This had been broken in the 0.9 reorganization of the tgba_explicit
hierarchy. The output of 'spin -f' was incorrectly parsed as a
consequence.
* src/tgba/tgbaexplicit.hh: Introduce an alias_ map and use it.
* src/tgbaalgos/cycles.cc (tag_state): Destroy duplicate states, not
new states!
* src/tgbatest/cycles.test: Add a test case that used to segfault.
Reported by Étienne Renault.
* src/misc/unique_ptr.hh: Create unique_ptr for Spot.
* src/misc/Makefile.am: Register this new file.
* src/tgbatest/ltl2tgba.cc: Replace two calls to delete by the
utilisation of unique_ptr.
* src/tgbaalgos/simulation.cc: Replace two calls to delete by the
utilisation of unique_ptr.
* m4/lbtt.m4: Turn the missing lbtt error into a warning,
and do not configure lbtt wen --without-included-lbtt is specified.
* bench/ltl2tgba/defs.in: Abort if lbtt is missing.
* src/tgbatest/defs.in (need_lbtt): New function to skip
tests that require lbtt.
* src/tgbatest/babiak.test, src/tgbatest/ltl2neverclaim.test,
src/tgbatest/spotlbtt.test: Call need_lbtt.
* src/tgbaalgos/cycles.hh (state_info): Initialize
mark and reach to false.
* src/tgbatest/cycles.test: Use jot if seq is missing,
and a custom loop of jot is missing too.
* iface/dve2/dve2check.cc: Use postprocessor to simplify the code.
* iface/dve2/dve2check.test: Adjust to some different output values
when a counterexample is found, caused by nondeterminism introduced by
the orders of transitions.
* src/tgbaalgos/cycles.cc, src/tgbaalgos/cycles.hh,
src/tgbaalgos/isweakscc.hh: Improve .doc
* src/tgbaalgos/isweakscc.cc (weak_checker::cycle_found):
Scan the DFS backward so we only look at the cycle part.
* src/tgbaalgos/isweakscc.cc, src/tgbaalgos/isweakscc.hh: New files.
* src/tgbaalgos/Makefile.am: Add them.
* src/tgbatest/ltl2tgba.cc: Add a -KW option.
* src/tgbatest/cycles.test: Test it on a small example.
* src/bin/ltlfilt.cc: Extra input options into...
* src/bin/common_finput.cc, src/bin/common_finput.hh: ... these new
files...
* src/bin/ltl2tgba.cc: ... and use them here.
* src/bin/Makefile.am: Adjust.
* src/sanity/Makefile.am: Pass TOPBUILD to includes.test, and split the
tests in different targets.
* src/sanity/includes.test: Add include directories to bin/'s headers.
* src/ltlvisit/lbt.cc, src/ltlvisit/lbt.hh: New files.
* src/ltlvisit/Makefile.am: Add them.
* src/bin/common_output.cc, src/bin/common_output.hh: Add
support for LBT output, and reporting formulae that cannot
be output in this syntax.
* src/bin/ltlfilt.cc: Pass filename and linenum to
output_formula() for better error reporting.
* src/tgbaalgos/minimize.cc, src/tgbaalgos/minimize.hh
(minimize_dfa, minimize_wdba): Return a sba_explicit_number automaton
instead of tgba_explicit_number.
* src/tgba/tgbaexplicit.hh (declare_acceptance_condition): Fix code
so it works on sba as well.
* src/tgbaalgos/dotty.cc, src/tgbaalgos/neverclaim.cc: Specialize
for sba instead of tgba_sba_proxy.
* src/tgbaalgos/neverclaim.hh: Point to degeneralize().
* src/bin/common_cout.cc, src/bin/common_cout.hh: New files.
* src/bin/Makefile.am: Add them.
* src/bin/ltl2tgba.cc, src/bin/ltlfilt.cc, src/bin/common_output.cc:
Report error when writing to std::cout failed. This is mainly
motivated by ltlfilt not being killed by SIGPIPE on lip6's OSX
buildfarm (SIGPIPE is probably ignored when the build is started), but
it could detect other errors such as a disk full.
* src/tgbaalgos/postproc.cc, src/tgbaalgos/postproc.hh: New class to
capture the postprocessing logic.
* src/tgbaalgos/Makefile.am: Add them.
* src/bin/ltl2tgba.cc, src/bin/man/ltl2tgba.x: New files.
* src/bin/Makefile.am, src/bin/man/Makefile.am: Add them.
* src/tgbatest/spotlbtt.test: Prune the list of configurations slightly.
* src/tgbatest/spotlbtt2.test: New file.
* src/tgbatest/Makefile.am: Add it.
* bench/ltl2tgba/algorithms, bench/ltl2tgba/defs.in: Adjust to
use the new binary.
* NEWS: Update.
