Using 1.8.3 recipe with OpenERP trunk, I get the following error message when starting OpenERP :

Hi,

I've the same problem, The bug appear when we try to launch the server in a multi worker mode ( --workers=2). I've fixed the bug on my machine. A MP will follow.

Regards,

lmi

Thanks for the report, Maxime.
Thanks for the fix, Laurent.

[Georges Racinet (gracinet)]

Actually, Laurent's fix is not enough anymore on odoo.
It allows to find the openerp-gevent script that ships with odoo, but that script can't run in the buildout context, for two reasons:

* it has an hardcoded shebang on /usr/bin/env python
* it can't have the sys.path initialization that is the core principle of zc.buildout.

Basically, that gevent-openerp should have been the one generated by setup.py and should not be versioned with the sources. Besides, the launcher should not make any assumptions on its name or path. I'll try and explain that to the odoo team.

In any case, we need to have the recipe generate the proper script (that's easy, and the right thing to do for split running) and to register it in some way so that the --workers spawner will call it.

Maybe I should file a new ticket on the recipe for that.

[Georges Racinet (gracinet)]

Forgot to add that current exception is an ImportError on gevent.monkey.
And that's because the gevent script has none of the recipe's paths

This may not be so visible with buildouts that aren't isolated by a virtualenv, on hosts having global gevent and gevent-psycopg2 packages.

[Georges Racinet (gracinet)]

Fixed at the end of may by implementing the plan as explained above.
