green: Rip the bandaid off, introduce libgreen

2013-12-25T03:59:52+00:00

This extracts everything related to green scheduling from libstd and introduces a new libgreen crate. This mostly involves deleting most of std::rt and moving it to libgreen. Along with the movement of code, this commit rearchitects many functions in the scheduler in order to adapt to the fact that Local::take now *only* works on a Task, not a scheduler. This mostly just involved threading the current green task through in a few locations, but there were one or two spots where things got hairy. There are a few repercussions of this commit: * tube/rc have been removed (the runtime implementation of rc) * There is no longer a "single threaded" spawning mode for tasks. This is now encompassed by 1:1 scheduling + communication. Convenience methods have been introduced that are specific to libgreen to assist in the spawning of pools of schedulers.

Fallout of rewriting std::comm

libextra: Another round of de-`Cell`-ing.

2013-12-10T23:13:12+00:00

34 uses of `Cell` remain.

libstd: Remove all non-`proc` uses of `do` from libstd

Remove linked failure from the runtime

2013-11-25T05:21:12+00:00

The reasons for doing this are: * The model on which linked failure is based is inherently complex * The implementation is also very complex, and there are few remaining who fully understand the implementation * There are existing race conditions in the core context switching function of the scheduler, and possibly others. * It's unclear whether this model of linked failure maps well to a 1:1 threading model Linked failure is often a desired aspect of tasks, but we would like to take a much more conservative approach in re-implementing linked failure if at all.

libstd: Change all uses of `&fn(A)->B` over to `|A|->B` in libstd

libstd: Change all `~fn()`s to `proc`s in the standard library.

2013-11-19T02:27:30+00:00

This makes `Cell`s no longer necessary in most cases.

Remove unnecessary unwind messages

2013-11-01T18:58:25+00:00

Now that the type_id intrinsic is working across crates, all of these unnecessary messages can be removed to have the failure type for a task truly be ~Any and only ~Any

Prepared `std::sys` for removal, and made `begin_unwind` simpler

2013-10-30T20:19:18+00:00

- `begin_unwind` is now generic over any `T: Any + Send`. - Every value you fail with gets boxed as an `~Any`. - Because of implementation details, `&'static str` and `~str` are still handled specially behind the scenes. - Changed the big macro source string in libsyntax to a raw string literal, and enabled doc comments there.

Allow fail messages to be caught, and introduce the Any trait

2013-10-28T07:50:32+00:00

Some code cleanup, sorting of import blocks Removed std::unstable::UnsafeArc's use of Either Added run-fail tests for the new FailWithCause impls Changed future_result and try to return Result<(), ~Any>. - Internally, there is an enum of possible fail messages passend around. - In case of linked failure or a string message, the ~Any gets lazyly allocated in future_results recv method. - For that, future result now returns a wrapper around a Port. - Moved and renamed task::TaskResult into rt::task::UnwindResult and made it an internal enum. - Introduced a replacement typedef `type TaskResult = Result<(), ~Any>`.
