AsioHeaders 1.22.1-2 on CRAN: Small Update

An new minor revision of the AsioHeaders package arrived at CRAN earlier today. Asio provides a cross-platform C++ library for network and low-level I/O programming. It is also included in Boost – but requires linking when used as part of Boost. This standalone version of Asio is a header-only C++ library which can be used without linking (just like our BH package with parts of Boost).

This minor update avoid use of (v)sprintf which CRAN now flags in r-devel (for all R builds), following the decision by Apple to deprecated it for macOS. Winston had notified me about email he had gotten for for his websocket package – also highlighting the issue for both iptools and ipaddress. As the issue ticket dialog shows I was initially a little hamfisted about replicating, falsely thinking I would need an updated compiler. But this really is ‘just’ a change in r-devel once again scanning shared libraries for symbols now warned about. Upstream has newer minor releases but they did not yet cover this; however I found a commit mentioning Xcode and snprint from three days ago which I essentially ported. We needed one more change, and that addressed the issue in websocket. But as it is good to increase the number of random acts of kindness, I also looked into iptools and ipaddress as CRAN has its eyes on them too for this. Turned out they needed simple and limited changes from sprint to snprintf so made those and sent them PRs: iptools PR #42 and ipaddress PR #79.

The short NEWS entry for AsioHeaders follows.

Changes in version 1.22.1-2 (2022-12-07)

  • Switch a handful of upstream (v)sprint uses to (v)snprintf.

Thanks to my CRANberries, there is also a diffstat report relative to the previous release.
