4b356097c2 Change the locking rules around channel disassociation again 
This prevents port's destructor from accessing a deleted channel

5c0fd045ce Fiddle with the locking around channel disassociation 
This still looks a bit sketchy to me (why isn't there locking in
port::destroy?) but this manages to get rid of a problem with channels
accessing their task after it's NULL.

0fcd72c932 When using the allow leaks hack don't even print a warning about the leak 
This is only used for the test runner and in that case it just makes the test
output confusing

4ef1ec580a Do all runtime calls to getenv at initialization 
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.

75985ab75e Remove color-related code from rust_log 
This is all dead. If someone decides they want color it will be easy to redo.

a5fe66e706 Adding upcalls to to ref() and deref() tasks. This is the first step towards atomic reference counting of tasks. 2011-07-28 10:47:28 -07:00

5302cde188 Made task threads wait instead of sleep, so they can be woken up. This appears to give us much better parallel performance. 
Also, commented out one more unsafe log and updated rust_kernel.cpp to compile under g++

e697a52359 Adding a function to stdlib to set the min stack size, for programs 
that absolutely will not succeed with a large default stack. This
should be removed once we have stack grown working.

Also updated word-count to succeed under the new test framework.

62bc6b5113 Per-thread scheduling. Closes #682. 
Tasks are spawned on a random thread. Currently they stay there, but
we should add task migration and load balancing in the future. This
should drammatically improve our task performance benchmarks.

the returned pointer.

8878b128ba More work on word-count. 
Updated the MapReduce protocol so that it's correct more often. It's
still not perfect, but the bugs repro less often now.

Also found a race condition in channel sending. The problem is that
send and receive both need to refer to the _unread field in
circular_buffer. For now I just grabbed the port lock to send. We can
probably get around this by using atomics instead.

d79afd7916 Improving move semantics for channel operations.

3ae4dcd41e Lots of work on memory tracking and channels. 
We're trying to get closer to doing correct move semantics for channel
operations. This involves a lot of cleanup (such as removing the
unused sched parameter from rust_vec constructor) and making
circular_buffer kernel_owned.

Added tagging for memory allocations. This means we give a string tag
to everything we allocate. If we leak something and TRACK_ALLOCATIONS
is enabled, then it's much easier now to tell exactly what is leaking.

a467e8e4e6 Add a huge hack to allow the test runner to continue if a single task leaks 
This is just until unwinding works. Adds a flag to the runtime to turn
the memory leak checks on task destruction into warnings instead of fatal
errors. I am so sorry.

crashing or leaking.

01a52d728c Add an unsupervise builtin and function to std::task 
Calling task::unsupervise de-parents the current task, with the result
that failures do not propogate up the task tree.

4738cf83b0 Move the responsibility for process failure from tasks to the scheduler 
When the root task fails the process fails. Failures on other tasks propagate
up the task tree. Failures on non-root tasks without parents just
(theoretically) unwind and disappear.
