* src/Graph.h.in (PathElement::hasEdge): Check the correct
pointer, not the address of some member function.
* src/BuchiAutomaton.cc, src/Configuration.cc,
src/TestOperations.cc, src/TestOperations.h: Recode these files in
utf-8.
* bench/ltl2tgba/lbtt2csv.pl: Write a perl script to change the
format outputted by `lbtt' into a csv format.
* bench/ltl2tgba/Makefile.am: Add the script to EXTRA_DIST.
* src/ltlparse/ltlparse.yy: Keep the left operand of binary operator,
if the right one is erroneous. Also keep the sane beginning of
parenthesized blocks.
* src/ltltest/parseerr.test: Adjust test cases.
* NEWS: Mention it.
* wrap/python/ajax/css/loading.gif: New file.
* wrap/python/ajax/css/ltl2tgba.css (.loading): New class.
* wrap/python/ajax/ltl2tgba.html: Display loading.gif after 200ms if
the answer hasn't arrived
* wrap/python/ajax/spot.in: Do not suggest not to draw the automaton
on timeout.
* wrap/python/ajax/js/jquery.ba-dotimeout.min.js: New file.
* wrap/python/ajax/Makefile.am: Distribute it.
* wrap/python/ajax/ltl2tgba.html, wrap/python/ajax/protocol.txt:
Add options 'o' and 'p'.
* wrap/python/ajax/spot.in: Handle these, and use '-v' to check
version.
* wrap/python/ajax/ltl2tgba.html: Display the ltl3ba version, and
disable its tab when unavailable.
* wrap/python/ajax/protocol.txt: Add option for ltl3ba's version.
* wrap/python/ajax/spot.in: Implement this option, and catch
errors when ltl3ba is not installed.
* src/tgbaalgos/sccfilter.cc: tgba_explicit_numbered replace
tgba_explicit_string for the general case. This way we don't have to
prefix the result of format_state() in case to states have the same
description. We just number the states instead. For the specific
cases where the input automata are instance of tgba_explicit_string or
tgba_explicit_formula, we clone the label.
* wrap/python/ajax/ltl2tgba.html: Add a dedicated tab with
two columns of options.
* wrap/python/ajax/css/ltl2tgba.css: Support for two columns.
* wrap/python/ajax/protocol.txt: Document new options.
* wrap/python/ajax/spot.in: Handle the new options.
* wrap/python/ajax/Makefile.am: Substitude LTL3BA in spot.in.
* src/tgbaalgos/degen.cc, src/tgbaalgos/degen.hh: New files, with
most of the logic extracted from src/tgba/tgbatba.cc (SBA version).
* src/tgbaalgos/Makefile.am: Distribute these.
* src/tgbatest/ltl2tgba.cc: Use the new degeneralization instead of
the on-the-fly version.
The unicity table was mixed with the bddNode table for now
apparent reason. After the hash of some node is computed,
bddnodes[hash] did only contain some random node (not the one
looked for) whose .hash member would point to the actual node with
this hash. So that's a two step lookup. With this patch, we sill
have a two step lookup, but the .hash member have been moved to a
separate array. A consequence is that bddNode is now 16-byte long
(instead of 20) so it will never span across two cache lines.
* src/kernel.h (bddNode): Remove the hash member, and move it...
(bddhash): ... as this new separate table.
* src/kernel.c, src/reorder.c: Adjust all code.
* examples/bddcalc/parser.yxx: Rename as ...
* examples/bddcalc/parser.y: ... this.
* examples/bddcalc/parser_.cxx: New file that includes parser.c.
* examples/bddcalc/Makefile.am: Adjust.
* examples/bddcalc/parser.hxx: Delete this unused file.
* src/eltlparse/Makefile.am, src/ltlvisit/randomltl.cc,
src/ltlvisit/simplify.cc, src/ltlvisit/snf.cc, src/ltlvisit/snf.hh:
Fix GPL to version 2 or later.
This helps reducing (p&XF!p)|(!p&XFp)|X(Fp&F!p) to (p&XF!p)|(!p&XFp).
* src/tgbaalgos/ltl2tgba_fm.cc: Adjust rewriting rules of X.
* src/tgbatest/ltl2tgba.test: Add a test case.
* src/tgba/wdbacomp.cc
(tgba_wdba_comp_proxy::compute_support_conditions): Fix.
* src/tgbatest/wdba2.test: Test a formula that used to be wrongly
minimized if translated by LaCIM, because the product of a
tgbabddconcrete automaton with another automaton (done during
WDBA-minimization) use the support conditions to speed things up.
* src/tgbaalgos/minimize.cc (minimize_obligation): Delete the powerset
automaton when we return 0 because we know if the result is correct
and don't have the formulae to check it. Reported by Étienne Renault.
The previous implementation was fine to catch timeout of third-party
tools (like dot), but to good to catch timeout in Spot itself, because
Python will not deliver a SIGALRM while a native function (e.g. Spot's
translation) is running. So we fork() the Python process, with a
parent that does nothing but wait for the termination of the child or
for an alarm. On SIGALRM, the parent kills all children.
* wrap/python/ajax/spot.in: Adjust to fork.
* wrap/python/tests/alarm.py: New test file to test this
scenario in a more controled environment.
* wrap/python/tests/Makefile.am: Add it.
