Re: [xwiki-devs] [Proposal] Members of subwiki migration

Hi Guillaume, I am definitely -1 to systematically replace XWikiAllGroup by XWikiMemberGroup in any subwiki: 1) because I do not see the meaning of XWikiMemberGroup in the myxwiki.orguse case. 2) because XWikiAllGroup is an habits for many existing user 3) because existing application/extension/scripts may attribute rights to XWikiAllGroup 4) because this could cause confusion if some right are attributed to XWikiAllGroup and others to XWikiMemberGroup, by a mixup of old and new habits. Since we definitely want to use implicit XWikiAllGroup, I do understand that you need a solution for workspace that may be joined by global

The below proposal should allow you to do so without migrating existing installation. It apply only to subwikis. After thinking about the different possibilities, my best bet to a smooth migration is to keep XWikiAllGroup for its previous meaning: "All authenticated users having access to this wiki" (unless implicit, which restrict it currently to "All Local Users"). Keeping the meaning and potential usage of the group is the key IMO. To support selected global users to enter the implicit XWikiAllGroup, I simply suggest to add implicitly a group as a member of XWikiAllGroup. It could be called XWikiGlobalMemberGroup to be more explicit, and always

member of the implicit XWikiAllGroup when xwiki.authentication.group.allgroupimplicit=2. Then: A) when xwiki.authentication.group.allgroupimplicit=0, and XWikiAllGroup (not implicit) does not have a member XWikiGlobalMemberGroup. Do not do

migration, and keep the current join behavior, using exclusively XWikiAllGroup for both local and global users. B) when xwiki.authentication.group.allgroupimplicit=1, keep the existing behavior, obviously prevent any global user to join, do not provide

user scope in wiki creation, and warn on the wiki setting if the user

is incompatible with the current implicit setting. C) when xwiki.authentication.group.allgroupimplicit=2, check at startup that a XWikiGlobalMemberGroup exists, else create it and migrate any

users in XWikiAllGroup to XWikiGlobalMemberGroup. D) when xwiki.authentication.group.allgroupimplicit=2, or when xwiki.authentication.group.allgroupimplicit=0 and XWikiAllGroup contains XWikiGlobalMemberGroup, use the new behavior, allowing creation of all

scopes, removing any warnings, joining global users to the XWikiGlobalMemberGroup (and local users to the XWikiAllGroups if not implicit). The net benefit of the above proposal is to keep actual habits and

use cases untouched. Moreover, the security is ensured to be kept as it

with no risk of side effect, which is priority. WDTH ? Obviously, my +1 for the above proposal.
