b970563fe3 Patchwork of attempted fixes to effect system and gc system; eventually give up and disable it entirely in the runtime. Will need extensive reworking. 2010-09-29 17:22:13 -07:00

f985fded3e Added lock_and_signal::signal_all(), and made the rust_kernel::join() use wait instead of yield. 2010-09-10 14:38:31 -07:00

616b7afb72 Tidy up the sync dir, remove dead or mis-designed code in favour of OS primitives, switch rust_kernel to use a lock/signal pair and wait rather than spin. 2010-09-08 19:13:49 -07:00

13d6f87431 XFAIL many.rs since it crashes on win32, and add a time-slice sleep to the kernel message loop to get tests to finish in a sane time. 2010-09-08 15:48:18 -07:00

de611a3090 Lots of design changes around proxies and message passing. Made it so that domains can only talk to other domains via handles, and with the help of the rust_kernel. 2010-09-07 18:44:12 -07:00

f8ff013e3c Added a few utility classes, cleaned up the include order of .h files, and started to make the Rust kernel own domain message queues rather than the Rust domains themselves. 2010-09-07 18:41:07 -07:00

4e355aebf7 When vec growth results in a newly allocated (extended) buffer, copy existing elements over via element-wise copy, not flat memcpy. Introduce new vec growth glue to achieve this. 2010-09-03 16:18:32 -07:00

64ff82ecf9 Implemented an lock free queue based on this paper http://www.cs.rochester.edu/~scott/papers/1996_PODC_queues.pdf, the "lock free queue" we had before wasn't lock free at all. 2010-08-24 21:07:14 -07:00

2c1ec6771b Lots of changes around memory managment in the Runtime. Added memory regions and fixed race caused by calling rust_srv::malloc() from multiple threads when sending messages. 2010-08-17 23:49:57 -07:00
Michael Bebenita
9fa2b53d8c Add a "special" rust_log flag to be used for debugging in cases where the full log output prevents races from occurring. 2010-08-17 23:49:57 -07:00
Michael Bebenita
e20752de68 Added labels to blocking conditions. 2010-08-17 23:49:57 -07:00

5d98a311e4 Putting out the burning tree on Windows. Turns out you can completely starve threads by not yielding on windows/vmware, really weird. 2010-08-16 18:44:26 -07:00

73ee16b1a4 A little tidy-up that should have gone in with 4e376852e7. 2010-08-12 19:20:29 -07:00

22719e45b8 Remove commented-out code that slipped in during last commit. 2010-08-11 16:10:44 -07:00

74e12fcef6 Ignore upcall_flush for channels that are disassociated from ports. This makes task-comm-10 break a little less hard, but it still leaks because messages pending in the channel are never freed. 2010-08-11 16:08:45 -07:00
Michael Bebenita
d584de7a37 Made ref_count a word sized value. 2010-08-11 16:08:45 -07:00

f307688bf4 Add native vec[u8] to str converter. Put in workaround for leak in str to vec[u8] converter. Add testcase exercising both. Drive-by fix a potential array-out-of-bounds write on rust_str buffers. 2010-08-11 16:06:45 -07:00

97d6342bf0 Synthesize a flush_chan upcall right before a channel's ref_count drops to zero. This should only happen in the Rust code and not in the drop glue, or on the unwind path. This change allows the task owning the channel to block on a flush and delete its own channel. This change also cleans up some code around rust_port and rust_chan. 2010-08-09 08:15:34 -07:00
