Alex Deparvu commented on OAK-8234:
-----------------------------------
bq. Alex Deparvu, while the intended change makes a lot of sense to me, i don't
particularly like the delegatee approach with yet another redirection. in
particular since it creates a lot of changes to the PermissionProviderImpl that
might result in subtle regressions. Is there a reason for not making the
distinction between administrative subjects and regular subjects right in the
AuthorizationConfigurationImpl? that would place that fundamental difference
between set of principals that are subjected to permission evaluation vs those
that are not prominently in the flow. also for administrative principals the
whole Mount handling is IMO redundant and which is not taken into account in
the patch as far as i saw. wdyt?
Interesting suggestion, I had not considered this but it makes more sense to
inject the admin provider directly in the {{AuthorizationConfigurationImpl}}.
I'll update the patch.

> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core, security
> Reporter: Alex Deparvu
> Assignee: Alex Deparvu
> Priority: Major
>
> There was already a lot of work done here to improve efficiency of admin
> sessions, but we can still do better by simply not creating many of the
> objects needed as parameters for the {{CompiledPermissions}} which will be
> ignored anyway in the case of admin sessions.
> Ex: There are a lot of immutable trees (created via
> {{PermissionUtil.getReadOnlyTree(tree, immutableRoot)}}) that are not used
> for the evaluation.
> Thanks to [~mreutegg] for spotting this one!
