#473188: missing get_page_data when patching bare db-api request for web compatibility

benefit from the orm for clearer code

close #472361: omit password and bytes attributes in allowed mass-mailing keys by fixing default implementation for allowed_massmail_keys() in the Emailable pluggable mixin (cw.common.mixins). Added test (in entities.test though), also fix CWUserTC classes conflicts in the test module.

close #474415 by using 'is' instead of comparison which explicitly fails on entity classes

when instance is started normally (eg not in debug mode), check versions before daemonization

doc

close #511810: bad rql generated when looking for vocabulary for a relation on an entity which doesn't exist (yet) technical details: * add a graph of linked variables in the RRQLExpression instance * modify rql rewriter to remove relations where an unexistant variable and or a variable linked to an unexistant variable is used. * activate this feature in Entity.unrelated_rql if the entity doesn't exists yet

typo

consider U when computing main variables

fix cut and paste

do not fail if anon user == manager, simply emit warning that it should not be done in production. close #469395

oops, junk
