Subject: [PATCH] Performance & Concurrency Improvements to Permissions
|
|
|
|
Modifying of permissions was only half protected, enabling concurrency
|
|
issues to occur if permissions were modified async.
|
|
|
|
While no plugin really should be doing that, modifying operations
|
|
are not heavily called, so they are safe to add synchronization to.
|
|
|
|
Now, all modification API's will be synchronized ensuring safety.
|
|
|
|
Additionally, hasPermission was victim to a common java newbie mistake
|
|
of calling if (containsKey(k)) return get(k), resulting in 2 map lookups.
|
|
|
|
Optimized it to simply be a single get call cutting permission map
|
|
lookups in half.
