+

+	* pthread_cancel.c (pthread_cancel): Adapted to use auto-detected

+	QueueUserAPCEx features at run-time.

+	(ptw32_RegisterCancelation): Drop in replacement for QueueUserAPCEx()

+	if it can't be used. Provides older style non-preemptive async

+	cancelation.

+	* pthread_win32_attach_detach_np.c (pthread_win32_attach_np):

+	Auto-detect quserex.dll and the availability of alertdrv.sys;

+	initialise and close on process attach/detach.

+	* global.c (ptw32_register_cancelation): Pointer to either

+	QueueUserAPCEx() or ptw32_RegisterCancelation() depending on

+	availability. QueueUserAPCEx makes pre-emptive async cancelation

+	possible.

+	* implement.h: Add definitions and prototypes related to QueueUserAPC.

+

+2004-05-16  Panagiotis E. Hadjidoukas <peh at hpclab.ceid.upatras.gr>

+

+	* QueueUserAPCEx (separate contributed package): Provides preemptive

+	APC feature.

+	* pthread_cancel.c (pthread_cancel): Initial integration of

+	QueueUserAPCEx into pthreads-win32 to provide true pre-emptive

+	async cancelation of threads, including blocked threads.

+

+	* pthread_cancel.c (AMD64): Add architecture specific Context register.

+	* ptw32_getprocessors.c: Use correct types (DWORD_PTR) for mask

+	variables.

+

+	close a memory leak.

+

+

+	* sem_timedwait.c (sem_timedwait): Fix timeout calculations.

+

+2003-10-20  Alexander Terekhov  <TEREKHOV at de.ibm.com>

+

+	* pthread_mutex_timedlock.c (ptw32_semwait): Move to individual module.

+	* ptw32_semwait.c: New module.

+	* pthread_cond_wait.c (ptw32_cond_wait_cleanup): Replace cancelable

+	sem_wait() call with non-cancelable ptw32_semwait() call.

+	* pthread.c (private.c): Re-order for inlining. GNU C warned that

+	function ptw32_semwait() was defined 'inline' after it was called.

+	* pthread_cond_signal.c (ptw32_cond_unblock): Likewise.

+	* pthread_delay_np.c: Disable Watcom warning with comment.

+	* *.c (process.h): Remove include from .c files. This is conditionally

+	included by the common project include files.

+

+2003-10-20  James Ewing  <james.ewing at sveasoft.com>

+

+	* ptw32_getprocessors.c: Some Win32 environments don't have

+	GetProcessAffinityMask(), so always return CPU count = 1 for them.

+	* config.h (NEED_PROCESSOR_AFFINITY_MASK): Define for WinCE.

+	

+2003-10-15  Ross Johnson  <ross at callisto.canberra.edu.au>

+

+	* Re-indented all .c files using default GNU style to remove assorted

+	editor ugliness (used GNU indent utility in default style).

+

+2003-10-15  Alex Blanco  <Alex.Blanco at motorola.com>

+

+	* sem_init.c (sem_init): Would call CreateSemaphore even if the sema

+	struct calloc failed; was not freeing calloced memory if either

+	CreateSemaphore or CreateEvent failed.

+

+2003-10-14  Ross Johnson  <ross at callisto.canberra.edu.au>

+

+	* pthread.h: Add Watcom compiler compatibility. Esssentially just add

+	the cdecl attribute to all exposed function prototypes so that Watcom

+	generates function call code compatible with non-Watcom built libraries.

+	By default, Watcom uses registers to pass function args if possible rather

+	than pushing to stack.

+	* semaphore.h: Likewise.

+	* sched.h: Likewise.

+	* pthread_cond_wait.c (ptw32_cond_wait_cleanup): Define with cdecl attribute

+	for Watcom compatibility. This routine is called via pthread_cleanup_push so

+	it had to match function arg definition.

+	* Wmakefile: New makefile for Watcom builds.

-
-	* pthread_setschedparam.c (pthread_setschedparam): Attempt to map
-	all priority levels between max and min (as returned by
-	sched_get_priority_min/max) to reasonable Win32 priority levels - i.e.
-	levels between THREAD_PRIORITY_LOWEST/IDLE to THREAD_PRIORITY_LOWEST and
-	between THREAD_PRIORITY_HIGHEST/TIME_CRITICAL to THREAD_PRIORITY_HIGHEST
-	while others remain unchanged; record specified thread priority level
-	for return by pthread_getschedparam.
-
-	Note that, previously, specified levels not matching Win32 priority levels
-	would silently leave the current thread priority unaltered.
-
-	* pthread_getschedparam.c (pthread_getschedparam): Return the priority
-	level specified by the latest pthread_setschedparam or pthread_create rather
-	than the actual running thread priority as returned by GetThreadPriority - as
-	required by POSIX. I.e. temporary or adjusted actual priority levels are not
-	returned by this routine.
-
-	* pthread_create.c (pthread_create): For priority levels specified via
-	pthread attributes, attempt to map all priority levels between max and
-	min (as returned by sched_get_priority_min/max) to reasonable Win32
-	priority levels; record priority level given via attributes, or
-	inherited from parent thread, for later return by pthread_getschedparam.
-
-	* ptw32_new.c (ptw32_new): Initialise pthread_t_ sched_priority element.
-
-	* pthread_self.c (pthread_self): Set newly created implicit POSIX thread
-	sched_priority to Win32 thread's current actual priority. Temporarily
-	altered priorities can't be avoided in this case.
-
-	* implement.h (struct pthread_t_): Add new sched_priority element.
