Review via email: mp+222760@code.launchpad.net

Description of the change

replace product_gtin with chricar_product_gtin (from c2c-rd-addons), which works (whereas the existing module was not installable).

I ported the history of changes of that addon using bazaar-extractor, and Alexis de Lattre did the actual porting to V7 + OCA coding standards

Alexandre, could you replay my commit revno 249 in the branch lp:~akretion-team/openerp-product-attributes/70-update-and-fix-product-gtin ; it's a small code simplification.

Alexis, why don't you propose to odoo to make a method called check_ean_length in the same way as check_ean and use it on PoS, so that we can extend easily PoS codebar recognition via server modules (not JS)?

Regards.
