	Implement cache pruning in the CGI script.

	* wrap/python/ajax/spot.in (finish): Prune the cache once in a

	* wrap/python/ajax/spot.in: Use the QUERY_STRING as a hash key to
	cache the result of the script.  Open stdout without buffering and
	redirect it to a file that we can dump later on cache hits.  Parts
	of this change are extracted from code from Pierre Parutto
	<parutto@lrde.epita.fr>.

	Fix two spurious segfaults in test cases for the Python interface.

	* wrap/python/tests/setxor.py, wrap/python/tests/bddnqueen.py:
	Clean all used bdd variables before calling bdd_done(), so that
	bdd_delref() is never called after bdd_done().  In NDEBUG builds,
	bdd_delref() does not check whether the BuDDy is running or not,

	Make state_explicit instances persistent objects.

	* src/tgba/tgbaexplicit.cc, src/tgba/tgbaexplicit.hh: Merge
	state_explicit and tgba_explicit::state.  In the past,
	state_explicit was a small object encapsulating a pointer to the
	persistent tgba_explicit::state; and we used to clone() and
	destroy() a lot of state_explicit instance.  Now state_explicit is
	persistent, and clone() and destroy() have no effects.
	* src/tgba/tgbareduce.cc: Adjust, since this inherits from
	tgbaexplicit and uses the internals of state_explicit.
	* src/tgbatest/reductgba.cc: Fix deletion order for automata.
	* src/tgba/tgba.hh (last_support_conditions_input_,
	last_support_variables_input_): Make these protected, so
	they can be zeroed by tgba_explicit.

	The gain is not very impressive.  The runtime of the first example
	in iface/dve2/README (also in dve2check.test) is 15% faster.

	* src/tgba/tgbaproduct.hh (tgba_succ_iterator_product): Move ...
	* src/tgba/tgbaproduct.cc (tgba_succ_iterator_product,
	tgba_succ_iterator_product_common): ... in these two classes.
	(tgba_succ_iterator_product_kripke): New class to speedup
	successor computation on Kripke structures.  We can assume that
	all the transitions leaving the same state have the same label.

	because Swig 2.0.2 uses ptrdiff_t and does not do the include
	itself.  In g++ most libstdc++ standard headers have been changed

	Rename is_safety_automaton() as is_guarantee_automaton() and
	implement is_safety_mwdba().

	Note: I swapped the name of safety and guarantee when I
	implemented is_safety_automaton() on 2010-03-20.  Fortunately,
	is_safety_automaton() was only used where is_guarantee_automaton()
	would have been correct.

	* src/tgbaalgos/safety.cc (is_guarantee_automaton): Rename as ...
	(is_guarantee_automaton): ... this.
	(is_safety_mwdba): New function.
	* src/tgbaalgos/safety.hh: Adjust and add documentation.

	Introduce a destroy() method on states, and use it instead of delete.

	Right now, destroy() just executes "delete this".  But in a later
	version, we will rewrite tgba_explicit so that it does not
	allocate new states (and the destroy() method for explicit state
	will do nothing).

	* src/tgba/state.hh (state::destroy): New method, to replace
	state::~state() in the future.

	We do that because the declaration of this type, which is local to

	Add LTL reductions for weak until.

	* src/ltlvisit/basicreduce.cc: Perform the following reductions.
	a U (b | Ga) = a W b
	a W (b | Ga) = a W b
	a U b | Ga = a W b
	a U b | a W c = a W (b | c)
	a W b | a W c = a W (b | c)
	a U Ga = Ga
	a W Ga = Ga

	* src/ltlast/binop.cc, src/ltlast/binop.cc: Add support for
	these new operators.
	* src/ltlparse/ltlparse.yy, src/ltlparse/ltlscan.ll: Parse them.

	* src/tgbatest/ltl2neverclaim.test: Test never claim output
	using LBTT, this is more thorough.  Also we cannot use -N
	any more in the spotlbtt.test.
	* src/tgbatests/ltl2tgba.cc: Define M and W for ELTL.
	* src/tgbatest/ltl2neverclaim.test: Test W and M, and use
	-DS instead of -N, because lbtt-translate does not want
	to translate these operators for tools that masquerade as Spin.

	* src/ltlparse/ltlparse.yy, src/tgbaparse/tgbaparse.yy,
	src/evtgbaparse/evtgbaparse.yy, src/eltlparse/eltlparse.yy: Use
	token types for %destructor and %printer.  Remove the yylex hack,

	Reverse the order of expected acceptance conditions in
	degeneralization.

	* src/tgba/tgbatba.cc (tgba_sba_proxy::tgba_tba_proxy): Build the
	list of acceptance condition in the reverse order.  The order is
	still arbitrary, but the bdd_satone() call seems to output the
	acceptance conditions that are more used first, and this helps the
	degeneralization process.

	"<->" so that "a & b -> c" is interpreted as "(a & b) -> c"
	instead of "a & (b -> c)".  The new interpretation is more

	Keep acceptance conditions on transitions going to accepting SCCs
	by default in scc_filter().

	Doing so helps the degeneralization algorithm, because it will
	have more opportunity to be in an accepting level when it reaches
	the accepting SCCs.

	* src/tgbaalgos/sccfilter.cc (filter_iter::filter_iter): Take a
	remove_all_useless argument.
	(filter_iter::process_link): Use the flag to decide whether to
	filter acceptance conditions going to accepting SCCs.
	(scc_filter): Take a remove_all_useless argument and pass it to
	filter_iter.
	* src/tgbaalgos/sccfilter.hh (filter_iter): Add the new argument
	and document the function.
	* src/tgbatest/tgbatests/ltl2tgba.cc (main): Add option use -R3
	for remove_all_useless=false and add -R3f for
	remove_all_useless=true.
	* src/tgbatest/ltl2tgba.test: Show one case where -R3f makes
	the degeneralization worse than -R3.

2099
	the FG(a)|FG(b) == F(Ga|Gb) rule by the above more generic one.
2100
2101

	Better selection of the acceptance of the initial state in SBA.

	* src/tgba/tgbatba.cc (tgba_sba_proxy::tgba_sba_proxy): Set
	cycle_start_ to start in the accepting layer of the degeneralized
	automaton if the initial state has an accepting self-loop.
	Otherwise, starts at the level of the first acceptance condition
	as previously.
	(tgba_sba_proxy::get_init_state): Use cycle_start_.
	* src/tgba/tgbatba.hh (tgba_tba_proxy::a_): Make it protected so
	that we can use it in tgba_sba_proxy::tgba_sba_proxy.
	(tgba_sba_proxy::cycle_start_, tgba_sba_proxy::get_init_state):
	Declare.

	* src/tgba/tgbatba.cc (tgba_tba_proxy_succ_iterator::sync_): Move
	the optimization step added by the previous patch outside the
	before the bddtrue check, so that it also applies to accepting
	states in SBA.

	that "ltl2ba -f 'a U (b U c)'" outperformed "ltl2tgba -f -N -R3 'a
	U (b U c)'".  With this change and the previous one, it is no
	longer the case.

	* src/tgba/tgbatba.cc (tgba_tba_proxy_succ_iterator::aut_): Store
	a pointer to the source automaton and...
	(tgba_tba_proxy_succ_iterator::sync_): ... use it in an extra
	optimization step to gather the acceptance conditions common
	to all outgoing transitions of the destination state, and pretend
	they are on the current (ingoing) transition.
	(tgba_tba_proxy::succ_iter): Pass the
	source automaton to the constructed iterator.
	* src/tgbatest/spotlbtt.test: Test -f -N -R3 -r7.
	* src/tgbatest/ltl2tgba.test: Add a test case for 'a U (b U c)'.

	ltl2tgba: apply -R3 before -D or -DS.

	* src/tgbatest/ltl2tgba.cc (main): Call scc_filter() before the
	degeneralization, because it might remove useless acceptance
	conditions.  I realized this while looking at experiments from
2157
	Rüdiger Ehlers.

	Fix random_graph() not to generate dead states.

	This is actually the third time I fix random_graph().  On
	2007-02-06 I changed the function not to generated dead states,
	but in a way that made it non-deterministic.  On 2010-01-20 I made
	the function deterministic again, but it started to generate dead
	states as a side effect.  This time, I'm making sure that dead
	states won't come again with a test-case that we should have had
	from the beginning.

	* src/tgbaalgos/randomgraph.cc (random_graph): Add an extra
	indirection array, state_randomizer[], so that we can reorder
	states indices after a random selection without actually changing
	the value of the indices used by unreachable_states and
	nodes_to_process.
	* src/tgbatest/randtgba.test: New file.
	* src/tgbatest/Makefile.am: Add randtgba.test.
