+
+	* 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.

+

+
+2000-02-02  Bart Veer  <bartv@redhat.com>

+	Earlier fix missed a sub-transaction that should have been
+	cancelled.
+

+	*  infer.cxx, transact.cxx:
+	Make sure that sub-transactions are either cancelled or committed
+	before they get deleted.
+
+2000-01-26  Bart Veer  <bartv@redhat.com>
+

+	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

+
+2000-01-25  Bart Veer  <bartv@redhat.com>
+
+	* config.cxx:
+	Extend the savefile support to remember which packages
+	belong to the hardware and which ones belong to the

+	be used for more than just properties

+
+2000-01-20  Bart Veer  <bartv@redhat.com>

+	of a transaction.
+
+1999-12-17  Bart Veer  <bartv@cygnus.co.uk>
+
+	* cdl.hxx, config.cxx, database.cxx:

+	* database.cxx:
+	Plug a one-off memory leak.
+
+1999-12-14  John Dallaway  <jld@cygnus.co.uk>
+
+	* interp.cxx:
+	Modify CdlInterpreterBody::locate_subdirs(),
+	CdlInterpreterBody::locate_files(),

+
+1999-12-09  Bart Veer  <bartv@cygnus.co.uk>
+
+	* cdlmisc.cxx (compare_versions):
+	V1.3.1 and V1.3B6 were not compared correctly.
+
+1999-12-03  Bart Veer  <bartv@cygnus.co.uk>
+
+	* 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.
+
+1999-11-30  Bart Veer  <bartv@cygnus.co.uk>
+
+	* base.cxx:
+	Made the multiple conflict solution code more robust when side
+	effects occur.
+
+	* transact.cxx:
+	When a new conflict is committed and becomes global its solution
+	must be cleared, since no attempt is made to preserve the validity
+	of global solutions.
+
+	* transact.cxx (resolve):
+	Try to make sure that the inference callback gets invoked whenever
+	appropriate.
+
+	* base.cxx:
+	When resolving multiple global conflicts, fixing the first one may
+	have the side effect of fixing subsequent ones as well, resulting
+	in an assertion failure because the inference engine reported a
+	success with no changes being required. This situation is now
+	checked for.
+
+	* parse.cxx (parse_property_options):
+	Allow for a NULL options descriptor
+
+1999-11-28  Bart Veer  <bartv@cygnus.co.uk>
+

+	Add support for resolving global conflicts
+	Tidy up the transaction and transaction callback classes a bit.
+	
+	* base.cxx:
+	Add support for resolving global conflicts
+
+1999-11-26  John Dallaway  <jld@cygnus.co.uk>
+
+	* build.cxx:
+	Modify CdlToplevelBody::generate_config_headers() and
+	compare_and_copy() to accommodate spaces in the path to the
+	headers directory.
+
+1999-11-23  Bart Veer  <bartv@cygnus.co.uk>
+
+	* database.cxx (new_target):
+	command_prefix is no longer compulsory for ecos.db target entries,
+	since this is now handled in the config data. command_prefix and
+	cflags are still allowed in ecos.db for now, but will be removed
+	in future.
+
+1999-11-22  Bart Veer  <bartv@cygnus.co.uk>
+
+	* base.cxx:
+	During an unload operation a conflict may be cleared for multiple
+	reasons: the requires condition may now be satisfied, e.g
+	"requires !xxx" where "xxx" is also being unloaded; and the
+	node containing the requires property may be disappearing as well.
+	
+	* transact.cxx (save_solution):
+	If any parts of a solution involve calculated options then there
+	is no point in exposing this to the user. The re-calculation will
+	happen automatically during the next propagation.
+
+	* base.cxx:
+	* config.cxx:
+	Stop the inference engine from running when packages are loaded or
+	unloaded. The user has no opportunity to cancel or undo the
+	operation, and there may be unexpected behaviour because the
+	inference engine has no clear view of what the overall
+	configuration is going to be.
+
+	* transact.cxx (resolve):
+	Resolving one conflict may affect others in the new_conflicts
+	list. Using an iterator to examine all conflicts is a bad idea.
+	Instead each loop needs to search for a conflict that may
+	have a solution.
+
+	* base.cxx:
+	* config.cxx:
+	* cdlcore.hxx:
+	Rearrange how a CdlConfiguration gets destroyed, to allow dynamic
+	casts to be used on the toplevel as packages are unloaded.
+
+1999-11-22  John Dallaway  <jld@cygnus.co.uk>
+
+	* config.cxx:
+	Modify CdlConfigurationBody::load_package() to accommodate
+	spaces in the path to the eCos repository.
+
+1999-11-21  Bart Veer  <bartv@cygnus.co.uk>
+
+	* infer.cxx:
+	* transact.cxx:
+	* cdlcore.hxx:
+	First implementation of inference code
+
+	* conflict.cxx:
+	Added missing is_structural() member
+	
+1999-11-18  Bart Veer  <bartv@cygnus.co.uk>
+
+	* value.cxx:
+	Created a CdlSimpleValue constructor for booleans, to match the
+	assignment operator.
+
+	* expr.cxx :
+	Modify list expression evaluation code so that any terms which
+	evaluate to empty strings are discarded.
+
+1999-11-08  Bart Veer  <bartv@cygnus.co.uk>
+
+	* database.cxx:
+	Switched to ECOS_REPOSITORY environment variable.
+	
+	* transact.cxx:
+	* cdlcore.hxx:
+	Separated out normal and structural conflicts in the transaction
+	callback class.
+	
+	* value.cxx:
+	* interp.cxx:
+	* cdlcore.hxx:
+	Added new member CdlInterpreterBody::extend_comment(), for better
+	support of multiline comments in savefiles.
+
+1999-11-03  Bart Veer  <bartv@cygnus.co.uk>
+
+	* cdlcore.hxx, base.cxx, transact.cxx, value.cxx:
+	Newly loaded nodes were starting out as active, and were not being
+	turned inactive if the parent was disabled. By default nodes are
+	now inactive and there is explicit code in the transaction
+	propagate member function to check whether or not each node should
+	be active.
+
+	* Most files
+	Install the new transaction model
+
+1999-11-03  John Dallaway  <jld@cygnus.co.uk>
+
+	* value.cxx:
+	Apply patch to correct the omission of a comment char from
+	continuation lines of calculated value comments in
+	configuration save files.
+
+1999-10-25 Simon FitzMaurice <sdf@cygnus.co.uk>
+	* value.cxx:
+	Apply fix (supplied by Bart) to correct omission of comment symbol
+	from start of second and subsequent lines of split statement.
+
+1999-10-14  Bart Veer  <bartv@cygnus.co.uk>
+
+	* database.cxx:
+	* cdl.hxx:
+	Add support for new per-target commands enable and disable,
+	which provide limited control over hardware-related configuration
+	options.

+	Process per-target enable/disable commands from the database
+
+1999-10-12  John Dallaway  <jld@cygnus.co.uk>
+
+	* build.cxx (generate_config_headers):

+	which was causing system.h to not be generated.
+
+1999-10-08  John Dallaway  <jld@cygnus.co.uk>
+
+	* cdl.dsp, cdl.mak:
+
+	Link against Tcl 8.2.1.
+
+1999-10-07  Bart Veer  <bartv@cygnus.co.uk>
+
+	* value.cxx (get_widget_hint):
+	For some expressions this was corrupting the expression data,
+	because of the use of a reference rather than a pointer.
+
+1999-10-06  Bart Veer  <bartv@cygnus.co.uk>
+
+	* cdlcore.hxx, database.cxx, expr.cxx, interface.cxx, value.cxx

+	goes via the normal diagnostics routines.
+
+1999-07-22  Bart Veer  <bartv@cygnus.co.uk>
+

+	whether a number appeared as decimal or hexadecimal.
+
+1999-07-21  Bart Veer  <bartv@cygnus.co.uk>
+
+	* value.cxx:

+	Fixed some value propagation problems.
+
+	* cdlcore.hxx, value.cxx, expr.cxx:
+	Detect invalid numbers in expressions.
+	A CdlListValue object now contains a single vector of
+	CdlSimpleValue objects, not separate vectors of strings, integers
+	and doubles. This allows ordering to be preserved.
+
+	* most files:
+	Sync development version with repository, there is now
+	full value support.

+
+1999-06-02  Bart Veer  <bartv@cygnus.co.uk>
+
+	* configure:
+	Regenerated after updating toplevel acinclude.m4, new

+	* option.cxx (parse_option):

+	compatibility. 
+
+1999-03-09  Bart Veer  <bartv@cygnus.co.uk>

+
+	* interp.cxx (eval):
+	Make sure that C strings passed to the Tcl interpreter

+	* config.h.in:
+	* configure:
+	* stamp-h.in:
