This makes it easier for downstream projects (forks) to replace the version fetching system with their own. It is as simple as implementing an interface and overriding the default implementation of org.bukkit.UnsafeValues#getVersionFetcher() It also makes it easier for us to organize things like the version history feature. Lastly I have updated the paper implementation to check against the site API rather than against jenkins.

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.
