* 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.
* 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/spot.in: Handle the new options.
* wrap/python/ajax/Makefile.am: Substitude LTL3BA in spot.in.
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.
Syntactic implication checks may use as_bdd() to compare Boolean
formulae. By doing so, they register Boolean variables in an order
that is usially detrimental to the LTL translator. The new,
clear_as_bdd_cache() function offers a mean to unregister these
variables, so that the LTL translator will register them again in the
a more natural way.
* src/ltlvisit/simplify.hh, src/ltlvisit/simplify.cc
(clear_as_bdd_cache): New function.
* src/tgbatest/ltl2tgba.cc, wrap/python/ajax/spot.in: Call it.

code to keep it consistent with the basic rewriting checkbox.
* wrap/python/ajax/spot.in: Deal with the new option.
* wrap/python/ajax/protocol.txt: Document it.
Because this means we are running dot twice, I have added a flag that
will allow us to easily turn this off, should it prove too slow.
* wrap/python/ajax/spot.in (output_both): New variable.
(run_dot): New function, extracted from ...
(render_dot): ... here. Adjust to call run_dot for all needed format.
And ajust the output accordingly.
* src/ltlvisit/reduce.hh: Mark the file as obsolete.
(reduce): Declare this function as obsolete.
* src/ltlvisit/reduce.cc: Define SKIP_DEPRECATED_WARNING
so we can include reduce.hh.
* src/sanity/includes.test: Also use SKIP_DEPRECATED_WARNING
when compiling headers.

wrap/python/ajax/spot.in, wrap/python/spot.i: Adjust
to use ltl_simplifier.
* src/tgbatest/ltl2tgba.cc: Adjust to use ltl_simplifier,
and replace -fr1...-fr7 options by a single -fr option.
* src/tgbatest/spotlbtt.test: Adjust -fr flags accordingly.
* src/tgbatest/reductgba.cc: Do not include reduce.hh.
* src/tgbaalgos/simulation.hh: Mention the fact that this is
a "direct" simulation.
* wrap/python/ajax/ltl2tgba.html: Likewise, and change the key
to "ds".
* wrap/python/ajax/protocol.txt, wrap/python/ajax/spot.in: Adjust.
* wrap/python/ajax/spot.in: Add the simulation.
* wrap/python/ajax/protocol.txt: Add the direct simulation in the
automaton simplifications section.

template parameter.
* wrap/python/ajax/ltl2tgba.html: Add the direct simulation
checkbox.
* wrap/python/ajax/ltl2tgba.html: Scroll the the results the first
time a formula is submitted, and anytime a formula is submitted with
'enter'. Also do not animate the settings of panels when reloading
the page from a hash fragment.
* wrap/python/ajax/ltl2tgba.html: On page reload, do not ignore
fields for which no value has been set in the hash fragment.
Otherwise they will keep their default value.
Reported by Thomas Badie.
* wrap/python/ajax/js/jquery.ba-bbq.min.js: New file.
* wrap/python/ajax/Makefile.am: Distribute it.
* wrap/python/ajax/ltl2tgba.html: Include it, and
Adjust the code to update the URL's hash fragment,
and to read it.
* 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).
* wrap/python/ajax/css/ltl2tgba.css: Fix position of the "Send"
button with WebKit. The folding arrow icon had a vertical border
that overlapped with the next line.
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.
* wrap/python/ajax/ltl2tgba.html: Adjust to use
jQuery 1.6.1 and jQuery-UI 1.8.13. Remove a useless check
of $("#autoupdate").attr("checked") since this checkbox no longer
exists.
* wrap/python/ajax/css/ui-lightness/jquery-ui-1.8.8.custom.css:
Replace by ...
* wrap/python/ajax/css/ui-lightness/jquery-ui-1.8.13.custom.css: This.
* wrap/python/ajax/Makefile.am (EXTRA_DIST): Adjust.
* 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.
* wrap/python/ajax/ltl2tgba.html: Remove the auto-update button, and
enable auto-update automatically after the first submission. Add
tools tips for the "Desired Output" tabs, and the Spot logo.
Add a email icon to encourage feedback.
* wrap/python/ajax/ltl2tgba.css: fix sizes of formula field and
send button. Set position of mail icon.
* wrap/python/ajax/logos/mail.png: New logo, based on a public
domain SVG icon retrieved today from
