Merge lp:~openerp-community/openerp-web/trunk-smart-load-module into lp:openerp-web

[Simone Orsi]

improved load of modules by looking only for web addons** and by not failing silently when no 'static' folder is found.

** in general all the web module should respect the declaration of web=True in the manifest but since there seems to be a lof of missing declaration I check as a fallback for 'web0 in 'depends'.

[Xavier (Open ERP) (xmo-deactivatedaccount)]

Sadly, the `web` key is a flag for 6.0 modules, its semantics are not defined in relations to openerp-web.

so chekcing only for static resource declared should be enough for handling this, isn it?

[Simone Orsi (simone-orsi)]

the problem here is that w/ the current implementation you have to define a static folder even if you don't need it at all. if you define a controller into your module but yoou don't put an *empty* static folder in it your module don't get loaded at all and silently. I think this is a bad behaviour.

[Antony Lesuisse (OpenERP) (al-openerp)]

I agree that the heuristic based on the /static/ dir is not be the best solution but, as we plan to change the module loading process in the server, i propose not to change this mechanism at the moment.

ok, I agree, but still I think you should log this at least in debug mode.
Moreover: any place where to see/read/test new module loading process?

load module only if IS web one and don't fail silently if no 'static' folder is provided
