Reproducible Builds: Weekly report #105

Published: May 3, 2017.


Here’s what happened in the Reproducible Builds effort between Sunday April 23 and Saturday April 29 2017:

Past and upcoming events

On April 26th Chris Lamb gave a talk at foss-north 2017 in Gothenburg, Sweden on Reproducible Builds.

Between May 5th-7th the Reproducible Builds Hackathon 2017 will take place in Hamburg, Germany.

Then on May 26th Bernhard M. Wiedemann will give a talk titled reproducible builds in openSUSE (2017) at the openSUSE Conference 2017 in Nürnberg, Germany.

Media coverage

Already on April 19th Sylvain Beucler wrote a yet another follow-up post Practical basics of reproducible builds 3, after part 1 and part 2 of his series.

Toolchain development and fixes

Michael Woerister of the Rust project has implemented file maps that affect all path-related compiler information, including “error messages, metadata, debuginfo, and the file!() macro alike”. Ximin Luo with support from some other Rust developers and contributors helped steer the final result into something that was compatible with reproducible builds. Many thanks to all involved, especially for the patience of discussing this over several months.

Ximin wrote a first-attempt patch to fix R build-path issues. It made 460/477 R packages reproducible, but also caused 3 of these to FTBFS. See randomness_in_r_rdb_rds_databases for details.
