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.

f6117173c9 Allocate rust_ivec buffers out of the kernel pool 
The duplication of upcalls is due to the fact that the runtime is
shared between stage0/rustc and stage1/rustc. Once snapshots are
updated, they should be de-duplicated.

681c063ec0 Conservatively serialize nearly all upcalls. Successfuly ran make check with RUST_THREADS=8, so we're probably fairly safe now. In the future we can relax the synchronization to get better performance. 2011-06-27 09:58:39 -07:00

c4f9bd9470 Re-enabled join. 2011-06-15 18:16:59 -07:00
Eric Holk
d1857d30fc This is the mega-ucontext commit. It replaces the task switching mechanism with a new one inspired by ucontext. It works under Linux, OS X and Windows, and is Valgrind clean on Linux and OS X (provided the runtime is built with gcc). 
This commit also moves yield and join to the standard library, as requested in #42. Join is currently a no-op though.

52c4c9014f Encode meta tags in the crate and start sketching enhanced logic for resolving crate "use" directives. 
Now with extra "works on OSX" kludging.

e35984b6c6 Introduce str_slice runtime function 
This reduces the time to execute the new lib-str tests from 1:40ish to a few
seconds and will eventually allow the full lib-sha1 test to run in a
reasonable amount of time. XFAIL lib-str in stage0 - it will run very slowly
until the next snapshot.

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

9a7576fe2c Move to macro-based logging checks in the C++ code 
No functions should be called for log statements that turn out to be
inactive.

a045514477 Start making the standard-lib utf-8 aware 
Finally implements _str.is_utf8, adds from_chars, from_char, to_chars,
char_at, char_len, (push|pop|shift|unshift)_char. Also, proper
character I/O for streams.

441697ab35 Extend stream functionality 
Writer and reader streams now come with methods to write and read
little-endian numbers. Whether that is the right place for such
methods is debatable, but for now, that's where they live.

will, given a pathname, determine whether it is a directory or not.
