title: Released Cyclone Scheme 0.32.0
|
|
excerpt: Added support for Alpine Linux and made several improvements to the garbage collector.
|

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.
