Enabling plugin causes SystemError: Parent module 'repository_hook_system' not loaded

[anonymous]

I just installed this plugin. Immediately after enabling the plugin trac dies with the following traceback:

Traceback (most recent call last):
  File "/usr/lib/python2.5/site-packages/trac/web/api.py", line 367, in send_error
    'text/html')

How is this plugin being installed? DL source + python setup.py install or direct DL of egg?

[anonymous]

easy_install from svn source.

I tried variations on the TracPlugins​http://trac.edgewall.org/wiki/TracPlugins installation page

I just now completely uninstalled it then reinstalled it by dl zipped source and building it with "python setup.py bdist_egg" then copying the egg into my plugins dir under my trac instance. I have also done a variation on that "python setup.py install"

still the final system error is the same.

[Jeff Hammel]

working on reproduction; so far no luck

[Jeff Hammel]

Reproduced.

Reproduction steps:

(using ​virtualenv)

• from the command line:

virtualenv trac
cd trac
. bin/activate
mkdir src
cd src 
svn co http://trac-hacks.org/svn/traclegosscript/anyrelease/ TracLegos
cd TracLegos
python setup.py develop
cd example/oss
python setup.py develop
cd -
paster serve --reload development.ini

(Note: this is boilerplate)

• Go to ​http://127.0.0.1:8081

• Click Create Project

• Enter name and URL: foo, foo

• Click next and then create project

• restart paster (kill and then run above command again) this is necessary because the installed plugins are not loaded into python; need to work around this

trac-admin trac/src/TracLegos/projects/foo upgrade

• refresh page

• click register tab

• create an account

trac-admin src/TracLegos/projects/foo permission add <username> TRAC_ADMIN

• reload page, click admin tab

• in src/, svn co http://trac-hacks.org/svn/repositoryhooksystemplugin/0.11/ RepositoryHookSystem

• cd RepositoryHookSystem/

• python setup.py install

• restart paster/trac (again)

• click on plugins

• enable the RepositoryHookSystem plugin

(sorry for the verbosity, but wanted to give the whole procedure for posterity)

i notice that package data isn't included properly; will try to fix that and see if it helps

[Jeff Hammel]

(In [5108]) move import of pkg_resources to top of file; refs #4361

Replying to k0s:

(In [5108]) move import of pkg_resources to top of file; refs #4361

well, now i'm even more confused. this seems to fix one issue but makes the other components disappear. will redo reproduction steps and hopefully see what's going on

[Jeff Hammel]

i also still don't understand the root cause of this error at all; my only current suspicion is my bad handling of __init__.py, but its purely a far-fetched guess

[Jeff Hammel]

think i fixed; trying to reproduce with above steps to make sure; still unsure what the issue was/is

[Jeff Hammel]

should be fixed now; again, not really sure where the error ultimately was

[anonymous]

confirmed. The plugin now works.
