      install back the safety check of includes.test · 0ab8dc06
      Alexandre Duret-Lutz authored
      Compilation of each header file alone, as a safety check, was removed
      when introducing "#pragma once" because we did not have to check for
      possible double inclusion.  However we still need to compile each
      header to make sure they are self-contained.
      * tests/sanity/includes.test: Compile each header.
      * tests/run.in: Export various compiler and directory flags.
      * spot/twaalgos/emptiness_stats.hh, spot/misc/mspool.hh,
      spot/misc/fixpool.hh: Include <spot/misc/common.hh>.
      * spot/misc/common.hh: Include <cassert>.
      * NEWS: Mention the fixed headers.

      parseaut: do not close fd or stdin · 49266dee
      Alexandre Duret-Lutz authored
      * 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.

      sccinfo: improve detection of rejecting 1-self-loop SCCs · ad478bd3
      Alexandre Duret-Lutz authored
      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.
