bc5d6aefda Added a task wakeup callback. Closes #599.
The callback happens when a task moves from the "blocked" state to the
"running" state. The callback is also inherited by child tasks. There
is currently only a native API.

This code hasn't been heavily exercised yet.

022ebc198b Implementation mising features in lock_and_signal for Win32. Also lowered the minimum stack size to get the pfib benchmark to run without exhausting its address space on Windows. 2011-06-27 09:58:39 -07:00

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

4d99bf9af2 Added some locking to ports to prevent the case where two threads simultaneously wake up a task blocked on a certain port. 2011-06-27 09:58:39 -07:00

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.

d6deeffd95 Change the setup so that rust_activate_glue returns to rust_exit_task_glue
and rust_exit_task_glue calls the rust main.

This is simpler since we only need to setup one frame. It also matches
what ld.so does, so gdb is happy and stops a backtrace at rust_exit_task_glue
instead of continuing past whatever function happened to be before
rust_exit_task_glue is the object file.

This is the rt part and should be merged after the rust0 part.

a3ff02f126 Split start into rustc and rustboot versions. This introduces a bit of
duplication, but we will hopefully drop the rustboot one soon.

This is also a preparation for changing the rustc one to have the activate glue
return to the exit glue which will then call the main function.

This (returning to the function that calls main) matches what happens when
loader stats a program or a new thread. It lets gdb produce good backtraces
and should help with EH too.

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

inactive.

73fd87baf5 Don't attempt to wake tasks that aren't blocked.
It's possible for a supervised task to kill and wake its supervising
task then immediately try to wake it again if the supervising task
has joined the supervised. This is the easiest way to prevent that.
