	or FunctionCall alternatives.

	Call rasqal_query_build_declared_in.
	(rasqal_engine_move_to_graph_pattern): Helper added for:
	(rasqal_engine_get_next_result): Many changes trying to get
	optionals working.

	* rasqal_internal.h: Add query, finished, matches fields to
	graph_pattern.  Add query arg to start of
	rasqal_new_graph_pattern_from_triples and
	rasqal_new_graph_pattern_from_sequence Add variables_declared_in
	array field, optional_graph_pattern_matches_count field to query.

	* rasqal_redland.c (rasqal_redland_bind_match): Take parts
	argument and use to just bind those parts of the triple.

	* rasqal_raptor.c (rasqal_raptor_bind_match): Take parts argument
	and use to just bind those parts of the triple.

	* rdql_parser.y, sparql_parser.y: Add query arg at start of
	rasqal_new_graph_pattern_from_triples and
	rasqal_new_graph_pattern_from_sequence calls.

	* rasqal.h: Added triple parts to rasqal_triple_meta.

	* rasqal_query.c (rasqal_free_query):
	Tidy query->variables_declared_in.

2005-01-06  Dave Beckett  <Dave.Beckett@bristol.ac.uk>

	* rasqal.h: Added rasqal_triple_parts rasqal_triples_match factory
	method bind_match now takes and returns rasqal_triple_parts,
	returns 0 on failure

	* rasqal_redland.c, rasqal_raptor.c, rasqal_engine.c, rasqal.h:
	Invert return value of rasqal_triples_match factory method
	bind_match.  Now returns 0 on failure.

	* rasqal_engine.c (rasqal_engine_get_next_result): Handle failed
	constraint by moving to next match.

	* tests/sparql/part1/dawg-data-01.n3,
	tests/sparql/part1/dawg-result-003.n3: <fred@edu> to <mailto:fred@edu>

	* tests/sparql/check-sparql: Remove =NULL from roqet output to
	handle optionals

	* rasqal_query.c (rasqal_new_query): Init gp->optional_graph_pattern.

	* rasqal_internal.h: Add finished, matches, optional_graph_pattern
	to rasqal_graph_pattern Add optional_graph_pattern to
	rasqal_query.

	* rasqal_engine.c (rasqal_new_graph_pattern_from_triples): Init
	gp->optional_graph_pattern.
	(rasqal_graph_pattern_init): Init optional_graph_pattern, finished
	and matches.
	(rasqal_graph_pattern_order): Added, to sort graph_patterns in a
	query into mandatory first, optional last.
	(rasqal_engine_execute_init): Sort graph_patterns using
	raptor_sequence_sort and above helper
	Initialise query->optional_graph_pattern to the index of the first
	optional graph_pattern.
	(rasqal_engine_get_next_result): Many changes on the way to getting
	optionals working.  Track what patterns have ended with the finished
	flag, and count matches to determine when nothing matched.

2005-01-04  Dave Beckett  <Dave.Beckett@bristol.ac.uk>

	* rasqal_query.c (rasqal_new_query): Init sources sequence always.
	(rasqal_query_add_source): No need to init sources sequence here.

	* sparql_parser.y (WhereClauseOpt): Don't overwrite
	query->graph_patterns sequence, append if necessary.

	* sparql_parser.y (FromClauseOpt): Don't overwrite query->sources
	sequence, append if necessary.

	* rdql_parser.y (Query): Don't overwrite query->sources sequence,
	append if necessary.
	(TriplePattern): Append to query->triples sequence, don't
	overwrite it.

2005-01-03  Dave Beckett  <Dave.Beckett@bristol.ac.uk>

	* roqet.c (main): Declare query_string as void* to prevent type
	punning warning.

	* sparql_lexer.l, roqet.c, rdql_lexer.l, rasqal_query.c: casts
	for C++

2005-01-01  Dave Beckett  <Dave.Beckett@bristol.ac.uk>

	* roqet.c (roqet_xml_print_xml_attribute): Deleted
	(roqet_query_results_print_as_xml): Replaced with call to
	rasqal_query_results_write.
	(main): Set error and fatal_error handlers for query.
	Remove xml format warning.

	* rasqal_query.c (rasqal_query_results_write): Added docs. Declare
	own namespace stack and free up elements.

	* rasqal.h: Added rasqal_query_results_write
