* wrap/python/ajax/spot.in: Add the simulation.
* wrap/python/ajax/protocol.txt: Add the direct simulation in the
automaton simplifications section.
* wrap/python/spot.i (simulation_new): Create a function which
takes an automaton and a call to the simulation with the good
template parameter.
* wrap/python/ajax/ltl2tgba.html: Add the direct simulation
checkbox.
* wrap/python/spot.i: Fix typemap for
emptiness_check_instantiator::construct. The previous code used
to turn (None, "error") into simply ("error").
* wrap/python/ajax/spot.in: Fix handling or errors when
instantiating emptiness checks.
* wrap/python/buddy.i (__le__, __lt__, __eq__, __ne__, __ge__
__gt__): New operators for bdd.
* wrap/python/spot.i (__le__, __lt__, __eq__, __ne__, __ge__
__gt__, __hash__): New operators for formula.
(nl_cout, nl_cerr): New functions.
* wrap/python/tests/bddnqueen.py,
wrap/python/tests/interdep.py, wrap/python/tests/ltl2tgba.py,
wrap/python/tests/ltlparse.py, wrap/python/tests/ltlsimple.py,
wrap/python/tests/minato.py, wrap/python/tests/modgray.py: Adjust
to the new print syntax by using sys.output.write() or nl_cout()
instead.
* wrap/python/tests/optionmap.py: Remove all print calls.
* wrap/python/ajax/spot.in: Massive adjustments in order to work
with both Python 2 and 3. In python 3, reopening stdout as
unbuffered requires it to be open as binary, which in turns
requires any string output to be encoded manually. BaseHTTPServer
and CGIHTTPServer have been merged into http.server, so we have
to try two different import syntaxes. execfile no longer exists,
so it has to be emulated.
This also fixes two bugs where the script would segfault on
empty input, or when calling Tau03 on automata with less then
one acceptance conditions.
* wrap/python/ajax/spot.in: Create all cache files in a temporary
directory, and only rename this directory at the end. This way if
two processes are processing the same request, they won't attempt
to populate the same directory (and only one of the first of two
renames will succeed, but that is OK).
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.
* src/tgbaalgos/dotty.hh (dotty_reachable): Take a new
assume_sba argument.
* src/tgbaalgos/dotty.cc (dotty_bfs): Take a new
mark_accepting_states arguments.
(dotty_bfs::process_state): Check if a state is accepting using
the state_is_accepting() method for tgba_sba_proxies, or by
looking at the first outgoing transition of the state. Pass
the result to the dectorator.
(dotty_reachable): Adjust function.
* src/tgbaalgos/dottydec.hh, src/tgbaalgos/dottydec.cc,
src/tgbaalgos/rundotdec.hh, src/tgbaalgos/rundotdec.cc
(state_decl): Add an "accepting" argument, and use it to
decorate accepting states with a double border.
* src/tgbatest/ltl2tgba.cc: Keep track of whether the output
is an SBA or not, so that we can tell it to dotty().
* wrap/python/ajax/spot.in: Likewise.
* wrap/python/cgi-bin/ltl2tgba.in: Likewise.
* wrap/python/ajax/spot.in: Do full scc_filter for TGBA (-R3f),
and keep some extra acceptance conditions (-R3) when
degeneralizing. The converse was done.
