2017.07 More Than One Zero

Ahoy-hoy! This week we’ve got a few nice fixes lined up for y’all:

  • the abs_n op in MoarVM now correctly turns -0e0 into 0e0 (Zoffix Znet)
  • closing an async socket now can’t cause the VM to crash. (jnthn)
  • fix a numeric overflow that could prevent a full collection from occurring (dogbert17)
  • on windows, MoarVM now correctly accepts unicode command line arguments and environment variables (thanks, nanis!)
  • the string repeat op will no longer cause the VM to panic if GC kicks in at just the right moment (samcv++, dogbert17++, and jnthn++)
  • smart matching char ranges against char ranges now works (MasterDuke17, Zoffix++)
  • a whole bunch of data races were fixed in precompilation-related code in rakudo (jnthn++)
  • smart matching a Str against a Numeric now no longer throws an exception if the Str can’t be coerced to a Numeric (Zoffix++)
  • the iterator used for implementing the rotor method used to violate the iterator protocol by pulling more values out after IterationEnd had been signalled, leading to strange exception messages (Zoffix++)
  • rational numbers used to normalize inconsistently between printing out and getting the numerator and denominator pulled out of ’em (Zoffix++)
  • a whole lot of useless coercions from int to num happened during even compiling the empty program in perl6. that number has been drastically reduced by MasterDuke17++
  • lizmat++ made Int.WHICH a bunch faster, which should make object hashes with Int keys in them faster, too.
  • I drafted a little op for MoarVM that’ll let you grab some statistics about the inner state of MoarVM. I’m intending to give info that might be interesting to have in a monitoring tool, for example if you’re running a server or web app. I’d love to hear some feedback on what pieces of data you might be interested in!
