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

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 4e376852e709844d67f94430d9dc954d5be722b4. 2010-08-12 19:20:29 -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

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

b71340552f Add names to tasks and domains. These can either be an explicit literal string
after the "spawn" keyword, or implicitly the call expression used to start the
spawn.
