2013-08-20auto merge of #8566 : toddaaro/rust/idle-opt+cleaning, r=catamorphism,brsonbors-1/+1
Instead of a furious storm of idle callbacks we just have one. This is a major performance gain - around 40% on my machine for the ping pong bench. Also in this PR is a cleanup commit for the scheduler code. Was previously up as a separate PR, but bors load + imminent merge hell led me to roll them together. Was #8549.

updated, a minor amount of support type restructing has happened, methods have been reordered, and some duplicate code has been purged.

2013-08-05Updated std::Option, std::Either and std::ResultMarvin Löbel-2/+2
- Made naming schemes consistent between Option, Result and Either - Changed Options Add implementation to work like the maybe monad (return None if any of the inputs is None) - Removed duplicate Option::get and renamed all related functions to use the term `unwrap` instead
2013-08-05std::rt: Use magic to make TLS work from annihilated boxes. #8302Brian Anderson-0/+13

rustc needs *even more* megabytes when run without optimizations
2013-08-03std::rt: Run local storage cleanup and the box annihilator inside the try/catchBrian Anderson-27/+22
And before collect_failure. These are both running user dtors and need to be handled in the task try/catch block and before the final task cleanup code.
2013-08-02auto merge of #8195 : bblum/rust/task-cleanup, r=brsonbors-2/+7
In the first commit it is obvious why some of the barriers can be changed to ```Relaxed```, but it is not as obvious for the once I changed in ```kill.rs```. The rationale for those is documented as part of the documenting commit. Also the last commit is a temporary hack to prevent kill signals from being received in taskgroup cleanup code, which could be fixed in a more principled way once the old runtime is gone.
2013-08-01modified local to include an implementation for try_unsafe_borrow::<Task> so ↵toddaaro-0/+1
that the log methods will work

scheduler functions slightly
2013-08-01minor tweaks - unboxed the coroutine so that it is no longer a ~ pointer ↵toddaaro-6/+6
inside the task struct, and also added an assert to verify that send is never called inside scheduler context as it is undefined (BROKEN) if that happens
2013-08-01A major refactoring that changes the way the runtime uses TLS. In thetoddaaro-54/+161
old design the TLS held the scheduler struct, and the scheduler struct held the active task. This posed all sorts of weird problems due to how we wanted to use the contents of TLS. The cleaner approach is to leave the active task in TLS and have the task hold the scheduler. To make this work out the scheduler has to run inside a regular task, and then once that is the case the context switching code is massively simplified, as instead of three possible paths there is only one. The logical flow is also easier to follow, as the scheduler struct acts somewhat like a "token" indicating what is active. These changes also necessitated changing a large number of runtime tests, and rewriting most of the runtime testing helpers. Polish level is "low", as I will very soon start on more scheduler changes that will require wiping the polish off. That being said there should be sufficient comments around anything complex to make this entirely respectable as a standalone commit.
2013-08-01Temporary workaround to prevent taskgroup cleanup code from failing without ↵Ben Blum-2/+7

2013-07-30std::rt: Use 2MB stacksBrian Anderson-1/+1
Seems to be around the minimum needed by rustc without split stacks
2013-07-26Consolidate raw representations of rust valuesAlex Crichton-1/+1
This moves the raw struct layout of closures, vectors, boxes, and strings into a new `unstable::raw` module. This is meant to be a centralized location to find information for the layout of these values. As safe method, `repr`, is provided to convert a rust value to its raw representation. Unsafe methods to convert back are not provided because they are rarely used and too numerous to write an implementation for each (not much of a common pattern).

2013-07-14Make TLS keys actually take up spaceAlex Crichton-2/+2
If the TLS key is 0-sized, then the linux linker is apparently smart enough to put everything at the same pointer. OSX on the other hand, will reserve some space for all of them. To get around this, the TLS key now actuall consumes space to ensure that it gets a unique pointer
2013-07-14Purge the last remnants of the old TLS apiAlex Crichton-8/+6
Closes #3273
2013-07-11auto merge of #7677 : alexcrichton/rust/tls-gc, r=pcwaltonbors-6/+6
cc #6004 and #3273 This is a rewrite of TLS to get towards not requiring `@` when using task local storage. Most of the rewrite is straightforward, although there are two caveats: 1. Changing `local_set` to not require `@` is blocked on #7673 2. The code in `local_pop` is some of the most unsafe code I've written. A second set of eyes should definitely scrutinize it... The public-facing interface currently hasn't changed, although it will have to change because `local_data::get` cannot return `Option<T>`, nor can it return `Option<&T>` (the lifetime isn't known). This will have to be changed to be given a closure which yield `&T` (or as an Option). I didn't do this part of the api rewrite in this pull request as I figured that it could wait until when `@` is fully removed. This also doesn't deal with the issue of using something other than functions as keys, but I'm looking into using static slices (as mentioned in the issues).
