v0.14.2

Fixed

• Improve actonc performance [#1119]
  • The constraint solver can have a massive performance impact on the
    compilation process, in particular if it has a very large amount of
    solutions to evaluate.
  • The number of alternative solutions had too little weight during constraint
    sorting which would result in a very large amount of potential solutions to
    evaluate. An example program took 31 minutes to compile, which after the fix
    compiles in milliseconds.
  • For a 100 constraints, with the wrong strategy we might need to evaluate
    5^100 solutions (heat death of universe etc) whereas if we do things
    correctly we can solve all constraints in perhaps 100*3 tries. Exponential
    is exponential.
• Fixed size i64 integer type is now instantiable [#1118]
• Improved str to int conversion [#1115]
• Corrected str .split and .splitlines()
• Correct DB server & client comm loop select handling [#1111]
  • Ignores EBADF and have ensured this design is correct with regards to timing
    of invalid fds.
• Drop explicit gcc dependency for Debian package [#1110]
  • Haskell GHC still depends on it though, so it still gets installed.
• Use slightly newer bsdgc / libgc version [#1112]
  • Slight build simplification as we've upstreamed some modifications.
