn repo and install it in plugin directory in one project only called test and edited trac.ini file project adding parameters:

(...)
[components]
hudsontrac.* = enabled

[hudson] job_url = http://hostname:8080/hudson[[BR]] display_modules=true
main_page=/hudson/
display_in_new_tab=true
(...)

• After restart the services, when access the project page, I have a message like:

Traceback (most recent call last):

File "/usr/lib/python2.3/site-packages/trac/web/main.py", line 387, in dispatch_request

dispatcher.dispatch(req)

File "build/bdist.linux-x86_64/egg/HudsonTrac/HudsonTracPlugin.py", line 97, in get_navigation_items

TypeError: iterable argument required

• And I see that plugin is loaded sucessfully in trac.log, but when somebody access the page of project have the error "Trac[main] ERROR: iterable argument required":

Thanks for any help!

I'm not sure, but I think this may be related to trac 0.10 (I only have 0.11 instances to test). Try replacing line 97

        if self.nav_url and 'BUILD_VIEW' in req.perm:

with

        if self.nav_url and req.perm.has_permission('BUILD_VIEW'):

and similarly on lines 113 and 117, and let me know if that fixes it.

You are correct. Trac version is 0.10.

I replace the line 97 of HudsonTracPlugin.py for your suggestion and reinstall egg file and the project's page load, but in 'Timeline' section appear other error as below:

• in log:

2009-11-24 14:04:07,858 Trac[main] ERROR: argument to += must be iterable

• in project's page

Traceback (most recent call last):

File "/usr/lib/python2.3/site-packages/trac/web/main.py", line 387, in dispatch_request

dispatcher.dispatch(req)

File "/usr/lib/python2.3/site-packages/trac/web/main.py", line 237, in dispatch

resp = chosen_handler.process_request(req)

File "/usr/lib/python2.3/site-packages/trac/Timeline.py", line 117, in process_request

available_filters += event_provider.get_timeline_filters(req)

TypeError: argument to += must be iterable

Any idea?

[ffidelis@…]

second error

[anonymous]

Did you change lines 113 and 117 of HudsonTracPlugin.py too? They should read

        if req.perm.has_permission('BUILD_VIEW'):

and

        if 'build' not in filters or not req.perm.has_permission('BUILD_VIEW'):

respectively.

There has been no further feedback from submitter. So closing this, as I believe it has been fixed.
