792068d871 rt: Remove unblock call from rust_task::yield 2011-11-18 14:45:48 -08:00
Brian Anderson
3a6320f71b intrinsics: Eliminate recv intrinsic 
This intrinsic existed just to get ahold of the return pointer. I replaced it
with a call_with_retptr intrinsic that grabs the return pointer and passes it
to another Rust function, thereby eliminating the need to call C functions on
the Rust stack.

e4f980810b rt: Simplify channel-port association 
It turns out that there's only ever a single channel per port these days,
and it always has the same lifetime as the port, so we don't need a list or a
complex association protocol.

02d7a1e781 move sys fns into c-stack-cdecl and get_type_desc() into rusti 
there is one test failure, stdtest/sys.rs, which inexplicably
(thus far) fails to compile because it invokes
sys::rustrt::last_os_error() instead of invoking
sys::last_os_error().  If stdtest/sys.rs is updated to invoke
the wrapper, it passes.  Still tracing the source of this error.

25ae3d655c Rewrite spawn yet again 
The motivation here is that the bottom of each stack needs to contain a C++
try/catch block so that we can unwind. This is already the case for main, but
not spawned tasks.

c9c5ee252a Implement non-internal ivecs 
Vectors are now similar to our old, pre-internal vectors, except that
they are uniquely owned, not refcounted.

Their name should probably change too, then. I've renamed them to vec
in the runtime, will do so throughout the compiler later.

44bef5f2cb Introduced task handles. 
This is the new way to refer to tasks in rust-land. Currently all they

they won't be ref counted, but baby steps.

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.

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

errors. I am so sorry.

4739953b84 Fixed two races. 
The first is that the memory_region destructor would complain there is
still an outstanding allocation. This is because circular_buffer from
rust_chan wasn't refing its task, so the task was being destructed too
soon.

The second was where the program could deadlock while joining a
task. The target task would die in the time between checking whether
the task should block and then actually blocking. The fix is to use
the target task's lock.

880be6a940 Overhaul logging system in runtime 
See https://github.com/graydon/rust/wiki/Logging-vision

The runtime logging categories are now treated in the same way as
modules in compiled code. Each domain now has a log_lvl that can be
used to restrict the logging from that domain (will be used to allow
logging to be restricted to a single domain).

Features dropped (can be brought back to life if there is interest):
  - Logger indentation
  - Multiple categories per log statement
  - I possibly broke some of the color code -- it confuses me
