Optimization in Zielonka failed
under certain circumstances
todo: Devise a specialized test
for direct attr computation
* spot/twaalgos/game.cc: Correction
* tests/python/game.py: Test
Reported by Florian Renkin.
* spot/graph/graph.hh (sort_edges_of): Fix invalid read when sorting a
state without successor. Seen on core/tgbagraph.test.
* python/spot/impl.i (formula_from_bdd): Instantiate for twa_graph.
* spot/twa/twa.hh (register_aps_from_dict): Typo in exception.
* tests/python/except.py: More tests for the above.
* tests/python/bdddict.py: Typo in comment.
The fallback definition of SIZE_MAX supplied by flex was not
preprocessor friendly and prevented robin_hood.hh from doing "#if
SIZE_MAX == UINT64_MAX", as observed by Marc Espie on OpenBSD.
* spot/parseaut/scanaut.ll, spot/parsetl/scantl.ll: Define
__STDC_VERSION__ just so that the code generated by Flex
include <inttypes.h>.
* NEWS: Mention the bug.
* THANKS: Add Marc.
* spot/twaalgos/parity.cc (reduce_parity): Use the
size of the edge vector to initialize piprime1 and piprime2,
not the number of edges.
* tests/python/parity.py: Add test case, based on a report
by Yann Thierry-Mieg.
These were deprecated in C++11, and are supposed to be removed from
C++17, however gcc-snapshot just started warning about those.
* spot/misc/bddlt.hh, spot/misc/hash.hh, spot/misc/ltstr.hh,
spot/twa/taatgba.hh, spot/twaalgos/ltl2tgba_fm.cc: Here.
The current building issue is a docker issue unrelated to Spot,
so it should not prevent us from doing a release.
* .gitlab-ci.yml (rpm-pkg): Allow failure.
* spot/twaalgos/sccinfo.cc (scc_info::get_accepting_run): Ignore edges
whose colors are not part of the colors gathered in the SCC up to
deciding acceptance.
* tests/python/genem.py: New test case, reported by Clément Tamines.
* THANKS: Add him.
* NEWS: Mention the bug.
The related GraphViz issue is
https://gitlab.com/graphviz/graphviz/-/issues/2179
* spot/twaalgos/dot.cc: Avoid initial newline in title.
* NEWS: Mention the bug.
* tests/core/det.test, tests/core/dstar.test,
tests/core/neverclaimread.test, tests/python/automata-io.ipynb: Adjust
test cases.
Monitors can now be split AND completed at the same time.
Split can be called on games without providing
"synthesis-outputs" - relying on named prop.
* spot/twaalgos/synthesis.cc,
spot/twaalgos/synthesis.hh: Here
Reported by Reuben Rowe.
* spot/twaalgos/complement.cc (complement): Remove the hard-coded
simul=0 option on automata with >32 states. In 2.10 simul=0 now
implies det-simul=0, causing the regression, and most importantly it
is not needed anymore, because we have other threashold like simul-max
and simul-trans-pruning in place.
* tests/core/complement.test: Add Reuben's automaton as test case.
* NEWS: Mention the fix.
This fixes#492, based on a report from Jérôme Dubois.
* spot/twaalgos/sbacc.cc: If the initial state is in a rejecting
component, start with an initial state whose colors are unsat_mark.
* tests/core/sbacc.test: Add test case.
* tests/python/pdegen.py: Adjust it.
* spot/parsetl/scantl.ll: Diagnose delays (##n) larger than
unbounded(). Remove all checks for delays with 1 or 2 characters.
* tests/core/parseerr.test: Add a test case.
* NEWS: Mention this fix.
* spot/kripke/kripkegraph.hh, spot/misc/hash.hh, spot/twa/taatgba.cc,
spot/twa/twagraph.hh, tests/core/ngraph.cc: Replace subtraction of
pointeur minus nullptr by an explicit cast to size_t.
* spot/twa/acc.hh: Add explicit default copy assignment operator for
rs_pair.
Reported by Yuri Victorovich, on FreeBSD.
* configure.ac: Test for them.
* spot/mc/mc_instanciator.hh: Only use them if they are present.
* NEWS: Mention the fix.
* spot/twaalgos/sbacc.cc (sbacc): Define the original-states
property on the created automaton.
* spot/twaalgos/sbacc.hh: Improve documentation.
* tests/python/sbacc.py: Update test cases.
For issue #485.
* spot/tl/formula.cc, spot/tl/formula.hh: Catch min/max overflow
when the operators are constructed. Also disable travial
simplification rules that would create such overflow.
For instance x[*200][*2] will not become x[*400] anymore.
* python/spot/impl.i: Catch std::overflow_error.
* tests/core/equals.test, tests/python/except.py: Add test cases.
* spot/twaalgos/mealy_machine.cc (is_split_mealy_specialization): Hide
spl in NDEBUG.
* spot/twaalgos/synthesis.cc (apply_strategy): sp is not always used.
