1347d04bb0 rt: Properly block tasks while waiting for port detach 2012-03-05 19:39:56 -08:00
Brian Anderson
4c4a2320eb rt: Make rust_port_detach less contentious 
It still utterly dominates some benchmarks with busy waiting, but at least it
doesn't create lock contention while doing so.

There's not a real race here, but it makes helgrind happy and is arguably
less prone to future errrors.

b79b5739c9 add rust_uv_loop_delete to rustrt.def.in 2012-02-28 17:56:15 -08:00
Jeff Olson
b4c88cdcec add uv::loop_delete() 
because of the last change, the loop ptr is no longer cleaned up
when the loop exits. This api call addresses that. Sadly, the loop
ptr is not "reusable" across multiple calls to uv::run().

ffad8d7f0c everything is laid out and working through a basic hw 
the core impl is there, with a async handle in place
to take incoming operations from user code. No actual
uv handle/operations are implemented yet, though.

b3f77bf927 rt: Change the way the kernel exits to avoid pthread leaks 
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.

e4c027446e Revert "rt: Reconfigure the C stack for valgrind each time it's used" 
This reverts commit 859e025652.

This ended up not fixing the '0 bytes lost' problem and has some performance
impact.

9f49293232 rt: Initialize Windows CRITICAL_SECTION with non-zero spin count 
If a CRITICAL_SECTION is not initialized with a spin count, it will
default to 0, even on multi-processor systems. MSDN suggests using
4000. On single-processor systems, the spin count parameter is ignored
and the critical section's spin count defaults to 0.

For Windows >= Vista, extra debug info is allocated for
CRITICAL_SECTIONs but not released in a timely manner. Consider using
InitializeCriticalSectionEx(CRITICAL_SECTION_NO_DEBUG_INFO).

d01e7cd340 Represent boxed ifaces in a way similar to functions 
They are now a (dictptr, box) pair, where box is a regular boxed
representation of the inner type. This cuts down on some special
case code.

Also removes some code from trans::base that was moved to shape but
then somehow restored in trans::base through a bad merge.
