* src/tgbaalgos/minimize.cc (minimize_dfa): Fix detection of the
last iteration. An extra iteration case could be missed in case
where a split generates only singletons, and yet predecessor
classes need to be refined.
* src/ltlvisit/length.cc: Fix computation for ltl::multop
operator. "a&b&c" was reported with length 3, ignoring the
"&" operators, because of a typo.
* src/ltlvisit/length.hh: Fix description to correctly
reflect this change intended since 2010-01-22.
* src/ltltest/length.test, src/ltltest/length.cc: New files.
* src/ltltest/Makefile.am: Add them.
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.
* src/tgbaalgos/minimize.cc: Use is_guarantee_automaton() instead
of is_safety_automaton().
* src/tgbatests/safety.test: Rename as ...
* src/tgbatests/obligation.test: ... this, and augment the
test.
* src/tgbatest/Makefile.am: Adjust.
* src/tgbatest/ltl2tgba.cc (-O): Display whether a formula
represent a safety, guarantee, or obligation property.
* NEWS: Adjust.
server.
* wrap/python/cgi-bin/ltl2tgba.in: Starts a web server if the
script is not called as a CGI. Arrange to load libraries from
the build directory. Create the spotimg/ if needed when run as
a web server.
* wrap/python/cgi-bin/Makefile.am: Adjust build rule and clean
the spotimg directory.
* wrap/python/cgi-bin/README, NEWS: Update.
* src/tgba/tgbacomplement.hh, src/tgba/tgbacomplement.cc: Rename
as...
* src/tgba/tgbakvcomplement.hh, src/tgba/tgbakvcomplement.cc:
... these. It makes more sense since we also have
tgba_safra_complement.
* src/tgba/Makefile.am, src/tgbatest/complement.cc, NEWS: Adjust.
implementation of rational operators in a future version.
* src/ltlparse/ltlscan.ll: Do not recognize "*".
* wrap/python/cgi-bin/ltl2tgba.in: Undocument it.
* NEWS: Mention this.
* src/tgbatest/kv.test, src/tgbatest/ltl2tgba.test,
src/tgbatest/reductgba.test: Replace "*" by "&".
* src/tgbatest/ltl2tgba.cc (syntax, main): Introduce -le to select
this algorithm and -lo to add the default LTL operators. This
replace the undocumented hack to add LTL operators when the
formula with read for command-line, or the automaton was output
for LBTT.
* src/tgbatest/eltl2tgba.test, src/tgbatest/spotlbtt.test: Update
call syntax.
* NEWS: Mention -le, -lo, and -taa.
