2755c342e6 Added extra comments to explain the ACL_USER_BASE flags usage, as well as fix an issue with get_role_access. 
The bug caused roles rights to not be propagated if a push on the stack happened. The newly finished neighbour
was never reevaluated.

565c6c5a1f Cascading updates for roles_mappings are now fully functional. 
Renaming a user via RENAME USER command causes either the user columns
to update, or the role columns.

9506a07159 Added debug info to rebuild_roles_mappings 
Also fixed a bug regarding the HASH iteration. It previously got
the stop condition from a different hashtable and this caused errors
when the hash sizes were different.

de472770d3 Removed no longer needed hash_walk_action. The function was used to delete 
no longer valid entries in the roles_mappings HASH. This job will be delegated
to handle_grant_* functions
 2013-10-17 15:09:14 -07:00

6988e6c56a The acl_roles_mappings in-memory structure holds the following invariant: 
It will only hold _valid_ entries for as long as it held in memory. Any change
regarding acl_users or acl_roles in memory should update the structure
immediately. This is why the rebuild_roles_mappings no longer removes invalid
entries.

In order to keep things consistent with the existing code, the following jobs
are assigned to each function:

The role of rebuild_roles_mappings is to recreate the links between users and
roles. Any other updates are to be done in the functions:

handle_grant_*

This change prepares the code for the next step, which is cascading updates.

5acc057879 Roles mappings are now being kept consistent when acl_users gets modified. 
No cascading changes take place during a user rename. This needs to be
addressed.
