Wesley Wolfe dcd01bf0c0 Rewrite scheduler. Fixes BUKKIT-1831, and BUKKIT-845
The new scheduler uses a non-blocking methodology. Combining volatile
references to make a linked reference chain, with the atomic reference
handling the tail, tasks are queued without waiting for locks. The main
thread will no longer limit the length of time spend for scheduled tasks,
but no task will run twice in the same tick. Scheduling a new task inside of
a synchronous task will always run the new task during the same tick,
assuming there is no supplied delay > 0.

Asynchronous tasks are now run using a thread pool. Any thread-local
implemenation should now account for threads being reused between
executions.

Race conditions were carefully examined and the order of logic is now very
important. Each task is placed in a secondary collection before removal from
primary collections. Thus, by reading tasks from the collections in the same
order they travel, it retains state-safety. This does make modifications
less responsive in some situations, as the task may be transitioning before
the modifier accesses it. This cost outweighs the requirement to synchronize
on the scheduler; previously any conflict would be first-come-first-serve,
with the main thread backing out arbitrarily.

CraftBukkit

A Bukkit (Minecraft Server API) implementation

Website: http://bukkit.org
Bugs/Suggestions: http://leaky.bukkit.org

Compilation

We use maven to handle our dependencies.

  • Install Maven 3
  • Check out and install Bukkit
    • Note: this is not needed as the repository we use has Bukkit too, but you might have a newer one (with your own changes :D)
  • Check out this repo and: mvn clean package

Coding and Pull Request Conventions

  • We generally follow the Sun/Oracle coding standards.
  • No tabs; use 4 spaces instead.
  • No trailing whitespaces.
  • No CRLF line endings, LF only, put your gits 'core.autocrlf' on 'true'.
  • No 80 column limit or 'weird' midstatement newlines.
  • The number of commits in a pull request should be kept to a minimum (squish them into one most of the time - use common sense!).
  • No merges should be included in pull requests unless the pull request's purpose is a merge.
  • Pull requests should be tested (does it compile? AND does it work?) before submission.
  • Any major additions should have documentation ready and provided if applicable (this is usually the case).
  • Most pull requests should be accompanied by a corresponding Leaky ticket so we can associate commits with Leaky issues (this is primarily for changelog generation on dl.bukkit.org).
  • Try to follow test driven development where applicable.

If you make changes or add net.minecraft.server classes it is mandatory to:

  • Get the files from the mc-dev repo - make sure you have the last version!
  • Make a separate commit adding the new net.minecraft.server classes (commit message: "Added x for diff visibility" or so).
  • Then make further commits with your changes.
  • Mark your changes with:
    • 1 line; add a trailing: // CraftBukkit [- Optional reason]
    • 2+ lines; add
      • Before: // CraftBukkit start [- Optional comment]
      • After: // CraftBukkit end
  • Keep the diffs to a minimum (really important)

Tips to get your pull request accepted

Making sure you follow the above conventions is important, but just the beginning. Follow these tips to better the chances of your pull request being accepted and pulled.

  • Make sure you follow all of our conventions to the letter.
  • Make sure your code compiles under Java 5.
  • Provide proper JavaDocs where appropriate.
  • Provide proper accompanying documentation where appropriate.
  • Test your code.
  • Make sure to follow coding best practises.
  • Provide a test plugin binary and source for us to test your code with.
  • Your pull request should link to accompanying pull requests.
  • The description of your pull request should provide detailed information on the pull along with justification of the changes where applicable.
