Suggested by Juraj Major.
* spot/twaalgos/sccfilter.cc: Here.
* tests/python/sccfilter.py: New file.
* tests/Makefile.am: Add it.
* NEWS: Mention the news.
Reported by Juraj Major.
* spot/twa/twa.hh: check num_sets() in prop_state_acc() so we do not
have to set it in set_acceptance(), causing trouble if set_acceptance()
is called multiple times.
* tests/python/setacc.py: New test case.
* tests/Makefile.am: Add it.
* THANKS: Add Juraj.
* NEWS: Mention the bug.
* spot/twaalgos/remfin.cc: Do not add a sink states to deterministic
weak automata, and actually apply the "weak" Fin-removal to any weak
automaton.
* tests/core/explprod.test: Add a test case for the previous patch,
but that used to fail because of this bug.
* NEWS: Mention the bug.
* spot/parseaut/public.hh, spot/parseaut/scanaut.ll: When parsing
automata read from some given FD, do not close the file descriptor, as
the caller is likely to already close it, and closing FDs twice is very
bad. This seems to have be the root of some issue we had with recent
jupyter versions, were 0MQ would crash with "Bad file descriptor"
messages. Also do not close stdin while we are at it.
* NEWS: Mention the bug.
For #189.
* NEWS: Update.
* bin/autfilt.cc: Replace stopwatch with process_timer.
* bin/dstar2tgba.cc: Replace stopwatch with process_timer.
* bin/ltl2tgba.cc: Replace stopwatch with process_timer.
* bin/ltlcross.cc: Replace stopwatch with process_timer.
* bin/ltldo.cc: Replace stopwatch with process_timer.
* bin/randaut.cc: Replace stopwatch with process_timer.
* bin/common_aoutput.hh: Implement process_timer, integrate it.
* bin/common_aoutput.cc: Integrate process_timer and implement new
print method.
* spot/misc/timer.hh: Modify timer class and timeinfo struct
i.e. add cutime (children_utime) and cstime (children_stime).
* spot/misc/timer.cc: Help code to behave as before all this.
* spot/twaalgos/dtbasat.cc: Help print_log to behave as before
all this.
* spot/twaalgos/dtwasat.cc: Help print_log to behave as before
all this.
* spot/misc/formater.hh: Add operator<< for spot::timer.
This fixes the incorrect output of tgba_determinize() reported yesterday
by Reuben Rowe.
* spot/twaalgos/simulation.cc: Do not purge unreachable states when
recording implications.
* tests/python/bugdet.py: New test case.
* tests/Makefile.am: Add it.
* THANKS: Add Reuben.
* NEWS: Mention the bug.
These were not actually printing in "SERE" mode due to a copy/paste
error. PVS-Studio seems really good at finding those. For #192.
* spot/tl/print.cc: Fix it.
* NEWS: Mention the bug.
Fix an issue reported by Tomáš Babiak, who noticed that he could not
manage to have ltl2tgba process `genltl --go-theta=N` efficiently for
larger values of N.
* spot/twaalgos/translate.hh (set_level): Reset any owned LTL simplifier
whenever the optimization level is changed.
* NEWS: Mention the bug.
Related to #188. This is a third fix that independently
makes `'utfilt --is-unambiguous -q smaller.hoa' instantaneous.
* spot/twaalgos/remfin.cc: Clean the received automaton if
necessary.
* bin/autfilt.cc: No need to call cleanup_acceptance_here() before
remove_fin() anymore.
* tests/core/remfin.test: Add an additional test.
* NEWS: Mention the change.
As observed in #188, the smaller.hoa automaton is made only of
1-state/1-self-loop SCCs, for which calling remove_fin is a complete
waste of time. This patch alone (i.e., without the other changes
suggested by #188) improves the run time of
% autofilt -q --is-unambiguous smaller.hoa
from 38s to 0.05s.
* spot/twaalgos/sccinfo.cc: If a single-state SCC has undeterminate SCC
and only one self-loop, then it is necessarily rejecting.
* NEWS: Mention the change.
Avoid calling scc_info::determine_unknown_acceptance on the product, as
suggested in #188.
* spot/twaalgos/isunamb.cc (is_unambiguous): Rewrite.
* tests/core/unambig.test: Add the automaton from #188.
* NEWS: Mention the improved function.
* spot/twaalgos/mask.cc,
spot/twaalgos/mask.hh (mask_keep_accessible_states): New function.
Suggested by František Blahoudek.
* bin/ltlcross.cc: Implement the two options.
* doc/org/ltlcross.org, NEWS: Document them.
* tests/core/complementation.test: Adjust test case.
* tests/core/ltlcross3.test, tests/core/unambig.test: More tests.
Report from František Blahoudek.
* bin/ltlcross.cc: Do not display stats for automata
that do not exist.
* tests/core/ltlcross3.test: Test it.
* NEWS: Mention the fix.
* bin/common_cout.cc (check_cout): Force a flush of cout if more than
20ms has elapsed since the last explicit flush.
* bin/common_setup.cc (setup): Untie cin and cout if the input
is not a TTY, so that cout is flush less often.
* NEWS: Mention the change.
Fixes#91.
* bin/autfilt.cc, bin/dstar2tgba.cc: Implement reading CSV files.
* bin/common_finput.cc: Fix comments.
* bin/common_aoutput.cc: Show %<, %> in help text.
* NEWS, doc/org/csv.org: Document it.
* tests/core/readsave.test: Add a short test case.
