Hello everyone, We are happy to announce the first release candidate of the upcoming CHICKEN 5.3.0.
CHICKEN 5.3.0rc1 is now available at this location: https://code.call-cc.org/dev-snapshots/2021/08/12/chicken-5.3.0rc1.tar.gz The SHA256 sum of that tarball is 61d59cb4f3ca226995d7dca3510c7a646c2cf1e28ebc771bf6c5177e28d14c81 This is bugfix release which takes care of several important issues. Irregex has been updated to the latest upstream (0.9.10), which fixes a few issues with bol handling and irregex-replace/all with positive lookbehind replaces all matches rather than just the first. A few bugs in the module system's handling of reexport have been fixed, as well as a few bugs in the optimization of using argvector directly in rest arguments, and a nasty issue where mutated parameters would be reset if the mutation happened in a signal handler. A nice improvement is that to build CHICKEN, on most platforms you no longer need to provide the PLATFORM variable to Make; we auto-detect the platform you're building on. Of course, for cross-compilation you'll still have to set it. Finally, we tweaked the garbage collector to avoid thrashing when the heap was almost full. This should drastically improve performance for certain usage patterns that trigger this pathological behaviour. The complete list of changes since version 5.2.0 is available here: https://code.call-cc.org/dev-snapshots/2021/08/12/NEWS Please give it a test and report your findings to the mailing list. Here's a suggested test procedure: $ make PREFIX=<some dir> install check $ <some dir>/bin/chicken-install pastiche If you want to build CHICKEN with a compiler other than the default one, just use C_COMPILER=<the compiler> (e.g., C_COMPILER=clang) on the make invocation. Of course, feel free to explore other supported build options (see the README file for more information) and actually use CHICKEN 5.3.0rc1 for your software. If you can, please let us know the following information about the environment you tested the RC tarball on: Operating system: (e.g., FreeBSD 12.0, Debian 9, Windows 10 mingw-msys under mingw32) Hardware platform: (e.g., x86, x86-64, PPC) C Compiler: (e.g., GCC 6.4.0, clang 5.0.0) Installation works?: yes or no Tests work?: yes or no Installation of eggs works?: yes or no Thanks in advance!
