2021.14 Floating Rats

Steve Roe has published an interesting blog post about how the Raku Programming Language is holding up under the Muller Extreme Challenge, an algorithm designed to break computational accuracy: raku:34 python:19 extreme math. This in turn caused a discussion on /r/rakulang and in the end a Pull Request for a new feature!

Core Developments

  • Daniel Green implemented a new nqp::time op with nanosecond precision, and adapted uses of the old nqp::time_i and nqp::time_n codes to the new opcode in NQP and Rakudo as well.
  • Patrick Böker disabled Travis, AppVeyor and CircleCI for CI testing: they proved to be too unreliable and/or too slow: AzureCI is what has been in use for a while already.
  • Stefan Seifert fixed a number of spesh / NULL bugs on MoarVM, and implemented a cheaper nqp::backtrace option, which also makes backtraces consistent on all backends. Daniel Green improved on that further by removing a malloc / free per frame in a backtrace. Stefan also fixed a race condition related to continuation taking in the ThreadPoolScheduler.
  • Christian Bartolomäus made progress on unbreaking NativeCall on the JVM backend and various other types of incompatibilities between the JVM and MoarVM backend, and closed a lot of old (obsolete) issues.
  • Vadim Belman fixed a TAP-protocol inconsistency with subtests.
  • Elizabeth Mattijsen worked a lot on unicode related functionality, which was mostly internal reorganization, but which also resulted in some nice performance improvements. And they also worked on reducing binary size of several hot methods, making them more likely to be inlined.
  • Tom Browder added three new methods to DateTime: julian-date, modified-julian-date and day-fraction for easier interfacing with a lot of astronomical software.
  • And many other smaller fixes and improvements!
