* bench/emptchk/pml2tgba.pl: Stop checking for version start lines
depending on the Spin version. This check was never always
correct. Reported by Étienne Renault.
* bench/emptchk/formulae.ltl: Do not use + and * in the list of
formulas. Use | and & instead. The * operator was removed on
2010-01-30. Reported by Étienne Renault.
* src/tgbaalgos/randomgraph.hh: Document the fact that adding
acceptance conditions to the graph may generate graphs that do not
have any accepting cycle.
Especially with should write !(p0) and not !p0, because p0 is
usually #define'd by the user and he may have forgotten to quote
the value of the macro. This issue was discovered by Kristin
Yvonne Rozier and diagnosed by Gerard Holzmann.
* src/tgbaalgos/neverclaim.cc (process_link): Call
to_spin_string(..., true) to fully parentheses the string.
* src/tgbatest/neverclaimread.test: Add a test.
* src/tgbaalgos/weight.cc (inc_weight_handler)
(dec_weight_handler): Remove these assertions that require the
loop the be completed, and use break to exit ASAP.
* src/neverparse/neverclaimscan.ll: Make the space between `!' and
`(' optional. This fixes the patch from 2011-02-07 that made this
space mandatory...
* src/tgbatest/neverclaimread.test: Augment test case.
* src/tgba/tgbasafracomplement.cc
(tgba_safra_complement::tgba_safra_complement)
(tgba_safra_complement::succ_iter): Correct the declaration and
use of multiple acceptance conditions.
(state_complement::to_string): Output the L set, not U. The previous
code caused different states to share the same names, causing issues
with the text-based output (state with identical names get merged).
* src/tgba/tgbasafracomplement.hh
(tgba_safra_complement::acceptance_cond_vec_): Adjust type to
store BDDs.
* src/tgbatest/complementation.cc: Implement a new "-b" option
to output automata in Spot's syntax.
* src/tgbatest/complementation.test: Add a test-case supplied
by Martin Dieguez Lodeiro.
* THANKS: Add Martin.
* src/tgba/tgbasafracomplement.cc (print_safra_tree): Fix output in
case of hash collision. Use the actual states to get a number, not
their hash value.
(print_safra_automaton): Output a mapping of values to states names.
(safra_tree_automaton::get_sba): New method, used by
print_safra_automaton.
* src/evtgbaalgos/tgba2evtgba.cc (process_link): Fix prototype
to match tgba_reachable_iterator::process_link.
* src/ltlvisit/tunabbrev.hh: Add using super::visit, so that the
other visit() method are in scope when we overload one.
* src/tgba/tgbareduc.hh, src/tgba/tgbareduc.cc (start, end,
process_link): Remove these empty methods. The default
implementations are empty too, and process_link had the
wrong prototype.
* src/tgbaalgos/reductgba_sim.hh, src/tgbaalgos/reductgba_sim.cc
(start, end, process_link): Likewise.
Spot 0.7.1 used to need 190 acceptance conditions to translate the
188 literature formulae. With this patch we are down to 185.
That's not an impressive, but there are only ~20 formulae that
require more than 1 acceptance conditions; hence little room for
improvement.
* src/misc/bddlt.hh (bdd_hash): New function.
* src/misc/accconv.hh, src/misc/accconv.cc: New files.
* src/misc/Makefile.am: Add them.
* src/tgbaalgos/scc.cc (scc_map::build_map): Adjust
to record all combination of acceptance conditions occurring in a SCC.
* src/tgbaalgos/scc.hh (scc_map::scc::useful_acc): Update description.
* src/tgbaalgos/sccfilter.cc (scc_filter): Simplify acceptance
conditions that are always implied by another acceptance
conditions. Previously, we only removed acceptance conditions
that where always present in accepting SCCs.
* src/tgbatest/sccsimpl.test: New file.
* src/tgbatest/Makefile.am (TESTS): Add it.
This avoids a small regression on the size of degeneralized
automata of our usual list of literature formulae.
* src/tgba/tgbatba.hh, src/tgba/tgbatba.cc
(tgba_tba_proxy::union_acceptance_conditions_of_original_state):
New method.
* src/tgba/tgbatba.cc (tgba_tba_proxy_succ_iterator): In accepting
states, ignore only the last expected acceptance condition if its
common to all outgoing transitions AND if it is not used by any
outgoing transitions of the destination.
states).
* src/tgbaalgos/tgbatba.cc: When degeneralizing to SBA, remove the
acceptance conditions that are common to all outgoing transitions
of this state. This helps to make the degeneralization
idempotent.
* src/tgbatest/degenid.test: New test case.
* src/tgbatest/Makefile.am: Add it.
* src/tgbaalgos/save.c (process_state): Escape quotes in the
name of source and destination states. This fixes a side bug
in the upcoming degenid.test test case.
after the simulation-reduction.
Report from Tomáš Babiak <xbabiak@fi.muni.cz>.
* src/tgbaalgos/neverclaim.hh (never_claim_reachable): Take
a tgba as input.
* src/tgbaalgos/neverclaim.cc (never_claim_bfs): Call
state_is_accepting() only if this tgba turns out to be
a tgba_sba_proxy. Otherwise check the acceptance of one
outgoing transition as we do in dotty_bfs since 2011-03-05.
* src/tgbatest/ltl2tgba.cc: Do not redegeneralize before
calling never_claim_reachable() if we know the automaton is
degeneralized already.
* src/tgbatest/ltl2tgba.test: Add a test case.
Reported by Tomáš Babiak <xbabiak@fi.muni.cz>.
* src/tgba/tgbatba.cc (tgba_tba_proxy): Replace the std::map used
to record outgoing transitions by an Sgi::hash_map, and keep the
order of these transitions in a separate list.
* src/tgbatest/degendet.test: New file.
* src/tgbatest/Makefile.am (TESTS): Add it.
* THANKS: Add Tomáš and convert to utf8.
* bench/ltl2tgba/algorithms: Reduce the number of Spot configuration
tested.
* bench/ltl2tgba/Makefile.am (run, small.txt, big.txt, known.txt):
New rules.
* bench/ltl2tgba/big, bench/ltl2tgba/small, bench/ltl2tgba/known:
Add a 15min timeout to the lbtt configuration.
* bench/ltl2tgba/defs.in: Adjust variable definitions to accept
variable inderections.
* bench/ltl2tgba/parseout.pl: Add an option to output the table in
LaTeX. Also consider all formulae, not just the positive
formulae.
* bench/ltl2tgba/README: Update.
the cached result for the requests. So that it survives
the browser's cache.
(finish): Prune the cache only once per hour, and only eraes
files that are older than 2 hours.
* wrap/python/ajax/spot.in (finish): Prune the cache once in a
while. We rely on hardlinks for garbage collecting the pictures
and dot sources that may be shared by different requests.
* wrap/python/ajax/spot.in (render_dot, render_dot_maybe)
(render_automaton, render_formula): Cache the dot source, so that
we do not have to regenerate two pictures from the same contents.
* wrap/python/spot.i: Typo in the ostringstream declaration.
* 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>.
* AUTHORS: Add him.
* iface/dve2/dve2.cc (dve2_kripke::dve2_kripke): Fill
a format_filter_ array with boolean indicating whether each
variable should be printed. Ignore variable with only one
possible value.
(dve2_kripke::~dve2_kripke): Destroy it.
(dve2_kripke::format_state): Use it.
* iface/dve2/finite.test: Adjust.
generate these formulae with "genltl".
* src/tgbatest/ltlcounter/: Remove this directory.
* src/tgbatest/Makefile.am: Adjust.
* src/tgbatest/ltlcounter.test, bench/ltlcounter/run: Use genltl
to generate the formulae.
* bench/ltlcounter/README: Do not mention src/tgbatest/ltlcounter/
anymore.
* src/ltlvisit/dotty.cc: Display "L" and "R" tail-labels
for binary operators. Gather all constants and atomic
propositions in a sub-graph with "rank=sink".
* src/ltltest/genltl.cc (fair_response, ltl_counter)
(ltl_counter_carry): New functions, constructing function from
gastin.03.cav and rozier.07.cav. The LTL counter will replace the
scripts in src/tgbatest/ltlcounter/.
(X_n): New helper function.

This is also a step towards better checks for things like
__attribute__ or std::tr1.
* m4/ax_prefix_config_h.m4: New file.
* configure.ac: Call AC_CONFIG_HEADERS and AX_PREFIX_CONFIG_H.
* src/misc/Makefile.am: Install misc/_config.h.
* src/misc/random.cc, src/misc/version.cc: Include misc/_config.h.
* wrap/python/ajax/ltl2tgba.html: Adjust to use
jQuery 1.6.1 and jQuery-UI 1.8.13. Remove a useless check
of $("#autoupdate").attr("checked") since this checkbox no longer
exists.
* wrap/python/ajax/css/ui-lightness/jquery-ui-1.8.8.custom.css:
Replace by ...
* wrap/python/ajax/css/ui-lightness/jquery-ui-1.8.13.custom.css: This.
* wrap/python/ajax/Makefile.am (EXTRA_DIST): Adjust.
* src/misc/intvcmp2.cc (stream_compression_base::run):
Implement a shift-less encoding for the 1-bit and 3-bit cases.
Also declare offsets as size_t, to help 64-bit compilers.
