	  configure.ac, config/hackt.m4: added option to re-enable the
		now-obsolete unroll phase tests in test suite.

2006-11-25	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-58:
	  dox/ChangeLog only -- improved LaTeX dependency management.

2006-11-11	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-50-test-11:
	  config/hackt.m4: renamed NO_VPATH to AUTO_CVSIGNORE, also 
		added to it a test if srcdir is writeable.
	  Make.global: now generates .cvsignore in the $(srcdir) if permitted.


	* HACKT-00-01-04-main-00-80-50-test-09:

	  Earlier in branch, phased out sequential test scripts in favor
		of Makefile-controlled concurrency in regression test suite.
	  configure.ac: new --enable-verbose-check configure option.  


2006-11-07	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-50:

2006-11-06	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-49-merged-instance-02-31:
	  Branch merge, see src/ChangeLog.


2006-10-26	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-46:
	  Confirmed against g++-4.2-20061024, noted in BUILDS.


2006-10-24	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-44:
	  config/hackt.m4: arg-enable option to turn off object alignment

	  Branch merge, summary in src/ChangeLog.


2006-10-23	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-42:
	  Make.global: 
		new srcdir_EXTRA_DIST variable, which works similar to
			EXTRA_DIST but looks only in the $(srcdir) for files.
		new echo targets: distfiles, disthook-cleanfiles,
			and srcdir-extra-dist (all listed in make help).
		Added more commends on usage of special global targets.  
	  Is now distcheck-able from a VPATH build.  
		And there was much rejoicing.  


2006-10-17	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-30-merged-instance-00-39:

		distribution removal, per Makefile.  
	  Make.global: new distdir-subdir target for manually
		building subtree of distribution for diagnostics.  


2006-08-29	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-80-05:
	  config/lexyacc.am: defined HACKT_YACC_PURE_PARSER macro.

		Fixed cvsignore target recursiveness, using Makefile.in's
		template recipe for RECURSIVE_TARGETS (MORE_RECURSIVE_TARGETS)


2006-08-09	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-54-prsim-07-06:
	  configure.ac: check for unsigned type aliases, like uchar.  


2006-08-07	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-51:
	  config/config_subst.awk: handle autoconf-2.60 substitution sugar.

2006-08-04	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-49:
	  Added MAINTAINER-checklist and CONTRIBUTORS.  


2006-07-28	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-40:
	  config/documentation.m4, configure.ac:
		added more checks for graphviz programs.  


2006-07-27	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-38:
	  scripts/tally_tests.awk now counts skipped tests.


2006-07-04	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-24-merged-cow-07:
	  Branch merge.  copy-on-write unrolling, higher-dimension
		aggregate references and collections.  
	  scripts/rm_pattern.sh: more robust file cleaning of patterns
	  config/am__remove_distdir.diff: more robust rm -rf


2006-07-01	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-20-cow-03:
	  Added scripts/rm_pattern.sh used in the definition of
		RM_PATTERN in Make.stddef.  rm residues begone!


2006-07-01	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-21:
	  config/rl_el.m4: forgot to allow header check for histedit.h
		in the check for --with-editline.  Now works with histedit.  
	  Minor provisions to enable use with bison-2.1.  Damn you, bison.  


2006-06-30	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-20-cow-02:
	  configure.ac: apply extra patch to top_builddir/Makefile:
		am__remove_distdir hacked to repeatedly try rm -rf $(distdir)
		until command succeeds because of residual files from
		recursive remove when too many files in directory.  
	  config/am__remove_distdir.diff is the patch for this.
		This patch should (IMO) be applied to automake's 
		am/distdir.am upstream source.  


2006-05-12	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-03-CHP-02-04:
	  Added vim modelines to Makefile.am snippets, lexer .ll files:
		e.g., "vim: ft=automake"


2006-05-10	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-03-CHP-02-01:
	  Make.global: cvsdiffs target now works in VPATH builds
		by switching to the $(srcdir) to run cvs diff, 
		still redirecting to the builddir's 'cvsdiffs'.  


2006-05-08	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79-03:
	  Documented config/*.m4 autoconf macros, suitable for publication.  
		Documented in the style recommended by ac-archive.sf.net.  
	  Renamed many custom-defined AC_* macros to FANG_ or HACKT_
		to not infringe upon reserved autoconf namespaces.  
		configure.ac calls to macros updated accordingly.  
	  top_builddir generates a install_transform.sh
		to assist in transforming program names.


2006-05-06	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-79:
	  Cleaned out the top-level TODO log.

	* HACKT-00-01-04-main-00-78-24-merged-prsim-04-12:
	  Branch merge of -prsim-04-12.
	  Includes minor configure test fix in config/cxx.m4 (attribute).


2006-04-26	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-20-merged-icc-01-04:
	  Merged portability and configurisms from branch.  
		Vast improvement in icc support, but it still doesn't fully
		build yet.  Punting for later, when I have time to waste.


2006-04-25	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-19-icc-01-03:
	  configure check for std::_Identity, _Select1st, _Select2nd.  


2006-04-24	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-19-icc-01-02:
	  Tons of configurisms for SGI vs. Intel hash_map.
		Checking for namespace and template argument style.  
	  Forward declaration headers fixed accordingly.  


	* HACKT-00-01-04-main-00-78-19-icc-01-01:
	  Another crack at getting icc to compile hackt.  
	  configure.ac: moved AC_HEADER_STDCXX test earlier
	  config/cxx.m4: switched the ordering of detecting compiler
		in determining the set of anal compile flags to test.
		New test to check that standard headers pass strict
		compile flags.  If not, then you're pretty sunk already!
		Attribute tests that include standard headers now use
		CONFTEST_CXXFLAGS instead of ANAL_FLAGS to forgive
		selected warnings.  
	  config/cxx_STL.m4: some new header checks
	  config/hackt.m4: new FANG_CONFTEST_FLAGS macro


2006-04-23	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-19:
	  Reasonable initial attempt to accommodates icc-9.0.
	  To be configured...
		Started to rewrite some config/cxx.m4 macros to account
		for icc differences, in particular compile flags.  
	  Global cvsignore generation is now disabled during VPATH builds.  


2006-04-23	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-18-merged-prsim-03-09:
	  Branch merge.  


2006-04-18	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-17:
	  Major standard conformance updates, tested against gcc-4.2 (pre).
	  Most affected are the util libraries.  


2006-04-13	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-15:
	  Bunch of configuration improvements, motivated by trying to get this
		damn thing to build again on a legacy sparc-sun-solaris2.9 box.
	  configure.ac: use new tests, check for int64 and uint64 before
		typedef-ing them ourselves in util/inttypes.h.
		Most notably, the anal-warning flags are applied during
		conftests so the build matches the results more properly.  
		In general, check config.log for anomalies.  
		Also inserted AC_CACHE_SAVE for checkpointing.
	  Added option to disable the default -ansi -pedantic-error flags.  
	  config/cxx.m4: improved handling and binning of warning flags, 
		and added set of tests for un-flags during AC_CHECK_ conftests.
	  config/cc.m4: special function checks for fmod and fmodf, because
		they may need libm to link properly (solaris).  
	  General configure-improvements in source tree.  


2006-04-12	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-13-merged-spec-02-04:
	  Branch merge of -spec-02-04.  


2006-04-11	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-12-merged-prsim-02-08:
	  Branch merge of -prsim-02-08.  configure.ac date bump.  


2006-04-08	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-10:
	  configure improvements: pushed generated config.h to src/__config__.h
		to eliminate super-directory references.  
	  configure.ac: AM_CONFIG_HEADER (obsolete) replaced with
		AC_CONFIG_HEADERS([src/__config__.h])
	  Make.global: echo-config target to show configure params, 
		by invoking (top_builddir)'s ocnfig.status --version
	  config/rl_el.m4: preliminary support for non-wrapped editline
		usage (without the readline symbol interface).  


2006-04-03	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-07-prsim-01-15:
	  Branch merge of -prsim-01, also bringing some configure improvements.


2006-04-02	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-05-prsim-01-14:
	  configure.ac: check for *rand48 family of stdlib C functions.  


2006-03-30	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-05-prsim-01-11:
	  Wrote some configure tests for checking usability of standard
		file descriptors with C++ file streams.  
		This achieves redirection from inside a program back to
		stdin and stdout.  


2006-03-25	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-05-prsim-01-04:
	  Added configure checks for signal.h headers.  


2006-03-19	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-03-merged-nonmeta-02-05:
	  Branch merge.


2006-03-16	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-02:
	  Removed the configure check for sqrt because we're not using it
		and it seems to be causing problems (bad test).  
		Possibly built-in funcs should be checked differently.  


2006-03-14	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-78-merged-connect-02-09:
	  Branch merge.  Major unroll/create pass improvements.  


	* HACKT-00-01-04-main-00-77-19-connect-02-09:
	  Added test for known compiler bug in the util test-suite, 
		configurating the shell script for it.  


2006-02-24	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-17-merged-maintainence-05:
	  Merged configure-maintainence revisions from branch.


2006-02-24	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-16-maintainence-05:
	  New configure macro policy:
		Instead of allowing LIBS to accumulate across many library
		check invocations, we're going to store the result of
		each library in its own _LIB variable and accumulate
		into AUTO_LIBS in configure.ac, which then becomes LIBS.
		The reason: for better control, we're no longer accumulating
		LDFLAGS and CPPFLAGS in each package check; each one produces
		its own private variable.  This results in better isolation
		for each package check, whish is made possible by use of
		PATH arguments in all the various AC_ARG_WITH macro calls.  
	  Added main/*.h to header-checks, was strangely missing before.  


2006-02-23	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-16-maintainence-04:
	  More autoconf macro checks for libraries, and automatic
		accumulation of CPPFLAGS, LDFLAGS.  (Should use AC_SUBST)


	* HACKT-00-01-04-main-00-77-16-maintainence-03:
	  AC_DEFUN'd more attribute macros and lex/yacc checking.  
	  configure.ac: is reasonably clean (maintainable) now.  


2006-02-22	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-16-maintainence-02:
	  Round two of defining autoconf checks in config/*.m4.
		This already feels much more organized and manageable.  


	* HACKT-00-01-04-main-00-77-16-maintainence-01:
	  Organizing the clutter of autoconf macros into the config directory.
	  This first revision is just a start for demonstration.  


2006-02-20	David Fang	<fangism@users.sourceforge.net>

	* HACKT-00-01-04-main-00-77-12-merged-aggregate-01-10:
	  Branch merge.


	* HACKT-00-01-04-main-00-77-11:

2005-08-14	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-55-footprint-01-05-canonical-03:

2005-07-24	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-52:

		latex vs. pdflatex to conditionally clobber auxiliary files!


2005-07-20	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-49-maintainence-01:
	  Project-wide cleaning of Makefile.am and cvsignore files.

	* ARTXX-00-01-04-main-00-35:
	  From now on, #include files should refer to full relative path,

	* ARTXX-00-01-04-main-00-24:
	  From now on, revision details should be written to

	  Another -1000 LOC!

	* -inststmt-09: gcc4 standard compliance patch, 
	  template-related name fixes.  Compiles and passes all tests.  
	  Ready to commit to trunk.  


2005-03-10	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-18-inststmt-04-merged-collection-03:
	  Merged revisions from -collection child branch (-03).

	* -inststmt-05:
	  Updating the way instantiation statements are unrolled
	  (tested on pint and pbool inst_stmts, which currently use
	  the instantiation statement class template.  
	  The work for resolving the range of instantiation is pushed
	  to the instantiation_statement_base, which owns the
	  indices (range_expr_list) pointer.  
	  value_collection::instantiate_indices now takes const_range_list&.
	  Added range_expr_list::unroll_resolve (pure virt.).
	  Added const unroll_context& argument to 
		class_traits<Tag>::instantiation_statement_type_ref_base::
			unroll_type_check().  

	* -inststmt-06:
	  Applied same changes to proc,chan,data types, but haven't
	  applied instantiation_statement template to them yet.

	* ARTXX-00-01-04-main-00-18-inststmt-03-collection-03:
	  Cleaned up conditional code with USE_VALUE_COLLECTION_TEMPLATE.  
	  Resulting in 2000 fewer LOC.  :)

	* ARTXX-00-01-04-main-00-18-inststmt-03-collection-02-merged-expr-05:
	  Merged in revisions from -expr child branch (through -05).

	* ARTXX-00-01-04-main-00-18-inststmt-03-collection-01-expr-04:
	  Fixed problem with error message, mis-carried return statement
	  turned into bug during copying.  Doh.  
	  Use of value_reference template is now enabled.  
	  After cleanup, we can retire this baby branch...

	* -expr-05:
	  Cleaned up USE_VALUE_REFERENCE_TEMPLATE and 
	  USE_CONST_COLLECTION_TEMPLATE.  Ready to merge to parent.  


2005-03-08	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-18-inststmt-03-collection-01-expr-01:
	  We need to port many expressions classes to follow consistent
	  templates, this has been punted for way too long. 
	  Need to rename some methods to conform to standard interface.  

	* -expr-02:
	  Ported pint_const_collection to const_collection_template.
	  Renamed {may,must}_be_equivalent method functions of many
	  pint and pbool class derivatives.  

	* -expr-03:
	  Added code for porting pint/pbool_instance_reference to
	  value_reference template class, but kept it disabled for this
	  revision with USE_VALUE_REFERENCE_TEMPLATE set to 0.  
	  (Enabling it yielded different error messages in the param test
	  directory, and haven't figured out why... will need stacktrace?)
	  Removed (comment) unnecessary
	  pint_instance_reference::unroll_resolve_index method.  

	* ARTXX-00-01-04-main-00-18-inststmt-03-collection-01:
	  Porting parameter instance collections to use new value_collection
	  template, similar to instance_collection class template.  
	  Updated "art_built_ins.cc" to follow more procedural
	  default parameter initialization.  
	  More of class_traits<{pint,pbool}_tag> fleshed out, giving them
	  some parameter-specific traits.  
	  Next: param_instance_reference upgrading.  


2005-03-07	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-18-inststmt-03:
	  More details on class_traits<>::instantiation_statement_type_ref_ptr
	  interface, also provided a default empty class implementation.  
	  Need to rework instantiation statement framework: which methods
	  are responsible for type-checking, index/range-resolving, 
	  sparse-instance populating, etc...
	  but _after_ fixing interface for range_expr_lists.

	* Happy Birthday to ART++!
	  (Wait, I've spent a year on this!?)


2005-03-06	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-18-inststmt-02:
	  Ported pbool and pint_instantiation_statement to using
	  new instantiation_statement template, everything works still.  
	  Leveraging specialization of a parent type-reference base
	  through class_traits, so that built-in types need not
	  include unnecessary pointers (optimization).  
	  Will continue with data, channel, and process inst-stmts.  


2005-03-06	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-18-inststmt-01:
	  Spawned branch for reworking instantiation statement classes
	  into easier-to-maintain templates, using class_traits<Tag>.
	  This first revision just renamed instantiation_statement to
	  instantiation_statement_base to make way for the template name.  

	* ARTXX-00-01-04-main-00-18:
	  Major cleanup.
	  Stripped archaic debugging files "art_debug.h"
		  "art_parser_debug.h" "art_switches.h".
	  Removed any debug macros that were derived from those files.  
	  Split some more AST header files to reduce inclusion of
		unnecesary header files, by recursion.


2005-03-05	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-17-merged-chunkmap-03:
	  Merged revisions from -chunkmap child branch (through -03).  

	* ARTXX-00-01-04-main-00-16-chunkmap-01:
	  This branch is for developing custom allocators.  
	  Draft of working chunk_map_pool, tested.  
	  Rule for allocators: they are NOT responsible for calling
	  construct and destroy, only allocating.  
	  Need to revisit list_vector_pool's use.  
	  No more lazy- or eager- destruction business...
	  Later revision will add macros to override new and delete
	  using the chunk_map_pool.  

	* -chunkmap-02:
	  Realized mistake in list_vector_pool implementation.
	  Even overloaded new/delete operators implicitly call
	  ctors and dtors on the relevant pointers, thus rendering
	  eager/lazy destruction somewhat irrelevant -- always destroyed
	  afer delete.  To compensate, re-construct elements pointed
	  in the free-list before destruction of the pool.  
	  Cleaned up files a bit.  Will apply these concepts to chunk_map_pool.

	* -chunkmap-03:
	  Wrote CHUNK_MAP_POOL declaration and definition macros, 
	  in the style ripped from list_vector_pool.  
	  Updated LIST_VECTOR_POOL_DEFAULT_STATIC_DECLARATIONS macro name.  
	  Corrected little pointer arithmetic bug in 
	  typeless_memory_chunk::__deallocate.
	  Ported ART::parser::token_char to using chunk_map_pool now.  
	  Everything still works.  Going to check with gcc4 before
	  marking ready to merge to trunk... still good, no new issues.  


2005-03-03	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-16-merged-collect-02:
	  Merged in revisions from -collection child branch up to 
	  subrevision -02.  

	* ARTXX-00-01-04-main-00-15-collect-01:
	  This branch is intended really a continuation of where the last
	  -13-persistent branch left off.  This focuses on improvements
	  to the persistent object manager.  
	  Major improvements in this revision:
	  Added mechanism to mark and classify visits through
	  persistent_object_manager::read_pointer<>().
	  This allows the manager to verify the status of ownership of each
	  reconstructed pointer during load_objects().  
	  Any object that doesn't meet the "claimed" criterion may be
	  deleted by the reconstruction_table_entry when it expires
	  (unless otherwise flagged).  
	  This makes load_objects() exception-safe!  
	  Little note: needed "special handling" of built-in-datatype-def
	  pointers faked as user-defined-datatypes,
		see "art_object_type_ref.cc"
	  Minor improvements include cleanup of other source and header files.  
	  To do: upgrade the reconstruction_table to list_vector to 
	  avoid bulk copy-construction on a push back operation.  

	* -collect-02:
	  Upgraded persistent_object_manager's reconstruction_table
	  to util::list_vector<reconstruction_table_entry>.  
	  NEVERMORE will the entire array of entries be reallocated to 
	  new locations upon push_back()!  
	  Accesses to the array are now O(log(N/C)) where N is the 
	  total size, and C is the chunk-size (because of internal map).  


2005-03-03	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-15:
	  Cleaned up commented out code in #if HAVE_PERSISTENT_CONSTRUCT_EMPTY

	* ARTXX-00-01-04-main-00-14-merged-persistent-02:
	  Some file tags were screwed up in CVS, so merging early back to
	  main trunk first (for coherence sake), then splitting off again.  

	* ARTXX-00-01-04-main-00-13-persistent-02:
	  (With old code kept commented out)
	  Replaced bare construct_empty function pointers with
	  nullary constructor functors, more generalizable.
	  (Tradeoff: virtual dispatch overhead.)
	  Almost every file in src/Object affected.  
		+ util: improvements to new_functor, and nullary_function
			templates including compile-time switch
			between virtual and non-virtual parent.  
		+ new_functor is always derived from virtual base, 
			nullary_function_virtual<T*>.
	  Some later revision will have to clean-up code as always.  


2005-03-02	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-13-persistent-01:
	  Some big plans for this line of development.  
	  This revision just added a few utility classes for turning
	  constructor calls into functors (with virtual function).  
	  Some persistence files were touched up for clean up.  
	  Plans include: re-doing the persistent reconstruction 
		framework to use constructor functors, rather than
		raw pointers to static construct_empty(int).
		+ Instead of overloading one type-key entry for the 
		  table of reconstructors, we'll upgrade to a table
		  of vectors of constructor functors, where the vector
		  is indexed by the auxiliary constructor argument, 
		  (instead of passing it to construct empty).  
		+ Will phase out the construct_empty pattern.  
		+ re-do collect_transient_info so that the object
		  manager will handle visit once traversal.  
		+ Transient object registration will be done through
		  passing pointer-objects so that each visit may be flagged
		  with the type of pointer used to visit.  
		  (But we also don't want to burden the caller with 
		  knowing the type-key, that should be automatic still.)
		+ Handle exceptions during load object, and ensure 
		  proper methodical clean-up of allocated but un-touched
		  memory upon exception in load_objects().  
		  This will require some finesse.  


2005-03-01	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-13:
	  So I forgot to include the new try_lex_catch.awk script 
	  last revision, my bad!  
	  While I was at it, straightened out some symbol namespaces
	  and linkage with the parser.  

	* ARTXX-00-01-04-main-00-12:
	  Made lexer/parser more exception-safe by throwing exceptions
	  and proprely freeing memory when caught.  
	  A few basic tests have been added to the lexer that demonstrate
	  that no memory leaks occur with this mechanism in place.  
	  Updated {yacc,bison}-union-type.awk to do a litle more 
	  array-bounds checking on union-lookup.  
	  To do eventually: make persistent object-loader exception safe.
	  This will be much more difficult because of difficult
	  guarantee that each object in the table is visited only once.  
	  May require a destructor-like method in each class that
	  registers each visit with the persistent object manager.  

	* ARTXX-00-01-04-main-00-11-merged-what-01:
	  Merged insignificant revisions from -10-what-01.  

	* ARTXX-00-01-04-main-00-10-what-01:
	  This branch attempting to work around some multiple definition
	  linking issues with implicitly instantiated symbols, 
	  particularly from util::what.  This issue only arises with
	  gcc-4.0 with odcctools' ld linker.  
	  This is going to be nearly impossible to fix in the near future, 
	  but nothing is broken, I'm only easily irritated by warnings.  
	  Will revisit this issue another day.  


2005-02-28	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-10-merged-bool-06:
	  Merged revisions from -bool branch (-06), 
	  improving semantic clarity of boolean values in the program.  

	* ARTXX-00-01-04-main-00-09:
	  Support for gcc-3.2 (ix86-linux) dropped.  It *BOMBS* completely.
	  Wrote some notes in the source on where and why things die.
	  Don't even bother trying to compile util/test/integer_traits_test.
	  (If you try, don't say I didn't warn you.)
	  The art* executables all compile with a little help from this patch,
	  but all executables die a horrible abort-trap death.
	  (Something is horked with the global static initialization 
	  and destruction, I believe.)
	  (It's a fact of compiler-life: code dies, life goes on.)

	* ARTXX-00-01-04-main-00-08-bool-03:
	  This revision has nothing to do with bools, 
	  but are targeted back to the main trunk anyhow.  
		+ Makefile notes on various CFLAGS, for future
		  super-anal-retentiveness.  
		+ Notes on where gcc4 gets multiple definition warning
		  with ranlib.  
		+ A few standard-conforming tweaks.  
		+ Better namespace injection workaround "pointer_manipluator.h"

	* -bool-04:
	  Upgraded bool return values for methods in definition classes, 
	  some expression classes, instantiation statements, 
	  instance collections.  

	* -bool-05:
	  Upgraded more bool return values in expression methods and
	  param value instance collection methods.  
	  Actually caught an old (wrong error message) bug in the process!

	* -bool-06:
	  Final revisions upgrading bools.
	  Upgraded some class methods in context, definitions, 
	  param assignments, connections, instance_references, namespace.
	  This is ready to merge to trunk.  


2005-02-27	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-08-bool-01:
	  This branch is for changing ALL diagnostic functions to 
	  return a "good_bool" or "bad_bool" two new bool types defined
	  in "util/boolean_types.h".  This will help keep the meaning of 
	  return values clear and self-documenting.  
	  Initially testing on a few classes at a time.  

	* -bool-02: boolean upgrades to expression assignments.  

	* ARTXX-00-01-04-main-00-08:
	  Passes on all tested platforms and compilers:
	  {gcc-3.3, 3.4, 4.0} x {FreeBSD, linux, darwin}
	  Some ranlib warnings about multiple definitions 
	  (related to util::what) using odcctools' ld with g++-4.0.  
	  Will try to appease it in next revisions.  
	  Will spend some revisions improving code that will benefit
	  development along all directions before branching again.  

	* ARTXX-00-01-04-main-00-07-merged-object-01-18:
	  The great merge.
	  Merged huge revisions from object-01 branch to mainline.  
	  Tested on powerpc-apple-darwin, with gcc-3.3.  
	  Will also check with gcc-4.0 (pre- 20050130)
	  FreeBSD gcc-3.4, and ix86-linux.  

	* ARTXX-00-01-04-main-00-06-merged-parser-01-05:
	  Merged moderate revisions to parser and front-end into mainline.  

	* ARTXX-00-01-04-main-00-05-merged-docs-00-01:
	  Merged in tiny revisions to documentation from last series
	  into mainline.  

	* ARTXX-00-01-04-main-00-04-parser-01-05:
	  Slight reorganization of some util library headers.  
	  Added placeholder code for chunk_map_pool.  
	  Definition is pending a merge to the main trunk, 
	  will depend on maplikeset, defined in -object-01 branch.  
	  It's time for convergence!

	* ARTXX-00-01-04-main-00-04-object-01-17:
	  Successfully worked around defects in prerelease of gcc4 (20050130).  
	  Code compiles and passes all tests, with some archival warnings
	  from odcctools' ld/ranlib.  (powerpc-darwin only)
	  Workarounds included additional using declaration in
	  util/memory/pointer_manipulator.h to prevent friend class
	  forward declaration name-injection.  
	  Explicit template typedef typename was added to 
	  art_object_instance_alias.h and art_object_instance_collection.h.
	  None of these modifications cause any regressions with gcc-3.3.
	  Added some missing *_instance method definitions to satisfy
	  g++-4.0's ld.  

	* -object-01-18:
	  Updated DevelopmentPlan.dot.


2005-02-26	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-15-merged-alias-12:
	  Merged in tons of revisions from the alias child branch.  
	  Hallelujah!  *Basic* alias connections work.  

	* -object-01-16:
	  Added DevelopmentPlan.dot, which makes a .ps.  
	  No more relying on the white-board in my office.  

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-10-merged-instance-13:
	  Merged all revisions from -09-instance child branch (rev -13)
	  in this branch, very critical for progress.  

	* -alias-11: "breakthrough"
	  The moment we've been waiting for...
	  First successful unrolling of connections, with persistence!
	  Tested one case with scalars, and one complicated case 
	  with multidimensional slices, and they pass!
	  Currently, connection-equivalence type-checking is not yet
	  implemented, that will have to wait until the -object-02 phase.  

		Other minor changes:
		+ cleaned up packed_array*, removing packed_array_base.

	* -alias-12:
	  Added more tests for alias connections in connect directory.  
	  Many unroll tests disabled because required features aren't
	  implemented yet, such as port connections and member instance
	  references.  (Member instance references will require
	  type/definition layout first.)  
	  This branch is now ready to merge to parent.  


2005-02-25	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-09-instance-10:
	  Ported all int-related instance classes (aliases, info, collection, 
	  arrays) using the instance_collection template family.  
	  This added ring-connection data to the binary, which resulted
	  in updating tests because of increased object binary sizes.  
	  New member of class_traits: tag_name (const char[]).
	  90% of art_object_instance_{int,bool}.{h,cc} are commented out now.
	  Will perform massive cleanup after applying instance collection
	  template to remaining types: enum, struct, channel, process.

	* -instance-11:
	  Ported and upgraded enum to instance_collection template, 
	  same story as before.  They now have alias connections.  
	  Sweet, that was easy... structs, you're next.

	* -instance-12:
	  Ported datastruct, channel and process collections using 
	  instance_collection template in one fell swoop.  
	  Added a physical_instance_collection type between
	  instance_collection_base and datatype/channel/process collections.  
	  Wrote appropriate functor specializations for them.  
	  Updated interface of collection_persistence to use 
	  static function calls: collect, write, load. 
	  Process and channels (aliases) are now initially connected
	  to themselves.  
	  This branch is nearly mature,  next revision will be 
	  massive cleanup before merging to parent.  

	* -instance-13:
	  Ahhhh... code is 7000 lines lighter after the removal
	  of blatantly replicated code in the old instance_collection
	  implementations.  This branch is ready to merge to parent.  


2005-02-24	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-parser-01-03:
	  art++-parse.yy: deleted uses of *_append *_wrap macros, 
	  in preparation for substituting code with new node_list.

	* -parser-01-03:
	  Some clean-up of macros, added node_position class, 
	  wrote new node_list class.  

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-09-instance-05:
	  Chose bool_instance_alias_info as the first guinea pig class
	  to use instance_alias_info class template, 
	  based on class_traits<Tag>.  
	  Nothing blew up, all tests still intact.

	* -instance-06:
	  Major name clean-up and substitution to reduce ambiguity
	  and provide template-typedef-like naming interface
	  with class_traits for dimension-specific classes.  

	* -instance-07:
	  Ported bool_instance_alias_info, bool_instance_alias_base, 
	  and bool_instance_alias<D> to class_traits template version.  
	  All test still intact!  Next: porting instance_collections.

	* -instance-08:
	  Converted bool_instance_collection and arrays over using
	  template instance_collection.  Nothing died, but code is 
	  messy with conditionals...
	  To do: define functors for type-specific variations
	  in methods... may have to make them 'friendly'.  

	* -instance-09:
	  Added instance_collection functor prototypes for 
	  collection parameter persistence, type-committing.  
	  So far, only specialized for bool_tag, others will follow in time.  


2005-02-23	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-parser-01-02:
	  Started to re-organize parser code base some.
	  check_build is no longer in ART::parser_node, because we only ever
	  call it from main through root_body.  
	  Later, each sub-class may have its own prototype, 
	  especially for return types -- makes much more sense
	  and waill actually make some use of the return value, which 
	  is currently ignored in most cases.  
	  Some lexer structs moved into the ART::lexer namespace.
	  Supplied "Fang, write me!" to many unimplemented 
	  check_build()'s temporarily, causing a few updates to
	  test suite expected outputs.  
	  Coming soon: replacement code for node_list class template.

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-09-instance-01:
	  New branch for the purpose of making the instance_collection
	  class framework consistent.  
	  This revision introduces classification tag which control the 
	  infrastructure of template class patterns with a set of
	  traits-class specializations.  
	  So far, we applied this to member_instance_references as a 
	  test case, and everything is hunky-dory.  

	* -instance-02:
	  Converted instance_reference to use class_traits<Tag>.
	  Next: alias_connections, then ... instance collections, 
	  the final frontier!

	* -instance-03:
	  alias_connections converted to class_traits, muahahaha...
	  Code needs some serious clean-up before proceeding.  

	* -instance-04:
	  Cleaned-up, no more conditionals on SUBTYPE_ALIAS_CONNECTION
	  and USE_CLASSIFICATION_TAGS.  


2005-02-22	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-parser-01-01:
	  New branch started off of the trunk, dedicated to improving the
	  front-end lexer/parser.  
	  In this revision, we sliced and diced the AST/ header files into
	  more manageable units, resulting in noticeably faster 
	  compile-times, and even smaller binaries.  
	  See what a little organization can do?
	  Later revisions will re-work the parser, especially the 
	  node_list aspect, eliminating non-essential terminals.  


2005-02-21	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-09:
	  Fixed multikey_assoc::is_compact(), adding necessary, 
	  implicit conversion to key type in {int,bool}_instance_alias.  
	  Really sick and tired of maintaining copies of code for each
	  physical instance collection type... it's time to employ
	  templates with policy functors... (sub-branch).

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-08:
	  Initial testing of instance unrolling, without connections, 
	  just for int_instance_collection, our guinea pig.  
	  Placeholder code pasted into other instance collections, 
	  but marked as empty for now.  

		+ Updated packed_array[_generic] template signature to 
		  include type for index, so it's not hard-coded to size_t.  

		+ Fixed bug in multikey_assoc::is_compact()'s return value
		  for the case where D == 1.
		  There may be another bug for D != 1, related to 
		  index_extremities, look for "WRONG" in "multikey_assoc.tcc".

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-07:
	  Added draft of code for alias_connection unrolling, untested.  
	  Added draft code for reference unrolling, packing aliases
	  into packed_array_generics.  
	  Added tons of methods for unroll-time expression resolution, 
	  many of which seem redundantly redundant -- clean later.  

		+ unroll_aliases method only appears in int_instance_collection
		  for now.

		+ Some minor interface improvements to packed_array_generic, 
		  and multikey_generator_generic.

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-06-merged-instref-02:
	  Merged -instref-02 revisions.

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-05-instref-01:
	  Replaced copy-pasted *_instance_reference with template
	  class definition instance_reference<Collection,Parent>, 
	  which makes this code so much more maintainable!
	  Next revision: clean-up.

	+ -instref-02: cleaned up, ready to merge to parent branch.

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-05-merged-persistent-04:
	  Merged -persistent-04 branch revisions into this branch.

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-04-persistent-04:
	  Substituted direct use of TYPE_KEY macros with
	  persistent_traits<...>::type_key for less copying, 
	  better maintainability.  
	  This revision is clean and ready to merge with parent branch.


2005-02-19	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-04-persistent-02-member-01:
	  Child branch created for the sake of revising the 
	  member_instance_reference system.  
	  Testing to see if member_instance_reference_base
	  really requires simple_instance_reference as the base type, 
	  should really be generic.
	  (a few connect tests will still die until announced otherwise)

	+ -member-02:
	  Changed base type of member_instance_reference_base to generic
	  instance_reference_base.  Later, the base type shouldn't be allowed
	  to be complex-aggregate, so perhaps deriving from nothing 
	  (instead of instance_reference_base) is the correct thing to do.  

	+ -member-03:
	  Replaced all member_instance_references with template
	  versions, extended datatypes members into subtype-specific
	  versions.  ALL tests pass in this revision!
	  This revision is littered with commented out code, next revision
	  must clean up.  

	+ -member-04: cleaned-up, ready to merge to parent branch.

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-04-persistent-03-merged-member-04:
	  Merged -member-04 child branch.


2005-02-18	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-04-persistent-01:
	  Subtype template classes for alias_connection s are enabled, 
	  everything compiles, but there is some difficulty with 
	  persistent type registration: the hash_key's are not retrieved
	  properly by calls to static persistent_traits<T>::get_hash_key.
	  Solution: we need proper specialization of persistent_traits, 
	  which currently isn't done because type-keys are only registered
	  dynamically by static objects, hence specialized definitions
	  do not exist.  This branch will remedy this by using specialization
	  and dynamic registration (for unique ID).  
	  This initial revision compiles, but some tests will die while
	  modifications are in transient state.  

	+ -persistent-02:
	  Overhauled persistent type registration as promised.  
	  Compiles, runs most tests, some unexpected deaths in 
	  tests/parser/connect.  Must sleep first...
	  Deaths related to datatype_member_instance_references.


2005-02-18	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-04:
	  Draft of template code for alias_connection.  
	  Need to write instance_reference_base::make_alias_connection
	  before enabling new class heirarchy (conditional now).
	  Happened to do some header clean-up in this revision too.  


2005-02-17	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-13-alias-01:
	  New branch created for working on alias_connections.  
	  May require some serious reworking and sub-typing.  
	  Issue is what the interface for unrolled instance connection
	  should be.  

	+ -alias-02:
	  Cleaned up some of object class heirarchy, having object as
	  super-uber-parent is totally unnecessary in most cases.  
	  Preparing to perform some major surgery on instance_reference
	  and alias_connection class sub-heirarchy for connections.  

	+ -alias-03:
	  Renamed some classes, conditional code in-place for
	  extending aliases_connection_base class heirarchy.  
	  Some NOTES on proposed parse-context improvement in the future.  
	  Everything still stable, the calm before the storm...

	* ARTXX-00-01-04-main-00-04-object-01-13:
	  Prelimiary testing of saving and restoring bool instance aliases, 
	  where there are no actual connections.  So far so good.
	  Some minor updates to instance dumping.  
	  Tests were also updated because of expansion in bool
	  instance object binary size.  


2005-02-16	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-12:
	  Wrote draft of code to save and restore bool aliases, 
	  untested and disabled, so all tests still pass.  
	  Will enable and test in next revision.  

	* ARTXX-00-01-04-main-00-04-object-01-11-merged-gcc4-02:
	  Merged tiny revisions from the -09-gcc child branch, 
	  through rev -02.
	  These were micro-changes needed to make gcc-4.0 (prerelease)
	  happy, because of more standard-conforming behavior.  
	  That snapshot of gcc-4.0 (20050130) will not actually compile
	  succesfully due to a bug discovered, see 02-14 entry of ChangeLog.  

	* ARTXX-00-01-04-main-00-04-object-01-10-merged-multikey-09:
	  Merged all revisions from the -09-multikey child branch 
	  (through rev. -09)

	* ARTXX-00-01-04-main-00-04-object-01-09-multikey-07:
	  bool_instance_collections (scalar, array<D>) are once again
	  reconstructible *without* connections.  
	  (A lotta work to get nowhere!)
	  Next revision will massively clean-up before porting over the 
	  overall changes with bool collections to int<W> collections.
	  Then we'll attempt to reconstruct aliases... ooooh...

	+ -multikey-08:
	  Massively cleaned up, as promised.
	  Affected: multikey_map-related files, art_object_instance_bool.*

	+ -multikey-09:
	  int_instance_collections are reconstructible once again.  
	  No aliases reconstructed yet.  
	  Many test output updated because binary objects have changed size.
	  All tests pass, this snapshot is good enough to merge back to
	  the parent branch.  


2005-02-15	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-09-multikey-05:
	  Namespace clean-up only, replaced *_NAMESPACE in the util/
	  directory with 'util'.  

	+ -multikey-06:
	  IO_utils*: added value_writer and value_reader functors to
	  facilitate partial specializations with template classes.  
	  Defaults to using plain-old write_value and read_value.  
	  Skeletal implementations of bool alias persistence and 
	  reconstruction.  
	  bool_instance_alias<D> is now derived from 
	  multikey_set_element_derived!  (except when D == 0)
	  Thus, bool_array<D> may directly use multikey_set<element_type>.
	  This revision compiles, same as before, but not all tests pass
	  because code is in transient state.  


2005-02-14	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-09-multikey-03:
	  Designed "derived" versions of maplikeset_element and
	  multikey_set_element.  Functionally, they are the same as their
	  non-derived counterparts, but their implementations facilitate
	  composition of features such as ring_node-connectivity.  
	  These have been tested individually in the util/test directory.  
	  Next revision will test the composability on
	  "art_object_instance_bool.*".  

	+ -multikey-04:
	  Now using node_ring_derived for alias base.
	  Now using multikey_set_element_derived in bool_array<D>.
	  Trying replacing bool_instance_alias_base derived definition
	  with typedef to ring_node_derived<bool_instance_alias_info>.
	  Everything compiles, nothing dies, tests don't pass still
	  because alias persistence hasn't been implemented yet.  
	  Some updating in maplikeset.h, multikey_assoc.h now uses
	  _Select1st, _Select2nd functors to allow specialization
	  of key-value accessors.  (Needs clean-up.)

	* ARTXX-0-01-04-main-00-04-object-01-09-gcc:
	  Branch created for the sake of isolating an ICE bug with
	  gcc-4.0 prerelease 20050130.  

	+ ICE-trigger example reduced to about 30 lines in "gcc4death.cc"
	  Submitted to gcc bugzilla database as report # 19948.  


2005-02-13	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-09-multikey-02:
	  Enabled instance_alias persistence of parameters (pint, pbool)
	  because they contain no pointers.  
	  multikey_map.tcc: using {write,read}_value with the key 
	  of the key-value pair.  

	+ Complication: desire the connective properties of ring_node
	  and the key-aware properties of maplikeset_element
	  (manifested as multikey_set_element), but creating such
	  a result is highly non-trivial with the current data structure
	  library.  

	+ Added a variation of ring_node call ring_node_derived, which
	  extends a base type, by making it ring-node-connected to
	  its own type.  This will be required for use with 
	  maplikeset_element, because one cannot compound two container-like
	  adapters to make a super-type with the properties of both parents.  
	  Testing passed easily... too easily.  

	+ Drafted an implementation of bool_instance_alias_info
	  and bool_instance_alias_base, which will be adapted in the
	  next revision to use ring_node_derived.  

	+ Much clean-up of art_object_instance_bool.h.

	* ARTXX-00-01-04-main-00-04-object-01-09-multikey-01:
	  In this child branch, I'm play-testing the development of 
	  using multikey_set for instance aliases, and ways of 
	  reconstructing connections through object persistence.  
	  This snapshot compiles and runs, but many tests will not pass
	  because instance collection persistence has been disabled.  
	  Working on the persistence of aliases...


2005-02-08	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-08-merged-set-16:
	  Merged all revisions from -set child branch.  No issues.  

	* ARTXX-00-01-04-main-00-04-object-01-07-collection-00-trans-00:
	  Temporary sibling branch for changes that have to wait until
	  after -set branch is merged.  

	* ARTXX-00-01-04-main-00-04-object-01-07-set-15:
	  Once again stable.  Introduced maplikeset interface to 
	  adapt a set to have a map-like interface, where key components
	  of set::value_type may be passed to method functions.  
	  Stuck this into multikey_set and multikey_set_element, 
	  and it works like magic, AFAICT.  
	  Code is in real desparate need of housekeeping... next rev.

	+ -set16:
	  Cleaned up and removed excess commented code.  
	  Reverted some changes to multikey_assoc back to the way they
	  were before the multikey_set fiasco.  
	  Code is trim and functional.  Time to move on.  


2005-02-07	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-07-set-12:
	+ "ring_node.h": eliminated need for const_cast of second
	  pointer in iterator construction by const-ifying 
	  the second pointer member, which is never dereferenced anyways.  

	+ -set-13: "multikey_assoc*": multidimensional associative 
	  container adapter.  Factored out multidimensional facilities
	  of multikey_map into multikey_assoc template wrapper.  
	  Much removed code in commends in this snapshot.  

	+ -set-14-trans-00: "multikey_set*" family added (1st draft), 
	  *almost* entirely working, just needed to add initial files
	  to checkpoint first revision.  
	  This is a *transient* snapshot, and will compile, but the newly
	  added test (multikey_set_test) does not run correctly yet.  
	  Many adaptations have been made to the base multikey_assoc, 
	  without disturbing the functionality of multikey_maps.  
	  Future plans for major improvement of code maintainability:
	  Make a set adapter to give map-like key-value interface to 
	  std::set, since we find ourselves working around basic
	  fundamental differences.  


2005-02-06	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-07-set-07:
	  Obliterated multikey_base, multikey_map_base.
	  (Actually, just #if 0'd all referenceds to them)
	  A few regression tests were updated with more accurate
	  error reporting in test/parser/param.  

	+ -set-08:
	  Expurgated any and all references to the virtual base types
	  involving multikey and multikey_map.  

	+ -set-09:
	  Factored out multikey implementation into seperate struct, 
	  for the sake of specializing the <1> case.  
	  Implements standard sequence/iterator interface.
	  Replaced direct references to indices[] array with iterators.  
	  Removed (comment) specialization of multikey_map using qmap
	  as the implementation type, no longer needed.  

	+ -set-10:
	  Eliminated virtual base classes (in comments, flagged out):
		  base_multidimensional_qmap
		  base_multidimensional_sparse_set
	  Internalized/privatized implementation of 
	  simple_instance_reference::mset_base, defining as a module-local
	  virtual base class in "art_object_inst_ref.cc".
	  In general, we prefer this pattern of "let the user virtualize"
	  the various dimension-specific data structures.  
	  We provide a uniform functional interface to make this easy.  

	+ -set-11:
	  Cleaned out commented and flagged out blocks of code
	  removed from revision -set-10.


2005-02-05	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-07-set-01:
	  Many util library improvements.

	+ "pointer_traits" completely re-done.
	  Individualized traits, for better orthogonal design.  
	  Instantiating pointer_traits for the purpose of using one trait
	  would try result in instantiating for all traits, some of 
	  which were not applicable.  
	  Leveraged partial specializations in various pointer classes.  

	+ "const_assoc_query" an implementation-independent wrapper
	  for maps to overload the lookup [] operator.  
	  (This would've saved hundreds of lines of useless wrapping
	  in qmap.* and hash_qmap.*)

	+ "null_construct.h" guarantees initial values for constructed
	  objects, especially pointers, which default to junk.  
	  Useful for const-query returning of null pointers when 
	  something is not found.  

	+ "hash_qmap.*" wiped verbose definition, and replaced with
	  const_assoc_query wrapper.  So simple!  Legacy code 
	  in the declaration and definitions files is block commented out.  
	  Next revision will alter qmap, and add qset.  

	+ -set-02: qmap now derived from const_assoc_query<std:map<...> >

	+ -set-03: consistency patch
	  Changed multikey_base<pint_value_type> to
	  ART::entity::multikey_index_type as defined in "art_object_index.h"
	  Preparing to obliterate multikey_base...
	  and create multikey associative interface...
	  multikey_base has been obsoleted by the introduction of 
	  multikey_generic.  

	+ -set-04: slowly phasing out multikey_base.
	  Minor extensions to multikey interface, ablility to convert from
	  generic type to dimension-specific with assertion check on size.  
	  Replaced definition of multikey_index_type with multikey_generic.  
	  Goal: no more virtual function calls from multikey_base.  
	  To do: continue similar changes with "unroll_index_type".
	  Possibly specialize multikey<1> as plain value instead of [1].

	+ -set-05: no more references to multikey_base remaining.
	  Replaced unroll_index_type with multikey_index_type, 
	  both are multikey_generic<pint_value_type>.

	+ -set-06: changed signature of dereference functor
	  to take a generic class argument, and using pointer_traits
	  (internal_reference<T>::type).
	  Relocated "dereference_t" and hellper to "dereference.h".
	  Updated all affected source files.  


2005-02-04	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-07-set:
	  Branch dedicated to developing multikey_set structure.  
	  Consider re-doing all of multikey_map family:
	  create a qtree, underlying base type to qmap, qset.
	  Or a multikey-tree, with new multikey methods?


2005-02-03	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-06:
	  Worked on new data structure: ring_node!
	  Is a singly-circularly linked list that implements the 
	  standard container and iterator interfaces, so one may use any 
	  STL algorithm on begin() and end(), or intermediate iterators.  
	  Maintains circular linkage (and uniqueness) invariant.
	  Nodes maintain circular structure even when members of ring
	  are destroyed, thus no additional memory management burden 
	  on the user.  Note that such nodes are not truly copy-constructible;
	  when a node is copied, only the value object is copied, never
	  the forward pointer, which is in fact, always initialized to 
	  point to itself.  This is intended for use with connections
	  of instances and aliases... muahaha.
	  ring_node<instance_alias_containing_count_ptr_to_unique_instance>


2005-02-02	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-05:
	  Duplicate tag of -01-04-merged-unroll-00-03.

	* ARTXX-00-01-04-main-00-04-object-01-04-merged-unroll-00-03:
	  Merged in revisions from -unroll-00 sub-branch.

	* ARTXX-00-01-04-main-00-04-object-01-03-unroll-00-03:
	  Basic single process instance (alias) works.  
	  Made proc_instance_alias pseudo-persistent, 
	  never actually dynmically allocating through the object
	  manager, but still contains aliases to unique instances, 
	  which requires pointer management.  
	  Many tests updated.  
	  To do: be able to write / read collections of aliases.  

	* ARTXX-00-01-04-main-00-04-object-01-03-persistent-00-02:
	  Factored out "safety" code for persistent object management
	  out of all implementations of write_object, load_object.  
	  Gave write/load object references to iostream arguments.  
	  Gave persistent::load_object const persistent_object_manager& 
	  argument.
	  Cleaned out hash_map headers, moved to STL subdir, with forward
	  declaration file.  
	  Next, clean up the commented out code mess.  


2005-02-01	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-03-persistent-00-01:
	  Un-templated some non-essential method functions in
	  persistent_object_manager.tcc, relocated to .cc.  

	* ARTXX-00-01-04-main-00-04-object-01-03-persistent-00:
	  This branch created to introduce complete redo of 
	  persistent object management.  
	  Need to distinguish between heap/non-heap objects.  
	  Need to factor out object alignment and visit-once code. 


2005-01-31	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-docs-00:
	  New branch created for documentation of the ART++ language spec.  
	  (Not for doxygenating code comments.)

	* ARTXX-00-01-04-main-00-04-docs-00-01:
	  Defined template signature equivalence.  
	  Minor text tweaks.  
	  Consider using the listings.sty package, or converting
	  grammar into latex interpreter...


2005-01-30	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-02:
	  Major contributions in this release, improving template 
	  signature equivalence checking to be more precise.  

		+ Refined definition_base::dump to also report whether a 
		  definition object is merely declared or fully defined.  

		+ new: definition_base::lookup_template_formal_position()
		  to determine whether or not two formal parameter
		  instance references are equivalent (useful for comparison
		  during re-declarations).

		+ Changed template_formals_list implementation to vector, 
		  for constant-time formal position distance evaluation.  
		  (Can probably use vectors more for this reason...)

		+ instance_collection_base::is_template_formal():
		  now returns the 1-indexed position of the referenced
		  parameter instance collection, 0 if not found.  
		  formal_size_equivalence is updated to check for 
		  template parameter equivalence.  

		+ art_object_expr* (important):
		  Equivalence checking refined with pbool/pint/index/range
		  -specific versions to allow comparison by structural 
		  equivalence which is far more precise (but not perfect)
		  than what was in place before, which was over-conservative
		  w.r.t. constants and non-constants.  
		  Only the "must_be_equivalent" family of method functions
	 	  was improved.  
		  De-inlined some empty constructors and destructors.  

		+ Implemented part of process instance unrolling.  
		  Dumping-related functions improved.  
		  Added full set of checks in test/parser/process/.
		  Updated some old artc tests.  


2005-01-29	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04-object-01-01:
	  Implemented (enabled) unrolling for datatypes, added 
	  datatype_instance_collection::dump().
	  Refined error messages during unroll-time errors,
	  in pint/pbool_instance_collection, and updated tests.  
	  New tests in test/parser/array to test unroll-time error catching.  


2005-01-28	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-main-00-04:
	  These revisions merged and converged the revisions on the
	  -parser-00, -util-00, and -object-00 branches.  
	  No issues in merging, since their develop was mostly sequential.

	* ARTXX-00-01-04-main-00-04-object-01-00:
	  Implemented object de/serialization of enum data-type definitions
	  and instances.  Added bunch of tests in test/parser/datatype.
	  Updated definition_base::*_object_base to include the
	  'defined' member flag, which was forgotten before.  
	  Enum members are just treated as strings for binary persistence.  


2005-01-27	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-object-00-13:
	  Specialized read/write_value of pbool_instance, which contains
	  bit-fields, same story as bool -- 3 bools "compressed" to 1 char.  
	  (A few tests updated.)

	* ARTXX-00-01-04-object-00-12:
	  In util/IO_utils.{h,cc}, specialized write_value and read_value
	  with <bool> to use write/read_value <char> to ensure that
	  booleans are written out as one byte.  
	  (On darwin-gcc-3.3, passing bool defaulted to using a 4-byte int, 
	  on i686-linux-gcc-3.4, passing bool defaulted to using char.)
	  Gotta ensure platform independence!  

	* ARTXX-00-01-04-object-00-11-merged-fixutil-12:
	  Merged changes from the -fixutil sub-branch (up to -12)
	  into the main object branch.  

	* ARTXX-00-01-04-object-00-10-fixutil-12:
	  Test directory updated for new expected unrolled objects.
	  Differences to due to exclusion of built-in template int
	  definition argument.  (wasn't supposed to be there anyways)
	  Typedef_alias forgot to call scopespace base persistent
	  methods, resulting in fake leak.  Fixed.  
	  This revision should be sufficiently stable (verified on
	  darwin) to commit to the parent branch.  


2005-01-26	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-object-00-10-fixutil-10-merged-gcc-01:
	  Merged gcc-3.3 workaround into this parent branch.
	  Enhanced test scripts in src/util/test to be able to write
	  hook filters/scripts in case tests need more than the 
	  default filtering.  
	  This is intended to permit *slightly* different or even
	  non-deterministic behavior of various compilers, 
	  a common variation being LINK-ORDERING and global static
	  module initialization and destruction ordering.  
	  Fortunately, the revisions in this series have made 
	  the libraries extremely robust to "the ordering problem"
	  with explicit dependence macros.  
	  Slowly, we'll work our back out of "fixutil" to the parent branch.


2005-01-25	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-object-00-10-fixutil-09-gcc:
	  New quick branch spawned off to work around a gcc-3.3 bug.
	  (Not a problem in gcc-3.4)
	  Problem is related to friend function formal parameter misuse.
	  Problem can be demonstrated by
	  "util/test/friend_function_formal_bug.cc" in gcc-3.3.
	  Fixed, and merged back into -fixutil-10.

	* ARTXX-00-01-04-object-00-10-fixutil-08:
	  Been spending a few days fixing up a mysterious pseudo
	  memory leak (*GASP*).  The problem is cause by improper handling
	  of the built-in datatype definitions.  The whole definition
	  contents were still written out, which cause bad reconstruction.  
	  Data-type references have special handling for built-in types.
	  This snapshot has fixed it, but kept all the extraneous 
	  debugging options on.  After more testing, will gradually
	  recede the debugging level.  


2005-01-22	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-object-00-09:
	  Merged changes from -fixutil sub-branch, up to its -03 revision.
	  Net result: pool-allocate pint_const and pbool_const, 
	  but we made many side improvements along the way.

	* The lesson of the day is "function-local static."

	* ARTXX-00-01-04-object-00-08-fixutil:
	  Sub-branch created for introducing new improvements and fixes to
	  the util library.  
	  Modules affected: stacktrace, list_vector_pool, what.
	  list_vector_pool: introduced more robust version of macros
		for overriding new and delete operators
		-- new version is practically immune to adverse ordering
		of global static initialization, which is an issue when
		cross-module allocators are invoked; there must be a way
		to guarantee on-demand initialization:
			solution: function-local static instances!
		observation: consequence: out of conservativeness, 
			such static allocators will not be destroyed
			upon program termination IF the pool is referenced
			by multiple modules.  (won't be able to get leak 
			diagnostics from such pools)
		side note: tried and abandoned a reference-count scheme.
	what: updated interface and default macro definition
		now must call ::name() by function (no arg), 
		to match the typeinfo interface.  
		All definitions of name() store function-local static
		copies of the string, which are initialized upon 
		first entry to the function, so performance is still
		very efficient.
		This revision should be robust to all link-orderings
		so it is safe to reference ::name across modules.  
	stacktrace: replaced class static stack structures
		with function-local static objects.
		This makes stacktrace safe to use for debugging
		during static initialization and destruction.  
		+ New macros STACKTRACE_BRIEF and STACKTRACE_VERBOSE
		so user need not pass custom string everywhere.  
		+ Also added ostream check protection, in case ostream
		is destroyed before a trace is printed.  
	persistent_object_manager:
		you guessed it, replaced static members 
		(reconstruction_function_tbale) with 
		function-local static in the referencing static function.  


2005-01-21	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-objject-00-08:
	  New files: src/Object/art_object_extern_templates.{h,cc}
	  Tried playing around with separate template compilation for 
	  a few classes (multikey, packed_array).
	  Very little reduction in compilation time and final binary size.  
	  Only the smallest, most common classes were factored out.  
	  More signficant dimension-specific, content-type-specific
	  map classes cannot be efficiently collated.  
	  "With great specialization come great replication."


2005-01-20	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-object-00-04-cleanup:
	  Many typedef's updated, espcially those involving multikey.
	  Now everything is consistently maintained in a few definitions
	  in "art_object_index.h".  Other minor changes like renaming
	  parent to parent_type.  

	* ARTXX-00-01-04-object-00-05:
	  FINALLY wrote a prototype unroll system for the built-in 
	  datatypes.  Successfully tested basic int<32> instantiations.
	  Created placeholder class unroll_context for use in unrolling.  
	  Not all unroll methods have been adapted to use it yet.  
	  Expressions are unrolled into pint_const_collections
	  (pbool_const_collection to be created).  
	  Also updated util/multikey.* to provide reverse iterator interface.  

	* ARTXX-00-01-04-object-00-06:
	  Removed a TON of empty .stderr files from the repository, 
	  they are now automatically generated and cleaned by
	  the rules in the template makefile Make.test.

	* ARTXX-00-01-04-object-00-07:
	  test-Makefile's pain in the a**...
	  Updated .cvsignore generation to copy template (was linked before)
	  and include additional CLEANFILES, in all test subdirectories.  
	  Re-did Makefile.am's in all test subdirectories:
	  ARTC_TEST_SUBJECTS = $(ARTC_TEST_PASSES) $(ARTC_TEST_FAILURES)
	  This way, ARTC_TEST_FAILURES can be used for EXTRA_DIST, 
	  to avoid having to regenerate extraneous .stderr files.  
	  Perhaps auto-generating .cvsignore everywhere is a good idea...


2005-01-19	David Fang	<fangism@users.sourceforge.net>

	* New sub-branch: ARTXX-00-01-04-object-00-04-cleanup
	  Needed a makeover of typedefs, for sake of consistency
	  (e.g. long vs. int) and future ease of migration to templates.


2005-01-18	David Fang	<fangism@users.sourceforge.net>

	* ARTXX-00-01-04-object:
	  Added unroll tests for namespace subdirectory.  
	  Not exciting until example with int<>s are introduced.  

	* Created branch: ARTXX-00-01-04-util
	  This branch is for modifications to the utils library that
	  do not concern ART directly.  

	* Added util/numeric/integer_traits.h for compile-time evaluations.  
	  Some useless and fun code, like compile-time primality.  

	* Added util/ifthenelse.h for compile-time type and value selection.  

	* Merged patches to the utils from -object-00-03 to -util.


2005-01-17	David Fang	<fangism@users.sourceforge.net>

	* RELEASE 0.1.4
	  The root tag for this series is ARTXX-00-01-04.

	* Created branch: ARTXX-00-01-04-parser
	  This branch is intended for modifications to the front-end
	  lexer and parser.

	* Created branch: ARTXX-00-01-04-object
	  This branch is intended for updates to the type-checker, 
	  unroller, and object system of the compiler.  

	* ARTXX-00-01-04-parser:
	  Updated lexer: yy_current_buffer -> YY_CURRRENT_BUFFER
	  The macro's definition differs slightly between the current stable
	  version of flex (2.5.4) and the development version (2.5.31).
	  This maintains compatibility.  

	* Added LEX and YACC to configure.in with AC_ARG_VAR.

	* ARTXX-00-01-04-object:
	  Revised test *.sh check test-scripts.  
	  Introduced (preliminary) unrolling test, finally!  
	  Need to write {bool,int}_instance_collection::unroll().  

	* Added unroll tests to tests/parser/param directory.
	  Updated artobjunroll-expect.sh script to handle 
		  expected unroll errors.
	  Test suite is coming along...

	* Minor stuff:
	  In util/indent.cc: fixed disable_indent.
	  Updated dump() method to use better indentation in
		many Object class definitions.
	  artobjdump and artobjunroll handles exceptions from unrolling, 
		and also if input object file is empty.


2005-01-16	David Fang	<fangism@users.sourceforge.net>

	* FIXED: issue with __PRETTY_FUNCTION__ (linux-gcc only).
	  In src/Object/art_built_ins.cc, an innocent assert statement
	  (commented out) created an undefined reference to the 
	  __PRETTY_FUNCTION__ symbol, which is NEVER SUPPOSED TO EXIST, 
	  because it is a reserved MACRO internal to the compiler.
	  Removing the assertion statement suppressed the faulty symbol.  
	  Can you say, 'WTF'?


2005-01-15	David Fang	<fangism@users.sourceforge.net>

	* Added macros for convenient default use of list_vector_pool, 
	  in-class static member declarations and definitions.  

	* Added memory leak diagnostics to list_vector_pool:
	  basically size of free-list should be equal to peak usage, 
	  else there's a dangling pointer to an element in an allocated
	  region.  This is non-fatal (as long as the memory is not touched)
	  because deallocate() uses lazy destruction, i.e. only destroys
	  upon allocation off of the free-list.  

	* Fixed premature memory deallocation of assignment and 
	  connection objects in context::add_assignment and ::add_connection, 
	  in "art_context.cc".

	* Updated src/util/test/test-expect.sh:
	  uses test/address_filter.sed to filter out addresses which will
	  vary on every system.  

	* PROBLEM (solved): 
	  Upon exit(1) of program, sometimes memory leak is diagnosed.  
	  check reports unaccounted token_char's (among other types)
	  for *some* tests, whereas check doesn't find any problems.  
	  May have to do with destructor behavior upon exit.  
	  IDEA: may need to replace exit() with throw() to ensure
	  proper stack cleanup.  

	* SOLUTION (to the above PROBLEM):
	  Problem was indeed in premature exit(), which doesn't clean up
	  the call-stack objects, and jumps straight to the end of main().
	  Exception unwinding, on the other hand, guarantees proper
	  stack clean-up.  Thus we catch a general exception at main()
	  to delay exit/returning from main until stack objects are 
	  properly destroyed.  
	  I've globally replaced exit(1) with throw std::exception()
	  to accomplish simple, yet safe, termination.  
	  In "macros.h", THROW_EXIT means "throw generic exception
	  with intention of exit(1)-ing."

	* Fixed yet another problem with pointer-classes.
	  There was an implicit conversion from never_ptr to excl_ptr
	  through excl_ptr_ref, which should not have existed, 
	  and no longer exists.  pointer_classes_test is updated
	  to reflect this.  No other compiler code is affected by this, 
	  fortunately.  (Also cleaned up much obsolete code in
	  "pointer_classes.h")

	* To fix: why do I get undefined references to __PRETTY_FUNCTION__
	  when compiling for linux?  (something to do with std::alloc?)


2005-01-14	David Fang	<fangism@users.sourceforge.net>

	* Solved global static initialization ordering problem w.r.t. 
	  stacktrace.  Previously, stacktrace was only usable for tracing 
	  functions AFTER global initializations were complete.
	  We were able to trace some static initialization calls because 
	  we got lucky, and stacktrace's static objects happened to be 
	  initialized early enough.  Now it is reliably usable to debug 
	  static initialization-time function calls.  

	* memory/pointer_classes.h: intentionally declared an explicit, 
	  private, undefined const-reference copy constructor, because
	  the default action (which was actually implicitly used!)
	  copies member-for-member, which violates exclusion.  
	  This may fix other hidden problems.  

	* Added partial specializations for util::what template, 
	  pointer, reference, const-ness.  
	  Only one module has trouble with static initializations:
	  art_parser_definition.cc, don't know why yet...

	* Some minor fixes in util template library, compile-time
	  problems discovered with gcc-3.4.0, due to improved two-phase
	  template definition evaluation.  

	* MAJOR PROBLEM: severe crashes on FreeBSD-3.4/gcc-3.4.0, 
	  currently investigating.  


2005-01-13	David Fang	<fangism@users.sourceforge.net>

	* Cleaned up the AST/* headers and definitions, with some corrections.
	  De-virtualized some methods that did not require it.  
	  Converted CHP/HSE class members to pointer-classes.  
	  Purged unnecessary repetitive declarations.  
	  Applied NEVER_NULL and INVARIANT macros gratuitously.  

	* Specialized util::what for most classes in the ART::parser
	  namespace.

	* Globally changed node::check_build's signature to
	  never_ptr<const object> check_build(context& c) const;

	* More clean up in the src/Object directory, 
	  replaced assert() with NEVER_NULL and INVARIANT macros.  

	* Added some notes regarding parser in src/parser/NOTES.  

	* Tested everything with bison-2.0 -generated parser, all good!

	* Added -ansi compilation flag to everything.  


2005-01-12	David Fang	<fangism@users.sourceforge.net>

	* Massive clean up of code in the src/Object directory.

	* Changed many function / method prototypes to pass
	  excl_ptr arguments by reference, 
	  count_ptr arguments by const reference, 
	  never_ptr arguments by const.

	* Bunch of formatting improvement for readability.  

	* Spotty documentation added, always going to be behind on this...

	* Tomorrow: the AST directory clean-up.

	* Soon: release 0.1.4


2005-01-11	David Fang	<fangism@users.sourceforge.net>

	* MAJOR BUG FIXED: memory management by pointer classes corrected.
	  Basically, ownership transfer failed in a few cases where they were
	  expected to have occured. 

	* memory/pointer_classes.h: 
	  Eliminated empty copy constructor for excl_ptr.  
	  Specialized std::_Construct for only sticky_ptr's
	  because no copy-constructor exists, and the standard containers
	  require copy-constructability.  
	  Overloading _Construct works around the problem with an 
	  explicit const-cast to guarantee that placement construction
	  (with value to assign) is done with transfer semantics.  

	* stacktrace more developed, simple and solid.
	  Added method for accessing the current output stream, 
	  using macro STACKTRACE_STREAM.
	  Eliminated construction with const char* to avoid ambiguity
	  with the constructor that accepts std::string.
	  Default what<T>::name is const char*, not const char[].  

	* list_vector_pool optionally uses util::what for producing 
	  useful verbose messages.
	  NOTE however, that automatic instantiation of what<T>::name
	  does NOT guarantee that it is statically constructed before
	  it is referenced, EVEN WITHIN THE SAME MODULE!  
	  You must explicitly instantiate the template class what
	  before it's first use in a module to guarantee correct ordering.  
	  Specialization of what<T> also accomplishes this, assuming
	  it retains a ::name member.

	* Lots more debug stacktracing code added everywhere (turned off).

	* Changed several (not all, yet) function prototypes that 
	  take excl_ptr by value and now take excl_ptr arguments by reference.  

	* ART::parser::token_char are allocated with its own 
	  static memory pool.  

	* ART::entity::data_instantiation_statement are allocated
	  with its own memory pool.  

	* Many single argument constructors were made explicit to
	  prevent promiscuous conversions.  

	* Fixed built-in datatype int initialization, guarantee
	  that memory is not immediately deallocated upon construction.  
	  (More remnants of debug code too.)

	* Next commit will clean up some debug code, promise.  
	  Will tag ARTXX-00-01-03-x.


2005-01-06	David Fang	<fangism@users.sourceforge.net>

	* MAJOR BUG: see the 2005-01-05 entry of src/NOTES.  
	  Will address the pointer class bug after isolation.  
	  (release vs. reset in destructor)
	  Much debugging code in-place is commented out.  
	  MUST FIX this before release 0.1.4.

	* Many instance reference constructors no longer need a
	  NULL index argument, just uses default of NULL.


2005-01-02	David Fang	<fangism@users.sourceforge.net>

	* New way of "naming" classes for using a "what" trait-like class.
	  By default it uses typeinfo's built-in .name() function, 
	  but may be partially specialized and overridden, especially if
	  name is mangled.  

	* Experimented around with allocating new tokens (token_char)
	  using list_vector_pool, accomplished with overloaded new/delete
	  static member operators.  
	  
	* Parser bothers freeing memory of symbol stack tokens and symbols
	  before exit(1) on error.  (Not necessary, but a good exercise.)


2004-12-24	David Fang	<fangism@users.sourceforge.net>

	* New expression class for multidimensional collections
	  of constant integers, pint_const_collection, which is implemented
	  as packed_array_generic.  (will add pbool_const_collection next)
	  Thinking of reworking expr class hierarchy...

	* IO_utils.{h,tcc}: replaced template signatures with 
	  template template parameters with simpler non-template parameter
	  class with explicit concept requirements in the implementation
	  definitions.  Added write_array for valarray, or anything similar
	  that doesn't have an iterator interface, relying only on
	  random access.  write_array is complemented by 
	  read_sequence_resize().  
	  Consider future container traits to avoid multiple definition 
	  names -- consolidation is good.  

	* multikey.{h,tcc}: added comparison and addition and subtraction
	  operator overloads.  

	* packed_array.{h,tcc}: some methods should've been public.
	  added ostream-write and istream-read methods to 
	  packed_array_generic.  
	  Minor bug fix in constructing coeffs member when size_t argument
	  is 0 (zero-detection for unsigned size-1).  


2004-12-22	David Fang	<fangism@users.sourceforge.net>

	* Eliminated last template argument of multikey, the default value. 
	  Constructors take an optional default value argument.  


2004-12-20	David Fang	<fangism@users.sourceforge.net>

	* Split multikey into declaration and definition files, 
	  actually reduced object sizes.  Also cleaned up header file
	  inclusion as a result.  

	* Added multikey_generic for variable dimension interface, 
	  which just uses valarray functionality.

	* Added packed_array_generic, updated tests to include it.

	* Finished moving structures in the util directory to the
	  util namespace.  From now on, new definitions in here
	  should be in the util namespace, or a subnamespace thereof.  


2004-12-15	David Fang	<fangism@users.sourceforge.net>

	* Revised multikey_qmap to be a specialization of 
	  multikey_map, resulting in less code bloat.  

	* More massive clean up of namespace usage in header and
	  source files.  

	* Added draft of packed_array structure (untested).  


2004-12-12	David Fang	<fangism@users.sourceforge.net>

	* Removed virtual size_t dimensions() const = 0 from
	  all children of instance_collection_base, in favor of caching
	  a const size_t dimension member per collection.  
	  This field, however, is not stored persistently, and is 
	  set upon construction as a run-time constant per collection object.  


2004-12-11	David Fang	<fangism@users.sourceforge.net>

	* Split process and channel instance collections into 
	  dimension-specific subclasses.  

	* Working on phasing out the depth (dimensions) member
	  of instance_collection_base... done!
	  But at a minor cost :(.  
	  Had to de-inline dimensions() in all instance_collections
	  to force symbols to be generated.  
	  The rememdy (if overhead is high) is to cache the 
	  dimensions in a pseudo-const field of instance_collection_base.  
	  (But wait, didn't we just eliminate it?)

	* Lessons learned: 
	  1) Inline virtual functions bad idea, because the base classes
		will be missing the symbols to inlined functions.  
	  2) Calling virtual functions of a class during its construction
		is a no-no, will result in "pure virtual method called"
		run-time abort trap.  Beware of indirect calls to 
		virtual functions through other functions as well.  

	* Some more code clean-up, making base classes persistence
	  helper methods named consistently with _base.  
	  Privatized some methods that need not be visible.  


2004-12-11	David Fang	<fangism@users.sourceforge.net>

	* Tagging this snapshot as ARTXX-00-01-03-u

	* UPDATED persistent_object management slightly.
	  Rather than force user to include static const members
	  within a class, I switched to a less intrusive technique
	  using a new persistent_traits template class.  
	  Now a type is registered by creating an instance of
	  persistent_traits<T>, which is done through a macro.  
	  A single instance of such an object will register the 
	  type (with a supplied hash-string) for the duration of the 
	  program.  (The macro call is unchanged.)  The maintainer 
	  need not declare any additional static members, not even
	  through the old PERSISTENT_STATIC_MEMBERS_DECL.  
	  The persistent_traits template definition may be specialized
	  arbitrarily, so the user need not conform to the same pattern, 
	  although it would save time for specialized maintenance.  
	  Any less effort for the maintainers helps.  


2004-12-10	David Fang	<fangism@users.sourceforge.net>

	* Massively extended the data-type instance collection and reference
	  classes into specialized type, via copy-paste-tweak.  
	  (OMG, nothing broke!)
	  Divided up data instance class files.  
	  datatype_instance_collection is now an abstract parent of
	  many children.  

	* When a datatype reference creates an instance, it now
	  correctly resolves typedefs to generate the correct class
	  of instance collections.  

	* Standardized parent calls to persistent object management
	  helper methods (collect_transient, write_object, load_object), 
	  named by default with _base.  This dramatically reduces
	  the amount of copy-paste maintenance in children classes.  

	* art_object_type_hash.h: Updated persistent object type keys
	  to reflect extensions to class hierarchy.  

	* TODO: instance reference classes that are similar should
	  be rewritten as templates for trivial generalizability.  
	  Same goes for generic instance collection patterns.  


2004-12-06	David Fang	<fangism@users.sourceforge.net>

	* More code clean-up, header file organization continued...

	* Wrapped some lexer variables and functions in ART::lexer namespace.


2004-12-05	David Fang	<fangism@users.sourceforge.net>

	* Major source tree re-organization, partitioning large header
	  files into chunks, usually pulling out the abstract base classes
	  which need to be visible, where there implementers need not
	  be visible.  
	  Implementation source files (.cc) are kept the same.  

	* Much clean-up and header file pruning.  
	  Slightly smaller objects and binaries. 
	  Slightly faster compile-time.  


2004-12-04	David Fang	<fangism@users.sourceforge.net>

	* Re-organized util/ library directory.  
	  Split many template classes into declarations and definition files. 

	* Added util/STL subdirectory with wrappers to split the 
	  standard containers into declarations and definitions files.  
	  Not terribly useful yet.  Current revision is safe
	  to switch arbitrarily between unified and split headers.  

	* Touched up ART source files to work with new headers.  
	  No functionality has changed.  


2004-12-02	David Fang	<fangism@users.sourceforge.net>

	* Further elaborated on pointer_traits.

	* Improved persistent_object_manager pointer manipulation, 
	  leveraging pointer_traits, resulting in much nicer
	  compile-time specialization and selection.  

	* Split hash_qmap and qmap into declaration (.h) and 
	  definitions (.tcc) files, inlining very few basic
	  methods in the declarations file.  
	  So far, this makes squat different in binary size because
	  the .h file still includes the entire definitions of the
	  base classes.  Will experiment further with STL wrappers...


2004-12-01	David Fang	<fangism@users.sourceforge.net>

	* art_object_instance.{h,cc}: Subclassed pbool_instance_collection
	  into dimension-specific variants.  Currently wrapped 
	  with SUBCLASS_PBOOL_ARRAY, but next revisions will 
	  clean out conditional compilation.  

	* util/indent.{h,cc}: Nifty little auto-indentation library.


2004-11-29	David Fang	<fangism@users.sourceforge.net>

	* Miraculously swapped out old pointer-class system with 
	  the new one, without breaking anything.  

	* Obsolete code is retained in util/obsolete for historical
	  purposes.  


2004-11-23	David Fang	<fangism@users.sourceforge.net>

	* Added some useful data structures to the util library.  

	* Planning restructuring of util/.  
	  Memory management (including pointer classes) relocated to
	  util/memory subdirectory.  


2004-11-06	David Fang	<fangism@users.sourceforge.net>
	
	* Debugged and finished testing the list_vector_pool allocator.  


2004-11-05	David Fang	<fangism@users.sourceforge.net>

	* Minor fixes in template code to make gcc-3.4.0 happy, 
	  changes which make code more standard-compliant. 

	* Recovered from a week of using only Apple gcc-3.3
	  while home directory on FreeBSD metwork was dead
	  on a failed hard drive.  Thank goodness for CVS 
	  (being on separate disk/server was *crucial*.)


2004-11-04	David Fang	<fangism@users.sourceforge.net>

	* art_object_instance.{h,cc}: Subclassed pint_instance_collection
	  into dimension-specific variants.  This is prototype code, 
	  switchable to old method (non-persistent) with SUBCLASS_PINT_ARRAY
	  flag defined in the header file.  
	  (Includes specialization for 0-dimensions.)
	  Will remove this switch after it is deemed stable.  

	* multikey*.h: Completed methods for read/writing multidimensional 
	  map collections to binary streams.  

	* list_vector_pool.h: simple template-based chunk allocator. 
	  Not fully debugged yet, so no warranty.  

	* Renamed some src/util files without the art_ prefix
	  because they are independent w.r.t. this project.  

	* Some general clean-up of obsolete #if 0 code-blocks.  


2004-11-01	David Fang	<fangism@users.sourceforge.net>

	* Insiginificant change.  Added CVS Id tags to all source files.   

	* Standard public class member typedefs added to 
	  hash_qmap and qmap data structures.  


2004-10-25	David Fang	<fangism@users.sourceforge.net>

	* Added auxiliary argument type to peristent object management.
	  This allows one to `escape' into a second-level of constructor 
	  tables, or pass at most one argument to initial allocation, 
	  in (class)::construct_empty().  

	* Auxiliary construction argument allows us to sub-type
	  (e.g. size_t templates) within a single registered type.  

	* art_util.{h,cc,tcc}:
	  Added more utility methods for binary I/O, for generic
	  value-sequence (list-like) persistence, and value-map (map-like)
	  persistence.  
	  Reminder that containers of pointers must still go through
	  the persistent object manager.  

	* Going to sub-type instance collections by dimensions (size_t), 
	  leaving a common abstract interface.  
	  Need this to be strongly and statically typed
	  to be able to manipulate persistent multidimensional maps.  


2004-10-23	David Fang	<fangism@users.sourceforge.net>

	* Added abstract operator wrappers around most STL
	  binary operators to enable use in virtual function table.  
	  Implemented in util/operators.h, used in Object/art_object_expr.*.

	* Copy-paste-modified pint_instance_collection to pbool counterpart, 
	  same with pbool_expression_assignment.  

	* Added to class module a boolean flag to indicate whether
	  entire module has already been (successfully) unrolled.  


2004-10-21	David Fang	<fangism@users.sourceforge.net>

	* Tag: ARTXX-00-01-03-l

	* Fixed parameter index unrolling, correctly detecting
	  unroll time errors, in multidimensional arrays, 
	  such as uninitialized or uninstantiated parameters.  

	* Hand-checked behaviour of artobjunroll on test/parser/param dir.


2004-10-19	David Fang	<fangism@users.sourceforge.net>

	* Finished first draft code for unrolling collections of
	  parameter integers, but remains largely untested.  
	  Most other existing code is unaffected.  
	  (Just needed to commit 2+k lines of code...)


2004-10-18	David Fang	<fangism@users.sourceforge.net>

	* Finished developing and testing classes for detecting
	  compacts subslices of multidimensional sparse maps, 
	  namely multikey_map.  
	  See testing class in util/test/cube_slice.h for rigorous testing.  

	* Split parameter assignments into separate compilation module, 
	  art_object_assign, used to be in art_object_connect.


2004-10-13	David Fang	<fangism@users.sourceforge.net>

	* A day of compiler infamy.  
	  GCC nightmares have forever scarred me.  

	* Minor update on how static global persistent type registry
	  is initialized.  The table itself is maintained as a
	  pointer initialized NULL, and access to it is granted through 
	  a static accessor function that allocates upon first use.  
	  Not making static table as an object because is not guaranteed
	  to be properly initialized in order, if not at all!

	* De-allocation of the type registry is managed by a little
	  hackery using a pointer class.  

	* Template method bug in gcc-3.3.x and earlier was worked around
	  by inserting keyword template in the middle of the member
	  function call.  See persistent_object_manager::get_root<T>().  

	* SEVERE PROBLEM (worked-around) with "artobjdump" and 
	  "artobjunroll" on Apple's gcc-3.3:
	  The ART::entity::module class was only referenced as a 
	  pointer, not a static object, in the main executables' source.  
	  In "artc" and "art++2obj" the module references in main()
	  were local objects, NOT pointers.  
	  Apple's gcc failed to link in the majority of modules 
	  in libart++.la, resulting in failure to properly register
	  any and all persistent types.  
	  This is evidenced by the size of the resulting executable, 
	  which ended up as 1/10 of the size it should have been.  
	  The workaround to force proper linkage was to create
	  an artificial local object of type entity::module. 
	  See art_persistent_table.cc.


2004-10-12	David Fang	<fangism@users.sourceforge.net>

	* MAJOR REWORK:
	  Extracted serializable/persistent object functionality
	  and interface into ART-independent framework classes.  
	  Now in "util/persistent.h" and "util/persistent_object_manager.h".

	* Replaced class type enumeration system ("art_object_type_enum.h")
	  with a static type registration system, where each type
	  calls a static function to register itself with the global
	  type map.  Registration requires a unique type-key (here, a 
	  short string), and a pointer to a (possibly static) allocator
	  of the mapped type.  

	* Rewrote some what() functions in object classes, because it
	  should NOT depend on any members being initialized, such as 'key'.


2004-10-10	David Fang	<fangism@users.sourceforge.net>

	* Re-typed ::write_object() with *const* persistent_object_manager&.

	* Considering re-working persistent object type-enumeration.  
	  Instead of giving each persistent type a number, 
	  give a unique key (string/hash), to avoid collisions in
	  cuncurrent development.  
	  See TODO list for more on rationale.  


2004-10-09	David Fang	<fangism@users.sourceforge.net>

	* Sub-typed param_expression_assignment (now abstract) class into 
	  pbool- and pint- specific versions, porting over old
	  functionality.  
	  Also distinguished right-hand-side expression (source) from the 
	  remaining (instance references) in the list (destinations).  
	  Greatly simplified object_list::make_param_assignment as a result.  
	  Moved type-check for parameter initialization from 
	  pint/pbool_expr::initialize into ::append_param_instance_refence.  
	  Much old code commented out, expunge in next revision.  

	* Minor update of a few old error messages; 3 test expectations
	  files in regression suite were updated, first time any of them 
	  were touched in a long time!

	* Added doxygen file header to most header and source files.  
	  As a reward, Doxygen generates really nice file dependency graphs.  
	  Also did some general header clean-up while I was at it.  
	  Updated namespaces, eliminating all references to `fang', 
	  which was only intended to be temporary.

	* Added some standard typedefs to pointer-classes:
	  value_type, pointer, reference, const_...
	  Now they may be referenced, and used for concept checking.  


2004-10-08	David Fang	<fangism@users.sourceforge.net>

	* NEWS: Returned from long hiatus working on conference paper.  

	* Tailored some multidimensional data structures
	  (multikey, and multikey_[q]map) for near-future use in
	  instance-collection classes.  

	* TODO list is somewhat more structured and comprehensible.
	  (Important!)

	* Initial attempt at unrolling parameters (pints only).  
	  Seems straightforward enough for scalars (0-D), but may
	  take some redesign for robust multidimensional support.  
	  No tests written for `artobjunroll' yet, just spot checks.  

	* Next thing to do: restructure param_expr_assignments to
	  be type-specific (only pints and pbools).  
	  Implement basic parameter assignments.  


2004-09-14	David Fang	<fangism@users.sourceforge.net>

	* Completely redone instantiation_base and subclasses, 
	  now called instance_collection_*.  
	  (~5000 lines diff)
	  instantiation_statement and instance_collection classes
	  are *tightly* coupled now.  
	  Instead of containing list of indices directly, 
	  contains list of instantiation_statements, which contain indices.  
	  Instantiation_statements need a back-reference to the
	  containing instance_collection.  
	  As a result, re-implemented handling of 
	  scopespace::add_instance and context::add_instance.  
	  Miraculously, all regression tests still pass.  

	* In class context, introduced sequential scope stack for 
	  appending sequentially managed items (instances, assignments, 
	  connections) to the right list.  
	  Remember that everything outside of definitions (even in 
	  namespaces) is in the globally sequenced list.  

	* Fundamental_type_reference now creates instantiation_statements
	  in addition to instance_collections (static methods).  

	* Multidimensional data structure interface improvements.  

	* A few more safety checks in persistent_object_manager
	  pointer I/O manipulation.  

	* Expressions objects now load (de-serialize) recursively.  

	* Code is littered with #if code blocks -- next commit will
	  be a mandatory clean-up.  


2004-09-10	David Fang	<fangism@users.sourceforge.net>

	* Major reworking of instance management: all instantiations, 
	  parameters, assignments, connections that appear outside of
	  definitions will be globally ordered into a namespace-independent
	  instance management list, to preserve source ordering.  
	  Each definition will have its own local instance management list.
	  Instance management lists will expand into sequentially scoped 
	  bodies, such as loop scopes and conditional scopes.  
	  Namespaces no longer have separate assignment or connection lists.  
	  (most affected: Object/art_context.* Object/art_object_base.*)

	* class instantiation_statement encapsulates a sequential 
	  addition of instance (possible to an array).

	* Object de/serialization interface now uses class "module" instead
	  of the root namespace.  "module" implements standard
	  de/serialization interface.  

	* Introduced new top-level object "module" which includes a
	  global namespace and a globally ordered instance management list.  
	  Note: type enumeration shifts as a result.  

	* Some more documentation on the language spec, for templates, 
	  typedefs, and type-equivalence.

	* Some general improvements and extensions to algorithm library
	  interface (functors and adapters) in the util/ directory.  

	* Minor insignificant shifts in object class hierarchy.  


2004-09-03	David Fang	<fangism@users.sourceforge.net>

	* Started a documentation directory dox/lang for the language
	  specification documentation, not to be mixed with the 
	  doxygen-generated code reference manual.  

	* Added some rather harmless data structure tests that have been 
	  sitting around for a long time (in src/util/test).  


2004-09-01	David Fang	<fangism@users.sourceforge.net>

	* Reworked connection and assignment management in class scopespace.
	  Now kept in separate lists.  (No more connection_assignment_base.)

	* Some initial groundwork for unrolling parameters and instances.  
	  Some major languauge issues need to be resolved first.  

	* Wrote and tested some data structures for multidimensional maps, 
	  both true multidimensional, and pseudo-multidimensional 
	  (with multidimensional key in a flat map).  
	  Also renamed some namespaces along the way.  

	* Note the change in email address.  :)


2004-08-21	David Fang	<fangism@gmail.com>

	* Release 0.1.3.

	* Completed object de/serialization for core classes.  
	  Recycle old type-check test inputs for object dump diff testing.  
	  New tests read in file, produce object file, and text dump.  
	  Second part takes object file and produces text dump.  
	  Text dumps are compared for consistency.  


2004-08-19	David Fang	<fangism@gmail.com>

	* Wrote majority of (semi-tested) object serialization /
	  deserialization code for Object class hierarchy.  
	  So far regression tests run clean, with self_test_no_file().  

	* The next release (0.1.3) should contain a new set of tests
	  for verifying object integrity through dump-and-load.  


2004-08-13	David Fang	<fangism@gmail.com>

	* Release 0.1.2.

	* Made parser code robust to variations in yacc/bison versions, 
	  updated test expected outputs.  This was not trivial.  
	  Works on FreeBSD yacc/bison-1.875, linux yacc/bison-1.35.  

	* Minor tweaks in configuration and Makefile.am's.  


2004-08-12	David Fang	<fangism@gmail.com>

	* Releasing 0.1.1, the completely GNU-ified version.  

	* Completed porting process, with slightly restructured test suite.
	  Short test scripts are automatically generated by the Makefile
	  and run by "make check".  
	  Tests are now run recursively by directory, and recursion 
	  terminates as soon as there is one failure in a directory.  

	* Considerable effort was spent getting the parser grammar files
	  to work with bison, whereas they were exclusively compiled 
	  with yacc only before.  Even test outputs were augmented
	  to account for differences between yacc and bison.  


2004-08-10	David Fang	<fangism@gmail.com>

	* Took the old flattened source directory, and prepared it
	  for use with automake, autoconf, and libtool.  
	  Moving sources into subdirectories meant severing files
	  from their previous revision history, which should remain
	  in the CVS repository's Attic.
