#1222 new enhancement

Rework error handling to make it work better with non-POSIX functions

Reported by: sjamaan Owned by:
Priority: major Milestone: 5.1
Component: core libraries Version:
Keywords: Cc:
Estimated difficulty: medium

Description

The core system is extremely ANSI/POSIX-centered. This means for example, that ##sys#update-errno and strerror are used all over the place.

Unfortunately, this makes handling errors unnecessarily hard when dealing with native Windows functions (and potentially similar on other platforms). Michele La Monaca [gave an example of how to deal with this http://lists.gnu.org/archive/html/chicken-hackers/2014-10/msg00072.html] in a thread where he pointed out that rename-file is inconsistent across platforms when the target file already exists.

  • Milestone changed from 5.0 to 5.1

This is mostly an internal reorganisation. I think we can do this in a later version without breaking too much stuff, so there's no reason to keep this on the 5.0 milestone.
