Hello.
This error took from us some time to solve, but i think it is important.
When you define the first addons base in a folder called addons and in the same directory that your other addons branches i mean:
/working/directory/trunk/addons
/working/directory/trunk/addons-other
/working/directory/trunk/web
/working/directory/trunk/server
And you start server with addons path:
/working/directory/trunk/addons,/working/directory/trunk/addons-other,/working/directory/trunk/web/addons
When the second addons is taken in account the algorithm already in server brakes telling you can not load __opener__.py server that dont existe, the traceback looks like this:

We must use "name" (modified name that is realle used to find __openerp__.py file) and not "basename" (original name first used to compare if it is base module or not).
2.- The second part is "Why the file is bad named?" if all folders worked __exactly__ in this naming convention on 6.1?:
The reason is the commit 4420 done for Stephan:
The diff of this revno 4420 :

For some reason, he replace basename = name with a new return, imho it was not necesary, but bte, just changing veriable it works very well.
3rd. Part: Bad Algorithm:.
The algorithm to find the path that is in misc.py file IMHO is incorrect, because compare "String of path" and not "Path itself" to decide if it is or not base-addons.
You can see:
line ~139 openerp/tools/misc.py:
for root in adps + [rtp]:
if name.startswith(root):
base = root.rstrip(os.sep)
name = name[len(base) + 1:]
break
What is wrong, is that we are using 'startswith' instead a path tool to compare and strip folders name, the in case you use a second folder with a second list of addons it is striping incorrectly, and giving an incorrect message (corrected in point [2])
Printing root, adps and
[u'/home/nhomar/instancias/7.0/addons', u'/home/nhomar/instancias/7.0/addons-vauxoo', u'/home/nhomar/instancias/7.0/web/addons', u'/home/nhomar/instancias/7.0/test_pycon', u'/home/nhomar/instancias/7.0/openerp-venezuela-localization', '/home/nhomar/instancias/7.0/server/openerp/addons']
/home/nhomar/instancias/7.0/addons
/home/nhomar/instancias/7.0/server/openerp
In my case as you can see:
When you make name.startswith(root):
/home/nhomar/instancias/7.0/addons
/home/nhomar/instancias/7.0/addons-vauxoo
This case will pass and:
name = name[len(base) + 1:]
will become:
vauxoo/user_story/__openerp__.py
what is incorrect, because this folder doesn't exists.
Solution:
I will make an MP, solving the problem with 'os' library, soon in touch |
