6cae59b1e7 Use TIMERS_UNLOCK. 2005-11-01 07:05:32 +00:00
David Xu
53bbdf8646 Add code to handle timer_delete(). The timer wrapper code is completely
rewritten, now timers created with same sigev_notify_attributes will
run in same thread, this allows user to organize which timers can
run in same thread to save some thread resource.

a091d823ad Import my recent 1:1 threading working. some features improved includes:
1. fast simple type mutex.
 2. __thread tls works.
 3. asynchronous cancellation works ( using signal ).
 4. thread synchronization is fully based on umtx, mainly, condition
    variable and other synchronization objects were rewritten by using
    umtx directly. those objects can be shared between processes via
    shared memory, it has to change ABI which does not happen yet.
 5. default stack size is increased to 1M on 32 bits platform, 2M for
    64 bits platform.
As the result, some mysql super-smack benchmarks show performance is
improved massivly.

c5bfff3bab Use the recently exposed fs/gs set functions when compiling libthr to
run as a 32 bit support library for an amd64 kernel.  32 bit consumers of
libthr have zero chance of running on an amd64 kernel since we don't
implement the i386_set_ldt() family of functions.  Note that this commit
doesn't make it actually work, it just removes one more obstacle.

5dbd7addb0 1. Now that it's a thread's state is changed from within the kernel, where
no userland locks are heald, the dead thread lock can no longer protect
   access to it. Therefore, instead of using an if (!dead)...else clause
   after walking the active threads list test the thread pointer before
   deciding not to walk the dead threads list. If the thread pointer is null
   it means it was not found in the active threads list and the dead threads
   list should be checked.

2. Do not free the stack of a thread that is not marked dead. This is the
   2nd and final part of eliminating the race to free a thread's stack.

401901ac43 Close a race between a thread exiting and the freeing of it's stack.
After some discussion the best option seems to be to signal the thread's
death from within the kernel. This requires that thr_exit() take an
argument.
