1998-10-14  Hugo Tyson  <[e-mail]>

	* include/pkgconf/uitron.h: 
	Add configury for create/delete of tasks.
	
	* include/uit_func.h: 
	Add prototypes for cre/del_tsk(); correct comment in exd_tsk().
	
	* include/uit_func.inl: 
	Implement cre/del_tsk() and complete exd_tsk().
	Improve NULL/NADR checking on other cre/del calls.

	* src/uit_func.cxx (cyg_uitron_start): 
	Deal better with start tasks stuff, for task create/delete.

	* src/uit_objs.cxx: 
	Support CYG_UIT_TASK_NONE(...) task constructor for those tasks
	which do not initially exist

	* tests/PKGconf.mak:
	Add new tests test8.c, testcx[678].cxx to the build.

	* tests/test6.c:
	Tidy comments, untabify.
	
	* tests/test7.c:
	Tidy comments, untabify, test creation with NADR record pointer.
	No impact from the new cre/del_tsk() functionality on test7, since
	a task may only be deleted when it is dormant, so deletion is NOT
	another way out of a waiting state.
	
	* tests/test8.c:
	New test, tests cre_tsk() and del_tsk() and exd_tsk() ie. the
	creation and deletion of tasks.

	* tests/testcx6.cxx:
	* tests/testcx7.cxx:
	* tests/testcx8.cxx:
	New tests, C++ versions of tests 6, 7, and 8.

1998-10-09  Hugo Tyson  <[e-mail]>

	* tests/test7.c: 
	Test interactions with deleting objects (as applicable) and
	killing, signalling and the like.  Also test killing the task
	after other treatments more generically.

	* tests/test6.c (task1): 
	Change "N/A:" to "N/A" in the exit message when we didn't actually
	do any testing due to create/delete being disabled for all object
	types.

1998-10-08  Hugo Tyson  <[e-mail]>

	In general, these changes are to support create/delete of uITRON
	objects; this requires that an object can be destroyed whilst
	there are threads waiting on it, and that they shall be awoken
	with a specific return code E_DLT.  The implementation uses an
	array of pointers in addition to the array of objects: ptrs[N]
	should either be NULL or &objs[N] in this version.  That
	restriction is not checked, in order that in future, true dynamic
	allocation can be used, and ptrs[N] could point anywhere.  The
	implications of this are mainly in the area of getting the
	addresses of objects, via the ptr array or from the object array?
	The config of whether there is a ptr array is per object type.

	* include/pkgconf/uitron.h: 
	Configury of the existence or not of create/delete for object
	type: initially only SEMAS, MBOXES, FLAGS.
	Configury of the number of objects created initially, if cre/del
	are enabled.

	* tests/test6.c:
	* tests/test7.c:
	* tests/PKGconf.mak:
	Two new test programs (duh!): test6 tests create and delete of
	SEMAS, MBOXES, FLAGS explicitly, for bad params handling, ability
	to use after deletion and recreation &c &c.  test7 tests the
	semantics of sleeping on some synchronization primitive, permed
	with suspension, signalling, killing, releasing and so forth.
	Both will migrate into C++ versions also in future.

	* include/uit_func.h:
	Enable cre/del_{mbx,flg,sem} prototypes.

	* include/uit_func.inl:
	Implement cre/del_{mbx,flg,sem} depending on configury, and handle
	the pointer arrays generally in other client routines.

	* include/uit_objs.hxx:
	Define the pointer arrays for access to created objects.

	* include/uit_type.h:
	Enable definitions of the structures used in create calls.
	
	* src/uit_func.cxx:
	Initialization code for the pointer arrays, akin to the task
	startup code.

	* src/uit_objs.cxx:
	Instantiate the pointer arrays themselves.


1998-09-25  Bart Veer  <[e-mail]>

	* include/pkgconf/uitron.h:
	PR 17482: added #ifdef protection. If CYGPKG_UITRON_MEMPOOLFIXED
	is not defined then the contained option
	CYGNUM_UITRON_MEMPOOLFIXED may not be defined either. Ditto for
	CYGNUM_UITRON_MEMPOOLVAR which suffers from the same problem.
	And ditto for CYGPKG_UITRON_SEMAS

1998-09-20  Mark Galassi  <[e-mail]>

	* include/pkgconf/uitron.h: added one or two CDL doc strings.

Tue Sep 15 19:12:28 1998  David Moore  <[e-mail]>

	* include/pkgconf/uitron.h: Cleaned up comments.

1998-09-12  Mark Galassi  <[e-mail]>
small changes to the descriptive information in the uITRON CDL

1998-09-12  Mark Galassi  <[e-mail]>

	* include/pkgconf/uitron.h: small editing of the description
	fields: renamed things like <name> to NAME, so that it does not
	confuse SGML when incorporated into the documentation.
	Also added various "doc" fields to the CFG_DATA comments.

Wed Sep  9 18:36:15 1998  Hugo Tyson  <[e-mail]>

	* include/uit_func.inl: 
	* include/uit_objs.hxx: 
	* src/uit_objs.cxx: 
	Condition features on CYGPKG_UITRON_SEMAS [for example] as well as
 	0 < CYG_UITRON_NUM( SEMAS ) so that we get warning free
	compilation with no semas enabled.  Ditto for flags, mboxes,
	mempools fixed and variable, alarms and cyclics.
	
	* include/pkgconf/uitron.h: 
	Add a couple of requires statements from cyclics and alarms on the
	kernel clock.
	Also change some grammar after review.
	Add an option (actually a pair, makes it better documentation IMO)
	to require strict semantics from the kernel setup.
	Add an option to control the optional sema initializer; it was
	omitted since the editor way of configury used a #if 0.
	
Fri Sep  4 17:54:29 1998  Hugo Tyson  <[e-mail]>

	* include/pkgconf/uitron.h: 
	Remove redundant and now unnecessary defs of CYGPKG_UITRON.

Wed Sep  2 19:06:17 1998  Hugo Tyson  <[e-mail]>

	* include/uit_func.inl: 
	Memory pools and message boxes and flags
	and cnt_sem2-type semaphores now all have absolute timeouts
	instead of relative ones in the timely wait functions.
	We add in the current time here first.

Wed Sep  2 16:45:40 1998  Hugo Tyson  <[e-mail]>

	* include/pkgconf/uitron.h (CYGDAT_UITRON_TASK_INITIALIZERS): 
	Use the new kernel thread initializer with priority and thread
	name in it.

	* include/uit_func.inl: 
	* include/uit_objs.hxx: 
	* src/uit_func.cxx (cyg_uitron_start): 
	* src/uit_objs.cxx: 
	Our tasks are now Cyg_Threads rather than a derived class.
  	Original priorities of tasks are held in an array.  An accessor
 	macro is used for the off-by-one nature of uitron IDs.  The array
 	of original priorities is set up in cyg_uitron_start(), and
	created in uit_objs.cxx.
	
Wed Sep  2 15:15:26 1998  Hugo Tyson  <[e-mail]>

	* include/pkgconf/uitron.h: 
	Comment more strongly in the 'description' that the number of
	initializers better match the number of things specified.

Tue Sep  1 19:00:02 1998  Hugo Tyson  <[e-mail]>

	* include/uit_objs.hxx: 
	Do not include <cyg/kernel/kernel.h>; it is deprecated.
	Instead, include only kernel headers that are needed.

	* include/uit_func.inl (ref_sys): 
	Use new kernel function Cyg_Interrupt::interrupts_enabled()
	instead of a state variable.  Tidy up associated code.
	Include kernel headers that are needed because they were not
	included in uit_objs.hxx for tidiness.

	* src/uit_func.cxx: 
	Elide state variable that used to be used for tracking interrupt
	enabledness state.

	* tests/testcx5.cxx (task1): 
	* tests/test5.c (task1): 
	Test interrupt enable and disable stuff, and status reporting.

Tue Sep  1 15:12:29 1998  Hugo Tyson  <[e-mail]>

	* include/uit_func.inl (ref_mpf): 
	Change comment "ECC" to "eCos".

1998-08-28  Bart Veer  <[e-mail]>

	* include/uit_func.inl:
	* tests/test1.c, tests/test2.c, tests/test3.c, tests/test4.c,
	tests/test5.c, tests/testcxx.cxx, tests/testcx2.cxx,
	tests/testcx3.cxx, tests/testcx4.cxx, tests/testcx5.cxx:

	Updated for new kernel configuration option symbol names


Fri Aug 28 09:21:55 1998  Jonathan Larmour  <[e-mail]>

	* src/uit_func.cxx (cyg_uitron_start): 
	Remove call to Cyg_Scheduler::start() and adjust comments to
	explain where to call it from

	* tests/test1.c, tests/test2.c, tests/test3.c, tests/test4.c, 
	  tests/test5.c, tests/testcxx.cxx, tests/testcx2.cxx, 
	  tests/testcx3.cxx, tests/testcx4.cxx, tests/testcx5.cxx:
	Change the normal entry point at the top to be cyg_package_start()
	under the new startup scheme. This overrides the default package
	configuration and ensure cyg_uitron_start() gets called.
	Change the "default" entry point at the bottom (when the test is
	N/A for some reason) to cyg_start() under the new startup scheme.
	
Wed Aug 26 18:20:47 1998  Hugo Tyson  <[e-mail]>

	* include/pkgconf/uitron.h: 
	Initial version of cdl control statements for config options.
	All very groovy, and looking good IMO.
	A few FIX-MEs remain, no big deal.

Mon Aug 24 19:05:52 1998  Hugo Tyson  <[e-mail]>

	* include/pkgconf/uitron.h: 
	Change the names of config options to helpful, positive sense, and
	tidy some of the names for inclusion in the GUI tool.  Clean up
	the namespace too.
	
	* include/uit_func.h: 
	* include/uit_func.inl: 
	* src/uit_func.cxx: 
	* src/uit_objs.cxx: 
	Configure according to new option names and object construction
	macros.  Simple changes but widespread.

	* tests/test[12345].c: 
	* tests/testcx[x2345].cxx: 
	Configure according to new option names.
	Make it main( void ) to avoid a warning.

Fri Aug 21 18:45:16 1998  Hugo Tyson  <[e-mail]>

	* tests/testcx4.cxx (task1): 
	* tests/test4.c (task1): 
	* include/uit_func.inl (def_alm): 
	Tidy the alarm and timer funcs in the course of fixing a kernel
	bug actually.  Test the functionality affected by the kernel
	change a bit more.
	
Thu Aug 20 14:33:36 1998  Hugo Tyson  <[e-mail]>

	* include/uit_func.inl (ref_alm): 
	Elide an unused variable following the previous change.

Mon Aug 17 15:45:07 1998  Hugo Tyson  <[e-mail]>

	* include/pkgconf/uitron.h: 
	Add the config option CYGSEM_UITRON_PARAMS_CHECK_NADR_ONLY.
	
	* tests/testcxx.cxx: 
	* tests/testcx2.cxx: 
	* tests/testcx4.cxx: 
	Avoid testing with NULL as a bad parameter when only NADR is
	checked.  (NADR does not cast to any-pointer in C++ so we don't
	test it in these programs)  Check for NADR various places as well
	as NULL.
	
	* tests/test1.c (task1): 
	* tests/test2.c (task1): 
	* tests/test4.c (task1): 
	Avoid testing with NULL as a bad parameter when only NADR is
 	checked.  Check for NADR various places as well as NULL, and test
 	NADR as a bad param as well as NULL.


Mon Aug 17 14:45:30 1998  Hugo Tyson  <[e-mail]>

	* include/uit_func.inl:
	PR# 16536: Check for dormant tasks various places; E_OBJ
	must be returned.  All this error checking rather bloats the code,
	unfortunately.
	
	* tests/testcxx.cxx: 
	* tests/test1.c: 
	Test the new checks above.

Fri Aug 14 17:41:35 1998  Hugo Tyson  <[e-mail]>

	* include/uit_func.inl ([t]wai/pol_flg): 
	Check for zero in a wait-for-flag operation; such a wait can never
	be awakened, and so should return E_PAR.

	* tests/testcx2.cxx (task1): 
	* tests/test2.c (task1): 
	Test the above new checking.

Fri Jul 24 17:12:54 1998  Hugo Tyson  <[e-mail]>

	PR#15865
	* include/uit_func.inl: return a bool (strictly 1 or 0) for wtsk
 	rather than -1 or zero as the spec implies.
	ref_flg() ref_sem() only affected.

Fri Jul 24 13:26:51 1998  Hugo Tyson  <[e-mail]>

	PR#16531
	* include/uit_func.inl: return E_OBJ when (force)resuming a
	non-suspended task.
	* tests/test1.c: test for that error code.
	* tests/testcxx.cxx: test for that error code.

Fri Jul 24 13:02:46 1998  Hugo Tyson  <[e-mail]>

	* Changelog: Initial ChangeLog entry.
