sanitizers 0.1.2 on CRAN: Maintenance

bleach

The third release (in twelve years !!) of the sanitizers package is now on CRAN. sanitizers provides ‘true positives’ for programming errors detected by the Address Sanitizer and friends such as the Undefined Behavior Sanitizer. This permits validation of the setup when chasing such bug reports: it allows us to ascertain that the compiler (and instrumented R version) are correctly set up and the errors we expect to be reported are in fact reported. That established, a proposed fix no longer exhibiting that same error will then likely be a suitable one.

A very good resources for all things sanitizers is the Google repo at GitHub and especially its wiki.

A little over twelve years since the first release, and three years since the second one, this update brings chiefly internal package changes and maintenance. No functional changes, no behavioural changes.

The brief NEWS entry follows.

Changes in version 0.1.2 (2026-09-12)

  • Expanded README.md with additional badges, and updated URLs

  • Updated continuous integration multiple times

  • Switched to Authors@R

  • Added usage, arguments and value sections to manual page

Thanks to CRANberries, you can also look at the most recent diff to the previous release. See the project page, the github repo, and the package documentation for more details.

sanitizers 0.1.1 on CRAN: Updated and Expanded

bleach

The second release of the sanitizers package is now on CRAN. sanitizers provides ‘true positives’ for programming errors detected by Address Sanitizers and friends. This permits validation of the setup when chasing such bug reports: it allows us to ascertain that the compiler (and instrumented R version) are correctly set up and the errors we expect to be reported are in fact reported.

Almost nine years (!!) since the first release, this update brings an added integer overflow sanitizer contributed by Greg Jeffries so long ago that I had thought it was part of the CRAN releases—my bad for delaying this. It also updates programming practices by switching to symbol registration for the compiled functions. And of course several R packaging best practices have improved since the initial release so we updated a few small things throughout.

A very good resources for all things sanitizers is the Google repo at GitHub and especially its wiki.

The brief NEWS entry follows.

Changes in version 0.1.1 (2023-06-11)

  • Added integer overflow example kindly contributed by Greg Jeffries

  • Added continuous integration and badges

  • Updated package to use symbol registration for compiled code

  • Updated and edited DESCRIPTION, README and help pages for current packaging standards

  • Expanded README with usage example via r-devel-san Rocker container

Courtesy of my CRANberries, there is a diffstat report for this release. See the project page, the github repo, and the package documentation for more details.

Introducing sanitizers 0.1.0

A new package sanitizers is now on CRAN. It provides test cases for Address Sanitizers, and Undefined Behaviour Sanitizers. These are two recent features of both g++ and clang++, and described in the Checking Memory Access section of the Writing R Extension manual.

I set up a new web page for the sanitizers package which illustrates their use case via pre-built Docker images, similar to what I presented at the end of my useR! 2014 keynote a few weeks ago.

So instead of repeating this over here, I invite you to read the detailed discussion on the sanitizers page.
