5302cde188 Made task threads wait instead of sleep, so they can be woken up. This appears to give us much better parallel performance. 
Also, commented out one more unsafe log and updated rust_kernel.cpp to compile under g++

e697a52359 Adding a function to stdlib to set the min stack size, for programs 
that absolutely will not succeed with a large default stack. This
should be removed once we have stack grown working.

Also updated word-count to succeed under the new test framework.

62bc6b5113 Per-thread scheduling. Closes #682. 
Tasks are spawned on a random thread. Currently they stay there, but
we should add task migration and load balancing in the future. This
should drammatically improve our task performance benchmarks.

Eric Holk
8878b128ba More work on word-count. 
Updated the MapReduce protocol so that it's correct more often. It's
still not perfect, but the bugs repro less often now.

Also found a race condition in channel sending. The problem is that
send and receive both need to refer to the _unread field in
circular_buffer. For now I just grabbed the port lock to send. We can
probably get around this by using atomics instead.

d79afd7916 Improving move semantics for channel operations. 
This lets us un-XFAIL task-comm-10.rs.

Eric Holk
3ae4dcd41e Lots of work on memory tracking and channels. 
We're trying to get closer to doing correct move semantics for channel
operations. This involves a lot of cleanup (such as removing the
unused sched parameter from rust_vec constructor) and making
circular_buffer kernel_owned.

Added tagging for memory allocations. This means we give a string tag
to everything we allocate. If we leak something and TRACK_ALLOCATIONS
is enabled, then it's much easier now to tell exactly what is leaking.

Brian Anderson
a467e8e4e6 Add a huge hack to allow the test runner to continue if a single task leaks 
This is just until unwinding works. Adds a flag to the runtime to turn
the memory leak checks on task destruction into warnings instead of fatal
errors. I am so sorry.

01a52d728c Add an unsupervise builtin and function to std::task 
Calling task::unsupervise de-parents the current task, with the result

Brian Anderson
4738cf83b0 Move the responsibility for process failure from tasks to the scheduler 
When the root task fails the process fails. Failures on other tasks propagate
up the task tree. Failures on non-root tasks without parents just
(theoretically) unwind and disappear.

3958c72cd8 Some cleanup 2011-07-07 18:32:45 -07:00
Eric Holk
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.
 2011-07-07 18:22:27 -07:00

f6e37f659c Made TRACK_ALLOCATIONS add only constant time overhead. This makes it

8acadb17c2 Work on debugging race conditions. 
Ports and channels have been moved to the kernel pool, since they've
been known to outlive their associated task. This probably isn't the
right thing to do, the life cycle needs fixed instead.

Some refactorying in memory_region.cpp. Added a helper function to
increment and decrement the allocation counter. This makes it easier
to switch between atomic and non-atomic increments. Using atomic
increments for now, although this still does not fix the problem.

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.

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.

4e59b0be54 Sync rust_chan's deref() method with rustc's code. 
If the channel is associated with a port then the destructor will assert.
Additionally, destruction of the object is not always appropriate. This brings
the deref() method into sync with the behavior of generated rust code which
only invokes destroy() once the reference count goes to 0.

02a5949aba Add macro for refcounting runtime structures. 
The macro with the extra dtor parameter is intended for structures like
rust_chan which may not necessarily delete themselves when the ref count
becomes 0. This functionality will be used in an upcoming changeset.
 2011-07-01 16:59:10 -07:00

73cc624e8e Move the channel destroy code into rust_chan. 
This lets native code more easily destroy channels since directly deleting a
channel is not always the right way to destroy it.

09921cf86f Move channel cloning logic into a method on rust_chan.

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.

copies of memcheck.h and valgrind.h, effectively backporting
the fix from the unreleased 3.6.2. The commit simply applies
the gcc 'unused' attribute to the relevant declarations.

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

f6be25a870 Update foregoing patches to leave rust_crate alone. 
Apparently it can't live in the main binary, since on non-Linux
platforms, dynamics libs won't find symbols in the binary. This
removes the crate_map pointer from rust_crate again, and instead
passes it as an extra argument to rust_start. Rustboot doesn't pass
this argument, but supposedly that's okay as long as we don't actually
use it on that platform.

148e6f7b00 Make log the log level configurable per module 
This overloads the meaning of RUST_LOG to also allow
'module.submodule' or 'module.somethingelse=2' forms. The first turn
on all logging for a module (loglevel 3), the second sets its loglevel
to 2. Log levels are:

 0: Show only errors
 1: Errors and warnings
 2: Errors, warnings, and notes
 3: Everything, including debug logging

Right now, since we only have one 'log' operation, everything happens
at level 1 (warning), so the only meaningful thing that can be done
with the new RUST_LOG support is disable logging (=0) for some
modules.

TODOS:
 * Language support for logging at a specific level
 * Also add a log level field to tasks, query the current task as well
   as the current module before logging (log if one of them allows it)
 * Revise the C logging API to conform to this set-up (globals for
   per-module log level, query the task level before logging, stop
   using a global mask)

Implementation notes:

Crates now contain two extra data structures. A 'module map' that
contains names and pointers to the module-log-level globals for each
module in the crate that logs, and a 'crate map' that points at the
crate's module map, as well as at the crate maps of all external
crates it depends on. These are walked by the runtime (in
rust_crate.cpp) to set the currect log levels based on RUST_LOG.

These module log globals are allocated as-needed whenever a log
expression is encountered, and their location is hard-coded into the
logging code, which compares the current level to the log statement's
level, and skips over all logging code when it is lower.

295c54e10f Remove the assumption that circular_buffer's buffer has a power of two size 
It was not obvious how to make this implementation work when the unit size
was not also a power of two, so for now just make the buffer size a multiple
of the unit size so it can pass all the tests.

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.
