changelog

pthread source code,you can compile directly

	(PTW32_DLLPORT): Now only defined if _DLL defined.
	(_errno): Compiler directive was incorrectly including prototype.
	* sched.h: Conditionally added some #defines from config.h
	needed when not building the library.
	* semaphore.h: Replace an instance of NEED_SEM that should
	have been NEED_ERRNO. This change currently has nil effect.

	* GNUmakefile: Correct some recent changes.

	* Makefile: Add rule to generate pre-processor output.

2002-02-23  Ross Johnson  <rpj at setup1.ise.canberra.edu.au>

	* pthread_rwlock_timedrdlock.c: New - untested.
	* pthread_rwlock_timedwrlock.c: New - untested.
	
	* Testsuite passed (except known MSVC++ problems)

	* pthread_cond_destroy.c: Expand the time change
	critical section to solve deadlock problem.

	* pthread.c: Add all remaining C modules.
	* pthread.h: Use dllexport/dllimport attributes on functions
	to avoid using pthread.def.
	* sched.h: Likewise.
	* semaphore.h: Likewise.
	* GNUmakefile: Add new targets for single translation
	unit build to maximise inlining potential; generate
	pthread.def automatically.
	* Makefile: Likewise, but no longer uses pthread.def.

2002-02-20  Ross Johnson  <rpj at setup1.ise.canberra.edu.au>

	* pthread_cond_destroy.c (pthread_cond_destroy):
	Enter the time change critical section earlier.

2002-02-17  Ross Johnson  <rpj at setup1.ise.canberra.edu.au

	* Testsuite passed.

	* pthread_timechange_handler_np.c: New; following
	a suggestion from Alexander Terekhov that CVs should
	be broadcast so that they all re-evaluate their
	condition variables and reset a new timeout if
	required, whenever an application receives a
	WM_TIMECHANGE message. This message indicates that
	the system time has been changed. Therefore, CVs
	waiting for a timeout set as an abs_time will possibly
	not wake up at the expected time. Some applications
	may not be tolerant of this.
	* pthread_cond_init.c: Add CV to linked list.
	* pthread_cond_destroy.c: Remove CV from linked list.
	* global.c (ptw32_cond_list_head): New variable.
	(ptw32_cond_list_tail): New variable.
	(ptw32_cond_list_cs): New critical section.
	* ptw32_processInitialize (ptw32_cond_list_cs): Initialize.
	* ptw32_processTerminate (ptw32_cond_list_cs): Delete.


	* Reduce executable size.
	  -----------------------
	When linking with the static library, only those
	routines actually called, either directly or indirectly
	should be included.

	[Gcc has the -ffunction-segments option to do this but MSVC
	doesn't have this feature as far as I can determine. Other
	compilers are undetermined as well. - rpj]

	cancelation point. Deferred cancels will interrupt the
	wait.

2002-02-07  Ross Johnson  <rpj at setup1.ise.canberra.edu.au

	* misc.c (ptw32_new): Add creation of cancelEvent so that
	implicit POSIX threads (Win32 threads with a POSIX face)
	are cancelable; mainly so that pthread_delay_np doesn't fail
	if called from the main thread.

	from here; now in ptw32_new().

2002-02-04  Max Woodbury <mtew at cds.duke.edu>

	Reduced name space pollution.
	-----------------------------
	When the appropriate symbols are defined, the headers
	will restrict the definitions of new names. In particular,
	it must be possible to NOT include the <windows.h>
	header and related definitions with some combination
	of symbol definitions. Secondly, it should be possible
	that additional definitions should be limited to POSIX 
	compliant symbols by the definition of appropriate symbols.

	* pthread.h: POSIX conditionals.
	* sched.h: POSIX conditionals.
	* semaphore.h: POSIX conditionals.

	* semaphore.c: Included <limits.h>.
	(sem_init): Changed magic 0x7FFFFFFFL to INT_MAX.
	(sem_getvalue): Trial version.
