ecos实时嵌入式操作系统

2003-05-01  Jonathan Larmour  <[e-mail]>

	* doc/package.sgml: Use PNGs instead of GIFs.
	* doc/jadetex.cfg: Add this to configure PDF output nicely with index
	and coloured links.

2003-02-12  Bart Veer  <[e-mail]>

	* Makefile.in, configure, testsuite/Makefile.in:
	Regenerate after acinclude.m4 update

2003-02-11  Bart Veer  <[e-mail]>

	* build.cxx (compare_and_copy):
	Work around problem with cygwin tclsh84 - "file rename" may
	spuriously report failure.

2003-02-03  John Dallaway  <[e-mail]>

	* cdl.dsp: Call tclsh rather than cygtclsh80 in custom build rule.

2002-12-22  Nick Garnett  <[e-mail]>

	* doc/.cvsignore: Added this file to ignore generated HTML files.

2002-09-21  Bart Veer  <[e-mail]>

	* cdlcore.hxx, cdl.hxx, build.cxx, component.cxx, config.cxx,
	  database.cxx, dialog.cxx, interface.cxx, interp.cxx,
	  option.cxx, package.cxx, parse.cxx, property.cxx,
	  value.cxx, wizards.cxx
	Avoid const compatibility problems with Tcl 8.4

2002-08-03  Bart Veer  <[e-mail]>

	* acinclude.m4, configure.in, Makefile.am, testsuite/Makefile.am,
	testsuite/config/default.exp:
	Rework host-side autoconf support
	
2002-03-04  Gary Thomas  <[e-mail]>

	* build.cxx (update_header_file_info): 
	Suppress include files which and in "~" - these are backup
	files and are transient.  Keeping them can break a build
	tree if the backup files are removed.

2002-02-18  Bart Veer  <[e-mail]>

	* transact.cxx (user_confirmation_required):
	Making a valuable with a user_value inactive requires
	user confirmation, it should not be done automatically
	by the inference engine.

2001-12-07  Bart Veer  <[e-mail]>

	* doc/language.sgml, doc/*.html:
	Add a footnote clarifying a particular Tcl expression
	(bug 57097). Regenerate html.

	* doc/fixhtml.tcl
	Removed, the master copy now lives in pkgconf

2001-12-06  Bart Veer  <[e-mail]>

	* cdlcore.hxx, build.cxx, interp.cxx:
	Move #include of <cctype> to common header rather than to
	individual source files, avoiding build problems with
	newer compilers. Reported by Jeff Law.

	* infer.cxx (inner_resolve):
	CdlTransaction::is_preferable_to() is not symmetric. Rearrange
	some expressions so that disabling options or making them
	inactive is subtly discouraged rather than encouraged.

2001-07-20  Bart Veer  <[e-mail]>

	* value.cxx (save):
	Complicated "requires" expressions spread over multiple lines
	were not being turned into multiline comments, leading to
	illegal savefiles.

2001-07-11  Bart Veer  <[e-mail]>

	* transact.cxx (is_preferable_to):
	Consider active changes as well as value changes.

2001-07-10  Bart Veer  <[e-mail]>

	* transact.cxx (is_preferable_to): 
	Fine-tune the determination of which of two transactions has less
	impact on the system.
	
	* infer.cxx (infer_handle_interface_value):
	Add inference engine support for constraints of the form
	(xxx == 0) and (xxx = 1), where xxx is an interface.
	
2001-07-08  Jonathan Larmour  <[e-mail]>

	* interp.cxx: include <cctype> as isspace() is used.

2001-06-21  Bart Veer  <[e-mail]>

	<merge of development work>
	* base.cxx, cdlcore.hxx, property.cxx, parse.cxx, value.cxx, refer.cxx:
	Allow an empty string to be used for parent properties, implying
	reparenting below the root

	* expr.cxx, cdlcore.hxx, infer.cxx:
	Add support for new operators implies, xor and eqv

	* func.cxx:
	Add new function is_xsubstr(), is_loaded(), is_active(),
	is_enabled(), get_data() and version_cmp()

	* doc/main.sgml: 
	Add 2001 to copyright year.
	
	* doc/language.sgml, doc/reference.sgml:
	Document the above changes

	* doc/*.html:
	Regenerate following above changes, and using newer stylesheets
	etc. 

2001-06-20  Bart Veer  <[e-mail]>

	* database.cxx, cdl.hxx:
	
	Add a verbosity flag to control whether or not certain warnings
	are issued. The main warnings of interest are inconsistencies
	between the database and the repository, e.g. packages listed
	but not actually installed, as can happen in anoncvs checkouts.

2001-05-16  Bart Veer  <[e-mail]>

	* Makefile.am: use new compiler flag support

	* configure, Makefile.in, testsuite/Makefile.in: regenerate
	
2001-05-14  Bart Veer  <[e-mail]>

	* func.cxx (get_args_count): Avoid compiler warning.
	* func.cxx (is_substr_find): fix VC++ build problem (patch
	provided by Julian) 

2001-04-27  Bart Veer  <[e-mail]>

	* doc/language.sgml:
	Added documentation on functions

	* func.cxx, Makefile.am, Makefile.in:
	New module for function support inside expressions

	* expr.cxx
	Add support for functions and the string concatenation operator. 

	* infer.cxx
	Clean-up, add support for functions, and implement more inference
	functionalitity generally.

2001-04-19  Bart Veer  <[e-mail]>

	* doc/*.sgml, *.html:
	Update as per current corporate doc conventions.

2001-02-27  Jonathan Larmour  <[e-mail]>

	* interp.cxx (locate_subdirs): Accept "cvs" as a synonym for "CVS"
	* database.cxx (new_package): Ditto.

2000-08-18  Bart Veer  <[e-mail]>

	* configure.in:
	Allow cross-compilation.

	* configure, Makefile.in, testsuite/Makefile.in:
	Regenerate.

	* base.cxx, build.cxx, cdl.hxx, cdlcore.hxx, component.cxx,
	config.cxx, database.cxx, dialog.cxx, expr.cxx, interface.cxx,
	interp.cxx, option.cxx, package.cxx, parse.cxx, value.cxx,
	wizard.cxx
	Remove C++ exception specifications, because they cause problems
	with some versions of the tools.

2000-07-06  Bart Veer  <[e-mail]>

	* conflict.cxx (get_explanation):
	Put quotes around "requires" in the conflict explanation.
	Requested by the eCos team.

2000-07-04  Bart Veer  <[e-mail]>

	* value.cxx (save):
	The comment "# This value cannot be modified here." was being
	added even for modifiable options, courtesy of some earlier
	code rearrangement.

	* config.cxx (change_package_version):
	Prevent assertion failure/crash when changing the version of a
	package that has not been loaded (not uncommon when using
	ecosconfig and confusing the order of the version and the
	package(s)).

2000-06-28  Bart Veer  <[e-mail]>

	* transact.cxx, cdlcore.hxx:
	Add details of the current transaction to the transaction callback
	class. Previously there was no way of getting hold of the current
	transaction and hence the toplevel from inside the callback
	without using statics.

	* value.cxx (set_flavor):
	Temporarily undo some of the previous value clean-ups, they were
	causing problems at the application level. The API needs to be
	changed to eliminate confusion between value and the data part
	of a bool/value pair.

2000-06-22  Bart Veer  <[e-mail]>

	* value.cxx, interface.cxx:
	Allow the flavor property to be used on interfaces. booldata
	interfaces allow the use of #ifdef to determine whether or not
	a feature is available. Clean up some of the value stuff to match,
	especially when it comes to savefiles.

	* build.cxx, cdlmisc.cxx, cdlcore.hxx:
	Add version #define support.

2000-06-15  John Dallaway  <[e-mail]>

	* cdl.dsp:
	Build libCDL to v:\cdl rather than v:\ide. Build debug versions
	against tcl82d.lib rather than tcl82.lib.

2000-06-02  Bart Veer  <[e-mail]>

	* config.cxx (load_package):
	Diagnostic function pointers were not being installed at the
	package level, so error messages due to invalid CDL were
	disappearing.

2000-05-11  Bart Veer  <[e-mail]>

	* value.cxx (implements_update_handler):
	Cope gracefully with implements properties where the destination
	is not an interface.

	* transact.cxx (clear_structural_conflicts):
	Prevent a structural conflict from being destroyed twice (only
	likely to happen during a major delete operation).

2000-04-14  Bart Veer  <[e-mail]>

	* infer.cxx (infer_set_valuable_value):
	Extend the == operator inference support to cope with bool and
	booldata options.

2000-04-11  Bart Veer  <[e-mail]>

	* infer.cxx (infer_make_active):
	Fix infinite recursion. Naughty inference engine.

	* interp.cxx (eval):
	Diagnostics enhancement tweak.

	* build.cxx (generate_config_header):
	Add a context when generating header files.

	* base.cxx (CdlLoadableBody):
	Add a context to the CdlInterpreter on creation, for better
	diagnostics.
	Do not raise errors in the internal Tcl scripts, since those
	may now get reported.

	* database.cxx (new_package):
	A single spurious subdirectory in a package should not invalidate
	the entire package.

2000-04-10  Bart Veer  <[e-mail]>

	* base.cxx, build.cxx, cdl.hxx, cdlcore.hxx, cdlmisc.cxx,
	component.cxx, config.cxx, database.cxx, dialog.cxx, expr.cxx,
	interface.cxx, interp.cxx, option.cxx, package.cxx, parse.cxx,
	property.cxx, value.cxx, wizard.cxx
	Improved diagnostics support.

	* build.cxx, property.cxx, parse.cxx:
	Allow for string vector properties with no elements. Use this
	for the include_files property.

2000-03-13  John Dallaway  <[e-mail]>

	* cdl.dsp:
	Modify libCDL custom build step to calculate the short form
	of the host tools root directory to allow rebuilding using an
	eCos installation in its default location (containing spaces).

	Use the presence of the last file generated by the
	configure phase (the ecosconfig makefile) to determine whether
	to invoke configure. This provides some	further robustness
	against failed or interrupted builds.

2000-03-08  Simon FitzMaurice <[e-mail]>
        * cdl.dsp : Modify libCDL custom build step to add --enable-maintainer-mode

2000-03-08  John Dallaway  <[e-mail]>

	* cdl.dsp:
	Modify libCDL custom build step to configure in the host tools
	directory rather than the root of the eCos repository.

2000-03-08  Simon FitzMaurice <[e-mail]>
        * cdl.dsp : Modify libCDL custom build step to avoid running configure every time.

	* build.cxx (generate_config_header):
	Fix the symbol that gets used for define properties.

	* package.cxx (get_config_header):
	Completely suppress the generation of <pkgconf/hardware.h> until
	further notice. Allow active_if properties in packages.
	Comment a need for default_value properties.
	
2000-02-11  John Dallaway  <[e-mail]>

	* cdl.dsp
	Configure and make 'quietly' for release builds to help contain
	the length of the release logs.

	* cdl.mak:
	Remove this obsolete file.

2000-02-10  Bart Veer  <[e-mail]>

	* package.cxx (parse_package):
	Allow packages to have active_if properties.
	Add a comment that default_value in a package should be allowed as
	a way of controlling enabled/disabled state.

2000-02-03  Bart Veer  <[e-mail]>

	* infer.cxx (infer_handle_reference_bool):
	Earlier fix missed yet more sub-transactions that should have been
	cancelled.

	* infer.cxx (infer_make_inactive):
	Earlier fix missed a sub-transaction that should have been
	cancelled.

	* base.cxx (save_conflicts):
	Add missing newline

	* infer.cxx (infer_subexpr_bool):
	Fix the handling of && and ||

	* infer.cxx (infer_handle_reference_value):
	Do not try modifying inactive data items, there is no point
	and it could cause an assertion failure

2000-01-25  Bart Veer  <[e-mail]>

	* config.cxx:
	Extend the savefile support to remember which packages
	belong to the hardware and which ones belong to the
	template.

2000-01-24  Bart Veer  <[e-mail]>

	* cdlcore.hxx, parse.cxx, wizard.cxx (parse_screen): 
	Change parse_property_options() to parse_options() so that it can
	be used for more than just properties

	* cdlcore.hxx, config.cxx:
	Make sure that a LocalTransaction always gets cancelled if
	things go wrong and an exception is thrown, prior to the

	object counts via the appropriate constructors and destructors.

	* database.cxx:
	Plug a one-off memory leak.

1999-12-14  John Dallaway  <[e-mail]>

	* interp.cxx:
	Modify CdlInterpreterBody::locate_subdirs(),
	CdlInterpreterBody::locate_files(),
	CdlInterpreterBody::is_directory() and
	CdlInterpreterBody::is_file() to accommodate
	spaces in paths.

1999-12-13  Bart Veer  <[e-mail]>

1999-12-09  Bart Veer  <[e-mail]>

	* cdlmisc.cxx (compare_versions):
	V1.3.1 and V1.3B6 were not compared correctly.

1999-12-03  Bart Veer  <[e-mail]>

	* build.cxx (update_header_file_info):
	If a package has no include subdirectory and no include_files
	property, search the package directory tree for anything
	resembling a header file and install that.
