Bertrand Delacretaz commented on SLING-11160:
---------------------------------------------
I agree with your comment on {{remove repository ACL}}, and I think this means
that the grammar will not simply reproduce all {{set ACL}} constructs as
{{remove ACL}} ones.
That will make the grammar a bit more complicated but I think that's fine, as
long as we add all the required test cases to make things clear. And also to
produce good documentation [on the Sling
website|https://sling.apache.org/documentation/bundles/repository-initialization.html#appendix-a-repoinit-syntax-parser-test-scenarios-1],
where the _Repoinit parser test scenarios_ section is generated from the test
cases.
I also agree with your view on {{remove *}}.

> Key: SLING-11160
> URL: https://issues.apache.org/jira/browse/SLING-11160
> Project: Sling
> Issue Type: Bug
> Components: Repoinit
> Reporter: Angela Schreiber
> Assignee: Angela Schreiber
> Priority: Major
> Attachments: SLING-11160-initial-draft.patch

> Time Spent: 10m
> Remaining Estimate: 0h

> With SLING-9090 support for using _REMOVE *_ for all entries at a given path
> or for a given principal has been implemented.
> However as indicated in the same issue the intended usage of _REMOVE
> some-thing-specific_ is not clear.
> What is therefore missing with repo-init is the ability to remove a single
> access control entry that matches
> - prinicipal
> - privileges
> - allow-status
> - single value restriction
> - mv restrictions.
> As far as I can see the biggest issue is the fact that REMOVE vs ALLOW/DENY
> are mutually exclusive as the other params listed above can be extracted from
> a given AclLine in combination with the set-ACL statement.
> This could be fixed by adjusting the following parser method
> {code}
> AclLine privilegesLineOperation() :
> {}
> {
> (
> <REMOVE> { return new AclLine(AclLine.Action.REMOVE); }
> | ( <ALLOW> { return new AclLine(AclLine.Action.ALLOW); } )
> | ( <DENY> { return new AclLine(AclLine.Action.DENY); } )
> )
> }
> {code}
> such that
> - REMOVE is optional, followed by
> - ALLOW or DENY
> The {{AclLine}} would then need to be slightly adjusted such that REMOVE can
> be combined with either ALLOW or DENY.
> Otherwise, I don't see how
> {{AccessControlList.removeAccessControlEntry(AccessControlEntry)}} could be
> implemented in org.apache.sling.jcr.repoinit for a single ACE.
> Or maybe the intention was something different in the first place?
> [~bdelacretaz], I would appreciate if you had time to comment on this.
