Released Cyclone Scheme 0.32.0

August 16th, 2021

Features

• Initiate major garbage collections faster after allocating a huge object (larger than 500K). This allows the system to reclaim the memory faster and keep overall memory usage low for certain workloads.
• Cyclone will no longer memoize pure functions by default.

• Added build option CYC_PTHREAD_SET_STACK_SIZE to allow Cyclone to specify a thread stack size rather than using the OS default. EG:

  make CYC_PTHREAD_SET_STACK_SIZE=1 libcyclone.a
  

Bug Fixes

• @nmeum fixed (scheme repl) to flush the output port prior to writing the prompt, guaranteeing the prompt is written at the correct time.
• Fixed fxbit-set? to properly handle negative values of i.
• Avoid unnecessary renaming of identifiers when the interpreter performs macro expansion.
• When allocating a large vector we now guarantee all vector elements are initialized before the major collector can trace those elements. This avoids the potential for a race condition which could lead to a segmentation fault.
• Ensure atomic objects are properly traced by the major garbage collector.
