	prevent spurious CYG_TEST_NA.

2003-02-24  Jonathan Larmour  <[e-mail]>

2002-11-10  Nick Garnett  <[e-mail]>

	* src/signal.cxx: Added three exportable routines that may be used
	by other packages to manipulate the signal mask, test for
	deliverable signals, and have signals delivered at controlled
	points.

2002-11-05  Jonathan Larmour  <[e-mail]>

	storage destructors, set the thread's value associated with the
	current key to NULL before invoking the destructor.

2002-02-14  Nick Garnett  <[e-mail]>

	* doc/posix.sgml: Generally fixed up and reformatted to make this
	file readable by mere humans. Some omissions and outdated
	information fixed, but not substantially changed from the
	original.

	* cdl/posix.cdl: Changed some definitions and dependencies so that
	disabling the timers does not disable threads too. This was
	largely a consequence of trying to document the behaviour of these
	options.
	
2002-02-14  Jonathan Larmour  <[e-mail]>

	* doc/posix.sgml: New file, originally accompanied by this ChangeLog:
	2001-12-22  Jonathan Larmour  <[e-mail]>
	
		* ecos-elix.sgml: Do a minor cleanup of the function prototype
		layouts.
		Should be done better than this, but this is at least not
		_completely_ wrong any more.
		Also several more layout problems due to incorrect tags fixed.
	
	2001-12-07  Jonathan Larmour  <[e-mail]>
	
		* ecos-elix.sgml: Add getcwd as supported now.
	
	2001-12-06  Jonathan Larmour  <[e-mail]>
	
		* ecos-elix.sgml: Created from old framemaker version.
	
2002-01-21  Jonathan Larmour  <[e-mail]>

	* src/sched.cxx (sched_get_priority_min): Don't allow idle thread
	priority as a valid priority.
	Case #106952.

2001-12-11  Nick Garnett  <[e-mail]>

	* tests/mqueue2.c (cyg_user_start): Added CYG_TEST_INIT() to
	NOTAPPLICABLE variant, otherwise the order of breakpoints are all
	wrong and the testfarm registers a failure.

2001-11-06  Gary Thomas  <[e-mail]>

	* include/muttypes.h: Need <pkgconf/kernel.h> configuration info,
	otherwise structures defined here could have the wrong size.

2001-10-25  I-Jui Sung <[e-mail]>

	* src/mqueue.cxx (do_mq_unlink): Nullify table entries' mq as this
	is used by mq_open to see if the entry is used.

2001-10-11  Jesper Skov  <[e-mail]>

	* tests/mutex3.c: Fixed warning. 
	(new_thread): Fixed allocation: increase counter
	before starting threads which have been allocated resources.

	* tests/signal2.c (cause_illegal_access): Fix warning.

2001-10-10  Jesper Skov  <[e-mail]>

	* cdl/posix.cdl: Only build sem.cxx when the semaphores component
	is enabled.

2001-10-09  Jonathan Larmour  <[e-mail]>

	members. Conditionalize declaration of 
	cyg_posix_pthread_release_thread().	

	* cdl/posix.cdl (CYGPKG_POSIX_CLOCKS): new option to separately
	configure posix clocks from timers.
	(CYGPKG_POSIX_TIMERS): require clocks and signals.

	* include/time.h: Make proper ISO C. Conditionalize on
	CYGPKG_POSIX_TIMERS correctly wrt the above change.

	* src/pthread.cxx (posix_asr): Call signal and timer subsystems
	conditionally.

	* src/pthread.cxx (pthread_reap): Don't destroy signal handling
	fields if there is no signal handling subsystem.
	(cyg_posix_pthread_release_thread): Conditionalize on signals.
	(pthread_create): Init signal subsys conditionally.

	* src/signal.cxx (sleep): Move to...

	* src/time.cxx: ...here.
	Conditionalize throughout depending on whether it's POSIX clocks
	or more specifically POSIX timers.
	(nanosleep): Use PTHREAD_TESTCANCEL() not pthread_testcancel().
	Get current thread from kernel not pthreads to remove pthread
	dependency.

2001-10-09  Jesper Skov  <[e-mail]>

	* tests/signal2.c: Also do NA check for signals.

2001-10-01  Jonathan Larmour  <[e-mail]>

	POSIX thread priority description.

2001-09-28  Jesper Skov  <[e-mail]>

	16. This allows service threads (such as DHCP thread) to run when
	started from main().

2001-09-10  Jonathan Larmour  <[e-mail]>

	* include/pthread.h: Separate mutex and condvar API into separate
	header file to fix configury problems.
	* include/mutex.h: New file for the above.
	* cdl/posix.cdl: provide the correct configury for the isoinfra
	package to include the above file.
	* cdl/pthread.cdl: Move _POSIX_PTHREAD_PRIO_INHERIT and
	_POSIX_THREAD_PRIO_PROTECT to cdl/posix.cdl.
	
2001-09-07  Jonathan Larmour  <[e-mail]>

	(sched_get_priority_min): Use MIN not MAX.

2001-09-06  Jesper Skov  <[e-mail]>

	* cdl/posix.cdl: Moved signal implements statements to the
	CYGPKG_POSIX_SIGNALS component.

2001-08-06  Jonathan Larmour  <[e-mail]>

	* cdl/posix.cdl: Reorganize dependencies so that signals, timers
	and pthreads really can be disabled, and the relevant files don't
	get built.
	Build new mutex.cxx file.
	Remove duplicate CYGPKG_POSIX_SCHED dependency for pthreads.

	* include/limits.h: Don't include irrelevant header dependencies.

	* include/muttypes.h: New type defining mutex/cond var types separately
	from other pthread types.

	* include/sigsetjmp.h: Don't include irrelevant header dependencies.
	Rewrite sigsetjmp in a much more compiler friendly (and readable)
	way with less type punning.

	* src/misc.cxx: Don't include sysconf cases when pthreads or
	CYGPKG_POSIX_TIMERS not enabled.

	* src/mutex.cxx: New file, broken out of pthreads.cxx, as most
	of it is not fixed to the pthreads implementation, and I've fixed
	the bits that were too tied to it.

	* src/pprivate.h: Conditionalize definitions that are specific
	to CYGPKG_POSIX_PTHREAD. Ditto for prototypes for CYGPKG_POSIX_SIGNALS
	and CYGPKG_POSIX_TIMERS. Move PTHREAD_ENTRY/RETURN etc. macros
	here so they can be used throughout the package.

	* src/pthread.cxx: Remove mutex/cond var implementation, and
	entry/return macros, as per above.

	* src/signal.cxx (cyg_sigqueue): Don't just set non-queueable signals 
	pending - also forcibly wake up any blocked threads.
	(siglongjmp): Use new layout of sigjmp_buf.

	* tests/mutex3.c:
	* tests/pthread1.c:
	* tests/pthread2.c:
	* tests/pthread3.c:
	* tests/signal1.c:
	* tests/sigsetjmp.c:
	* tests/timer1.c:
	* tests/tm_basic.cxx:
	Correct configuration dependencies, and do NA appropriately.
	
2001-08-03  Nick Garnett  <[e-mail]>

	Imported from a development branch:
	
	2001-06-27  Nick Garnett  <[e-mail]>

		* tests/pthread3.c:
		Modified the loop that waits for the threads to get going so that
		it will function correctly in an SMP system, where the threads
		will run in parallel.

		* tests/mutex3.c: Disabled this test for SMP systems. It depends
		too much on predicting the priority-driven execution order of the
		threads. In an SMP system, some threads will run in parallel and
		falsify the assumptions.

	2001-05-25  Nick Garnett  <[e-mail]>

		* src/signal.cxx (siglongjmp): Minor change to satisfy latest C++
		compiler.

2001-06-14  Jonathan Larmour  <[e-mail]>

	* src/pthread.cxx (pthread_attr_setstacksize): Correct stack
	size assertion.

2001-06-12  Jonathan Larmour  <[e-mail]>

	* src/pthread.cxx (MAIN_DEFAULT_STACK_SIZE): Define to use at
	least PTHREAD_STACK_MIN for main_stack.

2001-05-01  Nick Garnett  <[e-mail]>

	[x86 branch]
	* tests/signal2.c (cause_illegal_access): Added code for I386
	architecture to provoke General Protection Fault.
