d392556160 std: Fix perf of local allocations in newsched 
Mostly optimizing TLS accesses to bring local heap allocation performance
closer to that of oldsched. It's not completely at parity but removing the
branches involved in supporting oldsched and optimizing pthread_get/setspecific
to instead use our dedicated TCB slot will probably make up for it.

af2e03998d Enabled workstealing in the scheduler. Previously we had one global work queue shared by each scheduler. Now there is a separate work queue for each scheduler, and work is "stolen" from other queues when it is exhausted locally. 2013-08-08 14:13:41 -07:00

0ac7a219f0 Updated std::Option, std::Either and std::Result 
- 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

a5f55b3ead minor tweaks - unboxed the coroutine so that it is no longer a ~ pointer 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 2013-08-01 15:17:19 -07:00

f7eed22387 A major refactoring that changes the way the runtime uses TLS. In the 
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.

78cde5b9fb std: Change Times trait to use do instead of for 
Change the former repetition::

    for 5.times { }

to::

    do 5.times { }

.times() cannot be broken with `break` or `return` anymore; for those
cases, use a numerical range loop instead.

8b7e241e02 auto merge of #8139 : brson/rust/rm-old-task-apis, r=pcwalton 
This removes a bunch of options from the task builder interface that are irrelevant to the new scheduler and were generally unused anyway. It also bumps the stack size of new scheduler tasks so that there's enough room to run rustc and changes the interface to `Thread` to not implicitly join threads on destruction, but instead require an explicit, and mandatory, call to `join`.
