2012-04-01	Merge remote-tracking branch 'brson/mainthread'	Brian Anderson	-5/+18
	Conflicts: src/rt/rust_sched_loop.cpp src/rt/rust_shape.cpp src/rt/rust_task.cpp
2012-03-31	rt: Fix whitespace	Brian Anderson	-1/+2

2012-03-31	rt: Introduce rust_sched_reaper	Brian Anderson	-5/+18
	This just moves the responsibility for joining with scheduler threads off to a worker thread. This will be needed when we allow tasks to be scheduled on the main thread.
2012-03-28	Tidy up multiple declarations and STDC_FOO_MACROS guards in headers.	Graydon Hoare	-5/+0

2012-03-28	Fix some gcc-4.4-isms, should build now on 4.1+.	Graydon Hoare	-1/+2

2012-03-18	rt: Remove lock_held_by_current_thread	Brian Anderson	-4/+0

2012-03-15	rt: Remove the kernel task table	Brian Anderson	-45/+5

2012-03-15	rt: Look up ports through a single port table	Brian Anderson	-0/+41
	Instead of a two-level lookup, just use one big table
2012-03-01	rt: Remove rust_kernel::live_tasks. Unused	Brian Anderson	-3/+2

2012-02-27	rt: Change the way the kernel exits to avoid pthread leaks	Brian Anderson	-17/+27
	This makes the kernel join every scheduler thread before exiting in order to ensure that all threads are completely terminated before the process exits. On my machine, for 32-bit targets, this was causing regular valgrind errors.
2012-02-09	rt: Make rust_task::ref_count private	Brian Anderson	-0/+1

2012-02-09	rt: Remove rust_task_user struct	Brian Anderson	-4/+4

2012-02-09	fix build on freebsd	Jyun-Yan You	-0/+5

2012-02-08	rt: Export a scheduler API	Brian Anderson	-2/+3

2012-02-08	rt: Hold schedulers in a map	Brian Anderson	-7/+52

2012-02-08	rt: Change the lifecycle of tasks and schedulers for various reasons	Brian Anderson	-5/+0
	This is in preparation for giving schedulers their own life cycle separate from the kernel. Tasks must be deleted before their scheduler thread, so we can't let the scheduler exit before all its tasks have been cleaned up. In this scheme, the scheduler will unregister tasks with the kernel when they are reaped, then drop their ref on the task (there may still be others). When the task ref count hits zero, the task will request to be unregistered from the scheduler, which is responsible for deleting the task. Instead of having the kernel tell the scheduler to exit, let the scheduler decide when to exit. For now it will exit when all of its tasks are unregistered.
2012-02-08	rt: Start schedulers immediately upon creation	Brian Anderson	-8/+6

2012-02-08	rt: Refactor the rust_kernel interface a bit	Brian Anderson	-18/+26

2012-02-08	rt: Introduce scheduler ids	Brian Anderson	-1/+1

2012-02-08	rt: Delete schedulers immediately upon release	Brian Anderson	-4/+1
	This will be needed once we support dynamically changing schedulers.
2012-02-08	rt: Change the scheme used for terminating the kernel	Brian Anderson	-5/+25
	Instead of joining on the scheduler threads, instead keep a count of active schedulers. When there are no more schedulers raise a signal for the main thread to continue. This will be required once schedulers can be added and removed from the running kernel.
2012-02-04	rt: Expand rust_kernel::live_tasks to a uintptr_t	Brian Anderson	-2/+2

2012-02-04	rt: Stop using atomic ops on rust_kernel::live_tasks	Brian Anderson	-2/+4
	These ops are all done within spitting distance of a suitable lock, so just protect it with the lock.
2012-02-03	rt: Add sanity checks when we hit the max task/port id	Brian Anderson	-0/+1

2012-02-03	rt: Clean up the way the kernel tracks tasks	Brian Anderson	-17/+28

2012-02-03	rt: Do all task creation through a scheduler	Brian Anderson	-11/+5

2012-02-03	rt: Extract rust_scheduler from rust_task_thread	Brian Anderson	-86/+16

2012-02-03	rt: Rename rust_scheduler to rust_task_thread	Brian Anderson	-13/+13

2012-02-02	rt: Only wake up all schedulers when no tasks are left	Brian Anderson	-4/+2
	At the moment there's not really any reason to be raising this signal, since they schedulers wake up periodically anyway, but once we remove the timer this will be how the schedulers know to exit.
2012-02-02	rt: Do all signalling while holding a lock	Brian Anderson	-1/+3
	This will matter once the scheduler is changed to not wake up on a timer
2012-02-01	rt: Remove calls to signal the kernel lock	Brian Anderson	-3/+0
	Nobody ever waits for it
2012-01-29	rt: Make the initial segment of the main task's stack 1MB	Brian Anderson	-2/+8
	This is a trick to fool microbenchmarks. Closes #1681
2012-01-12	libcore: Add sys::set_exit_status	Brian Anderson	-1/+11
	Sets the process exit code
2012-01-06	fix how we walk functions to match new closure fmt	Niko Matsakis	-1/+1

2011-12-20	rt: Lock before using the random number generator	Brian Anderson	-5/+3
	Seeing crashes here trying to stress test concurrent tasks
2011-09-20	rt: Rename rand() to isaac_rand() since the former prevents lots of standard ↵	Patrick Walton	-1/+1
	headers from being included
2011-09-11	Use a unique exit status when the runtime fails normally	Brian Anderson	-1/+1
	Check for it in run-fail tests
2011-08-24	Return an error code after fail under win32	Brian Anderson	-1/+1

2011-08-17	Making more of the rust_task structure directly accessible from Rust.	Eric Holk	-3/+3

2011-08-15	Abort abruptly on failure on windows	Brian Anderson	-0/+6
	Trying to shutdown cleanly results in wierd failures
2011-08-15	Reducing the chances for race conditions in join.	Eric Holk	-1/+11

2011-08-15	Properly ref counting to fix valgrind issues on linux.	Eric Holk	-0/+1

2011-08-10	rt: Shutdown gracefully on failure	Brian Anderson	-0/+8
	When the kernel fails, kill all tasks and wait for the schedulers to stop instead of just exiting. I'm sure there are tons of lurking issues here but this is enough to fail without leaking (at least in the absence of cleanups).
2011-08-08	Introduced task handles.	unknown	-2/+24
	This is the new way to refer to tasks in rust-land. Currently all they do is serve as a key to look up the old rust_task structure. Ideally they won't be ref counted, but baby steps.
2011-07-29	Minimize scheduler locking on task creation	Brian Anderson	-1/+0
	This takes my CPU utilization on task-perf-spawnalot from 35% to 55%
2011-07-29	Lock the new task's scheduler when creating a task	Brian Anderson	-1/+3
	Previously we were locking the spawning task's scheduler. I couldn't see that that was protecting anything. The newborn_task list in the new task's scheduler though was unprotected from concurrent access. So now we're locking the new task's scheduler.
2011-07-29	Removing proxies and message queues.	Eric Holk	-136/+3

2011-07-28	Do all runtime calls to getenv at initialization	Brian Anderson	-1/+4
	getenv is not threadsafe and (maybe as a result) it's randomly crashing with CFLAGS=-g and RUST_THREADS=32. Calls from rust code are still on their own.
2011-07-28	Updating to work on Windows.	Eric Holk	-2/+4

2011-07-28	Resurrecting some of the logging in rust_chan.cpp	Eric Holk	-18/+14
